Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a cleaning device. Background Technology

[0002] With the development of the 3C industry, products with ordinary shapes can no longer meet market demands. For example, complex curved products (such as automotive glass) vary in length and size, and their production generally requires processes such as coating and lamination. Before coating and lamination, the product surface needs to be cleaned. Traditional cleaning machines generally include a housing, nozzles on the upper and lower sides of the spray unit in the housing, and air knives on the upper and lower sides of the drying unit in the housing. The nozzles and air knives of traditional cleaning machines are directly fixed to the housing via connecting rods or keels.

[0003] Traditional cleaning machines have limited compatibility and require different machines to be designed for products with different curvature ranges. Therefore, multiple cleaning machines are needed to meet the needs of different products. Utility Model Content

[0005] This application provides a cleaning device, comprising:

[0017] Furthermore, the transmission mechanism includes a transmission belt assembly, and the support surface of the transmission belt assembly is provided with support lines.

[0018] Furthermore, the support line is arranged in multiple intervals.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] The cleaning equipment provided in this application uses a lifting mechanism to adjust the height of the parallel cleaning mechanisms located on one side of the transmission mechanism, thereby adjusting the distance between the cleaning mechanism and the part to be cleaned. This allows the cleaning mechanism to adapt to changes in the shape of the part to be cleaned, ensuring that the spraying or blowing surface of the cleaning mechanism is consistent with the shape of the part to be cleaned. As a result, the surface of the part to be cleaned can be completely cleaned (cleaned with detergent, water or a mixture and dried) without the need to adjust the cleaning mechanism in the transmission direction. This solves the problem of limited compatibility of traditional cleaning machines, which require the design of different cleaning machines for products with different curvature ranges.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0041] See Figures 1 to 3 As shown in the figure, the cleaning equipment provided in this application embodiment can be used to clean the surface of the part 7 to be cleaned, wherein the part 7 to be cleaned can be glass, ceramic, sapphire, etc. This application does not limit the application scenario of the cleaning equipment. This application embodiment only takes the cleaning of the surface of irregular curved glass as an example for illustration.

[0042] Specifically, the cleaning equipment includes a housing 1 and a conveying mechanism 2. The housing 1 provides space for glass cleaning, such as... Figure 1As shown, the interior of the housing 1 is divided into multiple functional areas, mainly including a spray cleaning area 11 and a drying cleaning area 12. The spray cleaning area 11 is further divided into multiple functional zones, which are generally cleaned by spraying detergent, water or a mixture of solutions through nozzles. Cleaning is carried out step by step according to different functional zones. The drying cleaning area 12 mainly uses air knives to blow and dry the surface of the glass.

[0043] The conveying mechanism 2 is used to convey glass and includes a power unit 22 and a conveyor belt assembly 21. The conveyor belt assembly 21 includes at least two parallel conveyor belts. The number of conveyor belts can be set to 3, 4, 5 or more depending on the size of the glass; there is no limit to the number, as long as the conveying requirements are met. The conveyor belt assembly 21 extends from the inlet end of the housing 1 to the outlet end of the housing 1, running through the entire equipment.

[0044] The cleaning equipment provided in this application includes a cleaning mechanism 3 and a lifting mechanism 4. The cleaning mechanism 3 extends along the transmission direction of the transmission mechanism 2 and is located on at least one side of the transmission mechanism 2. There are at least two cleaning mechanisms 3 located on one side of the transmission mechanism 2, which are arranged parallel to each other. The lifting mechanism 4 is connected to the cleaning mechanism 3. With this configuration, the height of the parallel cleaning mechanisms 3 located on one side of the transmission mechanism can be adjusted by the lifting mechanism 4, thereby adjusting the distance between the cleaning mechanism 3 and different surface areas of the workpiece 7 to be cleaned. This allows the cleaning mechanism 3 to adapt to the shape changes of the workpiece 7 to be cleaned, ensuring that the spray or blowing surface of the cleaning mechanism 3 is consistent with the shape of the workpiece 7 to be cleaned. As a result, the surface of the workpiece 7 can be completely cleaned (cleaned with detergent, water or mixed liquid and dried) without adjusting the cleaning mechanism 3 in the transmission direction. This solves the problem of low compatibility of traditional cleaning machines, which require the design of different cleaning machines for products with different curvature ranges.

[0045] It should be noted that the cleaning mechanism 3 is set on one or both sides of the conveyor belt mechanism 2. For the part 7 to be cleaned that only needs to be cleaned on one side (for example, when the part 7 needs to be coated on one side, the surface to be coated needs to be cleaned), the cleaning mechanism 3 can be set on only one side. For the part 7 to be cleaned that needs to be cleaned on both sides, it can be set on both sides (upper and lower sides) of the conveyor mechanism 2 to achieve simultaneous cleaning of both sides of the part 7.

[0046] The number of cleaning mechanisms 3 located on one side of the surface to be cleaned is at least two and they are arranged in parallel to each other to accommodate the cleaning of parts of different shapes.

[0047] like Figure 7As shown, the cleaning mechanism 3 includes a nozzle assembly 31, an air knife assembly 32, and a keel 34. The nozzle assembly 31 and the air knife assembly 32 are respectively connected to the keel 34, which extends along the transmission direction of the transmission mechanism 2. The lifting mechanism 4 is connected to the keel 34 in a one-to-one correspondence.

[0048] In this embodiment of the application, the lifting mechanism 4 of the cleaning equipment is connected at one end to the housing 1 and at the other end to the keel 34 of the cleaning mechanism 3. By adjusting the keel 34 through the lifting mechanism 4, the distance between all the nozzle assemblies 31 and the air knife assemblies 32 on the keel 34 and different curved surfaces can be adjusted as a whole.

[0049] The cleaning mechanism 3 incorporates a keel 34 to prevent direct connection between the lifting mechanism 4 and the nozzle assembly 31 (for cleaning) and the air knife assembly 32 (for drying). This reduces the number of lifting mechanisms 4 and improves the efficiency of adjusting the nozzle assembly 31 and air knife assembly 32 in the same row along the transmission direction. Furthermore, by connecting the lifting mechanism 4 to the keel 34 in a one-to-one correspondence, each keel 34 can be adjusted to move independently, creating distances suitable for different curved surfaces, thus accommodating products with varying curvatures. To clean the glass surface, it requires cleaning with detergent, water, or a mixture followed by drying. Therefore, the cleaning mechanism 3 includes a nozzle assembly 31 and an air knife assembly 32. The nozzle assembly 31 sprays detergent, water, or a mixture onto the glass surface, while the air knife assembly 32 sweeps the glass surface with air. To improve cleaning efficiency, the nozzle assembly 31 is positioned within the spray cleaning zone 11, and the air knife assembly 32 can be positioned within both the spray cleaning zone 11 and the drying cleaning zone 12. For example, the spray cleaning zone 11 is provided with a plurality of nozzle assemblies 31 and a plurality of air knife assemblies 32, and the drying cleaning zone 12 is provided with a plurality of air knife assemblies 32.

[0050] like Figure 1 As shown, the curved glass flows from the feed end through the chemical spray section to remove dirt and impurities from the glass surface, then flows into the clean water spray section to rinse the glass clean, then passes through the air knife to dry it, and finally flows to the discharge end.

[0051] In a specific embodiment of this application, the nozzle assembly 31 is arranged in the same row area perpendicular to the transmission direction of the transmission mechanism 2, and the air knife assembly 32 is arranged in the same row area perpendicular to the transmission direction of the transmission mechanism 2. This avoids the situation where cleaning and drying occur simultaneously in the same row area perpendicular to the transmission direction of the transmission mechanism 2, which is beneficial to improving the cleaning and drying efficiency of the glass.

[0052] The nozzle assembly 31 includes a nozzle 311, and the air knife assembly 32 includes an air knife 321. Nozzles 311 in the same row perpendicular to the transmission direction of the transmission mechanism 2 can be connected using high-pressure sealed hoses 33 to allow the use of detergents with the same composition in the same cleaning area. Similarly, air knives 321 in the same row perpendicular to the transmission direction of the transmission mechanism 2 can also be connected using high-pressure sealed hoses 33.

[0053] When cleaning curved glass, the inconsistent height of the nozzle assembly 31 or air knife assembly 32 from the cleaning surface leads to inconsistent spray pressure or airflow intensity, resulting in uneven stress on the curved glass and thus ineffective cleaning. As a further improvement, the cleaning mechanism 3 is equipped with an adjustment mechanism 35. One end of the adjustment mechanism 35 is connected to the keel 34, and the other end is connected to the nozzle assembly 31 or air knife assembly 32. This allows for adjustment of the height of the nozzle assembly 31 and air knife assembly 32, making the distance between the end of the nozzle assembly 31 or air knife assembly 32 on the same side of the transmission mechanism 2 and the glass adjustable. This allows for adaptive adjustment of the distance between the nozzle assembly 31 and air knife assembly 32 and the glass according to the glass shape, further improving cleaning efficiency.

[0054] As a further improvement, a slide rail is provided on the keel 34, and one end of the adjustment mechanism 35 is movably disposed within the slide rail. Since the slide rail extends along the transmission direction of the transmission mechanism 2, and the nozzle assembly 31 and the air knife assembly 32 are connected to the adjustment mechanism 35, the positions of the nozzle assembly 31 and the air knife assembly 32 on the keel 34 can be adjusted by moving the adjustment mechanism 35 on the slide rail, ensuring that the nozzle assembly 31 is disposed in the same row area perpendicular to the transmission direction of the transmission mechanism 2, and the air knife assembly 32 is disposed in the same row area perpendicular to the transmission direction of the transmission mechanism 2.

[0055] like Figure 3 The diagram shows the structure of the drying and cleaning zone 12, which has a fan 8 at the top and an air knife blowing zone at the bottom. Due to the curved surface of the glass, the air force blown by the air knife 321 onto the glass surface is at a certain angle (not vertical), which can lead to uneven force on the glass surface. To reduce this effect, the nozzle assembly 31 or the air knife assembly 32 is rotatably connected to the adjustment mechanism 35, so that the angle between the nozzle assembly 31 or the air knife assembly 32 and the glass surface is adjustable.

[0056] Specifically, the nozzle assembly 31 or the air knife assembly 32 is hinged to the end of the adjusting mechanism 5 away from the keel 34, and a locking mechanism is provided, such as a pin lock or a tooth lock. It should be noted that in this embodiment, the nozzle assembly 31 or the air knife assembly 32 and the adjusting mechanism 5 can be rotatably connected in a manner that includes, but is not limited to, hinged connection; it is sufficient to achieve rotation angle adjustment.

[0057] Figure 3The angle adjustment of the air knife assembly 32 is shown. Of course, the nozzle assembly 31 can also adopt the same adjustment method to achieve uniform force on the glass when spraying the cleaning liquid.

[0058] As a specific embodiment for achieving height adjustment of the keel 34, the lifting mechanism 4 includes a first connecting rod 41, one end of which is connected to the keel 34, and the other end is connected to the housing 1. The keel 34 can be connected to the housing 1 via the first connecting rod 41. The first connecting rod 41 adopts a telescopic structure; for example, it can be a multi-section telescopic rod structure, with each section locked together by an elastic locking pin. Alternatively, the telescopic mechanism of the first connecting rod 41 can also be a multi-section threaded telescopic mechanism, where height adjustment is achieved by rotating the thread.

[0059] In a further embodiment, the first connecting rod 41 is provided with a plurality of first connecting structures 411 in its length direction. For example, the first connecting structure 411 can be a locking pin hole. The keel 34 can be locked and connected by a pin. The keel 34 can selectively use one of the first connecting structures 411 to connect with the first connecting rod 41. When the height needs to be adjusted, it can be connected by switching to another locking pin hole to realize the height adjustment of the keel 34.

[0060] The multiple first connection structures 411 can be continuous connection points, such as when adjusting the height using threads, or they can be multiple spaced points, such as when connecting with multiple pin holes.

[0061] Of course, the multiple first connection structures 411 can also be formed by multiple elastic snap-fit ​​points, and their connection method is similar to that of pin connection.

[0062] In a further embodiment, the height of the keel 34 can be automatically adjusted via a drive mechanism, which can be a servo motor, cylinder, or similar structure. The type of drive mechanism is not limited, as long as it meets the requirements for automated control.

[0063] As a specific implementation method to achieve height adjustment of the nozzle assembly 31 or the air knife assembly 32, such as Figures 2 to 3 As shown, the adjustment mechanism 35 includes a second connecting rod 351. The nozzle assembly 31 and the air knife assembly 32 are respectively connected to the keel 34 via the second connecting rod 351, so as to adjust the height of the nozzle assembly 31 and the air knife assembly 32 via the second connecting rod 351.

[0064] In a further embodiment, such as Figure 2 , 3 as well as Figure 5As shown, the second connecting rod 351 is also a telescopic structure (such as a telescopic rod), and the nozzle assembly 31 and the air knife assembly 32 are height-adjusted by the extension and retraction of the second connecting rod 351. The telescopic structure of the second connecting rod 351 can also be similar to the telescopic structure of the first connecting rod 41, and can adopt a multi-section telescopic method.

[0065] Similarly, the second connecting rod 351 may also be provided with multiple second connecting structures 3511 in its extension direction. The nozzle assembly 31 or the air knife assembly 32 may be selectively connected to one of the multiple second connecting structures 3511 to achieve height adjustment of the nozzle assembly 31 or the air knife assembly 32.

[0066] Similarly, the height of the nozzle assembly 31 or the air knife assembly 32 can be automatically adjusted through the drive mechanism.

[0067] As a further improvement, the lifting mechanism 4 is provided with a height indicating structure. Exemplarily, the height indicating structure is a first scale 412. (See reference...) Figure 4 The first connecting rod 41 is provided with a first scale 412 in the area where multiple first connecting structures 411 are provided. The height of each keel 34 can be intuitively understood through the first scale 412, so as to realize the data-driven height adjustment of the cleaning component 3.

[0068] As a further improvement, the adjustment mechanism 35 also includes a height indication structure. Exemplarily, the height indication structure is a second scale 3512. (See reference...) Figure 5 The area where the second connecting rod 351 is provided with multiple second connecting structures 3511 is provided with a second scale 3512 to realize the height adjustment data of the nozzle assembly 31 or the air knife assembly 32, so as to more accurately adjust the relative extension length of the air knife 321 or the nozzle 311, and at the same time avoid the nozzle / air knife from scratching the glass during the glass operation.

[0069] For example, when processing curved glass A, the water spraying distance needs to be 10cm and the air drying distance needs to be 6cm. First, the height of the nozzle assembly 31 and the air knife assembly 32 on the single keel 34 is adjusted by the adjustment mechanism 35 so that the nozzle 311 is 4cm longer than the air knife 321. Then, they are installed on the same keel 34 respectively, and the height of the single keel 34 is adjusted according to the curvature of the glass. Then, by adjusting the different combinations of parallel keels 34 up and down, the distance is adapted to different curvatures, thereby adapting to products with different curvatures.

[0070] As a further improvement, the cleaning equipment in this embodiment is also provided with a moving mechanism, which is horizontally arranged on the housing 1. The lifting mechanism 4 is connected to the moving mechanism. With this arrangement, the lifting mechanism 4 can move on the housing 1 through the moving mechanism, and its moving direction is perpendicular to the transmission direction of the transmission mechanism 2, so that the spacing between the keels 34 can be adjusted according to the different glass sizes.

[0071] Specifically, the moving mechanism can be a linear sliding module that is perpendicular to the transmission direction of the transmission mechanism 2. The lifting mechanism 4 is connected to the linear sliding module, so that the lifting mechanism 4 and the keel 34 can move in a direction perpendicular to the transmission direction of the transmission mechanism 2 by sliding the lifting mechanism 4 linearly on the linear sliding module.

[0072] In this embodiment, the transmission mechanism 2 includes a transmission belt assembly 21. The glass transmission process is mainly realized through the transmission belt assembly 21. It is worth noting that there is a contact surface between the transmission belt assembly 21 and the glass, which makes it impossible to effectively clean the contact surface. In order to reduce the contact area between the transmission belt assembly 21 and the glass and improve the cleaning effect, a support line 211 is provided on the support surface of the transmission belt assembly 21. During the glass transmission process, the glass contacts the support line 211, thereby reducing the contact area.

[0073] To further improve the cleaning effect and reduce the contact area, the support line 211 has a multi-segment, shorter structure and is spaced apart, which ensures the support effect while further reducing the contact area.

[0074] Furthermore, the support line 211 adopts a cylindrical structure to further reduce the contact area and improve the cleaning effect. In this embodiment, the support line 211 can be made of fishing line that is resistant to high temperature and cleaning agent corrosion.
