Description

Technical Field

[0001] This utility model belongs to the field of polishing technology, specifically, it relates to an integrated machine for polishing and cleaning the outer surface of battery aluminum shells. Background Technology

[0002] Aluminum battery casings are one of the main packaging materials for lithium-ion batteries, primarily used for structural support and sealing of prismatic batteries. Compared to steel casings, their advantages lie in weight reduction (20%–40% lighter) and a higher safety factor.

[0003] Chinese utility model patent CN219542656U discloses a surface grinding and polishing device for processing aluminum battery shells, including a base, a processing table fixedly connected to the base, a hydraulic rod and a cylinder device fixedly connected inside the processing table, a placement plate fixedly connected to the telescopic end of the hydraulic rod, and a placement plate fixedly connected to the telescopic end of the cylinder device. The placement plate is in contact with the inner wall of the processing table, and two air rods are fixedly connected to the placement plate. Through the cooperation of a servo motor and the hydraulic rod, the aluminum shell can be flipped as the servo motor rotates. At the same time, the retraction of the hydraulic rod causes the telescopic end of the cylinder device to retract, thereby venting the gas in the cylinder device, extending the air rod, driving the scraper to move, and thus scraping away the debris on the placement plate without manual cleaning.

[0004] The aforementioned existing technology also has the following drawbacks: the aluminum battery casing needs to be polished before it is sealed, and it is not possible to polish all the outer surfaces of the aluminum casing automatically, resulting in low polishing efficiency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that the aluminum battery casing requires grinding on all four side walls and one bottom before sealing, and that grinding on all outer surfaces of the aluminum casing cannot be fully automated, resulting in low grinding efficiency, this utility model adopts the following technical solution.

[0007] A battery aluminum shell outer surface polishing and cleaning integrated machine includes a polishing table, support legs detachably connected to the four corners of the bottom of the polishing table, an L-shaped connecting bracket vertical plate fixedly connected to the upper end of the polishing table, a water collection tank provided at the upper end of the polishing table, a drain hole provided at the bottom inner side of the water collection tank, an external water pipe flushing the center of the water collection tank, and a polishing component installed on the polishing table, which can polish the outer wall and bottom of the aluminum shell.

[0008] Preferably, a fixing component is installed below the L-shaped connecting bracket, which can fix the aluminum shell.

[0009] Preferably, an adjustment component is installed on the L-shaped connecting bracket, which enables the fixing component to move up and down and to rotate.

[0010] Preferably, the adjustment assembly includes a first electric telescopic rod, a mounting bracket, and a first drive motor. The upper end of the L-shaped connecting bracket is detachably connected to the first electric telescopic rod. The telescopic end of the first electric telescopic rod passes through the cross plate of the L-shaped connecting bracket and is detachably connected to the mounting bracket. The first drive motor is detachably connected inside the mounting bracket, and the rotating end of the first drive motor passes through the mounting bracket.

[0011] Preferably, the fixing assembly includes a storage plate, a sliding rod, and a contact plate. The rotating end of the first drive motor is detachably connected to a connecting plate. Multiple storage plates are rotatably connected to the connecting plate by a torsion spring. A sliding rod is slidably connected inside each storage plate. A spring is provided inside each storage plate, which causes the sliding rod to extend outward. The end of the sliding rod is detachably connected to a contact plate. The multiple storage plates are connected to the connecting plate by the torsion spring, which causes the multiple storage plates to have an inward contraction force.

[0012] Preferably, the grinding assembly includes a sliding groove, a first grinding disc, a mounting plate, a second drive motor, a second electric telescopic rod, a second grinding disc, and a third drive motor. The upper end of the grinding table is provided with a sliding groove. The outer wall of the grinding table is detachably connected to the second electric telescopic rod. The telescopic end of the second electric telescopic rod is inserted into the sliding groove and is detachably connected to the mounting plate. The outer wall of the mounting plate is detachably connected to the second drive motor. The rotating end of the second drive motor passes through the mounting plate and is detachably connected to the first grinding disc. The bottom of the grinding table is detachably connected to the third drive motor. The rotating end of the third drive motor passes through the grinding table and is detachably connected to the second grinding disc. The second grinding disc is located at the center of the water collection tank.

[0013] Preferably, each contact plate has a roller rotatably connected to its end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The second drive motor in the grinding assembly rotates to drive the first grinding disc to rotate, thereby grinding the outer wall of the aluminum shell. The third drive motor rotates to drive the second grinding disc to rotate, thereby grinding the bottom of the aluminum shell. The extension and retraction of the second electric telescopic rod can adjust the position of the first grinding disc according to the size of the workpiece, thereby achieving the purpose of grinding the outer wall and bottom of the aluminum shell.

[0016] 2. Through the set adjustment and fixing components, the first electric telescopic rod can move the contact plate downward to insert into the interior of the aluminum shell and fix the aluminum shell. The rotation of the first drive motor drives multiple contact plates to rotate, thereby making the aluminum box rotate, so that it can be flipped over during grinding. The extension of the first electric telescopic rod allows multiple contact plates to be inserted into the interior of the aluminum shell. As it moves downward, each contact plate opens outward to contact the inner wall of the aluminum shell, and each sliding rod adaptively retracts. The spring setting ensures that each contact plate can contact the inner wall of the aluminum shell, thereby fixing the round or square aluminum shell. When fixing the square aluminum shell, the extension and contraction of each spring allows each rolling wheel to contact the inner wall of the square aluminum shell. The rolling wheel can reduce the friction between the contact plate and the inner wall of the aluminum shell. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0028] like Figure 1 The diagram shows a preferred embodiment of the present invention: a battery aluminum shell outer surface grinding and cleaning integrated machine. This embodiment includes a grinding table 100, with support legs 101 detachably connected to the four corners of the bottom of the grinding table 100. An L-shaped connecting bracket 102 is fixedly connected to the upper end of the grinding table 100, and multiple contact plates 200 are installed below the L-shaped connecting bracket 102. A water collection tank 103 is provided at the upper end of the grinding table 100, and a drain hole 104 is provided at the bottom inner side of the water collection tank 103. An external water pipe is used to flush the center of the water collection tank 103. In this embodiment, the outer surface of the aluminum shell is cleaned via the external water pipe, and the water is collected in the water collection tank 103 and discharged through the drain hole 104.

[0029] like Figure 2 As shown, this is a schematic diagram of the adjustment component structure in this embodiment. The upper end of the L-shaped connecting bracket 102 is detachably connected to a first electric telescopic rod 201. The telescopic end of the first electric telescopic rod 201 passes through the horizontal plate of the L-shaped connecting bracket 102 and is detachably connected to a mounting bracket 202. The interior of the mounting bracket 202 is detachably connected to a first drive motor 203. The rotating end of the first drive motor 203 passes through the mounting bracket 202. The first drive motor 203 rotates to drive multiple contact plates 200 to rotate. In this embodiment, the first electric telescopic rod 201 enables the contact plates 200 to move downwards and insert into the interior of the aluminum shell to fix the aluminum shell. The rotation of the first drive motor 203 drives multiple contact plates 200 to rotate, thereby enabling the aluminum box to rotate and thus flip over during polishing.

[0030] It is worth noting that the first electric telescopic rod 201, the mounting bracket 202 and the first drive motor 203 mentioned above are the adjustment components in this embodiment. The adjustment components include, but are not limited to, the first electric telescopic rod 201, the mounting bracket 202 and the first drive motor 203. Any component that can rotate the aluminum shell can be used in this embodiment.

[0031] like Figure 3 As shown, this is a schematic diagram of the fixed component structure in this embodiment. The rotating end of the first drive motor 203 is detachably connected to a connecting plate 206. Multiple storage plates 205 are rotatably connected to the connecting plate 206 via torsion springs. A sliding rod 204 is slidably connected inside each storage plate 205. A spring is installed inside each storage plate 205, causing the sliding rod 204 to extend outwards. The end of the sliding rod 204 is detachably connected to a contact plate 200. The torsion spring connection between the multiple storage plates 205 and the connecting plate 206 causes the multiple storage plates 205 to have an inward contraction force. A roller is rotatably connected to the end of each contact plate 200. In this embodiment, the first electric telescopic rod 201 extends to insert multiple contact plates 200 into the interior of the aluminum shell. As it moves downward, each contact plate 200 opens outward to contact the inner wall of the aluminum shell, and each sliding rod 204 adaptively retracts. The springs ensure that each contact plate 200 can contact the inner wall of the aluminum shell, thereby fixing the round or square aluminum shell. When fixing a square aluminum shell, the extension and retraction of each spring ensures that each rolling wheel 207 can contact the inner wall of the square aluminum shell. The rolling wheels 207 reduce the friction between the contact plate 200 and the inner wall of the aluminum shell.

[0032] It is worth noting that the aforementioned storage plate 205, sliding rod 204, and contact plate 200 are fixing components in this embodiment. Fixing components include, but are not limited to, storage plate 205, sliding rod 204, and contact plate 200. Any component that can fix the aluminum shell can be applied to this embodiment.

A second electric telescopic rod 303 is detachably connected to the outer wall of the grinding table 100. The telescopic end of the second electric telescopic rod 303 is inserted into the sliding groove 105 and detachably connected to a mounting vertical plate 301. A second drive motor 302 is detachably connected to the outer wall of the mounting vertical plate 301. The rotating end of the second drive motor 302 passes through the mounting vertical plate 301 and is detachably connected to a first grinding disc 300. A third drive motor 305 is detachably connected to the bottom of the grinding table 100. The rotating end of the drive motor 305 passes through the grinding table 100 and is detachably connected to the second grinding disc 304. The second grinding disc 304 is located at the center of the water collection tank 103. In this embodiment, the rotation of the second drive motor 302 drives the first grinding disc 300 to rotate, thereby grinding the outer wall of the aluminum shell. The rotation of the third drive motor 305 drives the second grinding disc 304 to rotate, thereby grinding the bottom of the aluminum shell. The extension and retraction of the second electric telescopic rod 303 can adjust the position of the first grinding disc 300 according to the size of the workpiece, thereby achieving the purpose of grinding the outer wall and bottom of the aluminum shell.

[0034] It is worth noting that the aforementioned sliding groove 105, first grinding disc 300, mounting vertical plate 301, second drive motor 302, second electric telescopic rod 303, second grinding disc 304, and third drive motor 305 are the grinding components in this embodiment.
