Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cells, and more particularly to the field of air compressor production lines, specifically to an installation device for a hydrogen fuel cell air compressor and a corresponding installation method thereof. Background Technology

[0002] A hydrogen fuel cell system is a device that directly converts the chemical energy stored in fuel and oxidant into electrical energy through electrochemical means. In a hydrogen fuel cell system, an air compressor is required to continuously deliver hydrogen, thereby accelerating the supply of hydrogen and increasing power.

[0003] Currently, the demand for hydrogen fuel cell systems is increasing, leading to a corresponding increase in the demand for air compressors. This also increases the demand for air compressor production lines, thus raising the requirements for air compressor installation efficiency. Developing reasonable and effective installation methods requires continuous research and experimentation. Currently, the production line installation methods for air compressors on the market, as well as some impeller and casing heating methods, all suffer from low efficiency.

[0004] Therefore, there is an urgent need to provide an improvement method to overcome the shortcomings of the current existing technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an installation device and corresponding installation method for an air compressor for a hydrogen fuel cell.

[0006] To achieve the above objectives, the present invention provides an installation device and corresponding installation method for a hydrogen fuel cell air compressor as follows: The main feature of this installation equipment for hydrogen fuel cell air compressors is that the equipment includes: The housing gripping module uses a high-precision gantry module combined with a vision system to automatically grip the air compressor housing on the pallet; The automatic heating module for the housing, through a linkage PLC system, automatically heats the air compressor housing and impeller, and monitors the temperature of the product during heating in real time, providing real-time feedback once the set temperature is reached. The rotor assembly module is connected to the automatic heating module of the housing. It uses mechanical modules and cylinders to position the heated air compressor housing and then install the rotor assembly. An impeller volute processing module, located in the middle of the device, is used for impeller volute clearance detection and volute assembly processing; and The double-speed chain conveyor mechanism is used to connect various workstations in series to generate the internal return line of the equipment.

[0007] Preferably, the housing gripping module includes a vision system module, a three-axis module gripper, a conveying mechanism, and a pallet assembly. The vision system module is positioned above the pallet assembly and is used to photograph and identify the materials placed on the pallet assembly. Simultaneously, it coordinates with the three-axis module gripper to sequentially grip the air compressor housing of the pallet assembly and place it on the conveying mechanism for transport.

[0008] Preferably, the pallet assembly adopts an upper and lower double pallet mechanism; the three-axis module gripper is equipped with a sensor switch for accurately gripping the air compressor housing.

[0009] Preferably, the automatic heating module for the housing includes a high-frequency heating module, an air compressor tray, and a short-speed chain module arranged sequentially from top to bottom. The short-speed chain module transports the air compressor tray to the heating station and lifts and positions the air compressor tray. The high-frequency heating module heats the air compressor housing on the air compressor tray. Once the set temperature is reached, the lifting mechanism on the short-speed chain module resets and transports the air compressor housing to the station of the rotor assembly module.

[0010] Preferably, the rotor assembly module includes a clamping mechanism, an air compressor tray, and a lifting and positioning mechanism arranged sequentially from top to bottom. The clamping mechanism and the lifting and positioning mechanism both use servo module mechanisms to achieve position lifting and lowering. The double-speed chain conveyor transports the air compressor tray carrying the air compressor housing to the current workstation and lifts and positions the air compressor tray. The lifting and positioning mechanism automatically positions the air compressor housing and the manually placed rotor. The clamping mechanism clamps the rotor and descends with the lifting and positioning mechanism. After the rotor is in place, it is transferred to the auxiliary workstation of the rotor assembly module for component assembly.

[0011] Preferably, the impeller and volute processing module includes an air compressor tray, an XZ axis module, and a 3D laser line scanning device. The XZ axis module is mounted on the 3D laser line scanning device, and the air compressor tray is positioned below the 3D laser line scanning device. When the air compressor housing flows to the current workstation via the double-speed chain conveyor mechanism, the lifting mechanism positions the air compressor tray and places the volute on the left side of the air compressor tray. The XZ axis module drives the 3D laser line scanning device to perform line scanning processing on the impeller and volute to complete 3D imaging, and the gap value is calculated by obtaining the difference between the contact point of the impeller and the volute and the reference surface.

[0012] Preferably, the impeller volute processing module further includes a lifting mechanism located at the bottom. The lifting mechanism controls the lifting of the impeller volute processing module by lifting the rotor, and detects the difference between the lifting rotor before and after lifting using a 3D laser line scanning device to obtain the axial movement of the lifting rotor.

[0013] Preferably, the device further includes: The impeller heating assembly module is used to sense the impeller at the current workstation through sensor components and automatically heat the impeller. An automatic gripping and conveying module for pressure-end volutes, connected to the impeller volute processing module, is used to precisely grip the pressure-end volutes placed on the tray at the current workstation. An automatic gripping and conveying module for volute end casings, connected to the impeller casing processing module, is used to precisely grip the volute end casings placed on the tray at the current workstation. The air-cooled water pipe assembly module is connected to the automatic gripping and conveying volute end housing module. The air-cooled water pipe fittings are manually installed onto the air compressor housing and locked in place. An airtight insulation performance testing module, connected to the aforementioned air-cooled water pipe assembly module, is used to test the airtightness and resistance performance of the air compressor through airtightness testing components; and The air compressor size detection module, connected to the airtightness and insulation performance detection module, is located at the rear of the installation equipment and is used to detect and mark the size information of the air compressor product at the current workstation through the camera assembly.

[0014] The method for installing a hydrogen fuel cell air compressor using the aforementioned installation equipment is characterized by the following steps: (a) The shell gripping module uses a high-precision gantry module combined with the vision system module to automatically grip the air compressor shell on the pallet: the vision system module automatically detects whether there is material at the current position and links with the shell gripping module to determine whether to grip it. (b) The speed-double chain conveyor mechanism connects each workstation in series to form the return line of the installation equipment; (c) The high-frequency heating module automatically heats the air compressor housing and impeller through the linkage PLC system, and monitors the temperature of the product during heating in real time, and provides real-time feedback after the set temperature is reached. (d) The rotor assembly module uses mechanical modules and cylinders to position the heated air compressor housing and then install the rotor assembly. (e) The installed impeller and volute are scanned by a 3D laser line scanning device fixed on a dual-axis linear module to complete 3D imaging. Then, the gap value is calculated by obtaining the difference between the contact point of the impeller and the volute end and the reference surface.

[0015] The installation equipment and corresponding installation method for hydrogen fuel cell air compressors using the present invention feature automatic feeding of the air compressor housing, pressure end volute, and scroll end volute, effectively saving space on the operating surface. Simultaneously, the air compressor housing and impeller are heated by high frequency, which not only facilitates operation but also significantly improves heating efficiency. Furthermore, the gap between the impeller and the air compressor housing is scanned using 3D laser, resulting in more accurate measurements. Its rational process and layout make the installation production line more efficient, significantly improving installation efficiency. Attached Figure Description

The vision system module 13 is disposed above the pallet assembly 16 and is used to photograph and identify the materials placed on the pallet assembly 16. At the same time, it is linked with the three-axis module gripper 14 to sequentially grip the air compressor housing of the pallet assembly 16 and place it on the conveying mechanism 15 for conveying.

[0035] In a preferred embodiment of the present invention, the pallet assembly 16 adopts an upper and lower double pallet mechanism; the three-axis module gripper 14 is equipped with a sensor switch for accurately gripping the air compressor housing.

The short-speed chain module 19 transports the air compressor tray 18 to the heating station and lifts and positions the air compressor tray 18. The high-frequency heating module 17 heats the air compressor housing on the air compressor tray 18. After the set temperature is reached, the lifting mechanism on the short-speed chain module 19 resets and transports the air compressor housing to the station of the rotor assembly module 5.

[0037] Please see Figure 4 As shown, in a preferred embodiment of the present invention, the rotor assembly module 5 includes a pressing mechanism 20, an air compressor tray 18, and a lifting and positioning mechanism 21 arranged sequentially from top to bottom. The pressing mechanism 20 and the lifting and positioning mechanism 21 both use servo module mechanisms to achieve position lifting and lowering. The double-speed chain conveyor 2 transports the air compressor tray 18 carrying the air compressor housing to the current workstation and lifts and positions the air compressor tray 18. The lifting and positioning mechanism 21 automatically positions the air compressor housing and the manually placed rotor. The pressing mechanism 20 presses the rotor and descends with the lifting and positioning mechanism 21. After the rotor is in place, it is transferred to the auxiliary workstation of the rotor assembly module 5 for component assembly.

[0038] Please see Figure 5 As shown, in a preferred embodiment of the present invention, the impeller volute processing module 8 includes an air compressor tray 18, an XZ axis module 22, and a 3D laser line scanning device 23. The XZ axis module 22 is mounted on the 3D laser line scanning device 23, and the air compressor tray 18 is positioned below the 3D laser line scanning device 23. When the air compressor housing flows to the current workstation via the double-speed chain conveyor 2, the lifting mechanism 24 positions the air compressor tray 18 and places the volute on the left side of the air compressor tray 18. The XZ axis module 22 drives the 3D laser line scanning device 23 to perform line scanning processing on the impeller and volute to complete 3D imaging, and calculates the gap value by obtaining the difference between the contact point of the impeller and the volute and the reference surface.

[0039] As a preferred embodiment of the present invention, the impeller volute processing module 8 further includes a lifting mechanism 24 disposed at the bottom. The lifting mechanism 24 achieves lifting control of the impeller volute processing module 8 by lifting the rotor, and detects the difference before and after lifting the rotor by the 3D laser line scanning device 23 to obtain the axial movement of the lifting rotor.

[0040] As a preferred embodiment of the present invention, the device further includes: a vortex end radial bearing housing 3, an impeller heating assembly module 6, an automatic gripping and conveying pressure end volute module 7, an automatic gripping and conveying vortex end volute module 9, an air-cooled water pipe assembly module 10, an airtight insulation performance testing module 11, and an air compressor size testing module 12.

[0041] The following section, in conjunction with the accompanying diagrams, will provide a more detailed explanation of the composition of each core module: Figure 1 The overall diagram of the production line includes, in sequence, a housing gripping module 1, a double-speed chain conveyor mechanism 2, a vortex end radial bearing seat 3, a housing automatic heating module 4, a rotor assembly module 5, an impeller heating assembly module 6, an automatic gripping and conveying pressure end volute module 7, an impeller volute processing module 8, an automatic gripping and conveying vortex end volute module 9, an air-cooled water pipe assembly module 10, an airtightness and insulation performance testing module 11, and an air compressor size testing module 12. The reasonable process assembly and appropriate accessories of this equipment make the production line operation simpler and more efficient.

[0042] Figure 2 The housing gripping module 1 shown mainly consists of a vision system module 13, a three-axis module gripper 14, a conveying mechanism 15, and a pallet assembly 16. The vision system module 13 takes pictures and identifies the materials on the pallet assembly 16, and then links the three-axis module gripper 14 to sequentially grip the air compressor housings on the pallet assembly 16, placing them on the conveying mechanism 15 for transport to the front end. The pallet assembly 16 uses a double-pallet mechanism, allowing for continuous loading without stopping the machine. The three-axis module gripper 14 is equipped with a proximity switch with a 30mm sensing distance, which can better sense the materials on the three-axis module gripper 14 and ensure accurate gripping of the housings. The automatic gripping and conveying pressure end volute module 7 and the automatic gripping and conveying vortex end volute module 9 use mechanisms that are basically similar to those of this workstation, only differing in the tooling they are equipped with.

[0043] Figure 3 The automatic heating module 4 shown mainly consists of a high-frequency heating module 17, an air compressor tray 18, and a short-speed chain module 19. The short-speed chain module 19 transports the air compressor tray 18 to the heating station and lifts and positions it. The high-frequency heating module 17 heats the shell on the air compressor tray 18 and monitors the temperature of the shell in real time. Once the temperature is reached, the lifting mechanism on the short-speed chain module 19 resets and transports it to the rotor assembly module 5. This module provides automatic heating on the line, with adjustable, precise, and convenient heating temperature, greatly improving the production cycle and making the production line process more rational.

[0044] Figure 4The core mechanism of rotor assembly module 5 is shown. This mechanism is mainly used for installing rotor and other components on the heated shell. It mainly consists of a pressing mechanism 20 at the top, an air compressor tray 18, and a lifting and positioning mechanism 21 at the bottom. The pressing mechanism 20 uses a servo module mechanism to raise and lower itself, so as to achieve precise control of its lifting distance and speed, and the parameters are adjustable. The lifting and positioning mechanism 21 at the bottom also uses a servo module mechanism to raise and lower itself, and is equipped with a shell positioning module. The double-speed chain conveyor 2 transports the air compressor tray 18 carrying the shell to this station and lifts and positions the air compressor tray 18. The lifting and positioning mechanism 21 automatically positions the shell and the manually placed rotor. The pressing mechanism 20 begins to press the rotor and descends together with the lifting and positioning mechanism 21 at the bottom. After the rotor is in place, all modules are automatically reset and transferred to the auxiliary station of rotor assembly module 5 for assembling bearing covers and other components and tightening screws.

[0045] Figure 5 The diagram shows the core mechanism of the impeller and volute processing module 8, mainly composed of a 3D laser line scanner 23, an XZ axis module 22, an air compressor tray 18, and a lower lifting mechanism 24. The air compressor housing moves to this station via the double-speed chain conveyor 2, then the air compressor tray 18 is lifted and positioned. The volute is placed on the left side of the air compressor tray 18. The XZ axis module 22, carrying the 3D laser line scanner 23, performs a line scan of the impeller and volute, creating a 3D image. The software selects the contact point between the impeller and the volute, and the same reference plane for both. The difference between the contact point and the reference plane is calculated, and the difference is subtracted to obtain the clearance value. This calculation process is automatically processed by the software system, directly yielding the result. The lower lifting mechanism 24 is responsible for lifting the rotor. The 3D laser line scanner 23 detects the difference in rotor movement before and after lifting, determining the rotor's axial movement.

[0046] This invention relates to a method for installing an air compressor for a hydrogen fuel cell using the aforementioned installation equipment, wherein the method includes the following steps: (a) The shell gripping module 1 uses a high-precision gantry module combined with the vision system module 13 to automatically grip the air compressor shell on the pallet: the vision system module 13 automatically detects whether there is material at the current position and links with the shell gripping module 1 to determine whether to grip it.

This station is divided into three parts: inspecting the size of the air compressor, marking the air compressor, and unloading the product. When the air compressor tray fixture 18 is transported to the size inspection station: vision camera I 50 performs size inspection and marking on the length and width of the air compressor product, while vision camera II 51 performs size inspection and marking on the height of the air compressor.

Furthermore, the gap between the impeller and the air compressor housing is scanned using 3D laser, resulting in more accurate measurements. Its rational process and layout make the installation production line more efficient, significantly improving installation efficiency.

[0058] In this specification, the invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations can be made without departing from the spirit and scope of the invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive.
