Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly equipment, and particularly relates to a rotary disk device for turning a brushless motor magnetic strip into a circular shape and inserting it into a motor housing. Background Art

[0002] The magnetic strip in a brushless motor is a crucial component, which is mainly responsible for providing the constant magnetic field required by the motor. This magnetic field is crucial for the normal operation of the motor because it affects the efficiency and performance of the motor. The magnetic strip is usually made of soft magnetic materials, such as iron powder pressed strips or other similar magnetic materials, which can effectively guide and enhance the magnetic field inside the motor.

[0003] When installing the magnetic strip, it needs to be wound into the motor housing and closely attached to the inner wall of the housing. The magnetic strip winding machine is a special assembly mechanism for replacing ferrite magnetic rings with rubber magnetic strips. However, when the existing magnetic strip winding mechanism processes the magnetic strip, it usually easily causes the magnetic strip to be extruded and deformed, the processing speed is slow, the processing efficiency is low, and at the same time, burrs are easily generated. When the existing magnetic strip winding mechanism transports the motor housing, it is usually manually transported, which not only increases the workload of the personnel, but also easily causes the motor housing to be placed unstably, affecting the installation effect.

[0004] For example, the Chinese invention application with the application number 202111492173.6 (authorization publication number CN117147447A) discloses a device for automatically winding a rubber magnetic strip into the inner wall of a circular housing; belonging to the technical field of magnetic strip forming and assembling; including a base, a bracket is arranged on the base, and a magnetic strip rounding member is arranged on the bracket. A magnetic strip conveying mechanism is arranged on the bracket on the side of the magnetic strip rounding member, and the long magnetic strip is sent into the magnetic strip rounding member through the magnetic strip conveying mechanism and wound into a circular ring; a housing conveying mechanism is arranged on the base below the magnetic strip rounding member, and a first pressing mechanism is arranged on the bracket above the magnetic strip rounding member. The housing conveying mechanism transports the housing to directly below the magnetic strip rounding member, and the formed magnetic strip in the magnetic strip rounding member is pressed into the inner wall of the housing through the first pressing mechanism. Although this application provides a device for automatically winding a rubber magnetic strip into the inner wall of a circular housing, it still requires manual transfer of the magnetic strip into the conveying mechanism. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a rotary disk device for turning a brushless motor magnetic strip into a circular shape and inserting it into a motor housing without manual placement of the magnetic strip in view of the above technical status.

[0016] In order to enable the first driving mechanism to push a single magnetic strip onto the guiding block, preferably, the side wall of the feeding groove extends inwards to form a blocking portion, and a discharging gap for a single magnetic strip to discharge is formed between the blocking portion and the guiding block. When the first driving mechanism pushes the magnetic strip, except for the lowermost magnetic strip in the feeding groove, the other magnetic strips are blocked by the blocking portion, so that the magnetic strips are still accommodated in the feeding groove.
