Description

Technical Field

[0001] The invention relates to the technical field of iron core magnetic steel conveying and assembling, and more specifically, to an iron core magnetic steel conveying and assembling device for a stepping motor. Background Art

[0002] A stepper motor is a control motor that converts electrical pulse signals into angular or linear displacement. The stepper motor core is an important component of the stepper motor. The stepper motor core is usually made of stacked silicon steel sheets and is cylindrical or in other specific shapes. The magnet is used in conjunction with the core, that is, the magnet is the main source of the stepper motor's magnetic field. Assembly equipment is usually used to install the magnet on the stepper motor core by gluing, inlaying or clamping.

[0003] The existing device adopts a magnet pushing method when performing magnet conveying and assembly operations. The magnet is passed through a specific pushing mechanism and is pushed to a specially provided groove on the outer wall of the iron core, so that it fits tightly in the groove. At the same time, the size and shape of the groove on the outer wall of the iron core are adaptively designed to ensure that the magnet can be smoothly embedded therein and maintain a firmly connected state during subsequent use. In addition, due to the use of the magnet pushing method, the existing device can continuously assemble a long iron core with multiple layers of grooves, greatly improving the compatibility of the device.

[0004] However, there are multiple layers of grooves on the outer wall of some long iron cores, and these grooves are in a staggered state, the purpose of which is to make the magnetic field generated by the magnet more uniform and reasonable, thereby improving the performance of the entire device. However, this staggered setting method cannot be used to assemble multiple layers of magnets continuously. In the traditional assembly method, if the grooves are aligned, then multiple layers of continuous assembly can be carried out more smoothly, improving assembly efficiency. However, due to the misalignment of the grooves, during assembly, each layer of magnet requires complex adjustment and positioning operations, and multiple layers cannot be assembled continuously and quickly like the aligned grooves. This greatly reduces the assembly efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide an iron core magnetic steel conveying and assembling device for a stepper motor.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a core magnet conveying and assembly device for a stepper motor, comprising a main body component, two sets of transfer components installed on the top of the main body component, and a first gluing component arranged on the top of the main body component.

[0007] The main component includes a frame, a top plate installed on the top of the frame, and a conveyor belt mechanism installed on one side of the top of the top plate. The two groups of transfer components are arranged on one side of the conveyor belt mechanism, and the two groups of transfer components are staggered. The first glue coating component is arranged between the conveyor belt mechanism and one of the groups of transfer components.

[0008] The first gluing component includes a base installed on the top of the top plate and a driving motor installed inside the base, the output end of the driving motor extends vertically upward and is connected to a rotating shaft, a fixed seat is installed on the top of the top plate and on one side of the base, a first guide rail is vertically installed on the side wall of the fixed seat, two movable seats are slidably connected to the side wall of the first guide rail, and first gluing heads are installed on the side walls of the two movable seats, and the two first gluing heads are both horizontally arranged.

[0009] Four groups of assembly components are installed on the top of the top plate, and a second gluing component is arranged between the four groups of assembly components. A positioning component is installed on the top of the top plate, and one end of the positioning component extends to just above the second gluing component.

[0010] The present invention is further configured as follows: the two groups of the transfer components each include a bracket installed on the top of the top plate and a first electric slide rail horizontally installed on the side wall of the bracket, a transfer cylinder is slidably arranged on the side wall of the first electric slide rail, the piston rod of the transfer cylinder is vertically arranged downward, a bidirectional cylinder is horizontally installed at the end of the piston rod of the transfer cylinder, and the two piston rods of the bidirectional cylinder are both connected with a splint.

[0011] The present invention is further configured as follows: the bottom of each clamping plate is connected to an arc-shaped plate, and arc-shaped grooves are provided on opposite sides of the two arc-shaped plates.

[0012] By adopting the above technical solution, the movable seat drives the corresponding first glue coating head to move, so that the distance between the two first glue coating heads can be adjusted. When the two first glue coating heads apply glue to the two layers of staggered grooves on the outer wall of the iron core, the glue coating gradually decreases when extending from one end of the iron core groove to the middle. When the magnet is inserted into the groove, the magnet first contacts the end with more glue, and then the magnet squeezes the glue and gradually pushes the glue to the end of the groove with less glue, so that the glue is spread out, achieving the effect of covering the magnet and the iron core with glue.

[0013] The present invention is further configured as follows: the second gluing assembly includes a fixing rod installed on the top of the top plate and a connecting plate installed on the top of the fixing rod, four L-shaped plates are equidistantly arranged around the top of the connecting plate, the four L-shaped plates are slidably connected to the top of the connecting plate, and the side wall of each L-shaped plate is horizontally installed with a second gluing head, and the four second gluing heads are arranged corresponding to the four groups of assembly components.

[0014] The present invention is further configured as follows: a slider is installed at the bottom of each L-shaped plate, four groups of second guide rails are installed equidistantly around the top of the connecting plate, the four groups of second guide rails are arranged corresponding to the four L-shaped plates, and the L-shaped plate is slidably connected to the top of the corresponding second guide rail.

[0015] The present invention is further configured as follows: four first sliding grooves are equidistantly arranged around the top of the connecting plate, the four L-shaped plates are arranged corresponding to the four first sliding grooves, and the bottom of each L-shaped plate is connected to a guide column, which is inserted into the corresponding first sliding groove.

[0016] The present invention is further configured as follows: a fixing plate is arranged directly below the connecting plate, the fixing plate is sleeved on the outer side wall of the fixing rod, a positioning motor is installed in the middle of the bottom surface of the fixing plate, the output end of the positioning motor vertically penetrates the fixing plate upward and is connected to a turntable, four second slide grooves are spirally arranged at the bottom of the turntable, the four second slide grooves are arranged corresponding to four guide columns, and the bottom end of the guide column is inserted into the corresponding second slide groove.

[0017] By adopting the above technical solution, the L-shaped plate slides on the top of the connecting plate, thereby driving the corresponding second glue coating head to approach the direction of a corresponding group of assembly components, and the second glue coating head moves to the corresponding position of the magnetic steel side wall inside the conveying track, and the second glue coating head applies glue to the magnetic steel side wall inside the corresponding conveying track, and the magnetic steel gradually moves upward inside the conveying track. The second glue coating head first applies glue to the top of the magnetic steel side wall. During the upward movement of the magnetic steel, the amount of glue applied by the second glue coating head gradually decreases. When the magnetic steel is assembled, the end with more glue fits into the groove of the iron core. As the magnetic steel is gradually installed, the glue is gradually spread out, thereby achieving the effect of replenishing glue and avoiding the lack of glue between the magnetic steel and the iron core.

[0018] The present invention is further configured as follows: the four groups of assembly components are all located on the top of the top plate and are arranged in a surrounding manner, the second glue coating component is arranged at the staggered positions of the four groups of assembly components, each group of assembly components includes a positioning platform installed on the top of the top plate and a feeding track passing through the positioning platform, the feeding track is hollow, a conveying track is vertically arranged on the side of the positioning platform away from the feeding track, the conveying track is connected to the feeding track, a plate body is installed on the side of the positioning platform close to the conveying track, an assembly cylinder is vertically installed on the side wall of the plate body, the piston rod end of the assembly cylinder is connected to the bottom plate, the bottom plate is vertically connected to a push plate on the side wall close to the plate body, and the top of the push plate is inserted into the inside of the conveying track.

[0019] By adopting the above technical solution, the feeding track is used to carry the magnetic steel, that is, the staff can replenish the magnetic steel at any time. Since the magnetic steels are all magnetized, they will be attracted to each other, and a magnet is installed inside the conveying track and at a position horizontal to the feeding track, that is, the front end magnetic steel in the feeding track is attracted by the magnet inside the conveying track, and then the piston rod of the assembly cylinder contracts and pushes the bottom plate and the push plate up, the push plate moves up inside the corresponding conveying track and pushes the front end magnetic steel up, and this magnetic steel is pushed upward from the conveying track, and the groove on the outer wall of the iron core for fitting the magnetic steel is located directly above the conveying track on a set of assembly components. After the magnetic steel is pushed out from the inside of the conveying track, it is directly inserted into the corresponding groove on the outer wall of the iron core, and the bonding is completed using glue applied to the outer wall of the iron core.

[0020] The present invention is further configured as follows: the positioning component includes a support base installed between two groups of assembly components and a second electric slide rail vertically installed on the side wall of the support base, a slide table is slidably connected to the side wall of the second electric slide rail, a rotating cylinder is installed on the top of the slide table, the output end of the rotating cylinder is connected to a fixed block, the fixed block is connected to a supporting plate at a position away from the side wall of the rotating cylinder, one end of the supporting plate away from the fixed block extends to above the second gluing component through the gap between the two groups of assembly components, and a three-jaw chuck is installed on the top of the supporting plate and directly above the second gluing component.

[0021] The present invention is further configured such that: the width of one end of the supporting plate close to the rotating cylinder is the same as the width of the rotating cylinder, and two inclined chamfered surfaces are provided on one end of the supporting plate close to the rotating cylinder, and the width of one end of the supporting plate away from the rotating cylinder is smaller than the width of the gap between the two sets of assembly components.

[0022] By adopting the above technical solution, when the iron core is assembled on the three-jaw chuck, the iron core is located above the three-jaw chuck, and is lowered by the supporting plate and the three-jaw chuck, thereby moving the iron core above the conveying track of the four groups of assembly components. In this state, the four groups of assembly components are all used to assemble the iron core. After completing one assembly, the iron core is rotated by the spacing of a core groove, and then assembled again by the four groups of assembly components, thereby completing the assembly of one layer of magnetic steel.

[0023] Afterwards, the second electric slide rail drives the slide table, rotating cylinder, fixed block, bearing plate and three-jaw chuck to move upward as a whole, so that the iron core moves to a position away from the four groups of assembly components. Then the rotating cylinder drives the fixed block, bearing plate, three-jaw chuck and iron core to flip 180 degrees, with the iron core facing downward, so that the unassembled iron core groove faces the assembly component. Then the iron core drops to the upper position of the four groups of assembly components, and then the magnetic steel is assembled through the assembly component. This operation can realize the magnetic steel assembly operation of the iron core with double-layer misaligned grooves. If the iron core groove has multiple layers, and the multiple layers of grooves are divided into two groups, and the two groups of grooves are misaligned, the magnetic steel assembly can also be performed in this way, that is, after the magnetic steel completes one layer of assembly, the assembly component continues to push the magnetic steel so that the upper layer of non-misaligned grooves can be assembled with magnetic steel. When it is necessary to assemble the magnetic steel for the misaligned groove, the iron core only needs to be flipped and rotated, so that the misaligned groove is opposite to the assembly component, and the assembly component performs the magnetic steel assembly operation on the misaligned groove.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] (1) By setting a positioning component, when the iron core is placed on the three-jaw chuck, the iron core is first assembled with a layer of magnetic steel. Then the second electric slide rail drives the slide table, the rotating cylinder, the fixed block, the load-bearing plate and the three-jaw chuck to move upward as a whole, so that the iron core moves to a position away from the four sets of assembly components. Then the rotating cylinder drives the fixed block, the load-bearing plate, the three-jaw chuck and the iron core to flip 180 degrees, with the iron core facing downward, so that the unassembled iron core groove faces the assembly component. Then the iron core drops to the upper position of the four sets of assembly components, and then the magnetic steel is assembled through the assembly component. This operation can realize the magnetic steel assembly operation of the iron core with double-layer offset grooves.

[0026] (2) The width of one end of the load-bearing plate close to the rotating cylinder is the same as the width of the rotating cylinder, and the width of one end of the load-bearing plate away from the rotating cylinder is less than the width of the gap between the two sets of assembly components. This setting can prevent the load-bearing plate from colliding with the assembly components when flipping and moving, and an inclined chamfered surface is provided at the connection between the load-bearing plate and the fixed block to increase the contact connection surface, thereby improving the connection strength.

[0027] (3) By setting two first glue coating heads, the movable seat drives the corresponding first glue coating heads to move, so that the distance between the two first glue coating heads can be adjusted. When the two first glue coating heads apply glue to the two layers of grooves staggered on the outer wall of the iron core, the glue coating gradually decreases when extending from one end of the iron core groove to the middle. When the magnet is inserted into the groove, the magnet first contacts the end with more glue, and then the magnet squeezes the glue and gradually pushes the glue to the end of the groove with less glue, so that the glue is spread out, achieving the effect of covering the magnet and the iron core with glue.

[0028] (4) By setting up a second glue coating component, the L-shaped plate slides on the top of the connecting plate, thereby driving the corresponding second glue coating head to approach the direction of the corresponding group of assembly components. The second glue coating head moves to the position of the magnetic steel side wall inside the corresponding conveying track, and the second glue coating head applies glue to the magnetic steel side wall inside the corresponding conveying track. The magnetic steel gradually moves upward inside the conveying track. The second glue coating head first applies glue to the top of the magnetic steel side wall. During the upward movement of the magnetic steel, the amount of glue applied by the second glue coating head gradually decreases. When the magnetic steel is assembled, the end with more glue fits with the groove of the iron core. As the magnetic steel is gradually installed, the glue is gradually spread out, thereby achieving the effect of replenishing glue and avoiding the lack of glue between the magnetic steel and the iron core.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0050] See also Figure 1-13 , the present invention provides the following technical solutions:

[0051] Embodiment 1, a core magnetic steel conveying and assembling device for a stepper motor, comprises a main body component 1, the main body component 1 is used to convey the core to facilitate subsequent assembly work, and the specific structure of the main body component 1 is as follows:

[0052] See also Figure 1The main component 1 includes a frame 11, a top plate 13 installed on the top of the frame 11, and a conveyor belt mechanism 12 installed on one side of the top of the top plate 13. Two groups of transfer components 2 are arranged on one side of the conveyor belt mechanism 12. The conveyor belt mechanism 12 is used to transport the iron core. The iron core is transported to the position of one group of transfer components 2. This group of transfer components 2 is used to transfer and transport the transported iron core.

[0053] See also Figure 1 and Figure 5 The specific structure of the transfer component 2 is as follows:

[0054] The two groups of transfer components 2 are staggered, and the two groups of transfer components 2 include a bracket 21 installed on the top of the top plate 13 and a first electric slide rail 22 installed horizontally on the side wall of the bracket 21. The side wall of the first electric slide rail 22 is slidably provided with a transfer cylinder 23. The first electric slide rail 22 can be a stepper motor linear slide rail slide seat module, that is, the stepper motor drives the screw rod on the linear slide rail to rotate, and the slide seat is threadedly connected to the screw rod. When the screw rod rotates, the slide seat slides along the extension direction of the screw rod. The transfer cylinder 23 is connected to the slide seat of the first electric slide rail 22. When the sliding seat of an electric slide rail 22 moves, the transfer cylinder 23 moves synchronously. The piston rod of the transfer cylinder 23 is set vertically downward. A two-way cylinder 24 is horizontally installed at the end of the piston rod of the transfer cylinder 23. The two piston rods of the two-way cylinder 24 are both connected with a clamping plate 25. When the transfer cylinder 23 moves to the end position of the conveyor belt mechanism 12, the piston rod of the transfer cylinder 23 extends and pushes the two-way cylinder 24 to move downward until the clamping plate 25 moves to the outer wall position of the iron core, and then the two-way cylinder 24 drives the two clamping plates 25 to approach each other to clamp the iron core.

[0055] See also Figure 1 and Figure 5 In this embodiment, the bottom of each clamping plate 25 is connected to an arc plate 26, and arc grooves are opened on the opposite sides of the two arc plates 26. When the clamping plate 25 moves, the corresponding arc plates 26 are driven to approach each other, and the arc grooves on the opposite sides of the two arc plates 26 fit with the outer wall of the iron core, thereby grabbing the iron core, and then the iron core is lifted and transferred through the cooperation of the first electric slide rail 22 and the transfer cylinder 23.

[0056] See also Figure 1 and Figure 4 A first glue coating component 3 is installed on the top of the top plate 13. The first glue coating component 3 is used to carry the iron core grabbed from the conveyor belt mechanism 12, that is, the iron core is glued at the position of the first glue coating component 3. The specific structure of the first glue coating component 3 is as follows:

[0057] See also Figure 1 and Figure 4The first glue coating component 3 includes a base 31 installed on the top of the top plate 13, and a driving motor 32 is installed inside the base 31. The output end of the driving motor 32 extends vertically upward and is connected to a rotating shaft 33. The rotating shaft 33 is used to place and position the iron core, and the driving motor 32 can drive the iron core to rotate, thereby adjusting the angle of the iron core.

[0058] See also Figure 1 and Figure 4 A first glue coating head 37 is provided on the side wall of the fixed seat 34. The first glue coating head 37 performs glue coating on the outer wall of the iron core, and the outer wall of the iron core is coated with glue by the continuous rotation of the iron core. The glued iron core is grabbed by another set of transfer components 2 parallel to the conveyor belt mechanism 12 and transferred to the assembly station for magnetic steel assembly.

[0059] See also Figure 1 and Figure 6 , four sets of assembly components 5 are installed on the top of the top plate 13, and a positioning component 6 is installed on the top of the top plate 13. One end of the positioning component 6 extends between the four sets of assembly components 5. The iron core coated with glue is transferred to the position of the positioning component 6, and then the positioning component 6 is assembled with magnetic steel by the four sets of assembly components 5. The specific structure of the assembly component 5 is as follows:

[0060] See also Figure 1-Figure 4 The four assembly components 5 are all located at the top of the top plate 13 and are arranged around. Each assembly component 5 includes a positioning platform 51 installed on the top of the top plate 13 and a feeding track 52 passing through the positioning platform 51. The feeding track 52 is hollow. A conveying track 56 is vertically arranged on the side of the positioning platform 51 away from the feeding track 52. The conveying track 56 is connected to the feeding track 52. A plate body 53 is installed on the side of the positioning platform 51 close to the conveying track 56. An assembly cylinder 54 is vertically installed downward on the side wall of the plate body 53. The piston rod end of the assembly cylinder 54 is connected to a bottom plate 55. A push plate 57 is vertically connected to the side wall of the bottom plate 55 close to the plate body 53. The top of the push plate 57 is inserted into the inside of the conveying track 56. The feeding track 52 is used to carry the magnetic steel, that is, the worker Staff can replenish the magnetic steel at any time. Since the magnetic steels are in a magnetized state, they will be attracted to each other. A magnet is installed inside the conveying track 56 and at a position horizontal to the feeding track 52, that is, the frontmost magnetic steel in the feeding track 52 is attracted by the magnet inside the conveying track 56. Then, the piston rod of the assembly cylinder 54 contracts and pushes the bottom plate 55 and the push plate 57 upward. The push plate 57 moves upward inside the corresponding conveying track 56 and pushes the frontmost magnetic steel upward. This magnetic steel is pushed upward from the conveying track 56, and the groove on the outer wall of the iron core for fitting the magnetic steel is located directly above the conveying track 56 on a set of assembly components 5. After the magnetic steel is pushed out from the inside of the conveying track 56, it is directly inserted into the corresponding groove on the outer wall of the iron core, and the bonding is completed using glue applied to the outer wall of the iron core.

[0061] Afterwards, the positioning assembly 6 drives the iron core to rotate by the spacing of a groove, so that the vacant groove moves to the top of the conveying track 56, and the next magnetic steel continues to perform the fitting and plugging operation. The assembled iron core is grabbed and sent out by an external robot.

[0062] In the second embodiment, the existing device adopts the method of pushing the magnet for assembly, that is, the magnet is pushed into the groove of the outer wall of the iron core to fit into it, and it can be assembled continuously for the long iron core, but the multi-layer grooves on the outer wall of some long iron cores are staggered. The purpose is to make the magnetic field generated by the magnet more uniform and reasonable, but this method cannot perform multi-layer continuous assembly of magnets, which greatly reduces the assembly efficiency.

[0063] See also Figure 1 Therefore, when the core is placed at the position of the positioning assembly 6, the core is first assembled with a layer of magnetic steel, and then the orientation and position of the core are adjusted by the positioning assembly 6, and then the next layer of magnetic steel is assembled. The specific structure of the positioning assembly 6 is as follows:

[0064] See also Figure 6 and Fig.11 In this embodiment, the positioning component 6 includes a support seat 61 installed between two groups of assembly components 5 and a second electric slide rail 62 vertically installed on the side wall of the support seat 61. A slide table 63 is slidably connected to the side wall of the second electric slide rail 62. The second electric slide rail 62 can be a stepper motor linear slide rail slide seat module, that is, the stepper motor drives the screw on the linear slide rail to rotate, and the slide seat is threadedly connected to the screw rod. When the screw rod rotates, the slide seat slides along the extension direction of the screw rod. The slide table 63 is connected to the slide seat of the second electric slide rail 62. When the slide seat of the second electric slide rail 62 moves, the slide table 63 moves synchronously. A rotating cylinder 64 is installed on the top of the slide table 63. The output end of the rotating cylinder 64 is connected to a fixed block 65. The fixed block 65 is connected to a bearing plate 66 at a side wall position away from the rotating cylinder 64. 63 drives the rotating cylinder 64, the fixed block 65 and the supporting plate 66 to move synchronously, and the rotating cylinder 64 can drive the fixed block 65 and the supporting plate 66 to flip, and the end of the supporting plate 66 away from the fixed block 65 extends to the top of the second glue coating component 4 through the gap between the two groups of assembly components 5, and the width of the end of the supporting plate 66 close to the rotating cylinder 64 is the same as the width of the rotating cylinder 64, and the end of the supporting plate 66 close to the rotating cylinder 64 is provided with two inclined chamfered surfaces, and the width of the end of the supporting plate 66 away from the rotating cylinder 64 is less than the width of the gap between the two groups of assembly components 5. This setting can avoid the collision of the supporting plate 66 with the assembly component 5 during flipping and movement, and an inclined chamfered surface is set at the connection between the supporting plate 66 and the fixed block 65 to increase the contact connection surface, thereby improving the connection strength.

[0065] See also Fig.11A three-jaw chuck 67 is installed on the top of the supporting plate 66 and directly above the second glue coating component 4. The three-jaw chuck 67 is used to internally clamp and position the iron core that needs to be assembled with magnetic steel, and the supporting plate 66 drives the three-jaw chuck 67 to move synchronously when moving and flipping. A servo motor is installed below the supporting plate 66, and the output end of the servo motor is connected to the center of the bottom surface of the three-jaw chuck 67, that is, the servo motor drives the three-jaw chuck 67 to rotate on the supporting plate 66.

[0066] When the iron core is assembled on the three-jaw chuck 67, the iron core is located above the three-jaw chuck 67, and is lowered by the supporting plate 66 and the three-jaw chuck 67, thereby moving the iron core above the conveying track 56 of the four groups of assembly components 5. In this state, the four groups of assembly components 5 are all used to assemble the iron core. After completing one assembly, the iron core is rotated by the spacing of a core groove, and then assembled again through the four groups of assembly components 5, thereby completing the assembly of one layer of magnetic steel.

[0067] Then, the second electric slide rail 62 drives the slide 63, the rotating cylinder 64, the fixed block 65, the bearing plate 66 and the three-claw chuck 67 to move upward as a whole, so that the iron core moves up to a position away from the four assembly components 5. Then, the rotating cylinder 64 drives the fixed block 65, the bearing plate 66, the three-claw chuck 67 and the iron core to flip 180 degrees, with the iron core facing downward, so that the unassembled iron core groove faces the assembly component 5. Then, the iron core drops to the upper position of the four assembly components 5, and then the magnetic steel is assembled through the assembly component 5. This operation can be realized. The iron core with double-layer misaligned grooves is now assembled with magnetic steel. If the iron core grooves have multiple layers and the multiple layers of grooves are divided into two groups, and the two groups of grooves are misaligned, the magnetic steel can also be assembled in this way. Specifically, after one layer of magnetic steel is assembled, the assembly component 5 continues to push the magnetic steel so that the upper grooves that are not misaligned can be assembled with magnetic steel. When it is necessary to assemble the magnetic steel for the misaligned grooves, the iron core only needs to be turned over and rotated so that the misaligned grooves are opposite to the assembly component 5, and the assembly component 5 performs the magnetic steel assembly operation on the misaligned grooves.

[0068] In the third embodiment, in order to ensure the stability of the magnets attached to the outer wall of the core, the grooves on the outer wall of the core are all arranged in a trapezoidal structure, that is, the magnets are pushed into the grooves on the outer wall of the core to achieve assembly. For the assembly of magnets on a long core, it is only necessary to push the magnets continuously. However, the push-in assembly method can easily cause the glue to be pushed out, thereby causing the glue to be missing, which affects the assembly stability of the magnets.

[0069] See also Figure 4 and Fig.12To this end, a fixed seat 34 is installed on the top of the top plate 13 and on one side of the base 31. A first guide rail 35 is vertically installed on the side wall of the fixed seat 34. Two moving seats 36 are slidably connected to the side wall of the first guide rail 35. First glue coating heads 37 are installed on the side walls of the two moving seats 36. The two first glue coating heads 37 are both horizontally arranged. The moving seat 36 is composed of a driving motor, a wheel body and a moving platform. The driving motor drives the wheel body to rotate, thereby driving the moving platform to move on the first guide rail 35, thereby adjusting the position of the moving seat 36, and the moving seat 36 drives the corresponding first glue coating head 37 to move. The movement enables the spacing between the two first glue coating heads 37 to be adjusted. Since there are two layers of offset grooves on the outer wall of the iron core, and the magnets are inserted through the opposite ends of the two layers of grooves, when the two first glue coating heads 37 apply glue to the two layers of offset grooves on the outer wall of the iron core, the glue applied gradually decreases when extending from one end of the iron core groove to the middle. When the magnet is inserted into the groove, the magnet first contacts the end with more glue, and then the magnet squeezes the glue and gradually pushes the glue to the end of the groove with less glue, so that the glue is spread out, achieving the effect of covering the magnet and the iron core with glue.

[0070] See also Figure 6 In addition, a second glue coating component 4 is provided between the four assembly components 5. The second glue coating component 4 is provided at the staggered position of the four assembly components 5. The second glue coating component 4 coats the bonding surface of the magnetic steel with glue to avoid the situation where glue is missing between the magnetic steel and the iron core. The specific structure of the second glue coating component 4 is as follows:

[0071] See also Figure 7-Figure 10 The second glue coating component 4 includes a fixing rod 41 installed on the top of the top plate 13 and a connecting plate 46 installed on the top of the fixing rod 41. A fixing plate 42 is arranged directly below the connecting plate 46. The fixing plate 42 is sleeved on the outer wall of the fixing rod 41. A positioning motor 43 is installed in the middle of the bottom surface of the fixing plate 42. The output end of the positioning motor 43 vertically penetrates the fixing plate 42 upward and is connected to a turntable 491. The positioning motor 43 is used to drive the turntable 491 to rotate.

[0072] See also Figure 7-Figure 10In this embodiment, four first sliding grooves 49 are equidistantly provided around the top of the connecting plate 46, and four L-shaped plates 44 are equidistantly provided around the top of the connecting plate 46. The four L-shaped plates 44 are arranged corresponding to the four first sliding grooves 49. The bottom of each L-shaped plate 44 is connected to a guide column 493, which is inserted into the corresponding first sliding groove 49. Four second sliding grooves 492 are spirally provided around the bottom of the rotating disk 491. The four second sliding grooves 492 are arranged corresponding to the four guide columns 493. The bottom ends of the guide columns 493 are inserted into the corresponding second sliding grooves 492. When the rotating disk 491 rotates, the corresponding guide columns 493 are driven to move, and the other ends of the guide columns 493 slide along the corresponding first sliding grooves 49. The rotating disk 491 rotates in the opposite direction, and the corresponding guide columns 493 slide in the opposite direction in the corresponding first sliding grooves 49 and the second sliding grooves 492, and the guide columns 493 drive the corresponding L-shaped plates 44 to move synchronously during the movement.

[0073] See also Figure 7-Figure 10 In this embodiment, a slider 48 is installed at the bottom of each L-shaped plate 44, and four groups of second guide rails 47 are installed equidistantly around the top of the connecting plate 46. The four groups of second guide rails 47 are arranged corresponding to the four connecting plates 46. The connecting plate 46 is slidably connected to the top of the corresponding second guide rail 47. During the movement, the L-shaped plate 44 drives the corresponding slider 48 to slide on the top of the corresponding second guide rail 47, thereby guiding the L-shaped plate 44.

[0074] See also Figure 7-Figure 10 and Fig.13 A second glue coating head 45 is horizontally installed on the side wall of each L-shaped plate 44. The four second glue coating heads 45 are corresponding to the four groups of assembly components 5. During the movement, the L-shaped plate 44 drives the corresponding second glue coating head 45 to approach the direction of the corresponding group of assembly components 5. The second glue coating head 45 moves to the position of the magnetic steel side wall inside the corresponding conveying track 56, and the second glue coating head 45 applies glue to the magnetic steel side wall inside the corresponding conveying track 56. The magnetic steel gradually moves upward inside the conveying track 56. The second glue coating head 45 first coats glue on the top of the magnetic steel side wall. During the upward movement of the magnetic steel, the amount of glue coated by the second glue coating head 45 gradually decreases. When the magnetic steel is assembled, the end with more glue fits with the groove of the iron core. As the magnetic steel is gradually installed, the glue is gradually spread out, thereby achieving the effect of replenishing glue and avoiding the lack of glue between the magnetic steel and the iron core.
