DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a DI in an electronic component automatic insertion device or the like.
The present invention relates to a magazine storage type component supply device that extracts and supplies components one by one stored in a magazine (stick) such as a PIC.

[Prior Art] Electronic components to be inserted and inserted in an electronic component automatic insertion device and the like generally include taped axial lead electronic components, radial lead electronic components, stick-packed electronic components, etc. The component supply device supplies the electronic components one by one up to the chuck position for inserting the electronic components.

In particular, products that are stored in magazines (sticks) such as DIP ICs, and that are supplied one by one from this magazine (magazine storage type electronic parts) generally have a main body and fragile leads protruding from this main body. It is composed of lines and many are relatively heavy as a whole.

FIG. 4 shows a conventional magazine storage type component supply device.

In the drawings, 1 is a stick-shaped magazine that stores electronic components 2, 3 is an escapement unit that separates and drops the electronic components 2 stored in the magazine 1 one by one, and 4 is a predetermined position for the dropped electronic components 2. It is a parts receiving part which is positioned and received at A.

The electronic component 2 supplied from the escapement part 3 is received at the receiving position A in a state where the fragile tip lead wire 2a is positioned in contact with the receiving part 4a. The side wall of the component receiving part 4 is formed of a receiving plate 4b and a component pressing plate 4c, which are movable in the left-right direction in the drawing.
That is, after the electronic component 2 is received, first the component holding plate
4c moves to the right in the figure. The component holding plate 4c is a part of a chuck device for inserting an electronic component, is a pressing member when the electronic component is inserted into the printed board, and moves to the right in the drawing to perform the inserting operation of the electronic component. This parts holding plate 4c
Following this movement, the receiving plate 4b moves to the right, and the work holding lever 5 rotates in the direction (rightward) for releasing the pressing of the electronic component 2.

Therefore, the electronic component 2 pressed by the work pressing lever 5 drops downward and is placed in contact with the upper end surface of the receiving plate 4b. After that, the work holding lever 5 moves to the left to push the next electronic component 2 to receive the receiving plate 4b and the component holding plate c.
After integrally forming the receiving position A, and move to the left in the drawing to return to the position shown in FIG. 4 (a). By this restoring operation, the electronic component placed on the upper end surface of the receiving plate 4b falls into the receiving position A, and the tip lead wire portion 2a comes into contact with the receiving portion 4a and is positioned. .

[Problems to be Solved] Electronic components such as DIP ICs having a large number of lead wires are relatively heavy, and the tip lead wires 2a thereof are fragile and easily bent when a large impact is applied. However, in the above-described conventional electronic component supply device, the electronic component 2 placed on the receiving plate 4b is dropped straight to the receiving portion 4a,
Since it directly gives a big impact to the fragile tip lead wire 2a,
There was a great risk of bending the tip lead wire 2a. When the tip lead wire 2a is bent in this manner, the electronic component 2 cannot be accurately positioned, which may cause a supply error and eventually a malfunction such as a defective insertion of the electronic component on the printed circuit board, thus lowering the reliability of the device. There was a problem of letting it.

That is, in the above-described electronic component supply device, positioning is performed by bringing the fragile tip lead wire 2a into contact with the receiving portion 4a of the component receiving portion 4, so the tip lead wire 2a that serves as a reference for the positioning. However, various problems such as those mentioned above occur when the bend occurs.

Therefore, as shown in FIG. 4 (b), a means for receiving and positioning the electronic component body 2b having a large strength by the receiving portion 4a can be considered, but in this case, from the tip surface of the electronic component body 2b to the lead. There is a problem that it is impossible to perform highly accurate positioning uniformly due to factors such as different dimensions for each manufacturer and the presence of burrs when molded.

Note that the lead-to-lead dimensions of electronic components are defined by standards, and each manufacturer has the same dimensional accuracy.

The present invention has been made in consideration of the above problems,
It is possible to send relatively heavy electronic parts to the parts receiving part while mitigating the impact caused by dropping, and as a result, it is possible to perform highly accurate positioning based on fragile parts such as lead wires with high reliability. An object of the present invention is to provide a magazine storage type component supply device.

[Means for Solving Problems] In order to achieve the above object, the present invention stores a component in a magazine and supplies the component, and separates parts having a fragile part in one part along a part supply track and drops them one by one. In a magazine storage type component supply device for accurately positioning at the fragile portion, a magazine having an escapement that separates and drops the components having the fragile portion stored in the magazine one by one along a component supply track A holder,
The component receiving position when the component is dropped to the receiving position comprises a component receiving portion provided below the magazine holder in a state of being offset in a predetermined direction with respect to the component supply track of the magazine holder. The parts receiving part is at the upper end,
An inclined surface is formed to incline in the offset direction to reduce the falling speed of the component, and the fragile portion of the component that has fallen while decelerating via the inclined surface is locked to the lower end portion of the inclined surface. Forming a receiving part for positioning
A part of the component receiving portion is configured by a part of a chuck device that conveys a positioned component and supplies it to a predetermined position.
