Description

Technical Field

[0001] This utility model relates to the field of membrane bonding technology, and more specifically, to a high-precision airbag bonding device. Background Technology

[0002] In the field of material bonding, for bonding flexible films to substrates, some existing technologies (such as patent documents with publication numbers "CN107020785A" and "CN110126249A") use airbags to lift the flexible film, so that the center of the flexible film contacts the substrate first, and then gradually bonds to both sides, thereby reducing air bubbles. However, in these existing technologies, the flexible film is often fixed by a carrier mold or adhesive tape. This fixing method is unreliable, and the flexible film is prone to slipping during bonding, resulting in low bonding accuracy. Moreover, the carrier mold or adhesive tape needs to be replaced frequently, leading to low bonding efficiency. Utility Model Content

Detailed Implementation

[0024] Example 1

[0025] refer to Figure 1 and Figure 2A high-precision airbag bonding device includes a rigid plate adsorption platform 200 and a membrane adsorption platform 100 that can move relative to each other. The membrane adsorption platform 100 is used to adsorb and fix a flexible film 600, and the rigid plate adsorption platform 200 is used to adsorb (the adsorption method can be conventional vacuum adsorption) and fix a substrate 700 that is bonded to the flexible film 600.

[0026] refer to Figure 3 and Figure 4 The membrane adsorption platform 100 includes a platform base 101, a flexible deformation layer 102, and a flexible pad 103.

[0027] The flexible deformable layer 102 is fixed to the top of the platform base 101. Further, in this embodiment, the top of the platform base 101 is provided with a positioning groove 1012 that mates with the flexible deformable layer 102, facilitating the positioning of the flexible deformable layer 102. The top of the platform base 101 has an upper concave surface 1011, and the bottom of the flexible deformable layer 102 has a lower concave surface 1021. After the platform base 101 and the flexible deformable layer 102 are assembled and connected, the upper concave surface 1011 and the lower concave surface 1021 form an airbag. When the airbag is inflated, it can lift the middle of the flexible deformable layer 102 upwards, deforming it into an arched structure. This allows the flexible film 600 to first contact the substrate 700 when it is applied, and then gradually adhere to both sides, helping to reduce air bubbles. Based on this, it should be understood that the platform base 101 should be provided with an inflation / deflation port for inflation and deflation. In this embodiment, the inflation / deflation port is located at the bottom of the platform base 101.

[0028] The flexible pad 103 is fixed to the top of the flexible deformable layer 102. The top of the flexible deformable layer 102 is provided with a vacuum adsorption groove 1022. The flexible pad 103 is provided with a vacuum hole communicating with the vacuum adsorption groove 1022. It should be understood that in practical applications, the side of the flexible deformable layer 102 should be provided with a suction hole communicating with the vacuum adsorption groove 1022. The suction hole is connected to an external negative pressure device to achieve vacuuming, thereby fixing the flexible film 600 through vacuum adsorption. Therefore, this invention, based on the airbag bonding method, fixes the flexible film 600 through vacuum adsorption, making the fixing method more reliable, preventing the flexible film 600 from sliding during bonding, improving bonding accuracy, and avoiding the need to replace the carrier mold or adhesive tape, thus improving bonding efficiency.

[0029] It should be understood that the flexible pad 103 and the flexible deformable layer 102 have good elasticity, so that they can deform to form an arched structure when the airbag is inflated, and return to their original shape when deflated. As an option, the flexible pad 103 and the flexible deformable layer 102 in this embodiment are both made of silicone. In other embodiments, other materials can of course be selected, such as any one of silicone rubber, EPDM rubber, natural rubber, butadiene rubber, butyl rubber, styrene-butadiene rubber, and nitrile rubber.

[0030] Based on the above, in this embodiment, a porous support pad 104 made of porous material is fixed on the top of the flexible pad 103, that is, the porous support pad 104 contacts the flexible film 600. It is worth noting that the porous support pad 104 is made of porous material, that is, the material itself has nanoscale (or microscale) pores, a smooth surface and breathability, avoiding direct contact between the vacuum pores of the flexible pad 103 and the flexible film 600, that is, avoiding the flexible film 600 from being squeezed and deformed at the vacuum pores during bonding. As an option, the porous support pad 104 in this embodiment is porous paper. In other embodiments, other materials can of course be selected, such as porous silicon, porous ceramics, carbon nanotube sponge, etc.

[0031] It is worth noting that in practical applications, the rigid plate adsorption platform 200 can be positioned above and the film adsorption platform 100 below (of course, their positions can also be interchanged). The rigid plate adsorption platform 200 is fixed, while the film adsorption platform 100 is raised and lowered via a lifting platform (not shown). Furthermore, the bonding device provided in this embodiment also includes a CCD alignment device (not shown), positioned between the rigid plate adsorption platform 200 and the film adsorption platform 100. The CCD alignment device takes a picture using a CCD camera to detect whether the flexible film 600 is aligned with the substrate 700. After detection, the CCD alignment device exits the picture-taking position to avoid affecting subsequent bonding operations. Based on this, it is easy to understand that an alignment compensation mechanism (not shown, which can be a moving platform capable of moving in two directions) can also be set to adjust the overall position of the film adsorption platform 100, facilitating better alignment of the flexible film 600 with the substrate 700.

[0032] Example 2

[0033] refer to Figure 5 and Figure 6 This embodiment is a further optimization based on Embodiment 1. In this embodiment, the rigid plate adsorption platform 200 is disposed inside the first cavity 300, and the membrane material adsorption platform 100 is disposed inside the second cavity 400 (in practical applications, the edge of the platform base 101 of the membrane material adsorption platform 100 can also be used as the second cavity 400). After the first cavity 300 and the second cavity 400 are pressed together, they enclose and form a sealed exhaust cavity 500. In practical applications, the exhaust cavity 500 can be drawn by a negative pressure device to assist in exhaust (exhaust direction is as follows). Figure 6 (As indicated by the middle arrow), to better reduce bubbles.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
