[Previous Technology] [0002] With the continuous development of technology, portable electronic devices such as mobile phones have a wide range of applications, and at the same time, they are becoming lighter, more beautiful and more multifunctional. Among them, the camera function is a popular mobile phone in recent years. Additional features. The digital camera module to be used in mobile phones must not only meet the requirements of lightness and thinness, but also must have good photographic performance. The digital camera lens module assembly method is one of the main factors determining the photographic performance. Especially in the assembly process of the digital camera lens module, the assembly process should be considered to facilitate mass production, reduce costs, and also need to consider the assembly structure may cause The contamination of the lens, therefore, the improved assembly method will effectively improve the imaging performance of the digital camera module. A conventional digital camera lens module includes a lens barrel and a first lens, a spacer ring and a second lens held in the lens barrel. A stop ring is protruded from the inner wall of the lens barrel adjacent to one end thereof. The first lens, the spacer ring and the second lens are sequentially received in the lens barrel and the first lens abuts the stop ring. The spacer ring is used to isolate the first lens from the second lens such that the first lens and the second lens are spaced apart to meet the optical design requirements of the digital camera lens module. When the digital camera lens module is assembled, the first lens and the spacer ring are usually placed in the lens barrel in sequence, and then a glue injection device having a needle-like injection portion is used to move the spacer ring away from the surface of the first lens 095108177. Form No. A0101 Page 4 of 17 1003391230-0 1354858 On October 21, 100, apply UV glue (Ultraviolet glue) on the outer circumference of the replacement page, press it into the second lens, and then use UV light. The UV glue is cured by irradiation to fix the second lens in the lens barrel, thereby fixing the components in the lens barrel between the stop ring of the lens barrel and the second lens. In order to fix the second lens in the lens barrel more stably, the glue is usually dispensed on the surface of the spacer ring. Therefore, it is necessary to relatively rotate the lens barrel and the glue applicator to dispense a plurality of places, thereby causing the digital camera lens. The module assembly process takes a lot of time. In addition, the dispensing amount of the glue injection device is not easy to control. On the one hand, when the second lens is assembled, the phenomenon of overflowing glue is easy to occur, thereby affecting the image quality of the entire lens; on the other hand, it is easy to cause the amount of dispensing everywhere. The unevenness causes stress on the bonding between the second lens and the lens barrel and the spacer ring. Under long-term use, the second lens is detached from the lens barrel and the spacer ring, and the camera lens module cannot be used. SUMMARY OF THE INVENTION [0004] In view of the above problems, it is necessary to provide an improved spacer ring for a camera lens which can prevent the glue from contaminating the lens. [0005] It is also necessary to provide an improved camera lens in which the inner lens is less susceptible to contamination by the glue and reduces the stress between the lens and the spacer ring and the lens barrel. [0006] It is also necessary to provide a camera lens assembly method. Dispensing evenly and shortening assembly time.

Extending to the lower surface 31 2 of the injection portion 31 to form a plurality of glue outlets 317, the lower surface 31 2 also protruding a convex ring 319 which cooperates with the annular groove 23 of the spacer ring 20; [0029] Step 5: The glue applicator 30 is inserted into the lens barrel 11 so that the convex ring 319 of the injection portion 31 is received in the annular groove 23 of the spacer ring 2, and the glue outlet 317 is adjacent to the periphery of the top surface 201 of the spacer ring 20 and the lens barrel. 11 inner wall, lower surface of injection portion 31 312 095108177 Form No. A0101 1003391230-0 1354858 __·_ October 2nd, 2nd day, there is a gap between the replacement page and the top surface 201 of the spacer ring 20; [0030] Step 6: Driving control device The piston portion 33 of the driving glue applicator 30 is moved to press out an appropriate amount of adhesive 37 on the periphery of the top surface 201 of the spacer ring 20; [0031] Step 7: remove the glue applicator 30; [0032] Step 8: Provide a second lens 13 The second lens 13 is pressed into the lens barrel 11 to abut against the spacer ring 20, and the second lens 13 is fixed to the top surface 201 of the spacer ring 20 and the inner wall of the lens barrel 11 by the adhesive 37. [0033] The assembly of the camera lens 10 can be completed. If more lenses need to be loaded, repeat steps 3 through 8. [0034] The lens spacer ring 20 is provided with a ring groove 23. If the glue 37 has too much glue, when the lens 13 is pressed into the lens 13, the glue can be placed in the ring groove 23 to prevent the glue from being contaminated. A lens 12 and a second lens 13 ° [0035] The glue injector 30 used in the camera lens assembly method of the present invention is provided with a plurality of glue outlets 317, which can complete multiple dispensing at the same time, and the dispensing position is evenly distributed. The dispensing amount is equivalent, the assembly time of the camera lens 10 can be saved, and the stress generated by the unevenness of the dispensing amount between the second lens 13 and the spacer ring 20 and the inner wall of the lens barrel 11 can be reduced. [0036] In summary, the creation complies with the new patent requirements, and the patent application is filed according to law. However, the above-mentioned ones are only preferred embodiments of the present invention. Those who are familiar with the art of the present invention, and equivalent modifications or changes made in the spirit of the present invention should be included in the following patent application.
