Problems solved by technology

However, if the height of the workpiece is high, problems such as large drawing angle, uneven stretching, and stacking of the appearance film will often occur during processing.
The stretching degree of the appearance film on the side of the workpiece with a large height is quite different from that on the front. The stretching degree of the appearance film on the front is relatively small, while the stretching degree of the appearance film on the side is relatively large, resulting in uneven stress distribution of the appearance film. , prone to shrinkage and uneven thickness
Moreover, when the workpiece is wrapped, more materials will be piled up at the corners, which is difficult to cut, and even the overall appearance of the workpiece will be damaged, which will affect the overall performance of the appearance film.

Abstract

The invention provides a method for covering an appearance film on the surface of a workpiece, a workpiece product, a household appliance and a mould. The method for covering the appearance film on the surface of the workpiece comprises the steps that 10, the appearance film covers the surface of the mould through a vacuum blister process; 20, the appearance film is separated from the mould, and the appearance film forms a prefabricated appearance film; and 30, the prefabricated appearance film covers the workpiece surface through the vacuum blister process. According to the method for covering the appearance film on the surface of the workpiece, firstly, the appearance film is preformed, and the appearance film covers the mould through the vacuum absorbing process, wherein the height of the appearance film is similar to and slightly greater than the height of the workpiece; and then the prefabricated appearance film covers the adhesive workpiece through the vacuum absorbing process, and meanwhile, the situation the first appearance film surface of the prefabricated appearance film cannot be stretched because the first appearance film surface is pasted onto the workpiece firstly, and excessive stretching of the second appearance film surface is caused does not happen.

Description

technical field [0001] The invention relates to the field of household appliances, more specifically, to a method for coating an appearance film on the surface of a workpiece, a workpiece made by the method, a household appliance including the workpiece, and a mold used in the method. Background technique [0002] At present, in the home decoration industry, the appearance of many wooden products is realized by vacuum blister technology, that is, the appearance film is decorated on the workpiece through vacuum blister, so that the workpiece can achieve various appearances that consumers like, and increase the premium level of the product. At present, many home appliances are gradually showing the appearance of vacuum blister. However, if the height of the workpiece is high, problems such as large draw angle, uneven stretching, and stacking of the appearance film will often occur during processing. The stretching degree of the appearance film on the side of the workpiece wit...
