Intelligent manufacturing control system for whole solar cell factory

Abstract

The invention discloses a solar cell whole plant intelligent manufacturing control system, and the system comprises a control unit, an AGV unit and a plurality of control stations; the control stations respectively correspond to different process sections, namely a texturing control station, an annealing control station, a secondary cleaning control station, a diffusion control station, a code control station, a PECVD control station and a screen printing control station; each control station is an independent control station and independently supplies power, and the control stations are linked with one another and are connected with the control unit to form a looped network; the AGV unit is connected to the looped network, and the control unit controls an AGV in the AGV unit to carry outmaterial taking and feeding operation among all process sections. The system has the advantages of being high in automation and intelligence degree, high in production efficiency, safe, reliable and the like.

Description

technical field [0001] The invention mainly relates to the technical field of solar cell production, in particular to an intelligent manufacturing control system for a solar cell whole plant. Background technique [0002] The mid-stage production of solar cells includes multiple process stages, such as: texturing, annealing, secondary cleaning, diffusion, plate PECVD, tubular PECVD, laser screen printing and other processes. Each process is interconnected and is the upstream and downstream of each other. The entire production process is: texturing→annealing→secondary cleaning→diffusion→plate PECVD→tubular PECVD→laser screen printing→testing and sorting. [0003] In the past, the feeding and discharging of the equipment in the process section of the workshop were carried by hand, which had the following technical disadvantages: manual loading and unloading was time-consuming, laborious, and low in production efficiency. If it is wrong, the output of the previous process will...

Problems solved by technology

[0003]In the past, the feeding and discharging of the equipment in the process section of the workshop were carried by manual flower baskets, which had the following technical shortcomings: manual loading and unloading was time-consuming, laborious, and low production efficiency , Sometimes when manual loading and unloading is carried out at night, there will be a big mistake, and the output of the previous process will be mistakenly taken to the next process equipment for process treatment, causing irreversible damage to the solar cells

But there are still the following deficiencies: the automatic solution of mesh belt transmission or high-altitude mesh belt transmission will block the water around the entire workshop, which will bring great inconvenience to personnel walking, and at the same time, the aesthetics of the workshop will also be greatly reduced

In addition, like the high-altitude conveyor belt, there is a risk of falling and hurting people. When the equipment fails, it is very inconvenient to handle.
