AI Technical Summary
The existing feeding mechanism is a single-station design, which results in low equipment utilization. When it needs to feed multiple testing machines, the system complexity increases and only one testing machine is working, resulting in low efficiency.
A dual-station feeding mechanism for screening injection molded parts was designed. It adopts a spiral feeding mechanism, which realizes continuous lifting and conveying of injection molded parts through a rotating cylinder and spiral guide vanes, and provides independent feeding channels for two testing machines. The rotating cylinder is driven by a motor to ensure that the two testing machines operate at full load at the same time.
This enabled two inspection machines to operate at full capacity simultaneously, improving the efficiency of appearance inspection of injection molded parts and ensuring that each injection molded part is inspected in the same manner, thus enhancing the comprehensiveness and efficiency of the inspection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding mechanisms, and in particular to a dual-station feeding mechanism for screening injection molded parts. Background Technology
[0002] With the continuous improvement of the level of automation in the manufacturing industry and the increasingly stringent requirements for product quality control, the full appearance screening machine for injection molded parts has become a standard configuration on modern production lines. This type of equipment uses machine vision and precision sensing technology to perform high-speed and accurate automated detection and sorting of surface defects such as scratches, burrs, black spots, shrinkage, and discoloration on each injection molded part.
[0003] Currently, most mainstream feeding mechanisms are single-station designs, meaning that one set of equipment can only supply material to one testing station. When it is necessary to supply material to two or more testing machines, two inefficient solutions are usually adopted: one is to use complex material distribution or switching devices to alternately distribute a single material flow to different testing machines. This not only increases the complexity and failure rate of the system, but also results in only one testing machine working at any given time, while other equipment is idle and waiting, resulting in extremely low equipment utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-station feeding mechanism for screening injection molded parts, comprising: Feeding connection frame; A spiral feeding mechanism is provided on the upper surface of a feeding connection frame. The spiral feeding mechanism includes a first rotating cylinder, a second rotating cylinder, an injection molded part guide plate, a spiral guide vane, a receiving frame, a conveying frame, a discharge port, and a fixed base.

[0007] Preferably, the inner wall surfaces of the first rotating cylinder and the second rotating cylinder are fixedly connected with helical guide vanes. The lower ends of the two helical guide vanes are respectively located at the bottom of the corresponding first rotating cylinder and the second rotating cylinder, and the upper ends of the two helical guide vanes are respectively located on one side of the discharge port on the outer side of the upper end of the corresponding first rotating cylinder and the second rotating cylinder.
[0008] Preferably, each of the rotating cylinder one and rotating cylinder two is equipped with a motor at the connection point with the corresponding fixed base, and the output ends of the two motors are respectively connected to rotating cylinder one and rotating cylinder two for transmission.
[0009] Preferably, a partition plate is fixedly connected to the middle of the upper surface of the feeding connection frame, and a rotating cylinder one and a rotating cylinder two are respectively provided on both sides of the partition plate.

[0015] Beneficial effects This invention provides a dual-station feeding mechanism for screening injection molded parts. Compared with the prior art, it has the following advantages: 1. In this utility model, through the spiral conveying mechanism, the injection molded parts, after being processed by an injection molding machine or vibratory feeder, are fed into the interior of rotating cylinder one and rotating cylinder two respectively through two injection molded part guide tubes. Then, rotating cylinder one and rotating cylinder two are driven to rotate by two motors. At this time, the spiral guide vanes fixed on the inner wall of rotating cylinder one and rotating cylinder two rotate accordingly. The injection molded parts are smoothly and continuously spirally lifted and conveyed upward along the inner wall of rotating cylinder one and rotating cylinder two. When the injection molded parts are lifted to the top of rotating cylinder one and rotating cylinder two, they slide out from the discharge port. The material coming out of rotating cylinder one directly enters the surface of the rotating drive disk of the first inspection frame, and the material coming out of rotating cylinder two directly enters the surface of the rotating drive disk of the second inspection frame. This provides independent feeding channels for the two appearance inspection machines, so that the two inspection machines can reach full load operation at the same time, thereby improving the appearance inspection efficiency of injection molded parts. 2. In this utility model, through the set receiving rack and conveyor rack, when the injection molded part is lifted to the top of the rotating cylinder, it will slide out from the preset discharge port and be finally conveyed to the upper surface of the rotating drive disk inside the appearance screening machine frame via the receiving rack and conveyor rack below. In this way, each injection molded part can be placed on the upper surface of the rotating drive disk in almost the same position and posture, so that multiple vision inspection machines arranged around it can perform all-round appearance defect detection.

Both fixed bases 408 are fixedly connected to the feeding connecting frame 1. Injection molded part guide plates 403 are fixedly connected to the outer sides of the upper ends of the first rotating cylinder 401 and the second rotating cylinder 402. The two injection molded part guide plates 403 are symmetrical and arranged in opposite directions. The inner surfaces of the first rotating cylinder 401 and the second rotating cylinder 402... Spiral guide vanes 404 are fixedly connected to the wall surface. The lower ends of the two spiral guide vanes 404 are respectively set at the bottom ends of the corresponding rotating cylinder 1 401 and rotating cylinder 2 402. The upper ends of the two spiral guide vanes 404 are respectively set on one side of the discharge port 407 on the outer side of the upper end of the corresponding rotating cylinder 1 401 and rotating cylinder 2 402. Motors are set at the connection between rotating cylinder 1 401, rotating cylinder 2 402 and the corresponding fixed base 408. The output ends of the two motors are respectively connected to rotating cylinder 1 401 and rotating cylinder 2 402 for transmission. A partition plate 2 is fixedly connected to the middle of the upper surface of the feeding connection frame 1.

[0020] During operation, the injection molded parts, after being processed by an injection molding machine or vibratory feeder, are fed into the interiors of rotating cylinder 1 (401) and rotating cylinder 2 (402) respectively through two injection molded part guide tubes (3). Then, rotating cylinder 1 (401) and rotating cylinder 2 (402) are driven to rotate by two motors. At this time, the spiral guide vanes (404) fixed on the inner walls of rotating cylinder 1 (401) and rotating cylinder 2 (402) rotate accordingly. The injection molded parts are smoothly and continuously spirally lifted and conveyed upward along the inner walls of rotating cylinder 1 (401) and rotating cylinder 2 (402).

In this way, each injection molded part can be placed on the upper surface of the rotating drive disk 6 in almost the same position and posture, so that the multiple vision inspection machines 7 arranged around it can perform all-round appearance defect detection.
