[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0038] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] As shown in Figures 1 and 2, at least one embodiment provides a laser marking device, including: a mounting platform 1 on which a mounting frame 11 is disposed; a laser 2 disposed on the mounting platform 1 for emitting laser light; a beam splitting module 3 disposed on the mounting platform 1 for receiving the laser light and splitting it into several sub-lasers, and causing the sub-lasers to be emitted toward the z-axis; a reflection module 4 disposed on the mounting frame 11 for changing the emission direction of each sub-laser to be emitted toward the y-axis; and a marking module 5, which includes: a first driving unit 51 disposed on the mounting frame 11, a second driving unit 52 disposed on the first driving unit 51, and several marking units 53 disposed on the second driving unit 52; wherein the first driving unit 51 is adapted to drive the second driving unit 52 and each marking unit 53 to move as a whole along the y-axis, and the second driving unit 52 is adapted to drive each marking unit 53 to move as a whole along the z-axis.
[0041] In this embodiment, the beam splitting module 3, the reflection module 4, and the scribing module 5 are set separately. When the laser scribing device is working, it is only necessary to drive the scribing module 5 to move along the y-axis and z-axis to scribing. During this process, the beam splitting module 3 and the reflection module 4 will not move, thereby reducing the load on the driver.
[0042] As shown in Figure 2, in some embodiments, the first drive unit 51 includes: a first driver 510 and a mounting frame 511; the first driver 510 is disposed on the mounting bracket 11, the mounting frame 511 is disposed on the first driver 510, and the second drive unit 52 and each scribing unit 53 are disposed within the mounting frame 511; wherein, the first driver 510 is adapted to move the second drive unit 52 and each scribing unit 53 as a whole along the y-axis by driving the mounting frame 511 to move along the y-axis.
[0043] In this embodiment, since the beam splitting module 3 and the reflection module 4 do not move with the scribing module 5, it is necessary to ensure that the scribing module 5 can always stably receive the laser during its movement. Therefore, in this embodiment, the scribing module 5 is divided into a first driving unit 51, a second driving unit 52, and several scribing units 53. The first driving unit 51 moves in the y-axis direction, which is the same as the direction of the sub-laser reflected by the reflection module 4, thereby ensuring that the scribing units 53 can always stably receive the laser.
[0044] As shown in Figure 2, in some embodiments, the second drive unit 52 includes a second driver 521 and a mounting plate 522; the second driver 521 is disposed within the mounting frame 511, the mounting plate 522 is disposed on the second driver 521, and each scribing unit 53 is disposed on the mounting plate 522; wherein, the second driver 521 is adapted to drive the mounting plate 522 to move along the z-axis so as to drive each scribing unit 53 to move as a whole along the z-axis.
[0045] In this embodiment, the second driving unit 52 is used to drive the scribing unit 53 to move along the z-axis. This direction is orthogonal to the direction of the sub-laser reflected by the reflection module 4. When the second driving unit 52 drives the scribing unit 53 to move along the z-axis, the scribing unit 53 will not receive the laser.
[0046] Therefore, in order to solve the above problems, as shown in Figure 2, the scribing module 5 also includes: a plurality of reflective units 54; the reflective unit 54 includes: a pair of first reflective mirrors 54a; wherein the two first reflective mirrors 54a are respectively disposed on the mounting frame 511 and the mounting plate 522, and are adapted to receive the sub-laser reflected by the reflective module 4 along the y-axis, and after being rotated and reflected along the z-axis, it is reflected again along the y-axis.
[0047] In this embodiment, each scribing unit 53 is equipped with a reflection unit 54. The reflection unit 54 uses a pair of first reflectors 54a respectively set on the mounting frame 511 and the mounting plate 522 to reflect the sub-laser reflected by the reflection module 4 along the y-axis, rotates it along the z-axis, and then reflects it along the y-axis again. This ensures that when the second driving unit 52 moves the scribing unit 53 along the z-axis, it only adjusts the distance of the reflection unit 54 rotating along the z-axis and does not affect the sub-laser reflected along the y-axis. This ensures that the scribing unit 53 can always stably receive the laser when the second driving unit 52 is working.
[0048] As shown in Figure 3, in some embodiments, the scribing unit 53 includes: a third driver 531, a second reflector 532, and a focusing lens 533; wherein the third driver 531 is disposed on the mounting plate 522, and the second reflector 532 and the focusing lens 533 are both disposed on the third driver 531; the third driver 531 is adapted to adjust the spacing between adjacent sub-lasers by moving along the y-axis.
[0049] In this embodiment, the scribing unit 53 reflects the received sub-laser in the y-axis direction into the z-axis direction through the second reflector 532, thereby scribing lines onto the product 7 being processed.
[0050] As shown in Figure 3, in some embodiments, the focusing mirror 533 is disposed in front of or below the second reflecting mirror 532 and is located in the optical path of the sub-laser; wherein the second reflecting mirror 532 is adapted to receive the sub-laser emitted along the y-axis after being processed by the first reflecting mirror 54a, and reflect the sub-laser along the z-axis.
[0051] As shown in Figure 4, in some embodiments, the beam splitting module 3 includes: a beam splitting unit; the beam splitting unit includes: a plurality of third reflectors 31 and a plurality of beam splitters 32; the beam splitters 32 are adapted to receive laser light and reflect part of the laser light and reflect part of the laser light, and the third reflectors 31 are adapted to reflect the received laser light; wherein, by arranging the third reflectors 31 and the beam splitters 32 as required, the laser light emitted by the laser 2 is split into a plurality of laser beams.
[0052] In this embodiment, the third reflector 31 and the beam splitter 32 are arranged according to requirements to divide a whole laser beam into several sub-beams. The arrangement position and method are conventional technical means.
[0053] As shown in Figure 4, in some embodiments, the beam splitting module 3 further includes: a beam expander 33 and a plurality of motorized waveplates 34; wherein the beam expander 33 is located upstream of the beam splitting unit, and the motorized waveplates 34 are located downstream of the beam splitting unit; the beam expander 33 is adapted to receive the laser emitted by the laser 2 and expand it before sending it to the beam splitting unit; the motorized waveplates 34 are adapted to receive the sub-lasers sent by the beam splitting unit and send them to the z-axis.
[0054] As shown in Figure 1, in some embodiments, the reflection module 4 includes: a plurality of fourth reflectors 41; each fourth reflector 41 is disposed on the mounting frame 11 and is adapted to receive the sub-laser transmitted by the electric waveplate 34 and reflect it to the y-axis.
[0055] In some embodiments, a fourth driver 6 is provided on the mounting platform 1; wherein the fourth driver 6 is adapted to drive the processed product 7 to move along the x-axis.
[0056] In summary, this laser marking device separates the beam splitting module 3, the reflection module 4, and the marking module 5. When the laser marking device is working, only the marking module 5 needs to be moved along the y-axis and z-axis to mark lines. During this process, the beam splitting module 3 and the reflection module 4 do not move, thereby reducing the load on the driver. At the same time, by setting a reflection unit in the marking module 5, the marking module 5 can stably receive laser light when moving along the y-axis and z-axis.

Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0064] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation.
