Description

Technical Field

[0001] The utility model relates to the field of lens detection, in particular to an intelligent lens ex-factory detection device. Background Technique

[0002] A lens is an optical element that refracts light to focus or scatter light, usually made of materials such as glass or plastic. They are widely used in optical instruments such as glasses, camera lenses, microscopes, telescopes, magnifying glasses, and laser devices. Therefore, the quality inspection before lens ex-factory is crucial to ensure that the products meet the specified quality standards. The inspection usually includes surface quality inspection and optical property inspection.

[0003] According to a lens detection device disclosed in Chinese Patent CN219608388U, it includes a box body. The first gear and the second gear are driven by a motor to rotate, so that the threaded lead screw operates, and then the second slider moves. As a result, the box body hinged to one end of the support rod moves up and down through the groove on the baffle, which is convenient for different users to adjust different heights when using. All the detection devices of this device are arranged in the inner box, which improves the protection and safety of the device. When in use, the first electric telescopic rod pushes the tray out of the through hole. When the sensor senses that the placement is completed, the tray retracts. The position of the lens is determined by the sensor, and then the two second telescopic rods fix the lens through the rubber soft heads at the front end, which is convenient for clamping and improves the safety of the lens and the detection device. However, this device still has some limitations:

[0004] 1. Although this device provides solutions for height adjustment and lens fixation, it mainly relies on manual detection operations and lacks an automated process, which limits its application in a large-scale production environment.

[0005] 2. Although this device pays attention to the fixation and protection of the lens, the detection of surface quality and optical properties is relatively simple and does not provide comprehensive detection capabilities. Content of the Utility Model

Detailed implementation manners

[0026] The present utility model will be further described below in conjunction with the attached drawings and embodiments.

[0027] Embodiment: An intelligent inspection device for lens factory production, as Figures 1-5 shown, comprising a base 1, a conveyor belt 2, an electric slide rail 3, a slide seat 4, a cover frame 5, a mounting frame 6, a control panel 60, a control module 61, a detector 62, a laser interferometer 63, a carrier frame 8, a fitting 9, a cylinder I 10, a fixture 11 and a rotation group. The base 1 is the basic support structure of the entire device. In the middle of the top of the base 1, there is a conveyor belt 2, which is used for continuously conveying the lenses to be inspected. On both sides of the conveyor belt 2 at the top of the base 1, there are electric slide rails 3, and a slide seat 4 is slidably arranged on the electric slide rails 3. The electric slide rails 3 provide linear motion for the slide seat 4 and can adjust the position of the slide seat 4. There is a cover frame 5 between the two sides of the base 1. Inside the upper part of the cover frame 5, there is a mounting frame 6. A chute is provided in the upper part of the mounting frame 6. On the left side of the mounting frame 6, there is a control panel 60, which is the user operation interface for displaying the device status and receiving user instructions. On both sides of the inner top of the mounting frame 6, there is a control module 61, which is the core controller for receiving instructions from the control panel 60 and controlling the operation of each component. On the front side of the inner top of the mounting frame 6, there is a detector 62, which is used for detecting the optical characteristics of the lenses (such as diopter, surface defects and manufacturing defects). On the rear side of the inner top of the mounting frame 6, there is a laser interferometer 63, which is used for measuring the radius of curvature of the lenses. Guide grooves 7 are provided on both sides of the mounting frame 6. The groove directions of the front and rear parts of the guide grooves 7 are both bent, and the groove direction in the middle of the guide grooves 7 is higher than that of its front and rear parts. A carrier frame 8 is slidably arranged in the chute in the upper part of the mounting frame 6. On both sides of the lower part of the carrier frame 8, there are fittings 9 slidably arranged. One end of the two fittings 9 close to each other is slidably connected to the two guide grooves 7 on both sides. On both fittings 9 on both sides, there are cylinders I 10 arranged oppositely. On the piston rods of the two cylinders, there are fixtures 11 arranged. When the two cylinders I 10 cooperate, they can drive the two fixtures 11 to clamp and release the lenses. Some of the components included in the rotation group are arranged on the side where the two cylinders I 10 are away from each other, and the other part of the components included in the rotation group are arranged on both sides of the rear part of the mounting frame 6.

[0028] As Figures 3-4 shown, the rotation group includes: a gear 12, a support rod 13, and a rack 14. Gears 12 are rotatably arranged on the sides away from each other of the two side cylinders I 10. Support rods 13 are arranged on both sides of the rear part of the mounting frame 6. Racks 14 are arranged at the front ends of both support rods 13. The gears 12 are rotationally engaged with the racks 14. When the fitting 9 drives the slider 4 and slides along the guide groove 7, the gear 12 on one side of the cylinder I 10 will be rotationally engaged with the rack 14 subsequently. The gear 12 will drive the cylinder I 10 to rotate synchronously, so that the lenses clamped by the two side cylinders I 10 rotate synchronously, thereby realizing all-round detection.

[0029] As Figure 1 , Figure 6 and Figure 7 shown, it further includes a collection box 15, a contact plate 16, and a spring 17. The collection box 15 is movably placed at the lower rear part of the base 1. The collection box 15 has two accommodation cavities to distinguish and collect defective lenses and finished lenses according to the two accommodation cavities. Contact plates 16 are slidably arranged on the tops of the two accommodation cavities of the collection box 15. Springs 17 are arranged between the two contact plates 16 and the inner bottom of the collection box 15 to provide the force for the contact plates 16 to reset.

[0030] As Figure 1 , Figure 6 and Figure 7 shown, it further includes a motor 18 and a support frame 19. The motor 18 is arranged at the bottom of the collection box 15. The output shaft of the motor 18 extends into the inner side of the collection box 15 and is connected to the upper part of the collection box 15. The motor 18 can drive the collection box 15 to rotate. Support frames 19 are arranged at the positions near the rear of both sides of the lower part of the base 1 to support the motor 18 and the collection box 15. The rear parts of both support frames 19 are connected to the outer side of the motor 18.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, it further includes a protection plate 20, a buffer table 21, and a baffle 22. The protection plate 20 is arranged on the top of the collection box 15 to prevent the lenses from overflowing from the collection box 15. A buffer table 21 is arranged between the front sides of both sides of the protection plate 20. The front side of the buffer table 21 contacts the rear side of the conveyor belt 2. The buffer table 21 is inclined. The buffer table 21 can slow down the speed of the lenses when they fall on the contact plate 16, avoid damage to the lenses or generate unnecessary noise. At the same time, the buffer table 21 can also ensure that the lenses smoothly transition to the contact plate 16 and then enter the collection box 15, improving the efficiency of the collection process. Baffles 22 are symmetrically arranged on the front and rear sides of the outer side of the conveyor belt 2 to prevent the lenses from accidentally falling to the ground and reducing losses.

[0032] As Figure 1and Figure 3 As shown, it further includes a folding rod 23, a cylinder II 24 and a partition plate 25. A folding rod 23 is provided in the middle of the front side of the mounting bracket 6 for supporting components. A cylinder II 24 is provided on the front side of the folding rod 23. A partition plate 25 is provided on the piston rod of the cylinder II 24. The bottom of the partition plate 25 contacts above the conveyor belt 2. The cylinder II 24 is used to drive the partition plate 25. The partition plate 25 can form a block on the conveyor belt 2 to control the flow of the lenses, facilitating detection. The position of the lenses on the conveyor belt 2 can be controlled through the partition plate 25 to ensure that only one lens is sent into the detection area each time. The electric slide rail 3, the conveyor belt 2, the control module 61, the detector 62, the laser interferometer 63, the cylinder I 10 and the cylinder II 24 are all electrically connected to the control screen 60. The control screen 60 can control the actions of these components and receive data from the detector 62 and the laser interferometer 63 to achieve the automatic control of the entire detection process.

[0033] First, start the conveyor belt 2 through the control panel 60. Place the lens to be detected at the starting end of the conveyor belt 2. The partition 25 forms a block on the conveyor belt 2 through the drive of the cylinder II 24 to ensure that only one lens passes through the detection area each time. When the lens reaches the predetermined position, drive the carriage 4 through the electric slide rail 3 to move the bearing seat under the lens, align the fitting 9 with the lens. Subsequently, start the cylinders I 10 on both sides through the control panel 60 to drive the fixture 11 to close and clamp the lens. After the fixture 11 clamps the lens, with the drive of the carriage passing through the slide rail 4, the fitting 9 slides along the guide groove 7 to lift the lens to the detection position. The design of the guide groove 7 enables the lens to move smoothly to the detection position. When the fitting 9 slides along the guide groove 7, the gear 12 on one side of the cylinder I 10 meshes with the rack 14 to rotate, driving the cylinder I 10 to rotate, thereby synchronously rotating the clamped lens for omnidirectional detection. The detector 62 performs surface quality detection while the lens is rotating to check for scratches, bubbles or other defects. And the conveyor belt can be set to be made of a material that is entirely black to ensure sufficient light but not directly irradiate the lens to avoid glare interference. The laser interferometer 63 will measure the radius of curvature of the lens. The detector 62 further measures the optical properties such as the dioptric power and refractive index of the lens. The detection data will be processed by the control module 61 and compared with the design requirements. According to the detection results, the control module 61 will determine whether the lens is qualified. The qualified lens is released by the fixture 11, smoothly transitions to the contact plate 16 through the buffer table 21 and squeezes the spring 17 as the weight increases, causing the contact plate 16 to slide down, so that the lens enters one of the cavities of the collection box 15. In case of an unqualified lens, first keep the fixture 11 in the clamping state, and start the motor 18. The motor 18 drives the collection box 15 to rotate, rotates the other cavity of the collection box 15 to the blanking position, and then drives the fixture 11 to release. The defective lens will transition to the contact plate 16 of the other cavity and be collected. The control panel 60 receives user instructions and controls the automatic execution of the entire detection process. And the electric slide rail 3, conveyor belt 2, control module 61, detector 62, laser interferometer 63, cylinder I 10 and cylinder II 24 are all electrically connected to the control panel 60 to achieve data transmission and coordinated movement of components. When the detection and classification of one lens are completed, all components of the device return to the initial state to prepare for the detection of the next lens.

However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present utility model.
