[0045] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] The following is combined with Figure 1-8The rotary clamping head 200 of the automatic detection device for the coil resistance of a coreless motor according to the present invention will be further described.

[0047] Please focus on Figure 1-3 and Figure 7-8 The utility model discloses a rotary clamping head 200 for an automatic detection device for the coil resistance of a coreless motor, comprising: a detection platform mounting plate 4, an insulation detection rod 3, an electric detection rotating assembly 1 fixedly connected to the lower part of the insulation detection rod 3 and used to drive the insulation detection rod 3 to rotate, and an openable and closable clamp 2 installed on the side of the electric detection rotation, the electric detection rotating assembly 1 passes through the detection platform mounting plate 4 in the up and down directions, and the electric detection rotating assembly 1 is installed on the detection platform mounting plate 4, the insulation detection rod 3 is located above the detection platform mounting plate 4, the openable and closable clamp 2 is also arranged around the outside of the insulation detection rod 3, and the openable and closable clamp 2 is a normally closed structure, the rotary clamping head 200 for the automatic detection device for the coil resistance of a coreless motor further comprises a jaw opening drive unit 5 for driving the openable and closable clamp 2 to open; the jaw opening drive unit 5 is installed on the detection platform mounting plate 4.

[0048] In this embodiment, all components are centrally mounted on the detection platform mounting plate 4, so that the present invention forms an integrated and stable structure.

[0049] The insulation test rod 3 is made of insulating material and is used to support the workpiece (motor coil 100) whose resistance is to be tested. The motor coil 100 consists of a generally annular coil body 00 and two wire ends 01 located at the same end of the coil body 00. Each resistance test requires connecting two test probes 300 to each wire end 01. The outer diameter of the portion of the insulation test rod 3 (the lower section of the insulation test rod 3) that contacts the coil body 00 matches the inner diameter of the coil body 00. When the retractable clamp 2 is closed, the insulation test rod 3 provides abutment for the clamp 2, preventing it from crushing the coil body 00. Furthermore, the upper section of the insulation test rod 3 provides abutment for the test probes 300, ensuring effective electrical connection when the test probes 300 extend and press against the wire end 01, facilitating accurate resistance measurements.

[0050] The electric inspection rotating assembly 1 is used to provide rotational power to adjust the angle of the motor coil 100 mounted on the insulation detection rod 3. The electric inspection rotating assembly 1 can have various structures, such as a stepper motor or a combination of a stepper motor and a reducer. When the electric inspection rotating assembly 1 rotates, the insulation detection rod 3 carries the motor coil 100 and rotates as a whole to adjust the position of the wire end 01, ultimately positioning the wire end 01 opposite the detection probe 300. When the motor coil 100 rotates to the appropriate position, the wire end 01 is positioned opposite the detection probe 300. When the detection probe 300 is extended, it can just press the wire end 01. The detection probe 300 is connected to a resistance detection device, and the resistance between the corresponding wire ends 01 can be measured.

[0051] The openable and closable clamp 2 can be opened and closed. The main innovation of this embodiment is that the openable and closable clamp 2 is set to a normally closed structure, and the openable and closable clamp 2 and the jaw opening drive unit 5 are respectively installed on different components. With this structure, the jaw opening drive unit 5 is fixedly installed on the detection platform mounting plate 4, and the pipeline of the jaw opening drive unit 5 is also fixedly installed. The pipeline will not rotate with the openable and closable clamp 2. The openable and closable clamp 2 can rotate freely following the electric inspection rotating sleeve 15, and because the openable and closable clamp 2 is a normally closed structure, when the openable and closable clamp 2 rotates following the electric inspection rotating sleeve 15, it can clamp the motor coil 100, ensuring that the motor coil 100 and the electric inspection rotating sleeve 15 rotate synchronously, meeting the use requirements. When it is necessary to open the openable and closable clamp 2, the openable and closable clamp 2 is rotated to the top of the jaw opening drive unit 5, and the jaw opening drive unit 5 is actuated, which can drive the openable and closable clamp 2 to open, and the motor coil 100 can be freely taken out.

[0052] Figure 7The present invention is a device for automatically testing the resistance of coreless motor coils, of which the present invention is a part. The following describes the use of the present invention in detail. First, the jaw opening drive unit 5 drives the retractable clamp 2 to open, placing the retractable clamp 2 in the open position. Then, using a human or robotic gripper, the motor coil 100 is placed onto the insulation test rod 3, ensuring that the wire end 01 faces upward. Because the retractable clamp 2 is a normally closed structure, removing the force exerted by the jaw opening drive unit 5 on the retractable clamp 2 returns the retractable clamp 2 to the closed position, clamping the motor coil 100 onto the insulation test rod 3. The electrical inspection rotating assembly 1 drives the insulation test rod 3, the retractable clamp 2, and the motor coil 100 to rotate as a whole, stopping when the wire end 01 faces the inspection probe 300. Driven by the external force, the inspection probe 300 extends and presses against the wire end 01, connecting the resistance detection channel. The resistance detection device connected to the inspection probe 300 can measure and display the resistance value, completing the purpose of testing the resistance value of the motor coil 100. After completing a measurement, the test probes 300 are retracted. The electrical inspection rotary assembly 1 then drives the insulation inspection rod 3, the retractable clamp 2, and the motor coil 100 to rotate a certain angle, so that the two test probes 300 are aligned with the two wire ends 01, and one test probe 300 is aligned with at least one new wire end 01 (untested). Driven by an external force, the test probes 300 extend and press against the wire end 01, completing another resistance measurement. Repeating this operation can obtain the resistance values ​​between different wire ends 01 to determine whether the motor coil 100 is qualified.

[0053] In summary, the present invention can clamp the motor coil 100 and rotate it to a preset angle without squashing the motor coil 100 during the clamping process. Specifically, the present invention supports the inner side of the motor coil 100 through the insulation detection rod 3, which can prevent the motor coil 100 from deforming during detection. The electric detection rotating assembly 1 is used to automatically rotate the motor coil 100 to a position where the wire end 01 is aligned with the detection probe 300, thereby achieving alignment with the detection probe 300. This facilitates the detection probe 300 to press the wire end 01 under the action of the automatic telescopic power, thereby automatically and quickly measuring the resistance value of the motor coil 100, greatly improving the detection efficiency and detection accuracy.

It is used to smoothly transmit the rotational power of the electric inspection rotating motor 11 to the electric inspection rotating shaft sleeve 15, and finally drive the insulation detection rod 3 to rotate to adjust the angle of the motor coil 100 sleeved on the insulation detection rod 3.

[0057] In this embodiment, the rotating motor mounting plate 12 and the rotating motor connecting column 13 together form a frame structure to ensure that the electric inspection rotating motor 11 is firmly installed.

[0058] The structure of the test rod receiving slot 151 and the side locking hole 152 facilitates quick installation and replacement of the insulation test rod 3. During installation, the lower portion of the insulation test rod 3 is inserted into the test rod receiving slot 151 and the locking screw is tightened to lock the insulation test rod 3. The reverse operation can be used to quickly remove the insulation test rod 3. The bearing 17 is used to improve the smooth rotation between the electric test rotating bearing seat 14 and the electric test rotating shaft sleeve 15.
