[0036] Further refinement of the embodiment scheme of the present application is shown in Figure 1 and Figure 2As shown, the clamping and overturning assembly includes fixing rods 34, second telescopic pieces 35, a second servo motor 36 and an arc-shaped clamping plate 37, the fixing rods 34 are symmetrically arranged on the mounting plate 33, the second telescopic pieces 35 are symmetrically arranged on the fixing rods 34, the second telescopic pieces 35 are connected with the second servo motor 36, and the second servo motor 36 is connected with the arc-shaped clamping plate 37, and further optimization of the scheme, a rubber layer is arranged on the arc-shaped clamping plate 37 to avoid abrasion of the surface of the steel back of the brake pad during clamping.

[0037] It should be noted that the three-axis device 11, the vacuum pump 21, the first telescopic piece 31, the first servo motor 32, the second telescopic piece 35 and the second servo motor 36 are electrically connected with a controller, which is not shown in the figure.

[0038] The working process of the utility model is as follows:

[0039] Firstly, the controller controls the three-axis device to move to find a position, so that the suction cup 23 moves to the upper side of the neatly stacked brake pad steel back (the brake pad steel back stacking area is pre-planned), then the suction cup 23 is lowered and the vacuum pump 21 is worked, so that a brake pad steel back can be adsorbed, then the three-axis device moves according to the pre-set program trajectory, so that the brake pad steel back can be accurately placed in the processing area to complete the feeding, then the device is away from the processing area and does not interfere with the processing process, after the brake pad steel back is processed, the following two situations exist:

[0040] (1) When the brake pad steel back does not need to be turned over, the three-axis device cooperates with the vacuum adsorption assembly to adsorb it again and move away from the processing area, and when it moves to the specified area for unloading, the automatic feeding process of the next brake pad steel back can be started;

[0041] (2) When the brake pad steel back needs to be turned over, the three-axis device cooperates with the vacuum adsorption assembly to adsorb it again and returns to the original route away from the processing area, then the controller first controls the first telescopic piece 31 to work according to the pre-set program, so that the mounting plate 33 moves downward, when the mounting plate 33 moves downward, the first servo motor 32 works, so that the position of the mounting plate 33 moves to the position shown in the description, Figure 2 At this time, the three-axis device does not move and the brake pad steel back is firmly adsorbed on the suction cup 23;

[0042] Then the controller controls the first telescopic part 31 to retract first to make the clamping and overturning assembly move up, and when the brake pad steel back is just between the clamping and overturning assembly, the first telescopic part 31 stops moving (the movement range is calculated in advance), then the brake pad steel back is clamped by the clamping and overturning assembly, and after clamping, the vacuum adsorption is released first, then the first telescopic part 31 moves downward to make the brake pad steel back away from the suction cup 23 to a height not affecting overturning (the movement range is also calculated in advance), then the clamping and overturning assembly works to drive the brake pad steel back to overturn 180 degrees, and after overturning, the first telescopic part 31 drives the brake pad steel back to rise again to contact the suction cup 23 and be adsorbed again, and finally the clamping is released;

[0043] Then the above process is repeated to transport the brake pad steel back to the machining area and automatically feed, then the other side of the brake pad steel back can be machined, after machining, the three-axis equipment cooperates with the vacuum adsorption assembly to adsorb the brake pad steel back again and move forward to complete the unloading process, and after unloading, the automatic feeding process of the next brake pad steel back can be started:

[0044] Compared with the prior art, the device can automatically complete the feeding and unloading processes before and after the machining process of the brake pad steel back, and can automatically turn over the brake pad steel back according to some machining needs, so that the automation degree is significantly improved, and then the labor does not need to operate near the machining area, so that the labor intensity and the safety hidden danger in the operation process are greatly reduced.
