[0085] As shown in Figures 3-17 , the embodiment provides a high-power electron beam physical vapor deposition device for engine blades, which can improve the processing requirements in different vapor deposition processes and improve the convenience and flexibility of vapor deposition processing.

[0086] The electron beam physical vapor deposition device disclosed in the embodiment can simultaneously meet the process requirements of various processing by simultaneously arranging a thermal emission electron gun and a field emission electron gun in the vapor deposition chamber 1. That is, the thermal emission electron gun is used in the scene where the vacuum degree requirement is high and the coating purity requirement is good, and the field emission electron gun is used in the scene where the reaction gas needs to be introduced or the vacuum degree requirement is not high. The two electron guns 2 can be enabled in the corresponding scene to realize vapor deposition processing on the surface of the product. In more cases, when the installation of the two electron guns 2 needs to be adjusted, the required thermal emission electron gun or field emission electron gun can be installed at the electron gun connection position. Since the two electron guns 2 are provided with the same matching structure 201, each electron gun connection position can be installed, thereby realizing convenient interchange. When the vapor deposition device is used, the appropriate electron gun 2 is selected according to the actual process requirement, which not only can effectively guarantee the processing effect of the product, but also can guarantee the effective service life of the electron gun 2.

[0087] As one of the structures of the vapor deposition device provided in the embodiment,

[0088] As shown in Figure 6 , Figure 12 , Figure 13 , Figure 14 , the deposition chamber system includes a vapor deposition chamber 1 provided with a mounting surface 103, at least two electron gun connection positions are arranged on the mounting surface 103, and a plurality of deflection closed structures are arranged in the vapor deposition chamber 1. At least two deflection closed structures correspond to the electron gun connection positions one by one and are used to close or open the wall surface structure of the vapor deposition chamber 1 including the electron gun connection position.

[0089] Preferably, as shown in Figure 14 , in the embodiment, the deposition chamber is hollow in the middle for electron beam physical vapor deposition of parts. The lower part of the deposition chamber has a corresponding target material supply port for connecting a target material automatic evaporation deposition system. The left and right sides have vacuum connection ports and loading docking ports, and corresponding flanges are installed, which are respectively connected to a vacuum pumping system 3 and a loading chamber 4.

[0090] In this embodiment, the sedimentation chamber is provided with an observation window 101 and an inspection door 102.

[0091] As shown in Figure 4, the electron gun connection position is used to connect and fix the thermal emission electron gun or the field emission electron gun. It can be constructed in various forms, and its structure is not limited to one specific type. This embodiment optimizes and adopts one feasible option: the electron gun connection position includes a connection hole provided on the inclined mounting surface 103, and a connection flange is provided at the connection hole; the mating structure 201 of the thermal emission electron gun and the field emission electron gun both include flange joints adapted to the connection flange. When the above scheme is adopted, the mounting surface 103 is an inclined surface, and its inclination angle is set according to requirements. After the electron gun 2 is installed, the electron beam can be emitted towards the designated target material by the set angle. When the target material is heated and evaporated, the evaporated material is deposited on the engine blades in the meteorological deposition chamber to form a film.

[0092] like Figure 14 , Figure 16 As shown, the deflection sealing structure is used to open or close structures within the vapor deposition chamber 1, such as mounting holes and connecting holes. When the electron gun 2 is connected to the vapor deposition chamber 1, its connection position can be controlled by the deflection sealing structure to open or close, thereby opening or closing the channel for the electron beam emitted by the electron gun 2. Various deflection sealing structures can be used, and the structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the deflection sealing structure includes a deflection blade 107, which is driven and deflected by a deflection driver 108. When the deflection blade 107 moves to the closed position, it closes the wall structure including the connecting hole; when the deflection blade 107 moves to the open position, it opens the wall structure including the connecting hole. In this scheme, the deflection driver 108 can be a motor. The motor's output shaft is eccentrically connected to the deflection blade 107, driving the deflection blade 107 to reciprocate, thereby enabling the deflection blade 107 to switch back and forth between the closed and open positions.

[0093] like Figure 12 , Figure 13 As shown, in this embodiment, the vapor deposition chamber 1 is provided with multiple perforated structures, including mounting holes for mounting monitoring components, vacuum connection holes 105 for docking with the vacuum system 3, and loading docking holes 106 for docking with the dual loading system. At some perforated structures where opening and closing need to be controlled, deflection sealing structures are used to control opening or closing.

[0094] like Figure 6 As shown, the second structure of the vapor deposition apparatus provided in this embodiment includes:

[0095] The electron gun 2 includes a thermal emission electron gun and a field emission electron gun that are fitted to the electron gun connection position. The thermal emission electron gun and the field emission electron gun are fitted to the electron gun connection position through the same fitting structure 201 and can be interchanged.

[0096] Preferably, the mounting surface 103 of the deposition chamber forms a 140° angle with the vertical plane. When the thermal emission electron gun and the field emission electron gun are fitted to the mounting surface 103, the electron gun 2 is connected and fixed and can be interchanged.

[0097] Preferably, in this embodiment, two electron gun connection positions are provided on the mounting surface 103, one for connecting a thermionic electron gun and the other for connecting a field electron gun.

[0098] In this embodiment, the electron gun 2 is a high-power electron gun 2 with a power of 250kW, which realizes single-gun multi-beam and high deposition rate.

[0099] like Figure 3 As shown, the third structure of the vapor deposition apparatus provided in this embodiment includes:

[0100] The transmitting power supply 6 includes a thermal emission power supply 6 for powering the thermal emission electron gun and a field emission power supply 6 for powering the field emission electron gun.

[0101] Preferably, the transmitting power supply 6 includes a transformer 8 to achieve efficient power conversion and isolation, support high-frequency response (such as filament heating), and improve the power stability and energy utilization of the electron beam system.

[0102] As the vapor deposition apparatus provided in this embodiment, its fourth structure includes:

[0103] Vacuum system 3 is connected to and cooperates with vapor deposition chamber 1 to adjust the vacuum level of vapor deposition chamber 1.

[0104] Preferably, in this embodiment, the vacuum system 3 consists of pipes, valves, a vacuum pump, and a vacuum gauge.

[0105] As the vapor deposition apparatus provided in this embodiment, its fifth structure includes:

[0106] like Figure 12 , Figure 15 As shown, the target deposition system 15 is used to provide a target to the vapor deposition chamber 1. The target is bombarded by an electron beam and evaporates to form a film on the surface of the engine blade.

[0107] The gas deposition chamber 1 is used to realize the surface deposition process of the engine blade. During the deposition operation, the target material in the gas deposition chamber 1 is heated by the electron beam bombardment to evaporate and form a film on the surface of the engine blade. The supply structure of the target material can adopt various schemes, which are not uniquely limited. In this embodiment, one of the feasible options is optimized and adopted: the gas deposition chamber 1 is provided with a target deposition port 104, which is controlled to be closed or opened by a deflection closed structure corresponding to the target deposition port 104; the target deposition system 15 includes a target sleeve assembly 1501 in communication with the target deposition port 104 and maintaining airtightness, a free end of the target sleeve assembly 1501 is connected and matched with a rotating device 1503, and the rotating device 1503 is used to drive the target material in the target sleeve assembly 1501 to rotate along the shaft; the target deposition system 15 further includes a feeding device 1502 matched with the target sleeve assembly 1501, and the feeding device 1502 is used to drive the target material to enter or exit the gas deposition chamber 1. When the above scheme is adopted, the target sleeve assembly 1501 at least includes an inner pipe for transmitting the target material. Due to the driving of the feeding device 1502, the target material is transmitted to the gas deposition chamber 1 through the inner pipe and rotates under the driving of the rotating device 1503, so that uniform heating and evaporation can be realized, and the uniformity of target consumption can be maintained. An outer pipe is further arranged outside the inner pipe, the outer pipe can adopt a telescopic bellows and is used to realize airtight sealing. When the target material is transmitted in the lifting process, the outer pipe can guarantee the airtightness of the gas deposition chamber 1 and maintain the vacuum degree in the gas deposition process.

[0108] In order to better solve the above technical problems and achieve the above purposes, the following structural improvements are made in the gas deposition equipment scheme of the embodiment:

[0109] As Figure 3 , Figure 5 , Figures 7-11As shown, during the engine blade deposition process, if the parts to be processed only enter and leave the vapor deposition chamber 1 from one loading position, there is a waiting time for pre-treatment and cooling after treatment. If the parts occupy the entry and exit position all the time, it will affect the efficiency of the whole treatment process. Therefore, optimization can be carried out to reduce or avoid waiting time, improve the use efficiency of the vapor deposition chamber 1, thereby improving the efficiency of the whole vapor deposition. This can be achieved by various methods, which are not uniquely limited. The embodiment is optimized and one of the feasible options is adopted: a double loading chamber system for loading and pre-treating engine blades is also included. The double loading chamber system includes two loading chambers 4 and is arranged on both sides of the vapor deposition chamber 1. The communication between the loading chamber 4 and the vapor deposition chamber 1 is provided with an isolation door 11 for controlling the opening and closing. The loading chamber 4 is connected with the vacuum system 3 and the inflation assembly, which is used to adjust the air pressure in the loading chamber 4. The in-situ radiation heating device is also arranged in the loading chamber 4 to preheat the engine blades. When the above scheme is adopted, the two loading chambers 4 are independent of each other and perform loading, pre-treatment, entering and leaving the vapor deposition chamber 1, and unloading of the parts to be processed. Since the isolation door 11 between the two loading chambers 4 and the vapor deposition chamber 1 forms airtight cooperation, when the vapor deposition operation in the airtight deposition chamber is completed, the parts return to the original chamber for subsequent treatment. The parts pre-treated in the other loading chamber 4 can be sent to the vapor deposition chamber 1, and the required vapor deposition treatment can be started quickly, avoiding the waiting process of occupying the vapor deposition chamber 1 for subsequent treatment, thereby improving the continuous working efficiency of the vapor deposition chamber 1.

[0110] Preferably, the loading chamber 4 is provided with a loading port 402 for opening and closing the loading chamber 4 to realize loading and unloading of the parts to be processed. The loading chamber 4 is also provided with a gas interface 403 for connecting the vacuum system 3 and the inflation assembly.

[0111] The in-situ radiation heating device can preheat the engine blade products to be processed to meet the requirements of subsequent vapor deposition treatment. The in-situ radiation heating device can adopt various schemes to achieve the purpose of heating the engine blades, and its structure is not uniquely limited. The embodiment is optimized and one of the feasible options is adopted: as shown in the figure, the in-situ radiation heating device includes a radiation heating device 401 and a heating chamber 402. The heating chamber 402 is arranged in the loading chamber 4 and is connected with the radiation heating device 401. The radiation heating device 401 is arranged on the side wall of the heating chamber 402 and is connected with the power supply system 5. The power supply system 5 is used to supply power to the radiation heating device 401 to realize the preheating of the engine blades in the loading chamber 4. Figure 17As shown, the in-situ radiation heating device includes two oppositely arranged heating units, which are driven by the heating driver 401 to approach or move away from each other; the heating unit includes a group of gate valves 404 connected with the heating driver 401 and synchronized to act, the gate valve 404 is connected with and synchronously drives the heating shell 405 to act, the heating shell 405 is provided with a heat preservation layer 406 and a heating element 407; when the two heating units approach, the gate valve 404 is folded to form a heating cavity, and the heating element 407 heats the engine blade in the heating cavity. When the above scheme is adopted, the gate valve 404 can reciprocate under the action of the heating driver 401 and drive the heating shell 405 to fold or open; when the engine blade is located at the preheating position, the heating shell 405 covers the engine blade after folding, and the internal heating element 407 works to heat up, thereby realizing the heating of the engine blade. The heat preservation layer 406 can make the heat stay in the in-situ radiation heating device more, and better heating effect is achieved.

[0112] Before the vapor deposition treatment, the engine blade is sent into the vapor deposition chamber 1, in order to improve the utilization rate of the vapor deposition chamber 1 and reduce the time of stopping deposition, the engine blades to be treated and the engine blades that have been treated can be separated by setting multiple matching structures 201, and orderly enter the vapor deposition chamber 1, so as to reduce the time of interrupting the work of the vapor deposition chamber 1, which can be realized by various schemes, and the structure is not uniquely limited, and the embodiment is optimized and one of the feasible choices is adopted: as shown in the figure Figure 3 、 Figure 7As shown, the engine blade loading device further comprises a double feeding system for driving the engine blade to move and adjust the posture, the double feeding system comprises two feeding devices 5 and is located outside the two loading chambers 4 respectively; the feeding device 5 comprises a linear displacement assembly for driving the support shaft 505 to move between the loading chamber 4 and the vapor deposition chamber 1, the support shaft 505 and the swing frame 509 at the front end of the support shaft 505 are driven to rotate coaxially by the revolution driver 504; the swing frame 509 is provided with a swing clamp 511 for connecting the engine blade, the support shaft 505 is provided with an inner driving shaft 508 and is driven by the rotation driver 503, the swing frame 509 is provided with a plurality of transmission shafts 510, the swing clamp 511 is rotationally matched with the transmission shaft 510, and when the rotation driver 503 is started, the swing clamp 511 is rotated by the inner driving shaft 508 and the transmission shaft 510. When the above scheme is adopted, the support shaft 505 drives the swing frame 509 to move forward, backward and overturn synchronously, and the revolution of the entire support shaft 505 and the swing frame 509 is realized after the revolution driver 504 is started. The revolution driver 504 can adopt a motor and is matched with the support shaft 505 through a transmission belt, a transmission gear and the like. At the same time, the rotation driver 503 is connected and matched with the inner driving shaft 508 and drives the inner driving shaft 508 to rotate, realizes the revolution of the inner driving shaft 508 in the support shaft 505, and the inner driving shaft 508 can be matched and driven with the transmission shaft 510 through a bevel gear and the like, the transmission shaft 510 is also matched and driven with the swing clamp 511 through a bevel gear and the like, and then the synchronous revolution of the swing clamp 511 is realized, and the engine blade revolves synchronously with the swing clamp 511 in this process.

[0113] Preferably, in the embodiment, the part of the support shaft 505 outside the loading chamber is sleeved with an airtight tube 506, the airtight tube 506 can adopt a bellows, is matched and connected with the loading chamber, can be compressed when the support shaft 505 enters the loading chamber, or can be elongated when the support shaft 505 exits the loading chamber, and the airtight tube 506 can keep the airtightness of the loading chamber through the matching. The loading chamber 4 is provided with an airtight connecting seat 507, and the airtight tube 506 is connected to the airtight connecting seat 507.

[0114] Preferably, the linear displacement assembly comprises a displacement track 501 and a displacement base 502 arranged on the track, and the support shaft 505 is connected to the displacement base 502 and moves synchronously and reciprocally.

[0115] In the process of carrying out the vapor deposition treatment, the temperature of some parts of the equipment rises obviously, and some areas even become high-temperature areas. In order to avoid causing the instability of the operation of the equipment or the damage of the adjacent structure caused by the excessively high temperature, the temperature inside the equipment needs to be controlled, especially the parts and areas working at high temperature. The temperature can be controlled in multiple ways. The embodiment is optimized and one of the feasible options is adopted: a cooling system 7 is further included, which is at least matched with the electron gun 2, the deposition chamber system, the double loading system and the double feeding system and used to provide cooling. When the above scheme is adopted, the electron gun 2 and the vapor deposition chamber 1 are both high-temperature areas. The electron gun 2 itself generates high temperature in the working process, and the vapor deposition chamber 1 also presents a high-temperature phenomenon. The double loading system is adjacent to the vapor deposition chamber 1 and needs to be pretreated by the in-situ radiation heating device, so it also generates temperature rise. The double feeding system is adjacent to the double loading system and also generates temperature rise due to heat conduction. According to the arrangement of the cooling system 7, the heat accumulation can be effectively reduced, and the temperature of the high-temperature area can be effectively controlled.

[0116] In the embodiment, a water-cooled jacket is arranged on the deposition chamber, which is matched with a water-cooling system to realize cooling and temperature reduction, so as to control the temperature of the deposition chamber.

[0117] The cooling requirements of different parts are different. According to the actual working parts, the corresponding settings can be made, and the overall temperature can be effectively controlled according to the structure adaptation. The structure is not uniquely limited. The embodiment is optimized and one of the feasible options is adopted: the cooling system 7 includes a water-cooled assembly matched with the electron gun 2. The water-cooled assembly at least covers the cathode area, the anode area and the secondary focusing area of the thermionic electron gun. At the same time, the water-cooled assembly at least covers the cathode area, the anode area, the gas ionization reaction area and the optical waveguide beam area of the field emission electron gun. When the above scheme is adopted, the water-cooled assembly cools the electron gun 2, so that the heat generated by the electron gun 2 in the opening and running process is effectively transferred, the performance of some parts is not weakened due to the temperature rise, the emission path of the electron beam is not affected, and the internal environment is not affected by the vapor generated by the bombardment of some parts by the electron beam. When the cooling is performed in this way, the emission power of the electron gun 2 can be effectively improved, for example, the emission power of the electron gun 2 can reach 250kW.

[0118] Preferably, when the hot emission electron gun is used, the temperature stability of the cathode can be accurately ensured by water cooling temperature control on the cathode emission area, so as to form a stable electron emission source. The probability of phenomena such as temperature abrupt change, beam current instability, discharge arc and the like caused by long-time power output is greatly reduced. By water cooling design on the anode part, the temperature of the anode is ensured to be in a relatively low state for a long time, so that the anode will not be melted by electron bombardment to cause a large amount of metal vapor excitation under any condition, thereby protecting the cleanliness inside the electron gun 2, greatly prolonging the maintenance period of the electron gun 2 and reducing the maintenance cost. By water cooling temperature control monitoring on the beam guide channel of the secondary focusing area, the beam guide channel is also ensured not to be melted by electron bombardment to cause a large amount of metal vapor excitation under any condition, thereby protecting the cleanliness inside the electron gun 2. And through real-time monitoring of the temperature, the position of the beam waist and the focusing state of the beam current can be intuitively fed back.

[0119] Preferably, when the field emission electron gun is used, the temperature stability of the cathode can be accurately ensured by water cooling temperature control on the cathode emission area, so as to form a stable electron emission source. The probability of phenomena such as temperature abrupt change, beam current instability, discharge arc and the like caused by long-time power output is greatly reduced. By water cooling temperature control on the hydrogen-oxygen gas mixed ionization area, the temperature of the ionization reaction area is ensured to be controllable, so that a large temperature loss is not caused, thereby ensuring that the ionization reaction is continuously and stably carried out.

[0120] By water cooling design on the anode part, the temperature of the anode is ensured to be in a relatively low state for a long time, so that the anode will not be melted by electron bombardment to cause a large amount of metal vapor excitation under any condition, thereby protecting the cleanliness inside the electron gun 2, greatly prolonging the maintenance period of the electron gun 2 and reducing the maintenance cost.

[0121] By water cooling temperature control monitoring on the beam guide channel of the secondary focusing area, the beam guide channel is also ensured not to be melted by electron bombardment to cause a large amount of metal vapor excitation under any condition, thereby protecting the cleanliness inside the electron gun 2.

[0122] The entire device is controlled to run by an automatic system when in operation, and can be realized by various schemes. In the embodiment, one of the feasible options is optimized and adopted, as shown in FIGS. 8 and 9. Figure 3 , Figure 7 As shown in FIGS. 8 and 9, the control system 9 is further included for monitoring and automatically controlling the start and stop of the deposition chamber system, the electron gun 2, the double loading system, the double feeding system and the cooling system 7. When the above scheme is adopted, the corresponding monitoring elements can be arranged to obtain the working parameters at each position, and the working parameters are sent to the control system 9. When the control system 9 obtains the data obtained by each monitoring element, the corresponding control instructions can be generated by data processing, so as to realize the automatic operation of the entire device.

[0123] Preferably, the control system 9 comprises a main control cabinet. The main control cabinet integrates a numerical control platform, centrally controls the vacuum system 3, the feeding system and the parameters of the electron gun 2, and realizes intelligent operation.

[0124] In this embodiment, a main support 12 is further included. The main support 12 is used to carry the deposition chamber, the vacuum system 3 and other core components, to guarantee the overall stability of the equipment through rigid frame design, and to optimize the anti-vibration performance through dynamic simulation.
