ウタ缶12の外面が負極となる。2. Description of the Related Art Generally, in a manufacturing process of a cylindrical battery such as a lithium ion secondary battery, a cylindrical coil body 11 is inserted into a bottomed cylindrical outer can 12 as shown in FIGS. There is a step to do. Here, the coil body 11 is formed by integrally inserting a pipe 14 serving as a positive electrode into a winding center of an electrode coil 13 formed by winding a thin plate material into a cylindrical shape, and an insulating surface is provided on one end surface of the electrode coil 13. The sheet 15 is integrally attached. When the coil body 11 is inserted into the outer can 12, the coil body 11 is inserted such that one end surface to which the insulating sheet 15 is attached is in contact with the inner bottom surface of the outer can 12. In this assembled state, the outer surface of the outer can 12, which is the bottom surface in the state of the finished product, becomes the negative electrode.

で、この短絡状態を早期に検出する必要がある。In such an assembling process, the outer can 12 which becomes a positive electrode and a negative electrode due to a defect of the coil body 11 inserted into the outer can 12 or a missing component.
The insulation between them may be impaired. In this way, the insulation between the positive electrode and the negative electrode is impaired, and a short circuit between the positive electrode and the negative electrode results in a defective product that does not function as a battery. Therefore, it is necessary to detect this short-circuit state early.

きない。Conventionally, the inspection for this purpose mainly involves visually observing the appearance of the coil body 11 before being inserted into the outer can 12, and confirming whether there is any defect or checking the number of components for missing components. It is. That is, after the coil main body 11 is inserted into the outer can 12, the coil main body 11 cannot be visually checked, and therefore, only the visual confirmation before the insertion is performed. For this reason, it is not possible to detect damage to the coil body 11 and missing components that occur when the coil body 11 is inserted into the outer can 12.

In this destructive inspection method, since the coil main body 11 can be inspected after being inserted into the outer can 12, it is possible to inspect for missing components that occur at the time of insertion.

In addition, a large amount of cost and inspection time are required because of manual extraction and destruction. Further, since the broken coil body 11 and outer can 12 cannot be returned to the original manufacturing process, products are wasted as a result. In addition, the inspection content is only for checking the number of components, and cannot be inspected for damage.

It is formed in a tapered shape so that it can be easily inserted into the outer can 12. The position of the coil positioning block 29 is set so that the contactor for positive electrode 20 contacts the upper end of the pipe 14 and then contacts the upper end surface of the electrode coil 13 due to the lowering operation of the guide rod 28.

A compression spring 33 is provided between the compression spring 33 and the lower surface. This is a structure for retracting the coil positioning block 29 upward by the compression spring 33 so that a predetermined pressure or more is not applied to the electrode coil 13 when the coil positioning block 29 is pressed against the upper end surface of the electrode coil 13. It is.

The short circuit detecting circuit is forcibly short-circuited before the operation of the lifting drive actuator 26 shown in FIG. 1. The input state to the short-circuit inspection programmable logic controller 25 in this short circuit state causes the disconnection of the electric circuit. The presence or absence is detected. That is, if the short-circuit detection electric circuit is forcibly short-circuited by the solid-state relay 36 but there is no input to the short-circuit inspection programmable logic controller 25, it is assumed that the electric circuit is broken. Judgment is made and subsequent operations are stopped.

Thereafter, the lifting drive actuator 26 shown in FIG. 1 is operated, and the presence or absence of short circuit of the battery assembly is inspected by the positive contactor 20 and the chuck piece 21a.
【0027】次に、上記実施の形態の検査動作について

持する。First, the battery structure in which the coil main body 11 shown in FIG. 3 is inserted into the outer can 12 in the previous step flows in the direction of arrow A in FIG. Therefore, the entire chuck 21 and chuck mechanism 24 are moved in the direction of arrow B by an actuator (not shown) to open and close the chuck 21 to hold the outer can 12 at a predetermined inspection position.

面に確実に接触した正規の組み立て状態になる。Thereafter, the guide rod 28 continues to descend for a while, so that the lower end surface of the coil positioning block 29 contacts the upper end surface of the electrode coil 13 and presses the coil body 11 downward. For this reason, the coil main body 11 is brought into a regular assembled state in which the coil main body 11 reliably contacts the inner bottom surface of the outer can 12.

圧力が加わることを防止している。At this time, since the coil positioning block 29 integrated with the guide rod 28 is configured to be retractable upward by the compression spring 33, no excessive pressure is applied to the coil main body 11 and a constant pressure is always applied. . The same applies to the contactor 20 for the positive electrode.Since the contactor 20 for the positive electrode is retractably attached to the tip of the guide rod 28, it is possible to prevent an excessive pressure from being applied to the pipe 14. ing.

加工費を削減できる。That is, the presence / absence of a short circuit between the positive electrode and the negative electrode of the battery structure is substituted by a short circuit test between the outer can 12 and the pipe 14. For this reason, it is not necessary to perform a destructive inspection by sampling and a visual appearance inspection by visual inspection as in the related art, thereby improving work efficiency. In addition, since this short-circuit inspection can be incorporated in the manufacturing process of the battery assembly, it can be performed for all the test pieces while keeping the inspection standard constant, and the reliability of the inspection result is improved. Furthermore, by eliminating the destructive inspection, all non-defective products can be supplied to the post-process, leading to an improvement in productivity and the absence of items to be destroyed.
Processing costs can be reduced.

に、検査効率および信頼性も向上できる。According to the present invention, after the coil body is inserted into the outer can, the conductive portion is brought into contact with the outer can serving as the negative electrode, and the positive electrode contactor is inserted from the opening side of the outer can to form the pipe serving as the positive electrode. The contact between the positive electrode and the negative electrode is checked by checking the short-circuit between the positive electrode and the negative electrode. And inspection efficiency and reliability can be improved.

る。Further, since the contactor for the positive electrode is moved forward and backward by the guide rod and comes into contact with the pipe while pressing the pipe against the outer can, the contactor for the positive electrode and the negative electrode is almost in the same state as the finished product having the pipe inserted into the outer can. Check for short circuits.
