Technical Field

The invention relates to the technical field of automatic paving and pasting of mosaics.

Background

The traditional process for producing the mosaic is to arrange scattered mosaic particles in a grid paved with mosaic moulding beds manually according to the same surface by a worker and then to glue the mosaic particles into a whole mosaic finished product by using a sticking material. Such manual operations result in inefficient and long labor time. Particularly, when mosaic particles with different colors are required to be paved into a mosaic finished product with a pattern, the positions of the mosaics with different colors in the pattern are required to be firstly marked according to the positions of the mosaics with different colors in the pattern, then the positions of corresponding lattices are marked on the paving mosaic forming dies, and then the mosaic particles with different colors are put into the lattices of the corresponding mosaic forming dies one by one. Therefore, the working difficulty is high, the labor force is occupied, and the production cost of the mosaic is increased.

Although some enterprises have been engaged in developing mosaic paving machines, the existing mosaic paving machines cannot automatically pave and pave mosaics with multi-color mosaics forming geometric patterns. In addition, the existing automatic paving and pasting equipment adopts a single production line to pave and paste the mosaic, so that multiple processes cannot be carried out simultaneously, the steps of the orderly paving and pasting process of one mosaic work are complex and long in time consumption, and the paving and pasting efficiency of the mosaic and the manufacturing efficiency of subsequent processes are affected.
