Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical bottle sealing gasket detection, and particularly relates to a full-automatic medical bottle sealing gasket detection machine. Background Art
[0002] Currently produced medical gaskets often have quality defects that directly impact their sealing performance, especially when used to seal exported pharmaceutical bottles. These defects can directly impact the quality of the liquid medicine. Therefore, strict production requirements are imposed on these gaskets, and any defective gaskets that appear during the production process must be screened out.
[0003] Most medical gasket manufacturers on the market use manual visual selection to select defective products. This not only has high labor costs, but also makes it difficult to fully grasp the appearance, shape and size of the gaskets. Manual selection cannot completely detect small creases, small white spots, and small black spots on such gaskets, resulting in a high missed detection rate, which affects the qualified rate of medical gaskets. Enterprises are in urgent need of a fully automatic medical gasket detection machine.
[0004] There are glass turntable inspection machines for this type of gasket on the market. The defect of this type of equipment is that when inspecting the back of the gasket, the inspection effect is poor due to the glass in between. It cannot detect defects such as small white spots and small creases, and cannot meet customer inspection requirements. Utility Model Content

Furthermore, to facilitate a better understanding of this application, certain specific details are described in detail below in the detailed description of this application. Those skilled in the art will be able to fully understand this application without these details.
[0016] See also Figures 1 to 4 A fully automatic medical bottle sealing gasket detection machine includes a feeding device 1, a material sorting vibration plate 2, a first conveying device 3, a second conveying device 4, a display 5 and a main unit 6 which are arranged in sequence. The gasket 7 enters the material sorting vibration plate 2 from the feeding device 1, and the gasket 7 after being sorted by the material sorting vibration plate 2 enters the first conveying device 3 and then enters the second conveying device 4. The second conveying device 4 is provided with a suction device. The first conveying device 3 is provided with a first trigger optical fiber 308, a first workstation, a second workstation, a third workstation and a first waste air nozzle 307 in sequence along its conveying direction. The second conveying device 4 is provided with a second trigger optical fiber 406, a fourth workstation, a fifth workstation and a second waste air nozzle 405 in sequence along its conveying direction.
[0017] A parallel light source 301 and a first camera 302 are provided at the position of the first workstation, and the parallel light source 301 and the first camera 302 are respectively provided on both sides of the first conveying device 3. A first low-angle ring light source 303 and a second camera 304 are provided at the position of the second workstation, and the first low-angle ring light source 303 is provided above the first conveying device 3, and the second camera 304 is provided above the first low-angle ring light source 303. A first large ring light source 305 and a third camera 306 are provided at the position of the third workstation, a second low-angle light source 401 and a fourth camera 402 are provided at the position of the fourth workstation, and a second large ring light source 403 and a fifth camera 404 are provided at the position of the fifth workstation.
[0018] The first large ring light source 305 is arranged above the first conveying device 3, the third camera 306 is arranged above the first large ring light source 305, the second low-angle light source 401 is arranged below the second conveying device 4, the fourth camera 402 is arranged below the second low-angle light source 401, the second large ring light source 403 is arranged below the second conveying device 4, and the fifth camera 404 is arranged below the second large ring light source 403.
[0019] On the first conveyor, the gasket passes through the first trigger fiber, the first station, the second station, the third station, and the first exhaust nozzle. The first station uses a parallel light source, with a first camera positioned on the side of the gasket, primarily inspecting for flatness and dimensional defects. The second station uses a low-angle ring light source, with a second camera positioned on the front of the gasket, primarily inspecting for small white spots and creases on the gasket surface. The third station uses a large ring light source, with a third camera positioned on the front of the gasket, primarily inspecting for defects such as burrs on the gasket edge and inner hole. Gaskets passing through these three stations are photographed and sent to the host computer, where an internal algorithm determines whether they are qualified. Unqualified products are blown off by compressed air when passing through the first exhaust nozzle. Qualified products pass through the exhaust nozzle and enter the second conveyor.
[0020] A suction device is installed on the back of the belt of the second conveyor device, which sucks the front of the gasket onto the belt. The gasket follows the belt and passes through the second trigger optical fiber, the fourth station, the fifth station, and the second exhaust nozzle in turn. The light source of the fourth station is a low-angle ring light, and the camera is placed on the back of the gasket, mainly to detect small white spots and crease defects on the surface of the gasket; the light source of the fifth station is a large ring light, and the camera is placed on the front of the gasket, mainly to detect defects such as burrs on the edge of the gasket and the inner hole.
[0021] The principle of this new inspection method differs from that of traditional glass turntable inspection machines. When inspecting this type of gasket, these machines require lighting and imaging the back of the gasket through the glass, resulting in poor imaging quality. Small creases and small white spots cannot be detected, failing to meet customer requirements and product standards. The main advantage of this new inspection method is that lighting and imaging are performed directly on the object to be inspected, resulting in excellent imaging quality and complete detection of small creases and small white spots.
[0022] The test results will be shown on the display.
[0023] When the utility model is working, piles of gaskets to be inspected are poured into the material bin; the gaskets are controlled by the feeding device and enter the material sorting vibration plate, and are arranged one by one in sequence from the circular vibration sorting part, and enter the straight vibration track; the gaskets enter the first conveying device from the straight vibration track; on the first conveying device, the gaskets pass through the first sensing optical fiber, the first workstation, the second workstation, and the third workstation in sequence to complete the front and side inspections of the gaskets; the program determines that unqualified gaskets will be blown into the waste channel at the first exhaust nozzle, and qualified gaskets will enter the second conveying device after passing through the first exhaust nozzle; on the second conveying device, the gaskets pass through the second sensing optical fiber, the fourth workstation, and the fifth workstation in sequence to complete the back side inspection of the gaskets; the program determines that unqualified gaskets will be blown into the waste channel at the second exhaust nozzle, and qualified gaskets will enter the qualified product channel after passing through the exhaust nozzle; so far, all-round inspection of the gaskets is completed.
[0024] The feeding device is mainly composed of a feeding device, a silo, a straight vibration feeder, a frame, etc. Piles of gaskets are poured into the silo, and the vibrating plate is stably fed by the straight vibration feeder. In the actual process, due to the soft material of the gaskets and their strong adsorption force, the piles of gaskets are piled inside the silo and cannot fall onto the straight vibration feeder, requiring human intervention. The present invention solves this problem by adding a feeding device to the silo. A rotating cylinder is installed on the top of the feeding device, and the rotating cylinder rotates intermittently to drive the bottom feeding claw to rotate, so that the feeding claw rotates, destroying the internal force balance of the gaskets in the silo, causing the gaskets to fall quickly.
[0025] The first conveyor, driven by a motor, rotates a flat belt. A suction chamber beneath the belt uses negative pressure to ensure smooth operation. As the gaskets enter the belt, they pass through a guide mechanism that straightens the scattered gaskets that have been transported onto the belt by direct vibration, improving subsequent inspection stability.
[0026] The rear of the first conveying device is connected and fixed with a manually adjustable lifting device. By adjusting the height of the lifting device, the upper and lower height distances from the flat belt to the straight vibrating track outlet can be adjusted quickly and conveniently, thereby improving the stability of the gasket feeding and blanking. When cleaning and disassembling the belt, the lifting device can be operated to lower the belt to increase the distance from the belt to the straight vibrating track, making it easier to disassemble the belt. Otherwise, the belt will be pressed between the wheel and the track by the straight vibrating track and cannot be disassembled and cleaned normally.
[0027] On the second conveying device, when the gasket passes through the junction of the first and second conveying devices, since the first conveying device is a flat belt conveyor and the second conveying device is a perforated suction belt, the suction belt has a hole in the middle, and a suction chamber is installed on the back of the suction belt. The suction chamber is connected to the fan pipeline, and the fan generates negative pressure suction, which sucks the front of the gasket onto the suction belt, exposing the back of the gasket, so that the camera can detect defects on the back of the gasket. The suction belt drives the wheel to rotate through the operation of the motor, so that the belt runs and conveys the gasket to the right. The back plate of the second conveying device is fixed to the lifting device at the back. The lifting device is manually adjusted to adjust the belt gap between the first and second conveying devices, so that the gasket can stably transition from the flat belt to the suction belt.
