[0003] The existing display screen transfer devices mainly rely on manual operation, with low efficiency and easy to make mistakes. The functions of traditional devices are relatively single and cannot meet the diverse production needs. For example, during the display screen detection process, a two-dimensional code information is attached to the back side of the display screen, which needs to be read by the device, but the two-dimensional code needs to be kept facing up all the time. Therefore, it is necessary to turn over the inverted two-dimensional code of the display screen. For this reason, a display screen transfer device is needed to solve the existing deficiencies.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a display transfer device, including a base 1, a conveyor belt 2 and a workpiece 3. A set of symmetric guide frames 4 are fixedly connected to the top end of the base 1. The conveyor belt 2 penetrates through the opposite sides of the guide frames 4. The workpiece 3 is placed on the surface of the conveyor belt 2, and the width of the workpiece 3 is slightly larger than the width of the conveyor belt 2. Flipping mechanisms 5 are arranged on the inner sides of the guide frames 4, and the flipping mechanisms 5 are movably connected to the sides of the workpiece 3. A lifting mechanism 6 is arranged at the inner bottom end of the base 1, and the lifting mechanism 6 is fixedly connected to the bottom end of the flipping mechanism 5. A top plate 7 is fixedly connected to the top end of the guide frame 4, and a positive and negative detector 8 is fixedly connected to one side of the top plate 7.

[0023] As Figure 1 and Figure 4As shown, the flipping mechanism 5 includes a moving block 501, a rotating column 502, a cross block 503, a sleeve 504 and a clamping strip 505. The clamping strip 505 is in an X shape, and the clamping strips 505 are all fixedly connected to the outside of the sleeve 504. The rotating column 502 penetrates through the moving block 501, and the rotating column 502 is movably connected to the moving block 501. The cross block 503 is fixedly connected to one end of the rotating column 502. The sleeve 504 is sleeved on the outside of the cross block 503, and the sleeve 504 is movably connected to the cross block 503. The moving block 501 is movably connected to the inside of the guiding frame 4. The side of the workpiece 3 is clamped to the opposite side of the clamping strip 505. A first servo motor 9 is fixedly connected to the outside of the moving block 501, and the output end of the first servo motor 9 is fixedly connected to one end of the rotating column 502. A moving plate 10 is rotatably connected to the outside of the sleeve 504. A hydraulic rod 11 is fixedly connected to the top of the moving block 501, and the telescopic end of the hydraulic rod 11 is fixedly connected to one side of the moving plate 10.

[0024] Start the hydraulic rod 11 to push the sleeve 504 to move along the cross bar, so as to control the clamping strip 505 to approach the side of the workpiece 3. Since the clamping strips 505 are distributed in an X shape, the side of the workpiece 3 is clamped to the opposite side of the clamping strip 505. After the workpiece 3 is lifted, start the first servo motor 9 to control the rotation of the rotating column 502, so as to drive the cross block 503 and the sleeve 504 to rotate synchronously, thereby turning over the workpiece 3 and keeping the information two-dimensional code of the workpiece 3 facing up all the time, which is beneficial to the subsequent rapid detection of the workpiece 3.

[0025] As Figure 1 , Figure 3 and Figure 5 shown, the lifting mechanism 6 includes a control rod 601, a gear 602, a telescopic rod 603 and a support base 604. The control rod 601 and the gear 602 are both arranged symmetrically left and right, and the support base 604 is arranged symmetrically front and back. The control rod 601 penetrates through the gear 602 respectively, and the control rod 601 is fixedly connected to the gear 602. A group of symmetric telescopic rods 603 are fixedly connected to the outside of the control rod 601, and the gear 602 is located on the opposite side of the telescopic rod 603. The two ends of the control rod 601 are movably connected to the inside of the support base 604 respectively, and the gears 602 are meshed with each other. The bottom ends of the support bases 604 are all fixedly connected to the bottom end of the base 1. A second servo motor 12 is fixedly connected to the top end of the support base 604, and the output end of the second servo motor 12 is fixedly connected to one end of the control rod 601. A group of symmetric connecting rods 13 are fixedly connected to the bottom end of the moving block 501. The connecting rods 13 penetrate through the bottom end of the guiding frame 4, and the connecting rods 13 are movably connected to the guiding frame 4. A connecting plate 14 is fixedly connected to the bottom end of the connecting rod 13, and the ends of the telescopic rods 603 far from the control rod 601 are all rotatably connected to the side of the connecting plate 14 through a rotating shaft.

[0026] Start the second servo motor 12 to drive the single control rod 601 to rotate. Under the action of the gear 602, the other control rod 601 rotates in the opposite direction, so that the telescopic rod 603 rotates upward around the axis of the control rod 601, thereby jacking up the connecting plate 14. The length of the telescopic rod 603 is automatically adjusted according to the height of the connecting plate 14. Under the action of the connecting rod 13, the moving block 501 moves upward along the guide frame 4, thereby driving the workpiece 3 to be lifted, which helps the workpiece 3 to be flipped and avoids the friction between the workpiece 3 and the conveyor belt 2 during the flipping process.

[0027] Working principle: During use, the workpiece 3 is transported by the conveyor belt, and the positive and negative detector 8 is used to measure whether the two-dimensional code identification of the workpiece 3 is on the top surface or the bottom surface. When the two-dimensional code identification of the workpiece 3 is inverted, after the workpiece 3 moves to the opposite side of the guide frame 4, the hydraulic rod 11 is started to push the sleeve 504 to move along the cross bar, thereby controlling the clamping bar 505 to approach the side of the workpiece 3. Since the clamping bars 505 are distributed in an X shape, the side of the workpiece 3 is clamped to the opposite side of the clamping bar 505. Subsequently, the second servo motor 12 is started to drive the single control rod 601 to rotate. Under the action of the gear 602, the other control rod 601 rotates in the opposite direction, so that the telescopic rod 603 rotates upward around the axis of the control rod 601, thereby jacking up the connecting plate 14. The length of the telescopic rod 603 is automatically adjusted according to the height of the connecting plate 14. Under the action of the connecting rod 13, the moving block 501 moves upward along the guide frame 4, thereby driving the workpiece 3 to be lifted. The first servo motor 9 is started to control the rotation of the rotating column 502, thereby driving the cross block 503 and the sleeve 504 to rotate synchronously, so as to turn the workpiece 3 over. Subsequently, the reverse operation is performed. After the workpiece 3 is put down, the clamping bar 505 is withdrawn.
