Description

Technical Field

[0001] This application relates to the field of magnetic steel assembly technology, and in particular to an automatic magnetic steel feeding mechanism. Background Technology

[0002] The automated assembly process for magnets can be functionally divided into steps such as magnet feeding, magnet storage, magnet conveying, magnet separation, separator recycling, magnet specification identification, magnet positioning, and automatic magnet installation. Common magnet feeding mechanisms store magnets either flat or spread outwards along the rotor. The flat method is simple and suitable for small motor production where frequent feeding is not required. However, for rotor structures with a large number, variety, and weight of magnets, this flat structure has the disadvantage that the feeding mechanism must be stopped during magnet feeding, causing unnecessary waiting and affecting installation efficiency.

[0003] Therefore, how to avoid equipment downtime during magnet feeding is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

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

[0041] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 As shown, in this embodiment, an automatic magnetic steel feeding mechanism is provided. This mechanism includes a rotating magazine 1, magazine clips 2, a power assembly 3, and an ejection assembly 4. The rotating magazine 1 has several magazine clip mounting positions 14 distributed circumferentially, and multiple magazine clips 2 are detachably mounted at each magazine clip mounting position 14. The rotating magazine 1 is rotatable, thereby driving the magazine clips 2 to rotate to different magazine clip mounting positions 14. When the magazine clip 2 is mounted at a magazine clip mounting position 14, the rotating magazine 1 has the function of fixing the magazine clip 2.

[0043] The magazine 2 is used to store multiple magnets, and extends axially along the rotating magazine 1. A first notch 25 for the magnets 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 [reference needed]. 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 rotational power source for the rotating magazine 1 comes from the power assembly 3, which drives the rotating magazine 1 to rotate around a fixed axis. The ejection assembly 4 is fixedly installed at the axis of the rotating magazine 1. The ejection assembly 4 includes an actuating end 44 that moves radially along the rotating magazine 1. The actuating end 44 reciprocates at the second notch 27, so that after the actuating end 44 enters the second notch 27, it can push the magnet at the second notch 27 toward the first notch 25. Under the continuous pushing action, the magnet can be ejected from the first notch 25, which is convenient for subsequent magnet installation. In the reciprocating motion of the actuating end 44, the magnets in the magazine 2 can be ejected one by one, so that all the magnets can be extracted from the magazine 2.

[0045] As can be seen, the rotating magazine 1 of this application has multiple magazine mounting positions 14 for magazines 2. The magazines 2 are used to store magnets. The rotating magazine 1 is driven to rotate by the power component 3, so that the ejection component 4 can eject the magnets in different magazines 2. When it is necessary to refill a magazine 2, the magazine 2 to be refilled can be removed from the rotating magazine 1 individually without affecting the use of other magazines 2 in the rotating magazine 1. After refilling, it can be reinstalled into the rotating magazine 1, avoiding the problem of equipment downtime due to refilling magazines 2. At the same time, different specifications of magnets can be stored in different magazines 2 according to product requirements. Only the relevant dimensions of the magazines 2 need to be adjusted, which makes it highly versatile and widely applicable.

[0046] In some embodiments, the rotating magazine 1 includes a chassis 11 and a top plate 12 located on the upper side of the chassis 11. Please refer to... Figure 1and Figure 6 The chassis 11 and the top plate 12 are fixed together by a connector 13, such as a connecting plate, so that the rotating magazine 1 forms a cage structure. Furthermore, the chassis 11 and the top plate 12 are spaced apart axially in the rotating magazine 1, so that the interval forms a receiving space for accommodating 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, thereby fixing 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 can be disc-shaped structures, 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. The multiple 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 retaining edge 142 that protrudes axially from the opposite surfaces of the base plate 11 and the top plate 12 of the rotating magazine 1. The retaining edge 142 surrounds a receiving groove 141 that is adapted to the outer periphery of the end of the magazine 2. The receiving groove 141 has an opening on the radially outward side of the rotating magazine 1. The magazine 2 can be pushed into or pulled out of the receiving groove 141 radially along 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 the magazine mounting position 14, the outer wall of the end of the magazine 2 can also abut against the retaining edge 142. Thus, the magazine mounting position 14 can limit the magazine 2 in multiple directions (except for the radially outward direction).

[0049] Based on the above embodiment, a limiting handle 6 corresponding to the magazine mounting position 14 is also provided on the upper side of the top plate 12. Please refer to... Figure 1 and Figure 2 The limiting handle 6 includes a handle body, a limiting pin, a guide pin, and a return spring. The handle body is for manual pulling by the operator. The limiting pin is set on the handle body and moves through the top plate 12. It engages with the magazine 2 in the upper radial direction of the rotating magazine 1 to prevent the magazine 2 from disengaging from the magazine mounting position 14. In conjunction with the limiting effect of the magazine mounting position 14, the magazine 2 is detachably connected between the top plate 12 and the base plate 11, and the magazine 2 is fixed in the magazine mounting position 14.

[0050] Furthermore, a guide pin is disposed on the top plate 12, and the guide pin can penetrate the handle body, thereby guiding the handle body to move in a preset direction. A return spring is sleeved on the outer periphery of the guide pin, and the two ends of the return spring are respectively connected to the top plate 12 and the handle body. The return spring has an initial tension, thereby providing an elastic force for the limit pin to move to the locking position.

[0051] In use, the magazine 2 filled with magnets is pushed radially into the magazine mounting position 14. During the pushing process, the magazine 2 will squeeze the limiting pin and move upward, causing the limiting pin to disengage from its initial locking position. At the same time, the limiting pin drives the handle body to move upward and stretches the return spring. After the magazine 2 is installed in the magazine mounting position 14, the limiting pin automatically resets under the action of the return spring, realizing the radial locking and limiting of the limiting pin and the magazine 2, preventing the magazine 2 from accidentally disengaging from the magazine mounting position 14. When removing the magazine 2, the handle body is manually pulled to disengage the limiting pin from its locking position. At this time, the magazine 2 can be moved radially out. After removal, the handle body is manually released, and the handle body and the limiting pin automatically reset under the action of the return spring, so that the magazine 2 can be installed next time.

[0052] It should be noted that the radial limiting of the limiting pin and the magazine 2 can be a pin-hole limiting fit, that is, a limiting hole is opened on the magazine 2, and the limiting pin is inserted into the limiting hole to achieve the limiting snap-fit; or it can be a limiting fit of the limiting pin and the limiting block, to ensure that the radial snap-fit ​​limiting can be achieved, and not to affect the normal installation of the magazine 2. No further restrictions are imposed here, and both 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 position of each magazine 2 can be interchanged, so that each magazine 2 can reach a fixed magnet ejection position and a magazine 2 filling position. The magnet ejection position refers to the position of a magazine 2 when the ejection assembly 4 ejects the magnet from its contents; the magazine 2 filling position refers to the position of a magazine 2 when it is removed from the rotating magazine 1 to replenish its contents with magnets. The magnet ejection position and the magazine 2 filling position are different positions.

[0054] Please refer to Figures 3 to 5The magazine 2 includes a base plate 21 and side plates 22. The base plate 21 serves as the main support for the magazine 2. The side plates 22 are installed on both sides of the base plate 21, and the side plates 22 and the base plate 21 enclose a hollow groove that extends through both ends. Magnets are filled in this hollow groove. The magnets enter the hollow groove from the end of the magazine 2 near the top plate. After the magnets enter the hollow groove, they are confined within the hollow groove by a detachable partition 24 located at the end of the hollow groove near the top plate. The partition 24 is located at the end of the hollow groove to prevent the magnets from being discharged directly from the end of the hollow groove. The partition 24 can be detachably installed via the pressure plate 23 at the end of the side plate 22. The partition 24 is pressed tightly against the end of the side plate 22 by the pressure plate 23. When the strip-shaped magnets (the number of strip-shaped magnets can be customized according to the specific project needs, and the magnets are separated by spacers) need to be loaded into the hollow slot of the magazine 2, the partition 24 is removed, and the strip-shaped magnets are loaded into the hollow slot as a whole, and the magnets can move within the hollow slot.

[0055] The first notch 25 is located on the side plate 22 near the partition 24, and the corresponding second notch 27 is located on the bottom plate 21 near the partition 24. Under the limiting effect of the partition 24, the magnet in the hollow groove can only be discharged through the first notch 25.

[0056] In addition, a magnetic identification component 26 is provided on the outer surface of the base plate 21. Please refer to... Figure 5 The magnetic steel identification component 26 is used to detect the specifications of the magnetic steel in the hollow slot. The specifications of the magnetic steel in the same magazine 2 are the same. For example, the specifications of the magnetic steel can be determined according to the position of the magnetic steel identification component 26. Two magnetic steel identification components 26 are installed on the bottom plate 21 of the magazine 2. When neither magnetic steel identification component 26 detects a magnetic steel, it means that there is no magnetic steel in the magazine 2. When one magnetic steel identification component 26 detects a magnetic steel and the other does not detect a magnetic steel, it means that the magazine 2 contains the first type of magnetic steel. If both magnetic steel identification components 26 detect a magnetic steel, it means that the magazine 2 contains the second type of magnetic steel.

[0057] Different magnets can be stored in different magazines 2 according to product requirements. The mechanism automatically selects the corresponding magazine 2 as the feeding magazine 2 by identifying the specifications of the magnets in different magazines 2, and completes the automatic assembly of magnets in the rotor production process. In addition, weight reduction holes can be opened on the base plate 21 and / or side plate 22. By cooperating with the light box switch through the weight reduction holes, the mechanism can automatically determine whether magnets are filled in the magazine 2.

[0058] Considering that the hollow slot of the magazine 2 has openings at both ends, in order to prevent the strip of magnet from falling out from the side of the hollow slot near the chassis 11, the opening on that side of the hollow slot can be made smaller than the size of the magnet, but cannot be completely closed, so as to provide certain conditions for the push rod 54 of the subsequent push assembly 5 to enter the hollow slot of the magazine 2.

[0059] Please refer to Figure 2 The power assembly 3 includes a divider 33, a coupling 32, a geared motor 31, a turntable pad 34, bearings, etc. The geared motor 31 is connected to the divider 33 through the coupling 32. The divider 33 is connected to the chassis 11 through the turntable pad 34. The divider 33 controls the rotation angle of the rotating magazine 1 each time, so that the corresponding magazine 2 can accurately reach the magnet ejection position.

[0060] Please refer to Figure 1 and Figure 7 The component 4 includes a cylinder fixing plate 41 that is rotatably connected to the turntable pad 34 via a bearing. It is foreseeable that the cylinder fixing plate 41 itself does not rotate, but the cylinder fixing plate 41 and the turntable pad 34 are rotatably connected via the bearing, thereby ensuring the free rotation of the rotating magazine 1. At the same time, the rotation of the rotating magazine 1 is not affected by the cylinder fixing plate 41, nor does it affect the stability of the cylinder fixing plate 41.

[0061] It should be noted that the rotating magazine 1 of this application is a hollow cage structure, so the cylinder fixing plate 41 can be set at the center of the chassis 11, and a cylinder support 42 is set on the cylinder fixing plate 41. The cylinder support 42 is located inside the rotating magazine 1. A dual-axis cylinder 43 with an actuating end 44 is provided on the upper part of the cylinder support 42. The dual-axis cylinder 43 is located in the inner ring of the top plate 12. The actuating end 44 of the dual-axis cylinder 43 can move radially along the rotating magazine 1, so that the actuating end 44 can reciprocate in and out of the second notch 27.

[0062] When the magnet moves within the hollow slot to the side near the partition 24, the dual-axis cylinder 43 drives the actuating end 44 to push out a single magnet, thus achieving magnet separation. Each forward movement of the cylinder pushes the actuating end 44 forward once, propelling the magnet at the top of the magazine 2 through the first notch 25 to the robotic arm's gripping position. The cylinder then drives the actuating end 44 forward once more, pushing out the spacer at the top of the magazine 2, causing it to fall into the spacer recovery box below the mechanism.

[0063] The mechanism also 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 is pushed out while still in the top position of the magazine 2. Therefore, this application uses the pushing component 5 to enable the magnet to continuously move towards the top of the magazine 2, ensuring the effective pushing out of the magnet. Please refer to [link / reference needed] for details. Figure 2The pushing component 5 includes a fixed support plate 51 fixedly disposed below the chassis 11. The fixed support plate 51 is not fixedly connected to the chassis 11. The fixed support plate 51 is fixed in position and is used to provide stable support for the pushing component 5. The pushing component 5 also includes a servo motor 52 disposed on the fixed support plate 51. The output shaft of the servo motor 52 is connected to a lead screw 55 via a synchronous belt drive. The lead screw 55 is rotatably disposed on the fixed support plate 51. A slider 53 with a threaded engagement is sleeved on the outer periphery of the lead screw 55. A push rod 54 is fixedly disposed on the slider 53. The end of the push rod 54 can penetrate the chassis 11 and extend into the magazine 2, thereby pushing the magnet in the magazine 2 to move continuously toward the first notch 25.

[0064] In use, the displacement of the push rod 54 can be controlled by controlling the rotation angle of the servo motor 52, and the position of the magnet in the magazine 2 can be controlled at the same time. The initial position of the magnet can be preset. Subsequently, each time the dual-axis cylinder 43 pushes out the magnet, the push rod 54 advances a distance equal to the thickness of the magnet, then pushes out the partition again, and the push rod 54 advances another distance equal to the thickness of the partition until the last magnet is pushed out.

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

[0066] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
