[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0049] Referring to Figures 1 to 18 , an embodiment of the present invention provides a stator core assembly machine, which includes a frame 1, and the frame 1 is provided with: a first feeding groove 20, a housing position adjusting mechanism, a material distributing mechanism, a second feeding groove 40, a core positioning mechanism, and a clamping and inserting frame mechanism. A plurality of insulating shells 91 can be placed side by side in the first feeding groove 20; the housing position adjusting mechanism is used to drive the insulating shells 91 in the first feeding groove 20 to move so that all the insulating shells 91 face the same direction; the material distributing mechanism includes a first driving device and a plurality of material pushing forks 355, and the first driving device can drive all the material pushing forks 355 to push the insulating shells 91 together along the first feeding groove 20 to adjust the distance between the insulating shells 91; a plurality of cores 92 can be placed side by side in the second feeding groove 40; the core positioning mechanism is used to position all the cores 92 in the second feeding groove 40; the clamping and inserting frame mechanism includes a clamping device capable of clamping a plurality of insulating shells 91 from the first feeding groove 20, a traveling mechanism capable of driving the clamping device to move to the second feeding groove 40, and an ejecting device capable of ejecting the insulating shells 91 on the clamping device and sleeving them on the cores 92.

[0050] Preferably, the frame 1 includes a bottom plate 11 fixedly installed on the ground or other devices and a fixed bracket 12.

[0051] In the present invention, generally, a device such as a conveyor belt is used to drive the insulating shells 91 to enter the first feeding groove 20 from one end. In order to initially limit the insulating shells 91 in the first feeding groove 20, a limiting column 201 is provided at one end of the first feeding groove 20.

[0052] Referring to Figure 1 And Figure 2 , a first baffle 21 is provided on the bottom plate 11. The housing position adjusting mechanism includes a first pressing plate 22 and a second driving device 23 capable of driving the first pressing plate 22 to move closer to and away from the first baffle 21. The first feeding groove 20 is formed between the bottom plate 11, the first pressing plate 22, and the first baffle 21. After a whole row of insulating shells 91 enter the first feeding groove 20, all the insulating shells 91 are closely adjacent to each other, and the longer arc sides of all the insulating shells 91 are located on the side where the first baffle 21 is located, but the orientations of the respective insulating shells 91 are different. At this time, the second driving device 23 drives the first pressing plate 22 to press the insulating shells 91 against the first baffle 21, which can adjust the positions of the insulating shells 91 so that the edges on both sides of the front side of the insulating shells 91 are pressed against the first pressing plate 22, and the symmetry axes of all the insulating shells 91 are substantially perpendicular to the first pressing plate 22. The second driving device 23 is preferably a cylinder. Of course, other power devices such as a motor and a hydraulic cylinder can also be used as an alternative to the cylinder.

[0053] This article provides two embodiments of the material distribution mechanism, and the similarities of the two embodiments are as follows:

[0054] The first feed trough 20 is a linear trough arranged along the left-right direction (i.e., the Y-axis direction), and the material distribution mechanism also includes a track plate 31 and a guide rail seat 32. The first driving device includes a material distribution driver 331 that can drive one of the track plate 31 and the guide rail seat 32 to move relative to the other along the X-axis. A longitudinal guide 34 parallel to the Y-axis is provided on the guide rail seat 32. All material shifting forks 35 are installed on the longitudinal guide 34, and each material shifting fork 35 can be independently moved along the longitudinal guide 34. A plurality of guide grooves 311 are provided on the track plate 31, and the inclination of each two adjacent guide grooves 311 relative to the X-axis is different. Each material shifting fork 35 corresponds to a guide groove 311, and each material shifting fork 35 is provided with a thrust member 351, which is inserted into the corresponding guide groove 311 and can move along the guide groove 311.

[0055] Optionally, a cylinder mounting seat 312 is provided at the bottom of the track plate 31 , and the material distribution driver 331 is a cylinder mounted on the cylinder mounting seat 312 .

[0056] Reference Figure 6 and Figure 8 When the thrust member 351 moves in the guide groove 311, the difference in Y-axis coordinates between the starting point and the end point of the thrust member 351 is the above-mentioned tilt amount. Preferably, the starting point and the end point of the thrust member 351 are respectively arranged at the two ends of the guide groove 311. The guide groove 311 is generally a straight groove. In some special working conditions, the guide groove 311 can also be arranged as an arc-shaped or other curved groove.

[0057] Furthermore, the difference between the inclinations of every two adjacent guide grooves 311 is a fixed value, that is, the inclinations of all guide grooves 311 form an arithmetic progression. This design ensures that when the present invention performs material separation, the distances opened by each material separation fork 355 are equal.

[0058] In order to reduce friction, the thrust member 351 is configured as a rolling member pivotally connected to the material shifting fork 355 and capable of rolling in the guide groove 311. In a specific embodiment of the present invention, the longitudinal guide member 34 is a guide rail, the material shifting fork 355 includes a slide seat 352 disposed on the longitudinal guide member 34, and a shifting rod 353 having one end fixed on the slide seat, and the rolling member is pivotally connected to the slide seat 352. In certain embodiments of the present invention, the longitudinal guide member 34 may also be replaced by a guide rod or the like.

[0059] The differences between the two embodiments are as follows:

[0060] Reference Figure 6, in Embodiment 1 of the material distribution mechanism, the above-mentioned track plate 31 is fixed to the bottom plate 11 or the fixed bracket 12, and its working principle is as follows: First, a whole row of insulating shells 91 is conveyed along the Y-axis direction to the first feeding groove 20 through a conveying mechanism such as a conveyor belt. At this time, the pushing member 351 on the material separating fork 35 is located at the rightmost end of the guiding groove 311; then, under the driving action of the above-mentioned material distribution driver 331, the guide rail seat 32 moves leftward along the X-axis, driving the material separating fork 35 to move along each guiding groove 311, and the left ends of each shifting rod 33 are inserted into the slots 911 on the insulating shell 91 or into the gaps between the insulating shells 91. During the insertion process, the displacements of every two adjacent shifting rods 33 in the Y-axis direction are different, so that the insulating shells 91 can be separated by an appropriate distance. After the material distribution is completed, the positioning of these insulating shells 91 is completed.

[0061] Referring to Figures 7 to 9 , in Embodiment 2 of the material distribution mechanism, the track plate 31 and the guide rail seat 32 are both arranged on the bottom plate 11 and can move along the X-axis on the bottom plate 11. The left end of the material separating fork 35 is a material distribution end for cooperating with the insulating shell. The first driving device further includes an inserting driver 332 capable of driving the track plate 31, the guide rail seat 32, and all the material separating forks 35 to move leftward along the X-axis together.

[0062] To ensure the stability of the movement of the track plate 31 and the guide rail seat 32, a transverse guide rail 111 parallel to the X-axis is provided on the bottom plate 11, and both the guide rail seat 32 and the track plate 31 are installed on the transverse guide rail 111 through sliding seats.

[0063] Optionally, the inserting driver 332 is a cylinder installed on the bottom plate 11, and the piston rod of the cylinder is connected to the guide rail seat 32.

[0064] The working principle of Embodiment 2 is as follows: First, a whole row of insulating shells 91 is conveyed along the Y-axis direction to the first feeding groove 20 through a conveying mechanism such as a conveyor belt. At this time, the pushing member 351 on the material separating fork 35 is located at the leftmost end of the guiding groove 311. Then, under the driving action of the inserting driver 332, the track plate 31, the guide rail seat 32, and all the material separating forks 35 move leftward along the X-axis together, so that the left ends of each shifting rod 33 are inserted into the slots 911 on the insulating shell 91 or into the gaps between the insulating shells 91. During the insertion process, the displacement of all the shifting rods 33 in the Y-axis is zero; then the guide rail seat 32 and the longitudinal guiding member 34 remain stationary, and the material distribution driver 331 drives the track plate 31 to move leftward, driving each material separating fork 35 to move along the longitudinal guiding member 34 through each guiding groove 311, so that the insulating shells 91 can be separated by an appropriate distance.

[0065] Referring to Figures 10 to 12, a second baffle 41 is provided on the bottom plate 11. The iron core positioning mechanism includes a preliminary positioning device and a secondary positioning device. The preliminary positioning device includes a preliminary positioning plate 42 located on one side of the second baffle 41. The preliminary positioning plate 42 is driven by a driving device to move closer to and away from the second baffle 41. A second feeding groove 40 is formed between the bottom plate 11, the preliminary positioning plate 42 and the second baffle 41. The secondary positioning device includes a secondary positioning plate 43. A plurality of positioning bumps 431 are arranged side by side on the secondary positioning plate 43. The distance between adjacent positioning bumps 431 is equal. The secondary positioning plate 43 is driven by a driving device so that the positioning bumps 431 can be inserted into the gaps between the iron cores 92.

[0066] Preferably, the width of the positioning bump 431 gradually decreases from its fixed end to its free end. A push plate 46 is provided on one side of the second baffle 41. The preliminary positioning plate 42 is arranged between the push plate 46 and the second baffle 41. The preliminary positioning plate 42 and the push plate 46 are connected by a compressible elastic connecting member 45. The secondary positioning plate 43 is installed on the push plate 46. The preliminary positioning plate 42 and the secondary positioning plate 43 adopt the same driving device. The output end of the driving device is connected to the push plate 46 and can drive the push plate 46 to move closer to and away from the second baffle 41. The above driving device is preferably a cylinder 44, and the elastic connecting member 45 is preferably a cylindrical spring.

[0067] The push plate 46 is provided with a front-back guiding hole 461. The preliminary positioning plate 42 is connected with a guiding rod 47 that cooperates with the guiding hole 461. The guiding rod 47 passes through the guiding hole 461. A limiting block 471 protruding from the front side of the push plate 46 is provided at the front end of the guiding rod 47.

[0068] In the present invention, generally, a device such as a conveyor belt is used to drive the insulating shell 91 to enter from one end of the second feeding groove 40. In order to preliminarily limit the insulating shell 91 in the second feeding groove 40, a limiting block 401 is provided at one end of the second feeding groove 40.

[0069] The working principle of the iron core positioning mechanism is as follows: First, a row of iron cores 92 are conveyed between the second baffle 41 and the preliminary positioning plate 42, such that the longer arc side of the iron core 92 is on the side where the second baffle 41 is located. Then, the driving device operates to drive the pressing plate 46 and the preliminary positioning plate 42 to move backward together. When the preliminary positioning plate 42 presses against each iron core 92, it can adjust the position of the iron core 92, causing the edges on both sides of the front side of the iron core 92 to press against the preliminary positioning plate 42. The symmetry axis of the iron core 92 is substantially perpendicular to the preliminary positioning plate 42, and a V-shaped gap that gradually narrows from front to back is formed between adjacent iron cores 92. Next, the pressing plate 46 continues to move backward, compressing the elastic member, and causing the positioning protrusion 431 on the secondary positioning plate 43 to insert into the gap between the iron cores 92, thereby performing secondary positioning on the iron cores 92 and further finely adjusting the position of the iron cores 92 to keep the sizes of the gaps between the respective iron cores 92 substantially the same.

[0070] In certain embodiments of the present invention, the above-mentioned preliminary positioning mechanism may also adopt other structural forms. For example, a method of using a magnet to adsorb the iron cores 92 is adopted, such that all the iron cores 92 are in contact with the second baffle 41 and all the iron cores 92 face the same direction.

[0071] Referring to Figures 13 to 15 , the clamping device includes: a base 51, a lifting seat 52, and a plurality of clamping seats 53. A lifting driver 54 capable of driving the lifting seat 52 to move up and down relative to the base 51 is provided on the base 51; all the clamping seats 53 are arranged side by side in the left-right direction at the lower part of the lifting seat 52. A clamping groove 50 for inserting the insulating shell 91 is formed between adjacent clamping seats 53, and an elastic member capable of clamping the insulating shell 91 in the clamping groove 50 is provided on the clamping seat 53.

[0072] The ejecting device includes a plurality of ejecting rods 56 provided on the lifting seat 52. The lower end of each ejecting rod 56 faces a clamping groove 50 and can eject downward the insulating shell 91 located in the clamping groove 50. An ejecting driver 57 capable of driving all the ejecting rods 56 to move up and down relative to the lifting seat 52 together is also provided on the lifting seat 52.

[0073] The process of clamping the insulating shell 91 is as follows: When the clamping device moves to the upper part of the first feeding trough 20 along with the traveling mechanism, the lifting driver 54 operates to drive the lifting seat 52 to move downward, so that the insulating shell 91 is inserted into the corresponding material clamping groove 50. At this time, the elastic member deforms to clamp the insulating shell 91, and then the lifting driver 54 drives the lifting seat 52 to move upward, thus completing the work of clamping the insulating shell 91. The process of ejecting the insulating shell 91 is as follows: First, the lifting driver 54 drives the lifting seat 52 and the ejector rod 56 on the lifting seat 52 to move downward by a certain distance together. After the lifting seat 52 reaches the predetermined position, the ejecting driver 57 operates to drive the ejector rod 56 to extend into the corresponding material clamping groove 50, and eject the insulating shell 91 from the material clamping groove 50 and sleeved on the corresponding iron core 92.

[0074] As a preferred embodiment of the present invention, the elastic member is a spring piece 55 arranged on the side part of the material clamping seat 53. Both ends of the spring piece 55 are connected to the material clamping seat 53. The part between the two end parts of the spring piece 55 is the deformation part, and the deformation part is arc-shaped and bulges in the direction away from the material clamping seat 53 connected thereto. In each material clamping groove 50, generally two spring pieces 55 are arranged, and the two spring pieces 55 are respectively installed on the material clamping seats 53 on both sides of the material clamping groove 50; of course, only one spring piece 55 can also be arranged. For example, the left side part of the material clamping groove 50 has a spring piece 55, and there is no spring piece 55 on the right side.

[0075] Furthermore, the output end of the ejecting driver 40 is connected with an ejector rod mounting plate 58, and all the ejector rods 56 are installed at the bottom of the ejector rod mounting plate 58. A longitudinal limiting groove is arranged on the side wall of the material clamping seat 53, and both ends of the deformation part are embedded in the limiting groove, and the middle part of the deformation part extends out from the opening of the limiting groove. Such a structure can limit the spring piece 55, so that the spring piece 55 can only elastically deform in the left and right directions. In addition, the maximum stroke of the spring piece 55 is also limited to prevent defective products with larger volume from excessively squeezing the spring piece 55 to cause the spring piece 55 to fail.

[0076] The upper end surface of the material clamping seat 53 is provided with a first clamping groove, and the lower end surface of the material clamping seat 53 is provided with a second clamping groove. The upper end part of the spring piece 55 is clamped in the first clamping groove, and the lower end part of the spring piece 55 is clamped in the second clamping groove.

[0077] Refer to Figure 13 , a motor seat is arranged on the upper part of the base 51. The lifting driver 54 includes a motor arranged on the motor seat, and the output end of the motor is connected with the lifting seat 52 through a lead screw pair. A cylinder seat is arranged on the upper part of the lifting seat 52. The ejecting driver 57 includes a cylinder arranged on the cylinder seat, and the output end of the cylinder is connected with an ejector rod 56 mounting plate, and all the ejector rods 56 are installed at the bottom of the ejector rod 56 mounting plate.

[0078] In some embodiments of the present invention, the lifting driver 54 can also adopt devices such as air cylinders, and the ejecting driver 57 can also adopt devices such as motors. The above elastic member can also adopt other structural forms. For example, an arc-shaped plate can be used to replace the deformation part of the spring piece 55, and a spring is connected between the arc-shaped plate and the material clamping seat 53; or an elastic colloid can be directly used to replace the above spring piece 55.

[0079] In this embodiment, the second feed chute 40 is arranged in front of the first feed chute 20 and is parallel to the first feed chute 20. The traveling mechanism includes a guiding chute 71 arranged on the fixed bracket 12, a guide rail 72 that cooperates with the guiding chute 71 and is fixedly connected to the base 51, and a main air cylinder 73 that can drive the base 51 to move back and forth along the guiding groove 311.

[0080] Referring to Figure 16 And Figure 17 , an insertion slot 911 with a downward opening is provided on the insulating shell 91. The iron core 92 has an insertion portion 921 that can be inserted into the insertion slot 911 and is in interference fit with the insulating shell 91. An expanding slot member 6 is further provided on the frame 1. A plurality of expanding slot blocks 61 that can be inserted into the insertion slot 911 are provided on the expanding slot member 6. An expanding slot driver 62 that can drive the expanding slot member 6 to move so that all the expanding slot blocks 61 move above the second feed chute 40 is further provided on the frame 1. The expanding slot driver 62 is preferably an air cylinder. Preferably, the upper part of the expanding slot block 61 is in the shape of a wedge with a narrow upper part and a wide lower part.

[0081] The working principle of the present invention is as follows: First, the insulating shell 91 enters the first feeding groove 20 until the insulating shell 91 is blocked by the limit post 201, and the iron core 92 enters the second feeding groove 40 until the iron core 92 is blocked by the limit stop 401. Then, the second driving device 23 operates to drive the first pressing plate 22 to move close to the first baffle 21, so that all the insulating shells 91 in the first feeding groove 20 face the same direction. Next, the first driving device operates to drive the material shifting fork 355 to insert into the slots 911 of each insulating shell 91 or the gaps between each insulating shell 91, and shift each insulating shell 91 to keep a set distance between each insulating shell 91. At the same time, the iron core positioning mechanism operates to perform secondary positioning on the iron core 92 in the second feeding groove 40. Then, the main cylinder 73 of the traveling mechanism operates to drive the clamping device to move above the first feeding groove 20. Then, the lifting driver 54 operates to drive the lifting seat 52 to move downward, and grip the insulating shell 91 through the clamping groove 50 between the clamping seats 53. After the lifting seat 52 rises to the moving height, the main cylinder 73 drives the entire clamping device to move above the second feeding groove 40. Then, the groove expanding driver 62 drives the groove expanding member 6 to move so that the groove expanding block 61 moves between the clamping device and the second feeding groove 40. Then, the lifting driver 54 drives the lifting seat 52 to move downward, so that the groove expanding block 61 is inserted into the slot 911 of the insulating shell 91. After the insulating shell 91 is slightly expanded, it is inserted into the iron core 92. When the insulating shell 91 is inserted into the iron core 92 slightly, the groove expanding block 61 withdraws from the slot 911, and the lifting driver 54 continues to drive the lifting seat 52 to insert downward until the insulating shell 91 is completely inserted into the iron core 92. Then, the ejecting driver 57 presses the ejecting rod 56 against the insulating shell 91, and the lifting driver 54 lifts the lifting seat 52, and the ejecting rod 56 ejects the insulating shell 91 from the clamping groove 50, that is, the installation of the insulating shell 91 on one side of the iron core 92 is completed. After the iron core 92 is turned over, another insulating shell 91 is installed on the other side of the iron core 92 by similar steps as above, and the assembly of the stator iron core 92 can be completed.

[0082] Compared with the prior art, the present invention can assemble multiple iron cores 92 and insulating shells 91 together at one time, and the entire working process is automatic, with high automation degree and improved working efficiency.

[0083] The above is only the preferred implementation mode of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
