When the distance between the distance sensor and the first connecting plate reaches the first threshold preset by the distance sensor, the electric push rod is controlled to stop working for a certain period of time and then work in the reverse direction. At the same time, the double-rod cylinder is controlled to drive the clamping plate to move. After the clamping plate moves to contact with the circuit board, the circuit board is clamped.

After the etching process is completed, the electric push rod works in the reverse direction, so that the electric push rod drives the clamping plate, the distance sensor and the circuit board to rise. When the distance between the distance sensor and the first connecting plate reaches a second threshold value preset by the distance sensor, the electric push rod is controlled to stop working, and the drive motor is controlled to work at the same time, so that the drive motor continues to drive the turntable to rotate. When the second infrared transmitter rotates to just above the second infrared receiver, the second infrared receiver captures the signal of the second infrared transmitter, thereby controlling the drive motor.

When the distance between the distance sensor and the first connecting plate reaches the third threshold value preset by the distance sensor, the electric push rod is controlled to stop working for a certain period of time and then work in the reverse direction. After the cleaning is completed, the electric push rod works in the reverse direction, so that the electric push rod drives the clamping plate, the distance sensor and the circuit board to rise. When the distance between the distance sensor and the first connecting plate reaches the second threshold value preset by the distance sensor, the electric push rod is controlled to stop working.
