[0039] Working principle: turn two clamping plates 413, place the workpiece 5 to be pasted on the static skin 34, so that the workpiece 5 to be pasted is clamped by two clamping plates 413, when the back glue is pasted on one side and needs to be rotated, step on the pedal 22, so that the first guide wire 23 is pulled, the sliding rod 24 is driven to slide, the torsional spring piece 271 is moved, the limiting plate 272 is moved, and the limiting plate 272 is respectively combined with the inclined tooth 29 to bear stress.

By setting the length of the sliding rod 24, the rotating disc 28 rotates about ninety degrees each time, the bearing 31 rotates, the mounting shell 32 rotates, the work plate 33 rotates, the static skin 34 rotates, and the workpiece to be pasted rotates. The mounting shell 32 rotates to drive the clamping assembly 4 to rotate, so that the two clamping plates 413 rotate synchronously. Through the clamping of the two clamping plates 413 on the workpiece 5 to be pasted, the position of the workpiece 5 to be pasted is prevented from deviating during rotation;

[0040] When the mounting shell 32 rotates, the third spring expansion piece 35 rotates, the first circular arc block 36 rotates, the first circular arc block 36 moves out of one limiting groove 11, and the third spring expansion piece 35 contracts.

At this time, the back glue can be pasted again;

[0041] When the pedal 22 is no longer stepped on, the first spring expansion piece 26 releases, drives the sliding rod 24 to move, and the inclined tooth piece 27 moves. At this time, the inclined block 273 cannot support the limiting plate 272, so that the limiting plate 272 rotates after encountering the inclined tooth 29, so that the movement of the inclined tooth piece 27 does not drive the rotating disc 28 to rotate. At the same time, the sliding rod 24 moves to drive the first guide wire 23 to be pulled, so that the pedal 22 is pulled back to reset, so that the driving assembly 2 is reset for the next rotation of the workpiece 5 to be pasted;

[0042] When the installation shell 32 rotates to drive the fourth spring telescopic piece 41 to move, the abutting block 42 moves to drive the second circular arc block 43 to rotate, when the second circular arc block 43 rotates into the clamping groove, the fourth spring telescopic piece 41 is released, the abutting block 42 moves to drive the two abutting pieces 45 to move, the two fifth spring telescopic pieces 44 are retracted to make the two second guide wires 46 relax, the rotating shaft 47 can rotate, the four sixth spring telescopic pieces 412 are released to drive the sliding plate 410 to move, the two third guide wires 48 are pulled to drive the rotating shaft 47 to rotate, the workpiece 5 to be pasted is released from clamping, at this time, the workpiece 5 to be pasted is pasted on four sides with back glue, the workpiece 5 to be pasted can be taken down, then the pedal 22 is stepped on to make the installation shell 32 rotate, the device as a whole is reset to facilitate pasting back glue on the next workpiece 5 to be pasted.

[0043] The above only describes certain exemplary embodiments of the present application in a manner of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art.
