Background technology
Laser applied in welding field it is more and more extensive, due to welding need higher peak power, therefore, before
Major part uses the YAG bonding machines of lamp pumping.But YAG bonding machines have critical defect, because conversion efficiency is too low so that
The energy consumption of machine is very high, while substantial amounts of heat needs to use cooling-water machine to eliminate, and this causes machine to become abnormal huge again, accounts for
With very big area.
In recent years, optical fiber laser started largely to come into operation, and it has a high conversion efficiency, without water in the case of small-power
The advantage such as cold, but because peak power is not high enough, metal welding field is not used for always.But with the appearance of QCW lasers, light
Fibre laser is gradually spread out in metal welding field.QCW optical fiber lasers can operate at continuous and pulse both of which, even
Under Discontinuous Conduction mode, power is relatively low, but in the pulsing mode, can export the pulse for decupling mean power, and this allows for such sharp
Light device can be widely used in metal welding field, substitute high energy consumption and bulky pulsed YAG laser.
At present, QCW optical fiber lasers have been widely applied in welding above, but existing laser is in use on the market
Some problems are still suffered from, such as, environment temperature is required, it is necessary to worked in the environment more than 10 degree, functions of the equipments lack
Network savvy, can not be with the equipment real-time, interactive data in factory, and under QCW patterns, when electric current is less than 10%, output energy is not
The problems such as stable.
The content of the invention
The purpose of this utility model provides a kind of adaptation environment temperature to overcome the above-mentioned problems of the prior art
Scope is wide, and power regulating range is big, can access the QCW optical fiber lasers of shop equipment feedback machining information.
To achieve the above object, a kind of QCW optical fiber lasers designed by the utility model, including dc source, laser
Transmitter module, it is characterized in that, in addition to temperature sensor, heater, refrigerator and FPGA control panels, and the temperature passes
Sensor, heater, refrigerator are arranged inside laser emitting module, and output end and the FPGA control panels of the temperature sensor connect
Connect, the output end of the FPGA control panels is connected with the control terminal of heater and refrigerator.
Further, the FPGA control panels are provided with CAN interface, and the CAN interface is set with factory process
Standby connection, for factory process equipment communication.
Further, the FPGA control panels are provided with feedback of status port, connect with the I/O mouths of laser process equipment
Connect, for Transmission Fibers laser works state.
Further, the refrigerator is semiconductor cooler, and semiconductor cooler has noiseless, without friction, no
Need refrigerant, small volume, it is in light weight the features such as, and reliable operation is easy to operate, is easy to carry out cold regulation.
Further, the FPGA control panels are provided with mode conversion switch.
The utility model requires higher for laser to environment temperature, it is necessary to the work in 10 to 35 degrees Celsius of environment
Make, functions of the equipments lack network savvy, can not be with the equipment real-time, interactive data in factory, and under QCW patterns, electric current is less than
When 10%, the problems such as energy is unstable is exported, proposes a kind of QCW optical fiber lasers, ambient temperature range is wide with adapting to, power
Adjustable range is big, can access the characteristics of shop equipment feeds back machining information.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
It is structured flowchart of the present utility model as shown in Figure 1, a kind of QCW optical fiber lasers of the utility model include direct current
Source 1, laser emitting module 2, temperature sensor 3, heater 4, refrigerator 5 and FPGA control panels 6.Wherein, temperature sensor 3,
Heater 4, refrigerator 5 are arranged inside laser emitting module 2.The output end of temperature sensor 3 is connected with FPGA control panels 6,
The output end of FPGA control panels 6 is connected with the control terminal of heater 4 and refrigerator 5.Refrigerator 5 is semiconductor cooler.Heating
Device 4 is resistance heater.
FPGA control panels 6 are provided with CAN interface 6-1, galvanometer control card 6-2, mode conversion switch 6-3.Wherein CAN
EBI 6-1 is connected with factory process equipment, for factory process equipment communication.Galvanometer control card 6-2 and factory process
The I/O mouths connection of equipment, transmits laser status signal.Mode conversion switch 6-3 is used for the mode of operation for adjusting laser.
When QCW optical fiber lasers work, after device power-up, temperature sensor 3 detects that environment temperature is less than 10 degree, optical fiber
Laser can not light extraction, start heater 4, when machine temperature is increased to more than 10 degree, heater 4 is stopped, simultaneously
Extraneous control circuit is informed by galvanometer control card 6-2 feedback of status interface, optical fiber laser can normal light extraction.Light
In fibre laser course of normal operation, start refrigerator 5 and work.When 10% of the demarcation peak power less than optical fiber laser
When, the mode of operation of laser is switched to continuous mode automatically, so, so that it may avoid the alarm problem of low peak power.
Feedback of status interface on galvanometer control card 6-2, when laser breaks down, temperature is below or above limiting temperature
When scope, pattern switching are not yet completed etc. not allow the situation of light extraction, this interface output low level, and force external control devices
Light extraction is controlled using this status information.
