Automatic laser cutting machine

Overview

Main components include a variety of optional lasers described as having high airborne intensity and an optimized cutting surface. The machine's basic function is Automatic laser non-destructive cutting and scribing, with multi-scribing switching optional for process 2 (Scribing 2 ~ 6). Cell size compatibility is 156 x 156 ~ 230x 230， thickness 120 ~ 300u m and capacity (scribing 2) is ≥10000P/H with a fragment rate of 0.03% or 0.05%. Startup rate is ≥98% and failure rate is ≤2%. Average laser power is specified as Slotted laser≥50w，Split laser≥300W with an adjustment range： 10% ~ 100% and a laser life of 20000 hrs. Slotting cutting process achieves line width ≤ 30um, heat affected zone ≤ 100um and cutting depth is adjustable, while the lobes cutting process is specified as having no heat affected zone, no micro crack and no damage to the surface of the battery. Compatibility is listed for Conventional double-sided PERC battery, TOPCON battery, hjt heterojunction battery. Loading detection uses an industrial camera ≥ 20 million pixels (including ng) and comprehensive positioning accuracy is Positioning deviation: ≤± 0.05mm; Angle deviation: ≤ 0.08 °; Scribing deviation ≤± 0.1mm. The machine provides 4 loading caches and 2 unloading caches and offers customization functions including feeding code scanning, grid line positioning, sheet turning, PL detection, accurate feeding, centralized feeding or AGV docking. User interface is a graphical operation interface and MES port reservation supports parameter setting, fault diagnosis, alarm, product statistics and status record. Power supply is 380V 50Hz / 33kw (maximum power consumption) with three-phase five wires; compressed air requirement is 0.5~0.8MPa， 1200LPM. Machine size is L3240 x W3810 x H2150(mm) and machine weight is 6000Kg. The automatic laser splitting machine is used for the automatic production of high-efficiency photovoltaic modules. The scribing module can reduce the string current and reduce the resistance loss, thereby improving the output power of the photovoltaic module. According to the provided production data, dividing a whole cell into half chips can reduce string current and series resistance loss and reportedly increases module power by 6 ~ 7W based on current mass production data of first-line photovoltaic module factories.
