It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0041] To enable those skilled in the art of this technology to better understand the solution of this application, the following provides a further detailed description of this application in conjunction with the accompanying drawings and specific embodiments.

[0042] As Figure 1 shown, in this embodiment, a magnetic steel automatic feeding mechanism is provided. The mechanism includes a rotating magazine 1, a magazine 2, a power assembly 3, and a pushing assembly 4. The rotating magazine 1 is circumferentially provided with a plurality of magazine mounting positions 14, and a plurality of magazines 2 are respectively detachably arranged at the magazine mounting positions 14; the rotating magazine 1 is rotatably arranged, so as to drive the magazine 2 to rotate to different magazine mounting positions 14. Among them, when the magazine 2 is assembled at the magazine mounting position 14, the rotating magazine 1 has the function of fixing the magazine 2.

[0043] The interior of the magazine 2 is used to store a plurality of magnetic steels, and the magazine 2 extends along the axial direction of the rotating magazine 1. A first notch 25 for the magnetic steel to pass through is provided on the radially outward side of the magazine 2 along the rotating magazine 1, and a second notch 27 is provided on the radially inward side of the magazine 2 along the rotating magazine 1. Please refer to Figure 3 and Figure 4 , the first notch 25 and the second notch 27 are located on two opposite surfaces of the magazine 2, and their positions correspond to each other.

[0044] The rotation power source of the rotating magazine 1 comes from the power assembly 3, so as to drive the rotating magazine 1 to rotate around a fixed axis; the pushing assembly 4 is fixedly arranged at the axis of the rotating magazine 1. The pushing assembly 4 includes an action end 44 that moves radially along the rotating magazine 1. The action end 44 reciprocates at the second notch 27. After the action end 44 enters the second notch 27, the magnetic steel at the second notch 27 can be pushed towards the first notch 25. Under the continuous pushing action, the magnetic steel can be exported from the first notch 25, which is convenient for subsequent magnetic steel installation. And under the reciprocating movement of the action end 44, the magnetic steels in the magazine 2 can be pushed out one by one, realizing the export of all the magnetic steels from the magazine 2.

[0045] It can be seen that the rotating magazine 1 of this application has a plurality of magazine mounting positions 14 for the magazines 2. The magazines 2 are used to store magnetic steels. The power assembly 3 drives the rotating magazine 1 to rotate, so that the pushing assembly 4 can push out the magnetic steels in different magazines 2; when the magazine 2 needs to be filled, the magazine 2 to be filled can be separately taken out from the rotating magazine 1, which does not affect the use of other magazines 2 in the rotating magazine 1. After filling, it can be reinstalled into the rotating magazine 1 again, avoiding the problem of equipment shutdown caused by filling the magazine 2. At the same time, in different magazines 2, magnetic steels of different specifications can be stored according to product requirements, and only the relevant dimensions of the magazine 2 need to be adjusted, with strong versatility and wide applicability.

[0046] In some embodiments, the rotating magazine 1 includes a chassis 11 and a top plate 12 located above the chassis 11. Please refer to Figure 1and Figure 6 The chassis 11 and the top plate 12 are fixed through a connecting member 13. For example, the connecting member 13 is a connecting plate, etc., so that the rotating magazine 1 forms a cage structure. Further, the chassis 11 and the top plate 12 are spaced apart in the axial direction of the rotating magazine 1, so that the space formed by the spacing is used as a receiving space for the magazine 2, and the magazine mounting positions 14 are symmetrically arranged on the opposite surfaces of the chassis 11 and the top plate 12, so as to fix the magazine 2 in the receiving space between the chassis 11 and the top plate 12.

[0047] It should be noted that the chassis 11 and the top plate 12 may be in a disc-shaped structure, and the rotation axis of the rotating magazine 1 is located at the center of the chassis 11 and the top plate 12, so that the rotating magazine 1 rotates around its own central axis; at the same time, the magazine mounting positions 14 distributed along the axial direction of the rotating magazine 1 can also rotate around the central axis of the rotating magazine 1. And a plurality of magazines 2 are distributed on corresponding distribution circles with the central axis of the rotating magazine 1 as the center.

[0048] Please refer to Figure 6 , the magazine mounting position 14 includes a rib 142 protruding from the opposite surfaces of the chassis 11 and the top plate 12 in the axial direction of the rotating magazine 1. The rib 142 encloses a receiving groove 141 adapted to the outer peripheral contour of the end of the magazine 2, and an opening is provided on one side of the receiving groove 141 extending radially outward of the rotating magazine 1. The magazine 2 can be pushed into or pulled out of the receiving groove 141 along the radial direction of the rotating magazine 1 through the opening. After the magazine 2 enters the receiving groove 141, both ends of the magazine 2 can abut against the bottom of the receiving groove 141; at the same time, after the magazine 2 is installed in place at the magazine mounting position 14, the outer wall of the end of the magazine 2 can also abut against the rib 142, so as to realize the limit of the magazine 2 in multiple directions (except the radially outward direction) through the magazine mounting position 14.

[0049] On the basis of the above embodiments, a limit handle 6 corresponding to the magazine mounting position 14 one by one is further provided on the upper side of the top plate 12. Please refer to Figure 1 and Figure 2 , the limit handle 6 includes a handle body, a limit pin, a guide pin and a return spring. The handle body is for the operator to manually pull. The limit pin is arranged on the handle body. The limit pin movably penetrates the top plate 12 and is in a limit clamping connection with the magazine 2 in the radial direction of the rotating magazine 1 to limit the magazine 2 from disengaging from the magazine mounting position 14; and in cooperation with the limiting effect of the above magazine mounting position 14, the detachable connection of the magazine 2 between the top plate 12 and the chassis 11 is realized, and the fixing effect of the magazine 2 at the magazine mounting position 14 is realized.

[0050] Furthermore, the guiding pin is arranged on the top plate 12. The guiding pin can penetrate through the handle body, so as to guide the handle body to move along a preset direction. The reset spring is sleeved on the outer periphery of the guiding pin. Two ends of the reset spring are respectively connected to the top plate 12 and the handle body. The reset spring has an initial stretching amount, so as to provide an elastic force for the limit pin to move towards the clamping position.

[0051] During use, the magazine 2 filled with magnetic steel is pushed radially into the magazine installation position 14. During the pushing process, the magazine 2 will squeeze the limit pin to move upward, resulting in the limit pin disengaging from the initial clamping position. At the same time, the limit pin drives the handle body to move upward and stretches the reset spring; when the magazine 2 is installed in place in the magazine installation position 14, the limit pin automatically resets under the action of the reset spring, realizing the radial clamping limit between the limit pin and the magazine 2 to prevent the magazine 2 from accidentally falling out of the magazine installation position 14; when removing the magazine 2, manually pull the handle body to make the limit pin disengage from the clamping position. At this time, the magazine 2 can be removed radially. After taking it out, manually release the handle body, and the handle body and the limit pin automatically reset under the action of the reset spring for the next installation of the magazine 2.

[0052] It should be noted that the radial limit between the limit pin and the magazine 2 can be the limit fit between the pin and the hole, that is, a limit hole is opened on the magazine 2, and the limit clamping is realized through the insertion of the limit pin into the limit hole; it can also be the limit fit between the limit pin and the limit block, ensuring that the radial clamping limit can be realized and the normal installation of the magazine 2 is not affected. There are no excessive restrictions here, and all fall within the protection scope of this application.

[0053] In some embodiments, the magazines 2 can be axially symmetrically distributed in the rotating magazine 1. When the rotating magazine 1 drives the magazines 2 to rotate, the positions of each magazine 2 can be replaced with each other, so that each magazine 2 can reach a fixed magnetic steel pushing position and a magazine 2 filling position. Among them, the magnetic steel pushing position refers to the position where the magazine 2 is located when the pushing component 4 pushes out the magnetic steel in a certain magazine 2; the magazine 2 filling position refers to the position where a certain magazine 2 is taken out from the rotating magazine 1 to replenish the magnetic steel into the magazine 2; the magnetic steel pushing position and the magazine 2 filling position are different positions.

[0054] Please refer to Figures 3 to 5, the magazine 2 includes a bottom plate 21 and side plates 22. The bottom plate 21 serves as the main support of the magazine 2, and the side plates 22 are installed on both sides of the bottom plate 21. The side plates 22 and the bottom plate 21 enclose a hollow groove that penetrates at both ends, and the magnet is filled in this hollow groove. Among them, the magnet enters the hollow groove from one end of the magazine 2 close to the top plate. After the magnet enters the hollow groove, a removable partition 24 on the side of the magazine 2 close to the top plate restricts the magnet in the hollow groove. The partition 24 is located at the end of the hollow groove to prevent the magnet from directly discharging from the end of the hollow groove. The partition 24 can be detachably installed by a pressing plate 23 provided at the end of the side plate 22. The partition 24 is pressed against the end of the side plate 22 by the pressing plate 23. When a strip-shaped magnet (the number of strip-shaped magnets can be customized according to specific project requirements, and the magnets are isolated by spacer sheets) needs to be loaded into the hollow groove of the magazine 2, the partition 24 is removed, and the strip-shaped magnet is integrally loaded into the hollow groove, and the magnet can move in the hollow groove.

[0055] Among them, a first notch 25 is provided on one side of the side plate 22 close to the partition 24, and a corresponding second notch 27 is provided on one side of the bottom plate 21 close to the partition 24. Under the limiting action of the partition 24, the magnet in the hollow groove can only be exported through the first notch 25.

[0056] In addition, a magnet identification member 26 is also provided on the outer surface of the bottom plate 21. Please refer to Figure 5 , the magnet identification member 26 is used to detect the specification of the magnet in the hollow groove, and the specifications of the magnets in the same magazine 2 are the same; for example, the magnet specification can be judged according to the position of the magnet identification member 26. Two magnet identification members 26 are installed on the bottom plate 21 of the magazine 2. When neither of the two magnet identification members 26 detects a magnet, it means that there is no magnet in the magazine 2. When one of the magnet identification members 26 detects a magnet and the other does not, it means that the first type of magnet is stored in the magazine 2; if both magnet identification members 26 detect a magnet, it means that the second type of magnet specification is stored in the magazine 2.

[0057] In different magazines 2, different magnets can be stored according to product requirements. This mechanism automatically selects the corresponding magazine 2 as the feeding magazine 2 by identifying the magnet specifications in different magazines 2 to complete the automatic assembly of the magnets during the rotor production process; in addition, weight-reducing holes can also be opened on the bottom plate 21 and / or the side plates 22. By cooperating with the grating switch through the weight-reducing holes, this mechanism can automatically judge whether the magazine 2 is filled with magnets.

[0058] Considering that both ends of the hollow groove of the magazine 2 are open, to prevent the strip-shaped magnet from falling out from the side of the hollow groove close to the chassis 11, the opening on this side of the hollow groove can be made smaller than the size of the magnet, but not completely closed, to provide certain conditions for the ejector rod 54 of the subsequent pushing component 5 to enter the hollow groove of the magazine 2.

[0059] Please refer toFigure 2 The power assembly 3 includes a divider 33, a coupling 32, a reduction motor 31, a turntable backing plate 34, bearings, etc. The reduction motor 31 is connected to the divider 33 through the coupling 32. The divider 33 is connected to the chassis 11 through the turntable backing plate 34. The rotation angle of the rotary magazine 1 is controlled by the divider 33 each time, so that the corresponding magazine 2 can accurately reach the magnet pushing position.

[0060] Please refer to Figure 1 and Figure 7 The pushing assembly 4 includes a cylinder fixing plate 41 rotatably connected to the turntable backing plate 34 through a bearing. It can be predicted that the cylinder fixing plate 41 itself does not rotate, and the rotation connection between the cylinder fixing plate 41 and the turntable backing plate 34 is realized through the bearing, so as to ensure the free rotation of the rotary magazine 1. At the same time, the rotation of the rotary magazine 1 is not affected by the cylinder fixing plate 41, nor will it affect the stability of the cylinder fixing plate 41.

[0061] It should be noted that the rotary magazine 1 of the present application is a hollow cage structure. Therefore, the cylinder fixing plate 41 can be arranged at the central position of the chassis 11. At the same time, a cylinder support 42 is arranged on the cylinder fixing plate 41. The cylinder support 42 is located inside the rotary magazine 1. A double-axis cylinder 43 with an action end 44 is arranged on the upper part of the cylinder support 42. The double-axis cylinder 43 is located inside the inner ring of the top plate 12. The action end 44 of the double-axis cylinder 43 can move radially along the rotary magazine 1, so that the action end 44 can reciprocate in and out of the second notch 27.

[0062] When the magnet runs in the hollow groove to the side close to the partition 24, the action end 44 is driven by the double-axis cylinder 43 to push out the single-piece magnet, and the magnet separation can be realized. The cylinder moves forward once, driving the action end 44 to push forward once, and pushing the magnet at the top of the magazine 2 forward through the first notch 25 to the robot grasping position; the cylinder then drives the action end 44 to move forward once again, pushing out the spacer at the top of the magazine 2 at this time, so that the spacer falls into the spacer recovery box below the mechanism.

[0063] The mechanism further includes a pushing component 5. Since the first notch 25 and the second notch 27 are located at the top of the magazine 2, it is necessary to ensure that the magnet can be pushed out at the top position of the magazine 2. Therefore, the present application adopts the pushing component 5 to enable the magnet to continuously move towards the top of the magazine 2 to ensure the pushing effect of the magnet. For details, please refer to Figure 2, the pushing component 5 includes a fixed support plate 51 fixedly arranged below the chassis 11. The fixed support plate 51 is not fixedly connected to the chassis 11. The position of the fixed support plate 51 is fixed and is used to provide stable support for the pushing component 5. The pushing component 5 further includes a servo motor 52 arranged on the fixed support plate 51. The output shaft of the servo motor 52 is drivingly connected to a lead screw 55 through a synchronous belt. The lead screw 55 is rotatably arranged on the fixed support plate 51, and a slider 53 threadedly engaged with the lead screw 55 is sleeved on the outer periphery of the lead screw 55. A push rod 54 is fixedly arranged on the slider 53. The end of the push rod 54 can penetrate through the chassis 11 and extend into the magazine 2, so as to push the magnets in the magazine 2 to continuously move towards the position of the first notch 25.

[0064] During use, by controlling the rotation angle of the servo motor 52, the displacement of the push rod 54 can be controlled, and at the same time, the position of the magnets in the magazine 2 can be controlled. The initial position of the magnets can be preset. Each time the biaxial cylinder 43 pushes out a magnet, the push rod 54 advances a distance equal to the thickness of one magnet, and then when a spacer is pushed out, the push rod 54 advances a distance equal to the thickness of one spacer until the last magnet is pushed out.

[0065] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0066] In this article, specific examples are used to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
