Fixtures and Test Equipment

Abstract

The invention provides a fixing device and test equipment. The fixing device comprises a workbench used for storing components to be fixed. The workbench at least comprises a first frame and a secondframe which are oppositely arranged. The side, far away from the second frame, of the first frame is provided with positioning components which are used for positioning the edges of the components tobe fixed. The first frame is connected with a movable structure. The movable structure can enable the first frame to move towards or away from the second frame so that the distance between the positioning components and the first frame can be changed. By means of the fixing device and the test equipment, the point teaching difficulty of the equipment can be lowered, the stability of taking the components to be fixed of a carrier clamp is improved, the situation that the carrier clamp and the frames of the workbench rub and interfere with the frames when the components to be fixed are taken andput is avoided, and the equipment downtime is reduced.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a fixing device and testing equipment. Background technique [0002] In the manufacturing process of the display screen, multiple inspection procedures are required to detect defects in the manufacturing process in time. For example, the boxed display screens need to undergo a lighting test (Cell Test), which simulates the lighting of the backlight module (Module), lights up the display screen for input signals, and conducts a visual test. [0003] When performing a lighting test, the display screen is placed on the worktable of the test equipment. The worktable includes a frame, which is generally placed vertically and surrounded by four frames: upper, lower, left, and right. A positioning component (Worktable Stopper) is provided outside the lower frame for supporting and positioning the edge of the display screen. During the test, the display screen is picked a...

Problems solved by technology

And the lower frame of the workbench must avoid entering the display area of ​​the display screen. Therefore, the distance from the lower frame to the positioning part cannot exceed the black matrix size (BM Size) on the display screen. Therefore, the height that the handling arm can grip Limited by the size of the black matrix of the display screen and the width of the lower frame of the workbench, the height S that the handling arm can grip: S=D1-D2, where D1 is the width of the black matrix at the edge of the display screen, and D2 is the width of the lower frame , when corresponding to the ultra-narrow frame (BM Size<3mm), the height S that can be picked up by the handling arm is only less than 1mm, which makes it more difficult to teach the equipment (Teaching) at the equipment point, and the stability of the clamping screen of the handling arm is reduced. Increased downtime
