When the wire is wound around the winding column 5, the electric telescopic rod 4 is used to move the connecting rod 3 and the connecting disk 14, so that the connecting disk 14 is separated from one end of the winding column 5. At this time, the fixing mechanism is unlocked to directly remove the formed spring contact from the winding column 5, which is convenient for operation. The equipment has a simple structure, small size, and low investment cost, and is suitable for small enterprises.

[0029] Furthermore, a through hole is opened on the surface of the vertical plate 2, and the through hole and the circular hole of the connecting plate 14 are concentric, and a chuck 6 for fixing the winding column 5 is fixedly installed on the side wall of the vertical plate 2 relative to the position of the through hole. The winding column 5 is fixed by the chuck 6, so the winding column 5 of different sizes can be replaced according to the diameter required to be wound.

[0030] Furthermore, a vertical groove is provided on the side wall of the connecting disk 14, and a slider 17 is slidably connected inside the vertical groove. A screw rod 18 is rotatably connected to the surface of the connecting disk 14. The screw rod 18 threadably passes through the slider 17, and a turning handle is fixedly installed on the end of the screw rod 18. The lever 13 is fixedly installed on the surface of the slider 17. In order to facilitate adaptation to winding columns 5 of different sizes and wires of different diameters, the distance between the lever 13 and the winding column 5 needs to be adjusted. At this time, it is only necessary to turn the turning handle, which drives the screw rod 18 to rotate, and the screw rod 18 drives the slider 17 to move in the vertical groove, so that the lever 13 moves synchronously, thereby achieving the purpose of changing the distance between the lever 13 and the winding column 5.

[0031] Furthermore, the driving mechanism includes a motor 16, which is fixedly mounted on the side wall of the connecting rod 3. A gear 15 is fixedly mounted on the output shaft port of the motor 16. Teeth are evenly arranged on the circumferential surface of the connecting disk 14. The gear 15 meshes with the connecting disk 14 through the teeth. When the driving mechanism is in use, the motor 16 is started, the motor 16 drives the gear 15 to rotate, the gear 15 drives the connecting disk 14 to rotate, and the connecting disk 14 drives the lever 13 to rotate around the winding column 5, so that the lever 13 drives the wire to be wound around the winding column 5.

When the fixing mechanism is in use, one end of the wire is placed between the first fixing rod 8 and the second fixing rod 9, and then the handle is manually rotated, and the handle drives the screw 12 to rotate. When the screw 12 rotates, it will move with the second fixing rod 9, thereby driving the extrusion rod 10 to move synchronously, and the extrusion rod 10 will not rotate due to the restriction of the limiting rod 11, so that the extrusion rod 10 and the first fixing rod 8 extrude and fix the wire.

[0033] Furthermore, a round block is provided at one end of the lever 13 away from the slider 17, and the diameter of the round block is larger than the lever 13. By providing the round block on the lever 13, when the lever 13 drives the wire to be wound, the round block can be used to drive the wire to move along the length direction of the winding column 5, thereby avoiding the wire from being wound at the same position.

[0034] In summary, during use, first select a suitable winding column 5 according to needs and install it on the vertical plate 2, and make the winding column 5 pass through the circular hole on the surface of the connecting disk 14. At this time, fix one end of the wire with a fixing mechanism, and then use the electric telescopic rod 4 to move the connecting rod 3 toward the vertical plate 2, use the driving mechanism to drive the connecting disk 14 to rotate, and use the lever 13 on the surface of the connecting disk 14 to move the wire, so that the other end of the wire is wound around the winding column 5. During the winding process, the electric telescopic rod 4 is also used to move the entire connecting rod 3, so that the lever 13 moves in a direction away from the fixing mechanism, so that the wire is evenly wound around the winding column 5 to form a spring shape. After the wire processing is completed, the electric telescopic rod 4 drives the connecting rod 3 and the connecting disk 14 to move, so that the connecting disk 14 is separated from one end of the winding column 5. At this time, the fixing mechanism is unlocked to directly remove the formed spring contact from the winding column 5, which is convenient for operation. The equipment has a simple structure, small size, low investment cost, and is suitable for small enterprises. The winding column 5 is fixed by the chuck 6, so the winding columns 5 of different sizes can be replaced according to the diameter of the winding required. In order to adapt to the winding columns 5 of different sizes and to the wires of different diameters, the distance between the lever 13 and the winding column 5 needs to be adjusted. At this time, you only need to turn the handle to drive the handle to The screw rod 18 rotates, and the screw rod 18 drives the slider 17 to move in the vertical groove, so that the lever 13 moves synchronously, and then the distance between the lever 13 and the winding column 5 can be changed. When the driving mechanism is in use, the motor 16 is started, the motor 16 drives the gear 15 to rotate, the gear 15 drives the connecting plate 14 to rotate, and the connecting plate 14 drives the lever 13 to rotate around the winding column 5, so that the lever 13 drives the wire to wind around the winding column 5. When the fixing mechanism is in use, one end of the wire is placed between the first fixing rod 8 and the second fixing rod 9, and then the handle is manually turned, and the handle drives the screw rod 12 to rotate. When the screw 12 rotates, it will send the second fixing rod 9 The extrusion rod 10 is restricted by the restriction rod 11 and will not rotate, so that the extrusion rod 10 and the first fixing rod 8 can extrude and fix the wire. By arranging a round block on the lever 13, when the lever 13 drives the wire to be wound, the round block can be used to drive the wire to move along the length direction of the winding column 5, so as to avoid the wire being wound at the same position. The pitch size of the spring contact body 19 is jointly determined by the extension speed of the electric telescopic rod 4 and the rotation speed of the motor 16. The control of the motor 16 and the electric telescopic rod 4 is controlled by the external controller and the program set in advance by the single-chip microcomputer, which is convenient for use.
