When the whole device works, the start-stop and working state switching of various motors, air cylinders, welding guns and the like can be controlled by combining various sensors (such as a proximity sensor, a photoelectric sensor and the like) and a control device (such as a PLC + an industrial computer), and the control device is a known technology and is not described in detail herein.
When the whole equipment is welded, the process is as follows:
s10, the motor armature and BUSAR docking device 10 assembled with the motor armature and BUSAR is placed on the positioning placing disk 4010 of the jacking rotating mechanism 40, and the lower end of the motor armature is inserted into the groove of the positioning placing disk 4010 for positioning.
And S20, starting the motor 401 of the jacking rotating mechanism 40, driving the screw rod of the lead screw to rotate through the belt pulley, the belt and the driven wheel and enabling the movable nut on the screw rod to move upwards, so as to drive the mounting block to move upwards and drive the supporting plate 409 to move upwards to the welding height.
S30, the rotating motor 409 of the jacking rotating mechanism 40 is started to drive the supporting disc 409 to rotate, so that the armature of the motor on the supporting disc and the first pair of flat copper wires of the BUSBAR rotate to the welding position.
S40, the electric cylinder of the translation mechanism 60 is started to drive the clamping jaw assembly 50 to move towards the direction of the pair of flat copper wires at the position to be welded, and the two clamping heads 501 are positioned at two sides of the pair of flat copper wires; next, the gripper cylinder 503 is actuated to close the two grippers 501 to clamp a pair of flat copper wires.
And S50, the moving device 30 drives the welding gun 20 to move downwards and move towards the welding position, and after the welding gun 20 moves to the welding position, the welding gun 20 starts to weld and fix the two parts to be welded clamped by the clamping heads 501.
S60, after the welding operation, the moving device 30 drives the welding gun 20 to move out of the welding position, and at the same time, the gripper cylinder 503 drives the two grippers 501 to open, and the translation mechanism 60 drives the gripper assembly 50 to move out of the welding position.
And S70, the rotating motor of the jacking rotating mechanism 40 is started again to drive the motor armature on the rotating motor and the other pair of flat copper wires of the BUSBAR to move to the welding position.
And repeating the steps S40-S70 until all the flat copper wires are completely welded, resetting each mechanism, manually or through automatic equipment, taking the welded workpieces away, placing the next workpiece to be welded on the positioning support plate, and repeating the process.
The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
