Technical Field

[0001] This invention relates to the field of surveillance camera lens inspection technology, and in particular to a lens inspection device for surveillance camera manufacturing. Background Technology

[0002] During the manufacturing and assembly of surveillance cameras, the lens, as a core optical component, directly affects key indicators such as image clarity and field of view. Multiple optical parameters of the lens need to be tested during lens manufacturing and overall camera assembly.

[0003] Currently, the inspection process for surveillance camera lenses has the following main shortcomings: First, the existing testing equipment is not highly automated. Most testing steps still require manual clamping and positioning, resulting in high labor costs.

[0004] Secondly, existing testing devices lack efficient and stable automatic clamping mechanisms for lens clamping and positioning. When lenses need to be clamped and released during transport, traditional manual or semi-automatic clamping operations are cumbersome and inefficient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a lens inspection device for processing surveillance cameras. The clamping process is fast, stable and does not damage the lens surface, reduces the process of manual intervention, lowers labor costs, eliminates the inconsistency of manual operation, and can perform optical inspection on both sides of the lens at the same time without flipping the lens or setting up multiple processes, which greatly improves the inspection efficiency and can effectively solve the problems in the background technology.

[0006] To achieve the aforementioned objective, the present invention employs the following technical solution: A lens inspection device for surveillance camera processing includes a frame and an optical inspection instrument. A PLC controller is mounted on the side of the frame, and a chain conveyor is mounted on the inner side of the frame. Fixed seats are evenly fixed on the conveyor chain of the chain conveyor, and fixed clamps are fixed on the outer side of the fixed seats. Elastic clamping components are connected to the fixed seats corresponding to the positions of the fixed clamps through a transmission mechanism. A drive mechanism for driving the transmission mechanism is mounted on the frame. A position adjustment mechanism is mounted on the frame, and a detection box is fixed on the adjustment part of the position adjustment mechanism. There are two sets of detection boxes, which are symmetrically arranged vertically. The optical inspection instrument is mounted at the end of the detection box, and an illumination lamp is mounted at the end of the detection box. The optical inspection instrument, the illumination lamp, and the chain conveyor are all electrically connected to the PLC controller, and the PLC controller is electrically connected to an external power supply.

[0007] Furthermore, the transmission mechanism includes a guide rod and a sliding seat, the end of the guide rod being fixedly connected to a fixed seat, and the sliding seat being slidably connected to the guide rod.

[0008] Furthermore, the transmission mechanism also includes tooth grooves, a rotating shaft, and gears. The gears are rotatably mounted on the conveyor chain of the chain conveyor via the rotating shaft. The tooth grooves are evenly distributed on the side of the sliding seat, and the gears mesh with the tooth grooves. The drive mechanism is used to drive the rotating shaft to rotate.

[0009] Furthermore, the drive mechanism includes a socket and a plug, with the socket fixed to the end of the rotating shaft and the plug engaging with the socket.

[0010] Furthermore, the drive mechanism also includes an electric push rod and a first servo motor. There are two sets of electric push rods, which are symmetrically installed in the middle of the frame and are set to correspond to the loading and unloading positions of the chain conveyor. The first servo motor is installed at the telescopic end of the electric push rod, and the plug is fixed on the output shaft of the first servo motor. Both the electric push rod and the first servo motor are electrically connected to the PLC controller.

[0011] Furthermore, the elastic clamping assembly includes a movable clamp, a spring, and a movable rod. The movable rod is fixed to the side of the sliding seat and movably connected to the fixed seat. The movable clamp is fixed to the end of the movable rod and is correspondingly arranged with the fixed clamp. The spring is sleeved on the movable rod and is arranged between the movable clamp and the fixed seat.

[0012] Furthermore, the position adjustment mechanism includes a transmission seat and a guide rail. The end of the guide rail is fixedly connected to the frame, the transmission seat is slidably connected to the guide rail, and the detection box is fixed to the side of the transmission seat.

[0013] Furthermore, the position adjustment mechanism also includes a second servo motor and a bidirectional lead screw. The bidirectional lead screw is rotatably mounted on the inner side of the frame, the second servo motor is mounted on the top of the frame, the output shaft of the second servo motor is fixedly connected to the end of the bidirectional lead screw, the bidirectional lead screw is threadedly connected to the transmission seat, and the second servo motor is electrically connected to the PLC controller.

[0014] Furthermore, it also includes a sealing ring, which is disposed at the opening of the detection box.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The automatic transport of lenses is achieved through a chain conveyor, and the automatic opening and closing of the movable fixture is achieved through the cooperation of the drive mechanism and the transmission mechanism, which reduces the process of manual intervention, lowers labor costs, and eliminates the inconsistency of manual operation.

[0016] 2. By using a chain conveyor with a fixed base and clamps, continuous conveying and online inspection of lenses can be achieved. The two sets of inspection boxes are symmetrically arranged, allowing for simultaneous optical inspection of both sides of the lens. This eliminates the need to flip the lens or set up multiple processes, significantly improving inspection efficiency.

[0017] 3. Its elastic clamping component uses a spring to provide clamping force. When the drive mechanism moves the movable clamp away from the fixed clamp, the lens can be easily put in or taken out. After the drive mechanism is withdrawn, the spring automatically resets to achieve elastic clamping of the lens. The clamping process is fast, stable and does not damage the lens surface.

[0018] 4. The detection box opening is equipped with a sealing ring. When the two sets of detection boxes are fastened to both ends of the lens, the sealing ring can effectively block external light, provide a good dark box detection environment, avoid interference from external stray light on the detection results, and ensure detection accuracy and repeatability.

Detailed Implementation

[0021] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0022] Please see Figure 1-6 This embodiment provides a technical solution: a lens inspection device for processing surveillance cameras, including a frame 1 and an optical inspection instrument 12. A PLC controller 2 is installed on the side of the frame 1, and a chain conveyor 7 is installed on the inner side of the frame 1. Fixed seats 8 are evenly fixed on the conveyor chain of the chain conveyor 7, and fixed clamps 9 are fixed on the outer side of the fixed seats 8. An elastic clamping component 5 is connected to the fixed seat 8 at the position corresponding to the fixed clamp 9 through a transmission mechanism 3. A drive mechanism 6 for driving the transmission mechanism 3 is installed on the frame 1. A position adjustment mechanism 4 is installed on the frame 1. A detection box 11 is fixed on the adjustment part of the position adjustment mechanism 4. There are two sets of detection boxes 11, which are symmetrically arranged vertically. The optical inspection instrument 12 is installed at the end of the detection box 11, and an illumination lamp 13 is installed at the end of the detection box 11. The optical inspection instrument 12, the illumination lamp 13 and the chain conveyor 7 are all electrically connected to the PLC controller 2, and the PLC controller 2 is electrically connected to an external power supply.

[0023] The transmission mechanism 3 includes a guide rod 35 and a sliding seat 32. The end of the guide rod 35 is fixedly connected to the fixed seat 8, and the sliding seat 32 is slidably connected to the guide rod 35. The transmission mechanism 3 also includes a toothed groove 31, a rotating shaft 33, and a gear 34. The gear 34 is rotatably mounted on the conveyor chain of the chain conveyor 7 via the rotating shaft 33. The toothed groove 31 is evenly opened on the side of the sliding seat 32, and the gear 34 meshes with the toothed groove 31. The drive mechanism 6 is used to drive the rotating shaft 33 to rotate. The drive mechanism 6 includes a socket 63 and a plug 64. Fixed at the end of the rotating shaft 33, the plug 64 is inserted into the socket 63. The drive mechanism 6 also includes an electric push rod 61 and a first servo motor 62. There are two sets of electric push rods 61, which are symmetrically installed in the middle of the frame 1 and are set to correspond to the loading and unloading positions of the chain conveyor 7. The first servo motor 62 is installed at the telescopic end of the electric push rod 61. The plug 64 is fixed on the output shaft of the first servo motor 62. Both the electric push rod 61 and the first servo motor 62 are electrically connected to the PLC controller 2. The clamping assembly 5 includes a movable clamp 51, a spring 52, and a movable rod 53. The movable rod 53 is fixed to the side of the sliding seat 32 and movably connected to the fixed seat 8. The movable clamp 51 is fixed to the end of the movable rod 53 and is correspondingly arranged with the fixed clamp 9. The spring 52 is sleeved on the movable rod 53 and is arranged between the movable clamp 51 and the fixed seat 8. First, the telescopic end of the electric push rod 61 drives the first servo motor 62 to move, so that the plug 64 is inserted into the socket 63 at the end of the rotating shaft 33. Then, the PLC controller 2 controls the first... When the servo motor 62 starts, the output shaft of the first servo motor 62 drives the rotating shaft 33 to rotate. The rotating shaft 33 drives the gear 34 to rotate. The gear 34 meshes with the tooth groove 31 for transmission. The tooth groove 31 drives the sliding seat 32 to slide along the guide rod 35. The sliding seat 32 drives the movable clamp 51 away from the fixed clamp 9 through the movable rod 53. At this time, the fixed clamp 9 and the movable clamp 51 are opened. The operator can remove the lens that has been tested from the fixed clamp 9 and then place the lens to be tested between the fixed clamp 9 and the movable clamp 51.

[0024] Then, the PLC controller 2 controls the first servo motor 62 to reverse, the rotating shaft 33 to rotate, and at the same time, the telescopic end of the electric push rod 61 drives the plug 64 to separate from the socket 63. At this time, the spring 52 returns to its deformation, and the elastic force of the spring 52 acts on the movable clamp 51, pushing the movable clamp 51 to move towards the fixed clamp 9, thereby pressing the lens to be tested onto the fixed clamp 9 and completing the clamping and positioning of the lens.

[0025] Then, the PLC controller 2 controls the chain conveyor 7 to start, and the conveyor chain of the chain conveyor 7 moves forward one station, moving the fixed seat 8 with the lens clamped to the position of the detection box 11.

[0026] The position adjustment mechanism 4 includes a transmission seat 43 and a guide rail 44. The end of the guide rail 44 is fixedly connected to the frame 1, and the transmission seat 43 is slidably connected to the guide rail 44. The detection box 11 is fixed on the side of the transmission seat 43. The position adjustment mechanism 4 also includes a second servo motor 41 and a bidirectional lead screw 42. The bidirectional lead screw 42 is rotatably mounted on the inner side of the frame 1, and the second servo motor 41 is mounted on the top of the frame 1. The output shaft of the second servo motor 41 is fixedly connected to the end of the bidirectional lead screw 42. The bidirectional lead screw 42 is threadedly connected to the transmission seat 43. The second servo motor 41 is electrically connected to the PLC controller 2. It also includes a sealing ring 10, which is set at the opening of the detection box 11. The PLC controller 2 controls the second servo motor 41 to start. The output shaft of the second servo motor 41 drives the bidirectional lead screw 42 to rotate. The bidirectional lead screw 42 is threadedly driven to the transmission seat 43. The transmission seat 43 slides along the guide rail 44. The transmission seat 43 drives the two sets of detection boxes 11 to move towards each other until they are fastened to both ends of the lens. At this time, the sealing ring 10 at the opening of the detection box 11 is tightly attached to the lens surface, forming a dark box detection environment that isolates external light.

[0027] Then, PLC controller 2 controls one end of the illumination lamp 13 to light up and the other end of the illumination lamp 13 to turn off, while simultaneously controlling the optical inspection instrument 12 at that end to perform inspection. After the inspection is completed, PLC controller 2 controls the other end of the illumination lamp 13 to light up and the first end of the illumination lamp 13 to turn off, while simultaneously controlling the optical inspection instrument 12 at the other end to perform inspection. In this way, the optical performance of both sides of the lens can be inspected.

[0028] The working principle of the lens inspection device for surveillance camera processing provided by the present invention is as follows: First, the telescopic end of the electric push rod 61 drives the first servo motor 62 to move, so that the plug 64 is inserted into the socket 63 at the end of the rotating shaft 33. Then, the PLC controller 2 controls the first servo motor 62 to start. The output shaft of the first servo motor 62 drives the rotating shaft 33 to rotate. The rotating shaft 33 drives the gear 34 to rotate. The gear 34 meshes with the tooth groove 31 for transmission. The tooth groove 31 drives the sliding seat 32 to slide along the guide rod 35. The sliding seat 32 drives the movable clamp 51 away from the fixed clamp 9 through the movable rod 53. At this time, the fixed clamp 9 and the movable clamp 51 are opened. The operator can remove the lens that has been inspected from the fixed clamp 9 and then place the lens to be inspected between the fixed clamp 9 and the movable clamp 51.

[0029] Then, the PLC controller 2 controls the first servo motor 62 to reverse, the rotating shaft 33 to rotate, and at the same time, the telescopic end of the electric push rod 61 drives the plug 64 to separate from the socket 63. At this time, the spring 52 returns to its deformation, and the elastic force of the spring 52 acts on the movable clamp 51, pushing the movable clamp 51 to move towards the fixed clamp 9, thereby pressing the lens to be tested onto the fixed clamp 9 and completing the clamping and positioning of the lens.

[0030] The automatic transport of lenses is achieved by the chain conveyor 7, and the automatic opening and closing of the movable fixture 51 is achieved by the cooperation of the drive mechanism 6 and the transmission mechanism 3. This reduces the manual intervention process, lowers labor costs, and eliminates the inconsistency of manual operation. The chain conveyor 7, together with the fixed seat and fixture, enables continuous transport and online inspection of lenses. The two sets of inspection boxes 11 are symmetrically arranged, allowing for simultaneous optical inspection of both sides of the lens without the need to flip the lens or set up multiple processes, which greatly improves the inspection efficiency.

[0031] Its elastic clamping component 5 uses spring 52 to provide clamping force. When the drive mechanism 6 drives the movable clamp 51 away from the fixed clamp 9, the lens can be easily put in or taken out. After the drive mechanism 6 is withdrawn, the spring 52 automatically resets to achieve elastic clamping of the lens. The clamping process is fast, stable and does not damage the lens surface.

[0032] Then, the PLC controller 2 controls the chain conveyor 7 to start, and the conveyor chain of the chain conveyor 7 moves forward one station, moving the fixed seat 8 with the lens clamped to the position of the detection box 11.

[0033] Then, the PLC controller 2 controls the second servo motor 41 to start. The output shaft of the second servo motor 41 drives the bidirectional lead screw 42 to rotate. The bidirectional lead screw 42 is threadedly driven by the transmission seat 43. The transmission seat 43 slides along the guide rail 44, and the transmission seat 43 drives the two sets of detection boxes 11 to move towards each other until they are fastened to both ends of the lens. At this time, the sealing ring 10 at the opening of the detection box 11 is tightly attached to the lens surface, forming a dark box detection environment that isolates external light.

[0034] Then, PLC controller 2 controls one end of the illumination lamp 13 to light up and the other end of the illumination lamp 13 to turn off, while simultaneously controlling the optical inspection instrument 12 at that end to perform inspection. After the inspection is completed, PLC controller 2 controls the other end of the illumination lamp 13 to light up and the first end of the illumination lamp 13 to turn off, while simultaneously controlling the optical inspection instrument 12 at the other end to perform inspection. In this way, the optical performance of both sides of the lens can be inspected.

[0035] After the inspection is completed, the PLC controller 2 controls the second servo motor 41 to reverse, and the two sets of inspection boxes 11 move away from each other and separate. The chain conveyor 7 continues to convey forward, transporting the inspected lens to the unloading position, and at the same time, transporting the next lens to be inspected to the inspection station, and entering the next round of inspection cycle.
