Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-8 The figure shows an intelligent suspension conveying device for the production, assembly and lifting of optical device accessories, including a track 1 and a working platform 14. The track 1 is fixedly installed above the working platform 14. There are two groups of tracks 1. A support plate 3 is provided between the track 1 and the working platform 14. The support plate 3 is connected to the track 1 through a moving mechanism. A loading mechanism is provided above the support plate 3. A suction cup 4 is fixedly installed on the side of the support plate 3 close to the working platform 14. A storage trough 15 is slidably installed above the working platform 14 through an elastic structure. The storage trough 15 opens upward, and a smear member 22 is provided inside the storage trough 15. The smear member 22 is connected to the storage trough 15 through a flipping mechanism. A push block 18 is fixedly installed on one end of the support plate 3 close to the storage trough 15, and a limit plate 17 is slidably installed on the end of the storage trough 15 away from the support plate 3. A lifting mechanism is provided below the limit plate 17.

[0030] The moving mechanism includes a moving trolley 2, which is slidably installed inside the track 1. A plate 5 is fixedly installed under the moving trolley 2. A rotating shaft 6 is fixedly installed at both ends of the support plate 3. The rotating shaft 6 is rotatably connected to the plate 5, and a driving structure is provided at the end of the rotating shaft 6 away from the support plate 3.

[0031] The driving structure includes a number one gear 7 and a rack 8. The number one gear 7 is fixedly sleeved on the outer surface of the rotating shaft 6. The rack 8 is fixedly installed above the working platform 14. The number one gear 7 and the rack 8 are meshed.

[0032] After the trolley 2 is lifted up, the support plate 3 is lifted up and the support plate 3 is lifted up, and the trolley 2 is lifted up and the support plate 3 is lifted up, and the support plate 3 is lifted up and the support plate 3 is lifted up.

[0033] The loading mechanism includes a blanking piece 9, which is arranged above the support plate 3. A horizontal plate 10 is fixedly installed above the blanking piece 9. The horizontal plate 10 is slidably connected to the plate 5. The horizontal plate 10 is connected to the moving trolley 2 through an elastic piece 13. A vertical plate 11 is fixedly installed above the horizontal plate 10. The vertical plate 11 extends to the top of the track 1. An inclined plate 12 is fixedly installed above the track 1. The end face of the inclined plate 12 below the vertical plate 11 is inclined, and the inclined plate 12 is in contact with the vertical plate 11.

[0034] Specifically, when the support plate 3 moves to the bottom of the inclined plate 12, the vertical plate 11 contacts the inclined plate 12, and the end face of the side of the inclined plate 12 close to the vertical plate 11 is inclined. Therefore, the inclined plate 12 pushes the horizontal plate 10 downward through the vertical plate 11, and the horizontal plate 10 drives the blanking part 9 to move synchronously. At this time, the elastic part 13 is deformed by the force, and the blanking part 9 places the glass slide inside the groove body on the optical device accessory. It should be noted that the glass slide is adhered to the bottom of the blanking part 9 so that the glass slide can move synchronously with the blanking part 9. The viscosity of the glue inside the groove body is greater than the viscosity between the glass slide and the blanking part 9. The glass slide can also be clamped under the blanking part 9 by a clamp. People in this field can select a suitable clamp according to actual needs during actual use. The clamp is a prior art.

[0035] The elastic structure includes a groove 19, which is opened inside the working platform 14. A rod 20 is fixedly installed inside the groove 19. The rod 20 is horizontally arranged. The rod 20 is slidingly connected to the storage trough 15. The outer surface of the rod 20 is slidingly sleeved with a spring No. 21, and the spring No. 1 21 is fixedly connected to the storage trough 15.

[0036] Specifically, when the support plate 3 drives the storage trough 15 to move synchronously, the storage trough 15 slides on the outer surface of the rod 20 under the action of the groove 19, and the No. 1 spring 21 is deformed by the force.

[0037] The flipping mechanism includes a mounting plate 23, which is fixedly mounted above the smear member 22. Shafts 26 are fixedly mounted on both sides of the mounting plate 23. The shafts 26 are arranged horizontally and connected to the material storage trough 15 through a sliding structure. The outer surface of the shaft 26 is provided with a rotating structure.

[0038] The sliding structure includes a mounting block 24 and a mounting groove 25 . The mounting groove 25 is provided on both sides of the material storage trough 15 . The mounting block 24 is slidably mounted inside the mounting groove 25 . The mounting block 24 is rotatably connected to the shaft 26 .

[0039] The rotating structure includes a number two gear 27, which is fixedly sleeved on the outer surface of the shaft 26. A fixed plate 28 is fixedly installed above the working platform 14, and a plurality of groups of teeth 29 are fixedly installed above the fixed plate 28. The teeth 29 are engaged with the number two gear 27. A fixed block 30 is fixedly installed on the side of the fixed plate 28 away from the storage trough 15. Both sides of the upper side of the fixed block 30 are designed in an arc shape, and the fixed block 30 is engaged with the number two gear 27.

[0040] Specifically, when the support plate 3 drives the material storage trough 15 to move synchronously, under the action of the fixed plate 28, the second gear 27 engages with the teeth 29, and the second gear 27 drives the shaft 26 to rotate. At this time, the shaft 26 drives the smear member 22 to flip through the mounting plate 23. After the smear member 22 is above the mounting plate 23, the second gear 27 contacts the fixed block 30. Since the two ends of the fixed block 30 are designed in a circular arc shape, the fixed block 30 can drive the second gear 27 to move upward. At this time, the shaft 26 drives the mounting block 24 to move upward inside the mounting groove 25, and then the mounting plate 23 drives the smear member 22 to move upward, so as to facilitate the smearing of the glue to the inside of the groove body. After the smearing is completed, the second gear 27 continues to move along the top of the fixed block 30. At this time, the mounting plate 23 drives the smear member 22 to move downward, so that the smear member 22 and the optical device accessories are separated.

[0041] The lifting mechanism includes a movable groove 31, which is opened on the side of the storage trough 15 close to the limit plate 17. A support rod 32 is fixedly installed inside the movable groove 31, and the outer surface sliding sleeve of the support rod 32 is provided with a support block 33. The support block 33 and the limit plate 17 are fixedly connected. The outer surface sliding sleeve of the support rod 32 is provided with a No. 2 spring 34, and the No. 2 spring 34 and the support block 33 are fixedly connected. A trigger member 35 is fixedly installed above the working platform 14, and the side of the trigger member 35 close to the support block 33 is inclined, and the trigger member 35 and the support block 33 are in contact and cooperate.

[0042] Specifically, after the coating is completed, the material storage trough 15 drives the support block 33 to contact the trigger member 35. Since the trigger member 35 is inclined on the side close to the support block 33, under the action of the movable groove 31, the trigger member 35 can push the support block 33 to move downward on the outer surface of the support rod 32. At this time, the support block 33 drives the limit plate 17 to move downward, and the No. 2 spring 34 is deformed under the force. When the limit plate 17 is separated from the push block 18, the support plate 3 is separated from the material storage trough 15. At this time, under the elastic force of the No. 1 spring 21, the No. 1 spring 21 drives the material storage trough 15 to reset.

[0043] A brush 16 is fixedly mounted on one side of the storage trough 15 close to the support plate 3 .

[0044] Specifically, when the support plate 3 drives the optical device accessory to move toward the material storage trough 15 , the brush 16 contacts the surface of the optical device accessory, and the brush 16 can clean the surface of the optical device accessory.

[0045] Working principle: The mobile trolley 2 drives the support plate 3 to move along the track 1 through the plate 5. The optical device accessories are placed above the working platform 14. The track 1 above the optical device accessories is designed to be arc-shaped. When the support plate 3 moves to above the optical device accessories, the support plate 3 drives the suction cup 4 to move downward, so that the suction cup 4 can adsorb the optical device accessories. Then the support plate 3 drives the optical device accessories to move upward through the suction cup 4. When the support plate 3 drives the optical device accessories to move toward the storage trough 15, the brush 16 contacts the surface of the optical device accessories, and the brush 16 can clean the surface of the optical device accessories.

[0046] When the optical device accessories move to the top of the storage trough 15, the push block 18 contacts the limit plate 17, and the support plate 3 can drive the storage trough 15 to move synchronously. Under the action of the groove 19, the storage trough 15 slides on the outer surface of the rod 20. At this time, the No. 1 spring 21 is deformed by the force.

[0047] At the same time, under the action of the fixing plate 28, the second gear 27 meshes with the teeth 29, and the second gear 27 drives the shaft 26 to rotate. At this time, the shaft 26 drives the smear member 22 to flip through the mounting plate 23. After the smear member 22 is above the mounting plate 23, the second gear 27 contacts the fixing block 30. Since the two ends of the fixing block 30 are designed in a circular arc shape, the fixing block 30 can drive the second gear 27 to move upward. At this time, the shaft 26 drives the mounting block 24 to move upward inside the mounting groove 25, and then the mounting plate 23 drives the smear member 22 to move upward, so as to facilitate the application of glue to the inside of the groove body. After the application is completed, the second gear 27 continues to move along the top of the fixed block 30. At this time, the mounting plate 23 drives the smear member 22 to move downward, so that the smear member 22 and the optical device accessories are separated.

[0048] After the smearing is completed, the material storage trough 15 drives the support block 33 to contact the trigger member 35. Since the trigger member 35 is inclined on the side close to the support block 33, under the action of the movable groove 31, the trigger member 35 can push the support block 33 to move downward on the outer surface of the support rod 32. At this time, the support block 33 drives the limit plate 17 to move downward, and the No. 2 spring 34 is deformed under the force. When the limit plate 17 is separated from the push block 18, the support plate 3 is separated from the material storage trough 15. At this time, under the elastic force of the No. 1 spring 21, the No. 1 spring 21 drives the material storage trough 15 to reset.

[0049] The support plate 3 is separated from the material storage trough 15, and the support plate 3 continues to move. At this time, the No. 1 gear 7 is in contact with the rack 8. Since the No. 1 gear 7 and the rack 8 are meshed, the No. 1 gear 7 can drive the support plate 3 to rotate one hundred and eighty degrees through the rotating shaft 6. When the support plate 3 moves to the bottom of the inclined plate 12, the vertical plate 11 is in contact with the inclined plate 12. The end face of the side of the inclined plate 12 close to the vertical plate 11 is inclined. Therefore, the inclined plate 12 pushes the horizontal plate 10 to move downward through the vertical plate 11, and the horizontal plate 10 drives the blanking piece 9 to move synchronously. At this time, the elastic piece 13 is deformed by the force, and the blanking piece 9 places the glass slide inside the groove body on the optical device accessory.
