Abstract

A lens adsorption jig for active alignment of an image module and its method. The jig is suitable for being operable to be connected to a vacuum device to assemble and correct an image module. It includes a connection device and an adsorption device. The connection device has a channel, the channel has a first gas port, which is suitable for gas communication to the vacuum device, the adsorption device is connected to the connecting device, and has at least one second gas port and an inner cavity, the inner cavity is at the adsorption end of the adsorption device There is an opening, and the second air port is connected to the channel. When the vacuum device generates vacuum pressure, the opening of the suction device faces the lens of the image module and enables the suction device to absorb the lens.

Description

technical field [0001] The invention relates to the field of jigs, in particular to a jig that can perform actions including assembling, calibrating, and moving an image module by adopting an adsorption method. Background technique [0002] With the popularization of smartphones and tablets, coupled with the demand for Internet of Things applications that have become popular in recent years, the demand for imaging modules with camera capabilities is increasing for devices, especially handheld and wearable devices that are becoming thinner and smaller. , while trying to reduce the size, it is required to improve the precision and accuracy to provide high-resolution cameras that are indispensable in many device applications. [0003] Therefore, in order to quickly mass-produce such small-volume precision image modules, the manufacturing process and fixtures used by the factory must also continue to improve. Active Alignment (AA) technology, which has been widely used since the...
