The
lithium battery cap
assembly machine comprises a main
machine frame, an index plate, an anti-explosion piece feeding device, a top cover feeding device, a
welding device, an edge covering device, a conveying mechanical arm, a shaping device, a
rubber ring feeding device and an
internal resistance measuring device, and the index plate is installed on the main
machine frame; a plurality of sets of jigs arranged around the center axis of the index plate in the circumferential direction are installed in the index plate, the anti-explosion piece feeding device drives anti-explosion pieces to be conveyed to the jigs, the shaping device shapes products, the
rubber ring feeding device drives rubber rings to be fed, and the
internal resistance measuring device detects the
internal resistance of the products. Various working procedures such as anti-explosion piece feeding, top cover feeding,
welding, edge covering, shaping,
rubber ring feeding and internal resistance measuring are completed on one machine, the
automation degree is high, the
lithium battery cap is rapidly assembled, the
lithium battery cap does not need to be carried to another machine table for continuous shaping and internal resistance measuring, the production time is shortened, and the product competitiveness is enhanced.
