Description

Technical Field

[0001] The invention relates to the field of screw driving, and in particular to an automatic screw driving device for assembling a massage chair. Background Art

[0002] Automatic screw locking machine, also known as automatic screw feeding machine, automatic screw feeding and locking machine, industrial tightening system, screw locking robot, etc., is a machine used to replace traditional manual screw tightening. Manual screw tightening includes pure manual tightening and electric screwdriver or pneumatic screwdriver tightening. The latter generates rotational power by electric or pneumatic means to replace frequent manual tightening actions, which to some extent reduces the intensity of screw locking work. However, since manual placement of screws and alignment of screw heads still take up a lot of working time and energy, the overall efficiency improvement is relatively limited.

[0003] When traditional screw driving machines are used, screws are usually driven one by one, which is inconvenient for batch driving of workpieces. Moreover, when driving screws in batches, screws need to be driven at the same position, which is inconvenient for positioning. Generally, lines are drawn with chalk or the like, which is troublesome, and the lines are easily smeared out, which will affect the observation of the marked position and make it impossible to accurately drive screws into the workpiece. Therefore, it is urgent to design an automatic screw driving device for massage chair assembly to solve the positioning problem in screw driving. Summary of the invention

[0016] The present invention can perform preliminary marking by setting a laser lamp, and at the same time, by bending the universal rod, the irradiation direction of the laser lamp can be adjusted and controlled to mark different positions of the workpiece. By setting a second motor, combined with the cooperation of the gear and the rack, the marked position can be repeatedly hammered with a pressure plate, so that the marked position is concave, so as to provide a striking reminder of the screwing position, and the screwing can be more accurately performed. Through the control of the third motor, the torque gun is repeatedly pushed by a cam, and then the turntable is driven by the first motor to rotate slowly in a circle, so that the workpiece can be evenly screwed, and the efficiency of screwing can be improved.
