Abstract

The invention relates to the field of sensor manufacturing, and discloses a manufacturing equipment and manufacturing method of an oxygen sensor seat assembly. The equipment comprises a mounting table and an annular conveying belt, a feeding mechanical arm, a first press-fit device, a second press-fit device, a third press-fit device, a laser welding device, an eddy current detection device, a laser coding device, a code scanning device and a discharging mechanical arm are sequentially arranged in the conveying direction of the annular conveying belt, and the devices arranged in the conveying direction of the annular conveying belt and the annular conveying belt are fixed to the mounting table and controlled through a control device. The method comprises the steps that 1, a base to be assembled is put into the conveying belt; 2, the base and other parts are subjected to press-fit assembling; 3, the assembly with press-fit welding completed is welded; 4, fusion depth detection is carried out on the welded assembly through eddy currents; 5, laser coding is carried out on the assembly passing appearance discrimination; 6, coding printing information is confirmed; and 7, the assembly with the code printing information confirmed to be correct is packaged.

Description

technical field [0001] The invention relates to the field of sensor manufacturing, in particular to a manufacturing device for an oxygen sensor seat assembly and a manufacturing method for the oxygen sensor seat assembly. Background technique [0002] From the perspective of assembly structure, the oxygen sensor seat assembly is generally composed of a base, 1-3 layers of protective sleeves, and compensation gaskets. Main process schemes: press fit, laser welding, laser coding, code scanning, visual inspection, packaging and storage; the main function is to prevent the solid matter in the exhaust gas from directly affecting the installed sensor components. Oxygen sensors need to withstand high temperature, strong pressure pulsation and high vibration load during operation, and have high requirements for welding strength. Traditional techniques cannot provide a reliable and economical detection solution, resulting in defective products flowing into the market. Contents of ...
