Embodiment 1
[0039] A barcode reading module with an inductive braking component and a reading method, such as Figure 1-3 shown, including:
[0040] Housing 1, the housing 1 is sequentially provided with a first lens opening 111 , a first aiming opening 121 , and a first lighting opening 131 passing through the front and rear ends of the housing 1 in the horizontal direction of the front end;
[0041] The circuit board 2 includes at least one PCB board, and the circuit board is installed at the rear end of the housing 1. On the front of the circuit board 2, an inductor 14, an imaging component socket 112, an aiming light source component 12, Illumination light source assembly 13; the imaging assembly socket 112 is pluggably connected with a convex imaging assembly 11; a processor with barcode decoding capability is arranged on the back of the circuit 2, and an electrical signal transmission with the outside transmission interface;
[0042] The movable panel 3, the movable panel 3 is loc...
Embodiment 2
[0054] A barcode reading method, comprising the following steps:
[0055] S1: the aiming light source assembly 12 emits an aiming light pattern to the target surface;
[0056] S2: The imaging component 11 acquires a first target surface image with an aiming light pattern;
[0057] S3: Calculate the proportion of pixels occupied by the aiming light pattern in the target surface image, and when the proportion is greater than a threshold, the processor uses the first target surface image obtained in step S2 to decode; when the proportion When it is less than the threshold, go to step S4;
[0058] S4: the inductor 14 is energized and generates a magnetic pole, which generates a reaction force with the magnet 6 at the corresponding position, pushing the magnet 6 to be displaced along the axial direction, and driving the movable panel 3 to be displaced;
[0059] In step S4, change the current passing through the inductance 14 through the electronic device, and switch the magnetic ...
