Description

Technical Field

[0001] The invention relates to the field of assembly equipment, in particular to a brushless DC motor and a processing system thereof. Background Art

[0002] The brushless DC motor uses a permanent magnet as the rotor. If the rotor position is uncertain, it will directly lead to motor starting failure or short-term reversal. Therefore, detecting the motor rotor position is the key to starting the brushless DC motor. Among the methods for detecting the rotor position, the simplest and most mature method is based on back-EMF detection: this method detects the zero-crossing point of the back-EMF signal extracted from the motor terminal voltage and then delays it by 30° to obtain the commutation information. However, when the motor starts or the speed is very low, the back-EMF is zero or very small, making it impossible to accurately detect the rotor position signal.

[0003] To this end, the prior art, such as a DC brushless motor rotor position detection device and detection method described in the patent with authorization announcement number CN115912801B, adopts a contact method between a conductive component and a resistance ring. When the rotor rotates, the conductive component rotates synchronously. By measuring the length of the resistance ring connected to the circuit, the angle of the conductive component from the head end of the resistance ring can be calculated, thereby obtaining the position information of the motor rotor.

[0004] However, in the assembly process of the brushless DC motor, in order to ensure that the conductive ring in the conductive assembly is in close contact with the resistance ring and the conductive ring respectively, the conductive ring needs to be inserted into the resistance ring and the conductive ring. This assembly method greatly increases the labor intensity of the staff and reduces production efficiency when manually operated. Summary of the invention

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

[0011] The conductive component includes an insulating column movably arranged on the inner side of one end of the elongation block away from the positioning block, and a conductive column fixedly arranged in the middle of the circumference of the insulating column. Conductive rings are integrally arranged at both ends of the circumference of the conductive column, one of the conductive rings is against the resistance ring, and the other conductive ring is against the conductive ring; the cross-section of the outer side of the conductive ring is an arc structure, and the cross-section of the inner side of the resistance ring and the conductive ring is an arc structure with the same curvature, and is adapted to the cross-section of the outer side of the conductive ring; an elastic ring is fixedly arranged in the middle of the circumference of the conductive column, and an insulating ring is fixedly arranged between the resistance ring and the conductive ring, and the outer side of the elastic ring and the inner side of the insulating ring are pressed together.

This design allows the connection portion to connect to the workpiece before the drive rod when the bracket moves toward the workpiece, and then the connection portion 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, ensuring that the drive rod can push the conductive component to move inwardly of the shaft column, so that the conductive component will not interfere with the installation of the positioning shell.

[0017] Furthermore, since there is a certain delay when the identification mechanism works and the connection mechanism stops driving the shaft column to rotate, the conductive component may deviate from the extended line of the axis of the driving rod.

[0019] Furthermore, in order to improve the level of automation, a feeding part that moves radially along the workpiece is provided on the workbench, and a placement hole is provided on the feeding part. The axis of the placement hole is in the same direction as the axial direction of the workpiece, 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 position of the positioning shell in the storage hole remains uniform and does not fall out of the storage hole.

Subsequently, the rotating part drives the shaft column to rotate so that the conductive component on the shaft column is aligned with the driving rod. Next, the driving rod is connected to the conductive component and drives the conductive component to move toward one side of the shaft column. In this way, the conductive component will not interfere with the installation of the positioning shell during the installation process, thereby ensuring that the conductive ring can be smoothly inserted into the resistance ring and the conductive ring. This method effectively reduces the labor intensity of the staff and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A brushless DC 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 provided in the assembly area, the clamping mechanism 3 and the assembly mechanism 2 are arranged at intervals along the axial direction of a 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 slide groove is provided at the upper end of the workbench 1, a sliding seat is provided at the lower end of the bracket 5, the sliding seat is connected to the screw rod in the slide groove, the screw rod rotates under the drive of the motor, thereby driving the bracket 5 to move. The bracket 5 is provided with a rotating part 6, a driving rod 7 and an assembly driving mechanism 8. The rotating part 6 is arranged along the axial direction of the workpiece, one end of the rotating part 6 is connected to the bearing on the bracket 5, and the other end of the rotating part 6 is connected to the 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 arranged 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 the insertion part 11 is arranged on the side wall, 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 through 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 with the workpiece 4 at one end of the clamping mechanism, the connecting part 12 can adopt pneumatic clamping fingers, magnets, etc., when the end face of the shaft column 26 is a smooth plane, the connecting part 12 can adopt a vacuum suction cup, etc.; the rotating part 6 rotates around its axis under the drive of the workpiece rotating motor 9, and the workpiece rotating motor 9 is installed on the bracket 5.

[0031] The driving rod 7 moves radially along the workpiece 4. For this purpose, the bracket 5 is provided with a longitudinal groove, a guide rail, etc. 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 toward the side of the clamping mechanism 3. The distance between the driving rod 7 and the clamping mechanism 3 on the side end face of the clamping mechanism 3 is greater than the distance between the connecting portion 12 and the clamping mechanism 3 under normal conditions, so that the connecting portion 12 contacts the workpiece 4 before the driving rod 7.

[0032] The assembly drive mechanism 8 drives the push part 10 to move axially along the workpiece. The assembly drive mechanism 8 can adopt 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 adopt a circular ring structure.

[0033] The clamping mechanism 3 includes a support seat 13. The support seat 13 is arranged so that when the workpiece 4 is placed on the support seat 13, the axis of the shaft column 26 and the insulating column thereon are in a horizontal state. Clamping parts 14 are arranged on both sides of the support seat 13. The clamping parts 14 on both sides are symmetrically arranged with the axis of the shaft column 26 as the axis. At the same time, the clamping parts 14 move radially along the shaft column 26 under the push of existing linear drive mechanisms such as cylinders and 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 seat 13, so that the end surface of the workpiece 4 can abut against the reference part 15.

[0034] Specific working process: the staff places the workpiece 4 on the upper end of the support seat 13 with the shaft column 26 facing the assembly mechanism 2, and then the clamping parts 14 on both sides of the workpiece 4 move toward the workpiece 4 to fix the workpiece on the support seat 13.

[0035] Then the staff places the positioning shell 28 required for assembly between the assembly mechanism 2 and the clamping mechanism 3 by hand or other means, and the positioning shell 28 is placed coaxially with the shaft column 26. After the positioning shell 28 is placed, the bracket 5 moves toward the workpiece 4. During the movement, the connecting portion 12 establishes a temporary connection with the end face of the shaft column 26 on the workpiece 4 before 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 located directly above the shaft column 26, and then the bracket 5 continues to move so that the driving rod 7 can drive the conductive component 30 to move toward the shaft column 26. The driving rod 7 and the conductive component 30 can be connected in the following two ways: one is that the outer wall of the conductive ring is higher than the extension block, and the driving rod 7 is located above the extension block of the conductive component 30 at this time, and the conductive component 30 can be driven to move by pressing the extension block; the second is to set the insulating column in the conductive component 30 as a ring structure, so that the driving rod 7 can be inserted into the insulating column, thereby driving the conductive component 30 to move toward the shaft column 26.

[0036] After the conductive assembly 30 moves, the pusher 10 moves toward the workpiece 4 under the push of the assembly drive mechanism 8, thereby pushing 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 provided on the end face of the workpiece 4, and a circle of stop edges concentric with the shaft column 26 is provided on the end cover plate. The side wall of the positioning shell 28 is tightly matched with the side wall of the stop edge, so that during assembly, the positioning shell 28 and the stop edge are nested together to ensure that the positioning shell 28 is not easy to fall off 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 assembly drive mechanism 8 away from the workpiece. At this time, under the action of the spring, the conductive ring in the conductive assembly 30 moves toward the outside of the shaft column 26, so that the outer wall of the conductive ring is stuck in the resistance ring and the conductive ring, one of the conductive rings is against the inner wall of the resistance ring, and the other conductive ring is against the inner wall of the conductive ring. Then the clamping part 14 is away from the workpiece, the staff removes the workpiece 4, and then fixes the positioning shell 28 on the workpiece 4 by bolts, welding, etc.

[0037] Embodiment 2, as Figure 2-Figure 3 As shown, the other structures and working processes of this embodiment are the same as those of embodiment 1, but in this embodiment, it also includes an identification mechanism and an inspection mechanism that are relatively arranged, and both the identification mechanism and the inspection mechanism are located between the assembly 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 the linear module, etc., and a detection sensor unit 17 is arranged on the mounting seat 16. The inspection mechanism includes a positioning portion 18, and the positioning portion 18 moves radially along the workpiece 4 under the action of the linear module, the electric push rod, etc. In this embodiment, the detection sensor unit 17 is located directly above the shaft column 26, and the positioning portion 18 is located directly below the shaft column 26.

[0038] The positioning portion 18 includes two positioning rods 19 symmetrically arranged around the axis of the workpiece, 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, the distance from the outer wall of the conductive ring in the conductive component 30 to the center of the shaft column 26 is greater than the distance from the outer wall of the counterweight to the center of the shaft column 26. In this way, the detection sensor unit 17 can adopt a proximity switch, a touch switch, a pressure sensor, etc. The distance from the sensing end of the detection sensor unit 17 to the center of the shaft column 26 is adapted to the distance from the conductive ring to the center of the shaft column 26. When the conductive ring rotates to the detection sensor unit 17, the detection sensor 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 control the workpiece rotating motor 9 that drives the rotating part 6 to rotate to stop working. Affected by the feedback mechanism, the conductive component 30 may not be aligned with the driving rod 7 at this time. Therefore, after the workpiece rotating 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 the bottom of 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 is connected to the conductive component 30 again. After the connection is established, the positioning portion 18 and the detection sensor unit 17 are away from the workpiece 4 to facilitate the installation of the positioning shell 28.

[0040] Embodiment 3, as Figure 1-Figure 2 As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, the workbench 1 is provided with a feeding part 20 that moves along the radial direction of the workpiece, and the driving method of the feeding part 20 refers to the driving mechanism of the bracket 5. The feeding part 20 is provided with a storage hole 21, the axis of the storage hole 21 is in the same direction as the axial direction of the workpiece 4, the two ends of the storage hole 21 are open, and the inner diameter of the storage 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 storage hole 21, and the telescopic positioning mechanism 22 can adopt a spring positioning pin, that is, a groove is provided in an annular array on the inner wall of the storage hole 21, and the positioning pin is inserted into the groove, and one end of the positioning pin extending out of the groove is provided as a ball head, and the end of the positioning pin located in the groove is connected to the inner end surface of the groove through a positioning spring, or the telescopic positioning mechanism 22 is directly made of rubber, silicone and other materials to clamp the positioning shell 28. A loading area is provided at the upper end of the workbench 1 on one side of the assembly area, and a positioning shell storage portion 23 is provided in the loading area. One side end of the positioning shell storage portion 23 is open, and a loading plate 24 is provided in the positioning shell storage portion 23 on the far side of the open end. The loading plate 24 moves along the axial direction of the workpiece under the push of a loading drive mechanism 25. The loading drive mechanism 25 can adopt an electric push rod, a linear module, etc. The feeding portion 20 moves between the loading area and the assembly area. When the feeding portion 20 moves to the loading area, the feeding portion 20 is located on the open end side of the positioning shell storage portion 23, and at the same time, the upper end of the positioning shell storage portion 23 is also set to be open, so as to facilitate the placement of the positioning shell 28 therein.

[0041] Specific working process: the feeding part 20 first moves to the open side end 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 needs to ensure that the positioning shell 28 can move from the positioning shell storage part 23 to the storage hole 21.

[0042] Then the loading plate 24 moves toward the feeding part 20, and pushes the outermost positioning shell in the positioning shell storage part 23 into the storage hole 21 of the feeding part 20. Then the feeding part 20 carries the positioning shell 28 and moves it to the assembly area, and makes the positioning shell 28 coaxial with the shaft column 26. After the positioning shell 28 is moved, the installation of the positioning shell 28 begins according to the working process of Example 1.
