Example one

Referring to fig. 1, fig. 2 and fig. 7, an embodiment of the present invention provides a spherical patch, which includes a patch body 1, wherein the patch body 1 is a spherical sheet, and the side edges of a plurality of patch bodies 1 can be spliced together to form a sphere;

the side edge of paster body 1 is provided with the composition surface 101 that is used for carrying out the concatenation with the side edge of another paster body 1, and composition surface 101 is the arcwall face of evagination.

Specifically, the patch bodies 1 which are spliced with each other to form a sphere can be of the same specification, that is, the patch bodies 1 with the same size and shape are spliced to form a sphere, for example, the patch body 1 can be a quarter of a spherical surface, or other shapes which can be combined to form a sphere by using the same shape; still alternatively, the patch body 1 includes a plurality of differently shaped sheets, as well as pentagonal and hexagonal sheets. It should be known that, the side of the patch in the prior art is a plane, and when the adjacent patches are connected, the patch is bent from the plane to a spherical surface, and a certain deformation is generated, so that a gap occurs between the two patches.

This embodiment mainly used improves the inseparable degree of concatenation between two adjacent paster bodies 1 to promote the production yield of ball product and promote the surperficial aesthetic measure of ball product. Through setting up planar paster to spherical paster body 1 in this embodiment, can effectively avoid paster body 1 to produce too big deformation at subsides dress in-process. In addition, composition surface 101 is the evagination arcwall face, can effectively avoid producing darker V-arrangement opening between 1 between the composition surface of two mutual concatenations, has effectively promoted the inseparable degree of concatenation between two adjacent paster bodies 1, has promoted the outward appearance degree of ball product to be favorable to promoting the production yield of ball product. It is worth to be noted that, in the normal paster process, line contact (mutual contact between the arc surface and the arc surface) is formed between two adjacent paster bodies 1, and no gap is generated, but when the two adjacent paster bodies 1 have processing errors, the convex arc surface can deform to a certain extent when abutting against the other convex arc surface, so as to reduce the gap between the two adjacent paster bodies 1.

Furthermore, it will be appreciated that adjacent patch bodies 1 may be provided with shallow V-shaped grooves which reduce air resistance and positively affect the aerodynamic properties of the ball. It is worth noting that the V-shaped groove is deliberately designed to be much shallower than the V-shaped opening created by the prior art, and not to detract from the aesthetic appearance of the ball surface.

In this embodiment, the patch body 1 includes a skin protective layer 11 away from the center of the sphere and a soft elastic layer 12 close to the center of the sphere. It should be noted that the skin protective layer 11 is made of TPU (Thermoplastic Urethane elastomer) with a thickness of 0.02mm to 0.15mm, and the TPU has good elasticity and wear resistance, which is beneficial to increase the service life of the patch body 1. The soft elastic layer 12 is made of PU (Polyurethane), the PU has physical properties such as good elasticity and low hardness, and the thickness of the soft elastic layer 12 is 5-7 mm, so that the wear-resistant, high-elastic, light and soft environmentally-friendly patch body 1 is obtained. In particular, the soft elastic layer 12 can also be a PU microcellular foam layer to enhance its elasticity and softness.

In this embodiment, the patch body 1 further includes a hot-melt film layer 13 for thermally bonding the patch body 1 to the inflatable liner 2, and the hot-melt film layer 13 is located on the spherical surface of the soft elastic layer 12 on the side away from the skin protection layer 11. Specifically, this hot melt rete 13 is formed on the sphere of soft elastic layer 12 keeping away from one side of epidermis inoxidizing coating 11, need not to brush again when chip mounter paster, has promoted chip mounter's production efficiency.

It should be clear that the spherical patch is a sheet-like body integrally molded by a molding die.
