Description

TECHNICAL FIELD

[0001] The utility model relates to screw mark technical field, specifically a screw mark printing machine. BACKGROUND

[0002] Screw and its matched nut, gasket etc. are one of the most basic and widely used components in mechanical and electronic industries, mainly used for the connection and fixation of mechanical parts, and the connection of wire joints. There are various types of bolts, and their materials, strength grades and purposes are different. Common bolt materials include carbon steel, stainless steel, aluminum alloy, titanium alloy, etc. Different materials endow bolts with different performance characteristics, such as strength, corrosion resistance, high temperature resistance, etc. In some special environments, such as high temperature and corrosive environment, bolts with special properties are required.

[0003] In order to ensure the correct identification and use of bolts in different application scenarios, it is particularly important to mark them clearly and accurately. For example, in new energy vehicles, especially in key parts such as batteries and motors, screws with good corrosion resistance are required, such as stainless steel screws or screws with special surface treatment (such as galvanizing, nickel plating, etc.). In addition, the motor, battery and other components will generate high temperature during work, so the screw is required to maintain good mechanical properties at high temperature and not to deform or decrease in strength. Therefore, materials such as titanium alloy and high-strength stainless steel are often used. In the installation and maintenance process of new energy vehicles, it is crucial to choose the right screw, not only considering the physical properties of the screw, but also considering its compatibility with the surrounding materials to ensure the safe and reliable operation of the vehicle. Therefore, marking the screw to indicate its application occasion and special performance becomes a key step to ensure correct use.

[0004] However, the existing marking method usually relies on manual marking on the surface of the screw, which is inefficient and prone to errors. In order to improve the efficiency and accuracy of marking, it is particularly necessary to develop a technology that can automatically and efficiently mark the screw. UTILITY MODEL CONTENTS
