Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insulating paper inserting into the stator core of a new energy vehicle motor, and in particular to an insulating paper inserting device for a stator of a driving motor of a new energy vehicle. Background Art
[0002] At present, new energy vehicles are developing vigorously around the world, and the drive motor is one of the core components of new energy vehicles. In the manufacturing process of the stator assembly of the drive motor, it is necessary to insert the insulating paper into the stator core to achieve the insulation function between the winding and the core.
[0003] Traditional paper insertion equipment mostly adopts a method of pushing the paper into the slot by a push rod, such as patent publication number: CN112531993A, CN117411260A, etc., which disclose a method of pushing the paper into the slot by a push rod. The use of a push rod to push the paper into the slot has the following disadvantages: First, the beat is slow. During the process of pushing the paper into each slot, the push rod needs to reciprocate, and the distance moved by the push rod is twice the length of the paper; second, the end surface of the insulating paper after molding is easily damaged when the push rod pushes the paper. In order to solve the above problems, the present invention proposes a method of paper feeding driven by double rollers. By rotating the rollers, the rollers generate friction with the surface of the paper, directly driving the paper forward, and inserting the paper into the slot of the stator core. This method has a fast paper feeding speed and a large paper feeding force, and the production efficiency and quality are greatly improved. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] The device comprises: a stator loading and unloading turntable 1, a paper forming and feeding mechanism 3, a paper roll mechanism 4, and a stator positioning and lifting unit 6. The paper forming and feeding mechanism 3 comprises: a paper pressing wheel 31, a paper length control code 32, a creasing wheel 33, a folding mechanism 34, a double paper feeding drive wheel 35, a dust cover 36, a paper cutter 37, a paper feeding drive transmission structure, and a paper feeding drive motor.
[0025] The stator core is loaded to the stator core loading position 5 by the transfer robot, and the stator loading turntable 1 rotates the core to the paper insertion position 2, and the stator is positioned and lifted to the working position by the stator positioning and lifting unit 6. The paper roll 4 is stored on the paper roll positioning mechanism, and the paper forming and feeding mechanism 3 forms the paper tape into a rectangular shape and inserts it into the stator core.
[0026] The paper forming and feeding mechanism 3 includes: a paper pressing wheel 31, a paper length control encoder 32, a creasing wheel 33, a folding mechanism 34, a double paper feeding drive wheel 35, a dust cover 36, a paper cutter 37, a paper feeding drive motor 38, a drive transmission structure 39, etc.
[0027] The strip-shaped paper roll 4 passes through the paper guide groove and the paper pressing wheel 31. The paper pressing wheel assembly is equipped with an encoder 32 for controlling the paper length to detect the paper feeding length in real time. After passing through the paper pressing wheel, the paper tape enters the creasing wheel assembly 33. Through the cooperation of the raised sharp edge on the upper creasing wheel 331 and the groove on the lower creasing wheel 332, the corresponding folding marks are pressed out to facilitate the folding forming. The folding tape with the marks passed downwards through the folding mechanism 34. The folding mechanism is equipped with a paper guide groove 371 and a paper pressing strip 373. After passing through the paper guide groove and the paper pressing strip, the cross-sectional shape of the paper is bent from a strip shape to a U shape. The U-shaped paper tape passes through the folding molds 372 arranged on the left and right and finally passes through the closing mold 373 to be folded into the required shape.
[0028] During the whole paper feeding process, the double paper feeding driving wheel 35 provides power. There are two sets of paper feeding driving mechanisms, which are arranged symmetrically on the left and right. The driving power is transmitted by the paper feeding driving motor 38 through the synchronous belt transmission to the driving transmission structure 39. The left paper feeding driving wheel 351 and the right paper feeding driving wheel 352 are driven through the synchronous belt and the paper feeding transmission structure 354. The double paper feeding driving wheel 35 is provided with a clamping mechanism 353. The cylinder drives the two sets of paper feeding driving wheels to clamp the U-shaped paper tape from both sides, so that a certain friction force is generated between the paper feeding driving wheel and the paper tape, driving the paper tape to move, and at the same time providing power for the molded paper to be inserted into the stator slot to realize the paper insertion function.
