[0037] During the operation of this automatic inspection system for foreign matter in plastic ampoules, the conveying device is first controlled to hold and transport the plastic ampoules 9; the inspection device is then controlled to inspect the plastic ampoules 9 for defects; and finally, the rejection device is controlled to reject unqualified products from the plastic ampoules 9. In summary, this automatic inspection system for foreign matter in plastic ampoules performs image acquisition during linear transport, achieving comprehensive inspection of the plastic ampoules 9. The number of plastic ampoules 9 that can be inspected is unlimited, thereby improving inspection efficiency.

[0038] It should be noted that the core improvement of the present invention lies in the detection method during the above-mentioned linear conveying process. In addition, the conveying device can only use a conveyor belt to achieve conveying and holding, or combine conveying with a conveyor belt and holding with a clamp, which should also fall within the scope of the description of this embodiment; the detection device can use image detection technology, first taking pictures, then processing the image information, and finally comparing to obtain the results, or other detection technologies can be used, which should also fall within the scope of the description of this embodiment; the rejection device can use a cylinder to directly drive the force, or a connecting rod mechanism can be used to apply force outward after being driven, which should also fall within the scope of the description of this embodiment; the control device can use a controller, such as a PLC, a computer, etc., which should also fall within the scope of the description of this embodiment.

[0039] In a specific embodiment, the conveying device includes a bottle-gripping conveyor belt 2 , which has a pair of belt bodies for holding and conveying plastic ampoule bottles 9 .

[0040] In this embodiment, the conveying device adopts a bottle clamping conveyor belt 2 to achieve the holding and conveying of the plastic ampoule bottle 9; during its operation, the plastic ampoule bottle 9 moves to the center of the bottle clamping conveyor belt 2, and under the action of the bottle clamping conveyor belt 2, it is simultaneously held and fixed and continues to be conveyed forward.

[0041] More specifically, the bottle clamping conveyor belt 2 includes a top conveyor belt 203 and a bottom conveyor belt 205 which are extended in the same direction in the conveying direction and staggered in the height direction. The top conveyor belt 203 is used to support the upper part of the plastic ampoule bottle 9, and the bottom conveyor belt 205 is used to support the lower part of the plastic ampoule bottle 9.

[0042] In this embodiment, the bottle clamping conveyor belt 2 is arranged in the middle of the frame 1, and the bottle clamping conveyor belt 2 includes a conveying drive motor 201, a bottle clamping conveyor belt driving wheel 202, a top conveyor belt 203, a conversion pulley 204, a bottom conveyor belt 205 and a driven pulley 206. The conveying drive motor 201 is arranged at the end of the bottle clamping conveyor belt 2, the bottle clamping conveyor belt driving wheel 202 is installed at the end of the conveying drive motor 201, the conversion pulley 204 is arranged in the middle of the bottle clamping conveyor belt 2, the top conveyor belt 203 is arranged between the bottle clamping conveyor belt driving wheel 202 and the conversion pulley 204, the driven pulley 206 is arranged at the front end of the bottle clamping conveyor belt 2, and the bottom conveyor belt 205 is arranged between the driven pulley 206 and the conversion pulley 204. The top conveyor belt 203 is located at the top, and the bottom conveyor belt 205 is located at the bottom.

[0043] During the linear conveying of the plastic ampoules 9, the bottle-clamping conveyor belt 2 always conveys the plastic ampoules 9 in a forward direction. However, the bottle-clamping conveyor belt 2 supports the plastic ampoules 9 in two different ways: one is supported by the top conveyor belt 203, and the other is supported by the bottom conveyor belt 205. Based on this, when the plastic ampoules 9 are supported by the top, the bottom is exposed, making it easier to capture images during inspection, thereby achieving automatic inspection of appearance and foreign matter. When the plastic ampoules 9 are supported by the bottom, the top is exposed, making it easier to capture images during inspection, thereby achieving automatic inspection of appearance and foreign matter.

[0044] Exemplarily, the bottom conveyor belt 205 is disposed at the starting end of the conveying device, and the top conveyor belt 203 is disposed at the ending end of the conveying device.

[0045] In this embodiment, the bottom conveyor belt 205 is located before the top conveyor belt 203. During the linear conveying process of the plastic ampoule 9, the plastic ampoule 9 first enters the bottom conveyor belt 205. At this time, the plastic ampoule 9 is in a state of lower support and upright placement. As it moves forward, it is convenient to inspect any position in the middle and upper part. Subsequently, the plastic ampoule 9 leaves the bottom conveyor belt 205 and enters the top conveyor belt 203. At this time, the plastic ampoule 9 is in a state of upper support and upright hanging. As it moves forward, it is convenient to inspect any position in the middle and lower part.

[0046] In a specific embodiment, the detection device includes a plurality of smart cameras arranged along the conveying direction, and different smart cameras are used to detect the plastic ampoule bottles 9 at different orientations.

[0047] In this embodiment, the detection device uses image detection to detect the appearance of the plastic ampoule bottle 9; the number of smart cameras is not limited and is adjusted according to the points to be detected.

[0048] Exemplarily, the smart cameras include a first smart camera 101 , a second smart camera 102 , and a third smart camera 103 disposed adjacent to the bottom conveyor belt 205 , and a fourth smart camera 104 , a fifth smart camera 105 , and a sixth smart camera 106 disposed adjacent to the top conveyor belt 203 .

[0049] In this embodiment, a first smart camera 101, a second smart camera 102, a third smart camera 103, a fourth smart camera 104, a fifth smart camera 105, and a sixth smart camera 106 are arranged sequentially along the conveying direction. The first smart camera 101 is used to detect the liquid level of the plastic ampoule 9, the second smart camera 102 is used to detect the upper right side of the plastic ampoule 9, the third smart camera 103 is used to detect the upper left side of the plastic ampoule 9, the fourth smart camera 104 is used to detect the lower left side of the plastic ampoule 9, the fifth smart camera 105 is used to detect the lower right side of the plastic ampoule 9, and the sixth smart camera 106 is used to detect the bottom of the plastic ampoule 9.

[0050] It should be noted that the plastic ampoule 9 is sterilized after blowing, filling, and cutting. After a series of production processes, the plastic ampoule 9 needs to be inspected for appearance and foreign matter to prevent drugs with quality problems from entering the market. The automatic detection system for foreign matter in plastic ampoules uses an intelligent camera to capture images of the plastic ampoule 9 during transportation. Through the recognition and judgment unit in the control device or the image recognition system connected to the detection device, its focus is to identify surface damage, scratches, foreign matter, liquid level, etc. of the product through image recognition technology, and then make a quality judgment on the product to determine whether the plastic ampoule 9 has defects. The defective products are rejected by the rejection device, realizing automatic detection of the plastic ampoule 9.

[0051] In addition, the automatic detection system for foreign matter on the appearance of plastic ampoules also adopts an upper and lower segmented supporting conveying method to transport the plastic ampoule bottle 9. Through double-sided and dual-area image acquisition, it realizes comprehensive detection of the plastic ampoule bottle 9, and performs image acquisition during the linear conveying process, with high production efficiency.

[0052] In addition, the conveying device further includes a bottle inlet chain plate line 3 and a bottle outlet chain plate line 4. The bottle inlet chain plate line 3 is arranged at the starting end of the conveying device, and the bottle outlet chain plate line 4 is arranged at the ending end of the conveying device.

[0053] In this embodiment, the bottle inlet chain plate line 3 and the bottle outlet chain plate line 4 respectively serve to feed and discharge plastic ampoules 9 to and from the bottle clamping conveyor belt 2. The center lines of the bottle inlet chain plate line 3 and the bottle outlet chain plate line 4 coincide with the center line of the bottle clamping conveyor belt 2. The plastic ampoules 9 are placed on the bottle inlet chain plate line 3 along this center line, thereby being fed into the bottle clamping conveyor belt 2 along this center line and discharged by the bottle outlet chain plate line 4 along this center line.

[0054] In addition, the conveying device further comprises an adjusting component 5 , which is used to adjust the center distance of the bottle clamping conveyor belt 2 .

[0055] In this embodiment, the adjustment component 5 is provided on one side of the bottle clamping conveyor belt 2 , and the center distance of the bottle clamping conveyor belt 2 can be adjusted by rotating the hand wheel of the adjustment component 5 .

[0056] In a specific embodiment, the rejecting device includes a rejecting cylinder 8 , which is arranged on one side of the bottle discharge chain line 4 .

[0057] In this embodiment, the rejecting device is driven by a cylinder to reject unqualified plastic ampoules 9 .

[0058] In addition, a material receiving box 6 and a chute 7 connecting the material receiving box 6 and the bottle discharging chain plate line 4 are provided on the other side of the bottle discharging chain plate line 4.

[0059] In this embodiment, the bottle inlet chain line 3 is arranged on one side of the frame 1, the bottle outlet chain line 4 is arranged on the other side of the frame 1, the material receiving box 6 is arranged at the lower part of one side of the bottle outlet chain line 4, for holding the rejected products, the chute 7 is arranged between the rejection port of the bottle outlet chain line 4 and the material receiving box 6, and the rejection cylinder 8 is arranged on the other side of the bottle outlet chain line 4.

[0060] In a specific work process:

[0061] The plastic ampoule 9 is conveyed by the bottle feeding chain plate line 3 into the bottom conveyor belt 205 of the bottle clamping conveyor belt 2. The bottom conveyor belt 205 supports the plastic ampoule 9 and conveys it forward. During the conveying process, the plastic ampoule 9 reaches the imaging area of ​​the first smart camera 101. The first smart camera 101 captures an image of the upper area of ​​the plastic ampoule 9. The image recognition system determines whether the liquid level of the plastic ampoule 9 is within an acceptable range.

[0062] As the plastic ampoule 9 continues to be transported forward, it enters the imaging area of ​​the second smart camera 102. The second smart camera 102 captures an image of the upper right side of the plastic ampoule 9. The image recognition system determines whether the scratches, foreign matter, or damaged bottle defects in the upper right side of the plastic ampoule 9 are within an acceptable range.

[0063] As the plastic ampoule 9 continues to be transported forward, it enters the imaging area of ​​the third smart camera 103. The third smart camera 103 captures an image of the upper left side of the plastic ampoule 9. The image recognition system determines whether the scratches, foreign matter, or damaged bottle defects in the upper left side of the plastic ampoule 9 are within an acceptable range.

[0064] As the plastic ampoule 9 continues to be conveyed forward, it passes the conversion pulley 204 and is supported by the top conveyor belt 203 on the top of the plastic ampoule 9 and continues to be conveyed. When the plastic ampoule 9 enters the imaging area of ​​the fourth smart camera 104, the fourth smart camera 104 captures an image of the lower left side of the plastic ampoule 9. The image recognition system determines whether the scratches, foreign matter, or damaged bottle defects in the lower left side of the plastic ampoule 9 are within an acceptable range.

[0065] As the plastic ampoule 9 continues to be transported forward, it enters the imaging area of ​​the fifth smart camera 105. The fifth smart camera 105 captures an image of the lower right side of the plastic ampoule 9. The image recognition system determines whether the scratches, foreign matter, or damaged bottle defects in the lower right side of the plastic ampoule 9 are within an acceptable range.

[0066] As the plastic ampoule 9 continues to be transported forward, it enters the imaging area of ​​the sixth smart camera 106. The sixth smart camera 106 captures an image of the bottom area of ​​the plastic ampoule 9. The image recognition system determines whether the scratches, foreign matter, or damaged bottle defects on the bottom area of ​​the plastic ampoule 9 are within an acceptable range.

[0067] The plastic ampoule bottle 9 continues to be conveyed out of the area by the bottle clamping conveyor belt 2 to the bottle discharging connecting line 4. The image recognition situation collected by multiple intelligent cameras is integrated to determine whether the plastic ampoule bottle 9 flowing out is qualified. If the plastic ampoule bottle 9 is determined to be unqualified, when the plastic ampoule bottle 9 reaches the area of ​​the rejection cylinder 8, the rejection cylinder 8 extends and pushes the unqualified product into the chute 7. The chute 7 slides the unqualified bottle into the receiving box 6, and the qualified plastic ampoule bottle 9 is conveyed to the subsequent process to realize the automatic detection of the plastic ampoule bottle 9.
