This application relates to the field of battery coolant production technology, specifically a sampling and extraction device for the production of renewable and biodegradable green battery coolant. The device includes a frame mounted on a testing platform and a liquid delivery device fixed to the frame. A sampling and extraction module is also provided on the testing platform, comprising a testing tube, testing equipment, and a gas delivery device. This sampling and extraction device for renewable and biodegradable green battery coolant production utilizes a oscillation motion during movement to gently agitate the coolant, breaking up static stratification and sedimentation, improving sample representativeness, and ensuring that the test results accurately reflect the quality of the entire batch of products. Simultaneously, the linkage between the oscillation and the heated, enclosed environment allows heating to reduce viscosity, making homogenization easier. The oscillation accelerates heat diffusion, resulting in more uniform temperature, while the enclosed environment prevents heat and component loss, achieving uniform temperature, uniform composition, and stable state, significantly improving the accuracy, repeatability, and reliability of sampling and testing.

The utility model discloses a kind of CSP lamp bead packaging structures of embedded coplanar welding.The packaging structure includes metal substrate and LED chip with first, second electrode.The core is, metal substrate and electrode have mutually adapted three-dimensional geometry configuration, and they form docking structure, so that electrode bottom surface and metal substrate bottom surface jointly form a wide coplanar welding plane.The utility model realizes the self-alignment and pre-welding mechanical locking of chip by three-dimensional docking structure, solves the existing tiny CSP chip mounting difficulty, the problem of low yield;And through the coplanar welding plane formed, fundamentally solve the problem of insufficient welding area, poor reliability, while optimizing heat dissipation performance.
