Description

Automatic burning machine for camera module group testing

Technical Field

The invention relates to the technical field of camera module assembly measurement and automation, in particular to an automatic burner for camera module assembly measurement.

Background

Along with the continuous perfection of intelligent product function, the camera module becomes one of the main component parts of mobile terminal, and the performance test of camera module before installation is the important process of guaranteeing the photographic function of follow-up mobile terminal. In this procedure, the camera module is connected to the external test device through the module connector to complete performance detection and OTP recording (performance detection and OTP recording may also be referred to as assembly test of the camera module). In the prior art, 1 usually needs to detect parameters such as dead pixel, color, brightness uniformity, white balance, optical center, stripe, dark edge, and RUCU of the mobile phone camera, then adjust parameters according to the detection result, and burn corresponding programs based on the adjusted parameters (i.e. burn corresponding programs into firmware of the mobile phone camera).

On the other hand, since the camera module generally needs to pass through the detection of multiple test links, one camera module to be detected may need to be connected with multiple external test devices, which results in that the camera module connector needs to be plugged and unplugged multiple times during the test process. The camera module connector has extremely small volume, dense interface pins and easy damage caused by frequent plugging and unplugging of the camera module connector. Based on this, the applicant has proposed a special carrier (usually a PCB board) to plug in the connector of the camera module, so that the external test device can be plugged in the special carrier to be electrically connected with the camera module to be burned or tested. The dedicated carrier is sometimes also referred to as an adapter (or adapter plate).

Currently, the iteration speed of products in the consumer electronics terminal market (such as the mobile phone market) is high, and higher requirements are put on production efficiency, for example, the requirements on the yield of the designed and shaped camera module are sometimes more than tens of millions, and the huge number of products may need to be produced, OTP burned and inspected in a very short time so as to meet the yield requirement of the hot-selling mobile phone. Therefore, it is easy to understand that the production efficiency is an important index for the camera module. For mass production of products, the production efficiency is very disadvantageous. However, the conventional burner usually adopts a serial manner to sequentially detect the different parameters, and finally performs the program burning. In the existing equipment, a conveyor-based assembly line is generally adopted to realize the circulation of the to-be-detected or to-be-burned camera module, and the conveyor-based assembly line has long circulation time and huge equipment volume. If a single device is used for detecting and burning the camera module, each procedure can only be executed in series. That is, when any one link is performed, the other links are all in a waiting state. This will result in serious equipment idling, low throughput and high equipment cost.

On the other hand, in order to improve the production efficiency, the applicant has proposed a solution of splicing, i.e. combining a plurality of (for example, 16) fastened carriers (i.e. carriers fastened with camera modules) into one splicing board, wherein the camera modules can be distributed in an array in the splicing board, and the feeding and discharging and the energizing test of each performance are performed based on the whole splicing board. Therefore, a plurality of camera modules can be tested at the same time, and the production efficiency is greatly improved. However, in the case of tiling, it is desirable to use a physical, reversible panel in order to join multiple carriers together. A large number of solid panels are reused in the circulation process, and some of the panels may have bending or other reliability problems, which may cause failure of the test line, thereby reducing production efficiency and increasing maintenance cost.

On the other hand, in order to improve the production efficiency, the applicant has also proposed a parallelization solution, i.e. integrating a plurality of test links into one rotary test device. For example, stations may be respectively disposed in four directions of the rotary apparatus, wherein three stations are test stations, and one station is loading and unloading stations. Like this, different test stations can carry out the circular telegram test to a plurality of makeup (refer to the makeup of carrying on a plurality of modules of making a video recording) simultaneously to realize the parallelization that the module of making a video recording detected. However, the degree of parallelization of existing rotary test equipment is still to be further increased. For example, the loading and unloading process is difficult to perform well in parallel with the testing process. As another example, test cartridges of a rotary test apparatus that are positioned in four directions all require wires to be connected to complete a power-on test, however as the rotary test apparatus is continuously rotated, the wires may become entangled with each other, resulting in the rotary test apparatus having to be reset after a period of operation (i.e., rotated in the opposite direction to release the entangled wires). The above problems not only increase the hidden trouble, but also reduce the production efficiency (because the test work cannot be performed in the resetting process). For another example, in the conventional rotary test apparatus, the camera module or the carrier on which the camera module is mounted needs to be mounted on the rotatable board in advance, and this process needs to be completed manually or using another special apparatus. As described above, the manual operation has low working efficiency, high labor intensity, unstable working quality, and the like. And use another professional equipment to install the module of making a video recording or carried the carrier of making a video recording the module and to can circulate on the makeup, then can increase equipment quantity, lead to occupation area to increase, the yield of unit area reduces, manufacturing cost increases scheduling problem.

Therefore, there is an urgent need for an automatic burning solution for camera module assembly with high parallelization degree, low failure rate, and contribution to further improving production efficiency.
