Description

Technical Field

[0001] The present invention relates to the technical field of stator assembly, and particularly to a stator paper inserting machine. Background Art

[0002] The stator is the stationary part of a motor or a generator, and mainly consists of a stator core and coils wound around the stator core. In order to ensure that the coils on the stator do not interfere with each other, insulating paper sheets need to be inserted into the winding grooves of the stator as a separator layer. In traditional factories, the paper sheets are mainly inserted manually, and the paper inserting efficiency is relatively low; currently, factories mainly use paper inserting machines to insert the paper sheets, thereby improving the paper inserting efficiency.

[0003] When using a paper inserting machine to insert insulating paper into the winding grooves, it is first necessary to form the insulating paper and then insert it into the winding grooves of the stator. When the existing paper inserting machine forms the insulating groove paper, its feeding, cutting, and forming actions are not continuous. It is necessary to first cut the insulating groove paper into appropriately sized insulating groove paper blocks, and then put the insulating groove paper blocks into a forming die for forming, which greatly reduces the production efficiency. On the other hand, there are various specifications for the winding grooves of the stator, resulting in a variety of forming dies for the bottom paper of the grooves. Most of the existing paper inserting machines can only insert paper for a stator winding groove of one specification. When inserting paper for the bottom paper of other specifications of grooves, large-scale modifications and replacements are required, and the replacement operation is cumbersome, the die changing time is long, and the efficiency is low, which greatly increases the manufacturing cost of the stator.

An adjustment component 1 is provided on the upper wheel shaft, and the adjustment component 1 can adjust the gap and pressure between the upper paper pressing wheel and the lower pressing wheel to obtain an indentation of appropriate depth. First, the paper roll is guided to the upper paper pressing wheel through the guide wheel column, driving the lower wheel shaft to rotate, thereby driving the lower gear to rotate, and the lower gear drives the upper gear meshing with it to rotate, so that the upper paper pressing wheel and the lower paper pressing wheel rotate in coordination to press a crease on the paper roll.

[0009] Furthermore, in the above-mentioned stator paper inserting machine, the paper feeding mechanism includes a paper feeding paperboard, the paper feeding paperboard is provided with a paper feeding shaft rotatably connected thereto, one end of the paper feeding shaft is connected to a paper feeding wheel, and the other end is connected to a drive, one side of the paper feeding wheel is provided with a paper feeding idler wheel, the paper feeding idler wheel is arranged on an idler wheel seat and rotatably connected to the idler wheel seat, and the idler wheel seat is fixed to the base plate through an adapter plate.

A plurality of guiding wheels symmetrically arranged on both sides of the pressing plate are arranged on the guiding plate, and the guiding wheels on both sides are arranged to shrink towards the side of the pressing plate in the upward direction, that is, the included angle between the corresponding guiding wheels on both sides gradually decreases until the central axes of the uppermost group of guiding wheels are parallel; a first forming cavity is arranged in the lower forming knife, and the opening of the first forming cavity is smaller at the top and larger at the bottom. The rolled paper with indentations is conveyed upward from the paper passing bottom plate. Through the action of a plurality of guiding wheels and the pressing plate, the two sides of the rolled paper are curled towards the pressing plate to form a trapezoid and enter the first forming cavity of the lower forming knife. The first forming cavity is trapezoidal, and the rolled paper is trapezoidal after coming out of the first forming cavity.

[0011] Furthermore, for the above-mentioned stator paper inserting machine, the upper forming mechanism includes a first die base, a second die base and an upper forming knife.

[0013] Further, for the above stator paper inserting machine, the cutter mechanism includes a cutter, a cutter seat, and a pressing block. The cutter is arranged on the cutter seat. The cutter seat is fixed on the slider of the third slide rail. The third slide rail is fixed on the front side of the substrate. The cutter seat is connected to an eccentric transmission mechanism II. Symmetrically arranged pressing blocks are arranged above the lower forming cutter. The two pressing blocks form a T-shaped groove located above the first forming cavity. Guided by the T-shaped groove, the movement of the cutter is more accurate. The cutter is inserted into the T-shaped groove and is slidably connected to the T-shaped groove through the eccentric transmission mechanism II, driving the cutter to move along the T-shaped groove, so as to cut the roll paper.

[0014] Further, for the above stator paper inserting machine, a first driving mechanism and a second driving mechanism are also arranged at the rear side of the vertical plate. The first driving mechanism drives the paper pressing mechanism and the paper feeding mechanism. The second driving mechanism drives the eccentric transmission mechanism I and the eccentric transmission mechanism II. Both the first driving mechanism and the second driving mechanism include a servo motor and a synchronous belt transmission mechanism. The servo motor provides power for the two mechanisms through the synchronous belt transmission mechanism at the same time. The servo motor of the first driving mechanism provides power for the lower wheel shaft and the paper feeding rotating shaft through the synchronous belt transmission mechanism. The servo motor of the second driving mechanism provides power for the rotating wheel through the synchronous belt transmission mechanism.

[0015] The eccentric transmission mechanism I and the eccentric transmission mechanism II have the same structure, including a spherical plain bearing, a connecting rod, a rotating wheel, a slider, and a slider shaft.

A slider slidably connected thereto is arranged in the slideway. The slider shaft is connected to the slider. The slider shafts of the eccentric transmission mechanism I and the eccentric transmission mechanism II are arranged staggeredly. Thus, the cutter and the upper forming cutter work alternately under the action of the second driving mechanism, so that the final forming and cutting of the bottom paper of the slot are carried out alternately and continuously.

[0016] Further, for the above stator paper inserting machine, the indexing mechanism includes an indexing base plate and an indexing disc. The indexing disc is provided on the indexing base plate. The indexing disc is provided with paper inserting slots corresponding to the winding slots of the stator and a positioning structure for positioning the stator. A motor is fixed below one side of the indexing base plate. The indexing disc is connected to the motor through a gear transmission mechanism. A turning seat fixed on a vertical plate is further provided on the side of the indexing base plate away from the motor. A lead screw is provided on the turning seat. An adjusting nut threadedly connected to the lead screw is provided on the lead screw. The adjusting nut is connected to the indexing base plate. Above the indexing base plate, a pressing plate assembly is further provided. The pressing plate assembly includes a rotary cylinder, a connecting plate, and a pressing and warping plate. The rotary cylinder is fixed on the indexing base plate. The output end of the rotary cylinder is connected to the connecting plate. The other end of the connecting plate is adjustably connected to the pressing and warping plate, and the installation height of the pressing and warping plate can be adjusted. During paper insertion, the rotary cylinder drives the pressing and warping plate to rotate above the stator, and then the pressing and warping plate is lowered. The pressing and warping plate presses on the upper end face of the stator to prevent the stator sheets forming the stator from warping during paper insertion.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Before forming, creases are pressed on the roll paper by the pressing mechanism, making the forming in the forming mechanism faster and more accurate. Moreover, during the forming process, the actions of paper pressing, paper feeding, forming, paper cutting, and paper pushing are coherent, and continuous production can be carried out, accelerating the forming speed of the bottom paper of the slot and improving the production efficiency. When changing the mold, the connection between the forming module and the vertical plate is loosened, and the mold changing trolley is connected to the base plate of the forming module. The mold changing trolley is pushed, and the mold changing trolley pushes the forming module out of the vertical plate, making the mold change fast and simple, and greatly improving the production efficiency.
