Step 2: Provide to be grouped The lens module 20 includes a lens barrel 21 and a lens group 22; [0037] Step 3: The lens group 22 to be assembled is placed in the second barrel 122 of the lens assembly jig 12, as shown in FIG. 3. [0038] Step 4: Acquire the lens barrel 21 to be assembled, and place the lens barrel 21 into the first cylinder 121 of the lens assembly jig 12 and place it on the platform 1 222, as shown in Fig. 4. [0039] Step 5: The push rod 14 is used to abut the end of the first cylinder 121 facing the push rod 14, and the push rod 14 is moved toward the base 11 until the lens group 22 is completely placed into the lens barrel 21, as shown in the figure. [0040] Thus, the assembly of the entire lens module 20 is completed. If it is necessary to assemble a plurality of lens modules, steps 2 to 5 can be repeated. [0041] It can be understood that the lens group system 100 can Assembly of each optical component, such as a plurality of lenses, spacer rings, and filters, wherein the diameter of the push rod 14 is less than or equal to the inner diameter of the second cylinder 122 so that the push rod 14 # can extend into the second In the cylinder 122, the mounted optical elements are pressed together, and finally, the lens barrel 21 is loaded into the first step as in the above steps 2 to 5. In a cylinder 121, the assembled lens group is then inserted into the lens barrel 21, thereby completing the assembly of the entire lens module 20. [0042] In order to match the lens barrel 21 having different axial lengths, it is conceivable that The first cylinder 121 of the lens assembly jig is threaded or bonded together in the second cylinder 122, so that the depth of the first cylinder 121 can be adjusted according to the axial length of the lens barrel 21, which has been strengthened.
