Description

Technical Field

[0001] This utility model relates to the field of barcode reader technology, and in particular to a barcode reader that is easy to dissipate heat. Background Technology

[0002] Barcode readers are core devices for product tracking and traceability in industrial automation. They use optical scanning technology to quickly read data from barcodes, QR codes, or DPM codes, enabling data collection and automated control of production processes. Barcode readers are characterized by high adaptability, ultra-high-speed processing capabilities, high stability, accurate reading, and the ability to combine multiple hardware components, making them widely used in smart manufacturing, logistics sorting, and quality traceability.

[0003] Industrial barcode readers are typically installed on or inside equipment. In high-temperature, high-frequency industrial applications, prolonged continuous use and external environmental factors can easily lead to overheating, causing chip malfunctions or exceeding design specifications for electronic components, resulting in reader failure and impacting field operations. Furthermore, with increasing data processing capabilities and higher specifications for the main chip, the internal chip of industrial barcode readers has become a major source of internal heat. Therefore, to ensure the normal operation of the barcode reader and its main chip and reduce the impact of temperature, timely cooling is necessary during actual use to maintain normal operation and ensure accurate and high-speed barcode reading. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a code reader that facilitates heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A barcode reader with easy heat dissipation includes an upper housing and a lower housing. After the upper and lower housings are fixed together, their interiors form an installation space for barcode reader components. A lens module and a main circuit board are installed inside the upper housing, with the main circuit board mounted adjacent to the upper housing. An input terminal and an output terminal extend from the inside of the housing to the outside. A main chip is provided on the main circuit board, and a miniature fan is provided adjacent to the main chip. A heat dissipation hole is provided on the top of the upper housing, corresponding to the position of the miniature fan. A waterproof and breathable membrane is provided on the inner side of the upper housing, corresponding to the position of the heat dissipation hole, and the area of ​​the waterproof and breathable membrane at least covers the heat dissipation hole.

[0007] Preferably, the miniature fan is directly mounted on the main circuit board, and the miniature fan is connected to the plug on the main circuit board via the FPC, and the main circuit board supplies power to the miniature fan.

[0008] Preferably, the micro fan is located directly below the heat dissipation hole.

[0009] Preferably, the waterproof and breathable membrane is installed on the inside of the heat dissipation holes using adhesive backing or fixing screws.

[0010] Preferably, the outer diameter of the fan does not exceed 20 mm.

[0011] More preferably, the outer diameter of the fan is 14-16 mm.

[0012] Preferably, the main chip is mounted on the side of the main circuit board facing the upper housing.

[0013] Preferably, the upper housing is a metal housing, and a heat-conducting component is attached to the main chip, with the top surface of the heat-conducting component abutting against the upper housing.

[0014] Preferably, the upper and lower shells are generally hollow triangular prisms.

[0015] The beneficial effects of this utility model are that the heat-dissipating barcode reader integrates a micro fan as a heat dissipation component inside the barcode reader, which can effectively dissipate heat inside the barcode reader and at the same time dissipate heat from the main chip inside the barcode reader that generates a lot of heat, thereby achieving the purpose of cooling down the barcode reader, maintaining the normal operation of the barcode reader, and extending the service life of the barcode reader. It is particularly suitable for the field of industrial barcode readers. Attached Figure Description

[0020] To provide a better understanding of the purpose, structure, features and functions of this utility model, detailed descriptions are provided below with reference to the embodiments.

[0021] like Figure 1The illustrated barcode reader includes an upper housing 10 and a lower housing 20. The upper and lower housings are fixed together, forming an internal space for mounting the reader components. A lens module 31 and a main circuit board 30 are installed within the inner housing, with the main circuit board 30 mounted adjacent to the upper housing 10. An input terminal 11 and an output terminal 12 extend from the inside of the housing to the outside. A main chip 32 is mounted on the main circuit board 30, and a miniature fan 34 is positioned adjacent to the main chip 32. A heat dissipation hole 101 is located on the top of the upper housing 10, corresponding to the blade position of the miniature fan 34. A waterproof and breathable membrane (not shown) is located on the inner side of the upper housing 10, corresponding to the heat dissipation hole 101, with the area of ​​the waterproof and breathable membrane at least covering the heat dissipation hole 101.

[0022] In a preferred embodiment, see Figure 2 The micro fan 34 is directly mounted on the main circuit board 30. The micro fan is connected to the plug on the main circuit board 30 through the FPC (flexible circuit board) 36, and the main circuit board 30 supplies power to the micro fan.

[0023] See Figure 3 In a preferred embodiment, the micro fan 34 is located directly below the heat dissipation hole 34, that is, the structural center of the micro fan 34 is roughly aligned with the structural center of the geometric shape formed by the heat dissipation hole 34; in this way, the heat dissipation efficiency can be improved.

[0024] The waterproof and breathable membrane is sized to at least cover the heat dissipation holes 101. It can be installed inside the heat dissipation holes by adhesive backing or fixing screws to prevent moisture or other micro-impurities from entering the reader and affecting its normal operation.

[0025] In a preferred embodiment, the outer diameter of the fan does not exceed 20 mm, and more preferably, the outer diameter of the fan is 14-16 mm.

[0026] In another preferred embodiment, the upper housing 10 is a metal housing, and the main chip 32 is mounted on the main circuit board 30 on the side facing the upper housing 10. More preferably, a heat-conducting component, such as thermally conductive rubber or thermally conductive foam, is attached to the main chip 32, with the top surface of the heat-conducting component abutting against the upper housing 10. This not only prevents damage to the main chip 32 but also allows the heat from the main chip to be dissipated outwards through the metal housing via the heat-conducting component, further improving the heat dissipation efficiency of the barcode reader.

[0027] In another preferred embodiment, the upper housing 10 and the lower housing 20 are generally hollow triangular prisms. This provides better assembly space when installing the internal components of the barcode reader into the housing, facilitating product assembly.

[0028] It should be understood that the upper and lower shells in the above embodiments are only for the purpose of illustrating the structure of this utility model, and are not intended to limit the installation orientation of the barcode reader or its actual setting position during use.

[0029] This utility model discloses a barcode reader with convenient heat dissipation. It integrates a miniature fan as a heat dissipation component, effectively cooling the internal components of the barcode reader and promptly dissipating heat from the main chip, which generates significant heat. This cooling effect helps maintain the normal operation of the barcode reader. The integrated miniature fan is directly mounted on the PCB board, adjacent to the main chip, without affecting the size of the barcode reader, while ensuring the normal operation of the miniature fan and effective heat dissipation for the main chip. A waterproof and breathable membrane ensures airflow while preventing moisture or debris from entering the barcode reader and causing damage. This utility model is particularly suitable for the industrial barcode reader field, eliminating the need for a dedicated heat dissipation device on or inside the equipment.

[0030] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
