Problems solved by technology

The traditional method is to place the circuit board on the table first, then move the suction nozzle on the vertical table downward so that the photoelectric conversion lens is placed between the circuit board and the optical fiber, and then judge the photoelectric conversion between the photoelectric conversion lens and the circuit board by intercepting the image. Whether the chip is aligned, but because the suction nozzle is located above the circuit board, it is easy to interfere with the image interception, which in turn brings inconvenience to the alignment of the photoelectric conversion lens and the photoelectric conversion chip on the circuit board

Abstract

A suction device, which is used to place a photoelectric conversion lens between a circuit board and an optical fiber, the suction device includes a base and a suction nozzle, the base includes an upper surface and a lower surface oppositely arranged, from the A receiving hole is opened from the upper surface to the lower surface, the central axis of the receiving hole is inclined relative to the upper surface, and the suction nozzle is telescopically accommodated in the receiving hole. In this way, the suction nozzle can be prevented from interfering with the image capture of the circuit board-side lens and the photoelectric conversion chip, which facilitates accurate alignment between the photoelectric conversion lens and the photoelectric conversion chip on the circuit board.

Description

technical field [0001] The invention relates to a suction device, in particular to a suction device for suctioning a photoelectric conversion lens. Background technique [0002] At present, the photoelectric conversion module has been widely used in the field of optical communication transmission. The photoelectric conversion module generally includes a laser diode, a circuit board, a photoelectric conversion lens, an optical fiber and a photodiode. After the laser diode emits an optical signal, the optical signal enters the photoelectric conversion lens for transmission, and finally enters the photodiode. The optical signal is converted into an electrical signal by the photodiode, thereby achieving the purpose of photoelectric conversion. [0003] The photoelectric conversion lens, as an important component in the photoelectric conversion module, generally needs to be tested for optical coupling power loss. During this process, it is necessary to align the photoelectric con...
