A driving wheel is provided at the output end of the motor 21, and the driving wheel and the driven wheel 23 are driven by a synchronous belt 22, and the synchronous belt 22 is fixedly connected to the adsorption bracket 3. The motor 21 controls the rotation of the driven wheel 23 through a conveyor belt, and the synchronous belt 22 drives the adsorption bracket 3 to move. The movement of the adsorption bracket 3 on the frame 1 is changed by controlling the direction and speed of the motor 21.

[0020] The adsorption bracket 3 includes an upper adsorption bracket 32 ​​and a lower adsorption bracket 31.

The adsorption bracket 3 is in rolling contact with the slide rails 111 through the rollers 34.

[0021] The upper adsorption frame 32 includes an upper bracket 321, a first lifting cylinder 323 and an upper rod 322. The first lifting cylinder 323 is provided at both ends of the upper bracket 321, the output end of the first lifting cylinder 323 is fixedly connected to one end of the upper rod 322, and the other end of the upper rod 322 is provided with an adsorption mechanism 35. The lower adsorption frame 31 includes a lower bracket 311, a second lifting cylinder 313 and a lower rod 312; the second lifting cylinder 313 is provided at both ends of the lower bracket 311, the output end of the lifting cylinder 33 is fixedly connected to one end of the lower rod 312, and the other end of the lower rod 312 is provided with an adsorption mechanism 35. The first lifting cylinder 323 controls the lifting and lowering of the upper rod 322 and the lower rod 312, and the length of the upper rod 322 is longer than the length of the lower rod 312. The adsorption mechanism 35 includes a fixed frame 352, a main air pipe 351 and an air nozzle 353; the fixed frame 352 is fixedly connected to the end of the lower rod 312 or the upper rod 322, and a plurality of air nozzles 353 are arranged in the length direction of the fixed frame 352, and the air nozzles 353 are all connected to the main air pipe 351, and the main air pipe 351 is connected to an external air pump.
