BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera lens assembly, and more particularly, to a camera lens assembly assembling apparatus and an assembling method thereof, which can be assembled without expensive assembling equipment.

2. Description of the Related Art [0002] With the advent of compact and lightweight camera lens assemblies due to the development of digital camera manufacturing technology, portable communication apparatuses equipped with optical lenses and camera lens assemblies have become popular .

The camera lens assembly is miniaturized to be mounted on a portable communication device, and the camera lens assembly must be constructed in a structure capable of properly implementing performance even in a miniaturized state. An important factor along with the magnification that determines the performance of the camera lens assembly is resolution. When the resolving power is improved, the image of the subject becomes clear, and even a detailed portion can be observed. The camera lens assembly can adjust the focal distance, which is the distance between the image sensor and the lens, and the camera lens assembly can maximize resolution at the optimum focal length.

As shown in FIG. 1, the structure of the camera lens assembly 1 will be described below. The camera lens assembly 1 includes a printed circuit board 2 having an image sensor 2a, a base 3 having an engagement groove 3a opened in the optical axis direction, A driving unit 5 for driving the lens assembly 4 in the optical axis direction and a cover unit 7 coupled to an upper portion of the base 3, .

1, the driving unit 5 includes a lens assembly 4 having a magnetic body 4b and a supporting member 4c, and a lens assembly 4 provided in the driving unit 5 and corresponding to the magnetic body 4b A coil part 8 for generating driving force, a pair of guide parts 6 for guiding the driving of the lens assembly 4, and a position sensing part 9 provided in the driving part. The position sensing sensor 9 is a hall sensor for sensing a change in the position of the magnetic body 4a. A plurality of balls 6a are formed between the guide portions 6 and the support members 4c and the support members 4c are disposed to face the guide portions 6, 6a of the guide portion 6, as shown in Fig.
