Description

  The present invention relates to a container in which a mesh member used for fluid filtration or the like is sandwiched, and a method for manufacturing the same.

  Conventionally, as a container used for an oil strainer or the like for filtering oil, there is a container in which a mesh member is sandwiched between a pair of resin containers (see, for example, Patent Document 1).

  This conventional container forms an internal space between the upper member formed with an inlet into which oil is introduced and the upper member and is joined to the upper member, and the oil introduced from the inlet is discharged. And a mesh member sandwiched between the joint surface of the upper member and the joint surface of the lower member. In this container, a flange portion through which a bolt is inserted is formed on the outer peripheral portion of the upper member and the lower member, and by bolting the flange portion, a space between the joint surface of the upper member and the joint surface of the lower member is formed. The joint surface of the upper member and the joint surface of the lower member are joined together with the mesh member sandwiched therebetween.

Japanese Patent No. 4711911

  However, since the conventional container needs to enlarge a flange part in order to bolt an upper member and a lower member, there was a limit in saving space.

  In this regard, it is also conceivable to join the upper member and the lower member by vibration welding. However, if the upper member and the lower member are vibrated for vibration welding, there is a problem that the mesh member sandwiched between the joint surface of the upper member and the joint surface of the lower member is twisted. In addition, even if the upper member and the lower member are vibrated to vibrate the upper member and the lower member, the joint surface of the upper member and the lower portion of the upper member are simply scraped by the mesh member. The joint surface of the member cannot be welded.

  For this reason, in such a container in which the mesh member is sandwiched between the upper member and the lower member, it is extremely difficult to weld the upper member and the lower member.

  Then, an object of this invention is to provide the container which can aim at space saving, and its manufacturing method.

  As a result of earnest research on the above problems, the present inventor uses laser welding, and without causing problems such as vibration welding, the bonding surface of the first container part and the bonding surface of the second container part The knowledge that the 1st container part and the 2nd container part can be welded in the state where the mesh member was inserted in between was acquired.

  That is, the container according to the present invention forms an internal space between the first container part made of resin in which an inflow port into which a fluid flows is formed and the first container part joined to the first container part. The second container part made of resin in which a discharge port for discharging the fluid flowing in from the inlet is formed, and the mesh sandwiched between the joint surface of the first container part and the joint surface of the second container part And a joining surface of the first container part and a joining surface of the second container part are welded outside the mesh member.

  According to the container according to the present invention, since the first container part and the second container part are joined by welding of the joining surface of the first container part and the joining surface of the second container part, space saving of the container is achieved. Can be achieved. Moreover, since the welding of the joining surface of the first container part and the joining surface of the second container part is performed outside the mesh member, the influence of the mesh member on the welding of the first container part and the second container part is affected. Can be small. Thereby, for example, even if the mesh member is pressed by the passing fluid, it is possible to prevent the first container part and the second container part from being broken by this.

  In the present invention, the joining surface of the first container part and the joining surface of the second container part may be continuously welded along the entire periphery of the mesh member on the outside of the mesh member. . Thereby, the welding intensity | strength of a 1st container part and a 2nd container part can further be improved.

  The container manufacturing method according to the present invention includes a resin-made first container part in which an inflow port into which a fluid flows is formed, and a drain that is joined to the first container part and from which the fluid that flows in from the inflow port is discharged. A method of manufacturing a container having a resin-made second container part in which an outlet is formed, and a mesh member sandwiched between a joint surface of the first container part and a joint surface of the second container part, A mesh member is sandwiched between the joining surface of the first container part and the joining surface of the second container part, and the joining surface of the first container part and the joining surface of the second container part are laser welded outside the mesh member. To do.

  According to the container manufacturing method of the present invention, the bonding surface of the first container part and the bonding surface of the second container part are welded by laser welding the bonding surface of the first container part and the bonding surface of the second container part. Even in a state where the mesh member is sandwiched between the first container part and the second container part, the space of the container can be saved. In this case, since it is not necessary to vibrate the first container part and the second container part unlike vibration welding, the mesh member can be prevented from being twisted. In addition, the first container portion and the second container portion are hardly affected by the mesh member by laser welding the bonding surface of the first container portion and the bonding surface of the second container portion outside the mesh member. Can be welded. Furthermore, the container manufactured thereby also reduces the influence of the mesh member on the welding between the first container part and the second container part. For example, even if a load is applied to the mesh member as the fluid passes, This can prevent the first container part and the second container part from being broken.

  According to the present invention, space saving can be achieved.

Examples of such additive substances include, but are not limited to, nigrosine, naphthalocyanine, and the like. The colorant etc. which are chosen may be contained.

  The second container part 3 is formed with a discharge port 31 for discharging the oil that has flowed into the internal space. The formation position of the discharge port 31 is not particularly limited, and can be set at an arbitrary position of the second container part 3. In the drawing, a discharge port 31 is formed at a position facing the opening of the second container portion 3.

  A joint portion 32 that forms an opening and is joined to the first container portion 2 is formed at the opening side edge of the second container portion 3. A joining surface 33 that is joined to the joining surface 23 of the first container part 2 is formed in the joining part 32. The joining surface 33 is formed in a substantially planar shape from the viewpoint of improving the joining property with the first container part 2. Further, the joint portion 32 is formed in a flange shape that extends to the outside of the second container portion 3 along the joint surface 33 from the viewpoint of increasing the area of the joint surface 33. In addition, the junction part 32 does not necessarily need to be formed in a flange shape.

  As shown in FIGS. 3 to 6, the mesh member 4 is disposed between the first container part 2 and the second container part 3, and the oil flowing out from the inlet 21 of the first container part 2 is removed. It is filtered and discharged from the outlet 31 of the second container part 3. The mesh member 4 is formed in a thin mesh structure by a metal wire or a polyamide (PA) mesh. Examples of the metal forming the mesh member 4 include stainless steel (SUS). The thickness of the mesh member 4 is not specifically limited, For example, it can be 0.005 mm or more and 0.800 mm or less. In this case, the thickness of the mesh member 4 is preferably 0.01 mm or more and 0.50 mm or less, and more preferably 0.05 mm or more and 0.30 mm or less. The mesh structure and the mesh size of the mesh member 4 are not particularly limited, and can be appropriately set depending on the use of the oil strainer 1 and the like.

  The mesh member 4 is formed in a shape that covers all of the opening of the first container part 2 and the opening of the second container part 3, and the peripheral part thereof is the joint surface 23 of the first container part 2 and the second container part 3. Are sandwiched between the joint surface 33 and the joint surface 33. For this reason, the mesh member 4 is in contact with the joint surface 23 of the first container part 2 on one side (front side) of the peripheral part, and the second side (back side) of the peripheral part is second. It is in contact with the joint surface 33 of the container part 3.

  Further, the peripheral edge 41 of the mesh member 4 is formed smaller than the peripheral edge 24 of the joint surface 23 of the first container part 2 and the peripheral edge 34 of the joint surface 33 of the second container part 3. It arrange | positions inside the peripheral edge 24 of the surface 23, and the peripheral edge 34 of the joining surface 33 of the 2nd container part 3. FIG. For this reason, a region where the mesh member 4 is not sandwiched is formed outside the mesh member 4 between the joint surface 23 of the first container part 2 and the joint surface 33 of the second container part 3.

  In the oil strainer 1, the joint surface 23 of the first container part 2 and the joint surface 33 of the second container part 3 are welded on the outside of the mesh member 4. That is, the weld part 5 that welds the joint surface 23 of the first container part 2 and the joint surface 33 of the second container part 3 is not penetrated by the mesh member 4. However, the mesh member 4 and the welded portion 5 may be in contact with each other or may be separated from each other. The welded portion 5 is obtained by cooling and hardening the resin melted from at least one of the first container portion 2 and the second container portion 3 when the first container portion 2 and the second container portion 3 are laser-welded. is there.

  It is preferable that welding of the 1st container part 2 and the 2nd container part 3 is performed continuously along the outer periphery of the mesh member 4 on the outer side of the mesh member 4. FIG. That is, it is preferable that the welded portion 5 formed outside the mesh member 4 is continuously formed along the entire periphery of the mesh member 4. However, welding with the 1st container part 2 and the 2nd container part 3 does not necessarily need to be performed continuously, and may be performed intermittently. That is, the welding part 5 does not necessarily need to be formed continuously, and may be formed intermittently.

  Next, the joining surface 23 of the first container part 2 and the joining surface 33 of the second container part 3 are laser-welded outside the peripheral edge of the mesh member 4. In laser welding, first, the first container portion 2 is irradiated with a laser so that the laser is focused near the joint surface 23 on the outside of the mesh member 4. Then, the resin near the focal point is melted, and the melted resin flows out of the mesh member 4 from the joint surface 23 of the first container part 2 to the joint surface 33 of the second container part 3. Thereafter, the laser irradiation is stopped and the melted resin is cooled and cured. Then, between the joint surface 23 of the first container part 2 and the joint surface 33 of the second container part 3, the joint surface 23 of the first container part 2 and the joint surface of the second container part 3 outside the mesh member 4. The welded portion 5 welded to 33 is formed.

Since the part 3 is joined, space saving of the oil strainer 1 can be achieved. Moreover, since the welding of the joining surface 23 of the first container part 2 and the joining surface 33 of the second container part 3 is performed outside the mesh member 4, the first container part 2 and the second container part 3 The influence of the mesh member 4 on welding can be reduced. Thereby, for example, even if the mesh member 4 is pressed by the passing oil, it is possible to prevent the first container part 2 and the second container part 3 from being broken by this.

  Moreover, since the joining surface 23 of the first container part 2 and the joining surface 33 of the second container part 3 are continuously welded along the entire peripheral edge of the mesh member 4 on the outer side of the mesh member 4, the first The welding strength between the container part 2 and the second container part 3 is improved.

  Moreover, according to the manufacturing method of the oil strainer 1 which concerns on this embodiment, the joining surface 23 of the 1st container part 2 and the 2nd container part are obtained by laser welding the 1st container part 2 and the 2nd container part 3. The first container part 2 and the second container part 3 can be welded even when the mesh member 4 is sandwiched between the three joint surfaces 33. In this case, unlike the vibration welding, it is not necessary to vibrate the first container part 2 and the second container part 3, so that the mesh member 4 can be prevented from being twisted. Moreover, the first container part 2 is hardly affected by the mesh member 4 by laser welding the joining surface 23 of the first container part 2 and the joining surface 33 of the second container part 3 outside the mesh member 4. And the second container part 3 can be welded.

  In addition, by adding a substance that converts laser light to heat when laser light is applied to at least one of the first container part 2 and the second container part 3, the bonding surface 23 of the first container part 2 While being able to laser-weld easily with the joint surface 33 of the two container parts 3, high welding intensity | strength can be obtained.
