The present invention is a terminal welding device for high voltage capacitors, which allows welding of the cap and ground plate in which the center conductor and the knife terminal are coupled to the dielectric to exactly match their position and spacing, etc. It is about.

As the development of the industry, many tools that are convenient for human life are being developed. One of them, the microwave oven, which can cook food in a short time, adds convenience to our kitchen life.

In the microwave oven, a high voltage capacitor that needs to accumulate and emit a large amount of current and voltage is necessary. These high voltage capacitors have realized the dream as dielectrics obtained by firing ceramics, which are called dream materials of the 21st century.

Such high voltage capacitor is corona discharge occurs if the welding position or spacing of the knife terminal, the center conductor, and the ground plate, etc., which are integrally welded to the dielectric as long as the high voltage is loaded on the dielectric does not exactly match, the dielectric breakdown voltage As a result of the phenomenon, it was not possible to function properly, and the most important task was that these knife terminals, the center conductor, and the ground plate were correctly welded to the dielectric.

However, until now, when printing knife terminals, center conductors, ground plates, etc. on dielectrics, the distance between welded knife terminals does not match by simple manual work or welding of knife terminals, center conductors, ground plates, etc. in a free state. Of course, the core conductor is inclined or tilted to one side, so that it is not possible to perform the function as a high voltage capacitor due to the failure of accurate welding.

The present invention has been devised to solve the above problems so that at least one or more guide pins are protruded and seating blocks are formed on both sides thereof, the guide pins of the bed are coupled to the seating blocks, and a plurality of A ground plate storage die having a heat generating hole and a ground plate storage groove, a dielectric positioning die having a dielectric storing hole coupled to the ground plate storage die, and a guide post formed in the bed to move up and down to sandwich the dielectric and knife terminals. At the same time, it is composed of a fusion die for heating the dielectric and the terminal set by heating the internally mounted heater rod to fuse the terminal set and the ground plate to the dielectric.

Here, the fusion die is mounted on both sides of the die main body with a heater rod mounted therein and a reference block formed at the bottom center thereof, and a knife terminal pinching block which is in close contact with both sides of the reference block and clamps the knife terminal inside the spring. At the bottom, the dielectric pinching block, which forms a plurality of dielectric pinching grooves facing each other, is configured to be loosened by the operation of a single cylinder.

Here, the fusion die is configured such that the dielectric sandwiching block sandwiches the dielectric while the knife terminal sandwiching block first clamps the terminal set.

Referring to the present invention described above in detail based on Figure 1 as follows.

At least one guide pin 11 is formed on the central upper surface of the bed 10 made of a flat plate, and seating blocks 12 are formed on both sides of the guide pin 11.

In addition, at least two guide posts 15 may be installed at both sides of the seating block 12, and the fusion die 20 may be configured to be lifted from the upper side of the bed 10 guided to the guide post 15.

Here, the fusion die 20 has a heater body 21 mounted therein and a die body 22 having a reference block 22a formed at the center of the bottom thereof, and the cylinder body 23 which is installed on both sides of the die body 22. A gripping block 24 having a dielectric clamping groove 24a formed at the lower end of the loosening operation, and a spring block 25 installed inside the gripping block 24 are mounted on the reference block 22a of the die body 22. It consists of the knife terminal clamping block 26 which closely adheres and clamps the knife terminal 31 of the terminal set 50. As shown in FIG.

In addition, the ground plate storage die 30 coupled to the guide 11 of the bed 10 and seated on the seating block 12 includes a plurality of heat generating holes 31 and ground plate storage for dissipating heat generated during welding. The groove 35 and the guide protrusion 33 were formed.

In addition, a dielectric positioning die coupled to the upper guide protrusion 33 of the ground plate storage die 30 to form a dielectric housing hole 45 for guiding the dielectric 55 accurately on the ground plate 56. 40).

Referring to the operation and effect of the present invention having the above configuration is as follows.

First, the fusion die 20 installed to move up and down on the bed 10 is raised to the maximum, and then the ground plate storage die 30 is seated on the seating block 12 of the bed 10.

At this time, the ground plate storage die 30 is coupled to the guide pin 11 of the bed 10 and its position is always consistent.

In the above state, the ground plates 56 are respectively inserted into the ground plate storing grooves 32 of the ground plate storing die 30 seated on the inner block of the bed 10, and the dielectric positioning die 40 is inserted into the ground plate. It is coupled to the guide protrusion 33 of the storage die (30).

In this way, the center conductor 51 integrally coupled to the terminal set 50 is firstly fused to the inside of the dielectric housing hole 45 of the dielectric positioning die 40 coupled to the ground plate storage die 30. Insert the dielectric 55 therein.

As described above, when the inserting operation of the dielectric 55 to which the terminal set 50 is coupled is completed, the fusion die 20 is lowered.

In this case, the fusion die 20 can be lowered in various ways such as a cylinder or a lead screw, and if necessary, the bed 10 may be raised and lowered.

When the fusion die 20 is lowered in the above-described operation, the knife terminal 52 of the terminal set 50 is sandwiched between the reference block 22a and the knife terminal sandwiching block 26 and the dielectric 55 is interposed between the sandwiching blocks 24. It is located in the dielectric clamping groove (24a) of.

When the clamping block 24 is clamped in the above state, the knife terminal clamping block 26, which is installed so as to be held on the spring 25 inside the clamping block 24, is in close contact with the reference block 22a while the knife terminal 52 is closed. After pinching the pin to fix the position of the terminal set 50, the dielectric pinching groove 24a of the pinching block 24 pinches the dielectric 55 to fix the dielectric position.

In the above state, the heat of the heater rod 20 mounted inside the fusion die 20 heats the dielectric 55 and the terminal set 50 so that the terminal set 50 and the ground plate 56 are separated from the dielectric 55. To the correct position.

In the present invention, when the dielectric, the ground plate, and the terminal set are fusion bonded, they are fused to each other at the correct position, thereby eliminating the possibility of causing corona discharge. It is a new and useful design that can help breakthroughs in the manufacture of high voltage capacitors, such as no cost or impairment of efficiency, and easy operation to improve production efficiency.
