Description

Technical Field

[0001] The present disclosure relates to the field of electronic equipment, and in particular to an anti-static wristband wearing monitoring system. Background Art

[0002] Electrostatic discharge is the main culprit that damages the performance of electronic components or integrated circuits. Electrostatic discharge can reach several thousand volts or tens of thousands of volts in an instant, and the damage to electronic components or integrated circuits is usually devastating and permanent. Therefore, electrostatic discharge is also called the invisible "killer" in industrial manufacturing.

[0003] Static electricity is generated due to friction, usually artificially. During the production, assembly, testing, storage, and transportation processes, static electricity may accumulate in the human body, instruments, or equipment, and even in the components themselves. When people come into contact with these charged objects without knowing it, a discharge path will be formed, instantly causing electronic components or systems to be damaged by static electricity discharge. Therefore, during the production and assembly of electronic products, operators are required to wear anti-static wristbands on their hands to discharge the static electricity of the human body to the ground by connecting to the ground. This avoids the impact of electrostatic discharge on electronic products and damage to electronic products or devices. However, people are subjective and may forget to wear the wristband or wear it improperly. Continuing production under such circumstances will inevitably cause damage to electronic products or devices, resulting in irreparable losses. Therefore, it is very necessary to monitor the wearing of anti-static wristbands for operators in production.

[0004] In the related art, the existing anti-static wristband structure cannot automatically adapt to the size of the human wrist, and there is a static electricity problem caused by improper wearing. Utility Model Content

[0039] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0040] In the related art, the existing anti-static wristband wearing monitoring system can monitor whether the operator is wearing an anti-static wristband, but it depends on the manager to observe and judge to prevent the operator from continuing the operation.

[0041] But there are the following problems:

[0042] (1) When the operator does not wear an anti-static wristband and the manager does not see the alarm information and touch screen information in time, the operator can still work normally during this period. The operator does not have any anti-static protection measures. The products produced during this period will flow to the next workstation or client until the manager discovers the abnormality.

[0043] (2) When the operator does not adjust the snap button, the bracelet does not touch the wrist for a period of time, but as the hand moves, the bracelet contacts the wrist again in a short time. Since static electricity occurs in a very short time, at the nanosecond level, there is a risk of ESD problems in this short time. This time may be shorter than the time it takes for the monitoring system to automatically obtain data. In this scenario, the monitoring system cannot detect abnormalities.

[0044] The anti-static wristband wearing monitoring system provided by the present application is introduced below in conjunction with the accompanying drawings.

[0045] like Figure 1 As shown, the present application provides an anti-static wristband 1 wearing monitoring system, the system comprising: a wristband 1, a processing device 2 and a monitoring device 3, the monitoring device 3 and the wristband 1 are respectively connected to the processing device 2 for communication;

[0046] The wristband 1 comprises a ring belt 11 for inflation and deflation, a magnetic buckle 12 is provided on the ring belt 11, and an optical sensor 13 is integrated in the magnetic buckle 12; wherein, when the wristband 1 is not worn, the magnetic buckle 12 is in a closed state, and after the wristband 1 is worn, the magnetic buckle 12 is in an open and closed state;

[0047] The processing device 2 includes an air pump 21 and a processor 22, and the air pump 21 is connected to the processor 22;

[0048] The ring belt 11 is provided with an air port 111, and the air port 111 is connected to the air pump 21 through the conduit 101, and the air pump 21 is used to inflate or deflate the ring belt 11 through the air port 111, so that the ring belt 11 fits the wrist of the user;

[0049] The monitoring device 3 includes a human-computer interaction module 31 for inputting device information of the wristband 1 and / or employee information corresponding to the wristband 1 . The human-computer interaction module 31 is connected to the processor 22 .

[0050] The present application provides an anti-static wristband 1 wearing monitoring system. In the present application, the wristband 1 includes an inflatable and deflated ring belt 11. It can be understood that the ring belt 11 in the present application is an inflatable and deflated annular conductive ring belt 11. The ring belt 11 has an inflation / deflation port 111 connected to one end of the catheter 101, and the other end of the catheter 101 is connected to the inflation pump 21. It can be understood that the processing device 2 is provided with a catheter 101 interface, and the catheter 101 is connected to the inflation pump 21 through the catheter 101 interface. The inflation pump 21 in the present application can adopt an electric inflation pump 21.

[0051] In the present application, a magnetic buckle 12 is provided on the ring belt 11, and the magnetic buckle 12 includes a magnetic buckle female seat 121 and a magnetic buckle male seat 122. When the bracelet 1 is not worn, the magnetic buckle male seat 122 is fitted with the magnetic buckle female seat 121, and is in a closed state; after the bracelet 1 is worn, the magnetic buckle male seat 122 is separated from the magnetic buckle female seat 121, and is in an open and closed state. An optical sensor 13 is integrated on the magnetic buckle female seat 121. It should be noted that the magnetic buckle male seat 122 and the magnetic buckle female seat 121 are both arranged on the inner side of the ring belt 11, that is, the side that fits with the wrist bowl, and the optical sensor 13 is connected to the processor 22 through the optical sensor 13 output signal line. In the present application, the optical sensor 13 is used to detect the luminous flux. When the magnetic buckle 12 is in a fastened state, the luminous flux in the magnetic buckle 12 is very small, less than or equal to the set initial luminous flux value B1; when the magnetic buckle 12 is in an open and closed state, the luminous flux detected by the optical sensor is the ambient luminous flux, which is greater than the initial value B1.

[0052] The present application firstly inputs the device information of the bracelet 1 and / or the employee information corresponding to the bracelet 1 through the monitoring device 3, so as to determine whether the corresponding bracelet 1 is compatible with the operator's wrist circumference. If it is not compatible, it can promptly determine which bracelet 1 is not compatible or which employee's wrist circumference is not compatible with the bracelet 1, so as to take action to prevent the conductive ring belt 11 from being unable to be tightly combined with the wrist, resulting in the inability to effectively release static electricity.

[0053] In some optional embodiments, the catheter 101 is integrated into the spring polyurethane wire.

[0054] The catheter 101 is integrated into a spring PU wire (i.e., a polyurethane wire, which is a wire made of synthetic raw materials). In the present application, the catheter 101 is integrated into the PU wire, which can delay the aging of the catheter 101.

[0055] It can be understood that in the present application, a grounding wire 14 is also provided on the wristband 1 , one end of the grounding wire 14 is connected to the wristband 1 , and the other end thereof is connected to the processing device 2 .

[0056] In some optional embodiments, the processor 22 further includes a timer (not shown in the figure);

[0057] The timer is used to record the time when the optical sensor 13 collects data.

[0058] Specifically, Figure 3 As shown, in the anti-static wristband 1 wearing monitoring system provided by the present application, after the monitoring device 3 enters the device information of the wristband 1 and / or the employee information corresponding to the wristband 1, the optical sensor 13 detects the luminous flux, and then the output signal is input to the processor 22MCU through the connecting line, and the timer T is set in the MCU. When the operator turns on the anti-static wristband 1, the optical sensor 13 outputs the luminous flux B. After the MCU determines that the luminous flux B is greater than the initial value of the luminous flux B1, the optical sensor 13 outputs the luminous flux when the anti-static wristband 1 is in a completely closed state, that is, when it is not in use, and it is recorded as the initial value of the luminous flux.

[0059] The timer is initialized to T=0 and starts timing. The MCU obtains the luminous flux signal B output by the optical sensor 13 in real time at intervals t. In order to reserve time for the operator to wear the bracelet 1, after the timer T=N*t time, if the luminous flux B is still greater than the initial luminous flux value B1, it means that the ring belt 11 and the operator's wrist circumference do not match at this time, and the inner diameter of the bracelet 1 needs to be shrunk. At this time, the MCU sends an inflation signal S1 to the electric air pump 21, and the electric air pump 21 opens the inflation valve to inflate the bracelet 1. Because when a person's hand touches the bracelet 1, the magnetic buckle mother seat 121 where the optical sensor 13 is located will be tightly combined with the person's hand, so when the MCU detects that the optical sensor 13 outputs a signal B≤B1, the MCU sends an inflation stop signal S2 to the air pump 21 again to close the inflation valve.

[0060] In order to adapt to the different sizes of operators' hands, the present application adopts an inflatable and deflated conductive ring belt 11. When inflated, the outer ring of the ring belt 11 becomes larger and the inner ring becomes smaller, which is suitable for operators with small hands. When deflated, the opposite is true, which is suitable for operators with large hands. At the same time, the conductive ring belt 11 adopts an elastic band. When the operator's hand circumference is larger than the initial inner diameter of the ring belt 11, it can automatically adapt without inflating or deflation.

[0061] In some optional embodiments, continue as Figure 2 As shown, the processing device 2 also includes:

[0062] Resistance measurement module 23, used to collect human body resistance;

[0063] One end of the resistance measuring module 23 is connected to the magnetic buckle 12, and the other end thereof is connected to the processor 22;

[0064] The processor 22 is provided with a resistance threshold, and the processor 22 is further used to compare the human body resistance with the resistance threshold, determine whether the user wears the anti-static wristband 1 according to the comparison result, and generate wearing information to be transmitted to the human-computer interaction module 31.

[0065] As a preferred implementation, an analog switch K is provided between the processor 22 and the resistance measurement module 23 , and the analog switch K is used to connect the processor 22 and the resistance measurement module 23 .

[0066] Specifically, Figure 4 As shown, in this application, when the processor 22MCU sends the inflation stop signal S2 to the inflation pump 21 again, the inflation valve is closed, and the system resistance measurement signal is sent to the analog switch K1 at the same time, the wristband 1 system resistance measurement starts, and the human body resistance is collected. The analog switch K1 is connected to the enable signal EN of the wristband system resistance measurement module 23. For example, when EN is at a high level, the analog switch K1 is closed and connected to the MCU GPIO1 port. In other words, when the ring belt 11 is matched with the wristband, the MCU sends a high level to the analog switch K1 through the GPIO1 port, and the resistance measurement module 23 starts to work and outputs the analog signal Iout.

[0067] In this application, the processor 22 is provided with a resistance threshold R1, and this application sets R1 = 3.5 × 107Ω, and the R1 value can also be modified according to the actual production situation. After the processor 22 receives the signal Iout output by the wrist strap system resistance measuring device, the actual system resistance R of the wrist strap can be calculated according to the formula R = VCC / Iout. When R < R1, the output is a high level 1, indicating that the operator is wearing an anti-static wristband 1 and the wrist adaptation is completed, and the operation can continue; otherwise, the output is a low level 0, indicating that the operator is not wearing an anti-static wristband 1 and cannot continue the operation.

[0068] In some optional embodiments, the human-computer interaction module 31 includes: a touch screen (not shown in the figure) and an alarm unit (not shown in the figure);

[0069] The touch screen is used to input and display the device information of the wristband 1 and / or the employee information corresponding to the wristband 1, and display the wearing information of the user;

[0070] The alarm unit is used to give an alarm when the user is not wearing the anti-static wristband 1.

[0071] The monitoring device 3 also includes:

[0072] The barcode scanner is used to scan the QR code of the anti-static wristband 1 to obtain device information of the anti-static wristband 1 .

[0073] It is understandable that if Figure 5 As shown, when the human-computer interaction module 31 enters the device information of the bracelet 1, the operator in this application needs to use a barcode gun to scan the product barcode, enter the product information, such as batch number, work order number, and display this information on the touch screen through the human-computer interaction module 31 before proceeding to the next step. The human-computer interaction module 31 is connected to the processor 22 via a USB interface.

[0074] After the human-computer interaction module 31 receives the scanning information of the scanner, the judgment result is automatically obtained. The anti-static wristband 1 judgment system transmits the judgment result to the processor 22 through the data signal DP / DM of the USB interface. If a high level 1 is received, the processor 22 determines that it can continue to work. After the human-computer interaction module 31 receives the information of the processor 22, it displays the barcode gun information, and the operator can continue to work; on the contrary, if a low level 0 is received, the processor 22 determines that it cannot continue to work. At this time, after the human-computer interaction module 31 receives the information, it displays the message "Please wear anti-static wristband 1", does not display the barcode gun information, and prevents the operator from continuing to work. In order to prevent the operator from leaving the post midway, returning to work without wearing the anti-static wristband 1, or the operator taking off the wristband 1 midway for other reasons, the above judgment action is repeated every time the operator performs a product information scanning action.

[0075] In some electronic industrial manufacturing, it is not necessary to scan the information of each product, but the employee information will be logged in for product production traceability, that is, the human-computer interaction module 31 enters the employee information corresponding to the wristband 1. In this case, when the employee logs in the information, Figure 6 The process determines whether the worker can continue to work. If the worker can continue to work, the employee information is displayed. Otherwise, the message "Please wear anti-static wristband 1" is displayed and the worker is prevented from continuing to work. Similarly, in order to prevent the worker from leaving the post or removing the anti-static wristband 1, the determination is repeated every time t2.

[0076] When the operator finishes the operation, the human-computer interaction interface is closed and a work stop signal S3 is sent to the MCU. After receiving the work stop signal, the MCU sends a signal S4 to the electric air pump 21. The air pump 21 opens the deflation valve to restore the anti-static wristband 1 to its initial value, making it easier for the operator to remove the wristband 1.

[0077] Through the technical solution provided by the present application, the existing workstation alarm device can be eliminated. The ring belt 11 provided by the present application can prevent static electricity problems caused by personnel not wearing the anti-static wristband 1 or wearing it improperly, reduce production losses caused by static electricity problems, and reduce labor costs and equipment costs.

[0078] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.

[0079] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0080] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
