Technical Field

[0001] The invention relates to a cleaning insert basket for a battery steel shell, belonging to the technical field of battery steel shell cleaning tools. Background Art

[0002] The battery cell, mainly the 18650 battery cell, mainly includes a steel shell, a battery cap and a filler (such as a lithium compound) in the steel shell. The quality of the steel shell (one end is closed, i.e., the negative electrode of the battery cell) used to place the lithium compound directly determines the quality of the entire battery cell. The steel shell needs to be cleaned uniformly before use to remove its internal impurities, avoid affecting the internal charge and discharge reaction, and reduce the self-discharge ratio. In the prior art, the steel shell cleaning method is to place a large number of steel shells in a stainless steel basket in a disordered manner and rotate them in one direction for cleaning. During the cleaning process, the friction and collision between the steel shell and the steel shell, and the steel shell and the stainless steel basket will produce a large amount of metal foreign matter. These metal foreign matter will destroy the charge and discharge reaction of the internal lithium compound. Therefore, a battery steel shell cleaning tool with better practical use effect is needed.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] like Figures 1 to 5 As shown: This embodiment discloses a cleaning basket for a battery steel shell, comprising a frame 1, a bottom plate 2 and frame columns 3 respectively connected to the frame 1 and the bottom plate 2 at both ends, the frame columns 3 are equivalent to the outer wall of the entire cleaning basket, the bottom plate 2 is provided with a plurality of partitions 5 with a circular cross-section, the partitions 5 include transverse partitions and longitudinal partitions, the transverse partitions are arranged in a transversely equidistant array, the longitudinal partitions are arranged in a longitudinally equidistant array, the spacing between the transverse partitions and the longitudinal partitions is equal and equal to the outer diameter of the battery steel shell.

[0024] A bottom plate through hole 21 is provided between the transverse partitions and the longitudinal partitions of the bottom plate 2. An anti-collision device for connecting the end of the battery steel shell is also provided on the side of the bottom plate through hole 21. The anti-collision device is preferably a spherical protrusion 22. The spherical protrusion 22 can prevent the bottom plate 2 from directly contacting the end of the battery steel shell to avoid collision. Moreover, the spherical protrusion 22 is basically in point contact with the end of the battery steel shell, so that there is a little gap between the end of the battery steel shell and the bottom plate 2, which is conducive to the cleaning liquid entering the interior of the battery steel shell.

[0025] In order to prevent the metal impurities in this embodiment from affecting the battery steel shell, the frame 1, bottom plate 2, frame column 3, and partition column 5 in this embodiment are preferably made of non-metallic materials. Since the battery steel shell needs to be cleaned in a high temperature environment and must not be corroded by the cleaning liquid, the frame 1, bottom plate 2, frame column 3, and partition column 5 in this embodiment are preferably made of PA66 + 20% glass fiber, which can ensure that it will not deform in an environment with a temperature of up to 120°C.

[0026] Specifically, the bottom plate through hole 21 is preferably a rounded rectangular hole, so that there will be a certain space between each rectangular hole and the partition column 5, and the space is used to accommodate the spherical protrusion 22. Therefore, there are four spherical protrusions 22, and the four spherical protrusions 22 are respectively arranged on the four sides of the rounded rectangular hole.

[0027] In order to further avoid friction between the steel shell and the present embodiment, the cross-section of the battery steel shell connection side of the frame column 3 of the present embodiment is preferably an arc shape.

[0028] In order to further enhance the rigidity and strength of the frame 1, in this embodiment, a plurality of parallel support rods 4 are further provided in the frame 1. Specifically, the support rods 4 are connected to the frame 1 in the following manner: the frame 1 is provided with a support rod connection hole 11, and a protrusion is provided at the end of the support rod 4, and the protrusion is inserted into the support rod connection hole 11 to achieve the connection between the support rod 4 and the frame 1. The support rod connection hole 11 is preferably a through hole.

[0029] In order to enhance the rigidity and strength of the bottom plate 2 , the present embodiment further provides a plurality of crisscrossing convex ribs 23 at the bottom of the bottom plate 2 (opposite to the partition column 5 ), and these convex ribs 23 are arranged between the bottom plate through holes 21 .

[0030] When in use, the battery cell steel shell is inserted between the four partition columns 5. If the battery cell steel shell is close to the frame 1, it is between three partition columns 5 and a frame column 3. The partition columns 5 and the frame column 3 can fix and isolate the battery cell steel shell to avoid friction between the steel shells and between the steel shells and the cleaning basket during cleaning to produce metal impurities.

[0031] Compared with the prior art, the present invention can complete the cleaning of multiple battery steel shells at one time, and ensure that metal impurities will not be generated due to friction between the steel shells and between the steel shells and the cleaning basket. The spherical protrusion 22 is basically in point contact with the end of the battery steel shell, so that there is a small gap between the end of the battery steel shell and the bottom plate 2, which is conducive to the cleaning liquid entering the interior of the battery steel shell.

[0032] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
