[0002] The slot insulation insertion device is a device that inserts slot insulation paper into the stator core according to a certain shape. The process of inserting slot insulation paper into the stator is an indispensable process in the production of motor stators. At present, the domestic flat wire motor O-slot insulation paper is still formed and inserted into the stator by manual paper insertion, that is, the stator is first manually fixed on the positioning tooling, and the insulation paper to be inserted is cut and folded to finally form it into an O shape, and then manually inserted into each insulation slot in turn. The problems with this type of paper insertion are: low efficiency, low degree of automation, poor O-type insulation paper forming effect, and the depth of the inserted insulation paper will be uneven due to the influence of manual operation, which will affect the subsequent motor process and thus affect the motor quality.
