An assembly method, characterized in that: Using the assembly structure according to claim 9, the assembly method comprises: Step S1: the push rod pushes the plurality of magnets after dispensing into the first accommodating cavity through the magnet inlet of the positioning box, and the inner wall of the first accommodating cavity and the push rod are used to perform lateral positioning, and the pressing plate cooperates with the supporting plate to perform longitudinal positioning on the plurality of magnets, so that the plurality of magnets in the first accommodating cavity are linearly arranged and positioned; Step S2: Push the shaping box to the top of the positioning box, the pressing cylinder in the box pressing mechanism drives the pressing head to move downward, and presses and holds the positioned magnets, and limits the magnets longitudinally, and the positioning driving member drives the pressing plate to disengage from the longitudinal limit of the magnets until the pressing plate is retracted into the plate slot; Step S3: the pressing box driving member drives the pressing claw to press down the shaping box, and transforms the plurality of magnets in the first accommodating chamber into the lower chamber, and the pressing head always limits the plurality of magnets longitudinally until the plurality of magnets are longitudinally limited with the top of the lower chamber, and then the driving cylinder drives the pressing head to disengage, and the inner wall of the lower chamber limits the plurality of magnets laterally; Step S4: the sheet pushing mechanism pushes the fixing sheet to the top of the plurality of limiting assemblies, and the sheet pressing cylinder drives the pressing head to press down the fixing sheet and retract the plurality of limiting assemblies so that the fixing sheet is bonded and fixed to the plurality of magnets, thereby completing the assembly of the Halbach magnetic assembly in the molding box.
