Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack lithium battery PACK processing, in particular to a soft-pack lithium battery PACK epoxy board box pasting tool. Background Art

[0002] During the assembly process of soft-pack lithium battery PACK (lithium battery PACK generally refers to combined batteries, mainly refers to the processing and assembly of lithium battery packs), after the cells are assembled into modules by connecting them in series or in parallel, the battery modules need to be wrapped with insulating materials such as epoxy boards in order to fix the batteries and protection boards and avoid short circuits between the battery pack and the outer metal box. Currently, due to the wide variety of battery pack models and different packaging standards, it is impossible to produce a complete packaging box at one time, and it can only be assembled by manual splicing.

[0003] At present, epoxy board boxes are usually made by manually splicing each epoxy board on the desktop, sticking tape on the splicing of the epoxy board and then folding it into an open packaging box; there are also plane limit fixtures to align the epoxy boards and glue them, and then obtain the unfolded semi-finished products. Then, the epoxy boards on the four sides are bent and spliced ​​from the glue joints with the middle epoxy board as the base. Both methods require the epoxy boards to be spliced ​​into unfolded semi-finished products and then assembled into boxes. The operation is cumbersome and affects production efficiency. In addition, the gap between the epoxy boards is not easy to control after manual gluing. If the gap is too small, it is difficult to bend or deform after bending. If the gap is too large, it will be loose after bending into a box, which reduces the protection effect and affects the subsequent loading into the box. Although the plane limit fixture can control the gap size to a certain extent, it still needs to be glued twice. In addition, the versatility is poor. When there are many types of epoxy board boxes, multiple fixtures need to be made to match, which increases the production cost. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Such as Figures 1-5As shown in the figure, a sticking tool for epoxy board box of a soft-pack lithium battery PACK according to the present utility model has a symmetric main body, including two left and right bottom plates 1. A square notch is provided on the lower surface of the front end of the bottom plate 1. The clamp 7 is in a C shape, the upper half of its C shape is stuck in the square notch of the bottom plate 1 and fixed by screws, and there is a threaded hole at the middle position of the lower half of the C shape. The hand-tightening threaded rod 8 is installed in the threaded hole of the clamp 7. When the lower surfaces of the two bottom plates 1 are closely attached to the desktop, the upper half of the C shape of the clamp 7 does not contact the desktop 9 in the square notch. After the inner vertical surface of the clamp 7 is closely attached to the edge of the desktop 9, the hand-tightening threaded rod 8 can be tightened to fix the bottom plate 1 on the desktop 9, so that the two bottom plates 1 are kept parallel on the desktop 9, and the position can be adjusted after the hand-tightening threaded rod 8 is loosened.

[0024] On the upper surfaces of the two left and right bottom plates 1, there is a group of two aluminum profiles 2 arranged front and back. The sides of the two aluminum profiles 2 are in the same plane. There are multiple holes on the two left and right bottom plates 1 so that the rear aluminum profile 2 can be adjusted back and forth. There are slider nuts 3 in the front chute of the front aluminum profile 2 and the outer side chutes of the front and rear aluminum profiles 2. A movable clamping block 4 corresponds to the outside of each slider nut 3. The movable clamping block 4 is in an L shape, with a chamfer at the upper end, a groove is provided below the chamfer, an elastic rubber strip 5 is clamped in the groove, and there is a protrusion on the outer side of the lower half of the movable clamping block 4, and the width of the protrusion is equal to the width of the chute opening of the aluminum profile 2.

[0025] Through the above settings, the movable clamping block 4 can be stuck in the chute of the aluminum profile 2 without deviation and locked on the slider nut 3 by screws. When the screws are tightened, the movable clamping block 4 can be fixed on the outside of the aluminum profile 2, and a U-shaped gap equivalent to the thickness of the epoxy board 10 is formed above the aluminum profile 2. There is a chamfer on the inner side above the movable clamping block 4, and a circular groove is provided below the chamfer, and an elastic rubber strip 5 is embedded in the groove, so that the epoxy board 10 can be inserted into the U-shaped gap by fitting the side vertical surface of the aluminum profile 2 and pressing the elastic rubber strip 5. This enables the epoxy board 10 to be attached to the surface of the aluminum profile 2 under the elastic force of the elastic rubber strip 5 and contact the bottom surface of the movable clamping block 4 in the U-shaped gap to limit and fix the epoxy board 10. In addition, each movable clamping block 4 can be adjusted up and down independently along the chute of the aluminum profile 2 to adapt to epoxy boards 10 of different sizes and shapes.

[0026] Above the aluminum profile 2 is a cover plate 6, whose front and outer sides are respectively aligned with the fronts and sides of the two groups of aluminum profiles 2 arranged front and back. The upper surface is flat and parallel to the bottom plate 1 and the desktop 9, so that the epoxy board 10 can be horizontally placed on the upper surface.

[0027] In the left - right direction, the cover plate 6 is aligned with the outer edges of the two sets of aluminum profiles 2, and the width of the cover plate 6 is greater than that of the aluminum profiles 2; in the front - back direction, the front edge of the cover plate 6 is aligned with the front edge of the aluminum profiles 2, and the length of the cover plate 6 extends backward beyond the aluminum profiles 2.

[0028] During use, loosen the hand - tightened threaded rod 8, move the positions of the two base plates 1 parallelly until the width of the outer side surfaces of the two front - side aluminum profiles 2 is equal to the width of the epoxy board 10 to be pasted on the front side. Then, loosen the screws of the movable blocks 4 on the front side and the left - right outer side surfaces and move the movable blocks 4 up and down so that the height from the horizontal plane of the inner L - shaped part of the movable blocks 4 on the front and side surfaces to the upper surface of the cover plate 6 is equal to the height of the square or special - shaped epoxy board 10.

[0029] After adjustment, the epoxy board 10 can be inserted into the U - shaped gap between the movable block 4 and the aluminum profile 2 from above along the chamfer of the movable block 4 and is fixed by the elastic rubber strip 5. Then, place the top epoxy board 10 with the epoxy boards 10 placed on the front and side surfaces as a reference on the cover plate 6, and place the epoxy board 10 to be pasted behind the top epoxy board 10. Subsequently, use the tape 11 for positioning and pasting to obtain an epoxy board box with one movable side. After putting the battery cells in, paste the movable - side epoxy board 10 to complete the wrapping of the battery main body.

[0030] The above - mentioned are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made using the content of the specification of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
