Description

[Detailed description of the invention] An electrode terminal of an electrolytic capacitor, which is a lead wire made by welding a tin-plated iron wire to the head of an aluminum rod, is supplied between the upper mold and the lower mold of the press, and the head is pressed. Next, wrap aluminum foil with positive or negative polarity around the flattened head and pack it into a case to form an electrolytic capacitor.

By the way, if the head of the terminal is not correctly fed between the lower mold and the upper mold during pressing, the head may be pressed into an incorrect shape or a defective product with a bent lead wire will be produced.

If such defective products are mixed with a product that has been pressed into a regular shape and supplied to the next process, it will cause confusion in that process and become an obstacle to mass production.

This is an invention in which only products that have been pressed into a regular shape are taken out from the press.

To explain the embodiment shown in the drawings, reference numeral 1 denotes a clamp that can be opened and closed horizontally and moved back and forth toward the press body A. The lead wire a of the terminal is clamped by the left and right claws 1' and 1', and the clamp is moved forward. Place the head on the lower mold provided in the main body A, open it, then retreat, close it again, and clamp the lead wire a of the next terminal supplied from above.

The lower mold of main body A is the conventionally known Utility Model Publication No. 40-2131.
As shown in Publication No. 5, the upper die is elastically supported by a spring, and when the lower die presses the head part on the lower die, the lower die resists the spring supporting it. or descend.

B is a take-out device of the present invention, in which a long guide hole 3 is bored in an immovable horizontal base plate 2 in a diagonal direction toward the press body A, and the tip of the long hole 3 close to the press body A is hook-shaped. bent to,
Then, a protrusion (not shown) provided on the lower surface of the sliding table 4 superimposed on the plywood is engaged with this, a protrusion 5 provided on the upper surface is engaged with the forked tip of the operating rod 6, and the base of the operating rod 6 is connected to the cam. The slide table 4 is moved by the outer periphery of the press body A and moves back and forth obliquely and horizontally to the front of the press body A, and the remaining end 4' of the slide table 4 is turned to face the front of the press body A.

A spring 8 is stretched between the side surface of the base of the sliding table 4 and the front side of the base plate 2, and constantly presses the base of the operating rod 6 against the outer periphery of the cam 7 via the protrusion 5.

The left and right lower sides of a downward U-shaped support piece 9 are fixed to the sliding table 4, and an opening/closing piece 10 is inserted inside it, and a spring 11 is stretched between both 4 and 10 to form the tip of the opening/closing piece 10. The downwardly facing bending mold 10' is tightly pressed against the front end 4' of the sliding table 4 and closed, and the lead wire a is held in this portion.

Reference numeral 12 denotes an operating piece that pushes the roll 13 provided at the base of the opening/closing piece 10, and a cable 1 that is pivoted on the side surface of the sliding table 4 and connected thereto.
4 to '5+<, the actuating piece 12 rotates and pushes the roll 13 against the spring 11, and the bending type 10' of the opening/closing piece 10
opens.

15 is a spring for returning the operating piece 12; 16 is a cable 14;
The operating rod is actuated by a cam 17 to pull the cable 14.

Reference numeral 18 in FIG. 3 indicates a supply element that supplies electrode terminals from above to the clamp holder 1 which moves back and forth horizontally.

As the vibration table 20 supported by the bullet 19 is vibrated back and forth by a vibration motor (not shown), the upright terminals housed in the vibration table 20 move forward toward the tip of the vibration table 20 and stand up. The feeder 18 grips the head of the terminal at the tip of the vibrating table 20, rotates 45 degrees around the pivot 21, and falls down horizontally.At the same time, the feeder 18 opens and opens to the left and right of the gripper 1 in the retreated position. A portion of the lead wire a is supplied between the claws 1' and 1'.

In the present invention, when the clamp holder 1, which moves horizontally back and forth, moves forward, places the head of the electrode terminal on top of the lower mold in the press, and retreats, the upper mold descends and supports the lower mold together with the terminal. Press it while lowering it slightly against the spring force.

At this time, the operating rod 6 causes the sliding table 4 to advance diagonally along the elongated hole 3 of the base plate 2 with the bent mold 10' opened downward, and then move the protrusion 5 along the hook-shaped bend of the elongated hole 3. At the center, the front end 4'' of the slide table 4 is turned to face the front of the press and is positioned above the lead wire a.

Next, the terminal whose head has been compressed rises together with the lower die, and its lead wire a is interposed between the downwardly opened bending die 10'' and the front end 4' of the slide table.

Thereupon, the cable 14 is loosened, and the bending die 10' closes due to the elastic force of the spring 11, thereby clamping the lead wire a.

Then, the bending die 10' turns away from the front of the press to take out the lead wire a out of the press, and when the sliding table 4 retreats and returns to the old position, the cable 14 is pulled and the bending die 10' is turned away from the front of the press. ′ and release the terminal to be clamped.

In the present invention, the electrode terminal whose head part is flattened by the press is taken out by repeating such an operation, but the sliding table 4 advances obliquely along the guide slot 3 bored in the base plate 2 and presses the press body. A
Since the operating rod 6 is reciprocated horizontally with a constant amplitude by the cam 7, the position at which it stops in front of is always constant and never goes out of order.

However, if the head is not placed correctly on the lower die and the head is compressed into an incorrect shape or the lead wire is bent, the lead wire is not in the correct position, so the bent piece 10' opens downward. It can only be clamped between it and the front end 4' of the slide table.

In this way, the bent mold 10' cannot hold defective products, so defective products are not taken out from the main body A.

Next, when the slide table 4 retreats, the upper surface of the lower mold is constantly blown away from the side with compressed air, so that any defective products left behind are blown off to the outside of the press.

In the embodiment shown in the drawings, when pressing an electrode terminal, the lower mold of the press moves up and down, and the electrode terminal is inserted from below between the bending mold 10' and the front end 4' of the sliding table. However, in the present invention, the bending mold 10' and the front end 4' of the sliding table move forward from an oblique direction and then turn toward the front of the press, as shown by the broken line in FIG. Even in the case of a press that does not move up and down and is fixed at a fixed position, the electrode terminal after pressing is inserted from the front between the bending die 10' and the front end 4' of the sliding table and is securely held, making it possible to take it out from the press. can.

In short, according to the present invention, the sliding table 4 moves back and forth in a diagonal direction toward the press body A along the guiding long hole 3 bored in the base plate 2, and the front end 4' of the sliding table moves forward and backward toward the press body A. Turn to face the front of the press A, stop at a certain position in front of the press, and at this fixed position close the bending mold 10' of the opening/closing piece 10 and press the electrode terminal between it and the front end 4' of the sliding table. Since the lead wires are clamped, defective products with bent lead wires do not intervene between the bending mold 10' and the front end 4' of the sliding table, and only good products are correctly selected and taken out.

In addition, the bending mold 10' and the front end 4' of the sliding table rotate in the opposite direction to the forward path, that is, in the direction away from the front of the press, while holding the lead wire, so that the long head a of the terminal can be moved out of the press. This has the effect of being able to be taken out quickly, shortening the lifting and lowering cycle of the press, and improving the manufacturing efficiency of the terminal.

Furthermore, after turning, the bending claw 10'' and the front end 4'' of the sliding table retreat diagonally from the front of the press body A to release the electrode terminals, so they do not interfere with the operation of supplying the electrode terminals to the press body from the front. This effect is produced.
