Technical Field

The utility model belongs to the automatic check out test set field of laminate polymer battery especially relates to a novel anchor clamps board of test electric core performance, is applied to laminate polymer battery OCV test machine.

Background

In the manufacturing process of the battery cell, after the battery cell is aged at a high temperature, the voltage, the internal resistance and the k value of the battery cell are often tested, and the battery cell with high self-discharge potential safety hazard is picked out, namely the OCV test of the battery cell. The tray clamp of the existing OCV testing machine is usually provided with a tray corresponding to one type, and the electric core of the fixed type can be reused. However, for the production of new models, the model trays are idle before, the sizes of the corresponding feeding clamping grooves are changed, new tray requirements are generated, cost expenses are increased for enterprises undoubtedly, and financial burdens of the enterprises are increased.

Therefore, the prior art has problems and needs to be further improved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a novel clamp plate for testing the performance of an electric core, which has simple structure and convenient use and adjustment, can improve the utilization rate and the production efficiency of a tray, and has strong practicability. By adopting the novel clamp plate, the tray can be used for meeting the use requirements of various specifications of battery cores, and the utilization rate and the production efficiency of the tray can be improved.

In order to achieve the above purpose, the specific technical solution of the present invention is as follows:

a novel clamp plate for testing the performance of an electric core comprises a battery tray, wherein a positioning module and a sliding clamping groove are arranged on the battery tray, an adjustable feeding clamping groove is formed by the movement of the positioning module on the sliding clamping groove, and the feeding clamping groove is used for placing the electric core to be tested; the battery tray is also provided with a baffle plate which is configured at the edge of the battery tray.

Preferably, the blocking plate is arranged at one end of each feeding clamping groove.

Preferably, the battery tray comprises an upper supporting plate and a lower supporting plate, the inner side of the upper supporting plate and the inner side of the lower supporting plate are fixed through bolts, the upper supporting plate and the lower supporting plate are abutted to support sliding guide, and the upper supporting plate is used for placing a test battery core.

Preferably, the positioning module and the sliding clamping groove are located above and on the left side and the right side of the feeding clamping groove, and the edge of the positioning module is chamfered to ensure that the battery to be tested is prevented from being damaged.

Preferably, the sliding card slot is configured on the battery tray in the transverse direction and the longitudinal direction and is used for forming the width and the length of the feeding card slot.

According to the size of electric core, adjust the orientation module and the slip draw-in groove of above the draw-in groove and left and right sides, orientation module slides to suitable position on the slip draw-in groove, makes orientation module be located electric core utmost point ear both sides, and left and right sides orientation module is located electric core high intermediate position to make draw-in groove position fix, the elasticity is moderate. And placing the battery cell in the adjusted feeding card slot, and pushing the battery cell into an OCV testing machine to finish the test.

Compared with the prior art, the utility model has the advantages of:

if the battery core model is changed and the size is changed, the position of the positioning module on the sliding clamping groove can be properly adjusted, so that the position of the feeding clamping groove is fixed. The condition that the tray needs to be replaced again due to the change of the model of the battery cell is avoided, the utilization rate of the tray is improved, the production cost is reduced, a pair of battery trays can bear the use requirements of a plurality of battery cells, and the production efficiency is also improved.

Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 3, the upper supporting plate 6 and the lower supporting plate 7 jointly form a battery tray 2, the feeding clamping groove 1 is located on the battery tray 2, and the positioning module 3 and the sliding clamping groove 4 are located above and on the left and right sides of the feeding clamping groove 1, wherein the feeding clamping groove 1 is used for placing an electric core. When the OCV testing machine tests the battery cell, the size of the feeding card slot 1 on the battery tray 2 is adjusted according to the size of the battery cell. The battery core to be tested is placed in the feeding clamping groove 1, the top of the battery core is perpendicular to the baffle plate 5, the positioning modules 3 above the battery core are adjusted to move left and right on the sliding clamping groove 4, when the lower parts of the two positioning modules 3 support against the two sides of the positive and negative electrode lug positions of the battery core, the battery core is fixed on the sliding clamping groove 4, and the upper and lower positions of the feeding clamping groove 1 are fixed accordingly. Adjust the orientation module 3 of electric core left and right sides, make it reciprocate at sliding clamp 4, when orientation module 3 was located electric core length intermediate position, fix orientation module 3 on sliding clamp 4, the position is also fixed thereupon about material loading draw-in groove 1.

The utility model discloses in, the inboard bolt fastening of

preferred bottom plate

6, 7, the butt is used for supporting the sliding guide between

bottom plate

6, 7, and top plate 6 is used for placing test electricity core.

If test electric core model specification change, need not change battery tray 2, can directly adjust the size of material loading draw-in groove 1 on the battery tray 2 through orientation module 3 and the mutual combination of slip draw-in groove 4, reach the multi-purpose of a dish, improve the utilization ratio of anchor clamps board, reduced newly-increased battery tray 2's expenditure, reduced manufacturing cost, improved production efficiency.
