[0019] Please refer to Figures 1 to 5 , in this embodiment, a cleaning device for circuit board production is provided, including a U-shaped seat 1 and a lower cavity 2. A bottom plate is installed in the middle of the U-shaped seat 1. The upper end surface of the bottom plate is rotatably installed with the lower cavity 2 through a pin shaft. An adjustment cavity 11 is installed on the front side end surface of the lower cavity 2. The bottom of the adjustment cavity 11 is rotatably installed with an adjustment lead screw 12 through a bearing. An adjustment slider is screwed on the outer side wall of the adjustment lead screw 12. An upper cavity 13 is installed on the rear side end surface of the adjustment slider. Outer ring frames are installed on the left and right side walls of the U-shaped seat 1. A first screw rod 14 is screwed on the outer side wall of the outer ring frame. The bottom of the first screw rod 14 is connected to the upper end surface of the upper cavity 13 by screwing. First electric sliders 19 are symmetrically installed on the left and right sides of the inner bottom of the U-shaped seat 1. A fixed blower 15 is installed on the upper end surface of the first electric slider 19. The outer end of the outer ring frame is installed with a pull rod 21 through a sliding fit. The inner end of the pull rod 21 is installed with an inner plate. A second electric slider 22 is installed on the inner end of the inner plate. A vacuum cleaner body 16 is installed on the inner end of the second electric slider 22. The outer end of the pull rod 21 is installed with a fixing plate. The fixing plate is connected to the outer ring frame by clamping. The electric slider is a linear guide slider structure, and the device is linearly moved by driving the lead screw to rotate by a motor. During operation, the circuit board is placed in the lower cavity 2, and the adjustment lead screw 12 is rotated to drive the upper cavity 13 to move downward to press and fix the top of the circuit board, facilitating the limit treatment of circuit boards of different specifications. The first screw rod 14 plays a role in limiting and fixing the top of the upper cavity 13. The second electric slider 22 is started, and the vacuum cleaner moves back and forth, facilitating the dust removal treatment of the left and right side walls of multiple circuit boards to ensure the cleaning effect. Subsequently, the pull rod 21 is pulled outward, the first screw rod 14 is rotated, and the upper cavity 13 is flipped so that the circuit board is placed horizontally. The first electric slider 19 is started to drive the fixed blower 15 to move back and forth. The fixed blower 15 blows hot air, thereby being able to dry the circuit board.

[0020] Side plates are installed on the left and right side walls of the U-shaped seat 1. A spring rod 17 is installed on the upper end surface of the side plate. A pressing plate 18 is installed on the upper end surface of the spring rod 17. During operation, when the circuit board is placed horizontally, the spring rod 17 drives the side plate to press down to fix the upper cavity 13, avoiding damage to the circuit board caused by the shaking of the upper cavity 13 during the operation of the fixed blower 15.

[0021] A control panel 23 is installed on the left end face of the U-shaped seat 1. The control panel 23 is electrically connected to both the first electric slider 19 and the second electric slider 22. During operation, a PLC program is written in the control panel 23 to control the operation of each device.

[0022] A rear plate 24 is rotatably installed on the rear end face of the lower cavity 2 through a pin shaft. The rear plate 24 is connected to the upper cavity 13 in a clamping manner. Cotton pads 25 are arranged on the inner sides of both the upper cavity 13 and the lower cavity 2. During operation, the rear plate 24 seals and fixes the rear part of the lower cavity 2 to prevent the circuit board from detaching during the cleaning process. The cotton pad 25 structure is adopted to provide shock absorption and protection for the connection between the circuit board and the lower cavity 2 and the upper cavity 13.

[0023] During specific operation, place the circuit board in the lower cavity 2, rotate the adjusting lead screw 12 to drive the upper cavity 13 to move downward to press and fix the top of the circuit board, which is convenient for limiting circuit boards of different specifications. The first screw rod 14 plays a role in limiting and fixing the top of the upper cavity 13. The second electric slider 22 starts, and the vacuum cleaner moves back and forth to facilitate dust removal from the left and right side walls of multiple circuit boards to ensure the cleaning effect. Then, pull the pull rod 21 outward, rotate the first screw rod 14, and flip the upper cavity 13 to place the circuit board horizontally. The first electric slider 19 starts to drive the fixed blower 15 to move back and forth, and the fixed blower 15 blows hot air to dry the circuit board.
