Abstract
Description
Technical Field
[0001] The present invention relates to the field of assembly equipment, and specifically to a DC brushless motor processing system. Background Art
[0002] A DC brushless motor uses a permanent magnet as the rotor. If the rotor position is uncertain, it will directly lead to the failure of the motor to start or a short-term reverse rotation. Therefore, detecting the rotor position of the motor is the key to starting a DC brushless motor. Among the methods for detecting the rotor position, the simplest and most mature one is the method based on back electromotive force detection: this method detects the zero-crossing point of the back electromotive force signal extracted from the motor terminal voltage, and then delays by 30° to obtain commutation information. However, when the motor starts or the speed is very low, the back electromotive force is zero or very small, resulting in the inability to accurately detect the rotor position signal.
[0003] For this reason, in the prior art, such as a DC brushless motor rotor position detection device and its detection method recorded in a patent with the authorization announcement number CN115912801B, a contact method between a conductive component and a resistance ring is adopted. When the rotor rotates, the conductive component rotates synchronously. By measuring the length of the resistance ring connected to the circuit, the angle that the conductive component has rotated from the head end of the resistance ring can be calculated, thereby obtaining the position information of the motor rotor.
[0004] However, during the assembly process of this DC brushless motor, in order to ensure that the conductive coils in the conductive component are in close contact with the resistance ring and the conductive ring respectively, the conductive coils need to be clamped into the resistance ring and the conductive ring. Such an assembly method will greatly increase the labor intensity of the staff and reduce the production efficiency during manual operation. Summary of the Invention
[0005] The purpose of the present invention is to address the above problems and provide a DC brushless motor processing system that can reduce the labor intensity of the staff.
[0006] To achieve the above purpose, the technical solution adopted in the present application is: a DC brushless motor processing system, including a workbench, an assembly area is arranged at the upper end of the workbench, an assembly mechanism and a clamping mechanism are arranged in the assembly area, the clamping mechanism and the assembly mechanism are arranged at intervals along the axial direction of the workpiece, the assembly mechanism includes a bracket, the bracket moves along the axial direction of the workpiece, a rotating part, a driving rod and an assembly driving mechanism are arranged on the bracket, the rotating part is arranged along the axial direction of the workpiece, the rotating part rotates around its axis under the drive of a workpiece rotating motor, and a connecting mechanism for connecting the workpiece is arranged on the rotating part; the driving rod moves along the radial direction of the workpiece, and the driving rod extends towards the clamping mechanism side; the assembly driving mechanism drives a pushing part to move along the axial direction of the workpiece.
[0007] The above DC brushless motor processing system can be used for the assembly of the DC brushless motor described in the authorized announcement number CN115912801B, that is, the DC brushless motor includes a housing, a rotor shaft movably arranged in the middle inside the housing, a measurement body arranged on the rear end cover of the housing, and a module structure arranged at one end of the measurement body away from the housing.
[0008] The measurement body includes a shaft column movably arranged at the rear end of the housing, a conductive component movably arranged on the periphery of the shaft column, a resistance ring and a conductive ring fixedly arranged at the rear end of the housing. One end of the shaft column close to the housing is fixedly connected to the end of the rotor shaft, and the axis of the shaft column and the rotor shaft are collinear. The whole conductive component rotates synchronously with the shaft column. One end of the conductive component is pressed against the inner side surface of the resistance ring, and the other end is pressed against the inner side surface of the conductive ring, electrically connecting the resistance ring and the conductive ring. The head and tail of the resistance ring are insulated and abutted to form a complete circular ring structure. The resistance ring and the conductive ring do not contact each other. Wiring terminals are arranged at the head end of the resistance ring and the periphery of the conductive ring and are connected to the detection circuit. The resistivity of the resistance ring is equal everywhere, and the resistance value between the head end of the resistance ring and the contact point with the conductive component changes with the change of the position of the conductive component.
[0009] The module structure includes a signal detection and conversion module arranged at one end of the measurement body away from the housing. The signal detection and conversion module is used to detect the voltage and circuit current of the part of the resistance ring connected to the detection circuit, and is used to convert the detection signal into the position signal after the conductive component rotates following the shaft column. A positioning shell is fixedly arranged on the rear end cover of the housing, and the resistance ring, the conductive ring and the insulating ring are all fixedly arranged on the inner side wall of the positioning shell.
[0010] The measurement body further includes a positioning block fixedly arranged on the periphery of the shaft column and an elongation block elastically arranged at one end of the positioning block away from the shaft column. The conductive component is arranged at one end of the elongation block away from the positioning block.
[0011] The conductive component includes an insulating column movably arranged inside one end of the elongation block away from the positioning block and a conductive column fixedly arranged in the middle of the periphery of the insulating column. Conductive rings are integrally arranged at both ends of the periphery of the conductive column. One of the conductive rings abuts against the resistance ring, and the other conductive ring abuts against the conductive ring. The cross section of the outer side surface of the conductive ring is an arc structure. The cross sections of the inner side surfaces of the resistance ring and the conductive ring are arc structures with the same radian and are adapted to the cross section of the outer side surface of the conductive ring. An elastic ring is fixedly arranged in the middle of the periphery of the conductive column. An insulating ring is fixedly arranged between the resistance ring and the conductive ring. The outer side surface of the elastic ring is pressed against the inner side surface of the insulating ring.
[0012] One end of the positioning block away from the shaft column is provided with a limiting groove adapted to the elongating block. One end of the elongating block is movably arranged inside the limiting groove and slides inside the limiting groove. A inner groove is provided in the middle of the end of the elongating block close to the limiting groove. A positioning tube is fixedly arranged on the inner wall of the limiting groove. A connecting tube is fixedly arranged on the inner wall of the inner groove. One end of the connecting tube is movably arranged inside one end of the positioning tube. A spring is sleeved on the circumferences 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 arranged on the side of the shaft column away from the positioning block.
[0013] Further, the connecting mechanism includes an inserting part. One end of the inserting part is in key fit with the rotating part and the inserting part moves along the axial direction of the rotating part. The other end of the inserting part is connected to the support. A connecting part for connecting with the workpiece is arranged at one end of the support for the clamping mechanism. Such a design enables that when the support moves towards the workpiece side, the connecting part connects with the workpiece prior to the driving rod, and 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 driving rod, ensuring that the driving rod can push the conductive component towards the inner side of the shaft column, so that the conductive component does not interfere with the installation of the positioning shell.
[0014] Further, to ensure that the workpiece cannot move during the assembly process, the clamping mechanism includes a support seat. Clamping parts are arranged on both sides of the support seat, and the clamping parts on both sides move relatively.
[0015] Further, the clamping mechanism further 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] Further, to improve the automation level, it further includes an identification mechanism. The identification mechanism includes a mounting seat. The mounting seat moves along the radial direction of the workpiece, and a detection and sensing unit is arranged on the mounting seat. The detection and sensing unit is used to detect the positions of conductive rings in the workpiece, etc. When the positioning shell needs to be installed on the machine shell, the driving rod can push the conductive ring towards the inner side of the machine shell, thus ensuring the normal progress of the assembly process and reducing the manual alignment link.
[0017] Further, since there is a certain delay when the identification mechanism works and the connecting mechanism drives the shaft column to stop rotating, etc., there may be a certain deviation between the axis extension line of the conductive component and the driving rod. To ensure the alignment of the driving rod and the conductive component, it further includes an inspection mechanism opposite to the identification mechanism. The inspection mechanism includes a positioning part. The positioning part moves along the radial direction of the workpiece, and the positioning part 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 driving rod.
[0018] Further, the positioning portion includes two positioning rods symmetrically arranged with the axis of the workpiece as the axis. The upper ends of the two positioning rods extend obliquely upward in opposite directions, so that the two positioning rods are opened in a V shape. During the movement of the positioning portion towards the shaft column, the positioning rods abut against the counterweight block to drive the shaft column to rotate.
[0019] Further, to improve the automation level, a feeding portion moving along the radial direction of the workpiece is arranged on the workbench. A placing hole is arranged on the feeding portion, and the axis of the placing hole is in the same direction as the axis of the workpiece, and both ends of the placing hole are open.
[0020] Further, a telescopic positioning mechanism is arranged on the inner wall of the placing hole to ensure that the position of the positioning shell in the placing hole is unified and does not fall out of the placing hole.
[0021] Further, to improve the automation level, a feeding area is arranged on one side of the assembly area at the upper end of the workbench. A positioning shell storage portion is arranged in the feeding area. One end of the positioning shell storage portion is open. A feeding plate is arranged on the far side of the open end in the positioning shell storage portion. The feeding plate moves along the axis of the workpiece under the push of the feeding driving mechanism. The feeding portion moves between the feeding area and the assembly area. When the feeding portion moves to the feeding area, the feeding portion is located on one side of the open end of the positioning shell storage portion.
[0022] The beneficial effects of the present application: When installing components such as the positioning shell onto the casing of a workpiece such as a DC brushless motor, first, the connecting mechanism on the rotating portion is connected to components such as the shaft column in the workpiece. Subsequently, the rotating portion drives the shaft column to rotate, so that the conductive component on the shaft column is aligned with the driving rod. Then, the driving rod is connected to the conductive component and drives the conductive component to move towards one side of the shaft column. In this way, the conductive component does not interfere with the installation of the positioning shell during the installation process, thereby ensuring that the conductive ring can be smoothly snapped into the resistance ring and the conductive ring. This method effectively reduces the labor intensity of workers and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0028] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present application.
[0029] Example 1, as Figures 1 - 4 shown, the specific structure of this embodiment is a DC brushless motor processing system, which is applied to the DC brushless motor described in the patent authorization announcement number CN115912801B to install the positioning shell on the machine shell. The workpiece 4 in this embodiment is the machine shell of the DC brushless motor. At this time, the shaft column 26 in the measurement body has been installed on the rotor shaft, and the positioning block 27, conductive component 30, etc. have also been installed. The connection method of installing the conductive component 30 on the positioning block adopts the elastic mode described in this patent, that is, a limiting groove adapted to the elongating block is opened at one end of the positioning block 27 away from the shaft column 26, one end of the elongating block is movably arranged inside the limiting groove and slides inside the limiting groove. A inner groove is opened in the middle of one end of the elongating block adjacent to the limiting groove. A positioning tube is fixedly arranged on the inner wall of the limiting groove. A connecting tube is fixedly arranged on the inner wall of the inner groove. One end of the connecting tube is movably arranged inside one end of the positioning tube. A spring is sleeved on the circumferences 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. The above connection method enables the conductive component 30 to move radially along the shaft column 26. At the same time, the positioning shell 28 and the machine shell 29 are temporarily fixed by nesting and then fastened by bolts, welding, etc. At the same time, the resistance ring, conductive ring, insulating ring, etc. have been installed on the inner wall of the positioning shell 28.
[0030] A DC brushless motor processing system includes a workbench 1. An assembly area is provided at the upper end of the workbench 1. An assembly mechanism 2 and a clamping mechanism 3 are arranged in the assembly area. The clamping mechanism 3 and the assembly mechanism 2 are arranged at intervals along the axial direction of the workpiece 4. The assembly mechanism 2 includes a bracket 5. The bracket 5 moves along the axial direction of the workpiece 4 under the action of a linear module, an electric push rod, etc. Or a sliding groove is provided at the upper end of the workbench 1, a sliding seat is provided at the lower end of the bracket 5, and the sliding seat is connected to a lead screw in the sliding groove. The lead screw rotates driven by a motor, thereby driving the bracket 5 to move. A rotating part 6, a driving rod 7 and an assembly driving mechanism 8 are arranged on the bracket 5. Among them, the rotating part 6 is arranged along the axial direction of the workpiece. 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 inserting part 11 arranged in the same direction as the rotating part 6. One end of the inserting 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 as it is provided on the side wall of the inserting part 11, and the key is adapted to a sliding groove on the side wall of the receiving groove. The end face of the inserting 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 inserting part 11 is connected to a support. A connecting part 12 for connecting with the workpiece 4 is provided at one end of the support facing the clamping mechanism. The connecting part 12 can be a pneumatic finger, a magnet, etc. When the end face of the shaft column 26 is a smooth plane, the connecting part 12 can be a vacuum chuck, etc.; the rotating part 6 rotates around its axis driven by a workpiece rotating motor 9, and the workpiece rotating motor 9 is installed on the bracket 5.
[0031] The driving rod 7 moves along the radial direction of the workpiece 4. For this purpose, a longitudinal groove, a guide rail, etc. are provided on the bracket 5. The driving rod 7 is adapted to the longitudinal groove and the guide rail, etc. A radial driving mechanism is provided on the bracket 5. The radial driving mechanism adopts a linear module, an electric push rod, etc. The output end of the radial driving mechanism is connected to the driving rod 7. The driving rod 7 extends towards the clamping mechanism 3 side. The distance between the end face of the driving rod 7 on the clamping mechanism 3 side and the clamping mechanism 3 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 prior to the driving rod 7.
[0032] The assembly driving mechanism 8 drives the pushing part 10 to move along the axial direction of the workpiece. The assembly driving mechanism 8 can adopt a hydraulic cylinder, an electric push rod, etc. To increase the contact area between the pushing part 10 and the positioning shell 28, the pushing part 10 can adopt an annular structure.
[0033] The clamping mechanism 3 includes a support base 13. When the workpiece 4 is placed on the support base 13, the axis of the shaft column 26 together with the insulating column thereon is in a horizontal state. Clamping portions 14 are provided on both sides of the support base 13. The clamping portions 14 on both sides are symmetrically arranged with the axis of the shaft column 26 as the axis. At the same time, the clamping portions 14 move radially along the shaft column 26 under the push of an existing linear driving mechanism such as a cylinder or an electric push rod. The clamping mechanism 3 further includes a reference portion 15. The upper end surface of the reference portion 15 is higher than the upper end surface of the support base 13, so that the end surface of the workpiece 4 can abut against the reference portion 15.
[0034] Specific working process: The worker places the workpiece 4 on the upper end of the support base 13 with the shaft column 26 facing the assembling mechanism 2. Then, the clamping portions 14 on both sides of the workpiece 4 move towards the workpiece 4 to fix the workpiece on the support base 13.
[0035] Then, the worker places the positioning shell 28 required for assembling between the assembling mechanism 2 and the clamping mechanism 3 by hand or other means. The positioning shell 28 is coaxially placed with the shaft column 26. After the positioning shell 28 is placed, the bracket 5 moves towards the workpiece 4. During the movement, the connecting portion 12 establishes a temporary connection with the end surface of the shaft column 26 on the workpiece 4 prior to the driving rod 7. After the connection is established, the rotating portion 6 drives the shaft column 26 to rotate, so that the conductive component 30 on the workpiece 4 is aligned with the driving rod 7. At this time, the conductive component 30 is directly above the shaft column 26. Then, the bracket 5 continues to move so that the driving rod 7 can drive the conductive component 30 to move towards the shaft column 26. There are two ways to connect the driving rod 7 and the conductive component 30. One is that since the outer wall of the conductive ring is higher than the extension block, when the driving rod 7 is located above the extension block of the conductive component 30, the conductive component 30 can be driven to move by pressing the extension block. The other is to set the insulating column in the conductive component 30 as an annular structure, so that the driving rod 7 can be inserted into the insulating column, thereby driving the conductive component 30 to move towards the shaft column 26.
[0036] After the conductive component 30 moves, the pushing part 10 moves towards the workpiece 4 under the push of the assembling driving mechanism 8, so as to push the positioning shell 28 onto the workpiece 4. In order to ensure that the positioning shell 28 will not fall off the workpiece 4, an end cover plate is arranged on the end face of the workpiece 4, and a circle of stop edges concentric with the shaft column 26 is arranged on the end cover plate. The side wall of the positioning shell 28 and the side wall of the stop edge are in tight fit. In this way, during assembly, the positioning shell 28 and the stop edge are nested together to ensure that the positioning shell 28 is not easily detached from the workpiece 4. After the positioning shell 28 is installed, the bracket 5 drives the rotating part 6, the driving rod 7 and the assembling driving 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 relative to the shaft column 26, so that the outer side wall of the conductive ring is clamped into the resistance ring and the conductive ring. One conductive ring abuts against the inner wall of the resistance 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, and the worker removes the workpiece 4, and then fixes the positioning shell 28 on the workpiece 4 by bolts, welding, etc.
[0037] Embodiment 2, as Figures 2 - 3 shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1. However, in this embodiment, it further includes an identification mechanism and an inspection mechanism arranged oppositely, and both the identification mechanism and the inspection mechanism are located between the assembling mechanism 2 and the clamping mechanism 3. The identification mechanism includes a mounting seat 16, and the mounting seat 16 moves radially along the workpiece 4 under the push of a linear module or the like. A detection and sensing unit 17 is arranged on the mounting seat 16. The inspection mechanism includes a positioning part 18, and the positioning part 18 moves radially along the workpiece 4 under the action of a linear module, an electric push rod or the like. In this embodiment, the detection and 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 axis of the workpiece 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 column 26 to rotate, since the distance from the outer side wall of the conductive ring in the conductive component 30 to the center point of the shaft column 26 is greater than the distance from the outer side wall of the counterweight to the center point of the shaft column 26. In this way, the detection and sensing unit 17 can adopt a proximity switch, a touch switch, a pressure sensor, etc. The distance from the sensing end of the detection and sensing unit 17 to the center point of the shaft column 26 is adapted to the distance from the conductive ring to the center point of the shaft column 26. When the conductive ring rotates to the position of the detection and sensing unit 17, the detection and sensing unit 17 sends a detection signal to the control system. After receiving the signal, the control system analyzes the detection signal and then outputs a control signal to control the workpiece rotation motor 9 that drives the rotation part 6 to stop working. Affected by the feedback mechanism, etc., at this time, the conductive component 30 may not be aligned with the driving rod 7. Therefore, after the workpiece rotation motor 9 stops working, the positioning part 18 rises, and the positioning rod 19 contacts the counterweight, thereby rotating the shaft column 26 so that the counterweight rotates to directly below the shaft column 26, that is, the conductive component 30 is aligned with the driving rod 7. After the position of the conductive component 30 is corrected, the driving rod 7 establishes a connection with the conductive component 30 again. After the connection is established, the positioning part 18 and the detection and sensing unit 17 move away from the workpiece 4 to facilitate the installation of the positioning shell 28.
[0040] Embodiment 3, as Figures 1 - 2 shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, a feeding part 20 that moves along the radial direction of the workpiece is provided on the workbench 1, and the driving mode of the feeding part 20 refers to the driving mechanism of the reference bracket 5. A placing hole 21 is provided on the feeding part 20, and the axis of the placing hole 21 is in the same direction as the axial direction of the workpiece 4. Both ends of the placing hole 21 are open, and the inner diameter of the placing 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 placing hole 21. The telescopic positioning mechanism 22 can adopt a spring positioning pin, that is, grooves are annularly arranged on the inner wall of the placing hole 21, 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. One end of the positioning pin located in the groove is connected to the inner end face of the groove through a positioning spring. Or the telescopic positioning mechanism 22 is directly made of materials such as rubber and silica gel to be able to clamp the positioning shell 28. On the upper end of the workbench 1, a feeding area is provided on one side of the assembly area, and a positioning shell storage part 23 is provided in the feeding area. One side end of the positioning shell storage part 23 is open, and a feeding plate 24 is provided on the far side of the open end in the positioning shell storage part 23. The feeding plate 24 moves along the axial direction of the workpiece under the push of the feeding driving mechanism 25. The feeding driving mechanism 25 can adopt an electric push rod, a linear module, etc. The feeding part 20 moves between the feeding area and the assembly area. When the feeding part 20 moves to the feeding area, the feeding part 20 is located on one side of the open end of the positioning shell storage part 23. At the same time, the upper end of the positioning shell storage part 23 is also open to facilitate placing the positioning shell 28 therein.
[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 should ensure that the positioning shell 28 can move from the positioning shell storage part 23 into the placing hole 21.
[0042] Then the feeding plate 24 moves towards the feeding part 20 to push the outermost positioning shell in the positioning shell storage part 23 into the placing hole 21 of the feeding part 20. Then the feeding part 20 moves with the positioning shell 28 to the assembly area and makes the positioning shell 28 coaxial with the shaft column 26. After the movement of the positioning shell 28 is completed, the installation of the positioning shell 28 starts according to the working process of Embodiment 1.
