Description

Technical Field

[0001] The utility model relates to the technical field of grinding belts, in particular to a 180mm grinding belt. Background Art

[0002] When the battery module is assembled, some parts (such as the shell or shielding cover, etc.) have burrs when they are produced, and the burrs need to be removed. The main way to remove the burrs is through polishing. During the grinding process of the battery module parts, grinding tools are needed, generally grinding wheels or sandpaper. Grinding wheels and sandpaper are inelastic when contacting parts, which can easily cause edge collapse and over-grinding. In addition, traditional grinding media can easily scratch the surface of the component layer, and there are coarse lines, etc., which affects the grinding quality of the parts and easily scratches the battery during assembly.

[0003] In view of this, the applicant conducted an in-depth study on the mold structure of the components assembled in the battery module, which resulted in the present case. Utility Model Content

[0004] The utility model aims to provide a 180mm grinding belt with stable polishing quality and relatively high grinding effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a 180mm grinding belt, including a combined sanding belt with a circumference of 180mm and a width of 3.2mm. The combined sanding belt is bonded with a base layer, a middle layer and an inner layer from the outside to the inside. The base layer is a 3000-4000 mesh sanding belt, the middle layer is a foam buffer layer, and the inner layer is a tension cloth.

[0006] Furthermore, the foam cushioning layer is made of foam with medium hardness.

[0007] By adopting the above technical scheme, the utility model has the following beneficial effects: the utility model has a simple structure and strong pertinence. By setting the outer layer to an optional imported sanding belt with 3000-4000 mesh, the polishing quality and the brightness of the product surface can be effectively guaranteed. The middle layer and the inner layer are made of medium-hard foam and tension cloth, which can ensure the elasticity of the polishing belt, and also ensure the tension and tension of the polishing belt, effectively ensuring the stability of the polishing quality and the polishing effect.

[0010] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0011] With the development of new energy, battery modules have become a commonly used product. When the battery module is assembled, some parts (such as shells, shielding covers, etc.) have burrs when they are produced, and the burrs need to be removed. The main way to remove the burrs is through polishing. During the grinding process of battery module parts, grinding tools are needed, generally grinding wheels or sandpaper. Grinding wheels and sandpaper are inelastic when contacting parts, which can easily cause edge collapse and over-grinding. In addition, traditional grinding media are prone to scratches on the surface of the component layer, and there are coarse lines, etc., which affect the grinding quality of the parts and easily scratch the battery during assembly. In order to solve the above problems, the present application provides a special 180mm grinding belt to ensure the brightness of the surface of the battery module parts.

[0012] See also Figure 1 and Figure 2 This embodiment provides a 180mm grinding belt, which is used in an automatic grinding device. The 180mm grinding belt includes a combined sanding belt 100 with a circumference of 180mm and a width of 3.2mm, and the combined sanding belt 100 is sequentially bonded with a base layer 10, an intermediate layer 20 and an inner layer 30 from the outside to the inside;

[0013] In order to ensure the elasticity, pulling force and tension of the 180mm grinding belt and improve the grinding effect, the base layer 10 is a 3000-4000 mesh sanding belt, and the sanding belt is imported. The sanding belt can be 3000 mesh or 4000 mesh. By setting the outer layer to a 3000-4000 mesh optional imported sanding belt, the polishing quality can be effectively guaranteed and the brightness of the product surface can be guaranteed.

[0014] The middle layer 20 is a foam buffer layer made of medium-hard foam. The middle layer 20 is made of medium-hard foam, which can ensure the softness and elasticity of the grinding belt and play a buffering role, thereby effectively ensuring the grinding effect during grinding.

[0015] The inner layer 30 is a tension cloth. The use of tension cloth can enhance the tension and tension of the grinding belt. The tension cloth is a non-woven fabric composed of PP+PE film, which has elasticity and resilience. This fabric is widely called stretch cloth because its elasticity is enhanced by adding elastic masterbatch. It can be stretched not only horizontally but also vertically. This feature makes the tension cloth perform well in a variety of application scenarios. In addition, the tension cloth is also called "ribbed tissue", stretch non-woven fabric or elastic non-woven fabric. The stretch non-woven fabric has been specially treated and has good wear resistance and flame retardant properties. It is not easy to burn and will not melt, ensuring the safety of users.

[0016] To sum up, the utility model has a simple structure and strong pertinence. By setting the outer layer to an optional imported sanding belt with a mesh size of 3000-4000, the polishing quality and the brightness of the product surface can be effectively guaranteed. The middle layer 20 and the inner layer 30 are made of medium-hard foam and tension cloth, which can ensure the elasticity of the polishing belt, as well as the tension and tension of the polishing belt, and effectively ensure the stability of the polishing quality and the polishing effect.

[0017] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
