Example 2

[0020] A power pusher is provided on the top of the tray 5 for cooperating with the switching clamping mechanism to switch the clamping position of the brake pad 16. The power pusher includes a rectangular rod 31 slidably connected to the inner side of the connecting seat 18, one end of the rectangular rod 31 penetrates through the inner side of the connecting seat 18 and is fixedly connected with a concave ring 19, one end of the concave ring 19 is fixedly connected with an inclined block 20, the other end of the rectangular rod 31 penetrates through the outside of the connecting seat 18 and is fixedly connected with a second spherical rod 30, a power spring 32 is installed between the second spherical rod 30 and the connecting seat 18, and one end of the auxiliary frame 9 is provided with an inclined surface 40; Four sliding rods 22 are provided, one of which is located at the lowest point of the disc 17 and initially always abuts against the bottom of a clamping block 15 through the rotating wheel 35, so that the clamping block 15 at the bottom of the concave ring 19 will never rotate during the movement. When the brake pad 16 is placed on the top of the clamping block 15, the tray 5 is driven by the chain 4 to drive the second spherical rod 30 to move toward the auxiliary frame 9. When the second spherical rod 30 contacts the inclined surface 40, the inclined surface 40 drives the second spherical rod 30 to drive the concave ring 19 to move toward the first spherical rod 21, thereby pushing the three first spherical rods 21 to drive one sliding rod 22 to move toward the rotating block 36, thereby respectively pushing the clamping blocks 15 on both sides to rotate toward the brake pad 16.

When the chain 4 drops slightly, the roller 33 contacts the slope at the end of the guide rail groove during the movement of the pallet 5. The position of the pallet 5 can be calibrated under the action of the slope, thereby ensuring the accuracy of the brake pad 16 when it is transported to the designated location for testing.

[0022] Working principle: A driving motor for driving the rotating roller 2 to rotate is installed on one side of the support 1. When the brake pad 16 needs to be inspected for convex points, the staff can place the brake pad 16 on the clamping block 15 manually or by a robot, and then start the driving motor. The driving motor drives the rotating roller 2 to drive the first straight gear 3 to rotate, and then drives multiple brake pads 16 to be fed and inspected through the chain 4. The guide pipe 8 can be connected with the external fluorescent paint supply pipe, so that the external supply pipe can supply the fluorescent paint into the paint tube 12 through the guide pipe 8 and the inside of the guide shell 11. When there is a convex point on the brake pad 16, it contacts the ball 13, and the fluorescent paint is applied to the convex point through the rolling of the ball 13, and then Then it enters the fluorescence detection machine 6 for fluorescence detection. When the first surface detection of the brake pad 16 is completed, the brake pad 16 continues to move under the drive of the chain 4, and the connecting seat 18 contacts the second spur gear 29. Under the drive of the connecting seat 18, the second spur gear 29 drives the worm 26 to rotate, and then drives the worm wheel 25 to drive the disc 17 to rotate through the rotating shaft 24. When the connecting seat 18 is separated from the second spur gear 29, the disc 17 drives the brake pad 16 to rotate ninety degrees, so that the side of the brake pad 16 contacts another group of balls 13, so as to perform fluorescence detection again. Through the four groups of fluorescence detection machines 6 and four connecting seats 18 arranged in sequence, the brake pad 16 can be intermittently rotated. When the disc 17 rotates in a circle, when the first spherical rod 21 on the side rotates to the top and separates from the concave ring 19, the connecting spring 23 pushes the first spherical rod 21 to reset, so that the clamping block 15 rotated to the top is no longer reset by external force, and the first spherical rod 21 rotated from the top to the side contacts the inclined block 20 during the movement, and the inclined block 20 pushes the first spherical rod 21 to move toward the rotating block 36, so that the originally opened rotating block 36 can be clamped on the side of the brake pad 16 under the action of the sliding rod 22, and the position switching of the clamping block 15 at the part of the brake pad 16 that needs to be detected is realized by reciprocating; Four sliding rods 22 are provided, one of which is located at the lowest point of the disc 17 and initially always abuts against the bottom of a clamping block 15 through the rotating wheel 35, so that the clamping block 15 at the bottom of the concave ring 19 will never rotate during the movement. When the brake pad 16 is placed on the top of the clamping block 15, the tray 5 is driven by the chain 4 to drive the second spherical rod 30 to move toward the auxiliary frame 9. When the second spherical rod 30 contacts the inclined surface 40, the inclined surface 40 drives the second spherical rod 30 to drive the concave ring 19 to move toward the first spherical rod 21, thereby pushing the three first spherical rods 21 to drive one sliding rod 22 to move toward the rotating block 36, thereby respectively pushing the clamping blocks 15 on both sides to rotate toward the brake pad 16. When the concave ring 19 stops moving, the brake pad 16 is clamped by the clamping blocks 15 on both sides. When the pallet 5 moves toward the auxiliary frame 9, the roller 33 enters the guide rail groove to provide support for the pallet 5. When the chain 4 falls slightly, the roller 33 contacts the slope at the end of the guide rail groove during the movement of the pallet 5, and the position of the pallet 5 can be calibrated under the action of the slope.
