Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic assembly manufacturing, and in particular relates to a full-size battery cell group automatic adsorption transfer device and a working method thereof. Background Art

[0002] At present, there are more and more shingled photovoltaic modules in photovoltaic modules. Conventional shingled photovoltaic modules mainly use one-dimensional strings of battery cells as units. After connecting into one-dimensional string units, they are arranged and combined into module-level battery units. The size of the one-dimensional string unit is approximately 0.16 meters in width and 2 meters in length. In the production process, linear suction cup groups are currently used for transportation.

[0003] In addition to conventional shingled modules, new shingled modules are also increasing. Among them, full-series-parallel shingled photovoltaic modules have excellent anti-shading and anti-hot spot performance. The layout process is to directly layout the module-level battery group on the shingled platform with a single cell as the unit, and then transport it to the next process. However, in the production process, full-series-parallel shingled photovoltaic modules will form a battery group with a width of more than 1 meter and a length of more than 2 meters. Such a large-format photovoltaic battery group cannot be operated and transported using ordinary suction cup groups. Summary of the invention

The negative pressure suction cup 3-3 is connected to a negative pressure vacuum generating device 3-5. The negative pressure suction cup 3-3 includes a suction cup body 3-3-1 and a support rod 3-3-2. The support rod 3-3-2 is connected to the suction cup mounting holes 3-4. The suction cup body 3-3-1 is preferably a flexible silicone suction cup. The support rod 3-3-2 is an elastic floating structure, which is elastically connected to the outer sleeve as a whole. When pressed down with force, the main structure of the negative pressure suction cup 3-3 can slide up and down to protect the adsorbed object from damage. The positioning module 4 is arranged on the bracket 3-2, the suction cup frame 3-1 is connected to the bracket 3-2 through the lifting device 2, and the bracket 3-2 is connected to the moving device 1; the moving device 1, the lifting device 2, the negative pressure vacuum generating device and the positioning module 4 are all connected to the control system.
