Description

Technical Field

[0001] The present invention relates to the technical field of medical plastic barrel production equipment, in particular to a performance detection device for processing medical plastic barrels. Background Art

[0002] Medical plastic barrels play a vital role in the medical field. They are widely used for the preparation, storage, and transportation of detergents and disinfectants, and are a key carrier for cleaning wards, operating rooms, and medical equipment. During procedures such as surgery, dressing changes, and wound care, they serve as temporary wastewater containers for flushing fluids and medical wastewater. The corrosion-resistant barrels can also serve as disinfectant immersion containers for instruments that cannot be autoclaved.

[0003] Regardless of the application scenario, the barrel's compressive strength directly impacts its ability to resist deformation during transport and stacking, while its sealing performance determines its ability to effectively isolate pathogens, chemical disinfectants, and contaminated liquids. If the barrel ruptures under pressure or its seal fails, virus-laden blood and cultures can leak out, exposing medical staff and cleaning staff to occupational exposure. Highly corrosive disinfectants can also erode the environment and damage sewage treatment systems. Contaminants can spread through contact or aerosols, leading to hospital-acquired infections and other serious consequences.

[0045] A second extrusion assembly 16 is mounted on the side of the first extrusion mechanism, away from the input end of the conveyor belt 3. This second extrusion assembly 16, identical in structure to the first extrusion mechanism, performs a secondary extrusion operation. A medical plastic barrel 18 is positioned above the conveyor belt 3. A robotic arm accurately positions the barrel above the conveyor belt 3, improving the accuracy of subsequent inspections.

[0046] Among them, the first cylinder 5 and the rotary motor 15 are both connected to the electrical cabinet 17 for signal connection, so as to realize the process timing control of extrusion loading and data collection.

[0047] like Figure 1As shown, a camera 19 is fixedly connected to the inside of one side of the second frame 2. The camera 19 integrates image processing and infrared detection functions to achieve precise positioning of the position of the medical plastic barrel 18 and accurate detection of its temperature.

[0048] like Figure 5 、 Figure 6 As shown, a driving motor 1 is installed on the top of the second frame 2, and two transverse slide rails 20 are installed on the inner top of the second frame 2. The transverse slide rail 20 is driven by the driving motor, and the sliding end of the transverse slide rail 20 is fixedly connected to the longitudinal slide rail 21, and the sliding end of the longitudinal slide rail 21 is fixedly connected to the second cylinder 22. The telescopic end of the second cylinder 22 is fixedly connected to the pneumatic joint 23, which is used to achieve a large range of displacement of the pneumatic joint 23 and a quick connection with the medical plastic barrel 18; a connecting pipe is provided on one side of the pneumatic joint 23, and an air pump 24 is fixedly connected to the connecting pipe through a pipeline to achieve the inflation effect of the inside of the medical plastic barrel 18.

[0049] like Figure 7-9 As shown, a baffle 25 is fixedly connected to the inner side of the second frame 2, an expansion groove 251 is opened on one side of the baffle 25, a slide groove 252 is opened in the middle of the baffle 25, a slider 28 is slidably connected inside the slide groove 252, a connecting rod 26 is fixedly connected to the bottom of the slider 28, and a splint 27 is fixedly connected to the other end of the connecting rod 26. The splint 27 adopts a microchannel heat spreader and an internal nickel-chromium heating wire design to support segmented temperature control. The splint 27 is located above the conveyor belt 3, and a screw rod 29 is slidably connected to the middle of the slider 28 through a thread. The screw rod 29 has a structure with opposite thread directions at both ends. The bearing is connected to the inner wall of the second frame 2, and one end is fixedly connected to the drive motor 2. A protective cover 30 is provided on the outside of the drive motor 2. The protective cover 30 is fixedly connected to the outside of the second frame 2 to realize the circuit arrangement of the electrical components and integrate the temperature control module of the splint 27. It is connected to the electrical cabinet 17PLC. The splint 27 is controlled by the drive motor 2 to realize the displacement of the two splints 27 toward or oppositely. The displacement distance is regulated by the rotation of the drive motor 2, and is controlled according to the current size data of the medical plastic barrel 18, so that the splint 27 directly clamps the medical plastic barrel 18 after displacement.

[0050] like Figure 10 As shown, a flow valve 241 is installed on the pipeline of the air pump 24 for controlling the amount of air inflated into the medical plastic barrel 18. The flow valve 241 is connected to a pressure sensor 3 242 through a pipeline for feedback of the gas pressure inside the medical plastic barrel 18. The pressure sensor 3 242 is fixedly connected to the pneumatic connector 23 through a pipeline. The pipeline is integrated with a pressure relief valve 243 to prevent the medical plastic barrel 18 from rupturing due to thermal expansion or accidental overpressure.

[0051] Embodiment 1;

[0052] In this embodiment, the medical plastic barrel 18 is divided into two regions, an upper region and an lower region, and the two regions have the same height, and a preliminary compressive strength test is performed on the medical plastic barrel 18.

[0053] Specifically, the medical plastic barrel 18 is accurately placed at the set position on the conveyor belt 3 by the manipulator, and the conveyor belt 3 is driven to transport the medical plastic barrel 18 at the set running speed v. After the medical plastic barrel 18 is transported for L1 stroke, it arrives at the first extrusion assembly. The fixed plate 6 and the movable plate 10 of the first extrusion assembly monitor the extrusion load in real time through the pressure sensor 1 and the pressure sensor 2. The fixed plate 6 and the movable plate 10 of the first extrusion assembly are both at the lowest height, that is, the lower surface of the two plates are flush with the upper surface of the conveyor belt 3, so as to achieve the lower area of ​​the medical plastic barrel 18. Extrusion; the rotary motor 15 drives the movable disk 10 to continuously approach the fixed disk 6 until the resultant force fed back by the pressure sensor 1 and the pressure sensor 2 reaches F1 (the maximum pressure that the medical plastic barrel 18 can withstand) and then stops. The medical plastic barrel 18 slides out from between the two disks and continues to be transported for the distance L2. At this time, the conveyor belt 3 stops running, and the barrel mouth position of the medical plastic barrel 18 is located by the camera 19. After setting the distances L1 and L2, the coordinates of the barrel mouth of the medical plastic barrel 18 should be (x, y), and the barrel mouth coordinates located by the camera 19 are (x1, y1).

[0054] When x1=x and y1=y, it indicates that the medical plastic barrel 18 is precisely located at its preset position coordinates and does not move.

[0055] When x1≠x and y1=y, it indicates that the medical plastic barrel 18 has undergone lateral extrusion deformation. At this time, the conveyor belt 3 is started to continue transporting the medical plastic barrel 18 for a stroke 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 that actually drives the second extrusion assembly 16 drives the fixed plate 6 and the movable plate 10 of the second extrusion assembly 16 to a height located at the upper part of the medical plastic barrel 18 and extrudes. After extrusion, the barrel mouth coordinates after the accumulated L3 stroke are (x2, y2). If x2=x at this time, it indicates that the medical plastic barrel 18 has recovered its deformation after the second extrusion, has good elasticity, and passes the preliminary compression test; if x2≠x, it indicates that the medical plastic barrel 18 cannot be recovered after the second extrusion, and it is marked as unqualified for compression performance and directly rejected.

[0056] When x1=x, y1≠y, it indicates that the medical plastic barrel 18 has undergone longitudinal extrusion deformation. At this time, the conveyor belt 3 is stopped, and the drive motor 1 is controlled according to the coordinates (x1, y1) so that the pneumatic joint 23 is precisely positioned above the barrel mouth through the transverse slide rail 20 and the longitudinal slide rail 21. The second cylinder 22 drives the pneumatic joint 23 to extend so that it is inserted into the medical plastic barrel 18. Then, the air pump 24 is turned on to inflate the medical plastic barrel 18. The inflation rate is controlled to v1 through the flow valve 241 until the pressure sensor 3 242 feedback reaches the designed maximum pressure value of the medical plastic barrel 18. If the pressure value inside the medical plastic barrel 18 cannot be reached, it indicates that the longitudinal deformation of the medical plastic barrel 18 cannot be restored, and it is marked as unqualified for pressure resistance and directly discarded.

[0057] If the internal pressure of the medical plastic barrel 18 reaches the maximum pressure value that meets the requirements of the product itself, the conveyor belt 3 is started to run the L2 stroke, and the medical plastic barrel 18 is transported to the second extrusion assembly 16 for a second extrusion at the same height as the first extrusion. The camera 19 is used to observe whether there is a deviation between the coordinates at the barrel mouth and (x1, y1). If there is a deviation, it indicates that the quality of the medical plastic barrel 18 is poor and cannot withstand multiple extrusions. If there is no deviation, it indicates that there is a weak area in the medical plastic barrel 18. The defect position is recorded by the PLC control system and marked as a processing defect. The preliminary pressure resistance test is qualified.

[0058] When x1≠x and y1≠y, it indicates that the medical plastic barrel 18 is severely squeezed and deformed. In this case, it is directly marked as unqualified in compression resistance and is directly discarded.

[0059] Through the above embodiment, the medical plastic barrel is divided into sections for compression resistance and deformation testing, which realizes multi-dimensional accurate judgment of the horizontal, vertical and severe deformation of the barrel body, and realizes closed-loop control of the entire process from deformation detection, performance judgment, and defect tracing, thereby significantly improving the accuracy, compliance and industrial adaptability of the compression resistance performance testing of the medical plastic barrel 18.

[0060] Embodiment 2:

[0061] In this embodiment, the medical plastic barrel 18 that has passed the preliminary pressure resistance test is subjected to a sealing test, thereby improving the overall quality of the medical plastic barrel 18 .

[0062] Specifically, the medical plastic barrel 18 that has undergone a preliminary pressure resistance test is transported to the end of the L3 stroke via the conveyor belt 3. The pneumatic connector 23 is precisely inserted into the barrel mouth to form a sealed space with the medical plastic barrel 18. The air pump 24 is started to introduce gas into the medical plastic barrel 18 at a constant flow rate, and the gas flow rate is fed back through the flow valve 241. The gas pressure inside the medical plastic barrel 18 is fed back through the pressure sensor 3 242. After the flow valve 241 feeds back that the maximum amount of gas that the medical plastic barrel 18 can carry has been input, the input is stopped. Under normal circumstances, the internal air pressure of the medical plastic barrel 18 after being filled with air is P, and the internal air pressure fed back by the pressure sensor 3 242 is P1. At the same time, the pneumatic connector 23 is synchronously displaced with the medical plastic barrel 18 through the conveyor belt 3 through the longitudinal slide rail 21, so that the medical plastic barrel 18 is inflated while the second extrusion assembly 16 performs a secondary extrusion operation (extruding the upper area of ​​the medical plastic barrel 18);

[0063] When P1=P, it indicates that the internal air pressure of the medical plastic barrel 18 is normal, the plastic barrel is not deformed, and the sealing performance is good; when P1<P and P1 is constant, it indicates that the medical plastic barrel 18 has a slight deformation after the preliminary pressure resistance test, which is not captured by the camera 19 and is marked as a processing defect; when P1<P and P1 is not constant, it indicates that the medical plastic barrel 18 has cracked after the preliminary pressure resistance test. At this time, it will be marked as unqualified for pressure resistance and directly discarded.

[0064] Through the above embodiment, the air tightness and pressure resistance of the medical plastic barrel 18 during internal filling are tested, and hidden defects that are missed in the pressure resistance test are effectively identified. The closed-loop control of the entire process of inflation, extrusion, judgment, and tracing is achieved, which significantly improves the detection accuracy of the sealing performance and structural reliability of the medical plastic barrel, ensuring that the product meets the strict standards of medical packaging.

[0065] Embodiment 3;

[0066] In this embodiment, in order to meet medical grade standards, medical supplies must be sterilized at high temperature, so the medical plastic barrel 18 is heated to test the high temperature resistance of the medical plastic barrel 18 .

[0067] After the medical plastic barrel 18 and the pneumatic joint 23 that have passed the secondary pressure resistance and airtightness test pass through the stroke L4 synchronously, the barrel body falls into the range of the splint 27. At this time, the barrel mouth is exposed outside the baffle 25 through the expansion groove 251. At this time, the second drive motor controls the screw 29 to rotate, so that the splints 27 are displaced toward each other and clamp the medical plastic barrel 18. After clamping, the pneumatic joint 23 is driven to loosen, and the second cylinder 22 drives the contraction to pull the pneumatic joint 23 out of the barrel mouth. After pulling out, the heating wire inside the splint 27 begins to heat up. The heating time is set to t. After t time, the temperature of the medical plastic barrel 18 itself reaches the temperature required for high-temperature disinfection of medical supplies. At this time, the medical plastic barrel 18 is subjected to the same pressure resistance and airtightness tests.

[0068] Specifically, the pneumatic connector 23 is re-inserted and air is introduced into the medical plastic barrel 18. The pressure relief valve 243 opens to prevent thermal expansion from causing the barrel to rupture. The barrel is then transported back to the second extrusion assembly 16 via the conveyor belt 3. The electromagnetic clutch of the rotary motor 15 is de-energized, disengaging the two discs of the medical plastic barrel 18. The displacement sensor reads the displacement of the rack 14, providing feedback on whether thermal expansion has occurred in the lower area. The first cylinder 5 is then driven to raise the second extrusion assembly 16, providing feedback on whether thermal expansion has occurred in the upper area. If so, the medical plastic barrel 18 has poor high-temperature resistance and is discarded. If not, the medical plastic barrel 18 has acceptable high-temperature resistance and has passed the performance test.

[0069] 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 at a constant temperature by 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.
