Description

Technical Field

[0001] The utility model relates to the technical field of iron core manufacturing, and in particular to a segmented iron core rotating collection, shaping and riveting system based on visual recognition. Background Art

[0002] The stator and rotor cores of motors are usually made of stacked silicon steel sheets (iron core punching sheets). Silicon steel sheets are usually punched on a punch press using a stamping progressive die. Usually, the stamping progressive die is provided with an upper template, a lower template and a stripper plate located between the upper template and the lower template. A plurality of punches are installed on the upper template, and a concave die matching the punches is installed at the corresponding position of the lower template, thereby forming a plurality of blanking stations. During stamping, the material strip moves forward step by step from between the upper template and the lower template, and punches out through holes, tooth grooves and inner contours on the core punching sheets through the stamping dies (punches and concave dies) on each station in turn. Finally, the core punching sheets are punched off the material strip at the blanking station through the blanking punch and the blanking die. In order to realize the automatic stacking of the core punches, an automatic stacking die is installed under the blanking die of the stamping progressive die. The main component of the automatic stacking die is a tightening ring for accommodating the core punches and having an interference fit with the core punches. During blanking, under the action of the downward punching pressure of the blanking punch, the punched core punches are squeezed into the tightening ring one by one, thereby forming a stacked structure of the core punches in the tightening ring.

[0003] In the prior art, since the material strips used to make the core punching sheets may have certain flatness errors and thickness uneven errors, the core formed after the core punching sheets are stacked may have large thickness uneven errors, which will affect the manufacturing quality of the core. The current solution is to set up a tightening ring rotating device. During operation, each time a core punching sheet is punched, the tightening ring rotating device drives the tightening ring to rotate a certain offset angle, and then the core punching sheets are stacked. However, since the rotation operation of the tightening ring requires a certain cycle time, if the tightening ring is rotated by an offset angle each time a core punching sheet is punched, the working efficiency of the core production line will be significantly reduced.

[0016] The working process of the utility model is as follows:

[0017] (1) After the material strip is punched into a core punch on the core stamping progressive die, it is stacked into a segmented core in the automatic stacking die of the blanking die of the core stamping progressive die; the segmented core is a part of the integral core, and an integral core includes a plurality of segmented cores;

When the iron core is manufactured, the segmented iron core is first formed on the iron core stamping progressive die. The iron core punching sheets do not need to be rotated when stacking the segmented iron core. The stacked segmented iron core is pre-set for offset on the segmented iron core identification rotating device, and is offset stacked on the segmented iron core stacking and shaping press.

[0024] Secondly, the utility model provides a segmented iron core rotating collection, shaping and riveting system based on visual recognition, which utilizes a visual recognition camera to identify the circumferential position of the segmented iron core, thereby ensuring the accuracy of the misaligned stacking of the segmented iron core, thereby ensuring the quality of the subsequent stacking of the segmented iron core into an integral iron core.

[0025] Thirdly, the utility model provides a segmented iron core rotating collection, shaping and riveting system based on visual recognition. A lifting pallet is provided on the segmented iron core collection, stacking and positioning tooling. After each stacking of the segmented iron core is completed, the height position of the upper end surface of the stacked iron core can be kept unchanged by the lifting pallet, which facilitates the positioning operation of the segmented iron core in sequence under the segmented iron core transfer robot and improves the reliability of the segmented iron core positioning.

[0026] Fourthly, the utility model provides a segmented iron core rotating collection, shaping and riveting system based on visual recognition, which realizes the integrated continuous operation of punching, staggered stacking, flattening and stacking packaging, and has a high degree of automation, thereby further improving the work efficiency of iron core production.
