Description

Technical Field

[0001] This utility model relates to the field of adsorption bonding fixtures, and in particular to a curved surface structure pressure-sensitive adhesive adsorption bonding fixture. Background Technology

[0002] An adsorption bonding fixture is a tool or device specifically designed to precisely adsorb and bond materials (such as films, tapes, etc.) onto a target surface. It is typically used in scenarios requiring high-precision bonding.

[0003] The curved surface pressure-sensitive adhesive adsorption and bonding fixture is a tool or device specifically designed to precisely adsorb and bond pressure-sensitive adhesive onto curved surfaces.

[0004] Existing curved surface pressure-sensitive adhesive adsorption bonding fixtures have the following shortcomings:

[0005] In the manufacturing of curved products, the bonding process faces numerous challenges. On the one hand, the unique structural characteristics of curved products make it impossible to directly use rollers or flat bonding fixtures for bonding operations. On the other hand, when using existing bonding methods to bond curved products with pressure-sensitive adhesive, insufficient pressing is common, resulting in insufficient bonding strength at the bonded parts, affecting the overall quality and service life of the product. Pressing air bubbles are also a prominent issue. These air bubbles not only affect the product's appearance but may also cause localized stress concentration during subsequent use, reducing the product's reliability. In addition, bonding misalignment is equally important, as it can lead to deviations in the relative positions between product components, and in severe cases, even prevent the product from being assembled and used properly. Utility Model Content

[0006] This invention can be compatible with heat-sensitive adhesive bonding of curved surface products of various sizes, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a curved structure pressure-sensitive adhesive adsorption bonding fixture, comprising a curved vacuum head and a base, wherein the outer wall of the curved vacuum head is provided with fixing holes, a set of temperature control feedback lines is provided on the outer wall of the curved vacuum head, and a set of positioning posts are fixedly installed on the outer wall of the curved vacuum head. Through the above components, the bonding of curved structure products can be realized, which can effectively improve problems such as insufficient pressing, air bubbles or misalignment that occur during the bonding process.

[0008] Preferably, the outer wall of the base is provided with base fixing holes, and the top of the base is provided with a product placement slot. Through the base fixing holes, the base can be stably fixed on the workbench or related equipment. The product placement slot is specially designed for placing curved products to be pressed. Its shape and size match the curved products, which can accurately position the products and ensure that the products are in the correct position during the bonding process.

[0009] Preferably, the inner wall of the product placement slot is provided with positioning post holes, and the outer wall of the base is provided with heat-sensitive adhesive guide holes. The positioning post holes are used in conjunction with the positioning posts on the curved vacuum press head to achieve precise positioning. The heat-sensitive adhesive guide holes can be used to guide the position and direction of the heat-sensitive adhesive during the bonding process.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the present invention can be compatible with the heat-sensitive adhesive pressing of curved surface products of various sizes. Only the position of the curved surface press head needs to be adjusted according to the actual product structure. This effect greatly expands the application range of the fixture, and at the same time can improve production efficiency, reduce process defects, and reduce production waste.

[0012] 2. In this utility model, the precise positioning of the heat-sensitive adhesive by the guide column effectively avoids misalignment during the bonding process. Through vacuum adsorption and reasonable heating and pressurization design, the heat-sensitive adhesive is bonded more fully, reducing defects such as insufficient pressing and air bubbles, and improving the product yield.
