[0002] The LCD panel is the material that determines the brightness, contrast, color, and viewing angle of the LCD display. The price trend of the LCD panel directly affects the price of the LCD display. The quality and technology of the LCD panel are related to the overall performance of the LCD display.

[0003] Before assembling the shell of the LCD panel, the performance of the LCD panel needs to be tested, including light leakage detection, bad pixel detection, and detection of components on the back of the panel. During the detection process, the operator needs to fix the LCD panel at a certain tilt angle or flip the back upward for easy operation. The LCD panel fixture in the prior art is difficult to tilt and flip the LCD panel after it is clamped and fixed. At the same time, it is not suitable for clamping both ordinary flat LCD panels and curved LCD panels, which has great limitations when used. To this end, we propose a fixture for LCD panel detection. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-5 As shown, a fixture for testing LCD liquid crystal panels includes a testing platform 1, support frames 2 are fixedly installed at both ends of the upper end surface of the testing platform 1, fixed slides 5 are movably installed at the upper ends of the opposite sides of the two support frames 2, and adjustment rods 7 are slidably installed at both ends of the fixed slides 5. A sliding clamp 8 is slidably installed at the end of the adjusting rod 7, and a clamping component 9 is movably connected inside the sliding clamp 8;

[0027] The clamping assembly 9 includes an adjusting shaft 902 rotatably connected to the sliding clamp 8, and two groups of symmetrically arranged steering shafts 903 are rotatably mounted on the outer wall of the adjusting shaft 902, and the outer walls of the two groups of steering shafts 903 are fixedly mounted with clamping plates 901;

[0028] The adjusting rods 7 arranged at both ends of the fixed slide 5 are adjusted according to the length and width of the liquid crystal panel to be detected. During the adjustment, the adjusting rods 7 slide on the fixed slide 5, and the sliding clamps 8 slide at the ends of the adjusting rods 7. When the four groups of sliding clamps 8 adjust the four corners of the liquid crystal panel respectively, the two groups of clamps 901 arranged inside the sliding clamps 8 are further adjusted according to the shape of the liquid crystal panel. When the two groups of clamps 901 are adjusted to a horizontal state, they can be used to clamp and fix ordinary flat liquid crystal panels. When the clamps 901 are adjusted to an inclined state, they can be used to clamp and fix the two ends of the curved liquid crystal panel.

[0029] like Figure 3 As shown, the outer walls of the two groups of steering shafts 903 are fixedly installed with driven gears 904, the outer wall of the sliding clamp 8 is located between the two driven gears 904 and is rotatably installed with a driving wheel 905, and the driving wheel 905 is meshed and connected with the two driven gears 904. When the driving wheel 905 rotates, the driving wheel 905 can drive the two driven gears 904 to rotate, and the driven gears 904 are fixedly connected to the steering shaft 903. When the driven gear 904 rotates, the steering shaft 903 and the clamping plate 901 fixedly connected to its outside move synchronously, and the two groups of clamping plates 901 are opened to both sides respectively, which is convenient for clamping the four corners of the liquid crystal panel.

[0030] like Figure 5 As shown, a rotating shaft 6 is fixedly installed at the center position of the outer wall of the fixed slide 5, and the fixed slide 5 is rotatably connected to the center position of the upper end of the support frame 2 through the rotating shaft 6. The fixed slide 5 can rotate around the rotating shaft 6. When rotating, the fixed slide 5 can drive the clamped liquid crystal panel to tilt or flip, thereby facilitating the operator to detect the front and back panels of the liquid crystal panel.

[0031] As shown in the inspection table 1, rubber pads are provided on the outer walls of the opposite sides of the two sets of clamps 901, and the rubber pads are glued to the outer walls of the clamps 901. The provision of the rubber pads can transform the hard contact between the clamps 901 and the four corners of the liquid crystal panel into flexible contact, thereby avoiding damage to the liquid crystal panel when the two sets of clamps 901 clamp the four corners of the liquid crystal panel.

[0032] like Figure 4As shown, a blocking block 10 is fixedly installed on the upper end surface of the sliding clamp 8, and the cross-section of the blocking block 10 is L-shaped. The L-shaped blocking block 10 can be used in conjunction with the clamp 901. When the four corners of the liquid crystal panel are overlapped and placed above the clamp 901 without flipping the liquid crystal panel, the liquid crystal panel can be fixed under the blocking effect of the blocking block 10, which is used to quickly fix the liquid crystal panel in different situations, thereby saving the inspection time of large quantities of liquid crystal display panels.

[0033] like Figure 1 As shown, a lifting platform 3 is movably installed at the center of the upper end surface of the testing platform 1, and a supporting block 4 is fixedly installed at the telescopic end of the lifting platform 3;

[0034] The support block 4 is flexibly arranged. When the telescopic end of the lifting platform 3 is extended, the support block 4 arranged at the telescopic end of the lifting platform 3 can support the liquid crystal panel.

[0035] like Figure 1 As shown, a clearance cavity is opened at the upper end surface of the detection platform 1 and the corresponding position of the lifting platform 3, and an electric telescopic rod is fixedly installed inside the clearance cavity, and the output end of the electric telescopic rod is fixedly connected to the bottom surface of the lifting platform 3; after the four groups of sliding clamps 8 clamp and fix the four corners of the liquid crystal panel, the electric telescopic rod inside the clearance cavity contracts so that the lifting platform 3 and the support block 4 are stored in the clearance cavity, thereby avoiding affecting the fixed slide 5 to drive the clamped liquid crystal panel to tilt or flip for testing.

[0036] The working principle of the utility model is as follows: when in use, the manipulator clamps the liquid crystal panel to be tested and places it above the testing platform 1, the lifting platform 3 arranged on the upper end surface of the testing platform 1 is extended, and the support block 4 arranged at the end of the lifting platform 3 supports the liquid crystal panel, then, the adjusting rods 7 arranged at both ends of the fixed slide 5 are adjusted according to the length and width of the liquid crystal panel to be tested, during the adjustment, the adjusting rod 7 slides on the fixed slide 5, and the sliding clamp 8 slides at the end of the adjusting rod 7, when the four groups of sliding clamps 8 adjust the four corners of the liquid crystal panel respectively, the output end of the lifting platform 3 is shortened so that the support block 4 supporting the liquid crystal panel descends, when the liquid crystal panel to be tested is an ordinary flat liquid crystal panel, the four groups of sliding clamps 8 can directly fix the four corners of the ordinary liquid crystal panel, at this time, the clamping plate 901 arranged inside the sliding clamp 8 is in a horizontal state, The four corners of an ordinary flat liquid crystal panel can be overlapped on the upper surface of the clamping plate 901 for support, or can be clamped inside the two clamping plates 901 for fixation. When the curved liquid crystal panel to be detected is a curved liquid crystal panel, the two groups of clamping plates 901 arranged inside the sliding clamp 8 can be adjusted to be tilted according to the shape of the end of the curved liquid crystal panel. Under the driving effect of the rotation of the adjustment shaft 902, the two groups of clamping plates 901 can be rotated to be tilted, and then the driving wheel 905 rotates to drive the two driven gears 904 to open and clamp and fix the four corners of the two ends of the curved liquid crystal panel. After the two ends of the ordinary flat liquid crystal panel and the curved liquid crystal panel are clamped and fixed, the fixed slide 5 rotates with the rotating shaft 6 as the axis, and the clamped and fixed liquid crystal panel can be adjusted to be tilted or flipped so that its back is facing up, thereby facilitating the use of the liquid crystal panel for detection by the staff.
