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 ...

Abstract

The invention discloses a bar code reading module with an inductor braking assembly and a reading method. The bar code reading module comprises a shell and a circuit board at a back end of the shell, wherein the circuit board bears electronic devices such as an imaging assembly, a lighting assembly, an aiming assembly and an inductor; a movable panel is arranged at a front end of the shell; the movable panel is provided with a lens window, an aiming window and a lighting window corresponding to the shell; and one end of the movable panel is connected with one end of the shell, and the other end of the movable panel is provided with a magnet corresponding to the inductor. According to the invention, through energization of the inductor and changes of current directions, the inductor generates a variable magnetic pole to act with the magnet to drive the movable panel to move, so that a depth of field of the imaging assembly and an illumination range of the lighting assembly are changed.

Description

technical field [0001] The invention relates to a barcode reading module, in particular to a barcode reading module with an inductive braking component and a reading method. Background technique [0002] With the wide application of barcode applications in logistics, warehousing, retail and other fields, more and more companies begin to use barcode scanning equipment to improve work efficiency. Common barcode scanning equipment includes handheld barcode scanning equipment, fixed barcode scanning terminals and mobile data terminals, etc. Handheld barcode scanning devices and fixed barcode scanning terminals are often used in supermarkets, home appliance stores and other places. Sales assistance and product management assistance are realized by scanning the barcode of the product itself. Mobile data terminals are often used in the field of logistics. By scanning the corresponding barcodes, logistics transportation records and inventory management can be realized. The core o...
