Description

Technical Field

[0001] The invention relates to the technical field of display screen detection, in particular to an LCD display screen detection device. Background Art

[0002] LCD screens need to be tested for their own strength during production. To ensure that the products leaving the factory can be fully tested, we have previously proposed a notice numbered CN110596923B, with the subject name being a pressure-resistant testing device for LCD screen production. While achieving continuous feeding of the screen, it also provides stable conditions for the pressing operation of the screen, and can also test large batches of screens in sequence, with the advantage of high testing efficiency, avoiding the flow of untested screens into the market and improving the production quality of the screen.

[0003] However, through after-sales maintenance data, we found that the display screen may be accidentally damaged during transportation or use. For example, during transportation, the glass structure in the middle of the display screen may be squeezed by other goods, which may easily cause it to separate from the edge seal and damage the seal. Alternatively, the display screen may fall and be damaged when it is installed. Although this phenomenon is difficult to avoid, we believe that simulation tests can be conducted on the above complex usage and transportation environments, and targeted improvements can be made based on the test results of the easily damaged parts. However, common detection devices are difficult to simulate and detect multiple situations, which makes it difficult to obtain comprehensive test results. Summary of the invention

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Fig.10 The present invention provides a technical solution: an LCD display screen detection device, comprising a detection platform 1, a fixed high pole 11 and a fixed plate 12, wherein the number of the fixed high poles 11 is two, and they are fixedly installed on both sides of the upper surface of the detection platform 1, respectively, and the fixed plate 12 is fixedly installed on one side of the fixed high pole 11, and a cleaning component is arranged on the fixed high pole 11, and the cleaning component comprises a suspended module and a cleaning module, and the suspended module and the cleaning module cooperate with each other to improve the accuracy of the detection result;

[0038] The suspended module includes a first transmission wheel 2, which is movably mounted on the surface of the fixed high pole 11, a second transmission wheel 21 is movably mounted on the surface of the fixed plate 12, mounting plates 22 are fixedly mounted on both sides of the upper surface of the detection platform 1, a driving disk 23 is mounted on the surface of the mounting plate 22, a tightening wheel 25 is fixedly mounted on the output shaft of the driving disk 23, a suspension rope 26 is fixedly connected to the outer surface of the tightening wheel 25, and an end of the suspension rope 26 away from the tightening wheel 25 is fixedly connected to an adjusting member 27 through the second transmission wheel 21 and the first transmission wheel 2;

[0039] An adjusting slot 28 is provided in the middle of the adjusting member 27, and adjusting studs 29 are provided on both the upper and lower sides of the adjusting slot 28. A clamping plate 210 is fixedly installed on one end of the adjusting stud 29, and an adjusting nut 211 is threadedly connected to the outer surface of the adjusting stud 29. There are two adjusting nuts 211, which are respectively located on both sides of the adjusting member 27, and a display screen 212 is provided between the two clamping plates 210.

[0040] The cleaning module includes a servo motor 213 fixedly mounted on the bottom of the detection platform 1, a rotating rod 214 is fixedly mounted on the output shaft of the servo motor 213, a brush body 215 is fixedly sleeved on the lower side of the outer surface of the rotating rod 214, and bristles 216 are fixedly connected to the inner side of the brush body 215;

[0041] A lead screw 217 is fixedly installed on the top of the rotating rod 214, a fixing frame 218 is movably installed on the top of the lead screw 217, the bottom of the fixing frame 218 is fixedly installed on the upper surface of the detection platform 1, a protective member 219 is spirally connected to the outer surface of the lead screw 217, a first slider 220 is fixedly installed on both sides of the protective member 219, and a first slide groove 221 adapted to the first slider 220 is opened on both sides of the fixing frame 218;

[0042] A camera 222 is fixedly mounted on the upper side of the outer surface of the rotating rod 214, and the protective member 219 is initially located outside the camera 222;

[0043] The edge of the outer surface of the driving disc 23 is threadedly connected with a limiting bolt 24, and the length of the limiting bolt 24 is greater than the distance between the driving disc 23 and the mounting plate 22;

[0044] The brush body 215 is made of rubber, the clamping plate 210 is made of aluminum alloy, and a rubber pad is provided on a side close to the positioning member 311 .

[0045] Specifically, when in use, the user first needs to place the middle parts of both sides of the display screen 212 between the two clamping plates 210, and then adjust the two adjusting studs 29 so that the two clamping plates 210 clamp the display screen 212, and then tighten the adjusting nuts 211 so that the two adjusting nuts 211 are tightly connected to the adjusting member 27, and the adjusting studs 29 are positioned by using the friction between the adjusting nuts 211 and the adjusting member 27, so that the display screen 212 is clamped;

[0046] After the display screen 212 is clamped, the driving disk 23 needs to be rotated so that the driving disk 23 drives the tightening wheel 25 to rotate, thereby tightening the hanging rope 26. When the hanging ropes 26 on both sides are tightened to the same length, the display screen 212 will be pulled by the hanging rope 26 and move upward. When the display screen 212 moves upward to the height of the brush body 215, the driving disk 23 is stopped from rotating, and the limiting bolt 24 is tightened so that the limiting bolt 24 is in close contact with the mounting plate 22. The friction between the limiting bolt 24 and the mounting plate 22 is used to position the tightening wheel 25 to prevent the tightening wheel 25 from reversing.

[0047] When the display screen 212 moves upward and is suspended in the air, the servo motor 213 needs to be started to drive the rotating rod 214 to rotate two to three times. At this time, the brush body 215 will rotate with the rotating rod 214, so that the bristles 216 clean the upper and lower sides of the display screen 212, which can prevent dust or foreign matter from adhering to the surface of the display screen 212, further damaging the display screen 212 under the action of pressure, and affecting the accuracy of the pressure resistance test result. It should be noted that before cleaning, the positioning member 311 needs to be placed on the front side of the display screen 212 to position the display screen 212 to avoid the friction generated by cleaning causing the display screen 212 to shake. In addition, the brush body 215 needs to be made of a deformable material such as rubber, so that the brush body 215 can clean the display screen 212 by deforming over the hanging rope 26;

[0048] Furthermore, after the rotation is completed, the test piece 319 needs to be located directly above the display screen 212. During this process, the lead screw 217 will rotate with the rotating rod 214. When the lead screw 217 rotates, the protective piece 219 will be driven to move the protective piece 219 upward, thereby revealing the camera 222. The camera 222 can be used to monitor the deformation state of the display screen 212 during the compression test to improve the comprehensiveness of the test data. When the camera 222 is not in operation, the protective piece 219 protects it to prevent it from being damaged or the camera from being unclear due to dust, resulting in inaccurate test results.

[0049] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , a pressure resistance detection component is provided on the detection platform 1, and the pressure resistance detection component includes a pressure supply module and a limit module;

[0050] The pressure supply module includes a fixing frame 3 fixedly installed at the bottom of the detection platform 1, a bidirectional hydraulic rod 31 is fixedly installed on the inner side of the fixing frame 3, a first fixing member 32 is fixedly installed on the output shaft of the bidirectional hydraulic rod 31, a second fixing member 33 is arranged on one side of the first fixing member 32, a thread groove is provided on the surface of the first fixing member 32 and the second fixing member 33, a fastening bolt 34 is threadedly connected in the thread groove, and the first fixing member 32 and the second fixing member 33 are fixedly connected by the fastening bolt 34;

[0051] A guide column 35 is fixedly installed on the inner side of the fixing frame 3, the first fixing member 32 and the second fixing member 33 are movably installed on the outer surface of the guide column 35, the first connecting member 36 is fixedly installed on the upper surface of the second fixing member 33, a top rod 37 is movably installed on the inner side of the first connecting member 36, a second connecting member 38 is movably installed on the end of the top rod 37 away from the first connecting member 36, a bearing plate 39 is fixedly installed on the top of the second connecting member 38, a magnetic suction plate is arranged inside the bearing plate 39, an extrusion member 310 is arranged in the middle of the upper surface of the bearing plate 39, and a positioning member 311 is arranged at the edge of the upper surface of the bearing plate 39;

[0052] The two sides of the bottom of the test platform 1 are fixedly installed with limit members 312, and the cross-section of the limit member 312 is L-shaped. The bottom of the bearing plate 39 is located inside the limit member 312, and the upper side of the outer surface of the rotating rod 214 is fixedly sleeved with a test piece 319. The center of the extrusion member 310 after placement is on the same straight line as the center of the test piece 319.

[0053] The limit module includes a gear 313, which is fixedly mounted in the middle of the contraction wheel 25, a rack 314 is meshed below the gear 313, one end of the rack 314 is threadedly connected to a connecting stud 316, and one end of the connecting stud 316 away from the rack 314 is fixedly connected to an anti-deflection member 317;

[0054] A second slider 315 is fixedly mounted on the bottom of the rack 314, and the second slider 315 is T-shaped. A second slide groove 318 matching the second slider 315 is provided on the upper surface of the detection platform 1.

[0055] A pressure sensor is disposed inside the test piece 319 , and the test piece 319 and the brush body 215 are disposed at an interval of ninety degrees about the center of the rotating rod 214 .

[0056] On the basis of Example 1, when the cleaning operation is completed, it is necessary to continue to rotate the driving disk 23 to drive the hanging rope 26 to be tightened until the upper surface of the display screen 212 contacts the bottom of the test piece 319, so that the influence of the weight of the display screen 212 on the test result can be avoided during the compression test;

[0057] When the driving disk 23 rotates, the focusing wheel 25 is driven to rotate, thereby enabling the gear 313 to rotate. The gear 313 can be used to drive the rack 314, so that the rack 314 drives the anti-bias member 317 to move. When the display screen 212 contacts the test piece 319, the anti-bias member 317 is also in contact with the side of the display screen 212. In this way, the display screen 212 can be limited, thereby improving the stability of the display screen 212 during pressure resistance testing, thereby further improving the accuracy of the test results. It should be noted that the driving disk 23 on the left side needs to rotate counterclockwise, and the driving disk 23 on the right side needs to rotate clockwise, so as to ensure that the anti-bias members 317 are close to each other.

[0058] When the limiting operation is completed, it is necessary to start the bidirectional hydraulic rod 31 to drive the first fixing member 32 to move, and the first fixing member 32 can drive the second fixing member 33 to move, so that the top rod 37 can lift the supporting plate 39, and after the extrusion member 310 is in contact with the display screen 212, pressure is continuously provided to the display screen 212 until the pressure value reaches the standard, and the pressure data is transmitted to the detection system through the pressure sensor inside the test piece 319. With the image transmitted by the camera 222, the deformation state of the display screen 212 under the pressure change can be clearly seen throughout the detection process. In addition, by using extrusion members 310 with different deformations or diameters, the influence of the pressure resistance detection factor on the display screen 212 can be tested.

[0059] Example 3: Please refer to Figures 1 to 10, a simulation component is provided on the anti-deflection member 317, and the simulation component includes a positioning pin 4 fixedly installed at the bottom of the anti-deflection member 317, and a driving groove 41 adapted to the positioning pin 4 is provided on both sides of the detection platform 1, and a pin hole 42 adapted to the positioning pin 4 is provided on the upper surface of the first fixing member 32;

[0060] A boost bolt 43 is threadedly connected to the middle of the anti-deviation piece 317 . The length of the boost bolt 43 is greater than the height of the anti-deviation piece 317 . A grinding head 44 is fixedly installed at the bottom of the boost bolt 43 .

[0061] On the basis of Example 2, when the pressure resistance test of the display screen 212 is completed, it is necessary to change the operation mode of the device to simulate different conditions of the display screen 212;

[0062] First, to simulate the display screen 212 falling from a high place, the test piece 319 and the brush body 215 need to be reset to the initial state to avoid interference with the simulation process. In addition, the protective piece 219 is used to protect the camera 222 again to prevent the glass of the display screen 212 from breaking and splashing onto the camera 222 after the display screen 212 falls, thereby damaging the camera 222.

[0063] After the test piece 319 is reset to the initial state, the support plate 39 needs to be reset to the initial state, and then the driving disk 23 is continuously rotated so that the suspension rope 26 continuously drives the display screen 212 to rise. When the display screen 212 rises to the moving height, the driving disk 23 is loosened so that the display screen 212 falls freely, thereby simulating the process of the display screen 212 falling from different heights. During the simulation process, the falling angle of the display screen 212 can be changed by the different contraction lengths of the suspension ropes 26 on both sides, thereby simulating different falling angles. It is also possible to set obstacles on the surface of the support plate 39 to simulate the process of the display screen 212 colliding with an object after falling.

[0064] Secondly, to simulate the display screen 212 being squeezed by other objects during transportation, before operation, the display screen 212 needs to be removed from the clamping plate 210, and then the display screen 212 needs to be placed in the middle of the upper surface of the bearing plate 39, and then the anti-deflection member 317 needs to be removed from the rack 314, and the positioning pin 4 needs to be inserted into the pin hole 42 through the driving groove 41, and then the rack 314 needs to be loosened to contact the fixation between the first fixing member 32 and the second fixing member 33;

[0065] When the fixing relationship between the first fixing member 32 and the second fixing member 33 is released, the bidirectional hydraulic rod 31 needs to be started to drive the first fixing member 32 to move. Since the positioning pin 4 is inside the first fixing member 32, when the first fixing member 32 moves, the positioning pin 4 will be driven to move, so that the positioning pin 4 drives the anti-deflection member 317 to move. The movement of the anti-deflection member 317 can be used to squeeze the display screen 212, thereby simulating the state of the display screen 212 being squeezed during transportation;

[0066] Third, to simulate the friction on the surface of the display screen 212, the anti-deflection member 317 needs to be placed above the display screen 212 before operation, and then the two-way hydraulic rod 31 is started to drive the first fixing member 32 to move to the position of the positioning pin 4, and the positioning pin 4 is inserted into the pin hole 42, and then the booster bolt 43 is turned to drive the grinding head 44 to move downward, so that the grinding head 44 contacts the display screen 212, and then the two-way hydraulic rod 31 is started again to drive the anti-deflection member 317 to move, so that the state of the display screen 212 being worn can be simulated;

[0067] After the above-mentioned simulations, the state of the damaged parts of the display screen 212 after common damage modes can be obtained, so that targeted improvements and optimizations can be made to the vulnerable parts to improve product quality. In addition, after the product is optimized and improved, the device can also be used to perform inspections to observe whether the production quality is qualified.
