Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described by the following detailed description with reference to the accompanying drawings.
In the description of the present invention, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
As shown in 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 comprises 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 on 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.
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 to emit 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 strip-shaped scanning light beam. The lens 113 is disposed in front of the grating sheet 112, and is mainly used to expand the scanning range of the scanning beam.
The CCD module 12 includes a cat eye lens barrel 121 and a CCD module 122, which is mainly used for receiving the light reflected on the bar code 2 for imaging the pattern. Specifically, the cat eye lens barrel 121 is disposed in front of the CCD module 122, and reflects the light reflected on the barcode 2 to the CCD module 122 mainly by using the principle of aperture imaging. The CCD module 122 is a charge-coupled device, which mainly uses the principle of photo-coupling to convert the optical signals reflected thereon into electrical signals. In addition, in order to overlap the scanning range formed by the LED module 11 and the imaging range formed by the CCD module 12 to the maximum extent, the center line of the LED module 11 and the center line of the CCD module 12 are arranged in parallel.
As shown in fig. 3, the LED module 11 and the CCD module 12 are connected to a processing chip 13, which is mainly used for driving the LED module 11 and the CCD module 12, and decoding and data processing the image imaged by the CCD module 12. The processing chip 13 includes a graphics acquisition and comparison module 131, a brightness control module 132, and an application processing module 133.
The pattern acquisition and comparison module 131 is connected with the CCD module 12, and is mainly used for acquiring the patterns imaged by the CCD module 12 and analyzing the gray scales of the patterns to generate gray scale signals. 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 pattern acquisition and comparison 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 pattern acquisition and comparison module 131 increases (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 pattern acquisition contrast module 131 decreases (i.e. the brightness of the scanned 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 the 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 imaging pattern prior to decoding. For example: when the image formed by the CCD module 12 is unclear, the application processing module 133 may be used to improve the definition of the image formed, thereby improving the decoding success rate. The application processing module 133 may also be used to analyze and process the decoded scan data and send the scan data to a host (not shown) via bluetooth (not shown). For example: when the electric signal generated after the decoding of the CCD module 12 is weak, the application processing module 133 may be used to enhance the electric signal, thereby further improving the success rate of decoding.
The invention also provides a wearable scanner (not shown), which comprises a wearable component (not shown) and a scanner connected with the wearable 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 wearable scanner such as a finger ring, a wristwatch, glasses, etc. using the scanner, without limitation.
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 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.
