Description

Technical Field

[0001] This invention relates to the field of fisheye lens inspection technology, specifically to a 5-megapixel fisheye lens. It also relates to an inspection device for a 5-megapixel fisheye lens. Background Technology

[0002] Fisheye lenses are typically lenses with a field of view of 140° or more. Due to their extremely large field of view, especially those exceeding 180°, they offer a completely unobstructed imaging experience, making them commonly used in video doorbells, security monitoring, panoramic cameras, action camcorders, and automotive applications. In video doorbells, the lens is a core component. The market has placed many demands on these lenses—large field of view, large sensor size, large aperture, high resolution, day / night focus, compact design, waterproofing, and good weather resistance, among others. Currently, existing lenses typically employ a hybrid glass-plastic structure to achieve a compact design.

[0003] Existing testing equipment for fisheye lenses typically only allows for testing at a fixed position. This method cannot detect the effect of fisheye lenses under rotation or vibration conditions, resulting in low testing efficiency and incomplete testing functions. It cannot provide high-quality fisheye lenses. When used in fields such as video doorbells, security monitoring, and drones, it is necessary to provide stable visual display of fisheye lenses under vibration or rotation conditions.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This fisheye lens is mainly composed of a glass spherical lens and a plastic aspherical lens. The number of lenses is reasonable, and the first lens is made of glass, which has high hardness. This fisheye lens has many advantages such as scratch resistance, low development cost, large image area, compact structure, no blind spots in imaging, day and night confocal focus, and high clarity. It is suitable for video doorbells, security monitoring and other fields.

[0017] 2. This invention enables efficient and accurate inspection of fisheye lenses, allowing for inspection under various conditions. It can detect the imaging function of fisheye lenses in static, rotating, and vibrating states, thereby determining the lens's production quality.

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-13The 5-megapixel fisheye lens shown includes a housing 1 and a lens assembly mounted within the housing 1. The housing 1 includes a first mounting tube 2 and a second mounting tube 3. The lens assembly, along the optical axis from the object side to the image side, includes a first lens 4, a second lens 5, an aperture 6, a third lens 7, a fourth lens 8, a fifth lens 9, a sixth lens 10, and a filter 11. The first lens 4 is a glass lens with negative optical power, with a convex object side and a concave image side. The second lens 5 has negative optical power, with a concave object side and a convex image side. The third lens 7 has positive optical power, with a convex object side and a convex image side. The fourth lens 8 has positive optical power. The fourth lens 8 has a convex object plane and a convex image plane; the fifth lens 9 has negative optical power, with both its object plane and image plane being concave; the sixth lens 10 has positive optical power, with both its object plane and image plane being convex; the fourth lens 8 and the fifth lens 9 are bonded together to form a cemented lens, which has negative optical power; the third lens 7, the fourth lens 8, and the fifth lens 9 are glass lenses, the second lens 5 and the sixth lens 10 are plastic lenses, the first lens 4, the third lens 7, the fourth lens 8, and the fifth lens 9 are spherical lenses, the second lens 5 and the sixth lens 10 are aspherical lenses, the fourth lens 8 is a symmetrical biconvex lens, and the fifth lens 9 is a symmetrical biconcave lens.

[0036] Compared with the prior art, the fisheye lens provided by the present invention includes, along the optical axis from the object side to the image side, a first lens 4, a second lens 5, an aperture 6, a third lens 7, a fourth lens 8, a fifth lens 9, a sixth lens 10, and a filter 11. The first lens 4, the third lens 7, the fourth lens 8, and the fifth lens 9 are spherical lenses, while the second lens 5 and the sixth lens 10 are aspherical lenses. This invention solves the problems of being not scratch-resistant, having high development costs, and not having a large enough image height. It has the advantages of being scratch-resistant, having low development costs, having a large image area, having a compact structure, having no dead angles in imaging, being confocal day and night, and having high sharpness.

[0037] In specific implementation, the lens consists of a first lens 4, a second lens 5, an aperture stop 6, a third lens 7, a fourth lens 8, a fifth lens 9, and a sixth lens 10 arranged in sequence, and a filter 11. The fourth lens 8 and the fifth lens 9 are bonded together to form a cemented lens, and the aperture stop 6 is located between the second lens 5 and the third lens 7. Light enters from the object side and passes through the first lens 4, the second lens 5, the aperture stop 6, the third lens 7, the fourth lens 8, the fifth lens 9, the sixth lens 10, and the filter 11 in sequence to the image sensor.

[0038] This fisheye lens is mainly composed of a glass spherical lens and a plastic aspherical lens. The number of lenses is reasonable, and the first lens 4 is made of glass, which has high hardness. This fisheye lens has many advantages such as scratch resistance, low development cost, large image area, compact structure, no blind spots in imaging, day and night confocal focus, and high clarity. It is suitable for fields such as video doorbells and security monitoring.

[0039] An inspection device for a 5-megapixel fisheye lens includes a multi-station turntable 12 and a loading mechanism 13, a lifting inspection mechanism 14, a rotating inspection mechanism 15, a vibration inspection mechanism 16, and a unloading mechanism 17 sequentially installed beside each station of the multi-station turntable 12. The multi-station turntable 12 includes a loading station, an initial inspection station, a rotating inspection station, a vibration inspection station, and an unloading inspection station. Each station of the multi-station turntable 12 is equipped with a clamping mechanism 18. The lifting inspection mechanism 14 has three sets, which are positioned at the initial inspection station, the rotating inspection station, and the vibration inspection station. The lifting inspection mechanism 14 includes... The system includes a detection camera 19 capable of moving vertically and a detection box 20 capable of assisting detection in the vertical direction. A first clearance groove 21 for avoiding the detection camera 19 is provided on the multi-station turntable 12. A material handling robot 22 for clamping the lens housing 1 and a conveyor belt 23 for transporting the lens housing 1 are provided on the sides of the loading mechanism 13 and the unloading mechanism 17. The clamping mechanism 18 is connected to the material handling robot 22. The material handling robot 22 is provided with a first clamping claw 24 for clamping the housing 1 and a first abutting block 25 for driving the clamping mechanism 18 to open and close. The clamping mechanism 18 is provided with a second abutting block 26 connected to the first abutting block 25.

[0040] When the fisheye lens needs to be inspected, the picking robot 22 in the loading mechanism 13 clamps the fisheye lens on the conveyor belt 23 in the loading mechanism 13. The first gripper 24 clamps the outer shell 1 of the fisheye lens and moves it to the upper part of the loading station of the multi-station turntable 12. At this time, the picking robot 22 descends, and the first abutment block 25 and the second abutment block 26 engage in a transmission, causing the clamping mechanism 18 on the loading station to open. After the picking robot 22 releases, the transmission engagement of the first abutment block 25 and the second abutment block 26 is released, and the clamping mechanism 18 resumes its clamping function, accurately clamping the fisheye lens. When the fisheye lens moves to the initial inspection station, the inspection camera 19 below and the inspection box 20 above inspect the fisheye lens. The fisheye lens undergoes initial testing. When the fisheye lens moves to the rotary testing station, the rotary testing mechanism 15 drives the fisheye lens to rotate around its own axis on the clamping mechanism 18. At this time, the testing camera 19 located below it detects the fisheye lens during the rotation process. When the fisheye lens moves to the vibration testing station, the vibration testing mechanism 16 drives the fisheye lens to vibrate. The testing camera 19 below the vibration testing station detects the fisheye lens under vibration. After all tests are completed, the material handling robot 22 in the unloading mechanism 17 clamps the fisheye lens in the clamping mechanism 18 located at the unloading station and transfers the fisheye lens to the conveyor belt 23 in the unloading mechanism 17 to realize the testing function.

[0041] This invention enables efficient and accurate inspection of fisheye lenses, allowing for testing under various conditions. It can inspect the imaging function of fisheye lenses in static, rotating, and vibrating states, thereby determining the lens's production quality. This achieves the function of inspecting fisheye lenses, ensuring stable imaging under complex conditions, improving product applicability, and guaranteeing product quality.

[0042] The clamping mechanism 18 includes a first mounting frame 27, a hinge rod 28, a sliding rod 29, a clamping spring 30, and a semi-circular gripper 31. The first mounting frame 27 is fixedly mounted on the multi-station turntable 12. Two hinge rods 28, two sliding rods 29, two abutment blocks 26, and two semi-circular grippers 31 are provided and symmetrically arranged vertically along the first mounting frame 27. The hinge rod 28 is rotatably mounted at the bottom end of the first mounting frame 27. Both the hinge rod 28 and the sliding rod 29 are horizontally fixedly mounted on the semi-circular gripper 31. The sliding rod 29 is slidably mounted on the first mounting frame 27. The first mounting bracket 27 is provided with an arc-shaped groove 32 for sliding the end of the sliding rod 29. The center of the arc of the arc-shaped groove 32 is concentric with the hinge rod 28. The second abutment block 26 is fixedly installed on the semi-arc gripper 31. There are four clamping springs 30, which are located at the ends of the two sliding rods 29 respectively. One end of the clamping spring 30 is fixedly connected to the side wall of the first mounting bracket 27, and the other end of the clamping spring 30 is fixedly connected to the end of the sliding rod 29. The outer shell 1 is configured to rotate around its own axis within the semi-arc gripper 31. The outer shell 1 is mounted on the semi-arc gripper 31 with vibration.

[0043] When the clamping mechanism 18 is working, the clamping spring 30 provides clamping force to the semi-arc gripper 31 on the outer shell 1. When the picking robot 22 descends, the first abutment block 25 drives the second abutment block 26 mounted on the semi-arc gripper 31, causing the semi-arc gripper 31 to deflect outward around the axis of the hinge rod 28. At this time, the other end of the semi-arc gripper 31 slides in the arc-shaped slide groove 32 of the first mounting frame 27 through the sliding rod 29, so that the two semi-arc grippers 31 separate. After the outer shell 1 is placed in place, the transmission connection between the first abutment block 25 and the second abutment block 26 is released. The semi-arc gripper 31 is reset under the elastic force of the clamping spring 30, and then clamps the outer shell 1 located between the two semi-arc grippers 31, realizing the automatic non-drive clamping function.

[0044] The semi-circular gripper 31 includes a first arc-shaped gripper 33, a second arc-shaped gripper 34, and a clamping mounting plate 35. The arc of the first arc-shaped gripper 33 is consistent with the outer side wall of the first mounting cylinder 2, and the arc of the second arc-shaped gripper 34 is consistent with the outer side wall of the second mounting cylinder 3. The first arc-shaped gripper 33 is located directly above the second arc-shaped gripper 34. Both the first arc-shaped gripper 33 and the second arc-shaped gripper 34 are fixedly mounted on the clamping mounting plate 35. One end of the clamping mounting plate 35 is fixedly connected to the hinge rod 28, and the other end of the clamping mounting plate 35 is fixedly connected to the sliding rod 29.

[0045] The semi-circular gripper 31 clamps the outer wall of the first mounting cylinder 2 through the first arc-shaped gripper 33, and the second arc-shaped gripper 34 clamps the outer wall of the second mounting cylinder 3. The clamping mounting plate 35 is used to install the first arc-shaped gripper 33 and the second arc-shaped gripper 34. The design of the semi-circular gripper 31 can more accurately achieve the clamping function of the outer shell 1.

[0046] The lifting detection mechanism 14 also includes a first lifting drive assembly and a second lifting drive assembly. The first lifting drive assembly includes a first lifting frame 36 and a first lifting driver 37. The first lifting driver 37 is vertically arranged below the multi-station turntable 12. The first lifting frame 36 is located directly below the first clearance groove 21. The output end of the first lifting driver 37 is fixedly connected to the first lifting frame 36. The detection camera 19 is vertically fixedly installed on the top of the first lifting driver 37. The second lifting drive assembly includes a second lifting frame 38 and a second lifting driver 39. The second lifting driver 39 and the second lifting frame 38 are both located beside the multi-station turntable 12. The second lifting driver 39 is vertically arranged. The second lifting frame 38 is vertically arranged on the top of the second lifting driver 39 and is fixedly connected to the output end of the second lifting driver 39. The detection box 20 is vertically fixedly installed on the side of the second lifting frame 38 away from the second lifting driver 39.

[0047] When the lifting detection mechanism 14 is working, the lifting operation of the detection camera 19 is controlled by the first lifting drive component. The first lifting driver 37 drives the first lifting frame 36 to lift and lower below the multi-station turntable 12, thereby driving the detection camera 19, which is fixedly installed on the first lifting frame 36, to lift and lower synchronously, thus realizing the driving function of the detection camera 19. The lifting operation of the detection box 20 is controlled by the second lifting drive component. The second lifting driver 39 drives the second lifting frame 38 to lift and lower beside the multi-station turntable 12, thereby driving the detection box 20, which is fixedly installed on the second lifting frame 38, to lift and lower synchronously, thus realizing the driving function of the detection box 20.

[0048] Both the rotary detection mechanism 15 and the vibration detection mechanism 16 are equipped with horizontal pushing components. The rotary detection mechanism 15 also includes a rotary drive component, and the vibration detection mechanism 16 also includes a vibration drive component. The horizontal pushing component is located beside the multi-station turntable 12. The output direction of the horizontal pushing component is consistent with the radial direction of the multi-station turntable 12. The horizontal pushing component includes a horizontal driver 40, a second mounting bracket 41, and a sliding mounting bracket 42. The second mounting bracket 41 is located beside the multi-station turntable 12. The horizontal driver 40 is fixedly mounted on the second mounting bracket 41. The sliding mounting bracket 42 is slidably mounted on the second mounting bracket 41. The output end of the horizontal driver 40 is consistent with the radial direction of the multi-station turntable 12. The output end of the horizontal driver 40 is fixedly connected to the sliding mounting bracket 42. The direction of the sliding mounting bracket 42 is consistent with the output direction of the horizontal driver 40. The rotary drive component and the vibration drive component are respectively mounted on the two sliding mounting brackets 42.

[0049] When the rotary detection mechanism 15 and the vibration detection mechanism 16 are working, they both achieve horizontal displacement through the horizontal pushing component. When the multi-station turntable 12 rotates, the horizontal pushing component is in the initial position. When detection is required, the horizontal pushing component pushes the rotary drive component or the vibration drive component into the clamping mechanism 18, so that the rotary drive component or the vibration drive component can achieve the transmission function with the fisheye lens clamped on the clamping mechanism 18.

[0050] When the horizontal drive component is working, the horizontal driver 40 installed on the second mounting bracket 41 outputs, driving the sliding mounting bracket 42, which is connected to the horizontal driver 40, to move in the horizontal direction. During the movement, the sliding mounting bracket 42 drives the rotary drive component or vibration drive component fixed on it to move synchronously, thereby realizing the push drive function.

[0051] The rotary drive assembly includes a first rotary driver 43, a rotating shaft 44, and a drive belt 45. The two rotating shafts 44 are vertically mounted at both ends of the sliding mounting bracket 42. The first rotary driver 43 is fixedly mounted at one end of the sliding mounting bracket 42 near the horizontal driver 40. The output end of the first rotary driver 43 is fixedly connected to one end of one of the rotating shafts 44. The drive belt 45 is sleeved on the two rotating shafts 44. The outer side wall of the drive belt 45 away from the first rotary driver 43 is in contact with the outer side wall of the second mounting cylinder 3. Several rotating rollers 46 are provided on the inner side walls of the first arc-shaped claw 33 and the second arc-shaped claw 34. The rotating rollers 46 are vertically and rotatably mounted on the first arc-shaped claw 33 or the second arc-shaped claw 34. The several rotating rollers 46 are evenly distributed around the arc center of the first arc-shaped claw 33 or the second arc-shaped claw 34. The rotating rollers 46 are in contact with the outer side wall of the first mounting cylinder 2 or the outer side wall of the second mounting cylinder 3.

[0052] When the rotary drive assembly is working, the output of the first rotary driver 43 drives one of the rotating shafts 44 to rotate. The rotating shaft 44 drives the other rotating shaft 44 to rotate synchronously through the drive belt 45. At the same time, due to the rotation of the drive belt 45, the second mounting cylinder 3, which is in contact with the outer surface of the drive belt 45, rotates, thereby realizing the rotary drive function of the fisheye lens.

[0053] The rotating roller 46 is installed on the first arc-shaped claw 33 and the second arc-shaped claw 34 so that the fisheye lens can rotate around its own axis under the clamping of the clamping mechanism 18. The rotating roller 46 changes the sliding friction between the first mounting cylinder 2 or the second mounting cylinder 3 and the semi-arc-shaped claw 31 into rolling friction.

[0054] The vibration drive assembly includes a second rotary driver 47, a cam 48, an abutment rod 49, and an abutment spring 50. The second rotary driver 47 is fixedly mounted on a sliding mounting bracket 42. The cam 48 is horizontally rotatable and mounted on the sliding mounting bracket 42. The output end of the second rotary driver 47 is fixedly connected to the cam 48. The abutment rod 49 is horizontally and slidably mounted on the sliding mounting bracket 42. The sliding direction of the abutment rod 49 is the same as the sliding direction of the sliding mounting bracket 42. The end of the abutment rod 49 is in contact with the outer side wall of the cam 48. The abutment spring 50 is sleeved on the abutment rod 49. One end of the abutment spring 50 is fixedly connected to the sliding mounting bracket 42, and the other end of the abutment spring 50 is fixedly connected to the outer side wall of the abutment rod 49. An arc-shaped mounting bracket 51 is provided on the clamping mounting plate 35. The frame 51 is located outside the first arc-shaped claw 33 or the second arc-shaped claw 34. The clamping mounting plate 35 and the arc-shaped mounting frame 51 are elastically connected by an elastic connection device. Several sets of elastic connection devices are provided, and the sets of elastic connection devices are distributed in a ring around the arc center of the first arc-shaped claw 33 or the second arc-shaped claw 34. The elastic connection device includes a horizontal elastic rod 52 and a vibration spring 53. One end of the horizontal elastic rod 52 is fixedly connected to the outer wall of the first arc-shaped claw 33 or the second arc-shaped claw 34, and the other end of the horizontal elastic rod 52 is slidably connected to the arc-shaped mounting frame 51. The vibration spring 53 is sleeved on the horizontal elastic rod 52. One end of the vibration spring 53 is fixedly connected to the outer wall of the first arc-shaped claw 33 or the second arc-shaped claw 34, and the other end of the vibration spring 53 is fixedly connected to the inner wall of the arc-shaped mounting frame 51.

[0055] When the vibration drive assembly is working, the output of the second rotary driver 47 drives the cam 48 to rotate. The cam 48 drives the abutment rod 49, which is in contact with its surface, to push outward intermittently. At the same time, the abutment spring 50 can realize the reset function of the abutment rod 49, that is, to ensure that one end of the abutment rod 49 is always in contact with the outer surface of the cam 48, thereby realizing the reciprocating horizontal movement function of the abutment rod 49. The other end of the abutment rod 49 realizes the vibration drive operation of the second mounting cylinder 3, thereby realizing the vibration drive function of the fisheye lens.

[0056] When the vibration drive assembly drives the fisheye lens, the clamping mechanism 18 ensures that the fisheye lens can vibrate during clamping through an elastic connection device. The horizontal elastic rod 52 enables the arc-shaped mounting bracket 51 to mount the first arc-shaped claw 33 or the second arc-shaped claw 34. The vibration spring 53 enables the vibration transmission function. When vibration is not driven, the elastic forces of several vibration springs 53 cancel each other out, so that the semi-arc-shaped claw 31 is in the center position, thereby enabling accurate detection function.

[0057] The first contact block 25 is provided with a first contact inclined surface 54, and the second contact block 26 is provided with a second contact inclined surface 55 that cooperates with the first contact inclined surface 54. There are two of each of the first contact block 25 and the second contact block 26. The first contact block 25 is fixedly installed on the material handling robot 22, and the two second contact blocks 26 are respectively fixedly installed on two semi-circular grippers 31.

[0058] When the first contact block 25 and the second contact block 26 are in motion, the first contact block 25 presses down, and the first contact inclined surface 54 and the second contact inclined surface 55 cooperate, so that the second contact block 26 has a tendency to move outward. Then, the semi-circular gripper 31 deflects outward around the axis of the hinge rod 28, thereby realizing the opening function of the semi-circular gripper 31.

[0059] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
