[0026] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] In the liquid crystal panel polarizer coil equipment, the polarizer raw materials are loaded in rolls. In actual production, the polarizer coils stored in the warehouse are of various types. Generally, the specifications of the polarizer coil core drums are 6 inches and 12 inches. According to the different specifications of the polarizer coil core drums, the loading components of the liquid crystal panel polarizer coil equipment need to use core heads of different sizes to fix the polarizer coil to the rotating shaft of the liquid crystal panel polarizer coil equipment. In order to avoid replacing the core head and make a single core head meet the needs of two different specifications of polarizer coils, the present application provides the following composite coil inner core positioning head embodiment.

[0028] Please refer to Figure 1The present application provides an embodiment of a composite coil core positioning head. The composite coil core positioning head includes a connecting base 100, which secures the composite coil core positioning head to the polarizer coil rotating shaft. A first inner core insertion boss 200 and a second inner core insertion boss 300 are provided on the other side of the connecting base 100. The first inner core insertion boss 200 is disposed within the second inner core insertion boss 300, and the first inner core insertion boss 200 and the second inner core insertion boss 300 are coaxial. An inner core insertion groove 700 is provided between the first inner core insertion boss 200 and the second inner core insertion boss 300. The inner core insertion groove 700 provides space for inserting the core of a smaller coil. A first expansion ring 500 is sheathed on the outer wall of the first inner core insertion boss 200, and a second expansion ring 600 is sheathed on the outer wall of the second inner core insertion boss 300. The first expansion ring 500 and the second expansion ring 600 are both expandable silicone rings. The first expansion ring 500 expands so that a smaller-sized winding core can be inserted and connected tightly without loosening, and the second expansion ring 600 expands so that a larger-sized winding core can be inserted and connected tightly without loosening.

[0029] In this embodiment, the first inner core insertion boss 200 is adapted to be inserted into the core of a coil of one specification, while the second inner core insertion boss 300 is adapted to be inserted into the core of a coil of a larger specification. The expansion of the first and second expansion rings 500 and 600 secures the coils tightly and securely, preventing rotation or slippage, thereby ensuring proper loading of the polarizer coils. This complex structural design allows a single coil core positioning head to secure two coils of varying specifications. When loading two polarizer coils, continuous loading can be achieved without replacing the coil core positioning head. This not only shortens production time but also reduces operational complexity and safety risks for operators.

[0030] At the same time, this application also helps to optimize inventory management, and can reasonably predict and reserve commonly used coil models to reduce downtime caused by waiting for coils of specific specifications.

[0031] In one embodiment, the first inner core insertion boss 200 is suitable for insertion into a 6-inch winding core, and the second inner core insertion boss 300 is suitable for insertion into a 12-inch winding core. When the winding barrel of the polarizer film roll is inserted into the first inner core insertion boss 200 or the second inner core insertion boss 300, the first expansion ring 500 or the second expansion ring 600 expands, ensuring a tight connection between the winding barrel and the winding barrel, thus completing the winding process.

[0032] like Figure 2 and Figure 3As shown, in one embodiment, the bottom ends of the first inner core plug-in boss 200 and the second inner core plug-in boss 300 are connected to form an integrated structure by a connecting plate 800. The connecting base 100 is provided with a fixing groove, and the connecting plate 800 is embedded in the fixing groove. The integrated structure and fixing groove design simplify the connection of various components and facilitate the positioning of the first inner core plug-in boss 200 and the second inner core plug-in boss 300 during product assembly. At the same time, the simple connection method can also reduce the difficulty of operation during the production and assembly of the composite coil inner core positioning head product, and facilitate the inspection and assembly of the composite coil inner core positioning head.

[0033] like Figure 1 As shown, in one embodiment, a plurality of first connection holes 210 are provided on the first inner core plug boss 200, and a plurality of second connection holes 310 are provided on the second inner core plug boss 300. Blind holes are provided on the connecting plate 800 corresponding to the first connection holes 210. Bolts are inserted into the first connection holes 210 and the second connection holes 310 to connect the first inner core plug boss 200 and the second inner core plug boss 300 to the connecting plate 800. A third connection hole 810 is provided coaxially with the first connection hole 210 on the connecting plate 800. A blind hole is provided in the fixing groove corresponding to the third connection hole 810. Bolts are inserted into the third connection hole 810, and the connecting plate 800 is screwed to the connecting base 100. The present application uses a screw-fixed connection method to fix the first inner core plug boss 200 and the second inner core plug boss 300, which is a simple fixed connection method. At the same time, when fixing the composite coil core positioning head to the rotating shaft of the liquid crystal panel polarizer coil equipment, first fix the connecting base 100, and the first inner core plug-in boss 200 and the second inner core plug-in boss 300 can be finally assembled into the fixed groove of the connecting base 100 to facilitate the installation of the composite coil core positioning head.

[0034] like Figure 2 、 Figure 3 As shown, in this embodiment, the first inner core plug-in boss 200 and the second inner core plug-in boss 300 are respectively bolted to the connecting plate 800, and the connecting plate 800 is bolted in the fixing groove. The pneumatic connecting tube of the first expansion ring 500 passes through the first inner core plug-in boss 200 to be connected to the pneumatic source, and the pneumatic connecting tube of the second expansion ring 600 passes through the second inner core plug-in boss 300 to be connected to the pneumatic source.

[0035] like Figure 1 and Figure 2As shown, in one embodiment, the center of the first inner core plug-in boss 200 is hollow and a piston rod 400 is provided inside. An expansion linkage mechanism is provided on the wall of the fixed groove. After the piston rod 400 is inflated, it is pushed out and connected to the expansion linkage mechanism, and the first expansion ring 500 and / or the second expansion ring 600 expand. This application utilizes the pneumatic principle. After inflation, the piston rod 400 is pushed out and the piston rod 400 is pushed onto the expansion linkage mechanism and then expanded, thereby expanding the expansion silicone ring. After the winding core tube is inserted, it can be tightly connected without loosening, ensuring normal loading. Expansion is fixed, and the control method is simple and precise.

[0036] like Figure 1 As shown, in one embodiment, the number of first connection holes 210 and second connection holes 310 is the same, and they are all symmetrically distributed, with both centers of symmetry coinciding with the axis of the first inner core plug-in boss 200. A line connecting the axis of the first inner core plug-in boss 200 and the center of any first connection hole 210 passes through the center of the second connection hole 310 at the corresponding position, meaning that the first connection holes 210, the second connection holes 310, and the center of symmetry in the same direction are on a straight line. That is, the first connection holes 210 and the second connection holes 310 are radially and symmetrically arranged. This arrangement of the fixing holes allows for even distribution of the force applied by the screws during the fixing connection, ensuring balanced force when the composite coil core positioning head is inserted into the coil core drum, thereby ensuring balanced rotational loading of the polarizer coil.

[0037] like Figure 1 As shown, in one embodiment, there are six first connection holes 210 symmetrically distributed on the first inner core plug-in boss 200 ; there are six second connection holes 310 symmetrically distributed on the second inner core plug-in boss 300 .

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, a first groove is provided on the outer wall of the first inner core insertion boss 200, and a second groove is provided on the outer wall of the second inner core insertion boss 300. The inner ring of the first expansion ring 500 is embedded in the first groove, and the inner ring of the second expansion ring 600 is embedded in the second groove. The first groove and the second groove fix the socket position of the first expansion ring 500 and the second expansion ring 600, facilitate the rapid positioning of the first expansion ring 500 and the second expansion ring 600, and limit the movement of the first expansion ring 500 and the second expansion ring 600.

[0039] In one embodiment, top ends of the first inner core inserting boss 200 and the second inner core inserting boss 300 are flush with each other.
