[Prior Art] ^The lens module applied to a camera or optical instrument usually consists of a lens barrel and a lens holder with optical components. Referring to FIG. 1 , a lens module includes a lens barrel 1 , a lens group n , a spacer ring 12 , and a filter 13 , wherein the lens group 11 , the interval % 12 , and the filter 13 along the optical axis The direction is fixed in the mirror 10, and the filter 13 is disposed in the assembly process of the lens barrel 10 near the outermost lens module of the object to be illuminated. And loaded with parts, such as filter, light sheet is fixed on the inner wall of the lens barrel. Specifically, the glue is applied to the spacer ring 22 by drop using a small device, and the light-sensitive sheet 23 is adhered to the spacer ring 22 by the glue. However, there are many problems in automated dispensing, such as point (four) set multiple times = politics is not only time-consuming, but also easy to cause the dispensing device to be inaccurate, the mouth: = and: the quality of the dispensing glue will be directly Affects the dropout of the filter in the lens module lens module. In the second reason of the mirror - do not fix the calender sheet on the inner wall of the lens barrel, the assembly process, the special glue amount is insufficient, and other dispensing quality problems, the combination = = rubber uneven, adhesion between the inner walls. The two-speaker filter and the lens barrel are strong, and the probability that the lens module will fail when the filter chip is detached will be greatly increased. SUMMARY OF THE INVENTION It is necessary to provide an assembly method and a lens module for a lens module that can ensure assembly quality. a method for assembling a lens module, which comprises: assembling and fixing at least one optical component in a plurality of optical cylinders; loading a component to be assembled into the mirror to be assembled; loading a bonding component Presetting the position in the lens barrel to make the bonding component simultaneously contact the component to be assembled and the inner wall of the lens barrel: heat-melt the bonding component with a heat source, and cure the bonding component The filter is fixed to the inner wall of the lens barrel to form a lens module. A lens module includes a package assembly component, and further includes an optical S component and a thermal fusion bonded component. Also, the inner wall of the lens barrel and the inner wall of the lens barrel are assembled. The assembly method of the lens module is to be assembled, and the component is connected to the material. 11 is added (four) to melt and cure the glued portion to make the miscellaneous The component and the mirror wall are tight = cause: uneven dispensing, insufficient kicking and shadowing chest = hook eight 2 * receiving material to be treated (four) yuan ❹ mirror (four) wall between the two knives "to be assembled 褒 element and the inner wall of the lens barrel The probability of failure between the attached low lens core group due to the falling of the component to be assembled. - The former 2 is placed into a glued component. The process is further effective to ensure the quality of the component to be assembled and the inner wall of the lens barrel = 8 200813613. Compared with the prior art, the material to be assembled in the lens module and the inner wall of the lens barrel are uniformly distributed, which can be prevented. If the dispensing is uneven and the amount of film is insufficient, the phenomenon of the quality of the dispensing will be affected, and the probability of the (4) yuan ^ (4) inner wall H adhesion 'falling money' will be invalid due to the fall of the fourth group. [Embodiment] Embodiments A method for assembling a lens module will be described with reference to the accompanying drawings. 3, the assembling method of the lens module 2 includes a step y. The lens assembly 21 and the spacer ring 22 are sequentially assembled and fixed to the surveying position. Specifically, each lens and the spacer ring 22 in the lens group 21 are subjected to The nozzle of the lens barrel 2G (@not shown) is used in the cartridge 20. In step 200, the filter 23 is loaded into the barrel 2 to be assembled. In this embodiment, the filter 23 is placed at intervals. Above the ring 22. Step 300 'Load the bonding member 24 into a predetermined position in the lens barrel 20 so that the bonding member 24 simultaneously contacts the filter 23 and the wall of the lens barrel. The bonding member 24: the shape and the mirror The shape of the inner wall of the cylinder 2 is matched. In the embodiment, the inner wall of the lens barrel 20 is circular, and the bonding member is formed into a ring shape. In this embodiment, the bonding member 24 is prefabricated into a square ring. In other embodiments, it may be pre-formed into a rectangular shape, a rectangular shape (% shown in FIG. 6), and a circular shape (FIG. 7 200813613). : shows 44) a trapezoidal shape (54 as shown in Fig. 8) and the like. The outer surface of the % t body is equal to or slightly smaller than the lens barrel 2G. The inner diameter of the mounting portion. % ^ The bonding member 24 may be made of a material such as hot melt adhesive. Specifically, the hot melt adhesive may be selected from a polyethylene vinyl acetate hot melt adhesive, a polyacrylic acid adhesive, or a rubber hot melt adhesive. /Step 00, the bonding member 24 is heated and melted by the heat source 1, and the bonding member 24 is cured to fix the filter 23 and the inner wall of the lens barrel 2 (shape), and the conditions are 'a, ' and 2. The heat source can be a device such as a laser device that can cause the bonded component to be heated and smelted. The curing of the bonding member 24 can be achieved by natural cooling, air cooling, and the like. The assembly method is performed after assembling the calender sheet 23, and a bonding member 24' is placed on the filter 23 and heated to the bonding member 24, so that the bonded bonding member 24 filters the filter 23 with The lens barrel 2 () (4) is tightly connected to form a lens module 2 (as shown in FIG. 9). # By this assembly method, it is prevented that the dispensing is not caused by the misalignment (4), and the amount of the transfer is insufficient to affect the occurrence of the dispensing smear phenomenon. [Ensure (4) the member 24 is between the filter 23 and the lens barrel 2 = The hooks are arranged to increase the force of the filter 23 and the inner wall of the lens barrel 2 to reduce the probability that the lens module will fail due to the fall of the filter 23. In this embodiment, an assembly filter is taken as an example, and the above assembly is used to assemble other components in the manufacturing process or (4) other components that can be glued and assembled. In addition, the one-time insertion of a bonding member 24 eliminates the need to position and dispense the dispensing device a plurality of times, which not only speeds up the process but also ensures the bonding quality between the filter 23 and the lens barrel 2 (4). / 200813613 In summary, the invention conforms to the requirements of the issue of the issue of the law. However, the above description is only a preferred embodiment of the present invention, and the circumference of the month is not limited to the above embodiment, and the familiar modification (four) of the skill of the present invention is in accordance with the spirit of the present invention.
