Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wiring harness welding, specifically to an electronic wiring harness automatic welding equipment. BACKGROUND

[0002] Wiring harness refers to the transmission line for signal and power between two or more devices, which is generally composed of one or more groups of metal cables, and the cables are connected by welding or terminal method. The traditional wiring harness welding process is mainly divided into fusion welding, thin welding and pressure welding. In the pressure welding process, ultrasonic welding is widely used in wiring harness welding because it does not change the metal characteristics, has good conductivity after welding, has low requirements for metal surface, and has short welding time.

[0003] In the prior art, the core of the cable is generally composed of multiple metal wires spirally wound. During the process of peeling off the insulating skin, the core will be scattered. Before the core and the terminal are welded, the core needs to be tightened to avoid the influence of the scattered core on the welding effect. When multiple cables are welded to the same terminal, the arrangement of the core is time-consuming, and it is difficult to align the core and the terminal when multiple cables are welded at the same time, which requires higher requirements for the operator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] An automated welding device for electronic wire harnesses, comprising:

[0029] Welding assembly 1 includes a base 11, a welding head 13 is mounted on the top surface of the base 11 via a welding machine 12, a welding base 2 is provided on the top surface of the base 11, the welding base 2 includes a welding station 22, a terminal clamp is provided on one side of the welding station 22, and a wire harness clamp 3 is provided on the other side, the wire harness clamp 3 includes a positioning component and a clamping component, the clamping component cooperates with the positioning component to fix the cable and wire core.

[0030] The welding machine 12 is a known ultrasonic welding machine. The welding machine 12 is used to drive the welding head 13 to move in the vertical direction and to drive the welding head 13 to vibrate at high frequency using ultrasonic waves.

[0031] The welding base 2 also includes a mounting plate 21, which is slidably mounted on the top surface of the base 11 via a linear guide rail, and the welding station 22 is slidably mounted on the top surface of the mounting plate 21 via a linear guide rail.

[0032] Mounting plate 21 can slide back and forth on the top surface of base 11, and soldering station 22 can slide left and right on the top surface of mounting plate 21.

[0033] The positions of the mounting plate 21 and the soldering station 22 can be fixed by a known adjustable handle.

[0034] The terminal clamp includes a terminal chuck 23, and a telescopic device 24 is provided on one side of the terminal chuck 23. The terminal chuck 23 is used to fix the terminal 4.

[0035] The terminal clamp 23 has a groove on the left side of its top surface, and the terminal 4 can be placed into the groove on the top surface of the terminal clamp 23.

[0036] The telescopic device 24 can be a linear telescopic device such as a push rod or a pneumatic rod. The terminal clamp 23 is snapped onto the top of the movable rod of the telescopic device 24. The telescopic device 24 can drive the terminal clamp 23 to perform linear reciprocating motion, thereby driving the terminal 4 to move horizontally.

[0037] The positioning component includes a positioning block 31, which is fixedly installed on the side of the welding station 22 by bolts. A positioning plate 32 is provided on the top of the positioning block 31 near the welding station 22, and a guide groove 33 is provided through the middle of the positioning plate 32.

[0038] The top surface of the positioning block 31 is provided with a horizontal groove, which is aligned with the guide groove 33 for positioning the wire harness.

[0039] The guide groove 33 is funnel-shaped, and a limiting protrusion 34 is provided inside the guide groove 33 on the side near the welding station 22. The thickness of the limiting protrusion 34 is the same as the thickness of the cable insulation.

[0040] The guide groove 33 facilitates the rapid positioning of the wire harness, and the limiting protrusion 34 restricts the lateral movement of the wire harness, facilitating the rapid positioning of the wire core.

[0041] The clamping assembly includes a pressure plate 35, which is rotatably mounted on the side of the positioning plate 32 away from the welding station 22, and the pressure plate 35 is connected to a first power source 37.

[0042] The first power source 37 can be an electric motor or a servo motor, used to drive the pressure plate 35 to rotate.

[0043] When the pressure plate 35 rotates toward the positioning block 31, it can compress the wire harness and fix the wire harness.

[0044] When the pressure plate 35 moves away from the positioning block 31, it can release the fixing of the wire harness.

[0045] The pressure plate 35 is provided with a pressure block 36 on the side near the positioning plate 32. The pressure block 36 is inserted into the guide groove 33 and can slide along the guide groove 33 and the limiting protrusion 34.

[0046] When the pressure block 36 moves downward, it can squeeze the wire core. In conjunction with the guide groove 33 and the limiting protrusion 34, it can press the wire core tightly, thereby tightening the wire core and reducing the wire management time.

[0047] In this embodiment, when the operator uses this device, they control the first power source 37 to operate, driving the pressure plate 35 to rotate to a vertical position. At the same time, they control the telescopic device 24 to operate, driving the terminal clamp 23 away from the positioning plate 32.

[0048] Place terminal 4 into terminal clamp 23, then place wire harness into guide groove 33, ensuring that the insulation of wire harness abuts against limiting protrusion 34.

[0049] The first power source 37 is controlled to work, driving the pressure plate 35 to rotate to a horizontal state and press down on the wire harness. At this time, the wire pressing block 36 moves downward to squeeze the wire core. It works in conjunction with the guide groove 33 and the limiting protrusion 34 to press the wire core, thereby tightening the wire core.

[0050] At the same time, the telescopic device 24 is controlled to work, driving the terminal clamp 23 to move towards the positioning plate 32, so that the tail end of the terminal 4 moves to below the wire core.

[0051] The control welding machine 12 operates, driving the welding head 13 to move downwards and press it above the wire core and terminal 4 to weld the wire harness and terminal 4.

[0052] After welding is completed, the first power source 37 is activated to drive the pressure plate 35 to rotate to a vertical position. At the same time, the telescopic device 24 is activated to drive the terminal clamp 23 away from the positioning plate 32.

[0053] At this point, terminal 4 is disengaged from terminal clamp 23. The wire harness and terminal 4 can then be removed from the wire harness clamp 3.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
