Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automatic simultaneous forming machine for a capacitor for an electronic device member (hereinafter, also simply referred to as a strip-shaped attachment piece) attached to the strip-shaped attachment piece.

(Prior Art) When mounting a capacitor for an electronic member on a printed circuit board or the like, a capacitor c attached in series to a strip-shaped attachment piece a made of cardboard provided with a feed hole b as shown in FIG. There is a manual process in which the pole wires C1 and C2 of the capacitor are inserted and soldered into the plus and minus holes provided on the printed circuit board as a member, but the pole wire C1 of the capacitor is connected to the plus and minus holes of the board. It caused an accident such as burning or failure of the capacitor due to mistakenly installing the pole of C2. In order to avoid this, forming means for press-cutting by changing the length of the pole wire, or molding by cutting one pole wire with a round bar and the other pole wire by flattening it and cutting it We are working to improve products that eliminate accidents due to incorrect installation due to incorrect work.

However, in this case, the forming process for cutting the capacitor from the strip-shaped attachment piece required press cutting of the conventional capacitor and two-step work in which the crushing work of one pole wire was machined in a separate process. Forming apparatus was desired.

(Problems to be solved by the present invention) In order to solve the above-mentioned problems when the capacitor is press-cut from the strip-shaped adhered piece, the present invention has one of the current poles of the capacitor shown in FIG. 2 and FIG. It is an object of the present invention to provide a mechanical device that automatically and simultaneously performs a process of cutting a bar wire and a process of crushing and cutting the other heteropolar wire.

(Means for Solving the Problem) The present invention is a mold mechanism including a lower mold fixed on a machine base and a movable upper mold that presses with a step, and a capacitor with the mold sandwiched in between. A first pedestal for setting the attached strip-shaped attachment piece and a second pedestal are provided, a feed guide mechanism is provided at a start end portion in contact with the first pedestal, and a transfer table is connected to a tip end portion in contact with the second pedestal. And a pressing plate is set on the upper surface of the band-shaped attachment piece, and a positioning cylinder provided with a positioning pin that is vertically movable in parallel with the transfer pedestal, and the positioning cylinder is laterally and laterally movable. A strip feed cylinder for the strip-shaped attachment piece is provided, and the strip-shaped attachment piece set on the die, the receiving table, and the transfer table is intermittently transferred to cut the pole wire on one side of the capacitor attached to the strip-shaped attachment piece and Simultaneous molding processing of smashing and cutting of different polarity wires It relates to an automatic device.

(Structure and operation of the embodiment) Referring to the drawings, the embodiment of the present invention is as follows: 1 is a frame of the machine, 2 is a substrate, 3 is a lower die of a die mechanism fixed to the substrate, and 4 is an upper die. The mold includes a cut portion 4a and a press portion 4b.

The upper mold 4 is a cylinder receiving frame 8 fixed on the substrate 2.
It is connected to the lower part of the cylinder shaft of the main cylinder 7 supported by the above through a shaft joint 9 and a slide receiver 6 in a vertically movable manner.

The slide receiver 6 is vertically slidably mounted on the guide shaft 5 standing on the board. The vertical movement of the upper mold is stable.
In this way, the upper mold 4 cooperates with the fixed lower mold 3 to mold the molded member of the capacitor. 10 is a speed adjusting unit of the mold mechanism. Reference numeral 11 is a first pedestal on the starting end side provided with the lower die of the die mechanism in between, and 12 is a second pedestal on the transfer side, which are connected to each other at substantially the same height as the lower die. 13 is the first on the starting side
Reference numeral 14 denotes a band-shaped attachment piece feed sprocket provided near the pedestal 11, and numeral 14 denotes a belt-shaped attachment piece transfer table continuously provided to the second pedestal 12. Reference numeral 15 is a transparent holding plate which is attached to the band-shaped attachment piece a set on the die, the receiving table, and the transfer table with a small interval. Reference numeral 16 is a starting edge locking portion of the strip-shaped attachment piece a, and 17 is a receiving roller. Reference numeral 18 is a positioning cylinder for a strip-shaped attachment piece that is connected to the second pedestal, and 19 is a positioning pin that moves up and down.
Position it by projecting and retracting. Reference numeral 20 is a feed cylinder for a band-shaped attachment piece that moves the positioning cylinder laterally, and 21 is a speed adjusting unit. 22 is an automatic control unit, 23
Indicates operation switches, lamps, etc., and 24 indicates the body case.

The structure of the present invention is as described above. When molding a capacitor, the strip-shaped attachment piece a is set on the upper surface of a mold, a pedestal, etc. and automatically fed.
After the crushed surface C3 of the pole wire C2 is flattened by 4b, the crushed surface C3 is moved to the cut portion 4a, and C1 and C2 are simultaneously formed and processed and stored in a tray (not shown) on the pedestal. In this case, the belt-shaped attachment piece has the starter end of the feed sprocket that protrudes into the feed hole of the roller and the belt-shaped attachment piece, and the tip end of the positioning pin of the positioning cylinder protrudes into the feed hole of the belt-shaped attachment piece, and the capacitor lower mold. If it is securely set between the upper mold and the upper mold and the cutting process of the capacitor is cut by the opening and closing action of the mold,
Simultaneously with the opening of the upper die, the cylinder of the positioning pin is pulled in the direction of the arrow by the pulling action of the feed sprocket and the pull-off sillinder, and the strip-shaped attachment piece a is moved in the transfer direction. The feed cylinder returns to the original position and the feed pin rises and projects into the feed hole next to the strip-shaped attachment piece.

That is, the feed sprocket at the machine head start point, the positioning pin at the tip end, the positioning cylinder, and the pulling feed cylinder cooperate with the die, the receiving table, and the strip-shaped attachment piece set on the transfer table to automatically and intermittently transfer the capacitor. The two poles of the foot portion are formed at the same time with different shapes.

(Effect) As described above, this molding machine was able to perform simultaneous crushing and cutting by mechanical processing in two steps, but since it is possible to perform simultaneous molding in one step, the molding efficiency is higher than that of conventional machines. It has the advantage that it doubles and greatly contributes to improvement of workability and labor saving.

Further, by providing a difference in the mounting holes for the pole wires to the substrate, etc., it is possible to reliably prevent the occurrence of accidents due to mounting mistakes.

For example, the diameter of the mounting hole of the round bar of the bipolar wire of the capacitor is 0.9 mm.
If the crushed pole wire has a crushed width of 1.1 mm, mistakes in the work due to mistaken mounting holes can be prevented, and the identification due to the difference in shape can be facilitated to improve the accuracy of the work.
