[0028] This specification provides an apparatus (hereinafter referred to as the apparatus) for batch measurement of the water resistance and airtightness of products, as exemplified by some embodiments. Figure 1 As shown, the device 100 includes a production line 110 and an openable cavity 120. The production line 110 includes a drive unit (not shown) and a transmission assembly 111, which is connected to the drive unit and configured to transport the product 200 to be tested. The openable cavity 120 is disposed on the production line 110 and is provided with a vision recognition component 121, a pneumatic control component 122, an air inlet 123, and an air outlet 124, which communicates with the pneumatic control component 122.

[0029] The assembly line, also known as a production line, is a form of production organization that enables continuous operation to improve efficiency and reduce costs.

[0030] A drive element is a device or apparatus used to provide power so that equipment or machinery can operate in a intended manner. Exemplary drive elements include, but are not limited to, electric motors.

[0031] The transmission assembly 111 refers to a mechanism or device for conveying the product 200 to be tested. In some embodiments, the transmission assembly may include a conveyor belt 1111, a driving pulley (not shown), and a driven pulley (not shown).

[0032] The conveyor belt 1111 can be used to carry and transport the product under test 200. In some embodiments, the conveyor belt 1111 can be used to transport multiple batches of the product under test 200.

[0033] In some embodiments, the output shaft of the drive unit can be connected to the drive wheel of the transmission assembly 111 to drive the conveyor belt 1111 to transport the product under test 200.

[0034] The product under test 200 refers to a product that requires testing or measurement of its waterproofness and airtightness. In some embodiments, the product under test 200 is made of a flexible material. Exemplary flexible materials include, but are not limited to, rubber, silicone, polyethylene (PE), polypropylene (PP), etc.

[0035] In some embodiments, the product under test 200 may include a silicone toy speaker. In some embodiments, the product under test 200 may be any other flexible material product that requires testing or measurement of waterproofness and airtightness.

[0036] In some embodiments, the production line 110 may also include a mounting bracket (not shown). The mounting bracket can be used to support and mount the transmission assembly 111 so that the transmission assembly 111 can better and more stably transport the product under test 200.

[0037] The openable cavity 120 refers to a cavity structure disposed on the assembly line body 110 and capable of being opened and closed. In some embodiments, the structural shape of the openable cavity 120 includes, but is not limited to, a rectangular shape, a trapezoidal shape, a cylindrical shape, etc.

[0038] In some embodiments, the openable cavity 120 may be disposed on the assembly line body 110 (such as a mounting bracket), and the conveyor belt 1111 may pass through the openable cavity 120 to realize the transport of the product 200 to be tested.

[0039] In some embodiments, at least the upper surface of the openable cavity 120 is made of a transparent material. Exemplary transparent materials may include quartz glass, acrylic, polycarbonate (PC), etc.

[0040] The upper end face of the openable cavity 120 refers to the end face of the openable cavity 120 away from the conveyor belt 1111. In some embodiments, the upper end face of the openable cavity 120 is made of a transparent material (such as glass). In some embodiments, the upper end face and one or more other end faces of the openable cavity 120 may be made of a transparent material.

[0041] Understandably, by making at least the upper surface of the openable cavity 120 transparent, it is easy to place the visual recognition component on the outer side of the upper surface of the openable cavity 120, thereby effectively avoiding damage to the product under test (such as avoiding damage to the product under test when spraying and drying) without affecting the visual recognition component's ability to photograph the product under test.

[0042] In some embodiments, the openable cavity 120 is covered at least on its upper surface with a nano-coating, the nano-coating being made of at least one of zirconium oxide (ZrO2), aluminum oxide (Al2O3), and silicon oxide (SiO2).

[0043] In some embodiments, when the upper surface of the openable cavity 120 is made of a transparent material (such as glass), a nano-silica layer can be covered on the inner side of the surface to prevent fogging and ensure the transparency of the openable cavity 120.

[0044] In some embodiments, when the upper end face of the openable cavity 120 is made of a transparent material (such as glass), a nano-zirconia layer or a nano-alumina layer can be covered on the outside of the end face to enhance its toughness and crack resistance and prevent the openable cavity 120 from cracking.

[0045] In some embodiments, when the upper surface of the openable cavity 120 is made of a transparent material (such as glass), a nano-coating can be simultaneously applied to both the inner and outer sides of the surface to improve its toughness and crack resistance while maintaining the transparency of the openable cavity 120. It should be noted that when the upper surface of the openable cavity 120 and one or more other surface surfaces are made of transparent materials (such as glass), a nano-coating can be applied to the inner and / or outer sides of each surface.

[0046] The visual recognition component 121 refers to a device or apparatus used to photograph the product 200 under test within the openable cavity 120. For example, the visual recognition component 121 may include a camera, a webcam, etc.

[0047] In some embodiments, the visual recognition component 121 may be disposed at the central position on the outer side of the upper end face of the openable cavity 120, so as to better capture images of the product 200 under test inside the openable cavity 120. For example... Figure 1 As shown, the visual recognition component 121 can capture images of a group of test products 200 that enter the openable cavity 120. Each group contains the same number of test products 200.

[0048] The pneumatic control assembly 122 refers to a device or apparatus used to evacuate the openable cavity 120 in order to control the pneumatic pressure inside the openable cavity 120.

[0049] In some embodiments, the pressure control component 122 includes a vacuum pump.

[0050] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container (such as an openable cavity 120) to obtain a vacuum.

[0051] In some embodiments, a vacuum pump can evacuate the openable cavity 120 by communicating with the vent 124, thereby changing the air pressure inside the openable cavity 120 and creating a vacuum inside the openable cavity 120. Understandably, when the vacuum pump is operating, the vent 123 should be in a closed or shut-off state.

[0052] It should be noted that the air pressure control component 122 can also be any other feasible device or apparatus that can control the air pressure inside the openable cavity 120.

[0053] The air inlet 123 is a perforated structure for allowing outside air to enter the openable cavity 120. The air outlet 124 is a perforated structure for discharging air from the openable cavity 120 to the outside. In some embodiments, the diameters of the air inlet 123 and the air outlet 124 can be set according to actual application requirements.

[0054] In some embodiments, as Figure 1 As shown, the air inlet 123 and the air outlet 124 can be disposed on the upper end face of the openable cavity 120. In some embodiments, the air inlet 123 and the air outlet 124 can also be disposed at any other feasible position on the openable cavity 120, without any limitation.

[0055] In some embodiments, the testing personnel can close the air inlet 123 and open the air pressure control component 122 to evacuate the air from the openable cavity 120, causing the air pressure inside the openable cavity 120 to drop until a vacuum is formed. At this time, the multiple test products 200 located in the openable cavity 120 will deform (e.g., expand) due to their own internal and external pressure difference. Then, the visual recognition component 121 is used to take pictures of the multiple test products 200 located in the openable cavity 120 to obtain an image of the test product 200 in a vacuum state (hereinafter referred to as the initial image).

[0056] Then, the testing personnel turn off the air pressure control component 122 and open the air inlet 123, and then use the visual recognition component 121 to take multiple pictures of the multiple products 200 to be tested located in the openable cavity 120 to obtain secondary images of the products 200 to be tested.

[0057] Finally, the testing personnel can determine the waterproofness and airtightness of the product under test 200 by comparing the degree of contour deformation in the initial image and the secondary image. For example, the product under test 200 with a smaller degree of deformation has poor waterproofness and airtightness, and may have leaked air.

[0058] For more information on devices for batch measurement of product water resistance and airtightness, please refer to the relevant description below.

[0059] In some embodiments of this specification, the device for batch measuring the waterproofness and airtightness of products includes a production line and an openable cavity. The production line can transport multiple products to be tested in batches, while the openable cavity is equipped with a visual recognition component and a pneumatic control component. Through the coordinated operation of the pneumatic control component and the visual recognition component, the waterproofness and airtightness of multiple products to be tested can be measured in batches, thereby improving measurement efficiency.

[0060] In some embodiments, the device 100 further includes a sensing component (not shown) and a processing component (not shown). The processing component is electrically connected to the drive component, the vision recognition component 121, the pneumatic control component 122, and the sensing component.

[0061] A sensing component refers to a sensing element used to acquire distance data. For example, a sensing element may include a displacement sensor.

[0062] Distance data can reflect the distance between the sensing component and the product under test 200. In some embodiments, there can be multiple sensing components, which are respectively disposed on the inner peripheral surface of the openable cavity 120 to acquire distance data in multiple directions.

[0063] A processing component refers to a device used to process information and / or data, and to uniformly manage and control multiple devices to achieve collaborative operation. The processing component can execute program instructions based on this data, information, and / or processing results to perform one or more functions described in this application. In some embodiments, the processing component may include one or more sub-processing devices (e.g., a single-core processing device or a multi-core multi-chip processing device). By way of example only, the processing component may include a central processing unit (CPU), a controller, a microprocessor, or any combination thereof.

[0064] In some embodiments, the processing component can be used to control the operation of the drive unit, the visual recognition component 121, and the air pressure control component 122 respectively based on distance data.

[0065] In some embodiments, the processing component may control the drive to pause operation based on distance data. For example, the processing component may control the drive to pause operation in response to distance data being within a preset range, so as to facilitate waterproofing and airtightness testing of the product 200 under test.

[0066] In some embodiments, the processing component may also, in response to the suspension of the drive unit, control the pneumatic control component 122 to evacuate the openable cavity 120 at a preset evacuation rate (at which time the air inlet 123 is closed or shut down), and continue for a preset period of time until the openable cavity 120 is in a vacuum state and then stops working. In some embodiments, the preset evacuation rate and the preset period of time may be preset by the testing personnel based on historical data, past experience, etc.

[0067] In some embodiments, the processing component may also control the visual recognition component 121 to take a picture of the product under test 200 inside the openable cavity 120 in response to the air pressure control component 122 completing the air extraction for a preset time period, thereby obtaining an initial image of the product under test 200.

[0068] In some embodiments, the processing component can also be used to determine the water resistance and air tightness of the product under test 200. Further details on how the processing component determines the water resistance and air tightness of the product under test can be found in the relevant description below.

[0069] In some embodiments of this specification, by setting up a sensing component and a processing component, the processing component controls other components (such as driving components) to work together based on the distance data acquired by the sensing component, making the device more automated and intelligent, and effectively improving the detection efficiency of batch measurement.

[0070] In some embodiments, the device 100 further includes a display component (not shown) and a warning device. Both the display component and the warning device are electrically connected to the processing component.

[0071] A warning device is a component used to alert testing personnel. In some embodiments, the processing component can control the warning device to issue a warning in response to the test product's water resistance and airtightness falling below preset values ​​in the measurement results. The warning method can be a warning light, a warning sound, etc.

[0072] A display component refers to a device or apparatus used to display measurement results. For example, a display component includes, but is not limited to, a display screen. In some embodiments, a processing component can send measurement results to the display component for display. The content displayed by the display component may include the distribution locations of the tested products whose waterproofness and airtightness are below preset values.

[0073] Understandably, setting up an early warning system helps to promptly remind testing personnel to reject substandard products (those with poor waterproofing and airtightness). Furthermore, by setting up a display component to show the location of substandard products to testing personnel, it helps them to find and reject substandard products more quickly, thereby ensuring the product yield rate.

[0074] In some embodiments, both the air inlet 123 and the air outlet 124 are provided with regulating valves (not shown in the figure).

[0075] A regulating valve is a valve used to control the rate at which air enters or exits the openable / closed cavity 120. In some embodiments, the regulating valve can be used to control the air intake rate of the air inlet 123 and the air exhaust rate of the air outlet 124. The exhaust rate is positively correlated with the degree of opening of the regulating valve; the greater the degree of opening of the regulating valve, the greater the exhaust rate.

[0076] In some embodiments, the control valve may be a solenoid valve. In some embodiments, the control valve may be electrically connected to the processing component.

[0077] In some embodiments, the processing component may, in response to the suspension of the drive unit, control the regulating valve located in the air inlet 123 to close (i.e., the air inlet 123 is closed or shut off), and control the regulating valve located in the air outlet 124 to open, so that the air outlet 124 exhausts air at a preset exhaust rate. In some embodiments, the preset exhaust rate may be set in advance by the testing personnel based on historical data.

[0078] In some embodiments, the processing component may also, in response to the visual recognition component 121 completing the capture of an initial image of the product 200 under test, control the regulating valve located in the air inlet 123 to open so that the air inlet 123 allows air to enter at a preset air intake rate, and control the regulating valve located in the air outlet 124 to close (i.e., the air outlet 124 is closed or shut down). In some embodiments, the preset air intake rate may be set in advance by the testing personnel based on historical data.

[0079] In some embodiments, the processing component may also respond to the opening of the regulating valve in the air inlet 123 to allow air to enter through the air inlet 123 at a preset air intake rate, and the closing of the regulating valve in the air outlet 124, by controlling the visual recognition component 121 to capture images of the product under test 200 within the openable cavity 120 at a preset frequency, thereby obtaining a secondary image of the product under test 200. The preset frequency refers to the acquisition frequency of the visual recognition component 121. In some embodiments, the preset frequency may be set in advance by the testing personnel.

[0080] It should be noted that the regulating valve can also be manually adjusted by the testing personnel according to the actual situation.

[0081] Understandably, after the visual recognition component 121 completes the second image capture of the product under test 200, the processing component can simultaneously start the driving unit to operate at a preset driving power. The preset driving power can be set in advance by the testing personnel.

[0082] In some embodiments described in this specification, regulating valves are installed in the air inlet and outlet to adjust the air intake or exhaust rate. This effectively prevents product damage that may be caused by rapid changes in air pressure within the openable cavity, thus helping to ensure product quality. Simultaneously, the electrical connection between the regulating valves and the processing components further enhances the automation and intelligence of the device, thereby improving detection efficiency.

[0083] In some embodiments, as Figure 1 As shown, the openable cavity 120 includes two openable surfaces 1201, which are aligned in the conveying direction of the transmission assembly 111.

[0084] In this context, alignment refers to matching two or more components in relative positions to ensure they can work together correctly and effectively. In some embodiments, the conveying direction of the transmission assembly 111 can be... Figure 1 The X direction is shown.

[0085] The openable surface 1201 is a structure of the openable cavity 120 that enables it to be opened and closed. In some embodiments, the openable surface 1201 can be designed in various structural forms, including but not limited to translational, push-pull, folding, and lifting types.

[0086] In some embodiments, a seal is provided on the openable surface 1201, which is disposed at the lower end of the openable surface 1201 (i.e., near the end of the conveyor belt 1111) perpendicular to the conveying direction of the transmission assembly 111. This seal allows the conveyor belt 1111 to pass through the openable surface 1201 while simultaneously sealing the gap between the openable surface 1201 and the conveyor belt 1111. Exemplary seals may include sealing rubber strips, etc.

[0087] In some embodiments, one end of the seal can be fixedly connected to the lower end of the openable surface 1201 (e.g., by bonding), and the other end of the seal can be in direct contact with the conveyor belt 1111, so that the conveyor belt 1111 can pass through the openable surface 1201 and at the same time seal the gap between the openable surface 1201 and the conveyor belt 1111.

[0088] By setting a seal on the openable surface 1201, the sealing performance of the openable cavity 120 can be guaranteed as much as possible when the openable surface 1201 is closed, without affecting the conveyor belt 1111's transport of the product 200 to be tested, thereby ensuring the smooth conduct of waterproof and sealing performance testing.

[0089] In some embodiments, the openable cavity 120 is provided with a sensor and an automatic door opener, and the sensor is electrically connected to the automatic door opener.

[0090] A sensor is a sensing device or apparatus used to detect whether the product under test 200 is close to the openable surface 1201. For example, a sensor may include an infrared sensor, a microwave radar sensor, etc.

[0091] In some embodiments, the sensor can determine whether the product under test 200 is close to the openable surface 1201 by emitting and receiving infrared light. As an example only, the sensor is an infrared sensor. When the infrared sensor receives the infrared light emitted back by the product under test 200, it can be determined that the product under test 200 is close to the openable surface 1201.

[0092] In some embodiments, when the sensor detects that the product under test 200 is close to the openable surface 1201, it can send a signal to the automatic door opener to open the openable surface 1201. It should be noted that the sensor can be set at any feasible position on the openable cavity 120, as long as it can detect whether the product under test 200 is close to the openable surface 1201.

[0093] An automatic door opener is a device or apparatus capable of automatically opening and closing a door. In some embodiments, an automatic door opener can be used to control the opening or closing of the closable surface 1201.

[0094] In some embodiments, the automatic door opener may be of different types or categories depending on the structural form of the openable surface 1201. For example, when the structure of the openable surface 1201 is a sliding type, the automatic door opener may be a slide rail type. As another example, when the structure of the openable surface 1201 is a lifting type, the automatic door opener may be a sprocket and chain type.

[0095] In some embodiments, an automatic door opener can be mounted on the openable cavity 120 to control the opening or closing of the openable surface 1201. As an example only, when the openable surface 1201 has a lifting structure, the automatic door opener is a chain-type automatic door opener. The sprocket-chain type automatic door opener includes a door controller, a slide rail, at least two sprockets, at least two chains, and a motor. The motor is mounted on the openable cavity 120 corresponding to the upper end of the openable surface 1201. The motor's output shaft is connected to the sprockets. One end of the chain is wound around the sprocket, and the other end extends into the slide rail and is fixedly connected to one side of the openable surface 1201. The slide rail is mounted on the openable cavities 120 corresponding to both sides of the openable surface 1201. When the door controller receives a signal from the sensor, it can control the motor to rotate forward or backward, thereby driving the sprockets to rotate and controlling the chains to raise or lower the openable surface 1201. Understandably, the automatic door opener may also include a position feedback component to detect whether the openable surface 1201 has moved to a preset position.

[0096] It is worth noting that a sealing element may be provided at the connection between the openable cavity 120 and the openable surface 1201 to further ensure the sealing of the openable cavity 120 when the openable surface 1201 is closed.

[0097] In some embodiments of this specification, by setting sensors and automatic door openers on the openable cavity, the openable surface can be automatically opened when the product under test approaches it. This not only enables batch testing or measurement of the product under test in an assembly line manner, but also helps to further improve the automation and intelligence of the device, thereby further improving testing efficiency.

[0098] In some embodiments, the openable cavity 120 is provided with a spray assembly (not shown) and a drying assembly (not shown).

[0099] A spray assembly refers to a device or apparatus for spraying a test product 200 within an openable cavity 120. In some embodiments, the spray assembly includes a nozzle, a reservoir, and a control valve, with the nozzle and reservoir connected by a pipe.

[0100] The reservoir refers to a container used to store the spray liquid. In some embodiments, the reservoir may be located outside the openable cavity 120 (such as the outer side of the upper end face) to facilitate timely replenishment of the spray liquid by inspection personnel.

[0101] The nozzle can be used to spray the test product 200 within the openable cavity 120. In some embodiments, there can be one or more nozzles, and multiple nozzles can be distributed at multiple feasible locations within the openable cavity 120 to allow multiple test products 200 within the openable cavity 120 to be sprayed. Understandably, a seal (such as a sealing ring) can be provided at the connection point between the conduit and the openable cavity 120 to further ensure the airtightness of the openable cavity 120.

[0102] A control valve is installed on the pipeline to control the connection between the nozzle and the reservoir and to control the spray rate of the nozzle. In some embodiments, the control valve may be a solenoid valve. In some embodiments, the control valve is electrically connected to the processing assembly.

[0103] In some embodiments, the processing component can, in response to the driver pausing operation, control the control valve to open so that the nozzle sprays at a preset spray rate for a preset duration. The preset spray rate and preset spray time can be pre-set by the testing personnel based on historical data, past experience, etc. It should be noted that, in this embodiment, the processing component can, after spraying has finished, control the air pressure control component 122 to evacuate the openable cavity 120.

[0104] A drying assembly refers to a device or apparatus used to dry the product 200 to be tested within the openable cavity 120 after measurement. In some embodiments, the drying assembly includes a fan, a heating element, and a temperature control device, all of which are electrically connected to the processing assembly.

[0105] The fan is used to accelerate the airflow within the openable cavity 120. The heating element is used to heat the air within the openable cavity 120. The temperature control device is used to detect the air temperature within the openable cavity 120.

[0106] In some embodiments, the number of fans, heating elements, and temperature control devices can be one or more, and multiple fans, heating elements, and temperature control devices can be respectively arranged at any feasible position within the openable cavity 120. Taking the fans as an example, the number of fans is four, and the four fans can be evenly distributed on the upper surface of the openable cavity 120.

[0107] In some embodiments, the processing component can respond to the visual recognition component 121 completing the acquisition of a secondary image of the product under test 200, and control the heating element to operate at a preset heating power until the temperature reaches the preset temperature and then stops working. Simultaneously, the processing component will synchronously control the fan to start and operate at a preset speed. During this process, the temperature control component can monitor the air temperature inside the openable cavity 120 in real time to ensure that the air temperature inside the openable cavity 120 reaches the preset temperature. The preset heating power, preset temperature, and preset speed can all be set in advance by the testing personnel.

[0108] It should be noted that the drying unit can also be any other feasible equipment or device. For example, the drying unit may only include a fan, etc.

[0109] In some embodiments, the outer surface of the drying assembly may be covered with a waterproof coating to extend its service life. Exemplary waterproof coatings include, but are not limited to, polyurethane coatings.

[0110] In some embodiments of this specification, a spray assembly is used to spray the product under test, allowing for further determination of the product's waterproofness and airtightness by observing or comparing changes in the water droplets on the product's surface before and after measurement. Furthermore, by incorporating a drying assembly, the product under test can be dried promptly after measurement, minimizing the likelihood of water stains remaining.

[0111] In some embodiments, the processing component can be used to determine the waterproofness and airtightness of the product under test based on an initial image and a secondary image of the product under test. For example, the processing component can determine the waterproofness and airtightness of the product under test by means of image comparison or other methods based on the initial image and the secondary image. For instance, if the degree of contour deformation of the product under test in the secondary image and the initial image is small, or if the volume change of water droplets on the surface of the product under test is small, then the waterproofness and airtightness of the product under test are poor.

[0112] In some embodiments, the processing component can determine the waterproofness and airtightness of the product under test based on an initial image and a secondary image of the product under test using an image recognition model. The image recognition model can be a machine learning model. For example, the machine learning model can include one or more combinations of Deep Neural Network (DNN), Convolutional Neural Network (CNN), and similar models.

[0113] In some embodiments, the input to the image recognition model may include an initial image and a secondary image of the product under test, and the output of the image recognition model may be the waterproofness and airtightness of each product under test.

[0114] In some embodiments, the image recognition model can be trained based on a large number of labeled samples. For example, multiple labeled samples can be input into an initial image recognition model, and a loss function can be constructed using the labels and the output of the initial image recognition model. Based on the loss function, the parameters of the initial image recognition model are iteratively updated using gradient descent or other methods. When preset conditions are met, the image recognition model training is complete, and a trained image recognition model is obtained. These preset conditions may include loss function convergence, the number of iterations reaching a threshold, etc.

[0115] In some embodiments, the sample consists of an initial image and a secondary image of the product to be tested, and the label represents the actual waterproofness and actual airtightness of each product to be tested corresponding to the sample. The sample can be obtained based on historical data, and the label can be determined by manual annotation or other methods.

[0116] Some embodiments in this specification, through a well-trained image recognition model, can obtain more accurate judgment results, thereby improving the detection accuracy of the device.

[0117] The basic concepts have been described above. Obviously, for those skilled in the art, the detailed disclosure above is merely illustrative and does not constitute a limitation of this specification. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and corrections to this specification. Such modifications, improvements, and corrections are suggested in this specification and therefore remain within the spirit and scope of the exemplary embodiments described herein.
