Description

Technical Field

[0001] The present invention relates to the technical field of rubber sleeve performance detection, and in particular to a detection device and a detection method for evaluating the performance of a waterproof rubber sleeve. Background Art

[0002] In many industrial scenarios, such as waterproof sealing in automobile engine compartments, protection of deep-sea diving equipment, and packaging of outdoor electronic equipment, waterproof rubber sleeves play a vital role, and their performance is directly related to the safety and reliability of the equipment.

[0003] However, during the manufacturing process of waterproof rubber sleeves, affected by factors such as raw material quality and processing technology accuracy, defects such as bubbles, cracks, and delamination are prone to occur inside the sleeves. These defects may not be obvious in the initial use of the sleeves, but with the passage of time and the influence of external environmental factors (such as temperature changes, mechanical stress, chemical corrosion, etc.), they will gradually expand, eventually leading to a decrease in waterproof performance and causing equipment failure.

[0004] Traditional methods for testing waterproof rubber sleeves mostly rely on appearance inspections and single physical performance tests. Appearance inspections can only reveal more obvious flaws on the surface of the rubber sleeves, but are powerless against hidden defects inside. Physical performance tests can only perform single tests on waterproof rubber sleeves, such as tensile strength tests and hardness tests. Although they can evaluate the overall performance of the rubber sleeves to a certain extent, they cannot comprehensively evaluate the overall and comprehensive performance of the waterproof rubber sleeves, and thus cannot accurately locate the position and characteristics of internal defects. This type of testing is particularly limited when faced with some application scenarios with extremely high waterproof requirements. For example, in the aerospace field, once a waterproof rubber sleeve fails, it may cause serious safety accidents. Summary of the invention

The end of the discharge pipe 11 extends to the interior of the storage box 13.

[0052] Strong magnets are fixedly connected to opposite sides of the two clamping plates 503 , and the magnetic properties of the two strong magnets are opposite.

[0053] In this embodiment, when the performance of the waterproof rubber sleeve is tested, the vibration motor 104 is first started. When the vibration motor 104 is running, it drives the discharge channel 105 to vibrate, and then the waterproof rubber sleeve in the collection barrel 101 is placed on the vibration plate 102 in sequence, and then the waterproof rubber sleeve is sent one by one to the placement plate 404 on the dividing plate 203 through vibration. When the waterproof rubber sleeve is placed on the dividing plate 203, the motor 202 is started at this time. When the motor 202 is running, it drives the dividing plate 203 to rotate. When the dividing plate 203 rotates, it drives the placement plate 404 thereon to rotate, and the placement plate 404 is rotated to the bottom of the mounting plate 5;

[0054] When the placement plate 404 is placed under the mounting plate 5, the first drive motor 301 is started. When the first drive motor 301 is running, it drives the connecting screw 302 to rotate. When the connecting screw 302 rotates, it drives its moving block 303 to move downward through the thread action. When the moving block 303 moves downward, it drives the connecting block 304, the connecting piece 306 and the connecting rod 307 to move downward. When the connecting rod 307 moves downward, it drives the pressing plate 402 to squeeze the waterproof rubber sleeve on the placement plate 404 downward through the pressure hole, thereby applying pressure to the waterproof rubber sleeve. At this time, the pressure sensor 405 at the bottom of the waterproof rubber sleeve detects the pressure applied to the waterproof rubber sleeve, and the displacement sensor 406 detects the compression of the waterproof rubber sleeve, so that the measured tension and elongation of the waterproof rubber sleeve can be measured and recorded. The maximum tension and the final elongation are recorded, and then the pressure sensor 405 and the displacement sensor 406 convert the measured signals into electrical signals and convert them into image signals through the control processor and transmit them to the control display 8, so that the mechanical properties of the waterproof rubber sleeve under the compression load can be analyzed; then, the second driving motor 401 is driven to rotate the pressure plate 401, and the rotation of the pressure plate 401 drives the waterproof rubber sleeve to rotate, so that when the waterproof rubber sleeve rotates, a torque can be applied to the waterproof rubber sleeve, and at this time, the torque applied to the waterproof rubber sleeve is detected by the torque sensor 4, and the angle sensor 403 detects its torsion angle, and records the maximum torque and the final torsion angle, so that the anti-torsion performance of the waterproof rubber sleeve can be evaluated, and its torsion strength, torsion modulus and other parameters can be determined.

[0055] Specifically, after the torsional performance test of the waterproof rubber sleeve is completed, the waterproof rubber sleeve is clamped by the clamping plate 503, and then the electric compression rods 501 on both sides of the pressure plate 503 are started. When the electric compression rods 501 are running, they drive the driving rod 502 to move in the opposite direction. When the driving rod 502 moves, it drives the two clamping plates 503 to move to both sides. When the two clamping plates 503 move, the waterproof rubber sleeve in the middle is stretched. At this time, the pressure sensor 2 504 is used to detect the magnitude of the tension applied to both sides of the waterproof rubber sleeve, and the displacement sensor 2 505 detects its elongation, and records its maximum tension and final elongation, so as to determine the tensile strength and yield strength mechanical indicators of the waterproof rubber sleeve.

[0056] Furthermore, after the tensile strength and yield strength performance tests of the waterproof rubber sleeve are completed, the motor 202 is started again to drive the indexing plate 203 to rotate to one side of the fixed concave plate 6. At this time, a suitable coupling agent is applied to the ultrasonic probe 603 and it is tightly fitted on the surface of the waterproof rubber sleeve. Then the electric push rod 601 is started, and the electric push rod 601 drives the ultrasonic generator 602 to move. Then the ultrasonic generator 602 is started. When the ultrasonic generator 602 is running, it generates a high-frequency electrical signal. At this time, the ultrasonic generator 602 transmits the generated electrical signal to the ultrasonic probe 603. When the ultrasonic generator 602 moves, it drives the ultrasonic probe 603 to move and gradually covers the detection area on the surface of the waterproof rubber sleeve. The ultrasonic probe 603 converts the electrical signal into an ultrasonic wave and transmits it to the inside of the waterproof rubber sleeve. When ultrasonic waves propagate in a uniform medium, they will be reflected and refracted when encountering interfaces of different media. Therefore, when defects (such as bubbles, cracks, etc.) occur inside the waterproof rubber sleeve, ultrasonic waves will generate reflected waves at the defective interfaces. The reflected waves are then reflected and received and amplified by the signal amplifier 604. The signal amplifier 604 then transmits the amplified signal to the signal processor 605. The signal processor 605 analyzes and processes the amplified signal. The signal processor 605 then transmits the processed signal to the control display 8. The control display 8 displays the processed signal results, thereby determining the location, size or nature of the defects inside the waterproof rubber sleeve, and recording the location and characteristics of the abnormal reflected signal, and marking possible defects.

[0057] Furthermore, the image acquisition board 702 is installed into the card slot 701, and then the infrared thermal imager 7 is started. The infrared thermal imager 7 captures the infrared radiation on the surface of the waterproof rubber sleeve. When there are defects or uneven performance inside the waterproof rubber sleeve, it will cause abnormal surface temperature distribution. The infrared thermal imager 7 detects the infrared radiation on the surface of the waterproof rubber sleeve and converts it into an electrical signal, which is then transmitted to the image acquisition board 702. The image acquisition board 702 converts the electrical signal into a digital image signal, and then controls the display 702 to analyze and process the digital image, thereby identifying abnormal areas of temperature distribution on the surface of the waterproof rubber sleeve, and then determining whether the waterproof rubber sleeve has internal defects, and making a comprehensive evaluation of the stress distribution and material properties inside the waterproof rubber sleeve.

[0058] Furthermore, after the performance evaluation test of the waterproof rubber sleeve is completed, the dividing plate 203 is then rotated to transfer the waterproof rubber sleeve to one side of the unloading seat 9. At this time, the electric push rod 201 is started to push the waterproof rubber sleeve, so that the waterproof rubber sleeve can be pushed into the unloading seat 9. Then the waterproof rubber sleeve falls into the storage box 13 through the discharge pipe 11, and finally the waterproof rubber sleeve can be centrally stored and managed.

The indexing plate 203 is driven to rotate by the motor 202, and the placement plate 404 is rotated into the mounting plate 5;

[0062] Step S2: When the placement plate 404 is placed in the mounting plate 5, the pressure detection mechanism is lowered to apply pressure to the waterproof rubber sleeve, the pressure sensor 405 detects the magnitude of the applied pressure, the displacement sensor 406 detects the compression of the waterproof rubber sleeve, the measured tension and elongation of the waterproof rubber sleeve are measured, and the mechanical properties of the waterproof rubber sleeve under the compression load are analyzed;

[0063] Step S3: After the pressure detection is completed, when the pressure plate 402 is pressed onto the waterproof rubber sleeve, the second driving motor 401 drives the pressure plate 402 and the waterproof rubber sleeve to rotate, and applies torque to the waterproof rubber sleeve. The torque sensor 4 detects the torque size, and the angle sensor 403 detects the torsion angle, so as to evaluate the anti-torsion performance of the waterproof rubber sleeve and determine its torsion strength and torsion modulus parameters;
