Abstract

This invention discloses an automatic assembly machine for cylindrical rotor permanent magnets based on exudative adhesive application. The assembly machine includes a base, a motion mechanism, a rotor positioning seat, a centrally located exudative adhesive application device, vertically lifting lower and upper platforms, a magnetic sheet positioning assembly, and a transport clamp. Uniform adhesive exudation is achieved through a microporous array adhesive surface (covered with a polypropylene anti-stick film), with adhesive layer thickness fluctuations controlled within ±5μm. A ring conveyor belt synchronously drives the rotor positioning seat and the adhesive application device, seamlessly connecting the adhesive application and magnetization processes. The magnetic sheet positioning assembly integrates adsorption and pressing functions, precisely pressing the magnetic sheet onto the rotor yoke after adsorption by negative pressure. Combined with the precise alignment of the magnetic sheet guide groove and the guide seat groove, and the coaxial pressing mechanism of the push rod, the radial offset rate of the magnetic sheet is reduced. This invention solves the problems of uneven adhesive layer, process dispersion, and positioning inaccuracy in traditional processes, shortens the assembly cycle of a single rotor, improves the yield rate, and reduces the frequency of equipment downtime maintenance, making it particularly suitable for the manufacturing of high-precision servo motor rotors.

Description

Technical Field

[0001] This invention relates to the field of permanent magnet motor production equipment technology, specifically a cylindrical rotor permanent magnet automatic assembly machine that realizes automated assembly of magnetic sheet gluing, positioning and pressing. Background Technology

[0002] In the manufacturing process of permanent magnet motor rotors, the bonding quality between the permanent magnets (usually neodymium iron boron magnets) and the rotor yoke directly affects the electromagnetic performance and mechanical reliability of the motor. Traditional assembly processes commonly employ needle-type dispensing technology, which has inherent drawbacks: the needle tip is affected by fluctuations in adhesive viscosity and air pressure stability, easily leading to uneven adhesive layer thickness, and adhesive breaks or localized accumulation often occur at the edges of the magnets, resulting in decreased bonding strength. More seriously, epoxy resin adhesive easily adheres to the metal dispensing head, forcing frequent production line shutdowns for cleaning, with an average efficiency loss exceeding 20%. Meanwhile, existing equipment often separates the adhesive application and magnet bonding processes—the dispensing equipment first applies adhesive to the rotor slots, and then a robotic arm transfers the magnets for pressing. This discrete process not only generates cumulative errors due to repetitive positioning but also prolongs the assembly cycle of a single rotor, becoming a bottleneck for capacity improvement.

[0003] The magnetic sheet positioning process also faces technical challenges. Traditional pneumatic pressing mechanisms rely on unidirectional force application, which can easily lead to radial misalignment of the magnetic sheet when it is embedded in the rotor slot. This misalignment not only causes the rotor to exceed dynamic balance limits but also results in adhesive overflow and contamination of the iron core. These issues have collectively caused the rotor product yield to stagnate in the 82%~85% range for a long time. In high-precision applications (such as servo motors), additional manual calibration is even required, significantly increasing manufacturing costs. To address these systemic defects, an integrated solution is needed that can ensure adhesive uniformity and magnetic sheet positioning accuracy while achieving seamless integration of the adhesive application and magnetic bonding processes. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application proposes an automatic assembly machine for cylindrical rotor permanent magnets based on exudative adhesive coating. This application employs micro-pore array adhesive coating, and the components can achieve synchronous driving and precision positioning system to realize automatic adhesive coating and magnetization. It solves the problems of uneven adhesive layer, process dispersion and positioning inaccuracy in traditional processes, and significantly improves assembly accuracy and efficiency.

[0005] The technical solution adopted in this invention is as follows: An automatic assembly machine for cylindrical rotor permanent magnets based on exudative adhesive coating includes: The base is equipped with a motion mechanism that carries and modifies the positions of the glue application equipment and the rotor positioning seat, moving the glue application equipment and the rotor positioning seat to or out of the workstation. The adhesive coating equipment includes a support part and an adhesive coating part. The support part is fixed on the motion mechanism, and the adhesive coating part is detachably installed on the top of the support part. The adhesive coating part has several adhesive coating surfaces arranged in a circumferential array, and the adhesive coating surfaces are densely covered with micropore arrays and polypropylene film. The rotor positioning seat is used to place the rotor yoke to be magnetized; The upper platform is fixedly installed on the upper part of the workstation. Several magnetic sheet guide slots are opened on the upper surface of the upper platform and arranged in an array around the center point for pre-storing magnetic sheets. The outer end of the magnetic sheet guide slot is equipped with an external cylinder. The guide seat is fixedly installed at the upper part of the center of the upper platform. There is a magnetic sheet through hole between the inner end of each magnetic sheet guide groove and the bottom of the guide seat. The magnetic sheet through holes are arranged in a ring. A push rod is movably mounted on the upper part of the guide seat, with the end of the push rod facing the through hole of the magnetic sheet; The lower platform is movably installed between the upper platform and the adhesive application equipment. A magnetic sheet positioning assembly is set at the center of the lower platform. The magnetic sheet positioning assembly includes an annular magnetic sheet positioning seat. The magnetic sheet positioning seat has magnetic sheet placement slots arranged in an array on its circumferential wall surface. The magnetic sheet placement slots are arranged opposite to the magnetic sheet through holes. A magnetic sheet positioning piece is arranged opposite to each magnetic sheet placement slot. The magnetic sheet positioning piece is equipped with a radial moving mechanism to realize the squeezing and separation action of the magnetic sheet by the magnetic sheet positioning piece.

[0006] Furthermore, the support section and the glue application section are equipped with glue delivery pipes that are connected to the external glue supply unit.

[0007] Furthermore, the pore size of the micropore array on the coated surface is 50-100μm.

[0008] Furthermore, the push rod is equipped with a top cylinder, which performs a vertical reciprocating motion relative to the guide seat under the action of the top cylinder.

[0009] Furthermore, the motion mechanism adopts a conveyor belt, and two rotor positioning seats and one glue applicator are fixedly installed on the conveyor belt. The two rotor positioning seats are located on both sides of the glue applicator. Through the reciprocating motion of the conveyor belt, the glue applicator or one of the rotor positioning seats on one side is moved to the work station.

[0010] Furthermore, the adhesive coating equipment is equipped with a linear reciprocating motion mechanism that moves to the workstation in a linear reciprocating motion; while the rotor positioning seat is equipped with a motion mechanism that rotates along an arc-shaped track, with multiple rotor positioning seats arranged in an arc-shaped array.

[0011] Furthermore, the lower platform is installed directly below the upper platform via a linear guide rail and is driven to lift vertically by a motor.

[0012] Furthermore, it is equipped with a transport clamp, which is used for loading magnetic sheets and gripping rotor yokes.

[0013] Furthermore, the transport clamp is located at the corner of the platform, and both its horizontal and vertical arms are telescopic structures, with the clamping end supporting 360° full circumferential rotation.

[0014] Furthermore, by replacing the adhesive coating section with a corresponding number of adhesive coating surfaces, it is applicable to magnetizing cylindrical rotor permanent magnets of different specifications.

[0015] The beneficial effects of this invention are: (1) This invention can significantly improve the quality of the adhesive layer and the reliability of the bond. This invention adopts a microporous array exudation coating technology, combined with a polypropylene anti-sticking film, to achieve uniform coating of epoxy resin on the surface of the magnetic sheet, and precisely control the thickness fluctuation of the adhesive layer within ±5μm. This fundamentally solves the problem of uneven bonding strength caused by adhesive layering or accumulation in traditional dispensing processes, and ensures a firm and stable bond between the magnetic sheet and the rotor yoke.

[0016] (2) The present invention can achieve extremely high magnetic sheet positioning and pressing accuracy. The magnetic sheet positioning assembly is equipped with a radial movement mechanism. The cylinder can integrate negative pressure adsorption and precise pressing functions. With the precise alignment of the magnetic sheet guide groove and the guide seat groove and the coaxial pressing mechanism of the push rod, the radial displacement of the magnetic sheet during the pressing process is effectively suppressed, which greatly improves the dynamic balance performance of the rotor and meets the manufacturing requirements of high-precision servo motor.

[0017] (3) This invention can significantly improve the overall yield and equipment stability. The synergistic improvement in the uniformity of the adhesive layer, the continuity of the process, and the positioning accuracy significantly improves the final assembly yield of the rotor products. At the same time, the polypropylene anti-stick film used on the key contact surfaces effectively prevents the adhesive from sticking to the equipment, reduces the frequency of downtime due to cleaning and maintenance, and improves the continuous operation stability and utilization rate of the equipment.

[0018] (4) The present invention reduces the overall manufacturing cost. The automation and integration design of the present invention reduces the reliance on manual operation, the high yield reduces the loss of scrap, and the improved equipment stability reduces maintenance costs. Especially in high-precision application scenarios, it avoids the expensive manual calibration process, thereby significantly reducing the overall manufacturing cost of permanent magnet motor rotors.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0033] Combined with appendix Figures 1 to 12 As shown, this application proposes an automatic assembly machine for cylindrical rotor permanent magnets based on exudative adhesive coating, including an assembly machine body and a transport clamp 2. The main body of the assembly machine includes a base 1, a rotor positioning seat 3, an adhesive applicator 4, a lower platform 5, a magnetic plate positioning assembly 6, an upper platform 7, a guide seat 8, and a push rod 9. The base 1 is equipped with a motion mechanism, which is used to change the position of the adhesive applicator 4 and the rotor positioning seat 3, and move the adhesive applicator 4 or the rotor positioning seat 3 to the work station.

[0034] The adhesive application equipment 4 includes a support unit and an adhesive application unit. The bottom of the support unit is fixed to the motion mechanism, and its interior is equipped with an adhesive delivery pipe 401 connected to an external adhesive supply unit. The adhesive application unit is detachably mounted on the top of the support unit. The adhesive application unit has several adhesive application surfaces 402 arranged in a circumferential array. The adhesive application surfaces 402 are densely covered with a micropore array (pore size 50-100μm), and the adhesive application surfaces 402 are covered with an extremely thin polypropylene film. Through the design of the micropore array and the polypropylene film, it is possible to ensure uniform adhesive penetration and completely prevent epoxy resin from adhering to the metal surface of the equipment, thereby achieving highly uniform coating with adhesive layer thickness fluctuation ≤ ±5μm.

[0035] The rotor positioning seat 3 is used to place the rotor yoke iron to be magnetized.

[0036] The upper platform 7 is fixedly installed on the upper part of the workstation by a support component (such as a number of support columns arranged in an array); a number of magnetic sheet guide grooves 701 arranged in an array around the center point are opened on the upper surface of the upper platform 7; an external cylinder 702 is equipped at the outer end of the magnetic sheet guide groove 701; multiple magnetic sheets are pre-stored in the magnetic sheet guide groove 701, and the magnetic sheets are pushed towards the center under the action of the external cylinder 702.

[0037] The guide seat 8 is fixedly installed on the upper part of the upper platform 7 at the center. There is a magnetic sheet through hole between the inner end of each magnetic sheet guide groove 701 and the bottom of the guide seat 8. The magnetic sheet through holes are arranged in a ring. The magnetic sheet can leave the upper platform 7 through the through hole. Guide holes are arrayed on the upper part of the guide seat 8, and the guide holes are arranged opposite to the magnetic sheet through holes below.

[0038] A push rod 9 is movably mounted on the upper part of the guide seat 8. The push rod 9 is inserted into the guide seat 8 through the guide hole and faces the magnetic sheet through hole. Under the action of the top cylinder 10, the push rod 9 reciprocates vertically relative to the guide seat 8.

[0039] The lower platform 5 is movably installed below the upper platform 7, moving between the upper platform 7 and the adhesive application equipment 4. A magnetic sheet positioning assembly 6 is located at the center of the lower platform 5. The magnetic sheet positioning assembly 6 includes a magnetic sheet positioning seat 601 and a magnetic sheet positioning piece 602. The magnetic sheet positioning seat 601 has a ring-shaped structure with magnetic sheet placement slots arrayed along its circumferential wall. Each magnetic sheet placement slot of the magnetic sheet positioning seat 601 corresponds one-to-one with the magnetic sheet through holes, guide holes, and push rods 9 arranged in a ring on its upper part. A magnetic sheet positioning piece 602 is positioned opposite each magnetic sheet placement slot. The magnetic sheet positioning piece 602 is equipped with a radial movement mechanism, which can drive the magnetic sheet positioning piece 602 to move radially to compress the magnetic sheet or to separate it from the magnetic sheet.

[0040] In this embodiment, the radial movement mechanism uses a small cylinder 501 and a cylinder, which are located inside the lower platform 5. The small cylinder 501 is located at one end of the cylinder, and the magnetic positioning plate 602 is movably installed within the cylinder. When the small cylinder 501 inflates the cylinder, it pushes the magnetic positioning plate 602 towards the center to compress the magnetic plate. When the small cylinder 501 extracts air from the cylinder, the negative pressure attracts the magnetic positioning plate 602 away from the center, causing it to separate from the magnetic plate. Alternatively, the small cylinder 501 and the magnetic positioning plate 602 can be fixed and movably installed within the cylinder. When the small cylinder 501 inflates the cylinder, it pushes both the small cylinder 501 and the magnetic positioning plate 602 towards the center simultaneously to compress the magnetic plate. When the small cylinder 501 extracts air from the cylinder, the negative pressure attracts both the small cylinder 501 and the magnetic positioning plate 602 away from the center, causing them to separate from the magnetic plate.

[0041] In this embodiment, in addition to the cylinder design, the radial movement mechanism can also adopt a design that connects the hydraulic push rod and the magnetic plate positioning plate 602 to realize the movement of the magnetic plate positioning plate 602 moving closer to and away from the magnetic plate.

[0042] In this embodiment, to accommodate different specifications of cylindrical rotor permanent magnets, the coating section with a corresponding number of coating surfaces 402 can be replaced. The coating section shown in this embodiment has a design with 8 coating surfaces 402. By replacing the coating section, designs with different numbers or sizes of coating surfaces 402 can be obtained.

[0043] In this embodiment, the motion mechanism adopts a conveyor belt, and two rotor positioning seats 3 and one glue applicator 4 are fixedly installed on the conveyor belt. The two rotor positioning seats 3 are located on both sides of the glue applicator 4. By the reciprocating motion of the conveyor belt, the glue applicator 4 or one of the rotor positioning seats 3 on one side can be moved to the work station.

[0044] In this embodiment, in addition to using a conveyor belt, the gluing equipment 4 can be equipped with a reciprocating motion mechanism that can move along a straight line, such as a transversely arranged slide rail or telescopic rod design, so that the gluing equipment 4 moves back and forth along a straight line to the work station; while the rotor positioning seat 3 is equipped with a motion mechanism that rotates along an arc track, so that more rotor positioning seats 3 and rotor yokes to be magnetized can be set up in batches. When the gluing equipment 4 leaves the work station, the rotor positioning seat 3 rotates to the work station; and so on.

[0045] In this embodiment, the lower platform 5 is installed directly below the upper platform 7 via a linear guide rail and can be vertically lifted by a motor.

[0046] In this embodiment, the top cylinder 10 is installed above the upper platform, and its piston rod is connected to the push rod 9. The push rod 9 passes through the through hole in the center of the guide seat 8 and is coaxially arranged with the magnetic plate positioning assembly 6.

[0047] In this embodiment, the transport clamp 2 is located at the corner of the platform, and both its horizontal and vertical arms are telescopic structures. The clamping end supports 360° full-circumference rotation, used for synchronously transporting pre-arranged neodymium iron boron magnets to the magnet guide groove 701 of the upper platform 7, and to the rotor yoke to the rotor positioning seat 3. To achieve fully automatic and high-precision operation of this assembly machine, the system is equipped with a central control unit based on a programmable logic controller (PLC). The controller is connected to the following actuators via electrical wiring, including but not limited to: Conveyor belt drive motor (used to move the glue application equipment 4 and rotor positioning seat 3).

[0048] The lower platform lifting motor (drives the lower platform 5 to move vertically along the linear guide rail).

[0049] The glue supply unit inside the glue application equipment (controls the glue flow and on / off).

[0050] External cylinder 702 (pushes the magnetic sheet to move towards the center along the magnetic sheet guide groove 701).

[0051] Top cylinder 10 (drives push rod 9 to move up and down).

[0052] The drive motor of the small cylinder 501 (drives the magnetic positioning plate 602 to move horizontally).

[0053] Servo motor of transport clamp 2 (controlling its multi-degree-of-freedom movement).

[0054] Meanwhile, the system deploys sensors at various key locations, including but not limited to: Position sensor (detects the real-time position of the glue application equipment 4, rotor positioning seat 3, and lower platform 5).

[0055] Pressure sensor (monitors the pressure of magnetic positioning plate 602 on magnetic sheet during the pressing process).

[0056] Adhesive level sensor (monitors the amount of adhesive in the adhesive supply unit).

[0057] The controller has pre-set assembly programs for rotors of different specifications, including process parameters such as the action sequence of each mechanism, running time, displacement, and pressure threshold. Operators can select rotor specifications, adjust parameters, and monitor operating status through a human-machine interface (HMI).

[0058] Combination Figure 12 The complete workflow diagram systematically illustrates the fully automated operation process from material loading to rotor finished product unloading: S1 Loading Stage: The magnetic sheets are loaded into the magnetic sheet guide slots 701 of the upper platform 7 using the transport clamp 2. The magnetic poles (N pole and S pole) of the magnetic sheets in adjacent magnetic sheet guide slots 701 are arranged alternately along the circumference of the rotor. The rotor yoke is then installed onto the rotor positioning seat 3 using the transport clamp 2.

[0059] S2. Loading and Pre-positioning: The gluing equipment 4 moves to the workstation, and the lower platform 5 moves up to contact the bottom of the upper platform 7; the external cylinder 702 is activated to push the magnetic sheet in the magnetic sheet guide groove 701 towards the center; then the top cylinder 10 drives the push rod 9 to move downward, pressing down the moving magnetic sheet, which falls through the magnetic sheet through hole into the magnetic sheet placement groove of the lower magnetic sheet positioning seat 601; then the push rod 9 can be reset, the external cylinder 702 stops moving, and the magnetic sheet is picked up.

[0060] S3, Glue application stage: The lower platform 5 carries the magnetic sheet downward until the glue application device 4 is inserted into the magnetic sheet positioning seat 601. The exudative glue application device 4 is started, and the glue forms a uniform glue layer on the inner surface of the magnetic sheet through the micropore array. Then the lower platform 5 moves upward, so that the magnetic sheet positioning seat 601 is separated from the glue application device 4.

[0061] S4. Magnetic Sheet and Rotor Yoke Pressing Stage: The adhesive applicator 4 is moved out of the workstation, and the rotor positioning seat 3, equipped with the rotor yoke, is moved to the workstation; the lower platform 5 carries the magnetic sheet downwards until the rotor yoke is inserted into the magnetic sheet positioning seat 601; the magnetic sheet and the rotor slots on the rotor yoke correspond one-to-one. The small cylinder 501 is activated to drive the magnetic sheet positioning plate 602 to approach the magnetic sheet, pushing the magnetic sheet to precisely press it against the rotor slots on the rotor yoke, maintaining pressure to ensure the adhesive layer cures; after pressing is completed, all actuators reset, and the transport clamp removes the assembled rotor.

[0062] Repeat the above process, and the system will then enter the next working cycle.

[0063] The flowchart demonstrates the efficient connection and coordination of multiple processes, including gluing, positioning, conveying, and pressing, revealing the automated logic by which the equipment achieves high-precision, continuous production.
