Description

Technical Field

[0002] Coreless motors are DC, permanent magnet, servo micro motors with advanced technology, including outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operation characteristics, and are widely used in many fields.

[0003] The stator of a hollow core motor typically includes a drawing tube, magnets, a housing, and two bearings. The two bearings are located at both ends of the inner cavity of the drawing tube, the drawing tube is located inside the inner cavity of the magnet, and the magnet is located inside the inner cavity of the housing. The stator production process is extremely complex, involving feeding the drawing tube, magnets, and housing; assembling the drawing tube and magnets; assembling the housing and bearings; and drilling holes in the bearings. This results in very low efficiency for manual feeding and assembly. Furthermore, the stator's small size necessitates high precision in assembly, making it prone to misalignment of the housing and bearings during stator assembly, frequently leading to defective products.

[0081] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0082] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0083] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0084] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0085] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. "A plurality" means two or more.

[0086] Please see Figure 1 and Figure 2 The stator of the hollow cup motor provided in this application embodiment includes a drawing tube 1, a magnet 2, a housing 3, a first bearing 4, and a second bearing 5;

[0087] The pull tube 1 is installed inside the magnet 2, with one end of the pull tube 1 inside the magnet 2 and the other end of the pull tube 1 outside the magnet 2; the magnet 2 is entirely located inside the housing 3, and the end of the pull tube 1 located outside the magnet 2 is connected to the housing 3, with a portion of the pull tube 1 still located outside the housing 3; the first bearing 4 is installed at the end of the pull tube 1 located inside the magnet 2, and the second bearing 5 is installed at the end of the pull tube 1 located outside the housing 3.

[0088] It should be noted that the tube assembly in this application includes a pre-assembled tube 1 and a magnet 2. The process of inserting one end of the tube 1 into the magnet 2 is completed using other equipment. Then, the assembly equipment for the hollow cup motor stator provided in this application is used for assembling the housing 3, the first bearing 4, the second bearing 5, and drilling bearing holes. This is because, during the assembly of the tube 1 and the magnet 2, adhesive needs to be applied to the connecting part of the tube 1 and the magnet 2 to fix the tube 1 and the magnet 2. However, due to the long curing time of the adhesive, completing the assembly process of a hollow cup motor stator takes a long time. Therefore, the assembly process of the tube 1 and the magnet 2 is performed separately using other equipment. After assembly, the subsequent processes are performed using the assembly equipment for the hollow cup motor stator provided in this application. In this way, the subsequent steps are not delayed due to waiting for the assembly of the tube 1 and the magnet 2, which helps to improve the assembly efficiency of the hollow cup motor stator.

[0089] It should be noted that the first direction mentioned in this application refers to the length direction of the box 11, i.e., the X direction in the figure; the second direction refers to the width direction of the box 11, i.e., the Y direction in the figure; and the height direction of the box 11 is the Z direction in the figure. The meanings of the above directions are only for the purpose of explaining this application and should not be construed as limiting the technical solution of this application.

[0090] Please see Figures 3 to 5 The assembly equipment for the hollow cup motor stator provided in this application embodiment includes a base 10, an assembly mechanism 20, a first feeding mechanism 30, a second feeding mechanism 40, a third feeding mechanism 50, an opening mechanism 60, and a discharge mechanism 70.

[0091] The assembly mechanism 20 is provided with a first station for assembling the housing and the tube assembly, a second station for assembling the first bearing, the second bearing and the tube, and a third station for drilling holes in the first bearing and the second bearing. The assembly mechanism 20 is mounted on the base 10.

[0092] The first feeding mechanism 30 is used to transport the tube drawing assembly to the area below the first station. The first feeding mechanism 30 is installed on the machine base 10 at the position corresponding to the first station.

[0093] The second feeding mechanism 40 is used to transport the machine casing to the top of the first station. The second feeding mechanism 40 is installed on the machine base 10 at the position corresponding to the first station.

[0094] The third feeding mechanism 50 is used to transport the first bearing and the second bearing to the area below the second station. The third feeding mechanism 50 is installed on the machine base 10 at the position corresponding to the second station.

[0095] The hole-opening mechanism 60 is used to open holes in the first bearing and the second bearing. The hole-opening mechanism 60 is installed on the machine base 10 at the position corresponding to the third station.

[0096] The discharge mechanism 70 is used to collect the stator of the hollow cup motor after completing the above processes. The discharge mechanism 70 is installed on the machine base 10.

[0097] In application, the first feeding mechanism 30, the second feeding mechanism 40, and the third feeding mechanism 50 are used to transport the tube assembly, the housing, the first bearing, and the second bearing. The assembly mechanism 20 and the hole-opening mechanism 60 are used to assemble the housing, install the first and second bearings, and open the through holes of the first and second bearings, ultimately obtaining a complete motor stator. Finally, the discharge mechanism 70 collects the components. By combining multiple processes into one device, the assembly efficiency of the hollow cup motor stator is improved. By placing the three stations for housing assembly, bearing assembly, and bearing through hole opening on one mechanism of the assembly equipment, the volume of the assembly equipment can be effectively reduced and the space utilization rate can be improved.

[0098] In one embodiment, see Figure 4 , Figure 6 and Figure 7 The assembly mechanism 20 includes a first pressing component 21 and a second pressing component 22; the first pressing component 21 is located above the first station, and the second pressing component 22 is located above the second station and the third station.

[0099] The first pressing assembly 21 includes a first pressing rod 211 for pressing down the housing so that the pull tube is inserted into the housing and a first cylinder 212, the first cylinder 212 being used to drive the first pressing rod 211 to press down;

[0100] The second pressing assembly 22 includes a second pressing rod 221, a third pressing rod 222, and a second cylinder 223. The second cylinder 223 is used to drive the second pressing rod 221 and the third pressing rod 222 downward. The second pressing rod 221 is used to press down the housing that has been assembled with the tube drawing assembly so that the first bearing and the second bearing can be installed at both ends of the tube drawing assembly. The third pressing rod 222 is used to press down the housing that has been assembled with the first bearing and the second bearing to the opening mechanism 60.

[0101] In application, the first pressing assembly 21 also includes a detector 213 for detecting the incoming material direction of the housing. The detector 213 has a detection needle 2131 arranged parallel to the first pressing rod 211. The detection needle 2131 moves up and down synchronously with the first pressing rod 211, pressing the housing while simultaneously detecting the incoming material direction of the housing, ensuring that the housing is upright and the opening is facing downwards; thus, it can be ensured that the tube pulling assembly can be installed into the housing.

[0102] In one embodiment, see Figure 6 and Figure 7 The first pressing rod 211 has a first clearance groove 2111 at one end near the first station for inserting one end of the pull tube, and the second pressing rod 221 has a first clearance groove 2111 at one end near the second station for inserting one end of the pull tube.

[0103] The bottom of the first clearance groove 2111 is provided with a second clearance groove 2112 for the second feeding mechanism 40 and the third feeding mechanism 50 to be inserted.

[0104] In another embodiment, please refer to Figure 6 and Figure 7The second pressing rod 221 has a first clearance groove 2111 at one end near the second working position for inserting one end of the drawing tube; the bottom of the first clearance groove 2111 has a second clearance groove 2112 for inserting the second feeding mechanism 40 and the third feeding mechanism 50. With this configuration, the groove wall of the first clearance groove 2111 can limit the drawing tube, providing resistance and limiting during the assembly of the machine housing, the first bearing, and the second bearing; the second clearance groove 2112 is for inserting the second feeding mechanism 40 and the third feeding mechanism 50, thereby achieving a tight assembly effect.

[0105] In application, the cross-sectional area of ​​the first clearance groove 2111 is larger than that of the second clearance groove 2112. Thus, the groove walls of the first clearance groove 2111 and the second clearance groove 2112 form a stepped structure to limit the pulling of the tube and to make way for the second feeding mechanism 40 and the third feeding mechanism 50.

[0106] In one embodiment of this application, please refer to Figure 6 and Figure 8 The assembly mechanism 20 includes an upper top assembly 23 installed between the first feeding mechanism 30 and the first work station;

[0107] Top component 23 is used for:

[0108] Push the tube assembly into the first work station;

[0109] The first and second bearings are pushed into the second working position; and...

[0110] The hollow cup motor stator with the hole completed is pushed into the third station.

[0111] In one embodiment of this application, please refer to Figure 6 and Figure 8 The upper top assembly 23 includes a first drive member 231 installed in the base 10 and an upper top plate 232 connected to the output end of the first drive member 231.

[0112] The upper top plate 232 is provided with a first positioning groove 2321 for cooperating with the first feeding mechanism 30 to limit the position of the tube drawing assembly, a second positioning groove 2322 for cooperating with the third feeding mechanism 50 to limit the position of the first bearing and the second bearing, and a third positioning groove 2323 for limiting the position of the hollow cup motor stator. In this way, the upper top plate 232 can easily push the tube drawing assembly, the first bearing, the second bearing, and the hollow cup motor stator into the first station, the second station, and the third station, respectively.

[0113] In one embodiment of this application, please refer to Figure 9 and Figure 10The assembly mechanism 20 includes a movable component 24 mounted on the base 10; the movable component 24 includes a second drive member 241 and a movable plate 242 connected to the output end of the second drive member 241; the movable plate 242 has three first through holes for the housing to pass through, and the three first through holes respectively form a first station, a second station and a third station.

[0114] In one embodiment, a limiting sleeve 243 is installed on the movable plate 242 corresponding to the position of each first through hole. The limiting sleeve 243 has a second through hole 2430 for the housing to pass through. The limiting sleeve 243 includes a limiting part 2431 provided on the movable plate 242 and a fixing part 2432 for fixing the housing.

[0116] The upper push assembly 23 pushes the tube-pulling assembly into the second through hole 2430 of the limiting sleeve 243, while the first lower push assembly 21 presses the housing into the second through hole 2430 for assembly with the tube-pulling assembly. After assembly, it is fixed by the fixing part 2432 and moved above the third feeding mechanism 50 by the moving assembly 24 to complete the bearing assembly. In application, the first drive component 231 and the second drive component 241 can be a motor or a cylinder.

[0157] The working steps of the assembly equipment for the hollow cup motor stator provided in this application are as follows:

[0158] Feeding of the tube-pulling assembly: The tube-pulling assembly is sucked by the suction part 3312. The third cylinder 332 drives the suction part 3312 to move toward the discharge chute located at the first discharge hole. The fourth pressing rod 333 moves downward under the drive of the fourth cylinder 334, causing the tube-pulling assembly to disengage from the suction part 3312 and fall toward the second positioning member 325. The fifth cylinder 323 drives the first slider 322 to move, so that it moves to below the first station and cooperates with the first positioning groove 2321. The upper top plate 232 moves upward under the drive of the first driving member 231, pushing the tube-pulling assembly into the first station.

[0159] Feeding of the housing: The housing vibratory plate 41 feeds the housing through the feeding trough 410 into the first guide trough 4210 and moves toward the position of the second dropping hole. The limiting member 422 limits the height of the housing to prevent the housing from deflecting. The first pressing rod 211 moves downward under the drive of the first cylinder 212, so that the housing falls into the first working position.

[0160] Assembly of the housing and the tube pulling assembly: The upper push assembly 23 and the first pressing assembly 21 cooperate to realize the assembly of the tube pulling assembly and the housing, and are fixed in the fixing part 2432 of the limiting sleeve 243;

[0161] First movement: After the assembly of the tube drawing assembly and the housing is completed, the moving plate 242 moves from the first station to the second station under the drive of the second driving component 241, so that the assembled tube drawing assembly and the housing are positioned above the third feeding mechanism 50.

[0162] Feeding of the first bearing: The bearing vibratory feeder 51 feeds the first bearing into the connection between the second guide groove 5310 and the mounting groove 5312. The pusher block 5321, driven by the seventh cylinder 5323, pushes the first bearing towards the third drop hole 5311, causing it to fall from the third drop hole 5311 onto the fourth positioning member 525. Then, the sixth cylinder 523 drives the second slider 522 to move downwards towards the second pressing assembly 22. It is worth noting that the first bearing has already been transported to below the second workstation position at the same time as or before the completion of the first workstation movement step. It should be explained that the second workstation here refers to the position of the second workstation before the workstation movement; after the workstation movement, the first workstation moves to the original spatial position of the second workstation, and the second workstation is located in the original spatial position of the third workstation.

[0163] Assembly of the first bearing: The second pressing rod 221 presses down and cooperates with the upper push assembly 23 to install the first bearing into the lower end of the pull tube from below;

[0164] Feeding of the second bearing: The specific feeding process is the same as that of the first bearing, except that during the feeding process of the second bearing, the component that completes the assembly of the first bearing is located on the second slider 522, the third positioning component 524 positions and fixes the housing, and the fourth positioning component 525 positions the second bearing to facilitate the transportation of the second bearing.

[0165] Assembly of the second bearing: The second pressing rod 221 is pressed down to press the second bearing from the top of the pull tube into the pull tube;

[0166] Second movement: The second station moves to the space where the third station was originally located, realizing the movement of the motor stator that has completed the assembly process, so that it is located above the hole-opening mechanism 60;

[0167] Opening: The third pressing rod 222 presses the motor stator with the opening into the positioning sleeve 621, the clamping member 622 clamps the machine housing, the driver 612 and the eighth cylinder 613 drive the drill chuck 6111 to rotate and move upward, thus realizing the opening of the first bearing and the second bearing.

[0168] Third movement: The third station moves above the discharge mechanism 70;

[0169] Discharge: Under the blowing of the first air blowing component 71, the hollow cup motor stator that has completed all processes is blown off from the fixed plate and falls into the receiving box 72.

[0170] It should be understood that the order of the steps in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0171] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
