[0041] The utility model provides a kind of laser host computer 100.

[0042] In combination withFigures 1 to 3 In an embodiment of the present application, the laser host 100 comprises a shell assembly 10, a laser assembly 20 and a control module 40. The shell assembly 10 is provided with a receiving space 11, an air inlet 12 and an air outlet 13 which communicate with the receiving space 11. The laser assembly 20 is arranged in the receiving space 11. The laser assembly 20 is provided with a heat dissipation air duct 27 and a laser generating module arranged in the heat dissipation air duct 27. An air inlet end 28 of the laser assembly 20 is arranged towards the air inlet 12. An air outlet end 29 of the laser assembly 20 is arranged towards the air outlet 13. The air inlet end 28 and the air outlet end 29 respectively abut against the inner wall of the shell assembly 10. The control module 40 is arranged in the receiving space 11 and electrically connected with the laser assembly 20.

[0043] The laser host 100 provided in the present application can be applied in a laser processing device for generating and outputting laser, so that the laser processing device can perform laser welding, laser cutting, laser marking, laser cleaning and other working operations by using laser. The laser processing device further comprises a laser output head and an optical fiber. The laser output head is connected with the laser host 100 through the optical fiber. The laser generated by the laser host 100 can be transmitted to the laser output head through the optical fiber and emitted through the laser output head. The laser output head can be arranged as a handheld welding gun. In some embodiments, the laser host 100 can also comprise a driving assembly. The laser output head is fixed on the driving assembly, so that the laser output head can be driven to move by the driving assembly, thereby realizing automatic processing.

[0044] The laser host 100 provided in the present application comprises a shell assembly 10, a laser assembly 20 and a control module 40. The laser assembly 20 and the control module 40 are arranged in the receiving space 11 of the shell assembly 10. The control module 40 is used for controlling the running state of the laser assembly 20 and can provide electric energy for the laser assembly 20. Optionally, the control module 40 can comprise a main control board 431 and a power board assembly 433, and can also comprise a laser power supply assembly 42, a switching power supply and an AC contactor and the like.

[0045] In the embodiment of the present application, the laser assembly 20 is provided with a heat dissipation air duct 27, and the laser generating module for generating laser in the laser assembly 20 is arranged in the heat dissipation air duct 27. When the airflow flows through the heat dissipation air duct 27, the heat inside the laser assembly 20 can be taken away, thereby achieving heat dissipation of the laser assembly 20. The air inlet end 28 of the laser assembly 20 is arranged opposite to part of the air inlet 12 of the shell assembly 10, and the air inlet end 28 of the laser assembly 20 abuts against the inner wall of the shell assembly 10, so that the air inlet end 28 of the laser assembly 20 is isolated from the accommodation space 11 outside the laser assembly 20. The air outlet end 29 of the laser assembly 20 is arranged opposite to part of the air outlet 13 of the shell assembly 10, and the air outlet end 29 of the laser assembly 20 abuts against the inner wall of the shell assembly 10, so that the air outlet end 29 of the laser assembly 20 is isolated from the accommodation space 11 outside the laser assembly 20. In the specific application, the airflow is driven by the driving member such as the heat dissipation fan 30 to enter the accommodation space 11 from the air inlet 12. At this time, the airflow is divided into two parts. One part of the airflow enters the heat dissipation air duct 27 from the air inlet end 28 of the laser assembly 20, and then is discharged outward through the air outlet end 29 of the laser assembly 20 and the air outlet 13 of the shell assembly 10. The other part of the airflow enters part of the accommodation space 11 outside the laser assembly 20 from the air inlet 12, and then is discharged outward from the air outlet 13 of the shell assembly 10. The airflow in the accommodation space 11 outside the laser assembly 20 cannot flow into the heat dissipation air duct 27 in the shell assembly 10, so that the heat generated by the control module 40 can be prevented from entering the heat dissipation air duct 27 with the airflow, thereby avoiding the influence of the heat generated by the control module 40 on the laser generating module, so that the temperature inside the laser assembly 20 is prevented from being too high, and the continuous working time of the laser host 100 is improved.

[0046] That is, the air inlet end 28 and the air outlet end 29 of the laser assembly 20 abut against the inner wall of the shell assembly 10, so that the heat dissipation air duct 27 inside the laser assembly 20 is isolated from the accommodation space 11 outside the laser assembly 20. When the laser host 100 works, the heat generated by the control module 40 cannot enter the heat dissipation air duct 27 inside the laser assembly 20 with the airflow in the accommodation space 11, so that the influence of the heat generated by the control module 40 on the laser generating module can be avoided, thereby preventing the temperature inside the laser assembly 20 from being too high, and improving the continuous working time of the laser host 100.

[0047] Please refer to Figure 4In an embodiment, the laser assembly 20 further comprises a safety relay 26, which is arranged outside the heat dissipation air duct 27. The safety relay 26 can function as at least one of the following: fault protection, safety input control, overload protection, short circuit protection, temperature protection, and leakage protection. For example, when a machine safety circuit fails, the safety relay 26 can stop the power supply of the machine in time to avoid danger. The safety relay 26 can also be used to ensure that the machine can only start when the safety input (such as a safety switch or light curtain) is normal, so as to prevent safety hazards caused by abnormal safety input. In addition, the safety relay 26 can be used to cut off the power supply when an abnormal current is detected. The safety relay 26 can also automatically cut off the power supply when the internal temperature of the device is too high to prevent the device from being damaged by overheating.

[0054] In the present embodiment, the first sealing member 24 is generally provided with a certain elasticity, and when abutting against the inner wall of the housing assembly 10, the first sealing member 24 can be elastically deformed to fit the inner wall of the housing assembly 10, thereby achieving a better sealing effect.

[0055] Referring to Figure 3 and Figure 4 In an embodiment, the laser assembly 20 further comprises a second sealing member 25, which is arranged at the air outlet end 29 and abuts against the inner wall of the housing assembly 10.

[0056] In the present embodiment, the second sealing member 25 is generally provided with a certain elasticity, and when abutting against the inner wall of the housing assembly 10, the second sealing member 25 can be elastically deformed to fit the inner wall of the housing assembly 10, thereby achieving a better sealing effect. Optionally, the second sealing member 25 can be made of, but not limited to, silicone, rubber or other elastic materials, which are not limited herein.

Through the arrangement of the support 50, the stability of the laser assembly 20 fixed in the accommodation space 11 can be improved, and the laser assembly 20 can be prevented from shaking and being offset.

[0059] Referring to Figure 3 and Figure 5 In an embodiment, the laser host 100 further includes a cooling fan 30, which is arranged in the accommodation space 11.

[0060] In the embodiment, the laser host 100 further includes a cooling fan 30 for driving the flow of air, which is arranged in the accommodation space 11 and located outside the laser assembly 20. The cooling fan 30 can generate a driving force for forming an air circulation. When the cooling fan 30 is running, the air flows into the accommodation space 11 from the air inlet 12, and the air is divided into two parts. One part of the air flows into the cooling air duct 27 from the air inlet end 28 of the laser assembly 20, and then is discharged outward through the air outlet end 29 of the laser assembly 20 and the air outlet 13 of the shell assembly 10. The other part of the air flows into the part of the accommodation space 11 outside the laser assembly 20 from the air inlet 12, and then is discharged outward from the air outlet 13 of the shell assembly 10. The air circulation in the accommodation space 11 outside the laser assembly 20 will not enter the cooling air duct 27, so that the heat generated by the control module 40 can be prevented from entering the cooling air duct 27 with the air flow, thereby avoiding the influence of the heat generated by the control module 40 on the laser generating module, so as to avoid the temperature of the laser generating module being too high, and to improve the continuous working time of the laser host 100.

[0061] Referring to Figure 2 , Figure 3 and Figure 5 In an embodiment, the control module 40 includes a fixing frame 41, a laser power supply assembly and a main control assembly 43. The fixing frame 41 is arranged in the accommodation space 11 and connected with at least one of the laser assembly 20 and the shell assembly 10, and the cooling fan 30 is arranged in the fixing frame 41. The laser power supply assembly is arranged in the fixing frame 41 and electrically connected with the laser assembly 20. The main control assembly 43 is arranged in the fixing frame 41 and electrically connected with the laser assembly 20.

[0062] In the embodiment, the control module 40 comprises a fixing frame 41 as a bearing base, which can be provided as a plate structure or a frame structure. The fixing frame 41 can be connected with the laser assembly 20 to be fixed in the accommodating space 11, or the fixing frame 41 can be connected with the shell assembly 10, or the fixing frame 41 is connected with both the laser assembly 20 and the shell assembly 10, so that the fixing frame 41 can be stably installed. In addition, the heat dissipation fan 30 is installed on the fixing frame 41, so that no other fixing structure is needed to fix the heat dissipation fan 30, and the control module 40 and the heat dissipation fan 30 are combined to form an integral structure, which is convenient for overall disassembly and assembly.

[0063] The control module 40 comprises a laser power supply assembly for providing electric energy for the laser assembly 20, and a main control assembly 43 as a control system. The main control assembly 43 and the laser power supply assembly are both arranged on the fixing frame 41, so that the control module 40 forms an integral structure, which is convenient for overall disassembly and assembly of the control module 40, and improves the disassembly and assembly convenience.

[0064] In combination with reference to Figure 2 and Figure 5 In an embodiment, the heat dissipation fan 30 is arranged on the side of the laser power supply assembly facing the air outlet 13.

[0065] In the embodiment, the heat dissipation fan 30 is arranged side by side with the laser power supply assembly. It can be understood that when the heat dissipation fan 30 is running, the air volume and air flow rate at the position adjacent to the heat dissipation fan 30 are also relatively high. Therefore, the laser power supply assembly is arranged on the air inlet side of the heat dissipation fan 30, so that more air flow can be used to dissipate heat of the laser power supply assembly with high heat generation, and the heat dissipation efficiency of the laser power supply assembly is improved.

[0066] In combination with reference to Figure 2 , Figure 3 and Figure 5 In an embodiment, the laser power supply assembly is arranged at the top region of the fixing frame 41, and the main control assembly 43 is arranged below the laser power supply assembly.

In this way, the fixing frame 41 can play a role in heat insulation, and the heat generated by the laser power supply assembly and the main control assembly 43 can be reduced to be transmitted to the laser assembly 20, so as to reduce the influence of the heat generated by the control module 40 on the laser assembly 20.

[0071] In the embodiment, the main control assembly 43 includes the main control board 431, the main control switching power supply 432, and the power board assembly 433 arranged side by side, the main control board 431 serves as a core control unit and can be used for signal processing, system control, and power management; can be used for receiving and processing operation instructions from the outside, controlling various parameters in the laser processing process, such as laser power and processing speed; in some embodiments, the laser processing equipment also includes a gas path assembly 60 for spraying protective gas, and the main control board 431 can also be used to control the operating state of devices such as gas pumps or electromagnetic valves in the gas path assembly 60.

The power board can be used to provide power and adjust current and voltage, for example, convert the input AC power into the DC power required by the device to ensure normal operation of the device; through components such as transformers, rectifiers, and voltage stabilizers, the input voltage is adjusted to output the stable voltage, current, and power required by the device; in addition, the power board can also play a role in overcurrent, overvoltage, and short circuit protection.

[0072] In the embodiment, the main control board 431, the main control switching power supply 432, and the power board assembly 433 are arranged side by side along the arrangement direction of the air inlet 12 and the air outlet 13; this can make the overall structure compact, and the airflow can flow through the main control board 431, the main control switching power supply 432, and the power board assembly 433 to achieve good heat dissipation effect.

[0073] Please refer to Figure 5 In an embodiment, the control module 40 further includes an AC contactor assembly 44, and the AC contactor assembly 44 is arranged on the fixing frame 41 and located below the laser power supply assembly.

[0074] In the embodiment, the control module 40 further comprises an AC contactor assembly 44, which can be used to turn on and off the power supply, control the start and stop of the laser processing equipment, and make the laser processing process more efficient and stable.

The protective gas covers the processing area, for example, in the welding process, it can prevent the molten pool from contacting oxygen and nitrogen in the air, thereby preventing oxidation and pollution. In addition, the protective gas can also be used to blow away impurities and dust generated during the processing process, thereby ensuring the processing effect. Optionally, the air path assembly 60 can comprise a gas pipe, an electromagnetic valve, a gas pump and the like. The air path assembly 60 and the control module 40 are arranged on the two sides of the laser assembly 20 respectively, which realizes the separation of air and electricity, improves the space utilization rate, and facilitates the internal wiring.
