[0002] During the production and assembly of outdoor products, the welded parts often need to be ground to ensure a smooth and aesthetically pleasing surface. Weld point grinding is a common post-processing technique that is widely used in the manufacturing of metal products, frame structures, and various outdoor equipment.
[0003] An investigation revealed that a Chinese utility model patent discloses a semi-automatic solder joint grinding device for lithium batteries (publication number: CN215200473U), which includes a grinder and a displacement clamping mechanism for holding the lithium battery. The lithium battery cooperates with the grinder. The device also includes an angle adjustment mechanism for adjusting the angle of the grinder. The angle adjustment mechanism includes a grinder support column. One side of the grinder support column is provided with a vertical slider, a circumferential adjuster fixedly installed on the surface of the vertical slider, a grinder base fixedly installed on the outer surface of the circumferential adjuster, and a steering adjuster fixedly installed on the grinder base. The grinder is fixed to the upper end of the steering adjuster.
[0004] The aforementioned patent uses a displacement clamping mechanism to adjust the reciprocating motion of the lithium battery on the slide table under the grinder, which solves the problem of low efficiency when manually grinding the positive and negative terminals of lithium batteries.

[0025] Please see Figure 1-4 This utility model provides an automatic solder joint grinding device. Its core lies in the coordinated work of the spraying mechanism 3 and the displacement mechanism 2, combined with the functional design of the worktable 1, to achieve efficient, environmentally friendly and highly automated solder joint grinding operation. The specific embodiments of this utility model will be described in detail below with reference to the reference numerals in the accompanying drawings.
[0026] like Figures 1 to 4 As shown, the automatic weld point grinding equipment of this utility model mainly includes a worktable 1, a displacement mechanism 2, a spraying mechanism 3, and a grinding device. The worktable 1 serves as the basic structure of the entire equipment, used to place the workpiece and provide stable support. A filter screen 4 is embedded in the inner side of the top of the worktable 1, and a drain pipe 8 is provided at the bottom. The filter screen 4 and the drain pipe 8 work together to effectively collect and discharge the dust generated during the grinding process, thereby maintaining a clean working environment. A fixing plate 5 is also fixed on the top of the worktable 1. An electric push rod 6 is installed on one side of the fixing plate 5. The output end of the electric push rod 6 is connected to a clamping plate 7. The clamping plate 7 achieves the function of clamping and fixing the workpiece through the extension and retraction movement of the electric push rod 6. This design ensures that the workpiece remains stable during the grinding process, avoiding a decrease in grinding accuracy due to vibration or displacement.
[0027] The displacement mechanism 2 is located on the front side of the worktable 1 and is used to adjust the position of the grinding disc 10 to accommodate workpieces of different shapes and sizes. The displacement mechanism 2 consists of a first moving component, a second moving component, and a third moving component. The first moving component includes a fixed frame 21 welded to the front side of the worktable 1. A first servo motor 22 is provided on one side of the fixed frame 21. The first servo motor 22 drives the first lead screw 23 to rotate through a coupling. The first lead screw 23 is threadedly connected to the first moving plate 24. A guide rod 25 is slidably connected inside the first moving plate 24. The guide rod 25 is fixed inside the fixed frame 21 and is arranged parallel to the first lead screw 23. When the first moving plate 24 moves horizontally along the first lead screw 23, the guide rod 25 ensures that its movement trajectory is smooth and avoids deviation.
[0028] The second moving component includes a support frame 26 fixed to the top of the first moving plate 24. A second servo motor 27 is provided on the top of the support frame 26. The second servo motor 27 drives the second lead screw 28 to rotate through a coupling. The second lead screw 28 is threadedly connected to the second moving plate 29. A first limiting block 210 is provided on the outside of the second moving plate 29. The first limiting block 210 matches the first limiting groove inside the support frame 26. This design ensures that the second moving plate 29 will not deviate when it moves vertically along the second lead screw 28, and at the same time improves the accuracy of the movement.
[0029] The third moving component includes a lifting frame fixed to the rear side of the second moving plate 29. A third servo motor 211 is provided on the rear side of the lifting frame. The third servo motor 211 drives the third lead screw 212 to rotate through a coupling. The third lead screw 212 is threadedly connected to the third moving block 213. A second limiting block 214 is provided on the outer side of the third moving block 213. The second limiting block 214 matches the second limiting groove inside the lifting frame. This multi-layer displacement design realizes the multi-degree-of-freedom adjustment of the grinding disc 10 in the horizontal, vertical and height directions, which significantly improves the applicability of the equipment.
[0030] The spraying mechanism 3 is located outside the third moving component and is used to reduce dust and cool the grinding area. The spraying mechanism 3 includes a water tank 31, a pump body 32, a spiral hose 33, a connecting pipe 36, a diversion ring 35, and nozzles 37. The water tank 31 is located outside the displacement mechanism 2 and is used to store spraying water. The pump body 32 is fixed to the bottom of the water tank 31 and delivers water to the connecting pipe 36 through the spiral hose 33. The connecting pipe 36 is connected to the diversion ring 35. The diversion ring 35 is located above the grinding disc 10 and its diameter is larger than that of the grinding disc 10. It has a diversion groove inside and multiple inclined nozzles 37 are fixed on the inner wall of the diversion groove. The number of nozzles 37 is multiple and evenly distributed to ensure that the water can evenly cover the grinding area and the surface of the grinding disc 10. The diversion ring 35 is connected to the bottom of the third moving component through a fixing rod 34. The length and position of the fixing rod 34 are designed so that the spraying mechanism 3 and the grinding disc 10 can move synchronously under the drive of the displacement mechanism 2.
[0031] The working principle of the spraying mechanism 3 is as follows: When the pump body 32 is started, water is drawn from the water tank 31 and transported to the connecting pipe 36 through the spiral hose 33. Then, the water is diverted to the diversion ring 35 by the connecting pipe 36. The nozzles 37 in the diversion ring 35 spray water evenly onto the grinding area and the surface of the grinding disc 10 at an inclined angle, thereby achieving the effects of dust reduction and cooling.
[0032] The grinding device includes a grinding motor 9, a connecting shaft, and a grinding disc 10. The grinding motor 9 is fixed at the bottom of the third moving component and connected to the connecting shaft via a coupling. The grinding disc 10 is fixed at the bottom of the connecting shaft. The grinding motor 9 drives the grinding disc 10 to rotate via the connecting shaft, thereby grinding the surface of the workpiece. The rotation speed and force of the grinding disc 10 can be adjusted according to actual needs to meet the grinding requirements of different workpieces.
[0033] The specific operation process of this utility model is as follows: The outdoor product processing part after welding is placed on the workbench 1. The electric push rod 6 is started. The output end of the electric push rod 6 pushes the clamping plate 7 to move. The clamping plate 7 and the fixed plate 5 work together to clamp the outdoor product processing part. The displacement mechanism 2 is started. The first servo motor 22 drives the first lead screw 23 to rotate, which drives the first moving plate 24 to move horizontally along the guide rod 25 and adjusts the horizontal position of the grinding disc 10. The second servo motor 27 drives the second lead screw 28 to rotate, which drives the second moving plate 29 to move vertically along the first limiting groove and adjusts the vertical position of the grinding disc 10. The third servo motor 211 drives the third lead screw 212 to rotate, which drives the third moving block 213 moves up and down along the second limiting groove to adjust the height of the grinding disc 10, starts the spraying mechanism 3, the pump body 32 draws water from the water tank 31, delivers it to the connecting pipe 36 through the spiral hose 33, and then the water is diverted to the diversion ring 35 through the connecting pipe 36. The nozzles 37 in the diversion ring 35 spray water evenly at an inclined angle onto the grinding area and the surface of the grinding disc 10. The grinding motor 9 is started, and the grinding motor 9 drives the grinding disc 10 to rotate through the connecting shaft to grind the surface of the workpiece. The dust generated during the grinding process is moistened and settled by the water sprayed by the spraying mechanism 3. The settled dust is filtered through the filter screen 4 on the top of the workbench 1, enters the interior of the workbench 1, and is discharged through the drain pipe 8.
[0034] The practical application scenarios of this utility model include, but are not limited to, metal product processing, frame structure manufacturing, and outdoor equipment production. For example, in the process of outdoor equipment processing, the operator first places the outdoor equipment to be processed on the workbench 1 and fixes it with the electric push rod 6 and clamp 7. Then, the position of the grinding disc 10 is adjusted by the displacement mechanism 2 so that it is aligned with the welding point area of the outdoor equipment. After the spraying mechanism 3 is started, water is evenly sprayed from the nozzle 37 onto the grinding area and the surface of the grinding disc 10 to ensure that the dust generated during the grinding process is quickly moistened and settled. At the same time, the grinding motor 9 drives the grinding disc 10 to rotate at high speed to efficiently grind the welding point area. After the grinding is completed, the settled dust is collected through the filter screen 4 and discharged through the drain pipe 8, thereby maintaining the cleanliness of the working environment.
