[0020] The beneficial effects of the present invention are as follows:

[0021] Compared with the existing cable tie assembly, the present invention is designed specifically for the precision assembly of fixing cable ties, demonstrating the advantages of high automation and integration, significantly improving production efficiency and product quality. By integrating processes such as injection molding, automatic material taking, precise positioning, continuous conveying, and multi-station assembly, seamless connection of cable ties from raw materials to finished products is achieved, greatly shortening the production cycle and increasing the throughput of the overall production line. During the automated assembly process, each mechanism works in coordination to ensure the precise positioning and assembly of metal parts and caps. The precise hot riveting technology of the hot-melt mechanism effectively ensures the firm encapsulation of the cap and the assembly groove, reducing the defective rate caused by human factors and improving the stability and durability of the product. The high degree of automated operation reduces the dependence on labor, lowers labor costs, and at the same time avoids errors and injury risks that may be brought by manual operations, improving the safety of the working environment. Each mechanism is relatively independent and closely coordinated, facilitating flexible adjustment and expansion according to production requirements, such as adding inspection stations or adjusting the assembly sequence to adapt to the production of different specifications or types of cable ties. With the characteristics of high efficiency, stability, low cost, and intelligent management, the present invention provides strong technical support for the large-scale and high-quality production of fixing cable ties.

[0022] The raised design of the hot-melt strip in the present invention ensures sufficient contact and coverage with the welding table during the hot-melt process, effectively enhancing the firmness and sealing performance of the connection, and reducing the phenomena of missed connection and looseness during the assembly process. Secondly, the precise riveting operation of the hot-melt mechanism enables rapid and uniform hot-melting of the hot-melt strip on the welding table, not only improving the assembly efficiency but also ensuring the consistency of product quality. In addition, this structure optimizes the automated assembly process, reduces manual intervention, and lowers production costs and error rates.

[0023] The automatic assembly method for injection molded parts realizes full automation and precise control from injection molding to finished product blanking. Specifically, its technical effects are reflected in the following aspects:

[0024] Firstly, through the automated process of injection molding blanking and positioning transfer, manual intervention is effectively reduced, the production rhythm is increased, and it ensures the rapid, accurate blanking and orderly transfer of the cable tie body after injection molding, laying a solid foundation for subsequent assembly steps. Secondly, the precise assembly of the metal part and the cap, relying on the precise operation of the first and second assembly mechanisms, realizes the stable placement of the metal part in the assembly groove and the precise coverage of the cap, improving the assembly accuracy and consistency of the product and reducing the defective product rate. Moreover, the introduction of the hot-melt riveting technology uses the hot-melt mechanism to precisely rivet the hot-melt strip on the cap, not only enhancing the connection strength between the cap and the cable tie body but also ensuring the flatness of the surface after hot-melting through the design of the hot-melt groove, improving the appearance quality and durability of the product. In addition, the application of the laser marking technology completes the product identification immediately during the conveying process, not only improving the production efficiency but also ensuring the clarity and durability of the marking, facilitating product traceability and management. Finally, the automated processing of finished product blanking enables the prepared cable tie body to be quickly and neatly placed at the designated position, further enhancing the overall smoothness and production efficiency of the production line. It realizes the full automation and intelligentization of the production process, significantly improves the production efficiency and product quality, and reduces the production cost.
