When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0036] like Figures 1 to 12 As shown, the lens inspection equipment of the present invention includes: a turntable 100, a flow line 200 located on one side of the turntable 100, and a loading and unloading station 300, a scribing station 400, a dust removal station 500 and an inspection station 600 arranged sequentially along the rotation direction of the turntable 100.

[0037] A flow fixture 201 is placed on the flow line 200, and the lens is placed inside the flow fixture 201. The flow line 200 drives the flow fixture 201 to move. A fixing fixture 101 is fixedly installed on the turntable 100. The fixing fixture 101 is used to fix the lens. The fixing fixture 101 is provided with a cavity, and the lens is placed inside the cavity.

[0038] The fixing fixture 101 is provided with a fixing component 102, which is located on both sides of the cavity and fixes the lens from both sides. The fixing component 102 includes: a push rod 103, a fixing plate 104, a moving part 105, and a fixing post 106. The fixing plate 104 has a lateral fixing surface 107 and a downward fixing surface 108. The push rod 103 drives the fixing plate 104 to move downward and towards the center. Moving towards the center allows the two fixing plates 104 to work together to clamp the lens, and moving downward allows the downward fixing surface 108 to press and fix the lens.

[0039] In other words, in this application, the lens is fixed by clamping and pressing from both sides.

[0040] In this application, a positioning part 109 is integrally mounted on the moving part 105. The positioning part 109 is provided with a through hole 1010. The pushing rod 103 passes through the through hole 1010. A first spring 1011 is sleeved on the pushing rod 103. A contact part 1012 is integrally connected to the pushing rod 103. One end of the first spring 1011 abuts against the contact part 1012. The first spring 1011 pushes the contact part 1012 to move the pushing rod 103 toward the center.

[0041] The fixed column 106 is provided with a first positioning groove 1013, and the movable part 105 is integrally mounted with a first positioning block 1014. The first positioning block 1014 slides in the first positioning groove 1013. The arrangement of the first positioning groove 1013 and the first positioning block 1014 allows the movable part 105 to slide axially on the fixed column 106.

[0042] A second spring 1018 is sleeved on the fixed column 106. The upper end of the second spring 1018 abuts against the moving part 105. The second spring 1018 is used to push the moving part 105 to reset.

[0043] The fixed column 106 has a first through groove 1015. The push rod 103 passes through the first through groove 1015 and slides in contact with the fixed column 106, so that the push rod 103 can move up and down in the first through groove 1015. The first through groove 1015 allows the push rod 103 to move up and down stably.

[0044] The fixed column 106 has an inclined groove 1016 with an inclined bottom surface. The end of the push rod 103 is integrally connected to a contact body 1017. The contact body 1017 slides in contact with the bottom surface of the inclined groove 1016. The first spring 1011 is in a compressed state, so that the contact body 1017 is in tight contact with the bottom surface of the inclined groove 1016. When the moving member 105 moves downward, the bottom surface of the inclined groove 1016 cooperates with the contact body 1017 to move the push rod 103 toward the center.

[0045] In this application, a magnetic component is fixedly installed on the upper surface of the movable component 105, and a first electromagnet is fixedly installed at the upper end of the fixed post 106. The first electromagnet has the same magnetic pole as the magnetic component. When the first electromagnet is energized, the movable component 105 will move downward under the action of electromagnetic repulsion, and the second spring 1018 will be compressed. When the first electromagnet is not energized, the movable component 105 will move upward under the action of elasticity.

[0046] In this application, when it is necessary to pick up or put down the lens, the first electromagnet is not energized, and under the action of the first spring 1011 and the second spring 1018, the pressing and fixing surfaces 108 are moved away from each other, which facilitates the picking up and putting down of the lens.

[0047] At the loading and unloading station 300, a loading robot 301 and a unloading robot 302 are provided on one side of the flow line 200. Both the loading robot 301 and the unloading robot 302 are equipped with a suction cup 303 and a guide camera 304. The suction cup 303 is used to pick up the lens, and the guide camera 304 is used to acquire a photograph of the lens, thereby obtaining the position information of the lens or the flow fixture 201.

[0048] In this application, the loading robot 301 and the unloading robot 302 can pick up lenses for testing as needed, realizing autonomous sampling inspection.

[0049] The lens is scribed at the scribing station 400, and a scribing assembly 401 is provided at the scribing station 400.

[0050] The scribing assembly 401 includes: a first straight line module 403, a mounting member 404, and a scribing member 405; the first straight line module 403 is fixedly mounted on the bracket 402, the scribing member 405 is mounted on the mounting member 404, and the mounting member 404 is mounted on the moving part of the first straight line module 403. In use, the first straight line module 403 drives the mounting member 404 to move, and the mounting member 404 drives the scribing member 405 to move. The end of the scribing member 405 contacts the lens to scribing the lens.

[0051] In one embodiment, since the surface of the lens is not flat but curved, a guide 406 is required to allow the scribing member 405 to move along the surface of the lens. In this embodiment, the scribing member 405 consists of a fixed mounting cylinder 407, a moving rod 408, and a third spring 409. The fixed mounting cylinder 407 is fixedly connected to the mounting member 404. The moving rod 408 is slidably disposed within the fixed mounting cylinder 407. The third spring 409 is placed within the fixed mounting cylinder 407. The fixed mounting cylinder 407 can drive the moving rod 408 to move radially along the moving rod 408. The third spring 409 can push the moving rod 408 downward. The third spring 409 is in a compressed state, applying a downward force to the moving rod 408. The guide 406 is fixedly mounted on the bracket 402.

[0052] The guide member 406 has a first guide surface 410 and a second guide surface 411, the first guide surface 410 and the second guide surface 411 having the same shape as the lens surface; the guide member 406 has a second through groove 412, through which the moving rod 408 passes; a limiting part 413 is integrally connected to the moving rod 408, the limiting part 413 slides within the second through groove 412, the limiting part 413 contacts the inner wall of the second through groove 412, the limiting part 413 enables the moving rod 408 to move stably within the second through groove 412, and an abutting part 414 is integrally connected to the moving rod 408, the abutting part 414 contacting the first guide surface 410 and the second guide surface 411.

[0053] The second guide surface 411 is closer to the lens, which makes the contact force between the end of the moving rod 408 and the lens greater. In other words, in this application, by setting guide surfaces of different heights, different forces can be applied to the same lens to make lines.

[0054] In this application, the inclined guide surface is connected to the first guide surface 410 and the second guide surface 411; the second through groove 412 is generally 'n' shaped, and the two ends of the first guide surface 410 and the second guide surface 411 are provided with avoidance guide surfaces 415, the height of the avoidance guide surfaces 415 gradually increases.

[0055] In this application, the mounting component 404 is divided into a fixing component 4031 and a moving plate 4032. The fixing component 4031 is fixedly installed on the moving part of the first linear module 403. The fixing mounting cylinder 407 is fixedly connected to the moving plate 4032. The moving plate 4032 moves on the fixing component 4031. A second positioning groove 4033 is provided on the fixing component 4031. A second positioning block 4034 is fixedly connected to the moving plate 4032. The second positioning block 4034 slides in the second positioning groove 4033.

[0056] The second electromagnet and the third electromagnet are fixedly installed on both sides of the fixing member 4031, and the magnetic suction member is fixedly connected to the moving plate 4032. The second electromagnet and the third electromagnet drive the moving plate 4032 to move, so that the scribing member 405 moves on the inclined guide surface.

[0057] A second linear module 501 is provided at the dust removal station 500. A third linear module 502 is mounted on the second linear module 501. A mounting bracket 503 is mounted on the moving part of the third linear module 502. An air nozzle is mounted on the mounting bracket 503. The second linear module 501 moves the third linear module 502 closer to or further away from the turntable 100. The third linear module 502 moves the mounting bracket 503. Dust is removed by blowing air through the air nozzle, which can prevent dust and impurities from adhering to the lens and avoid affecting the detection.

[0058] The inspection station 600 is equipped with an inspection camera 601 for inspection.
