Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lasers, in particular to an intelligent antifreeze system for lasers. Background Art
[0002] As is known, water-cooled laser equipment is required for laser cleaning, welding and cutting. When the water-cooled laser equipment is used in winter, the water outlet of the chiller will lead water to the water inlet of the laser and the laser gun head, and finally the water will be circulated out from the water outlet to the return water outlet of the chiller. If the equipment is shut down and the power is cut off, it will stop working, and water will remain in the water pipes, lasers, and gun head pipes. Due to the low temperature in winter, the water remaining in the pipes, lasers, and galvanometer gun head pipes will freeze, which seriously affects the service life of the laser, and even damages the laser. The usual way to change the status quo is to add antifreeze, but adding antifreeze not only cannot be used for a long time, but also needs to be replaced regularly, which increases the cost of use and may corrode the equipment pipes. Therefore, in order to solve the above problems, a laser intelligent antifreeze system is proposed. Summary of the invention
[0003] In order to overcome the deficiencies in the background technology, the utility model discloses a laser intelligent antifreeze system.
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:
[0005] A laser intelligent antifreeze system comprises a galvanometer gun head, a laser, a water chiller and an external control system. The control system communicates with the water chiller, the laser and the galvanometer gun head respectively through an RS485 communication protocol. A water outlet C of the laser and a water return port of a water tank in the water chiller, and a water inlet A of the laser and a water outlet B of the water tank in the water chiller are both connected through pipelines. A solenoid valve conversion valve is arranged on the pipeline between the laser water inlet A and the water outlet B of the water tank in the water chiller. The three-way interfaces of the solenoid valve conversion valve are respectively connected with the water chiller, the laser and a dust removal air pump. A T-shaped tee A is connected on the pipeline between the solenoid valve conversion valve and the laser, and one passage of the T-shaped tee A is connected with the water inlet B of the galvanometer gun head. A T-shaped tee B is connected on the pipeline between the laser water outlet C and the water return port of the water tank in the water chiller, and one passage of the T-shaped tee B is connected with the water outlet A of the galvanometer gun head.
[0006] The laser intelligent antifreeze system is provided with a temperature detection system near the chiller. The temperature detection system is a thermocouple temperature sensor and is connected to an external control system through a signal line.
[0007] The laser intelligent antifreeze system is connected to a water pump on the pipeline at the water outlet B of the water tank.
[0008] The laser intelligent antifreeze system, the dust removal air pump and the water pump are connected to the external control system through signal lines.
[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0010] The laser intelligent antifreeze system described in the utility model is provided with a solenoid valve conversion valve. When the equipment is shut down and the temperature detection system detects that the external temperature is lower than 2°C, the temperature detection system sends a signal to the external control system. The control system shuts down the laser and the chiller through the signal, opens the solenoid valve conversion valve and the dust removal air pump, and the dust removal air pump discharges the water remaining in the pipeline, the laser, and the galvanometer gun head pipeline into the water tank, thereby effectively avoiding damage to the laser. The utility model has a simple structure and is easy to use, and the operating cost is effectively reduced. The antifreeze purpose of the laser is achieved without adding antifreeze liquid.

[0015] The laser intelligent antifreeze system described in the utility model is implemented.

Under the pressure of the gas, the water in the laser 1 enters the pipeline between the laser 1 and the water tank 8 through the water outlet C16, and is finally discharged into the water tank 8. The water in the galvanometer gun head 14 enters the T-shaped three-way B12 through the water outlet A13, and is collected with the water discharged from the laser 1 and discharged into the water tank 8, which effectively prevents When the temperature is low, the water remaining in the various pipelines, lasers, and galvanometer gun head pipes will freeze, causing damage to the laser; after the water remaining in the various pipelines, lasers, and galvanometer gun head pipes is drained into the water tank 8, the entire system enters a dormant state, and the next time it is used, it can be shut down and restarted to restore to normal use; the control system is a single-chip microcomputer, and the above control systems can all be operated on the touch screen.
