Description

Technical Field

[0001] The present invention relates to the field of transfer equipment, and in particular to a transfer equipment for optical lenses with a protection function. Background Art

[0002] Optical lenses play a crucial role in astronomical telescopes for observing celestial bodies, performing functions such as light collection, imaging, and magnification. In the production process of optical lenses, they first go through processes such as forming, grinding, polishing, and cleaning. After these preliminary processing steps are completed, the lenses are transferred to a dedicated workshop for the next coating process to ensure their required optical properties.

[0003] Moreover, after the lenses are polished and cleaned, they need to wait for the water to drain before being transferred, which takes a relatively long time. Existing transfer equipment adds a drying function to complete the drying operation while transferring, thereby shortening the process flow. At the same time, when passing through the workshop door frame or low-lying areas during the transfer process, there will be bumps and vibrations, resulting in the lenses being knocked and damaged.

[0004] Considering that when the existing transfer equipment for lenses uses hot air to dry the lenses, since it is necessary to fully dry all surfaces of the lenses, hot air pipelines are added to the upper cover for fixing the lenses to dry the upper surface. However, due to the connection between the hot air pipelines and the upper cover, the upper cover cannot be directly removed and taken out of the transfer equipment. During the process of loading the lenses into the transfer equipment, when operating, one hand needs to lift the upper cover, and the other hand places the lens. Since the lenses of astronomical telescopes are large in size and have a high smoothness after surface polishing, it is extremely easy for the lens to slip and break during manual single-handed operation.

[0005] In summary, the present application proposes a transfer equipment for optical lenses with a protection function to improve the above-mentioned technical problems. Summary of the Invention

[0023] Embodiment 1 A transfer device for optical lenses with protection function, referring to Figures 1-9 as shown, includes a transfer cart 1 and a transfer box 2; the transfer box 2 is placed on the transfer cart 1, and the transfer box 2 is provided with an openable and closable warehouse door 21; It further includes a bearing tray 3, a cover plate 5, a slide rail 6, a first sliding plate 7, a first T-shaped insert block 8, a first spring 9, a second sliding plate 10, a second T-shaped insert block 11, a second spring 12, a drying unit and a local drying unit; A number of vertically slidable bearing trays 3 are connected inside the transfer box 2; A cover plate 5 is provided above each bearing tray 3; Two slide rails 6 are fixedly connected to the transfer box 2; A number of square holes 61 are opened in the slide rail 6; Each bearing tray 3 is fixedly connected with two first sliding plates 7, and the first sliding plates 7 are slidably connected with the slide rail 6; A first T-shaped insert block 8 is slidably connected to each first sliding plate 7; Each first T-shaped insert block 8 is fixedly connected with a first spring 9, and the first spring 9 is fixedly connected with the first sliding plate 7. The bearing tray 3 is fixed by inserting the first T-shaped insert block 8 into the square hole 61; Each cover plate 5 is fixedly connected with two second sliding plates 10, and the second sliding plates 10 are slidably connected with the slide rail 6; A second T-shaped insert block 11 is slidably connected to each second sliding plate 10; Each second T-shaped insert block 11 is fixedly connected with a second spring 12, and the second spring 12 is fixedly connected with the second sliding plate 10. The cover plate 5 is fixed by inserting the second T-shaped insert block 11 into the square hole 61; The transfer cart 1 is connected with a drying unit; A local drying unit is connected inside the transfer box 2.

[0024] It further includes a pressing plate 101 and a pressing block 102; A pressing plate 101 is slidably connected to each slide rail 6, and the pressing plate 101 slides in the square hole 61; Each pressing plate 101 is fixedly connected with a pressing block 102, and the pressing block 102 penetrates through the transfer box 2.

[0025] It further includes an elastic telescopic rod 4 and a buffer sponge 103; A number of elastic telescopic rods 4 are fixedly connected to each bearing tray 3, and the telescopic parts of all the elastic telescopic rods 4 on the same bearing tray 3 are jointly fixedly connected with the cover plate 5; A buffer sponge 103 is fixedly connected to the bottom of the transfer box 2.

[0026] The drying unit includes a hot air blower 111, an air delivery pipe 112, an annular pipe 113 and a first positioning post 114; The bearing tray 3 is hollow, and a filter screen 31 is arranged in its hollow part; A number of pressing rods 51 are fixedly connected to the bottom of the cover plate 5, and a silica gel cushion block is arranged at the bottom of the pressing rod 51. The lens is fixed by the silica gel cushion block of the pressing rod 51 to prevent damage to it; The hot air blower 111 is installed at the bottom of the transfer cart 1; The hot air blower 111 is communicated with an air delivery pipe 112; The air delivery pipe 112 is communicated with an annular pipe 113; Four first positioning posts 114 are fixedly connected to the annular pipe 113. The first positioning post 114 is of a hollow structure and is communicated with the annular pipe 113; A number of through holes 22 are opened at the bottom of the transfer box 2, and the through holes 22 correspond to the first positioning posts 114.

[0027] The upper end of the cover plate 5 is set in a conical shape that is high in the middle and low around. During the drying process, the conical cover plate 5 can guide the dripping water droplets and drain them to the surroundings, preventing the water droplets from falling on the lens surface and reducing the drying efficiency of the lens.

[0028] After the lens has completed processes such as forming, grinding, polishing, and cleaning, it needs to be transferred to a dedicated workshop for the next coating process to ensure that it has the required optical properties. The following are the specific working steps for lens transfer: First, manually open the door 21 of the transfer box 2. Then, lift the cover plate 5 with one hand, separating the cover plate 5 from the carrier tray 3. Next, manually place the lens in the carrier tray 3 with the other hand. Then, manually lower the cover plate 5 again to fix the lens in the carrier tray 3. And perform the same operation to place the lenses in the remaining carrier trays 3 in sequence. After the lenses are placed, manually close the door 21, and then place the transfer box 2 containing the lenses on the transfer cart 1. By pushing the transfer cart 1 to move, the transfer box 2 is transferred to the subsequent processing workshop. When placing the transfer box 2 on the transfer cart 1, the positioning post one 114 on the transfer cart 1 is inserted into the through hole 22 of the transfer box 2 to position the placement position of the transfer box 2. During the subsequent transfer process, control the hot air blower 111 to work, and pass the hot air through the air delivery pipe 112, the annular pipe 113, and the positioning post one 114 in sequence and into the interior of the transfer box 2. And a filter screen 31 is provided at the bottom of the carrier tray 3, and the cover plate 5 fixes the lens through a plurality of pressing rods 51. The hot air is evenly diffused to the lens surface through the filter screen 31, thereby heating and drying the lens, so that the drying of the lens can be completed during the transfer process, improving the overall processing efficiency of the lens. And the upper surfaces of each lens can be specifically dried through the local drying unit, improving the drying efficiency of the lens and ensuring that the lens can be fully dried during the transfer process.

[0029] However, considering the large size of the lens and the high smoothness after surface polishing, during the process of placing the lens, it is very easy for the lens to slip and break when manually operated with only one hand; to solve the above problems, first, manually hold the two sliding plates II 10 on the cover plate 5 with both hands, then use the thumb to move the T-shaped insert block II 11 in the direction close to the cover plate 5, and the spring II 12 is compressed. When the T-shaped insert block II 11 disengages from the square hole 61 of the slide rail 6, the sliding plate II 10 loses its restriction. Then, manually drive the sliding plate II 10 and the connected cover plate 5 to move upward along the slide rail 6, and the elastic telescopic rod 4 is stretched, so as to separate the cover plate 5 from the bearing tray 3. And when the T-shaped insert block II 11 is aligned with the square hole 61 on the slide rail 6, the manual operation stops releasing the T-shaped insert block II 11, and the spring II 12 rebounds to push the T-shaped insert block II 11 back to insert into the square hole 61, fixing the cover plate 5 separated from the bearing tray 3. Then, manually hold the lens steadily with both hands, place the lens in the bearing tray 3. After the lens is placed, manually hold the sliding plate II 10 again, and move the T-shaped insert block II 11 to disengage from the square hole 61, lower the cover plate 5 to press the lens, so as to fix the lens in the bearing tray 3. Then, manually release the T-shaped insert block II 11, and the T-shaped insert block II 11 is inserted into the corresponding square hole 61 under the action of the spring II 12 to limit the cover plate 5. Subsequently, perform the same operation as above to complete the placement and fixation of all lenses one by one; by inserting the T-shaped insert block II 11 into the square hole 61 to fix the separated cover plate 5, both hands can be liberated when placing the lens later, which is convenient for placing the lens with both hands and avoids the lens from slipping or breaking due to single-handed operation.

[0030] Meanwhile, to optimize the transfer efficiency, multiple bearing trays 3 are usually configured in the transfer box 2, so that more optical lenses can be transferred at the same time. However, when a large number of bearing trays 3 are arranged in the transfer box 2, the distance between adjacent bearing trays 3 will become smaller, resulting in that when manually placing the lens, the bearing tray 3 and the cover plate 5 cannot be fully opened, which brings inconvenience to manually placing the lens; therefore, initially, as Figure 8As shown, all the bearing trays 3 and cover plates 5 are located in the lower half of the transfer box 2. When placing the lenses, they are placed one by one from top to bottom manually. Moreover, when the lens is placed in the bearing tray 3, the operator holds the sliding plate 1 7 and the sliding plate 2 10 with both hands and pushes the T-shaped insert block 1 8 and the T-shaped insert block 2 11 to move out of the square hole 61. The first spring 9 and the second spring 12 contract, and then drive the bearing tray 3 and the cover plate 5 to move upward, moving the bearing tray 3 and the cover plate 5 with the lens placed to the upper side inside the transfer box 2, thus separating them from the bearing tray 3 and the cover plate 5 where the next lens needs to be placed, so as to facilitate the subsequent placement of the lenses. Then, release the T-shaped insert block 1 8 and the T-shaped insert block 2 11, so that they are reset under the action of the first spring 9 and the second spring 12 respectively and reinsert into the corresponding square holes 61 to fix the moved bearing tray 3 and cover plate 5. Then, gradually place the lenses in the other bearing trays 3 and cover plates 5 from top to bottom and gradually adjust the positions of the bearing tray 3 and the cover plate 5. Finally, as Figure 2 shown, the placement of the lenses is completed, and the bearing trays 3 and the cover plates 5 are evenly distributed in the transfer box 2, and then the subsequent transfer is carried out. During the process of placing the lenses, by pushing the T-shaped insert block 1 8 and the T-shaped insert block 2 11 to move out of or insert into the square hole 61, the positions of the bearing tray 3 and the cover plate 5 are adjusted to facilitate the placement of the lenses. When the transfer of the lenses is completed and the lenses need to be taken out, the operator adjusts the positions of the lowermost bearing tray 3 and the cover plate 5 to move them downward to separate them from the bearing tray 3 and the cover plate 5 above, increasing the distance between them, so as to facilitate the separation of the lowermost bearing tray 3 and the cover plate 5, and the lenses are taken out in sequence from bottom to top.

[0031] Moreover, after the lens is taken out, it is necessary to manually adjust the positions of each supporting tray 3 and the cover plate 5 one by one to reset them to the lower half position of the transfer box 2 for subsequent lens placement. The method of adjusting one by one is cumbersome. In this regard, when all the supporting trays 3 and the cover plates 5 need to be reset to the initial state, the pressing block 102 is directly pressed manually. The pressing block 102 drives the pressing plate 101 to move in the slide rail 6. The pressing plate 101 moves into the square hole 61, thereby ejecting all the T-shaped inserts one 8 and the T-shaped inserts two 11 inserted into the square hole 61. After the sliding plate one 7 and the sliding plate two 10 lose the fixation of the T-shaped inserts one 8 and the T-shaped inserts two 11, they slide down along the slide rail 6, thereby driving all the supporting trays 3 and the cover plates 5 to move down and reset to the initial state for subsequent lens placement; by moving the pressing plate 101, all the T-shaped inserts one 8 and the T-shaped inserts two 11 are ejected, so that all the supporting trays 3 and the cover plates 5 can quickly move down and reset, without the need for manual adjustment one by one, and the operation is more convenient; at the same time, a buffer sponge 103 is arranged at the bottom of the transfer box 2. During the process of the supporting tray 3 and the cover plate 5 moving down and resetting, the buffer sponge 103 buffers them, and the adjacent supporting trays 3 and the cover plates 5 are buffered by the elastic telescopic rods 4 to prevent the supporting trays 3 and the cover plates 5 from colliding and damaging each other during the process of quickly resetting.

[0032] Embodiment 2 On the basis of Embodiment 1, with reference to Figure 1 , Figure 2 , Figure 4 and Figures 9-14 as shown, it further includes a slider 201, a fixing frame 202, a positioning post two 203, a fixing round rod 211, an inserting rod 212, a movable rod 213 and a spring three 214; a vertically slidable slider 201 is connected to the transfer trolley 1; the slider 201 is fixedly connected with the fixing frame 202; a plurality of positioning posts two 203 are fixedly connected to the top of the transfer box 2. The positioning post two 203 is of a hollow structure and is communicated with the inside of the transfer box 2, and the positioning post two 203 corresponds to the position of the through hole 22; three fixing round rods 211 are fixedly connected to the outer surface of the transfer box 2, and the fixing round rods 211 are of a hollow structure; a movable rod 213 is slidably connected inside each fixing round rod 211; a spring three 214 is fixedly connected to each movable rod 213, and the spring three 214 is fixedly connected with the fixing round rod 211; three inserting rods 212 are fixedly connected to the fixing frame 202, and the inserting rods 212 correspond to the positions of the movable rods 213.

[0033] It also includes a ventilation pipe 215 and an airbag 1 221; the movable rod 213 is arranged in a hollow structure; the annular pipe 113 is communicated with a plurality of ventilation pipes 215, the ventilation pipes 215 are located below the fixed round rod 211, and an electric control valve is arranged on the ventilation pipes 215; a plurality of through holes are formed in the transfer cart 1, and the through holes are located above the ventilation pipes 215; a plurality of airbags 1 221 are fixedly connected to the upper side and the lower side of each movable rod 213 respectively, and the airbags 1 221 are communicated with the movable rod 213.

[0034] The local drying unit includes a connecting pipe 222, a round pipe 223, a thin pipe 1 224, a thin pipe 2 225 and an airbag 2 226; the fixed round rod 211 is provided with a strip-shaped groove 21101; one of the movable rods 213 is communicated with a connecting pipe 222; the round pipe 223 is fixedly connected inside the transfer box 2; the connecting pipe 222 passes through the strip-shaped groove 21101, penetrates through the transfer box 2 and is communicated with the internal round pipe 223, and the connecting pipe 222 is a flexible pipe; the round pipe 223 is communicated with a plurality of thin pipes 1 224; both the cover plate 5 and the pressing rod 51 are arranged in a hollow structure, the cover plate 5 is communicated with the pressing rod 51, and the thin pipe 1 224 is communicated with the cover plate 5; a plurality of air blowing holes 52 are formed in each pressing rod 51; the round pipe 223 is communicated with a plurality of thin pipes 2 225; an airbag 2 226 is fixedly connected to the bottom of each cover plate 5 respectively, the airbag 2 226 is communicated with the thin pipe 2 225, and both the thin pipe 1 224 and the thin pipe 2 225 are flexible pipes.

[0035] The airbag 2 226 is arranged in a ring shape and is located at the bottom edge of the cover plate 5. When the airbag 2 226 expands, it can fill and seal the gap between the cover plate 5 and the bearing tray 3, so that the lens inside the bearing tray 3 is in a closed space, which can prevent the fragments from scattering due to vibration when the lens is accidentally broken and reduce the difficulty of subsequent manual cleaning.

[0036] The bearing tray 3 and the filter screen 31 are arranged in a detachable connection. After the transfer is completed, when the lens is damaged, the artificial person can remove the filter screen 31 to take out and clean the broken lens on the filter screen 31.

[0037] On the basis of the above embodiments, when the transfer box 2 equipped with lenses is placed on the transfer cart 1 for transfer, in order to improve efficiency, usually two or more transfer boxes 2 are stacked and transported simultaneously. However, during the stacking and transfer process, the upper transfer box 2 may fall due to vibration; therefore, when the first transfer box 2 is positioned by the first positioning post 114 and placed on the transfer cart 1 manually, then the second transfer box 2 is placed on the upper side of the first transfer box 2 manually, and the second positioning post 203 on the first transfer box 2 is inserted into the through hole 22 of the second transfer box 2, so as to position and fix the two stacked transfer boxes 2. After the stacking is completed, the slider 201, the fixing frame 202 and the insertion rod 212 are pushed downward manually. When the fixing frame 202 contacts the upper side of the second transfer box 2, the movement stops. At this time, the two stacked transfer boxes 2 are limited and fixed by the fixing frame 202; at the same time, during the downward movement of the fixing frame 202, the fixing frame 202 drives the insertion rod 212 to move downward and insert into the fixed round rod 211 on the second transfer box 2, and docks with the movable rod 213 inside it. As the insertion rod 212 continues to move downward, the insertion rod 212 drives the movable rod 213 of the second transfer box 2 to move downward, so that it is inserted into the fixed round rod 211 of the first transfer box 2, and docks with the movable rod 213 in the fixed round rod 211, and drives the movable rod 213 on the first transfer box 2 to move downward. The third spring 214 is compressed. The movable rod 213 on the first transfer box 2 moves downward through the through hole of the transfer cart 1 and is inserted into the ventilation pipe 215, and is inserted and communicated with the ventilation pipe 215. At this time, the lower end of the movable rod 213 of the second transfer box 2 is inserted into the fixed round rod 211 of the first transfer box 2, and pushes the lower end of the movable rod 213 of the first transfer box 2 to be inserted into the through hole of the transfer cart 1, so as to realize the fixed connection of the two stacked transfer boxes 2, thereby preventing the upper transfer box 2 from falling due to vibration during the transfer; and, the movable rod 213 is set as a hollow structure. When the movable rod 213 is inserted into the ventilation pipe 215 and is inserted and communicated with the ventilation pipe 215, the movable rod 213 on the second transfer box 2 is docked and communicated with the movable rod 213 on the first transfer box 2. After the electric control valve of the ventilation pipe 215 is manually opened, hot air enters the two movable rods 213 through the ventilation pipe 215 and enters the airbag 221 on the movable rod 213, so that it expands and fixes the two docked movable rods 213. Thus, when passing through the workshop door frame or low-lying area, the airbag 221 forms a damping structure after expansion, effectively absorbing the vibration energy during the transfer process, resulting in damage to the internal lenses; and the second positioning post 203 is set as a hollow structure, and the hot air entering the first transfer box 2 can enter the second transfer box 2 through the second positioning post 203 to dry the lenses inside it.

[0038] Moreover, in order to further improve the fixing effect on the lens, when gas is introduced into the movable rod 213, it is simultaneously introduced into the circular tube 223 through the connecting pipe 222 and into the airbag two 226 through the thin tube two 225, causing the airbag two 226 to expand and clamp and fix the lens placed on the bearing tray 3, thereby enhancing the clamping effect on the lens and preventing the lens from being bumped and damaged due to vibration. Moreover, the airbag two 226 is located at the edge of the bottom of the cover plate 5, and when it expands, it can fill and seal the gap between the cover plate 5 and the bearing tray 3, preventing the fragments from scattering due to vibration after the lens is accidentally broken and reducing the difficulty of manual cleaning. At the same time, the bearing tray 3 is detachably connected with a filter screen 31. After the transportation is completed, when the lens is damaged, after the filter screen 31 is manually removed, the lens fragments can be directly poured or rinsed off.

[0039] The following are the specific working steps of the local drying unit. The cover plate 5 and the pressing rod 51 are provided with a hollow structure. During the process of the airbag two 226 expanding to fix the lens, part of the gas in the circular tube 223 is introduced into the cover plate 5 and the pressing rod 51 through the thin tube one 224 and blown out from the air blowing holes 52 to blow-dry the upper surface of the lens, thereby improving the drying efficiency during the lens transportation.

The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
