Description

Technical Field

[0001] This application relates to the field of motor rotor assembly technology, and in particular to a motor rotor dispensing machine. Background Technology

[0002] Brushless motors are a common type of motor. They operate by controlling the motor's operation with electronic components, rather than using traditional carbon brushes and commutators. In a brushless motor, the rotor consists of an iron core and a magnetic core. The magnetic core is typically attached to the outer casing or the surface of the iron core, or embedded inside the iron core. These magnetic cores often use strong magnets such as neodymium iron boron or samarium cobalt magnets. Because the rotor is subjected to high-speed rotational forces during operation, adhesive is used to firmly bond the magnetic core to the iron core to ensure stable operation and long-term durability of the motor.

[0003] Among related technologies, Chinese Patent No. CN219232883U discloses an automatic dispensing machine for a motor rotor. Its key technical features include: a frame, and a mechanism for supporting and rotating the rotor. The machine includes a platform, a conveying mechanism for placing or removing a rotor from the platform, a fixing mechanism for pressing down and fixing the rotor, a first dispensing device for applying adhesive to the sidewalls of the rotor, and a second dispensing device for applying adhesive to the bottom of the sidewalls of the rotor. A worktable is provided on the frame. The conveying mechanism is horizontally arranged on the worktable. The platform is arranged beside the conveying mechanism. The fixing mechanism and the first dispensing device are arranged around the platform. The second dispensing device faces the bottom of the platform and is horizontally arranged on the worktable.

[0004] The above-mentioned device can only apply adhesive to the assembled rotor. When the rotor is not fully assembled, the iron core and magnetic core need to be assembled on other equipment first. After the iron core and magnetic core are assembled into a rotor, the rotor is then moved to the above-mentioned dispensing machine for dispensing. Therefore, for rotors that have not been assembled, the above-mentioned device needs to cooperate with other equipment to complete the dispensing process, which is not conducive to improving work efficiency. Summary of the Invention

[0005] To facilitate the dispensing and assembly of unassembled rotors, this application provides a motor rotor dispensing machine.

[0006] The motor rotor dispensing machine provided in this application adopts the following technical solution: A motor rotor dispensing machine includes: a first dispensing device for applying adhesive to the outer periphery of an iron core; an assembly device for assembling a magnetic core and the adhesive-coated iron core; the assembly device includes: a positioning block having a first positioning groove for positioning the magnetic core and a second positioning groove for positioning one end of the iron core; a magnetic core feeding mechanism for placing the magnetic core in the first positioning groove; an iron core feeding mechanism for placing one end of the iron core in the second positioning groove, with the adhesive-coated outer periphery of the iron core fitted onto the inner periphery of the magnetic core; and a conveying mechanism for sequentially conveying the positioning block between the magnetic core feeding mechanism and the iron core feeding mechanism.

[0007] By adopting the above technical solution, the magnetic core feeding mechanism places the magnetic core in the first positioning groove on the positioning block. Then, the conveying mechanism drives the positioning block containing the magnetic core to move to the side close to the iron core feeding mechanism. The first dispensing device applies glue to the outer periphery of the iron core. Then, the iron core feeding mechanism inserts the glued iron core into the second positioning groove, so that the glued end of the iron core is fitted onto the inside of the magnetic core, completing the dispensing and assembly of the iron core and the magnetic core. The working process is more compact, thus helping to improve work efficiency.

[0008] Optionally, the assembly device is configured in two sets, with a flipping device and a second adhesive dispensing device provided between the two sets of assembly devices. The flipping device is used to flip the iron core at a preset angle and place it on the second adhesive dispensing device, which is used to apply adhesive to the outer periphery of the iron core.

[0009] By adopting the above technical solution, the first dispensing device first applies glue to one end of the iron core, and then the assembly device assembles and bonds the magnetic core to the end of the iron core. Next, the flipping device flips the iron core after the first dispensing by 180°, and then the second dispensing device applies glue to the other end of the iron core. Then, the assembly device assembles and bonds the second magnetic core to the end of the iron core, thus completing the assembly of the iron core and the magnetic cores at both ends.

[0010] Optionally, the conveying route of the conveying mechanism is arranged in a loop. Both sets of the conveying mechanisms are provided with a drying side and a feeding side. The conveying mechanism can convey the positioning block to the drying side. The two drying sides are provided with the same drying mechanism. The drying mechanism is used to dry the glue on the iron core. The dried iron core is conveyed to the feeding side by the conveying mechanism.

[0011] By adopting the above technical solution, after the iron core and magnetic core placed in the positioning block complete the dispensing and assembly process, the conveying mechanism transports the assembled iron core to the drying mechanism, thereby drying the glue, accelerating the solidification of the glue, and helping to enhance the bonding and fixing effect of the glue.

[0012] Optionally, the dispensing machine further includes a pressing mechanism for pressing the iron core so that the magnetic core is fitted onto the glue-coated outer periphery of the iron core.

[0013] By adopting the above technical solution, the pressing mechanism can press the iron core downward, thereby pressing the iron core against the magnetic core, which helps to enhance the assembly effect of the iron core and the magnetic core and reduce the possibility of improper assembly of the iron core and the magnetic core.

[0014] Optionally, the positioning block includes a mounting block and a support block. The mounting block has a mounting hole, and the support block is disposed in the mounting hole. The first positioning groove is formed between the end of the support block and the inner wall of the mounting hole. The end of the support block near the first positioning groove is provided with a protrusion for abutting against the end face of the iron core. The second positioning groove passes through the protrusion and extends into the support block. The outer wall of the protrusion and the inner wall of the magnetic core are spaced apart. The end face of the support block and the protrusion located on the same side can abut against the end face of the magnetic core.

[0015] By adopting the above technical solution, the setting of bumps helps to enhance the positioning of iron core and magnetic core; since the outer wall of the bump and the inner wall of the magnetic core are spaced apart, there is a gap between the bump and the magnetic core, which allows the device to adapt to magnetic cores of different sizes and has a wider range of applications.

[0016] Optionally, the protrusion may have a chamfer or rounded corner at the opening of the second positioning groove.

[0017] By adopting the above technical solution, it is easy to insert the end of the iron core into the second positioning groove.

[0018] Optionally, the magnetic core feeding mechanism includes a first feeding component and a first loading component. The first feeding component is used to neatly arrange the magnetic cores and transport them to the loading position of the first loading component. The first loading component is used to feed the magnetic cores into the first positioning groove.

[0019] By adopting the above technical solution, the first feeding component and the first loading component can work together to deliver the magnetic core into the first positioning slot, thus completing the loading process of the magnetic core.

[0020] Optionally, the first feeding assembly includes a support block, a first power telescopic member, and a second power telescopic member. The support block is disposed above the conveying mechanism and has a discharge hole that communicates with the first positioning groove. The movable end of the first power telescopic member is slidably disposed on the support block, and the extension direction of the movable end of the first power telescopic member is arranged radially along the discharge hole. The movable end of the first power telescopic member has a receiving groove for accommodating the magnetic core, and the receiving groove can communicate with the discharge hole. The second power telescopic member is disposed on the side of the discharge hole away from the first positioning groove, and the extension direction of the movable end of the second power telescopic member is parallel to the axis of the discharge hole. The movable end of the second power telescopic member faces the discharge hole.

[0021] By adopting the above technical solution, the first feeding component feeds the magnetic core into the receiving groove, and then the movable end of the first power telescopic component extends to push the magnetic core located in the receiving groove into the upper part of the discharge hole. Then the movable end of the second power telescopic component extends to push the magnetic core downward, so that the magnetic core slides into the first positioning groove after passing through the discharge hole, thereby completing the feeding process of the magnetic core.

[0022] Optionally, the iron core feeding mechanism includes a second feeding component and a second loading component. The second feeding component is used to transport the iron core to a temporary storage station after it is neatly arranged. The second loading component is used to transfer the iron core between the temporary storage station and the first dispensing device, and between the first dispensing device and the conveying mechanism.

[0023] By adopting the above technical solution, the second feeding component and the second loading component can work together to send the iron core into the second positioning slot, thus completing the loading process of the iron core.

[0024] Optionally, the second feeding assembly includes a transfer component and two grippers disposed on the transfer component. The transfer component is used to drive the grippers to move in the horizontal and vertical directions. One of the grippers is used to hold the iron core at the temporary storage station, and the other gripper is used to hold the iron core after one dispensing. The distance between the iron core at the temporary storage station and the iron core on the first dispensing device, the distance between the iron core on the first dispensing device and the iron core on the conveying mechanism, and the distance between the two grippers are equal.

[0025] By adopting the above technical solution, one gripper can transport the un-glued iron core from the temporary storage station to the first gluing device, while the other gripper can transport the glue-coated iron core from the first gluing device to the conveying mechanism. The two transport processes are carried out simultaneously, which can improve the utilization rate of time and help improve work efficiency.

[0026] In summary, this application includes the following beneficial technical effects: 1. First, glue is applied to the iron core on the first dispensing device. At the same time, the magnetic core feeding mechanism sends the magnetic core into the first positioning groove. Then, the conveying mechanism drives the positioning block containing the magnetic core to move to one side of the first dispensing device. Next, the iron core feeding mechanism sends the glued iron core into the second positioning groove, so that the magnetic core is bonded to the outside of the iron core with glue, thereby completing the assembly and dispensing process of the iron core and the magnetic core. The working process is more compact and helps to improve work efficiency.

[0027] 2. After completing the dispensing process of the iron core and the assembly process of the iron core and magnetic core, the conveying mechanism sends the dispensed iron core to the drying mechanism for drying treatment, thereby accelerating the solidification of the glue and helping to enhance the bonding and fixing effect of the glue.

[0028] 3. The conveying route of the conveying mechanism is arranged in a loop, which helps to extend the movement path of the positioning block in the drying mechanism, thereby extending the drying time of the glue and improving the drying effect; in addition, the loop structure can reduce the space occupied by the device and facilitate storage.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0032] This application discloses a motor rotor dispensing machine, which is illustrated using its application in the assembly process of magnetic cores and iron cores as an example. (Refer to...) Figure 1 The magnetic core 1 is ring-shaped, and the iron core 2 includes a cylindrical section 21 and connecting rod sections 22 coaxially fixed to both ends of the cylindrical section 21. The two magnetic cores 1 are respectively sleeved on both ends of the cylindrical section 21 of the iron core 2, and then glued and fixed to form a rotor.

[0033] Reference Figure 2The motor rotor dispensing machine includes a worktable 3, which is vertically oriented and has a horizontal top surface. A first dispensing device 4, a second dispensing device 5, a flipping device 10, and an assembly device are mounted on the top surface of the worktable 3. The first dispensing device 4 and the second dispensing device 5 are spaced apart and used to apply adhesive to the iron core 2 twice. Two sets of assembly devices are provided, one set on one side of the first dispensing device 4 and the other on one side of the second dispensing device 5. The assembly devices are used to insert the adhesive-coated iron core 2 into the inner side of the magnetic core 1, thereby completing the assembly of the iron core 2 and the magnetic core 1. The flipping device 10 is located between the two assembly devices. The flipping device 10 is used to flip the iron core 2, after one dispensing, 180° and place it on the second dispensing device 5, allowing the second dispensing device 5 to apply adhesive to the un-adhesive end of the iron core 2.

[0034] Reference Figure 3 and Figure 4 The first dispensing device 4 includes a mounting base 41, a rotating block 42, a rotary motor 43, a linear motor 44, and a dispensing head 45. The mounting base 41 is fixedly connected to the top surface of the worktable 3; a rotating groove with a circular cross-section is formed on the top surface of the mounting base 41, and the depth direction of the rotating groove is vertical; the rotating block 42 is rotatably disposed in the rotating groove. The rotary motor 43 is fixedly connected to the mounting base 41 by bolts, and the rotary motor 43 is located directly below the rotating block 42; the output shaft of the rotary motor 43 is vertically upward, and the end of the output shaft of the rotary motor 43 is fixedly connected to the bottom wall of the rotating block 42, so the rotary motor 43 can drive the rotating block 42 to rotate. A clamping block 421 is fixedly connected to the top surface of the rotating block 42. The cross-section of the clamping block 421 is fan-shaped. Multiple clamping blocks 421 are arranged in a circumferential array. The clamping block 421 is elastic. A groove 4211 is provided on the inner side of the clamping block 421. After the connecting rod section 22 at the end of the iron core 2 is inserted into the gap between the clamping blocks 421, the wall surface where the groove 4211 of the clamping block 421 is located abuts against the iron core 2, thereby fixing the iron core 2 on the rotating block 42. When the rotating block 42 rotates, it can drive the iron core 2 to rotate synchronously.

[0035] The linear motor 44 is fixedly connected to one side of the mounting base 41 by bolts, and the sliding direction of the movable end of the linear motor 44 is inclined. The dispensing head 45 includes a glue storage tube 451 and a push cylinder 452. The glue storage tube 451 is fixedly connected to the movable end of the linear motor 44 and is arranged along the length direction of the linear motor 44; the glue storage tube 451 stores glue, and one end of the glue storage tube 451 is provided with a glue outlet 4511, which is inclined downward toward the bottom end of the iron core 2 clamped on the clamping block 421. The length direction of the push cylinder 452 is coaxial with the axis of the glue storage tube 451. The push cylinder 452 is fixedly connected to the movable end of the linear motor 44, and the piston rod end of the push cylinder 452 is slidably disposed inside the end of the glue storage tube 451 away from the glue outlet 4511. During the application of adhesive, the linear motor 44 drives the adhesive storage tube 451 to move, causing the adhesive outlet 4511 to move to the side closer to the iron core 2; then, the piston rod of the cylinder 452 is pushed out to squeeze the adhesive in the adhesive storage tube 451 through the adhesive outlet 4511. At the same time, the rotary motor 43 drives the rotating block 42 to rotate, and the rotating block 42 drives the iron core 2 to rotate, thereby applying a ring of adhesive to the outer periphery of the bottom end of the iron core 2.

[0036] Reference Figure 5 The second dispensing device 5 has the same structure as the first dispensing device 4, and will not be described in detail here.

[0037] Reference Figure 6 The assembly device includes a positioning block 6, a conveying mechanism 9, a magnetic core feeding mechanism 7, and an iron core feeding mechanism 8.

[0038] Reference Figure 7 and Figure 8 Multiple positioning blocks 6 are provided, and they are arranged sequentially, end to end. (Refer to...) Figure 9The positioning block 6 includes a mounting block 61 and a support block 62. The mounting block 61 is a rectangular block, and its height direction is vertically oriented. A vertically oriented mounting hole 611 is formed on the mounting block 61, and the mounting hole 611 is a through hole. The support block 62 is cylindrical, and its diameter is the same as the diameter of the mounting hole 611. The support block 62 is fixedly connected inside the mounting hole 611, and the support block 62 abuts against the inner wall of the mounting hole 611. The top of the support block 62 is lower than the top of the mounting block 61. The top of the support block 62 and the side wall of the top of the mounting hole 611 together form a first positioning groove 63, which is used to accommodate the magnetic core 1. A cylindrical protrusion 621 is coaxially fixedly connected to the top wall of the support block 62. The diameter of the protrusion 621 is smaller than the diameter of the support block 62. A second positioning groove 64 is coaxially formed on the protrusion 621. The second positioning groove 64 is a cylindrical groove. The second positioning groove 64 passes through the protrusion 621 and extends into the support block 62, completely penetrating the support block 62. The diameter of the second positioning groove 64 is the same as the diameter of the connecting rod segment 22 of the iron core 2. The second positioning groove 64 is used to accommodate the connecting rod segment 22 of the iron core 2.

[0039] Furthermore, a chamfer 6211 is provided on the protrusion 621 at the opening of the second positioning groove 64, which facilitates the insertion of the connecting rod section 22 of the iron core 2 into the second positioning groove 64.

[0040] Reference Figure 6 The conveying mechanism 9 includes a guide frame 91 and a conveying cylinder 92. The guide frame 91 is fixedly connected to the top surface of the worktable 3, and its length direction is horizontal. A rectangular annular groove 911 is formed on the top surface of the guide frame 91; two rows of positioning blocks 6 are arranged, each row including multiple positioning blocks 6 that abut against each other, and the two rows of positioning blocks 6 are slidably arranged on both sides of the annular groove 911; only two positioning blocks 6 are arranged at each end of the annular groove 911 in the length direction, and the length of the groove at the end of the annular groove 911 in the length direction is more than twice the length of the positioning block 6, so that there is enough gap in the annular groove 911 for the positioning blocks 6 to slide. The conveying cylinder 92 is fixedly connected to the top surface of the worktable 3, and four conveying cylinders 92 are arranged, respectively at the four corners of the guide frame 91. Four through holes 912 are provided on the side wall of the guide frame 91, and each through hole 912 corresponds to one of the four conveying cylinders 92. A push rod 921 is fixedly connected to the piston rod end of the conveying cylinder 92 along its own length direction. The end of the push rod 921 away from the conveying cylinder 92 slides through the corresponding through hole 912. The push rod 921 can push the positioning block 6 in the guide frame 91 to move along the length or width direction of the guide frame 91. Under the joint action of the four conveying cylinders 92, the positioning block 6 can move in a clockwise direction.

[0041] Reference Figure 7 and Figure 8The magnetic core feeding mechanism 7 includes a first feeding assembly 71 and a first feeding assembly 72. The first feeding assembly 71 is a vibratory feeder mounted on the top surface of the workbench 3. The first feeding assembly 72 includes a support block 721 and a first power telescopic member 722. The support block 721 is fixedly connected to the top wall of the guide frame 91 near one end of the first feeding assembly 71; the support block 721 has a horizontal clearance hole 7212 and a vertical dropping hole 7211, which are connected. The diameter of the dropping hole 7211 is the same as the diameter of the first positioning groove 63. The dropping hole 7211 can be positioned directly above the first positioning groove 63, and the dropping hole 7211 and the first positioning groove 63 are coaxially arranged, so that the magnetic core 1 moved into the dropping hole 7211 can fall into the first positioning groove 63 through the dropping hole 7211. The depth direction of the clearance hole 7212 is arranged radially along the discharge hole 7211; the first power telescopic component 722 is a cylinder, and the first power telescopic component 722 is fixedly connected to the top surface of the workbench 3 by bolts. The piston rod end of the first power telescopic component 722 is fixedly connected to a connecting plate 7221 along its own length direction. The connecting plate 7221 slides through the clearance hole 7212; the end of the connecting plate 7221 is provided with a receiving groove 7222 for accommodating the magnetic core 1; under normal conditions, the piston rod of the first power telescopic component 722 is not extended, and the receiving groove 7222 is located at the discharge end of the first feeding assembly 71.

[0042] After the first feeding assembly 71 arranges the magnetic cores 1 neatly, it sends them to the discharge end. Then, the outermost magnetic core 1 is sent into the receiving groove 7222. Next, the piston rod of the first power telescopic member 722 extends, causing the connecting plate 7221 to slide until the receiving groove 7222 on the connecting plate 7221 slides to the state of being aligned with the dropping hole 7211 on the support block 721. At this time, the magnetic core 1 in the receiving groove 7222 can fall into the first positioning groove 63 through the dropping hole 7211, thereby completing the feeding process of the magnetic core 1.

[0043] Furthermore, to reduce the possibility of the magnetic core 1 being stuck in the receiving groove 7222 or the discharge hole 7211 during the feeding process, refer to Figure 8 The first feeding assembly 72 also includes a second power telescopic component 723. The second power telescopic component 723 is a cylinder, fixedly connected to the top wall of the support block 721. The piston rod of the second power telescopic component 723 points vertically downwards, and a push column 7231 is fixedly connected to the end of the piston rod along its length. The push column 7231 and the discharge hole 7211 are coaxially arranged. Therefore, when the receiving groove 7222 on the connecting plate 7221 moves to a state aligned with the discharge hole 7211, the second power telescopic component 723 drives the push column 7231 downwards, which in turn pushes the magnetic core 1 within the receiving groove 7222 downwards, thus ensuring the smooth feeding process of the magnetic core 1.

[0044] Reference Figure 6 The iron core feeding mechanism 8 includes a second feeding assembly 81 and a second feeding assembly 82. The second feeding assembly 81 includes a vibratory feeder mounted on the top surface of the workbench 3. A temporary storage block 811 is provided at the discharge end of the second feeding assembly 81, and the temporary storage block 811 is fixedly connected to the top of the workbench 3. A strip groove 8111 is provided on the top surface of the temporary storage block 811 for accommodating uncoated iron cores 2. The second feeding assembly 82 includes a transfer component 821 and a gripper. The transfer component 821 includes a horizontal cylinder 8211 and a vertical cylinder 8212; the horizontal cylinder 8211 is fixedly connected to the top surface of the workbench 3, and the extension and retraction direction of the piston rod of the horizontal cylinder 8211 is arranged along the width direction of the guide frame 91; the vertical cylinder 8212 is fixedly connected to the end of the piston rod of the horizontal cylinder 8211, and the piston rod of the vertical cylinder 8212 points vertically downward. The gripper is fixedly connected to the piston rod end of the vertical cylinder 8212; there are two grippers, and the two grippers are spaced apart along the length of the horizontal cylinder 8211. The gripper is the first finger cylinder 822, and the two output ends of the gripper can clamp the connecting rod section 22 at the top of the iron core 2 by bringing them close together.

[0045] The spacing between the iron core 2 on the temporary storage block 811 and the iron core 2 on the rotating block 42, the spacing between the iron core 2 on the rotating block 42 and the iron core 2 on the positioning block 6, and the spacing between the two grippers are all equal. Therefore, when one gripper transfers the uncoated iron core 2 between the temporary storage block 811 and the rotating block 42, the other gripper can transfer the iron core 2 after one coat of glue between the rotating block 42 and the positioning block 6. The two transfer processes are carried out simultaneously, which helps to improve work efficiency.

[0046] In addition, in the assembly device near the second dispensing device 5, the distance between the iron core 2 on the second dispensing device 5 and the iron core 2 on the guide frame 91 is equal to the distance between the two grippers. Therefore, when one gripper picks up the iron core 2 after the second dispensing, the other gripper can pick up the iron core 2 after dispensing and assembly, so that the two transfer processes are carried out simultaneously, improving work efficiency.

[0047] Reference Figure 6 The flipping device 10 includes a rotary cylinder 101 and a second finger cylinder 102. The rotary cylinder 101 is fixedly connected to the top surface of the workbench 3 by bolts, and the rotation axis of the output end of the rotary cylinder 101 is parallel to the length direction of the guide frame 91. The second finger cylinder 102 is fixedly connected to the output end of the rotary cylinder 101, and the sliding direction of the two output ends of the second finger cylinder 102 is set along the length direction of the guide frame 91. Therefore, under the combined action of the rotary cylinder 101 and the second finger cylinder 102, the iron core 2 after the first dispensing can be clamped, and then the iron core 2 can be flipped 180° and placed on the second dispensing device 5 for a second dispensing.

[0048] To enhance the assembly effect between iron core 2 and magnetic core 1 and reduce the possibility of improper assembly, refer to Figure 6 A pressing mechanism 12 is provided on the guide frame 91 at the end of the gripper away from the support block 721. The pressing mechanism 12 includes a support 121 fixedly connected to the guide frame 91 and a pressing cylinder 122 fixedly connected to the support 121. The pressing cylinder 122 is located directly above the guide frame 91, and the piston rod end of the pressing cylinder 122 is vertically downward. The piston rod end of the pressing cylinder 122 can be directly facing the iron core 2 placed on the positioning block 6. When the piston rod of the pressing cylinder 122 extends, it can press the connecting rod section 22 at the top of the iron core 2, thereby making the iron core 2 and the bottom magnetic core 1 more compactly assembled and improving the assembly effect.

[0049] In addition, refer to Figure 6 Each guide frame 91 within the two conveying mechanisms 9 includes a drying side 913 and a feeding side 914. The drying side 913 is located at the end furthest from the vibratory feeder, and the feeding side 914 is located at the end closest to the vibratory feeder. A drying mechanism 11 is installed on the top surface of the worktable 3. The drying mechanism 11 is an oven, which contains a fan and a heater. The oven cover is located outside the drying side 913 of the two guide frames 91. During operation, the fan and heater are activated, and hot air circulates inside the oven, thereby heating and drying the glue that moves onto the iron core 2 inside the oven, accelerating the solidification of the glue, and thus enhancing the bonding and fixing effect on the magnetic core 1.

[0050] The workbench 3 is also equipped with a CNC module 13, which is electrically connected to each power component, so that each action process is carried out in an orderly manner.

[0051] The implementation principle of a motor rotor dispensing machine according to an embodiment of this application is as follows: The first feeding component 71 feeds the magnetic core 1 into the receiving groove 7222 on the connecting plate 7221. Then, the piston rod of the first power telescopic component 722 extends and pushes the connecting plate 7221 to move. The connecting plate 7221 pushes the magnetic core 1 to move until the magnetic core 1 moves directly above the discharge hole 7211. Then, the piston rod of the second power telescopic component 723 extends and pushes the magnetic core 1 into the first positioning groove 63, completing the loading of the magnetic core 1. Then, the piston rods of the second power telescopic component 723 and the first power telescopic component 722 reset. Then, the piston rods of the four conveying cylinders 92 extend, so that the positioning block 6 moves clockwise in the guide frame 91. The positioning block 6 with the magnetic core 1 moves from the magnetic core loading mechanism 7 to the iron core loading mechanism 8.

[0052] The second feeding assembly 81 feeds the iron core 2 onto the temporary storage block 811. Then, with the cooperation of the horizontal cylinder 8211 and the vertical cylinder 8212, one of the grippers moves above the temporary storage block 811 and picks up the uncoated iron core 2 on the temporary storage block 811. The iron core 2 is then transported to the rotating block 42 in the first dispensing device 4. Then, the linear motor 44 drives the glue storage tube 451 to move, so that the glue outlet 4511 moves to the side near the bottom of the iron core 2. Then, the piston rod of the cylinder 452 is pushed out, and the glue in the glue storage tube 451 is squeezed out through the glue outlet 4511. At the same time, the rotary motor 43 drives the rotating block 42 to rotate, and the rotating block 42 drives the iron core 2 to rotate, thereby applying a ring of glue to the outer circumference of the bottom of the iron core 2.

[0053] While one gripper is feeding the un-glued iron core 2 onto the rotating block 42, the other gripper can feed the iron core 2, which has been coated with glue once, onto the rotating block 42 into the positioning block 6 in the guide frame 91. This allows the connecting rod segment 22 at the bottom of the glued iron core 2 to be inserted into the second positioning groove 64, and the glue on the periphery of the bottom of the iron core 2 to be bonded and fixed to the inner wall of the magnetic core 1. Then, the positioning block 6, which contains the iron core 2 and the magnetic core 1, moves to the pressing mechanism 12. The piston rod of the pressing cylinder 122 extends downward to press the iron core 2, thereby enhancing the assembly effect of the iron core 2 and the magnetic core 1.

[0054] Then, after being pressed together, the iron core 2 and the magnetic core 1 move into the oven along with the positioning block 6. The hot air circulating in the oven accelerates the solidification of the glue. As the positioning block 6 moves clockwise, the dried positioning block 6 is removed from the oven and then moved to the position of the flipping device 10.

[0055] The second finger cylinder 102 clamps the dried iron core 2, and then the rotary cylinder 101 drives the iron core 2 to rotate 180° through the second finger cylinder 102, so that the magnetic core 1 fixed on the iron core 2 is located at the upper end of the iron core 2, and at the same time the iron core 2 is inserted into the rotating block 42 on the second dispensing device 5. Then the above dispensing, feeding, assembly, pressing and drying process is repeated. After drying, the iron core 2, which has completed the second dispensing, is sent to the storage area by the transfer component 821 and the gripper for storage.

[0056] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
