[0026] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0027] See also Figure 1 and Figure 2 The present invention provides a conveying and separating mechanism 100, which can separate products to be transported during the conveying process to ensure that the products to be transported can effectively enter the next process in a separated state. The conveying and separating mechanism 100 includes a cutting mechanism 1, a conveying mechanism 2 and a separating mechanism 3, wherein the cutting mechanism 1, the conveying mechanism 2 and the separating mechanism 3 are arranged in the same direction, and optionally, the cutting mechanism 1 and the conveying mechanism 2 are arranged on both sides of the separating mechanism 3.

[0028] The cutting mechanism 1 is used as the first process of the conveying and separating mechanism 100 to cut the polarizer, wherein the polarizer can be a roll, and the polarizer in the roll state is sequentially introduced into the cutting mechanism 1, and the cutting mechanism 1 cuts the polarizer in the roll state sequentially through a cutting knife to form a plurality of polarizers in the form of sheets, and the plurality of polarizers in the form of sheets are sequentially transferred from the cutting mechanism 1 to the conveying mechanism 2.

[0029] The conveying mechanism 2 is the third process of the conveying and separating mechanism 100 , and is disposed at one side of the cutting mechanism 1 and docked with the cutting mechanism 1 ; the conveying mechanism 2 is used to convey the polarizer to transfer the polarizer to the next process.

[0030] The conveying mechanism 2 may be a conveyor belt driven by a driving mechanism, and the conveyor belt may be annular. The conveyor belt rotates cyclically under the drive of the driving mechanism, and drives the movement of the polarizer through the friction between the conveyor belt and the polarizer.

[0031] See also Figure 1 and Figure 2, as the second process of the conveying and separating mechanism 100, the separating mechanism 3 is arranged between the cutting mechanism 1 and the conveying mechanism 2 and is used to separate adjacent polarizers. Among them, the polarizers cut by the cutting mechanism 1 are close to each other and move at the same speed.

[0032] Adjacent polarizers are separated by the separating mechanism 3, so that adjacent polarizers are spaced apart from each other, facilitating the transfer of the polarizers to the next process driven by the conveying mechanism 2, and avoiding the front-to-back adhesion of multiple polarizers on the transition section between the cutting mechanism 1 and the conveying mechanism 2, thereby realizing the entry of polarizers into the next process one by one.

[0033] The separating mechanism 3 includes a first separating section 31, a second separating section 32 and a third separating section 33. The first separating section 31 and the second separating section 32 are arranged adjacent to each other, and the first separating section 31 and the third separating section 33 are arranged on both sides of the second separating section 32 respectively, so as to realize multiple separations of the polarizers under the action of the first separating section 31, the second separating section 32 and the third separating section 33, ensure the separation effectiveness of the polarizers, and avoid the connection of polarizers.

[0034] In addition, the first separating section 31 is arranged relative to the cutting mechanism 1, the third separating section 33 is arranged relative to the conveying mechanism 2 and is arranged opposite to the first separating section 31, maintaining the same height, ensuring the transfer efficiency of the polarizers, and the second separating section 32 is arranged from the cutting mechanism 1 towards the conveying mechanism 2 and is located below the third separating section 33 and the first separating section 31 to maintain the transfer of the polarizers from the cutting mechanism 1 to the conveying mechanism 2 in the horizontal direction, avoiding the bending of the polarizers during the movement and ensuring the surface quality of the polarizers.

[0035] Among them, there is a speed difference between the second separating section 32 and the first separating section 31, so the moving speeds of the polarizers on the second separating section 32 and the first separating section 31 are different, enabling multiple adjacent polarizers in the front and back to move under the drive of different speeds, so that the moving speeds of multiple adjacent polarizers in the front and back are different, ensuring the separation of multiple polarizers and not affecting the transfer of the polarizers from the cutting mechanism 1 to the conveying mechanism 2, and ensuring the working efficiency of the conveying and separating mechanism 100.

[0036] Moreover, it is convenient for the polarizers to be separated during the process from the cutting mechanism 1 to the conveying mechanism 2, thereby improving the separation efficiency of the polarizers and avoiding the front-to-back adhesion of multiple polarizers on the transition section between the cutting mechanism 1 and the conveying mechanism 2.

[0037] A plurality of first rollers 311 are provided on the first separating section 31. The plurality of first rollers 311 are sequentially installed on the same drive shaft and are arranged at intervals along the drive shaft.

[0038] The first roller 311 rotates driven by the drive shaft and can contact the surface of the polarizer to drive the polarizer to move forward.

[0039] A plurality of second rollers 321 are provided on the second separation section 32. The plurality of second rollers 321 are sequentially installed on the same drive shaft and are arranged at intervals along the drive shaft.

[0040] The second roller 321 rotates driven by the drive shaft and can contact the surface of the polarizer to drive the polarizer to move forward. Among them, the diameter of the second roller 321 is smaller than that of the first roller 311, so as to form a speed difference between the second separation section 32 and the first separation section 31. Moreover, the second roller 321 and the first roller 311 can be controlled by different drive sources to achieve differential speed adjustment. Therefore, there is a speed difference between the second separation section 32 and the first separation section 31. By adjusting the moving speed of adjacent polarizers through the speed difference between the second separation section 32 and the first separation section 31, it is convenient for the polarizer to be separated during the process from the cutting mechanism 1 to the conveying mechanism 2, thereby improving the separation efficiency of the polarizer and avoiding the front-to-back adhesion of multiple polarizers on the transition section between the cutting mechanism 1 and the conveying mechanism 2.

[0041] Specifically, the diameter of the second roller 321 is 40 mm, and the diameter of the first roller 311 is 60 mm. The first separation section 31 and the second separation section 32 are independent of each other.

[0042] The second roller 321 is arranged in a staggered manner with the corresponding first roller 311 in its axial direction, so that the polarizer is affected by the second roller 321 and the first roller 311 at multiple positions, ensuring the stability of the polarizer during movement, and being conducive to the arrangement of the second roller 321 and the first roller 311, reducing the occupied space of the separation mechanism 3. At the same time, the speeds and positions of the second roller 321 and the first roller 311 are different, achieving separation in the front, back, left, and right four directions.

[0043] The third separation section 33 and the first separation section 31 are arranged on both sides of the second separation section 32; there is a speed difference between the speed of the third separation section 33 and that of the second separation section 32, and there is also a speed difference between the second separation section 32 and the first separation section 31. Therefore, the polarizer has multiple separations in the separation mechanism 3, and the moving efficiency of the polarizer is ensured during the separation process, ensuring the separation of the polarizer.

[0044] Among them, the speed of the third separation section 33 is the same as that of the first separation section 31, both being greater than the speed of the second separation section 32. A third roller 331 is provided on the third separation section 33. The diameter of the third roller 331 is larger than that of the second roller 321 and is equal to the diameter of the first roller 311.

[0045] The third roller 331 is arranged in an offset manner in its axial direction with respect to the corresponding second roller 321 and the first roller 311 in sequence, so that the polarizer is acted upon by the second roller 321, the first roller 311 or the third roller 331 at multiple positions, ensuring the stability of the polarizer during movement, and facilitating the arrangement of the second roller 321, the first roller 311 or the third roller 331, reducing the occupied space of the separating mechanism 3. At the same time, the third roller 331, the second roller 321 and the first roller 311 have different speeds and positions, realizing separation in the front, back, left and right directions.

[0047] Mount the polarizer of the coil stock on the cutting mechanism 1, and the cutting mechanism 1 cuts it to form a plurality of the polarizers;

[0048] A plurality of the polarizers are transferred from the cutting mechanism 1 to the first separation section 31 of the separating mechanism 3;
