Description

  The present invention relates to a rotation / revolution type agitation / defoaming device in which a material to be kneaded is mixed using a combined centrifugal force by revolving and rotating the material to be kneaded.

  Conventionally, a rotation / revolution type stirring and defoaming device using a composite centrifugal force by revolving and rotating the material to be kneaded is known, for example, kneading to be difficult to knead in a normal stirring operation such as a high viscosity substance. Since products are also kneaded reliably in a short time and have a defoaming action, they are used in various fields.

  In particular, recently, this kind of agitation / defoaming apparatus is used in, for example, a solder paste used for soldering to connect a semiconductor device to a printed wiring part in manufacturing an electric circuit device using a printed circuit board, and various manufacturing processes. It is used for kneading and defoaming a material to be kneaded in which a highly viscous kneading agent such as an epoxy resin adhesive and a coating agent used in No. 1 is filled in a syringe.

  However, since the material to be kneaded has a high viscosity, only a specific part is kneaded in a rotation / revolution type stirring / defoaming apparatus in which a conventional material to be kneaded is arranged along the rotation axis. I couldn't.

  Therefore, the material to be kneaded is placed on the revolution rotator that rotates in a horizontal plane around the revolution axis (reference axis), and the rotation rotator that rotates around the rotation axis provided at the radial position from the rotation center of the revolution rotator. By placing the vertically long kneaded material storage container stored at an angle with respect to the rotation axis, in addition to the double centrifugal force due to rotation and revolution, precession (rotates in a swinging manner) causes vertical movement. In addition, there has been proposed a rotation / revolution type agitation / defoaming device in which the whole is kneaded by a moving motion due to a large kneading action, and is disclosed, for example, in JP-A-6-343913.

  The rotation / revolution type agitation / defoaming device presented in JP-A-6-343913 is rotated by, for example, an electric motor 5 in a horizontal plane around a revolution axis (reference axis) A as shown in FIG. The center of a revolving rotating body 1 and a vertically long kneaded object storage container 9 in which a material to be kneaded is stored in a rotating rotating body 2 that rotates about a rotation axis B provided at a radial position from the rotation center of the revolving rotating body 1. The axis C is disposed obliquely with respect to the rotation axis B, and the center axis C of the kneaded material storage container 9 that stores the material to be kneaded around the rotation axis B is arranged coaxially. Compared to a revolving type stirring and defoaming device (not shown), it has an advantage that a large stirring force and a defoaming effect can be exhibited by the kneading action by the vertical movement by precession.

  However, in the conventional rotation / revolution type stirring / defoaming device presented in this publication, the material storage container 9 is supported on the top of a columnar support (shaft) 93.

  By the way, it is generally known that it is necessary to rotate the revolution rotator at a high speed exceeding 2,000 rpm, for example, when targeting a highly viscous material to be kneaded in a syringe, for example, In the attachment means to the rotating rotating body 2 that supports the lower part of the kneaded material storage container 9 as shown in the above publication by a support body (shaft) 93 having a columnar shape, the limit is about 500 to 600 rpm from the structure. However, there is a problem that it cannot withstand the necessary high-speed rotation.

JP-A-6-343913

  The present invention has been made in order to solve the above-described problems, and in addition to the double centrifugal force caused by rotation and revolution of the material to be kneaded, precession motion (oscillating shape around the rotation center axis) Rotation of the rotating rotating body can be performed at high speed in a rotating / revolving agitation / defoaming device in which the whole is kneaded by applying a moving motion due to the vertical kneading action due to the centrifugal force due to revolution. Another object of the present invention is to provide a highly viscous material to be kneaded.

Rotating / revolving agitator in which a vertically long kneaded material storage container in which a material to be kneaded is stored in a rotating rotating body that rotates around a rotating shaft provided at a radial position from the center is disposed obliquely with respect to the rotating shaft. The defoaming device, wherein the rotation axis is parallel to the revolution axis and the rotation body forms a syringe container mounting space by a plurality of hollow bearings arranged vertically below the rotation axis. And a syringe container support hole penetrating the syringe container mounting space in an inclined state intersecting the rotation axis at a position deviated from the center of the rotation rotator. This The features.

  Further, in the present invention, the precession can be efficiently performed because the fulcrum of the precession in the syringe container attached to the rotating body is located above the center position in the length direction.

  Furthermore, the material to be kneaded is housed in a vertically long syringe, and the material to be kneaded material container is housed in a vertically long syringe having an opening with a lid that can be opened and closed at the upper end. By storing the material to be kneaded stored in the syringe in the opening so as to be able to be put in and out, it is possible to support the material to be kneaded in a stable state and cope with high-speed rotation.

Explanatory drawing which shows a prior art example.

  FIG. 1 and FIG. 2 show a preferred embodiment of the present invention. A rotation / revolution type stirring / defoaming device is connected to a rotating shaft of an electric motor 5 installed on a base 4 via a rotation controller 51. The rotating shaft 6 constituting the revolution shaft A is erected. The rotating shaft 6 has a double shaft structure of a central shaft 61 and a tubular shaft 62 disposed around the central shaft 61, and the disk-shaped revolution rotating body 1 is fixed to the tubular shaft 62 so as to be horizontally rotatable. A center gear 61 penetrates the revolution rotator 1 and is fixed with a rotation gear 63 composed of a spur gear disposed along the upper surface of the revolution rotator 1. The revolution rotator 1 and the rotation gear 63 are respectively separated. Speed control is possible.

  In addition, the revolution rotating body 1 has fitting insertion holes 11 and 11 formed at symmetric positions in the radial direction with a predetermined distance across the rotation shaft 6 (revolution axis A) disposed at the center. Rotating rotating bodies 2 and 2 are rotatably inserted into the insertion holes 11 and 11 through bearings 7 and 7, respectively.

  The rotating rotators 2 and 2 have rotating teeth 21 and 21 meshing with a rotating gear 63 fixed to the rotating shaft 6 of the revolving rotating member 1 at the upper part thereof, and rotating gears fixed to the rotating shaft 6. The rotation rotators 2 and 2 are rotated by the driving force of the revolution rotator 1 by transmitting the rotation 63 through the rotating teeth 21 and 21.

  The rotation rotating bodies 2 and 2 are formed with a support hole 8 for supporting a vertically long and long kneaded material storage container 9 containing a material to be kneaded 10 described later at the center. In particular, the support hole 8 is formed such that the center axis C intersects the rotation axis B located at the center of the rotation rotating body 2 at a predetermined inclination angle (for example, around 20 degrees).

  Moreover, in this Embodiment, the said bearings 7 and 7 are the said rotation rotation arrange | positioned in the tubular support part 71 suspended along the lower surface in the fitting insertion holes 11 and 11 of the revolution rotation body 1, and the inside. It is formed by a pair of bearing bearings 72 and 72 that are vertically arranged from the body 2 and are arranged in the vertical direction, and can be rotated in a stable state even when the material to be kneaded is supported, for example, at 2500 rpm or higher. Yes.

  FIG. 3 shows an object to be kneaded 10 and an object to be kneaded container 9 used in the present embodiment. The object to be kneaded 10 particularly suitable for use connects a semiconductor device to a printed wiring portion, for example. A highly viscous material filled in a vertically long syringe, such as a solder paste used for soldering, an epoxy resin adhesive used in various manufacturing processes, and a coating agent. The container 9 includes a storage container body 91 having a top opening for storing the material to be kneaded 10 and a lid body 92 that is crowned by, for example, screw fitting to the storage container body, and the storage container body 91 is the rotating body. 2 has an outer diameter that can be fitted into support holes 8 and 8 formed so as to intersect with a predetermined inclination angle (for example, around 70 degrees) with respect to the rotation axis B located at the center of 2 and is crowned. Lid 92 is a larger diameter than that.

  Therefore, in this embodiment, as shown in FIGS. 1 and 2, the material to be kneaded 10 is attached to the rotating rotating body 2 by being inserted into the support holes 8 and 8 until the lower surface of the lid 92 abuts. In particular, in the present embodiment, the material storage container 9 (the material to be mixed 10) is inserted into and supported by the support hole 8 at a position higher than the center in the length direction and is disposed on the rotating rotating body 2. The center-of-gravity position G of the kneaded material storage container 9 is in the bearings 72 and 72, so that it is possible to perform precession at a high speed in a very stable state.

  In the present embodiment having the above-described configuration, the support holes 8, 8 are formed in the rotating body 2 with the kneaded material storage containers 9, 9 storing the material to be kneaded 10 having a high viscosity such as a paste stored in a syringe. Until the lid 92 contacts the top surface of the rotating rotating body 2 and rotates the motor 5 at a predetermined speed to rotate the rotating rotating body 1 and the rotating gear 63 to rotate to engage the rotating teeth 21 and 21. Is rotated at high speed.

  At this time, in this embodiment, as shown in FIG. 4A, the objects to be kneaded containers 9 and 9 (the objects to be kneaded 10 and 10) are supported by the rotating rotating body 2 at the upper portion and the center of gravity G 1 is arranged in the bearing 7 as shown in FIG. 1, so that the conventional speed of about 1,000 rpm can be rotated at a high speed of 2,000 to 3,000 rpm.

  Further, in the present embodiment, the conventional rotation / revolution type is such that the kneaded material storage container 9 (kneaded material 10) shown in FIG. 4 (b) is supported by the rotating rotating body 2 at the central portion in the length direction. Unlike the agitation / defoaming apparatus of FIG. 4, the material to be kneaded container 9 (the material to be kneaded 10) is supported on the upper side as shown in FIG. A large precession can be expected in the whole, especially downward.

  As shown in FIG. 4C, it is possible to support the material to be kneaded container 9 (the material to be kneaded 10) on the rotating rotator 2 below, but mechanically rotating the rotating member as described above. Means for rotating 2 at high speed is difficult.

  In the present invention, it is also important to stir the high-viscosity material and defoam the fine bubbles in the material to be kneaded 10 at the time of stirring. The force increases as the support angle to the rotating rotator 2 approaches the horizontal direction from the vertical direction, and decreases as the support angle approaches the vertical direction. Increasing the support angle allows movement in the vertical direction even at a low rotation. That is, the force for kneading the material to be kneaded 10 becomes closer to the horizontal and the centrifugal force of the revolving shaft rotating body 1 is increased to reduce the rotation speed of the rotating rotating body 2, but the defoaming is closer to the vertical. Makes it easier to push out bubbles.

  FIG. 5A shows the support angle (approximately 70 degrees) of the material to be kneaded with respect to the revolution axis A in the present embodiment, and the support angle of the conventional example shown in FIG. 6 in FIG. 5B. When the defoaming performance was compared with (approximately 45 degrees), for example, when the material to be kneaded 10 was rotated at 2,000 rpm using an epoxy adhesive before curing, in the case of the present embodiment, approximately 5 minutes. Although the bubbles almost disappeared due to the revolution, no defoaming effect was observed in the conventional example even after the revolution for 6 minutes. From these, it was confirmed that the support angle with respect to the revolution axis A (spinning axis B) is preferably about 70 degrees.

  In this embodiment, the rotation center 1 (revolution axis A) is sandwiched between the revolution rotator 1 and a pair of rotation rotators 2 and 2 are provided at the target position. The number and arrangement of the rotating rotators 2 are not limited as employed in the rotating / revolving stirring / defoaming device. For example, the rotating rotator 1 is centered on the revolving axis A such as using a balance weight. As long as it does not cause a problem in rotation at high speed without being displaced.

  In the present embodiment, the conventional rotation / revolution type agitation / defoaming apparatus is used for the paste-like material to be kneaded 10 that is difficult to stir, for example, contained in a syringe. Needless to say, high performance can be achieved even when a conventionally known material to be kneaded that is not accommodated is directly accommodated in the material to be kneaded container 9.

  Furthermore, in the present embodiment, the kneaded material storage container 9 is inserted obliquely downward into the support container 8 formed in the rotating rotating body 2 until the large-diameter lid body 92 comes into contact with the storage container main body 91 until it rotates. It is possible to support the removably without being particularly fixed by the centrifugal force. However, for example, a fixing means with a release by spring fitting or the like is disposed between the storage container main body 91 and the support hole 8. Other means are also applicable.

  In this embodiment, the rotating rotator 2 has rotating teeth 21 and 21 meshing with a rotating gear 63 attached to the center shaft 61 on the outer periphery, and the gear 63 attached to the rotating shaft 61 is a revolving rotator. Since the rotating rotators 2 and 2 are rotated by the driving force of the revolving rotating body 1 by transmitting through the rotating teeth 21 and 21 by the rotation of 1, the rotating / revolving stirring / defoaming device is provided. The present invention is advantageous in that it can be configured compactly and efficiently with a small number of parts. However, the present invention is not limited to this. For example, the rotating rotating body 2 is not a gear but other transmission means such as a belt transmission, or It goes without saying that other driving means such as individual driving means can be used.
