A rotating disk 23 is rotatably mounted on the middle of the rotating shaft 24. The middle of the rotating disk 23 has multiple driving grooves 232 arranged in a ring array. The outer side of the rotating disk 23 has multiple limiting grooves 231 arranged in a ring array. The top of the rotating disk 23 is fixedly mounted on the inner upper surface of the rotating box 2. A driving disk 22 is provided on one side of the rotating disk 23. A limiting block is fixedly mounted on the middle of the top of the driving disk 22. 222, the limiting block 222 and the limiting groove 231 are used in cooperation with each other. The driving block 221 is fixedly installed on one side of the top of the driving disk 22. The driving block 221 and the driving groove 232 are used in cooperation with each other. The first gear 25 is fixedly installed on the upper part of the rotating shaft 24. Multiple evenly distributed synchronous belts 27 are rotatably installed on the top of the rotating box 2. The second gear 26 is fixedly installed on one side of the top of each of the multiple synchronous belts 27. The multiple second gears 26 mesh with the first gear 25. The rotating plate 3 is fixedly installed on the top of the other side of the multiple synchronous belts 27. Three patch devices 11 are fixedly installed on the top of the base plate 1.
[0019] Each of the multiple rotating plates 3 has three third gears 34 rotatably mounted in the middle. Each of the multiple rotating plates 3 has multiple sets of toothed plates 33 slidably clamped in the middle. Each set of toothed plates 33 meshes with the third gears 34. Each set of toothed plates 33 has a clamping plate 35 fixedly mounted on its top. Each of the multiple rotating plates 3 has three electric push rods 31 at its bottom. Each of the multiple toothed plates 33 has one side of its bottom fixedly mounted on the drive end of the electric push rods 31.
[0020] The drive assembly includes a motor 21, the bottom end of which is fixedly mounted on one side of the top of the base plate 1, and the bottom middle of the drive disk 22 is fixedly mounted on the drive end of the motor 21. By setting the motor 21, the drive disk 22 can be driven to rotate.
[0021] A baffle 28 is fixedly installed at the top of the rotating shaft 24. By setting the baffle 28, the upper part of the rotating box 2 can be blocked, thereby protecting the first gear 25 and the second gear 26 at the top of the rotating box 2.
[0022] The bottom ends of multiple rotating plates 3 are all fixedly mounted with mounting brackets 32, and the bottom ends of multiple electric actuators 31 are all fixedly mounted with the top end of the mounting brackets 32. By setting the mounting brackets 32, the electric actuators 31 can be fixedly installed.
[0023] The middle part of the plurality of rotating plates 3 is provided with a plurality of first sliding grooves 331, and a plurality of tooth plates 33 are slidingly clamped in the first sliding grooves 331. By arranging the first sliding grooves 331, the tooth plates 33 can be limited, and the stability of the tooth plates 33 during reciprocating movement is ensured.
[0024] The upper part of the plurality of rotating plates 3 is provided with a plurality of second sliding grooves 351, and a plurality of clamping plates 35 are slidingly clamped in the second sliding grooves 351.

[0026] Working principle: in actual use, the driving disc 22 is driven to rotate by the first motor 21, and then the driving block 221 and the limiting block 222 are driven to rotate. When the driving block 221 is slidingly clamped in the driving groove 232, the limiting block 222 does not contact the limiting groove 231 at this time, so that the rotating disc 23 rotates under the eccentric rotation of the driving block 221, that is, the rotating box 2 is driven to rotate. Since the plurality of second gears 26 and the first gear 25 are meshed with each other, when the rotating box 2 is driven to rotate, the second gear 26 will rotate, and then the plurality of rotating plates 3 will rotate under the transmission of the synchronous belt 27. The driving disc 22 drives the rotating disc 23 to rotate by 90° each time, so that the second gear 26 also rotates by 90°. Since the upper part of the rotating plate 3 is fixedly provided with three limiting frames 36, the substrate is placed in the limiting frame 36. Under the rotation of the rotating plate 3, the substrate to be pasted is moved to the lower part of the pasting device 11 each time, so that the pasting work is carried out. One of the four stations is used for unloading and feeding, so that the substrate pasting can be carried out smoothly.
[0027] After the substrate is placed in the limiting frame 36, one of the tooth plates 33 is driven to move to the middle part by the electric push rod 31, so that the other tooth plate 33 moves relatively under the transmission of the third gear 34, so as to clamp and fix the substrate placed in the limiting frame 36.
