Golf ball manufacturing method and product thereof

The present invention relates to a method of manufacturing a golf ball and a product thereof, and more particularly to a method of manufacturing a golf ball filled with a wafer module and a battery, and an article thereof.

With the continuous advancement and miniaturization of sensing modules and communication technologies, technologies for real-time positioning and information measurement using wafer modules have been widely used in various fields. For example, when playing golf, if the sensing module or communication module can be assembled in the golf ball, the speed and position of the golf ball can be instantly grasped, which not only helps the player in the weather or the field of vision is not good. Understand the flight path of the golf ball that you have shot, and also find the location of the golf ball in a vast and complex venue. Even some chip modules have built-in buzzer and other prompting devices. When people approach, they will make a sound or other prompts to help people find the ball in the grass or the leeches.

Due to the increasing versatility of the chip modules, many of the chip modules need to be battery-driven to obtain sufficient power to maintain normal operation. Therefore, when the wafer module is enclosed in the golf ball, the chip module is also electrically connected at the same time. The battery is sealed together. However, the aforementioned golf ball is manufactured by hot press forming, and the molding temperature often reaches 150 degrees Celsius or more. Therefore, in the manufacturing process, the battery which is not resistant to high temperature is easily damaged due to direct contact with the high temperature plastic fluid, and may also be mutated. Damage to the wafer module affects normal operation.

Accordingly, it is an object of the present invention to provide a method of manufacturing a golf ball that protects a battery and a wafer module.

Thus, the method of manufacturing the golf ball of the present invention comprises a preparation step, a filling step, a first forming step, and a second forming step.

In the preparation step, a spherical center is formed which surrounds an accommodating space and forms a slit connecting the accommodating space on the surface. In the filling step, a wafer module and a battery electrically connected to the wafer module are inserted into the accommodating space via the slit of the center of the ball. In the first molding step, the center of the sphere is placed in a first molding die, and a sphere layer is formed outside the sphere. In the second molding step, the center of the core coated with the spherical layer is placed in a second molding die, and a spherical shell layer is formed outside the spherical layer to obtain a golf ball.

Another object of the present invention is to provide a golf ball produced by the manufacturing method.

Therefore, the golf ball of the present invention comprises a ball core surrounding an accommodating space, a wafer module disposed in the accommodating space of the ball center, and an electrical space disposed in the accommodating space of the ball center and electrically connected thereto. a battery of the wafer module, a sphere layer covering the core, and a spherical shell covering the sphere layer.

The effect of the invention is that, by inserting the wafer module and the battery into the formed and elastic core, the spherical core can be coated in a manner of hot-pressing the spherical layer and the spherical shell layer. The chip module and the battery function to insulate and protect the battery from variability and damage.

Referring to FIGS. 1 and 2, an embodiment of a method of manufacturing a golf ball 1 of the present invention includes a preparation step 21, a filling step 22, a first forming step 23, and a second forming step 24.

In this preparation step 21, a spherical core 3 having elasticity is prepared.

In this embodiment, the material of the core 3 is selected from the group consisting of epoxy resin (Epoxy) or rubber, and has been formed into a spherical shape.

Referring to FIG. 1 and FIG. 3, in the filling step 22, a wafer module 41 and a battery 42 electrically connected to the wafer module 41 are inserted into the accommodating space 31 via the slit 32 of the core 3, Since the core 3 has elasticity, the slit 32 can be sized to pass the wafer module 41 and the battery 42 and the semiconductor module 41 and the battery 42 are placed in the housing. After the space 31 is no longer applied to the core 3, the slit 32 is closed, and the wafer module 41 and the battery 42 are encapsulated in the core 3, and the accommodating space 31 is matched with the wafer module. 41 and the size of the battery 42 such that the center of gravity of the core 3, the die module 41, and the battery 42 coincide with the centroid of the core 3, that is, the wafer module 41 and the battery 42 are located therein. At the center of the center of the ball 3.

Referring to FIG. 1 and FIG. 4, in the first molding step 23, the core 3 in which the wafer module 41 and the battery 42 are packaged are placed in a first molding die 5, and the first molding die 5 includes a first molding die 5 a first upper mold body 51, a first lower mold body 52, and a plurality of first ejector pins 53 movably respectively disposed on the first upper mold body 51 and the first lower mold body 52, and a first thimble 53 disposed at the first upper mold body 51 The first guide groove 54 in the upper mold body 51. The first upper mold body 51 and the first lower mold body 52 define a first molding space 55 that communicates with the first flow guiding groove 54. Inserting the core 3 into the first molding space 55 and fixing the core 3 to the center of the first molding space 55 by the first ejector pins 53, so that the core 3 and the first upper mold body A gap is formed between the 51 and the first lower mold body 52, and then a plastic is heated to a semi-fluid shape, and then injected into the first flow guiding groove 54, so that the plastic is injected into the gap to form a spherical spherical layer 6 To cover the core 3 . In this embodiment, the spherical layer 6 has a lower melting point than the core 3, and the material thereof is selected from rubber or polymeric materials (Ionomer).

Referring to FIG. 1 , FIG. 5 , and FIG. 6 , in the second molding step 24 , the core 3 coated with the spherical layer 6 is placed in a second molding die 7 , and the second molding die 7 includes a first molding die 7 . a second upper mold body 71, a second lower mold body 72, a plurality of second ejector pins 73 that are movably respectively disposed to the second upper mold body 71 and the second lower mold body 72, and a second thimble 73 The second guide groove 74 in the upper mold body 71. The second upper mold body 71 and the second lower mold body 72 define a second molding space 75 that communicates with the second flow guiding groove 74. The spherical core 3 covered with the spherical layer 6 is placed in the second molding space 75, and the spherical layer 6 is fixed to the center of the second molding space 75 by the second ejector pins 73, so that the spherical layer 6 is A gap is formed between the second upper mold body 71 and the second lower mold body 72, and then a plastic is heated to a semi-fluid shape, and then injected into the second flow guiding groove 74 to form the plastic into the gap to form a gap. A spherical spherical shell layer 8 is coated to cover the sphere layer 6, and after being molded by cooling, a golf ball 1 as shown in Fig. 6 is obtained. In this embodiment, the material of the spherical shell layer 8 is selected from a polymer polymeric material (Ionomer) or a thermoplastic polyurethane (TPU).

Since the melting point of the core 3 is higher than that of the sphere layer 6, by encapsulating the wafer module 41 and the battery 42 in the core 3, heat insulation and protection can be generated to avoid the first molding. In step 23, the high temperature plastic directly contacts the battery 42 to cause variation and damage, and the wafer module 41 can also be protected from damage during the manufacturing process and affect the normal operation of the function. In addition, through the arrangement of the accommodating space 31, the wafer module 41 and the battery 42 are located at the center of the golf ball 1, so that the center of gravity of the golf ball 1 can coincide with the centroid without being offset, and the flight time is maintained. Stability.

In summary, the wafer module 41 and the battery 42 are covered by the core 3, which can be prevented from being directly damaged by the high temperature plastic during the manufacturing process, and can be insulated to prevent the battery 42 from being overheated. High and mutated, it is indeed possible to achieve the object of the present invention.
