[0053] The stator lamination support assembly 23 includes a support plate 231 and several support rods 232; the support plate 231 is hollowed out in the middle to form a ring shape; the support rods 232 are arranged around the bottom of the support plate 231 and are fixedly connected to the bottom of the support plate 231; the bottom of the support rods 232 is fixedly connected to the top of the turntable 22; when the second drive assembly 21 drives the turntable 22 to rotate, it directly drives the support plate 231 to rotate.

[0054] The stator lamination support assembly 23 also includes several limiting rods, which are spaced around the inner wall of the support plate 231; a limiting cylinder is sleeved around the outer periphery of the limiting rods, and the limiting cylinder is abutted against the inner wall of the support plate 231 to limit the position of the stator laminations, thereby increasing the accuracy of the equipment.

[0055] The dispensing device 3 includes a support frame 31, a third drive device 32, and a stamping box 34. The support frame 31 is slidably mounted on the top of the table. The support frame 31 is arranged in a "7" shape and includes a horizontal bar and a vertical bar. One end of the horizontal bar is fixedly mounted on the top of the vertical bar. A fixing plate 33 is fixedly mounted on the end of the horizontal bar away from the vertical bar. A mounting plate is fixedly mounted on the bottom of the fixing plate 33. The third drive device 32 is fixedly mounted on the top of the mounting plate. The side of the third drive device 32 facing the fixing plate 33 is fixedly connected to the side wall of the fixing plate 33 away from the horizontal bar. The output end of the third drive device 32 passes through the mounting plate from top to bottom and is vertically downward. The output end of the third drive device 32 is fixedly connected to the top of the stamping box 34 to drive the stamping box 34 to reciprocate in the vertical direction.

[0056] The stamping box 34 has a hollow interior with a material cavity for filling with glue. The top and bottom of the material cavity are shaped to match the shape of the stator laminations. A partition plate is fixedly installed on the outer periphery of the material cavity. An installation cavity is opened on the side of the partition plate away from the material cavity. The installation cavity surrounds the outer periphery of the material cavity. A stamping component is installed in the installation cavity. The stamping component surrounds the outer periphery of the material cavity. The bottom of the stamping component matches the stator laminations.

[0057] Two fourth drive components 35 are fixedly installed on the top of the stamping box 34; the output end of the fourth drive component 35 passes through the top of the stamping box 34 and is fixedly connected to the stamping component to drive the stamping component to reciprocate in the vertical direction.

[0058] Preferably, the fourth drive component 35 is a cylinder.

[0059] The bottom of the material cavity of the stamping box 34 extends downward to form an adhesive coating section, the shape of which is consistent with the shape of the stator sheet; the size of the adhesive coating section is smaller than the size of the stator sheet to reduce the amount of adhesive overflowing from the stator sheet during operation.

[0060] The glue coating section has several glue outlet holes that are spaced apart. A glue column is slidably embedded in the glue outlet hole. The upper end of the glue column is a cylinder and the lower end is a cone. The outer diameter of the cone decreases from top to bottom. Several elastic strips are fixedly installed at intervals on the outer circumference of the top of the glue column. The other end of the elastic strips is fixedly installed on the top of the glue coating section in the material cavity.

[0061] When the coating section is not in contact with the stator laminations, the glue column is pulled by the elastic strip and embedded in the glue outlet hole. The cylindrical part of the glue column blocks the glue outlet hole, while the conical part protrudes from the glue outlet hole and is exposed on the outer side of the bottom of the coating section. When the coating section is in contact with the stator laminations, the glue column is pushed by the squeezing force and retracts into the material cavity until the tip of the conical part is flush with the bottom of the coating section. The cylinder is pushed out of the glue outlet hole, so that the glue outlet hole is in the glue dispensing state. The glue in the material cavity flows out onto the stator lamination through the gap between the conical part and the glue outlet hole, thus realizing the glue coating operation.

[0062] The stator lamination manufacturing equipment also includes a fifth drive assembly, which is fixedly installed on the top of the table. The output end of the fifth drive assembly is connected to the dispensing and feeding device 3 to drive the dispensing and feeding device 3 to reciprocate in the horizontal direction of the table, so as to move closer to or away from the stacking device 2.

The seventh drive assembly is fixedly installed on the top of the connecting cylinder, and the output end of the seventh drive assembly is fixedly connected to the top of the lifting rod to drive the lifting rod to reciprocate in the vertical direction. A pressing member 44 is fixedly installed at the bottom of the lifting rod for pressing the stacked stators.

[0065] The cover 41 includes an outer cylinder 411, an inner cylinder 412, and a cover plate; the outer cylinder 411 is spaced around the outer periphery of the inner cylinder 412, and the top and bottom of the outer cylinder 411 and the inner cylinder 412 are flush; the cover plate is fixedly covered on the top of the outer cylinder 411 and the inner cylinder 412 to close the top of the outer cylinder 411 and the inner cylinder 412.

[0066] Both the outer cylinder 411 and the inner cylinder 412 are cylindrical.

[0067] The outer cylinder 411 and the inner cylinder 412 are spaced apart to form an air cavity; the bottom of the outer cylinder 411 and the inner cylinder 412 are covered with a sealing plate to seal the bottom of the air cavity.

[0068] Several through holes 413 are provided through the inner cylinder 412, so that the air chamber is connected to the interior of the inner cylinder 412 through the through holes 413; the through holes 413 are arranged in an array on the cylinder wall.

[0069] The cover plate at the top of the air chamber has an air channel, through which the air chamber is connected to an externally installed air extraction or heating device. When the cover 41 is placed over the outer periphery of the stacked stator, the bottom of the cover 41 abuts against the top of the turntable 22 to form a nearly enclosed space. When the adhesive is anaerobic, air is extracted from the cover 41 through the air chamber and through holes, making the internal space of the cover 41 a nearly oxygen-free space, thus accelerating the curing of the adhesive. When the adhesive is heating type, heating gas is injected into the cover 41 through the air chamber and through holes to accelerate the curing of the adhesive.

[0070] The top of the turntable 22 is recessed and has an annular groove; the annular groove is located below the cover 41 and matches the bottom of the cover 41 to support the bottom of the cover 41.

[0075] The bottom of the pressing part 44 is recessed with a groove. The inner circumference size and shape of the groove are matched with the size and shape of the inner sidewall of the bearing plate 231 so that the upper end of the limiting rod can slide into the groove during operation.

[0076] The outer periphery of the bottom of the pressing member 44 extends outward to form a pressing platform 441 for pressing the stacked stator laminations.

[0077] The cleaning and integration device 6 includes a fixed frame 61, an eighth drive assembly 62, a push plate 64, and a back plate 65. The fixed frame 61 is fixedly mounted on the table surface.

The push plate 64 is fixedly mounted on the output end of the eighth drive assembly 62 to drive the push plate 64 to reciprocate in the horizontal direction of the table surface. A scraper 63 is detachably mounted on the end of the push plate 64 away from the eighth drive assembly 62. A scraper is fixedly mounted on the side of the scraper 63 away from the push plate 64.

[0078] Optionally, a glue groove is formed between the scraper and the scraper 63 to allow the scraped glue to flow down; a glue bucket is fixedly installed on the table below the glue groove to collect the dripping glue; the glue bucket is ring-shaped and is located on the outer periphery of the stacking device 2.

[0079] The scraper is an arc-shaped plate, and the scraper rod 63 is installed and connected to one end of the scraper. An auxiliary rod is fixedly installed on one side of the scraper rod 63. One end of the auxiliary rod is fixedly connected to the side wall of one side of the scraper rod 63, and the other end of the auxiliary rod is installed and connected to the end of the scraper away from the scraper rod 63.

[0080] The curvature of the arc plate is set to match the curvature of the outer periphery of the stator laminations. During operation, the arc plate is attached to the outer periphery of the stator laminations to integrate the stacked stators.

[0081] After the stator laminations are stacked, the eighth drive assembly is activated to drive the scraper to approach the outer periphery of the stacked stator and abut against the outer wall of the stator laminations. The second drive assembly 21 is activated and rotates to the turntable, causing the stator on the carrier plate to rotate synchronously, thereby scraping off the overflowing glue through the scraper.

[0082] The scraper is made of flexible material.

[0083] The feeding device is equipped with a stamping device for stamping the strip material to form stator laminations;

[0084] The feeding device is used to convey the strip material. After the strip material is stamped by the stamping device, the stator sheet is formed but does not fall off the strip material. When the stator sheet is above the predetermined bearing plate 231, the stamping component of the dispensing and blanking device 3 is driven to perform stamping and blanking of the stator sheet.

[0085] The feeding device is equipped with two sets of feeding conveying structures, which are respectively set on both sides of the stacking device 2; the conveying routes of the two sets of feeding conveying structures and the stacking device 2 are axially symmetrical in the horizontal direction.

[0086] Working principle:

[0087] The strip material is conveyed by the feeding conveyor structure at the input end of the stacking device 2 (mounting hole). During the conveying process, the stamping device operates to stamp the strip material to form stator laminations. The stator laminations are conveyed to the top of the bearing plate 231 (mounting hole) of the stacking device 2.

[0088] The dispensing and unloading device 3 is activated and moves horizontally along the table surface to above the stacking station (mounting hole) under the drive of the fifth drive component. The stamping box 34 is driven downward, and the glue application part abuts against the upper surface of the stator sheet, applying the glue on the glue application part to the upper surface of the stator sheet. At the same time, the stamping part is driven by the fourth drive component 35 to punch the stator sheet from the strip onto the carrier plate 231. The carrier plate 23 is driven to rotate by the second drive component 21, and the feeding device continues to transport the next stator sheet, repeating the dispensing and unloading actions. After unloading, the strip continues to be transported as waste by the feeding conveyor structure at the output end of the stacking device. After the stator sheet completes one revolution, the first drive component drives the stacking device 2 to the next end, and the feeding device continues to transport the next stator sheet, repeating the dispensing and unloading actions. Through the continuous rotation of the turntable 22 and the sequential stacking of the stator sheets, a multi-layer stacked stator can be formed.

[0089] After the stator laminations are stacked to a predetermined number of layers, the first drive assembly drives the stacking device 2 to rise, passing through the mounting holes, so that the stacked stator laminations rise above the platform; the sixth drive assembly drives the pressing device 4 to descend; the seventh drive assembly drives the lifting rod to press down the pressing component, directionally pressing the stacked stator to ensure that each layer fits tightly; during the pressing process, a cover is placed on the outer periphery of the stator, and an air cavity is formed between its outer and inner cylinders; the air cavity is connected to external air extraction or heating equipment through an air channel.

[0090] When using anaerobic adhesives, the air extraction device removes the air from the casing, creating a near-oxygen-free environment inside the casing, which accelerates the curing of the anaerobic adhesive.

[0091] When using heated adhesive, the heating device inputs hot air into the casing, and the hot air is evenly applied to the outer periphery of the laminated stator through the through holes on the inner cylinder, thereby accelerating the curing speed of the adhesive.

[0092] Specific embodiment two: Unlike specific embodiment one, it also includes a ninth drive component. A mobile platform is provided below the table of the frame 1. The output end of the first drive component is installed and connected to the mobile platform to drive the mobile platform to move vertically.

[0093] The stacking device 2 is slidably mounted on the top of the mobile platform and can reciprocate between the mobile platform and the table surface; the output end of the ninth drive component is installed and connected to the stacking device 2 to drive the stacking device 2 to reciprocate along the horizontal direction of the mobile platform.

[0094] The table surface is also provided with a through hole running from top to bottom. The through hole is located on one side of the mounting hole. The through hole and the mounting hole are symmetrically arranged at the center. The through hole and the mounting hole are located above the moving path of the stacking device 2 on the moving platform. The feeding device is located on the outer periphery of the through hole. The dispensing device 3 is slidably installed on the outer periphery of the through hole. The stacking device 4 is located above the mounting hole.

[0095] Two sets of feeding conveyor structures are respectively set on both sides of the through hole; the conveying routes of the two sets of feeding conveyor structures and the through hole are arranged axially symmetrically in the horizontal direction.

[0096] The cleaning and integration device 6 is set around the outer periphery of the through hole at intervals.

[0097] Working principle:

[0098] Unlike the first specific embodiment, the stacking device 2 is driven by the ninth driving component to the position of the through hole.

[0099] The strip material is conveyed by the feeding conveyor structure at the input end of the stacking device 2 (through hole). During the conveying process, the stamping device operates to stamp the strip material to form stator laminations. The stator laminations are conveyed to the top of the bearing plate 231 (through hole) of the stacking device 2.

[0100] The dispensing and unloading device 3 is activated and moves horizontally along the table surface to above the stacking station (through hole) under the drive of the fifth drive component. The stamping box 34 is driven downward, and the glue application part abuts against the upper surface of the stator sheet, so that the glue on the glue application part is applied to the upper surface of the stator sheet. At the same time, the stamping part is driven by the fourth drive component 35 to push the stator sheet from the strip onto the carrier plate 231. The carrier plate 23 is driven to rotate by the second drive component 21, and the feeding device continues to transport the next stator sheet, repeating the dispensing and unloading actions. After unloading, the strip is transported by the feeding conveying structure at the output end of the stacking device. After the stator sheet completes one revolution, the first drive component drives the stacking device 2 to the next end, and the feeding device continues to transport the next stator sheet, repeating the dispensing and unloading actions. Through the continuous rotation of the turntable 22 and the sequential stacking of the stator sheets, a multi-layer stacked stator can be formed.

[0101] After the stator laminations are stacked to a predetermined number of layers, the first drive assembly drives the moving platform to descend with the stacking device 2, causing the stacked stator laminations to descend below the platform (through hole); the ninth drive assembly drives the stacking device 2 to move horizontally below the mounting hole, and the first drive assembly drives the stacking device 2 to rise through the mounting hole, causing the stacked stator laminations to rise above the platform; the sixth drive assembly drives the pressing device 4 to descend; the seventh drive assembly drives the lifting rod to press down the pressing component, directionally pressing the stacked stator to ensure that each layer fits tightly; during the pressing process, a cover is placed on the outer periphery of the stator, and an air cavity is formed between its outer and inner cylinders; the air cavity is connected to external air extraction or heating equipment through an air channel.

[0102] When using anaerobic adhesives, the air extraction device removes the air from the casing, creating a near-oxygen-free environment inside the casing, which accelerates the curing of the anaerobic adhesive.

[0103] When using heated adhesive, the heating device inputs hot air into the casing, and the hot air is evenly applied to the outer periphery of the laminated stator through the through holes on the inner cylinder, thereby accelerating the curing speed of the adhesive.

[0104] Specific Embodiment 3: Unlike Specific Embodiment 1 and Specific Embodiment 2, the moving platform under the table is a ring-shaped rotating disk; the output end of the ninth drive component is installed and connected to the rotating disk to drive the rotating disk to rotate.

[0105] Both the stacking device 2 and the first drive assembly are provided in two sets; the output end of the first drive assembly is installed and connected to the corresponding stacking device 2 to drive the corresponding stacking device 2 to reciprocate in the vertical direction.

[0106] Two stacking devices 2 are respectively installed at both ends of the top of the rotating disk; the first drive assembly is respectively installed at the bottom of the rotating disk, and the output end of the first drive assembly passes through the rotating disk and is connected to the corresponding stacking device 2.

[0107] When one set of stacked devices 2 is below the mounting hole, the other set of stacked devices 2 is below the through hole.

[0108] Working principle:

[0109] Unlike Specific Embodiment 2, when one set of stacking devices 2 is below the mounting hole and the other set of stacking devices 2 is below the through hole, the stacking operation of the stator laminations and the pressing operation of the stator laminations after stacking are carried out synchronously, thereby improving production efficiency.

[0110] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
