Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module production, and in particular to a tooling buffering and conveying station and a tooling circulation line. Background Art

[0002] One of the processes in the manufacturing process of photovoltaic modules is the lamination process. During lamination, a lamination frame is generally placed on the periphery of the photovoltaic module. The outline of the hollow notch in the middle of the lamination frame is similar to the outline of the photovoltaic module. Through the setting of the lamination frame, on the one hand, during lamination, the height of the lamination mechanism pressing down is limited to prevent the glass from being crushed and exploded, thus protecting the photovoltaic module; on the other hand, through the limitation of the hollow opening in the inner circle of the lamination frame, the double-layer glass in the photovoltaic module can be limited on all sides to prevent the double glass from being misaligned during the lamination process. After the lamination is completed, the lamination frame needs to be dismantled and transported back to the place where the lamination frame is installed for recycling. The prior art generally sets a lamination frame reflux conveyor line above the laminator to realize the reflux of the lamination frame, and transports the lamination frames refluxed above the laminator to the ground one by one.

[0050] In the present embodiment, the cache rack 20 is lifted and lowered by an elevator. When the elevator drives the cache rack 20 to rise to the tooling unloading station, the tools at the tooling unloading station are stacked and cached on the cache rack 20. After a certain amount is cached, the elevator drives the cache rack 20 down to the tooling conveying mechanism 19, and conveys the tools to the tooling conveying mechanism 19.
