Description

本発明は、自動変速機用流体フィルタの製造方法に関し、さらに詳しくは、各ケース部材及び側板を密着性を高めて当接させて溶着手段により接合することができる生産性に優れた自動変速機用流体フィルタの製造方法に関する。   The present invention relates to a method of manufacturing a fluid filter for an automatic transmission, and more specifically, an automatic transmission with excellent productivity that can bring each case member and a side plate into contact with each other with improved adhesion and can be joined by welding means. The present invention relates to a method for manufacturing a fluid filter for an automobile.

従来の自動変速機用流体フィルタとして、樹脂製の上側ケース部材と、この上側ケース部材との間で濾過室を形成する樹脂製の下側ケース部材と、この濾過室内に配置されるひだ折り状の濾材及び該濾材の縁端を保持する樹脂製の保持枠を有するフィルタエレメントと、を備えてなる流体フィルタが一般に知られている（例えば、特許文献１及び２参照
）。 As a conventional fluid filter for an automatic transmission, an upper case member made of resin, a lower case member made of resin that forms a filtration chamber between the upper case member, and a fold-fold shape disposed in the filtration chamber And a filter element having a resin-made holding frame that holds the edge of the filter medium are generally known (see, for example, Patent Documents 1 and 2).

上記特許文献１には、例えば、図９に示すように、振動溶着により上側ケース部材１０２、下側ケース部材１０３及び保持枠１１０の３部材を接合することが開示されている。
また、上記特許文献２には、レーザ溶着により上側ケース部材、下側ケース部材及び保持枠の３部材を接合することが開示されている。 For example, as shown in FIG. 9, the above-mentioned Patent Document 1 discloses joining three members, that is, an upper case member 102, a lower case member 103, and a holding frame 110 by vibration welding.
Patent Document 2 discloses that three members, that is, an upper case member, a lower case member, and a holding frame are joined by laser welding.

しかし、上記特許文献１では、例えば、図１０に示すように、振動溶着時に発生するバリ溜め１０７を各ケース部材１０２，１０３に設ける必要があり、各ケース部材１０２，１０３の外周側から外方に突出するフランジ部１０８の幅が約１０ｍｍとなり、小型化を図ることができない。   However, in Patent Document 1, for example, as shown in FIG. 10, it is necessary to provide a burr reservoir 107 generated at the time of vibration welding in each case member 102, 103, and outward from the outer peripheral side of each case member 102, 103. The width of the flange portion 108 protruding to about 10 mm is about 10 mm, and the size cannot be reduced.

一方、上記特許文献２では、レーザ溶着を採用することにより、振動溶着を採用するものに比べて、小型化を図ることができる。しかし、上記特許文献２では、レーザ溶着を採用しているため、成形誤差等により各ケース部材及び保持枠のレーザ接合面の密着性が低い場合には、レーザ溶着により３部材を接合できない恐れがある。
また、上記特許文献１及び２では、通常、溶着手段により３部材を接合し、その後工程で流体フィルタのリーク試験（溶着部の漏れ試験）を行うようにしている。そのため、接合工程とリーク試験工程との２工程が必要となり、生産効率が低い。 On the other hand, in the said patent document 2, size reduction can be achieved by employ | adopting laser welding compared with what employ | adopts vibration welding. However, in the above-mentioned Patent Document 2, since laser welding is adopted, there is a possibility that the three members cannot be joined by laser welding when the adhesion of the laser joining surfaces of the case members and the holding frame is low due to molding errors or the like. is there.
In Patent Documents 1 and 2, usually, three members are joined by welding means, and a leak test of the fluid filter (a leak test of the welded portion) is performed in the subsequent process. For this reason, two steps of a joining step and a leak test step are required, and the production efficiency is low.

本発明の自動変速機用流体フィルタの製造方法によると、フィルタ仮組体の濾過室内を負圧吸引した状態で、溶着手段により上側ケース部材、下側ケース部材及び側板を同時に接合する工程を備えるので、濾過室内の負圧吸引によって、上側ケース部材、下側ケース部材及び側板の３部材を密着性を高めて当接させて溶着手段により接合することができる。また、接合工程では、濾過室内の負圧吸引を利用してリーク試験を行うようにしたので、溶着手段により３部材を接合する際にリーク試験を行うことができ、生産効率を高めることができる。
他の本発明の自動変速機用流体フィルタの製造方法によると、フィルタ仮組体が収容された密閉容器内を正圧印加した状態で、溶着手段により上側ケース部材、下側ケース部材及び側板を同時に接合する工程を備えるので、密閉容器内の正圧印加によって、上側ケース部材、下側ケース部材及び側板の３部材を密着性を高めて当接させて溶着手段により接合することができる。また、接合工程では、密閉容器内の正圧印加を利用してリーク試験を行うようにしたので、溶着手段により３部材を接合する際にリーク試験を行うことができ、生産効率を高めることができる。
また、前記溶着手段がレーザ溶着である場合は、振動溶着を採用するものに比べて、フィルタの小型化を図ることができる。
また、前記側板の外周面には外側に向かって尖形状に突出する突出部が形成されており、前記上側ケース部材の周側壁の下端側には、外側から内側に向かって斜め上方に傾斜して延びる上側傾斜面が形成されており、前記下側ケース部材の周側壁の上端側には、外側から内側に向かって斜め下方に傾斜して延びる下側傾斜面が形成されており、前記フィルタ仮組体を形成する工程では、前記上側ケース部材の前記上側傾斜面と前記突出部の上側傾斜面とが当接されると共に、前記下側ケース部材の前記下側傾斜面と前記突出部の下側傾斜面とが当接される場合には、上側ケース部材及び側板のレーザ接合箇所と下側ケース部材及び側板のレーザ接合箇所とを近接して配置することができる。そのため、レーザ光として出力の比較的小さなものを使用でき、生産効率を更に高めることができる。
また、前記上側ケース部材の前記上側傾斜面と前記突出部の上側傾斜面とのうちの少なくとも一方の傾斜面には、他方の傾斜面に向かって突出する突起が形成されている場合は、傾斜面同士を当接させたときに突起が変形することにより傾斜面同士をより密着させて当接させることができる。また、突起により傾斜面が反り返った状態で当接されるため、レーザ溶着の際に傾斜面同士が強く押し付けられた状態で接合することができる。その結果、上側ケース部材及びフィルタエレメントにより形成されるクリーン側の濾過室に必要な密閉性をより確実に確保することができる。
さらに、前記上側ケース部材の周側壁の下端側には、前記上側当接面の外側で水平に延びる上側水平面が形成されており、前記下側ケース部材の周側壁の上端側には、前記下側当接面の外側で水平に延びる下側水平面が形成されており、前記フィルタ仮組体を形成する工程では、前記上側ケース部材の前記上側水平面と前記下側ケース部材の前記下側水平面とが当接される場合は、側板及びレーザ溶着部は、上側ケース部材及び下側ケース部材で覆われて外部に露出しないため、意匠性を高めることができる。 According to the method for manufacturing a fluid filter for an automatic transmission of the present invention, the method includes the step of simultaneously joining the upper case member, the lower case member, and the side plate by the welding means in a state where the filter chamber of the filter temporary assembly is sucked with negative pressure. Therefore, the three members of the upper case member, the lower case member, and the side plate can be brought into contact with each other with high pressure by negative pressure suction in the filtration chamber and can be joined by the welding means. Further, in the joining process, the leak test is performed using negative pressure suction in the filtration chamber, so that the leak test can be performed when the three members are joined by the welding means, and the production efficiency can be increased. .
According to another method for manufacturing a fluid filter for an automatic transmission according to the present invention, an upper case member, a lower case member, and a side plate are attached by welding means in a state where a positive pressure is applied to the inside of a sealed container in which a filter temporary assembly is accommodated. Since the step of joining at the same time is provided, by applying positive pressure in the sealed container, the three members of the upper case member, the lower case member and the side plate can be brought into contact with high adhesion and can be joined by the welding means. Moreover, in the joining process, since the leak test is performed using positive pressure application in the sealed container, the leak test can be performed when the three members are joined by the welding means, thereby improving the production efficiency. it can.
Further, when the welding means is laser welding, the filter can be reduced in size as compared with those employing vibration welding.
In addition, a protruding portion that protrudes outward is formed on the outer peripheral surface of the side plate, and the lower end side of the peripheral side wall of the upper case member is inclined obliquely upward from the outside toward the inside. An upper inclined surface that extends downwardly, and a lower inclined surface that extends obliquely downward from the outside toward the inside is formed on the upper end side of the peripheral side wall of the lower case member, and the filter In the step of forming the temporary assembly, the upper inclined surface of the upper case member and the upper inclined surface of the protruding portion are brought into contact with each other, and the lower inclined surface of the lower case member and the protruding portion are When the lower inclined surface is brought into contact with each other, the laser joining location of the upper case member and the side plate and the laser joining location of the lower case member and the side plate can be arranged close to each other. Therefore, a laser beam having a relatively small output can be used, and the production efficiency can be further increased.
In addition, when a protrusion protruding toward the other inclined surface is formed on at least one of the upper inclined surface of the upper case member and the upper inclined surface of the protruding portion, the inclined surface is inclined. By deforming the projection when the surfaces are brought into contact with each other, the inclined surfaces can be brought into closer contact with each other. Further, since the inclined surfaces are brought into contact with each other in a state of being warped by the protrusion, the inclined surfaces can be joined in a state where they are strongly pressed during laser welding. As a result, it is possible to more reliably ensure the sealing performance required for the clean filtration chamber formed by the upper case member and the filter element.
Further, an upper horizontal surface that extends horizontally outside the upper abutment surface is formed on the lower end side of the peripheral side wall of the upper case member, and the upper end side of the peripheral side wall of the lower case member is A lower horizontal plane extending horizontally outside the side contact surface is formed, and in the step of forming the filter temporary assembly, the upper horizontal plane of the upper case member and the lower horizontal plane of the lower case member Since the side plate and the laser welded portion are covered with the upper case member and the lower case member and are not exposed to the outside, the design can be improved.

なお、上記自動変速機用流体フィルタとしては、例えば、（１）上側ケース部材及び下側ケース部材がレーザ透過性を有しており、側板がレーザ吸収性を有している形態（例えば、図３等参照）、（２）上側及び下側ケース部材のうちの一方のケース部材がレーザ透過性を有しており、他方のケース部材がレーザ吸収性を有しており、側板がレーザ吸収性を有している形態（例えば、図７等参照）等を挙げることができる。また、これら樹脂部材としては、例えば、ポリスチレン（ＰＳ）、低密度ポリエチレン（ＬＤＰＥ）、ポリカーボネート（ＰＣ）等の非晶性樹脂、ポリプロピレン（ＰＰ）、ポリブチレンテレフタレート（ＰＢＴ）、ポリエチレンテレフタレート（ＰＥＴ）、ポリアミド（ＰＡ）、ポリアセタール（ＰＯＭ）等の結晶性樹脂などを挙げることができる。これらのうち、レーザ透過性といった観点から、非晶性樹脂であることが好ましい。一方、レーザ吸収性といった観点から、非晶性樹脂及び結晶性樹脂のどちらであってもよい。さらに、上側ケース部材、下側ケース部材及び側板が同種の樹脂であることが好ましい。これら３部財の熱膨張率を同じにして接合性をより高め得るためである。   Examples of the automatic transmission fluid filter include (1) a mode in which the upper case member and the lower case member have laser permeability, and the side plate has laser absorption (for example, FIG. 3), (2) one of the upper and lower case members has laser transparency, the other case member has laser absorption, and the side plate has laser absorption. (For example, refer to FIG. 7 and the like). Examples of these resin members include amorphous resins such as polystyrene (PS), low density polyethylene (LDPE), and polycarbonate (PC), polypropylene (PP), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET). And crystalline resins such as polyamide (PA) and polyacetal (POM). Among these, from the viewpoint of laser transmittance, an amorphous resin is preferable. On the other hand, from the viewpoint of laser absorbability, either an amorphous resin or a crystalline resin may be used. Furthermore, it is preferable that the upper case member, the lower case member, and the side plate are the same kind of resin. This is because the thermal expansion coefficient of these three-part goods can be made the same to further improve the bondability.

上記「フィルタ仮組体形成工程」は、上側ケース部材と下側ケース部材との間に側板を挟持してなるフィルタ仮組体を形成する工程である限り、その形成形態、タイミング等は特に問わない。   As long as the “filter temporary assembly forming step” is a step of forming a filter temporary assembly in which a side plate is sandwiched between an upper case member and a lower case member, its formation form, timing, etc. are not particularly limited. Absent.

上記フィルタ仮組体形成工程としては、例えば、上記側板の外周面には外側に向かって尖形状に突出する突出部が形成されており、上側ケース部材の周側壁の下端側には、外側から内側に向かって斜め上方に傾斜して延びる上側傾斜面が形成されており、下側ケース部材の周側壁の上端側には、外側から内側に向かって斜め下方に傾斜して延びる下側傾斜面が形成されており、上記フィルタ仮組体形成工程では、上側ケース部材の上側傾斜面と突出部の上側傾斜面とが当接されると共に、下側ケース部材の下側傾斜面と突出部の下側傾斜面とが当接される形態（例えば、図３等参照）を挙げることができる。この上側ケース部材の上側傾斜面及び突出部の上側傾斜面の傾斜角度（θ１）は、例えば、１０〜６０度（好ましくは２０〜４５度）であることができる（例えば、図３等参照）。また、下側ケース部材の下側傾斜面及び突出部の下側傾斜面の傾斜角度（θ２）は、例えば、２０〜６０度（好ましくは３０〜４５度）であることができる（例えば、図３等参照）。上記傾斜角度（θ１）は、例えば、上記傾斜角度（θ２）以下であることができる。これにより、接合面をより強く押し付ける力（濾過室の負圧吸引／正圧印加時の分力）が作用するため、確実な溶着面が得られる。その結果、リークの発生をより確実に防止できる。なお、上記「外側」及び「内側」とは、フィルタの外側及び内側を意図している。   As the filter temporary assembly forming step, for example, a protruding portion that protrudes outward is formed on the outer peripheral surface of the side plate, and the lower end side of the peripheral side wall of the upper case member is formed from the outside. An upper inclined surface extending obliquely upward toward the inside is formed, and a lower inclined surface extending obliquely downward from the outside toward the inside is formed on the upper end side of the peripheral side wall of the lower case member. In the filter temporary assembly forming step, the upper inclined surface of the upper case member and the upper inclined surface of the protruding portion are brought into contact with each other, and the lower inclined surface of the lower case member and the protruding portion are The form (for example, refer FIG. 3 etc.) with which a lower side inclined surface is contact | abutted can be mentioned. The inclination angle (θ1) of the upper inclined surface of the upper case member and the upper inclined surface of the protrusion can be, for example, 10 to 60 degrees (preferably 20 to 45 degrees) (for example, see FIG. 3 and the like). . Further, the inclination angle (θ2) of the lower inclined surface of the lower case member and the lower inclined surface of the protruding portion can be, for example, 20 to 60 degrees (preferably 30 to 45 degrees) (for example, FIG. (See 3 etc.). The inclination angle (θ1) can be equal to or less than the inclination angle (θ2), for example. As a result, a force that strongly presses the joint surface (negative pressure suction in the filtration chamber / component force during application of positive pressure) acts, so that a reliable weld surface can be obtained. As a result, the occurrence of leakage can be prevented more reliably. The “outer side” and “inner side” mean the outer side and the inner side of the filter.

上述の形態では、例えば、上側ケース部材の上側傾斜面と突出部の上側傾斜面とのうちの少なくとも一方の傾斜面には、他方の傾斜面に向かって突出する突起が形成されていることができる（例えば、図８等参照）。また、上述の形態では、例えば、下側ケース部材の下側傾斜面と突出部の下側傾斜面とのうちの少なくとも一方の傾斜面には、他方の傾斜面に向かって突出する突起が形成されていることができる（例えば、図８等参照）。   In the above-described embodiment, for example, at least one of the upper inclined surface of the upper case member and the upper inclined surface of the protruding portion may have a protrusion that protrudes toward the other inclined surface. (For example, see FIG. 8 etc.). Further, in the above-described embodiment, for example, a protrusion that protrudes toward the other inclined surface is formed on at least one of the lower inclined surface of the lower case member and the lower inclined surface of the protruding portion. (See, for example, FIG. 8).

上述の形態では、例えば、上側ケース部材の周側壁の下端側には、上側当接面の外側で水平に延びる上側水平面が形成されており、下側ケース部材の周側壁の上端側には、下側当接面の外側で水平に延びる下側水平面が形成されており、フィルタ仮組体形成工程では、上側ケース部材の上側水平面と下側ケース部材の下側水平面とが当接されることができる（例えば、図６等参照）。   In the above-mentioned form, for example, the upper horizontal surface extending horizontally outside the upper contact surface is formed on the lower end side of the peripheral side wall of the upper case member, and on the upper end side of the peripheral side wall of the lower case member, A lower horizontal surface extending horizontally outside the lower contact surface is formed, and in the filter temporary assembly forming step, the upper horizontal surface of the upper case member and the lower horizontal surface of the lower case member are in contact with each other. (See, for example, FIG. 6).

上述の形態では、例えば、後述する接合工程において、フィルタ仮組体の外側方から、上側ケース部材の上側傾斜面（又は上側水平面）と下側ケース部材の下側傾斜面（又は下側水平面）との境界部位に向かってレーザ光を照射して上側ケース部材、下側ケース部材及び側板の３部材を接合することができる。   In the above-described embodiment, for example, in the joining step described later, from the outer side of the filter temporary assembly, the upper inclined surface (or upper horizontal surface) of the upper case member and the lower inclined surface (or lower horizontal surface) of the lower case member. The three members of the upper case member, the lower case member, and the side plate can be joined by irradiating the laser beam toward the boundary portion.

上記「接合工程」は、上記フィルタ仮組体の濾過室内を負圧吸引した状態で、溶着手段により上側ケース部材、下側ケース部材及び側板を同時に接合する工程である限り、その接合形態、タイミング等は特に問わない。この接合工程では、濾過室内の負圧吸引を利用してリーク試験（溶着部の漏れ試験）が行われる。この負圧は、例えば、−１〜−１００ＫＰａであることができる。これにより、各ケース部材及び側板の密着性を高め得ると共に、リーク試験を簡易に行うことができる。また、上記リーク試験の種類としては、例えば、差圧式、直圧式、流量式等を挙げることができる。さらに、上記溶着手段としては、例えば、レーザ溶着、振動溶着、熱板による溶着等を挙げることができる。これらのうち、溶着手段がレーザ溶着であることが好ましい。   As long as the “joining step” is a step of joining the upper case member, the lower case member, and the side plate at the same time by the welding means in a state where negative pressure is sucked in the filtration chamber of the filter temporary assembly, the joining form and timing thereof Etc. are not particularly limited. In this joining step, a leak test (a leak test of the welded portion) is performed using negative pressure suction in the filtration chamber. This negative pressure can be, for example, -1 to -100 KPa. Thereby, while being able to improve the adhesiveness of each case member and a side plate, a leak test can be performed easily. Examples of the type of leak test include a differential pressure type, a direct pressure type, and a flow rate type. Furthermore, examples of the welding means include laser welding, vibration welding, and welding with a hot plate. Of these, the welding means is preferably laser welding.

（２）オイルフィルタの製造方法
次に、上記構成のオイルフィルタ１の製造方法について説明する。
図３に示すように、上側ケース部材２と下側ケース部材３との間に側板１０を挟持させてフィルタ仮組体１３を形成する。このとき、上側ケース部材２及び突出部１１の上側傾斜面２ｃ，１１ａ同士が当接されており、下側ケース部材３及び突出部１１の下側傾斜面３ｃ，１１ｂ同士が当接されている。 (2) Manufacturing method of oil filter Next, the manufacturing method of the oil filter 1 of the said structure is demonstrated.
As shown in FIG. 3, the filter temporary assembly 13 is formed by sandwiching the side plate 10 between the upper case member 2 and the lower case member 3. At this time, the upper case member 2 and the upper inclined surfaces 2c and 11a of the protruding portion 11 are in contact with each other, and the lower case member 3 and the lower inclined surfaces 3c and 11b of the protruding portion 11 are in contact with each other. .

次に、図４に示すように、フィルタ仮組体１３において、オイル流入部６ｂを止め栓１４で塞ぎ、オイル流出部６ａを連絡管１５を介してポンプ等の負圧発生源１６に連絡する。この連絡管１５の途中には圧力センサ１７が装着されている。そして、負圧発生源１６の作用でフィルタ仮組体１３の濾過室４内を負圧吸引し、その状態より、上側ケース部材２及び下側ケース部材３の境界部位１９に向かってレーザトーチ２０から水平方向にレーザ光を照射し、このレーザトーチ２０をフィルタ仮組体１３の全周に沿って移動させる。すると、上側ケース部材２及び突出部１１の上側傾斜面２ｃ，１１ａ同士、並びに下側ケース部材３及び突出部１１の下側傾斜面３ｃ，１１ｂ同士はレーザ溶着部Ｗ（図２参照）により接合される。次いで、圧力センサ１７の測定値に基づいてオイルフィルタ１のリーク試験（レーザ溶着部Ｗの漏れ試験）が行われる。   Next, as shown in FIG. 4, in the filter temporary assembly 13, the oil inflow portion 6 b is closed with a stopper plug 14, and the oil outflow portion 6 a is connected to a negative pressure generation source 16 such as a pump via a connecting pipe 15. . A pressure sensor 17 is attached in the middle of the communication pipe 15. Then, the negative pressure generating source 16 sucks negative pressure in the filter chamber 4 of the filter temporary assembly 13, and from this state, the laser torch 20 moves toward the boundary portion 19 between the upper case member 2 and the lower case member 3. Laser light is irradiated in the horizontal direction, and the laser torch 20 is moved along the entire circumference of the filter temporary assembly 13. Then, the upper case member 2 and the upper inclined surfaces 2c and 11a of the projecting portion 11 and the lower case member 3 and the lower inclined surfaces 3c and 11b of the projecting portion 11 are joined by the laser welding portion W (see FIG. 2). Is done. Next, a leak test of the oil filter 1 (leak test of the laser welded portion W) is performed based on the measurement value of the pressure sensor 17.

（３）実施例１の効果
本実施例１のオイルフィルタの製造方法によると、フィルタ仮組体１３の濾過室４内を負圧吸引した状態で、レーザ溶着により上側ケース部材２、下側ケース部材３及び側板１０を同時に接合する工程を備えるので、濾過室４内の負圧吸引によって、上側ケース部材２、下側ケース部材３及び側板１０の３部材を密着性を高めて当接させてレーザ溶着により接合することができる。また、レーザ溶着を採用しているので、従来のように振動溶着を採用するものに比べて、小型化を図ることができる。また、接合工程では、濾過室４内の負圧吸引を利用してリーク試験を行うようにしたので、レーザ溶着により３部材を接合する際にリーク試験を行うことができ、生産効率を高めることができる。 (3) Effects of Example 1 According to the method of manufacturing an oil filter of Example 1, the upper case member 2 and the lower case are formed by laser welding in a state where the inside of the filter chamber 4 of the filter temporary assembly 13 is sucked with negative pressure. Since the process of joining the member 3 and the side plate 10 at the same time is provided, the three members of the upper case member 2, the lower case member 3 and the side plate 10 are brought into contact with each other by suction with a negative pressure in the filtration chamber 4. Bonding can be performed by laser welding. In addition, since laser welding is employed, it is possible to reduce the size as compared with the conventional method employing vibration welding. Further, in the joining process, the leak test is performed by using the negative pressure suction in the filtration chamber 4, so that the leak test can be performed when the three members are joined by laser welding, thereby improving the production efficiency. Can do.

さらに、本実施例１では、側板１０の外周面には外側に向かって尖形状に突出する突出部１１を形成し、上側ケース部材２の周側壁２ｂの下端側には、外側から内側に向かって斜め上方に傾斜して延びる上側傾斜面２ｃを形成し、下側ケース部材３の周側壁３ｂの上端側には、外側から内側に向かって斜め下方に傾斜して延びる下側傾斜面３ｃを形成し、フィルタ仮組体１３を形成する工程では、上側ケース部材２及び突出部１１の上側傾斜面２ｃ，１１ａ同士を当接させると共に、下側ケース部材３及び突出部１１の下側傾斜面３ｃ，１１ｂ同士を当接させるようにしたので、上側ケース部材２及び側板１０のレーザ接合箇所と下側ケース部材３及び側板１０のレーザ接合箇所とを近接して配置することができる。そのため、レーザ光として出力の比較的小さなものを使用でき、生産効率を更に高めることができる。   Furthermore, in the first embodiment, a protruding portion 11 that protrudes outward in the shape of a point is formed on the outer peripheral surface of the side plate 10, and the lower end side of the peripheral side wall 2 b of the upper case member 2 is directed from the outside to the inside. An upper inclined surface 2c extending obliquely upward is formed, and a lower inclined surface 3c extending obliquely downward from the outside toward the inside is formed on the upper end side of the peripheral side wall 3b of the lower case member 3. In the step of forming the filter temporary assembly 13, the upper case member 2 and the upper inclined surfaces 2 c and 11 a of the protruding portion 11 are brought into contact with each other, and the lower case member 3 and the lower inclined surface of the protruding portion 11 are brought into contact with each other. Since 3c and 11b are made to contact | abut, the laser joining location of the upper case member 2 and the side plate 10 and the laser joining location of the lower case member 3 and the side plate 10 can be closely arranged. Therefore, a laser beam having a relatively small output can be used, and the production efficiency can be further increased.

Further, the resin-made sealed container 24 having laser transparency is connected to a positive pressure generating source 26 such as a compressor through a communication pipe 25. Next, the filter temporary assembly 13 is accommodated in the sealed container 24, and the inside of the sealed container 24 is applied with a positive pressure by the action of the positive pressure generating source 26. From this state, the boundary between the upper case member 2 and the lower case member 3 Laser light is irradiated in a horizontal direction from the laser torch 20 toward the part 19, and the laser torch 20 is moved along the entire circumference of the filter temporary assembly 13. Then, the upper case member 2 and the upper inclined surfaces 2c and 11a of the projecting portion 11 and the lower case member 3 and the lower inclined surfaces 3c and 11b of the projecting portion 11 are joined by the laser welding portion W (see FIG. 2).

本実施例２のオイルフィルタの製造方法によると、上記実施例１のオイルフィルタの製造方法と略同様の作用・効果を奏すると共に、フィルタ仮組体１３が収容された密閉容器２４内を正圧印加した状態で、レーザ溶着により上側ケース部材２、下側ケース部材３及び側板１０を同時に接合する工程を備えるので、密閉容器２４内の正圧印加によって、上側ケース部材２、下側ケース部材３及び側板１０の３部材を密着性を高めて当接させてレーザ溶着により接合することができる。また、レーザ溶着を採用しているので、従来のように振動溶着を採用するものに比べて、小型化を図ることができる。また、接合工程では、密閉容器２４内の正圧印加を利用してリーク試験を行うようにしたので、レーザ溶着により３部材を接合する際にリーク試験を行うことができ、生産効率を高めることができる。 (2) Effects of Example 2 According to the method for manufacturing an oil filter of Example 2, the same effects and advantages as the method for manufacturing the oil filter of Example 1 are achieved, and the temporary filter assembly 13 is accommodated. In the state where a positive pressure is applied in the closed container 24, the upper case member 2, the lower case member 3 and the side plate 10 are simultaneously joined by laser welding. The members 2, the lower case member 3 and the side plate 10 can be brought into contact with each other with improved adhesion and can be joined by laser welding. In addition, since laser welding is employed, it is possible to reduce the size as compared with the conventional method employing vibration welding. Further, in the joining process, the leak test is performed by applying positive pressure in the sealed container 24. Therefore, the leak test can be performed when the three members are joined by laser welding, and the production efficiency is increased. Can do.

尚、本発明においては、上記実施例に限られず、目的、用途に応じて本発明の範囲内で種々変更した実施例とすることができる。即ち、上記実施例１及び２では、フィルタ仮組体１３を形成する工程では、上側ケース部材２及び突出部１１の上側傾斜面２ｃ，１１ａ同士、並びに下側ケース部材３及び突出部１１の下側傾斜面３ｃ，１１ｂ同士のみを当接させる形態を例示したが、これに限定されず、例えば、図６に示すように、上側ケース部材２の周側壁２ａの下端側に、上側当接面２ｃの外側で水平に延びる上側水平面２ｄを形成し、下側ケース部材３の周側壁３ａの上端側には、下側当接面３ｃの外側で水平に延びる下側水平面３ｄを形成し、フィルタ仮組体１３を形成する工程では、上側ケース部材２及び突出部１１の上側傾斜面２ｃ，１１ａ同士、下側ケース部材３及び突出部１１の下側傾斜面３ｃ，１１ｂ同士、並びに上側ケース部材２の上側水平面２ｄ及び下側ケース部材３の下側水平面３ｄを当接させるようにしてもよい。これにより、側板１０及びレーザ溶着部Ｗは、上側ケース部材２及び下側ケース部材３で覆われて外部に露出しないため、意匠性を高めることができる。   In the present invention, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. That is, in the first and second embodiments, in the process of forming the filter temporary assembly 13, the upper case member 2 and the upper inclined surfaces 2 c and 11 a of the protruding portion 11, and the lower case member 3 and the lower portion of the protruding portion 11 are formed. Although the form which contact | abuts only the side inclined surfaces 3c and 11b was illustrated, it is not limited to this, For example, as shown in FIG. 6, an upper side contact surface is formed in the lower end side of the surrounding side wall 2a of the upper case member 2. An upper horizontal surface 2d that extends horizontally outside the lower case member 3 is formed, and a lower horizontal surface 3d that extends horizontally outside the lower contact surface 3c is formed on the upper end side of the peripheral side wall 3a of the lower case member 3. In the step of forming the temporary assembly 13, the upper case member 2 and the upper inclined surfaces 2 c and 11 a of the protruding portion 11, the lower case member 3 and the lower inclined surfaces 3 c and 11 b of the protruding portion 11, and the upper case member 2d horizontal surface 2d and It may be caused to abut the lower horizontal surface 3d of the lower case member 3. Thereby, since the side plate 10 and the laser welding part W are covered with the upper case member 2 and the lower case member 3 and are not exposed to the outside, the design can be improved.

また、上述の形態の場合、例えば、図７に示すように、上側ケース部材２がレーザ透過性を有しており、下側ケース部材３及び側板１０がレーザ吸収性を有しているようにしてもよい。この場合、上側ケース部材２及び下側ケース部材３の水平面２ｄ，３ｄ同士、並びに上側ケース部材２及び突出部１１の傾斜面２ｃ，１１ａ同士がレーザ溶着部Ｗより溶着されることとなる。   Further, in the case of the above-described embodiment, for example, as shown in FIG. 7, the upper case member 2 has laser transparency, and the lower case member 3 and the side plate 10 have laser absorption. May be. In this case, the horizontal surfaces 2d and 3d of the upper case member 2 and the lower case member 3 and the inclined surfaces 2c and 11a of the upper case member 2 and the protruding portion 11 are welded from the laser welding portion W.

さらに、上記実施例１及び２において、例えば、図８に示すように、突出部１１の上側傾斜面１１ａ及び下側傾斜面１１ｂに、上側ケース部材２及び下側ケース部材３の傾斜面２ｃ，３ｃに向かって突出する突起２８を形成するようにしてもよい。これにより、傾斜面１１ａ，２ｃ，１１ｂ，３ｃ同士を当接させたときに突起２８が変形することにより傾斜面１１ａ，２ｃ，１１ｂ，３ｃ同士をより密着させて当接させて接合することができる。また、突起２８により傾斜面１１ａ，１１ｂが反り返った状態で当接されるため、レーザ溶着の際に傾斜面１１ａ，２ｃ，１１ｂ，３ｃ同士が強く押し付けられた状態で接合することができる。その結果、濾過室４のクリーン側４ａ及びダスティ側４ｂに必要な密閉性を確保することができる。   Further, in the first and second embodiments, for example, as shown in FIG. 8, the upper case member 2 and the lower case member 3 have inclined surfaces 2 c, You may make it form the protrusion 28 which protrudes toward 3c. Thereby, when the inclined surfaces 11a, 2c, 11b, and 3c are brought into contact with each other, the projections 28 are deformed so that the inclined surfaces 11a, 2c, 11b, and 3c are brought into closer contact with each other to be joined. it can. Further, since the inclined surfaces 11a and 11b are warped by the protrusions 28, the inclined surfaces 11a, 2c, 11b and 3c can be joined in a state where they are strongly pressed during laser welding. As a result, the sealing property required for the clean side 4a and the dusty side 4b of the filtration chamber 4 can be ensured.
