Embodiment Construction

[0038] Such as figure 1 Shown, in one embodiment, a kind of pre-lamination method of glass substrate, comprises the steps:

[0039] Step 110, fixing the lower glass substrate by adsorption.

[0040] In this embodiment, the lower glass substrate is placed on the supporting motion platform of the sealed chamber, and the vacuum pump is turned on to evacuate the sealed chamber where the lower glass substrate is located, so that the lower glass substrate is adsorbed and fixed on the supported moving platform.

[0041] Step 130 , placing the upper glass substrate on the adsorption-fixed lower glass substrate.

[0042] In this embodiment, the upper glass substrate is vacuum-adsorbed by the manipulator, and the upper glass substrate is moved to a preliminary position above the lower glass substrate that is adsorbed and fixed.

[0043] Step 150 , receiving laser light that sequentially passes through the dot marks on the lower glass substrate and the upper glass substrate.

Abstract

The invention provides a glass substrate pre-laminating method and a glass substrate pre-laminating system. The glass substrate pre-laminating method comprises the following steps: adsorbing and fixing a lower glass substrate; putting an upper glass substrate above the adsorbed and fixed lower glass substrate; receiving laser successively penetrating dot marks on the lower glass substrate and then penetrating the upper glass substrate; judging if a picture formed by the laser is consistent to the dot marks on the upper glass substrate; and if the picture formed by the laser is consistent to the dot marks on the upper glass substrate, vertically moving the upper glass substrate onto the lower glass substrate. According to the glass substrate pre-laminating method, the cost is reduced, and rapid alignment can be realized.

Description

technical field [0001] The invention relates to laser packaging technology, in particular to a pre-lamination method and system for glass substrates. Background technique [0002] Before laminating the glass substrates, it is often necessary to accurately align the two glass substrates. In the traditional alignment process of glass substrates, most of them use CCD cameras to collect images, and then process the collected images to determine the two glass substrates. Whether the glass substrate has been aligned. [0003] The accuracy of glass substrate alignment will depend on the accuracy of the CCD camera, and the higher the precision of the CCD camera, the more expensive it is, and this traditional glass substrate alignment cannot achieve two pieces of glass due to the need for additional image processing. For rapid alignment of substrates, the traditional glass substrate alignment method has the defects of high cost and low efficiency. Contents of the invention [000...
