Soft and hard material combined seal with cast electronic chip and manufacturing method of seal

Abstract

The invention provides a soft and hard material combined seal with a cast electronic chip and a manufacturing method of the seal. The seal and the manufacturing method aim to solve the problems that an electronic chip in the prior art cannot be clearly and directly displayed on a seal, and the advantages and disadvantages of a hard seal and a soft seal cannot be complementary. According to the technical point, the seal comprises a seal body, an electronic chip assembly and a seal face; the seal is characterized in that the seal body is a hard transparent body, an axial inward concave part is formed in the lower end surface of the seal body, and a radial inner concave annular groove is formed in the wall portion of the inward concave part; and the electronic chip assembly is fixed to the middle position of the inward concave part, the inward concave part is filled with a soft transparent body, the end face, protruding out of the lower end surface of the seal body, of the soft transparent body is a plane and forms the seal face of the seal, the hard transparent body is made by PC or MBS material injection molding, the soft transparent body is made by TPU material injection molding, the middle of the inward concave part is coated with adhesive through a mechanical arm, and then the electronic chip assembly is placed in the inward concave part through the mechanical arm and adheredto the adhesive.

Description

technical field [0001] The invention relates to a stamp that needs to be stained with paint and then stamped and a manufacturing method thereof, in particular to a stamp combined with soft and hard materials containing an electronic chip and a manufacturing method thereof. Background technique [0002] At present, the commonly used seals need to be stained with paint and then stamped. There are hard seals made of jade, metal, wood, stone, hard plastic, etc., and soft seals made of rubber, soft plastic, etc. The body and the chapter surface are generally formed from the same material. Among them, the degree of deformation of the printed text of the hard seal is small, but the flatness of the paper surface has a greater impact on the quality of the printed text; the quality of the printed text of the soft seal has good adaptability to different flatness of the paper surface, but the degree of deformation of the printed text is relatively large. Moreover, if the body or the ha...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the fact that the electronic chips in the existing electronic chip stamps cannot be clearly and correctly displayed on the proper position of the stamp, a strong new aesthetic feeling for the traditional stamp is formed, and the hard surface that needs to be stained with paint and then stamped The advantages and disadvantages of seals and soft seals cannot complement each other. The purpose of this invention is to provide an improved soft and hard material combined with stamps with electronic chips and its manufacturing method, which can overcome the defects of the prior art.
