New description: [New technical field] The present invention relates to a lens assembly having a plurality of lenses and a lens frame, and a photographing device having the lens assembly thereof, wherein the lens frame has a medium hollow portion and is in a hollow portion Load this multiple lens. [Prior Art] Recently, a car is equipped with a camera. In many cases, such a camera is provided with a display screen on the driver's seat with the spread of the navigation system, and a camera that displays the state of the driver's blind spot is displayed on the screen. & A car-mounted camera that is equipped with a lens located on the most object side to be exposed on the surface of the vehicle body, so strict waterproof performance is required. For this reason, the lens assembly mounted on the vehicle-mounted camera often has a 〇-shaped ring between the outer peripheral surface of the lens on the object side and the inner peripheral surface of the lens frame to prevent water from entering (for example, refer to the patent document). 1). However, in order to obtain higher waterproof performance and dustproof performance, a lens frame in which a hollow portion is formed is often used in the permeable assembly. If a portion = frame is used, the lens is inserted in an orderly manner to the lens sealing lens of the hollow portion 20 = side. However, when the lens frame having the lens frame is used, the lens disposed at the most object side and the lens are subjected to a large factory strength. Therefore, there is a disadvantage that the type 0 is bad and the lens is defective. The problem is that the lens and the 〇-ring are forced to be pressed by the squeezing force from the inside of the lens frame. The 4th giant is that when the lens is pressed together with the 〇-shaped ring by the 3 M361026, the positional accuracy of the lens is not obtained, and the optical performance is lowered. Further, when the assembly is performed by the transmission pressure or the like, even if an assembly failure occurs, it is difficult to remove the lens assembly and the lens and the ◦-shaped ring are not damaged.

According to the photographing apparatus of the present invention described above, by assembling the above-mentioned lens group body, the lens assembly is reduced, and the assembly failure rate of the body is obtained, and a photographing device having a good assembled state is obtained. The lens assembly of the lens assembly that can be attached to the hollow portion of the lens frame can be mounted on the hollow lens of the lens assembly that is temporarily assembled. (4) Decomposition method of the lens assembly, = and the lens assembly having the lens assembly assembled by the above assembly method 褒 5 25 M361026 [Embodiment] The following is an embodiment of the creation of the present invention. Fig. 1 is a view for explaining (4) of Fig. 2 is a cross-sectional view showing a cross section of a lens assembly of Fig. 2, and Fig. 2 is a perspective view showing a lens assembly of the lens assembly. 14 and the lens frame 10, the lens frame 1 has an object side opening and an image side opening, and is formed with a hollow portion 100 in which four lenses n to 14 are inserted to align the optical axis. 10 In FIG. The lenses 11 to 14 are in contact with each other and are placed in the lens frame 10 in alignment with the optical axis. The diameters of the lenses are increased toward the object side to form lenses n to 14. The four lenses 11 to 14 The lens 14 disposed on the most object side constitutes an example of the first lens of the present invention. In the example of Fig. 1, the portion of the image forming side 15 in the outer peripheral surface of the first lens 14 is formed to be formed into a diameter ratio. The 〇-shaped ring 15 disposed on the 侧-shaped ring arranging portion 141 is sandwiched between the %-shaped arranging portion 141 and the hollow portion 1 of the lens frame 1A. The material of the 〇-shaped ring 15 of this example is made of ethylene propylene rubber, ruthenium rubber, etc. Here, as described above, when the lens assembly body of the figure is assembled, it is received by Since there is a considerable pressure in the hollow portion of the towel, there is a problem that it is difficult to attach the first lens 14 and the 〇 ring 15 to the lens frame 1 于是. Therefore, in the present embodiment, the following assembly method is proposed, that is, As shown in Figure 2, the side of the image from the image side opening along the direction of the arrow in the direction of the arrow will be equipped with M 361026 A method of assembling the first lens 14 placed in the 0-ring arrangement portion 141 into the lens assembly of the hollow portion 100 of the lens frame 10. Fig. 3 is a view showing the lens assembly 1 shown in Figs. 1 and 2 Flowchart of the assembled procedure. First, in the first loading step S301, the remaining lenses η to 13 other than the first lens 14 of the four lenses 11 to 14 are loaded in the hollow portion 1 ,, and then, In the Ο-ring arrangement step S302, the 〇-ring 15 is disposed in the 〇-shaped ring arranging portion 141 of the first lens 14, and finally, in the second loading step S3 〇3, air is sucked from the image-side opening while being hollowed out from the hollow portion. The first side lens 14 is placed in a state in which the 〇-shaped ring 15 is disposed in the 环-shaped ring 1 〇 arrangement portion 141. When the air is sucked from the image side opening, the air to be sealed in the hollow portion 10 is sucked from the image side opening to the outside through the minute gap, so that the air is directed from the hollow portion 1 toward the object side. The pressure of the opening is alleviated, and the first lens 14 in the state 15 in which the 〇-shaped ring 已 has been mounted is easily loaded from the object side opening. For this reason, the lens can be accurately placed at a predetermined position in the hollow portion 1 to obtain an effect of obtaining desired optical performance. Further, after the first lens 上述 is mounted as described above, the front end of the lens frame 10 is bent by heat caulking and the lens 14 is held. Alternatively, the assembly of the lens assembly i of Figs. 1 and 2 will be described by simply bonding the portion where the outer peripheral portion of the first through-roller fl4 is in contact with the lens frame 1A. 4 is a diagram explaining the decomposition of the lens assembly body shown in FIG. 2 and the program 7 M361026. In the present embodiment, the following decomposition method is proposed, that is, contrary to the assembly, in the step S401, the edge is opened from the image side. The method of decomposing the lens 14 while blowing in the direction of the arrow in the dotted line shown in FIG. When the lens 14 is taken out while blowing air, the air passes through the minute gap in the hollow portion 100 and flows into the object opening side. Therefore, the lens 14 on the object side can be easily removed. For this reason, the lens taken out can be easily taken out without damaging the lens in the hollow portion 1 of the lens. Further, as long as the lens is fixed by the above-described heat caulking or adhesion, the lens frame 1 can be used for a wide range of lenses not only in the hollow portion 100 but also in the hollow portion 100. After the lens 14 is fixed by heat riveting or bonding, the lens frame 1A to which the lens 14 is fixed is sheared and removed, and the lens can be taken out by the above-described decomposition method. As described above, the method of assembling the lens assembly capable of simply inserting the lens disposed on the most object side with the 〇-ring into the hollow portion of the lens frame, and the lens assembly that can be temporarily assembled can be realized. In the middle part of the lens frame, the lens group is simply taken out without damage, and the lens group split is divided into 20. Finally, an example of the case of this machine is explained. Fig. 5 is a view showing a diagram 兀 > 2. The mirror assembly 1 is suitable for use in a camera mounted on a car 1, a lens assembly camera shown in FIG. 2, and a camera unit shown in Fig. 2; the camera unit shown in Fig. 8 is cut along the optical axis and is shown in the oblique direction. 2, and the drawing 1, the soil plate 210 is adhered and fixed to the camera body frame 2Qn, and the threaded portion is formed in the figure. When the camera unit 2 is assembled, first, the lens assembly 1 of Fig. 2 is screwed into the camera body frame 2, and the lens assembly is bonded and fixed to the camera body frame 20. (4) Water is applied by applying an adhesive to the outer periphery of the lens frame 1 and the front end portion of the camera body frame 20 so that water does not enter the inside of the camera unit from the front end side. Further, the substrate 21 to which the imaging element 21 such as the CCD solid-state imaging device 21 is mounted is bonded to the camera main body frame, and the lens assembly of FIG. 1 'FIG. 2 can be simply assembled to the camera unit 2 in such a simple procedure. in.
