Description

Technical Field

[0001] This application relates to the field of hydrogen storage bottle curing technology, and in particular to a fully automatic type IV hydrogen storage bottle curing device. Background Technology

[0002] Hydrogen storage cylinders, as an important energy storage device, have broad application prospects in fields such as new energy vehicles and aerospace. With the continuous development of hydrogen energy technology, Type IV hydrogen storage cylinders have attracted much attention due to their lightweight and high capacity characteristics.

[0003] In the existing curing process of Type IV hydrogen storage cylinders, the common practice is to manually load the cylinders onto a trolley and secure them using a manual clamping device. Then, workers manually or with the aid of other tools push the trolley containing the cylinders into the drying oven. Once in the designated position, the trolley brakes are manually engaged, and the shafts at both ends of the cylinders are secured using pre-installed clamping mechanisms. Finally, the rotary pressure connector is installed. While this manual operation method is simple and direct, it has many inconveniences in practical application. For example, manual operation can easily lead to inaccurate positioning and insecure fixing, thus affecting the curing effect and product quality. Furthermore, frequent manual intervention increases labor intensity and reduces production efficiency.

[0004] Existing manual operation methods for the curing of Type IV hydrogen storage cylinders have significant drawbacks, such as inaccurate positioning, insecure fixing, and cumbersome operation. These problems severely affect the production quality and efficiency of hydrogen storage cylinders. Therefore, there is an urgent need for a fully automated Type IV hydrogen storage cylinder curing equipment to reduce manual intervention, improve production efficiency, and ensure the consistency and stability of product quality.

[0005] To address the shortcomings of existing technologies, this application provides a fully automated Type IV hydrogen storage bottle curing equipment, which can reduce manual intervention and operation, improve the oven curing efficiency during mass production of hydrogen storage bottles, and achieve the goal of mass production of hydrogen storage bottles.

[0006] This application provides a fully automated Type IV hydrogen storage cylinder solidification device using the following technical solution:

[0007] A fully automated type IV hydrogen storage cylinder solidification device, comprising:

[0008] The product trolley transmission mechanism and the oven are provided.

[0014] This application further specifies that the product driving mechanism includes clamping rollers, a first cylinder, a reduction motor, and a second cylinder.

The output shaft of the second cylinder always drives the reduction motor to advance and engage with the support shaft of the hydrogen storage bottle.

[0015] By adopting the above technical solution, the spherical surface of the clamping roller can also support the support shaft of the hydrogen storage bottle, reduce the friction area, and avoid damaging the surface of the hydrogen storage bottle as much as possible. At the same time, it can make the hydrogen storage bottle rotate more smoothly.

[0019] By adopting the above technical solution, heat loss in the oven can be effectively prevented, and the temperature uniformity and stability of the oven heating the hydrogen storage bottle can be improved, thereby improving the curing effect of the hydrogen storage bottle and the product quality.

[0020] This application further includes the following configuration: a robotic arm is provided at the end of the product trolley transmission mechanism away from the product trolley, and the operating table is electrically connected to the robotic arm to invoke the action commands of the robotic arm and control it according to the action commands.

[0022] This application further provides that: a robotic arm guide rail is provided at the end of the product trolley transmission mechanism away from the product trolley guide rail; the end of the product trolley guide rail away from the oven abuts against the end of the product trolley transmission mechanism away from the robotic arm guide rail; the extension direction of the robotic arm guide rail is perpendicular to the extension direction of the product trolley guide rail; and the robotic arm is slidably connected to the top of the robotic arm guide rail.

[0023] By adopting the above technical solution, the robotic arm can move the robotic arm guide rail to the end of the product cart guide rail and place the gripped hydrogen storage bottle on the top of the product cart located at the top of the product cart guide rail, thereby realizing the automation of placing the hydrogen storage bottle onto the product cart.

[0024] This application further provides that: the top two ends of the product trolley are provided with supporting rollers for clamping and rotating in conjunction with the support shaft of the hydrogen storage cylinder.

[0039] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0040] refer to Figures 1 to 3 In this embodiment, a fully automatic Type IV hydrogen storage cylinder solidification device includes a product trolley transmission mechanism 6. A product trolley 4 is provided at one end of the product trolley transmission mechanism 6. A product trolley guide rail 5 is provided at the bottom of the product trolley 4. The product trolley 4 carries a hydrogen storage cylinder. The extension direction of the hydrogen storage cylinder is consistent with the extension direction of the product trolley guide rail 5. The product trolley transmission mechanism 6 can drive the product trolley 4 to move. The product trolley 4 slides on the top of the product trolley 4 guide rail.

[0041] A fully automatic type IV hydrogen storage cylinder curing equipment also includes an oven 9, which is fixed to the end of the product trolley guide rail 5 away from the product trolley transmission mechanism 6. The product trolley guide rail 5 extends into the oven 9, and the product trolley 4 can slide along the product trolley guide rail 5 into the oven 9. An oven lifting door 7 is slidably connected to the end of the oven 9 facing the product trolley transmission mechanism 6. The oven lifting door 7 can open or close the entrance / exit of the oven 9 facing the product trolley transmission mechanism 6 by lifting and lowering. A small oven door 10 is provided at the end of the product trolley 4 near the product trolley transmission mechanism 6. When the product trolley 4 enters the oven 9, a sensor electrically connected to the operating table 1 inside the oven 9 senses that the product trolley 4 has reached the corresponding position inside the oven 9. At this point, the bottom of the oven lifting door 7 abuts against the top of the small oven door 10, forming a good sealing environment. This ensures uniform distribution of temperature and pressure during the curing process and improves the production quality of the hydrogen storage cylinders.

[0042] A fully automatic Type IV hydrogen storage cylinder curing device also includes an operating console 1. The operating console 1 is equipped with an operation panel for inputting or calling action commands or programs by the operator. The operating console 1 is located at the end of the oven 9 furthest from the product trolley transmission mechanism 6. The operating console 1 is electrically connected to the product trolley transmission mechanism 6 and the oven 9 to call action commands for the product trolley 4 and the oven 9. Action commands include, but are not limited to, controlling the product trolley transmission mechanism 6 to drive the product trolley 4 into the oven 9 at a specified speed, controlling the oven lifting door 7 to raise or lower to open or close the oven 9's entrance and exit, and controlling the oven 9 to operate at a specified heating temperature and heating time. The action commands for the product trolley transmission mechanism 6 and the oven 9, and the control based on these action commands, are uniformly called by the operating console 1, ensuring coordinated operation between all components.

[0043] In this embodiment, the product trolley transmission mechanism 6 is controlled by the operating console 1 to raise the oven lifting door 7. The product trolley transmission mechanism 6 drives the product trolley 4 to move along the product trolley guide rail 5 into the oven 9, realizing the automation of the transportation process. After the hydrogen storage bottle loaded on the top of the product trolley 4 is sent into the oven 9 for curing, the oven lifting door 7 abuts against the oven door 10, sealing the oven 9. The program on the operating console 1 then controls the oven 9 to heat and cure the hydrogen storage bottle, reducing the manual input in the production process, improving the curing efficiency of the hydrogen storage bottle in the oven 9, and also improving the pass rate of mass-produced hydrogen storage bottles.

[0044] Furthermore, the extension direction of the oven 9 is consistent with the extension direction of the product trolley guide rail 5, so that the center of the front and rear end shafts of the hydrogen storage bottle mounted on the product trolley 4 at the top of the product trolley guide rail 5 can be on the same reference as the oven 9 and the product trolley guide rail 5, which helps to improve the qualification rate of hydrogen storage bottle production.

[0045] refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, the oven 9 has an opening on the side away from the product carriage transmission mechanism 6. A product driving mechanism 8 is provided on the side of the opening in the oven 9. The product driving mechanism 8 is used to clamp and rotate the support of the hydrogen storage bottle on the top of the product carriage 4. The support of the hydrogen storage bottle on the top of the product carriage 4 is clamped by the product driving mechanism 8 through the through opening. After fixing the relative position of the hydrogen storage bottle in the oven 9, the hydrogen storage bottle is rotated when the oven 9 is heated, thereby achieving uniform heating of the entire hydrogen storage bottle, improving the stability and safety of the product during the curing process, and thus improving the efficiency and product quality of mass production of hydrogen storage bottles.

[0046] Furthermore, the product drive mechanism 8 includes clamping rollers 80, a first cylinder, a reduction motor 81, and a second cylinder. The clamping rollers 80 are located at one end of the opening of the oven 9, and the two sets of clamping rollers 80 are vertically distributed. The output shaft of the first cylinder always drives the two sets of clamping rollers 80 to clamp the hydrogen storage bottle support shaft. When the product trolley 4 enters the oven 9, the support shaft of the hydrogen storage bottle at the top extends through the opening and is mounted on the top of the clamping rollers 80. The clamping rollers 80 clamp the support shaft of the hydrogen storage bottle under the output of the output shaft of the first cylinder.

[0047] The output shaft of the geared motor 81 faces the opening of the oven 9. The output shaft of the geared motor 81 has a slot for engaging the support shaft of the hydrogen storage bottle. The output shaft of the second cylinder always drives the geared motor 81 to move towards the support shaft of the hydrogen storage bottle. When the product trolley 4 enters the oven 9, the support shaft of the hydrogen storage bottle at the top extends through the opening and engages with the slot of the output shaft of the geared motor 81, thus completing the fixation of the hydrogen storage bottle by the geared motor 81 and fixing the hydrogen storage bottle in the relative position of the oven 9.

[0048] In this embodiment, the geared motor 81 engages with the support shaft of the hydrogen storage cylinder, and the clamping roller 80 further clamps the support shaft of the hydrogen storage cylinder. The spherical surface of the clamping roller 80 can strengthen the support shaft of the hydrogen storage cylinder, reducing the possibility of displacement or loosening of the hydrogen storage cylinder during heating, thus ensuring the uniformity and quality of curing. At the same time, the spherical design of the clamping roller 80 can reduce the friction area of ​​the support shaft of the hydrogen storage cylinder during rotation, making the rotation of the hydrogen storage cylinder smoother.

[0049] refer to Figure 1 , Figure 3 and Figure 6 In this embodiment, the bottom of the product trolley 4 is slidably connected to the top of the product trolley guide rail 5 via a gear and rack. The product trolley transmission mechanism 6 includes a drive motor. The output end of the drive motor always drives the gear and rack to move. The gear and rack drive the product trolley 4 to move smoothly and accurately along the product trolley guide rail 5, minimizing the risk of the product trolley 4 slipping during movement.

[0050] Furthermore, when the product cart 4 enters the oven 9, the sensor electrically connected to the control panel 1 detects that the product cart 4 has reached the corresponding position inside the oven 9. At this time, the oven door 10 and the oven lifting door 7 are on the same vertical plane, and the side of the oven door 10 facing the oven 9 abuts against the sealing strip 13. The control panel 1 then calls the action command to lower the oven lifting door 7, so that the bottom of the oven lifting door 7 abuts against the top of the oven door 10. Through the sealing strip 13, heat loss inside the oven 9 can be effectively prevented, thereby improving the temperature uniformity and stability of the heating and curing of the hydrogen storage bottle by the oven 9, and improving the curing effect and product quality of the hydrogen storage bottle.

[0051] Furthermore, a robotic arm 2 is installed at the end of the product trolley transmission mechanism 6 away from the product trolley 4. The operating table 1 is electrically connected to the robotic arm 2 to call the action instructions of the robotic arm 2 and control it according to the action instructions. The robotic arm 2 can pick up the gas canister that needs to be cured from the previous process and place it on the top of the product trolley 4, thereby realizing the automation of the gas canister grasping step.

[0052] Furthermore, a robotic arm guide rail 3 is installed at the end of the product cart transmission mechanism 6 away from the product cart guide rail 5. The end of the product cart guide rail 5 away from the oven 9 abuts against the end of the product cart transmission mechanism 6 away from the robotic arm guide rail 3. The extension direction of the robotic arm guide rail 3 is perpendicular to the extension direction of the product cart guide rail 5. The robotic arm 2 is slidably connected to the top of the robotic arm guide rail 3. The robotic arm 2 can move to any position along the extension length of the robotic arm guide rail 3, which is the position of the previous process, and then move to the end of the product cart guide rail 5 via the robotic arm guide rail 3 to place the gripped hydrogen storage bottle on top of the product cart 4 located at the top of the product cart guide rail 5. This flexibly automates the placement of the hydrogen storage bottle onto the product cart 4. Moreover, it can be combined with other processes to form an automated production line. Multiple curing devices can also be placed together and use the same robotic arm 2 to work, saving construction costs.

[0053] In addition, casters 12 are provided at the bottom of both ends of the product trolley 4. The casters 12 rotate and slide on the top of the product trolley guide rail 5, which not only makes the movement of the product trolley 4 smoother, but also increases the contact area between the product trolley 4 and the product trolley guide rail 5, thereby improving the stability of the product trolley 4 moving on the top of the product trolley guide rail 5.

[0054] refer to Figure 1 and Figure 2 In this embodiment, the top two ends of the product trolley 4 are provided with supporting rollers. The supporting rollers are used to clamp and rotate in conjunction with the support shaft of the hydrogen storage tank, which makes the product drive mechanism rotate the hydrogen storage tank more smoothly.

[0055] Furthermore, the bearings of the supporting roller 11 and the caster 12 are bearings with a maximum allowable operating temperature not less than the maximum heating temperature of the oven. Since the supporting roller 11 and the caster 12 need to enter the oven 9, the bearings of the roller and the caster 12 have high temperature resistance, which can achieve long-term stable operation, extend service life, and improve the safety of the hydrogen storage bottle solidification process.

[0056] The implementation principle of this application embodiment is as follows: The operator inputs action commands on the operating table 1, or calls the required program to call the action commands. After receiving the action command, the robotic arm 2 picks up the hydrogen storage bottle to be solidified from the previous process. The robotic arm 2 moves to the product trolley guide rail 5 via the robotic arm guide rail 3 and places the hydrogen storage bottle. After receiving the action command from the operating table 1, the lifting door of the oven 9 automatically opens. The product trolley 4 moves automatically along the product trolley guide rail 5 via the product trolley transmission mechanism 6 and automatically stops after reaching the designated position inside the oven 9.

[0057] After the product cart 4 reaches the designated position, the oven door 10 at one end of the product cart 4 presses against the sealing strip 13 of the oven 9, the oven 9 lifting door descends, and seals the oven 9 with the oven door 10. At the same time, the first cylinder of the product drive mechanism 8 drives the clamping roller 80 to clamp the product shaft, and the bayonet of the output shaft of the reduction motor 81 engages with the support shaft of the hydrogen storage bottle. Then, the second cylinder drives the reduction motor 81 to push and cooperate in the direction of the support shaft of the hydrogen storage bottle, so that the hydrogen storage bottle rotates according to the preset program of the operating table 1. At the same time, the oven 9 heats and solidifies the rotating hydrogen storage bottle.

[0058] After curing is completed, the second cylinder of the product drive mechanism 8 drives the reduction motor 81 to leave the support shaft, the first cylinder drives the clamping roller 80 to release the support shaft, and finally the product trolley 4 automatically exits the oven 9 through the product trolley transmission mechanism 6 and reaches the end of the product trolley guide rail 5 away from the oven 9, and enters the next process through the robot arm 2.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
