DETAILED DESCRIPTION
[0035] The technical solution of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0036] Please refer to Figures 1 and 2. Figure 1 is an assembly diagram of a laser processing equipment provided in one embodiment of the present application, and Figure 2 is a structural diagram of a laser processing device provided in one embodiment of the present application.
[0037] The laser processing equipment 100 provided in one embodiment of the present application performs laser processing on a workpiece (not shown) by using laser as a processing medium. The laser processing processes include but are not limited to cutting, engraving and other processes.
[0038] In this embodiment, the laser processing device 100 is a desktop laser engraving and cutting machine. It is understood that in other embodiments, the laser processing device 100 includes but is not limited to other laser processing devices, and this application does not limit this.
[0039] Laser processing equipment 100 includes a laser processing device 10, a base 30, and a housing 50. The laser processing device 10 is used to emit laser light for laser processing of a workpiece. The laser processing device 10 is mounted on the base 30, which also supports the workpiece. The laser light emitted by the laser processing device 10 can move relative to the base 30 to laser process the workpiece on the base 30. The housing 50 is mounted on the base 30, and the housing 50 and the base 30 enclose a processing space within which the laser processing device 10 is located.
[0040] The housing 50 is provided with a cover plate 51, which is rotatably mounted thereon and can open or close the processing space within the housing 50 to facilitate the operator's insertion and removal of workpieces. The base 30 and the housing 50 can be fixedly connected. The blocking and / or filtering effects of the base 30 and the housing 50 prevent the laser generated by the laser processing device 10 from spilling out during operation and potentially injuring the operator.
[0041] Please refer to FIG. 2 and FIG. 3 . FIG. 3 is a second structural diagram of a laser processing device provided in one embodiment of the present application.
[0042] The laser processing device 10 includes a support frame 11, a first power supply 12, a laser 13, and a main control circuit board 14. The support frame 11 is fixed to the base 30, and the first power supply 12, laser 13, and main control circuit board 14 are all mounted on the support frame 11. The first power supply 12 is electrically connected to the laser 13 and is a high-voltage power supply. The voltage generated by the first power supply 12 is greater than or equal to 110 volts. When the voltage generated by the first power supply 12 reaches 30,000 volts, the laser 13 can emit laser light.
[0043] Specifically, the support frame 11 includes a low-voltage zone 102 and a high-voltage zone 101, and the low-voltage zone 102 and the high-voltage zone 101 are spaced apart. The first power supply 12 is arranged at the position of the high-voltage zone 101 of the support frame 11, and the main control circuit board 14 is arranged at the position of the low-voltage zone 102 of the support frame 11. In other words, the area where the first power supply 12 is located in the support frame 11 is the high-voltage zone 101. The area where the main control circuit board 14 is located in the support frame 11 is the low-voltage zone 102. In the laser processing device 10 provided in the present application, the layout is divided into the high-voltage zone 101 and the low-voltage zone 102 by the support frame 11, and the high-voltage zone 101 and the low-voltage zone 102 are spaced apart. The first power supply 12 is arranged in the high-voltage zone 101. The main control circuit board 14 is arranged in the low-voltage area 102, so that the first power supply 12 and the main control circuit board 14 are arranged in partitions and intervals, which can reduce the interference of the first power supply 12 on the main control circuit board 14, and thereby reduce the probability of the chip in the main circuit board 14 losing control and crashing or getting stuck, which is beneficial to improving the overall performance of the laser processing device 10.
[0044] Referring to Figures 2 and 3, in this embodiment, the support frame 11 includes a first support member 111, a second support member 112, a third support member 113 and a fourth support member 114. The first support member 111, the second support member 112, the third support member 113 and the fourth support member 114 are connected end to end in sequence, and the first support member 111 and the third support member 113 are arranged opposite to each other, and the second support member 112 and the fourth support member 114 are arranged opposite to each other.
[0045] The first support member 111 is arranged substantially parallel to the third support member 113, and the second support member 112 is arranged substantially parallel to the fourth support member 114. The first support member 111 is perpendicular to the second support member 112, and the third support member 113 is perpendicular to the fourth support member 114. It is understood that in other embodiments, the first support member 111 and the third support member 113 may not be parallel, the second support member 112 and the fourth support member 114 may not be parallel, the first support member 111 and the second support member 112 may not be perpendicular, and the third support member 113 and the fourth support member 114 may not be perpendicular, and this application does not impose any limitation on this.
[0046] The first power supply 12 is disposed on a side of the fourth support member 114 facing away from the second support member 112, and is located at an end of the fourth support member 114 that is proximal to the third support member 113. In other words, the first power supply 12 is disposed outside the fourth support member 114 and proximal to the third support member 113. The first power supply 12 is used to provide a high operating voltage to the laser 13, enabling the laser processing apparatus 10 to emit laser light and thereby process a workpiece.
[0047] The laser 13 is disposed on the third support member 113 and fixed to the side of the third support member 113 facing away from the base 30. The laser 13 is electrically connected to the first power supply 12, and the first power supply 12 enables the laser 13 to emit laser light, thereby processing the workpiece.
[0048] Specifically, the main control circuit board 14 is disposed on a side of the second support member 112 facing away from the fourth support member 114, and is located at the end of the second support member 112 that is closest to the first support member 111. In other words, the main control circuit board 14 is disposed outside the second support member 112 and adjacent to the first support member 111. The main control circuit board 14 is electrically connected to the laser 13 and can control the laser 13 to emit laser light, thereby controlling the laser processing apparatus 10's processing of the workpiece.
[0049] In the embodiment of the present application, the first support member 111, the second support member 112, the third support member 113 and the fourth support member 114 are connected end to end in sequence to form a rectangular frame, and the first power supply 12 and the main control circuit board 14 are located at the two end points of a diagonal line of the rectangular frame, so that the distance between the first power supply 12 and the main control circuit board 14 is larger, which can reduce the interference of the first power supply 12 on the main circuit board 14, thereby reducing the probability of the chip in the main circuit board 14 losing control and freezing or jamming, which is beneficial to improving the overall performance of the laser processing device 10.
[0050] Referring to Figures 2 and 3 , the laser processing apparatus 10 further includes a second power supply 15. The second power supply 15 is disposed on a side of the fourth support member 114 facing away from the second support member 112. The second power supply 15 is also located on a side of the fourth support member 114 that is closer to the first support member 111. In other words, the second power supply 15 is disposed outside the fourth support member 114 and closer to the first support member 111. The second power supply 15 is electrically connected to the main control circuit board 14 to supply power to the main control circuit board 14, enabling the main control circuit board 14 to operate normally.
[0051] In this embodiment, the filter 16 is disposed on the base 30. One end of the filter 16 is electrically connected to the first power supply 12 and the second power supply 15, and the other end of the filter 16 is connected to an external power supply to filter the power supply signal so that the first power supply 12 and the second power supply 15 can obtain a stable power supply signal. It is understood that in other embodiments, the filter 16 can be disposed on the side of the fourth support member 114 facing away from the second support member 112, and this application is not limited to this.
[0052] Please refer to Figures 2, 3, 4 and 5. Figure 4 is a third structural schematic diagram of a laser processing device provided in one embodiment of the present application. Figure 5 is a fourth structural schematic diagram of a laser processing device provided in one embodiment of the present application.
[0053] In this example, the laser processing device 10 further includes a power interface 17, which is disposed on a side of the third support member 113 facing away from the first support member 111. The power interface 17 is located at an end of the third support member 113 that is proximate to the fourth support member 114. In other words, the power interface 17 is disposed outside the third support member 113 and proximate to the fourth support member 114. One end of the power interface 17 is electrically connected to the filter 16, and the other end of the power interface 17 is electrically connected to an external power source, enabling the external power source to power the laser processing device 10 and the laser processing equipment 100, thereby enabling the laser 13 and the main control circuit board 14 to function properly.
[0054] Furthermore, the laser processing device 10 also includes a switch 18, which is arranged on the side of the fourth support member 114 away from the second support member 112, and the switch 18 is electrically connected between the first power supply 12 and the power interface 17. The switch 18 is used to control the power on and off between the first power supply 12 and the power interface 17 (or external power supply). In this embodiment, the switch 18 is an emergency stop switch. By setting the switch 18, the laser 13 can be powered off in an emergency, thereby stopping the laser from emitting, which is beneficial to improving the safety of the laser processing device 10 during the processing process. It can be understood that in an emergency, the emergency stop switch can automatically power off or manually power off. By setting the emergency stop switch, the safety of the process of processing the workpiece by the laser processing device 10 is improved.
[0055] Referring to Figures 2, 3, 4, and 5, the laser processing device 10 includes a first connecting line 193 and a second connecting line 194. The first connecting line 193 is a high-voltage connecting line, while the second connecting line 194 is a low-voltage connecting line. The first connecting line 193 is connected between the first power supply 12 and the laser 13, while the second connecting line 194 is connected between the second power supply 15 and the main control circuit board 14. Specifically, a wire groove 1110 is provided on the first support member 111. The wire groove 1110 extends through the first support member 111 from the second support member 112 to the fourth support member 114, and the second connecting line 194 is received within the wire groove 1110. The first connecting line 193 is provided at the junction of the third support member 113 and the fourth support member 114 to separate the first connecting line 193 and the second connecting line 194.
[0056] In this embodiment, since the first connecting line 193 and the second connecting line 194 are separated, the interference of the first connecting line 193 (high-voltage connecting line) on the second connecting line 194 (low-voltage connecting line) is reduced, which is beneficial to improving the routing stability of the first connecting line 193 and the second connecting line 194, thereby improving the overall performance of the laser processing device 10.
[0057] Referring to Figures 2 and 3 , the laser processing apparatus 10 further includes a cooling box 191 and a cooling control board 192. The cooling box 191 is disposed on the side of the second support member 112 facing away from the fourth support member 114, and is located at the end of the second support member 112 near the third support member 113. In other words, the cooling box 191 is disposed outside the second support member 112 and adjacent to the third support member 113. The cooling box 191 communicates with the laser 13 and forms a water circulation path, which is used to cool the laser 13 and prevent overheating and tube bursting during operation. The cooling control board 192 is disposed on the side of the second support member 112 facing away from the fourth support member 114. The cooling control board 192 is located between the cooling box 191 and the main control circuit board 14, and is electrically connected to the cooling box 191 and the main control circuit board 14, enabling the cooling box 191 to effectively cool the laser 13. In this embodiment, the cooling box 191 is a water tank, and liquid in the water tank can circulate in the laser 13 to cool the laser 13.
[0058] Referring to Figures 2 and 4 , the laser 13 includes a positive terminal 131 and a negative terminal 132. Laser light from the laser 13 is emitted from the negative terminal 132. The positive terminal 131 is located on a side of the laser 13 near the fourth support member 114. It is electrically connected to the first power source 12 to enable the laser 13 to emit laser light. The negative terminal 132 is located on a side of the laser 13 near the second support member 112. It is electrically connected to the main control circuit board 14. Laser light emitted from the negative terminal 132, after optical path conversion, can be converted into laser light for processing a workpiece.
[0059] It is understood that in some other embodiments, the laser processing apparatus 10 may further include a shielding cover 195 for shielding the high voltage generated by the first power supply 12 from interfering with other electronic components. The shielding cover 195 is disposed at the junction of the third support member 113 and the fourth support member 114. The first power supply 12 and the positive terminal 131 of the laser 13 are both housed within the shielding cover 195.
[0060] By setting the shielding cover 195, the first power supply 12 and the positive terminal 131 of the laser 13 are isolated from other electronic components, which can block the high voltage generated by the first power supply 12 from interfering with other electronic components such as the main control circuit board 14, thereby reducing the probability of the chip in the main control circuit board 14 losing control and causing a crash or jam, which is beneficial to improving the overall performance of the laser processing device 10.
[0061] In some other embodiments, the shielding cover 195 of the laser device 10 can be only installed on the outside of the first power supply 12, that is, only the first power supply 12 is housed in the shielding cover 195, which can also reduce the interference of the high voltage generated by the first power supply 12 on other electronic components such as the main control circuit board 14, thereby reducing the probability of the chip in the main control circuit board 14 losing control and causing a crash or jam, which is beneficial to improving the overall performance of the laser processing device 10.
[0062] It is understandable that the present application does not limit the structure of the support frame 11 , and the first power supply 12 and the main control circuit board 14 can be arranged in partitions.
[0063] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
