Abstract
Description
Technical Field
[0001] The utility model relates to the field of display screens, in particular to an anti-static substrate structure. Background Art
[0002] When making modules such as touch screens and displays, they need to go through processes such as yellow light, silk screen printing, binding, and lamination. During the above-mentioned production processes, the substrate will be fixed to the table through vacuum adsorption, and then glue coating, exposure, silk screen printing, binding, and lamination will be completed. After breaking the vacuum, the substrate on the table is taken out by a robot. Since the table is made of metal or plastic, continuing to operate after the vacuum is broken will generate static electricity on the table, which will cause damage to the product circuit and lead to poor product functionality.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] This application proposes an anti-static substrate 10 structure, please refer to Figure 1, including: a substrate 10, a table 20 and a polymer film layer 30. The polymer film layer 30 is non-conductive, so as to prevent static electricity generated on the table 20 from being transferred to the substrate 10 through the polymer film layer 30, thereby damaging the substrate 10 and causing a defective product. The polymer film layer 30 is arranged between the table 20 and the substrate 10 to isolate the table 20 and the substrate 10. A plurality of adsorption holes 31 are provided on the polymer film layer 30. The table 20 adsorbs the substrate 10 through the adsorption holes 31, so that the polymer film layer 30 and the substrate 10 are fully attached to the table 20. A layer of polymer film layer 30 is covered on the table 20 to prevent static electricity from being generated on the substrate 10, to avoid static electricity from damaging the product, and to ensure the functionality of the product. Preferably, the table 20 is a metal plate or a plastic plate.
[0025] It should be noted that the table 20 is the table top on which the screen printer places the substrate 10. During screen printing, the substrate 10 is placed flat on the table top, and then the scraper of the screen printer moves to transfer materials such as blue film to the substrate 10 through the mesh of the mesh. The substrate 10 is a plate material used to make circuit patterns, which is a glass plate or a multilayer plate.
[0026] In one embodiment, the pore size of the adsorption holes 31 of the polymer film layer 30 is 0.02mm-0.05mm, which is small enough so that the table 20 does not contact the substrate 10, further ensuring insulation between the two. In order to prevent the substrate 10 from contacting the table 20, the length of the polymer film layer 30 is greater than the length of the substrate 10, and the width of the polymer film layer 30 is greater than the width of the substrate 10, to prevent static electricity on the table 20 from being directly introduced into the substrate 10 and damaging the substrate 10. Furthermore, the spacing between the adsorption holes 31 of the polymer film layer 30 is 0.06mm-0.13mm. When the area of the polymer film layer 30 is constant, it is ensured that a sufficient number of adsorption holes 31 are set to ensure that the table 20 adsorbs the substrate 10 on the polymer film layer 30 through the adsorption holes 31, so that the substrate 10 is attached to the polymer film layer 30, ensuring the accuracy of subsequent operations. For further information, please refer to Figure 2 and Figure 3 , the adsorption hole 31 is a square adsorption hole 31 or a circular adsorption hole 31.
[0027] In one embodiment, the insulation impedance of the polymer film layer 30 is 10^6Ω-10^8Ω, and sufficient impedance is set to prevent the static electricity generated on the platen 20 from being transmitted to the substrate 10 through the polymer film layer 30, further ensuring the functional integrity of the substrate 10. Furthermore, the polymer film layer 30 is a PTFE layer. In addition, the thickness of the polymer film layer 30 ranges from 0.4mm to 0.6mm, and the thickness is designed to be small enough not to affect the original coordination with external equipment, thereby ensuring the accuracy of the operation.
[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
