[0001] This application relates to the field of stator lamination processing, and more particularly to a stator lamination or rotor lamination stacking mechanism. Background Technology

[0002] Stator blades, also known as stator laminations, are made by stamping 0.3mm silicon steel sheets into laminations of different specifications to suit the stators of motors with different power ratings.

[0003] Referring to Chinese invention patent CN112928875A, a device for neatly stacking stator laminations of a motor is disclosed, belonging to the field of mechanical technology. This invention includes a frame with a working platform and a circular shaft vertically rotatably mounted on the working platform. A baffle is provided on one side of the circular shaft, and the baffle has a baffle plate for pressing and supporting the stator laminations. A drive source is provided on the frame for driving the circular shaft to rotate around its own axis. The circular shaft consists of a lower shaft, a middle shaft, and an upper shaft arranged coaxially. The lower shaft is rotatably mounted on the working platform and connected to the drive source. Axially arranged connecting holes are provided on the top wall of the lower shaft and the bottom wall of the upper shaft. Shaft bodies are formed on the bottom wall and top wall of the middle shaft, and the two shaft bodies are respectively inserted into the two connecting holes. The two shaft bodies are splinedly engaged with the upper shaft and the lower shaft, respectively. A pressure plate is horizontally arranged directly above the upper shaft, and a drive component for driving the pressure plate to move up and down is provided. The drive component is rotatably connected to the pressure plate. A straight strip-shaped linkage plate is integrally formed on the side wall of the upper shaft.

[0004] In practical use, after stacking stator laminations, it is necessary to remove the stacked stator laminations. This operation often requires manual labor, which is inconvenient and needs to be improved. Summary of the Invention

[0005] To facilitate the collection of stacked stator laminations, this application provides a stator lamination or rotor lamination stacking mechanism.

[0006] This application provides a stator lamination or rotor lamination stacking mechanism, which adopts the following technical solution:

[0007] A stator lamination or rotor lamination stacking mechanism includes a conveyor belt and a mounting base. The conveyor belt is directed toward the mounting base. The mounting base is equipped with a drive component and a positioning roller. The axis of the positioning roller is vertical. The drive component is connected to the positioning roller and drives the positioning roller to move vertically. The drive component also drives the positioning roller to rotate, with the rotation axis of the positioning roller being its own axis. The mechanism further includes a conveyor frame, which is equipped with a conveyor component and a conveyor wheel. The conveyor wheel is used to abut against the bottom of the stator laminations, and its rotation axis is horizontal. The conveyor component drives the conveyor wheel to rotate.

[0008] By adopting the above technical solution, a driving component and a positioning roller are set up. When the stator laminations are stacked to the required number, the driving component drives the positioning roller to move down and support the stacked stator laminations through the conveyor frame. When the positioning roller moves to the point where the stator laminations are separated, the conveyor drives the conveyor wheel to rotate and convey the stacked stator laminations. In this way, it is convenient to move and collect the stacked stator laminations, and the degree of automation of the conveying process is improved.

[0009] Optionally, the mounting base is provided with a limiting vertical bar and a limiting horizontal bar. The limiting horizontal bar extends toward the positioning roller, and a limiting protrusion is provided at the end of the limiting horizontal bar near the positioning roller. The limiting protrusion is used to abut against the bottom of the stator lamination.

[0010] By adopting the above technical solution and setting a limiting protrusion, in actual use, the stator lamination has a notch on its outer peripheral wall. When the positioning roller rotates, the stator lamination is supported by the friction between the limiting block and the outer wall of the positioning roller. Therefore, the stator lamination rotates together with the positioning roller. When the notch of the stator lamination is aligned with the limiting protrusion, the stator lamination moves down. In this way, it is convenient to perform the alignment operation of the stator lamination and to facilitate the subsequent collection of the stator lamination.

[0011] Optionally, the conveyor belt is provided with a guide frame on the side near the mounting base. The guide frame is provided with an inclined plate. The inclined plate extends downward in a direction away from the conveyor belt. The inclined plate is provided with a guide hole. The stator lamination passes through the guide hole and is then fitted into the positioning roller.

[0012] By adopting the above technical solution, in actual use, there is a situation where the stator laminations shift position when moving toward the positioning roller. Therefore, a guide frame is set up, and the stator laminations are moved toward the positioning roller by the inclined plate and guided into the positioning roller through the guide hole, which facilitates the stacking operation of the stator laminations and improves the overall automation level.

[0013] Optionally, the inclined plate includes a guide portion and a limiting portion, with a stepped portion between the guide portion and the limiting portion, the stepped portion connecting the guide portion and the limiting portion, the vertical height of the guide portion near the stepped portion being higher than the vertical height of the limiting portion near the stepped portion, and the guide hole located in the limiting portion; the guide frame is provided with a control component, the control component being connected to a mounting plate, the mounting plate sliding on the guide frame, the sliding direction of the mounting plate being perpendicular to the inclination direction of the inclined plate, and the mounting plate being used to abut against the limiting portion.

[0014] By adopting the above technical solution, in practical use, when stator laminations or rotor laminations are stacked to the required height or quantity, it is necessary to move and collect the stacked stator laminations. Therefore, a control component and a mounting plate are provided. When it is necessary to collect the stacked stator laminations, the drive component drives the positioning roller to move downwards, allowing the stacked stator laminations to be supported by the conveyor frame. At this time, the control component drives the mounting plate to move and abut against the limiting part. When the stator laminations move towards the limiting part, they are limited by the mounting plate. Due to the stepped part, there is a height difference between the limiting part and the guide part, thus causing the moving stator laminations to stack sequentially. The conveyor drives the conveyor wheel to rotate and convey the stacked stator laminations. After the stacked stator laminations are conveyed, the mounting plate moves away from the limiting part, creating a gap between itself and the limiting part for a single stator lamination to pass through. Then, the stator laminations move towards the positioning rollers, and the speed at which the stator laminations pass through the gap between the mounting plate and the limiting part is greater than the speed at which the stator laminations move towards the inclined plate. This reduces the number of stator laminations stacked on the inclined plate. In this way, it is easier to stack stator laminations and reduces the number of times the conveyor belt stops working when the stacked stator laminations are moved and collected, thus improving the stacking efficiency.

[0015] Optionally, the mounting plate is provided with an elastic layer located at one end of the mounting plate near the guide portion, and the elastic layer is used to abut against the stator laminations.

[0016] By adopting the above technical solution and setting an elastic layer, when the mounting plate abuts against the limiting part, the stator lamination will move and impact the mounting plate. Therefore, the elastic layer is used to buffer the movement of the stator lamination and reduce the damage to the stator lamination caused by the impact.

[0017] Optionally, the conveyor belt is provided with a limiting plate, the limiting plate is provided with a sliding groove, the sliding groove is located at the end of the limiting plate away from itself and the connection with the conveyor belt, the sliding groove is provided with a sliding plate, the sliding plate slides in the sliding groove, the limiting plate is provided with a positioning member, the positioning member passes through the limiting plate and is embedded in the sliding plate.

[0018] By adopting the above technical solution, in actual use, there are situations where stator laminations and rotor laminations of different sizes are conveyed. Therefore, a limiting plate and a sliding plate are set. The size of the stator laminations that can pass through is adjusted by moving the sliding plate, and the stator laminations are limited, reducing the positional deviation of the stator laminations during movement.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The installation of drive components and positioning rollers facilitates the movement and collection of stacked stator laminations, thereby improving the automation level of the conveying process;

[0021] 2. A guide frame is set up, which moves the stator laminations toward the positioning rollers by means of an inclined plate, and guides them into the positioning rollers through guide holes, which facilitates the stacking operation of stator laminations and improves the overall level of automation.

[0022] 3. By setting up control components and mounting plates, the stacked stator laminations on the inclined plate are restricted from moving, and the number of times the conveyor belt stops working when the stacked stator laminations are moved and collected is reduced, thus improving the stacking efficiency.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] This application discloses a stator lamination or rotor lamination stacking mechanism. (Refer to...) Figure 1 The system includes a conveyor belt 1, a mounting base 2, and a conveyor frame 3. The conveyor belt 1 is directed towards the conveyor frame 3. The conveyor belt 1 is equipped with a limiting plate 4, which is located on the upper surface of the conveyor belt 1 near the conveyor frame 3. The limiting plate 4 is equipped with a sliding groove 5, located at the end of the limiting plate 4 away from its connection with the conveyor belt 1. The sliding groove 5 extends horizontally and is perpendicular to the conveying direction of the conveyor belt 1. The sliding groove 5 is equipped with a sliding plate 6, which slides within the sliding groove 5 in the direction of the extension of the sliding groove 5. The limiting plate 4 is equipped with a positioning element 7, which passes through the limiting plate 4 and is embedded in the sliding plate 6.

[0029] In practical use, the positioning element 7 can be a positioning bolt, or alternatively, a positioning pin.

[0030] Mounting base 2 is equipped with a driving component 8 and a positioning roller 9. The axis of the positioning roller 9 is vertical. The driving component 8 is connected to the positioning roller 9 and drives the positioning roller 9 to move vertically and rotate. The axis of rotation of the positioning roller 9 is its own axis. The positioning roller 9 has a tapered surface 10, which is located on the side of the positioning roller 9 away from the driving component 8. The tapered surface 10 is tapered in the direction away from the driving component 8. The positioning roller 9 is used for stator laminations to be fitted.

[0031] In practical use, the driving component 8 includes a driving motor and a driving cylinder. The driving motor is connected to the positioning roller 9. The driving motor drives the positioning roller 9 to rotate, and the driving cylinder drives the driving motor and the positioning roller 9 to move in the vertical direction.

[0032] A guide frame 11 is provided on the side of the conveyor belt 1 near the mounting base 2. The guide frame 11 has an inclined plate 12, which extends downward away from the conveyor belt 1. In actual use, the inclined plate 12 includes a guide portion 121 and a limiting portion 122. The limiting portion 122 is located on the side of the guide portion 121 near the mounting base 2. A stepped portion 13 is provided between the guide portion 121 and the limiting portion 122, connecting the guide portion 121 and the limiting portion 122. The vertical height of the guide portion 121 near the stepped portion 13 is higher than the vertical height of the limiting portion 122 near the stepped portion 13. The limiting portion 122 has a guide hole 14, which is located above the positioning roller 9 and passes through the limiting portion 122, allowing the stator laminations to pass through. In actual use, the acute angle between the guide portion and the horizontal plane is greater than the acute angle between the guide portion 121 and the horizontal plane.

[0033] The guide frame 11 is equipped with a control element 15, which is connected to a mounting plate 16. The mounting plate 16 slides on the guide frame 11, and the sliding direction of the mounting plate 16 is perpendicular to the tilting direction of the inclined plate 12. The control element 15 drives the mounting plate 16 to slide, and the mounting plate 16 is used to abut against the limiting part 122 to restrict the stator laminations from moving closer. In actual use, the control element 15 can be a control motor, or alternatively, a control cylinder.

[0034] The mounting plate 16 is provided with an elastic layer 17, which is located at one end of the mounting plate 16 near the guide portion 121. The elastic layer 17 is used to abut against the stator laminations to alleviate the impact of the stator laminations on the mounting plate 16. In this application, the elastic layer 17 can be made of rubber, or alternatively, it can be made of silicone.

[0035] Mounting base 2 is provided with a limiting vertical rod 18 and a limiting horizontal rod 19. The length direction of the limiting vertical rod 18 is vertical, and the limiting horizontal rod 19 is connected to the side wall of the limiting vertical rod 18 away from the mounting base 2. The limiting horizontal rod 19 extends towards the positioning roller 9. A limiting protrusion 20 is provided at the end of the limiting horizontal rod 19 near the positioning roller 9. The limiting protrusion 20 is used to abut against the bottom of the stator lamination. In actual use, when the stator lamination moves and fits into the positioning roller 9, the limiting protrusion 20 abuts against the bottom of the stator lamination. When the positioning roller 9 rotates, the stator lamination rotates together. When the stator lamination rotates to the point where its notch aligns with the limiting protrusion 20, the stator lamination moves.

[0036] The conveyor frame 3 is located on the side of the conveyor belt 1 near the mounting base 2. The conveyor frame 3 is equipped with a conveyor component 21 and a conveyor wheel 22. The conveyor wheel 22 is used to abut against the bottom of the stator lamination. The axis of rotation of the conveyor wheel 22 is horizontal. The conveyor component 21 drives the conveyor wheel 22 to rotate. In actual use, the conveyor component 21 is a conveyor motor.

[0037] The implementation principle of a stator lamination or rotor lamination stacking mechanism according to an embodiment of this application is as follows: In actual use, the conveyor belt 1 transports the stator laminations or rotor laminations. The stator laminations move towards the mounting base 2 and enter the inclined plate 12. After passing through the guide part 121 and the stepped part 13, the stator laminations move along the extension direction of the limiting part 122 and are fitted into the positioning roller 9 through the guide hole 14. At this time, the limiting protrusion 20 abuts against the bottom of the stator lamination, and the positioning roller 9 rotates, causing the stator lamination to rotate. When the notch of the stator lamination is aligned with the limiting protrusion 20, the stator laminations move down and stack.

[0038] When the stacked stator laminations need to be transported, the control unit 15 drives the mounting plate 16 to move and abut against the limiting part 122, thus restricting the stator laminations from moving toward the guide hole. The drive unit 8 drives the positioning roller 9 to move downward, so that the stacked stator laminations are supported by the conveyor frame 3. When the positioning roller 9 moves to the point where the stator laminations are separated, the conveyor 21 drives the conveyor wheel 22 to rotate and transport the stacked stator laminations. When the stacked stator laminations are moved, the control unit 15 drives the mounting plate 16 to move, leaving a gap between the mounting plate 16 and the limiting part 122, which facilitates the movement of the stator laminations toward the guide hole 14.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
