[0045] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0046] First, as Figure 1 and Figure 2 As shown, the present application provides a non-PVC infusion bag defect detection system, comprising:

[0047] The conveying mechanism 1 is used to convey the infusion bag 10 to be inspected;

[0048] The unloading mechanism 2 is arranged on one side of the conveying mechanism 1;

[0049] The defect foreign body detection component 3 is arranged above the conveying mechanism and is used to detect whether the infusion bag 10 to be inspected conveyed by the conveying mechanism 1 is qualified;

[0050] The packaging channel 4 is arranged below the unloading mechanism 2;

[0051] The recovery channel 5 is arranged below the unloading mechanism 2;

[0052] The control module 6 is connected to the defective foreign body detection component 3 and the unloading mechanism 2, and is used to control the unloading mechanism 2 to send the qualified infusion bags 10 to be inspected to the packaging channel 4 and send the unqualified infusion bags 10 to be inspected to the recycling channel 5.

[0053] Specifically, the defect foreign body detection component 3 can be set on the conveying mechanism 1, or can be set on one side of the conveying mechanism 1, or can be set at other positions that can detect the infusion bag 10 to be inspected on the conveying mechanism 1.

[0054] More specifically, when the non-PVC infusion bag defect detection system is working, the control module 6 can control the conveying mechanism 1 and the unloading mechanism 2 to operate synchronously, so that the unloading mechanism 2 can unload the infusion bag 10 to be inspected on the conveying mechanism 1 while the conveying mechanism 1 conveys the infusion bag 10 to be inspected, so as to realize the synchronization of the unloading process and the conveying process, thereby improving the detection efficiency; and the control module 6 can control the defective foreign matter detection component 3 to detect whether the infusion bag 10 to be inspected is qualified, and can control the unloading mechanism 2 to classify and unload the infusion bags 10 to be inspected that have completed the inspection, so as to realize unmanned inspection, thereby improving the detection efficiency, saving labor costs and reducing the risk of pollution.

[0055] The present application provides a non-PVC infusion bag defect detection system that can synchronize the unloading process and the conveying process, thereby improving detection efficiency, saving labor costs and reducing contamination risks.

[0056] like Figure 5 As shown, in some preferred embodiments, the conveying mechanism 1 includes a circular rail conveyor.

[0057] In this embodiment, the non-PVC infusion bag defect detection system of the present application is provided with a conveying module including a circular rail conveyor, which can realize the conveyance of the infusion bag 10 to be inspected.

[0058] Preferably, the track of the circular rail conveyor is arranged horizontally.

[0059] In some preferred embodiments, the unloading mechanism 2 includes:

[0060] A manipulator 21 is used to grab or place the infusion bag 10 to be inspected;

[0061] The horizontal driving mechanism 22 is connected to the manipulator 21 and is used to drive the manipulator 21 to move horizontally so that the end of the manipulator 21 moves to above the conveying mechanism 1, the packaging channel 4 or the recycling channel 5;

[0062] The vertical drive mechanism 23 is connected to the horizontal drive mechanism 22 and is used to drive the horizontal drive mechanism 22 to move up and down to drive the manipulator 21 to move up and down;

[0063] When the robot arm 21 is raised to the highest position, it is higher than the conveying mechanism 1 , the packaging channel 4 and the recycling channel 5 .

[0064] Specifically, the vertical drive mechanism 23 can drive the horizontal drive mechanism 22 to rise and fall to drive the manipulator 21 to rise and fall, so that the manipulator 21 can be raised to a level above the conveying mechanism 1, the packaging channel 4 and the recovery channel 5. The horizontal drive mechanism 22 can drive the manipulator 21 to move horizontally so that its end is moved above the conveying mechanism 1, the packaging channel 4 or the recovery channel 5, so that the manipulator 21 can grab or place the infusion bag 10 to be inspected to complete the unloading.

[0065] In this embodiment, the non-PVC infusion bag defect detection system of the present application is provided with a manipulator 21 , a horizontal drive mechanism 22 and a vertical drive mechanism 23 , which can realize unloading of the infusion bag 10 to be inspected.

[0066] In some preferred embodiments, the end of the manipulator 21 has a suction cup 211 facing downward.

[0067] In this embodiment, the non-PVC infusion bag defect detection system of the present application is provided with a suction cup 211, which enables the manipulator 21 to perform a sucking or loosening action on the infusion bag 10 to be inspected, thereby enabling the unloading of the infusion bag 10 to be inspected.

[0068] In some preferred embodiments, the horizontal drive mechanism 22 and the vertical drive mechanism 23 include servo motors.

[0069] In this embodiment, the non-PVC infusion bag defect detection system of the present application is provided with a servo motor, which can move the manipulator 21 up and down and can also drive the manipulator 21 to move horizontally.

[0070] In some preferred embodiments, the non-PVC infusion bag defect detection system further includes:

[0071] The display screen 7 is connected to the control module 6 and is used to display one or more of the conveying mechanism speed information, the manipulator speed information and the manipulator height information.

[0072] Specifically, the conveying mechanism 1 speed information represents the speed of the conveying mechanism 1 , the manipulator speed information represents the speed of the horizontal displacement of the manipulator 21 , and the manipulator height information represents the height of the manipulator 21 .

[0073] More specifically, since the unloading mechanism 2 needs to run at a specific speed, and the manipulator 21 needs to move horizontally at a specific speed and reach a specific height in order to achieve synchronization of the unloading process and the conveying process, in this embodiment, the non-PVC infusion bag defect detection system of the present application is provided with a display screen 7, which can display the conveying mechanism speed information, manipulator speed information and manipulator height information in real time, so that the operator can confirm in real time whether the conveying mechanism 1 and the unloading mechanism 2 are operating normally.

[0074] In some preferred embodiments, the display screen 7 is a touch screen.

[0075] Specifically, since the display screen 7 is a touch screen, the operator can interact with the system through the display screen 7. For example, when the conveying process and the unloading process are not carried out normally in synchronization, the operator can control the control module 6 based on the display screen 7 to complete tasks such as controlling the horizontal drive mechanism 22 to adjust the speed of the horizontal displacement of the manipulator 21 or controlling the vertical drive mechanism 23 to adjust the height of the manipulator 21. Therefore, in this embodiment, the non-PVC infusion bag defect detection system of the present application facilitates the operator to interact with the system, so that the control module 6 can receive the operator's instructions through the display screen 7 to complete the corresponding tasks.

[0076] like Figure 4 As shown, in some preferred embodiments, the non-PVC infusion bag defect detection system further includes:

[0077] An image acquisition mechanism 8, for acquiring an image of the infusion bag 10 to be inspected;

[0078] The type recognition module 9 is electrically connected to the image acquisition mechanism 8 and is used to identify the type information of the infusion bag 10 to be inspected based on the image;

[0079] The control module 6 includes:

[0080] The first judgment module 61 is electrically connected to the type recognition module 9, and is used to judge whether the type information is consistent with the type information to be detected, and output a first judgment result for triggering the defect foreign matter detection component 3 to operate when the type information is consistent with the type information to be detected.

[0081] Specifically, the image acquisition mechanism 8 can be arranged on the conveying mechanism 1, or can be arranged at other locations capable of acquiring images of the infusion bag 10 to be inspected.

[0082] More specifically, the type information of the infusion bag 10 to be inspected represents the type of the infusion bag 10 to be inspected, the type information to be inspected represents the type of the infusion bag that needs to be inspected, and the type of the infusion bag represents the specifications, materials and other properties of the infusion bag; the type information to be inspected can be information pre-existing in the system. In an embodiment where the display screen 7 is a touch screen, it can also be information selected by the user through the display screen 7 from multiple type information pre-existing in the system.

[0083] More specifically, the category information, the information on the category to be checked and the first judgment result can be data such as identification information or electrical signals, and the first judgment module 61 can be a logic gate circuit or other circuit that can output corresponding results based on whether the signal or information is consistent.

[0084] In this embodiment, the non-PVC infusion bag defect detection system of the present application can identify the type of the infusion bag 10 to be inspected, so that only specific types of infusion bags can be inspected, with high detection flexibility.

[0085] like Figure 3 As shown, in some preferred embodiments, the defect foreign body detection component 3 includes:

[0086] The light beam projection mechanism 31 is used to project a light beam toward the infusion bag 10 to be inspected;

[0087] The reflectivity measuring mechanism 32 is connected to the light beam projection mechanism 31 and is used to receive the light beam reflected by the infusion bag to be inspected 10 and measure the reflectivity information of each surface area of ​​the infusion bag to be inspected 10 based on the light beam reflected by the infusion bag to be inspected 10;

[0088] The control module 6 includes:

[0089] The second judgment module 62 is electrically connected to the reflectivity measurement mechanism 32, and is used to judge the size relationship between the reflectivity information and the standard reflectivity information, and output a second judgment result indicating whether there are defects in the appearance of the infusion bag 10 to be inspected and whether there are foreign objects inside.

[0090] Specifically, the reflectivity information of each surface area of ​​the infusion bag 10 to be inspected represents the reflectivity of each surface area of ​​the infusion bag 10 to be inspected, and the standard reflectivity information represents the reflectivity of a surface area of ​​an infusion bag of the same type as the infusion bag 10 to be inspected, free of external defects and free of internal foreign matter. The reflectivity information and the standard reflectivity information may be data such as identification information or electrical signals. The second judgment module 62 may be a circuit such as a logic gate circuit that outputs a corresponding result based on whether the signal or information is consistent. More specifically, the reflectivity measurement mechanism 32 may be a reflectivity meter that uses a photocell to receive reflected light and perform photoelectric conversion to measure reflectivity, or may be other devices capable of measuring reflectivity.

[0091] More specifically, when there are defects in the appearance of the infusion bag or foreign matter inside the bag, the reflectivity of the surface area of ​​the infusion bag where the appearance defects or the interior are located is different from the reflectivity of other surface areas without appearance defects and internal foreign matter. Therefore, in this embodiment, the non-PVC infusion bag defect detection system of the present application can judge whether there are defects on the outside and whether there are foreign matter inside based on the reflectivity information of the infusion bag 10 to be inspected, thereby realizing unmanned inspection.

[0092] In some preferred embodiments, the reflectivity measuring mechanism 32 includes a reflectivity meter.

[0093] In this embodiment, the non-PVC infusion bag defect detection system of the present application can detect the reflectivity information of the infusion bag 10 to be inspected.

[0094] In summary, the present application provides a non-PVC infusion bag defect detection system that can realize the simultaneous unloading process and the conveying process, improve the detection efficiency, save labor costs and reduce the risk of contamination.
