[0044] Please refer to Figure 1 The beam adjusting device of the laser of the embodiment of the present application can be connected with the laser and used for adjusting the light emitting angle of the laser 10. Wherein, along the light emitting direction of the laser 10, the laser 10 includes a first part and a second part.

[0045] For the convenience of description, the light emitting direction of the laser 10 is defined as the front-back direction, and the laser emitting end of the laser 10 is defined as front, and vice versa. Therefore, the first part of the laser 10 is in front, and the second part is in back. And each direction on the plane perpendicular to the front-back direction is defined as the up, down, left and right direction.

[0046] Referring toFigure 1 and Figure 2 As shown, the beam adjustment device 100 includes a positioning seat 110 and an adjustment seat 120. The positioning seat 110 is provided with a first receiving cavity for accommodating the first part of the laser 10. The positioning seat 110 is used to position the first part of the laser 10 in the front and back positions in the light output direction.

[0047] Specifically, such as Figure 2 As shown, in some embodiments, the positioning base 110 includes a first base 111 and a positioning member 114. The positioning member 114 is connected to the first base 111 and can rotate relative to the first base 111. The positioning member 114 can act on a first part of the laser 10 to enable the first part of the laser 10 to rotate. The positioning member 114 can be a positioning connection structure such as a screw or pin, and can be detachably connected to the first base 111. For example, the first base 111 may be provided with a positioning hole. The positioning member 114 can pass through the positioning hole, thereby enabling the positioning member 114 to be rotatably connected to the first base 111.

[0048] like Figure 2 As shown, the positioning member 114 can be connected to the first part of the laser 10. The positioning member 114 not only enables the first part of the laser 10 to rotate on the first base 111, but also fixes the position of the first part of the laser 10 in the front-back direction relative to the first base 111.

[0049] See Figure 2 In some embodiments, the first base 111 includes a first sub-base 112 and a second sub-base 113 that are perpendicularly connected to each other. Two positioning members 114 are rotatably connected to the first sub-base 112 and the second sub-base 113, respectively. The two positioning members 114 are respectively connected to a first portion of the laser 10, enabling the first portion of the laser 10 to rotate about a first axis and a second axis, respectively, with the first axis and the second axis extending along a first direction and a second direction, respectively.

[0050] like Figure 2As shown, the first direction and the second direction can be the up-down direction and the left-right direction respectively. One of the two positioning members 114 is connected to the first sub-base body 112 along the up-down direction and can rotate relative to the first sub-base body 112 around the first axis. The other positioning member 114 is connected to the second sub-base body 113 along the left-right direction and can rotate relative to the second sub-base body 113 around the second axis. Thus, when the two positioning members 114 are connected to the first part of the laser 10 respectively, the first part of the laser 10 can rotate around the first axis and the second axis respectively. Meanwhile, the two positioning members 114 can fix the position of the first part of the laser 10 in the front-back direction relative to the first base body 111, and the two positioning members 114 can also act as fulcrums to adjust the angles of the laser 10 in the up-down direction and the left-right direction.

[0051] As shown in Figure 2 The first base body 111 can be roughly in the shape of an L-shaped block structure, with the first sub-base body 112 extending along the up-down direction and the second sub-base body 113 extending along the left-right direction. The first base body 111 can roughly form a fan-shaped accommodating space, which is the first accommodating cavity for accommodating the first part of the laser 10. Thus, the first part of the laser 10 can be accommodated in the first accommodating cavity and rotatably arranged on the first base body 111 through the two positioning members 114.

[0052] In the embodiment of the application, the positioning seat 110 fixes the position of the first part of the laser 10 in the front-back direction, i.e., the positioning seat 110 can fix the position of the laser 10 as a whole in the front-back direction. Moreover, the positioning seat 110 can enable the first part of the laser 10 to rotate around the first axis and the second axis respectively, so that the position of the second part of the laser 10 in the up-down direction and the left-right direction can be moved and act as a fulcrum.

[0053] As shown in Figure 1 and Figure 2 In the embodiment of the application, the adjusting seat 120 is used to change the position of the second part of the laser 10 in the up-down direction and the left-right direction, so as to adjust the emission angle of the laser 10. Specifically, the adjusting seat 120 comprises a second base body 121 and a first adjusting member 122. The second base body 121 is provided with a second accommodating cavity for accommodating the second part of the laser 10. The first adjusting member 122 is arranged on the second base body 121 and can move relative to the second base body 121 along the first direction, which is perpendicular to the front-back direction. The first adjusting member 122 abuts against the second part of the laser 10 to move the second part in the first direction and adjust the emission angle of the laser 10.

[0054] The first direction can be a vertical direction. When the first adjusting member 122 moves along the vertical direction, the second part of the laser 10 can be driven to move along the vertical direction, so that the emission angle of the laser 10 can be adjusted along the vertical direction.

[0055] The first adjusting member 122 can be a connecting structure such as a screw or a screw rod, which can be detachably connected to the second seat body 121 and can rotate relative to the second seat body 121 about the axis of the first adjusting member 122. The axis of the first adjusting member 122 can extend along the first direction. Therefore, when the first adjusting member 122 rotates relative to the second seat body 121 about the axis of the first adjusting member 122, the first adjusting member 122 can move relative to the second seat body along the first direction.

[0056] Referring to Figure 2 As shown, the adjusting seat 120 includes a second adjusting member 123, which is arranged on the second seat body 121 and can move relative to the second seat body 121 along a second direction perpendicular to the front-rear direction and the first direction. The second adjusting member 123 abuts against the second part of the laser 10 to move the second part along the second direction.

[0057] The second direction can be a left-right direction. When the second adjusting member 123 moves along the left-right direction, the second part of the laser 10 can be driven to move along the left-right direction, so that the emission angle of the laser 10 can be adjusted along the left-right direction.

[0058] The second adjusting member 123 can be a connecting structure such as a screw or a screw rod, which can be detachably connected to the second seat body 121 and can rotate relative to the second seat body 121 about the axis of the second adjusting member 123. The axis of the second adjusting member 123 can extend along the second direction. Therefore, when the second adjusting member 123 rotates relative to the second seat body 121 about the axis of the second adjusting member 123, the second adjusting member 123 can move relative to the second seat body along the second direction.

[0059] In the embodiments of the present application, when it is necessary to adjust the laser emission angle of the laser 10, the first adjusting member 122 and the second adjusting member 123 are combined to drive the second part of the laser 10 to move along the first direction and the second direction, so that the laser 10 can be adjusted along the first direction and the second direction. Figure 3 As shown, the first adjusting member 122 can drive the second part of the laser 10 to move along the vertical direction, and the first part of the laser 10 can rotate about the positioning member 114 extending along the left-right direction, so that the laser 10 as a whole can swing up and down, and the laser emission angle of the laser 10 can be adjusted up and down. Also as shown, Figure 4As shown, the second part of the laser 10 can be moved along the left-right direction by the second adjusting member 123, and the first part of the laser 10 can be rotated around the positioning member 114 extending along the up-down direction, so that the laser 10 as a whole can swing left and right, and the laser exit angle of the laser 10 can be adjusted left and right. Therefore, the exit angle of the laser 10 can be adjusted by the light beam adjusting device 100, the deviation of the laser beam from the laser body is reduced, the light collimation of the laser 10 is improved, the effect of laser processing is improved, and the laser processing requirements of users for processing more materials and different volume workpieces are met.

[0060] Referring to Figure 2 As shown, in some embodiments, the second seat body 121 is annular, and the second seat body 121 can form a substantially annular accommodating space, which is a second accommodating cavity for accommodating the second part of the laser 10.

[0061] As Figure 2 As shown, the second part of the laser 10 is arranged in the annular space of the second seat body 121. The number of the first adjusting members 122 is two, and the two first adjusting members 122 are arranged on the two sides of the second seat body 121 along the first direction. It can be understood that the two first adjusting members 122 can be connected with the second part of the laser 10, so that the two first adjusting members 122 can drive the second part of the laser 10 to move along the first direction (i.e. the up-down direction), so as to adjust the up-down angle of the laser exit of the laser 10.

[0062] The number of the second adjusting members 123 is two, and the two second adjusting members 123 are arranged on the two sides of the second seat body 121 along the second direction. It can be understood that the two second adjusting members 123 can be connected with the second part of the laser 10, so that the two second adjusting members 123 can drive the second part of the laser 10 to move along the second direction (i.e. the left-right direction), so as to adjust the left-right angle of the laser exit of the laser 10.

[0063] It should be noted that in each embodiment of the present application, the first direction and the second direction are respectively the up-down direction and the left-right direction in the orientation shown. Figure 1 The adjustment mode of the light beam adjusting device 100 is described in detail taking the up-down direction and the left-right direction in the orientation shown as an example. It can be understood that the first direction can not be the up-down direction, and the second direction can not be the left-right direction, as long as the first direction and the second direction are perpendicular to the front-rear direction, and the second part of the laser 10 can move in the plane perpendicular to the front-rear direction.

[0064] Referring to Figure 5As shown, in some embodiments of this application, the beam adjustment device 100 further includes a beam expander 130, which is connected to the first part of the laser 10 and is used to adjust the spot size of the laser beam emitted by the laser 10. The beam expander 130 may be disposed on the positioning base 110.

[0065] For example, such as Figure 5 As shown, the beam expander assembly 100 includes a first beam expander lens 131 and a second beam expander lens 132, a first lens barrel 133 for mounting the first beam expander lens 131, and a second lens barrel 134 for mounting the second beam expander lens 132. The second lens barrel 134 is connected to the light-emitting end of the first part of the laser 10. In one embodiment, the second lens barrel 134 is disposed on the positioning base 110.

[0066] The first lens barrel 133 and the second lens barrel 134 are retractably connected so that the relative distance between the first beam expander 131 and the second beam expander 132 can be adjusted, thereby adjusting the spot size of the laser beam.

[0067] In one embodiment, the first beam expander 131 can be a convex lens, and the second beam expander 132 can be a concave lens. The beam expansion factor of the laser beam can be controlled by adjusting the relative distance between the first beam expander 131 and the second beam expander 132. For example, increasing the relative distance between the first beam expander 131 and the second beam expander 132 will increase the beam expansion factor, while decreasing the relative distance between the first beam expander 131 and the second beam expander 132 will decrease the beam expansion factor, thereby allowing adjustment of the laser beam spot size.

[0068] Therefore, when it is necessary to adjust the spot size of the laser beam emitted by the laser 10, the first lens barrel 133 can be extended or retracted relative to the second lens barrel 134 in the front-to-back direction, thereby adjusting the spot size of the laser beam emitted by the laser 10. Furthermore, by adjusting the spot size of the laser beam emitted by the laser 10, the laser processing effect can be further improved, and the laser focusing needs of users for processing workpieces of various materials and sizes can be met.

[0069] In one possible embodiment of this application, such as Figure 5 As shown, the first lens barrel 133 and the second lens barrel 134 are connected at one end by threads. For example, one end of the first lens barrel 133 may be provided with an external thread, and the end of the second lens barrel 134 may be provided with an internal thread that mates with the external thread. Thus, the first lens barrel 133 and the second lens barrel 134 can be retractably connected through the engagement of the external and internal threads. This method has a simple structure and is easy to adjust the spot size.

[0070] Alternatively, in another possible embodiment of the present application, the first lens barrel 133 is slidably connected to one end of the second lens barrel 134. For example, the second lens barrel 134 can include a barrel, an adjusting gear and an adjusting knob, the first lens barrel 133 is entirely arranged in the barrel and is slidable relative to the barrel. The adjusting gear is arranged inside the barrel, and the adjusting knob is arranged outside the barrel and is fixedly connected with the adjusting gear. The first lens barrel 133 is provided with a rack outside, which is arranged along the axial direction of the first lens barrel 133. When the first lens barrel 133 is inserted into the barrel of the second lens barrel 134, the rack is engaged with the adjusting gear. When the adjusting knob is rotated to rotate the adjusting gear, the adjusting gear drives the rack to move, so that the first lens barrel 133 moves along the axial direction in the barrel, thereby realizing the telescopic connection between the first lens barrel 133 and the second lens barrel 134.

[0071] Of course, in other embodiments, other structures capable of realizing the telescopic connection between the first lens barrel 133 and the second lens barrel 134 can also be used, such as a sliding rail and a sliding groove.

[0072] The utility model also provides a kind of laser processing equipment, including laser processing head and the beam adjusting device 100 of laser 10 in any embodiment above. Laser processing head is equipped with mounting platform 200, positioning seat 110 and adjusting seat 120 are respectively installed on mounting platform 200.

[0073] For example, the first seat body 111 and the second seat body 121 can be fixedly installed on the mounting platform 200 using screws or other fasteners, and then the first part of the laser 10 is installed on the first seat body 112 through the positioning member 114, and the second part of the laser 10 is installed on the second seat body 121 through the first adjusting member 122 and the second adjusting member 123.

[0074] The above embodiments are only exemplary structures, and the structures in each embodiment are not fixedly combined. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined.

[0075] Although the utility model has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than limiting. Since the utility model can be embodied in various forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the above details, but should be interpreted broadly within the spirit and scope of the appended claims, so that all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
