Photovoltaic module three-code automatic verification method

Abstract

The invention discloses a photovoltaic module three-code automatic verification method. The photovoltaic module three-code automatic verification method comprises the following steps A, after a moduleis transferred to a three-code verification station through an assembly line, a photoelectric induction switch triggers a restoration mechanism to perform positioning and fixing on the module position; B, meanwhile, three code-scanning guns scan bar codes of the corresponding position at the same time, and transmit the bar code information to a communication module and a control program module ina PLC controller separately; and C, after the communication module and the control program receive the bar code information, an analysis system takes 3-5 seconds to perform bar code information comparison. The verification method disclosed in the invention is simple and capable of replacing manual examination and verification, avoiding leak detection, realizing 100% of examination and verification and ensuring unification of three codes of each module, meanwhile, improving operational automation, saving manpower, improving operation efficiency and achieving an excellent verification effect.

Description

technical field [0001] The invention relates to the technical field of barcode verification, in particular to a three-code automatic verification method for photovoltaic modules. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, and send it to the storage battery for storage, or to drive the load to work; however, with the use of the micro-inverter, the current source of the photovoltaic module can be directly converted into a voltage source of about 40V. It can drive electrical appliances in our life; at the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called Chinese manufacturing in the industry, they should be created in China, and then there are upgraded and innovative products of photovoltaic modules, such as photovo...

Its function is to convert solar energy into electrical energy, and send it to the storage battery for storage, or to drive the load to work; however, with the use of the micro-inverter, the current source of the photovoltaic module can be directly converted into a voltage source of about 40V. It can drive electrical appliances in our life; at the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called Chinese manufacturing in the industry, they should be created in China, and then there are upgraded and innovative products of photovoltaic modules, such as photovoltaic ceramic tiles and photovoltaic color steel. Tile, this kind of product can directly replace traditional building material tiles, and has the function of photovoltaic modules. Once it enters the general market, it will have a certain impact on photovoltaic modules and traditional building materials.

[0003] In the manufacturing process of photovoltaic modules, three barcodes need to be pasted on the glass surface, the back panel surface and the frame respectively, and these three barcodes must be consistent. For the sake of convenience, only check the barcodes on the back panel and frame, and neglect the inspection on the barcodes on the glass surface, and the manual inspection is easy to miss, and it is impossible to guarantee all inspections, which wastes manpower, low operating efficiency, and poor results.
