Description

[0002] For the preparation and processing of the substrate, there is a planar or semi-enclosed film pasting process. During this period, the substrate is adsorbed and positioned by a vacuum adsorption jig. Therefore, the accurate positioning of the substrate is related to the final precision and quality of the film pasting.

[0003] In order to avoid displacement of the substrate during film pasting, a larger negative pressure suction force is often provided. In this way, the substrate near the adsorption port is subjected to excessive stress, resulting in abnormal deformation and affecting the film pasting effect.

[0004] At the same time, the sealing requirement of the adsorption process for the substrate bonding position is high. At present, the conventional sealing auxiliary method is to send the prepared jig to a rubber factory to distribute rubber structures for sealing at the corresponding positions of the jig by pouring rubber.

The following is a detailed description of the preferred embodiments of the substrate deformation-resistant film pasting jig in combination with the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0024] The meanings of the reference signs in the drawings are as follows.

[0030] The specific embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0031] As Figure 1 The substrate anti-deformation type film pasting jig, including mounting base 1, it is different from the fact that: mounting base 1 is provided with placing base 2, placing base 2 is distributed with several adsorption channels 8, and placing base 2 is distributed with positioning space 3, for carrying substrate, after starting vacuum device, it is adsorbed. At the same time, placing base 2 is installed with sealing mechanism 4 at the edge of positioning space 3, avoid the gap of substrate and the edge of positioning space 3, influence vacuum adsorption effect. And, placing base 2 is installed with positioning assembly 5 above sealing mechanism 4, can position sealing mechanism 4, avoid its loosening. During implementation, several supporting devices 6 are distributed in positioning space 3. In this way, the proper lifting of the substrate below can be realized, avoiding the abnormal deformation of the lower part of the substrate, especially the part close to the adsorption channel 8, under excessive negative pressure adsorption, ensuring that the film can be effectively attached to the substrate except the lower part during film pasting, avoiding defects such as film lifting or wrinkling due to deformation.

[0032] In combination with a preferred embodiment of the utility model, placing base 2 is provided with a receiving groove at the edge of positioning space 3, sealing mechanism 4 is embedded in the receiving groove, and the upper surface of sealing mechanism 4 is in contact with positioning assembly 5. In this way, sealing mechanism 4 can be effectively limited, and there is no loosening in contact with the base. At the same time, it also will not loosen from the edge of positioning space 3 when subjected to negative pressure adsorption.

[0033] Further, positioning assembly 5 is a guide pressing plate, the guide pressing plate is screw-connected with placing base 2, and a placing reserved opening is formed in the guide pressing plate. In this way, the guide pressing plate can be effectively buckled above sealing mechanism 4 by using the similar mouth-shaped structure, and is connected with placing base 2, so as to achieve moderate clamping and limiting of sealing mechanism 4. At the same time, the edge of the placing reserved opening is distributed with a circular arc chamfer.

[0034] In combination with actual implementation, the sealing mechanism 4 is a square rubber sealing strip, which can be distributed according to the shape of the positioning space 3. Meanwhile, in order to meet the needs of some special sealing contact, the upper surface of the square rubber sealing strip extends a convex contact structure. In this way, after the substrate is placed, the square rubber sealing strip can completely fit the adsorption range below the substrate, and air leakage will not occur. If the shape of the substrate changes, only the same matching square rubber sealing strip needs to be replaced, which greatly reduces the use cost and improves the compatibility of the entire device. If the shape changes too much, the corresponding placing base 2 can be reconfigured.

[0035] Further, the support device 6 is a support column or a support block. In order to meet the flexible contact and not scratch the surface of the substrate in the local position of the support substrate, the support device 6 is made of a high polymer material, and the material has a suitable softness.

[0036] Meanwhile, in order to achieve a more fitted bottom storage and avoid the side edge from being raised to affect the air tightness during adsorption, the utility model is distributed with a give-way slot 7 in the positioning space 3.

[0037] Further, a hanging hole 9 can be provided at the side end of the mounting base 1. In this way, when the adsorption pipeline is laid out, various pipeline positioning supports can be installed through the hanging hole 9. The installation of the adsorption pipeline is a known technology in the art, and will not be repeated here.

[0038] The working principle of the utility model is as follows:

[0039] The substrate is placed in the positioning space 3, and the lower end protruding part is stored in the give-way slot 7. Then, the placing frame amount of the substrate is slightly adjusted, so that the edge is fitted by the sealing mechanism 4.

[0040] Next, the vacuum device is started to meet the adsorption positioning of the substrate of the utility model. Then, the corresponding film bonding processing can be carried out.

[0041] Through the above description and in combination with the drawings, it can be seen that after the utility model is adopted, the following advantages are obtained:

[0042] 1. The square rubber sealing strip is used, which is convenient to install and does not need complicated rubber casting process, thereby reducing the manufacturing and maintenance cost.

[0043] 2. By replacing the square rubber sealing strip, various conventional substrate shapes can be adapted for adsorption assistance, and the versatility is good.

[0044] 3. The positioning assembly is used to participate in the positioning of the sealing mechanism, which can realize appropriate clamping or pressing combination, and improve the air tightness during use.

[0045] 4. The whole structure is simple, easy to manufacture and use, and can be adapted to the current conventional adsorption pipe layout.

[0046] In addition, the indicated direction or position relationship described in the utility model is based on the direction or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and is not indicative or suggestive of the device or structure indicated must have a specific direction, or be operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0047] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and it should be pointed out that, for ordinary skilled persons in the technical field, without departing from the technical principles of the utility model, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the utility model.
