Description

Technical Field

[0001] The present invention relates to the field of terminals, and more specifically, to a jet-type high-speed oiling and testing device for PCB female terminals. Background Art

[0002] At present, the domestic PCB terminal oiling method is mostly immersion oiling, the oiling is uneven, and most of the inside of the terminal cannot be oiled. The existing jet oiling equipment abroad is slow, only 5 terminals per second, which seriously affects efficiency.

[0003] With the continuous growth of the automobile market, the demand for relay boxes is also increasing, and the demand and quality of PCB terminals are also getting higher and higher. If there is a deviation in the terminal positioning, the relative position of the nozzle and the terminal will change, which will lead to uneven oiling or omissions. At the same time, the surface roughness and contamination degree of terminals in different batches may be different, which will affect the formation of the oil film. Summary of the invention
