Quick answer: This is Ooitech's complete solar panel laminator catalogue: ten models covering semi-automatic and fully automatic machines, from a 600 mm by 600 mm laboratory chamber up to 2600 mm by 1500 mm production platens. It includes the model naming convention, a technical specification comparison across all ten machines, individual specifications for each, common system descriptions, safety controls, key component brands, factory and installation requirements, warranty terms and operating notes. Chamber size is the first decision, because it fixes how many modules load at once; the second is whether one or two chambers suit your cycle, since a double-chamber machine keeps the vacuum pumps working while the other side loads. Temperature uniformity across the platen is the specification that decides laminate quality: a cold corner leaves uncured encapsulant that fails years later. Silicone oil and vacuum pump selection follow from the chamber volume and the cycle time you need.

1. Product Overview & Application

The solar panel laminator is the most critical process equipment in the photovoltaic module production line. It bonds multiple layers of materials — EVA encapsulant, tempered glass, backsheet, and solar cells — together through a controlled combination of heat and vacuum inside a sealed lamination chamber.

Ooitech offers a complete range of laminators from compact semi-automatic bench-top models to large-scale fully-automatic double-layer, triple-chamber production lines. All models are compatible with:

• Mono-crystalline silicon solar modules
• Poly-crystalline silicon solar modules
• Double-glass solar modules (bifacial)
• TOPCon, HJT and other advanced cell technologies

• Vacuum equipment: Ten sets of 2X-70 rotary vane pumps, two sets of ZJP600 Roots pumps
• Heating: Four sets of 72 kW heating stations (SD320 thermal oil)
• Each laminating chamber is independent; each layer can execute lamination separately
• Upper and lower high-temperature cloth systems equipped with roller brush devices for residue elimination
• Specialized maintenance platform with climbing ladder for 2nd-floor access (600 mm wide, 1800 mm height, 900 mm guardrail)

Cooling Stage (unique to BT2787)

• Same structural form as process stage, but configured with an industrial chiller for water circulation cooling of modules exiting the process chambers
• Cooling base plate: Q235 steel, 40 mm thickness, finely ground surface; internal perforations allow coolant flow
• Temperature measurement points on base plate: ≥5, real-time display
• Cooling stage vacuum pump: rotary vane pump, ≥70 L/s; 100 Pa in<90s

5. Common System Descriptions

The following descriptions apply to all full-automatic oil-heating models (OTCY-2446, 2658, 2666, 2787D, 2787DD, BT2787). Semi-automatic electric models share the same control and safety logic but have simplified mechanical structure.

5.1 Feeding System

• The feeding stage uses an anti-deviation conveyor belt to perfectly transition modules to the main laminating unit.
• Controlled by frequency conversion system + photoelectric positioning system + encoder fool-proofing system. Transmission speed is continuously adjustable from 4 to 14 m/min.
• Three operating modes available: Auto feeding, Manual feeding, and Emergency management (via transmission inching button).
• Photoelectric sensor at the end of the conveyor belt provides module protection and positioning. If positioning deviation is detected, modules cannot enter the lamination section (alarm triggered).
• Double-layer (BT2787, 2787DD) models use stacked belt loading platforms — each layer has its own independent loading unit.

5.2 Laminating / Curing Section

• Chamber structure: Each lamination chamber consists of an upper chamber (upper box) and a lower heating plate, separated by a silica gel plate with a sealable bead/pressing frame, forming two independent sub-chambers (upper and lower).
• Heating plate: Made of 60 mm thick Q235 steel plate. Surface is finished by fine grinding; surface irregularity ≤200 µm/m². Double-inlet and double-outlet pipeline design for heat-conducting oil.
• Heating rate: Not less than 1.5°C/min.
• Temperature deviation: ≤±2°C (standard); ≤±1.5°C (premium models).
• Temperature measurement: ≥5 points per heating plate, displayed in real-time on touch screen.
• Each sub-chamber can be independently vacuumed and inflated. The vacuum value is set and controlled — supports segmented / staged lamination profiles. A SMC pressure sensor monitors real-time pressure; a Pa-class vacuum gauge is installed in the lower chamber.
• Laminating section vacuum pump: 2X-70 rotary vane + ZJP600 Roots pump set. Pumping rate ≥630 m³/h (OTCY-2787D/DD) or ≥600 m³/h (2658/2666). Time to 100 Pa:<90 seconds.
• Curing section vacuum pump: 2X-70 rotary vane pump. Pumping rate ≥70 L/s. Time to 100 Pa:<90 seconds.
• Cover lifting: Working opening height 100–120 mm; ultimate opening height (maintenance) ≥250 mm.
• Positioning accuracy: Gear motor + frequency control + encoder system. Repeat positioning accuracy within ±10 mm.
• Upper and lower conveyor belts of the main laminating unit are equipped with roller brush cleaners to remove EVA/film residue from the high-temperature cloth.
• The heating plate is equipped with a special blowing device (on 2658/2666 models) to prevent the high-temperature cloth from sticking to the plate surface.

5.3 Unloading / Discharge Section

• Discharge conveyed by stainless steel rollers driven by frequency conversion system, speed adjustable to match feed and host machine speed.
• Optional: buffer-type stainless steel roller unloading.
• Photoelectric sensors at front and rear ends monitor discharge in real-time to prevent modules from falling.
• The discharge section includes a fan cooling function — fans activate automatically when modules are discharged to accelerate cooling.
• Double-layer models (BT2787, 2787DD) use stacked multi-roller conveyors with integrated air coolers for accelerated module cooling.

5.4 Transmission System

• Main machine transmission: Gear motor + frequency control speed + encoder control, driving high-temperature cloth via chain. Repeat positioning accuracy: ±10 mm.
• Feeding and discharging stages: Gear motor + frequency control speed to match main engine speed.
• High-temperature cloth is arranged in a large-cycle circular motion — multiple cloths connected in series, continuously circulating without disconnection during the entire transmission process. The connection/join points of upper and lower cloths do NOT contact the module surface.
• Synchronous gear design ensures upper and lower high-temperature cloth systems always move in synchrony.
• Chain tensioning design + anti-jumping gear device reduces chain looseness from wear, ensuring smooth, continuous transmission without chain breakage or jumping.

5.5 Lifting System

• Both laminating and curing stages use pneumatic lifting, controlled by three-position five-way solenoid valves.
• Key pneumatic components (cylinders, lifting solenoid valves, pneumatic solenoid valves) use Japanese SMC (or equivalent reputable) brand components.
• Each cylinder's inlet and outlet are equipped with exhaust throttle valves to adjust lifting speed, ensuring stable and synchronous cylinder movement.
• Independent air control safety system: A dedicated air safety circuit — separate from the main hoisting mechanism — provides a holding signal for each cylinder. This prevents the upper chamber from falling due to power outages, pipe bursts, or other abnormal causes.
• Double-layer 2787DD model: Uses 8-column pneumatic lifting arrangement per chamber for stability on the large-format platform.

5.6 Heating System (Oil Heating Models)

• The heating plate is heated by heat-conducting oil circulating through a perforated/drilled plate. Double-inlet and double-outlet pipeline design for uniform temperature distribution.
• Heating rate: ≥1.5°C/min.
• Temperature deviation: ≤±2°C (standard); ≤±1.5°C (BT2787, 2658 single-chamber).
• Multi-point temperature control with PID self-tuning technology (standard temperature module). Achieves excellent temperature uniformity.
• Heating station from qualified manufacturers: provides real-time monitoring of temperature and pressure, with automatic alarm and shutdown on over-temperature or over-pressure conditions.
• BT2787 uses SD320 thermal oil with four sets of 72 kW heating stations.
• Oil tank over-temperature alarm: engine stops and alarms if oil temperature exceeds 180°C.
• Operating procedure: Allow oil pump to run in normal circulation for at least 3 minutes before turning on heating. When shutting down: stop heating first, then turn off the oil pump. Do NOT turn off the hot oil pump when temperature is above 100°C.

5.7 Vacuum System

• Lamination chamber vacuum controlled by a high-vacuum butterfly valve (Roots pump set).
• Under working temperature conditions, the ultimate vacuum of the lamination chamber can reach below 40 Pa. In automatic operation mode, lamination chamber vacuum ≤100 Pa.
• Each chamber is equipped with a Japanese SMC zero differential pressure pneumatic membrane two-way solenoid valve (VXZ260KG) for vacuum chamber inflation. Inflation rate freely adjustable from 0–50 L/s (or 0–70 L/s on OTCY-2787D).
• Each chamber has an SMC pressure sensor for real-time chamber pressure monitoring. Touch screen displays live pressure. Lower chamber additionally equipped with a Pa-class vacuum gauge.
• The entire vacuum/pneumatic system is equipped with a manual backup operating system for manual inflation and venting during unexpected power failure, minimizing losses from fault conditions.

5.8 Control System

• Whole equipment controlled by PLC (Siemens) + Touch Screen (Kunlun Tongtai).
• Multi-recipe storage: Various process recipes (formulas) can be saved and recalled at any time, accommodating different manufacturers and material batches.
• Data persistence: Process parameters and setting data are automatically memorized and stored on every power cycle — no loss of settings.
• Lamination count statistics: Records production count per shift for scheduling, maintenance planning, and consumable replacement tracking.
• MES integration: Optional production process management system (MES) available upon user request.
• Three production modes selectable by operator: Manual, Semi-automatic, and Automatic. If an abnormality occurs during automatic operation, the machine can switch to manual mode to reduce losses.
• Three-stage lamination supported; vacuum and pressure values are independently set and controlled for each stage.
• High-end brand electrical components: superior performance, reliable quality, low replacement rate.
• Equipment cabling, piping, and installation accessories comply with national standards and relevant regulations.
• BT2787 features independent double touch screens (one per layer) for simultaneous independent control of each production layer.
