[0002] AR (Augmented Reality) and VR (Virtual Reality) are two different immersive technologies with a wide range of uses, differing primarily in how they alter or enhance our perception of the real world.

[0003] AR / VR devices all require lenses to realize their functions when in use. The lenses contain multiple groups of different lenses to achieve effects such as light transmission and refraction. During assembly, most lens components are moved by suction cups adsorbing the lenses. After the transfer is completed, the suction cups will move in the air and come into contact with and adsorb dust in the air, affecting the subsequent adsorption effect.

[0010] Further technical solution: A third material taking cylinder coaxially arranged with the second material taking cylinder is fixedly installed on one end of the vertical rod away from the protection box, and the third material taking cylinder is slidably connected to the second material taking cylinder.

[0011] Further technical solution: two groups of air collecting cylinders are fixedly installed on the mounting ring, and a piston plate is slidably installed in the air collecting cylinder.

[0015] 2. A closed space is formed by placing a plate, a third material barrel, a second material barrel, a mounting ring and a second baffle. As the second material barrel moves downward, the piston plate remains in position and the gas collecting barrel moves downward, so that the gas in the closed space can be drawn into the gas collecting barrel, thereby reducing the air and dust content in the closed space, thereby further reducing the outside air from entering the protective box and the space enclosed by the first material barrel and the second material barrel, and further ensuring the cleanliness of the gas in the protective box.

[0016] 3. After the second material collection barrel quickly rises to the set position, the vertical rod contacts the support rod, and continues to push the vertical rod downward under the restriction of the support rod, so that the gas in the gas collecting barrel is quickly squeezed out, so that the air can be quickly ejected from the blowing holes on the first cleaning ring and the second cleaning ring. The air blown out by the first cleaning ring is used to sweep the lower surface of the second baffle plate, reducing the dust content on the second baffle plate, and further reducing the amount of dust entering the protective box when the second baffle plate is opened. The air blown out by the second cleaning ring is used to sweep the lower surface of the third material collection barrel, improving the sealing performance when the third material collection barrel contacts the placement plate, further reducing the probability of dust entering the enclosed space, and further improving the cleanliness level in the protective box.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] like Figures 1-9As shown, an AR / VR device lens assembly assembly device provided by the present invention includes a base 1, a protective box 10 is fixedly installed on the base 1, two groups of movable plates 18 are slidably installed in the protective box 10, and a servo module 19 is provided in the protective box 10 to drive the two groups of movable plates 18 to move synchronously, a third telescopic member 16 is fixedly installed on the movable plate 18, a suction cup 17 is fixedly installed on the output end of the third telescopic member 16, the suction cup 17 is connected to the negative pressure device body 20 fixedly installed on the movable plate 18, both ends of the protective box 10 are fixedly connected to the first material taking barrel 22, the middle part of the protective box 10 is connected to the connecting barrel 11, two groups of conveyor belts 2 are provided on the base 1, a plurality of groups of placement plates 3 are fixedly installed on the conveyor belt 2, and the placement plates 3 are fixedly installed. A positioning plate 5 is provided, and a plurality of groups of telescopic tubes 4 distributed in a circular array around the center of the placing plate 3 are fixedly installed on the placing plate 3. The positioning plate 5 is fixedly installed at one end of the telescopic tube 4 and a spring is provided in the telescopic tube 4. A fixing screw is provided on the telescopic tube 4. The projection of the first material taking barrel 22 to the base 1 is located on the corresponding conveyor belt 2. A first telescopic member 6 is fixedly installed on the base 1, and a support plate 7 is fixedly installed on the output end of the first telescopic member 6. A splint 8 is provided on the support plate 7, and an adjusting screw 9 is rotatably installed on the support plate 7. The adjusting screw 9 is threadedly connected to the two groups of splints 8 and drives the two groups of splints 8 to move synchronously in opposite directions. The surfaces of the splints 8 close to each other are provided with V-shaped grooves, and the axis of the connecting tube 11 is located in the symmetry plane of the splint 8 itself.

[0030] Among them, a coaxially arranged second material taking cylinder 23 is slidably installed in the first material taking cylinder 22 and a fourth telescopic part 21 that drives the second material taking cylinder 23 to move is fixedly installed on the protective box 10, and a mounting ring 24 is fixedly installed on the end of the second material taking cylinder 23 away from the protective box 10, and two groups of second baffles 25 are rotatably installed on the mounting ring 24, and two groups of vertical rods 26 are slidably installed on the mounting ring 24, the vertical rods 26 pass through the mounting ring 24 and a second pull wire 27 is fixedly connected to the vertical rod 26, and the end of the second pull wire 27 away from the vertical rod 26 is connected to the second baffle 25 near its rotation axis.

[0031] In actual application of this embodiment, lenses of different models to be installed are placed on different conveyor belts 2 for transportation, and the lenses are placed on the placement plate 3. The position of the positioning plate 5 is adjusted according to the size of the lens and fixed by fixing screws, so that after the lens is placed on the placement plate 3, it can contact multiple positioning plates 5 at the same time to achieve the positioning of the lens, and the lens barrel is placed on the support plate 7. The two groups of clamps 8 are driven to move synchronously by adjusting the screw 9 so that the clamps 8 are in contact with the lens barrel. The lens barrel is positioned and fixed by the V-shaped structure on the clamp 8 so that the axis of the lens barrel and the connecting tube 11 coincide. Then the first telescopic member 6 drives the support plate 7 to move upward so that the lens barrel is in contact with the connecting tube 11.

[0032] When the second material picking cylinder 23 is reset, the second baffle plate 25 is reset under the action of gravity to block the bottom of the second material picking cylinder 23 again.

[0033] The movable plate 18 carrying the lens is moved to the top of the connecting tube 11, and then the third telescopic member 16 drives the lens to move downward into the set position in the lens barrel, releases the fixation of the lens by the suction cup 17, and retracts the third telescopic member 16 to reset. At this time, another set of movable plates 18 is located just above the first material taking barrel 22 and can take out the lens. Repeat the above steps, and another set of taken lenses is moved to the top of the connecting tube 11 for installation, realizing the simultaneous installation and loading. After the lens and the lens barrel are assembled, the support plate 7 is moved downward, the lens barrel is removed and replaced, and the assembly operation can be continued. Through the setting of the second baffle plate 25, the lower end of the second material taking barrel 23 is opened when taking the lens, and is closed again after the lens is taken. Subsequent transportation, installation and unloaded movement of the suction cup 17 all move in the protective box 10. Through the setting of the first material taking barrel 22, the second material taking barrel 23, the connecting barrel 11 and the second baffle plate 25, the suction cup 17 moves in a closed space, thereby reducing the probability of outside air entering the protective box 10, and further reducing the probability of dust adhering to the suction cup 17, ensuring the cleanliness of the suction cup 17, and avoiding affecting subsequent transportation and the lens.

[0034] In an example of the present embodiment, the first telescopic member 6, the third telescopic member 16, and the fourth telescopic member 21 are respectively the first, third, and fourth electric telescopic rods. Of course, they can also be other components that can actively change the length, such as hydraulic cylinders. The support plate 7 is driven up and down by the first electric telescopic rod, the suction cup 17 is driven up and down by the third electric telescopic rod, and the second material collection barrel 23 is driven up and down by the fourth electric telescopic rod.

[0035] like Figure 3 、 Figure 7As shown, an AR / VR device lens assembly device provided by the present invention is provided. Two groups of first baffles 12 are rotatably installed at one end of the connecting tube 11 away from the protective box 10. A second telescopic member 13 located in the connecting tube 11 is fixedly installed on the surface of the protective box 10. A lifting ring 14 is fixedly installed at the output end of the second telescopic member 13. A first pull wire 15 is fixedly connected to the position of the lifting ring 14 corresponding to the installation of the first baffle 12. The end of the first pull wire 15 away from the lifting ring 14 is fixedly connected to the corresponding first baffle 12. The position where the first pull wire 15 is connected to the first baffle 12 is close to the rotation axis of the first baffle 12. When the first baffle 12 is horizontal, the lower end of the connecting tube 11 is closed.

[0036] When this embodiment is actually used, the second telescopic member 13 drives the lifting ring 14 to move upward, and the lifting ring 14 drives the first baffle 12 to rotate to a nearly vertical state through the first pull wire 15, thereby releasing the blockage of the lower end of the connecting tube 11. When the lens barrel leaves the connecting tube 11 or is not in use, the lifting ring 14 is reset, and the first baffle 12 is reset under the action of gravity to close the bottom of the connecting tube 11 again, so that the lower end of the connecting tube 11 can be opened and closed according to assembly needs, reducing the time that the protective box 10 is connected to the outside air, further reducing the dust carried by the outside air into the protective box 10, further improving the cleanliness level inside the protective box 10, and ensuring the cleanliness level of the suction cup 17.

[0037] In one embodiment of the present invention, the second telescopic member 13 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the first baffle 12 is driven to open by the second electric telescopic rod.

[0038] like Figures 1-9 As shown, an AR / VR device lens assembly device provided by the present invention, a third material taking barrel 28 coaxially arranged with the second material taking barrel 23 is fixedly installed on one end of the vertical rod 26 away from the protective box 10, and the third material taking barrel 28 is slidably connected to the second material taking barrel 23.

[0039] Specifically, two groups of air collecting cylinders 29 are fixedly installed on the mounting ring 24, and a piston plate 31 is slidably installed in the air collecting cylinder 29. The piston plate 31 is fixedly connected to the corresponding vertical rod 26 through a connecting frame 30. The air collecting cylinder 29 is connected to an air intake pipe 32 and an air outlet pipe 33. Both the air intake pipe 32 and the air outlet pipe 33 are provided with a one-way valve. The air intake pipe 32 is located on the mounting ring 24 and extends into the third material taking cylinder 28. A support rod 36 used in conjunction with the vertical rod 26 is fixedly installed in the first material taking cylinder 22, and an elastic member 37 is fixedly installed on the vertical rod 26. The elastic member 37 is fixedly connected to the mounting ring 24.

[0040] Specifically, the air outlet pipe 33 is connected to a first cleaning ring 34 fixedly mounted on the mounting ring 24 and a second cleaning ring 35 slidably mounted on the third material taking barrel 28. The first cleaning ring 34 is provided with multiple groups of blowing holes facing the second baffle plate 25, and the second cleaning ring 35 is also provided with multiple groups of blowing holes facing the second baffle plate 25. In the initial state, the second cleaning ring 35 is located on the lower side of the third material taking barrel 28 and cleans the lower end surface of the third material taking barrel 28.

[0041] When this embodiment is actually used, when the second material barrel 23 moves toward the placement plate 3, the third material barrel 28 first contacts the placement plate 3. At this time, the placement plate 3, the third material barrel 28, the second material barrel 23, the mounting ring 24 and the second baffle plate 25 form a closed space. As the second material barrel 23 moves downward, the piston plate 31 remains in position and the gas collecting barrel 29 moves downward, so that the gas in the closed space can be drawn into the gas collecting barrel 29, thereby reducing the air and dust content in the closed space, thereby further reducing the outside air from entering the protective box 10 and the space surrounded by the first material barrel 22 and the second material barrel 23, further ensuring the cleanliness of the gas in the protective box 10. As the second material barrel 23 continues to descend, the second pull wire 27 will pull the second baffle plate 25 to open, and the second material barrel 23 stops moving after descending to the set position. At this time, the elastic member 37 is in a stretched state.

[0042] Before the third material taking barrel 28 contacts the placing plate 3, the second cleaning ring 35 first contacts the placing plate 3. Under the push of the placing plate 3, the second cleaning ring 35 moves to the same height as the lower end of the third material taking barrel 28. When the lens is taken out, the second material taking barrel 23 moves upward. Under the action of the elastic member 37, the vertical rod 26 and the third material taking barrel 28 remain unchanged. The second material taking barrel 23 drives the mounting ring 24 to move upward slowly. At this time, part of the gas in the gas collecting barrel 29 is squeezed out and the second baffle plate 25 is slowly closed. The squeezed out gas is filtered through the filter on the air outlet pipe 33 and then transported to the first cleaning ring 34 and the second cleaning ring 35. When the second baffle plate 25 is completely closed, due to the presence of the one-way valve, the force applied by the elastic member 37 to the piston plate 31 is not enough to push the piston plate 31 to continue moving. At this time, the second material taking barrel 23 rises rapidly, causing the third material taking barrel 28 to leave the placing plate 3 At the same time, the second cleaning ring 35 moves to the bottom of the third material collection barrel 28. After the second material collection barrel 23 quickly rises to the set position, the vertical rod 26 contacts the support rod 36 and continues to push the vertical rod 26 downward under the restriction of the support rod 36, thereby quickly squeezing out the gas in the gas collecting barrel 29, so that the air can quickly be ejected from the blowing holes on the first cleaning ring 34 and the second cleaning ring 35. The air blown out by the first cleaning ring 34 blows the lower surface of the second baffle plate 25, reducing the dust content on the second baffle plate 25, and further reducing the amount of dust entering the protective box 10 when the second baffle plate 25 is opened. The air blown out by the second cleaning ring 35 blows the lower surface of the third material collection barrel 28, improving the sealing of the third material collection barrel 28 when it contacts the placement plate 3, further reducing the probability of dust entering the enclosed space, and further improving the cleanliness level in the protective box 10.

[0043] In one embodiment of the present invention, the elastic member 37 is a spring, and of course it can also be other elastic components such as an elastic line, and the spring stretches to apply a resetting pulling force to the vertical rod 26.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
