Description

Technical Field

[0001] This utility model relates to the field of welding robot equipment technology, and in particular to a visual positioning welding device. Background Technology

[0002] Chinese patent CN222790962U discloses a welding robot with welding position positioning function. It uses a vision positioning device to assist the welding torch in performing visualized automatic welding operations, which has the advantages of high work efficiency and good welding effect. However, in the actual operation, welding fumes are generated at the welding point. These fumes will drift around the welding point. When the amount is small, there will be no adverse effects. However, if welding is carried out in the same position for a long time, a large amount of welding fumes may be generated. At this time, the large amount of welding fumes will rise and may adhere to the lens of the vision positioning device, which will contaminate the lens and affect the subsequent normal positioning. Therefore, welding needs to be carried out intermittently, which will take longer when welding in the same place for a long time, and the overall efficiency will not be improved. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a visual positioning welding device, which solves the problem that existing technologies require more resources to avoid generating a large amount of welding fumes, thus failing to improve overall efficiency.

[0004] According to an embodiment of this utility model, a visual positioning welding device includes a welding robot with a robotic arm. A mounting head is located at the end of the robotic arm, and a welding torch and a visual positioning device are mounted on the mounting head. A mounting plate is also fixedly connected to the mounting head. The welding torch has a welding end facing away from the mounting plate and a wiring end close to the mounting plate. A suction pipe is detachably connected to the mounting plate, with an inlet end facing the welding end of the welding torch and the other end passing through the mounting plate. The suction pipe and the visual positioning device are positioned on opposite sides of the welding torch. Similar to existing technologies, this solution also uses a visual positioning device to assist in achieving visualized automatic welding operations. The difference lies in the additional suction pipe, which can be connected to an external exhaust system. The exhaust system can extract welding fumes generated near the welding torch through the suction pipe, thereby reducing the amount of welding fumes and preventing adverse effects on the lens of the visual positioning device. This allows for continuous welding, solving the problem in existing technologies where avoiding large amounts of welding fumes requires more effort, resulting in a lack of overall efficiency improvement.

[0005] Furthermore, a connecting sleeve is fixedly connected to the mounting plate, and the suction pipe is threadedly connected to the connecting sleeve.

[0006] Furthermore, the end of the inlet facing away from the suction tube has a flared structure.

[0007] Furthermore, a connecting thread section is provided on the outer wall of the end of the suction tube opposite to the inlet end.

[0008] Furthermore, perforations are also provided on the mounting plate.

[0009] Furthermore, the mounting plate includes a connecting section fixedly connected to the mounting head and a mounting section fixedly connected to the connecting section, the mounting section and the connecting section having a bent structure and located obliquely above the visual positioning device.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By setting an intake pipe on the side of the welding torch away from the vision positioning device and connecting it to an external exhaust device, the exhaust device can remove the welding fumes generated near the welding torch through the intake pipe, thereby reducing the amount of welding fumes and preventing them from adversely affecting the lens of the vision positioning device. As a result, welding can be carried out continuously, solving the problem in the prior art that it is more common to spend more time to avoid generating a large amount of welding fumes, which leads to the lack of improvement in overall efficiency.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In an exemplary implementation, such as Figure 1-3 As shown, this embodiment provides a visual positioning welding device, which includes a welding robot 1, a robotic arm 2, and a mounting head 3 at the end of the robotic arm 2. A welding torch 4 and a visual positioning device 5 are mounted on the mounting head 3. The visual positioning device 5 has a lens 6 to assist the welding torch 4 in achieving visualized automatic welding. Unlike existing technologies, this solution also has a mounting plate 7 fixedly connected to the mounting head 3. The welding torch 4 has a welding end facing away from the mounting plate 7 and a wiring end close to the mounting plate 7. The wiring end is for connecting a cable 10 to the welding torch 4. The mounting plate 7 also has a through hole 8 for the cable 10 to pass through. A suction pipe 9 is detachably connected to the mounting plate 7. The suction pipe 9 has an inlet end 11 facing the welding end of the welding torch 4. The other end of the suction pipe 9 passes through the mounting plate 7 and can be connected to an external exhaust device. During welding, the exhaust device operates simultaneously, and the exhaust device and the suction pipe 9 can be connected by a flexible hose 12. In this way, the exhaust device can suck in the welding fumes generated during welding through the flexible hose 12 and the suction pipe 9, thereby preventing the welding fumes from drifting towards the lens 6 and avoiding adverse effects on the lens 6 of the vision positioning device 5. Therefore, welding can be carried out continuously, solving the problem in the prior art that it is more common to consume more resources to avoid the generation of a large amount of welding fumes, resulting in no improvement in overall efficiency. Furthermore, in this solution, the suction pipe 9 and the vision positioning device 5 are located on both sides of the welding torch 4, that is, the welding fumes are sucked in on the side away from the lens 6, which further reduces the impact of welding fumes on the lens 6.

[0020] like Figure 1-3 As shown, in a further embodiment, a connecting sleeve 13 is fixedly connected to the mounting plate 7, and the suction pipe 9 is threadedly connected to the connecting sleeve 13. That is, the suction pipe 9 is detachable, which facilitates installation and disassembly for subsequent maintenance. Furthermore, the end of the inlet end 11 facing away from the suction pipe 9 is a flared structure, that is, the working end of the suction pipe 9 (i.e., the inlet end 11) is a flared structure with a larger opening.

[0021] like Figure 2, 3 As shown, in a more detailed embodiment, the outer wall of the end of the suction tube 9 facing away from the inlet end 11 is also provided with a connecting thread section, and the hose 12 can be fixedly connected to the connector 14. The inner wall of the connector 14 has threads to cooperate with the connecting thread section to realize the detachable connection between the connector 14 and the suction tube 9.

[0022] like Figure 1 , 2 As shown, the mounting plate 7 includes a connecting section 15 fixedly connected to the mounting head 3 and a mounting section 16 fixedly connected to the connecting section 15. The mounting section 16 and the connecting section 15 have a bent structure and are located diagonally above the visual positioning device 5. The perforation 8 and the connecting sleeve 13 are provided on the mounting section 16. The bent structure can cover the visual positioning device 5 diagonally below, thus also playing a protective role to a certain extent.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
