Description

[0002] The lens protection substrate is a plastic sheet installed on the outermost layer of the camera lens. It is mainly used to protect the lens from scratches, dust and other external factors. It is usually made of wear-resistant and scratch-resistant materials, which can effectively extend the service life of the lens.

[0003] After the production of the lens protection substrate is completed, its surface flatness needs to be tested to ensure the production quality of the lens protection substrate and prevent unqualified products from entering the market. The Chinese patent with the publication number CN221685435U in the patent library discloses a lens protection substrate flatness detection device, which can detect both sides of the lens protection substrate through the cooperation of a laser detector, a telescopic mechanism, an adjustment mechanism and a flipping mechanism, and can meet the requirements for lens protection substrate flatness detection to a certain extent. However, when using this detection device, staff are required to manually place and take lenses, and the degree of automation is low. If the lenses are not placed properly, there will be large errors. It is not suitable for mass detection of lenses. At the same time, since the lenses are thin and easily fit on the placement table, there is also a problem of difficulty in taking them, which can easily reduce the detection efficiency of the lenses. ‌

[0055] The first connecting sleeve 2031 is fixedly connected with a first push rod 2033. When the insertion tube 402 is inserted into the insertion slot 203, the first push rod 2033 will squeeze the limit plate 4017 and move the limit plate 4017.

[0060] In addition, the free end of the second motor 306 passes through the fixing frame 305 and is connected to a rotating plate 307 . The rotating plate 307 is used to install a pair of guide rails 308 .

[0061] Specifically, a pair of guide rails 308 are symmetrically connected to the rotating plate 307.

When the controller 320 is running, the controller 320 charges the coil 319, and the iron core 318 can generate magnetic force under the action of the charged coil 319. The magnetic force can be used to firmly insert the metal connecting tube 317 into the second airway 4012, thereby ensuring the firmness of the connection between the metal connecting tube 317 and the connector 401.

[0095] S7. When the inspection of one side of the lens is completed and it needs to be turned over, first rotate the upper connector 401 to the top of the lens, then control the lower first telescopic member 314 to extend, so that the lower metal connecting pipe 317 is reinserted into the second air channel 4012. Stop the first vacuum pump 204, operate the second vacuum pump 321, and open the lower control valve, so that the lower connector 401 will absorb the lens. Control the pair of third motors 309 to operate, so that the pair of connectors 401 are close to each other, that is, Fig.14 The state shown in the figure is that until both connectors 401 are in contact with the lens, the lower control valve is closed and the upper control valve is opened, the lens will be separated from the lower connector 401 and adsorbed by the upper connector 401.

[0096] S8, control the second motor 306 to operate, and the second motor 306 drives the pair of connectors 401 to rotate 180° through the rotating plate 307. Control the connector 401 with the lens adsorbed to move down and install it on the placement table 201. Stop the second vacuum pump 321, and operate the first vacuum pump 204 again, so that the lens is adsorbed and fixed on the upper side of the placement table 201. Then, rotate the connector 401 without the lens adsorbed to Figure 1 In the state shown, the laser detector 501 can perform a flatness detection on the other side of the lens.

[0097] S9. If the lens flatness test fails, the second telescopic member 4041 is extended, and the marking pen 4043 can leave a mark on the lens surface.

[0098] S10, when the lens detection is completed, repeat step S7, then control the first motor 302 to rotate, so that the connecting head 401 with the lens adsorbed rotates to the upper side of the conveyor belt 1, and then control the lens to descend, stop the second vacuum pump 321, so that the lens is placed back on the conveyor belt 1 for transportation.
