Description

Full-automatic double-station multi-group AA equipment of camera

Technical Field

The invention relates to the technical field of camera assembly, in particular to a full-automatic double-station multi-group AA device of a camera.

Background

The last decade is the prime time for smart phone development, and the mobile phone camera market is rapidly growing along with the growth of terminals. The camera is also upgraded from the original pixel to the subsequent function upgrade; the single shot changes into multiple shots, and the ultra-wide angle and large aperture continuously emerge; the improvement of the changes brings different high-quality experiences to vast mobile phone users, increases more choices, and even then, the continuous pursuit of the vast users for the functions of the camera cannot be stopped.

Under the environment of the market appeal, "digital zooming" and "optical zooming" appear silently in the brand release meetings of numerous smart phones, and attract the favor of a large number of users. The greatest change is that digital or optical zooming is realized by a certain technical means, so that the camera can achieve the function of 'taking a long shot', namely a long-focus camera; however, with the continuous updating of the telephoto lens, many terminal mobile phones can achieve 2X, 3X, 5X, and even 10X zoom, and then a "periscopic camera" appears. These are all the upgrading and reconstruction of camera structure and the related camera packaging technology all have higher requirements.

In the camera assembling process, multiple assembling of parts such as an image Sensor (Sensor) and a Lens (Lens) is involved, and conventional assembling devices such as a CSP and a COB perform moving assembling of the parts according to parameters adjusted by the devices (Passive Alignment technology). Therefore, the superposition tolerance of the spare and accessory parts is increasingly larger, and the effect finally shown on the camera is that the clearest position of a photographed picture can deviate from the center of the picture, the definition of four corners is not uniform, and the like.

The AA process, Active Alignment, is interpreted as chinese, which is an Active Alignment, and is a technique for determining the relative position of parts during the assembly process. In the AA process apparatus, when assembling each component, the equipment will detect the assembled semi-finished product, actively align the semi-finished product according to the actual situation of the assembled semi-finished product, and then assemble the next component in place. The active alignment technology can adjust the lens alignment to 6 degrees of freedom (X, Y, Z, Tx, Ty and Tz), effectively reduce the assembly tolerance of the whole module, effectively improve the consistency of camera products, and create possibility for higher-order camera product packaging. When the Sensor and Lens are assembled, the relative X-axis, Y-axis, Z-axis, Tx-axis, Ty-axis and Tz-axis 6 degrees of freedom of the Sensor and Lens are required to be ensured to be at the optimal position so as to ensure that the optical axes of the Sensor and Lens are coaxial.

The existing AA (advanced video camera) manufacture procedure of the camera realizes precise focusing by one lens part and one Sensor part, but the periscopic camera has further requirements on the AA manufacture procedure due to the complex optical path and the compact structural design, and compared with the conventional camera, the assembly process of the whole camera can be completed by a plurality of AA manufacture procedures. In the process of multiple AA processes, the finished camera cannot meet the expected design requirements due to excessive turnover and process conversion.
