DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 5 As shown, a laser power calibration device according to an embodiment of the present invention comprises a workbench 1, a first hydraulic cylinder 11 is arranged at the top of the workbench 1, a first connecting frame 13 is arranged at the side of the output end of the first hydraulic cylinder 11, a second hydraulic cylinder 14 is arranged at the top of the first connecting frame 13, a detector 12 is arranged at the end of the output end of the second hydraulic cylinder 14, a second connecting frame 15 adjacent to the first connecting frame 13 is arranged at the side of the output end of the first hydraulic cylinder 11, and a fixing piece is arranged at the top of the second connecting frame 15;

[0038] A support frame 18 is provided at the top of the fixing member, and a receiving tube 2 is provided at the top of the support frame 18, and the center line of the receiving tube 2 coincides with the center line of the receiving end of the detector 12; a plurality of temperature sensors 21 are provided in an annular shape on the side of the receiving tube 2, and the receiving end of the temperature sensor 21 passes through the inside of the receiving tube 2, and a heat conducting sheet 22 is provided at the receiving end of the temperature sensor 21; a partition 23 is provided between the receiving tube 2 and the detector 12;

[0039] In the actual laser power detection and calibration process, the staff needs to adjust the laser's transmitting head and the receiving end of the power detector to the same straight line to ensure the accuracy of the detection and calibration; during the specific adjustment, the staff needs to constantly adjust the position, which is difficult to adjust and is not conducive to optimizing the detection and calibration accuracy; to solve the above problems, the embodiment of the present invention is provided with a receiving tube 2, a temperature sensor 21 and other structures; the specific use process is as follows; when in use, the laser to be detected is placed on the top of the workbench 1, and then the transmitting head of the laser is preliminarily aligned with the receiving end of the detector 12, and then the laser is started, and the transmitting head of the laser emits a laser, and the laser is injected into the receiving tube 2, and the laser heats the heat conductive sheet 22 in the receiving tube 2, and the heat conductive sheet 22 transfers the heat to the receiving end of the temperature sensor 21, and the temperature sensor 21 determines the current temperature and transmits the data to the external computer through an electrical signal. Because the laser deviates from the center line of the receiving tube 2, the laser distance is different from the heat conductive sheet 2 2 There are differences in the energy of the received laser, and at the same time, the center line of the receiving tube 2 coincides with the center line of the receiving end of the detector 12; therefore, the staff can adjust the position of the detector 12 according to the values ​​displayed by different temperature sensors 21. During the specific adjustment, the height of the detector 12 is adjusted by the first hydraulic cylinder 11, and the horizontal position of the detector 12 is adjusted by the second hydraulic cylinder 14. When the values ​​displayed by different temperature sensors 21 are the same, it means that the laser distances are different and the heat conducting plates 22 are the same, that is, the center line of the laser coincides with the center line of the receiving tube 2; that is, it coincides with the center line of the receiving end of the detector 12; the detection and calibration requirements are met; the entire adjustment process is based on the detection of the temperature sensor 21, with high adjustment accuracy, convenient adjustment and low difficulty; it is conducive to optimizing the detection and calibration accuracy; it should be pointed out that during the adjustment, the partition 23 will block the laser from contacting the detector 12. After the adjustment is completed, the receiving tube 2 is removed and the detection is performed again to avoid the high-power laser from continuously acting on the detector 12 and causing damage to the detector 12.

[0040] The receiving tube 2 is made of high temperature resistant material, thereby increasing the service life of the receiving tube 2.

[0041] The fixing part includes a guide rail 16 and a third hydraulic cylinder 17.

The third hydraulic cylinder 17 is installed at the end of the guide rail 16, and the output end of the third hydraulic cylinder 17 is fixedly connected to the support frame 18. When the receiving tube 2 is removed, the third hydraulic cylinder 17 is started, and the output end of the third hydraulic cylinder 17 drives the support frame 18 to slide on the guide rail 16, and then drives the receiving tube 2 to move through the support frame 18, so as to prevent the partition 23 on the receiving tube 2 from blocking the contact between the laser and the detector 12, so as to facilitate the use of the staff.

[0042] like Figures 6 to 11As shown, a conveyor belt 3 is provided at the top of the workbench 1, and the conveyor belt 3 is used to convey the laser to be detected to the detection station; when the lasers are detected in batches, the conveyor belt 3 is controlled to run intermittently, and the lasers to be detected are placed on the conveyor belt 3 at equal intervals. The conveyor belt 3 stops when it drives the laser to the detection station, and is taken away from the detection station by the conveyor belt 3 after the detection is completed; the automation of detection is realized and the detection efficiency is improved; it should be pointed out that the position of the detector 12 at the detection station of the same batch of lasers has been adjusted, and it does not need to be adjusted again during batch detection.

The electromagnet 42 can drive the pad 31 to move up and down through the magnetic block 32, and the pad 31 maintains smooth movement through the connecting spring; the pad 31 drives the laser at the top to move up and down, so that the laser can meet the monitoring requirements of different heights; it can meet the detection and calibration of lasers of different models and sizes; after the detection is completed, the magnetic attraction between the electromagnet 42 and the magnetic block 32 is released; then the conveyor belt 3 drives the next laser to continue detection and calibration.

The air pump 65 is then started, and the air pump 65 inflates the annular airbag 63 through the air pipe 64. The inflated annular airbag 63 binds and fixes the plug.

The annular ring 62 drives the plug to move downward through the annular airbag 63 and is inserted into the socket of the power supply 61, thereby realizing automatic charging of the laser and improving the automation of the device.

[0049] like Figure 7 As shown, a buffer roller 71 is rotatably provided at one end of the receiving plate 7 close to the feeding end of the conveyor belt 3; in the process of the conveyor belt 3 driving the laser to move, the conductive wire drives the plug to move synchronously, and when the plug passes over the receiving plate 7, the buffer roller 71 at the end of the receiving plate 7 receives the plug to prevent the plug from being intercepted by the end of the receiving plate 7 and hindering the movement of the laser.
