  • Patent number: 10403782
    Abstract: A method for laser scribing of thin-films for the manufacture of solar cell panels comprises loading a workpiece with the transparent substrate facing downwards in an input station of a first machine; biasing a reference edge of the workpiece against a front and rear stopper associated with a linear drive; translating the workpiece back and forth between the input station and output station and firing two or more laser beams at a first frequency substantially vertically through a space between the input and output stations to pass through the transparent substrate of the workpiece to scribe parallel lines on the front electrodes with reference to the edge of the workpiece in contact with the front and rear stoppers; and indexing the two or more laser sources and repeating the back and forth translation of the work piece between the input and output stations.

  • Publication number: 20170229604
    Abstract: The present invention describes an apparatus for a first laser scribing (P1) on the front electrode of a thin film solar cell panel and a similar apparatus for subsequent laser scribing (P2,P3) on the semiconductor layer and semiconductor layer/rear electrode. Before starting scribing process (P1), the left hand edge or reference line on the left hand edge on a workpiece is aligned substantively parallel to the linear drive before translating the workpiece on the apparatus. Similarly, the first and second scribed lines (Lp1,Lp2) formed during the P1 and P2 processes are separately aligned parallel to the linear drive before starting the relevant process (P2,P3). Alternatively, parallelism of the workpiece is carried out for each batch of the workpiece. In both apparatuses, the laser sources are mounted on independently motorised axes.

  • Patent number: 8727693
    Abstract: The present invention provides apparatuses for processing an object just as semiconductor chips and dies. The first embodiment comprises two or more pick and place heads (FIG. 1) which operate sequentially (ie leap frog) to pick components from a first location to a second. The second embodiment (FIG. 8) comprises a flipping head combined with a pick and place heads where an object is picked up by the flipping head, turned over and then presented to a pick and place head for relocation to an output.

  • Publication number: 20120181259
    Abstract: The present invention describes an apparatus (100) for a first laser scribing (P1) on the front electrode of a thin film solar cell panel and a similar apparatus (100a) for subsequent laser scribing (P2, P3) on the semiconductor layer and semiconductor layer/rear electrode. Before starting scribing process P1, the left hand edge or reference line on the left hand edge on a workpiece is aligned substantively parallel to the linear drive (140) before translating the workpiece on the apparatus (100). Similarly, the first and second scribed lines (Lp1, Lp2) formed during the P1 and P2 processes are separately aligned parallel to the linear drive (140) before starting the relevant process (P2, P3). Alternatively, parallelism of the workpiece is carried out for each batch of the workpiece. In both apparatuses (100, 100a), the laser sources (150) are mounted on independently motorized axes.
