[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-10 , the present invention provides a technical solution: A performance detection device for processing medical plastic buckets, including a first frame 1 and a second frame 2. The first frame 1 and the second frame 2 are arranged in parallel, and the second frame 2 is located outside the first frame 1 to provide the overall support effect required by the device.

[0019] As shown Figure 2-4 in the figure, a conveyor belt 3 is installed above the first frame 1, and an electrical cabinet 17 is installed inside the first frame 1. The driving components of the conveyor belt 3 are integrated inside the electrical cabinet 17 to achieve the two-way stable operation of the conveyor belt 3. And a PLC control system and a data processing module are installed in the electrical cabinet 17 to achieve precise control of the electrical components in the device and real-time visualization of the detection data. Among them, the end of the conveyor belt 3 far from the second frame 2 is the input end. A first extrusion assembly is installed above the conveyor belt 3. The first extrusion assembly includes a connecting block 4. The connecting block 4 is fixedly connected above the first frame 1 on both sides of the conveyor belt 3. A first cylinder 5 is installed below the connecting block 4. The first cylinder 5 is fixedly connected to one side of the first frame 1, and the output end of the first cylinder 5 is slidably connected inside the connecting block 4. A fixed disk 6 is fixedly connected to the output end of the first cylinder 5. The height adjustment of the fixed disk 6 is realized by the drive of the first cylinder 5. The fixed disk 6 is connected to the connecting block 4 by a bearing, so that the outer side of the disk body of the fixed disk 6 can rotate after being subjected to an external force.

[0020] A support plate 7 is installed on one side of the first frame 1 far from the connecting block 4. The same first cylinder 5 is installed below the support plate 7, so as to realize the height adjustment of the support plate 7. A fixed block 8 is fixedly connected above the support plate 7. A driven rod 9 is rotatably connected to the fixed block 8. The other end of the driven rod 9 is connected to a moving disk 10 by a bearing. A driving rod 11 is rotatably connected to the middle of the moving disk 10. A cover 12 is riveted above the support plate 7. A gear 13 is connected to the inside of the cover 12 by a rod and a bearing. A rack 14 is installed on one side of the gear 13. The gear 13 is meshed with the rack 14. One end of the rack 14 is hinged to the other end of the driving rod 11. A guide rail 141 is installed below the rack 14. The guide rail 141 is fixedly connected above the support plate 7, and the rack 14 is slidably connected inside the guide rail 141 to realize the displacement guiding of the rack 14. A displacement sensor is installed on the guide rail 141 to selectively read the displacement distance of the rack 14. A rotating motor 15 is fixedly connected to the middle of the gear 13 by a rod. The rotating motor 15 is installed above the cover 12. The rotation of the gear 13 is realized by the drive of the rotating motor 15 and the rack 14 is displaced, so as to control the telescopic of the driving rod 11, and the distance between the moving disk 10 and the fixed disk 6 is adjusted. Pressure sensors one and two are respectively integrated at the shaft ends of the fixed disk 6 and the moving disk 10 to feedback the extrusion load in real time.

[0021] Furthermore, an electromagnetic clutch is installed on the rotating motor 15, which cooperates with the gear 13 and the rack 14 to form a transmission structure to realize the intelligent switching between two working states: When the electromagnetic clutch is energized, it locks up. The rotating motor 15 drives the gear 13 for rigid transmission. The rack 14 makes precise displacement along the guide rail 141, and the moving disk 10 is controlled to approach the fixed disk 6 through the driving rod 11. When the electromagnetic clutch is de-energized and disengaged, the rack 14 is released from the constraint of the motor internal resistance. When an object passes between the fixed disk 6 and the moving disk 10, the two disks will actively expand, and the rack 14 will slide freely with the moving disk 10.

[0022] On one side of the first extrusion mechanism away from the input end of the conveyor belt 3, a second extrusion assembly 16 is installed. The second extrusion assembly 16 has the same structure as the first extrusion mechanism and is used for secondary extrusion operation. Above the conveyor belt 3, a medical plastic bucket 18 is provided. The medical plastic bucket 18 is accurately positioned and placed above the conveyor belt 3 by a manipulator, thereby improving the accuracy of subsequent detection.

[0023] Among them, the first cylinder 5 and the rotating motor 15 are both signal-connected to the electrical cabinet 17 to realize the process timing control of extrusion loading and data acquisition.

[0024] As Figure 1 shown, inside one side of the second frame 2, a camera 19 is fixedly connected. The camera 19 integrates image processing and infrared detection functions to realize the accurate positioning of the position of the medical plastic bucket 18 and the accurate detection of its temperature.

[0025] As Figure 5 、 Figure 6 shown, a driving motor one is installed on the top of the second frame 2. Two horizontal slide rails 20 are installed on the inner top of the second frame 2. The horizontal slide rails 20 are driven by the driving motor. A vertical slide rail 21 is fixedly connected to the sliding end of the horizontal slide rail 20. A second cylinder 22 is fixedly connected to the sliding end of the vertical slide rail 21. A pneumatic joint 23 is fixedly connected to the telescopic end of the second cylinder 22, which is used to realize the large-range displacement of the pneumatic joint 23 and the effect of quickly connecting with the medical plastic bucket 18. A connecting pipe is opened on one side of the pneumatic joint 23, and an air pump 24 is fixedly connected to the connecting pipe through a pipeline to realize the inflation effect inside the medical plastic bucket 18.

[0026] As Figure 7-9As shown in the figure, a baffle 25 is fixedly connected to the inner side of the second rack 2. An expansion slot 251 is formed on one side of the baffle 25, and a sliding slot 252 is formed in the middle of the baffle 25. A slider 28 is slidably connected inside the sliding slot 252. A connecting rod 26 is fixedly connected to the bottom of the slider 28, and the other end of the connecting rod 26 is fixedly connected to a clamping plate 27. The clamping plate 27 is designed with a microchannel heat sink and internal nickel-chromium heating wires, supporting segmented temperature control. The clamping plate 27 is located above the conveyor belt 3. A lead screw 29 is slidably connected to the middle of the slider 28 through threads. The lead screw 29 has a structure with opposite thread directions at both ends. The lead screw 29 is connected to the inner wall of the second rack 2 through bearings, and one end is fixedly connected to a second driving motor. A protective cover 30 is arranged outside the second driving motor. The protective cover 30 is fixedly connected to the outside of the second rack 2, realizing the wiring arrangement of electrical components and integrating the temperature control module of the clamping plate 27, and communicating with the PLC of the electrical cabinet 17. The clamping plate 27 is controlled by the second driving motor to move towards or away from each other, and the displacement distance is regulated by the rotation of the second driving motor, and is controlled according to the current size data of the medical plastic bucket 18, so that the clamping plate 27 directly clamps the medical plastic bucket 18 after displacement.

[0027] As Figure 10 shown, a flow valve 241 is installed on the pipeline of the air pump 24 for controlling the inflation amount inside the medical plastic bucket 18. A third pressure sensor 242 is connected to the flow valve 241 through a pipeline for feedback on the gas pressure situation inside the medical plastic bucket 18. The third pressure sensor 242 is fixedly connected to the pneumatic joint 23 through a pipeline, and this pipeline is integrated with a pressure relief valve 243 to prevent the medical plastic bucket 18 from bursting due to thermal expansion or accidental overpressure.

[0028] Embodiment 1; In this embodiment, the medical plastic bucket 18 is divided into upper and lower part regions with the same height for a preliminary compressive strength test on the medical plastic bucket 18.

[0029] Specifically, the medical plastic bucket 18 is accurately placed at the set position on the conveyor belt 3 by a robotic arm, and the conveyor belt 3 is driven to convey the medical plastic bucket 18 at the set running speed v. After the medical plastic bucket 18 is conveyed for a distance of L1, it reaches the first extrusion assembly. The fixed disk 6 and the moving disk 10 of the first extrusion assembly monitor the extrusion load in real time through pressure sensor one and pressure sensor two. The fixed disk 6 and the moving disk 10 of the first extrusion assembly are both at the lowest height, that is, the height at which the lower surfaces of the two disks are flush with the upper surface of the conveyor belt 3, to achieve extrusion of the lower part area of the medical plastic bucket 18. Driven by the rotation motor 15, the moving disk 10 continuously approaches the fixed disk 6 until the resultant force feedback by pressure sensor one and pressure sensor two reaches F1 (the maximum pressure that the medical plastic bucket 18 can withstand), and then stops. After the medical plastic bucket 18 slides out between the two disks, it continues to be conveyed for a distance of L2. At this time, the conveyor belt 3 stops running, and the position of the bucket mouth of the medical plastic bucket 18 is located by the camera 19. It is set that after traveling the distances of L1 and L2, the coordinates of the bucket mouth of the medical plastic bucket 18 should be (x, y), and the coordinates of the bucket mouth located by the camera 19 are (x1, y1).

[0030] When x1 = x and y1 = y, it indicates that the medical plastic bucket 18 has accurately fallen on its preset position coordinates and has not moved.

[0031] When x1 ≠ x and y1 = y, it indicates that the medical plastic bucket 18 has undergone lateral extrusion deformation. At this time, the conveyor belt 3 is started to continue conveying the medical plastic bucket 18 for a distance of L3 to the second extrusion assembly 16. The extrusion pressure of the second extrusion assembly 16 is the same as that of the first extrusion assembly. The first cylinder 5 of the second extrusion assembly 16 drives the fixed disk 6 and the moving disk 10 of the second extrusion assembly 16 to be lifted to a height in the upper part area of the medical plastic bucket 18 and perform extrusion. After extrusion, the coordinates of the bucket mouth after accumulating the distance of L3 are (x2, y2). If x2 = x at this time, it indicates that the medical plastic bucket 18 has recovered from the deformation after secondary extrusion and has good elasticity, and the preliminary compressive strength test is qualified; if x2 ≠ x, it indicates that the medical plastic bucket 18 cannot recover from the deformation after secondary extrusion, and it is marked as unqualified in compressive performance and directly removed.

[0032] When x1 = x and y1 ≠ y, it indicates that the medical plastic bucket 18 has undergone longitudinal extrusion deformation. At this time, the conveyor belt 3 is stopped, and the first driving motor is controlled according to the coordinates (x1, y1). After the pneumatic joint 23 is accurately positioned above the bucket opening through the horizontal slide rail 20 and the vertical slide rail 21, the second cylinder 22 drives the pneumatic joint 23 to extend and insert it into the medical plastic bucket 18. Then, the air pump 24 is turned on to inflate the inside of the medical plastic bucket 18, and the inflation rate is controlled by the flow valve 241 to be v1 until the internal pressure is fed back by the third pressure sensor 242 to reach the designed maximum pressure value of the medical plastic bucket 18. If the internal pressure of the medical plastic bucket 18 cannot reach this pressure value, it indicates that the longitudinal deformation of the medical plastic bucket 18 cannot be restored. After marking it as unqualified in terms of compressive performance, it is directly removed.

[0033] If the internal pressure of the medical plastic bucket 18 reaches the highest pressure value that conforms to its product itself, then the conveyor belt 3 is continued to run for a distance of L2 at this time, and the medical plastic bucket 18 is transported to the second extrusion assembly 16 for secondary extrusion at the same height as the first extrusion. Then, the coordinates at the bucket opening are observed again through the camera 19 to check whether there is a deviation from (x1, y1). If there is a deviation, it indicates that the quality of the medical plastic bucket 18 is poor and it cannot withstand multiple extrusions; if there is no deviation, it indicates that there is a weak area in the medical plastic bucket 18. The defect position is recorded through the PLC control system and marked as a processing defect, and the preliminary compressive test is qualified.

[0034] When x1 ≠ x and y1 ≠ y, it indicates that the medical plastic bucket 18 has undergone severe extrusion deformation. At this time, it is directly marked as unqualified in terms of compressive performance and removed directly.

[0035] Through the above embodiments, the medical plastic buckets are divided into areas for compressive and deformation detection, realizing multi-dimensional and accurate determination of the horizontal, vertical, and severe deformation of the bucket body, achieving a full-process closed-loop control from deformation detection, performance determination, to defect traceability, and significantly improving the accuracy, compliance, and industrial adaptability of the compressive performance detection of the medical plastic bucket 18.

[0036] Embodiment 2; In this embodiment, the medical plastic buckets 18 that have passed the preliminary compressive test are subjected to airtightness detection, so as to improve the overall quality of the medical plastic buckets 18.

[0037] Specifically, the medical plastic bucket 18 that has passed the preliminary compressive test is conveyed to the end of the L3 stroke through the conveyor belt 3. The pneumatic connector 23 is precisely inserted into the bucket mouth to form a sealed space with the medical plastic bucket 18. The air pump 24 is started to introduce gas into the medical plastic bucket 18 at a constant flow rate, and the feedback gas flow is implemented through the flow valve 241. The internal gas pressure of the medical plastic bucket 18 is fed back through the pressure sensor three 242. After the maximum amount of gas that the medical plastic bucket 18 can hold has been fed back through the flow valve 241, the input is stopped. Under normal circumstances, the internal air pressure of the medical plastic bucket 18 after being filled with gas is set as P, and the internal air pressure size fed back through the pressure sensor three 242 is P1. At the same time, the pneumatic connector 23 is displaced synchronously with the medical plastic bucket 18 through the conveyor belt 3 through the longitudinal slide rail 21, so that while the medical plastic bucket 18 is being inflated, the secondary extrusion operation of the second extrusion assembly 16 is carried out (extruding the upper part area of the medical plastic bucket 18); When P1 = P, it indicates that the internal air pressure of the medical plastic bucket 18 is normal, the plastic bucket is not deformed, and the sealing performance is better; when P1 < P and P1 is constant, it indicates that the medical plastic bucket 18 has undergone minor deformation during the preliminary compressive test and has not been captured by the camera 19, which is marked as a processing defect; when P1 < P and P1 is not constant, it indicates that the medical plastic bucket 18 has cracked during the preliminary compressive test, and at this time it is marked as unqualified in compressive performance and directly removed.

[0038] Through the above embodiments, the airtightness and compressive performance during internal filling of the medical plastic bucket 18 are detected, the hidden defects missed in the compressive test are effectively identified, the full-process closed-loop control of inflation, extrusion, determination, and traceability is realized, the detection accuracy of the sealing performance and structural reliability of the medical plastic bucket is significantly improved, and it is ensured that the product meets the strict standards of medical packaging.

[0039] Embodiment Three; In this embodiment, in order to meet the medical grade level, medical supplies must be subjected to high-temperature disinfection operations. Therefore, the medical plastic bucket 18 is heated to detect the high-temperature resistance performance of the medical plastic bucket 18.

[0040] After the medical plastic bucket 18 that has passed the secondary compressive and airtightness tests and the pneumatic connector 23 synchronously pass through the L4 stroke, the barrel body falls within the range of the clamping plate 27. At this time, the bucket mouth is exposed outside the baffle 25 through the expansion slot 251. At this time, the drive motor two controls the screw rod 29 to rotate, so that the clamping plate 27 moves towards each other and clamps the medical plastic bucket 18. After clamping, the pneumatic connector 23 is driven to loosen, and the pneumatic connector 23 is pulled out from the bucket mouth by driving the contraction of the second cylinder 22. After being pulled out, the heating wire inside the clamping plate 27 starts to heat up. The heating time is set as t. After t time, the temperature of the medical plastic bucket 18 itself reaches the temperature required for high-temperature disinfection of medical supplies. At this time, the same compressive performance and airtightness tests are carried out on the medical plastic bucket 18 again.

[0041] Specifically, the pneumatic connector 23 is inserted again, and the medical plastic barrel 18 is inflated. At this time, the pressure relief valve 243 is opened to prevent the barrel body from being broken due to thermal expansion, and it is reversely transported to the second extrusion assembly 16 through the conveyor belt 3. At this time, the electromagnetic clutch of the rotary motor 15 is powered off and disengaged, and the medical plastic barrel 18 opens the two plates. At this time, the displacement distance of the rack 14 is read by the displacement sensor, so as to feedback whether there is thermal expansion in the lower part, and then drive the first cylinder 5 to raise the second extrusion assembly 16, so as to feedback whether there is thermal expansion in the upper part. If there is, it indicates that the high temperature resistance of the medical plastic barrel 18 is poor, and it is rejected; if not, it indicates that the high temperature resistance of the medical plastic barrel 18 is qualified and passes the performance test.

[0042] Through this embodiment, high-temperature heating is adopted to simulate the medical disinfection environment. After the medical plastic barrel 18 is heated to the disinfection temperature by constant temperature using the splint 27, reverse conveying detection is performed in combination with the protection mechanism of the pressure relief valve 243. The thermal expansion deformation of the barrel body is measured by the extrusion assembly that is disconnected by power failure, and the air tightness and pressure resistance are re-measured to accurately determine the high-temperature resistance of the plastic barrel, eliminate unqualified products with thermal deformation, and ensure that it meets the reliability requirements of medical-grade high-temperature disinfection.
