[0013] The present invention proposes a flat panel display measurement fixing seat rotation mechanism, which has the following beneficial effects:

[0014] 1. A drive mechanism (worm and worm gear drive) controls the staggered lifting and lowering of the left and right alternating structures, enabling parallel inspection and unloading operations at both stations. As one pickup mechanism grips the display and rises to the inspection position, the other simultaneously descends to complete unloading. A single cycle can process two products. This alternating operation eliminates the need to wait for inspection or unloading to complete, reducing equipment idle time and making it particularly suitable for high-volume inspection on assembly lines.

[0015] 2. The conveyor belt automatically transports the monitor to the designated position. The drive structure, alternating structure and picking structure work together to complete clamping, lifting, flipping and other actions, completely replacing manual loading and unloading and steering adjustment, and avoiding screen scratches or collision damage caused by manual contact. The infrared rangefinder is integrated into the first clamping frame and the second clamping frame, and synchronously measures the length and width of the monitor while clamping, eliminating the problems of false detection and missed detection caused by manual measurement due to fatigue or operational differences.

[0016] 3. The picking structure adopts a spring and clamping rod buffer design. The second clamping frame adjusts the spacing through an electric slide rail, which can adaptively clamp the back shell of monitors of different sizes. It is compatible with various product specifications without changing hardware. The flip component (hydraulic cylinder drives the flip gear) can drive the monitor to flip 180 degrees, so that the screen changes from the buckled state to the upward detection state. The rotation component (second motor drives the carrier plate) supports 0-360 degree rotation to meet the diverse screen angle requirements of different testing equipment (such as backlight uniformity, color deviation and other multi-angle tests).

[0017] 4. The clamping rod and spring work together to form an elastic clamping force. When the second clamping frame contacts the display, the clamping rod is compressed and the spring is compressed, automatically adjusting the clamping force to prevent rigid clamping from damaging the screen frame. It is especially suitable for ultra-thin frame display testing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0028] like Figures 1-8 As shown, the present invention provides a technical solution: a flat-panel display measuring fixed seat rotation mechanism, comprising a base 1, a conveyor belt body 2 is provided on the upper wall of the base 1, the conveyor belt body 2 is used to convey the display, a driving structure 3 is provided on the upper wall of the base 1 near the front end middle, and the driving structure 3 is located in the front middle of the conveyor belt body 2, and alternating structures 4 are symmetrically provided on the left and right sides of the driving structure 3, and the alternating structure 4 is located above the conveyor belt body 2, the driving structure 3 is used to control the two alternating structures 4 to perform staggered lifting and lowering to realize one of the picking up detection, and a picking structure 5 is provided on each of the alternating structures 4, and the picking structure 5 is used to clamp the display.

[0029] As a further solution of the present invention, the driving structure 3 includes a bracket 31, the bracket 31 is fixedly arranged on the upper wall of the base 1, and a driving box 32 is fixedly arranged on the bracket 31. A driving shaft 33 is provided at the rear end of the driving box 32, and the driving shaft 33 is movable through the left and right side walls of the driving box 32. The driving shaft 33 is close to the rear end of the driving box 32, and a first motor 34 is provided on the lower wall of the front end of the driving box 32. The first motor 34 is located in front of the driving shaft 33. A worm 35 is provided on the driving end of the first motor 34, and the worm 35 is located on the driving shaft At the lower middle part of 33, a worm gear 36 is fixedly mounted on the middle part of the drive shaft 33, and the worm gear 36 is engaged with the worm 35. Transfer arms 37 are arranged in opposite directions on both ends of the drive shaft 33, and a transfer wheel 38 is movably arranged on the other end of the transfer arm 37, and the transfer wheel 38 can rotate; the drive box 32 is supported by the bracket 31 to have a certain height, and the worm 35 is driven to rotate by the first motor 34, so that the worm 35 and the worm gear 36 are engaged with each other, driving the drive shaft 33 to rotate, and finally realizing the alternating rotation of the transfer arms 37 arranged in opposite directions at both ends of the drive shaft 33.

[0030] More specifically, after the first motor 34 is powered on, its driving end drives the worm 35 to start rotating. Since the worm 35 and the worm wheel 36 are engaged with each other, the rotational motion of the worm 35 is transmitted to the worm wheel 36, thereby driving the drive shaft 33 to rotate; the transfer arms 37 arranged in opposite directions at both ends of the drive shaft 33 swing synchronously with the rotation of the drive shaft 33, and the transfer wheel 38 at the other end of the transfer arm 37 rolls along the wheel track 44 on the first flip arm 42 in the alternating structure 4 during the swinging process.

[0031] As a further solution of the present invention, the alternating structure 4 includes a support arm 41, one end of the support arm 41 is fixedly provided on the upper wall of the base 1 and is located on the right side of the drive box 32, the support arm 41 is located in front of the drive shaft 33, the other end of the support arm 41 is movably connected to the first flip arm 42, the other end of the first flip arm 42 is movably connected to the second flip arm 43, and the second flip arm 43 can be parallel to the first flip arm 42, the first flip arm 42 is fixedly provided with a wheel rail 44 near the middle, and the wheel rail 44 is movably mounted on the adapter wheel 38, the other end of the second flip arm 43 is movably connected to a lifting frame 45, the lifting frame 45 is T-shaped, and a sliding groove is provided in the middle of the rear end of the lifting frame 45, and a lifting rod 46 is movably mounted on the lifting frame 45, and The bottom end of the lifting rod 46 is fixedly set on the base 1, and a flip assembly 47 is provided at the rear end of the lifting frame 45 near the sliding groove. A rotating assembly 48 is fixedly provided on the flip assembly 47, and the rotating assembly 48 corresponds to the conveyor belt body 2; the first flip arm 42 is supported by the support arm 41, and the wheel rail 44 is driven by the adapter wheel 38 to flip on the support arm 41 with the help of the first flip arm 42. The lifting frame 45 is limited by the lifting rod 46, which indirectly leads to the limitation of the second flip arm 43, and then during the flipping of the first flip arm 42, the angle between the first flip arm 42 and the second flip arm 43 will be adjusted. As the flip angle between the first flip arm 42 and the second flip arm 43 increases, the lifting frame 45 is forced to move upward on the lifting rod 46.

[0032] More specifically, during the rolling process of the transfer wheel 38, the transfer wheel 38 exerts a force on the wheel rail 44, thereby driving the first flip arm 42 to flip on the support arm 41; because the lifting frame 45 is connected to the base 1 through the lifting rod 46, the lifting rod 46 acts as a limiter for the lifting frame 45, so when the first flip arm 42 flips, it will drive the second flip arm 43 to move together, and at the same time, the angle between the first flip arm 42 and the second flip arm 43 will change; when the angle between the first flip arm 42 and the second flip arm 43 increases, the lifting frame 45 will move upward on the lifting rod 46; conversely, when the angle decreases, the lifting frame 45 moves downward.

[0033] As a further solution of the present invention, the flipping assembly 47 includes a flipping shaft 471, which movably passes through the rear end of the lifting frame 45. A flipping gear 472 is fixedly mounted on one end of the flipping shaft 471. The flipping gear 472 rotates by engaging with one end of the tooth arm 474, and the other end of the tooth arm 474 movably passes through the sliding groove. The tooth arm 474 moves back and forth through the hydraulic cylinder 473, and the hydraulic cylinder 473 is fixedly arranged at the rear end of the lifting frame 45; the hydraulic cylinder 473 drives the tooth arm 474 to move back and forth, so that the tooth arm 474 drives the flipping gear 472 to rotate with the help of the flipping shaft 471.

[0034] More specifically, the piston rod of the hydraulic cylinder 473 extends or contracts, pushing the tooth arm 474 to move along the sliding groove at the rear end of the lifting frame 45. Since the teeth at one end of the tooth arm 474 are engaged with the flip gear 472, the flip gear 472 will be driven to rotate around the flip axis 471.

[0035] As a further solution of the present invention, the rotating assembly 48 includes a base plate 481, a second motor 482 and a supporting plate 483; the middle part of one end of the base plate 481 is fixedly arranged on the other end of the flip shaft 471, the second motor 482 is fixedly arranged on the middle part of the upper wall of the base plate 481, and the driving end of the second motor 482 is movable through the base plate 481, the supporting plate 483 is fixedly arranged on the driving end of the second motor 482, and the supporting plate 483 is located below the base plate 481, and the supporting plate 483 can be rotated by the second motor 482; the second motor 482 drives the supporting plate 483 to rotate to adjust the direction of the picking structure 5.

[0036] More specifically, when the rotating assembly 48 flips 180 degrees, the display is in the detection position with the screen facing upward, that is, the picking structure 5 is located above the supporting plate 483, and during the detection, the picking structure 5 is driven by the second motor 482 to rotate and adjust the orientation of the display screen.

[0037] As a further solution of the present invention, the picking structure 5 includes an electric slide rail 51, a first clamping frame 52, a plurality of clamping rods 53, a plurality of springs 54 and a second clamping frame 55; the electric slide rail 51 is fixedly arranged on the lower wall of one end of the supporting plate 483, the first clamping frame 52 is T-shaped, and the first clamping frame 52 is fixedly arranged on the lower wall of the rotating plate. One ends of a plurality of clamping rods 53 are equidistantly movable through the first clamping frame 52, and a plurality of springs 54 are movably mounted on the clamping rod 53. The second clamping frame 55 is fixedly arranged on the electric slide rail 51, and the second clamping frame 55 corresponds to the clamping rod 53. The second clamping frame 55 moves back and forth through the electric slide rail 51; the second clamping frame 52 is driven by the electric slide rail 51 to move relative to the first clamping frame 55, and the second clamping frame 52 cooperates with the clamping rod 53 to clamp and apply force to fix the display, and the clamping rod 53 can be compressed by the force to buffer the spring 54.

[0038] More specifically, the electric slide 51 drives the second clamping frame 55 to the farthest position, the spring 54 is in a naturally extended state, and the clamping rod 53 extends out of the first clamping frame 52 to the maximum length; at this time, when the overall height of the picking structure 5 is relatively low, it is convenient to approach the display on the conveyor belt body 2, and the lifting frame 45 descends, so that the picking structure 5 as a whole is close to the display, and the electric slide 51 starts, driving the second clamping frame 55 to move toward the first clamping frame 52. The second clamping frame 55 first contacts one side edge of the display. As it continues to move, the display is pushed toward the clamping rod 53. After the clamping rod 53 contacts the other side edge of the display, it encounters resistance and begins to compress the spring 54 and slide axially. Infrared rangefinders 6 are symmetrically arranged on the first clamping frame 52 and the second clamping frame 55.

[0039] In this embodiment, in order to relieve the relative clamping force between the first clamping frame 52 and the second clamping frame 55 , the other end of the clamping rod 53 is forced to move toward the first clamping frame 52 to compress the spring 54 .

[0040] In this embodiment, in order to achieve stable clamping of the display, the pick-up structure 5 is opposite to the housing on the back of the display, and the screen of the display is buckled onto the conveyor belt body 2.

[0041] In this embodiment, in order to realize double-station detection, the alternating structure 4 drives one display to rise and fall respectively for picking up detection and unloading blanks.

[0042] In this embodiment, in order to maintain the stable lifting and lowering of the alternating structure 4, the worm 35 drives the worm wheel 36.

[0043] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0044] S1. First: After the equipment is powered on, the display needs to be loaded onto the conveyor belt body 2 on the upper wall of the base 1. The display is buckled onto the conveyor belt body 2 through a belt-type conveying method, and can be placed stably and moved with the drive of the conveyor belt body 2;

[0045] S2. When the display to be tested is smoothly conveyed by the conveyor belt body 2 to the working area, that is, positioned directly below the pickup structure 5, the drive structure 3 is started, and the first motor 34 located in the drive box 32 is energized, driving the worm 35 to rotate. The engagement between the worm 35 and the worm gear 36 drives the drive shaft 33 to rotate, thereby driving the oppositely arranged transfer arms 37 to rotate alternately with the support of the bracket 31;

[0046] S3. Secondly, in the coordinated movement stage of the alternating structure 4, the drive shaft 33 is linked to the transfer arm 37. When the drive shaft 33 rotates, the transfer arms 37 fixed at both ends swing synchronously, and the movable transfer wheel 38 moves and rotates in the wheel track 44 on the first flip arm 42, pushing the transfer wheel 38 to roll along the wheel track 44, driving the first flip arm 42 to flip on the support arm 41. Because the lifting frame 45 is limited by the lifting rod 46, when the first flip arm 42 flips, the second flip arm 43 is also driven to flip. However, when the lifting frame 45 is limited, the first flip arm 42 will expand or contract the angle relative to the second flip arm 43, thereby driving the lifting frame 45 to be forced to move up and down on the lifting rod 46;

[0047] S4. When the corresponding lifting frame 45 drives the picking structure 5 to descend, the picking structure 5 reaches the monitor clamping position and places the first clamping frame 52 and the second clamping frame 55 on the front and back sides of the monitor. At this time, the electric slide rail 51 is driven to drive the second clamping frame 55 to move toward the first clamping frame 52 for clamping. As the clamping force is applied, the clamping rod 53 contacts the monitor and the clamping rod 53 can extend and retract on the first clamping frame 52 and compress the spring 54 to buffer the clamping force, thereby preventing excessive clamping force.

[0048] S5. After clamping, the hydraulic cylinder 473 in the flip assembly 47 is driven. The hydraulic cylinder 473 contracts, driving the gear arm 474 to translate along the slide. The gear arm 474 drives the flip gear 472 to rotate along the flip shaft 471 during movement, thereby driving the bottom plate 481 to flip 180 degrees, causing the display screen located below the bottom plate 481 to face upward for detection.

[0049] S6. The rotating assembly 48 can also flip the screen to a certain angle for testing after the screen is facing upward, so that the screen can be tilted for receiving light and observing different tests. During the test, the second motor 482 can also be used to drive the supporting plate 483 to rotate to adjust the direction of the display.

[0050] S7, the two sets of alternating structures 4 are used to perform alternating lifting and lowering to realize the picking and lowering, and the alternating use of the two workstations. After the detection is completed, the electric slide 51 moves backward to release the second clamping frame 55, the spring 54 resets the clamping rod 53, and the display is placed back on the conveyor belt body 2, ready for the next clamping;

[0051] S8. When the first clamping frame 52 and the second clamping frame 55 clamp the display, the relative width of the clamping edge can also be measured with the help of infrared distance measurement. If only the distance between the two sides is measured during clamping, the supporting plate 483 can be rotated, and then the display can be lowered and the other two sides can be re-clamped to achieve the overall length and width measurement.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
