This invention relates to the field of
varistor processing equipment technology, and particularly to a
varistor coating equipment, which includes a frame, a feeding
assembly, a
coating assembly, a transfer
assembly, a transition alignment assembly, and a receiving assembly. The feeding assembly has two
modes: random material vibration sorting and fixture fixed-point feeding. The limit structure is infinitely adjustable and adaptable to the feeding of varistors of various specifications from 4mm to 12mm. The
coating assembly integrates three-axis linkage spraying, workpiece rotation and flipping, insulating tape application, automatic glue replenishment, and overflow glue
recovery functions, and can complete double-sided all-round coating of the workpiece. Two independent transfer mechanisms transfer the workpiece in a time-sequential, full-area manner. The transition alignment assembly completes the
posture correction of the wet glued workpiece, and the receiving assembly realizes automatic limiting of finished products and layered stacking and collection. This invention achieves unmanned closed-loop
processing of the entire process, with high coating yield and high glue consumable utilization. It is suitable for both large-scale
mass production and small-batch prototyping, and is compatible with standardized production lines for electronic components.
