Foreign matter at the bottom of the packaging bottle must be detected by taking a photo of the bottom of the bottle.

[0003] At present, the foreign body detection device for bottle bottom is usually equipped with a transparent glass section on the conveying track, such as Figure 1 As shown, when the packaging bottle passes over the glass segment, the camera detects from the bottom of the bottle, but the glass will be scratched after long-term use, affecting the accuracy of the detection and needs to be replaced regularly; some solutions, such as our company's utility model patent CN209311355U, discloses a foreign body detection device for the bottom of a syringe bottle, which clamps the neck of the packaging bottle by a support rail so that the bottom of the packaging bottle is suspended, thereby detecting the packaging bottle on the conveyor track. This solution has a high strength requirement for the neck of the packaging bottle. For an ampoule bottle with a broken neck, after the support rail clamps the neck of the ampoule bottle, the ampoule bottle is easily broken during the process of the ampoule bottle being driven by the dial wheel to move; therefore, it is necessary to improve the existing technology to be suitable for the detection of foreign bodies at the bottom of the ampoule bottle.

[0026] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0027] Please also read Figures 2 to 5 The bottle bottom foreign matter detection device for ampoule bottles of this embodiment includes a conveying track 1 for carrying ampoule bottles 5, a bottle pushing mechanism 2 for driving the ampoule bottles 5 to move along the conveying track 1, and a detection mechanism 3 arranged below the conveying track 1 for detecting foreign matter at the bottom of the ampoule bottles 5 on the conveying track 1. The conveying track 1 includes a wide track 11 and a connecting track 12. A notch 111 is provided on the wide track 11 for the detection mechanism 3 to collect images. The connecting track 12 connects the two ends of the notch 111. The width of the connecting track 12 is smaller than the width of the wide track 11.

[0028] The bottle bottom foreign body detection device for ampoule bottles of this embodiment drives the ampoule bottle 5 to move along the wide track 11 through the bottle pushing mechanism 2. Since the width of the connecting track 12 is smaller than the width of the wide track 11, when the ampoule bottle 5 passes through the connecting track 12 on the notch 111, the detection mechanism 3 can capture an image of the bottle bottom of the ampoule bottle 5, thereby determining whether the ampoule bottle 5 is a qualified product. The device has a simple structure and does not need to be replaced regularly, which can save labor costs. It does not apply external force to the neck of the ampoule bottle 5, which can prevent the ampoule bottle from breaking, thereby ensuring that the mandatory inspection is carried out smoothly.

[0029] In this embodiment, the width of the connecting track 12 is 0.2-0.7 mm. When the width of the connecting track 12 is less than 0.2 mm, the supporting area is small and the ampoule bottle 5 is easy to shake. When the width of the connecting track 12 is greater than 0.7 mm, the shielding area is large, which affects the detection accuracy. Optionally, the width of the connecting track 12 is 0.5 mm.

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, the width of the wide track 11 is smaller than the outer diameter of the ampoule bottle 5, and the connecting track 12 is arranged along the diagonal of the notch 111; the bottle pushing mechanism 2 rotates clockwise, and the ampoule bottle 5 gradually transitions from contacting the connecting track 12 on the right side of the bottom to contacting the connecting track 12 on the left side of the bottom during the process of passing through the connecting track 12, which can prevent the connecting track 12 from always being in the middle position of the ampoule bottle 5, which may block foreign matter in the middle position of the bottom of the ampoule bottle 5. Therefore, as long as there is foreign matter at the bottom of the ampoule bottle 5, it will appear in the field of view of the detection mechanism 3 and be judged as a defective product.

[0031] In this embodiment, an illumination mechanism 4 is also included for illuminating the bottom of the ampoule bottle 5. The illumination mechanism 4 includes a first support seat 41, a light source mounting seat 42 arranged on the first support seat 41, a light source 43 arranged on the light source mounting seat 42, and a fastener 44 for connecting the first support seat 41 and the light source mounting seat 42.

[0032] In this embodiment, a circular hole is provided on the first support seat 41, and a waist-shaped hole corresponding to the circular hole is provided on the light source mounting seat 42. The fastener 44 positions the relative position of the first support seat 41 and the light source mounting seat 42 to adjust the distance between the light source 43 and the ampoule bottle 5, so that the detection mechanism 3 has good exposure when collecting the pattern, and can ensure the clarity of the pattern collected by the camera 31, thereby ensuring the accuracy of the detection. Optionally, the circular hole on the first support seat 41 is a threaded blind hole, and the fastener 44 is a screw. Optionally, the circular hole on the first support seat 41 is a through hole, and the fastener 44 is a bolt. It is understandable that the light source mounting seat 42 may also be provided with a circular hole, the first support seat 41 may be provided with a waist-shaped hole, and the fastener 44 may be a bolt.

[0033] In this embodiment, two light source mounting seats 42 are respectively arranged on both sides of the connecting track 12; for some of the medicine liquids in the ampoule bottle 5, the concentration is high and the color is dark. When one side is used for lighting, the glass attached to the bottom of the bottle may not be displayed for the medicine liquid with high concentration and dark color; by using light sources to illuminate both sides of the ampoule bottle 5 at the same time, the light can pass through the medicine liquid to display the glass attached to the bottom of the bottle, which can improve the accuracy of detection.

[0034] In this embodiment, the detection mechanism 3 includes a camera 31 disposed below the connecting track 12 and a second support base 32 for supporting the camera 31 , and has a simple structure and stable support.

[0035] In this embodiment, the second support base 32 is provided with a through hole for installing the camera 31 and a screw 33 for positioning the camera 31. Loosening the screw 33 can adjust the distance between the camera 31 and the bottom of the ampoule bottle 5. After the adjustment, tightening the screw 33 can fix the camera 31. The structure is simple and can ensure that the camera 31 is focused to collect clear patterns, thereby ensuring the accuracy of the detection.

[0036] In this embodiment, the bottle pushing mechanism 2 includes a motor 21, a dial wheel 22 driven by the motor 21, and an arc-shaped fence 23 arranged along the outer circumference of the dial wheel 22. The dial wheel 22 is provided with a groove 221 for driving the ampoule bottle 5 to move along the conveying track 1. The plurality of grooves 221 are evenly arranged along the circumference of the dial wheel 22. After the ampoule bottle 5 enters the groove 221 on the dial wheel 22, it is carried by the wide track 11. The arc-shaped fence 23 keeps the ampoule bottle 5 in the groove 221 of the dial wheel 22 at all times. The dial wheel 22 drives the ampoule bottle 5 to move. When the ampoule bottle 5 passes through the connecting track 12, the detection mechanism 3 below the connecting track 12 performs image acquisition on the bottom of the ampoule bottle 5.

[0037] In this embodiment, a protrusion 222 is formed between two adjacent grooves 221 , and a chamfer 223 is arranged on the protrusion 222 for guiding the ampoule bottle 5 into the groove 221 , so as to prevent the protrusion 222 and the arc fence 23 from crushing the ampoule bottle 5 .

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
