[0015] Firstly, this utility model, by setting up a movable plate, a threaded sleeve, a fixed ring, a slider, and an annular groove, automatically screws on the threaded sleeve when the distance between the two positioning plates needs to be adjusted according to the size of the PCB to be welded. The threaded sleeve rotates on the slide rod via its thread, moving simultaneously and causing the slider at its end to rotate via a pulley in the annular groove inside the fixed ring. During rotation, the limiting block pulls the fixed ring and the movable frame on the slide rod, thereby adjusting the position of the movable frame and thus the distance between the two positioning plates to accommodate PCBs of different sizes.

[0016] Secondly, this utility model, through its configuration, places six PCB boards on a placement plate, with the front end of each PCB board slightly extending beyond the front end of the placement plate. Once the PCB boards on the positioning plate are about to be soldered, the first motor is controlled to operate. The internal technology of the first motor is existing technology. After the first motor operates, it drives the lead screw at the output end to rotate. The lead screw, through a threaded sleeve, drives the moving plate downwards, causing the bottom placement plate and PCB board to move until they align with the insertion slot on the positioning plate. Then, the electric lead screw shaft is controlled to operate, driving the mounting bracket at the output end and the second motor to move inwards, causing the drive roller at the output end of the second motor to adhere to both sides of the PCB board. Then, the second motor is controlled to operate, driving the drive roller at the output end to rotate. The drive roller, through the friction pad on the outer wall, moves the PCB board to the front end and into the conveyor belt inside the positioning plate via the insertion slot. This allows for the connection and loading of PCB boards without the need for manual placement by workers. Attached Figure Description
