Description

Technical Field

[0001] The present invention relates to an insulating paper inserting device for a new energy stator, and more specifically, to a guiding and fixing structure of a stator slot insulating paper inserting device and a working method thereof. Background Art

[0002] The insulating paper insertion device is a device used to accurately insert insulating paper into the stator or rotor slot of a motor. It mainly includes a paper feeding mechanism, a forming mechanism, a paper cutting mechanism and a paper inserting mechanism. Its working principle is to feed the raw insulating paper from the paper roll, and cut the insulating paper into a suitable length to meet the needs of stators and rotors of different specifications, and after cutting, fold it to form a shape that matches the slot of the stator coil, so that the insulating paper can be more easily inserted into the slot and fit with the inner wall of the slot. The insulating paper insertion operation can be performed quickly and continuously, reducing the time required for production.

[0003] However, the current insulating paper insertion device is difficult to operate and requires special training for staff to use it proficiently. In addition, due to the large distance between the paper cutting mechanism and the motor stator, a slender columnar object is required to guide the insulating paper during the insertion process of the insulating paper. However, the strength of the object is poor and it is easy to bend and break during the guiding process, resulting in poor use effect. It needs to be replaced after a period of use, which increases the cost of use. If the object used for guidance needs to be reinforced, its volume will inevitably increase, resulting in damage to the insulating paper when pushed in, affecting the qualified rate of the finished product and producing unqualified products.

A turntable is provided between the paper pushing guiding structure and the paper pushing structure, and the turntable is used to drive the paper inserting device to switch between different workstations, so that the paper inserting operation on the processing stator can be efficiently performed, thereby improving the processing efficiency. At the same time, a transmission assembly is provided between the paper pushing guiding structure and the turntable, and the transmission assembly is configured to allow the paper pushing guiding structure to rotate along the central axis of the paper pushing guiding structure in the turntable. A paper pushing guiding structure is provided on the paper pushing guiding structure, and the paper pushing guiding mechanism has a guide bar for guiding the insulating paper that has been cut and folded, and a guide bar connecting block connected to the guide bar, and the guide bar connecting block can extend to the outside of the paper pushing guiding structure, thereby fixing the guide bar during the process of pushing the guide bar, and effectively preventing the guide bar from being bent and damaged during the process of pushing the insulating paper.

[0019] 2. Furthermore, the paper cutting device includes a paper cutting knife frame arranged at the bottom of the turntable, the paper cutting knife frame is provided with a paper cutting knife, and the paper cutting knife is arranged on the paper cutting knife frame through a driving assembly, and the driving assembly has a transmission gear and a transmission frame, and a transmission rod is provided on the outer peripheral surface of the transmission gear, and the transmission frame is rotatably connected with the transmission rod, and the other end of the transmission frame is installed with the paper cutting knife. Specifically, when the transmission gear rotates, the transmission rod makes a circular motion with the transmission gear, and the transmission frame is rotatably connected with the transmission rod. The rotating rod can convert the circular motion of the transmission gear into a reciprocating motion of the paper cutting knife on the paper cutting knife frame, and the rotation speed of the transmission gear is fixed, so that the time spent on a reciprocating motion of the paper cutting knife on the paper cutting knife frame remains unchanged, so that the size of the insulating paper obtained by a single cutting remains consistent, so that the insulating paper cutting is consistent with the folded finished product, thereby improving the qualified rate of the inserted processed stator finished product, and the processing effect is good.

[0020] 3. At the same time, in order to facilitate the insertion of the insulating paper during the paper insertion process and to prevent the guide strip from being damaged when pushing the paper, the paper insertion device includes a guide strip push cylinder arranged at the bottom of the paper pushing guide structure, and a paper pushing cylinder is also arranged at the bottom of the guide strip push cylinder. A plurality of paper pushing rods are also arranged in the paper pushing structure, and the paper pushing rods are distributed along the circumference. A connecting plate is also arranged between the paper pushing rod and the paper pushing cylinder, and the connecting plate is used to fix the paper pushing rod. Specifically, after the cut and folded insulating paper is inserted into the interior of the paper insertion device, the paper pushing cylinder drives the paper pushing rod to move in the direction of the paper pushing guide structure, and at the same time, the paper pushing paper board on the paper pushing cylinder is inserted into the paper pushing guide structure and the channel in the transmission assembly through the paper outlet hole, so that the folded insulating paper enters the paper feed path arranged between the paper pushing guide strip and the tooth guard belt through the paper pushing rod, and because the cross-sectional size of the paper feed path = the size of the mounting hole < the size of the paper outlet hole = the cross-sectional size of the paper pushing rod, the paper pushing rod pushes the folded insulating paper After being pushed into the paper feeding channel, since the cross-sectional size of the paper pushing rod is greater than the cross-sectional size of the paper feeding channel, the paper feeding channel is configured to allow the insulating paper to enter and at least block the paper pushing rod at the bottom of the insulating paper, so that after the insulating paper is inserted into the paper feeding channel, the paper pushing rod conflicts with the bottom of the paper pushing guide strip, and pushes the paper pushing guide strip and the tooth guard belt to move toward the mounting structure, thereby realizing the function of inserting the insulating paper into the paper insertion slot of the processing stator. At the same time, a guide strip connecting block is also provided in the paper pushing guide structure, and at least 2 / 3 of the guide strip connecting block extends to the outside of the paper pushing guide structure. After the paper pushing guide strip is pushed to the stator mounting plate, since a guide strip connecting block is provided on one side of it, the paper pushing guide strip can be blocked by the guide strip connecting block after being subjected to pressure from the outside thereof, thereby preventing the paper pushing guide strip from bending, improving the processing effect, and preventing the paper pushing guide strip from bending and breaking during the processing, increasing the qualified rate of the processed finished product, and reducing the frequency of replacing the paper pushing guide strip, thereby reducing the processing cost.

[0021] 4. In addition, during the processing, by detecting inside the stator slot before processing, the problem of not placing the processed stator before processing can be avoided. At the same time, after the installation is completed, the insulating paper is cut by a paper cutter and automatically folded during the process of pushing into the paper insertion device, so that the insulating paper entering the paper insertion device is in a shape matching the paper insertion slot of the processed stator, and then guided by the paper pushing rod of the paper insertion device, so that the insulating paper is inserted into the processing stator through the paper pushing rod and the guide bar to complete the paper insertion of the single processing stator paper insertion slot. The overall processing efficiency is high, and after the processing is completed, the device can further control the stator installation device according to whether the processing of the entire processing stator is completed. Specifically, when the stator slot rotates to the next sequence, if there is insulating paper in the stator slot, it is determined that all stator slots of the current processing stator are inserted with insulating paper, and the processing of the processing stator is completed, and a new processing stator needs to be placed again for processing.
