Rolling equipment and method for solar photovoltaic welding strip tinning machine

Abstract

The invention discloses rolling equipment for a solar photovoltaic welding strip tinning machine. The rolling equipment comprises a wire storing device, a rolling control system and a rolling device which is controlled by the rolling control system and connected with the wire storing device, wherein a welding strip is rolled by the rolling device after passing through the wire storing device. Therolling control system disclosed by the invention further comprises a rolling control device and a wire arrangement control device which are respectively used for controlling the welding strip to roll in the radial direction of a wire rolling disc and controlling the welding strip to be arranged in the axial direction, so that the rolling equipment disclosed by the invention can be used for rolling all large / small wire rolling discs. The invention further discloses a rolling method using the equipment. The rolling method comprises the following steps of: detecting the state of the rolling device; if the rolling device is in a pause state, turning on the wire storing device; and otherwise, selecting different wire arrangement control manners according to the rolling weight so that the rolling device rolls by means of being compatible with a large roll and a small roll. According to the rolling equipment and method disclosed by the invention, a tinning wire has no need of being stopped in a full roll condition; and the rolling device can be randomly turned off in a short time to replace the wire rolling disc and / or detect the quality and thickness of the surface of the wire rolling disc in an on-line manner.

Description

technical field [0001] The invention relates to a winding device and a winding method, in particular to a winding device and a winding method of a solar photovoltaic solder ribbon tin plating machine. Background technique [0002] Solar photovoltaic ribbon is an important material for connecting crystalline silicon cells and conducting electricity on solar modules. With the rapid development of the solar power generation industry, the quality requirements for solar modules are getting higher and higher, and more and more solar photovoltaic modules are used. Manufacturers are transitioning from traditional manual welding to automated mechanical welding. Automatic mechanical welding has high requirements on the straightness, winding quality and yield strength of the welding strip, and it is difficult for the traditional welding strip production process to meet the above requirements.

AI Technical Summary

Problems solved by technology

Automated mechanical welding has high requirements on the straightness, winding quality and yield strength of the welding strip, and the traditional welding strip production process is difficult to meet the above requirements

[0003] like figure 1 As shown, the traditional welding strip production process adopts a single-machine multiple slow-speed tinning method. The welding strips pass through the unwinding equipment 1, the tinning equipment 2, and the winding equipment 3 one by one. The working speed is 3-5 m / min. The machine not only occupies a large area, but also has low production efficiency and unstable product quality. The maximum shift output of a single machine is only 50 kg

The winding weight of the ordinary straight-edge reel used in the winding equipment is about 4-5 kg. During the subsequent working process of the automatic welding machine and automatic cutting machine, it will cause frequent roll changes and low production efficiency.

At the same time, unpredictable vibrations during transportation can easily lead to problems such as uneven side seams and twisted belts on the ribbon wound on the straight-sided reel, which will affect the use efficiency and increase the potential danger of the product.

In severe cases, it may even directly cause battery fragments, causing economic losses to customers

[0004] When the rewinding stops when the ordinary tinning machine is in operation, it is inevitable that there will be a solder scar at the root of the tinned soldering strip. During the tinning production process, the tinned soldering strip cannot be stopped for detection

Cells in the solar photovoltaic industry require automatic welding and no scarring is allowed. A special winding device is required to manually remove the scarring after rewinding.

The tinning line must be stopped after full volume, and the winding device cannot be restarted in a short time

Low production efficiency
