Specifically, as shown in fig. 1: the first milling cutter 4 'has a first cylindrical cutter handle 41', the first cutter handle 41 'has a lower end formed with a first cutting edge 42' which makes the cutting edge face the first cutter handle 41 'with a right-handed screw, the upper processing shaft 2' clamps the first cutter handle 41 'and rotates clockwise on a horizontal plane which faces upwards in the normal direction, so that the first cutting edge 42' performs forward milling processing on the left edge of the polarizer 1 'and discharges chips towards the first cutter handle 41'; the second milling cutter 5 'has a cylindrical second cutter holder 51', the second cutter holder 51 'has a lower end formed with a second blade 52' for making the cutting edge face the second cutter holder 51 'with a right-hand spiral, and the lower processing shaft 3' clamps the second cutter holder 51 'and rotates counterclockwise on a horizontal plane facing downward in the normal direction, so that the second blade 52' performs the forward milling processing on the right edge of the polarizer 1 'and discharges chips toward the second cutter holder 51'.

In practice, the applicant has found that in the biaxial processing structure shown in fig. 1, although the direction of rotation of the first milling cutter 4 'relative to the second milling cutter 5' is the same, the direction of chip removal of the first milling cutter 4 'relative to the second milling cutter 5' is opposite, so that glue overflow and edge delamination can be caused when processing polarizers of soft glue and low glue viscosity, and color difference can also be caused on the end face of the polarizer at the processing side, which makes it difficult to meet the quality requirement.

Detailed Description

As shown in fig. 4 to 6, the biaxial processing structure for the trimming process of the polarizer has a jig 2 for horizontally holding a stack of polarizers 1, an upper processing shaft 3 and a lower processing shaft 4 arranged at opposite sides of the jig 2, the upper processing shaft 3 being loaded with a first milling cutter 5 protruding downward, the lower processing shaft 4 being loaded with a second milling cutter 6 protruding upward; the first milling cutter 5 is provided with a columnar first cutter handle 51, the first cutter handle 51 is provided with a first cutting edge 52 which enables a cutting edge to face the first cutter handle 51 in a right-handed spiral mode at the lower end, and the upper processing shaft 3 clamps the first milling cutter 5 to rotate clockwise so that the first cutting edge 52 is matched with the left side of the polarizer 1 in a right-handed clockwise milling mode and discharges chips towards the first cutter handle 51; the second milling cutter 6 is provided with a columnar second cutter handle 61, a second cutting edge 62 enabling a cutting edge to spirally face away from the second cutter handle 61 with a right hand is formed at the upper end of the second cutter handle 61, and the lower machining shaft 4 clamps the second milling cutter 6 to rotate anticlockwise so that the second cutting edge 62 is matched with the right side of the polarizer 1 in a right-hand left-hand cutting reverse milling mode and faces away from the second cutter handle 61 for chip removal.

In the above embodiment, the first milling cutter 5 has the same rotational direction and chip discharging direction with respect to the second milling cutter 6, in view of the fact that the first milling cutter 5 protrudes downward on the upper processing shaft 3, the second milling cutter 6 protrudes upward on the lower processing shaft 4, and the first milling cutter 5 rotates clockwise on a horizontal plane facing upward in the normal direction to cause the first cutting edge 52 to perform forward milling with right-handed right cutting, and the second milling cutter 6 rotates counterclockwise on a horizontal plane facing downward in the normal direction to cause the second cutting edge 62 to perform backward milling with right-handed left cutting. Because the first milling cutter 5 and the second milling cutter 6 have the same rotation direction and chip removal direction in the double-shaft processing structure, the problem that the left end face and the right end face have chromatic aberration is avoided, overflow glue and edge layering are not easy to generate for polaroids with low viscosity of soft glue and glue, and the obtained processing quality yield is greatly improved.
