[0043] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0044] like Figure 1-Figure 12The front and side cleaning device of a PAD back shell shown in the figure includes a feed channel component 1-1, a large surface cleaning component 1-2, a conveying component 1-3, a side and R corner cleaning component 1-4, a flipping component 1-5, a first cleaning and transplanting module 1-6, a second cleaning and transplanting module 1-7, a material picking robot 1-8 and a visual guidance component 1-9; the entire component structure is assembled in sequence according to a "C" type assembly machine: feed channel component, large surface cleaning component, conveying component, side and R corner cleaning component, flipping component. The large surface cleaning component and the side and R corner cleaning component are arranged side by side, and the conveying component is arranged on the same side of the large surface cleaning component and the side and R corner cleaning component. The product to be cleaned is transported from the large surface cleaning component to the side and R corner cleaning component through the conveying component in a "C"-shaped path for cleaning; the loading flow channel component is arranged in the front channel of the large surface cleaning component, and is responsible for product loading and transferring the product to the robot picking position; the flipping component is arranged in the back channel of the side and R corner cleaning component, and is responsible for turning the product over and waiting for AOI to transport and unload.

[0045] The feeding channel assembly 1-1 includes a belt flow line 1-11; ribs 1-12 are arranged on both sides of the belt flow line; and a material arrival sensing photoelectric 1-13 and a stopper 1-14 are arranged at the end of the belt flow line. The product starts to be fed through the belt flow line, and touches the stopper when it reaches the end of the belt flow line, triggering the material arrival sensing photoelectric operation; a material picking manipulator is arranged above the belt flow line. After the product is in place, the material arrival sensing photoelectric sends a material picking signal, and the control system enables the material picking manipulator to vacuum absorb the product to be cleaned and flip it over to feed it to the large surface cleaning assembly. The ribs on both sides of the belt flow line can guide well and prevent the product from being offset when feeding.

[0046] A first cleaning and transplanting module 1-6 is arranged below the large surface cleaning component 1-2, and the first cleaning and transplanting module includes a large surface cleaning linear slide 1-61 and a vacuum adsorption jig 1-62 arranged on the large surface cleaning linear slide; the material picking robot places the product on the vacuum adsorption jig, and the product is sent to the large surface cleaning component through the large surface cleaning linear slide to start cleaning.

[0047] The large surface cleaning assembly 1-2 includes a large surface cleaning grinding head assembly 1-21 and a cloth rolling mechanism 1-22; the large surface cleaning grinding head assembly includes a grinding head mounting plate 1-23, and a large body cleaning grinding head 1-24 is arranged at the bottom of the grinding head mounting plate; the grinding head mounting plate has an opening 1-25, and a logo cleaning grinding head 1-26 is arranged in the opening, and a camera cleaning grinding head 1-27 is also arranged on one side of the mounting plate; the logo cleaning grinding head and the camera cleaning grinding head are respectively connected with a lifting assembly 1-28; when the large surface is wet wiped, the logo cleaning grinding head and the camera cleaning grinding head are raised by the lifting assembly to avoid. The grinding head is divided into three parts, the logo cleaning grinding head, the camera cleaning grinding head and the large body cleaning grinding head. The three parts of the grinding head can be independently retracted, so that when wet wiping is performed, the logo cleaning grinding head and the camera cleaning grinding head can be achieved without contacting the product, thereby effectively avoiding the damage of the cleaning liquid to the logo and the camera, and further improving the cleaning effect.

[0048] The transport component 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 component to the side and R corner cleaning component through vacuum adsorption.

The alcohol nozzle and the side cleaning grinding head are arranged at the same height, which can ensure that the sprayed alcohol liquid soaks the dust-free cloth well and the soaking position is just the position that needs to be cleaned; an alcohol tank 1-46 is also arranged on the fixed plate, below the alcohol nozzle and the side cleaning grinding head, which can further collect residual alcohol liquid to prevent damage to other electrical components. The fixed plate is also connected to the pressure sensor 1-47 through a telescopic component, and the telescopic component can be a telescopic cylinder or others.

[0051] The flip assembly 1-5 includes a lifting Z axis 1-51 and a flip arm 1-52 arranged on the lifting Z axis, and a connecting block 1-53 is arranged on the flip arm; waist grooves 1-54 are arranged at both ends of the connecting block, and a vacuum suction cup 1-56 is connected to the waist groove through a threaded rod 1-55; a two-way nut 1-57 is arranged on the threaded rod, and the threaded rod is locked and connected to the connecting block through the two-way nut. Through the setting of the waist groove, the position of the threaded rod can be freely fixed according to actual needs to adapt to products of different sizes; at the same time, the diameter of the two-way nut is larger than the aperture of the waist groove, and the outer diameter of the threaded rod is smaller than the aperture of the waist groove, so that the threaded section of the threaded rod can be located in the waist groove, and the two-way nut is locked from the upper and lower directions, which not only eliminates the need for other fasteners during connection, but also makes adjustment more convenient.
