摘要

A tape feeder comprises body (100) provided with tape feeding unit (200) to feed a carrier tape by a predetermined pitch. The tape-feeding unit comprises a cam slider, front and rear locators, fixed rail, movable rail, gate unit, vinyl cover discharging unit, drive unit (500), and pitch adjusting unit. A tape feeder comprises body provided with tape feeding unit to feed a carrier tape by a predetermined pitch. The tape-feeding unit comprises a cam slider, front and rear locators, fixed rail, movable rail, gate unit, vinyl cover discharging unit, drive unit, and pitch adjusting unit. The cam slider reciprocates horizontally and includes a restraint slot having a concave cam section and convex cam sections. The front and rear locators moves up and down while coming into alternate contact with the concave cam section and the convex cam sections by the reciprocating motion of the cam slider. Each of the front and rear locators comprises a pin holder provided at an upper portion to guide vertical movements of a plurality of lock pins, and a seesaw link to move up and down. The seesaw link has a base pin to support the bottom of each of the lock pins. The fixed rail guides a vertical movement of the front locator. The movable rail is coupled to the cam slider to guide a vertical movement of the rear locator. It horizontally moves in a horizontal rail section of the fixed rail by a feeding pitch of the carrier tape. The gate unit mounts the carrier tape and guide the carrier tape when the carrier tape is fed. The vinyl cover discharging unit includes first and second discharging gears (410, 420) engaging with each other, with a vinyl cover peeled off the carrier tape being discharged by a predetermined pitch by a rotation of the first and second discharging gears. The drive unit simultaneously drives an actuating rod of an air cylinder coupled to the tape feeding unit and first and/or second discharging gears of the vinyl cover-discharging unit. The pitch-adjusting unit is mounted to a predetermined portion of the body to limit a backward movement of the movable rail of the tape-feeding unit.
