[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0056] See also Figure 1 , Figure 1 A schematic diagram of a marking device 1 provided in an embodiment of the present application. The marking device 1 can output a label (not shown), which is used to be affixed to a corresponding material to mark the material. The staff or the marking device 1 can record the relevant information of the material on the label. In this way, the staff can determine the relevant information of the material through the label, thereby determining whether the material is the material the staff is looking for.

[0057] In an embodiment of the present application, the material is a signal line connected to an electronic product. In other embodiments, the type of the material is not specifically limited. For example, the material may be, but is not limited to, a power cable, etc.

[0058] In the embodiments of the present application, the content of the related information is not specifically limited. For example, the related information may include, but is not limited to, the number of the material, the location where the material is connected, etc.

[0059] It can be understood that the material can be a plurality of signal lines connected between the detection device (not shown) and the electronic product (not shown), and the plurality of signal lines are respectively connected to a plurality of connection points on the electronic product. The label is attached to the signal line, and the recorded relevant information may include, but is not limited to, the number of the signal line, the number of the connection point corresponding to the signal line, etc.

[0060] In the embodiments of the present application, the type of the tag is not specifically limited. For example, the tag may be, but is not limited to, a label sticker, a Radio Frequency Identification (RFID) tag, or a Near Field Communication (NFC) tag.

[0061] like Figure 1 As shown, the marking device 1 may include a reminder device 100 and a label output device 200. The reminder device 100 is connected to the label output device 200 for communication. The label output device 200 is used to output a label in response to the operation of the reminder device 100 by the staff when powered on. The label output device 200 is used to drive the label to be output from the output port 201 ( Figure 2 ) is removed from the marking device 1.

[0062] In the embodiments of the present application, there is no specific limitation on the fixing method of fixed connection and fixed installation. For example, the fixing method may include, but is not limited to, screw fixing, welding fixing, etc.

[0063] In the embodiments of the present application, the communication connection method is not specifically limited. For example, the communication connection may be a wireless communication connection implemented by wireless LAN, Bluetooth, 3G, 4G, 5G and other wireless communication technologies. For another example, the communication connection may be a wired communication connection implemented by a connection device such as a data cable.

[0064] In one embodiment, the label output device 200 is used to output a blank label. The staff can stick the blank label output by the label output device 200 on a designated signal line and then record relevant information of the signal line on the blank label.

[0065] For example, the label can be a label sticker, and the label output device 200 can include a driving device (not shown in the figure), and a label paper roll (not shown in the figure) is connected to the driving end of the driving device. The driving device is used to drive the label paper roll to rotate, so that the labels that have not been torn off from the label paper roll move to the position of the output port 201, thereby realizing the output of the label by the label output device 200.

[0066] In the embodiments of the present application, the type of the driving device is not specifically limited. For example, the driving device may be, but is not limited to, a reduction motor or the like.

[0067] In another embodiment, the label output device 200 is used to output a label recording relevant information of the signal line, and the staff can complete the marking of the signal line by sticking the label output by the label output device 200 on the designated signal line.

[0068] For example, the label may be a label sticker, and the label output device 200 may include a driving device and a printing device (not shown), and a label paper roll is connected to the driving end of the driving device. The printing device is used to print the relevant information of the designated signal line on a label of the label paper roll in response to the staff's operation of the reminder device 100, and the driving device is used to drive the label paper roll to rotate so that the label printed with the relevant information moves to the position of the output port 201, thereby realizing the output of the label by the label output device 200.

[0069] It can be understood that the printing device can print the relevant information through the existing technology in the relevant field, and the embodiments of the present application will not go into details.

[0070] In some embodiments, a protective shell (not shown) may be provided on the label output device 200, and the protective shell may be movably mounted on the label output device 200 near the output port 201, and is used to shield the output port 201. When the staff needs to mark the signal line through the marking device 1, the protective shell may be driven to move manually or through a moving device on the label output device 200 to open the output port 201.

[0071] Please also read Figure 2 The marking device 1 may further include a frame 300 . The reminding device 100 and the label output device 200 may be fixedly mounted on the frame 300 .

[0072] In the embodiment of the present application, there is no specific limitation on the shape of the frame 300. For example, the frame 300 can be, but is not limited to, a material clip.

[0073] Exemplarily, the frame 300 can be a material clamp, and the label can be a label sticker. The frame 300 includes two clamping parts 301, a clamping tail part 302 and two clamping parts 303. The two clamping parts 301 are fixedly connected to the two clamping parts 303 respectively, and the two clamping parts 303 are fixedly connected to the clamping tail part 302, and the two clamping parts 303 are arranged at intervals. The clamping part 303 is made of elastic material. The staff can press the two clamping parts 303 to make the two clamping parts 303 close to each other and the two clamping parts 301 close to each other. The label output device 200 can be installed on any clamping part 301, and the output port 201 is located on the side of the clamping part 301 where the label output device 200 is located facing the other clamping part 301.

[0074] When the staff needs to mark the signal line, they can first make the signal line enter the space between the two clamping parts 301, and press the two clamping parts 303 to make the two clamping parts 301 approach each other and clamp the signal line from both sides. At this time, the position of the signal line corresponds to the position of the output port 201. Then, the label output device 200 can drive a label to be moved out of the output port 201, and the label moved out of the output port 201 can be adhered to the signal line during the movement, thereby completing the marking of the signal line.

[0075] After the signal line is marked, the staff can release the force on the clamp body 303, and the clamp body 303 can return to its original state under the action of its own elastic force, and drive the two clamping parts 301 away from each other through its own elastic force, thereby releasing the clamping of the signal line by the two clamping parts 301.

[0076] In the embodiments of the present application, the elastic material is not specifically limited. For example, the elastic material may be, but is not limited to, elastic alloy, plastic, etc.

[0077] It can be understood that the reminder device 100 can be arranged at a distance from the label output device 200. For example, the reminder device 100 can be partially arranged at the clip tail portion 302 and partially arranged at the two clip body portions 303.

[0078] In the embodiment of the present application, the reminder device 100 can display at least part of the relevant information corresponding to the signal line, and when the label output by the label output device 200 contains relevant information of the signal line, the relevant information recorded on the label corresponds to the content displayed by the reminder device 100. The staff can know the signal line that has been marked according to the information displayed on the reminder device 100, and mark another signal line in sequence.

[0079] In an embodiment of the present application, the reminder device 100 can display the decimal numerical number of the signal line. In other embodiments, the reminder device 100 can display other relevant information of the signal line.

[0080] It can be understood that the reminder device 100 can update the displayed information in response to the staff's operation of the reminder device 100, and the label output device 200 can receive information from the reminder device 100 when the staff operates the reminder device 100. The label output device 200 can output a label corresponding to the updated displayed information of the reminder device 100 based on the information received from the reminder device 100, that is, the content recorded in the label output by the label output device 200 can be adjusted based on the staff's operation of the reminder device 100.

[0081] In the embodiments of the present application, the method by which the label output device 200 adjusts the content recorded on the output label is not specifically limited. For example, when the label is a label sticker, the label output device 200 may include multiple fonts (not shown), and the label output device 200 may use the font corresponding to the information received from the reminder device 100 to print the label, and drive the printed label to move to the output port 201 through the driving device. For another example, when the label is a label sticker, the label output device 200 may include multiple label paper rolls, and the multiple label paper rolls are respectively used to accommodate label stickers with different relevant information. The label output device 200 may select the label paper roll corresponding to the received information according to the received information, and drive the selected label paper roll to rotate, so that the label that has not been torn off from the label paper roll moves to the output port 201. For another example, when the tag is an RFID tag or an NFC tag, the tag output device 200 may include an information importing component (not shown), which is an electronic component that can import information into the tag. The tag output device 200 can import relevant information corresponding to the received information into the tag based on the information received by the reminder device 100, and drive the tag that has completed the information import to move to the output port 201 through a driving device.

[0082] It is understood that the label output device 200 may include a processor (not shown). The processor is connected to the reminder device 100 for communication and is used to receive information from the reminder device 100. The processor may adjust the content recorded on the output label according to the received information.

[0083] In the embodiments of the present application, the type of processor is not specifically limited. For example, the processor may be, but is not limited to, a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the above program.

[0084] In other embodiments, the reminder device 100 may remind the staff of at least part of the relevant information corresponding to the signal line by means of an audio reminder.

[0085] See also Figure 3 , Figure 3 A schematic diagram of a reminder device 100 provided in an embodiment of the present application is shown.

[0086] In some embodiments, the reminder device 100 may include a first switch S1, a trigger unit 10, an adding unit 20, and a display unit 30. The adding unit 20 may include a first connection terminal 21, a second connection terminal 22, and a third connection terminal 23. The first switch S1 is electrically connected to the trigger unit 10. The trigger unit 10 is electrically connected to the first connection terminal 21 and the second connection terminal 22 of the adding unit 20, and one end of the trigger unit 10 away from the first switch S1 is grounded. The display unit 30 is electrically connected to the third connection terminal 23 of the adding unit 20 and is electrically connected to the label output device 200. The adding unit 20 may calculate the accumulated value, generate a numerical signal according to the accumulated value, and then output the numerical signal to the display unit 30 through the third connection terminal 23. The display unit 30 may display the accumulated value according to the numerical signal. The label output device 200 receives a signal from the display unit 30, thereby adjusting the relevant information recorded on the output label and printing and / or moving the label to achieve the output of the label corresponding to the accumulated value.

[0087] The first switch S1 can receive a first voltage, and in response to the first switch S1 being closed, output the first voltage to the trigger unit 10. The trigger unit 10 can receive the first voltage from the first switch S1, and can also receive a trigger voltage. In response to receiving the first voltage and the trigger voltage at the same time, the trigger unit 10 outputs the first voltage to the first connection terminal 21 and outputs the second voltage to the second connection terminal 22. The voltage difference between the first voltage and the second voltage is greater than a voltage threshold.

[0088] In response to the voltage difference between the first connection terminal 21 and the second connection terminal 22 being greater than a voltage threshold, the trigger unit 10 can modify the accumulated value to the sum of the original accumulated value and a preset increment, generate a numerical signal based on the accumulated value, and then output the numerical signal to the display unit 30 through the electrical connection terminal.

[0089] It is understood that each component in the reminder device 100 can obtain the power supply voltage through the same or different power supplies, and each component can be grounded separately, which is not described in detail in the embodiments of the present application. In the embodiments of the present application, the power supply source and grounding method of each component in the reminder device 100 are not specifically limited.

[0090] In the embodiment of the present application, the content of the preset increment is not specifically limited. For example, the preset increment can be, but is not limited to, 1.

[0091] It can be understood that the initial value of the accumulated value is 0, and as the number of times that the adding unit 20 simultaneously receives the first voltage and the trigger voltage increases, the accumulated value gradually increases.

[0092] In an embodiment of the present application, the accumulated value corresponds to the number of the signal line. It can be understood that the base of the value when the display unit 30 displays the accumulated value can be the same as or different from the base when the addition unit 20 calculates the accumulated value, and the embodiment of the present application does not limit this. For example, the accumulated value calculated by the addition unit 20 is binary, and the accumulated value displayed by the display unit 30 is decimal. Exemplarily, the addition unit 20 may include an 8-bit binary adder, and the initial value of the accumulated value in the addition unit 20 is 00000000; the display unit 30 may include a transistor that can display two-digit numbers, and the initial value of the accumulated value displayed by the display unit 30 is 00.

[0093] It can be understood that the trigger unit 10 can be connected to the label output device 200 and obtain the trigger voltage through the label output device 200. For example, the trigger voltage can be the power supply voltage of the label output device 200, the voltage generated by adjusting the power supply voltage of the label output voltage, the working voltage of the label output device 200, or the voltage generated by adjusting the working voltage of the label output voltage.

[0094] It can be understood that each time the first switch S1 is closed, the value displayed on the display unit 30 is adjusted, and the label output device 200 outputs a label corresponding to the number based on the number displayed on the display unit 30. By checking the display unit 30, the staff can know the number of the signal line that has been marked, and determine the next signal line to be marked according to the order of the signal line numbers. In this way, the reminder device 100 can remind the staff of the number of the signal line that has been marked and the number of the next signal line to be marked while triggering the label output device 200 to output the label, thereby reducing the possibility of the staff marking the label on the wrong signal line. When the staff connects multiple signal lines to multiple connection points on the electronic product and detects the electronic product through the detection equipment connected to the signal line, the accuracy of the staff's judgment on whether the electronic product is faulty can be improved.

[0095] In the embodiment of the present application, the installation position of the first switch S1 is not specifically limited. For example, the frame 300 may be a material clamp, and the first switch S1 may be installed on a clamp body 303 .

[0096] It can be understood that the first switch S1 is a normally open switch with a reset function. In the embodiments of the present application, the type of the first switch S1 is not specifically limited. For example, the first switch S1 can be a key switch with a reset function. When the staff presses the first switch S1, the first switch S1 is closed; after the staff releases the force on the first switch S1, the first switch S1 automatically resets and the first switch S1 is disconnected.

[0097] In some embodiments, the reminder device 100 may further include a first load R1. One end of the first load R1 is electrically connected to the end of the first switch S1 away from the trigger unit 10, and the other end may receive the first working voltage VDD1. After receiving the first working voltage VDD1, the first load R1 adjusts the first working voltage VDD1 to the first voltage and outputs the first voltage to the first switch S1.

[0098] In the embodiment of the present application, the source of the first working voltage VDD1 is not specifically limited.

[0099] It can be understood that the first load R1 can alleviate the problem of current instability in the circuit at the moment when the first switch S1 is closed, so as to improve the working stability of the reminder device 100.

[0100] In some embodiments, the reminder device 100 may further include a second load R2 and a second switch S2. One end of the second load R2 is electrically connected to the trigger unit 10, and the other end is electrically connected to the second switch S2. The end of the second switch S2 away from the second load R2 can receive the second operating voltage VDD2. When the second switch S2 is closed, the second operating voltage VDD2 is transmitted to the second load R2. After receiving the second operating voltage VDD2, the second load R2 adjusts the second operating voltage VDD2 to a trigger voltage and outputs the trigger voltage to the trigger unit 10.

[0101] Exemplarily, the second operating voltage VDD2 may be a supply voltage or an operating voltage of the label output device 200 .

[0102] It can be understood that the second load R2 can alleviate the problem of current instability in the circuit at the moment when the second switch S2 is closed, so as to improve the working stability of the reminder device 100.

[0103] It can be understood that the second switch S2 is a switch element that can maintain a normally open or normally closed state. For example, the second switch S2 can be a start switch of the label output device 200. The label output device 200 can be connected to an external power supply (not shown) through the second switch S2. When the second switch S2 is closed, the label output device 200 is powered, and the second load R2 receives the second working voltage VDD2.

[0104] It can be understood that when the second switch S2 and the first switch S1 are closed at the same time, the trigger unit 10 can receive the trigger voltage and the first voltage at the same time, and output the first voltage and the second voltage to the adding unit 20. That is, the trigger unit 10 can output the first voltage and the second voltage only when the first switch S1 and the start switch of the label output device 200 are closed at the same time. In this way, the situation that the first switch S1 is accidentally touched when the label output device 200 is not working, resulting in the reminder device 100 has displayed the accumulated value, but the label output device 200 cannot output the label corresponding to the accumulated value, can be reduced.

[0105] See also Figure 4 In some embodiments, the trigger unit 10 may include a switch tube Q and a voltage regulating load R3. The first end of the switch tube Q is connected to the first switch S1, the second end is electrically connected to the first connection terminal 21, the second connection terminal 22 and the voltage regulating load R3, and the third end is connected to the second switch S2 for receiving the trigger voltage. One end of the voltage regulating load R3 is connected to the second end of the switch tube Q and the first connection terminal 21, and the other end is connected to the second connection terminal 22, and one end of the voltage regulating load R3 connected to the second connection terminal 22 is grounded.

[0106] When the third terminal of the switch tube Q receives the trigger voltage, the switch tube Q is turned on, and the first voltage can be transmitted from the first terminal of the switch tube Q to the second terminal of the switch tube Q. The switch tube Q can output the first voltage from the second terminal to the first connection terminal 21 and the voltage regulating load R3. After receiving the first voltage, the voltage regulating load R3 can adjust the first voltage to a second voltage, wherein the second voltage is less than the first voltage. The voltage regulating load R3 can output the second voltage to the second connection terminal 22. In this way, a voltage difference is generated between the first connection terminal 21 and the second connection terminal 22, and the voltage difference can be equal to or nearly equal to the voltage difference between the first voltage and the second voltage, and the voltage difference is greater than the voltage threshold.

[0107] In the embodiments of the present application, there is no specific limitation on the type of the switch tube Q. For example, the switch tube Q may be, but is not limited to, a triode, a field effect tube, etc. Exemplarily, the switch tube Q may be a PNP type triode, the first end of the switch tube Q is the emitter of the triode, the second end of the switch tube Q is the collector of the triode, and the third end of the switch tube Q is the base of the triode.

[0108] It can be understood that the trigger voltage can trigger the switch tube Q to turn on, and the closing of the first switch S1 can enable the switch tube Q to receive the first voltage and output the first voltage through the second terminal. In this way, the switch tube Q can output the first voltage only when receiving the first voltage and the trigger voltage, so that the trigger unit 10 outputs the first voltage and the second voltage.

[0109] In the embodiment of the present application, the types of the first load R1, the second load R2 and the voltage regulating load R3 are not specifically limited. For example, the first load R1, the second load R2 and the voltage regulating load R3 can all be resistors.

[0110] In some embodiments, the adding unit 20 may include an adding module 24 and a latch module 25. The first connection terminal 21 and the second connection terminal 22 of the adding unit 20 may be connection terminals of the adding module 24. The third connection terminal 23 of the adding unit 20 is a connection terminal of the latch module 25. An output terminal of the adding module 24 is electrically connected to an input terminal of the latch module 25. The latch module 25 may be electrically connected to an input terminal of the adding module 24 through the third connection terminal 23. The latch module 25 is electrically connected to the display unit 30 through the third connection terminal 23.

[0111] The adding module 24 can calculate the accumulated value, and the adding module 24 can adjust the accumulated value in response to the voltage difference between the first connection terminal 21 and the second connection terminal 22 being greater than the voltage threshold, so as to adjust the accumulated value to the sum of the original accumulated value and the preset value. The adding module 24 can generate a numerical signal according to the accumulated value, and output the numerical signal to the latch module 25. After receiving the numerical signal, the latch module 25 can latch the numerical signal and output the numerical signal through the third connection terminal 23. After receiving the numerical signal, the display unit 30 can display the accumulated value corresponding to the numerical signal according to the numerical signal. The adding module 24 can receive the numerical signal through the third connection terminal 23. In response to the adding module 24 receiving the numerical signal through the third connection terminal 23, and the voltage difference between the first connection terminal 21 and the second connection terminal 22 is less than or equal to the voltage threshold, the adding module 24 continues to output the received numerical signal to the latch module 25. In response to the addition module 24 receiving a numerical signal through the third connection terminal 23, and when the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold, the addition module 24 determines an accumulated value corresponding to the numerical signal according to the received numerical signal, updates the accumulated value to be the sum of the original accumulated value and the preset increment, generates a numerical signal according to the updated accumulated value, and continues to output the numerical signal to the latch module 25.

[0112] It can be understood that the latching function of the latch module 25 can reduce the situation where the adding module 24 makes an erroneous adjustment to the accumulated value due to interference from external signals.

[0113] It can be understood that the numerical signal is a digital signal.

[0114] In the embodiment of the present application, there is no specific limitation on the types of the latch module 25 and the adding module 24. For example, the adding module 24 may be an 8-bit adder, and the latch module 25 may be an 8-bit latch.

[0115] Exemplarily, the adding module 24 may be an 8-bit binary adder, the first connection terminal 21 may be a 1-bit signal terminal of the adder, and the second connection terminal 22 may be a 7-bit signal terminal of the adder. The latch module 25 may be an 8-bit binary latch, the initial value of the accumulated value is 00000000, and the preset increment is 1. When the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold for the first time, the adding module 24 adjusts the accumulated value from 00000000 to 00000001, and generates a numerical signal, and the generated numerical signal is a numerical signal for indicating 00000001. After receiving the numerical signal, the latch module 25 outputs the numerical signal from the third connection terminal 23. The adding module 24 can receive the numerical signal, and determine that the accumulated value is 00000001 according to the received numerical signal.

[0116] When the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold for the second time, the adding module 24 adjusts the accumulated value from 00000001 to 00000010, and generates a numerical signal, and the generated numerical signal is a numerical signal for indicating 00000010. After receiving the numerical signal, the latch module 25 outputs the numerical signal from the third connection terminal 23. The adding module 24 can receive the numerical signal and determine that the accumulated value is 00000010 according to the received numerical signal.

[0117] In some embodiments, the display unit 30 may include a decoding module 31 and a display module 32. The input end of the decoding module 31 is electrically connected to the third connection end 23, and the decoding module 31 can receive a numerical signal. The output end of the decoding module 31 is electrically connected to the input end of the display module 32.

[0118] The decoding module 31 can generate trigger information according to the received numerical signal, and output the trigger information to the display module 32. The trigger information is used to instruct the specified area on the display module 32 to light up, so that the display module 32 displays the accumulated value corresponding to the numerical signal. The display module 32 can display the accumulated value corresponding to the numerical signal according to the received trigger information.

[0119] It can be understood that the base of the accumulated value displayed by the display module 32 may be the same as or different from the base of the accumulated value calculated by the addition module 24, and the embodiments of the present application do not limit this.

[0120] In the embodiment of the present application, there is no specific limitation on the types of the display module 32 and the decoding module 31. For example, the display module 32 may be a transistor, which may include a plurality of light bars, and the decoding module 31 may be a decoder for controlling the operation of each light bar in the transistor.

[0121] Exemplarily, the display module 32 may be a transistor for displaying a 2-digit decimal value, and the decoding module 31 is a decoder that cooperates with the display module 32. After receiving the numerical signal, the decoding module 31 may determine the decimal value of the accumulated value according to the numerical signal, select the light bar in the transistor that needs to be lit according to the determined decimal value, and then the decoder outputs trigger information to the display module 32, and the trigger information is used to instruct the selected light bar in the transistor to light up.

[0122] Exemplarily, the display module 32 may be a transistor for displaying a 2-digit decimal value, and the decoding module 31 may be a decoder that cooperates with the display module 32. The adding module 24 may be an 8-bit binary adder, and the latch module 25 may be an 8-bit binary latch. In the adding module 24, the initial value of the accumulated value is 00000000, and the preset increment is 1. When the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold for the first time, the adding module 24 adjusts the accumulated value from 00000000 to 00000001, and generates a numerical signal, and the generated numerical signal is a numerical signal for indicating 00000001. After receiving the numerical signal, the latch module 25 outputs the numerical signal from the third connection terminal 23 to the decoding module 31. The decoding module 31 triggers the light bar for displaying the binary value 01 in the display module 32 to light up according to the numerical signal.

[0123] When the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold for the second time, the adding module 24 adjusts the accumulated value from 00000001 to 00000010, and generates a numerical signal, and the generated numerical signal is a numerical signal for indicating 00000010 to the decoding module 31. The decoding module 31 triggers the light bar for displaying the binary value 02 in the display module 32 according to the numerical signal.

[0124] It can be understood that the label output device 200 can be electrically connected to the output end of the decoding module 31. The label output device 200 can receive the trigger information output by the decoding module 31, determine the number of the signal line to be marked by analyzing the trigger information, and output the label corresponding to the number. The method of printing and / or outputting the label corresponding to the number of the signal line by the label output device 200 can refer to Figure 1 , Figure 2 And the related description will not be repeated here.

[0125] It can be understood that the display module 32 for displaying 2-digit decimal values ​​can intuitively display the numbers of the marked signal lines, thereby improving the convenience for the staff to view the accumulated values.

[0126] In the embodiment of the present application, the adding module 24, the latching module 25, the display module 32 and the decoding module 31 can all receive the clock signal CLK and the reset signal RST. The adding module 24, the latching module 25, the display module 32 and the decoding module 31 can be synchronized by the clock signal CLK. When the adding module 24, the latching module 25, the display module 32 and the decoding module 31 receive the reset signal RST, the adding module 24, the latching module 25, the display module 32 and the decoding module 31 are restored to the initial state, and the display module 32 displays the initial value of the accumulated value.

[0127] In some embodiments, the reminder device 100 may include a clock unit 40, which is electrically connected to the addition module 24, the latch module 25, the display module 32 and the decoding module 31 respectively. The clock unit 40 can generate a clock signal CLK and output the clock signal CLK to the addition module 24, the latch module 25, the display module 32 and the decoding module 31.

[0128] In the embodiment of the present application, there is no specific limitation on the type of the clock unit 40. For example, the clock unit 40 may be, but is not limited to, a crystal oscillator.

[0129] In other embodiments, the reminder device 100 may receive a clock signal CLK from the outside. For example, the adding module 24, the latching module 25, the display module 32, and the decoding module 31 may receive a clock signal CLK generated by a detection device from a detection device. For another example, the adding module 24, the latching module 25, the display module 32, and the decoding module 31 may receive a clock signal CLK generated by the label output device 200 from the label output device 200.

[0130] In some embodiments, the reminder device 100 may further include a reset switch S3. The reset switch S3 is electrically connected to the adding module 24, the latch module 25, the display module 32, and the decoding module 31, respectively. The reset switch S3 may receive a reset signal RST. When the reset switch S3 is closed, the reset signal RST may be transmitted to the adding module 24, the latch module 25, the display module 32, and the decoding module 31.

[0131] In the embodiment of the present application, the source of the reset signal RST is not specifically limited. For example, the reset switch S3 can be electrically connected to the detection device and receive the reset signal RST from the detection device. For another example, the reset switch S3 can be electrically connected to the label output device 200 and receive the reset signal RST from the label output device 200.

[0132] It can be understood that the reset switch S3 is a normally open switch with a reset function. In the embodiments of the present application, the type of the reset switch S3 is not specifically limited. For example, the reset switch S3 can be a key switch with a reset function. When the staff presses the reset switch S3, the reset switch S3 is closed; after the staff releases the force on the reset switch S3, the reset switch S3 automatically resets and the reset switch S3 is disconnected.

[0133] In the embodiment of the present application, the installation position of the reset switch S3 is not specifically limited. For example, the frame 300 can be a material clamp, and the reset switch S3 can be installed on a clamp body 303.

[0134] See also Figure 5 In some embodiments, the trigger unit 10 may include a relay 11 and a voltage regulating load R3. Figure 4 Compared with the trigger unit 10 shown, Figure 5 The trigger unit 10 shown will Figure 4 The switch tube Q in is replaced by relay 11. Figure 5 The trigger unit 10 in this embodiment is described in detail.

[0135] The relay 11 may include a coil KM and a contact switch S4. The contact switch S4 is a normally open switch. One end of the contact switch S4 is connected to the first switch S1, and the other end is connected to the first connection end 21, the second connection end 22 and the voltage regulating load R3. One end of the coil KM is connected to the voltage regulating load R3, and the other end is grounded. The connection relationship between the voltage regulating load R3 and the first connection end 21 and the second connection end 22 can be referred to in Figure 4 And the related description will not be repeated here.

[0136] When the first switch S1 and the second switch S2 are closed, the coil KM can receive the trigger voltage output by the second load R2 and trigger the contact switch S4 to close. The contact switch S4 can receive the first voltage and output the first voltage to the first connection terminal 21 and the voltage regulating load R3 after the contact switch S4 is closed. The voltage regulating load R3 can adjust the first voltage to the second voltage and output the second voltage to the second connection terminal 22. The voltage regulating load R3 can output the second voltage to the second connection terminal 22. In this way, a voltage difference is generated between the first connection terminal 21 and the second connection terminal 22, and the voltage difference can be equal to or nearly equal to the voltage difference between the first voltage and the second voltage, and the voltage difference is greater than the voltage threshold.

[0137] It can be understood that when the first switch S1 is disconnected, the contact switch S4 cannot receive the first voltage, and therefore cannot output the first voltage to the first connection terminal 21 and the voltage-regulating load R3. When the second switch S2 is disconnected, the coil KM is de-energized and thus cannot trigger the contact switch S4 to close, so that the contact switch S4 cannot output the first voltage to the first connection terminal 21 and the voltage-regulating load R3. That is, only when the first switch S1 and the start switch of the label output device 200 are closed at the same time, the trigger unit 10 can output the first voltage and the second voltage. In this way, the situation where the first switch S1 is accidentally touched when the label output device 200 is not working, resulting in the reminder device 100 having displayed the accumulated value, but the label output device 200 cannot output the label corresponding to the accumulated value, can be reduced.

[0138] When the marking device 1 provided in the embodiment of the present application is working and the staff needs to mark the signal line, the staff manually closes the second switch S2 to power on the label output device 200 and causes the trigger unit 10 to receive the trigger voltage. Subsequently, the staff moves the label output device 1, aligns the output port 201 with the signal line, and clicks the first switch S1. The first switch S1 is closed and outputs the first voltage to the trigger unit 10. The trigger unit 10 responds to receiving the first voltage and the trigger voltage at the same time, and outputs the first voltage and the second voltage to the first connection terminal 21 and the second connection terminal 22 respectively. When the voltage difference between the first connection terminal 21 and the second connection terminal 22 is greater than the voltage threshold, the adding unit 20 updates the accumulated value to the sum of the original accumulated value and the preset value, generates a numerical signal according to the updated accumulated value, and outputs the numerical signal to the display unit 30. The display unit 30 can display the accumulated value according to the numerical signal, and the displayed accumulated value corresponds to the number of the signal line. At the same time, the label output device 200 can obtain trigger information from the display unit 30 and determine the number of the signal line according to the trigger information. Then the label output device 200 can output the label corresponding to the signal line number, so that the label is moved out of the output port 201 and attached to the signal line.

[0139] In this way, the display of the signal line related information by the reminder device 100 can reduce the error rate when the staff marks the signal line. When the staff connects multiple signal lines to multiple connection points on the electronic product and detects the electronic product through the detection equipment connected to the signal line, the accuracy of the staff's judgment on whether the electronic product is faulty can be improved. At the same time, the trigger unit 10 triggers the display unit 30 to update the displayed content and triggers the label output device 200 to output the corresponding label only when the first voltage and the trigger voltage are received at the same time. This can reduce the situation where the first switch S1 is accidentally touched when the label output device 200 is not working, resulting in the reminder device 100 displaying the accumulated value, but the label output device 200 cannot output the label corresponding to the accumulated value.

[0140] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the above embodiments of the present application should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the attached claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.
