Description

Technical Field

[0001] The utility model relates to the field of winding machines, in particular to a double-station differential mode magnetic winding machine. Background Art

[0002] Magnetic toroidal coil winding machines are key equipment in the electronic component manufacturing industry, widely used in electronics, communications, power, and automation control. Primarily used to wind the coils of toroidal inductors, they are crucial for the manufacture of electronic components such as toroidal transformers, filters, and inductors. Magnetic toroidal coil winding machines guarantee the performance and quality of electronic components by precisely controlling the winding pattern and number of layers, while ensuring the uniformity and tightness of the coils.

[0003] Existing magnetic coil winding machines typically consist of a machine head, fixture, and base, with functions such as securing the magnetic coil, threading the wire, and winding with a robotic arm. In actual operation, workers secure the magnetic coil to the fixture, and the robotic arm winds the wire along a pre-set path and number of layers. The entire winding process requires consistent wire tension, speed, and position to ensure coil quality.

[0004] However, existing magnetic ring winding machines have some obvious defects during use. First, existing magnetic ring winding machines can usually only wind one magnetic ring product at a time, which cannot meet the needs of large-scale production, resulting in low production efficiency during the winding process. In addition, the existing magnetic ring winding process usually uses a clamp to continuously clamp and rotate the magnetic core, and the existing clamp mechanism used to clamp the magnetic core for winding is prone to aging, resulting in a short service life of the equipment. The existing clamp is prone to affecting the structure of the magnetic core under the continuous clamping and rotating action. The force exerted by the rotating clamp on the magnetic core causes the magnetic core to wear easily, affecting the winding production, which is not conducive to the stability and reliability of the magnetic ring, thereby affecting the production efficiency and production quality of the magnetic ring.

[0051] Specifically, the sliding member 301 in this embodiment is a slide rail and a slider mounted on the slide rail in a matching manner, and the swing device 20 is a spherical bearing.

[0052] Reference Figure 7 The positioning clamp 200 includes a movable cylinder 201 and a clamping cylinder 202 mounted on the movable cylinder 201. The movable cylinder 201 is mounted on the workbench 2 via a connecting plate 203. The clamping cylinder 202 can move along the extension and contraction direction of the movable cylinder 201, and the clamping end of the clamping cylinder 202 extends toward the center of the indexing mounting seat 3. The arrangement of the clamping cylinder 101 and the clamping cylinder 202 can reduce large-angle rotational wear on the magnetic core and reduce the clamping effect on the clamping end of the clamping cylinder 101, thereby increasing its service life and enhancing the clamping force and winding effect of the magnetic ring.

[0057] Specifically, the tail wire clamping claws 12 of the swing frame 11 rotate to form an inclined stretching after clamping the copper wire, thereby reducing the occupied space of the winding machine.

[0060] Specifically, how the winding mechanism in this embodiment drives the winding is a conventional technical means of those skilled in the art and will not be elaborated in detail here.

The detector 603 and the feeding wheel 602 are both installed on the connecting seat 601.

[0065] The difference between this embodiment and the prior art is that:

[0066] Loading: Use the vibrating material tray 501 to vibrate the magnetic core and transport the magnetic core to the material distribution fixture 503 through the magnetic core feeding block 504. Through the coordinated movement of the X-axis moving module 13 and the Y-axis moving module 13, the magnetic core feeding clamp 16 clamps the magnetic core and transports it to the magnetic winding station 1 and the magnetic winding station 2. Through the coordinated movement of the X-axis moving module 13 and the Y-axis moving module 13, the copper wire passes through the detector 603 and the wire wheel, and passes through the copper wire clamping device. It is clamped by the copper wire feeding clamp 17 and transported to the magnetic winding station 1 and the magnetic winding station 2, and the copper wire is cut using a scissor cylinder;

[0067] Winding: The magnetic core is clamped by the clamping cylinder 101, and the copper wire is wound onto the magnetic core through the winding device. When the magnetic core is wound with part of the copper wire, the magnetic core needs to be rotated. The clamping cylinder 202 is driven by the moving cylinder 201 to move to the center of the indexing mounting seat 3. The clamping end of the clamping cylinder 202 clamps the magnetic core on the clamping cylinder 101 up / down. The clamping cylinder 101 loosens the clamping of the magnetic core and is driven by the driving motor 304. The rotating seat 102 drives the clamping cylinder 101 to rotate a certain angle, and the clamping cylinder 101 clamps the outer side of the magnetic core clamped by the clamping cylinder 202. The upper / lower clamping end of the clamping cylinder 202 is released, and the driving motor 304 drives the rotating seat 102 to rotate in the reverse direction or reset, so that the rotating seat 102 drives the clamping cylinder 101 holding the magnetic core to rotate, so that the subsequent winding action can be carried out. Repeat the above winding action to complete the winding work;

[0068] In this embodiment, when the copper wire passes through the wire groove 6 and hooks downward on the wire hooking shaft 9, the swing frame 11 can be driven to rotate and swing by the rotating reducer 10. When the end of the swing frame 11 equipped with the tail wire clamp 12 rotates close to the wire protection device 5, the tail wire clamp 12 on the swing frame 11 can clamp the copper wire and pull it under the reverse rotation of the rotating reducer 10, thereby stretching the length of the copper wire, thereby facilitating winding.

[0069] By setting up the clamping cylinder 202 and the holding cylinder 101, it is possible to reduce the wear of the clamping end of the holding cylinder 101 itself and reduce the influence of the clamping end of the holding cylinder 101 on the excessive clamping force of the magnetic core, thereby avoiding the wear problem of the magnetic core caused by uneven force, improving the stability and reliability of the magnetic core, and further improving the production quality and production efficiency of the magnetic ring.
