[0019] see figure 1 and figure 2 shown, where figure 2 for figure 1 An enlarged schematic of part A. The first embodiment of the present invention provides an image capture module M with a built-in dustproof structure, which includes: an image sensing unit 1 , a frame case 2 and an actuator structure 3 .

[0020] First, if figure 1 As shown, the image sensing unit 1 includes a carrier substrate 10 and an image sensing chip 11 disposed on the carrier substrate 10 and electrically connected to the carrier substrate 10 . For example, the image sensing chip 11 can be a CMOS image sensing chip, and the image sensing chip 11 can be provided with an adhesive (not numbered, such as UV adhesive, thermosetting adhesive, or furnace curing adhesive, etc.) on the carrier substrate 10 . In addition, the carrier substrate 10 can be a circuit substrate with a plurality of conductive pads (not labeled) on the upper surface, the upper surface of the image sensing chip 11 has a plurality...

Abstract

Provided is an image acquisition module with a built-in dustproof structure, comprise an image sensing unit, a framework housing and an actuator structure. The image sensing unit comprises a bearing substrate and an image sensing wafer. The framework housing is arranged on the bearing substrate and encircles the image sensing wafer. The actuator structure is arranged on the framework housing and above the image sensing wafer, and comprises a lens holder arranged on the framework housing, and a movable lens module capable of being movably arranged in the lens holder. The internal surrounding surface of the lens holder is provided with a first surrounding structure, and the periphery of the movable lens module is provided with a second surrounding structure arranged above the first surrounding structure. The first surrounding structure of the lens holder is in cooperation with the second surrounding structure of the movable lens module so as to form a built-in dustproof structure.

Description

technical field [0001] The invention relates to an image capture module, especially an image capture module with a built-in dustproof structure. Background technique [0002] In recent years, it has become increasingly common for handheld devices such as mobile phones and PDAs to be equipped with imaging modules. With the market demand for better functions and smaller volumes of handheld devices in the product market, imaging modules have become Facing the dual requirements of higher image quality and miniaturization. For the improvement of the image quality of the imaging module, on the one hand, it is to increase the pixels. The market trend is from the original VGA level of 30 pixels to the common 2 million pixels, 5 million pixels, and 1300 pixels in the market. 10,000 pixels, and even higher levels of 41 million pixels or more have been introduced. In addition to the improvement of pixels, another concern is the clarity of image capture. Therefore, the image capture m...
