DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0021] See also Figure 1, the embodiment of the present application provides a liquid leakage detection device 1000, and also provides a control method applied to the liquid leakage detection device 1000. In this embodiment, the liquid leakage detection device 1000 is used to detect the leakage or sealing condition of the product 2000 to be detected, and the product 2000 to be detected may include a washing machine, an air conditioner, a refrigerator, a freezer, a dishwasher, etc. For example, the product 2000 to be detected includes a washing machine, and it is necessary to detect whether the washing machine is leaking to ensure that the washing machine can operate normally when entering the working state, to avoid the presence of leaking locations on the cylinder body or pipes (such as water inlet pipes, water outlet pipes) and other components of the washing machine, to avoid the leaked liquid from flowing out of the washing machine and polluting the environment, and to avoid the leaked liquid from wetting the circuit structure of the washing machine and causing a local circuit short circuit.

[0022] In the present embodiment, the liquid leakage detection device 1000 is used to be arranged on the ground. The liquid leakage detection device 1000 includes a detection platform 700, a detection device 100 and a control device 900, and the detection platform 700 is roughly a horizontal platform, and the detection platform 700 is used to carry the product to be detected 2000 and the detection device 100. In the case where the product to be detected 2000 is arranged on the detection platform 700, the detection device 100 is located below the gravity direction of the product to be detected 2000, so that the liquid can drip on the detection device 100, and in the case where the liquid drips on the detection device 100, the detection device 100 can transmit a signal to the outside. In the present embodiment, the detection device 100 is electrically connected to the control device 900 to realize data transmission and information transmission, and the control device 900 can judge whether there is liquid dripping on the detection device 100 according to the signal transmitted by the detection device 100, so as to judge whether the product to be detected 2000 has a leakage problem. In this embodiment, the leakage detection equipment 1000 detects the leakage of the product to be detected 2000 through the detection device 100, and can accurately and quickly determine whether the product to be detected 2000 has a leakage problem without manual inspection, which greatly improves the efficiency of determining whether the product to be detected 2000 is leaking.

[0023] In this embodiment, the control device 900 can also calculate the location of the leakage problem on the product to be detected 2000 according to the signal transmitted by the detection device 100, and can transmit the relevant information to the staff or other maintenance equipment. Specifically, the leakage detection device 1000 in this embodiment also includes an interactive device 300, and the interactive device 300 is electrically connected to the control device 900. The control device 900 can provide the specific situation of the product to be detected 2000 with a leakage problem to the staff or other maintenance equipment through the interactive device 300. As an example, the interactive device 300 may include a display screen, and the control device 900 can display data or simulated images including the leakage location on the display screen, so that the staff can quickly determine and find the leakage location. As another example, the interactive device 300 may include at least one of a voice broadcast device, a warning lamp, a buzzer, and the like.

[0024] See also Figure 2 In this embodiment, the detection device 100 includes a detection board 10 and a plurality of sensors 20. The detection board 10 is a roughly flat structure. In actual application, the detection board 10 is arranged on the detection table 700. The detection board 10 is located below the gravity direction of the product 2000 to be detected. The liquid leaking from the product 2000 to be detected can drip onto the detection board 10. The sensor 20 is arranged on the detection board 10. When the sensor 20 is in contact with the liquid, the sensor 20 can detect the presence of the liquid and transmit a signal to the outside to indicate that there is liquid on the detection board 10, and further indicates that there is a leakage problem in the product 2000 to be detected. In this embodiment, the detection board 10 has a plurality of detection areas 111, and the plurality of sensors 20 are distributed in the plurality of detection areas 111. At least one sensor 20 is arranged on each detection area 111, so that each detection area 111 has the ability to detect liquid. In actual application scenarios, if there is liquid on a certain detection area 111, the staff can quickly determine the area with leakage problem on the product 2000 to be detected based on the position of the detection area 111 on the detection board 10, and specifically check the leakage area to quickly find the component or part of the product 2000 to be detected that has leakage, which greatly improves the efficiency of checking the leakage of the product 2000 to be detected. In this embodiment, the detection board 10 can be a printed circuit board, and the printing technology is used to generate a two-dimensional plane detection range to cover all points in the detection area 111.

[0025] In this embodiment, the detection area 111 is roughly rectangular, and multiple detection areas 111 are arranged in an array on the detection plate 10 to facilitate area division and reduce the initial design cost. In other embodiments, the shape, number and arrangement of the detection area 111 can be set according to the type and specific structure of the product 2000 to be detected. As an example, in the scenario where the detection device 100 is used to detect an evaporating coil, the detection area 111 can be annular, and multiple annular detection areas 111 have a common center, and the center defines a radial direction. Multiple detection areas 111 are arranged around the center in sequence along the radial direction, and the detection area 111 located in the outer circle surrounds the outer periphery of the detection area 111 located in the inner circle. The multiple detection areas 111 can better correspond to the multi-circle tube body of the evaporating coil, and can more accurately determine the tube body with leakage problems.

[0026] In this embodiment, multiple sensors 20 are arranged in an array, and multiple sensors 20 are distributed in multiple detection areas 111. The number of sensors 20 in each detection area 111 is roughly the same, so that the sensitivity of multiple detection areas 111 is similar; multiple sensors 20 in each detection area 111 are distributed more evenly, so that the sensitivity of each part of the detection area 111 is similar, so as to effectively detect whether there is liquid dripping in a certain detection area 111. In this embodiment, the sensor 20 may include circuit components, such as resistors and / or capacitors, etc. After the circuit components come into contact with the liquid, their physical parameters change, such as the resistance becomes larger or smaller, and the current of the circuit components in the circuit also changes accordingly. In some other embodiments, the sensor 20 may also include an optical sensor 20, a humidity sensor 20, etc., which can determine whether liquid drips on the detection board 10 according to the change in light intensity or humidity.

[0027] See also Figure 2 and Figure 3In this embodiment, the detection device 100 further includes a signal processing module 30, which is connected to the detection board 10. The signal processing module 30 is electrically connected to the multiple sensors 20 respectively, and the multiple sensors 20 and the signal processing module 30 are both located in the detection circuit. The signal processing module 30 is electrically connected to the control device 900 to realize data transmission. In this embodiment, the signal processing module 30 is used to obtain signals from multiple sensors 20, such as current signals, voltage signals, etc., and perform signal processing on the signals of the sensors 20 to generate detection signals. The signal processing may include any one of amplification, filtering, digital-to-analog conversion, etc. The signal processing module 30 can transmit the detection signal to the control device 900. In this embodiment, the signal transmitted by the sensor 20 that contacts the liquid is different from the signal transmitted by the sensor 20 that does not contact the liquid, and then the detection signals generated by the signal processing of the two signals by the signal processing module 30 are also different, and the control device 900 can determine whether the sensor 20 contacts the liquid according to the detection signal.

[0028] As an example, the detection signal is an amplified and filtered current signal. The control device 900 compares the current signal with a preset current threshold. When the current signal exceeds the current threshold, the control device 900 can determine that the sensor 20 is in contact with liquid and determine that the product 2000 to be detected has a leakage problem.

[0029] As another example, the detection signal is a pulse signal after the current signal or voltage signal is converted and processed. The control device 900 compares the pulse signal with the preset pulse signal. When the pulse amplitude of the detection signal is greater than the amplitude of the preset pulse signal, the control device 900 can determine that the sensor 20 is in contact with the liquid, and determine that the product to be detected 2000 has a leakage problem. In an actual application scenario, the signal processing module 30 sequentially receives the signals of multiple sensors 20, processes the signals, and transmits them to the control device 900, so as to sequentially scan the multiple sensors 20 on the detection board 10 (for example, the branch where each sensor 20 is located can be turned on in turn, and the current or voltage signal of the branch can be obtained to achieve scanning), so as to accurately and comprehensively obtain the water-encountering conditions of multiple detection areas 111, and then accurately determine whether the product to be detected 2000 has a leakage problem.

[0030] In actual application scenarios, the control device 900 can determine the detection area 111 where the sensor 20 is located based on the sensor 20 in contact with the liquid, and then obtain the information of the detection area 111 where the liquid is located, and determine the area where the leakage problem occurs on the product to be detected 2000 based on the information of the detection area 111 where the liquid is located. In this embodiment, the information of the detection area 111 where the liquid is located may include the position of the detection area 111 on the detection board 10, for example, the row and column of the array where the detection area 111 is located; or multiple detection areas 111 are marked, and the information of the detection area 111 may include the number of the detection area 111.

[0031] As can be seen from the above, the detection device 100 provided in this embodiment includes a detection board 10, a plurality of sensors 20 and a signal processing module 30. The detection board 10 is provided with a plurality of detection areas 111, and a plurality of sensors 20 are respectively arranged in the plurality of detection areas 111. Each detection area 111 is provided with at least one sensor 20, so that each detection area 111 has the function of detecting liquid. The signal processing module 30 is arranged on the detection board 10, and the plurality of sensors 20 and the signal processing module 30 are electrically connected. The plurality of sensors 20 and the signal processing module 30 are located on the same detection circuit, and the signal processing module 30 can sequentially obtain the signals of the plurality of sensors 20. The signal processing module 30 is electrically connected to the control device 900. After the signal processing module 30 performs signal processing on the signal of the sensor 20, the detection signal is generated and transmitted to the control device 900. The control device 900 determines whether the sensor 20 is in contact with the liquid according to the detection signal.

[0032] Under the setting of this embodiment, the multiple sensors 20 greatly enhance the ability of the detection device 100 to detect liquids. The multiple sensors 20 are distributed on multiple detection areas 111, so that the detection range of the detection device 100 is wide, and the sensitivity of the detection device 100 is improved. The detection device 100 in this embodiment is conducive to subsequent applications. Specifically, each sensor 20 corresponds to the detection area 111 where it is located. The control device 900 can determine whether the sensor 20 contacts the liquid according to the detection signal of the sensor 20, and determine the detection area 111 where it is located according to the sensor 20, so as to quickly determine the detection area 111 where the liquid exists on the detection board 10, so that the background calculation is simple, the result is output quickly, and the accuracy is high. The control device 900 can also correspond to the area on the product 2000 to be detected according to the detection area 111 where the liquid is located, and can quickly determine the component or part of the product 2000 to be detected that leaks liquid, thereby improving the efficiency of detecting the leakage of the product 2000 to be detected.

In this embodiment, the detection device 100 includes at least a detection board 10 and a plurality of sensors 20, a plurality of detection areas 111 are provided on the detection board 10, and the plurality of sensors 20 are respectively arranged in the plurality of detection areas 111, and at least one sensor 20 is arranged in each detection area 111, so that each detection area 111 has the function of detecting liquid, thereby improving the detection capability of the detection device 100. In this embodiment, the detection device 100 is wirelessly connected to the control device 900 to achieve information transmission between the detection device 100 and the control device 900. Specifically, the control device 900 can receive the detection signal of the sensor 20 and determine the distribution of the liquid on the detection plate 10 according to the detection signal of the sensor 20. Under the setting of this embodiment, the liquid leakage detection device 1000 can automatically detect the position or component of the product 2000 to be detected where the water leakage problem occurs, with high speed, high accuracy and small error.

In an actual application scenario, multiple sub-areas 1111 of multiple detection areas 111 are arranged in an array, and the control device 900 can determine the information of the sub-area 1111 where the sensor 20 is located based on the detection signal of a certain sensor 20.

[0043] In summary, the present application provides a liquid leakage detection device 1000, which includes a control device 900, a detection platform 700 and a detection device 100. The detection platform 700 is used to carry a product 2000 to be detected. The detection device 1000 is arranged on the detection platform 700. When the product 2000 to be detected and the detection device 100 are arranged on the detection platform 700, the detection device 100 is located below the product 2000 to be detected in the direction of gravity, so that the liquid leaked from the product 2000 to be detected can drip onto the detection plate 10 of the detection device 1000.

Specifically, the control device 900 can receive the detection signal of the sensor 20 and determine the distribution of the liquid on the detection plate 10 according to the detection signal of the sensor 20. Under the setting of this embodiment, the liquid leakage detection device 1000 can automatically detect the position or component of the product 2000 to be detected where the water leakage problem occurs, with high speed, high accuracy and small error.

[0044] Based on the liquid leakage detection device described above, the present application also provides a control method for the liquid leakage detection device. The control method for the liquid leakage detection device can be applied to the liquid leakage detection device provided in any of the above embodiments. In the control method, the liquid leakage detection device can determine the location of the liquid leakage problem on the product to be detected according to the position of the liquid on the detection plate, which can improve the efficiency and accuracy of detecting the leakage of the product to be detected. Please refer to Figure 4 The control method of the liquid leakage detection device provided in the embodiment of the present application includes the following steps S110 to S120.

[0045] Step S110, acquiring detection information of the detection device, where the detection information represents position information of an area where liquid exists on the detection plate.

[0046] In the present embodiment, the control device obtains the detection information from the detection device by means of wireless communication. In some embodiments, the detection information can represent the specific information of the position of the liquid on the detection plate, such as representing that the liquid is located in a certain area of ​​the detection plate, such as representing that the liquid is located in a certain position on the detection plate. In the present embodiment, the detection information is data related to the position of the liquid, and the position of the liquid on the detection plate is obtained after calculation by the control device. Under the setting of the present embodiment, the detection device needs to calculate fewer steps, which makes the composition of the detection device simple and the cost of the detection device low.

[0047] In some embodiments, obtaining the detection information of the detection device includes three steps. The first step may include: obtaining the detection signals of multiple sensors. The detection signal transmitted by the sensor in contact with the liquid is different from the detection signal transmitted by the dry sensor, and the control device can distinguish whether the sensor is in contact with the liquid based on the detection signal of the sensor. Therefore, the second step may include: determining the target sensor that detects the liquid among the multiple sensors based on the detection signal. After determining the target sensor, perform the third step: determine the position information of the target sensor as the detection information. In this embodiment, a two-dimensional coordinate system can be established on the detection board, and the detection information of the target sensor can include the coordinates of the target sensor on the two-dimensional coordinate system.

[0048] S120, determining a leakage position according to the detection information, where the leakage position represents a position where the leakage occurs on the product to be detected.

[0049] In this embodiment, the detection information includes detection signals from multiple sensors, and the control device calculates the position where the leakage occurs on the product to be detected based on the detection signals from the multiple sensors.

[0050] In some embodiments, determining the leakage location according to the detection information includes two steps. The first step may include: determining the target detection area corresponding to the position information of the target sensor. In this embodiment, the detection board is divided into multiple detection areas, and multiple detection areas are arranged in an array, and at least one sensor is arranged in each detection area. Multiple detection areas are distributed in the two-dimensional coordinate system mentioned above, and each detection area has its own range in the two-dimensional coordinate system. The detection area where the target sensor is located can be determined according to the coordinates of the target sensor, and the area is defined as the target detection area for subsequent calculations.

[0051] In some other embodiments, the number of the target sensor in the multiple sensors can be used as the detection information. Specifically, the multiple sensors are numbered, and the numbering method can be selected in ascending order, according to the format of 1, 2, 3, 4... or A, B, C, D..., then the expression of the detection information can be: sensor No. 1, sensor No. 2, sensor No. 3, sensor C, sensor D, etc. In this embodiment, each detection area has its own area information, and the area information can be the position of the detection area in the array, such as the row and column. The area information of the detection area can also be the number of the detection area, for example, it can be in ascending order, according to the format of 1, 2, 3, 4... or A, B, C, D..., then the expression of the area information of the detection device can be: detection area No. 1, detection area No. 2, detection area No. 3, detection area C, detection area D, etc. In some embodiments, the number can also represent the position of the detection area where the liquid is located in the array, for example, the first number or letter represents the number of rows of the detection area in the array, and the second number or letter represents the number of columns of the detection area in the array. As an example, the detection area where the liquid is located is labeled A3, which indicates that the detection area is located in the first row and third column of the array. In this embodiment, the area information of a detection area corresponds to the label of at least one sensor located in the detection area, and the control device can determine that the detection area where the target sensor is located is the target detection area according to the label of the target sensor.

[0052] After determining the target detection area, the second step is performed: according to the preset leakage correspondence table, the potential leakage area corresponding to the target detection area is determined. In this embodiment, multiple potential leakage areas are divided on the product to be detected. There are many ways to divide the potential leakage area. As an example, the side of the product to be detected facing the detection board can be artificially divided into multiple potential leakage areas, and multiple components used for temporary storage or storage of liquid in the product to be detected correspond to multiple potential leakage areas. In actual application scenarios, a component of the product to be detected may correspond to multiple potential leakage areas due to its configuration, for example, a longer tube body may correspond to multiple potential areas; a potential leakage area may also correspond to multiple components, for example, at least part of the pipe sections of several pipes arranged in parallel correspond to the same potential leakage area. In this embodiment, the leakage detection device has a memory, and a leakage correspondence table is recorded in the memory, and the leakage correspondence table includes a one-to-one correspondence between multiple detection areas of the detection board and multiple potential leakage areas of the product to be detected. Under the setting of this embodiment, the correspondence between multiple detection areas and multiple components of the product to be detected is roughly equivalent to the correspondence between the potential leakage area and multiple components of the product to be detected, which can reduce the background calculation time. As another example, the components of the product to be detected can be divided according to their functions. Taking a washing machine as an example, the drum, water inlet pipe, and water outlet pipe can all be used as an independent potential leakage area.

[0053] In the actual working scenario, the control device obtains the detection signal of each sensor from the detection device by wireless communication, determines whether the sensor is in contact with liquid according to the detection signal of the sensor, and determines that the sensor is a target sensor when the detection information of the sensor indicates contact with liquid, and uses the position information or label of the target sensor as the detection information. In this embodiment, the control device determines the target detection area of ​​the target sensor on the detection board according to the position information or label of the target sensor. According to the preset leakage correspondence table, the potential leakage area of ​​the product to be detected with leakage problem is determined, and the leakage area is the leakage position of the product to be detected, and then determines one or more components of the product to be detected with leakage suspicion. In this embodiment, the interactive device includes a display screen. When the control device determines the leakage position, the control device controls the display screen to display the leakage situation of the product to be detected. The leakage situation includes at least one of the number of leakage positions and the position of the leakage position on the product to be detected. The staff can quickly find the components with leakage problems on the product to be detected according to the leakage situation. In this embodiment, the leakage situation can be expressed in a variety of forms, such as a text list or table for easy record keeping, or a more vivid simulation image, the content of the simulation image includes an image of the bottom of the product to be detected, and the leakage position can be marked with a red mark. In other embodiments, the leakage detection device can also include a voice broadcast device. When the control device determines that the product to be detected has a leakage problem, the control device controls the voice broadcast device to play a voice prompt, and the content of the voice prompt includes at least one of the number of leakage positions and the position of the leakage position on the product to be detected.

[0054] In other embodiments, determining the leakage location according to the detection information includes two steps, and the first step may include: determining the component corresponding to the target sensor as the target component with leakage problem according to the first comparison table, the first comparison table includes a one-to-one correspondence between multiple sensors and multiple components of the product to be detected. After determining the target component, executing the second step, determining the potential leakage area corresponding to the target component according to the second comparison table, the second comparison table includes a correspondence between multiple components and multiple potential leakage areas of the product to be detected.

[0055] In this embodiment, each detection area is provided with a plurality of sub-areas arranged in an array, and the leakage correspondence table may also include a one-to-one correspondence between the plurality of sub-areas and the plurality of components of the product to be detected. The detection range of the sub-area is smaller, and the detection result is more accurate, which can assist workers to accurately find the component with the leakage problem and improve the efficiency of determining the leakage location.

[0056] Under the setting of this embodiment, the control device can determine the detection area of ​​the liquid on the detection plate of the detection device according to the detection information transmitted by the detection device, and can accurately determine the leakage position on the product to be detected based on the detection area, which greatly improves the work efficiency and accuracy of detecting leakage problems of the product to be detected, and can reduce manual participation to reduce labor costs.

[0057] See also Figure 5 The embodiment of the present application also provides another control method for a liquid leakage detection device. The control method for a liquid leakage detection device can be applied to the liquid leakage detection device provided by any of the above embodiments. In the control method, the liquid leakage detection device corresponds and binds multiple detection devices and multiple products to be detected one by one, which is convenient for data sorting and searching. The control method for a liquid leakage detection device provided in the embodiment of the present application includes the following steps S210 to S240.

[0058] Step S210, obtaining product identity information of the product to be tested.

[0059] In the present embodiment, the leakage detection equipment is provided with a plurality of detection platforms, each detection platform is provided with a product to be detected and a detection device, and the leakage of the product to be detected on each detection platform is detected and recorded by a corresponding detection device, so it is necessary to correspond and associate the product to be detected on the same detection platform with the detection device. Specifically, first obtain the product identity information of the product to be detected, the product identity information of the product to be detected can be understood as the "identity card" of the product to be detected, and the leakage detection equipment or staff can determine the corresponding product to be detected according to the product identity information. In the present embodiment, the product identity information of the product to be detected can have a variety of forms of expression, such as a QR code, a bar code, a product order number, a serial number, etc. In the present embodiment, the product identity information of the product to be detected can be obtained in a variety of ways, such as the leakage detection device includes a code scanning device, the code scanning device is electrically connected to the control device, and the code scanning device can scan various types of graphic codes or order numbers printed or pasted on the product to be detected to obtain the product identity information of the product to be detected, and pass it to the control device. For another example, the liquid leakage detection equipment includes an image acquisition device (camera), which can acquire images of various types of graphic codes or order numbers printed or pasted on the product to be inspected, and transmit the image of the product identity information to the control device for identification by the control device. The control device binds the identified product identity information with the corresponding product to be inspected.

[0060] Step 220, obtaining the detection identity information of the detection device, and binding the product identity information with the detection identity information.

[0061] In the present embodiment, each detection device has an "identity card", each detection device has detection identity information, and the identity information of the detection device can have a variety of forms of expression, such as a QR code, a bar code, a product order number, a serial number, etc. In the present embodiment, the detection identity information of the detection device can be obtained in a variety of ways, for example, the leakage detection device includes a code scanning device, the code scanning device is electrically connected to the control device, and the code scanning device can scan various types of graphic codes or numbers printed or pasted on the detection device to obtain the detection identity information of the detection device and pass it to the control device. For another example, the leakage detection device includes an image acquisition device (camera), the image acquisition device can acquire images of various types of graphic codes or numbers printed or pasted on the detection device, and pass the image of the detection identity information to the control device for recognition by the control device, and the control device binds the recognized detection identity information to the corresponding detection device.

[0062] In the case of obtaining the detection identity information of the detection device on the same detection platform and the product identity information of the product to be detected, the product identity information is bound to the detection identity information, so as to establish data connection between the detection device on the same detection platform and the product to be detected. In the present embodiment, there is a storage area in the memory to store a plurality of nodes (such as menu nodes or folder nodes, etc.), and a plurality of nodes correspond to a plurality of detection devices one by one. The detection identity information of the detection device and the product identity information of the product to be detected corresponding to the detection device are stored in a corresponding node (such as stored in the same folder) as sub-node information, so as to realize the binding of the product identity information and the detection identity information. In the present embodiment, the detection result calculated by the detection information of the detection device by the control device can also be stored in the same node as sub-node information, and the detection result can include: whether there is liquid on the detection device, the number of positions where there is liquid on the detection device, the position of liquid on the detection board, the number of leaking positions, the position of the leaking position on the product to be detected, and at least one of the components corresponding to the leaking position. In actual application scenarios, the control device obtains the detection identity information of a detection device, and finds the detection result of the product to be detected corresponding to the detection device in the node where the detection identity information is located; or the control device obtains the product identity information of a product to be detected, and finds the detection result of the product to be detected in the node where the product identity information is located.

[0063] In some other embodiments, the memory also includes a binding comparison table, which includes a one-to-one correspondence between the detection identity information of multiple detection devices and the product identity information of multiple products to be detected. Specifically, the detection identity information of the detection device and the product identity information of the corresponding product to be detected can be recorded in the same (or row or column) cell to achieve the binding of product identity information and detection identity information. In this embodiment, the detection identity information of the detection device, the product identity information of the corresponding product to be detected, and the detection result calculated by the control device through the detection information of the detection device can also be stored in the same (or row or column) cell, and the detection result can include: whether there is liquid on the detection device, the number of positions where liquid exists on the detection device, the position of the liquid on the detection board, the number of leakage positions, the position of the leakage position on the product to be detected, and the components corresponding to the leakage position. In the actual application scenario, when the control device obtains the detection identity information of a detection device, it can determine the detection result of the product to be detected corresponding to the detection device in the binding comparison table; or the control device obtains the product identity information of the product to be detected, and can determine the detection result corresponding to the product to be detected in the binding comparison table.

[0064] Step S230, acquiring detection information from the detection device, where the detection information represents position information of an area where liquid exists on the detection plate.

[0065] Step S240, determining the leakage position according to the detection information, where the leakage position represents the position where the leakage occurs on the product to be detected.

[0066] In this embodiment, the specific implementation of step S230 and step S240 may refer to step S110 and step S120 in the above embodiment, which will not be described in detail in this embodiment.

[0067] Step S250, controlling the interactive device to transmit the detection result to the outside.

[0068] In this embodiment, after calculating the test results, the leakage detection device can promptly transmit the test results to the staff, and the transmission method can be selected according to the type of the interactive device. As an example, the interactive device includes a display screen, and the test results can be displayed on the display screen in the form of a folder or a binding comparison table, and the test personnel can operate on the display screen to find the test results of a product to be tested. In another example, the interactive device can include a voice broadcast device, which can read out the test results to inform the staff.

[0069] In this embodiment, the object to which the test result is transmitted to the outside is not limited to the staff, but can also be other devices. In this embodiment, the liquid leakage detection device can also include a docking conveyor belt, which is connected to the conveyor belt, and the detection plate and the product to be detected can be moved from the conveyor belt to the docking conveyor belt. In this embodiment, the docking conveyor belt at least includes a good conveyor belt and a defective conveyor belt, and the good conveyor belt and the defective conveyor belt are both electrically connected to the control device. The direction of the good conveyor belt and the defective conveyor belt is different. For example, the good conveyor belt is used to transport the product to be detected after the test is completed to the next assembly workshop to further improve the assembly degree of the product to be detected, and the defective conveyor belt is used to transport the product to be detected to the maintenance workshop to disassemble, repair, replace components and other operations on the product to be detected. Based on this, in some embodiments, before, after or at the same time of step S250, the control method of the liquid leakage detection device can also include: controlling the docking conveyor belt to dock with the conveyor belt according to the test result. Specifically, when the test result indicates that there is no water leakage problem in the product to be detected, the good conveyor belt is controlled to dock with the conveyor belt. When the test result indicates that the product to be tested has a water leakage problem, the defective product conveyor belt is controlled to be connected with the conveyor belt.

[0070] Under the setting of this embodiment, the product identity information of the product to be detected and the detection identity information (or detection structure) of the detection device are bound, which is convenient for the leakage detection equipment to find data later. The leakage detection equipment does not need to immediately deal with the product to be detected with a leakage problem. The defective products can be collected first and processed uniformly later. On the one hand, it is beneficial to the overall management of the consumption of various components, warehouse management and cost accounting. On the other hand, it can analyze and calculate based on the detection results of multiple defective products to determine one or more causes of the leakage problem, so as to adjust the production line and improve the product qualification rate.

[0071] See also Figure 6 The embodiment of the present application also provides another control method for a liquid leakage detection device. The control method for the liquid leakage detection device can be applied to the liquid leakage detection device provided by any of the above embodiments. In the control method, the liquid leakage detection device can detect the liquid injection status of the product to be detected, so that the liquid injection status of the product to be detected meets the requirements of the liquid leakage test and improves the reliability of the detection result. The control method for the liquid leakage detection device provided in the embodiment of the present application includes the following steps S310 to S330.

[0072] Step S310, obtaining the liquid injection state of the product to be detected, and when the liquid injection state reaches a preset state, executing the step of obtaining the detection information of the detection device.

[0073] In this embodiment, the preset state of the product to be detected refers to the state in which the liquid content in the product to be detected meets the requirements of the liquid leakage test. In the preset state, the liquid in the product to be detected can reach a certain liquid level, or the liquid in the product to be detected can occupy a certain proportion of the internal space of the product to be detected, and the liquid level or space ratio meets the requirements of the liquid leakage test. As an example, if the product to be detected is a washing machine, the preset state can represent that the depth or liquid level of the liquid in the drum meets the requirements of the liquid leakage test. As another example, if the product to be detected is a pipeline, the preset state can represent that the proportion of the liquid in the pipeline occupying the pipeline space meets the requirements of the liquid leakage test.

[0074] The liquid injection state in this embodiment should be understood as the real-time state of the liquid content inside the product to be detected. The liquid leakage detection device in this embodiment may also include a liquid detection sensor, which is arranged inside the product to be detected to detect the liquid situation inside the product to be detected, and the liquid detection sensor is electrically connected to the control device to transmit information. In this embodiment, the liquid detection sensor may include a water level sensor, which can detect the depth or liquid level of the liquid and transmit it to the control device in real time; the liquid detection sensor may also include a camera, which can obtain the situation inside the product to be detected and transmit it to the control device in real time. In some other embodiments, the liquid detection sensor may be a component included in the product to be detected itself. In such embodiments, the liquid detection sensor and the control device can be wirelessly connected to transmit information. In some other embodiments, the liquid leakage detection device may also include a gravity sensor, which is arranged on the detection board and electrically connected to the control device. The gravity sensor is used to detect the change in the weight of the product to be detected and transmit the data to the control device in real time. When the weight of the product to be detected reaches a certain weight, or the weight growth of the product to be detected reaches a certain degree, it is characterized that the liquid injection state of the product to be detected reaches a preset state.

[0075] In some embodiments, the control device can control the liquid injection device to inject liquid into the product to be detected multiple times. Before step S310, the control method of the leakage detection device can also include: obtaining the time for the liquid injection device to continuously inject liquid into the product to be detected, and when the liquid injection time reaches a preset time, controlling the liquid injection device to stop injecting liquid. In this embodiment, the liquid injection device needs to inject liquid multiple times to make the liquid injection state of the product to be detected reach a preset state. After each liquid injection, the control device obtains the liquid injection state of the product to be detected and the gap between the current liquid injection state and the preset state. According to the gap between the current liquid injection state and the preset state, the time for the next liquid injection is determined, so that the liquid injection state of the product to be detected reaches the preset state more smoothly, avoids excessive liquid injection of the product to be detected, reduces errors in the detection process, and ensures the authenticity and reliability of the detection results.

[0076] In this embodiment, when the signal transmitted by the detection liquid sensor indicates that the liquid injection state inside the product to be detected has reached a preset state, the step of acquiring the detection information of the detection device is performed.

[0077] Step S320, acquiring detection information from the detection device, where the detection information represents position information of an area where liquid exists on the detection plate.

[0078] Step S330, determining the leakage position according to the detection information, where the leakage position represents the position where the leakage occurs on the product to be detected.

[0079] In this embodiment, the specific implementation of step S320 and step S330 may refer to step S110 and step S120 in the above embodiment, which will not be described in detail in this embodiment.

[0080] Under the setting of this embodiment, it can be ensured that when the liquid injection of the product to be tested is completed, the liquid injection condition of the product to be tested is roughly close to the preset state, thereby improving the reliability and accuracy of the test result.

[0081] See also Figure 7 The embodiment of the present application also provides another control method for a liquid leakage detection device. The control method for a liquid leakage detection device can be applied to the liquid leakage detection device provided by any of the above embodiments. In the control method, the liquid leakage detection device can provide cleaning treatment to the detection device and collect the liquid when the detection device is dry to protect the structure of the detection device. The control method for a liquid leakage detection device provided by the embodiment of the present application includes the following steps S410 to S440.

[0082] Step S410, acquiring detection information of the detection device, where the detection information represents position information of an area where liquid exists on the detection plate.

[0083] Step S420, determining the leakage position according to the detection information, where the leakage position represents the position where the leakage occurs on the product to be detected.

[0084] In this embodiment, the specific implementation of step S410 and step S420 may refer to step S110 and step S120 in the above embodiment, which will not be described in detail in this embodiment.

[0085] Step S430: When the detection information indicates that liquid exists on the detection device, control the transport device to transport the detection device on the detection table to a cleaning area.

[0086] In this embodiment, after the detection device completes the water leakage detection of the product to be detected, it is determined whether the detection device needs to be cleaned according to the detection information provided by the detection device. As an example, the detection information indicates that there is liquid on the detection device, which further indicates that the product to be detected corresponding to the detection device has a leakage problem. After the detection is completed, the detection device needs to be cleaned, and then the transport device is controlled to transport the detection device to the cleaning area to receive the cleaning treatment of the cleaning mechanism. Specifically, the control device controls the operation of the cleaning mechanism. In this embodiment, the cleaning mechanism includes a hair dryer, and the hair dryer includes an air pump and an air nozzle that are connected to each other. The air pump can output a strong airflow through the air nozzle toward the detection plate to blow away the liquid on the detection plate. In this embodiment, when the cleaning mechanism is in operation, the control device obtains the detection signals of multiple sensors, and determines whether there is liquid on the detection plate according to the detection signals; when it is determined that there is no liquid on the detection plate, the cleaning mechanism is controlled to stop working. As another example, the detection information indicates that there is no liquid on the detection device, which further indicates that the product to be detected corresponding to the detection device does not have a leakage problem. The detection device does not need to be cleaned after completing the detection. In this case, the control device controls the transport device to transport the detection device to the collection area of ​​the workbench.

[0087] In some embodiments, controlling the transport device to transport the detection device on the detection table to the cleaning area includes three steps. The first step may include: obtaining the position information of the cleaning mechanism. As mentioned above, the cleaning mechanism includes an air pump and an air nozzle. The air pump can output a strong airflow toward the detection plate through the air nozzle to blow away or dry the liquid on the detection plate. In this type of embodiment, an XYZ coordinate system can be established based on the workbench, and the X-axis and Y-axis are located on the plane where the workbench is located. The position information of the cleaning mechanism may include the three-dimensional coordinates of the entire or partial components of the cleaning mechanism in the three-dimensional coordinate system, and the cleaning area and the collection area can be characterized by the three-dimensional coordinates. The position and range of each in the three-dimensional coordinate system. Specifically, in this embodiment, the position information of the cleaning mechanism may include the position information of the air nozzle, and the position information of the air nozzle is characterized by three-dimensional coordinates.

[0088] The second step may include: determining a target cleaning area according to the position information, and the target cleaning area is located in the cleaning area. In this embodiment, the area with strong airflow in the cleaning area (effective range of action) can be determined in combination with the position information of the air nozzle, the output power, the direction of the air nozzle (the conduction direction of the air flow), and the flow rate of the air flow, and the area is defined as the target cleaning area, and the target cleaning area is located in the cleaning area and is part of the cleaning area. In this embodiment, an air pressure threshold can be preset, and the area in the cleaning area where the air pressure value is greater than or equal to the air pressure threshold is divided into the target cleaning area, and the range and position of the cleaning area can be defined by three-dimensional coordinates. In actual application scenarios, the power of the cleaning mechanism, the size and direction of the air nozzle, the position of the air nozzle, etc. can be changed, and the corresponding range and position of the target cleaning area are also changed accordingly.

[0089] The third step may include: according to the target cleaning area, controlling the transport device to transport the detection device to the cleaning area, when the detection device is moved to the cleaning area, an area on the detection device where liquid exists is located above the target cleaning area in the direction of gravity. In this embodiment, after obtaining the position and range of the target cleaning area, the control device can determine the motion trajectory of the transport device in combination with information such as the size of the detection plate of the detection device, the position of the transport device holding the detection plate, and the detection area or sub-area where the liquid is located on the detection plate, and control the transport device to move according to the set motion trajectory to transport the detection device to the cleaning area, and make the liquid or the detection area where the liquid is located or the sub-area where the liquid is located located above the target cleaning area in the direction of gravity to receive cleaning treatment. In the case where there is liquid in multiple places on the detection device, the control device can control the transport device to move multiple areas where liquid exists to the top of the target cleaning area in sequence.

[0090] In this embodiment, the control device can control the transport device to transport the detection device until the liquid on the detection device is within the effective action range of the air nozzle (target cleaning area), so that the cleaning process is more efficient and accurate, ensuring the cleaning effect, avoiding liquid residue, shortening the cleaning time, and avoiding a large number of uncleaned detection devices from being stranded between the conveyor belt and the workbench.

[0091] Step S440, acquiring detection information of the detection device, and when the detection information indicates that there is no liquid on the detection device, controlling the transport device to transport the detection device to the collection area.

[0092] In this embodiment, the cleaning mechanism can provide cleaning treatment to the detection device for multiple times. After the initial cleaning treatment of the detection device is completed, it is necessary to obtain the residual situation of the liquid on the detection plate. The step of obtaining the detection information of the detection device can be performed again. The specific embodiment of this step can refer to step S110 in the above embodiment, and this embodiment will not be repeated.

[0093] After the initial cleaning process, the detection information obtained by the control device again will affect the workflow of the leakage detection device. As an example, the detection information indicates that there is no liquid on the detection device, which means that there is no residual liquid on the detection device, the detection device has been cleaned, and the storage process can be entered. In this case, the control device controls the transport device to transport the detection device from the cleaning area to the collection area. As another example, the detection information indicates that there is liquid on the detection device, which means that there is still residual liquid on the detection device, and the detection device has not been cleaned. After the initial cleaning process, it is necessary to perform cleaning again. In this case, the control device controls the cleaning mechanism to provide cleaning to the detection device again. After the second cleaning process is completed, the step of obtaining the detection information of the detection device is performed again. When the acquired detection information indicates that there is no liquid on the detection device, the transport device is controlled to transport the detection device from the cleaning area to the collection area. If the acquired detection information indicates that there is still liquid on the detection device, the next round of cleaning is performed until the detection device is cleaned.

[0094] In this embodiment, the liquid leakage detection equipment can clean the detection device until the detection device reaches a dry state. On the one hand, it can prevent the liquid from contacting the sensor for a long time and corroding the sensor and the detection circuit, avoid damaging the detection device, and extend the service life of the detection device. On the other hand, the detection device is in a dry state when it is put into the next round of use, preventing liquid from remaining on the detection device and affecting the detection results of the product to be detected, thereby ensuring the accuracy of the detection results.
