Abstract
An image module comprises a lens seat, a lens and a substrate. The lens seat is of a hollow structure. An inner wall is arranged in the lens seat. Outer threads are arranged outside the lens. Inner threads matched with the outer threads are arranged on the inner wall of the lens seat. The lens is arranged in the lens seat in a screwing in mode. Thread clearance exists between the outer threads and the inner threads. The substrate, the inner wall and the bottom of the lens form a containing cavity. The substrate seals the bottom of the lens seat. An exhaust groove is formed in the inner wall and is communicated with the thread clearance and the containing cavity. Compared with the mode of an air escape hole in the traditional technology, the image module exhausts through clearance between the lens and the inner threads and the outer threads of the lens seat in an exhaust groove mode, saves the cost of secondary utilization of sealants, saves baking time, improves production efficiency, and saves cost. The exhaust groove is formed in the lens seat so as to prevent powder and dust from flowing onto a chip. Consequently, pollution can not be caused, and image effect can not be influenced.
