A fully automatic solar heating strip laser welding production process

Abstract

The invention discloses a full-automatic solar energy heat collecting strip laser welding production process. The full-automatic solar energy heat collecting strip laser welding production process comprises the following steps that step 1, pipe pieces are straightened and cut by a straightening machine to obtain pipes with required sizes, and metal strip pieces are flattened and cut by a flattening machine to obtain plates with required sizes; step 2, the pipes and the plates are assembled and matched in an automatic pipe plate conveyor; step 3, the pipes and the plates assembled on the automatic pipe plate conveyor are transferred on an automatic laser welding input machine; step 4, a group of pipes and plates on the automatic laser welding input machine is transferred to an automatic laser welding machine for welding to obtain heat collecting strip assemblies; step 5, the heat collecting strip assemblies is transferred out of the automatic laser welding machine by the automatic laserwelding output machine; step 6, the automatic laser welding output machine transfers the heat collecting strip assembly to an automatic surface-turning-over stacking and packaging machine for turning-over of surfaces and stacking; and step 7, after the stacked heat collecting strip assemblies is automatically packaged by an automatic winding machine, the stacked heat collecting strip assemblies enter a conveyor belt device for output.

Description

technical field [0001] The invention relates to a fully automatic solar energy heating strip laser welding production process. Background technique [0002] At present, aluminum sheets and pipes are widely used as heat collecting plates in flat solar water heaters. The traditional heat collecting plates sandwich a pipe between two layers of aluminum sheets and flatten them to make the copper and aluminum bond tightly. After surface coating The pre-flattened tubing is blown into shape using high-pressure water or compressed air. However, the traditional heat collector only has two layers of pressure-bearing materials, aluminum sheets and pipes, and the pipes are rolled and inflated, and the bending parts will be damaged to a certain extent. The pressure-bearing limit is low, and it is suitable for places with low water supply pressure. In the production process, the scrap rate is high and there are hidden dangers. Some solar water heater companies have proposed new collecto...

Problems solved by technology

The heat collector with this structure has only one layer of pressure-bearing material, and its pressure-bearing capacity is limited, and because the fins and heat collector tubes are rolled by a rolling mill, the contact between the two is not close, which will affect the heat transfer efficiency
