Description

Technical Field

[0001] The invention relates to the technical field of brake pad processing, and in particular to a brake pad product quality detection device. Background Art

[0002] Referring to the patent document with application number "CN202211126908.8", entitled "A grinding device for automobile brake pads", this patent document has a clamp installed on the mounting shell and the mounting ring to clamp the brake pad for processing, and the rotating disk rotates to bring the clamp to the processing area for processing, and the rotating disk is installed with multiple clamps, so that the brake pad can be replaced outside the processing area, which improves the safety of the equipment and will not affect the processing, so that processing and material replacement can be carried out at the same time, improving production efficiency.

[0003] The prior art achieves the detection and grinding effect by fixing most brake pads on a circular support column and rotating the brake pads to make them contact with the grinding pads. Since the brake pads are fixed as a whole by limit blocks and L-shaped positioning blocks, and when the prior art detects the brake pads, the horizontal orientation of the detected surfaces of some brake pads is incorrect, resulting in the brake pads being difficult to be detected during the detection process and missing the grinding process, and further missing the grinding process of the uneven brake pad contact surface, resulting in safety hazards during the subsequent use of such brake pads. Even if it is found at a later stage that the contact surface of such brake pads is not level enough, the brake pads need to be reworked, thereby reducing the use efficiency of the brake pads.

[0021] Reference Figure 1-Figure 12 A brake pad product quality inspection device includes a conveyor platform 1. The conveyor platform 1 is a device in the prior art for collecting brake pads 13 that need to be polished in the factory, and the collected brake pads 13 are polished through the transportation of a first conveyor belt 11. The brake pad 13 is an important component of the automobile brake system in the prior art. It is usually composed of a combination of multiple materials, and is composed of an adhesive, a heat insulation layer and a friction material. The main purpose is to polish the friction material exposed on the surface. Due to the long-term use of the brake pad 13, hard objects such as pebbles will be splashed during the driving process of the wheel, and potholes and damage will appear on the surface of the brake pad 13 through the impact of speed and braking. In the subsequent use process, the braking distance of the brake pad 13 will be reduced, thereby increasing the safety risk of automobile braking.

[0022] It should be noted that the hole is a unique feature of the brake pad 13, which is usually a feature of brake pads 13 of different specifications and models. The first conveyor belt 11 is a common transportation structure used to transport the brake pad 13 in the prior art. It is composed of a belt and a belt roller and has a good transportation capacity. The clamping table 2 is mainly used for correction of the brake pad 13 before grinding to ensure that the ground contact surface is correct. At the same time, it has the effect of flipping the brake pad 13, which can effectively reduce the accumulation of debris on the grinding and polishing table.

[0023] Reference Figure 3 The first conveyor belt 11 is used as the main transport component of the conveyor platform 1. The first limiting strips 12 of the planned transport structure are arranged on both sides thereof, and the first limiting strips 12 are adapted to the first fixed end 16 described below. The first limiting strips 12 can effectively prevent the transport structure from deflecting, thereby causing the brake pads 13 to separate from the conveyor platform 1 and need to be manually collected and transported again.

[0024] It should be noted that the first slider 14 arranged on both sides of the conveyor platform 1 is an auxiliary component, which is driven by an external driving mechanism and has a moving speed the same as that of the first conveyor belt 11, ensuring the longitudinal movement of the first slider 14 and reducing the offset of the brake pad 13 on the first conveyor belt 11.

[0025] Furthermore, the clamping mechanism provided on the first slider 14 is mainly used to restrict the brake pad 13 on the first conveyor belt 11 to prevent the bottom of the brake pad 13 from deflecting due to the movement of the first conveyor belt 11. The overall structure of the clamping mechanism is made of aluminum alloy and aluminum material. The aluminum alloy material has good strength and can effectively improve the control of the brake pad 13. The telescopic rod 15 on the clamping mechanism is mainly made of aluminum material, which has good lightness, and is composed of a plurality of telescopic sleeves. The sleeves are fixed by auxiliary parts. The auxiliary parts are connecting rods, and the two ends of the connecting rods connect the sleeves to ensure the normal telescopic function of the telescopic rod 15. The first fixed end 16 and the second fixed end 17 on the clamping mechanism are spliced ​​with each other by screws, and the second fixed end 17 can change the inner diameter of the first fixed end 16 by adjusting the screws, thereby improving the effect of the first fixed end 16 on restricting the brake pad 13. The two are spliced ​​to form the main structure of the clamping mechanism; The adjusting screw 18 arranged at the tail end of the first slider 14 is mainly used to change the telescopic length of the telescopic rod 15. The adjusting screw 18 is a screw with twenty-five threads in the prior art, and the adjusting screw 18 is connected to the telescopic rod 15 through a meshing gear. When the adjusting screw 18 rotates, the connection between the telescopic rod 15 and the meshing gear can be triggered, thereby completing the length adjustment of the telescopic rod 15.

[0026] Reference Figure 2 and Figure 4 One end of the clamping table 2 is horizontally aligned with the conveying table 1 and is arranged at the bottom of the first conveyor belt 11, so as to effectively receive the brake pad 13 on the first conveyor belt 11. The fixed motor 21 arranged on the clamping table 2 is a prior art. Its power output end is connected to an external power supply, and then controlled by computer numerical control technology. Computer numerical control technology generally uses a dedicated computer and is equipped with an interface circuit, which can realize the control of the actions of multiple numerical control devices.

[0027] It should be noted that the limiting rod 212 and the first bonding block 213 provided on the fixed motor 21 are mainly used to limit the brake pad 13 on the clamping table 2, and the brake pad 13 here is in the correct direction, so the bonding limiting function of the brake pad 13 can be completed.

[0028] Furthermore, the limiting rod 212 is L-shaped as a whole, and its long end is arranged perpendicular to the clamping platform 2, which can help to improve the restriction of the holes on both sides of the brake pad 13, thereby improving the matching degree between the brake pad 13 and the limiting rod 212. The limiting rod 212 is made of aluminum alloy as a whole, which has the characteristics of wear resistance and light weight, and can effectively extend the service life of the limiting rod 212. The connection method between the fixed motor 21 and the limiting rod 212 is the first rotating shaft 211, which is made of aluminum alloy material in the prior art, and its two ends are connected to the fixed motors 21 on both sides of the clamping platform 2, and the rotation effect is implemented. The bottom end of the limiting rod 212 is fixedly connected to the first rotating shaft 211, which can improve the synchronization of rotation; Furthermore, the first fitting block 213 is mainly used to fit tightly against one end of the brake pad 13, and this end is located between the two holes, and the brake pad 13 is curved here, and the front end of the first fitting block 213 is set as a curved surface. Under the premise of matching the same as the limiting rod 212, the brake pad 13 can achieve complete fit between the curved surface of this end of the brake pad 13 and the curved surface of the first fitting block 213. The first fitting block 213 is made of wear-resistant material, and the curved surface at one end is provided with a protruding block to increase friction, which can effectively improve the control of the brake pad 13. The first rotating shaft 211 can realize the simultaneous rotation of the limiting rod 212 and the first fitting block 213, thereby achieving the guiding and supporting function of the brake pad 13. Furthermore, an additional output end is provided on the left side of the fixed motor 21 , and a second rotating shaft 214 is provided on the output end. The additional output end is fixedly connected to the first rotating shaft 211 , thereby completing synchronous movement.

[0029] Reference Figure 4 and Figure 5 , the side baffles 22 are arranged on both sides of the clamping platform 2, and their main function is to limit the brake pad 13 from entering the clamping platform 2, maintain the tight effect with the first fitting block 213 and the limiting rod 212, and clamp the two sides of the brake pad 13, so as to improve the stability of the brake pad 13 on the clamping platform 2, and on the inner side of each side baffle 22, an aluminum alloy rod 221 for assisting in lifting the brake pad 13 is arranged, the aluminum alloy rod 221 is vertically arranged on the side of the side baffle 22, and is flush with the rear end of the fixed motor 21, and a resisting rod 222 for reducing the friction force generated with the side baffle 22 is provided on the aluminum alloy rod 221, and secondly, as the contact surface of the aluminum alloy rod 221, the bottom of the brake pad 13 can be quickly held according to the linear arrangement order; Furthermore, the aluminum alloy rod 221 is provided with a plurality of bonding plates 223 for increasing the contact area, and the whole is T-shaped and made of hard plastic material, which has a certain lightness and can increase the service life. The manufacturing cost is low. One side of the bonding plate 223 does not abut against the side baffle 22, and there is a gap between the two to avoid long-term friction between the bonding plate 223 and the side baffle 22 and affect the service life. The other end of the aluminum alloy rod 221 is fixedly connected to the second rotating shaft 214 through an auxiliary connecting rod 224, so that the aluminum alloy rod 221 as a whole can rotate synchronously with the first rotating shaft 211.

[0030] Reference Figure 6 Since the direction of individual brake pads 13 when entering the clamping table 2 is not compatible with the limiting rod 212 and the first bonding block 213, the current brake pad 13 cannot be synchronously flipped with the first rotating axis 211, thereby blocking the entire workflow. The bottom of the side baffle 22 is set to pass through the clamping table 2, mainly for the side baffle 22 to correct the direction of the brake pad 13 without being hindered by the side baffle 22, and complete the direction correction.

[0031] It should be noted that a triggerable retractable trigger rod 225 is provided at the bottom of the side baffle 22, and the trigger rod 225 fixes and connects the two side baffles 22, thereby realizing synchronous retracting movement. The trigger rod 225 is made of aluminum alloy material as a whole.

[0032] Furthermore, a spring shaft 226 is symmetrically provided at the bottom of the trigger rod 225 for improving the contraction effect of the side baffle 22. The spring shaft 226 is a prior art, which is composed of a compression spring and a telescopic shaft. At the same time, the spring shaft 226 has a rebound effect. When the pressure disappears, the side baffle 22 can be reset.

[0033] Reference Figure 4 and Figure 5 A rotating disk 23 for supporting and rotating the brake pad 13 is provided on the clamping table 2. The rotating disk 23 is circular as a whole and is arranged in front of the first bonding block 213. A gravity sensor 24 for sensing the brake pad 13 is provided above the rotating disk 23. The rotation of the rotating disk 23 is mainly realized based on the gravity sensing and triggering structure. When the brake pad 13 is located above the rotating disk 23 in the correct direction, the rotating disk 23 will not rotate.

[0034] Reference Figure 6 , Fig.11 and Fig.12 An auxiliary table surface for connecting to the clamping table 2 is provided under the rotating disk 23, and a supporting cylinder 233 for rotation is provided at the bottom of the rotating disk 23, and the interior of the supporting cylinder 233 is in a through state, and a built-in screw 2331 is provided on the inner wall of the half side, and the built-in screw 2331 is spirally arranged upward, and the built-in screw 2331 is generally facing the direction of the conveying platform, and a main rotating component, namely, a lifting shaft 2332, is provided inside the supporting cylinder 233. The lifting shaft 2332 is driven by electricity to achieve the rotation effect, and at the same time, an external thread 2333 is provided on the side wall of the lifting shaft 2332, which can engage with the built-in screw 2331 during rotation, and follow the route and direction of the built-in screw 2331 to change the current height of the lifting shaft 2332, thereby achieving the lifting effect of the rotating disk 23.

[0035] Furthermore, a driving rod 232 capable of driving the lifting shaft 2332 is provided at the bottom of the clamping table 2, and an external motor is provided inside the driving rod 232, and the switch of the external motor is arranged at the other end of the driving rod 232 by changing the wiring of the wires, and the output end of the external motor is fixedly connected to the lifting shaft 2332 through the wires, thereby realizing the rotation effect of the rotating disk 23, and the driving rod 232 is fixedly connected to the clamping table 2 through the auxiliary rod 231 arranged at the bottom, ensuring that the driving rod 232 maintains stability during operation, and at the same time, the driving rod 232 is in an overhead state, which can be beneficial to the heat dissipation effect of the external motor.

[0036] Refer to 5 and Figure 6A first peripheral motor 25 is provided on one side of the clamping platform 2. Here, a booster rod 251 for pushing the brake pad 13 is provided on the first peripheral motor 25. The function of the booster rod 251 is to prevent the brake pad 13 from entering the clamping platform 2 and causing a height difference so that it cannot fall correctly onto the rotating disk 23, thereby preventing it from completing the flipping effect. When the front end of the brake pad 13 abuts against the surface of the clamping platform 2, the rear end is suspended on the first conveyor belt 11. At this time, the brake pad 13 can be pushed forward by the booster rod 251 through the drive of the first peripheral motor 25 to ensure that the brake pad 13 is located above the gravity sensor 24.

[0037] It should be noted that the first external motor 25 is fixed to the other end of the clamping platform 2 by a fastener, and the booster rod 251 is arranged below the first conveyor belt 11 , and the normal unloading process of the brake pad 13 will not affect the normal use of the booster rod 251 .

[0038] Furthermore, second external motors 26 for fitting the rear end of the brake pad 13 are provided on both sides of the first external motor 25, and an auxiliary telescopic strip is provided on the second external motor 26. The auxiliary telescopic strip is mainly composed of multiple groups of connecting rods and frames. The connecting rods and frames are made of aluminum alloy and can be adjusted in limited length on the clamping table 2. The auxiliary telescopic strip is provided with a second fitting block 262 for fitting the rear end of the brake pad 13. Since the rear end of the brake pad 13 is a curved surface, the two symmetrically arranged second fitting blocks 262 are both provided with arc surfaces that conform to the curved surface of its rear end, thereby restricting the correctly positioned brake pad 13.

[0039] Furthermore, in order to prevent the brake pad 13 on the first conveyor belt 11 from being affected by the second bonding block 262 and reducing the efficiency of entering the clamping table 2, the second bonding block 262 can be flipped 90° by the third rotating shaft 261 set on the auxiliary telescopic strip, and the flip is toward the rotating disk 23. The second peripheral motor 26 is equipped with a CNC component in the prior art, which can be combined with the first conveyor belt 11 and the driving rod 232 of the rotating disk 23 through CNC instructions to avoid the rotation of the brake pad 13 and the collision of entry.

[0040] Reference Figure 4 The clamping platform 2 is provided with an anti-scratch groove 27 to prevent the rotating disk 23 from scratching it. The anti-scratch groove 27 extends along both sides of the rotating disk 23 and is parallel to the clamping platform 2, and extends outward to prevent the rotating disk 23 from being pressed down and scratched by the clamping platform 2 due to its weight when the rotating disk 23 carries the brake pad 13.

[0041] Reference Figure 4 and Figure 7A first trigger piece 283 for monitoring whether the direction of the brake pad 13 is correct is provided on the clamping platform 2. At the same time, the first trigger piece 283 is fixed to the clamping platform 2 through a support rod 28. The support rod 28 is fixed to the clamping platform 2 by welding. The support rod 28 fixes the first trigger piece 283 through a central rotating member 282, and a fourth rotating axis 284 is provided at both ends of the central rotating member 282, so that the first trigger piece 283 can rotate on the fourth rotating axis 284. At the same time, when the central rotating member 282 floats up and down, a force is generated to cause the first trigger piece 283 to rise or shrink.

[0042] It should be noted that the central rotating member 282 is the main function component of the first trigger piece 283 and the second trigger piece 285 . One end of the second trigger piece 285 is fixedly connected to another fourth rotating shaft 284 and can rotate on the fourth rotating shaft 284 .

[0043] Furthermore, the other end of the driving rod 232 is in a suspended state, and a contact hole 234 for starting the rotating disk 23 is opened on the surface. The contact hole 234 is rectangular, and a starting switch 286 for starting the driving rod 232 is provided at the bottom of the contact hole 234. The starting switch 286 is a common contact electric control component in the prior art, and is used to turn on and off the power supply of the component.

[0044] Furthermore, when there is a brake pad 13 with the correct orientation on the rotating disk 23, when the first trigger piece 283 shrinks downward due to pressure, the second trigger piece 285 produces an upward movement under the force state of the central rotating part 282, and then the second trigger piece 285 leaves the trigger range of the start switch 286. At the same time, the gravity sensor 24 generates a signal due to the pressure of gravity, and the current driving rod 232 does not receive the command of the start switch 286, so the rotating disk 23 will not produce a rotation effect, and when the second trigger piece 285 is lifted, it is placed in the anti-stuck groove 281.

[0045] Furthermore, when the first trigger plate 283 is not subjected to the gravity pressure of the brake pad 13, the first trigger plate 283 produces an upward effect under the influence of the gravity balance of the central rotating member 282, and then the other end of the central rotating member 282 generates downward pressure, causing the second trigger plate 285 to descend and collide with the start switch 286, so that the drive rod 232 triggers the open state, and at the same time, when the gravity sensor 24 transmits the gravity signal, the rotating disk 23 is supported by the rotational power and rotates. When the rotating disk 23 rotates, the fixed motor 21 will receive the transmitted signal and be driven, and then all components on the first rotating shaft 211 will rotate accordingly. When the first bonding block 213 flips forward, it will drive the trigger rod 225 at the bottom of the clamping table 2 and cause the side baffle 22 to shrink downward, leaving enough space for the rotation of the brake pad 13 to improve the rotation efficiency of the brake pad 13.

[0046] Furthermore, the corrected brake pad 13, the limiting rod 212 and the first bonding block 213 will be reset again and abutted against the currently corrected brake pad 13 under the drive of the first rotating shaft 211, and then, driven by the fixed motor 21, the aluminum alloy rod 221, the resisting rod 222 and the bonding plate 223 will lift the bottom of the brake pad 13 and flip the brake pad 13 forward until the brake pad 13 falls onto the grinding table 3.

[0047] Reference Figure 8 and Fig. 9 The grinding table 3 is arranged at one end of the clamping table 2, wherein the grinding table 3 is connected to the clamping table 2 through a second conveyor belt 31. The brake pad 13 will fall accurately onto the second conveyor belt 31 after being flipped over. The second conveyor belt 31 belongs to the prior art. A common transmission roller and a transmission belt are arranged at one end of the grinding table 3, and are driven by an external power supply. They are mainly used to convey the brake pad 13 flipped down from the clamping table 2.

[0048] It should be noted that the grinding table 3 also needs to convey the brake pad 13 to the grinding component, and the brake pad 13 is ground face down, which can effectively prevent the grinding debris from filling up the grinding table 3 and can be collected uniformly later.

[0049] Furthermore, first slide rails 32 are provided on both sides of the grinding table 3. The first slide rails 32 can help the components for conveying the brake pads 13 to maintain uniform and effective sliding. A third peripheral motor 321 is provided on the first slide rail 32. The third peripheral motor 321 is a driving component in the prior art, which drives the components on the grinding table 3 through an external power supply connection. The third peripheral motor 321 is provided with a lifting column 322 that can lower the current height of the brake pads 13. The lifting column 322 is fixed to the top of the third peripheral motor 321 by fasteners, and the whole is provided with a telescopic joint 323. The telescopic joint 323 is composed of a plurality of metal components of the same shape but with a difference in specifications, and a compression spring is provided inside, which can effectively improve the telescopic elasticity of the telescopic joint 323.

[0050] Furthermore, the telescopic joint 323 is provided with an alloy arm 324 for maintaining balanced transportation. The alloy arm 324 is made of alloy material, which can effectively improve the stability of the brake pad 13 during transportation. The alloy arm 324 is provided with a lifting claw 325 for lifting and transporting the brake pad 13. The hollow position in the middle of the lifting claw 325 is used to suspend the polished surface of the brake pad 13 to make the polished surface protrude for later polishing, while the two sides of the brake pad 13 are supported by the lifting claw 325 and moved to the polishable area.

[0051] Reference Figure 8The other end of the grinding table 3 is provided with a grinding block 34 for grinding the brake pad 13. The grinding block 34 is fixed on the grinding table 3 through a driving plate 33. A driving cylindrical rod that can move laterally is provided in the driving plate 33, and the driving plate 33 is driven by an external power supply. The grinding block 34 is a component in the prior art that is made of wear-resistant material as a whole and has a grinding layer on the surface. By driving the cylindrical rod to move laterally, the grinding block 34 can be driven to produce a strong grinding effect on the bottom of the brake pad 13, so that the potholes and particles on the surface of the brake pad 13 are smoothed, thereby improving the effect of reusing the brake pad 13.

[0052] It should be noted that two detectors are provided on the grinding table 3 for detecting whether the contact surface of the brake pad 13 is horizontal. The detector is an infrared detector in the prior art. It scans the horizontality of the contact surface of the brake pad 13 and transmits data and instructions to the grinding block 34. The brake pad contact surface is ground by the grinding block 34, thereby completing the grinding process of the uneven contact surface of the brake pad 13.

[0053] Reference Fig.10 A transfer platform 4 for transferring the brake pad 13 is provided at one end of the grinding table 3. First slide rails 32 are provided on both sides of the transfer platform 4, and the sliding distance of the alloy arm 324 can be effectively extended to facilitate the brake pad 13 to abut against the transfer platform 4.

[0054] It should be noted that the transfer platform 4 is only used to transfer the polished brake pad 13, and one end of the transfer platform 4 is provided with a slope platform 41 for the brake pad 13 to slide down by itself, the slope platform 41 is opened at 45 degrees, and the middle area of ​​the transfer platform 4 is provided with a second slide rail 42, so that the transfer brake pad 13 component can have a shorter distance, so that it can complete the work of transferring the brake pad 13, and the second slide rail 42 is provided with a mechanical arm 43, which is a prior art, made of aluminum alloy material, and can be used for bearing and grasping work in various fields, and the mechanical arm 43 is provided with a second slide rail 42. A lifting plate 44 is provided for carrying the polished rear brake pad 13. The lifting plate 44 is fixedly connected to the mechanical arm 43 by fasteners. The fasteners are square aluminum alloy components. After the connecting ends of the two are spliced, they are fixed by bolts. Then the brake pad 13 is transferred to the slope platform 41. A fourth peripheral motor 45 is provided on one side of the transfer platform 4 for driving the mechanical arm 43 to move on the second slide rail 42, and the mechanical arm 43 is connected to the output end of the fourth peripheral motor 45 through an auxiliary line. The auxiliary line is the electric wire used for power transmission in the prior art.

[0055] The working principle of the present invention is as follows: S1. First, the first conveyor belt 11 will transfer the brake pad 13 to be polished to the conveyor platform 1, and then the first slider 14 on the conveyor platform 1 will automatically focus on the brake pad 13. The telescopic rod 15, the first fixed end 16 and the second fixed end 17 on the first slider 14 will limit the brake pad 13, and all components will be locked by adjusting the screw 18 to make it firmly on the first conveyor belt 11, and the first slider 14 will keep the brake pad 13 in the correct direction of transportation under the movement of the first conveyor belt 11, and then transport the brake pad 13 to the clamping platform 2.

[0056] S2, the brake pad 13 enters the clamping table 2. When the two holes on the brake pad 13 face forward, the second peripheral motor 26 will receive a flipping instruction, and the third rotating shaft 261 will flip the second fitting block 262 downward, leaving a larger space for the brake pad 13 to enter. Then, after the brake pad 13 enters the clamping table 2, the first peripheral motor 25 will start to move the booster rod 251 forward to prevent the brake pad 13 from standing between the clamping table 2 and the conveying table 1 due to the height difference. While the booster rod 251 pushes the brake pad 13, the brake pad 13 will be restricted due to the structural characteristics of the clamping table 2. Finally, the holes on both sides of the brake pad 13 will abut against the limiting rod 212, and the front end of the brake pad 13 will abut against the first fitting block 213, and the brake pad 13 will abut against the rotating disk 23 and the first trigger plate 283. At this time, the rotating disk 23 will not rotate due to the gravity sensor of the brake pad 13.

[0057] S3. When the two holes opened on the current brake pad 13 are facing backward, the second peripheral motor 26 will receive a flipping instruction, and the third rotating shaft 261 will flip downward with the second fitting block 262, leaving a larger space for the brake pad 13 to enter. Then, after the brake pad 13 enters the clamping table 2, the first peripheral motor 25 will be started to move the booster rod 251 forward to prevent the brake pad 13 from standing between the clamping table 2 and the fish conveying table 1 due to the height difference. While the booster rod 251 pushes the brake pad 13, the brake pad 13 will be restricted due to the structural characteristics of the clamping table 2. Since the brake pad 13 is in the wrong direction, the gravity sensor 24 will be under pressure, and the first trigger plate 283 will lose the counteracting force and lift upward under the action of the loss of balance of the central rotating member 282. The second trigger plate 285 at the other end of the central rotating member 282 will impact the starting switch 286 downward, so that the power drive of the driving rod 232 is turned on, and then the rotating disk 23 starts to rotate.

[0058] S4. Before the rotating disk 23 rotates, the fixed motor 21 receives a driving instruction, and then the first rotating shaft 211 drives the limiting rod 212 and the first bonding block 213 to flip forward, thereby freeing up space for the rotation radius of the brake pad 13. When the first bonding block 213 rotates downward, it touches the trigger rod 225 at the bottom of the side baffle 22. The trigger rod 225, on the basis of being against the grinding table 3, enables the side baffle 22 to achieve a downward and contracting action, and is hidden under the clamping table 2, so as to increase the space for the rotation radius of the brake pad 13.

[0059] S5. When the brake pad 13 rotates to 90° on the rotating disk 23, the lifting shaft 2332 in the support tube 233 rotates, and the external thread 2333 on its surface will overlap with the internal screw 2331 in the support tube 233, and drive the lifting shaft 2332 to lift upward, so that the rotating disk 23 is lifted upward as a whole, avoiding the brake pad 13 on the rotating disk 23 from contacting the first trigger plate 283 in the lifted state, causing it to be pressed down and disconnect the rotating disk 23. Driven by electricity, when it rotates to 135°, the external thread 2333 and the internal screw 2331 are disengaged, and the lifting shaft 2332 falls at this moment and stops rotating after rotating 180°. Then the motor 21 is fixed to drive the first rotating shaft 211 again, so that the limiting rod 212 and the first bonding block 213 limit the brake pad 13, and then the brake pad 13 is flipped out of the clamping table 2 together with the aluminum alloy rod 221, and placed on the second conveyor belt 31 on the grinding table 3.

[0060] S6, after the brake pad 13 falls onto the second conveyor belt 31, it is scanned according to the detectors on both sides of the grinding table 3 to scan whether the current contact surface of the brake pad 13 is in a horizontal state. When the contact surface of the brake pad 13 does not meet the monitoring result of the detector, it will slide on the first slide rail 32 with the assistance of the slider of the third peripheral motor 321, and the lifting claw 325 gradually becomes lower than the horizontal height of the second conveyor belt 31 under the height adjustment function of the telescopic joint 323, so that the lifting claw 325 can receive the brake pad 13 at the end of the second conveyor belt 31. Then, after the brake pad 13 falls into the lifting claw 325, it gradually becomes lower than the second conveyor belt 31 under the adjustment of the telescopic joint 323, and then stops above the grinding block 34 driven by the third peripheral motor 321. Then, driven by the driving plate 33, the grinding block 34 grinds the bottom of the brake pad 13, and the grinding debris also falls off; When the monitoring result of the detector meets the requirements, the brake pad 13 leaves the grinding table 3 and enters the transfer table 4 with the assistance of the lifting claw 325 and the slider.

[0061] S7. The polished brake pad 13 will move forward again under the support of the lifting claws 325, and the third peripheral motor 321 will move to the transfer table 4 and stop above the lifting plate 44. Then, the distance between the lifting claws 325 will be expanded under the adjustment of the alloy arm 324, and the brake pad 13 will fall onto the lifting plate 44. The mechanical arm 43 on the transfer table 4, driven by the fourth peripheral motor 45, will shake the brake pad 13 onto the lifting plate 44 through a short impact effect and slide off the slope platform 41.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
