The working principle of the present invention is: before working, the components of the present application can be arranged as follows: the frame 5 is fixed on one side of the common conveyor belt 1, the lifting mechanism 3 is fixed on the frame 1 through the lifting mechanism fixing seat 24, and the clamp The fixing plate 19 of the tightening and turning mechanism is welded to the lower end of the lifting column 24 , and the clamping and turning mechanism 3 is located above the ordinary conveyor belt 1 , so that the front ends of the two rectangular tubes 11 are located directly above the ordinary conveyor belt 1 .

The present invention is designed for small and medium-sized articles, and a display is taken as an example to illustrate the working principle. The ordinary conveyor 1 stops when the custom tray 2 with the display reaches the designated position, and the output servo motor II 20-2 starts, which drives the gear 28 to rotate, and the gear 28 is meshed with the gear 28. The downward movement of 27, because the rack 27 is fixed on the lifting column 26 of the lifting mechanism 4, the linear guide rails II8-2 are fixed on both sides of the lifting column 26, and the slider II18-2 is fixed on the lifting mechanism fixing plate 24, thereby lifting and lowering The column 26 can move downward along the direction of the guide rail II8-2, and because the lifting column 26 is welded on the fixing plate 19 of the clamping and turning mechanism, the lifting column 26 can drive the clamping and turning mechanism 3 to move down together; When all the rollers of the bearing roller (IKO-CF6B) 14 touch the display screen on the customized tray 2, the output motor II 20-2 stops running. At this time, the uneven display in the tray has been placed on the bearing roller (IKO-CF6B) 14. The roller is smoothed (the smoothing is to make the front of the display screen level); the output servo motor I20-1 is activated, the bidirectional lead screw 22 rotates, and the two lead screw nuts 23 are driven to move in the center, and the two ends of the slider connecting plate 17 are fixed with The slider I18-1, and then the screw nut 23 can drive the two slider connecting plates 17 to achieve centering movement along the linear guide rail I8-1, and because the rear ends of the two rectangular tubes 11 are respectively fixed on the two sliders The bottom surface of the connecting plate 17, so that when the sliding block connecting plate 17 moves in the center, the two rectangular tubes 11 also realize the centering movement. There are clamping strips 13 (rubber) and rollers with bearings 14 (IKO-CF6B). The front end of the right rectangular tube 11 is fixed with a rotary cylinder 15, and the rotating shaft of the rotary cylinder 15 is fixed with clamping strips 13 (rubber) and bearings. Roller (IKO-CF6B) 14, when the two rectangular tubes 11 are centered, make the clamping strips 13 (rubber) on the left and right sides contact the left and right sides of the display, and after firmly clamping the left and right sides of the display, the output motor I20- 1 Stop the movement. At this time, due to the power-off locking of the brake 12 and the holding effect of the rotating cylinder 15, the clamping strips 13 (rubber) on the left and right sides are in a fixed role, and are firmly held by the clamping strips 13 (rubber) on the left and right sides. The clamped monitor is also in a fixed state;

The output motor II 20-2 starts in the reverse direction, the lifting mechanism 4 moves upward, and drives the clamping and flipping mechanism 3 of the clamped display to move upward. After moving to a certain height, the output motor II 20-2 stops moving; The brake 12 is energized and released, the rotating shaft of the holding brake 12 is changed from fixed to a driven rotational movement, and the clamping strip 13 (rubber) fixed on the rotating shaft of the holding brake 12 is also changed from fixed to a rotational movement. The rotary cylinder 15 at the front end of the right rectangular tube 11 starts to rotate, and the clamping strip 13 (rubber) fixed on the rotating shaft of the rotary cylinder 15 also rotates. Since the left clamping strip 13 (rubber) can rotate at this time, the display It is firmly clamped by the clamping strips 13 (rubber) on the left and right sides, and then the display also rotates in the same direction with the rotating cylinder 15. After the display is turned over to a certain angle, the rotating cylinder 15 stops moving and the display also stops. At the same time, other devices can process or detect the display.

When the display processing or inspection is completed, the rotating cylinder 15 moves in the reverse direction, and the right clamping strip 13 (rubber) also moves in the reverse direction with the rotating cylinder 15. Since the left clamping strip 13 (rubber) is in a free state at this time, it will also move from When the rotary cylinder 15 rotates to the zero-degree position, the rotary cylinder 15 stops moving, and at the same time, the brake 12 at the front end of the left rectangular tube 11 loses power and locks, restricting the free rotation of the left clamping strip 13 (rubber). ;The output motor II20-2 starts, the lifting mechanism 4 drives the clamping and flipping mechanism 3 to move down, and when the display touches the tray, the output motor II20-2 stops moving; at this time, the output motor I20-1 moves in the opposite direction, and the rectangles on the left and right sides are The tube 11 starts to move to both sides, and the clamping strip 13 (rubber) slowly loosens the display. After the clamping strip 13 (rubber) completely loosens the display, the output motor I20-1 stops moving; at this time, the output motor II20-2 In reverse motion, the lifting mechanism 4 drives the clamping and flipping mechanism 3 to move upward. After returning to the original position, the motor II 20-2 stops moving, and the ordinary conveyor 1 carries away the customized tray 2 with the processed or inspected display.

In the movement of the clamping and turning mechanism 3 described above, the cooperation of the two-way screw 22 and the screw nut 23 enables the screw to drive the screw nut 23 to move in both positive and negative directions; the slider I18-1 and the linear The cooperation of the guide rail II8-1 can realize the linear movement of the slider I18-1 along the linear guide rail II8-1; the screw nut 23 is fixed on the slider connecting plate 17, and the two ends of the slider connecting plate 17 are fixed with the slider I18 -1, the rear end of the rectangular tube 11 is fixed on the bottom of the slider connecting plate 17, the linear guide I8-1 is fixed on the fixing plate 19 of the clamping and turning mechanism, and the movement of the two-way screw 22 can be achieved through the cooperation of various components. The centering movement of the two rectangular tubes 11 is realized; the front end of the rectangular tube 11 on the left is fixed with the brake 12, the front end of the rectangular tube 11 on the right is fixed with the rotary cylinder 15, and the clamping bar 13 ( Rubber) and rollers with bearing (IKO-CF6B) 14, through the power-on release of the holding brake 12, the power-off locking, and the positive and negative movement of the rotating cylinder 15, the display can be rotated forward and backward. Due to the action of the two-way screw 22, the clamping part of this structure can realize the movement of two opposite directions running at the same time and ending at the same time. As long as a certain safety distance is set, it is easy to control the left and right clamping bars 13 (rubber ) movement to avoid damage to the display during the clamping process; the power-on release of the brake 12, and the power-off locking, precedes the positive and negative movement of the rotary cylinder 15, and the rotary cylinder can only receive the signal after the brake 12 receives the signal. signal, the display will not be damaged due to the problem of signal reception speed during the flipping process. Therefore, the present invention is very suitable for the processing and inspection of similar displays or fragile items.

The specific embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, and can also be made within the scope of knowledge possessed by those of ordinary skill in the art without departing from the purpose of the present invention.
