'$ 【Contents of the Invention】 [0004] There is a need to provide a lens module that avoids the bonding quality of the optical lens and the lens module assembly method. Bonded to the mirror _5] - a lens module, which includes _ a barrel and a plurality of 09514729# early posts 1 ^ 3 1 / it 14 f 1013285698-0 1380123 |~ϊοι年〇7^~" ^Day Correction Miscellaneous - An optical component within the barrel, the inner wall of which is an inner tapered surface. [0006] A lens module includes a lens barrel and a plurality of optical elements bonded in the lens barrel, the inner wall of the lens barrel is a plurality of concentric inner tapered surfaces The two inner tapered surfaces are different in diameter to form a holding portion for holding the optical element. [0007] A lens module assembly method 'provides a rotating table in advance, and then performs the following steps: [0008] Fixing the lens barrel on the rotating table, the smaller inner diameter of the lens barrel abuts The rotating table 'the rotating table rotation central axis coincides with the central axis of the lens barrel; [0009] providing a quantitative amount of curable adhesive, dropping it into the lens barrel; [0010] rotating the turn Rotating the table, uniformly applying the curable adhesive to the inner wall of the lens barrel; [0011] sequentially loading the optical component into the lens barrel; [0012] curing the curable adhesive to complete assembly . [0013] The inner wall of the lens barrel of the present invention is an inner tapered surface having a certain slope, and the curable adhesive can be uniformly distributed on the inner wall of the lens barrel, thereby improving the bonding quality of the optical element. Due to the slope, the inner wall of the lens barrel can be glued by means of spin coating, and the dispensing nozzle does not have to be close to the lens barrel to avoid contamination of the lens module. [Embodiment] [0014] First Embodiment [0015] Please refer to FIG. 1 'The lens module 1 of the present embodiment includes a lens barrel 1〇 and 1013285698-0 09514729 production order number Α0101 page 4/total Page 1380123 101.07.26 The shuttle is replacing a plurality of optical elements 2 黏 bonded in the barrel 1 , the inner wall 11 of the barrel being an inner tapered surface. [0016] The lens barrel 10 is formed by plastic injection molding, and of course, other manufacturing methods can be employed. The outer wall of the lens barrel 10 is a cylindrical surface, and a thread is formed thereon so as to be matched with the lens holder. The lens barrel 10 is provided with a focusing ring 12' at one end side of the lens barrel. The focus ring 12 can be formed integrally with the lens barrel 10, or can be formed separately and reassembled at the proximal end side of the lens barrel 1. [0017] Since the inner wall of the lens barrel is an inner tapered surface, if the inner diameter of the one end side of the lens barrel 10 is larger than the inner diameter of the one end of the near image side, the focus ring 12 is disposed on the lens barrel 10 Thereafter, a structure in which the inner diameter of both ends of the lens barrel 1 is smaller than the inner diameter of the middle portion will be formed. In this case, in order to facilitate assembly of the optical element 2, a focusing ring 12 formed separately from the lens barrel 10 is generally used, and the focusing element 12 is assembled into the lens barrel after the optical element 20 is assembled into the lens barrel 10. 1 〇. In the present embodiment, the inner diameter of the one end side of the lens barrel 10 is smaller than the inner diameter of the one end of the near image side, so that the focusing ring 12 formed integrally with the lens barrel 10 is used, so that the assembly of the focusing ring 12 can be reduced. Process. [0018] The optical element 20 of the present embodiment includes a lens, a group 21 and a filter 22 in this order from the object side end. The lens group 21 is composed of two aspherical lenses 23 and 24. Of course, a spherical lens or a larger number of lenses may be employed. The setting of the lens group 21 is not limited to the embodiment. [0019] The side surface 25 of the optical element 20 is also an outer tapered surface, the size of which matches the size of the inner wall 11 of the lens barrel corresponding to the size of the optical element portion. In this way, the bonding area can be increased and the bonding strength can be improved. [0020] Please refer to FIG. 2, the lens module assembly method of the first embodiment of the present invention needs 1013285698-0 09514729# single number Α 0101 1380123, a rotation table 30 is provided in advance on July 26, 2011, and then the following steps are performed: [0021] The lens barrel 10 is fixed to the rotating table 30, and the smaller inner diameter of the lens barrel 1A abuts against the rotating table 3〇, and the rotating center axis of the rotating table 3〇 The central axis of the lens barrel 10 is 〇, coincident; [0022] a quantitative amount of curable adhesive 40 is provided, which is dropped into the lens barrel 1; [0023] rotating the rotary table 30, the The cured adhesive 4 〇 is uniformly applied to the inner wall 11 of the lens barrel; [0024] the optical element 20 is sequentially loaded into the lens barrel 1; [0025] curing the curable adhesive 40 to complete the assembly . Since the inner diameter of the one end side of the lens barrel 10 is smaller than the inner diameter of the one end of the near image side, the near end side of the lens barrel 10 abuts against the rotary table 30. [0027] The rotary table 30 includes a rotating circular table 31 and a cylindrical upper cover 32. One end of the cylindrical upper cover 32 is screwed to the rotating circular table 31, and the other end is internally extended with a stopping portion 33 for blocking the lens barrel 10 to fix the The lens barrel 10. Since the focus ring 12 is provided at one end of the lens barrel 10, the stopper portion 33 can fix the lens barrel 10 by blocking the spacer ring 12.
