[0146] This invention discloses a cleaning system to reduce manual labor intensity and improve cleaning efficiency.

[0147] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0148] like Figure 1As shown, this embodiment of the invention provides a cleaning system, including a pallet loading module 1, a pallet unloading module 14, a transmission component 8, a product loading module 2, a product unloading module 13, and a cleaning component. The system includes: a pallet loading module 1 for conveying pallets carrying products to be cleaned; a pallet loading module 1 having a pallet input position and a first loading position; a pallet unloading module 14 for conveying pallets carrying cleaning products; a pallet unloading module 14 having a pallet output position and a first unloading position; a pallet unloading module 14 for conveying pallets from the first unloading position to the pallet output position; a transmission component 8 having a product input position and a product output position; a product loading module 2 for transferring products from the pallet at the first loading position to the product input position; a product unloading module 13 for transferring products from the product output position to the first unloading position; and a cleaning component located between the product input position and the product output position for cleaning the products transmitted on the transmission component 8. The cleaning component includes a first cleaning device and a second cleaning device, the first cleaning device for cleaning the protrusions of the product, and the second cleaning device for cleaning the large surface of the product.

[0149] The cleaning system provided in this embodiment of the invention involves placing the product to be cleaned on a tray. The tray is then transferred via a tray loading module 1. The tray is manually or using external equipment to place it at the tray input position of the tray loading module 1, which then transfers the tray from the input position to a first loading position. Next, a product loading module 2 transfers the product from the tray at the first loading position to a product input position, completing the transfer and loading of the product to be cleaned. Following this, a transfer component 8 transfers the product from the product input position to the product output position. During this transfer, a cleaning component is positioned between the product input and output positions to clean the product transferred by the transfer component 8. A first cleaning device cleans the protrusions of the product, and a second cleaning device cleans the large surfaces of the product. Finally, a product unloading module 13 transfers the cleaned product from the product output position to the tray at the first unloading position, and a tray unloading module 14 transfers the tray from the first unloading position to the tray output position. This configuration avoids manual wiping, effectively reducing labor intensity and improving cleaning efficiency.

[0150] The above settings effectively improve labor productivity, avoid harm to the human body caused by manual cleaning, and significantly increase cleaning efficiency and cleaning power.

[0151] In the cleaning system provided in this embodiment of the invention, the product is a plate-like structure with protrusions extending from the large surface (outer surface of the plate-like structure). For example, the product is a mobile phone glass back cover, and the protrusion is a raised ring corresponding to the mobile phone camera; or, the product is a camera housing, and the protrusion is a raised ring corresponding to the camera lens; or, the product is a detection device housing, and the protrusion is a detection port, etc.

[0152] The cleaning system provided in this embodiment of the invention integrates cleaning components, a tray loading module 1, and a tray unloading module 14. It can clean the products (glass) to be cleaned on the tray and place the cleaned products (glass) back onto the tray. This avoids direct contact with the products during loading and unloading, especially since the unloaded products are placed on the tray, preventing direct contact with hands or other equipment during transport, thus effectively improving the cleaning effect.

[0153] The cleaning system provided in this embodiment of the invention also includes an empty pallet transport component; such as Figure 1 and Figure 13 As shown, the empty pallet transfer assembly includes an empty pallet transfer module 15, a first empty pallet transfer module 16, and a second empty pallet transfer module 17. The empty pallet transfer module 15 has a pallet input station and a pallet output station, and can transfer empty pallets from the pallet input station to the pallet output station; the first empty pallet transfer module 16 can transfer empty pallets from the first loading station to the pallet input station; and the second empty pallet transfer module 17 can transfer empty pallets from the pallet output station to the first unloading station.

[0154] The above settings enable the transfer of empty pallets, allowing them to be reused, avoiding the need for separate handling of empty pallets, further saving labor and improving efficiency.

[0155] like Figure 12 and Figure 13 As shown, the first empty pallet transfer module 16 includes a pallet conveying device 16-2 and a pallet gripping device 16-1 capable of moving along the extension direction of the pallet conveying device 16-2. The pallet gripping device 16-1 is capable of gripping the top surface of the pallet. Through the above arrangement, the pallet gripped by the pallet gripping device 16-1 will not affect the structure below the pallet (such as other pallets).

[0156] Similarly, the second empty pallet transfer module 17 has the same structure as the first empty pallet transfer module 16.

[0157] To improve structural compactness and avoid interference between mechanisms during pallet transfer, the first empty pallet transfer module 16 and the second empty pallet transfer module 17 are positioned higher than the empty pallet transfer module 15.

[0158] The empty pallet transfer assembly also includes a first empty pallet lifting structure 18 and a second empty pallet lifting structure 19. The first empty pallet lifting structure 18 can lower the pallet gripped by the pallet gripping device 16-1 of the first empty pallet transfer module 16 to the pallet input station; the second empty pallet lifting structure 19 can raise and transfer the empty pallet from the pallet output station to the position where the pallet gripping device 16-1 of the second empty pallet transfer module 17 can grip it.

[0159] The above configuration allows the first empty pallet transfer module 16 and the second empty pallet transfer module 17 to overlap with the vertical projection of the empty pallet transfer module 15, effectively improving the overall structural compactness.

[0160] like Figure 14 As shown, the empty pallet transport module 15 further includes a manual receiving station located between the pallet input station and the pallet output station. The empty pallet transport assembly also includes a manual receiving device 20, which can transport empty pallets received at the manual receiving station to the outside of the empty pallet transport module 15. The transport direction of the manual receiving device 20 forms an angle with the transport direction of the empty pallet transport module 15. This configuration facilitates the recycling of empty pallets and also facilitates maintenance and repair operations on empty pallets within the pallet transport system formed by the cleaning system.

[0161] The cleaning system provided in this embodiment of the invention also includes a flipping component 3, which is used to flip the product being transported on the transmission component 8. By flipping the product using the flipping component 3, the transmission direction of the product on the transmission component 8 can be adjusted. Taking a back cover glass plate as an example, the product is placed on a tray with its inner side facing upwards. The robotic arm transfers the product from the tray to the flipping component 3, which flips the product 180° so that its inner side faces downwards on the transmission component 8, facilitating the cleaning component to wipe and clean the outer side of the product.

[0162] The flipping component 3 can be placed between the product input station and the cleaning component.

[0163] Of course, the flipping component 3 can also be placed between the cleaning component and the product output station.

[0164] like Figure 2As shown, the cleaning system provided in this embodiment of the invention includes a flipping assembly 3 comprising a lifting structure and a flipping structure. The lifting structure includes a flipping lifting component 3-1, a lifting base 3-2, and a lifting drive device 3-3. The lifting drive device 3-3 can drive the flipping lifting component 3-1 to rise and fall relative to the lifting base 3-2, and the lifting base 3-2 is fixed relative to the transmission assembly 8. The flipping structure includes a flipping plate 3-4 and a flipping drive device 3-6. The flipping plate 3-4 is rotatably connected to the flipping lifting component 3-1, and the flipping drive device 3-6 can drive the flipping plate 3-4 to switch between a first state and a second state.

[0165] In the first state, the first side of the flip plate 3-4 is set facing upwards and is used to grip the product; in the second state, the first side of the flip plate 3-4 is set facing downwards.

[0166] By combining the lifting structure and the flipping structure, the horizontal height of the product after flipping can be controlled to facilitate subsequent transfer operations on the transfer component 8. For example, if the height of the component carrying the product on the subsequent transfer component 8 is constant, the lifting structure, in conjunction with the flipping structure, allows the product to be flipped so that it matches the component carrying the product on the transfer component 8.

[0167] Of course, the flipping component 3 can also be made to have only a flipping structure.

[0168] To improve the stability of the product during the flipping process, the first side has a first vacuum suction cup 3-4-1 capable of gripping the product. The first vacuum suction cup 3-4-1 can be connected to a vacuum generating device, thereby enabling the first vacuum suction cup 3-4-1 to adsorb and release the product.

[0169] Of course, positioning devices, such as positioning buckles, can also be installed on the flip structure to position the product on the first surface. These will not be elaborated upon here, and are all within the scope of protection.

[0170] Specifically, in order to improve lifting stability, one of the flipping lifting component 3-1 and the lifting base 3-2 has a slide rail 3-8, and the extension direction of the slide rail 3-8 is the same as the driving direction of the lifting drive device 3-3 (for example, both are Z-direction); the other of the flipping lifting component 3-1 and the lifting base 3-2 slides in cooperation with the slide rail 3-8.

[0171] Furthermore, a buffer 3-7 is provided between the flipping lifting component 3-1 and the lifting base 3-2. By providing the buffer 3-7, the impact force on the product during the flipping process is reduced, and the safety of the product during the flipping process is improved.

[0172] Specifically, the flipping plate 3-4 is rotatably connected to the flipping lifting component 3-1 via a rotating shaft 3-9; the axial direction of the rotating shaft 3-9 is perpendicular to the lifting direction of the flipping lifting component 3-1. Of course, the rotating shaft 3-9 can also be set at a certain tilt angle.

[0173] To improve the positioning accuracy of the product on the flip structure, the flip structure also includes a first alignment device 3-5 for positioning and adjusting the product on the flip plate 3-4.

[0174] In this embodiment, the first alignment device 3-5 includes a support plate 3-5-1, a first positioning component 3-5-2, a first positioning drive device 3-5-3, and a second positioning component 3-5-4. The support plate 3-5-1 is connected to the flipping and lifting component 3-1. The first positioning component 3-5-2 is fixedly mounted on the support plate 3-5-1, and its positioning part can make positioning contact with the first edge of the product (e.g., the long side of a mobile phone glass back cover). The second positioning component 3-5-4 is movably mounted on the support plate 3-5-1, and its positioning part can make positioning contact with the second edge of the product (e.g., the short side of a mobile phone glass back cover). The first edge and the second edge are located at different positions on the product. The first positioning drive device 3-5-3 can drive the second positioning component 3-5-4 to switch between a third state and a fourth state.

[0175] In the third state, the positioning part of the second positioning component 3-5-4 is far away from the second edge of the product on the first surface;

[0176] In the fourth state, the positioning part of the second positioning component 3-5-4 contacts the second edge of the product on the first surface and pushes the product to the preset position.

[0177] Alternatively, the first positioning component 3-5-2 can be movably mounted on the support plate 3-5-1.

[0178] To ensure the product is placed correctly, the flipping assembly 3 also includes a detection device;

[0179] The detection device includes: a first detection component 3-11 for detecting whether there is a product on the first side; and / or a second detection component 3-12 for detecting whether the product placement orientation on the first side is correct.

[0180] Taking a glass back cover as an example, the first detection component 3-11 can be used to detect whether the glass back cover is placed on the first side, and the second detection component 3-12 can be used to detect whether the through hole of the glass back cover for installing the camera corresponds to the detection position of the second detection component 3-12.

[0181] like Figure 3As shown, the transmission component 8 includes a platform assembly and a moving pick-and-place component. The platform assembly includes a linear transmission device 8-1 and platforms 8-2 mounted on the linear transmission device 8-1. Each platform 8-2 has a bearing surface for carrying products, and there are multiple platforms 8-2. The moving pick-and-place component can move products between two platforms 8-2. This arrangement ensures that products are stably placed at specific workstations. For example, if a platform 8-2 is set at a cleaning workstation corresponding to a cleaning component, when a product is placed on the bearing surface of the platform 8-2 at that workstation via the moving pick-and-place component or other transmission equipment (such as the flipping component 3), the product at that position can be effectively supported, ensuring the cleaning effect of the cleaning component.

[0182] Specifically, the bearing surface has a second vacuum suction cup 8-2-2-1 capable of gripping the product; a vacuum generating device 8-2-6 connected to the second vacuum suction cup 8-2-2-1 is disposed inside the platform frame 8-2-1.

[0183] Of course, the transmission component 8 can also be set as a transmission belt or transmission roller, as long as it can realize product transmission and positioning.

[0184] like Figure 4 As shown, the platform 8-2 includes a platform frame 8-2-1 and a platform support plate 8-2-2 disposed on the top of the platform frame 8-2-1. The platform frame 8-2-1 is disposed on the linear transmission device 8-1; the bearing surface is the upward-facing side of the platform support plate 8-2-2.

[0185] In this embodiment, multiple platform support plates 8-2-2 (such as...) can be installed on the platform frame 8-2-1. Figure 4 (As shown in the two examples), so that multiple products can be cleaned at the same time, thus improving cleaning efficiency.

[0186] Preferably, the bearing surface has a second vacuum suction cup 8-2-2-1 capable of gripping the product; a vacuum generating device 8-2-6 connected to the second vacuum suction cup 8-2-2-1 is disposed inside the platform frame 8-2-1. This arrangement improves structural compactness. Of course, structures such as clips for positioning the product can also be provided on the bearing surface, which are also within the scope of protection.

[0187] Furthermore, in order to reduce the likelihood of the product being damaged by compressive forces (such as the wiping force applied to the product by the cleaning components), the platform support plate 8-2-2 and the platform frame 8-2-1 are connected by a buffer device 8-2-5.

[0188] Furthermore, the stage 8-2 also includes a second alignment device for positioning and adjusting the product on the bearing surface. By providing the second alignment device, the positioning and adjustment of the product on the bearing surface is facilitated, thereby improving the accuracy of the cleaning components in cleaning the product.

[0189] Specifically, the second alignment device includes a third positioning component 8-2-3 fixedly mounted on the top of the platform 8-2-1, a fourth positioning component 8-2-4 movably mounted on the top of the platform 8-2-1, and a second positioning drive device capable of driving the fourth positioning component 8-2-4 to switch between a fifth state and a sixth state. The positioning part of the third positioning component 8-2-3 can make positioning contact with the first edge of the product; the positioning part of the fourth positioning component 8-2-4 can make positioning contact with the second edge of the product, with the first edge and the second edge located at different positions on the product.

[0190] Specifically, in the fifth state, the positioning part of the third positioning component 8-2-3 is away from the second edge of the product on the bearing surface; in the sixth state, the positioning part of the third positioning component 8-2-3 contacts the second edge of the product on the bearing surface and pushes the product to a preset position.

[0191] like Figure 5 and Figure 6 As shown, the pallet loading module 1 and / or pallet unloading module 14 include: a support frame 1-7; a conveyor belt 1-1 disposed on the support frame 1-7, on which pallets can be placed; and a pallet lifting assembly disposed at the output end of the conveyor belt 1-1, which can lift the pallet transferred to the output end of the conveyor belt 1-1 to a predetermined height.

[0192] The above-described design allows for pallet height adjustment, preventing pallets from interfering with product transport. The pallet lifting assembly also facilitates adjustments to the layout of the pallet transport structure (empty pallet transport assembly), ensuring uninterrupted product transport and without increasing the floor space required for the cleaning system.

[0193] Furthermore, the pallet lifting assembly includes a pallet lifting component 1-3, positioning posts 1-5, and a lifting component 1-6 connected to the drive end of the pallet lifting component 1-3. The pallet lifting component 1-3 is fixed relative to the support frame 1-7; the lifting component 1-6 can contact the bottom of the pallet being conveyed to the output end of the conveyor belt 1-1; the positioning posts 1-5 are fixed relative to the support frame 1-7 and can make positioning contact with the edge of the pallet. In this embodiment, there are multiple positioning posts 1-5 that can form a channel for the pallet to move up and down, and the positioning contact between the positioning posts 1-5 and the edge of the pallet prevents the pallet from flipping over or moving out of the channel. It also facilitates the operator's movement through the pallet within the channel.

[0194] Furthermore, the pallet lifting assembly also includes a precision positioning component (not shown); the precision positioning component is used to position and adjust the pallet on the lifting components 1-6.

[0195] The pallet lifting assembly also includes a pallet separation assembly; the pallet separation assembly is used to position any one of the multiple stacked pallets on the lifting components 1-6. That is, the pallet separation assembly can divide the multiple stacked pallets into two parts: one part consists of any one of the multiple stacked pallets positioned by the pallet separation assembly and the pallets stacked on top of it, while the other part of the pallets separates from the aforementioned part of the pallets under the action of gravity.

[0196] Specifically, the tray separation assembly includes a first linear drive device and a tray separating component. The first linear drive device is driven in a horizontal direction; the tray separating component is connected to the drive end of the first linear drive device, and the end of the tray separating component facing the lifting components 1-6 has a tray separating surface that can be inserted between the edges of two adjacent trays and can contact the edges of the trays.

[0197] like Figure 7 As shown, the product loading module 2 provided in this embodiment of the invention includes a first driving device 2-1, a second driving device 2-3, a product lifting device 2-4, and a product gripping device 2-5 for gripping products. The driving direction of the first driving device 2-1 is a first direction (e.g., the Y-axis direction), and the main structure of the first driving device 2-1 is fixed relative to the overall frame of the cleaning system; the driving direction of the second driving device 2-3 is a second direction (e.g., the X-axis direction), the first direction and the second direction are perpendicular to each other and both are horizontal, and the main structure of the second driving device 2-3 is connected to the driving end of the first driving device 2-1; the main structure of the product lifting device 2-4 is connected to the driving end of the second driving device 2-3; and the product gripping device 2-5 is connected to the driving end of the product lifting device 2-4.

[0198] The product unloading module 13 can have the same structure as the product loading module 2 described above. Of course, it can also be different. It only needs to satisfy the loading and unloading operations.

[0199] like Figure 8 As shown, the product unloading module 13 also has a cleaning detection device 2-6; the cleaning detection device 2-6 is used to detect whether the product gripping device 2-5 of the product unloading module 13 is clean and qualified. Among them, the cleaning detection device 2-6 can detect whether the product is clean enough, so as to distinguish and place the products separately, that is, to separate qualified products from unqualified products.

[0200] Of course, the product unloading module 13 can also be equipped with devices such as barcode readers that can identify product information, so as to place the products accordingly.

[0201] Furthermore, the cleaning detection device 2-6 is communicatively connected to the first drive device 2-1, the second drive device 2-3, and the product lifting device 2-4; when the cleaning detection device 2-6 detects that the product gripping device 2-5 of the product unloading module 13 is clean and qualified, the first drive device 2-1, the second drive device 2-3, and the product lifting device 2-4 can control the product gripping device 2-5 to transfer to the tray of the first unloading position.

[0202] like Figure 1 and Figure 9 As shown, the cleaning system provided in this embodiment of the invention also includes a discharge module 12, which includes a discharge transmission line 12-1 capable of transmitting products.

[0203] When the cleaning detection device 2-6 detects that the product gripping device 2-5 of the product unloading module 13 is not clean enough, the first drive device 2-1, the second drive device 2-3 and the product lifting device 2-4 can control the product gripping device 2-5 to transfer to the discharge transmission line 12-1.

[0204] Furthermore, the product gripping device 2-5 has at least two gripping parts, each of which can grip one product; the discharge module 12 also includes multiple buffer platforms 12-2, which are mounted above the discharge transmission line 12-1, and there is a gap between the buffer platform 12-2 and the discharge transmission line 12-1 that allows products to pass through the discharge transmission line 12-1;

[0205] When the cleaning detection device 2-6 detects that at least two products grabbed by the product gripping device 2-5 of the product unloading module 13 have a portion that is clean and a portion that is not clean, the first drive device 2-1, the second drive device 2-3 and the product lifting device 2-4 can control the product gripping device 2-5 to transfer the cleaned products to the buffer platform 12-2 and the uncleaned products to the discharge transmission line 12-1.

[0206] There is at least one cache platform group among all cache platforms 12-2, and the number of cache platforms 12-2 in the cache platform group is at least two; all the grabbing parts of the product grabbing device 2-5 can correspond one-to-one with all the cache platforms 12-2 in the cache platform group.

[0207] To facilitate automated monitoring, the cleaning data detected by the cleaning detection devices 2-6 can be saved locally or uploaded to the server for production scheduling and management.

[0208] like Figure 1 As shown, the cleaning component provided in this embodiment of the invention includes:

[0209] First wet cleaning device 4 for wet wiping the raised surface of a product;

[0210] The first dry cleaning device 5 is used for dry cleaning the raised surface of the product. The first dry cleaning device 5 is located on the side of the first wet cleaning device 4 away from the product input station.

[0211] Second wet cleaning device 6 for wet wiping the edge of the protrusion of the product;

[0212] The second dry cleaning device 7 is used for dry cleaning the edge of the boss of the product. The second dry cleaning device 7 is located on the side of the second wet cleaning device 6 away from the product input station.

[0213] A third wet-wiping cleaning device 9 for large surfaces of wet-wiping products;

[0214] A third dry cleaning device 10 for dry-wiping products is located on the side of the third wet cleaning device 9 away from the product input station.

[0215] That is, the raised surface, raised edge, and large surface of the product are all wiped with wet and dry using different devices, thereby enabling different parts of the product to be wiped according to different needs, effectively improving the cleaning effect of the product.

[0216] like Figure 1 and Figure 10 As shown, the cleaning assembly includes a first cleaning device;

[0217] The first cleaning device includes a first support, a first cleaning drive device 4-1, a first cleaning lifting drive device 4-9, and a first wiping head 4-10. The first support is movable relative to the transmission assembly 8 along a third direction, which is perpendicular to the direction in which the transmission assembly 8 transmits the product.

[0218] The first cleaning drive device 4-1 drives the first support to move along a third direction; the main structure of the first cleaning lifting drive device 4-9 is connected to the first support; the first wiping head 4-10 is disposed at the drive end of the first cleaning lifting drive device 4-9. The first wiping head 4-10 can move horizontally or vertically under the drive of the cleaning drive device 4-1 and the first cleaning lifting drive device 4-9 to wipe the raised surface of the product and the edge of the raised surface. For example, if the product is a mobile phone glass back cover and the raised surface is a raised ring corresponding to the mobile phone camera, the first wiping head 4-10, under the control of the drive device, first wipes the raised surface of the glass back cover, then moves to the periphery of the raised surface and moves along the edge of the raised surface to wipe the edge of the raised surface; when wiping the raised surface, it can wipe back and forth; when wiping the edge of the raised surface, the first wiping head 4-10 can abut against and rotate along the raised surface to wipe the periphery of the raised surface. The end of the first wiping head 4-10 can be cylindrical, which is convenient for wiping the flat surface of the boss, and also convenient for wiping the edge of the boss by rotating around it.

[0219] Specifically, the aforementioned third direction is the Z direction, the direction of the transmission component 8 in transmitting the product is the Y direction, and the direction of the pallet loading module 1 and / or the pallet unloading module 14 in conveying the pallet is the X direction.

[0220] In this embodiment of the invention, the first wiping head 4-10 may be a contour wiping head, and the specific shape of the contour wiping head may be determined according to the shape of the protrusion of the product.

[0221] Furthermore, the first wiping head 4-10 can be vibrated during the wiping process to achieve biomimetic wiping, which can effectively improve the cleaning effect.

[0222] The first cleaning device also includes a first take-up roll 4-2 and a first unload roll 4-7. The first take-up roll 4-2 is rotatably mounted on the first support. The first unload roll 4-7 is rotatably mounted on the first support. A wiping cloth for wiping the product is transferred between the first take-up roll 4-2 and the first unload roll 4-7.

[0223] Specifically, the first wiping head 4-10 can contact the wiping cloth through the lifting movement of the first cleaning lifting drive device 4-9, thereby pushing the wiping cloth to contact the product. During this process, the wiping cloth is transferred between the first take-up roll 4-2 and the first unload roll 4-7 to ensure that the wiping cloth is always in contact with the product, thereby effectively improving the wiping effect.

[0224] Specifically, the first cleaning device also includes a first driving device 4-4 (motor), and the shaft 4-3 of the first take-up roll 4-2 is connected to the drive end of the first driving device 4-4 via a conveyor belt; the first cleaning device also includes a second driving device 4-5 (motor), and the shaft 4-6 of the second take-up roll 4-7 is connected to the drive end of the second driving device 4-5 via a conveyor belt.

[0225] In this embodiment of the invention, the first cleaning device may be provided with two first wiping heads 4-10, one for wet wiping (wiping cloth sprayed with cleaning liquid) the surface of the boss, and the other for dry wiping (wiping cloth is dry) the surface of the boss; the number of the first cleaning devices may be two, one for wet wiping and dry wiping the surface of the product boss, and the other for wet wiping and dry wiping the edge of the product boss.

[0226] Among them, the boss plane is the side of the boss that faces the same direction as the large surface of the product, and the edge of the boss is the side of the boss that connects the boss plane and the large surface of the product.

[0227] Of course, the number of first cleaning devices can also be set to four, and the four first cleaning devices are as follows: Figure 1 The diagram shows a first wet cleaning device 4, a first dry cleaning device 5, a second wet cleaning device 6, and a second dry cleaning device 7. Each of these devices has an independent first wiping head 4-10. Specifically, the first wiping head 4-10 of the first wet cleaning device 4 is used for wet wiping the surface of the boss, and the first wiping head 4-10 of the first dry cleaning device 5 is used for dry wiping the surface of the boss; the first wiping head 4-10 of the second wet cleaning device 6 is used for wet wiping the edge of the boss, and the first wiping head 4-10 of the second dry cleaning device 7 is used for dry wiping the edge of the boss.

[0228] like Figure 1 and Figure 11 As shown, the cleaning assembly includes a second cleaning device;

[0229] The second cleaning device includes a second support, a second unloading roll 9-2, a second take-up roll 9-4, a second cleaning lifting drive device 9-7, and a second wiping head 9-8. The second support is fixed relative to the transmission assembly 8; the second unloading roll 9-2 is rotatably mounted on the second support; the second take-up roll 9-4 is rotatably mounted on the second support, and a wiping cloth for wiping the product is transferred between the second unloading roll 9-2 and the second take-up roll 9-4; the main structure of the second cleaning lifting drive device 9-7 is connected to the second support; the second wiping head 9-8 is located at the drive end of the second cleaning lifting drive device 9-7, and the end of the second wiping head 9-8 facing the product being conveyed by the transmission assembly 8 contacts the wiping cloth.

[0230] Preferably, the second wiping head 9-8 is a vibrating wiping head. That is, the second wiping head 9-8 adopts a contour-following wiping head, and the second wiping head 9-8 uses a vibrating method during wiping to achieve biomimetic wiping, which can effectively improve the cleaning effect.

[0231] To further improve the cleaning effect, the second cleaning device has a wet wiping station and a dry wiping station;

[0232] There are two second cleaning lifting drive devices 9-7, namely a second wet wiping lifting drive device corresponding to the wet wiping station and a second dry wiping lifting drive device corresponding to the dry wiping station.

[0233] There are two second wiping heads 9-8, namely a second wet wiping head installed on the second wet wiping lifting drive device and a second dry wiping head installed on the second dry wiping lifting drive device;

[0234] The second cleaning device also includes a cleaning liquid spraying device 9-9, which is configured corresponding to the second wet wiping head and is used to wet the wiping cloth area in contact with the second wet wiping head.

[0235] Of course, you can also set up only wet wiping stations or only dry wiping stations. The specific setup depends on the cleaning needs of the product, and there are no specific restrictions here.

[0236] To improve structural compactness, the second cleaning device also includes a transfer and gripping device 9-10 located between the wet wiping station and the dry wiping station.

[0237] In one specific embodiment, the second cleaning device has two independently driveable second wiping heads 9-8. The second wiping head 9-8 near the take-up roll 9-4 is a wet wiping head, and the second wiping head 9-8 near the unload roll 9-2 is a dry wiping head. At the wet wiping station (near the take-up roll 9-4), the cleaning liquid spraying device 9-9 sprays cleaning liquid onto the wiping cloth at the wet wiping station, and then the wet wiping head drives the wiping cloth to wet-wipe the large surface of the product (the large surface of the glass back cover). After wet wiping, the transfer and gripping device 9-10 transfers the wet-wiped product to the dry wiping station (near the unload roll 9-2), and then the dry wiping head drives the wiping cloth to dry-wipe the large surface of the product (the large surface of the glass back cover). This allows for both wet and dry wiping of the large surface of the product.

[0238] Alternatively, two second cleaning devices can be used, each with its own independent second wiping head 9-8. One second cleaning device's second wiping head 9-8 is used for wet wiping of the product's main surface, while the other second cleaning device's second wiping head 9-8 is used for dry wiping of the product's main surface.

[0239] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
