Embodiment Construction
[0044] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the specific details described below are only some embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described here. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other e...

The invention provides a polaroid laminating precision detection device and a control method thereof, and relates to the technical field of display equipment production. The polaroid laminating precision detection device comprises a turnover supporting mechanism, a precision detection camera, a deviation correction detection mechanism and a plane displacement mechanism; wherein the turnover supporting mechanism comprises a steering motor and a fixed supporting device used for fixing and supporting the polaroid, and the fixed supporting device comprises a connecting part connected with the steering motor, and a first adsorption supporting device and a second adsorption supporting device which are rotationally connected with the connecting part; in the first state, the second adsorption supporting device fixedly supports the polaroid, and the first adsorption supporting device is in a folded state; and in the second state, the first adsorption supporting device fixedly supports the polaroid, and the second adsorption supporting device is in a folded state. In combination with the control method, the embodiment of the invention can solve the problem that the detection precision is affected due to the fact that the polaroid is easy to deviate when being transferred in the photographing detection process.
Description
technical field [0001] The invention relates to the technical field of display equipment production, in particular to a polarizer bonding accuracy detection device and a control method thereof. Background technique [0002] In the production process of liquid crystal display equipment, it is generally necessary to test the lamination accuracy of polarizers. The current alignment method generally uses mechanical alignment and CCD visual alignment accuracy detection to correct. Among them, the CCD visual alignment accuracy detection is completed by the CCD visual alignment accuracy detection camera, which is a commonly used detection equipment in the field of panel lamination accuracy detection. The characteristic position on the product is photographed, and the image data is collected by the image processor for image processing, and then the actual offset value of the product is calculated by comparing with the previously set reference position, so as to achieve fast, closed-...
