Description of the invention: [Technical field to which the invention pertains] 5 ❹ 10 15 ❹ 20 The present invention relates to a lens module. More specifically, the present invention relates to a technique for correcting the focal length of a lens module, and the lens module can be applied to an image capturing device such as a digital camera. Micro, [Prior Art] With the popularity of digital video, the demand for digital cameras, digital video cameras, and multi-function mobile phones that provide camera functions is also increasing in the global market. The key module of the versatile mobile phone that provides camera functions includes a compact camera module (CCM). In general, a miniature camera module includes an AFactuator, a lens assembly, a sensor, and a shutter assembly. Since the purpose of use is mostly portable, the miniaturization of the overall structure is very demanding. Among them, the lens assembly is composed of a plurality of lenses for focusing the light on the sensor. For the purpose of smooth focusing, the lens assembly and the sensor are usually arranged along the optical axis, and the spacing and parallelism between the lens assembly and the sensor have a great influence on the sharpness of the image. FIG. 1 is an exploded view of a conventional lens module 100. The lens module 100 includes: a sensor 20 for detecting an image to generate an electrical signal, the sensor 20 is disposed on a carrier 10; a lens assembly 50' includes a plurality of mirror months (not shown ) for accommodating the sensor 20 and a bearing area of the carrier and a connecting device 70 between the sensor 20 and the lens assembly 50 for connecting the carrier 10 to the carrier On area 60. The sensor 20 and the lens 6 200930068 assembly 50 may further include an elastic rubber 30 and a glass 40 for stopping. In general, there are two common factors that can cause poor image clarity. One of them is that the distance between the lens assembly and the sensor is too large or too small, so that the light cannot be smoothly focused on the sensor. The other is that the level between the lens unit and the sensor is not good, causing the light to pass through the lens in the lens assembly and deviate from the optical axis, which also causes the image to become blurred. In the conventional lens module shown in Fig. 1, the image must be blurred without being accurately controlled by machining precision and assembly error. In order to improve the shortcomings of this type of lens module, it is also known to install the sensor on an adjustment device first, and then fix the image after the image is adjusted to the best. However, the size of such adjustment devices is too large, which is rather disadvantageous for products requiring a much smaller miniaturization of the overall structure. In order to solve the problems that the prior art cannot solve, it is desired to have a new and improved lens module that can optimize the spacing and parallelism between the lens assembly and the sensor by using an adjustment device. It does not increase the overall volume of the lens® module.
