[0037] Preferably, the clamping assembly 4 includes two fifth spring telescopic members 44 arranged in the mounting shell 32, and an abutment member 45 is respectively arranged on the output end of the two fifth spring telescopic members 44, and the two abutment members 45 correspond to the position of the abutment block 42, and one end of two second wires 46 are respectively connected to the two abutment members 45 in a one-to-one correspondence, and the other ends of the two second wires 46 are connected to a rotating shaft 47, and the rotating shaft 47 is rotatably connected to the working plate 33, and one end of two third wires 48 are connected to the rotating shaft 47, and the other ends of the two third wires 48 both pass through the outside of the mounting shell 32.

[0038] Preferably, one end of the two third wires 48 located outside the mounting shell 32 passes through the two limit frames 49 respectively, and the two limit frames 49 are fixedly connected to the workpiece board 33. One end of the two third wires 48 passing through the limit frames 49 is connected to the two sliding plates 410 one by one, and the two sliding plates 410 slide in the two limit frames 49 one by one. A fixed plate 411 is provided on each of the two sliding plates 410, and two sixth spring expansion members 412 are provided on each of the two fixed plates 411. A clamping plate 413 is provided at the output end of the two sixth spring telescopic members 412, and the two clamping plates 413 correspond to the positions on both sides of a CG plate 51 respectively. The cooperation between the second arc block 43 and the clamping groove enables the fourth side of the workpiece 5 to be pasted to be glued when the workpiece 5 to be pasted is rotated 270 degrees. At this time, the clamping assembly 4 releases the clamping of the workpiece 5 to be pasted to facilitate the removal of the workpiece 5 to be pasted, and after the mounting shell 32 is rotated 360 degrees, the device can be reset for the next glue pasting.

[0039] Working principle: Move the two clamping plates 413 to place the workpiece 5 to be pasted on the electrostatic leather 34, so that the workpiece 5 to be pasted is clamped by the two clamping plates 413. When the adhesive is pasted on one side and the workpiece 5 to be pasted needs to be rotated, the pedal 22 is stepped on to pull the first wire 23, drive the sliding rod 24 to slide, so that the two torsion springs 271 move, drive the limit plate 272 to move, so that the limit plates 272 are respectively in contact with the bevel teeth 29 to bear force, and the bevel block 273 is set so that the limit plate 272 can drive the bevel teeth 29 to move. The teeth 29 move so that the turntable 28 can rotate. By setting the length of the sliding rod 24, the turntable 28 rotates about ninety degrees each time, driving the bearing 31 to rotate, so that the mounting shell 32 rotates, driving the working plate 33 to rotate, so that the electrostatic skin 34 rotates, and drives the workpiece to be attached to rotate. When the mounting shell 32 rotates, it drives the clamping assembly 4 to rotate, so that the two clamping plates 413 rotate synchronously. The two clamping plates 413 clamp the workpiece 5 to be attached to prevent the workpiece 5 from shifting when it rotates.

[0040] When the mounting shell 32 rotates, it drives the third spring expansion member 35 to rotate, so that the first arc block 36 rotates, drives the first arc block 36 to move out of one limiting groove 11, and makes the third spring expansion member 35 contract. When the first arc block 36 moves into the other limiting groove 11, the third spring expansion member 35 is released, drives the first arc block 36 to enter the limiting groove 11, and at the same time, when the rotating disk 28 rotates, it drives the abutment plate 210 to rotate, so that the second spring expansion member 211 is compressed. When the baffle plate is no longer in contact with the second spring expansion member 211, the second spring expansion member 211 is released, so that the second spring expansion member 211 abuts against the next abutment plate 210, and the rotating disk 28 is limited by the limit between the first arc block 36 and the clamping groove, so that the workpiece 5 to be attached completes the limit after rotating ninety degrees, and the back glue can be attached again at this time;

[0041] When the pedal 22 is no longer stepped on, the first spring expansion member 26 is released, driving the sliding rod 24 to move, so that the helical gear member 27 moves. At this time, the inclined block 273 cannot support the limit plate 272, so that the limit plate 272 will rotate after encountering the helical teeth 29, so that the movement of the helical gear member 27 will not drive the rotation of the turntable 28. At the same time, the movement of the sliding rod 24 drives the first wire 23 to be pulled, so that the pedal 22 is pulled to reset, so that the driving assembly 2 is reset to facilitate the next rotation of the workpiece 5 to be attached;

[0042] When the mounting shell 32 rotates, the fourth spring telescopic member 41 is driven to move, so that the abutment block 42 moves, and the second arc block 43 is driven to rotate. When the second arc block 43 rotates into the clamping groove, the fourth spring telescopic member 41 is released, driving the abutment block 42 to move, so that the two abutment members 45 move, driving the two fifth spring telescopic members 44 to contract, so that the two second wires 46 are relaxed, so that the rotating shaft 47 can rotate, so that the four sixth spring telescopic members 412 are released, and the sliding plate 410 is driven to move, so that the two third wires 48 are pulled, and the rotating shaft 47 is driven to rotate, so that the workpiece 5 to be attached is released from the clamping. At this time, the four sides of the workpiece 5 to be attached are all affixed with adhesive, and the workpiece 5 to be attached can be removed. Then, the pedal 22 is stepped on to rotate the mounting shell 32, so that the device is reset as a whole, so as to facilitate the affixing of adhesive to the next workpiece 5 to be attached.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
