Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automatic assembly of rubber pipes, in particular to automatic installation and detection equipment for one-way valves, sponge blocks and rubber pipes. BACKGROUND

[0002] In modern automobile manufacturing, the performance of the hydraulic system directly affects the safety and reliability of the vehicle. As an important component of the hydraulic system, the assembly precision and efficiency of the rubber pipe are crucial to the performance of the overall system. The traditional assembly of the rubber pipe and the one-way valve mainly relies on manual operation, which usually requires multiple workers to work together, and the process is complicated and inefficient.

[0003] For manual assembly, the following problems exist: when manually holding the rubber pipe, the position deviation of the rubber pipe is easy to occur, which affects the assembly precision. During the process of installing the one-way valve into the rubber pipe, the depth of installation cannot be accurately controlled by manual operation, resulting in inaccurate insertion position of the one-way valve. With the rapid development of the automobile industry, the manual assembly method cannot meet the increasing production demand, resulting in low production efficiency.

[0004] Therefore, it is particularly necessary to develop a one-way valve assembly tool with high automation. There are also automatic assembly tools at present, and the related prior art such as Chinese patent application "Rubber pipe flow limiting valve assembly equipment", application number: CN201921719896.3, discloses a machine base, the surface of the machine base is provided with a rubber pipe positioning section profiling base, a rubber pipe flattening section base, a flow limiting valve profiling base and a valve pushing mechanism in sequence, the positioning section pressing mechanism is arranged above the rubber pipe positioning section profiling base, the rubber pipe clamping groove is arranged on the top surface of the rubber pipe flattening section base, and the rubber pipe flattening mechanism is arranged above the rubber pipe clamping groove, the recess matched with the flow limiting valve is arranged on the top surface of the flow limiting valve profiling base, and the flow limiting valve conveying mechanism is arranged above the recess, the flow limiting valve conveying mechanism conveys the flow limiting valve to the flow limiting valve profiling base, and the valve pushing mechanism pushes the flow limiting valve on the flow limiting valve profiling base into the rubber pipe.

[0005] The automatic assembly tool realizes the rapid and accurate butt joint of the valve body and the rubber pipe through mechanical means, which significantly improves the production efficiency. However, when the one-way valve and the rubber pipe are assembled, a sponge block also needs to be installed in the rubber pipe, and the existing assembly equipment cannot realize this. The above-mentioned patent application still relies on manual inspection of the placement of parts, which not only increases the work burden of the operator, but also may cause human errors.
