Abstract

PROBLEM TO BE SOLVED: To securely hold a battery inside a jig, and to prevent the generation of positional displacement, turn over and jumping-out of battery due to an impact such as a collision of jigs in a battery-carrying jig, which is formed into a hollow cylindrical shape, so as to house a battery therein, by providing plural magnets in an inside surface of the cylinder. SOLUTION: Plural magnets 2, desirably, multiple number of 2 at 4 or more magnets 2 are installed in an inside surface of a cylinder, so that a magnetic flux to be formed by these magnets 2 is distributed in the point symmetry around a center of a hollow cylindrical part. As a result, in the case where the battery is held in a jig 1, the battery is evenly attracted to the inner wall of the jig 1, and held in the non-contact condition inside of the jig 1. Shape- check of an upper and a lower surface of the battery is facilitated, and soiling of the battery by the jig 1 is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery, and more particularly to a jig for transporting a small button battery.

[0002]

2. Description of the Related Art FIG.
There is a small cylindrical type as shown in FIG. The cylindrical jig has a step formed on the inner surface thereof, and supports the bottom surface of the battery on the upper surface of the step to convey the battery.

[0003]

However, in the conventional battery transfer jig, the battery is only received and supported on the upper surface of the step portion of the jig. In some cases, the battery held in the jig was displaced, inverted, or jumped out of the jig. Further, when a certain battery is contaminated by liquid leakage or the like, the upper surface of the step portion of the jig is contaminated, so that another battery may be contaminated. Furthermore, when performing a visual inspection of the battery with the battery stored in the transport jig, it is necessary to see the entire upper and lower surfaces of the battery, but with the conventional transport jig, the battery bottom hidden by the step is There was a problem that the battery shape and the like could not be confirmed because the jig could not be seen from above and below.

Accordingly, the present invention is to securely hold a battery in a jig, and to prevent the battery held in the jig from being displaced, inverted, or popped out due to an impact due to collision between the jigs. While holding the battery without directly touching the jig without forming a step inside the jig,
Provided is a battery transport jig that can easily inspect the shape of a battery and does not stain the battery with the jig.

[0005]

In order to achieve the above object, a small battery carrying jig of the present invention has a hollow cylindrical shape and is provided with a plurality of magnets without providing a step on the inner surface of the cylindrical shape. And
The battery is held by these magnets. This prevents the batteries from being displaced, inverted, or popped out by the impact of the jigs,
Further, since the battery is held in a non-contact manner with the jig, the shape of the upper and lower surfaces of the battery can be inspected, and the battery is not stained by the jig.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
This is a battery transfer jig that contains batteries inside in the form of a hollow cylinder.A plurality of magnets are provided on the inner surface of the jig on the cross section of the cylinder, and the magnetic flux distribution of the jig is the same as that of the hollow part of the cylinder. The magnets are arranged so as to be symmetrical with respect to the center, and the battery is held by these magnets.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of the battery carrying jig of the present invention, and FIG. 2 is a transverse sectional view of the battery carrying jig.
On the inner surface of the cylindrical jig 1, four magnets 2 mounted with alternating polarities are arranged in a square on a horizontal cross section.

FIG. 1 shows an example in which four magnets 2 are mounted, but the same effect can be obtained even when five or more magnets are used.
In particular, when the number of magnets is four or more and is a multiple of two, the magnetic flux distribution tends to have a clear symmetric shape.

As shown in FIG. 2, since the magnetic flux 3 is distributed point-symmetrically with respect to the center 4 of the hollow portion of the cylinder, when the battery is held in the jig, the battery 5 is uniformly cured by the magnetic flux 3. It is attracted to the inner wall of the tool 1 and is held in the jig 1 in a non-contact state.

Further, by changing the magnetic flux density of the magnetic flux 3, the holding force can be changed depending on the size and weight of the battery 5.

Incidentally, an N pole and an S pole may be constituted by a plurality of magnets 2.

[0012]

As described above, according to the present invention, the battery can be held in a non-contact state with the jig without being displaced, inverted, or protruded by the impact of the jig collision. Has the effect that the shape inspection is easy and the battery is not contaminated.
