[0002] In the existing production of three-phase electromagnetic products, a large number of silicon steel sheets need to be crimped to realize the assembly of the iron core. Based on certain requirements of the assembly process, for example, the need to facilitate the gluing of the iron core or the removal of the iron core, the frame used to hold the iron core usually has a plurality of relatively arranged openings. In the process of placing the silicon steel sheets that make up the iron core, a movable plate is required to block one of the openings to support the silicon steel sheets; and during or after the assembly of the iron core, the movable plate is removed to glue the iron core on multiple sides or to perform the removal operation.

[0003] When the movable plate supports the silicon steel sheet, the movable plate needs to bear a large gravity because the weight of the silicon steel sheet is often large, which will cause the movable plate to bear an unbalanced force. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figures 1 to 4 As shown, an embodiment of the present invention provides a core assembly platform, comprising:

[0049] A frame 100, the frame 100 includes a work surface 110 and a support structure 120 for supporting the work surface 110, the work surface 110 is provided with a through hole 111, the support structure 120 includes a first support 121, and the first support 121 is inclined relative to a horizontal plane;

[0050] A frame 210, wherein the frame 210 is disposed on the work surface 110, and the frame 210 has a receiving cavity. A first opening and a second opening are respectively provided at opposite ends of the frame 210, and the receiving cavity is communicated with the outside through the first opening and the second opening. The first opening is close to the through hole 111 and is communicated with the through hole 111;

[0051] A displacement driving mechanism, wherein the displacement driving mechanism is disposed below the work surface 110;

[0052] The movable plate 410 is connected to the movable end of the displacement driving mechanism. The movable plate 410 is tilted and its edge is in sliding contact with the first bracket 121. The movable plate 410 can be moved along the first bracket 121 under the drive of the displacement driving mechanism to approach or move away from the first opening.

[0053] As shown in the figure, the storage cavity in the frame 210 is used to place silicon steel sheets or iron cores composed of silicon steel sheets. The first opening and the second opening are respectively provided at opposite ends of the frame 210, so as to facilitate gluing multiple surfaces of the iron core through these openings, or to facilitate taking out the assembled iron core. When the silicon steel sheet is placed in the storage cavity, the movable plate 410 is driven by the displacement drive mechanism to approach the first opening, so as to support the silicon steel sheet.

[0054] The size and positional relationship between the movable plate 410 and the first opening can be adjusted according to actual needs. For example, in this embodiment, the movable plate 410 can move to contact the end of the frame 210 where the first opening is opened, and form a sealing effect on the first opening. In an optional embodiment, the movable plate 410 may not contact the frame 210 during the movement and adjustment stroke; in another optional embodiment, the movable plate 410 may not completely cover the first opening in the height direction projection. That is to say, in the above embodiment, when the movable plate 410 is supported, the silicon steel sheet can be completely closed at the first opening, or it can be exposed to the outside through the first opening, and it only needs to ensure that the silicon steel sheet does not fall.

[0055] When the core needs to be glued from the first opening, or the core needs to be taken out of the storage cavity, the movable plate 410 is driven by the displacement drive mechanism to move away from the first opening so that the first opening is fully exposed for subsequent operations.

[0056] The movable plate 410 is supported or guided by the first bracket 121 during the movement of approaching or moving away from the first opening. Considering that the movable plate 410 has to bear a large gravity when supporting the silicon steel sheet, the first bracket 121 plays a supporting role for the movable plate 410 at least when the movable plate 410 supports it. In this embodiment, the edge of the movable plate 410 is in contact with the first bracket 121 during the entire movement. In an optional embodiment, the edge of the movable plate 410 may also be in contact with the first bracket 121 only during a certain section of the movement close to the first opening.

[0057] The specific structure of the displacement driving mechanism can be selected according to actual needs. In this embodiment, the displacement driving mechanism can include at least one of a cylinder, a hydraulic cylinder, a linear motor, a screw, and a rack and pinion lifting mechanism.

[0058] In the embodiment of the present invention, the edge of the movable plate 410 is slidably contacted to the inclined first bracket 121, and the plate surface of the movable plate 410 is inclined accordingly. When the movable plate 410 supports the silicon steel sheet or the iron core, the force can be shared by the frame 210 and the first bracket 121, thereby improving the support strength and reducing the adverse effects of gravity or unbalanced force on the movable plate 410. At the same time, the first bracket 121 can also guide and support the movement process of the movable plate 410 approaching or moving away from the first opening, reducing the bending moment caused by the gravity of the movable plate 410 itself to the displacement drive mechanism, making the driving process smoother.

[0059] like Figure 2 , Figure 3As shown, in this embodiment, the above-mentioned work surface 110 is tilted relative to the horizontal plane; the tilt angle and tilt direction of the work surface 110 are the same as the tilt angle and tilt direction of the above-mentioned movable plate 410. The frame 210 is arranged on the above-mentioned work surface 110 and tilts accordingly with the work surface 110, so that the first opening is arranged relative to the through hole 111 on the work surface 110. The work surface 110, the movable plate 410, and the frame 210 are all at a certain angle to the horizontal plane. The advantage of this is that when the silicon steel sheet is placed in the accommodating cavity, due to the angle of the plate surface, it will be affected by the gravity of the silicon steel sheet itself, and it will be close to one side of the frame 210. The starting position is very clear, and the subsequent assembly operation of the iron core is simpler. Whether the work surface 110 is tilted, the tilt direction, and the tilt angle may not be limited. For example, in an optional embodiment, the work surface 110 may be horizontally arranged, and the frame 210 may be tilted on the work surface 110, and the tilt angle and direction are consistent with the movable plate 410, which can also achieve the effect of clearly defining the starting position of the silicon steel sheet.

[0060] The displacement drive mechanism can be Figure 3 The structure shown is installed, specifically, the above-mentioned support structure 120 also includes a second support 122, and the first support 121 and the second support 122 are arranged vertically; the fixed end of the displacement driving mechanism is arranged on the second support 122. In an optional embodiment, a mounting base plate 420 is provided on the second support 122, and the fixed end of the displacement driving structure is installed on the above-mentioned mounting base plate 420. Further preferably, the above-mentioned support structure 120 also includes a third support 123, and the second support 122 is installed on the third support 123; when the third support 123 is placed on the ground, it forms a support for structures such as the work surface 110 and the frame 210. In this embodiment, the displacement driving structure is integrated into the support structure 120, which is convenient for overall transportation and avoids repeated positioning between the movable plate 410 and the frame 210.

[0061] In an optional embodiment, a first sliding guide is provided on the first bracket 121; a second sliding guide matching the first sliding guide is provided on the edge of the movable plate 410; the first sliding guide is slidably connected to the second sliding guide. The structural form of the first sliding guide and the second sliding guide can be selected according to actual needs, for example, optionally, the first sliding guide is a guide groove, the second sliding guide is a guide protrusion or a roller, or the two types of sliding guides are located in opposite positions.

[0062] In another optional embodiment, the first bracket 121 is a square column; the movable plate 410 is provided with a limit piece at the edge of the first bracket 121 where it slides and contacts; the limit piece has a first limit surface and a second limit surface, and the first limit surface and the second limit surface are respectively abutted against two adjacent end surfaces of the square column. The embodiment of the present invention makes the connection between the first bracket 121 and the movable plate 410 more reliable through the above connection structure, which is conducive to improving the stability of the movement of the movable plate 410.

[0063] In this embodiment, the core assembly platform also includes a rotating connector 220; the frame 210 is rotatably connected to the work surface 110 through the rotating connector 220. When the movable plate 410 moves to the first opening, the frame 210 is tilted relative to the horizontal plane. In the process of processing the silicon steel sheet into the core, multiple surfaces need to be coated with glue. With the structure in this embodiment in which the frame 210 is rotatably connected to the work surface 110, glue can be first applied to one side of the core from the second opening located above, and then the frame 210 and the core can be turned over as a whole so that the first opening is turned to the top, and then glue is applied to the other side of the core. The operation is simple and can greatly improve the assembly efficiency.

[0064] The frame 210 is provided with a guide hole; the core assembly platform further includes: a clamping cylinder 300, the movable end of the clamping cylinder 300 extends into the accommodating cavity through the guide hole.

The multiple side plates constituting the frame 210 are preferably connected by welding. Of course, the above-mentioned connection method can be selected according to needs, such as screw connection. The clamping cylinder 300 can clamp the silicon steel sheet or the core onto a specific side plate of the frame 210, for example, see Figure 4 After the silicon steel sheet is placed in the accommodating cavity, the first cylinder 310 moves from right to left to press the silicon steel sheet and make it flat on the third side plate 213, and the second cylinder 320 moves from back to front to press the silicon steel sheet and make it flat on the fourth side plate 214. Through the joint action of the pressing cylinder 300 and the frame 210, the silicon steel sheet is pressed and flat, thereby improving the assembly quality of the iron core.

[0065] The number of the first cylinder 310 and the second cylinder 320 can be selected as required, for example, Figure 4As shown, in an optional embodiment, there is a first cylinder 310 and four second cylinders 320. The structure of the pressing cylinder 300 acting on the silicon steel sheet core can be the cylinder piston rod body or the pressing plate arranged at the end of the cylinder piston rod. For a structure with multiple cylinders on a single side plate, for example, multiple second cylinders 320 are arranged on the second side plate 212 at the same time, each second cylinder 320 can be configured with a pressing plate, or multiple second cylinders 320 can share a pressing plate.

[0066] Further, based on the above embodiment, Figure 2 , Figure 3 As shown, in this embodiment, the rotating connecting member 220 includes a bearing seat 221, a bearing 222 and a sleeve 223 which are nested and connected in sequence; the first side plate 211 and the third side plate 213 which are arranged opposite to each other are provided with sleeve holes; the sleeve 223 is fixedly connected to the sleeve hole in the circumferential direction. The second cylinder 310 is connected to the sleeve 223 corresponding to the first side plate 211, and the sleeve 223 is provided with an opening for the movable end of the second cylinder 310 to extend into the storage cavity, which actually forms the guide hole on the frame 210.
