Description

Automatic Resin Filling and Curing Device for Box Capacitor Assembly Equipment

The present invention relates to a box-type capacitor assembly device, and more particularly to an automatic resin filling and curing device applied to such a box-type capacitor assembly device.

Capacitors are widely used in the electrical and electronic fields, and the present invention relates to the manufacture of such capacitors. In particular, the present invention relates to the production of so-called "box capacitors". In practice, the manufacture of a box-type capacitor involves two processes: manufacturing a capacitor core or element, and a casing in which the capacitor core is sealed with resin, for example, after the capacitor core is charged, and soldering a conductive terminal line to the capacitor core. After depositing the capacitor core in the casing, the casing may be divided into a process of sealing the casing with a resin so as to fix the capacitor core in the casing. The resin is cured, for example, by an elevated temperature, thereby forming a final capacitor product.

In general, the process of filling the resin into the capacitor casing is divided into two steps. That is, the resin is first filled in the casing to occupy approximately 70 to 80% of the casing volume, which is referred to as "primary resin bedding operation". Thereafter, the capacitor core is partially immersed in the resin with the capacitor core charged in the casing. In this state, the resin is cured by a curing oven that provides a high temperature to cure it, which is the "primary curing operation". Then, the resin is completely filled again in the casing, which is a "secondary filling operation". After this secondary filling operation, a "secondary curing operation" is performed, whereby the resin is completely cured, thereby forming a final capacitor product.

In some conventional box-type capacitor assembly apparatus, the filling and curing operations are performed completely manually or partially manually. Therefore, the defective rate of the product tends to increase. Moreover, in the curing operation, it is necessary to keep the box-type capacitor at a high temperature for a predetermined period so that the resin can be completely cured. In order to heat the capacitors for a sufficient period, a large curing oven that occupies a large floor area must be used. .

Therefore, it is desirable to provide an automatic resin filling and curing apparatus capable of reducing the floor area required for installation of a curing oven, as well as operating completely automatically in order to solve the problems encountered in the prior art.

Therefore, an object of the present invention is to achieve a completely automatic filling of resin into the casing of the box capacitor and curing of the filled resin, thereby reducing the defective rate of the product, thereby lowering the manufacturing cost of the box capacitor. It is to provide an automatic resin filling and curing device of the assembly device.

Another object of the present invention is to provide an automatic resin filling and curing apparatus of a box-type capacitor assembly device having a curing oven having a two-layer configuration to reduce the floor area occupied.

These objects are to accommodate the primary resin-filled capacitor semi-finished products from the box-type capacitor assembly device and to sequentially transfer the capacitor semi-finished products into the lower layer of the first tunnel of the curing oven having a lower layer and an upper layer thereon according to the present invention. An automatic resin filling and curing apparatus including a capacitor supply system is provided. The first tunnel includes a first elevator for transferring the capacitor semi-finished products passing through the lower layer of the first tunnel to the upper layer and passing through the upper layer. Subsequently, the capacitor semifinished products are refilled with resin and, in this state, are transferred to the second tunnel of the hardening oven having a lower layer and an upper layer thereon, so that the capacitor semifinished products are moved into the upper layer of the second tunnel. The second tunnel includes a second elevator for transferring the capacitor semifinished products from the upper layer to the lower layer. The total length of the top and bottom layers of each of the first and second tunnels is of sufficient length to fully cure the resin. In addition, a collecting device is provided to collect the final capacitor product that passes through the lower layer of the second tunnel in the state where the resin is completely cured.

In order to be able to fully understand the embodiment of the present invention, first, a brief description will be given of a capacitor assembling apparatus to which the production of the electric capacitor related to the present invention and the automatic resin filling and curing device of the present invention are applied. The electric capacitor to be manufactured in the present invention is called a "box type capacitor", and in the manufacture of such a box type capacitor, a capacitor element or a core and an insulating casing are first manufactured separately. The capacitor assembly device is used to place the capacitor element thus manufactured in an insulating casing and to fill an appropriate amount of resin in the casing. Once the resin has cured, the manufacture of the box capacitor is complete. Generally, two resin filling operations are performed in practice, and a curing operation is performed to cure the filled resin after each resin filling operation. The present invention relates to an apparatus for performing secondary resin filling and curing operation to automatically cure a box-type capacitor semifinished product in a state where a primary filling operation has been performed, and then complete the manufacture of the box-type capacitor.

In the accompanying drawings, in particular FIG. 1, there is shown an automatic resin filling and curing apparatus applied to a box type capacitor assembling apparatus constructed in accordance with a suitable embodiment of the present invention. A capacitor supply device 12 for supplying a capacitor semifinished product of the present invention. The capacitor semifinished product represents an intermediate product of a box-type capacitor in which primary resin filling is performed but no curing operation is performed (in other words, the capacitor semifinished product contains an uncured resin filled therein during the primary resin filling operation. do). The capacitor supply device 12 moves the supplied capacitor semifinished product along the first path toward the curing oven 14 to enter the first end of the curing oven 14, and then the curing oven 14. Allow the inside to pass through to cure the resin filled by the primary filling operation. This is the "primary curing operation". The automatic resin filling and curing device 10 also includes a conveying device 16 for transferring the primary cured capacitor semifinished product to the secondary resin filling device 18 for performing a secondary resin filling operation. The secondary filled capacitor semifinished product passes through the curing oven 14 through the first end of the curing oven 14 along the second path by the transfer device 16 and is thus secondary cured. That is, the secondary filled capacitor semifinished product is to be cured its secondary filled resin by the high temperature inside the curing oven (14). The capacitor semifinished product processed by the secondary curing operation is a final capacitor, which is transferred from the automatic filling and curing device 10 by the collecting device 22 to collect the tank 24 (Figs. 28 and 29). (Shown in dashed lines).

According to the present invention, the first and second paths preferably extend through the curing oven 14 in a substantially parallel state, guiding the semi-conductor semifinished product through the curing oven 14 to a high temperature in the curing oven 14. By this, the resin of the capacitor semifinished product can be cured. The first and second paths each include a guide means, such as a guide rail, which guides the capacitor semifinished product along its first and second paths. According to the present invention, the curing oven 14 is composed of a single oven device having a tunnel extending in the first direction from the first end to the second end on the opposite side. The tunnel may consist of a single tunnel in which both the first and second paths extend, or may be divided into two sub-tunnels in which the first and second paths extend respectively. According to another embodiment of the present invention, the curing oven 14 may be composed of two independent ovens each having a tunnel in which the first and second paths extend. Although the detailed description of the structure of the curing oven 14 is omitted for simplicity, it should be noted that the curing oven 14 has enough space for the first and second paths to pass through. The space may consist of a single tunnel in which the first and second paths extend in common, and the tunnel may be divided into two sub-tunnels in which the first and second paths may respectively extend. The space may also consist of two independent tunnels in which the first and second paths extend respectively. For simplicity, the curing oven 14 will have two tunnels respectively corresponding to the first and second paths, but the actual structure of the curing oven 14 is not limited thereto.

2 is a perspective view of the capacitor supply device 12 of the automatic filling and curing device 10 of the present invention, Figures 3 to 6 shows the operation of the capacitor semi-finished product supply of the capacitor supply device 12 These are the floor plans. The capacitor supply 12 includes a turntable 26 composed of a disc-shaped member that is rotatable in the direction indicated by arrow A about the central axis so as to be periodically movable between the capacitor receiving position and the capacitor conveying position. On the circumference of the turntable 26 a plurality of capacitor receiving portions 28 are formed at even intervals, each capacitor receiving portion 28 is formed along the circumference of the turntable 26 and the radius of the turntable 26 And a notch or recess extending inward along the direction. Each capacitor accommodating portion 28 has a lateral opening that is formed on the circumference of the turntable 26 to move to the capacitor accommodating position according to the rotation of the turntable 26. It has a lateral opening that can move to the capacitor receiving position. In the capacitor receiving position, the capacitor semifinished product 32 from the capacitor assembly device (not shown) is received in the capacitor receiving portion 28 through the channel 30 extending from the capacitor assembly device to the capacitor receiving position. Channel 30 is generally the automatic filling and curing device 10 of the present invention from the capacitor assembly device to transfer the capacitor semi-finished product (32) manufactured in the capacitor assembly device to the automatic filling and curing device 10 of the present invention It is designed to extend.

In a suitable embodiment of the present invention, the channel 30 is formed with an end opening positioned at the capacitor receiving position exactly corresponding to the circumference of the turntable 26, and as the turntable 26 rotates in the direction of arrow A, The capacitor receiving portions 28 sequentially move to the capacitor receiving position, and then temporarily stop at the capacitor receiving position to receive the capacitor semifinished product 32 therein by aligning the lateral opening thereof in line with the end opening of the channel 30. I can do it. To this end, the turntable 26 is capable of transferring the capacitor semifinished product 32 between the channel 30 and the turntable 26 and between the turntable 26 and the capacitor carriage 34 so that the capacitor transfer position as well as the capacitor It is designed to stop the rotation at a predetermined angular position corresponding to the receiving position.

Capacitor supply 12 includes a plurality of capacitor carriages 34, which take the form of elongate members having one or more channels 36 extending in the longitudinal direction. According to a suitable embodiment of the present invention, each capacitor carriage 34 has two channels 36 that are parallel to each other and separated by a powder wall 38 as shown in the figure. The capacitor carriage 34 is driven by the first driving means 40 and is movable along the first path. The capacitor carriage 34 is guided by the first rail 41 (FIGS. 8 to 14) and the hardening oven ( 14) (i.e., in the first direction indicated by arrow B in FIGS. 1 and 5), so that the capacitor carriage 34 is sequentially positioned at the capacitor transfer position, Each channel 36 of the stage 34 is aligned with the lateral opening of the capacitor receiver 28 to receive the capacitor semifinished product 32 from the capacitor receiver 28 as indicated by arrow C in FIG. In the closed state, ie, at the capacitor transfer position. An apparatus 42 movable in the direction of arrow C is provided to move the capacitor semifinished product 32 from the receiving portion 28 of the turntable 26 to the channel 36 of the capacitor carrier 34.

Each channel 36 (or each capacitor carriage 34) has a predetermined length that can accommodate a predetermined number of capacitor semifinished products 32, as shown in FIG. When each channel 36 of the capacitor carriage 34 is completely filled with the capacitor semifinished products 32 by the operation of the device 42, the first driving means 40 drives to remove the capacitor carriage 34. On one rail 41 move (arrow B) along the first path towards the curing oven 14, whereby the next capacitor carriage 34 is shown as shown in FIG. It is located in the capacitor transfer position of the turntable 26 to accommodate. The capacitor carriage 34, which is completely filled with the capacitor semifinished products 32 supplied from the turntable 26, is moved by the first driving means 40 in the direction of arrow B toward the curing oven 14. Accordingly, the capacitor carriage 34 and the capacitor semifinished products 32 carried thereon are moved into the curing oven 14. At the same time, the next capacitor carriage 34 is driven by suitable means (such as the collecting device 22 to be described later) to move to the capacitor transfer position of the turntable 26 as shown in FIG. .

According to the present invention, the curing oven 14 is designed to have a two-layer configuration (7 to 11) of the upper and lower layers so as to reduce the space occupied. Each layer of the curing oven 14 has a first end for entering the capacitor semifinished product 32 into the curing oven 14 and a second end opposite the first end for discharging the cured capacitor semifinished product. have. The curing oven 14 includes a first elevator 44 interlocking with the first tunnel and a second elevator 90 interlocking with the second tunnel to transfer capacitors between the upper and lower layers of the curing oven 14. An elevator type conveying means is provided. According to the present invention, one layer of the first tunnel of the curing oven 14 in the first path (for example, the lower layer of the first tunnel as shown in the drawing) may guide the capacitor semi-finished product 32 into the curing oven 14. Determined by the first rail 41 on the first path, the other layer of the first tunnel can discharge the primary cured capacitor semi-finished product (hereinafter referred to as "32a" for distinction) from the curing oven 14. It is determined by the second rail 45 (FIGS. 5-11) of the first path (see FIGS. 6-11). The first rail 41 and the second rail 45 constitute a first portion (lower portion) and a second portion (upper portion) of the first path. The total length of the upper and lower layers of the curing oven 14 is determined by the capacitor semifinished product 32 being transferred by the capacitor carrier 34 moving through the first rail 41 and the second rail 45. It is a length capable of sufficiently curing the resin filled in 32).

For example, a resistance in the curing oven 14 is maintained to maintain the temperature inside the tunnels of the curing oven 14 at a room temperature or an appropriate curing temperature higher than the ambient temperature so as to cure the thermosetting resin in the capacitor semifinished product by high temperature. Heating elements (not shown) such as heating elements of a type or induction type or a hot air flow generator are provided. Of course, it is also possible to use other materials having suitable electrical properties, such as materials curable by ultraviolet rays, in place of the above-mentioned thermosetting materials. In this case, the curing oven 14 must be provided with ultraviolet light source (s) instead of heating elements.

The capacitor semifinished products 32 move together with the capacitor carriage 34 in the lower layer of the oven 14 via the first end of the curing oven 14 in the direction indicated by the arrow B along the first path. The first drive means 40 continuously moves the capacitor carriage 34 into the curing oven 14, whereby the capacitor carriage 34 is moved into the curing oven 14 as shown in FIG. 7. The first end is pushed toward the second end. The capacitor carriage that has reached the second end of the curing oven 14, together with the capacitor semifinished products 32 loaded thereon, is held by the first elevator 44 as shown in FIGS. 8 and 9 by the curing oven 14.

As shown in FIGS. 10 and 11, the first elevator 44 includes a curing oven 14 for the capacitor semi-finished product 32 transferred from the lower layer to the upper layer of the curing oven 14 by the first elevator 44. The second driving means 46 is provided for moving (in the direction of the arrow D) from the second end to the first end. The thus moved capacitor carriage 34 and the capacitor semifinished product 32 enter the curing oven 14 again (but at this time enter the upper layer of the curing oven 14) and are further heated by the curing oven 14. As a result, the resin is further cured.

Operation of the second driving means 46 and the first elevator 44 is primarily performed by moving the plurality of capacitor carriages 34 sequentially along the second rail 46 toward the first end of the curing oven 14. The cured capacitor semifinished product 32a is interlocked with the first driving means 40 to discharge the cured capacitor semi-finished product 32a from the curing oven 14 at the first end of the upper layer of the curing oven 14. Thus, the capacitor semifinished products 32a move along the second rail 46 to finally reach the front discharge position as described later.

According to the present invention, the curing oven 14 is sufficiently heated as the capacitor semi-finished product 32 passes through the upper and lower layers of the curing oven 14 (ie, the first part and the second part of the first path) and its resin. Has dimensions that allow it to harden sufficiently.
