Abstract: A muscular strength assisting apparatus includes a muscular strength assisting portion that assists a user's muscular strength and a first connecting link including one side connected to one side of the muscular strength assisting portion and an opposite side rotatable relative to a shoulder of the user about a first rotation axis. The muscular strength assisting portion includes an upper arm module that assists muscular strength of an upper arm of the user and a link assembly including one side connected to one side of the upper arm module to be rotatable about a second rotation axis non-parallel to the first rotation axis and an opposite side disposed adjacent to a portion of a body of the user to be supported on the user.

Abstract: An over-soldering prevented tabbing device for manufacturing solar cell modules is disclosed in which the over-soldering is prevented from occurring in the tabbing device for performing the soldering process in manufacturing the solar cell modules. The over-soldering prevented tabbing device according to an embodiment of the present disclosure includes a solar cell module cell that is transported on a conveyor by a unit of cell; a soldering head installed above the solar cell module cell and having a built-in heat source that provides heat to solder the flux coated on the transported solar cell module cell; a driver reciprocating the soldering head in a direction in which the conveyor moves; and a controller controlling the driver.

Abstract: A substrate cleaning apparatus includes a bath in the form of a vessel filled with a cleaning liquid, a substrate guide disposed on the bottom of the vessel and configured to support at least one substrate vertically, a first sensing unit for sensing the substrate(s) supported by the guide, and a second sensing unit for sensing substrates or remnants thereof disposed on the bottom of the vessel. The first sensing unit has sensor elements installed on the opposite sides of the vessel as situated across from one another. The second sensing unit has sensor elements installed on both sides and on the bottom of the vessel for detecting substrates or remnants from damaged substrates lying on the bottom of the process chamber.
