Description

Technical Field

[0001] The present invention relates to the technical field of product packaging, and in particular to an auxiliary edge-closing device.

Background Art

[0002] Batteries can be widely used to power mobile devices. In order to increase the battery capacity or to match the structure of mobile devices, in actual production, several batteries often need to be combined. After the battery combination, it is then coated with Mylar (polyester film). Currently, in the workshop, when applying Mylar (polyester film) coating to products such as batteries, an edge-closing device needs to be used. As shown in Figure 1 The edge-closing device includes two profiling grooves A and B. The sizes of profiling grooves A and B are the same and are mirror-symmetrically arranged on the jig plate 1. First, the assembled batteries are manually placed into profiling groove A. Profiling groove A is designed according to the shape of the battery. Then, the packaging equipment attaches the Mylar (polyester film) to the battery. Then, the battery pack is taken out, flipped, and placed into profiling groove B. The edge of profiling groove B is used to perform side attachment, that is, edge-closing, on the Mylar (polyester film) attached to the battery. However, since it is difficult to ensure that the outer dimensions of each battery to be coated are absolutely uniform, it is easy to have poor fitting between the battery and profiling groove B, resulting in an unsatisfactory edge-closing situation.

[0003] In view of this, the present invention provides an auxiliary edge-closing device to solve the above problems.

Summary of the Invention

[0004] In order to solve the problem that when products to be coated with Mylar (polyester film) have non-uniform outer dimensions, it will result in poor edge-closing due to poor fitting when the products are placed in the existing edge-closing device for edge-closing, the present invention provides an auxiliary edge-closing device to solve the above problems.

[0005] The solution of the present invention to solve its technical problems is: an auxiliary edge-closing device, comprising:

[0006] A bottom plate, on which a first profiling groove and a second profiling groove are provided. The first profiling groove is designed according to the outer dimensions of the product. The second profiling groove is provided with an edge-closing structure, and the edge-closing structure includes:

[0007] A fixed block, which is fixed to the bottom plate. Guide sleeves are provided at both ends of the fixed block. A guide post is inserted into each guide sleeve. One end of the guide post is inserted into the guide sleeve and is restricted by the guide sleeve from passing through the guide sleeve. The other end of the guide post is sleeved with an elastic element and then fixed to a movable block. A limit pin is also provided in the middle of the movable block, and the limiting end of the limit pin is movably arranged in the limit hole in the middle of the fixed block.

[0008] Preferably, the edge trimming structure is provided on two sides adjacent to the second profiling groove.

[0009] Preferably, the limit pin is a T-shaped limit pin, and the limit hole is a T-shaped hole.

[0010] Preferably, the elastic element is a spring.

[0011] The beneficial effect of the present invention is that an auxiliary edge trimming device of the present invention enables elastic fine-tuning of the size of the second profiling groove by providing an edge trimming structure on the second profiling groove, so that the second profiling groove can better fit the side of the product, improving the edge trimming effect and enhancing the product quality.

Detailed Embodiments

[0016] To further elaborate on the technical means and effects adopted by the present invention, the following describes the present invention in detail in conjunction with the embodiments and the accompanying drawings of the present invention.

[0017] The present invention provides an auxiliary edge trimming device for assisting in side edge trimming of products such as batteries with Mylar (polyester film) attached. The auxiliary edge trimming device includes:

[0018] a bottom plate 2, on which a first profiling groove 20 and a second profiling groove 21 are provided. The first profiling groove 20 is designed according to the outer dimension of the product. The second profiling groove 21 is provided with an edge trimming structure 22, and the edge trimming structure 22 enables elastic fine-tuning of the size of the second profiling groove 21 relative to the size of the first profiling groove 20. The edge trimming structure 22 includes:

[0019] A fixed block 220 is fixed to the bottom plate 2. Guide sleeves 221 are provided at both ends of the fixed block 220. A guide post 222 is inserted into each guide sleeve 221. One end of the guide post 222 passes through the guide sleeve 221 and is restricted by the guide sleeve 221 from passing through the guide sleeve 221 again. The other end of the guide post 222 is sleeved with an elastic element 223 and then fixed to a movable block 224. A limit pin 225 is further provided in the middle of the movable block 224. The limiting end 226 of the limit pin 225 is movably arranged in a limit hole 227 in the middle of the fixed block 220.

[0020] Wherein, the edge folding structure 22 is arranged on two adjacent side edges of the second profiling groove 21.

[0021] Wherein, the limit pin 225 is a T-shaped limit pin, and the limit hole 227 is a T-shaped hole.

[0022] Wherein, the elastic element 223 is a spring.

[0023] The working process of the present invention is as follows: An operator first places a product to be wrapped with Mylar (polyester film), such as a battery, into the first profiling groove 20. The packaging equipment attaches the Mylar (polyester film) to the surface of the product. Then, the product is taken out, flipped, and placed into the second profiling groove 21. The edge folding structure 22 on the second profiling groove 21 will elastically fine-tune the size of the second profiling groove 21 according to the outer dimension of the product, so that the edge of the second profiling groove 21 closely fits the side of the product, thereby enabling the Mylar (polyester film) to fit well with the side of the product.

[0024] The beneficial effect of the present invention is that an auxiliary edge folding device of the present invention can elastically fine-tune the size of the second profiling groove 21 by arranging the edge folding structure 22 on the second profiling groove 21, so that the second profiling groove 21 can better fit the side of the product, improve the edge folding effect, and enhance the product quality.

[0025] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes, and decorations made by any person skilled in the relevant art to the above embodiments based on the technical solution of the present invention all fall within the protection scope of the present invention.
