[0015] <Thermal spraying equipment> A thermal spraying apparatus 10 according to one embodiment of this disclosure will be described below with reference to the drawings.

[0016] Figure 1 is a diagram illustrating the configuration of a thermal spraying apparatus 10 according to one embodiment of the present disclosure. The thermal spraying apparatus 10 consists of a central control panel 101, a thermal spraying machine 103, and peripheral equipment. The peripheral equipment includes a mobile machine 105, a gas supply machine 108, a cooling gas supply machine 109, a rotating machine 113 containing a workpiece (substrate) 111, a first sensor 115, and a second sensor 117. The peripheral equipment may also include a temperature and humidity control machine 121 and a dust collector 123. In this embodiment, the thermal spraying machine 103 consists of a thermal spray torch 102, a thermal spray control machine 106, a raw material feeder 107, and a gas supply machine 108.

[0017] In this embodiment, at least a portion of the thermal spraying machine 103, the mobile unit 105, the cooling gas supply unit 109, the rotating unit 113, the first sensor 115, and the second sensor 117 are installed inside the thermal spraying booth 119 where the thermal spraying process is performed. The temperature and humidity control unit 121 has an air supply duct 122 connected to the inside of the thermal spraying booth 119. The dust collector 123 has an exhaust duct 124 connected to the inside of the thermal spraying booth 119. The thermal spraying apparatus 10 is also equipped with a safety door 125 that allows workers W to enter and exit the inside and outside of the thermal spraying booth 119.

[0018] The central control panel 101 is installed outside the thermal spray booth 119. The central control panel 101 enables the operation of all components of the thermal spraying apparatus 10 collectively. Specifically, the central control panel 101 controls the operation of the thermal sprayer 103, the mobile unit 105, the cooling gas supply unit 109, the rotating unit 113, the first sensor 115, the second sensor 117, the temperature and humidity control unit 121, and the dust collector 123 collectively. The central control panel 101 receives input operations from worker W and controls the operation of each component of the thermal spraying apparatus 10 to execute the thermal spraying process inside the thermal spray booth 119. The central control panel 101 may also control the opening and closing of the safety door 125.

[0019] FIG. 2 is a block diagram for explaining an example of the configuration of the centralized control panel 101 according to the present embodiment. The centralized control panel 101 may include a control unit 201, a storage unit 203, an operation unit 205, a communication unit 207, and a display unit 209. The control unit 201, the storage unit 203, the operation unit 205, the communication unit 207, and the display unit 209 are connected to each other by a bus 211.

[0020] The control unit 201 includes an arithmetic processing circuit such as a CPU. The control unit 201 executes the control program stored in the storage unit 203 by the CPU to control the operation of the spraying device 10 and realize the spraying process by the spraying device 10. In other words, the control unit 201 centrally controls the operations of the spraying machine 103, the moving machine 105, the cooling gas supply machine 109, the rotating machine 113, the first sensor 115, the second sensor 117, the temperature and humidity adjuster 121, and the dust collector 123 that constitute the spraying device 10.

[0021] The storage unit 203 is a storage device such as a ROM, a RAM, or a hard disk. The storage unit 203 stores a control program for realizing the spraying process by the spraying device 10. The control program may be provided in a state of being stored in a computer-readable recording medium such as a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or a semiconductor memory. In this case, the centralized control panel 101 only needs to include a device for reading the recording medium. Further, the storage unit 203 may store settings of the spraying machine 103, the moving machine 105, the cooling gas supply machine 109, the rotating machine 113, the first sensor 115, the second sensor 117, the temperature and humidity adjuster 121, and the dust collector 123 that constitute the spraying device 10. The control program and the settings of each component of the spraying device 10 may be downloaded via a network such as the Internet.

[0022] The operation unit 205 is a device such as an operation panel, operation buttons, a touch panel, etc., and outputs a signal corresponding to the input operation to the control unit 201. The worker W engaged in the spraying operation controls the operation of the spraying device 10 via the operation unit 205. The worker W can instruct the start and stop of the spraying process executed by the spraying device 10 via the operation unit 205. Further, the worker W can appropriately change the settings of the spraying machine 103, the moving machine 105, the cooling gas supply machine 109, the rotating machine 113, the first sensor 115, the second sensor 117, the temperature and humidity adjuster 121, and the dust collector 123 that constitute the spraying device 10 via the operation unit 205.

[0023] The communication unit 207 performs communication with each component of the spraying device 10, namely, the spraying machine 103, the moving machine 105, the cooling gas supply machine 109, the rotating machine 113, the first sensor 115, the second sensor 117, the temperature and humidity adjuster 121, and the dust collector 123 based on the control of the control unit 201. The communication may be wired communication or wireless communication. Incidentally, the function of the storage unit 203 may be realized by an external device that can communicate with the communication unit 207.

[0024] The display unit 209 is a display device such as a liquid crystal display or an organic EL display, and a screen based on the control by the control unit 201 is displayed for the worker W based on the control by the control unit 201. For example, the display unit 209 may display the setting states and operating states of the spraying machine 103, the moving machine 105, the cooling gas supply machine 109, the rotating machine 113, the first sensor 115, the second sensor 117, the temperature and humidity adjuster 121, and the dust collector 123, and the detection results of the first sensor 115 and the second sensor 117.

[0025] Referring to Figure 1, we return to the description of the thermal spraying apparatus 10. The thermal spraying machine 103 includes a thermal spraying torch 102 connected to a mobile machine 105, which will be described later. Based on the thermal spraying control unit 106, the thermal spraying torch 102 sprays thermal spraying material supplied from the raw material feeder 107 and gas supplied from the gas supply unit 108. Thermal spraying by the thermal spraying machine 103 may be gas-type thermal spraying including flame spraying and high-velocity flame spraying, or electric thermal spraying including arc spraying and plasma spraying. The thermal spraying torch 102 melts or partially melts the thermal spraying material with gas or electricity (arc or plasma) to generate thermal spraying particles. The thermal spraying torch 102 accelerates the generated thermal spraying particles with a gas such as compressed air and sprays them onto the workpiece 111 of the rotating machine 113 to form a coating of thermal spraying particles on the surface of the workpiece 111.

[0026] The mobile unit 105 moves the thermal spray torch 102 based on the control of the control unit 201. The mobile unit 105 may be, for example, an industrial robot. Specifically, the mobile unit 105 may be a 6-axis or 7-axis vertical articulated robot. Based on the control of the control unit 201, the mobile unit 105 controls the movement of the thermal spray torch 102 in the forward, backward, up, down, left, and right directions, as well as the angle of the thermal spray torch 102 relative to the surface of the workpiece 111 on the rotating machine 113. For example, when the thermal spraying process by the thermal spraying machine 103 begins, the mobile unit 105 may move the thermal spray torch 102 so that it approaches the workpiece 111 on the rotating machine 113, and may tilt the thermal spray torch 102 to a predetermined angle relative to the surface of the workpiece 111. Also, when the thermal spraying process is completed, the mobile unit 105 may move the thermal spray torch 102 away from the rotating machine 113.

[0027] The thermal spray control unit 106 adjusts the amount of thermal spray material supplied from the raw material feeder 107 to the thermal spray torch 102 based on control by the control unit 201 of the central control panel 101. Similarly, the thermal spray control unit 106 adjusts the amount of working gas supplied from the gas supply unit 108 based on control by the control unit 201 of the central control panel 101 to supply working gas to the thermal spray torch 102. In one embodiment, the amount of thermal spray material supplied directly from the raw material feeder 107 to the thermal spray torch 102 may be adjusted by the control unit 201 of the central control panel 101. Similarly, in one embodiment, the amount of working gas supplied directly from the gas supply unit 108 may be adjusted by the control unit 201 of the central control panel 101.

[0028] The raw material feeder 107 supplies the spray material to the spray torch 102 at a predetermined flow rate based on control by the spray control unit 106. The spray material may be a composite material such as metal, ceramic, polymer, or cermet. In this embodiment, an example is described in which the raw material feeder 107 is installed inside the spray booth 119, but at least a portion of the raw material feeder 107 may be located outside the spray booth 119. The amount of spray material supplied from the raw material feeder 107 to the spray torch 102 may be directly controlled by the control unit 201 of the central control panel 101.

[0029] The gas supply unit 108 supplies working gas to the thermal spray torch 102 via the thermal spray control unit 106 at a predetermined flow rate, based on control by the thermal spray control unit 106. If thermal spraying by the thermal spray machine 103 is gas-powered, the working gas may be a mixed gas containing oxygen (O2) and acetylene. If thermal spraying by the thermal spray machine 103 is electric-powered, the working gas may be a gas such as argon (Ar), helium (He), nitrogen (N2), or hydrogen (H2). The amount of working gas supplied from the gas supply unit 108 may be directly controlled by the control unit 201 of the central control panel 101.

[0030] The cooling gas supply unit 109 supplies cooling gas to the workpiece 111 of the rotating machine 113 at a predetermined flow rate based on the control unit 201. The cooling gas may be nitrogen (N2) gas or argon (Ar) gas. The cooling gas supplied from the cooling gas supply unit 109 cools the thermal spray coating formed on the surface of the workpiece 111.

[0031] The rotating machine 113 includes the workpiece 111. Based on the control of the control unit 201, the rotating machine 113 rotates the workpiece 111 at a predetermined speed. The rotating machine 113 can also rotate the workpiece 111 at a predetermined angle based on the control of the control unit 201. A thermal spray coating is formed on the surface of the workpiece 111 by thermal spray material sprayed from the thermal spray torch 102.

[0032] The first sensor 115 measures the surface temperature of the workpiece 111 based on the control of the control unit 201. The first sensor 115 may be, for example, a radiation temperature sensor. The first sensor 115 transmits the measured surface temperature of the substrate to the control unit 201. Based on the surface temperature of the workpiece 111 obtained from the first sensor 115, the control unit 201 controls the supply of cooling gas from the cooling gas supply unit 109 to the surface of the workpiece 111 so that the surface of the workpiece 111 drops to a predetermined temperature.

[0033] The second sensor 117 measures the temperature and humidity inside the thermal spray booth 119 based on the control of the control unit 201. The second sensor 117 may also be a temperature and humidity sensor. The second sensor 117 transmits the measured temperature and humidity inside the thermal spray booth 119 to the control unit 201. Based on the temperature and humidity inside the thermal spray booth 119 obtained from the second sensor 117, the control unit 201 controls the temperature and humidity controller 121 to maintain the thermal spray booth 119 at predetermined temperatures and humidity levels.

[0034] The temperature and humidity controller 121 adjusts the temperature and humidity inside the thermal spray booth 119 based on the control of the control unit 201.

[0035] The dust collector 123 collects dust generated in the thermal spray booth 119 based on the control of the control unit 201. The dust collector 123 discharges the collected dust outside the thermal spray booth 119 through the exhaust duct 124. The dust is, for example, thermal spray material that did not contribute to film formation. Alternatively, the dust may be thermal spray material that was melted during thermal spraying and then re-solidified upon cooling.

[0036] The safety door 125 allows worker W to enter and exit the thermal spray booth 119. The interlock of the safety door 125 is controlled by the control unit 201.

[0037] The central control panel 101 controls all the components of the thermal spraying apparatus 10 as described above. Although not shown in the diagram, the thermal spraying apparatus 10 may also include a power supply unit that supplies power to each component of the thermal spraying apparatus 10. In this case, the central control panel 101 can control the operation of the power supply unit.

[0038] Although not shown in the diagram, the thermal spraying apparatus 10 may include a compressor for supplying air into the thermal spraying booth 119. The compressor supplies air into the thermal spraying booth 119 so that dust generated in the booth is efficiently collected by the dust collector 123. In this case, the central control panel 101 can control the operation of the compressor and the amount of air supplied.

[0039] Although not shown in the diagram, the thermal spraying apparatus 10 may also include an oxygen concentration sensor for detecting the oxygen concentration inside the thermal spraying booth 119.

[0040] As described above, in this embodiment, the operation of each component of the thermal spraying apparatus 10 is controlled collectively by the central control panel 101. This reduces the complexity of the thermal spraying work and improves safety during the operation. Furthermore, it stabilizes the quality of the thermal spray coating formed on the substrate and improves the reliability of the product.

[0041] <Thermal spraying process> The flow of the thermal spraying process performed by the thermal spraying apparatus 10 according to this embodiment will be described. Figures 3 and 4 are flowcharts showing an example of the thermal spraying process performed by the thermal spraying apparatus 10 according to this embodiment.

[0042] Worker W, engaged in the thermal spraying operation, instructs the thermal spraying device 10 to start the thermal spraying process via the operation unit 205 of the central control panel 101. When the thermal spraying process starts, the control unit 201 of the central control panel 101 locks the safety door 125 (S301) to prevent people from entering the thermal spraying booth 119 during the thermal spraying process. The control unit 201 checks whether the safety door 125 is locked (S302), and if it is not locked properly (S302; No), it returns to the process in S301.

[0043] If the safety door 125 is properly locked (S302; Yes), the control unit 201 checks the operation of the mobile device 105 (S303). If the operation of the mobile device 105 is not normal (S303; No), the worker W checks the settings of the mobile device 105 via the control unit 205 and changes them to the desired settings (S304).

[0044] If the settings of the mobile unit 105 are normal, that is, if the settings of the mobile unit 105 are the desired settings (S303; Yes), the control unit 201 drives the dust collector 123 (S305). Subsequently, the control unit 201 drives the temperature and humidity controller 121 (S306). Based on the temperature and humidity inside the thermal spray booth 119 measured by the second sensor 117, the control unit 201 uses the temperature and humidity controller 121 to maintain the inside of the thermal spray booth 119 at a predetermined temperature and humidity.

[0045] Next, the control unit 201 drives the thermal sprayer 103 (S307). At this time, the supply of working gas from the gas supplyer 108 via the thermal spray control unit 106 is also started. Next, the control unit 201 drives the rotating machine 113 (S308). When the rotating machine 113 is driven, the workpiece 111 starts rotating at a predetermined speed, or at a predetermined angle and predetermined speed.

[0046] Furthermore, the order in which each process from driving the dust collector 123 (S305) to driving the rotating machine 113 (S308) is executed may be changed, or they may be executed simultaneously.

[0047] The control unit 201 then starts supplying cooling gas from the cooling gas supply unit 109 to the workpiece 111 (S309).

[0048] The control unit 201 obtains the temperature of the surface of the workpiece 111, i.e., the surface on which the thermal spray material is applied, as measured by the first sensor 115, and determines whether or not the surface of the substrate is below a predetermined temperature (S310). If the surface of the workpiece 111 is above the predetermined temperature (S310; No), the control unit 201 repeats the process in S310 until the surface of the workpiece 111 is below the predetermined temperature.

[0049] If the surface of the substrate is below a predetermined temperature (S310; Yes), the control unit 201 starts supplying the thermal spray material from the raw material feeder 107 to the thermal spray torch 102 via the thermal spray controller 106 (S311). Next, the mobile unit 105 moves the thermal spray torch 102 to a predetermined position and sprays the thermal spray material onto the surface of the workpiece 111, starting the thermal spray (S312). Here, the predetermined position is the position where the thermal spray torch 102 is close to the workpiece 111 on the rotating machine 113. The control unit 201 may also tilt the thermal spray torch 102 at a predetermined angle with respect to the surface of the workpiece 111 using the mobile unit 105. By thermal spraying, a film of a predetermined thickness of the thermal spray material is formed on the surface of the workpiece 111.

[0050] When a film of a predetermined thickness is formed on the substrate surface, the control unit 201 moves the thermal spray torch 102 away from the workpiece 111 on the rotating machine 113 using the moving machine 105 to stop the thermal spraying (S313).

[0051] The control unit 201 stops the supply of thermal spray material from the raw material feeder 107 to the thermal spray torch 102 via the thermal spray controller 106 (S314). Next, the control unit 201 stops the drive of the thermal spray machine 103 (S315). At this time, the supply of working gas from the gas supply unit 108 via the thermal spray controller 106 is also stopped.

[0052] The control unit 201 obtains the temperature of the surface of the workpiece 111, i.e., the surface of the coating made of the thermal spray material, as measured by the first sensor 115, and determines whether the coating surface is below a predetermined temperature (S316). If the coating surface is above the predetermined temperature (S316; No), the control unit 201 repeats the process in S316 until the coating surface is below the predetermined temperature.

[0053] When the film surface reaches a predetermined temperature or below (S316; Yes), the control unit 201 stops supplying cooling gas from the cooling gas supply unit 109 to the thermal sprayer 103 (S317).

[0054] Subsequently, the control unit 201 stops the drive of the rotating machine 113 (S318).

[0055] Subsequently, the control unit 201 stops the operation of the temperature and humidity controller 121 (S319) and stops the operation of the dust collector 123 (S320). The order in which the operation of the temperature and humidity controller 121 is stopped (S319) and the operation of the dust collector 123 is stopped (S320) may be reversed, or they may be performed simultaneously.

[0056] Finally, the control unit 201 unlocks the safety door 125 (S321) and terminates the thermal spraying process by the thermal spraying device 10.

[0057] As described above, the thermal spraying process performed by the thermal spraying apparatus 10 is centrally controlled by the central control panel 101. This reduces the complexity of the thermal spraying work and improves safety. It also stabilizes the quality of the thermal spray coating formed on the substrate and improves product reliability.

[0058] Even if a person skilled in the art adds, deletes, or modifies components based on the embodiments of the present disclosure described above, as long as it retains the essence of the present invention, it is still considered to be an invention of the present invention. It falls within the scope of "brightness".

[0059] Furthermore, any effects or benefits other than those brought about by the embodiments described above, if they are clear from the description herein or easily predictable to those skilled in the art, are naturally understood to be brought about by the present invention.
