[0002] In the production process of aluminum electrolytic capacitors, charge and discharge testing is a crucial step. This testing is typically done manually, often requiring workers to manually align the capacitor's interfaces with the detector before testing. This method suffers from low efficiency and poor reliability.

[0003] Since inefficient manual inspection cannot meet the charging and discharging testing tasks in the mass production of capacitors, a ring-shaped stepping conveyor was designed to hold the capacitors and automatically feed them one by one into the charging and discharging testing device for testing. The specific operation process is as follows: first, the aluminum electrolytic capacitors are fed into the ring-shaped stepping conveyor by the vibrating plate and feed channel of the feeding machine, and then by the robotic arm. According to the stepping rhythm of the ring-shaped stepping conveyor, the aluminum electrolytic capacitors are fed into the charging and discharging testing device one by one for charging and discharging testing. After the testing is completed, the ring-shaped stepping conveyor classifies and releases the capacitors according to the test results.

[0004] Existing ring-shaped stepping conveyor devices require individual clamping, step-by-step transport, and release of capacitors as needed. The overall structure is complex, with a high failure rate and high cost.
