Description

Technical Field

[0002] Brake pads are also called brake shoes. In the braking system of a car, brake pads are the most critical safety parts and play a decisive role in the braking effect. Brake pads are generally composed of steel plates, bonding insulation layers and friction blocks. Among them, the friction blocks are composed of friction materials and adhesives. When braking, the friction blocks are squeezed on the brake disc or brake drum to produce friction with it, thereby achieving the purpose of slowing down the vehicle. It can be seen that friction materials are a very important component of brake pads during the manufacturing process and use process.

[0087] In S3, at the first adsorption station, with the help of the robot gripper 4; first, the transport mechanical claw 41 grabs the ballast mold 32, the profiling electromagnet 34 adsorbs the ballast mold 32, and the detection sensor 40 detects the positive and negative state and position of the ballast mold 32 and adjusts it to be sent to the steel back loading station; then, the steel back replacement cylinder 42 pushes the pre-loaded steel back carrier close to the loading station to realize the replacement of the steel back carrier, and the steel back lifting top plate 44 pushes the steel back part 45 up; secondly, the steel back suction cup 43 is used to place the steel back part 45 on the ballast mold 32;

[0090] The present invention realizes full automation, short assembly line, accurate weighing, reasonable connection of working procedures, and dust-free and thorough cleaning by using spiral wind and DC wind. The truss knocking part 27 realizes vibration drop.

The floating proximity sensor 50, floating spring 51, floating base 52, floating electromagnet 53, guide rod lifting cylinder 54, and finished material frame 55 have good flexibility and compatibility.

[0091] As a specific example, the complete machine of the present invention includes 2 sets of truss feeding mechanisms, 4 sets of steel back feeding mechanisms, 2 sets of weighing mechanisms, 2 sets of finished product conveyor lines, 2 sets of gantry module stacking mechanisms, four pressing machines, one set of protective fences and one set of robot grippers.

[0092] The equipment automatically mixes the materials and puts them into the brake pad pressing mold that has been sprayed with release agent. The robot spreads and taps the materials. After the tapping action is completed, the robot reaches the steel back feeding area and uses an electromagnet to absorb the steel back and put it into the mold slot. After the pressing machine completes the pressing of the brake pad, the robot takes out the finished brake pad and puts it on the conveyor belt until the stacking mechanism completes the stacking of the brake pad and repeats the cycle. During the process, the pressing machine has intermittent working time, so four pressing machines are configured, and the robot, feeding mechanism, weighing mechanism, and finished product conveying related mechanisms work continuously.

[0093] The material spreading motor, after the manipulator locates through communication, inserts the material spreading gripper into the die slot, and then the motor drives the four material spreading grippers to work synchronously;

[0094] After the robot is positioned through communication, the material-beating board is directly above the mold, and the robot moves downward to complete the material-beating;

[0095] After the profiling electromagnet and the pressing machine complete the brake pad pressing work, the robot communicates and locates and automatically turns on the electromagnet power to complete the material collection.

[0096] This action realizes two material spreading, one material beating, one steel back delivery and one brake pad collection.

[0097] After the first batch of formula materials is put into the hopper for the first time, the robot spreads the materials, and then the second formula materials are put in. The robot spreads the materials for the second time and completes the material beating and steel backing input. After the brake pad pressing equipment completes the pressing, the robot takes the materials, and the above actions are repeated.

[0098] During the operation of the six-axis robot, the pressing equipment remains stationary, and the robot achieves precise positioning through fixed program calculation and PLC control.

[0099] The steel backs in the steel back feeding mechanism are arranged according to the mold size, which can achieve precise positioning of the steel backs and ensure the accuracy of the steel back placement.

[0100] The steel back suction cup has a lifting screw at the bottom motor which is connected to a lifting push plate. Each time the steel back is discharged, the motor rotates at a fixed speed to store the steel back and transport it to the area to be grabbed. When the sensor senses the steel back, the motor stops feeding and the steel back is manually fed.

[0101] The steel back lifting top plate and the push plate are equipped with sensors in the horizontal direction. After the steel back is in place, the cylinder pushes out to complete the steel back loading preparation.

[0102] Steel back replacement cylinder, two sets of steel back feeding structure with a slider mechanism added to the bottom to complete gapless steel back feeding by the movement of two sets of replacement cylinders.

[0103] An interrupt cylinder design is added to the weighing mechanism to avoid weighing errors caused by the length of the material storage in the feeding pipe and ensure weighing accuracy. (The upper hopper weighing sensor senses that the feeding conditions are met, and the interrupt cylinder is equipped with a baffle to prevent the material from continuing to leak. At the same time, the interrupt cylinder baffle plays a role in preventing the powder from falling when the hopper at the bottom moves after the weighing is completed and the hopper is driven by the bracket to feed the material).

[0104] The weighing interrupts the cylinder, and when the weighing sensor senses that the material has reached the standard, the cylinder closes and stops feeding.

[0105] The truss feeding mechanism consists of a feeding hopper, a mold cleaning device and a release agent spraying device, which reduces the number of silos and ensures that the weighing meets the pressing rhythm requirements.

[0106] Servo motor control, using rack and pinion to achieve reciprocating motion.

[0107] Release agent spraying and mold cleaning, the brush roller is driven by a common motor to roll and clean the mold, and the tail release agent sprayer performs atomization spraying. After completing the action, the first formula material is added.

[0108] Two sets of feeding modules are used to feed specific formulas respectively to prevent weighing errors and reduce mixing. The feeding modules are driven by standard cylinders and stabilized by two sets of guide shafts on both sides.

[0109] The truss interrupts the cylinder to control the push plate. A weighing sensor is installed in the weighing bin above. When the material weight reaches the requirement, the cylinder is closed to ensure the accuracy of weighing.

[0110] Truss unloading cylinder, the cylinder drives the push plate through reciprocating motion to realize the opening and closing of the unloading port.

[0111] The truss feeding port is customized according to the brake pad pressing mold to prevent the feeding from being skewed;

[0112] Truss temporary storage silo, the formula material is temporarily placed in the silo after weighing and transported to the top of the mold.

[0113] Gantry module palletizing mechanism:

[0114] Electric slide, two sets of finished electric slides are selected and controlled by PLC for precise transportation and palletizing.

[0115] The PLC counts during the process;

[0116] The guide fixing plate is equipped with a laser sensor at the front end. When the brake pad reaches the designated position, the sensor is triggered and the guide rod cylinder starts to descend to perform the lower operation.

[0117] The guide rod lifts the cylinder, and the bottom is connected to the electromagnet by a floating spring as the main floating mechanism and detected by a proximity sensor. When the cylinder descends, the sensor is triggered and the electromagnet opens to absorb the brake pad.
