Description

Technical Field

[0002] When manufacturing a motor, the motor casing is the outer protective structure of the motor, usually made of metal or high-strength plastic. Its main function is to enclose and protect the internal components (such as the stator, rotor, windings, etc.), while also assuming functions such as heat dissipation, mechanical support, and environmental protection.

[0003] The housing and connector need to be manufactured and press-fitted, and combined with the corresponding rotor, stator and bearings. There cannot be large errors during the combination. If there are large errors, the motor will not work properly. In the process of motor housing processing, automated mechanized automatic processing is required. At the same time, it is necessary to monitor whether the combination between components in each link is standard. The procedure is cumbersome. If it is manually inspected or paused, the efficiency of automated processing will be reduced. Summary of the Invention

[0035] Reference Attachment Figure 1 , is a flow chart of a method for pre-processing a motor housing in an embodiment of the present application; Example 1

[0036] A motor casing pre-processing method, the method comprising:

[0037] Obtain the housing, connector and PCB, and process the housing, connector and PCB separately;

[0038] Manipulator collaboration includes but is not limited to cylinders, motors, and belts for transporting materials;

[0039] Determine the processing flow position of the housing, connector and PCB by scanning the code;

[0040] Defective products are detected and sent out from the defective belt.

[0041] In this embodiment, in the step of obtaining the housing, the connector and the PCB, and processing the housing, the connector and the PCB separately,

[0042] The robot grabs the casing, codes it, vacuums it with vibration, scans the code for confirmation, and applies glue to the inner wall of the casing in a circular manner;

[0043] Connector feeding sensing, marking, detection of marking, photoelectric sensing position, plasma cleaning;

[0044] The PCB is placed in the holder for pin detection, code scanning, and front and back inspection.

[0045] After the steps of the robot grabbing the casing to code, vibrating to remove dust, scanning the code to confirm, and applying glue to the inner wall of the casing in a circular manner,

[0046] The housing is placed on a press for expansion and installation and plasma cleaning.

[0047] In another embodiment, after the PCB is placed in the seat and undergoes the steps of pin detection, code scanning, and front and back detection,

[0048] Place the PCB on the lower die of the press, place the connector on the upper die of the press, and then press the PCB and connector together using the press.

[0049] Specifically, after the PCB completes the fully automatic inspection process in the placement seat (including high-precision pin on / off detection, QR code identity information scanning and machine vision front and back recognition), the system uses a vacuum adsorption robot to accurately transfer the qualified PCB to the lower mold station of the press, and achieves a positioning accuracy of ±0.05mm based on pressure feedback and laser positioning technology. At the same time, the connector that has been plasma cleaned and activated is grabbed by the robot, and the 3D vision guidance is used to match the upper mold fixture of the press to complete the secondary orientation calibration and posture fine-tuning. A closed-loop control system is used in the pressing stage to dynamically optimize the pressing by real-time monitoring of the pressure curve (adjustable from 0 to 50kN), temperature compensation module (20-80℃ temperature control) and displacement sensor (accuracy of ±2μm). Parameters are set to ensure that the PCB gold fingers and connector contacts are precisely fitted without stress. After pressing, online electrical performance tests (such as impedance detection and continuity test) are immediately triggered, and the temperature distribution of the joint surface is monitored simultaneously through infrared thermal imaging. Abnormal data automatically triggers the MES system alarm and marks the NG batch. Good products are transferred to the next assembly link through the circular assembly line, while NG products are switched through the electromagnetic sorting valve and discharged through the anti-static defective product belt line. The entire process data (including pressing force curve, detection waveform, and process image) is encrypted and stored in the cloud, supporting reverse traceability of process parameters and SPC statistical analysis. The integrated pressing system realizes the intelligent assembly closed loop of the three core components of the chassis, connector, and PCB through multi-sensor fusion and adaptive control algorithm.

[0050] In another embodiment, after the steps of placing the PCB on the lower die of the press, placing the connector on the upper die of the press, and then pressing the PCB and the connector together through the press,

[0051] Place the housing on top of the press machine, place the PCB and connector combination on the bottom of the press machine, and press-fit the housing, PCB and connector together.

[0052] Specifically, after the PCB and connector are precisely pressed together, the system uses a multi-axis collaborative robot to grab the housing that has been plasma cleaned and pre-installed with a sleeve, and uses 3D visual positioning and force feedback composite guidance technology to hover the housing above the press with a repeatability accuracy of ±0.02mm. At the same time, the adaptive fixture at the lower station fixes the PCB-connector assembly through vacuum adsorption and electromagnetic locking, and starts laser grid projection for three-dimensional coplanarity calibration. The press-fitting process uses gradient pressure control (0-200kN programmable), combined with infrared thermal imaging to monitor component deformation in real time. The servo press dynamically compensates for the extrusion of the annular adhesive layer on the inner wall of the casing (adhesive thickness control accuracy is ±5μm) to ensure uniform stress distribution on the three interfaces. After the pressing is completed, a four-dimensional quality inspection system is triggered: 1) Airtightness test (0-50kPa pressure difference cycle detection) verifies the assembly sealing; 2) Laser displacement sensor scans the component contour and compares it with the CAD model (tolerance band ±0.1mm); 3) High-frequency impedance analyzer detects the impedance of the connector-PCB-casing ground loop (threshold ≤5mΩ); 4) Industrial endoscope AI vision system detects the continuity of the inner wall glue line. All inspection data are verified through OPC The UA protocol is synchronized to the MES system to generate an assembly digital twin. Qualified products are transferred to the aging test station via AGV linkage, while NG products are separated from the production line by a pneumatic lifting mechanism and enter the fault analysis station through an anti-static isolation channel. Their failure mode data automatically triggers the SPC system to update the process parameter library. This hierarchical assembly system achieves millisecond-level dynamic optimization of process parameters through embedded edge computing. Combined with the unique laser QR code of each component (including material batch, processing timestamp and process version), it builds a full life cycle quality traceability chain, and ultimately achieves zero-defect control of mechanical-electrical-adhesive integrated assembly.

[0053] In this embodiment, after the steps of placing the housing on top of the press machine, placing the PCB and connector assembly on the bottom of the press machine, and press-fitting the housing, PCB, and connector,

[0054] After the casing, PCB and connector are pressed together, the finished product is coated with glue for a certain temperature protection after the curing furnace and cooling furnace, and then the connector and the casing are welded to each other by scanning the code.

[0055] In this embodiment, in the step of determining the processing position of the housing, connector and PCB by scanning the code,

[0056] Including but not limited to casing glue coating inspection, connector marking inspection, plasma cleaning photoelectric sensing position detection, connector detection for jacks, code scanning, PCB pin detection for both sides, connector glue coating camera inspection, connector welding station inspection, and camera detection of welding points.

[0057] After inspection, any defective products are removed from the defective belt.

[0058] Specifically, in the above-mentioned multiple inspection processes, all defects that may affect the subsequent motor assembly function due to errors that are easy to occur during processing are avoided, and the defective belts will be sent to be reworked or scrapped, thereby improving the efficiency of reprocessing defective products and the overall process recycling processing.
