Abstract

The invention relates to an auxiliary detector for front and back sides of a display screen. The auxiliary detector comprises a first transmission mechanism installed on a workbench, a rotating motoris slidably connected with the first transmission mechanism through a first transmission seat and can moving linearly along the X-axis direction, and a first sucker part is connected to the rorating motor; a support is arranged over the workbench, a second transmission mechanism is installed on the support, a lifting arm is in sliding connection with a second conveying mechanism through a second conveying base and can move linearly along the Y-axis direction, the bottom of the lifting arm is connected with a second sucker part, the second sucker part is hung between the first conveying seat and the second conveying seat and is opposite to the first sucker part, and can be driven by the lifting arm to move up and down along the Z-axis direction, and the axes X, Y and Z are vertical to one another. The technical problems that time and labor are wasted and the liquid crystal screen is prone to damage when the front and back sides of the liquid crystal screen are changed at present are solved, stability and reliability are achieved, and work is efficient.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing. More specifically, the invention relates to an auxiliary detection device for the front and back of a display screen. Background technique [0002] The liquid crystal screen is a display screen with higher definition. It is generally assembled by a liquid crystal substrate and a printed circuit board (ie, a PCB board). The liquid crystal substrate is filled with liquid crystal materials. The printed circuit board can change the liquid crystal in the liquid crystal substrate through voltage The arrangement of molecules inside the material is used to achieve the purpose of shading and light transmission to display images of different shades and patches. [0003] At present, in the field of LCD screen production, assembly line production is more and more widely used. The LCD substrates and printed circuit boards assembled on the assembly line need to be inspected on the front and b...
