What is a variable‑pitch module? How does it differ from a conventional linear slide?

Variable pitch module is a way to achieveMulti-station synchronous equidistant or unequal distance adjustmentThe core transmission components, single-axis module can complete multi-station variable distance operation, compact structure, small footprint. The essential difference with ordinary linear slide is:

• Ordinary linear slide: All sliders are fixed on the same rigid substrate and can only be translated as a whole, and the relative spacing between the sliders is immutable

• Variable pitch module: Built-in variable pitch screw or cam mechanism to drive multiple slidersUnfold or collapse synchronously during movement, to achieve "close row when grabbing, wide row when placing" or reverse action

In industries such as 3C electronics, semiconductors, medical devices, and lithium‑ion batteries, variable‑pitch modules can precisely pick multiple workpieces from a sorting tray at fixed intervals and place them at adjustable spacings, serving as a core component for multi‑station material handling and positioning in automated production lines.
