Photovoltaic module turnover vehicle

Abstract

The invention discloses a photovoltaic module turnover trolley which belongs to the equipment field of specially handling semi-conductor elements and solves the problems that the present turnover trolley has a complex lifting structure and high energy consumption. The photovoltaic module turnover trolley comprises a base and a vertical bracket fixed on the base; moving wheels are arranged below the base; the vertical bracket comprises a vertical plate and upright support columns I; horizontal support layers are fixed on the vertical plate; one upright support column is respectively arranged at two ends of the vertical plate; springs are fixed at the bottoms of the upright support columns I; support rods are arranged at the lower side of the horizontal support layer at the bottommost layer; the support rods comprise transverse rods and upright support columns II; and springs II are arranged in the upright support columns II. The turnover trolley has a simple structure and does not need a special power unit; the investment and maintenance cost can be saved, the automatic rising and descending can be realized and operators can pick and place laminated modules conveniently.

Description

technical field [0001] The invention relates to a kind of equipment specially used for processing semiconductor devices, in particular, relates to a turnover car for photovoltaic modules. Background technique [0002] Solar cell modules need to go through a lamination process in the production process. The lamination process is to layer glass, hot melt adhesive film, cell array, hot melt adhesive film, and back sheet materials in sequence, and then send them into a laminating machine to press them into one. process. Before lamination, the glass, hot-melt adhesive film, cell array, hot-melt adhesive film, and backsheet materials need to be stacked in sequence, and then transported to the laminator for lamination. Materials such as cells and glass are easy to turn over during the turnover process. Damage is caused, and the efficiency of single-piece turnover is low. For this reason, turnover vehicles are often used for multi-piece turnover. [0003] The existing turnover car...

AI Technical Summary

Problems solved by technology

[0003] The existing turnover car structure is to set multi-layer horizontal brackets from top to bottom, and the horizontal brackets are fixed on the vertical brackets. In order to make the stacked components transported as many as possible, the structure is equipped with multi-layer horizontal brackets. Therefore, the horizontal brackets The height is high. When in use, only a few floors are suitable for taking and placing stacked components. The stacked components on other horizontal supports are either higher than the operator's comfortable working height or lower than this height. Take and place components More inconvenient, resulting in reduced work efficiency

At the same time, when taking out the stacked components on the lower layer, it is necessary to bend down. Due to the limited vision, the stacked parts are easy to touch the supporting structure wall, which poses a certain danger to the safety of the stacked parts.

[0004] The date of announcement is September 21, 2011, the application number is 201020690912.3, and the invention patent titled "liftable and automatic unloading stacked parts turnover car" discloses a stacked parts turnover car that uses a hydraulic device to realize the lifting function. The turnover car has a relatively complex structure, uses hydraulic power, high energy consumption, and high cost. The most critical problem is that the turnover car cannot realize automatic lifting, and manual control of the hydraulic mechanism is required to realize the rise and movement of the horizontal support on the turnover car.

Even if the rate of rising and falling of the horizontal support is controlled by setting a program, it will deviate from the work efficiency of the operator. For example, when the operator is tired and needs to rest, the horizontal support is still in the process of rising. This structure requires external force Achieve ascent and descent, and there is a certain deviation from the operator's work habits or efficiency
