Description

Technical Field

[0001] The present invention relates to the technical field of automated detection in motor production, and particularly to a special auxiliary machine for automatically detecting the electrical performance of a flat wire stator. Background Art

[0002] In the field of motor production, the electrical performance detection of flat wire stators is a key link to ensure product quality. However, the traditional detection process has significant defects due to relying on manual operations: operators need to manually complete repetitive tasks such as scanning codes, clamping, and data binding, resulting in low efficiency. The manual operation speed is limited by physical fatigue and is difficult to meet the requirements of large-scale production. At the same time, during the manual clamping process, direct contact with the stator and the electrical parts of the detection equipment is required. If the equipment insulation fails or there are operational errors (such as wet hands), it is easy to cause electric shock accidents and there are safety hazards. In addition, the detection accuracy depends on regular manual spot checks and calibration, and it is easy to cause equipment deviations due to personnel negligence or missed spot checks, which in turn affects the accuracy of detection data and increases the defective product rate, highlighting the quality control defects.

[0003] In the prior art, although some equipment has introduced functions such as code scanning or clamping, the overall process still lacks an integrated fully automated solution. For example, links such as stator positioning, data binding, clamping detection, and isolation of defective products still require segmented operations, resulting in poor equipment coordination and frequent process interruptions. In addition, the existing clamping mechanism lacks the ability of adaptive adjustment, and it is easy to cause stator damage or poor contact due to uneven clamping force, further affecting the detection reliability.

[0004] The above problems indicate that there is an urgent need for a special auxiliary machine for automatically detecting the electrical performance of a flat wire stator to break through the efficiency bottleneck of traditional technologies and eliminate the risks brought by manual intervention.

[0050] Specifically, the bottom of the non-conforming isolation cart 10 is equipped with universal wheels and fixedly installs the non-conforming standard sample placement plate 13, realizing the rapid transfer and classified storage of non-conforming stators, and at the same time supporting the flexible movement of the isolation cart to the designated area, facilitating subsequent repair or re-inspection operations.

[0051] Embodiment IV In order to achieve high-precision calibration and standardized management of the equipment, as Figure 2 andFigure 3 As shown in Figure 3 , in this embodiment, a special machine for automatically detecting the electrical performance of a flat wire stator includes: Furthermore, the electrical performance ground wire connection mechanism 2 includes a telescopic conductive contact, and the telescopic conductive contact contacts the ground wire terminal of the stator assembly 5 through a spring reset mechanism.

[0052] Specifically, the electrical performance ground wire connection mechanism 2 adopts a telescopic conductive contact and a spring reset mechanism, realizing the adaptive adjustment of the contact pressure of the ground wire terminal. Even when there is a height tolerance in the stator ground wire terminal, it can still ensure reliable contact of the conductive contact and form a stable detection circuit.

[0053] Furthermore, the stator buffer station plate 11 has the same size as the OK standard sample placement plate 8, the NG standard sample placement plate 9, and the unqualified standard sample placement plate 13.

[0054] Specifically, the stator buffer station plate 11, the OK standard sample placement plate 8, the NG standard sample placement plate 9, and the unqualified standard sample placement plate 13 adopt the same size, realizing the standardized design of the tooling plate, simplifying the grasping logic of the manipulator and the process of station switching, and reducing the equipment complexity.

[0055] Furthermore, the control system includes a power-on automatic calibration module for calibrating the equipment through the detection data of the OK standard sample and the NG standard sample.

[0056] Specifically, the control system integrates a power-on automatic calibration module. By calling the detection data of the OK standard sample and the NG standard sample, it realizes the real-time calibration of the equipment parameters and deviation warning, ensures the long-term stability of the detection accuracy, and reduces the frequency of manual calibration and the risk of misoperation.

[0057] When the present invention is in use, after starting the equipment, the control system executes a self-check program to confirm that the states of all mechanisms are normal. Through the power-on automatic calibration module, the equipment is calibrated using the standard samples placed on the OK standard sample placement plate 8 and the NG standard sample placement plate 9. The system compares the detection data of the standard samples and adjusts the parameters to ensure the detection accuracy.

[0058] The stator assembly 5 is moved to the detection station along with the assembly line tooling plate 4 by the assembly line body 12. The lifting and rotary indexing mechanism 3 lifts the assembly line tooling plate 4 and the stator assembly 5 to a preset detection height and rotates to a specified angle to ensure that the stator is in the best detection posture.

[0059] The barcode scanner 6 scans the identifier of the stator assembly 5 and binds the scanned data with the subsequent detection results to realize product traceability. According to the position of the stator, the barcode scanner 6 automatically aligns with the identifier through the adjustable angle module to ensure the scanning accuracy.

[0060] The automatic clamping mechanism 1 for the three-phase electric wire precisely clamps the three-phase electric wires of the stator assembly 5 through the jaws with an insulating layer on the surface, ensuring reliable contact and no short-circuit risk. The retractable conductive contact of the grounding wire connection mechanism 2 for electric performance automatically contacts the grounding terminal of the stator under the action of the spring reset mechanism, forming a complete detection circuit.

[0061] The control system sends instructions to perform the detection of electric performance parameters. The system compares the detected data with the reference value of the standard sample to determine whether the stator is qualified. If the data is abnormal, an alarm is triggered and it is marked as a non-conforming product.

[0062] The qualified stator assembly 5 continues to be transported to the next process along with the assembly line tooling plate 4. If the detection is unqualified, the stator moving manipulator 7 grabs the stator assembly 5 from the assembly line tooling plate 4 and transfers it to the non-conforming sample placement plate 13 of the non-conforming isolation cart 10, and at the same time, the equipment gives an audible and visual alarm.

[0063] During the detection interval or shift change, the equipment automatically calls the OK sample and the NG sample, grabs the sample to the detection station through the stator moving manipulator 7, and performs the spot-check process to ensure the long-term stability of the equipment. If a deviation is found during the spot-check, the system pauses operation and prompts for maintenance to avoid batch detection errors.

[0064] The stator buffer station plate 11 is used to temporarily store the stators to be detected or already detected, and cooperates with the stator moving manipulator 7 to achieve seamless connection between processes and avoid congestion on the assembly line.
