Abstract
The present invention proposes an ultrasonic welding apparatus of an electric mat capable of mass production with uniform quality. The ultrasonic fusing apparatus of the present invention includes a mold 42 having a plurality of fusing pins 44 provided to the ultrasonic horn 48 so as to fuse the upper and lower fabrics with the ultrasonic horn 48, ; An upper frame 12 installed on the upper side of the mold to support the mold; A lower end portion connected to the metal mold, and an upper end portion of the support shaft being installed through the upper frame; A height adjusting nut (54) screwed to the support shaft (52) at an upper portion of the upper frame to adjust the height of the mold; A spring 56 inserted into a support shaft under the upper frame 12; And an elasticity adjusting nut 58 installed between the lower end of the spring 56 and the metal mold and capable of adjusting the elastic force of the spring through adjustment of the height by rotation. It is possible to mass-produce a high-quality electric mat in accordance with the leveling of the fusing pin and the uniform contact pressure with the ultrasonic horn.
Description
The present invention relates to an ultrasonic welding apparatus for manufacturing an electric mat, and more particularly, to an ultrasonic welding apparatus capable of accurately maintaining smoothness between a fusing pin and an ultrasonic horn of a fusing apparatus for forming a large number of fusing points on a large surface of an electric mat And an ultrasonic fusing device for manufacturing an electric mat, which is configured to manufacture a high quality electric mat.
An electric mat, also commonly referred to as an electric yam, can be said to be a heating product that utilizes the heat generated from the heat rays disposed therein. A general method of manufacturing such an electric mat is to first make a mat using sewing, and then insert a hot wire between the sewing lines. However, this method relies on the manual operation of the operator because it is practically very difficult to automate the process of inserting the hot wire substantially along the lines of the sewing lines.
In this way, the work of inserting the hot wire along the sewing lines by the manual operation of the operator poses a problem that productivity is inevitably pointed out to the workability, and the work environment of the worker due to the size of the electric mat is inferior. In addition to the problem of working environment and productivity, the problem of safety is also pointed out that the hot wire inserted into the inside of the sewing line can not maintain the original position.
In order to solve such disadvantages, the present inventor has developed an electric mat which is configured to be able to join the upper and lower fabrics to each other by using ultrasonic welding. Before the upper and lower fabrics are partially integrated with each other by ultrasonic welding, a hot wire should be arranged between the upper and lower fabrics so as to maintain a fixed state.
If the upper and lower fabrics are fixed to each other by forming a plurality of welding points in a state where the hot wire is fixed, it is of course possible to maintain the predetermined arrangement between the upper and lower fabrics . If such ultrasonic welding is used, sewing becomes unnecessary, and productivity of the electric mat can be substantially improved.
As such, electric mats have a considerable area even if they are actually single occupants. It is practically unreasonable that a plurality of welding points are generated in the entire mat by an ultrasonic welding process in such an electric mat having such a large area. That is, a plurality of ultrasonic horns and a plurality of mold assemblies can be used for ultrasonic welding the upper and lower fabrics of the electric mat.
In the case of using a plurality of ultrasonic horns and mold assemblies, it is desirable to be able to provide a substantially uniform contact pressure, but it is practically difficult to provide a uniform contact pressure for numerous ultrasonic welding points. For example, the upper surface (horizontal surface) of the ultrasonic horn at the bottom and the plurality of fused fins formed at the lower portion of the mold assembly have the same flatness, so that the ultrasonic welding can be uniformly performed as a whole.
An object of the present invention is to provide an electric mattress capable of uniform contact between an ultrasonic horn and a plurality of fusing pins for forming a plurality of ultrasonic welding points in order to manufacture an electric mat by combining an upper fabric and a lower fabric by ultrasonic welding, And it is an object of the present invention to provide a fusing device.
The object of the present invention is to substantially equalize the uniform quality of the ultrasonic welding quality through the uniform contact maintenance, and thus to improve the quality of the electric mat as a whole It is also to do.
According to the present invention, there is provided an ultrasonic fusing apparatus for an electric mat for fixing a plurality of fusing points on an upper and lower ends of an electric mat and fixing a heat line disposed therebetween; A mold having a plurality of fused fins provided on an ultrasonic horn for fusing an upper fabric and a lower fabric between the horn and the horn; An upper frame installed on the upper side of the mold to support the mold; A lower end connected to the mold, and an upper end connected to the upper frame through a support shaft; A height adjusting nut screwed to the support shaft at an upper portion of the upper frame to adjust the height of the mold; A spring inserted into a support shaft under the
In the ultrasonic welding apparatus of the present invention, it is preferable that a plurality of molds and ultrasonic horns are arranged in a row along the longitudinal direction of the electric mat.
Further, it is preferable that a heater for heating is provided in the mold in view of the quality of ultrasonic welding.
According to the present invention as described above, the upper and lower fabrics can be kept fixed to each other by ultrasonic welding with the hot wire disposed in a certain shape interposed therebetween. And the internal heat ray can maintain the shape (for example, a zigzag arrangement) arranged by a plurality of ultrasonic welding points. When the apparatus of the present invention is used as described above, ultrasonic welding is most basically used, and thus it can be most advantageous in terms of productivity improvement.
According to the present invention, not only the flatness (horizontality) between the fusing pin and the ultrasonic horn can be accurately controlled, but also the contact pressure can be maintained uniformly. Accordingly, it is expected that a plurality of welding points formed between the upper and lower fabrics can be uniformly molded with reliable quality. This is expected to be an advantage of ensuring high quality, as well as ensuring the safety of the electric mat.
