[0045] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0046] See also Figures 1 to 10 As shown, a lens inspection machine of the present invention comprises a frame 1; a rotating turntable 11 is arranged on the frame 1, and a plurality of clamping mechanisms 2 for clamping lens products and tearing and sticking films on the lens products are arranged around the turntable 11, and the turntable 11 is used to drive the plurality of clamping mechanisms 2 to rotate; along the rotation direction of the turntable 11, the frame 1 is also provided with a loading station 12, a film tearing station 13, a dust suction mechanism 3, a detection mechanism 4, a film closing mechanism 5 and a unloading mechanism 6, the loading station 12 is used to load the lens products to the clamping mechanism 2, and the film tearing station 13 is provided with a positioning component 7, the dust collection mechanism 3, the detection mechanism 4 and the film closing mechanism 5 are all provided with a positioning component 7 and a switching component 8 for switching lenses. The dust collection mechanism 3 is used to remove dust from the lens product, and the detection mechanism 4 is used to detect whether the appearance of the lens product is qualified, specifically to detect whether there is dust and defects on the surface of the lens product; the film closing mechanism 5 is used to adjust the discharging direction of the lens product and assist the clamping mechanism 2 in film application, and the unloading mechanism 6 is used to remove the lens product clamped on the clamping mechanism 2. The frame 1 is also provided with a control connection turntable 11 and a human-machine control interface 9 for each mechanism. In this embodiment, the turntable 11 is driven to rotate by a servo motor installed in the frame 1, and 8 clamping mechanisms 2 are arranged on the turntable 11, and the 8 clamping mechanisms 2 are surrounded at equal angles on the outer edge of the turntable 11; there are two detection mechanisms 4, and the two detection mechanisms 4 are both located between the dust collection mechanism 3 and the film closing mechanism 5.

[0047] In actual production, the human-machine control interface 9 is manually operated to input parameters and start the machine. The lens products are manually clamped onto the clamping mechanism 2 from the loading station 12. The turntable 11 rotates to drive multiple clamping mechanisms 2 to rotate counterclockwise. The clamping mechanisms 2 with lens products clamped pass through and briefly stay at the film tearing station 13, the dust suction mechanism 3, the detection mechanism 4, the film closing mechanism 5 and the unloading mechanism 6 one by one. The positioning component 7 on the film tearing station 13 assists the clamping mechanism 2 to tear off the protective film attached to the lens product. The dust suction mechanism 3 removes dust from the lens product after the film is torn off. The detection mechanism 4 detects whether the dust-free lens product has defects or dust impurities. The lens product after inspection is adjusted to a uniform direction through the film closing mechanism 5 and affixed with a protective film. The unloading mechanism 6 removes the lens product with the protective film and places it in batches according to qualified products and defective products. The lens inspection machine integrates film tearing, dust removal, inspection, film bonding and material unloading and adopts fully automatic operation, making the machine structure more compact, saving floor space, replacing manual operation, improving production efficiency, ensuring product quality, reducing defective product rate and saving labor costs.

[0048] See also Figures 4 to 6 As shown, the clamping mechanism 2 includes a fixed plate 21 fixedly mounted on the turntable 11, the fixed plate 21 is provided with a first moving cylinder 22, a first slide rail 23 and a clamp 24, the first moving cylinder 22 is drivingly connected to a first slider 25, the first slider 25 is slidably connected to the first slide rail 23, the first slider 25 is fixedly connected to a first mounting plate 26, the fixed plate 21 is arranged through the first mounting plate 26, the first mounting plate 26 is symmetrically provided with a film clamping cylinder 27 with the fixed plate 21 as an axis, the film clamping cylinder 27 is drivingly connected to a first connecting member 28, the first connecting member 28 is provided with a spring member 29 and an L-shaped member 210, the spring member 29 is connected to a pressure block 211, the L-shaped member 210 cooperates with the pressure block 211 to form a clamp for clamping the protective film on the lens product; the clamp 24 is provided with a clamping groove and a clearance hole, the clamping groove is used to clamp the lens product, and the clearance hole is used to provide a clearance space for the L-shaped member 210. In this embodiment, the first mounting plate 26 of each clamping mechanism 2 is provided with two upper and lower film clamping cylinders 27, and each film clamping cylinder 27 drives two spring members 29, pressure blocks 211 and L-shaped members 210. There are two clamping grooves on the clamp 24, and both clamping grooves span the clearance holes, and the two clamping grooves correspond to two clamp arrangements.

[0049] In actual application, workers put two lens products into two clamping grooves respectively. When the clamping mechanism 2 is driven by the turntable 11 to the film tearing station 13, the positioning assembly 7 positions the lens products clamped on the fixture 24, and the first moving cylinder 22 extends to drive the first slider 25 to slide on the first slide rail 23. The first slider 25 pushes the first mounting plate 26 to move closer to the lens products. The two film clamping cylinders 27 on the first mounting plate 26 extend at the same time and drive the first connecting members 28 they carry, thereby driving the spring member 29 and the pressing block 211. The L-shaped member 210 is pressed against the lens product. When the pressing block 211 touches the product and continues to move, the spring member 29 is compressed, and the L-shaped member 210 is offset from the pressing block 211 and brushes over the protective film, just like the clamp is in the open state; the two film clamping cylinders 27 retract, thereby driving the L-shaped member 210 and the pressing block 211 away from the lens product. After the pressing block 211 is not under the pressure of the lens product, the spring member 29 recovers its deformation, and the clamp formed by the pressing block 211 and the L-shaped member 210 closes to clamp the protective film and tear it off from the lens product. After the film is torn off, all cylinders are reset. The torn protective film is clamped by the L-shaped member 210 and the pressing block 211 until it reaches the film closing mechanism 5, which cooperates with the film closing mechanism 5 to stick the protective film back on the lens product. The action of the clamping mechanism 2 when sticking the film is the same as the film tearing action.

[0050] See also Figures 3 to 9 As shown, the positioning assembly 7 includes a support member 71, a positioning cylinder 72, and a positioning plate 73. The support member 71 is fixedly mounted on the frame 1, and the positioning cylinder 72 is arranged on the support member 71. The positioning cylinder 72 drives and connects the positioning plate 73, and the positioning plate 73 is used to press the lens product clamped on the positioning fixture 24. The initial state of the positioning cylinder 72 is extended. When the positioning assembly 7 needs to position the lens product, the positioning cylinder 72 retracts, driving the positioning plate 73 to move and press the lens product, so that the clamping mechanism 2 can tear the film and apply the film, the dust collection mechanism 3 can remove dust, and the detection mechanism 4 can detect. After the tearing of the film, dust removal, detection, and film application are completed, the positioning cylinder 72 is reset.

[0051] See also Figures 3 to 9As shown, the switching assembly 8 includes a forward and backward moving cylinder 81 and a switching member 82. The forward and backward moving cylinder 81 drives the switching member 82. The switching member 82 is used to toggle the lens product to switch the lens. Each switching assembly 8 is provided with two forward and backward moving cylinders 81 and two switching members 82 to correspond to the two lens products on the fixture 24. The switching assembly 8 also includes an up and down moving cylinder 84 and a second connecting member 85. The up and down moving cylinder 84 drives the second connecting member 85, and the forward and backward moving cylinder 81 is installed on the second connecting member 85. There are two types of lenses, white sheets and filter sheets, on the lens product. They need to be processed during dust removal and detection, and the material discharge direction needs to be unified according to the customer's requirements during unloading, that is, the white sheets or filters are uniformly facing upwards. Therefore, the switching assembly 8 is used to switch different lenses. When it is necessary to switch the lens, the up and down moving cylinder 84 extends to drive the second connecting member 85 to approach the lens product, and the forward and backward driving cylinder extends or retracts according to the system instruction to drive the switching member 82 to toggle the lens for switching.

[0052] See also Figure 7 As shown, the dust suction mechanism 3 includes a dust suction cylinder 31, a third connecting member 32 and an air suction member 33. The dust suction cylinder 31 can also replace the function of the up-and-down moving cylinder 84. Therefore, the dust suction mechanism 3 does not have the up-and-down moving cylinder 84 and the second connecting member 85. The dust suction cylinder 31 is fixedly installed on the support member 71. The dust suction cylinder 31 drives and connects the third connecting member 32. The air suction member 33 is installed on the third connecting member 32 and is used to perform dust suction on the lens product. The pressure plate is provided with two working holes corresponding to the air suction member 33. The front-and-back moving cylinder 81 is installed on the third connecting member 32. There are two dust suction cylinders 31, the third connecting member 32 and the air suction member 33. The two dust suction cylinders 31 are symmetrically arranged up and down. The air suction member 33 is connected to the external air source and is provided with a plurality of air suction holes. The plurality of air suction holes are divided into two groups and are respectively provided corresponding to the two lens products on the fixture 24. The upper air suction member 33 is provided with two detection sensors 83 corresponding to the two lens products respectively. The detection sensor 83 is used to detect whether the lens is switched normally and determine the position of the lens. When the clamping mechanism 2 transfers the torn lens product to the dust collecting mechanism 3, the two dust collecting cylinders 31 extend at the same time, and each drives the third connecting member 32 to approach the lens product, and the suction member 33 is connected to the external air source. The two groups of suction holes of the suction member 33 respectively vacuum the lens product through the two working holes. After vacuuming one lens, the front-back moving cylinder 81 drives the switching member 82 to switch the lens to the lens that has not been vacuumed. The detection sensor 83 identifies whether the sensing lens is switched normally and determines the position of the lens; the dust collecting cylinder 31 can also replace the function of the up-down moving cylinder 84, so the dust collecting mechanism 3 does not set the up-down moving cylinder 84 and the second connecting member 85. After vacuuming, all cylinders of the dust collecting mechanism 3 are reset.

[0053] See also Figure 8As shown, the detection mechanism 4 includes a second moving cylinder 41, a second slider 42, a second slide rail 43, a second mounting plate 44, a CCD camera 45, a detection cylinder 46, and a bracket 47. The second moving cylinder 41 is mounted on the support 71 and is driven to connect the second slider 42. The second slide rail 43 is set on the support 71. The second slider 42 is slidably connected to the second slide rail 43. The second slider 42 is fixedly connected to the second mounting plate 44. The CCD camera 45, the positioning cylinder 72, and the up-and-down moving cylinder 84 are all mounted on the second mounting plate 44. The detection cylinder 46 is mounted on the pressure plate and is driven to connect the bracket 47. The bracket 47 is provided with a detection sensor 83. The detection sensor 83 is used to detect whether the lens is switched normally and determine the position of the lens. Since one detection mechanism 4 has only one CCD camera 45, the positioning plate 73 of the detection mechanism 4 is only provided with one working hole, and only one lens product can be detected at a time. The second moving cylinder 41 drives the second mounting plate 44 to move horizontally to move the CCD camera 45 from one lens product to another. The positioning component 7 positions a lens product on the fixture 24, and the CCD camera 45 performs visual inspection on the lens product through the working hole. After one lens is inspected, the switching component 8 switches another lens of the lens product, and the detection cylinder 46 extends to drive the detection sensor 83 on the bracket 47 to identify whether the lens is switched normally and perform position identification, and then the CCD camera 45 detects the newly switched lens; when both lenses of a lens product are inspected, the second moving cylinder 41 drives the mounting plate, drives the CCD camera 45, the positioning component 7 and the switching component 8 to another lens product, and then repeats the above inspection process. In this embodiment, two inspection mechanisms 4 are provided, so that the product undergoes two visual inspections, increases the inspection accuracy, and ensures the product quality.

[0054] See also Fig. 9As shown, the film closing mechanism 5 includes a third moving cylinder 51, a third mounting plate 52, a film closing cylinder 53, and a film closing piece 54. The third moving cylinder 51 is installed on the support member 71 and is driven to connect to the third mounting plate 52. The film closing cylinder 53, the up and down moving cylinder 84 and the positioning cylinder 72 are all installed on the third mounting plate 52. The film closing cylinder 53 is driven to connect to the film closing piece 54. The film closing piece 54 is used to assist the clamping mechanism 2 in applying film to the lens product. The positioning plate 73 of the film closing mechanism 5 is provided with two working holes, and a bracket 47 is provided between the two working holes. The bracket 47 is provided with two detection sensors 83 respectively aligned with the working holes. The detection sensor 83 is used to detect whether the lens is switched normally and determine the position of the lens. Before laminating, the discharge direction of the lens products needs to be unified according to customer requirements. When the clamping mechanism 2 sends the inspected lens products to the laminating mechanism 5, the positioning component 7 positions the lens products. The switching component 8 adjusts the discharge directions of the two lens products to be consistent according to the instructions input in advance by the human-machine control interface 9. The third moving cylinder 51 retracts to drive the third mounting plate 52 to move, so that the laminating member 54 is aligned with the lens product. The laminating cylinder 53 drives the laminating member 54 to press against the lens product, thereby assisting the clamping mechanism 2 to laminat the lens product. After laminating, all cylinders of the laminating mechanism 5 are reset.

[0055] Specifically, the detection sensors 83 used by the suction member 33 of the dust suction mechanism 3, the bracket 47 of the detection mechanism 4, and the positioning plate 73 of the film closing mechanism 5 are existing common sensors.

In this embodiment, there are two qualified product areas 611, and the two qualified product areas 611 are respectively provided on both sides of the robot 62, and there is one defective product area 612 and is provided between the robot 62 and the unloading station. The material taking assembly 627 includes a finger cylinder and a material taking clamp driven and connected by the finger cylinder; the material taking assembly 627 can also be a suction piece and a suction nozzle provided for the suction piece.

[0057] After the lens product is filmed, the turntable 11 rotates the clamping mechanism 2 to the unloading station, and the robot 62 drives the material taking component 627 to take the two lens products on the clamping mechanism 2 and put the two lens products into the corresponding receiving tray of the receiving station 61 according to the detection results.
