In manufacturing, they serve as high-intensity light sources for cutting, drilling, and welding.

[0003] Currently, quality testing is a crucial step in the fiber laser production process, directly impacting the quality of the fiber laser. Traditional fiber laser testing typically involves multiple testing positions, requiring manual input of test data after each position completes the testing for archiving and later traceability. However, this method necessitates data transfer between multiple positions, resulting in low testing efficiency. Furthermore, manual data input is highly prone to errors, thus affecting the final test results. Utility Model Content

Its purpose is to not only effectively improve the testing efficiency, but also avoid the situation of inputting errors when manually entering various test data, thus ensuring the reliability of the test data.

[0008] Optionally, the support frame has a clearance opening for obstructing the fiber optic splice at the bottom of the fiber laser; The thermal imaging test assembly consists of two components: one thermal imager is used to test the temperature of the fiber optic splice at the top of the fiber laser, and the other thermal imager is used to test the temperature of the fiber optic splice at the bottom of the fiber laser.

[0009] Optionally, the three-dimensional displacement module includes a first linear module, a second linear module, and a third linear module. The first linear module is located on the support frame. The first linear module is used to drive the second linear module to move along a first direction.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] Example: Figure 1 This is a schematic diagram of a testing device for fiber lasers provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the testing device includes a support frame 1, a power meter 2, a spectrometer 3, and a data storage module 4.

[0026] Figure 2 This is a schematic diagram of the testing device provided in this embodiment of the invention without a partial outer cover. Figure 2 As shown, the support frame 1 is used to support the fiber laser 100. The power meter 2, the spectrometer 3, and the data storage module 4 are arranged at intervals on the support frame 1. The power meter 2 is used to test the power of the fiber laser 100, the spectrometer 3 is used to test the spectrum of the fiber laser 100, and the data storage module 4 is electrically connected to the power meter 2 and the spectrometer 3 respectively (through wireless or cable signal transmission) to receive and store the test data.

[0027] In the testing device for fiber lasers provided in this embodiment of the invention, when testing the fiber laser 100, firstly, the fiber laser 100 is placed on the support frame 1, and the laser output head is inserted into the fiber laser 100. Then, the fiber laser 100 is started, and the laser output head outputs the laser sequentially to the power meter 2 and the spectrometer 3. The spectrometer 3 can test the laser spectrum, while the power meter 2 can test the laser output power. This allows for the testing of the spectrum and output power at the same workstation, avoiding the need to transfer the fiber laser 100 between different workstations, thereby improving testing efficiency. Finally, the spectrometer 3 transmits the measured spectral data and the power meter 2 transmits the measured output power data to the data storage module 4 in a timely manner and stores these test data. This avoids the situation where manual input of various test data is prone to errors, thus ensuring the reliability of the test data.

[0028] In other words, the testing device for fiber lasers provided by this utility model embodiment can not only effectively improve testing efficiency, but also avoid errors when manually inputting various test data, thus ensuring the reliability of test data.

[0029] In addition, this testing device can better preserve various test data during the production process of fiber laser 100, avoiding data loss. At the same time, by concentrating all testing stations on a support frame 1, it can also save manpower, improve production efficiency, and increase economic benefits.

[0030] For example, the data storage module 4 can be a semiconductor memory or a magnetic surface memory, and the present invention does not limit it in this regard.

[0031] In one implementation of this utility model, a plurality of positioning blocks (not shown) are provided on the support frame 1. The positioning blocks are arranged at intervals and form a positioning space for positioning the fiber laser 100. The positioning blocks can position the fiber laser 100 and prevent it from moving accidentally during testing.

[0032] In addition, the testing device also includes a display 6, which is electrically connected to the data storage module 4. The display 6 can display the test data stored in the data storage module 4 in real time for easy presentation. Furthermore, the display 6 can also function as a controller, i.e., inputting control commands. The display 6 is electrically connected to the fiber laser 100, power meter 2, and spectrometer 3, thereby enabling start / stop control and power adjustment control of multiple modules.

[0033] In this embodiment, the testing device also includes an outer cover 7, which is mounted on the support frame 1. The power meter 2, the spectrometer 3, and the data storage module 4 are located inside the outer cover 7.

[0034] In the above embodiments, the outer cover 7 can cover the power meter 2, the spectrometer 3 and the data storage module 4, playing a protective role and avoiding human contact during the detection process.

[0035] For example, the outer casing 7 is provided with multiple through holes and movable doors to facilitate light transmission and the placement and removal of the fiber laser 100. The display 6 is fixed on the support frame 1 and located outside the outer casing 7.

[0036] For example, the bottom of the support frame 1 is provided with a plurality of spaced rollers 8, which facilitates the transportation of the support frame 1.

[0037] In one embodiment of this utility model, the support frame 1 includes a first support surface 11 and a second support surface 12. The first support surface 11 is located above the second support surface 12 and is used to support the fiber laser 100. The power meter 2, the spectrometer 3 and the data storage module 4 are arranged at intervals on the second support surface 12.

[0038] In the above embodiment, the fiber laser 100, power meter 2, spectrometer 3 and data storage module 4 are supported by the first support surface 11 and the second support surface 12 respectively, thereby achieving a layered arrangement, making the overall structure more compact and reducing the space occupied by the test device.

[0039] For example, the first support surface 11 and the second support surface 12 are arranged in parallel at intervals.

[0040] See Figure 1 and Figure 2The testing apparatus also includes a thermal imaging testing component 5, which comprises a thermal imager 51 and a three-dimensional displacement module. The thermal imager 51 is used to test the temperature of the fiber optic splice in the fiber laser 100. The three-dimensional displacement module is located on the support frame 1 and is used to drive the thermal imager 51 to move along a first direction (X-axis), a second direction (Y-axis), and a third direction (Z-axis). The three-dimensional displacement module can adjust the spatial position of the thermal imager 51, allowing it to detect fiber optic splices at different locations and preventing excessively high splice temperatures from affecting the performance of the fiber laser 100.

[0041] In other words, the thermal imaging testing component 5 provided by this utility model can further test the temperature of the fiber fusion splice in the fiber laser 100, and can detect problems in time and rework (i.e. re-fusion splice).

[0042] In this embodiment, the support frame 1 has a clearance opening 13, which is used to avoid obstructing the fiber optic splice at the bottom of the fiber laser 100. Additionally, there are two thermal imaging test components 5: one thermal imager 51 is used to test the temperature of the fiber optic splice at the top of the fiber laser 100, and the other thermal imager 51 is used to test the temperature of the fiber optic splice at the bottom of the fiber laser 100.

[0043] It should be noted that for fiber lasers 100 of different models or sizes, due to the different placement positions of the water-cooling plate and pump source, the corresponding multiple fiber fusion splices may be arranged only on the top of the fiber laser 100, or they may be arranged on both the top and bottom of the fiber laser 100, resulting in two different testing conditions. Therefore, by setting up two thermal imaging testing components 5, not only can the fiber fusion splices on the top be tested individually (the other thermal imaging testing component 5 does not need to operate at this time), but the fiber fusion splices on the top and bottom can also be tested simultaneously, thereby increasing the applicability of this testing device. In addition, the clearance port 13 can avoid the bottom of the fiber laser 100, so that the fiber fusion splices on the bottom will not interfere, facilitating the detection of the thermal imager 51.

[0044] For example, the two thermal imaging test components 5 are respectively disposed on the first support surface 11 and the second support surface 12, thereby achieving a layered arrangement, which not only facilitates installation but also prevents the two three-dimensional displacement modules from interfering with each other during displacement. In addition, the clearance 13 is located on the first support surface 11.

[0045] Furthermore, the three-dimensional displacement module includes a first linear module 521, a second linear module 522, and a third linear module 523. The first linear module 521 is located on the support frame 1. The first linear module 521 drives the second linear module 522 to move along a first direction, the second linear module 522 drives the third linear module 523 to move along a second direction, and the third linear module 523 drives the thermal imager 51 to move along a third direction. Therefore, the first linear module 521 can drive the thermal imager 51 to move along the X-axis, the second linear module 522 can drive the thermal imager 51 to move along the Y-axis, and the third linear module 523 can drive the thermal imager 51 to move along the Z-axis, thereby ultimately realizing the position adjustment of the thermal imager 51 in three-dimensional space.

[0046] It should be noted that the three-dimensional displacement module can also be configured in other structural forms, and this utility model does not limit this.

[0047] In addition, a lifting module 14 is provided on the support frame 1, and the first linear module 521 is located on the lifting module 14.

[0048] It is easy to understand that the lifting module 14 can lift the first linear module 521 in the Z-axis direction, thereby reducing the stroke of the third linear module 523 and reducing the load on the first linear module 521.

[0049] For example, the lifting module 14 may include a plurality of parallel spaced support plates, and the first linear module 521 is disposed on the plurality of support plates.

[0050] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
