[0025] like Figure 1 As shown, a battery copper sheet encapsulation jig includes a jig seat 10 and a positioning member 20, wherein:

[0026] The fixture seat 10 is a frame-shaped structure with an upper end opening, and is provided with a plurality of staggered partitions 11 therein, and the plurality of partitions 11 divide the interior of the fixture seat 10 into a plurality of cells 1, each of which can be matched with a battery copper sheet 30 and has a depth greater than the thickness of the battery copper sheet 30, and a plurality of vent grooves 2 are provided at the bottom of each cell 1, and each vent groove 2 passes through the bottom end of the fixture seat 10, and the plurality of vent grooves 2 in the same cell 1 are arranged at equal intervals in the direction in which the cell 1 extends;

[0027] The positioning member 20 can fix the battery copper sheet 30 installed in each unit cell 1 on the fixture seat 10 .

[0028] In one embodiment of the utility model, the positioning member 20 is a fastening positioning member, including a plurality of locking members 21 and a plurality of positioning hole grooves 22. The plurality of positioning hole grooves 22 are arranged on the bottom wall of each cell 1 and are matched one by one with the plurality of locking members 21. Each locking member 21 can pass through a battery copper sheet 30 and extend into a positioning hole groove 22 to press a battery copper sheet 30 against the fixture seat 10.

[0029] In this embodiment, each locking member 21 includes a screw rod 3 , each screw rod 3 is provided with a nut 4 , and each nut 4 can press a battery copper sheet 30 against the bottom inner wall of the fixture seat 10 .

[0030] In a further design, each positioning hole groove 22 is disposed between two vent grooves 2, and its depth is less than the wall thickness of the bottom of the fixture seat 10. To further ensure that the battery copper sheet 30 and the fixture seat 10 maintain the same flatness and thus ensure that the rubber coating thereon has the same thickness, each positioning hole groove 22 is disposed in the middle of two vent grooves 2.

[0031] This embodiment is suitable for battery copper sheets 30 with mounting holes and grooves. To avoid the glue from blocking these holes and grooves, after placing the battery copper sheet 30 in the cell 1, use the locking piece 21 to pass through the battery copper sheet 30 and extend into the large positioning hole 21, and press each battery copper sheet 30 flatly against the fixture seat 10; after the battery copper sheet 30 is fixed, the glue can be poured into each cell 1 and spread flat on the battery copper sheet 30. The gas is pushed out of the cell 1 by the glue or enters the vent groove 2 through the bottom of the battery copper sheet 30 and then discharged, which can avoid the undesirable phenomenon of bubbles or bubble holes in the glue package caused by gas retention. After the glue is poured, let it stand for the glue to solidify, remove the locking piece 21 and remove the glue-wrapped battery copper sheet 30 from the cell 1. If there is a burr formed by the overflow of glue at the bottom of the battery copper sheet 30, it can be removed through the subsequent de-wrapping process.

[0032] In another embodiment of the utility model, the positioning member 20 is a pneumatic positioning member, including an air suction pipe, one end of which is connected to a plurality of ventilation slots 2, and the other end is connected to an air pump. The air pump can extract the gas in each cell 1 to adsorb the battery copper sheet 30 installed therein onto the fixture seat 10.

[0033] In this embodiment, the air suction pipeline is arranged on a base 40, which is a frame-shaped structure with an open upper end and is matched with the outer periphery of the fixture seat 10. A plurality of positioning protrusions 41 that can support the fixture seat 10 are provided on the inner wall of the base 40, and a plurality of air holes 42 are provided between or on one side of the plurality of positioning protrusions 41. Each air hole 42 passes through the base 40 and is connected to an air pipe, and one end of the air pipe is connected to an air pump.

[0034] This embodiment is suitable for battery copper sheets 30 without mounting holes. In order to avoid or reduce the glue from overflowing to the bottom of the battery copper sheet 30, the battery copper sheet 30 is adsorbed on the fixture seat 10 by negative pressure absorption. During operation, firstly, part of the glue is poured into the cell 1 where the battery copper sheet 30 is placed, then the air pump is turned on at the right time to absorb the gas in the cell 1 and adsorb the battery copper sheet 30 on the fixture seat 10, and the glue is continued until the entire cell 1 is filled, and finally the air pump is turned off and the glue is left to solidify.

[0035] The utility model forms a plurality of cells 1 adapted to the battery copper sheets 30 on a jig seat 10, so as to facilitate the rubber encapsulation processing of a plurality of battery copper sheets 30 at the same time, with high processing efficiency, and the amount of glue injection is limited by the depth of the cell 1, so as to ensure that all products have a uniform rubber encapsulation thickness; and by arranging a vent groove 2 below the battery copper sheet 30 on the jig seat 10, a discharge passage is reserved for residual gas in the cell 1, so as to avoid bubbles or bubble holes on the rubber encapsulation caused by gas retention.

[0036] In some embodiments of the present invention, the rubber-coated jig further includes one or more scrapers 50 embedded in the jig seat 10, and the width of each scraper 50 is greater than the width of each cell 1; and one or more slots 12 are provided on the jig seat 10 beside a plurality of cells 1, and each slot 12 can accommodate one or more scrapers 50.

[0037] It can be understood that in order to further ensure that the rubber coating on the same battery copper sheet 30 has a consistent wall thickness, when the glue is filled, the scraper 50 can be used to scrape the upper end surface of the jig seat 10 to remove the glue that exceeds the contour or depth direction of the cell 1, thereby ensuring the dimensional accuracy of the rubber coating and the flatness of the surface; when the scraper 50 is not used or after use, it can be placed in the card slot 12, which is convenient to use.

[0038] In the above embodiment, the fixture seat 10 and the plurality of partitions 11 are integrally formed.

[0039] It can be understood that the one-piece structure is not only easy to process and produce without assembly, but also ensures that the structure of the fixture seat 10 is more stable, avoids the problem of deformation of the cell 1 when installing or using the positioning member 20, and ensures the dimensional accuracy of the rubber coating.

[0040] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
