An embodiment of the utility model provides a magnetic core loading attachment, as shown in fig. 1-5, it includes vibration dish 210, vibrator 250, pay-off track 240 and the screening track 230 that links to each other with pay-off track 240, but pay-off track 240 and screening track 230 integration link to each other. The vibratory tray 210 is used to carry magnetic cores and has vibratory tray tracks 220 for transporting the magnetic cores, the vibratory tray tracks 220 transporting the magnetic cores one by one in succession (since the vibratory tray tracks 220 are conventional components in the vibratory tray 210, the vibratory tray tracks 220 in the vibratory tray 210 are not illustrated by this application). The vibration disk track 220 can extend out of the vibration disk 210, the vibration disk track 220, the screening track 230 and the feeding track 240 are sequentially arranged along the feeding direction, the magnetic cores output from the vibration disk track 220 pass through the screening track 230 and then move to the feeding track 240, and the feeding track 240 can be in butt joint with the next station, so that the magnetic cores are conveyed to the next station, and automatic feeding is realized.

The vibrator 250 may be fixed to the bottom of the feeding rail 240, and since the screening rail 230 is connected to the feeding rail 240, the vibrator 250 may drive the feeding rail 240 and the screening rail 230 to vibrate, and the feeding rail 240 and the screening rail 230 may convey the magnetic core by vibration. The feeding rail 240 and the screening rail 230 may be generally provided in a linear type, and the vibrator 250 may be a linear vibrator.

The screening rail 230 includes a rail plate extending in the feeding direction, a rail groove 231 is provided on a surface of the rail plate to be abutted with the vibration plate rail 220, and a magnetic core output from the vibration plate rail 220 enters the rail groove 231. The rail groove 231 includes a bottom wall 232 and a side wall 233 for receiving the magnetic core, the bottom wall 232 is disposed to be inclined with respect to the vertical direction, the height of the bottom wall 232 in the width direction is gradually increased, and has a lower side and a higher side in the width direction, and the side wall 233 is disposed at the lower side of the bottom wall 232, so that the magnetic core will move above the connection position of the bottom wall 232 and the side wall 233.

The target magnetic core 11 and the non-target magnetic core 12 both move along the screening track 230, wherein the target magnetic core 11 is a magnetic core whose length direction is parallel to the feeding direction, and the non-target magnetic core 12 is a magnetic core whose length direction is not parallel to the feeding direction. A material passing groove 234 for passing only the target magnetic core 11 is provided on the bottom wall 232, and the material passing groove 234 is butted against the feeding rail 240, so that the target magnetic core 11 enters the material passing groove 234 and moves along the material passing groove 234 to the feeding rail 240. The non-target magnetic core 12 cannot enter the material passing groove 234, and it continues to move along the track groove 231, and the non-target magnetic core 12 will eventually fall from the blanking notch 235 due to the blanking notch 235 provided on the side wall 233. Therefore, the feeding rail 240 of the embodiment finally outputs the magnetic cores arranged along the same direction, the whole process is realized by mechanical automation, and the production efficiency is greatly improved.

For the use situation that the magnetic core needs to face upward, the front-back screening mechanism may be further disposed on the vibration disk track 220 in the present embodiment, so that the magnetic core finally output by the vibration disk track 220 faces upward. The magnetic cores conveyed to the screening rails 230 face uniformly, and are finally conveyed out by the feeding rails 240 after being screened by the screening rails 230 and face upwards and arranged along the length direction, so that pad printing operation is facilitated.

The magnetic core feeding device of the present embodiment may further include a machine 100, and the vibration plate 210, the screening rail 230, and the feeding rail 240 may be fixed on the machine 100. A first bracket 251 may be provided on the machine table 100, and a vibrator 250 may be fixed to the first bracket 251 to raise the screening rail 230 and the feeding rail 240 to a certain height so as to be in contact with the vibration plate rail 220. A plurality of rollers 101 may be disposed at the bottom of the machine table 100 so as to move the entire magnetic core feeding device.

In this embodiment, the bottom wall 232 is provided with a protruding screening flange 236, the bottom wall 232 and the side wall 233 enclose to form the passing groove 234, and a part of the track groove 231 forms the passing groove 23, so that the target magnetic core 11 can enter the passing groove 234 more smoothly.

In this embodiment, one end of the screening convex plate 236 close to the vibrating tray track 220 is provided with a guiding slope 237, and the guiding slope 237 is set as follows: in the feeding direction, the distance of the guide slope 237 protruding from the bottom wall 232 gradually increases, and the non-target magnetic core 12 that cannot enter the material passing groove 234 gradually moves away from the material passing groove 234 along the guide slope 237 and finally falls off from the material falling notch 235. The gradually protruding structure can effectively avoid material blocking, and the magnetic core is more smoothly transported.

Specifically, the guiding slope 237 may be an arc structure, and the surface of the guiding slope is smoother, so as to facilitate the material transportation of the non-target magnetic core 12.

Meanwhile, the material guiding slope 237 is closer to the vibrating tray track 220 than the material dropping notch 235. Therefore, the target core 11 and the non-target core 12 are separated before the blanking, which can avoid the situation that the non-target core 12 cannot fall from the blanking gap 235.

Further, the bottom wall 232 and the side wall 233 are perpendicular to each other, as shown in fig. 4, the cross-sectional shape of the track groove 231 may be "L" shaped, which is more suitable for transporting a magnetic core having an outline similar to a rectangular parallelepiped structure, and may be more matched with the outline of the magnetic core, thereby facilitating the transportation of the magnetic core.

Furthermore, the track plate is disposed parallel to the bottom wall 232, so that the track plate is also disposed obliquely, and is more matched with the structure of the obliquely disposed through-slot 234, so as to facilitate the non-target magnetic core 12 to fall from the blanking notch 235.

When the track plate is obliquely arranged, considering that the obliquely arranged magnetic core is not beneficial to the production operation of the next process, the track plate positioned on the feeding track 240 can be configured to be gradually rotated to the horizontally arranged state along the feeding direction, so that the magnetic core output by the feeding track 240 is in the normal horizontally arranged state, and the production operation of the next station is facilitated.

The vibration disk track 220 may include two vibration disk track plates 221, the two vibration disk track plates 221 are respectively disposed in parallel with the bottom wall 232 and the side wall 233, and upper surfaces of the two vibration disk track plates 221 are respectively flush with the bottom wall 232 and the side wall 233, so that the magnetic core may smoothly move from the vibration disk track 220 to the screening track 230. Therefore, the track structure of the embodiment is open, and compared with a closed track structure, the track structure can enable material transportation to be smoother.

In this embodiment, the feeding track 240 and the screening track 230 may be integrally connected, the track plate extends to the feeding track 240, and the material passing groove 234 extends to the track plate located on the feeding track 240, so that the magnetic core continuously moves in the material passing groove 234 and finally can be output from the feeding track 240. The feeding rail 240 is provided with a rail baffle 241 extending along the extending direction of the material passing groove 234, and the rail baffle 241 covers at least a part of the material passing groove 234 of the feeding rail 240. Because the feeding track 240 is long, the magnetic cores may be sequenced wrongly or separated from the material passing groove 234 in the moving process, and the track baffle 241 has a limiting effect on the magnetic cores in the material passing groove 234, so that the magnetic cores are conveyed along the length direction of the magnetic cores, and the magnetic cores can be prevented from being separated from the material passing groove 234.

In this embodiment, the magnetic core feeding device further comprises a feeding mechanism, and the feeding mechanism comprises a hopper 260, a blanking plate 270 and a vibrating mechanism 280. The hopper 260 has an opening at the bottom, which is located above the blanking plate 270, and the blanking plate 270 has a blanking slot into which the magnetic core in the hopper 260 can fall from the opening. The blanking groove has a blanking groove outlet for the magnetic core to move out of the blanking groove, the blanking groove outlet is positioned above the vibration disc 210, the vibration mechanism 280 is fixed on the blanking plate 270 and drives the blanking plate 270 to vibrate, so that the magnetic core on the blanking plate 270 moves towards the blanking groove outlet, and the magnetic core finally falls into the vibration disc 210, so that the material can be supplemented to the vibration disc 210, and the phenomenon that the magnetic core feeding device stops feeding and affects the production efficiency is avoided. The driving principle of the vibration mechanism 280 may be the same as that of the vibrator 250 of the above-described embodiment. In this embodiment, the machine 100 is provided with a second support 261, and the feeding mechanism can be fixed on the second support 261.

Further, the feeding mechanism further comprises a controller and a magnetic core detection mechanism 292 for detecting whether the magnetic core in the vibration disk 210 is sufficient, and both the magnetic core detection mechanism 292 and the vibration mechanism 280 are electrically connected with the controller. Under the acquiescence state, vibration mechanism 280 does not work, therefore the magnetic core can not be carried to vibration dish 210, when magnetic core detection mechanism 292 detected the magnetic core of vibration dish 210 not short of material, it sent inductive signal to the controller, and the controller sends control signal to vibration mechanism 280 according to this inductive signal, makes vibration mechanism 280 begin to work, and the magnetic core just can fall into vibration dish 210, and this just can realize automatic feed supplement, need not artifical too much supervision, and is more intelligent.

In the present embodiment, the bottom wall of the vibration plate 210 is gradually protruded in the radial direction and toward the center of the vibration plate 210, and the magnetic core is more easily slid away from the center of the vibration plate 210 to be accumulated at the position of the vibration plate 210 near the periphery, since the vibration plate track 220 is generally spiral-shaped and distributed at the position of the vibration plate 210 near the periphery, which makes the magnetic core more easily enter the vibration plate track 220.

Magnetic core detection mechanism 292 is infrared distance sensor, can set up on the second support 261 and detect dead lever 291, and detection dead lever 291 one end can be fixed on second support 261, and the other end is fixed with this infrared distance sensor, and infrared distance sensor shines light to the bottom of vibration dish 210. When the irradiation position of the infrared distance sensor has no magnetic core, the distance detected by the infrared distance sensor becomes smaller, so that the shortage of the vibrating tray 210 can be judged.

In this embodiment, the material passing groove 234 is configured to: the width of the material passing groove 234 is matched with the width of the magnetic core, and may be slightly larger than the width of the magnetic core, and the width of the material passing groove 234 is smaller than the length of the magnetic core. Therefore, when the length direction of the magnetic cores is parallel to the extending direction of the material passing groove 234, the magnetic cores can enter the material passing groove 234, and when the length direction of the magnetic cores is not parallel to the extending direction of the material passing groove 234, the magnetic cores cannot enter the material passing groove 234, so that the screening in the sorting direction of the magnetic cores can be realized.

In the present embodiment, the receiving box 222 for receiving the magnetic core dropped from the blanking notch 234 is provided below the blanking notch 234, so that the non-target magnetic core 12 does not directly drop to the ground, and the collected magnetic core can be placed in the vibration tray 210 again, thereby reducing material loss.
