Description

How to print golf balls

The invention relates to a printing method, in particular to a golf ball printing method.

Generally, our impression of golf balls is that there are multiple holes of slightly different sizes on the ball, but in fact, golf balls are often printed with trademarks, patterns or decorative patterns on the surface. Allow players to easily observe the ball speed, rotation speed and landing point after hitting the ball. At present, the printing method commonly used by golf balls is to engrave a pattern on a printing plate. Print on the pattern, and finally imprint the rubber head with the transfer pattern made of ink on the surface of the golf ball, so that the transfer pattern is printed on the golf ball. However, there are often more than one place on the golf ball that needs to be printed, and the patterns are often different. In this way, it is necessary to prepare multiple printing plates with different patterns. Since the moving path of the rubber head is often relatively fixed, when printing different patterns For different positions of the golf ball (such as the top surface, the bottom surface and the middle ring surface), in addition to turning the golf ball to align the position to be printed upwards with the rubber head, it is also necessary to move the printing plate to align the rubber head , if there is a slight deviation in the displacement of the printing plate or the rotation of the golf ball, it will cause the printing pattern to shift. In addition, after the above-mentioned printing process is completed, it is necessary to manually check whether the printed pattern meets the standard, which is very labor-intensive and time-consuming, and the judgment accuracy is easily affected by human factors.

Therefore, the object of the present invention is to provide a printing method for the aforementioned printing device.

The golf ball printing method of the present invention comprises a ball entering step, a first printing step, an inspection step, a first drying step, a second printing step, a second drying step, and a ball picking step.

In the ball entering step, a sphere is moved into a first printing system, the sphere includes a top surface, a bottom surface opposite to the top surface, and an intermediate ring connecting the top surface and the bottom surface. In the first printing step, ink printing is performed on at least one of the top surface and the bottom surface with the first printing system. In the inspection step, the sphere is moved into an inspection machine, and the surface of the sphere is inspected by the inspection machine. In the first drying step, the sphere is moved into a first drying system for ink drying. In the second printing step, ink printing is carried out on the intermediate annular surface with a second printing system. In the second drying step, the sphere is moved into a second drying system for ink drying. In the ball taking step, the ball is removed from the second drying system.

The effect of the present invention is that by using the first and second printing systems to print on different positions of the sphere, the rotation of the sphere can be minimized, and the movement of the printing plate can be avoided, reducing the possibility of pattern deviation Moreover, the present invention also uses the inspection machine to automatically detect the pattern on the sphere, which can quickly monitor the printing quality of the sphere and avoid interference from human factors.

Another effect of the present invention is that before the printing process is completed, the inspection machine can be used to detect whether the pattern on the sphere has defects, which can avoid wasting ink and time costs, and does not need to stop the machine to observe whether the pattern is correct or not. have defects that result in reduced productivity.
