Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a multi-station welding device. Background Art

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 3As shown, the multi-station welding device provided in the embodiment of the present application comprises a frame 1, a welding mechanism 2 arranged on the frame 1, and a plurality of conveying mechanisms 3 arranged on the frame 1 along the circumference of the welding mechanism 2, such as Figure 2 and Figure 4 As shown, the conveying mechanism 3 includes a mounting frame 31 fixedly arranged on the frame 1, a loading platform 32 slidably arranged on the mounting frame 31, and a No. 2 driving component 33 for driving the loading platform 32 to move horizontally. The loading platform 32 includes a chuck 321, a moving plate 322 driven by the No. 2 driving component 33, a lifting frame 323 vertically slidably connected to the moving plate 322, a No. 1 driving component 324 fixedly arranged on the moving plate 322 for driving the lifting frame 323 to rise and fall, and a rotating driving component 325 arranged on the lifting frame 323 for driving the chuck 321 to rotate. The welding mechanism 2 includes a multi-axis robot arm arranged on the frame 1 and a welding machine arranged on the multi-axis robot arm.

[0019] In actual use, the product is placed on the loading platform 32 of the corresponding conveying mechanism 3, specifically the No. 1 driving component 324 drives the lifting component to rise, so that the chuck 321 fixes the product. The multi-axis robot drives the welding machine to the preset welding position, and then the No. 2 driving component 33 drives the moving plate 322 to move to the welding position set by the welding mechanism 2, and then the No. 1 driving component 324 drives the lifting component to rise to the preset height, and then the rotating driving component 325 drives the chuck 321 to drive the product to rotate, and the welding machine welds the product. After the welding is completed, the rotating driving component 325 stops rotating the chuck 321, and the No. 2 driving component 33 drives the moving plate 322 to move to the unloading position.

[0020] In the above design, the welding mechanism 2 is used to alternately weld the products on the multiple conveying mechanisms 3, which can effectively improve the welding efficiency.

[0021] Specifically: Figure 4 As shown, the lifting frame 323 includes a plurality of linear bearings 231 vertically arranged on the moving plate 322, a plurality of guide columns 232 respectively sleeved on the linear bearings 231, and a mounting plate 233 connecting the upper ends of the plurality of guide columns 232, and the rotating drive assembly 325 is arranged on the mounting plate 233.

[0022] In actual use, when the lifting frame 323 is driven by the first driving assembly 324, the guide column 232 is lifted or lowered relative to the linear bearing 231, driving the mounting plate 233 to lift or lower.

[0023] In the above design, the structural design and specific implementation method of the lifting frame 323 can effectively achieve the stability of the lifting process.

[0024] Specifically: Figure 4As shown, the second driving assembly 33 includes a rack 331 horizontally arranged on the mounting frame 31, a motor 332 vertically arranged on the moving plate 322, and a gear 333 coaxially fixed on the output shaft of the motor 332, and the gear 333 is meshed with the rack 331.

[0025] In actual use, the first motor 332 drives the first gear 333 to rotate, so that the first gear 333 and the rack 331 mesh in and out, thereby driving the moving plate 322 to move along the extension direction of the rack 331.

[0026] In the above design, the structural design of the second driving assembly 33 facilitates ensuring the stability of the moving plate 322 when the moving plate 322 is driven.

[0027] Specifically: Figure 4 As shown, at least one driven meshing assembly is also disposed on the moving plate 322 , and the driven meshing assembly includes a rotating shaft 334 vertically rotatably disposed on the moving plate 322 , and a second gear 335 fixedly disposed at the lower end of the rotating shaft 334 and meshing with the rack 331 .

[0028] In actual use, during the movement of the moving plate 322 , the second gear 335 meshes with the rack 331 .

[0029] In the above design, the structural design of the driven engagement assembly can achieve stability during the movement of the moving plate 322 .

[0030] Specifically: Figure 2 As shown, the movable plate 322 is also provided with a No. 1 protective cover 4, and the upper end of the No. 1 protective cover 4 is provided with a No. 1 avoidance hole for avoiding welding, such as Figure 1 As shown, a No. 2 protective cover 5 is provided on the frame 1, the welding mechanism 2 is located in the No. 2 protective cover 5, the No. 2 protective cover 5 is provided with a plurality of No. 2 avoidance holes respectively used for avoiding the conveying mechanism 3, and the No. 2 protective cover 5 is provided with an exhaust pipe 6.

[0031] In the above design, the No. 1 protective cover 4 can effectively prevent the debris generated by welding from splashing to other positions of the conveying mechanism 3, and also prevent burns to the conveying mechanism 3. The structural design of the No. 2 protective cover 5 can protect the welding mechanism 2 from interference from external objects, and the exhaust pipe 6 can extract the smoke generated by welding in time.

[0032] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
