[0043] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0044] like Figures 1-12The illustrated PAD back cover cleaning device includes a feeding channel assembly 1-1, a large-area cleaning assembly 1-2, a conveying assembly 1-3, a side and round-corner cleaning assembly 1-4, a flipping assembly 1-5, a first cleaning and transfer module 1-6, a second cleaning and transfer module 1-7, a material handling robot 1-8, and a vision guidance assembly 1-9. The entire assembly structure is arranged in a "C" shape, with the feeding channel assembly, large-area cleaning assembly, conveying assembly, side and round-corner cleaning assembly, and flipping assembly assembled sequentially. The large-area cleaning assembly and the side and round-corner cleaning assembly are arranged side-by-side. The conveying assembly is located on the same side as the large-area cleaning assembly and the side and round-corner cleaning assembly. The product to be cleaned is transported from the large-area cleaning assembly to the side and round-corner cleaning assembly via the conveying assembly in a "C" shaped path. The feeding channel assembly is located in front of the large-area cleaning assembly and is responsible for feeding the product and transferring it to the robot's pick-up position. The flipping assembly is located behind the side and round-corner cleaning assembly and is responsible for flipping the product over, awaiting AOI (Automated Optical Inspection) unloading.

[0045] The feeding channel assembly 1-1 includes a belt conveyor 1-11; side guards 1-12 are provided on both sides of the belt conveyor; and a material arrival sensor 1-13 and a stop 1-14 are provided at the end of the belt conveyor. The product begins feeding through the belt conveyor and touches the stop at the end of the conveyor, triggering the material arrival sensor. A robotic arm is positioned above the belt conveyor. After the product arrives, the material arrival sensor sends a picking signal, and the control system causes the robotic arm to vacuum-adsorb the product to be cleaned, flip it, and feed it into the large-area cleaning assembly. The side guards on both sides of the belt conveyor provide good guidance and prevent product deviation during feeding.

[0046] Below the large surface cleaning component 1-2, a first cleaning and transfer module 1-6 is provided. The first cleaning and transfer module includes a large surface cleaning linear slide rail 1-61 and a vacuum adsorption fixture 1-62 set on the large surface cleaning linear slide rail. The picking robot places the product on the vacuum adsorption fixture, and the product is sent to the large surface cleaning component through the large surface cleaning linear slide rail to start cleaning.

[0047] The large-area cleaning assembly 1-2 includes a large-area cleaning grinding head assembly 1-21 and a cloth rolling mechanism 1-22. The large-area cleaning grinding head assembly includes a grinding head mounting plate 1-23, with a large-body cleaning grinding head 1-24 positioned at the bottom of the mounting plate. The mounting plate has an opening 1-25, within which a logo cleaning grinding head 1-26 is positioned. A camera cleaning grinding head 1-27 is also positioned on one side of the mounting plate. The logo cleaning grinding head and the camera cleaning grinding head are respectively connected to lifting components 1-28. During wet cleaning of the large area, the logo cleaning grinding head and the camera cleaning grinding head rise via the lifting components to avoid contact with the product. The grinding head is divided into three parts: a logo cleaning grinding head, a camera cleaning grinding head, and a large-body cleaning grinding head. These three parts can extend and retract independently, ensuring that the logo cleaning grinding head and the camera cleaning grinding head do not contact the product during wet cleaning. This effectively prevents damage to the logo and camera from the cleaning fluid and further improves the cleaning effect.

[0048] The transport assembly 1-3 includes a transport bracket 1-31, on which a transport X-axis 1-32 and a transport Z-axis 1-33 are provided; the transport Z-axis transports the product from the large surface cleaning assembly to the side and R-corner cleaning assembly through vacuum adsorption.

[0049] The side and corner cleaning components 1-4 include two sets, and a second cleaning and transfer module 1-7 is arranged between the two sets of side and corner cleaning components; the second cleaning and transfer module includes a side and corner cleaning linear slide rail and a vacuum adsorption fixture arranged on the side and corner cleaning linear slide rail; the product to be cleaned is placed on the vacuum adsorption fixture and transferred by the corner cleaning linear slide rail.

[0050] The side and round-corner cleaning assembly 1-4 includes a cloth rolling mechanism and a side cleaning grinding head assembly 1-41. The side cleaning grinding head assembly includes a fixing plate 1-42, on which a side cleaning grinding head 1-43 is mounted. The side cleaning grinding head is a long strip with grooves 1-44. During cleaning, the sides and round-corners of the product can be embedded in the grooves, ensuring more thorough cleaning. An alcohol spray nozzle 1-45 is also mounted on the fixing plate. The side cleaning grinding head can be multi-segmented, so the alcohol spray nozzle can be positioned between the segments. The alcohol spray nozzle is cylindrical, with small openings evenly spaced on its surface for alcohol spraying. The alcohol spray nozzle is positioned at the same height as the side cleaning grinding head, ensuring that the sprayed alcohol effectively wets the lint-free cloth, and that the wetted area precisely corresponds to the area requiring cleaning. An alcohol tank 1-46 is also mounted on the fixing plate, below the alcohol spray nozzle and the side cleaning grinding head, to further collect residual alcohol and prevent damage to other electrical components. The fixed plate is also connected to the pressure sensor 1-47 via a telescopic assembly, which can be a telescopic cylinder or other components.

[0051] The flipping assembly 1-5 includes a lifting Z-axis 1-51 and a flipping arm 1-52 mounted on the lifting Z-axis. A connecting block 1-53 is mounted on the flipping arm. Both ends of the connecting block have waist grooves 1-54. A vacuum suction cup 1-56 is connected to the waist groove via a threaded rod 1-55. The threaded rod has a two-way nut 1-57, which locks the threaded rod to the connecting block. The waist grooves allow for flexible fixing of the threaded rod to accommodate products of different sizes. Furthermore, the diameter of the two-way nut is larger than the diameter of the waist groove, while the outer diameter of the threaded rod is smaller than the diameter of the waist groove. This allows the threaded section of the threaded rod to be positioned within the waist groove, and the two-way nut locks it from both top and bottom, eliminating the need for additional fasteners during connection and making adjustment more convenient.

[0052] The entire cleaning process of the device is as follows:

[0053] 1. The product is manually placed at the feeding port and moved to the robotic arm's picking position through the flow channel;

[0054] 2. After the robotic arm picks up the material, it flips it over and, guided by vision, places the product on a large-area cleaning fixture;

[0055] Large-area cleaning process: Wet the product with a lint-free cloth - wet wipe the large surface of the product (avoiding logos and cameras) - dry wipe the large surface of the product - move the product to the unloading position to await handling and retrieval;

[0056] 3. After the cleaning fixture completes the large-area cleaning of the product, it is moved to the unloading position to await handling and transfer.

[0057] 4. The transport assembly moves the product from the large-area cleaning fixture to the side cleaning fixture; Side & Round Corner Cleaning Process: The product is moved to the side cleaning carrier by the transport assembly - a lint-free cloth is soaked - the long side of the product is wet-wiped - the long side is dry-wiped - the grinding head retracts - the product rotates - the grinding head extends - the two round corners are wet-wiped - the round corners are dry-wiped.

[0058] - Grinding head retracts - Product rotates - Grinding head extends - Short side wet wiping - Short side dry wiping - Grinding head retracts - Product rotates - Grinding head extends - R-angle wet wiping - R-angle dry wiping - Move to the flipping and picking position - Wait for the lifting and flipping to pick up the material;

[0059] 5. After the side cleaning fixture completes the side cleaning of the product, it moves to the flipping and picking position;

[0060] 6. Flip the component to flip the product and wait for it to be unloaded.
