Technical Field

[0001] This utility model relates to the technical field of processing equipment for hollow cup motors, and in particular to a commutator assembly feeding device for an automatic spot welding equipment for motor rotors. Background Technology

[0002] The coreless motor rotor includes a commutator assembly and winding coils. The commutator assembly includes a motor shaft, a rotor frame disposed around the outer periphery of the motor shaft, and a commutator connected to the rotor frame. Multiple sets of circumferentially distributed commutator segments are arranged on the upper surface of the commutator. The winding coils have pins corresponding to the commutator segments, and the pins of the winding coils are welded and fixed to the corresponding commutator segments. Currently, in the processing of coreless motor rotors, the commutator assembly is generally loaded manually, which is inefficient. Therefore, it is necessary to design an automatic loading device for the commutator assembly to improve automation. Summary of the Invention

[0003] The purpose of this invention is to provide a commutator assembly feeding device for an automatic spot welding equipment for motor rotors, which can realize automated feeding of commutator assemblies, thereby greatly improving the feeding efficiency of commutator assemblies.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a commutator assembly feeding device for an automatic spot welding equipment for motor rotors, comprising...

[0005] Vibratory feeder, used to orderly and orient commutator assemblies;

[0006] The material rack is fixedly installed at the output end of the vibratory feeder. The material rack has a material picking chamber with an upper opening and a feeding channel connecting the material picking chamber and the output end of the vibratory feeder. The inner end face of the material picking chamber has a support surface for supporting the commutator assembly.

[0007] The material handling mechanism includes an openable and closable gripper assembly, a first conveying assembly that drives the gripper assembly to reciprocate vertically, and a second conveying assembly that drives the gripper assembly to reciprocate longitudinally.

[0008] Furthermore, a positioning component is provided on the material rack. The positioning component can reciprocate between a locked position and an unlocked position. When the positioning component is in the locked position, it can position the commutator component in the material picking chamber at a set position. An unlocking block is provided on the side of the gripper component adjacent to the positioning component. When the gripper component moves down to the gripping position, the unlocking block drives the positioning component to move towards the unlocked position to unlock the positioning component from the commutator component, so that the gripper component can accurately grip the commutator component.

[0009] Furthermore, the positioning component includes a positioning plate and an elastic element. The shelf is provided with a guide channel that slides laterally with the positioning plate. The positioning plate passes through the guide channel and extends into the material taking chamber. The positioning plate has a positioning groove that opens towards the feeding channel. The commutator assembly is positioned in a set position by the groove wall of the positioning groove. The positioning plate tends to move towards the material taking chamber under the action of the elastic element. The shelf is provided with limiting plates on both sides corresponding to the positioning plate to restrict the movement stroke of the positioning plate.

[0010] Furthermore, the positioning plate has a limiting protrusion, a guide sliding part, and a positioning part. The elastic element abuts against the side of the limiting protrusion away from the material picking cavity. A guide inclined surface is provided on the side of the limiting protrusion adjacent to the material picking cavity. When the unlocking block descends, it abuts against the guide inclined surface and pushes the limiting protrusion to move toward the side of the compression elastic element. The guide sliding part slides with the guide channel. The positioning groove is provided on the side of the positioning part facing the feeding channel.

[0011] Furthermore, the gripper assembly includes a gripper cylinder and two gripper arms connected to the output end of the gripper cylinder. The gripping ends of the two gripper arms are provided with a gripping groove adapted to the outer periphery of the commutator assembly and a clearance groove for the rotor frame and motor shaft of the commutator assembly to pass through.

[0012] Furthermore, the width of the clamping arm is smaller than the width of the material handling chamber.

[0013] Furthermore, the material handling mechanism also includes a support frame, the second transfer component is fixedly connected to the top of the support frame and arranged longitudinally, the first transfer component is fixedly connected to the sliding part of the second moving component, and the gripper component is fixedly connected to the sliding part of the first transfer component.

[0014] In summary, the present invention has the following beneficial effects:

[0015] The commutator assembly feeding device of the automatic spot welding equipment for motor rotor of this utility model can realize the automatic feeding of commutator assemblies, thereby greatly improving the feeding efficiency of commutator assemblies. Specifically, the commutator assemblies are automatically sorted by the orientation of the vibratory feeder (the side with the shorter motor shaft is set upwards), and are orderly conveyed to the output end and enter the picking chamber of the shelf. The commutator assemblies are picked up by the gripper assembly of the picking mechanism and transferred to the processing station (the support seat of the multi-station rotary table).

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-9 As shown, a commutator assembly feeding device for an automatic spot welding equipment for motor rotors includes a vibratory plate 10, a material rack 20, and a material picking mechanism 30, which constitute the specific structure of this utility model. The automatic spot welding equipment for motor rotors includes a multi-station rotary plate (used for welding the commutator assembly 40 and the winding coil). This utility model uses a feeding device to automatically feed the commutator assembly 40.

[0028] The vibratory feeder 10 is used to transport the commutator assembly 40 in an orderly and oriented manner. Specifically, the vibratory feeder 10 automatically sorts the orientation of the commutator assembly 40 (with the shorter side of the motor shaft 41 facing upwards) and transports it to the output end in an orderly manner. The automatic sorting and orderly oriented transport of the commutator assembly 40 by the vibratory feeder 10 is existing technology and will not be described in this utility model.

[0029] The material rack 20 is fixedly installed at the output end of the vibratory feeder 10. The material rack 20 has a material picking chamber 21 with an upper opening and a feeding channel 22 connecting the material picking chamber 21 and the output end of the vibratory feeder 10. The inner end face of the material picking chamber 21 is provided with a support surface 211 for supporting the commutator assembly 40. The feeding channel 22 is provided with a support platform surface for supporting the commutator assembly 40. Furthermore, the width of the gripper arm 312 of the gripper assembly 31 is smaller than the width of the material picking chamber 21, so that the gripper arm 312 of the gripper assembly 31 can extend into the material picking chamber 21 to grip the commutator assembly 40.

[0030] The material handling mechanism 30 includes an openable and closable gripper assembly 31, a first transfer assembly 32 that drives the gripper assembly 31 to reciprocate vertically, and a second transfer assembly 33 that drives the gripper assembly 31 to reciprocate longitudinally, and grips and releases the commutator assembly 40 through the gripper assembly 31.

[0031] The material rack 20 is provided with a positioning component 23, which can reciprocate between a locked position and an unlocked position. When the positioning component 23 is in the locked position, it can position the commutator component 40 in the material picking chamber 21 at a set position. The gripper component 31 is provided with an unlocking block 34 on the side adjacent to the positioning component 23. The lower end of the unlocking block 34 is provided with an arc-shaped guide surface. When the gripper component 31 moves down to the gripping position, the unlocking block 34 drives the positioning component 23 to move toward the unlocking position to unlock the positioning component 23 from locking the commutator component 40, so that the gripper component 31 can accurately grip the commutator component 40.

[0032] The positioning assembly 23 includes a positioning plate 231 and an elastic element 232. The shelf 20 is provided with a guide channel that slides laterally with the positioning plate 231. The positioning plate 231 partially passes through the guide channel and extends into the material taking chamber 21. The positioning plate 231 has a positioning groove 2315 that opens towards the feeding channel 22. The commutator assembly 40 is positioned in a set position by the groove wall of the positioning groove 2315. Under the action of the elastic element 232, the positioning plate 231 tends to move towards the material taking chamber 21. The shelf 20 is divided into two sides corresponding to the positioning plate 231. A limiting plate 233 is provided to restrict the movement of the positioning plate 231. The limiting plates 233 on both sides are detachably and fixedly connected to the two sides of the shelf 20. The left limiting plate 233 is used to abut against the elastic member 232 on the one hand, and to limit the movement of the positioning plate 231 to the left and prevent it from falling off the shelf 20 (i.e., falling out of the shelf 20) on the other hand. The right limiting plate 233 cooperates with the limiting protrusion 2311 of the positioning plate 231 to limit the movement of the positioning plate 231 to the right.

[0033] The positioning plate 231 has a limiting protrusion 2311, a guide sliding part 2312, and a positioning part 2313. Specifically, the limiting protrusion 2311, the guide sliding part 2312, and the positioning part 2313 are integrally formed from left to right. The elastic member 232 abuts against the side of the limiting protrusion 2311 away from the material taking cavity 21. A guide inclined surface 2314 is provided on the side of the limiting protrusion 2311 adjacent to the material taking cavity 21. When the unlocking block 34 descends, it abuts against the guide inclined surface 2314 and pushes the limiting protrusion 2311 to move toward the side of the compression elastic member 232. The guide sliding part 2312 slides with the guide channel. The positioning groove 2315 is provided on the side of the positioning part 2313 facing the feeding channel 22.

[0034] The gripper assembly 31 includes a gripper cylinder 311 and two gripper arms 312 connected to the output end of the gripper cylinder 311. The gripping ends of the two gripper arms 312 are provided with a gripping groove 3121 that is adapted to the outer periphery of the commutator 43 of the commutator assembly 40 and a clearance groove 3122 for the rotor frame 42 and the motor shaft 41 of the commutator assembly 40 to pass through.

[0035] The material handling mechanism 30 also includes a support 35. The second transfer component 33 is fixedly connected to the top of the support 35 and arranged longitudinally. The first transfer component 32 is fixedly connected to the sliding part of the second moving component. The gripper component 31 is fixedly connected to the sliding part of the first transfer component 32. Specifically, the first transfer component 32 is a cylinder, preferably a slide cylinder. The second transfer component 33 can be a lead screw assembly or a slide module.

[0036] In summary, the present invention has the following beneficial effects:

[0037] The commutator assembly feeding device of the automatic spot welding equipment for motor rotor of this utility model can realize the automatic feeding of commutator assembly 40, thereby greatly improving the feeding efficiency of commutator assembly 40. Specifically, the commutator assembly 40 is automatically sorted by the vibratory plate 10 (the shorter side of the motor shaft 41 is set upwards), and is orderly conveyed to the output end and enters the picking chamber 21 of the shelf 20. The commutator assembly 40 is picked up by the gripper assembly 31 of the picking mechanism 30 and transferred to the processing station (the support seat of the multi-station rotary table).

[0038] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
