When the carrier is in the third inspection position, the reflector is located directly below the information code. Due to the height of the third inspection mechanism, it is not suitable to set the lens of the fourth camera upward directly below the third inspection device. Therefore, the fourth camera is set below the third inspection position and on one side of the reflector. The fourth camera is placed horizontally, and the reflector reflects the information code image into the fourth camera. At the same time, in order to make the image captured by the fourth camera clearer, a third light source can be set above the reflector.

[0023] In an implementable scheme, the material channel is located in front of the detection part; in the vertical direction, the material channel is inclined, and the upper port of the material channel is higher than its lower port, so as to transport the finished packaged products from top to bottom into the carrier; the material channel includes a first side plate and a second side plate arranged at intervals, and a bottom plate connected to the bottoms of the first side plate and the second side plate respectively; a guide plate is arranged in the material channel, and in the vertical direction, the guide plate is inclined, and the upper end of the guide plate is close to the first side plate, and the lower end of the guide plate is close to the second side plate, so as to guide the finished packaged products conveyed to the guide plate in a vertical state to a state with its transparent surface facing upward, and fall on the bottom plate; along the conveying direction of the material channel, the guide plate is inclined, and the distance between the end of the guide plate close to the upper port of the material channel and the first side plate is L1, and the distance between the end of the guide plate close to the lower port of the material channel and the first side plate is L2, and L1-L2>0.

[0024] In this embodiment, the packaged finished product to be inspected can be placed in the material channel in a vertical state, and the lower edge of the packaged finished product that falls vertically onto the guide plate first contacts the guide plate, and then, under the guidance of the guide plate, its lower edge slides toward the second side plate, and finally the lower edge of the packaged finished product first contacts the bottom plate, at which time the upper edge of the packaged finished product also slides in contact with the guide plate, and finally the packaged finished product slides onto the bottom plate and presents a transparent surface facing the bottom plate, and the packaged finished product slides from top to bottom along the material channel into the carrier on the conveyor line. In addition, the guide plate is set to be inclined in the material channel transmission direction, so that the packaged finished product can generate a component speed along the material channel transmission direction when sliding in contact with the guide plate, so that after the packaged finished product leaves the guide plate, the packaged finished product can slide down along the material channel at a certain initial velocity to avoid the packaged finished product being stranded on the material channel.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] like Figure 1 - Figure 3 As shown, the infusion set packaging detection device provided by the utility model may include: a detection part, a conveying line 100 and a sorting mechanism 600.

[0061] Among them, Figure 1 and Fig. 9 As shown, the transmission line 100 may include a chain transmission module or a belt transmission module. In this embodiment, the transmission line 100 may include a chain transmission module, which includes two parallel chains 120, and two sprocket wheels 130 are rotatably connected at both ends of the two chains 120, one of the sprocket wheels 130 is connected to a motor 140 through a belt, and the motor 140 drives the sprocket wheel 130 to rotate after starting, thereby driving the chain 120 to move. The two ends of the carrier 110 are respectively connected to the two chains 120.

[0062] like Figure 4 and Figure 8As shown, the carrier 110 is used to hold the packaged finished product 700. The carrier 110 can be trough-shaped or box-shaped. The detection part and the sorting mechanism 600 are arranged in sequence along the transmission direction of the conveyor line 100. After the conveyor line 100 is started, the conveyor line 100 drives the carrier 110 to pass through the detection part and the sorting mechanism 600 in sequence.

[0063] The detection unit can collect image information of detection features of the packaged product 700 and determine whether the packaged product 700 is qualified based on the image information, wherein the detection features include at least one of the infusion set accessories, welding wires and information codes. Image recognition technology belongs to the existing technology, such as CCD detection.

[0064] The sorting mechanism 600 is arranged at the rear of the detection part, and can separate qualified and unqualified packaged products 700, and can push the packaged products 700 out from the open end of the carrier 110 by pushing and pulling; in other feasible schemes, the packaged products 700 can also be taken out directly from the top, for example, by using a vacuum suction cup to grab the packaged products 700 from the vertical direction.

[0065] The detection principle is as follows: the packaged finished product 700 to be detected can be placed in the carrier 110 of the conveyor line 100, and the packaged finished product 700 moves forward to the detection part under the conveyance of the conveyor line 100. The detection part can collect image information of the detection features on the packaged finished product 700, complete the detection through image recognition technology, and thus determine whether the packaged finished product 700 is qualified. After the packaged finished product 700 is transmitted from the detection part with the carrier 110, the sorting mechanism 600 sorts out the qualified or unqualified packaged finished products 700 from the packaged finished products 700 according to the detection results of the detection part.

[0066] The advantages are as follows: Different from manual inspection, the inspection device provided by the utility model adopts automatic transmission combined with image recognition inspection technology, and finally the sorting mechanism 600 sorts qualified and unqualified packaged finished products 700 to complete the inspection, which greatly improves the inspection efficiency and avoids the problem of large inspection errors caused by human factors.

[0067] The detection features proposed in this embodiment may be infusion set accessories, welding wires and information codes. The device may detect only one of them, or may select two or three for detection, and may be adjusted according to actual production.

[0068] In this embodiment, all three detection features are tested, and as long as one of them fails, the packaged product 700 will be judged as unqualified.

[0069] Specifically, the detection unit may include a first detection mechanism 200, a second detection mechanism 300, and a third detection mechanism 400, and the first detection mechanism 200, the second detection mechanism 300, and the third detection mechanism 400 may be arranged in sequence from front to back along the transmission direction. The conveyor line 100 drives the carrier 110 to pass through the first detection position in the first detection mechanism 200, the second detection position in the second detection mechanism 300, and the third detection position in the third detection mechanism 400. The same packaged finished product 700 is subjected to image recognition detection at the first detection position, the second detection position, and the third detection position, respectively.

[0070] like Figure 4 As shown, the first detection mechanism 200 may include a gantry 210, which is set up above the conveyor line 100 to collect information on infusion set accessories from top to bottom. It should be noted that the upper surface of the infusion set package on the carrier 110 is transparent, and the internal situation can be directly seen. The gantry 210 is connected to the first image acquisition module, and the first image acquisition module can move horizontally (in the width direction of the conveyor line 100) and vertically relative to the gantry 210 to adjust the shooting position and focus. The first image acquisition module is used to capture the image of the infusion set accessories in the packaged product 700, and the first detection mechanism 200 can determine whether the packaged product 700 is qualified based on the image of the infusion set accessories.

[0071] For example, the first image acquisition module may include a first camera 220 and a second camera 230, both of which are located above the first detection position, the first camera 220 is used to acquire an image of the venous needle assembly, and the second camera 230 is used to acquire an image of the flow regulator assembly. The first detection mechanism 200 can determine whether the venous needle assembly and the flow regulator assembly are assembled in place, whether the venous needle assembly and the flow regulator assembly are missing, and whether the venous needle assembly and the flow regulator assembly are wound into the bag in place by image comparison. Among the above judgments, as long as one of the judgments does not meet the requirements, the packaged product 700 is judged to be unqualified.

[0072] Furthermore, in order to make the image information collected by the first camera 220 and the second camera 230 clearer, the bottom surface of the carrier 110 is set to be transparent, and the first light source is used to illuminate from below, so that the accessories inside the packaged product 700 can be clearer and the image collection quality can be improved.

[0073] like Figure 5As shown, the second detection mechanism 300 may include a second image acquisition module, wherein the second image acquisition module may include a two-dimensional slide rail 310 and a third camera 320, the third camera 320 is connected to the free end of the two-dimensional slide rail 310, thereby changing the horizontal and vertical positions of the third camera 320, facilitating alignment of the welding line and focusing, and a second light source 330 is arranged next to the third camera 320 for supplementary light. The third camera 320 captures the image of the welding line in the packaged product 700, and the second detection mechanism 300 can judge whether the packaged product 700 is qualified based on the image of the welding line. Among them, the second detection mechanism 300 can judge whether the welding line of the packaged product 700 is complete and whether the material at the welding line is squeezed by image comparison. In the above judgment, as long as one of the judgments does not meet the requirements, the packaged product 700 is judged to be unqualified.

[0074] like Figure 6 As shown, the third detection mechanism 400 may include a third image acquisition module, and the third image acquisition module is used to acquire an image of the information code in the packaged product 700. The third detection mechanism 400 can judge whether the packaged product 700 is qualified according to the image of the information code. The third detection mechanism 400 can judge whether the position of the information code is correct and whether the information of the information code is correct and complete through image comparison. In the above judgments, as long as one of the judgments does not meet the requirements, the packaged product 700 is judged to be unqualified.

[0075] In this embodiment, the information code on the packaged product 700 to be inspected is set on the back of the package, that is, the side facing the bottom of the carrier 110. Therefore, the carrier 110 is set to be light-transmissive. The third image acquisition module includes a reflector 410 and a fourth camera 420. When the carrier 110 is in the third detection position, the reflector 410 is located directly below the information code. Due to the height of the third detection mechanism 400, it is not suitable to set the lens of the fourth camera 420 facing upward and directly below the third detection device. Therefore, the fourth camera 420 is set below the third detection position and on one side of the reflector 410. The fourth camera 420 is placed horizontally, and the reflector 410 reflects the information code image into the fourth camera 420 at a reflection angle of 45°.

[0076] In order to make the image captured by the fourth camera 420 clearer, a third light source, such as a ring light source 430 , may be arranged above the reflector 410 for supplementary light.

[0077] The detection part is divided into three parts to realize separate detection of different positions. On the one hand, it can realize the modular production of the detection device. On the other hand, it is also convenient for users to debug and avoid mutual interference among various detection mechanisms.

[0078] In this embodiment, Figure 8 , Fig.10 and Fig.11As shown, the infusion set packaging detection device further includes a material channel 500, which is located in front of the detection part; in the vertical direction, the material channel 500 is tilted, the upper end of the material channel 500 is higher than the lower end thereof, and the lower end of the material channel 500 faces the conveyor line 100, and the material channel 500 is used to transport the packaged finished product 700 to the carrier 110. The packaged finished product 700 falls from the upper end of the material channel 500 into the material channel 500, and then slides from top to bottom along the material channel 500 into the carrier 110 due to gravity. The material channel 500 can be trough-shaped or tubular-shaped, and a trough-shaped one is adopted in this embodiment.

[0079] The material channel 500 includes a first side plate 510 and a second side plate 520 which are arranged at intervals, and a bottom plate connected to the bottoms of the first side plate 510 and the second side plate 520 respectively; a guide plate 530 is arranged in the material channel 500. In this embodiment, the guide plate 530 is rectangular. In the vertical direction, the guide plate 530 is inclined, and the upper end of the guide plate 530 is close to the first side plate 510, and the lower end of the guide plate 530 is close to the second side plate 520, that is, the upper edge of the guide plate 530 is close to the first side plate 510, and the lower edge of the guide plate 530 is close to the second side plate 520. The inclined guide plate 530 is used to guide the finished package 700 which is conveyed to the guide plate 530 in a vertical state to a state where its transparent surface faces upward, and falls on the bottom plate.

[0080] like Fig.11 As shown, the packaged product 700 falls into the material channel 500 in a vertical state. In order to make the packaged product 700 fall onto the bottom plate of the material channel 500 with the transparent surface facing upward, and then slide into the carrier 110, a guide plate 530 is provided in the material channel 500. The guide plate 530 is tilted vertically upward. The lower edge of the packaged product 700 that falls vertically onto the guide plate 530 first contacts the guide plate 530, and then under the guidance of the guide plate 530, its lower edge slides toward the second side plate 520. Finally, the lower edge of the packaged product 700 first contacts the bottom plate, and at this time, the upper edge of the packaged product 700 also slides and contacts the guide plate 530. Finally, the packaged product 700 slides onto the bottom plate and presents a transparent surface facing upward. The guide plate 530 can realize the automatic flattening of the packaged product 700 on the bottom plate, avoiding manual intervention.

[0081] Further, such as Fig.10 As shown, along the transmission direction of the material channel 500, the guide plate 530 is inclined, the distance between the end of the guide plate 530 close to the upper port of the material channel 500 and the first side plate 510 is L1, the distance between the end of the guide plate 530 close to the lower port of the material channel 500 and the first side plate 510 is L2, and L1-L2>0.

[0082] In this embodiment, one end of the guide plate 530 close to the upper port of the material channel 500 is arranged approximately at the middle position of the upper port, and one end of the guide plate 530 close to the lower port of the material channel 500 is connected to the first side plate 510. The guide plate 530 is arranged to be inclined in the transmission direction of the material channel 500, so that the packaged finished product 700 can generate a component speed along the transmission direction of the material channel 500 when slidingly contacting the guide plate 530, so that after the packaged finished product 700 leaves the guide plate 530, the packaged finished product 700 can slide downward along the material channel 500 at a certain initial speed, so as to avoid the packaged finished product 700 being retained on the material channel 500.

[0083] like Figure 8 As shown, the lower end of the material channel 500 is provided with an openable and closable valve, and the valve may include a push rod and a first baffle 540, the push rod is fixedly connected to the material channel 500, and the movable end of the push rod is connected to the first baffle 540, and the first baffle 540 is driven to block the lower end of the material channel 500 to prevent the packaged finished product 700 from sliding toward the conveyor line 100. When the empty carrier 110 on the conveyor line 100 is aligned with the material channel 500, the first baffle 540 is opened, and the packaged finished product 700 slides out, and then the first baffle 540 is closed again to prevent two packaged finished products 700 from entering the same carrier 110, and the valve allows the packaged finished products 700 to enter the conveyor line 100 regularly.

[0084] The infusion set packaging detection device also includes a stop structure, which is fixed relative to the material channel 500. The stop structure may include a second baffle 550. Since the carrier 110 in this embodiment is groove-shaped and both ends are open, the stop structure and the material channel 500 are respectively arranged on opposite sides of the conveyor line. The second baffle 550 stops at one open end of the carrier 110, thereby blocking the packaged product 700 and preventing it from slipping out of the carrier 110.

[0085] The carrier 110 includes a groove bottom and two groove walls 111 connected to opposite sides of the groove bottom. The length direction of the carrier 110 is perpendicular to the transport direction of the conveyor line 100, and at least one of the opposite ends of the carrier 110 in the length direction is open; the sorting mechanism 600 includes a driving module and a toggle member, the toggle member is connected to the driving module, and the driving module drives the toggle member to move along the length direction of the carrier 110, so that when the packaged product 700 is detected as unqualified, the driving module drives the toggle member to push the packaged product 700 out of the opening.

[0086] like Figure 7As shown, the two groove walls 111 can play a limiting role to prevent the packaged finished products 700 that slide into the carrier 110 from rotating. When the carrier 110 containing unqualified packaged finished products 700 moves to the sorting mechanism 600, the conveyor line 100 can be paused, and the driving module can drive the toggle member to move along the length direction of the carrier 110, so as to push out the unqualified packaged finished products 700. After the toggle member leaves the carrier 110, the conveyor line 100 is started again to convey the qualified packaged finished products 700 to the front of the conveyor line 100. The driving module can be a push rod motor. In this embodiment, the driving module includes a conveyor belt 610, and the toggle member is a rack 620 connected to the belt surface of the conveyor belt 610.

[0087] In order to prevent the packaged product 700 from falling and being damaged, a guide structure can be provided on the falling path of the packaged product 700 to guide the packaged product 700 to fall into the storage bag or storage box, wherein the guide structure can be groove-shaped or tubular-shaped. In this embodiment, the guide structure includes a third baffle 630 and a fourth baffle 640, and the distance between the two gradually decreases from top to bottom.

[0088] Furthermore, both opposite ends of the carrier 110 in the length direction are open; the driving module can drive the toggle member to move forward and reversely along the length direction of the carrier 110, so as to push the packaged product 700 on the carrier 110 out from one open end of the carrier 110, or out from the other open end.

[0089] That is to say, the conveyor belt 610 can rotate forward or reverse, and unqualified storage bags and suspected unqualified storage bags are placed on both sides of the conveyor line 100 respectively. After detection by the detection unit, the toggle member will push the unqualified packaged finished product 700 to one side to open, and make it enter the unqualified storage bag; the toggle member will push the suspected unqualified packaged finished product 700 to the other side to open, and make it enter the suspected unqualified storage bag, thereby realizing the classified storage of the packaged finished products 700.
