DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a flattening device for producing an optical film provided by the utility model; Figure 2 for Figure 1 A rear view schematic diagram of a flattening device for producing an optical film is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 1 The enlarged schematic diagram of part B is shown. A flattening device for producing optical films comprises: a bottom plate 1, a motor mounting frame 2 is fixedly connected to the top of the bottom plate 1, a motor 3 is installed on the motor mounting frame 2, an active rod 4 is fixedly connected to the driving end of the motor 3, a first active disk 5 is fixedly connected to the active rod 4, a second active disk 6 is fixedly connected to the active rod 4, a belt 7 is connected to the surface of the first active disk 5 and the second active disk 6, two guide plates 8 are fixedly connected to the top of the bottom plate 1, guide grooves 9 are provided on the two guide plates 8, a downward pressing groove 10 is provided on the guide plates 8, and the top of the guide plates 8 is slidably connected to the guide plates 8. A guide slider 11 is connected to the guide slider 11, and a first connecting block 12 is fixedly connected to the bottom of the first connecting block 12. A moving block 15 is slidably connected to the surface of the moving block 15. An adaption groove 16 is provided on the moving block 15. A spring 17 is fixedly connected inside the adaption groove 16. An adaption rod 18 is fixedly connected to the other end of the spring 17. A flattening roller 19 is rotatably connected to the adaption rod 18. The flattening device does not require positioning and placing the optical film, which reduces the operation time and is simple and convenient. It can adapt to optical films of various areas, while enhancing the versatility of the device.
[0021] A dust removal box 20 is installed on the top of the base plate 1, and a wiping hard cloth 21 is fixedly connected inside the dust removal box 20. An electrostatic ring 22 is fixedly connected to the dust removal box 20. A collecting bin 23 is installed on the left side of the base plate 1, and a processing handle 24 is fixedly connected to the collecting bin 23. When the optical film passes through the dust removal groove of the dust removal box 20, the wiping hard cloth 21 wipes off the dust. After the electrostatic ring 22 is energized, a high-voltage electric field is established inside to generate static electricity, which absorbs the fallen dust. After the optical film completely passes through the dust removal box 20, the electrostatic ring 22 is de-energized, and the dust falls into the collection bin 23.
[0022] A connecting rod 13 is fixedly connected between the two first connecting blocks 12 , the moving block 15 is slidably connected to the lower pressing groove 10 , and the moving block 15 is slidably connected to the guide groove 9 . The connecting rod 13 can further ensure the consistency of the movement trajectories of the two moving blocks 15 .
[0023] The belt 7 is fixedly connected with a second connecting block 25, which is slidably connected to the guide plate 8. The second connecting block 25 is fixedly connected with a detection rod 26. After the flattening roller 19 is reset for the second flattening, the detection rod 26 can detect whether the optical film is flattened properly. If it is not qualified, it needs to be flattened again.
[0024] A transmission disk 27 is fixedly connected to the top of the base plate 1, and the transmission disk 27 is transmission-connected to the first active disk 5 via a belt 7. An electric heating plate 28 is installed on the top of the base plate 1, and a base 30 is fixedly connected to the bottom of the base plate 1. The electric heating plate 28 can increase the temperature of the optical film to achieve a better flattening effect.
[0025] A placement slot 29 is provided on the top of the bottom plate 1 , and a controller 31 is installed on the right side of the top of the bottom plate 1 . The controller 31 controls the start and stop of the motor 3 and the energization of the electrostatic ring 22 .
[0026] The working principle of the flattening device for producing optical films provided by the utility model is as follows:
[0027] After placing the optical film on the base plate 1, there is no need to deliberately adjust the position. Start the motor 3 to drive the active rod 4 to rotate, which in turn drives the two active disks to rotate, and then the belt 7 starts to move. The belt 7 drives the first connecting block 12 to move, and then the guide slider 11 slides on the guide plate 8. Since the telescopic rod 14 is inserted into the moving block 15, the moving block 15 starts to slide inside the lower pressure groove 10, and then slides into the guide groove 9. Since the position of the lower pressure groove 10 is higher than the guide groove 9, the moving block 15 moves downward, and the spring 17 is compressed to provide a certain pressure for flattening. The adaptation rod 18 retracts into the adaptation groove 16, and the flattening roller 19 rolls on the optical film to flatten it. The device can complete the flattening work without positioning the optical film, and can adapt to more optical films of different areas. It is simple and fast.
[0028] Compared with the related art, the flattening device for producing optical films provided by the utility model has the following beneficial effects:
[0029] The flattening device does not require positioning and placing the optical film, which reduces operation time and is simple and convenient. It can adapt to optical films of various areas, enhances the versatility of the device, and can also achieve efficient production. It also saves manpower and material resources required for positioning, reduces production costs, and can effectively handle surface dust to ensure the stable performance and quality of the optical film after flattening.
