When the lens is placed in the accommodating cavity, the lens is sometimes caused by the limitation of the size of the lens and the accommodating cavity and the manual and mechanical errors. When tilting to the side with respect to the accommodating cavity, when the punch is punched, the lens is damaged due to uneven force on the lens, thereby reducing the yield of the product.

Preferably, the first bearing bowl 112 is integrally formed with the base 10. The second bearing bowl 113 is fixedly disposed on one side of the lens holder 12 with respect to the base 1 . Preferably, the second bearing bowl 113 is integrally formed with the lens holder 12. The shape of the first bearing sleeve 112' 113 and the rolling bearing U1 may be curved and tapered. In the embodiment, the first 'second bearing bowl 11 2, 11 3 and the rolling bearing 111 The shape of the joint is curved. The diameter of the rolling bearing 111 is greater than the sum of the maximum arch heights of the first and second bearing bowls 11 2, 113 so that the base 1 〇 and the lens holder 096127527 Form No. Α 0101 Page 6 / Total 16 Page 1003066036 -0 1342963 There is a gap 15 between the correction replacement pages 12 on February 25, 100, to facilitate any movement when the lens holder 12 is stressed. [0013] The elastic member 13 is disposed in the gap 15 between the base 10 and the lens holder 2" Preferably, the elastic member 13 is a plastic elastic ring. The two end faces of the elastic member 13 are in contact with the susceptor 1 〇 and the lens holder 12, respectively. The elastic member 13 is used to restore the lens holder 12 to its original shape after the force received by the lens holder 12 has disappeared, so as to facilitate the next assembly. At the same time, the resilient element 13 can also be used to cushion the momentum from the punch 14. [0014] The punch 14 is preferably a cylindrical shape, it being understood that other shapes, such as square or rectangular or hollow cylinders, may also be used. Preferably, the punch 14 is disposed at one end of the first accommodating cavity 121 and is disposed on the machine table (not shown) at a distance from the first accommodating cavity 121, and can be controlled by the machine. Down, it can move along the axial direction of the punch 14. The punch 14 is used to punch a lens housed in the lens holder 12. [0015] As shown in FIG. 4, a lens assembly system 200 is provided in accordance with a second embodiment of the present invention. The lens assembly system 2 includes a base 2〇, a universal joint 21 connected to the base 2〇, a lens holder 22 connected to the base 2 through the universal joint 21, and a setting The elastic member 23 and the punch 24 between the base 2 and the lens holder 22. [0016] The lens assembly system 200 differs from the lens assembly system 1 of the first embodiment in the structure of the universal joint 21. The universal joint 21 includes a bearing projection 211 and a bearing bowl 212 for receiving the bearing projection 211. One end of the bearing protrusion 211 can be fixedly connected to the base 2 〇 or the lens holder 22, in the embodiment, the bearing protrusion 096127527 Form No. A0101 Page 7 / Total 16 Page 1003066036-0 [0017] 1342963 The correction replacement page 211 of February 25, 100 is fixedly coupled to the lens holder 22, and the bearing bowl 212 is fixedly coupled to the base 20. Similarly, when the bearing projection 211 is coupled to the base 20, the bearing bowl 212 is fixedly coupled to the lens holder 22. Preferably, the bearing projection 211 of the universal joint 21 is integrally formed with the lens holder 22, and the bearing bowl 212 is integrally formed with the base 20. It is of course conceivable that the bearing lug 211 of the universal joint 21 can also be integrally formed with the base 20, while the bearing bowl 212 is integrally formed with the lens holder 22. The gimbal 21 is coaxially disposed with the accommodating cavity 221 of the bearing socket 22, as in the first embodiment. [0018] As shown in FIG. 5, it is a schematic diagram of a state in which the lens assembly system 100 of the first embodiment is used. Here, v毽 is taken as an example to illustrate that when the assembled lens 32 is not aligned with the axis and the axis of the accommodating cavity 121............... That is, the position of the lens 12 is changed. Of course, it can be understood that the position of the lens holder 22 is the same as that of the lens _: 12 when assembled by the cane whip system 200. As can be seen from Fig. 5, when the mirror/32 帝 容 腔 ι ι , , ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι ι The inclination of the slit 32 is reversed so that the axis of the punch 14 and the lens 32 are aligned, so that the lens 32 is evenly stressed, so that the lens 32 is not easily damaged. [0019] It will be appreciated that in order to ensure that each lens coincides with the axis of the housing of the lens holder, each lens, including the first lens, is stamped once with a punch. [0020] In addition, it should be noted that after all the lenses are assembled, the assembled lens group is sucked from the accommodating chamber by a jig such as a suction nozzle to perform the next assembly process. 096127527 Form No. 1010101 Page 8 of 16 1003066036-0 1342963 February 25, 2005 Nuclear Replacement Page [0021] The above lens assembly system when placing a lens into the accommodating cavity of the lens holder, due to The size limitation and the manual and mechanical errors make the lens tilt relative to the accommodating chamber. When the punch is punched, the lens holder is also tilted under the cooperation of the universal joint to ensure that the axis of the lens and the punch are consistent, so that the force of the lens is kept uniform, the damage rate of the lens is reduced, and the product is improved. Yield. [0022] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make equivalent modifications or changes in accordance with the spirit of the present invention. It should be covered by the following patent application.
