The stepper motor 16 is fixedly mounted on the docking platform 1, and the first transmission frame 4 is fixedly arranged on one side of the stepper motor 16. The output shaft of the stepper motor 16 is connected to the ball guide shaft 6 through a coupling. The ball guide shaft 6 is rotatably connected to the first transmission frame 4 and the second transmission frame 5. The first transmission frame 4 and the second transmission frame 5 are both provided with a tensioning mechanism 10. The flat belt 12 is sleeved on the tensioning mechanism 10 and the ball guide shaft 6. A support plate is provided under the flat belt 12 for supporting the flat belt 12 and the PCB board 14 placed on the flat belt 12. The stepper motor 16 drives the ball guide shaft 6 to rotate, thereby driving the flat belts 12 on the first transmission frame 4 and the second transmission frame 5 to move horizontally synchronously.

[0022] Furthermore, the limiting unit includes a servo motor 17, a synchronous wheel 18, a first lead screw 8.1 and a second lead screw 8.2. The servo motor 17 is fixedly mounted on the docking platform 1, and the output shaft of the stepper motor 16 is connected to the synchronous wheel 18 through a first synchronous belt. The synchronous wheel 18 is connected to the first lead screw 8.1, and the first lead screw 8.1 is connected to the second lead screw 8.2 through a second synchronous belt 13. The first lead screw 8.1 and the second lead screw 8.2 are respectively connected to the first transmission frame 4 and the second transmission frame 5 through threaded transmission. The servo motor 17 drives the first lead screw 8.1 and the second lead screw 8.2 to rotate synchronously through the synchronous wheel 18 and the second synchronous belt 13, thereby driving the second transmission frame 5 to move horizontally.

[0023] Furthermore, the limiting unit also includes a guide shaft 9, one end of the two guide shafts 9 is fixed on the first transmission frame 4, and the other end is fixed on the fixed platform 2 on the docking platform 1. The two guide shafts 9 are respectively arranged on both sides of the first screw 8.1 and the second screw 8.2 and are slidably connected to the second transmission frame 5. The guide shafts 9 are used to maintain the stable movement of the second transmission frame 5.

[0024] Furthermore, a limit sensor 7.1 is provided on one side of the second transmission frame 5, and a limit switch 7.2 is provided on the second transmission frame 5 to match the limit sensor 7.1. When the limit switch reaches the limit sensor 7.1, the servo motor 16 and the stepper motor 17 stop running.
