In fact, the barcode scanner module, like the barcode scanner gun, has the function of scanning the barcode. It's just that the working environment of the barcode scanner is more inclined to the surface type, such as the cashier work in major supermarkets and express scanning express orders. The application of barcode scanning modules is relatively invisible. Generally, they are built into some kind of machine. The most common ones in our lives are the group purchase automatic ticket machines in cinemas, vending machines in subway stations, and residential areas. Or the express self-service storage machine in the school, etc.

The barcode scanning laser module is different from the red light module

The principle of the laser scanning module is to shoot the laser light source point through the internal laser device, hit the reflective sheet with the mechanical structure device, and then rely on the vibration motor to oscillate the laser point to the laser line on the barcode, and then decode it into AD. Digital signal.

The red light scanning module usually uses an LED light-emitting diode light source, and is converted by a photoelectric signal through a CCD photosensitive element.

Most laser scanning modules rely on distribution to hold the machine in place to make equipment, so are prone to damage when swinging and the pendulum disassembled. Therefore, we can often see that some laser guns that are scanned after falling are a point. , yielding fairly high returns.

There is no mechanical structure in the middle of the red light scanning module, so the drop resistance is comparable to that of the laser, so the stability is better, and the repair rate of the red light scanning module is much lower than that of the laser scanning module.
