Description

Technical Field

[0001] The utility model relates to the technical field of display screen production, in particular to a panel turning machine for producing and processing LED display screens. Background Art

[0002] During the production and processing of LED displays, it is necessary to flip the display screen for assembly, inspection, and transportation. In the prior art, patent document CN216637985U discloses a flipping machine for the production and processing of LED displays, comprising a base, a display conveyor, a motor, and two mounting side panels fixedly connected to the top of the base, and a rotating cylinder movably connected to the opposite sides of the two mounting side panels, and a plurality of clamping grooves are formed on the outer wall of the rotating cylinder. This flipping machine for the production and processing of LED displays uses rolling rollers to allow the display screen to be flexibly pushed into the clamping groove by the display conveyor. When the pressure plate is driven downward by an electronic telescopic rod, the display screen is further limited, making the display screen more stable when flipping clockwise. At the same time, the provision of a flexible pad and a shock-absorbing layer further prevents bumps on the display screen surface, providing higher safety. The provision of multiple clamping grooves increases the number of displays that can be flipped per unit time, effectively improving production efficiency. At the same time, the clamping grooves running through both sides of the rotating cylinder do not limit the width of the display screen.

[0003] In actual use, rotating rollers are used to flip the products. If the products are not discharged from the rotating rollers in time, they are likely to get stuck or even damaged. Relying only on the conveyor belts on both sides, the pushing force on the display is very limited, and the conveyed display is prone to slipping, which is very inconvenient to use. Based on this, the existing flipping device has the problem of unreliability in flipping and conveying the display, and needs further improvement. Utility Model Content

[0026] Two tensioning seats 9 are fixedly installed inside the flip frame 1, and a tensioning shaft 10 is rotatably installed between the two tensioning seats 9. The tensioning shaft 10 presses against the surface of the transmission belt 5, wherein the tensioning seat 9 includes a seat body 11, and a sliding block 12 and an adjusting plate 13 are slidably installed inside the seat body 11. A support spring 14 is arranged between the adjusting plate 13 and the sliding block 12, and the end of the tensioning shaft 10 is rotatably connected to the sliding block 12.

[0027] An adjusting bolt 15 is threadedly installed at the bottom of the seat body 11, and the end of the adjusting bolt 15 is in tight contact with the adjusting plate 13. A pressing column 16 is fixedly installed on the upper side of the sliding block 12, and the top of the pressing column 16 is slidably connected to the seat body 11 and extends to the upper side of the seat body 11.

[0028] A guiding and positioning assembly is provided on the upper side of the flip frame 1. Specifically, the guiding and positioning assembly includes a mounting plate 17 fixedly mounted on both sides of the flip frame 1. Adjustable limiting side plates 18 are mounted on the lower sides of the mounting plates 17 on both sides. Rubber pads are fixedly mounted on the inner sides of the two limiting side plates 18.

[0030] Working principle: During use, Figure 3 As shown, the loading conveyor 22 transports the LED display screen to one end of the flip frame 1, and the first servo motor 7 is started to drive the transmission belt 5 to operate. When the LED display screen contacts the transmission belt 5, the transmission belt 5 operates to drive the LED display screen to move into the flip splint 6. At this time, the second servo motor 8 is started to drive the flip splint 6 to flip 180°, so that the upper surface of the LED display screen becomes facing downward and falls onto the transmission belt 5. As the transmission belt 5 runs, the LED display screen is pushed onto the unloading conveyor 23. Finally, the first servo motor 7 rotates in the opposite direction to drive the flip splint 6 to flip 180° in the opposite direction to flip and transport the next LED display screen.

[0031] By setting the tensioning seat 9 and the tensioning shaft 10, the tensioning shaft 10 is used to tighten the transmission belt 5, and the elastic force of the support spring 14 can be adjusted by rotating the adjusting bolt 15 to change the tensioning force of the tensioning shaft 10 on the transmission belt 5. When the flipping splint 6 turns over the display screen, the display screen contacts the transmission belt 55, and the transmission belt 5 can absorb the impact of the display screen well to prevent damage from bumps, making it safer to use.

[0032] The flipping machine for producing and processing LED display screens is configured by arranging multiple transmission belts 5 between a first transmission roller 3 and a second transmission roller 4. Adjacent transmission belts 5 have gaps reserved therebetween to allow a flipping plate 6 to swing back and forth, and the flipping plate 6 flips the display screen. This design increases the contact area between the transmission belt 5 and the display screen, improves the friction, and enables the display screen to be smoothly removed from the flipping plate 6, thereby improving the reliability of flipping and conveying the display screen.
