Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings. In the drawings, the same reference numerals are given to constituent parts having substantially the same or similar structures and functions, and repeated description thereof will be omitted.
Fig. 1 is a schematic external view of an embodiment of a dual-window laser output head 100 of the present invention, which includes a housing 110; an input port 190; a first output window 120 located at the front end of the housing 110; a second output window 130 at a side of the housing 110; and a positioning member 160. The positioning member 160 is disposed in the housing 100 and extends onto the housing 110 to be coupled to the first reflecting mirror 140 (not shown in fig. 1) inside the housing 110 to control the position of the first reflecting mirror.
According to one embodiment, the positioning member 160 may be a mechanical or electrical component, or a combination of both, that extends into the housing 100, and the portion of the housing may be a button or operating handle, or other form.
According to one embodiment, the laser output stud 100 further includes a link 170, which may include an optical fiber, that enters the laser output stud 100 through the input port 190 to input a laser beam generated by a laser source into the interior of the housing 110 of the laser output stud 100.
According to one embodiment, the wiring 170 may also include electrical wires to provide the necessary power to the laser output head.
According to one embodiment, when the positioning member 160 controls the first reflecting mirror 140 to be located at the first position, the laser beam introduced through the line 170 is output from the first output window 120, and when the positioning member controls the first reflecting mirror 140 to be located at the second position, the laser beam introduced through the line 170 is output from the second output window 130.
In one embodiment, the first output window 120 is perpendicular to the longitudinal direction of the laser output head (i.e., the long axis of the laser output head), and the second output window 130 is parallel to the longitudinal direction of the laser output head.
According to one embodiment, the laser output head 100 may also include a laser emitter 180 (not shown in FIG. 1). The laser emitter 180 is used to direct the laser beam introduced by the connecting line 170 further and to emit the laser beam straight along the long axis of the laser output head 100 for better focusing on the surface of the device to be cleaned. The light emitting direction of the laser transmitter 180 is consistent with the long axis direction of the laser output head. Laser light directed into housing 110 through the optical fibers in connection 170 is first directed to laser emitter 180 and then emitted by laser emitter 180 to either impinge directly on an output window or be reflected to an output window. According to one embodiment, the laser transmitter 180 includes a laser collimator and a galvanometer.
Fig. 2 is a schematic diagram of the internal structure of an embodiment of the laser output head 100 of the present invention. The positioning member 160 may position the first mirror 140 in a first position (shown by a solid line) or a second position (shown by a dotted line). The structure of the positioning member 160 and its position on the housing can be designed according to different applications, and the positioning member 160 can be a mechanical component, an electric component, or a combination of the two. The position of the positioning member 160 on the housing 110 in fig. 2 is only an example, and it does not limit the position of the positioning member 160 on the housing 110.
When the first mirror 140 is in the first position, the laser beam emitted from the laser emitter 180 is emitted directly from the first output window 120. When the first reflecting mirror 140 is located at the second position, the laser beam emitted from the laser emitter is directed to the first reflecting mirror 140, reflected, and then emitted from the second output window. The dashed line with arrows in fig. 2 is an illustration of the path taken by the laser beam.
As can be seen from fig. 2, the first position is not between the laser emitter 180 and the first output window, and the laser beam emitted by the laser emitter 180 may be directed towards the first output window without obstruction. The second position is located between the laser emitter 180 and the first output window, and when the first reflector is located at the second position, the first reflector completely covers the position of the first output window, and the laser beam emitted by the laser emitter 180 is reflected and then emitted from the second output window.
In the embodiment of fig. 2, the positioning member 160 may control the first mirror 140 to move in a direction transverse to the laser output head 100. When the positioning member 160 positions the first reflecting mirror 140 at the first position in the drawing, the first reflecting mirror 140 does not block the laser beam, and the laser beam is output from the first output window 120, and when the positioning member 160 positions the first reflecting mirror 140 at the second position in the drawing, the first reflecting mirror 140 is between the laser emitter 180 and the first output window 120, and the laser beam is output from the second output window 130 after being reflected by the first reflecting mirror 140. Fig. 2 does not show the configuration of the positioning member 160, which may be any feasible manner, and the present invention is not limited thereto.
However, in some applications, due to the small space for operation, the laser output head 100 is required to be elongated in the longitudinal direction of the laser output head. Therefore, the first reflecting mirror 140 cannot move in the lateral direction of the laser output head. Therefore, it is possible to design the first reflecting mirror 140 to be rotatable along one axis, or it is possible to design the first reflecting mirror 140 to be movable only in the longitudinal direction of the laser output head.
Fig. 3 is another embodiment of the present invention. In this embodiment, the positioning member 160 may control the first mirror 140 to rotate along an axis a that is perpendicular to both the lateral and longitudinal directions of the laser output head 100. Fig. 3 does not show the configuration of the positioning member 160, which may be any feasible manner, and the present invention is not limited thereto.
When the positioning member 160 positions the first reflecting mirror 140 at the first position, the first reflecting mirror 140 avoids a propagation path of the laser beam emitted from the laser emitter 180, and the laser beam is directly emitted to the first output window 120. When the positioning member 160 rotates the first reflecting mirror 140 to the second position, the first reflecting mirror 140 reflects the laser beam emitted from the laser emitter 180 to emit the laser beam to the second output window 130.
It is also contemplated that the first mirror 140 may be movable only in the longitudinal direction of the laser delivery head, and for this purpose, the laser delivery head 100 further includes a second mirror. The positioning member 160 may position the first reflecting mirror 140 such that the laser beam introduced into the laser output head 100 through the connection line 170 may be emitted from the first output window 120 or the second output window 130 after being reflected by the first reflecting mirror and/or the second reflecting mirror.
Fig. 4 is a schematic diagram of the internal structure of one embodiment of the laser output head 100 of the present invention. This embodiment includes a second mirror 150, which is also within housing 110. The first reflecting mirror 140 may be moved in the longitudinal direction of the laser output head 100 by the positioning member 160. Fig. 4 does not show the configuration of the positioning member 160, which may be any feasible manner, and the present invention is not limited thereto.
According to one embodiment, second mirror 150 is fixed in position. The laser beam emitted from laser emitter 180 is directed to second mirror 150, and reflected and directed to second output window 130.
The positioning member 160 may control the first reflecting mirror 140 to move in the longitudinal direction of the laser output head within the housing. When the positioning member 160 positions the first mirror 140 at the first position, the laser beam reflected by the second mirror 150 is reflected by the first mirror and directed to the first output window 120. When the positioning member 160 positions the first reflecting mirror 140 at the second position, the laser beam reflected by the second reflecting mirror 150 is directly emitted to the second output window 130 and then emitted from the second output window 130.
As can be seen from fig. 4, the first position is located between the second mirror and the second output window, and when the first mirror 140 is located at the first position, the laser beam emitted from the laser emitter 180 is reflected by the second mirror 150 and directed to the second output window, but is reflected by the first mirror 140 located at the first position and finally directed to the first output window 120. The second position is not between the second mirror and the second output window, and when the first mirror 140 is in the second position, the laser beam emitted from the laser emitter 180 is reflected by the second mirror 150, directed to the second output window 130 without being blocked, and then emitted from the second output window 130.
In various embodiments, the laser transmitter 180 includes a laser beam collimator and a galvanometer such that the laser beam input through the connection line 170 passes through the laser collimator and the galvanometer in sequence and is directed to the first mirror or the second mirror.
In various embodiments, first mirror 140 and second mirror 150 are parallel to each other.
According to the utility model discloses a design theory design's laser output head is simple in structure, moreover, because the side also has laser beam output window for the laser beam can be followed the vertical or horizontal output of laser output head, consequently, to operating space's strong adaptability, can extensively adapt to the surface cleaning of various equipment.
For example, when the laser beam clearance is implemented to the surface attachment of different positions in needs narrow and small space, and because the space is narrow and small, when the laser output head can not change position, the utility model discloses a laser output head can implement effective clearance.
For another example, if there is an unremovable member that obstructs the laser beam cleaning operation on the front and side surfaces of the surface to be processed, since the laser output head of the present invention has more than one laser beam output window, the laser beam output direction can be selectively changed, and thus effective cleaning can be performed.
Fig. 5 is an application scenario of an embodiment of the present invention. The surface of the device to be cleaned has a groove, and the longitudinal direction of the laser output head 100 cannot be changed after the laser output head extends into the groove due to the narrow space of the groove. If the laser output head 100 had only the first output window 120 at the front end, or only the second output window 130 at the side, then the entire concave surface would not be cleaned effectively. And the utility model discloses can select to export the laser beam from the front end or the side of laser output head, just can solve this problem well.
The utility model also provides a laser surface descaling machine, include: the host comprises a power supply and a laser source; and a laser output head 100; the host is connected to the laser output head 100 through a connection 170, the connection 170 may include an optical fiber, and the host may input a laser beam to the laser output head through the optical fiber in the connection 170. The wiring 170 may also include wires through which the host computer may provide the required power to the laser delivery head 100.
Fig. 6 shows an embodiment of the laser surface cleaning machine of the present invention, which includes a host and a laser output head. The wiring 170 includes optical fibers and electrical wires and is input into the laser output head through an input port 190 of the laser output head.
According to one embodiment, the laser output head may have two input ports, and the optical fiber and the electrical wire in the connection wire 170 may respectively enter the interior of the laser output head through different input ports.
