[0036] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0037] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] In related technologies, the roller surface is usually cleaned by manually wiping it after the machine is stopped. However, the roller surface is relatively wide, and the residue becomes slightly sticky after cooling. The manual cleaning process takes more than 30 minutes, which is inefficient.

[0042] In addition, some diaphragm manufacturing processes require heating the roller surface. Before manual cleaning, the machine must be stopped to cool down, and care must be taken to avoid burns from the high temperature of the roller surface and residual heat from the equipment environment. Manual cleaning cannot be performed at regular intervals during normal equipment operation, often leading to the accumulation of oily substances, further increasing the difficulty of shutdown cleaning and prolonging the cleaning time.

[0043] In response to the above problems, such as Figure 1 As shown, an embodiment of this application provides a roller surface cleaning mechanism 100, mainly used for automatically cleaning the surface of a roller 200 in online or offline states. The roller surface cleaning mechanism 100 includes a vision detection component (not shown), a drive component 120, and a cleaning component 130.

[0044] The vision inspection component is used to detect whether there is dirt on the surface of the roller 200. The drive component 120 includes a drive component, and the vision inspection component is electrically connected to the drive component.

[0045] The visual inspection component includes a camera 111 and a control module (not shown). The camera 111 is used to take pictures of the surface of the roller 200, and the control module is used to analyze whether there are dirt in the pictures and the size of the dirt.

[0046] For example, when the control module analyzes that the dirt in the photo exceeds a certain size, it sends a control signal to the drive component 120, which then drives the cleaning component 130 to work.

[0047] For example, when the control module analyzes that the dirt in the photo does not exceed a certain size, it sends a control signal to the drive component 120, which then drives the cleaning component 130 to work and reset.

[0048] Camera 111 can be an industrial camera 111 or a CCD (Charge-Coupled Device) camera 111.

[0049] In this embodiment, as Figure 1 As shown, there are two cameras 111, each fixed to the frame, with the camera lens of each camera 111 facing the roller. The two cameras 111 are spaced apart along the axial direction of the roller 200. In other embodiments, the number of cameras 111 can be set as needed.

[0050] It should be noted that the frame 400 is set in the tank 500, located on the side of the roller 200 away from the diaphragm 300. In this application, the camera 111, drive assembly 120 and cleaning assembly 130 are fixed to the frame respectively, which improves the utilization rate of the frame 400, eliminates the need for additional fixed structures, and reduces costs.

[0051] It should be understood that the position of the roller 200 usually does not move during the production process of the diaphragm 300. Therefore, when installing the camera 111, the focusing operation of the camera 111 can be performed. After finding the best shooting position, the camera 111 is fixed and there is no need to move the camera 111 for focusing afterward.

[0052] In this embodiment, the driving components include a servo motor 121 and an integrated circuit cabinet (not shown).

[0053] The integrated circuit cabinet houses a PLC (Programmable Logic Controller) system, a touchscreen, analog input modules, and a pressure amplifier. The control module, which is electrically connected to camera 111, is also integrated into the integrated circuit cabinet.

[0054] The touch screen, analog input module, pressure amplifier, and control module are electrically connected to the PLC system.

[0055] The PLC system controls the start and stop of the servo motor 121 based on feedback information from the control module and the pressure amplifier.

[0056] The cleaning component 130 includes a connecting rod 131, which is arranged parallel to the roller 200. The servo motor 121 of the drive component 120 drives the connecting rod 131 to move closer to or away from the roller 200. The connecting rod 131 is used to clean dirt from the surface of the roller 200.

[0057] In this embodiment, since the connecting rod 131 can clean the surface of the roller 200 while it is online, the connecting rod 131 does not rotate while the roller 200 rotates, thereby achieving automatic cleaning of the surface of the roller 200, improving cleaning efficiency and cleaning effect.

[0058] In some embodiments, the drive assembly 120 further includes a clamping member 122, which includes a first connecting block 1221 and a second connecting block 1222.

[0059] like Figure 1 and Figure 2As shown, the first connecting block 1221 is connected to the output end of the drive component, and the second connecting block 1222 extends along the axial direction of the roller 200. The second connecting block 1222 connects the connecting rod 131 and the first connecting block 1221. Typically, the length of the connecting rod 131 is close to that of the roller 200, while the drive component is fixed on both sides of the roller 200. By setting the second connecting block 1222 to be elongated, the distance between the drive component and the roller 200 is changed, making the installation position of the drive component more flexible, and the output end of the drive component drives the connecting rod 131 to move.

[0060] In some embodiments, such as Figure 3 As shown, the first connecting block 1221 has a through hole 12211, the communication direction of which is parallel to the axial direction of the roller 200. One end of the second connecting block 1222 passes through the through hole 12211, and the other end is connected to the cleaning assembly 130. The first connecting block 1221 also has an opening 12212, which communicates with the through hole 12211. The opening 12212 is located on the side of the first connecting block 1221 away from the driving component. This facilitates the quick docking and installation of the first connecting block 1221 and the second connecting block 1222.

[0061] In some embodiments, a stacking hole is provided at the connection between the first connecting block 1221 and the second connecting block 1222. The communication direction of the stacking hole is perpendicular to the axial direction of the roller 200. The clamping member 122 also includes a fastening block 1223, which passes through the stacking hole and connects the first connecting block 1221 and the second connecting block 1222.

[0062] like Figure 3 As shown, in this embodiment, the overlapping hole is a threaded hole, and the fastening block 1223 is a screw, thereby tightening and fixing the first connecting block 1221 and the second connecting block 1222. In other embodiments, the overlapping hole can be a smooth hole, and the screw can be replaced with a pin.

[0063] There are two overlapping holes and two fastening blocks 1223. The two overlapping holes extend perpendicularly to the axial direction of the roller 200, and the two overlapping holes are spaced apart. In this way, the position of the connecting rod 131 can be adjusted by adjusting the second connecting block 1222.

[0064] In this embodiment, there are two drive components 120, which are spaced apart along the axial direction of the roller 200, so that the servo motor 121 operates smoothly and steadily. The up and down stroke of the connecting rod 131 is controlled by the servo motor 121 with high precision.

[0065] In some embodiments, such as Figure 4 As shown, the connecting rod 131 includes a first roller body 1311 and a second roller body 1312.

[0066] For example, both the first roller 1311 and the second roller 1312 are made of steel. The first roller 1311 and the second roller 1312 are integrally formed.

[0067] For example, the first roller 1311 is made of steel, and the second roller 1312 is made of high-temperature resistant plastic. This creates a flexible contact between the second roller 1312 and the roller 200, reducing surface deformation of the roller 200.

[0068] The first roller body 1311 is connected to the second connecting block 1222, making the connection more secure.

[0069] The second roller 1312 is connected to the side of the first roller 1311 near the roller 200. The side of the second roller 1312 facing the roller 200 is curved, which avoids the sharp corners of the second tube surface from scratching the surface of the roller 200.

[0070] In some embodiments, such as Figure 4 As shown, the first roller body 1311 has a plurality of slots 13111 formed on the side away from the roller 200. The cleaning assembly 130 also includes a plurality of fasteners 132, and each fastener 132 is removably disposed in a slot 13111.

[0071] For example, multiple slots 13111 are arranged in two rows along the axial direction of the connecting rod 131, and each row is provided with multiple slots 13111 spaced apart.

[0072] The fastener 132 is block-shaped; for example, the fastener 132 is a magnetic block made of permanent magnet. The shape of the slot 13111 matches the shape of the fastener 132.

[0073] In some embodiments, the cleaning assembly 130 further includes a cleaning cloth (not shown) that covers the side of the second roller 1312 near the roller 200, and the fastener 132 holds a portion of the cleaning cloth in the slot 13111.

[0074] In this way, the two sides of the cleaning cloth are secured into the slots 13111 by the fasteners 132. When the cleaning cloth needs to be replaced, the fasteners are removed from the slots 13111 to remove the cleaning cloth.

[0075] It should be noted that, in some embodiments, since the first roller body 1311 and the second roller body 1312 are separately arranged, the first roller body 1311 and the second roller body 1312 can be engaged, the middle part of the cleaning cloth covers the side of the second roller body 1312 near the roller 200, and the end of the cleaning cloth is engaged and fixed by the first roller body 1311 and the second roller body 1312, which simplifies the structure of the cleaning assembly 130.

[0076] In some embodiments, such as Figure 4As shown, the cleaning assembly 130 also includes at least one sensor 133, which is electrically connected to the drive component. The sensor 133 is located on the side of the connecting rod 131 near the roller 200 and is used to detect the pressure of the connecting rod 131 against the roller surface when it approaches the roller.

[0077] Sensor 133 is electrically connected to pressure amplifier. During the process of connecting rod 131 moving towards roller 200, after the surface of connecting rod 131 contacts the roller surface of roller 200, sensor 133 starts to detect the contact pressure and transmits the data to pressure amplifier in real time.

[0078] When the sensor 133 on the connecting rod 131 presses down to the set pressure, the servo motor 121 stops running, the connecting rod 131 begins cleaning, and when the camera 111 detects no dirt, the servo cylinder rises and returns to the initial position.

[0079] Please refer to the following: Figure 1 and Figure 2 In this application embodiment, a diaphragm 300 production apparatus is also provided, including a tank 500, a roller assembly (not shown) and a plurality of roller surface cleaning mechanisms 100 as described in any of the above embodiments.

[0080] like Figure 2 As shown, multiple roller assemblies are housed within a trough 500. The multiple roller assemblies are spaced apart along the height of the trough 500, and each roller assembly includes multiple rollers 200 spaced apart along the horizontal direction.

[0081] The diaphragm 300 is slidably connected to the surface of the roller 200. The rotation of the roller 200 drives the diaphragm 300 to move. The roller surface cleaning mechanism 100 is located on the side of the roller 200 away from the diaphragm 300.

[0082] Thus, during the production of diaphragm 300, when camera 111 captures images of dirt on the surface of roller 200, and the control module analyzes that the dirt in the image exceeds a certain size, servo motor 121 can drive connecting rod 131 to move to a position where roller 200 is not in contact with diaphragm 300, thereby achieving the purpose of cleaning the surface of roller 200 during the production of diaphragm 300.

[0083] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0084] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
