By arranging the mounting box 9, the cleaning structure is provided, the circuit board 12 can be cleaned in advance, the use practicability of the circuit board positioning and jet printing device is improved, and meanwhile, when the cleaning of the circuit board 12 is completed, the circuit board 12 is moved between the two sets of clamping plates 13. The operator rotates the hand wheel 28 by hand. The hand wheel 28 drives the bidirectional screw rod 24 to rotate. Since the bidirectional screw rod 24 and the two sets of screw sleeve 25 are threadedly matched with each other, the rotating bidirectional screw rod 24 can drive the two sets of screw sleeve 25 to move close to each other. The two sets of screw sleeve 25 drive the two sets of clamping plates 13 to move synchronously. When the plurality of contact pads 26 are in close contact with the circuit board 12, the hand wheel 28 is stopped, the PLC controller is energized again, the electric telescopic rod 3 is extended, the jet printer 4 is moved to the right, the distance between the infrared range finder 5 and the circuit board 12 reaches the preset value, a signal is sent to the PLC controller, the PLC controller drives the jet printer 4 to work, and the jet printer 4 can perform jet printing on the circuit board 12. When the jet printing is completed, the electric telescopic rod 3 is reset, the hand wheel 28 is rotated counterclockwise, the counterclockwise rotating bidirectional screw rod 24 can drive the two sets of screw sleeve 25 to move away from each other and reset, and the circuit board 12 is ready for use next time. By arranging the clamping plate 13, the dismounting and mounting of the circuit board 12 can be completed at one time, and the circuit board positioning and jet printing device is convenient for the mounting of the circuit board 12.
