Description

Technical Field

[0001] The present invention belongs to the technical field of printers, and in particular relates to a printer capable of automatically and accurately identifying RFID bar codes. Background Art

[0002] A printer is an electronic device used to convert data from a computer or other digital device into visible text or images, usually output on paper. Printers are one of the common office automation devices in offices and homes, used to print documents, reports, pictures, etc.

[0003] Traditional RFID printers have the following main disadvantages.

[0004] First, the cost is high; RFID printers are usually more expensive than traditional barcode printers, mainly because they integrate complex RFID radio frequency modules (including transmitters and receivers), control units, reader antennas and other components. These components increase production costs, making the price of RFID printers higher. The installation structure design of traditional RFID components is complex, which also makes the overall price of the printer high.

[0005] Second, it is sensitive to the use environment. Although RFID tags have better durability and anti-pollution ability than barcodes, in certain specific environments (such as near metal or liquid), RFID signals may be interfered with, resulting in reading failure or data errors. This limits the application of RFID printers in specific scenarios to a certain extent, and also causes unstable signals, affecting printing effects and accuracy.

[0006] In this regard, we propose a new printer that can automatically and accurately identify RFID to address the shortcomings of existing technologies. Summary of the invention

[0007] The purpose of the present invention is to provide a printer that can automatically and accurately identify RFID barcodes to solve the problems raised in the above background technology.

The RFID component is configured to generate a data receiving area, and the top horizontal surface of the generated data receiving area is in contact with the lower surface of the front paper stop cover, and the distance between the front paper stop cover and the vertical cutting plane at the front end of the rubber roller is between 2-2.5mm.

[0009] A further implementation of the present invention is that the RFID component includes an RFID transmitter and an RFID receiver, the RFID transmitter is connected and installed inside the front end of the front paper stop cover, the RFID receiver is connected and arranged inside the upper end of the front paper stop cover, and the RFID receiver is located above the RFID transmitter and can realize data transmission configuration.

[0010] A further implementation scheme of the present invention is that the front paper stopper cover includes a positioning frame formed at the rear thereof, the positioning frame is a rectangular frame structure, a clamping column is also protruded from the rear of the front paper stopper cover, and the RFID receiver is fixedly clamped on the clamping column and the top inner wall of the positioning frame.

[0011] A further embodiment of the present invention is that it also includes a heat dissipation aluminum block and heat dissipation silicone grease, the RFID transmitter is locked and fixed inside the front paper stop cover together with the heat dissipation aluminum block by screws, and the heat dissipation silicone grease is arranged between the RFID transmitter and the heat dissipation aluminum block.

In the process of the RFID transmitter transmitting the signal data to the RFID receiver, the signal data is reflected by the signal data enhancement space and the label data is visually configured to the rubber roller.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] It should be noted that, in the description of the present application, the orientation or positional relationship indicated by terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0024] It should be noted that, in the present application, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises one..." does not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be noted that the scope of the method and device in the embodiment of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0025] During the processing of the existing printer flatbed accessories, it is necessary to clamp them and then process the surrounding edges. Although the currently used negative pressure suction cup can pre-tighten the flatbed accessories, it is also necessary to continuously spray water on the flatbed accessories to cool them down during the processing, and to blow air to blow away debris. Therefore, the clamping force is insufficient simply from the normal pre-tightening force of one side of the flatbed accessories, and there is a high probability of clamping failure. In addition, when the edge of the flatbed accessories needs to be chamfered, the angle of the tool must be changed to achieve the processing process because the angle of the flatbed accessories cannot be changed, which has great limitations.
