The discharging and film laminating device 510 includes a first discharging track 511, a first film laminating mechanism 512, and a second film laminating mechanism 513. The first film laminating mechanism 512 and the second film laminating mechanism 513 are respectively located on opposite sides of the first discharging track 511. The first film laminating mechanism 512 is used to provide a first lower film to the first discharging track 511. The transfer device is used to transport the camera cover plate that has been transported by the rotary positioning table 100 and completed the appearance inspection to the first lower film on the first discharging track 511.

[0040] Through the appearance inspection assembly 400, reliable appearance defect inspection can be carried out on the camera cover plate, effectively controlling the inspection quality with high inspection accuracy. The loading and film tearing assembly 200 is provided with a film tearing mechanism 230, which can tear off the protective film of the to-be-inspected tape to ensure effective and reliable appearance inspection subsequently. Through the handling assembly 300, the camera cover plates in the to-be-inspected tape can be transported to the rotary positioning table 100 one by one. The appearance inspection assembly 400 can perform appearance inspection on the camera cover plates one by one with reliable inspection results. After the inspection is completed, the camera cover plates can be transported to the discharging and packaging assembly 500 by the second handling mechanism. The discharging and packaging assembly 500 can package the transported camera cover plates into a first product tape through the film laminating mechanism and send them out, with high automation and high inspection efficiency.

[0041] It can be understood that with reference to Figure 3As shown in the figure, there are two sets of loading and film tearing assemblies 200, that is, the camera cover appearance inspection device includes two loading tracks 210, two pulling mechanisms 220 and two film tearing mechanisms 230. The loading tracks 210 are used to transport the tapes to be inspected. A pulling mechanism 220 and a film tearing mechanism 230 are provided on both opposite sides of each loading track 210. Each pulling mechanism 220 and film tearing mechanism 230 act on the corresponding loading track 210, and can simultaneously perform loading and corresponding film tearing operations on two tapes to be inspected. During the processing, the handling assembly 300 can alternately load the camera covers on the two tapes to be inspected, which can effectively improve the loading efficiency and thus improve the inspection efficiency.

[0042] Specifically, the pulling mechanism 220 includes a first winding roller 221 and two clamping rollers 222. The two clamping rollers 222 are arranged side by side. The first winding roller 221 is located on one side of the two clamping rollers 222. The film head of the bottom film in the tape to be inspected is fixed to the first winding roller 221. The two clamping rollers 222 clamp the bottom film of the tape to be inspected, and the two clamping rollers 222 rotate to drive the bottom film forward to pull the tape to be inspected forward. The first winding roller 221 rotates to wind up the bottom film of the tape to be inspected; the film tearing mechanism 230 includes a second winding roller 231 and a pick-off knife 232. The film head of the protective film in the tape to be inspected is fixed to the second winding roller 231. The pick-off knife 232 is arranged above the loading track 210, and the pick-off knife 232 presses against the upper surface of the tape to be inspected to prevent the protective film that has not reached the designated area from being torn off the bottom film. The first winding roller 221, the clamping rollers 222 and the second winding roller 231 are all provided with corresponding drive structures.

[0043] It can be understood that referring to Figure 3 As shown in the figure, the loading and film tearing assembly 200 further includes a pre-pressing roller 240. The pre-pressing roller 240 is arranged above the inlet end of the loading track 210. The pre-pressing roller 240 is rotatably connected to the loading track 210 through a pre-pressing seat. The pick-off knife 232 is located in the middle section of the loading track 210, which can ensure that the tape to be inspected between the inlet end of the loading track 210 and the pick-off knife 232 maintains a stable state, and the camera cover between the outlet end of the loading track 210 and the pick-off knife 232 is exposed to the external environment, which can be used for the handling assembly 300 to perform handling. The film head of the bottom film of the tape to be inspected bypasses the outlet end of the loading track 210, passes through the two clamping rollers 222 and then reaches and is fixed to the first winding roller 221. The tape to be inspected advances along the loading track 210 under the pulling action of the pulling mechanism 220. When passing through the pre-pressing roller 240, the tape to be inspected is further pressed, which can ensure that the camera cover is effectively adhered to the bottom film, and avoid the protective film pulling the camera cover out when the subsequent film tearing mechanism 230 tears the film of the tape to be inspected, which can effectively improve the reliability of the film tearing action.

[0044] It can be understood that referring to Figure 4As shown, the handling assembly 300 includes two first handling driving mechanisms 310 and two first grippers 320. The two first grippers 320 are respectively connected to the two first handling driving mechanisms 310. The first handling driving mechanism 310 is used to drive the first gripper 320 to move, and the first gripper 320 is used to grip and handle the camera cover plate. Optionally, the first gripper 320 is a vacuum chuck.

The detection part and the trigger part of the anti-collision sensing mechanism 330 are respectively arranged on the two first grippers 320. The anti-collision sensing mechanism 330 is used to check the relative position between the two first grippers 320, which can effectively improve the reliability of the handling operation.

[0046] It can be understood that with reference to Figure 4 As shown, each first handling driving mechanism 310 includes a first y-axis linear module 311, a first x-axis linear module 312, and a first z-axis linear module 313.

The first y-axis linear module 311 is used to drive the first x-axis linear module 312 to move along the y-axis. The first z-axis linear module 313 is connected to the first x-axis linear module 312. The first x-axis linear module 312 is used to drive the first z-axis linear module 313 to move along the x-axis. The first gripper 320 is connected to the first z-axis linear module 313. The first z-axis linear module 313 is used to drive the first gripper 320 to move along the z-axis. The handling assembly 300 further includes an anti-collision sensing mechanism 330. The detection part and the trigger part of the anti-collision sensing mechanism 330 are respectively a groove-shaped photoelectric sensor and a trigger piece. The groove-shaped photoelectric sensor and the trigger piece are respectively connected to the driving ends of the two first y-axis linear modules 311. Once the trigger piece reaches the groove-shaped photoelectric sensor, an alarm signal can be formed to avoid damaging the equipment structure due to collision.

[0047] It can be understood that with reference to Figure 1 As shown, the transfer device includes a transfer conveyor mechanism 520, a first material-gripping mechanism 530, and a second material-gripping mechanism 540. The transfer conveyor mechanism 520 is used to convey the camera cover plate.

The second material-gripping mechanism 540 is used to handle the camera cover plate on the transfer conveyor mechanism 520 to the first film-laying position of the first blanking track 511. The transfer conveyor mechanism 520 can provide more reaction time for the subsequent handling operations to achieve further screening operations.

[0048] It can be understood that with reference to Figure 8As shown in the figure, the first material grasping mechanism 530 includes a rotary driving member 531, a positioning plate 532, a slider 533, a swing arm 534, a linkage member 535, a y-axis linear guide rail 536, a z-axis linear guide rail 537, and a third grasping member 538. The rotary driving member 531 is connected to the swing arm 534, and the rotary driving member 531 is used to drive the swing arm 534 to rotate. The positioning plate 532 is provided with an arc-shaped guiding groove 539. The slider 533 is slidably connected to the guiding groove 539. The rotation center of the swing arm 534 is located at the center of the guiding groove 539, that is, the rotation center axis of the swing arm 534 passes through the center of the guiding groove 539. One end of the swing arm 534 is rotatably connected to the slider 533 and the linkage member 535. The y-axis linear guide rail 536 is connected to the positioning plate 532.

The linkage member 535 can move along the z-axis under the guiding action of the z-axis linear guide rail 537. The third grasping member 538 is connected to the linkage member 535. The third grasping member 538 can be a vacuum chuck. During specific operation, after the third grasping member 538 grasps the camera cover plate on the rotary positioning table 100, the rotary driving member 531 drives the swing arm 534 to rotate around the center of the arc-shaped guiding groove 539. The slider 533 moves along the arc in the guiding groove 539. Under the limiting action of the y-axis linear guide rail 536 and the z-axis linear guide rail 537, the stability of the movement action of the third grasping member 538 can be ensured. The third grasping member 538 grasping the camera cover plate realizes an arc movement in the yz plane, and can form an action of pulling the camera cover plate away from the rotary positioning table 100 and an action of placing the camera cover plate into the transfer conveyor mechanism 520, which can effectively improve the reliability of the handling action, avoid damage to the camera cover plate, and the overall structure is simple and stable, with high handling efficiency. Specifically, the fixed part of the y-axis linear guide rail 536 is connected to the positioning plate 532, the fixed end of the z-axis linear guide rail 537 is connected to the movable part of the y-axis linear guide rail 536, and both the linkage member 535 and the third grasping member 538 are connected to the movable part of the z-axis linear guide rail 537. The linkage member 535 and the third grasping member 538 can realize movements with the same trajectory.

[0049] It can be understood that, with reference to Figure 7 As shown in the figure, the transfer conveyor mechanism 520 includes a conveyor belt 521, a limit driving mechanism 522, and a limiting member 523. The conveyor belt 521 is used to convey the camera cover plate. The limit driving mechanism 522 is connected to the limiting member 523. The limit driving mechanism 522 is used to drive the limiting member 523 to move perpendicular to the conveying direction of the conveyor belt 521, and the driving direction of the limit driving mechanism 522 is parallel to the conveying plane of the conveyor belt 521, which can effectively improve the controllability of the conveying trajectory of the camera cover plate on the conveyor belt 521. Optionally, the limit driving mechanism 522 is a cylinder.

[0050] Specifically, there are two limit driving mechanisms 522 and two limit members 523. Driven by the corresponding limit driving mechanisms 522, the two limit members 523 can limit the relative two side edges of the camera cover plate on the conveyor belt 521, so as to improve the reliability of the conveying action.

[0051] It can be understood that, referring to Figure 9 As shown, the second material grabbing mechanism 540 includes a second x-axis linear module 541, a second y-axis linear module 542, a second z-axis linear module 543 and a second gripping member 544.

[0052] Specifically, the second gripping member 544 includes three vacuum suction cups. By arranging multiple vacuum suction cups, multiple camera cover plates can be carried simultaneously, which can effectively improve the handling efficiency.

[0053] It can be understood that, referring to Figure 2 As shown, the rotary positioning table 100 includes a rotary driving mechanism 110, a turntable 120 and a jig 130. The turntable 120 is connected to the rotary driving mechanism 110. The jig 130 is connected to the turntable 120. The rotary driving mechanism 110 is used to drive the turntable 120 to rotate along the horizontal plane, so that the jig 130 reaches the corresponding station. The jig 130 is used to fix the camera cover plate. The rotary driving mechanism 110 is a direct drive motor, which can directly drive the turntable 120 to rotate. By rotating, the camera cover plate on the jig 130 can be driven to each corresponding station, which can effectively save space.

[0054] It can be understood that, referring to Figure 5 As shown, the appearance inspection assembly 400 includes a plurality of inspection units 410. Each inspection unit 410 is distributed above the corresponding station.

At least one inspection unit 410 is set to include an inspection camera 411 and a light source 412 with their central optical axes coaxially arranged. At least one inspection unit 410 is set to include an inspection camera 411 and a light source 412 with an acute angle formed between their central optical axes. By setting different inspection units 410, different defects of the camera cover plate can be inspected. Among them, the central optical axis of the inspection camera 411 in the inspection unit 410 can be set perpendicular to the turntable 120, or the central optical axis of the inspection camera 411 in the inspection unit 410 is set to form an acute angle with the rotation axis of the turntable 120, enabling inspections of the camera cover plate at different angles, thereby realizing inspections of different types of appearance defects and ultimately achieving a more comprehensive inspection effect on the camera cover plate. Along the movement trajectory of the rotary positioning table 100, a loading station, an inspection station, and an unloading station are successively arranged. Under the action of the turntable 120 and the rotation drive mechanism 110, the jig 130 can reach each station.
