According to the screen laminating method, compared with a dry laminating process, the laminating process uses the optical adhesive film, so that the process flows of manufacturing an OCR adhesive layer and the like in the early stage are replaced, and the manufacturing process is simplified; in addition, compared with the existing OCR material, the optical adhesive film used in the process does not need reinforcement, so that the production efficiency is further improved; the product laminating can be completed only by two laminating machines and a defoaming machine in the laminating process, the existing dry glue process needs a glue mixing machine, a glue dispensing machine, a knife coating machine, a heating platform, a laminating machine and a defoaming machine, the equipment investment cost is higher, and the occupied area of a laminating line body is larger. Contrast wet-type laminating, wet-type laminating needs the box dam to glue, and OCR coating process needs very accurately to the point volume of gluing of colloid control, and the equipment required precision is higher to the point, has the excessive gluey problem in the product laminating in-process in addition, and the clean degree of difficulty in later stage is big. The optical adhesive film adopted in the application does not need to control the dispensing amount of the adhesive, so that the problems are completely avoided, the process is simplified, and the problem of adhesive overflow is solved. Compared with the traditional OCA (optically clear adhesive) attaching process, the main difference is that ultraviolet light secondary curing is needed after the existing OCA is attached, so when some cover plates with the surface provided with the blocking agent are used, ultraviolet light cannot irradiate the inner side of the cover plates, and the material cannot exert all the performances of the cover plates; the optical adhesive film in the application does not need ultraviolet light for secondary curing, so that the adhesive film is wider and unlimited in substrate bonding selection.
This application detects optical cement membrane surface through cubic element measuring apparatu and has or not stripe, pit, foreign matter. A three-dimensional measuring instrument mainly refers to an instrument for measuring by taking points in three dimensions, and three-dimensional measuring machines, three-dimensional measuring instruments and three-dimensional measuring instruments are also available on the market. The main principle is as follows: the measured object is placed in a three-dimensional measurement space, the coordinate position of each measuring point on the measured object can be obtained, and the geometric dimension, the shape and the position of the measured object are calculated according to the space coordinate values of the points. The basic principle is that through the matching of the detection sensor (probe) and the movement of the measurement space axis, the discrete space point position of the measured geometric element is obtained, then through certain mathematical calculation, the analysis fitting of the measured point (point group) is completed, finally the measured geometric element is restored, and on the basis, the deviation between the measured geometric element and a theoretical value (nominal value) is calculated, so that the inspection work of the measured part is completed. According to the method, whether the thickness of the optical adhesive film is qualified or not is measured through the laser height measuring instrument, and if the thickness of the optical adhesive film is not qualified, the optical adhesive film is reselected. The laser altimeter in the application is an instrument for measuring the thickness of a target by using a certain parameter of modulated laser. The distance measuring method includes phase distance measuring instrument and pulse distance measuring instrument, the pulse laser height measuring instrument emits one or several short pulse laser beams to the target during operation, the photoelectric element receives the laser beam reflected from the target, and the timer measures the time from emitting to receiving of the laser beam to calculate the thickness of the target. The phase method laser altimeter detects the thickness by detecting the phase difference generated when the emitted light and the reflected light propagate in the space. The laser height measuring instrument has light weight, small volume, simple operation, fast speed and accuracy, and the error is only one fifth to one hundreds of that of other optical distance measuring instruments, thereby bringing great convenience to measurement.
