Description

Technical field

[0001] The present invention relates to the technical field of wire harness welding, in particular to the technical field of a wire harness automatic welding machine. [Background Technology]

[0002] Automotive electronics has always occupied an important position in automobile manufacturing. With the development of the automotive industry, the requirements for automotive electronics have become increasingly stringent. To ensure that the functional components of automotive electronics can achieve their functions, automotive wiring harnesses are needed as a bridge to connect the various electronic parts of the car. The ends of the two wiring harnesses need to be docked.

[0003] Currently, most of the processes are done manually by placing the two wire harness ends on top of each other on a welding table, then fixing the back halves of the two wire harnesses by hand, and then welding them using a welding machine. However, manual work inevitably causes shaking when fixing the wire harnesses, which can lead to errors in welding. In addition, the workload is also high when the work is done completely manually.

[0004] In order to solve the problems raised in the background technology, for example, application number: CN202122784546.9 discloses a wire harness welding device, including a main body, wherein two placement plates are provided on the main body for placing the wire harnesses to be welded, and a welding table for docking the two wire harness ports is provided in the middle of the two placement plates. By placing the two wire harnesses in the middle of the placement plates, and then placing the two ends to be welded inside the welding table and overlapping them, the motor drives the welding table and the two placement plates to move inward synchronously through the first threaded rod, and the two flat gears rotate in conjunction with the two rotating grooves while moving horizontally. The two flat gears drive the two sets of clamping plates to move relative to each other through the first transmission assembly to clamp the wire harnesses. At the same time, the first threaded rod drives the welding machine to descend through the second transmission assembly. When the welding machine descends and inserts into the docking groove, the two wire harnesses are also clamped and fixed by the clamping plates, and then welding can be performed by the welding machine. However, the device still has the following defects:

[0005] The wire harness needs to be peeled before welding, and welding can only be performed after peeling. However, the device lacks a peeling structure, which results in the wire harness needing to be manually peeled before welding. The operation is cumbersome and requires the use of multiple tools. It is time-consuming and labor-intensive, and the processing efficiency is low. [Summary of the invention]

[0006] The purpose of the present invention is to solve the problems in the prior art and to propose an automatic wire harness welding machine that can automatically strip the wire harness and automatically perform welding processing after stripping is completed.

Away, the side walls of the two moving blocks are connected with an electric telescopic rod, and the ends of the two electric telescopic rods are connected with a peeling mechanism, which includes a concave support seat, a cylinder 1, a hydraulic rod 1, and an upper cutter. The rear side wall of the concave support seat is connected to the electric telescopic rod, and a cylinder 1 is provided on the outer upper part of the concave support seat, and a hydraulic rod 1 is provided on the inner lower part of the concave support seat. The output end of the cylinder 1 passes through the inner lower part of the concave support seat and is connected to the hydraulic rod 1. The lower part of the hydraulic rod 1 is connected to the upper cutter, and a fixing mechanism is symmetrically provided above the base. The welding mechanism is provided above the middle part of the front side wall of the vertical plate, and the control panel is provided on the side wall of the base. The control panel is electrically connected to the drive motor, the electric telescopic rod, and the cylinder 1 through wires.

[0008] Preferably, a lower cutter cooperating with the upper cutter is provided on the upper inner portion of the concave support seat, and the lower cutter and the upper cutter are arranged in correspondence with each other.

[0009] Preferably, the fixing mechanism includes a fixing seat, a support rod, a top plate, a second cylinder, a second hydraulic rod, and a fixing block. Several support rods are arranged above the fixing seat, and a top plate is commonly arranged above each of the support rods. A second cylinder is arranged above the top plate, and a second hydraulic rod is arranged below the top plate. The output end of the second cylinder passes through the bottom of the top plate and is connected to the second hydraulic rod.

[0014] Beneficial effects of the present invention:

[0015] The present invention can automatically complete the integrated operation of stripping and welding by rotating the screw rod, driving motor 1, moving block, electric telescopic rod, stripping mechanism fixing mechanism and welding mechanism, which greatly improves the processing efficiency. First, the two wire harnesses to be processed are respectively placed in the grooves on the two fixing seats, and then the ends of the two wire harnesses are pulled outward and close to each other and fit together. Subsequently, cylinder 2 is started, and cylinder 2 drives hydraulic rod 2 to descend, and hydraulic rod 2 drives the fixing block to descend until the inner side surface of the fixing block is fit and fixed with the outer side of the wire harness. After the fixing is completed, the driving motor is started, and the driving motor drives the rotating screw rod to rotate, so that the two moving blocks are close to each other until the stripping mechanism is aligned with the wire harness end. After alignment, the driving motor is turned off and the electric telescopic rod is started. The electric telescopic rod extends forward and drives the concave support seat to move forward until the upper cutter and the lower cutter on the inner side of the concave support seat are aligned with the upper and lower surfaces of the wire harness end. After alignment, the control panel is used to control cylinder 1 to start, and cylinder 1 drives When the hydraulic rod descends, the hydraulic rod drives the upper cutter to descend until the outer skin of the wire harness end is cut. After cutting, the drive motor is started again, and the drive motor drives the rotating screw to rotate, so that the two moving blocks are close to each other, thereby driving the upper cutter and the lower cutter to move horizontally to strip the outer skin of the wire harness end, so that the stripped outer skin automatically falls into the opening and falls into the receiving box through the opening, thereby completing the stripping of the outer skin of the wire harness end. Subsequently, the stripping mechanism is driven to move backward by the contraction of the electric telescopic rod, and then the cylinder three is started. The cylinder three drives the hydraulic rod three to descend, and the hydraulic rod three drives the welding machine to descend, thereby welding the ends of the two wire harnesses. Therefore, the device can automatically strip the wire harness, and automatically perform welding processing after stripping is completed. The operation is simple, time-saving and labor-saving, and greatly improves work efficiency. It solves the problem of lack of stripping structure, which results in the need for manual stripping of the wire harness before welding, which is cumbersome to operate, requires the use of multiple tools, is relatively time-consuming and labor-intensive, and has low processing efficiency.
