Tape feeder

A component supply device includes an introduction sprocket that rotates with an outer peripheral pin engaged with a feed hole of a carrier tape on a conveyance path, thereby conveying the carrier tape, and a wheel that has a plurality of recesses on an outer periphery, and receives the outer peripheral pin of the rotating introduction sprocket by the recess to rotate in accordance with rotation of the introduction sprocket. A contact surface of the outer peripheral pin contacting an inner surface of the recess and a contacted surface with which the outer peripheral pin contacts out of the inner surface of the recess are both formed of flat surfaces, and the contact surface and the contacted surface come into line contact with each other.

Component supply device

The component supply device includes a body, a first carrier tape transporter, a second carrier tape transporter, and a controller. The body includes a tape transport path. The first carrier tape transporter transports a carrier tape to a component pickup position. The second carrier tape transporter transports the carrier tape to the first carrier tape transporter. The controller is configured to communicate with the component installation device and control the first carrier tape transporter and the second carrier tape transporter in one operation mode selected from a plurality of operation modes.

Component supply device and method for operating component supply device

A component supply device that supplies a component stored in a carrier tape to a component mounting apparatus, the component supply device includes a curl corrector that corrects curl of an empty tape which is a carrier tape from which the component is picked up by the component mounting apparatus.

A tape feeder includes a tape guideway that has an insertion port, a first tape transporter that transports a leading tape to a component extraction position in the tape guideway, a second tape transporter that transports the following tape from the insertion port to the first tape transporter, a following tape holder that has a first supporter that supports one side of an uninserted portion of the following tape in a width direction from a lower side, and a second supporter that supports the other side of the uninserted portion in a width direction from the lower side, and holds the uninserted portion of the following tape, and a displacer that displaces the uninserted portion of the following tape from the following tape holder. A width of one end portion of the second supporter decreases toward the insertion port.

A tape feeder includes a gate, a gate drive mechanism, and a tape feed mechanism. The gate is provided in an insertion port through which a carrier tape storing components is inserted. In the gate drive mechanism, a tape feed mechanism which drives the gate in opening and closing directions feeds the components stored in the inserted carrier tape to a pickup position. The gate drive mechanism includes a spring member which biases the gate in the closing direction, and a solenoid which drives the gate in the opening direction against a biasing force of the spring member.

Tape feeder and component mounting device

A second tape conveying mechanismB includes a sprocketB allowed to rotate freely only in a first rotating direction corresponding to a tape conveying direction, and a first urging memberwhich urges and causes a carrier tapeto engage the sprocketB. When a preceding tape() engages the sprocketB and a subsequent tape() is inserted, the second tape conveying mechanismB abuts against a leading end of the subsequent tape() to prohibit entry of the subsequent tape(). After the preceding tape() passes a tape stoppera position of the second tape conveying mechanismB is changed from a tape entry prohibition position to a tape entry permission position.

A component supplying apparatus includes a main tape entering port, a component supply port through which components are picked up from a carrier tape, a main tape path extending in a body part from the main tape entering port to the underside of the component supply port, a top tape removing part removing the top tape from the carrier tape on the main tape path upstream of the component supply port, a sub tape entering port, a sub tape path meeting a slope path portion of the main tape path at a meeting point upstream of the top tape removing part, and at least one sprocket wheels engaging with the carrier tape on the main tape path downstream of the meeting point. A length of the sub tape path is shorter than a length of the main tape path from the main tape entering port to the meeting point.

Component supplying apparatus and component supplying method

A component supplying apparatus comprises a tape guide surface facing a lower surface of the carrier tape, a preceding tape contact part climbing onto a upper surface of the preceding carrier tape, and a subsequent tape blocking part configured to wait on the upstream side of the preceding tape contact part in a tape feeding direction while keeping a distance from the tape guide surface so as to enable the carrier tape to pass between the subsequent tape blocking part and the tape guide surface, and to move downwardly toward the preceding carrier tape when the preceding tape contact part is climbed onto the preceding carrier tape. The subsequent tape blocking part keeps the subsequent carrier tape waiting by contacting a front end of the subsequent carrier tape stacked on the preceding carrier tape onto which the preceding tape contact part climbs.

A component supplying apparatus comprises an inclined straight path Pwhich is for the carrier tape and which extends obliquely upward, a horizontal straight path Pwhich is for the carrier tape and which extends in the horizontal direction from a front end of the inclined path Pand runs through the component supply position Q, a first sprocket wheel engaging with the feed holes of the carrier tape within the inclined path P, a guide member locating the carrier tape in the width direction within the horizontal path, a top tape removing device disposed above the inclined path Pbetween the first sprocket wheel and the horizontal path Pand partially removing the top tape from the base tape so as to expose the components, and a sprocket wheel drive device rotating the first sprocket wheel.

A component supplying apparatus has a tape guide part for guiding a carrier tape, a blade for entering between a top tape and a base tape, and a first tape press part for facing the carrier tape on an upstream side of a top tape removing position. A first biasing part biases the first tape press part to have the carrier tape held between the tape guide part and the first tape press part and to attain positioning of the carrier tape in thickness direction thereof. A sprocket wheel wedges the carrier tape between the tape guide part and the first tape press part, and a second biasing part presses the carrier tape against the tape guide part by a second tape press part.
