Vision alignment platform

Abstract

The invention discloses a vision alignment platform. The platform comprises a controller, an alignment mechanism and a photographing unit, wherein a display screen is arranged on the controller, analysis and calculation software is embedded in the controller, the controller is in signal communication with the alignment mechanism through a signal line, the alignment mechanism comprises a base, four XYtheta sliding platforms, three adjusting screw rods and a working platform, the four XYtheta sliding platforms are evenly distributed in the center of the base, the three adjusting screw rods are arranged on outer sides of the four XYtheta sliding platforms and act under the driving of three external motors respectively to drive the XYtheta sliding platforms to act, and the photographing unit is fixed above the working platform through a fixing support; positions of products are acquired by the photographing unit, position deviations are calculated accurately by the analysis and calculation software in the controller, the products are moved to accurate positions by the alignment mechanism, so that quick and accurate alignment is realized, the alignment accuracy is high, the error is very small, the yield of the products produced through aligned lamination is high, the lamination efficiency is improved, and the lamination quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of automatic alignment devices, in particular to a visual alignment platform with accurate alignment. Background technique [0002] Mobile phone screens, computer screens, etc. need to be filmed on the screen before leaving the factory. The most primitive film is manually pasted on the screen. This method is inefficient, and the precision of the paste is low, and the rate of defective products is high. , is not suitable for large-scale production in factories. In order to solve this problem, some people propose to use fixtures to assist film attachment, fix the screen on the fixture, and then manually paste the film. This method has a certain improvement in efficiency, but The accuracy of lamination is not enough, the rate of good products is not high, and frequent rework is required, which also reduces the efficiency of film attachment to a certain extent, and does not effectively solve the fundamental problem. In or...
