Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a battery core processing edge grinding device. Background Art

[0002] With the development of science and technology, lithium batteries have been widely used in daily life and industrial production. As the core part of lithium batteries, the processing quality and efficiency of the battery cell directly affect the performance and cost of lithium batteries. During the processing of battery cells, nickel sheets are easily left at both ends of the battery cell. In order to improve the assembly accuracy and safety of the battery, the battery cell needs to be polished.

[0003] Traditionally, battery cell polishing is done by manually using a handheld polishing machine to directly polish the remaining nickel sheets at both ends of the battery cell. However, there is a certain risk as the workers' hands are close to the polishing sheets, and the polishing residues fly everywhere, which requires unified cleaning later, increasing the workload. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a battery core processing edge grinding device, which not only improves the safety during grinding and prevents workers' hands from getting close to the grinding disc, but also facilitates the unified collection of residues produced by grinding, which is clean and hygienic, and saves subsequent cleaning workload.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a battery cell edge grinding device, including a grinding motor, a rotating shaft is provided at the output end of the grinding motor, a grinding plate is provided at the top of the rotating shaft, a fixed sleeve is provided at one end of the grinding motor, a threaded sleeve is provided on the fixed sleeve, slag discharge pipes are provided on both sides of the sleeve, and a slag collecting box is provided on one side of the slag discharge pipe.

[0006] As an improvement, the grinding motor is handheld, and the grip of the grinding motor is wrapped with an anti-slip cover, which is convenient for holding and has strong overall stability.

[0007] As an improvement, the slag discharge pipe is obliquely arranged on both sides of the sleeve to facilitate the residues produced by grinding to fall directly into the slag collecting box.

[0008] As an improvement, a box door is provided on one side of the slag collecting box to facilitate pouring out the residue in the slag collecting box.

[0009] As an improvement, the bottom end of one side of the slag discharge pipe and the grinding sheet are at the same horizontal line, so that the residues produced by grinding can directly enter the slag discharge pipe.

[0010] As an improvement, the connection between the fixing sleeve and the grinding motor is a fixed connection, the connection is firm, and the whole is stable.

[0011] As an improvement, the length of the sleeve is smaller than the length of the battery cell, so that the battery cell can be easily taken out of the sleeve.

[0012] Compared with the prior art, the utility model has the advantages that the fixing sleeve and the sleeve can play a protective role, and because the battery core is located in the sleeve, the worker's hands are far away from the grinding sheet, which is highly safe. The residues and debris generated by grinding can be collected through the slag discharge pipe and the slag collection box to avoid scattering everywhere, thereby reducing the subsequent cleaning workload.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Combined with Figure 1 and attached Figure 2 A battery cell edge grinding device comprises a grinding motor 1, a rotating shaft 2 is provided at the output end of the grinding motor 1, a grinding sheet 3 is provided at the top of the rotating shaft 2, a fixing sleeve 4 is provided at one end of the grinding motor 1, a sleeve 5 with a threaded connection is provided on the fixing sleeve 4, slag discharge pipes 6 are provided on both sides of the sleeve 5, and a slag collecting box 7 is provided on one side of the slag discharge pipe 6.

[0020] Combined with Figure 4 The grinding motor 1 is handheld, which is convenient for grinding. The grip of the grinding motor 1 is wrapped with an anti-slip cover 9, which is stable as a whole.

[0021] Combined with Figure 2 In order to facilitate the discharge of the residues produced by grinding, the slag discharge pipe 6 is obliquely arranged on both sides of the sleeve 5.

[0022] Combined with Figure 3A box door 8 is provided on one side of the slag collecting box 7 to facilitate the removal of residues from the slag collecting box 7 and facilitate cleaning.

[0023] Combined with Figure 2 In order to facilitate the collection of the residues produced by grinding, the bottom end of one side of the slag discharge pipe 6 and the grinding sheet 3 are on the same horizontal line.

[0024] Combined with Figure 1 The connection between the fixing sleeve 4 and the grinding motor 1 is a fixed connection, which has a simple structure and a stable connection.

[0025] Combined with Figure 2 In order to facilitate the removal of the polished battery cell, the length of the sleeve 5 is smaller than the length of the battery cell.

[0026] During the specific implementation of the utility model, a worker holds the grinding motor 1 in one hand, presses the switch with his thumb, so that the sleeve 5 faces upward, and directly puts the battery cell to be ground into the sleeve 5 .

[0027] The grinding motor 1 is started, and the worker holds the battery cell with his other hand. The grinding motor 1 drives the shaft 2 to rotate continuously, and the grinding sheet 3 on the shaft 2 rotates accordingly. The grinding sheet 3 can grind the nickel sheet remaining at the bottom of the battery cell. Since the battery cell is located in the sleeve, the worker's hand is far away from the grinding sheet, which is highly safe.

[0028] The residues and debris generated by grinding can directly enter the slag collecting box 7 along the slag discharge pipe 6 and be collected uniformly to avoid scattering everywhere, thereby reducing the subsequent cleaning workload.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
