    • A fixed-focus lens module includes an outer lens barrel, an inner lens, a first lens, and a second lens group. The outer lens barrel includes a first open end, a first cavity, and a second open end arranged in the order from the object side to the image side of the outer lens barrel. The inner lens barrel is received in the outer lens barrel adjacent to the first open end. The first lens is received in the inner lens barrel. The second lens group is received in the outer lens barrel adjacent to the second open end. An gap is defined between an outer wall of the inner lens barrel and an inner wall of the outer lens barrel at the first open end, and the center axis of the inner lens barrel is adjustable relative to the outer lens barrel for adjusting the alignment between the first lens and the second lens group.

    • An injection mold for molding a lens barrel is disclosed. The injection mold includes a female die, a male die and a screw die. The female die and the male die are correspondingly connected to two ends of the screw die. The female die, the male die and the screw die cooperatively define a mold cavity. The female die includes a female die plate and a female die core protruding from the female die plate. The male die includes a male die plate and a male die core protruding from the male die plate. The male die defines a through hole passing through the male die plate and the male die core. An air gap is formed between the distal ends of female die core and the male die core, the air gap is communicated with the mold cavity and the through hole.

    • An apparatus for grinding a threaded portion of a workpiece, is provided. The threaded portion has a spiral groove formed therein. The apparatus includes a motor, a grinding cord, a detector and a controller. The motor has a rotary portion for rotating the threaded portion of the workpiece about an axis. The grinding cord is configured for being looped around the threaded portion of the workpiece with a middle part thereof engagingly received in a given portion of turns of the spiral groove for grinding the thread portion of the workpiece. The detector is for detecting a rotating cycle of the rotary portion. The controller is communicatively coupled to the detector for controlling the rotary portion to selectively rotate in a first rotating direction or in a reverse second rotating direction based on the received signal from the detector.
    • 提供了一种用于研磨工件的螺纹部分的装置。 螺纹部分形成有螺旋槽。 该装置包括马达,研磨绳,检测器和控制器。 马达具有用于使工件的螺纹部分围绕轴线旋转的旋转部分。 研磨线被构造成围绕工件的螺纹部分环绕,其中间部分接合地容纳在螺旋槽的给定弯道部分中,用于研磨工件的螺纹部分。 检测器用于检测旋转部分的旋转周期。 控制器通信地耦合到检测器,用于基于来自检测器的接收信号,控制旋转部分沿第一旋转方向或反向第二旋转方向选择性地旋转。
