[0026] like Figure 1-6As shown, a quality inspection device for LCD liquid crystal display panels comprises an inspection box 1, the upper end surface of the inspection box 1 is penetrated with a feed port, and a flip cover 2 is rotatably installed at a position corresponding to the feed port on the upper surface of the inspection box 1, an observation platform 3 is fixedly installed on the outer wall of one end of the inspection box 1, a support frame 4 is fixedly installed inside the inspection box 1, two groups of sliding frames 5 distributed up and down are fixedly installed on the support frame 4, two groups of mobile frames 6 are slidably installed on the two groups of sliding frames 5, and transfer platforms 16 are slidably installed at both ends of the two groups of mobile frames 6, a fixed box 7 is fixedly installed on the outer wall of the transfer platform 16, and telescopic clamping rods 8 are movably connected at both ends of the fixed box 7, and docking rails 15 are fixedly installed on the outer walls of the lower ends of the two groups of support frames 4, and the upper end surface of the docking rail 15 is flush with the bottom surface of the mobile frame 6 and the cross section of the docking rail 15 is the same as the cross section of the mobile frame 6;

[0027] When in use, the transfer platform 16 can slide on the mobile frame 6, the mobile frame 6 can slide on the sliding frame 5, the sliding frame 5 can pass through each assembly and detection station of the liquid crystal display panel, the cross section of the mobile frame 6 is the same as the cross section of the docking rail 15, and the transfer platform 16 can drive the fixed box 7 equipped with the telescopic clamping rod 8 to slide on the docking rail 15. When the liquid crystal display panel to be tested is clamped by the two sets of telescopic clamping rods 8 and moves with the mobile frame 6, the mobile frame 6 slides on the sliding frame 5 to the top of the detection box 1. When the mobile frame 6 When the bottom surface coincides with the upper end surface of the docking rail 15, the transfer platform 16 slides downward on the mobile frame 6. When the transfer platform 16 slides along the mobile frame 6 and the docking rail 15 to the inside of the detection box 1, the user can close the flip cover 2 so that the LCD display panel to be detected is in the dark environment inside the detection box 1. Then the user detects the LCD display panel. After the detection is completed, the transfer platform 16 slides upward to the mobile frame 6. The LCD display panel can be brought to the next assembly or detection step by sliding the mobile frame 6 on the sliding frame 5.

[0028] like Figure 4 and Figure 5 As shown, connecting rods 9 are provided between the two groups of telescopic clamping rods 8 arranged at both ends of the fixed box 7, and the two ends of the connecting rods 9 are respectively fixedly connected to the two groups of telescopic clamping rods 8. The connecting rods 9 are arranged between the two groups of connecting rods 9. When facing some LCD display panels with smaller width or vertical screens, the length of the two groups of telescopic clamping rods 8 can be adjusted to clamp and fix this type of LCD display panel through the connecting rods 9.

[0029] like Figure 4As shown, a through slot is provided through the outer wall of the detection box 1 on one side away from the observation platform 3, and slide rails 13 are fixedly installed on the outer wall of the detection box 1 on both sides of the through slot, and folding curtains 14 are provided between the upper and lower ends of the two sets of slide rails 13. The lengths of the two sets of folding curtains 14 can be adjusted. By adjusting the two sets of folding curtains 14, the end of the transmission line connected to the back of the liquid crystal display panel to be detected in the detection box 1 can be extended to the outside of the detection box 1. At the same time, the cooperation of the two sets of folding curtains 14 can be used to shield the through slot provided on the detection box 1.

[0030] like Figure 4 As shown, an adjustment frame 11 is fixedly installed on the outer wall corresponding to the detection box 1 and the slide rail 13, and a mobile socket 12 is slidably installed on the adjustment frame 11. The mobile socket 12 can slide on the adjustment frame 11 and can be used to adjust the position of the mobile socket 12, thereby facilitating the user to plug the transmission line on the back of the liquid crystal display panel to be detected into the mobile socket 12.

[0031] like Figure 4 As shown, the ends of the two groups of folding curtains 14 are fixedly connected to the upper and lower ends of the two groups of slide rails 13 respectively, and the other ends are slidably connected to the two groups of slide rails 13 respectively. One end of the two groups of folding curtains 14 is fixed, and the other end is slidably connected to the two groups of slide rails 13. The movable ends of the two groups of folding curtains 14 can be pulled by the user to stay at any position on the slide rail 13.

[0032] like Figure 4 As shown, the cross-section of the adjustment frame 11 is C-shaped, and the two ends of the adjustment frame 11 are fixedly connected to the outer walls of the detection box 1 located on both sides of the slide rail 13. The special shape of the adjustment frame 11 allows the adjustment frame 11 to be installed in the middle of the two sets of slide rails 13 without affecting the normal use of the folding curtain 14 in the slide rail 13, thereby facilitating the transmission line on the back of the liquid crystal display panel to be detected in the detection box 1 to be plugged into the mobile socket 12.

[0033] like Figure 5 As shown, the observation platform 3 is a quadrangular structure as a whole, and an observation mirror 10 is fixedly installed at the end of the observation platform 3. The special shape of the observation platform 3 can reduce the amount of light entering the interior of the detection box 1 from the observation mirror 10. At the same time, the observation mirror 10 is a specially treated monochrome glass, which can maintain a dark environment inside the detection box 1 when in use, so that the user can observe the bad pixels and light leakage of the liquid crystal detection panel.

[0034] The working principle of the utility model is as follows: when in use, the liquid crystal display panel assembled with the frame is clamped and fixed at its upper and lower ends by two sets of telescopic clamping rods 8, wherein the two sets of telescopic clamping rods 8 are telescopic, and the connecting rods 9 fixedly connected between the two sets of telescopic clamping rods 8 can clamp and fix liquid crystal display panels of different sizes. Then, the two moving frames 6 drive the clamped liquid crystal display panel to slide on the sliding frame 5. When the moving frame 6 slides to the top of the docking rail 15, the bottom surface of the moving frame 6 contacts the upper end surface of the docking rail 15. At this time, the sliding portion on the moving frame 6 is in contact with the upper end surface of the docking rail 15. The folding curtain 14 can slide downward and drive the clamped LCD panel to move into the interior of the detection box 1. When the LCD panel is completely moved into the interior of the detection box 1, the user closes the flip cover 2, and at the same time takes out the connecting wire on the back of the LCD panel through the through groove opened through the outer wall of the detection box 1 and plugs it into the mobile socket 12. Then the user pulls the two folding curtains 14 to block the through groove, and finally cooperates with the external program control to play a pure color picture on the LCD panel, and the light leakage and bad pixels on the LCD panel in the detection box 1 can be observed at the observation mirror 10.
