Description

Technical Field

[0001] This utility model relates to the field of QR code technology for data collectors, specifically a QR code labeling and affixing device for data collectors based on backlight illumination. Background Technology

[0002] The QR code on the collector of energy storage equipment is an important medium for equipment information management, data interaction and operation and maintenance management. Its core function is to enable rapid identification, information query and function linkage of energy storage equipment by scanning the code. However, the existing QR code labels for data collectors still have the following technical problems when used: 1. Poor environmental adaptability: QR codes are difficult to recognize accurately in low-light environments (basements, nighttime, inside equipment cabinets); metal surfaces are prone to glare, affecting the scanning effect; 2. Inconvenient to operate: Requires additional lighting equipment, making it inconvenient to operate with both hands; difficult to quickly locate the QR code in dim environments; 3. Durability issues: Self-adhesive labels are prone to falling off in high temperature, humidity, and vibration environments; surface printing is easily blurred due to friction and corrosion; replacement costs are high when equipment information changes. 4. Functional limitations: Traditional signs lack active lighting and rely entirely on external light sources; they only provide static information and cannot display device status; they lack intelligent interactive capabilities. 5. Complex maintenance: Installation location is limited, only suitable for flat surfaces; maintenance costs are high after the markings are damaged; manual pasting results in poor quality consistency.

[0003] To address this issue, a backlit QR code labeling device for data collectors is proposed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0015] Example: Please see Figure 1-3 This utility model provides a technical solution: A QR code labeling device for a backlit data collector includes an adhesive base 1. An acrylic adhesive layer 2 is fixed to the back of the adhesive base 1. During installation, it is necessary to ensure that the acrylic adhesive layer 2 is completely adhered to prevent air residue from affecting the adhesion strength. An air vent is designed at the bottom to ensure a firm adhesion. A power supply battery 3 is fixed inside the adhesive base 1, supporting long-term maintenance-free operation. A control circuit board 4 is fixed to the front of the power supply battery 3. A QR code carrier layer 5 is fixed to the front of the adhesive base 1. The QR code carrier layer 5 has a size of 30×30mm. The QR code pattern on the QR code carrier layer 5 is made by laser engraving or thermal transfer process to ensure long-term clarity. LED beads 6 are fixed around the QR code carrier layer 5 on the front of the adhesive base 1. The high-brightness LED beads 6 arranged in a ring provide uniform backlight illumination. A transparent protective layer 7 is fixed outside the QR code carrier layer 5 and LED beads 6 on the front of the adhesive base 1. The transparent protective layer 7 is made of high light transmittance PC material and has an anti-glare treatment to protect the internal structure from external damage.

[0016] The control circuit board 4 includes an integrated light sensor, a trigger switch, and a brightness adjustment circuit to achieve intelligent lighting control.

[0017] Intelligent control logic: Ambient light <50Lux → automatically turn on backlight with adaptive brightness; detect proximity <10cm → force backlight to 50% brightness; no operation for 5 seconds → automatically turn off and enter standby mode; battery <10% → low power mode, emergency lighting only.

[0018] A protective layer 8 is attached to the back side of the acrylic adhesive layer 2.

[0019] A graphite heat-absorbing layer 9 is fixed to the inner wall of the adhesive base 1 to keep its working temperature <60°C. The graphite heat-absorbing layer 9 is made of a material with high thermal conductivity (≥1500 W / m·K).

[0020] There are 12 LED beads in total.

[0021] Working principle: 1. Installation stage: Peel off the protective layer 8 on the back of the acrylic adhesive layer 2, attach the device to the designated position of the energy storage equipment, and turn on the trigger switch of the device; 2. Standby mode: The device is in low-power standby mode, and the light sensor continuously monitors the ambient light. 3. Automatic triggering: When insufficient ambient light is detected or a barcode scanning device is nearby, the LED beads 6 will automatically light up; 4. Illumination: LED beads 6 illuminate the QR code carrier layer 5 area to ensure that the scanning device can clearly recognize the pattern; 5. Intelligent adjustment: The LED beads 6 automatically adjust the backlight brightness according to the ambient light through the operation of the light sensor, optimizing the recognition effect and saving energy; 6. Automatic shutdown: After scanning is completed or after a certain period of inactivity, the backlight will automatically turn off and enter standby mode.

[0022] This solution solves the problem of recognizing traditional QR code labels in low-light environments, and enables maintenance-free, intelligent equipment label management.
