Description

A brushless DC motor and its processing system Technical Field

[0001] This invention relates to the field of assembly equipment, specifically to a brushless DC motor and its processing system. Background Technology

[0002] Brushless DC motors use permanent magnets as rotors. If the rotor position is uncertain, it will directly lead to motor starting failure or temporary reverse rotation. Therefore, detecting the motor rotor position is crucial for starting a brushless DC motor. Among the methods for detecting rotor position, the simplest and most mature is the back EMF detection method: this method detects the zero-crossing point of the back EMF signal extracted from the motor terminal voltage, then delays it by 30° to obtain commutation information. However, when the motor is starting or at very low speeds, the back EMF is zero or very small, making it impossible to accurately detect the rotor position signal.

[0003] Therefore, existing technologies, such as the DC brushless motor rotor position detection device and method described in patent CN115912801B, employ a contact method between a conductive component and a resistor ring. When the rotor rotates, the conductive component rotates synchronously. By measuring the length of the resistor ring connected to the circuit, the angle through which the conductive component rotates from the beginning of the resistor ring can be calculated, thereby obtaining the position information of the motor rotor.

[0004] However, during the assembly of this brushless DC motor, to ensure that the conductive coils in the conductive components are in close contact with the resistance rings and conductive rings respectively, the conductive coils need to be snapped into the resistance rings and conductive rings. This assembly method, when performed manually, greatly increases the labor intensity of workers and reduces production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above problems by providing a DC brushless motor processing system that can reduce the labor intensity of workers.

[0006] To achieve the above objectives, the technical solution adopted in this application is: a DC brushless motor processing system, including a worktable, an assembly area provided at the upper end of the worktable, an assembly mechanism and a clamping mechanism provided in the assembly area, the clamping mechanism and the assembly mechanism being spaced apart along the workpiece axial direction, the assembly mechanism including a bracket, the bracket moving along the workpiece axial direction, the bracket being provided with a rotating part, a drive rod and an assembly drive mechanism, the rotating part being arranged along the workpiece axial direction, the rotating part rotating around its axis under the drive of a workpiece rotary motor, the rotating part being provided with a connecting mechanism for connecting the workpiece; the drive rod moving radially along the workpiece, the drive rod extending towards the clamping mechanism side; the assembly drive mechanism driving the pushing part to move along the workpiece axial direction.

[0007] The aforementioned brushless DC motor processing system can be used for the assembly of the brushless DC motor described in the authorization announcement number CN115912801B. The brushless DC motor includes a housing, a rotor shaft movably disposed in the middle of the housing, a measuring body disposed on the rear end cover of the housing, and a module structure disposed on the end of the measuring body away from the housing.

[0008] The measuring body includes a shaft column movably disposed at the rear end of the housing, a conductive component movably disposed around the shaft column, and a resistance ring and a conductive ring fixedly disposed at the rear end of the housing. One end of the shaft column near the housing is fixedly connected to the end of the rotor shaft, and the shaft column and the rotor shaft are collinear. The conductive component rotates synchronously with the shaft column. One end of the conductive component is pressed against the inner surface of the resistance ring, and the other end is pressed against the inner surface of the conductive ring, electrically connecting the resistance ring and the conductive ring. The first and second ends of the resistance ring are insulated and abut against each other, forming a complete circular structure. The resistance ring and the conductive ring do not contact each other. Terminals are provided at the first end of the resistance ring and around the periphery of the conductive ring, and connected to the detection circuit. The resistivity of the resistance ring is equal everywhere, and the resistance of the resistance ring between its first end and the contact point with the conductive component changes with the position of the conductive component.

[0009] The module structure includes a signal detection and conversion module disposed at the end of the measuring body away from the housing. The signal detection and conversion module is used to detect the voltage and circuit current of the resistor ring connected to the detection circuit, and to convert the detection signal into a position signal after the conductive component rotates with the shaft column. The rear end cover of the housing is fixedly provided with a positioning shell, and the resistor ring, conductive ring and insulating ring are all fixedly disposed on the inner side wall of the positioning shell.

[0010] The measuring body also includes a positioning block fixedly disposed on the periphery of the shaft column, and an extension block elastically disposed at the end of the positioning block away from the shaft column. The conductive component is disposed at the end of the extension block away from the positioning block.

[0011] The conductive component includes an insulating post movably disposed on the inner side of the end of the elongated block away from the positioning block, and a conductive post fixedly disposed in the middle of the periphery of the insulating post. Each end of the conductive post has an integrally formed conductive ring, one of which abuts against a resistance ring, and the other abuts against a conductive ring. The outer surface of the conductive ring has an arc-shaped cross-section, and the inner surfaces of the resistance ring and the conductive ring have arc-shaped cross-sections of the same curvature, which are adapted to match the outer surface of the conductive ring. An elastic ring is fixedly disposed in the middle of the periphery of the conductive post, and an insulating ring is fixedly disposed between the resistance ring and the conductive ring. The outer surface of the elastic ring and the inner surface of the insulating ring are pressed together.

[0012] The positioning block has a limiting groove adapted to the elongated block at one end away from the shaft column. One end of the elongated block is movably disposed inside the limiting groove and slides inside the limiting groove. An inner groove is formed in the middle of the end of the elongated block near the limiting groove. A positioning tube is fixedly disposed on the inner wall of the limiting groove. A connecting tube is fixedly disposed on the inner wall of the inner groove. One end of the connecting tube is movably disposed inside one end of the positioning tube. A spring is sleeved around the periphery of the positioning tube and the connecting tube. One end of the spring abuts against the inner wall of the limiting groove, and the other end of the spring abuts against the inner wall of the inner groove. A counterweight is fixedly disposed on the side of the shaft column away from the positioning block.

[0013] Furthermore, the connecting mechanism includes an insertion part, one end of which is keyed to the rotating part and moves axially along the rotating part. The other end of the insertion part is connected to a support, and the support has a connecting part for connecting with the workpiece at one end of the clamping mechanism. This design ensures that when the support moves towards the workpiece, the connecting part connects to the workpiece before the drive rod. Then, the connecting part drives the shaft column in the workpiece to rotate, so that the position of the conductive component on the shaft column is opposite to the drive rod. This ensures that the drive rod can push the conductive component to move inward towards the shaft column, so that the conductive component does not interfere with the installation of the positioning shell.

[0014] Furthermore, to ensure that the workpiece cannot move during assembly, the clamping mechanism includes a support base, and clamping parts are provided on both sides of the support base, with the clamping parts on both sides moving relative to each other.

[0015] Furthermore, the clamping mechanism also includes a reference part to ensure that the distance between the workpiece and the assembly mechanism remains consistent, thereby ensuring the normal progress of the assembly process.

[0016] Furthermore, to improve the level of automation, it also includes an identification mechanism. This mechanism includes a mounting base that moves radially along the workpiece, and a detection sensing unit is mounted on the mounting base. The detection sensing unit is used to detect the position of conductive rings and other components within the workpiece. When the positioning shell needs to be mounted on the machine housing, the drive rod can push the conductive rings inwards towards the machine housing, thereby ensuring the normal progress of the assembly process and reducing the need for manual alignment.

[0017] Furthermore, since there is a certain time delay in the operation of the identification mechanism and the stopping of the rotation of the shaft column by the connecting mechanism, the conductive component may deviate from the extended axis of the drive rod. To ensure that the drive rod and the conductive component are aligned, it also includes an inspection mechanism opposite to the identification mechanism. The inspection mechanism includes a positioning part that moves radially along the workpiece and pushes the shaft column in the workpiece to rotate, so that the end face of the insulating column in the conductive component is aligned with the drive rod.

[0018] Furthermore, the positioning part includes two positioning rods symmetrically arranged around the workpiece axis. The upper ends of the two positioning rods extend obliquely upward in opposite directions, so that the two positioning rods are V-shaped open. During the movement of the positioning part toward the shaft column, the positioning rods abut against the counterweight and drive the shaft column to rotate.

[0019] Furthermore, to improve the level of automation, the worktable is provided with a feeding part that moves radially along the workpiece. The feeding part is provided with a placement hole, the axis of which is in the same direction as the workpiece axis, and both ends of the placement hole are open.

[0020] Furthermore, a telescopic positioning mechanism is provided on the inner wall of the storage hole to ensure that the positioning shell remains in a uniform position within the storage hole and will not fall out of the storage hole.

[0021] Furthermore, to improve the level of automation, a loading area is set on the upper part of the workbench on one side of the assembly area. A positioning shell storage part is set in the loading area. One end of the positioning shell storage part is open. A loading plate is set on the far side of the open end inside the positioning shell storage part. The loading plate moves along the workpiece axis under the push of the loading drive mechanism. The feeding part moves between the loading area and the assembly area. When the feeding part moves to the loading area, the feeding part is located on the open end side of the positioning shell storage part.

[0022] The beneficial effects of this application are as follows: When installing components such as the positioning shell onto the housing of workpieces such as brushless DC motors, the rotating part is first connected to components such as the shaft column in the workpiece via a connecting mechanism. Then, the rotating part drives the shaft column to rotate, aligning the conductive component on the shaft column with the drive rod. Next, the drive rod connects to the conductive component and moves the conductive component towards the shaft column. In this way, the conductive component does not interfere with the installation of the positioning shell during installation, thus ensuring that the conductive ring can smoothly engage with the resistance ring and the conductive ring. This method effectively reduces the labor intensity of workers and improves production efficiency. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0029] Example 1, as shown in Figures 1-4, is a DC brushless motor processing system. It is used in the DC brushless motor described in patent publication number CN115912801B to mount the positioning shell onto the motor housing. In this example, workpiece 4 is the motor housing. At this time, the shaft column 26 in the measuring body has been mounted on the rotor shaft, and the positioning block 27, conductive component 30, etc., have also been installed. The conductive component 30 is mounted on the positioning block using the elastic mode described in the patent, that is, the end of the positioning block 27 away from the shaft column 26 has an opening... A limiting groove adapted to the elongated block is provided. One end of the elongated block is movably disposed inside the limiting groove and slides within it. An inner groove is formed in the middle of the end of the elongated block adjacent to the limiting groove. A positioning tube is fixedly disposed on the inner wall of the limiting groove, and a connecting tube is fixedly disposed on the inner wall of the inner groove. One end of the connecting tube is movably disposed inside one end of the positioning tube. A spring is sleeved around the periphery of the positioning tube and the connecting tube. One end of the spring abuts against the inner wall of the limiting groove, and the other end of the spring abuts against the inner wall of the inner groove. This connection method allows the conductive component 30 to move radially along the shaft 26. Simultaneously, the positioning shell 28 and the housing 29 are temporarily fixed by nesting, and then tightened by bolts, welding, or other methods. Meanwhile, the resistance ring, conductive ring, and insulating ring are already installed on the inner wall of the positioning shell 28.

[0030] A DC brushless motor processing system includes a worktable 1, with an assembly area at its upper end. The assembly area contains an assembly mechanism 2 and a clamping mechanism 3, which are spaced apart along the workpiece 4. The assembly mechanism 2 includes a support 5, which moves along the workpiece 4 under the action of a linear module, an electric push rod, etc. Alternatively, the upper end of the worktable 1 has a sliding groove, and the lower end of the support 5 has a sliding seat connected to a lead screw in the sliding groove. The lead screw rotates under the drive of a motor, thereby moving the support 5. The support 5 is equipped with a rotating part 6, a drive rod 7, and an assembly drive mechanism 8. The rotating part 6 is arranged along the workpiece axial direction. One end of the rotating part 6 is connected to a bearing on the bracket 5, and the other end of the rotating part 6 is connected to a connecting mechanism. The connecting mechanism includes an insertion part 11 arranged in the same direction as the rotating part 6. One end of the insertion part 11 extends into a receiving groove provided on the end face of the rotating part 6. The cross-section of the receiving groove can be rectangular. A key in the same direction is provided on the side wall of the insertion part 11. The key is adapted to the sliding groove on the side wall of the receiving groove. The end face of the insertion part at one end of the rotating part 6 is connected to the receiving groove by a telescopic spring. The telescopic spring is arranged in the same direction as the rotating part 6. The other end of the insertion part 11 is connected to a support. The support is provided with a connecting part 12 for connecting to the workpiece 4 at one end of the clamping mechanism. The connecting part 12 can be a pneumatic gripper, a magnet, etc. When the end face of the shaft column 26 is a smooth plane, the connecting part 12 can be a vacuum suction cup, etc. The rotating part 6 rotates around its axis under the drive of the workpiece rotating motor 9, which is mounted on the bracket 5.

[0031] The drive rod 7 moves radially along the workpiece 4. For this purpose, the bracket 5 is provided with longitudinal grooves, guide rails, etc. The drive rod 7 is adapted to the longitudinal grooves and guide rails, etc. The bracket 5 is provided with a radial drive mechanism, which adopts linear modules, electric push rods, etc. The output end of the radial drive mechanism is connected to the drive rod 7. The drive rod 7 extends towards the clamping mechanism 3. The distance between the end face of the drive rod 7 and the clamping mechanism 3 on the clamping mechanism 3 side is greater than the distance between the connecting part 12 and the clamping mechanism 3 under normal conditions, so that the connecting part 12 contacts the workpiece 4 before the drive rod 7.

[0032] The assembly drive mechanism 8 drives the push part 10 to move along the workpiece axis. The assembly drive mechanism 8 can be a hydraulic cylinder, an electric push rod, etc. In order to increase the contact area between the push part 10 and the positioning shell 28, the push part 10 can be a ring structure.

[0033] The clamping mechanism 3 includes a support base 13. The support base 13 is configured such that when the workpiece 4 is placed on the support base 13, the axis of the shaft 26 and the insulating column thereon are horizontal. Clamping parts 14 are provided on both sides of the support base 13. The clamping parts 14 on both sides are symmetrically arranged about the axis of the shaft 26. At the same time, the clamping parts 14 can move radially along the shaft 26 under the push of existing linear drive mechanisms such as cylinders or electric push rods. The clamping mechanism 3 also includes a reference part 15. The upper end surface of the reference part 15 is higher than the upper end surface of the support base 13, so that the end face of the workpiece 4 can abut against the reference part 15.

[0034] The specific working process is as follows: The worker places the workpiece 4 on the upper end of the support base 13 with the shaft column 26 facing the assembly mechanism 2. Then, the clamping parts 14 on both sides of the workpiece 4 move toward the workpiece 4 to fix the workpiece on the support base 13.

[0035] Then, the worker places the positioning shell 28, required for assembly, between the assembly mechanism 2 and the clamping mechanism 3 by hand, with the positioning shell 28 coaxially placed with the shaft 26. After the positioning shell 28 is placed, the bracket 5 moves towards the workpiece 4. During the movement, the connecting part 12 establishes a temporary connection with the end face of the shaft 26 on the workpiece 4 before the drive rod 7. After the connection is established, the rotating part 6 drives the shaft 26 to rotate, so that the conductive component 30 on the workpiece 4 is aligned with the drive rod 7. At this time, the conductive component 30 is located directly above the shaft 26. Then, the bracket 5 continues to move so that the drive rod 7 can drive the conductive component 30 to move towards the shaft 26. The drive rod 7 and the conductive component 30 can be connected in two ways: one is that since the outer wall of the conductive ring is higher than the extension block, the drive rod 7 is located above the extension block of the conductive component 30, and the conductive component 30 can be moved by pressing the extension block; the other is that the insulating post in the conductive component 30 is set as a ring structure, so that the drive rod 7 can be inserted into the insulating post, thereby driving the conductive component 30 to move towards the shaft 26.

[0036] After the conductive component 30 moves, the pushing part 10 moves towards the workpiece 4 under the push of the assembly drive mechanism 8, thereby pushing the positioning shell 28 onto the workpiece 4. To ensure that the positioning shell 28 will not fall off the workpiece 4, an end cover plate is provided on the end face of the workpiece 4. The end cover plate is provided with a stop edge concentric with the shaft column 26. The side wall of the positioning shell 28 is tightly fitted with the side wall of the stop edge. In this way, during assembly, the positioning shell 28 and the stop edge are nested together, ensuring that the positioning shell 28 is not easy to fall off the workpiece 4. After the positioning shell 28 is installed, the bracket 5 drives the rotating part 6, the drive rod 7 and the assembly drive mechanism 8 away from the workpiece. At this time, under the action of the spring, the conductive ring in the conductive component 30 moves outward from the shaft column 26, so that the outer wall of the conductive ring is engaged in the resistor ring and the conductive ring. One conductive ring abuts against the inner wall of the resistor ring, and the other conductive ring abuts against the inner wall of the conductive ring. Then the clamping part 14 moves away from the workpiece, the operator removes the workpiece 4, and then fixes the positioning shell 28 to the workpiece 4 by bolts, welding or other means.

[0037] Example 2, as shown in Figures 2-3, shares the same structure and operating process as Example 1. However, this example further includes an identification mechanism and an inspection mechanism arranged opposite to each other, both located between the assembly mechanism 2 and the clamping mechanism 3. The identification mechanism includes a mounting base 16, which moves radially along the workpiece 4 under the action of a linear module, etc. A detection sensing unit 17 is mounted on the mounting base 16. The inspection mechanism includes a positioning part 18, which moves radially along the workpiece 4 under the action of a linear module, an electric push rod, etc. In this example, the detection sensing unit 17 is located directly above the shaft column 26, and the positioning part 18 is located directly below the shaft column 26.

[0038] The positioning part 18 includes two positioning rods 19 symmetrically arranged with the workpiece axis as the axis, and the upper ends of the two positioning rods 19 extend upward in a V shape.

[0039] Specific working process: When the connecting part 12 drives the shaft 26 to rotate, the distance from the outer wall of the conductive ring in the conductive component 30 to the center point of the shaft 26 is greater than the distance from the outer wall of the counterweight to the center point of the shaft 26. Thus, the detection sensing unit 17 can be a proximity switch, touch switch, pressure sensor, etc. The distance from the sensing end of the detection sensing unit 17 to the center point of the shaft 26 is matched with the distance from the conductive ring to the center point of the shaft 26. When the conductive ring rotates to the detection sensing unit 17, the detection sensing unit 17 sends a check signal to the control system. After receiving the signal, the control system analyzes the detection signal and then outputs a control signal to stop the workpiece rotation motor 9 that drives the rotating part 6. Due to the influence of feedback mechanisms, the conductive component 30 may not be aligned with the drive rod 7 at this time. Therefore, after the workpiece rotation motor 9 stops working, the positioning part 18 rises, the positioning rod 19 contacts the counterweight, thereby rotating the shaft 26 so that the counterweight rotates to be directly below the shaft 26, that is, the conductive component 30 is aligned with the drive rod 7. After the position of the conductive component 30 is corrected, the drive rod 7 is connected to the conductive component 30 again. After the connection is established, the positioning part 18 and the detection sensing unit 17 are moved away from the workpiece 4 to facilitate the installation of the positioning shell 28.

[0040] Example 3, as shown in Figures 1-2, has the same structure and working process as Example 1. However, in this example, the worktable 1 is provided with a feeding part 20 that moves radially along the workpiece. The driving method of the feeding part 20 is the same as the driving mechanism of the bracket 5. The feeding part 20 is provided with a placement hole 21. The axis of the placement hole 21 is in the same direction as the axis of the workpiece 4. The two ends of the placement hole 21 are open, and the inner diameter of the placement hole 21 is adapted to the outer diameter of the positioning shell 28. A telescopic positioning mechanism 22 is provided on the inner wall of the placement hole 21. The telescopic positioning mechanism 22 can be a spring positioning pin. That is, the inner wall of the placement hole 21 is provided with grooves in a ring array. The positioning pin is inserted into the groove, and the end of the positioning pin extending out of the groove is set as a ball head. The end of the positioning pin located in the groove is connected to the inner end face of the groove through a positioning spring. Alternatively, the telescopic positioning mechanism 22 can be made of materials such as rubber or silicone to lock the positioning shell 28. A loading area is provided on the upper end of the workbench 1 on one side of the assembly area. A positioning shell storage part 23 is provided in the loading area. One end of the positioning shell storage part 23 is open. A loading plate 24 is provided on the far side of the open end inside the positioning shell storage part 23. The loading plate 24 moves along the workpiece axis under the push of the loading drive mechanism 25. The loading drive mechanism 25 can be an electric push rod, a linear module, etc. The feeding part 20 moves between the loading area and the assembly area. When the feeding part 20 moves to the loading area, the feeding part 20 is located on the open end side of the positioning shell storage part 23. At the same time, the upper end of the positioning shell storage part 23 is also set to be open to facilitate the placement of the positioning shell 28 inside.

[0041] Specific working process: The feeding part 20 first moves to the open side of the positioning shell storage part 23. At this time, the distance between the end face of the feeding part 20 and the end face of the positioning shell storage part 23 must ensure that the positioning shell 28 can move from the positioning shell storage part 23 into the storage hole 21.

[0042] Then, the loading plate 24 moves towards the feeding section 20, pushing the outermost positioning shell in the positioning shell storage section 23 into the placement hole 21 of the feeding section 20. Next, the feeding section 20 carries the positioning shell 28 to the assembly area, making the positioning shell 28 coaxial with the shaft column 26. After the positioning shell 28 has moved, the installation of the positioning shell 28 begins according to the working process of Embodiment 1.
