[0038] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0039] The utility model provides Figures 1 to 4As shown in the figure, a fiber laser marking machine is designed to solve the disadvantage of existing fiber laser marking machines that they are highly dependent on manual labor during use.

[0040] The fiber laser marking machine mainly includes: a feeding module 100, a camera module 200, a rotating module, a laser module 500, a discharging module 600, and a pressure sensor 400 arranged on the rotating module.

[0041] Material 700 has a marking surface 710. The marking area is located on the rotating module. The laser module 500 is used to mark the marking surface 710 of the material 700 located in the marking area. The feeding module 100 is used to move the material 700 to the marking area, replacing the manual loading operation. The camera module 200 is positioned toward the marking area and is used to identify the angle of the marking surface 710 of the material 700 located in the marking area. The camera module 200 can replace the manual operation of using a magnifying glass to identify the angle of the material 700. Specifically, using the camera module 200 to identify the angle of the marking surface 710 of the material 700 is conventional technology. The rotation module is used to change the angle of the marking surface 710 of the material 700 located in the marking area. This rotation module can replace manual adjustment of the product angle. When the marking surface 710 of the material 700 is aligned with the laser module 500, marking can be performed. Compared with manual adjustment, the test accuracy is greatly improved and manpower is effectively saved. The discharge module 600 is used to move the material 700 located in the marking area to a predetermined position. This can replace manual unloading operations. Among them, the pressure sensor 400 is in contact with the material 700 located in the marking area. The pressure sensor 400 is used to contact the material 700 located in the marking area to determine whether the material 700 is present in the marking area, thereby providing a signal to the camera module 200 to start taking pictures.

[0042] Existing fiber laser marking machines have several operational inconveniences. First, operators must manually remove metal parts from a 700-piece tray and place them on a workpiece, wearing finger cots to prevent contamination or damage. Next, they use a magnifying glass to adjust the product angle to ensure the marking position is accurate, and then activate the laser to mark. This process not only relies on the coordinated operation of both hands but also requires frequent repetition to meet high production demands, resulting in high workload intensity.

[0043] The utility model can replace the manual loading operation through the feeding module 100, can replace the manual operation of using a magnifying glass to identify the material 700 angle through the camera module 200, can replace the manual operation of adjusting the product angle through the rotating module, and can replace the manual unloading operation through the discharging module 600. Compared with manual measurement, the test accuracy is greatly improved and manpower is effectively saved.

[0044] In some embodiments, as Figures 1 to 4 As shown in , the rotating module includes: a clamp 310 and a drive unit 320. The clamp 310 is used to fix the material 700. The clamp 310 is rotatably arranged on the frame 720 along the vertical rotation axis. The marking area is located on the top surface of the clamp 310. The clamp 310 is driven by the drive unit 320 to rotate.

[0045] In actual use, marking surface 710 is located horizontally on the surface of material 700. When material 700 is moved to the marking area via feed module 100, there is no guarantee that marking surface 710 will align with laser module 500. Driven by drive unit 320, fixture 310 rotates, thereby driving material 700 and rotating marking surface 710 until it aligns with laser module 500. Marking can then begin. Preferably, laser module 500 and marking surface 710 are located on the same horizontal plane.

[0046] In some embodiments, as Figures 1 to 2 As shown in FIG, the driving unit 320 is a numerically controlled indexing plate, on which the fixture 310 is mounted. The fixture 310 is driven to rotate by the numerically controlled indexing plate. The numerically controlled indexing plate has a high precision and can fine-tune the angle of the marking surface 710.

[0047] In some embodiments, as Figures 1 to 2 As shown in FIG, the marking area is located on the top surface of pressure sensor 400, which is a vacuum sensor. Pressure sensor 400 can be installed on the top surface of fixture 310, or the fixture 310 can be installed on the top surface of pressure sensor 400. When material 700 is fixed to fixture 310, material 700 directly or indirectly applies pressure to pressure sensor 400. Pressure sensor 400 can obtain this signal to determine whether material 700 is within the marking area, thereby providing a signal to camera module 200 to start taking pictures, preventing camera module 200 from running continuously and saving energy.

[0048] In some embodiments, as Figure 1 、 Figure 4 As shown in FIG, the camera module 200 is located above the marking area, and the feeding module 100, the laser module 500, and the discharging module 600 are respectively arranged around the marking area.

[0051] In some embodiments, as Figure 1 、 Figure 4 As shown in FIG, the discharging module 600 includes: a discharging tray 610 , a waste tray 620 and a three-axis discharging unit 630 .

[0052] The waste tray 620 is spaced apart from the discharge tray 610. The discharge tray 610 is used to hold a plurality of materials 700. The three-axis discharge unit 630 is used to move the materials 700 located on the marking area to the discharge tray 610 or the waste tray 620. Specifically, the three-axis discharge unit 630 is an XYZ three-axis slide.

[0053] In some embodiments, as Figure 1 、 Figure 4 As shown in FIG, the feeding module 100 includes: a feeding negative pressure suction cup 130, which is arranged on the three-axis feeding unit 120. The feeding negative pressure suction cup 130 is driven by the three-axis feeding unit 120 to move the multiple materials 700 on the feeding tray 110 into the marking area in sequence;

[0054] The discharge module 600 also includes: a discharge negative pressure suction cup 640, which is arranged on the three-axis discharge unit 630. The discharge negative pressure suction cup 640 is driven by the three-axis discharge unit 630 to move the material 700 located on the marking area to the discharge tray 610 or the waste tray 620.

[0055] The feed negative pressure suction cup 130 and the discharge negative pressure suction cup 640 are both connected to a negative pressure pump. The feed negative pressure suction cup 130 and the discharge negative pressure suction cup 640 can suck up the material 700 through negative pressure via the corresponding negative pressure pump.

[0056] In some embodiments, as Figure 1 、 Figure 4 As shown in the figure, the feed tray 110 has a plurality of first positioning grooves 111 provided on the top surface of the feed tray 110, and the first positioning grooves 111 are used to fix the material 700;

[0057] The discharge tray 610 has a plurality of second positioning grooves 611 on its top surface, and the second positioning grooves 611 are used to fix the material 700;

[0058] The waste tray 620 has a plurality of third positioning grooves 621 on its top surface, and the third positioning grooves 621 are used to fix the material 700;

[0059] The marking area is set between the feed tray 110 and the discharge tray 610, and the waste tray 620 and the discharge tray 610 are set side by side and spaced apart.

[0060] In summary, a fiber laser marking machine is provided, which includes a feed module, a camera module, a rotary module, a pressure sensor, a laser module, and a discharge module, all of which are arranged on a frame. The feed module is used to move the material to the marking area, the camera module is used to identify the angle of the marking surface of the material, the rotary module is used to change the angle of the marking surface of the material, the pressure sensor is in contact with the material, the laser module is used to mark the marking surface, and the discharge module is used to move the material located in the marking area to a predetermined position.
