Through the cooperation of the feeding assembly, the feeding mechanism and the clamping mechanism, the whole process automation from insulator feeding, posture adjustment, clamping positioning, drilling processing to chip cleaning, defect detection and finished product discharge is realized. The existing technology relies on manual feeding, turnover detection and manual discharge, which has the problems of complicated operation and low efficiency. In the present application, the feeding assembly realizes single quantitative automatic feeding through the cooperation of the servo cylinder, the partition plate and the sensor, the feeding mechanism automatically completes the lifting of the insulator, the horizontal-vertical posture conversion through the transmission of the first motor, the synchronous belt and the second motor, and the clamping mechanism automatically realizes clamping, circumferential cleaning and defect detection through the driving of the second electric push rod and the fourth motor, without manual intervention throughout, effectively reducing labor costs and adapting to the batch production needs of new energy automobile insulators.

[0016] 2. The feeding mechanism ensures the accurate alignment of the vacuum chuck and the insulator through the visual positioning of the first industrial camera; the guide rod of the lifting assembly limits the movement trajectory of the second C-shaped plate to avoid transportation deviation; and the annular plate of the clamping mechanism forms a circular clamping structure after merging, which realizes the stable positioning of the insulator at two points up and down with the auxiliary limiting of the limiting roller and the sliding rod. The existing technology often causes drilling position deviation due to positioning error, affecting the assembly and adaptation of the electric vehicle connector terminal; the multiple positioning design of the present application significantly reduces the drilling position precision error, which meets the assembly requirements of the electric connector insulating part; the vacuum chuck flexibly fixes the insulator through adsorption force, and the rubber strip on the inner wall of the annular plate buffers the clamping force to avoid the damage of the high molecular insulating surface layer caused by rigid clamping in the existing technology; after drilling, the jet head accurately cleans the debris to avoid the influence of debris adhesion on the insulating performance, and the second industrial camera comprehensively detects the drilling burr and other defects, and the flexible cleaning brush performs chamfering treatment on the hole angle to optimize the edge roughness. This design solves the problems of easy damage of the insulating layer of the insulator and undetected drilling defects in the existing technology, ensuring that the product meets the insulating reliability of the electric vehicle energy storage / power supply circuit.

[0017] 3. The first electric telescopic rod can extend and adjust the spacing of the vacuum suction cups. The combined structure of the annular plate can adapt to cylindrical insulators of different diameters. Compared with the limitations of single-size adaptation in the prior art, this invention can meet the processing needs of insulators of various specifications of new energy vehicle connectors and reduce equipment replacement costs. The equipment adopts a modular design, with the feeding mechanism, clamping mechanism, and feeding components being independent and the transmission structure being clear.
