Technical Field

[0001] The utility model relates to the technical field of visual quality inspection, in particular to a visual sorting device for a silicone piston of a blood sample collector. Background Technique

[0002] Arterial blood gas analysis has a wide range of clinical applications and is mainly used to evaluate the respiratory function and blood acid-base balance of the human body, providing important reference indicators for formulating diagnosis and treatment plans for critically ill patients. During the process of blood gas analysis, the arterial blood collector plays a crucial role. The arterial blood collector usually consists of a syringe, a needle, a push rod, and a silicone piston thereon. The quality of the silicone piston is particularly important, so it needs to undergo multiple quality inspections before it can be put into use.

[0003] However, the existing detection equipment usually can only perform single-quality detection, and a qualified silicone piston needs to pass multiple detections. Therefore, multiple detection equipment needs to be combined for detection, resulting in a large occupied area of the pipeline production line. Moreover, after the detection, the silicone pistons need to be graded and sorted, which requires another set of pipeline production line. There are problems of large floor area, complex equipment, and high energy consumption. Content of the Utility Model

[0016] Beneficial effects

[0017] The driving motor can drive the turntable to rotate, enabling the silicone piston to pass through multiple vision detection components in sequence. By adjusting the position of the light-emitting plate, the first detection component can make the light beam enter the opening on the front of the silicone adjustment buckle, the second detection component can make the light beam reflect the contour of the silicone piston, and the light-emitting plate of the third detection component can be used by the camera to identify the situation of the slot at the tail end of the silicone piston, and classify the silicone piston according to the image information. When the classified silicone piston reaches in front of the designated material distribution pipe of the equipment, the air nozzle is activated and can blow it into a specific material distribution pipe to complete the collection of silicone pistons of the same level. Only the turntable contacts the silicone piston during the whole process of detection, ensuring that it is not contaminated. It has the effect of achieving multiple detections with one rotation, and can achieve real-time sorting according to the results immediately after detection, and has the advantages of small floor area and lower power consumption.

[0039] Embodiment

[0040] As Figures 1 to 14 , a visual sorting device for silicone pistons of a blood sample collector, comprising a box body. A table is provided in the middle of the box body, on which a visual sorting module 1 is provided. A window is provided on one side of the box body, and a feeding track 2 can be placed into the window to facilitate the connection between the visual sorting device for mask silicone pistons and other devices. After the device is started, the feeding track 2 can transport the silicone pistons into the visual sorting module 1. An outlet pipe 3 is provided at the bottom end of the front surface of the box body, and the outlet pipe 3 is connected to the visual sorting module 1. The visual sorting module 1 is provided with a rotating part 4 for receiving and moving materials. A visual detection part 5 and a material sorting part 6 are provided on the side of the rotating part 4. The material sorting part 6 is connected to the outlet pipe 3. One end of the feeding port of the feeding track 2 is connected to the rotating part 4. The rotating part 4 is provided with a transparent turntable 7. After the materials leave the feeding track 2, they will be received by the turntable 7. A driving motor 8 is connected to the bottom of the turntable 7. The driving motor 8 can drive the turntable 7 to rotate, so that the materials change positions and are detected from multiple angles by the visual detection part 5. The specific detection items are: whether there is a blockage in the opening on the front surface of the silicone adjustment buckle; whether the outer wall contour of the silicone piston is round; whether the slot at the tail end of the silicone piston is smooth and clean. The material sorting part 6 can classify the silicone pistons according to the detection results of the visual detection part 5. The specific grades are: excellent, good, qualified, and unqualified. According to the grades of the silicone pistons, the materials are discharged at different positions, so that the silicone pistons enter different outlet pipes 3 to achieve the sorting of the silicone pistons.

[0041] Preferably, a positioning part 9 is further provided in front of the outlet of the feeding track 2. The positioning part 9 is provided with a support platform, and a U-shaped bracket 10 is connected to the front end of the support platform. An infrared sensor is provided on the U-shaped bracket 10. The turntable 7 is in a circular ring shape. The feeding track 2 is tangent to the turntable 7. A plurality of visual detection parts 5 are provided, and each detection part 5 is provided with a camera. The camera can be located above the turntable 7 or below the turntable 7.

[0042] By adopting the above technical solution, the U-shaped bracket 10 can place the infrared sensor inside the inner ring and outside the outer ring of the turntable 7, and the U-shaped bracket 10 reduces the height of the infrared sensor, so that the infrared rays emitted by the infrared sensor can be projected onto the middle of the silica gel piston. When the silica gel adjustment buckle is carried by the turntable 7 past the positioning member 9, the silica gel piston can block the infrared rays emitted by the outer sensor, enabling the infrared sensor to recognize the time when the infrared rays are blocked. Combining with the rotation speed of the turntable, the time for the silica gel piston to enter the visual inspection member 5 and the material distribution member 6 can be obtained, realizing precise detection and blanking work.

[0043] Preferably, a waste collection member 11 is further provided on the outermost side of the material distribution member 6. The waste collection member 11 is provided with a waste bucket 12 for collecting waste. The front end of the waste bucket 12 is in a stepped shape, facilitating the front end of the waste bucket 12 to be placed under the turntable 7. The waste collection member 11 is further provided with a blocking piece 13. The blocking piece 13 is arranged at the upper end of the turntable 7 and is inclined between the waste bucket 12 and the turntable 7. There is a gap not higher than the material between the blocking piece 13 and the turntable 7.

[0044] By adopting the above technical solution, when the visual inspection member 5 determines that the silica gel piston is unqualified, when the silica gel piston passes through the material distribution member 6, the material distribution member 6 does not start. The silica gel piston will continue to move towards the waste collection member 11 along with the turntable 7. When it moves to the blocking piece 13, the silica gel piston will be blocked. And because the turntable 7 continues to rotate, and the blocking piece 13 provides resistance in the inclined direction, the silica gel piston will move towards the waste bucket 12 and will eventually fall into the waste bucket 12.

[0045] Preferably, the material distribution member 6 is provided with a material distribution pipe 14 connected to the discharge pipe 3 and a jet nozzle 15. The front end of the material distribution pipe 14 is in a stepped shape, enabling the front end of the material distribution pipe 14 to be placed under the turntable 7. A placement table 16 is provided on the material distribution pipe 14. The jet nozzle 15 is arranged on the placement table 16. The jet nozzle 15 is connected to an air pump through a hose. The jet nozzle 15 is inclined, and the air outlet faces the material distribution pipe 14.

[0046] By adopting the above technical solution, the silica gel piston after being detected will enter the material distribution member 6 along with the turntable 7. The staff can set the number of the material distribution pipe 14 and the jet nozzle 15 according to the grading situation. When the silica gel piston reaches in front of the jet nozzle 15 corresponding to the grade, the jet nozzle 15 starts, blowing the silica gel piston into the material distribution pipe 14 aligned with the jet nozzle 15 to complete the sorting and blanking work.

[0047] Preferably, the placing table 16 is arc-shaped, the placing table 16 and the turntable 7 are coaxial, a plurality of material distribution pipes 14 are provided, and they are circumferentially arrayed under the placing table 16. The number of the air jet nozzles 15 is the same as that of the material distribution pipes 14. The discharge pipe 3 has a corner, and a recessed cabinet 17 is provided on the side wall of the box body. The material distribution pipe 14 is arranged on the inner wall of the top end of the recessed cabinet 17, the discharge pipe 3 is arranged under the top wall of the recessed cabinet 17, the blocking piece 13 is also arranged on the placing table 16, and a fixed groove 18 for the waste bin 12 to slide into is further provided under the turntable 7.

[0048] By adopting the above technical solution, the placing table 16 is arc-shaped, which enlarges the distance between the air jet nozzles 15 of different grades and avoids mutual interference affecting the blanking. The recessed cabinet 17 is recessed inward into the box body to form a space for placing the discharge pipe 3. The corner provided on the discharge pipe 3 can enable the discharge pipe 3 to avoid the bottom wall of the recessed cabinet 17, and at the same time can play a guiding role for the falling silicone pistons, so that they fall into the collection bucket provided at the bottom of the discharge pipe 3. The waste bin 12 is of a detachable design, which is convenient for the staff to clean the waste silicone pistons inside. The fixed groove 18 can assist the staff to accurately place the waste bin 12. The two cooperate to enable the waste bin 12 to be inserted and pulled out by pushing / pulling.

[0049] Preferably, the visual inspection part 5 is provided with a first inspection part 19, a second inspection part 20 and a third inspection part 21. The visual inspection part 5 is provided with a support table and a camera. The first inspection part 19 is arranged on one side of the positioning part 9. The table surface is provided with a first slot 22 for placing the first inspection part 19. The second inspection part 20 is arranged on the table surface. The table surface is provided with a second slot 23 for placing the third inspection part 21.

[0050] By adopting the above technical solution, the number of inspection parts provided in the visual inspection part 5 can be adjusted according to actual needs. In this application, the first inspection part 19 is used to detect whether the opening on the front of the silicone adjustment buckle is blocked. The second inspection part 20 is used to detect whether the outer wall contour of the silicone piston is round. The third inspection part 21 is used to detect whether the slot at the tail end of the silicone piston is smooth and tidy. All three are visually inspected through the camera.

[0051] Preferably, the camera of the first inspection part 19 extends out from the first slot 22 and is located under the turntable 7. The camera of the first inspection part 19 is a hole-blocking detection camera 24. The first inspection part 19 is further provided with a light-emitting board 25. The light-emitting board 25 is located above the turntable 7 and is coaxial with the hole-blocking detection camera 24.

[0052] By adopting the above technical solution, the positioning member 9 records the position of the silicone piston on the turntable and calculates the time when it enters the first detecting member 19. When the silicone piston enters the first detecting member 19, the light-emitting plate 25 irradiates the silicone piston from top to bottom, enabling the light to pass through the opening at the upper end of the silicone piston. The plug-hole detecting camera 24 identifies the area of the opening at the upper end of the silicone piston. If it is flat inside without burrs and blockages, it is excellent; if there are burrs inside without blockages, it is good; if there are burrs inside and the blocked area does not exceed the preset blocked area, it is qualified; if the blocked area inside is greater than or equal to the preset blocked area, it is unqualified.

[0053] Preferably, the camera and the positioning disc 26 provided in the second detecting member 20 are both arranged at the upper end of the turntable 7. The camera is arranged at the upper end of the positioning disc 26. The camera of the second detecting member 20 is the first hub detecting camera 27. The second detecting member 20 is further provided with a light-emitting plate 25. The light-emitting plate 25 is placed below the turntable 7. The first hub detecting camera 27, the positioning disc 26 and the light-emitting plate 25 are located on the same axis line.

[0054] By adopting the above technical solution, the positioning member 9 records the position of the silicone piston on the turntable and calculates the time when it enters the second detecting member 20. When the silicone piston is exactly located in the middle of the positioning disc 26 provided in the second detecting member 20, the light-emitting plate 25 of the second detecting member 20 lights up, and the light irradiates from bottom to top. The silicone piston will block the light, making the contrast between its outer wall contour and the light-emitting plate 25 bright and dark, facilitating the first hub detecting camera 27 to identify whether the contour of the side wall of the silicone piston is round and flat, and scoring according to the roundness and flatness degree.

[0055] Preferably, the camera provided in the third detecting member 21 is arranged in the second slot 23 and is the second hub detecting camera 28. The positioning disc 26 provided in the third detecting member 21 is located above the camera and below the turntable 7. The third detecting member 21 is further provided with a light-emitting plate 25. The light-emitting plate 25 is placed above the turntable 7. The second hub detecting camera 28, the positioning disc 26 and the light-emitting plate 25 are located on the same axis line.

[0056] By adopting the above technical solution, the positioning member 9 records the position of the silicone piston on the turntable and calculates the time when it enters the third detecting member 21. When the silicone piston is exactly located in the middle of the positioning disc 26 provided in the third detecting member 21, the light-emitting plate 25 of the third detecting member 21 lights up, and the light irradiates from top to bottom, causing the silicone piston to block the light. Since the thickness of the tail slot of the silicone adjustment is different from that of other parts, the light transmission degree is different, and the slot is inclined, which will cause the light to refract. Therefore, a bright and dark contrast is formed between the slot part and the bottom of the silicone adjustment, facilitating the second hub detecting camera 28 to identify whether the contour of the slot of the silicone piston is flat, and scoring according to the flatness degree.

[0057] Preferably, a guide plate 29 is further provided at the upper end of the discharge port of the feeding track 2. The guide plate 29 is tangent to the turntable 7 and is inclined to the feeding track ②. The number of the distribution pipes 14 and the discharge pipes 3 is three.

[0058] By adopting the above technical solution, after the silicone piston conveyed by the feeding track 2 slides out, it will fit with the guide plate 29. Under the action of the rotating force of the turntable 7, it slides into the middle of the turntable 7 along the guide plate 29 and accurately passes through the middle of each positioning plate 26. The distribution pipes 14 are, in a counterclockwise direction, the excellent product feeding area, the good product feeding area, and the qualified product feeding area in sequence.

[0059] Working principle: The feeding track 2 feeds the silicone piston under the visual inspection part 5 and drives the motor 8 to drive the turntable 7 to rotate, so that the silicone piston is sequentially detected by the first detection part 19, the second detection part 20, and the third detection part 21. After passing the detection, it enters the distribution part 6. According to the detection result of the visual inspection part 5, it is determined whether the silicone piston is discharged in the distribution part 6. When discharging, the air nozzles 15 of the corresponding grade are activated to blow the silicone piston into the distribution pipes 14 of the corresponding grade. If the material is unqualified, the distribution part 6 is not activated, and the turntable 7 conveys the silicone piston to the waste bin 12, and through the blocking piece 13, the silicone piston falls into the waste bin 12.

[0060] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
