Description
Technical Field
The utility model relates to a TFT module field especially relates to a general logical no-go gage tool of TFT.
Background
In the measuring tool for detecting the size of the TFT, since the product is qualified within the measurement range, the detection is usually performed by using a go-no-go gauge; when the existing go-no go gauge is used for detecting a TFT module, the thickness of different positions needs to be detected, so that the go-no go gauge needs to be replaced for detection, and the go-no go gauge needs to be replaced again according to the difference of drawing tolerance, so that the management and manufacturing cost of multiple go-no go gauges is increased; therefore the utility model provides a general logical no-go gage tool of TFT, it detects the TFT module, need not to change logical no-go gage, has reduced because need make the cost-push that many money leads to the no-go gage and bring.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical scheme who uses does: the utility model provides a general no-go gage tool of TFT which characterized in that includes: a handheld frame and a variable sheet; two ends of the handheld frame are respectively and fixedly provided with a screw rod, each screw rod is provided with a moving block in a sliding mode, and a nut is installed on each screw rod in a meshed mode; the variable sheets are provided with a plurality of variable sheets, the variable sheets have various thicknesses, and at least two variable sheets with the same size and thickness are provided; the variable piece is used for limiting the distance between each moving block and the handheld frame; the nut is used for fixing the moving block and the variable quantity piece on the handheld frame so that the moving block and the variable quantity piece cannot move.
Further, the variable sheets of different thicknesses are different in color.
Further, each variable sheet is marked with a thickness value.
Further, the color of each moving block is different.
Furthermore, each moving block is marked with a fool-proof mark, and the fool-proof marks marked on each moving block are different.
Further, the nut is a butterfly nut.
Because the utility model adopts the above technical scheme, the utility model discloses the beneficial effect who has as follows:
one, the utility model discloses a variable piece can be measured the TFT module of difference, need not to change logical no-go gage, change, add or reduce the variable piece can, reduced the cost of management and the many money logical no-go gage of manufacturing.
Two, because the utility model discloses the handheld frame both ends all can be measured, consequently when measuring the soldering tin thickness in a poor light of TFT module and TFT thickness, need not to change the variable piece.

Detailed Description
In one embodiment, as shown in fig. 1 to 3, a TFT universal no-go gauge includes: a handheld frame 1 and a variable sheet 5; two ends of the handheld frame 1 are respectively and fixedly provided with a screw rod 3, each screw rod 3 is provided with a moving block 2 in a sliding way, and a nut 4 is arranged in a meshing way; the variable sheets 5 are provided in plurality, the variable sheets 5 have various thicknesses, and the variable sheets 5 with the same size and thickness are provided in plurality; the variable piece 5 is used for limiting the distance between each moving block 2 and the handheld frame 1; the nut 4 is used for fixing the moving block 2 and the variable displacement piece 5 on the handheld frame 1 so as to prevent the moving block and the variable displacement piece from moving; the variable sheets 5 with different thicknesses have different colors, and each variable sheet 5 is marked with a thickness value; the color of each moving block 2 is different, one moving block is yellow, the other moving block is brown, foolproof marks are engraved on each moving block 2, and bold big characters T are engraved on the yellow moving blocks 2 to represent that the moving blocks are used for measuring the thickness of the TFT; a bold big character B is marked on the brown moving block 2 and represents that the bold big character B is used for measuring the thickness of the backlight soldering tin; the nut 4 is a butterfly nut and is convenient to rotate;
manufacturing a variable sheet 5 according to the lower limit of the thickness of a TFT module in the prior industry, namely 1.97mm, and the lower limit of backlight soldering tin, namely 0.45mm, manufacturing a plurality of variable sheets 5 according to 0.02 mm and 0.1mm, and placing the variable sheet 1.97mm between a yellow moving block 2 and a handheld frame 1 before measurement; placing a variable piece of 0.45mm between a brown moving block 2 and a handheld frame 1, padding other variable pieces 5 at each end according to the actual tolerance thickness of a drawing, and then screwing two nuts 4 by hands to fix the variable pieces 5 between the moving block 2 and the handheld frame 1 and enable a gap with the sum of the thicknesses of the variable pieces 5 to exist between the handheld frame 1 and the moving block 2 at each end; and then, the handheld frame 1 can be held to measure the thickness of the TFT module and the upper limit of the thickness of the backlight soldering tin, qualified products can enter a gap between the movable block 2 and the handheld frame 1, and unqualified products cannot enter the gap (note that the lower limit of the TFT module does not need to be measured).
