Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 and figure 2 The lens module 200 tested by the assembled testing device 100 provided by the present invention includes a lens barrel 210 , a first lens 211 , a second lens 212 , a third lens 213 , a first spacer ring 214 and a second spacer ring 215 .

[0015] The first lens 211 , the first spacer ring 214 , the second lens 212 , the second spacer ring 215 and the third lens 213 are sequentially accommodated in the lens barrel 210 from the object side to the image side. The first lens 211 , the second lens 212 and the third lens 213 are all formed by injection molding, and the edges of the first lens 211 , the second lens 212 and the third lens 213 all have gate traces 211 a , 212 a and 213 a. The gate traces 211a, 212a and 213a all point to the same radial direction. The first lens 211 can move radially relative to the second lens 212...

Abstract

The invention provides an assembling and testing device, comprising a movement mechanism, an image sensor and a controller; the assembling and testing device is used for assembling and testing multiple lens modules; the inner part of the lens module is orderly provided with a first lens and a second lens from the object side to the image side; the second lens is fixed in the lens module and the first lens can move opposite to the second lens in the radial direction; the controller comprises a locating module for controlling the movement mechanism to radially move the first lens to a position as a primary position, an acquiring module for acquiring the image sensed by the image sensor, an adjusting module for controlling the movement mechanism to move the first lens and enable the first lens to be not eccentric relative to the optical axis of the lens module according to the image, a memory module for recording the movement process of the movement mechanism, a control module for controlling the movement mechanism to move the first lens of an other lens module according to the recorded moving process of the movement mechanism. The assembling and testing device provided by invention adjusts the eccentricity according to the record, thus saving time; in addition, the invention also provides an assembling and testing method.

Description

technical field [0001] The invention relates to an assembly testing device and method. Background technique [0002] With the continuous development of digital technology, digital cameras have been widely used by people, especially in recent years, portable electronic devices such as mobile phones and PDAs (Personal Digital Assistants, personal digital assistants) are also rapidly developing in the direction of high performance and multifunctionality. The combination of cameras and these portable electronic devices has become the key to the development of mobile multimedia technology. [0003] Since the lens module integrated in the portable electronic device is much smaller than the lens of the camera, higher requirements are placed on the optical performance. For a lens module with multiple lenses, it is necessary to ensure that the optical centers of the lenses are on the same optical axis. In particular, the accuracy of the relative position between the first lens and ...
