Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging, and in particular relates to a packaging device for a photovoltaic component. Background Art
[0002] In the process of preparing photovoltaic modules, it is often necessary to punch holes on the cover glass or front glass of the photovoltaic modules to pass the busbar through the module and connect it to the junction box. Since photovoltaic modules have high requirements for water and oxygen, if the glass hole where the busbar passes through is not sealed during the DH aging test, the sealing effect cannot be achieved by simply relying on potting glue.
[0003] The commonly used sealing method now is to fill the glass hole with UV curing glue or butyl glue. UV curing glue can be filled by dispensing. Since butyl glue is solid at room temperature, it is difficult to plug the hole by dispensing or extrusion. It is usually done by manually filling butyl glue particles / balls into the glass hole. The disadvantages of this manual filling method are slow speed and poor repetition accuracy. In addition, the melting point of butyl glue exceeds 180 degrees. After filling and lamination, it is difficult to ensure that the melted butyl glue can fill the entire glass hole, and it is difficult to ensure that the butyl glue is tightly combined with the glass hole wall. It is also difficult to ensure that there is no air / water vapor in the butyl glue. Utility Model Content

[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0012] Please refer to Figure 1 As shown, a preferred embodiment of the packaging device of the photovoltaic module of the utility model includes a packaging glue supply component 1, a vacuum component 2 and a vacuum chamber 3.
[0013] The packaging glue supply assembly 1 includes a packaging glue container 11 containing packaging glue, a packaging glue valve 12 and a packaging glue pipeline 13. The packaging glue valve 12 is arranged on the packaging glue pipeline 13. One end of the packaging glue pipeline 13 is connected to the packaging glue container 11, and the other end of the packaging glue pipeline 13 extends into the vacuum chamber 3, and a glue dropper 14 is arranged at the end.
[0014] The vacuum assembly 2 includes a vacuum pump 21, a vacuum valve 22, a vacuum pipe 23 and a vacuum pressure gauge 24. One end of the vacuum pipe 23 is connected to the vacuum pump 21, and the other end of the vacuum pipe 22 is connected to the vacuum chamber 3. The vacuum valve 22 and the vacuum pressure gauge 24 are respectively arranged on the vacuum pipe 23.
[0015] An opening is provided on one side of the vacuum chamber 3, and a sealing ring 4 is provided at the edge of the opening. The area where the surface of the photovoltaic module A contacts the sealing ring 4 forms a sealing area, and a to-be-encapsulated area B is provided in the sealing area, and the glue dispensing head 14 is located directly above the to-be-encapsulated area B.
[0016] The packaging glue is butyl glue, and a heater (not shown in the figure) for heating and melting the butyl glue is arranged on the packaging glue container 11.
[0017] There is a groove or a junction box to be packaged in the to-be-packaged area B. The glue dispensing head 14 performs glue dispensing on the groove or the junction box to be packaged.
[0018] The method of using the packaging device of the photovoltaic module of the utility model is:
[0019] 1) First, the butyl rubber in the packaging rubber container 11 is heated by a heater to melt it, and the following steps are started after the temperature reaches a stable 180°C.
[0020] 2) Clean the sealing area of the photovoltaic module A and the glass surface around the glass hole in the area to be packaged B with anhydrous ethanol, and fit the vacuum chamber 3 to the sealing area of the glass surface.
[0021] 3) Turn on the vacuum pump 21, open the vacuum valve 22, and when the pressure value in the vacuum chamber 3 reaches below 100 Pa, close the vacuum pump 21 and the vacuum valve 22. The sealing ring 4 is sealed against the glass surface of the photovoltaic module A.
[0022] 4) Open the packaging glue valve 12. The butyl glue in the packaging glue container 11 has been heated to a fluid state. Under the vacuum suction of the vacuum chamber 3, the butyl glue will quickly fill the entire packaging area B without bubbles and water vapor. After completing the above actions, close the packaging glue valve 12.
[0023] 5) After the temperature has cooled, the vacuum chamber 3 and the photovoltaic module A are separated.
