Detailed ways

First, refer to FIG. 1A . FIG. 1A is a schematic diagram of a display device 100 manufactured by applying the method of sticking polyurethane skin on a spherical surface of the present invention, wherein the display device 100 includes a display 1 and a spherical base 2 . Next, refer to FIG. 1B . FIG. 1B is an exploded view of the spherical base 2 in FIG. 1A , including a spherical plastic part 11 , a plurality of positioning strips 13 , and a plurality of leather pieces 12 . Wherein the material of the leather sheet 12 can be common polyurethane material, and can be made by cutting the leather with a knife die.

Next, refer to FIG. 1B and FIG. 2 at the same time. FIG. 2 is a partially enlarged view of the junction surface A of the spherical plastic part 11 and the leather sheet 12 of the present invention. As shown in Figure 2, the spherical plastic part 11 has a housing portion 111 for housing the skin 12, and the housing portion 111 has a bottom surface 111b and a side surface 111a, wherein the bottom surface 111b and the side surface 111a are preferably perpendicular to each other, so The leather sheet 12 can be accommodated more firmly.

Referring to FIG. 3, FIG. 3 is a flow chart showing the steps of the method for sticking polyurethane skin on the spherical surface of the display device of the present invention. Step S1 is to firstly provide the spherical plastic part 11, the positioning edge strip 13 and a leather part (for cutting into leather pieces 12). In this step, the material of the leather goods can be general polyurethane material. In addition, this step may also include the step of unfolding the leather item to release the stress deformation caused by the rolled up storage and transportation of the leather item.

Step S2 is a step of cutting the above-mentioned leather product to form the leather piece 12 , and the tool used for cutting the leather piece can be, for example, a knife die.

Step S3, thinning the edge of the skin 12. This step is to thin the edge of the skin 12 before pasting the skin 12 on the spherical plastic part 11, and reduce the thickness of the edge of the skin 12. Thinning, so that after the leather sheet 12 is pasted on the spherical plastic part 11, it can be aligned with the edge of the positioning edge strip 13.

Step S4 is the step of gluing the spherical plastic part 11 and the skin 12. This step includes: after evenly applying glue on the spherical plastic part 11, leaving it to a semi-dry state, and coating the glue on the skin 12 , baked to a semi-dry state, so as to avoid glue overflow when the leather product 12 is pasted on the spherical plastic part and pressurized in the subsequent steps; the above-mentioned baking temperature is preferably between 60 and 80 degrees. Step S5 is the step of adhering the positioning edge strip 13, wherein the positioning edge strip 13 can be pasted on the spherical plastic part by applying glue and then baking to a semi-dry state, or there can be a stick on the back for pasting. Adhesive for pasting. In addition, the width of the positioning edge strip 13 may be 6mm˜8mm.

Step S6 is the step of pasting the skin 12. When pasting the skin 12, first paste and fix the two ends of each side of the skin 12, and then press the edge of the skin 12 into the spherical plastic part with a needle 11 inside the side surface 111a of the receiving portion 111, so as not to cause poor flatness of the edge of the leather sheet 12.

Step S7 is the step of flattening the leather surface. Referring to FIG. 4, FIG. 4 shows a schematic diagram of the skin pressing device 3 used in the step of flattening the skin skin surface according to the present invention. The skin pressing device 3 includes an auxiliary supporting fixture 32 , a pressing device 33 and a soft pressing surface 34 for pressing up and down, wherein the auxiliary supporting fixture 32 can be, for example: a plastic soft ball, which is used to be inserted into the spherical base 2 pasted with the skin sheet 12 , to prevent the spherical base 2 from deforming under pressure; the soft pressurized surface can be made of soft materials such as rubber. Then, through the pressurizing device 33, the inside of the soft pressurized surface 34 is pressurized and poured into the fluid. The fluid can be, for example: oil or gas for pressurization, and pressurize the skin-applied surface through a staged pressurization method. To completely flatten and adhere to the skin sheet 12 surface. The purpose of segmental pressurization is to avoid displacement of the skin sheet 12 due to uneven stress caused by instantaneous high pressure on the plastic surface. In this example, a two-stage pressurization method is used to pressurize the leather surface, and the pressurizing pressure can be adjusted according to the actual situation (such as the material of the spherical plastic part), and is not particularly limited. Since the soft pressurized surface 34 is made of soft material, and the pressurization process is pressurized by fluid, it can achieve a good curved surface covering effect by virtue of the indeterminate nature of the fluid, and can evenly apply pressure to the spherical sticker. The good effect of fully pressing the leather surface and making it close to the spherical plastic part. In addition, the ball seat will not be damaged during the pressurization process.

Finally, referring to step S8 in the flow chart of Fig. 3, step S8 is the step of baking the finished spherical plastic part 11. The action of baking in the environment makes the bonded rubber surface react with heat to form a tight adhesion. After the above steps are completed, the positioning edge strip 13 and the leather sheet 12 are formed on the spherical plastic part 11 to form a basketball appearance. Therefore, through the method of sticking polyurethane skin on the spherical surface of the display device of the present invention, a novel display design that can be skinned on the spherical surface with unique appearance and touch can be developed.

Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the scope of the present invention. Any person skilled in the art may make some changes and modifications without departing from the scope of the present invention. The protection scope of the present invention What is defined by the scope of the claims and their equivalents shall prevail.
