[0031] Figure 1 and Figure 2 is a structural schematic block diagram of the power distribution control circuit in one embodiment.

[0032] In the present embodiment, as shown in Figure 1 and Figure 2 , the power distribution control circuit includes a power supply switch unit 10, a delay power-on unit 20, a remote switch unit 30, a circuit breaker protection unit 40, and a thermal cutout switch unit 50.

[0033] The power supply switch unit 10 includes a power distribution receiving end, a first load power supply end, and a second load power supply end. The power distribution receiving end is connected to the output end of the power supply source. The first load power supply end is connected to the cooling unit.

[0034] The power supply switch unit 10 can be a functional unit connected to the power supply source, the cooling unit, and the thermal cutout switch unit 50, for receiving the power supply signal output by the power supply source, and forming a path between the power supply source and the cooling unit to power the cooling unit according to the power supply signal, and forming a path between the power supply source and the thermal cutout switch unit 50 according to the power supply signal. The power distribution receiving end is used to receive the power supply signal output by the power supply source. The first load power supply end is used to output the power supply signal output via the power supply switch unit 10 to the cooling unit. The second load power supply end is used to output the power supply signal output via the power supply switch unit 10 to the thermal cutout switch unit 50. Optionally, the power supply switch unit 10 can be a control structure including a plurality of parallel electromagnetic relays.

[0035] The delayed power-on unit 20 includes a signal receiving end and a delayed signal output end. The signal receiving end is connected to the first load power supply end, and the delayed signal output end is connected to the laser. The cooling unit starts earlier than the laser power distribution.

[0036] The delayed power-on unit 20 can be connected to the power supply switch unit 10 and the laser, and is used to receive the power signal output by the power supply switch unit 10, generate a delayed signal according to the power signal after a preset delay is met, and form a path between the power supply, the power supply switch unit 10 and the laser according to the delayed signal to distribute power to the laser.

Optionally, the delayed power-on unit 20 can be a control structure including a time relay.

[0037] The power supply outputs a power signal through its output terminal. This power signal enters the power supply switching unit 10 via the power distribution receiving terminal of the power supply switching unit 10. The power signal also enters the cooling unit (such as a chiller) via the first load power supply terminal of the power supply switching unit 10 connected to the cooling unit, thus forming a path between the power supply and the cooling unit for power distribution to the cooling unit. The power signal enters the delay power-on unit 20 via the signal receiving terminal of the delay power-on unit 20 connected to the first load power supply terminal of the power supply switching unit 10. After satisfying the preset delay, a delay signal is generated. Then, the delay signal enters the laser via the delay signal output terminal of the delay power-on unit 20 connected to the laser, thus forming a path between the power supply and the laser for power distribution to the laser. This allows the cooling unit to start power distribution earlier than the laser to achieve pre-processing (such as preheating) of the cooling unit. After the cooling unit reaches a certain temperature, the laser then performs laser processing, which can achieve protective startup of the laser.

[0038] The remote switching unit 30 includes a first power receiving end and a power supply control end.

The second power receiving terminal is used to receive the power signal output by the power supply, and the circuit breaker control terminal is used to output the circuit breaker control signal generated according to the power signal to the power supply switch unit 10.

[0043] By adding an additional circuit breaker protection unit 40 between the power supply and the power supply switch unit 10, short-circuit overload and leakage protection can be achieved during power distribution.

[0054] The power distribution control circuit, power distribution control device, and processing equipment provided in the above embodiments have the following characteristics: the power supply outputs a power signal through its output terminal. The power signal enters the power supply switching unit through the power distribution receiving terminal of the power supply switching unit. The power signal enters the cooling unit (such as a chiller) through the first load power supply terminal of the power supply switching unit connected to the cooling unit, thereby forming a path between the power supply and the cooling unit to distribute power to the cooling unit. The power signal enters the delayed power-on unit through the signal receiving terminal of the delayed power-on unit connected to the first load power supply terminal of the power supply switching unit. After satisfying the preset delay, a delayed signal is generated. Then, the delayed signal enters the laser through the delayed signal output terminal of the delayed power-on unit connected to the laser, thereby forming a path between the power supply and the laser to distribute power to the laser. This enables the cooling unit to start power distribution earlier than the laser, thus achieving pre-processing of the cooling unit.
