Description

[Technical Field]

[0001] This utility model relates to the field of printers, and in particular to a portable printer. [Background Technology]

[0002] Currently, portable printers, as small item management label printing machines with increasingly widespread use in commercial and home scenarios, have been integrated into all aspects of daily item classification and management. Consequently, the quality requirements for printer products themselves are becoming increasingly stringent, such as stricter requirements for product production costs and structural optimization. However, in the RFID antenna design of existing printer products, a separate installation space needs to be allocated for the RFID antenna, such as setting a position on the paper tray shell for installing the RFID antenna. After installation, the RFID antenna also needs to be reinforced with tape. In addition, the RFID antenna needs to be soldered to the circuit board through soldering points, and then the power supply needs to be placed on the circuit board. This will increase production costs and product size, as well as increase the complexity of the assembly process.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. [Utility Model Content]

[0004] The technical problem that this utility model needs to solve is:

[0005] In the design of RFID antennas for existing printer products, a separate installation space is required for the RFID antenna. A position for installing the RFID antenna needs to be set on the paper tray housing. After installation, the RFID antenna needs to be reinforced with tape. In addition, the RFID antenna needs to be soldered to the circuit board through soldering points, and then the power supply needs to be placed on the circuit board. This will increase production costs and product size, as well as increase the complexity of the assembly process.

[0006] This utility model achieves the above objectives through the following technical solution:

[0007] This invention provides a portable printer, including a housing, a paper tray, and a PCB board;

[0008] Both the paper tray and the PCB board are housed within the casing.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The portable printer provided in this embodiment of the utility model includes a housing, a paper tray, and a PCB board;

[0023] Both the paper tray and the PCB board are housed within the casing. The PCB board is printed with an RFID antenna, which communicates with electronic tags on the label paper placed in the paper tray.

Detailed Implementation Methods

[0029] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0030] Example 1:

[0031] This embodiment provides a portable printer, such as Figure 1-3 As shown, it includes a housing 1, a paper tray 2, and a PCB board 3;

[0032] Both the paper tray 2 and the PCB board 3 are disposed inside the housing 1;

[0033] The PCB board 3 is printed with an RFID antenna 33, which is used to communicate with the electronic tags on the label paper placed in the paper tray 2.

[0034] In this embodiment, the RFID antenna 33 is directly printed on the PCB board 3 during processing. When the worker attaches the PCB board 3 to the housing 1, the RFID antenna 33 can be directly coupled to the paper tray 2. This process eliminates the need to solder the RFID antenna 33 to the soldering point on the PCB board 3, and also eliminates the need to set up additional space for RFID installation on the paper tray 2. This greatly improves the worker's installation efficiency, further reduces production costs, and reduces the size of the product.

[0035] To ensure the accuracy and timeliness of communication between the electronic tag and the RFID antenna 33, preferably, the PCB board 3 is disposed inside the housing 1, specifically:

[0036] The PCB board 3 includes an electronic component board 31 and an antenna board 32;

[0037] The electrical component board 31 is coupled to the housing 1, and the antenna board 32 is coupled to the paper tray 2.

[0038] In this embodiment, to ensure the accuracy and timeliness of communication between the electronic tag and the RFID antenna 33, the PCB board 3 is designed as an L-shape and divided into two parts. One part of the PCB board 3 is an electrical component board 31, on which various electrical components are installed, and the electrical component board 31 is coupled to the housing 1. The other part of the PCB board 3 is an antenna board 32, on which the RFID antenna 33 is printed, and the antenna board 32 is coupled to the paper tray 2 to ensure the accuracy and timeliness of communication between the RFID antenna 33 printed on the antenna board 32 and the electronic tag.

[0039] Preferably, the antenna plate 32 is used to print the RFID antenna 33.

[0040] To ensure that the PCB board 3 is installed more accurately and securely within the housing 1, preferably, the paper tray 2 is provided with a mounting post 21, and the antenna board 32 is provided with a mounting hole 321 coupled to the mounting post 21. The mounting hole 321 can be elliptical, and the mounting post 21 can be cross-shaped.

[0041] Preferably, the electronic component board 31 is provided with an RFID chip 311, which is electrically connected to the printed RFID antenna 33 so that the RFID chip 311 can communicate with the electronic tags on the label paper placed in the paper tray 2 through the RFID antenna 33.

[0042] In a real-world scenario, one part of the PCB board 3 is an electrical component board 31, on which various electrical components are mounted, including an RFID chip 311; the other part of the PCB board 3 is an antenna board 32, on which the RFID antenna 33 is printed, and the RFID antenna 33 is electrically connected to the RFID chip 311 through various electronic components contained in the electrical components.

[0043] Preferably, the RFID antenna 33 is also used to communicate with a mobile terminal or a PC.

[0044] Preferably, the electronic tag includes a data storage area for storing a unique identification code on the tag paper.

[0045] In a real-world scenario, the RFID chip 311 controls the RFID antenna 33 to generate current, thereby creating a magnetic field around the RFID antenna 33. When the electronic tag senses the magnetic field generated by the RFID antenna 33, it also generates current, thus transmitting the unique identification code stored in the electronic tag to the RFID chip 311 through the RFID antenna 33.

[0046] The portable printer provided in this embodiment of the utility model includes a housing 1, a paper tray 2, and a PCB board 3;

[0047] Both the paper tray 2 and the PCB board 3 are housed within the housing 1. The PCB board 3 is printed with an RFID antenna 33, which communicates with the electronic tags on the label paper placed in the paper tray 2. This invention allows workers to directly install the RFID antenna onto the paper tray 2 while installing the PCB board 3 onto the housing 1, eliminating the need to install the RFID antenna 33 in the corresponding position on the paper tray 2, fix it with tape, and then solder it to the soldering point on the PCB board 3. This reduces the complexity of the assembly process. Furthermore, since there is no need to allocate additional space for the RFID coil, production costs and product size are further reduced.
