Description

Technical Field

[0001] This invention relates to the field of electric motors, and in particular to a stator screw receiving, pushing and rotating feeding device and a stator screw assembly machine for electric motors. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy, its core function being to drive a load to rotate or move linearly. Its core components include a stationary stator, a rotating rotor, and control circuitry, achieving energy conversion through the principle of electromagnetic induction. As a medium providing rotational power, electric motors have a wide range of applications, such as in electric vehicle drives, robot joint drives, fans, and vibrators.

[0003] The motor stator is the core component of a motor, and it has two main functions: generating a rotating magnetic field and providing mechanical support. Specifically, generating a rotating magnetic field: when three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated, which is crucial for the motor's rotation. Mechanical support and fixation: the stator frame is responsible for fixing and supporting the entire stator core and windings, ensuring the stability of the motor structure. During the manufacturing process of the motor stator, screw and spring assemblies need to be inserted at the four corners of the stator base. This involves first inserting the screw into the spring from above, with the lower end of the screw protruding from the spring to form a screw-spring assembly, and then inserting the screw-spring assembly as a whole into the screw holes at the four corners of the stator base. Based on the above assembly process, the production assembly process involves the combination of four screws and four springs, as well as the insertion of four sets of screw and spring assemblies. In order to improve efficiency during the automated design and assembly of stator screws, four screw and spring assemblies are assembled onto the stator simultaneously in one go. Therefore, it is necessary to solve the problem of automatic transfer and guiding of screw and spring assemblies. In view of this, it is necessary to design a motor stator screw receiving, pushing and rotating feeding device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a motor stator screw receiving, pushing and rotating feeding device and stator screw assembly machine that adopts dual-channel synchronous feeding, realizes rotary alternating multi-material feeding, and has limit and guide functions, thereby achieving efficient transfer feeding and improving the feeding position accuracy of screw and spring assembly.

[0010] Preferably, the limiting ring includes two rings with an arc-shaped structure. The two limiting rings are symmetrically arranged on the outside of the turntable, forming a circular structure with a central circular slot. The turntable is located inside the circular slot, and the circular structure formed by the limiting rings covers the outer edge to block the screw and spring assembly in the material groove. The two ends of the limiting rings are connected to the guide seat, and a gap is left at the connection point so that the guide seat can guide the screw and spring assembly into the material groove through the gap.

[0013] A stator screw assembly machine including a stator screw receiving, pushing and rotating feeding device.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a motor stator screw receiving, pushing, and rotating feeding device and its stator screw assembly machine. This device employs dual-channel synchronous feeding, while simultaneously achieving rotary alternating multi-material feeding and featuring limit and guidance functions. It achieves efficient transfer feeding while improving the feeding position accuracy of screw and spring assemblies.

[0016] This invention relates to the automated assembly process of screws for motor stators and is a core structure in an automated motor screw assembly production line. Its function is to provide a transfer and feeding mechanism for screw and spring assemblies during the motor stator screw assembly process, as well as a multi-material discharge mechanism, so that the assembly robot can remove them and assemble them onto the stator. The automated motor screw assembly production line involves the automatic supply of three materials: stator, screws, and springs. The stator is typically placed on a stator carrier and then fed along the production line by the carrier. Screws and springs are discharged separately through a guiding mechanism, assembled into screw and spring assemblies, and then discharged near the stator carrier for the robot to remove and insert into the stator. The invention comprises a central transfer platform and pushing components on both sides of the transfer platform. A rotary motor is mounted on the base of the transfer platform, outputting rotational power in a horizontal plane to drive a vertically mounted rotating column to rotate. The rotating column drives the turntable on top of it to rotate. The turntable is a circular platform with multiple material slots spaced along its circumference. The outer side and top of the material slots are open for inserting screw and spring assemblies, and the bottom of the material slots is open to allow the bottom of the screw to pass through. A key feature is that guide seats are provided on both sides of the turntable, and each guide seat contains a transfer groove with an L-shaped cross-section. The discharge port of the transfer trough connects to the material trough, and the inlet connects to the outer discharge assembly. The screw and spring assembly pushed out by the discharge assembly enters the transfer trough. After the screw and spring assembly enters the transfer trough, it is inverted and wrapped by the U-shaped pusher block of the pusher component from above, and then it is transferred from the transfer trough into the material trough of the turntable, realizing the transfer and distribution of screw and spring assemblies. During the distribution process, the guide seats on both sides of the turntable synchronously guide the screw and spring assembly from both sides into the material trough of the turntable. After the guide is completed, the turntable rotates one unit angle and switches to the next empty material trough to connect with the transfer trough of the guide seat. This cycle is repeated to realize the synchronous transfer and feeding of materials through dual channels. Furthermore, the rotary motor of the present invention is provided with an outer support horizontally above it. The rotating column passes through the outer support from bottom to top and rotates freely within the outer support to avoid motion interference. The outer support extends horizontally to both sides of the turntable to support the guide seats on both sides of the turntable. At the same time, multiple support rods are provided at intervals along the outer side of the turntable on the outer support. Two symmetrically arranged limiting rings are provided at the top of the support rods. The joint of the two limiting rings corresponds to the discharge port of the guide seat and leaves a gap so that the screw and spring assembly in the rotating groove of the guide seat can enter the material groove of the turntable. The limiting rings limit the turntable from the outside to prevent the screw and spring assembly from sliding out of the material groove during the rotation of the turntable.
