Description

Technical Field

[0001] This utility model relates to the technical field of circuit board washing devices, and in particular to a circuit board washing device for integrated optoelectronic devices. Background Technology

[0002] Water washing of circuit boards mainly utilizes the dissolving and rinsing properties of water. Under proper operation, water can effectively dissolve and remove dirt, grease, and other impurities from the surface of the circuit board.

[0003] In the prior art, a search revealed a Chinese patent entitled "A Washing Device for Circuit Boards in the Manufacturing of Integrated Optoelectronic Devices," application number "202420169842.9." This patent mainly includes a washing tub body with four sets of electric lifting rods evenly distributed along the circumference of the side wall. The output end of each electric lifting rod has a cover plate, and a rotating shaft is rotatably connected to the cover plate. A rotating fixing mechanism is mounted on the rotating shaft and is plugged into the washing tub body. The rotating fixing mechanism has a clamping mechanism. An ultrasonic generator is located at the bottom of the washing tub body, and the ultrasonic generator has an ultrasonic transducer. The rotating fixing mechanism includes a fixing frame, a sliding groove, a telescopic frame, a return spring, and a connecting rod. The clamping mechanism includes a fixing plate, a pull rod, a clamping spring, and an anti-slip clamp. While this patent can fix circuit boards of different sizes and clamp both ends of the circuit boards, it does not provide a comprehensive solution.
