Description

Technical Field

[0001] The present invention relates to a cup body thermal transfer precision positioning jig; in addition, the present invention also relates to a cup body thermal transfer precision positioning method. Background Art

[0002] With the development of society and the advancement of technology, the requirements for product modeling and surface decoration are getting higher and higher. Thermal transfer is an emerging printing process. Thermal transfer processing uses a thermal transfer machine to transfer the exquisite pattern on the transfer film to the surface of the product in one process (heating and pressurizing). After molding, the ink layer and the product surface are integrated, which is realistic and beautiful, greatly improving the grade of the product. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing adopts dot printing (resolution up to 300dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color difference and good reproducibility. It can achieve the required design effect and is suitable for mass production.

[0003] The popular stainless steel thermos cups pursue individuality and brand influence. The outer surface of the cup body is no longer the cold stainless steel original color or a simple color coating, but is decorated with trademark logos and various design patterns. Especially for stainless steel thermos cups and thermos bottles for infants and young children, the surface of the cup body is designed with various cartoon patterns to achieve the purpose of appearance decoration to attract users. At present, the decorative pattern of the round cup body of this stainless steel thermos cup is achieved through processes such as thermal transfer, screen printing, drape water transfer, and pad printing. If the design is highly accurate, the pattern is rich and bright in color, and the overall continuity of the cup body is required, the thermal transfer process is mainly used. The main reason is: the thermal transfer printing film is made by gravure printing technology. The gravure printing process is characterized by bright and rich colors. The printing can reach eleven colors, and all color processes are completed in one go; it can print very delicate and clear text and spot color effects, and can also print high-resolution images and pictures.

[0004] However, there is still a flaw in the thermal transfer of stainless steel thermos cups, which is that it is difficult to accurately position the thermal transfer. For example, the product design requires printing a specific trademark logo on the body of the stainless steel thermos cup, and requires that after the cup lid is installed and tightened, the cap on the cup lid and the trademark logo on the cup body must be in the same straight line corresponding to the central axis, and maintain the stability of mass production. It is very difficult for the current process technology to meet the above requirements, mainly for the following reasons:

[0005] First, the processing technology characteristics of the stainless steel thermos cup body are that the stainless steel thermos cup body is divided into an "inner cup liner", an "outer cup shell" and a "bottom cover". These three parts are completed by laser welding, so the relative positions of each part are difficult to guarantee. It cannot be formed in one step through mold injection or blow molding like plastic products, and a printing process positioning mark is reserved on the bottom.

[0006] Second, there are tolerances in the processing of stainless steel thermos cups in each process. The cup lid is a plastic product, and the stainless steel thermos cups for infants and young children are also designed with plastic handles. The cup mouth threads, handles, and cup lid each have tolerances. The cup lid, handles, and cup body are assembled together, and the cumulative tolerance is even greater. In this way, even if the cup body can be preset during processing and the printing process positioning mark is reserved on the bottom of the cup body, after the lid, handle and cup body of the stainless steel thermos cup are assembled, the cumulative tolerance is too large to achieve consistency between the cup lid cap and the cup body trademark logo. Therefore, the printed pattern cannot be accurately positioned, and mass production is impossible. Summary of the invention

The positioning process is moved back, and the positioning point is used as the printing point during subsequent thermal transfer. The positioning point can be accurately printed, avoiding the positioning deviation caused by the reserved positioning mark in the process of cup body production, so that the precise positioning position is guaranteed to be consistent with the positioning position after the cup cover and handle are installed when the cup is in normal use. Therefore, the cup body thermal transfer precise positioning fixture of the present invention has accurate positioning, is easy to implement and mass produce, and has a high product qualification rate; similarly, the cup body thermal transfer precise positioning method of the present invention can accurately position the printed pattern, which makes the cup body more decorative and has a stronger brand effect, so that the trademark logo is always printed at the set position on the cup body and maintains batch consistency.
