Description

Technical Field

[0002] In a complex optical system, multiple lenses are often required to be combined together to achieve a specific optical effect, and the lens barrel provides an assembly platform for these lenses, so that they can be arranged in a certain order and interval to form the required optical system.

[0003] At present, multiple lenses are usually installed in a lens barrel by manually pinching the edge of the assembled lens ring to install it into the lens barrel. However, due to the limitation of the width of the groove of the lens barrel, human hands cannot be inserted. The lens ring can only be placed above the groove of the lens barrel after observing the position of the groove of the lens barrel with human eyes, and finally the lens ring is loosened to make it automatically fall into the groove of the lens barrel. Such operation causes the lens ring to be unstable before being installed in the groove of the lens barrel, which leads to low assembly efficiency of the lens barrel. At the same time, when placing the rubber ring on each lens ring, it needs to be aligned with the groove of the lens barrel before being inserted. Such operation causes the rubber ring to be installed into the groove of the lens barrel slowly, which affects the assembly efficiency of the lens barrel. Summary of the invention

[0034] A worker first puts the lens sheet 5 into the lens ring 4, then rotates the tightening ring 6, and tightens the lens sheet 5 with the lens ring 4 through the thread, and then puts the assembled lens ring 4 into the conveying component 2, and repeats this process so that the conveying component 2 continuously conveys the assembled lens ring 4. Another worker lifts the threaded disk 75, the octagonal disk 76 and the vertical plate 77, so that the threaded disk 75 is aligned with the thread on the fixed center disk 74 and rotates the threaded disk 75, the octagonal disk 76 and the vertical plate 77, and the threaded disk 75 drives the octagonal disk 76 and the vertical plate 77 along the thread on the fixed center disk 74. 7 moves upward, and after the fixed push ring 910 contacts the octagonal disk 76, the threaded disk 75 is no longer rotated, and then the suction pipe on the external suction pump is connected to the upper ends of the eight connecting pipes 81, and then the conveying assembly 2 and the electric slide rail 71 are started. After the conveying assembly 2 conveys the lens ring 4, the lens sheet 5 and the tightening ring 6 to the bottom of the electric slide rail 71, the conveying assembly 2 is closed, and the electric slide rail 71 drives the electric slider 72 to move and drive the electric push rod 73, the fixed center disk 74, the threaded disk 75, the octagonal disk 76 and the eight vertical plates 77 to move above the lens ring 4, and then the electric push rod 73 is started, and the electric push rod 7 The telescopic rod 3 moves downward, driving the fixed center disk 74, the threaded disk 75, the octagonal disk 76 and the eight vertical plates 77 to move downward together. The octagonal disk 76 moves downward, driving the eight rotating tubes 82 to move downward together. The eight rotating tubes 82 move downward by squeezing the hollow tubes 83 and the suction cups 86 together through the extrusion spring 87. The eight suction cups 86 contact the tightening ring 6. The fixed center disk 74 drives the eight connecting tubes 81, the eight air gun joints 85 and the octagonal disk 76 to continue to drive the eight rotating tubes 82 to move downward. Since the tightening ring 6 is fixed, the eight suction cups 86 and the eight hollow tubes 83 It is also fixed, the extrusion spring 87 is compressed, the eight air gun connectors 2 85 are connected with the air gun connectors 1 84 on the eight hollow tubes 83, and the air gun connector 2 85 on the connecting tube 81 is clamped with the air gun connector 1 84 on the hollow tube 83, so that the connecting tube 81 and the hollow tube 83 are connected, so that the external vacuum pump can suck the tightening ring 6 through the eight connecting tubes 81, the eight hollow tubes 83 and the eight suction cups 86, so that the entire lens ring 4, the lens sheet 5 and the tightening ring 6 can be stably lifted, thereby improving the assembly stability of the lens barrel 3 and the lens ring 4, and then improving the assembly efficiency of the lens barrel 3 and the lens ring.

[0035] The octagonal plate 76 continues to drive the eight vertical plates 77 to move downward, and the eight vertical plates 77 all drive the movable plate 91 and the limit strip 92 to move downward. The downward movement of the eight movable plates 91 makes the fixed plate 94 no longer limit the movable plate 91, thereby making the eight compression springs 93 in the compressed state reset. The eight compression springs 93 reset and push the eight movable plates 91 and the eight clamping blocks 96 to move in the direction close to the lens ring 4. The eight movable plates 91 all push the extension plates 97 to move toward the center direction of the fixed push ring 910. The eight extension plates 97 are in contact with the outer side of the fixed push ring 910, and the eight clamping blocks 96 clamp the lens ring 4. The lens ring 4 is clamped by the eight clamping blocks 96, so that the entire lens ring can be more stably held. 4, the lens piece 5 and the tightening ring 6 are tightly clamped and lifted, so as to further improve the assembly stability of the lens barrel 3 and the lens ring 4, and then further improve the assembly efficiency of the lens barrel 3 and the lens ring, and then the worker controls the electric push rod 73 and the electric slide rail 71 to reset, and the telescopic rod of the electric push rod 73 is reset to drive the fixed center disk 74, the threaded disk 75, the octagonal disk 76, the vertical plate 77, the suction cup 86 and the clamping block 96 to reset upward together, and the suction cup 86 and the clamping block 96 drive the lens ring 4, the lens piece 5 and the tightening ring 6 to reset upward together, and after the telescopic rod of the electric push rod 73 is reset, the electric slide rail 71 drives the electric slider 72 to drive the electric push rod 73 to reset, and after the electric slider 72 drives the electric push rod 73 to reset, the worker starts the electric push rod 73 again. , the telescopic rod of the electric push rod 73 drives the fixed center plate 74, the threaded plate 75, the octagonal plate 76, the vertical plate 77, the suction cup 86 and the clamping block 96 to move downward, the eight vertical plates 77 are inserted into the eight vertical grooves of the lens barrel 3, the eight suction cups 86 and the eight clamping blocks 96 put the lens ring 4, the lens sheet 5 and the tightening ring 6 into the lens barrel 3, and then the worker starts the electric guide ring 98 and turns off the external vacuum pump, the electric guide ring 98 drives the electric sliding ring 99 to rotate, the electric sliding ring 99 drives the fixed push ring 910 to rotate together, the eight protrusions of the fixed push ring 910 synchronously push the eight extension plates 97 and the eight moving plates 91 to reset, the compression spring 93 is compressed again, and the reset of the eight moving plates 91 drives the bottom plate 95 and the clamping block 96 to reset, The eight clamping blocks 96 are reset and no longer clamp the lens ring 4, the external vacuum pump stops pumping air, and the eight suction cups 86 no longer suck the tightening ring 6. Then the worker controls the electric push rod 73 to reset again, and the eight suction cups 86 are disengaged from the tightening ring 6. The fixed center disk 74, the connecting tube 81, the octagonal disk 76, the movable plate 91 and the rotating tube 82 move upward. Under the action of the extrusion spring 87, each hollow tube 83 is reset to drive the air gun connector 1 84 and the fixed plate 94 to reset. The air gun connector 1 84 on the hollow tube 83 is disengaged from the air gun connector 2 85 on the connecting tube 81. The fixed plate 94 is reset to limit the movable plate 91 again. The worker starts the electric guide ring 98 again, and the electric guide ring 98 drives the electric sliding ring 99 to reset back to the initial state.The electric slide rail 71, the electric push rod 73 and the electric guide ring 98 are controlled reciprocatingly in this way, so that the lens ring 4, the lens sheet 5 and the tightening ring 6 conveyed by the conveying assembly 2 can be lifted and loaded into the lens barrel 3 for many times. Finally, the worker takes out the lens barrel 3 loaded with multiple lens rings 4, lens sheets 5 and tightening rings 6 from the groove of the base 1, and then replaces a new lens barrel 3 and puts it into the groove of the base 1.

[0036] Embodiment 2: Based on embodiment 1, Figure 8 and Fig.12 As shown, it also includes a discharge mechanism, which is arranged on the rotating tube 82, and is used to place the rubber ring. The discharge mechanism includes a rotating ring 101, the rotating tube 82 is welded with the rotating ring 101, and the rotating ring 101 is welded with a fixed support plate 102, and a sliding groove is opened on the rotating ring 101, and a magnetic support plate 103 is rotatably connected to the sliding groove of the rotating ring 101, and a magnetic ring 104 is fixedly connected to the sliding groove of the rotating ring 101, and each of the rotating tubes 82 is fixedly connected with an overrunning clutch 1 05. A fixed gear 106 is welded to the outside of each overrunning clutch 105. Eight rotating rods 107 are rotatably connected to the octagonal plate 76. A fixed rack 108 is welded to one side of each extension plate 97 close to the adjacent rotating rod 107. A small gear 109 and a large gear 110 are fixedly connected to each rotating rod 107. The small gear 109 is meshed with the fixed rack 108. The fixed rack 108 is used to push the small gear 109 to rotate. The large gear 110 is meshed with the fixed gear 106.

[0037] At first, due to the opposite magnetic properties of the magnetic support plate 103 and the magnetic ring 104, the magnetic support plate 103 and the magnetic ring 104 are magnetically attracted to each other. Before another worker aligns the threaded disk 75 with the fixed center disk 74, the magnetic support plate 103 on each rotating ring 101 is pushed so that the magnetic support plate 103 on each rotating ring 101 is no longer symmetrical with the fixed support plate 102 on each rotating ring 101. Then, several rubber rings are inserted between the eight rotating rings 101 and the eight vertical plates 77. Then, the magnetic support plate 103 on each rotating ring 101 is pushed back to its original position. Then, each rotating ring 101 is rotated so that the rubber ring at the bottom is attracted by the magnetic support plate on each rotating ring 101. 103, when each movable plate 91 drives the extension plate 97 to move toward the center direction of the fixed push ring 910, it also drives the fixed rack 108 to move, and each fixed rack 108 drives the small gear 109, the rotating rod 107 and the large gear 110 to rotate forward. Through the small gear 109 and the rotating rod 107, the fixed rack 108 moves to drive the large gear 110 to accelerate the rotation, and the large gear 110 drives the fixed gear 106 to rotate. Due to the effect of the overrunning clutch 105, the fixed gear 106 will not drive the rotating tube 82 and the rotating ring 101 to rotate. When each movable plate 91 and each clamping block 96 are reset and no longer clamp the lens ring 4, they are all compressing the spring 9 3, each moving plate 91 drives the extension plate 97 to move toward the center direction of the fixed push ring 910, each extension plate 97 drives the fixed rack 108 to reset, each fixed rack 108 drives the small gear 109, the rotating rod 107 and the large gear 110 to reverse, through the small gear 109 and the rotating rod 107, the large gear 110 reverses and drives the fixed gear 106, the overrunning clutch 105, the rotating tube 82 and the rotating ring 101 to rotate forwardly for one circle, the rotating ring 101 rotates forwardly and drives the fixed support plate 102, the magnetic support plate 103 and the magnetic ring 104 to rotate together, the magnetic support plate 103 no longer supports the rubber ring at the bottom, and the rubber ring at the bottom falls off The fixed support plate 102 rotates forward to hold the second-to-last rubber ring so that the second-to-last rubber ring becomes the new rubber ring at the bottom. The fixed support plate 102 holds the new rubber ring at the bottom. Through such reciprocating operation, a rubber ring can be quickly placed on each lens ring 4, thereby improving the placement efficiency of the rubber rings and further improving the assembly efficiency of the lens barrel 3. When several rubber rings are placed, the worker only needs to rotate the threaded disk 75, take out the threaded disk 75, the octagonal disk 76 and the vertical plate 77, replace them with a new threaded disk 75 with several rubber rings installed, and put the threaded disk 75, the octagonal disk 76 and the vertical plate 77.
