The utility model can avoid using the laminated frame, and can achieve the same effect; edge bubbles generated by bending of the back glass in the laminating process can be perfectly solved; the use is high-efficient convenient, greatly improves product quality and produces line operating efficiency.

Description

A protection device for two glass photovoltaic module lamination
Technical Field
The utility model relates to a solar cell production field.
Background
It is known that the material and equipment abnormality of the photovoltaic module is a major problem in the generation of bubbles during the lamination process, but in the dual-glass photovoltaic module, in addition to the above problem, the unique back glass structure of the dual-glass photovoltaic module also has an influence on the lamination effect.
Because dual-glass photovoltaic module's thickness is greater than conventional photovoltaic module, at the laminator evacuation in-process, dual-glass photovoltaic module's stress point leads to the uneven and emergence deformation of upper glass atress at back glass's edge, becomes "protruding" shape state (fig. 4), and dual-glass is regional laminating all around, forms airtight space, leads to the inside air of POE can not in time discharge and in the gathering of glass edge, forms residual bubble.
The main solution to the problem is to prevent uneven stressing of the back glass during lamination of the dual glass assembly.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: how to solve dual glass assembly and in the problem of inhomogeneous atress of laminating in-process back glass appearance.
The utility model adopts the technical proposal that: the utility model provides a protection device for double-glass photovoltaic module lamination, includes four support columns, the height after the highly equal double-glass photovoltaic module lamination of every support column, when the pressure-bearing, four support columns are in double-glass photovoltaic module glass's upper left corner, lower left corner, upper right corner, lower right corner respectively.
The utility model has the advantages that: the traditional laminating frame (the frame is sleeved outside the double-glass photovoltaic assembly glass, such as the frame shaped like a Chinese character hui shown in figure 2) can seriously increase the cleaning rhythm after lamination, and the efficient operation of a production line is influenced, but the use of the laminating frame can be avoided, and the same effect can be achieved; edge bubbles generated by bending of the back glass in the laminating process can be perfectly solved; the use is high-efficient convenient, greatly improves product quality and produces line operating efficiency.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a conventional lamination box;
fig. 3 is a schematic view of a laminated state of the protective device without using the double glass photovoltaic module lamination;
FIG. 4 is a schematic diagram of the upper glass layer deformed into a convex shape due to uneven stress.
Detailed Description
This embodiment can satisfy the dual-glass photovoltaic module use of different thickness, therefore assumes thickness to be D after this dual-glass photovoltaic module lamination here, and the biggest subassembly safe width that the production line was allowed to pass through is K, and the width L that the subassembly flowed through the assembly line, the unit is mm, then:
the diameter C of the supporting column (cylinder) is designed to be 5 mm-C-L/2, and a cylinder with the diameter of 30mm is selected as a standard in general.
With photovoltaic module's fixed mode, the support column is located photovoltaic module's four angles.
And the supporting columns are fixed close to the photovoltaic module in a connecting mode with the photovoltaic module.
The production of double-glass edge bubbles has been introduced in the background art, and ordinary double-glass photovoltaic module comprises upper and lower glass with the thickness of 2.0, double-layer POE and a battery matrix, and the current process is mature relatively and is not described any more. When photovoltaic module had special use to need increase thickness, traditional technology just can't satisfy the production demand, and the effort of silica gel board to back glass can be more obvious in the lamination for the bubble problem is prominent. This patent design is simple, and convenient to use can perfectly solve similar problem.
