Description

Technical Field

[0001] This invention relates to the field of viscosity testing equipment, and in particular to a viscosity testing device for the production of high-temperature resistant resin adhesives used for fixing conductive structures. Background Technology

[0002] In the production process of high-temperature resistant resin adhesive used for fixing conductive structures, the curing agent and accelerator need to be added to the reaction vessel in a preset ratio, stirred to generate raw materials, and the viscosity change of the raw materials is monitored in real time to ensure the stability of the product's conductivity and bonding strength.

[0003] A lubricating oil viscosity testing device disclosed in patent application CN121090339A includes a base to which a barrel is fixedly connected. It further includes a stirring viscosity measuring mechanism connected to the base, comprising a lifting adjustment mechanism connected to a telescopic rotation mechanism. A protective shell is fixedly installed at the end of the telescopic rotation mechanism, and a first motor is fixedly installed inside the protective shell. The output shaft of the first motor is fixedly connected to a rotating disk, which is rotatably connected to the protective shell. A fixed plate is fixedly connected to the rotating disk, and a resistance sensor is fixedly connected to the fixed plate. A scraper is fixedly connected to the lower end of the fixed plate. An oil removal mechanism is also connected to the lifting adjustment mechanism. This invention measures lubricating oil viscosity through the cooperation of the stirring viscosity measuring mechanism and the oil removal mechanism, followed by an automated oil-removing spray and brushing operation, thus achieving automatic measurement and cleaning, and improving testing efficiency.

[0004] The following problems exist during use: Air bubbles in the sample interfere with detection accuracy: 1. Air bubbles are easily introduced during sample transport or transfer. Existing defoaming methods are relatively simple, mostly using static placement or single-stage filtration, with limited effect on bubble elimination, especially difficult to remove deep, micro-bubbles. Residual air bubbles significantly interfere with viscosity detection results, causing data errors and reducing the accuracy and reliability of the detection; 2. Secondary air bubbles are easily generated when the sample is poured into the detection container: Existing equipment, during the process of pouring the sample into the placement cylinder, lacks a smooth guiding and buffering structure, and the liquid impact easily generates new air bubbles, further increasing the gas content in the sample and affecting the stability of subsequent detection; 3. The stirring mechanism introduces additional disturbance: Although some equipment is equipped with a stirring mechanism to assist in defoaming, the lack of precise magnetic control and automatic reset design during the insertion and removal of the stirring plate from the sample easily causes additional disturbance to the sample or introduces air bubbles, affecting the repeatability and consistency of the detection.

[0005] Therefore, it is necessary to provide viscosity testing equipment for the production of high-temperature resistant resin adhesives used for fixing conductive structures to solve the above-mentioned technical problems. Summary of the Invention

The bottom of the guide cylinder is fixedly connected to a receiving seat, and the top of the receiving seat is fixedly connected to an air bladder. The air bladder is connected to an external air supply pipe. When guiding liquid, the air bladder inflates and expands, and when guiding stops, the air bladder contracts.

[0013] As a further aspect of the present invention: a second filter disc is rotatably connected to the bottom of the inside of the guide cylinder, and multiple brush rods are fixedly connected to the outside of the second filter disc. An air extraction cylinder is fixedly connected to the top of the inside of the guide cylinder, and an air pump is connected to the outside of the air extraction cylinder through an air suction pipe to absorb the gas in the liquid below the second filter disc.

[0015] As a further aspect of the present invention: a limiting frame is fixedly connected inside the placement cylinder, and a stirring plate is provided inside the limiting frame. The stirring plate passes through the bottom end of the limiting frame and is slidably connected to the limiting frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution uses multiple placement cylinders to receive samples. Through automatic switching and detection of multiple placement cylinders, there is no need for frequent manual sample replacement.

[0019] 3. The gas in the bubbles is extracted using a vacuum pump, and the multiple brushes on the outside of the second filter plate also help eliminate bubbles during contact with the sample. This design avoids the problem of bubble generation when the sample is directly poured into the placement cylinder in existing technologies, ensuring that the sample entering the placement cylinder has an extremely low gas content, thereby significantly improving the accuracy and stability of subsequent viscosity detection.

[0020] 4. After the electromagnet is completely separated from the placement cylinder, it automatically resets under the action of the second elastic element. This design achieves multi-stage, dynamic defoaming of the sample before testing, and avoids additional disturbance to the sample by magnetically controlling the insertion and removal of the stirring plate. At the same time, centrifugation can effectively eliminate deep micro-bubbles, further ensuring the accuracy and repeatability of viscosity testing. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] like Figures 1 to 10 As shown, a viscosity testing device for producing high-temperature resistant resin adhesives for fixing conductive structures includes the following embodiments: Example 1: Includes a testing station 1, and also includes: Rotary stage 201 is fixedly connected to the top of detection stage 1, and the output shaft of rotary stage 201 is fixedly connected to rotating disk 2. Multiple placement cylinders 3 for receiving samples are provided on the top of rotating disk 2. Defoaming cylinder 4 is located on top of rotating disk 2. Defoaming cylinder 4 is connected to an external liquid delivery pipeline. Defoaming mechanism is installed inside defoaming cylinder 4. Guide component for guiding liquid is installed at the bottom of defoaming cylinder 4. The limiting frame 5 is fixedly connected to the top of the testing table 1, and an electromagnet 501 is installed inside the limiting frame 5. When the electromagnet 501 is energized, it magnetically attracts the placement cylinder 3. Viscosity meter 6 and cleaning device 7 are both located on the top of rotating disk 2. Lifting components for lifting are provided on the outside of viscosity meter 6, cleaning device 7 and defoaming cylinder 4. The lifting components adopt lifting slide rails, which is existing technology and will not be further described here.

[0027] In practical implementation, during the production process, the curing agent and accelerator are added to the reaction vessel in a preset ratio and stirred to generate raw materials. Real-time monitoring of the viscosity changes of the raw materials is required during production. Therefore, this solution uses an external liquid delivery pipeline to transport the raw materials to the defoaming cylinder 4. The defoaming cylinder 4 defoams the stirred raw materials, effectively removing air bubbles and preventing them from interfering with subsequent viscosity testing, thus significantly improving the reliability and repeatability of the test data. When the sample is injected into the placement cylinder 3, a guide is used to ensure a smooth and controllable injection process, reducing splashing and residue, minimizing sample loss and cross-contamination risks, and preventing air bubbles from being generated during direct transport. This further eliminates detection errors caused by air bubbles and ensures the accuracy of the test results. Simultaneously, this solution uses multiple placement cylinders 3 to receive samples. Automatic switching between multiple placement cylinders 3 eliminates the need for frequent manual sample changes, allowing for periodic testing of raw materials at different times. This enables continuous and automated monitoring of the raw material viscosity at different points in the reaction process, providing real-time insight into the dynamic changes in raw material viscosity. This provides a basis for adjusting the ratio of curing agent and accelerator or stirring parameters, effectively optimizing process control and ensuring product quality stability.

[0028] Heating wires can also be installed on the inner wall of the placement cylinder 3 to ensure temperature control of the sample.

[0029] Example 2: A flow frame 401 is fixedly connected to the outside of the defoaming cylinder 4. Multiple liquid outlets 402 are provided on the outside of the flow frame 401. A delivery pump 400 is connected to the outside of the flow frame 401 through a connecting pipe. A first filter plate 403 is fixedly connected inside the defoaming cylinder 4. A rotating plate 404 is provided below the first filter plate 403. The rotating plate 404 is rotatably connected to the defoaming cylinder 4. Multiple filter plates 409 are fixedly connected inside the rotating plate 404.

[0030] The defoaming mechanism includes a lower pressure plate 405, which is disposed inside the defoaming cylinder 4. An electric push rod 406 is fixedly connected to the top of the defoaming cylinder 4. The telescopic end of the electric push rod 406 passes through the defoaming cylinder 4 and is fixedly connected to the lower pressure plate 405. A fixing rod 407 is fixedly connected to the bottom of the lower pressure plate 405. A spiral groove 408 is opened on the outer side of the fixing rod 407. The fixing rod 407 passes through the first filter disc 403 and the rotating plate 404. The fixing rod 407 is slidably connected to the first filter disc 403. A connecting shaft 4040 is fixedly connected inside the rotating plate 404. The connecting shaft 4040 extends to the spiral groove 408 opened on the outer side of the fixing rod 407. When the fixing rod 407 descends, it drives the rotating plate 404 to rotate through the connecting shaft 4040.

[0031] In practice, during the defoaming process, the delivery pump 400 delivers the raw material to the flow frame 401. The flow frame 401 disperses the raw material into the defoaming cylinder 4 through multiple liquid outlets 402. This dispersion delivery method can initially eliminate bubbles in the sample. Subsequently, the electric push rod 406 is activated, and its telescopic end drives the lower pressure plate 405 to descend. The lower pressure plate 405 presses down to create negative pressure, allowing the sample to pass smoothly through the first filter disc 403 and the filter plate 409. At the same time, the fixing rod 407 fixedly connected to the bottom of the lower pressure plate 405 also descends. When the fixing rod 407 passes through the rotating plate 404, the spiral groove 408 on its outer side squeezes the connecting shaft 4040, thereby driving the rotating plate 404 to rotate. When the rotating plate 404 rotates, the filter plate 409 and the first filter disc 403 rotate relative to each other. The synergistic effect of the two can significantly improve the bubble elimination effect, achieving dual defoaming. This design ensures that the sample is defoamed efficiently before being transported to the placement cylinder 3, effectively avoiding errors caused by residual bubbles in subsequent viscosity testing, and further improving the accuracy and reliability of the test data.

[0032] In this embodiment, a movable ring 410 is provided at the bottom of the rotating plate 404. Multiple cleaning plates 411 are fixedly connected inside the movable ring 410. A brush is provided at the top of the cleaning plate 411, and the cleaning plate 411 covers the bottom of the filter plate 409. A fixed ring 412 is provided at the bottom of the movable ring 410. A limit rod 413 is fixedly connected at the top of the fixed ring 412. Multiple limit rods 413 pass through the movable ring 410 and are slidably connected to the movable ring 410. Springs 414 are sleeved on the outside of multiple limit rods 413.

[0033] Multiple pressure plates 415 are fixedly connected to the bottom of the fixed rod 407. A connecting plate 416 is fixedly connected inside the defoaming cylinder 4. A rotating wheel 419 is provided on one side of each connecting plate 416. A support rod is fixedly connected to one side of the rotating wheel 419. The support rod passes through the connecting plate 416 and is rotatably connected to the connecting plate 416. A torsion spring is fixedly connected between the support rod and the connecting plate 416. A take-up reel 421 is fixedly connected to the other end of the support rod. A pull rope 420 is wound around the outside of the take-up reel 421. One end of the pull rope 420 is fixedly connected to the pressure plate 415. A first pull plate 417 is eccentrically rotatably connected to one side of the rotating wheel 419. A second pull plate 418 is rotatably connected to one end of the first pull plate 417. The second pull plate 418 is fixedly connected to the moving ring 410.

[0034] In specific implementation, this scheme also includes a moving ring 410, inside which a cleaning plate 411 is fixedly connected. The cleaning plate 411 can seal the filter plate 409, so that the sample first gathers at the top of the first filter plate 403 and settles during the injection process. When the pressure plate 405 descends, the negative pressure pushes the sample through the filter structure, thereby increasing the squeezing force and promoting defoaming. At the same time, the fixed rod 407 descends and drives the rotating plate 404 to rotate, forming a misalignment, so that the sample is further defoamed while being filtered. In addition, the pressure plate 415 fixedly connected to the bottom of the fixed rod 407 descends synchronously. Multiple pressure plates 415 pull the winding reel 421 to rotate through the pull rope 420. The winding reel 421 drives the support rod and the rotating wheel 419 to rotate. The rotating wheel 419 pulls the second pull plate 418 to reciprocate up and down through the eccentrically connected first pull plate 417, thereby driving the moving ring 410 to reset and rise and fall. Simultaneously, the limiting rod 413 and the spring 414 work together to assist the cleaning plate 411 in reciprocating upward movement, maintaining contact between the cleaning plate 411 and the filter plate 409. The brushes on the cleaning plate 411 effectively puncture air bubbles during the reciprocating motion and clean residual air bubbles and debris from the filter plate 409. The coordinated operation of these mechanisms significantly improves the overall defoaming effect, ensuring a lower gas content in the sample before testing, thereby further enhancing the accuracy and stability of viscosity detection.

[0035] Example 3: The guide includes a guide frame 801, which is fixedly connected to the bottom of the defoaming cylinder 4. The bottom of the defoaming cylinder 4 has a through groove, and a guide cylinder 8 is fixedly connected to the bottom of the defoaming cylinder 4. The guide frame 801 is sleeved on the outside of the guide cylinder 8, and a filter ring 807 is fixedly connected between the guide frame 801 and the guide cylinder 8. A receiving seat 800 is fixedly connected to the bottom of the guide cylinder 8, and an airbag 802 is fixedly connected to the top of the receiving seat 800. The airbag 802 is connected to an external air supply pipe. When guiding liquid, the airbag 802 inflates and expands, and when guiding stops, the airbag 802 contracts.

[0036] The bottom of the guide tube 8 is rotatably connected to a second filter disc 803, and multiple brush rods 804 are fixedly connected to the outside of the second filter disc 803. The top of the guide tube 8 is fixedly connected to an air extraction cylinder 806, and an air extraction pump 805 is connected to the outside of the air extraction cylinder 806 through an air suction pipe to absorb the gas in the liquid below the second filter disc 803.

[0037] In practice, after the defoamed sample falls to the bottom of the defoaming cylinder 4, it first enters the guide frame 801 and slides down along it. The sample passes through the filter ring 807 between the guide frame 801 and the guide cylinder 8, and continues to slide down the side wall of the guide cylinder 8. This guiding method effectively prevents new bubbles from being generated during the sample feeding process due to impact, and any remaining bubbles are eliminated as the sample slides along the side wall. When the sample falls onto the receiving seat 800 at the bottom of the guide cylinder 8, the air bladder 802 inside the receiving seat 800 inflates, cushioning the sample and allowing it to fall smoothly and steadily into the placement cylinder 3, further suppressing bubble generation. As the liquid level inside the placement cylinder 3 rises, the defoaming cylinder 4 rises synchronously with the guide cylinder 8, and the bubbles above the liquid surface contact the second filter plate 803. At this time, the gas in the bubbles is extracted by the vacuum pump 806, and the multiple brush rods 804 on the outside of the second filter plate 803 also assist in eliminating bubbles during contact with the sample. The above design avoids the problem of air bubbles being generated when the sample is directly poured into the placement cylinder 3 in the prior art, ensuring that the sample entering the placement cylinder 3 has an extremely low gas content, thereby significantly improving the accuracy and stability of subsequent viscosity detection.

[0038] Example 4: A connecting rod 301 is fixedly connected to the bottom of the placement cylinder 3. The connecting rod 301 passes through the rotating disk 2 and is rotatably connected to the rotating disk 2. A first gear 302 is fixedly connected to the outside of the connecting rod 301. The connecting rod 301 is connected to the placement cylinder 3. A control valve 303 is provided at the bottom of the connecting rod 301. A toothed ring 507 is provided at the bottom of the rotating disk 2. The toothed ring 507 is fixedly connected to the bottom of the detection table 1 through a support plate. A portion of the teeth are opened inside the toothed ring 507, and the teeth mesh with the first gear 302.

[0039] A limiting frame 304 is fixedly connected inside the placement cylinder 3. A stirring plate 305 is provided inside the limiting frame 304. The stirring plate 305 passes through the bottom end of the limiting frame 304 and is slidably connected to the limiting frame 304. A first elastic element 306 is fixedly connected between one end of the stirring plate 305 and one end of the limiting frame 304.

[0040] A connecting ring 502 is rotatably connected to the top of the electromagnet 501. A sliding plate 505 is fixedly connected to the outside of the connecting ring 502. A groove is opened on the top of the limiting frame 5. The sliding plate 505 extends into the groove, and a second elastic element 503 is fixedly connected between the sliding plate 505 and the limiting frame 5. A guide plate 506 is fixedly connected to the outside of the connecting ring 502. A sliding resistor 504 is fixedly connected to the top of the limiting frame 5. A sliding resistor 504 is slidably arranged on the outside of the guide plate 506. When the guide plate 506 slides outside the sliding resistor 504, the control current decreases, thereby controlling the magnetism of the guide frame 801. After the electromagnet 501 is energized, it repels the magnetism of the stirring plate 305.

[0041] In practice, when the sample-containing placement cylinder 3 rotates with the rotating disk 2 to below the electromagnet 501, the electromagnet 501 is energized, generating magnetic attraction with the placement cylinder 3. At this time, the multiple stirring plates 305 inside the placement cylinder 3 are subjected to magnetic repulsion, sliding along the limiting frame 304 into the sample and stretching the first elastic element 306. Simultaneously, the first gear 302 at the bottom of the placement cylinder 3 meshes with the gear ring 507, driving the placement cylinder 3 to rotate, causing the defoaming cylinder 4 and the multiple stirring plates 305 inside to rotate as well. Through centrifugal rotation, the sample is moved, further eliminating any remaining bubbles in the sample. As the placement cylinder 3 continues to move, the connecting ring 502 on the electromagnet 501 drives the guide plate 506 to slide on the sliding resistor 504, gradually reducing the current to the electromagnet 501 and weakening its magnetism. At this time, the stirring plates 305 slowly reset under the restoring force of the first elastic element 306, automatically detaching from the sample. After the electromagnet 501 is completely separated from the placement cylinder 3, the electromagnet 501 automatically resets under the action of the second elastic element 503. This design realizes multi-stage, dynamic defoaming of the sample before detection, and avoids additional disturbance to the sample by magnetically controlling the insertion and removal of the stirring plate. At the same time, centrifugation can effectively eliminate deep micro-bubbles, further ensuring the accuracy and repeatability of viscosity detection.
