Wuhan Songsheng Optoelectronics has obtained a patent for a temperature-controlled laser device that features real-time temperature detection and feedback.

      Wuhan Songsheng Optoelectronics Technology Co., Ltd. has obtained a patent titled notice No. CN222243154U. The application date is January 2024. Below is a detailed description of the patent:

Device Composition

     The shell features a storage cavity, and the side wall of this cavity is equipped with a corresponding component.

     A circuit board assembly consists of multiple board bodies arranged at specified vertical intervals, along with at least one double-row connector positioned at the corresponding intervals between the board bodies. Both the board bodies and the double-row connectors are housed within a storage cavity, with each double-row connector serving to electrically connect adjacent board bodies. Additionally, the assembly includes an infrared temperature measurement module and a feedback drive module. A portion of the infrared temperature measurement module is integrated into one of the board bodies, while a part of the feedback drive module is located on an adjacent board body.

     The first connecting piece is arranged in the accommodating cavity and includes the plate body mounting part and the side wall mounting part. The plate body mounting part is designed to securely attach each plate body, while the side wall mounting part connects to the corresponding component.

     Core Function

     The primary function of the device is to integrate its infrared temperature measurement module, which detects temperature changes in real time during laser welding, with the feedback drive module that transmits temperature data to adjust the parameters of the laser emission. This closed-loop control mechanism ensures temperature stability throughout the welding process, significantly reducing defects caused by excessively high or low temperatures. Traditional welding methods often depend on the operator's judgment and experience; however, Songsheng Photoelectric's new device enhances welding quality through technical advancements, minimizing the impact of human factors.

     Technological Advantages and Points of Innovation

     Real-time Temperature Detection and Feedback: The infrared temperature measurement module detects temperature changes in real time during laser welding. The feedback drive module transmits this temperature information back to the laser drive, which then adjusts the laser emission parameters. This creates a closed-loop control mechanism that ensures temperature stability throughout the welding process. As a result, it significantly reduces welding defects caused by excessively high or low temperatures, thereby enhancing welding quality and accuracy.

     Circuit board components are designed for easy expansion and upgrades. Multiple boards are arranged at intervals along both the upper and lower sections and are electrically connected by double rows of pins. This compact structure allows for the straightforward addition or modification of functional modules, enabling flexibility to meet various application requirements.
