Embodiment Construction

[0035] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0036] A lighting module of a barcode reading device, used for supplementary lighting of a reading head, including a lighting source 3, a condenser lens 2, a camera module 4, a fixed bracket and a bottom plate (the bottom plate is not shown); the described The whole lighting module is fixed on the base plate through the fixing bracket. The base plate can be a PCB board, a flexible circuit board, etc. The circuit can be etched on the base plate to communicate with other control modules, and the lighting module is fixed through the fixing bracket. Easy to install and more solid.

[0037] refer to Figure 1 to Figure 3 As shown, the fixed bracket includes a carrier sheet 11, a surrounding block sheet 12 and a foot 13; the carrier sheet 11 is...

Abstract

The invention provides a lighting module of barcode recognition equipment. The lighting module comprises a lighting source, a condensing lens, a camera shooting module, a fixed support and a bottom plate; the fixed support is used for fixing the lighting source, the condensing lens and the camera shooting module on the bottom plate; the condensing lens comprises two structural assembly blocks and an effective mirror plane, the two structural assembly blocks are arranged side by side at a certain interval, and the effective mirror plane is erected at the tops of the two structural assembly blocks, so that the structural assembly blocks and the effective mirror plane form a containing space; and the lighting source is arranged in the containing space, and light rays of the lighting source penetrate through the condensing lens to supplement light for the image recognition zone of the camera shooting module. The condensing lens, the lighting source and the camera shooting module are combined to form a whole body by the fixed support, so that the lighting source, the condensing lens and the camera shooting module can be firmly fixed, thus being uneasy to cause dislocation and displacement, being convenient to install and fix, saving installing and operating time, and greatly improving working efficiency.

Description

technical field [0001] The invention relates to the automatic identification industry, in particular to a lighting module of a barcode reading device. Background technique [0002] Barcode decoding equipment or image recognition equipment in the prior art is poor in indicating and supplementary lighting devices. [0003] In terms of indicating lighting devices, LEDs with small divergence angles that have not been involved in secondary optics are used as indicating lighting sources, and the divergence angle is generally 10-15 degrees; The divergence angle is generally 10-15 degrees. LEDs generally have a dome cover, and the light converges under the action of the dome cover. However, due to the material and design of the dome cover, the light is emitted after refraction and reflection. Even, it is easy to form a ring-shaped bright band, and the divergence angle is still too large for barcode reading applications. When it is applied to long-distance barcode decoding, as the l...
