Description

Technical Field

[0001] This invention relates to the field of optical lens ink coating fixture technology, specifically to an adjustable optical lens ink coating fixture and its usage method. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula. This mixture is melted at high temperature in a platinum crucible and ultrasonically stirred to remove air bubbles. Then, it undergoes a long, slow cooling process to prevent internal stress in the glass block. After cooling, the glass block must be measured with optical instruments to check its purity, transparency, uniformity, refractive index, and dispersion to ensure they meet specifications. Qualified glass blocks are then heated and pressed to form optical lens blanks.

[0003] Traditional optical lens ink coating processes require manual positioning of the lens by the operator. Manual positioning is prone to errors. When the optical lens is rotated for ink coating, the lens may become eccentric and shake, which can lead to deviations in the ink layer thickness. Furthermore, manual handling can easily cause the optical lens to fall and be damaged. Therefore, an adjustable optical lens ink coating fixture and its usage method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable optical lens ink coating fixture and its usage method, in order to solve the problems mentioned in the background art, which require the operator to manually position the lens, resulting in errors.

[0016] The present invention also provides a method for processing a stamping device for reinforcing steel sheets, comprising the following steps:

[0017] S1. Positioning: Place the optical lens to be coated with ink inside a placement slot and between the first and second arc-shaped clamping plates. At this time, the output shaft of the servo motor drives the driven gear to rotate through the drive gear, which in turn drives the rotating drum to rotate. The rotating drum drives the rotating base to rotate 120 degrees through the first U-shaped frame, so that the rotating base drives a guide post to abut against the protruding end of the irregular guide plate. The guide post moves under force, and at this time, the guide post drives the second arc-shaped clamping plate to abut against the outside of the optical lens, thus completing the clamping and positioning of the optical lens.

[0018] S2. Fix the vacuum suction cup and evacuate it to adsorb the optical lens onto the vacuum suction cup. Then, rotate the rotating base 120 degrees again. At this time, one end of a guide post disengages from the protruding end of the irregular guide plate. The first telescopic spring drives a guide post to reset, so that a guide post drives a second arc-shaped clamp to disengage from the outside of the optical lens. Then, the push rod of the electric push rod drives the drive motor on the first slide to move upward, so that the drive motor drives the vacuum suction cup to move upward through the second slide. At the same time, the vacuum suction cup drives the optical lens to move upward. At this time, the optical lens moves out of the placement slot. Then, the output shaft of the drive motor drives the vacuum suction cup to rotate, so that the vacuum suction cup can drive the optical lens to rotate for ink coating processing. After the processing is completed, stop evacuating the vacuum suction cup and the optical lens can be removed.

[0019] S3. Adjustment: When processing circular optical lenses of different sizes, first, rotate the threaded rod in the forward or reverse direction to move the first arc-shaped clamping plate inside the placement groove, thereby adjusting the position of the first arc-shaped clamping plate. Then, rotate the external threaded seat in the reverse direction to disengage it from the internal threaded seat. Next, move the fixed post downwards, disengaging the limiting ring from the internal threaded seat. Simultaneously, the fixed post moves the irregularly shaped guide plate out of the mounting groove. Then, rotate the irregularly shaped guide plate in the reverse direction to disengage it from one end of the fixed post, allowing the irregularly shaped guide plate to be replaced. This allows the guide post to be moved different distances, adjusting the distance between the first and second arc-shaped clamping plates.

[0020] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:

[0021] 1. This invention places the optical lens to be inked inside a placement slot between a first arc-shaped clamping plate and a second arc-shaped clamping plate. At this time, the output shaft of the servo motor drives the driven gear to rotate through the driving gear. The rotating drum drives the rotating base to rotate 120 degrees through the first U-shaped frame. This causes the rotating base to drive a guide post to abut against the protruding end of the irregular guide plate. The guide post moves under force, and at this time, the guide post drives the second arc-shaped clamping plate to abut against the outside of the optical lens, thus completing the clamping and positioning of the optical lens. The operation is simple and quick, and no manual handling of the lens is required, improving the efficiency of inking the optical lens.

[0022] 2. When processing circular optical lenses of different sizes, this invention first moves the first arc-shaped clamping plate inside the placement groove by rotating the threaded rod in either the forward or reverse direction, thereby adjusting the position of the first arc-shaped clamping plate. Then, the external threaded seat is rotated in the reverse direction and disengaged from the internal threaded seat. The fixing post is then moved downward, causing the fixing post to move the irregularly shaped guide plate out of the mounting groove. The irregularly shaped guide plate is then rotated in the reverse direction, causing it to disengage from one end of the fixing post. This allows the irregularly shaped guide plate to be replaced, facilitating the movement of the guide post by different distances and adjusting the distance between the first and second arc-shaped clamping plates. This facilitates the positioning and fixing of optical lenses of different sizes, enabling the processing of optical lenses of different sizes. Attached Figure Description

[0036] The placement assembly enables rapid positioning and fixing of optical lenses. The placement assembly includes a first U-shaped frame 31, a rotating base 32, and three threaded rods 34.

The optical lens to be coated with ink is placed inside a placement slot 33 and located between the first arc-shaped clamping plate 35 and the second arc-shaped clamping plate 39. The guide post 37 moves under force, and at this time, the guide post 37 drives the second arc-shaped clamping plate 39 to abut against the outer side of the optical lens, thus completing the clamping and positioning of the optical lens. Moreover, by rotating the threaded rod 34 in the forward or reverse direction, the threaded rod 34 drives the first arc-shaped clamping plate 35 to move inside the placement slot 33, thereby adjusting the position of the first arc-shaped clamping plate 35. A fixing component is provided at the bottom of the rotating base 32.

[0037] One end of the first telescopic spring 38 is fixedly connected to the outside of the guide post 37, and the other end of the first telescopic spring 38 is fixedly connected to the inside of the mounting groove 36.

The second telescopic spring 310 can provide preload to the threaded rod 34 to prevent the threaded rod 34 from rotating due to vibration. The first telescopic spring 38 and the second telescopic spring 310 are consumable parts and need to be maintained and replaced regularly.

[0038] The positioning assembly includes a fixed post 51, a shaped guide plate 52, and a limiting ring 53. The fixed post 51 extends through the interior of the rotating drum 2. The shaped guide plate 52 is threadedly connected to the inner outer side of the fixed post 51. The limiting ring 53 is fixedly sleeved on the outer bottom of the fixed post 51. An internal threaded seat 54 is fixedly connected to the bottom of the fixed seat 1, located outside the limiting ring 53. An external threaded seat 55 is threadedly connected to the inner side of the internal threaded seat 54, located outside the fixed post 51. One end of the external threaded seat 55 abuts against the bottom of the limiting ring 53. 2. The first U-shaped frame 31 drives the rotating seat 32 to rotate 120 degrees, so that the rotating seat 32 drives a guide post 37 to abut against the protruding end of the irregular guide plate 52. The guide post 37 moves under force. At this time, the guide post 37 drives the second arc-shaped clamp 39 to abut against the outside of the optical lens. A rotating component is provided on the outside of the rotating cylinder 2. One end of the irregular guide plate 52 abuts against the other end of one of the guide posts 37. One of the first telescopic springs 38 is in a compressed state. The first telescopic spring 38 can drive the guide post 37 to return to its original position.

[0039] A rotating assembly is provided for the rotation of the rotating base 32. The rotating assembly includes a driven gear 56, which is fixedly sleeved on the outside of the rotating cylinder 2. A servo motor 57 is installed at the bottom of the fixed base 1. The output shaft of the servo motor 57 passes through the bottom of the fixed base 1 and is fixedly connected to a driving gear 58. The driving gear 58 is meshed with the outside of the driven gear 56. The output shaft of the servo motor 57 drives the driven gear 56 to rotate through the driving gear 58, which in turn drives the rotating cylinder 2 to rotate, thereby driving the rotating base 32 to rotate.

[0040] By setting up a fixing component, the optical lens can be fixed to facilitate the ink coating process of the optical lens. The fixing component includes three vacuum suction cups 42, three second U-shaped brackets 43, and a first slide block 44. The bottom of each of the three placement slots 33 is provided with a groove 41. The three vacuum suction cups 42 are respectively installed inside the three grooves 41. The three second U-shaped brackets 43 are fixedly connected to the bottom of the rotating base 32. The first slide block 44 is slidably connected to the inner side of each of the three second U-shaped brackets 43. The top of the first slide block 44 is fixedly connected to a drive unit. A second slide block 46 is fixedly connected to the top of a motor 45. The second slide block 46 is slidably connected to the inner side of a second U-shaped frame 43. The output shaft of the motor 45 passes through the second slide block 46 and is fixedly connected to one end of the vacuum suction cup 42 extending to the bottom of the rotary base 32. Electric push rods 47 are fixedly connected to the bottom of each of the three second U-shaped frames 43. The push rods of the electric push rods 47 pass through the bottom of the second U-shaped frame 43 and are fixedly connected to the bottom of the first slide block 44. The outer bottom of the vacuum suction cup 42 is located at the bottom of the second U-shaped frame 43. A first electrical slip ring 48 is fixedly sleeved on the inner side of the frame 43. Vacuum is drawn into the vacuum chuck 42, so that the optical lens is adsorbed onto the vacuum chuck 42. Then, the servo motor 57 is started by controlling the switch group, so that the rotary table 32 rotates 120 degrees again. At this time, one end of the guide post 37 disengages from the protruding end of the irregular guide plate 52. The first telescopic spring 38 drives the guide post 37 to reset, so that the guide post 37 drives a second arc-shaped clamp 39 to disengage from the outside of the optical lens. Then, the push rod of the electric push rod 47 drives the drive motor 45 on the first slide 44 to move upward, so that the drive motor 45 drives the vacuum chuck 42 to move upward through the second slide 46. At the same time, the vacuum chuck 42 drives the optical lens to move upward. At this time, the optical lens moves out of the placement slot 33. Then, the output shaft of the drive motor 45 drives the vacuum chuck 42 to rotate, so that the vacuum chuck 42 can drive the optical lens to rotate, so as to facilitate the ink coating process of the optical lens. After the processing is completed, the vacuum chuck 42 is stopped to draw vacuum, and the optical lens can be removed.

[0041] To ensure the proper use of the fixture, a second electrical slip ring 59 is fixedly sleeved on the outer side of the rotating drum 2 above the driven gear 56. The second electrical slip ring 59 is fixedly connected to the top of the fixed base 1 via a bracket. The air tube output end of the first electrical slip ring 48 is connected to the air tube input end of the vacuum suction cup 42, and the air tube output end of the second electrical slip ring 59 is connected to the air tube input end of the first electrical slip ring 48. The electrical output end of the second electrical slip ring 59 is connected to the electrical input ends of the drive motor 45 and the electric push rod 47. Through the setting of the second electrical slip ring 59, when the rotating base 32 rotates, it can ensure the normal power supply of the drive motor 45 and the electric push rod 47, preventing the wire from getting tangled. In addition, the first electrical slip ring 48 can complete the connection of the air tube of the vacuum suction cup 42 and can evacuate the vacuum suction cup 42, thereby completing the fixation of the optical lens.

[0042] Working principle or structural principle: When in use, the optical lens to be coated with ink is placed inside a placement slot 33 and located between the first arc-shaped clamping plate 35 and the second arc-shaped clamping plate 39. At this time, the servo motor 57 is started by controlling the switch group. The output shaft of the servo motor 57 drives the driven gear 56 to rotate through the driving gear 58. The driven gear 56 drives the rotating drum 2 to rotate. The rotating drum 2 drives the rotating seat 32 to rotate 120 degrees through the first U-shaped frame 31. This causes the rotating seat 32 to drive a guide post 37 to abut against the protruding end of the irregular guide plate 52. The guide post 37 moves under force. At this time, the guide post 37 drives the second arc-shaped clamping plate 39 to abut against the outside of the optical lens, thus completing the clamping and positioning of the optical lens. The operation is simple and quick, and no personnel need to manually hold the lens, which improves the efficiency of coating optical lenses with ink.

[0043] Vacuuming is performed on vacuum chuck 42 to adsorb the optical lens onto it. Then, the servo motor 57 is started by controlling the switch group, causing the rotary table 32 to rotate 120 degrees again. At this time, one end of the guide post 37 disengages from the protruding end of the irregular guide plate 52. The first telescopic spring 38 drives the guide post 37 to reset, causing the guide post 37 to drive the second arc-shaped clamp 39 to disengage from the outside of the optical lens. Then, the push rod of the electric push rod 47 is extended by controlling the switch group. The push rod of the electric push rod 47 drives the drive motor 45 on the first slide 44 to move upward. The drive motor 45 drives the vacuum chuck 42 to move upward through the second slide 46. At the same time, the vacuum chuck 42 drives the optical lens to move upward. At this time, the optical lens moves out of the placement slot 33. Then, the drive motor 45 is started by controlling the switch group. The output shaft of the drive motor 45 drives the vacuum chuck 42 to rotate, so that the vacuum chuck 42 can drive the optical lens to rotate, so as to facilitate the ink coating process of the optical lens. After the processing is completed, the vacuuming of vacuum chuck 42 is stopped, and the optical lens can be removed.

[0044] When processing circular optical lenses of different sizes, firstly, by rotating the threaded rod 34 in either the forward or reverse direction, the threaded rod 34 moves the first arc-shaped clamping plate 35 within the placement groove 33, thereby adjusting the position of the first arc-shaped clamping plate 35. Then, by rotating the external threaded seat 55 in the reverse direction, the external threaded seat 55 disengages from the internal threaded seat 54. Next, the fixing post 51 moves downward, and the limiting ring 53 disengages from the internal threaded seat 54. Simultaneously, the fixing post 51 moves the irregularly shaped guide plate 52 out of the mounting groove 36. Then, the irregularly shaped guide plate 52 is rotated in the reverse direction, disengaging from one end of the fixing post 51. This allows the irregularly shaped guide plate 52 to be replaced, facilitating the movement of the guide post 37 by different distances. This design facilitates the positioning and fixing of optical lenses of different sizes, enabling the processing of optical lenses of different sizes. When replacing the irregular guide plate 52, the irregular guide plate 52 is rotated in the forward direction to fix it on the outside of one end of the fixing post 51. Then, the fixing post 51 is pushed to move the irregular guide plate 52 at one end of the fixing post 51 to the inside of the mounting groove 36, and the protruding end of the irregular guide plate 52 abuts against the outside of a guide post 37. At the same time, the limiting ring 53 moves into the inside of the internal thread seat 54. The external thread seat 55 is rotated in the forward direction to screw one end of the external thread seat 55 into the inside of the internal thread seat 54 and fix the limiting ring 53, thus completing the replacement of the irregular guide plate 52.

[0045] The present invention also provides a method for processing a stamping device for reinforcing steel sheets, comprising the following steps:

[0046] S1. Positioning: The optical lens to be coated with ink is placed inside a placement slot 33 and positioned between the first arc-shaped clamping plate 35 and the second arc-shaped clamping plate 39. At this time, the output shaft of the servo motor 57 drives the driven gear 56 to rotate through the drive gear 58. The driven gear 56 then drives the rotating drum 2 to rotate. The rotating drum 2 drives the rotating seat 32 to rotate 120 degrees through the first U-shaped frame 31. This causes the rotating seat 32 to drive a guide post 37 to abut against the protruding end of the irregular guide plate 52. The guide post 37 moves under force. At this time, the guide post 37 drives the second arc-shaped clamping plate 39 to abut against the outside of the optical lens, thus completing the clamping and positioning of the optical lens.

[0047] S2. Fix the vacuum suction cup 42 and evacuate it to adsorb the optical lens onto the vacuum suction cup 42. Then, rotate the rotating base 32 another 120 degrees. At this time, one end of the guide post 37 disengages from the protruding end of the irregular guide plate 52. The first telescopic spring 38 drives the guide post 37 to reset, so that the guide post 37 drives the second arc-shaped clamp 39 to disengage from the outside of the optical lens. Then, the push rod of the electric push rod 47 drives the drive motor 45 on the first slide 44 to move upward, so that the drive motor 45 drives the vacuum suction cup 42 to move upward through the second slide 46. At the same time, the vacuum suction cup 42 drives the optical lens to move upward. At this time, the optical lens moves out of the placement slot 33. Then, the output shaft of the drive motor 45 drives the vacuum suction cup 42 to rotate, so that the vacuum suction cup 42 can drive the optical lens to rotate for ink coating processing. After the processing is completed, stop the vacuum suction cup 42 to evacuate the vacuum, and the optical lens can be removed.

[0048] S3. Adjustment: When processing circular optical lenses of different sizes, first, rotate the threaded rod 34 in the forward or reverse direction to move the first arc-shaped clamping plate 35 inside the placement groove 33, thereby adjusting the position of the first arc-shaped clamping plate 35. Then, rotate the external threaded seat 55 in the reverse direction to disengage it from the internal threaded seat 54. Then, move the fixing post 51 downward to disengage the limiting ring 53 from the internal threaded seat 54. At the same time, the fixing post 51 drives the irregular guide plate 52 to move out of the mounting groove 36. Then, rotate the irregular guide plate 52 in the reverse direction to disengage it from one end of the fixing post 51. The irregular guide plate 52 can then be replaced. This allows the guide post 37 to be moved by different distances, adjusting the distance between the first arc-shaped clamping plate 35 and the second arc-shaped clamping plate 39.

10. A method of using the adjustable optical lens ink coating fixture according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Positioning: Place the optical lens to be coated with ink inside a placement slot (33) and between the first arc-shaped clamp (35) and the second arc-shaped clamp (39). At this time, the output shaft of the servo motor (57) drives the driven gear (56) to rotate through the active gear (58). The driven gear (56) drives the rotating drum (2) to rotate. The rotating drum (2) drives the rotating seat (32) to rotate 120 degrees through the first U-shaped frame (31). This causes the rotating seat (32) to drive a guide post (37) to abut against the protruding end of the irregular guide plate (52). The guide post (37) moves under force. At this time, the guide post (37) drives the second arc-shaped clamp (39) to abut against the outside of the optical lens, thus completing the clamping and positioning of the optical lens. S2. Fix and evacuate the vacuum chuck (42) to adsorb the optical lens onto the vacuum chuck (42). Then, rotate it 120 degrees again via the turntable (32). At this time, one end of a guide post (37) disengages from the protruding end of the irregular guide plate (52). The first telescopic spring (38) drives one guide post (37) to reset, so that one guide post (37) drives a second arc-shaped clamp (39) to disengage from the outside of the optical lens. Then, the push rod of the electric push rod (47) drives the drive electric motor on the first slide (44) to... The machine (45) moves upward, causing the drive motor (45) to drive the vacuum chuck (42) upward through the second slide (46). At the same time, the vacuum chuck (42) drives the optical lens upward. At this time, the optical lens moves out of the placement slot (33). Then, the output shaft of the drive motor (45) drives the vacuum chuck (42) to rotate, so that the vacuum chuck (42) can drive the optical lens to rotate for ink coating processing. After the processing is completed, the vacuum chuck (42) stops evacuating the vacuum, and the optical lens can be removed. S3. Adjustment: When processing circular optical lenses of different sizes, first, rotate the threaded rod (34) in the forward or reverse direction to move the first arc-shaped clamp (35) inside the placement groove (33) to adjust the position of the first arc-shaped clamp (35). Then, rotate the external threaded seat (55) in the reverse direction to disengage the external threaded seat (55) from the interior threaded seat (54). Then, move the fixed post (51) downward to disengage the limiting ring (53) from the interior threaded seat (54). At the same time, the fixed post (51) drives the irregular guide plate (52) to move out of the mounting groove (36). Then, rotate the irregular guide plate (52) in the reverse direction to disengage the irregular guide plate (52) from one end of the fixed post (51). The irregular guide plate (52) can be replaced. The guide post (37) can be moved by different distances to adjust the distance between the first arc-shaped clamp (35) and the second arc-shaped clamp (39).
