Description

Technical Field

[0001] The present invention relates to the technical field of lens defect detection, and specifically relates to an intelligent lens defect detection system and a detection method. Background Art

[0002] Lenses include concave lenses and convex lenses. During production or use, it is necessary to detect them. The main purpose of the detection is to discover various defects that may occur during the manufacturing or use of the lenses. These defects may affect the optical performance and use effect of the lenses. The common detection method is the light irradiation method, which requires applying a fluorescent liquid to the lens surface.

[0003] Since the fluorescent liquid can penetrate into fine cracks or defects and produce a consistent and clear fluorescence reaction under ultraviolet light irradiation, so as to detect whether there are defects such as cracks; the existing method is to manually apply the fluorescent liquid to the lens with a brush. However, this method not only cannot ensure whether the entire area of the lens is coated; but also due to the automatic downward fall of the liquid, the thickness of the liquid coating is inconsistent; the thickness of the coating is not easy to control. If the coating is too thick, the excess liquid will affect the detection effect; if the coating is too thin, the cracks at that place will not be penetrated by the fluorescent liquid, which will also lead to the detection effect. Summary of the Invention

During the rotation of the push rod, the piston rod is extruded to move. By extending the telescopic pipe, the transmission disc drives the second rotating sleeve to rotate.

[0016] Further, an unlocking component is arranged on the second rotating sleeve. The unlocking component includes a pulling disc rotatably connected to the side end of the transmission disc. The end of the telescopic rod is fixedly connected to the pulling disc. The side end of the pulling plate is fixedly connected to the first rotating sleeve.

[0024] In the above technical solution, the beneficial effects of the intelligent detection system for lens defects provided by the present invention are as follows:

[0025] By setting a V-shaped application brush and making it rotate forward and backward once each, it is possible to uniformly apply the entire area of the concave lens, and at the same time, it is not easy to overflow the chemical liquid. By passively making the driving rod drive the second rotating sleeve to rotate, the liquid scraping hopper rotates one circle to scrape off and recycle the excess liquid, ensuring that the thickness of the fluorescent liquid on the surface of the concave lens is consistent and can be controlled to the optimal thickness of the fluorescent liquid. The structure is ingenious and can be used repeatedly for multiple times.

Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0042] Embodiment 1: Please refer to Figures 1 - 2 , an intelligent lens defect detection system, including a workbench 1, on which a concave lens 2 is provided, a pair of clamping plates 3 are provided on the workbench 1, a liquid pouring component 4 is provided on the workbench 1, and the liquid pouring component 4 is responsible for pouring chemical liquid onto the surface of the concave lens 2; a smearing component 5 is provided on the workbench 1, and the smearing component 5 includes a smear brush 51; a driving component 6 is provided on the smearing component 5, and the driving component 6 is responsible for driving the smear brush 51 forward and backward to smear the chemical liquid over the entire area of the concave lens 2 surface; a liquid scraping component 7 is further provided on the workbench 1, and the liquid scraping component 7 includes a liquid scraping hopper 71 in an arc structure, and the liquid scraping component 7 is used to drive the liquid scraping hopper 71 to rotate to make the thickness of the chemical liquid on the surface of the concave lens 2 uniform and recycle the excess liquid; an optical detection component 8 is provided on the workbench 1.

[0043] This case is suitable for batch detection of the same batch of concave lenses 2. When performing light detection, it is necessary to first find the liquid scraping hopper 71 suitable for this concave lens 2, or a suitable mold can also be made according to the concave lens 2.

[0044] Specifically, an ultraviolet irradiation lamp 83 and a light-shielding cover 84 are provided on the workbench 1, an adjusting column 81 is fixedly connected to the workbench 1, an adjusting disk 82 is rotatably connected to the adjusting column 81, and the ultraviolet irradiation lamp 83 is detachably connected to the adjusting disk 82. A laser lamp can also be installed later to test light refraction. The chemical liquid is a fluorescent liquid, and uniform smearing can enable the fluorescent liquid to penetrate into fine cracks or defects and produce a consistent and clear fluorescence reaction under ultraviolet light irradiation, so as to detect whether there are defects such as cracks.

[0045] In this case, the fluorescent liquid is first poured onto the concave lens 2, and through the forward rotation of the smear brush 51, the fluorescent liquid is evenly smeared on the left half area of the concave lens 2. Then, the fluorescent liquid is poured again, and the smear brush 51 is rotated in the reverse direction to evenly smear the right half area of the concave lens 2 again, so that each area of the concave lens 2 can be smeared.

[0046] Furthermore, the smear brush 51 can be set in a V shape with an included angle of 120 - 170 degrees, and the best is 150 degrees, which can make the smearing more comprehensive and avoid the overflow of the fluorescent liquid.

[0047] In a further embodiment provided by the present invention, the coating member 5 further includes a support plate 52 fixedly connected to the bottom of the coating brush 51. A telescopic rod 53 is fixedly connected to the bottom of the support plate 52, and a counterweight is arranged inside the support plate 52.

[0048] In order to make the coating brush 51 slightly closer to the surface of the concave lens 2, a telescopic rod 53 can be provided. When the telescopic rod 53 rotates to the bottom, it is in an extended state. When the telescopic rod 53 rotates to the top, under the pressure of the counterweight, it contracts, so that there is no movement interference in the rotation range of the top periphery of the coating brush 51; and the fluorescent liquid can be coated thinner.

[0049] According to actual needs, the telescopic rod 53 can also be set as an ordinary support rod, but in this case, the fluorescent liquid needs to be coated thicker.

[0050] Please refer to Figure 2 and Figure 4 In a further embodiment provided by the present invention, the driving member 6 includes a support platform 61 fixedly connected to the top of the clamping plate 3. A reciprocating driving column 62 is arranged on the support platform 61. A pair of threaded grooves 63 are provided on the reciprocating driving column 62, and the pair of threaded grooves 63 are symmetrically distributed. A driving rod 64 is arranged inside the reciprocating driving column 62. The outer end of the driving rod 64 is movably sleeved with a first rotating sleeve 65. The outer end of the first rotating sleeve 65 is slidably connected to the bottom of the telescopic rod 53. An arc-shaped ramp piece 66 is fixedly connected to the first rotating sleeve 65. A slider 67 is slidably connected in the threaded groove 63. A top rod 68 is arranged at the side end of the slider 67. During each reciprocating movement of the top rod 68, the first rotating sleeve 65 is driven to rotate forward and backward once.

[0051] Specifically, a reduction motor 69 is arranged at the side end of the driving rod 64. The reduction motor 69 is adjusted to a slow state. The slider 67 is movably embedded in the threaded groove 63. The side end of the slider 67 is movably connected to the top rod 68. A guiding hole is provided on the support platform 61, and the top rod 68 slides inside the guiding hole.

[0052] During the rotation of the reduction motor 69, the reciprocating driving column 62 is driven to rotate, so that the top rod 68 starts to move and squeezes the arc-shaped ramp piece 66. Using the slope, the first rotating sleeve 65 starts to rotate. By designing the included angle of the arc-shaped ramp piece 66, for example, 180 - 240 degrees, taking 180 degrees as an example in this case, the coating brush 51 just rotates from the initial position to the left end of the concave lens 2, and the left half area of the concave lens 2 is coated in the whole area.

[0053] A fixed plate (adopting a telescopic structure) is also fixedly connected to the support platform 61. An elastic member (such as an "elastic rope") is fixedly connected to the side end of the fixed plate. The end of the elastic member is fixedly connected to the telescopic rod 53. When the telescopic rod 53 rotates forward by 180 degrees, it will squeeze the elastic member. At this time, the slider 67 enters the second thread groove 63. Under the action of the elastic member, the first rotating sleeve 65 rotates in the reverse direction. Due to the presence of the thread groove 63, the rotation speed is stable and it slowly rotates back to the initial position, and the right area is smeared with fluorescent liquid.

[0054] Please refer to Figure 3 , the liquid pouring component 4 includes a liquid storage cylinder 41. A liquid outlet pipe 42 is arranged at the bottom of the liquid storage cylinder 41. An induction member 43 is arranged at the outer end of the liquid storage cylinder 41. The induction member 43 is responsible for helping the liquid outlet pipe 42 drain liquid at a set time.

[0055] To avoid the overflow of the fluorescent liquid, the fluorescent liquid is discharged in two times, and each time a general area is smeared.

[0056] Specifically, the induction member is an infrared sensor. The infrared sensor is electrically connected to the controller. A pair of infrared sensors are arranged, one on the right side of the liquid storage cylinder 41 and one on the left side of the liquid storage cylinder 41. An electromagnetic valve is arranged inside the liquid outlet pipe 42. When the infrared sensor on the right side is blocked, the electromagnetic valve is triggered to open and a set amount is discharged. When the infrared sensor on the left side is blocked a second time, the electromagnetic valve is triggered to open. At this time, the smearing brush 51 comes to the left side of the concave lens 2. When it rotates in the reverse direction again, the electromagnetic valve will be triggered to open a second time, and a certain amount of fluorescent liquid is discharged and smeared on the right side area of the concave lens 2, and finally the all-round liquid smearing is completed.

[0057] In the embodiment provided by the present invention, the liquid scraping component 7 further includes a rotating rod 72 fixedly connected to the bottom of the liquid scraping hopper 71. The outer end of the driving rod 64 is rotatably sleeved with a second rotating sleeve 73.

[0058] Please refer to Figure 5 , Figure 6 , a transmission component 9 is arranged on the liquid scraping component 7. The transmission component 9 includes a hollow cylinder 91. A piston rod 92 is slidably connected to the inner wall of the hollow cylinder 91. A push rod 93 is fixedly connected to the outer end of the first rotating sleeve 65. An air outlet pipe 94 is fixedly connected to the outer end of the hollow cylinder 91. One end of the air outlet pipe 94 is fixedly connected to a telescopic pipe 95. The outer end of the driving rod 64 is fixedly sleeved with a transmission disc 96. A transmission column is fixedly connected to the side end of the transmission disc 96. The transmission column is made of an elastic metal material and can be appropriately contracted (or can be directly set as a telescopic structure). A transmission hole 97 is opened at the side end of the second rotating sleeve 73. During the rotation of the push rod 93, the piston rod 92 is squeezed to move, and the telescopic pipe 95 is extended to make the transmission disc 96 drive the second rotating sleeve 73 to rotate.

[0059] Specifically, when the first rotating sleeve 65 rotates twice, it will also drive the push rod 93 to rotate twice. When it touches and presses the piston rod 92, the piston rod 92 is extruded, and the gas in the hollow cylinder 91 is transported through the air outlet pipe 94 into the telescopic pipe 95, causing the telescopic pipe 95 to extend and push open the transmission disc 96. The transmission column on the transmission disc 96 is inserted into the transmission hole 97. At this time, the driving rod 64 will drive the second rotating sleeve 73 to rotate, causing the liquid scraping hopper 71 to rotate one circle, scraping and recycling the excess liquid, so that the thickness of the fluorescent liquid on the surface of the concave lens 2 is consistent.

[0060] The coating thickness of the fluorescent liquid needs to be moderate, neither too thin nor too thick. A too thin coating may cause the liquid to not fully penetrate into the cracks, affecting the subsequent detection effect. A too thick coating may block or affect the irradiation effect of ultraviolet light, resulting in an unclear fluorescent effect of cracks or defects, or even making them invisible.

[0061] Moreover, due to the slow rotation of the liquid scraping hopper 71, when scraping the liquid, with its own support, it can effectively prevent the liquid from sliding down to the low point, resulting in excessive thickness at the bottom. (Even if the liquid has already remained at the bottom, the excess liquid will be scraped off to avoid liquid blockage.)

[0062] In a further solution provided by the present invention, an unlocking component 10 is provided on the second rotating sleeve 73. The unlocking component 10 includes a pulling disc 101 rotatably connected to the side end of the transmission disc 96. The end of the telescopic rod 53 is fixedly connected to the pulling disc 101. The side end of the pulling plate is fixedly connected to the first rotating sleeve 65. When the telescopic pipe 95 extends, the driving arc ramp piece 66 is separated from the ejector rod 68. A one-way valve is provided inside the air outlet pipe 94, and a control valve is provided outside.

[0063] In the present invention, when the telescopic rod 53 extends, it not only pushes the transmission disc 96 but also pushes the pulling disc 101, causing the pulling disc 101 to drive the first rotating sleeve 65 to move, separating the driving arc ramp piece 66 from the ejector rod 68. At this time, the coating brush 51 stops rotating, while the liquid scraping hopper 71 starts rotating, achieving the purpose of automatic switching.

[0064] After multiple times of liquid scraping are completed, the control valve is opened (either manually or electrically), the gas inside the air outlet pipe 94 is released, the telescopic pipe 95 contracts, and the transmission disc 96 and the pulling disc 101 return to their initial positions. At this time, the ejector rod 68 can press the arc ramp piece 66, and so on.

[0065] Please refer to Figure 7 and Figure 8, specifically, a limiting annular groove is formed inside the first rotating sleeve 65, a plurality of annularly distributed grooves are formed on the driving rod 64, elastic telescopic blocks are arranged in the grooves, an arc-shaped block is fixedly connected to the top of the elastic telescopic block, and a traction rope is fixedly connected between the side end of the pulling plate 101 and the bottom of the arc-shaped block. When the pulling plate 101 moves, the traction rope can be easily pulled, so that the arc-shaped block retracts into the groove, and the first rotating sleeve 65 is disengaged, facilitating the separation of the arc-shaped ramp piece 66 from the ejector rod 68.

[0066] Please refer to Figure 9 , a backflow prevention component 11 is arranged in the liquid scraping hopper 71. The backflow prevention component 11 includes a rotating shaft 112 rotatably connected to the inner wall of the liquid scraping hopper 71. A check valve plate 113 is fixedly connected to the outer end of the rotating shaft 112. A limiting plate 114 is fixedly connected to the inner wall of the liquid scraping hopper 71. An arc-shaped elastic sheet 111 is also arranged in the liquid scraping hopper 71, and the arc-shaped elastic sheet 111 can only bend inward.

[0067] When the amount of liquid to be scraped is small, the backflow prevention component 11 can be set.

[0068] When the liquid enters the liquid scraping hopper 71, the check valve plate 113 is squeezed under the action of gravity, and the check valve plate 113 rotates inward, and the liquid smoothly enters the chamber between the check valve plate 113 and the liquid scraping hopper 71, and the subsequent rotation of the check valve will be restricted by the limiting plate 114.

[0069] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that the following technical features are replaced or added: Please refer to Figure 10 , a liquid discharging component 12 is arranged on the liquid scraping hopper 71. The liquid discharging component 12 includes a sliding plate 121 slidably connected to the outer end of the liquid scraping hopper 71. A liquid outlet hole is formed on the liquid scraping hopper 71, and the liquid outlet hole corresponds to the position of the sliding plate 121. A pushing plate 122 is fixedly connected to the side end of the sliding plate 121. An abutting plate 123 is fixedly connected to the outer end of the liquid storage cylinder 41. The end of the abutting plate 123 is made of an elastic material and can contract when the pressure is too high, so that the pushing plate 122 can pass through. A sealing block 124 is fixedly connected to the outer end of the pushing plate 122. The sealing block 124 can not only play a sealing effect when the sliding plate 121 does not move, but also play a limiting purpose when the sliding plate 121 slides to the end point.

[0070] When the amount of liquid to be scraped is large, when the liquid scraping hopper 71 rotates to the right, the pushing plate 122 is blocked by the abutting plate 123, and the sliding plate 121 will be pushed open to pour out the liquid.

[0071] An intelligent detection method for lens defects, using the above-mentioned intelligent detection system for lens defects, includes the following steps

[0072] First, the staff places the concave lens 2 between a pair of clamping plates 3 and fixes it.

[0073] Then turn on the reduction motor 69 to make the coating brush 51 rotate forward and backward once each, completing the coating of the entire area of the surface of the concave lens 2;

[0074] Then the liquid scraping hopper 71 starts to rotate slowly to scrape off the excess chemical liquid, ensuring that the coating thickness of the chemical liquid is consistent;

[0075] Finally, place the above-mentioned concave lens 2 in the light-shielding cover 84, adjust the angle of the ultraviolet lamp multiple times to test whether there are cracks.

[0076] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
