Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figures 1 to 3This embodiment provides a positioning rod device for preventing polarizer film from being crushed during transport, including a limiting component 1 and an alarm component 2. The limiting component 1 includes a guide rail 11, a slider 12, a first spring 13, a support block 14, a fixing block 15, and a positioning rod 16. The slider 12 and the support block 14 are slidably connected to the guide rail 11. The slider 12 is fixedly connected to one end of the first spring 13, and the other end of the first spring 13 is fixedly connected to the support block 14. The support block 14 is fixedly connected to the fixing block 15, and the positioning rod 16 is rotatably connected to the fixing block 15. The slider 12, the first spring 13, the support block 14, the fixing block 15, and the positioning rod 16 are arranged in two sets and are symmetrically arranged.

[0027] Preferably, in this embodiment, the slider 12 and the support block 14 can slide on the guide rail 11. When the position of the support block 14 is fixed, the support block 14 can support the first spring 13. When the polarizer passes the positioning rod 16, the polarizer presses against the positioning rod 16. The positioning rod 16 applies pressure to the slider 12 through the fixing block 15. The slider 12 compresses the first spring 13, absorbing the force of the polarizer and preventing damage to the polarizer during transportation.

[0028] The alarm component 2 includes a limiting block 21, a first electrode plate 22, a second electrode plate 23, a power supply 24, and an audible and visual alarm 25. The limiting block 21 is fixedly connected to the guide rail 11. The first electrode plate 22 is provided on the limiting block 21. The second electrode plate 23 is provided on the slider 12 corresponding to the first electrode plate 22. The first electrode plate 22, the second electrode plate 23, the power supply 24, and the audible and visual alarm 25 are connected in series.

[0029] In this embodiment, the power supply 24 preferably uses an existing battery. When the polarizer's transport itself has a large offset, as the polarizer passes the positioning rod 16, the polarizer squeezes the positioning rod 16. The positioning rod 16 applies pressure to the slider 12 through the fixing block 15. The slider 12 compresses the first spring 13 to absorb the force of the polarizer until the slider 12 touches the limiting block 21. At this time, the slider 12 is fixed in position, and the second electrode plate 23 on the slider 12 contacts the first electrode plate 22 on the limiting block 21. The first electrode plate 22, the second electrode plate 23, the power supply 24, and the audible and visual alarm 25 form a circuit, and the audible and visual alarm 25 sounds an alarm to remind the staff to handle the situation. When the polarizer's offset is small, the position of the polarizer can be calibrated by the elastic force of the first spring 13, and the polarizer presses the positioning rod 16. The positioning rod 16 applies pressure to the slider 12 through the fixing block 15. The slider 12 compresses the first spring 13 to absorb the force of the polarizer and prevent damage to the polarizer, which could lead to damage during transport. When the polarizer's offset is large, an alarm can be automatically issued to remind the staff to handle the situation.

[0030] Example 2

[0031] Reference Figures 1 to 8This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

[0032] The slider 12 is fixedly connected to one end of the telescopic rod 17, and the other end of the telescopic rod 17 is fixedly connected to the support block 14. The first spring 13 is sleeved on the telescopic rod 17.

[0033] In this preferred embodiment, the telescopic rod 17 can limit the first spring 13 to prevent it from becoming scattered when compressed.

[0034] Reference Figure 4 The support block 14 has a cavity 141 inside. The bottom wall of the cavity 141 is fixedly connected to one end of the second spring 142. The other end of the second spring 142 is fixedly connected to the movable plate 143. The movable plate 143 is fixedly connected to one end of the fixed column 144. The other end of the fixed column 144 contacts the guide rail 11.

[0035] In this preferred embodiment, under the action of the second spring 142, the movable plate 143 is pushed towards... Figure 4 The moving plate 143 moves upward, causing the fixed column 144 to move. The fixed column 144 presses against the guide rail 11, automatically locking the position of the support block 14 on the guide rail 11.

[0036] Reference Figure 1 It also includes a drive component 3, which includes a telescopic member 31, an interface tube 32 and a first fixed tube 33. The telescopic member 31 is connected to the interface tube 32, and both ends of the telescopic member 31 are fixedly connected to one end of the first fixed tube 33, and the other end of the first fixed tube 33 is fixedly connected to the support block 14.

[0037] In this preferred embodiment, the interface pipe 32 is connected to an existing blow-suction dual-purpose air pump. When the air pump blows air into the telescopic member 31 through the interface pipe 32, the telescopic member 31 extends. The telescopic member 31 moves the support block 14 through the first fixed pipe 33. At this time, the distance between the two positioning rods 16 increases, which can guide and position larger polarizers. When the blow-suction dual-purpose air pump sucks air into the telescopic member 31 through the interface pipe 32, the telescopic member 31 shortens. The telescopic member 31 moves the support block 14 through the first fixed pipe 33. At this time, the distance between the two positioning rods 16 decreases, which can guide and position smaller polarizers. This method can guide and position polarizers of different sizes, is easy to adjust, and is convenient to use.

[0038] Reference Figure 5 The telescopic component 31 includes a fixed cylinder 311, a movable tube 312, and a piston head 313. The piston head 313 is slidably connected to the inner wall of the fixed cylinder 311. The piston head 313 is fixedly connected to the movable tube 312. The movable tube 312 is connected to the first fixed tube 33. The fixed cylinder 311 is connected to the interface tube 32.

[0039] In this preferred embodiment, the interface pipe 32 is connected to an existing blow-and-suction dual-purpose air pump. When the air pump blows air into the fixed cylinder 311 through the interface pipe 32, the air pressure inside the fixed cylinder 311 and the movable pipe 312 increases. The movable pipe 312 extends out of the fixed cylinder 311, and the piston head 313 facilitates smoother sliding of the movable pipe 312.

[0040] The movable tube 312 drives the support block 14 to move through the first fixed tube 33. At this time, the distance between the two positioning rods 16 increases, which can guide and position the larger polarizer.

[0041] Furthermore, when the blow-and-suction air pump blows air into the fixed cylinder 311 through the interface pipe 32, the air pressure inside the fixed cylinder 311 and the movable pipe 312 decreases. The movable pipe 312 retracts into the fixed cylinder 311, and the movable pipe 312 drives the support block 14 to move through the first fixed pipe 33. At this time, the distance between the two positioning rods 16 becomes smaller, which can guide and position smaller polarizers. It can guide and position polarizers of different sizes, is easy to adjust, and is convenient to use.

[0042] Reference Figures 4 to 8 The first fixing tube 33 is connected to one end of the second fixing tube 34, the other end of the second fixing tube 34 is connected to one end of the third fixing tube 35, and the other end of the third fixing tube 35 is connected to the cavity 141.

[0043] The inner wall of the second fixed tube 34 is slidably connected to the movable cylinder 36, and the movable cylinder 36 is provided with a first through hole 361 and a second through hole 362.

[0044] In this preferred embodiment, the interface pipe 32 is connected to an existing blow-and-suction dual-purpose air pump. When the air pump blows air into the fixed cylinder 311 through the interface pipe 32, the air pressure inside the fixed cylinder 311 and the movable pipe 312 increases. At this time, the movable cylinder 36 is pushed to the position... Figure 8 At this position, the movable cylinder 36 blocks the third fixed pipe 35, preventing air from entering the third fixed pipe 35. Meanwhile, the air inside the movable pipe 312 will enter the area above the movable plate 143 through the first fixed pipe 33 (see reference). Figure 4 Air pushes the movable plate 143 downward. At this time, the movable plate 143 moves downward against the elastic force of the second spring 142. The fixed column 144 of the movable plate 143 moves and disengages from the guide rail 11, releasing the position lock of the support block 14 on the guide rail 11. Then the movable tube 312 extends out from the fixed cylinder 311. The movable tube 312 drives the support block 14 to move through the first fixed tube 33. At this time, the distance between the two positioning rods 16 increases, which can guide and position the larger polarizer.

[0045] Furthermore, when the blow-and-suction dual-purpose air pump blows air into the fixed cylinder 311 through the interface pipe 32, the air pressure inside the fixed cylinder 311 and the movable pipe 312 decreases, and the movable cylinder 36 is pulled to the position of Figure 7 In the middle position, the movable cylinder 36 blocks the first fixed tube 33, isolating the first fixed tube 33 on the left side of the movable cylinder 36. At this time, the first through hole 361 is aligned with the third fixed tube 35, as shown in the reference. Figure 4 As the air pressure below the movable plate 143 decreases, it pulls the movable plate 143 downwards. At this time, the movable plate 143 moves downwards against the elastic force of the second spring 142. The movable plate 143 drives the fixed column 144 to move, and the fixed column 144 disengages from the guide rail 11, releasing the locking of the support block 14 on the guide rail 11. Then, the movable tube 312 retracts into the fixed cylinder 311. The movable tube 312 drives the support block 14 to move through the first fixed tube 33. At this time, the distance between the two positioning rods 16 becomes smaller, which can guide and position smaller polarizers. It can guide and position polarizers of different sizes, is easy to adjust, and is convenient to use.

[0046] The outer wall of the movable cylinder 36 has a square cross-section, and the inner wall of the second fixed tube 34 is arranged corresponding to the movable cylinder 36.

[0047] In this embodiment, it is preferred to prevent relative rotation between the movable cylinder 36 and the second fixed tube 34.

[0048] The movable cylinder 36 is fixedly connected to one end of the first fixing rod 37, the other end of the first fixing rod 37 is fixedly connected to one end of the second fixing rod 38, the other end of the second fixing rod 38 is fixedly connected to the third fixing rod 39, and the third fixing rod 39 is slidably connected to the third through hole 331 on the first fixing tube 33.

[0049] In this preferred embodiment, when the blow-and-suction dual-purpose air pump blows air into the fixed cylinder 311 through the interface pipe 32, the air pressure inside the fixed cylinder 311 and the movable pipe 312 decreases, and the movable cylinder 36 is pulled to the position of Figure 7 Simultaneously, the movable cylinder 36 moves the first fixed rod 37, which in turn moves the third fixed rod 39 upward via the second fixed rod 38, reaching the desired position. Figure 7At the indicated position, the third fixing rod 39 is pulled out from the third through hole 331. The air pressure inside the cavity 141 above the first fixing tube 33 and the movable tube 312 on the left side of the movable cylinder 36 is the same as the external atmospheric pressure. This allows the movable plate 143 to move downwards after the air pressure below it decreases. At this time, the movable plate 143 moves downwards against the elastic force of the second spring 142, and the fixing column 144 of the movable plate 143 moves, disengaging from the guide rail 11 and releasing the locking of the support block 14 on the guide rail 11. Then, the movable tube 312 retracts into the fixing cylinder 311, and the movable tube 312 drives the support block 14 to move through the first fixing tube 33. At this time, the distance between the two positioning rods 16 becomes smaller, which can guide and position smaller polarizers. It can guide and position polarizers of different sizes, is easy to adjust, and is convenient to use.
