Description

Technical Field

[0001] The present invention relates to the technical field of glue coating and press-fitting for the head valve seat of type IV hydrogen storage cylinders, and particularly to an automatic glue coating and press-fitting machine for the head valve seat of type IV hydrogen storage cylinders. Background Art

[0002] In the production process of the injection-molded inner liner of type IV hydrogen storage cylinders, the head and the valve seat are key elements that make up the core components of the hydrogen storage cylinder. The head needs to form a specific end shape during the injection molding stage. For this purpose, a part called the valve seat needs to be installed in cooperation to form a complete inner liner head structure. Washers and sealing rings need to be placed at different positions of the valve seat, and sealant is applied to the outer circles of these small parts to ensure the sealing effect. Before press-fitting the valve seat and the head, glue coating operations must also be carried out, and there are strict standard requirements for the amount of glue coated. Any product with broken glue or lack of glue should not flow into the subsequent production process. At the same time, the press-fitting force during the press-fitting process also needs to be strictly controlled. Excessive press-fitting force may cause product damage, while too small press-fitting force may cause the phenomenon of incomplete press-fitting.

[0003] Currently, the equipment for automatic glue coating and press-fitting of the head valve seat of type IV hydrogen storage cylinders in the domestic market is basically blank. At present, the installation of the inner washer and sealing ring in the valve seat completely depends on manual operation, and the application of the sealant is also completed manually, and it depends on visual inspection by humans to check for broken glue or leakage. After the valve seat parts are prepared, the head and the valve seat are manually placed in place, and the hydraulic device is manually operated for press-fitting operations. In this operation mode, it is impossible to accurately and intuitively monitor important parameters such as the press-fitting force.

[0004] Therefore, in view of the problems and deficiencies existing in the above-mentioned prior art, it is urgent to propose an automatic glue coating and press-fitting machine for the head valve seat of type IV hydrogen storage cylinders that can achieve automation and precise control, so as to improve production efficiency, ensure product quality, and reduce the dependence on manual operation.

[0047] This Type-IV hydrogen storage bottle automatic head-sealing valve seat gluing and pressing machine precisely controls the running positions of each component through the internal program of the PLC, and completes multiple sets of actions such as the automatic movement and rotation of the head, the automatic rotation of the valve seat, the automatic reverse discrimination and installation of the gasket, the automatic picking and installation of the sealing ring, the automatic gluing at the gluing position, the judgment of the glue amount and the automatic glue-breaking detection, the automatic pressing of the valve seat and the real-time feedback of the pressing force, and automatically stopping when the pressing force reaches the set value through the precise cooperation with various servo devices of the equipment itself. And a formula for different specifications of products is set in the control system. One formula corresponds to the position parameter information of each component in a set of products. Each type of product only needs to set the parameters once. The next time it is produced, the number can be directly called. Only a small number of self-made positioning parts need to be replaced to realize the valve seat gluing and pressing operations of multiple products. The production programs of all debugged products can be saved and called with one key, which greatly improves the flexible coverage of products and considerably reduces the cost expenditure of the client for products with different-sized head requirements. Moreover, it greatly improves the production efficiency and product qualification rate of gluing and pressing.
