[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7This utility model provides a technical solution: a bubble detection device for polarizers that is easy to detect, including a conveying module 1, a detection module 2 connected to the top of the conveying module 1, a linear module 3, and an adjusting device 8. One side of the linear module 3 is connected to one side of the conveying module 1, and the moving part of the linear module 3 is connected to a support plate 6. An electric push rod 5 is fixedly installed on the top of the support plate 6. The push rod 5 passes through the support plate 6 and is connected to a suction cup. The adjusting device 8 is installed on one side of the conveying module 1, and the top of the conveying module 1 is provided with a leveling device 7. The alignment device 7 includes two connecting blocks 715 and two side grooves 717. Connecting rods 716 are connected to one side of each connecting block 715, and a top plate 702 is driven to one side of each connecting rod 716. Side plates 708 are slidably connected to the inner wall of each side groove 717. Two springs 712 are connected to one side of each side plate 708, with the other end of each spring 712 connected to one side of the inner wall of the side groove 717. A baffle 709 is connected to one side of each side plate 708, and the bottoms of both the baffle 709 and the side plate 708 are in contact with the top of the conveying module 1. The two connecting rods 716 are connected to the same... The support plate 701 has a trapezoidal groove 705 on one side, in which two trapezoidal blocks 704 are slidably connected. One side of the trapezoidal blocks 704 is connected to one side of the top plate 702. A top groove 706 is formed at the top of the trapezoidal groove 705, in which two fixing bolts 707 are slidably connected. Nuts are embedded at the top of the two trapezoidal blocks 704, and the nuts are threaded to the outer wall of the corresponding fixing bolts 707. A side groove 717 is formed on one side of the adjusting device 8, and two through holes 714 are formed on one side of the side groove 717. A support rod 710 is slidably connected to the inner wall of the through hole 714. One end of the support rod 710 is connected to one side of the side plate 708, and the other end of the support rod 710 is connected to a limit plate 711. A spring 712 is sleeved on the outside of the support rod 710. A connecting groove 713 is opened at the top of the side groove 717, and the connecting rod 703 extends out of the side groove 717 through the connecting groove 713. The two sides of the connecting rod 703 are respectively attached to and slidably connected to the inner wall of the connecting groove 713. A material rack 4 is connected to one side of the conveying module 1, and the material rack 4 is located between the two linear modules 3.

[0031] In a specific implementation, by setting up a leveling device 7, the electric push rod 5's suction cup picks up the polarizer, and then the linear module 3 drives the support plate 6 to move, causing the support plate 6 to move the electric push rod 5. The electric push rod 5 moves the polarizer and places it on top of the conveying module 1. Subsequently, the linear module 3 drives the support plate 6 to reset, and the conveying module 1 moves the polarizer so that one side of the polarizer contacts one side of the baffle 709. The baffles 709 on both sides block the polarizer, and the conveyor belt of the conveying module 1 continuously frictionally drives the polarizer to rotate around the first contact point, thereby leveling the polarizer. This prevents tilting from affecting the accuracy of the polarizer during inspection. Then, the electric push rod 5 picks up a new polarizer and moves it, causing the support plate 6 to move the support plate 701 through the connecting block 715 and the connecting rod 716. The support plate 701 moves the top plate 702, causing the top plate 702 to press against the connecting rod. 703 causes the connecting rod 703 to move to one side, which in turn causes the side plate 708 to move. The side plate 708 then causes the baffle 709 to move, allowing the baffle 709 to slide into the side groove 717. This causes the baffle 709 to lose its blocking effect on the polarizer, allowing the polarizer to move to the detection module 2 for detection. The movement of the side plate 708 compresses the spring 712, causing the spring 712 to generate a rebound force. This causes the connecting rod 703 to separate from the top plate 702, and the side plate 708 to reset due to the rebound force of the spring 712. This allows it to block and align the next polarizer. The detection device is equipped with a light source that emits light. When the light passes through the polarizer, bubbles or foreign objects inside the polarizer can cause refraction, reflection, or scattering of the light, thus changing the direction of light propagation. By detecting these changes in optical signals, the presence of bubbles or foreign objects can be determined. This technology is existing technology and does not require detailed description.

[0032] The adjusting device 8 includes a mounting plate 807. The top of the mounting plate 807 is connected to the bottom of the conveying module 1. A dual-axis motor 809 is fixedly mounted on the bottom of the mounting plate 807. Threaded rods 808 are connected to the output shafts on both sides of the dual-axis motor 809. A threaded cylinder 806 is threadedly connected to the outer wall of the threaded rod 808. A connecting block 805 is connected to one side of the outer wall of the threaded cylinder 806. A movable frame 801 is connected to the top of the connecting block 805. A sliding plate 802 is connected to one side of the movable frame 801. An adjusting block 804 is connected to one side of the sliding plate 802. A side groove 717 is opened on one side of the adjusting block 804. The bottom of the adjusting block 804 is in contact with the top of the conveying module 1. A guide slope is provided on one side of the adjusting block 804. Two sliding sleeve seats 810 are connected to the bottom of the mounting plate 807. The inner wall of the sliding sleeve seat 810 is slidably connected to the outer wall of the threaded cylinder 806. A support sleeve 803 is slidably connected to the outer wall of the sliding plate 802. The bottom of the support sleeve 803 is connected to the top of the conveying module 1.

[0033] In a specific implementation, an adjustment device 8 is provided, and the conveying shafts on both sides of the dual-axis motor 809 drive two threaded rods 808 to rotate coaxially. Since the outer threads of the two threaded rods 808 are opposite, they drive two threaded cylinders 806 to move towards each other. This causes the threaded cylinders 806 to move the connecting block 805, which in turn moves the moving frame 801. The moving frame 801 then moves the sliding plate 802, which in turn moves the adjustment block 804. This allows the distance between the two adjustment blocks 804 to be adjusted, enabling them to guide polarizers of different sizes within a given range, thus improving the applicability of the device. A support sleeve 803 supports the sliding plate 802, preventing one end of the sliding plate 802 from drooping and affecting the support effect.

[0034] Working Principle: In use, polarizing films are placed into the material rack 4. Then, based on the size of a batch of polarizing films, the dual-axis motor 809 drives the threaded rod 808 to rotate. The threaded rod 808 moves the threaded cylinder 806, which in turn moves the connecting block 805. The connecting plate, through the moving frame 801, moves the sliding plate 802, which in turn moves the adjusting block 804, ensuring the two adjusting blocks 804 guide the polarizing films. Then, the suction cup of the electric push rod 5 picks up the polarizing film. The linear module 3 then moves the support plate 6, which in turn moves the electric push rod 5, moving the polarizing film to its placement position. The polarizing film is then placed on top of the conveyor module 1. The linear module 3 then resets the support plate 6, causing the suction cup of the electric push rod 5 to pick up a new polarizing film. The conveyor belt of the conveyor module 1 moves the polarizing film until one side of the polarizing film contacts the side of the baffle 709, allowing the baffle 709 to polarize the film. The polarizer is blocked, causing it to align. The linear module then moves the support plate 6, which in turn moves the support plate 701 via the connecting plate and block 715. The support plate 701 then moves the top plate 702, which presses against the connecting rod 703. This causes the connecting rod 703 to move the side plate 708, which in turn moves the baffle 709 into the side groove 717. This removes the baffle 709's obstruction of the polarizer, and the polarizer then passes through the conveyor belt. The transmission allows the aligned polarizer to move. Once the polarizer moves out of the side of the baffle 709, the conveyor belt stops rotating, causing the electric push rod 5 to release the re-lifted polarizer. Finally, the linear module 3 drives the support plate 6 to reset again, causing the top plate 702 to separate from the connecting rod 703. The side plate 708 is then reset by the rebound of the spring 712, allowing the baffle 709 to block and align the subsequent polarizers. By aligning the polarizers, the accuracy of the polarizers during testing is ensured.
