Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a clamping device for a capacitor element, and more particularly to a clamping device capable of accurately positioning and holding capacitor elements having different diameters.

(B) Prior art During the manufacturing process of the electrolytic capacitor, the element part of the capacitor element is held and transferred to the next processing device. As a conventional clamping device for holding the element portion of the capacitor element, as shown in FIG. 5, the tips of a pair of simultaneously rotating arms a extending substantially at right angles to the axis of the element portion e of the capacitor element c. In general, a structure of holding by a portion and a structure of holding by a tip portion of a pair of arms a'extending along the axis of the element portion e as shown in FIG. In any of the above cases, the V formed at the tip of each arm
The element part e is grasped and positioned by the grooves b and b ′. In the former case, if the element part has a small diameter, the
As shown in FIG. [A], the pair of arms grips the element part e in a substantially parallel state, but when the diameter is large (2 to 3 times smaller), it is shown in FIG. 5B. As you can see, the arm becomes wider. For this reason, even when the center of the element portion is always kept constant when the element portion is supplied to the clamp device regardless of the diameter of the element portion, when the element portion is actually gripped by the arm, the element portion is fitted into the V-shaped groove to cause center deviation. It is impossible to always hold the center at the same position and hold it regardless of the size of the raising element. Also in the latter case, the arm a'becomes wider as the diameter of the element portion increases as shown in FIG. 6B, and in this case, the entire V groove cannot be gripped and the element portion is not able to be gripped. Edge (edge on the opposite side of the end face from which the lead wire 1 projects)
You will only be able to grip. Therefore, there is a problem that the capacitor element cannot be firmly gripped and becomes unstable.

(C) Problem to be solved by the invention The problem to be solved by the invention is to hold down both end surfaces of the element part in a clamp device for a capacitor element, instead of holding the substantially circular outer peripheral surface of the element part by holding it. By gripping the capacitor element, the center of the capacitor element can always be held constant regardless of the size.

(D) Means for Solving the Problems The present invention is directed to a pair of arms arranged substantially parallel to each other, each of which has a stopper formed at a tip thereof to engage with one end surface of a capacitor element to be grasped, and between the pair of arms. In a clamp device for a capacitor element, which is movably arranged and has a pressing block that presses the capacitor element toward the stopper, and a spring that elastically presses the pressing block toward the stopper, the arm does not move. Fixed to the base,
The tips of the stoppers are extended in opposite directions to define a narrow gap between the tips of the stoppers, and the width of the gap is defined by a pair of lead wires extending from the one end face of the capacitor element. Grooves are formed to be substantially parallel to the surface defining the gap, grooves for receiving the arms are formed on both side surfaces of the pressing block, and at least one of upper and lower ends of the pressing block engages with an external operating device. It is configured by forming a convex portion that does.

(E) Operation In the above configuration, the element portion of the capacitor element is supplied into the gap between the pair of arms with the pressing block biased in the direction away from the stopper such that the axis of the capacitor element is substantially parallel to the arm. After that, when the bias of the pressing block is released, the pressing block is elastically pressed in the direction of the stopper and the stopper and the pressing block grip the element portion.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

A clamping device 1 of this embodiment is shown in FIGS. 1 and 2. The clamp device 1 includes a main body 2 having a base portion 21 and a pair of parallel arms 22 extending substantially at right angles from the base portion, and a pressing block 3 movably supported by the main body 2. A groove 24 into which a steel belt, which will be described later, is fitted is formed in the base portion 21 of the main body 2 on the rear surface (the surface opposite to the arm), and a mounting screw hole 25 is formed so as to penetrate therethrough in the front-rear direction. The pair of arms 22 has a gap between them
They are separated from each other so as to define 23, and a stopper 26 is formed at each tip. The main body 2 is made of synthetic resin, and the base 21, the arm 22 and the stopper 26 are integrally formed. Each stopper 26 projects toward the gap 23, but is separated so as to define a narrow gap 28 through which the lead wire 1 of the capacitor element is passed. As shown in FIG. 3, the portion of the stopper 26 that projects into the gap 23 has a surface 27 that engages with one end surface (the surface on the side where the lead wire 1 projects) of the element portion of the capacitor element to be gripped. Limited.

The pressing block 3 is also made of a synthetic resin material like the main body 2, and has grooves 31 for receiving the arms 22 of the main body on both side surfaces, as is apparent from FIG. A convex portion 32 is formed on the upper surface of the pressing block 3 so as to be engaged with an external operating device (not shown). The pressing block is elastically pressed toward the stopper 26 by the spring 4 provided between the base portion 21 and the pressing block in the gap 23.

The clamping device described above, as shown in FIG. 4, is mounted on a steel-filled belt 6 of known construction, in series side-by-side by receiving the belt in a groove 24, in holes 25 and in holes 61 of belt 6. It is fixed by the set screw 7 inserted.

In the clamp device having the above structure, when the belt 6 is sent to the supply position of the capacitor element, the convex portion 32 of the pressing block 3 is moved to the main body 2 by an external operating device (not shown) provided at the supply position. It is pressed against the spring 21 against the base 21 side. In this state, the capacitor element c is supplied into the gap 23 between the stopper 26 and the pressing block 3 while holding the pair of leads 1 with the lead wire 1 extended from the gap 28 between the stoppers 26. It At this time, the capacitor element c is supplied while being positioned by a chuck (not shown) of the supply device such that its center is always constant regardless of the size of the element portion e.

After that, when the pressing of the pressing block 3 by the operating device is released, the pressing block 3 is pressed by the spring 4 toward the stopper 26, and the surface 27 of the stopper 26 and the surface 33 of the pressing block press the both end surfaces of the element portion e. Hold it.

(G) Effect According to the clamp device of the present invention, the outer periphery of the element portion of the capacitor element is not received by the V-shaped groove formed in the pair of arms and is grasped by pressing the both end surfaces, but the grasping is performed. If the positioning is performed firmly at the time of making the center, it is possible to always hold the center constant even if the outer diameter dimension or the longitudinal direction (axial direction) dimension of the element portion is different.
