Description

Technical Field

[0001] This utility model relates to the field of lamination mechanism technology, and in particular to a lamination mechanism and production equipment for motor lamination. Background Technology

[0002] With the rapid development of the new energy vehicle industry and increasingly fierce market competition, the performance requirements for automotive drive motors are becoming more and more stringent. High efficiency, high power, and high speed have become important directions in drive motor design, and the improvement of these performances largely depends on the selection and optimization of motor materials. As the main material for the motor core, silicon steel sheets have a decisive influence on the overall performance of the motor.

[0003] In recent years, to meet the demands of improved motor performance, the trend in silicon steel sheet usage has gradually shifted towards thinner, higher-strength materials. Traditional silicon steel sheets are typically 0.5mm thick, but with technological advancements, they have transitioned to ultra-thin specifications of 0.35mm, 0.27mm, 0.2mm, 0.15mm, and even 0.10mm. Furthermore, some leading companies have begun experimenting with using amorphous materials to produce motor cores, further enhancing motor efficiency and performance. However, the use of these high-performance materials has also brought new challenges. While amorphous materials and ultra-thin silicon steel sheets possess superior performance, their brittleness makes them difficult to secure using traditional mechanical fastening methods. Therefore, during production, these materials can only be produced through sheet stamping and stacking outside the mold. Due to the thinness of individual sheets, stacking cores of the same height requires more time and manpower than with ordinary silicon steel sheets, leading to low production efficiency and increased costs.

[0004] Therefore, there is an urgent need for a mechanism that can automatically, efficiently, and stably sort and stack motor laminations to solve the existing problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a lamination sorting mechanism and a lamination production equipment for motors. By using mechanization, it achieves automatic lamination sorting and stacking of motor laminations, realizing the purpose of whole-stack output, thereby improving production efficiency, reducing costs, and meeting the demand for high-performance materials in drive motors for new energy vehicles.

[0006] The present invention adopts the following technical solution:

[0007] This utility model provides a sheet handling mechanism for motor laminations, which is mounted on a machine base and is suitable for stacking motor laminations. It includes: a receiving turntable rotatably mounted on the machine base and having a through hole for sheet drop; a plurality of receiving units spaced circumferentially inside the through hole of the receiving turntable, the receiving units being configured to move radially along the receiving turntable to switch between at least an extended state and a retracted state, thereby supporting or releasing the stacked sheets; and a drive source adapted to drive the receiving turntable to rotate.

[0008] The receiving turntable is configured such that when it rotates along a first direction, it can drive the receiving unit to switch to and remain in the extended state in order to support the stacked sheets; and when it rotates along a second direction opposite to the first direction, it can drive the receiving unit to switch from the extended state to the retracted state in order to release the stacked sheets.

[0009] Furthermore, the inner wall of the receiving turntable is provided with multiple retaining surfaces to keep the multiple receiving units in the extended state.

[0010] Furthermore, the inner side of the receiving turntable is provided with a plurality of recesses that are recessed relative to the holding surface, so that the plurality of receiving units can be switched to the retracted state.

[0011] Furthermore, the recessed portion is an arc-shaped groove with its opening facing the receiving unit, and the end of the receiving unit is an arc-shaped head that is adapted to the arc-shaped groove.

[0012] Furthermore, the receiving unit includes a fixed base disposed inside the receiving turntable; a receiving rod slidably disposed on the fixed base; and a force-applying member configured to apply force to the receiving rod in a direction that causes the receiving rod to abut against one side of the receiving turntable.

[0013] Furthermore, the inner surface of the fixing seat is formed as an arc surface, and a channel for the sheet to fall is defined between the plurality of fixing seats.

[0014] Furthermore, the force-applying component is configured as any one of a magnetic component, an elastic component, or an adsorption component.

[0015] Furthermore, the driving source is a cylinder, wherein the cylinder is configured to drive the receiving turntable to reciprocate within a set time period to control the number of sheets stacked.

[0016] Furthermore, it also includes a push rod, through which the drive source drives the receiving turntable to rotate.

[0017] This utility model also provides a production equipment for motor lamination, comprising: a mold mechanism adapted to perform lamination processing; a lamination sorting mechanism adapted to stack and sort the laminations falling from the mold mechanism; and a conveying mechanism disposed below the lamination sorting mechanism to convey the stacked laminations out; wherein the lamination sorting mechanism is the aforementioned lamination sorting mechanism for motor lamination.

[0018] By adopting the above technical solution, this utility model has the following technical effects:

[0019] The lamination handling mechanism for motors disclosed in this application is ingeniously designed and highly functional, suitable for stacking motor laminations. Through the coordinated action of the receiving turntable, receiving unit, and drive source, it achieves automatic support and release of the laminations, further improving production efficiency. Specifically, the receiving turntable is designed to drive the receiving unit to switch between extended and retracted states according to different rotation directions, thereby achieving support and release of the stacked laminations. This design not only simplifies the operation process but also improves the accuracy and stability of lamination handling.

[0020] By setting up a sheet handling mechanism below the blanking station, which includes the function of stacking and outputting unriveted stampings, the subsequent sheet handling time is significantly reduced, production efficiency is greatly improved, and production costs are effectively reduced. Moreover, this application optimizes this process through mechanization, ensuring the stability and efficiency of materials during processing. Attached Figure Description

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0034] Please see Figures 1 to 6 As shown, this utility model provides a lamination handling mechanism 200 for motor laminations, which is mounted on a machine base 400 for stacking motor laminations. The mechanism includes a receiving turntable 210, multiple receiving units 220, and a drive source. The receiving turntable 210 is rotatably mounted on the machine base 400 and has a through hole 213 for the laminations 300 to fall through. Multiple receiving units 220 are circumferentially arranged inside the through hole 213 of the receiving turntable 210, and each receiving unit 220 is configured to move radially along the receiving turntable 210 to switch between at least an extended state and a retracted state, thereby supporting or releasing the stacked laminations 300. The drive source is adapted to drive the receiving turntable 210 to rotate, thereby controlling the movement of the receiving units 220. Specifically, when the receiving turntable 210 is configured to rotate around an axis in a first direction A, it can drive the receiving unit 220 to switch to and remain in the extended state to support the stacked sheets 300; when it rotates in a second direction B opposite to the first direction A, it can drive the receiving unit 220 to switch from the extended state to the retracted state to release the stacked sheets 300. When multiple receiving units 220 retract simultaneously, a channel is defined in the middle for the sheets 300 to fall, so that the stacked sheets 300 fall through the channel, thereby controlling the number of blanking sheets, achieving the purpose of whole-stack output, satisfying the requirement of whole-stack output for blanking sheets that cannot be riveted, reducing the subsequent sheet handling time, improving production efficiency, and reducing production costs. It should be noted that in this embodiment, the sheet 300 includes iron chips or ultra-thin silicon steel sheets made of amorphous materials. The thickness of the ultra-thin silicon steel sheets is less than 0.4mm, such as 0.35mm, 0.27mm, 0.2mm, 0.15mm or even 0.10mm.

[0035] In this embodiment, the inner side of the receiving turntable 210 is provided with a plurality of retaining surfaces 211 and a plurality of recesses 212 that are recessed relative to the retaining surfaces 211. The plurality of recesses 212 and the plurality of retaining surfaces 211 are spaced apart from each other to simultaneously control the extension and retraction of the plurality of receiving units 220. The recesses 212 are configured as arc-shaped grooves with their openings facing the receiving unit 220. The end of the receiving unit 220 is configured as an arc-shaped head that matches the arc-shaped groove, so that the receiving unit 220 can freely switch between the extended state and the retracted state. This design not only improves the reliability of the mechanism but also makes it more adaptable to the processing needs of sheets 300 of different specifications and materials. When it is necessary to stack the motor laminations, the end of the receiving unit 220 abuts against the inner side of the receiving turntable 210 so that the receiving units 220 are all in the extended state, thereby jointly defining a support structure for supporting the sheets 300. When the stacked sheets 300 reach a set number, the receiving turntable 210 rotates along the second direction B, so that the end of the receiving unit 220 is inserted into the groove. At this time, the receiving unit 220 is in the retracted state, thereby outputting the stacked sheets 300 in a whole stack.

[0036] In this embodiment, the number of receiving units 220 can be multiple, such as 3, 4, 6, 8, etc., and can be flexibly designed according to design requirements. This embodiment is not limited to this. Figure 3 As shown, the receiving unit 220 includes a fixed base 221 disposed inside the receiving turntable 210; a receiving rod 223 slidably disposed on the fixed base 221; and a force-applying member configured to apply force to the receiving rod 223 in a direction that abuts against one side of the receiving turntable 210, thereby allowing the end of the receiving unit 220 to abut against the receiving turntable 210, and thus move between the holding surface 211 and the groove as the receiving turntable 210 rotates; preferably, the force-applying member is any one of a magnetic element, an elastic element, or an adsorption element. In this embodiment, the force-applying member is a spring 222. Meanwhile, in order to enable the stacked sheets 300 to fall more effectively, the inner side of the fixing seat 221 is formed as an arc surface, and the fixing seats 221 define a channel for the sheets 300 to fall. The configuration of the fixing seat 221, spring 222, receiving rod 223 and other components enhances the stability and durability of the mechanism. The design of the fixing seat 221 allows the receiving rod 223 to slide stably, while the spring 222 ensures that the receiving rod 223 can quickly reset when subjected to external force, thereby ensuring the continuity and stability of the mechanism.

[0037] Furthermore, the drive source is configured as a cylinder 24, wherein the cylinder 24 is configured to drive the receiving turntable 210 to reciprocate within a set time period to control the number of sheets 300 stacked; further, a push rod 23 is also included, through which the drive source drives the receiving turntable 210 to rotate. By configuring the cylinder 24 as the drive source, precise control of the number of sheets 300 stacked is achieved; the cylinder 24 can drive the receiving turntable 210 to reciprocate within a set time period, thereby achieving precise stacking and output of the number of sheets 300. This design not only improves production efficiency but also ensures the stability and consistency of product quality; of course, in other embodiments, the drive source can also be an electric push rod, a hydraulic push rod, etc., any mechanism capable of driving the receiving turntable 210 to rotate. In addition, a controller is also included, which can be a PLC controller, a microcontroller, etc., to achieve automated control of the cylinder 24.

[0038] See Figures 1 to 6 As shown, this utility model also provides a production equipment for motor lamination, including a mold mechanism 100, which is suitable for lamination processing; a lamination sorting mechanism 200, which is suitable for stacking and sorting the laminations 300 dropped from the mold mechanism 100; and a conveying mechanism, which is arranged below the lamination sorting mechanism 200 to convey the stacked laminations 300 out; wherein, the lamination sorting mechanism 200 adopts the above-mentioned lamination sorting mechanism 200 for motor lamination. By adopting the above scheme, the lamination sorting mechanism 200 is set below the blanking station where the mold mechanism 100 is located. In use, the cylinder 24 pushes the push rod 23, the push rod 23 drives the receiving turntable 210, the receiving turntable 210 pushes out the receiving rod 223 to receive the material, and vice versa, the receiving rod 223 retracts, which plays a counting role, controls the number of blanked laminations, and achieves the purpose of whole stack output. It should be noted that the mold mechanism 100 adopts the mold mechanism 100 used for motor core lamination in the prior art, and the conveying mechanism (not shown in the figure) can adopt the belt conveying mechanism of the prior art, which can flexibly support and convey stator laminations made of amorphous materials or ultra-thin silicon steel sheets.

[0039] In summary, the lamination handling mechanism 200 of this embodiment has multiple beneficial effects, such as significantly improving production efficiency, reducing production costs, and enhancing the stability and durability of the mechanism. It is particularly suitable for handling and stacking high-performance but brittle motor lamination materials.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
