The invention provides a pressure self-adaptive device for precise ultrasonic welding of POCT chip products, including a fixture body, an elastic body and a bottom plate, the fixture body and the elastic body are installed on the bottom plate, and the elastic body is installed between the fixture body and the bottom plate, And in contact with the fixture body and base plate. The fixture body also includes a positioning and clamping mechanism for the POCT chip. The invention realizes the self-adaptive adjustment of the parallelism and pressure of the POCT chip to be welded and the welding head through the elastic deformation of the elastic body, and ensures the parallelism and uniform pressure of the welding head and the POCT chip during the welding process; The bolt realizes the positioning and clamping of the POCT chip, and can adapt to the positioning requirements of chips of different sizes by adjusting the position of the top column and the pressure plate, and maintains the relative position between the POCT chip and the welding head during the welding process. The invention has the advantages of simple and compact structure, high adaptability, high welding precision, convenient adjustment, wide applicability, low cost, etc., and can effectively improve production efficiency.
Description
technical field [0001] The invention relates to a pressure adaptive device for ultrasonic precision welding of medical POCT chip products, and belongs to the technical field of manufacturing medical polymer POCT chip products. Background technique [0002] POCT (Point of Care Testing) point-of-care testing is a new technology for the development of laboratory medicine. It emerged at the annual meeting of the American Association of Clinical Chemistry (AACC) in 1995. POCT point-of-care testing refers to a rapid testing technology that is performed close to the patient's bedside, and the test can also be performed outside the hospital bed, ward or traditional central laboratory. Compared with the traditional central laboratory testing process, POCT has the characteristics of simple operation, less sample consumption, whole blood samples, short turn around time (TAT) and instant result reporting. The diagnosis and treatment of clinically acute patients provide favorable condit...
