Adhesive tape coating and positioning pasting tool and adhesive tape coating and positioning pasting method

Abstract

The invention discloses an adhesive tape coating and a positioning pasting tool. A cavity consistent with a pasting positioning plate in shape is formed in the top end face of a tool base, and a limiting step is formed on the edge of the top of the cavity in the circumferential direction. A narrow adhesive tape through groove is formed in the pasting positioning plate, the two sides of the front face of the narrow adhesive tape through groove expand outwards to form a wide adhesive tape groove, the narrow adhesive tape through groove and the wide adhesive tape groove share a same center line and are equal in length, and operation holes are formed in the two ends of the narrow adhesive tape through groove. Repeat use can be achieved, operation is convenient, rapid and reliable, the principle is simple, cost waste is reduced, and popularization and use are convenient. The invention further discloses a method. The method comprises the steps that the front face of the pasting positioning plate is positioned on the tool base in a covering way; a wide adhesive tape is attached to the interior of the wide adhesive tape groove in the length direction; the pasting positioning plate is taken down and turned to the back face, and the narrow adhesive tape is pasted on the narrow adhesive tape through groove in a covering way; and the combined pasting adhesive tape is taken down through the operation hole and is wrapped on the side wall of the optical assembly to complete the manufacturing of the assembly.

Description

technical field [0001] The invention relates to the technical field of manufacturing special optical components, in particular to a tape coating and positioning and pasting tooling and a tape coating and positioning and pasting method. Background technique [0002] With the development of the times, display technology has also made significant progress, changing with each passing day, LCD products as display media are also tending to diversify, and the requirements for reliability, practicality, and functionality of display products are also constantly changing with market demand. promote. For special display modules and display components, the requirements for the functional properties of the process auxiliary materials required in each process are constantly increasing. [0003] At present, for the tapes used in the various processes of the special display, there are situations in which it is not easy to operate in some processes, the existing materials cannot be tested w...

Problems solved by technology

[0005] However, inner wrapping and U-wrapping (see Figure 3) has the following disadvantages in the production: long time for lamination, it is easy to produce dirty spots, and the back glue of the optical tape will overflow when it is rubbed against the sheet when it is shaken. , The positioning of the inner tape and the tape of the U-shaped package is not accurate enough, and the function of limiting and covering is lacking when wrapping (causing scratches on the optical sheet), and the cost of custom tape is high, etc.
