The robot performs subsequent assembly operations in the reserved space to complete the final assembly of the hinge. Each step is independent of each other and cooperates with each other to achieve automated assembly of the hinge, reduce manual intervention, and improve assembly efficiency and precision.

[0035] To sum up, the hinge jig and assembly process are equipped with a first jig, a second jig, a third jig and a fourth jig, and each jig has a clear division of labor, which realizes the process and automation of hinge assembly, avoids the inefficiency problem caused by the large variety and frequent replacement of jigs in the existing technology, greatly shortens the assembly time, and improves production efficiency; each jig realizes the precise positioning and clamping of hinge parts through the precise coordination of structures such as cylinders, inclined surfaces, and springs, reduces errors in the manual assembly process, ensures the accuracy and consistency of part installation, and thus improves the assembly accuracy of the hinge; utilizes the automation function of the jig to reduce dependence on manual labor, reduce labor costs, and also reduce rework caused by manual errors, further reducing production costs; each jig is independent of each other and works in coordination, which can realize batch assembly of hinges, meet the needs of large-scale production, and improve production flexibility and adaptability.

[0036] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
