[0002] LCM module refers to liquid crystal display module, which is an integrated circuit board, mainly composed of LCD screen, control board, PCB board, backlight, etc. IR hole refers to infrared receiving hole, which is usually used to receive infrared signals to realize remote control function.

[0031] Specifically, a driving knob 222 is rotatably connected to the top of the positioning frame 221, and the driving knob 222 passes through the shielding frame 211. A driving belt 223 is surrounded by the bottom of the driving knob 222, and a transmission roller 229 is surrounded by the end of the driving belt 223 away from the driving knob 222. Both ends of the driving belt 223 are provided with a linkage belt 224, and both ends of the inner side of the linkage belt 224 are surrounded by the transmission roller 229. The inner side of the positioning frame 221 is slidably connected with a horizontal supporting plate 1 225 and a horizontal supporting plate 2 226. The transmission roller 229 is rotatably connected to the inside of the positioning frame 221, and the driving belt 223 and the linkage belt 224 are both movably connected to the inside of the positioning frame 221.

[0032] In this embodiment, there are transmission rollers 229 at the bottom of the driving knob 222, on one side of the linkage belt 224, and at the intersection of the linkage belt 224 and the driving belt 2 223. The transmission roller 229 is also composed of a shaft and a gear fixedly connected, wherein the gear is in contact with the inner side of the driving belt 223 and the linkage belt 224; the horizontal supporting plate 1 225 and the horizontal supporting plate 2 226 are both made of transparent materials and have the same function as the vertical supporting plate 1 215 and the vertical supporting plate 2 216.

[0033] Specifically, both ends of the transverse supporting plate 1 225 and the transverse supporting plate 2 226 are inserted with fixing pins 228, and the side opposite to the transverse supporting plate 1 225 and the transverse supporting plate 2 226 is fixedly connected with a shielding plate 227, and both ends of the transverse supporting plate 1 225 are fixedly connected to one side of the linkage belt 2 224 through the fixing pins 228, and the transverse supporting plate 2 226 is fixedly connected to the side of the linkage belt 2 224 away from the transverse supporting plate 1 225 through the fixing pins 228.

[0034] In this embodiment, the shielding plate 227 is consistent with the shielding plate 217, and the two ends of the shielding plate 227 are fixedly connected to the grooves on one side of the horizontal supporting plate 1 225 and the horizontal supporting plate 226 for storing and unfolding the length of the shielding plate 227. At the same time, the width of the shielding plate 227 is shorter than the length of the horizontal supporting plate 1 225 and the horizontal supporting plate 226, so that it can cooperate with the shielding plate 217 above to shield the light-emitting area of ​​the LCM module and leak out the area bonded with the shading glue; similarly, the horizontal supporting plate 1 225 and the horizontal supporting plate 2 The connection between 226 and the linkage belt 224 through the fixing pin 228 is on the different side of the linkage belt 224, which is consistent with the above-mentioned linkage belt 1 214. Therefore, when the linkage belt 224 rotates, the two horizontal supporting plates 1 225 and the horizontal supporting plates 2 226 will move closer to or away from each other, and the shielding plate 227 will be unfolded when they move away, and the shielding plate 227 will be retracted when they move closer. The horizontal supporting plates 1 225 and the horizontal supporting plates 2 226 are both made of transparent materials and are consistent with the vertical supporting plates 1 215 and the vertical supporting plates 2 216 above.

[0035] Specifically, a sliding groove is provided on the inner side of the shielding frame 211 for sliding of the longitudinal supporting plate 1 215 and the longitudinal supporting plate 216 , and a sliding groove is also provided on the inner side of the positioning frame 221 for sliding of the transverse supporting plate 1 225 and the transverse supporting plate 2 26 .

[0036] In this embodiment, the sliding groove directions of the shielding frame 211 and the positioning frame 221 are inconsistent. The sliding groove of the shielding frame 211 is used for the horizontal sliding of the longitudinal supporting plate 1 215 and the longitudinal supporting plate 216, while the sliding groove of the positioning frame 221 is used for the longitudinal sliding of the transverse supporting plate 1 225 and the transverse supporting plate 2 26.

[0037] Specifically, a spring 33 surrounds the periphery of the limiting column 32 , and the spring 33 is located above the receiving block 34 . Two linkage blocks 35 are fixedly connected to one side of the positioning frame 221 , and the linkage blocks 35 are used for the staff to lift the shielding mechanism 2 .

[0038] In this embodiment, the inspection table 1 is a common inspection table with a connector on the top for connecting the LCM module and making it light up through a switch; after lifting the shielding mechanism 2, the spring 33 will shrink. At this time, after placing the LCM module, loosening the linkage block 35 will allow the spring 33 to rebound and then position the LCM module located above the placement table 31 and below the shielding mechanism 2, without the need for a positioning mold.

[0039] The working principle and use process of this utility model:

[0040] When the light leakage detection of the LCM module is required, the staff member needs to lift the shielding mechanism 2 through the linkage block 35 with his fingers, which will cause the spring 33 above the receiving block 34 to contract. At this time, the LCM module is placed between the placement table 31 and the shielding mechanism 2 and the connecting end of the LCM module is connected to the detection table 1, so that the LCM module lights up for detection. Therefore, different models of LCM modules can be positioned;

[0041] After positioning the LCM module, the staff can rotate the adjustment knob 212 to adjust the distance between the longitudinal receiving plate 1 215 and the longitudinal receiving plate 216 to allow the shielding plate 217 to unfold and shield the horizontal light-emitting area of ​​the LCM module, and rotate the driving knob 222 to adjust the distance between the transverse receiving plate 1 225 and the transverse receiving plate 226 to allow the shielding plate 227 to unfold and shield the longitudinal light-emitting area of ​​the LCM module, thereby facilitating the staff to observe whether the area with the shading glue is leaking through the transparent longitudinal receiving plate 1 215, the longitudinal receiving plate 216, the transverse receiving plate 1 225, and the transverse receiving plate 226;

[0042] When the adjusting knob 212 is rotated, the connecting roller 219 fixedly connected to the bottom of the adjusting knob 212 will make the driving belt 1 213 rotate clockwise, and then the linkage belts 1 214 at both ends of the driving belt 1 213 will rotate clockwise. Since the two ends of the longitudinal receiving plate 1 215 are fixedly connected to one side of the linkage belt 1 214 through the positioning pins 218, and the two ends of the longitudinal receiving plate 216 are fixedly connected to the side of the linkage belt 1 214 away from the longitudinal receiving plate 1 215 through the positioning pins 218, the longitudinal receiving plate 1 215 and the longitudinal receiving plate 216 will move away from each other, so that the shielding plate 217 between the longitudinal receiving plate 1 215 and the longitudinal receiving plate 216 is unfolded.

[0043] When the driving knob 222 is rotated, it will make the driving belt 223 rotate clockwise through the transmission roller 229 fixedly connected to the bottom of the driving knob 222, and then make the linkage belt 224 at both ends of the driving belt 223 rotate clockwise. Since the two ends of the transverse supporting plate 1 225 are fixedly connected to one side of the linkage belt 224 by the fixing pin 228, and the two ends of the transverse supporting plate 226 are fixedly connected to the side of the linkage belt 224 away from the transverse supporting plate 1 225 by the fixing pin 228, the transverse supporting plate 1 225 and the transverse supporting plate 226 will move away from each other, so that the shielding plate 227 between the transverse supporting plate 1 225 and the transverse supporting plate 226 will unfold.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
