[0055] The working process of the type IV hydrogen storage bottle inner container appearance inspection machine mainly includes the following steps:

[0056] Device initialization and preparation: Check and ensure that the whole machine frame is stable, and keep the device level by adjusting the bottom foot. Open the electrical control cabinet, start the device power supply, and perform system initialization. According to the specification of the Type IV hydrogen storage bottle liner to be detected, select or set the corresponding formula in the device control system. The formula contains the position parameter information of each position in the device for this specification liner, to ensure the accuracy of the detection.

[0057] Liner loading and positioning: Place the Type IV hydrogen storage bottle liner to be detected on the lifting support assembly and ensure its stability. Start the translation servo motor and the lifting servo motor of the lifting support assembly, adjust the position and height of the lifting support assembly through the cooperation of the ball screw assembly and the linear guide rail, to adapt to the diameter and length of the liner. At the same time, start the translation servo motor of the rotary clamping assembly, move it above the liner, and clamp the liner bottle opening through the air cylinder. Then start the rotary servo motor, drive the liner to rotate through the cooperation of the clamping parts and the driven rotary support parts.

[0058] Axial detection: While the liner is rotating, the axial detection assembly starts to work. The axial detection assembly servo motor I drives the synchronous belt, which drives the connecting piece to slide on the axial detection assembly linear guide rail assembly I. The positive and negative screw rod group inside the connecting piece is driven by the axial detection assembly servo motor II, which makes the two groups of self-made C-shaped connecting plates move in opposite directions or towards each other in the axial direction. The high-precision micrometer installed on the C-shaped connecting plate starts to measure the diameter, coaxiality, straightness and roundness of the liner. The measurement results are fed back to the device control center in real time.

[0059] Radial detection: The radial detection assembly drives the synchronous belt through the servo motor, which drives the grating reader to move horizontally on the radial detection assembly beam. The grating scale below the grating reader cooperates with the grating reader to accurately measure the movement distance of the grating reader. At the same time, the self-made stop ruler on the linear guide rail assembly cooperates with the zero calibration stop block to ensure the accuracy of the measurement. Radial detection is mainly used to further verify the diameter and roundness of the liner.

[0060] Data processing and result output: The device control center receives and processes the measurement data from the axial detection assembly and the radial detection assembly. According to the preset qualification standard, it judges whether the liner is qualified or not. The detection results are fed back to the operator in real time, and the detection records are saved in the computer inside the device. The operator can take corresponding measures according to the detection results, such as qualified liners entering the next process, unqualified liners being reworked or scrapped.

[0061] Device reset and preparation for next detection: After completing a detection, the device automatically resets to the initial state. The operator can unload the detected liner and prepare the next liner to be detected. If different specifications of liners need to be detected, only need to select the corresponding formula in the device control system.

[0062] The IV type hydrogen storage bottle liner appearance inspection machine accurately controls the running position of the grating ruler and high-precision micrometer through the PLC internal program, and cooperates with multiple groups of servo driving mechanisms to realize multiple functions such as length detection, outer diameter detection, straightness detection and coaxiality detection of various IV type bottle liners, and the detection results are fed back to the equipment control center in real time, so that the personnel can know whether the liner detection is qualified or not in time. Also, when it is necessary to find the unqualified or qualified parameters of the product in the subsequent, the computer in the device can be used to find, and the control system is provided with formulas for different specifications of products. One formula corresponds to the position parameter information of each product in the device. Each product only needs to set the parameters once, and the next time the production is directly called by the number, which greatly improves the efficiency and effectiveness of the liner appearance inspection.
