Description

Technical Field

[0001] The invention relates to a flaring twist head assembly device, in particular to a flaring twist head assembly device for a flat wire motor stator hairpin end portion. Background Art

[0002] In the production process of flat wire motor stators, expansion and twisting are two essential process steps, which are also directly related to whether the subsequent process steps can proceed smoothly. First, the stator hairpin end is expanded according to the specified size, showing a layer-by-layer separation effect, and then it is twisted at a certain angle at the twisting station, so that the PIN feet at the stator end of the inserted PIN are staggered and twisted to achieve the ideal effect. At present, the domestic flat wire automated production line is that after the expansion process is completed, the robot takes the stator and flips it, and puts it on the assembly line tooling. When the twisting process comes, the robot takes the stator and puts it into the twisting station. In this way, the stator needs to be picked up and placed many times during the expansion and twisting process, which greatly increases the probability of damage to the stator end hairpin, and the stator with unqualified expansion cannot be reused, resulting in waste of resources, increased costs, and affecting the subsequent motor process, thereby affecting the motor quality.
