Description

A Lithium-ion battery soft package roll core inspection fixture

technical field

The utility model relates to a battery detection device, in particular to a lithium-ion battery soft-wrap core inspection jig.

Background technique

At present, in the production process of polymer lithium-ion batteries, there are high requirements on the position of the tab of the battery after winding. If the position of the tab deviates too much, it will not be accurately pressed into the sinking groove of the tab during packaging, which will affect the packaging. Therefore, each winding machine is required to be equipped with a winding core inspection jig for employees to check whether the position of the battery tab meets the process requirements, and the staff at the full inspection station inspects the width of the battery tab. , Whether the center distance of the tabs and the width of the battery cell conform to the process. Due to the large number of models and the large output, each model and each machine needs to be equipped with a jig. The number is too large, not only the cost is high, but also the location is difficult to manage.

Contents of the invention

The purpose of this utility model is to provide a lithium-ion battery soft package winding core inspection jig for the above problems.

The technical solution adopted by the utility model is: a lithium-ion battery soft package roll core inspection fixture, including a fixed bottom plate, a battery cell fixed limit plate, a battery cell movable limit plate, a negative pole lug positioning groove, and a positive pole lug positioning groove 1. The battery standard block, above the fixed bottom plate is provided with tab positioning holes arranged horizontally, and below the negative tab positioning slot and the positive tab positioning slot are provided tab insertion columns corresponding to the positions of the tab positioning holes, And plugged with the tab positioning hole, the left side of the fixed bottom plate is provided with a fixed limit plate positioning hole, and the fixed limit plate insertion column corresponding to the position of the fixed limit plate positioning hole is provided under the fixed limit plate of the battery cell. And it is plugged with the positioning hole of the fixed cell limit plate. The right side of the fixed bottom plate is provided with a horizontally arranged movable limit plate positioning hole. The limiting plate is plugged into the post, and is plugged into the positioning hole of the movable limiting plate.

The battery standard block has at least two or more specifications.

The cell fixing limiting plate is connected to the fixing bottom plate through screws.

Tab notches are provided on the negative tab positioning groove and the positive tab positioning slot.

A row of above and below the right side of the fixed bottom plate is provided with the positioning holes of the movable limiting plate.

The tab positioning holes are provided in two rows.

The contribution of the utility model is that it can quickly, conveniently and effectively check whether the positive and negative lug spacing, side distance, lug width and battery main body width of the battery meet the current production model process size requirements, and can greatly save the company's cost. Or when adding a new model, it is necessary to increase the production cost of the battery inspection jig, and because of the reduction in quantity, the corresponding space for the jig placement is saved, and the management of the tooling jig is refined.

detailed description

This fixture is a combined structure, so that both the lug positioning groove and the cell limit plate can be adjusted flexibly, and the cell standard block is added, so that when switching between different models, the corresponding cell can be quickly adjusted according to the cell standard block. Model battery inspection jig, and finally achieve the effect of saving cost and reducing the number of tooling jigs. Further description below: As shown in Figure 1 and Figure 2, the utility model includes a fixed bottom plate 1, a cell fixed limit plate 22, a cell movable limit plate 21, a negative pole ear positioning groove 23, a positive pole ear positioning groove 24, an electric core Core standard block 3, above the fixed bottom plate are provided with two rows of tab positioning holes 13 arranged horizontally, and below the negative tab positioning groove 23 and the positive tab positioning slot 24 are respectively provided with poles corresponding to the positions of the tab positioning holes. Ear plug-in posts, and plug into the tab positioning holes, two tab positioning hole plug-in posts are fixed below the negative tab positioning slot and the positive tab positioning slot, and are plugged into the tab positioning holes during use. The size specification of the standard block 3 sets the insertion position of the negative tab positioning slot and the positive tab positioning slot. Because there are two rows of tab positioning holes in the horizontal direction, the negative tab positioning slot and the positive tab positioning slot are inserted in different positions, so that Corresponds to the size specification of the battery standard block 3. Tab notches 241 are provided on the negative tab positioning groove 23 and the positive tab positioning slot 24 . The left sides of the two fixed bottom plates are provided with fixed limit plate positioning holes 12, and the fixed limit plate 22 is provided with a fixed limit plate plug-in column corresponding to the position of the fixed limit plate positioning holes, and is connected to the fixed cell. The positioning hole of the limit plate is plugged in. The cell fixed limit plate is connected to the fixed bottom plate through screws, so that this side can be positioned, and the cell movable limit plate on the other side on the right side can be easily adjusted to different positions to correspond to different positions. specification batteries.
