[0001] This utility model relates to the field of cabinet welding technology, and in particular to a cabinet back panel welding device. Background Technology

[0002] During the production and processing of the cabinet, the side panels on each side need to be welded. However, due to the special location of the back panel, it is difficult to position the back panel during welding, which affects the welding efficiency and quality of the back panel and the production progress of the cabinet. Therefore, there is an urgent need for a cabinet back panel welding device to solve this technical problem. Utility Model Content

[0003] The purpose of this utility model is to provide a cabinet back panel welding device in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A cabinet back panel welding device includes a welding robot. A support and limiting mechanism for limiting and supporting the cabinet and back panel is provided on the front side of the welding robot. The support and limiting mechanism includes a fixed frame, a rotating support assembly on the fixed frame, and an adjusting limiting assembly on the rotating support assembly. The rotating support assembly includes a support platform rotatably mounted on the fixed frame, with adjustment holes spaced apart on the support platform. The adjusting limiting assembly includes limiting posts inserted into the adjustment holes. Four limiting posts are rectangularly distributed, and reinforcing components connect adjacent limiting posts. The lower end of each limiting post is cylindrical, and the upper end is square. A flange is provided on the lower part of the outer wall of each limiting post. Through grooves are spaced apart longitudinally and laterally on the upper side of the flange, and horizontally arranged connecting posts are fixed within the through grooves.

[0006] Further details: The rotating support assembly also includes a rotating shaft fixed at the center of the lower end of the support platform. A worm gear is mounted on the rotating shaft, a worm is meshed on one side of the worm gear, and a servo motor is connected to one end of the worm.

[0007] Further configuration: Both the worm gear and the rotating shaft are rotatably connected to the fixed frame.

[0008] Further details: The reinforcement component includes a crossbar rotatably connected by a pin, a connecting hook movably connected to a connecting post, and a screw rod provided at one end of the connecting hook and the crossbar, with an internal threaded sleeve installed between the screw rods.

[0009] Further details: The reinforcement component includes a horizontally positioned internally threaded sleeve with screws connected to both ends of the sleeve, and a connecting hook fixed to the end of the screws away from the internally threaded sleeve.

[0010] Further configuration: The internal threaded sleeve is threadedly connected to the screw, and the threads on the screws on both sides of the internal threaded sleeve rotate in opposite directions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using a rotating support assembly and an adjusting limit assembly to support the limiting mechanism, the limiting posts of the adjusting limit assembly are positioned appropriately within the adjusting holes on the support platform. This ensures that the square posts on the upper side of the limiting posts align with the four corners of the inner wall of the cabinet. Then, a reinforcing assembly secures adjacent limiting posts, facilitating the placement of cabinets of different specifications on the flanges of the limiting posts. The cabinet back panel is then placed on top of the limiting posts. The rotating support assembly rotates the entire support platform, and a welding robot performs the welding, making it easier to weld and support the cabinet back panel, thus improving the efficiency and quality of the welding process.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, a cabinet back panel welding device includes a welding robot 1, and a support limiting mechanism is provided on the front side of the welding robot 1 for limiting and supporting the cabinet and back panel.

[0026] In this embodiment, the support limiting mechanism includes a fixed frame 21, a rotating support assembly on the fixed frame 21, and an adjustment limiting assembly on the rotating support assembly. The rotating support assembly includes a support platform 26 rotatably mounted on the fixed frame 21, with adjustment holes 261 spaced apart on the support platform 26. The rotating support assembly also includes a rotating shaft 22 fixed at the center of the lower end of the support platform 26. A worm gear 23 is mounted on the rotating shaft 22, and a worm 24 is meshed on one side of the worm gear 23. One end of the worm 24 is connected to a servo motor 25. Both the worm 24 and the rotating shaft 22 are rotatably connected to the fixed frame 21. The servo motor 25 drives the worm 24 to mesh and rotate with the worm gear 23, causing the rotating shaft 22 to drive the entire support platform 26 to rotate, which facilitates the rotational adjustment of the welding position of the cabinet.

[0027] The adjustment limiting component includes limiting posts 27 inserted into the adjustment holes 261. There are four rectangular limiting posts 27. Reinforcing components connect adjacent limiting posts 27. The lower end of the limiting post 27 is cylindrical and the upper end is square. A flange 271 is provided on the lower part of the outer wall of the limiting post 27. Through grooves 272 are provided longitudinally and laterally on the upper side of the flange 271. A horizontally arranged connecting post 273 is fixed in the through groove 272. By adjusting the limiting posts 27 to the appropriate position of the adjustment holes 261 on the support platform 26, the square post on the upper side of the limiting post 27 is aligned with the four corners of the inner wall of the cabinet. Then, the reinforcing components are used to fix the adjacent limiting posts 27, so that cabinets of different specifications and models can be placed on the flanges 271 of the limiting posts 27. Then, the cabinet back panel is placed on the upper end of the limiting posts 27 and welded.

[0028] The reinforcing component includes a crossbar 28 rotatably connected by a pin, and a connecting hook 29 movably connected to the connecting post 273. Both the connecting hook 29 and the crossbar 28 have screws 211 near their respective ends, and an internal threaded sleeve 210 is installed between the screws 211. Alternatively, the reinforcing component is a horizontally positioned internal threaded sleeve 210, with screws 211 connected to both ends of the internal threaded sleeve 210. A connecting hook 29 is fixed to the end of the screw 211 furthest from the internal threaded sleeve 210. The internal threaded sleeve 210 is threadedly connected to the screws 211, with the threads on the screws 211 on both sides of the internal threaded sleeve 210 rotating in opposite directions. By rotating the internal threaded sleeve 210, the extension length of the screws 211 on both sides of the internal threaded sleeve 210 is adjusted, allowing the connecting hooks 29 at both ends to hook onto the connecting post 273. Reversing the rotation of the internal threaded sleeve 210 tightens the screws 211, ensuring the stability of the positioning post 27.

[0029] The working principle and usage process of this utility model are as follows: Insert the lower end of the limiting post 27 into the adjustment hole 261 of the support platform 26, so that the square post on the upper side of the connecting post 273 is aligned with the four corners of the inner wall of the cabinet. Rotate the inner threaded sleeve 210 to adjust the extension length of the screws 211 on both sides of the inner threaded sleeve 210. Hook the connecting hooks 29 at both ends onto the connecting post 273. Then rotate the inner threaded sleeve 210 in the opposite direction to tighten the screws 211. Place the cabinet body downward on the flange 271 of the limiting post 27, and place the cabinet back plate on the upper end of the limiting post 27. Then, the welding robot 1 welds the back plate to the cabinet body. During the welding process, the servo motor 25 drives the worm gear 24 and worm wheel 23 to mesh and rotate, so that the rotating shaft 22 drives the support platform 26 to rotate as a whole, and the cabinet body is rotated and adjusted.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
