Glass lens manufacturing processes are complex, including cutting, grinding and other processes. Plastic lenses are generally manufactured using precision injection molding methods. The molds required for their manufacture are costly. β [Invention] In view of the above, it is necessary to provide a lens module which is easy to manufacture and has a low cost. — A lens module comprising a lens barrel and at least one lens. The diameter of the mirror is larger than the inner diameter of the barrel. The lens is bent in the direction of the center axis of the lens barrel and fixed in the lens barrel, and the center of the lens is located on the central axis of the lens barrel. A camera module comprising a substrate, a lens holder fixed to the substrate, an image sensing chip fixed to the substrate and located in the lens holder, and fixed to the lens holder The lens module. The lens includes a lens barrel and at least a lens. The diameter of the lens is larger than the inner diameter of the barrel. The lens is bent in the central axis direction of the lens barrel and fixed in the lens barrel, and the center of the lens is located at a central axis of the lens barrel: compared with the prior art, the lens module and the application thereof In contrast, the lens is bent into a lens having a predetermined curvature of $6 201013246 by bending a lens having a diameter larger than the inner diameter of the lens barrel along the center of the lens barrel into the lens barrel, thereby forming a simple structure. A lens module that is easy to manufacture and low in cost. [Embodiment] Hereinafter, the following preferred embodiments will be described in detail with reference to the accompanying drawings. Referring to FIG. 1 to FIG. 3, a lens module 1 according to a first embodiment of the present invention includes a lens barrel 1 and at least one lens. In the present embodiment, the lens module 1 includes three lenses 12, 14, 16.镜 The lens barrel is a hollow cylinder having an end portion 101 and an inner wall 102. A circular through hole 1〇3 is defined in the end portion 101 for allowing external light to enter the lens barrel 1 through the through hole 1〇3. The center of the through hole 1〇3 is located on the central axis of the lens barrel 1〇. The inner wall 102 of the lens barrel 1 is provided with three recesses 104 which are spaced around the inner wall 1 and are spaced apart from each other. The two lenses 12, 14, 16 are both light transmissive and elastically bendable dome lenses having diameters greater than the inner diameter of the barrel 1 . The radii of the three lenses 12, 14, 16 can be different. Preferably, the three lenses 12, 14, 16 are made of a light transmissive plastic having better elasticity. After the three lenses 12, 14, 16 are bent in the central axis direction of the lens barrel 1Q, the edges thereof are respectively engaged with the three grooves 104 of the inner wall 102 of the lens barrel 1 to be fixed. Inside the barrel. The center of the three lenses 12, 14, 16 is located on the central axis of the barrel. Since the diameters of the three lenses 12, 14, 16 are larger than the inner diameter of the barrel 1 , the three lenses 12 , 14 , 16 are bent into a lens having a predetermined curvature in the barrel 10 for use. Change the path of the incident light by 7 201013246. When the lens module 1 is assembled, the lens 12 can be bent into a shape by a clamping device (not shown), and the convex surface of the lens 12 is adsorbed by a suction device (not shown), so that the lens The lens maintains a curved shape, and then the lens 12 is placed in the lens barrel through the suction device to the corresponding groove 104, and the suction device is taken out to engage the lens 12 in the groove under the elasticity of itself. Within 1〇4. The other two lenses 14, 16 are then assembled in sequence. Referring to FIG. 4, the lens module 3 according to the second embodiment of the present invention is different from the lens module provided by the first embodiment in that the lens barrel 30 includes a first portion 3〇. 2 and a second portion 3〇4 corresponding to the first portion 302. Preferably, the first portion 3〇2 and the first 4 are 304 are symmetrical with respect to a central axis of the barrel 3〇. The first knife 302 is a semicircular bay including an inner wall 3021 and an end portion 3022. The inner wall 3021 is provided with three sets of engaging structures 3〇23 spaced apart from each other and surrounding the inner wall ❹3021 for respectively fixing the three lenses U, 34, 36. The end portion 3〇22 is provided with a semi-circular hole 3〇24 for allowing external light to enter the lens barrel 30. The center of the semicircular hole 3024 is located on the central axis of the barrel 30. The second portion is torn and the first portion 302 abuts and is fixedly coupled to form the lens barrel 30. The second portion 3〇4 and the first portion 3〇2 may be joined together by gluing. When assembling the lens module 3, the one lens 32, 34, 36 may be first bent into a certain shape by a clamping device (not shown), and the first portion 302 of the lens barrel 30 is engaged with 201013246. The corresponding snap-fit structure 3023 is then 'fixed the second portion 304 of the lens barrel 30 to the first portion 302' and the retaining means is removed to secure the lenses 32, 34, 36 Inside the barrel 30. It can be understood that the number of the lenses included in the lens module depends on the optical design requirements. The number of the grooves or the engaging structures in the lens barrel also changes accordingly, and is not limited to the embodiment of the present invention. number. FIG. 5 shows a camera module 5 for applying the lens module 1. The lens module 1 includes a lens module 1, a lens holder 52, a substrate 54 and an image sensing chip 56. The lens holder 52 is fixed to the lens holder 52. The substrate 54 is formed with an accommodating space 58.
