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

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.
