Static elimination device

The present invention provides a static elimination device, especially a static elimination device for quickly switching power supplies.

When a manufacturing factory manufactures a new product, it usually generates static electricity during the manufacturing process, causing the new product to absorb the static electricity and affect its appearance or be damaged by electrostatic attacks. Therefore, most of the factory will be equipped with a static elimination device to generate positive and negative ions, and release positive and negative ions at the tip of the static elimination device, thereby neutralizing static electricity on the new product, thus avoiding new products being affected by static electricity. The appearance is damaged by an electrostatic attack.

For example, when a plastic bag manufacturing factory manufactures a new plastic bag, because of the characteristics of the plastic, the plastic bag can easily absorb static electricity on the production line (such as a conveyor belt). At this time, if the worker accidentally smashes the plastic bag. Or after the concave fold, the plastic bag will be covered with many creases, and it will not be smoothed and restored to its original state. Therefore, the static elimination host removes static electricity on the plastic bag, thereby keeping the newly manufactured plastic bag flat and easy to stack flat.

However, after the static elimination device is powered by high voltage for a long time, high voltage electric lines will be generated on the pipeline, which will cause the insulator to start to fall. If the working environment is exposed to high temperature, humidity, pH, dust accumulation, etc., the insulator will be damaged. The rupture causes the high voltage electricity to leak. When the high-voltage electricity leaks, it will cause sparks, which may cause fire, explosion, electric shock, ignition of flammable materials and many other safety problems, endangering the safety of life and property.

There is a solution in the workshop to detect whether a large current flows through the fuse. If a large current flows, the fuse will be blown, thereby forming an open circuit, so that the high voltage cannot be continuously discharged, thereby avoiding the continuous spark generation. And caused a fire. However, this method requires time to wait for the fuse to be blown to achieve the effect of breaking, that is, the process of waiting for the fuse to blow is likely to have a fire, and therefore the way of using the fuse still has problems affecting the safety of the work, and endangering the safety of life and property.

In view of the above problems, the present invention provides a static elimination device that enables a power supply to be continuously outputted in an abnormal state through rapid switching, thereby preventing a disaster from expanding, thereby preserving life and property safety, and maintaining a work safety environment.

An embodiment of the present invention provides an electrostatic elimination device, including: an input module, a transformer circuit, a static elimination unit, a switching module, and a control module. The input module is used to receive the mains power. The transformer circuit is electrically connected to the input module, and converts the mains power supply into an operating power source. The static elimination unit is powered by the operating power source to eliminate external static electricity. The switching module is connected between the input module and the transformer circuit, and the switching module selectively conducts the mains power to the transformer circuit. The control module is coupled between the input module and the switching module. When the utility power exceeds a rated voltage, the control module generates a shutdown command to the switching module, so that an open circuit is formed between the input module and the transformer circuit.

The static elimination device formed by the above structure monitors the mains power supply through the control module, and when the power supply exceeds the rated voltage, the control module causes the switching module to form an open circuit, thereby quickly forming an open circuit between the input module and the transformer circuit. In order to avoid the continuous output current of the input module to the transformer circuit, it is also necessary to avoid the continuous spark generation, thereby avoiding the occurrence of fire, thereby preserving the safety of life and property, and maintaining the safety environment.

FIG. 1 is a schematic structural view of a static elimination device 1 according to an embodiment of the present invention. FIG. 2 is a schematic plan view showing the appearance of the static elimination device 1 according to an embodiment of the present invention. FIG. 3 is a circuit diagram of the static elimination device 1 according to an embodiment of the present invention. Referring to FIG. 1 , the static elimination device 1 includes an input module 20 , a transformer circuit 30 , a static elimination unit 40 , a switching module 50 , and a control module 10 . The control module 10 is electrically connected to the input module 20 , and the switching module 50 is electrically connected between the input module 20 and the transformer circuit 30 , and the static elimination unit 40 is electrically connected to the transformer circuit 30 .

The input module 20 includes a mains receiving port 21 for receiving a mains power supply AC, wherein the mains power supply AC is in an alternating current mode.

The transformer circuit 30 converts the commercial power source AC to the operating power source AC' for operation of the static electricity eliminating unit 40. The transformer circuit 30 is configured to increase the voltage value of the commercial power source AC to form the operating power source AC', that is, the voltage value of the operating power source AC' is greater than the voltage value of the commercial power source AC, thereby using the static electricity eliminating unit 40. Neutralize and eliminate static electricity on external components (not shown). However, the present creation is not limited thereto. In some embodiments, the transformer circuit 30 can also lower the voltage value of the commercial power source AC.

Furthermore, the transformer circuit 30 includes an output port 31 electrically connected to the static elimination unit 40. The output port 31 is for outputting the operating power source AC' to the static electricity eliminating unit 40.

The static electricity eliminating unit 40 obtains the operating power source AC' via the output port 31, and operates. After the static elimination unit 40 is operated, a plurality of positive and negative ions are generated by using a high voltage electric power, and the positive and negative ions are blown out through a plurality of tips to an external component (not shown), for example, a new product on the production line, whereby Negative ions neutralize static electricity on external components.

The switching module 50 turns on or off the electrical connection between the input module 20 and the transformer circuit 30 according to a control signal (for example, a shutdown command or an open command). In the normal state, the switching module 50 receives the opening command and responds to the opening command to make the electrical connection between the input module 20 and the transformer circuit transformer circuit 30 conductive, so that the commercial power source AC is transmitted from the input module 20 to Transformer circuit 30. When there is an abnormal state, the switching module 50 receives the shutdown command and responds to the shutdown command to cause the electrical connection between the input module 20 and the transformer circuit 30 to be in an open state, so that the commercial power source AC cannot be transmitted to the transformer circuit 30. The normal state or abnormal state is determined by the control module 10. In other words, the control signal is generated by the control module 10.

The switching module 50 further includes a switch 51. The switch 51 is in an on state in a normal state, thereby conducting the mains power supply AC to the transformer circuit 30. When the switch 51 receives the shutdown command from the control module 10, the switch 51 is switched to the open state, so that the input module 20 cannot conduct the commercial power supply AC to the transformer circuit 30.

FIG. 4 is a partial circuit schematic diagram of the control module 10 according to an embodiment of the present invention. Referring to FIGS. 1 and 4 , the control module 10 includes a voltage detecting unit 11 , and the voltage detecting unit 11 is electrically connected between the mains receiving port 21 and the control end of the switch 51 . The voltage detecting unit 11 is configured to monitor the voltage value of the commercial power source AC. When the voltage detecting unit 11 detects that the commercial power source AC exceeds the rated voltage, the voltage detecting unit 11 generates a closing command to the switch 51 to form an open circuit between the input module 20 and the transformer circuit transformer circuit 30. That is, the voltage detecting unit 11 stores a monitored value of the rated voltage, so the voltage detecting unit 11 determines whether the voltage value of the commercial power source AC is greater than the monitoring value of the rated voltage; if the voltage value of the commercial power source AC is less than the rated voltage When the value is monitored, the voltage detecting unit 11 sends a normal command to the switch 51, so that the switch 51 maintains the normal state, that is, the input module 20 and the transformer circuit 30 maintain the conduction. Conversely, if the voltage value of the commercial power supply AC is greater than or equal to the monitored value of the rated voltage, that is, the abnormal state is indicated. At this time, the voltage detecting unit 11 generates a shutdown command and transmits it to the switch 51 to cause the switch 51 to be turned into an open circuit. status. Thereby, the switch 51 is quickly switched to the open state, and the operation power supply AC' can be prevented from being continuously outputted, so that the spark can be continuously generated, thereby preventing the occurrence of a fire.

In one embodiment, referring to FIG. 4, the voltage detecting unit 11 includes a detecting resistor 111 and a determining unit 112. The determining unit 112 is coupled to the detecting resistor 111. The detecting resistor 111 is electrically connected to the mains receiving port 21 of the input module 20 to obtain the commercial power source AC and then converted into a voltage signal. The determining unit 112 is configured to determine when the voltage signal is greater than the rated voltage to generate a shutdown command.

In an embodiment, referring to FIG. 4, the determining unit 112 further includes a light emitting element 1121 and a photosensitive switch 1122. The light-emitting element 1121 is electrically connected to the detecting resistor 111. When the voltage signal after the detecting resistor 111 is converted is greater than the rated voltage, the light-emitting element 1121 emits a light source, whereby the photosensitive switch 1122 generates a close command in response to the light source. That is to say, when the potential difference between the two ends of the detecting resistor 111 exceeds the rated voltage, the light-emitting element 1121 is driven to emit a light source, thereby causing the photosensitive switch 1122 to be stimulated by the light to generate a shutdown command.

In another embodiment, referring to FIG. 4, the control module 10 further includes a transient diode 113 and a filter 114. The transient diode 113 and the filter 114 are located in the detecting resistor 111 and the determining unit 112. between. The transient diode 113 is used to resist the problem of high-voltage electrical turbulence generated in an abnormal state, so as to avoid problems such as signal instability or damage to circuit components caused by high-voltage electrical turbulence. The filter 114 is a combination of a resistor and a capacitor to block electromagnetic interference (EMI, ElectroMagnetic Interference) or electromagnetic compatibility (EMC, Electromagnetic Compatibility), causing signal instability or signal triggering abnormality. In this embodiment, the filter is a low-pass filter, and in some embodiments, the filter may be a high-pass filter or other kinds of filters, and the creation is not limited.

Referring to FIG. 1 , in an embodiment, the input module 20 further includes a voltage conversion unit 22 electrically connected to the mains receiving port 21 . The voltage conversion unit 22 obtains the commercial power source AC to be converted into the working power source, and transmits the working power source to the control module 10 for the control module 10 to operate. In this embodiment, the voltage conversion unit 22 includes an AC-DC circuit for converting the commercial power supply AC and outputting the DC power supply DC. That is to say, the voltage conversion unit 22 converts the commercial power supply AC from the AC power mode to the DC power supply power supply DC, and then supplies power to the control module 10 for the control module 10 to operate by the operating power supply. Therefore, when the operating power supply AC' is abnormal, the operating power supply is not affected, that is, when the operating power supply AC' is abnormal, the control module 10 can stably provide a shutdown command to make the switch 51 open. The state ensures that the abnormal operation power source AC' cannot be supplied to the static elimination unit 40.

Referring to FIG. 1 , the static elimination device 1 further includes an alarm module 60 electrically connected to the control module 10 , and the alarm module 60 issues an alarm message according to the shutdown command. The alarm information can be used to drive the display of text, sound, light or other alarms, etc., to prompt the user at the first time, so that the user can respond to the situation immediately and avoid the disaster.

The static electricity eliminating device 1 configured as described above monitors and determines whether or not the commercial power source AC is abnormal by the control module 10, thereby quickly passing through the switching module 50 when the commercial power source AC is supplied to the transformer circuit 30 at an abnormal time. The transformer circuit 30 cannot continuously output the operating power source AC', thereby preventing the static electricity eliminating device 1 from continuously receiving an overcurrent and forming a fire, thereby ensuring the safety of the whole life property and maintaining the safety environment.
