Description

Technical Field

[0001] The invention relates to the technical field of motor production, and in particular to a feeding device for a motor stator and a stator positioning method. Background Art

[0002] There are different types of motors in the market, which are used for different applications according to their functions. As the quality of materials used in these types of motors continues to improve, the performance of these motors is also improving. In motors such as motors and generators, the stator is one of the most important parts. The current of the stator can be provided from the rotating part of the system. The motor needs to assemble the stator, rotor and other parts during the production process. The assembly of the automotive stator and the housing is generally carried out by heating the housing and then clamping the stator into the housing using equipment. Before the equipment is clamped, the stator must be placed in a specified position. This process is called stator online.

[0003] In the related art, there are two ways to put the stator online: one type uses a hoist to support the inner hole of the stator, and then uses a KBK crane to hoist the stator. The worker manually positions the stator and places it on the line positioning tooling plate. The other is to use a robot to clamp the stator and directly place it on the line positioning tooling plate. However, using a hoist to hoist the stator is simple in structure and economical, but placing the stator on the tooling plate is difficult to position and there is a risk of collision. Although the method of using a robot to put the stator online is convenient for positioning, the one-time investment is high, and the stator must be accurately positioned before it goes online. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the related technology, the positioning accuracy of the stator on-line is low, and the positioning is difficult and there is a risk of collision.

[0033] First, as Figure 1 As shown, the present application provides a feeding device for a motor stator, which comprises: a support 1, a positioning plate 2 and at least two initial positioning columns 6; wherein,

[0034] The positioning plate 2 is connected to the support 1 through a flip driving assembly 3, and the flip driving assembly 3 is used to drive the positioning plate 2 to flip. The positioning plate 2 is provided with a positioning block 4, and the positioning plate 2 limits the axial displacement of the stator 5, and the positioning block 4 is used to limit the rotation of the stator 5. At least two initial positioning columns 6 are installed on the positioning plate 2, and the two initial positioning columns 6 are used to support the side of the stator 5, and the two initial positioning columns 6 are configured as follows:

[0035] When the stator 5 is supported on the two initial positioning columns 6 , the stator 5 is aligned with the tooling plate in the axial direction.

[0036] Furthermore, the surface of the initial positioning post 6 is an arc surface, and the arc surface can slide, roll and cooperate with the stator 5 so that the stator 5 can perform axial or circumferential movement on the two initial positioning posts 6 .

[0037] When in use, the side wall of the stator 5 can be hoisted by a magnetic crane, and the stator 5 can be placed horizontally on the two initial positioning columns 6. At this time, the stator 5 is supported by the initial positioning columns 6 that have been pre-adjusted and aligned with the positioning plate 2 in the axial direction. Then the stator 5 is manually driven to rotate on the initial positioning columns 6 until the guide groove of the stator 5 is aligned with the positioning block 4 in the axial direction of the stator 5. Then the stator 5 is pushed to engage with the positioning block 4. At this time, the axial end face of the stator 5 is against the positioning plate 2, and the stator 5 cannot continue to approach the positioning plate 2 in the axial direction. Then, the positioning plate 2 is driven to flip to the preset position by the flip drive assembly 3 to complete the positioning of the stator 5.

[0038] It is understandable that the present application sets an initial positioning column 6 that slides with the stator, and uses the positioning column to preliminarily position the height of the stator after it is dropped, so that the stator can be dropped in a horizontal posture and directly aligned with the positioning plate in height. Furthermore, the stator of the present application can align the guide groove of the stator with the positioning block by performing circumferential movement on the initial positioning column, and then push the stator in to complete the axial displacement limit with the positioning plate, and finally flip it. By hoisting the stator horizontally, it can ensure that the positioning operation is completed without damaging the stator, thereby greatly shortening the operation time of stator loading.

[0039] In some preferred embodiments, the positioning plate 2 is provided with a limiting hole 23 for partially passing the stator 5 , and the limiting hole 23 abuts against a partial area of ​​the axial end surface of the stator 5 .

[0040] It is understandable that if Figure 4 As shown, the aperture of the limiting hole 23 needs to be determined according to the structure of the stator 5. After the stator 5 is placed on the initial positioning column 6, the axial end surface of the stator 5 is aligned with the limiting hole 23 of the positioning plate 2. The limiting hole 23 allows the end of the stator 5 to pass through and abut against the step surface in the middle of the stator 5 to complete the axial limiting.

[0041] Optionally, the positioning plate 2 may be provided with a groove matched with the stator 5 , and the groove is used to limit the axial displacement of the stator 5 .

[0042] Furthermore, the positioning block 4 is detachably mounted on the first large surface 21 of the positioning plate 2 , and the positioning block 4 is located at the edge of the limiting hole 23 .

[0043] It can be understood that the first large surface 21 of the positioning plate 2 is used to cooperate with the axial end surface of the stator 5 to limit its axial displacement. The positioning block 4 is clamped in the guide groove of the stator 5 and abuts against the positioning block 4 in the axial direction of the stator 5. Further, when the end surface of the stator 5 core falls into the limiting hole 23 on the positioning plate 2, the limiting hole 23 part cooperates with the small clearance of the outer circle of the stator 5. At this time, the stator 5 is fixed by the positioning plate 2 in the axial direction and fixed by the positioning block 4 in the circumferential direction.

[0044] In some specific implementations, a protrusion is provided on the surface of the positioning block 4 , and the protrusion of the positioning block 4 is used to limit and cooperate with the guide groove on the side of the stator 5 .

[0045] It is worth noting that the protrusion on the surface of the positioning block 4 can be an arc-shaped protrusion, and the arc-shaped protrusion is aligned with the guide groove on the outer side of the stator 5.

[0046] In some specific implementations, in order to improve the stability of the positioning mechanism, the support 1 includes two support seat plates and a bottom plate. The positioning plate 2 is provided between the two support seat plates. Furthermore, a linear guide rail 7 is installed below the bottom plate of the support 1, and the entire support 1 is carried on the linear guide rail 7, and the support 1 can reciprocate along the linear guide rail 7 through the bottom plate.

[0047] In some preferred embodiments, a counterweight 24 is provided on the second large surface 22 of the positioning plate 2 opposite to the first large surface 21. Figure 1 and Figure 3 As shown, two counterweights 24 are provided on the second large surface 22 of the positioning plate 2 .

[0048] It can be understood that the counterweight 24 is used to ensure that the center of gravity of the entire flipping mechanism is colinear with the flipping axis 32, thereby ensuring the stability of the flipping process.

[0049] In some optional implementations, a buffer 11 is provided on the bottom surface of the support 1 , and the buffer 11 is used to abut against the second large surface 22 of the positioning plate 2 to limit the flipping angle of the positioning plate 2 .

[0050] It is worth noting that the buffer 11 is used to limit the positioning plate 2, and the flipping angle of the positioning plate 2 can be adjusted by setting the height of the buffer in advance.

[0051] In some specific implementations, the flip driving assembly 3 includes: a driving member 31 and a flip shaft 32; wherein,

[0052] A driving member 31 is received in the support 1 ; a flip shaft 32 is connected to the driving member 31 , and the flip shaft 32 is at least partially disposed in the positioning plate 2 .

[0053] It is worth noting that the two sides of the flip shaft 32 are respectively connected to the driving members 31 in the two supporting base plates of the support 1.

[0054] Optionally, the driving member 31 can be driven by a motor or a cylinder. The driving member 31 is connected to the flip shaft 32 through a transmission assembly.

[0055] Preferably, the transmission assembly can be driven by gears.

[0056] Specifically, the transmission assembly includes a cylindrical gear shaft, a cylindrical gear, a gear bar and a tooth groove. The cylindrical gear shaft is mounted on the support 1. The cylindrical gear is mounted on the cylindrical gear shaft, and the gear shaft is clamped in the support plate on the right. The rack groove and the gear groove side are fixed together, and the rack is placed in the gear groove and just meshes with the cylindrical gear. The end of the rack groove is connected to the driving member 31, and the driving member 31 is mounted as a whole on the cylinder support plate.

[0057] When in use, after the stator is in place, press the start button, the cylinder pushes the gear bar to move linearly, the gear bar meshes with the cylindrical gear, under the linear motion of the gear bar, the gear slowly rotates, and the gear shaft in the middle of the gear starts to rotate, thereby driving the positioning plate 2 in the stator positioning mechanism to flip.

[0058] In some optional embodiments, a support plate 61 is provided on the positioning plate 2, and the support plate 61 is used to accommodate the initial positioning column 6. The initial positioning column 6 is axially arranged parallel to the stator 5, and the side surface of the initial positioning column 6 can be matched with the sliding surface.

[0059] Preferably, in order to facilitate adjustment, the support plate 61 is provided with a slide rail, and the initial positioning column 6 can move along the slide rail, thereby adjusting the distance between the two initial positioning columns 6, and then adjusting the height of the stator 5 after being horizontally dropped, so as to facilitate alignment and positioning.

[0060] In some optional embodiments, the feeding device further includes a position detection switch for detecting the position of the positioning plate 2. When the positioning plate 2 is flipped to a preset position, the position detection switch sends a signal. The line guide rail 7 drives the upper support 1, the positioning plate 2, and the stator 5 to move as a whole to the stator grabbing station.

[0061] In a second aspect, the present application provides a stator loading method using the above-mentioned motor stator loading device, which comprises:

[0062] Step S1, placing the stator 5 on two initial positioning posts 6 in a horizontal posture, and driving the stator 5 to rotate on the two initial positioning posts 6 until the guide groove of the stator 5 and the positioning block 4 are aligned in the circumferential direction of the stator 5.

[0063] Specifically, the stator 5 is lifted by a magnetic crane and placed horizontally on the two initial positioning columns 6. At this time, the stator 5 is aligned with the corresponding limiting position of the positioning plate 2 in the axial direction.

[0064] Step S2 , pushing the stator 5 until a portion of the positioning plate 2 is used to abut against an axial end surface of the stator 5 .

[0065] Specifically, the stator 5 is rotated to ensure that the guide groove on the outside of the stator 5 is aligned with the arc protrusion of the positioning block 4. Then the stator 5 is pushed until Figure 1 As shown, the core end face of the stator 5 falls into the limiting hole 23 or groove of the positioning plate 2. At this time, the limiting hole 23 or groove and the outer circle of the stator 5 are matched with a small gap. At this time, the stator 5 is fixed by the positioning plate 2 in the axial direction and locked by the positioning block 4 in the circumferential direction.

[0066] Step S3: driving the positioning plate 2 to flip to a preset position via the flip driving assembly 3.

[0067] Specifically, Figure 2 As shown, pressing the button of the flip driving assembly 3 drives the positioning plate 2 to flip. After the positioning plate 2 flips into place, the buffer 11 is used to limit the position to ensure the reliability of the final position.

[0068] Step S4, the support 1, the stator 5, the positioning plate 2 and other components are driven to translate to a preset designated position as a whole through the linear guide rail 7.

[0069] In summary, the present application sets an initial positioning column that slides with the stator, and uses the positioning column to preliminarily position the height of the stator after it is dropped, so that the stator can be dropped in a horizontal posture and directly aligned with the positioning plate in height. Furthermore, the stator of the present application can align the guide groove of the stator with the positioning block by performing circumferential motion on the initial positioning column, and then push the stator in to complete the axial displacement limit with the positioning plate, and finally flip it over. By hoisting the stator horizontally, it can ensure that the positioning operation is completed without damaging the stator, thereby greatly shortening the operation time of stator loading. It solves the problem that the coordination of the hoisting stator with the positioning plate and the positioning block is time-consuming, because there is no fulcrum when the stator is in the air, and the coordination is difficult. There is also the risk of collision between the stator bottom wire package and the positioning plate and the positioning block, which may cause the wire package to be damaged.
