Description

Technical Field

[0001] The present invention relates to the field of lens coating, and particularly to an auxiliary device for processing small-diameter lenses. Background Art

[0002] Small-diameter lenses usually refer to optical lenses with a relatively small diameter and are widely used in various precision optical instruments and devices. For the coating of small-diameter lenses, they need to be placed on a coating umbrella, and then the coating umbrella is installed in a coating chamber for coating. The small-diameter lenses are relatively small in size, and people need to place the small-diameter lenses separately on the object trays of the coating umbrella. Multiple accommodating grooves are provided on the object trays, and the small-diameter lenses are placed on the accommodating grooves. In the prior art, it is necessary to manually transfer the small-diameter lenses one by one from the storage rack to the accommodating grooves, which is rather cumbersome. Therefore, an auxiliary device for processing small-diameter lenses is designed now, which can replace manual operation and automatically place the small-diameter lenses on the object trays.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the processing flow of small-diameter lenses, the cleaned small-diameter lenses need to be coated. After cleaning, the small-diameter lenses are usually neatly and vertically placed on the storage rack 101, and then they need to be moved into the coating chamber to complete the coating process (the outer part of the small-diameter lens is installed together with the mold, so when the small-diameter lens is placed on the storage rack 101, the mold at the edge directly contacts the storage rack 101, while the small-diameter lens does not directly contact the storage rack 101).

[0025] However, in the prior art, the operator has to manually remove the small-diameter lens from the storage rack 101 and place it on the tray 102 of the coating umbrella. This process is both cumbersome and time-consuming and laborious. For this reason, in this embodiment, an auxiliary device for processing small-diameter lenses is designed to achieve automatic transfer of the lenses without manual operation, thereby significantly improving work efficiency and reducing labor intensity.

[0026] As Figure 1 - Figure 2 shown, it includes a base 1 for supporting the whole. A rodless cylinder 2 is provided on the base 1. The rodless cylinder 2 serves as a power source to replace manual operation by the operator. A guide circular plate 5 is fixedly connected to the rodless cylinder 2 through a slider 3. After the rodless cylinder 2 is started, it can control the slider 3 to move up and down, and drive the guide circular plate 5 to move up and down together through the slider 3. A support column 4 is provided in the middle of the guide circular plate 5. The bottom end of the support column 4 is fixedly connected to the base 1. The support column 4 passes through the middle of the guide circular plate 5. A rotating sleeve 6 is provided outside the support column 4. The support column 4 passes through the rotating sleeve 6. The rotating sleeve 6 is concentric with the guide circular plate 5, and the top of the rotating sleeve 6 and the guide circular plate 5 are connected by circumferential sliding. A track is provided on the rotating sleeve 6. A column 9 is provided on one side of the rodless cylinder 2 close to the track. The end of the column 9 is located on the track. A clamping part for clamping the small-diameter lens is provided on the side of the rotating sleeve 6.

[0027] In this solution, the rodless cylinder 2 is used to control the rotating sleeve 6 to move upward. With the mutual cooperation between the column 9 and the track, the clamping part can be rotated from the lower right position to the upper front position. The storage rack 101 is placed in the lower right position, and the tray 102 is placed in the upper front position. After the clamping part clamps the small-diameter lens from the storage rack 101, it is transported to the tray 102. It can be seen that there is a certain height difference between the placement heights of the storage rack 101 and the tray 102 in this solution, abandoning the feeding method on the same horizontal line from right to front, and adopting the feeding method from right to front and from low to high. The reasons are as follows:

[0028] According to the way of placing small-diameter lenses on the storage rack 101, after the clamping part clamps a small-diameter lens, the clamping part needs to move upward to pick up the small-diameter lens by a certain distance before it can be separated from the storage rack 101. If the small-diameter lens is directly clamped and then rotated for material transfer on the same horizontal line, the mold at the edge of the small-diameter lens will collide with the storage rack 101 due to extrusion, and it will be blocked by the storage rack 101 and unable to achieve rotational material transfer. Therefore, the material transfer method of this solution is formulated according to the actual working conditions.

[0029] The track includes two vertical linear tracks 7 arranged on the side of the rotating sleeve 6. One vertical linear track 7 is arranged at the position on the left front side of the rotating sleeve 6 close to the guiding circular plate 5, and the other vertical linear track 7 is arranged on the front side of the rotating sleeve 6 away from the guiding circular plate 5. The two vertical linear tracks 7 are connected to an inclined track 8. When the guiding circular plate 5 moves upward to drive the rotating sleeve 6 and the track to move upward, under the mutual cooperation between the first column 9 and the track, the rotating sleeve 6 first moves vertically upward by a distance A (the length of A is equal to the length of the vertical linear track 7). Then, the first column 9 enters the inclined track 8 from the vertical linear track 7 and slides on the inclined track 8. The rotating sleeve 6 starts to rotate clockwise by 90° and moves vertically upward simultaneously. Subsequently, the first column 9 enters the vertical linear track 7 from the inclined track 8, and the rotating sleeve 6 stops rotating and continues to move upward by a distance A (the length of A is equal to the length of the vertical linear track 7). Then, the guiding circular plate 5 moves downward, so that the rotating sleeve 6 first moves vertically downward, and then moves vertically downward and rotates counterclockwise by 90° simultaneously, and returns to the state as Figure 1 shown.

[0030] In addition, it should be supplemented that:

[0031] The storage rack 101 is arranged on a mobile device, which is an external device. The mobile device can control the left and right movement of the storage rack 101, and can set a timer for the mobile device in advance. The action achieved is: after the clamping part clamps a small-diameter lens, the mobile device controls the storage rack 101 to move left by a certain distance, so that the next small-diameter lens moves to the specified position clamped by the clamping part;

[0032] The material tray 102 is arranged on a rotating device. The material tray 102 is provided with accommodating grooves at equal intervals in the circumferential direction. The rotating device can be set with a timer in advance. After the clamping part places the small-diameter lens on the accommodating groove, the rotating device automatically rotates to control the rotation of the material tray 102, so that the next accommodating groove is transferred to the specified position for discharging by the clamping part.

[0033] The clamping part includes a transfer rack 10 fixedly connected to the side of the rotating sleeve 6. A support body 11 is arranged on the side of the transfer rack 10 away from the rotating sleeve 6. A clamping block 12 is arranged on the support body 11. The clamping block 12 is slidably connected to the support body 11. The clamping block 12 is provided with a power source. The power source can drive the clamping block 12 to move towards the side close to each other to clamp the side of the mold for small-diameter lenses. The power source has a timing function. By timing the power source in advance, the following effect can be achieved: after the clamping block 12 moves to the specified clamping position, when the power source starts to work, the clamping block 12 moves to clamp the side of the mold for small-diameter lenses. Then, after the clamping block 12 moves to the specified position for discharging, the power source starts to control the clamping block 12 to move and release the mold for small-diameter lenses, so as to achieve the purpose of automatic material clamping and discharging.

[0034] The power source is a first motor 13. The first motor 13 is fixedly connected to the side of the transfer rack 10 close to the support body 11. When material needs to be clamped, the output shaft of the first motor 13 starts to rotate forward, and the grooved disk 14 connected to the output shaft of the first motor 13 rotates synchronously. The arc-shaped groove 15 arranged at the bottom of the grooved disk 14 rotates accordingly, driving the column body two 16 arranged on the arc-shaped groove 15 to start moving towards the side close to each other. Since the bottom of the column body two 16 is fixedly connected to the upper end position of the clamping block 12, when the column body two 16 moves towards the side close to each other, it will drive the clamping block 12 to move synchronously to achieve the purpose of clamping the small-diameter lens. Then, when the rotating sleeve 6 moves upward, it will drive the clamping part and the small-diameter lens upward together, so that the small-diameter lens is separated from the storage rack 101. Then, when the rotating sleeve 6 rotates clockwise and the small-diameter lens rotates clockwise to the specified discharging position, the output shaft of the first motor 13 starts to rotate in the reverse direction, so that the clamping block 12 moves towards the side away from each other to release the small-diameter lens, and the purpose of discharging can be achieved.

[0035] The small-diameter lenses after cleaning are usually neatly and vertically placed on the storage rack 101, and are placed flat after being transferred to the accommodation groove of the object tray 102. In the above solution, when the clamping part clamps the small-diameter lenses and conveys them above the accommodation groove, the small-diameter lenses are all in the vertical direction. If it is necessary to pick up the small-diameter lenses vertically and put them down flat, this is a problem that needs to be further solved in this embodiment. The following solution is adopted:

[0036] Such as Figure 3As shown, the guiding body 17 is fixedly connected to the bottom of the supporting body 11. A shaft rod 20 is provided on the guiding body 17, and the shaft rod 20 is rotatably connected to the guiding body 17. Symmetrically arranged chucks 18 are provided on the shaft rod 20. The chucks 18 replace the function of the clamping blocks 12 in the previous text. The chucks 18 are rotatably connected to the clamping blocks 12. When the clamping blocks 12 move, they will drive the chucks 18 to move together. The chucks 18 can realize the functions of clamping and releasing materials. When the chucks 18 rotate along the axial direction of the shaft rod 20, the clamping blocks 12 play a guiding role for the chucks 18. Therefore, after the chucks 18 move to the designated position for discharging, by driving the shaft rod 20 to rotate 90°, the chucks 18 can drive the small-diameter lens to rotate 90°. The small-diameter lens changes from a vertical state to a flat state. At this time, the small-diameter lens is directly above the vertical groove. Then, after the chucks 18 release the small-diameter lens, the small-diameter lens can vertically fall onto the vertical groove, thereby realizing the function of vertically picking up and flatly placing the small-diameter lens. A slat 21 is arranged on the side of the shaft rod 20. The slat 21 is slidably connected to the chucks 18. Through the slat 21, the chucks 18 can not only slide horizontally on the shaft rod 20, but also be driven to rotate by the rotation of the shaft rod 20;

[0037] As Figure 3 shown, rubber plates 19 are connected to the sides of the chucks 18 that are close to each other. When the chucks 18 clamp the edge of the mold of the small-diameter lens, by providing the rubber plates 19, it can be avoided that the chucks 18 directly contact the mold of the small-diameter lens, reducing the wear of the mold edge;

[0038] As Figure 3 shown, how to drive the shaft rod 20 to rotate was not mentioned in the previous text. Conventionally, a new power component is generally reconnected. However, in this embodiment, no new power component is used for driving. Instead, the power of the upward movement of the rotating sleeve 6 is utilized for driving, which can save costs and improve the coherence of the entire solution at the same time:

[0039] The gear 22 is fixedly connected to the end of the shaft rod 20. A rack 23 meshes with the gear 22. The rack 23 is slidably connected to the transfer rack 10. An extrusion spring 24 is arranged above the rack 23. The extrusion spring 24 keeps the pressing ring 25 jacked up upward. One end of the rack 23 away from the gear 22 is fixedly connected with a pressing ring 25. A pressing frame 26 is arranged on the support column 4. After the rotating sleeve 6 drives the transfer rack 10 and the clamping part to rotate clockwise to the discharging position, the pressing ring 25 is exactly below the pressing frame 26. Then, the rotating sleeve 6 will continue to drive the transfer rack 10 and the clamping part to move upward. The pressing ring 25 will be blocked by the pressing frame 26 and cannot move upward. The rack 23 arranged on the pressing ring 25 also stops moving upward. However, the transfer rack 10 continues to drive the shaft rod 20 and the gear 22 to move upward. At this time, the gear 22 will rotate. After the transfer rack 10 moves to the uppermost position, the gear 22 drives the shaft rod 20 to rotate 90°. As a result, the chuck 18 rotates the small-diameter lens into a flat state. Subsequently, after the chuck 18 releases the small-diameter lens, the transfer rack 10 starts to descend. The extrusion spring 24 jacks up the pressing ring 25 and the rack 23 to reset, so that the chuck 18 rotates and resets.

[0040] The rotating device includes a support frame 27. The support frame 27 is fixed on the base 1. A sliding part 311 is arranged on the upper part of the support frame 27. A support disk 31 for supporting the object disk 102 is arranged at the top of the sliding part 311. After the object disk 102 is placed in the support disk 31, the rubber ring arranged above the support disk 31 can limit the object disk 102 from moving out upward, but it will not affect people to manually take out the object disk 102.

[0041] As Figure 4 shown, a hollow column 30 is arranged at the bottom of the object disk 102. A rotating shaft 29 is arranged in the hollow column 30. The rotating shaft 29 is slidably connected in the hollow column 30. A second motor 28 is arranged on the support frame 27. The output shaft of the second motor 28 is fixedly connected with the hollow column 30. When the second motor 28 works, it can drive the hollow column 30 to rotate through the rotating shaft 29, so that the object disk 102 rotates. When the object disk 102 is taken out upward, the hollow column 30 and the rotating shaft 29 will also be separated. The second motor 28 can be timed in advance.

[0042] As can be seen from the foregoing, after the transfer rack 10 drives the clamping part and the small-diameter lens to rotate above the object tray 102 and when it is necessary to adjust the state of the small-diameter lens, the transfer rack 10 still needs to continue to drive the clamping part and the small-diameter lens to move upward, so as to realize the rotation of the small-diameter lens into a flat state. After the small-diameter lens moves upward and rotates into a flat state, the distance between the small-diameter lens and the object tray 102 becomes farther and farther. In this way, when the small-diameter lens is put down, due to the relatively long distance, the small-diameter lens will always deflect when falling due to some inertia or external force reasons. In this way, when the small-diameter lens falls onto the receiving groove, there will be an uneven situation, which requires subsequent manual adjustment by people. In this way, there is still a problem of manual operation. Therefore, the following solution is proposed in this embodiment, aiming to shorten the falling height of the small-diameter lens:

[0043] The sliding member 311 is slidably connected to the support frame 27, the first moving column 33 is slidably connected to the base 1, the top of the moving column is fixedly connected with the ejecting body 32, the top of the ejecting body 32 is fixed to the support plate 31. After the small-diameter lens is adjusted to a flat state, the first moving column 33 can be driven to move upward to drive the ejecting body 32 to move upward. When the ejecting body 32 moves upward, it pushes the support plate 31 to move upward, and the support plate 31 drives the object tray 102 to move upward close to the small-diameter lens. In this way, the distance between the small-diameter lens and the receiving groove can be shortened. After the small-diameter lens is placed in the receiving groove, the first moving column 33 can be moved downward to reset, thereby driving the object tray 102 to move downward to reset; a first spring 34 is provided on the first moving column 33. The first spring 34 is designed to drive the first moving column 33 to maintain a downward state, and the first spring 34 can pull the first moving column 33 and the ejecting body 32 to move downward to reset. The lever 35 is arranged on one side of the base 1 close to the support frame 27. The lever 35 is rotatably connected to the base 1. The lever 35 contacts the bottom end of the first moving column 33. By pressing the position on the side of the lever 35 away from the first moving column 33, the lever 35 can be rotated to push the first moving column 33 to move upward, so as to achieve the purpose of pushing the first moving column 33;

[0044] This solution adopts the upward movement of the rotating sleeve 6 to achieve the effect of automatically adjusting the small-diameter lens to a flat state, and adopts the downward movement of the rotating sleeve 6 to achieve the effect of automatically driving the object tray 102 to rise and shorten the distance from the small-diameter lens. The solution is as follows:

[0045] As Figure 2 shown, a second moving column 36 is slidably connected to one side of the base 1 close to the lever 35. The bottom of the second moving column 36 contacts the lever 35. A second spring 37 is wound around the second moving column 36. A first wedge block 38 is provided on the side of the second moving column 36 away from the lever 35. The first wedge block 38 is slidably connected to the second moving column 36. A third spring 39 is provided on the first wedge block 38. A second wedge block 40 is fixed to the side of the transfer rack 10. It also includes a column 41 fixed to one side of the base 1 close to the first wedge block 38;

[0046] When the transfer rack 10 drives the clamping part and the small-diameter lens to rotate above the object tray 102, the transfer rack 10 also drives the second wedge block 40 to move to the position below the first wedge block 38 at the same time. Then, when the transfer rack 10 drives the second wedge block 40 and the small-diameter lens to move upward, the second wedge block 40 will not contact the column 41. When the second wedge block 40 contacts the first wedge block 38, it will push the first wedge block 38 to move leftward, and the third spring 39 is stretched. After the second wedge block 40 moves above the first wedge block 38, the third spring 39 drives the first wedge block 38 to move rightward and reset. At this time, the small-diameter lens is rotated and adjusted to a flat state. Then, when the transfer rack 10 moves downward, it will drive the second wedge block 40 to move downward. The second wedge block 40 will abut against the top surface of the first wedge block 38 and push the first wedge block 38 to move downward. The first wedge block 38 will drive the second moving column 36 to move downward. When the second moving column 36 moves downward, it will squeeze the side of the lever 35 away from the first moving column 33, and the second spring 37 is compressed. In this way, the lever 35 can be rotated, and then the object tray 102 is pushed upward to shorten the distance from the small-diameter lens, so as to smoothly place the small-diameter lens into the accommodating groove. When the first wedge block 38 moves downward and contacts the column 41, the column 41 will push the first wedge block 38 to move leftward. After the first wedge block 38 moves leftward and disengages from the second wedge block 40, the second spring 37 will drive the second moving column 36 and the first wedge block 38 to move upward and reset, while the object tray 102 will descend and reset. In this way, the object tray 102 will not always remain in the upper position to prevent the transfer rack 10 from driving the clamping part to rotate and reset.

[0047] After the transfer rack 10 moves upward and the small-diameter lens is rotated to a flat state, the transfer rack 10 needs to move downward to make the object tray 102 rise. However, when the transfer rack 10 moves downward, the chuck 18 will rotate and reset, resulting in the small-diameter lens rotating back to the vertical state. Therefore, the following solution is proposed in this embodiment. After the small-diameter lens is rotated to a flat state, the position of the chuck 18 is automatically locked to prevent the chuck 18 from rotating and resetting when it descends, affecting the feeding of the small-diameter lens:

[0048] The n-shaped frame 42 is arranged on the top of the transfer rack 10. A moving body 43 is arranged on the transfer rack 10. The moving body 43 is slidably connected to the n-shaped frame 42. A fourth spring 44 is arranged on the moving body 43. Two symmetric wedge blocks three 45 are fixed on the top of the moving body 43. The pressing ring 25 is provided with an inclined surface. When the pressing ring 25 presses downward and the inclined surface of the pressing ring 25 contacts the wedge block three 45, it will push the wedge block three 45 to move towards the position close to the rotating sleeve 6. The moving body 43 moves together, so that the fourth spring 44 is compressed. After the pressing ring 25 moves below the wedge block three 45, the fourth spring 44 drives the moving body 43 and the wedge block three 45 to move and reset. The wedge block three 45 will abut above the pressing ring 25, making the pressing ring 25 unable to move upward and reset, and further making the small-diameter lens unable to rotate back to the vertical state, keeping the small-diameter lens in a flat state.

[0049] When the clamping part continues to clamp the next small-diameter lens, the pressing ring 25 needs to be unlocked to allow the chuck 18 to rotate and reset. Therefore, the following solution is adopted:

[0050] A wedge block four 46 is fixed to the side of the moving body 43, and a wedge block five 47 is arranged on one side of the base 1 close to the wedge block four 46, and the wedge block five 47 cooperates with the wedge block four 46.

[0051] After the transfer rack 10 rotates counterclockwise by 90°, the transfer rack 10 is just located above the wedge block five 47. The height of the wedge block five 47 will not block the transfer rack 10, so it will not affect the normal rotation of the transfer rack 10. Then when the transfer rack 10 moves down, the upper end of the wedge block five 47 slowly passes through the middle cavity position of the transfer rack 10. When the transfer rack 10 moves down, it drives the moving body 43 and the wedge block four 46 to move down. After the wedge block four 46 contacts the wedge block five 47, the wedge block four 46 is moved towards the position close to the rotating sleeve 6, and the wedge block four 46 drives the moving body 43 and the wedge block three 45 to move and release the pressing ring 25, so as to achieve the purpose of automatically releasing the pressing ring 25.

[0052] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
