Embodiment 1

[0027] like figure 1 , 2 As shown, an automatic alignment mechanism for liquid crystal panel detection, the alignment mechanism includes a module pallet 1 and a test head device; the module pallet 1 is provided with a cavity 11 for placing a liquid crystal panel 100 to be tested , and a first socket 111 that matches the position of the cavity 11;

[0028] The detection head device includes a first connecting plate 2, a second connecting plate 3, a probe mounting block 4 and a guide shaft 5 arranged in sequence from top to bottom; The panel 100 is in contact with the probes 9 , and the probe mounting block 4 is also provided with a probe protection plate 42 for protecting the needles of the probes 9 . One end 51 of the guide shaft 5 is fixedly connected to the probe mounting block 4 , and the other end 52 is used to be inserted into the first insertion hole 111 .

[0029] A joint bearing 6 is arranged between the first connecting plate 2 and the second connecting plate 3 , a...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that: the upper end 72 of the angle limiting shaft 7 is fixed on the first connecting plate 2, and the lower end 71 of the angle limiting shaft 7 is inserted in the second In the third socket corresponding to the lower end of the angle limiting shaft 7 provided on the connecting plate 3, and between the outer wall of the lower end 71 of the angle limiting shaft 7 and the hole wall of the third socket Leave gaps.

Abstract

The invention discloses an automatic aligning mechanism for detecting a liquid crystal display panel. The automatic aligning mechanism comprises a module carrying plate and a detecting head device. The detecting head device comprises a first connecting plate, a second connecting plate and a probe installation block which are sequentially arranged from top to bottom. A joint bearing is arranged between the first connecting plate and the second connecting plate. An angle limiting shaft is arranged between the first connecting plate and the second connecting plate. The second connecting plate is connected with the probe installation block through height-equal screws. A probe making contact with the to-be-detected liquid crystal display panel is arranged on the probe installation block. By means of the arrangement, when the detecting head device is pressed down, automatic alignment can be achieved, then a guide shaft is smoothly inserted in a lining, and the probe can more conveniently, rapidly and precisely make contact with detecting points on the to-be-detected liquid crystal display panel.

Description

technical field [0001] The invention relates to a detection mechanism, in particular to a liquid crystal panel detection automatic alignment mechanism. Background technique [0002] In the liquid crystal panel detection process, it is necessary to apply a voltage to the liquid crystal, and generally there are test points on the TFT layer of the liquid crystal panel for voltage application. There will be a test head on the liquid crystal panel inspection equipment, and some conductive parts (such as FPC, POGO PIN, etc.) on the test head will be connected to the test points one by one to realize power-on. [0003] As mentioned above, the test head and the panel need precise alignment on the mechanism. In the prior art, if a test head corresponds to a panel, most of them use high-precision processing and assembly to achieve the alignment accuracy; but in the automatic assembly line , It often happens that one test head corresponds to multiple modules. In this case, most of the...
