Description

Technical Field

[0001] This invention relates to the field of object processing technology, and more specifically to a leak detection anti-false triggering device and a dicing machine. Background Technology

[0002] In many industries, certain parts require cutting processes. For example, in semiconductor processing, technologies such as wheel cutting or laser cutting are commonly used to cut semiconductor devices. Traditional wheel cutting methods are limited in production efficiency and increase cutting costs due to the hardness of the material (e.g., SiC has a Mohs hardness of 9.5, close to diamond). Furthermore, it suffers from stringent requirements for edge chipping and the potential risk of cracking after cutting, making traditional wheel cutting uneconomical. Therefore, laser cutting has become the optimal solution.

[0003] Traditional laser cutting, mainly using laser stealth cutting technology, focuses a laser beam on the inside of the workpiece to form a modified layer (the area where the explosion point connects). By precisely controlling the distance between the points, micro-cracks are formed inside, and then adjacent grains are separated by using a cleaver or vacuum cleaving.

[0004] Cutting a workpiece can cause the temperature in the cutting area to rise, especially with laser cutting. Because the laser's focused energy is high, the temperature in the cutting area rises rapidly, which can easily damage the workpiece. To address this, existing technologies spray water onto the cutting blade or substrate during cutting to lower the temperature. However, there are electronic components below the cutting module used for cutting control; therefore, it is necessary to detect any water leaks to prevent damage to these components. Summary of the Invention

[0005] The present invention was proposed in view of the above-mentioned problems. The present invention provides a leak detection anti-false triggering device and a dicing machine.

[0006] According to one aspect of the present invention, a leak detection anti-false triggering device is provided, comprising: a detection line module, a leak detection circuit module, and a processing module, wherein the detection line module includes two detection lines, one end of each of the two detection lines is connected to each other, and the other end is respectively connected to the leak detection circuit module; the processing module is used to collect the voltage of the leak detection circuit module at a preset node to determine whether the current voltage value is within the leak voltage range, and when the current voltage value is within the leak voltage range, determine that the two detection lines are in a leak state due to short circuit caused by leak; and continuously determine that the two detection lines are in the leak state as the current voltage value moves from the leak voltage range to a preset voltage within the normal voltage range, and determine that the two detection lines are in the non-leak state when the current voltage value continues to exceed the preset voltage after reaching the preset voltage from the leak voltage range; wherein the normal voltage range and the leak voltage range do not overlap.

[0007] For example, the processing module includes a first comparison submodule, wherein the first comparison submodule is used to acquire the voltage of the leakage detection circuit module at the preset node, compare the current voltage value of the acquired voltage with a preset leakage voltage value, output a corresponding leakage result signal when the current voltage value is less than the preset leakage voltage value; and continuously output the leakage result signal as the current voltage value rises from less than the preset leakage voltage value to the preset voltage, and output a corresponding non-leakage result signal when the current voltage value rises to greater than the preset voltage; wherein the leakage voltage range is: less than the preset leakage voltage value; the preset leakage voltage value is less than the preset voltage.

[0008] For example, the processing module further includes a control submodule; the control submodule is used to determine that the two detection lines are in the leakage state based on the leakage result signal.

[0009] For example, the processing module further includes: a first isolation transmission module, which is connected in series between the input terminal of the control submodule and the output terminal of the first comparison submodule to electrically isolate the control submodule and the first comparison submodule, and simultaneously transmits the leakage result signal and the non-leakage result signal output by the first submodule to the input terminal of the control submodule.

[0010] For example, the processing module further includes: a first prompting submodule, which is connected to the output terminal of the first comparison submodule and is used to issue a first prompting message when the first comparison submodule outputs the leakage result signal.

[0011] For example, the two detection lines form a closed loop with the water leakage detection circuit module; the processing module is further configured to determine whether the two detection lines are in an open circuit state where at least one detection line is open based on the voltage, and the voltage of the preset node is different in the water leakage state and the open circuit state.

[0012] For example, the processing module is further configured to determine whether the current voltage value of the collected voltage is within the open circuit voltage range, determine that the two detection lines are in the open circuit state when the current voltage value is within the open circuit voltage range, and determine that the two detection lines are in the non-open circuit state when the current voltage value is outside the open circuit voltage range; the normal voltage range, the open circuit voltage range and the leakage voltage range do not overlap.

[0013] For example, the processing module further includes a second comparison submodule; the second comparison submodule is used to acquire the voltage of the leakage detection circuit module at the preset node, and compare the current voltage value of the acquired voltage with the preset open circuit voltage value, outputting a corresponding open circuit result signal when the current voltage value is greater than the preset open circuit voltage value, and outputting a corresponding non-open circuit result signal when the current voltage value is less than the preset open circuit voltage value; wherein, the open circuit voltage range is: greater than the preset open circuit voltage value; the normal voltage range is: greater than the leakage preset voltage value and less than the preset open circuit voltage value; the preset voltage is less than the preset open circuit voltage value.

[0014] For example, the control submodule is further configured to determine that the two detection lines are in an open circuit state based on the open circuit result signal, and to determine that the two detection lines are in a normal state based on the non-leakage result signal and the non-open circuit result signal.

[0015] For example, the processing module further includes: a second isolation transmission module, which is connected in series between the input terminal of the control submodule and the output terminal of the second comparison submodule to electrically isolate the control submodule and the second comparison submodule, and simultaneously transmit the circuit breaker result signal and the non-circuit breaker result signal output by the second submodule to the control submodule.

[0016] For example, the processing module further includes: a second prompting submodule, which is connected to the output terminal of the second comparison submodule and is used to issue a second prompting message when the second comparison submodule outputs the circuit breaker result signal.

[0017] For example, the leak detection anti-false triggering device further includes a first voltage divider element, the leak detection circuit module includes a second voltage divider element, the first end of the first detection line and the first end of the second detection line are connected through the first voltage divider element; the second end of the first detection line is connected to the power supply terminal through at least the second voltage divider element; the second end of the second detection line is grounded; wherein, the preset node is the connection node between the second voltage divider element and the second end of the first detection line.

[0018] For example, the first voltage divider element includes at least one of the following: a voltage regulator and a resistor.

[0019] For example, the two detection lines are arranged parallel to each other or intertwined.

[0020] According to another aspect of the present invention, a dicing machine is provided, including the above-described anti-false triggering device for water leakage detection.

[0021] For example, the dicing machine further includes a drying module, which is used to dry the area where the two detection lines are located when it is determined that the two detection lines are in the leakage state.

[0022] For example, when the anti-false triggering device for the leakage detection is the aforementioned anti-false triggering device for the leakage detection; the control submodule is further configured to determine in real time whether the two detection lines are in the open circuit state, the leakage state, and the normal state when the drying module is drying, and control the drying module to stop working when the two detection lines reach the normal state.

[0023] According to the leakage detection anti-false triggering device and dicing machine equipment of the present invention, when the voltage value at the preset node reaches the normal voltage range from the leakage voltage range, the state corresponding to the two detection lines is not immediately switched. Instead, the two detection lines are determined to be not in a leakage state only when the voltage value exceeds the preset voltage. This can effectively prevent the two determined states from switching frequently, reduce damage to the equipment, and help ensure that the leakage can be eliminated as much as possible.

[0027] Figure 3 It shows Figure 2 The diagram shows a partial circuit diagram of the processing module. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0029] When performing leak detection, two detection lines can be set, and the voltage at a preset node in the leak detection circuit module can be used to determine whether the two detection lines are in a leaking state. Different voltage ranges at the preset node indicate different states for the two detection lines, and corresponding operations can be performed accordingly. However, this conditional judgment is relatively simple and prone to errors. For example, during cutting operations using a dicing machine, if the voltage at the preset node indicates that the two detection lines are in a leaking state and a drying operation is performed accordingly, and then the voltage is detected to have returned to the normal voltage range, if cutting operations begin immediately, the voltage fluctuations between the normal voltage range and the leaking voltage range may cause frequent activation and deactivation of the dicing machine's cutting module, adversely affecting the machine.

[0030] To at least partially solve the above problems, embodiments of the present invention provide a leak detection anti-false triggering device. For ease of understanding, the structure of the leak detection anti-false triggering device and an exemplary leak detection principle are described below.

[0031] Figure 1 A schematic block diagram of a leak detection anti-false triggering device 100 according to an embodiment of the present invention is shown. It should be noted that... Figure 1 The structure of the anti-false triggering device shown is merely an example and not a limitation of the present invention. The anti-false triggering device according to the embodiments of the present invention is not limited to... Figure 1 The structure shown. For example, Figure 1 Resistors R1 and R2, as well as the voltage regulator SW, can be omitted or replaced with other electronic components. Furthermore, Figure 1It can also include other electronic components. For example... Figure 1 As shown, the anti-false triggering device 100 may include a detection line module 110, a water leakage detection circuit module 120, and a processing module 130.

[0032] The detection line module 110 includes two detection lines, one end of each line is connected to the other, and the other end is connected to the leakage detection circuit module 120, so that the two detection lines and the leakage detection circuit module 120 form a closed loop. Figure 1 In this paper, the two detection lines are represented by their respective equivalent resistances R3 and R4. The two detection lines described herein can be made of any material and can conduct electricity through water.

[0033] Two detection lines can be positioned within a target area to detect water leakage. The target area can be determined as needed. For example, in semiconductor processing, a waterproof sheet can be placed under the cutting table, and below the sheet are numerous electronic devices and equipment used for cutting control. If the waterproof sheet breaks, some water will leak down. Therefore, one or more sets of detection lines can be positioned at the lowest point in the space below the waterproof sheet, with each set consisting of two detection lines. The relative positions of the two detection lines can be set as needed. Exemplarily, and not limitingly, the two detection lines can be arranged parallel to each other. The distance between the two parallel detection lines can be adjusted according to the detection accuracy. The closer the distance between the two detection lines, the less leakage needs to be covered, and the higher the detection accuracy; the farther the distance between the two detection lines, the more leakage needs to be covered, and the lower the detection accuracy. Alternatively, the two detection lines can be intertwined. Compared to parallel arrangement, intertwining reduces the distance between the two detection lines. Consequently, a small amount of leakage is sufficient to make the two detection lines conductive, resulting in higher detection accuracy. Therefore, the two detection lines can preferably be arranged in a way that they are intertwined.

[0034] The processing module 130 is used to collect the voltage of the water leakage detection circuit module 120 at a preset node, so as to determine whether the two detection lines are in an open circuit state where at least one detection line is open, and whether the two detection lines are in a water leakage state where they are short-circuited due to water leakage. The voltage of the preset node is different in the water leakage state and the open circuit state.

[0035] The processing module 130 can acquire the voltage at a preset node A of the leak detection circuit module 120. In one example, the processing module 130 can output the acquired voltage to a display device or other associated device, allowing the user to determine whether the two detection lines are open-circuited or leaking based on the voltage. Associated devices can be personal computers, servers, mobile terminals, etc. In another example, the processing module 130 can determine the state of the two detection lines based on the voltage at the preset node A. In one embodiment, when a leak occurs, the leak covers the two detection lines, causing a short circuit. At this time, the resistance of the two detection lines tends to be infinitesimally small, and the voltage they receive in the circuit decreases. The voltage at the preset node A is lower than the voltage under normal conditions, and the two detection lines are in a short-circuit state, which can also be called a leaking state. That is, when the voltage at the preset node is lower than the voltage under normal conditions, the two detection lines are in a leaking state due to a short circuit caused by the leak. When at least one of the two detection lines is open-circuited, both detection lines are in an open-circuit state, and the closed loop formed by the two detection lines and the leakage detection circuit module 120 is also in an open-circuit state. At this time, the voltage at the preset node A is higher than the voltage under normal conditions. For example, the voltage at the preset node A can be equal to or basically equal to the power supply voltage Vcc.

[0036] According to the above technical solution, two detection lines are set up, forming a closed loop with the leakage detection circuit module. An open circuit in the two detection lines or leakage in the area where the two detection lines are located will affect the resistance of the two detection lines, thus affecting the voltage at a preset node of the leakage detection circuit module. Therefore, the voltage at the preset node can be used to detect whether the two detection lines are leaking or open-circuited. This solution provides a simple, convenient, and timely detection of both leaks and open circuits. Of course, in practical applications, if it is only necessary to determine whether the two detection lines are leaking, without considering whether they are open-circuited, the two detection lines and the leakage detection circuit module do not need to form a closed loop; that is, the two detection lines can be left floating, and the voltage at the preset node can be used to detect whether the two detection lines are leaking.

[0037] For example, the processing module is specifically used to: determine whether the current voltage value of the collected voltage is within the leakage voltage range; if the current voltage value is within the leakage voltage range, determine that the two detection lines are in a leakage state; and determine whether the current voltage value of the collected voltage is within the open circuit voltage range; if the current voltage value is within the open circuit voltage range, determine that the two detection lines are in an open circuit state; and if the current voltage value is outside the open circuit voltage range, determine that the two detection lines are in a non-open circuit state; wherein the leakage voltage range and the open circuit voltage range do not overlap.

[0038] For two detection lines, the resistance between them differs under normal conditions, during leakage and short circuit conditions, and during open circuit conditions, resulting in different voltages at the preset node A under these conditions. Theoretically, for any specific circuit, the voltage at the preset node A should be three different fixed voltage values ​​under these three states. However, different application scenarios, such as changes in detection line length, ambient temperature, and humidity, can cause changes in the resistance of the detection lines, thus affecting the voltage value at the preset node A under different states. Exemplarily, but not limitingly, a voltage range can be set for each state to determine whether the detection line is in that state. This better adapts to various scenarios, thereby expanding the application range of the leak detection anti-false triggering device. For example, assuming the power supply voltage is 12V, 0-12V can be divided into three ranges: 0-6.4V can be set as the leak voltage range, 6.4V-9.1V as the normal voltage range, and 9.1V-12V as the open circuit voltage range. Of course, three discontinuous voltage ranges can also be set for the above three states for detection.

[0039] In one embodiment, the two-wire leakage voltage range can be set below or equal to the lower limit of the normal voltage range, and the lower limit of the circuit breaking voltage range can be set above or equal to the upper limit of the normal voltage range. This embodiment can be applied to similar... Figure 1 In the case where the potential at the preset node A is not lower than the potential at either end of the two detection lines, the voltage range setting method can be reversed. That is, the lower limit of the leakage voltage range can be set higher than or equal to the upper limit of the normal voltage range, and the upper limit of the circuit breaker voltage range can be set lower than or equal to the lower limit of the normal voltage range. For example, the voltage range setting method can be... Figure 1 When the power supply terminal (Vcc terminal) and the ground terminal are interchanged, the potential of the preset node A is not higher than the potential of either end of the two detection lines.

[0040] For example, the processing module 130 can compare the collected voltage with the leakage voltage range and the open-circuit voltage range respectively, and determine the status of the two detection lines based on the comparison results. This comparison can be achieved using a simple comparator. As mentioned above, in one embodiment, the leakage voltage range is 0–6.4V, the open-circuit voltage range is 9.1–12V, and the normal voltage range is 6.4–9.1V. The status of the two detection lines can be determined by whether the collected voltage falls within the above ranges. For example, if the collected voltage is 3V, this voltage falls within the leakage voltage range, and at this time, both detection lines are in a leakage state.

[0041] According to the above technical solution, by comparing the collected voltage with the leakage voltage range and the open circuit voltage range respectively, the status of the two detection lines can be quickly determined based on the comparison results. This solution is simple and convenient, and can quickly and accurately detect leakage and open circuit conditions.

[0042] For example, the processing module is further specifically configured to: continuously determine that the two detection lines are in a leaking state during the process of the current voltage value reaching a preset voltage within the normal voltage range from the leakage voltage range, and determine that the two detection lines are in a non-leaking state when the current voltage value continues to exceed the preset voltage after reaching the preset voltage from the leakage voltage range; wherein the leakage voltage range, the normal voltage range, and the circuit breaker voltage range do not overlap with each other.

[0043] For example, when water leakage exists in the area where the two detection lines are located (i.e., the aforementioned target area), the leakage can be removed by drying or other methods. During the drying process, the leakage between the two detection lines continuously decreases, and the voltage at the preset node slowly increases or decreases. If the upper limit of the leakage voltage range is lower than the lower limit of the circuit breaker voltage range (corresponding to the case where the potential at the preset node is not lower than the potential at either end of the two detection lines), the voltage at the preset node slowly increases as the leakage decreases. If the lower limit of the leakage voltage range is higher than the upper limit of the circuit breaker voltage range (corresponding to the case where the potential at the preset node is not higher than the potential at either end of the two detection lines), the voltage at the preset node slowly decreases as the leakage decreases. To ensure complete removal of leakage, a preset voltage can be set within the normal voltage range. This means that only when the voltage at the preset node rises above or falls below the preset voltage from the leakage voltage range can not only the leakage be completely removed, but also prevent frequent switching between the drying and cutting modules caused by fluctuations in the preset voltage near the boundary between the leakage and normal voltage ranges due to other reasons, thus improving equipment reliability. A rise above or fall below the preset voltage from the leakage voltage range can be considered as exceeding the preset voltage after it has been reached within the leakage voltage range. In one embodiment, the leakage voltage range is 0–6.4V, the circuit breaker voltage range is 9.1–12V, and the normal voltage range is 6.4–9.1V. The preset voltage within the normal voltage range is 8V. When the voltage at the preset node gradually increases from the leakage voltage range of 0–6.4V to above 6.4V, i.e., entering the normal voltage range, if the voltage at the preset node is still less than 8V, then it is determined that both detection lines are still in a leakage state. If the voltage at the preset node increases to above 8V, then it can be determined that the two detection lines are no longer in a leakage state.

[0044] According to the above technical solution, by comparing the voltage at the preset node with the leakage voltage range and the circuit breaker voltage range, the status of the two detection lines can be quickly determined based on the comparison results. Furthermore, when the voltage value at the preset node moves from the leakage voltage range to the normal voltage range, the status of the two detection lines is not immediately switched. Instead, the two detection lines are only determined to be in a non-leakage state when the voltage value exceeds the preset voltage. This effectively prevents frequent switching between the two determined states, reduces damage to the equipment, and helps ensure that leaks are eliminated as much as possible.

[0045] For example, the processing module includes a first comparison submodule, which is used to acquire the voltage of the leakage detection circuit module at a preset node, compare the current voltage value of the acquired voltage with a preset leakage voltage value, output a corresponding leakage result signal when the current voltage value is less than the preset leakage voltage value, and continuously output a leakage result signal as the current voltage value rises from less than the preset leakage voltage value to the preset voltage, and output a corresponding non-leakage result signal when the current voltage value rises to greater than the preset voltage; wherein, the leakage voltage range is: less than the preset leakage voltage value, and the preset leakage voltage value is less than the preset voltage.

[0046] The preset voltage value for leakage can be set as needed. In one example, the preset voltage value for leakage can be 6.4V. The leakage result signal is used to indicate that the two detection lines are in a leakage state, and the non-leakage result signal is used to indicate that the two detection lines are not in a leakage state.

[0047] The processing module 130 may include a comparison submodule for leak detection, such as the first comparison submodule described above. Furthermore, the processing module 130 may also include a comparison submodule for circuit breaker detection, such as the second comparison submodule described below. Figure 2 A schematic block diagram of a processing module 130 according to an embodiment of the present invention is shown. See also Figure 2 The processing module 130 includes a first comparison submodule 132 and a second comparison submodule 134. The first comparison submodule 132 and the second comparison submodule 134 can be implemented using any comparator module. By way of example and not limitation, the comparator module can be constructed using a comparator or an operational amplifier alone or in combination with other electronic components (e.g., resistors, capacitors, etc.). Figure 2 U in China A This indicates the voltage at the preset node. In the first comparison submodule 132, the current voltage value at the preset node is compared with the preset leakage voltage value.

[0048] For example, the processing module 130 may further include a control submodule 136, which may directly or indirectly receive the leakage result signal and the non-leakage result signal output by the first comparison submodule 132, so as to determine whether the two detection lines are in a leakage state based on these signals.

[0049] The first comparison submodule 132 can be implemented using a hysteresis comparator module. The characteristics of the hysteresis comparator are used to prevent frequent switching between the leakage state and the non-leakage state. Figure 3 Show Figure 2 The diagram shows a partial circuit diagram of the processing module. (See attached diagram.) Figure 3 As shown, the first comparator submodule 132 can be constructed using an operational amplifier U5B paired with three resistors R14, R15, and R22. Furthermore, Figure 3 A second comparison submodule 134 is also shown, which is used to compare the current voltage value of the acquired voltage with the preset open-circuit voltage value and output the corresponding result signal. The second comparison submodule 134 can be composed of a comparator U5A, a resistor R13, and a Zener diode Z3. Resistor R13 and Zener diode Z3 are used to provide a stable reference voltage or reference voltage for comparator U5A. Note that... Figure 3 The circuit structure shown is merely an example and not a limitation of the invention. For example, the comparison submodule used for open-circuit detection, such as the second comparison submodule 134, can also be implemented as a hysteresis comparator module similar to the first comparison submodule 132. As another example, Figure 3 The Zener diode Z3 shown can be replaced with a resistor, using a resistor voltage divider method.

[0050] Figure 3 A portion of the leak detection circuit module 120 is shown, namely Figure 3 The resistor R16 shown is... Figure 1 The resistor R1 is shown. Figure 3 The location of the preset node A is also shown. See also Figure 3 The voltage at the preset node A collected can be input to the inverting input terminal (pin 6) of the operational amplifier in the first comparison submodule 132 and the non-inverting input terminal (pin 3) of the comparator in the second comparison submodule 134.

[0051] Continue reading Figure 3A resistor R22 can be added to operational amplifier U5B as positive feedback. The voltage at the preset node is collected and input to the inverting input 6 of operational amplifier U5B in the first comparison submodule 132 and the non-inverting input 3 of comparator U5A in the second comparison submodule 134. The non-inverting input 5 of operational amplifier U5B in the first comparison submodule 132 and the negative input 2 of comparator U5A in the second comparison submodule 134 are respectively input to the first reference voltage and the second reference voltage. The second reference voltage is equal to the preset open-circuit voltage value. The first reference voltage is not necessarily equal to the preset leakage voltage value. The hysteresis comparator is a dual-limit comparator. In the first comparison submodule 132, the preset leakage voltage value (e.g., 6.4V) is used as its lower limit, and the preset voltage in the normal voltage range (e.g., 8V) is used as its upper limit. The upper and lower limits of the hysteresis comparator can be determined by resistor R22 and the first reference voltage. Therefore, the resistance value of R22 and the magnitude of the first reference voltage can be adjusted according to the required threshold voltage (including the upper and lower limits).

[0052] In the first comparison submodule 132, the voltage at the preset node is compared with a preset leakage voltage value. When the voltage at the preset node is less than the preset leakage voltage value, and during the process of the voltage at the preset node rising from less than the preset leakage voltage value to the preset voltage, the first comparison submodule 132 can output a first level, which can be either a high level or a low level. This first level corresponds to a leakage result signal, indicating that the two detection lines are in a leakage state. When the voltage at the preset node rises to greater than the preset voltage, the first comparison submodule 132 can output a second level, which can be either a low level or a high level. This second level corresponds to a non-leakage result signal, indicating that the two detection lines are in a non-leakage state. It can be understood that if the voltage drops from the normal voltage range to the leakage voltage range, and the voltage at the preset node is greater than the preset leakage voltage value but less than the preset voltage, the output is a non-leakage result signal.

[0053] In the second comparison submodule 134, the voltage at the preset node is compared with the preset open-circuit voltage value. When the voltage at the preset node is greater than the preset open-circuit voltage value, the second comparison submodule 134 outputs a third level, which is either a high level or a low level. This third level corresponds to the open-circuit result signal, indicating that the two detection lines are in an open-circuit state. Conversely, the second comparison submodule 134 outputs a fourth level, which is either a low level or a high level. This fourth level corresponds to the non-open-circuit result signal, indicating that the two detection lines are in a non-open-circuit state.

[0054] Continue reading Figure 3In the second comparator submodule 134, pin 8 of comparator U5A is connected to the power supply, and pin 4 is grounded. To reduce power supply interference, capacitor C6 is also included. One pin of capacitor C6 is connected to the power supply, and the other pin is grounded, thus filtering the power supply.

[0055] It should be noted that in the above embodiments, the upper limit of the leakage voltage range is lower than or equal to the lower limit of the normal voltage range, and the upper limit of the normal voltage range is lower than or equal to the lower limit of the circuit breaker voltage range (corresponding to the case where the potential at the preset node is not lower than the potential at either end of the two detection lines). In this case, a corresponding leakage result signal can be output when the current voltage value is less than the leakage preset voltage value; and a leakage result signal can be continuously output as the current voltage value rises from less than the leakage preset voltage value to the preset voltage. A corresponding non-leakage result signal is output when the current voltage value rises to greater than the preset voltage, and a circuit breaker result signal is output when the current voltage value at the preset node is greater than the circuit breaker preset voltage value, and a non-circuit breaker result signal is output otherwise. However, when the lower limit of the leakage voltage range is higher than or equal to the upper limit of the normal voltage range, and the lower limit of the normal voltage range is higher than or equal to the upper limit of the circuit breaker voltage range (corresponding to the case where the potential at the preset node is not higher than the potential at either end of the two detection lines), the above judgment criteria can be reversed. That is, a corresponding leakage result signal can be output when the current voltage value is greater than the preset leakage voltage value; and a leakage result signal can be continuously output as the current voltage value decreases from greater than the preset leakage voltage value to the preset voltage value; a corresponding non-leakage result signal can be output when the current voltage value decreases to less than the preset voltage value; and a circuit breaker result signal can be output when the current voltage value at the preset node is less than the preset circuit breaker voltage value, and vice versa. Accordingly, the input signals of the comparators in the first comparison submodule 132 and the second comparison submodule 134 can also be changed (i.e., the non-inverting input and the inverting input are interchanged), which will not be elaborated further.

[0056] According to the above technical solution, by setting a preset voltage in the first comparison submodule as the judgment condition for whether the leakage state has ended, the frequent switching between the leakage state and the non-leakage state can be effectively prevented, and the damage to the circuit can be reduced.

[0057] According to an embodiment of the present invention, the processing module further includes a second comparison submodule 134; the second comparison submodule 134 is used to acquire the voltage of the leakage detection circuit module at a preset node, and compare the current voltage value of the acquired voltage with the preset open circuit voltage value, outputting a corresponding open circuit result signal when the current voltage value is greater than the preset open circuit voltage value, and outputting a corresponding non-open circuit result signal when the current voltage value is less than the preset open circuit voltage value; wherein, the open circuit voltage range is: greater than the preset open circuit voltage value; the normal voltage range is: greater than the leakage preset voltage value and less than the preset open circuit voltage value; the preset voltage is less than the preset open circuit voltage value.

[0058] The preset open circuit voltage value can be set as needed; in one example, the preset open circuit voltage value could be 9.1V. The open circuit result signal indicates that the two detection lines are in an open circuit state, while the non-open circuit result signal indicates that the two detection lines are in a non-open circuit state.

[0059] See also Figure 2 The diagram illustrates the second comparison submodule 134. In the second comparison submodule 134, the current voltage value at the preset node is compared with the open-circuit preset voltage value. As described above, when the current voltage value at the preset node is greater than the open-circuit preset voltage value, the second comparison submodule 134 can output a third level, which can be either a high level or a low level. This third level corresponds to an open-circuit result signal, indicating that the two detection lines are in an open-circuit state. Conversely, when the current voltage value at the preset node is less than the open-circuit preset voltage value, the second comparison submodule 134 can output a fourth level, which can be either a low level or a high level. This fourth level corresponds to a non-open-circuit result signal, indicating that the two detection lines are not in an open-circuit state (or are in a non-open-circuit state).

[0060] For example, the processing module 130 may further include a control submodule 136, which may directly or indirectly receive the open circuit result signal and the non-open circuit result signal output by the second comparison submodule 134, so as to determine whether the two detection lines are in an open circuit state based on these signals. Further, the control submodule 136 may also determine whether the two detection lines are in a non-leaking and non-open circuit state (i.e., normal state) based on the non-leakage result signal output by the first comparison submodule 132 and the non-open circuit result signal output by the second comparison submodule 134.

[0061] The second comparison submodule 134 can compare the voltage at the preset node with the preset open circuit voltage value, thereby simply and directly determining whether the detection line is in an open circuit state.

[0062] Typically, some comparator modules do not allow, or are unlikely to allow, the input signals at the non-inverting and inverting input terminals to be equal. Therefore, the case where the current voltage value at the preset node equals the leakage preset voltage value or the circuit breaker preset voltage value can be disregarded; however, this is only an example. Alternatively, the case where the current voltage value at the preset node equals the leakage preset voltage value or the circuit breaker preset voltage value can be considered. In this case, for the case where the current voltage value equals the leakage preset voltage value, a leakage result signal or a non-leakage result signal can be output. For the case where the current voltage value equals the circuit breaker preset voltage value, a circuit breaker result signal or a non-circuit breaker result signal can be output.

[0063] The first comparison submodule and / or the second comparison submodule described above can be implemented using a software algorithm, in addition to being implemented using a hardware comparator module.

[0064] For example, the processing module further includes a control submodule; the control submodule is used to determine that the two detection lines are in a leaking state based on the leakage result signal. For example, the control submodule can also be used to determine that the two detection lines are in an open circuit state based on the open circuit result signal, and to determine that the two detection lines are in a normal state based on both the non-leakage result signal and the non-open circuit result signal.

[0065] For example, the control submodule can be implemented using processor chips such as microcontrollers, microprocessors, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits. In one embodiment, the control submodule can be directly or indirectly connected to the first comparison submodule, and / or directly or indirectly connected to the second comparison submodule. The control submodule can acquire the signals output by the first comparison submodule and / or the second comparison submodule, and determine the state of the two detection lines based on the signals. For example, if the first comparison submodule outputs a high level and the second comparison submodule outputs a low level, the control submodule can determine that the two detection lines are in a leaking state based on the levels output by the two comparison submodules.

[0066] According to the above technical solution, by setting up a control submodule, the status of the two detection lines can be quickly determined based on the signal type obtained by the control submodule.

[0067] For example, the processing module further includes: a first isolation transmission module, configured to be connected in series between the input terminal of the control submodule and the output terminal of the first comparison submodule to electrically isolate the control submodule from the first comparison submodule, while transmitting the leakage result signal and the non-leakage result signal to the input terminal of the control submodule; and / or a second isolation transmission module, configured to be connected in series between the input terminal of the control submodule and the output terminal of the second comparison submodule to electrically isolate the control submodule from the second comparison submodule, while transmitting the circuit breaker result signal and the non-circuit breaker result signal to the input terminal of the control submodule.

[0068] In one embodiment, the first isolated transmission module and / or the second isolated transmission module can be implemented using an optical coupler. (Continue reading...) Figure 3In the first comparison submodule 132, the output pin 7 of operational amplifier U5B is connected to pin 1 of the first isolation transmission module U15 via resistor R18. Pins 3 and 4 of the first isolation transmission module U15 are connected to multiple pins of the control submodule. In the second comparison submodule 134, the output pin 1 of comparator U5A is connected to pin 1 of the second isolation transmission module U16 via resistor R17. Pins 3 and 4 of the first isolation transmission module U15 are connected to multiple pins of the control submodule to transmit leakage and non-leakage result signals to the control submodule. Similarly, pins 3 and 4 of the second isolation transmission module U16 are connected to multiple pins of the control submodule to transmit circuit breaker and non-circuit breaker result signals to the control submodule. Figure 3 As shown, the first isolation transmission module U15 and the second isolation transmission module U16 also have pin 2, which is directly grounded.

[0069] According to the above technical solution, by setting a first isolation transmission module and / or a second isolation transmission module, the front-end circuit and the back-end circuit can be effectively isolated while realizing signal transmission, preventing them from affecting each other, thereby ensuring the accuracy of the detection results.

[0070] For example, the processing module further includes: a first prompting submodule and / or a second prompting submodule, wherein the first prompting submodule is connected to the output terminal of the first comparison submodule and is used to issue a first prompting message when the first comparison submodule outputs a water leakage result signal; and the second prompting submodule is connected to the output terminal of the second comparison submodule and is used to issue a second prompting message when the second comparison submodule outputs a circuit breaker result signal.

[0071] Either the first prompt submodule or the second prompt submodule can be implemented using any module capable of outputting prompt information, including but not limited to one or more of the following: a display screen, a speaker, a communication device, an alarm light, and a buzzer. Either the first prompt information or the second prompt information can be implemented using any suitable information format, such as one or more of the following: image information, video information, audio information, light information, and digital information. In one embodiment, such as... Figure 3 As shown, the first prompt submodule can be implemented using LED D6, and the second prompt submodule can be implemented using LED D5. For example, see [link to example]. Figure 3 LED D6 can be connected in series between the output pin 7 of operational amplifier U5B in the first comparator submodule 132 and pin 1 of the first isolation transmission module U15. LED D5 can be connected in series between the output pin 1 of comparator U5A in the second comparator submodule 134 and pin 1 of the second isolation transmission module U16.

[0072] According to the above technical solution, by setting a first prompt submodule and / or a second prompt submodule, corresponding prompt information can be output in a timely manner when the two detection lines are in an open circuit or leaking state, prompting the user to carry out maintenance as soon as possible. This technical solution can effectively and promptly notify the user of the status of the two detection lines, resulting in a better user experience.

[0073] For example, the leak detection anti-false triggering device further includes a first voltage divider element, the leak detection circuit module includes a second voltage divider element, the first end of the first detection line and the first end of the second detection line are connected through the first voltage divider element; the second end of the first detection line is connected to the power supply terminal through at least the second voltage divider element; the second end of the second detection line is grounded; wherein, the preset node is the connection node between the second voltage divider element and the second end of the first detection line.

[0074] For example, the voltage at the preset node can be positioned in different ranges under different conditions by setting a first voltage divider element and a second voltage divider element. In one embodiment, the first voltage divider element can be implemented as a voltage regulator and / or a resistor. When the power supply terminal Vcc is directly connected to the second end of the first detection line, if there is a leak between the first and second detection lines, the theoretical voltage at the preset node A is 0. When at least one of the two detection lines is open-circuited, the theoretical voltage at the preset node A is equal to the power supply voltage Vcc. Under normal conditions, the theoretical voltage at the preset node A is the regulated voltage of the voltage regulator or the voltage obtained by voltage division by the resistor (referring to the resistor in the first voltage divider element). If there is no first voltage divider element and the two detection lines are directly connected together, then under open-circuit conditions, the voltage at the preset node A is Vcc; under short-circuit conditions and under normal conditions, if the resistance of the detection lines is not considered, the voltage at the preset node A is 0, but if the resistance of the detection lines is considered, there should actually be a certain voltage value, and they should be slightly different. The function of the first voltage divider element is to widen the voltage difference between short-circuit and normal conditions.

[0075] For example, the second voltage divider element can be a resistor. Figure 1 As shown, the second voltage divider can be a series connection of resistor R1 (which can be called the first resistor) and resistor R2 (which can be called the second resistor). The first terminal of resistor R1 is connected to the power supply terminal Vcc, and the second terminal is connected to the first terminal of resistor R2. The second terminal of resistor R2 is connected to the second terminal of the first detection line. By setting the second voltage divider, the leakage voltage range, normal voltage range, and open-circuit voltage range can be made to not overlap. In this way, the processing module can determine the status of the two detection lines based on the voltage range of the preset node.

[0076] According to the above technical solution, by setting the first voltage divider element and the second voltage divider element, the voltage ranges corresponding to different states can be made to not overlap with each other, thereby enabling the state between the two detection lines to be quickly determined based on the voltage of the preset node.

[0077] According to another aspect of this application, a dicing machine is also provided, which includes the anti-false triggering device 100 for water leakage detection as described in any of the above embodiments.

[0078] For example, the dicing machine also includes a drying module. The drying module is used to dry the area where the two detection lines are located when it is determined that the two detection lines are leaking.

[0079] The drying module can be communicatively connected to the processing module 130, such as the control submodule within the processing module 130. This communicative connection can be achieved, for example, via any wired or wireless communication method. The processing module 130 can generate corresponding control signals based on the currently determined states of the two detection lines to control the operation of the drying module. In one example, when the processing module 130 receives a leakage result signal, it can generate a first control signal to control the drying module to perform a drying operation. The first control signal can be, for example, a high level. When the processing module 130 receives a non-leakage result signal, it can generate a second control signal to control the drying module to stop performing the drying operation. The second control signal can be, for example, a low level.

[0080] The drying module can dry the two detection lines in time when they are leaking, thereby reducing the damage to electronic components or equipment caused by the leak.

[0081] For example, when the leak detection anti-false triggering device is the leak detection anti-false triggering device including the control submodule, the control submodule is also used to determine in real time whether the two detection lines are in an open circuit state, a leak state, or a normal state when the drying module is drying, and to control the drying module to stop working when the two detection lines reach the normal state.

[0082] For example, in the embodiment described above that determines whether there is a leak based solely on the leak voltage range, upon determining a leak, the drying module can be controlled to dry the device, causing the voltage at the preset node to gradually rise until it exceeds the preset leak voltage value. Once the voltage at the preset node exceeds the preset leak voltage value, the control submodule receives a non-leakage result signal, confirming a non-leakage state. If it is also not in an open-circuit state, it can be determined to be in a normal state, at which point drying can be stopped, and the cutting operation can continue normally. This approach directly sets the control submodule to determine no leak after the voltage exceeds the preset leak voltage value, and then controls the cutting module of the dicing machine to start working. In practical applications, when the voltage at the preset node fluctuates slightly around the preset leak voltage value (e.g., 6.4V), it will frequently trigger the opening and closing of the cutting module, adversely affecting the dicing machine. Therefore, a more preferable approach is to combine the leak voltage range with a preset voltage within the normal voltage range to determine whether there is a leak. In the embodiment described above, which combines the leakage voltage range with a preset voltage within the normal voltage range to determine whether a leakage is occurring, upon determining a leakage, the drying module can be controlled to dry the device, causing the voltage at the preset node to gradually rise until it exceeds the preset leakage voltage value. Drying continues until the voltage at the preset node rises above the preset voltage within the normal voltage range. At this point, the control submodule receives a non-leakage result signal, confirming a non-leakage state. If it is also in a non-open-circuit state, it can be determined to be in a normal state. At this point, drying can be stopped, and the cutting operation can continue normally.

[0083] Since the resistance in the circuitry (which can be referred to as the downstream circuitry) of the drying module is typically large, for example, greater than 5MΩ, the resistance value can change in a humid environment. Therefore, optionally, the circuit board containing the drying module can be coated with a three-proof material, namely a waterproof, moisture-proof, and anti-static material. For example, at least some of the electronic components in the leak detection anti-false triggering device can also be arranged on the aforementioned circuit board.

[0084] Those skilled in the art can understand the specific implementation scheme of the above-mentioned dicing machine equipment by reading the relevant description of the anti-false triggering device 100 for water leakage detection. For the sake of brevity, it will not be described in detail here.

[0085] As can be seen from the above, this application provides a leak detection anti-false triggering device, including: a detection line module, a leak detection circuit module, and a processing module. The detection line module includes two detection lines, one end of each detection line being connected to the other, and the other end being connected to the leak detection circuit module. The processing module is used to collect the voltage of the leak detection circuit module at a preset node to determine whether the current voltage value is within the leak voltage range. When the current voltage value is within the leak voltage range, it determines that the two detection lines are in a leaking state due to a short circuit caused by leakage. Furthermore, it continuously determines that the two detection lines are in a leaking state as the current voltage value moves from the leak voltage range to a preset voltage within the normal voltage range. When the current voltage value continues to exceed the preset voltage after reaching the preset voltage from the leak voltage range, it determines that the two detection lines are not in a leaking state. The normal voltage range and the leak voltage range do not overlap.

[0086] According to the leakage detection anti-false triggering device of the present invention, when the voltage value at the preset node reaches the normal voltage range from the leakage voltage range, the state corresponding to the two detection lines is not immediately switched. Instead, the two detection lines are determined not to be in a leakage state only when the voltage value exceeds the preset voltage. This can effectively prevent the two determined states from switching frequently, reduce damage to the equipment, and help ensure that the leakage can be eliminated as much as possible.

[0087] For example, the processing module includes a first comparison submodule, which is used to acquire the voltage of the leakage detection circuit module at a preset node, compare the current voltage value of the acquired voltage with a preset leakage voltage value, output a corresponding leakage result signal when the current voltage value is less than the preset leakage voltage value, and continuously output a leakage result signal as the current voltage value rises from less than the preset leakage voltage value to the preset voltage value, and output a corresponding non-leakage result signal when the current voltage value rises to greater than the preset voltage value; wherein the leakage voltage range is: less than the preset leakage voltage value; the preset leakage voltage value is less than the preset voltage. The leakage result signal indicates that the two detection lines are in a leakage state, and the non-leakage result signal indicates that the two detection lines are not in a leakage state.

[0088] For example, the processing module further includes a control submodule; the control submodule is used to determine whether the two detection lines are in a leaking state based on the leakage result signal.

[0089] For example, the processing module further includes: a first isolation transmission module, which is connected in series between the input terminal of the control submodule and the output terminal of the first comparison submodule to electrically isolate the control submodule and the first comparison submodule, and simultaneously transmit the leakage result signal and the non-leakage result signal output by the first submodule to the input terminal of the control submodule.

[0090] For example, the processing module further includes: a first prompt submodule, which is connected to the output terminal of the first comparison submodule and is used to issue a first prompt message when the first comparison submodule outputs a leakage result signal.

[0091] For example, the two detection lines form a closed loop with the water leakage detection circuit module; the processing module is also used to determine whether the two detection lines are in an open circuit state where at least one detection line is open based on the voltage, and the voltage of the preset node is different in the water leakage state and the open circuit state.

[0092] For example, the processing module is further configured to determine whether the current voltage value of the collected voltage is within the open circuit voltage range, determine that the two detection lines are in an open circuit state when the current voltage value is within the open circuit voltage range, and determine that the two detection lines are in a non-open circuit state when the current voltage value is outside the open circuit voltage range; the normal voltage range, the open circuit voltage range and the leakage voltage range do not overlap.

[0093] For example, the processing module further includes a second comparison submodule; the second comparison submodule is used to acquire the voltage of the leakage detection circuit module at a preset node, and compare the current voltage value of the acquired voltage with the preset open circuit voltage value. When the current voltage value is greater than the preset open circuit voltage value, the corresponding open circuit result signal is output; when the current voltage value is less than the preset open circuit voltage value, the corresponding non-open circuit result signal is output. The open circuit voltage range is: greater than the preset open circuit voltage value; the normal voltage range is: greater than the preset leakage voltage value and less than the preset open circuit voltage value; the preset voltage is less than the preset open circuit voltage value. The open circuit result signal indicates that the two detection lines are in an open circuit state, and the non-open circuit result signal indicates that the two detection lines are not in an open circuit state.

[0094] For example, the control submodule is also configured to determine that the two detection lines are in an open circuit state based on the open circuit result signal, and to determine that the two detection lines are in a normal state based on the non-leakage result signal and the non-open circuit result signal together.

[0095] For example, the processing module further includes a second isolation transmission module, which is connected in series between the input terminal of the control submodule and the output terminal of the second comparison submodule to electrically isolate the control submodule and the second comparison submodule, and simultaneously transmit the circuit breaker result signal and the non-circuit breaker result signal output by the second submodule to the control submodule.

[0096] For example, the processing module further includes: a second prompting submodule, which is connected to the output terminal of the second comparison submodule and is used to issue a second prompting message when the second comparison submodule outputs a circuit breaker result signal.

[0097] For example, the leak detection anti-false triggering device further includes a first voltage divider element, the leak detection circuit module includes a second voltage divider element, the first end of the first detection line and the first end of the second detection line are connected through the first voltage divider element; the second end of the first detection line is connected to the power supply terminal through at least the second voltage divider element; the second end of the second detection line is grounded; wherein, the preset node is the connection node between the second voltage divider element and the second end of the first detection line.

[0098] For example, the first voltage divider element includes at least one of the following: a voltage regulator and a resistor.

[0099] For example, the two detection lines are arranged parallel to each other or intertwined.

[0100] According to another aspect of the present invention, a dicing machine is provided, including the above-mentioned anti-false triggering device for water leakage detection.

[0101] For example, the dicing machine also includes a drying module for drying the area where the two detection lines are located when it is determined that the two detection lines are in a leaking state.

[0102] For example, when the leak detection anti-false triggering device is the leak detection anti-false triggering device including the control submodule, the control submodule is also used to determine in real time whether the two detection lines are in an open circuit state, a leak state, or a normal state when the drying module is drying, and to control the drying module to stop working when the two detection lines reach the normal state.
