The present invention relates to a method for constructing a sealing body for a button-type battery. Conventionally, ring packing with an L-shaped cross section made of engineering plastics such as nylon, polyacetal, and polypropylene used in button-type batteries, such as lithium batteries, silver oxide batteries, mercury batteries, and Nickel zinc batteries, and stainless steel plates. As shown in FIG. 4, a method of constructing a sealing body consisting of a dish-shaped container made of For 3,
A dish-shaped container 4 located on the upper surface and held by suction using vacuum pressure or a chuck-shaped jig.
The pressure pin 5 that descends at the same time pressurizes the dish-shaped container 4, so that the packing 3 and the dish-shaped container 4 are integrated as shown in FIG. In this case, when the outer diameter of the packing 3 is φ°, the inner diameter of the packing holding part formed by the transfer plate 1 and the guide 2, that is, the diameter φ1 that holds the outer periphery of the packing 3, is determined by the structure of the sealing body. , φ゜<φ 1 . That is, when the outer diameter of the dish-shaped container 4 is φ2 , and the inner diameter of the fitting surface of the packing 3 with the dish-shaped container is φ3 ,
This is because there is a relationship of φ 2 >φ 3 between the two, so it is necessary to provide a clearance sufficient to allow the outer circumferential surface of the packing to bulge outward when the sealing body is constructed. For this reason, the packing 3 held by the transfer plate 1 and the guide 2 is not in a completely fixed state, and the dish-shaped container 4 that is attracted to the pressing pin 5 may be stuck to the pin 5 due to variations in shape and dimensions. However, a phenomenon of eccentricity occurred, making it difficult to maintain a normal positional relationship when combined with the packing. The present invention has been made to solve the above-mentioned problems, and the present invention will be explained below based on drawings showing embodiments thereof. In FIG. 1, a dish-shaped container 4 with an upward opening and a dish-shaped container 4 with an upwardly facing opening are placed in a stepped hole of a movable lower mold 10 which is held so as to be able to descend freely by a guide pin 8 fixed to a fixed plate 7 and a coil spring 9. The packing 3 facing in the opposite direction is arranged one after the other, and pressure is applied from above by a movable upper die 15. This movable upper mold 15 is integrally provided with a ring-shaped press-fit piece for pressurizing at its lower part, and
A guide pin 12 for centering the packing is placed inside the press-fit piece so as to be biased by a coil spring 13 so as to always protrude downward. and a stop pin whose end is guided and raised by a pair of guide holes provided in the side surface of the upper mold. The movable upper mold 15 is lowered to attach the packing 3 and the dish-shaped container 4 to the movable lower mold 1.
It is constructed integrally within the hole of 0. Next, this series of configuration operations will be sequentially explained based on FIGS. 2 and 3. In FIG. 2, the dish-shaped container 4 and the packing 3 are each inserted into the stepped hole of the movable lower mold 10, which is held by the guide pin 8 so as to always protrude upward by the restoring stress of the coil spring 9. Position it as shown. That is, the dish-shaped container 4 is connected to the upper surface 8 of the guide pin 8.
a and the inner peripheral surface 10a of the movable lower mold 10 with a smaller diameter hole, and the packing 3 is held in the opposite direction by the upper inner peripheral surface 10b of the larger hole of the movable lower mold 10.
At this time, when the outer diameter of the dish-shaped container 4 is φ2 , the inner diameter of the container holding part 10a of the movable lower mold 10 holding it is φ4 , and the outer diameter of the packing 3 is φ°, When the inner diameter of the packing holding portion 10b of the movable lower die 10 is φ5 , the respective relationships are φ0 ≦ φ5 ,
φ 2 ≦φ 4 . That is, the dish-shaped container 4
The packing 3 is held in the stepped hole of the movable lower mold 10 so as not to be eccentric. In FIG. 3, the press-fitting piece 11 of the upper mold 15 that is descending is packed by a movable guide pin 12 that is always urged to protrude downward by the restoring stress of a coil spring 13 provided inside the press-fitting piece 11. Perform centering with the center hole of 3, and lower end surface 1 of press force 11 while descending.
1a abuts against the upper end surface 10a of the movable lower mold 10, descends until it abuts against the upper end surface 3a of the packing 3, and further pushes down the packing 3 and the movable lower mold 10 at the same time. At this time, guide pin 8
The outer peripheral part of the dish-shaped container 4 placed on the top is inserted into the packing 3 that descends from the upper part together with the press-fitting piece 11, and the inner bottom part 3b of the packing 3 and the upper end surface 4a of the dish-shaped container 4 are connected to each other. contact, and the construction of the sealing body is completed. Further, the guide pin 12 stops descending when it hits the inner circumferential edge step portion 4b of the dish-shaped container 4 during its descent. As explained above, since the assembly of the dish-shaped container 4 and the packing 3 is carried out within a mold that is provided concentrically, a normal and uniform sealing body can be constructed. In order to confirm the effect of the construction method of the present invention, the following table shows a sample of a silver oxide battery with an outer diameter of 11.6 mm and a height of 3.0 mm, in which the construction method of the present invention was adopted.
The figure shows the numerical values of the results of determining the quality of the sealing properties of 100 pieces of each of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 100 pieces of each of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 100 pieces of each of 100 pieces of 100 pieces of 100 pieces of 100 pieces of 1 and 100 pieces of B, which adopted the conventional construction method, were constructed, and the quality of the sealing characteristics was judged.
