[0030] As Figure 1-3 shown, the sandpaper tearing module 3 includes a bearing platform 31 for placing the grinding head for sandpaper replacement. Scrap collection areas 32 are arranged on both sides of the bearing platform 31 in the width direction for receiving the old sandpaper torn from the grinding head. Preferably, both the bearing platform and the accommodating space are located on an annular track with the rotating cylinder as the center and the length from the end of the feeding plate equipped with the vacuum chuck to the end connected to the rotating cylinder as the radius, so as to ensure the feeding accuracy of the feeding plate.

The transverse driving member 34 is connected to the placement plate 35, and the placement plate 35 is driven to slide by the transverse driving member 34. The two clamping assemblies are correspondingly placed on the placement plate 35, and the two clamping assemblies are driven to slide synchronously by the sliding of the placement plate 35 to ensure that the two clamping assemblies move synchronously. The transverse sliding rail 33 extends from the side of the bearing platform 31 to the side of the waste collection area 32, ensuring that the clamping assembly can reciprocally slide between one side of the bearing platform 31 and one side of the waste collection area 32 to complete the transfer of the old sandpaper. The clamping assembly clamps the old sandpaper on the grinding head at the bearing platform 31 and moves to the waste collection area 32 to place the old sandpaper in the waste collection area 32. Preferably, there are two sets of transverse sliding rails 33, which are respectively arranged on both sides of the bearing platform 31 along the width direction, and both ends of the placement plate 35 are slidably arranged on the two sets of transverse sliding rails 33 to improve the stability of the placement plate 35 during the transverse movement. Preferably, in this embodiment, the transverse driving member 34 can be a cylinder, a motor screw module, etc., and no specific limitation is made here.

[0033] As Figure 1-3 shown in the figure, the clamping assembly includes a first lifting cylinder 36 arranged on the placement plate 35.

The first lifting cylinder 36 drives the clamping cylinder 38 to continue rising, and the old sandpaper detaches from the grinding head 42. The transverse movement driving member 34 drives the clamping assembly and the clamped old sandpaper to move above the waste collection area 32. The clamping cylinder 38 releases the old sandpaper, and the old sandpaper falls into the waste collection area 32. The telescopic cylinder 37 drives the clamping cylinder 38 to retract to the side away from the bearing platform, providing an avoidance space for the robotic arm to leave.

[0038] Meanwhile, the rotary cylinder 23 drives the feeding plate 24 to rotate, so that the vacuum suction cup 25 rotates above the accommodating area. The second lifting cylinder 22 drives the feeding plate 24 to descend, and the vacuum suction cup 25 sucks up the new sandpaper 5 in the accommodating area. The second lifting cylinder 22 drives the feeding plate 24 to rise, driving the new sandpaper to rise synchronously. The rotary cylinder then drives the feeding plate 24 to rotate, so that the vacuum suction cup 25 rotates above the bearing platform 31. The second lifting cylinder 22 drives the feeding plate 24 to descend, and the vacuum suction cup 25 adheres the new sandpaper to the grinding head 42, thus completing the sandpaper replacement.
