Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rubber bushing mounting device, and more specifically, the present invention relates to a rubber bushing mounting device, and more specifically, the lead wire of a capacitor element that has been inserted in advance into a lead wire insertion hole of a rubber bushing is pulled, and the tuff of the lead wire is inserted into the rubber bushing insertion hole. It relates to a rubber bushing mounting device for fitting the rubber bushing.

In the capacitor manufacturing process, a capacitor element is inserted into an aluminum capacitor case, and a rubber bushing is fitted to the open end of the capacitor case to seal the inside of the case from the outside and to connect the lead wires of the capacitor element and the capacitor case. Trying to insulate.

In the manufacturing method of such a capacitor, first, the lead wire of the capacitor element with a lead wire is passed through the lead wire insertion hole of the rubber bushing, and the tab of the lead wire is fitted into the insertion hole to assemble the capacitor element and the rubber bushing. The assembly is then inserted into the capacitor case, but conventionally this is done by pushing the butt (lower part) of the capacitor element against a rubber bush, such as by inserting the tab into the insertion hole. Therefore, when inserted, the tab is pushed in the direction of the capacitor element (the insertion hole has a slightly larger diameter than the tab, so there is resistance to insertion), forming the capacitor element. Force acts on the connection between the electrode foil and the tab, causing it to loosen, resulting in a problem of electrical connection failure.

The present invention has been made in view of this problem, and its purpose is to hold and pull the lead wire of a capacitor element, move the capacitor element relative to the rubber bushing, and insert the tab of the lead wire into the insertion hole of the rubber bushing. An object of the present invention is to provide a rubber bushing mounting device which prevents poor contact between the tab and the electrode foil by inserting a rubber bushing into the support member and the lead wire of the capacitor element. A pair of openable and closable regulation plates for holding a capacitor element and a pair of openable and closable holding claws for holding a rubber bush into which a capacitor element is inserted are provided vertically on the support member, and the regulation plates and holding claws can be opened and closed separately. It has an operable rubber bushing holding mechanism, a movable part that is movable relative to the rubber bushing holding mechanism, and a lead wire holding claw that can be opened and closed on the movable part, and moves while holding the lead wire to the rubber bushing holding mechanism. IJ- which moves the capacitor element relative to the held rubber bush
It is equipped with a lead wire tensioning mechanism, and the lead wire is regulated by a stop plate while the rubber bush is held by the holding claw, or the lead wire is moved relative to the rubber bushing by holding the lead wire with the lead wire holding claw, thereby pulling the lead wire. The tab is inserted into the insertion hole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rubber bush mounting device according to the present invention will be described below with reference to the drawings.

The rubber bushing mounting device of this embodiment includes a rubber bushing holding mechanism 2 and a lead wire tensioning mechanism 4. A plurality of rubber bushing holding mechanisms 2 are arranged at equal intervals around the turntable 100 which is intermittently rotated by a known method. installed.

Each rubber bushing holding mechanism 2 consists of a lead wire regulating chuck 50 and a rubber bushing holding chuck 20 that are attached vertically to a pair of support pins 11 and 12 that are vertically fixed to the periphery of the turntable 100. The rubber bush holding chuck 20 has a pair of holding pawls 21 and 22 which are pivotally mounted on support pins 11 and 12 and biased toward each other in a closed position by springs (not shown). A semi-circular cutout 23,24 forming a retaining hole is formed in each case.

The retaining claws 21 and 22 have teeth 25 and 26 formed thereon.
are interlocked by interlocking with each other, and by rotating one of the holding claws (eg 22) in the direction of arrow X, both of the holding claws can be opened simultaneously.

The regulating chuck 30 includes a pair of regulating plates 51 and 32 which are pivotally attached to the support pins 11 and 12 and are urged by a spring 35 to a closed position (a position where the lead wire is sandwiched). A roller 34 is rotatably attached to the rear end of the regulation plate 61. The regulating plates 61 and 62 are engaged with each other by the protrusions 55 and 36, so that by rotating the regulating plate 61, the other regulating plate 62 can be rotated simultaneously.

The regulating plate 51 is further biased to the closed position by a spring 67. Note that 58 is a stopper for the regulation plate 51.

This regulating chuck opens as shown in FIG. 1 when the roller 64 at the rear end of the regulating plate 51 engages with the cam surface 60 of the cam plate 6 provided above the turn tip 10. .

The lead wire tensioning mechanism 4 includes a hollow support shaft 40 provided at a predetermined position around the turntable so as to be movable up and down, and a movable member, that is, a bracket 4 fixed to the upper end of the support 40.
1. An opening/closing shaft 42 provided inside the support shaft 40 that moves up and down with it but is rotatable relative to the support shaft, an opening/closing lever 45 fixed to the upper end of the opening/closing shaft 42, and an opening/closing lever 45 attached to the end of the bracket 41. It has a lead wire holding chuck 50.

The lead wire holding chuck 50 is pivotally attached to the end of the bracket 41 by support pins 51 and 52, respectively, and has a pair of holding claws 56 and 5 that are urged to the closed position by a spring 55.
It has 4. A roller 56 is attached to the rear end (upper end) of one of the holding claws 53. The holding claws 53 and 54 are interlocked by their arcuate gear parts 57 and 58 meshing with each other, so that by rotating one (the holding claw 55), the other can be rotated simultaneously. .

The lead wire tensioning mechanism 4 rotates the opening/closing lever in the direction of arrow Y in FIG. 4 by rotating the opening/closing shaft 42, thereby opening the holding claws 53,54.

In the rubber bushing mounting device having the above configuration, the rubber bushing holding mechanism holds the rubber bushing b with a rubber bushing holding chuck and the lead wire A 1 + -13 with a lead wire regulating chuck, as shown in FIG.
By holding and adjusting the capacitor element 2, the entire capacitor element is supported, and the capacitor element e is inserted into the insertion hole in advance.
A combination of a rubber bush through which a lead wire A 1+ 12 is inserted and a capacitor element is held. When the rubber bush comes to the position of the lead wire pulling mechanism together with the capacitor element due to the intermittent rotation of the turntable, the holding chuck 50 is opened by the opening/closing lever 43, and both the support shaft 40 and the opening/closing shaft 42 are lowered, and then the holding chuck 50
is closed and the lead wire 41 is held by a pair of holding claws 55 and 54.
-Keep e32.

Next, the support shaft and opening/closing shaft 42 rise together with the holding chuck. Therefore, the lead wire 11 t 132 is connected to the rubber bush a.
The large diameter tab tl of the lead wire is raised relative to the
lt2 is fitted into the lead wire insertion hole of the rubber bushing a. In this case lead wire 131 * -02 and tab tl
Since the connection with t2 is strong, even if some resistance is applied due to friction when the tab enters the insertion hole, the lead wire will not come out from the tab, and the connection between the tab and aluminum foil will not be removed. It has no effect on the

As is clear from the above explanation, according to the present invention, when attaching the rubber bushing to the capacitor element, all that is required is to pull back the G1 line, so there is no need to apply unnecessary force to the element. , but (
As a result, a rubber bush mounting device can be obtained that does not adversely affect the connection portion between the tab of the lead wire and the electrode foil, and does not cause electrical contact failure.
