A component feeder capable of enhancing productivity is provided by that the component feeder includes a tape feeding device intermittently feeding a component housing tape constituted of a carrier tape having component housing parts formed with predetermined interval to contain respective electronic components, and a cover tape covering the component housing parts to prevent the components from jumping out from the component housing parts while the component housing tape wound on a housing tape reel is sequentially fed to a component extracting position, and an electronic component exposing device exposing the electronic components in the component housing parts to be allowed to be extracted, wherein the tape feeding device is constituted of a first feeding device and a second feeding device, and the electronic component exposing device is provided between the first feeding device and the second feeding device.

Component feeder

There is a need for providing an electronic component mounting apparatus, a component supply apparatus, and an electronic component mounting method capable of reducing inadvertent insertion of component supply tape and ensuring high reliability or capable of reducing wrong insertion of component supply tape, supplying new electronic component tape, and ensuring a high operation rate. Supply tape is inserted into an insertion entry of a component supply apparatus. An electronic component mounted on the supply tape is absorbed and is mounted on a printed board. Information about the electronic component mounted on the supply tape is read. Based on the read information, the component supply apparatus for inserting the supply tape is selected. The insertion entry is opened while it is closed when no supply tape is mounted.

Electronic component mounting apparatus

The invention provides a component feeding device where heat generation of a drive circuit is minimized and a printed board mounted with this drive circuit is miniaturized by forming an inexpensive structure using a single microcomputer and by energizing each of the servomotors only when necessary. In a component feeding unit of a dual lane type, a CPU in a microcomputer controls a start of driving of one of servomotors by energizing the servomotor through a drive circuit based on a component feeding signal for one lane outputted from a CPU of an electronic component mounting apparatus, and the CPU in the microcomputer controls one of the servomotors so that the servomotor is not energized when a component feeding signal for another lane is inputted before a predetermine time passes after a delay timer starts timekeeping when receiving a detection signal about rotation of the servomotor by a predetermined amount from an encoder detecting a rotation amount of the servomotor.

Electronic component feeding device

This invention provides a low-cost electronic component feeding device which stabilizes a pickup position of an electronic component and does not require a highly accurate sprocket. A component feeding unit is fixed to an adjusting jig, a recognition camera moves to a component pickup position and takes an image of each of feeding teeth formed around a sprocket, and a recognition processing portion performs recognition processing and calculates a position of each of the feeding teeth. In this case, for each of the numbers corresponding to the feeding teeth checked through a checking window, positional data of each of the feeding teeth which are a recognition processing result of the recognition processing portion are stored in a memory by using an input device. After such an adjusting operation of the component feeding units is completed, the component feeding units each mounted with a storage tape are fixed to the electronic component mounting apparatus. Then, an XY stage is driven to move a head unit to the component feeding unit, and the CPU corrects a pickup position of a suction nozzle based on the positional data.

Electronic component feeding device and electronic component counting apparatus having the same

The invention provides an electronic component mounting method which improves a work efficiency and enables pickup of electronic components without fail. A component feeding unit mounted with a master tape formed with pickup position indication holes is fixed to an adjusting jig. A recognition camera takes an image of a recognition mark to calculate a center position thereof, moves to a position corresponding to a component pickup position previously stored in a memory portion, and takes an image of the pickup position indication hole provided in the master tape to calculate a component pickup position. Data on a positional relationship between the recognition mark and the pickup position based on a result of this recognition processing are stored in a memory in the component feeding unit. The component feeding units each mounted with a storage tape are fixed to a base of an electronic component mounting apparatus. When an electronic component mounting operation is performed, a board recognition camera takes an image of the recognition mark provided in the component feeding unit to calculate a center position thereof, and the CPU corrects a pickup position of a suction nozzle based on the pickup position data stored in the memory.
