Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] See also Figure 1, the laser processing device 10 provided in the embodiment of the present application is now described. The laser processing device 10 provided in the embodiment of the present application includes a base 11, a laser processing mechanism 12 and a fixture 13. The laser processing mechanism 12 is arranged on the base 11. The laser head 121 of the laser processing mechanism 12 can be rotatably arranged. Rotating the laser head 121 can adjust the laser processing angle; the fixture 13 includes a clamping member 131, a carrier 132 and a flip table 133. The carrier 132 is arranged on the base 11. The carrier 132 and the laser processing mechanism 12 can be relatively movably arranged. The flip table 133 can be rotatably arranged on the carrier 132, and the clamping member 131 can be rotatably arranged on the flip table 133; the clamping member 131 clamps one end of the workpiece and drives the workpiece to rotate along the rotation axis of the clamping member 131, and the flip table 133 can drive the clamping member 131 and the workpiece to rotate synchronously along the rotation axis of the flip table 133; rotating the flip table 133 and / or rotating the laser head 121 can adjust the angle between the light beam emitted by the laser head 121 and the rotation axis of the clamping member 131.

[0033] In the laser processing device 10 scheme provided in the embodiment of the present application, the laser processing mechanism 12 and the fixture 13 cooperate to operate. The fixture 13 is used to fix the workpiece to the target angle and position, and the laser processing mechanism 12 processes the workpiece by correspondingly controlling the laser head 121, wherein the fixture 13 and the laser processing mechanism 12 are relatively movable and adjustable. The specific relative movement adjustment setting method is not limited. For example, the position of the laser processing mechanism 12 can be kept fixed while the fixture 13 moves along the three-dimensional space direction, or the position of the laser processing mechanism 12 can be moved along one direction of the three-dimensional space while the fixture 13 moves along the remaining directions of the three-dimensional space. It can also be other matching movement settings that meet the conditions, without limitation. The structural setting relationship between the laser processing mechanism 12 and the carrier 132 and the base 11 can be directly connected or indirectly connected using an intermediate piece.

[0034] Among them, the clamping member 131 of the fixture 13 is used to clamp and fix the workpiece, and the rotation of the clamping member 131 relative to the flip table 133 can be used to synchronously adjust the corresponding angle of the workpiece, and the rotation of the flip table 133 relative to the carrier 132 can be used to synchronously adjust the corresponding angle of the clamping member 131 and the workpiece, and the relative movement of the carrier 132 and the laser processing mechanism 12 in the three-dimensional space direction can adjust the relative position of the laser head 121 and the workpiece. If the carrier 132 moves relative to the laser processing mechanism 12, it can be understood that the flip table 133 and the clamping member 131 move synchronously relative to the laser head 121 of the laser processing mechanism 12, that is, the workpiece fixed by the clamping member 131 also moves synchronously relative to the laser head 121 of the laser processing mechanism 12, and the movement of the laser processing mechanism 12 relative to the carrier 132 can be understood as the laser head 121 moves synchronously relative to the carrier 132, that is, the laser head 121 moves relative to the workpiece fixed by the clamping member 131, so as to realize the processing positioning in the three-dimensional space direction.

[0035] Further, regarding the rotation setting scheme between the flip table 133 and the laser head 121, rotating the flip table 133 and / or rotating the laser head 121 can adjust the angle between the light beam emitted by the laser head 121 and the rotating shaft of the clamp 131. It can be understood that adjusting the rotation of any one of the flip table 133 and the laser head 121 can change the angle between the laser head 121 and the clamp 131, that is, it can be used to adjust the angle between the workpiece and the laser head 121, so as to adjust the angle of the workpiece processed by the laser head 121. Among them, rotating the flip table 133 can directly adjust the inclination angle of the workpiece, which is used to adjust the positioning of the workpiece and realize multiple angle positioning, while rotating the laser head 121 can directly adjust the light output angle of the laser, which is used to adjust the processing direction, and can realize multi-angle processing, thereby improving the processing performance of complex trajectories. In the embodiment of the present application, the rotation setting of the flip table 133 and the laser head 121 is defined as follows: rotating either the flip table 133 or the laser head 121 alone can adjust the angle between the laser head 121 and the workpiece fixed by the clamp 131, so that when the angle of the workpiece is fixed, the angle of the laser head 121 relative to the workpiece can be adjusted to achieve corresponding processing at different angles. On the basis of the adjustment and positioning of the tilt angle of the workpiece, combined with the rotation adjustment of the clamp 131 relative to the flip table 133, the rotation of the workpiece can be controlled so that the laser head 121 processes different sides of the workpiece. In this way, the laser processing device 10 of the embodiment of the present application can process different sides of the workpiece under various angles, so as to process the trajectory to be processed with a relatively complex angle of the workpiece.

[0036] It should be noted that the clamping member 131 in the embodiment of the present application is used as an example to clamp and fix the workpiece. Of course, it can also be other settings that can fix the workpiece, such as threaded fixing, press fixing, snap fixing, etc. The clamping member 131 is only a preferred embodiment of the present application and is not used to limit the present application. Any fixing method that can load and unload the workpiece is acceptable. In addition, regarding the rotating shaft of the laser head 121, the rotating shaft of the flip table 133, and the rotating shaft of the clamping member 131 in the embodiment of the present application, each rotating shaft is not a physical description, but can be understood as the central axis of rotation, which is the meaning in the following embodiments.

[0037] In the above embodiment, the clamp 13 may also include a first driving member 134 and a second driving member 135. The first driving member 134 is fixedly arranged relative to the carrier 132, and the first driving member 134 is drivingly connected to the flip table 133, and the first driving member 134 drives the flip table 133 to rotate; the second driving member 135 is arranged on the flip table 133, and the second driving member 135 is drivingly connected to the clamping member 131, and the second driving member 135 drives the clamping member 131 to rotate.

[0038] The first driving member 134 is controlled to drive the turning table 133 to rotate, so that the clamping member 131 and the workpiece fixed by the clamping member 131 rotate synchronously to control and adjust the inclination angle of the workpiece relative to the laser head 121; the second driving member 135 is controlled to drive the clamping member 131 to rotate, so that the workpiece fixed by the clamping member 131 rotates synchronously to control and adjust different sides of the workpiece relative to the laser head 121.

[0039] The first driving member 134 and the second driving member 135 can be automatic driving members or manual driving members. Of course, one can be an automatic driving member and the other can be a manual driving member according to the needs. It can be determined according to the specific implementation needs and is not limited. The fixed arrangement of the first driving member 134 relative to the carrier 132 can be understood as follows: during the structural installation process, the first driving member 134 and the carrier 132 can be relatively movable and adjustable, and when the first driving member 134 and the flip table 133 are driven and connected, the first driving member 134 and the carrier 132 are in a relatively fixed state; similarly, when the second driving member 135 is arranged on the flip table 133, when the second driving member 135 and the clamping member 131 are driven and connected, the second driving member 135 and the flip table 133 are in a relatively fixed state.

[0040] In the above embodiment, the rotation angle range of the flip table 133 is set to 90°; when the flip table 133 rotates to one end of the corresponding angle range, the rotation axis of the clamp 131 is in the horizontal direction; when the flip table 133 rotates to the other end of the corresponding angle range, the rotation axis of the clamp 131 is in the vertical direction. This embodiment takes the angular range of the rotation angle of the flip table 133 as an example of setting it to 90°. In the specific angular range setting of 90°, the state of the workpiece is switched between vertical and horizontal. In this way, the flip table 133 is controlled to rotate, and the workpiece can be adjusted from the horizontal state to the vertical state and any angle of inclination during the process. Combined with the rotatable setting of the clamp 131, laser processing can be completed at any position on the surface of the workpiece. In actual production, the trajectory of the workpiece to be processed is generally relatively regular, and the corresponding workpiece positioning state is mainly horizontal and vertical positioning. Therefore, in this embodiment, the rotation angle limit of the turning table 133 is set to 90°, and the turning axis of the clamping member 131 corresponding to the two limit ends of the turning table 133 corresponds to the horizontal direction and the vertical direction respectively, which helps to ensure the horizontal positioning accuracy and vertical positioning accuracy of the workpiece respectively. Among them, a limit structure for limiting the turning table 133 from rotating beyond the limit can be set on the carrier 132. When the turning table 133 rotates to the angle limit position, the limit structure can prevent the turning table 133 from continuing to rotate.

[0041] Of course, in the embodiment of the present application, the fixture 13 may also include a measuring component 139 for measuring the rotation angle of the flip table 133. Taking the measuring component 139 as an example, the measuring component 139 includes a pointer 1392 and a ruler 1391 for measuring the angle, the measurement is set on the carrier 132, and the pointer 1392 is relatively fixed to the flip table 133. The measurement and pointer 1392 can be set in degrees corresponding to each other, so as to accurately control the rotation angle of the flip table 133.

[0042] See also Figure 1 In one embodiment, the clamp 13 may further include a first pressing assembly 136 and a second pressing assembly 137, the first pressing assembly 136 includes a first mounting frame 1361 and a first pressing piece 1362, the first mounting frame 1361 is fixedly arranged relative to the carrier 132, and the first pressing piece 1362 is movably arranged on the first mounting frame 1361 along the vertical direction, and when the flip table 133 is rotated to make the rotating axis of the clamping piece 131 along the vertical direction, the first pressing piece 1362 is opposite to the clamping piece 131 along the vertical direction; the second pressing assembly 137 includes a second mounting frame 1371 and a second pressing piece 1372, the second mounting frame 1371 is fixedly arranged relative to the carrier 132, and the second pressing piece 1372 is movably arranged on the second mounting frame 1371 along the horizontal direction; when the flip table 133 is rotated to make the rotating axis of the clamping piece 131 along the horizontal direction, the second pressing piece 1372 is opposite to the clamping piece 131 along the horizontal direction.

[0043] The first pressing component 136 in this embodiment is used to cooperate with the two ends of the workpiece of the clamping member 131 in the vertical direction. The corresponding use state is that the flip table 133 is flipped so that the rotating axis of the clamping member 131 is along the vertical direction. Taking the first pressing member 1362 being set vertically above the flip table 133 as an example, at this time, the lower end of the workpiece in the vertical direction is fixed by the clamping member 131, and the vertical upper end of the workpiece is pressed downward by the first pressing member 1362. Of course, the first pressing member 1362 can also be set with a structure that limits the workpiece in the horizontal direction to improve the positioning stability of the workpiece. Similarly, the second pressing assembly 137 is used to cooperate with the clamping member 131 to fix the two ends of the workpiece in the horizontal direction. The corresponding usage state is that the flip table 133 is flipped so that the rotating axis of the clamping member 131 is in the horizontal direction. At this time, one end of the workpiece in the horizontal direction is fixed by the clamping member 131, and the other end of the workpiece in the horizontal direction is pressed toward the clamping member 131 by the second pressing member 1372. Of course, the second pressing member 1372 can also be set with a structure that limits the workpiece in the vertical direction to improve the positioning stability of the workpiece.

[0044] It should be noted that the structure of the fixture 13 in this embodiment is used to position the workpiece to be processed horizontally and the workpiece to be processed vertically. The structure of the first pressing member 1362 is used to press the workpiece in the vertical direction to position it, and it must not affect the rotation of the workpiece with the clamping member 131. Similarly, the structure of the second pressing member 1372 is used to press the workpiece in the horizontal direction to position it, and it must not affect the rotation of the workpiece with the clamping member 131. Among them, the first pressing member 1362 and the second pressing member 1372 can be manually driven and controlled, or automatically driven and controlled, without limitation.

[0045] See also Figure 2 In another embodiment, the clamp 13 may further include a third pressing assembly 138, the third pressing assembly 138 includes a third mounting frame 1381 and a third pressing piece 1382, the third mounting frame 1381 is connected to the flip table 133 or the clamping piece 131, the third pressing piece 1382 and the axis of the clamping piece 131 are movably set on the third mounting frame 1381, and the third pressing piece 1382 and the clamping piece 131 are relatively set along the axis of the clamping piece 131.

[0046] The third mounting frame 1381 is connected to the flip table 133 or the clamping member 131, and it can be understood that the third mounting frame 1381 rotates synchronously with the rotation of the flip table 133, that is, the clamping member 131 and the third pressing member 1382 are always arranged relative to each other along the rotation axis of the clamping member 131, so that the third pressing member 1382 can always cooperate with the clamping member 131, so as to realize the positioning of the workpiece at different inclination angles, of course, including the positioning of the workpiece when it is placed horizontally and when it is placed vertically. Therefore, the structural setting of the fixture 13 in this embodiment can be used to position the workpiece at any angle corresponding to the rotation angle limit of the flip table 133.

[0047] See also Figure 1 and Figure 3 Further, the first pressing member 1362 in the above embodiment may include a connecting portion 13621, a limiting portion 13622 and a pressing portion 13623, the connecting portion 13621 is movably connected to the first mounting frame 1361 along the vertical direction, the limiting portion 13622 is arranged on the side of the connecting portion 13621 close to the clamping member 131, and the limiting portion 13622 can be limitedly arranged along the horizontal direction to limit the horizontal direction of the workpiece to be processed; the pressing portion 13623 is arranged on the connecting portion 13621 along the vertical direction, the pressing portion 13623 protrudes from the connecting portion 13621 toward the side close to the clamping member 131, and the pressing portion 13623 presses on the vertical upper end of the workpiece to be processed.

[0048] The pressing portion 13623 is a pressing structure of the first pressing member 1362, and the connecting portion 13621 serves as an intermediate member connecting the pressing portion 13623 and the limiting portion 13622 to the first mounting frame 1361 respectively. During the movement of the connecting portion 13621 in the vertical direction, the pressing portion 13623 and the limiting portion 13622 are synchronized in the vertical direction, wherein the pressing portion 13623 is used to press on the vertical upper end of the workpiece in the vertical direction to cooperate with the clamping member 131 to position the workpiece in the vertical direction. The pressing portion 13623 of this embodiment takes a rod-shaped structure that is arranged in the vertical direction and coaxially with the rotation center axis of the clamping member 131 as an example. In this way, when the lower end of the pressing portion 13623 is pressed and abutted against the upper end of the workpiece, it can help the clamping member 131 to control the workpiece. The limiting portion 13622 is used to limit the workpiece in the horizontal direction to ensure that the workpiece is accurately positioned in the vertical direction. The limiting portion 13622 is configured to protrude downward from the connecting portion 13621 as an example. The limiting portion 13622 can be a raised wall that is closed at both ends and surrounds the pressing portion 13623, or it can be a plurality of raised structures that surround the pressing portion 13623 at intervals. The limiting portion 13622 abuts against the radial side of the workpiece to play a limiting role.

[0049] Of course, the pressing portion 13623 and the connecting portion 13621 can be detachably connected or can be an integral structure. Similarly, the limiting portion 13622 and the connecting portion 13621 can be detachably connected or can be an integral structure. Alternatively, the pressing portion 13623 can be movably adjusted along the vertical direction on the connecting portion 13621, and the limiting portion 13622 can be movably adjusted along the horizontal direction on the connecting portion 13621, so as to be suitable for workpieces of different sizes.

[0050] See also Figure 1 , Figure 3 and Figure 4 Further, the first pressing member 1362 of the above embodiment may further include an air guide portion 13624, the air guide portion 13624 is arranged on the side of the connecting portion 13621 close to the clamping member 131, the air guide portion 13624 is arranged between the pressing portion 13623 and the limiting portion 13622, and the pressing portion 13623 protrudes from the air guide portion 13624 toward the side close to the clamping member 131; the connecting portion 13621 is provided with a first air channel 136211, and the air guide portion 13624 is provided with a second air channel 136212. The connecting portion 13621 is provided with a through hole 136212, and the spacing area between the pressing portion 13623 and the limiting portion 13622 is connected to the laser head 121 via the through hole 136212.

[0051] In this embodiment, the first pressing member 1362 is used to press and position the workpiece, and the trajectory to be processed of the workpiece is located at the vertical upper end of the workpiece, that is, the pressing end side of the pressing portion 13623. The specific trajectory to be processed is located at the radial edge of the workpiece. The first air channel 136211 of the connecting portion 13621 and the second air channel 136241 of the air guide portion 13624 can be understood as channels opened inside the structure and passing through the corresponding structure. The air guide portion 13624 is set between the pressing portion 13623 and the limiting portion 13622, and the vertical lower end of the pressing portion 13623 protrudes from the air guide portion 13624. It can be understood that the air guide portion 13624 will not interfere with the workpiece, the pressing portion 13623 and the limiting portion 13622, respectively, and the protective gas required during laser processing will not interfere with each other. The shielding gas is connected to the first air channel 136211 of the connecting part 13621 through the first air channel 136211, and the shielding gas is passed to the second air channel 136241 in the air guide part 13624, thereby releasing the shielding gas to the upper end side of the workpiece. The interval area between the pressing part 13623 and the limiting part 13622 is connected to the laser head 121 through the through hole 136212, which can be understood as spatial connection, that is, the laser emitted by the laser head 121 passes through the through hole 136212 on the connecting part 13621 and is emitted to the upper end of the workpiece for processing.

[0052] Among them, the opening of the second air channel 136241 connected to the opening of the first air channel 136211 is defined as the air inlet, and the other end opening of the second air channel 136241 is defined as the air outlet, which is arranged on the side of the air guide part 13624 close to the clamping member 131. Multiple air outlets can be set, and the axial directions corresponding to the air outlets can also be set in different directions.

[0053] Furthermore, in the above embodiment, the rotation axis of the laser head 121 is parallel to the rotation axis of the flip table 133 , and the rotation axis of the clamping member 131 is perpendicular to the rotation axis of the flip table 133 .

[0054] According to the principle of determining a plane by two intersecting straight lines, when the rotating axis of the clamping member 131 is perpendicular to the rotating axis of the flip table 133, the rotating axis of the laser head 121 is parallel to the rotating axis of the flip table 133. The angle value of rotating the laser head 121 is the angle change value of the laser head 121 relative to the flip table 133, so that the angle between the laser head 121 and the flip table 133 is more efficient. The definition of the relationship that the rotating axis of the clamping member 131 is perpendicular to the rotating axis of the flip table 133 and the rotating axis of the laser head 121 is parallel to the rotating axis of the flip table 133 in this embodiment can not only meet the function of being able to process the trajectory to be processed with a relatively complex angle of the workpiece, but also facilitate programmed automatic control.

[0055] Of course, the rotating axis of the clamping member 131 and the rotating axis of the flip table 133 can also be set to other angle relationships, that is, non-perpendicular relationships, and the rotating axis of the laser head 121 and the rotating axis of the flip table 133 can also be set to other angle relationships, that is, non-parallel relationships, as long as the conditions of the processing trajectory with more complex angles of the workpiece can be met.

[0056] See also Figure 1 Specifically, a first direction, a second direction and a third direction that are perpendicular to each other are defined, the first direction and the second direction are set to horizontal directions, and the third direction is set to vertical direction, wherein the first direction is denoted as X, the second direction is denoted as Y, and the third direction is denoted as Z.

[0057] The laser processing device 10 in the above embodiment may further include a support frame 14, the support frame 14 is arranged on the base 11, the laser processing mechanism 12 is movably arranged on the support frame 14 along the first direction, and the support frame 14 may be a gantry structure, so that the laser head 121 is suspended so as to be flexibly adjusted for processing. The laser head 121 is movably arranged along the third direction relative to the support frame 14, the laser head 121 is rotatable relative to the support frame 14, the rotation axis of the laser head 121 and the rotation axis of the flip table 133 are parallel to the second direction, and the rotation axis of the clamping member 131 is perpendicular to the second direction; the laser processing device 10 may further include a bearing platform 15, the bearing platform 15 is movably arranged on the base 11 along the second direction, and the carrier 132, the first mounting frame 1361, the first driving member 134 and the second mounting frame 1371 are arranged on the bearing platform 15.

[0058] The carrier 132 and the laser head 121 of the laser processing mechanism 12 can be relatively moved in three-dimensional space. The implementation of this application takes the movement of the carrier 15 carrying the fixture 13 along the second direction as an example, and the movement of the laser head 121 in the first and third directions is used as an example. Compared with the structural volume and weight of the fixture 13, the laser head 121 is lighter in structure. Therefore, controlling the laser head 121 along the first and third directions can achieve higher-precision movement and positioning, and the movement of the platform along the second direction can be assisted by structures such as guide rails, and high-precision movement and positioning can also be achieved in a single direction.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
