[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figures 1 to 5 As shown, the anti-sticking spot welding head includes a welding head 1, an anti-sticking head 2, and a mounting plate 3. The welding head 1 is fixedly mounted on the mounting plate 3, and the anti-sticking head 2 is elastically slidably mounted on the mounting plate 3 and sleeved around the welding head 1. By elastically mounting and sleeved around the welding head 1, the anti-sticking head 2 elastically presses the welding head 1 downwards after spot welding is completed. When the welding head 1 is removed from the adhesive film, the anti-sticking head 2 still presses the adhesive film, preventing the adhesive film from melting and sticking to the welding head 1 and moving with the welding head 1. This ensures the stability of the adhesive film during the spot welding process, improves the spot welding effect, and ensures the completion of the spot welding process.
[0032] In order for the welding head 1 to extend from the bottom of the anti-stick head 2, the anti-stick head 2 is provided with a through groove 4 relative to the size of the welding head 1. The through groove 4 ensures that the anti-stick head 2 can surround the welding head 1 to press and prevent the adhesive film from sticking, thus ensuring the stability of the adhesive film pressing.
[0033] To prevent damage to the welding head 1, a protective plate 5 is also included. The protective plate 5 is fixedly installed on the mounting plate 3, and its projection on the plane of the mounting plate 3 shields the main body of the welding head 1. The protective plate 5 effectively protects the welding head 1, preventing it from being damaged by impacts during operation.
[0034] During operation, the observer needs to check the welding status of welding head 1 from time to time. For this purpose, an observation window 6 is provided on the protective plate 5 relative to the position of welding head 1. The observation window 6 is set in a mesh shape. Through the mesh-shaped observation port, the operating status of welding head 1 can be observed through the protective plate 5, and welding abnormalities of welding head 1 can be detected in advance for prevention.
[0035] In this embodiment, the sliding connection is specifically achieved through the cooperation of the guide post 7 and the linear bearing with the mounting plate 3. The linear bearing is fixed on the mounting plate 3, and the guide post 7 passes through the linear bearing and is fixedly connected to the anti-stick head 2. The arrangement of the guide post 7 and the linear bearing ensures both smooth sliding of the anti-stick head 2 and stability of its linear sliding.
[0036] To save on the cost of telescopic devices, such as cylinders and electric cylinders, a spring 8 is also fitted around the guide column 7. One end of the spring 8 abuts against the anti-stick head 2, and the other end abuts against the linear bearing. By using the spring 8, the anti-stick head 2 is prevented from requiring additional power to slide, thus saving equipment costs while ensuring stable operation of the equipment.
[0037] like Figure 2As shown, the welding head 1 is fixed to the mounting plate 3 by a fixing plate 9. The fixing plate 9 has an adjusting bolt 10 on the side opposite to the welding head 1, and the adjusting bolt 10 is threadedly connected to the welding head 1. By setting the adjusting bolt 10, the specific position of the welding head 1 can be finely adjusted, which facilitates the adjustment of the angle and position of the welding head 1.
[0038] Because of the presence of the protective plate 5, it is necessary to remove the protective plate 5 every time the welding head 1 needs to be fine-tuned. To solve this problem of wasting manpower, an adjustment groove 11 is provided on the protective plate 5 relative to the position of the adjusting nut. With the setting of the adjustment groove 11, the position of the welding head 1 can be fine-tuned without removing the protective plate 5, thus improving the equipment maintenance cycle speed.
[0039] To improve the compatibility of the spot welding head, a lifting device S and a traversing device H are also included. The mounting plate 3 is fixed to the movable end of the lifting device S, and the fixed end of the lifting device S is fixed to the movable end of the traversing device H. The lifting device S and traversing device H enable the spot welding head to move on a plane. The lifting device S ensures that the welding head 1 can vertically detach from the welding position, providing movement space for the anti-stick head 2. In this embodiment, the lifting device S uses a combination of a telescopic cylinder and a guide column, and the traversing device H uses a servo module.
