Description
Automatic oiling device suitable for batch production of rotors Technical Field
[0001] This utility model relates to the field of motor processing technology, and in particular to an automatic oiling device suitable for batch production of rotors. Background Technology
[0002] The rotor, the core component of an electric motor, plays a crucial role in the long-term use of the motor. Therefore, during the motor manufacturing process, a layer of anti-rust oil is applied to the outer surface of the rotor to prevent rust from forming on the rotor surface during long-term use and affecting the normal operation of the motor.
[0003] In existing technologies, the application of rust-preventive oil to the outer surface of rotors is partially done manually, which is inefficient and results in uneven oil application. To avoid the problems associated with manual oiling, CN219643765U discloses a rotor oiling device that improves the efficiency and uniformity of rotor oiling through the coordinated operation of a lateral movement mechanism, a clamping mechanism, a rotating mechanism, and an oiling mechanism. Specifically, during oiling, the oiling mechanism first extends the oiling point push rod, pushing the oiling connecting seat to move so that the oiling plate contacts the outer ring of the rotor. Then, the oiling pump is started, and rust-preventive oil is introduced into the oiling connecting seat through the oil pipe. The rust-preventive oil in the oiling connecting seat passes through the oil hole into the oiling plate, which then evenly applies the absorbed rust-preventive oil to the outer surface of the rotor, completing the oiling operation. During the oiling process, dripping rust-preventive oil falls into the oiling box. When a certain amount of rust-preventive oil has been collected in the oiling box, a recovery pump is started to redirect the rust-preventive oil back into the oiling tank. Although this mechanism can meet the requirements for automatic oiling of rotors, its oiling mechanism has a complex overall structure and is cumbersome to use.
[0004] Therefore, for the aforementioned device that can automatically oil the rotor, its structure still needs to be further optimized from the perspective of simplifying the oiling process. Summary of the Invention
[0005] The purpose of this invention is to provide an automatic oiling device suitable for batch production of rotors, so as to solve the technical problem of simplifying the oiling operation process.
[0006] The automatic oiling device for batch rotors of this invention is implemented as follows:
[0007] An automatic oiling device suitable for batch production of rotors, comprising:
[0008] An oiling assembly includes an oil reservoir for storing oil and two guide rollers arranged side-by-side in the oil reservoir and partially submerged in the oil. The rotor to be oiled is adapted to be placed on the gap formed by the two guide rollers so as to be tangent to both guide rollers simultaneously. One of the guide rollers is a driving roller connected to a drive member for driving its rotation, and the other guide roller is a driven roller adapted to be passively rotated along with the driving roller and the rotor to be oiled.
[0009] The feeding assembly includes at least a feeding tray located on one side of the oiling assembly;
[0010] The feeding assembly includes at least a feeding tray located on the other side of the oiling assembly;
[0011] A clamping assembly, which includes at least a gripper for gripping a rotor.
[0012] In optional embodiments of this invention, the radial dimensions of the driving roller and the driven roller may be the same or different; and
[0013] The depth to which the driving roller and the driven roller are immersed in the oil is no greater than the radius of the driving roller and the driven roller, respectively.
[0014] In an optional embodiment of this invention, the driving roller and / or driven roller has a hollow, axially extending cavity, and a plurality of oil outlet holes communicating with the cavity are evenly distributed on the outer wall surface of the driving roller and / or driven roller; and
[0015] The driving roller and / or driven roller are partially immersed in oil to allow the oil to seep into the cavity through the partial oil outlet.
[0016] In an optional embodiment of this invention, the feeding assembly further includes a feeding guide structure for rolling cooperation with the feeding tray;
[0017] The feeding assembly also includes a feeding guide structure for rolling cooperation with the feeding tray.
[0018] In an optional embodiment of this utility model, both the feeding guide structure and the unloading guide structure include a pair of symmetrically distributed roller guide groups and a sliding seat for rolling cooperation with the pair of roller guide groups;
[0019] Each of the roller guide assemblies includes a plurality of rollers arranged in a straight line;
[0020] The sliding seat is provided with a loading area for supporting the loading or unloading pallet.
[0021] In an optional embodiment of this utility model, the feeding assembly and the unloading assembly further include positioning structures that cooperate with the sliding seat body;
[0022] The positioning structure includes a positioning hole on the bottom surface of the sliding seat facing away from the loading area, a positioning post suitable for partial insertion into the positioning hole, and a linear motion drive connected to the positioning post for driving the positioning post to move up and down.
[0023] In an optional embodiment of this invention, the width of the gap formed between the driving roller and the driven roller is smaller than the outer diameter of the rotor to be oiled.
[0024] In an optional embodiment of this invention, the driving roller and / or driven roller are made of nylon.
[0025] In an optional embodiment of this utility model, the loading tray and unloading tray each include a support plate and a limiting groove on the support plate, which is suitable for embedding a pair of rotors to be oiled.
[0026] In an optional embodiment of this invention, the clamping assembly further includes a three-axis moving structure for driving the jaws to move.
[0027] By adopting the above technical solution, this utility model has the following beneficial effects: The automatic oiling device for batch rotors of this utility model achieves automated oiling operation for batch rotors through the cooperation of the oiling component, the feeding component, the unloading component, and the clamping component, thereby improving the efficiency of oiling operation for batch rotors. Furthermore, in the oiling process, by placing the rotor to be oiled in the gap formed by two oil guide rollers, the rotation of the drive roller drives the rotor and the driven roller to rotate, thus coating the oil adhering to the outer surfaces of the drive and driven rollers onto the outer surface of the rotor. The synchronous rotation of the drive and driven rollers improves the uniformity of the oil applied to the rotor's outer surface. Therefore, for the overall oiling assembly, only the rotation of the drive roller needs to be achieved through a driving component to complete the oiling operation on the rotor's outer surface. The overall oiling process is simple, easy to operate, and has a low failure rate. Attached Figure Description

Detailed Implementation
[0035] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0036] Example 1:
[0037] Please refer to Figures 1 to 4. This embodiment provides an automatic oiling device suitable for batch production of rotors, including: an oiling assembly, a feeding assembly, a discharging assembly, and a clamping assembly used in conjunction. The feeding assembly and the discharging assembly are respectively located on two different sides of the oiling assembly, which can be selected as opposite sides to facilitate manual feeding and discharging. The clamping assembly is used to clamp the rotors to be oiled from the feeding assembly and transfer them to the oiling assembly. After the rotors have completed the oiling operation, they are clamped from the oiling assembly and transferred to the discharging assembly.
[0038] Based on the above, specifically, the clamping assembly also includes a three-axis moving structure 12 for driving the gripper 11. The gripper 11 and the three-axis moving structure 12 can be selected from any mature means in the prior art, and this embodiment does not absolutely limit their specific structure and implementation principle.
[0039] Secondly, the overall structure and implementation principle of the feeding and unloading components are the same. The feeding component includes at least a feeding tray 21 located on one side of the oiling component; the unloading component includes at least a unloading tray 22 located on the other side of the oiling component. The feeding component also includes a feeding guide structure for rolling engagement with the feeding tray 21; the unloading component also includes a unloading guide structure for rolling engagement with the unloading tray 22. The feeding tray 21 and the unloading tray 22 each include a support plate and a limiting groove 23 arranged in an array on the support plate, suitable for partially embedding a pair of rotors to be oiled.
[0040] Furthermore, the feeding and unloading guiding structures used in this embodiment are the same. Therefore, this embodiment, in conjunction with the accompanying drawings, illustrates one scenario where both include a pair of symmetrically distributed roller guide groups and a sliding seat 24 for rolling engagement with the pair of roller guide groups; each roller guide group includes multiple rollers 25 arranged in a straight line. Based on this, it should be noted that the sliding seats 24 included in the feeding and unloading guiding structures move in opposite directions relative to the oiling assembly during actual use. In this structure, when the sliding seat 24 is manually pushed or pulled, the sliding seat 24 engages with the roller guide groups in a rolling engagement.
[0041] Based on the above, it should be noted that the sliding seat 24 is provided with a loading area for supporting the loading pallet 21 or the unloading pallet 22. This allows the loading pallet 21 and the unloading pallet 22 to be picked up and placed as a single unit, improving operational efficiency.
[0042] Furthermore, it should be noted that, in order to prevent the loading tray 21 and unloading tray 22 from shaking or moving during the process of the clamping assembly removing the rotor to be oiled from the loading assembly and the oiled rotor from the unloading assembly, the loading assembly and unloading assembly in this embodiment also include positioning structures that cooperate with the sliding seat 24; the positioning structures configured for the loading assembly and the unloading assembly are the same here, therefore, this embodiment will illustrate one case with reference to the accompanying drawings:
[0043] The positioning structure includes a positioning hole 26 on the bottom surface of the sliding seat facing away from the loading area, a positioning pin 27 adapted to be partially inserted into the positioning hole 26, and a linear motion drive 28 connected to the positioning pin 27 for driving the positioning pin 27 to move up and down. The linear motion drive 28 may be, for example, but is not limited to, a cylinder. When both the loading pallet 21 and the unloading pallet 22 move to a position adjacent to the oiling assembly (this position is defined by the cooperation between the roller guide assembly and the sliding seat, that is, the roller guide assembly is designed with a maximum position stop when the sliding seat moves towards the oiling assembly), the linear motion drive 28 drives the positioning pin 27 to move towards the sliding seat so that it is partially inserted into the positioning hole 26, thereby positioning the sliding seat. When it is necessary to move the sliding seat, the positioning pin 27 is moved away from the positioning hole 26 by the action of the linear motion drive 28.
[0044] The oiling assembly will be described in detail next. It includes an oil reservoir 4 for storing oil and two guide rollers arranged side by side in the oil reservoir 4 and partially submerged in the oil. The end face of the oil reservoir 4 facing the gripper 11 has an open opening 41 suitable for the rotor to be oiled to enter and exit; the open opening 41 is equipped with a cover 3. When the rotor does not need to be oiled, simply covering it with the cover 3 can prevent dust and other impurities from entering the oil reservoir 4. When the rotor needs to be oiled, simply removing the cover 3 is sufficient.
[0045] Based on the above structure, it should be explained in detail that one of the oil guide rollers is a driving roller 5, which is connected to a driving component for rotating it. The other oil guide roller is a driven roller 8, which is adapted to passively rotate with the driving roller 5 and the rotor to be oiled. The driving component here can be a micro motor 6. The width of the gap 7 formed between the driving roller 5 and the driven roller 8 is smaller than the outer diameter of the rotor to be oiled. The rotor to be oiled is suitable for being placed on the gap 7 formed by the two oil guide rollers so that it is tangent to both oil guide rollers at the same time. In an optional implementation, the driving roller 5 and / or the driven roller 8 are made of nylon material to avoid direct contact between the metal material and the rotor during the contact process, which could damage the rotor surface.
[0046] In detail with reference to the accompanying drawings, the cooperation between the drive roller 5, the micro motor 6, and the oil storage tank 4 in this embodiment is as follows: The output shaft 61 of the micro motor 6 extends from the outside of the oil storage tank 4 through the rear part of the side wall of the oil storage tank 4 and into the oil storage tank 4, and is connected to one end of the shaft of the drive roller 5. The output shaft 61 of the micro motor 6 can be fixed to the drive roller 5 by a screw 51. The screw 51 is inserted into the drive roller 5 from a dimension perpendicular to the axial direction of the drive roller 5 to achieve mating with the output shaft 61 that is also inserted into the drive roller 5. Here, the output shaft 61 and the side wall of the oil storage tank 4 are provided with, for example, but not limited to, a bearing, or a clearance fit can be directly formed. For the other shaft end of the drive roller 5, it is connected to a fixing pin 9 via a bearing 10. A guide fixing groove 42, perpendicular to the axial direction of the drive roller 5 and extending to the open opening 41, is provided on the inner wall of the oil storage tank 4. The fixing pin 9 connected to the drive roller 5 is inserted into the guide fixing groove 42 from the open opening 41. When it is pressed to the bottom of the guide fixing groove 42, it can be fixed in the guide fixing groove 42 by screws. In this way, the entire drive roller 5 is reliably assembled in the oil storage tank 4. For the driven roller 8 in this embodiment, each of its two shaft ends is connected to a fixing pin 9 via a bearing 10. The fixing pins 9 are the same as those in the oil storage tank 4; that is, a pair of fixing pins 9 guide the driven roller 8 into the oil storage tank 4 along the guide fixing groove 42.
[0047] Based on the above, it is also necessary to explain that, theoretically, whether the radial dimensions of the driving roller 5 and the driven roller 8 are the same or different, it meets the usage requirements of this embodiment. Regardless of whether their outer diameters are the same, as long as they are tangent to the rotor to be oiled at the same time, and both the driving roller 5 and the driven roller 8 have a portion of their outer surface immersed in the oil so that the outer surfaces of the driving roller 5 and the driven roller 8 are adhered to the oil, it is sufficient. Based on this, theoretically, the end faces of the driving roller 5 and the driven roller 8 facing the inner wall of the bottom of the oil storage tank 4 can be flush or not, which can also meet the usage requirements of this embodiment. In this embodiment, with reference to the accompanying drawings, an example is given where the outer diameters of the driving roller 5 and the driven roller 8 are the same, and their end faces facing the inner wall of the bottom of the oil storage tank 4 are flush.
[0048] Based on the above, it should be noted that, in order to meet the requirements for oiling the rotor and reduce the rotational resistance of the drive roller 5 and the driven roller 8, the depth to which the drive roller 5 and the driven roller 8 are immersed in the oil in this embodiment is no greater than the radius of the drive roller 5 and the driven roller 8. It should be noted that, considering that one end of the active roller 5 in this embodiment is connected to the output shaft 61 of the micro motor 6, the output shaft 61 penetrates the side wall of the oil storage tank 4. The oil storage tank 4 contains oil. To simplify the structure and prevent the oil from overflowing from the part where the output shaft 61 meets the side wall of the oil storage tank 4 to the outside of the oil storage tank 4, the oil level in the oil storage tank 4 in this embodiment is not higher than the edge of the inner wall of the bottom of the oil storage tank 4 facing the mating hole 43 of the output shaft 61. Because the axis of the active roller 5 is coaxially mated with the output shaft 61, and the active roller 5 has a certain outer diameter, the oil level can still meet the requirement of a certain depth of immersion for the active roller 5 when it is lower than the edge of the inner wall of the bottom of the oil storage tank 4 facing the mating hole 43.
[0049] In summary, this embodiment achieves automated oiling of batch rotors through the cooperation of the oiling assembly, feeding assembly, unloading assembly, and clamping assembly, thereby improving the efficiency of oiling operations for batch rotors. Furthermore, in the oiling process, by placing the rotor to be oiled on the gap 7 formed by the two oil guide rollers, the rotation of the drive roller 5 drives the rotor and the driven roller 8 to rotate, thereby coating the oil adhering to the outer surfaces of the drive roller 5 and the driven roller 8 onto the outer surface of the rotor. Moreover, the synchronous rotation of the drive roller 5 and the driven roller 8 can improve the uniformity of the oil applied to the outer surface of the rotor. Therefore, for the overall oiling assembly, the oiling operation on the outer surface of the rotor can be completed simply by driving the active roller 5 to rotate. The operator only needs to load the rotor to be oiled into the loading tray 21 and then place the loading tray 21 into the sliding seat 24 of the loading assembly. After completing the oiling operation on the rotor in the loading tray 21, the operator only needs to remove the unloading tray 22 from the sliding seat 24 of the unloading assembly. The overall oiling process is simple, easy to operate, and has a low failure rate.
[0050] Example 2:
[0051] Please refer to Figures 1 to 6. Based on the automatic oiling device for batch rotors in Embodiment 1, the automatic oiling device for batch rotors provided in this embodiment has a hollow, axially extending cavity 81 for the driving roller 5 and / or driven roller 8, and a plurality of oil outlet holes 82 communicating with the cavity 81 are evenly distributed on the outer wall surface of the driving roller 5 and / or driven roller 8. This embodiment is described with reference to the accompanying drawings, taking the case where the cavity 81 is provided only inside the driven roller 8 and the oil outlet holes 82 are provided on the outer wall surface of the driven roller 8 as an example.
[0052] Based on the above structure, it should be noted that in this embodiment, the driven roller 8 is partially immersed in oil so that the oil can seep into the cavity 81 through the oil outlet 82. With this configuration, when the driven roller 8 contacts the outer surface of the rotor, not only can the oil adhering to its outer surface coat the rotor's outer surface, but the oil stored in the cavity 81 can also flow onto the rotor's outer surface through the oil outlet 82, thus improving the efficiency of the rotor oiling operation.
