In general, several electronic devices, such as smartphones, tablet PCs, etc., are covered with protective films to prevent scratches on the glass surface, which displays the screen.

Some problems, such as bubble generation and defects, often occur as the protective film’s position is nonuniform, inaccurate, and not applied using techniques that would ensure airtight attachment on curved parts of devices.

Hence, the protective film attaching apparatus has been invented to solve these problems.

Quality differences depend on the skills of sales clerks, who conventionally and manually attach protective films in smartphone stores.

As such, various problems surface, and many improvements are required.

Bubble generation, film position warpage, difficulties in attaching the film on the smartphone’s edges, quality differences, and the mixture of foreign materials are some of the common issues encountered when reworking the attachment.

Thus, our company has developed a protective film attaching machine that enables the production process to be performed through one cycle of the rolling process, which simultaneously attaches the protective film to the smartphone’s flat surface and edges.

This technique has been used by Samsung Electronics Co., Ltd. for business-to-business (B2B) in large quantity production.

The core techniques of our company’s protective film attaching apparatus include replacement correspondence per model through cartridge correspondence and film seating and attachment through attachment speed and predetermined elasticity maintenance according to the liquid crystal protective film’s material.
