Description

[Detailed description of the invention] (Industrial application field) Tab terminals are made by welding a lead wire a of tin-plated or solder-plated copper-clad steel wire to one end of an aluminum round bar, and flattening the round bar. It has a structure in which the head is formed by crushing it.

Accordingly, one aspect of the present invention is an apparatus that separates tab terminals moving forward in a row one by one and supplies the tab terminals to the next process.

(Prior Art) Conventionally, as shown in Japanese Utility Model Application Publication No. 48-9338, lead wires a of a large number of tab terminals are inserted into a single feed groove in the front and back direction bored in a vibration table that vibrates back and forth. Then, the round bar part b' remaining at the lower end of the flat head is supported by the surface of the feed groove and arranged in a line, and the vibration table is vibrated back and forth.
There is one that advances the tab terminal along a feed groove.

(Problem to be Solved by the Invention) However, it is difficult to accurately separate the tab terminals that advance along the feed groove one by one from the front end of the feed groove and supply them to the next process. .

An object of the present invention is to accurately mechanically separate tab terminals one by one using a downward U-shaped piece provided at the front end of a feed groove and reciprocating from side to side, and to supply the tab terminals to the next process.

(Means for solving the problem) Lead wires a of a large number of tab terminals are inserted into a single feed groove 2 in the front and back direction bored in a vibration table 1 that vibrates in the front and back direction, The round bar portions remaining at the lower ends of are supported by the surface of the feed groove 2 and arranged in a line.

The lower end of the monopod 3a of the downward U-shaped piece 3 which reciprocates from side to side and is located at the front end of the vibration table l extends forward and projects a separating claw 4 toward the feed groove 2.

The lower end of the other leg 3b of the U-shaped piece 3 extends forward for a short length and projects a separating claw 5 toward the feed groove 2. Between the separating claw 4 and the lower end of the flat head of one tab terminal, the lower end of the other leg 3b of the U-shaped piece 3 extends forward. The spacing is approximately equal to the diameter of the remaining round bar portion.

(Function) When the vibration table 1 vibrates in the front-rear direction, the tab terminals lined up in the feed groove 2 move forward in sequence.

The downward two-shaped piece 3 extending from the front end of the vibration table l holds the round bar remaining at the lower end of the flat head of one tab terminal between the left and right separation claws 4.5, When the shaped piece 3 moves to the right in the direction of the arrow in FIG.
advances toward the feed groove 2, closes the groove 2, and prevents the primary tab terminal from advancing, and separates one tab terminal sandwiched between both separating claws 4.5 from the front end of the feed groove 2. Supply to the next process.

When the downward U-shaped piece 3 moves to the left, one separation claw 4 advances toward the feed groove 2 and closes the groove, and at the same time, the other separation claw 5 moves away from the feed groove 2 and opens the groove. The tab terminal moves forward and contacts the separation claw 4, causing the feed groove 2 to
When the downward U-shaped piece 3 moves to the right, the other separating claw 5 advances toward the feed groove 2 as described above to prevent the next tab terminal from advancing. ,−
One tab terminal is sandwiched between the separating claws 4 on the other side, and as the separating claws 4 on one side move away from the feed groove 2, both separating claws 4
, 5 is separated from the front end of the feed groove 2 and discharged.

(Example) As shown in FIG. 2, a connecting rod 6 connected to a downward U-shaped piece 3
is connected to the upper end of the stacking rod 7, and the lower end of the stacking rod 7, whose middle part is pivoted to the machine body, contacts the outer circumference of the cam 8, and moves the downward U-shaped piece 3 through the connecting rod 6 to the vibration table l. Move it back and forth from side to side while looking over the surface.

A hole in the front and back direction that is drilled in the center of the vibration table l that vibrates in the front and back direction.
Lead wires a of a large number of tab terminals are respectively inserted into the feed grooves 2 of the strips, and the lead wires a of the tab terminals are inserted into the feed grooves 2 of the strips.

The round bar part b' remaining at the bottom end of the aluminum head plate crushed into a flat shape is supported, and as the vibration table l vibrates, the tab terminals lined up in a row shake the lead wire a back and forth as the vibration table vibrates. Move forward toward the front end of l.

Between the separating claw 4 attached to the long forward extending portion 3a of the lower ends of both legs 3a and 3b of the U-shaped piece 3 and the separating claw 5 attached to the shorter forward extending portion 3 pin, there is one aluminum head. The spacing is approximately equal to the diameter of the round bar part at the lower end of the part, that is, the interval is longer than the diameter of one round bar part and shorter than that of the two round bar parts.

The tab terminal transfer apparatus shown in FIGS. 3 and 4 is an example of the first step after supplying tab terminals according to the present invention.

Reference numeral 9 denotes a transfer table, on both sides of which a vertically wavy bent portion IO is formed, and a magnet 11 is embedded in the center of the wavy bent portion IO along the length direction of the transfer table 9.

and to the rack 12 attached to the back side of the transfer table 9.

A pinion 13 installed on the fuselage is engaged and transferred along the rail R toward a chemical liquid tank (not shown).

Therefore, the downward U-shaped piece 3 that reciprocates left and right of the present invention
The tab terminals separated one by one by the pair of separating claws 4.5 are placed one by one in the vertically corrugated bent portion 10 formed on the side surface of the transfer table 9 that is transferred along the rail R. It is attracted by the magnet 11, held vertically, and moved toward the chemical liquid tank.

(Effect of 51 Light) In the present invention, the tab terminals that move forward in a line in a rear direction feed groove 2 bored in the vibrating table l that vibrates back and forth, and the downward two-shaped piece 3 that reciprocates left and right. The separation claws 4.5 provided on both legs open and close the feed groove 2 mutually, so that the tab terminals are pinched and taken out one by one from the feed groove 2 by both separation claws 4.5, and the tab terminals are removed from the front end of the - row tab terminal. One by one, each piece is reliably mechanically separated and fed to the next process. This effect is produced.
