Description

Technical Field

[0001] This invention relates to the field of motor stator assembly technology, and in particular to a stator modular assembly device. Background Technology

[0002] With the rapid development of new energy drive motors, industrial servo motors, and other fields, modular stators have been widely used in motor manufacturing due to their advantages such as high winding efficiency, high slot fill factor, and flexible adaptability to different pole numbers. The assembly of the stator modules requires the sequential completion of core processes such as modular assembly and overall cage insertion. The assembly accuracy, coaxiality, and production efficiency directly determine the motor's operating performance and manufacturing cost.

[0003] Currently, stator assembly in the industry mainly relies on semi-automatic methods with manual assistance and simple tooling. This method has the following technical defects: the rounding process depends on manual placement and positioning of each piece, resulting in poor roundness and uniformity of the gaps between pieces, low coaxiality accuracy, and product quality is significantly affected by the operator's skill level, making it difficult to guarantee consistency and failing to meet the assembly requirements of high-precision motors.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a stator segmentation and assembly equipment that integrates a material handling mechanism, a rounding mechanism, an ejection mechanism, a transfer mechanism, a cage-entry mechanism, and a unloading mechanism. It fully covers all processes of stator segmentation from material feeding, rounding, ejection and transfer, cage-entry pressing to finished product unloading. The entire process requires no manual intervention, significantly reducing labor intensity and effectively improving production cycle and capacity. At the same time, it eliminates quality fluctuations caused by manual operation, ensuring the assembly accuracy and consistency of batch products.

The translation mechanism is used to transfer the assembling mechanism to the ejection mechanism. The translation mechanism includes a first linear module, and the assembling mechanism is located on the output end of the first linear module. The first linear module drives the assembling mechanism to move laterally.

[0011] As a preferred embodiment, the ejection mechanism includes a downward pressing mechanism and an upward pressing mechanism arranged opposite to each other; the upward pressing mechanism is used to abut against the bottom of the multiple stator segmented circles, and the downward pressing mechanism is used to abut against the top of the multiple stator segmented circles, so that the upward pressing mechanism and the downward pressing mechanism together form an upper and lower clamping and fixing of the multiple stator segmented circles, so that the multiple stator segmented circles can be detached from the assembly mechanism; The upper lifting mechanism includes a second linear module, an upper lifting seat on the output end of the second linear module, and multiple upper lifting rods on the upper end of the upper lifting seat.

[0013] As a preferred embodiment, the cage-feeding mechanism includes an upper pressing mechanism and a lower lifting mechanism arranged opposite to each other. The lower lifting mechanism is used to abut against the bottom of the multiple stator segmented circles; the upper pressing mechanism is used to abut against the top of the multiple stator segmented circles and press the multiple stator segmented circles downward into the cage; the upper pressing mechanism and the lower lifting mechanism together form an upper and lower clamping and fixing of the multiple stator segmented circles, so that the multiple stator segmented circles can be detached from the transfer mechanism; A positioning mechanism for supporting the positioning cage is provided between the upper pressing mechanism and the lower lifting mechanism. The cage has a vertically penetrating receiving cavity, and the positioning mechanism has a vertically penetrating clearance channel. The axis of the receiving cavity of the cage coincides with the axis of the clearance channel. The lower lifting mechanism includes a seventh linear module, a lifting seat located on the output end of the seventh linear module, and a lifting assembly located on the upper end of the lifting seat. The lifting assembly can pass through the clearance channel and the receiving cavity.

[0014] As a preferred embodiment, a transfer mechanism is provided between the feeding mechanism and the cage-feeding mechanism.

The transfer cylinder drives the two transfer clamps to move closer to or further away from each other. The two transfer clamps together form a horizontal clamping and fixing of the cage of multiple stator segmented circular assemblies that have been caged on the cage-entering mechanism.

[0015] As a preferred embodiment, a detection mechanism is provided on one side of the assembly mechanism. The detection mechanism is used to detect whether the assembly of multiple stator blocks on the assembly mechanism is qualified. When the detection mechanism detects a failure, it will issue an alarm.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: This invention integrates a material handling mechanism, a rounding mechanism, an ejection mechanism, a transfer mechanism, a cage-entry mechanism, and a unloading mechanism, fully covering all processes of stator segmentation from material feeding, rounding, ejection and transfer, cage-entry pressing to finished product unloading. The entire process requires no manual intervention, significantly reducing labor intensity and effectively improving production cycle time and capacity. At the same time, it eliminates quality fluctuations caused by manual operation, ensuring the assembly accuracy and consistency of batch products.

[0017] The assembly mechanism of this invention adopts a radial transmission structure with a turntable linkage groove and a linkage wheel. Multiple sets of assembly components can be driven to move radially inward or outward synchronously through a single rotary drive unit. The multi-station action has strong synchronization and high accuracy in roundness and coaxiality. Combined with the linear guidance of the base plate slide groove for the slide rail, the operation is smooth and without sway.

[0018] The ejection mechanism of this invention adopts an upper ejection mechanism and a lower pressing mechanism for opposing clamping. During ejection, the pushing step of the upper ejector rod abuts against the bottom outer side of the stator segment, and the annular pressing step of the lower pressing cover abuts against the top outer side of the stator segment. The upper and lower parts together hold and fix the entire stator assembly, so that the workpiece always maintains an overall constrained state during the process of detaching from the assembly mechanism, fundamentally avoiding the problems of segment disintegration and misalignment. Moreover, the pressing and pushing parts act on the stator core structure surface and will not touch the winding and insulation components, effectively preventing workpiece damage and ensuring a stable and reliable ejection process.

[0019] The cage-feeding mechanism of this invention adopts a pressing mode with an upper pressing mechanism and a lower lifting mechanism working in tandem. The positioning mechanism can accurately position the cage body to ensure the coaxiality of the cage body and the stator assembly. The multiple lifting blocks of the lower lifting mechanism are floatingly installed through elastic reset parts, which has a flexible buffering effect during the cage-feeding pressing process. This can avoid rigid hard contact causing scratches and damage to the stator core, insulation layer and windings, while making the force on each block more uniform. The pressing process is smooth and without jamming, and the lifting blocks can float up and down. In conjunction with the annular pressing part of the upper pressing mechanism, which abuts against the top of the outer side of the multiple stator assembly, the lower surface of the multiple stator assemblies can float downward when the upper pressing mechanism presses the multiple stator assemblies into the cage. This eliminates the phenomenon that the upper and lower surfaces of the assembled stator core are uneven due to the inability to achieve absolute consistency in the tolerance of the stacked iron sheets between different stator assemblies. This ensures that at least the upper surface of the multiple stator assemblies is flat.

The abutment surface 244 has a contact block 245 that is detachably locked by screws. The contact block 245 has an arc-shaped contact surface 2451 that abuts against the outside of the stator segment 1.

The third linear module 311 drives the pressing seat 312 to move up and down, and the pressing seat 312 drives the pressing cover 313 to move up and down. The third linear module 311 can be a motor-driven linear module, as long as it can drive the pressing seat 312 to move up and down linearly. It will not be described in detail here.

[0045] A detection mechanism 80 is provided on one side of the rounding mechanism 20. The detection mechanism 80 is used to detect whether the rounding of multiple stator blocks on the rounding mechanism 20 is qualified. When the detection mechanism 80 detects a failure, it will issue an alarm. The detection mechanism 80 detects whether the number of stator blocks 1 on the rounding mechanism 20 is qualified and whether the stator blocks are skewed, etc. The detection mechanism 80 is installed on the pressing mechanism 31 and located next to the third linear module 311. The detection mechanism 80 is a detection camera.

[0046] An inspection mechanism 80 is set up next to the rounding mechanism 20, which can perform online quality inspection on the completed stator segmented components. If the components are not qualified, an alarm will be issued in time. Defective products can be intercepted in the rounding process, preventing them from flowing into subsequent processes such as cage loading, effectively reducing rework costs and material losses, and improving the overall production yield.

[0047] The transfer mechanism 40 is used to pick up and deliver multiple stator segments ejected by the ejection mechanism 30; the transfer mechanism 40 includes a fourth linear module 41, a fifth linear module 42 disposed on the output end of the fourth linear module 41, a sixth linear module 43 disposed on the output end of the fifth linear module 42, a transfer cylinder 44 disposed on the output end of the sixth linear module 43, and two transfer clamps 45 connected to the transfer cylinder 44. The fourth linear module 41 drives the fifth linear module 42 to move back and forth along the X direction. The fifth linear module 42 drives the sixth linear module 43 to move back and forth along the Y direction, and the sixth linear module 43 drives the transfer cylinder 44 to move back and forth along the Z direction. The transfer cylinder 44 drives the two transfer clamps 45 to move closer or further away from each other. The two transfer clamps 45 together form a horizontal clamping and fixing of the multiple stator segmented circles ejected by the ejection mechanism 30. The two transfer clamps 45 each have a semi-circular clamping groove, and the semi-circular clamping grooves of the two transfer clamps 45 respectively clamp the outer side of the multiple stator segmented circles.

[0048] The transfer mechanism 40 adopts a configuration of X, Y, and Z three-axis linear modules combined with pneumatic grippers, which has the ability to freely transfer in three-dimensional space.

The cage-feeding mechanism 50 also includes a U-shaped mounting frame 53. The upper pressing mechanism 51 and the lower lifting mechanism 52 are respectively installed on the upper and lower sides of the mounting frame 53. The lower lifting mechanism 52 is used to abut against the bottom of multiple stator segmented circles. The upper pressing mechanism 51 is used to abut against the top of multiple stator segmented circles and press the multiple stator segmented circles downward into the cage 2. The upper pressing mechanism 51 and the lower lifting mechanism 52 together form an upper and lower clamping and fixing of multiple stator segmented circles, so that the multiple stator segmented circles can be detached from the transfer mechanism 40.

The cage 2 has a vertically penetrating receiving cavity 201, and the positioning mechanism has a vertically penetrating clearance channel 552.

[0055] The seventh linear module 521 drives the lifting seat 522 to move up and down, and the lifting seat 522 drives the lifting component 523 to move up and down, so that multiple lifting blocks 5231 simultaneously pass upward through the receiving cavity 201 of the cage 2 and extend out of the upper end of the cage 2 or retract downward.

[0057] The lifting block 5231, combined with the sliding groove 5237 guide structure, ensures precise up-and-down movement without deviation, further improving the cage entry accuracy and finished product yield.

The eighth linear module 511 drives the pressing seat 512 to move up and down, and the pressing seat 512 drives the pressing cover 513 to move up and down.

[0060] The lifting seat 522 and the pressing seat 512 are respectively connected to the U-shaped mounting frame 53 through the guide structure of the guide column and guide sleeve.

[0061] Both the seventh linear module 521 and the eighth linear module 511 can adopt a transmission structure of motor and lead screw. It is only necessary to ensure that the seventh linear module 521 can drive the lifting seat 522 to move up and down linearly and the eighth linear module 511 can drive the pressing seat 512 to move up and down linearly. This will not be elaborated here.
