Pangkalahatang-ideya ng SUNPOWER Back Contact Cell Welding Machine SL-1000

       ▶  

Ang SL-1000 SUNPOWER Back Contact Cell Welding Machine ay isang ganap na awtomatikong stringer na espesyal na idinisenyo para sa pagwelding ng back contact (IBC/SUNPOWER) solar cell strings. Hindi tulad ng conventional tabber stringers para sa front-busbar cells, ang SL-1000 ay tumutugon sa natatanging hamon ng interconnection ng back contact cells kung saan ang parehong positive at negative electrodes ay matatagpuan sa likurang ibabaw. Ang makinang ito ay nagsasama ng advanced electromagnetic welding, high-precision CCD vision inspection, at SCARA four-axis robotic positioning upang makapaghatid ng maaasahan, high-throughput na produksyon ng back contact cell string.

Ang kumpletong sistema ay may kasamang A/B dual cell loading boxes, loading translational mechanical arm, cell transmission table, CCD + four-axis robot detection at positioning system, welding transmission table, electromagnetic welding module, welding ribbon material boxes, welding ribbon transport mechanism, welding ribbon positioning table, double welding ribbon gluing tables, welding ribbon placement module, at fully automatic unloading mechanism na may conveyor belt, cell string sucker, clean paper sucker, cell string box, at clean paper box.

Prinsipyo ng Paggawa:Ang loading translational mechanical arm ay kumukuha ng solar cells mula sa dual cell boxes at inilalagay ang mga ito sa cell transfer station, habang sabay na kinokolekta ang interleaving paper sa paper collection box. Ang transfer station ay naghahatid ng cells sa CCD detection at positioning station. Ang CCD camera ay kumukuha ng coordinate information at ipinapadala ito sa SCARA four-axis robot, na nagwawasto ng cell orientation at inilalagay ang bawat cell nang tumpak sa welding transfer station. Ang welding transfer station ay may maraming independently controlled temperature zones para sa optimal thermal management sa panahon ng string welding.

Samantala, ang welding ribbon transport mechanism ay kumukuha ng pre-cut solder ribbons mula sa ribbon material box at inihahatid ang mga ito sa positioning table, pagkatapos ay inililipat sa ribbon placement table. Ang ribbon laying mechanism at four-axis robot ay nagpapalit-palit ng operasyon upang makumpleto ang ribbon placement at cell stacking. Ang assembled ribbon-and-cell array ay naglalakbay mula sa welding transfer station patungo sa electromagnetic welding station, kung saan ang electromagnetic welding module ay kumukumpleto ng soldering. Ang mga natapos na cell strings ay dinadala sa unloading station sa pamamagitan ng conveyor belt, at ang unloading mechanism ay naglalagay ng strings sa cell string box na may clean paper interleaving upang maiwasan ang pagkakamot.

Mga Aplikasyon

Back Contact (IBC / SUNPOWER) Solar Module Production

The SL-1000 is purpose-built for manufacturing solar modules using SUNPOWER-type back contact cells. It is the core stringing equipment in any IBC or back contact solar panel production line, handling the critical step of interconnecting cells where all busbars are on the rear surface.

1/3 Cut and Full-Size Back Contact Cell Stringing

With support for both full-size (125x125 mm, 166x166 mm) and cut cells (125x62.5 mm, 125x41.67 mm, 166x41.5 mm), the SL-1000 serves production lines making standard back contact modules as well as advanced shingled or high-density back contact module designs.

High-Efficiency Premium Solar Panel Manufacturing

Back contact cells deliver higher efficiency and superior aesthetics due to the absence of front-side busbars. The SL-1000 enables manufacturers to produce premium, all-black solar panels targeting residential rooftop, commercial, and BIPV (Building Integrated Photovoltaic) markets.

Pilot Lines and R&D Facilities

With its adjustable welding parameters, flexible cell size compatibility, and detailed process monitoring, the SL-1000 is also well suited for research institutions and pilot production lines developing next-generation back contact cell technologies.

Solar Module Production Line Integration

The SL-1000 integrates seamlessly with upstream and downstream equipment in a complete solar panel production line, including cell laser cutting machines, layup machines, laminators, framing machines, EL testers, IV testers, and sun simulators supplied by Ooitech.
