Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for supplying electronic components, which checks the electrical characteristics, terminal shapes and markings of electronic components and stores only good products on a carrier tape.

Prior Art A chip-shaped electronic component 1 is stored in a rectangular hole 3 in a component insertion recess of a plastic carrier tape 2, covered with a cover tape 4, wound onto a reel 5, and placed on a printed circuit board by an automatic mounting machine. It is attached to.

If the electronic component stored in this carrier tape 2 is a tantalum capacitor, it is a polarized component due to its small size, so if it is stored incorrectly due to the direction of storage, or the direction of the front and back when stored, it will be automatically installed. This may result in failure or incorrect mounting on the printed circuit board.

Problems to be Solved by the Invention Conventionally, this check was carried out by an inspector visually inspecting for the presence of defective products, and when defective products were found, it took time to correct them, reducing work efficiency.

Means for Solving the Problems In the present invention, an electronic component is held by a chuck provided on a turntable, and while the turntable rotates, the electrical characteristics of the electronic component and the bending shape of the terminal are inspected. The defective products are ejected from the turntable, the non-defective products are stored in the recess of the carrier tape, and while the carrier tape is moving, the quality of the stamps on the electronic components is determined, and the defective products are ejected. To provide a method for supplying electronic components to a carrier tape that replenishes and replenishes the discharged location with new non-defective products.

Embodiments Embodiments of the present invention will be described based on the drawings: 1
0 is a turntable which is rotated intermittently by an indexing device. This turntable 10 is provided with a chuck 12 for holding an electronic component 1. The chuck 10 may be of a vacuum suction type or a mechanism holding type that holds the chuck mechanically.

Reference numeral 8 denotes a transport chute for transporting the electronic component 1, which is connected to a turntable 10, and the electronic component 1 at the tip of the chute 8 is held by a chuck 12.

The electronic component 1 held by the chuck 12 is rotated intermittently by the turntable 10, and at the stopped position, the electrical characteristics such as the capacitance check 13 and the insulation resistance 14 are inspected, and the terminals 6 of the electronic component 1 are inspected. A recognition camera 16 detects whether the bending is done properly or whether the bent shape is good or bad. If a defect is detected in the above process, the defective product will be removed from the turntable 1.
It is removed at the ejection position 18 of 0.

The electronic components 1 detected as non-defective are stored one by one in the recessed square holes 3 of the carrier tape 2. The carrier tape 2 is wound around the material reel 20,
The product is wound onto a product reel 26 via a roller 22 guide plate 24. A cover reel 27 is guided by a roller 28, and a heat sealer 29 seals the carrier tape 2.
integrated with.

When the electronic component 1 is stored in the square hole 3 of the carrier tape, the carrier tape 2 moves in the direction of the arrow, and the next electronic component 1 is supplied.

The mark 7 attached to the surface of the electronic component housed in the carrier tape 2 is judged by a mark recognition camera 30 as to whether the mark is good or bad. The electronic component 1 with the defective stamp is discharged from the recessed square hole 3 as a defective product at the position 3.
It is discharged in 2.

The carrier tape 2 is discharged at the discharge position 18 and the stamp discharge position 32 of the turntable 10, and the hollow square hole 3 of the carrier tape 2 is filled with the square hole 3 from the good product supply tray 34 stored in advance.
Replenishment will be provided within.

The cover tape 4 is placed over the carrier tape 2 in which all the electronic components 1 of good quality are stored, and the tape 2 and the cover tape 4 are integrated with a heat sealer 29 and wound around a product reel 26.

Effects of the Invention The method of supplying electronic components to a carrier tape of the present invention prevents defective products such as bent terminals, defective markings, etc. from being stored in the carrier tape, and allows for subsequent automatic mounting. We were able to increase the installation rate on machines and completely eliminate accidents such as circuit burnout due to incorrect wiring.
