Brake Pads Intelligent Weighing and Pressing System(Semi-automatic)

What does the operator do in this system:
Operate from HMI:The operator primarily interacts with the system via the Human-Machine Interface (HMI). Through this interface, they have the ability to initiate, pause, or stop various production processes. For instance, they can start a new production run, halt it in case of any anomalies or for maintenance purposes. The HMI also allows the operator to input crucial parameters such as the desired temperature settings for any heating elements involved in the process, the pressure levels to be applied during pressing operations, and the cycle times for different stages. Additionally, they can access detailed production data and reports, which help in monitoring the overall efficiency and quality of the production. The operator can also adjust the speed of conveyor belts or other material handling components if needed. This comprehensive control from the HMI ensures that the operator can fine-tune the system’s operation to meet specific production requirements and respond promptly to any changing conditions.
Put the backing plates on the mold: The operator is tasked with carefully placing the backing plates onto the mold. This requires precision and attention to detail. They must first ensure that the backing plates are clean and free from any debris or defects that could affect the quality of the final product. The operator then positions the backing plates in the exact designated locations within the mold. Depending on the specific design of the mold and the production process, this could involve aligning the plates with certain grooves or markers on the mold surface. They may also need to apply a small amount of adhesive or lubricant in a controlled manner, if required by the manufacturing process, to ensure proper adhesion or ease of removal of the finished product later. This step is crucial as any misalignment or improper placement of the backing plates can lead to uneven pressure distribution during the pressing process and result in defective brake pads.
Load friction mixture box:Loading the friction mixture box is another key responsibility of the operator. The operator must first identify the correct type and quantity of the friction mixture box needed for the current production batch. They then transport the box to the loading area of the system. This may involve using a forklift or a handcart, depending on the size and weight of the boxes and the layout of the production facility. Once at the loading area, the operator carefully inserts the box into the designated feeder or hopper. They need to ensure that the box is properly seated and that the connection or opening for dispensing the friction mixture is aligned correctly. The operator may also need to activate a sensor or a switch to signal to the system that a new box has been loaded and is ready for use. This step is essential as it provides the raw material for the production of the brake pads, and any errors in loading could disrupt the entire production process.
Other procedures will be done by machines: After the operator has completed their tasks, the machines take over and perform a series of complex procedures.
★ 2 press machines each system: Each system is equipped with 2 press machines. These press machines are highly automated and precisely calibrated. They are designed to apply a specific amount of pressure to the friction mixture and backing plates within the mold. The press machines can adjust the pressure based on the type of brake pad being produced and the specific requirements of the manufacturing process. They also have built-in safety features to prevent overloading or any damage to the molds or the press itself. The machines are synchronized to work in harmony, ensuring that the pressing process is carried out uniformly across all molds and cavities. They can also monitor the pressure and temperature during the pressing process and make real-time adjustments if necessary to maintain the quality and integrity of the final product.
★ Suitable for mold with different layout 2×2/3×3/3×4/4×4/2×6…:The system is extremely versatile and can accommodate molds with various layouts. Whether it’s a 2×2 layout, which might be suitable for smaller or more specialized brake pads, or a larger 4×4 layout for mass production of standard-sized brake pads, the machines can handle it. The system automatically adjusts its parameters and operations based on the specific mold layout. It can precisely control the distribution of the friction mixture into each cavity of the different layouts, ensuring that the correct amount is dispensed. The pressing process is also optimized for each layout, taking into account the number and size of the cavities. This flexibility allows the system to produce a wide range of brake pad types and sizes without the need for extensive reconfiguration.
★ Friction mixes is loaded by small boxes: The friction mixture is supplied in small boxes, which offers several advantages. The small boxes are designed to hold a specific quantity of the friction mixture, which helps in maintaining accurate dosing. The system is equipped with mechanisms to handle these small boxes. When a box is loaded, the system can detect the presence of the box and initiate the process of extracting the friction mixture. It can control the rate at which the mixture is dispensed into the molds, ensuring a consistent and even distribution. If a box runs out during the production process, the system can signal the operator to load a new one, allowing for a continuous production flow. This method of loading the friction mixture also helps in reducing waste and ensuring the freshness and quality of the mixture used in each batch of brake pads.
Details of Intelligent Brake Pads Weighing and Pressing System
Auto Material Weighing and Dosing:
The automated material weighing and dosing system is a crucial component of the production process. It offers two options for loading the friction mixes. The small boxes, each with a capacity of around 50kg, are convenient for handling smaller batches or when a more precise quantity control is needed. These boxes are designed to be easily loaded onto the system and are made of durable materials to withstand the rigors of the production environment. On the other hand, the 800L big volume tank is ideal for large-scale, continuous production. It is equipped with level sensors and a precise dispensing mechanism to ensure a steady and accurate flow of the friction mix. The system can seamlessly switch between these two loading methods based on production requirements. The weighing and dosing process itself is highly accurate, with sensors that can measure the material down to a fraction of a gram. This precision is essential for maintaining the quality and consistency of the brake pads being produced.
Auto Pre-Pressing In Material Tray in the weighing system:
Once the material is weighed and dosed into the material tray within the weighing system, the automatic pre-pressing mechanism kicks in. This pre-pressing is carefully designed to compact the friction mix evenly. The pre-pressing force is adjustable, depending on the specific characteristics of the material. For example, if the mix contains a higher proportion of coarse particles, a higher pre-pressing force may be required to ensure proper compaction. The pre-pressed material in the tray is then ready for the next stage of the process, and its compacted state helps to prevent any spillage or misalignment during transportation and further processing.
Auto Material Feeding & Flattening:
The automatic material feeding process is a highly coordinated operation. The pre-pressed material tray is transported to the feeding area by a conveyor system that is synchronized with the overall production cycle. The feeding mechanism uses robotic arms or a combination of conveyors and pushers to transfer the material into the pressing area. Once in the pressing area, the flattening device, which may consist of precision rollers or adjustable press plates, flattens the material to the exact thickness required for the brake pads. The thickness is continuously monitored by sensors, and any deviations are immediately corrected by the system. This ensures that each brake pad has a consistent thickness and surface finish, which is vital for its performance.
Auto Mold Release Spraying and Cleaning:
To ensure the smooth operation of the molds and the easy removal of the finished brake pads, the system has an automatic mold release spraying and cleaning mechanism. Before each pressing cycle, a precisely calibrated spray nozzle sprays a thin and even layer of mold release agent onto the mold surfaces. This agent is carefully selected to provide optimal release properties without affecting the quality of the brake pads. After the pressing is complete and the brake pads are removed, the molds are cleaned. The cleaning process involves a combination of high-pressure water jets, which can remove loose debris, and rotating brushes that scrub the mold surfaces to eliminate any residual material. Additionally, a solvent may be used to dissolve any remaining adhesive or contaminants. This automated process not only extends the life of the molds but also reduces the downtime between production cycles.
Manually put the backing plates:
The placement of the backing plates is a manual operation that requires attention to detail. The operator first inspects the backing plates to ensure they are free from any defects or contaminants. Then, using a set of handling tools or guides provided by the system, the operator carefully places the backing plates into the molds. The correct alignment and positioning of the backing plates are crucial, as any misalignment can lead to uneven pressure distribution during the pressing process and result in defective brake pads. The operator may also need to apply a small amount of adhesive or lubricant to the backing plates, depending on the production requirements.
Auto Finished Brake Pads Grabbing:
After the brake pads have been pressed and are ready for removal, the system’s automatic grabbing mechanism takes over. This mechanism consists of robotic arms equipped with specialized grippers. The grippers are designed to gently and securely hold the brake pads without causing any damage. They can adjust their grip based on the size and shape of the brake pads, ensuring a firm hold. The robotic arms are programmed to move in a precise path, carefully lifting the brake pads from the molds and transporting them to the next stage of the production line, such as a quality inspection area or a packaging station. This automated process improves the overall efficiency of the production line and reduces the risk of human error in handling the finished products.
Any layout of molds is suitable to weigh and press:
The system’s flexibility allows it to work with molds of any layout. Whether it’s a simple rectangular layout like 2×2 or a more complex configuration such as 4×4 or other custom designs, the system can handle the weighing and pressing operations with ease. The weighing system is equipped with advanced software and sensors that can accurately measure and distribute the friction mix into the cavities of different mold layouts. The pressing machines are also adjustable, with the ability to apply the correct amount of pressure evenly across the different cavity arrangements. This adaptability enables the production of a wide variety of brake pads with different shapes and sizes, catering to the diverse needs of the market.
2 press machines can produce 2 Different Models brake pads:
The two press machines in the system are configured to produce two different models of brake pads simultaneously. Each press machine has its own set of controls and parameters that can be adjusted independently. For example, one press machine may be set to produce a standard brake pad model with specific pressure, temperature, and pressing time requirements, while the other press machine can be configured to produce a high-performance brake pad model with different settings. The system’s control software coordinates the operation of the two press machines to ensure that both models are produced with high quality and consistency. This dual-model production capability significantly increases the production efficiency and flexibility of the system, allowing manufacturers to meet the demands of multiple customers or product lines without the need for extensive reconfiguration or downtime.
Manipulators travels in front of the system:
The manipulators, which are an essential part of the system, travel in front of the production line. These manipulators are highly versatile and can perform a variety of tasks. They are equipped with advanced sensors and control systems that allow them to interact with different components of the production process. For example, they can pick up and transport the material trays from one station to another, assist in the loading and unloading of the friction mixes, and even help in the placement of the backing plates if needed. Their movement in front of the system is carefully coordinated to ensure a smooth flow of materials and operations.
Weighing system with 2 matieral bins with 4 feeders on each:
The weighing system consists of two material bins, each with four feeders. These bins and feeders are designed to handle two different types of materials. The material bins are made of high-quality, corrosion-resistant materials to ensure the integrity of the stored materials. The feeders are precisely calibrated to dispense the materials in the correct amounts. Each feeder can be individually controlled, allowing for a wide range of material combinations and ratios to be achieved. This setup provides great flexibility in the formulation of the friction mixes, enabling the production of brake pads with different properties and characteristics.
Material Bins: There are 2 bins, enabling the weighing of 2 different materials.
The two material bins are a key feature of the weighing system. They are strategically placed to allow for easy access and loading of the different materials. The bins are designed with lids or covers to prevent any contamination or spillage. They are also equipped with level sensors that can monitor the amount of material remaining in the bins. This information is relayed to the system’s control panel, which can then prompt the operator to refill the bins when necessary. The ability to weigh two different materials separately is crucial for creating the precise formulations required for high-quality brake pads.
Weighing Range: Ranges from 40 to 400 grams (customizable).
The weighing range of the system is adjustable from 40 to 400 grams, and this flexibility is a significant advantage. It allows for the precise measurement of both small and relatively large amounts of materials. The system’s sensors and control mechanisms are designed to handle this wide range with high accuracy. For example, when a formulation requires a small amount of a particular additive, the system can accurately measure 40 grams or less. On the other hand, for the main components of the friction mix, it can handle up to 400 grams. The customizable nature of the weighing range means that the system can be adapted to different production requirements and material formulations.
Weighing Tolerance: ±0.5 gram
The weighing tolerance of ±0.5 gram is an extremely tight margin of error. This high level of precision is essential for maintaining the consistency and quality of the brake pads. Even a small deviation in the weight of the materials can affect the performance and durability of the final product. The system’s weighing sensors and calibration mechanisms are constantly monitored and adjusted to ensure that the measured weights are within this tolerance. This precision is what sets this production system apart and enables the production of high-quality brake pads that meet or exceed industry standards.
