The scale mark 17 is at the same interval and the terminal corresponds to the middle position of the rotating frame 7, which is convenient for observing the distance between the two supporting plates 10 and for quick adjustment. A servo motor 3 is fixedly installed on one side of the fixed vertical plate 2, and an electronic drive controller 4 is connected to the lower end of the servo motor 3. The electronic drive controller 4 is used to control the forward and reverse fixed angle of the servo motor 3 Rotate, the servo motor 3 rotates half a circle and then rotates back to prevent the external line from being entangled. A support drive assembly is set inside the rotating frame 7, and the support drive assembly is connected to a fixed assembly. The support drive assembly includes a bidirectional screw rod 8, an adjusting block 9, a supporting plate 10, a connecting block 11, and a support rod 12. A bidirectional screw rod 8 and a support rod 12 that are symmetrical about the center of the rotating frame 7 are set inside the rotating frame 7. A symmetrical supporting plate 10 is set inside the rotating frame 7. The ends of the two supporting plates 10 are fixedly connected to the connecting block 11. The bidirectional screw rod 8 and the support rod 12 rod body pass through the corresponding connecting block 11. An adjusting block 9 is fixedly set at one end of the bidirectional screw rod 8. The bidirectional screw rod 8 can be rotatable as a whole, and the bidirectional screw rod 8 can be screwed with the two corresponding connecting blocks 11. The connecting block 11 outside the support rod 12 is relatively independent of it;

[0020] When adjusting the distance between the two supporting plates 10, rotate the adjusting block 9. The rotation of the adjusting block 9 drives the bidirectional screw rod 8 to rotate. The bidirectional screw rod 8 rotates and screws with the connecting block 11, so that the connecting block 11 and the supporting plates 10 move away from or closer to each other. Determine the position according to the scale mark 17 and adjust the distance between the two supporting plates 10 to facilitate the placement of suitable PCB boards.

The position is determined according to the scale mark 17, and the distance between the two supporting plates 10 is adjusted. Through the external control circuit and the controller, the two telescopic cylinders 13 are controlled to extend at the same time, driving the lifting frame 15 to move upward along the limit frame 14 until the protective pad at the lower end of the pressing plate 16 is separated from the anti-slip pad on the supporting plate 10 and leaving enough space for placing the PCB board. After the PCB board is placed, the two telescopic cylinders 13 are controlled to retract at the same time, driving the lifting frame 15 to move downward along the limit frame 14 until the protective pad at the lower end of the pressing plate 16 presses the PCB board. At this time, the placement machine can place the PCB board. After one side is processed, the servo motor 3 is controlled by the electronic drive controller 4 to rotate, driving the connecting shaft 5, the connecting frame 6, and the rotating frame 7 to rotate, so that the support drive assembly and the fixed assembly are flipped, driving the PCB board to flip, and the placement of the next side can be carried out.
