The lifting frame is T-shaped, the front end of the lifting frame is movably connected to the other end of the second flipping arm, a sliding groove is formed in the middle of the rear end of the lifting frame, one end of the lifting rod is fixedly arranged on the upper wall of the base, and the other end of the lifting rod movably penetrates through the middle of the lifting frame. The flipping assembly is fixedly arranged on the rear end of the lifting frame, the rotating assembly is fixedly arranged on the flipping assembly, and the rotating assembly is located on the rear side of the right end of the lifting frame. The rotating assembly corresponds to the conveyor belt body. The flipping assembly is used to control the rotating assembly to flip 180 degrees, and the rotating assembly is used to drive the display to rotate and adjust the direction.

[0007] Preferably, the picking structure includes an electric slide rail, a first clamping frame, a plurality of clamping rods, a plurality of springs, and a second clamping frame; the electric slide rail is fixedly arranged on the rotating assembly, the first clamping frame is T-shaped and is fixedly arranged on the rotating assembly, one ends of the plurality of clamping rods respectively penetrate through the first clamping frame at equal intervals, the plurality of springs are respectively movably sleeved on the clamping rods, the second clamping frame is fixedly arranged on the electric slide rail, and the second clamping frame corresponds to the clamping rods.

[0014] 2. The conveyor belt body automatically conveys the display to the designated position. The driving structure, alternating structure and picking structure are linked to complete actions such as clamping, lifting and flipping, completely replacing manual loading and unloading and steering adjustment, avoiding screen scratches or collision damage caused by manual contact. The infrared rangefinder is integrated into the first clamp and the second clamp to synchronously measure the length and width dimensions when clamping the display, eliminating false detection and missed detection problems caused by fatigue or operation differences in manual measurement.

[0015] 3. The picking structure adopts a spring and clamp rod buffer design. The second clamp adjusts the distance through an electric slide rail, and can adaptively clamp the back shell of displays of different sizes, and can be compatible with a variety of product specifications without replacing hardware; the flipping component (hydraulic cylinder drives the flipping gear) can drive the display to flip 180 degrees, so that the screen changes from the buckled state to the upward detection state; the rotating component (the second motor drives the bearing plate) supports 0-360 degree rotation, meeting the diverse requirements of different detection devices for the screen angle (such as multi-angle tests of backlight uniformity, color deviation, etc.).

[0016] 4. The clamp rod and the spring cooperate to form an elastic clamping force. When the second clamp contacts the display, the clamp rod compresses the spring under pressure, automatically adjusting the clamping force to prevent rigid clamping from damaging the screen frame, and is especially suitable for the detection of ultra-thin bezel displays.

DETAILED DESCRIPTION

[0019] The specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1-8 As shown, the present invention provides a technical solution: a flat display measuring fixed seat rotation mechanism, comprising a base 1, a conveyor belt body 2 is arranged on the upper wall of the base 1, the conveyor belt body 2 is used to convey the display, a driving structure 3 is arranged 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 arranged 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 them picking up detection, and the alternating structures 4 are all provided with picking structures 5, and the display is clamped by the picking structure 5.

[0021] 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, a driving box 32 is fixedly arranged on the bracket 31, a driving shaft 33 is movably penetrated through the rear end of the driving box 32, and the driving shaft 33 movably penetrates 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. A first motor 34 is arranged on the inner lower wall at the front end of the driving box 32, and the first motor 34 is located on the front side of the driving shaft 33. A worm 35 is arranged on the driving end of the first motor 34, and the worm 35 is located below the middle of the driving shaft 33. A worm gear 36 is fixedly sleeved on the middle of the driving shaft 33, and the worm gear 36 is engaged with the worm 35. Transfer arms 37 are arranged in opposite directions at both ends of the driving shaft 33, and transfer wheels 38 are movably arranged at the other ends of the transfer arms 37, and the transfer wheels 38 can rotate; the bracket 31 supports the driving box 32 at a certain height. The first motor 34 drives the worm 35 to rotate, realizing the meshing transmission between the worm 35 and the worm gear 36, driving the driving shaft 33 to rotate, and finally realizing the alternating rotation of the transfer arms 37 arranged in opposite directions at both ends of the driving shaft 33.

[0022] More specifically, after the first motor 34 is powered on, its driving end drives the worm 35 to start rotating. Since the worm 35 is engaged with the worm gear 36, the rotational movement of the worm 35 is transmitted to the worm gear 36, thereby driving the driving shaft 33 to rotate; the transfer arms 37 arranged in opposite directions at both ends of the driving shaft 33 swing synchronously with the rotation of the driving shaft 33, and the transfer wheels 38 at the other ends of the transfer arms 37 roll along the wheel rails 44 on the first turning arm 42 in the alternating structure 4 during the swinging process.

[0023] 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 arranged 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 with a first flipping arm 42. The other end of the first flipping arm 42 is movably connected with a second flipping arm 43, and the second flipping arm 43 can be parallel to the first flipping arm 42. A wheel rail 44 is fixedly arranged near the middle of the first flipping arm 42, and the wheel rail 44 is movably sleeved on the transfer wheel 38. The other end of the second flipping arm 43 is movably connected with a lifting frame 45. The lifting frame 45 is T-shaped, and a sliding groove is opened in the middle of the rear end of the lifting frame 45. A lifting rod 46 is movably sleeved on the lifting frame 45, and the bottom end of the lifting rod 46 is fixedly arranged on the base 1. A flipping assembly 47 is arranged at the position of the rear end of the lifting frame 45 near the sliding groove. A rotating assembly 48 is fixedly arranged on the flipping assembly 47, and the rotating assembly 48 corresponds to the conveyor belt main body 2; the first flipping arm 42 is supported by the support arm 41. The wheel rail 44 is driven by the transfer wheel 38 and flips on the support arm 41 by means of the first flipping arm 42. The lifting frame 45 is limited by the lifting rod 46, indirectly causing the second flipping arm 43 to be limited. Furthermore, during the flipping of the first flipping arm 42, the included angle between the first flipping arm 42 and the second flipping arm 43 will be adjusted to change. As the included angle between the first flipping arm 42 and the second flipping arm 43 becomes larger during flipping, the lifting frame 45 is forced to move upward on the lifting rod 46.

[0024] More specifically, during the rolling of the transfer wheel 38, the transfer wheel 38 exerts a force on the wheel rail 44, thereby driving the first flipping arm 42 to perform a flipping movement on the support arm 41; since the lifting frame 45 is connected to the base 1 through the lifting rod 46, and the lifting rod 46 plays a limiting role on the lifting frame 45, when the first flipping arm 42 flips, it will drive the second flipping arm 43 to move together, and at the same time, the included angle between the first flipping arm 42 and the second flipping arm 43 will change; when the included angle between the first flipping arm 42 and the second flipping arm 43 increases, the lifting frame 45 will move upward on the lifting rod 46; conversely, when the included angle decreases, the lifting frame 45 will move downward.

[0025] As a further solution of the present invention, the flipping assembly 47 includes a flipping shaft 471. The flipping shaft 471 movably penetrates the rear end of the lifting frame 45. A flipping gear 472 is fixedly sleeved on one end of the flipping shaft 471. The flipping gear 472 rotates by engaging with one end of a tooth arm 474, and the other end of the tooth arm 474 movably penetrates the sliding groove. The tooth arm 474 moves back and forth through a hydraulic cylinder 473, and the hydraulic cylinder 473 is fixedly arranged at the rear end of the lifting frame 45; by driving the tooth arm 474 to move back and forth through the hydraulic cylinder 473, the tooth arm 474 is enabled to drive the flipping gear 472 to rotate by means of the flipping shaft 471.

[0026] 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 mesh with the reversing gear 472, the reversing gear 472 will be driven to rotate around the reversing shaft 471.

[0027] As a further solution of the present invention, the rotating assembly 48 includes a bottom plate 481, a second motor 482 and a bearing plate 483; the middle of one end of the bottom plate 481 is fixedly arranged on the other end of the reversing shaft 471, the second motor 482 is fixedly arranged in the middle of the upper wall of the bottom plate 481, and the driving end of the second motor 482 movably penetrates the bottom plate 481, the bearing plate 483 is fixedly arranged on the driving end of the second motor 482, and the bearing plate 483 is located below the bottom plate 481, and the bearing plate 483 can rotate through the second motor 482; the second motor 482 drives the bearing plate 483 to rotate to adjust the orientation of the picking structure 5.

[0028] More specifically, when the rotating assembly 48 is flipped 180 degrees, the display is in the detection position with the screen facing up, that is, the picking structure 5 is located above the bearing plate 483, and the second motor 482 drives the picking structure 5 to rotate to adjust the orientation of the display screen during detection.

[0029] As a further solution of the present invention, the picking structure 5 includes an electric slide rail 51, a first clamp 52, a plurality of clamp rods 53, a plurality of springs 54 and a second clamp 55; the electric slide rail 51 is fixedly arranged on the lower wall of one end of the bearing plate 483, the first clamp 52 is T-shaped, the first clamp 52 is fixedly arranged on the lower wall of the rotating plate, one ends of the plurality of clamp rods 53 respectively penetrate through the first clamp 52 at equal intervals, the plurality of springs 54 are respectively movably sleeved on the clamp rods 53, the second clamp 55 is fixedly arranged on the electric slide rail 51, and the second clamp 55 corresponds to the clamp rods 53, and the second clamp 55 moves back and forth through the electric slide rail 51; the electric slide rail 51 drives the second clamp 52 to move relative to the first clamp 55, and the second clamp 52 and the clamp rods 53 cooperate to clamp and apply force to fix the display, and the clamp rods 53 can be compressed by force to buffer the spring 54.

[0030] More specifically, the electric slide rail 51 drives the second clamp 55 to be in the farthest position, the spring 54 is in the natural elongation state, and the length of the clamp rod 53 extending out of the first clamp 52 is the largest; 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 main body 2. The lifting frame 45 descends, so that the picking structure 5 is close to the display as a whole. The electric slide rail 51 is started to drive the second clamp 55 to move towards the first clamp 52. The second clamp 55 first contacts one side edge of the display. As it continues to move, the display is pushed towards the clamp rod 53. After the clamp rod 53 contacts the other side edge of the display and is resisted, it starts to compress the spring 54 and slide axially. Infrared rangefinders 6 are symmetrically arranged on the first clamp 52 and the second clamp 55.

[0031] 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 towards the first clamping frame 52 to compress the spring 54.

[0032] In this embodiment, in order to stably clamp the display, the picking structure 5 faces the outer shell on the back of the display, and the screen of the display is buckled on the conveyor belt main body 2.

[0033] In this embodiment, in order to realize double-station detection, the alternating structure 4 drives one display to lift alternately for picking up and detecting and unloading.

[0034] In this embodiment, in order to keep the alternating structure 4 lifting stably, it is driven by the worm 35 driving the worm wheel 36.

[0035] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0036] S1. First: After the device is powered on, the display needs to be loaded onto the conveyor belt main body 2 on the upper wall of the base 1. Through the belt-type conveying method, the display is buckled on the conveyor belt main body 2, and then it can be placed stably and moved along with the drive of the conveyor belt main body 2; S2. The display to be tested is stably conveyed by the conveyor belt main body 2 to the working area, that is, when it is positioned directly below the picking structure 5, the driving structure 3 is started. The first motor 34 in the driving box 32 is powered on, driving the worm 35 to rotate. Through the meshing of the worm 35 and the worm wheel 36, the driving shaft 33 is driven to rotate, and then the alternately arranged connecting arms 37 are driven to rotate alternately with the support of the bracket 31; S3. Secondly, in the stage of the coordinated movement of the alternating structure 4, the driving shaft 33 drives the connecting arm 37. When the driving shaft 33 rotates, the connecting arms 37 fixed at both ends swing synchronously. The movably arranged transfer wheel 38 moves and rotates in the wheel track 44 on the first turning arm 42, pushing the transfer wheel 38 to roll along the wheel track 44, driving the first turning arm 42 to turn on the support arm 41. Since the lifting frame 45 is limited by the lifting rod 46, when the first turning arm 42 turns, the second turning arm 43 will also be driven to turn. However, in the state where the lifting frame 45 is limited, the included angle between the first turning arm 42 and the second turning arm 43 will increase or decrease, and then the lifting frame 45 is forced to move up and down on the lifting rod 46; S4. After the corresponding lifting frame 45 drives the picking structure 5 to descend, the picking structure 5 reaches the display clamping position, and the first clamping frame 52 and the second clamping frame 55 are located on the front and back sides of the display. At this time, the electric slide rail 51 can be driven to drive the second clamping frame 55 to move towards the first clamping frame 52 for clamping. As the clamping clamping rod 53 is stressed, it will contact the display, and the clamping rod 53 can stretch and compress the spring 54 on the first clamping frame 52 for buffering to prevent excessive clamping force; S5. After clamping, the hydraulic cylinder 473 in the flipping assembly 47 is driven. The contraction of the hydraulic cylinder 473 drives the tooth arm 474 to translate along the chute, and the moving tooth arm 474 drives the flipping gear 472 to rotate around the flipping shaft 471, thereby driving the bottom plate 481 to flip 180 degrees, so that the display screen located below the bottom plate 481 faces upward for detection; S6. After the screen faces upward, the rotating assembly 48 can also flip a certain angle for detection, so that the screen can be in an inclined state for light reception and observation of different detections. During the detection, the second motor 482 can be used to drive the bearing plate 483 to rotate to adjust the orientation of the display; S7. Through the lifting alternation of the two sets of alternation structures 4, picking and lowering are realized, and the alternation of two workstations is realized. After the detection is completed, the electric slide rail 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 main body 2 to prepare for the next clamping; 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 by means of infrared distance measurement. If only the distance between the two sides is measured during clamping, the bearing plate 483 can be rotated, and after the display is lowered and then placed, the other two sides can be re-clamped to realize the overall length and width measurement.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
