Problems solved by technology

However, in the actual operation process, we found that the film to be attached automatically peeled off by the feeding mechanism will be offset within a certain range, so that the film to be attached by the mechanical arm will have an adsorption offset problem (due to the incorrect position of the adsorption , the film to be attached will sag and bend on one or both sides under the action of gravity), which directly affects the photographing results, which in turn leads to inaccurate position information collected, and ultimately affects the alignment effect of the two

Abstract

The invention provides a backlight CCD laminating technology and a backlight CCD laminator. The membrane alignment working procedure of the backlight CCD laminating technology comprises the following steps that a CCD alignment camera photographs a to-be-assembled workpiece initially located on a working table once to complete position information image collection of the to-be-assembled workpiece; position information collected by the CCD alignment camera and the preset standard position of the to-be-assembled workpiece are compared and calculated to obtain the position offset of the to-be-assembled workpiece; according to the position offset of the to-be-assembled workpiece, a locating fine adjustment platform adjusts the position of a to-be-laminated membrane arranged corresponding to the to-be-assembled workpiece, so that alignment of the position of the to-be-assembled workpiece to the position of the to-be-laminated membrane is completed. According to the backlight CCD laminating technology and the backlight CCD laminator, alignment operation before laminating in the assembling process of the rear section of a backlight product can be completed accurately.

Description

technical field [0001] The invention relates to the technical field of backlight automatic film laminating machine equipment, in particular to a backlight CCD film laminating process and a backlight CCD film laminating machine. Background technique [0002] As we all know, the backlight CCD film laminating machine is mainly used for the back-end assembly of backlight products. When performing automatic lamination, it is necessary to collect the position information of the workpiece to be assembled on the working platform and the film to be pasted from the feeding mechanism, so that the positions of the two are aligned, and finally the lamination operation of the two is realized. [0003] When the existing backlight CCD film laminating machine performs alignment, it usually uses a three-dimensional movable mechanical arm to suck up the film to be pasted from the feeding mechanism, and then moves to the top of the CCD alignment camera for position information collection, and t...
