Field of the Invention The present invention relates to an exposure apparatus, and more particularly to an exposure apparatus that can be used in a lens module assembly process. [Prior Art] With the development of optical imaging technology, lens modules are widely used in various imaging devices such as digital cameras and video cameras (see Capturing images with digital still cameras, Micro, IEEE Volume: 18, O issue: 6, Nov.-Dec.l998 Page(s): 14-19), and electronic devices such as mobile phones and notebook computers integrated with lens modules have been favored by many consumers. The lens module usually includes components such as a lens holder, a lens barrel, a lens group, a spacer ring, and a filter. The lens group, the spacer ring and the filter are sequentially fixed in the lens barrel along the optical axis direction of the lens module. The outer wall of the lens barrel and the inner wall of the lens holder are usually provided with matching threads, and the lens barrel is screwed into the lens holder to be fixed. During the assembly of the lens module, the optical components such as the lens group and the filter are assembled into the lens barrel and fixed. Ultraviolet (Ultra Violet (UV) glue is usually applied to the optical component, and the optical device is used to expose the optical device. The UV glue on the component is cured. In the prior art UV glue curing process, the exposure apparatus 2 (please refer to Fig. 1) includes a UV light source 21, a straight conveyor belt 22 having a straight line, and a carrier tray 23. When exposing the component coated with UV glue in the lens barrel, the operator places the carrier 23 carrying a plurality of lens barrels on one end of the linear conveyor belt 22, and turns on the UV light source 21' linear conveyor belt 5 200928597 ^ 22 The carrier tray 23 is transported from one side of the UV light source 21 to the other side of the UV light source 21, and the other operator removes the carrier tray 23 from the other end of the linear conveyor belt 22, during which the lens barrel is in the UV When under the light source 21, the UV light source 21 cures the UV glue on the optical elements within the lens barrel. However, when the UV adhesive on the optical component is cured by the exposure device of the prior art, some UV light leaks, and the operator may have the corresponding protective measures but may be injured by the UV light and require more operators. . SUMMARY OF THE INVENTION ® In view of the above, it is necessary to provide an exposure apparatus that protects an operator from UV light and requires less operator. An exposure device comprising an ultraviolet light source, a conveyor belt under the ultraviolet light source, the conveyor belt is a curved conveyor belt with a closed curve, and the curved conveyor belt can guide the exposed object along the conveying route delivery. Compared with the prior art, the exposure apparatus provided by the embodiment of the present invention includes a q-curve type conveyor belt. The curved conveyor belt keeps the operator away from UV light sources and the exposure device requires fewer operators. [Embodiment] The present invention will be further described in detail below with reference to the drawings. Please refer to FIG. 2, which is an exposure apparatus 3 according to an embodiment of the present invention. The exposure apparatus 3 includes a UV light source 31, a frame 32, an anti-UV cloth 33 disposed on the frame 32, a curvilinear transport belt 34 having a curved path, and a plurality of carrier trays 35 carrying the exposed objects. The UV light source 31 emits a UV beam that exposes the exposed object. 6 200928597 The frame 32 is mounted on a support (not shown) supporting the exposure device 3. The frame 32 can be made of metal, plastic, rubber, wood, etc., which is a rectangular rectangular frame. It can be understood that the frame 32 can also have other shapes, such as a hexagonal frame, a ring frame, etc., and is not limited to the embodiment, as long as the area where the uv light may be exposed is in the frame 32. The anti-UV cloth 33 is erected behind the frame 32, and can completely cover the area where the uv light may leak, thereby protecting the employee from the UV light damage. In the yoke example, the anti-UV cloth 33 is adhered to the frame 32 by adhesion. It can be understood that the anti-UV cloth 33 can be erected on the frame by other means, for example, the clip is clamped on the frame 32, and is not limited to the embodiment, as long as the anti-uvw% is mounted on the frame 32. The curved conveyor belt 34 is used to carry and transport the carrier tray 35. The curved conveyor belt 34 can be made of materials such as metal, rubber, plastic, and the like. In the present embodiment, the curved conveyor belt 34 is a curved conveyor belt made of stainless steel wire and having a rectangular curve with a rounded corner. It can be understood that the curved type of the belt can also be other shapes, such as an ellipse, and is not limited to the embodiment, as long as it is convenient to transmit. The carrier tray 35 is provided with one or more receiving slots 351 for receiving the exposed objects. The carrier tray 35 can be made of materials such as metal, plastic, wood, and the like. In this embodiment, the carrier tray 35 is a circular carrier disk made of aluminum and has four receiving slots 351. The four accommodating grooves 351 are distributed on the carrier tray 35 in a square shape. It can be understood that the carrier tray can also have other shapes, such as a square shape, an elliptical shape and the like, and is not limited to the embodiment, as long as the carrier tray 35 does not slip during the transmission 200928597. It is also understood that the distribution of the accommodating grooves 351 is not limited to the embodiment, and the accommodating grooves 351 may be regularly distributed or irregularly distributed. When exposing the optical component coated with the UV glue in the lens barrel, the lens barrel is placed in the accommodating groove 351 so that the component coated with the UV glue in the lens barrel is under the UV light source, as opposed to the UV light source 31. . The operator at A places the carrier tray 35 with the lens barrel on the curved conveyor belt 34, turns on the UV light source 31, and the curved conveyor belt 34 carries the carrier tray 35 from A through the UV resistance at B. The cloth 33, the UV-resistant light source 33, and the anti-UV cloth 33 at C are transported one turn and then transported to A, and the operator removes the carrier tray 35 from A. During the transport, the lens barrel is under the UV light source 31. The UV light source 31 cures the UV glue on the optical components in the lens barrel. During the operation, since the operator is away from the UV light source 31 and protected by the ultraviolet protection cloth 33, the operator can be protected from the UV light even if there is no protection measure, and only one operator can complete the related operation. 0 thus reducing the number of operators. It will be appreciated that the operator can continuously take the carrier tray 35 onto the curved conveyor belt 34 and place the other carrier tray 35 thereon. It can be understood that the number of the frames 32 can also be plural, and the number of the anti-UV cloths 33 can also be a plurality of blocks, and is not limited to the embodiment, as long as the UV light can be blocked to prevent the UV light from leaking. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Any equivalent modifications or variations made by those who are familiar with the present invention in the spirit of the present invention shall be covered by the following patents.
