Description

  The present invention relates to a stirring vessel that revolves around a revolution axis while revolving around the revolution axis, a stirring deaerator equipped with the stirring vessel, and a seal manufactured with the stirring vessel It relates to resin materials.

  Silicone-based resins are becoming mainstream as sealing materials used in recent LED packages. Silicone resins have a lower viscosity than epoxy resin sealing materials. Moreover, it is difficult to obtain a uniform kneaded state due to the large specific gravity difference between the sealing material and the phosphor and the low viscosity of the sealing material described above.

Japanese Patent Laid-Open No. 10-43568 JP 2001-353405 A JP 2011-218309 A

  When kneading phosphors and resins, there has been a conventional method of stirring the material in a container with a spatula etc., but due to individual differences, chromaticity variation among LED package device characteristics It was a problem if there was a large. In addition, a stirrer using a stirrer or a propeller has been used. However, since the apparatus and the phosphor material are in contact with each other, damage to the composition of the phosphor material has been a problem.

  Recently, as shown in, for example, Patent Document 1, a stirring and defoaming device capable of kneading a material by the rotation of the rotation and revolution method and the centrifugal force due to the revolution has been used. Since it is non-contact, it can be kneaded without damage to the phosphor material.

  As described above, the rotation and revolution type stirrer stirs the material using the centrifugal force generated by the rotation and revolution. However, depending on the materials to be combined, uniform kneading may not be possible. The reason is that in a rotating and rotating stirrer, a portion corresponding to the center of the rotation axis of rotation, particularly a portion having a weak stirring force exists near the center of the bottom surface of the container, and deposits are generated. The amount of the deposit varies depending on the viscosity of the material put in the container for storing the material when stirring, but the amount of deposit tends to increase because the viscosity is low particularly when a silicone resin is used.

  Specifically, when the silicone resin and the phosphor are kneaded with a rotation and revolution type stirrer, a part of the phosphor is deposited on the bottom of the container during the stirring, and the phosphor concentration in the part increases, and the kneading is performed. Later, when transferring to a syringe or the like, a portion where the phosphor is dark is also mixed. In order to make the device characteristics of the LED package uniform, it is very important to stabilize the chromaticity by aligning the concentration ratio of the phosphor and the silicone resin, but if there is a portion where the phosphor is dark, the chromaticity There is a risk of greatly affecting.

  Thus, for example, Patent Documents 2 and 3 show examples in which the central portion of the cylindrical container is formed in a convex shape protruding into the container so that the material can move easily. In these examples, stagnation at the center of the container is reduced, and a more uniform mixing state is obtained. However, considering the stirring principle, there is a possibility that a region where the flow of the material is weakened is generated at a part of the bottom of the container, and uneven stirring of the material may occur in the region.

  The present invention provides a stirring container used in a stirring and defoaming apparatus capable of enhancing stirring performance in the field of a rotation and revolution type stirring and defoaming apparatus, and a sealing resin material manufactured using the stirring container. Objective.

  The present invention is a stirring vessel for stirring a material held inside and held by a container holder that revolves around a revolution axis while revolving around a revolution axis, the material being contained therein And a convex portion extending in the radial direction except for the central portion is provided on the bottom surface of the container.

  In the stirring container according to the present invention, since the convex portion is formed, the flow generated when the convex portion rotates and the regular convection due to rotation and revolution can be dispersed by the flow. Therefore, when the stirring container according to the present invention is used in a stirring and defoaming apparatus of the rotation and revolution type, the amount of powder material deposited near the center of the container bottom can be reduced.

  In the stirring container according to the present invention, the convex portion has a polygonal cross section (for example, a triangular cross section or a quadrangular cross section), and a plurality of radial shapes are formed on the bottom surface of the container.

  In the stirring container according to the present invention, the container includes a stirring blade made of a ferromagnetic material having a convex portion. Further, the container holder includes a magnet for attracting and holding the container.

  According to the above configuration, the stirring blade made of a ferromagnetic material is installed on the bottom of the container, and the stirring blade can be firmly fixed by a magnetic force by being attached to a container holder equipped with a magnet. Any type of container can be used. Therefore, when the stirring container according to the present invention is used in a stirring and defoaming apparatus of the rotation and revolution type, the amount of powder material deposited near the center of the container bottom can be reduced.

  Moreover, since the sealing resin material manufactured with the stirring container according to the present invention can reduce the amount of the powder material deposited near the center of the container bottom, the member resin in which the powder material and the liquid material are uniformly mixed The material can be manufactured.

  According to the present invention, since the convex portion extending in the radial direction is formed except for the central portion of the bottom surface of the container, the flow generated when the convex portion rotates, and the regular convection due to rotation and revolution by the flow is performed. By dispersing, it is possible to reduce the amount of powder material deposited near the center of the container bottom.

That is, all the configurations described in the following embodiments are not necessarily essential to the present invention. In addition, as described below, the present invention includes a combination of a stirring and degassing apparatus 11, a stirring container, a material, and a stirring method.

  First, the stirring deaerator 11 will be described.

  FIG. 1 is a perspective view for conceptually explaining an agitation / deaeration device 11 according to an embodiment of the present invention. The stirring and defoaming device 11 includes a revolution rotation shaft L1 and a rotation rotation shaft L2. The rotation axis L2 is configured to cross at an angle of 45 ° with respect to the revolution axis L1 extending in the vertical direction. However, the crossing angle between the revolution rotation axis L1 and the rotation rotation axis L2 is not limited to 45 °, and is preferably set in a timely manner according to the properties of the material M. The rotation directions of the revolution rotation axis L1 and the rotation rotation axis L2 rotate in opposite directions. That is, when the revolution rotation axis L1 rotates clockwise when viewed from above, the rotation rotation axis L2 rotates counterclockwise when viewed from above. The extending directions of one end of the revolution rotation axis L1 and one end of the rotation rotation axis L2 are the same.

  The rotating body 30 is rotated by the power of a driving motor (not shown) around a rotating shaft 31 having the revolution rotating shaft L1 as an axis. On the outer peripheral edge of the rotating body 31, the rotation axis L <b> 2 is held with an inclination of 45 ° with respect to the rotating body 30. The rotation shaft L2 rotates when power of a drive motor (not shown) is transmitted through a belt, a pulley, a bearing, and the like. The rotation axis L2 rotates the holder receiver 15. The holder receiving portion 15 holds the container holder 13, and the container holder 13 rotates while holding the container 14 charged with the material M.

  Note that the container holder 13 equipped with the container 14 is referred to as a stirring container 12. The stirring deaerator 11 can stir the material M (a different material such as a liquid material or a powder material) in the container 14 by these revolutions and convection generated by the rotation.

  Examples of the stirring and defoaming device used as the stirring and defoaming device 11 include V-mini300 manufactured by EME, ARV-310 manufactured by Shinky, and the like.

Next, the stirring vessel 12 will be described. FIGS. 2A to 2C are diagrams for explaining the stirring vessel 12. In particular, FIG. 2A shows a perspective view, FIG. 2B shows a top view, and FIG. It is sectional drawing which follows line AA 'shown.

  The stirring container 12 is constituted by a cylindrical container holder 13 and a container 14 each having an upper opening, and each of them is rotated concentrically. On the inner side of the container holder 13, ring-shaped portions 13 a and 13 b whose inner peripheral surface abuts on the outer peripheral surface of the container 14 are formed at a predetermined interval. The container 14 is firmly held by the container holder 13 by the ring-shaped parts 13a and 13b. A convex portion 21 having a triangular cross section protruding from the bottom surface is formed on the bottom surface of the container 14 so as to extend in the radial direction except for the central portion of the bottom surface.

  The arrangement of the convex portions 21 shown in the figure is an example, but a total of four convex portions 21 are arranged radially every 90 ° around the center of the bottom surface of the container 14 toward the edge of the bottom surface of the container 14 except for the central portion. Has been. In addition, the arrangement of the convex portion 21 at the bottom of the container 14 may be 120 °, 60 °, 30 °, etc. in addition to 90 °, and the cross-sectional shape of the convex portion 21 is not limited to a triangle, but a quadrilateral or other polygons. Shape may be sufficient. That is, it is preferable to form the convex portions 21 so as to surround the vicinity of the center at positions other than the vicinity of the center of the bottom surface of the container 14.

  By forming the convex portion 21, when the stirring container 12 (both the container holder 13 and the container 14) rotates, a liquid flow is generated upward and laterally to perform stirring. That is, the flow generated when the convex portion 21 rotates, and the regular convection due to rotation and revolution can be dispersed by the flow. Thereby, compared with the normal stirring container in which the convex part 21 of the stirring container 12 is not formed, the powder material contained in the material M deposited near the center of the bottom of the container 14 in the stirring and defoaming device 11 of the rotation and revolution method. The amount of deposition can be reduced.

  As described above, the shape of the convex portion 21 formed on the bottom of the stirring vessel 12 is not limited to the illustrated shape, and the convex portion 21 is disposed on the portion of the stirring vessel 12 other than the bottom center of the vessel 14. Thus, it is possible to reduce the deposition amount of the powder material contained in the material M deposited near the bottom center of the container 12 in the rotation and revolution type stirring and defoaming device 11.

  Examples of the liquid material contained in the material M include epoxy resins, acrylic resins, silicone resins, and the like.

  Examples of the powder material included in the material M include a yellow phosphor, a red phosphor, and a green phosphor.

  3A to 3C are views showing other examples of the stirring container, in particular, FIG. 3A shows a perspective view, FIG. 3B shows a top view, and FIG. 3C shows a line BB ′ shown in FIG. 3B. It is sectional drawing which follows.

As shown in FIGS. 3A to 3C, the stirring container 12 is made of a container holder 13 in which a magnet 41 is partially incorporated, a container 14 containing the material M, and a ferromagnetic material attached to the bottom surface of the container 14. And a stirring blade jig 42. A stirrer blade jig 42 made of a ferromagnetic material mounted on the bottom surface of the container 14 by installing a stirrer blade jig 42 made of a ferromagnetic material on the bottom surface of the container 14 and a magnet 41 on the bottom surface of the container holder 13. Since 42 is firmly attracted (magnetically attached) by the magnet 41 through the bottom surface of the container 14, the container 14 can be securely fixed to the container holder 13 together with the stirring blade jig 42. In this case, since the stirring blade jig 42 is formed of a ferromagnetic material, the stirring blade jig 42 is firmly adsorbed (magnetically attached) to the magnet 41, so that even if the container holder 13 and the container 14 rotate at high speed, the container 14 There is no worry that it will come off from the container holder 13.

  The magnet 41 is made of a ferromagnetic material formed in a ring shape or a disk shape, and examples of the ferromagnetic material include iron, cobalt, nickel, and the like. The stirring blade jig 42 may be covered with Teflon (registered trademark) or the like in order to increase chemical resistance. The stirring blade jig 42 has a disk-like shape that is in close contact with the bottom surface of the container 14, and the material M (liquid material and powder material) is disposed between the bottom surface of the stirring blade jig 42 and the bottom surface of the container 14. Etc.), the lower surface (bottom surface) of the stirring blade jig 42 and the bottom surface of the container 14 are preferably flat. Thereby, the lower surface (bottom surface) of the stirring blade jig 42 and the bottom surface of the container 14 are in close contact with each other by the attractive force (magnetization force) of the magnet 41, and the material M does not enter.

  Also. On the upper surface of the stirring blade jig 42, except for the central portion, convex portions 21 having a triangular cross section are formed radially so as to extend in the radial direction. The shape of the convex portion 21 shown in the figure is an example, and may be a polygonal shape such as a rectangular cross section other than a triangular cross section. In addition, the arrangement of the convex portions 21 of the stirring jig 42 attached to the bottom of the container 12 may be 120 °, 60 °, 30 °, etc. in addition to 90 °. In short, it is preferable to form the convex portions 21 so as to surround the vicinity of the center at positions other than the vicinity of the center of the bottom surface of the container 14.

  When the stirring container 12 (both the container holder 13 and the container 14) rotates, the flow generated when the convex portion 21 rotates, and the regular convection due to rotation and revolution can be dispersed by the flow, and the upward and lateral directions The liquid flow is generated and stirring is performed. As a result, the powder material contained in the material M is accumulated at the bottom center of the container 14 at the bottom of the stirring container 12 as in the case of the normal container 14 where the convex portion 21 of the stirring container 12 is not formed. It is possible to prevent and reduce the amount of powder material contained in the material M deposited near the center of the bottom of the container 14 in the rotation and revolution type stirring and defoaming device 11. Thereby, the powder material which is the material M, a liquid material, etc. can be mixed uniformly.

  As described above, the shape of the convex portion 21 formed on the stirring blade jig 42 attached to the bottom of the container 14 is not limited to the illustrated shape, and the convex portion is formed on the portion of the stirring container 12 except for the bottom center of the container 14. 21 is arranged to prevent the powder material contained in the material M from accumulating at the bottom center of the container 14 at the bottom of the stirring container 12, and the bottom surface of the container 14 in the stirring and defoaming device 11 of the rotation and revolution method is prevented. It is possible to reduce the deposition amount of the powder material included in the material M deposited near the center.

  Examples of the liquid material contained in the material M include epoxy resins, acrylic resins, silicone resins, and the like.

  Examples of the powder material included in the material M include a yellow phosphor, a red phosphor, and a green phosphor.

  As a container, the disposable cup (model number: V-100) made from ASONE which is a commercial item, etc. are mentioned, for example. The bottom shape is preferably flat with no irregularities.

  The material M applicable to the embodiment of the present invention only needs to behave as a fluid, and the composition and use thereof are not particularly limited. As the material M, a material including only a liquid component (resin or the like), a material including a granular component (powder component) in addition to a fluid component, or the like can be applied. In addition to mixed materials including LED phosphors, for example, adhesives, sealants, liquid crystal materials, solder pastes, curable resin materials used for shaping, dental impression materials, dental cements Various materials such as a filling agent (a filling agent) and a liquid medicine can be applied.

  Next, a method for stirring and defoaming the material M according to the embodiment of the present invention will be described with reference to FIG. Here, FIG. 4 is a flowchart for explaining the stirring defoaming method.
