Embodiment Construction

[0040] A high-precision small chip collage system for preparing a monolithic integrated capacitive touch screen, the system includes:

[0041] Bearing mother board: the structure of the bearing mother board is as follows figure 1 As shown, the carrying mother board 1 is a large piece of glass with a relatively large area, and is used to carry small pieces of glass 2. The carrying mother board is provided with an alignment mark for precise positioning, and the alignment mark includes an alignment origin hole 3 (circle holes or square holes), ITO alignment MARK4 and silk screen alignment MARK5.

[0042] Visual recognition system: mainly CCD camera system and image processing software system, used to identify the position information of the carrier motherboard and the coordinate positions of the small pieces of glass arranged on the carrier motherboard.

[0043] Mask system: used to design the filling pattern of the lithography mask and generate the coordinate position of the fi...

Abstract

The invention discloses a high-precision small-piece collaging system for preparing a monolithic integrated capacitive touch screen. The high-precision small-piece collaging system for preparing the monolithic integrated capacitive touch screen comprises a bearing motherboard, a visual identification system, a mask system, a typesetting system, a detecting system, a sorting system and a leveling and baking system. The high-precision small-piece collaging system can ensure that a small-piece glass fit position accurately overlaps with a mask shape. In the process of manufacturing small-piece glass, reinforcement stress is not restricted any longer, the developing and the manufacturing of novel products can be conducted, less environment pollution exists, the requirement of industrialized mass production can be met, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a touch screen manufacturing system, in particular to a high-precision small-chip collage system in the manufacturing process of a single-chip integrated capacitive touch screen. Background technique [0002] The existing OGS technology for parallel light production is mainly divided into the following three categories: [0003] Large-scale production process, using the strengthened glass substrate, using a parallel light exposure machine, under the action of a certain typesetting mask, forms a certain typesetting large piece of OGS, and then performs silk screen printing, cutting, CNC and secondary strengthening processes to obtain small pieces OGS products. [0004] In the small-chip process, a small piece of CoverLens is formed first, and then the small-chip process parallel light exposure machine is used to use the mask (MASK). The ITO process first captures the black or white frame for alignment, and each subsequent proce...
