[0036] Working principle of the present invention: During the use of the present invention, the operator can first place the prepared material in the first material bin 31. The prepared material is formed by stacking a plurality of mobile phone films and a plurality of spacer papers in sequence. When loading, the prepared material linear module 34 drives the prepared material plate 35, the first material bin 31 on the prepared material plate 35, and the prepared material in the first material bin 31 to be transferred to the top of the lifting device. Then, the prepared material is detected by the coordinated cooperation of the prepared material detection camera 62 and each prepared material detection light source 63 on the prepared material detection device 6 to avoid the occurrence of wrong cross-taking between the mobile phone film and the spacer paper. If the spacer paper is on the top, the spacer paper is taken away to any second material bin 32 by the first transfer device 4. If the mobile phone film is on the top, the mobile phone film is transferred by the second transfer device 7. When the top layer is the separator paper, the first linear module 41 drives the first transfer plate 42 and the second linear module 43 and the second transfer plate 44 on the first transfer plate 42 to be transferred to the top of the separator paper, and the first suction cup 46 transfers the separator paper through the drive of the second linear module 43, and transfers it to any second silo 32, and after the separator paper in the first silo 31 is transferred away, the lifting plate 53 at the bottom of the connecting frame 36 lifts the prepared material through the drive of the lifting linear module 52, and after the separator paper is removed, the adjacent mobile phone film in the lower layer can be lifted to the top layer, and after the mobile phone film is removed, the adjacent separator paper in the lower layer can be lifted to the top layer, and the first suction cup 46 is set as a non-contact Bernoulli suction cup, which can effectively place the separator paper and the mobile phone film to be taken away at the same time, thereby ensuring orderly feeding; After the spacer paper is taken away, the mechanical arm 72 on the second transfer device 7 drives the first rotary motor 73, the mold removal bracket 74 on the first rotary motor 73 and the second suction cup 75 to be transferred to the top of the first silo 31, and the positions of the second suction cups 75 are adjusted by driving the mechanical arm 72 and the first rotary motor 73 to drive the mold removal bracket 74, so that the second suction cups 75 can face the mobile phone film. Similarly, the second suction cups 75 are also set as Bernoulli suction cups to prevent the mobile phone film and the spacer paper from being taken out at the same time. The mobile phone film is transferred to the receiving device 8 under the drive of the mechanical arm 72 and the adsorption of the second suction cups 75; Each receiving device 8 receives the mobile phone film on the second transfer device 7, and each receiving platform 85 is set to a ceramic vacuum adsorption platform. On the one hand, it can ensure the stability of each mobile phone film placed on the receiving platform 85, and on the other hand, it can reduce the friction between the mobile phone film and the receiving platform 85 to avoid secondary scratches. It is also convenient for the later positioning and adjustment of the mobile phone film. After the mobile phone film is placed on the receiving platform 85, the second rotating motor 82 drives the rotating platform 83 to rotate 180 degrees. At this time, the mobile phone film on the receiving platform 85 is transferred to the bottom of the positioning detection component 88. The positioning detection camera 882 on the positioning detection rod 881 shoots and detects the CAM hole of the mobile phone film on the receiving platform 85 through the coordinated cooperation with the positioning annular light source 883. At the same time, the receiving platform 85 on the other side of the rotating platform 83 can take away the mobile phone film that has been detected completely through the second transfer component, and place a new mobile phone film to be detected. When testing, first, the first auxiliary cylinder 892 on the auxiliary bracket 891 drives the pressing block 856 to press one side of the mobile phone film against the first pressing strip 851, and then the second auxiliary cylinder 894 on the side plate 893 drives the pressing rod 857 to press the other side of the mobile phone film against the second pressing strip 852, so as to adjust the positioning of the mobile phone film. After the adjustment is completed, the first auxiliary cylinder 892 leaves the pressing block 856, and the second auxiliary cylinder 894 and the pressing rod 857 are separated from the material receiving platform 85, so as to avoid the interference between the pressing rod 857 and the pressing block 856 and the placement platform when the rotating platform 83 rotates. The positioning detection camera 882 and the positioning ring light source 883 shoot and detect the CAM hole on the mobile phone film. When the position of the CAM hole is detected to be deviated, it can be fine-tuned through the adjustment component 87 at the bottom of the material receiving bottom plate 86. During the fine-tuning process, each material receiving platform 85 is adjusted by the first driving motor 871 to the first The driving of the first connecting block 872, the cooperation of the first slider 8721 and the first slide rail 831, and the cooperation of the fourth slider 8761 and the fourth slide rail 8752 are used to adjust the position along the extension direction of the rotating platform 83, and the driving of the third connecting block 875 by the second driving motor 874, the cooperation of the second slider 8731 and the second slide rail 8722, and the cooperation of the third slider 8751 and the third slide rail 832 are used to fine-tune the position along the direction perpendicular to the extension of the rotating platform 83. By setting the sliding of the first connecting block 872, the second connecting block 873, the third connecting block 875 and the fourth connecting block 876, on the one hand, the smooth adjustment of the docking material platform 85 can be ensured, and on the other hand, the docking material platform 85 can be fine-tuned in all directions, and the jamming during the fine-tuning process can be avoided, thereby ensuring the accuracy of the positioning of the CAM hole on the docking material platform 85, and at the same time, the surface of the mobile phone film can be scratched. After the positioning and calibration of the mobile phone film and the CAM hole on the docking material platform 85 is completed, the operator can first hold the rotating handle 944 to rotate the rotating shaft 942, and the rotating shaft 942 drives the driving gear 943 in the inner cavity 941 to start rotating, and the driving gear 943 adjusts the height of the OCT camera 96 ​​through the transmission cooperation with the rack 931, and the cooperation between the lifting slider 94 and the lifting slide groove 93. At the same time, when the operator needs to adjust the shooting angle of the OCT camera 96, the operator can drive the screw rod 993 to rotate, and the push block 997 presses one side of the adjustment rod 981 through the cooperation of the screw rod 993 and the threaded through hole 996 and drives the OCT camera 96 ​​to adjust the angle, and the limit pressure rod 994 resets and presses the other side of the adjustment rod 981 through the continuous force of the reset spring 999, thereby realizing accurate and efficient adjustment of the OCT camera 96; After the OCT camera 96 ​​is adjusted completely, the second rotating motor 82 drives the rotating platform 83 to continue rotating 180 degrees. During this rotation, when the mobile phone film on the receiving platform 85 passes under the OCT camera 96, the OCT camera 96 ​​quickly and accurately detects the deep scratches in the mobile phone film. On the one hand, the problem of low quality and low efficiency caused by manual detection in the prior art can be effectively solved through the automated loading, positioning and detection method. On the other hand, the CAM holes on the mobile phone film can be accurately and efficiently detected in batches through the automated method. After the rotating platform 83 rotates to 180 degrees and the inspection is complete, the second suction cup 75 grabs the mobile phone film through the driving of the first rotating motor 73 by the mechanical arm 72 and the driving of the mold taking bracket 74 by the first rotating motor 73, and grabs the mobile phone film that fails the inspection and puts it into the second material bin 32 with spacer paper, and puts the mobile phone film that passes the inspection into the second material bin 32 without spacer paper, thereby realizing the screening of the mobile phone film. After the mobile phone film is completely sorted, the second suction cup 75 moves to the first material bin 31 again to grab the mobile phone film, so as to reciprocate the loading, transfer, positioning, correction, inspection, screening and unloading of the mobile phone film, and effectively realizes the accurate and efficient detection of CAM holes on the mobile phone film in an automated manner, with a clever structure, convenient and practical.
