Description

[0002] A commutator, also known as a "commutator", is an important component on the armature of a DC motor and an AC commutator motor. It consists of many copper sheets separated by mica sheets and is cylindrical or disc-shaped. Each copper sheet is connected to several armature winding elements. When the armature rotates, the copper sheets successively contact the fixed brushes. In a DC motor, the alternating current in the armature winding is converted into direct current between the brushes through the brushes and the commutator; in an AC commutator motor, the frequency of the alternating current between the brushes meets the working requirements.

The good product collection mechanism 84 includes a second pushing component, a good product empty plate storage area 841, and a good product full plate storage area 842. The second pushing component includes a second belt 843, a second push plate 844 connected to the second belt 843, and a second stepper motor component 845 for driving the second belt 844. Two second telescopic cylinders 846 are oppositely disposed outside the good product empty plate storage area 841, and the output end of each second telescopic cylinder 846 is connected to a second clamping plate 847. When an empty plate is needed, the two second telescopic cylinders 846 drive the second clamping plates 847 to retract, and an empty plate is placed. The second stepper motor component 845 drives the second belt 843, and the second belt 843 drives the second push plate 844 to push the empty plate forward, pushing the empty plate to the position where the good products are to be placed. When a row of the empty plate is filled with good products, the second belt 843 continues to drive the second push plate 844 to push the empty plate forward, and so on. When the empty plate is full, the second belt 843 drives the second push plate 844 to push the empty plate forward to the good product full plate storage area 842. If after the two second telescopic cylinders 846 retract, the photoelectric sensor does not detect an empty plate for a long time, an alarm is given to prompt the replenishment of empty plates. A second lifting cylinder 8421 and four second clamping blocks 8422 respectively disposed at the four corners are provided at the good product full plate storage area 842. The second clamping blocks 8422 can retract or extend, and the bottom surface of the second clamping blocks 8422 is an inclined surface. The second lifting cylinder 8421 rises to stepwise push the second push plate 844 driven by the second belt 843 to lift the full plate filled with good products. At this time, the full plate presses against the second clamping blocks 8422 along the bottom surface of the second clamping blocks 8422, and the second clamping blocks 8422 retract. When the full plate is lifted in place, the second clamping blocks 8422 extend to clamp the full plate so that the full plate does not fall. When the photoelectric sensor above detects that the plates are full after the full plates accumulate, it indicates that the plates are already full, and an alarm is given to prompt an operator to take away the full plates filled with good products.

[0064] When the utility model is in use, the commutator output by the previous equipment is docked to the feeding mechanism 1. The feeding mechanism 1 transports the commutator 10 to the feeding port 22 of the material distribution mechanism 2. The material distribution cylinder 23 acts to lift the commutator 10. The first transfer cylinder 34 of the transfer mechanism 3 advances, and the first jaw cylinder 33 clamps the commutator 10. The second transfer cylinder 35 moves horizontally to move the commutator 10 to the next process. After arriving, the first jaw cylinder 33 releases, the first transfer cylinder 34 retracts, and the second transfer cylinder 35 retracts, facilitating the transfer of the next commutator. The commutator 10 is transferred to the outer circle waste blowing mechanism 44 by the transfer mechanism 3. The vertical cylinder 41 drives the air blowing cover 43 to cover the commutator 10. The first downward cylinder 441 drives the first mandrel 442 to extend into the inner hole of the commutator 10, and the air holes 431 blow air. The rotary motor 443 drives the commutator 10 to rotate, blowing away dust and other impurities on the outer circle of the commutator 10. The commutator 10 is transferred to the inner hole waste blowing mechanism 45 by the transfer mechanism 3. The second downward cylinder 451 drives the second mandrel 452, and blows air through the air duct 453 inside the second mandrel 452 to blow away dust and other impurities inside the inner hole of the commutator 10. The commutator 10 is transferred to the upper inner hole detection mechanism 51 by the transfer mechanism 3. The pressing cylinder 513 drives the first detection rod 514 to extend downward into the inner hole of the commutator 10 from top to bottom, and the current pressing stroke position is obtained through the first displacement measuring part 512 to judge whether the inner hole of the product meets the requirements. The commutator 10 is transferred to the lower inner hole detection mechanism 52 by the transfer mechanism 3. The rising cylinder 523 drives the second detection rod 524 to extend upward into the inner hole of the commutator 10 from bottom to top, and the current rising stroke position is obtained through the second displacement measuring part 522 to judge whether the inner hole of the product meets the requirements. If the upper inner hole detection mechanism 51 and / or the lower inner hole detection mechanism 52 detects that the inner hole of the product is defective, the inner hole defective gripping mechanism 81 acts to place the defective product at the inner hole defective collection mechanism 82; if both the upper inner hole detection mechanism 51 and the lower inner hole detection mechanism 52 detect that the product is an OK product, this station does not act. The commutator 10 is transferred to the withstand voltage test mechanism 6 between the copper sheet and the inner hole by the transfer mechanism 3. The first positioning cylinder 64 first descends, and the first positioning rod 65 extends into the inner hole of the product. The first lifting cylinder 661 drops. After arriving, the first dialing cylinder 631 dials the product to drop the product into the first jig 62. The first up and down cylinder 61 drives a plurality of first probes 67 to press down to test the product. Each first probe 67 corresponds to 1 commutator copper sheet to form 1 path, and the first positioning rod 65 forms 1 path, which is connected to the withstand voltage detector, and high voltage is applied to see if there is breakdown between the copper sheet and the inner hole, etc. The result is output to the control system through the withstand voltage detector. When the detection result is defective, it is memorized by the control system and moved to the defective discharge mechanism 85 between the copper sheet and the inner hole. The first push-pull cylinder 851 pulls back the first push-pull plate 852, and the defective product falls into the defective product box between the copper sheet and the inner hole below; if this memorized product is an OK product, the first push-pull cylinder 851 of this station does not act.The commutator 10 is transferred by the transfer mechanism 3 to the withstand voltage testing mechanism 7 between copper sheets. First, the second positioning cylinder 74 moves downward, and the second positioning rod 75 extends into the inner hole of the product. Then, the second lifting cylinder 761 descends. After reaching the position, the second feeding cylinder 731 toggles the product and drops it into the second fixture 72. The second up-and-down cylinder 70 drives multiple second probes 77 to press down for testing the product. Each second probe 77 corresponds to one copper sheet of the commutator. The odd-numbered copper sheets are made into one circuit, and the even-numbered copper sheets are made into one circuit, which are connected to a withstand voltage detector. A high voltage is applied to check whether there is a short circuit between adjacent copper sheets, etc. The result is output by the withstand voltage detector to the control system. When the detection result is defective, it is memorized by the control system, and the product is moved to the defective product discharging mechanism 86 between copper sheets. The second push-pull cylinder 861 drives the second push-pull plate 862 to retract, and the defective product drops into the defective product box below between copper sheets. If this memorized product is a qualified product, the second push-pull cylinder 861 at this station does not act. The result of the product at the defective product discharging mechanism 86 between copper sheets is memorized by the program. If it is a qualified product, the second horizontal movement mechanism 831 acts, and the second lifting cylinder 832 drives the third jaw cylinder 833 to clamp the qualified product and rise. The second horizontal movement mechanism 831 moves to place the qualified product at the qualified product collecting mechanism 84. If the product is a non-conforming product, the qualified product gripping mechanism 83 does not act.
