Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment, and in particular to a rotor core adhesive coating machine. Background Technology

[0002] The rotor core is the core component of the motor rotor, its main function being to form the magnetic circuit and generate electromagnetic torque. It is typically made of laminated silicon steel sheets with excellent magnetic permeability, rather than solid metal, which effectively reduces eddy current losses and hysteresis losses during motor operation, significantly improving efficiency. From a manufacturing perspective, the quality of the rotor core has a significant impact on motor performance. Excessive burrs during lamination will exacerbate eddy current losses, leading to decreased motor efficiency; loose or uneven lamination may cause magnetic circuit obstruction, increasing excitation current and raising motor temperature. For cast aluminum rotors, casting defects such as broken or thin bars in the core slots will directly weaken the starting torque, and in severe cases, may even prevent the motor from starting normally.

[0003] The rotor core is bonded to silicon steel sheets with adhesive to form a robust whole, capable of withstanding the enormous centrifugal force at ultra-high speeds and preventing the core from disintegrating. Furthermore, the adhesive fills and insulates the gaps between the silicon steel sheets, blocking eddy current losses and significantly improving motor efficiency and performance. Current adhesive coating equipment typically has only a single station, and loading / unloading and adhesive coating operations cannot be synchronized, leading to extended processing cycles and limited production efficiency. Additionally, existing equipment lacks sufficient height adjustment capability for the workpiece placement structure, making it difficult to accommodate rotor cores of different heights, thus reducing the equipment's versatility and applicability.

[0031] Figures 1 to 8 The diagram shown is a structural schematic of an embodiment of the rotor core coating machine of this utility model.

[0032] The rotor core coating machine includes a support base 1, and a support frame shell 2 is connected to the top of the support base 1; The placement unit is connected to the top of the support base 1, and the adhesive application unit is installed in the inner cavity of the support frame 2. The placement unit is used to place the rotor core, and the adhesive application unit is used to apply adhesive to the rotor core. The placement unit includes a fixed frame 3, which is connected to the top of the support base 1. Multiple placement cylinders 4 are embedded in the fixed frame 3.

A glue tank 9 is located below the extrusion assembly 8. The glue tank 9 is detachably connected to the mounting plate 7 via a disassembly assembly 10.

[0033] The position of the adhesive tank 9 and other structures can be adjusted by the moving mechanism to facilitate the application of adhesive to the rotor core at different positions. The adhesive tank 9 can be easily installed and disassembled by the disassembly and assembly component 10, and the adhesive in the adhesive tank 9 can be extruded onto the rotor core by the extrusion component 8 to complete the adhesive application process of the rotor core. At the same time, the extrusion component 8 can control the amount of adhesive extruded each time to improve the adhesive application accuracy. Multiple rotor cores can be placed in multiple placement cylinders 4, giving the rotor cores multiple gluing stations. This allows gluing and loading / unloading to be carried out simultaneously, saving time on rotor core loading / unloading and improving gluing efficiency. At the same time, the lifting and control component 6 can adjust the height of the moving base plate 5, allowing the placement cylinders 4 to hold rotor cores of different heights, expanding the applicability of the rotor cores and increasing the practicality of the gluing machine.

[0034] The lifting control component 6 includes a sliding support column 61, the top of which is connected to the bottom of the movable base plate 5, the surface of which is slidably connected to the bottom surface of the placement cylinder 4, and a lifting plate 62 connected to the bottom of which is the sliding support column 61. An elastic connector 63 is connected between the inner wall of the bottom surface of the placement cylinder 4 and the movable base plate 5. The elastic connector 63 is sleeved on the surface of the sliding support column 61.

[0035] The height of the movable film 5 can be adjusted using the lifting and adjusting component 6.

[0038] The height of the moving film 5 is adjusted by rotating disk 65 and eccentric wheel 64.

[0039] In use, the corresponding rotating disk 65 is rotated according to the height of the rotor core, thereby driving the eccentric wheel 64 to rotate. When the eccentric wheel 64 rotates, it drives the lifting plate 62 to move up or down, which in turn drives the sliding support 61 to move in the same direction, thereby driving the moving base plate 5 to move in the same direction, so that rotor cores of different heights can be placed in the inner cavity of the placement cylinder 4 for adhesive treatment.

[0045] The rotation of the threaded shaft 81 is provided by structures such as the extrusion power source 85.

[0046] Specifically, the transmission belt 87 wraps around the surfaces of the two transmission pulleys 86.

[0047] In use, the extrusion power source 85 drives the corresponding transmission wheel 86 to rotate, which in turn drives the transmission belt 87 to rotate, which in turn drives another transmission wheel 86 to rotate, which in turn drives the threaded shaft 81 to rotate. When the threaded shaft 81 rotates, it drives the moving plate 82 to move along the fixed track 84, thereby driving the extrusion column 83 to move in the same direction. The extrusion column 83 is used to extrude the glue tank 9, squeezing out the glue in the glue tank 9 and completing the glue coating process.

[0048] The adhesive container 9 includes a container body 91, a squeezing piston 92 slidably disposed in the inner cavity of the container body 91, and an adhesive applicator 93 threadedly connected to the bottom end of the container body 91. This allows the adhesive applicator 93 to be replaced.

[0050] When in use, the extrusion column 83 moves downward, driving the extrusion piston 92 to move in the same direction. When the extrusion piston 92 moves, it can squeeze the adhesive in the can 91 out of the application head 93 to complete the application operation.

[0051] A sensor is installed at the placement rack 101 to detect the presence of the glue tank 9. The glue applicator is only allowed to perform the glue applicator operation when the sensor detects the presence of the glue tank 9.

[0054] When in use, place the glue container 9 inside the storage rack 101, and then turn the locking knob 102 to move the locking knob 102 and press it against the glue container 9 to fix the position of the glue container 9.

[0055] The moving mechanism includes a support plate frame 11, the side of which is connected to the actuating end of the horizontal adjustment component 12, and a vertical adjustment component 13 is connected to one side of the support plate frame 11, the actuating end of the vertical adjustment component 13 being connected to the mounting plate frame 7.

[0056] The horizontal and vertical positions of the adhesive container 9 are adjusted by a moving mechanism.

[0057] The horizontal adjustment assembly 12 includes telescopic devices 121. Multiple telescopic devices 121 are connected to the outside of the support frame 2. The output end of the telescopic device 121 is connected to one side of the support plate frame 11. Sliding blocks 122 are connected to both sides of the support plate frame 11. The sliding blocks 122 are slidably connected to the surface of the guide shaft 123. The two ends of the guide shaft 123 are respectively connected to the inner wall of the support frame shell 2.

[0058] The lateral position of structures such as the mounting plate frame 7 and the adhesive tank 9 is adjusted by the lateral adjustment component 12.

[0059] In use, the telescopic device 121 drives the support plate frame 11 to move, thereby driving the sliding block 122 to move in the same direction along the guide shaft 123; When the support frame 11 moves, it drives the mounting frame 7 and the glue tank 9 to move in the same direction, thereby adjusting the position of the glue tank 9.

[0060] The longitudinal adjustment assembly 13 includes a longitudinal adjustment motor 131, which is mounted on one side of the mounting plate frame 7. The output end of the longitudinal adjustment motor 131 is connected to a rotating gear 132. The side of the rotating gear 132 meshes with one side of the fixed rack 133, and one side of the fixed rack 133 is connected to one side of the support plate frame 11. Multiple guide sliders 134 are connected to the side of the mounting plate 7 near the support plate 11. The guide sliders 134 are slidably connected to the surface of the positioning rail 135, which is connected to one side of the support plate 11.

[0061] The longitudinal position of structures such as the mounting plate frame 7 and the adhesive tank 9 is adjusted by the longitudinal adjustment component 13.

[0062] In use, the longitudinal adjustment motor 131 drives the rotating gear 132 to rotate. At this time, under the action of the fixed rack 133, the mounting plate frame 7 is moved, thereby driving the guide slider 134 to move in the same direction along the positioning track 135. When the mounting plate frame 7 moves, it drives the disassembly and assembly components 10 and the glue tank 9 to move in the same direction, adjusting the longitudinal position of the glue tank 9 so that the glue tank 9 can apply glue to the rotor core at different positions.

[0063] The extrusion power source 85 and the longitudinal adjustment motor 131 are motors or other devices that can output rotational kinetic energy.
