Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0025] Please refer to Figures 1-8 . The flipping tooling for LED display production includes: a turning table 1, at the bottom of which two support legs are fixedly installed, and a supporting sliding column 2 is slidably installed on the turning table 1. The top of the supporting sliding column 2 is fixedly installed with a supporting panel 3 for placing the LED display. At the bottom of the turning table 1, two rodless cylinders 5 are fixedly installed. On the sliders of the two rodless cylinders 5, the same connecting strip is fixedly installed, and the top of the connecting strip is fixedly connected with the supporting sliding column 2. The lifting of the slider of the rodless cylinder 5 is used to drive the supporting panel 3 to lift. Above the turning table 1, there are a first transverse moving plate 8 and a second transverse moving plate 9. A driving shaft 10 is rotatably installed on the first transverse moving plate 8, and a second driving motor is fixedly installed on the first transverse moving plate 8, and the output shaft thereof is fixedly connected with one end of the driving shaft 10. A driven shaft 11 is rotatably installed on the second transverse moving plate 9. At the mutually approaching ends of the driving shaft 10 and the driven shaft 11, C-shaped frames 12 are fixedly installed. At the tops of the two C-shaped frames 12, pressing screws 13 are threadedly installed. At the bottoms of the two pressing screws 13, pressing pieces 14 are rotatably installed. And on the tops of the two C-shaped frames 12, limiting rods are slidably installed. The bottoms of the two limiting rods are respectively fixedly connected with the two pressing pieces 14, so as to ensure that the pressing pieces 14 can only perform linear lifting. And the inner walls of the bottoms of the two C-shaped frames 12 are flush with the top end faces of the supporting panel 3. On one side of the turning table 1, two connectors are fixedly installed, and at the ends of the two connectors, the same backrest plate 17 is fixedly installed. A longitudinal push rod 21 is slidably installed thereon. At the end of the longitudinal push rod 21 close to the supporting panel 3, a pushing piece 22 is fixedly installed. The bottom of the pushing piece 22 is slightly higher than the top end face of the supporting panel 3. A pushing mechanism is provided on the backrest plate 17 for pushing the pushing piece 22.

[0026] In the above method, in order to drive the first transverse plate 8 and the second transverse plate 9 to move towards each other, an activity through groove 4 is formed in the support sliding column 2. Two side frame plates 6 are fixedly installed at the top of the flipping table 1. The same bidirectional lead screw 7 is rotatably installed on the two side frame plates 6. A first driving motor is fixedly installed on one of the side frame plates 6, and its output shaft is fixedly connected to one end of the bidirectional lead screw 7. The bidirectional lead screw 7 penetrates through the first transverse plate 8 and the second transverse plate 9 and is threadedly connected to the two, and the bidirectional lead screw 7 passes through the activity through groove 4 and is movably connected to the inner wall of the activity through groove 4. In addition, two support rods are fixedly installed on the two side frame plates 6. The two support rods penetrate through the first transverse plate 8 and the second transverse plate 9 and are slidably connected to the two.

[0027] In this method, in order to prevent the driven shaft 11 from rotating in the natural state, a telescopic cylinder 15 is fixedly installed on the second transverse plate 9, and an arc-shaped anti-slip piece 16 is fixedly installed on its output shaft. The inner wall of the arc-shaped anti-slip piece 16 is attached to the outer wall of the driven shaft 11.

[0028] In the pushing mechanism mentioned above, there is a U-shaped frame 18. A unidirectional lead screw 19 is rotatably installed in the U-shaped frame 18. A linkage piece 20 is threadedly installed on the unidirectional lead screw 19. One end of the longitudinal push rod 21 away from the flipping table 1 is fixedly connected to the linkage piece 20. A third driving motor is fixedly installed on the outer wall of one side of the U-shaped frame 18, and its output shaft is fixedly connected to one end of the unidirectional lead screw 19. Two guide rods are fixed in the U-shaped frame 18. The two guide rods penetrate through the linkage piece 20 and are slidably connected to it.

[0029] The working principle of the flipping type tooling for LED display production provided by the utility model is as follows:

[0030] In the initial state, the output shaft of the telescopic cylinder 15 is in the extended state;

[0031] When it is necessary to perform an appearance inspection on the LED display, first place the display on the support panel 3, and then start the first driving motor forward. Its output shaft drives the bidirectional lead screw 7 to rotate. By using its threaded cooperation with the first transverse plate 8 and the second transverse plate 9, the two move towards each other. During the movement, the lower part of the U-shaped frame 12 will move to the lower part of the display. When one side of the display contacts the inner wall of one of the U-shaped frames 12, it will push the display to move until the other side of the display contacts the inner wall of the other U-shaped frame 12. At this time, turn off the first driving motor, and the display is effectively clamped in the horizontal direction. Then rotate the two pressing screws 13 in sequence, and the two pressing pieces 14 start to descend and finally clamp the display from above;

[0032] Then, start two rodless cylinders 5. The sliders on the two rodless cylinders 5 drive the support sliding columns 2 to descend, so that the support panel 3 is separated from the display screen. After that, start the output shaft of the telescopic cylinder 15 to retract, so that the arc-shaped anti-slip piece 16 is separated from the driven shaft 11. Immediately start the second drive motor, and its output shaft drives the driving shaft 10 to rotate, so as to be able to drive the clamped display screen to flip, thus forming a flip-type inspection operation;

[0033] After the inspection of the display screen in the above state is completed, in order to enable the inspector to inspect the part of the display screen in contact with the U-shaped frame 12 and the pressing piece 14, two pressing screws 13 can be rotated first to loosen the display screen. Then, start the third drive motor forward, and its output shaft drives the single lead screw 19 to rotate, so that the linkage piece 20 drives the longitudinal push rod 21 to move. When the pushing piece 22 touches the display screen, it will push the display screen. After pushing it a short distance, start the third drive motor in reverse to bring the pushing piece 22 back to its original position. After that, continue to rotate the pressing screw 13 to fix the display screen again. At this time, the fixing position is changed, and then the flip inspection can be carried out again.

[0034] Compared with the related art, the flip-type tooling for LED display production provided by the present invention has the following beneficial effects:

[0035] The present invention provides a flip-type tooling for LED display production. By providing the U-shaped frame 12 and the pressing piece 14, a reliable and safe fixing method for the LED display screen can be formed. Then, the rotation of the driving shaft 10 drives the display screen to flip to form a flip-type inspection process. Moreover, the setting of the bidirectional lead screw 7 enables the first transverse plate 8 and the second transverse plate 9 to move away from or close to each other, and can clamp and use display screens of different lengths and sizes, with a wide range of applications. In addition, through the push of the pushing piece 22, the position of the display screen can be slightly adjusted, so as to change the position where the pressing piece 14 presses, so that the originally clamped part of the display screen can be revealed to ensure a thorough inspection of the display screen and improve the accuracy of the final inspection result.
