[0014] A method for using automobile wiring harness production and assembly equipment comprises the following steps:

[0015] Step 1: In the initial state, the lower surface of the ejector rod contacts the surface of the corresponding ball, and the ejector rod does not control the downward movement of the pressure rod. A plurality of wires with broken ends are placed on a plurality of support frames, and the fourth linear electric rail is controlled to be turned on to drive the second mounting frame, the plurality of support frames, and the plurality of wires to be moved to the bottom of the plurality of positioning members, so as to automatically load the wires.

[0016] Step 2: Control and start the first lifting cylinder to drive the first horizontal frame and the moving mechanism to descend, and the wires to be assembled are placed between the fixed clamping frame and the movable clamping frame in the multiple sets of positioning parts. Subsequently, the first gear is driven by the first motor to rotate, thereby driving the corresponding third horizontal frame and the moving push rod to move to one side of the upward feeding mechanism, and the sinking rod moves to the surface of the ball in the multiple positioning parts. The sinking rod controls the pressure rod to move downward, driving the longitudinal slider and the wedge block to move downward, the second spring contracts, the wedge block presses against the movable clamping frame, and the movable clamping frame moves toward the fixed clamping frame to squeeze the first spring, and the wires to be assembled are positioned through the fixed clamping frame and the movable clamping frame;

[0017] Step 3: Control and open the first lifting cylinder to drive the first horizontal frame, the shifting mechanism and the multiple wires to be assembled to move upward, and the wires are separated from the multiple support frames. Then, control and open the first linear electric rail to drive the first mounting frame and the multiple positioning members to slide stably, and drive the wires to be assembled to slide stably toward one side of the assembly mechanism. At this time, the surfaces of the balls in the multiple positioning members are always in contact with the lower surface of the sinking rod, and the sinking rod continues to resist the pressure rod;

[0018] Step 4, move the wires to be assembled to the position of the assembly mechanism, and insert the connector between the first positioning frame and the second positioning frame through an external device, then control the first telescopic rod to extend and retract, drive the second positioning frame to move close to the first positioning frame, position and load multiple connectors, control the second linear electric rail to drive multiple connectors to move toward one end of the wire, until the end of the wire is inserted into the corresponding connector for automatic assembly of the connector, then control the second lifting cylinder to drive the U-shaped cross frame and multiple wire-pressing parts to descend, until the connector is placed between two wire-pressing side clamps in the multiple wire-pressing parts, then control the second motor to drive the second gear to drive the second crown gear, the male drive shaft and multiple double-headed screws to rotate, and then control the two wire-pressing side clamps in the multiple wire-pressing parts to move toward each other, and the two wire-pressing side clamps compress the connector to automatically fix the connector to the end of the wire, then reset the auxiliary mechanism and the first positioning frame and the second positioning frame;

[0019] Step 5: Control and open the first lifting cylinder to drive the first horizontal frame and the moving mechanism to continue to descend, and the wires move down to the positions of the third positioning frame and the fourth positioning frame, and insert the connector between the third positioning frame and the fourth positioning frame through an external device, and then control the second telescopic rod to drive the fourth positioning frame to move toward the third positioning frame, and position and load multiple connectors, and control and open the third linear electric rail to drive multiple connectors to move toward one end of the wire until the connector at the end of the wire is inserted into the corresponding connector for automatic assembly of the connector, and then reset the third positioning frame and the fourth positioning frame;

[0020] Step six, control to open the first linear electric rail, continue to drive the first mounting frame and multiple sets of positioning parts to perform stable translational sliding, and move the wires and connectors to a side away from the feeding mechanism. At this time, the balls in the multiple positioning parts move from the sinking rod to the position of the top rod, and the second spring extends to drive the longitudinal slider and the wedge block to move upward. The first spring extends to drive the movable clamping frame to move to the side away from the fixed clamping frame, and the wires lose their positioning for automatic unloading.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting up a moving and fixing mechanism and using a feeding mechanism, multiple wires can be automatically fed, positioned and moved, and it is convenient for automatic unloading after the subsequent wire assembly is completed, effectively improving the overall production and assembly efficiency of automotive wiring harnesses.

[0023] 2.
