[0001] The invention relates to the technical field of type IV hydrogen storage bottle liner detection, and in particular to a type IV hydrogen storage bottle liner appearance inspection machine. Background Art

[0002] As the core component of hydrogen storage cylinders, the manufacturing quality of the injection-molded liner of the Type IV hydrogen storage bottle has a crucial impact on the overall performance of the hydrogen storage bottle. This liner is formed by injection molding into two parts, the head and the barrel, and then welded. In the subsequent manufacturing process, strict technical requirements are imposed on the length, straightness, diameter, and circular runout of the liner to ensure the safety and reliability of the hydrogen storage bottle.

[0003] However, in the current market, there is almost no automatic inspection equipment for the shape of the inner liner of the hydrogen storage bottle. Traditional inspection methods mainly rely on manual operation, such as manual measurement and manual recording using special calipers and other inspection tools. Although this method can meet basic inspection needs to a certain extent, it lacks effective inspection methods for parameters that cannot be directly measured manually, such as circular runout and straightness. Therefore, necessary inspection items for the size of the inner liner are often missing, which undoubtedly increases the potential risks of hydrogen storage bottles during use.

[0004] In view of the above problems, there is an urgent need for a device that can automatically and accurately detect the shape of the inner liner of a Type IV hydrogen storage bottle. This device needs to be adaptable to inner liner of various sizes and be able to accurately detect multiple parameters such as length, outer diameter, straightness and coaxiality. However, the existing technical conditions have not yet met this demand. Therefore, the present invention proposes a new type IV hydrogen storage bottle inner liner appearance inspection machine, which aims to solve this technical problem. Summary of the invention

[0043] The working process of the IV type hydrogen storage bottle liner appearance inspection machine mainly includes the following steps: Equipment initialization and preparation: Check and ensure that the whole machine frame is stable, and keep the equipment level by adjusting the bottom feet. Open the electric control cabinet, start the equipment power, and initialize the system. According to the specifications of the type IV hydrogen storage bottle liner to be tested, select or set the corresponding formula in the equipment control system. The formula contains the parameter information of each position in the equipment for the liner of this specification to ensure the accuracy of the test.

[0044] Liner loading and positioning: Place the Type IV hydrogen storage bottle liner to be tested on the lifting support assembly and ensure its stability. Start the translation servo motor and lifting servo motor of the lifting support assembly, and adjust the position and height of the lifting support assembly through the coordinated action of the ball screw assembly and the linear guide to adapt to the diameter and length of the liner. At the same time, start the translation servo motor of the rotary tightening assembly to move it to the top of the liner and tighten the liner bottle mouth through the cylinder. Then start the rotary servo motor to drive the liner to rotate through the cooperation of the tightening parts and the driven rotary support parts.

[0045] Axial detection: As the inner tank rotates, the axial detection component starts to work. The servo motor I of the axial detection component drives the synchronous belt, which drives the connector to slide on the linear guide component I of the axial detection component. The positive and negative screw groups on the inside of the connector are driven by the servo motor II of the axial detection component, so that the two sets of self-made C-type connecting plates move relative to or towards each other in the axial direction. The high-precision micrometer installed on the C-type connecting plate begins to measure the parameters such as the diameter, coaxiality, straightness and circular runout of the inner tank. The measurement results are fed back to the equipment control center in real time.

[0046] Radial detection: The radial detection component drives the synchronous belt through the servo motor to drive the grating head to move horizontally on the crossbeam of the radial detection component. The grating scale under the grating head cooperates with the grating head to accurately measure the moving distance of the grating head. At the same time, the self-made stopper on the linear guide assembly cooperates with the zero calibration block to ensure the accuracy of the measurement. Radial detection is mainly used to further verify the parameters such as the diameter and circular runout of the inner liner.

[0047] Data processing and result output: The equipment control center receives and processes the measurement data from the axial detection component and the radial detection component. According to the preset qualification standard, it determines whether the inner liner is qualified. The test results are fed back to the operator in real time, and the test records are saved in the computer that comes with the equipment. The operator can take corresponding measures based on the test results, such as passing the qualified inner liner to the next process and reworking or scrapping the unqualified inner liner.

[0048] Equipment reset and preparation for next test: After completing a test, the equipment automatically resets to the initial state. The operator can unload the tested liner and prepare the next liner to be tested. If you need to test liner of different specifications, just select the corresponding formula in the equipment control system.

[0049] The type IV hydrogen storage bottle liner appearance inspection machine accurately controls the travel position of the grating ruler and high-precision micrometer through the PLC internal program, and cooperates with multiple groups of servo drive mechanisms to realize multiple functions such as length detection, outer diameter detection, straightness detection and coaxiality detection applicable to a variety of type IV bottle liners. The detection results are fed back to the equipment control center in real time, so that humans can promptly understand whether the liner inspection in the equipment is qualified or not. When the unqualified or qualified parameters of the product need to be uniformly searched in the future, they can be searched from the computer built into the equipment. In addition, formulas for products of different specifications are set in the control system. One formula corresponds to the parameter information of each position in the equipment for a set of products. Each product only needs to set the parameters once, and the number can be directly called during the next production, which greatly improves the efficiency and effectiveness of the liner appearance inspection.

The lifting servo motor (3-1) for translating the lifting unit drives the lifting ball screw assembly (3-2) of the lifting unit to drive the slider II (3-8) on the rotary clamping unit linear guide rail (2-11) to translate.

9. A type IV hydrogen storage bottle liner appearance inspection machine as claimed in claim 1, characterized in that: Two axial detection component columns (4-1) are fixed in parallel on the whole machine frame (1); an axial detection component crossbeam (4-12) is fixedly arranged between the two axial detection component columns (4-1); a connecting piece (4-5) movable along the length direction of the inner liner is arranged on the axial detection component crossbeam (4-12); and a high-precision micrometer is installed on the connecting piece (4-5).

10. A type IV hydrogen storage bottle liner appearance inspection machine as claimed in claim 9, characterized in that: A radial detection component crossbeam (5-4) is fixedly arranged between two axial detection component columns (4-1); a grating reader (5-7) of a grating ruler that can move along the length direction of the inner liner is arranged on the radial detection component crossbeam (5-4); and a grating scale (5-8) that cooperates with the grating reader (5-7) is arranged on the radial detection component crossbeam (5-4).
