Another object of the present invention is to provide a method for assembling a digital camera lens module which is simple in assembly and high in cleanness in the lens. [0007] The digital camera lens module of the present invention comprises: a lens barrel, a lens holder having a pin hole on a circumferential wall of the lens barrel, the lens holder having a sleeve, the lens barrel being received in the sleeve Inside, the sleeve wall is provided with an elongated groove, and the starting and ending points of the elongated groove have relative displacement along the axial direction of the sleeve. The method for assembling a digital camera lens module of the present invention comprises: providing a digital camera lens module, the digital camera lens module comprising a lens barrel and a lens holder, the lens barrel having a pin hole on the circumferential wall; the mirror The sleeve has a sleeve groove wall with an elongated groove, the elongated groove (4) and the end point have a relative displacement along the axial direction of the sleeve; the lens barrel is placed in the sleeve of the lens holder, and the pin hole pair of the lens barrel An elongated slot on the lens holder; provided with a latch, the latch is inserted into the pin hole through the elongated slot, the rail is held at the bottom end, and the other end is exited from the elongated slot, and the latch is pulled along the elongated slot Slide, the pin drives the lens barrel to rotate; dispense the lens holder and the lens barrel.闺 Compared with the prior art, the digital camera module of the present invention has simple mold making during processing, and the method of assembling the digital camera lens module adopts the cooperation of the pin and the elongated groove to realize the adjustment of the lens barrel. The upper and lower displacements' structure is relatively simple, and in addition, the assembly method reduces the ashing of the contact surface due to wear. 093122050 Form No. A0101 Page 4 of 11 0993227784-0 1332112 [Embodiment] Please refer to the first figure, the lens holder 20. June 18, 2008, the invention of the digital camera lens module includes a lens barrel 1 [0011] [0013] The lens barrel 10 has a cylindrical barrel 1 〇 1 for receiving a plurality of optical bodies A lens (not shown) that converges light from an image. The cylindrical wall of the barrel body 101 has a pin hole 1〇2 which is a cylindrical hole, generally preventing dust from entering, and avoiding damage to the plurality of optical lenses in the barrel 101. The pin hole 102 only penetrates the barrel body 1〇1 Part of the wall. The end of the lens barrel 10 is an open end, a plurality of lenses are mounted from the end, and the other end is a semi-closed end that allows light to enter the human body. The semi-closed end has a protective window 1G3 _, which is a transparent window, not only The light from the shadow film enters the lens barrel 10 from the protective window 103 while protecting the optical lens in the lens barrel 10' to prevent dust from entering. The lens holder 20 has a base 201 that houses an image sensing element (not shown). - Usually the image sensing element is a charge coupler (charge

Coupled

Device 'hereinafter referred to as CCD> or a Complementary Meta-Oxide-Semiconductor (hereinafter referred to as CMOS)» extends from the base 201 to a cylindrical sleeve 202, which accommodates the lens barrel 10 The barrel ιοί, the barrel ι 〇 1 and the sleeve 2 〇 2 clearance fit, they can rotate relative to each other. An elongated slot 203 is formed in the wall of the sleeve 2〇2, and the starting and ending points of the elongated slot 203 have a relative displacement in the axial direction of the sleeve 202. The trajectory of the elongated slot 203 is a smooth curve extending upwardly along the wall of the sleeve 202, which makes the relative position adjustment of the lens barrel 10 and the lens holder 2 更为 more stable. The base 201 is fixedly connected to the mobile phone body (not shown). 093122050 Form No. A0101 Page 5 of 11 0993227784-0 1332112 I June 28, 2008 Dad [0014] When the lens barrel 10 and the lens holder 20 are assembled, the focal length is adjusted by the pin 3〇. The pin 3 has a columnar shape with one end engaged with the pin hole and the other end exposed from the elongated groove 203. The pin 3 has a diameter smaller than the width of the elongated groove 2〇3, which is slidable along the elongated groove 203.

[15] For the assembly method of the digital camera module, please refer to the second figure, the lens barrel 1〇 is placed in the sleeve of the lens holder 20, and the pin hole 102 of the lens barrel faces the elongated slot 203 of the lens holder 2 The pin 3 is inserted into the pin hole 1〇2 through the elongated slot 2〇3 so that the end of the pin 30 abuts against the bottom end of the pin hole 102, and the other end is exposed from the elongated slot 2〇3. When the focal length is adjusted, the latch 30 is toggled. Since the latch 3 is limited to the elongated slot 203, the latch 30 can only slide along the elongated slot 2〇3, and the latch 3〇 is fixed relative to the lens barrel 1 , while driving the lens barrel. When the 丨〇 is rotated, the lens barrel 向上 moves up or down in the axial direction to change the distance between the lens and the image sensing element to achieve the adjusted focal length. After adjusting to the predetermined focal length, the top of the county can 202 is in contact with the barrel 101, and glue is applied to fix the relative position of the lens barrel 10 and the lens holder 2, and the latch 30 can be removed. [0016] It is understood that the dispensing method can also symmetrically open a plurality of holes (not shown) on the circumference of the sleeve 202. After adjusting to a predetermined focal length, glue the plurality of holes to fix the lens barrel 1 and The mirror base is 2 inches. [0017] It can be understood that the trajectory of the elongated groove 203 on the wall of the sleeve 202 may be other regular or irregular curve shape as long as the starting point and the end point of the curved shape are relatively displaced along the axial direction of the barrel 101. [0018] It can be understood that the digital camera lens module of the present invention and the assembly method thereof can also be applied to portable electronic devices such as projectors and cameras. [〇〇19] In summary, the present invention complies with the requirements of the invention patent, and patents are filed according to law. 093122050
