As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6 As shown, the embodiment of the utility model provides an automated winding device for nano magnetic cores, including a work frame 1, electric turntables 4 are arranged on the left and right sides of the inner side of the work frame 1, and a winding frame 5 is arranged on the inner side of the two electric turntables 4. The left and right sides of the surface of the winding frame 5 are provided with plug holes 6, and a mounting plate 8 is fixedly installed on the left side of the inner side of the plug hole 6. The top of the plug hole 6 is threadedly connected with a lower pressing plate 7 by bolts, and the bottom of the lower pressing plate 7 is in contact with the top of the mounting plate 8;

[0031] The inner sides of the two electric turntables 4 are provided with mounting mechanisms 2, and the mounting mechanisms 2 include boxes 201 and moving blocks 205. The two boxes 201 are fixedly mounted on the inner sides of the two electric turntables 4. Moving blocks 205 are arranged in the inner cavities of the two boxes 201. Connecting rods 206 are fixedly mounted on the outer sides of the eight moving blocks 205. Fixed plates 207 are fixedly mounted on the inner sides of the eight connecting rods 206. Insertion blocks 208 are fixedly mounted on the inner sides of the eight fixing plates 207. The eight insertion blocks 208 are plugged into the inner cavities of the eight jacks 6. The outer sides of the inner cavities of the two boxes 201 are fixedly mounted with first motors 202. The output ends of the two first motors 202 are fixedly connected with Square plates 203, the outer sides of the two square plates 203 are movably connected with L-shaped rods 204, the inner sides of the eight L-shaped rods 204 are movably connected to the outer sides of the eight moving blocks 205 through rotating shafts, the outer sides of the inner cavities of the two boxes 201 are provided with moving grooves 209, the outer sides of the eight moving blocks 205 are slidably connected in the inner cavities of the eight moving grooves 209, the surfaces of the two boxes 201 are provided with slots 210, the eight connecting rods 206 penetrate the inner cavities of the eight slots 210 and extend to the outer sides of the two boxes 201, the eight sockets 6 and the eight plug blocks 208 are in the same horizontal direction, and the dimensions of the inner cavities of the eight sockets 6 match the dimensions of the eight plug blocks 208.

[0032] By setting up the installation mechanism 2, the square plate 203 is rotated through the output of the first motor 202, and the rotation of the square plate 203 drives the L-shaped rod 204 to flip. At this time, the moving block 205 moves outward due to the flipping of the L-shaped rod 204. As the moving block 205 moves, the connecting rod 206 synchronously drives the fixed plate 207 to move outward. As the fixed plate 207 moves, the plug block 208 is moved out of the inner cavity of the socket 6, completing the disassembly of the winding frame 5. The above-mentioned disassembly method is relatively convenient, and there is no need for the operator to disassemble the winding frame 5 by himself. Compared with the use of bolts for fixing, it can effectively reduce the steps of repeatedly tightening the bolts, thereby improving the operation of the winding frame 5. The speed of disassembly or installation reduces the waste of labor costs and is convenient for operators to use. By setting the moving groove 209, the movement of the moving block 205 can be limited to avoid the direction of the moving block 205 being offset when moving, thereby affecting the installation or disassembly of the winding frame 5. By setting the slot 210, the movement of the connecting rod 206 can be limited to avoid the change of the direction of movement of the connecting rod 206, which makes it impossible to disassemble or install the winding frame 5. By setting the socket 6 and the plug block 208, since the two are in the same horizontal direction and the sizes match each other, the plug block 208 can be firmly plugged into the inner cavity of the socket 6, which improves the stability of the winding frame 5 during installation.

[0036] When the utility model is working: when the surface of the winding frame 5 is fully wound with the magnetic core, the square plate 203 is first rotated by the output of the first motor 202, and the L-shaped rod 204 is turned over by the rotation of the square plate 203. At this time, the moving block 205 moves outward due to the turning of the L-shaped rod 204. With the movement of the moving block 205, the connecting rod 206 synchronously drives the fixed plate 207 to move outward. With the movement of the fixed plate 207, the plug block 208 moves out of the inner cavity of the socket 6. , the disassembly of the winding rack 5 is completed, and then the new winding rack 5 is placed on the inner side of the box body 201, and then the square plate 203 is rotated in the opposite direction through the output of the first motor 202. At this time, the L-shaped rod 204 is flipped inward due to the rotation of the square plate 203, and the moving block 205, the connecting rod 206 and the fixed plate 207 are pulled to move synchronously. At this time, with the movement of the fixed plate 207, the plug block 208 is plugged into the inner cavity of the winding rack 5 again, thereby completing the installation of the winding rack 5.
