[0003] In the related art, glue is first applied to the inner side of the outer rotor housing, and then the staff uses tools to stick the magnet to the inner side of the outer rotor housing, which results in low processing efficiency. In some related arts, related automated equipment is used to apply glue to the inner wall of the outer rotor housing, and then the magnet is clamped and pushed in along the axial direction of the outer rotor housing, so that the magnet is stuck to the inner side of the outer rotor housing, realizing automated processing.

[0004] However, in the process of pushing the magnet in along the axial direction of the outer rotor housing, the magnet and the inner wall of the outer rotor housing slide relative to each other, and the magnet is likely to scrape out a portion of the glue on the inner wall of the outer rotor housing, resulting in uneven distribution of glue on the inner wall of the outer rotor housing, making the adhesion between the magnet and the inner wall of the outer rotor housing fail to meet the requirements, affecting production quality.

The device for bonding and curing magnetic steel of an industrial fan outer rotor motor according to claim 7, characterized in that: The feeding assembly (6) further comprises a pushing ring (67) and a guide ring (68), wherein the guide ring (68) is connected to the feeding plate (61), and the guide ring (68) is provided with a material guide groove (681), and the feeding drive source (64) is capable of pushing the magnetic steel into the material guide groove (681); The ejection ring (67) is connected to a plurality of the ejection blocks (65), and the ejection drive source (66) is capable of inserting the ejection blocks (65) into the material guide groove (681), so that the ejection blocks (65) eject the magnetic steel located in the material guide groove (681) onto the material taking head (46).

9. The device for bonding and curing magnetic steel of an industrial fan outer rotor motor according to claim 1, characterized in that: The clamping assembly (2) comprises a chuck (21) and a rotation drive source (22), wherein the rotation drive source (22) is arranged on the supporting cabinet (1), the chuck (21) is connected to the rotation drive source (22), the rotation drive source (22) drives the chuck (21) to rotate, and the chuck (21) clamps the outer rotor housing; A glue coating component (3) is provided on the support cabinet (1), and the glue coating component (3) comprises a movable slide (32) and a glue coating head (31), the glue coating head (31) being connected to the movable slide (32), and the movable slide (32) drives the glue coating head (31) to coat glue on the inner wall of the outer rotor housing located on the chuck (21).

10. A method for bonding and curing the magnetic steel of an industrial fan outer rotor motor, characterized in that: The use of the industrial fan outer rotor motor magnetic steel bonding and curing device as described in any one of claims 1 to 9 comprises the following steps: S1: clamping the outer rotor housing onto the clamping assembly (2), and moving the slide (32) to drive the glue coating head (31) to move, so that the glue coating head (31) coats glue on the inner wall of the outer rotor housing; S2: starting the feeding drive source (64) and the ejecting drive source (66) so that the magnetic steel is located on the material taking head (46); S3: starting the lifting drive source (42) so that the material taking head (46) extends into the outer rotor housing, and the telescopic rod (45) pushes the material taking head (46) to move, so that the material taking head (46) adheres the magnetic steel to the inner wall of the outer rotor housing; S4: starting the pressing driving source (53) so that the pressing block (52) presses the top of the magnetic steel. At this time, the material taking head (46) releases the adsorption of the magnetic steel, and the lifting driving source (42) drives the supporting plate (44) to rise, so that the magnetic steel is separated from the guide groove body (47); S5: Remove the outer rotor housing from the clamping assembly (2).
