Embodiment 1
[0020] Such as figure 1 , figure 2 and image 3 As shown, a method for correcting the position of the capacitive screen 1 and the OCA film 2 in the present invention includes a process of adjusting the relative position between the capacitive screen carrying platform 3 and the film carrying platform 4. The capacitive screen carrying The platform 3 is a three-axis platform, and the film carrying platform 4 is a single-axis platform, wherein, in the process of adjusting the relative position between the capacitive screen carrying platform 3 and the film carrying platform 4, an industrial camera 5 is used to Shoot the adhesive film 2 on the adhesive film carrying platform 4, utilize the computer detection that is arranged on the reference point on the adhesive film 2 to coordinate with the computer detection that is connected with the described industrial camera 5, take the turning axis of the adhesive film carrying platform 4 as the axis of symmetry , take the symmetry point ...

A method for correcting a position before the lamination between a capacitive screen and an OCA glue film comprises a process of adjusting a relative position between a capacitive screen bearing platform and a glue film bearing platform, wherein the capacitive screen bearing platform is a three-axis platform, and the glue film bearing platform is a single-axis platform. An industrial camera is utilized to shoot materials on the glue film bearing platform and detect the field-of-view coordinates of two reference points. The turning shaft of the glue film bearing platform is taken as a symmetric axis and the symmetric points of the field-of-view coordinates of two reference points are taken as the field-of-view coordinates of the two reference points after the glue film is turned to the capacitive screen bearing platform so as to convert the correction problem of the glue film bearing platform into the correction problem of the capacitive screen bearing platform, and the capacitive screen and the glue film are corrected by the three-axis platform; moreover, because the accuracy of three-axis correction is far higher than the accuracy of single-axis correction, the accuracy of the lamination is improved greatly.
Description
Technical field: [0001] The invention relates to the field of electricity, in particular to a film-attaching technology of a capacitive screen, in particular to a method for correcting the position of a capacitive screen and an OCA adhesive film before bonding. Background technique: [0002] In the prior art, the process flow of bonding capacitive screen and OCA film is as follows: the three-axis platform loaded with capacitive screen moves to the bonding calibration position, the single-axis platform loaded with OCA material moves to the bonding calibration position, and the single-axis platform turns over Paste the OCA film on the capacitive screen. Since loading and transmission will cause errors in the position of the loaded material, it is necessary to correct the position of the material to the calibration position before lamination. Generally, it is necessary to correct the front-to-back deviation, left-right deviation and rotation angle of the material, but the sing...
