[0002] Currently, in the field of on-board hydrogen system cylinder installation, the main method for installing hydrogen storage cylinders is manual assembly. This involves using a hoist or auxiliary lifting platform to manually install the cylinders into the hydrogen system frame.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] Embodiments of this utility model: such as Figures 1-13 As shown, a gas cylinder assembly system includes a feeding device 1, an angle correction device 2, a CCD detection device 3, a robotic arm 4, and a discharging device 5. The discharging device 5 is arranged in parallel with the feeding device 1. The robotic arm 4 is located between the discharging device 5 and the feeding device 1. The angle correction device 2 is located inside the tail end of the feeding device 1. The CCD detection device 3 is located at the tail end of the feeding device 1.

[0031] The feeding device 1 is used to transport the gas cylinder. When the gas cylinder is transported directly above the angle correction device 2, the transport stops. The angle correction device 2 lifts the gas cylinder. The CCD detection device 3 is used to detect whether the valve angle of the gas cylinder is at the set angle. If it is not at the set angle, it is adjusted by the angle correction device 2. After adjustment, the cylinder is picked up by the robotic arm 4 and transferred to the gas cylinder frame on the discharge device 5. After the staff manually fixes the gas cylinder, it is sent out by the discharge device 5.

[0032] This invention enables automatic conveying, automatic angle adjustment, and automatic assembly. Workers only need to complete the final fixing work, which not only improves work efficiency but also effectively ensures assembly quality.

[0033] Specifically, the feeding device 1 includes a first support frame 6, and at least two gas cylinder conveying devices are provided on the top of the first support frame 6. The multiple gas cylinder conveying devices are arranged at equal intervals and in parallel.

[0034] In this embodiment, the feeding device 1 is a cuboid frame structure. The top of the first support frame 6 is preferably equipped with two gas cylinder conveying devices. In this way, when one gas cylinder is being angled, the other gas cylinder has already reached the preset position. This can ensure that the angle correction device 2 and the CCD detection device 3 work continuously, thereby improving work efficiency.

[0035] Furthermore, the gas cylinder conveying device includes a rectangular support frame 7, roller assemblies 8, a first drive motor 9, and a transmission mechanism. Several roller assemblies 8 are equally spaced on the two long sides of the rectangular support frame 7. Any two adjacent roller assemblies 8 located on the same long side are connected by a first chain 10. The first drive motor 9 is located at the feeding end of the first support frame 6. The first drive motor 9 is connected to the first roller assembly 8 on the two long sides of the rectangular support frame 7 through the transmission mechanism.

[0036] The rectangular support frame 7 has a support plate 66 fixedly installed inside the feed end to support the first drive motor 9. The support plate 66 is arranged horizontally, and the first drive motor 9 is fixed on the top of the support plate 66.

[0037] The idler assembly 8 includes a conical idler 11, an idler shaft 12, a first bearing housing 13, and a double-chain sprocket 14. The idler shaft 12 is mounted on two first bearing housings 13, which are fixed to the top surface of the long side of the rectangular support frame 7 by a mounting plate. The conical idler 11 is fixed at one end of the idler shaft 12, and the double-chain sprocket 14 is fixed at the other end of the idler shaft 12.

[0038] The roller assemblies 8 on the two long sides of the rectangular support frame 7 are arranged opposite each other, and the tips of the conical rollers 11 on the two oppositely arranged roller assemblies 8 are facing each other and coaxially arranged. There is a certain gap between the two oppositely arranged roller assemblies 8, which is set to provide space for the angle correction device 2 to rise.

[0039] The transmission mechanism includes a drive shaft 15, a first sprocket 16, a second sprocket 17, and a third sprocket 18. The first sprocket 16, the second sprocket 17, and the third sprocket 18 are all fixed on the drive shaft 15. The two ends of the drive shaft 15 are mounted on the support plate 66 through the second bearing seats 19. A fourth sprocket 20 is fixed on the output shaft of the first drive motor 9. The fourth sprocket 20 is connected to the second sprocket 17 through the second chain 21. The first sprocket 16 is connected to the first idler assembly 8 on one of the long sides of the rectangular support frame 7 through the third chain 22. The third sprocket 18 is connected to the first idler assembly 8 on the other long side of the rectangular support frame 7 through the fourth chain 23.

[0040] The double-chain sprocket 14 is a sprocket with two chains connected by a connecting shaft, and the two chains and the connecting shaft are an integral structure. For ease of description, the chain closer to the first bearing housing 13 is called the first chain, and the other is called the second chain. The first chain on the first idler assembly 8 from the left, counting from the feed end, is connected to the first sprocket 16 via the third chain 22. The second chain is connected to the second chain on the second idler assembly 8 from the left via a first chain 10. The first chain on the second idler assembly 8 from the left is connected to the first chain on the third idler assembly 8 from the left via a first chain 10. All subsequent adjacent idler assemblies 8 are connected via the first chain 10 in this manner.

[0041] The first sprocket on the first idler assembly 8 from the right side of the feed end is connected to the third sprocket 18 via the fourth chain 23, and the subsequent connection method is the same as on the left side. When the first drive motor 9 is working, it drives the second sprocket 17 to rotate via the second chain 21, thereby rotating the drive shaft 15. The drive shaft 15 drives the first sprocket 16 and the third sprocket 18 to rotate synchronously, and then drives the first idler assembly 8 on the left and the first idler assembly 8 on the right to rotate via the third chain 22 and the fourth chain 23. Then, the first chain 10 drives all the idler assemblies 8 to rotate, thereby realizing the conveying of gas cylinders.

[0042] A limit bracket 67 is provided on the first support frame 6 near the CCD detection device 3. The limit bracket 67 has two specifications, the difference between the two specifications being the height. A proximity switch 68 is installed on the limit bracket 67. When the gas cylinder approaches the proximity switch 68, the first drive motor 9 stops running.

[0043] Furthermore, the angle correction device 2 includes a fourth linear slide rail 46, a fifth linear slide rail 47, a support platform 48, a first angle adjustment mechanism, and a second angle adjustment mechanism. The number of fourth linear slide rails 46 is at least four, and they are arranged perpendicular to the direction of movement of the gas cylinder. The support platform 48 is connected to the fourth linear slide rails 46 via a fourth slider. Two first cylinders 49 are arranged on the left side of the first support frame 6. The telescopic ends of both first cylinders 49 are fixedly connected to the bottom surface of the support platform 48 via connecting plates. A first angle adjustment mechanism is fixedly mounted on the top surface of the support platform 48 near the CCD detection device 3. Two fifth linear slide rails 47 are fixedly installed on the top surface by bolt assembly. The angle adjustment mechanism mounting base plate 50 is movably installed on the two fifth linear slide rails 47 by a fifth slider. The second angle adjustment mechanism is fixedly installed on the angle adjustment mechanism mounting base plate 50. A third rack 51 is also fixed on the support platform 48. The third rack 51 is located between the two fifth linear slide rails 47 and is parallel and straight to the fifth linear slide rails 47. A fourth drive motor 65 is provided on the angle adjustment mechanism mounting base plate 50. A third drive gear 52 is fixed on the output shaft of the fourth drive motor 65. The third drive gear 52 meshes with the third rack 51.

[0044] By pushing and pulling the first support platform 48 with the first cylinder 49, the first support platform 48, along with the first and second angle adjustment mechanisms, moves horizontally within the first support frame 6, thereby enabling the use of a set of angle correction devices 2 to adjust the angle of the gas cylinders on the two gas cylinder conveying devices, saving manufacturing costs.

[0045] The fifth linear slide rail 47 is arranged parallel to the conveying direction of the gas cylinder. By setting the fifth linear slide rail 47 and the angle adjustment mechanism mounting base plate 50, the position of the angle adjustment mechanism mounting base plate 50 can be changed by the cooperation of the third drive gear 52 and the third rack 51, thereby adjusting the position of the second angle adjustment mechanism, so that this product can be used for gas cylinders of different lengths.

[0046] The first and second angle adjustment mechanisms have identical structures, both including a second support base 53, a second cylinder 54, a fifth drive motor 55, a first rubber support roller 56, and a second rubber support roller 57. The second cylinder 54 is fixed to one side of the second support base 53, and two sixth linear slide rails 58 are fixed to the other side of the second support base 53. Both sixth linear slide rails 58 are vertically arranged. The motor support 59 is mounted on the two sixth linear slide rails 58 via four sixth sliders. The motor support 59 has a horizontal connecting plate 60 that extends from the top of the second support base 53 to the other side and connects to the cylinder rod end of the second cylinder 54. The top surface of the motor support 59 is fixed with... The system includes a fifth drive motor 55 and two support roller mounting rods 61 located on either side of the fifth drive motor 55. A first rubber support roller 56 is rotatably mounted on the upper end of one support roller mounting rod 61, and a second rubber support roller 57 is rotatably mounted on the upper end of the other support roller mounting rod 61. A first driven gear 62 is rotatably mounted on the middle of the support roller mounting rod 61 with the second rubber support roller 57. A second driven gear 63 is fixedly mounted on the shaft of the second rubber support roller 57. A fourth drive gear 64 is fixedly mounted on the output shaft of the fifth drive motor 55. The first driven gear 62 meshes with both the fourth drive gear 64 and the second driven gear 63.

[0047] The outer diameters of the first rubber support roller 56 and the second rubber support roller 57 are equal, and the highest points of the first rubber support roller 56 and the second rubber support roller 57 are located on the same horizontal plane. Their outer diameters are both larger than the outer diameter of the second driven gear 63. This ensures that the gas cylinder will not come into contact with the second driven gear 63 after being pressed on the second rubber support roller 57, thus preventing damage to the outer wall of the gas cylinder.

[0048] When the angle needs to be adjusted, the fifth drive motor 55 receives the working command. The fifth drive motor 55 is a servo motor. The fifth drive motor 55 rotates the corresponding angle according to the received working command, thereby causing the cylinder valve on the gas cylinder to rotate by the corresponding degree, thus completing the adjustment of the gas cylinder angle.

[0049] Furthermore, the CCD inspection device 3 includes a second support frame 24, a first electric linear guide rail 25, a second electric linear guide rail 26, and a CCD industrial camera 27. The first electric linear guide rail 25 is fixed to the top of the second support frame 24. The first electric linear guide rail 25 is horizontally arranged and its axis is perpendicular to the conveying direction of the gas cylinder. First linear slide rails 28 are fixed on both sides of the first electric linear guide rail 25. A first support plate 29 is slidably mounted on the two first linear slide rails 28 via two first sliders. The bottom of the first support plate 29 is also fixedly connected to the movable slider on the first electric linear guide rail 25. A first support base 30 is fixed to the top of the first support plate 29. The second electric linear guide rail 26 is fixed vertically on the first support base 30. A camera support 31 is fixed on the movable slider on the second electric linear guide rail 26. The CCD industrial camera 27 is mounted on the camera support 31. The CCD industrial camera 27 is a commercially available product and can be purchased directly.

[0050] Two support rods 32 are fixed on the camera support 31, and a ring-shaped fill light 33 is fixed at the other end of the two support rods 32. The ring-shaped fill light 33 is arranged coaxially with the CCD industrial camera 27.

[0051] It also includes a third support frame 34, on the top surface of which two parallel second linear slide rails 35 are fixed. The robotic arm mounting platform 36 is mounted on the two second linear slide rails 35 by a plurality of second sliders. In this embodiment, the number of second sliders is preferably six. A first rack 37 is fixed on the inner side of one of the second linear slide rails 35. A second drive motor 38 is mounted on the top of the robotic arm mounting platform 36. The output shaft of the second drive motor 38 is set downward and passes through the robotic arm mounting platform 36. A first drive gear 39 is fixed on the output shaft of the second drive motor 38. The first drive gear 39 meshes with the first rack 37. The robotic arm 4 is fixed on the robotic arm mounting platform 36.

[0052] The robotic arm 4 and the gas cylinder clamp on the robotic arm 4 (not shown in the figure) are commercially available products and are not within the scope of protection of this embodiment. Therefore, this embodiment will not elaborate on the specific structure and working principle of the robotic arm 4 and the gas cylinder clamp. The robotic arm 4 uses the gas cylinder clamp to pick up the gas cylinder, remove the gas cylinder from the feeding device 1 and place it on the discharging device 5.

[0053] The discharge device 5 includes a fourth support frame 40, a gas cylinder fixing frame support platform 41, and a third drive motor 42. The two long sides of the top surface of the fourth support frame 40 are respectively fixed with third linear slide rails 43. The gas cylinder fixing frame support platform 41 is mounted on the two third linear slide rails 43 by multiple third sliders. In this embodiment, the number of third sliders is also six. A second rack 44 is also fixed on the fourth support frame 40. The third drive motor 42 is fixed at the bottom of the gas cylinder fixing frame support platform 41. A second drive gear 45 is fixed on the output shaft of the third drive motor 42. The second drive gear 45 meshes with the second rack 44.

[0054] It should be noted that this product includes an electrical control cabinet 69, which contains a PLC programmable controller (not shown in the figure). The robotic arm 4, the first drive motor 9, the first electric linear guide 25, the second electric linear guide 26, the CCD industrial camera 27, the circular fill light 33, the second drive motor 38, the third drive motor 42, the solenoid valve on the first cylinder 49, the solenoid valve on the second cylinder 54, the fifth drive motor 55, the fourth drive motor 65, and the proximity switch 68 are all electrically connected to the PLC programmable controller.

[0055] The working principle of this utility model is as follows: The operator uses a crane 70, which is existing technology. The crane 70 is used to lift the gas cylinders from the buffer station onto the feeding device 1. The first support frame 6 has two gas cylinder conveying devices. For ease of description, the gas cylinder conveying device on the left is defined as the first gas cylinder conveying device, and the gas cylinder conveying device on the right is defined as the second gas cylinder conveying device. The PLC programmable controller controls the first drive motor 9 on the two gas cylinder conveying devices to work. When the first drive motor 9 works, it drives the second sprocket 17 to rotate through the fourth sprocket 20 and the second chain 21. The second sprocket 17 drives the transmission shaft 15 and the third sprocket 18 and the second bearing seat 19 on the transmission shaft 15 to rotate synchronously. Then, the third chain 22 and the fourth chain 23 drive the first idler roller assembly 8 at the feeding end to rotate. Then, the first chain 10 drives all the idler roller assemblies 8 to rotate, thereby realizing the conveying of the gas cylinders. When the gas cylinder moves to the other end of the first support frame 6, it approaches the proximity switch 68 on the limit bracket 67. After the proximity switch 68 detects the gas cylinder, it sends a signal to the PLC programmable controller. The PLC programmable controller controls the first drive motor 9 to stop working, and the gas cylinder stops moving.

[0056] The PLC programmable controller determines whether the gas cylinder is located on the first or second gas cylinder conveying device based on the signal received from the proximity switch 68. For example, if the gas cylinder is on the first gas cylinder conveying device, the PLC programmable controller controls the first cylinder 49 to retract, pulling the support platform 48 so that the support platform 48 moves directly below the first gas cylinder conveying device. At the same time, the PLC programmable controller controls the first electric linear guide 25 to work, moving the first support plate 29 to align with the first gas cylinder conveying device. Then, it controls the CCD industrial camera 27 to take a picture of the gas cylinder valve. During the picture taking, the ring-shaped supplementary light 33 is used for supplementary lighting. After taking the picture, the PLC programmable controller analyzes the picture and calculates the current angle of the valve. Then, it compares it with the preset angle in the program to calculate the angle and direction of rotation that the gas cylinder needs to rotate. If the gas cylinder does not need to rotate, the PLC programmable controller directly controls the robotic arm 4 to transfer the gas cylinder to the gas cylinder fixing frame 71 on the discharge device 5 through the gas cylinder clamp. If it is necessary to adjust the angle of the valve, the angle correction device 2 is controlled according to the rotation angle and direction. After receiving a command from the PLC programmable controller, the second cylinder 54 of the angle correction device 2 extends, the motor support 59 rises and passes between the two rows of roller assemblies 8 to contact the bottom of the gas cylinder. When the second cylinder 54 extends to a preset length, it stops extending. At this time, the gas cylinder is lifted by the first rubber support roller 56 and the second rubber support roller 57 on the first and second angle adjustment mechanisms, separating the gas cylinder from the conical roller 11. Then, the fifth drive motor 55 rotates according to the command from the PLC programmable controller. When the fifth drive motor 55 is working, it drives the first driven gear 62 to rotate through the fourth drive gear 64. The first driven gear 62 drives the second driven gear 63 to rotate, and the second rubber support roller 57 rotates synchronously with the second driven gear 63, causing the gas cylinder to rotate, thereby changing the angle of the cylinder valve. After the angle is adjusted, the second cylinder 54 retracts, the motor support 59 descends, and the gas cylinder falls back onto the feeding device 1 and contacts the conical roller 11. Then, the PLC programmable controller controls the robotic arm 4 to transfer the gas cylinder.

[0057] While the gas cylinders on the first gas cylinder conveying device are adjusting their angles, the gas cylinders on the second gas cylinder conveying device are simultaneously conveyed into position. The PLC programmable controller controls the first cylinder 49 to extend, and the support platform 48, carrying the first and second angle-adjusting mechanisms, moves to directly beneath the second gas cylinder conveying device. The detection and angle-adjusting processes will not be described in detail.

[0058] The gas cylinder fixing frame 71 is existing technology. The gas cylinder fixing frame 71 is fixed to the gas cylinder fixing frame support platform 41 by bolt assemblies. After the robotic arm 4 places the gas cylinder into the gas cylinder fixing frame 71, the operator uses tools to secure the gas cylinder firmly. After a preset interval, the PLC programmable controller controls the third drive motor 42 to work. Through the cooperation of the second drive gear 45 and the second rack 44, the gas cylinder fixing frame support platform 41 moves, transporting the assembled gas cylinder to the unloading station. The operator uses the crane 70 to unload it. After another preset interval, the PLC programmable controller controls the third drive motor 42 to work, causing the gas cylinder fixing frame support platform 41 to return to its initial position. The operator then installs a new gas cylinder fixing frame 71.
