A flexible and continuous substrates-conveying sheet has a plurality of to be processed substrates disposed on or in it. A nondestructive transferring unit includes a plurality of first transferring rolls and a plurality of second transferring rolls. The first transferring rolls make contact with a first surface of the substrates-conveying sheet where that surface can have electrostatically-induced charge formed thereon. Each of the first transferring rolls includes a first central portion charged with a positive electric charge and a first outer portion surrounding the first central portion. The second transferring rolls make contact with the first surface of the substrates-conveying sheet. The second transferring rolls are disposed alternately with the first transferring rolls. Each of the second transferring rolls includes a second central portion charged with a negative electric charge and a second outer portion surrounding the second central portion.

A conveyor apparatus includes a conveyor belt supported by a first and a second roller assembly, a boom assembly housing the conveyor apparatus, the boom assembly including opposing side rails hosting roller assemblies at opposite ends thereof the side rails held parallel by a plurality of cross frame members. A drive motor connected to a chain sprocket and gear assembly fixed in turn to an axle of at least one of the roller assemblies drives the conveyor hydraulically. The conveyor apparatus further includes components protecting against wear from frictional contact with material conveyed, sudden static shock to an operator, and wherein the relatively non-conductive attributes of the component materials protect the operator from shock due to implied incidental contact with an external power source.

Disclosed herein is an adsorption device that adsorbs battery cells loaded in a loading bin and sequentially removes and transports the battery cells. The adsorption device includes a base plate capable of moving vertically and horizontally; a suction unit coupled to the base plate for adsorbing a battery cell located at a lower part of the base plate; and a push unit coupled to the base plate for striking the battery cell to produce a vibration in the battery cell adsorbed by the suction unit. The push unit includes a rod that is lifted up and down and strikes the top surface of the adsorbed battery cell to the lower end part, and the rod descends by the elastic force of a spring.
