At the same time, the stability of the material tray in the receiving groove during movement and the stability of the lenses in each material tray during movement are also ensured. The present invention is efficient and convenient.

[0018] (4) The present invention arranges a dynamic vibration absorber between the loading bottom plate and the receiving bottom plate. When the loading bottom plate vibrates during use, the vibration absorber drives the mass block to vibrate together. Since the natural frequency of the dynamic vibration absorber is close to or equal to the vibration frequency of the loading bottom plate, the dynamic vibration absorber will produce a large vibration displacement at this time, and the reaction force generated by this displacement will act on the loading bottom plate in the opposite direction to the vibration direction of the loading bottom plate, thereby offsetting the vibration energy of the loading bottom plate, thereby reducing the vibration of the loading bottom plate, and further ensuring the stability of the loading bottom plate and the receiving bottom plate during movement. The present invention is convenient and practical.

[0019] (5) The present invention further effectively ensures the stability of the loading base plate during movement by arranging at least two vertically arranged dynamic vibration absorbers on the loading base plate. At the same time, a counterweight plate is arranged on the upper end surface or side surface of the mass block, which effectively ensures the high efficiency of the mass block in absorbing vibration of the loading base plate, and has good adjustability and applicability.

[0020] (6) The present invention sequentially photographs and detects the upper and lower end surfaces of the lenses in the tray by configuring the first photographing component to cooperate with the first photographing camera and the second photographing camera, and ensures the stability of the first photographing camera and the second photographing light source, as well as the second photographing camera and the second photographing light source during the lifting and moving process through the cooperation of the third linear module and the fourth linear module. By configuring the second photographing component, the fifth linear module on the second photographing component drives the third lifting plate, so that each OCT camera comprehensively photographs the lenses. The first photographing camera, the second photographing camera, and the OCT camera comprehensively and efficiently photograph and detect the lenses, thereby ensuring the accuracy and efficiency of the photographing and detecting of the lenses, and being convenient and practical.

[0021] (7) The present invention sets a second linear module on the shooting bracket, and drives the movable plate through the second linear module to switch between the backup camera and the first shooting camera. The first shooting camera can be disassembled and replaced without delaying the shooting of the lens, or by switching between the first shooting camera and the backup camera, lenses of different sizes can be used, and lenses of different sizes can be shot and focused. The present invention has good applicability and adjustability.

[0022] (8) The present invention arranges two transfer devices on the unloading frame. The transfer devices can transfer the material trays on the loading bottom plate to the buffer platform, and then transfer the lenses in the material trays on the buffer platform to the material trays on the unloading platform. Through the cooperation of the transfer devices, it can effectively ensure that the material trays after shooting are transferred to the buffer platform in an orderly, efficient and accurate manner, and the lenses can be accurately sorted and unloaded according to the shooting results, which is efficient and convenient.

[0023] (9) The present invention arranges positioning components on the buffer platform and the unloading platform. After the second positioning block slides, one side of the material tray is pressed against the first limit block. After the third positioning block slides, the other side of the material tray is pressed against the second limit block. On the one hand, the stability of the material tray is ensured, and on the other hand, the accuracy of each lens when entering the material tray is ensured. The present invention is stable and practical.

[0024] (10) The present invention arranges a bottom shock-absorbing pad between the connecting bottom plate and the supporting bottom plate to ensure the stability of the transplanting device and the unloading device during movement, and reduces the vibration of the transplanting device and the unloading device through the bottom shock-absorbing pad. By setting the first working platform and the shooting bracket to be made of marble material, the strong rigidity and low-frequency vibration absorption ability of marble can be used to reduce the influence of the loading device and the detection device on the OCT detection during operation. At the same time, the first shock-absorbing pad and the shock-absorbing washer greatly reduce the vibration between the first frame and the first working platform, which is convenient and practical.

[0037] Working principle of the present invention: During the use of the present invention, the shooting bracket 3 made of marble is installed on the first working platform 2 made of marble, and the strong rigidity and low-frequency vibration absorption ability of marble are used to reduce the influence of the movement of the loading bottom plate 42 on the OCT detection during the detection. The first working platform 2 is installed on the first frame 1 through the installation component 13. During the installation process, the first shock-absorbing pad 132 and the shock-absorbing washer 135 can perform shock isolation treatment on the first frame 1 and the first working platform 2, which greatly reduces the vibration of the first working platform 2 during operation. The second working platform 21 is installed on the second frame 11, and the bottom shock-absorbing pad 26 between the connecting bottom plate 25 and the supporting bottom plate 27 can effectively shock-absorb and buffer the vibration of the second working platform 21 on the second frame 11; During the loading process, the operator can place the material tray filled with lenses in each receiving groove 441 on the receiving base plate 44. During the loading process, one of the two loading devices 4 feeds the material through the driving of the bottom linear module 41 and the cooperation of the first slider 47 and the first slide rail 46. The receiving base plate 44 and the side plates 45 on both sides of the receiving base plate 44 are driven by the first linear module 43 and the cooperation of the second slider 49 and the second slide rail 48 to move the material tray in the receiving groove 441 toward the first camera 53 and the second camera 58. Each lens in the loading tray of the receiving base plate 44 is first transferred to the bottom of the first camera 53 by the driving of the first linear module 43. The first camera 53 is driven by The upper end faces of each lens on the tray are photographed and detected in coordination with the first shooting light source 54. After the upper end faces of each lens on the tray are photographed, each lens in the tray on the receiving bottom plate 44 is driven by the first linear module 43 and transferred to the top of the second shooting camera 58. The second shooting camera 58 photographs and detects the lower end faces of each lens by cooperating with the second shooting light source 59. At the same time, another loading device 4 transfers the tray on the receiving bottom plate 44 to the second shooting component 6 by driving the bottom linear module 41. The two OCT cameras 63 drive the third lifting plate 62 by the fifth linear module 61 and drive the receiving bottom plate 44 by the first linear module 43 to perform rhythmic and orderly photography and detection of the tray. After the first camera 53 and the second camera 58 on the first shooting component 5 successively shoot and detect the various material trays on the receiving bottom plate 44 of a loading device 4, the loading device 4 moves to the second shooting component 6, and the second shooting component 6 is arranged in the middle part of the shooting bracket 3. At the same time, another loading device 4 that has completed shooting at the second shooting component 6 starts to move toward the first shooting component 5. After the 2D shooting at the first shooting component 5 is completed, the material tray moves to the second shooting component 6 for OCT shooting. At the same time, the material tray located at the second shooting component 6 for OCT shooting is transferred to the first shooting component 5 for 2D shooting. Through the staggered shooting of the two loading devices 4, on the one hand, the efficiency and quality of shooting of each lens of the material tray can be improved. On the other hand, compared with the traditional 2D shooting and OCT shooting in sequence on the same production line, the efficiency of shooting of each lens can be greatly saved by setting two loading devices 4. During the movement of each loading bottom plate 42, a dynamic vibration absorber 9 is arranged between the loading bottom plate 42 and the receiving bottom plate 44. During the use of the vibration absorber 9, when the loading bottom plate 42 vibrates, the mass block 94 is driven to vibrate together. Since the natural frequency of the dynamic vibration absorber 9 is close to or equal to the vibration frequency of the loading bottom plate 42, the dynamic vibration absorber 9 will produce a large vibration displacement at this time, and the reaction force generated by this displacement will act on the loading bottom plate 42 in the opposite direction of the vibration of the loading bottom plate 42, thereby offsetting the vibration energy of the loading bottom plate 42, thereby reducing the vibration of the loading bottom plate 42, and further ensuring the stability of the loading bottom plate 42 and the receiving bottom plate 44 during the movement; After the 2D shooting and OCT shooting of the lenses in the material trays of each loading device 4 are completed, the two mechanical arms 71 on the transfer device 7 and the tray-taking assembly 75 on the mechanical arm 71 transfer the various material trays on the receiving bottom plate 44 to the various positioning assemblies 8 on the buffer platform 22, and the second positioning block 83 slides to press one side of the material tray against the first limit block 822, and the third positioning block 84 slides to press the other side of the material tray against the second limit block 821, and the two mechanical arms 71 on the transfer device 7 and the film-taking assembly 74 on the mechanical arm 71 transfer the various lenses in the material trays on the buffer platform 22. After the lenses in the material trays on the buffer platforms 22 are removed and sorted, the two mechanical arms 71 on the transfer device 7 and the tray removal assembly 75 on the mechanical arm 71 transfer the material trays on the buffer platforms 22 to the material unloading slots 24 and put them into the material unloading drawer 16, thereby realizing the unloading of the material trays and the sorting of the lenses. After the lenses in the material trays of the positioning assemblies 8 in the qualified and unqualified areas are full, the operator removes the material trays, thereby realizing the unloading of the lenses after the inspection is completed. The present invention has an ingenious structure and can effectively solve the problems of low detection quality and poor detection efficiency in the prior art. The lenses in the tray are automatically photographed in 2D and OCT, and the tray and lenses after the photography and detection are completed are automatically transferred, sorted and unloaded, which greatly improves the efficiency and quality of loading, transferring, sorting and unloading the tray and each lens in the tray. The structure is ingenious and the material is stable and practical.
