Abstract

PURPOSE:To surely seal a post of a sealed lead-acid battery having high reliability by heating and pressing a film-like container in which posts are placed between two films with a hot plate to which a sheet-like synthetic rubber is sticked. CONSTITUTION:A hot plate 1 has a heater 2 and a synthetic rubber sheet 3 such as silicon rubber sheet and Teflon rubber sheet, which is heat resistant, flexible, and heat conductive, sticked on the faced surfaces of the heater 2. The hot plate 1 is moved in an arrow direction by an air cylinder 4 to heat and press a film-like container 5 in which sheet-like posts 7 are placed between two films 7 and also an exhaust valve 6 is arranged, for a given time to seal the posts. The seal of the post having good reliability can be obtained without breakage of the resin sheet. The optimum thickness of the synthetic rubber sheet 1 is 1.0-2.0mm which is same as or thicker than the thickness of the post. If the thickness is 0.5mm or less, sufficient airtightness cannot be obtained and in addition deformation of the post or breakage of the film arises. If that exceeds 3.0mm, heat conductivity becomes poor and workability is decreased.

An electrode plate group 11 consisting of a positive electrode plate 8, a negative electrode plate 9, and a separator 1o is housed inside. This electrical sled has low oxygen permeability and moisture permeability, and has excellent tensile strength, etc. The inner surface in contact with the electrode plate group 11 is made of a polyolefin film with heat-welding properties, and the outer surface is made of polypropylene, polyethylene terephthalate, polyester, etc. It consists of a laminated film or sheet with a film of vinylidene chloride, etc.

った。Problems to be Solved by the Invention In such a conventional configuration, in order to thermally weld and seal the resin part of the pole pole and the film-like electric wire, a hot plate matching the shape of the pole pole is required; High precision is required for the position and dimensions of the pole poles, but this can easily cause deformation of the lead alloy for pole poles and damage to the coated epoxy resin, so mass production technology has been established to reliably seal the pole pole parts. It was difficult to do so.

The purpose is to establish a heat welding method for parts.

A film-like electric cell sandwiching pillars is heated and pressurized from the outside to heat weld and seal it.

Breakage of the coated epoxy film can also be prevented, and highly reliable liquid-tightness and airtightness can be obtained.

It can be a pole column sealing method.

In the figure, 1 is a heating heater 2 and a synthetic rubber sheet 3, such as silicone rubber or Teflon rubber, which has heat resistance, flexibility, and excellent thermal conductivity, is attached to the opposing surface, and an air cylinder for pressurization. A movable hot plate 4 is heated and pressurized by the hot plate 1 during thermal welding, and is a film-like electrical conductor made of polyethylene or the like having an exhaust valve 6 and sandwiching a sheet-like pole 7.

寸法幅５■、厚さ１．０■の条件で試験を行なった。With this configuration, silicone rubber was used as the cushioning material, and the thermal welding time and deformation of the pole pillars, destruction of the coated epoxy resin film, and airtightness were investigated by varying the temperature of the hot plate. The test was conducted under the following conditions: 1°C, a welding pressure of 50Kp, a pole width of 5cm, and a thickness of 1.0cm.
