[0061] After research, it was found that in the related technology, after the welding points on the two end faces of the lithium battery were polished, the debris generated by the polishing would accumulate in the clamping device 1, that is, the limiting ring 16 in the clamping hole 13 would contact the end face of the lithium battery to clamp the lithium battery, and the debris caused by the polishing head 233 polishing the welding points on the end face of the lithium battery would accumulate on the inner wall of the limiting ring 16. When the lithium battery is released, the accumulated debris would fall to the side where the limiting ring 16 contacts the lithium battery, causing the debris to affect the contact between the limiting ring 16 and the subsequent lithium battery, resulting in the inability to clamp the lithium battery. If the inner wall of the limiting ring 16 is directly changed to an inclined surface, the debris will still accumulate on the inclined surface. As the number of polished lithium batteries increases, the debris accumulated on the inclined surface will still fall to the side where the limiting ring 16 contacts the lithium battery, affecting the clamping of the lithium battery.

[0062] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0063] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0064] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0065] like Figure 1As shown, the embodiment of the present disclosure provides a lithium battery assembly grinding device, comprising: a pair of clamping devices 1, and a grinding device 2 corresponding to the clamping device 1; the clamping device 1 is suitable for clamping the lithium battery from its two end faces; the grinding device 2 is suitable for grinding the residual welding spots on the end faces of the lithium battery after the clamping device 1 clamps the lithium battery; wherein the grinding device 2 comprises: a grinding mechanism, a sleeve 21 and a scraping block 22; the scraping block 22 is rotatably connected to the sleeve 21, and the scraping block 22 The sleeve 21 is partially extended out; the grinding mechanism is suitable for contacting the end face of the lithium battery after extending into the clamping device 1 to grind the residual welding spot on the end face of the lithium battery, and when the grinding mechanism extends into the clamping device 1, the sleeve 21 is pushed to make the scraping block 22 contact with the clamping device 1, so that the scraping block 22 rotates upward, and after the grinding is completed, the scraping block 22 rotates downward to scrape off the debris generated by the grinding; the debris generated after grinding is completely scraped off, and the accumulation of debris is avoided, which causes the clamping device 1 to be unable to clamp the lithium battery.

[0066] Lithium batteries are cylindrical in shape.

[0067] In some embodiments, part of the sleeve 21 extends into the three-way joint 17 of the clamping device 1, and the sleeve 21 is slidably connected to the three-way joint 17; an annular groove 211 is provided on the inner wall of the sleeve 21 along the circumference of the sleeve 21, and the annular groove 211 is arranged near one end of the sleeve 21 located in the three-way joint 17; a spiral groove 212 is provided on the inner bottom surface of the annular groove 211; the two connecting ports on the upper part of the three-way joint 17 are in the same straight line, one of which is in the clamping hole 13, the size of the connecting port is larger than the inner diameter of the limiting ring 16, the end face of the connecting port contacts the side of the limiting ring 16 away from the lithium battery, and the sleeve 21 extends into the interior of the three-way joint 17 from the other connecting port in the same straight line; the three-way joint will move with the clamping block 12.

[0068] like Figure 2 As shown, in some embodiments, a through hole 213 is opened on the side wall of the sleeve 21, and the through hole 213 is located at the bottom of the sleeve 21. The debris scraped by the scraper block 22 will pass through the through hole 213 into the connecting port at the bottom of the three-way joint 17, and then enter the collection box through the hose.

[0069] In some embodiments, a first spring 214 is sleeved on the outer wall of the portion of the sleeve 21 extending out of the three-way joint 17, and a ring body can be set on the portion of the sleeve 21 outside the three-way joint 17. One end of the first spring 214 is connected to the ring body, and the other end is connected to the three-way joint 17; the sleeve 21 can be reset by the first spring 214.

[0070] like Figure 3As shown, in some embodiments, a limiting block 221 is provided on the bottom surface of the scraping block 22, the limiting block 221 is located in the annular groove 211, and a second spring 222 is provided between the limiting block 221 and the inner wall of the annular groove 211, that is, one end of the second spring 222 is connected to the limiting block 221, and the other end of the second spring 222 is in contact with the inner wall of the annular groove 211, so as to prevent the second spring 222 from affecting the movement of the scraping block 22, and the limiting block 221 can be tightened by the second spring 222 to prevent the scraping block 22 from detaching from the annular groove 211; A protrusion 224 is provided on the bottom surface of the limit block 221, and the protrusion 224 is arranged in the spiral groove 212; an arc block 223 is provided on the bottom surface of the scraper block 22, and the arc block 223 is closer to the end of the sleeve 21 located in the three-way joint 17 than the limit block 221; the bottom surface of the arc block 223 contacts the inner wall of the sleeve 21; in the initial state, the scraper block 22 is at the bottom of the sleeve 21, pushing the sleeve 21 to move toward the clamping hole 13, and the bottom surface of the scraper block 22 will contact the inner wall of the limit ring 16, and the end surface of the scraper block 22 extending out of the sleeve 21 will contact the inner wall of the limit ring 16. When the sleeve 21 contacts the limiting ring 16, the scraper block 22 contacts the end face of the lithium battery, and the arc block 223 contacts the limiting ring 16 before the sleeve 21. When the arc block 223 contacts the limiting ring 16, the scraper block 22 contacts the end face of the lithium battery. At this time, as the sleeve 21 continues to approach the limiting ring 16, the protrusion 224 moves upward along the spiral groove 212, driving the scraper block 22 to move upward. During the upward movement of the scraper block 22, the degree of compression of the second spring 222 gradually increases. When the sleeve 21 contacts the limiting ring 16, the scraper block 22 can be in the upper half of the sleeve 21, and the scraper block 22 passes the highest point of the inner wall of the sleeve 21, and the through hole 213 and the three The connecting port at the bottom of the through joint 17 is connected, and the edge of the through hole 213 is close to the edge of the scraper block 22, ensuring that the debris scraped off by the scraper block 22 can fall through the through hole 213. After the grinding is completed, the sleeve 21 is loosened, and the sleeve 21 is moved away from the clamping hole 13 by the first spring 214. The scraper block 22 moves downward by gravity and the fallen debris is scraped to the top surface of the scraper block 22, and then guided to the through hole 213, so that the debris falls into the collection box. After the grinding is completed, the sleeve 21 can be moved repeatedly, so that the scraper block 22 moves up and down repeatedly, ensuring that all the fallen debris is scraped off.

[0071] In some embodiments, the top surface of the scraper block 22 is a slope, and the connection position between the top surface of the scraper block 22 and the side wall is also a slope; when the scraper block 22 moves, the debris can be shoveled toward the slope of the top surface through the slope of the side wall, and the debris can be discharged toward the through hole 213 through the slope of the top surface. After passing through the through hole 213, the debris falls into the collection box. Since the scraper block 22 moves repeatedly during the scraping process, the moving scraper block 22 can prevent the debris from accumulating on the slope of the scraper block 22, thereby avoiding the residue of debris.

[0072] like Figure 4 As shown, in some embodiments, the grinding mechanism includes: a first slide rail 23, a first slider 231, a driving motor 232, a grinding head 233, a connecting column 234 and a push plate 235; the first slide rail 23 is arranged on the base 4, the first slider 231 is arranged on the first slide rail 23, and the first slider 231 is suitable for moving along the first slide rail 23; the driving motor 232 is arranged on the first slider 231, and the grinding head 233 is connected to the output shaft of the driving motor 232; the push plate 235 is connected to the housing of the driving motor 232 through a plurality of connecting columns 234, and the grinding head 233 passes through the push plate 235; a filling sleeve 236 is arranged on the side of the push plate 235 facing the sleeve 21, and the filling sleeve 236 is sleeved outside the grinding head 233; the first slider 231 can be driven to move by a motor or the like, and the moving direction of the first slider 231 is parallel to the axial direction of the lithium battery, so that the grinding head 233 can extend into the sleeve 21 and contact the end surface of the lithium battery , the driving motor 232 drives the grinding head 233 to rotate to grind the welding point; when grinding is needed, the first slider 231 will approach the clamping hole 13, the push plate 235 will contact the sleeve 21, and then push the sleeve 21 toward the clamping hole 13. During the pushing process, the first spring 214 is in a compressed state. When the grinding head 233 contacts the lithium battery, the sleeve 21 contacts the limit ring 16. At this time, the filling sleeve 236 enters the sleeve 21, and the filling sleeve 236 can grind the grinding head 233 with the inner wall of the sleeve 21 The gap between them is filled to prevent flying debris from flying out of the sleeve 21 when grinding the weld point. At this time, the filling sleeve 236 will not block the through hole 213, so as to prevent the filling sleeve 236 from hindering the debris from passing through the through hole 213, and the flying debris will fall after contacting the filling sleeve 236, and the fallen debris can still fall into the collection box through the through hole 213; the size of the grinding head 233 is smaller than the inner diameter of the limiting ring 16, so that the grinding head 233 can pass through the limiting ring 16 to contact the lithium battery, and it is convenient for the debris to fall after grinding.

[0073] like Figure 5As shown, in some embodiments, the clamping device 1 includes: a bracket 11 and a clamping block 12; the bracket 11 is arranged on the base 4; the clamping block 12 is slidably connected to the bracket 11, and the clamping block 12 is connected to the clamping cylinder; a clamping hole 13 is opened on the clamping block 12, and a limit ring 16 is circumferentially arranged on the inner wall of the clamping hole 13; the part of the clamping hole 13 close to the lithium battery is trumpet-shaped, that is, the closer to the lithium battery, the larger the size of the clamping hole 13; the trumpet-shaped clamping hole 13 can guide the lithium battery when the clamping block 12 approaches the lithium battery to ensure that the lithium battery can enter the clamping hole 13; the two clamping blocks 12 in a pair of clamping devices 1 can be driven by the same clamping cylinder, so that the two clamping blocks 12 can approach or move away synchronously, and when the two clamping blocks 12 approach, the lithium battery can be clamped by the limit ring 16, and the lithium battery can be loosened when the two clamping blocks 12 move away.

[0074] In some embodiments, the portion of the clamping hole 13 away from the lithium battery is connected to a three-way joint 17, two connecting ports in the three-way joint 17 are in the same straight line, and the third connecting port is at the bottom of the three-way joint 17. The connecting port is connected to the collection box through a hose, and the hose can ensure that the three-way joint 17 moves with the clamping block 12 when the clamping block 12 moves.

[0075] In some embodiments, a clamping cylinder 14 is provided on the bracket 11, and a clamping block 15 is connected to the clamping cylinder 14, and the clamping block 15 is located between the two clamping blocks 12; the bottom surface of the clamping block 15 is adapted to the outer wall of the lithium battery; after the lithium battery is clamped, the clamping cylinder 14 can drive the clamping block 15 to descend, and the clamping block 15 contacts the lithium battery to clamp the lithium battery to prevent the lithium battery from moving during the grinding process.

[0076] In some embodiments, a conveying device 3 is arranged between the polishing devices 2, and the conveying device 3 is arranged on a base 4; wherein the conveying device 3 includes: a conveyor belt 31; a plurality of support blocks 32 are arranged on the conveyor belt 31, and the support blocks 32 are suitable for placing lithium batteries; the top surface of the support block 32 is adapted to the shape of the outer wall of the lithium battery; the conveyor belt 31 can continuously transport the lithium batteries to between the two polishing devices 2, thereby improving the polishing efficiency of the lithium batteries; the adaptation of the support block 32 to the lithium battery can prevent the lithium battery from rolling.

[0077] like Figure 6As shown, in the initial state, the distance between the two clamping blocks 12 is greater than the length of the lithium battery, and the grinding head 233 is located outside the sleeve 21. When the lithium battery is transported between the two clamping blocks 12, the two clamping blocks 12 are close to each other and the lithium battery is clamped by the limiting ring 16. Then the first slider 231 approaches the clamping hole 13, and the grinding head 233 extends into the sleeve 21. The push plate 235 contacts the sleeve 21 to push the sleeve 21 toward the clamping hole 13. The scraper block 22 moves toward the clamping hole 13 as the sleeve 21 approaches. When the end face of the scraper block 22 contacts the lithium battery, the arc block 223 contacts the limiting ring 16. At this time, the grinding head 233 has not yet contacted the lithium battery. As the sleeve 21 continues to move, the protrusion 224 will move along the spiral groove 212, causing the scraper block 22 to move upward. When the sleeve 21 contacts the limiting ring 16, the grinding head 233 contacts the lithium battery. 2 can be in the upper part of the sleeve 21, and the filling sleeve 236 enters the sleeve 21 to fill the gap between the grinding head 233 and the sleeve 21, and the driving motor 232 drives the grinding head 233 to rotate to grind the lithium battery. The flying debris is blocked by the filling sleeve 236 to prevent the debris from flying out of the sleeve 21, and the blocked debris will fall through the through hole 213. After the grinding is completed, the first slider 231 moves away from the clamping hole 13, and the push plate 235 releases the sleeve 21. The sleeve 21 is moved away from the clamping hole 13 through the first spring 214. The scraper block 22 moves downward by gravity, etc., scrapes the fallen debris to the top surface of the scraper block 22, and then guides it to the through hole 213, so that the debris falls into the collection box. After the grinding is completed, the sleeve 21 can be moved repeatedly, so that the scraper block 22 repeatedly moves upward and downward to ensure that all the fallen debris is scraped off.

[0078] In at least one other embodiment, a working method of the above-mentioned lithium battery assembly grinding device is also provided, including: the grinding mechanism is extended into the clamping device 1 and contacts the end face of the lithium battery to grind the residual welding spot on the end face of the lithium battery, and when the grinding mechanism is extended into the clamping device 1, the sleeve 21 is pushed so that the scraping block 22 contacts the clamping device 1, and the scraping block 22 is rotated upward.
