[0028] The utility model provides: a PCB board etching device, such as Figure 1-4 As shown, it includes a mounting base plate 1 and an etching box 3 and a cleaning water tank 5 fixedly mounted on the upper surface of the mounting base plate 1. A rotating disk 2 is rotatably arranged on the upper surface of the mounting base plate 1, and the etching box 3 and the cleaning water tank 5 are symmetrically arranged on both sides of the rotating disk 2;

[0029] The upper surface of the rotating disk 2 is provided with a moving component for driving the PCB to move up and down;

[0031] An L-shaped connecting rod 8 is fixedly connected to the side of the clamping block 18, and a clamping component 7 for fixing the PCB board is provided at the bottom end of the L-shaped connecting rod 8. The L-shaped connecting rod 8 is set to be L-shaped to ensure that after the moving component drives the L-shaped connecting rod 8 to move downward, the PCB board will first enter the etching box 3, and at this time the L-shaped connecting rod 8 does not contact the etching box 3, the clamping component 7 fixes the PCB board, and then the rotating disk 2 drives the moving component to rotate, and drives the clamping component 7 to move to the upper surface of the etching box 3, and the moving component drives the clamping component 7 to move down into the etching box 3. When the etching of the PCB board is completed, the moving component drives the PCB board to rise, and the rotating disk 2 drives the PCB board to rotate above the cleaning water tank 5, and then the moving component drives the PCB board to enter the cleaning water tank 5 for cleaning, thereby avoiding the need for staff to manually clean the PCB board, thereby improving work efficiency while avoiding injuries to staff.

[0034] Furthermore, two groups of external threads in opposite directions are symmetrically provided on the outer arc surface of the threaded rod 22, and the two groups of movable protrusions 26 are respectively threadedly sleeved on the outer arc surfaces of the two groups of external threads in opposite directions.

By operating the operating rod 20, the connecting plate 17 is driven to rotate, thereby driving the rotating disk 2 to rotate on the upper surface of the mounting base plate 1.

[0037] Preferably, a sliding groove 21 corresponding to the sliding ball head 11 is provided on the upper surface of the mounting base plate 1, and a moving groove 15 corresponding to the column of the spring plunger 14 is provided inside the sliding groove 21, and two groups of positioning holes corresponding to the ball end of the spring plunger 14 are provided inside the moving groove 15, and the sliding ball head 11 moves inside the sliding groove 21, and the sliding groove 21 is set in a semicircular ring shape, so that the rotation angle of the rotating disk 2 is limited by the sliding ball head 11, ensuring that the rotating disk 2 can only make repeated rotations of 180 degrees, and when the clamping assembly 7 rotates to just above the etching box 3 and the cleaning water tank 5, the spring plunger 14 is correspondingly inserted into the two groups of positioning holes, thereby ensuring that the clamping assembly 7 can be rotated to just above the etching box 3 and the cleaning water tank 5.

[0038] It is worth mentioning that a water pump 6 is provided at the bottom end of the cleaning water tank 5, and a water pipe 12 is sealed at the top of the water pump 6, and a plurality of groups of water spray heads 13 are sealed on the outer arc surface of the water pipe 12. The water inside the cleaning water tank 5 is sucked up by the water pump 6 and transmitted to the plurality of water spray heads 13 through the water pipe 12, so that the PCB board is flushed by the plurality of water spray heads 13, thereby ensuring that the etching liquid on the surface of the PCB board is rinsed clean.

[0039] Specifically, the top of the etching box 3 and the cleaning water tank 5 are both plugged with a top cover 4, and the sides of the two sets of top covers 4 are fixedly connected with pull rings. When the PCB board is not being processed, the upper surface of the etching box 3 and the cleaning water tank 5 is covered by the top cover 4 to prevent dust from entering the etching box 3 or the cleaning water tank 5 and affecting subsequent use.

[0040] In addition, the clamping assembly 7 is located directly above the etching box 3, and the L-shaped connecting rod 8 does not contact the etching box 3. The clamping assembly 7 is located directly above the etching box 3 to ensure that after the moving assembly drives the clamping assembly 7 to move downward, the PCB board can enter the etching box 3 for etching, and when the rotating disk 2 rotates 180 degrees, the clamping assembly 7 is located directly above the cleaning water tank 5, thereby flushing the PCB board.
