Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention provides for a taped radial lead type electronic component to be guided and fed by a guide path of a fixed guide part. The present invention relates to a tape lifting prevention device for preventing tape lifting.

Generally, radial lead type electronic components are arranged by sandwiching the tips of two lead wires protruding from each electronic component between two pieces of tape at a constant interval, as shown in Figure 3. It is transported in rolled or zigzag packaging.

(Prior art) When a radial lead type electronic component taped in this way is sent to a taped component supply device, etc., it is not possible to guide the electronic component itself, so the tape portion is inserted into a groove-shaped guide path and guided. , the lead wires and electronic components are transported in a state where they protrude from the guide path. For example, when a taping part is unwound from a rolled package and inserted into a groove-shaped guide passage, the taping part tends to sag due to gravity, so the taping part being transported through the guide passage tends to sag by that amount. There is a possibility that it will float up. If the tape is separated from the electronic component using, for example, a cutting device in a state where the tape is lifted up during transportation, the accuracy of the product's dimensions will be affected.

In order to prevent this lifting, it is possible to provide a guide to hold down the top of the electronic component protruding from the guide path, but since the height of the taping component that protrudes from the guide path differs depending on the type of taping component, It is necessary to provide guides to match the taping parts each time, which makes setup changes complicated, and it is also necessary to prepare a variety of guides, which is uneconomical.

(Purpose of the invention) An object of the invention is to provide a tape lifting prevention device that can prevent the tape of a taped radial lead type electronic component from lifting from the guide path during transportation.

(Structure of the Invention) In order to achieve the above object, according to the present invention, a movable guide plate made of an elastic material is attached to the side surface of the lead wire that protrudes from the tape portion in the guide path, and the tape edge on the electronic component side. The movable guide plate is attached to the fixed guide part so as to be elastically abutted at a position slightly away from the fixed guide part, and at this time, the tip of the movable guide plate extends diagonally across the direction in which the electronic components are transferred. good.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows the packaging of a typical taped radial lead type electronic component. Lead wires 1 of a large number of electronic components are held in a state of being lined up at regular intervals and being sandwiched between two pieces of tape 2.
Two lead wires of a certain length and an electronic component 3 protrude from one side of the tape. The tape 2 has holes 4 between adjacent lead wires.

The device of the present invention has a fixed guide portion 20 for aligning the taped electronic components in a fixed posture as described above. In FIGS. 1 and 2, this fixed guide part 20 consists of a main body 24 having a vertical recess 22 for guiding the tape, and a cover plate 28 that forms a vertical tape guiding path 26 together with the recess 22 of the main body. Become.

Due to the guide passage 26 of this fixed guide part 20,
When guiding and feeding the tape part of a taped radial lead type electronic component, the electronic component 3
Since a fixed guide cannot be attached to the protruding side of the tape, there is a risk that the tape portion may be lifted out of the guide path during transportation. In order to prevent this, the movable guide section 30 is fixed onto the main body 24 of the fixed guide 20 with bolts. This movable guide section 30 is similar to the fixed guide section 20.
It consists of a base portion 32 fixed to the main body 26, and a movable guide plate 34 made of an elastic material and extending from the base portion. This movable guide plate is located at a position slightly away from the tape edge 2a (see also FIG. 3) on the side of the electronic component 3, and its tip portion protrudes above the tape portion within the guide path 26 during transfer. The lead wire 1 extends so as to come into contact with the side surface of the lead wire 1 with elastic force.

In FIG. 1, when the movable guide plate 34 does not come into contact with the lead wire 1 of the electronic component 3 being transferred in the direction of the arrow, it freely extends between the lead wires, but the tip of the movable guide plate 30 is lead wire 1
When it hits the side of the lead wire, it bends slightly inward due to its elasticity as shown by the imaginary line, and the movable guide plate 34 pushes the lead wire with a certain pressure, preventing the tape part of the electronic component from lifting up. . It should be noted that if two or more movable guide plates 30 are attached, the effect will be even greater.

(Effects of the invention) In this invention, the movable guide plate made of an elastic material applies elasticity to the side of the lead wire that protrudes from the tape portion in the guide path at a position slightly away from the edge of the tape on the electronic component side. The movable guide plate is attached to the fixed guide part so as to be in abutting contact with each other, and since the tip of the movable guide plate extends diagonally across the direction in which the electronic components are being transferred, the elastic guide plate properly guides the lead wires during transfer. As a result, lifting of the tape portion of the electronic component can be effectively prevented, and if a lead wire cutting device is provided in the guide path, the lead wire can be cut with correct dimensional accuracy.
