Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides a discharge detection device that can simulate the discharge phenomenon generated by electrical contacts on a circuit board and detect the distance between two electrical contacts when a discharge occurs.

[0024] refer to Figure 1 and Figure 2 , Figure 1 This is a first-view structural schematic diagram of the discharge detection device 100 according to an embodiment of this application. Figure 2 This is a schematic diagram of the discharge detection device 100 from a second perspective, according to an embodiment of this application.

[0025] The discharge detection device 100 includes a first electrode 10, a second electrode 20, a drive mechanism 30, a distance measurement unit 40, and a discharge detection unit (not shown in the figure).

[0026] In this configuration, the first electrode 10 and the second electrode 20 are positioned opposite each other. In practical applications, the first electrode 10 and the second electrode 20 can be discharge needles, with a conical tip and a cylindrical tail. The first electrode 10 and the second electrode 20 are used to simulate two adjacent electrical contacts on a circuit board, as well as to simulate the discharge phenomenon between the two electrical contacts.

[0027] The drive mechanism 30 is connected to the second electrode 20. The drive mechanism 30 is configured to drive the second electrode 20 to move relative to the first electrode 10. In practical applications, the first electrode 10 can be fixed, for example, fixed to the machine base of the equipment, and the drive mechanism 30 can drive the second electrode 20 to move toward the first electrode 10, or to move in the opposite direction to the first electrode 10.

[0028] In some embodiments, the drive mechanism 30 is a lead screw driven mechanism. The drive mechanism 30 includes a lead screw 31 and a motor 32. The lead screw 31 is connected to the second electrode 20 and the motor 32. The motor 32 is configured to drive the lead screw 31 to rotate, causing the lead screw 31 to move the second electrode 20 relative to the first electrode 10. It is understood that the motor 32 can be controlled by a controller to drive the lead screw 31 to rotate at a slower speed, thereby causing the second electrode 20 to move slowly.

[0029] The distance measurement unit 40 is configured to measure the distance between the second electrode 20 and the first electrode 10. The discharge detection unit is configured to detect electrical parameters when a discharge occurs between the first electrode 10 and the second electrode 20. Based on the detected electrical parameters, it can be determined whether a discharge has occurred between the first electrode 10 and the second electrode 20. In practical applications, these electrical parameters can be, for example, voltage, current, or electromagnetic waves.

[0030] Understandably, the distance measurement unit 40 can measure the distance between the second electrode 20 and the first electrode 10 in real time. When the discharge detection unit detects a discharge between the first electrode 10 and the second electrode 20, the distance measurement unit 40 can detect the distance between them at the time of the discharge, which is the discharge distance.

[0031] In some embodiments, the distance measuring unit 40 includes a first measuring element 41 and a second measuring element 42. The first measuring element 41 is connected to the first electrode 10. In practical applications, the first electrode 10 can be fixed, and the first measuring element 41 can also be fixed. For example, both the first electrode 10 and the first measuring element 41 can be fixed to the machine base of the device. In this case, they can be considered to be connected together. The second measuring element 42 is connected to the second electrode 20. During the process of the driving mechanism 30 driving the second electrode 20 to move, the second measuring element 42 also moves along with it.

[0032] The second measuring element 42 cooperates with the first measuring element 41 to measure the distance between the second electrode 20 and the first electrode 10. It can be understood that the first measuring element 41 is connected to the first electrode 10, and the second measuring element 42 is connected to the second electrode 20. Therefore, the distance measured by the cooperation of the second measuring element 42 and the first measuring element 41 is the distance between the second electrode 20 and the first electrode 10.

[0033] In some embodiments, the distance measuring unit 40 is a grating ruler. The first measuring element 41 is the scale of the grating ruler, and the second measuring element 42 is the reading head of the grating ruler. In practical applications, the scale 41 is fixed, while the reading head 42 can move with the second electrode 20 and read the scale of the scale 41 in real time, thereby measuring the distance between the second electrode 20 and the first electrode 10. The grating ruler has an accuracy of 0.0001 mm, or 0.1 μm, thus providing extremely high detection accuracy for discharge distance.

[0034] In practical applications, zero-point calibration can be performed on the grating ruler. Specifically, the first electrode 10 and the second electrode 20 are connected to the positive and negative terminals of a multimeter, respectively, and then the position of the lead screw 31 is manually and slowly adjusted. When the multimeter shows continuity (e.g., a current signal is detected), it indicates that the first electrode 10 is in contact with the second electrode 20. At this time, the reading position of the grating ruler is set as the origin (i.e., zero point), and the position of the second electrode 20 is the zero point position. Subsequently, the lead screw 31 is moved backward a certain distance, which is set as the total stroke of the lead screw 31.

[0035] In some embodiments, the distance measuring unit 40 is a photoelectric sensor, such as an infrared sensor. The first measuring element 41 is a signal receiver, such as an infrared receiver; the second measuring element is a signal transmitter, such as an infrared transmitter. The signal receiver and signal transmitter are positioned opposite each other. The signal receiver can be fixed together with the first electrode 10, while the signal transmitter moves with the second electrode 20. The distance between the signal receiver and the signal transmitter can be obtained by detecting the signal strength received by the signal receiver.

[0036] Understandably, in practical applications, the distance between the signal receiver and the signal transmitter when the first electrode 10 and the second electrode 20 are in contact can be detected using the zero-point calibration method described above, and this distance can be set as the zero-point distance. When detecting the discharge distance between the first electrode 10 and the second electrode 20, the discharge distance can be obtained by subtracting this zero-point distance from the actual distance detected by the signal receiver.

[0037] In some embodiments, the discharge detection unit is connected to the first electrode 10 and the second electrode 20. The discharge detection unit is configured to detect the voltage between the first electrode 10 and the second electrode 20 during discharge. For example, in one example, the discharge detection unit may be a voltmeter.

[0038] Understandably, when a discharge occurs between the first electrode 10 and the second electrode 20, a current path is formed between them, resulting in a voltage drop between them. When the discharge detection unit detects a voltage drop, it can be determined that a discharge has occurred between the first electrode 10 and the second electrode 20.

[0039] In some embodiments, the discharge detection unit is spaced apart from both the first electrode 10 and the second electrode 20. The discharge detection unit is configured to detect electromagnetic waves generated when a discharge occurs between the first electrode 10 and the second electrode 20.

[0040] Understandably, when a discharge occurs between the first electrode 10 and the second electrode 20, electromagnetic waves will propagate outward between them. Therefore, by detecting the electromagnetic waves during the discharge through the discharge detection unit, it can be determined that a discharge has occurred between the first electrode 10 and the second electrode 20.

[0041] In some embodiments, the discharge detection device 100 further includes a power supply. The power supply voltage can be set according to actual needs. For example, the power supply voltage can be set to the operating voltage of the circuit board being simulated for discharge. The power supply is connected to the first electrode 10 and the second electrode 20. The power supply is configured to supply power to the first electrode 10 and the second electrode 20, enabling a discharge to occur when a certain distance is reached between the first electrode 10 and the second electrode 20.

[0042] In some embodiments, the discharge detection unit is connected between the first electrode 10 and a power source or between the second electrode 20 and a power source. The discharge detection unit is configured to detect the current generated when a discharge occurs between the first electrode 10 and the second electrode 20. For example, in one example, the discharge detection unit can be a highly sensitive ammeter.

[0043] Understandably, when discharge occurs between the first electrode 10 and the second electrode 20, a current path is formed between them, thus generating a discharge current. The discharge detection unit is connected to this current path and can detect the discharge current. Therefore, if the discharge detection unit detects the discharge current, it can be determined that a discharge has occurred between the first electrode 10 and the second electrode 20.

[0044] The discharge detection device 100 of this application embodiment includes a distance measurement unit 40 and a discharge detection unit. Based on the electrical parameters detected by the discharge detection unit, it can determine whether a discharge occurs between the first electrode 10 and the second electrode 20. When a discharge occurs, the distance between the first electrode 10 and the second electrode 20 can be measured by the distance measurement unit 40, so the distance between the two electrodes when a discharge occurs can be presented intuitively.

[0045] In some embodiments, continue to refer to Figure 1 and Figure 2 The discharge detection device 100 also includes a first base 51 and a second base 52. The first electrode 10 is disposed on the first base 51, and the second electrode 20 is disposed on the second base 52.

[0046] The bottom of the second base 52 is provided with a guide rail 53. In practical applications, there can be one or more guide rails 53, for example... Figure 1 and Figure 2 As shown, there is one guide rail 53. The guide rail 53 is arranged along the line connecting the first base 51 and the second base 52. The second base 52 is connected to the drive mechanism 30, for example, to the lead screw 31. The drive mechanism 30 is configured to drive the second base 52 to move relative to the first base 51 along the guide rail 53. Therefore, during the movement of the second base 52 driven by the drive mechanism 30, the second electrode 20 can move relative to the first electrode 10.

[0047] Understandably, in practical applications, the second measuring element 42 of the distance measuring unit 40 can also be disposed on the second base 52. During the process of the drive mechanism 30 driving the second base 52 to move, the second measuring element 42 also moves along with it.

[0048] In some embodiments, the discharge detection device 100 further includes at least one guide post 60. The guide post 60 is parallel to the guide rail 53. One end of the guide post 60 is connected to, for example, fixed to, the first base 51. The other end of the guide post 60 is slidably connected to a second base 52. For example, the second base 52 may have a through hole, through which the other end of the guide post 60 passes, allowing the second base 52 to slide relative to the guide post 60. During the movement of the second base 52 driven by the drive mechanism 30, the second base 52 slides along the guide post 60.

[0049] Understandably, by setting the guide post 60 so that the second base 52 can slide along the guide post 60 when moving, the stability of the movement of the second base 52 can be improved.

[0050] This application also provides a discharge detection system. The discharge detection system includes the aforementioned discharge detection device 100 and an oscilloscope. The oscilloscope is connected to the discharge detection unit of the discharge detection device 100. The oscilloscope is configured to display the electrical parameters detected by the discharge detection unit. For example, the oscilloscope can be used to display the voltage, current, or electromagnetic waves detected by the discharge detection unit.

[0051] Therefore, when a discharge occurs between the first electrode 10 and the second electrode 20, the oscilloscope can display electrical parameters such as voltage, current or electromagnetic waves, making it easy for users to observe and improving convenience.
