AI Technical Summary
In the current electricity meter testing process, the circuit board is inconvenient to install and remove, resulting in low operating efficiency and easy damage.
A fixed fixture for testing electricity meters was designed, comprising a lifting component, a positioning component, and an ejection component, to achieve automated linkage between testing and ejection actions. The lifting component drives the testing board to move synchronously with the ejection component, avoiding direct contact with the circuit board.
This improved the efficiency of circuit board retrieval, reduced the risk of circuit board damage, and ensured the stability and safety of the testing process.
