Description

Technical Field

[0001] The invention relates to a workpiece painting method, in particular to a workpiece painting method using magnetic adsorption for painting. Background Art

[0002] When consumers choose products, they pay more and more attention to the appearance of the products in addition to their functionality, especially the color of the products, which directly reflects the preferences of consumers. For example, golf clubs or golf club heads are usually made of metals such as alloys, and most of them show the metal color of the alloy itself, such as iron gray or silver. Therefore, in the subsequent processing, the golf clubs or golf club heads will be painted to make them have colors, but the color is still presented in a single color in appearance, which is slightly insufficient in terms of appearance changes. Summary of the invention

[0003] To solve the above problems, an object of the present invention is to provide a method for painting a workpiece, which can have better appearance variability.

[0004] The directions or their approximate terms described throughout the present invention, such as "front", "rear", "left", "right", "up (top)", "down (bottom)", "inside", "outside", "side", etc., mainly refer to the directions of the accompanying drawings, and each direction or its approximate terms are only used to assist in the explanation and understanding of the embodiments of the present invention, and are not used to limit the present invention.

[0005] The elements and components described throughout the present invention use the quantifiers "a" or "an" for convenience only and to provide a general meaning of the scope of the present invention; they should be interpreted in the present invention as including one or at least one, and a single concept also includes plural cases, unless it is obvious that it means otherwise.

[0006] The similar terms such as "combination", "assembly" or "assembly" described throughout the present invention mainly include the connection that can be separated without damaging the components, or the connection that makes the components inseparable, which can be selected by technicians in this field according to the materials of the components to be connected or the assembly requirements.

[0007] The workpiece painting method of the present invention comprises: applying magnetic paint on a painting part of a workpiece, the magnetic paint comprising particles of metal material; and placing the workpiece on a magnetic part and allowing it to stand for a predetermined time so that the magnetic force of the magnetic part is transmitted to the magnetic paint on the painting part.

[0008] Therefore, the workpiece painting method of the present invention applies magnetic paint to the painted portion of the workpiece and then places the magnetic part adjacent to the workpiece so that the magnetic paint can be displaced by the magnetic lines of force of the magnetic part. This can disturb the magnetic paint to form a variable color presentation, thereby achieving the effect of enriching the color variation.

[0009] The workpiece has a joint portion, which is located on a surface opposite to the painted portion, and the magnetic member is adjacent to the joint portion. There may be a distance between the painted portion and the joint portion, and the distance is 0.5 to 2.5 mm. In this way, the distance will not be too large, resulting in the magnetic force of the magnetic member being unable to be transmitted to the painted portion, and the effect of better magnetic conductivity is achieved.

[0010] The workpiece is a golf club, the paint-applied portion surrounds the outer tube wall of the workpiece, and the joint portion is located on the inner tube wall of the workpiece. In this way, the appearance of the golf club can achieve the effect of rich color variation.

[0011] The workpiece is a club head cover, and the paint application portion and the joint portion are respectively located on two opposite surfaces of the workpiece, so that the appearance of the club head cover can achieve the effect of rich color variation.

[0012] The thickness of the magnetic paint is 15-30 μm, so that the magnetic paint can be affected by the magnetic force of the magnetic element to produce color changes.

[0013] The magnetic conductive paint is applied to the painted portion of the workpiece by a drawing paint method, so that the effect of uniform painting can be achieved.

[0014] The metal particles include aluminum, silicon dioxide and nickel. Thus, the magnetic paint can be affected by the magnetic force of the magnetic element to produce a color change effect.

[0015] The particle size of the metal particles is 5-100 μm. Thus, different particle sizes can achieve better color variation.

[0016] The predetermined time is 1 to 10 minutes. In this way, the metal particles can be effectively displaced.

[0017] The workpiece is separated from the magnetic part after being left to stand, and the workpiece is baked at 80-120° C. for 5-15 minutes. In this way, the color of the magnetic paint can be fixed.

[0018] The magnetic part includes a plurality of components, the plurality of components are adjacent to the joint part, and at least one of the plurality of components is made of non-magnetic material. In this way, the local magnetic paint in the painted part will not be affected by the magnetic force and will not be displaced, which can further present a more diverse appearance.

[0020] Description of Reference Numerals 1: Workpiece 11: Painting Department 12: Joint 2: Magnetic parts 2a: Components. DETAILED DESCRIPTION

[0021] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are listed below and described in detail with reference to the accompanying drawings; in addition, those marked with the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0022] Please refer to Figure 1 As shown, it is a first embodiment of the workpiece painting method of the present invention, comprising painting a surface of a workpiece 1, and placing the workpiece 1 on a magnetic member 2 for a predetermined time.

[0023] The workpiece 1 can be any product that needs to be colored. For example, the workpiece 1 can be a golf club head cover or a golf club. The workpiece 1 has a paint portion 11, which can be located on a surface of the workpiece 1. The workpiece 1 has a joint portion 12, which is located on a surface opposite to the paint portion 11. The joint portion 12 can be adjacent to the magnetic member 2 so that the magnetic force of the magnetic member 2 can be transmitted to the paint portion 11. There can be a spacing between the paint portion 11 and the joint portion 12, and the spacing is 0.5 to 2.5 mm. In this way, the magnetic force of the magnetic member 2 can be transmitted to the paint portion 11, and will not be unable to be transmitted to the paint portion 11 due to the excessive spacing. In this embodiment, the workpiece 1 is a hollow tube body for forming a golf club, the paint portion 11 surrounds the outer tube wall of the workpiece 1, and the joint portion 12 is located on the inner tube wall of the workpiece 1. In another embodiment, the workpiece 1 may be a club head cover, and the paint-applied portion 11 and the connecting portion 12 are respectively located on two opposite surfaces of the workpiece 1 .

[0024] Then, a magnetic paint having a thickness of 15 to 30 μm is applied to the painted portion 11 of the workpiece 1. The magnetic paint has a predetermined color so that the workpiece 1 can present a color on the surface. The magnetic paint can be applied to the painted portion 11 of the workpiece 1 by a drawing paint method. That is, the painted portion 11 of the workpiece 1 is axially inserted into a paint tank through a transport mechanism such as a track, and the magnetic paint can be attached to the painted portion 11 of the workpiece 1 after the painted portion 11 of the workpiece 1 axially passes through the paint tank. It is worth noting that the magnetic paint on the workpiece 1 includes particles having a metal material. For example, the magnetic paint can be a magnetic pearlescent paint. Specifically, the magnetic pearlescent paint is based on mica or fish scales as base particles, and the base particles are coated with at least one layer of metal oxides such as iron oxide to form the metal particles. In this embodiment, the specific components of the particles with metal material include aluminum (Al), silicon dioxide (SiO2) and nickel (Ni), and the particle size of the particles with metal material can be 5-100 μm. In another embodiment, the particle size of the particles with metal material is 5-25 μm, so that a relatively small particle size can present a more delicate and soft color. In other embodiments, the particle size of the particles with metal material can be 60-100 μm, so that a relatively large particle size can present a three-dimensional color.

[0025] Preferably, before applying the magnetic paint to the painted portion 11 of the workpiece 1, the painted portion 11 may be pre-coated with a base coating, which may be used to fill holes, depressions and other defects of the painted portion 11, thereby preventing the defects from causing uneven light reflection and affecting the color and gloss. In addition, the base coating may cover the color of the painted portion 11 itself, thereby preventing the color of the painted portion 11 itself from affecting the color of the magnetic paint. In this embodiment, the base coating may be gray, white or black, so that the base coating may further set off the color of the magnetic paint.

[0026] Please refer to Figure 1 , Figure 3As shown, the magnetic member 2 is placed adjacent to the joint 12 of the workpiece 1 for a predetermined time, which can be 1 to 10 minutes, so that the magnetic force of the magnetic member 2 can be transmitted to the painted portion 11. Preferably, the magnetic member 2 can be attached to the joint 12 so that the magnetic member 2 has a better magnetic force transmission effect. The magnetic member 2 can be made of a material such as an existing magnet such as a neodymium iron boron alloy, so that the magnetic member 2 can generate magnetic force, and the magnetic induction intensity of the magnetic member 2 can be 1500 to 4000 Gauss (Gs). In this embodiment, the magnetic member 2 is a rod body, and the outer diameter of the magnetic member 2 is slightly smaller than the inner diameter of the workpiece 1 so that the magnetic member 2 can be adjacent to the inner tube wall of the golf club of the workpiece 1. At this time, the metal particles in the magnetic paint located in the paint portion 11 are affected by the magnetic force of the magnetic member 2 and begin to be displaced by the magnetic force lines of the magnetic member 2, thereby disturbing the magnetic paint to form a variable color presentation. The workpiece 1 is then separated from the magnetic member 2 after being left to stand, and the workpiece 1 is baked at 80-120° C. for 5-15 minutes to fix the magnetic paint.

[0027] Preferably, a protective paint can be coated on the magnetic paint. The protective paint can be formed by coating with PU paint. Through the wear resistance of the protective paint and the properties of better material life, the magnetic paint can be well protected. The protective paint is transparent PU paint to avoid obstruction of the magnetic paint.

[0028] Please refer to Figure 2 As shown, it is the second embodiment of the workpiece painting method of the present invention. This embodiment is roughly the same as the first embodiment mentioned above. In this embodiment, the magnetic member 2 is formed by combining multiple components 2a. The multiple components 2a can be combined by snapping, locking, bonding or screwing. In the second embodiment, taking the multiple components 2a as multiple short rods as an example, two adjacent components 2a can be connected by screwing. In this way, the multiple components 2a can be used to insert the inner tube wall of the golf club of the workpiece 1 after being connected. It is worth noting that at least one component 2a of the multiple components 2a is formed of non-magnetic material, that is, at least one component 2a does not have magnetic force. When the non-magnetic part of the magnetic member 2 is adjacent to the joint 12, the local magnetic paint in the painting part 11 will not be affected by the magnetic force and will not be displaced, which can further present more diverse appearance variability.

[0029] In summary, the workpiece painting method of the present invention applies magnetic paint to the painted portion of the workpiece and then places the magnetic part adjacent to the workpiece so that the magnetic paint can be displaced by the magnetic lines of force of the magnetic part. This can disturb the magnetic paint to form a variable color presentation, thereby achieving the effect of enriching the color variability.

[0030] Although the present invention has been disclosed using the above preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the technical scope protected by the present invention is still within the scope of the present invention. Therefore, the protection scope of the present invention includes all changes within the meaning and equivalent scope of the claims. In addition, when the above several embodiments can be combined, the present invention includes any combination of implementations.
