Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, and in particular discloses a vibratory feeder feeding mechanism for a carbon brush machine and a carbon brush machine. Background Technology

[0002] In traditional carbon brush assembly equipment, the vibratory feeder mechanism often leads to assembly failure due to inconsistent carbon brush spring postures, especially when the carbon brush has a bent spring structure. Existing vibratory feeders struggle to automatically correct the spring posture during transport. Current technologies often rely on manual intervention or additional robotic arms for adjustment, which is not only inefficient but also prone to secondary deformation of the springs due to random collisions during vibration transport. Some improvements attempt to add guide structures to the linear track, but these cannot solve the problem of posture correction during the transition from the spiral feeding section to the linear section. This results in spring orientation deviations still existing when the carbon brush enters the assembly station, affecting subsequent pressing accuracy. Utility Model Content

[0003] In order to overcome the difficulty of automatically correcting the spring posture during the conveying process in the existing vibratory feeder, the purpose of this utility model is to provide a vibratory feeding mechanism and carbon brush machine that uses the bending shape of the spring itself for automatic carbon brush correction.

[0004] To achieve the above objectives, this utility model provides a vibratory feeder mechanism for a carbon brush machine, comprising a vibratory feeder body and a vibration driver connected to the vibratory feeder body. The vibratory feeder body is provided with a spiral feeding track, which is connected to a first sorting track. Multiple external carbon brushes move along the spiral feeding track to the first sorting track under the vibration of the vibratory feeder body and are output through the first sorting track. The first sorting track has an arc-shaped guide surface, which abuts against the bent portions of the springs that engage with the multiple external carbon brushes. The bent portions of the springs of the multiple external carbon brushes are adjusted to a preset posture via the arc-shaped guide surface of the first sorting track. The multiple external carbon brushes in the preset posture enter the first sorting track for use with the carbon brush assembly device of the external carbon brush machine.

[0005] Furthermore, the first sorting track includes two adjusting plates disposed at the output end of the spiral feeding track. The two adjusting plates are arranged in an arc shape and are spaced apart to form a guide groove. The bent part of the spring is used to abut against the arc-shaped convex surface of one adjusting plate, and the abutting block of the carbon brush is used to abut against the arc-shaped concave surface of the other adjusting plate. The arc-shaped convex surface and the arc-shaped concave surface are arc-shaped guide surfaces.

[0006] Furthermore, the extension direction of the first sorting track is intersected with the vibration direction of the vibratory feeder body, so that the carbon brush generates directional torque during the vibration conveying process of the vibratory feeder body.

[0007] Furthermore, the guide groove formed by the two adjusting plates has an inlet section and an outlet section. The inlet section of the guide groove cooperates with the discharge end of the spiral feeding track, and the outlet section of the guide groove cooperates with the feed inlet of the linear conveying track.

[0008] Furthermore, the spacing between the two adjustment plates is set to gradually decrease from the inlet section to the outlet section.

[0009] Furthermore, the bottom of the vibration driver is provided with multiple shock-absorbing pads, which are arranged around the central axis of the vibratory disk body.

[0010] Furthermore, the vibratory feeder feeding mechanism for the carbon brush machine also includes a linear conveying track that is configured to cooperate with the vibratory feeder body. The first sorting track is located between the spiral feeding track and the linear conveying track. Multiple external carbon brushes in a preset posture first enter the first sorting track and then are output via the linear conveying track, for use in conjunction with the carbon brush assembly device of the external carbon brush machine.

[0011] Furthermore, the vibratory feeder feeding mechanism also includes a material distribution component and a temporary storage section. The material distribution component is located at the free end of the linear conveyor track to separate multiple carbon brushes conveyed by the linear conveyor track into individual carbon brushes. The temporary storage section is used to receive the individual carbon brushes separated by the material distribution component for use with the carbon brush assembly device of an external carbon brush machine.

[0012] Furthermore, the material distribution assembly includes a first driving component, a material distribution plate disposed at the output end of the first driving component, and a first support frame disposed in cooperation with the material distribution plate. The material distribution plate is reciprocatingly disposed on the first support frame. The moving direction of the material distribution plate is intersected with the feeding extension direction of the linear conveying track. Under the vibration conveying of the vibrating plate body, the linear conveying track moves multiple carbon brushes sequentially to the first support frame. The first driving component is used to drive the material distribution plate to abut against a single carbon brush on the first support frame and transfer it to the temporary storage section for limiting. The transfer feeding mechanism of the external carbon brush assembly device is used to pick up the carbon brush limited in the temporary storage section.

[0013] Furthermore, the material distribution assembly also includes a transfer station, a second driving component disposed on the transfer station, and a material picker disposed at the output end of the second driving component. The temporary storage unit includes a temporary storage rack disposed on the transfer station and a temporary storage slot disposed on the temporary storage rack. The first driving component is used to drive the material distribution plate to move to the transfer station, and the second driving component is used to drive the material picker to pick up the carbon brushes transferred by the material distribution plate and transfer them to the temporary storage slot.

[0014] This utility model discloses a carbon brush machine, comprising a frame, a transfer feeding device, an assembly device, and a stator placement mechanism arranged sequentially on the frame. The vibratory feeder feeding mechanism for the carbon brush machine is used to feed external carbon brushes into the transfer feeding device. The transfer feeding device is used to receive carbon brushes fed by the vibratory feeder feeding mechanism and transfer them to the assembly device. The stator limiting device includes a stator fixing seat, on which an external stator is mounted. The transfer feeding device includes a picking component and a pressing pin assembly used in conjunction with the picking component. The picking component is used to pick up the carbon brushes transferred by the transfer feeding device and deliver them to the assembly device. The pressing pin assembly is used to press the carbon brushes into the assembly device by contacting them. The assembly device is used to press the carbon brushes pressed in by the pressing pin assembly into the external stator limited by the stator limiting device. The feeding device is the vibratory feeder feeding mechanism for the carbon brush machine.

[0015] The core of this invention lies in setting a first sorting track with an arc-shaped guide surface between the spiral feeding track and the linear conveying track, forming a progressive correction channel through guide grooves composed of double adjustment plates. During the vibration conveying process, the spring bending part of the carbon brush generates directional torque due to the continuous contact of the arc-shaped convex surface, while the carbon brush contact block is limited by the arc-shaped concave surface, forcing the spring bending part to be adjusted to a preset angle during movement. The extension direction of the sorting track is arranged intersecting the vibration direction, and the tangential force generated by the vibration vector decomposition promotes the rotation of the carbon brush, which, together with the gradually narrowing guide groove spacing, completes the posture screening. The coordinated design of the sorting component and the temporary storage part further ensures the precise positioning of the single carbon brush, meeting the cycle time requirements of high-speed assembly.

[0016] The beneficial effects of this utility model are as follows: Through the arc-shaped guide surface design of the first sorting track, the carbon brush spring bending part can be automatically and efficiently adjusted to the preset posture, ensuring that the carbon brush enters the straight conveying track in a uniform direction, which significantly improves the assembly accuracy and yield.

[0017] Meanwhile, the cross arrangement of the sorting track and the vibration direction, as well as the gradual spacing design of the guide groove, enable the mechanism to have adaptive screening capabilities, be compatible with carbon brushes of different sizes, and reduce material jamming and the retention of abnormal products.

[0018] In addition, the collaborative work of the material distribution component and the temporary storage section enables precise separation and positioning of carbon brushes, meeting the high-efficiency cycle requirements of automated assembly. The overall structure is compact and stable, greatly reducing the need for manual intervention, and is suitable for high-precision, large-volume automated carbon brush assembly scenarios.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] Please see Figures 1 to 5 As shown, the vibratory feeder feeding mechanism for carbon brush machine of this utility model includes a vibratory feeder body 1. A vibration driver 2 is coaxially connected to the bottom of the vibratory feeder body 1. The vibration driver 2 is preferably an electromagnetic vibrator. Its output end is rigidly fixed to the bottom plate of the vibratory feeder by bolts. It can drive the entire vibratory feeder body 1 to generate periodic vibration along the set vibration direction after being powered on.

[0023] Specifically, a spiral feeding track 11 is machined circumferentially on the upper surface of the vibratory plate body 1. The track is integrally stamped or milled, with its inner edge smoothly transitioning to the plate surface and its outer edge having a limiting stop to prevent the carbon brush 100 from coming off the track during vibration.

[0024] Specifically, the end of the spiral feeding track 11 is connected to the linear conveying track 3 through a first sorting track 12. The first sorting track 12 is made of rigid metal plate and is fixed on both sides to the upper edge of the vibrating plate body 1. Its main body is composed of two arc-shaped adjustment plates 13. The two adjustment plates 13 are arranged at intervals to form a through guide groove 131. The inlet end of the guide groove 131 is in close contact with the free end of the spiral feeding track 11, and the outlet end is connected to the feed port of the linear conveying track 3 to ensure that the carbon brush 100 transitions smoothly during the conveying process.

[0025] Specifically, the inner walls of the two adjusting plates 13 are respectively processed into an arc-shaped convex surface and an arc-shaped concave surface. The arc-shaped convex surface is set away from the central axis of the vibrating plate and is located on the side of the bent part of the spring 101. It can continuously abut against the bent part and apply a lateral torque when the carbon brush 100 moves, causing the spring 101 to rotate in a preset direction. The arc-shaped concave surface is located on the side of the carbon brush 100 abutting block and forms a limiting and guiding effect on the abutting block, so that the carbon brush 100 maintains a stable posture when passing through the guide groove 131.

[0026] Preferably, to enhance the correction effect, the distance between the two adjustment plates 13 gradually decreases from the inlet end to the outlet end, forming a progressive extrusion channel, so that the carbon brush 100 with incorrect posture is completely corrected before the outlet. The extension direction of the first sorting track 12 is at a certain intersection angle with the vibration direction of the vibrating disk body 1. The tangential component force generated by the vibration gives the carbon brush 100 a tendency to rotate while it moves forward, thereby accelerating the posture adjustment in conjunction with the arc-shaped guide surface.

[0027] To address the issue of chaotic posture of the carbon brush 100 in the initial stage of the spiral feeding section, a pre-posture adjustment structure is installed near the end of the spiral feeding track 11. This structure consists of a "high-pressure limiting bar + weighted guide wedge + inner inclined rib + misaligned baffle": the high-pressure limiting bar is suspended above the outer side of the track, and the minimum distance between the high-pressure limiting bar and the bottom surface is slightly greater than the thickness of the carbon brush 100's contact block, forcing the high-posture horizontally lying carbon brush 100 to lower its posture and enter the controlled window, i.e., the entrance end of the first sorting track 12; the weighted guide wedge is arranged on the outer side of the bottom surface of the spiral feeding track 11, with the wedge surface forming an upward angle of 10-20° with the bottom surface, and the contact block (with a mass greater than that of the spring 101 on one side) is adjusted accordingly. The carbon brush 100 tends to roll down to the low potential energy side under the action of vibration and gravity, forming an inclined posture with the contact block as the lower fulcrum. The inner inclined rib is set on the side near the center of the vibratory feeder, with the rib surface and the bottom surface forming an angle of 15-30°. It makes line contact with the bent part of the spring 101 of the carbon brush 100, restricting it from continuing to lie down and guiding it to generate a small self-rotation around the lower edge of the contact block. The misaligned baffle is located half a pitch in front of the outer edge of the first sorting track 12. The misaligned baffle extends into the first sorting track 12 by 10-20% of its width. It softly intercepts individuals that have not formed the target inclined posture of "contact block below, spring 101 above" and returns them to the previous turn to re-align. The above is a common structural design of the carbon brush 100 feeding vibratory feeder mechanism for reference.

[0028] Specifically, in this embodiment, the linear conveying track 3 is fixed on the outer support (not shown in the figure) of the vibratory feeder body 1 and is connected to the outlet end of the first sorting track 12. Its bottom surface is made of a low-friction material, and guide rails are provided on both sides of the track to ensure that the carbon brush 100 is output in a unidirectional linear manner. A material distribution assembly 4 is installed at the end of the linear track. The material distribution assembly 4 includes a first driving component 41, a material distribution plate 42, and a first support frame 43. The first support frame 43 is horizontally connected to the end of the linear track and is provided with a limiting groove (not shown in the figure) that matches the shape of the contact block 102 of the carbon brush 100 for temporarily receiving the carbon brush 100 from the linear conveying track 3.

[0029] Specifically, the separating plate 42 is movably arranged along the direction perpendicular to the extension of the linear track, and can reciprocate under the drive of the first driving member 41 (preferably a three-axis cylinder). When the carbon brush 100 conveyed by the linear track enters the first support frame 43, the first driving member 41 pushes the separating plate 42 to move laterally, pushing the individual carbon brush 100 on the first support frame 43 to the temporary storage section. The temporary storage section is located on the side of the separating assembly 4 and includes a temporary storage rack 51 set on the transfer table 44 and a temporary storage slot 52 opened on the temporary storage rack 51, for storing the separated carbon brushes 100 in sequence, ensuring that the transfer and feeding mechanism of the external carbon brush machine can accurately pick them up.

[0030] In another embodiment, the end of the material distribution plate 42 of the material distribution component 4 is connected to the transfer platform 44. The transfer platform 44 is equipped with a second drive component 45 and a material picker 46. The second drive component 45 is designed as a combination of a gripper cylinder and a linear cylinder, which can control the material picker 46 to clamp a single carbon brush 100 and move it in the horizontal direction (parallel to the extension direction of the linear conveyor track 3), pushing it into the temporary storage slot 52 on the temporary storage rack 51 to achieve flexible secondary transfer.

[0031] During operation, the vibration driver 2 drives the vibratory feeder body 1 and its spiral feeding track 11 and first sorting track 12 to generate high-frequency micro-amplitude vibrations. Under the action of vibration and gravity, the external carbon brushes 100 gradually rise along the spiral track and enter the first sorting track 12. Through the physical intervention of the arc-shaped guide surface and the limiting effect of the narrowing track, the bent parts of the springs 101 of the carbon brushes 100 are adjusted to a consistent orientation, and the carbon brushes 100 with the correct posture smoothly enter the straight track. The carbon brushes 100 with incorrect posture fall into the vibratory feeder body 1 for further sorting and feeding. Subsequently, under the continuous action of vibration, the carbon brushes 100 are sequentially fed into the sorting assembly 4 along the straight track, and are pushed or clamped one by one by the sorting mechanism to the temporary storage section, waiting to be picked up by the carbon brush machine assembly device 202.

[0032] Specifically, the present invention provides a carbon brush machine, comprising a frame 200, a feeding device, a transfer feeding device 201, an assembly device 202, and a stator placement mechanism 203 arranged sequentially on the frame 200. The feeding device is used to feed external carbon brushes 100 into the transfer feeding device 201. The transfer feeding device 201 is used to receive the carbon brushes 100 fed by the feeding device and transfer them to the assembly device 202. The stator limiting device includes a stator fixing seat 2031, and the external stator is used to be mounted on the stator fixing seat 2031. 1. The transfer and feeding device 201 includes a picking component 2011 and a pressing pin assembly used in conjunction with the picking component 2011. The picking component 2011 is used to pick up the carbon brush 100 transferred by the transfer and feeding device 201 and delivered to the assembly device 202. The pressing pin assembly is used to press the carbon brush 100 into the assembly device 202 by contacting it. The assembly device 202 is used to press the carbon brush 100 pressed in by the pressing pin assembly into the external stator limited by the stator limiting device. The feeding device is the vibratory feeder feeding mechanism for the carbon brush machine.
