[0016] Figure 1 This is a schematic diagram of the structure of this utility model.

[0017] An automatic cleaning machine for sensor PCB boards includes a multi-axis moving mechanism 1, an opening and closing mechanism 2, board clamping blocks 3, an ultrasonic cleaning tank 4, a loading frame 5, a frame swinging mechanism 6, and a PCB board lifting mechanism 7. The opening and closing mechanism 2 is installed on the multi-axis moving mechanism 1, and two opposing board clamping blocks 3 are installed on the opening and closing mechanism 2. The PCB board lifting mechanism 7, the ultrasonic cleaning tank 4, and the frame swinging mechanism 6 are located below the multi-axis moving mechanism 1. The loading frame 5 is detachably connected to the frame swinging mechanism 6.

[0018] The multi-axis moving mechanism 1 includes a horizontal linear module 11, a lifting electric cylinder 12, and a rotary motor 13. The slide of the horizontal linear module 11 is fixed on the cylinder body of the lifting electric cylinder 12, and the rotary motor 13 is fixed on the piston rod of the lifting electric cylinder 12.

[0019] The horizontal linear module 11 can drive the plate clamping block 3 to move horizontally in a straight line, the lifting electric cylinder 12 can drive the plate clamping block 3 to move up and down, and the rotary motor 13 can drive the plate clamping block 3 to rotate in the horizontal plane.

[0020] The opening and closing mechanism 2 includes a cylinder 21, a slide 22, a motor, a synchronous pulley, and a synchronous belt. Two synchronous pulleys are rotatably connected inside the cylinder 21. The output shaft of the motor is fixed on one of the synchronous pulleys. Both synchronous pulleys are meshed on the synchronous belt. The two sides of the synchronous belt are fixed on the two slides 22 respectively. Both slides are slidably fitted onto the cylinder 21. The cylinder 21 is fixed on the output shaft of the rotary motor 13.

[0021] The motor drives the synchronous pulley to rotate, which in turn drives the synchronous belt to move along the two synchronous pulleys. The driven synchronous pulleys will cause the two slide blocks 22 to move in opposite directions or in a straight line relative to each other along the cylinder body 21.

[0022] The inner side of the board clamping block 3 is provided with a slot for inserting the side of the PCB board. When the two board clamping blocks 3 clamp the PCB board, the front and rear sides of the PCB board will be embedded into the slots of the two board clamping blocks 3.

[0023] Loading frame 5 is a grid frame. Excess liquid will be ejected from the grid.

[0024] The frame swing mechanism 6 includes a rotary cylinder 61, a rotating rod 62, and a support base 63. The rotating rod 62 is rotatably connected to the top of the support base 63, and the output shaft of the rotary cylinder 61 is fixed to one end of the rotating rod 62.

[0025] The rotary cylinder 61 drives the rotating rod 62 to rotate, and the rotating rod 62 can drive the loading frame 5 to swing back and forth.

[0026] A hook 8 for hooking the loading frame 5 is fixed on the rotating rod 62.

[0027] The PCB board lifting mechanism 7 includes a positioning table 71, a lifting plate 72, and a lifting cylinder 73. The lifting cylinder 73 is located below the positioning table 71, and its piston rod is fixed to the lifting plate 72. When the PCB board is placed on the positioning table 71, the lifting cylinder 73 drives the lifting plate 72 to move upward, and the lifting plate 72 lifts the PCB board away from the positioning table 71.

[0028] The working method of this application is as follows: First, the PCB board is placed on the PCB board lifting mechanism 7, which lifts the PCB board to the picking height. Then, the multi-axis moving mechanism 1 drives the two board clamping blocks 3 to move and hold the PCB board. Next, the PCB board is placed in the ultrasonic cleaning tank 4 for ultrasonic cleaning. Finally, the PCB board is placed in the loading frame 5, and the frame swinging mechanism 6 drives the loading frame 5 to swing back and forth, thereby drying the liquid on the PCB board.
