Description

Technical Field

[0002] Common-mode inductors, also called common-mode chokes, are often used in computer switching power supplies to filter common-mode electromagnetic interference signals. In board design, common-mode inductors also act as EMI filters to suppress the outward radiation of electromagnetic waves generated by high-speed signal lines. In order to save space on the core, multiple strands of wire are usually wound around the outside of the core. In order to reduce the skin effect of high-frequency inductors that causes coil overheating, multiple strands of enameled wire are usually insulated from each other to reduce the skin effect.

[0003] When an existing winding machine is in use, a robotic arm is usually used to move and bend the insulated wire so that the insulated wire is wound around the outside of the mold core. Different joints are provided at the end of the robotic arm to move the insulated wire. However, in the prior art, when the insulated wire of each group of mold cores is wound, the insulated wire is cut off by a cutting structure. When the insulated wire is cut off, a sharp cutting edge will remain on the cross section of the internal material (copper wire) of the enameled wire after the cut. During the winding process of the enameled wire, the robotic arm will pull the insulated wire to repeatedly wind it around the outside of the mold core. During the winding process, the enameled wire port will cause abrasion to the mold core and the already wound insulated wire. Summary of the invention

[0023] Step 2: Start the loading tray, the first motor drives the loading tray to rotate, so that the copper wire is sent out from the loading tray, and then start the second motor, the second motor drives the calibration wheel to rotate, straightens the copper wire, and transports the copper wire at the same time, so that the copper wire passes through the discharge groove and enters the guide groove in the guide plate. The copper wire is continuously transported, passes through the inner ring of the magnetic core, and reaches the inside of the limit plate;

[0024] Step 3: Start the cutting cylinder, which drives the cutting knife to cut the copper wire. Then start the moving cylinder to drive the hoisting frame and the adjustment cylinder to move downward synchronously, thereby driving the guide plate to move downward, so that the bottom end of the guide plate is inserted into the core, thereby limiting the position of the copper wire.

[0029] 1. The present invention can guide the copper wire when feeding it by providing a guide plate to prevent the copper wire from bending and being unable to enter the inner side of the magnetic core. After the copper wire is transported to a sufficient length, the copper wire can be cut off by a cutting device, and then the copper wire is guided by the guide plate so that the copper wire is always located at the edge of the inner ring of the magnetic core, thereby facilitating the copper wire to be wound around the outer side of the magnetic core.

[0030] 2. The present invention provides a guide plate and a movable cylinder, and when the copper wire is bent, the guide plate can be pushed downward by the movable cylinder to insert the guide plate into the inner side of the magnetic core, and then the circular arc chamfer on the side of the guide plate is driven by the adjusting cylinder to fit with the inner side of the magnetic core to release the limit on the copper wire. Subsequently, during the winding process of the copper wire, the guide plate can always cover the copper wire. During the winding process of the copper wire, the end of the copper wire rubs on the guide plate, thereby avoiding the wear of the end of the copper wire on the magnetic core and the rest of the copper wire, thereby improving the installation quality.

9. A winding process for a multi-strand insulated wire inductor, characterized in that The process of using the winding machine of the multi-strand insulated wire inductor according to any one of claims 1 to 8 comprises the following steps: Step 1: Place each group of magnetic cores into the magnetic core loading barrel, and transport the magnetic cores so that the magnetic cores pass through the pipeline to the bottom of the loading guide rail, and transport the magnetic cores to between multiple groups of clamping wheels through the loading guide rail, and push the clamping wheels to limit and fix the magnetic cores through the movable clamping rod; Step 2: Start the loading tray, the first motor drives the loading tray to rotate, so that the copper wire is sent out from the loading tray, and then start the second motor, the second motor drives the calibration wheel to rotate, straightens the copper wire, and transports the copper wire at the same time, so that the copper wire passes through the discharge groove and enters the guide groove in the guide plate. The copper wire is continuously transported, passes through the inner ring of the magnetic core, and reaches the inside of the limit plate; Step 3: Start the cutting cylinder, which drives the cutting knife to cut the copper wire. Then start the moving cylinder to drive the hoisting frame and the adjustment cylinder to move downward synchronously, thereby driving the guide plate to move downward, so that the bottom end of the guide plate is inserted into the core, thereby limiting the position of the copper wire. Step 4: Start the pulling feeding mechanism, the third motor drives the turntable to rotate, the turntable drives the fixed frame to move obliquely downward with the turntable, and moves the pulling wheel to the bottom of the magnetic core, and at the same time start the fourth motor, the fourth motor drives the pulling wheel to rotate to a vertical position, when the pulling wheel moves to one side of the copper wire, start the fourth motor to drive the pulling wheel to rotate to a horizontal position, the card slot of the pulling wheel is aligned with the copper wire, and then start the third motor in the reverse direction, the third motor drives the turntable to rotate, thereby driving the fixed frame to rotate obliquely upward, the pulling wheel pulls the copper wire to bend, and pushes the copper wire to rotate upward until the copper wire is wrapped around the outside of the magnetic core; Step 5: Adjust the cylinder to drive the guide plate to move horizontally on the inner ring of the magnetic core, so that the arc chamfer of the guide plate fits the magnetic core, the guide plate is separated from the copper wire, and the pull wheel pushes the copper wire to continue bending; Step 6: The pushing structure in the processing base will push the pull rod to move upward, the pull rod passes through the inside of the magnetic core and moves to the copper wire position, the pull rod continues to push upward, at this time, the top of the one-way turn plate fits with the bottom of the copper wire, and with the push of the pull rod, the one-way turn plate rotates, when the one-way turn plate moves to the top of the copper wire, the third motor drives the fixed frame to return, so that the pulling wheel is separated from the copper wire, at this time, the one-way turn plate returns under the action of the spring rod, and the one-way turn plate limits the copper wire; Step seven: The pulling rod moves downward, thereby pulling the copper wire downward. When the copper wire passes through the inner ring of the magnetic core, the side of the copper wire will fit with the side of the guide plate and slide downward along the guide plate, thereby avoiding the copper wire from fitting with the inner wall of the magnetic core and reducing the wear of the copper wire on the inside of the magnetic core. When the copper wire is pulled into the limit plate, the copper wire rotates around the outside of the magnetic core, and as the copper wire rotates, the copper wire moves out from under the one-way rotating plate, and the one-way rotating plate limits the copper wire. At this time, the fixed frame also moves back to the bottom of the magnetic core.
