Description

Technical Field

[0001] This invention belongs to the field of iron core bonding technology, specifically referring to a motor iron core adhesive bonding device. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. The stator core is one of the important components of an electric motor. Common stator cores have complex structures, and most adjacent core pieces are only fixed together by clamping. This fixation is not reliable and is not conducive to the stable operation of the motor. It is necessary to use glue to fix the motor cores together.

[0003] The existing adhesive bonding equipment for motor cores has the following problems:

[0004] Existing motor core adhesive bonding equipment cannot control the tightness of the overlap between motor cores when applying adhesive, which affects the penetration of the adhesive and the final adhesive layer thickness, resulting in an adhesive layer that is too thick or too thin. Furthermore, traditional motor core adhesive bonding equipment cannot test the bonding strength between motor cores after adhesive application, and cannot guarantee the mechanical performance of the bonded cores during use.

[0005] Therefore, it cannot meet the current demand for adhesive bonding equipment for motor cores. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this solution provides a motor core adhesive bonding device that can control the tightness of the stacking between motor cores and detect the bonding strength between motor cores after adhesive bonding.

[0007] The technical solution adopted in this solution is as follows: This solution proposes a motor core adhesive bonding device, including a base, a support platform, an outer ring frame, a magnetic deformation stacking mechanism, and a coating adhesive application mechanism. Multiple sets of the support platforms are arranged on the upper wall of the base, the outer ring frame is arranged on the outside of the base, the magnetic deformation stacking mechanism is arranged on the base, and the coating adhesive application mechanism is arranged on the outer ring frame. The magnetic deformation stacking mechanism includes a guiding component, a negative suction component, a clamping component, and a magnetic drive component. The guiding component is arranged on the upper wall of the base, the negative suction component is arranged on the guiding component, the clamping component is arranged on the outer ring frame, and the magnetic drive component is arranged on the side wall of the outer ring frame. The coating adhesive application mechanism includes a coating component, a glue supply component, a glue return component, and a drive component. The coating component is arranged on the upper wall of the outer ring frame, the glue supply component is arranged on the side of the coating component away from the base, the glue return component is arranged at the bottom of the glue supply component, and the drive component is arranged at the bottom of the base.

[0008] As a further preferred embodiment of the present invention, the guiding assembly includes a guide cylinder and guide rods. The guide cylinder is located in the middle of the upper wall of the base and has an opening at its upper end. The guide rods are symmetrically arranged on the upper wall of the base. The negative suction assembly includes a sealing plate, a vacuum pump, a negative suction groove, and a negative suction port. The sealing plate is located on the upper wall of the guide cylinder and is threadedly connected to the opening of the guide cylinder. The vacuum pump is located on the upper wall of the sealing plate, and its suction end penetrates through the bottom wall of the sealing plate. Multiple sets of negative suction grooves are located on the side walls of the guide rods and have an opening at one end. Multiple sets of negative suction ports are located on the inner walls of the negative suction grooves. The clamping assembly includes a sliding plate, a positioning frame, a limiting plate, a clamping spring, an arc-shaped plate, a clamping post, and a limiting element. The frame includes multiple sets of limiting frames mounted on the upper wall of the outer ring frame, multiple sets of positioning frames mounted on the side wall of the outer ring frame, a clamping column penetrating the inner wall of the positioning frame, a limiting plate located on the side of the clamping column away from the limiting frame, a clamping spring located between the limiting plate and the positioning frame on the outer side of the clamping column, a sliding plate located on the side of the clamping column away from the limiting plate, and an arc-shaped plate slidably located on the side of the sliding plate away from the clamping column. The magnetic drive assembly includes a groove, an electromagnet, a magnetic guide port, and a soft iron block. The groove is located on the upper wall of the arc-shaped plate and is through-hole. The electromagnet is located inside the groove. Multiple sets of magnetic guide ports are located on the side of the arc-shaped plate away from the sliding plate and are connected to the groove. The soft iron block is located on the side of the arc-shaped plate near the magnetic guide port.

[0009] In use, the sealing plate is unscrewed from the opening of the guide cylinder. The silicon steel sheet to be coated is placed between the guide cylinder and the guide rod. The silicon steel sheets are gradually stacked on the upper wall of the support. At this time, the silicon steel sheets correspond one-to-one with the soft iron blocks. The sealing plate is screwed into the opening of the guide cylinder. The vacuum pump's suction end enters the inside of the guide cylinder. The electromagnet is energized and generates the same magnetism. The electromagnet magnetizes the soft iron blocks through the magnetic inlet, and the soft iron blocks magnetize the silicon steel sheets. After multiple sets of silicon steel sheets are stacked and magnetized by the same magnetic field, the silicon steel sheets will attract each other due to the magnetic field, which facilitates the coating operation between the silicon steel sheets and ensures that the coating layer thickness is uniform.

[0010] Preferably, the glue application assembly includes a glue application frame, a glue storage cylinder, a roller, a dispensing needle, a chute, a telescopic frame, and a glue application spring. Multiple sets of the glue application frames are disposed on the upper wall of the outer ring frame. The glue storage cylinder is located on the side of the glue application frame away from the outer ring frame. The chute is located on the side of the glue application frame away from the glue storage cylinder. The telescopic frame is slidably disposed inside the chute. The glue application spring is disposed between the inner wall of the chute and the telescopic frame. The roller is located at the end of the telescopic frame away from the chute. Multiple sets of dispensing needles are connected and disposed on the side wall of the roller. The glue supply assembly includes a glue supply pump and a glue supply pipe. The glue supply pump is located on the upper wall of the glue storage cylinder and supplies glue. The glue-drawing end of the pump is located inside the glue storage cylinder. The glue supply pipe passes through the glue coating frame and is connected between the roller and the glue discharge end of the glue supply pump. The glue supply pipe is rotatably connected to the roller. The glue return assembly includes a glue return pump and a glue return pipe. The glue return pump is located on the bottom wall of the glue storage cylinder. The glue discharge end of the glue return pump passes through the inside of the glue storage cylinder. The glue return pipe passes through the glue coating frame and the telescopic frame and is connected between the roller and the glue-drawing end of the glue return pump. The drive assembly includes a drive frame and a drive motor. The drive frame is located on the bottom wall of the outer ring frame. The drive motor is located on the bottom wall of the drive frame. The power end of the drive motor passes through the drive frame and is connected to the bottom wall of the base.

[0011] In use, initially, the clamping spring is shortened, and the sliding plate is located on the side away from the limit frame. Utilizing the elastic deformation characteristics of the clamping spring, the limit plate pulls the clamping column, which causes the sliding plate to fit against the inner wall of the limit frame. This increases the distance between the soft iron blocks. After all the silicon steel sheets are placed on the upper wall of the support platform, the limit plate is released. The clamping spring returns to its original deformation state and causes the sliding plate to move relative to the clamping column. The sliding plate, through the arc plate, causes the soft iron blocks to fit against the outer wall of the silicon steel sheet, thus completing the positioning operation of the silicon steel sheet.

[0012] The drive motor drives the base to rotate via the power end. The base drives the silicon steel sheet to rotate via the guide cylinder and guide rod. The telescopic frame uses the deformation characteristics of the glue-applying spring to drive the dispensing needle close to the side wall of the silicon steel sheet. The glue supply pump draws glue from the inside of the glue storage cylinder through the glue extraction end. The glue enters the inside of the roller through the glue supply pipe. The dispensing needle applies glue to the surface of the rotating silicon steel sheet. Under the action of negative pressure inside the guide cylinder, the glue is adsorbed into the inside of the silicon steel sheet, completing the glue application operation on the silicon steel sheet.

[0013] Specifically, the sliding plate has a controller on its side wall.

[0014] The controller is electrically connected to the vacuum pump, electromagnet, glue supply pump, glue return pump, and drive motor.

[0015] The beneficial effects achieved by this solution using the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a magnetically variable stacking mechanism with a coating-type adhesive application mechanism. Through the inclusion of guiding components, negative suction components, clamping components, magnetic drive components, adhesive application components, adhesive supply components, adhesive return components, and drive components, the magnetic poles of the silicon steel sheets are controlled by altering the magnetic poles of an external magnetic field. On one hand, when the silicon steel sheets are magnetized in the same magnetic field, they can be tightly attracted to each other, forming a relatively unified whole, facilitating control of the adhesive layer thickness. On the other hand, after the adhesive between the stacked silicon steel sheets has cured, different magnetic fields are used to magnetize the silicon steel sheets, generating repulsive forces between them. This allows for the testing of the adhesive's bonding performance, ensuring the bonding strength of the silicon steel sheets and contributing to improved magnetic, mechanical, and acoustic performance of the motor.

The drive motor 44 is located on the bottom wall of the drive frame 43. The power end of the drive motor 44 is inserted through the drive frame 43 and connected to the bottom wall of the base 1.

[0037] The sliding plate 13 is provided with a controller 29 on its side wall.

[0038] The controller 29 is electrically connected to the vacuum pump 9, the electromagnet 20, the glue supply pump 31, the glue return pump 34 and the drive motor 44 respectively.

[0039] In actual use, in the initial state, the clamping spring 16 is shortened, the sliding plate 13 is located on the side away from the limit frame 45, and the glue-applying spring 41 is extended. The operator unscrews the sealing plate 8 from the opening of the guide cylinder 5 and uses the deformation characteristics of the clamping spring 16 and the glue-applying spring 41 to pull the telescopic frame 40 and the limit plate 15 respectively. The limit plate 15 pulls the clamping column 38, and the clamping column 38 causes the sliding plate 13 to fit against the inner wall of the limit frame 45, increasing the distance between the soft iron blocks 22. The telescopic frame 40 drives the glue-applying needle 28 to move in opposite directions through the roller 27.

[0040] The silicon steel sheet to be coated is placed between the guide cylinder 5 and the guide rod 6. The silicon steel sheet slides down along the guide cylinder 5 and the guide rod 6 and gradually stacks on the upper wall of the support platform 2. The silicon steel sheets stacked on the upper wall of the support platform 2 correspond one-to-one with the soft iron block 22. After all the silicon steel sheets are placed on the upper wall of the support platform 2, the limiting plate 15 and the telescopic frame 40 are released. The clamping spring 16 deforms and resets, and drives the sliding plate 13 to move relative to the clamping column 38. The sliding plate 13 drives the soft iron block 22 to fit against the outer wall of the silicon steel sheet through the arc plate 17, thus completing the positioning operation of the silicon steel sheet. The telescopic frame 40 uses the deformation characteristics of the coating spring 41 to drive the dispensing needle 28 to approach the side wall of the silicon steel sheet. Then, the sealing plate 8 is screwed into the opening of the guide cylinder 5. The vacuum pump 9 enters the interior of the guide cylinder 5 along with the sealing plate 8.

[0041] The controller 29 controls the electromagnet 20 to start. When the electromagnet 20 is energized, it generates the same magnetism. The electromagnet 20 magnetizes the soft iron block 22 through the magnetic guide port 21. The soft iron block 22 magnetizes the silicon steel sheet. After multiple sets of silicon steel sheets are stacked and magnetized by the same magnetic field, the silicon steel sheets will attract each other due to the magnetic field. This facilitates the application of adhesive between the silicon steel sheets and ensures that the adhesive layer thickness is uniform.

[0042] The controller 29 controls the glue supply pump 31 to start. The glue supply pump 31 draws glue from the inside of the glue storage cylinder 26 through the glue extraction end. The glue enters the inside of the roller 27 through the glue supply pipe 32. The glue dispensing needle 28 applies the glue inside the roller 27 to the surface of the silicon steel sheet. The controller 29 controls the drive motor 44 to start. The drive motor 44 drives the base 1 to rotate through the power end. The base 1 drives the silicon steel sheet to rotate through the guide cylinder 5 and the guide rod 6. The glue dispensing needle 28 evenly applies glue to the surface of the rotating silicon steel sheet.

[0043] The controller 29 controls the vacuum pump 9 to start. The vacuum pump 9 discharges the air inside the guide cylinder 5 through the air extraction end. After the pressure inside the guide cylinder 5 decreases, the glue is drawn into the space between the silicon steel sheets through the tiny gaps between the silicon steel sheets. Under the action of negative pressure, the glue is adsorbed into the inside of the silicon steel sheets. The negative suction ports 11 are evenly distributed in a matrix on the inner wall of the negative suction groove 10. After the vacuum pump 9 starts, the radial adsorption force generated by the negative suction ports 11 can form a circumferential uniform constraint on the stacked silicon steel sheets, prompting the silicon steel sheets to automatically calibrate the flatness, reducing the magnetic field blind zone caused by surface unevenness, and further ensuring the uniformity of the adsorption force between the silicon steel sheets, thereby completing the glue application operation on the silicon steel sheets.

[0044] After the upper and lower walls of the silicon steel sheet are coated with adhesive, they are left to stand for the adhesive to cure. Then, the controller 29 controls the current to flow into the adjacent electromagnets 20 in opposite directions, so that the magnetic fields generated by the adjacent electromagnets 20 are opposite. The electromagnets 20 are evenly arranged in a ring array in the groove 19 of the arc plate 17. The excitation parameters of each group of electromagnets 20 are the same. The uniform magnetic field is transmitted to the soft iron block 22 through the magnetic guide port 21. Combined with the elastic fit of the clamping component 12 and the negative pressure calibration of the negative suction component 7, even if the silicon steel sheet has superposition tolerance or uneven surface roughness, the uniform magnetization of the silicon steel sheet can still be achieved, ensuring the attraction force between adjacent silicon steel sheets, thereby ensuring that the coating thickness fluctuation is controlled within the specified range, and achieving the technical effect of ensuring uniform coating thickness.

[0045] The electromagnet 20 has 500-800 coil turns, a wire diameter of 0.3-0.5mm, a rated operating voltage of 24V, an input current adjustment range of 0.5-3A, and a corresponding magnetic field strength of 0.1-0.8T. The soft iron block 22 is made of DT4 pure iron with a permeability μ≥4.5×10⁻³H / m to ensure efficient magnetic field conduction. The electromagnet 20 magnetizes the soft iron block 22 through the magnetic inlet 21, and the silicon steel sheets superimposed on the soft iron block 22 are also magnetized. When the two silicon steel sheets are magnetized under different magnetic fields, they become two independent magnets.

[0046] When silicon steel sheets are magnetized in the same magnetic field, the bottom wall of the upper silicon steel sheet and the top wall of the lower silicon steel sheet are in an opposite pole attraction state: N pole-S pole, N pole-S pole, N pole-S pole, N pole-S pole arrangement. When the magnetic pole of the lower silicon steel sheet changes, the magnetic pole of the upper silicon steel sheet remains unchanged: N pole-S pole, S pole-N pole, N pole-S pole, S pole-N pole arrangement, so that the magnetic pole of the bottom wall of the upper silicon steel sheet and the magnetic pole of the top wall of the lower silicon steel sheet are set with the same pole. At this time, the silicon steel sheets generate a mutual repulsive force.

[0047] The controller 29 has a built-in current adjustment module and displacement monitoring interface. It can precisely control the magnitude of the repulsive force by adjusting the input current of the electromagnet 20. It can also be connected to an external laser displacement sensor (a standard accessory) to monitor the relative displacement between the silicon steel sheets in real time, enabling quantitative detection of the adhesion strength. After the adhesive between the silicon steel sheets has cured, the controller 29 adjusts the direction (opposite) and magnitude of the input current of adjacent electromagnets 20 according to preset levels, setting three levels of detection standards:

[0048] First-level test: Input current 1A (corresponding to a repulsive force of approximately 500N). If the relative displacement of the silicon steel sheet is ≤0.01mm, the adhesion strength is deemed to meet the minimum usage requirements of the motor core.

[0049] Second-stage test: Input current 2A (corresponding to a repulsive force of approximately 1000N). If the relative displacement of the silicon steel sheet is ≤0.01mm, the adhesion strength is deemed to meet the rated usage requirements.

[0050] Three-stage testing: Input current 3A (corresponding to a repulsive force of approximately 1500N). If the relative displacement of the silicon steel sheet is ≤0.01mm, the adhesion strength is deemed to meet the ultimate service requirements.

[0051] If the displacement exceeds 0.01mm in a certain gear position, the controller 29 will issue an alarm signal, indicating that the bonding strength of the motor core is substandard. The relationship between the repulsive force and the current is calculated based on the electromagnetic formula F=k×B²×S (where k is a constant, B is the magnetic field strength, and S is the contact area of ​​the silicon steel sheet). Those skilled in the art can adjust the current parameters according to the actual size of the silicon steel sheet to test the bonding strength of the adhesive and ensure the performance of the bonded silicon steel sheet as a motor core. The above procedure can be repeated for the next use.

[0052] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0053] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
