The apparatus for sealing the secondary battery comprises: a support block configured to support a bottom surface of one-side sealing part of the pouch; a sealing member comprising a sealing roller that moves in a longitudinal direction of the one-side sealing part in a state of pressing a top surface of the one-side sealing part supported on the support block to seal the one-side sealing part supported on the support block; and a straightening member configured to flatten a surface of the one-side sealing part on which the sealing roller passes.

The present invention relates to an apparatus for pressing a secondary battery. The apparatus for pressing a secondary battery comprises a disposing member on which the secondary battery comprising an electrode assembly and a pouch is disposed, and a pressing member configured to press the secondary battery disposed on the disposing member, wherein the pressing member comprises an accommodation part pressing jig configured to press an accommodation part of the pouch, in which the electrode assembly is accommodated, in the pouch of the secondary battery disposed on the disposing member, and a sealing part pressing jig configured to press a sealing part formed along an edge surface of the accommodation part in the pouch of the secondary battery disposed on the disposing member, wherein the sealing part pressing jig is coupled to a surface of the accommodation part pressing jig corresponding to the sealing part to press the sealing part through pressing force transmitted from the accommodation part pressing jig.

The present invention relates an electrode notching apparatus. The electrode notching apparatus comprises: a notching unit shaping an electrode into a predetermined pattern; a heating unit drying the electrode processed by the notching unit; and a collecting unit collecting the electrode dried by the heating unit, wherein the heating unit comprises: a heating body having a drying space through which the electrode supplied by the notching unit passes; and heating members directly heating a surface of the electrode passing through the drying space to dry moisture remaining on the electrode.

A pressing roll device, in which a unit cell passes between an upper roll and a lower roll, includes: the lower roll; the upper roll; a lower mount on which the lower roll is mounted and which is fixed in movement; an upper mount on which the upper roll is mounted and which is restricted by a bracket so as to ascend and descend by the bracket; and a stopper disposed between the lower mount and the upper mount so that the lower roll and the upper roll are spaced apart from each other.

Method for conveying an electrode strip for the production of electrical energy storage devices, comprising the steps of: conveying the electrode strip; gripping it at subsequent portions; detecting the position of each portion by means of a sensor; calculating at least one deviation between the relative position detected and a nominal position; training at least one artificial intelligence algorithm with a sequence of deviations; determining at least one expected deviation for at least one subsequent strip portion; and controlling the position of said subsequent strip portion so as to compensate for said at least one expected deviation.

A drum arranged for reeling and dividing an elongate web of sheet material to produce discrete stacks of web portions is provided. The drum includes a series of faces forming a web-receiving loop that extends around a central axis of the drum, each face of the drum being defined by a respective drum segment that is configured to support a respective stack of web portions of a web reeled onto the web-receiving loop. The drum segments are movable to enable the web-receiving loop to expand to increase tension in a web reeled onto the web-receiving loop to divide the elongate web into discrete stacks.

An apparatus for manufacturing an electrode assembly according to the present invention includes a conveyor configured to allow an electrode to travel; and a cutter configured to cut the traveling electrode to a predetermined size, wherein the cutter comprises: an upper cutting blade disposed above the electrode; an upper eccentric driver configured to eccentrically drive the upper cutting blade; a lower cutting blade disposed below the electrode in a direction corresponding to the upper cutting blade; and a lower eccentric driver configured to eccentrically drive the lower cutting blade.

A system for replacing a reel of material for the production of electrical energy storage devices and comprising a self-driving vehicle for transporting a reel from a storage or receiving station to a change station is described; at least one support spindle carried by the vehicle and configured to support the reel and to transfer it, at the change station, to a feeding unit of an automatic machine for the production of the storage devices; and a gripping member carried by the vehicle and comprising at least one gripper configured to receive and grip an initial flap of the reel supported by the support spindle and to keep such initial flap tensioned along an unwinding path of the same.

According to an embodiment, a stacking apparatus includes: a first precedent-stage conveyor unit that conveys first sheets; a second precedent-stage conveyor unit that conveys second sheets; a merging unit that guides, to a merge point, the first sheets output from the first precedent-stage conveyor unit and guides, to the merge point, the second sheets output from the second precedent-stage conveyor unit; a subsequent-stage conveyor unit that sequentially receives, at the merge point, the conveyed first sheets and the conveyed second sheets, and conveys the received first sheets and the received second sheets in order of the reception while lining up in a conveying direction; and a stacking unit that sequentially catches each of the first sheets and each of the second sheets and stacks, at a predetermined position, each of the first sheets and each of the second sheets in order of the catch.
