Machine vision-based touchpad alignment system

Abstract

The invention discloses a machine vision-based lamination and alignment system for a touch panel, which includes a frame, a platform provided with a position to be grasped, a lamination position and a calibration position, a conveying and positioning device, an input mechanism, and an output for outputting a pasted product. mechanism, a manipulator for grabbing aluminum sheets, and a calibration alignment mechanism for calibrating the manipulator, the platform is horizontally supported on the frame, and the conveying and positioning device, input mechanism and output mechanism are all extended from the inside of the frame The delivery outlet of the delivery positioning device is directly opposite to the position to be grasped, and the delivery outlet of the input mechanism and the delivery inlet of the output mechanism are respectively opposite to the fitting position; the calibration alignment mechanism is located directly below the calibration position; The taking position, fitting position and calibration position are all spaced apart from each other, and are all located within the coverage area projected on the platform by the movement track of the manipulator; the calibration alignment mechanism is electrically connected with the manipulator. The invention can automatically and accurately align and mount aluminum sheets on the touch panel.

Description

technical field [0001] The invention relates to a fitting alignment device, in particular to a machine vision-based touch panel fitting alignment system. Background technique [0002] At present, in the placement process of circuit boards, it is often necessary to position the aluminum sheet first to accurately attach the aluminum sheet to the circuit board. For example, in the placement process of a touch panel, it is necessary to place two small rectangular aluminum sheets and A strip of aluminum is attached to the back of the touchpad for capacitive sensing. [0003] Touch manufacturers have encountered the same problem, that is, the yield rate of multi-touch panels is not easy to improve, especially for large-sized touch panels, it is very difficult to improve the yield rate in terms of glass coating and lamination. This is because the touch panel is limited to the alignment accuracy of the bonding process in the production process, resulting in defective products, and ...

AI Technical Summary

Problems solved by technology

Specifically, if the alignment of each aluminum sheet is inaccurate, it will affect the assembly and affect the capacitance conductivity, which will increase the defective rate of the touch panel.
