Description

Technical Field

[0001] The present invention relates to the technical field of nuclear field detection equipment, and in particular to a detection device and a detection method for curling of gloves in a nuclear field glove box. Background Art

[0002] Glove boxes are widely used in nuclear facilities such as fuel element plants and reprocessing plants to handle radioactive materials. The sealing of the glove box is crucial to the health and safety of the operator, especially the sealing performance of the contact part between the glove and the glove box. According to the industry standard EJ / T1096, the sealing performance of the glove box must meet the level 1 sealing requirements, which requires the precise and reliable assembly of gloves, support rings, O-rings and receiving plates. However, the eligibility of the glove curling size directly affects the sealing performance of the overall device. If the curling size is uneven or substandard, the sealing effect will be significantly reduced, endangering safety.

[0003] At present, the curling of gloves is mostly done manually, which often results in uneven curling thickness and is difficult to meet the sealing requirements. In the prior art, there is no device or method specifically used to detect the eligibility of glove curling. Vernier calipers or thickness gauges are generally used to perform multi-point measurements instead. These traditional methods have significant shortcomings:

[0004] 1. Low measurement efficiency: Due to the uneven size of the glove hem, it is necessary to measure multiple locations multiple times, which is cumbersome and time-consuming.

[0005] 2. Large measurement error: Gloves are elastic, and the results may be inconsistent due to tightening or loosening during measurement. In addition, it is difficult to ensure that the vernier caliper is perpendicular to the rolled edge, resulting in large deviations in the measurement results.

[0006] 3. Operational complexity: Traditional measuring tools require high technical proficiency of the operator, and due to the simple structure of the equipment, the wear of mechanical parts will further reduce the measurement accuracy.

[0007] In view of the above problems, the present invention is proposed. Summary of the invention

[0008] The invention discloses a detection device and a detection method for curling of gloves in a nuclear field glove box, aiming to solve the technical problems existing in the prior art.

[0009] According to one aspect of the present invention, a device for detecting curling of gloves in a nuclear field glove box is provided, comprising a control subsystem, a transmission subsystem and a distance measuring subsystem, wherein the control subsystem, the transmission subsystem and the distance measuring subsystem are integrated into one;

[0010] Control subsystem, used for control operation and data acquisition;

[0011] The transmission subsystem is provided with a first test end, a sliding assembly, at least one slide rail, a screw rod and a motor. The first test end is arranged above the sliding assembly, and the plane where the first test end is located is perpendicular to the plane where the top surface of the sliding assembly is located; both sides of the sliding assembly are connected to the slide rails; a through hole is provided at the bottom of the sliding assembly, one end of the screw rod is connected to the motor, and the other end passes through the through hole;

[0012] The distance measuring subsystem is provided with a second test end, a pressure gauge, and a laser distance measuring sensor, wherein the pressure gauge is connected to the second test end and is fixedly arranged above the laser distance measuring sensor;

[0013] The second test end is arranged in parallel with the first test end. During detection, the first test end moves toward the second test end so that the pressure gauge and the laser distance sensor can perform distance measurement.

[0014] As a preferred technical solution, the control subsystem is provided with a display screen and operation buttons. The display screen displays and collects the detection data, and the operation buttons control the operation of the transmission subsystem and the distance measurement subsystem.

[0015] As a preferred technical solution, the sliding component is provided with a sliding component body and a slider, the upper portion of the sliding component body is connected to at least one slider, the slider is connected to the slide rail, and a through hole is provided at the lower portion of the sliding component body.

[0016] As a preferred technical solution, two sides of the upper part of the sliding assembly body are connected to two sliding blocks.

[0017] As a preferred technical solution, there are two slide rails, which are arranged in parallel and are parallel to the lead screw.

[0018] According to another aspect of the present invention, a method for detecting the curling of gloves in a glove box using the above-mentioned detection device is provided, comprising:

[0019] Turn on the detection device switch and set the alarm threshold of the control subsystem and the range of the pressure gauge;

[0020] Operate the operation button to move the first detection end in a direction away from the second detection end;

[0021] Install the glove to be tested between the first testing end and the second testing end;

[0022] Wait for a certain period of time or operate the operation button to make the first detection end continue to move in the direction close to the second detection end;

[0023] When the pressure gauge reaches the preset range, the first detection end stops moving and the laser distance sensor performs distance measurement;

[0024] The control subsystem determines whether the alarm threshold is exceeded: if exceeded, the control subsystem sounds an alarm, the glove hem fails, and the test is terminated; if not exceeded, the process of repeatedly performing the steps of installing the glove to be tested to the step of measuring the distance with the laser ranging sensor is repeated, and if the control subsystem does not alarm, the glove hem passes and the test is completed.

[0025] As a preferred technical solution, the number of cycles from the step of installing the gloves to be detected to the step of measuring the distance with the laser ranging sensor is n=n+1, and n0=0.

[0026] As a preferred technical solution, when n is less than 5, the cycle continues.

[0027] As a preferred technical solution, after the laser ranging sensor measures the distance, the first detection end moves away from the second detection end, and the glove is removed.

[0028] As a preferred technical solution, the ranging time of the laser ranging sensor is 1 s.

[0029] The technical solution adopted by the present invention can achieve at least one of the following beneficial effects:

[0030] 1.

[0031] 2. The present invention optimizes the structure of the sliding assembly, ensures a smooth sliding process through the cooperation between the slider and the slide rail, and realizes precise displacement control through the linkage of the screw rod and the motor. At the same time, the control subsystem is equipped with a display screen and operation buttons to make data collection and equipment operation more intuitive and convenient. The application of multiple preferred technical solutions, such as the parallel dual slide rail design and the precise sliding assembly structure, further improves the mechanical stability of the device and the convenience of user operation, meeting the detection needs in multiple scenarios.

[0032] 3. The detection device of the present invention greatly improves the automation of quality detection through intelligent control logic and cyclic detection method. During the detection process, the control subsystem can make real-time adjustments based on the feedback from the pressure gauge and laser range sensor and determine whether the set threshold is exceeded. When unqualified gloves are found, an alarm can be immediately issued and the detection can be stopped to ensure the accuracy and reliability of each detection. Combined with the preferred scheme of cyclic multiple detection, the device can quickly batch detect the quality of the glove curling, greatly reducing the detection time and labor costs, while ensuring the consistency of the detection results.

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. In the description of the present invention, it should be noted that the term "or" is usually used in the sense of including "and / or", unless the content clearly indicates otherwise.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a nuclear field glove box glove curling detection device, such as Figure 1-Figure 3 As shown, it includes a control subsystem 1, a transmission subsystem 2 and a distance measuring subsystem 3. The control subsystem 1 is used for accurate coordination and control of the transmission subsystem 2 and the distance measuring subsystem 3, as well as alarm function control. By receiving data fed back by the distance measuring subsystem, the movement of the transmission subsystem is adjusted; the detection device is controlled to sound a whistle alarm under specific conditions to ensure that the glove box glove curling detection process is accurate; the transmission subsystem 2 uses its mechanical movement to ensure that the glove box gloves are smoothly transferred to the detection position of the distance measuring subsystem during the detection process; the distance measuring subsystem 3 is a key component for performing the curling detection function, which is used to measure the size, shape and other characteristics of the glove box glove curling in real time, and transmit the measurement data to the control subsystem 1. Based on the above data, the control subsystem 1 determines whether the glove box glove curling meets the predetermined specifications to help achieve quality control.

[0044] like Figure 1 and Figure 2 As shown, the control subsystem 1, the transmission subsystem 2 and the distance measurement subsystem 3 are integrated into one. The control subsystem 1 includes a display screen 11 and an operation button 12, which respectively perform data display and semi-automatic control operations, so as to effectively reduce the error introduced by human operation and greatly improve the accuracy. The transmission subsystem 2 is provided with a first test end 21, a sliding assembly 2, a slide rail 23, a screw rod 24 and a motor 25. Figure 1 and Figure 2The first test end 21 is vertically mounted on the sliding assembly 22. The sliding assembly 22 is provided with a sliding assembly body 221 and a slider 222. The first test end 21 is vertically mounted on the upper surface of the sliding assembly body 221. The upper part of the sliding assembly body 221 is in the shape of a rectangular parallelepiped, and the lower surfaces of the two ends of the rectangular parallelepiped are respectively connected to the slider 222. Figure 2 As shown, the two sliders 222 are connected to the two lower slide rails 23 respectively; Figure 2 As shown, a through hole is provided at the lower part of the sliding component body 221, and the screw rod 24 passes through the through hole and is connected to the motor 25. The axial direction of the screw rod 24 is perpendicular to the plane direction where the first detection end 21 is located and the plane direction where the upper and lower surfaces of the upper part of the sliding component body 221 are located.

[0045] When the first test end 21 needs to be moved, the motor 25 drives the screw 24 to rotate and drives the sliding component body 221 to move along the two side rails 23. The moving direction of the first test end 21 and the sliding component body 221 is the same as the axial direction of the screw 24 to complete the transmission.

[0046] like Figure 3 As shown, the distance measuring subsystem 3 is provided with a second test end 31, a pressure gauge 32, a laser distance measuring sensor 33 and a bracket 34. The second test end 31 is arranged in parallel with the first test end 21, and is connected to the pressure gauge 32, and is fixedly mounted on the bracket 34. A laser distance measuring sensor 33 is arranged directly below the pressure gauge 32 for detecting and providing detection data.

[0047] Through the above structural design, the control subsystem 1, the transmission subsystem 2 and the distance measurement subsystem 3 are integrated to achieve efficient and accurate curling detection. The control subsystem 1 receives the distance measurement data and coordinates the movement of the transmission subsystem 2 to ensure the accuracy of the detection process, and supports data display and semi-automatic operation to reduce human errors. The transmission subsystem 2 drives the screw 24 to rotate through the motor 25, driving the sliding assembly 22 and the first test end 21 to move smoothly along the slide rail 23, and transferring the glove box glove to the distance measurement position. The distance measurement subsystem 3 uses the laser distance measurement sensor 33 and the pressure gauge 32 to detect the size and shape of the curling of the glove box gloves in real time, and feeds the data back to the control subsystem 1 for analysis to determine whether it meets the predetermined specifications, thereby realizing automated quality control and significantly improving the detection efficiency and accuracy.

The maximum and minimum values ​​of the curling diameter of the glove box gloves can be set according to actual needs; the curling diameter of gloves on the market is required to be 5 mm, and the error range is generally ±1 mm, and some high requirements can reach ±0.5 mm.

[0053] In some preferred embodiments, the pressure of the pressure gauge 32 is set to 3±0.5 N. This parameter is based on a comprehensive consideration of multiple factors such as the properties of the rubber material, measurement accuracy and repeatability, measurement principles and instrument characteristics, practical experience and standards, and specific application scenarios to improve the accuracy, stability and reliability of the test results.

[0061] S6: within 1 second, the laser distance measuring sensor 33 measures the distance between the first test end 21 and the second test end 31;

[0062] At the same time, the first test end 21 moves away from the second test end 31 until the parameter of the pressure gauge 32 is 0, and then the glove box gloves are taken out;

[0063] S7: The control subsystem 1 determines whether the test result exceeds the threshold value: if it exceeds, the control subsystem 1 controls the detection device to sound a whistle to alarm, the detection is terminated, and the curling of the glove box gloves is determined to be unqualified; if it does not exceed, the above steps S3-S7 are repeated multiple times, and no alarm is issued, then the curling of the glove box gloves is determined to be qualified.
