Description

[Technical field]

[0001] The present invention relates to a coating apparatus. [Background technology]

[0002] Conventionally, automobiles are provided with a casing for housing components of a drivetrain that transmits the driving force of an engine. The casing is manufactured, for example, by bonding a first casing and a second casing together, and an accommodation space for housing the components of the drivetrain is formed inside the bonded first casing and second casing.

[0003] Lubricating oil is introduced into the storage space inside the casing to prevent damage to each component of the drive train. To prevent the lubricating oil from leaking from the bonding surface between the first casing and the second casing, a liquid gasket is applied to the bonding surface as a sealant.

[0004] For example, Patent Document 1 discloses that a liquid gasket is applied to the bonding surface between magnesium alloy parts to ensure oil sealing between the bonding surfaces. In Patent Document 1, an uneven shape is formed on at least one bonding surface of the magnesium alloy parts to improve the oil sealing between the bonding surfaces.

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The specific dimensions, materials, numerical values, etc. shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0012] FIG. 1 is a schematic diagram showing the configuration of a coating apparatus 100 according to a first embodiment. As shown in FIG. 1, the coating apparatus 100 includes a drive mechanism 110, a nozzle 120, a removal mechanism 130, and a control device 140. The coating apparatus 100 is an apparatus that coats an adhesive LG on a surface 220 of a member 210. Here, the member 210 is, for example, a metal member made of metal. In addition, an oxide film OF is formed on the surface 220 of the member 210. The surface 220 of the member 210 has a planar shape, for example, a plane parallel to the horizontal direction.

[0013] The driving mechanism 110 is disposed vertically above the surface 220 of the member 210. The driving mechanism 110 holds the nozzle 120 and the removal mechanism 130, and moves the nozzle 120 and the removal mechanism 130 together. For example, the driving mechanism 110 is configured to be able to move the nozzle 120 and the removal mechanism 130 in a first direction R along the surface 220 of the member 210.

[0014] The nozzle 120 is provided vertically below the driving mechanism 110. The nozzle 120 has an outlet 122 for discharging the adhesive LG. The outlet 122 of the nozzle 120 is disposed at a position vertically above and spaced apart from the surface 220 of the member 210. The outlet 122 of the nozzle 120 is disposed opposite to the surface 220 of the member 210.

[0015] In the first embodiment, the adhesive LG is, for example, a liquid gasket. However, the adhesive LG is not limited thereto, and may be, for example, an epoxy adhesive, an acrylic adhesive, a silicone adhesive, or the like, as long as it can bond and seal the surface 220 between the pair of members 210.

[0016] The removal mechanism 130 is provided vertically below the drive mechanism 110. The removal mechanism 130 is arranged alongside the nozzle 120 in the first direction R. The removal mechanism 130 is arranged on the first direction R side relative to the nozzle 120. In other words, the removal mechanism 130 is arranged forward of the nozzle 120 in the first direction R. Conversely, the nozzle 120 is arranged rearward of the removal mechanism 130 in the first direction R.

[0017] The removal mechanism 130 has a contact member 132. The contact member 132 is a member that contacts the oxide film OF on the surface 220 of the member 210. For example, the contact member 132 is a grindstone. The grindstone comes into contact with the oxide film OF and moves, thereby removing the oxide film OF formed on the surface 220 of the member 210. In the first embodiment, the contact member 132 is a grindstone, but is not limited to this as long as it is a member that can remove the oxide film OF. For example, the contact member 132 may be a cutting tool, a file, or the like. The removal mechanism 130 may also be a mechanism that removes the oxide film OF by irradiating the surface 220 with a laser.

[0018] The control device 140 is electrically connected to the driving mechanism 110 and the nozzle 120, and controls the driving mechanism 110 and the nozzle 120. The control device 140 includes one or more processors 140a and one or more memories 140b. The processor 140a includes, for example, a CPU (Central Processing Unit). The memory 140b includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a storage element that stores programs and calculation parameters used by the CPU. The RAM is a storage element that temporarily stores data such as variables and parameters used in processing executed by the CPU. The processor 140a cooperates with the programs included in the memory 140b and executes the programs included in the memory 140b to realize various processes including the processes described below. Specifically, the processor 140a controls the driving mechanism 110 to execute a process of controlling the movement direction and movement speed of the nozzle 120 and the removal mechanism 130, and the relative positions of the nozzle 120 and the removal mechanism 130 with respect to the surface 220. Furthermore, the processor 140a controls the nozzle 120 to execute a process for controlling the discharge timing and the discharge amount of the adhesive LG discharged from the discharge port 122. Hereinafter, the operations of the drive mechanism 110, the nozzle 120, and the removal mechanism 130 will be described.

[0019] First, the processor 140a controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 130 to a position vertically above the surface 220 of the member 210. The processor 140a also controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 130 to a position where the abutting member 132 of the removal mechanism 130 abuts against the oxide film OF on the surface 220. When the abutting member 132 abuts against the oxide film OF, the outlet 122 of the nozzle 120 is spaced vertically above the surface 220.

[0020] The processor 140a controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 130 in a first direction R. When the contact member 132 moves in the first direction R, the movement of the contact member 132 scrapes off the oxide film OF, and the oxide film OF on the surface 220 is removed.

[0021] Furthermore, when the movement of the nozzle 120 and the removal mechanism 130 is started, the processor 140a controls the nozzle 120 to discharge the adhesive LG from the outlet 122 of the nozzle 120. The nozzle 120 is located on the rear side of the removal mechanism 130 in the first direction R. Therefore, the adhesive LG discharged from the outlet 122 of the nozzle 120 is applied onto the surface 220 from which the oxide film OF has been removed by the removal mechanism 130. After the application of the adhesive LG, another member is bonded to the member 210. The other member may be a member having the same configuration as the member 210, or may be a member having a different configuration. An example in which the other member is a member having the same configuration as the member 210 will be described below.

[0022] Here, when adhesive LG is applied onto the oxide film OF on the surface 220 of the member 210, there is a risk that the oxide film OF may reduce the adhesion between the member 210 and another member bonded to the member 210. By applying adhesive LG to the surface 220 from which the oxide film OF has been removed by the removal mechanism 130, it is possible to suppress the reduction in adhesion between the member 210 and another member. In particular, by bonding a pair of members 210 from which the oxide film OF on the surface 220 has been removed by the removal mechanism 130, it is possible to suppress the reduction in adhesion.

[0023] Note that even if the oxide film OF on the surface 220 is removed by the removal mechanism 130, a new oxide film OF is naturally generated when the surface 220 from which the oxide film OF has been removed comes into contact with oxygen in the air. For this reason, it is preferable that the distance between the removal mechanism 130 and the nozzle 120 is small. Therefore, it is preferable that the nozzle 120 is adjacent to the removal mechanism 130 on the rear side in the first direction R. However, the nozzle 120 and the removal mechanism 130 may be separated by a predetermined distance, and it is preferable that the predetermined distance is a small value in order to suppress the generation of a new oxide film OF.

[0024] In the first embodiment, the transmission case is constructed by applying adhesive LG to the surfaces 220 of the pair of members 210 from which the oxide film OF has been removed, and bonding them together. That is, the pair of members 210 in the first embodiment are components that constitute the transmission case. The transmission case is constructed by a pair of members 210 that are divided in the vertical direction. An accommodation space is formed inside the pair of members 210, and the components of the transmission and oil are accommodated in the accommodation space. The adhesive LG, which is a liquid gasket, seals the space between the pair of members 210 to prevent the oil in the accommodation space from leaking out to the outside.

[0025] FIG. 2 is a schematic top view of the member 210 according to the first embodiment. As shown in FIG. 2, the member 210 has a ring-shaped surface 220. An adhesive LG is applied in a ring shape on the ring-shaped surface 220. The processor 140a moves the nozzle 120 and the removal mechanism 130 along the circumferential direction of the surface 220 to remove the oxide film OF from the ring-shaped surface 220, and applies an annular adhesive LG to the surface 220 from which the oxide film OF has been removed. When the contact member 132 of the removal mechanism 130 moves over the surface 220, a part of the surface 220 is scraped by the contact member 132, and a fine linear groove is formed on the surface 220. The fine linear groove is formed so as to extend along the circumferential direction of the surface 220 as the contact member 132 moves.

[0026] In the first embodiment, the circumferential direction of the surface 220 is the first direction R. The circumferential direction of the surface 220 is a direction intersecting the width direction of the surface 220. Specifically, the circumferential direction of the surface 220 is a direction perpendicular to the width direction of the member 210. The groove formed by the abutting member 132 is formed to extend along the circumferential direction of the surface 220. Therefore, when the oil contained in the accommodation space S of the member 210 moves from the inner circumferential surface 230 side toward the outer circumferential surface 240 side via the surface 220, the movement of the oil can be restricted. As a result, the oil is less likely to leak out of the member 210.

[0027] Furthermore, if a scratch extending from the inner circumferential surface 230 side toward the outer circumferential surface 240 side is formed on the surface 220, the abutment member 132 moves along the circumferential direction of the surface 220, whereby the surface 220 is polished and the scratch formed on the surface 220 can be eliminated.

[0028] 3 is a schematic diagram showing the configuration of a coating apparatus 1000 according to the second embodiment. Note that components substantially the same as those of the coating apparatus 100 according to the first embodiment are denoted by the same reference numerals and will not be described. As shown in FIG. 3, the coating apparatus 1000 includes a drive mechanism 110, a nozzle 120, a removal mechanism 1130, and a control device 140.

[0029] In the second embodiment, a surface 1220 of a member 1210 has a step. Specifically, the surface 1220 has a first plane 1222, an inclined surface 1224, and a second plane 1226. The first plane 1222 has a planar shape and is located vertically above the second plane 1226.

[0030] The inclined surface 1224 has a planar shape and connects the first plane 1222 and the second plane 1226. One end of the inclined surface 1224 is connected to the first plane 1222, and the other end of the inclined surface 1224 is connected to the second plane 1226. One end of the inclined surface 1224 is located vertically above the other end of the inclined surface 1224, and is inclined vertically downward from one end of the inclined surface 1224 to the other end.

[0031] The second plane 1226 has a planar shape and is located vertically below the first plane 1222. The first plane 1222 and the second plane 1226 are, for example, planes parallel to the horizontal direction. The inclined plane 1224 is, for example, an inclined plane inclined with respect to the horizontal direction.

[0032] The removal mechanism 1130 has an abutting member 132 and a pressing mechanism 1134. The pressing mechanism 1134 presses the abutting member 132 toward the surface 1220. In the second embodiment, the pressing mechanism 1134 includes a spring 1136. The pressing force generated when the spring 1136 is compressed presses the abutting member 132 toward the surface 1220. However, without being limited thereto, the pressing mechanism 1134 may include a hydraulic, pneumatic, or electromagnetic actuator capable of moving the abutting member 132, instead of the spring 1136. In that case, in the pressing mechanism 1134, the amount of movement of the abutting member 132 may be controlled by the processor 140a.

[0033] In the second embodiment, first, the processor 140a controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 1130 to a position vertically above the first flat surface 1222 of the member 1210. The processor 140a also controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 1130 to a position where the abutting member 132 of the removal mechanism 1130 abuts against the oxide film OF on the first flat surface 1222. When the abutting member 132 abuts against the oxide film OF, the outlet 122 of the nozzle 120 is spaced vertically above the surface 1220.

[0034] The processor 140a controls the driving mechanism 110 to move the nozzle 120 and the removal mechanism 1130 in the first direction R. When the contact member 132 moves in the first direction R, the movement of the contact member 132 scrapes off the oxide film OF, and the oxide film OF on the first flat surface 1222 is removed.

[0035] Furthermore, when the movement of the nozzle 120 and the removal mechanism 1130 starts, the processor 140a controls the nozzle 120 to discharge the adhesive LG from the discharge port 122 of the nozzle 120. The nozzle 120 is located on the rear side of the removal mechanism 1130 in the first direction R. Therefore, the adhesive LG discharged from the discharge port 122 of the nozzle 120 is applied onto the first plane 1222 from which the oxide film OF has been removed by the removal mechanism 1130.

[0036] Fig. 4 is a schematic diagram showing the removal mechanism 1130 removing the oxide film OF on the inclined surface 1224. Fig. 5 is a schematic diagram showing the removal mechanism 1130 removing the oxide film OF on the second flat surface 1226.

[0037] As shown in FIG. 4, when the abutting member 132 moves from the first flat surface 1222 to the inclined surface 1224, the abutting position between the abutting member 132 and the surface 1220 changes vertically downward. However, since the removing mechanism 1130 includes the pressing mechanism 1134, the abutting member 132 can be moved to follow the inclined surface 1224 in response to the change in the vertical height of the surface 1220. Therefore, even if the vertical height of the surface 1220 changes, the abutting state between the abutting member 132 and the surface 1220 can be maintained. At this time, the spring 1136 stretches, and the overall length of the spring 1136 becomes longer. Furthermore, the abutting member 132 moves vertically downward by the amount of the stretch of the spring 1136.

[0038] As a result, when the abutting member 132 moves in the first direction R, the movement of the abutting member 132 can scrape off the oxide film OF on the inclined surface 1224, and the oxide film OF on the inclined surface 1224 can be removed. As shown in FIG. 5, in the second flat surface 1226 having a different height from the first flat surface 1222, the abutting member 132 can scrape off the oxide film OF on the second flat surface 1226, and the oxide film OF on the second flat surface 1226 can be removed, similarly to the inclined surface 1224. Then, the adhesive LG can be applied to the inclined surface 1224 and the second flat surface 1226 from which the oxide film OF has been removed by the removing mechanism 1130. By applying the adhesive LG to the surface 1220 from which the oxide film OF has been removed by the removing mechanism 1130, a decrease in the adhesion between the members 1210 can be suppressed.

[0039] Furthermore, as shown in Figures 4, 5, and 6, even if a step is provided on surface 1220 of member 1210, the oxide film OF on surface 1220 having the step can be removed by causing abutment member 132 to follow the shape of surface 1220 using pressing mechanism 1134.

[0040] Fig. 6 is a schematic diagram showing the configuration of a coating apparatus 2000 according to the third embodiment. Components substantially the same as those of the coating apparatus 100 according to the first embodiment are denoted by the same reference numerals and will not be described. As shown in Fig. 6, the coating apparatus 2000 includes a drive mechanism 110, a nozzle 120, a removal mechanism 130, a control device 140, and a gas injection mechanism 2100. Fig. 6 shows the coating apparatus 2000 as viewed from the front.

[0041] Fig. 7 is a schematic diagram showing the coating apparatus 2000 as viewed from the side. As shown in Fig. 6 and Fig. 7, the gas injection mechanism 2100 is arranged next to the removal mechanism 130 in a direction perpendicular to the first direction R, i.e., in the width direction of the member 210. Specifically, the gas injection mechanism 2100 is arranged on the inner circumferential surface 230 side of the member 210 with respect to the removal mechanism 130.

[0042] The gas injection mechanism 2100 injects gas A toward the contact portion between the oxide film OF and the contact member 132. The oxide film OF scraped off by the contact member 132 remains on the surface 220 as fine granular foreign matter FM. The gas A injected from the gas injection mechanism 2100 reaches the contact portion between the oxide film OF and the contact member 132, and blows away the foreign matter FM generated when the oxide film OF is removed by the contact member 132 toward the outer circumferential surface 240 of the member 210. This makes it possible to reduce the foreign matter FM from being caught between the surface 220 from which the oxide film OF has been removed and the adhesive LG. As a result, it is possible to suppress a decrease in the adhesion between the members 210.

[0043] Moreover, the gas injection mechanism 2100 injects the gas A toward the outer circumferential surface 240 side of the member 210. Therefore, it is possible to prevent the foreign matter FM blown away by the gas A from entering the accommodation space S on the inner circumferential surface 230 side of the member 210. In the third embodiment, the gas A is, for example, air. However, the gas A is not limited to air as long as it is a gas capable of blowing away the foreign matter FM.

[0044] 8 is a schematic diagram showing the configuration of a coating apparatus 3000 according to the fourth embodiment. Note that components substantially the same as those of the coating apparatus 100 according to the first embodiment and the coating apparatus 1000 according to the second embodiment are denoted by the same reference numerals and will not be described. As shown in FIG. 8, the coating apparatus 3000 includes a drive mechanism 3110, a nozzle 120, a removal mechanism 130, and a control device 140.

[0045] In the fourth embodiment, similarly to the second embodiment, a surface 1220 of a member 1210 has a step. Specifically, the surface 1220 has a first flat surface 1222, an inclined surface 1224, and a second flat surface 1226.

[0046] The drive mechanism 3110 includes a nozzle drive member 3112 and a removal mechanism drive member 3114. The nozzle drive member 3112 is connected to the nozzle 120 and moves the nozzle 120 in a direction approaching and away from the surface 1220. The removal mechanism drive member 3114 is connected to the removal mechanism 130 and moves the removal mechanism 130 in a direction approaching and away from the surface 1220. The nozzle drive member 3112 and the removal mechanism drive member 3114 are formed by, for example, hydraulic, pneumatic, or electromagnetic actuators.

[0047] The processor 140a controls the amount of movement of the nozzle 120 by the nozzle drive member 3112. Furthermore, the processor 140a controls the amount of movement of the removal mechanism 130 by the removal mechanism drive member 3114. The processor 140a controls the nozzle drive member 3112 and the removal mechanism drive member 3114 independently. Note that the nozzle drive member 3112 may move the nozzle 120 in a direction approaching and moving away from the removal mechanism 130. Furthermore, the removal mechanism drive member 3114 may move the removal mechanism 130 in a direction approaching and moving away from the nozzle 120.

[0048] In the fourth embodiment, first, the processor 140a controls the driving mechanism 3110 to move the nozzle 120 and the removal mechanism 130 to a position vertically above the first flat surface 1222 of the member 1210. The processor 140a also controls the driving mechanism 3110 to move the nozzle 120 and the removal mechanism 130 to a position where the abutting member 132 of the removal mechanism 130 abuts against the oxide film OF on the first flat surface 1222. When the abutting member 132 abuts against the oxide film OF, the outlet 122 of the nozzle 120 is spaced vertically above the surface 1220 by a predetermined distance.

[0049] The processor 140a controls the driving mechanism 3110 to move the nozzle 120 and the removal mechanism 130 in the first direction R. When the contact member 132 moves in the first direction R, the movement of the contact member 132 scrapes off the oxide film OF, and the oxide film OF on the first flat surface 1222 is removed.

[0050] Furthermore, when the movement of the nozzle 120 and the removal mechanism 130 starts, the processor 140a controls the nozzle 120 to discharge the adhesive LG from the discharge port 122 of the nozzle 120. The nozzle 120 is located on the rear side of the removal mechanism 130 in the first direction R. Therefore, the adhesive LG discharged from the discharge port 122 of the nozzle 120 is applied onto the first plane 1222 from which the oxide film OF has been removed by the removal mechanism 130.

[0051] Fig. 9 is a schematic diagram showing the removal mechanism 130 removing the oxide film OF on the inclined surface 1224. Fig. 10 is a schematic diagram showing the removal mechanism 130 removing the oxide film OF on the second flat surface 1226.

[0052] 9, when the abutment member 132 moves from the first flat surface 1222 to the inclined surface 1224, the abutment position between the abutment member 132 and the surface 1220 changes vertically downward. However, since the drive mechanism 3110 includes the removal mechanism drive member 3114, the abutment member 132 can be moved to follow the inclined surface 1224 in accordance with the change in the vertical height of the surface 1220. Therefore, even if the vertical height of the surface 1220 changes, the abutment state between the abutment member 132 and the surface 1220 can be maintained.

[0053] At this time, the nozzle 120 has not yet reached the inclined surface 1224, and is positioned on the first plane 1222, which has a constant height. Therefore, the processor 140a controls the nozzle drive member 3112 so that the height of the outlet 122 of the nozzle 120 remains constant. This allows the adhesive LG to be applied to the surface 1220 from a constant height, and the variation in the applied state of the adhesive LG on the surface 1220 can be reduced.

[0054] When the abutting member 132 moves in the first direction R, the movement of the abutting member 132 can scrape off the oxide film OF on the inclined surface 1224, thereby removing the oxide film OF on the inclined surface 1224. Also, as shown in Fig. 10, even on a second flat surface 1226 having a different height from the first flat surface 1222, the abutting member 132 can scrape off the oxide film OF on the second flat surface 1226, similarly to the inclined surface 1224, thereby removing the oxide film OF on the second flat surface 1226.

[0055] At this time, the processor 140a controls the nozzle drive member 3112 so that the distance between the outlet 122 of the nozzle 120 and the inclined surface 1224 and the second flat surface 1226 is a constant, predetermined distance. This allows the adhesive LG to be applied from a height of a constant, predetermined distance on the first flat surface 1222, the inclined surface 1224, and the second flat surface 1226 of the surface 1220, and reduces variation in the applied state of the adhesive LG on the surface 1220.

[0056] In addition, an adhesive LG can be applied onto the inclined surface 1224 and the second flat surface 1226 from which the oxide film OF has been removed by the removal mechanism 130. By applying the adhesive LG to the surface 1220 from which the oxide film OF has been removed by the removal mechanism 130, a decrease in the adhesion between the members 1210 can be suppressed.

[0057] 8, 9, and 10, even if a step is provided on the surface 1220 of the member 1210, the removal mechanism driving member 3114 can cause the contact member 132 to follow the shape of the surface 1220. Therefore, even if the pressing mechanism 1134 of the second embodiment is not provided, the contact member 132 can be kept in contact with the surface 1220 to continuously remove the oxide film OF.

[0058] Furthermore, even if a step is provided on the surface 1220 of the member 1210, the nozzle driving member 3112 can cause the height of the outlet 122 of the nozzle 120 to follow the shape of the surface 1220. Therefore, the distance between the outlet 122 of the nozzle 120 and the surface 1220 becomes constant, so that the adhesive LG can be applied continuously from a constant height, and the variation in the application state of the adhesive LG on the surface 1220 can be reduced.

[0059] Although the embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can think of various modified or altered examples within the scope of the claims, and it is understood that such examples also naturally belong to the technical scope of the present invention.

[0060] For example, in the above embodiment, an example has been described in which the members 210 and 1210 are transmission cases. However, the present invention is not limited to this, and the members 210 and 1210 may be case members such as an engine casing to which a cylinder block and an oil pan are joined. Furthermore, the members 210 and 1210 are not limited to case members, and may be, for example, solid rod members or block bodies.

[0061] Further, in the above embodiment, an example in which the driving mechanism 110 moves the nozzle 120 and the removal mechanisms 130 and 1130 has been described. However, this is not limited thereto, and the driving mechanism 110 may be configured to be able to move the members 210 and 1210. Alternatively, the driving mechanism 110 may be configured to be able to move all of the members 210 and 1210, the nozzle 120, and the removal mechanisms 130 and 1130. For example, the processor 140a may move the members 210 and 1210 such that the nozzle 120 and the removal mechanisms 130 and 1130 move relative to the members 210 and 1210 along the circumferential direction of the surface 220. In this manner, the processor 140a may move the members 210 and 1210, the nozzle 120, and the removal mechanisms 130 and 1130 relatively.

[0062] In the above embodiment, an example has been described in which the driving mechanism 110, 3110 moves the nozzle 120 and the removal mechanism 130, 1130 together. However, the present invention is not limited to this, and the driving mechanism 110, 3110 may be configured to be able to move the nozzle 120 and the removal mechanism 130, 1130 independently. For example, the processor 140a may move the removal mechanism 130, 1130 along the circumferential direction of the surface 220, and move the nozzle 120 following the removal mechanism 130, 1130 so that the distance between the nozzle 120 and the removal mechanism 130, 1130 is constant. The processor 140a may also move the nozzle 120 following the removal mechanism 130, 1130 so that the distance between the nozzle 120 and the removal mechanism 130, 1130 becomes longer or shorter over time.
