1 schematically shows an assembly apparatus for a box-type capacitor constructed in accordance with the present invention, which includes three supply systems for receiving three materials and supplying the materials. These three supply systems include an insulated casing supply system 10, a capacitor element supply system 12, and a lead wire supply system 14 (see FIG. 12) to provide a plurality of insulated casings 16 and a plurality of capacitor elements (see FIG. 12). 18) and two lead wires 20 are respectively supplied to the assembly apparatus of the present invention to be assembled together to form a box capacitor. According to the present invention, the box type capacitor assembling device further includes soldering means 22 for soldering the lead wire 20 to the capacitor element 18. For the sake of brevity, a wire bonded element, which is the element 18 that is leaded by the lead wire 20, is indicated by reference numeral 24. Thus, the wire bonded element 24 is composed of a terminal lead (wire portion) and an element body (body portion).

In addition, the assembly device of the present invention accommodates the insulating casing 16 in the insulating casing supply device 10 and the element 24 in the soldering means 22 and stores the received element 24 in the insulating casing ( 16, consisting of a rotatable assembly workstation or process workstation 26 assembled to provide the desired semi-product. Before being a final capacitor product, the above-described semifinished product requires an additional process such as a heating process for curing the resin. This additional process is irrelevant to the present invention and can be easily carried out by a known apparatus, and thus, detailed descriptions thereof will be omitted except where necessary to understand the present invention.

In addition, the assembly apparatus of the present invention further includes a conveyor system 28 for advancing the wire bonded element 24 from the soldering means 22 to the assembly workstation 26 to proceed with the assembly operation of the box capacitor. .

By the assembling operation according to the present invention, the capacitor elements 18 are supplied to the soldering means 22 in a manner to be supplied one by one in the capacitor element supply system 12, and at the same time, the two lead wires 20 are A lead supply system 14 is supplied to the soldering means 22 to solder the element 18 with a lead wire 20 that is bent into a V shape and cut to an appropriate length. A wire bonded element 24 is thus formed, which has a terminal lead formed by a lead wire having a V-shaped bend. The element 24 is then conveyed by the conveyor system 28 to the assembly workstation 26.

The assembly workstation 26 receives the insulated casing 16 in a casing accommodating step in the insulated casing supply system 10 in a manner of accommodating one by one and detects / positions the insulated casing 16 in this casing accommodating step. A capacitor semifinished product having a part of a box-shaped capacitor composed of a plurality of casing holding sheets 30 which can be moved continuously to a determination step, a resin injection step, an element insertion step, an element step and a collection step is assembled together. It will be supplied to other devices that add additional processing to the semifinished product.

In the above detection / positioning step, the casing 16 in which the inner space with the open surface is formed is detected to confirm that the open surface of the casing is placed in the correct direction. In this embodiment, the open surface of the casing 16 is arranged to face upward, so that a shape similar to a container is formed in the casing holding sheet 30. In addition, the casing 16 is suitably pressed and disposed harder in the casing holding sheet 30.

In the resin injecting step, a predetermined amount of resin is injected into the inner space of the casing 16 through the upwardly facing open surface. Since the open face faces upward, the casing 16 can accommodate and hold resin.

In the device insertion step, the wire-bonded device 24 conveyed from the soldering means 22 by the conveyor system 28 is suitably disposed in the casing 16 through the opening surface, so that the device 24 Is at least partially immersed in the resin with the terminal leads partially protruding out of the casing 16. Since the respective terminal leads, which can slide and be accommodated in guide slots (not shown) respectively formed on two inner opposing surfaces of the casing 16, are bent in a V shape, the element 24 is connected to the casing ( 16 is suitably disposed and guided deeply into the resin in the casing 16.

In the element pressing step, the wire bonded element 24 is further pressed against the resin in the casing 16 so that the element 24 can be positioned to a predetermined depth in the resin. Thus, the capacitor semifinished product indicated by reference numeral 32 in the drawing is formed.

The semifinished product 32 thus formed is released from the casing holding sheet 30 of the assembly workstation 26 through the feed-out panel 34 to be properly collected in the collecting step and passed on to the subsequent process. In general, subsequent processing of the semifinished product 32, including at least a heating step, will facilitate curing of the resin and additionally add the amount of resin in the casing 16 (mainly semi-finished product 32) to the second resin injection process. It can be charged to be able to completely fill the inner space of the casing (16). It is also possible to cure the additionally filled resin by an additional heating step, which completes the manufacture of the final product of the boxed capacitor.

The present invention is to improve the mechanical portion than the electrical and control portion of the assembly device of the box-type capacitor, the electrical and control portion is omitted below. Although the electrical / control portion of the box-type capacitor assembly device is not described in detail herein, those skilled in the art can easily use various control devices that are widely used or known, so that predetermined information about the electrical / control portion may not be known. However, it can be easily obtained from related information sources.

The operation process of the mechanical parts of the box-type capacitor assembly device according to the present invention is as follows. First, as shown in FIG. 2, the rotatable assembly workstation 26 has a circular turntable 36 having a circular outer circumferential surface driven by a suitable power / control device (not shown), which turntable As shown by arrow A in FIGS. 1 and 2, the rotation is about the central axis 38. The workstation 26 is rotated at a constant angular speed in an intermittent manner in the casing supply step, detection / positioning step, resin injection step, device insertion step, device pressurization step and collection step (collective meaning in the process step). It is desirable to be controlled to temporarily store for a predetermined time in order to temporarily stop and allow the operation performed in all process steps to be completed.

The turntable 36 of the assembly workstation 26 has a plurality of notches spaced at equal intervals along the outer circumferential surface, which notches extend in the radial direction of the turntable 36 to have a predetermined length along the radius. . Each notch consists of one of the casing holding sheets 30 of the assembly workstation 26. In general, two adjacent notches 30 are formed by the supply ratio of the supply systems 10, 12, 14 and the time interval of the turntable 36 intermittently stopped by the process step and the rotational speed of the turntable 36. The angle between) is determined. Each notch 30 extending along the radius of the circular turntable 36 has an open face upwardly open and side openings are formed on the outer edge of the turntable 36. The side opening of the notch 30 is arranged to correspond to the casing supply step to accommodate the insulating casing 16 supplied to the casing supply system 10. The notch 30 is of sufficient size to accommodate and hold the insulated casing 16, but is not so small that the casing 16 should be held firmly in the notch 30.

In addition, as shown in FIG. 1, the casing supply system 10 includes a round vibrating feeder 40, which is a cylindrical container in which a plurality of insulating casings 16 are laid down. The casing 16 lowered into the vibration feeder 40 is randomly oriented by the vibration generated in the feeder 40, and this casing 16 moves the slope 42 inclined upward by the designated method. The cylindrical side wall of the vibration feeder 40 is formed with an outlet at the highest position of the slope 42, and a linear channel 44 extends to the outer circumferential edge of the turntable 36, thereby assembling the workpiece. In the casing feeding step of the station 26, the casings 16 are received from the feeder 40 of the cylindrical container. When the notch 30 is stopped in the casing supply step, the side opening of the notch 30 is aligned with the spaced end of the linear channel 44 and the casing 16 moved along the channel 44 is the side opening. It is conveyed to the notch part 30 through. As described above, the casing 16 is accommodated in the notch portion 30 and is formed in a container-like structure with the open surface facing upward.

The linear casing feed channel 44 extends obliquely downward from the outlet of the vibratory feeder 40 toward the casing feed step and is provided with a belt conveyor (not shown), so that the casing feed step is fed from the outlet of the feeder 40 to the casing feed step. Movement of the insulating casing 16 is made easy.

The round vibrating feeder and belt conveyor system are well known and will be omitted herein since they will be readily appreciated by those skilled in the art.

As described above, the notches 30 are spaced at equal intervals along the periphery of the turntable 36 so that the insulating casing 16 in the casing supply system 10 can be easily attached to the notches 30. The turntable 36 is accommodated and controlled to stop for a while in each of these spaces. Thus, each time the turntable 36 is stopped, one of the notches 30 is aligned with the linear channel 44 of the casing supply system 10 to easily accommodate one casing 16.

After the insulating casing 16 is received and held in the casing holding sheet (notch) 30, the casing 16 moves with the turntable 36 and continues at each process step in which the turntable 36 is stopped. To stop. The two stops of the casing holding sheet 30 and the insulating casing 16 are made in the detection / positioning step and the resin injection step, in which the detection / positioning device 46 and the resin injection device 48 A casing 16 is provided to detect and position the casing 16 in the holding sheet 30 and to fill the positioned insulating casing 16 with resin.

As shown in FIG. 2, the detection / positioning device 46 installed in the detection / positioning step has a base 50 rotatable reciprocally with respect to the turntable 36 of the assembly workstation 26. The base 50 rotates about the shaft 52 on which the driving rod 56 pivoted on the shaft 54 is mounted. The two shafts 54, 52 are spaced apart from each other by a suitable distance, and the shaft 54 is located farther from the turntable 36 than the shaft 52, so that the rods mounted on the appropriate power / control means (not shown) ( The base 50, which is the reciprocating motion of 56, rotates about an axis 52 so as to face or be spaced apart from the turntable 36. The base 50 has a fixedly mounted detection / positioning bar 58, and when the notch 30 is moved to the detection / positioning step, the lower end of the bar 58 rests on the notch 30. Are placed correctly. Thus, when the base 50 rotates about the axis 52 in the reciprocating manner, the bar 58 is moved up and down by a predetermined distance in the detection / positioning step. The bar 58 when the casing 16 is not disposed correctly in the notch 30, that is, when the open surface of the casing 16 does not go upward and the non-open side of the casing goes upward. Travel distance becomes shorter. This results in an incorrect orientation of the casing 16 in each notch 30.

In addition, the insulating casing 16 is moved by a belt conveyor (not shown) through the casing supply channel 44 so that the casing 16 is accommodated in each notch 30 on the turntable 36. It may not be arranged by the notch 30 so that it can be held firmly. Since this causes a problem in a continuous process, the downward movement of the bar 58 mounted on the detection / positioning device 46 is designed to contact the casing to pressurize the casing 16. Thus, by pressing the casing 16 below the notch 30, the insulating casing 16 is more firmly and accurately disposed in the notch 30. Once the base 50 is rotated away from the turntable 36, the bar 58 is separated from the casing 16 and moved away so that further rotation of the turntable 36 does not affect the bar 58. Does not.

The base 59 of the resin injection device 48 has an injector 66 fixedly mounted with a tubular member 68 to a pressurized hose connected to a resin feeder (not shown), and supplied from the hose 68. It consists of an injection nozzle 70 which guides the resin into the insulating casing 16 in the resin injection step. As with the detection / positioning device 46, the insulating casing 16 is moved together with the turntable 36 of the assembly workstation 26 to be temporarily stopped and positioned below the resin injecting device 48. Resin injection step. At this time, the injector 66 is driven by the driving rod 60 and moved downward toward the casing 16 as shown by arrow 4 in FIG. 4. Thus, the nozzle 70 is disposed exactly opposite to the insulating casing 16 (see FIG. 4). Resin supplied from the resin feeder to the injector 66 by a suitable control / pumping device (not shown) is introduced into the insulating casing 16 through the injector 66. As described above, the open face of the insulating casing 16 is upward and is formed in a container shape, and the resin injected through the nozzle 70 is transferred to the casing 16 through the open face of the casing 16. The resin filled in the casing 16 by a predetermined level will generally occupy about 70% to 80% of the internal space of the insulating casing 16. After the resin is injected, the injector 66 is moved together with the base 59 by the driving of the rod 60, which is separated from the casing 16 and moved upward (see FIG. 3) to return to the initial position. . Therefore, the rotation of the turntable 36 and the casing 16 is not affected.

In the above resin injecting step, the casing 16 is in the element inserting step in which the element inserting device 72 (see FIGS. 1, 2, 7, 8, 10, and 11) is disposed after resin is filled in the casing 16. Is continuously moved with the tentable 36. As shown in the figure, the element insertion device 72 has a pair of jaws 74 driven by suitable power / control means (not shown), in order to change the space therebetween (ie, two jaws). Relative to one another) to open and / or shield 74. The jaw 74 is mounted on the movable base 76 and moves in line with arrows C and D shown in FIGS. 10 and 11, with wire-bonded elements 24 moving away from and close to the conveyor system 28. Will accept. In particular, an element insertion device 72 is arranged such that the device 72 is engaged in the conveyor system 28 as it is moved in a first direction (eg, arrow C direction), as shown in FIG. 10. The jaw portion 74 approaches and engages the element 24 carried by 28. Once the device insertion device 72 receives the device 24 in the conveyor system 28, the device 72 is moved in a second direction opposite the first direction (arrow D in FIG. 11) to move the device. It will have the element 24 located in the casing 16 arranged in the insertion step. The device 24 has two terminal leads each received and soldered into guide slots formed in the casing 16 so that the device 24 is properly guided to the insulating casing 16. Thus, as shown in FIG. 11, at least a portion of the terminal leads exposed to the outside of the casing 16 is immersed in the resin. The jaw portion 74 is opened and separated from the wire bonded element 24 so that the element 24 is accommodated in the casing 16. According to a preferred embodiment of the present invention, the engagement of the device 24 with the jaw portion 74 is made in the terminal leads (wires) of the device rather than the device body, so that they are close to each other as shown in FIGS. 8, 10 and 11. When the jaw portion 74 is caught by the terminal lead of the device (24).

Referring again to FIGS. 1 and 2, after the wire bonded element 24 is accommodated in the insulating casing 16, the turntable 36 of the assembly workstation 26 is mounted with the element press device 78. It is moved towards the pressing step (see FIGS. 5 and 6). Therefore, the element 24 accommodated in the casing 16 is pressed further inward at a predetermined position toward the resin in the casing 16, so that subsequent processes are easily performed. As shown in FIGS. 5 and 6, the element pressing device 78 is pivotally secured to a base 86 secured to the shaft 82 and to a shaft 86 of the shafts 82, 86 suitably spaced from each other. Consisting of a drive rod 84 that is pivotable relative to the base 80 so that the base 80 is driven in a reciprocating motion by an appropriate power / control device (not shown). ) Rotates around each other.

In addition, the element pressing device 78 is fixed to the base 80, and when the casing 16 is in the element pressing step, the pressure bar 88 is disposed to correspond to the position where the insulating casing 16 is disposed. It is provided with. Accordingly, when the base 80 is driven by the driving rod 84, the base rod 80 rotates about the shaft 82 so that the pressure bar 88 is moved in the direction of arrow E of FIG. 6 to the casing 16. Close. Accordingly, the lower end of the bar 88 comes into contact with the element 24 disposed in the casing 16, so that as shown in FIG. 6, the element 24 is casing 16 to a predetermined depth during the rotation of the base 80. Pressurized by the resin in the inside. Once the pressurization is completed, the pressure bar 88 is spaced apart by the reverse movement of the drive rod 84, the lower end of the bar 88 is separated from the casing 16. This operation does not affect the rotational movement of the turntable 36, as shown in FIG.

In the present invention, as shown in Figs. 1 and 2, the detection / positioning device 46 of the detection / positioning step is similar to or the same as the element pressing device 78. Thus, an additional understanding of the detection / positioning device 46 can also be seen in FIGS. 5 and 6. However, the detection / positioning device 46 need not be similar or identical to the element pressing device 78, and the casing in the notch or casing holding sheet 30 of the turntable 36 of the assembly workstation 26. (16) Any device or means capable of detecting and positioning can be used to replace the detection / positioning device.

In FIGS. 7 and 8, which show the conveyor system 28 applied to the box-type capacitor assembly device of the present invention, a part of the conveyor system 28 is omitted for brevity of the drawing. As can be seen in this figure, the conveyor system 28 consists of an endless chain 90 which is looped around two spaced sprockets 92 and 94 (also see FIG. 1). The first sprocket 92, which is one of the sprockets, is disposed close to the device insertion step or the device insertion device 72, and the second sprocket, which is the other one, is disposed close to the soldering device or the soldering means 22. When the chain 90 is moved in the direction of the arrows F and G, the element 24 accommodated in the soldering means 22 is moved forward with the movement of the chain 90 to a predetermined position which is an element insertion step.

As shown in the figure, the lower portion of the chain 90 (the portion moved in the direction of arrow G) is moved from the soldering means 22 to the element inserting device 72 in the element insertion step, and the upper portion of the chain (arrow G The portion moved in the direction of the arrow F opposite to the direction) is preferably arranged to move from the element insertion device 72 to the soldering means 22.

The chain 90 has a plurality of element holders 96 which are mounted spaced at equal intervals along the chain 90. Each element holder 96 has a base 98 fixed to the chain 90, the base being spaced apart from the chain 90 to be mounted to move as the chain moves and spaced apart from each other to form an opening. It is provided with two jaw portion (100). The two jaws 100 of each element holder 96 are controlled and driven by suitable control / drive means (not shown) so that they can be moved relative to each other to change the space formed therebetween. Therefore, it is possible to pick up and hold the wire bonded element 24 by the two jaw portion (100). The element holder 96 moves with the chain 90 in the direction of the arrow F and is close to the soldering means 22, so that the element holder 96 is located at the element turntable 102 located adjacent to the soldering means 22 (soldering means 22). Device 24), which is transferred by the device 24, to the device insertion device 72.

The element turntable 102 is controlled by control / drive means (not shown) and rotates about an axis 104, with a plurality of jaws 106 spaced along the outer circumferential surface of the turntable 102. The jaw portion 106 is moved to the element supply position where each pair of jaw portions 106 receive the capacitor element 18 in the element supply system 12 by the rotation of the element turntable 102. Therefore, when the device turntable 102 rotates about the axis 104, the lead wire 20 can be soldered to the device 18 by soldering means 22 to obtain a wire bonded device 24. The device 18 is moved to the soldering position. In addition, as shown in FIG. 9, the element 24 is transferred from the jaw portion 106 of the turntable 102 to the element holder 96 of the chain 90 by the rotation of the element turntable 102. The bonded element 24 is directed to the position ()).

As described above, according to the operation of the turntable 102, the wire part (terminal lead) together with the body of the element 24 in which the jaw portion 100 of each element holder 96 is disposed outside the jaw portion. The element holder 96 of the chain 90 is activated to hold and hold the element 24 at. Thus, when the element holder 96 is moved below the chain 90 (in the direction of arrow C), the body of the element 24 is positioned below the chain 90. 7, 10 and 11, the chain 90 is controlled by an appropriate control / drive means (not shown) so that the element 24 held in the element holder 96 together with the chain 90 The chain 90 is stopped once when moved to the insertion step. At the same time, as described above, as shown in FIG. 10, as the device insertion device 72 moves in the direction of the arrow C, that is, upward, the jaw portion 74 is moved closer to the device 24. It is located on the opposite surface respectively. In the control state of the control / drive means (not shown) of the turn portion 74, the jaw portion 74 is driven while picking up the terminal lead of the wire bonded element 24, so that the element holder of the chain 90 ( 96, wire-bonded device 24 is received.

As described above, when the jaw portion 74 picks up the terminal lead of the element 24, the element insertion device 72 is moved downward so that the wire-bonded element 24 in the element insertion step is turnedtable 36 Facing the casing 16 disposed on each casing holding sheet 30. Thus, the element 24 is disposed in the casing 16 and immersed in the resin in the casing 16. In this embodiment, the holder 96 such that the device body is inside the holder (when the device holder 96 is at the bottom of the chain 90) and a terminal lead having a V-shaped bend is positioned on each device body. Since the element 24 in the array is oriented, the element 24 held by the tuck portion 74 of the element insertion device 72 at the terminal lead, as shown in FIG. 8, is directly inside the insulating casing 16.

The reel 110 is a winding of a linear conductor (lead wire indicated by reference numeral 20) with suitable rigidity. The leading ends of the two lead wires 20 released from the road 110 are guided by guide rollers or idler rollers 112 and extend through the lead wire straightening device 114. The lead wire straightening device 114 has a plurality of straightening rollers 115 arranged to guide and straighten the extending lead wires 20 so that the wires are straightened by passing the lead wires 20 through the rollers. It is linear. Lead wire straightening device 114 of this kind is well known in the art, and further description thereof will be omitted.

Thereafter, the tip of the lead wire 20 corrected by the lead wire advancing device 116 is extended to advance the predetermined length of the lead wire 20 toward the soldering position of the soldering means 22. That is, each operation cycle of the advancing device 116 is a predetermined distance corresponding to the predetermined distance toward the soldering means 22 and the predetermined length of the lead wire 20 moved by the advancing device 116. The front end of the lead wire is moved as much as possible. As shown in FIGS. 13-15, the lead wire advancement device 116 has a fixed or anchored wire holder 118 and a movable wire holder 120 (commonly referred to as a wire holder). The wire holder is driven by appropriate control / drive means 144 to catch or release the lead wire 20 extending through the wire holders 118 and 120. The movable wire holder 120 is further controlled and driven by a control / drive means (not shown) to be reciprocally movable within a predetermined distance range between the fixed wire holder 118 and the soldering means 22. . The moving range of the movable wire holder 120 is determined by two spaced apart restriction blocks 122 and 124.

Thereafter, the movable wire holder 120 is moved in the direction of the arrow K in FIG. 15, that is, as shown in FIG. 124). In addition, since the lead wire 20 is fixed by the fixed wire holder 118, when the movable wire holder 120 is moved from the first limit block 122 to the second limit block 124, the wire ( 20) will remain fixed. As the above process is repeated, the wire 20 is continuously supplied from the wire reel 110 to the soldering means 22 by the forward device 116, and the distance of the forward operation of the forward device 116 is It is determined by the moving distance of the movable wire holder 120 (ie, the distance between the two restriction blocks 122, 124). Thus, the distance between the two limiting blocks 122 and 124 can be adjusted, so that, if necessary, the terminal of the wire bonded device 24 by adjusting the position of the wire cutting device 158 relative to the soldering means 220.
