When the device is used, a mark to be detected of a product, namely a mark on a bottle cap or a bottle cap cover of a wine bottle, faces towards the rear side of the light shield 1, is placed into the light shield 1 from the lower side of the light shield 1, when the product is detected by the sensor to be positioned 4, a starting signal is triggered to the light emitting source 2 and the camera 3, the light emitting source 2 and the camera 3 are started simultaneously, the acquisition of a mark image is completed, and the acquired image is sent to the background for processing, information acquisition, storage and the like. The device replaces manual input by image acquisition identification information, and is time-saving and labor-saving. In addition, the placement of the product (namely the wine bottle) can be completed manually or by an intelligent mechanical mechanism, such as a manipulator or other displacement mechanisms, so that the product is taken and placed without or only by manually participating in a small amount of operation, and the labor cost is saved. In addition, the image acquisition identification mode can be suitable for various types of identifications, and the applicability is wider.

Specifically, the light shield 1 is preferably in a vertical circular tube shape, and the cylindrical inner wall can reflect light rays at multiple angles, so that the brightness in the light shield 1 is softer, and strong reflection or high exposure on a mark is avoided, and the definition of a photo acquired by the camera 3 is influenced.

In order to more conveniently take and put products in the light shield 1, a door opening-shaped opening 13 is formed in the front side of the light shield 1, the amplitude of up-and-down motion when taking and putting products is reduced, particularly for some products with higher heights, the time for taking and putting the products is saved, and the operation efficiency is improved.

The light source 2 is installed above the upper port of the light shield 1, and preferably comprises two light sources, which are symmetrically arranged relative to the vertical plane of the connecting line between the photographing opening 11 and the center of the light shield 1, so as to provide sufficient illumination and make the illumination as uniform as possible.

Specifically, the two light emitting sources 2 are horizontal bar-shaped light sources and are arranged in a V shape, the approaching ends of the two light emitting sources are close to the photographing opening 11, the two light emitting sources 2 project light downwards in an inclined mode towards the opposite sides of the two light emitting sources, the light is projected to the positions close to the two sides of the photographing opening 11, the light is mainly concentrated in the half area where the mark corresponds, the light emitting sources 2 are effectively utilized, and the power of the light emitting sources 2 can be reduced when sufficient illumination is obtained.

According to the application, the light is not directly projected towards the shooting port 11 or the position where the marker is located by adopting the light-emitting source 2, so that the light is directly projected towards the shooting port 11, and then the light is directly acquired by the camera 3 through the shooting port 11, so that the contrast brightness of the marker is reduced in the picture acquired by the camera 3, the definition of the marker is affected, and the reflection effect of the side wall of the light shield 1 is not ideal because the shooting port 11 occupies a part of the area and projects the light towards the direction. The direct projection of light to the mark can make the mark exposed too strongly or reflected light locally strongly, which affects the camera 3 to obtain a clear image of the mark.

Whereas the two light sources 2 of the V-shaped arrangement of the present application are capable of illuminating as far as possible the half area where the reflected light is located. However, through the actual measurement, because two luminous sources 2 own have certain volume, therefore the illumination intensity at the two butt joint positions can reduce, forms the darker region of luminance, and for this reason, sign information acquisition device still includes transparent light plate 5, is located on the shooting route of shooting mouth 11 and camera 3, and transparent light plate 5 is equipped with the light filling lamp 6 that shines from its edge to the center all around, through the light filling of transparent light plate 5, can improve the luminance of camera 3 acquisition sign region, avoids appearing darker region in the image, influences the definition of image.

Through practical tests, the transparent light plate 5 can reinforce the brightness of the darker areas of the mark so that the brightness of the darker areas is almost equal to the brightness of the areas on two sides.

In this embodiment, the combination of the transparent light plate 5 and the light compensating lamp 6, and the two light sources 2 are preferably installed in a position-adjustable manner, so as to debug the light source before use to obtain the best shooting effect. The two light sources 2 are preferably horizontally positioned and angularly submittable, and the combination of the transparent light plate 5 and the light supplement lamp 6 is preferably vertically and horizontally positioned adjustable.

Preferably, the positioning sensor 4 is a lifting mechanism, and the lifting mechanism is used for lifting the product to enter the light shield 1, but the application is not limited thereto, and the identification information acquisition device can also be used when the positioning sensor is manually placed, and the positioning sensor 4 will be described below by taking the lifting mechanism as an example of the matching object.

The positioning sensor 4 preferably comprises two, vertically arranged, in this embodiment the positioning sensor 4 is preferably a photoelectric sensor.

The positioning sensor 4 located below is used for detecting the height position of a product, when the lifting mechanism lifts the product from the lower side of the light shield 1 to be detected by the positioning sensor 4 located below, the mark just corresponds to the shooting port 11, and meanwhile, the positioning sensor 4 triggers a starting signal to the light emitting source 2 and the camera 3, so that image shooting of the mark is completed.

The positioning sensor 4 located above is used for abnormality protection detection, and is externally connected with a warning device (not shown in the figure), when the positioning sensor 4 detects a product, the positioning sensor indicates that the product is too high in placement height, and a trigger signal gives a warning signal to the warning device. When the lifting mechanism is matched, the positioning sensor 4 is also in communication connection with the lifting mechanism, and sends a signal to the warning device and simultaneously to the lifting mechanism, so that the lifting mechanism stops moving and collision with the light shield 1 is avoided.

In addition, in the present embodiment, the included angles between the connecting lines between the positions of the detecting hole 12 and the photographing opening 11 and the center of the light shielding cover 1 are preferably 90 degrees, so as to avoid the light of the positioning sensor 4 from affecting the image obtained by the camera 3.
