Surface heat-transferring system and heat-transferring method

Abstract

The invention discloses a surface heat transfer printing system, comprising a heat transfer printing device, a workpiece positioning device, an induction device and a transfer printing paper supply device. The heat transfer printing device comprises a heat transfer printing platform used for holding the workpiece for heat transfer printing and a heat transfer printing actuator use for carrying out the heat transfer printing process. The workpiece positioning device is arranged on the heat transfer printing platform and is used for fixing and arranging the workpiece for heat transfer printing. The induction device is arranged on the upper part of the heat transfer printing platform and is used for sensing the adhering position information of the transfer printing paper when the transfer printing paper is glued. The transfer printing paper supply device is positioned at one side of the workpiece positioning device and is used for supplying the transfer printing paper to the surface of the workpiece fixed on the workpiece positioning device for heat transfer printing. The invention also discloses a surface heat transfer printing method.

Problems solved by technology

Generally, the method of pasting the transfer paper on the surface of the workpiece is to apply glue on the surface of the workpiece first, and then manually paste the transfer paper on it, which is very time-consuming, especially in pasting. When applying transfer paper, it must be ensured that the transfer paper and the surface of the workpiece to be transferred can be completely adhered to. Manually pasting the transfer paper often results in that the transfer paper and the surface of the object to be transferred cannot be completely adhered to, resulting in The color patterns transferred on the surface of the workpiece are misplaced and discontinuous, resulting in defective workpieces and affecting the thermal transfer quality of the workpieces

In addition, in terms of pattern position accuracy requirements, the common thermal transfer printing technology used in the industry has great limitations in production accuracy requirements. Multi-color positioning is difficult, easy to cause deviation, and the product yield is low. It is not suitable for portable Thermal transfer requirements for high-precision patterns on the surface of electronic devices and other housings
