Carman Haas Hairpin Motor Laser Processing
The new energy industry is in a period of rapid development, more and more customers are involved in the production of Hairpin motor. Carman Haas have developed this Hairpin motor laser scanning welding system in response to the problems and needs encountered by customers in production. The customer needs are summarized and mainly include the following four points:
1: The demand for production efficiency, which requires fast beats, and compatibility with deviation welding spots as much as possible to improve the one-time pass rate;
2: The demand for welding quality, a product has hundreds of welding spots, requires high welding spot quality and appearance consistency, and low spatter during the welding process;
3: The solution to bad welding spots, how to repair them when encountering failure types such as welding spot spatter and small welding spots;
4: The demand for sample proofing capabilities, the trial production of conceptual new samples, the OEM production of small batch samples, and the development and testing of laser welding processes all require a laboratory with multiple sets of proofing machines and rich proofing experience.
High Productivity
1.Product type：Ф220mm，pin wire bare copper size 3.84*1.77mm，48 slots * 4 layers, a total of 192 welding spots, total cycle time：Taking photos + laser welding＜35s;
2.Scan areaФ230mm，neither the product nor the welding head needs to be moved;
3.Orientation developed vision system CHVis: Wide range of photos、High success rate、High accuracy;
4.High Power Laser Welding: welding a pin of the same specification to achieve the same welding effect, 6000w takes 0.11s, 8000w only takes 0.08s.
Rework at the same station
1.Spatters and small welding spots can be reworked using CHVis;
2.CHVis Visual Rework Function: Rework of bad welding spots or missing welding spot.
Welding spots intelligent processing
1.Deviation pin wire measurement before welding: CHVis vision system monitors the gap, left and right misalignment, angle, area and other states of the pins after clamping;
2.Intelligent processing of welding spots deviation. Automatically identify the welding spots deviation, and call the corresponding parameters for welding;
Position compensation function
Consistency of appearance of welding spots:
• The head deviation phenomenon caused by the oblique incidence of laser can be compensated by position；
• Can be compensated separately in radial and tangential direction；
• Compensation can also be performed independently for each welding spot
Quality Inspection after Welding
1.OK/NG welding spot scanning cloud image：detect failure types such as welding pit, sharp corners, welding spot deviations, and missing welding spots;Send failed welding spot locations to PLC and operator;
2.Height difference detection before welding.
Strong laboratory proofing ability
1.Multiple sets of motor proofing machine;
2.Vision Guide Proofing System;
3.High production capacity of single-day proofing.
Carman Haas orientation developed vision system CHVis.
Product: 48 slots x 4 layers, a total of 192 welding spots, take photos+welding: 34s
