[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 3The utility model provides an embodiment of an industrial welding head structure, comprising a laser generating device 1, a lens mounting frame 4 fixedly connected to the right end of the laser generating device 1, a protective device 2 provided on the outside of the lens mounting frame 4, a support frame 5 fixedly connected to the lower end of the laser generating device 1, and a replacement device 3 fixedly connected to the inner side of the lens mounting frame 4;

[0035] The protective device 2 includes an elastic telescopic rod 201, and the upper and lower ends of the elastic telescopic rod 201 are respectively rotatably connected to a group of rotating shafts 202. The end of the outer rotating shaft 202 is fixedly connected to a protective cover 203, and the upper end of the inner surface of the protective cover 203 is fixedly connected to a drying plate 205. The drying plate 205 is a molecular sieve filter plate, so after the sponge pad 204 absorbs the moisture that may exist on the surface of the laser welding head 305, it can adsorb the moisture attached to it, thereby ensuring the dryness within its protection area. The upper inner surface of the protective cover 203 is fixedly connected to a sponge pad 204, which can provide buffering protection for it when the protective cover 203 blocks the laser welding head 305, thereby avoiding rigid collision between the laser welding head 305 and the protective cover 203.

[0036] The lower end of the lens mounting frame 4 is provided with multiple groups of mounting grooves, so that lenses of different specifications can be installed through the mounting grooves here. The upper end of the outer arc surface of the lens mounting frame 4 is provided with an arc-shaped groove, so that the protective cover 203 can be rotated and embedded here, and its position is limited. The front and rear ends of the lens mounting frame 4 are fixedly connected to the rotating shaft 202. The two groups of rotating shafts 202 are respectively located on the outside of the lens mounting frame 4 and the outside of the protective cover 203. The end of the protective cover 203 away from the lens mounting frame 4 is provided with a groove matching the right end of the lens mounting frame 4, so that when the protective cover 203 blocks the laser welding head 305, the two can maintain relatively close contact. The inner wall thickness of the protective cover 203 is less than the inner wall thickness of the lens mounting frame 4, so it can accommodate the laser welding head 305 on the inner side of the protective cover 203.

[0037] Reference Figure 4 、 Figure 5 as well as Figure 6 The replacement device 3 includes a connecting seat 303, an end of the connecting seat 303 away from the lens mounting frame 4 is fixedly connected to a rubber pad 301, a side of the connecting seat 303 away from the lens mounting frame 4 is fixedly connected to a clamping block 302, a clamping slot 304 is clamped on the outer arc surface of the clamping block 302, an air bag 306 is fixedly connected to the inner side of the clamping slot 304, and an end of the clamping slot 304 away from the clamping block 302 is fixedly connected to a laser welding head 305.

[0038] The outer arc surface of the connecting seat 303 is fixedly connected to the lens mounting frame 4. The rubber pad 301 is set to be annular, and its diameter is larger than the inner diameter of the connecting seat 303. Therefore, when it contacts the laser welding head 305, it can maintain the tightness of the connection between the two through the deformation caused by its own extrusion. The clamping block 302 is set as a T-shape as a whole, and the inner surface of the card slot 304 is provided with a T-shaped groove, so that the clamping block 302 can be embedded in the card slot 304. The card slot 304 is set as an arc as a whole, and the clamping block 302 is set as an arc as a whole. The interior of the airbag 306 is filled with inert gas. The airbag 306 itself is made of nylon and is coated with sealing paint inside, so it is not easy to cause surface damage when it is rubbed by the clamping block 302.

[0039] Working principle: When using this device, it needs to be installed in a designated area, and the protective cover 203 is pulled away from the laser generating device 1 according to specific usage requirements. At this time, the elastic telescopic rod 201 will extend accordingly, and the protective cover 203 can be pushed to rotate. At this time, the laser welding head 305 will be exposed. When the elastic telescopic rod 201 is rotated 90 degrees, its lower end will be aligned with the groove above the lens mounting frame 4. At this time, the elastic telescopic rod 201 can be loosened. At the same time, due to the elastic force of the elastic telescopic rod 201, the protective cover 203 will move downward and embed into the groove at the upper end of the lens mounting frame 4, thereby Its position is limited. At the same time, according to different working conditions of the laser equipment, the laser welding head 305 can be rotated after the equipment stops. At this time, the laser welding head 305 will drive the slot 304 to rotate. At this time, since the torsional force is greater than the sum of the friction between the slot 304 and the block 302 and the friction between the block 302 and the airbag 306, the block 302 and the slot 304 will be separated from each other, thereby completing the quick disassembly of the laser welding head 305. When installing different laser welding heads 305, you only need to twist the laser welding head 305 according to the opposite operating steps to complete the quick installation and connection.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
