Description

Technical Field

[0001] The present invention relates to the technical field of commutator automatic detection, and in particular to a commutator full-automatic detection method and an assembly line thereof. Background Art

[0002] The commutator, also known as the "rectifier," is a crucial component in the armature of DC and AC commutator motors. It is composed of a cylindrical or disc-shaped assembly of copper plates separated by mica sheets, each connected to several elements of the armature winding. As the armature rotates, the plates successively come into contact with fixed brushes. In DC motors, the brushes and commutator convert the AC current in the armature winding into DC current between the brushes. In AC commutator motors, the commutator ensures that the frequency of the AC current between the brushes meets operating requirements.

[0003] Chinese patent document 2019111389355 discloses a fully automatic commutator withstand voltage detection device and its use method, the method is: step one, loading stage; S1: transfer the commutator to the groove of the fixed seat; step two, sheet shaft withstand voltage detection stage and / or inter-sheet withstand voltage detection stage; S2: rotate the turntable counterclockwise to transfer the commutator to the sheet shaft withstand voltage detection mechanism and / or inter-sheet withstand voltage detection mechanism; the detection process of the sheet shaft withstand voltage detection mechanism is: the connecting seat moves downward, so that the conductive column extends into the commutator shaft hole, and the copper ring abuts against the commutator hook; the first high-voltage tester starts working, transmits high voltage to the conductive column and the copper ring, and performs a high-voltage withstand voltage test of more than 3000V, detects the conductive performance between all commutator contact pieces and the commutator shaft holes, and sends the detection information to the controller. If leakage current is detected between the commutator contact piece shafts, the controller will judge the commutator as unqualified. ; The detection process of the inter-piece voltage resistance detection mechanism is as follows: the fixed disk is close to the commutator, so that the steering rod is inserted between the two adjacent commutator hooks; the second cylinder pushes the second push plate close to the commutator, so that the two measuring needles are respectively in contact with the two adjacent commutator contact pieces; the second high-voltage tester starts to work, and transmits high voltage electricity to the measuring needle to perform a high-voltage resistance test of more than 500V to detect the conductive properties of the two adjacent commutator contact pieces. After the detection is completed, the first drive motor drives the rotating shaft to rotate, and the rotating shaft drives the commutator to rotate one circle through the steering rod. The two measuring needles respectively contact each commutator contact piece to detect the conductive properties of each commutator contact piece and send the detection information to the controller. If a leakage circuit is detected between the commutator contact pieces, the controller will judge the commutator as unqualified; Step three, unloading stage; S3: Rotate the turntable counterclockwise to unload the qualified commutators and unqualified commutators respectively.

[0004] In the above patent, when performing the inter-piece voltage withstand test, the commutator needs to be rotated while the test is being performed, and the test can only be performed between two adjacent contact pieces. The conductive performance between any two contact pieces cannot be tested. The test is not comprehensive enough and it is easy for unqualified products to flow out. Summary of the Invention

[0013] By adopting the above technical solution, the transfer mechanism moves the commutator to the bottom of the sleeve, and then the lifting mechanism drives the commutator to rise. The photoelectric sensor can detect whether the current copper bar corresponds to the probe. When the copper bar on the commutator rotates to the position corresponding to the probe, the lifting mechanism drives the commutator to rise again, so that the copper bar and the probe are detected for detection; after the detection is completed, the lifting mechanism drives the commutator to move down and place it on the detection platform.

[0014] The present invention is further configured as follows: the structures of the one-way detection mechanism between sheets, the sheet axis withstand voltage detection mechanism, and the two-way detection mechanism between sheets are the same; the high-voltage tester applies a voltage of 400V-600V to the probes on the one-way detection mechanism between sheets and the two-way detection mechanism between sheets; the high-voltage tester applies a voltage of 1000V to the probes on the sheet axis withstand voltage detection mechanism; and the voltage of the probes on the two-way detection mechanism between sheets is greater than the voltage of the probes on the one-way detection mechanism between sheets.

The action is more efficient and the detection efficiency is higher.
