[0001] This utility model relates to the field of welding workstation technology, specifically to a laser vision weld seam tracking and positioning device. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. A welding workstation is an automated device used for welding materials. Laser vision weld seam tracking and positioning is an advanced technology used to accurately track and position weld seams during the welding process. It mainly consists of a laser light source, a camera, an image processing unit and a control system.

[0003] Currently, laser vision weld seam tracking and positioning devices lack a fume protection mechanism. During operation, the stability of the lens is easily affected by the fumes generated by the welding torch, resulting in mediocre performance. Therefore, this paper proposes a laser vision weld seam tracking and positioning device to incorporate an auxiliary fume protection mechanism. This mechanism utilizes suction, diversion, and cleaning methods to reduce the impact of welding fumes on the device's performance, improve tracking and positioning stability, and ultimately enhance overall effectiveness. Utility Model Content

The welding gun is surrounded by a fixing sleeve connected by bolts. A tracking and positioning component is provided on one side of the fixing sleeve. The bottom of the fixing sleeve is surrounded by a flow guiding component. A positioning component is provided between the fixing sleeve and the tracking and positioning component.

[0006] The flow guiding assembly includes a flow guiding shroud, the bottom of which is bolted to a conical shroud, and the other side of the fixing sleeve is bolted to a micro air pump, with the air inlet of the micro air pump connected to the flow guiding shroud.

[0007] By adopting the above technical solutions, an auxiliary fume protection mechanism can be added, and the impact of welding fumes on the effectiveness of the tracking and positioning device can be reduced by using suction, diversion, and cleaning methods.

[0008] Specifically, the positioning component includes a mounting base, and the mounting base is connected to a fixing sleeve by bolts. Limiting rods are sleeved on both sides of the mounting base, and a compression spring is installed inside the mounting base on the inner side of the limiting rods via a spring seat.

[0009] By adopting the above technical solution, an auxiliary positioning mechanism can be added, and the assembly and disassembly of the tracking and positioning components can be quickly completed using plug-in and snap-fit ​​methods.

[0010] Specifically, the top of the flow guide is connected to a threaded seat by welding, and the flow guide is threadedly connected to the bottom of the fixing sleeve by the threaded seat.

[0011] By adopting the above technical solution, the flow guide can be used through the threaded connection fixing sleeve, which improves the convenience of disassembly and assembly.

[0012] The beneficial effects of this utility model are:

[0013] (1) The laser vision weld seam tracking and positioning device described in this utility model can increase the auxiliary fume protection mechanism by setting a fixed sleeve, a flow guide, a conical cover and a micro air pump.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To minimize the impact of welding fumes on the quality of equipment operation and thus improve its performance, such as... Figures 1-3 As shown, the laser vision weld seam tracking and positioning device of this utility model includes a welding torch 1, a flow guiding component 4 and a positioning component 5. The welding torch 1 is connected to a fixing sleeve 2 by bolts. A tracking and positioning component 3 is provided on one side of the fixing sleeve 2. The bottom of the fixing sleeve 2 is fitted with the flow guiding component 4 around the welding torch 1. The positioning component 5 is provided between the fixing sleeve 2 and the tracking and positioning component 3.

[0023] The flow guiding assembly 4 includes a flow guiding shroud 401. A conical shroud 402 is bolted to the bottom of the flow guiding shroud 401. A micro air pump 403 is bolted to the other side of the fixing sleeve 2, and the air inlet of the micro air pump 403 is connected to the flow guiding shroud 401.

[0024] In use, the auxiliary fume protection mechanism can be added by fixing sleeve 2, guide hood 401, conical hood 402 and air pump 403. By using suction, guiding and cleaning methods, the impact of fume on the tracking and positioning device during welding operations can be reduced.

[0025] To improve the ease of disassembly and assembly operations, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a positioning component 5, which includes a mounting base 501 and a fixing sleeve 2 connected to the mounting base 501 by bolts. Limiting rods 502 are sleeved on both sides of the mounting base 501, and a compression spring 503 is installed inside the mounting base 501 on the inner side of the limiting rods 502 by a spring seat.

[0026] In use, the mounting base 501, the limiting rod 502 and the compression spring 503 can be used to add an auxiliary positioning mechanism, and the assembly and disassembly of the tracking and positioning component 3 can be quickly completed by plugging and snapping.

[0027] For example, such as Figure 2 As shown, the present invention also includes a threaded seat 404 welded to the top of the flow guide 401, and the flow guide 401 is threadedly connected to the bottom of the fixing sleeve 2 via the threaded seat 404.

[0028] In use, the threaded seat 404 facilitates the use of the flow guide 401 through the threaded connection fixing sleeve 2, improving the convenience of disassembly and assembly.

[0029] For example, such as Figure 4 As shown, the present invention also includes a tracking and positioning component 3 comprising a housing 301, a slot 302 corresponding to the mounting base 501 on one side of the housing 301, and limiting holes 303 corresponding to the limiting rod 502 on both sides of the slot 302, with the limiting holes 303 penetrating the housing 301. A tightening screw 304 is threadedly connected to the other side of the housing 301 through a reserved threaded hole.

[0030] In use, the housing 301, the slot 302 and the limiting hole 303 facilitate the snap-fit ​​and plug-fit assembly of the mounting base 501 and the limiting rod 502. Tightening the screw 304 facilitates the use of threaded connections to reinforce the stability of the housing 301 assembly.

[0031] For example, such as Figure 4 As shown, the present invention also includes a camera lens 305 and a laser emitter 306 disposed at the bottom of the housing 301, and a power supply interface 307 and a transmission interface 308 disposed at the top of the housing 301.

[0032] In use, the camera lens 305, laser emitter 306, power supply interface 307 and transmission interface 308 can be used to form a tracking and positioning component 3 to perform laser vision weld seam tracking and positioning operations.

[0033] In use, the tracking and positioning component 3 follows the welding torch 1 during welding. The camera lens 305 and the laser emitter 306 perform laser vision tracking and positioning of the weld seam. At the same time, the micro air pump 403 can be manually turned on to exhaust the fumes generated by the welding torch 1 through the guide shroud 401 and the conical shroud 402, so as to reduce the contact between the fumes and the tracking and positioning component 3, thereby improving the quality of use of the camera lens 305, reducing the residue of surface impurities and dirt, and improving the effectiveness of the device.

[0034] Furthermore, during subsequent maintenance and repair operations, the limiting rod 502 can be pushed back into the mounting base 501 through the limiting hole 303 on the outside of the housing 301, thus separating the mounting base 501 from the housing 301 for quick disassembly and repair. During reassembly, the mounting base 501 is simply inserted into the corresponding slot 302 of the housing 301, and the spring force of the compression spring 503 pushes the limiting rod 502 into the corresponding limiting hole 303 to complete the assembly and fixation. The overall structure is simple and compact, low in cost, easy to operate, and more flexible and reliable in use.
