Supplying and correcting system and method for COG (Chip on Glass) preformer

Abstract

The invention discloses a supplying and correcting system and a supplying and correcting method for a COG (Chip on Glass) preformer. The system comprises a supplying tray, an X axle motor, a Y axle motor, an imaging system, a control system and a correcting mechanism, wherein the supplying tray is used for supplying chips; the X axle motor and the Y axle motor are respectively used for driving the movement of the supplying tray in an X axle direction and a Y axle direction; the imaging system is used for acquiring the images of the chips; the control system is connected with the imaging system and used for building chip coordinates, calculating the biases between the chip coordinates and standard coordinates and controlling the feeding quantity of the X axle motor or / and the Y axle motor; the correcting mechanism is arranged on the supplying tray and used for correcting the postures of the chips. According to the supplying and correcting system for the COG (Chip on Glass) preformer, the supplying mechanism and the correcting mechanism are arranged on the same platform, IC (Integrated Circuit) supply continuous production can be realized, and the production efficiency is improved; the structure is simple, the product qualified rate is improved, and the production cost is reduced. The supplying and correcting action of the method is finished in the same platform, the production efficiency is improved, and the product qualified rate is ensured.

Description

technical field [0001] The invention relates to COG pre-pressing equipment, in particular to an IC supply and correction mechanism for COG pre-pressing. [0002] The invention also relates to a method of COG preloaded IC supply and rectification. Background technique [0003] COG (Chip-on-glass) process is a flip chip (flip chip) technology, that is, the chip (ie IC) is directly aligned with the circuit on the glass substrate or bonded to the edge of the matrix liquid crystal display, and conducts electricity through other intermediate materials. medium to achieve the purpose of reducing the volume and weight of the LCD module. [0004] Now, in the COG process, in the pre-pressing section, the supply mechanism of the COG process equipment first supplies the tray to supply the IC, and then the correction mechanism of the COG process equipment corrects the relative posture of the IC to eliminate X, Y, θ and other error deviations , in order to meet the requirements of precis...

AI Technical Summary

Problems solved by technology

[0005] However, the structure of the above-mentioned COG process equipment is relatively complicated

In the production process, IC supply and rectification are not completed on the same platform, and two independent agencies are required to complete it. Not only is it time-consuming and laborious, the production efficiency is low, and large errors will occur, the accuracy cannot be guaranteed, and the product yield rate is low.
