Description

Technical Field

[0001] The present invention relates to the technical field of ignition coil manufacturing, in particular to a device for detecting and judging primary inductance static parameters and secondary resistance parameters of an ignition coil. Background Art

[0002] The ignition coil is one of the important components of a gasoline engine. Whether the static parameters of the primary inductance and the secondary resistance of the ignition coil meet the technical requirements will directly affect the performance of the ignition coil, causing the engine to malfunction or even fail to work after being installed on the vehicle engine. Therefore, during the ignition coil manufacturing process, how to detect whether the ignition coil meets the relevant technical requirements has become an important link in ensuring that the ignition coil can work properly when installed on the vehicle engine.

[0003] Currently, during the ignition coil production process, measurements of primary inductance static parameters and secondary resistance parameters are typically performed using an LCR digital bridge to measure the primary inductance and a multimeter to measure the secondary resistance parameters. This requires two sets of variables to be measured. Existing measurement equipment and methods inevitably require testing on both sides, increasing the workload of on-site workers and reducing production efficiency. Furthermore, the complex structure of the device makes it difficult to accurately determine the ignition coil's placement during measurement, making operation extremely inconvenient.
