Abstract:
A sound wave testing device is provided. The sound wave testing device comprises at least one sound output unit for providing at least one first sound signal, at least one sound-collecting element disposed above the at least one sound output unit, at least one sound-receiving unit disposed at one end of the at least one sound-collecting element, and an isolating element disposed between the at least one sound output unit and the at least one sound-collecting element, in which the solar panel is disposed on the isolating element. The at least one first sound signal is transformed into at least one second sound signal while passing through the solar panel. The at least one second sound signal is received and transmitted to at least one sound-receiving unit, and the at least one second sound signal is transformed into at least one digital signal for output.
Abstract:
A testing apparatus for testing a solar panel is provided. The testing apparatus includes at least one sensor, at least one impact hammer and at least one adsorbing element. The testing apparatus adsorbs the solar panel with the at least one adsorbing element and the at least one sensor is disposed on the solar panel. At least one vibration is produced when the at least one impact hammer hits the solar panel. The at least one vibration is received and transformed into at least one digital signal by the at least one sensor. The at least one digital signal is then compared with a database to determine the yield of the solar panel.

Abstract:
A light impact unit for an impact assembly and an impact assembly are disclosed. The light impact unit includes an impact portion, a piston element, a transmission element and a driving portion. The impact portion includes a cavity in which the piston element is disposed. The transmission element has a first end and a second end which is opposite to the first end. The first end and the second end are connected to the piston element and the driving portion respectively. Therefore, when the driving portion provides an impact force intermittently through the transmission element to the piston element, the piston element will impact the impact portion and move in a reciprocating motion.
Abstract:
An impact generating assembly comprises an impact platform and a plurality of impact generating units is provided. Each of the impact generating units comprises a holder portion, a fixture device and an impact generating portion. The holder portion comprises a first inclined plane and a second inclined plane opposite the first inclined plane. The fixture device is disposed on the holder portion. The impact generating portion is disposed on the holder portion for providing a reciprocating motion. Each of the impact generating units is mounted to the impact platform by the fixture device, and the impact generating portion is adapted to produce a synchronous vibration on the impact platform through the impact platform.
Abstract:
An impact generator and an impact testing platform using the impact generator are provided. The impact generator has an axial direction, a radial direction and a tangential direction, which are substantially orthogonal to each other. The impact generator comprises a coil and a magnetic device. The coil winds around along the axial direction. The magnetic device is adjacent to the coil and configured to construct a magnetic field so that a plurality of magnetic field lines of the magnetic field all pass through the coil substantially along the radial direction. The current flows along the tangential direction in the coil substantially so that the magnetic device is actuated by a force along the axial direction and generates an impact outwards while a current is conducted into the coil.
