Description

Technical Field

[0001] The present invention relates to the technical field of laser power supply detection, and more specifically, to a laser power supply performance detection device and a detection method thereof. Background Art

[0002] At a time when laser technology has fully penetrated into many fields such as industry, medical treatment, and scientific research, laser power supplies, as the core energy supply components of various types of laser equipment, play a decisive role in the effective operation of the entire system due to their stable and reliable performance. In actual use scenarios, laser equipment will face complex working conditions from many aspects, among which the continuous vibration generated during equipment operation is an extremely critical influencing factor.

[0003] In industrial manufacturing workshops, laser cutting and welding equipment will cause strong and irregular vibrations during high-frequency operation due to the operation of its own mechanical structure and the reaction force generated when processing materials. In the medical field, laser treatment equipment will also produce a certain degree of vibration when in use due to the coordinated work of the internal components of the equipment. High-end laser equipment in scientific research experiments has extremely high requirements for the stability of the operating environment. Any slight vibration may interfere with the accuracy of the experiment. Laser power supplies are the "power heart" of these devices. In a vibrating environment, the connection status between their internal components will be severely tested.

[0004] Although traditional laser power supply performance detection equipment can detect some conventional performance indicators, it has significant deficiencies in simulating actual vibration conditions. During the vibration process, complex situations such as changes in the connection status of key parts of the equipment are difficult to be effectively simulated and detected. For example, when the laser power supply is in a vibration environment, the internal connection state similar to a fixed structure will gradually change, thereby affecting its overall vibration characteristics. The difference in vibration response caused by this change in connection state will cause the laser power supply to have unstable output performance, such as output voltage fluctuations, current deviations, etc. However, since existing detection equipment cannot accurately simulate such conditions, a large number of laser power supplies that seem to be qualified in conventional tests frequently fail in actual vibration environments, seriously affecting the normal operation of laser equipment and increasing maintenance costs and downtime. Therefore, we have designed a laser power supply performance detection device and a detection method thereof. Summary of the invention

[0015] A method for detecting a laser power supply performance detection device comprises the following steps: S1. Sampling preparation: Take samples from the produced laser power supplies, place the laser power supply body to be tested on the vibration plate, and fix it with the threaded barrel on the vibration plate through bolts to ensure a stable installation; S2.

[0016] The beneficial effects of the present invention are: 1. The laser power performance detection device and detection method described in the present invention, through the cooperation of the relaxation mechanism and the extrusion mechanism, enable the laser power body to be detected under different loose and vibration states; not only can the vibration response data of the laser power under various working conditions be obtained, but also due to the simulated asymmetric looseness, the vibration response of the laser power presents asymmetric and uneven changes. These rich data changes provide a large amount of key information for fault diagnosis, which effectively assists technical personnel to quickly and accurately locate quality problems and significantly improve detection efficiency and quality.

[0017] 2. The laser power supply performance detection equipment and detection method described in the present invention, through the setting of sliders, racks and a special first unidirectional component, make the two sides of the laser power supply body fixed in different time periods and loosen to different degrees, highly simulating the actual situation where the bolts are loosened due to long-term uneven force or environmental influences; the extrusion mechanism cooperates closely with it, accurately matches the vibration amplitude according to the degree of looseness, and continuously increases the impact distance between the vibration plate and the mounting frame during the cyclic motion, continuously strengthens the vibration effect, and comprehensively and truly restores the state of the laser power supply under complex vibration conditions, providing highly practical conditions for detection, and greatly improving the reliability of the detection results.

[0018] 3.

DETAILED DESCRIPTION

[0021] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0022] like Figures 1 to 12As shown, a laser power performance detection device according to an embodiment of the present invention includes a test box 1 containing a box body 2; a mounting frame 301 is fixedly installed inside the box body 2 and connected to a vibration plate 607 through a toggle mechanism; a threaded barrel 605 is rotatably installed on the vibration plate 607 and connected to a laser power body 4 through a bolt 606; a protrusion 608 is fixedly installed at the bottom of the vibration plate 607; a relaxation mechanism is installed below the vibration plate 607, and during the reciprocating movement in the mounting frame 301, the laser power body 4 is loosened; a squeezing mechanism is installed below the relaxation mechanism, and when the laser power body 4 is loose, the laser power body 4 is vibrated, and the vibration amplitude matches the loose condition of the laser power body 4.

[0023] Specifically, the test chamber 1 is a high and low temperature alternating wet heat test chamber 1; when performing performance testing on the laser power supply body 4, the test chamber 1 can not only realize the alternation of high and low temperatures, but also accurately control the humidity changes, thereby simulating a variety of complex climatic conditions such as high temperature and high humidity, low temperature and low humidity; this feature enables us to perform simulated testing based on the actual use environment of the laser power supply body 4, and flexibly change the environment during the testing process, to further gain an in-depth understanding of the actual conditions of the laser power supply body 4 working in different environments.

[0024] When it is necessary to test the produced laser power source body 4, firstly, a sampling detection method is adopted to select a batch of laser power source bodies 4 to be tested; then, the laser power source body 4 is placed on the vibration plate 607 and fixed on the threaded sleeve with bolts 606; after the fixation is completed, the squeezing mechanism and the relaxation mechanism are started; wherein, the relaxation mechanism will first act on the threaded barrel 605 to make it rotate, thereby causing the bolts 606 to partially move out of the threaded barrel 605, causing the laser power source body 4 to loosen and the fixing effect to weaken; it should be noted that the loosening mechanism does not loosen the bolts 606 synchronously, but acts one by one, which leads to differences in the fixing effects on both sides of the laser power source body 4. When performing a vibration test, the vibration effects on both sides will also be different.

[0025] Subsequently, the squeezing mechanism starts to work, squeezing the protrusion 608, causing the protrusion 608 to drive the vibration plate 607 to move upward; the vibration plate 607 after moving upward returns to its original state under the action of the toggle mechanism, and collides with the mounting bracket 301, thereby generating vibration; the force generated by the vibration will be transmitted to the laser power supply body 4, causing it to collide with the vibration plate 607; the squeezing mechanism and the relaxation mechanism will perform reciprocating cyclic motion, continuously loosening the fixation on the laser power supply body 4, causing it to withstand stronger impact and vibration; at the same time, the squeezing mechanism will continue to increase the impact distance between the vibration plate 607 and the mounting bracket 301, further enhancing the impact effect, and acting on the laser power supply body 4 with a larger amplitude of vibration, thereby achieving more comprehensive detection.

[0026] There are two ways to detect the laser power supply body 4; one is to detect the laser power supply body 4 that is not powered on, the main purpose is to detect its basic quality condition; the other is to detect the laser power supply body 4 that is powered on, which requires cooperation with the detection module to complete; the detection module can collect various electrical parameter data of the laser power supply body 4 under vibration in real time, such as the output voltage, current stability, power fluctuation, etc.; through the analysis and comparison of these data, it is possible to promptly discover abnormalities that occur when the laser power supply body 4 works under a vibration environment, such as whether the circuit connection is loose, whether the performance of electronic components is degraded due to vibration, etc., thereby accurately locating the fault point of the laser power supply body 4, providing a strong basis for subsequent improvement and optimization.

[0027] After the detection is completed, the bolt 606 is rotated and removed, the detected laser power source body 4 is removed, and then the remaining laser power source bodies 4 to be detected are replaced and fixed, and the detection is cyclically performed in sequence according to the above process until the detection of all samples is completed.

[0028] Please refer to Figure 3 and Figure 8 and Fig.10 , a first slide groove is provided on the vibration plate 607; the relaxation mechanism includes a slider 602 slidably installed in the first slide groove; the rack 603 is located below the slider 602 and is fixedly connected to the slider 602 through a connecting plate 604; the first one-way component includes a support frame 702, and the support frame 702 is fixedly connected to the vibration plate 607; the first gear 704 is meshed with the rack 603, a tooth groove is provided through the center of the first gear 704, and the bottom of the first gear is rotatably connected to the support frame 702 through a rotating frame 706; the rotating plate 703 is fixedly installed on the support frame 702; the second rotating shaft 701 is rotatably installed on the rotating plate 703, and a toggle piece 705 is fixedly installed on the bottom of the second rotating shaft 701, which is located inside the tooth groove and the top of which is fixedly connected to the threaded cylinder 605; the sliding plate 601 is fixedly installed at the bottom of the rack 603 and is slidably connected to the extrusion mechanism.

[0029] When the extrusion mechanism reciprocates in the mounting frame 301, the sliding plate 601 drives the rack 603 to move, and the four racks 603 correspond to the four first gears 704. Due to the position setting of the first one-way component and the four racks 603, when the four racks 603 move in one direction at the same time, only two of the four racks 603 can enable the first gear 704 to drive the paddle plate 705 to rotate the second shaft 701, thereby rotating the threaded cylinder 605, while the remaining two racks 603 can only function during the return movement. During the return movement, the two racks 603 in the forward movement will lose their function. The fixing and loosening of the two sides of the laser power supply body 4 will not be carried out at the same time, but in time periods, so that the degree of relaxation on both sides will be different. By simulating the degree of relaxation of different bolts 606, it is possible to more realistically reflect the situations that the laser power supply body 4 may encounter in the actual working environment; for example, some bolts 606 may loosen first due to long-term uneven force or environmental influences, and this asymmetric relaxation has a significant effect on the vibration characteristics of the laser power supply body 4; and bolts 606 with different degrees of relaxation will cause asymmetric and uneven changes in the vibration response of the laser power supply body 4, and these changes can provide more information for fault diagnosis.

[0030] Please refer to 3 and Figures 7 to 9 The extrusion mechanism includes a fixed plate 309 slidably connected to the sliding plate 601; a first sliding rod 305 is fixedly installed inside the mounting frame 301; an auxiliary plate 308 is fixedly installed at the bottom of the fixed plate 309 and is slidably connected to the first sliding rod 305; a driving member 307 is fixedly installed at the bottom of the fixed plate 309 and is slidably connected to the first sliding rod 305; the second one-way component has the same structure as the first one-way component, and the two support frames 702 in the two second one-way components are fixedly connected to the auxiliary plate 308 and the driving member 307 respectively; the extrusion The pressure column 801 is slidably installed on the fixed plate 309, and a groove is opened inside the pressure column 801; the threaded block 803 is located inside the groove and is fixedly connected to the pressure column 801; the reciprocating screw 805 is threadedly connected to the threaded block 803, and its bottom is fixedly connected to the second rotating shaft 701 in the second one-way component; the third positioning plate 804 is fixedly installed on the pressure column 801, and the roller 802 is also rotatably installed on the third positioning plate 804; the fixing frame 807 is fixedly installed on the mounting frame 301, and a row of second latch teeth 806 are installed on one side of the inside.

[0031] When the fixed plate 309 moves left and right in the mounting frame 301, the fixed plate 309 will not only drive the sliding plate 601 and the rack 603 to move, but also move the roller 802 together. When the roller 802 moves to the specified position, the roller 802 will contact the protrusion 608, and then squeeze the protrusion 608, so that the protrusion 608 drives the vibration plate 607 to move upward, so that the vibration plate 607 vibrates with the toggle mechanism, and the vibration generated will be transmitted to the laser power supply body 4 to detect the laser power supply body 4; and when the fixed plate 309 moves, it will also drive the first gear 704 to move. When the first gear 704 moves to one side of the mounting frame 301, the second latch 806 on the fixed frame 807 will act on the first gear 704, so that the first gear 704 The second rotating shaft 701 is rotated by the toggle piece 705, and the second rotating shaft 701 drives the reciprocating screw 805 to rotate, and the reciprocating screw 805 drives the squeezing column 801 to move upward, so that the squeezing column 801 squeezes the protrusion 608 again, so that the upward movement distance of the vibration plate 607 will increase, so that the vibration generated after the vibration plate 607 moves downward will also increase, and the increase in vibration and the loosening of the bolt 606 are still mutually carried out, which can test the use of the laser power supply body 4 under harsh conditions with greater vibration, so as to test the quality problems of the laser power supply body 4, and because the second teeth 806 in the fixing frames 807 on both sides are installed at different positions, after the two sets of second one-way components move to the specified position, they will be acted upon by the second teeth 806 to move the roller 802 upward.

[0032] Please refer to Fig.12 A first slide groove is provided on the mounting frame 301; the toggle mechanism includes an extension column 311 fixedly connected to the vibration plate 607, and the extension column 311 is located inside the first slide groove and is slidably connected to the mounting frame 301; the first spring 310 connects the extension column 311 to the mounting frame 301.

[0033] After the extrusion mechanism moves the vibration plate 607 upward, with the help of the force of the first spring 310, the vibration plate 607 will immediately move downward and collide with the mounting bracket 301 after losing the upward force. The vibration generated by the collision will be transmitted to the laser power supply body 4, causing the laser power supply body 4 to undergo vibration detection.

[0034] Please refer to Figure 3 The extrusion mechanism also includes a mounting plate 302 fixedly connected to the mounting frame 301; a driving column 303 is rotatably mounted between the two mounting plates 302, and a track groove 306 is also opened on its surface; the bottom end of the driving member 307 is located in the track groove 306; the motor 304 is fixedly mounted on the mounting plate 302, and its power output shaft is fixedly connected to the driving column 303.

[0035] Start the motor 304, and the motor 304 will rotate the driving column 303 through the output shaft. The rotation of the driving column 303 will make the driving member 307 reciprocate on the driving column 303 with the help of the track groove 306 on its surface, so that the fixed plate 309 connected thereto will also reciprocate together, thereby achieving the effect of detecting the reciprocating vibration of the laser motor 304 body.

[0036] Please refer to Figures 3 to 5 and Fig.11 , the first positioning plate 508 is fixedly mounted on the vibration plate 607; the two driving plates 504 are fixedly mounted on the first positioning plate 508, and the two driving plates 504 are connected by the second magnetic block 510; the second positioning plate 511 is fixedly mounted on the driving plate 504, and is connected to the first positioning plate 508 through the second spring 506; the third sliding rod 507 is fixedly mounted on the first positioning plate 508, and is slidingly connected to the second positioning plate 511; the first latch tooth 505 is fixedly mounted on the driving plate 504; the third one-way component has the same structure as the first one-way component; the first rotating shaft 503 is fixedly connected to the second rotating shaft 701 in the third one-way component, and the top thereof is fixedly connected with the impact plate 501; the support column 502 is fixedly mounted on the mounting frame 301, and a row of first magnetic blocks 509 are fixedly mounted on its surface.

[0037] When the vibration plate 607 is continuously bumped and vibrated up and down by the combination of the roller 802 and the protrusion 608, the vibrated laser power source body 4 will also separate from the vibration plate 607 due to the vibration and the loosening of the bolt 606, so that the laser power source body 4 will be close to the impact plate 501, thereby colliding with the impact plate 501. In this way, the quality of the laser power source body 4 can be detected with the help of the impact of the impact plate 501, and different sizes of vibrations and the tightness of the bolt 606 will cause the laser power source body 4 to collide with the impact plate 501 in different ways, so that the effects produced will also be different, and the vibration plate 607 will drive the driving plate 504 and the second magnetic block 510 to move upward, and the upward movement of the second magnetic block 510 will interact with the first magnetic block 509, and the second magnetic block 510 and the first magnetic block 509 will repel each other magnetically, so that the second magnetic block 510 will drive the driving plate 504 and the first tooth 505 away from the second magnetic block 510, and the movement of the driving plate 504 will pass through the first magnetic block 509. A latching tooth 505 rotates the first gear 704 in the third one-way component, the first gear 704 rotates the second shaft 701, the second shaft 701 rotates the first shaft 503, and the first shaft 503 drives the impact plate 501 to rotate. Since the impact columns on the impact plate 501 are unevenly distributed, after the impact plate 501 rotates, the laser power source body 4 will be hit, and the impact columns that can contact it will also be different. In this way, the laser power source body 4 can be tested for impacts at different positions and densities, and the quality of the laser power source body 4 can be further tested. After each movement of the driving plate 504, it will return to its original position due to the second spring 506, so that when vibration occurs again, the impact plate 501 can continue to be driven to rotate. Finally, due to the process of the first magnetic block 509 and the second magnetic block 510 driving the driving plate 504, the driving plate 504 may also hit the side of the laser power source body 4, so that it can further improve the quality detection of the laser power source body 4 in different directions.

[0038] Please refer to Fig.13 , a detection method for laser power supply performance detection equipment, comprising the following steps: S1. Sampling preparation: Take appropriate amount of samples from the mass-produced laser power supplies according to certain sampling rules; the sampling rules can be determined according to relevant industry standards or statistical methods to ensure that the samples are representative.

[0039] The extracted laser power source body 4 to be tested is carefully placed on the vibration plate 607 , so that the mounting hole of the laser power source body 4 and the position of the threaded barrel 605 on the vibration plate 607 are precisely aligned.

[0040] Use the matching bolt 606, and screw the bolt 606 into the threaded barrel 605 according to the specified torque value through manual or automated tools to ensure that the laser power supply body 4 and the vibration plate 607 are firmly fixed and connected to prevent accidental falling off or displacement during subsequent testing.

[0041] S2. Environmental simulation: Start the high and low temperature alternating humidity test chamber 1, which is equipped with a high-precision temperature and humidity control system.

[0042] Through the operating interface of the test chamber, parameters such as temperature change range, heating / cooling rate, humidity change range and humidity adjustment accuracy can be accurately set according to the needs of the actual use scenario of the laser power supply. For example, if the laser power supply will be used in a high temperature and high humidity industrial environment, the temperature can be set from 20°C to 80°C within 2 hours, and the humidity can be set from 40% RH to 90% RH within 1 hour, and then maintained for a corresponding time before changing in the opposite direction, simulating a complex climate condition cycle.

[0043] The heating, cooling, humidification and dehumidification devices inside the test chamber work together to ensure that the temperature and humidity inside the chamber can change stably and accurately according to the set program, providing a realistic environmental simulation for laser power supply performance testing.

[0044] S3. Loosening and vibration operation: Turn on the relaxation mechanism, when the extrusion mechanism reciprocates in the mounting frame 301, it drives the sliding plate 601, and then moves the rack 603; due to the position setting characteristics of the first one-way component and the four racks 603, when the four racks 603 move in one direction at the same time, only two racks 603 can drive the first gear 704, so that the paddle plate 705 rotates the second shaft 701, thereby driving the threaded barrel 605 to rotate; this makes the bolts 606 on both sides of the laser power supply body 4 not loosen at the same time, but in time periods, simulating the situation where different bolts 606 are loosened to different degrees due to long-term uneven force or environmental influences.

[0045] Then, the squeezing mechanism starts to work; the fixed plate 309 moves left and right in the mounting frame 301, driving the sliding plate 601, the rack 603 and the roller 802 to move; when the roller 802 moves to the specified position, it contacts and squeezes the protrusion 608, so that the protrusion 608 drives the vibration plate 607 to move upward; after the vibration plate 607 moves upward, under the action of the toggle mechanism, it quickly moves downward with the elastic force of the first spring 310 and collides with the mounting frame 301, and the generated vibration is transmitted to the laser power supply body 4; at the same time, the movement of the fixed plate 309 drives the first gear 704 to move, and when the first gear 704 moves to one side of the mounting frame 301, the second latch 806 on the fixed frame 807 acts on the first gear 704, so that the second rotating shaft 701 rotates, driving the reciprocating screw 805 to rotate, and then the squeezing column 801 moves upward, squeezing the protrusion 608 again, increasing the upward movement distance of the vibration plate 607, increasing the vibration amplitude, and realizing a stronger vibration test on the laser power supply body 4.

[0046] S4, data acquisition: If the laser power supply to be tested is powered on, before the vibration test begins, the detection module is correctly connected to the corresponding circuit interface of the laser power supply body 4 to ensure that the detection module can accurately collect electrical parameter data.

[0047] When the laser power supply body 4 is in a vibrating state, the detection module uses high-precision sensors and data acquisition circuits to collect electrical parameter data such as its output voltage, current stability and power fluctuation in real time; the detection module digitizes the collected data and transmits it to the data processing terminal via wired or wireless communication.

[0048] The data processing terminal performs real-time analysis on the transmitted data, for example, by comparing with the standard electrical parameter range, it determines whether the output voltage is within the allowable fluctuation range, whether the current is stable, whether the power fluctuation exceeds the normal threshold, etc.; if abnormal data is found, the system will automatically mark and record the relevant data for subsequent in-depth analysis of problems that arise when the laser power supply body 4 works in a vibration environment, such as loose circuit connections, degraded performance of electronic components, etc.

[0049] S5. Cyclic testing: After a vibration test is completed, use a suitable tool to rotate the bolt 606 and completely unscrew it from the threaded barrel 605, and carefully remove the tested laser power supply body 4.

[0050] Check the vibration plate 607 and related components to ensure that there is no damage or foreign matter remaining; if necessary, clean the vibration plate 607 to ensure the accuracy of subsequent testing.

[0051] Replace the new laser power supply body 4 to be tested, repeat the above-mentioned steps of sampling preparation, environmental simulation, looseness and vibration operation, data collection, etc., and perform the test in a cycle in sequence; during the test process, continuously monitor the operating status of the test box, the working conditions of each component of the test equipment, and the accuracy of data collection until all sampling tests are completed.

[0052] Working principle: The laser power performance detection equipment is based on the test box 1, which is a high and low temperature alternating wet heat test box 1, which can simulate a variety of complex climatic conditions; after the laser power body 4 to be detected is placed on the vibration plate 607 and fixed to the threaded barrel 605 with bolts 606, each mechanism is started to start working; the slider 602 in the relaxation mechanism slides in the first slide groove of the vibration plate 607, driving the rack 603 to move. Due to the setting of the first one-way component, when the four racks 603 move in one direction at the same time, only two can make the first gear 704 drive the paddle plate 705 to drive the second shaft 701 to rotate, and then the threaded barrel 605 rotates, causing the bolt 606 to partially move out of the threaded barrel 605, causing the laser power body 4 to loosen, and the fixing and loosening of the two sides are not synchronized, which can simulate the uneven force on the bolts in actual work.

[0053] In the extrusion mechanism, the motor 304 drives the driving column 303 to rotate, and the track groove 306 on its surface makes the driving member 307 reciprocate between the mounting plate 302, driving the fixed plate 309 to move, thereby moving the sliding plate 601 and the rack 603. At the same time, the roller 802 moves and contacts and squeezes the protrusion 608, so that the vibration plate 607 moves upward, and cooperates with the extension column 311 and the first spring 310 in the toggle mechanism to make the vibration plate 607 collide with the mounting frame 301 to generate vibration and transmit it to the laser power supply body 4; and the fixed plate 30 When the first gear 704 moves, the first gear 704 is also driven to move. When the first gear 704 moves to one side of the mounting bracket 301, the second latching tooth 806 on the fixing bracket 807 acts on the first gear 704, so that the second rotating shaft 701 is driven to rotate through the shifting piece 705. The second rotating shaft 701 drives the reciprocating screw 805 to rotate. The reciprocating screw 805 drives the extrusion column 801 to move upward, and squeezes the protrusion 608 again, so that the upward movement distance of the vibration plate 607 increases, the vibration amplitude increases, and cooperates with the loosening of the bolt 606 to more comprehensively detect the laser power source body 4.

[0054] When the vibration plate 607 vibrates, it also drives the driving plate 504 and the second magnetic block 510 to move upward. The second magnetic block 510 and the first magnetic block 509 on the mounting frame 301 are magnetically repelled, so that the driving plate 504 and the first latch 505 are away from the second magnetic block 510. The driving plate 504 moves through the first latch 505 to rotate the first gear 704 in the third one-way component, driving the second rotating shaft 701 and the first rotating shaft 503 to rotate. The first rotating shaft 503 drives the impact plate 501 to rotate. Since the impact columns on the impact plate 501 are unevenly distributed, the laser power source body 4 can be subjected to impact detection at different positions and densities, and each time the driving plate 504 moves, the first gear 704 in the third one-way component rotates. 04 After moving, the second spring 506 returns it to its original position, so that it is convenient to continue to drive the impact plate 501 to rotate when vibration occurs again; when the laser power supply body 4 is powered on for detection, the detection module collects various electrical parameter data under vibration conditions in real time, such as the output voltage, current stability, power fluctuation, etc., and through analysis and comparison of these data, it can promptly discover abnormalities when the laser power supply body 4 works in a vibration environment and accurately locate the fault point; after the detection is completed, turn the bolt 606 to remove the laser power supply body 4, replace the remaining laser power supply bodies 4 to be detected and fix them, and repeat the detection until all sampling detection work is completed.
