Description

Technical Field

[0001] This application relates to a testing fixture for spray assembly, specifically a testing device. Background Technology

[0002] In garment drying devices (dryers, washer-dryer combos), a spray system is typically used to clean dust and lint deposited on the filter screen. The spray sequence is crucial: the system sprays water only when rotating to the filter screen side, and not at other locations. However, during assembly, component damage or improper installation can lead to leaks or incorrect spray sequence, preventing the filter from being properly cleaned. This can cause filter clogging and reduced drying efficiency. Utility Model Content

[0003] In view of this, this application provides a testing device for testing a spray assembly. This testing device is capable of performing functional tests on the spray assembly to ensure that the function of the spray assembly meets the actual use requirements.

[0004] This application is achieved through the following technical solution.

[0005] This application provides a detection device for detecting a spray assembly, comprising: a support member for fixing the spray assembly; at least one first liquid detection component disposed on the support member; and a second liquid detection component disposed on the support member, wherein the first liquid detection component is located at a spray target position of the spray assembly, and the first liquid detection component is disposed downstream of the target position.

[0006] A second liquid detection component is set at the target position of the spray assembly, and at least one first liquid detection component is set downstream of the target position. Based on the detection results of the first liquid detection component and the second liquid detection component, it can be determined whether the spray phase sequence of the spray assembly is correct, thereby determining whether the assembly of the spray assembly is qualified, which is beneficial to improving the yield of the spray assembly.

[0007] In some embodiments, the spray assembly includes a spray element and a filter screen, the filter screen being located between the spray element and the second liquid detection assembly, and water sprayed by the spray element toward the filter screen flowing through the filter screen into the interior of the second liquid detection assembly.

[0008] In some embodiments, the first liquid detection component includes a first blocking member and a first liquid level sensor, the first blocking member forming a first receiving cavity for containing liquid sprayed by the spraying component, and the detection end of the first liquid level sensor being disposed within the first receiving cavity; and / or the second liquid detection component includes a second blocking member and a second liquid level sensor, the second blocking member forming a second receiving cavity for containing liquid sprayed by the spraying component, and the detection end of the second liquid level sensor being disposed within the second receiving cavity.

[0009] A liquid level sensor can detect the volume of liquid inside the blocking component, thereby determining whether the spray assembly should spray water onto the location of the detection component.

[0010] In some embodiments, the detection device includes a control component that is signal-connected to both the first liquid detection component and the second liquid detection component to receive detection information from the first liquid detection component and the second liquid detection component.

[0011] The control component receives detection information from the liquid detection device and then determines whether the spray phase sequence of the spray assembly is correct, thereby improving the automation level of the detection device.

[0012] In some embodiments, the detection device includes a liquid supply assembly for connection to the spray assembly to provide liquid for spraying to the spray assembly. The liquid supply assembly includes: a liquid storage mechanism for storing liquid; and a transmission mechanism, one end of which is connected to the spray assembly and the other end of which is connected to the liquid storage mechanism. The transmission mechanism is used to transmit the liquid in the liquid storage mechanism to the spray assembly.

[0013] The detection device is equipped with a liquid supply component to facilitate the supply of spray liquid to the spraying component.

[0014] In some embodiments, the detection device includes a docking mechanism and a docking drive mechanism. The docking drive mechanism is disposed on the support member, and the drive end of the docking drive mechanism is connected to the docking mechanism. The docking mechanism can rotate between a working position and a retracted position under the drive of the docking drive mechanism. The docking mechanism includes a liquid inlet and a liquid outlet. One end of the transmission mechanism is connected to the liquid inlet of the docking mechanism. When the docking mechanism is in the working position, the liquid outlet is connected to the spray assembly.

[0015] The docking mechanism can rotate between a working position and a retracted position. When liquid needs to be supplied to the spray assembly at the start of the test, the docking mechanism rotates to the working position to connect the outlet to the spray assembly, thereby transferring liquid to the spray assembly. After the test is completed, it rotates to the retracted position, facilitating the installation and removal of the spray assembly.

[0016] In some embodiments, the docking drive mechanism is signal-connected to the control component, and the control component transmits signals to the docking drive mechanism to control the drive component to drive the docking mechanism to rotate.

[0017] The control component transmits signals to the docking drive mechanism, controlling the docking drive mechanism to rotate between the working position and the retraction position, thereby automating the detection device and improving detection efficiency.

[0018] In some embodiments, the detection device includes a seal, which is frame-shaped and abuts against the support and the spray assembly.

[0019] The seal can seal the spray assembly to prevent water sprayed by the spray assembly and water leaking from defective products from flowing out during the testing process and causing the testing device to malfunction.

[0020] In some embodiments, the detection device includes: a clamping mechanism disposed on the support member; the clamping mechanism includes a clamping drive mechanism and a clamping member; the clamping member is connected to the drive end of the clamping drive mechanism; the clamping member is rotatable under the drive of the clamping drive mechanism to clamp and fix the spray assembly; the spray assembly includes a housing and a spraying mechanism fixed to the housing; when the spray assembly is installed on the support member, the clamping member abuts against the housing to tighten and fix the spray assembly to the support member.

[0021] The clamping mechanism secures the spray assembly, facilitating its inspection. The clamping mechanism is rotatable, allowing it to be rotated to either fix the spray assembly in place or to other positions for easy installation and removal.

[0022] In some embodiments, the clamping drive mechanism is signal-connected to the control component, and the control component transmits signals to the clamping drive mechanism to control the clamping drive mechanism to drive the clamping member to rotate in order to fix the spraying assembly to the support member.

[0023] The control component transmits a signal to the clamping drive mechanism, which controls the clamping drive mechanism to drive the clamping member to rotate, thereby fixing the spraying component to the support member, realizing the automation of the detection device and improving detection efficiency.

[0024] In some embodiments, the detection device includes a marking mechanism rotatably disposed on the support member for marking the spray assembly to be tested based on the detection results of the first liquid detection component and the second liquid detection component.

[0025] When the detection results from the first and second liquid detection components indicate that the spray assembly under test is a good product, the marking mechanism can rotate to mark the spray assembly under test. When the detection results from the first and second liquid detection components indicate that the spray assembly under test is a defective product, the marking mechanism can rotate to mark the spray assembly under test.

[0026] In some embodiments, the detection device includes a display component, signal-connected to the control component to display signals received or emitted by the control component.

[0027] The display component can be used to display signals received or sent by the control component, thereby showing the detection results or detection process of the detection device, making it convenient for the operator to view.

[0028] In some embodiments, the detection device includes: a frame, the frame including a first support and a second support arranged along a first direction, the second support being supported on a working surface, the first support being connected to the second support, the support member being disposed on the first support, and the liquid supply assembly being disposed on the second support; and a filter assembly disposed between the first support and the second support.

[0029] The filter assembly is located between the first and second supports to filter out leaking liquid and prevent impurities from contaminating the liquid in the supply section.

[0030] In some embodiments, the detection device includes: a baffle disposed around the edge of the filter assembly, the baffle protruding from the filter assembly in a direction toward the first support along the first direction.

[0031] The baffle can block the liquid flowing out of the spray assembly, preventing the liquid from flowing to the outside of the detection device and causing external environmental pollution.

[0032] In some embodiments, the distance between the first liquid detection component and the plane containing the support is the same as the distance between the second liquid detection component and the plane containing the support. This allows for more accurate detection of whether the spray sequence of the spray assembly is correct. Specifically, if the two distances are different, it cannot be determined whether one of the liquid detection components detected liquid as being sprayed from the spray assembly or leaking from another location.

[0033] In some embodiments, the detection device includes: a rotating detection component disposed on the support member, wherein the detection end of the rotating detection component is disposed opposite to the rotating part of the spraying component.

[0034] The rotation detection component can detect whether the rotating parts in the spray assembly are rotating normally, thereby improving product yield.

[0035] In some embodiments, the first bracket has an opening for operation, and the detection device includes a safety detection component disposed on the first bracket, wherein the sensing range of the safety detection component covers the opening.

[0036] The security detection component's sensing range covers open windows. When an object or person is detected at the open window, an alarm can be triggered, enhancing the security of the detection device.

[0037] The testing device of this application can determine whether the spray phase sequence of the spray assembly is correct, thereby determining whether the assembly of the spray assembly is qualified, which is beneficial to improving the yield of the spray assembly. Attached Figure Description

[0048] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0049] In garment drying appliances (dryers, washer-dryer combos), it's typically necessary to clean dust and lint accumulated on the filter screen. The cleaning process requires precise timing of the water spray from the rotating spray unit; the spray unit should only spray water to clean the filter screen when rotating to that side, and not at other locations. However, during actual assembly, component damage or improper installation can lead to leaks or incorrect spray sequence, preventing the filter from being properly cleaned. This can cause filter clogging and reduced drying efficiency.

[0050] In view of this, this application provides a testing device for testing a spray assembly. This testing device is capable of performing functional tests on the spray assembly to ensure that the function of the spray assembly meets the actual use requirements.

[0051] The detection device provided in this application can be used to detect a spray assembly, including: a support member for fixing the spray assembly; a first liquid detection component disposed on the support member; and at least one second liquid detection component disposed on the support member. The first liquid detection component is located at the spray target position of the spray assembly, wherein the first liquid detection component is disposed downstream of the target position.

[0052] The spray assembly of this application can be a spray assembly in a clothing processing device with a drying function, such as a dryer, washer-dryer combo, or clothing disinfection cabinet, but this application is not limited to this. The spray assembly can be any device used for spraying.

[0053] The spray assembly of this application can be rotatable about its own axis to perform rotary spraying. For example, in a washer-dryer combo, the spray assembly can rotate to rinse the filter.

[0054] In this application, the terms "downstream side" and "downstream side" are defined by the liquid flow in the spray assembly. For example, the spray assembly may have an inlet and an outlet. Liquid flows in from the inlet and out from the outlet. Therefore, the inlet is located upstream of the outlet, and the outlet is located downstream of the inlet.

[0055] A second liquid detection component is set at the target position of the spray assembly, and at least one first liquid detection component is set downstream of the target position. Based on the detection results of the first liquid detection component and the second liquid detection component, it can be determined whether the spray phase sequence of the spray assembly is correct, thereby determining whether the assembly of the spray assembly is qualified, which is beneficial to improving the yield of the spray assembly.

[0056] The rotating spray assembly sprays water when the spray nozzles face the target position, and stops spraying water when the spray nozzles face away from or away from the target position. This spraying procedure is called the spraying sequence, which refers to the spraying timing and order of the spraying assembly.

[0057] Figure 1 A three-dimensional structural schematic diagram of the detection device provided in some embodiments of this application; Figure 2 Schematic diagram of the mounting portion of the detection device provided in some embodiments of this application; Figure 3 A rear-view stereoscopic structural diagram of a detection device provided for some embodiments of this application.

[0058] like Figures 1 to 3 As shown, the detection device 1 may include a frame 100, a first liquid detection component 14, and a second liquid detection component 15. The frame 100 is the support frame of the detection device 1, used to support various functional components that realize the detection device 1. The frame 100 may include, for example, multiple horizontal and vertical frames extending along a first direction, a second direction, and a third direction, respectively, with the multiple horizontal and vertical frames collectively forming the frame 100. In this embodiment of the application, the frame 100 includes a first support 10 and a second support 20 arranged along the first direction. The spray component 2 to be detected can be installed on the first support 10, and the liquid supply component can be installed on the second support 20. The liquid supply component is used to provide the liquid for spraying by the spray component 2.

[0059] like Figure 1 and Figure 3 As shown, the first support 10 and the second support 20 can be arranged in a first direction Y. The first direction Y can be a direction parallel to the direction of gravity, but this application is not limited to this. The second support 20 is supported on a working surface, and the first support 10 is connected to the side of the second support 20 away from the working surface along the first direction. The working surface can be the surface on which the detection device 1 is placed, such as the ground.

[0060] like Figures 1 to 3 As shown, the first bracket 10 may have a support member 110, which is used to install the spray assembly 2, the first liquid detection assembly 14, and the second liquid detection assembly 15, etc. In this embodiment, the support member 110 is generally rectangular in shape, and the flat support member 110 is more conducive to the installation of the spray assembly 2, the first liquid detection assembly 14, and the second liquid detection assembly 15.

[0061] Of course, those skilled in the art should understand that in some other embodiments, the support member 110 may be any other shape, or may be any other structure such as a column. The embodiments of this application do not specifically limit the shape or structure of the support member 110, as long as it can play a good supporting role.

[0062] In this application, a first liquid detection component 14 and a second liquid detection component 15 can be respectively set according to the target position of the spraying component 2. The first liquid detection component 14 can be set to at least one.

[0063] In this application, a second liquid detection component 15 is disposed at a target location of the spray component 2. The target location can be an area, and the second liquid detection component 15 can be disposed at the center of that area. At least one second liquid detection component 15 can be disposed. The second liquid detection component 15 can be disposed upstream of the first liquid detection component 14. Figure 2 As shown, the spray assembly 2 extends in the first direction Y. In some embodiments of this application, the spray assembly 2 may have a housing and spray elements, with the spray elements disposed inside the housing, and the housing fixed to the support member 110.

[0064] Multiple second liquid detection components 15 can be set in different positions, thereby enabling detection in multiple directions. This allows the spraying component 2 to detect whether it is spraying in multiple directions where it should not be spraying, helping the operator to find the cause and location of the malfunction.

[0065] In some embodiments, such as Figures 5 to 7As shown, the spray assembly includes a spray element 230 and a filter screen 210. The filter screen 210 is located between the spray element 230 and the second liquid detection assembly 15. Water sprayed from the spray element 230 toward the filter screen 210 flows through the filter screen 210 and into the interior of the second liquid detection assembly 15. The spray element 230 can be a rotating spray element. When the spray element 230 is rotated so that the spray nozzle is aligned with the filter screen 210, the spray element 230 sprays water, and the water sprayed from the spray element 230 flows through the filter screen 210 and into the interior of the second liquid detection assembly 15. In some embodiments, such as Figure 3 and Figure 4 As shown, the first liquid detection assembly 14 may include a first blocking member 141 and a first liquid level sensor 142. The first blocking member 141 forms a first receiving cavity for receiving liquid sprayed from the spray assembly 2. The detection end of the first liquid level sensor 142 is disposed within the first receiving cavity. The first receiving cavity may have a first opening 140, which connects the first receiving cavity and the internal space of the spray assembly.

[0066] The first liquid level sensor 142 can be a water level sensor. The first liquid level sensor 142 is located downstream of the first blocking member 141 in the first direction Y. The sensing end of the first liquid level sensor 142 can extend into the first receiving cavity to detect the liquid in the first receiving cavity.

[0067] like Figure 2 As shown, the support component 110 includes a power interface 13. The power supply structure of the spray assembly 2 can be connected to the power interface 13 and rotated by starting the internal motor. At this time, the first liquid detection component 14 and the second liquid detection component 15 respectively detect the water flow at the upper and lower water levels of the spray assembly 2 (i.e., the upstream and downstream target positions). According to the normal working logic of the spray assembly 2, there is almost no water flow at the upper water level (second liquid detection component). All the water flow should be the water flow that impacts the filter screen and is discharged from the upper water level (second liquid detection component). At this time, the water flow at the upper and lower water levels is detected by the second liquid level sensor 152 and the first liquid level sensor 142. The detection logic verifies the working logic of the spray assembly 2, and then it is determined to be a qualified product.

[0068] The first liquid level sensor 142 can detect the liquid content in the first containment cavity, and the spray assembly 2 can be determined to be faulty based on the liquid content detected by the first liquid level sensor 142.

[0069] In this application, the second liquid detection assembly 15 includes a second blocking member 151 and a second liquid level sensor 152. The second blocking member 151 forms a second receiving cavity for receiving liquid sprayed from the spray assembly 2. The detection end of the second liquid level sensor 152 is disposed within the second receiving cavity. The filter screen 210 may be configured to cover a second opening 150 of the second receiving cavity. The second receiving cavity may have a second opening 150, which connects the second receiving cavity to the internal space of the spray assembly.

[0070] The second liquid level sensor 152 can be a water level sensor. The second liquid level sensor 152 is located downstream of the second blocking member 151 in the first direction Y. The sensing end of the second liquid level sensor 152 can extend into the second receiving cavity to detect the liquid in the second receiving cavity.

[0071] The second liquid level sensor 152 can detect the liquid content in the second containment cavity, and the spray assembly 2 can be determined as to whether it is malfunctioning based on the liquid content detected by the second liquid level sensor 152.

[0072] As mentioned above, if the spray component 230 functions normally and is installed in the correct position, when the spray component 230 is rotated to the position where the spray nozzle is aligned with the filter screen 210, the water sprayed out by the spray component 230 passes through the filter screen 210 and enters the second receiving cavity through the second opening 150.

[0073] Conversely, if the function or installation position of the spray element 230 is abnormal, such that the spray element 230 cannot be accurately rotated to align the spray nozzle with the filter screen 210, or even if the spray element 230 can be accurately rotated to align the spray nozzle with the filter screen 210 but the water sprayed from the spray nozzle cannot pass through the filter screen 210 and thus cannot enter the second receiving cavity, the water sprayed from the spray element 230 will flow to the first liquid detection component 14 downstream of the second liquid detection component 15 and enter the first receiving cavity through the first opening 140.

[0074] Because the first receiving cavity contains a first liquid level sensor 141, which can measure the liquid content inside the first receiving cavity. The second receiving cavity contains a second liquid level sensor 152, which can measure the liquid content inside the second receiving cavity. If the spray components are installed correctly and the spray phase sequence is normal, the sprayed liquid will enter the second receiving cavity and will not enter the first receiving cavity.

[0075] Based on the liquid content inside the first and second receiving cavities, it can be determined whether the installation of the spraying component and the spraying sequence are normal. Specifically, when the spraying component is installed correctly and the spraying sequence is normal, the liquid content inside the first receiving cavity is lower than a first threshold, while the liquid content inside the second receiving cavity is higher than a second threshold. The range of the first and second thresholds can be determined based on the liquid content sprayed by the spraying component in a single operation. For example, if the spraying component sprays 10 ml of liquid in a single operation, the first threshold can be 0.5 ml, and the second threshold can be 9.5 ml.

[0076] If the installation of the spray components or the spray phase sequence is completely reversed compared to the normal situation, the liquid content inside the first receiving cavity may be higher than the second threshold, while the liquid content inside the second receiving cavity may be lower than the first threshold.

[0077] If the installation of the spray components or the spray sequence causes the spray range of the spray nozzle to cover part of the filter screen, the liquid content in the first receiving chamber may be similar to that in the second receiving chamber.

[0078] If the spraying component fails to spray at all, the liquid content in both the first and second accommodating cavities may be lower than the first threshold.

[0079] It should be noted that those skilled in the art can use the above logic to refer to the liquid content in the first accommodating cavity and the liquid content in the second accommodating cavity to deduce various abnormal situations, thereby determining whether the spray assembly is normal and the cause of the abnormality of the spray assembly.

[0080] In this application, a liquid level sensor can detect the volume of liquid inside the blocking component, thereby determining whether the spray assembly should spray water onto the location of the detection component.

[0081] In some embodiments, the detection device 1 may include a control component 30, which may be disposed on the first bracket 10. However, this application is not limited to this. In some embodiments, the control component 30 may also be disposed on the second bracket 20, or the control component 30 may not be disposed on the rack. The control component 30 may be signal-connected to both the first liquid detection component 14 and the second liquid detection component 15. In some embodiments of this application, the control component 30 may be electrically connected, Bluetooth connected, antenna signal connected, WiFi signal connected, etc., to the first liquid detection component 14 and the second liquid detection component 15. This application does not limit the connection method of the control component 30 with the first liquid detection component 14 and the second liquid detection component 15, as long as information transmission is possible.

[0082] like Figure 1 and Figure 3As shown, the control component 30 can be disposed at the top of the first bracket 10 in the first direction Y. The control component 30 can be an electrical control box.

[0083] The first blocking member 141 may have a mounting plate 19, which partially intercepts the water flow that affects the detection. The remaining water flow reaches the first liquid detection component 14 and the second liquid detection component 15 respectively. The water flow is detected by the first liquid level sensor 142 and the second liquid level sensor 152. At the same time, the control component 30 is placed above the detection device 1 to prevent safety problems such as short circuits caused by water leakage.

[0084] The first liquid detection component 14 can transmit the detected water level information to the control component 30. The control component 30 may have a processing unit, which can determine whether the spraying situation at the target location is normal based on the received water level information.

[0085] The second liquid detection component 15 can transmit the detected water level information to the control component 30. The control component 30 may have a processing unit, which can determine whether the spraying situation at the upstream side of the target location is normal based on the received water level information.

[0086] The control component 30 receives the detection information from the liquid detection device and then determines whether the spray phase sequence of the spray assembly is correct, thereby improving the automation level of the detection device.

[0087] The control component 30 can output corresponding control signals based on the target position obtained by the processing unit and the spraying situation at the position upstream of the target position. For example, the detection device 1 can have an alarm device, and the control component 30 can control the alarm device to sound an alarm if the spraying situation is abnormal, so that the operator can handle it in time.

[0088] In some embodiments, such as Figure 2 As shown, the detection device 1 may include a marking mechanism 16, which may be rotatably disposed on the support member 110 for marking the spray assembly 2 to be tested according to the detection results of the first liquid detection component 14 and the second liquid detection component 15.

[0089] When the detection results from the first and second liquid detection components indicate that the spray assembly under test is a good product, the marking mechanism can rotate to mark the spray assembly under test. When the detection results from the first and second liquid detection components indicate that the spray assembly under test is a defective product, the marking mechanism can rotate to mark the spray assembly under test.

[0090] In some embodiments, the marking mechanism may have multiple marking surfaces or marking elements, and different marking surfaces may be used to mark good or defective products, and different marking elements may be used to mark good or defective products. However, this application is not limited to this. In some embodiments, the marking mechanism may be used only to mark defective products, or the marking mechanism may be used only to mark good products.

[0091] In this application, the marking mechanism 16 can be signal-connected to the control component 30. When the processing unit of the control component 30 detects that the spraying condition of the spraying component 2 is normal, it outputs a control signal to the marking mechanism 16 to mark the spraying component under test as a good product. Conversely, when the processing unit of the control component 30 detects that the spraying condition of the spraying component 2 is abnormal, it outputs a control signal to the marking mechanism 16 to mark the spraying component under test as a defective product. However, this application is not limited to this; in some embodiments, the marking mechanism 16 can also be manually controlled for marking.

[0092] In some embodiments, such as Figure 1 and Figure 3 As shown, the detection device 1 may include a display component 40, which may be signal-connected to the control component 30 to display signals received or sent by the control component 30.

[0093] The display component can be used to display the signals received or sent by the control component 30, thereby displaying the detection results or detection process of the detection device, which is convenient for the operator to view.

[0094] In this application, when the processing unit of the control component 30 detects that the spraying condition of the spraying component 2 is normal, it outputs corresponding information to the display component 40 to display good products on the display component 40. Conversely, when the processing unit of the control component 30 detects that the spraying condition of the spraying component 2 is abnormal, it outputs corresponding information to the marking mechanism 16 to display defective products on the display component 40.

[0095] In this application, the control component 30 is signal-connected to the display component 40 to transmit the detection result of the first liquid detection component 14 to the display component 40 for display, and the control component 30 is signal-connected to the display component 40 to transmit the detection result of the second liquid detection component 15 to the display component 40 for display. Thus, the operator can judge whether the spraying status of the spraying component 2 is normal based on the information displayed on the display component 40.

[0096] In this application, the control component 30 may be omitted. Instead, the first liquid detection component 14 is connected to the display component 40 to transmit the detection result of the first liquid detection component 14 to the display component 40 for display, and the second liquid detection component 15 is connected to the display component 40 to transmit the detection result of the second liquid detection component 15 to the display component 40 for display. Thus, the operator can judge whether the spraying status of the spraying component 2 is normal based on the information displayed on the display component 40.

[0097] In some embodiments, such as Figure 1 and Figure 3 As shown, the detection device 1 may include a liquid supply assembly, which can be connected to the spray assembly 2 to supply liquid for spraying to the spray assembly 2. The liquid supply assembly may include a liquid storage mechanism 21 and a transfer mechanism 22. The liquid storage mechanism 21 is used to store liquid. One end of the transfer mechanism 22 is connected to the spray assembly 2, and the other end is connected to the liquid storage mechanism 21. The transfer mechanism 22 is used to transfer the liquid in the liquid storage mechanism 21 to the spray assembly 2.

[0098] In this application, the transmission mechanism 22 may include a transmission pipe and a water pump. The transmission pipe is connected to the water pump and the spray assembly 2 respectively to transmit the liquid in the liquid storage mechanism 21 to the spray assembly 2.

[0099] The detection device is equipped with a liquid supply component to facilitate the supply of spray liquid to the spraying component.

[0100] In some embodiments, such as Figure 2 As shown, the detection device 1 may include a docking mechanism 12 and a docking drive mechanism, with the docking drive mechanism mounted on the support member. The docking drive mechanism may be a motor, cylinder, etc. The drive end of the docking drive mechanism may be connected to the docking mechanism, and the docking mechanism 12 (docking structure) may rotate between the working position and the retraction position under the drive of the docking drive mechanism.

[0101] The docking mechanism 12 includes an inlet and an outlet. One end of the transmission mechanism is connected to the inlet of the docking mechanism 12. When the docking mechanism is in the working position, the outlet is connected to the spray assembly 2. The liquid in the storage mechanism 21 is fed into the spray assembly 2 via the docking mechanism 12 for spraying.

[0102] The docking mechanism can rotate between a working position and a retracted position. When supplying liquid to the spray assembly, it rotates to the working position to connect the outlet to the spray assembly and transfer liquid to it. This rotatable design allows the docking mechanism to both supply liquid to the spray assembly and rotate to the retracted position, facilitating the installation and removal of the spray assembly.

[0103] In some embodiments, the docking drive mechanism is signal-connected to the control component 30, and the control component 30 transmits signals to the docking drive mechanism to control the drive component to drive the docking mechanism to rotate. For example, the control component 30 can output a control signal to the docking drive mechanism to control the docking drive mechanism to rotate to the working position based on the fact that the spray assembly 2 has been installed on the support member 110.

[0104] Regarding the signal indicating whether the control component 30 is installed on the support member 110, the detection device 1 may include a sensor that detects whether the spray assembly 2 is installed on the support member. This sensor transmits the signal indicating that the control component 30 is installed on the support member 110 to the control component 30. In this application, the first bracket 10 may have an indicator panel 41, which may be located at the top of the first bracket 10 in the first direction Y. This facilitates connection between the indicator panel 41 and the control component 30. The indicator panel 41 may include indicator lights, indicator buttons, etc. The indicator lights and indicator buttons can be signal-connected to the control component 30, and manual operation of the indicator buttons can transmit installation information of the spray assembly 2 to the control component 30.

[0105] The control component 30 can control the docking drive mechanism to rotate the docking mechanism 12 to the retraction position according to the signal such as the end or stop of the detection program, so as to facilitate the removal of the spray assembly 2.

[0106] The control component 30 transmits signals to the docking drive mechanism, controlling the docking drive mechanism to rotate between the working position and the retraction position, thereby automating the detection device and improving detection efficiency.

[0107] In some embodiments, such as Figure 2 As shown, the detection device 1 may include a seal 17, which may be frame-shaped and may abut between the support 110 and the spray assembly 2. The seal 17 may be a material or component with cushioning properties or a certain degree of deformation, such as silicone, plastic, or foam.

[0108] The seal 17 can seal the spray assembly 2 to prevent the water sprayed by the spray assembly 2 and the water leaked from defective products during the testing process from flowing out and causing the testing device to malfunction.

[0109] In some embodiments, such as Figures 1 to 3 As shown, the detection device 1 may include a clamping mechanism 11, which is rotatably mounted on the support member 110. The clamping mechanism 11 may have a docking drive mechanism and grippers, the grippers being used to abut against the spray assembly 2 to fix the spray assembly 2. The docking drive mechanism is used to drive the grippers to rotate between a working position and a retracted position.

[0110] The docking drive mechanism can be a motor, cylinder, etc. The drive end of the docking drive mechanism can be connected to the gripper, and the gripper can rotate between the working position and the retracted position under the drive of the docking drive mechanism.

[0111] In some embodiments, the docking drive mechanism is signal-connected to the control component 30, and the control component 30 transmits signals to the docking drive mechanism to control the rotation of the driving gripper. For example, the control component 30 can output a control signal to the docking drive mechanism to control the driving gripper to rotate to the working position to fix the spray assembly 2, based on the fact that the spray assembly 2 has been placed on the support member 110.

[0112] The spray assembly 2 may include a housing and spray elements fixed to the housing. When the spray assembly is mounted on the support 110, the clamping mechanism 11 abuts against the housing to fix the spray assembly to the support 110.

[0113] The clamping mechanism 11 is used to fix the spray assembly, facilitating the inspection of the spray assembly. The clamping mechanism 11 is rotatable, and can be rotated to fix the spray assembly or to other positions, facilitating the installation and removal of the spray assembly.

[0114] like Figure 1 and Figure 2 As shown, multiple clamping mechanisms 11 can be configured, and multiple clamping mechanisms 11 can more tightly fix the spray assembly 2 to the support. Figure 1 and Figure 2 As shown, the spray assembly 2 can extend in the first direction Y, and multiple clamping mechanisms 11 can be symmetrically arranged in the second direction X. However, this application does not limit the number or arrangement of the clamping mechanisms, as long as they can fix the spray assembly.

[0115] In some embodiments, the clamping mechanism 11 is signal-connected to the control component 30, and the control component 30 transmits signals to the clamping mechanism to control the clamping mechanism component to rotate in order to fix the spraying component and the support member 110.

[0116] The control component 30 transmits a signal to the clamping mechanism to control the clamping mechanism to rotate and fix the housing and the support, thereby automating the detection device and improving detection efficiency.

[0117] In some embodiments, the detection device 1 may include a filter assembly 31, which may be disposed between the first support 10 and the second support 20 to filter liquid flowing from the spray assembly 2. The filter assembly 31 may be a filter screen.

[0118] The filter assembly 31 is located between the first support 10 and the second support 20 to filter out leaking liquid and prevent impurities from contaminating the liquid in the supply section.

[0119] In some embodiments, the detection device 1 may include a baffle 32, which may be disposed on the filter assembly 31 to block liquid flowing out from the mounting portion. The baffle 32 may be disposed around the edge of the filter assembly 31, for example, the baffle 32 may be disposed around the periphery of the filter assembly 31. In some embodiments of this application, the first support 10 may have a window 111 through which an operator can operate and observe. With the opening of the window 111 facing outwards, and one side of the filter assembly 31 located inside the first support 10, this side may be the side closer to the support member, and the baffle 32 may be located on a side other than this side.

[0120] The baffle 32 can block the liquid flowing out from the mounting part, preventing the liquid from flowing to the outside of the detection device and causing external environmental pollution.

[0121] In some embodiments, the distance between the first liquid detection component 14 and the plane containing the support 110 is the same as the distance between the second liquid detection component 15 and the plane containing the support 110. For example... Figure 4 As shown, the distances of the first liquid detection component 14 and the second liquid detection component 15 relative to the support member 110 in the third direction Z are the same.

[0122] Therefore, it is possible to more accurately detect whether the spray phase sequence of the spray assembly is correct. Specifically, if the two distances are different, it cannot be determined whether one of the liquid detection components detected that the liquid was sprayed from the spray assembly or leaked from another location.

[0123] like Figure 3 and Figure 4 As shown, the first bracket 10 may have a side stop 120, which is disposed on the support member 110 in the third direction Z. The side stop 120 is disposed on the side of the support member 110 away from the window 111 in the third direction Z. The side stop 120 may be disposed on the side of the first liquid detection assembly 14 and the second liquid detection assembly 15 to block liquid. The side stop 120 may be configured as a pair, and the pair of side stop 120 may be disposed opposite to each other in the second direction X.

[0124] In this application, the first direction Y, the second direction X, and the third direction Z can intersect each other; for example, the intersections of the first direction Y, the second direction X, and the third direction Z can be perpendicular to each other. The support member 110 extends in the plane defined by the first direction Y and the second direction X.

[0125] In some embodiments, such as Figure 2As shown, the detection device 1 may further include a rotating detection component 18, which is disposed on the support member 110 and whose detection end is opposite to the rotating component 220 of the spray assembly 2. The rotating component 220 is sleeved on the spray component 230 and rotates together with the spray component 230.

[0126] The rotation detection component 18 can detect whether the rotating part 220 in the spray assembly is rotating normally, improving product yield. For example, the rotating part 220 may have multiple metal fasteners (e.g., screws, etc.). The rotation detection component 18 is fixedly installed and can detect the time interval between the rotation of two adjacent metal fasteners to determine whether the spray assembly is rotating normally. The rotation detection component 18 can be electrically connected to the control component 30 to transmit signals to the control component 30.

[0127] For a rotatable spray component, the control component 30 makes a comprehensive judgment on whether the spray component 230 is rotating normally and spraying normally based on the results from the rotation detection component 18, the first liquid detection component 14, and the second liquid detection component 15.

[0128] If the rotation detection component 18 detects that the rotation of the spray component 230 is normal, the liquid content inside the first receiving cavity is lower than the first threshold, while the liquid content inside the second receiving cavity is higher than the second threshold.

[0129] If the rotation detection component 18 detects that the rotation of the spray component 230 is too fast or too slow, the liquid content in the first receiving chamber may be similar to that in the second receiving chamber.

[0130] If the rotation detection component 18 detects that the spray component 230 cannot rotate, the liquid content inside the first receiving cavity may be higher than the second threshold, while the liquid content inside the second receiving cavity may be lower than the first threshold.

[0131] In some embodiments, the first bracket 10 may have an opening 111 for operation, and the detection device includes a safety detection component 33, which may be disposed on the mounting portion and whose sensing range covers the opening.

[0132] The safety detection component's sensing range covers the open window. When it detects an object or person at the open window, it can issue an alarm, enhancing the safety of the detection device. The safety detection component 33 can be electrically connected to the control component 30 to transmit signals. When the safety detection component 33 detects an object or person at the open window, the control component 30 can control the indicator lights or prompting elements on the indicator panel 41 to alert the operator. The control component 30 can also provide prompts through the display component 40.

[0133] In this application, the safety detection component can be a safety grating (grating sensor).

[0134] like Figure 1 , Figure 2 and Figure 4 As shown, the testing device 1 may include casters 23 and feet 24 disposed at the bottom of the frame 100 in the first direction Y. Adjustable feet 24 are fixed at the four corners of the lower end of the frame 100 to facilitate equipment height adjustment. Movable casters 23 are simultaneously fixed at the bottom of the frame 100. By adjusting the height of the feet 24, the equipment can be moved using the casters 23 to facilitate equipment position adjustment.

[0135] In some embodiments of this application, those skilled in the art can manually place the rotary spray assembly onto the silicone sealing positioning seat (sealant), the silicone sealing positioning seat is installed on the back plate (support) of the rotary spray assembly positioning and pressing system, manually connect the power interface of the rotary spray assembly, manually press the start button 4, the equipment starts, the safety light curtain starts, the indicator lights and emergency stop button (indicator lights and buttons on the indicator panel) light up, and the rotary clamping cylinder assembly (clamping mechanism) starts to clamp the rotary spray assembly onto the silicone sealing positioning seat.

[0136] In this embodiment, after the spray assembly is installed, the water inlet docking cylinder assembly (docking mechanism) extends to dock the water inlet with the water inlet of the rotary spray assembly, the LED lighting strip 5 is turned on to facilitate manual observation of the actual water output, and the water pump in the water tank (liquid storage mechanism) is started to pump water from the water tank to the rotary spray assembly.

[0137] After the docking mechanism connects with the spray assembly, the motor inside the rotary spray assembly starts rotating. This startup can be achieved by the upper water level baffle (second liquid detection assembly) and lower water level baffle (first liquid detection assembly) controlling the water flow at the upper and lower water levels of the rotary spray assembly, respectively. According to the normal operating logic of the rotary spray assembly, there should be almost no water flow at the lower water level; all the water should impact the filter screen and be discharged from the upper water level. At this time, the water flow at the upper and lower water levels is detected by the upper water level flow sensor (second liquid level sensor) and the lower water level flow sensor (first liquid level sensor). If the detection logic matches the operating logic of the rotary spray assembly, it is judged as a qualified product. When a qualified product is determined, the indicator light and emergency stop button light up green, and the display component shows that the spray assembly under test is a good product. The good product stamping cylinder assembly (marking assembly) starts, stamps the product, and the rotary clamping cylinder assembly rotates and retracts. The power interface of the rotary spray assembly is disconnected manually, and the rotary spray assembly is removed manually. This completes the entire testing process.
