Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polarizing film roll core fixing, in particular to a fixing mechanism suitable for 3-inch and 6-inch polarizing film roll cores. Background Art
[0002] Polarizer is the full name of polarizing film, which can control the polarization direction of a specific light beam. When natural light passes through the polarizer, the light whose vibration direction is perpendicular to the transmission axis of the polarizer will be absorbed, and only the polarized light whose vibration direction is parallel to the transmission axis of the polarizer will be transmitted. There are two polarizers in the liquid crystal display module, which are attached to both sides of the glass substrate. The lower polarizer is used to convert the light beam generated by the backlight source into polarized light, and the upper polarizer is used to analyze the polarized light after the liquid crystal is electrically modulated to produce light and dark contrast, thereby producing a display picture. The imaging of the liquid crystal display module must rely on polarized light. Without any polarizer, the liquid crystal display module cannot display an image. In order to realize the automated assembly line production of liquid crystal panels (RTP) to reduce production costs and increase production speed, the production line uses polarizer rolls to directly attach to the liquid crystal glass plate.
[0003] At present, in the prior art, for the polarizing film core, a device of a specific size is often required to fix it so as to rotate the core and complete the production line process. However, this type of fixing device can only be adapted to a core of one size and cannot be applied to cores of multiple sizes, especially small-sized cores. Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Reference Figure 1 and Figure 2A fixing mechanism suitable for 3-inch and 6-inch polarizing film roll cores, comprising a connecting seat 1, an inflatable seat 2 is installed on one side of the connecting seat 1, an air path 3 is connected to the inflatable seat 2, and an air valve 4 is arranged on the air path 3, a piston 5 is arranged inside the inflatable seat 2, a connecting column 6 is installed at the center of the piston 5 away from the connecting seat 1, springs 7 are arranged on both sides of the connecting column 6, and one end of the two springs 7 is connected to the piston 5, and the other end is connected to the inner wall of the inflatable seat 2, a first mounting seat 8 is installed on the side of the inflatable seat 2 away from the connecting seat 1, and a second mounting seat 9 is installed on the other side of the first mounting seat 8, and the outer diameter of the second mounting seat 9 is smaller than that of the first mounting seat 8. The outer diameter of the mounting seat 8, the end of the connecting column 6 away from the piston 5 is sequentially provided with a truncated cone member 10 and a conical member 16, the outer diameter of the conical member 16 is smaller than the outer diameter of the truncated cone member 10, the truncated cone member 10 and the conical member 16 are respectively located in the first mounting seat 8 and the second mounting seat 9, the inner diameter size of the second mounting seat 9 is adapted to the outer diameter of the conical member 16, the outer sides of the first mounting seat 8 and the second mounting seat 9 are both provided with expansion rings 11 adapted thereto, the inner side of the expansion ring 11 is provided with a slider 12 assembly, the two slider 12 assemblies are respectively movable through the first mounting seat 8 and the second mounting seat 9, and respectively abut against the outer sides of the hypotenuse parts of the truncated cone member 10 and the conical member 16.
[0019] When the device is in use, for example, the device is suitable for 6-inch winding cores and 3-inch winding cores (determined by the size of the first mounting seat 8 and the second mounting seat 9). After the winding core is placed in one of the expansion rings 11, the air valve 4 is opened, and the cavity of the inflatable seat 2 is inflated using an external inflating device. The gas enters the cavity, and the air pressure is used to push the piston 5 to move axially, so that the truncated table 10 and the conical part 16 drive the slider 12 to move radially, pushing the corresponding expansion ring 11 to expand outward, and finally the expansion ring 11 tightly supports the winding core. Since the conical part 16 has a tip that the truncated table 10 does not have, the tip can be used to apply force to the corresponding slider 12. Therefore, The second mounting seat 9 can be designed to be smaller in size to meet the need of the prior art that is lacking in the ability to fix cores of different sizes and smaller sizes. The core can be rotated by connecting the connecting seat 1 through an external power device. After the operation is completed, the external air circuit is closed, the air valve 4 is opened to exhaust the gas, the piston 5 is reset by the elastic force of the spring 7, and the expansion ring 11 shrinks back to its original position. Compared with the prior art, the present device utilizes a frustum and a conical part 16 to fix cores of different sizes, and the conical part 16 can be suitable for cores of smaller sizes, which solves the problem that the prior art can only be adapted to cores of one size and cannot be adapted to cores of multiple sizes, especially small-sized cores.
[0020] In this embodiment, a connecting plate 18 is installed on the side of the second mounting seat 9 close to the first mounting seat 8. The connecting plate 18 is detachably connected to the first mounting seat 8 by bolts. The second mounting seat 9 can be installed on the first mounting seat 8 through the connecting plate 18, which makes it convenient to disassemble the second mounting seat 9 and replace the second mounting seat 9 (maintain or replace the second mounting seat 9 of different sizes).
[0021] In this embodiment, the inflatable seat 2 includes a left outer shell 14 and a right outer shell 15, and the left outer shell 14 and the right outer shell 15 are detachably connected by bolts, and the left outer shell 14 and the right outer shell 15 are provided with sealing gaskets, which are convenient for separating the left outer shell 14 and the right outer shell 15, and inspecting and maintaining the piston 5 and the spring 7 to prevent the piston 5 from being insufficiently airtight due to long-term use, resulting in the piston 5 being unable to move normally, resulting in the inability to push the connecting column 6 to move, and the spring 7 being unable to reset the piston 5 due to long-term use.
[0022] In this embodiment, the slider assembly includes a plurality of sliders 12, and the outer sides of the hypotenuse parts of the truncated table member 10 and the conical member 16 are both against the inner ends of the corresponding sliders 12. The sliders 12 are T-shaped as a whole, and the outer ends of the sliders 12 are arc-shaped. When the truncated table member 10 or the conical member 16 moves horizontally, the sliders 12 can exert force on multiple positions on the inner side of the expansion ring 11, thereby fixing the inner side of the winding core and improving the stability of the winding core fixation.
[0023] In this embodiment, the material of the expansion ring 11 is polyurethane, and limiting grooves 13 are provided at the positions of the first mounting seat 8 and the second mounting seat 9 corresponding to the corresponding expansion ring 11. The outer side of the expansion ring 11 is flush with the outer side of the limiting groove 13, which is convenient for limiting the position of the expansion ring 11 and preventing the expansion ring 11 from detaching from the corresponding mounting seat.
[0024] In this embodiment, a threaded rod 17 is installed on the side of the truncated cone member 10 away from the connecting column 6, and the conical member 16 is sleeved on the outside of the threaded rod 17 and is connected to the threaded rod 17 by threads. The conical member 16 can be disassembled and assembled through the threaded rod 17, so that the conical member 16 can be replaced and is suitable for second mounting seats 9 of different sizes.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
