Description

Technical Field

[0001] This invention relates to the field of polarizer measurement technology, and more particularly to a polarizer size measuring device. Background Technology

[0002] Polarizing laser measurement technology utilizes the interaction between a laser and a polarizer to analyze changes in the optical properties of the laser beam after passing through the polarizer, thereby achieving high-precision measurement of key parameters of the polarizer (such as absorption axis angle, transmittance, and optical uniformity). When the polarizer on the conveyor belt passes the laser measuring head, the laser beam perpendicularly illuminates the surface of the polarizer. The receiver detects the change in the position of the reflected light and calculates the thickness using trigonometric relationships.

[0003] When existing polarizer size measuring devices perform laser measurements on polarizers on conveyor belts, the polarizers are relatively lightweight, and sometimes one end of the polarizer moves to the outside of the belt. Current technology cannot push the moved polarizer back onto the belt, and the measuring device cannot accurately align these polarizers, resulting in deviations in laser measurements. At the same time, due to the problem of static electricity generated by friction, the polarizers are easily attracted to the surface of the conveyor belt, affecting the alignment position and subsequent material unloading, thus affecting the calculation result of the overall polarizer thickness.

[0004] In summary, the existing technology lacks a technique for resetting polarizers that have moved out of the belt. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a polarizer size measuring device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a polarizer size measuring device, including a mounting base, a conveyor belt mounted on the mounting base, a top frame fixedly connected to the mounting base, two laser measuring heads mounted on the top frame, two cleaning mechanisms fixedly connected to the top frame at the position of the laser measuring heads, a movable seat slidably mounted on the top frame, an adjusting frame below the movable seat, and a reset mechanism rotatably connected to one side of the adjusting frame, the reset mechanism including a polarizer reset plate.

[0007] Preferably, toothed plates are fixedly connected to both sides of the mounting base, and a movable frame is slidably fitted on the mounting base. An electrostatic eliminator is installed on one end of the movable frame located inside the conveyor belt. Rollers are frictionally driven at both ends of the conveyor belt. One of the rollers passes through the mounting base and is fixedly connected to a concave-convex disc at both ends. The concave-convex disc is slidably contacted with one end of the movable frame.

[0008] Preferably, the cleaning mechanism includes a fixed frame, the top of which is fixedly connected to a top frame, a rotating frame is rotatably connected to the fixed frame, a sponge is fixedly connected to the rotating frame, the sponge is slidably in contact with the laser measuring head lens, and a driven wheel is fixedly connected to the top of the rotating frame.

[0009] Preferably, the sponge has a self-cleaning ring that slides on it, and a connecting rod assembly is rotatably connected to the bottom end of the self-cleaning ring. The other end of the connecting rod assembly is rotatably connected to a rotating frame. A gear is fixedly connected to one end of the connecting rod assembly connected to the rotating frame. A rack is meshed with the gear on one side, and the rack is slidably engaged with the rotating frame. A ring groove plate is fixedly connected to the bottom end of the fixed frame, and one end of the rack is slidably connected to the inner wall of the ring groove plate.

[0010] Preferably, the movable seat is threadedly connected to a lead screw, which is rotatably connected to the top frame. Two drive wheels are fixedly connected to one end of the lead screw near the laser measuring head, and the drive wheels mesh with the driven wheels for transmission. The other end of the lead screw passes through the top frame and is fixedly connected to a motor A, which is fixedly installed to the top frame.

[0011] Preferably, a hydraulic rod is fixedly connected to the adjusting frame, the top end of the hydraulic rod passes through the movable seat and is fixedly connected to a motor B, and an anti-fall plate is fixedly connected to one side of the adjusting frame.

[0012] Preferably, one side of the plate reset plate is rotatably connected to the adjustment frame, the top of the plate reset plate is fixedly connected to an adjustment wheel, one side of the adjustment wheel is engaged with an adjustment rack, and the adjustment rack is slidably engaged with the adjustment frame.

[0013] Preferably, a connecting rod is rotatably connected to one end of the adjusting rack, and a moving block is rotatably connected to the other end of the connecting rod. A threaded rod is threadedly connected to the moving block, and the threaded rod is rotatably connected to the adjusting frame. A universal joint is fixedly connected to the bottom end of the threaded rod, and the universal joint is rotatably connected to the adjusting frame. A transmission wheel is fixedly connected to the other end of the universal joint, and the transmission wheel meshes with the rack plate for transmission.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention effectively solves the problem of polarizers falling off the conveyor belt. The reset mechanism automatically pushes the polarizer back onto the conveyor belt, ensuring that the polarizer does not fall off and remains within the laser measurement range. This guarantees the accuracy of the laser measurement, improves the automation level of the measuring device, reduces manual intervention, increases measurement efficiency, and reduces errors and downtime during transportation.

[0016] By setting up a cleaning mechanism, the sponge will rotate and wipe the laser measuring head lens while the moving reset mechanism is in operation. This prevents the lens from being affected by dust and thus avoids affecting the laser measurement. At the same time, the self-cleaning ring can effectively prevent the sponge surface from accumulating dust and thus reduce the wiping efficiency, ensuring that each wipe achieves a cleaning effect.

[0017] By installing an electrostatic eliminator on the movable frame, the conveyor belt can move the movable frame up and down while transporting the polarizer. When moving up, it eliminates static electricity near the polarizer, and when moving down, it eliminates residual static electricity on the lower surface of the conveyor belt, preventing static adsorption problems during polarizer transport. The up-and-down static elimination process also avoids excessive accumulation of ions in local areas. Attached Figure Description

Detailed Implementation

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1-8 The polarizer size measuring device shown includes a mounting base 1, a conveyor belt 2 mounted on the mounting base 1, a top frame 3 fixedly connected to the mounting base 1, two laser measuring heads 4 mounted on the top frame 3, two cleaning mechanisms 5 fixedly connected to the top frame 3 at the position of the laser measuring heads 4, a movable seat 6 slidably mounted on the top frame 3, an adjusting frame 7 below the movable seat 6, and a reset mechanism 8 rotatably connected to one side of the adjusting frame 7, the reset mechanism 8 including a film reset plate 801.

[0029] like Figure 3 , Figure 4 As shown, toothed plates 101 are fixedly connected to both sides of the mounting base 1. A movable frame 102 is slidably fitted onto the mounting base 1. An electrostatic eliminator 103 is installed on one end of the movable frame 102 located inside the conveyor belt 2. Rollers 201 are frictionally driven at both ends of the conveyor belt 2. One of the rollers 201 passes through the mounting base 1 at both ends and is fixedly connected to a convex-concave disc 202. The convex-concave disc 202 is slidably contacted with one end of the movable frame 102. When the conveyor belt 2 rotates, the rotation of one of the rollers 201 drives the connected convex-concave disc 202 to rotate, thereby lifting the movable frame 102. This causes the electrostatic eliminator 103 on the movable frame 102 to move upward and closer to the polarizer, thereby eliminating static electricity near the polarizer. When it moves downward, it eliminates residual static electricity on the lower surface of the conveyor belt 2, preventing static electricity adsorption during polarizer transport.

[0030] like Figure 5As shown, the cleaning mechanism 5 includes a fixed frame 501, the top of the fixed frame 501 is fixedly connected to the top frame 3, a rotating frame 502 is rotatably connected to the fixed frame 501, a sponge 503 is fixedly connected to the rotating frame 502, the sponge 503 is slidably contacted with the lens of the laser measuring head 4, and a driven wheel 504 is fixedly connected to the top of the rotating frame 502.

[0031] A self-cleaning ring 505 is slidably connected to the sponge 503. A connecting rod assembly 506 is rotatably connected to the bottom end of the self-cleaning ring 505. The other end of the connecting rod assembly 506 is rotatably connected to the rotating frame 502. A gear 507 is fixedly connected to the end of the connecting rod assembly 506 connected to the rotating frame 502. A rack 508 is meshed with the gear 507 on one side, and the rack 508 is slidably engaged with the rotating frame 502. A ring groove plate 509 is fixedly connected to the bottom end of the fixed frame 501, and one end of the rack 508 slides against the inner wall of the ring groove plate 509. The rotating frame 502 drives the sponge 503 to rotate, wiping the lens of the laser measuring head 4. When the sponge 503 leaves the lens of the laser measuring head 4, the ring groove plate 509 drives the rack 508 to reciprocate, causing the rack 508 to drive the connecting rod assembly 506 connected to the gear 507 to reciprocate, which in turn drives the self-cleaning ring 505 to reciprocate.

[0032] like Figure 6 As shown, a lead screw 601 is threadedly connected to the movable base 6. The lead screw 601 is rotatably connected to the top frame 3. Two drive wheels 602 are fixedly connected to one end of the lead screw 601 near the laser measuring head 4. The drive wheels 602 mesh with the driven wheels 504 for transmission. The other end of the lead screw 601 passes through the top frame 3 and is fixedly connected to a motor A603. The motor A603 is fixedly installed to the top frame 3. When the lead screw 601 rotates, it drives the connected drive wheels 602 to rotate, which in turn drives the rotating frame 502 connected to the driven wheels 504 to rotate.

[0033] like Figure 7 As shown, a hydraulic rod 701 is fixedly connected to the adjustment frame 7. The top end of the hydraulic rod 701 passes through the movable seat 6 and is fixedly connected to a motor B702. A fall prevention plate 703 is fixedly connected to one side of the adjustment frame 7. The motor B702 drives the adjustment frame 7 to rotate, causing the film reset plate 801 to rotate to the side of the removed polarizer.

[0034] like Figure 8 As shown, the plate reset plate 801 is rotatably connected to the adjustment frame 7 on one side, and the top of the plate reset plate 801 is fixedly connected to the adjustment wheel 802. The adjustment wheel 802 is meshed with the adjustment rack 803 on one side, and the adjustment rack 803 is slidably engaged with the adjustment frame 7.

[0035] By using the reset mechanism 8 in conjunction with laser measurement technology, the problem of the polarizer moving out of the conveyor belt 2 can be effectively solved. The function of the reset mechanism 8 is to automatically push the moved polarizer back onto the conveyor belt 2, which not only ensures that the polarizer will not fall off, but also ensures that the polarizer is within the laser measurement range, thereby ensuring the accuracy of laser measurement, improving the automation level of the measurement device, reducing manual intervention, improving resource utilization efficiency, and reducing errors and downtime during transportation.

[0036] One end of the adjusting rack 803 is rotatably connected to a connecting rod 804, and the other end of the connecting rod 804 is rotatably connected to a moving block 805. A threaded rod 806 is threadedly connected to the moving block 805. The threaded rod 806 is rotatably connected to the adjusting frame 7. A universal joint 807 is fixedly connected to the bottom end of the threaded rod 806. The universal joint 807 is rotatably connected to the adjusting frame 7. A transmission wheel 808 is fixedly connected to the other end of the universal joint 807. The transmission wheel 808 meshes with the gear plate 101 for transmission. When the transmission wheel 808 meshes with the toothed plate 101, it will drive the transmission wheel 808 to rotate. At this time, the transmission wheel 808 will drive the threaded rod 806 connected to the universal joint 807 to rotate, which will cause the threaded rod 806 to drive the moving block 805 to move, which will cause the moving block 805 to drive the connecting rod 804, which will cause the connecting rod 804 to drive the adjusting rack 803 to move. At this time, the adjusting rack 803 will drive the plate reset plate 801 connected to the adjusting wheel 802 to rotate.

[0037] The overall operation process is as follows: When transporting the polarizer using the conveyor belt 2, the thickness of the polarizer on the conveyor belt 2 is measured using the laser measuring head 4; by adjusting the position and height of the moving seat 6 and the adjusting frame 7, the film reset plate 801 is positioned on the side where the polarizer has moved out; at the same time, when the adjusting frame 7 moves down, it will drive the film reset plate 801 to rotate, thereby pushing the end of the polarizer that has moved out back onto the conveyor belt 2, ensuring that it does not fall off during transport and remains within the range of laser measurement.

[0038] Working principle: When it is necessary to transport polarizers, the conveyor belt 2 is used to transport the polarizers. When a polarizer is removed from the conveyor belt 2, the motor B702 first drives the adjusting frame 7 to rotate, so that the film reset plate 801 rotates to the side of the removed polarizer. Then, the motor A603 drives the lead screw 601 to rotate, so that the lead screw 601 drives the moving seat 6 to move to the appropriate position. Then, the hydraulic rod 701 drives the adjusting frame 7 to move down, so that the anti-fall plate 703 blocks the other side of the removed polarizer.

[0039] Then, when the transmission wheel 808 meshes with the toothed plate 101, it will drive the transmission wheel 808 to rotate. At this time, the transmission wheel 808 will drive the threaded rod 806 connected to the universal joint 807 to rotate, so that the threaded rod 806 will drive the moving block 805 to move, so that the moving block 805 will drive the connecting rod 804, so that the connecting rod 804 will drive the adjusting rack 803 to move. At this time, the adjusting rack 803 will drive the plate reset plate 801 connected to the adjusting wheel 802 to rotate, pushing the removed polarizer back onto the conveyor belt 2.

[0040] Then, the laser measuring head 4 is used to perform laser measurement on the polarizer on the conveyor belt 2. When the conveyor belt 2 rotates, one of the rollers 201 rotates, which drives the connected convex and concave discs 202 to rotate, thereby lifting the movable frame 102 and causing the static eliminator 103 on the movable frame 102 to move upward. The static eliminator 103 is an ion wind bar type static eliminator. The discharge needle generates corona discharge through a high voltage power supply, ionizing the surrounding air to generate positive and negative ions, which can eliminate static electricity through the surface of the conveyor belt. When it is close to the polarizer, it can eliminate the static electricity on the surface of the polarizer. When it moves downward, it eliminates the residual static electricity on the lower surface of the conveyor belt, preventing the problem of adhering to the surface of the conveyor belt 2. In the up-and-down static elimination, it also avoids the excessive accumulation of ions in local areas.

[0041] Simultaneously, when the lead screw 601 rotates, it drives the connected drive wheel 602 to rotate, which in turn drives the driven wheel 504 to rotate the rotating frame 502. The rotating frame 502 then drives the sponge 503 to rotate, wiping the lens of the laser measuring head 4. When the sponge 503 leaves the lens of the laser measuring head 4, the annular groove plate 509 drives the rack 508 to reciprocate, causing the rack 508 to drive the connecting rod group 506 connected to the gear 507 to reciprocate, which in turn drives the self-cleaning ring 505 to reciprocate, allowing the dust inside the sponge 503 to be discharged, ensuring its cleaning quality.
