Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, in particular to a turntable detection platform and lens detection equipment. Background Art

[0002] Optical components such as large-diameter lenses often have some appearance defects during the production process (such as grinding or polishing), such as scratches, dents, cracks, edge collapse and other surface defects; if these defective lenses are used, it will have a great impact on the visual experience achieved, so it is necessary to use accurate and efficient methods to detect the defects of large-diameter lenses.

[0003] At present, the appearance inspection of existing large-diameter lenses is usually judged by manual visual inspection. However, as the demand for products increases, the disadvantages of traditional manual visual inspection are becoming more and more obvious, mainly reflected in: the lens is easily contaminated during the inspection process, making it impossible to ensure the cleanliness of the lens; the inspection efficiency is low; the accuracy of the inspection results will be seriously affected by human subjective factors; the manual inspection process is affected by subjective improper operation, causing lens damage, etc. Therefore, manual visual inspection is no longer suitable for large-diameter lens appearance inspection with large quantities and high precision.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

Unless it is clearly indicated in the disclosure of the present invention that the number of the element is only one, the term "one" cannot be understood as unique or single, and the term "one" cannot be understood as a limitation on the quantity.

[0055] In the description of the present utility model, it should be understood that "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through a medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0056] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0057] Considering that as the demand for products increases, the disadvantages of traditional manual visual inspection become more and more obvious, and it is no longer suitable for large-scale, high-precision appearance inspection of large-diameter lenses. The present application provides a turntable inspection platform and lens inspection equipment, which can perform fully automatic inspection of large-diameter lenses while ensuring that the lenses remain clean and uncontaminated during the inspection process.

[0058] Specifically, refer to the accompanying drawings of the specification of this application. Figures 1 to 16 According to one embodiment of the present application, a lens inspection device 1 is provided, which may include a cover assembly 10 for providing a clean environment, a turntable inspection platform 20 disposed in the cover assembly 10, a loading assembly 30 for automatically loading materials to the turntable inspection platform 20, and a unloading assembly 40 for automatically unloading materials from the turntable inspection platform 20. In this way, the lens product W to be inspected is placed in the turntable inspection platform 20 through the loading assembly 30, so that the turntable inspection platform 20 automatically inspects the lens product W in a clean environment, and then the unloading assembly 40 takes out the inspected lens product W from the turntable inspection platform 20. It can be understood that the lens product W mentioned in the present application can be, but is not limited to, implemented as a large-diameter lens.

[0059] More specifically, if Figures 3 to 8 As shown, the turntable inspection platform 20 may include a turntable rotating assembly 21, a plurality of magnetic wheel carriers 22 for carrying the lens product W, a plurality of magnetic drive assemblies 23, and a visual inspection assembly 24. The turntable rotating assembly 21 has a circumferentially arranged loading station 2101, an inspection station 2102, and a unloading station 2103. A plurality of the magnetic wheel carriers 22 are circumferentially arranged on the turntable rotating assembly 21, and each of the magnetic wheel carriers 22 is rotatably disposed on the turntable rotating assembly 21, so as to sequentially pass through the loading station 2101, the inspection station 2102, and the unloading station 2103 under the drive of the turntable rotating assembly 21, thereby sequentially transporting the lens product W to the loading station 2101, the inspection station 2102, and the unloading station 2103. The plurality of magnetic drive components 23 are respectively located at the loading station 2101, the inspection station 2102 and the unloading station 2103, and each magnetic drive component 23 can be magnetically connected to the magnetic wheel carrier 22 at the corresponding station to drive the magnetic wheel carrier 22 to rotate relative to the turntable rotating component 21 at the corresponding station, so as to adjust the azimuth angle of the lens product W carried by the magnetic wheel carrier 22. The visual inspection component 24 is located at the corresponding inspection station 2102, and is used to perform defect inspection on the lens product W carried by the magnetic wheel carrier 22 at the corresponding inspection station 2102.

[0060] It is worth noting that dust pollution has always been the biggest "enemy" of the lens industry's production and manufacturing. Even if the lens product W is tested in a clean environment, the lens product W needs to rotate during the testing process to meet the lens azimuth requirements of a specific workstation. The existing solution is usually to fix the driver on a turntable and drive it to the carrier through a belt or gear drive. This direct contact transmission method will cause friction during the transmission process and inevitably generate dust particles, which will still cause dust pollution.

[0061] However, the turntable detection platform 20 of the present application is contactlessly driven by magnetic drive, so that there is no contact between the magnetic drive component 23 and the magnetic wheel carrier 22, and there is no contact friction, which greatly reduces the generation of dust particles during the transmission process, which is beneficial to improving the cleanliness of the detection equipment. At the same time, the magnetic drive component 23 does not need to be installed on the turntable like traditional mechanical drive mechanisms such as belt drive or chain drive, but only needs to be arranged below the turntable rotating component 21, which greatly reduces the rotational inertia of the turntable rotating component 21, which is beneficial to reduce the drive power requirements of the turntable rotating component 21, and is convenient for improving the rotation positioning accuracy, reducing costs, and improving feasibility.

[0062] Preferably, if Figure 3 and Figure 4 As shown, the number of the inspection stations 2102 in the turntable rotating assembly 21 can be multiple, and correspondingly, the number of the visual inspection components 24 is also multiple, and they correspond one to one with the inspection stations 2102. In this way, the multiple visual inspection components 24 can simultaneously and parallelly inspect different appearance defect indicators of the lens product W at the corresponding inspection stations 2102, greatly improving the inspection efficiency. For example, the number of the inspection stations 2102 can be five, and the different indicators of the lens product W are inspected by five visual inspection components 24 respectively.

[0063] For example, Figures 5 to 8 As shown, the magnetic wheel carrier 22 may include a lens fixture 221 for releasably clamping the lens product W, a bearing 222 for rotatably connecting the lens fixture 221 to the turntable rotating assembly 21, and a driven magnetic wheel 223 fixedly connected to the lens fixture 221. In this way, the driven magnetic wheel 223 can drive the lens fixture 221 to rotate relative to the turntable rotating assembly 21 under the magnetic drive of the magnetic drive assembly 23 to change the azimuth angle of the lens product W clamped by the lens fixture 221. For example, Figure 7 As shown, the bearing 222 mentioned in the present application may be implemented as a cross roller bearing but is not limited to it.

[0064] Alternatively, if Figure 5As shown, the magnetic drive assembly 23 includes an active magnetic wheel 231 matched with the driven magnetic wheel 223, a telescopic cylinder 232 drivingly connected to the active magnetic wheel 231, and a rotating motor 233 drivingly connected to the active magnetic wheel 231; the active magnetic wheel 231 is driven by the telescopic cylinder 232 to approach or move away from the driven magnetic wheel 223 to move between a magnetic coupling position and a magnetic decoupling position. It can be understood that when the active magnetic wheel 231 is driven by the telescopic cylinder 232 to approach the driven magnetic wheel 223 to move to the magnetic coupling position, the magnetic force generated between the active magnetic wheel 231 and the driven magnetic wheel 223 increases, so that the driven magnetic wheel 223 can rotate with the rotation of the active magnetic wheel 231; when the active magnetic wheel 231 is driven by the telescopic cylinder 232 to move away from the driven magnetic wheel 223 to move to the magnetic decoupling position, the magnetic force generated between the active magnetic wheel 231 and the driven magnetic wheel 223 is greatly reduced, so that the driven magnetic wheel 223 will not rotate with the rotation of the active magnetic wheel 231.

[0065] In this way, when the azimuth angle of the lens product W needs to be adjusted to meet the requirements of material placement or visual inspection, the telescopic cylinder 232 drives the active magnetic wheel 231 to approach the driven magnetic wheel 223 to move to the magnetic coupling position; at this time, the rotating motor 233 drives the active magnetic wheel 231 to rotate to magnetically drive the driven magnetic wheel 223 to rotate relative to the turntable rotating component 21, thereby driving the lens fixture 221 to rotate relative to the turntable rotating component 21 to achieve the azimuth angle adjustment of the lens product W; when the azimuth angle adjustment is completed, the turntable needs to be rotated. When the component 21 rotates to transport the lens product W to the next workstation, the telescopic cylinder 232 drives the active magnetic wheel 231 away from the driven magnetic wheel 223 to move to the magnetic decoupling position; at this time, when the turntable rotating component 21 rotates to transport the magnetic wheel carrier 22 carrying the lens product W to the next workstation, the driven magnetic wheel 223 will not be deflected under the magnetic force of the active magnetic wheel 231, so as to ensure that the azimuth angle of the lens product W relative to the turntable rotating component 21 remains unchanged, which is conducive to the precise positioning of the lens product W.

[0066] It is worth noting that during the entire magnetic driving process, a gap is left between the active magnetic wheel 231 and the driven magnetic wheel 223, so there is no direct contact and no friction, which can effectively avoid dust generated by friction between the transmission wheels and contamination of the lens product W.

[0067] Alternatively, if Figure 5 and Figure 6As shown, the magnetic wheel carrier 22 further includes a sensor sensing piece 224; the magnetic drive assembly 23 further includes a position sensor 234 matched with the sensor sensing piece 224, which is used to detect the distance from the sensor sensing piece 224, so as to accurately position the active magnetic wheel 231 by the cooperation between the position sensor 234 and the sensor sensing piece 224, thereby ensuring that the active magnetic wheel 231 accurately moves to the magnetic coupling position or the magnetic decoupling position. It can be understood that the sensor sensing piece 224 is arranged adjacent to the driven magnetic wheel 223, and the position sensor 234 is arranged adjacent to the active magnetic wheel 231, so as to detect the distance between the driven magnetic wheel 223 and the active magnetic wheel 231; in other examples of the present application, the positions of the sensor sensing piece 224 and the position sensor 234 can be interchanged, and this application will not repeat them.

[0068] Optionally, when the active magnetic wheel 231 moves to the magnetic coupling position, the gap between the active magnetic wheel 231 and the driven magnetic wheel 223 is between 1 mm and 4 mm, so as to ensure that the driven magnetic wheel 223 can be stably magnetically driven by the active magnetic wheel 231 while ensuring that the magnetic wheels are not in direct contact.

[0069] Alternatively, if Figure 5 As shown, the active magnetic wheel 231 in the magnetic drive assembly 23 is coaxially connected to the output shaft of the rotating motor 233, so that the rotating motor 233 drives the active magnetic wheel 231 to rotate; the motor seat of the rotating motor 233 is fixedly connected to the telescopic rod of the telescopic cylinder 232, so that the rotating motor 233 and the active magnetic wheel 231 are synchronously driven to translate through the telescopic cylinder 232. It can be understood that in other examples of the present application, the telescopic rod of the telescopic cylinder 232 can also be directly connected to the active magnetic wheel 231, and the rotating motor 233 synchronously drives the telescopic cylinder 232 and the active magnetic wheel 231 to rotate, and this application will not repeat it.

[0070] In the above example of the present application, Figures 6 to 8 As shown, the lens jig 221 in the magnetic wheel carrier 22 may include a jig fixing base 2211 fixedly connected to the driven magnetic wheel 223, a pair of jig opening and closing pieces 2212 rotatably arranged on the jig fixing base 2211, and a pair of resetting members 2213 correspondingly arranged between the jig opening and closing pieces 2212 and the jig fixing base 2211. The two jig opening and closing pieces 2212 are closed to each other under the resetting action of the resetting members 2213 to clamp the lens product W placed therein, which can effectively prevent the lens product W from shaking under the centrifugal force of the turntable rotating assembly 21, and prevent the lens product W from rubbing against the jig to generate dust, thereby ensuring the imaging effect of the lens product W when it arrives at the detection station 2102.

[0071] Alternatively, if Figure 8 As shown, the reset member 2213 may be composed of a spring 22131 and a top screw 22132, and the top screw 22132 is screwed into the fixture fixed base 2211 to press the spring 22131 against the fixture opening and closing piece 2212 to provide a clamping force to reset the fixture opening and closing piece 2212. It is understandable that the clamping force of the fixture opening and closing piece 2212 can be controlled by the screwing length of the top screw 22132.

[0072] Alternatively, if Figure 4 and Figure 6 As shown, the turntable detection platform 20 may further include a thrust assembly 25, which is located at the loading station 2101 and the unloading station 2103, so as to push the fixture opening and closing pieces 2212 of the lens fixture 221 located at the corresponding station in a retractable manner. In this way, when the thrust assembly 25 pushes the fixture opening and closing pieces 2212, the two fixture opening and closing pieces 2212 are opened to take and place the lens product W; when the thrust assembly 25 retreats to move away from the fixture opening and closing pieces 2212, the two fixture opening and closing pieces 2212 are reset under the action of the reset member 2213 to clamp the lens product W placed therein.

[0073] Alternatively, if Figure 8 As shown, the fixture fixing base 2211 in the lens fixture 221 may include an annular seat body 22111 and a plurality of supporting blocks 22112 protruding from the inner wall of the annular seat body 22111 at intervals, and the upper surface of the supporting block 22112 extends obliquely downward from the outside to the inside to form a tapered supporting surface 22113 for supporting the lens product W, so that the tapered supporting surface 22113 only contacts the outer edge of the lens product W to play a bearing role, effectively avoiding direct contact between the optical surface of the lens product W and the lens fixture 221, thereby preventing damage or contamination of the optical surface of the lens product W.

[0074] According to the above embodiments of the present application, Figure 3 and Figure 4 As shown, the turntable rotating component 21 may further have a pair of dust removal stations 2104, which are respectively located between the loading station 2101 and the inspection station 2102 and between the inspection station 2102 and the unloading station 2103; accordingly, the turntable inspection platform 20 may further include a pair of dust removal components 26, and the two dust removal components 26 are respectively located at the dust removal stations 2104, so as to remove dust from the lens product W before and after the inspection, so as to ensure that the lens product W maintains a good cleanliness during and after the inspection, and improve the inspection accuracy and the accuracy of the inspection data.

[0075] Optionally, the dust removal component 26 can be implemented as an ultrasonic dry dust collector, but is not limited to it. It can be understood that the dust removal station 2104 located between the loading station 2101 and the inspection station 2102 performs dust removal on the lens product W before inspection, and its purpose is to clean the incoming materials of the lens product W, to ensure that the lens product W remains clean when entering the inspection station 2102, and to avoid cross contamination of the visual inspection component 24 or other clean lenses due to contamination of some lenses when they are incoming; the dust removal station 2104 located between the inspection station 2102 and the unloading station 2103 performs dust removal on the lens product W after inspection, and its purpose is to complete the closed-loop feedback of the inspection process of the lens product W, and improve the data accuracy of equipment inspection and manual calibration.

[0076] Alternatively, if Figure 4 As shown, the turntable rotating assembly 21 may include a turntable 211 providing the loading station 2101, the inspection station 2102, the unloading station 2103 and the dust removal station 2104, and a rotary motor 212 drivingly connected to the turntable 211; a plurality of magnetic wheel carriers 22 are evenly distributed on the turntable 211 in the circumferential direction, and the visual inspection assembly 24, the thrust assembly 25 and the dust removal assembly 26 are arranged around the turntable 211 and correspond to the loading station 2101, the inspection station 2102, the unloading station 2103 and the dust removal station 2104 respectively. It can be understood that the loading assembly 30 is arranged at the loading station of the turntable rotating assembly 21 for automatically loading the turntable inspection platform 20; the unloading assembly 40 is arranged at the unloading station of the turntable rotating assembly 21 for automatically unloading the turntable inspection platform 20.

[0077] According to the above embodiments of the present application, Figure 1 and Figure 2 As shown, the hood assembly 10 in the lens inspection device 1 may include a hood body 11 that covers the turntable inspection platform 20, the loading assembly 30, and the unloading assembly 40, an air filter 12 disposed on the top of the hood body 11, and a draught fan 13 disposed at the bottom of the hood body 11; the air intake of the air filter 12 is greater than the air output of the draught fan 13, so that the internal air pressure of the hood assembly 10 is always maintained at a positive pressure, thereby providing a clean microenvironment for the operation of the equipment, so as to provide cleanliness protection for the entire process of loading and unloading and inspection. It is understandable that the air filter 12 of the present application can be, but is not limited to, implemented as a blower with a filter screen to actively input clean air from the top of the hood body 11, and then the internal air is guided out from the bottom of the hood body 11 under the action of the draught fan 13.

[0078] Alternatively, if Figure 2As shown, a plurality of the exhaust fans 13 are evenly arranged on the peripheral side walls of the cover body 11 so as to form a uniform and smooth air flow field inside the cover body 11, thereby ensuring that the lens product W always maintains a high degree of cleanliness during the detection process.

[0079] Alternatively, if Fig. 9 and Fig.13 As shown, the loading assembly 30 may include a silo lifting assembly 31, a material box transport assembly 32, an opening and closing cover assembly 33 and a material picking and placing assembly 34 for connecting with the intelligent logistics vehicle; the material box transport assembly 32 is arranged between the silo lifting assembly 31 and the material picking and placing assembly 34, and is used to transport the material box containing the lens product W from the silo lifting assembly 31 to the material picking and placing assembly 34; the opening and closing cover assembly 33 is arranged on the transportation path of the material box transport assembly 32, and is used to open and close the cover of the material box transported by the material box transport assembly 32, so that the material picking and placing assembly 34 can subsequently take out the lens product W from the material box. In this way, when the intelligent logistics vehicle places the upper bin containing the material box on the material bin lifting component 31, the material bin lifting component 31 can adjust the position of the upper bin by lifting the height, so that the material box transport component 32 can smoothly take out the material box from the upper bin to transport it to the opening and closing cover component 33 to perform the opening action, and then transport the opened material box to the material taking and placing component 34 through the material box transport component 32, so as to take out the lens product W from the material box; after that, the material box transport component 32 transports the empty material box to the opening and closing cover component 33 to perform the closing action, and then transports it back to the upper bin. It can be understood that the opening and closing cover component 33 of the present application can automatically open and close the cover in a clean environment (i.e., a dust-free environment), effectively avoiding the risk of the lens product W being exposed to the air and contaminated. In addition, the intelligent logistics vehicle mentioned in the present application can be implemented as an automatic transport vehicle AGV, but is not limited to it.

[0080] For example, Fig.10 As shown, the silo lifting assembly 31 may include a silo lifting shaft 311, a silo clamping mechanism 312 drivingly connected to the silo lifting shaft 311, a steel ball roller 313 arranged on the silo clamping mechanism 312, a lateral tightening mechanism 314 correspondingly arranged on the silo clamping mechanism 312, and a guide wheel 315 arranged on the silo clamping mechanism 312. In this way, when the factory AGV transports the upper silo to the silo lifting shaft 311, the guide wheel 315 guides the upper silo, and when the upper silo is guided to the right position, the silo clamping mechanism 312 clamps the upper silo, and laterally tightens the upper silo through the lateral tightening mechanism 314 to accurately position it; at the same time, the steel ball roller 313 can reduce the friction of the upper silo during the positioning and tightening process.

[0081] Alternatively, if Fig.11As shown, the material box transport assembly 32 includes a material box carriage 321 for supporting the material box, a transport mechanism 322 drivingly connected to the material box carriage 321 , a clamping cylinder 323 disposed on the material box carriage 321 , and a positioning pin 324 correspondingly disposed on the material box carriage 321 . In this way, when the silo lifting assembly 31 drives the upper silo to rise and fall and adjust to the set position, the material box slide 321 extends into the upper silo under the drive of the conveying mechanism 322; then, the silo lifting assembly 31 drives the upper silo to descend until the material box in the upper silo is completely in contact with the material box slide 321, and at this time, the positioning pin 324 enters the characteristic hole of the material box; thereafter, the clamping cylinder 323 extends out to interact with the positioning pin 324 to clamp the material box, so that under the action of the conveying mechanism 322, the material box is successively consigned to the opening and closing cover assembly 33 and the material taking and placing assembly 34; finally, when all the lens products W in the material box are taken out, the empty material box is consigned to the upper silo along the original route under the action of the conveying mechanism 322.

[0082] Alternatively, if Fig.12 As shown, the opening and closing cover assembly 33 includes a plurality of suction nozzles 331 for sucking the lens product W, a suction nozzle fixing plate 332 for fixing the suction nozzles 331 , and a suction nozzle lifting module 333 drivingly connected to the suction nozzle fixing plate 332 . When the material box transport assembly 32 transports the material box to the opening and closing cover assembly 33, the suction nozzle lifting module 333 drives the suction nozzle fixing plate 332 to move downward, so that multiple suction nozzles 331 simultaneously descend to contact the upper cover of the material box to suck the upper cover; at this time, the suction nozzle lifting module 333 drives the suction nozzle fixing plate 332 to move upward, so that the suction nozzle 331 sucks up the upper cover to complete the automatic opening of the material box; when the empty material box returns to the opening and closing cover assembly 33, the suction nozzle lifting module 333 drives the suction nozzle fixing plate 332 to descend until the upper cover is completely in contact with the material box body, at this time, multiple suction nozzles 331 simultaneously put down the upper cover and reset upward under the action of the suction nozzle lifting module 333, completing the automatic closing of the material box.

[0083] Alternatively, if Fig.13As shown, the material taking and placing assembly 34 includes a lens taking and placing mechanism 341 for taking and placing the lens product W and a three-axis linear motion mechanism 342 drivingly connected to the lens taking and placing mechanism 341. In this way, the three-axis linear motion mechanism 342 can drive the lens taking and placing mechanism 341 to translate in three directions of the X-axis, the Y-axis and the Z-axis, so as to take out the lens products W placed vertically in a row in the material box one by one through the lens taking and placing mechanism 341, and place them horizontally in the next station. At the same time, the lens taking and placing mechanism 341 can also take out the horizontally placed lens products from the lens fixture 221 of the unloading station 2103 after the lens detection is completed, adjust them to a vertical state, and place them in the unloading assembly 40 according to different detection results. It can be understood that the material taking and placing assembly 34 of the present application is shared in the loading process and the unloading process, so as to improve compactness, save space and reduce costs.

[0084] Alternatively, if Fig.14 As shown, the lens picking and placing mechanism 341 includes a lens clamp 3411 for clamping the lens product W, a clamp pad 3412 provided on the lens clamp 3411, and a rotating mechanism 3413 drivingly connected to the lens clamp 3411; the clamp pad 3412 is a rubber part with Teflon coated on the surface. In this way, the clamp pad 3412 combines the softness of rubber with the non-stickiness of Teflon, which can not only prevent the lens clamp 3411 from causing secondary damage to the lens product W during the process of clamping the lens, but also reduce the adsorption of microparticles, and prevent cross contamination between lenses during the clamping process. It can be understood that the lens product W is placed vertically in the material box and placed horizontally during the detection process, and the rotating mechanism 3413 of the present application can drive the lens clamp 3411 to rotate so that the clamped lens product can switch between the vertical state and the horizontal state to meet different placement requirements.

[0085] It is worth noting that the structure of the unloading assembly 40 is basically similar to that of the loading assembly 30, except that: the unloading assembly 40 does not include the pick-up and placement assembly 34, but shares the pick-up and placement assembly 34 with the loading assembly 30; the unloading assembly 40 may have two sets, one set of unloading assembly 40 is used to carry the material box containing qualified products (hereinafter referred to as qualified product material box), and the other set of unloading assembly 40 is used to carry the material box containing unqualified products (hereinafter referred to as unqualified product material box). It can be understood that the pick-up and placement assembly 34 can put the lens products W that have been tested into the qualified product material box and the unqualified product material box respectively according to the test results, and then place the filled material box into the corresponding unloading bin (including the qualified unloading bin and the unqualified unloading bin) through the unloading assembly 40, and take out a new material box to receive the lens products taken out by the pick-up and placement assembly 34; when the unloading bin is completely full, the factory AGV can automatically connect the unloading.

[0086] According to the above embodiments of the present application, Figure 1 , Figure 2 as well as Fig.15 As shown, the lens inspection device 1 may further include a transfer inspection component 50 disposed between the loading component 30 and the turntable inspection platform 20, and the transfer inspection component 50 may include a transfer transmission mechanism 51 for transferring the lens product W, a code scanning mechanism 52 for scanning the lens product W, a material throwing mechanism 53 for discarding lens products that fail to pass the code scanning, a pre-detection positioning mechanism 54 for pre-detecting the position of the lens products that pass the code scanning, and a carrier for detecting the position of the lens fixture 221 at the loading station. Positioning mechanism 55; the transfer transmission mechanism 51 is used to first transfer the lens product W from the loading and unloading assembly 34 to the scanning mechanism 52 for lens scanning processing, and then according to the scanning result, transfer the lens product that passes the scanning to the pre-inspection positioning mechanism 54 for orientation detection, and based on the orientation of the lens fixture 221 detected by the carrier positioning mechanism 55, the lens product is accurately placed on the lens fixture 221; at the same time, the transfer transmission mechanism 51 is also used to transfer the lens product that does not pass the scanning to the throwing mechanism 53 for throwing processing. It can be understood that the pre-inspection positioning mechanism 54 and the carrier positioning mechanism 55 of the present application can, but are not limited to, respectively obtain the position and angle information of the lens product W and the lens fixture 221 through dual cameras to ensure that the lens product W can be successfully placed on the lens fixture 221.

[0087] Alternatively, if Fig.16 As shown, the transfer transmission mechanism 51 includes a transfer conveyor 511, a transfer tool 512 drivingly connected to the transfer conveyor 511, and a limiting clamp 513 disposed on the transfer tool 512. In this way, when the transfer conveyor 511 drives the transfer tool 512 to perform the lens transfer and transportation action, the limiting clamp 513 can limit the position of the lens product W to ensure the stability of the lens product W during high-speed transportation. It is understandable that the above-mentioned clamp pad 3412 can also be added to the limiting clamp 513 to prevent the lens from being damaged or contaminated when limiting the lens product W, and this application will not repeat it in detail.

[0088] It is worth noting that the lens inspection device 1 of the present application uses a visual positioning system such as a CCD system for automatic positioning guidance throughout the process of picking and placing materials, so as to improve the accuracy and efficiency of picking and placing materials. Fig.14 As shown, the lens picking and placing mechanism 341 may further include a visual positioning system 3414 for accurately positioning the lens clamp 3411 .

[0089] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
