[0034] A device and method for detecting a picture of a liquid crystal display screen, comprising the following steps: S1: Display screen installation. First, place the LCD screen to be tested on the middle of the upper end of the support plate 51. At this time, the motor 52 provided at the middle of the side of the support plate 51 can be driven to rotate the screw 53 provided inside the support plate 51. When the screw 53 rotates, the first clamp 54 and the second clamp 55, which are threadedly connected to the left and right sides of the screw 53, move relatively close to each other, and thus the LCD screen can be clamped and fixedly matched. When the straight-screen LCD screen is placed and clamped firmly, the three first pressure wheels 544 provided inside the first clamp 54 will simultaneously contact with one side of the straight-screen LCD screen. At the same time, the three first pressure wheels 544 will synchronously squeeze the three first connecting plates 543 installed correspondingly, so that the three first connecting plates 543 cooperate with the limiting strips 542 provided outside to limit and move to the side of the supporting plate 541. In this way, the first compression spring 546 installed on the outside of the first connecting rod 545 can be compressed, and the first compression spring 546 can cooperate with the elasticity of the first compression spring 546 to release the pressure. The first connecting plate 543 can be pushed outward as a whole. In this way, the three first pressing wheels 544 will cooperate with the three first connecting plates 543 to push outward synchronously to achieve efficient clamping and supporting cooperation on the outer end of one side of the straight-screen LCD screen. At the same time, the second pressing wheel 552 provided inside the second clamp 55 will contact with the other side of the straight-screen LCD screen to efficiently cooperate with the three first pressing wheels 544 to firmly clamp the straight-screen LCD screen and ensure the stability of its vertical placement state, so that the subsequent picture detection and shooting are clear and complete. When the placement test of the curved liquid crystal display screen is being performed, the three first pressure rollers 544 provided inside the first fixture 54 will again be in contact with one side of the curved liquid crystal display screen with the transmission. At this time, the first pressure rollers 544 on both sides, when in contact with the curved liquid crystal display screen, realize a long-distance push of the corresponding first connecting plates 543, so that the first compression springs 546 installed corresponding to the first connecting plates 543 on both sides can perform a large compression activity, thereby making the first connecting plates 543 on both sides stably against the corresponding first pressure rollers 544, so that the first pressure rollers 544 on both sides can effectively press the one side of the curved liquid crystal display screen. The clamping state on one side is flexible and adjustable. At the same time, the second pressure wheel 552 inside the second clamp 55 pushes the second connecting plate 551 when it contacts with the other side of the curved liquid crystal display screen, so that the connecting shafts 553 on both sides of the upper end of the second connecting plate 551 move synchronously, and the connecting shafts 553 on both sides move downward, and the connecting shafts 553 on both sides are connected to the second connecting plate 551. The transmission plates 554 at the outer ends of the connecting shafts 553 on both sides realize synchronous relative swinging activities, thereby correspondingly driving the pressure strips 555 connected to the lower ends of the transmission plates 554 on both sides to rotate synchronously, so that the pressure strips 555 on both sides are clamped against the other side of the curved liquid crystal display screen. Since the pressure strips 555 on both sides are in an inner clamping state, when the pressure strips 555 on both sides are clamped against the other side of the curved liquid crystal display screen, a certain inward pressing force is provided to ensure that the second clamp 55 adapts to the shape of the other side of the curved liquid crystal display screen. At the same time, when the second pressure wheel 552 pushes the second connecting plate 551, the second connecting plate 552 can be 51 moves along the second connecting rod 557 installed inside the connecting frame 556, thereby squeezing the second compression spring 558 installed outside the second connecting rod 557, so that the second compression wheel 552 and the pressure strips 555 on both sides cooperate with the rebound force of the second compression spring 558 to stably clamp the other side of the curved liquid crystal display screen. Therefore, when the curved liquid crystal display screen is placed and tested, the first clamp 54 and the second clamp 55 can be adjusted and changed with the curved surface to realize flexible adjustment and change of the clamping state, so that when the curved liquid crystal display screen is placed and tested, there is no need to change the equipment to meet the needs of convenient clamping and placement testing; At the same time, in the subsequent picture detection shooting, in order to be able to shoot pictures in different directions of the LCD screen and avoid the occurrence of defects in the pictures in different directions, for this reason, when shooting pictures in different directions, the cylinder 566 connected to the middle of the first rack 5621 can be driven to make the first rack 5621 move along one side of the inner part of the support frame 561. When the first rack 5621 moves, the first gear 5622 set in the middle of the outer end of the transmission is driven to drive the first gear 5622 to realize the drive of the rotating shaft 5623 connected to the middle of the upper end. In this way, the first gear 5622 connected to the upper end of the rotating shaft 5623 is connected. The bevel gear 5624 will realize the meshing transmission between the second bevel gear 5625 and the third bevel gear 5626, so that the transmission rod 5627 installed in the middle of the upper end of the third bevel gear 5626 will realize the driving of the butt joint pipe 565 connected to the outer side of the upper end, so that the butt joint pipe 565 assists in realizing the rotation of the top connected support plate 51, so as to make the support plate 51 rotate along one side of the upper end of the frame 1, conveniently realize the display of the placed LCD screen in different directions, meet the shooting and recording of the LCD screen images in different directions, greatly improve the accuracy of LCD screen image detection, and reduce the occurrence of unqualified products; Secondly, when the height needs to be adjusted, the cylinder 566 connected to the middle part of the second rack 5631 needs to be driven to move the second rack 5631 along one side of the inside of the support frame 561. As the second rack 5631 moves, the second gear 5632 engaged with the middle part of the outer end of the second rack 5631 rotates accordingly, and synchronously realizes the rotation of the internally connected rotating seat 5633. When the rotating seat 5633 rotates, the lifting rod 5634 threadedly connected to the inside of the rotating seat 5633 is plugged into the matching limit shaft 564 provided at the lower end of the support frame 561. When the support plate 51 is lifted or lowered, the support plate 51 connected to the upper end of the lifting rod 5634 can be lifted or lowered accordingly, so as to flexibly adjust the height of the LCD screen for image detection and shooting. At the same time, when the support plate 51 is lifted or lowered, the butt joint pipe 565 connected to the middle part of the lower end of the support plate 51 will move with the transmission rod 5627 provided inside the first adjustment structure 562 to ensure that after the support plate 51 is lifted or lowered, the first adjustment structure 562 can still be connected to the butt joint pipe 565 to ensure the stability of the direction rotation adjustment effect. S2: Image data acquisition. After the LCD screen is conveniently clamped and placed firmly by the multifunctional stabilizing device 5, the staff can open the camera 4 provided on the upper end of the bracket 3 to make the camera 4 shoot the image state of the LCD screen. In this way, the acquisition of the image state of the LCD screen is greatly improved, and the occurrence of non-standard phenomenon of human observation is avoided. At the same time, the collected image data will be transmitted to the inside of the color analyzer body 2 to realize the comparative detection activity; S3: Image data analysis. The image data captured by the camera 4 will be imported into the color analyzer body 2. Before the image detection, the color analyzer body 2 will preset the standard image data.
