Description

  The present invention relates to a small component member aligning tool, a small component member aligning device, a small component member arranging method, and an electrode forming method, and more specifically, a plurality of small component members as desired in a holding jig. Small component member alignment tool, small component member alignment device, small component member arrangement method, and a plurality of small component members formed in a desired manner in a movable standing upright state The present invention relates to a method for forming an electrode.

  Conventionally, for example, a small component such as a chip capacitor is manufactured by using a holding jig provided with an adhesive portion or an adhesive surface capable of adhesively holding a member for a small component capable of manufacturing a small component on its surface. The At this time, as a method for sticking and holding a plurality of small component parts and / or small parts (hereinafter, sometimes referred to as small part members) on the adhesive portion or adhesive surface of the holding jig, a plurality of small parts are used. An alignment tool or an alignment device that arranges members for use at predetermined intervals is used. In order to manufacture a small part using an aligner, an aligner, or the like, a plurality of small part members need to be aligned at predetermined intervals, and are further aligned by an aligner, an aligner, or the like. It is necessary for the adhesive part or the adhesive surface of the holding jig to be adhesively held while maintaining the aligned state.

  As an example of an aligning device for aligning small component members and the like, for example, an electronic component supply unit provided in an apparatus used for an end electrode forming method in a chip-shaped electronic component can be cited (see Patent Document 1). The alignment cartridge provided in the electronic component supply unit is “an alignment block that has a large number of through-holes for receiving chip-shaped electronic components and aligns the chip-shaped electronic components in an upright state, and a lower surface of the alignment block. It has a reference block having a flat surface that abuts and aligns the lower end position of the chip-like electronic component, and a holder that integrates the alignment block and the reference block ”(see paragraph No. 0099 of Patent Document 1 and FIG. 23, etc.). .)

  However, since the alignment cartridge described in Patent Document 1 is configured by integrating the alignment block and the reference block, the chip-shaped electronic component that has been transferred to the through-hole of the alignment block is moved from the through-hole by vibration or the like. It may jump out and drop out. In addition, after removing the chip-shaped electronic component remaining on the alignment block after the chip-shaped electronic component has been transferred into the through-hole, if the alignment block is tilted, the chip-shaped electronic component will also jump out of the through-hole and drop off. There are things to do. Therefore, in this alignment block, the plurality of chip-like electronic components cannot be aligned as desired, and the plurality of chip-like electronic components are aligned as desired in the adhesive such as the first film. In some cases, pasting was not possible.

  As an alignment tool or alignment apparatus that solves such problems, for example, “a holding jig having an adhesive surface on its upper surface and a number of through-alignment holes for aligning and transferring chip-type electronic components are provided. An alignment plate disposed on the holding jig with a clearance less than the height in the transfer direction of the chip-type electronic component from the holding jig, and a supply for supplying a large number of chip-type electronic components on the alignment plate Means for transferring the chip-type electronic component supplied on the alignment plate to each alignment hole, and a transfer assisting means for vibrating or swinging the alignment plate to the alignment hole. A chip-type electronic component alignment and holding device characterized in that one end face of the transferred chip-type electronic component is adhesively held by the adhesive surface of the holding jig (claim 1 of Patent Document 2). Equality .).

  However, in the alignment holding device described in Patent Document 2, the alignment plate is disposed on the holding jig with a clearance less than the height in the transfer direction of the chip-type electronic component from the holding jig, and is transferred into the alignment hole. The chip-type electronic component is adhesively held on the adhesive surface of the holding jig by its own weight. Therefore, since the clearance between the alignment plate and the holding jig needs to be adjusted to be very small, it is expected that adjustment of the clearance is difficult. In addition, since the chip-type electronic components that have been transferred into the alignment holes are small and light, the adhesive force held by the self-weight on the adhesive surface of the holding jig is small, and as a result, when removing the alignment plate from the holding jig In addition, it is sufficiently expected that the chip-type electronic component is inclined or falls.

There is no non-uniformity such that the member cannot be sucked and stored. Therefore, the small component member aligning tool 10A can align a plurality of small component members in an upright state that can be transferred to the holding jig as desired.

  In addition to the above-described effects, the small component member aligning tool 10A has a suction hole 15 that communicates with the storage hole 12 and opens on the back surface of the flat plate portion 11. Therefore, the small component member aligning device 30 described later. Is easily incorporated into the aligner installation member 33, and the storage hole is formed by sucking the gas in the closed space 34 formed by the flat plate portion 11, that is, the back surface of the small component member aligner 10A and the aligner installation member 33. The inside of 12 can be sucked uniformly.

  As shown in FIG. 3, the small component member aligning tool 10 </ b> B according to another embodiment of the present invention includes a communication path 17 in which the suction holes 15 communicate with the plurality of storage holes 12, a communication path 17, Except for having a suction hole main passage 16 communicating with the back surface of the flat plate portion 11, it is configured in the same manner as the member aligner 10A for small parts. That is, the suction hole 15 opens on the back surface of the flat plate portion 11, and communicates the suction hole main passage 16 extending toward the storage hole 12 and the bottom surface 14 of the suction hole main passage 16 and the storage hole 12. And a communication passage 17 having a diameter smaller than the diameter of the storage hole 12.

  As shown in FIG. 3, the diameter of the suction hole main passage 16 may be a size that does not communicate with the adjacent suction hole main passage 16, and is adjusted to an arbitrary size in consideration of suction efficiency. Further, the length is not particularly limited.

  Although the communication path 17 should just have a diameter smaller than the diameter of the storage hole 12, the virtual circumscribed circle 7 circumscribing each corner in the cross section perpendicular | vertical to the major axis direction of the member for small components (FIG. 6 ( As in the case of the suction hole 15 of the small component aligner 10A, it is preferable that the diameter be slightly smaller than the diameter of b).

  This small part member aligning tool 10B has the effect of the small part member aligning tool 10A of the above-described embodiment, and also has the effect of good suction efficiency.

  As shown in FIG. 4, the small-part component aligning tool 10C according to another embodiment of the present invention includes a first flat plate portion 11A in which a plurality of storage holes 12 are perforated in a predetermined arrangement, The first flat plate portion 11 </ b> A is stacked, and a plurality of suction holes 15 are provided in the same arrangement as the storage holes 12. The small component member alignment tool 10C preferably has an axial line so that each of the storage holes 12 perforated in the first flat plate portion 11A and each of the suction holes 15 perforated in the second flat plate portion 11B communicate with each other. The first flat plate portion 11A and the second flat plate portion 11B are stacked so as to communicate with each other so that one end of the small component member protrudes into each storage hole 12. One member can be stored one by one. This small component member aligning tool 10C is similar to the small component member aligning tool 10A of the above embodiment except that the flat plate portion 11 is divided into a first flat plate portion 11A and a second flat plate portion 11B. It is constituted similarly. The small component member aligning tool 10C has the effect of the small component member aligning tool 10A of the above-described embodiment, and further, by selecting the storage holes 12 or the suction holes 15 in the flat plate portions 11A and 11B, It has the effect of being easily manufactured.

  The small-part component aligners 10A to 10C are manufactured, for example, by cutting out the flat plate portion 11 in which the storage holes 12, the suction holes 15 and the like are formed by using the above-described material.

  Each of the storage holes 12 in the small component aligning tools 10A to 10C has an inner surface 13 having a uniform diameter from the bottom surface 14 to the opening, but FIGS. 5 (a) and 5 (b). ), The storage hole 12 preferably has an inner surface whose diameter gradually increases from a predetermined position toward the opening. As a result, when the opening of the storage hole 12 is formed on a tapered surface with a gradually increasing diameter, the small component member is guided by the tapered surface and can be easily stored in the storage hole 12, and the small size can be reduced. The component member can be smoothly taken out from the storage hole 12. As such a storage hole 12, for example, as shown in FIG. 5A, the storage hole 12A having an inner surface 13A having an opening formed in a mortar-shaped tapered surface 18A is shown in FIG. 5B. As described above, a storage hole 12B having an inner surface 13B formed with a tapered surface 18B having a curved surface is preferable.

  The member alignment tool for small parts according to the present invention is not limited to the above-described embodiments, and various modifications can be made within a range in which the object of the present invention can be achieved. For example, the plurality of storage holes 12 all have the same shape, that is, the inner surface 13, but may have different shapes. For example, a storage hole formed from an inner surface having a uniform diameter from the bottom surface to the opening, a storage hole having an inner surface in which the opening illustrated in FIG. 5A is formed in a mortar-shaped tapered surface, The opening shown in 5 (b) may be mixed with a storage hole having an inner surface formed on a curved tapered surface.

  In addition, the small component member alignment tool 10B includes the flat plate portion 11 in which the storage hole 12, the suction hole main passage 16, and the communication passage 17 are formed. The flat plate portion, the second flat plate portion in which the communication passage is perforated, and the third flat plate portion in which the suction hole main passage is perforated may be laminated in this order.

  Further, the suction holes 15 in the small component aligning tools 10A to 10C are formed independently so as to communicate the back surface of the flat plate portion 11 or 11B and the storage hole 12, but in this invention, The suction holes do not need to be formed independently. For example, the plurality of storage holes may be suction grooves that can be sucked together.

  In each of the small component aligning tools 10A to 10C, the storage holes 12 and the suction holes 15 are arranged at equal intervals in the vertical and horizontal directions. However, the arrangement of the storage holes and the suction holes is not limited to this arrangement. An arbitrary arrangement such as a concentric arrangement or a spiral arrangement can be selected in accordance with the application, apparatus, type, size, etc. of the small component member.

  In the small component aligning tools 10A to 10C, the flat plate portion 11 is formed in a rectangular shape, but the flat plate portion only needs to have a shape suitable for manufacturing a small component. According to the apparatus etc. in which the member alignment tool for small parts is used, it is set as arbitrary shapes. For example, the flat plate portion includes a plate-like body such as a polygon such as a square, a rectangle, a pentagon, and a hexagon, a circle, an ellipse, an indeterminate shape, or a combination thereof.

  A member alignment apparatus for small parts according to the present invention will be described. As shown in FIG. 7, the small part member aligning device 30 of one embodiment according to the present invention and the small part member aligning tool 10 and the suction hole 15 (not shown) of the small part member aligning tool 10. And suction means 31 for sucking the inside of the storage hole 12 (not shown), and a vibration means 32 for applying vibration to the small component aligning tool 10. The small component member aligner 10 is the same as the small component member aligner 10A.

  As long as the suction means 31 can suck the inside of the storage hole 12 through the suction hole 15 of the small component member aligning tool 10, the arrangement place thereof is not particularly limited. For example, in the small component member aligning apparatus 30 shown in FIG. 7, the suction means 31 is connected in a closed space 34 formed by an aligner installation member 33 and a small component member aligner 10 described later, By exhausting the closed space 34, the inside of the storage hole 12 is sucked. The suction means 31 may be any device that can exhaust the inside of the closed space 34, and for example, a normal suction pump or the like can be used.

  The vibration means 32 imparts vibration to the small component member aligner 10 and a plurality of small component members 6 mounted on or near the small component member aligner 10, for example, a chip capacitor square pillar. The body 6 is moved or fluidized on the small component member alignment tool 10, and the small component member 6 can be transferred into the storage hole 12. Therefore, the vibration means 32 may be any means that exhibits such a function, and examples thereof include a known vibrator, vibrator (vibration generator), and manual vibration. In the small component member alignment apparatus 30 shown in FIG. 7, the vibration means 32 is placed on an alignment tool installation member 33 to be described later. For example, it may be installed adjacent to the alignment tool installation member 33.

  The aligner setting member 33 used in the small component member aligning device 30 shown in FIG. 7 can be mounted with the small component aligner 10 and the flat plate portion 11, that is, the small component aligner 10. The opening 35 to which the small component member aligning tool 10 is attached is formed in a part of one surface so that the closed space 34 is partitioned and formed between the rear surface and the rear surface.

  The member aligning device 30 for small parts according to the present invention is not limited to the above-described embodiment, and various modifications can be made within a range in which the object of the present invention can be achieved. For example, the small component member aligning apparatus may be provided with an inclination means for inclining the housing for causing the small component member to flow on the small component member aligning tool, and a plurality of small components. A plurality of openings may be formed in the housing so that the member alignment tool can be mounted.

  In addition, the alignment tool installation member 33 is a casing. In this invention, the alignment tool installation member is a plate-like body in which a groove is formed in contact with the suction hole of the small component member alignment tool. For example, a plate-like body having grooves formed in a lattice shape at predetermined intervals and a passage connecting the grooves and the suction means may be used.

  The small component member arranging method according to the present invention uses, for example, the small component member aligning tools 10A to 10C or the small component member aligning device 30. Below, the member arrangement method for small parts using the member alignment apparatus 30 for small parts is demonstrated. Specifically, in this small component member arranging method, a plurality of small component members 6 are supplied to the opening surface of the storage hole 12 in the small component member aligning tool 10 which is being vibrated, and the suction means is provided. In this method, the small component member 6 is accommodated in each of the accommodation holes 12 by sucking the inside of the accommodation hole 12 through the suction holes 15 by 31.

  In this small component member arranging method, first, the small component member aligning tool 10 is prepared and arranged so that the inside of the storage hole 12 can be sucked. For example, as shown in FIG. 7, the small component aligner 10 is mounted in the opening 35 of the aligner installation member 33. The suction means 31 connected to the alignment tool installation member 33 is activated to suck the closed space 34, whereby the storage hole 12 communicating with the closed space 34 is sucked through the suction hole 15. On the other hand, a sufficient number of small component members 6 are supplied on the upper surface of the alignment tool installation member 33 and / or on or near the small component member alignment tool 10.

  Next, the vibration means 32 placed on the upper surface of the alignment tool installation member 33 is activated to vibrate the small component member alignment tool 10 and the plurality of small component members 6 together with the alignment tool installation member 33. In this way, when the closed space 34 and the storage hole 12 are sucked and the small component member alignment tool 10 and the plurality of small component members 6 are vibrated, the vibrated small component member 6 is small. It moves or flows in a predetermined direction on the component member alignment tool 10. At this time, if the housing of the small component member aligning device 30 is slightly tilted in the moving direction or flow direction of the small component member 6, the excited small component member 6 moves or flows in the same direction. It can be made more uniform and rapid.

  When the suction of the closed space 34 and the storage hole 12 and the vibration of the small component member aligning tool 10 and the plurality of small component members 6 are continued, for example, as shown in FIG. The small component member 6 moving in a predetermined direction (in the direction of arrow A in FIG. 8) on the base 10 falls into the storage holes 12 one after another from the upstream side in the predetermined direction, and is sucked and stored in each storage hole 12. Is done. At this time, since the suction holes 15 of the small component aligning tool 10 communicate with the respective storage holes 12, the interior of each of the storage holes 12 can be sucked in the same manner. There is no non-uniformity such that the member 6 cannot be sucked and stored. Further, since the storage hole 12 of the small component member aligning tool 10 is sucked by the suction means 31, the small component member 6 dropped into the storage hole 12 is sucked and stored in a desired standing state with high uniformity. The When the small component member 6 finishes moving on the small component member aligning tool 10, the small component member 6 is sucked and stored in the storage hole 12 in a desired standing state.

  The movement of the small component member 6 on the small component member alignment tool 10 may be performed a plurality of times. Further, when the small component member 6 remains on the small component member aligning tool 10, the small component member aligning tool 10 is tilted or inverted together with the aligning tool setting member 33, so that the inside of the storage hole 12. The remaining small component member 6 not sucked and stored in the small component member aligning tool 10 can be removed without causing the small component member 6 sucked and stored to pop out and fall off.

  According to the small component member arranging method according to the present invention, the small component member 6 can be sucked and stored in the desired standing state in each of the storage holes 12 of the small component member aligning tool 10 in this manner. The remaining small component member 6 can be easily removed.

  Further, according to the small component member arranging method according to the present invention, the small component member 6 is manually inserted into the storage hole 12 in the small component member aligner 10 by the vibration means 32 and the suction means 31. And can be stored. Further, since the small component member 6 stored in the storage hole 12 is continuously sucked by the suction means 31, the small component stored in the storage hole 12 is tilted or inverted by tilting or inverting the small component member alignment tool 10. The small component member 6 that is not stored in the storage hole 12 can be easily removed without causing the component member 6 to jump out. Therefore, according to the small component member arranging method according to the present invention, a predetermined number of small component members 6 can be easily aligned in a standing state that can be moved as desired to a holding jig described later. .

  The member arrangement method for small parts according to the present invention is not limited to the above-described embodiments, and various modifications can be made within a range in which the object of the present invention can be achieved. For example, after the small component member 6 is supplied to the upper surface of the aligner installation member 33 or the like, or simultaneously with the supply, the suction means 31 is activated and the closed space 34 is sucked to suck the storage hole 12.

  The electrode forming method for small component members according to the present invention uses the small component member aligning tools 10A to 10C or the small component member aligning device 30. Below, the electrode formation method of the member 6 for small components which uses the member alignment apparatus 30 for small components, for example, the quadratic prism body 6 for chip capacitors, is demonstrated.

Specifically, the electrode forming method for this small component member is:
(1) The square capacitor body 6 for chip capacitors is stored in each storage hole 12 of the member aligner 10 for small parts,
(2) One end portion of the chip capacitor quadrangular column 6 housed in the small component member aligning tool 10 is adhered and held to the first elastic member 3A of the first holding jig 1A.
(3) An electrode 9 is formed on the other end of the chip capacitor quadrangular columnar body 6 adhered and held by the first holding jig 1A.
(4) The other end portion of the chip capacitor quadrangular column 6 that is adhesively held by the first holding jig 1A and that has the electrode 9 formed at the other end thereof is larger in adhesive force than the first elastic member 1A. The square capacitor body 6 for a chip capacitor having an electrode 9 formed on the other end is adhered to the second elastic member 3B of the second holding jig 1B having the second elastic member 3B. Move from the first holding jig 1A to the second holding jig 1B,
(5) In this method, the electrode 9 is formed at one end of the chip capacitor quadrangular columnar body 6 adhered and held by the second holding jig 1B.

  In this small component member electrode forming method, first, (1) a storage step of storing the chip capacitor square column body 6 in each storage hole 12 of the small component member alignment tool 10 is performed. In this storage step, a method of storing the chip capacitor square column body 6 in each storage hole 12 of the small component member alignment tool 10 may be adopted, but the storage hole 12 of the small component member alignment tool 10 may be adopted. Each of the small component members 6 can be easily sucked and stored in a desired standing state, and the remaining small component member 6 can be easily removed. A member arrangement method is preferably selected.

  Next, (2) one end portion (that is, the non-accommodated end portion) of the chip capacitor square column body 6 accommodated in the small component member alignment tool 10 is used as the first elastic member 3A in the first holding jig 1A. An adhesion holding step for holding the adhesion is performed.

  As shown in FIG. 9, the first holding jig 1A used in the first adhesive holding step is a first jig body 2A and a first jig disposed on the first jig body 2A. The elastic member 3A is provided. The first jig body 2A only needs to have a certain degree of strength, and the first elastic member 3A has an adhesive force capable of sticking and holding the chip capacitor square column body 6. For example, it is formed of silicone rubber or the like. As long as the first holding jig 1A has such a configuration, a known holding jig can be used without any particular limitation.

  Specifically, in the adhesion holding step, for example, the first elastic member 3 </ b> A in the first holding jig 1 </ b> A is attached to one end portion of the chip capacitor quadrangular columnar body 6 arranged in the small component member alignment tool 10. By abutting, one end portion of the chip capacitor quadrangular column 6 is adhered and held on the rubber elastic member 3A.

  More specifically, for example, as shown in FIG. 10, in the adhesion holding step, the first elastic member 3 </ b> A is sucked and accommodated in the small component member alignment tool 10 in a standing state. The chip capacitor square column body 6 is brought into contact with one end portion (non-contained end portion) of the body 6 and, if necessary, pressed to hold the chip capacitor square column body 6 in an upright state while holding the chip capacitor square column body 6 in the first state. The elastic member 3A is adhesively held. At this time, the chip capacitor quadrangular columnar body 6 is sucked and accommodated in the small component member aligning tool 10 in a desired standing state, and therefore the chip capacitor quadrangular columnar body 6 protruding from the surface of the small component member aligning tool 10. The protruding length of each chip capacitor is uniform, and each of the chip capacitor quadrangular prisms 6 is uniformly abutted against or pressed against the first elastic member 3A. Therefore, the chip capacitor quadrangular columnar body 6 is adhesively held on the first elastic member 3A in a state where the desired standing state of the small component member aligner 10 is maintained.

  Next, a pulling process is performed in which the first holding jig 1 </ b> A having the first elastic member 3 </ b> A for sticking and holding each of the chip capacitor square columns 6 is relatively separated from the small component member aligning tool 10. When this separation step is carried out, as shown in FIG. 11, each chip capacitor square columnar body 6 is held in a suspended state by the first holding jig 1A. At this time, each chip capacitor quadrangular columnar body 6 adhered and held by the first elastic member 3 </ b> A is in a suspended state in which a desired standing state in the small component aligning tool 10 is maintained. Accordingly, as shown in FIG. 11, each chip capacitor square column 6 is adhesively held by the first holding jig 1 </ b> A with high positional accuracy and high uniformity in the standing state.

  Next, (3) a first electrode forming step is performed in which the electrode 9 is formed on the other end portion (non-adhesive end portion) of the chip capacitor quadrangular columnar body 6 adhered and held by the first holding jig 1A. . In the first electrode forming step, the chip capacitor square pillar body 6 adhered and held by the first holding jig 1A is immersed or brought into contact with the electrode paste bath or the electrode paste layer by a predetermined amount to be used for the chip capacitor. An electrode paste layer is formed on the other end of the rectangular column 6 and dried according to a conventional method. In this manner, as shown in FIG. 12, the electrode 9 can be formed on the other end of the chip capacitor quadrangular column 7 and the electrode 9 formed on the other end of the electrode 9 is formed. A prismatic body 8 can be prepared. Here, the chip capacitor quadrangular columnar body 6 adhered and held by the first holding jig 1A is suspended while maintaining a predetermined standing state, and is arranged in a state where the positional accuracy and the uniformity of the standing state are high. Therefore, the immersion amount or the contact amount of each chip capacitor square column body 6 immersed or brought into contact with the electrode paste bath or electrode paste layer is constant, and as a result, each chip capacitor square column body 6 is formed. The electrode 9 is excellent in positional accuracy and dimensional accuracy.

  Next, (4) the other end portion (non-adhesive electrode forming end portion) of the chip capacitor electrode-forming quadrangular columnar body 8 which is adhesively held by the first holding jig 1A and the electrode 9 is formed at the other end portion. The second elastic member 3B in the second holding jig 1B having the second elastic member 3B having a larger adhesive force than the first elastic member 1A is adhesively held by the second elastic member 3B, thereby forming the chip capacitor electrode 4 A transfer step of transferring the prismatic body 8 from the first holding jig 1A to the second holding jig 1B is performed.

  The second holding jig 1B used in this transfer step is basically the same as the first holding jig 1A, but the second elastic member 3B has a larger adhesive force than the first elastic member 1A. have. Thereby, the chip capacitor electrode-forming quadrangular prism body 8 can be transferred from the first holding jig 1A to the second holding jig 1B.

  Specifically, for example, as shown in FIG. 13, this transfer step is performed by holding the first elastic member 3 </ b> A in the first holding jig 1 </ b> A through the steps (1) to (4). The second elastic member 3B of the second holding jig 1B is brought into contact with the other end portion of the chip capacitor electrode-forming square column body 8 and pressed if necessary, thereby forming the chip capacitor electrode-forming square column. This is a step of transferring the chip capacitor electrode-forming quadrangular columnar body 8 from the first elastic member 3A to the second elastic member 3B while maintaining the suspended state of the body 8. Through this transfer step, the chip capacitor electrode-forming quadrangular columnar body 8 is transferred to the second elastic member 3B. Then, a pulling process is performed in which the first holding jig 1A is relatively pulled away from the second holding jig 1A. When this separation step is performed, as shown in FIG. 14, the chip capacitor electrode-forming quadrangular columnar body 8 is adhesively held by the second holding jig 1 </ b> B. At this time, the chip-capacitor electrode-forming quadrangular columnar body 8 adhered and held by the first elastic member 3A is suspended while maintaining a predetermined standing state, as described above, so that the positional accuracy and the standing state are uniform. The chip capacitor electrode forming quadrangular columnar body 8 transferred to the second elastic member 3B is also adhesively held in an upright state maintaining such a state.

  Next, (5) a second electrode forming step is performed in which the electrode 9 is formed on one end portion (non-adhesive end portion) of the chip capacitor electrode-forming quadrangular columnar body 8 that is adhesively held by the second holding jig 1B. The The second electrode forming step is performed basically in the same manner as the first electrode forming step. In this way, as shown in FIG. 15, the electrode 9 is formed at one end of the chip capacitor electrode forming square column 8 opposite to the other end where the electrode 9 is formed. Here, the chip-capacitor electrode-forming quadrangular columnar bodies 8 that are adhesively held by the second holding jig 1B hold a predetermined standing state, and are arranged in a state where the positional accuracy and the uniformity of the standing state are high. The immersion amount or the contact amount of the chip capacitor electrode-forming square column body 8 immersed or contacted in the electrode paste bath or electrode paste layer is constant, and as a result, at one end of each chip capacitor electrode formation square column body 8 The formed electrode 9 is excellent in positional accuracy and dimensional accuracy.

  Next, a removal step of removing the chip capacitor 5 in which the electrodes 9 are formed on both end portions that are adhesively held by the second elastic member 3B is performed. In the removing step, for example, the chip capacitor 5 can be easily detached by a method of scanning the second elastic member 3B with a squeegee or the like.

  In this manner, as shown in FIG. 16, it is possible to manufacture the chip capacitor 5 in which the electrodes 9 are formed on both ends of the chip capacitor square column body 6. In addition, according to the electrode forming method for a small component member according to the present invention, a plurality of chip capacitor quadrangular column bodies 6 are maintained in a desired standing state using the small component member alignment tool 10 according to the present invention. It can be transferred to the first holding jig 1A as it is, and the chip-capacitor electrode-formed square column body 8 can be transferred from the first holding jig 1A to the second holding jig 1B while maintaining a desired standing state. Therefore, the plurality of chip capacitor square columns 6 and the chip capacitor electrode-formed square columns 8 transferred to the holding jigs 1A and 1B have a high positional accuracy and high uniformity of the standing state. As a result, the electrodes 9 having excellent positional accuracy and dimensional accuracy are formed at a time on each of the plurality of chip capacitor square columns 6 and the chip capacitor electrode forming square columns 8. It can be.
