Description

Technical Field

[0001] The invention relates to the technical field of duster strength detection, in particular to a duster wear resistance and durability life test device. Background Art

[0002] Dust duster is a traditional cleaning tool, mainly used to remove dust from the surface of furniture, electrical appliances and other items. Dust duster usually consists of a long strip-shaped duster head and a handle. The duster head can be made of natural or synthetic materials, such as chicken feathers or microfibers, which can absorb dust and avoid dust during cleaning. Modern dust dusters often use electrostatic adsorption technology, which can quickly absorb tiny particles such as dust and hair, which is convenient and hygienic. The design of dust duster is also more humane, and some can be retracted and bent, which is convenient for cleaning high places and hard-to-reach corners. It is not only suitable for daily household cleaning, but also an indispensable tool in the custom of sweeping dust before the Spring Festival, symbolizing "removing the old and bringing in the new", and embodying people's desire to break the old and establish the new.

[0003] At present, the duster head on the dust duster is connected to the handle by rope, bonding, or a combination of the above two methods. When actually using it, people usually hold the handle to make the handle drive the duster head to swing left and right, move horizontally, or rotate, so that the duster head can come into contact with the surface of the wiped object, and the dust on the surface of the wiped object can be taken away by the duster head.

[0004] For any dust duster, as a mass-produced cleaning product, it is also necessary to provide the public with a reference value for its service life to ensure that the dust duster is durable. However, there is currently no formal equipment on the market for testing the service life of dust dusters.

Next, the operator inputs information through the information display module, which will be transmitted to the data processing module and the control module. The control module will control the rotating component, the swinging component or the translation component to pause after a preset number of times. During the pause, the cylinder will drive the test plate downward to enable the image acquisition module to capture the top surface image of the test plate. The data processing module then analyzes the top surface image to identify whether the duster has hair removal. If the duster does not remove hair, the cylinder will drive the test plate to rise and continue to perform the predetermined action for testing. On the contrary, if the duster removes hair, the cylinder will also drive the test plate to rise, but the rotation, swing and translation components will stop working at this time. The data processing module will record the number of turns of the rotation component, the number of reciprocating times of the swing component or the number of reciprocating times of the translation component at this time, and display these data together with the test results on the information display module for the operator to check; After the operator has read the information and removed the duster from the three-jaw chuck, they need to replace the new duster and re-enter the test information to complete the remaining test process. Each duster only completes one test on this device. Once the duster loses hair, the operator will manually replace the duster and the control module will switch to the next test. For example, if the first test uses the rotating component, the second test will use the rocking component or the translation component. The device can reduce the number of devices required for duster life test. In addition, when it is necessary to switch between the rotating component, the swing component and the translation component, the operator only needs to adjust the connection and disconnection state between them without the need for additional equipment. This integrated design not only saves space, but also simplifies the duster fixing process. Only one three-jaw chuck is needed to fix all test components without the need for additional clamping structure. Through this integrated and simplified design, the present invention not only improves the test efficiency, but also reduces the complexity of operation, making the service life test of the dust duster more convenient and, the device also provides an efficient and reliable testing solution for dust duster manufacturers and users, helping to ensure the quality and performance of dust duster products.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] A dust duster wear resistance and durability life test device, such as Figure 1 and Figure 4As shown, it includes a main frame 1, top side frames 2 fixedly connected to both sides of the top surface of the main frame 1, a test board 9, a rotating assembly, a swinging assembly, and a translation assembly 3. The translation assembly 3 is arranged between the top side frames 2 on both sides. A partition 24 located below the top side frame 2 is fixedly connected inside the main frame 1. The rotating assembly is used to clamp the handle of the dust duster and drive the dust duster to rotate. The movable end of the rotating assembly and the translation assembly 3 are detachably connected. The swinging assembly is arranged below the rotating assembly. The rotating assembly and the movable end of the swinging assembly are fixedly connected. The swinging assembly can be positioned at any position in the length direction of the partition 24. When the rotating assembly is connected to the movable end of the translation assembly 3 and the swinging assembly is not positioned on the partition 24, the rotating assembly can follow the movable end of the translation assembly 3 to move back and forth in the length direction of the partition 24. When the rotating assembly is disengaged from the translation assembly 3 and the swinging assembly is positioned on the partition 24, the rotating assembly can follow the movable end of the swinging assembly to swing back and forth horizontally. The test board 9 is arranged on the front of the main frame 1 and its height can be adjusted in the height direction of the main frame 1.

[0027] like Figure 6 As shown, it also includes an image acquisition module 26, a data processing module 27, a control module 28, and an information display module 25. The information display module 25 is fixedly connected to the top side frame 2. The information display module 25 is coupled to the data processing module 27. The output end of the image acquisition module 26 is coupled to the input end of the data processing module 27. The data processing module 27 is coupled to the control module 28. The image acquisition module 26 is arranged on the main frame 1. The image acquisition module 26 is used to acquire the top surface image of the test board 9 after downward displacement and feed it back to the data processing module 27. The data processing module 27 is used to identify the dust removal situation according to the top surface image of the test board 9 and collect information from the control module 28 and then transmit it to the information display module 25. The information display module 25 is used to display the information transmitted by the data processing module 27. The control module 28 is used to control the switching of the rotating component, the swinging component, and the translation component 3, the lifting of the test board 9 and feed back information to the data processing module 27. Among them, the image acquisition module 26 includes a camera, the data processing module 27 includes a processor, the control module 28 includes a controller, and the information display module 25 includes a touch panel.

[0028] When the duster needs to be tested for its service life, the operator only needs to manually insert the handle of the duster into the three-jaw chuck 14 and adjust the three-jaw chuck 14 until its clamping jaws stably clamp the handle of the duster. Then the operator can input information to the data processing module 27 and the control module 28 through the information display module 25, determine how many times the rotating component, the swing component, or the translation component 3 works and then stop working, and after the cylinder 7 moves downward when the work is stopped, the image acquisition module 26 acquires the top surface image of the test plate 9, and then the data processing module 27 identifies the content in the top surface image, and then identifies the dust duster hair loss situation, if the dust duster does not lose hair, the cylinder 7 drives the test plate 9 to rise again, and then controls the rotating component, the swing component, or the translation component to move downward, and then controls the rotating component, the swing component, or the translation component to move upward, and finally ... Component 3 continues to work, and if the duster sheds hair, the cylinder 7 drives the test plate 9 to rise again, but stops the work of the rotating component, the swing component, or the translation component 3, and the data processing module 27 collects the number of rotations of the rotating component, the number of reciprocating times of the swing component, or the number of reciprocating times of the translation component 3 in the control module 28 at this time, and transmits it to the information display module 25 for display in combination with the output result, and waits for the operator to read the information, remove the duster from the three-jaw chuck 14 and replace it with a new one, and then re-enter the information again to complete the remaining subsequent detection actions; Each duster only completes one of the tests on the device. When the duster sheds hair, the operator can manually replace the duster, and then the control module 28 switches to the other test. If the first test is performed by the rotating component, the second test is performed by the swing component or the translation component 3. The service life of the dust duster can be tested by the present device, so that people do not need to prepare multiple devices to test the dust duster, and when the rotating component, the swing component, or the translation component 3 of the present device is switched, it is only necessary to adjust the connection and disconnection states with each other, and the rotating component, the swing component, and the translation component 3 can be integrated together, so that the volume of the present device does not occupy a large space. At the same time, the integration of the rotating component, the swing component, and the translation component 3 also makes it possible to clamp and fix the dust duster with only a three-jaw chuck 14, without the need to add an additional clamping structure.

[0029] Preferably, connecting frames 6 are fixedly connected to both sides of the front of the main frame 1, a vertically arranged cylinder 7 is fixedly connected to the connecting frame 6, a movable end of the cylinder 7 is fixedly connected to a side frame 8, and a test plate 9 is fixedly connected between the side frames 8 on both sides.

[0030] By setting up the connecting frame 6, the connecting frame 6 can provide a supporting basis for the setting of the cylinder 7. The cylinder 7 can be connected to the air pump through the air pipe. The air pump can be coupled to the control module 28 so that the control module 28 can control the lifting of the cylinder 7. The setting of the cylinder 7 provides a basis for the lifting of the side frame 8 and the test plate 9, ensuring that the side frame 8 and the test plate 9 can be relatively stable when lifting.

[0031] Preferably, the translation assembly 3 includes a track fixedly connected between the top side frames 2 on both sides, a servo motor horizontally fixedly connected to the top side frame 2 on one side, a reciprocating screw rotatably connected in the track, a threaded sleeve threadedly connected to the reciprocating screw and slidably connected in the track, and a slide fixedly connected to the threaded sleeve, the output shaft of the servo motor passes through the track and is coaxially connected to one end of the reciprocating screw, and a groove located below the rotating assembly is provided on the top surface of the slide.

[0032] When the dust duster needs to perform horizontal displacement reciprocating detection, it is only necessary to fix the dust duster on the three-jaw chuck 14 of the rotating assembly, and then cut off the power to the traction electromagnet 5, so that the movable rod of the traction electromagnet 5 can be extended and displaced into the embedded groove of the slide. At this time, the movable rod of the traction electromagnet 5 completes the detachable connection between the turntable 4 and the slide, and the servo motor is coupled to the control module 28 to ensure that the control module 28 controls the servo motor to drive the reciprocating screw to rotate. When the reciprocating screw rotates, it tries to drive the threaded sleeve to rotate, but the threaded sleeve is restricted by the track, so it can only move back and forth along the length direction of the track. In the process, the slide is moved together, and the slide will drive the turntable 4, the rotating assembly, and the rocking assembly to move back and forth through the movable rod of the traction electromagnet 5. The dust duster fixed on the three-jaw chuck 14 in the rotating assembly can also contact and reciprocate with the top surface of the test plate 9, thereby completing the test.

[0033] Preferably, if Figure 2 As shown, the rotating assembly includes a turntable 4 located above the slide, a mounting seat 10 fixedly connected to the turntable 4, an inclined connecting seat 11 fixedly connected to the upper end of the mounting seat 10, and a horizontal connecting seat 12 fixedly connected to the inclined connecting seat 11 and horizontally arranged, the inclined connecting seat 11 is fixedly connected with a horizontal driving motor 15 located in the mounting seat 10, a bearing 13 is fixedly connected to the vertical end surface of the horizontal connecting seat 12, the inner ring of the bearing 13 is fixedly connected with a connecting shaft, one end of the connecting shaft is fixedly connected with a three-jaw chuck 14, and the other end of the connecting shaft passes through the vertical end surface of the horizontal connecting seat 12 to the inside thereof, the output shaft of the horizontal driving motor 15 is connected to the end of the connecting shaft located inside the horizontal connecting seat 12 through a universal coupling, the turntable 4 is fixedly connected with a traction electromagnet 5 arranged away from the three-jaw chuck 14, the traction electromagnet 5 can be set to be powered on and off, and the movable rod of the traction electromagnet 5 can pass through the turntable 4. When the rotating assembly is connected to the translation assembly 3, the movable rod of the traction electromagnet 5 is displaced into the embedded groove.

[0034] If the rotating assembly needs to perform rotation detection on the dust duster, at this time, the swing assembly and the translation assembly 3 do not need to work. It is only necessary to keep the handle of the dust duster fixed in the three-jaw chuck 14 in the rotating assembly, and the horizontal drive motor 15 remains coupled with the control module 28. The control module 28 drives the horizontal drive motor 15 to work. The output shaft of the horizontal drive motor 15 drives the connecting shaft to rotate in the bearing 13 through the universal coupling. When the connecting shaft rotates, it can drive the three-jaw chuck 14 and the dust duster fixed thereon to rotate, so that the dust duster contacts the top surface of the test plate 9 and continues to rotate, thereby completing the rotation detection action.

[0035] Preferably, the rocking assembly includes a mounting frame 16, a crank rocker structure arranged on the mounting frame 16, and an adsorption member arranged on the mounting frame 16 and having a bottom surface flush with the mounting frame 16. There is a gap between the mounting frame 16 and the top surface of the partition 24. The movable end of the rocker of the crank rocker structure is fixedly connected to the bottom surface of the turntable 4. The center of the movable end of the rocker of the crank rocker structure is coaxially arranged with the center of the turntable 4. When the rotating assembly is disengaged from the translation assembly 3 and the rocking assembly is positioned on the partition 24, the adsorption member is detachably connected to the partition 24, such as Figure 3 As shown, the partition 24 is a metal plate, and the adsorption member includes an electromagnet 23, which can be turned on and off, and the gap is 0.5-2mm. Figure 5 As shown, the crank rocker structure includes a rotating shaft 17 vertically rotatably connected to a mounting frame 16, a guide rod 18 fixedly connected to the upper end of the rotating shaft 17, a vertical drive motor 20 vertically fixedly connected in the mounting frame 16, a drive disk 21 coaxially fixedly connected to the output shaft of the vertical drive motor 20, and a guide shaft 22 eccentrically fixedly connected to the top surface of the drive disk 21, the guide rod 18 is fixedly connected to the bottom surface of the turntable 4, and the rotating shaft 17 is coaxially arranged with the turntable 4, the bottom surface of the guide rod 18 is provided with a guide groove 19 consistent with its length direction, the guide shaft 22 is cylindrical, and the upper end of the guide shaft 22 extends to the guide groove 19 to rotate and slide.

[0036] When the dust duster needs to perform swing detection, it is necessary to energize the traction electromagnet 5 so that the movable rod of the traction electromagnet 5 leaves the embedded groove, and the rotating component and the translation component 3 remain in a disengaged state. At this time, it is also necessary to energize the electromagnet 23 so that the mounting frame 16 can be firmly adsorbed on the metal partition 24 through magnetic force. The mounting frame 16 undergoes a certain degree of elastic deformation, and then adapts to the state of the electromagnet 23 being attracted to the partition 24, thereby ensuring that the mounting frame 16 will not deviate or move. The vertical drive motor 20 is coupled to the control module 28, so that the control module 28 can control the vertical drive motor 20 to work, and the vertical drive motor 20 can drive the drive disk 21 to move when working. The guide shaft 22 rotates around its central axis on the driving disk 21, and the guide shaft 22 extends to the guide groove 19 of the guide rod 18 to rotate and slide, so that the guide rod 18 will swing back and forth, and since the rotating shaft 17 is coaxially arranged with the turntable 4, the turntable 4 can swing back and forth about its center, and the mounting base 10, the inclined connecting base 11, the horizontal connecting base 12, and the three-jaw chuck 14 fixed on the turntable 4 can swing back and forth together. During this process, the handle of the dust duster remains fixed in the three-jaw chuck 14, so that the dust duster can contact the top surface of the test plate 9 and swing back and forth, thereby completing the swing test.

[0037] Preferably, the data processing module 27 is used to identify the duster hair loss situation according to the top surface image of the test board 9 and collect information from the control module 28 and transmit it to the information display module 25, including the following steps: Get the top surface image and convert it to the HSV color space to obtain the hue of each pixel in the top surface image , Saturation , and brightness ; Set threshold ranges for hue, saturation, and brightness of each pixel in the top image , and filter the soft fiber drop area in the top surface image by the threshold range to obtain a binary image , the binary image only retains the areas that meet the threshold range: ; Use erosion to remove small noise , where B is a structural element, usually a small rectangle or circle is selected, and the small white noise will be removed after the operation; Use edge detection algorithms to detect the outline of dropped objects ,in, and It is the low threshold and high threshold of the canny edge detection algorithm; Calculate the area of ​​the dropped object based on its extracted outline ,in, is the pixel point in the outline of the dropped object; Set the area threshold of the dropped object. If the outline area of ​​the dropped object is larger than the area threshold, the output result is that the duster has dropped hair. Otherwise, the output result is that the duster has not dropped hair. The number of rotations of the rotating component, the number of reciprocating times of the swing component, or the number of reciprocating times of the translation component 3 in the control module 28 is extracted and transmitted to the information display module 25 together with the output result.

[0038] Through the above method steps, the data processing module 27 can more accurately extract the duster-dropped objects with obvious color difference from the top surface image of the test board 9. Of course, this requires the operator to ensure that there is an obvious color difference between the color of the soft object on the duster and the color of the test board 9. If the color difference is small when judged by the naked eye, then stickers of different colors can be posted on the test board 9 to ensure that there is an obvious color difference between the test board 9 and the soft object on the duster. When a drop with obvious color difference is on the top surface of the test board 9, the top surface image will be converted into a color space in advance. The RGB color space is a color space of three primary colors, which mixes color information together, while the HSV color space separates the brightness, hue and saturation of the color, making the color feature more distinguishable. There may be significant differences in brightness or saturation between the dust duster drop and the pure color test board 9, and the HSV space provides a more intuitive way to separate these differences. At the same time, because the hue in the HSV space is less sensitive to brightness changes, this helps to deal with the impact caused by changes in lighting; Then, the threshold range is set. The threshold range is adjusted by the operator according to the color of the soft object of the duster. By filtering with the threshold range, only the areas that meet the specific color characteristics (for example, the color of the duster and the dropped object) are retained. The corrosion operation can be used to effectively remove background noise and reduce interference from other irrelevant areas. Then, the edge detection algorithm is used to determine the outline of the dropped object, and the outline area of ​​the dropped object is calculated, so as to determine that a large number of dropped objects have occurred rather than a small amount of hair loss, so that the output result of the final data processing module 27 is more accurate.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
