Description

Description: TECHNICAL FIELD The present invention relates to a device for supplying and inserting an axial electronic component using an axial electronic component series in which both ends of a lead wire of the axial electronic component are connected with tape. .

(Summary of the Invention) The present invention relates to a bending and bending of a lead wire of an axial electronic component in a device for supplying and inserting an axial electronic component using a series of axial electronic components formed by connecting both ends of a lead wire of the axial electronic component with a tape. It realizes molding and insertion with a rational and simple mechanism.

(Prior Art) Conventionally, as a device for automatically inserting an axial electronic component having a lead wire in the axial direction such as a resistor and a diode into a printed circuit board, an automatic component inserting device proposed in Japanese Patent Publication No. 56-10798 is available. is there. This device cuts the lead wire of the axial electronic parts with the upper cutter fixed to the main body by the under cutter swinging around the shaft, and corrects the positional deviation of the lead wire with the V groove of the under cutter. After that, the lead wire is bent and formed by using the movement of the inserter with respect to the body fixed to the main body side, and the electronic component is held by the inserter by using the force that the lead wire tries to spread to the outside. The electronic components can be immediately inserted into the printed circuit board by lowering and reversing the inserter.

Further, there is a structure in which the lead wire of an axial electronic component is cut and bent by a cutting and bending mechanism, and then this component is delivered to an insertion chuck via a connecting chuck, as disclosed in Japanese Patent Laid-Open No. 61-16599. It is proposed in Kaisho 61-74400.

(Problem to be Solved by the Invention) By the way, the mechanism of Japanese Patent Publication No. 56-10798 has a V-groove on the undercutter, which is a movable part, for correcting the position of the axial electronic part. If so, the position correction operation of the axial electronic component may become unstable. Moreover, there is a tendency that the shape of the undercutter becomes complicated. Furthermore, Japanese Examined Patent Publication No. 56-10798 has been proposed on the premise of supplying various axial electronic parts in which both ends of lead wires are fastened with adhesive tape (re-taping is required), and the axial electronic parts are also proposed. The supply mechanism is not replaceable.

On the other hand, the electronic parts after cutting and bending the lead wire are delivered to the insertion chuck through the connecting chuck.
The constructions of 16599 and JP-A-61-74400 need to have a connecting chuck and a mechanism associated therewith, which tends to complicate the construction.

In view of the above points, an object of the present invention is to provide a device for supplying and inserting an axial electronic component, which has a simple mechanism, a reliable operation, and a high speed.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention engages a lead wire of an axial electronic component ream formed by connecting both ends of a lead wire of the axial electronic component with tape. And a movable cutter, which cuts the lead wire of the axial electronic component transferred to the component supply position by the feed wheel, and a feed wheel that is mounted coaxially with the feed wheel and is integrated with the feed wheel. With a molding wheel that rotates, a supply portion in which a positioning groove that defines the position of the lead wire is formed on the outer edge portion of the molding wheel, and faces at a distance slightly wider than the thickness of the molding wheel. A pair of insertion guides that can be moved up and down along both end surfaces of the molding wheel, and a push rod that performs a descending operation, and are provided on opposite surfaces of the pair of insertion guides. A molding groove that engages with a lead wire of the axial electronic component separated at the component supply position is formed, and is movable between the supply unit and the printed board on which the component insertion hole is formed, and is movable up and down. An insertion head, and the pair of insertion guides are lowered along the both end faces of the molding wheel by the lowering operation of the insertion head, and the axial electronic components separated at the component supply position by the fixed cutter and the movable cutter. The lead wire of the component is bent and molded in the molding groove, is sandwiched by the pair of insertion guides, and is transferred onto the printed circuit board by the movement of the insertion head, and the lowering operation of the insertion guide and the push rod are performed. The lead wire molded of the axial electronic component is inserted into the component insertion hole by the descending operation.

(Operation) In the axial electronic component supply and insertion device of the present invention, the feed wheel for intermittently transferring the axial electronic component train is provided with the molding wheel so as to rotate integrally with the feed wheel. When the molding wheel is stopped, the movable cutter operates to cut the lead wire between the fixed cutter and the lead along with the movement of the insertion guide along the molding wheel (with the operation of biting into the molding wheel while sandwiching electronic components). The wire is bent and molded to obtain electronic parts that are generally U-shaped. After the lead wire is molded, the insertion guide can hold the electronic component and move to the electronic component insertion position of the printed circuit board as it is.

In this case, the insertion guide itself can be used for lead wire molding,
The structure is simple. Further, since the lead wire can be positioned by forming the positioning groove on the molding wheel side, the movable cutter or the fixed cutter does not need a groove for positioning or correcting the lead wire, which simplifies the cutter structure. The cutter can be operated at high speed.
