Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery core patch supporting device. Background Art

[0002] With the rapid economic development and the continuous growth of energy demand, in this context, lithium batteries, as an efficient and environmentally friendly energy storage technology, are receiving more and more attention and application. The top patch is an important component of lithium batteries. It needs to expose the positive and negative poles and the pressure relief valve while covering the aluminum shell. The angle and position deviation of the battery cell can make the top patch invalid.

[0003] like Figure 1 As shown, in the prior art, when the top patch is performed on the lithium battery, the battery cell 3' is usually arranged on the support base 1', but the upper end surface of the support base 1' is usually in contact with the lower end surface of the battery cell 3' as a whole. At this time, if the consistency of the bottom surface of the battery cell 3' is poor, that is, when the lower end surface of the battery cell 3' has a protrusion 101', the battery cell will be offset and tilted, so that the battery cell 3' deviates from the position set by the robot for patching. If the top patch is performed at this time, the patch may be invalid. Utility Model Content

[0026] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0028] refer to Figures 2 to 8 , the utility model embodiment discloses:

[0029] A battery cell patch support device comprises two support seats 1 with a preset spacing, and a support portion 2 arranged on each of the support seats 1, wherein the support portion 2 is used to support the edge position of the bottom of both sides of the battery cell 3 so that the middle of the bottom side of the battery cell 3 is suspended; Figure 3 Two support seats 1 are provided, and the two support seats 1 have a preset spacing, which is limited by the width of the battery cell 3, so that the support portion 2 of the support seat 1 supports the edge position of the bottom of both sides of the battery cell 3. At this time, the middle part of the bottom side of the battery cell 3 is suspended, thereby reducing the interference to the top patch caused by poor consistency of the lower end surface of the battery cell 3 (when the bottom of the battery cell 3 has an outward protrusion).

[0030] The battery cell 3 is arranged on the support base 1, and when the battery cell 3 is mounted, it may be offset to the left and right sides of the two support bases 1, so that the battery cell 3 and the patch position do not correspond to each other, thereby causing the patch to be invalid; therefore, refer to Figure 4 As a further improvement of the present embodiment, an anti-deflection portion 4 is provided on each of the two support seats 1, the distance between the two anti-deflection portions 4 is greater than the width of the battery cell 3, and the two anti-deflection portions 4 can abut against the side edges of the battery cell 3; an anti-deflection portion 4 is provided on the support seat 1, and the anti-deflection portion 4 can abut against the side wall of the battery cell 3, thereby preventing the battery cell 3 from deviating to the left and right sides of the two support seats 1.

[0031] However, if the consistency of the side wall of the battery cell 3 is also poor, that is, the side wall of the battery cell 3 also has an outer convexity, it is also possible that the battery cell 3 cannot be accurately installed on the support portion 2 of the two support seats 1, resulting in the battery cell 3 and the patch position not corresponding to each other, thereby causing the patch to be invalid; therefore, refer to Figure 5 As a further improvement of the present embodiment, an inclined anti-deflection surface 5 is provided on the side where the anti-deflection portion 4 is connected to the support portion 2, and the inclined anti-deflection surface 5 is inclined toward the direction away from the side wall of the battery cell 3; an inclined anti-deflection surface 5 is provided, and the inclined anti-deflection surface 5 will not directly contact the side wall of the battery cell 3 (specifically, it abuts against the side edge of the bottom of the battery cell 3), thereby avoiding interference of the side wall of the battery cell 3 to the patch, and at the same time, due to the inclined setting of the end face on the side where the anti-deflection portion 4 is connected to the support portion 2, the anti-deflection portion 4 can still prevent the battery cell 3 from deflecting (the battery cell 3 needs to be subjected to an external force to overcome the deflection of the inclined anti-deflection surface 5).

[0032] The inclined anti-deflection surface 5 has an inclination angle of 30°-60°, specifically 45° in this embodiment.

[0033] The support seat 1, the support portion 2 and the anti-deflection portion 4 are integrally formed, so as to facilitate processing.

[0034] In addition, a positioning device is also included, and the positioning device is used to limit the battery cell 3 to the position to be mounted on the support part 2 when installing the battery cell 3, such as Figure 6 As shown, when the battery cell 3 is installed (when the battery cell 3 is placed), the battery cell 3 itself may be offset, that is, the battery cell 3 is on the inclined anti-deflection surface 5 on one side and on the support portion 2 on the other side; through the positioning device, the battery cell 3 is confined on the support portions 2 of the two support seats 1, so that the battery cell 3 can be accurately mounted.

[0035] Specifically, the positioning device includes two positioning plates 6 that can be slidably arranged on both sides of the two support seats 1, and a driving mechanism 7 that is arranged on both sides of the two support seats 1 and is used to drive the positioning plates 6 to slide. The two positioning plates 6 slide simultaneously and relatively to each other to resist the side walls of the battery cells 3, wherein the driving mechanism 7 is a telescopic cylinder, and its output end is transmission-connected to the positioning plates 6; the positioning plates 6 can slide left and right relative to the support seat 1, thereby pushing the battery cells 3 to move, so that the lower end surfaces at both ends of the battery cells 3 can accurately cooperate with the support part 2.

[0036] like Figure 7 As shown, when the battery cell 3 is installed (when the battery cell 3 is placed), the battery cell 3 itself may be offset, that is, when one side of the battery cell 3 is on the inclined anti-deflection surface 5 and the other side is on the workbench for installing the support seat 1, that is, it is located between the two support seats 1; at this time, even if there is a positioning plate 6 pushing, the end surface of the end of the support portion 2 will limit the battery cell 3 from sliding toward the upper end surface of the support portion 2; therefore, refer to Figure 8As a further improvement of this embodiment, an inclined guide surface 8 is provided at the end of the support portion 2, and the distance between the inclined guide surfaces 8 at both ends gradually decreases from top to bottom. The inclined guide surface 8 is provided, and the positioning plate 6 pushes one side of the battery cell 3, and the other side of the battery cell 3 can slide along the inclined guide surface 8 to the upper end surface of the support portion 2; the inclination angle of the inclined guide surface 8 is 30°-60°, and specifically 45° in this embodiment.

[0037] The positioning plate 6 is provided with a rubber pad 9 , which can avoid direct hard contact between the positioning plate 6 and the battery cell 3 (during the contact process, the rubber pad 9 undergoes a certain degree of elastic deformation) to prevent the battery cell 3 from being damaged.

[0038] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
