Description

Technical Field

[0001] This application relates to the field of commutator manufacturing, and in particular to an automatic processing device for commutators. Background Art

[0002] Commutators are mainly used in the motor industry. Commutators mainly have specifications such as hook type, groove type, and flat type. The commutator plays a commutation role, making the current direction in the armature winding alternating to ensure that the direction of the electromagnetic torque remains unchanged.

[0003] In related technologies, after the commutator is compression molded, the top of the commutator copper sheet needs to be milled to make it narrower to form the commutator hook part, and then the commutator hook part forms the welding wire hook of the commutator in the subsequent bending process. And the top of the commutator copper sheet needs to go through polishing, bending, and detection in sequence during the bending process.

[0004] Regarding the above related technologies, the inventor believes that the top of the commutator copper sheet needs to go through polishing, bending, and detection in sequence during the bending process, which is completed by manual transfer, resulting in a large labor intensity and there is still room for improvement.

[0129] If it passes the detection by the side image detection component 56, the upper side image detection component, and the lower side image detection component, the rotation driving source drives the conveying disk 581 to rotate by a first angle and waits for discharging. If it fails the detection by the side image detection component 56, the upper side image detection component, and the lower side image detection component, the rotation driving source drives the conveying disk 581 to rotate by a second angle and waits for recycling. Here, the first angle and the second angle are not equal.

The clamping portion 763 is fixed to one end of the connecting portion 762 away from the fixing portion 761 and extends vertically downward from the connecting portion 762. When the two clamping portions 763 are in contact with each other, the two clamping portions 763 can be inserted into the through hole of the commutator. After the two clamping portions 763 are inserted into the through hole of the commutator, the two clamping portions 763 are driven by the clamping drive source 75 to move away from each other and press against the inner side wall of the commutator to clamp the commutator.

[0134] Initially, the piston rods of the lowering drive source 74 and the clamping drive source 75 are both in the retracted state. During discharging, the lowering drive source 74 and the clamping drive source 75 are driven by the first linear module 72 and the second linear module 73 to move above the commutator on the conveying tray 581. The piston rod of the lowering drive source 74 extends to drive the clamping portion 763 to be inserted into the commutator, and the clamping drive source 75 drives the two clamping portions 763 to move away from each other to clamp the commutator. Subsequently, the piston rod of the lowering drive source 74 retracts, and the first linear module 72 and the second linear module 73 drive the lowering drive source 74 and the clamping drive source 75 to move above the aggregate tray 80. Then, the piston rod of the lowering drive source 74 extends to drive the commutator to be inserted into the aggregate tray 80. Then, the clamping drive source 75 drives the two clamping portions 763 to move closer to each other to release the commutator, and arranges the commutator in the aggregate tray 80, realizing the automatic collection and arrangement of qualified commutators.

[0135] The implementation principle of an automatic commutator processing device according to an embodiment of the present application is as follows: The commutator after compression molding is fed to a specified position by the feeding mechanism 20. The transfer mechanism 60 drives the commutator at the specified position to be polished by the polishing mechanism 30 in sequence, bent by the bending mechanism to form a hook, and subjected to short-circuit detection and image detection by the detection mechanism 50. Finally, the qualified commutators are arranged in the aggregate tray 80 by the discharging mechanism, realizing the automation of the commutator from after compression molding to complete molding.

[0136] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
