Description

A method for marking the frame of a photovoltaic module and a production process for the photovoltaic module

technical field

The invention relates to a method for marking a frame of a photovoltaic module and a production process thereof, belonging to the technical field of photovoltaic module production.

Background technique

At present, the world's photovoltaic power generation industry has developed rapidly since the 1980s, with an average annual growth rate of 30%, and has become one of the fastest growing high-tech industries in the world. Solar photovoltaic technology is receiving widespread attention because of its clean energy. At present, there are many module serial numbers and nameplates on traditional photovoltaic modules to facilitate production process control and customer reference, but most of the serial numbers and nameplates used today are printed on artificial paper and pasted on the back of the module or laminated on the module. In order to achieve the purpose of information recording and tracking, the current traditional module process operation process is shown in Figure 1. The serial number is generated in the system and printed out. In the stacking section, the serial number is pasted on the bus bar and laminated The process is pressed into the module; after subsequent power and EL tests, the serial number and module nameplate are pasted on the backplane again. This operation not only wastes manpower and cost, but is also not conducive to environmental protection. The serial number and nameplate may be damaged or lost, and the paper serial number clamped in the component is not only unsightly, but as time goes by, the serial number here may be difficult to scan when the component is in a complex external environment, serious There may also be potential reliability risks.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a method for marking the frame of a photovoltaic module. This method saves procedures, saves manpower and cost, is beautiful and elegant, and the relevant information prepared can still be scanned and read after a long time , high reliability.

In order to solve the above technical problems, the technical solution of the present invention is: a method for marking the frame of a photovoltaic module, which integrates the company trademark information, the serial number information of the photovoltaic module and the nameplate information of the photovoltaic module into an integrated design, and inputs it into the marking equipment to mark Outside the effective area of the photovoltaic module, it does not affect the performance and appearance of the photovoltaic module on the profile of the photovoltaic module.

Furthermore, the said marking equipment is a laser laser machine, which adopts laser technology to mark the information of the integrated design on the profile of the photovoltaic module.

Further, the serial number information of the photovoltaic module includes one-dimensional code information and/or two-dimensional code information.

The invention also provides a photovoltaic module production process, which uses the photovoltaic module profile obtained by the method for marking the frame of the photovoltaic module to prepare the photovoltaic module.

The present invention also provides another photovoltaic component production process, which also adopts the marking method for the frame of the photovoltaic component, and the marking method is located between the finished EL testing process of the photovoltaic component and the packaging process of the finished photovoltaic component.

After adopting the above technical solution, the present invention cancels the traditional paper template and operation method as shown in Figure 1, and only needs to use one-step engraving, all relevant information of photovoltaic modules (company trademark information, photovoltaic module serial number information and photovoltaic module information) Module nameplate information, etc.) can be printed on the photovoltaic module profiles at one time, and laser scanning can be realized to read relevant information. This method is not only beautiful and environmentally friendly, saves procedures, labor and costs, but also greatly enhances its ability to resist the external environment , the prepared relevant information can still be scanned and read after a long time, with high reliability.

detailed description

In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

Embodiment one

As shown in Figure 2, a photovoltaic module production process, the steps of the process are as follows:

(1) Welding;

(2) lamination;

(3) Defect (EL) test;

(4) lamination;

(5) framing;

(6) Silicone curing and cleaning;

(7) Pressure test;

(9) Finished product EL test;

(10) Relevant information engraved on the profile: adopt the marking method of the photovoltaic module frame of the present invention;

(11) Packaging process of finished photovoltaic modules.

Among them, the steps of the marking method for the frame of the photovoltaic module are as follows: design the company trademark information, the serial number information of the photovoltaic module, the nameplate information of the photovoltaic module and other related information in an integrated manner, and input it into the marking equipment, and mark it outside the effective area of the photovoltaic module. On the profiles of photovoltaic modules that affect the performance and appearance of photovoltaic modules.

The marking equipment is a laser laser machine, which uses laser technology to mark the information of the integrated design on the profile of the photovoltaic module, but is not limited to this.

The serial number information of the photovoltaic module may also include one-dimensional code information and/or two-dimensional code information.

Embodiment two

The steps of a method for marking the frame of a photovoltaic module are as follows: design the company's trademark information, the serial number information of the photovoltaic module, the nameplate information of the photovoltaic module and other related information in an integrated manner, and input it into the marking device, and mark it outside the effective area of the photovoltaic module. On the profiles of photovoltaic modules that affect the performance and appearance of photovoltaic modules

A photovoltaic module production process, the profile supplier directly supplies the photovoltaic module profile with relevant information obtained through the method of marking the frame of the photovoltaic component, and uses the photovoltaic component profile for conventional production and assembly of the photovoltaic component.

The working principle of the present invention is as follows:
