Description

TECHNICAL FIELD

[0002] The full name of the polarizer is polarized light sheet, and imaging of a liquid crystal display must rely on the polarized light sheet. All liquid crystals have front and back two polarized light sheets closely attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. If any one polarized light sheet is missing, the liquid crystal sheet cannot display an image. After the production of the polarized light sheet is completed, the polarized light sheet needs to be packaged and handled,

[0048] In this embodiment, the preferred embodiment is... Figure 7 The position of the piston head 58 is the initial position. When the air pump draws air from the second intake pipe 52, negative pressure acts on the inside of the cylinder 51. Since the through hole 591 is located at the position of the first connecting pipe 53, the baffle 59 blocks the second connecting pipe 54 and the third connecting pipe 55. At this time, the negative pressure acts on the third telescopic rod 21 through the first connecting pipe 53, and the third telescopic rod 21 retracts. At this time, the third spring 2111 is compressed. When the third telescopic rod 21 retracts to its maximum stroke, the air pump continues to draw air until the negative pressure is greater than the tension of the second spring 57. At this time, the piston head 58 moves towards... Figure 7 The piston head 58 moves to the right, causing the baffle 59 to move until the through hole 591 moves to the position of the second connecting pipe 54. At this time, the negative pressure acts on the first telescopic rod 23 through the second connecting pipe 54, causing the first telescopic rod 23 to retract. At this time, the fourth spring 231 is compressed until the first telescopic rod 23 retracts to its maximum stroke. At this time, the air pump continues to draw air until the negative pressure is greater than the tension of the second spring 57. At this time, the piston head 58 moves to the right. Figure 7Move to the right until the through hole 591 moves to the position of the third connecting pipe 55. At this time, the baffle 59 blocks the second connecting pipe 54 and the first connecting pipe 53. At this time, the negative pressure acts on the second telescopic rod 43 through the third connecting pipe 55, and the second telescopic rod 43 retracts. At this time, the fifth spring 432 is compressed.

[0049] When the piston head 58 needs to return to its initial position, the air pump continues to draw air from inside the second suction pipe 52. The movement of the piston head 58 causes the baffle 59 to move until the baffle 59 touches the ground. Figure 7 On the right inner wall of the cylinder body 51, with the first connecting pipe 53, the second connecting pipe 54, and the third connecting pipe 55 located to the left of the piston head 58, the electric valve 56 is opened, and air enters the cylinder body 51 from the position of the electric valve 56. The air enters the first connecting pipe 53, the second connecting pipe 54, and the third connecting pipe 55 respectively. Air enters the third telescopic rod 21 from the first connecting pipe 53, and the negative pressure inside the third telescopic rod 21 is lost. Under the elastic force of the third spring 2111, the third spring 2111 pushes the receiving shell 12 to move, and the third telescopic rod 21 extends and returns to its original position. Air enters from the second connecting pipe 54. The first telescopic rod 23 loses its negative pressure. Under the elastic force of the fourth spring 231, the fourth spring 231 pushes the movable plate 22 to move, and the first telescopic rod 23 extends and returns to its original position. Air enters the second telescopic rod 43 from the third connecting pipe 55. The second telescopic rod 43 loses its negative pressure. Under the elastic force of the fifth spring 432, it pushes the toothed plate 42 to move, and the second telescopic rod 43 extends and returns to its original position. Finally, the interface of the air pump and the second suction pipe 52 is opened, and air enters the cylinder 51 from the second suction pipe 52. Under the pulling force of the second spring 57, the piston head 58 returns to its original position. Figure 7 After reaching the middle position, close the electric valve 56.

[0050] During operation, polarizing films are stacked on top of the base plate 33 and located inside the material frame 34. By connecting the suction pipe 13 to the existing negative pressure pump, the negative pressure pump generates negative pressure, which acts on the suction cup 11 through the suction pipe 13 and the housing 12 to adsorb the polarizing films.

[0051] Simultaneously, when air is drawn from the second intake pipe 52 by the air pump, negative pressure is applied to the inside of the cylinder 51. Since the through hole 591 is located at the position of the first connecting pipe 53 at this time, the baffle 59 blocks the second connecting pipe 54 and the third connecting pipe 55. At this time, the negative pressure is applied to the third telescopic rod 21 through the first connecting pipe 53. The third telescopic rod 21 retracts. When the third telescopic rod 21 retracts, it can drive the housing 12 to rise, thereby driving the polarizer to rise.

[0052] When the third telescopic rod 21 retracts to its maximum stroke, the air pump continues to draw in air until the negative pressure exceeds the tension of the second spring 57. At this point, the piston head 58 moves towards... Figure 7The piston head 58 moves to the right, causing the baffle 59 to move until the through hole 591 moves to the position of the second connecting pipe 54. At this time, the negative pressure acts on the first telescopic rod 23 through the second connecting pipe 54, causing the first telescopic rod 23 to retract. When the first telescopic rod 23 moves, it can drive the movable plate 22 to move. The movable plate 22 drives the third telescopic rod 21 to move. The third telescopic rod 21 drives the housing 12, suction cup 11 and polarizer to move. When the predetermined packaging position is reached, the negative pressure pump stops working and the polarizer is lowered.

[0053] At this point, the fourth spring 231 is compressed until the first telescopic rod 23 retracts to its maximum stroke. The air pump continues to draw in air until the negative pressure exceeds the tension of the second spring 57. At this point, the piston head 58 moves towards... Figure 7 The plate moves to the right until the through hole 591 moves to the position of the third connecting pipe 55. At this time, the baffle 59 blocks the second connecting pipe 54 and the first connecting pipe 53. At this time, the negative pressure acts on the second telescopic rod 43 through the third connecting pipe 55, and the second telescopic rod 43 retracts. When the second telescopic rod 43 retracts, the toothed plate 42 moves towards the right. Figure 3 When the gear moves to the right, the toothed plate 42 drives the first gear 41 to rotate, the first gear 41 drives the rotating shaft 312 to rotate, and the rotating shaft 312 drives the second flat ratchet 3121 to rotate in the same direction as the first flat ratchet 315. At this time, the second flat ratchet 3121 cannot drive the first flat ratchet 315 to rotate.

[0054] At this point, the first stage of the operation is complete. When the piston head 58 returns to its initial position, and the air pump continues to draw air from the second suction pipe 52, the movement of the piston head 58 causes the baffle 59 to move until the baffle 59 touches the ground. Figure 7 On the right inner wall of the cylinder body 51, the first connecting pipe 53, the second connecting pipe 54, and the third connecting pipe 55 are located to the left of the piston head 58. When the electric valve 56 is opened, air enters the cylinder body 51 from the position of the electric valve 56. The air enters the first connecting pipe 53, the second connecting pipe 54, and the third connecting pipe 55 respectively. The air enters the third telescopic rod 21 from the first connecting pipe 53. The negative pressure inside the third telescopic rod 21 is lost. Under the elastic force of the third spring 2111, the third spring 2111 pushes the receiving shell 12 to move, and the third telescopic rod 21 extends and returns to its original position. Air enters the first telescopic rod 23 from the second connecting pipe 54. The negative pressure inside the first telescopic rod 23 is lost. Under the elastic force of the fourth spring 231, the fourth spring 231 pushes the movable plate 22 to move, and the first telescopic rod 23 extends and returns to its original position. At this time, the polarizer inside the material frame 34 is below the suction cup 11.
