Background
The stator core is an important part of a motor, and has a plurality of technical requirements on the core, wherein the inner diameter width of a lamination of the segmental punching sheet after lamination is required to meet the requirement of an air gap between a stator and a rotor, and the width of a wire embedding groove is required to meet the requirement of a drawing design. When the fan-shaped stator punching sheets are laminated, a stator lamination tool is usually used for assisting the lamination, a positioning mechanism in the middle of the stator lamination tool is provided with a groove sample bar for positioning the fan-shaped punching sheets, each punching sheet corresponds to one groove sample bar, the size of the groove sample bar is smaller than the groove size of the punching sheet, and the general groove sample bar is 10-15 wires smaller than a wire embedding groove so that the groove sample bar can be inserted into the wire embedding groove to position the punching sheet.
The stator lamination tooling generally comprises a stator support platform, a positioning mechanism and a slot sample rod, wherein the positioning mechanism is cylindrical and is positioned in the center of the stator support platform. In the prior art, the slot sample bars are inserted into the wire inserting slots of the stator core as independent positioning pieces and are generally arranged in a whole or end-to-end manner from bottom to top. In the lamination, the punching sheet is inserted from the side or placed from the top to the bottom.
The application number is CN202111244506.3, the name is a rotary lamination device and a lamination method suitable for a fan-shaped punching motor, and the rotary lamination device suitable for the fan-shaped punching motor comprises a rotary device and a lamination platform in transmission connection with the rotary device; the stacking platform comprises a circular stacking platform plate and a positioning device arranged on the stacking platform plate. The invention also discloses a lamination method of the rotary lamination device, which reduces the labor intensity of an operator, improves the working environment of the operator, ensures that the punching sheet is not influenced by the chord distance and the inner diameter size of the positioning ribs during lamination, and improves the lamination quality and the working efficiency. In this patent, every towards the piece corresponding a groove appearance stick to groove appearance stick is from supreme setting down. Each punching sheet corresponds to a groove sample rod, the groove sample rods are arranged from bottom to top, the punching sheets are placed from top to bottom, the punching sheet stroke is long (namely the lamination matching stroke), and the punching sheets are easy to be damaged by collision and scraping; in order to solve the problem, in the prior art, the punching sheet is inserted from the side surface, so that the technical problem that the punching sheet is easy to damage due to collision and scratch due to long stroke can be solved. On the other hand, the silicon steel sheet is very thin, only 0.5mm or even thinner, and a groove-shaped bar is used for positioning, so that the stamped sheet can rotate in the lamination process, namely, dislocation is inevitable in the lamination process, and the positioning is inaccurate; the damaged punching sheet and the inaccurate positioning of the punching sheet can cause the inner diameter of the lamination and the width of the embedded slot not to meet the requirement of an air gap between a stator and a rotor or the requirement of a drawing, and the performance of the motor is seriously influenced.
The following papers relate to channel bars:
(1) the des paper, slot bar size discussion, proposes that stator cores are important components of motors, and one of many technical requirements for cores is to ensure that the slots are orderly and meet the requirements. The paper describes the effect of slot bar size on the stator core, but does not address the issues of punch positioning, punch damage affecting the lamination inside diameter and the slot width.
(2) The 'Fujianning pumped storage power station motor generator stator core installation shallow analysis' paper of Zhongyutong proposes a stator core stacking method, when the iron core lamination is stacked to about 30mm of height, three slot sample bars and three slot wedge slot sample bars are placed on each punching sheet, and the slot sample bars are opposite to positioning ribs. The groove sample rod and the groove wedge groove sample rod are 100mm higher than the stacked iron core punching sheet. In the thesis, although three groove sample bars are correspondingly placed on each punching sheet, the groove sample bars are a common method of the lamination process, and the more the groove sample bars corresponding to each punching sheet are, the more accurate the positioning is, but the lamination difficulty is increased. In the thesis, the slot sample rod is independent, and after the punching sheet is placed, the slot sample rod is inserted into the slot for shaping and positioning the wire embedding slot. The groove sample rods are too many, the fan-shaped punching sheet can not be inserted from the side surface, and the punching sheet is placed from top to bottom and is easy to be damaged by collision and scraping. The thesis solves the problem of positioning, but does not solve the technical problems of long stroke and easy damage of punching sheets, and is difficult to realize automatic lamination.
The lamination tool in the prior art solves the problem of long lamination matching stroke and does not solve the positioning problem; or the problem of positioning is solved, and the problem of long lamination matching stroke is not solved. Because of the problems, in the lamination process, in the prior art, after the lamination is stacked to a certain height, the intervention such as the width measurement of the wire embedding groove, the inner diameter shaping and the like is required. In conclusion, the prior art cannot ensure good wire embedding groove width and lamination inner diameter, and is more difficult to realize full-automatic lamination.

The method for automatically stacking sector punching sheets according to claim 8, wherein a mechanical arm exerts a force on a yoke portion of a punching sheet after the punching sheet is placed, so that a tooth portion of the punching sheet is close to a positioning mechanism, and the inner diameter of the stacking sheet is shaped, so that the inner diameter of the stacking sheet is ensured to meet the design requirement.
10. The method for automatically laminating the segmental punches according to claim 8, wherein in the lamination process, the visual positioning system guides the control system to control the manipulator to accurately position the punches by identifying the positions of the visual positioning mark points.
