[0046] When the electronics industry produces electronic products, the generation of static electricity is a common problem, mainly through triboelectrification, electrostatic induction, etc. The harm of static electricity to the normal operation, working performance, service life, etc. of electronic products cannot be ignored. For example, electrostatic discharge (ESD, Electrostatic Discharge) may cause damage to electronic devices. The instantaneous high voltage and high current generated during electrostatic discharge may break down the insulating layer in the circuit, damage integrated circuits and microelectronic components, resulting in deterioration of device performance, decline in parameter indicators, and even burnout or failure. Another example is that static electricity can adsorb dust and debris in the air, affecting the cleanliness of electronic products. The dust and debris will adhere to the surface of electronic products, affecting the quality and reliability of the products. Another example is that electrostatic discharge will generate an electromagnetic field, causing interference to the electronic circuit and affecting the normal operation of the circuit. This interference may cause the functions of electronic instruments and devices to malfunction or misoperate. Another example is that the electric field or current generated by electrostatic discharge may generate heat, causing potential damage to components. This damage may not be easily detected, but it may gradually appear during long-term use or processing, resulting in a decline in product performance or failure.

[0047] Currently, there are some anti-static measures. For example, operators wear anti-static wristbands and turn on other anti-static devices (such as ion fans). However, during actual operations, operators may forget or be reluctant to wear anti-static wristbands or turn on ion fans, resulting in the failure of anti-static measures.

[0048] Based on this, an anti-static linkage device is proposed in an embodiment of the present application. The device receives a detection signal representing the wearing state of the anti-static wristband. When the detection signal represents that the anti-static wristband is successfully worn, the linkage monitoring device is in a preset state. When the detection signal represents that the anti-static wristband is not worn, the linkage monitoring device is in a non-preset state. In this way, it is possible to determine whether the operator has successfully worn the anti-static wristband by whether the monitoring device is in the preset state, facilitating timely understanding of the situation of the operator wearing the anti-static wristband and achieving the monitoring effect.

[0049] For ease of understanding, Figure 1 a static electricity prevention linkage system related to an embodiment of the present application is shown. As Figure 1 shown, the static electricity prevention linkage system 100 may include a detection module 110, a static electricity prevention linkage device 120 of the embodiment of the present application, and a monitoring device 130.

[0050] The detection module 110 may be used to detect whether the static electricity prevention bracelet is successfully worn, that is, to detect the wearing state of the static electricity prevention bracelet. The detection module 110 may also be used to output a detection signal characterizing the wearing state of the static electricity prevention bracelet after detecting the wearing state of the static electricity prevention bracelet.

[0051] In one example, the detection module 110 may include a control unit. After detecting that the static electricity prevention bracelet is successfully worn, the control unit controls the output of a third voltage signal. The voltage of the third voltage signal is the third voltage, for example, 3V. After detecting that the static electricity prevention bracelet is not successfully worn, the control unit does not control the output of a voltage signal or controls the output of a fourth voltage signal. The voltage of the fourth voltage signal is the fourth voltage, for example, 0V.

[0052] In one example, the detection module 110 is an external module independent of the static electricity prevention bracelet. The detection module 110 may be connected to the static electricity prevention bracelet. For example, the input end of the detection module is connected to the signal line of the static electricity prevention bracelet, and the ground end of the detection module is connected to the ground wire of the static electricity prevention bracelet. When the signal line and the ground wire of the static electricity prevention bracelet are conducted through the human body, at this time, the detection module 110 can detect the conduction signal, indicating that the static electricity prevention bracelet is successfully worn. When the signal line and the ground wire of the static electricity prevention bracelet are not conducted through the human body, at this time, the detection module 110 cannot detect the conduction signal, indicating that the static electricity prevention bracelet is not successfully worn.

[0053] In another example, the detection module 110 may be a part of the static electricity prevention bracelet. For example, the detection module 110 is an infrared induction module. When the bracelet is correctly worn on the human body, the infrared radiation of the human body will be detected by the infrared induction module, and at this time, the infrared induction module outputs a third voltage signal. When the bracelet is not correctly worn on the human body, the infrared induction module does not output a voltage signal or outputs a fourth voltage signal.

[0054] The static electricity prevention linkage device 120 may be used to receive the detection signal output by the detection module 110. When receiving the detection signal characterizing that the static electricity prevention bracelet is successfully worn, it links the connected monitoring device to be in a preset state. When not receiving a voltage signal or receiving a detection signal characterizing that the static electricity prevention bracelet is not successfully worn, it links the connected monitoring device to be in a non-preset state.

[0055] In one example, the anti-static linkage device 120 is connected to a power supply, and the power supply can input electrical energy to the anti-static linkage device 120. This electrical energy can be alternating current, and the voltage of the alternating current can be, for example, 220V. When the anti-static linkage device 120 receives a third voltage signal indicating that the anti-static bracelet has been successfully worn, through the control of the anti-static linkage device 120, the voltage input by the power supply can be input to the monitoring device 130 connected thereto, so that the monitoring device 130 is in a preset state. When no voltage signal is received or a fourth voltage signal indicating that the anti-static bracelet has not been successfully worn is received, the monitoring device 130 connected thereto is in a non-preset state. By determining whether the monitoring device 130 is in a preset state, it can be determined whether the operator has successfully worn the anti-static bracelet, which is convenient for timely understanding the situation of the operator wearing the anti-static bracelet and achieving the monitoring effect.

[0056] In one example, the monitoring device being in a preset state can be that the monitoring device is in a powered-on state, that is, a normal working state; the monitoring device being in a non-preset state can be that the monitoring device is in a powered-off state.

[0057] In one example, the monitoring device 130 can be an image acquisition device. In this example, the image acquisition device can be deployed at each work station. After the anti-static bracelet is successfully worn, the anti-static linkage device 120 controls the image acquisition device to be powered on, and the image acquisition device can send online information to the server. After the anti-static bracelet is not successfully worn, the anti-static linkage device 120 controls the image acquisition device to be powered off, and the image acquisition device will not send online information to the server. In this way, it is convenient to further verify whether there is an operator working at the work station where the online information is not sent, so as to timely remind the operator to wear the anti-static bracelet.

[0058] In another example, the monitoring device 130 can also be a lighting lamp, such as a fluorescent lamp. In this example, lighting lamps can be deployed at each work station. After the anti-static bracelet is successfully worn, the anti-static linkage device 120 controls the lighting lamp to be powered on, and the lighting lamp will enter the lit state. After the anti-static bracelet is not successfully worn, the anti-static linkage device 120 controls the lighting lamp to be powered off, and the lighting lamp will enter the extinguished state. In this way, it is convenient to further verify whether there is an operator working at the work station where the lighting lamp is in the extinguished state, so as to timely remind the operator to wear the anti-static bracelet.

[0059] In another example, the monitoring device being in a preset state can be that the lighting lamp is in a green light state; the monitoring device being in a non-preset state can be that the lighting lamp is in a red light state. After the anti-static bracelet is successfully worn, the anti-static linkage device 120 outputs a control signal to control the lighting lamp to be in the green light state. After the anti-static bracelet is not successfully worn, the anti-static linkage device 120 outputs a control signal to control the lighting lamp to be in the red light state.

[0060] Figure 2 Schematically shows the anti-static linkage device provided by the embodiment of the present application. As Figure 2 shown, the anti-static linkage device 120 may include a switch assembly 121. The switch assembly 121 is connected between the power supply and the monitoring device 130. The switch assembly 121 is used to receive a detection signal characterizing the wearing state of the anti-static bracelet. The switch assembly 121 conducts when the detection signal characterizes that the anti-static bracelet is worn, so that the monitoring device 130 is in a preset state, and disconnects when the detection signal characterizes that the anti-static bracelet is not worn, so that the monitoring device 130 is in a non-preset state.

[0061] The anti-static linkage device of the embodiment of the present application can determine whether the operator has successfully worn the anti-static bracelet by monitoring whether the monitoring device is in a preset state, which is convenient for timely understanding the situation of the operator wearing the anti-static bracelet and achieves the monitoring effect. When the operator removes the anti-static bracelet, it can also be linked in time to control the monitoring device to be in a non-preset state, and the situation that the operator privately removes the bracelet can be monitored. In addition, when the operator normally leaves the work station and needs to remove the anti-static bracelet, the anti-static linkage device of the embodiment of the present application can also control the monitoring device to power off in time, which is more energy-saving.

[0062] In some embodiments, the switch assembly 121 may include a first switch 122. The first switch 122 can be used to receive a detection signal characterizing the wearing state of the anti-static bracelet, conduct when the detection signal characterizes that the anti-static bracelet is worn, so that the monitoring device is in a preset state; and disconnect when the detection signal characterizes that the anti-static bracelet is not worn, so that the monitoring device is in a non-preset state.

[0063] In one example, as Figure 3 shown, the first end of the first switch 122 is connected to the positive pole of the power supply, the second end of the first switch 122 is connected to the first end of the monitoring device 130, and the second end of the monitoring device 130 is connected to the negative pole of the power supply. The control end of the first switch 122 is connected to the output end of the detection module 110.

[0064] In one example, the control end of the first switch 122 can be used to receive a third voltage signal output by the detection module 110 characterizing that the anti-static bracelet is worn, and control the first switch 122 to conduct according to the third voltage signal. The control end of the first switch 122 can also be used to receive a fourth voltage signal output by the detection module 110 characterizing that the anti-static bracelet is not worn, and control the first switch 122 to disconnect according to the fourth voltage signal. The control end of the first switch 122 can also be used to control the first switch 122 to disconnect when no voltage signal output by the detection module 110 is received.

[0065] The first switch 122 in this embodiment can be used to control whether the monitoring device 130 is in a preset state. When the first switch 122 is turned on, the monitoring device 130 is in the preset state. When the first switch 122 is turned off, the monitoring device 130 is in a non-preset state.

[0066] The first switch 122 in this embodiment is a switch with a control terminal. The type of the first switch 122 can be determined according to the detection signal output by the detection module 110. For example, it can be determined according to the magnitude of the voltage of the detection signal.

[0067] In one example, the first switch 122 can be a first relay. The pulling-in voltage of the first relay is less than or equal to the third voltage of the detection signal when the anti-static wristband is worn. For example, when the third voltage output by the detection module 110 is 3V, the first switch 122 can be a solid-state relay. In another example, when the third voltage output by the detection module 110 is 24V, the first switch 122 can be an intermediate relay.

[0068] In some embodiments, the working voltage of the monitoring device 130 is usually relatively large (such as 220V), and the voltage output by the detection module 110 when the anti-static wristband is worn is relatively small (such as 3V). If Figure 3 the anti-static linkage device is used to control the conduction of the larger-voltage output circuit with a smaller-voltage signal, it may damage the first switch 122. Therefore, in this embodiment, as Figure 4 shown, the switch assembly may further include a second switch 123. When the first switch 122 is turned on, the voltage at the control terminal of the second switch 123 is the first voltage. The second switch 123 is turned on at the first voltage to make the monitoring device 130 in the preset state; the second switch 123 is turned off when the first switch 122 is turned off to make the monitoring device 130 in the non-preset state. Among them, the first voltage is greater than the third voltage of the detection signal when the anti-static wristband is worn.

[0069] In some embodiments, the first voltage at the control terminal of the second switch can be directly provided by a power supply of the first voltage, or can be provided by a voltage conversion module. In this embodiment, the anti-static linkage device 120 may further include a voltage conversion module 124. The voltage conversion module 124 is connected between the power supply and the first switch 122 and is used to convert the second voltage input by the power supply into the first voltage; wherein, the second voltage is greater than the first voltage. That is to say, the voltage conversion module 124 in this embodiment can achieve a step-down function.

[0070] In one example, as Figure 5As shown, the module that provides the first voltage can be the voltage conversion module 124. The voltage conversion module 124 is connected between the positive pole of the power supply and the first end of the first switch 122. The control end of the first switch 122 is used to receive the detection signal characterizing the wearing state of the anti-static bracelet. The second end of the first switch 122 is connected to the control end of the second switch 123. The first end of the second switch 123 is connected to the positive pole of the power supply, and the second end of the second switch 123 is connected to the first end of the monitoring device 130.

[0071] In this example, when the detection signal indicating that the anti-static bracelet is worn is received at the control end of the first switch, the first end and the second end of the first switch 122 are turned on, and the first voltage output by the voltage conversion module 124 is input to the control end of the second switch 123. The first end and the second end of the second switch 123 are turned on, so that the monitoring device 130 is in a preset state. When the detection signal is not received at the control end of the first switch or the detection signal indicating that the anti-static bracelet is not worn is received, the first end and the second end of the first switch 122 are disconnected, and the first voltage output by the voltage conversion module 124 will not be input to the control end of the second switch 123. The first end and the second end of the second switch 123 are disconnected, so that the monitoring device 130 is in a non-preset state.

[0072] The voltage conversion module 124 can be, for example, a switching power supply, which can convert the alternating current input by the power supply into direct current, so as to provide direct current power.

[0073] In this embodiment, the first voltage is output by the voltage conversion module 124 and output via the second end of the first switch 122 as the control signal of the second switch 123. In this way, when the first voltage signal is used to control the conduction of the larger voltage output circuit, the damage to the switch can be reduced.

[0074] In one example, the second switch 123 can be a second relay. The pull-in voltage of the second relay is less than or equal to the first voltage, and the first voltage is greater than the third voltage of the detection signal when the anti-static bracelet is worn. The first voltage can be, for example, 24V, and the second relay can be, for example, an intermediate relay.

[0075] The anti-static linkage device of this embodiment can provide electrical energy of the second voltage for the monitoring device to support the monitoring device with the working voltage of the second voltage.

[0076] In some embodiments, such as Figure 6As shown, the second switch 123 may have a third terminal and a fourth terminal. The third terminal of the second switch 123 is connected to the second terminal of the monitoring device 130, and the fourth terminal of the second switch 123 is connected to the negative pole of the power supply. That is to say, the second terminal of the monitoring device 130 is connected to the negative pole of the power supply through the second switch 123.

[0077] In this embodiment, when the control terminal of the first switch receives a detection signal that the anti-static bracelet is worn, the first terminal and the second terminal of the first switch 122 are conducted, and the first voltage output by the voltage conversion module 124 is input to the control terminal of the second switch 123. The first terminal and the second terminal of the second switch 123, and the third terminal and the fourth terminal of the second switch 123 are conducted, so that the monitoring device 130 is in a preset state. When the control terminal of the first switch 122 does not receive a detection signal or receives a detection signal that the anti-static bracelet is not worn, the first terminal and the second terminal of the first switch 122 are disconnected, and the first voltage output by the voltage conversion module 124 will not be input to the control terminal of the second switch 123. The first terminal and the second terminal of the second switch 123, and the third terminal and the fourth terminal of the second switch 123 are disconnected, so that the monitoring device 130 is in a non-preset state.

[0078] In some embodiments, the switch assembly 121 may also be connected to an anti-static device other than the anti-static bracelet. When the switch assembly 121 is conducted, the anti-static device is in a preset state. When the switch assembly 121 is disconnected, the anti-static device is in a non-preset state.

[0079] In one example, the anti-static device may be connected in parallel with the monitoring device. For example, the second terminal of the second switch 123 of the anti-static linkage device 120 may also be connected to the first terminal of the anti-static device, and the second terminal of the anti-static device is connected to the negative pole of the power supply. The anti-static device may be, for example, an ion fan.

[0080] The anti-static linkage device of this embodiment can provide electrical energy of a second voltage for the anti-static device to support the anti-static device with a working voltage of the second voltage.

[0081] In some other embodiments, the anti-static linkage device 120 can simultaneously provide electrical energy of the second voltage and the first voltage. The second terminal of the first switch 122 in the switch assembly 121 may also be connected to other devices, and the second terminal of the other device is connected to the negative pole of the power supply. In this embodiment, the first switch 122 can also be used to control whether other devices with a working voltage of the first voltage are in a preset state.

[0082] The other device may be an anti-static device, a monitoring device, or a device with other functions.

[0083] Figure 7 schematically shows its circuit schematic diagram. As Figure 7 shown, the voltage across U2 and U3 is the second voltage, and the voltage across U1 and U3 is the first voltage. When the first switch 122 is turned on, electrical energy of the first voltage can be provided for other devices, and other devices with the operating voltage of the first voltage are controlled to be in a preset state. When the first switch 122 is turned off, other devices with the operating voltage of the first voltage are controlled to be in a non-preset state.

[0084] In one example, the first voltage can be, for example, 24V, and the second voltage can be, for example, 220V.

[0085] In one example, a 220V fluorescent lamp can be connected across U2 and U3, and a 24V DC anti-static device can be connected across U1 and U3.

[0086] The anti-static linkage device of this embodiment can provide electrical energy of the second voltage and / or the first voltage to support devices with the operating voltage of the second voltage and / or the first voltage. In this way, when the anti-static bracelet is successfully worn, load devices with different operating voltages can be simultaneously linked, which is more flexible. And when multiple devices are linked simultaneously, the manual operation of the operator can be reduced, improving work efficiency.

[0087] In some embodiments, each component in the anti-static linkage device 120 can be encapsulated together, adopting a modular design, which can save 70% of the setup time, is conducive to maintenance and storage, and is convenient for repeated use. In this embodiment, the anti-static linkage device 120 can include a power supply terminal, an input terminal, and an output terminal. The input terminal is connected to the output terminal of the detection device, and the control terminal of the switch assembly 121 in the anti-static linkage device 120 is connected to the input terminal.

[0089] Figure 8 shows the structure of an anti-static linkage device provided by an embodiment of the present application. As Figure 8As shown in the figure, the anti-static linkage device 120 may include an input end (IN1 end and IN2 end), a power supply end IN, a first output end OUT1, a second output end OUT2, a third output end OUT3, and a fourth output end OUT4. Among them, the power supply end IN is connected to a power supply and is used to receive an AC voltage of 220V. The IN1 end is connected to the first output end of the detection module 110, and the IN2 port is connected to the second output end of the detection device 110. The detection signals output by the detection module 110 are received through the IN1 end and the IN2 end. The first output end OUT1, the second output end OUT2, the third output end OUT3, and the fourth output end OUT4 can all be connected to a monitoring device or an anti-static device. The first output end OUT1, the second output end OUT2, and the third output end OUT3 can be used to connect devices with a second voltage as the operating voltage. The fourth output end OUT4 can be used to connect devices with a first voltage as the operating voltage.

[0090] Figure 9 The internal structure of an anti-static linkage device provided by an embodiment of the present application is shown. As Figure 9 shown, the anti-static linkage device 120 may include a first switch 122, a second switch 123, and a voltage conversion module 124.

[0091] An exemplary connection diagram of the internal circuit of an anti-static linkage device is also provided in an embodiment of the present application. As Figure 10 shown, the first switch 122 has two control ends, namely a first control end C1 and a second control end C2. Inside the anti-static linkage device 120, the IN1 port is connected to the first control end C1 of the first switch 122, and the IN2 port is connected to the second control end C2 of the first switch 122. When the detection module 110 detects that the anti-static bracelet is successfully worn, a third voltage signal is input through the IN1 port and the IN2 port. Under the control of the third voltage signal, the first switch 122 conducts the first end D1 and the second end D2 of the first switch 122. In this way, the current output by the voltage conversion module 124 flows through the first end D1 of the first switch 122 and then through the second end D2 into the second switch 123. The second switch 123 has two control ends, namely a third control end C3 and a fourth control end C4. When the current flows from the second end D2 into the third control end C3, the third control end C3 and the fourth control end C4 of the second switch 123 are conducted, so that the first end D3 and the second end D4 of the second switch 123 are conducted, and the third end D5 and the fourth end D6 of the second switch 123 are conducted. At this time, the power supply current flows from the live wire L into the output end U2 through the second end D4 of the second switch 123, returns to the third end D5 of the second switch 123 through the monitoring device (such as a fluorescent lamp) connected between the port U2 and the port U3 of the output end OUT3 and then flows back to the neutral wire N through the fourth end D6.

[0092] In another example, an output terminal OUT2 can also be added between the second terminal D4 and the third terminal D5 of the second switch 123, and an output terminal OUT1 can also be added ( Figure 10 not shown in

[0093] In another example, the second terminal D2 of the first switch 122 can also be directly connected to the port U1 of the output terminal OUT4 to generate direct current of the first voltage at the output terminal OUT4.

[0094] In some embodiments, the output terminal of the anti-static linkage device of the embodiments of the present application can also be connected to a device necessary for an operator to perform operations, such as an electric screwdriver. In this way, when the operator fails to wear the anti-static bracelet successfully, the anti-static linkage device will not control the electric screwdriver to be powered on, and the operator will not be able to work, thus further playing a reminder role.

[0095] The embodiments of the present application also provide an anti-static linkage system, including the anti-static linkage device 120 described in any one of the foregoing embodiments and a monitoring device 130 connected to the output terminal of the anti-static linkage device 120.

[0096] The anti-static linkage device 120 can be used to receive a detection signal characterizing the wearing state of the anti-static bracelet, and when the detection signal characterizes that the anti-static bracelet is worn, link the monitoring device 130 to be in a preset state, and when the detection signal characterizes that the anti-static bracelet is not worn, link the monitoring device to be in a non-preset state.

[0097] Optionally, the anti-static linkage system can also include a detection device 110. The output terminal of the detection device 110 is connected to the anti-static linkage device 120. The detection device 110 is used to detect the wearing state of the anti-static bracelet and output a detection signal characterizing the wearing state of the anti-static bracelet to the anti-static linkage device 120.

[0098] Optionally, the monitoring device 130 can be a lighting lamp. The monitoring device 130 being in the preset state means the lighting lamp is in the lit state, used to indicate that the anti-static bracelet is worn. The monitoring device 130 being in the non-preset state means the lighting lamp is in the extinguished state, used to indicate that the anti-static bracelet is not worn.

[0099] In this embodiment, the system can also include other anti-static devices in addition to the anti-static bracelet.

[0100] In this embodiment, when the detection module 110 is independent of the anti-static bracelet, the system can also include the anti-static bracelet.

Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
