Description

Technical Field

[0001] This invention belongs to the field of drying technology and relates to a drying system and method for optical spherical lenses. Background Technology

[0002] Optical spherical lenses are optical elements made from optical glass. During production, the optical glass rod is first cut into small cylinders, and then the small cylinders are rough polished and fine polished. After rough polishing and before fine polishing, they need to be washed with chemicals, washed with water, and dried.

[0003] Drying is typically done in an oven. Existing drying systems include an oven body and multiple layers of perforated shelves inside the oven. The semi-finished optical spherical lenses to be dried are placed in frames made of porous or mesh material, and then the frames are placed on the shelves. The drying system is then started, and the heating of the resistance wires and the hot air generated by the guide fan continuously blows onto the semi-finished optical spherical lenses to be dried. Because there is no hot air guiding device, the hot air is blown all over the shelves, resulting in chaotic airflow within the large oven body. This can easily lead to moisture retention and cannot guarantee that the optical spherical lenses in the frames on each shelf are dried at a uniform degree, resulting in poor drying effect, uneven surface drying, and low drying efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a drying system and method for optical spherical lenses, aiming to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a drying system for optical spherical lenses, comprising a housing, multiple porous shelves arranged sequentially inside the housing, multiple porous or mesh frames movably placed on the shelves, and a drying unit. The drying unit includes multiple air inlet pipes arranged sequentially inside the housing, multiple air outlet pipes arranged sequentially inside the housing, and a heating chamber. Both ends of each air inlet pipe are connected to the heating chamber and one side of the housing, respectively. Both ends of each air outlet pipe are connected to the heating chamber and the opposite side of the housing, respectively. The connection point between each air inlet pipe and each air outlet pipe and the housing is located between two adjacent shelves.

[0006] Furthermore, the shelf is provided with limit plates at the top of its four sides, the shelf is swayable, and the shelf is also provided with a swing mechanism to drive the shelf to swing back and forth.

[0007] Furthermore, each of the four corners of the shelf is provided with a suspension rod, which is hinged to the inner wall of the box or a rod provided on the inner wall of the box.

[0008] Furthermore, the swing mechanism includes a power assembly, which includes a drive assembly comprising a first power fan disposed within the end of the air inlet pipe near the frame, a first power rod connected to the center of the first power fan, a driving pinion coaxially disposed at the end of the first power rod away from the first power fan, a driven large gear meshing with the driving pinion, and a driven shaft disposed at the center of the driven large gear. The driven shaft provides power for the swing of the shelf. A first upright with a circular hole at the top is disposed within the end of the air inlet pipe near the frame, and the first power rod is movably fitted against the inner wall of the circular hole at the top of the first upright.

[0009] Furthermore, a second upright with a round hole at the top is provided at the end of the air inlet pipe near the frame. The power assembly also includes a second power fan, a second power rod connected to the center of the second power fan, and a transmission belt wound around the first power rod and the second power rod. The second power rod is movably fitted with the inner wall of the round hole at the top of the second upright.

[0010] Furthermore, the swing mechanism also includes a limiting ring with a limiting port on the inner wall of the box, an impact body slidably connected to the limiting port, and a driven push rod on the side of the driven shaft. The driven push rod can drive the impact body to move obliquely upward away from the shelf under the limitation of the limiting port. A third upright with a round hole at the top is provided in the end of the air inlet pipe near the frame. The driven shaft is in movable contact with the inner wall of the round hole at the top of the third upright. During the process of the impact body moving to the highest point and falling back to the lowest point, it will impact the side of the shelf.

[0011] Furthermore, the swing mechanism also includes a movable inclined rod rotatably connected to the first power rod, a movable spring, a push pinion coaxially mounted on the driven shaft, and an arc-shaped meshing body disposed on the side of the shelf. The two ends of the movable spring are respectively connected to the inner wall of the air inlet pipe and the end of the movable inclined rod away from the first power rod. The driven shaft is rotatably connected to the movable inclined rod. The arc-shaped meshing body includes an arc-shaped meshing portion at the bottom, a first protruding transition portion on one side, a second protruding transition portion on the other side, and a smooth portion at the top. The arc-shaped meshing portion, the first protruding transition portion, and the second protruding transition portion can all mesh with the push pinion. The edge of the arc-shaped meshing portion is arc-shaped with the hinge point between the suspension rod and the inner wall of the housing or the rod as its center. The side of the shelf away from the driven shaft has a set distance from the inner wall of the housing. The swing mechanism includes the following three states:

[0012] In the first state, the push pinion meshes with the arc-shaped meshing part, and the rotation of the push pinion can drive the shelf to swing. The end of the movable inclined rod away from the first power rod abuts against the crossbar provided on the inner wall of the air inlet pipe. The movable spring is in a horizontal state until the push pinion moves to the transition part with the first protrusion.

[0013] In the second state, the push pinion meshes with the first protruding transition portion, and the rotation of the push pinion drives the movable inclined rod to swing around the axis of the first power rod until the axis of the movable inclined rod and the axis of the movable spring are on the same straight line.

[0014] In the third state, the push pinion moves to the smooth part, and the plate falls back under the action of gravity until the push pinion meshes with the second protruding transition part. The rotation of the push pinion drives it to return to the first state.

[0015] Furthermore, the diameter of the driven large gear is 8 times or more the diameter of the driving small gear.

[0016] The present invention also provides a method for drying an optical spherical lens, comprising the following steps: placing the optical spherical lens to be dried in the frame of the drying system, then placing the frame on the shelf of the drying system, then turning on the power supply, and the drying system starting to operate for drying.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention provides a drying system and method for optical spherical lenses. The system includes a drying unit comprising multiple air inlet pipes and multiple air outlet pipes arranged sequentially in a vertical fashion. Hot air circulates repeatedly within independent hot air channels formed by the air inlet pipes, air outlet pipes, and the corresponding inner walls and shelves of the housing. This continuously dries and removes moisture from the surface of the optical spherical lens within the housing, resulting in high drying efficiency and preventing moisture retention. This solves the problem of low drying efficiency caused by unguided hot air being directly blown into the housing in existing technologies. Attached Figure Description

[0027] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the drying system and method for optical spherical lenses proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar parts.

[0028] Example 1

[0029] This invention provides a drying system for optical spherical lenses, with reference to... Figures 1 to 5The device includes a housing 1 (including an openable door 28), multiple perforated shelves 2 arranged vertically within the housing 1, multiple perforated or mesh frames 3 movably placed on the shelves 2, and a drying unit. The drying unit includes multiple air inlet pipes 4 arranged vertically, multiple air outlet pipes 5 arranged vertically, and a heating chamber 6. Both ends of each air inlet pipe 4 are connected to the heating chamber 6 and one side of the housing 1, respectively. Both ends of each air outlet pipe 5 are connected to the heating chamber 6 and the opposite side of the housing 1, respectively. The connection point between each air inlet pipe 4 and each air outlet pipe 5 and the housing 1 is located between two adjacent shelves 2. The heating chamber 6 is equipped with a heating device and a fan. When drying an optical spherical lens, the optical spherical lens is placed inside the multiple frames 3, and then the multiple frames 3 are placed on the shelves arranged vertically. On the shelf 2, the drying unit is then activated. The heating device (heating wire or heat exchange tube, which is a conventional existing device in the art) in the drying unit heats the air in the chamber 1, and then blows it out by the guide fan. Each air inlet pipe 4, the corresponding two adjacent shelves 2 and the inner wall of the chamber 1, and each air outlet pipe 5 form an independent hot air channel. In this way, the optical ball lenses in the frame 3 placed in each shelf 2 can be dried in sequence. Since the drying unit is set up with multiple air inlet pipes 4 and multiple air outlet pipes 5 arranged in sequence, the hot air circulates repeatedly in the independent hot air channels formed by the air inlet pipes 4, the air outlet pipes 5 and the corresponding inner wall of the chamber 1 and the shelf 2. In this way, the moisture on the surface of the optical ball lenses in the frame 3 can be dried and taken away continuously. The drying efficiency is high and the moisture does not remain. This solves the problem of low drying efficiency caused by the hot air not being guided and being blown directly into the chamber 1 in the prior art.

[0030] The drying system is also equipped with an exhaust pipe that connects to the outside, which can periodically extract water vapor from the chamber 1 to prevent water vapor from accumulating and affecting the drying effect.

[0031] refer to Figure 1 Alternatively, in step 2, a limiting plate 7 is provided at the top of the four sides of the shelf 2. The shelf 2 is swayable and includes a swaying mechanism that drives the shelf 2 to sway back and forth. Since the optical spherical lenses are small and nearly circular in shape, the optical spherical lenses piled up in the frame come into contact with each other. Hot air can remove the moisture from the surface of the optical spherical lenses, but the moisture on the contacting surfaces of the optical spherical lenses will remain. Therefore, a swaying mechanism is provided. During drying, the swaying mechanism drives the shelf 2 to sway back and forth. The frame 3 placed on the shelf 2 also swings accordingly or collides with the limiting plate 7 and shakes accordingly. In this way, the relative positions of the piled optical spherical lenses placed in the frame 3 will change. The contacting surfaces of the optical spherical lenses may separate during a certain sway, so the moisture on the surface will be removed by the hot air, thereby further improving the drying effect.

[0032] refer to Figure 7 Each of the four corners of the shelf 2 is provided with a suspension rod 8, which is hinged to the inner wall of the box 1 or a rod provided on the inner wall of the box 1. This structure enables the shelf 2 to swing.

[0033] refer to Figure 3 and Figure 4 The swing mechanism includes a power assembly, which includes a drive assembly comprising a first power fan 9 disposed at the end of the air inlet pipe 4 near the frame 3, a first power rod 10 connected to the center of the first power fan 9, a driving pinion 11 coaxially disposed at the end of the first power rod 10 away from the first power fan 9, a driven gear 12 meshing with the driving pinion 11, and a driven shaft 13 disposed at the center of the driven gear 12. The driven shaft 13 provides power for the swing of the shelf 2. The air inlet pipe 4 is provided with a first upright 14 with a round hole at the top at the end near the frame 3. The first power rod 10 is in contact with the inner wall of the round hole at the top of the first upright 14. When hot air blows to the end of the air inlet pipe 4 near the frame 3, it will blow the first power fan 9. When the first power fan 9 rotates, the first power rod 10 and the driving pinion 11 will rotate. The driven pinion and the driven shaft 13 will also rotate. The rotating driven shaft 13 provides power for the swing of the shelf 2 without the need for additional power, thus saving energy.

[0034] refer to Figure 3 and Figure 5 The air inlet pipe 4 is also provided with a second upright 15 with a round hole at the top inside the end near the frame 3. The power assembly also includes a second power fan 16, a second power rod 17 connected to the center of the second power fan 16, and a transmission belt 18 wound around the first power rod 10 and the second power rod 17. The second power rod 17 is in movable contact with the inner wall of the round hole at the top of the second upright 15. The second power fan 16 is blown by hot air and rotates, and the second power rod 17 also rotates, which can provide greater power for the swing of the shelf 2.

[0035] refer to Figure 3 and Figure 4The swing mechanism further includes a limiting ring 19 with a limiting port 27 disposed on the inner wall of the housing 1, an impact body 20 slidably connected to the limiting port 27, and a driven push rod 21 disposed on the side of the driven shaft 13. The driven push rod 21 can drive the impact body 20 to move obliquely upward away from the shelf 2 under the limitation of the limiting port 27. The air inlet pipe 4 is provided with a third upright 22 with a round hole at the top at the end near the frame 3. The driven shaft 13 and the round hole at the top of the third upright 22 are connected. The inner wall of the shelf 2 moves and fits together. As the impactor 20 moves to the highest point and falls back to the lowest point, it will impact the side of the shelf 2. Thus, the driven shaft 13 rotates, and the driven push rod 21 also rotates accordingly. When it rotates to a certain angle, it will contact the impactor 20 and push the impactor 20 to move obliquely upward away from the shelf 2. After rotating to a certain angle, the driven push rod 21 separates from the impactor 20. The impactor 20 falls back under the action of gravity. During the process of falling back to the lowest point, it will impact the side of the shelf 2, causing the shelf 2 to swing.

[0036] Specifically, the diameter of the driven large gear 12 is 8 times or more the diameter of the driving small gear 11. Meanwhile, the diameter of the driving small gear 11 is smaller and the diameter of the driven large gear 12 is larger, so that sufficient driving force can be provided for the rotation of the driven shaft 13 without the need for a large amount of wind.

[0037] Example 2

[0038] The difference from Example 1 is that, referring to Figure 6 and Figure 7 The swing mechanism further includes a movable inclined rod 23 rotatably connected to the first power rod 10, a movable spring 24, a push pinion 25 coaxially mounted on the driven shaft 13, and an arc-shaped meshing body 26 disposed on the side of the shelf 2. The two ends of the movable spring 24 are respectively connected to the inner wall of the air inlet pipe 4 and the end of the movable inclined rod 23 away from the first power rod 10. The driven shaft 13 is rotatably connected to the movable inclined rod 23. The arc-shaped meshing body 26 includes an arc-shaped meshing portion 26a at the bottom and a first… The raised transition portion 26b, the second raised transition portion 26c on the other side, and the smooth portion 26d at the top; the arc-shaped meshing portion 26a, the first raised transition portion 26b, and the second raised transition portion 26c can all mesh with the push pinion 25; the edge of the arc-shaped meshing portion 26a is arc-shaped with the hinge point of the suspension rod 8 and the inner wall of the housing 1 or the rod as the center; the side of the shelf 2 away from the driven shaft 13 has a set distance from the inner wall of the housing 1; the swing mechanism includes the following three states:

[0039] In the first state, the push pinion 25 meshes with the arc-shaped meshing part 26a. The rotation of the push pinion 25 can drive the shelf 2 to swing. The end of the movable inclined rod 23 away from the first power rod 10 abuts against the crossbar provided on the inner wall of the air inlet pipe 4. The movable spring 24 is in a horizontal state until the push pinion 25 moves to the first protruding transition part 26b.

[0040] In the second state, the push pinion 25 meshes with the first protruding transition portion 26b, and the rotation of the push pinion 25 drives the movable inclined rod 23 to swing around the axis of the first power rod 10 until the axis of the movable inclined rod 23 and the axis of the movable spring 24 are on the same straight line.

[0041] In the third state, the push pinion 25 moves to the smooth part 26d, and the shelf 2 falls back under the action of gravity until the push pinion 25 meshes with the second protruding transition part 26c. Since the side of the shelf 2 away from the driven shaft 13 has a set distance from the inner wall of the box 1, the shelf can swing a certain distance toward the inner wall of the box 1. Only then can the rotation of the push pinion 25 drive it to return to the first state. In this way, the swinging of the shelf 2 is realized through the cooperation of the above structure.

[0042] This invention provides a method for drying an optical spherical lens, comprising the following steps: placing the optical spherical lens to be dried in the frame 3 of the drying system, then placing the frame 3 on the shelf 2 of the drying system, then turning on the power supply, and the drying system begins to operate for drying.
