Description

Technical Field

[0001] This invention relates to a particle detection platform for COP materials, belonging to the field of new material detection technology. Background Technology

[0002] COP (cyclic olefin polymer) is a high-performance material produced by ring-opening metathesis polymerization or metallocene-catalyzed addition polymerization of cyclic olefin monomers. It has high light transmittance and excellent dimensional stability, and is widely used in optical lenses, pharmaceutical packaging, and electronic devices. Cycloolefins are alicyclic hydrocarbons containing carbon-carbon double bonds in their molecules. They have fewer hydrogen atoms than the corresponding cycloalkanes and are classified into monocyclic, bicyclic, bridged, and fused cyclic types. Their properties are similar to those of chain olefins, and they readily undergo electrophilic addition, oxidation, and polymerization reactions. Industrially, they can be obtained from petroleum and animal and plant tissues. In the laboratory, they are prepared through methods such as cycloalcohol elimination and photocyclization dehydrogenation. To ensure the quality of COP particles during production and use, it is necessary to test the mechanical properties and light transmittance of the COP particles.

[0003] Existing COP particles require first testing their mechanical properties using a pressure testing device, and then testing their transmittance using a transmittance meter. This testing method requires two devices, and the same COP particle needs to go through two testing steps, which has the disadvantages of complex testing process, low testing efficiency, and high testing cost.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-13 The present invention provides a technical solution:

[0037] A COP material particle testing platform includes a main support component. This component provides fundamental support and protection for the testing platform, ensuring stable load-bearing and dust protection. The main support component includes a platform 1, with a box-shaped base 2 fixed to its underside. The box-shaped base 2 not only provides a stable support foundation for the platform 1, but its hollow internal structure can also accommodate related circuit components, drive devices, or auxiliary equipment of the testing platform. Several feet are fixed to the underside of the box-shaped base 2. A dust cover 3 is fixed to the upper side of the platform 1. The dust cover 3 effectively protects the components placed on the platform 1 from external dust and impurities entering the testing area, preventing dust and impurities from entering. To improve testing accuracy, an observation hole is provided on one side of the dust cover 3, with a transparent plate fixed inside the observation hole. A dust door is rotatably mounted on one side of the dust cover 3. The dust door and the dust cover 3 are detachably connected via magnetic snap-fit. During testing, the operator can observe the situation on the platform 1 in real time through the transparent plate without opening the dust cover 3. When it is necessary to place COP particles into the dust cover 3, the operator can use external force to overcome the magnetic snap-fit's attraction and rotate the dust door outward to open it. After the operation is completed, the dust door is closed, and the magnetic snap-fit ​​automatically engages under magnetic force, ensuring the airtightness of the dust cover 3.

[0038] To perform pressure testing on COP particles, such as Figures 1-6 , Figure 12 As shown, the main support assembly includes a pressure testing component, which comprises a pressure sensor 4 and a vertical guide rail 5. Both the pressure sensor 4 and the vertical guide rail 5 are fixed to the upper side of the platform 1. A lifting plate 6 slides within the vertical guide rail 5. A guide rod 7 and a pressure frame 8 are fixed to the lower side of the lifting plate 6. The pressure frame 8 has a U-shaped structure, and the guide rod 7 has a T-shaped structure. The pressure frame 8 is located directly above the pressure sensor 4. A mounting bracket is fixed to the upper side of the platform 1, and an electric telescopic rod 9 is fixed on the mounting bracket. A receiving hole is provided on the upper side of the platform 1, and the electric telescopic rod 9 is located within the receiving hole. The shaft end of the electric telescopic rod 9 is fixed... On the lower side of the guide rod 7 and the upper side of the dust cover 3, the control unit 10 is fixed. The upper side of the dust cover 3 is provided with a wiring hole. The control unit 10 is connected to an external power supply through a wire. The electric telescopic rod 9 and the pressure sensor 4 are electrically connected to the control unit 10 through wires to realize signal interaction. When the pressure test is performed, the control unit 10 sends a start signal to the electric telescopic rod 9. The electric telescopic rod 9 retracts and drives the guide rod 7. The guide rod 7 drives the lifting plate 6 to slide vertically downward along the vertical guide rail 5. The vertical guide rail 5 limits the offset of the lifting plate 6 to ensure the accuracy of the pressure direction. The lifting plate 6 synchronously drives the U-shaped pressure frame 8 to move.

[0039] A force plate and a force frame 11 are fixed to the upper side of the pressure sensor 4. When the upper optical transparent part 12 on the lower pressure frame 8 contacts the COP particles on the lower optical transparent part 15 directly above the pressure sensor 4, downward pressure is continuously applied. The pressure is transmitted to the pressure sensor 4 through the COP particles, the force frame 11, and the force plate. The pressure sensor 4 collects pressure data in real time and converts it into an electrical signal, which is transmitted to the control unit 10 through a wire. The control unit 10 processes and displays the data in real time. When the pressure reaches the preset value, the control unit 10 controls the electric telescopic rod 9 to stop. If pressure needs to be maintained, the current state is maintained until the preset time.

[0040] After the pressure holding period, the control unit 10 controls the extension of the electric telescopic rod 9, which drives the guide rod 7, the lifting plate 6, and the lower pressure frame 8 to reset along the vertical guide rail 5. The pressure sensor 4 stops data acquisition and uploads the final test data to the control unit 10. The control unit 10 completes data storage, analysis, and test report generation. Throughout the process, the cooperation between the vertical guide rail 5 and the lifting plate 6 ensures the stability of the pressure application, and the pressure sensor 4 ensures the accuracy of the data. The control unit 10 realizes automated control and data management, and can perform pressure tests on COP particles through the pressure test components.

[0041] To perform deformation detection on COP particles, such as Figure 6 As shown, the fork-shaped frame 20 has a through hole, and a distance sensor 22 is fixed inside the through hole. The distance sensor 22 is located below the lower pressure frame 8. The distance sensor 22 is electrically connected to the control unit 10 through a wire. When the pressure test is performed, after the upper optical transparent part 12 contacts the COP particle, the distance between the distance sensor 22 and the lower pressure frame 8 can be recorded by the distance sensor 22. Then the upper optical transparent part 12 continues to descend, which can apply pressure to the COP particle. At this time, the pressure measured by the pressure sensor 4, combined with the distance the lower pressure frame 8 moves measured by the distance sensor 22, can be used to know the deformation of the COP particle, so that the deformation of the COP particle can be detected.

[0042] To perform transmittance testing on COP particles, such as Figures 1-6As shown, the main support assembly includes a light transmission testing component, which comprises an upper optically transparent element 12. A stepped hole is provided on the lower side of the lower pressure frame 8, and the upper optically transparent element 12 is fixed inside the stepped hole. A spotlight 13 is fixed on the upper side of the upper optically transparent element 12, and a photosensitive sensor 14 is fixed on the upper side of the force plate. The spotlight 13 is located directly above the photosensitive sensor 14. The spotlight 13 and the photosensitive sensor 14 are electrically connected to the control unit 10 via wires. A light-transmitting hole is provided on the upper side of the force plate 11, and a lower optically transparent element 15 is fixed inside the light-transmitting hole, located directly above the photosensitive sensor 14. During pressure testing, the light transmission testing component can be controlled via the control unit 10. The integrated machine 10 controls the spotlight 13 to turn on. The light emitted by the spotlight 13 passes through the upper optical transparent part 12 and shines on the COP particles. After passing through the COP particles, the light passes through the lower optical transparent part 15 in the light-transmitting hole of the force support frame 11 and is received by the photosensitive sensor 14 on the upper side of the force support plate. The photosensitive sensor 14 converts the received light signal into an electrical signal and transmits it to the control integrated machine 10. The control integrated machine 10 calculates the light transmittance of the COP particles based on the difference between the initial light intensity of the spotlight 13 and the light intensity received by the photosensitive sensor 14, and then performs a light transmittance test. The pressure test component and the light transmittance test component work together to achieve simultaneous pressure test and light transmittance test.

[0043] Furthermore, during the pressure application process, if the pressure reaches the preset threshold or the light transmittance changes abnormally, the control unit 10 can automatically control the electric telescopic rod 9 to stop, preventing the COP particles from being damaged by excessive pressure, and at the same time recording the current data.

[0044] To ensure the accuracy of the light transmittance test, a light-shielding assembly is provided above the lower optical transparent component 15. The light-shielding assembly includes a horizontal plate 16, with two uprights fixed to the lower side of the horizontal plate 16. The uprights are fixed to the upper side of the table panel 1. A T-shaped hole is provided on the lower side of the horizontal plate 16, and the upper part of the lower optical transparent component 15 is located within the T-shaped hole. The lower optical transparent component 15 does not contact the horizontal plate 16. A flexible light-shielding corrugated telescopic ring 17 and a gasket are fixed to the upper side of the horizontal plate 16. A pressure plate 18 is provided above the flexible light-shielding corrugated telescopic ring 17, and a through hole is provided on the lower side of the pressure plate 18. The through hole, the flexible light-shielding corrugated telescopic ring 17, and the T-shaped hole are coaxially arranged. During testing, when the pressure plate 18 is pressed down, it flattens the flexible light-blocking corrugated expansion ring 17. At this time, the inner ring of the flexible light-blocking corrugated expansion ring 17 shrinks and fits into the COP particles. Because the flexible light-blocking corrugated expansion ring 17 has extensibility and contraction, and is made of flexible and elastic material, it can automatically shrink and reset when the pressure is released. Then, the light transmittance test is performed. At this time, light can only pass through the COP particles and shine on the photosensitive sensor 14. The light outside the COP particles is blocked by the flexible light-blocking corrugated expansion ring 17, thus enabling accurate light transmittance testing of the COP particles.

[0045] In order to enable the pressure plate 18 to automatically press down and reset, such as Figure 3 , Figure 6 As shown, two connecting brackets are fixed to the lower side of the pressure plate 18. The connecting brackets are L-shaped. Two guide holes are provided on the upper side of the horizontal plate 16. The connecting brackets slide inside the guide holes. A first spring 19 is fixed to the lower side of the connecting brackets. The lower end of the first spring 19 is fixed to the upright. Two light-shielding plates are fixed to the upper side of the force plate. The photosensitive sensor 14 is located between the two light-shielding plates, which can further block external light interference and ensure the stability of the light transmission test environment. A wire hole is provided on one side of one light-shielding plate. A fork-shaped bracket slides on the outer periphery of the guide rod 7. 20. The lower side of the fork-shaped frame 20 contacts the upper bottom of the guide rod 7. The fork-shaped frame 20 slides within the vertical guide rail 5. A second spring 21 is fixed between the upper side of the fork-shaped frame 20 and the lower side of the lower pressure frame 8. The tension of the second spring 21 is greater than the tension of the first spring 19, and the tension of the second spring 21 is much greater than the sum of the tensions of the two first springs 19. The fork-shaped frame 20 is located above the pressure plate 18 and can contact the pressure plate 18. During the pressure test, the lifting plate 6 and the fork-shaped frame 20 will descend first. When the fork-shaped frame 20 moves to contact the pressure plate 18, it will continue to push the pressure plate 18 to move. The connecting frame slides along the two guide holes on the upper side of the horizontal plate 16. At this time, the first spring 19 is compressed, and the flexible light-shielding corrugated telescopic ring 17 is also flattened. When the pressure plate 18 contacts the washer ring, the pressure plate 18 will stop moving. Then, the lifting plate 6 and the guide rod 7 will continue to descend for pressure testing. During this period, the second spring 21 will be compressed. When the pressure test is completed and the lifting plate 6 and the guide rod 7 move upward, the second spring 21 will release first. As the fork-shaped frame 20 extends, when its lower side contacts the upper bottom of the guide rod 7, the fork-shaped frame 20 will also move upward along with the lifting plate 6 and the guide rod 7. Then, the pressure plate 18 will automatically rise and reset due to the tension of the first spring 19. Then, the flexible light-shielding corrugated telescopic ring 17 will also automatically retract and reset. The inner ring of the flexible light-shielding corrugated telescopic ring 17 will become larger and separate from the COP particles. It can achieve accurate light transmittance testing while performing pressure testing on the COP particles by cooperating with the pressure testing component and the light transmittance testing component.

[0046] For precise automatic material changing, such as Figure 3 , Figures 7-10 , Figure 12 , Figure 13As shown, a material changing component is provided on one side of the pressure testing assembly. The material changing component includes a translation frame 23 and a three-way connector. A positioning table 32 is fixed on the upper side of the platform 1. The upper side of the positioning table 32 has a positioning groove. Before changing the material, the COP particles to be tested need to be placed in the positioning groove in advance to facilitate subsequent material removal. This placement can be done during the testing process to improve testing efficiency. The translation frame 23 slides on the upper side of the platform 1. A driving block is fixed on the lower side of the translation frame 23. An elongated hole is provided on the upper side of the platform 1, and the driving block slides inside the elongated hole. An execution component for driving the driving block to move is provided on the lower side of the platform 1. The execution component includes a stepper motor. The stepper motor 31 is electrically connected to the control unit 10 via wires. A threaded rod is fixed to the shaft end of the stepper motor 31. The threaded rod is rotatably connected to the lower side of the platform 1. A threaded hole is provided on one side of the drive block. The threaded rod is connected to the inner side of the threaded hole through threaded transmission. When one COP particle needs to be replaced after testing, the stepper motor 31 in the execution component can be started to rotate through the control unit 10. The shaft end of the stepper motor 31 drives the threaded rod to rotate. The threaded rod drives the drive block to move through threaded transmission. The drive block drives the translation frame 23 to move, so that the lifting frame 24 moves to the corresponding position of the COP particle to be picked up.

[0047] To accurately pick up COP particles, a lifting frame 24 slides on one side of the translation frame 23. A second electric push rod 25 is fixed to one side of the translation frame 23, with its shaft end fixed to the lifting frame 24. The second electric push rod 25 is electrically connected to the control unit 10 via a wire. The upper side of the lifting frame 24 is provided with a suction hole and a suction hole. A suction nozzle 26 is fixed inside the suction hole, a ramp flexible ring is fixed inside the suction nozzle 26, and a barrier net is fixed inside the ramp flexible ring. A suction nozzle 27 is fixed inside the suction hole, and a washer is fixed to the lower side of the suction nozzle 27. Both the suction nozzle 26 and the suction nozzle 27 have bent pipes fixedly connected to their outer circumferences. The bent pipes are fixed to the lifting frame 24 and are fixedly connected to a tee connector. When changing materials, the suction nozzle 26 must first be moved above the positioning platform 32 and aligned with the COP particles. Then, the second electric push rod 25 is controlled to extend, causing the lifting frame 24 to lift the COP particles. As the lowering frame 24 descends, the inclined flexible ring comes into contact with the COP particles. The inclined flexible ring adheres to the surface of the COP particles to form a seal, and the suction nozzle 27 covers the COP particles that have already been tested. This creates suction within the bend, allowing the particles to be sucked up through the suction nozzle 26. The barrier net inside the inclined flexible ring prevents particles from entering the pipeline. Simultaneously, the suction nozzle 27 can remove the tested COP particles and also remove dust and impurities from the lower optical transparent component 15, achieving automatic cleaning. Then, the translation frame 23 moves horizontally in conjunction with the lifting frame 24 to move up or down, moving the COP particles to be tested above the lower optical transparent component 15. This stops the suction within the bend, and the COP particles fall above the lower optical transparent component 15, completing the material change. After the material change is completed, the lifting frame 24 needs to be moved aside to avoid affecting the testing of the COP particles.

[0048] To create suction inside the bend, such as Figure 10 , Figure 11As shown, one end of the three-way connector is fixedly connected to a flexible hose 28. One end of the flexible hose 28 is equipped with a suction filter assembly, which includes an air extractor. The air extractor is electrically connected to the control unit 10 via a wire. The exhaust port of the air extractor is fixedly connected to a return air pipe. Two pipe holes are provided on one side of the dust cover 3, with the return air pipe and flexible hose 28 respectively fixed inside the pipe holes. A filter cartridge 29 is fixed to the outer wall of the dust cover 3. The air intake port of the air extractor is fixedly connected to a suction pipe. Ventilation holes are provided on both sides of the filter cartridge 29, with the suction pipe and flexible hose 28 respectively fixed inside the ventilation holes. A filter screen is detachable from the inner side of the filter cartridge 29. A drop hole is provided at the bottom of the filter cartridge 29, with a drop pipe fixed inside the drop hole. A collection cover 30 is detachably attached to the outer circumference of the drop pipe via a sleeve connection. The collection cover 30 is detachably connected to the outer wall of the drop pipe. A sealing device is fixed inside the collection cover 30. The sealing ring is attached to the outer wall of the drop tube via a sleeve. When suction is required in the bend, the integrated machine 10 is operated to start the suction machine. The suction machine draws air from the filter cartridge 29 through the suction pipe. The filter cartridge 29 generates suction in the two bends through the hose 28 and the three-way connector. When the suction in the bends needs to be stopped, the suction machine is simply stopped. During material change, the COP particles and dust sucked by the suction nozzle 27 will enter the filter cartridge 29 through the bend, the three-way connector, and the hose 28, and then be blocked by the filter screen. When the suction machine stops, the COP particles will fall into the collection cover 30. When the collection cover 30 needs to be cleaned, it can be removed to clean the COP particles inside. The material change component can replace the COP particles and clean the light transmittance test component at the same time.

[0049] The workflow of this embodiment is as follows: When COP particle detection is required, the control unit 10 initializes, the material changing component drives the translation frame 23 to move via the stepper motor 31, the second electric push rod 25 drives the lifting frame 24 to rise and fall, and the suction nozzle 26 picks up COP particles from the positioning table 32 and places them on the lower optically transparent part 15 of the force-bearing frame 11. Then the pressure test begins, the electric telescopic rod 9 drives the guide rod 7 to make the lifting plate 6 descend along the vertical guide rail 5, the lower pressure frame 8 applies pressure, the pressure sensor 4 transmits data to the control unit 10, and at the same time the distance sensor 22 monitors the distance and performs deformation testing. In the light transmission test, when the lifting plate 6 descends, the fork frame 20 pushes the pressure plate 18 to form a light-blocking effect, the spotlight 13 emits light, and the photosensitive sensor 14 receives and transmits the light data. After the test, the lifting plate 6 is raised, the suction nozzle 27 of the material changing component removes the COP particles and cleans the light transmission test component. At the same time, the COP particles to be tested on the positioning table 32 are transferred to the lower optical transparent part 15 through the suction nozzle 26. The COP particles and impurities are filtered by the filter cartridge 29 and collected by the collection cover 30. The control integrated machine 10 records and analyzes the data to generate a report, completing one test. Continuous testing can be performed for continuous operation.
