[0002] The stator core is the core basic component of a motor. Inserting insulating paper into the stator slots is a key process in motor stator manufacturing. The insulating paper mainly serves to provide insulation and isolation within the slots, prevent breakdown, prevent leakage, and protect the winding coils. Its insertion accuracy, integrity, and flatness directly determine the motor's insulation performance, operational safety, service life, and overall yield. Therefore, the stator core stator slot paper insertion device is an indispensable step in the motor stator manufacturing process.

[0003] The existing paper insertion device for the stator core and stator slot of the motor still has the following problems when inserting insulating paper: 1. During the process of inserting insulating paper, it is necessary to manually feed the insulating paper. The manual feeding of the insulating paper can easily cause deformation of the insulating paper, affecting the insulating paper effect and quality. 2. During the process of applying insulating paper, due to the different specifications of the motor stator, it is impossible to adjust according to the specifications of the motor stator. This can easily affect work efficiency when fixing the motor stator with insulating paper. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-9 In this embodiment of the invention, a paper insertion device for inserting paper into the stator slot of a motor stator core includes a housing 1. An adjusting roller frame mechanism 6 is provided on the upper part of one end of the housing 1, and a clamping and supporting paper conveying frame mechanism 7 is installed on one side of the upper end of the insulating paper platform 2. A control box 8 is installed at one corner of the upper end of the insulating paper platform 2.

[0030] More specifically, the adjusting roller frame mechanism 6 includes a cylinder 61, which is symmetrically installed on one side of the push beam 62. Support columns 63 are symmetrically installed on the upper end of the push beam 62, and a movable roller 64 is connected to the upper pin between the support columns 63 and the support columns 63.

[0031] With the above technical solution, when placing the motor stator 5, the cylinder 61 is controlled to work, and when the cylinder 61 works, it drives the push beam 62 to move, and at the same time drives the support column 63 to slide inside the insulating paper platform 2. While the support column 63 is sliding, the position of the moving roller 64 at the upper end of the insulating paper platform 2 and the distance between the moving roller 64 and the fixed roller 4 are adjusted, so as to facilitate the support and placement of motor stators 5 of different specifications.

[0032] More specifically, the clamping and supporting paper conveying frame mechanism 7 includes a connecting plate 71, with vertical plates 72 symmetrically mounted on the upper end of the connecting plate 71, and a motor 73 mounted on the side of the vertical plate 72. The output shaft of the motor 73 is keyed to the outer wall of a rotating tube 74, and a driving tube 75 is mounted on the outer wall of the rotating tube 74. A first bevel gear 76 is symmetrically mounted on the outer wall of the driving tube 75, and a conveying roller 77 is mounted in the middle of the outer wall of the driving tube 75. A clamping roller mechanism 78 is mounted on the upper part of the inner wall of the vertical plate 72.

[0033] More specifically, the clamping roller mechanism 78 includes a support plate 781, a clamping roller 782 is provided at the upper end of the support plate 781, and the clamping roller 782 is installed on the outer wall of the connecting shaft 783. A guide plate 784 is symmetrically installed at the upper end of the support plate 781, and a second bevel gear 785 is installed on the bottom outer wall of the connecting shaft 783.

[0034] According to the above technical solution, the insulating paper is folded according to the shape of the stator slot of the motor stator 5. After folding, the insulating paper is placed on the upper end of the conveying roller 77. The conveying roller 77 and the clamping roller 782 cooperate to maintain the shape of the insulating paper. Then, while the insulating paper maintains its shape, the motor 73 drives the conveying roller 77 to rotate. At the same time, the first bevel gear 76 and the second bevel gear 785 mesh. When the conveying roller 77 rotates, it drives the clamping roller 782 to rotate at the same time, which facilitates the conveying of the insulating paper. When inserting the insulating paper, the insulating paper passes between the guide plates 784, which facilitates the guiding of the insulating paper during the process and prevents the insulating paper from bending due to excessive length, which would affect the insulating effect.

[0035] More specifically, the rotating tube 74 passes through the middle of the interior of the vertical plate 72 and a bearing is provided at the connection point; the first bevel gear 76 and the conveying roller 77 are arranged between the vertical plates 72.

[0036] More specifically, the connecting shaft 783 passes through the middle of the support plate 781 and a bearing is provided at the connection point; the clamping rollers 782 are respectively arranged on both sides above the conveying roller 77, and the first bevel gear 76 and the second bevel gear 785 are meshed together.

[0037] More specifically, the cylinder 61 is symmetrically installed on the upper part of one end of the housing 1 and extends through it; the support column 63 slides through the symmetrically opened sliding holes inside the insulating paper platform 2, and the upper end of the moving roller 64 is horizontally set with the upper end of the fixed roller 4, while the motor stator 5 is placed above the fixed roller 4 and the moving roller 64.

[0038] More specifically, a motor is installed on the outer side of the fixing plate 3, and the output shaft of the installed motor is keyed to the fixing roller 4.

[0039] More specifically, an insulating paper platform 2 is installed on the upper end of the aforementioned chassis 1, and a fixing plate 3 is symmetrically installed on one side of the upper end of the insulating paper platform 2. A fixing roller 4 is installed on the upper part between the fixing plate 3 and the fixing plate 4, and a motor stator 5 is placed on one side above the fixing roller 4.

[0040] More specifically, the control box 8 contains, in sequence, electrical components such as intermediate relays, air switches, changeover switches, emergency stop buttons, circuit breakers, contactors, displays, and PLCs. These electrical components form a widely used "PLC three-level control" system in this field. Using this system to control the electrical components is an existing technology and will not be described in detail here.

[0041] Please see the appendix Figure 8-9 The insulating paper mechanism 9 includes a fixed frame 91 fixed to the housing 1; an mounting plate 92 is installed on the fixed frame 91; two transverse linear modules 93 are installed on the mounting plate 92, and transfer frames 94 are installed on the two transverse linear modules 93; a longitudinal transfer module 95 is provided on the transfer frame 94; a sliding frame 96 is provided on the longitudinal transfer module 95; and a paper suction nozzle assembly 97 and a folding cylinder 98 are provided on the sliding frame 96.

[0042] More specifically, there are two paper suction nozzle assemblies 97; a paper folding knife 99 is fixed to the end of the cylinder rod of the folding cylinder 98. A paper storage trough 910 is also fixed to one side of the fixed frame 91; several insulating papers are stacked inside the paper storage trough 910.

[0043] By adopting the above technical solution, the insulating paper can be automatically picked up and folded in half so that it can be inserted into the stator.

[0044] The working principle of this invention is as follows: When insulating paper needs to be transported into the equipment, the transverse linear module 93 drives the transfer frame 94 to move to the right, so that the paper suction nozzle assembly 97 is placed in front of the paper storage trough 910. Then, the longitudinal transfer module 95 drives the sliding frame 96 to move forward, and the two paper suction nozzle assemblies 97 are used to pick up the insulating paper. After the insulating paper is picked up, the longitudinal transfer module 95 drives the sliding frame 96 to move backward. Then, the transverse linear module 93 drives the transfer frame 94 to move to the left, moving the insulating paper between the two clamping rollers 782. Subsequently, the transverse linear module 93 drives the transfer frame 94 to move to the right, so that the folding knife 99 is in the middle position of the insulating paper, the cylinder rod of the folding cylinder 98 extends, and the folding knife 99 pushes the middle position of the insulating paper. With the cooperation of the two clamping rollers 782, the insulating paper is made into a V shape.

[0045] During the actual operation, the motor stator 5 is placed on the upper end of the fixed roller 4 and the moving roller 64, the absorbed insulating paper is placed on the upper end of the conveying roller 77, and the inserted insulating paper is folded by the paper folding knife 99. Finally, the insulating paper is conveyed through the guide plate 784 to the stator slot of the motor stator 5, thereby completing the slotting work of the insulating paper. During the placement of the motor stator 5, the cylinder 61 is controlled to work, and when the cylinder 61 works, it drives the push beam 62 to move, and at the same time drives the support column 63 to slide inside the insulating paper platform 2. While the support column 63 is sliding, the position of the moving roller 64 at the upper end of the insulating paper platform 2 and the distance between the moving roller 64 and the fixed roller 4 are adjusted to facilitate the support and placement of motor stators 5 of different specifications. During the insertion of insulating paper, the insulating paper is folded according to the shape of the stator slot of the motor stator 5. After folding, the insulating paper is placed on the upper end of the conveying roller 77. The conveying roller 77 and the clamping roller 782 work together to maintain the shape of the insulating paper. While the insulating paper is in shape, the motor 73 drives the conveying roller 77 to rotate. At the same time, the first bevel gear 76 and the second bevel gear 785 mesh. When the conveying roller 77 rotates, it drives the clamping roller 782 to rotate at the same time, which facilitates the conveying of the insulating paper. When inserting the insulating paper, the insulating paper passes between the guide plates 784 to facilitate the conveying of the insulating paper and prevent the insulating paper from bending due to excessive length, which would affect the insulation effect.
