Description

Technical Field

[0001] This invention relates to the technical field of lens manufacturing, and more specifically, to an apparatus for manufacturing optical lens gaskets. Background Technology

[0002] Optical lens gaskets are key components in lens assembly, primarily used for precise spacing between lens elements, sealing against dust, and eliminating internal stray light to ensure lens image quality.

[0003] With the development of optical technology, aspherical and meniscus lenses are widely used. Traditional flat washers cannot adapt to the curved edges of lenses, which can easily lead to problems such as unstable contact, lens edge chipping, and optical axis misalignment. Curved or hyperboloid washers have become the mainstream demand. At present, curved washers are mostly made by first stamping flat washer blanks, and then precision turning or injection molding to form the curved surface. Subsequent grinding is the core process to ensure surface accuracy.

[0004] Existing grinding equipment is mostly a single-station structure, requiring manual loading and unloading, and gasket flipping. It has low automation and poor production efficiency. When grinding thin annular gaskets, there is a lack of reliable fixing structure, which makes them prone to radial displacement or deformation, affecting grinding accuracy. At the same time, it is difficult to achieve double-sided differential grinding, and grinding debris is easy to accumulate and scratch the gaskets. Furthermore, the compatibility of gaskets with different curvatures is poor, and the tooling replacement cost is high. Summary of the Invention

[0005] The purpose of this invention is to provide an optical lens gasket production apparatus that can efficiently and simultaneously perform fine grinding on both sides of the gasket.

[0006] This invention is achieved through the following technical solution: The optical lens gasket production apparatus of this invention includes a horizontally arranged operation plate, a support tube vertically arranged on the operation plate, a rotating shaft rotatably arranged in the support tube, a first driving device for driving the rotating shaft to rotate, a second driving device for driving the rotating shaft to move up and down axially, and a plurality of grinding devices distributed along the circumference of the support tube; the grinding device includes a lower support plate connected to the side wall of the support tube, a lower grinding head arranged on the upper side of the lower support plate, a lower electromagnet arranged in the lower grinding head, a third driving device for driving the lower grinding head to rotate, an upper support plate connected to the side wall of the rotating shaft, an upper grinding head arranged on the lower side of the upper support plate, and an upper electromagnet arranged in the upper grinding head; a gasket is sandwiched between the upper grinding head and the lower grinding head; the inner ring of the gasket is detachably connected to a connector, the connector being made of a material that can be attracted by an electromagnet.

[0007] Furthermore, the roughness of the upper grinding head and the lower grinding head on the upper and lower sides of the washer are different.

[0008] Furthermore, the lower support plate has a vertically arranged drive tube at one end near the lower grinding head, and the lower grinding head is sleeved on the drive tube; the lower grinding head is threadedly connected to the drive tube; the connector includes a horizontally arranged connecting ring and a connecting post fixed on the upper side of the connecting ring; the washer is sleeved on the outer ring of the connecting ring, and both the connecting ring and the connecting post are sleeved on the upper outer wall of the drive tube.

[0009] Furthermore, the inner wall of the washer is provided with an annular groove, and the upper edge of the connecting ring is provided with multiple arc-shaped cards; the cards are engaged in the groove, and the cards are connected to the connecting ring by bolts.

[0010] Furthermore, the washer is slidably connected to the outer wall of the connecting ring, and the thickness of the card is less than the width of the card slot.

[0011] Furthermore, a vertically arranged support column is fixedly provided on the upper support plate, and the upper grinding head is sleeved on the lower end of the support column; the upper grinding head has a ring structure and is threadedly connected to the support column; when the upper grinding head and the lower grinding head are respectively attached to both sides of the washer, the connecting column is inserted into the upper grinding head.

[0012] Furthermore, the support column has a through-type first water channel, and the lower grinding head has a through-type second water channel. The first water channel and the second water channel are connected, and the first water channel is connected to a water supply pipe. The drive pipe sidewall has a drain hole, which is located above the lower grinding head, and there is a gap between the drain hole and the connecting column.

[0013] Furthermore, the first driving device includes a drive shaft rotatably disposed in the support tube, a first driven wheel disposed at the lower end of the drive shaft, a first motor fixedly disposed on the lower side of the operation panel, a first driving wheel disposed on the output shaft of the first motor, and a first transmission belt for connecting the first driven wheel and the first driving wheel; the rotating shaft is connected to the drive shaft.

[0014] Furthermore, the upper end of the drive shaft is provided with a vertically arranged limiting hole, and the rotating shaft is slidably disposed in the limiting hole. The cross-section of the limiting hole and the rotating shaft are both hexagonal. The second driving device includes a top plate fixedly disposed on the upper end of the rotating shaft, and a telescopic cylinder vertically fixedly disposed on the outer side wall of the support tube. The movable end of the telescopic cylinder abuts against the lower side wall of the top plate.

[0015] Furthermore, the third driving device includes a second driven wheel fixedly disposed at the lower end of the driving tube, a second motor fixedly disposed on the lower support plate, a second driving wheel disposed on the output shaft of the second motor, and a second transmission belt for connecting the second driven wheel and the second driving wheel.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects: In the optical lens gasket production apparatus of the present invention, the rotating shaft is lifted by a second driving device to separate the upper grinding head from the lower grinding head. Then, the gasket is placed on the lower grinding head. The second driving device lowers the rotating shaft, causing the upper grinding head to descend and press against the gasket. A third driving device drives the lower grinding head to rotate. When the roughness of the upper grinding head is greater than that of the lower grinding head, the friction between the gasket and the upper grinding head is greater. At this time, the relative rotation speed between the lower grinding head and the gasket is faster than that between the upper grinding head and the gasket, thus allowing for more grinding of the lower surface of the gasket. Conversely, it allows for grinding of the upper surface of the gasket. After the gasket has finished grinding in one lower grinding head and one upper grinding head, the lower electromagnet in the lower grinding head is energized to attract the connector and the gasket. Two drive units drive the upper grinding head to rise, then the first drive unit drives the rotating shaft to rotate, causing the upper grinding head to rotate directly above the adjacent lower grinding head. Then the second drive unit drives the upper grinding head to descend and continue grinding. At this time, the roughness of the upper and lower grinding heads on both sides of the washer changes, for example, from upper grinding head > lower grinding head to lower grinding head > upper grinding head, and the roughness of the upper and lower grinding heads generally shows a decreasing trend. The other side of the washer can be ground. After one cycle, the washer can be ground with high precision, so that its surface finish can be used in high-precision environments. The whole process does not require manual switching of the washer position, and there is a washer in the grinding state between each upper and lower grinding head during grinding, so the production efficiency is higher and the degree of automation is higher.

Detailed Implementation

[0019] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 12As shown, the optical lens gasket 30 production apparatus of this embodiment includes a horizontally arranged operation plate 10, a support tube 11 vertically arranged on the operation plate 10, a rotating shaft 12 rotatably arranged in the support tube 11, a first driving device 13 for driving the rotating shaft 12 to rotate, a second driving device 14 for driving the rotating shaft 12 to move up and down axially, and a plurality of grinding devices 20 distributed along the circumferential direction of the support tube 11; the grinding device 20 includes a lower support plate 21 connected to the side wall of the support tube 11, and is arranged on the lower... The support plate 21 has a lower grinding head 22 on its upper side, a lower electromagnet in the lower grinding head 22, a third drive device 23 for driving the lower grinding head 22 to rotate, an upper support plate 24 connected to the side wall of the rotating shaft 12, an upper grinding head 25 on its lower side, and an upper electromagnet in the upper grinding head 25; a washer 30 is sandwiched between the upper grinding head 25 and the lower grinding head 22; the inner ring of the washer 30 is detachably connected to a connector 40, which is made of a material that can be attracted by an electromagnet. Specifically, during use, the second drive device 14 lifts the rotating shaft 12, separating the upper grinding head 25 from the lower grinding head 22. Then, the washer 30 is placed on the lower grinding head 22. The second drive device 14 lowers the rotating shaft 12, causing the upper grinding head 25 to descend and press against the washer 30. The third drive device 23 drives the lower grinding head 22 to rotate. When the roughness of the upper grinding head 25 is greater than that of the lower grinding head 22, the friction between the washer 30 and the upper grinding head 25 is greater. At this time, the relative rotational speed between the lower grinding head 22 and the washer 30 is faster than that between the upper grinding head 25 and the washer 30, thus allowing for more grinding of the lower surface of the washer 30. Conversely, the upper surface of the washer 30 can be ground. After the washer 30 has finished grinding in one lower grinding head 22 and one upper grinding head 25, the lower electromagnet in the lower grinding head 22 is energized to attract the connector 40 and the washer 30. The second drive device 14 then drives the upper grinding head 22 to rotate. The grinding head 25 rises, and then the first drive device 13 drives the rotating shaft 12 to rotate, causing the upper grinding head 25 to rotate directly above the adjacent lower grinding head 22. Then, the second drive device 14 drives the upper grinding head 25 to descend and continue grinding. At this time, the roughness of the upper grinding head 25 and the lower grinding head 22 on both sides of the washer 30 changes, for example, from upper grinding head 25 > lower grinding head 22 to lower grinding head 22 > upper grinding head 25. The roughness of the upper grinding head 25 and the lower grinding head 22 generally shows a decreasing trend, which can grind the other side of the washer 30. After one cycle, the washer 30 can be ground with high precision, so that its surface finish can be used in high-precision application environments. The whole process does not require manual switching of the position of the washer 30. During grinding, there is a washer 30 between each upper grinding head 25 and lower grinding head 22, so the production efficiency is higher and the degree of automation is higher.

[0020] In this embodiment, the roughness of the upper grinding head 25 and the lower grinding head 22 on the upper and lower sides of the washer 30 are different. Specifically, not only are the roughnesses of the grinding heads on the upper and lower sides of the washer 30 different, but the roughnesses of the upper grinding head 25 and the lower grinding head 22 in different grinding devices 20 show a decreasing trend. The upper electromagnet in the upper grinding head 25 and the lower electromagnet in the lower grinding head 22 mainly serve to transfer the washer 30 and the connector 40. When the upper electromagnet is energized, the connector 40 and the washer 30 are attracted by the upper grinding head 25, and then enter the next lower grinding head 22 with the upper grinding head 25; when the lower electromagnet is energized, the connector 40 and the washer 30 are attracted by the lower grinding head 22, at which time the new upper grinding head 25 will abut against the upper side of the washer 30 and grind it. Usually, since each washer 30 needs to circulate a full circle on the operation plate 10 before grinding is completed, a batch of washer 30 can be ground simultaneously. Depending on the different requirements for the surface roughness of the gasket 30, several grinding devices 20 can be set up as a group, so that multiple batches can be ground simultaneously on one operation panel 10.

[0021] In this embodiment, the lower support plate 21 is provided with a vertically arranged drive tube 26 at one end near the lower grinding head 22, and the lower grinding head 22 is sleeved on the drive tube 26; the lower grinding head 22 is threadedly connected to the drive tube 26; the connector 40 includes a horizontally arranged connecting ring 41 and a connecting post 42 fixedly arranged on the upper side of the connecting ring 41; the washer 30 is sleeved on the outer ring of the connecting ring 41, and both the connecting ring 41 and the connecting post 42 are sleeved on the upper outer wall of the drive tube 26. Specifically, the connector 40 serves two purposes: first, to move the washer 30; and second, to limit the washer 30 and prevent it from shifting radially during the grinding process. The lower grinding head 22 is fixed to the drive tube 26, and then the connector 40 is fitted onto the upper end of the drive tube 26. In this way, the lower side of the washer 30 fits against the lower grinding head 22. Since the lower grinding head 22 and the upper grinding head 25 are independent structures, the surface curvature of the lower grinding head 22 (or the upper grinding head 25) can be selected according to the curvature of the lenses on both sides of the washer 30, so that the two sides of the washer 30 can be ground into a suitable shape.

[0022] In this embodiment, the inner wall of the washer 30 is provided with an annular groove 31, and the upper edge of the connecting ring 41 is provided with multiple arc-shaped cards 43; the cards 43 are engaged in the groove 31, and the cards 43 are connected to the connecting ring 41 by bolts. Specifically, since both sides of the washer 30 are ground simultaneously, it cannot be clamped and fixed by the two sides of the washer 30. Therefore, a groove 31 is provided on the inner side of the washer 30. The cards 43 are first inserted into the groove 31, and then the cards 43 are fixed to the connecting ring 41 by bolts.

[0023] In this embodiment, the washer 30 is slidably connected to the outer wall of the connecting ring 41, and the thickness of the card 43 is less than the width of the slot 31. Specifically, the washer 30 contacts the outer side of the connecting ring 41, which can limit the washer 30 and prevent it from having a radial position. Furthermore, since the thickness of the washer 30 will change during the grinding process, the width of the slot 31 needs to be significantly larger than the thickness of the card 43 so that the washer 30 can have a certain amount of axial movement space.

[0024] In this embodiment, a vertically arranged support column 27 is fixedly mounted on the upper support plate 24, and an upper grinding head 25 is sleeved on the lower end of the support column 27. The upper grinding head 25 has a ring-shaped structure and is threadedly connected to the support column 27. When the upper grinding head 25 and the lower grinding head 22 are respectively attached to both sides of the washer 30, the connecting column 42 is inserted into the upper grinding head 25. Specifically, during grinding, the connecting column 42 is inserted into the upper grinding head 25 to limit the position of the upper grinding head 25. In this way, the upper grinding head 25 and the lower grinding head 22 can always be coaxially arranged through the drive tube 26 and the connecting column 42.

[0025] In this embodiment, the support column 27 has a through-type first water channel 271, and the lower grinding head 22 has a through-type second water channel 251. The first water channel 271 and the second water channel 251 are connected, and the first water channel 271 is connected to a water supply pipe 28. The drive pipe 26 has a drain hole 261 on its side wall, which is located above the lower grinding head 22. There is a gap between the drain hole 261 and the connecting column 42. Specifically, a large amount of powder is generated during the grinding process, which needs to be drained away with water in real time. The water supply pipe 28 sends clean water into the first water channel 271 and the second water channel 251, and the water is discharged from the end of the second water channel 251 and flows to the surface of the washer 30. The metal powder is sent into the drive pipe 26 through the drain hole 261 and discharged through the drive pipe 26. Some channels for water flow can be provided on the outside of the connecting ring 41.

[0026] In this embodiment, the first driving device 13 includes a drive shaft 131 rotatably disposed in the support tube 11, a first driven wheel 132 disposed at the lower end of the drive shaft 131, a first motor 133 fixedly disposed on the lower side of the operation plate 10, a first driving wheel disposed on the output shaft of the first motor 133, and a first transmission belt 134 for connecting the first driven wheel 132 and the first driving wheel; the rotating shaft 12 is connected to the drive shaft 131. Specifically, the first motor 133 can drive the first driven wheel 132 and the drive shaft 131 to rotate through the first transmission belt 134, and the drive shaft 131 can drive the rotating shaft 12 to rotate, thereby driving the multiple upper support plates 24 to rotate and adjust their positions. Since precise position control is required, the first motor 133 can be a servo motor. In addition to using the first transmission belt 134 for transmission, gear transmission, sprocket and chain transmission, etc. can also be used.

[0027] In this embodiment, the upper end of the drive shaft 131 is provided with a vertically arranged limiting hole 135, and the rotating shaft 12 is slidably disposed in the limiting hole 135. Both the limiting hole 135 and the rotating shaft 12 have hexagonal cross sections. The second drive device 14 includes a top plate 142 fixedly disposed on the upper end of the rotating shaft 12, and a telescopic cylinder 141 vertically fixedly disposed on the outer side wall of the support tube 11. The movable end of the telescopic cylinder 141 abuts against the lower side wall of the top plate 142. Specifically, since both the limiting hole 135 and the rotating shaft 12 are hexagonal, the drive shaft 131 can drive the rotating shaft 12 to rotate, and the rotating shaft 12 can also move axially. The structure is similar to a telescopic joint. Therefore, the telescopic cylinder 141 can push the top plate 142, pushing the top plate 142, the rotating shaft 12, and multiple upper support plates 24 upward. Since the rotating shaft 12 will rotate again afterward, ball bearings can be provided at the movable end of the telescopic cylinder 141. This reduces the friction between the movable end of the telescopic cylinder 141 and the top plate 142.

[0028] The third drive device 23 in this embodiment includes a second driven wheel 231 fixedly mounted on the lower end of the drive tube 26, a second motor 232 fixedly mounted on the lower support plate 21, a second driving wheel 233 mounted on the output shaft of the second motor 232, and a second transmission belt 234 for connecting the second driven wheel 231 and the second driving wheel 233. Specifically, the second motor 232 can drive the drive tube 26 to rotate via the second transmission belt 234. Alternatively, gear transmission, sprocket and chain transmission, etc., can also be used.

[0029] In summary, the optical lens gasket 30 production apparatus of this embodiment, during use, uses the second drive device 14 to lift the rotating shaft 12, separating the upper grinding head 25 from the lower grinding head 22. Then, the gasket 30 is placed onto the lower grinding head 22. The second drive device 14 then lowers the rotating shaft 12, causing the upper grinding head 25 to descend and press against the gasket 30. The third drive device 23 drives the lower grinding head 22 to rotate. When the roughness of the upper grinding head 25 is greater than that of the lower grinding head 22, the friction between the gasket 30 and the upper grinding head 25 is greater. At this time, the relative rotational speed between the lower grinding head 22 and the gasket 30 is faster than that between the upper grinding head 25 and the gasket 30. Therefore, more of the lower surface of the gasket 30 can be ground, and vice versa, the upper surface of the gasket 30 can be ground. After the gasket 30 has finished grinding in one lower grinding head 22 and one upper grinding head 25, the lower electromagnet in the lower grinding head 22 is energized to attract the connector 40 and the gasket 30. The second drive device 23 then rotates the lower grinding head 30. Device 14 drives the upper grinding head 25 to rise, then the first driving device 13 drives the rotating shaft 12 to rotate, so that the upper grinding head 25 rotates to be directly above the adjacent lower grinding head 22. Then the second driving device 14 drives the upper grinding head 25 to descend and continue grinding. At this time, the roughness of the upper grinding head 25 and the lower grinding head 22 on both sides of the washer 30 changes, for example, from upper grinding head 25 > lower grinding head 22 to lower grinding head 22 > upper grinding head 25. And the roughness of the upper grinding head 25 and the lower grinding head 22 generally shows a decreasing trend, so that the other side of the washer 30 can be ground. After one cycle, the washer 30 can be ground with high precision, so that its surface finish can be used in high-precision application environments. The whole process does not require manual switching of the position of the washer 30. During grinding, there is a washer 30 between each upper grinding head 25 and lower grinding head 22, so the production efficiency is higher and the degree of automation is higher.
