[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle of optical fiber is "total reflection of light". Currently, the application of optical fiber has moved towards integration. Fiber optic arrays, as one of the forms, are often used for precise and reliable coupling with semiconductor lasers or other optical array structures on integrated circuit chips. When using optical fiber, the length of the optical fiber is often insufficient, and the optical fiber head needs to be docked and connected to other devices.

[0003] To this end, the China Patent Network has disclosed an optical fiber array positioning device with application number 201921647722.0. By bringing the optical fiber array close to the suction device, the two surfaces of the optical fiber array are respectively close to the first plane and the second plane. When the suction device completely adsorbs the optical fiber array, the clamping device presses the optical fiber array, and the positioning is reliable. When disassembling or replacing the other side for testing, it is only necessary to reset the clamping device and remove the optical fiber array from the suction device. It is simple to use, and the operator can complete the fixation of the optical fiber array with one hand and one action, thereby improving work efficiency.

[0004] Although the above application has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: since the suction device uses gas to position the two sides of the optical fiber array when positioning the optical fiber array, when the two side surfaces of the optical fiber array are not completely flat, air leakage is likely to occur, affecting the positioning effect of the optical fiber array. Based on this, the utility model designs a optical fiber array positioning device to solve the above problems. Utility Model Content
