The invention provides an optical fiber array, a preparation method of the optical fiber array and an optical device. The optical fiber array comprises optical fibers and a substrate; the optical fiber is used for emitting light beams; the substrate is provided with an accommodating groove, a reflecting surface and a light emitting surface, the accommodating groove and the reflecting surface are arranged at intervals along the length direction of the substrate, the reflecting surface is positioned on one side of the end part of the accommodating groove, the reflecting surface and the light emitting surface are arranged at intervals along the height direction of the substrate, and at least part of the optical fiber is arranged in the accommodating groove; a light beam emitted from the optical fiber is emitted to the reflecting surface, is reflected to the light-emitting surface through the reflecting surface, and is emitted out of the substrate through the light-emitting surface. The accommodating groove, the reflecting surface and the light emitting surface are formed on the substrate by utilizing a photoetching process, so that the process of mutually assembling a lens and the substrate in the related technology is omitted, the use quantity of a lens material is reduced, and the assembly cost, the material cost and the production cost are reduced. Moreover, the subsequent packaging process is simplified, the spacing tolerance between the accommodating grooves is reduced, and the miniaturization of the optical device is realized.

This utility model discloses a proportional electromagnet with preload adjustment function, belonging to the field of hydraulic technology. The proportional electromagnet includes a shell, a coil assembly, a tail yoke, an armature assembly, and an adjustment assembly. The shell includes an integrally formed shell body and a front yoke, with an opening at the end of the shell body opposite to the front yoke. The tail yoke is disposed within the shell body and is positioned opposite the front yoke. The coil assembly is disposed within the shell body and surrounds the front yoke and tail yoke. The armature assembly includes an armature and a push rod connected to the armature. The armature can move relative to the tail yoke when the coil assembly is energized, simultaneously driving the push rod to move relative to the front yoke. The adjustment assembly includes an adjustment seat, an adjustment rod, and an adjustment spring. The adjustment seat is installed at the opening of the shell body, and the adjustment rod is axially adjustable on the adjustment seat. The two ends of the adjustment spring respectively abut against one end of the adjustment rod and the armature. The proportional electromagnet can meet the needs of various working conditions, has strong versatility, is easy to process, and has high assembly efficiency.

The utility model relates to a kind of diamond trimmer, include: substrate;At least one first abrasive island, form in the one side of the substrate;And at least one protruding part, form in the one side of at least one first abrasive island relative to the substrate, wherein: the substrate, the at least one first abrasive island and the at least one protruding part are integrally formed, since omitting assembly process in forming process, and avoid using composite material or metal material, thus can greatly improve manufacturing precision and prevent pollution;In addition, the arrangement form of first abrasive island is various, after combining the protruding part of multiple shapes, can be adapted to the demand and use scene of various grinding, and can ensure that grinding fluid and grinding debris can flow smoothly and discharge in the process of diamond trimmer rotation and sweeping.
