Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, 2 and 3, the scanner provided by the present invention includes a scanner body (not shown) and a CCD scanning assembly 1 disposed in the scanner body. The CCD scanning assembly 1 includes an LED module 11, a CCD module 12 and a processing chip 13, which are all integrated on a circuit board (not shown), and the CCD scanning assembly 1 controls and processes data of the LED module 11 and the CCD module 12 through the processing chip 13, so that the scanner has a more compact overall structure, a lower cost and a better performance.
The LED module 11 includes an LED lamp 111, a grating sheet 112 and a lens 113, which are sequentially disposed, and is mainly used for emitting a scanning beam to irradiate the barcode 2. Specifically, the LED lamp 111 may be a red LED lamp, which is mainly used for emitting a scanning light source. The grating sheet 112 is disposed in front of the LED lamp 111, and is mainly used for filtering the scanning light source passing through the grating sheet 112 into a scanning beam in a stripe shape. The lens 113 is disposed in front of the grating sheet 112, and is mainly used for expanding the scanning range of the scanning beam.
The CCD module 12 includes a cat-eye lens barrel 121 and a CCD module 122, and is mainly used for receiving light reflected by the barcode 2 to perform image formation. Specifically, the cat-eye lens barrel 121 is disposed in front of the CCD module 122, and mainly uses the principle of pinhole imaging to reflect the light reflected by the barcode 2 to the CCD module 122 again. The CCD module 122 is a charge coupled device that converts an optical signal reflected thereto into an electrical signal mainly using the photoelectric coupling principle. In addition, the center line of the LED module 11 and the center line of the CCD module 12 are arranged in parallel in order to maximize the overlap between the scanning range of the LED module 11 and the imaging range of the CCD module 12.
As shown in fig. 3, the LED module 11 and the CCD module 12 are both connected to a processing chip 13, which is mainly used for driving the LED module 11 and the CCD module 12, and decoding and processing data of the image formed by the CCD module 12. The processing chip 13 includes a graph acquisition and comparison module 131, a brightness control module 132 and an application processing module 133.
The image acquisition and comparison module 131 is connected to the CCD module 12, and is mainly used for acquiring an image imaged by the CCD module 12 and analyzing a gray scale of the image to generate a gray scale signal. The brightness control module 132 is connected to the LED module 11 and is mainly configured to receive the gray scale signal sent by the image collecting and comparing module 131 and send a control signal according to the gray scale signal to control the LED module 11, so as to adjust the brightness of the scanning beam. Specifically, the brightness control module 132 controls the brightness of the scanning beam by adjusting the magnitude of the current input to the LED module 11. When the gray scale signal generated by the image acquisition and comparison module 131 is increased (i.e. the brightness of the scanning beam is larger), the current input of the LED module 11 is reduced; when the gray scale signal generated by the image capturing and comparing module 131 is decreased (i.e. the brightness of the scanning beam is smaller), the current input of the LED module 11 is increased.
The application processing module 133 is connected to the LED module 11 and the CCD module 12, and is mainly used for analyzing and processing data before and after decoding, so as to improve the performance of the scanner. In some embodiments, the application processing module 133 may be used to analyze and process the imaged graphics before decoding. For example: when the image imaged by the CCD module 12 is not clear, the application processing module 133 may be used to improve the definition of the imaged image, thereby improving the success rate of decoding. The application processing module 133 may also be configured to analyze and process the decoded scan data, and transmit the scan data to a host (not shown) via bluetooth (not shown). For example: when the electrical signal generated after the CCD module 12 is decoded is weak, the application processing module 133 may be used to enhance the electrical signal, thereby further improving the success rate of decoding.
The invention also provides a wearable scanner (not shown) which comprises a wearing component (not shown) and a scanner connected with the wearing component. By using the scanner, the whole structure of the wearable scanner is more compact, the cost is lower, and the performance is better. The wearable scanner may be a ring, a watch, glasses, or other wearable scanner using the scanner, and is not limited herein.
In summary, the present invention provides a scanner, which includes a scanner body and a CCD scanning assembly 1 disposed in the scanner body, wherein the CCD scanning assembly 1 includes an LED module 11, a CCD module 12 and a processing chip 13, all integrated on a circuit board. The scanner controls and processes data of the LED module 11 and the CCD module 12 through the processing chip 13, so that the whole structure of the scanner is more compact, the cost is lower, and the performance is better.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
