Considering that the defects of the traditional manual visual inspection are more and more obvious along with the increasing demand of products, the traditional manual visual inspection is not suitable for large-batch and high-precision appearance inspection of large-caliber lenses. The utility model provides a turntable detection platform and a lens detection device, which can be used for fully automatically detecting a large-caliber lens and simultaneously ensuring that the lens is kept clean and free from pollution in the detection process.
Referring specifically to fig. 1 to 16 of the drawings, according to one embodiment of the present application, there is provided a lens inspection apparatus 1, which may include a hood assembly 10 for providing a clean environment, a turntable inspection stage 20 disposed within the hood assembly 10, a loading assembly 30 for automatically loading the turntable inspection stage 20, and a unloading assembly 40 for automatically unloading the turntable inspection stage 20. In this way, the lens product W to be detected is placed into the turntable detection platform 20 through the feeding assembly 30, so that the turntable detection platform 20 automatically detects the lens product W in a clean environment, and the detected lens product W is taken out from the turntable detection platform 20 through the discharging assembly 40. It is to be understood that the lens product W referred to in the present application may be, but is not limited to being, implemented as a large caliber lens.
More specifically, as shown in fig. 3 to 8, the carousel inspection platform 20 may include a carousel rotation assembly 21, a plurality of magnetomotive carriers 22 for carrying the lens products W, a plurality of magnetomotive drive assemblies 23, and a vision inspection assembly 24. The carousel rotating assembly 21 has a circumferentially arranged loading station 2101, a detection station 2102, and a blanking station 2103. The magnetic wheel carriers 22 are circumferentially arranged on the turntable rotating assembly 21, and each magnetic wheel carrier 22 is rotatably arranged on the turntable rotating assembly 21 so as to sequentially pass through the feeding station 2101, the detecting station 2102 and the discharging station 2103 under the driving of the turntable rotating assembly 21, so that the lens product W is sequentially conveyed to the feeding station 2101, the detecting station 2102 and the discharging station 2103. The magnetic driving assemblies 23 are respectively located at the feeding station 2101, the detecting station 2102 and the discharging station 2103, and each magnetic driving assembly 23 is magnetically connected to the magnetic wheel carrier 22 at the corresponding station, so as to drive the magnetic wheel carrier 22 to rotate relative to the turntable rotating assembly 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 vision inspection assembly 24 is located at the corresponding inspection station 2102 for performing defect inspection on the lens product W carried by the magnetomotive wheel carrier 22 at the corresponding inspection station 2102.
It should be noted that dust pollution is always the biggest "enemy" produced and manufactured in the lens industry, and even if the lens product W is detected in a clean environment, the lens product W needs to be rotated to meet the requirement of a specific station on the azimuth angle of the lens in the detection process, and the existing scheme generally includes fixing a driver on a turntable and driving the driver to be connected to a carrier by a belt or gear transmission mode, and the direct contact transmission mode can generate dust particles inevitably due to friction in the transmission process, and still can cause dust pollution.
However, the turntable detection platform 20 of the present application performs non-contact driving by using a magnetic driving manner, so that the magnetic driving assembly 23 and the magnetic wheel carrier 22 are not contacted, and there is no contact friction, which greatly reduces the generation of dust particles in the transmission process, and is beneficial to improving the cleanliness of the detection device. Meanwhile, the magnetic driving assembly 23 does not need to be mounted on the turntable like a traditional mechanical driving mechanism such as belt transmission or chain transmission, and only needs to be correspondingly arranged below the turntable rotating assembly 21, so that the moment of inertia of the turntable rotating assembly 21 is greatly reduced, the requirement of the turntable rotating assembly 21 on the power of a driver is reduced, the rotation positioning precision is improved, the cost is reduced, and the realizability is improved.
Preferably, as shown in fig. 3 and 4, the number of detecting stations 2102 in the turntable rotating unit 21 may be plural, and correspondingly the number of the visual detecting units 24 is plural, and corresponds to the detecting stations 2102 one by one. In this way, the plurality of visual inspection assemblies 24 can simultaneously and concurrently inspect different appearance defect indexes of the lens product W at the corresponding inspection stations 2102, respectively, thereby greatly improving inspection efficiency. For example, the number of inspection stations 2102 may be five and the five vision inspection assemblies 24 are utilized to individually inspect the lens product W for different indices.
As shown in fig. 5 to 8, the magnetic wheel carrier 22 may include a lens jig 221 for releasably holding the lens product W, a bearing 222 rotatably connecting the lens jig 221 to the turntable rotation assembly 21, and a driven magnetic wheel 223 fixedly connected with the lens jig 221. In this way, the driven magnetic wheel 223 can drive the lens fixture 221 to rotate relative to the turntable rotation assembly 21 under the magnetic force of the magnetic force driving assembly 23, so as to change the azimuth angle of the lens product W clamped by the lens fixture 221. For example, as shown in FIG. 7, the bearing 222 referred to in the present application may be, but is not limited to being, implemented as a cross roller bearing.
Alternatively, as shown in fig. 5, the magnetic driving assembly 23 includes a driving magnetic wheel 231 matched with the driven magnetic wheel 223, a telescopic cylinder 232 drivingly connected with the driving magnetic wheel 231, and a rotating motor 233 drivingly connected with the driving magnetic wheel 231, wherein the driving magnetic wheel 231 is moved between a magnetically coupled position and a magnetically uncoupled position by being moved close to or away from the driven magnetic wheel 223 by the telescopic cylinder 232. It will be appreciated that when the driving magnetic wheel 231 is driven by the telescopic cylinder 232 to move to the magnetic coupling position near the driven magnetic wheel 223, the magnetic force generated between the driving magnetic wheel 231 and the driven magnetic wheel 223 increases to enable the driven magnetic wheel 223 to rotate along with the rotation of the driving magnetic wheel 231, and when the driving magnetic wheel 231 is driven by the telescopic cylinder 232 to move to the magnetic decoupling position far away from the driven magnetic wheel 223, the magnetic force generated between the driving magnetic wheel 231 and the driven magnetic wheel 223 is greatly reduced to enable the driven magnetic wheel 223 not to rotate along with the rotation of the driving magnetic wheel 231.
In this way, when the azimuth angle of the lens product W needs to be adjusted to meet the feeding and discharging or visual inspection requirements, the telescopic cylinder 232 drives the driving 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 driving magnetic wheel 231 to rotate to magnetically drive the driven magnetic wheel 223 to rotate relative to the turntable rotating assembly 21, so as to drive the lens fixture 221 to rotate relative to the turntable rotating assembly 21 to achieve the azimuth angle adjustment of the lens product W, when the azimuth angle adjustment is completed, the telescopic cylinder 232 drives the driving magnetic wheel 231 to move away from the driven magnetic wheel 223 to the magnetic decoupling position, and at this time, the turntable rotating assembly 21 rotates to convey the magnetic wheel carrier 22 carrying the lens product W to the next station, the driven magnetic wheel 223 will not deflect under the magnetic force of the driving magnetic wheel 231, so as to ensure that the azimuth angle of the lens product W relative to the turntable rotating assembly 21 remains unchanged, thereby facilitating the accurate positioning of the lens product W.
It should be noted that, in the whole magnetic driving process, a gap is left between the driving magnetic wheel 231 and the driven magnetic wheel 223, and no friction force exists without direct contact, so that pollution to the lens product W caused by dust generated by friction between the driving wheels can be effectively avoided.
Optionally, as shown in FIGS. 5 and 6, the magnetomotive force wheel carrier 22 further comprises a sensor tab 224, and the magnetomotive force drive assembly 23 further comprises a position sensor 234 mated with the sensor tab 224 for detecting a distance from the sensor tab 224 for precise positioning by the cooperation of the position sensor 234 with the sensor tab 224 to ensure precise movement of the active magnetomotive force wheel 231 to the magnetically coupled position or the magnetically decoupled position.
