Description

Technical Field

[0001] The utility model relates to the technical field of welding hole identification and positioning, in particular to a welding hole identification and positioning device for component welding. Background Art

[0002] Automatic welding production lines are commonly used equipment in the processing of automotive parts. They mainly use automatic loading and unloading robots to load and unload automotive parts, and then use automatic welding equipment to weld the automotive parts. The positioning of weld holes mainly relies on industrial cameras to photograph the parts, and then industrial software is used to identify and locate the weld holes in the photos. This is efficient and accurate. In order to better photograph the parts, industrial cameras are often set up above the welding area to ensure that the welding surface can be fully photographed, and then the weld holes are accurately identified and located. However, this design often causes the welding equipment's welding gun to be set at an angle to avoid the industrial camera. For special welding parts (when the weld holes are arranged vertically), welding cannot be performed well. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a welding hole identification and positioning device for component welding, comprising an industrial camera 2, a mounting plate 1 fixedly mounted on the top of the industrial camera 2, and an adjustment mechanism 3 provided on the outside of the mounting plate 1;

[0022] The adjusting mechanism 3 includes a mounting frame 301, a base component 303 is provided at the bottom of the mounting frame 301, a slide groove 302 is provided on the side of the mounting frame 301, and a limit frame 307 is provided for sliding inside the slide groove 302. A servo motor 304 and a reducer 305 are fixedly installed on the top of the mounting frame 301. The output end of the servo motor 304 is fixedly connected to the input end of the reducer 305. The output end of the reducer 305 is fixedly installed with a screw rod 1 306. The outer wall of the screw rod 1 306 is threadedly connected to the inner wall of the limit frame 307. The installation plate mounting plate 1 is slidably set in the limit frame 307. The inner wall of the limit frame 307 is rotatably connected with a screw rod 2 308 through a bearing. The installation plate mounting plate 1 is threadedly sleeved on the screw rod 2 308. The outer wall of the screw rod 2 308 is fixedly installed with a gear 309. The gear 309 is meshed with a rack 3010. The rack 3010 is fixedly installed on the outer wall of the mounting frame 301 and the mounting plate is mounted through the base component 303. The frame 301 is connected to the welding equipment. When shooting is required, the power of the servo motor 304 is transmitted to the screw rod 1 306 through the reducer 305, so that the screw rod 1 306 rotates, thereby driving the limit frame 307 to move downward. When the limit frame 307 moves downward, it drives the screw rod 2 308 to move downward, thereby driving the gear 309 to move downward, so that the rack 3010 pushes the gear 309 to rotate, thereby driving the screw rod 2 308 to rotate, so that the plate mounting plate 1 moves to the left and extends to the top of the welding equipment workbench and between the welding head directly above. The industrial camera 2 is turned on to shoot the parts and identify and locate the welding holes. Then the servo motor 304 is turned on to reverse, so that the plate mounting plate 1 is reset. Because when the plate mounting plate 1 is retracted into the limit frame 307, the height of the plate mounting plate 1 is high and will not hinder the loading and unloading robot from loading and unloading automobile parts. In addition, because the right movement is staggered with the welding head, it does not hinder the welding head from welding the vertically arranged welding holes.

[0023] The base component 303 includes a connecting plate 3031 and an L-shaped mounting seat 3032. The connecting plate 3031 is fixedly mounted on the bottom of the mounting frame 301. Threaded holes are provided on the left side surface and the top of the L-shaped mounting seat 3032. Threaded holes are provided at the four corners of the connecting plate 3031. The connecting plate 3031 is fixedly connected to the L-shaped mounting seat 3032 by bolts. The use of bolts to connect the L-shaped mounting seat 3032 and welding equipment facilitates the disassembly and assembly of the L-shaped mounting seat 3032. Similarly, the use of bolts to connect the L-shaped mounting seat 3032 and the connecting plate 3031 also facilitates the disassembly and assembly of the connecting plate 3031.

[0024] An electrical box 4 is fixedly installed on the top of the mounting frame 301. A drag chain 5 is provided on the left side of the electrical box 4. The end of the drag chain 5 away from the electrical box 4 is fixedly connected to the mounting plate 1 of the installation plate. The electrical box 4 is electrically connected to the industrial camera 2 through a cable, and the cable connecting the industrial camera 2 and the electrical box 4 passes through the drag chain 5. The drag chain 5 is provided to protect and guide the cables connecting the electrical box 4 and the industrial camera 2 to prevent the cables from becoming tangled during the position adjustment of the industrial camera 2.

[0025] A fill light 6 is fixedly installed on the lower surface of the industrial camera 2. The industrial camera 2 is close to the left end of the safety board mounting plate 1. The fill light 6 is provided to assist the industrial camera 2 in shooting. The industrial camera 2 is arranged at a position close to the left end of the safety board mounting plate 1 so that the industrial camera 2 can be more quickly extended above the welding equipment workbench.

[0026] The length of the rack 3010 is consistent with the length of the slide 302, and the rack 3010 is aligned with the slide 302, so that the gear 309 can always be engaged with the rack 3010 during the process of the limit frame 307 sliding up and down along the slide 302;

[0027] There are ten rows of threaded holes on the top of the L-shaped mounting base 3032, and they are evenly spaced on the L-shaped mounting base 3032. After the L-shaped mounting base 3032 is installed on the welding equipment, the connecting plate 3031 can be connected by selecting threaded holes in different positions to adjust the distance between the mounting frame 301 and the welding equipment, thereby ensuring that when the industrial camera 2 is extended above the workbench of the welding equipment, the mounting plate 1 is located directly below the welding head above.

[0028] Working principle: When in use, use bolts to install the L-shaped mounting base 3032 on the welding equipment, select the threaded holes in the appropriate position to install the connecting plate 3031, and after the loading robot places the parts on the welding equipment workbench, turn on the servo motor 304, and the reducer 305 transmits the power of the servo motor 304 to the screw rod 1 306, so that the screw rod 1 306 rotates, thereby driving the limit frame 307 to move downward, and when the limit frame 307 moves downward, it drives the screw rod 2 308 to move downward, and then drives the gear 309 to move downward, so that the rack 3010 pushes the gear 309 to rotate, and then drives the screw rod 2 308 to rotate, so that the safety plate mounting plate 1 moves to the left, extending to the top of the welding equipment workbench and between the welding head directly above, turn on the industrial camera 2 to shoot the parts, identify and locate the welding holes, and then turn on the servo motor 304 to reverse, so that the safety plate mounting plate 1 is reset.

[0029] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
