The long side alignment plate is installed on the piston rod of the long side alignment cylinder. Two guide shafts are installed on the long side alignment plate. The vertical plate is provided with a guide sleeve that cooperates with the guide shaft. The short side alignment includes a short side push rod. A pulling cylinder, a return push plate, an X-axis slide rail, a return frame, a lifting cylinder, a short-side return plate and a Z-axis slide rail. The short-side push-pull cylinder is arranged on a workbench. A return push plate is installed on the piston rod of the short-side push-pull cylinder. The return push plate is slidably connected to the workbench through the X-axis slide rail. The return frame and the lifting cylinder are vertically installed on the return push plate. A short-side return plate is installed on the piston rod of the lifting cylinder. The short-side return plate is slidably connected to the return frame through the Z-axis slide rail.

4. The photovoltaic module paperless packaging line according to claim 1, characterized in that: The wooden pallet feeding mechanism includes a pallet machine and a manual support frame pasting station. The output end of the pallet machine is connected with a roller transmission line, and the side end of the roller transmission line is provided with a manual support frame pasting station. The manual support frame pasting station manually fixes the support frame to the edge of the wooden pallet by hot melt adhesive or self-tapping screws; the support frame is made of stainless steel, the surface of the support frame is galvanized, and the support frame is used for inserting single-chip photovoltaic modules.

5. A paperless packaging process for photovoltaic modules, characterized in that: The following steps are involved: S1. Wooden pallet assembly: the wooden pallet machine transports the wooden pallet to the roller transmission line, and the wooden pallet is transported to the manual support frame pasting station. The two support frames are manually fixed on the edge of the wooden pallet by VHB double-sided tape or self-tapping screws, and the lower cover cardboard is placed on the wooden pallet to prevent the photovoltaic modules from being scratched; S2. The wooden pallet is positioned and flipped. The wooden pallet is positioned at the pallet positioning mechanism. At this time, the wooden pallet is located on the L-shaped flip frame. The clamping assembly clamps the wooden pallet, and the flip mechanism flips the wooden pallet 90°. S3. The iron tray of photovoltaic modules is separated, and the loading elevator transports the stacked photovoltaic modules to the lifting and transplanting mechanism. The lifting and transplanting mechanism lifts the photovoltaic modules and separates them from the bottom iron tray. The iron tray is transported to the turnover tray transplanting area from the tray detachment trolley for turnover placement of photovoltaic modules; S4. Photovoltaic module positioning: the lifting and transplanting mechanism moves the photovoltaic module after the separation tray to the floating alignment platform, and locks the position of the module after the four corners of the photovoltaic module are aligned; S5. Insert installation, the lifting suction cup mechanism sucks the first photovoltaic module and inserts it into the support frame for fixing, and the remaining photovoltaic modules are moved to the upper wooden pallet by the lifting and transplanting mechanism; S6. The module is flipped, the photovoltaic module is attached to the wooden pallet, and the flipping mechanism flips it 90°. At this time, the wooden pallet is rotated from the side of the module to the bottom of the module; S7. Output strapping. The photovoltaic module with the wooden pallet at the bottom is transported to the first long side strapping station under the guidance of the support guide assembly. The corner guards are manually installed on the module, and the strapping machine fixes it with at least two strapping tapes on the long side; the module is moved to the first horizontal strapping station. Paper guards are manually added to the four corners of the module for protection, and the strapping machine fixes it with four strapping tapes horizontally; S8. Cold-drawn film, the component is moved to the cold-drawn film machine, and a PU cold-stretched film is applied to the outside of the component, with LONGI printed on the film; S9. Palletizing and taping. Components are transported to the palletizer, which stacks two components together. Components are moved to the second long-side taping station. The taping machine uses at least two strapping tapes on the long side to secure them. Components are moved to the second horizontal taping station. Two strips of fiberglass tape are manually pasted on the paper corners at both ends of the components to secure them as a whole to prevent them from tipping over. The taping machine uses at least two strapping tapes on the short side to secure them.
