Description

Technical Field

[0001] The present application relates to the technical field of brushless motors, and in particular to a glue potting tool for a brushless motor stator and a glue potting process thereof. Background Art

[0002] The stator of a brushless motor requires glue filling during the production and assembly process. The traditional glue filling method is to gravity fill the motor stator from the top of the end cover. However, this glue filling method cannot ensure the alignment of the stator housing and its internal stator winding, resulting in inconsistent product quality after glue filling.

[0003] To address the problem of being unable to ensure the neutrality between the stator housing and its internal stator winding, invention patent CN115102348A discloses a servo motor stator glue filling tool and glue filling method, including a glue filling module. The glue filling module has a positioning groove for adapting to the stator housing, a positioning hole is vertically opened in the middle of the positioning groove, a limiting ring 1 is concentrically provided on the edge of the positioning hole, and a vertical positioning rod is provided in the positioning hole to transition with the stator winding. The positioning rod has a glue pressing plate on the top, and a limiting ring 2 is provided on the bottom surface of the glue pressing plate, which is opposite to the limiting ring 1. The inner diameters of the limiting rings 1 and 2 are the same and both are larger than the inner diameter of the stator winding. A positioning member for alignment is provided in the glue filling tool to ensure the neutrality between the stator housing and its internal stator winding during the glue filling process.

[0004] However, since the inner diameters of the stator windings of brushless motors of different specifications are different, when the inner diameter of the stator winding is larger than the outer diameter of the positioning rod, the positioning rod cannot center the stator winding, resulting in a low applicability and large limitations of the glue filling tooling. Summary of the Invention

[0005] In order to meet the needs of centering stators of different specifications and improve the applicability of glue potting tooling, the present application provides a glue potting tooling for a brushless motor stator and a glue potting process thereof.

[0006] In a first aspect, the present application provides a glue-filling tool for a brushless motor stator, which adopts the following technical solution:

[0007] A glue potting tool for a brushless motor stator includes a tool frame, a processing table for placing a casing is provided in the tool frame, a stator winding is provided in the casing, a positioning cylinder is provided on the top surface of the processing table, the positioning cylinder is respectively plugged into the casing and the stator winding, a plurality of extrusion rods are slidingly provided through the side wall of the positioning cylinder, the positioning cylinder is provided with a moving mechanism for simultaneously driving the plurality of extrusion rods to move, and the processing table is provided with a positioning assembly for positioning and clamping the casing.

[0008] By adopting the above technical solution, when the stator winding needs to be glued, the casing is first placed on the processing table, and then the casing is positioned and clamped with the positioning cylinder as the center through the positioning assembly, and then the stator winding is placed in the casing, and then the moving mechanism is used to simultaneously drive multiple extrusion rods to move. At this time, multiple extrusion rods simultaneously squeeze the inner wall of the stator winding, prompting the stator winding to be centered and limited in the casing. The moving mechanism simultaneously drives multiple extrusion rods to move, thereby meeting the centering and limiting of stator windings of different specifications, which is beneficial to improving the applicability of the glue filling tooling.

[0009] Optionally, the moving mechanism includes a rotating shaft, which is rotatably arranged in the positioning cylinder, and the side walls of the rotating shaft are respectively provided with arc grooves corresponding to the positions of the multiple extrusion rods, and one end of the multiple extrusion rods is respectively connected to the corresponding arc grooves in a limiting sliding manner, and the arc grooves are arc-shaped from shallow to deep.

[0010] By adopting the above technical solution, when the rotating shaft is driven to rotate counterclockwise, under the linear guidance of the positioning cylinder, the rotating shaft drives the extrusion rod to move outward through the shallow arc groove, and when the rotating shaft rotates in the opposite direction, the extrusion rod is driven to move inward through the deep arc groove, which is beneficial to improving the stability of the centering positioning of stator windings of different specifications.

[0011] Optionally, a rotating seat is provided on the bottom surface of the processing table, the bottom end of the rotating shaft extends into the rotating seat, a coil spring is provided in the rotating seat, one end of the coil spring is fixedly connected to the interior of the rotating seat, and the other end of the coil spring is fixedly connected to the side wall of the rotating shaft, and the processing table is provided with a limit assembly for one-way locking of the rotating shaft.

[0012] By adopting the above technical solution, when the rotating shaft rotates in the forward direction, the rotating shaft simultaneously drives multiple extrusion rods to move downward, and the coil spring is elastically deformed. When the rotating shaft is released, the limit assembly locks the rotating shaft in one direction, and the multiple extrusion rods are fixed at the current length, which is beneficial to improve the stability of the multiple extrusion rods in extruding and limiting the stator winding.

[0013] Optionally, the limiting assembly includes a wedge-shaped limiting rod, the bottom end fixed sleeve of the rotating shaft is provided with a gear, the bottom surface of the processing table is provided with a support, the wedge-shaped limiting rod slides through the support, one end of the wedge-shaped limiting rod cooperates with the gear, and the processing table is provided with an elastic part for cooperating to drive the wedge-shaped limiting rod to move.

[0014] By adopting the above technical solution, the wedge-shaped limit rod is always matched with the gear through the elastic member. When the rotating shaft rotates in the forward direction, the rotating shaft drives the gear to rotate, and the wedge-shaped limit rod moves back and forth through the elastic member. When the rotating shaft rotates in the reverse direction, the wedge-shaped limit rod clamps the gear, making it impossible for the rotating shaft to rotate in the reverse direction, which is conducive to ensuring the stability of the multiple extrusion rods in extruding and limiting the stator winding.

[0015] Optionally, the elastic member is a spring, which is sleeved on the wedge-shaped limiting rod, one end of the spring is fixedly connected to the side wall of the wedge-shaped limiting rod, and the other end of the spring is fixedly connected to the support.

[0016] By adopting the above technical solution, when the wedge-shaped limit rod moves in the direction away from the gear, the wedge-shaped limit rod squeezes the spring. When the wedge-shaped limit rod is realigned with the gear tooth root, the spring releases the elastic force and drives the wedge-shaped limit rod to re-engage with the gear, which is beneficial to improving the stability of the unidirectional rotation of the shaft.

[0017] Optionally, the positioning assembly includes multiple positioning clamps, and the multiple positioning clamps are respectively slidably set on the top surface of the processing table. The multiple positioning clamps enclose the placement space of the casing, and the processing table is respectively provided with a driving member for driving the positioning clamps to slide.

[0018] By adopting the above technical solution, when the casing needs to be positioned, the casing is first placed on the positioning cylinder, and then the positioning clamps are driven by the driving parts to move toward the casing. At this time, the casing is centered with the positioning cylinder as the axis, which is beneficial to improve the stability of the casing centered on the processing table.

[0019] Optionally, the inner walls of the plurality of positioning clamps are respectively provided with drying tubes.

[0020] By adopting the above technical solution, when the glue needs to be dried, the drying tube is started after the positioning clamp clamps the positioning cylinder. At this time, the drying tube heats the outer wall of the casing, thereby promoting the curing of the glue.

[0021] Optionally, a lifting plate is provided on the tooling frame for lifting, an upper cover is provided on the bottom of the lifting plate, an inner pressure plate is provided on the bottom of the upper cover, the tooling frame is provided with a lifting member for driving the lifting plate to lift, and a glue injection hole is provided on the top surface of the lifting plate.

[0022] By adopting the above technical solution, when it is necessary to seal the top of the casing and the stator winding, the lifting plate is driven down by the lifting member, and the lifting plate simultaneously drives the upper cover and the inner pressure plate to descend. At this time, the upper cover seals the top of the casing, and the inner pressure plate seals the top of the stator winding. Then, glue is poured into the gap between the casing and the stator winding through the glue filling hole until the glue fills the gap, which is beneficial to improve the stability of the glue filling between the casing and the stator winding.

[0023] Optionally, the inner pressure plate includes an inner ring sub-plate and an outer ring sub-plate, the inner ring sub-plate is arranged on the bottom surface of the upper cover, and the outer ring sub-plate is tightly sleeved on the outer wall of the inner ring sub-plate.

[0024] By adopting the above technical solution, the outer ring sub-plate is tightly sleeved on the outer wall of the inner ring sub-plate according to the stator windings of different specifications, so that the inner pressure plate adapts to the specifications of the stator windings, which is beneficial to improve the stability of the inner pressure plate covering the top of the stator windings.

[0025] In a second aspect, the present application provides a brushless motor stator glue potting process, comprising the following steps:

[0026] Pre-assembly: Place the housing on the processing table, clamp the housing in the center using the positioning assembly, and pre-place the stator winding in the housing;

[0027] Positioning: The moving mechanism drives multiple extrusion rods to move at the same time, and the multiple extrusion rods simultaneously press against the inner wall of the stator winding, so that the stator winding is fixed in the center of the casing;

[0028] The cover drives the upper cover to cover the top of the press casing, and the inner pressure plate covers the top of the stator winding;

[0029] Glue filling: pour glue into the annular gap between the stator winding and the inner wall of the casing through the glue filling hole;

[0030] Drying: Start the drying tube, which heats the outer wall of the casing to accelerate the curing of the glue;

[0031] Demould, open the upper cover and inner pressure plate, rotate to loosen the stator winding, loosen the clamping of the casing, take out the casing, and complete the glue filling.

[0032] By adopting the above technical solution, through the steps of pre-installation, positioning, capping, glue filling, drying and demoulding, the glue is finally filled and solidified between the stator winding and the casing, which is beneficial to improving the stability of the brushless stator glue filling.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. When the stator needs to be glued, first place the casing on the processing table, then use the positioning assembly to position and clamp the casing with the positioning cylinder as the center, then place the stator winding in the casing, and then use the moving mechanism to simultaneously drive multiple extrusion rods to move. At this time, multiple extrusion rods simultaneously squeeze the inner wall of the stator winding, prompting the stator winding to be centered and limited in the casing. By using the moving mechanism to simultaneously drive multiple extrusion rods to move, it is possible to meet the centering and limiting of stator windings of different specifications, thereby helping to expand the applicability of the glue filling tooling;

[0035] 2. Through the steps of pre-installation, positioning, capping, glue filling, drying and demoulding, the glue is finally filled and solidified between the stator winding and the casing, which is beneficial to improve the stability of the brushless stator glue filling.

[0045] The following is combined with Figure 1-8 This application is described in further detail.

[0046] First, see Figure 1-Figure 4 A glue-filling tool for a brushless motor stator includes a tool frame 1, a processing table 2 is installed in the tool frame 1, and the processing table 2 is used to place a casing 25. In this embodiment, there are two processing positions on the processing table 2 for placing the casing 25. A stator winding 3 is installed in the casing 25, and a positioning cylinder 4 is fixedly connected to the top surface of the processing table 2, and the positioning cylinder 4 is respectively inserted into the casing 25 and the stator winding 3. An extrusion rod 5 slides through the side wall of the positioning cylinder 4, and the number of the extrusion rods 5 is set to be multiple. The positioning cylinder 4 is equipped with a moving mechanism, and the moving mechanism is used to simultaneously drive multiple extrusion rods 5 to move toward or away from the stator winding 3. The processing table 2 is equipped with a positioning component, and the positioning component is used to position and clamp the casing 25.

[0047] When the stator winding 3 needs to be glued, the housing 25 is first placed on the positioning cylinder 4 and placed on the surface of the processing table 2. The housing 25 is then positioned and clamped using the positioning assembly. At this time, the housing 25 is positioned and clamped with the positioning cylinder 4 as the axis. After the housing 25 is positioned and clamped, the stator winding 3 is inserted and placed in the positioning cylinder 4. The moving mechanism then simultaneously drives the multiple extrusion rods 5 to move toward the stator winding 3. At this time, the multiple extrusion rods 5 simultaneously squeeze and press against the inner wall of the stator winding 3, and the stator winding 3 is centered and limited in the housing 25, completing the centering of the stator winding 3 of the current specification in the housing 25.

[0048] For details, see Figure 4 and Figure 5 The moving mechanism includes a rotating shaft 6, which is rotatably mounted in the positioning cylinder 4. The sidewall of the rotating shaft 6 is provided with arc grooves 7 corresponding to the positions of the multiple extrusion rods 5. The arc grooves 7 are arranged from shallow to deep and are in an arc shape. One end of the extrusion rod 5 is connected to the arc groove 7 in a limited sliding manner.

[0049] When the shaft 6 rotates counterclockwise, guided by the positioning cylinder 4, the shaft 6 drives the extrusion rod 5 through the shallow section of the arc slot 7 to move horizontally toward the stator winding 3. At this time, the extrusion rod 5 presses and presses against the inner wall of the stator winding 3. When the shaft 6 rotates clockwise, also guided by the positioning cylinder 4, the shaft 6 drives the extrusion rod 5 through the deep section of the arc slot 7 to move horizontally away from the stator winding 3. At this time, the extrusion rod 5 detaches from the inner wall of the stator winding 3, facilitating demolding of the stator winding 3.

[0050] See also Figure 3 and Figure 4To facilitate the rotation of the rotating shaft 6, a rotating seat 8 is fixedly connected to the bottom surface of the processing table 2. The bottom end of the rotating shaft 6 passes through and extends into the rotating seat 8. A coil spring 9 is installed in the rotating seat 8. One end of the coil spring 9 is fixedly connected to the inside of the rotating seat 8, and the other end of the coil spring 9 is fixedly connected to the side wall of the rotating shaft 6.

[0051] In addition, see Figure 3 and Figure 6 The processing table 2 is also equipped with a limit assembly for one-way locking of the rotating shaft 6. The limit assembly includes a wedge-shaped limit rod 10. A gear 11 is fixedly mounted on the bottom end of the rotating shaft 6. A support 12 is fixedly connected to the bottom surface of the processing table 2. The wedge-shaped limit rod 10 is slidably mounted within the support 12. The end of the wedge-shaped limit rod 10 facing the rotating shaft 6 engages with the tooth root of the gear 11. The processing table 2 is also equipped with an elastic member for driving the wedge-shaped limit rod 10 to move horizontally.

[0052] Among them, the elastic member is a spring 13, which is sleeved on the wedge-shaped limiting rod 10, and one end of the spring 13 is fixedly connected to the side wall of the wedge-shaped limiting rod 10, and the other end of the spring 13 is fixedly connected to one end of the support 12.

[0053] When the rotating shaft 6 rotates counterclockwise, it drives the extrusion rod 5 toward the inner wall of the stator winding 3 through the shallow section of the arc slot 7. At this time, the coil spring 9 elastically deforms, and under the action of the spring 13, the wedge-shaped limit rod 10 always engages with the tooth root of the gear 11. When the rotating shaft 6 stops rotating, the wedge-shaped limit rod 10 is unidirectional, and with the action of the spring 13, the rotating shaft 6 is kept stationary through the gear 11, thereby ensuring that the extrusion rod 5 always presses against the inner wall of the stator sleeve.

[0054] When the wedge-shaped limit rod 10 is pulled in the direction away from the rotating shaft 6, the wedge-shaped limit rod 10 squeezes the spring 13, and the wedge-shaped limit rod 10 disengages from the gear 11. At this time, the gear 11 is released from the restriction, the coil spring 9 releases the elastic force, and drives the rotating shaft 6 to return to its original position and rotate clockwise. The rotating shaft 6 drives the extrusion rod 5 to move in the direction away from the stator winding 3 through the deep section of the arc groove 7, thereby achieving the purpose of demolding the stator winding 3.

[0055] For details, see Figure 1 The positioning assembly includes a plurality of positioning blocks 14, which together enclose a space for housing 25. The positioning blocks 14 are slidably mounted on the top surface of the processing table 2. Each of the processing tables 2 is equipped with a driver for moving the positioning blocks 14. In this embodiment, the driver is a first cylinder 15. Multiple first cylinders 15 operate synchronously, ensuring that the movement of the positioning blocks 14 is uniform.

[0056] When the casing 25 needs to be fixed, the casing 25 is first placed on the positioning cylinder 4, and then multiple first cylinders 15 are started at the same time. The first cylinders 15 drive the positioning clamps 14 to move toward the casing 25. At this time, multiple positioning clamps 14 clamp the casing 25 together, and the casing 25 is centered on the positioning cylinder 4 as the axis and limited on the surface of the processing table 2.

[0057] It is worth noting that see Figure 7 The inner wall of the positioning clamp 14 is provided with a receiving groove 16 , in which a drying tube 17 is installed. The drying tube 17 is electrically connected to a power source.

[0058] After the glue filling is completed, the drying tube 17 is started. At this time, the drying tube 17 dries and heats the housing 25, thereby accelerating the curing of the glue.

[0059] See also Figure 3 To facilitate the sealing of the housing 25 and the top of the stator winding 3, a lifting plate 18 is mounted on the fixture frame 1. The bottom surface of the lifting plate 18 is fixedly connected to the upper cover 19, and the bottom surface of the upper cover 19 is fixedly connected to the inner pressure plate 20. A lifting member is mounted on the fixture frame 1. In this embodiment, the lifting member is a second cylinder 21, the driving end of which is fixedly connected to the top surface of the lifting plate 18. A glue injection hole 22 is penetrated through the top surfaces of the lifting plate 18 and the upper cover 19.

[0060] When pouring concrete into the gap between the housing 25 and the stator winding 3, the second cylinder 21 is activated. The driving end of the second cylinder 21 drives the lifting plate 18 downward, which in turn drives the upper cover 19 and the inner pressure plate 20 downward. Due to the height difference between the housing 25 and the stator winding 3, the upper cover 19 is now sealed to the top of the housing 25, and the inner pressure plate 20 is now sealed to the top of the stator winding 3. Glue is then injected into the gap through the glue injection hole 22 until the gap between the housing 25 and the stator winding 3 is completely filled with glue.

[0061] It is worth noting that see Figure 8 Since the diameters of stator windings 3 of different specifications are different, in order to meet the requirements of the inner pressure plate 20 sealing the top of the stator winding 3, the inner pressure plate 20 includes an inner ring sub-plate 23 and an outer ring sub-plate 24. The inner ring sub-plate 23 is fixed to the bottom surface of the upper cover 19, and the outer ring sub-plate 24 is tightly fitted on the outer wall of the inner ring sub-plate 23.

[0062] In actual applications, stator windings 3 of different specifications have different diameters. In order to facilitate the inner pressure plate 20 to cover the stator winding 3, the diameter of the outer ring sub-plate 24 is selected according to actual needs until the sum of the diameters of the inner ring sub-plate 23 and the outer ring sub-plate 24 meets the requirements of covering the top of the stator winding 3.

[0063] In a second aspect, a glue potting process for a brushless motor stator includes the following steps:

[0064] S1: Pre-assembly: First, the housing 25 is placed on the positioning cylinder 4, and then multiple first cylinders 15 are started simultaneously. The first cylinders 15 drive the positioning clamps 14 to move toward the housing 25. At this time, multiple positioning clamps 14 clamp the housing 25 together. The housing 25 is centered on the processing table 2 with the positioning cylinder 4 as the axis. Finally, the stator winding 3 is pre-assembled in the housing 25;

[0065] S2: Positioning: This drives the shaft 6 to rotate counterclockwise. Guided by the positioning cylinder 4, the shaft 6 passes through the shallow end of the arc slot 7, driving the extrusion rod 5 to move horizontally toward the stator winding 3. At this point, the extrusion rod 5 presses against and presses against the inner wall of the stator winding 3. When the shaft 6 is released, the wedge-shaped stopper 10 is unidirectional, and with the cooperation of the spring 13, the shaft 6 is held stationary via the gear 11. This ensures that the extrusion rod 5 always presses against the inner wall of the stator winding 3, and the stator winding 3 is centered and confined within the housing 25.

[0066] S3: Covering. Start the second cylinder 21. The driving end of the second cylinder 21 drives the lifting plate 18 to descend. The lifting plate 18 drives the upper cover 19 and the inner pressure plate 20 to descend. Due to the height difference between the housing 25 and the stator winding 3, the upper cover 19 is now sealed at the top of the housing 25, and the inner pressure plate 20 is now sealed at the top of the stator winding 3.

[0067] S4: Glue filling, and then inject glue into the gap through the glue filling hole 22 until the glue fills the gap between the housing 25 and the stator winding 3;

[0068] S5: Drying, start the drying tube 17, and then the drying tube 17 dries and heats the housing 25, thereby accelerating the curing of the glue;

[0069] S6: Demolding. Activate the second cylinder 21, which resets and ultimately raises the upper cover 19 and inner pressure plate 20. Activate the first cylinder 15, which resets and moves the positioning clamp 14 away from the housing 25. This pulls the wedge-shaped limit rod 10 away from the rotating shaft 6, compressing the spring 13 and disengaging the wedge-shaped limit rod 10 from the gear 11. Gear 11 is now freed, releasing the coil spring 9 and causing the rotating shaft 6 to reset and rotate clockwise. The rotating shaft 6 passes through the deep end of the arc slot 7, driving the squeeze rod 5 away from the stator winding 3. Finally, remove the entire housing 25, completing the glue filling process.

[0070] To sum up, 1. The moving mechanism drives multiple extrusion rods 5 to move at the same time, so as to meet the centering limit of stator windings 3 of different specifications, which is beneficial to improving the applicability of the glue potting tooling; 2. Through the steps of pre-installation, positioning, capping, glue potting, drying and demolding, the glue is finally filled and solidified between the stator winding 3 and the casing 25, which is beneficial to improving the stability of the brushless stator glue potting.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
