The signal ring 8 with the structure of the plurality of arc-shaped grooves 9 can enable the device to have a plurality of application scenes. The number of the shielded photodetectors 7 is different, and signals output by the identification circuit 6 are different, so that the light spot position measurement system has more testing capability. Such a hand tool is used for a laser of 1um wavelength, for example when the number of arcuate grooves 9 on the signal ring 8 is 1; when the number of arc-shaped grooves 9 on the signal ring 8 is 2, such a device is used for a 532nm wavelength laser. Since the output signals of the identification circuit 6 of the 1 arc-shaped groove 9 are different from the output signals of the identification circuit 6 of the 2 arc-shaped grooves 9, when the device of the 1 arc-shaped groove 9 is used for a 532nm laser, the identification circuit 6 directly alarms due to the fact that the output signals of the identification circuit 6 are not opposite, and the misuse of the device can be avoided.
Example 2
The present embodiment provides a method for using the device for adjusting and identifying a laser spot in embodiment 1, the method for using the device includes the following steps:
Step one: aligning a first photodetector 7 (i.e., D1) on the identification circuit 6 with an arcuate recess 9 on the signal ring 8, where the distance between the focusing lens 4 and the output port 2 is furthest;
Step two: rotating the adjusting part 3, when the identifying circuit 6 outputs a signal of the mth light sensing detector 7 (namely Dm), and at the moment, the Dm on the identifying circuit 6 is aligned with the arc-shaped groove 9 on the signal ring 8, recording the size Zm of the output light spots, and the size m is more than or equal to 2 and less than or equal to n, repeatedly recording the values of the n output light spots, and pre-storing the values as pre-stored values of the current device model;
Step three: in the process of using a device of a certain model, when the identification circuit 6 outputs the signal of the mth light sensing detector 7 for the first time, the identification circuit 6 judges the number of the light sensing detectors 7 in the device of the model, and compares the number with a prestored value of the device of the model to obtain the wavelength of laser output by the device of the model; the required output light spot value is input into the identification circuit 6, the identification circuit 6 automatically searches the information corresponding to the light sensing detector 7 according to the prestored value of the model device, the adjusting part 3 is rotated, and when the information of the light sensing detector 7 output by the identification circuit 6 is consistent with the information searched by the identification circuit 6, the identification circuit 6 gives a prompt, the model device is indicated to be adjusted to the required output light spot value, and the rotating adjusting part 3 is stopped.
In this example, for example, when n=5, we obtain the data in the following table
| The recognition circuit 2 outputs the information of the photodetector | Hand tool output light spot size (mm) |
| D1 | 2 |
| D2 | 3 |
| D3 | 4 |
| D4 | 5 |
| D5 | 6 |
Meanwhile, the number of the arc grooves 9 on the signal ring 8 can be used as the model of the current device, for example, in the embodiment, the number of the arc grooves 9 is one, and then the output wavelength corresponding to the device is the fundamental frequency wavelength of the laser.
In this embodiment, when n is sufficiently large, for example, when n=t, the photodetector 7 on the identification circuit 6 only needs to rotate a small distance at this time to output the signal of the photodetector 7, so that the position of the focusing lens 4 can be positioned with high precision, and thus the size of the output light spot can be regulated with high precision.
In addition, the number of the arc-shaped grooves 9 on the signal ring 8 can be multiple, for example, the number of the arc-shaped grooves 9 is two, the positions of the two arc-shaped grooves 9 on the signal ring 8 are consistent with the positions of any two light sensing detectors 7 on the identification circuit 6, and the arc-shaped grooves 9 can be guaranteed to cover the two light sensing detectors 7 at the same time. The signal ring 8 with the design structure of the plurality of arc-shaped grooves 9 can enable the adjusting and identifying device of the laser light spots to adapt to various application scenes. Because the number of the shielded photodetectors 7 is different, the signals output by the identification circuit 6 are different, so that the spot position measurement system has more testing capability, for example, when the arc-shaped grooves 9 on the signal ring 8 are one, the laser spot adjusting and identifying device is used for a laser with the wavelength of 1 um; when the number of the arc-shaped grooves 9 on the signal ring 8 is two, the adjusting and identifying device for the laser spots is used for a 532nm wavelength laser; because the output signal of the identification circuit 6 of one arc-shaped groove 9 is different from the output signals of the identification circuits 6 of two arc-shaped grooves 9, when the adjusting and identifying device of the laser light spots of one arc-shaped groove 9 is used for a laser with the wavelength of 532nm, the identification circuit 6 can give an alarm at the moment because the number of the output signals of the identification circuits 6 is not correct, and the error of the adjusting and identifying device of the laser light spots can be avoided.

When in use, the output number of the Dm signals is judged according to the identification circuit 6, and compared with pre-stored data, the adjustment and identification device of the laser light spot with the frequency doubling function is obtained, and therefore the output laser wavelength is the frequency doubling wavelength of laser output laser of the laser.

By the relative rotation of the fixing portion 1 and the adjusting portion 3, the distance between the concave lens 15 and the focusing lens 4 is changed, so that the size of the spot of the laser light on the honeycomb lens 16 is changed, so that the output spot size of the device is changed.
The number of the arc-shaped grooves 9 on the signal ring 8 of the adjusting and identifying device for the laser light spot of the embodiment may be different from that of the embodiment 1, for example, the number of the arc-shaped grooves 9 on the signal ring 8 in the embodiment 1 is one, and three arc-shaped grooves 9 in the embodiment may be arranged on the signal ring 8, and the positions of the three arc-shaped grooves 9 are consistent with the positions of any three light sensing detectors 7 on the identifying circuit 6;
