Higher energy efficiency means lower energy consumption, which is of great significance for improving the range of new energy vehicles. For example, new compressors are optimized in terms of structural design and motor control, which can compress refrigerants more efficiently and reduce energy loss.

[0004] Miniaturization and Lightweighting: New energy vehicles have high requirements for the spatial layout and weight of components, so the miniaturization and lightweighting of compressors is a future development trend. Manufacturers will adopt more advanced materials and design methods to reduce the size and weight of compressors, making them easier to install inside the vehicle, while also helping to reduce the overall energy consumption of the vehicle.

[0005] The compressor is mainly composed of a control unit, a drive motor, a fixed scroll, a movable scroll, bearings, a balance block, a wiring harness, intake and exhaust pipes, seals and other parts. Among them, the assembly of the double retaining ring of the wiring harness is a technical difficulty.

[0006] The traditional double retaining ring (circlip) assembly is manually assembled, which is inefficient, time-consuming and labor-intensive, and has poor assembly quality, low assembly qualification rate, poor precision, and easy damage to product parts, which brings risks to the manufacture of compressors and cannot meet existing assembly needs.

[0007] The Chinese patent with the publication date of November 03, 2020 and the publication number of CN111872646A discloses an invention patent entitled "A processing method for a stop ring of a scroll automobile air-conditioning compressor". The patent processing method includes the following steps: Step 1: Check whether the blank has defects such as lamination and cracks; Step 2: Use a punching die to punch the inner diameter and outer diameter of the stop ring; Step 3: Use a hot pressing mechanism to perform stamping and leveling on the plane of the stop ring; Step 4: Perform soft grinding on the positive and negative planes of the stop ring; Step 5: Perform medium frequency quenching on the stop ring, and after quenching, perform internal stress elimination at a high temperature of 220°C; Step 6: Perform thermal cycle cooling on the stop ring; Step 7: Perform chamfering on the stop ring; Step 8: Fine grinding the outer and inner diameters of the stop ring; Step 9: First perform mechanical fine grinding on the positive and negative planes of the stop ring; Step 10: Place the stop ring processed in step 9 in the air at room temperature for 6 hours to obtain a finished product. This patent greatly improves the precision of stop ring processing and extends the service life of the stop ring, while the present application is "automatic wiring harness double stop ring device and its working method", and the protection content of the two is obviously different.

The working method of the double stop ring device for automatic wiring harness installation in new energy vehicles according to claim 7, characterized in that: In step (S2), the working process of the transfer mechanism (3) is as follows: the picking mechanism (2) first releases the material, and then the anti-collapse plate (310) reaches the working position, pushing the cylinder assembly (32) to operate, so that the stop ring contraction mechanism (33) contracts the double stop rings, the anti-collapse plate (310) moves to the initial position through the anti-collapse plate moving cylinder (30), the unlocking cylinder (35) is unlocked, and the assembly mechanism (4) takes the material.
