Description

Technical Field

[0001] The present invention relates to the technical field of keyboard conveying, and particularly relates to a conveying device and method for keyboard spraying and processing. Background Art

[0002] Keyboard spraying is a process for surface coating treatment of the keyboard housing, usually to improve the appearance of the keyboard or enhance its durability. This process can include applying different colors, patterns, or even matte, smooth, or fingerprint-resistant coatings. The materials used for spraying are often professional paints or coating agents, which not only have a decorative effect but also provide some protection for the keyboard.

[0003] When the existing keyboard is automatically sprayed, multiple keyboards are generally conveyed to the inside of the spraying machine through a chain conveyor. Since there may be dirt or dust on the surface of the keyboard during the transfer process, the chain conveyor cannot timely clean the dirt or dust from the surface of the keyboard, which affects the spraying effect of the keyboard after being conveyed to the inside of the spraying machine, resulting in poor spraying uniformity. Moreover, the chain will sag under gravity, which also affects the height uniformity of multiple keyboards conveyed to the inside of the spraying machine. For this reason, we propose a conveying device and method for keyboard spraying and processing. Summary of the Invention

[0004] The purpose of the present invention is to provide a conveying device and method for keyboard spraying and processing to solve the problems raised in the above background art.
