Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1 to 9, an embodiment of the present invention provides a magnetic ring feeding mechanism, configured to feed a magnetic ring 1 having a residual portion 11 on an outer side wall, and including a frame 2, where the frame 2 is provided with: the magnetic ring feeding device comprises a guide piece 3, a feeding device, an adjusting device and a discharging device, wherein a guide groove 31 for the magnetic ring 1 to roll in is formed in the guide piece 3, and a feeding position and a discharging position are arranged in the guide groove 31; the feeding device comprises a blanking mechanism and a carrying mechanism which can convey the magnetic rings 1 of the blanking mechanism to the feeding positions of the guide grooves 31 one by one; the adjusting device is used for driving the magnetic ring 1 to move from the feeding position to the discharging position of the guide groove 31 and driving the magnetic ring 1 to rotate in the process so that the residual part 11 faces downwards; the discharging device is used for clamping the magnetic ring 1 at the material level and conveying the magnetic ring 1 to the outside of the guide groove 31.

In a preferred embodiment of the present invention, the feeding position and the discharging position of the guide groove 31 are respectively located at two ends of the guide groove, the guide groove 31 is gradually raised along the direction from the feeding position to the discharging position, the adjusting device comprises a linear vibrating feeder 4 arranged on the frame 2, and the vibration generated by the linear vibrating feeder 4 acts on the guide member 3 to drive the magnetic ring 1 in the guide groove 31 to be obliquely conveyed upwards along the guide groove 31.

Alternatively, the bottom surface of the linear vibration feeder 4 is parallel to the vibration conveying direction thereof, the frame 2 is provided with an inclined mounting surface 201, and the linear vibration feeder 4 is obliquely mounted on the mounting surface 201 through the bottom surface thereof so as to be obliquely upward in the vibration conveying direction.

The guide 3 is installed on the top of the linear vibration feeder 4, and the bottom surface of the guide groove 31 is an inclined plane and is parallel to the vibration conveying direction of the linear vibration feeder 4. Of course, in other embodiments of the present invention, the guide groove may be formed as an inclined arc surface.

Referring to fig. 1 and 2, the opening of the guide groove 31 is located at the front side thereof, the baffle plate 8 capable of limiting the magnetic ring 1 in the guide groove 31 from falling out of the opening is detachably mounted on the vibration receiving member 3, and the baffle plate 8 and the vibration receiving member 3 are preferably connected together in a threaded manner.

Only the linear vibration feeder 4 is adopted to drive the magnetic ring 1 to move, the debugging process is very difficult, when the vibration power is too small, the magnetic ring 1 cannot be conveyed to the discharge end of the guide groove 31 due to insufficient power, and when the vibration power is too large, the magnetic ring 1 can always rotate and cannot be stopped when the incomplete part 11 faces downwards.

In order to solve the above problem, the baffle plate 8 is provided with an air inlet slot 51 facing the guide slot 31, and the front side of the baffle plate 8 is provided with an air blowing device which blows air into the guide slot 31 through the air inlet slot 51 to apply a driving force to the magnetic ring 1 in the guide slot 31 to move towards the discharging position. In this embodiment, the blowing device includes an air pipe 82 provided at the front side of the baffle 8, the air pipe 82 is connected to an air source such as a high-pressure air chamber (not shown), and the air pipe 82 is further connected to a switch valve (not shown) for controlling on/off of the air pipe 82. The driving force is increased by adopting a blowing mode, the blowing power is convenient to adjust, and the magnetic ring 1 can be accurately stopped when rotating to the downward direction of the incomplete part 11 by matching with smaller vibration power and then smoothly conveyed to the discharge end of the guide groove 31.

Furthermore, the vibration receiving piece 3 is provided with an auxiliary feeding groove 34 which can feed the magnetic ring 1 into the guide groove 31. In the debugging process, the performance of the feeding device is unstable, and the debugging can be carried out in a mode that the magnetic ring 1 is added into the guide groove 31 through the auxiliary feeding groove 34.

Referring to fig. 9, as a further improvement of the present invention, a guide 3 is installed on the top of the linear vibration feeder 4, and a locking structure is provided between the guide 3 and the linear vibration feeder 4.

In this embodiment, the anti-loosening structure includes a clamping groove 33 provided at the bottom of the guide 3 and a top plate 41 provided at the top of the linear vibration feeder 4, the clamping groove 33 is a through groove perpendicular to the guide groove 31, and all or a part of the top plate 41 is fitted in the clamping groove 33 and abuts against the inner side wall of the clamping groove 33.

When receiving the vibration, guide 3 has the trend of removing along the vibration direction, and adopts such structure can carry out spacingly to guide 3, avoids guide 3 to remove and produces not hard up.

The width of the guide groove 31 is slightly larger than that of the magnetic ring 1, and when the magnetic ring 1 is placed in the guide groove 31, the outer side wall of the magnetic ring 1 is grounded and can roll. Taking the incomplete part 11 as an inward concave notch as an example, after the magnetic ring 1 is placed at the head end of the guide groove 31, the magnetic ring moves upwards in an inclined manner towards the tail end of the guide groove 31 due to the driving of the linear vibration feeder 4, and the moving process is divided into two stages. In the first stage, because friction exists between the bottom surface of the guide groove 31 and the outer side wall of the magnetic ring 1, the magnetic ring 1 moves and rotates at the same time until the two side edges of the residual part 11 touch the ground, and at the moment, the residual part 11 faces downwards; in the second stage, after the incomplete part 11 faces downwards, the magnetic ring 1 does not rotate any more, and at this time, under the driving action of the linear vibration feeder 4, the magnetic ring 1 moves in a translational manner and inclines upwards along the guide groove 31. When the magnetic ring 1 moves to the material discharging position at the upper end of the guide groove 31, the discharging device works to clamp the magnetic ring 1 and convey the magnetic ring 1 to the target position outside the guide groove 31, and finally the magnetic ring 1 is clamped by a clamp of the winding mechanism. The feeding device is adopted to place the magnetic rings 1 into the guide groove 31 one by one, so that the phenomenon that more than two magnetic rings 1 are pushed in the guide groove 31 and cannot stop rotating when the incomplete part 11 faces downwards can be avoided. In summary, the structure of the invention is simple, the position of the magnetic ring 1 can be automatically adjusted in the feeding process through the invention, so that the incomplete parts 11 on the magnetic ring 1 all face to the same fixed direction when the magnetic ring 1 is fed out from the discharging device, the clamp of the winding mechanism is conveniently clamped on one side of the incomplete parts 11 to automatically wind in other positions on the magnetic ring 1, and the working efficiency and the excellent rate of the produced coils are improved.
