DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 and Figure 2 As shown, a correction device applied to an LCD liquid crystal screen module includes a shell 1, a plurality of support legs 2 are fixedly connected to the lower end of the shell 1, a control box 7 is fixedly installed at the front end of the shell 1, a support plate 3 is fixedly connected to the rear end of the shell 1, a brightness distribution correction mechanism 4 is fixedly installed at the lower end of the support plate 3, a driving and rotating component 5 is jointly provided in the inner cavity and the upper end of the shell 1, and a cleaning component 6 is provided at the upper left part of the shell 1.

[0034] During the implementation of this embodiment, the front side of the LCD screen module is placed in the pushing and rotating component 5. By operating the control box 7, the pushing and rotating component 5 drives the LCD screen module to move to the right, and automatically clamps and adsorbs the LCD screen module during the movement. At the same time, the dust and fingerprints on the outer surface of the display on the LCD screen module are cleaned by the cleaning component 6 during the movement. After moving to the set position, the LCD screen module is evenly pushed and rotated by the pushing and rotating component 5, so that the brightness distribution correction mechanism 4 can perform a comprehensive brightness distribution correction operation on the display surface of the LCD screen module.

[0035] The control box 7 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its internal structure, principle and connection method are not further explained.

[0036] The brightness distribution correction mechanism 4 mentioned above is composed of a photometer and a brightness probe in the prior art. In this solution, it is used to correct the brightness distribution of the LCD liquid crystal screen module, and its specific internal structure, connection method and principle are not further explained.

[0037] Specifically, in order to achieve uniform pushing and rotation of the LCD screen module, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the pushing and rotating component 5 includes two rectangular holes 51 symmetrically opened on the inner surface of the shell 1, and a conveying mechanism 52 is commonly provided on the inner surface of the two rectangular holes 51. A pushing mechanism 53 is provided at the upper end of the conveying mechanism 52, and an adsorption mechanism 54 is provided at the upper end of the pushing mechanism 53. A clamping mechanism 55 is symmetrically provided on one side of the upper inner surface of the shell 1 close to each other.

[0038] For further information, see Figure 4 and Figure 5 In this embodiment, the conveying mechanism 52 includes two rotating rods 521 rotatably connected to the inner surface of the outer shell 1, and the outer surfaces of the two rotating rods 521 are symmetrically fixedly connected with rollers 522 at the front and rear. The outer surfaces of the rollers 522 on the same side are commonly wound and connected with a conveyor belt 523. The rear end of the left rotating rod 521 is fixedly connected to a double-axis motor 524 fixedly connected to the rear end of the outer shell 1, and the rear end output end of the double-axis motor 524 is fixedly connected to a rotating rod 2 525 through a coupling, and the upper left ends of the two conveyor belts 523 are fixedly connected to a connecting block 526.

[0039] For further information, see Figure 3 , Figure 4 , Figure 8 and Fig. 9In this embodiment, the clamping mechanism 55 includes two extrusion plates 551 fixedly connected to the upper part of the inner surface of the shell 1 on one side close to each other, and the left part of the inner surface of the shell 1 on the side away from each other is provided with a limiting groove 552, and the inner surfaces of the two limiting grooves 552 are slidably connected to the limiting blocks 553, and the inner surfaces of the two limiting blocks 553 are fixedly connected with connecting rods 554, and the upper ends of the two connecting rods 554 are fixedly connected with spring telescopic rods 555, and the upper part of the inner surface of the shell 1 on one side close to each other is provided with a guide hole 559, and the two spring telescopic rods 559 are fixedly connected to the upper part of the inner surface of the shell 1 on one side close to each other. The upper ends of the two connecting rods 554 are fixedly connected with round rod plates 556 that slide with the inner surface of the guide hole 559, the inner surfaces of the two round rod plates 556 are slidably connected with round rod clamping plates 557, the outer surfaces of the two round rod clamping plates 557 are sleeved with return springs 558, the two ends of the two return springs 558 are respectively fixedly connected with one end of the round rod plate 556 and the semicircular block on the round rod clamping plate 557, the ends of the two connecting rods 554 that are close to each other are fixedly connected with iron blocks 5510, and the ends of the two conveyor belts 523 that are away from each other are fixedly connected with electromagnetic blocks 5511.

[0040] During the implementation process, the LCD screen module is placed between the two round rod clamping plates 557, and finally the front end output end of the dual-axis motor 524 is started to drive the rotating rod 1 521 located on the left to rotate through the coupling, and the conveyor belt 523 is rotated under the action of the winding connection, and the electromagnetic block 5511 is started. Under the action of the electromagnetic block 5511, it is magnetically attracted to the iron block 5510, and then the limit block 553 is driven to slide on the inner surface of the limit groove 552, so that the connecting rod 554 can stably drive the two round rod clamping plates 557 to move to the right, and the semicircular blocks on the round rod clamping plates 557 are squeezed by the squeezing plate 2 551, so that the two round rod clamps The holding plates 557 move toward each other to the middle to clamp and fix the LCD screen module. When they move to the intersection of the guide holes 559, the height of the upper inner surface of the guide holes 559 drops, causing the round rod plate 556 to be squeezed and the spring telescopic rod 555 to be in a compressed state, and then the two round rod clamping plates 557 are driven to move downward, so that the height of the fixed LCD screen module will also drop, which can ensure the stability and accuracy of the LCD screen module before correction. The stable clamping and conveying can prevent the module from being displaced or tilted during movement or correction, thereby affecting the accuracy and effect of correction, and helping to obtain more accurate correction results.

[0041] Secondly, in the process of continuing to move to the right, when the limit block 553 moves to the right part of the inner surface of the limit groove 552, the electromagnetic block 5511 is closed, so that the electromagnetic block 5511 is away from the iron block 5510, and the two round rod clamping plates 557 no longer move to the right.

[0042] The electromagnetic block 5511 in the above figure is a mature electromagnetic technical means and equipment in the prior art. In this solution, it is used to generate magnetic force after being energized to perform magnetic attraction operation on the iron block 5510, and its internal structure, connection method and principle are not further explained.

[0043] For further information, see Figure 4 and Figure 7 In this embodiment, the adsorption mechanism 54 includes a fixed plate 541 which is fixedly connected to one end of the two conveyor belts 523 close to each other, a circular groove plate 542 is fixedly connected to the lower end of the fixed plate 541, a piston rod 543 is slidably connected to the inner surface of the circular groove plate 542, a pulley 545 is fixedly connected to the front end of the piston rod 543, a return spring 2 544 is sleeved on the outer surface of the piston rod 543, and the two ends of the return spring 2 544 are respectively fixedly connected to the piston on the piston rod 543 and the rear part of the inner surface of the circular groove plate 542, an extrusion plate 1 546 which is closely attached to the outer surface of the pulley 545 is fixedly connected to the lower side of the front part of the inner surface of the shell 1, a hollow block 547 is fixedly connected to the upper end of the push block 534, an adsorption disk 548 is rotatably connected to the inner surface of the hollow block 547, and the inner cavity of the hollow block 547 is connected to the inner cavity of the circular groove plate 542 through a hose.

[0044] During the implementation process, the two round rod clamping plates 557 move downward, so that the height of the fixed LCD screen module will also decrease, and the lower end of the LCD screen module will squeeze the silicone suction cup on the adsorption plate 548. At the same time, the movement of the conveyor belt 523 will drive the fixed plate 541 to move to the right, so that the pulley 545 is squeezed by the squeezing plate 546 and gradually pushes the piston rod 543 to move backward on the inner surface of the circular groove plate 542, so that the piston on the piston rod 543 extracts the air in the inner cavity of the silicone suction cup through the hose, and the clamping fixation method is converted into the adsorption fixation method. The suction cup adsorption fixation method can distribute the adsorption force more evenly, so that the module remains stable during the calibration process, improves the calibration accuracy, and is more convenient for subsequent operations.

[0045] For further information, see Figure 3 , Figure 4 and Figure 6 In this embodiment, the pushing mechanism 53 includes a slide plate 531 fixedly connected to the upper ends of the two connecting blocks 526, a return spring 532 is fixedly connected to the front of the inner surface of the slide plate 531, a slider 533 slidably connected to the inner surface of the slide plate 531 is fixedly connected to the rear end of the return spring 532, a push block 534 is fixedly connected to the upper end of the slider 533, and an electric cylinder 535 is fixedly installed on the middle side of the front inner surface of the shell 1.

[0046] For further information, see Figure 3 and Figure 7In this embodiment, a gear 549 is fixedly connected to the outer surface of the adsorption plate 548, and a rack 5410 meshing with the gear 549 is fixedly connected to the left part of the inner surface of the shell 1.

[0047] As can be seen from the above, when the fixed LCD liquid crystal screen module moves to the set position, the electric cylinder 535 is started at this time, so that the electric cylinder 535 extends out of the inner cavity of the shell 1, and at the same time, the rear end of the electric cylinder 535 can be close to the front end of the push block 534, and the electric cylinder 535 can evenly push the push block 534, so that the slider 533 slides on the inner surface of the slide plate 531 to put the reset spring 1 532 in a stretched state. When the gear 549 on the adsorption plate 548 is engaged with the rack 5410, the gear 549 will drive the adsorption plate 548 to rotate on the inner surface of the hollow block 547, and then the LCD liquid crystal screen module can be driven to rotate in the process of uniform pushing, and it can be evenly pushed and rotated in the same horizontal plane. First, the uniform push ensures that the LCD screen module can be fully and completely illuminated by the light source. Every pixel on the LCD screen module can receive the same or similar lighting conditions, which provides a solid foundation for the subsequent brightness distribution evaluation and adjustment. Secondly, rotating the module in the same horizontal plane enriches the diversity of correction angles. Not only can the module be carefully examined from multiple perspectives, but it can also effectively avoid correction blind spots caused by lighting shadows or reflection problems at specific angles. The comprehensiveness and accuracy of the correction have been significantly improved, making the final LCD screen module brightness distribution more uniform and consistent, thereby improving the product display quality and user experience.

[0048] The rotational connection between the hollow block 547 and the adsorption disk 548 described above has a certain resistance, that is, the adsorption disk 548 can rotate on the inner surface of the hollow block 547 only after the gear 549 and the rack 5410 are engaged.

[0049] Embodiment 2: Based on Embodiment 1, this embodiment adds a cleaning component 6 for cleaning dust and fingerprints on the outer surface of the LCD screen module before brightness distribution detection and correction is performed, so as to achieve the purpose of cleaning dust and fingerprints on the outer surface of the LCD screen module before brightness distribution detection and correction is performed.

[0050] Specifically, in order to clean the dust and fingerprints on the outer surface of the LCD screen module before performing brightness distribution detection and calibration, refer to Figure 4 , Fig.10 and Fig.11 In this embodiment, the cleaning component 6 includes a concave plate 61 fixedly connected to the upper left portion of the housing 1, a cleaning mechanism 62 is provided on the inner surface of the concave plate 61, and a wiping mechanism 63 is provided on the upper right side of the inner surface of the concave plate 61.

[0051] For further information, see Figure 4 and Fig.10 In this embodiment, the cleaning mechanism 62 includes a round hole rod 621 fixedly connected to the inner surface of the concave plate 61, a sponge block 624 is fixedly connected to the outer surface of the round hole rod 621, a placement box 623 is fixedly connected to the upper end of the concave plate 61, the left part of the inner surface of the placement box 623 penetrates and extends to the inner surface of the round hole rod 621 and is fixedly connected to a connecting pipe 625 rotatably connected to the round hole rod 621, and a pulley group 622 is fixedly connected to the rear part of the outer surface of the round hole rod 621 and the outer surface of the rotating rod 255.

[0052] For further information, see Figure 4 and Fig.11 In this embodiment, the wiping mechanism 63 includes two spring telescopic rods 631 symmetrically fixedly connected to the upper inner surface of the concave plate 61 in a front-to-back manner. The lower ends of the two spring telescopic rods 631 are fixedly connected to a connecting plate 632, and the lower end of the connecting plate 632 is attached with a wiping cloth 633 by Velcro.

[0053] During the implementation process, after the LCD screen module is adsorbed and fixed, in the process of moving to the right, the rear end output end of the dual-axis motor 524 is started to drive the rotating rod 525 to rotate through the coupling, and the sponge block 624 on the round hole rod 621 is driven to rotate under the transmission action of the pulley group 622, and the cleaning liquid in the placement box 623 is introduced into the sponge block 624 through the connecting pipe 625, so that the sponge block 624 can clean the dust and fingerprints attached to the outer surface of the LCD screen module during the rotation process. At the same time, when the LCD screen module moves to the right afterwards, the wiping cloth 633 is tightly attached to the outer surface of the LCD screen module under the action of the spring telescopic rod 631, and the residual cleaning liquid is cleaned, so that the light source can directly irradiate the module surface accurately and unhindered during the calibration process, so as to truly reflect the brightness distribution of the module itself, avoid light scattering and reflection interference caused by dust or fingerprints, and thus improve the accuracy and reliability of the calibration result.

[0054] The dual-axis motor 524 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, the couplings on both sides thereof can rotate independently and can stop after rotating to a set number of circles. Its internal structure, connection method and principle will not be elaborated any more.

[0055] The electric cylinder 535 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, its retractable function is utilized, and its internal structure, connection method and principle are not further explained.

[0056] Working process: When in use, the LCD screen module is initially fixed by the cooperation of the conveying mechanism 52 and the clamping mechanism 55 to improve the accuracy and limit of the placement of the LCD screen module. Then, the LCD screen module is adsorbed and fixed by the adsorption mechanism 54. When the LCD screen module moves to the right, the dust and fingerprints on the outer surface of the LCD screen module are effectively cleaned by the cooperation of the cleaning mechanism 62 and the wiping mechanism 63. Then, the LCD screen module is evenly pushed by the pushing mechanism 53, and the LCD screen module is rotated by the cooperation of the gear 549 and the rack 5410.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
