Description

Automatic applicator for blade bonding and coating table tennis racket {Automatic Applicator For Blade Bonding and Coating Table Tennis Racket}

The present invention relates to an automatic application device for adhering and coating table tennis racket blades.

Table tennis is a sport in which two (singles) or four (doubles) players compete by using table tennis rackets to hit a light, hollow ball over a table. Early table tennis rackets were made by stretching parchment paper over a rigid frame.

Recently, table tennis rackets are made of plywood and have rubber attached to one or both sides. The wooden part of a table tennis racket is called the blade and is usually made of several layers of wood, cork, fiberglass, carbon fiber, aluminum fiber or Kevlar material.

The material used for the blade must contain at least 85% wood, and there are no special restrictions on other materials used. Types of wood widely used as blade material include balsa, limba, walnut, cypress, and hinoki.

As mentioned above, the blade of a table tennis racket is usually made of multiple layers of wood, cork, fiber glass, carbon fiber, aluminum fiber, or Kevlar material, so each must be attached using adhesive.

In the past, in the process of making blades using adhesive, people worked manually, which slowed down the process and caused problems with inconsistent adhesive application, which increased the probability of defective products. Accordingly, research and development on how to apply adhesive uniformly and automatically is being actively conducted.

In addition, as mentioned above, rubber must be attached to the blade to make the table tennis racket that we use, so the blade and rubber must be well bonded to make a high-quality table tennis racket.

During the process of attaching the rubber to the blade, the wooden plate of the blade is damaged or the surface of the wood is damaged by the rubber. To prevent this, the blade is coated to form a thin coating film.

However, in the past, as people manually coated blades, the process was slow and the amount of coating applied was not constant, which arose. Specifically, if there is a part where the coating agent is not applied, the wood may be damaged in that part, and if a large amount of the coating agent is applied, the usability of the table tennis racket may be reduced when the rubber is attached. Accordingly, the need to develop technology that can uniformly and automatically apply the coating agent is increasing.

When the first material is applied through the application spray unit 23 and then washed with the second material, the first material and the second material may be collected together in the application collection unit 25. The material separation unit is disposed on the lower side of the application collection unit 25 to separate the first material and the second material from the mixture.

Specifically, the material separation unit may include a thermal separation unit and a rotational separation unit. The thermal separator can primarily separate the first material and the second material by applying heat, and the rotational separator can secondarily separate the first material and the second material through rotation.

In addition, the automatic coating device (S) for table tennis racket blade adhesion and coating according to an embodiment of the present invention may further include a chemical analysis unit (not shown). The chemical analysis unit is located separately from the material separation unit and analyzes the composition ratio of the second material separated by material separation to determine whether the first material has been completely separated, thereby preventing chemical components from being discharged to the outside.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the claims and equivalents of the claims as well as the claims described later.
