Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a dispensing device for motors. Background Technology

[0002] Today, brushless DC motors are widely used in fields such as home appliances, industrial automation, transportation, medical equipment, aerospace, consumer electronics, and high-end manufacturing. With their advantages of high reliability, energy efficiency, and precise control, they have become a core power component in modern mechatronics. One of the core components of a brushless DC motor is the rotor, which consists of a rotor shaft, magnets, and an iron core. As the rotating part of the motor, the rotor's main function is to generate torque through interaction with the stator's magnetic field, driving the motor's rotation. The installation process of the motor rotor includes pressing the iron core, applying adhesive to the magnets, and testing and adjusting the balance.

[0003] The installation of magnets requires high-strength and high-temperature resistant structural adhesive. Applying this adhesive necessitates a specialized dispensing machine. The adhesive used to bond the magnets and core is a general-purpose, high-strength retaining adhesive employing anaerobic curing technology, paired with a crucial auxiliary anaerobic adhesive activator. Therefore, the dispensing machine must have dual dispensing nozzles. However, due to the size requirements and limitations of the motor rotor's core and magnets, such equipment is not readily available on the market, or requires customization. Custom-made equipment is often too complex to be compatible with existing equipment or structures. Furthermore, externally customized equipment tends to have higher failure rates, higher prices, higher maintenance costs, and longer downtime during maintenance. Utility Model Content

The longitudinal motion mechanism cooperates with the lateral motion mechanism, and the vertical motion mechanism is connected to the lateral motion mechanism.

[0006] Furthermore, the second automatic dispensing gun assembly includes a second motor, a second gearbox, a second dispensing pump, a second dispensing valve, and a second dispensing needle. The second gearbox is connected to the second motor, the second dispensing pump is connected to the second gearbox, the second dispensing valve is connected to the second dispensing pump, and the second dispensing needle is connected to the second dispensing valve.

[0007] Furthermore, the lateral motion mechanism includes a base, a drive control unit, and a linear module. The linear module is mounted on the base, and the drive control unit is also mounted on the base. The linear module and the drive control unit are connected.

The first lead screw passes through the nut and engages with it.

[0009] Furthermore, the longitudinal motion mechanism includes a support, a first pneumatic sliding assembly, and a second pneumatic sliding assembly. The support is connected to the transverse motion mechanism. The first and second pneumatic sliding assemblies are located at opposite ends of the support, and the first and second pneumatic sliding assemblies cooperate with the support.

[0010] Furthermore, the vertical motion mechanism includes a first clamping mechanism, a second clamping mechanism, and a lifting mechanism. The first clamping mechanism, the second clamping mechanism, and the lifting mechanism are respectively connected to the lower end of the horizontal motion mechanism, and the lifting mechanism is located in the middle of the first clamping mechanism and the second clamping mechanism.

[0011] Furthermore, the first clamping mechanism includes a first clamping block, a second clamping block, a third clamping block, a fourth clamping block, and a first support column. The first and second clamping blocks are respectively connected to the transverse motion mechanism. Both the first and second clamping blocks have screw holes and are connected by screws, which simultaneously position and lock the upper end of the first support column. Both the third and fourth clamping blocks have screw holes and are connected by screws, which simultaneously position and lock the lower end of the first support column.

[0012] Furthermore, the second clamping mechanism includes a fifth clamping block, a sixth clamping block, a seventh clamping block, an eighth clamping block, and a second support column.

[0014] In this invention, a lateral motion mechanism drives the dispensing unit to move in the X-axis direction, a longitudinal motion mechanism drives the dispensing unit to move in the Y-axis direction, and a vertical motion mechanism drives the dispensing unit to move in the Z-axis direction. The dispensing unit is connected to the longitudinal motion mechanism. The lateral, longitudinal, and vertical motion mechanisms adjust the position of the dispensing unit from different spatial orientations until the dispensing unit is aligned with the motor rotor. This design offers advantages such as convenient operation, applicability to different working conditions, and cost savings in customization. Furthermore, the dispensing unit includes a first automatic dispensing gun assembly and a second automatic dispensing gun assembly. Since the first and second automatic dispensing gun assemblies are driven by the first and second pneumatic sliding assemblies in the longitudinal motion mechanism, respectively, they can simultaneously or separately drive the first and second automatic dispensing gun assemblies forward or backward. This allows the first and second automatic dispensing gun assemblies to move simultaneously or separately, completing the coordinated application of adhesive by the first and second automatic dispensing gun assemblies.

The drive motor 12 is a single unit assembled from a brushless DC motor and a driver that drives the brushless DC motor in series.

[0033] like Figure 1 and Figure 4As shown, the longitudinal motion mechanism includes a support 21, a first pneumatic sliding assembly, and a second pneumatic sliding assembly. The support 21 is installed in the positioning groove 20b of the connecting plate 20. Since the bottom of the positioning groove 20b is provided with a second through hole 20c, the support 21 is connected to the connecting plate 20 by screws. The upper two sides of the support 21 are respectively provided with an L-shaped first mounting groove 21a and a second mounting groove 21b. The first pneumatic sliding assembly and the second pneumatic sliding assembly are respectively installed in the first mounting groove 21a and the second mounting groove 21b.

The second bracket 25 positions and locks the second dispensing pump 8 by installing a positioning pin into the second pin hole 25d, thereby positioning and locking the second automatic dispensing gun assembly.

[0036] like Figure 1 and Figure 6 As shown, the vertical motion mechanism includes a first clamping mechanism, a second clamping mechanism, and a lifting mechanism. The first clamping mechanism, the second clamping mechanism, and the lifting mechanism are respectively connected to the lower end of the horizontal motion mechanism, and the lifting mechanism is located in the middle of the first clamping mechanism and the second clamping mechanism.

[0037] The first clamping mechanism includes a first clamping block 26, a second clamping block 27, a third clamping block 28, a fourth clamping block 29, and a first support column 30. The first clamping block 26 and the second clamping block 27 are respectively connected to the transverse motion mechanism. Both the first clamping block 26 and the second clamping block 27 are provided with screw holes and are connected by screws. At the same time, the upper end of the first support column 30 is positioned and locked by clamping the screw holes on the first clamping block 26 and the second clamping block 27. Both the third clamping block 28 and the fourth clamping block 29 are provided with screw holes and are connected by screws. At the same time, the lower end of the first support column 30 is positioned and locked by clamping the screw holes on the third clamping block 28 and the fourth clamping block 29. The third clamping block 28 and the fourth clamping block 29 are fixed on the equipment table.

[0038] The second clamping mechanism includes a fifth clamping block 31, a sixth clamping block 32, a seventh clamping block 33, an eighth clamping block 34, and a second support column 35. The fifth clamping block 31 and the sixth clamping block 32 are respectively connected to the transverse motion mechanism.

At the same time, the upper end of the second support column 35 is positioned and locked by clamping the screw holes on the fifth clamping block 31 and the sixth clamping block 32. Both the seventh clamping block 33 and the eighth clamping block 34 have screw holes and are connected by screws. At the same time, the lower end of the second support column 35 is positioned and locked by clamping the screw holes on the seventh clamping block 33 and the eighth clamping block 34. The seventh clamping block 33 and the eighth clamping block 34 are fixed to the equipment table.

[0039] The lifting mechanism includes a second flange 36, an oil-free bushing 37, a second lead screw 38, and a guide seat 39. The second flange 36 is fixed to the lower end of the base 11. The oil-free bushing 37 is nested between the second flange 36 and the second lead screw 38 to achieve self-lubrication and reduce maintenance requirements. The guide seat 39 is located at the bottom of the second lead screw 38 and has a blind hole with threads. The second lead screw 38 is threadedly connected to the guide seat 39. The second lead screw 38 has a clamping groove 38a in the middle. By rotating the second lead screw 38 with a wrench, the entire mechanism can be raised or lowered. The height of the vertical movement mechanism is adjusted by manually rotating the second lead screw 38 at the bottom to raise or lower the entire mechanism. In this invention, the dispensing unit is adjusted by manually rotating the second lead screw 38 at the bottom to raise or lower the entire mechanism.

[0040] The specific working process of this utility model is as follows: Before applying the adhesive, first install the motor rotor shaft with the iron core onto the clamping device (the clamping device is below the dispensing needle and parallel to the X-axis linear module, not shown in the figure). Manually operate the pneumatic slide solenoid valve to extend the first pneumatic slide 22 and the second pneumatic slide 24. Start the drive motor 12 to move the first dispensing needle 5 or the second dispensing needle 10 to the middle position of the motor rotor (the specific position depends on different working conditions). At this time, the first dispensing needle 5 or the second dispensing needle 10 is directly above the motor rotor. Measure the height to the first dispensing needle 5 or the second dispensing needle 10. Refer to the dispensing process operation guide to calculate the distance that needs to be raised and lowered for the dispensing process.

[0041] After obtaining the relevant values, loosen the clamping bolts of the first clamping mechanism and the second clamping mechanism in the vertical motion mechanism, and then use a wrench to rotate the clamping groove 38a of the second lead screw 38 in the lifting mechanism to adjust the dispensing mechanism to the required height. Then tighten the clamping bolts on the first clamping mechanism and the second clamping mechanism respectively, and the height of the entire dispensing mechanism is adjusted and locked.

[0042] The motor rotor shaft with the iron core is installed onto the clamping device (located below the dispensing needle, parallel to the X-axis linear module, not shown in the figure). The entire process can be driven and controlled by a programmable logic controller (PLC). First, the lateral motion mechanism moves the first automatic dispensing gun assembly to the same position on the X-axis of the motor rotor by controlling the rotation direction and number of revolutions of the drive motor 12 through the motor position mode. Then, the longitudinal motion mechanism activates the first pneumatic sliding assembly, which controls the extension of the first automatic dispensing gun assembly. At this time, the first dispensing needle 5 in the first automatic dispensing gun assembly is located directly above the motor rotor shaft. The first motor 1 is driven by the speed mode of the first motor 1 and the first reduction gearbox 2, thereby controlling the amount of anaerobic adhesive activator flowing out from the first dispensing needle 5 and applied to the rotor iron core. As the clamping device rotates, it drives the rotor to make a circular motion, which can evenly apply the anaerobic adhesive activator around the rotor. After the dispensing time of the first motor 1 ends, the first pneumatic sliding assembly is activated again to return the first automatic dispensing gun assembly to its original position.

[0043] Again, the lateral motion mechanism, through the motor position mode control, moves the second automatic dispensing gun assembly to the same position on the X-axis of the motor rotor by controlling the rotation direction and number of revolutions of the drive motor 12. Then, the longitudinal motion mechanism activates the second pneumatic sliding assembly, which controls the extension of the second automatic dispensing gun assembly. At this time, the second dispensing needle 10 is directly above the motor rotor shaft. Through the speed mode, the second motor 6 and the second reduction gearbox 7 are driven, thereby controlling the amount of anaerobic adhesive flowing out from the second dispensing needle 10 and applied to the rotor core. As the clamping device rotates, it drives the rotor to perform circumferential motion, which can evenly apply the anaerobic adhesive activator around the rotor. After the dispensing time of the second motor 6 ends, the first pneumatic sliding assembly is activated again to return the first automatic dispensing gun assembly to its original position.

[0044] Once the adhesive dispensing is complete, the installation of the rotor magnets can proceed.
