The control device of a tape feeder, during the loading processing, in a case in which carrier tape that is preadjusted such that a length from a first cavity, which houses the electronic component and which is first from the leading end of the carrier tape among the multiple cavities, to the leading end of the carrier tape is a regulated length is inserted into the insertion section, starts conveyance of the carrier tape and makes a position of the first cavity a specified position in the feeder main body in accordance with a detection result of the detection sensor.

Tape feeder and carrier tape loading method

A feeder includes a feeder main body, a tape guide provided in feeder main body, a tape separating device to separate cover tape covering component storage sections, a tape conveyance path between the feeder main body and the tape guide and having recessed groove through which the component storage sections of the embossed carrier tape can be inserted, and a pressing device disposed in the recessed groove of the tape conveyance path to press the embossed carrier tape in a direction in which the embossed carrier tape is brought into abutment with the tape guide. The pressing device is positioned at both sides of the component storage sections in a width direction in of the recessed groove and presses flange sections of the embossed carrier tape without pressing the component storage sections.

Feeder

A non-splicing feeder including: multiple sprockets in a conveyance direction that accurately supply components stored in carrier tape to a supply position; a main body; a first sprocket on which first engaging protrusions are formed which is rotatably provided at supply position of main body; a second sprocket on which second engaging protrusions are formed which is rotatably provided on main body at a position on the downstream side in the conveyance direction of carrier tape with respect to first sprocket; wherein a tooth thickness dimension of second engaging protrusion is set to be smaller than a tooth thickness dimension of first engaging protrusion.

A feeder provided with: a feeder main body, on a rear section of which is formed a tape insertion section for inserting carrier tape that stores multiple components; a tape feeding path for feeding the carrier tape from rear to front, the tape feeding path being provided on the feeder main body so as to connect to the tape insertion section; and an insertion guiding member in which is formed a guiding groove capable of guiding the carrier tape to the tape insertion section when the carrier tape is inserted to the tape insertion section.

The present invention includes a tape peeling mechanism provided with a peeling member configured to enter a leading end surface in a feeding direction of fed component supply tape made from carrier tape and cover tape so as to peel the cover tape from the carrier tape, enabling a component to be supplied from at a component supply position, wherein the peeling member is displaced upwards after entering the leading end surface of the carrier tape as the component supply tape is fed. Accordingly, cover tape is reliably peeled without damaging components, and changeover work on the leading end of the component supply tape is not required.

Feeder device

A feeder, for which carrier tape is reliably inserted to a specified position without contacting engaging protrusions of sprocket, is provided. The feeder includes an entrance retaining member that pushes the carrier tape inserted into a tape insertion section towards a tape feeding path, a rotatable lever that raises the entrance retaining member when the carrier tape is inserted into the tape insertion section, and a contact prevention device that prevents contact between the carrier tape inserted into the tape insertion section and the engaging protrusions when the entrance retaining member is raised by the rotation of the lever.

A component mounting device which improves pickup accuracy of a component without delaying cycle time. A feeder which is capable of continuously feeding a first carrier tape and a second carrier tape to a component supply position without splicing, identification device for imaging a component which is a first component after switching from the first carrier tape to the second carrier tape using the imaging device and identifying a center position of the component before picking up the component, and correction control device for subjecting the X-axis slide to positional correction based on the identification carried out by the identification device such that the suction nozzle picks up the component at the center of the component.

Component mounting device

A feeder for which carrier tape is reliably inserted to a specified position, the feeder including entrance retaining member that pushes carrier tape inserted into tape insertion section towards tape feeding path, rotatable lever that raises entrance retaining member when carrier tape is inserted into tape insertion section, and stopper member that regulates the insertion position of the carrier tape inserted into tape insertion section to a specified position when entrance retaining member is raised by the rotation of lever.

A component supply device provided with a rail which transports a carrier tape, and a movable member which is provided above the rail and moves up and down, in which a gap above the carrier tape which passes a bottom portion of the movable member is blocked by the movable member.

Component supply device

A non-splicing feeder provided with multiple sprockets in the conveyance direction. Provided are a second sprocket that is rotatably provided at a position adjacent to a supply position of a main body and on which is formed a second engaging protrusion, a third sprocket that is rotatably provided at a position adjacent to an insertion section of the main body and on which is formed a third engaging protrusion, and a rail, the upper surface of which forms a conveyance path of a carrier tape, which is provided above the second sprocket and third sprocket, wherein space is formed above the rail between the second sprocket and third sprocket, and in a case in which engaging protrusions of both the third sprocket and second sprocket have engaged with engaging holes of a carrier tape, the carrier tape is slackened such that the carrier tape separates from the rail into space.

A feeder is provided with a pushing member that pushes the carrier tape against a rail, an engaging member engageable with indexing holes of the carrier tape, and an interlocking mechanism that moves an engaging member upwards by interlocking with the upwards movement of the pushing member. The engaging member engages with indexing holes of the carrier to restrict the movement of the carrier tape to the insertion section side. The interlocking mechanism separates the engaging member from the indexing holes of the carrier tape by interlocking upwards movement of the engaging member with upwards movement of the pushing member, allowing movement of the carrier tape in the conveyance direction.

A non-splicing feeder for which new carrier tape can be set safely is provided. The feeder includes a third sprocket rotatably provided on the insertion section of a main body, a fourth sprocket rotatably provided upstream from the third sprocket in the conveyance direction; third engaging protrusions which engage with engaging holes which are formed at a fixed angle on the outer circumference of a first sprocket, and fourth engaging protrusions which engage with engaging holes which are formed at only a portion of the outer circumference of the fourth sprocket.

A feeder provided with multiple types of tape peeling units, which are based on the type of carrier tape to be fed by the feeder, that are detachably attached to a tip section of the feeder; a cutter member, which is provided on the multiple types of tape peeling units, that peels one edge of cover tape of the carrier tape to reveal a component stored in a storage section; an identification mark provided on the multiple types of tape peeling units; an identification sensor, which is provided on main body of the feeder, that identifies the identification mark; and a comparing device that compares information recognized by the identification sensor and information of the component stored in the carrier tape.
