Description

Automatic wiring harness double stop ring device and its working method in new energy vehicles Technical Field

[0001] This invention relates to a device and its working method, and more particularly to an automatic wiring harness double stop ring device and its working method in new energy vehicles, which belongs to the technical field of new energy vehicle compressor equipment. Background Technology

[0002] New energy vehicle compressors are used in air conditioning systems for cooling and heating. As the market penetration rate of new energy vehicles continues to increase, the demand for compressors, as a key component, is becoming increasingly prominent.

[0003] Energy Efficiency Improvement: With continuous technological research and innovation, the energy efficiency of compressors in new energy vehicles will continue to improve. Higher energy efficiency means lower energy consumption, which is of great significance for increasing the driving range of new energy vehicles. For example, new compressors have been optimized in terms of structural design and motor control, enabling them to compress refrigerant more efficiently and reduce energy loss.

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

[0005] The compressor is mainly composed of several parts, including control unit, drive motor, fixed scroll, moving scroll, bearing, balance block, wiring harness, intake and exhaust pipes, and seals. Among them, the assembly of double stop rings in the wiring harness is a difficult process.

[0006] Traditional double retaining ring (circlip) assembly is done manually, which is inefficient, time-consuming and labor-intensive, and results in poor assembly quality, low pass rate, poor precision, and easy damage to product parts. This poses a risk to compressor manufacturing and cannot meet current assembly requirements.

[0007] Chinese patent CN111872646A, published on November 3, 2020, discloses an invention patent entitled "A Processing Method for a Stop Ring of a Scroll-Type Automotive Air Conditioning Compressor." The processing method includes the following steps: Step 1: Inspect the blank for defects such as lamination and cracks; Step 2: Use a punching die to punch the inner and outer diameters of the stop ring; Step 3: Use a hot pressing mechanism to punch and level the surface of the stop ring; Step 4: Perform soft grinding on both sides of the stop ring; Step 5: Perform medium-frequency quenching on the stop ring, followed by stress relief treatment at 220℃; Step 6: Perform thermal cycling cooling on the stop ring; Step 7: Perform chamfering on the stop ring; Step 8: Perform precision grinding on the outer and inner diameters of the stop ring; Step 9: Perform mechanical precision grinding on both sides of the stop ring; Step 10: Place the stop ring treated in Step 9 in air at room temperature for 6 hours to obtain the finished product. This patent greatly improves the precision of the stop ring processing and extends the service life of the stop ring, while this application is for "automatic wire harness double stop ring device and its working method". The content of protection of the two is obviously different. Summary of the Invention

When the feeding cylinder's action is balanced with the force of spring two, the picking cylinder is vented, enabling the picking of the stop ring. Spring one is positioned on the upper part of the picking mechanism, allowing it to float. The transfer mechanism includes an anti-collision plate moving cylinder, a transfer fixing plate, a push cylinder assembly, a stop ring retraction mechanism, a floating mechanism, a transfer plate, and an anti-collision plate. The floating mechanism is connected to the transfer fixing plate via the transfer plate. The stop ring retraction mechanism is mounted on the floating mechanism.

[0014] Preferably, the distance between the picking end of the picking mechanism and the picking end of the assembly mechanism is matched with the discharge port position of the discharge mechanism and the transfer port position of the transfer mechanism.

[0015] The present invention also provides a method for operating an automatic wire harness double stop ring device, characterized by the following specific steps:

[0016] (S1) The stop ring is manually fed into the hopper of the discharge mechanism. The discharge mechanism discharges the material. The pick-and-place position switching mechanism drives the servo module to move, causing the pickup mechanism and assembly mechanism to work together. The servo module drives the assembly mechanism and pickup mechanism to move up and down. The pickup mechanism picks up the stop ring. The assembly mechanism picks up the stop ring of the stop ring retraction mechanism in the transfer mechanism. The pick-and-place position switching mechanism and servo module move. Then the pickup mechanism and assembly mechanism move together. The servo module drives the assembly mechanism and pickup mechanism to move up and down. The assembly mechanism reaches the product positioning station position, and the pickup mechanism reaches the transfer mechanism position.

[0017] (S2) When the feeding cylinder and the spring in the picking mechanism are in balance, the picking cylinder is ventilated to realize the picking of the material from the stop ring to the transfer mechanism.

[0018] (S3) The working process of the assembly mechanism: Under the action of the external servo motor, the assembly mechanism moves downward; after the assembly head contacts the product, the O-ring sensor detects a signal and continues to move downward until the foreign object sensor detects a signal, the unlocking cylinder unlocks, the variable diameter cylinder finishes working, the assembly mechanism moves upward as a whole, and then moves downward after leaving the product position, the stop ring sensor detects a signal, confirms the double stop ring, and confirms that the stop ring is assembled in place;

[0019] (S4) Servo module reset, loading and unloading position switching mechanism reset, remove the double stop ring after assembly, and end the whole action.

[0020] Preferably, in step (S2) of the present invention, the working process of the transfer mechanism is as follows: the picking mechanism first puts out the material, then the anti-collapse plate reaches the working position, pushes the cylinder assembly to move, so that the stop ring contraction mechanism contracts the double stop ring, the anti-collapse plate moves to the initial position through the anti-collapse plate moving cylinder, the unlocking cylinder unlocks, and the assembly mechanism picks up the material.

[0021] Compared with the prior art, the present invention has the following advantages and effects: (1) The overall structure design is safe and reasonable, stable and reliable, and has good precision. It can realize the simultaneous installation of double stop rings, with high assembly efficiency and can guarantee product quality; (2) The spacing between the picking mechanism, the assembly mechanism, the material discharge mechanism, the transfer mechanism and the product positioning station and the transfer mechanism are equal, so that material picking and assembly are realized in the same position, which improves work efficiency; (3) Wire harness double stop ring picking mechanism: The lower tooling is designed with a piston mechanism, and the upper tooling is equipped with a ventilation pipe and a stop ring guide mechanism. After the lower tooling piston is in place, the stop ring is effectively pushed into the upper tooling. When the upper tooling is lifted, the piston mechanism of the lower tooling is automatically reset through the internal spring mechanism. This mechanism has a simpler structure and effectively improves the stability of the stop ring pickup. (4) Wiring harness double stop ring assembly mechanism: The structure is equipped with a combination of servo, cylinder and spring drive to enable the two assembly tools to automatically open and reset, effectively solving the problem of the stop ring assembly position eccentricity. After the two assembly tools are opened into place, the tooling is introduced to bear the force so that the two stop rings are assembled into the target assembly position at the same time. The assembly tool is equipped with a sensor to confirm that the stop ring has been correctly installed. This mechanism has a simpler structure and effectively improves the stability of the stop ring assembly. Attached Figure Description
