example 1

[0128] Example 1 (continuous vacuum lamination processing system)

[0129] In this example, the operation of the continuous vacuum lamination processing system of the present invention is carried out as follows.

[0130] In this example, the figure 1 , 2 with the device shown in 4.

[0131] in accordance with Figure 11 The stacking pattern shown forms a stack of components needed to produce solar modules.

[0132] Figure 11 , reference numeral 801 denotes a substrate serving as a mounting stand. The substrate 801 includes a 1.6 mm thick weather-resistant steel plate (trade name: BONDE steel plate, produced by Nippon Steel Corporation) with a size of 1450 mm×600 mm and a phosphoric acid-treated surface.

[0133] On the phosphoric acid-treated surface (hereinafter referred to as the front surface) of the steel plate used as the base plate 801, an annular vacuum tube with an external dimension of 1400 mm × 5950 mm is arranged, and a group of ventilation holes are separ...

example 2

[0164] Example 2 (continuous vacuum lamination processing system)

[0165] In this example, the continuous vacuum lamination processing system of the present invention was practically applied in a manner similar to that of Example 1 described below.

[0166] In this example using figure 1 , 2 with the device shown in 3. In particular, the procedure used in this example is the same as that used in Example 1, except that the Figure 4 The device shown is changed to its variant i.e. Figure 5 In the double-column form shown in, each column includes a take-out work area and a material stack work area to replace Figure 4 It is a single-column form consisting of a take-out work area and a material stack work area.

[0167] As for the components, container, evacuation tube, etc. related to this vacuum lamination apparatus, they are the same as those shown in Example 1.

[0168] In this example, the steps for producing solar cell modules of Example 1 are repeated, but the si...

example 3

[0180] Example 3 (vacuum lamination equipment)

[0181] In this example, depending on Figures 6 to 9 Vacuum lamination equipment was prepared in the manner shown. which uses the previous reference Figures 6 to 9 the materials mentioned.

[0182] In this example, an evacuation pipe 601 is provided at a predetermined position in the front surface of a substrate 602 serving as a mount. Spot welding is then performed between the vacuum tube 601 and the substrate 602 at intervals of 15 cm, whereby intermittent partial welds 603 are formed to fix the vacuum tube to the front surface of the substrate. A sealant 604 is then injected from the outside between the evacuated tube and the front surface of the substrate to fill the gap formed therebetween by the aforementioned spot welding.

[0183] The base plate 602 is made of galvanized steel plate with a thickness of 1.6 mm, a size of 1450 mm×6000 mm, and a front surface with an average centerline height of about 0.8 μm. The va...

Abstract

The continuous vacuum lamination processing system includes at least a lamination work area where necessary components are piled up to form a stack subject to vacuum lamination treatment, a vacuum work area for evacuating the stack body, and a heat treatment work area for the stack body, and the work areas are adjacent to each other and arranged in a circle ;The formation of stacks in the lamination work area is carried out on a batch of vacuum lamination devices that can be selectively loaded or unloaded and selectively entered into each work area, and the stacks are continuously vacuum laminated on such devices At the same time, make each device successively pass through the above-mentioned work areas according to a given order. Vacuum lamination equipment suitable as the vacuum lamination device in this system is also given.

Description

field of invention [0001] The present invention relates to a continuous vacuum lamination processing system. More particularly, the present invention relates to a continuous vacuum lamination process system capable of mass-producing solar cell modules with high yield and a vacuum lamination apparatus suitable for producing solar cell modules. Background technique [0002] Vacuum lamination equipment is known which is used in the final stage of the production process of semiconductor devices such as solar cells etc. which are exposed to the outside air during use, in order to seal such semiconductor devices so that they can sufficiently withstand the ambient temperature Changes in humidity and resistance to impact or damage. It is hoped that the solar cell modules produced by this vacuum lamination equipment can be used as a power source that provides clean energy without causing pollution. [0003] In recent years, the pollution of the earth's environment has become a worl...
