[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a robotic grinding and removal device for weld points on a carrier, comprising a worktable 1, which supports and positions the device. A robotic arm 5 is hinged to the left rear end of the upper surface of the worktable 1. Through the adjustment and control of the robotic arm 5, the device can remove weld points from carriers of different specifications, thereby improving the range of weld point removal for carriers of different specifications. A collection box 2 is fixedly connected to the lower surface of the worktable 1. The collection box 2 collects debris during the weld point removal process, improving the working environment of the device. A water tank 3 is fixedly connected to the rear surface of the collection box 2. A booster pump 4 is connected to the output pipe of the water tank 3. A barrier 8 is fixedly connected to the top corner of the outer wall of the worktable 1. The barrier 8 prevents debris from splashing during the grinding and removal of weld points on the carrier, improving the protection of the operator when using the device. A grinding component 6 is provided at the end of the robotic arm 5, and a collection component 7 is provided at the center of the upper surface of the worktable 1.

[0026] Reference Figure 2 - Figure 4When the robotic arm 5 is adjusted to the position of the carrier welding point, the grinding assembly 6 is activated. The grinding assembly 6 includes a grinder 61, which is detachably connected to the end of the robotic arm 5. A water tank 62 is fixedly connected to the right surface of the grinder 61, and a motor 63 is fixedly connected to the lower surface of the water tank 62. When the grinder 61 is activated, it drives the grinding disc 67 to rotate, grinding and polishing the raised welding point. The motor 63 is then activated, and its output shaft rotates, driving the gear disc 64 to rotate. The output shaft of the motor 63 is fixedly connected to the gear disc 64. The output pipe of the water tank 62 is connected to the water inlet of the grinder 61. A circular nozzle 65 is rotatably connected to the shaft center of the lower surface of the grinder 61. The booster pump 4 is activated, allowing water from the storage tank 3 to flow through the pipe and into the water tank 62 for grinding. In section 61, water is sprayed through the groove of the circular nozzle 65 to cool the grinding points of the carrier weld joints, improving the protection of the grinding component 6 during the grinding process. The water flow simultaneously discharges debris, improving the cleanliness of the grinding of the carrier weld joints. A gear 66 is rotatably connected to the groove on the outer wall of the circular nozzle 65. The teeth on the outer surface of the gear disc 64 mesh with the teeth of the gear 66. A grinding disc 67 is detachably connected to the axis of the circular nozzle 65, causing the gear 66 to rotate outside the circular nozzle 65. A baffle 68 is detachably connected to the lower surface of the gear 66, driving the baffle 68 to rotate. This allows the grinding disc 67 to isolate and block the flying debris generated during the grinding of the carrier weld joints, enhancing the grinding and removal effect of the equipment on the carrier weld joints.

[0027] Reference Figure 2 and Figure 5 During the grinding of the weld points on the carrier, the collection assembly 7 is activated. The collection assembly 7 includes a filter plate 72, which is detachably connected to a groove on the upper surface of the workbench 1 by bolts 71. When maintenance is required, the collection assembly 7 can be removed by unscrewing the bolts 71. Clamps 75 are welded to both the left and right surfaces of the filter plate 72, and bolts 71 are detachably connected to the upper surface of the clamps 75. A slide bar 73 is slidably connected to a groove on the lower surface of the filter plate 72, which drives the filter screen 74 for disassembly. When the filter screen 74 is damaged, it can be quickly replaced. This improves the ease of installation and disassembly of the collection component 7. A filter screen 74 is fixedly connected to the lower surface of the slide bar 73. The filter screen 74 is a hollow arc-shaped structure with rounded corners at the top. The cooling effect of the water spray from the ring nozzle 65 allows the debris to be discharged into the filter plate 72. The filter screen 74 separates the debris from the water flow, allowing the debris to be collected within the filter screen 74. This prevents workers from being scratched by debris when cleaning the collection box 2, improving the convenience of maintenance and enhancing the ease of debris collection and cleaning of the collection component 7.

[0028] Working principle: When the robotic arm 5 is adjusted to the position of the carrier welding point, the grinding assembly 6 is started, and the grinding machine 61 is started. The grinding machine 61 drives the grinding disc 67 to rotate, grinding and polishing the raised welding point. The motor 63 is started, and the output shaft of the motor 63 rotates, driving the gear disc 64 to rotate, so that the gear 66 rotates outside the circular nozzle 65, driving the baffle 68 to rotate, so that the grinding disc 67 isolates and blocks the flying debris generated during the grinding of the carrier welding point, improving the protection of the grinding assembly 6 during the grinding process. The booster pump 4 is started, so that the water in the water storage tank 3 is delivered to the grinding machine 61 through the water supply tank 62 via the pipeline, and sprayed out through the groove of the circular nozzle 65 to cool the grinding point of the carrier welding point. During the water flow, the debris is discharged at the same time, improving the protection of the carrier. The equipment ensures cleanliness during weld point grinding, enhancing its effectiveness in removing weld points from the carrier. During the grinding process, the collection component 7 is activated, using the cooling effect of water spray from the circular nozzle 65 to discharge debris into the filter plate 72. The filter screen 74 separates the debris from the water flow, allowing the debris to be collected within the screen. This prevents workers from being scratched by debris while cleaning the collection box 2, improving the convenience of maintenance. When maintenance is required, the collection component 7 can be removed by unscrewing the bolts 71, and the filter screen 74 can be disassembled using the sliding bar 73. Damaged filter screen 74 can be quickly replaced, improving the ease of installation and disassembly of the collection component 7 and enhancing its convenience in debris collection and cleaning.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
