DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Example 1: Please refer to Figure 1-Figure 2A lens defect intelligent detection system includes a workbench 1, a concave lens 2 is arranged on the workbench 1, a pair of clamping plates 3 are arranged on the workbench 1, a liquid pouring component 4 is arranged 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 arranged on the workbench 1, and the smearing component 5 includes a smearing brush 51; a driving component 6 is arranged on the smearing component 5, and the driving component 6 is responsible for driving the smearing brush 51 in a forward and reverse direction so that the chemical liquid is smeared on the surface of the concave lens 2 in the entire area; a liquid scraping component 7 is also arranged on the workbench 1, and the liquid scraping component 7 includes a liquid scraping bucket 71 with an arc structure, and the liquid scraping component 7 is used to drive the liquid scraping bucket 71 to rotate, so that the thickness of the chemical liquid on the surface of the concave lens 2 is consistent, and the excess liquid is recovered; an optical detection component 8 is arranged on the workbench 1.

[0022] This embodiment is suitable for batch testing of the same batch of concave lenses 2. When performing illumination testing, it is necessary to first find out the scraping bucket 71 that is suitable for the concave lenses 2. Alternatively, a suitable mold can be made according to the concave lenses 2.

[0023] Specifically, the workbench 1 is provided with an ultraviolet lamp 83 and a light shield 84, 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 lamp 83 is detachably connected to the adjusting disk 82. A laser lamp can be installed later to test light refraction. The chemical liquid is a fluorescent liquid. Evenly applying it can allow the fluorescent liquid to penetrate into tiny cracks or defects and produce a consistent and clear fluorescent reaction under ultraviolet light, thereby detecting whether there are defects such as cracks.

[0024] In this case, fluorescent liquid is first poured onto the concave lens 2, and the fluorescent liquid is evenly applied to the left half of the concave lens 2 by the forward rotation of the coating brush 51. Then, the fluorescent liquid is poured again, and the coating brush 51 is rotated in the reverse direction to evenly apply the fluorescent liquid to the right half of the concave lens 2 again, so that every area of ​​the concave lens 2 can be coated.

[0025] Furthermore, the smear brush 51 can be set to be V-shaped, with an angle of 120-170 degrees, preferably 150 degrees, which can make the smearing more comprehensive and avoid the overflow of the fluorescent liquid.

[0026] In an embodiment further provided by the present invention, the smearing component 5 also includes a support plate 52 fixedly connected to the bottom of the smearing brush 51, a telescopic rod 53 is fixedly connected to the bottom of the support plate 52, and a counterweight block is arranged inside the support plate 52.

[0027] In order to make the smear brush 51 slightly closer to the surface of the concave lens 2, a telescopic rod 53 can be provided. When the telescopic rod 53 is rotated to the bottom, it is extended. When the telescopic rod 53 is rotated to the top, it contracts under the pressure of the counterweight, so that the top periphery of the smear brush 51 is within the rotation range of the scraper bucket 71, and no motion interference occurs; and the fluorescent liquid can be applied thinner.

[0028] According to actual needs, the telescopic rod 53 can also be set as a common support rod, but in this case the fluorescent liquid needs to be applied thicker.

[0029] See also Figure 2 and Figure 4 In an embodiment further provided by the present invention, the driving component 6 includes a support platform 61 fixedly connected to the top of the clamping plate 3, a reciprocating driving column 62 is provided on the support platform 61, a pair of thread grooves 63 are opened on the reciprocating driving column 62, and the pair of thread grooves 63 are symmetrically distributed. A driving rod 64 is provided inside the reciprocating driving column 62, and the outer end of the driving rod 64 is movably sleeved with a first rotating sleeve 65, and 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, and a slider 67 is slidably connected in the thread groove 63. A push rod 68 is provided on the side end of the slider 67. During each reciprocating motion of the push rod 68, the first rotating sleeve 65 is driven to rotate forward and backward once.

[0030] Specifically, a reduction motor 69 is provided 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 push rod 68, a guide hole is opened on the support platform 61, and the push rod 68 slides inside the guide hole.

[0031] During the rotation of the reduction motor 69, the reciprocating drive column 62 is rotated, so that the push rod 68 starts to move, squeezing the arc-shaped ramp piece 66, and using the slope to make the first rotating sleeve 65 start to rotate. By designing the angle of the arc-shaped ramp piece 66, for example, 180-240 degrees, this case takes 180 degrees as an example, so that the smear brush 51 just rotates from the initial position to the left end of the concave lens 2, and the entire left half area of ​​the concave lens 2 is smeared.

[0032] A fixed plate (adopting a telescopic structure) is also fixedly connected to the support platform 61, and 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 180 degrees in the forward direction, the elastic member is squeezed. 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 opposite direction. Due to the thread groove 63, the rotation speed is stable, and it slowly rotates to the initial position to apply fluorescent liquid to the right area.

[0033] See also 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, and a sensor 43 is arranged at the outer end of the liquid storage cylinder 41. The sensor 43 is responsible for helping the liquid outlet pipe 42 to discharge liquid at a set time.

[0034] To avoid overflow of fluorescent liquid, discharge the fluorescent liquid in two times, applying the general area each time.

[0035] Specifically, the sensing element is an infrared sensor, which is connected to the controller via electrical signals. A pair of infrared sensors are provided, one on the right side of the liquid storage cylinder 41 and the other on the left side of the liquid storage cylinder 41. A solenoid valve is provided inside the liquid outlet pipe 42. When the infrared sensor on the right side is blocked, the solenoid valve is triggered to open and a set amount of liquid is discharged. The solenoid valve is triggered to open only when the infrared sensor on the left side is blocked for the second time. At this time, the smear brush 51 comes to the left side of the concave lens 2. When it rotates in the opposite direction again, the solenoid valve is triggered to open for the second time, and a set amount of fluorescent liquid is discharged, and the liquid is smeared on the right side of the concave lens 2, thereby completing the all-round liquid smearing.

[0036] In the embodiment provided by the present invention, the liquid scraping component 7 further comprises a rotating rod 72 fixedly connected to the bottom of the liquid scraping bucket 71 , and the outer end of the driving rod 64 is rotatably sleeved with a second rotating sleeve 73 .

[0037] See also Figure 5 , Figure 6 The wiper component 7 is provided with a transmission component 9, which includes a hollow cylinder 91. The inner wall of the hollow cylinder 91 is slidably connected with a piston rod 92. The outer end of the first rotating sleeve 65 is fixedly connected with a push rod 93. The outer end of the hollow cylinder 91 is fixedly connected with an air outlet pipe 94. One end of the air outlet pipe 94 is fixedly connected with a telescopic tube 95. The outer end of the drive rod 64 is fixedly sleeved with a transmission disk 96. The side end of the transmission disk 96 is fixedly connected with a transmission column. The transmission column is made of elastic metal material and can be appropriately contracted (it can also be directly set to 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 tube 95 is extended to make the transmission disk 96 rotate with the second rotating sleeve 73.

[0038] Specifically, when the first rotating sleeve 65 rotates twice, it will also rotate twice with the push rod 93. When the push rod touches the piston rod 92, the piston rod 92 is squeezed, and the gas in the hollow cylinder 91 is transported to the telescopic tube 95 through the air outlet pipe 94, so that the telescopic tube 95 is extended, and the transmission disk 96 is pushed open. The transmission column on the transmission disk 96 is inserted into the transmission hole 97. At this time, the driving rod 64 will rotate with the second rotating sleeve 73, so that the scraper bucket 71 rotates one circle, and the excess liquid is scraped and recovered, so that the thickness of the fluorescent liquid on the surface of the concave lens 2 is consistent.

[0039] The thickness of the fluorescent liquid should be kept moderate, neither too thin nor too thick. Too thin a coating may prevent the liquid from fully penetrating into the cracks, affecting the subsequent detection results. Too thick a coating may block or affect the effect of ultraviolet radiation, resulting in unclear or even invisible fluorescent effects of cracks or defects.

[0040] Moreover, since the scraping bucket 71 rotates slowly, it can effectively prevent the liquid from sliding down to the bottom point under its own support during scraping, which would cause the bottom to be too thick. (Even if it has been left at the bottom, the excess liquid will be scraped off to avoid liquid obstruction) In the solution further provided by the present invention, an unlocking component 10 is provided on the second rotating sleeve 73, and the unlocking component 10 includes a pulling disk 101 rotatably connected to the side end of the transmission disk 96, the end of the telescopic rod 53 is fixedly connected to the pulling disk 101, and the side end of the pulling plate is fixedly connected to the first rotating sleeve 65. When the telescopic tube 95 is extended, the arc-shaped ramp piece 66 is driven to separate from the push rod 68, and a one-way valve is provided inside the air outlet pipe 94, and a control valve is provided outside.

[0041] In the present invention, when the telescopic rod 53 is extended, it not only pushes the transmission disk 96, but also pushes the pulling disk 101, so that the pulling disk 101 moves with the first rotating sleeve 65, and drives the arc ramp piece 66 to separate from the top rod 68. At this time, the smear brush 51 no longer rotates, and the scraper bucket 71 starts to rotate, thereby achieving the purpose of automatic switching.

[0042] After the subsequent multiple scraping operations are completed, the control valve is opened (either manually or electrically), the gas inside the air outlet pipe 94 is released, the telescopic tube 95 is contracted, and the transmission disk 96 and the pulling disk 101 return to their initial positions. At this time, the push rod 68 can squeeze the arc-shaped ramp sheet 66, and so on.

[0043] See also Figure 7 and Figure 8 Specifically, a limited annular groove is provided inside the first rotating sleeve 65, and a plurality of grooves distributed in an annular shape are provided on the driving rod 64. An elastic telescopic block is provided in the groove, and an arc block is fixedly connected to the top of the elastic telescopic block. A traction rope is fixedly connected between the side end of the pulling disk 101 and the bottom of the arc block. When the pulling disk 101 moves, the traction rope can be easily pulled to retract the arc block into the groove, so that the first rotating sleeve 65 is disengaged, which is convenient for driving the arc ramp piece 66 to separate from the top rod 68.

[0044] See also Fig. 9 An anti-backflow component 11 is provided in the scraper bucket 71, and the anti-backflow component 11 includes a rotating shaft 112 rotatably connected to the inner wall of the scraper bucket 71, and a check plate 113 is fixedly connected to the outer end of the rotating shaft 112. A limit plate 114 is fixedly connected to the inner wall of the scraper bucket 71. An arc-shaped spring piece 111 is also provided in the scraper bucket 71, and the arc-shaped spring piece 111 can only bend inward.

[0045] When the amount of liquid to be scraped off is small, a backflow prevention component 11 may be provided.

[0046] When the liquid enters the scraper bucket 71 , the non-return plate 113 is squeezed by gravity, and the non-return plate 113 rotates inward, and the liquid smoothly enters the chamber between the non-return plate 113 and the scraper bucket 71 , and the subsequent rotation of the non-return plate will be limited by the limit plate 114 .

[0047] Embodiment 2: Embodiment 2 differs from Embodiment 1 in that the following technical features are replaced or added: Fig.10 The scraper bucket 71 is provided with a discharge component 12, and the discharge component 12 includes a slide plate 121 slidably connected to the outer end of the scraper bucket 71. The scraper bucket 71 is provided with a liquid outlet, and the liquid outlet corresponds to the position of the slide plate 121. The side end of the slide plate 121 is fixedly connected with a push plate 122, and the outer end of the liquid storage cylinder 41 is fixedly connected with a resistance plate 123. The end of the resistance plate 123 is made of elastic material. When the pressure is too large, it can be contracted to allow the push plate 122 to pass. The outer end of the push plate 122 is fixedly connected with a sealing block 124. The sealing block 124 can not only play a sealing effect when the slide plate 121 is not moving, but also play a limiting purpose when the slide plate 121 slides to the end point.

[0048] When the amount of liquid to be scraped off is large, when the scraper bucket 71 rotates to the right, the push plate 122 is blocked by the stop plate 123, and the slide plate 121 is pushed away to pour out the liquid.

[0049] A lens defect intelligent detection method, using the above-mentioned lens defect intelligent detection system, comprises the following steps: First, the staff places the concave lens 2 between a pair of clamping plates 3 and fixes it; Then, the reduction motor 69 is turned on to make the coating brush 51 rotate once in both the forward and reverse directions to complete coating of the entire surface of the concave lens 2; Then the scraper bucket 71 starts to rotate slowly to scrape off the excess chemical liquid to ensure that the chemical liquid is applied with a uniform thickness; Finally, the concave lens 2 is placed in the light shield 84, and the angle of the ultraviolet lamp is adjusted several times to test whether there are cracks.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various 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.
