Description

Technical Field

[0001] The utility model relates to the technical field of laser scanning guns, in particular to a laser head of a scanning gun which is easy to disassemble. Background Art

[0002] The laser head is a very important component in a laser scanner. It is usually located inside the scanner, near the scanning window of the scanner. This is because the laser head needs to project the laser beam onto the barcode and read the reflected light through the window. The laser scanner is a sophisticated electronic device.

[0003] Since the traditional laser scanning head is located inside the scanning gun and the outer shell of the scanning gun is not easy to disassemble and install, a special disassembly screwdriver or other disassembly tools is required to disassemble and install the outer shell, so as to repair, inspect or replace the internal laser scanning head. The use of special disassembly screwdrivers or other disassembly tools to disassemble and install the outer shell is time-consuming and labor-intensive, and has low efficiency. In addition, the laser scanning head and the circuit motherboard of the scanning gun are generally connected by a cable or welding. If it is connected by a cable, the cable needs to be carefully pulled out from the motherboard. If it is welded, a tool such as a soldering iron needs to be used to disconnect the welding point, which further increases the difficulty of disassembling the laser scanning head.
