[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 3 As shown, a flatness detection device of this utility model includes: a carrier 5, which is connected to a plurality of locking blocks 51, the plurality of locking blocks 51 forming a positioning space, and the carrier 5 having a plurality of detection ports 54 corresponding to the positioning space; a first detection component 2, including a first driving mechanism and a first detection mechanism, the first detection mechanism being connected to the output end of the first driving mechanism, and the detection end of the first detection mechanism facing the positioning space; and a second detection component 3, including a second driving mechanism and a second detection mechanism, the second detection mechanism being connected to the output end of the second driving mechanism, the detection end of the second detection mechanism facing the detection port 54, and the carrier 5 being located between the first detection mechanism and the second detection mechanism.

[0026] In this embodiment, a flatness detection device places a display screen within the positioning space on a support member 5, with the edge of the display screen abutting against a locking block 51. A first driving mechanism then moves a first detection mechanism to perform flatness detection on one side of the display screen. Simultaneously, a second driving mechanism moves a second detection mechanism to perform flatness detection on the other side of the display screen through a detection port 54. The locking block 51 positions the display screen at the detection location. The detection port 54 on the support member 5 allows both the first and second detection mechanisms to simultaneously perform flatness detection on both sides of the display screen, thereby improving detection efficiency.

[0027] Reference Figure 5As shown, the support member 5 is plate-shaped and supports the display screen. Multiple locking blocks 51 are connected to the support member 5, forming a positioning space. The support member 5 has multiple detection ports 54 corresponding to the positioning space. Specifically, a positioning groove 52 is provided on the side of the locking block 51 near the positioning space. In this embodiment, four locking blocks 51 are connected to the support member 5. The positioning groove 52 of the locking block 51 is used to engage with the four corner edges of the mounting base around the display screen, thereby fixing the position of the display screen. The support member 5 also has a receiving groove 53. The detection ports 54 are located at the bottom of the receiving groove 53 and penetrate the support member 5. The cross-section of the detection ports 54 is rectangular. Adjacent detection ports 54 form support rods, making the bottom of the receiving groove 53 mesh-like and keeping the bottom of the receiving groove 53 horizontal. When the display screen is attached to the bottom of the receiving groove 53, the support rods can support the display screen and keep it horizontal. The carrier 5 is also provided with two third openings 55, and the receiving groove 53 is located between the two third openings 55. The third openings 55 are connected to the positioning space, so that the display screen can be easily placed in the positioning space and also easily removed from the positioning space. The carrier 5 is also provided with a clearance groove 56, which is used to accommodate the connecting cable of the display screen, thereby preventing the connecting cable of the display screen from being damaged during the testing process.

[0028] Reference Figures 4 to 6As shown, the flatness detection device also includes a mounting plate 4 and a rotary drive 6. The bottom center of the mounting plate 4 is connected to the output end of the rotary drive 6, and the plane of the mounting plate 4 is parallel to the plane of the top side of the base 1. The rotary drive 6 can be regarded as a cam divider, and the rotary drive 6 can drive the mounting plate 4 to rotate. Multiple carriers 5 are connected to the mounting plate 4, and the carriers 5 are arranged in a centrally symmetrical manner. In this embodiment, the mounting plate 4 is connected to two carriers 5, so that when the display screen carried by one carrier 5 is being detected, the other carrier 5 can be loaded and unloaded, thereby improving the detection efficiency of the display screen. The mounting plate 4 is provided with a first opening 44, which corresponds to the positioning space of the carrier 5, and a third opening 55 corresponds to the first opening 44, that is, the first opening 44 can cover the third opening 55 and the positioning space in the horizontal direction. The opposite edges of the first opening 44 are also provided with opposite second openings 43, and the maximum distance between the two second openings 43 is greater than the length of the carrier 5, that is, the position of the second opening 43 corresponds to the edge position of the carrier 5, thereby facilitating the connection and disassembly of the carrier 5 and the mounting plate 4. The mounting plate 4 is also connected to two positioning posts 45. The support member 5 has positioning holes 57 corresponding to the positions of the positioning posts 45. The support member 5 is positioned by the engagement of the positioning posts 45 with the positioning holes 57, which also fixes the horizontal position of the support member 5. The support member 5 and the mounting plate 4 can be connected by bolt threads, which makes the connection between the support member 5 and the mounting plate 4 more stable. The mounting plate 4 is also provided with a through hole 41. A sensor 42 is connected to the base 1. The sensing end of the sensor 42 moves towards the through hole 41 to detect the number of rotations of the mounting plate 4.

The support platform is gantry-shaped and includes a support seat 11 and a support plate 14. The two support seats 11 are located at opposite ends of the bottom of the support plate 14. The support seats 11 are connected to the base 1. The base 1 and the support platform are made of marble, which makes the base 1 and the support platform more stable. The first drive mechanism is connected to the support plate 14, and the second drive mechanism is connected to the base 1, and the second drive mechanism is located between the support plate 14 and the base 1.

[0030] The first detection component 2 includes a first driving mechanism and a first detection mechanism. The first detection mechanism is connected to the output end of the first driving mechanism, and the detection end of the first detection mechanism faces the positioning space. The first driving mechanism can be considered as a three-axis driving module. Specifically, the first driving mechanism includes a first driving member 21, a second driving member 22, and a third driving member 25 with mutually perpendicular driving paths. The first driving member 21 is connected to the support plate 14, and the driving path of the first driving member 21 is along the length direction of the support plate 14. The second driving member 22 is connected to the output end of the first driving member 21, and the driving paths of both the first driving member 21 and the second driving member 22 are both located in the horizontal direction. The third driving member 25 is connected to the output end of the second driving member 22, and the first detection mechanism is connected to the output end of the third driving member 25. The third driving member 25 can drive the first detection mechanism to move up and down. The first driving mechanism can drive the first detection mechanism to move in different directions, thereby enabling the first detection mechanism to complete the flatness detection of the display screen.

[0031] The output end of the first driving member 21 is connected to the first movable seat 23. The second driving member 22 is connected to the first movable seat 23. The bottom of the first movable seat 23 is connected to the first support frame 24. A first slide rail 12 is provided on the side of the support plate 14 away from the base 1 along the driving path of the first driving member 21, that is, the top side of the support plate 14 is connected to the first slide rail 12. A second slide rail 13 is provided on the side of the support plate 14 near the carrier 5 along the driving path of the first driving member 21, that is, the side wall of the support plate 14 near the carrier 5 is connected to the second slide rail 13. The first movable seat 23 is slidably connected to the first slide rail 12, and the first support frame 24 is slidably connected to the second slide rail 13. By slidably connecting both the first movable seat 23 and the first support frame 24 to the support plate 14, the movement of the second driving member 22 driven by the first driving member 21 is more stable. The output end of the third driving component 25 is connected to the third movable seat 26. The first detection mechanism includes a first visual detection component 27 and a first planar detection component 28 connected to the controller. The first visual detection component 27 can be regarded as a camera, and the first planar detection component 28 can be regarded as a laser coaxial displacement meter. Both the first visual detection component 27 and the first planar detection component 28 are connected to the third movable seat 26. The detection ends of the first visual detection component 27 and the first planar detection component 28 are both facing the moving path of the carrier 5. When the carrier 5 is in the detection position, the first visual detection component 27 and the first planar detection component 28 can cooperate to perform flatness detection on the display screen, thereby improving the accuracy of the detection.

[0032] Reference Figure 3As shown, the second detection component 3 includes a second drive mechanism and a second detection mechanism. The second detection mechanism is connected to the output end of the second drive mechanism, and the detection end of the second detection mechanism faces the detection port 54. The carrier 5 is located between the first detection mechanism and the second detection mechanism. The second drive mechanism can be regarded as a three-axis drive module. Specifically, the second drive mechanism includes a fourth drive component 31, a fifth drive component 32, and a sixth drive component 35 with mutually perpendicular drive paths. The fourth drive component 31 is connected to the base 1 and located below the support plate 14. The fifth drive component 32 is connected to the output end of the fourth drive component 31, and the sixth drive component 35 is connected to the output end of the fifth drive component 32. The second detection mechanism is connected to the output end of the sixth drive component 35. The drive structure and working principle of the second drive mechanism are the same as those of the first drive mechanism and will not be described again.

[0033] The output end of the fourth drive unit 31 is connected to the second movable seat 33, and the fifth drive unit 32 is connected to the second movable seat 33. The bottom of the second movable seat 33, away from the third drive unit 25, is connected to the second support frame 34. The base 1 is provided with a third slide rail 15 along the drive path of the fourth drive unit 31, and the second support frame 34 is connected to the third slide rail 15, so that the fourth drive unit 31 drives the fifth drive unit 32 to move more stably. The output end of the sixth driving component 35 is connected to the fourth movable seat 36. The second detection mechanism includes a second visual detection component 37 and a second planar detection component 38 connected to the controller. The second visual detection component 37 can be regarded as a camera, and the second planar detection component 38 can be regarded as a laser coaxial displacement meter. Both the second visual detection component 37 and the second planar detection component 38 are connected to the fourth movable seat 36. The detection ends of the second visual detection component 37 and the second planar detection component 38 are both facing the moving path of the carrier 5. When the carrier 5 is in the detection position, the detection ends of the second visual detection component 37 and the second planar detection component 38 face the detection port 54 and can cooperate to perform flatness detection on the display screen, thereby improving the accuracy of the detection.

[0034] In use, the display screen is placed in the positioning space on the support member 5 away from the first detection mechanism, so that the edge of the display screen abuts against the card block 51. Then, the rotating drive member 6 drives the display screen to the detection position. Further, the first drive mechanism drives the first detection mechanism to move, and the first detection mechanism performs flatness detection on one side of the display screen. At the same time, the second drive mechanism drives the second detection mechanism to move, and the second detection mechanism performs flatness detection on the other side of the display screen through the detection port 54.

[0035] This utility model discloses a flatness testing device. A locking block 51 positions the display screen at the testing location. The testing port 54 on the carrier 5 allows the first and second testing mechanisms to simultaneously test the flatness of both sides of the display screen, thus improving testing efficiency. A rotating drive 6 rotates the mounting plate 4, allowing the other carrier 5 to load and unload displays while one carrier is testing, further enhancing testing efficiency.
