Description

  The present invention relates to a holding jig and a set of holding jigs. More specifically, even if the size of the holding jig is increased, the elastic member is hardly detached from the jig main body and exhibits high durability without greatly sacrificing handling. The present invention relates to a holding jig and a set of holding jigs.

  2. Description of the Related Art Conventionally, when manufacturing small parts such as a chip capacitor, a holding jig capable of sticking and holding a member for small parts capable of manufacturing the small parts on the surface thereof has been used. Such a holding jig is usually provided with an elastic member having an adhesive surface and a jig body that supports the elastic member. For example, Patent Document 1 discloses "a perspective view showing an electronic component chip holder 21 according to an embodiment of the present invention. The holder 21 includes a plate-like main body 22 made of a material such as metal or resin. The adhesive film 23 is formed on the main body 22, thereby providing the adhesive surface 24 on the surface of the adhesive film 23 ”(see column 0029 and FIG. 1).

  In such a holding jig, the adhesion of the object to be adhered and the removal of the object to be adhered which have been adhered are repeated. When the adherend is detached from the elastic member, stress is generated in the elastic member in the direction of pulling away from the jig body. Then, due to repeated detachment of the adherend, the adhesion between the jig main body and the elastic member gradually decreases, and the elastic member provided on the jig main body may peel from the jig main body.

  In particular, in order to respond to demands for further downsizing of the adherend and improvement of production efficiency, etc., the number of adherends held by the holding jig tends to increase. The stress is further increased, and the elastic member is more easily separated from the jig body.

  Further, the size of the holding jig is appropriately adjusted according to the size, number, productivity, and the like of the objects to be adhered and held, and in recent years, the holding jig may be enlarged. Then, since the jig main body of the holding jig is usually formed of metal or the like, the mass of the holding jig itself is increased, the handling property is inferior, and the elastic member is more easily separated from the jig main body.

  As described above, when the elastic member of the holding jig is peeled off from the jig main body, not only the object to be adhered cannot be held and detached as desired, but also the quality of the manufactured product may be deteriorated. The holding jig is required to prevent the elastic member from being easily detached from the jig body.

Japanese Patent No. 2682250

  The present invention provides a holding jig and a set of holding jigs that exhibit high durability in which the elastic member is not easily detached from the jig body without greatly sacrificing handling even if the size is increased. Objective.

As means for solving the problems,
Claim 1 is a jig main body having an elastic member capable of sticking and holding an object to be adhered on the surface, and a plurality of insertion portions in which the elastic member is disposed on the surface of the elastic member and the elastic member can be inserted. The elastic member has a plurality of legs inserted into the insertion part, and the legs arranged in the outermost row of the legs are flush with the end surface of the elastic member. A holding jig characterized by having an outermost surface ;
Claim 2 is the holding jig according to claim 1, wherein the insertion portion penetrates in the thickness direction of the jig body.
According to a third aspect of the present invention, there is provided a holding jig having a holding jig having an elastic member capable of adhering and holding an adherend to the surface and a jig body, and at least one of the holding jigs. One of the holding jigs according to claim 1 or 2 is a set of holding jigs.

  Since the holding jig according to the present invention has the elastic member formed on the surface of the jig main body so that at least a part of the elastic member is inserted into the insertion portion formed on the jig main body, Even if the size of the holding jig is increased, it is possible to reduce the weight of the jig body by avoiding a significant increase in its mass, and it is possible to greatly enhance the adhesion between the jig body and the elastic member. . Therefore, according to the present invention, it is possible to provide a holding jig that exhibits high durability in which the elastic member is difficult to be detached from the jig body without greatly sacrificing handling even when the size is increased.

  The set of holding jigs according to the present invention includes the holding jig according to the present invention. Therefore, according to the present invention, it is possible to provide a set of holding jigs that exhibit high durability in which the elastic member is not easily detached from the jig body without greatly sacrificing handling even when the size is increased. .

  A holding jig as an embodiment of the holding jig according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the holding jig 1 includes an elastic member 21 capable of sticking and holding an adherend on the surface, and a plurality of insertion portions 15 (FIG. 1 ( a jig body 11 having a reference (b)). The holding jig 1 can hold an adherend on the adhesive surface of the elastic member 21 with the adhesive force of the elastic member 21.

  Examples of the object to be adhered and held by the holding jig according to the present invention include small component members capable of manufacturing small components, such as small instrument members, small machine element members, and small electronic component members. . In addition, since the manufacture of small parts includes a process of transporting small parts, the adherend includes small parts themselves, for example, small instruments, small machine elements, and small electronic parts. Therefore, in the present invention, it is not necessary to clearly distinguish the small component from the small component member. Among these adherends, examples of the adherend suitable for the holding jig according to the present invention to stick and hold include small electronic components and / or members for small electronic components. As the small electronic component and the small electronic component member, for example, a capacitor chip (sometimes referred to as a chip capacitor), an inductor chip, a resistor chip, an FPC, a wafer, or a finished product or an unfinished product, or these Examples include a manufacturable member.

The jig body 11 holds or supports the elastic member 21. As shown in FIGS. 1 and 2, the jig body 11 is formed into a disk-shaped body having a square shape. The jig main body 11 is drilled in a lattice state in which insertion portions 15 penetrating in the thickness direction of the jig main body 11 are arranged at substantially equal intervals in the vertical direction and the horizontal direction. The insertion portion 15 is formed so that a cross section perpendicular to the axial direction is a square. The number of perforations and the size of the cross section of the insertion portion 15 are adjusted so that the jig body 11 can be reduced in weight and can have improved adhesion to the elastic member 21 described later. For example, as an example, the charging sections 15 having a cross-sectional area of 25 mm ² may be arranged in a grid pattern in 10 rows × 10 rows.

  The jig body 11 has a smooth surface and can be in various forms based on various design changes as long as the elastic member 21 can be held or supported. The jig body 11 is adjusted to an appropriate size and thickness in accordance with the production efficiency, the size and number of objects to be adhered, and the like. If the thickness of the jig main body 11 is too large, the mass increases and the handleability decreases, so it is sufficient that the jig main body 11 has a thickness that can support at least the elastic member 10. The thickness of the jig body 11 is usually made uniform.

  The material forming the jig body 11 may be any material that can hold or support the elastic member 21, for example, a metal plate such as stainless steel and aluminum, a metal foil, a resin film, a resin plate, ceramics, or the like. Can be mentioned.

  The elastic member 21 is designed so that a large number of objects to be adhered can be held by adhesion, and is formed on the surface of the jig body 11. As shown in FIG. 1, the elastic member 21 is formed in a sheet shape, and a plurality of leg portions 25 to be inserted into the insertion portion 15 of the jig body 11 are formed on one surface thereof. The leg portion 25 is inserted into the insertion portion 15 to reinforce the adhesion between the jig body 11 and the elastic member 21. Therefore, the leg portion 25 has the same arrangement as the insertion portion 15 and has the same length in the axial direction as the shape of the cross section of the insertion portion 15 and the thickness of the jig body 11. It extends substantially perpendicularly from one surface. As shown in FIG. 1, the outermost surfaces 29 of the leg portions 25 arranged in the outermost row of the leg portions 21 are flush with the end surfaces 28 of the elastic member 21.

The elastic member 21, particularly the adhesive surface thereof, is formed of, for example, a cured product of an adhesive material described later, and has an adhesive force capable of sticking and holding the adherend, for example, an adhesive force of 1 to 50 g / mm ^2. ing. The adhesive force of the elastic member 21 can be measured according to the “Shin-Etsu Polymer Method” described in JP-A-2007-16597. The elastic member 21 should have a smooth adhesive surface for sticking and holding an object to be adhered. Specifically, for example, the ten-point average roughness Rz (JIS B 0601-1994) of the adhesive surface is 5 μm or less. Has been adjusted. The ten-point average roughness Rz is measured under conditions such as a cutoff of 0.8 mm and a measurement length of 2.4 mm. The elastic member 21 has a surface hardness (JIS K6253 [durometer E]) of 5 to 60. The elastic member 21 preferably has a uniform thickness, and is adjusted to a thickness of 1 to 10 mm, for example.

  As a material for forming the elastic member 21, any adhesive material can be used as long as it can provide the elastic member 21 with an adhesive force in the above range. Examples of such an adhesive material include fluorine resin or fluorine rubber, fluorine composition containing fluorine resin or fluorine rubber, silicone resin or silicone rubber, silicone composition containing silicone resin or silicone rubber, and the like. Products, urethane elastomers, natural rubber, and various elastomers such as styrene-butadiene copolymer elastomer. Among these, “silicone raw rubber (a), crosslinking component (b), adhesive component (c), catalyst (d), and silica-based filler (e) described in JP2007-307529A. “Adhesive Silicone Rubber Composition”, “Silicone Raw Rubber (a), Adhesive Component (c), Silica-Based Filler (e), and Organic Peroxide (f)” described in JP-A-2007-307529 And an adhesive silicone rubber composition containing

  As shown in FIG. 1, the holding jig 1 includes a jig body 11 and an elastic member 21, and the entire leg portion 25 of the elastic member 21 is loaded into a loading portion 15 formed in the jig body 11. As described above, the elastic member 21 is formed on one surface of the jig body 11. That is, the elastic member 21 is formed on one surface of the jig body 11 so that the side surface of the leg portion 25 of the elastic member 21 is in contact with the inner surface of the insertion portion 15 of the jig body 11. The contact surface between the jig body 11 and the elastic member 21 may be adhered and held by the adhesive force of the elastic member 21, or may be tightly fixed with an adhesive or the like. These contact surfaces are preferably bonded and fixed with an adhesive in that high durability of the holding jig 1 can be realized.

  As described above, the holding jig 1 in which the insertion portion 15 is formed in the jig main body 11 and the leg portion 25 of the elastic member 21 is inserted into the insertion portion 15 is elastic to the jig main body 11. The adhesiveness with the member 21 is greatly enhanced, and the elastic member 21 is peeled off from the jig main body 11 over a long period of time and / or over many times of adhesion holding and desorption of the adherend. Can be prevented.

  Further, the holding jig 1 includes an elastic member 21 in which the outermost surface 29 of the leg portion 25 arranged in the outermost row of the elastic members 21 is formed flush with each end surface 28 of the elastic member 21. . Then, peeling of the end surface of the elastic member 21 has been a big problem in the past. However, when the holding jig 1 includes such an elastic member 21, the end surface 28 of the elastic member 21 is the outermost portion of the leg portion 21. It continues to the outer side surface 29 and extends to the insertion portion 15 of the jig body 11 without interruption on the surface of the jig body 11. Therefore, the end face 28 of the elastic member 21 is not peeled off from the surface of the jig body 11, and the durability of the holding jig 1 can be further improved.

  Furthermore, since the mass of the jig body 11 is greatly reduced by drilling the insertion portion 15, even if the holding jig 1 is enlarged, the handling property due to the increase in mass is greatly sacrificed. In addition, the elastic member 21 can be effectively prevented from peeling off.

  Therefore, even if the holding jig 1 is enlarged, the elastic member 21 is not easily detached from the jig main body 11 without greatly sacrificing handleability, and exhibits high durability.

  In addition to such effects, the holding jig 1 also has the following effects. For example, since the holding jig generally needs to hold the object to be adhered to a predetermined position of the elastic member, the elastic member is formed at a predetermined position of the jig body. The elastic member may be displaced from a predetermined position of the jig main body due to use or the like, and as a result, the adherend may not be adhered and held at the predetermined position of the elastic member. In particular, in recent years, objects to be adhered have been further miniaturized, and such problems have become prominent. However, in the holding jig 1, since the leg portion 25 of the elastic member 21 is inserted into the insertion portion 15, the displacement of the elastic member 21 in the horizontal direction is effectively restricted by the leg portion 25. Therefore, the holding jig 1 can prevent the displacement of the elastic member 21 and can adhere and hold the adherend to a predetermined position of the elastic member. Can be used to.

  Further, as shown in FIG. 1B, the holding jig 1 has an end surface of the leg portion 25 of the elastic member 21 exposed on the surface opposite to the surface on which the elastic member 21 is formed. Since the end surface of the leg portion 25 is an adhesive surface, when the holding jig 1 is placed, the holding jig 1 is fixed on the end surface of the leg portion 25. Further, it is not necessary to use a suction device and a magnetic device that have been conventionally used to fix the holding jig 1 at a predetermined position. In addition, when the adhesiveness of the end surface of the leg part 25 is unnecessary, the said end surface can be made non-adhesive by the non-adhesion process, for example, an ultraviolet irradiation process, a roughening process, etc.

  The holding jig which is another Example in the holding jig which concerns on this invention is demonstrated with reference to drawings. FIG. 3 is a cross-sectional view of the holding jig corresponding to FIG. As shown in FIG. 3, the holding jig 2 includes an elastic member 22 capable of sticking and holding an adherend on the surface, and a jig having a plurality of insertion portions 16 into which the elastic member 22 can be inserted. And a main body 12. The holding jig 2 can hold an adherend on the adhesive surface of the elastic member 22 with the adhesive force of the elastic member 22.

  The holding jig 21 is other than the insertion portion 16 not penetrating in the thickness direction of the jig main body 12 and the leg portion 26 of the elastic member 21 not being exposed on the back surface of the jig main body 11. Is basically the same as the holding jig 1. The depth of the insertion portion 16 does not have to penetrate the jig body 12 and is adjusted to an appropriate depth in consideration of, for example, the adhesion between the jig body 12 and the elastic member 22.

  The holding jig 2 includes a jig main body 12 and an elastic member 22, and an elastic member so that the entire leg portion 26 of the elastic member 22 is inserted into the insertion portion 16 formed in the jig main body 12. 22 is formed on one surface of the jig body 12. Therefore, like the holding jig 1, the holding jig 2 exhibits high durability without causing the elastic member 22 to be detached from the jig main body 12 without greatly sacrificing handling even when the holding jig 2 is enlarged. In addition, the holding jig 2 can prevent the elastic member 22 from being displaced, and can be used for sticking and holding and detaching the adherend many times.

  Unlike the holding jig 1, the holding jig 2 is mounted on the surface opposite to the surface on which the elastic member 22 is formed because the end surface of the leg portion 26 of the elastic member 22 is not exposed. The holding jig 2 is not adhered to the placement surface when placed, and the handleability when not in use is excellent.

  The holding jig which is another Example in the holding jig which concerns on this invention is demonstrated with reference to drawings. As shown in FIG. 4A, the holding jig 3 includes an elastic member 23 capable of sticking and holding an object to be adhered to the surface, and a plurality of insertion portions 17 into which the elastic member 23 can be inserted. The jig body 13 is provided. The holding jig 3 can hold an adherend on the adhesive surface of the elastic member 23 with the adhesive force of the elastic member 23.

  The holding jig 3 is formed with a loading portion 17 (see FIG. 4B) penetrating in the thickness direction of the jig body 13 and extending along one side of the jig body 13. And the holding jig 17 is basically the same as the holding jig 1 except that the legs 27 shorter than the depth of the insertion portion 17 are formed on the elastic member 23 in the same arrangement as the insertion portion 17. Is formed. That is, the insertion portion 17 is formed in a through groove that extends along one side of the jig body 13. A plurality of the loading portions 17 are arranged at a predetermined interval in a direction perpendicular to the extending direction. The leg portions 27 of the elastic member 23 extend substantially perpendicularly from one surface of the elastic member 23 so as to be inserted into the insertion portion 17 and are arranged in the same manner as the insertion portion 17. Is formed. And this leg part 27 is shorter than the depth of the insertion part 17, and when it is set as the holding jig 3, it is inserted only to the middle of the depth direction of the insertion part 17 (Fig.4 (a)). reference.).

  The holding jig 3 includes a jig body 13 and an elastic member 23, and the entire leg portion 27 of the elastic member 23 is inserted halfway through the insertion portion 17 formed on the jig body 13. An elastic member 23 is formed on one surface of the jig body 13. Therefore, like the holding jig 1, the holding jig 3 exhibits high durability because the elastic member 23 is not easily detached from the jig main body 13 without greatly sacrificing handling even when the holding jig 3 is enlarged. In addition, the holding jig 3 can prevent the elastic member 23 from being displaced, and can be used for sticking and releasing the adherend for many times.

  Unlike the holding jig 1, the holding jig 3 is mounted on the surface opposite to the surface on which the elastic member 23 is formed because the end surface of the leg portion 27 of the elastic member 23 is not exposed. It is not sticky to the mounting surface when placed, and is excellent in handleability when not in use.

  The holding jig according to the present invention is manufactured as follows, for example. The jig body having the insertion portion can be manufactured by using, for example, the above-described material, for example, by vacuum forming, injection molding, mold forming, or the like. In addition, the jig body having the insertion portion can be manufactured by forming a desired insertion portion by cutting or the like after forming the disc body using the material. A holding jig provided with an elastic member is manufactured by applying an adhesive to the jig body produced in this way as desired, and injecting and molding the material into a mold containing the jig body. Can be done. The holding jig provided with the elastic member is coated with an adhesive as desired so that the leg portion of the elastic member formed into the desired shape using the material is inserted into the insertion portion. It can be manufactured by placing on the jig body and curing the adhesive if desired.

  The holding jig 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, in the holding jigs 1 and 2, the loading portions 15 and 16 are respectively provided with leg portions 25 and 26. In the present invention, the loading portion has a leg portion at a part thereof. It only has to be charged. For example, like the holding jig 3 shown in FIG. 4A, a leg portion 27 shorter than the depth of the insertion portion 17 is formed on the elastic member 23, and the leg portion 27 is formed on a part of the insertion portion 17. May be charged.

  Further, in the holding jigs 1 and 2, the charging portions 15 and 16 are both arranged in the vertical and horizontal directions at substantially equal intervals, and in the holding jig 3, the charging portions 17 are arranged in almost equal intervals. However, in the present invention, the charging portions may not be arranged as described above, and may be arranged in a concentric shape, a radial shape, or the like, for example.

  Further, in the holding jigs 1 to 3, the charging portions 15 to 17 are all rectangular in the cross-sectional shape perpendicular to the axial direction. In this invention, the shape of the cross section in the charging portion is arbitrary. It may be formed into a shape. Examples of such a shape include a polygon such as a quadrangle, a pentagon, and a hexagon, a circle, an ellipse, an indeterminate shape, or a combination of these.

It is adjusted to have adhesive strength. Since the elastic member 21A and the elastic member 21B have such an adhesive force relationship, the object to be adhered can be transferred from the elastic member 21A of the holding jig 1A to the elastic member 21B of the holding jig 1B. The difference in adhesive force between the elastic member 21A and the elastic member 21B according to the “Shin-Etsu Polymer Method” is 15 to 43 g in that the adherend can be smoothly transferred from the elastic member 21A to the elastic member 21B without dropping off. / Mm ² is preferred.

  The set of holding jigs according to the present invention is suitably used for holding an adhesive for a small electronic component member that needs to be coated with a conductive paste in at least two places. As an example of a small electronic component member that needs to be coated with a conductive paste in at least two places, a chip capacitor will be described as an example. A chip capacitor is formed by forming electrodes on both ends in the axial direction of a prismatic body or a cylindrical body. Therefore, in such a jig body, the chip capacitor manufacturing member is adhered and held on the surface, and after forming one electrode on the lower end surface of the chip capacitor manufacturing member, the chip capacitor manufacturing member is It is necessary to detach from the holding jig and then hold the end face formed with the electrodes in close contact with the surface of the holding jig again.
