At the same time, the image data of the laser light beam is collected by the industrial camera 13 and displayed on the display screen 15. There is no need to observe the center point of the laser light beam with the naked eye, which avoids the subjective error of the human eye's visual collimation correction, improves the consistency of the correction, effectively protects eyesight, and avoids the potential harm of laser to the human eye.

[0029] In other embodiments, the clamping mechanism 3 includes a clamping seat 31, an arc-shaped clamping groove 32 is provided in the clamping seat 31, the laser body 4 is arranged inside the arc-shaped clamping groove 32, and an adjustment groove 33 is provided above the arc-shaped clamping groove 32. When the laser body 4 is clamped and fixed, the laser body 4 is initially placed inside the arc-shaped clamping groove 32 to preliminarily position it.

[0030] In other embodiments, two electric push rods 35 are installed on the top of the clamping seat 31. The piston rod ends of the two electric push rods 35 pass through the clamping seat 31 and are commonly connected to an arc-shaped clamping plate 34.

[0032] In other embodiments, a heat sink 7 is embedded in the correction auxiliary box 5, and the heat sink 7 is arranged on one side of the power attenuation reflector 9. The mirror surface of the power attenuation reflector 9 forms an angle of 45° with the propagation direction of the laser beam. The high-power laser beam emitted by the laser body 4 can be reflected by the power attenuation reflector 9, and most of the laser beam will be reflected.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the present invention, the laser body 4 is initially placed inside the arc-shaped clamping groove 32, and initially positioned, and then the electric push rod 35 is started. The piston rod of the electric push rod 35 is extended to drive the arc-shaped clamping plate 34 to move downward until it fits with the laser body 4, and the position of the laser body 4 is fixed. The laser body 4 is started, and the laser body 4 emits a laser beam. The laser beam enters through the light inlet 6 of the correction auxiliary box 5, and then is collimated by the collimating lens 8 to output a parallel beam, and then is reflected by the power attenuation reflector 9. At this time, most of the laser beam will be reflected, and the reflected laser beam can be absorbed by the radiator 7; afterwards, a very small part of the low-power laser beam is transmitted through the power attenuation reflector 9. , which can attenuate the energy of a high-power laser beam into a safe and measurable low-power laser beam, and then pass it through the focusing lens 10, focus it using the focusing lens 10, and then irradiate it to the industrial camera 13 through the lens 14, and then perform image acquisition through the industrial camera 13, and then receive the data of the industrial camera 13 through the PLC controller 16, and display it on the display screen 15 in the form of data. If the laser light path meets the standard, no debugging is required. When the image data collected by the industrial camera 13 is offset, the light path does not meet the standard. The operator uses an external fiber optic collimator and other adjustment devices to adjust the laser body 4 so that the laser beam emitted by the laser body 4 is more parallel until the light path meets the standard.

[0038] It should be noted that the specific model specifications of the laser body 4, PLC controller 16, electric push rod 35, industrial camera 13, display screen 15 and electric slide 19 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Their power supply, specific composition and principles are clear to technical personnel in this field and are common knowledge in this field, so they will not be described in detail.
