Description

Technical Field

[0001] The utility model belongs to the technical field of motor manufacturing, and in particular relates to a paper inserting device and motor production equipment. Background Art

[0002] A flat wire motor uses a stator wound with flat conductors (usually copper wire). Compared to traditional round wire motors, flat wire motors offer numerous design and performance advantages. Due to their high power density and efficiency, flat wire motors are widely used in the drive systems of new energy vehicles, providing strong power and long driving range.

[0003] Currently, during the production and processing of flat-wire motor stators, insulating paper must be inserted into the stator slots to ensure insulation between the flat-wire windings inserted into the stator slots and the stator core. Before inserting the insulating paper, it must be folded into a shape that fits the stator slots and then inserted into the stator slots to facilitate insertion of the flat wires.

[0004] However, in the prior art, paper is mostly inserted from the bottom up. Sometimes the burrs in the stator slots are directed downward. Inserting the paper from the bottom up goes against the direction of the burrs, making it inconvenient to insert the paper. Moreover, when inserting the paper from the bottom up, the force acting on the stator is directed upward. Therefore, a fixing member needs to be applied above the stator to prevent the stator from being lifted up and causing warping, resulting in low structure and low paper insertion accuracy.

[0035] See also Figures 1 to 3The present invention provides a paper insertion device 100 and a motor production device 300 having the same. The paper insertion device 100 is used to insert insulating paper 101 into the slots of the stator 400. The insulating paper 101 is wound on a material tray, and the insulating paper 101 is fed into the paper insertion device 100 through the material tray. The insulating paper 101 is made of an insulating material.

[0036] The paper insertion device 100 includes:

[0037] See also Figures 1 to 3 , the frame includes a mounting plate 102 and a mounting plate 103 provided on the upper surface of the mounting plate 102, and the stator 400 is fixed below the mounting plate 102;

[0038] The indentation structure 11 receives the insulating paper 101 to be indented from the material tray and is used to indent the insulating paper 101, so as to respectively indent two side indentations on the two side edges of the insulating paper 101, and indent two center indentations on the insulating paper 101, and the two center indentations are arranged at intervals and are both located between the two side indentations.

[0039] See also Figures 1 to 3 The bending structure 12 includes a first bending mechanism 14 for receiving the insulating paper 101 from the discharge port of the indentation structure 11 and a second bending mechanism 15 for receiving the insulating paper 101 from the first bending mechanism 14. The first bending mechanism 14 is used to bend the insulating paper 101 along the side indentations, and the second bending mechanism 15 is used to bend the insulating paper 101 along the two center indentations and make the two side edges of the insulating paper 101 overlap;

[0040] See also Figures 1 to 3 The paper pushing structure 13 is used to press the insulating paper 101 from the second bending mechanism 15 downward into the stator 400 slot of the stator 400. The indentation structure 11, the bending structure 12 and the paper pushing structure 13 are all connected to the mounting plate 103.

[0041] See also Figures 1 to 3 It is understood that the first bending mechanism 14 bends the two side edges of the insulating paper 101 along the two side indentations, and the second bending mechanism 15 bends the insulating paper 101 along the two middle indentations, and then overlaps the two side edges of the insulating paper 101, thereby turning and bending the insulating paper 101 into an insulating paper sleeve 101 with a rectangular cross-section. The insulating paper sleeve 101 is then inserted into the positioning slot by the paper pushing mechanism 13, thereby electrically isolating the flat wires in the stator 400 slots from the stator 400.

[0042] See also Figures 1 to 3The paper insertion device 100 provided in the embodiment of the present application can bend the insulating paper 101 into a specific shape so that the insulating paper 101 can adapt to the shape of the stator 400 slot of the stator 400. The outlet of the second bending mechanism 15 is aligned with the stator 400 slot, and the paper pushing structure 13 pushes the insulating paper 101 located at the second bending mechanism 15 and already bent into the stator 400 slot downward, while the burrs of the stator 400 slot face downward, so that the insulating paper 101 is inserted into the positioning slot in the direction of the burrs, avoiding paper jams and improving the convenience of inserting the insulating paper 101. At the same time, since the stator 400 is fixed under the mounting plate 102, during the insertion process of the insulating paper 101, the stator 400 will not cause the edge of the stator 400 to warp, thereby improving the assembly accuracy of the stator 400 and the insulating paper 101.

[0043] See also Figures 1 to 3 Optionally, the indentation structure 11 includes an upper indentation roller 111 and a lower indentation roller 112 cooperating with the upper indentation roller 111, and the upper indentation roller 111 and the lower indentation roller 112 are both rotatably connected to the mounting vertical plate 103, and the insulating paper 101 is located between the upper indentation roller 111 and the lower indentation roller 112.

[0044] See also Figures 1 to 3 Optionally, by integrating the indentation structure 11, bending structure 12, and paper-pushing structure 13 on the same mounting plate 103, the overall stability and space utilization of the device are improved, allowing maintenance and component replacement from above, improving the convenience of maintenance and replacement. The indentation structure 11 ensures the folding accuracy of the insulating paper 101, reducing errors caused by manual operation; the bending structure 12, through two bends, overlaps the edges of the insulating paper 101, facilitating subsequent insertion; and the paper-pushing structure 13 ensures that the insulating paper 101 can be smoothly and accurately inserted into the stator 400 slot, improving production efficiency and assembly accuracy.

[0045] See also Figures 1 to 3 In some embodiments, the first bending mechanism 14 includes a pre-bending mold 141, a flanging mold 142 spaced apart above and below the pre-bending mold 141, and a transmission assembly located between the pre-bending mold 141 and the flanging mold 142.

[0046] See also Figures 1 to 3Optionally, the pre-bending mold 141 and the flanging mold 142 each have a pre-bending cavity 1411 and a flanging cavity. After the insulating paper 101 passes through the pre-bending cavity 1411 and the flanging cavity, the two side edges of the insulating paper 101 can be flanging and tilting along the side edge indentations. The cooperation between the pre-bending mold 141 and the flanging mold 142 allows the side edges of the insulating paper 101 to be precisely bent according to the predetermined side edge indentations, thereby improving bending accuracy. The transmission assembly ensures that the insulating paper 101 maintains stable movement during the bending process, preventing displacement and deformation of the paper during the bending process.

The transmission driver 145 can be a servo motor.

[0049] See also Figures 1 to 3 Optionally, the driving roller 143 and the driven roller 144 are patterned to increase friction between the driving roller 143, the driven roller 144, and the insulating paper 101. The driving roller 143 and the driven roller 144 ensure smooth and continuous movement of the insulating paper 101 during transmission. The servo motor provides a stable driving force, allowing the insulating paper 101 to pass smoothly through the first bending mechanism 14, avoiding slippage or jamming during transmission.

[0050] See also Figures 1 to 3 In some embodiments, the transmission assembly further includes two oppositely arranged fixed plates 146 and fixed columns whose ends are respectively connected to the two fixed plates 146, wherein one fixed plate 146 is connected to the mounting vertical plate 103, and the two ends of the active roller 143 are respectively rotatably connected to the two fixed plates 146, and a rotation groove 1461 is provided on the fixed plate 146, and the two ends of the driven roller 144 are respectively actively set in the rotation groove 1461, and a compression spring 147 and an adjusting pressure block 148 that presses the compression spring 147 toward the driven roller 144 are also provided in the rotation groove 1461.

[0051] See also Figures 1 to 3 Optionally, gears are provided on both the active roller 143 and the driven roller 144 , and the two gears are engaged, so that the driven roller 144 and the active roller 143 can rotate synchronously, thereby improving the smoothness of the transmission of the insulating paper 101 .

[0052] Optionally, the provision of a fixed plate 146 and a fixed column enhances the structural stability of the transmission assembly. The provision of a rotation slot 1461 and a compression spring 147 ensures flexibility and adaptability in adjusting the driven roller 144. By adjusting the vertical position of the adjustment pressure block 148, the tightness of the compression spring 147 can be adjusted, thereby adjusting the gap between the active roller 143 and the driven roller 144. This allows for adaptability to insulating paper 101 of varying thicknesses, ensuring uniform pressure on the insulating paper 101 during transmission and preventing damage to the paper due to uneven pressure.

The receiving trough 1513 is used to receive the insulating paper 101 from the flanging die 142. The forming plate presses the insulating paper 101 in the receiving trough 1513 into the forming groove 1512 through the avoidance groove 1514, so that the insulating paper 101 can fit the inner wall of the forming groove 1512 and be precisely bent into shape.

[0055] Optionally, the forming groove 1512 , the material receiving groove 1513 and the avoidance groove 1514 all pass through both ends of the forming mold 151 in the vertical direction.

[0056] See also Figures 3 to 5 At the discharge end 1511 of the forming mold, the two side walls of the forming groove 1512 gradually approach each other in the horizontal direction, so that the two side edges of the insulating paper 101 are bent relative to the two side indentations, so that when the insulating paper 101 leaves the discharge end 1511, the two side edges of the insulating paper 101 are in an overlapping state. Figure 4The forming process of the insulating paper 101 is given. The insulating paper 101 is about to enter the receiving trough 1513. The insulating paper 101 is pressed into the forming trough 1512 by the forming plate.
