[0028] When working, the driving component first drives the threaded rod 13 to rotate through the driving motor 14. Since the threaded rod 13 and the slider 9 are threadedly connected, the rotational motion is converted into linear motion with the cooperation of the threaded rod 13 and the slider 9, so that the slider 9 starts to move laterally along the support frame 3 and starts to dispense glue on the circuit board. The setting of the first limit rod 8 is to limit the relative displacement of the slider 9 on the one hand, and to improve the stability of the movement on the other hand. The liquid pump 7 is responsible for pumping out the glue stored in the storage tank 2 and making it drip onto the circuit board through the needle 10 to complete the glue dispensing. The delivery tube 1 is long enough to support the reciprocating movement of the slider 9.

[0030] During operation, the gear 27 is first driven to rotate by the dual-rotor motor 26, and then, in cooperation with the rack 25, the two racks 25 inside the adjustment box 5 on the same side are simultaneously moved toward the center or away from the outside, thereby driving the first longitudinal clamping plate 19 and the second longitudinal clamping plate 23 to move toward the center or away from the outside at the same time, and clamp the circuit board in cooperation with the rubber anti-skid pad 18, and then the transverse clamping plate 17 is driven toward the center by the electric push rod 21, and clamps the circuit board again in cooperation with the rubber anti-skid pad 18, and the second limit rod 22 can ensure the stability of the transverse clamping plate 17 during movement.

[0031] Working principle: When it is necessary to dispense glue on the circuit board, first place the circuit board in the area selected by the four alignment marks 11, and then send a signal to the controller 15 through the control panel 6 to start the dual-rotor motor 26. The dual-rotor motor 26 drives the gear 27 to rotate through the shaft, and in cooperation with the rack 25, drives the second longitudinal clamping plate 23 and the first longitudinal clamping plate 19 to move closer to the middle, and then in cooperation with the rubber anti-skid pad 18, clamps the circuit board longitudinally, and then sends a signal to the controller 15 through the control panel 6 to start the electric push rod 21, and drives the transverse clamping plate 17 to move closer to the middle through the electric push rod 21, and clamps the circuit board transversely in cooperation with the rubber anti-skid pad 18, so as to clamp the circuit board in both the transverse and longitudinal directions, and then starts the liquid pump 7 to extract the glue stored in the storage tank 2 to the needle 10 through the delivery pipe 1, and drips it on the circuit board through the needle 10, and at the same time starts the drive assembly to start moving the slider 9 horizontally, and cooperates with the needle 10 to complete the glue dripping work.
