The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a cleaning gun head of a laser cleaning device, such as Figure 1-5 As shown, it includes a laser cleaning gun head body 1, a laser emitting cavity 2 is provided on one side outer wall of the laser cleaning gun head body 1, a laser emitting lens 3 is embedded in the central position of the laser emitting cavity 2, a through groove 4 is provided on one side outer wall of the laser cleaning gun head body 1 adjacent to the laser emitting cavity 2, two through grooves 4 are provided, and the two through grooves 4 are symmetrically provided on the outer side wall of the laser cleaning gun head body 1, a light blocking plate 5 passes through the inside of the through groove 4, and a light absorbing layer 6 is provided on one side outer wall of the light blocking plate 5 near the inner side of the laser emitting cavity 2, and the light absorbing layer 6 faces the laser emitting lens 3 The emitting end, the top and bottom of the light baffle 5 are integrally formed with a limit strip 7, a fastening nut 8 is screwed together at a position on one side of the outer wall of the laser cleaning gun head body 1 close to the laser emitting cavity 2, one end of the fastening nut 8 is located inside the through groove 4, a scale line 9 is arranged on the outer wall of one side of the laser cleaning gun head body 1 close to the lower position of the laser emitting cavity 2, the outer walls of the four sides of the laser cleaning gun head body 1 adjacent to the laser emitting cavity 2 are fixedly connected with an inclined mounting platform 10 by screws, and a thermal infrared sensor 11 is embedded on the outer wall of one side of the inclined mounting platform 10.

[0023] It should be noted that since the width of the laser beam emitted by the existing laser cleaning gun head is not easy to adjust, a laser beam with a longer width may irradiate some soft materials and cause damage to the workpiece. In this embodiment, the light blocking plate 5 with an adjustable position on one side of the laser emitting lens 3 can control the distance between the two light blocking plates 5 to achieve the effect of adjusting the laser beam emission width, thereby cleaning some parts of the workpiece and avoiding the problem that the laser beam will irradiate some soft materials and cause damage to the workpiece. The thermal infrared sensor 11 is used to perform thermal detection on the outer inclination angle of the laser emitting lens 3 to avoid the problem that the laser cleaning gun head body 1 is irradiated to the human body due to improper operation during operation, causing human injury.

[0024] Specifically, in this embodiment, this scheme mainly includes a light baffle 5. When it is necessary to adjust the width of the laser beam emitted by the laser cleaning gun head body 1, the light baffle 5 is moved in the through groove 4, and the distance between the two light baffles 5 is adjusted according to the markings of the scale lines 9. When the distance between the two light baffles 5 is the same as the width of the laser beam to be adjusted, the fastening nut 8 is rotated, and the threaded connection between the fastening nut 8 and the laser cleaning gun head body 1 is achieved. One end of the fastening nut 8 is squeezed on the light baffle 5 to fix the position of the light baffle 5, thereby achieving the adjustment of the width of the laser beam, and the laser emission is adjusted. The shooting lens 3 emits a laser beam, a part of which is absorbed by the light absorbing layer 6, and the other part is emitted through the gap between the two light blocking plates 5, so as to make adaptive adjustments according to the local cleaning width of the workpiece. When the laser cleaning gun head body 1 is in use, hold the laser cleaning gun head body 1, and the thermal infrared sensor 11 performs thermal detection on the outer inclination angle of the laser emission lens 3. When the thermal infrared sensor 11 detects the heat of the human body, the laser cleaning equipment cuts off the power supply of the laser emission lens 3, thereby avoiding the problem of the laser cleaning gun head body 1 irradiating the human body due to improper operation during operation, causing human injury.

[0025] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 5 As shown, the laser emission cavity 2 and the through slot 4 are connected, and the inner top and inner bottom of the laser emission cavity 2 and the through slot 4 are both provided with limiting grooves matching with the limiting strip 7 .

[0026] In this embodiment, the limiting groove limits the limiting strip 7 , thereby ensuring the stability of the movement of the light blocking plate 5 in the through slot 4 , and enabling the light blocking plate 5 to pass through the through slot 4 and be inserted into the laser emission cavity 2 .

[0027] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the cross section of the inclined mounting platform 10 is a right-angled trapezoid, and the thermal infrared sensor 11 is embedded on the inclined surface of the right-angled trapezoid.

[0028] In this embodiment, the thermal infrared sensor 11 on the right-angle trapezoidal slope can be used to laser clean the outer side of the gun head body 1 and perform infrared thermal sensing detection after a certain angle range.
