Description
The present invention relates to an induction heating apparatus, a shoe making apparatus and a shoe making method using the induction heating apparatus, and more particularly, to an induction heating apparatus, a three-dimensional object bonding method, A footwear manufacturing apparatus using the same, and a footwear manufacturing method.
Generally, the shoe is largely composed of an upper and a sole, and the sole is made up of an outsole, a midsole, and an insole. Each part is made through each manufacturing process and then assembled with an adhesive. Therefore, the shoe manufacturing process can be divided into the parts manufacturing process and the assembling process of assembling these parts.
In addition, shoe materials are typical nonpolar materials and adhesion is very difficult, so various pretreatment processes are required. The pretreatment process is a pretreatment process before applying an adhesive to bond shoe parts composed of an outsole, a midsole and an upper part. The cleaning is a process of removing contaminants such as a mold release agent on the surface of each component . For example, the ultraviolet treatment process changes the surface of a material by a chemical method, and the primer is an indispensable process for enhancing adhesion force to be used for enhancing the bonding force with an adhesive.
Conventional wet adhesive heating method uses hot air, which causes damage to the material at high temperature by applying energy to the front side of the material after the adhesive is applied. That is, a conventional wet adhesive needs to be dried after application, and a material sensitive to the drying temperature may cause a change in physical properties. In particular, in the case of midsole, problems such as dimensional stability arise when the drying temperature is higher than 60 ° C.
Also, existing wet adhesives require a post-application drying process, and existing shoe bonding processes are produced through a preparation process and a finished adhesive process, which complicates the production process.
In addition, when the adhesive surface of the shoe material parts has a curvature, the heat transmitted to the adhesive agent is not uniform, so that the adhesive strength varies over the entire adhesive surface, thereby deteriorating the reliability of the product.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an induction heating apparatus for three-dimensional object bonding capable of efficiently bonding three-dimensional objects having curved surfaces.
Another object of the present invention is to provide a shoe manufacturing apparatus and a shoe manufacturing method capable of improving the reliability of a product by making the adhesive strength of the adhesive layer provided in the shoe soles uniform.
According to an aspect of the present invention, there is provided an electronic device comprising: an induction coil unit for forming a magnetic field in an induction heating space for heating metal particles of an adhesive layer disposed between a curved surface of a first object to be bonded and a second object to be bonded; An inverter unit for supplying an alternating current to the induction coil unit; The induction coil unit may include an induction coil unit such that the temperature of the adhesive layer due to the heating of the metal particles is within an allowable temperature range over the entire adhesive layer, And a second induction coil part disposed at a predetermined distance apart in the lower direction of the second object to be bonded, the first induction coil part being disposed at a predetermined distance in the upper direction of the first object to be bonded, An object induction heating apparatus is provided.
Wherein the first induction coil portion includes a first base member having a flat plate shape and a first induction coil provided on the first base member, wherein an installation area of the first induction coil is a projected area .
In order to form a magnetic field of uniform intensity on the induction heating space, the first induction coil part and the second induction coil part may have the same shape and size and be arranged symmetrically with respect to the adhesive layer.
According to another embodiment of the present invention, the present invention provides the above-mentioned three-dimensional object bonding induction heating apparatus; A transfer unit for transferring the first object to be bonded and the second object to be laminated via the adhesive layer to the induction heating space; And a pressing unit for pressing the first bonding object bonded by the adhesive layer and the second bonding object.
The transfer unit includes a moving member moving through the induction heating space, and the moving member can be made of a non-metallic material that is not affected by a magnetic field.
The transfer unit may further include an object fixing member for preventing the alignment of the bonding objects from being disturbed when the first bonding object and the second bonding object are transferred in a stacked state.
According to still another aspect of the present invention, there is provided a method of manufacturing a semiconductor device, comprising: an adhesive layer forming step of forming an adhesive layer containing metal particles between a curved surface of a first object to be bonded and a second object to be bonded; A current applying step of applying an alternating current to a first induction coil part disposed at a predetermined distance apart in an upper direction of the first object to be bonded and a second induction coil part arranged at a predetermined distance apart in a downward direction of the second object to be bonded; A transfer step of transferring the first object to be bonded and the second object to be bonded through the adhesive layer to an induction heating space in which a magnetic field is formed by the first induction coil part and the second induction coil part; And a pressing step of pressing the first adhesive object and the second adhesive object adhered by the adhesive layer.
The adhesive layer is provided as an adhesive layer in the form of a film, and the adhesive layer forming step may arrange the adhesive layer in a film form between the first object to be adhered and the second object to be adhered.
