Description

Technical Field

[0001] This utility model relates to the field of flat wire motor stator production technology, and in particular to a 2D high-speed molding machine. Background Technology

[0002] Flat wire motors typically consist of a stator, rotor, and reducer, with the stator being one of the core components. The stator is the stationary part of the motor, usually composed of coils wound with copper wire, and is fixed in place within the motor housing. Its main function is to generate a magnetic field, driving the rotor to rotate, thus completing the motor's operation.

[0003] The primary function of the stator in a flat-wire motor is to generate a magnetic field, which can be a constant direct current (DC) magnetic field or a changing alternating current (AC) magnetic field. When the current through the stator coils changes, a change in magnetic flux is generated in the conductor. This change in magnetic flux affects the shape of the magnetic field, which in turn determines the direction and speed of the rotor's rotation. The interaction between the magnetic field generated in the stator and the magnetic field in the rotor causes the rotor to rotate under the influence of torque.

[0004] In the production and processing of flat wire motor stators, wire forming equipment is needed to bend the straightened flat wires to the angle specified in the drawings. Currently, existing bending processes generally suffer from defects such as poor compatibility, low bending speed, poor bending accuracy, and low consistency. Furthermore, there is no real-time detection after bending, making it impossible to provide feedback on the deviation of the bending angle for angle compensation, thus failing to effectively guarantee the accuracy of the wire profile.

[0005] Therefore, how to achieve fast and high-precision flat wire bending is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The technical solution of this utility model is implemented as follows:

[0051] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0052] Example 1

[0053] In a specific embodiment 1, such as Figure 1-3As shown, a 2D high-speed molding machine includes a clamping unit 6, a clamping drive unit, a hollow rotating platform 4, a rotation drive unit, a cam follower 3, and a detection mechanism.

[0054] In this embodiment, the clamping unit 6 includes a first clamping piece 6-1 and a second clamping piece 6-2; the clamping drive unit is connected to at least one of the first clamping piece 6-1 and the second clamping piece 6-2.

[0055] In this embodiment, the hollow rotating platform 4 is at least partially disposed on the outside of the clamping unit 6 and can rotate relative to the clamping unit 6.

[0056] The rotary drive unit is connected to the hollow rotary platform 4; the cam follower 3 is fixed to the upper surface of the hollow rotary platform 4.

[0057] The clamping drive unit includes a connecting rod 7 and a miniature electric cylinder 8; one end of the connecting rod 7 is connected to the miniature electric cylinder 8, and the other end is connected to at least one of the first clamping plate 6-1 and the second clamping plate 6-2.

[0058] The rotary drive unit includes a servo drive motor 5.

[0059] The testing mechanism is located above the clip unit 6;

[0060] The testing agency uses it to check whether the flat wire is bent in place.

[0061] In this embodiment, the detection mechanism includes an industrial camera 9, a lens 10, a bowl light 11, and a strip light 12.

[0062] This embodiment can be used for bending flat wires of U pin1 or I pin2.

[0063] In this embodiment, during application, the miniature electric cylinder 8 drives the clamping unit 6 to fully grip the flat wire via the connecting rod 7, ensuring that the flat wire has the lowest degree of freedom during bending. If it is necessary to adjust the flat wire specifications, the parameters of the miniature electric cylinder 8 can be set in the control center, so that the distance by which the miniature cylinder pushes the clamping unit 6 to close will be appropriately changed, thereby adapting to different specifications of flat wire.

[0064] In this embodiment, the servo drive motor 5 directly drives the hollow rotating platform 4 to rotate relative to the clamping unit 6. The rotation of the rotating platform drives the cam follower 3 to rotate. When the two cam followers 3 rotate, they will bend the flat wire clamped by the clamping unit 6. By controlling the parameters of the servo motor to adjust the rotation angle of the hollow rotating platform 4, the degree of bending of the flat wire can be controlled, thereby achieving high-precision bending.

[0065] During the flat wire bending process, the industrial camera 9 detects the bending angle of the flat wire in real time and feeds the photos back to the control center. The control center processes the photos taken by the industrial camera 9, analyzes the actual bending angle of the flat wire, and calculates the difference between the actual bending angle and the ideal bending angle. Based on the difference, the control center calculates the compensation angle and feeds it back to the servo drive motor 5 to realize the real-time compensation angle of the bending servo motor, so as to maximize the consistency and high precision of bending.

[0066] To ensure accuracy during inspection, this embodiment employs dual supplementary lighting, including bowl light 11 and strip light 12, to make the industrial camera 9 capture images more clearly.

[0067] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
