This HORAD station feeds EVA from a roll 990–1450 mm wide, cuts strips, lays up to three long strips on the module glass and tacks them with three hot-stamping heads on each short edge. HORAD lists a 10–50 mm cutting length and ±1 mm placement accuracy. Send your strip drawing and EVA grade so HORAD can show how those figures apply to your module.

HORAD's integrated welding station joins jumper wires to cell strings while the module sits on its glass. It cuts busbar from a coil to length, bends upward Z-shaped leads and welds them to the jumpers, with a fume extractor on top. HORAD names full-screen and 3-cell/4-cell segmented patterns and lists 380 V / 9 kW and 2.5 T. Ask for the welding method, settings and joint test results for your layout.

This HORAD station cuts small EVA or EPE film patches, feeds them onto the module and also prints and places internal busbar barcode labels. Cutting, feeding and printing run in sync, and a camera picks and positions each label. HORAD quotes a fastest cycle of 12 seconds, utilization of 99% or more, 380 V / 8 kW and 2.5 T. Ask for patch sizes, the film build it accepts and placement tolerance.

The HORAD string-taping station sticks short pieces of tape across cell strings on the glass to hold them in place before lamination. A servo straightens the glass, coordinates set each tape point and a rotary cutter cuts tape to a fixed length. HORAD quotes 0.9 seconds per point, under 60 seconds for a refill, 380 V / 10 kW and 1.7 T. Your module cycle depends on how many points your pattern needs.

HORAD's conventional gantry lifts completed strings and lays them onto the module glass, working from both sides at once. It handles horizontal and vertical layouts and AB string arrangements, with buffer and manual loading positions. HORAD lists 380 V / 22 kW, 4 T and a 3600 × 3230 × 2000 mm frame. No cycle time or placement tolerance is published, so ask for both with the quotation.

This HORAD machine does layup and busbar work in one frame: it arranges cell strings, corrects their alignment, feeds busbar from a roll and joins it, then inspects the array. It takes 166–230 mm cells, strings of 820–1260 mm and busbar 0.18–0.40 mm thick. BC panels and busbar folding or hot pressing come as modifications to order.

A gantry on linear motors picks finished cell strings and sets them on the glass, guided by vision. HORAD says it handles horizontal and vertical layup and AB or BC string layouts. String flipping and solder-strip cutting cost extra, so name them in the quotation. It draws 22 kW, weighs 4.5 T and covers modules up to 2520 × 1450 mm.

After the film is laid, this HORAD station uses a camera to find any offset, straightens the glass, brushes the EVA flat and heats it so it stays put. It runs on 8 kW, weighs 2 T and is far shorter than the cutting stations at 3680 mm long. HORAD's correction rule switches from one pass to several at 20 mm, so ask how it behaves at that point.

The precision version of HORAD's EVA station trims film on all four sides with an upper and a lower knife before laying it on glass. HORAD rates the fine cut at ±0.5 mm and describes placement as highly accurate, without a number. Roll changes take under 50 seconds. Choose it when sheet edges must be clean and square on every side.

HORAD's EVA station pulls film off the roll under constant tension, cuts it and lays it on the glass, with a stated laying accuracy of ±1.5 mm. A hot-melt splice swaps rolls in under 50 seconds while the line keeps running. It takes glass from 1650 to 2550 mm long and draws 18 kW. Quote it against your own film grade and roll size.

HORAD's glass-labeling station sticks a barcode on the underside of module glass, then rereads it to check the label is there and the printed data are right. It offers semi-paste and full-paste modes, takes single and double glass, and lists a fastest cycle of 12 seconds with utilization of at least 99.5%. Panels run 1640–2500 × 985–1450 mm.

HORAD's automatic glass-loading station picks glass sheets by robot, removes the interleaf paper and feeds glass into the module line. An axial-flow fan clears dust and an ion-air rod reduces static. Swinging-angle suction cups help prevent double picks. HORAD lists 380 V / 15 kW, 0.6–0.8 MPa air, a 9450 × 3500 × 2650 mm frame and a weight of 4.2 T.
