Description

Apparatus and method for the automatic assembly of power control parts The present invention relates to an automatic assembly device and method for power control components. Power control components are installed in hybrid electric vehicles (HEVs) or electric vehicles (EVs) and are used to control power, such as by supplying or cutting off power to the battery. Among power control components, the EV relay is equipped with a fixed contact and a movable contact. When the fixed contact and the movable contact come into contact, the EV relay allows current to flow between the battery and other components. Conversely, when the fixed contact and the movable contact are separated, the EV relay blocks current flow between the battery and other components. Among such power control components, prior art for EV relays is Korean Published Patent Application No. 10-2022-0061725. Then, conventional technology manufactures an EV relay shaft including an EV relay movable contact and a shaft coupled thereto by assembling it through a process in which a worker manually places the shaft on a jig, assembles it in the order of a spring, movable contact, and washer, and rivets the top of the shaft. As such, conventional EV relay shafts are assembled manually by workers, which leads to high worker fatigue and significant variations in quality depending on the worker's skill level. In addition, since the assembly is done manually, defective products are produced with different heights on the left and right ends of the movable contacts, leading to a problem where current conduction failure occurs in the EV relay. In addition, conventional EV relay shafts have problems such as the riveting area bursting or the left and right ends of the movable contact failing to pass the detachment strength test or causing electrical failure because the pin forcibly flattens the surface as it descends from top to bottom when riveting the washer. To solve the problems associated with manufacturing products manually, active development is underway regarding manufacturing technology that uses a rotating turntable to manufacture products and checks for defects through vision inspection. An example of such prior art is Korean Registered Patent Publication No. 10-1492855. However, conventional technology performs vision inspection while the product is fixed to a jig installed on a rotating turntable. Since the turntable rotates continuously, when operated for a long time, friction causes separation between parts, resulting in an error that deviates from the measurement point (range). In addition, there is a problem of loss of time and cost because the measurement range of the camera unit must be continuously adjusted to resolve these issues.
