The painting method for the golf club head comprises the following steps: providing a template, wherein the template is a painting path corresponding to a painting part on a golf club head semi-finished product; picking up a painting part of the golf club head semi-finished product in the painting operation, and comparing the actual position of the painting part in the painting operation with the position of the painting part in the sample plate to obtain an offset value; positioning the painting path after the actual position of the painting part in the painting operation is positioned in the position of the painting part in the sample plate according to the deviation value; and injecting paint into the painting part by a painting device according to the painting path.

Therefore, the painting method of the golf club head of the invention can obtain the painting path from the painting part after picking up the painting part of the golf club head semi-finished product so as to inject paint into the golf club head semi-finished product, thereby reducing the labor cost and realizing the effect of improving the processing efficiency. In addition, an included angle smaller than 20 degrees is formed between the tangent plane of any point on the painting part and the horizontal tangent plane, so that paint overflow caused by excessive inclination of the painting part can be avoided, and the effect of improving the painting quality is realized.

Wherein, the lacquering part is a containing groove formed by the surrounding of a groove, a character, a pattern, a line groove or a convex rib. Therefore, the pick-up device can identify the undulation structure on the surface of the golf club head semi-finished product.

Wherein the width between the opposite sides of the painting part is more than or equal to 0.1mm, and the depth of the painting part is 0.1-3 mm. Thus, the effect of preventing paint overflow caused by over-narrow accommodating groove is achieved.

Wherein, the painting device uses a piezoelectric injection valve or a pneumatic injection valve to paint. Therefore, the paint discharging amount can be controlled more accurately, and the effect of avoiding uneven painting or paint overflow is achieved.

Wherein, the paint outlet of the painting device injects paint into the painting part at a distance less than 5 mm. Therefore, the effect that the paint yield is reduced due to paint splashing and overflowing caused by the fact that the distance between the paint outlet and the painting part is too far can be avoided.

Wherein, the painting device injects paint at a speed of 1-300 mm/s according to the painting path. Therefore, the paint filling device has the effect of ensuring that the paint filling device can stably and quickly fill the paint in the paint filling part.

Wherein, the painting device injects paint at a speed of 3-60 mm/s according to the painting path. Thus, the painting device has the effect of ensuring that the painting device can stably inject the paint into the painting part.

The painting method of the golf club head further comprises the step of standing the golf club head semi-finished product injected with the paint for 3-10 min and then baking the golf club head semi-finished product at 80-120 ℃ for 15-45 min. Therefore, the paint can be solidified and shaped, and the paint has the effect of preventing the paint from falling off from the painting part.

Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:

as shown in fig. 1, the method for painting a golf club head according to the present invention comprises: the method comprises the steps of picking up a painting part 11 on a golf club head semi-finished product 1, obtaining a painting path according to the painting part 11, and injecting paint into the painting part according to the painting path.

The painting portion 11 is provided on one surface of the golf club head semi-finished product 1, for example, the painting portion 11 may be a groove, the groove may form characters, patterns or symbols on the surface of the golf club head semi-finished product, or the painting portion 11 may be a groove, a groove surrounded by a protruding rib, or the like, but the invention is not limited thereto, and thus paint may be poured into the painting portion 11 to present predetermined numbers, patterns or symbols. In this embodiment, the width between the opposite sides of the containing groove of the painting part 11 can be greater than or equal to 0.1mm, and the depth of the containing groove can be 0.1-3 mm, so that paint overflow caused by too narrow containing groove can be avoided.

The painting portion 11 of the golf club head semi-finished product 1 is captured to obtain the image of the painting portion 11, for example, the image can be captured by a capturing device, such as a CCD image lens, to capture the image of the painting portion 11, or the capturing device can be a scanning lens, so that the contour of the painting portion 11 can be scanned, and the grooves, grooves or protruding ribs on the painting portion 11 can be captured. And the result of the painting part 11 of the golf club head semi-finished product 1 is recorded in an arithmetic unit, which can be a computer, or other devices with arithmetic processing function, and the invention is not limited thereto.
