Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic feeding device for taped axial lead type electronic components.

Typically, an axial lead type electronic component has lead wires 2 protruding from both sides of each electronic component 1, as shown in FIG.
．． Wrap the ends of tapes 2' with two tapes 3 and 3' sandwiched between them at regular intervals, or
Or it is transported in a zigzag-folded package.

(Prior art) When a worker inserts axial lead type electronic components taped with the same direction and polarity into a circuit board at a work site, he must cut each electronic component apart from the tape and then adjust the direction and polarity. Because electronic components had to be inserted into the board by hand while checking their polarity each time, errors in inserting the direction or polarity of electronic components sometimes occurred, resulting in poor work efficiency.

(Object of the Invention) The object of the present invention is to provide a taped axial lead type electronic component that is automatically fed in a constant position so that the electronic component can be inserted into the board without checking the direction and polarity. The purpose of the present invention is to provide an automatic feeding device.

(Structure of the Invention) In order to achieve the above object, the present invention provides a guide member having a guide path for guiding the electronic component while keeping the taped axial lead type electronic component in a constant posture, and A cut-form-clamp device for cutting the lead wire of an electronic component from the tape to size, forming it into a U-shape, and clamping it, and a guide member when the clamped electronic component is removed. An automatic feeding device for taped axial lead type electronic components may be provided, which is equipped with a feeding section for feeding the next electronic component in fixed quantities to the cutting-forming-clamping device.

(Effects of the Invention) According to this configuration of the present invention, the axial lead type electronic component whose direction and polarity are uniformly aligned in a taped state is guided in a constant posture to cut the lead wire. Since the electronic components can be pulled out from that state and immediately inserted into the board, there is no need to insert errors in the direction or polarity of the electronic components. sex becomes much better.

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

FIG. 1 shows a layout diagram of an automatic feeder for axial lead type electronic components according to the present invention. This device holds the taped electronic components in a certain position (horizontally in this example).
Introducing parts 10 and 1 for aligning the parts, a guide part 50 for guiding the taped electronic components whose posture has been aligned in the introducing part IO to the cant-forming-clamping device 60 in the same posture, and a guide part 50 to guide the taped electronic parts into a predetermined position. A cut-form-clamp device 60 for cutting the lead wire to the dimensions, forming it, and clamping it until an operator removes the product; and when removing the taped electronic component formed by cutting the lead wire. It also includes a feeding section 30 for feeding the next electronic component by a fixed amount.

The introducing section 10 and the sending section 30 are shown in FIGS. 2 and 3. In the introduction part 10, opposing groove-shaped guide passages 12.12' are formed to guide each tape 3.3' of the lead wire 2.2' extending from both sides of the electronic component 1, as shown in FIG. A guide member 14.14' is fixed on the frame 15 so as to do so. Each guide member 14.14' has a narrow plate 1
It is formed by fixing wide boards 1B' above and below 6.16'.

These guide members 14 , 14 ′ extend from the introduction section 10 to the cutting-forming-clamping device 60 .

In the feeding section 30, claws 32.32' for contacting and pushing the lead wires 2.2' on both sides of the electronic component are pivotally connected to a reciprocating member 36 by a pin 34, and this reciprocating member is connected to the frame. A fixed guide 38 attached to the vertical plate 11a of
It is slidably guided in the groove. The claws 32 and 32' are
Although the leaf spring 40 is biased clockwise around the pin 34 as seen in FIG.
It remains in the position shown in FIG. 2 because it comes into contact with the front end surface of.

In order to reciprocate the pawl 32 by a certain amount, the reciprocating member 3
A cylindrical follower 42 is attached to 6, and this follower fits into a cam groove 48 of a cam wheel 46 attached to a motor shaft '44. This cam groove 48 is
A curved line that reciprocates a certain amount in the direction of the motor axis is drawn on the circumference of the cam wheel.

As the cam wheel 46 rotates, the follower 42, and thus the pawl 32 engaging the leads, advances the electronic component by the distance between the leads of adjacent electronic components and retracts the same amount. When retracting, the inclined upper surface of the pawl 32 comes into contact with the next succeeding lead wire, so that the pawl 32 rotates counterclockwise against the leaf spring 40 and can be easily retreated.

Next, the cut-form-clamp device 60 will be explained with reference to FIGS. 5 to 7. A sliding member 68 having two movable cutting edges 66, 66' is guided in the vertical groove 64 of the frame 62 so as to be slidable up and down. The sliding member 68 includes
A conventional means (not shown) is connected for reciprocating this. On the other hand, the upper plate 70 fixed to the upper end of the frame 62 is formed with fixed cutting blades 72.72' projecting downward at positions facing the movable cutting blades 66.66'. These movable cutting edges 66.66' and fixed cutting edges 72.7
2' forms the cut portion. Furthermore, a slot-shaped female die 74 is provided in the center of the upper plate 70 as a molding part for forming the product with the lead wires cut into a U-shape. A male mold 76 is mounted on the sliding member 68 and is formed by bending the lead wires on both sides at right angles. At the tip of the male mold 76, only the edges at both ends that sandwich the electronic component protrude so as to engage only the lead wires on both sides of the electronic component l. Further, in the clamp portion, a clamp pin 80 is slidably fitted into a horizontal hole 78 orthogonal to the slot-shaped female mold 74 of the upper plate 70, and this clamp pin 80 is inserted into a long hole 82 extending through the hole 78.
A stopper 84 fixed to the upper plate 70 protrudes from this elongated hole, and a spring 86 is inserted. Therefore, the clamp pin 80 is biased by the spring 86 so as to protrude into the slot-shaped female mold 74 by the thickness of the lead wire, and at this time, the stopper 84 is in contact with the inner end of the elongated hole 82. A limit switch 88 is attached to the upper plate 70 as a product presence/absence sensor, facing the end of the crank bin 80 on the opposite side from the female die 74. Since the width of the male die 76 plus the thickness of the two lead wires corresponds to the inner dimension of the female die 74, the male die 76
Even if it enters the female mold 74, it will not press the crank bin if there are no electronic parts. Therefore, the product presence sensor 88 does not operate. In addition, from the introduction part 10 to the guide part 5
The guide members 14, 14' which have passed through 0 extend in the space below the top plate 70 on both sides of the cut.

(Operation) Next, the operation of the apparatus of the present invention configured as above will be explained.

The taped axial lead type electronic component is introduced into the guide member 14.14' extending through the introduction section 10 and the guide section 50.
After passing through the guide passage 12.12', the lead wire of the electronic component is placed in front of the claw 32.32' of the feed section 30 and brought into contact with it. The reciprocating member 36 of the feeding section 30 by rotating the motor;
Actuation of pawl 32 therefore delivers a fixed amount of electronic components. When the tape is fed a certain amount, the sliding member 68 rises from the position shown in FIG. As it rises, the tip protrusion pushes the lead wires on both sides of the electronic component, pushing the electronic component into the slot-shaped female mold 74, and bending the cut lead wire at right angles to form a U-shape. The male die continues to rise and is pushed up to the position indicated by the imaginary line in Figure 5. During the pushing-up process, the male die 76 of the crank bin 80 was protruding into the female die 74.
is pushed to the left by the thickness of the lead wire against the spring 86 to activate the product presence sensor 88, which causes the feed section 3
0 motor is stopped and the product is held in a clamped state by spring 86. When the worker manually pulls out the electronic component in the clamped state, the crank pin 80 protrudes into the female mold 74 again by the thickness of the lead wire, and the product leaves the contact point of the non-sensor 8, so that the motor of the feed section 30 It operates and begins feeding electronic components in fixed amounts. In the unlikely event that there is a part of the tape where no electronic parts are attached, in that case, even if the male die 76 enters the female die 74, there is no lead wire, so the crank bin 80 will not be pushed, and the product presence sensor 88 is not working. As a result, the male die 76 moves back, and the electronic component continues to be fed by a fixed amount, and the feeding stops when the electronic component is clamped by the clamp portion and the crank bin 80 is pushed.
