A network inspection machine with the functions of shading and amplitude modulation, deviation correction and anti-swing, and its use method

Abstract

The invention discloses a net inspection machine with the functions of shading and amplitude modulation, deviation correction and anti-swing, which comprises a frame and a net inspection workbench installed on the frame, a screen is installed on the net inspection workbench, and the screen A light box is installed on the back of the light box. One side of the light box is a glass transparent box. A telescopic shading cloth box is installed on both sides of the light box. A telescopic shading cloth is installed in the telescopic shading cloth box. The top of the telescopic shading cloth is movably connected to the two sides of the screen. Two U-shaped structure baffles are installed on the screen inspecting machine, on the unfolding of the screen and on the winding and bundling path. The invention reduces the interference source of the net inspection, and solves the problem that the light stimulates the vision when the screen is inspected on the net inspection machine. The screen inspection machine does not stop any operation, and does not need to add any operation, it can automatically realize the neat and beautiful screen roll bundle. The invention has the advantages of simple structure, simple operation, no hand injury, and the network inspection efficiency can be increased by more than 4 times.

Description

technical field [0001] The invention relates to a network inspection machine with the functions of shading and amplitude modulation, deviation correction and swing prevention. Background technique [0002] The screen inspection machine is a special machine for inspecting whether there are defects such as broken wires in the screen. [0003] Existing screen inspection machines have changed from external lighting to internal lighting, but the radiant light from the internal lighting is likely to stimulate the vision of the machine operator and interfere with the observation and inspection of the screen. However, because the screens have different widths and lengths, no method of blocking light to stimulate vision has been taken. [0004] Moreover, the existing screen inspection machine adopts a disc that rotates synchronously with the shaft to correct the deviation and prevent swinging, which cannot make the screen rolls neatly bundled. Therefore, in the process of operation...
