Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to an automated integrated equipment for laser stripping, twisting and tinning of wire harnesses. Background Technology

[0002] Several automated laser wire stripping solutions exist in the field, but the basic idea is to separate wire bundle processing from laser stripping. Since mechanical structures are unavoidable, and embedding the optical path within the mechanical mechanism is practically impossible, current automated laser wire stripping machines primarily employ laser stripping first, followed by wire bundle cutting, twisting, and tinning processes. The drawback of this approach is that laser stripping causes the wire bundle tension to release, leading to contraction during traction and decreased traction motion accuracy. This, in turn, reduces the accuracy of subsequent mechanical cutting, resulting in significant deviations in the overall positional accuracy of the laser-stripped end. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes an automated integrated device for laser stripping, twisting, and tinning of wire harnesses. This integrated device adds a laser stripping module to the existing technology, enabling laser stripping, cutting, and tinning of wire harnesses without relative displacement. This eliminates the problem of poor wire harness processing accuracy caused by deformation after stress release.

[0004] An automated integrated device for laser stripping, twisting, and tinning of wire harnesses includes a worktable and a straightening mechanism, a first rotary tinning mechanism, a second rotary tinning mechanism, a wire pulling mechanism, a material receiving and clamping mechanism, and a tin furnace mechanism mounted on the worktable. It also includes a laser stripping mechanism, which is arranged opposite to the first cutting, stripping, and twisting mechanism. The laser stripping mechanism and the first cutting, stripping, and twisting mechanism can move relative to each other or towards each other. The worktable is also equipped with a material feeding conveyor belt.

[0005] As a preferred embodiment of the above technical solution, the laser wire stripping mechanism includes a laser wire stripping module and a linear module for driving the laser wire stripping module to move.

[0006] As a preferred embodiment of the above technical solution, the cutting, peeling and twisting mechanism includes a cutting, peeling and twisting module and a linear module II for driving the cutting, peeling and twisting module to move.

[0007] As a preferred embodiment of the above technical solution, a material collection frame is installed at the discharge end of the feeding conveyor belt.

[0008] As a preferred embodiment of the above technical solution, the workbench is also integrated with a PLC control console.

[0009] As a preferred embodiment of the above technical solution, a dust extraction mechanism is also installed on the workbench, and the inlet of the dust extraction mechanism is located close to the laser cutting point of the laser wire stripping module.

[0010] The beneficial effects of this utility model are as follows:

[0011] The innovation of this application lies in adding a laser wire stripping mechanism to the existing technology and adjusting the operation of the cutting, stripping, and twisting mechanism to be adjustable. This ensures that laser stripping, cutting, stripping, and soldering of the wire bundle are achieved without moving the wire bundle, thereby eliminating the problem of poor wire bundle processing accuracy caused by deformation after stress release. Furthermore, a feeding conveyor belt is added, realizing fully automated operation. Attached Figure Description

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1The illustrated automatic integrated device for laser stripping, twisting, and tinning of wire harnesses includes a worktable 1 and, mounted on the worktable 1, a straightening mechanism 2, a first rotary tinning mechanism 3, a cutting, stripping, and twisting mechanism 4, a second rotary tinning mechanism 5, a wire pulling mechanism 6, a material receiving and clamping mechanism 7, and a tin furnace mechanism 8. It also includes a laser stripping mechanism 9, which is positioned opposite to the cutting, stripping, and twisting mechanism 4. The laser stripping mechanism 9 and the cutting, stripping, and twisting mechanism 4 can move relative to each other or towards each other. The worktable 1 is also equipped with a feeding conveyor belt 10. The straightening mechanism 2, the first rotary tinning mechanism 3, the cutting, stripping, and twisting mechanism 4, the second rotary tinning mechanism 5, the wire pulling mechanism 6, the material receiving and clamping mechanism 7, and the tin furnace mechanism 8 are components of existing equipment. Correspondingly, two sets of tin furnace mechanisms 8 are also provided, and their structure and working principle are existing technology, which will not be described in detail here.

[0018] In this embodiment, the laser wire stripping mechanism 9 includes a laser wire stripping module 901 and a linear module 902 for driving the laser wire stripping module 901 to move, such as... Figure 2 As shown. Specifically, the laser wire stripping mechanism 9 consists of a housing containing an optical path, a laser, a reflector and adjustment mechanism, a red light indicator, an optical path switching module, a light shield, a focusing lens adjustment module, an air blower, and a nozzle. Its structure and working principle are also existing technologies.

[0019] In this embodiment, the cutting, peeling, and twisting mechanism 4 includes a cutting, peeling, and twisting module 401 and a linear module 402 for driving the cutting, peeling, and twisting module 401 to move, such as... Figure 3 As shown.

[0020] In this embodiment, a material collection frame 11 is installed at the discharge end of the feeding conveyor belt 10.

[0021] In this embodiment, the workbench 1 is also integrated with a PLC control console 12.

[0022] In this embodiment, a dust extraction mechanism is also installed on the workbench 1, and the inlet of the dust extraction mechanism is located near the laser cutting point of the laser wire stripping module 901. The dust extraction mechanism is not shown in the accompanying drawings.

[0023] The innovation of this application lies in the addition of a laser wire stripping mechanism 9 to the existing technology, and the adjustment of the working position of the cutting, stripping, and twisting mechanism 4 to be adjustable. This ensures that laser stripping, cutting, stripping, and soldering of the wire bundle are achieved without moving the wire bundle, thereby eliminating the problem of poor wire bundle processing accuracy caused by deformation after stress release. Simultaneously, a feeding conveyor belt 10 is added to achieve automated feeding.

[0024] The specific workflow is as follows:

[0025] 1. Based on the length of the stripped wire end, the wire cutting, stripping, and twisting module 401 is driven to the rear of the equipment by the linear module 402, and the laser stripping module 901 moves to the processing area to strip the wire. During laser stripping, the rotating tinning mechanism 3 and the rotating tinning mechanism 5 clamp the wire bundle to keep it horizontal and stable for laser stripping. After laser stripping is completed, the wire cutting, stripping, and twisting module 401 and the laser stripping module 901 are reset.

[0026] 2. The wire cutting knife of the wire cutting, stripping and twisting module cuts the wire harness, and the first rotating tinning mechanism clamps the next section of the wire harness, while the second rotating tinning mechanism clamps the previous section of the wire harness.

[0027] 3. The insulation layer of the wire harness processed in the next section is removed by the stripping knife of the wire cutting, stripping and twisting module and the first rotary soldering mechanism. The wire is twisted by the rubbing knife of the wire cutting, stripping and twisting module and the first rotary soldering mechanism. The insulation layer of the wire harness processed in the previous section is removed by the stripping knife of the wire cutting, stripping and twisting module and the second rotary soldering mechanism. The wire is twisted by the rubbing knife of the wire cutting, stripping and twisting module and the second rotary soldering mechanism. Then, the first rotary soldering mechanism and the second rotary soldering mechanism apply flux and solder respectively.

[0028] 4. The wire harness that has been processed in the previous section has completed the processing of both ends. It is moved by the receiving clamping device to the unloading conveyor belt, and then transported by the latter to the collection box.

[0029] 5. The next section of the wire harness is stretched to the cutting length using a wire pulling device, and then prepared for the next section of laser stripping.

[0030] The smoke and dust extraction mechanism is a standard function and will not be described in detail here; the control system and control method will also not be described in detail.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
