Technical Field

[0001] This utility model relates to the technical field of lamp inspection and screening devices, and in particular to a multi-stage lamp inspection and screening device for butyl rubber stoppers. Background Technology

[0002] During the production and transportation of pharmaceutical butyl rubber stoppers, some products may have defects such as insufficient rubber, cracks, rubber debris, bubbles, sulfur marks, dirt, and dimensional over-limit issues. According to the customer's quality requirements and the company's quality standards, it is necessary to strictly control defective products to ensure product quality.

[0003] Existing automatic light inspection machines only distinguish between qualified and unqualified products. All products that fail the first light inspection are discharged from a rejection end, resulting in a high proportion of defects of various sizes in the products that fail the first light inspection. In particular, some neckless rubber plugs are prone to jamming during the second or even third light inspection, causing the equipment to alarm frequently and with a high risk of missed inspection, which affects product quality. Repeated inspection is time-consuming and labor-intensive, which affects the inspection efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that only distinguishing between qualified and unqualified products makes it difficult and inefficient to distinguish between defective and repairable products in subsequent inspections.

An arc-shaped screening channel with its end connected to the feeding channel is set inside the screening tray. A waste rejection tube, a non-conforming product rejection tube, a size defect rejection tube, a qualified product discharge tube one, and a qualified product discharge tube two are connected in parallel on the screening channel. A pneumatic pusher is set inside the screening channel, and the pneumatic pusher is set in a one-to-one correspondence with the waste rejection tube, the non-conforming product rejection tube, the size defect rejection tube, the qualified product discharge tube one, and the qualified product discharge tube two.

[0006] Preferably, a bottom camera is arranged vertically upward at the bottom of the exposure disk, a top camera is arranged vertically downward at the top of the exposure disk, and a side camera is fixed horizontally at the bottom of the exposure disk. The side cameras are distributed at equal angles around the axis of the exposure disk, and there are no fewer than three side cameras.

[0007] Preferably, a light shield is fixedly connected to the top of the exposure disk by a vertical rod, the top camera is located inside the light shield, a fixing frame is fixedly connected to the side wall of the light shield, and the bottom camera is connected to the fixing frame.

[0008] Preferably, a trigger sensor is arranged upstream of each of the waste rejection pipe, the non-conforming product rejection pipe, the dimensional defect rejection pipe, the qualified product discharge pipe one, and the qualified product discharge pipe two, and the detection end of the trigger sensor is located directly above the screening channel.

[0009] Preferably, each of the waste rejection pipe, non-conforming product rejection pipe, dimensional defect rejection pipe, qualified product discharge pipe one and qualified product discharge pipe two is hinged to a baffle on the connection channel with the screening channel, and a torsion spring is connected to the rotating shaft of the baffle. The pneumatic push rod is positioned directly opposite the baffle.

[0010] This invention provides a multi-stage light inspection and screening device for butyl rubber stoppers. Exposure lamps are arranged on the feeding channel of the glass preparation process, and bottom, side, and top cameras are arranged on the exposure lamps to take pictures of the rubber stoppers. After the quality of the rubber stoppers is identified, the rubber stoppers are pushed into the screening channel.

[0015] like Figure 1 and Figure 2As shown, this utility model proposes a multi-stage light inspection and screening device for butyl rubber stoppers, including a feeding tray 1 and a screening tray 4 connected by a feeding channel 2. The feeding channel 2 is arranged tangentially to the feeding tray 1 and the screening tray 4. The entire feeding channel 2 and the top of the screening tray 4 are transparent structures. An exposure tray 3 is arranged on the feeding channel 2, and a camera is mounted on the exposure tray 3. An arc-shaped screening channel 5 is set inside the screening tray 4, with its end connected to the feeding channel 2. The screening channel 5 is connected in parallel with a waste rejection tube 7, a non-conforming product rejection tube 8, a size defect rejection tube 9, a qualified product discharge tube 10, and a qualified product discharge tube 2 11. A pneumatic pusher 12 is set inside the screening channel 5, and the pneumatic pusher 12 is set in a one-to-one correspondence with the waste rejection tube 7, the non-conforming product rejection tube 8, the size defect rejection tube 9, the qualified product discharge tube 10, and the qualified product discharge tube 2 11.

[0016] An exposure plate 3 is arranged on the feeding channel, and a bottom camera 13, a side camera 14, and a top camera 16 are arranged on the exposure plate 3, for a total of six cameras to take pictures of the rubber plug. For the obtained images, the position of the rubber plug is first determined by a positioning operator, and each detection area is automatically generated. Different detection operators are set under each detection area. Generally, defects in different parts are either dark or light. By comparing the gray value difference between the defect and the adjacent defects, the defect is identified. Based on the area size of the identified defect, a preset is set, and the system automatically classifies and rejects severe defects and general defects.

[0017] The rubber stoppers are conveyed to the feeding tray 1 by a vibrating feeding device. The feeding tray 1 then conveys the material to the feeding channel 2. The feeding channel 2 is made of glass or acrylic and has high transparency. As the rubber stoppers move along the feeding channel 2, the exposure lamp flashes and the camera takes pictures of the rubber stoppers. After taking pictures and comparing the results, the rubber stoppers are conveyed into the screening channel 5 and, according to their classification, are pushed into the waste rejection tube 7, the non-conforming product rejection tube 8, the size defect rejection tube 9, the qualified product discharge tube 10 or the qualified product discharge tube 2 11 by a pneumatic pusher 12. The qualified product discharge tube 10 or the qualified product discharge tube 2 11 diverts the qualified products.

[0018] like Figure 1 and Figure 2 As shown. A bottom-facing camera 13 is vertically arranged upwards at the bottom of the exposure disk 3, a top-facing camera 16 is vertically arranged downwards at the top of the exposure disk 3, and side cameras 14 are horizontally fixed at the bottom of the exposure disk 3. The side cameras 14 are distributed at equal angles around the axis of the exposure disk 3, and there are at least three side cameras 14. The top surface of the rubber stopper is photographed through the top-facing camera 16, the bottom surface of the rubber stopper is photographed through the bottom-facing camera 13, and the entire side surface of the rubber stopper is photographed through the four side cameras 14, thus obtaining the overall surface condition of the rubber stopper.

[0019] like Figure 2 As shown. A light shield 15 is fixedly connected to the top of the exposure disk 3 via a vertical rod. The top camera 16 is located inside the light shield 15. A fixing bracket 17 is fixedly connected to the side wall of the light shield 15, and the bottom camera 13 is connected to the fixing bracket 17. The light shield 15 covers the top of the exposure disk 3, reducing the interference of external light on the rubber stopper inside the exposure disk 3 for taking pictures, and improving the quality of the pictures.

[0020] like Figure 1 As shown, each of the following is equipped with a trigger sensor 6 upstream of the waste rejection tube 7, the defective product rejection tube 8, the dimensional defect rejection tube 9, the qualified product discharge tube 10, and the qualified product discharge tube 2 11: the detection end of the trigger sensor 6 is located directly above the screening channel 5. The trigger sensor 6 counts the passing rubber plugs, and the order of the photographs facilitates the subsequent pneumatic push rod 12 to discharge the rubber plugs accordingly.

[0021] As a preferred embodiment of this utility model, each of the waste rejection pipe 7, defective product rejection pipe 8, dimensional defect rejection pipe 9, qualified product discharge pipe one 10, and qualified product discharge pipe two 11 is hinged to a baffle on its connection to the screening channel 5. A torsion spring is connected to the rotating shaft of the baffle, and the pneumatic push rod 12 is positioned directly opposite the baffle. The baffle prevents the rubber plug from accidentally entering other channels during its movement within the screening channel 5, ensuring accurate discharge of the rubber plug in the absence of the pneumatic push rod 12 to push it.
