At the same time, a tray shortage sensor 515 is provided at the lower part of the empty tray placement frame 513. The tray shortage sensor 515 is arranged near the upper position of the empty tray partition tongue 514. Generally, a photoelectric sensing device can be adopted. Under normal circumstances, when the empty tray placement frame 513 retains enough part loading trays 600, the light beam and other sensing media emitted by the tray shortage sensor 515 will be blocked by the part loading tray 600. When the empty tray placement frame 513 has insufficient part loading trays 600, the height of the tray shortage sensor 515 is not blocked by the part loading tray 600, and a warning is issued at this time that the part loading tray 600 needs to be supplemented.

The automatic screening turntable device for automobile parts according to claim 1 is characterized in that: The material picking unit (220) comprises a rotating material picking base (221), the rotating material picking base (221) is fixedly provided with a plurality of suction cup lifting mechanisms (222), and the suction cup lifting mechanisms (222) are provided with a plurality of part material picking suction cups (223).

8. A method for screening and loading automobile parts using the automatic screening turntable device for automobile parts according to claims 1 to 7, characterized in that: The steps include: S1. Parts vibration alignment step: the automobile parts to be screened are put into a vibration feeder (110), the vibration feeder (110) breaks up the agglomerated automobile parts through vibration, and then conveys them to a parts alignment plate on a flexible vibration plate (120), the parts alignment plate is provided with a limit cavity for aligning the positions of the automobile parts, and after the high-frequency disordered vibration of the flexible vibration plate (120), some automobile parts are aligned to a preset angle, and at this time, the parts alignment visual detection unit (130) provided above the parts alignment plate can identify these automobile parts, and transmit the position coordinates of some automobile parts to the material preparation line feeding device (200); S2. Parts preparation step, in step S1, after the parts alignment visual inspection unit (130) transmits the position coordinates of some automobile parts aligned to a preset angle to the material preparation line feeding device (200), the material preparation line feeding device (200) uses the manipulator (210) and the material taking unit (220) to absorb these parts at a preset angle, and then sequentially place them in the parts limiting fixture (320) on the material preparation conveyor belt (310). When the parts limiting fixture (320) loaded with automobile parts moves on the material preparation conveyor belt (310) and passes under the parts appearance visual inspection unit (330), the parts appearance visual inspection unit (330) will detect whether the automobile parts on the parts limiting fixture (320) are deformed; S3. Parts loading step: The empty tray support plate (512) supports the empty parts loading trays (600) stacked in the empty tray placement frame (513) from below. When an empty parts loading tray (600) is needed, the empty tray support plate (512) moves downward with all the parts loading trays (600) in the empty tray placement frame (513) driven by the empty tray lifting mechanism (511). During the downward movement, several empty tray spacer tongues (514) are inserted into the lower end of the second to last layer of parts loading trays (600), so that except for the bottom layer of parts loading trays (600), the remaining parts loading trays ( The parts loading tray (600) are all left in the empty tray placement frame (513), and the parts loading tray (600) on the bottom layer is finally moved to the tray transfer conveyor (560) during the descent of the empty tray support plate (512), and then the empty parts loading tray (600) is moved to the first tray lifting device (520), where the empty parts loading tray (600) is stopped by the extended tray stop rod (525), and at this time, the tray positioning support plate (522) is driven by the operating tray lifting mechanism (521) to lift the empty parts loading tray (600) from below. The tray transfer conveyor (560) is configured such that the empty parts loading tray (600) is just stuck between the plurality of tray limiting blocks (523). At this time, the loading device (400) on the tray loading line cooperates with the material taking unit (220) through the manipulator (210) to transfer the automobile parts that have passed the inspection of the parts appearance visual inspection unit (330) in step S2 from the parts limiting fixture (320) to the empty parts loading tray (600) in sequence, until the empty parts loading tray (600) is filled with automobile parts, and the tray positioning support plate (522) lowers the fully loaded parts loading tray (600) back to the tray transfer conveyor (560). 60), at this time, the tray cut-off rod (525) is lowered, and the fully loaded parts loading tray (600) is transported to the second tray lifting device (530), and then the fully loaded parts loading tray (600) is lifted in the same manner as the first tray lifting device (520), and then the tray full tray visual inspection unit (550) detects whether the fully loaded parts loading tray (600) is full of automobile parts. After the inspection is correct, the fully loaded parts loading tray (600) is transferred to the bottom of the full tray placement frame (543), and then lifted into the full tray placement frame (543) by the full tray lifting mechanism (541) to complete the final storage.
