Touchpad fitting alignment system based on machine vision

Abstract

The invention discloses a touchpad fitting alignment system based on machine vision. The touchpad fitting alignment system comprises a rack, a platform with a position to be grabbed, a fitting position and a calibration position, a conveying and locating device, an input mechanism, an output mechanism, a mechanical arm and a calibration and alignment mechanism, the output mechanism is used for outputting a finished fit product, the mechanical arm is used for grabbing aluminum sheets, the calibration and alignment mechanism is used for calibrating the mechanical arm, the platform is horizontally borne by the rack, the conveying and locating device, the input mechanism and the output mechanism all stretch out from the rack, a conveying outlet of the conveying and locating device exactly faces to the position to be grabbed, and a conveying outlet of the input mechanism and a conveying inlet of the output mechanism exactly and respectively face the fitting position. The calibration and alignment mechanism is arranged under the calibration position. The position to be grabbed, the fitting position and the calibration position are separated from one another, and are all located within the coverage range of the projection of the movement trail of the mechanical arm on the platform. The calibration and alignment mechanism is electrically connected with the mechanical arm. According to the system, the aluminum sheets can be pasted on a touchpad automatically and precisely in an alignment mode.

Description

[0001] technical field [0002] The invention relates to a fitting alignment device, in particular to a machine vision-based touch panel fitting alignment system. Background technique [0003] 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. [0004] 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 produ...

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.
