Automatic gluing system and gluing method thereof

Abstract

The invention relates to an automatic gluing system and a gluing method thereof. The automatic gluing method comprises the following steps: S100) transformation constants of pixel coordinates and machinery coordinates of a target object can be obtained by a machinery vision unit; S200) a pin position is corrected by a pin calibration unit, a pin gluing original point is set; and S300) gluing visual image is registered by a glue line drafting unit for drafting the coordinate of the glue line path.

Description

technical field [0001] The invention relates to a gluing system, in particular to an automatic gluing system controlled by machine vision and a gluing method thereof. Background technique [0002] In the mobile phone camera module (CCM) industry, optical products are developing towards miniaturization, light weight and high precision, and the quality of optical devices is becoming more and more strictly controlled. As the pixels of mobile phone modules continue to increase, the light sensitivity is also required to continue to increase. The market is increasingly pursuing mobile phones that capture high-definition images. In the common manual production mode, the assembly of the mobile phone camera module is to manually adjust the positions of the lens motor module (VCM) and the photosensitive chip (SENSOR) in the camera module, so that the lenses installed in the lens assembly, The geometric optical axis center of optical lenses such as optical filters is aligned with the ...

In the common manual production mode, the assembly of the mobile phone camera module is to manually adjust the positions of the lens motor module (VCM) and the photosensitive chip (SENSOR) in the camera module, so that the lenses installed in the lens assembly, The geometric optical axis center of optical lenses such as optical filters is aligned with the center of the photosensitive element of the image module. However, due to operational errors, the lens and photosensitive chip may cause the optical center of such axisymmetric optical components to appear when the system is assembled. Offset, there are positional accuracy deviations such as tilt (Tilt) and offset (Shift) between the lens and the photosensitive chip, which have a serious impact on the imaging quality of the module, resulting in a continuous decline in product yield

[0003] At present, the packaging process (COB) of th...
