Description

Technical Field

[0001] The utility model relates to the technical field of hand-plate models, and in particular to a quick skin and film pasting device for a hand-plate model. Background Art

[0002] A prototype is one or more functional prototypes, created based on a product's appearance or structural drawings before a mold is created. These prototypes are used to verify the appearance or structural rationality of a product. Typically, newly developed or designed products require prototypes. Prototypes are the first step in verifying product feasibility and the most direct and effective way to identify flaws, deficiencies, and shortcomings in a product design, allowing targeted improvements until no flaws can be found in individual prototypes. Therefore, to accurately verify design proposals, the appearance of the prototypes is generally highly demanding, especially for electronic products and valuables. To achieve this, a protective film or leather tape is often applied to the surface of the prototype. However, purely manual film and leather application methods are far from meeting productivity requirements. Furthermore, manual production often compromises product quality and appearance due to poor technique and lack of proficiency, resulting in problems such as film offset and bubbles within the film.
