Description

Technical Field

[0001] The utility model relates to the technical field of bar code reading, in particular to a bar code aiming and supplementary light device for data acquisition terminal equipment. Background Art

[0002] A data acquisition terminal is a device that can collect and transmit various data information, including but not limited to temperature, humidity, pressure, light intensity, location, etc. When collecting data, the data acquisition terminal often needs to scan barcodes, QR codes and other graphics to obtain relevant information. In order to achieve good reading effects in various environments, barcode reading equipment is basically equipped with high-intensity fill lights so that the reading environment can be fully filled with light. However, this also brings some problems. For example, when the fill light is irradiated on a material that is easily reflective, the reflected light may enter the camera of the device, causing part of the collected image to be too bright and affecting the subsequent decoding operation.

[0003] In the prior art, for example, a Chinese patent with announcement number CN219066140U, entitled A barcode reading device with green laser indication, discloses a technical solution in which the light emitted by the fill light has a certain directionality after passing through a first optical light-transmitting device, and then irradiates the surface of an object, and the reflected light enters the camera through a second optical light-transmitting device. Since the polarization directions of the two optical light-transmitting devices are different, the light spot during imaging can be greatly reduced. However, since most data acquisition terminals need to be carried to the workplace, the barcodes to be scanned are handheld for information collection, and some barcodes are located too high or too low, so that the collection angle between the barcode and the camera is limited, when the fill light irradiates the surface of an object with a barcode, since the irradiation angle of the fill light cannot be changed, the light emitted by the fill light may be reflected by the object to the camera to form a reflection, thereby affecting the scanning of the barcode.
