An automatic leveling device and leveling method for solar module eva laying

Abstract

The invention discloses an automatic leveling apparatus and leveling method for EVA pavement of a solar module. The automatic leveling apparatus comprises a basic framework and a first leveling roller and a first leveling roller which are arranged at the front end and the back end of the top of the basic framework respectively, wherein the first leveling roller and the second leveling roller are in mutual parallel in a horizontal direction; the basic framework is adjustable in height; multiple transverse grooves are formed in the first leveling roller while multiple longitudinal grooves are formed in the second leveling roller; and the transverse grooves and the longitudinal grooves both adopt linear structures, and are vertical mutually. By setting the two leveling rollers front and back, and by enabling the grooves in the two leveling rollers front and back to be distributed at an angle of 90 degrees, the leveling effect and the anti-skidding effect are better compared with a single planar leveling roller; meanwhile, manpower and material resources are reduced in the production process and the efficiency is improved; and in addition, the automatic leveling apparatus is simple and convenient to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of solar cell module production tools, in particular to an automatic leveling device and a leveling method for laying solar module EVA. Background technique [0002] Solar module encapsulation is the core technology of the entire module manufacturing industry. It is laminated in the order of tempered glass, EVA, battery string, EVA, and backplane to ensure that the core component battery sheet is cushioned by double-layer EVA material. , plus the tempered glass on the front and the back plate material on the back greatly enhance the impact resistance and aging resistance of the module. [0003] In the solar module packaging process, in the EVA laying process after the tempered glass is loaded, due to the large-area EVA wrinkles and unevenness caused by the EVA automatic laying process, it is easy to cause the positioning accuracy of the battery string laying and the laying of a large number of batteries in t...

AI Technical Summary

Problems solved by technology

[0004] At present, the mainstream EVA laying process in the solar module manufacturing industry is the automatic cutting + laying process. The cut EVA is automatically laid on the tempered glass surface by a mechanical gripper or suction cup through a pre-programmed path and precise positioning. During the laying process, EVA is easy to cause Surface wrinkles, EVA unevenness, and EVA and tempered glass quality inspection have air bubbles and protrusions. When the battery string is laid in the subsequent laying process, it is easy to cause the battery chip to break or increase the probability of hidden cracks, which may directly lead to the after-lamination. The overall displacement of the components and the spacing between the strings are not good, which may seriously lead to the short-circuit and scrapping of the components caused by parallel strings, reduce the pass rate of finished components, increase the process manufacturing cost and material consumption, and affect the company's overall production and operation costs
