Description

Technical Field

[0001] This invention relates to the field of motor winding technology, and in particular to a wire sheathing mechanism and an automatic sheathing device. Background Technology

[0002] The automotive drive motor is the most critical component. Its main function is to generate driving torque, and it is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor stator includes the stator core, which is typically wound using a winding machine to form windings. After winding, insulating tubes need to be fitted onto the ends of the conductors for insulation. To facilitate the fitting of the insulating tubes, the ends of the conductors need to extend along the axial direction of the motor.

[0003] In actual production, the operation of installing insulating tubes on the ends of conductors is done manually. Operators need to align the conductors with the insulating tubes before they can install the insulating tubes on the ends of the conductors. This is labor-intensive, has low production efficiency, and is costly.

[0004] To address the aforementioned issues, it is necessary to develop a wire sheathing mechanism and an automatic sheathing device to solve the problems of low production efficiency and high cost caused by manual sheathing of insulating tubes. Summary of the Invention

[0005] The purpose of this invention is to provide a wire sleeve mechanism and an automatic sleeve device, which improves the efficiency of sleeved wires with insulating tubes, reduces the workload of operators, and lowers costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A wire sheathing mechanism includes a base, on which a plurality of sheathing assemblies are spaced apart circumferentially. Each sheathing assembly includes two clamping parts and an opening structure. When the two clamping parts are engaged, they form a sheathing channel. The sheathing channel includes a large-diameter section and a small-diameter section that are connected. The end of the wire passes through the small-diameter section. An insulating tube is disposed in the large-diameter section. When the insulating tube moves toward the small-diameter section and is sheathed on the wire, the opening structure drives the two clamping parts to separate.

[0008] In some embodiments, a transition section is provided between the large-diameter section and the small-diameter section, the inner diameter of the transition section gradually decreases in the direction from the large-diameter section to the small-diameter section, and the inner wall of the transition section forms the opening structure.

[0009] In some embodiments, the sleeve assembly further includes a base with a through hole, the clamping part is rotatably connected to the base, and the through hole communicates with the sleeve channel.

[0010] In some embodiments, the sleeve assembly further includes a pin and a sleeve, the base has a pin hole, the end of the clamping part is connected to a rotating part, the pin passes through the pin hole and the rotating part, and the sleeve is fitted onto the base and covers at least part of the pin hole.

[0011] In some embodiments, the sleeve includes a base plate and a side plate surrounding the outer periphery of the base plate. The base has a connecting portion protruding from the side opposite to the clamping portion. The base is disposed within the side plate. The connecting portion passes through the base plate and is detachably connected to the base.

[0012] In some embodiments, the sleeve channel further includes a guide section connected to the end of the smaller diameter section away from the larger diameter section, the inner diameter of the guide section gradually decreasing in the direction close to the smaller diameter section.

[0013] In some embodiments, the sleeve assembly further includes an elastic ring that is sleeved outside the two clamping portions to secure the two clamping portions.

[0014] An automatic bushing device includes a bushing mechanism for the aforementioned conductor and a pushing mechanism. The pushing mechanism includes a lifting drive and a plurality of pushing rods. The plurality of pushing rods are disposed at the output end of the lifting drive and correspond one-to-one with a plurality of bushing assemblies. The pushing rods are capable of entering the bushing channel and pushing the insulating tube toward the conductor.

[0015] In some embodiments, the automatic sleeve device further includes a guide rail and a slide table, the sleeve mechanism is disposed on the slide table, and the slide table is slidably disposed on the guide rail so that the sleeve mechanism moves closer to or further away from the pushing mechanism.

[0016] In some embodiments, the base is rotatably connected to the slide.

[0017] The beneficial effects of this invention are:

[0018] This invention provides a wire sleeve mechanism and an automatic sleeve device. The sleeve mechanism includes a base and multiple sleeve assemblies. The base can fix the multiple sleeve assemblies so that their positions are aligned with the ends of the winding wires. Within the sleeve assembly's sleeve channel, the larger diameter section is used to place the insulating tube, and the smaller diameter section is used to fix the end of the wire. This ensures that the axis of the insulating tube coincides with the axis of the wire. Simply pushing the insulating tube towards the smaller diameter section ensures that the insulating tube is sleeved on the end of the wire. Furthermore, the opening structure allows the two clamping parts to separate, preventing the insulating tube from being unable to enter the smaller diameter section and facilitating the removal of the wire with the insulating tube sleeved.

[0019] This sleeve mechanism enables the insulation tube to be aligned with the conductor, thereby improving the efficiency of sleeve installation on the conductor, reducing the workload of operators, and lowering costs. Attached Figure Description

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The automotive drive motor is the most critical component. Its main function is to generate driving torque, and it is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor stator includes the stator core, which is typically wound using a winding machine to form windings. After winding, insulating tubes need to be fitted onto the ends of the conductors for insulation. To facilitate the fitting of the insulating tubes, the ends of the conductors need to extend along the axial direction of the motor.

[0036] To improve the efficiency of installing insulating tubes, this embodiment provides an automatic tube-inserting device, such as... Figures 1-3As shown, the automatic bushing device includes a fixed frame 7 and a fixing assembly (not shown in the figure). The fixing assembly is configured to fix the stator of the motor and can be raised and lowered relative to the fixed frame 7. The fixed frame 7 is also provided with a bushing mechanism 1 for the conductor and a pushing mechanism 2. The bushing mechanism 1 includes a base 11, on which multiple bushing assemblies 12 are arranged circumferentially. The base 11 can fix multiple bushing assemblies 12 so that the positions of multiple bushing assemblies 12 are aligned with the ends of the conductors 100 of the winding. The bushing assembly 12 has a bushing channel 122, and the ends of the insulating tube 101 and the conductor 100 are both disposed in the bushing channel 122. The pushing mechanism 2 includes a lifting drive 21 and multiple pushing rods 22. The multiple pushing rods 22 are disposed at the output end of the lifting drive 21. Each of the multiple pushing rods 22 corresponds to a multiple bushing assembly 12. The pushing rods 22 can enter the bushing channel 122 and push the insulating tube 101 toward the conductor 100.

[0037] This embodiment uses a three-phase motor as an example. For ease of operation, the stator is axially arranged vertically, meaning that the three sets of conductors 100 in the stator winding have six ends, all extending vertically upwards. The bushing mechanism 1 is located above the fixing assembly. Multiple bushing assemblies 12 correspond one-to-one with the ends of the conductors 100. An insulating tube 101 is installed inside each bushing assembly 12. When the fixing assembly rises, the ends of the conductors 100 are inserted into the corresponding bushing assembly 12's fitting channel 122. The pushing mechanism 2 is located above the bushing assembly 12. When the lifting drive 21 drives multiple pushing rods 22 to descend, the pushing rods 22 enter the corresponding bushing assembly 12's fitting channel 122 and push the insulating tube 101 to fit onto the end of the conductor 100.

[0038] Preferably, the automatic sleeve device further includes a guide rail 3 and a slide table 4. The sleeve mechanism 1 is mounted on the slide table 4, which is slidably mounted on the guide rail 3 to allow the sleeve mechanism 1 to move closer to or further away from the pushing mechanism 2. The slide table 4 can move on the guide rail 3 to give the sleeve mechanism 1 a sleeve position and a loading position. When the slide table 4 is away from the pushing mechanism 2, it is in the loading position, where the operator can insert the insulating tube 101 into the sleeve channel 122 of the sleeve assembly 12. Then, when the slide table 4 moves along the guide rail 3 to below the pushing mechanism 2, it is in the sleeve position. At this time, the fixing component rises to insert the end of the wire 100 into the corresponding sleeve channel 122. Then, the lifting drive component 21 drives multiple pushing rods 22 to descend. The pushing rods 22 enter the corresponding sleeve channel 122 of the sleeve assembly 12 and push the insulating tube 101 to be sleeved onto the end of the wire 100. The lifting drive component 21 can be a cylinder, a linear motor 5, or a lead screw and nut structure, all of which are existing technologies and will not be described in detail here.

[0039] In this embodiment, the automatic sleeve device also includes a linear motor 5, which is mounted on the fixed frame 7. The output end of the linear motor 5 is fixedly connected to the slide table 4, and the linear motor 5 can drive the slide table 4 to move.

[0040] In this embodiment, the base 11 is rotatably connected to the slide table 4. When the slide table 4 moves to the loading position, the base 11 can rotate to change the position of the sleeve assembly 12, moving the sleeve assembly 12 in front of the operator so that the operator can easily place the insulating tube 101 into the sleeve assembly 12. When the slide table 4 moves to the sleeve position, the base 11 can rotate to align the sleeve assembly 12 with the end of the corresponding wire 100 and the push rod 22, ensuring that the end of the wire 100 and the push rod 22 can be inserted into the corresponding sleeve channel 122.

[0041] Furthermore, the automatic sleeve-making device also includes a drive motor 6, a driving wheel, a driven wheel, and a transmission belt. The drive motor 6 is mounted on the slide table 4, and its output shaft is fixedly connected to the driving wheel. The base 11 is fixedly connected to the driven wheel. The transmission belt is fitted onto the driving wheel and the driven wheel and is tensioned by both wheels. The drive motor 6 can drive the rotation of the base 11, improving the automation level of the automatic sleeve-making device. Specifically, the drive motor 6 is a servo motor, allowing the operator to precisely control the rotation angle of the base 11.

[0042] Specifically, both the driving and driven pulleys are synchronous pulleys, and the transmission belt is a synchronous belt. The synchronous pulleys and the synchronous belt are meshed by teeth, so there will be no relative slippage, which improves the control accuracy.

[0043] Understandably, if the spool of the insulating tube 101 and the conductor 100 do not align, the conductor 100 cannot be inserted into the insulating tube 101. Figures 2-4 As shown, to solve the above problems, in this embodiment, the sleeve assembly 12 includes two clamping parts 121 and an opening structure. When the two clamping parts 121 are engaged, they form a sleeve channel 122. The sleeve channel 122 includes a large-diameter section 1221 and a small-diameter section 1222 that are connected. The end of the conductor 100 passes through the small-diameter section 1222. An insulating tube 101 is provided in the large-diameter section 1221. When the insulating tube 101 moves toward the small-diameter section 1222 and is sleeved on the conductor 100, the opening structure drives the two clamping parts 121 to separate.

[0044] Within the sleeve assembly 122, the large-diameter section 1221 is used to place the insulating tube 101, and the small-diameter section 1222 is used to fix the end of the conductor 100. Therefore, it can be ensured that the axis of the insulating tube 101 and the conductor 100 coincides. It is only necessary to push the insulating tube 101 to move it toward the small-diameter section 1222 to ensure that the insulating tube 101 is sleeved on the end of the conductor 100. In addition, the opening structure can also separate the two clamping parts 121 to prevent the insulating tube 101 from being unable to enter the small-diameter section 1222, and facilitate the removal of the conductor 100 with the insulating tube 101 sleeved on it.

[0045] The sleeve mechanism 1 enables the insulating tube 101 to be aligned with the conductor 100, thereby improving the efficiency of sleeved insulating tube 101 on conductor 100, reducing the workload of operators, and reducing costs.

[0046] It is worth noting that the inner diameter of the large diameter section 1221 is equal to or greater than the outer diameter of the insulating tube 101, and the inner diameter of the small diameter section 1222 is equal to or greater than the outer diameter of the conductor 100. The inner diameter of the small diameter section 1222 is smaller than the outer diameter of the insulating tube 101. When the insulating tube 101 is located within the large diameter section 1221, the tube hole of the insulating tube 101 is directly facing the conductor 100 to ensure that the conductor 100 can be smoothly inserted into the insulating tube 101 when the insulating tube 101 is pushed towards the conductor 100.

[0047] like Figure 3 and Figure 4 As shown, a transition section 1223 is provided between the large-diameter section 1221 and the small-diameter section 1222. The inner diameter of the transition section 1223 gradually decreases from the large-diameter section 1221 towards the small-diameter section 1222, and the inner wall of the transition section 1223 forms an open structure. When the insulating tube 101 moves toward the conductor 100, the insulating tube 101 will push open the two clamping parts 121 through the transition section 1223, thereby allowing the insulating tube 101 to enter the small-diameter section 1222 and be sleeved on the conductor 100.

[0048] Understandably, during the process of the insulating tube 101 opening the two clamping parts 121, the small-diameter section 1222 cannot continue to fix the conductor 100, which may cause the conductor 100 to shift, making it impossible for the insulating tube 101 to be fitted onto the conductor 100. To solve this problem, the end of the conductor 100 needs to be within the transition section 1223 before moving the insulating tube 101. When the insulating tube 101 enters the transition section 1223, the two clamping parts 121 have just been opened, and the small-diameter section 1222 can still fix the conductor 100 to a certain extent, preventing the conductor 100 from shifting too much and ensuring that the insulating tube 101 can be fitted onto the conductor 100.

[0049] In other embodiments, the opening structure can also be a finger cylinder, with two grippers of the finger cylinder connected to a clamping part 121. The opening distance of the two grippers is controlled by the pushing distance of the pushing mechanism 2 on the insulating tube 101, which can also ensure that the insulating tube 101 can enter the position of the small diameter section 1222 and be sleeved on the wire 100.

[0050] In this embodiment, the sleeve assembly 12 further includes a base 123, which has a through hole. The clamping part 121 is rotatably connected to the base 123, and the through hole communicates with the sleeve channel 122. The base 123 can connect the two clamping parts 121, making the sleeve assembly 12 a single unit, and the base 123 can also improve the stability of the two clamping parts 121 when rotating.

[0051] Specifically, the sleeve assembly 12 also includes a pin 124 and a sleeve 125. The base 123 has a pin hole, and the end of the clamping part 121 is connected to a rotating part 126. The pin 124 passes through the pin hole and the rotating part 126, and the sleeve 125 is fitted onto the base 123 and covers at least part of the pin hole. Using the pin 124 to connect the base 123 and the clamping part 121 can ensure the rotatable connection between the clamping part 121 and the base 123, and also facilitate disassembly and installation. The sleeve 125 can cover the pin hole to prevent the pin 124 from disengaging from the pin hole during use.

[0052] Furthermore, the sleeve 125 includes a base plate 1251 and a side plate 1252 surrounding the outer periphery of the base plate 1251. The base 123 has a connecting part 1231 protruding from the side opposite to the clamping part 121. The base 123 is disposed within the side plate 1252. The connecting part 1231 passes through the base plate 1251 and is detachably connected to the base 11. The connecting part 1231 can be connected to the base 11, thereby fixing the base plate 1251 against the base 11. At this time, the sleeve 125, the base 11, and the base 123 are all fixed. Disassembly only requires disconnecting the connecting part 1231 from the base 11.

[0053] In this embodiment, the connecting part 1231 is threadedly connected to the base 11, and the push rod 22 can pass through the base 11 and enter the sleeve channel 122 through the connecting part 1231.

[0054] Preferably, the sleeve assembly 12 further includes an elastic ring (not shown in the figure), which is sleeved over the two clamping portions 121 to fix the two clamping portions 121. The elastic ring can clamp the two clamping portions 121. The insulating tube 101 separates the two clamping portions 121 by rotating them in opposite directions through the transition section 1223. After the wire 100 and the insulating tube 101 are removed, the elastic ring can reset the two clamping portions 121 and ensure the stability of the two clamping portions 121, thereby improving efficiency.

[0055] Understandably, during the upward movement of the stator driven by the fixed component, the conductor 100 may deviate from the small-diameter section 1222 of the sleeve channel 122 and fail to enter the small-diameter section 1222. To solve this problem, the sleeve channel 122 also includes a guide section 1224, which is connected to the end of the small-diameter section 1222 away from the large-diameter section 1221. The inner diameter of the guide section 1224 gradually decreases in the direction close to the small-diameter section 1222.

[0056] The guide section 1224 has a large opening, which ensures that the end of the conductor 100 can enter the guide section 1224 and slide along the inclined inner wall of the guide section 1224 to the small diameter section 1222, and finally enter the small diameter section 1222.

[0057] The working process of this automatic sleeve device is described below:

[0058] First, the slide table 4 is moved to the loading position. The operator drives the base 11 to rotate via the drive motor 6, so that the insulating tubes 101 are inserted into the large-diameter sections 1221 of the corresponding sleeve channels 122 in sequence. The stator is fixed to the fixing assembly. Then, the slide table 4 is moved along the guide rail 3 to the sleeve position via the linear motor 5, and the base 11 is rotated via the drive motor 6, so that the sleeve assembly 12 corresponds one-to-one with the stator wires 100 and the push rods 22 of the push mechanism 2. The push rods 22 are driven to descend via the lifting drive component 21, and the push rods 22 enter the corresponding... The large-diameter section 1221 of the sleeve channel 122 is pushed and the insulating tube 101 is moved toward the conductor 100; the insulating tube 101 separates the two clamping parts 121 through the inner wall of the transition section 1223, and the insulating tube 101 is sleeved on the conductor 100; the push rod 22 continues to descend, and at the same time the fixing component drives the stator to move downward until the conductor 100 and the insulating tube 101 are both disengaged from the sleeve channel 122; the lifting drive 21 drives the push rod 22 to rise and disengage from the sleeve channel 122, and the linear motor 5 drives the slide table 4 to move back to the loading position.

[0059] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
