Technical Field

[0001] The present invention relates to a detection device, in particular to a glass optical detection device applied in the field of optical detection technology. Background Art

[0002] Optical glass is a special glass material used to manufacture various optical components, such as lenses, prisms, reflectors, etc. This glass has highly uniform chemical composition and physical properties to ensure that its optical performance reaches high standards. Optical glass will still have surface and internal defects after polishing. Surface and internal defects of optical glass will reduce the damage resistance of optical glass and affect the imaging quality of optical glass system.

[0003] Chinese invention patent CN111289540B discloses an optical glass defect detection device and a thickness calculation method thereof. The application of its optical fiber bundle can avoid the time-consuming problem caused by axial scanning, and only one-dimensional scanning is required to complete the measurement, which greatly improves the measurement efficiency. It is easy to use, has a wide detection range, high detection efficiency, high measurement accuracy, and can realize the detection of upper and lower surfaces, sub-surfaces and internal defects of the optical glass being tested.

[0004] Since optical glass is easily affected by external stray light during inspection, shading treatment is required during optical inspection. However, existing optical inspection equipment lacks a fully enclosed shading structure. At the same time, the use of a fully enclosed shading device affects the replacement of glass and the efficiency of glass inspection. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing optical detection equipment lacks a fully enclosed shading structure, and the use of a fully enclosed shading device affects the replacement of glass and the efficiency of glass detection.

[0006] In order to solve the above problems, the present invention provides a glass optical inspection device, including an equipment body, a transmission turntable is rotatably connected to the middle of the equipment body, a transport module is fixedly connected to the periphery of the transmission turntable, a mechanical rail frame is fixedly connected to the top of the equipment body, a detection module is slidably connected to one end of the mechanical rail frame, and the detection module corresponds vertically to the transport module;

[0007] The transport module is composed of a carrier plate and a cover, the carrier plate and the cover are connected in a lifting and lowering manner, a detection window is provided in the middle of the cover, and door cover pages are slidably connected at both ends of the upper opening of the detection window;

[0008] The detection module is composed of a light-shielding detection bag and a swinging electric rail. The light-shielding detection bag is arranged in a V shape, and the two ends of the top of the light-shielding detection bag are respectively fixedly connected with a light source module and a camera module. The light source module and the camera module are fixedly connected to the movable end of the swinging electric rail. The lower opening of the light-shielding detection bag vertically corresponds to the detection window, and the lower opening of the light-shielding detection bag is fixedly connected to a lip ring on the outside, and the lip ring is inserted between two door cover leaves. A push cylinder is fixedly connected to the bottom of the swinging electric rail, and the output end of the push cylinder is in contact with the end of the lip ring away from the transport module.

[0009] In the above-mentioned glass optical inspection equipment, a closed optical inspection environment is formed by the transport module and the inspection module, thereby effectively reducing the influence of external light sources on the inspection, and by pressing the lip ring to deform and propping up the door cover, the docking efficiency between the transport module and the inspection module is effectively improved, and the exposure time and range of the inspection environment are minimized.

[0010] As a further improvement of the present application, the two deformation states of the lip ring are flat long strip and circular, and the lip ring is made of spring steel material. The lip ring in the flat state realizes the closure of the lower opening of the light-shielding detection bag, and the lip ring in the circular state realizes the propping up of the two door cover pages and opening the lower opening of the light-shielding detection bag. The lip ring made of spring steel material is easy to restore to the flat long strip shape.

[0011] As a further improvement of the present application, both ends of the inner circle of the lip ring are fixedly connected with lip gaskets, and the lip gaskets are made of sponge material. When the lip ring returns to a flat and long strip shape, the two lip gaskets are pressed against each other to effectively improve the closing effect of the lip ring and the lower opening of the light-shielding detection bag.

[0012] As a further improvement of the present application, a resistance groove is fixedly connected to the top of one adjacent end of the two door cover pages, and the resistance groove is correspondingly engaged with the outer ring of the lip ring, effectively improving the resistance effect between the lip ring and the door cover page, thereby effectively improving the opening effect of the door cover page.

[0013] As another improvement of the present application, edge covers are fixedly connected to both ends of the top of the cover, and a closing spring is fixedly connected between the abutting groove and the edge cover. The elastic force of the closing spring is used to push the abutting groove to achieve automatic closing of the two door cover leaves.

[0014] As another improvement supplement of the present application, side holes are provided at one end of the carrier plate and the cover close to the detection module, and an insertion bracket is fixedly connected to the bottom of the swinging electric rail, and the insertion bracket is inserted into the side hole, and a sub-camera module is fixedly connected to the insertion end of the insertion bracket, and the sub-camera module vertically corresponds to the detection window. The sub-camera module passes through the side hole through the insertion bracket, so that the sub-camera module is in the carrier plate, thereby detecting the light transmittance of the glass, effectively improving the optical detection effect of the glass.

[0015] As another improvement supplement of the present application, both ends of the inner wall of the side hole are fixedly connected with closed valves, and the closed valves are made of elastic rubber material. The side hole is closed by the closed valves, which effectively improves the shading effect of the side hole.

[0016] As another improvement of the present application, the other end of the mechanical rail frame is slidably connected to a pick-and-place robot, and the end of the pick-and-place robot close to the transport module is movably connected to a pick-and-place clamp, the side hole corresponds horizontally to the pick-and-place clamp, and the pick-and-place clamp extends between the carrier plate and the cover through the side hole, thereby facilitating the taking out and putting in of the glass inside the transport module, effectively improving the storage efficiency of the glass to be tested.

[0017] As another improvement supplement of the present application, a cover opening support claw is provided on the outside of the pick and place clamp, and the cover opening support claw is slidably connected to the bottom of the pick and place robot, and the cover opening support claw corresponds to the bottom of both ends of the cover. When the pick and place clamp is used to clamp the glass, the two cover opening support claws are first used to prop the cover upward to provide space for the pick and place clamp to pick and place the glass, thereby effectively improving the glass picking and placing efficiency of the pick and place clamp.

[0018] In summary, the present invention effectively reduces the influence of external light sources on the optical detection of glass by performing optical detection of glass in a closed environment between the transport modules, thereby effectively improving the optical detection effect of glass, and when the detection module is docked with the transport module, the lip ring of the lower opening of the light-shielding detection bag is inserted between the door cover pages at the top of the cover, and then pressure is applied to the lip ring so that the lip ring is deformed to prop open the door cover pages, thereby connecting the lower opening of the light-shielding detection bag with the detection window, effectively improving the docking efficiency and effect of the detection module and the transport module, and when the detection module is not docked with the transport module, the detection module and the transport module are both in a closed state, effectively reducing the influence of the external environment on the light-shielding detection bag and the inside of the carrier during the switching of the transport modules.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figures 1 to 5 FIG. 1 shows a glass optical inspection device, comprising an equipment body 1, a transmission turntable 2 is rotatably connected to the middle of the equipment body 1, a transport module 3 is fixedly connected to the periphery of the transmission turntable 2, a mechanical rail frame 4 is fixedly connected to the top of the equipment body 1, an inspection module 5 is slidably connected to one end of the mechanical rail frame 4, the inspection module 5 is vertically corresponding to the transport module 3, the transport module 3 is composed of a carrier plate 301 and a cover 302, the carrier plate 301 is movably connected to the cover 302, and an inspection module 5 is provided in the middle of the cover 302. The detection window 303, both ends of the upper opening of the detection window 303 are slidably connected with door cover pages 304, the detection module 5 is composed of a light-shielding detection bag 501 and a swinging electric rail 502, the light-shielding detection bag 501 is arranged in a V shape, and the top ends of the light-shielding detection bag 501 are respectively fixedly connected with a light source module 503 and a camera module 504, the light source module 503 and the camera module 504 are both fixedly connected to the movable end of the swinging electric rail 502, and the lower opening of the light-shielding detection bag 501 is vertically corresponding to the detection window 303;

[0033] When conducting optical inspection of glass, the glass to be tested is placed in the transport module 3 and is rotated and transported through the transport turntable 2, and is docked and inspected with the inspection modules 5 one by one, that is, the lower opening of the shading inspection bag 501 is docked with the inspection window 303, and the light source module 503 and the camera module 504 perform optical inspection on the glass to be tested through the inspection window 303. The inspection environment is in a closed environment throughout the process, which effectively reduces the influence of external light sources on the optical inspection of glass, thereby effectively improving the optical inspection effect of glass. The light source module 503 and the camera module 504 are adjusted in angle on the swing electric rail 502, that is, the V-shaped shading inspection bag 501 is opened and closed, so as to realize multi-angle optical inspection of the glass to be tested.

[0034] Figures 3 to 7 It is shown that a lip ring 505 is fixedly connected to the outside of the lower opening of the shading detection bag 501, and the lip ring 505 is inserted between the two door cover pages 304. A pushing cylinder 506 is fixedly connected to the bottom of the swing electric rail 502, and the output end of the pushing cylinder 506 is in contact with the end of the lip ring 505 away from the transport module 3. The two deformation states of the lip ring 505 are flat and long and circular, and the lip ring 505 is made of spring steel material. The lip ring 505 in the flat state realizes the closure of the lower opening of the shading detection bag 501, and the lip ring 505 in the circular state realizes the opening of the two door cover pages 304 and opens the lower opening of the shading detection bag 501. The lip ring 505 made of spring steel material is easy to restore to the flat and long shape, and the inner ring of the lip ring 505 is fixedly connected with lip gaskets at both ends. 509, the lip gasket 509 is made of sponge material. When the lip ring 505 returns to a flat long strip shape, the two lip gaskets 509 are pressed against each other to effectively improve the closing effect of the lip ring 505 and the lower opening of the light-shielding detection bag 501. The top of the adjacent end of the two door cover pages 304 is fixedly connected with a resistance groove 305, and the resistance groove 305 is corresponding to the outer ring of the lip ring 505, which effectively improves the resistance effect between the lip ring 505 and the door cover page 304, thereby effectively improving the opening effect of the door cover page 304. The top ends of the cover 302 are fixedly connected with edge covers 306, and a closing spring 307 is fixedly connected between the resistance groove 305 and the edge cover 306. The elastic force of the closing spring 307 is used to push the resistance groove 305 to realize the automatic closing of the two door cover pages 304.

[0035] When the transport module 3 and the detection module 5 are docked, the detection module 5 slides on the mechanical rail 4 to approach the transport module 3, the lower opening of the light-shielding detection bag 501 moves toward the cover 302, and the lip ring 505 of the lower opening of the light-shielding detection bag 501 is inserted between the two door cover pages 304, that is, the outer ring of the lip ring 505 is inserted into the abutment groove 305 until the lip ring 505 abuts against the inner edge of the cover 302. At this time, the detection module 5 is still sliding on the mechanical rail 4, and the push cylinder 506 is pushed to the transport module 3. Pressure is applied to the lip ring 505 at one end away from the transport module 3, and the flat and long lip ring 505 is deformed into a circle, which opens and separates the door cover 304, thereby exposing the detection window 303 shielded by the door cover 304, and finally the lower mouth of the light-shielding detection bag 501 is docked with the detection window 303, so that the originally closed transport module 3 and the originally closed detection module 5 are docked, which effectively improves the efficiency and effect of the docking of the detection module 5 and the transport module 3, and minimizes the time and scope of exposure to the detection environment.

[0036] The second implementation method:

[0037] Compared with the first embodiment, this embodiment mainly adds a side hole 308. The specific newly added structure is as follows, and the remaining structure is consistent with the first embodiment.

[0038] Figure 1 , Figure 4 and Figure 8 As shown, a side hole 308 is provided at one end of the carrier 301 and the cover 302 close to the detection module 5, and an insertion bracket 507 is fixedly connected to the bottom of the swing electric rail 502, and the insertion bracket 507 is inserted into the side hole 308, and the insertion end of the insertion bracket 507 is fixedly connected to a sub-camera module 508, and the sub-camera module 508 is vertically corresponding to the detection window 303. The sub-camera module 508 passes through the side hole 308 through the insertion bracket 507, so that the sub-camera module 508 is in the carrier 301, so as to detect the light transmission effect of the glass, effectively improving the optical detection effect of the glass, and the inner wall of the side hole 308 is fixedly connected with a closed valve 309 at both ends, and the closed valve 309 is made of elastic rubber material, and the side hole 308 is closed by the closed valve 309, which effectively improves the light shielding effect of the side hole 308;

[0039] When the transport module 3 and the detection module 5 are docking, the auxiliary camera module 508 extends into the bracket 507 and passes through the side hole 308. Originally, the side hole 308 is light-shielded and closed by the closed valve 309. Finally, the auxiliary camera module 508 is placed in the carrier 301, so that the auxiliary camera module 508 can record the wire bundle transmitted through the glass to be tested, effectively improve the light transmission effect of the tested glass, and better judge the quality of the glass.

[0040] Figure 1 and Fig. 9As shown, the other end of the mechanical rail 4 is slidably connected with a pick-and-place manipulator 6, and one end of the pick-and-place manipulator 6 close to the transport module 3 is movably connected with a pick-and-place clamp 601, and the side hole 308 corresponds horizontally to the pick-and-place clamp 601. The pick-and-place clamp 601 extends through the side hole 308 between the carrier 301 and the cover 302, thereby facilitating the taking out and putting in of the glass inside the transport module 3, and effectively improving the storage efficiency of the glass to be tested. The outside of the pick-and-place clamp 601 is provided with a cover opening support claw 602, which is slidably connected to the bottom of the pick-and-place manipulator 6, and the cover opening support claw 602 corresponds to the bottom of both ends of the cover 302. When the pick-and-place clamp 601 clamps the glass, the cover opening support claw 602 is first used to prop the cover 302 upward to provide space for the pick-and-place clamp 601 to take and put the glass, effectively improving the glass taking and putting efficiency of the pick-and-place clamp 601.

[0041] When the glass after inspection by the transport module 3 reaches the other end of the mechanical rail 4, the pick-and-place robot 6 picks and places the glass in the transport module 3, that is, the pick-and-place clamp 601 extends through the side hole 308 into between the carrier 301 and the cover 302 to clamp the glass, thereby taking out the inspected glass and placing new glass to be inspected, and effectively improving the efficiency of optical inspection of the glass. Before the pick-and-place clamp 601 extends into the side hole 308, the cover opening support claw 602 first opens the cover 302 upward to provide space for the pick-and-place clamp 601 to pick and place the glass, thereby effectively improving the glass picking and placing efficiency of the pick-and-place clamp 601.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
