Sheet set apparatus for sealing preparation, output lead wire set apparatus for sealing preparation, and sealing preparation apparatus

A sheet set apparatus for sealing preparation, which performs sealing preparation of a photovoltaic portion disposed on one surface of a substrate, and a pair of lead wires connected to the portion and having one end portions forming output lead wires, said apparatus comprising:

• a sheet supply section which is disposed along a transport way for transporting said substrate with said one surface facing upwards, while said output lead wires disposed at an upstream position with respect to a transport remains direction, and which feeds a sheet from a roll;
• a sheet cutting section including a cutting mechanism which cuts a sealing sheet having a wire passing portion with said output lead wire passed therethrough and to be set on said substrate from a fed portion of said sheet;
• a sheet set section which comprises a transfer head of a vacuum suction type having a plurality of suction holes formed on a lower surface thereof, a head moving device to reciprocate/move the head over a sheet receiving position in said sheet cutting section and a sheet covering position in said transport way, and a head elevating device to raise/lower said transfer head in both said positions, and in which the transfer head attracts said sealing sheet from above at said sheet receiving position and stops attracting said sheet when said head reaches said sheet covering position;
• and
• a wire support section which includes a support chuck able to pinch a lower portion of an upward bent portion of said output lead wire, and reciprocates/moves the chuck over a pinching position for pinching said upward portion and a retreat position out of said transport way.

A sealing preparation apparatus which performs sealing preparation of a photovoltaic portion disposed on one surface of a substrate, and a pair of lead wires connected to the portion and having one end portions forming output lead wires, said apparatus comprising:

• a transport way to transport said substrate with said one surface faces upwards, while said output lead wires are remains disposed at an upstream position with respect to a transport direction;
• a first sheet set apparatus which includes a first transfer head of a vacuum suction type, which is disposed along said transport way, which cuts a first sealing sheet from a fed portion of a first sheet wound in a roll shape, and in which the first transport head attracts and transports the sealing sheet, and stops attracting the sealing sheet on said transport way, and the sealing sheet covers said substrate;
• a second sheet set apparatus which is disposed on a downstream side from the first sheet set apparatus in the transport direction, and which cuts a second sealing sheet from a fed portion of an electrically insulating second sheet wound in the roll shape, and covers said first sealing sheet with the second sealing sheet on said transport way;
• an output lead wire set apparatus which is disposed at the downstream position with respect to the second sheet set apparatus in the transport direction, and which comprises a pair of first bend guide sections including a first guide plate as a reference for bending said output lead wires, a pair of second bend guide sections including a second guide plate having one side portion as a reference for bending said output lead wires bent on a side of a central portion of a width direction of said substrate using said first guide plate as the reference and the other side portion as the reference for bending upwards said output lead wires bent using the one side portion as the reference, and a drawing robot including a drawing chuck to pinch said output lead wire and three-dimensionally move;
• a third sheet set apparatus which comprises a third transfer head of the vacuum suction type, which is disposed at the downstream position with respect to said output lead wire set apparatus in the transport direction, and which cuts a third sealing sheet having a first wire passing portion from a fed portion of a third sheet wound in the roll shape, and in which the third transfer head attracts and transports said third sealing sheet and stops attracting said the third sealing sheet on said transport way, and the third sealing sheet covers said second sealing sheet so as to pass said upward portion through said first wire passing portion;
• and
• a fourth sheet set apparatus which comprises a fourth transfer head of the vacuum suction type, which is disposed at the downstream position with respect to said third sheet set apparatus in the transport direction, and which cuts a fourth sealing sheet having a second wire passing portion from a fed portion of a fourth sheet wound in the roll shape, and in which the fourth transfer head attracts and transports the fourth sealing sheet and stops attracting said the fourth sealing sheet on said transport way, and the fourth sealing sheet covers said second and third sealing sheets on said substrate with said fourth sealing sheet so as to pass said upward portion through said second wire passing portion.
