Description

Roller jig

technical field

The invention relates to a roller fixture, in particular to a roller fixture used for nano transfer printing.

Background technique

The existing roller jig usually includes a solid roller and supporting shafts arranged at both ends of the roller. The roller jig is installed on a special roller processing machine through a support shaft for engraving. The roller jig after processing is installed on the rotating shaft of the transfer machine through the supporting shaft, so as to transfer the optical film under the drive of the rotating shaft.

The cylinder will generate heat due to high-intensity friction during the engraving process, so the cylinder needs to be cooled during the engraving process to avoid damage to the cylinder due to excessive temperature. However, a solid drum is inconvenient to arrange cooling liquid for cooling in the drum, thereby affecting the cooling efficiency of the drum.

Contents of the invention

In view of this, it is necessary to provide a roller jig that is easy to cool down and easy to process.

A roller jig includes a hollow roller body and a pair of rotating parts. The drum body includes an outer wall and a pair of end faces vertically connected to the outer wall. The rotating member includes a flange corresponding to the shape of the end face and a support shaft extending vertically outward from the middle part with the flange. The end surface and the flange can be screwed to each other through bolts, and cooling liquid is arranged in the drum body.

Compared with the prior art, the drum jig provided by the present invention can improve the cooling efficiency of the drum jig by providing cooling fluid in the hollow drum body, and avoid damage to the drum body caused by high temperature during engraving.

Detailed ways

As shown in FIGS. 1 and 2 , the roller jig 1 provided by the embodiment of the present invention includes a roller body 10 , a pair of connecting pieces 12 and a plurality of bolts 13 . The connectors 12 are detachably mounted on both ends of the drum body 10 via bolts 13 .

The drum body 10 is a hollow cylinder with two ends open, which includes a cylindrical outer wall 100 and a pair of end faces 102 vertically connected to the outer wall 100 . The end surface 102 is annular, and a plurality of threaded holes 102a evenly spaced are arranged on the periphery of the end surface 102 . The outer wall 100 is used for engraving and processing patterns with micro-nano structures. The pattern of the micro-nano structure can be various micro-structures with different optical functions. Using the micro-nano structure pattern, the roller body 10 can be used to continuously roll and transfer various optical films, such as: display backlight module film, anti-reflection film, laser hologram, electronic label or anti-counterfeiting Wafer etc. Cooling liquid can also be provided inside the cylinder body 10 to cool the cylinder body 10 during the engraving process so as to avoid overheating of the cylinder body 10 .

The connecting member 12 includes a flange 120 and a supporting shaft 122 . The flange 120 has a circular structure, and a plurality of evenly spaced screw holes 120a are provided on its periphery corresponding to the threaded holes 102a of the drum body 10 . The supporting shaft 122 is vertically extended from the middle of the flange 120 outwards. A connection block 124 extends axially from the end of the support shaft 122 away from the flange 120 . The connecting block 124 is a circular protrusion coaxially arranged with the supporting shaft 122 . The radius of the connecting block 124 is slightly smaller than that of the supporting shaft 122 . The connecting block 124 includes an outer surface 124a. The outer surface 124a is provided with a connecting thread 124b.

Please refer to FIG. 3 together. When processing the drum body 10 , the drum body 10 needs to be fixed on a precision machining machine 2 first. The precision machining machine 2 includes a vacuum suction head 20 and a cutter 22 . The vacuum suction head 20 includes an adsorption surface 20 a , and one end surface 102 of the roller body 10 is adsorbed and fixed on the adsorption surface 20 a of the vacuum suction head 20 . After the roller body 10 is fixed, the cutter 22 performs engraving on the outer wall 100 of the roller body 10 to form the micro-nano structure pattern.

Please also refer to FIG. 4 , when using the processed cylinder body 10 for transfer printing, the cylinder body 10 needs to be fixed on a transfer machine 3 first. The transfer machine 3 includes a pair of rotating shafts 30 disposed opposite to each other. One end of the rotating shaft 30 is provided with a threaded groove (not shown) corresponding to the connecting thread 124b on the connecting block 124 . In order to cooperate with the rotating shaft 30 to fix the drum body 10 on the rotating shaft 30, the screw holes 120a on the flange 120 are respectively aligned with the threaded holes 102a of the drum body 10, and pass through A plurality of bolts 13 respectively fix the connecting pieces 12 on the end surfaces 102 of the drum body 10 . The connecting block 124 at the end of the supporting shaft 122 is screwed into the threaded groove to fix the roller body 10 on the rotating shaft 30 of the transfer machine 3 . Therefore, the roller fixture 1 is driven by the rotating shaft 30 to roll, so as to transfer the micro-nano structure pattern on the roller body 10 to the flexible substrate 4 placed under the roller fixture 1 .

The drum jig 1 provided by the present invention can improve the cooling efficiency of the drum jig 1 by arranging cooling liquid in the hollow drum body 10 , and avoid damage to the drum body 10 caused by high temperature during engraving.
