Description

Technical Field

[0001] The present invention relates to the technical field of optical lens processing, and in particular to an automatic detection device and method for optical lenses. Background Art

[0002] Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles, and then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to eventually become optical lens blanks; During the processing of optical lenses, the optical lenses to be inspected are placed on a workbench, and the generated fluorescence is observed under the irradiation of an ultraviolet lamp to complete the inspection of the optical lenses. The overall operation is simple and the intelligence is high. However, in the actual inspection process, the optical lenses are mainly moved to the outside of the ultraviolet lamp manually. When the inspection is performed by manual hand-held method, there will be certain irradiation blind spots, which will lead to certain errors in the inspection results. Moreover, when multiple optical lenses are inspected by manual hand-held method, the optical lenses cannot be kept in the same position each time, which leads to large errors when comparing the experimental results of multiple optical lenses. Moreover, when the inspection is performed by ultraviolet irradiation, only the purity, transparency, uniformity, refractive index and dispersion rate of the optical lenses can be detected. There is no inspection of the quality of the optical lenses, and the inspection effect is relatively simple. Therefore, an automatic inspection device and method for optical lenses are provided.

[0008] Preferably, a rubber sleeve is fixedly sleeved on the outer side of the rotating cylinder.

[0009] Preferably, the outer surfaces of the knocking plate and the second threaded rod are both smooth.

[0010] Preferably, sliding grooves are formed on both sides of the cavity, and the first connecting rod slides through the sliding grooves.

[0011] A method for automatically detecting an optical lens device comprises the following steps: S1.

Turn off the motor and ultraviolet lamp and remove the optical lens.

[0012] The beneficial effects of the present invention are: 1. First, when the optical lens needs to be tested, the optical lens is placed on the round table, the motor is started, and the second threaded rod is driven to move, and the second threaded rod is used to complete the clamping and fixing operation of the optical lens. While the fixing effect is good, the obstruction to the normal irradiation of the ultraviolet lamp is reduced, so that the normal test results can be maintained; 2. Moreover, when the second threaded rod and the optical lens are against each other, the second threaded rod and the moving cylinder will move downward relative to the optical lens as a whole.

Then, when the optical lens is tested, the striking plate will move back and forth, and the striking plate and the optical lens will be knocked against each other to form a knocking operation on the optical lens. If the quality of the optical lens is poor, the refractive index and dispersion rate of the optical lens will change greatly after the knocking. If there is no change or the change is very small, it means that the quality of the optical lens is good, and the quality inspection operation of the optical lens can be completed; 4. Finally, when the optical lens needs to be inspected and automatic adjustment is required, the fifth connecting rod can be rotated to move the fifth connecting rod between two adjacent baffles. During the rotation of the fourth connecting rod, the fourth connecting rod will drive the transmission ring to rotate through the fourth spring, and the rotating ring will drive the rotating cylinder to rotate through the baffle and the fifth connecting rod. The rotating cylinder and the optical lens will resist each other, causing the optical lens to rotate. During this process, if the refractive index and dispersion rate of the optical lens change significantly, it also means that the optical lens has major quality problems and needs to be processed accordingly to improve the detection effect of the optical lens.

DETAILED DESCRIPTION

[0015] See also Figure 1-Figure 13 , an automatic optical lens inspection device, comprising a workbench 1, a plurality of brackets 2 are fixedly connected to the upper side of the workbench 1, an ultraviolet irradiation lamp 3 is fixedly installed on the outer side of each bracket 2, and a round table 4 is fixedly installed on the upper side of the workbench 1; When the optical lens needs to be inspected, the optical lens is placed on the truncated table 4, the ultraviolet irradiation lamp 3 is started, and the refractive index, dispersion rate, etc. of the optical lens are measured, thereby completing the inspection operation of the optical lens. The above are all existing technologies and no redundant description is given; like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , a clamping assembly is installed on the truncated table 4, and the clamping assembly includes a plurality of through grooves 5 uniformly opened on the upper side of the truncated table 4 in the circumferential direction, each through groove 5 is rotatably connected with a first threaded rod 7, each through groove 5 is also slidably connected with a moving box 6, a threaded plate 11 is slidably connected in the moving box 6, a first spring 15 is fixedly connected between the threaded plate 11 and the moving box 6, the first threaded rod 7 is threadedly penetrated by the threaded plate 11, and two threaded cylinders 19 are rotatably connected in the moving box 6, each threaded cylinder 19 is threadedly connected with a second threaded rod 12, a moving cylinder 13 is slidably connected to the outer sides of the two second threaded rods 12, a second connecting plate 17 is commonly fixedly connected to the lower sides of the two second threaded rods 12, a first gear 18 is fixedly connected to the outer side of the threaded cylinder 19, two first racks 16 are fixedly connected to the side wall of the threaded plate 11, and the first gear 18 is meshed with the first rack 16, and a control assembly for controlling the rotation of the first threaded rod 7 is installed in the truncated table 4; First, when the lens to be inspected is placed on the truncated table 4, the first threaded rod 7 starts to rotate. Since the first threaded rod 7 and the through groove 5 rotate, and the through groove 5, the movable box 6, and the threaded plate 11 are in a sliding connection state, the rotating first threaded rod 7 will drive the threaded plate 11 to move in the direction close to the optical lens. The threaded plate 11 drives the movable box 6 to move in the direction close to the optical lens through the first spring 15 until the two second threaded rods 12 and the optical lens are against each other (since the optical lenses produced are basically circular, although optical lenses of other shapes are seen in practice, that is because in real life, secondary processing is required according to other requirements, such as: frames). Then, after all the second threaded rods 12 are against the optical lenses, the second threaded rods 12 will stop moving due to the obstruction of the optical lenses. However, the first threaded rod 7 is still in a rotating state, so the threaded plate 11 will move relative to the movable box 6. The threaded plate 11 compresses the first spring 15. At this time, Figure 7 Based on the direction, the threaded plate 11 moves leftward relative to the second threaded rod 12, the threaded plate 11 drives the first rack 16 to move leftward, the first rack 16 drives the first gear 18 to rotate clockwise, and the first gear 18 drives the threaded barrel 19 to rotate clockwise. Since the threaded barrel 19 and the moving box 6 are rotatably connected, and the two second threaded rods 12 are commonly fixedly connected with the second connecting plate 17, the clockwise rotating threaded barrel 19 will drive the second threaded rod 12 and the moving barrel 13 to move downward, thereby completing the clamping and fixing effect of the optical lens, and the fixing effect is good.

[0016] like Figure 4 , Fig. 9 The control assembly includes a motor 8 fixedly installed in the truncated table 4, a first bevel gear 9 fixedly installed at the output end of the motor 8, a second bevel gear 10 fixedly connected to the outer side of each first threaded rod 7, the second bevel gear 10 is meshed with the first bevel gear 9, a cavity 36 is opened in the second threaded rod 12, a contact switch 23 is slidably installed in the cavity 36, the contact switch 23 is fixedly connected to the moving cylinder 13 through the first connecting rod 24, a second spring 21 is fixedly installed between the contact switch 23 and the cavity 36, a fixed rod 20 is fixedly installed in the cavity 36, and a pressing plate 22 is fixedly installed on the outer side of the fixed rod 20; First of all, the contact switch 23 is a normally closed switch, that is, in the absence of external force, the contact switch 23 is in a closed state. Multiple contact switches 23 are electrically connected to the control circuit of the motor 8 through wires, and multiple contact switches 23 are in a parallel state, that is, in the initial state, after turning on the power switch of the motor 8, the motor 8 can start working. When all the contact switches 23 are triggered, the motor 8 will be turned off. Then, in the initial state, there is a certain distance between the pressing plate 22 and the contact switch 23. Then, after the optical lens light to be detected is on the truncated table 4, the motor 8 is started. The motor 8 drives all the first threaded rods 7 to rotate through the first bevel gear 9 and the second bevel gear 10. Then, when the second threaded rod 12 and the moving cylinder 13 move downward as a whole relative to the moving box 6, when the moving cylinder 13 and the optical lens are offset, the moving cylinder 13 will stop moving due to the obstruction of the optical lens. However, at this time, the second threaded rod 12 is still in a state of continuing to move downward, so it will cause the moving cylinder 13 to move relative to the second threaded rod 12. The second threaded rod 12 moves upward, and the moving cylinder 13 drives the contact switch 23 to move upward through the first connecting rod 24. The contact switch 23 compresses the second spring 21 until the pressing plate 22 and the contact switch 23 are against each other and the contact switch 23 is triggered. This not only completes the clamping effect of the optical lens, but also because the optical lens is generally a concave lens, under the joint action of multiple moving cylinders 13, the optical lens will be as horizontal as possible, so that the position and state of the optical lens can be kept in the same state each time the optical lens is tested, which is convenient for subsequent data comparison and analysis. Moreover, after all the contact switches 23 are triggered, it means that the optical lens has been clamped and fixed, so the motor 8 will be turned off, and the first threaded rod 7 loses the power to rotate, so it will not continue to apply pressure to the clamped optical lens, thereby reducing the force on the optical lens, and will not cause greater damage to the optical lens being tested. The motor 8 can be automatically turned off without manual adjustment, and the degree of automation and intelligence is high.

[0017] like Fig.10 , Fig.11 , Fig.12, the moving box 6 is equipped with a knocking assembly, which includes a second connecting rod 26 that rotates and passes through the moving box 6, a third gear 27 is fixedly connected to the outer side of the second connecting rod 26, a second gear 25 is fixedly connected to the outer side of one of the threaded cylinders 19, the second gear 25 and the third gear 27 are meshed, a fourth connecting rod 33 is fixedly connected to the upper side of the second connecting rod 26, a cam 34 is fixedly connected to the outer side of the fourth connecting rod 33, a third connecting plate 28 is fixedly installed on the upper side of the moving box 6, a third connecting rod 29 is slidably connected to the side wall of the third connecting plate 28, a first connecting plate 14 is fixedly connected to the side wall of the third connecting rod 29, a third spring 32 is fixedly connected between the first connecting plate 14 and the third connecting plate 28, two knocking plates 30 are fixedly connected to the side wall of the first connecting plate 14, the outer surfaces of the knocking plate 30 and the second threaded rod 12 are both smoothly set, and sliding grooves are opened on both sides of the cavity 36, the first connecting rod 24 slides through the sliding groove to determine and limit the movement trajectory of the first connecting rod 24 relative to the second threaded rod 12; First, the two knocking plates 30 are symmetrically arranged on both sides of the fourth connecting rod 33, and one side of the two knocking plates 30 is set as a smooth arc. Then, during the rotation of the threaded cylinder 19, the threaded cylinder 19 will drive the second connecting rod 26 to rotate through the second gear 25 and the third gear 27, the second connecting rod 26 drives the fourth connecting rod 33 to rotate, and the fourth connecting rod 33 drives the cam 34 to rotate. Since the first connecting plate 14 is always against the cam 34, under the action of the cam 34 and the third spring 32, the first connecting plate 14 is connected to the cam 34. Fig.10 Based on the direction, the first connecting plate 14 will move back and forth, and the first connecting plate 14 will drive the knocking plate 30 to move back and forth. The knocking plate 30 and the optical lens will resist each other to form a knocking effect on the optical lens. In the process of detecting the optical lens, if the quality of the optical lens is poor, the refractive index and dispersion rate of the optical lens will change greatly after knocking. If there is no change or the change is very small, it means that the quality of the optical lens is good, and the quality inspection operation of the optical lens can be completed.

[0018] like Fig.13 The outer side of the fourth connecting rod 33 is sleeved with a rotating cylinder 31, and the inner wall of the rotating cylinder 31 is rotatably connected with a transmission ring 37. A plurality of baffles 38 are fixedly installed on the outer circumference of the transmission ring 37. A fifth connecting rod 39 is threadedly connected to the side wall of the rotating cylinder 31. A plurality of fourth springs 35 are fixedly installed between the transmission ring 37 and the fourth connecting rod 33. A rubber sleeve is fixedly sleeved on the outer side of the rotating cylinder 31 to increase the friction of the rotating cylinder 31, thereby enabling the optical lens to rotate. First, when the optical lens is clamped, before the optical lens is abutted against the second threaded rod 12, the optical lens will first abut against the rotating cylinder 31 and the transmission ring 37, thereby causing the fourth spring 35 to deform. Then, before starting the detection operation, according to actual work needs, if the optical lens to be detected is to be rotated, one or more of the fifth connecting rods 39 are rotated to move the fifth connecting rod 39 between two adjacent baffles 38. During the rotation of the fourth connecting rod 33, the fourth connecting rod 33 will drive the transmission ring 37 to rotate through the fourth spring 35, and the transmission ring 37 will drive the baffle 38 to move. When the baffle 38 and the fifth connecting rod 39 abut against each other, it will drive The rotating cylinder 31 rotates, and since the rotating cylinder 31 and the optical lens are against each other, the optical lens will rotate, and then the optical lens can be automatically adjusted. During this process, if the refractive index and dispersion rate of the optical lens change significantly, it also means that the optical lens has a major quality problem and needs to be processed accordingly. If the optical lens to be detected does not need to rotate, the fifth connecting rod 39 does not need to be rotated. During the rotation of the fourth connecting rod 33, the fourth connecting rod 33 will drive the transmission ring 37 to rotate through the fourth spring 35. However, since the transmission ring 37 and the rotating cylinder 31 are rotationally connected, the rotating transmission ring 37 will not drive the rotating cylinder 31 to rotate at this time.

[0019] In addition, protective covers are sleeved on the outer sides of the second threaded rod 12 and the striking plate 30, so when the optical lens is clamped by the second threaded rod 12 or struck by the striking plate 30, no significant damage will be caused to the optical lens.

[0020] A method for automatically detecting an optical lens device comprises the following steps: S1. Place the optical lens to be tested on the round table 4; S2, start the ultraviolet irradiation lamp 3; S3, starting the motor 8, completing the clamping operation of the optical lens, and performing the knocking operation on the optical lens, and at the same time, the optical lens can be rotated; S4, read experimental data; S5, turn off the motor 8 and the ultraviolet irradiation lamp 3, and remove the optical lens.

[0021] In the present invention, when it is necessary to perform a detection operation on the optical lens, the optical lens is placed on the truncated table 4, the ultraviolet irradiation lamp 3 is started, and the refractive index, dispersion rate, etc. of the optical lens are measured, thereby completing the detection operation on the optical lens. The above are all prior arts and no redundant description is given; After the optical lens to be detected is on the truncated table 4, the motor 8 is started. The motor 8 drives all the first threaded rods 7 to rotate through the first bevel gear 9 and the second bevel gear 10. The rotating first threaded rods 7 will drive the threaded plate 11 to move toward the direction close to the optical lens. The threaded plate 11 drives the moving box 6 to move toward the direction close to the optical lens through the first spring 15 until the two second threaded rods 12 and the optical lens are against each other. Then, after all the second threaded rods 12 are against the optical lens, the second threaded rods 12 will stop moving due to the obstruction of the optical lens. However, the first threaded rods 7 are still in a rotating state, so the threaded plate 11 will move relative to the moving box 6. The threaded plate 11 compresses the first spring 15. At this time, Figure 7 Based on the direction, the threaded plate 11 moves leftward relative to the second threaded rod 12, the threaded plate 11 drives the first rack 16 to move leftward, the first rack 16 drives the first gear 18 to rotate clockwise, and the first gear 18 drives the threaded barrel 19 to rotate clockwise. Since the threaded barrel 19 and the moving box 6 are rotatably connected, and the two second threaded rods 12 are commonly fixedly connected with the second connecting plate 17, the clockwise rotating threaded barrel 19 will drive the second threaded rod 12 and the moving barrel 13 to move downward, thereby completing the clamping and fixing effect of the optical lens, and the fixing effect is good; When the second threaded rod 12 and the moving cylinder 13 move downward relative to the moving box 6 as a whole, after the moving cylinder 13 and the optical lens are against each other, the moving cylinder 13 will stop moving due to the obstruction of the optical lens. However, at this time, the second threaded rod 12 is still in a state of continuing to move downward, so the moving cylinder 13 will move upward relative to the second threaded rod 12. The moving cylinder 13 drives the contact switch 23 to move upward through the first connecting rod 24, and the contact switch 23 compresses the second spring 21 until the pressing plate 22 and the contact switch 23 are against each other and the contact switch 23 is triggered. This can not only achieve the clamping effect of the optical lens, but also can achieve the effect of clamping the optical lens. Since the optical lens is generally a concave lens, in multiple moving Under the joint action of the cylinder 13, the optical lens will be in a horizontal state as much as possible, so that the position and state of the optical lens can be kept in the same state each time the optical lens is tested, which is convenient for comparison and analysis of subsequent data. Moreover, after all contact switches 23 are triggered, it means that the optical lens has been clamped and fixed, so the motor 8 will be turned off, and the first threaded rod 7 loses the power to rotate, so it will not continue to apply pressure to the clamped optical lens, thereby reducing the force on the optical lens and causing no greater damage to the optical lens being tested. The motor 8 can be automatically turned off without manual adjustment, and the degree of automation and intelligence is high. During the rotation of the threaded barrel 19, the threaded barrel 19 drives the second connecting rod 26 to rotate through the second gear 25 and the third gear 27, the second connecting rod 26 drives the fourth connecting rod 33 to rotate, and the fourth connecting rod 33 drives the cam 34 to rotate. Since the first connecting plate 14 is always against the cam 34, under the action of the cam 34 and the third spring 32, the first connecting plate 14 is rotated. Fig.10 Based on the direction, the first connecting plate 14 will move back and forth, and the first connecting plate 14 will drive the knocking plate 30 to move back and forth. The knocking plate 30 and the optical lens will form a knocking effect on the optical lens. In the process of testing the optical lens, if the quality of the optical lens is poor, the refractive index and dispersion rate of the optical lens will change greatly after knocking. If there is no change or the change is very small, it means that the quality of the optical lens is good, and then the quality inspection operation of the optical lens can be completed; When the optical lens is clamped, before the optical lens abuts against the second threaded rod 12, the optical lens will first abut against the rotating cylinder 31 and the transmission ring 37, thereby causing the fourth spring 35 to deform. Then, before starting the detection operation, according to actual work needs, if the optical lens to be detected is to be rotated, one or more of the fifth connecting rods 39 are rotated to move the fifth connecting rod 39 between two adjacent baffles 38. During the rotation of the fourth connecting rod 33, the fourth connecting rod 33 will drive the transmission ring 37 to rotate through the fourth spring 35, and the transmission ring 37 will drive the baffle 38 to move. When the baffle 38 and the fifth connecting rod 39 abut against each other, it will drive the rotation. The cylinder 31 rotates, and since the rotating cylinder 31 and the optical lens are against each other, the optical lens will rotate, and then the optical lens can be automatically adjusted. During this process, if the refractive index and dispersion rate of the optical lens change significantly, it also means that the optical lens has a major quality problem and needs to be processed accordingly. If the optical lens to be detected does not need to rotate, the fifth connecting rod 39 does not need to be rotated. During the rotation of the fourth connecting rod 33, the fourth connecting rod 33 will drive the transmission ring 37 to rotate through the fourth spring 35. However, since the transmission ring 37 and the rotating cylinder 31 are rotationally connected, the rotating transmission ring 37 will not drive the rotating cylinder 31 to rotate at this time.
