[0013] Please see Figures 1 to 8 The brake pad grinding equipment provided in this embodiment includes: a robot 10 and a brake pad grinding platform; The brake pad grinding platform is equipped with a milling device 20, a measuring device 30 and a linear moving slide 40. The linear moving slide 40 reciprocates between the milling device 20 and the measuring device 30 according to the instructions of the control system. A fixture storage platform for temporarily storing brake pad fixtures 50 is provided on one side of the brake pad grinding platform, and a pneumatic suction cup 60 is provided on the other side of the brake pad grinding platform. The robot 10 has brake pad trays 70 on both sides. The working area of ​​the robot 10 covers the fixture storage platform, brake pad trays 70, pneumatic suction cups 60 and linear moving slides 40. The robot 10's operating end, linear moving slides 40 and fixture storage platform are equipped with quick-change device main plates, and the brake pad fixtures 50 and pneumatic suction cups 60 are equipped with quick-change device auxiliary plates.

[0014] In practice: The brake pad grinding equipment achieves automatic measurement and grinding of brake pads. Before grinding, the maximum and minimum height values ​​of the brake pad surface are measured by the measuring device 30. The control system determines the milling amount required for grinding. Then, the milling device 20 grinds the brake pad surface. After grinding, the measuring device 30 measures again. If the height difference between the maximum and minimum height values ​​of the brake pad after milling does not meet the brake pad grinding process standard, the brake pad is ground again until the height difference between the maximum and minimum height values ​​meets the brake pad grinding process standard. Furthermore, a dedicated workspace is provided for the brake pad grinding equipment.

[0015] The brake pad grinding equipment includes a robot 10, a brake pad grinding platform and a brake pad tray 70. The brake pad grinding platform is equipped with a milling device 20, a linear moving slide 40, a jig storage platform, a measuring device 30 and a pneumatic suction cup 60.

[0016] Robot 10 is fixed to the ground. Its operating end is equipped with a quick-change device main plate, which allows movement of the brake pad fixture 50. The quick-change device main plate can also quickly dock with the pneumatic suction cup 60 to adsorb brake pads and mount them onto the brake pad fixture 50, completing the loading and unloading of brake pads. The working area of ​​robot 10 covers the milling device 20, linear motion slide 40, brake pad fixture 50, fixture storage platform, measuring device 30, and pneumatic suction cup 60.

[0017] Brake pad trays 70 are placed on both sides of robot 10 and are used to store brake pads, including brake pad trays to be processed and qualified brake pad trays.

The linear laser emitter 32 projects a laser line onto the surface of the brake pad to be repaired. The protrusions and depressions on the surface of the brake pad will distort the linear laser. The industrial camera 33 captures the distorted laser line modulated by the surface of the brake pad at a specific angle, forming laser image information and establishing the thickness information of the brake pad at the position of this laser line. The linear moving slide 40 drives the brake pad to move relative to the measuring device 30, completing the acquisition of the thickness information of the entire brake pad surface, establishing the contour data of the entire brake pad, and obtaining the difference between the maximum and minimum thickness values ​​of the brake pad. The control system calculates the milling amount of the brake pad to be processed based on the brake pad grinding process standard value, the maximum height value, and the minimum height value. The determined milling amount is sent to the milling device 20, which then mills the brake pad according to the milling amount.

[0021] The mounting base 41 of the linear slide table 40 is fixedly mounted on the brake pad grinding platform. The linear slide table 42 is connected to the mounting base 41 via a horizontal guide rail 44. A second ball screw 45 is mounted on the linear slide table 42. A second drive motor 43 is the power output device, and it is fixedly connected to the linear slide table 42. Its output end is connected to the second ball screw.

The first clamp 52 is fixedly connected to the mounting platform 51, and the second clamp 53 is slidably connected to the mounting platform 51 via a guide rod 56. The first clamp 52 and the second clamp 53 are both provided with fixing grooves that are adapted to the dovetail groove of the brake pad on opposite sides to lock the brake pad, so that the brake pad and the brake pad fixture 50 form a stable and firm whole.

The main quick-change device on the linear slide 40 locks with the auxiliary quick-change device on the brake pad fixture 50. When the main and auxiliary quick-change devices of Robot 10 are released, the main quick-change device engages with the auxiliary quick-change device on the pneumatic suction cup 60, adsorbing and placing the brake pad into the dovetail groove of the brake pad fixture 50.
