Referring to fig. 1, 2-7, and 8-13, in practical applications, the regenerated energy 1-6 outputted by the motors of the axes of the motor device are respectively shown as waveforms 71-76 shown in fig. 2-7, and the control signals 1-6 outputted during the operation time of the motors of the axes are respectively shown as waveforms 81-86 shown in fig. 8-13, that is, each control signal is respectively at a high level voltage only when the corresponding regenerated energy exists, and since the six axes of the robot arm hardly generate regenerated energy at the same time, the regenerated energy of each axis does not exist at the same time.
Referring to fig. 1, 14 and 15, the input solid-state relays 211 to 216 of the input circuit 21 are controlled by the control signals 1 to 6 to be conducted or not conducted respectively so as to switch to output the corresponding regenerated energy 1 to 6 as the input voltage shown by the waveform 91 in fig. 14, and the rectifying and filtering circuit 22 rectifies and filters the input voltage and outputs the rectified and filtered input voltage as the steady-state voltage shown by the waveform 92 in fig. 15.
It should be noted that in this embodiment, the motor is taken as an illustration to continuously operate, so that the obtained waveform 92 of the steady-state voltage is a constant dc voltage, but when the motor is intermittently operated or stopped, the waveform 92 of the steady-state voltage forms a square wave or drops to a low-level voltage.
Since the voltage used by a general motor is a large voltage, the steady-state voltage after rectification and filtering is also a large voltage, about 400 volts (Volt), while the power source terminal VCC of the subsequent circuit usually uses a lower voltage, about 24 volts, and therefore needs to be stepped down by the step-down module 3 and the voltage dividing circuit 41 for the subsequent circuit to use and determine, wherein the step-down module 3 steps down the steady-state voltage to about 24 volts, and the voltage dividing circuit 41 steps down the steady-state voltage to about 21 volts.
The judgment circuit 42 receives the judgment voltage outputted from the voltage divider circuit 41, and outputs the switching signal of the first level (about 24 volts) when the judgment voltage is higher than the high threshold voltage (about 20 volts), and outputs the switching signal of the second level (about 0 volts) when the judgment voltage is lower than the low threshold voltage (about 10 volts).
The first switching transistor 50 is turned on when the switching signal is at the first level, so as to output the switching signal of the high level voltage at the second terminal thereof, so that the second switching transistor 51 is turned on and the third switching transistor 52 is turned off, thereby outputting the regenerated voltage as the working voltage. The first switching transistor 50 is in a non-conducting state when the switching signal is at the second level, and at this time, the voltage of the control terminal of the second switching transistor 51 and the voltage of the control terminal of the third switching transistor 52 are pulled to the low level voltage through the switch steady-state resistor 500, so that the second switching transistor 51 is non-conducting and the third switching transistor 52 is conducting, and the system voltage is switched and output to be the working voltage.
Therefore, when the motor operates and outputs the regeneration energy, the regeneration energy is converted into the regeneration voltage and is output as the working voltage to be used by a peripheral circuit of the mechanical arm, and when the motor stops operating, the system voltage is switched and output as the working voltage to maintain the stable supply of the working voltage.
With reference to fig. 1, the advantages of the present embodiment can be summarized as follows through the above description:
one, through setting up this rectifier module 2, this step-down module 3, this judgement module 4 and this switch module 5, can be with this regeneration energy of square wave form, change into this steady state voltage of direct current, reduce to direct current low voltage through this step-down module 3 again, can provide this operating voltage that follow-up circuit needs, so, compare in prior art, not only can reduce a large amount of spaces that the big resistance occupied, avoid the temperature rise to influence circuit stability, can also reach energy recovery and recycle, have the efficiency of saving the electric energy.
Moreover, the switching module 5 is used for switching, so that the regeneration voltage can be output only when the regeneration energy is available, and the system voltage is still output in the rest time, thereby maintaining the stable supply of the working voltage under the condition of recovering the regeneration energy.
Second, by designing the judging circuit 42 to switch and output the switching signal of the first level or the second level when the judging voltage is higher than the high threshold voltage or lower than the low threshold voltage, the interference misjudgment caused by noises such as jitter signals can be effectively prevented, and the stability of circuit operation can be increased.
Third, by providing the first switch resistor 53, a preset voltage value at the control end of the first switch transistor 50 can be provided, so as to prevent the control end of the first switch transistor 50 from generating voltage floating due to idle connection, which causes abnormal conduction or non-conduction and generates misjudgment.
Fourth, through setting up this first switch diode 58 and this second switch diode 59, can restrict this voltage of regenerating and this system voltage for unidirectional transmission, avoid this voltage of regenerating and this system voltage to mutually irritate and lead to this operating voltage to float, cause follow-up circuit because of supplying power unstable malfunction or damage.
In conclusion, the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
