[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1) Improve assembly efficiency

[0020] Automated process: This static spring assembly machine achieves a fully automated process from static spring feeding, handling, transportation, flipping to screwing and inserting into the relay. The flexible feeding mechanism flattens the static spring to facilitate grabbing and transportation. The static spring transport mechanism transports the static spring to the designated location. The static spring handling robot, switching mechanism and static spring assembly manipulator work together to complete a series of complex operations without the need for human intervention, greatly improving assembly efficiency. Multi-station parallel: Static spring devices are arranged in an array on one side of the tooling carrier, and multiple static springs can carry out different stages of assembly operations at the same time. For example, multiple static springs can be flattened at the same time in the flexible feeding mechanism, and can also be carried at the same time in the static spring transport mechanism. This multi-station parallel working mode further speeds up the overall assembly speed and meets the needs of large-scale production.

[0021] 2) Ensure assembly accuracy

[0022] Precise Grasping and Positioning: The static spring handling robot's suction assembly is ingeniously designed. The accordion suction cup on the suction block generates suction through vents, firmly securing the static spring. The contoured positioning shoulder ensures the spring's precise positioning during the suction process. A switching mechanism, through the coordinated operation of the lifting cylinder, horizontal switching cylinder, tilting cylinder, and the first static spring gripping finger cylinder, precisely grasps and flips the static spring, ensuring its precise positioning between different steps. The static spring assembly robot's screw lifting assembly, twisting and swinging cylinder, and assembly finger cylinder precisely insert the static spring into the relay, ensuring assembly accuracy. The transport and positioning assembly: The circular static spring transport track within the static spring transport mechanism works in conjunction with the pusher and positioning assemblies to precisely transport the static spring to the designated location and position it during transport to prevent it from shifting. This provides a precise positioning foundation for subsequent assembly operations, further ensuring assembly accuracy.

[0023] 3) Improve product quality

[0024] Good consistency: The automated assembly process avoids the inconsistencies of manual operation. Each static spring undergoes the same precise operation, ensuring consistent assembly quality for each product, reducing quality variations caused by human factors, and improving the overall quality stability of the product. Reduced damage: Throughout the assembly process, the static springs are operated through specially designed suction, handling, and assembly mechanisms, avoiding damage that may be caused by manual operation. For example, the flexible suction and precise handling of the accordion suction cups reduce deformation and wear of the static springs during assembly, ensuring the integrity and performance of the static springs, and thus improving the quality of the final product.

[0025] 4) Enhance equipment versatility and flexibility

[0026] Modular Design: Each component of the assembly machine, such as the static spring handling robot, switching mechanism, and static spring assembly manipulator, possesses a degree of independence and versatility. Based on different production requirements, the various modules can be adjusted and combined to accommodate the assembly of relay static springs of varying specifications and models, enhancing the equipment's versatility. Scalability: In addition to the core static spring assembly device, the machine is also equipped with a feeding device, a pressing device, a detection device, and a discharge device. These devices can be expanded and upgraded according to production needs, such as adding different types of feeding devices or detection devices to meet different production process requirements, enhancing the equipment's flexibility and scalability.

[0027] 5) Reduce labor intensity and costs

[0028] Labor Reduction: The fully automated assembly process significantly reduces reliance on manual labor. Workers no longer need to perform arduous manual assembly operations, reducing labor intensity and minimizing productivity declines and quality issues caused by fatigue. Cost Savings: Automated production improves production efficiency and reduces labor costs. Furthermore, the precise assembly process reduces scrap and rework rates, reducing raw material waste and production costs. Furthermore, the versatility and scalability of the equipment lowers the cost of repurchasing equipment for product upgrades. BRIEF DESCRIPTION OF THE DRAWINGS
