Description

Technical Field

[0001] The invention relates to the technical field of motor assembly of household electrical appliances, and in particular to a motor shaft rotation orientation device and a motor shaft rotation orientation equipment. Background Art

[0002] In the home appliance industry, electrical products with head shaking and steering functions are inevitably inseparable from claw-pole permanent magnet synchronous motors. Claw-pole permanent magnet synchronous motors have large output torque, low price, and wide application scenarios. Claw-pole permanent magnet synchronous motors are usually equipped with some components to achieve the head shaking and steering of specific components, such as the head or body. In the actual production and assembly process, there are usually requirements for the initial direction of the claw-pole permanent magnet synchronous motor shaft. For example, the initial direction of the rotating shaft of each claw-pole permanent magnet synchronous motor is required to be unified, which facilitates continuous assembly in the subsequent process and improves assembly efficiency.

[0003] At present, the technical solution for unifying the initial direction of the claw-pole permanent magnet synchronous motor shaft generally directly adopts the orientation method of manually rotating the claw-pole permanent magnet synchronous motor shaft. However, since manual operation cannot rotate the claw-pole permanent magnet synchronous motor shaft at a constant speed and force, the claw-pole permanent magnet synchronous motor shaft often rotates too fast and is subjected to too much force, resulting in cracks in the internal gears of the claw-pole permanent magnet synchronous motor, which in turn causes noise, jitter, and even failure of the shaking of the head in the final product.

[0004] Therefore, it is necessary to provide a claw-pole permanent magnet synchronous motor shaft position adjustment scheme to solve the technical problems of excessive speed and excessive force of the claw-pole permanent magnet synchronous motor during manual operation. Summary of the invention

[0005] In view of the defects of the above prior art, the present invention provides a motor shaft rotation orienting device and a motor shaft rotation orienting equipment to solve the technical problems of excessively fast motor shaft speed and excessive force in the prior art.

[0006] The present invention is implemented by the following technical solutions:

[0007] A motor shaft rotation and orientation device comprises a bracket, a carrier, a moving mechanism, a sleeve and a rotating mechanism; the carrier is arranged on the bracket and is used to load the motor; the moving mechanism is arranged on the bracket; the sleeve is connected to the moving mechanism and is opposite to the carrier, and the sleeve is driven by the moving mechanism to move toward and away from the carrier along a straight line trajectory, and the sleeve has a contour hole adapted to the shape of the end of the motor shaft, and in the process of the sleeve moving toward the carrier, the contour hole is sleeved on the end of the motor shaft; the rotating mechanism is connected to the sleeve, and before the contour hole is sleeved on the end of the motor shaft, the sleeve is driven by the rotating mechanism to rotate, so that the position of the contour hole corresponds to the end position of the motor shaft, and after the contour hole is sleeved on the end of the motor shaft, the sleeve is driven by the rotating mechanism to rotate, so that the sleeve drives the motor shaft to rotate.

[0008] In one embodiment, the moving mechanism includes a telescopic driving member, a mounting frame and a rotating seat; the mounting frame is fixedly connected to the output end of the telescopic driving member; the rotating seat is rotatably disposed on the mounting frame; the sleeve is disposed on the rotating seat and rotates together with the rotating seat; the rotating mechanism is connected to the sleeve through the rotating seat.

[0009] In one embodiment, the rotating seat is provided with an insertion hole extending along a straight trajectory, and the sleeve can be inserted into the insertion hole so as to move back and forth along the straight trajectory relative to the insertion hole; the moving mechanism also includes an elastic member, which connects the rotating seat and the sleeve. When the sleeve moves away from the carrier along the straight trajectory relative to the insertion hole, the elastic member is squeezed by the sleeve and the rotating seat and is in a compressed state.

[0010] In one embodiment, the rotating seat includes a main body and a coupling. The main body is rotatably arranged on the mounting frame through a bearing. The coupling is fixedly connected to the side of the main body facing away from the carrier. The output end of the rotating mechanism is fixedly connected to the coupling.

[0011] In one embodiment, the plug hole is opened in the main body, and the port of the plug hole facing away from the carrier is opposite to the coupling; the elastic member is a linear spring, which is located in the plug hole, and its two ends are respectively fixed to the sleeve and the coupling.

[0012] In one embodiment, the plug hole is prism-shaped, and the shape of the sleeve matches the shape of the plug hole.

[0013] In one embodiment, it also includes a controller and a force sensor. The output end of the telescopic drive component is connected to the mounting frame through the force sensor, and data about the force applied by the mounting frame is collected by the force sensor. The telescopic drive component, the rotation drive mechanism and the force sensor are all electrically connected to the controller. When the controller receives a signal about the data fed back by the force sensor, the controller controls the rotation drive mechanism and the telescopic drive mechanism to work according to the signal.

[0014] In one embodiment, the rotating seat is fixedly connected with a sensing sheet, the mounting bracket is provided with a sensor for cooperating with the sensing sheet, and the sensor is electrically connected with the controller.

Through the above-mentioned manner, the present invention can complete the process of adjusting the position of the motor shaft by a machine instead of manually. Based on the uniform and controllable force of the machine, the rotating mechanism of the present invention drives the motor shaft to rotate at a constant speed through the sleeve, so that the motor shaft is subjected to a relatively uniform force, thereby avoiding the technical defects of excessive force on the motor shaft and excessive rotation speed in the manual operation scheme, thereby damaging the internal structure of the motor.

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0034] The words expressing position and direction described in the present invention are all explained by taking the accompanying drawings as examples, but they can be changed as needed, and all changes are included in the protection scope of the present invention.

[0035] See also Figure 1 and Figure 2 , this embodiment discloses a motor shaft rotation orientation device, which can be used to adjust the position of the motor shaft, and is particularly suitable for adjusting the position of the claw-pole permanent magnet synchronous motor shaft. The motor shaft rotation orientation device of this embodiment includes an electric control cabinet 10, a frame 20, a control panel, and three motor shaft rotation orientation devices 30. The frame 20 is arranged on the top surface of the electric control cabinet 10, and the three motor shaft rotation orientation devices 30 are arranged in parallel on the top surface of the electric control cabinet 10 and are located inside the frame 20. An open operation window is provided on the front side of the frame 20. The operator assembles the motor whose shaft position is to be adjusted on the motor shaft rotation orientation device 30 from the position of the operation window, and the motor shaft rotation orientation device 30 adjusts the motor shaft position. After the adjustment is completed, the operator removes the motor from the position of the operation window. In other embodiments, the number of motor shaft rotation orientation devices 30 can be one, two or more.

[0036] In this embodiment, the control panel is arranged above the frame 20, and the operator can control the operation of the entire device through the control panel. The frame 20 is also provided with a warning light, a start button, a reset button and an emergency button. The start button and the reset button are used to control the device to start working and reset the device respectively. When the motor shaft rotation orientation device 30 has an abnormal operation, the warning light will light up to warn, and the operator can stop the device by pressing the emergency button.

[0037] See also Figure 3-Figure 6 In this embodiment, the motor shaft rotation orientation device 30 includes a bracket, a carrier 32 , a moving mechanism 33 , a sleeve 31 and a rotating mechanism 34 .

[0038] The bracket is fixed to the top surface of the electric control cabinet 10. The carrier 32 is arranged on the bracket and is used to load the motor; specifically, the carrier 32 includes a loading slot for loading the motor body 333, the motor is placed in the loading slot, and the position of the motor is defined by the loading slot; of course, in other embodiments, the carrier 32 can also be other structural shapes, as long as it can load and define the position of the motor, and the specific structural shape of the carrier 32 is not limited here.

[0039] The moving mechanism 33 is disposed on the bracket. The sleeve 31 is connected to the moving mechanism 33 and is opposite to the carrier 32. The sleeve 31 is driven by the moving mechanism 33 to move toward and away from the carrier 32 along the straight track 80. Specifically, the sleeve 31 is located above the carrier 32 at intervals. In other embodiments, the carrier 32 may also be located above the sleeve 31, or the sleeve 31 and the carrier 32 may be arranged at intervals in a transverse manner.

[0040] The sleeve 31 has a profiled hole that matches the shape of the end of the motor shaft, and the profiled hole is sleeved on the end of the motor shaft during the movement of the sleeve 31 toward the carrier 32. In one feasible solution, the radial cross section of the end of the motor shaft is D-shaped, and the radial cross section of the profiled hole is also D-shaped.

[0041] The rotating mechanism 34 is connected to the sleeve 31. Before the profiling hole is sleeved on the end of the motor shaft, the sleeve 31 is driven to rotate by the rotating mechanism 34 to adjust the position of the sleeve 31 so that the position of the profiling hole of the sleeve 31 corresponds to the end position of the motor shaft. After the profiling hole is sleeved on the end of the motor shaft, the sleeve 31 is driven to rotate by the rotating mechanism 34 so that the sleeve 31 drives the motor shaft to rotate. Compared with the prior art, the present embodiment can complete the process of adjusting the position of the motor shaft by a machine instead of manually. Based on the uniform and controllable force of the machine, the rotating mechanism 34 of the present embodiment drives the motor shaft to rotate at a constant speed through the sleeve 31, so that the motor shaft is subjected to a relatively uniform force, avoiding the technical defects of excessive force on the motor shaft and excessive rotation speed in the manual operation scheme, which damages the internal structure of the motor.

[0042] In this embodiment, the mobile mechanism 33 includes a telescopic drive member 331, a mounting frame 332 and a rotating seat. Among them, the telescopic drive member 331 is a cylinder. In other embodiments, the telescopic drive member 331 can be a linear module, a screw mechanism, or other components that can output linear telescopic motion. The telescopic drive member 331 of this embodiment is installed on the bracket, and its output end faces downward. The mounting frame 332 is fixed to the output end of the telescopic drive member 331. The rotating seat is rotatably arranged on the mounting frame 332. The sleeve 31 is arranged on the rotating seat and rotates together with the rotating seat. The rotating mechanism 34 is connected to the sleeve 31 through the rotating seat. When the rotating mechanism 34 drives the rotating seat to rotate, the rotating seat drives the sleeve 31 to rotate. In the above scheme, the rotating mechanism 34 is directly connected to and drives the sleeve 31 through the rotating seat of the mobile mechanism 33. Therefore, there is no need to set up additional components to connect and drive the sleeve 31, which can effectively improve the compactness of the structure of the equipment and reduce the number of equipment parts.

[0043] In this embodiment, the rotating seat is provided with a plug-in hole extending along the linear track 80, and the sleeve 31 can be inserted into the plug-in hole so as to reciprocate along the linear track 80 relative to the plug-in hole. The linear track 80 extends in the up-down direction, and the sleeve 31 and the carrier 32 are both located on the linear track 80. In other embodiments, the extension direction of the linear track 80 can be changed according to the actual arrangement of the sleeve 31 and the carrier 32.

[0044] The moving mechanism 33 of this embodiment further comprises an elastic member, which connects the rotating seat and the sleeve 31 . When the sleeve 31 moves away from the carrier 32 along the straight track 80 relative to the plug hole, the elastic member is squeezed by the sleeve 31 and the rotating seat and is in a compressed state.

[0045] In an actual application scenario, when the moving mechanism 33 drives the sleeve 31 to move downward toward the carrier 32, when the bottom end of the sleeve 31 abuts against the end of the motor shaft carried by the carrier 32, the position of the contour hole of the sleeve 31 does not match the position of the end of the motor shaft, and the contour hole cannot be set on the end of the motor shaft. Therefore, the end of the motor shaft generates an upward force on the bottom end of the sleeve 31. Since the sleeve 31 can move up and down along the straight track 80 relative to the plug hole, when the force is applied to the sleeve 31, the sleeve 31 can adaptively evade upward, preventing the sleeve 31 from rigidly contacting the end of the motor shaft and damaging the motor. When the sleeve 31 adaptively evades upward, the elastic member is squeezed by the sleeve 31 and the rotating seat and is in a compressed state. The deformation elastic force of the elastic member causes the sleeve 31 to form a tendency to move downward. At this time, the rotating mechanism 34 drives the sleeve 31 to rotate by the rotating seat, so that the position of the sleeve 31 changes, until the position of the profile hole of the sleeve 31 matches the position of the end of the motor shaft, and under the deformation elastic force of the elastic member, the sleeve 31 moves downward and is sleeved on the end of the motor shaft. Through the above-mentioned method, the profile hole of the sleeve 31 can be automatically matched and sleeved on the end of the motor shaft, and the sleeve process of the profile hole and the end of the motor shaft is fully automated, which improves work efficiency.

[0046] In this embodiment, the rotating seat includes a main body 333 and a coupling 334. The main body 333 is rotatably arranged on the mounting frame 332 through a bearing; the coupling 334 is fixedly connected to the side of the main body 333 facing away from the carrier 32; and the output end of the rotating mechanism 34 is fixedly connected to the coupling 334. Specifically, the mounting frame 332 includes a bottom plate 3323, a top plate 3321, a side plate 3322 and a cylindrical member 3324. The side plate 3322 is vertically arranged, and the bottom plate 3323 and the top plate 3321 are respectively fixedly connected to the bottom side and the top side of the side plate 3322. The cylindrical member 3324 is fixedly connected to the bottom wall of the bottom plate 3323, and the bearing is arranged in the cylindrical member 3324. The coupling 334 passes through the bottom plate 3323, and the fixed part of the coupling 334 is fixedly connected to the bottom plate 3323. The top end of the rotating shaft part of the coupling 334 is located between the top plate 3321 and the bottom plate 3323, and the bottom end of the rotating part of the coupling 334 is located in the cylindrical member 3324. The rotating mechanism 34 can be a servo motor 341, and the main body 333 of the servo motor 341 is fixedly connected to the top plate 3321 through a fastener. The output end of the servo motor 341 passes through the top plate 3321 downward and is fixedly connected to the top end of the coupling 334. Specifically, the output end of the servo motor 341 is fixedly connected to the top end of the rotating part of the coupling 334. The top end of the main body 333 is fixedly connected to the bottom end of the coupling 334. Specifically, the top end of the main body 333 is fixedly connected to the bottom end of the rotating part of the coupling 334, and the main body 333 is inserted into the inner ring of the bearing. When the output end of the servo motor 341 rotates, the output end of the servo motor 341 drives the main body 333 to rotate through the rotating part of the coupling 334. The coupling 334 can be a common component on the market, which generally includes a fixed part and a rotating part rotatably inserted in the fixed part. As for its more specific structure and working principle, it belongs to the prior art, so this embodiment does not elaborate on the specific structure and working principle of the coupling 334.

[0047] In this embodiment, the plug-in hole is provided in the main body 333, and the port of the plug-in hole facing away from the carrier 32 is opposite to the coupling 334. The elastic member is a linear spring, which is located in the plug-in hole, and its two ends are respectively fixed to the sleeve 31 and the coupling 334. The sleeve 31 is hung in the plug-in hole by the linear spring to prevent the sleeve 31 from falling off from the plug-in hole. This scheme does not need to set an additional connection structure to limit the sleeve 31 in the plug-in hole, so there are fewer parts and a simpler structure. Of course, in other embodiments, the sleeve 31 can also be limited in the plug-in hole by other feasible technical solutions. For example, the bottom port of the plug-in hole can be designed with an annular boss extending radially inwardly along the plug-in hole, and a shoulder structure extending radially outwardly along the sleeve 31 is set at the top of the sleeve 31. The annular boss supports the shoulder structure, so that the top of the sleeve 31 can be hung in the plug-in hole. In this solution, the two ends of the linear spring do not need to be fixedly connected to the sleeve 31 and the coupling 334. The linear spring can be directly placed in the plug-in hole so that its two ends abut against the sleeve 31 and the coupling 334 respectively. This solution omits the process of connecting the linear spring to the sleeve 31 and the coupling 334, thereby simplifying the overall assembly process.

[0048] In other embodiments, the elastic member may also be a member having good deformation elasticity, such as a rubber block or a silicone block.

[0049] In this embodiment, the shape of the plug hole is prismatic, and the shape of the sleeve 31 is adapted to the shape of the plug hole. When the sleeve 31 is inserted into the plug hole, the sleeve 31 cannot rotate relative to the plug hole. Therefore, when the rotating seat rotates, the sleeve 31 can be driven to rotate synchronously. In other embodiments, the sleeve 31 can also slide up and down relative to the plug hole and rotate synchronously with the rotating seat through other feasible technical solutions. For example, the sleeve 31 can be slidably connected to the hole wall of the plug hole through a slide rail structure, so that the sleeve 31 can slide up and down relative to the plug hole and can also rotate synchronously with the rotating seat.

[0050] In this embodiment, the motor shaft rotation orientation device 30 also includes a controller and a force sensor 60. The output end of the telescopic drive member 331 is connected to the mounting frame 332 through the force sensor 60, and the force sensor 60 collects data about the force applied by the mounting frame 332. The telescopic drive member 331, the rotation drive mechanism and the force sensor 60 are all electrically connected to the controller. When the controller receives the signal about the data fed back by the force sensor 60, the controller controls the rotation drive mechanism and the telescopic drive mechanism to work according to the signal. Among them, the controller can be a PLC controller or other common micro control modules. The controller is arranged in the electric control cabinet 10 and is electrically connected to the control panel. The operator can input control instructions to the controller through the control panel, and the controller can display the working status information of the equipment on the control panel for the operator to check. The force sensor 60 can be a commonly used sensing component for detecting the magnitude of force, which belongs to the prior art, so this embodiment does not limit its specific model, structure and installation method.

[0051] In an actual application scenario, the moving mechanism 33 drives the sleeve 31 to move downward toward the carrier 32. Before the bottom end of the sleeve 31 contacts the end of the motor shaft carried by the carrier 32, the operator resets the force information of the force sensor 60 through the control panel, so that the force data of the force sensor 60 displayed on the control panel is zero. When the sleeve 31 moves downward and contacts the end of the motor shaft, the position of the contoured hole of the sleeve 31 does not match the position of the end of the motor shaft, and the contoured hole cannot be mounted on the end of the motor shaft. The end of the motor shaft generates an upward force on the bottom end of the sleeve 31, so that the sleeve 31 adaptively moves upward relative to the plug-in hole. At this time, the elastic member is in a compressed state, and the upward force exerted by the end of the motor shaft on the bottom end of the sleeve 31 is transmitted to the force sensor 60 through the elastic member, the coupling 334, and the mounting bracket 332. The force sensor 60 generates a first force signal. 0 transmits the first force signal to the controller, and the controller displays the data related to the first force signal through the control panel for the operator to view. At the same time, based on the first force signal, the controller controls the servo motor 341 of the rotating mechanism 34 to rotate for the first time after a specific delay time (for example, 0.1S), thereby driving the sleeve 31 to rotate until the position of the profiling hole of the sleeve 31 is matched with the end position of the motor shaft, so that the profiling hole can be downwardly sleeved on the end of the motor shaft. Correspondingly, the sleeve 31 moves downward under the main driving action of the deformation elastic force of the elastic member. Since the end of the motor shaft stops applying an upward force to the sleeve 31 or reduces the upward force applied to the sleeve 31 at this time, the force on the force sensor 60 changes, and the force sensor 60 generates a second force signal, and feeds the second force signal back to the controller. The controller displays the data related to the second force signal through the control panel for the operator to check. At the same time, the controller compares the first force signal and the second force signal, and calculates the difference between the two forces. If the difference is within the expected value range, the controller determines that the contour hole of the sleeve 31 has been sleeved on the end of the motor shaft, and then the controller controls the servo motor 341 of the rotating mechanism 34 to rotate for the second time after a certain delay (for example, 0.1S), thereby driving the sleeve 31 to rotate, and the sleeve 31 drives the motor shaft, thereby adjusting the position of the motor shaft. In the above scenario, under the control of the controller, the second rotation process of the servo motor 341 includes a speed-up rotation stage and a uniform speed rotation stage, wherein the speed-up rotation stage is specifically manifested as: starting from zero speed, slowly accelerating to a preset rotation speed at a constant speed-up rate. The uniform rotation stage is specifically characterized by: after the speed-up rotation stage, uniform rotation is performed at a preset rotation speed. The aforementioned second rotation scheme can prevent the motor shaft from being driven quickly, thereby preventing the internal components of the motor from being damaged due to sudden and large forces.

[0052] In a special scenario, if the difference between the first force signal and the second force signal is not within the expected difference range, the controller determines that the contoured hole of the sleeve 31 is not completely mounted on the end of the motor shaft, and the controller generates an abnormal signal, and displays the abnormal signal through the control panel for the operator to review, and controls the prompt light to light up to warn the operator to check the specific situation. In addition, the controller also controls the rotating mechanism 34 and the moving mechanism 33 to stop working.

[0053] In a special scenario, if the force sensor 60 does not generate the second force signal for a long time, for example, after the servo motor 341 of the rotating mechanism 34 drives the sleeve 31 to rotate 360°, it still does not generate the second force signal, indicating that the force on the force sensor 60 has not changed, and the contoured hole of the sleeve 31 cannot be mounted on the end of the motor shaft. At this time, the controller generates an abnormal signal and displays the abnormal signal through the control panel for the operator to review, and controls the prompt light to light up to remind the operator to check the specific situation. In addition, the controller also controls the rotating mechanism 34 to stop working, and controls the moving mechanism 33 to drive the sleeve 31 to lift up and away from the carrier 32.

[0054] Through the above-mentioned scheme design, this embodiment can automatically complete the process of sleeve 31 being set on the end of the motor shaft and safely driving the motor shaft to rotate, with high work efficiency and low motor damage rate. In addition, this embodiment can also automatically detect abnormal working conditions and make adaptive action adjustments to effectively improve work quality.

[0055] In this embodiment, the rotating seat is fixed with a sensing piece 72; specifically, the sensing piece 72 is fixed to the outer wall of the main body 333 of the rotating seat. In this embodiment, the mounting frame 332 is provided with a sensor 71 for matching with the sensing piece 72. Specifically, the sensor 71 is fixed to the cylindrical component 3324 of the mounting frame 332, and the sensor 71 is electrically connected to the controller. Among them, the sensor 71 can be a common slot-type photoelectric sensor on the market, and the sensing piece 72 is a component that matches the slot-type photoelectric sensor. After the contoured hole of the sleeve 31 is sleeved on the end of the motor shaft, the main body 333 drives the sleeve 31 to rotate and drives the induction sheet 72 to move, and the sleeve 31 drives the motor shaft to rotate. When the induction sheet 72 moves to the sensing end of the sensor 71, it indicates that the position of the motor shaft has been adjusted to the preset position. The sensor 71 generates a corresponding signal and feeds the signal back to the controller. Based on the signal, the controller controls the servo motor 341 of the rotating mechanism 34 to stop rotating, and controls the moving mechanism 33 to drive the sleeve 31 to move up, completing the entire motor shaft position adjustment process. Through the above scheme, the position of the motor shaft can be adjusted to the preset position more accurately.

[0056] In this embodiment, the motor shaft rotation orientation device further includes three first safety gratings 51, three second safety gratings 52 and a controller, the position of each first safety grating 51 corresponds to the position of a sleeve 31 of a motor shaft rotation orientation device 30, and the position of each second safety grating 52 corresponds to the position of a carrier 32 of a motor shaft rotation orientation device 30; the first safety grating 51, the second safety grating 52, the moving mechanism 33 and the rotating mechanism 34 are all electrically connected to the controller. In an application scenario, when an operator replaces the motor on the carrier 32 or puts his hand between the sleeve 31 and the carrier 32 for other reasons, the first safety grating 51 and the second safety grating 52 sense an object signal and feed the signal back to the controller, and the controller controls the rotating mechanism 34 and the moving mechanism 33 to stop working based on the signal, thereby preventing the operator from being injured by the equipment and improving the safety performance of the equipment.

A person skilled in the art may change, modify, substitute and modify the above embodiments within the scope of the invention without departing from the principles and purpose of the present invention. All such changes should fall within the scope of protection of the claims of the present invention.
