This type of equipment is usually equipped with a laser marker and inkjet printer, providing a comprehensive solution for circuit board identification and quality traceability. In order to improve the efficiency of circuit board dotting and blackening, a laser head is required, but existing laser heads still have the following shortcomings:

[0003] For example, the utility model with application number 202122420320.0 discloses an FPC fully automatic coaxial light laser marking machine. The utility model can suck dust particles on the flexible circuit board into the dust collecting box through the cooperation of structures such as the dust hood, air inlet pipe, exhaust fan and dust collecting box, which is convenient for collecting and processing dust, thereby realizing the dust removal operation of the flexible circuit board. At the same time, through the cooperation of the inner screw sleeve and the outer screw sleeve, the dust hood can be disassembled and replaced, which greatly improves the practicality of the device. However, similar to the comparative documents of the above-mentioned application, when the existing laser head is used, since most laser heads need to be constantly moved in accordance with the marking position, the laser head is prone to touch some equipment or materials during movement, causing the laser head to be easily damaged by collision, resulting in reduced practicality of the laser head and reduced utilization efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-collision laser head for a circuit board blackening machine is proposed. Utility Model Content
