Precision detection machine for large-size panel after partial pasting

Abstract

The invention discloses a precision detection machine for a large-size panel after partial pasting, which comprises a transmission mechanism, a detection mechanism and a moving and discharging mechanism, and is characterized in that the transmission mechanism is horizontally arranged on a machine table and extends to the outer side of the machine table so as to receive materials of a previous work station; the detection mechanism is erected above the transmission mechanism and linearly walks in the longitudinal direction and the transverse direction in the horizontal plane to adjust the position. The carrying and discharging mechanism is arranged above the conveying mechanism and located on the rear side of the detection mechanism, the conveying mechanism drives the borne materials to linearly move to the position below the detection mechanism, the detection mechanism detects the surfaces of the materials, and the detected materials are moved to the position below the carrying and discharging mechanism through the conveying mechanism and are carried and discharged through the carrying and discharging mechanism. According to the invention, automatic material receiving and transferring, automatic detection and moving and blanking are realized, the detection efficiency of the large-size panel is effectively improved, the upper and lower detection planes are integrated, multi-point detection of the upper and lower side surfaces of the panel and in the horizontal plane is realized, and the detection precision is effectively improved.

AI Technical Summary

Problems solved by technology

The following technical problems need to be solved in the detection process after the large-size panel is offset: 1. In the integrated design process of the large-size panel production automation production line, it is necessary to solve the problem of automatic connection and transfer of the panel after offset, as well as automatic detection and removal The problem of blanking; 2. After the polarizer is attached, it is necessary to ensure the accuracy of the polarizer. The complete alignment of the polarizer and the panel is the quality control direction of the bonding, so the position accuracy problem after the partial attachment needs to be solved; 3. Especially for large-size panels, due to their large size, there is a small positional deviation after the polarizer is attached. From an overall point of view, if there is a biased attachment error, the polarizer will not cover the panel at the side or corner of the panel. Therefore, the accuracy detection requirements for large-size panels after offset mounting are higher, and single / one-way CCD detection cannot meet the detection requirements
