The invention relates to a gauge for measuring the bounce flexibility. The gauge is simple in structure, high in measurement accuracy, convenient to measure, suitable for multiple size specifications and low in cost. The gauge comprises a base, a connecting rod arranged on the base in a rotatable mode, a panel arranged at the upper end of the connecting rod and used for locating a measured part, a measurement support arranged on the connecting rod and a plurality of measurement indication meters arranged on the measurement support, two sliding grooves are formed in the panel in the radial direction, sliding blocks are arranged in the two sliding grooves respectively in the mode of being capable of sliding along the sliding grooves, spindles are arranged on the two sliding blocks respectively, bearings are arranged on the two spindles respectively in a rotatable mode, the two bearings respectively protrude out of the surface of the panel, and the two spindles are locked on the panel through fastening screws.

The invention relates to a method for locating an electric object stage. The method mainly solves the problem in the prior art that an object stage can not locate an object precisely. The method includes the following steps: (a) matching threaded structures of supporting columns on a supporting frame of the object stage with screw holes of a base table, fixing the supporting columns on the base table, and then fixing plungers on the base table; (b) fixing eccentric pins on the base table and connecting the lower ends of the eccentric pins with rotating mechanisms of motors; (c) by adjusting the threaded structures of the supporting columns of the supporting frame, adjusting the supporting columns vertically to enable upper end points to be in a horizontal plane, placing a object to be carried on the supporting frame, and clamping the object to be carried between the plungers and the eccentric pins; (d) controlling a motor on one side of the object to be carried to rotate to enable the eccentric pin axes to be close to or away from the object to be carried, simultaneously adjusting a motor on the opposite side of the object to be carried to rotate to enable the eccentric pin axes to be away from or close to the object to be carried; and (e) adjusting motors at other positions to enable the object to be carried to be fixed. By means of the technical scheme, the problem is well solved, and the method can be used in locating operation of the object stage of precise operation.

The invention relates to a position electrically controllable object stage which mainly solves the problem that an object stage in the prior art cannot position an object accurately. The position electrically controllable object stage comprises a base station, supporting columns, plungers, eccentric pins and motors, wherein the supporting columns, the plungers and the eccentric pins are fixed on the base station, the heights of the eccentric pins and the plungers are higher than those of the supporting columns in the direction perpendicular to the base station, and a plane is formed by peaks of supporting positions of the supporting columns. An object to be carried is placed at the supporting positions of the supporting columns, the edge of the object to be carried is contacted with the eccentric pins and the plungers, at least one plunger is located at the position opposite to the eccentric pins, the lower ends of the eccentric pins are provided with rotating mechanisms matched with the motors, and the motors are fixed below the eccentric pins. The position electrically controllable object stage solves the problem of inaccuracy well and can be applied to industrial production of object stages for accurate operation.

The invention discloses an automatic loading and unloading system suitable for functional testing equipment, comprising: a first conveying mechanism group, a second conveying mechanism group and a third conveying mechanism group; the first conveying mechanism group moves along the first direction; the second conveying mechanism group The mechanism group moves along the first direction; the first conveying mechanism group and the second conveying mechanism are arranged in sequence along the second direction; the third conveying mechanism group moves along the second direction, when the third conveying mechanism group moves to the first position, The third conveying mechanism group docks with the first docking end; when the third conveying mechanism group moves to the second position, the third conveying mechanism group docks with the second docking end. The invention occupies a small area and has a high space utilization rate; it does not need to stop loading and unloading, and can realize a 24-hour uninterrupted working mode; it does not interfere with the mechanical arm, and optimizes the walking path of the mechanical arm; it greatly improves the productivity and performance of the functional testing equipment. output.

The invention discloses a power meter detection method which integrates the positioning information of a patrol inspection robot. The present invention is mainly divided into four steps: (1) the inspection robot arrives at the designated position to obtain pictures; (2) combines the positioning information of the inspection robot, and uses Fourier and phase correlation technology to roughly locate the target instrument area; (3) Using machine learning to accurately locate the target instrument area, multiple target candidate areas are obtained; (4) Fuse the positioning information of the inspection robot to calculate the characteristic parameters of multi-feature fusion such as IoU, mutual information, visual hash, etc., and use these parameters to screen candidate areas. Candidate area to get the final target. The invention utilizes machine learning to detect instruments under various illumination and posture changes.
