The device disclosed by this utility model comprises a working platform, a vertical column and a testing platform, wherein a tester capable of longitudinally sliding is arranged on the vertical column; the vertical column is fixed on the working platform through a vertical rotating mechanism; the vertical rotating mechanism comprises a vertical board and a rotary locating component rotationally connected to one side of the vertical board through a decelerating motor; the bottom end of the vertical board is fixed on the working platform; the rotary locating component is clamped on the lower end part of the vertical column; the testing platform is fixed on a sliding block through a horizontal rotating and lifting mechanism; and the sliding block is connected to the working platform in a sliding manner through a transverse sliding rail and a longitudinal sliding rail.
Description
Technical field
The utility model relates to a kind of measurement mechanism of liquid crystal panel, and relating in particular to a kind of tester can left and right swing in same perpendicular, simultaneously the automatic detection platform of photoelectric properties of the test platform liquid crystal panel that can rotate automatically or go up and down again.
Background technology
Liquid crystal panel is widely used in televisor, desktop computer and notebook computer etc. as display; And photoelectric properties are key technical index of decision liquid crystal panel quality; Conventional detection generally is that through can liquid crystal panel being detected along the tester that X axle, Y axle and three directions of Z axle move, wherein the measuring head of tester all the time vertically downward again with being placed on the measuring table of liquid crystal panel level; When thus the liquid crystal panel of special shape being detected; When the converted measurement face, often need liquid crystal panel be removed the back second positioning, the measurement that makes the conversion liquid crystal panel is not only wasted time and energy towards last; Inefficiency, and second positioning directly causes measuring accuracy to reduce.
Chinese patent discloses a kind of liquid crystal panel detection device and liquid crystal panel detecting method (CN101813835A), and this device comprises signal input module, is used to liquid crystal panel to be detected shows signal and variable public electrode voltages signal are provided; Detection module is used for when said signal input module is imported different public electrode voltages signals, the zone to be detected of said liquid crystal panel to be detected being detected, and obtains the brightness of said zone to be checked under different public electrode voltages signals and detects data; Detection platform; Be used to carry said liquid crystal panel to be detected; And the said detection module of control can move on the detection platform to reach the brightness situation that detects arbitrary region liquid crystal panel on the surface level; And the public electrode voltages acquisition brightness flicker of passing through the adjustment liquid crystal panel shows that for differentiating electricity inequality and non-electricity show that inequality provides basis for estimation with the public electrode voltages situation of change.Measuring head in this device equally all the time vertically downward; Therefore same when existing liquid crystal panel to special shape to detect, when the converted measurement face, need liquid crystal panel be removed the back second positioning, not only waste time and energy; Inefficiency, and directly cause problems such as measuring accuracy reduction.
Summary of the invention
The utility model has mainly provided a kind of tester can left and right swing in same perpendicular; Test platform can rotate or go up and down again automatically simultaneously; Thereby need not second positioning and get final product the omnibearing automatic detection platform of photoelectric properties that liquid crystal panel is detected; When having solved the liquid crystal panel that exists in the prior art and detecting, need the liquid crystal panel second positioning be come the converted measurement face, not only waste time and energy special shape; Inefficiency, and directly cause technical matterss such as measuring accuracy reduction.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: the automatic detection platform of a kind of photoelectric properties of liquid crystal panel; Comprise workbench and be located at column and the test platform on the workbench; But on said column, be provided with the tester of straight skidding; Said column is fixed on the workbench through vertical rotating mechanism; Said vertical rotating mechanism comprises riser and is rotatably connected at the positioning of rotating member of riser one side through reducing motor that the bottom of said riser is fixed on the workbench, and said positioning of rotating member is clamped in the bottom of column; Said test platform is fixed on the slide block through horizontally rotating elevating mechanism, and said slide block is slidingly connected on the table top of workbench through horizontal slide rail and vertical slide rail.Tester is contained on the column; Column is fixed on the workbench through vertical rotating mechanism again, can rotate through the reducing motor driven rotary align member in the vertical rotating mechanism during use, and the column that the positioning of rotating member drives clamping again rotates; Make the tester left and right swing in perpendicular on the column; When measuring the liquid crystal panel of special shape, promptly drive the two sides that tester points to liquid crystal panel at forward or retrograde rotation thus, carry over the distance that tester is regulated in the upper and lower slippage of column through tester again through reducing motor; Simultaneously because test platform is used for bearing liquid crystal display panel; Can be further the position that liquid crystal panel is adjusted in elevating mechanism and horizontal and vertical slippage that horizontally rotates through test platform, need not the liquid crystal panel second positioning is come the converted measurement face, measuring accuracy is high; It is time saving and energy saving to operate, and increases work efficiency.
As preferably; Said positioning of rotating member comprises and coaxially is fixed on the rotation basal disc on the reducing motor output shaft and is symmetrically set in two clamps on the rotation basal disc outer face; On said clamp, be provided with several axial location holes and radial location hole; Said clamp is fixed on the rotation basal disc through the axial location hole, and said clamp grips column through the radial location hole.Through on the outer face of rotation basal disc, two clamps being set; And on the axial vane surface of clamp and sagittal plane, several pilot holes are set respectively; Passing the axial location hole with bolt is fixed on clamp on the rotation basal disc; The radial location hole of passing and arranged on left and right sides with bolt is fixedly clamped column between two clamps, and is simple in structure, easy accessibility.
As more preferably, be provided with balancing weight in the bottom of said column, said balancing weight is through being bolted on the column.Lower end through at column is provided with balancing weight, makes the two ends holding torque balance of column, improves the stability in use of device.
As preferably; The outside corresponding to the positioning of rotating member on said riser is provided with sensor; On said positioning of rotating member, be provided with three sensing chips corresponding at least with sensor; Wherein have two sensing chips respectively level be located at the both sides of column, one of them sensing chip and tester homonymy be positioned at the positioning of rotating member directly over.Through be provided with on the riser one with the positioning of rotating member on the sensing chip corresponding sensor, when the positioning of rotating member drove the column rotation, sensor can come the rotation of control positioning of rotating member automatically through the signal that receives on the sensing chip; The rotation of column just; Through on the corresponding positioning of rotating member in column both sides, a sensing chip being set respectively, make when column is left and right to be rocked to level to stop automatically, to avoid tester and liquid crystal panel interference and collision; Through with the positioning of rotating member of tester homonymy directly over a sensing chip is set; Can make tester revolve playback on automatically where necessary, easy to use, automaticity is high.
