The rotatable reflective component 4 is arranged on the laser light path emitted by the first laser 1 and the laser light path emitted by the second laser 2, and the rotatable reflective component 4 can rotate between the first state and the second state. The processing head 3 is arranged on the reflection light path of the rotatable reflective component 4, and is used to process a workpiece to be processed based on the laser reflected by the rotatable reflective component 4, wherein the workpiece to be processed includes a first material and a second material covered and bonded to the first material, the first material includes copper foil, etc., the second material includes a covering film, etc., and the workpiece to be processed can be a flexible printed circuit board (Full name in English: Flexible Printed Circuit, abbreviated as: FPC), etc. The control card 5 is connected to the first laser 1, the second laser 2, the processing head 3 and the rotatable reflective component 4 respectively. The control card 5 is used to control the opening and closing of the first laser 1, the second laser 2 and the processing head 3, and to control the rotation of the rotatable reflective component 4 between the first state and the second state. When the rotatable reflective component 4 is in the first state, the rotatable reflective component 4 can reflect the first laser beam to the processing head 3, and when the rotatable reflective component 4 is in the second state, the rotatable reflective component 4 can reflect the second laser beam to the processing head 3, wherein the first direction is Figure 1 The X direction in the second direction is Figure 1 in the Y direction.

[0035] In this embodiment, the pulse width of the first laser 1 is different from the pulse width of the second laser 2, so that the first laser 1 and the second laser 2 can cut different materials. For example, the first laser 1 is a picosecond laser, which is used to cut thinner materials such as plastic, glass, etc., and the second laser 2 is a nanosecond laser, which is used to cut thicker materials such as metal plates, ceramics, etc., thereby improving the applicability of the laser processing device.

The rotatable reflection component 4 is in the second state, and the laser beam emitted by the second laser 2 can be reflected to the processing head 3 through the rotatable reflection component 4. By transforming the rotatable reflection component 4 between the first state and the second state, two laser processing methods can be realized without purchasing two laser forming equipment, thereby reducing the occupied space of the laser processing device and reducing the cost.

Figure 4 This is a schematic structural diagram of a rotating table of a laser processing device provided in an embodiment of the present application from a front view. Figure 5 A schematic diagram of a structure in which a rotating table of a laser processing device provided in an embodiment of the present application is equipped with a first reflector. The rotatable reflective assembly 4 includes a rotating table 41, a first reflector 42 and a mounting bracket 43. The rotating table 41 includes a mounting seat 410, a driving member and a rotating member 411. The rotating member 411 is rotatably connected to the mounting seat 410, and the rotating member 411 is provided with a first scale line 411a and a mounting hole 411b. The first scale line 411a is distributed along the circumference of the rotating member 411 for detecting the rotation angle of the rotating member 411. The mounting bracket 43 is provided in the mounting hole 411b, and the first reflector 42 is mounted on the mounting bracket 43. The driving member is installed on the mounting seat 410, and the driving member is connected to the rotating member 411, and is used to drive the rotating member 411 to rotate, so as to drive the first reflector 42 to rotate between the first state and the second state.

[0038] In this embodiment, the driving member is a motor, and the rotating table 41 is driven by the motor. The motor drive can accurately control the speed and position of the movement, thereby improving the accuracy of the rotation angle of the rotating member 411. It can be understood that in other embodiments, the rotating table 41 can also be replaced by a rotating cylinder.

[0039] In this embodiment, the rotating table 41 also includes a worm wheel and a worm, the worm is connected to the driving member, the worm wheel is connected to the worm, and the rotating member 411 is connected to the worm wheel. When driving, the driving member drives the worm to rotate to drive the worm wheel to move, and the movement of the worm wheel drives the rotating member 411 to rotate. The rotation of the rotating member 411 drives the first reflector 42 to rotate between the first state and the second state. The worm wheel transmission structure has low noise and a certain stability, which improves the stability of the first reflector 42 rotating between the first state and the second state. It can be understood that in other embodiments, the rotating table 41 can also be driven to rotate by other transmission methods.

[0040] In this embodiment, the rotating platform 41 further includes a knob 412, which is disposed on the mounting seat 410 and connected to the rotating member 411. A second scale line 412a is provided on the outer surface of the knob 412 along the circumference of the knob 412, and the second scale line 412a is used to detect the rotation angle of the knob 412, thereby detecting the rotation angle of the rotating member 411. The knob 412 is used to fine-tune the rotating member 411 to ensure the accuracy of the rotation angle of the first reflector 42.

[0041] Reference Figure 5 As shown, the rotating table 41 is placed in a vertical state, that is, the rotating member 411 rotates around a first direction. At this time, the first reflector 42 is provided with a first reflective surface 420. When the first reflector 42 is in the first state, the laser beam emitted by the first laser 1 is reflected to the processing head 3 through the first reflective surface 420. When the rotating table 41 rotates around the first direction by a preset angle so that the first reflector 42 is in the second state, the laser beam emitted by the second laser 2 is reflected to the processing head 3 through the first reflective surface 420.

In other embodiments, the rotating table 41 is placed in a horizontal state, that is, the rotating member 411 rotates around the second direction. At this time, the first reflector 42 is provided with a first reflective surface 420 and a second reflective surface 421. When the first reflector 42 is in the first state, the laser beam emitted by the first laser 1 is reflected to the processing head 3 through the first reflective surface 420. When the first reflector 42 is in the second state, the laser beam emitted by the second laser 2 is reflected to the processing head 3 through the second reflective surface 421.

[0043] Reference Figure 1 and Figure 2As shown, the laser processing device further includes a second reflector 6 and a third reflector 7. The second reflector 6 is arranged on the laser light path emitted by the first laser 1, and is used to reflect the laser beam emitted by the first laser 1 to the first reflector 42. The third reflector 7 is arranged on the laser light path emitted by the second laser 2, and is used to reflect the laser beam emitted by the second laser 2 to the first reflector 42.

[0044] When the first reflector 42 is in the first state, the reflective surface of the second reflector 6 is arranged parallel to the reflective surface of the first reflector 42. When the first reflector 42 is in the second state, the reflective surface of the third reflector 7 is arranged parallel to the reflective surface of the first reflector 42. In the first direction, the angle A between the first reflector 42 and the first direction is 45°, the angle B between the second reflector 6 and the first direction is 45°, and the angle C between the third reflector 7 and the first direction is 45°, so as to ensure that the first reflector 42, the second reflector 6 and the third reflector 7 are arranged in a stacked manner in the second direction, thereby reducing the lateral occupied space of the laser processing device.

[0045] In this embodiment, in the first direction, the angle A between the first reflector 42 and the first direction is 45°, the angle B between the second reflector 6 and the first direction is 45°, and the angle C between the third reflector 7 and the first direction is 45°. It can be understood that in other embodiments, in the first direction, the angle between the first reflector 42 and the first direction can also be other angles, such as 30°. At this time, the angle B between the second reflector 6 and the first direction and the angle C between the third reflector 7 and the first direction can be set according to the positions of the second reflector 6, the third reflector 7, the first laser 1 and the second laser 2.

[0046] In a specific application scenario, when processing by the first laser 1 is required, the control card 5 is used to control the rotation of the rotating table 41 so that the first reflector 42 is in the first state, and then the control card 5 controls the first laser 1 to be turned on, and the laser beam emitted by the first laser 1 is reflected to the first reflector 42 through the second reflector 6, and then reflected to the processing head 3 through the first reflector 42, so that the workpiece is processed by the first laser 1; when processing by the second laser 2 is required, the control card 5 is used to control the rotation of the rotating table 41 so that the first reflector 42 is in the second state, and then the control card 5 controls the second laser 2 to be turned on, and the laser beam emitted by the second laser 2 is reflected to the first reflector 42 through the third reflector 7, and then reflected to the processing head 3 through the first reflector 42, so that the workpiece is processed by the second laser 2, thereby realizing two laser processing methods.
