[0052] 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.

[0053] like Figure 1-Figure 19 A single-station multi-surface visual inspection device is shown, comprising a loading and cleaning machine, an AOI inspection machine and a unloading machine.

The large surface cleaning assembly and the side and R-angle cleaning assembly are arranged side by side, and the conveying assembly is arranged on the same side of the large surface cleaning assembly and the side and R-angle cleaning assembly. The product to be cleaned is transported from the large surface cleaning assembly to the side and R-angle cleaning assembly through the conveying assembly in a "C"-shaped path for cleaning; the loading channel assembly is arranged in the front of the large surface cleaning assembly, responsible for product loading, and transferring the product to the robot picking position; the flipping assembly is arranged in the back of the side and R-angle cleaning assembly, responsible for turning the product over and waiting for AOI to transport and unload.

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.

[0056] 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.

[0057] 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.

[0058] 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.

[0061] 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.
