Ultrasonic Welding Device and Ultrasonic Welding Method of Different Material Flooring

The present invention relates to an ultrasonic welding device and an ultrasonic welding method of a dissimilar material flooring material for manufacturing a flooring by bonding a plurality of welding objects formed of a dissimilar material.

In general, in the case of joining a flooring material composed of different materials, the adhesive is applied to any one of the upper member and the lower member, and then bonded. In this method, environmental pollution occurs according to the use of the adhesive, and the joint is not smooth. have.

To solve this problem, a technology for joining dissimilar material flooring materials using heat and pressure without using an adhesive has been developed. More specifically, after the upper member and the lower member is seated on a plate to which heat is applied, heat and pressure are applied to manufacture a dissimilar material flooring material.

However, this can be separated over time, the bonded part is separated, there was a problem that water or foreign matter flows into the separated part. In addition, heat is concentrated only on the upper and lower surfaces, so that the surface of the flooring material may not be smooth at the time of joining.

An object of the present invention is to provide an ultrasonic welding device and ultrasonic welding method of the heterogeneous material flooring material to be improved to be bonded without damaging the dissimilar material flooring material.

Ultrasonic welding device of the dissimilar material flooring material according to the present invention for achieving the above object is to produce a flooring by bonding a plurality of welding targets formed of a dissimilar material, and includes an anval and a horn. The anvil supports the welding objects and moves the welding objects in one direction. The horn presses the welding objects seated on the anvil and applies the ultrasonic vibrations to the welding objects to join the welding objects.

In addition, the ultrasonic welding method of the dissimilar material flooring material includes the steps of preparing the welding objects, the step of seating the welding objects on the anvil, and applying the ultrasonic vibration to the bonding objects. Preparing the welding objects provides a plurality of welding objects formed of different materials. The step of seating the deposit objects on the anvil seats the deposit objects on the rotationally driven anvil. The step of bonding the welding objects by applying ultrasonic vibration pressurizes the welding objects seated on the anvil, and joins the welding objects by applying ultrasonic vibration to the welding objects.

According to the present invention, as the welding objects are bonded using ultrasonic waves, the plurality of welding objects can be bonded without an adhesive. Accordingly, the bonded portion is not separated even after time can be used hygienically.

In addition, since the welding objects are disposed between the heated plates as in the related art, the surfaces of the welding objects may be smoothly formed at the time of bonding because the welding objects are bonded to each other by vibrating ultrasonic waves, that is, friction heat.

In addition, as the anvil and the horn are formed to rotate, the welding objects can be welded and transported without a separate transport means.

Figure 1 is a side view showing the configuration of the ultrasonic welding device of the different material flooring according to an embodiment of the present invention.

FIG. 2 is a side view of another embodiment of the horn of FIG. 1; FIG.

Figure 3 is a block diagram for explaining the process of the ultrasonic welding method of dissimilar material flooring according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the ultrasonic welding device and ultrasonic welding method of the different material flooring according to a preferred embodiment will be described in detail. Here, the same reference numerals are used for the same configurations, and detailed descriptions of well-known functions and configurations that may unnecessarily obscure the repeated description and the subject matter of the invention will be omitted. Embodiments of the invention are provided to more completely describe the present invention to those skilled in the art. Accordingly, the shape and size of elements in the drawings may be exaggerated for clarity.

As shown in FIG. 1, the ultrasonic welding device 100 of a heterogeneous material flooring material is for bonding a plurality of welding targets 10 formed of different materials to manufacture a flooring material. The anvil 110 and the horn 120 are connected to each other. Include.

The anvil 110 supports the welding targets 10 and transfers the welding targets 10 in one direction. More specifically, the anvil 110 may be formed of a roller formed to drive rotation. As the anvil 110 is formed to rotate in this manner, the welding objects 10 may be welded and transported without a separate transport means.

The horn 120 presses the welding targets 10 seated on the anvil 110 and applies the ultrasonic vibration to the welding targets 10 to bond the welding targets 10. More specifically, the horn 120 may be formed to be movable in the vertical direction and may apply ultrasonic vibrations of 16 kHz to 1 GHz to the welding target 10. This is because when the magnitude of the ultrasonic vibration is less than 16 kHz, the adhesion of the welding objects 10 may drop, and when the size of the ultrasonic vibration exceeds 1 GHz, the welding objects 10 may be deformed to the frictional heat.

Accordingly, the welding targets 10 are pressed between the anvil 110 and the horn 120, and at least one of the welding targets 10 is softened or melted by frictional heat to bond. At this time, the horn 120 is preferably applied a pressing force of 0.1kg / m ² ~ 20kg / m ² size to the welding target 10. This is because the magnitude of the pressing force can be modified to deposit the object 10 may be compromised if the adhesive force of the back 0.1kg / m ² under the deposition object (10), exceeding 20kg / m ^2.

The horn 120 may be formed of a roller formed to drive rotation similarly to the anvil 110. Accordingly, when the welding target 10 is disposed between the horn 120 and the anvil 110, the horn 120 pressurizes the welding target 10 and transfers the welding target 10 together with the anvil 110. Will be.

Meanwhile, as shown in FIG. 2, the horn 120 may be disposed to be spaced apart from the plurality of protrusions 121 on the pressing surface. As the plurality of protrusions 121 are spaced apart from each other on the pressing surface of the horn 120, an uneven pattern may be formed on one surface of the welding target 10 during ultrasonic bonding. Here, the size and shape of the protrusions 121 formed on the horn 120 may be variously modified according to the thickness and the material of the welding target 10, but is preferably formed in a hemispherical shape. This is to allow the protrusion 121 to easily escape from the welding target 10 during the rotation of the horn 120.

Figure 3 is a block diagram for explaining the process of the ultrasonic welding method of the different material flooring according to an embodiment of the present invention.

As shown in FIG. 3, the ultrasonic welding method 200 for dissimilar material flooring includes preparing the welding targets 210, mounting 220 the welding targets on the anvil 220, and applying an ultrasonic vibration to the welding targets. Bonding 230.

The preparing of the welding targets 210 may provide a plurality of welding targets 10 formed of different materials. Here, the welding target 10 is glass fiber, polyvinyl chloride (PVC: Polyvinyl Chloride), polyolefin (Polyolefin), polyethylene (PE: polyethylene), polyethylene terephthalate (PET: polyethylene terephthalate), polyethylene terephthalate glycol (PETG: Polyethylene terephthalate glycol (ACL), acrylonitrile butadiene styrene (ABS), polycarbonate (PC: Polycarbonate), styrene acrylonitrile copolymers (SAN), polymethylmethacrylate (PMMA) At least two of polyacrylate, polystyrene, and nylon may be selected.

For example, the glass fiber sheet, the PVC white sheet, and the PVC transparent film may be laminated in this order, and then ultrasonic welding may be performed. The glass fiber sheet, the PVC white sheet, Ultrasonic welding may be performed after the PE transparent films are laminated in sequence. In addition, the glass fiber sheet, the PE white sheet, and the PE transparent film may be laminated in order on the PVC base substrate, and then ultrasonic welding may be performed, or after the PE transparent film is laminated on the PE base substrate, ultrasonic welding may be performed. It may be. That is, the number and arrangement positions of the welding objects 10 are not limited, and may vary according to the needs of the implementer.

The step 220 of depositing the deposition targets on the anvil seats the deposition targets 10 on the anvil 110 that is rotationally driven. More specifically, the anvil 110 may be formed of a roller connected to the rotary actuator. As the anvil 110 is formed to rotate in this manner, the welding objects 10 may be welded and transported without a separate transport means.

On the other hand, the welding target object 10 is preferably transported at a speed of 1m / min ~ 400m / min, which is the welding target 10 is deformed by the frictional heat if the transport speed of the welding target 10 is less than 1m / min This is because, when the conveying speed of the welding target 10 exceeds 400m / min, the adhesion of the welding target 10 may fall.

The step 230 of bonding the welding objects by applying ultrasonic vibration pressurizes the welding targets 10 seated on the anvil 110 and applies the ultrasonic vibrations to the welding targets 10 to bond the welding targets 10. . At this time, the welding object 10 may be pressed and bonded through the horn 120 to rotate. As the horn 120 is formed to rotate in this manner, when the welding targets 10 are disposed between the horn 120 and the anvil 110, the horn 120 pressurizes the welding targets 10 and the anvil 110. The welding object 10 can be conveyed together.

The step 230 of bonding the welding objects by applying ultrasonic vibration may apply ultrasonic vibration of a size of 16 kHz to 1 GHz to the welding target 10. Accordingly, the welding objects 10 are pressed between the anvil 110 and the horn 120, and at least one of the welding objects 10 is softened or melted by frictional heat to bond. At this time, the welding object 10 may be applied a pressing force of 0.1kg / m ² ~ 20kg / m ² size. This is because the magnitude of the pressing force can be modified to deposit the object 10 may be compromised if the adhesive force of the back 0.1kg / m ² under the deposition object (10), exceeding 20kg / m ^2.

Meanwhile, the step 230 of bonding the welding objects by applying ultrasonic vibration may further include forming a concave-convex pattern on the welding objects 10. To this end, the horn 120 may be disposed a plurality of protrusions 121 on the pressing surface, respectively. Accordingly, when the horn 120 presses the welding targets 10, the uneven pattern is formed on the welding targets 10 by the pressing force. Here, the size and shape of the concavities and convexities formed on the welding objects 10 may be variously modified according to the thickness and the material of the welding objects 10, but are preferably formed in a hemispherical shape. This is to allow the protrusion 121 to easily escape from the welding target 10 during the rotation of the horn 120.

As described above, as the welding objects 10 are bonded using ultrasonic waves, the plurality of welding objects 10 may be bonded without an adhesive. Accordingly, the bonded portion is not separated even after time can be used hygienically.

In addition, since the welding targets 10 are disposed between the heated plates as in the related art, the welding targets 10 are joined by vibration of ultrasonic waves, that is, frictional heat, without being pressed and bonded to each other. It can be formed smoothly.

In addition, since the anvil 110 and the horn 120 are formed to rotate to rotate, the welding target objects 10 may be welded and transported without a separate transfer means.

Referring to Figure 3 describes the ultrasonic welding method 200 of the different material flooring as follows.

First, glass fiber, polyvinyl chloride (PVC), polyolefin (polyolefin), polyethylene (PE: polyethylene), polyethylene terephthalate (PET: polyethylene terephthalate), polyethylene terephthalate glycol (PETG: polyethylene terephthalate glycol), acrylic Acrylonitrile butadiene styrene (ABS), polycarbonate (PC: Polycarbonate), styrene acrylonitrile copolymers (SAN), polymethylmethacrylate (PMMA), polyacrylate (Polyacrylate) ), At least two or more welding objects 10 selected from polystyrene and nylon are prepared and laminated.

Then, the stacked welding objects 10 are seated on the anvil 110 for rotationally driving. Then, the horn 120 compresses the welding target object 10 with a pressing force of 0.1kg / m ² ~ 20kg / m ² size, and applies ultrasonic vibration of 16kHz ~ 1GHz size.

Accordingly, the welding objects 10 are pressed between the anvil 110 and the horn 120, and at least one of the welding objects 10 is softened or melted and joined by frictional heat. In this case, the plurality of protrusions 121 may be spaced apart from each other on the pressing surface of the horn 120 to form an uneven pattern on the welding target 10.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Could be. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.
