B29C 6520

US Classification:

156499

Abstract:

A heat sealing machine for joining a battery casing and battery cover selectively operable in either a heating mode or a bonding mode comprising a battery casing station, a battery cover station and a battery casing/cover heater station operatively supported on a machine support frame, the battery casing station including a substantially horizontal support member to support the battery casing, the battery casing/cover heating station including a heater support frame movable between a first and second position pivotally mounted on the machine support frame having a casing/cover heater mounted on one end thereof and a counter balance mounted on the opposite end thereof, the battery cover station including a battery cover support frame movable between a first and second position pivotally mounted on the machine support frame having a battery cover support to support the battery cover pivotally attached to one end thereof and a counter balance mounted on the opposite end thereof, the machine support frame including a plurality of rollers for lateral movement of the individual battery casings thereon to move the battery casing laterally to the battery casing station, such that when the battery cover station and the battery casing/cover heater station are each in the second position the battery casing/cover heater station is operatively disposed between the battery casing and battery cover to heat the upper periphery of the battery casing and lower periphery of the battery cover and when the battery casing/cover heater station is in the first position and the battery cover station is in the second position the heated lower periphery of the battery cover engages the heated upper periphery of the battery casing to create a bond therebetween.
