[0002] The motor stator is one of the important components of the motor. Among them, the stator is the stationary part of the motor, mainly composed of an iron core, a stator winding and a frame. The stator winding refers to the copper wire coil wound and installed on the stator. In the production process of the flat wire stator, it is necessary to bend the flat copper wire into a single coil to realize the installation of the flat copper wire coil into the slot. In the process of connecting the flat copper wire coil after being inserted into the slot according to the requirements of the winding wiring diagram, a wire turning machine is usually used. The wire turning machine can complete the function of turning the copper wire at the welding end of the flat wire stator winding connection, which is one of the important processes of the flat wire stator automatic production line. However, in the existing production, there is no pre-detection before entering the mold for the flat wire stator before entering the mold, resulting in the phenomenon that abnormal copper wires damage the wire turning mold, increasing the production cost and affecting the overall production and processing efficiency. Summary of the Utility Model

[0004] The above problems to be solved by the utility model are realized through the following technical solutions:
[0005] On the one hand, a flat wire motor stator detection mechanism with a pre-detection function before entering the mold is proposed, which includes a mounting substrate, a bracket for supporting the mounting substrate, a mounting base and a pre-detection jig before entering the mold.

A force measuring and weighing sensor is arranged between the sliding bottom plate and the mounting base, and its two end faces are respectively fixedly connected with the sliding bottom plate and the mounting base.

[0023] As Figures 1-3 shown, the present utility model provides a vertical turning machine for a flat wire motor stator detection mechanism with an in-mold pre-inspection function, which includes a bench 1, a frame 2 erected on the bench 1. A flat wire motor stator detection mechanism 3 with an in-mold pre-inspection function, an automatic conveying mechanism 4, a handling mechanism 5 and a turning mechanism 6 are fixedly arranged on the frame 2. An insert protection mechanism 7 is arranged at the position of the turning mechanism 6 on the frame 2.
[0024] A controller for controlling the operation of the detection mechanism 3, the automatic conveying mechanism 4, the handling mechanism 5 and the turning mechanism 6 is arranged on the frame 2. The automatic conveying mechanism 4 is used for conveying a tray loaded with a flat wire motor stator. The handling mechanism 5 is used for handling the flat wire motor stator to move the flat wire motor stator on the tray to the detection mechanism 3 and the insert protection mechanism 7 or move the unqualified flat wire motor stator back to the tray.
[0025] In this embodiment, referring to Figures 2-3 shown, the flat wire motor stator detection mechanism 3 with an in-mold pre-inspection function includes a mounting substrate 301, a bracket 302 for supporting the mounting substrate 301, a mounting base 303 and an in-mold inspection tool 304. A slide rail 305 is arranged on the upper surface of the mounting substrate 301 along its length direction, and a slider 306 is arranged on the slide rail 305. A sliding bottom plate 307 is fixedly arranged on the slider 306. At least two slide rails 305 are arranged and symmetrically arranged on the upper surface of the mounting substrate 301. At least three sliders 306 fixedly connected to the sliding bottom plate 307 are arranged on each slide rail 305 to improve the smoothness of the sliding bottom plate 307 during movement. A sliding support 308 is arranged on the sliding bottom plate 307, and the sliding support 308 is fixedly connected to the mounting base 303 to lift the mounting base 303.
[0026] The in-mold inspection tool 304 is fixedly arranged on the mounting base 303, and a pre-inspection cavity for detecting the flat wire motor stator is arranged inside it. A force measuring and weighing sensor 309 is arranged between the sliding bottom plate 307 and the mounting base 303, and its two end faces are respectively fixedly connected to the sliding bottom plate 307 and the mounting base 303. Through holes are coaxially arranged at the positions of the in-mold inspection tool 304 and the mounting base 303 opposite to the force measuring and weighing sensor 309.
[0027] Furthermore, the in-mold inspection tool 304 is assembled on the upper end face of the mounting base 303 by bolts. The in-mold inspection tool 304 is provided with a cut surface along the edge of the mounting base 303, so that the in-mold inspection tool 304 is flush with the outer surface of the mounting base 303, avoiding interference at the processing position caused by the part of the in-mold inspection tool 304 protruding from the mounting base 303.
[0028] A fixed seat 310 is provided outside the mounting substrate 301. A cylinder 311 is provided on the fixed seat 310. The movable shaft of the cylinder 311 is fixedly connected to a connection block 312 provided on the sliding bottom plate 307, so that the mounting base 303 drives the in-mold fixture 304 to move under the drive of the cylinder 311. Oil pressure buffers 313 are respectively provided at both ends of the mounting substrate 301 in the length direction. This structure plays a buffering role when the sliding bottom plate 307 moves to both ends.
[0029] During operation, the flat wire motor stator to be detected is loaded on the tray. The automatic transfer mechanism 4 transports the tray to the loading position of the handling mechanism 5, and the RFID reads the code of the tray. Then, the handling mechanism 5 transports the flat wire motor stator to be detected on the automatic transfer mechanism 4 into the in-mold fixture 304, and makes part of the flat wire motor stator coincide with the pre-inspection cavity. At the same time, the part of the flat wire motor stator coil passing through the through hole contacts the force measuring and weighing sensor 309. The force measuring and weighing sensor 309 detects the change in the in-mold thrust of the flat wire motor stator coil placed in the in-mold fixture 304. When the flat wire motor stator in the in-mold fixture 304 is unqualified, the handling mechanism 5 transports the flat wire motor stator back to the tray and marks it as unqualified. When the flat wire motor stator in the in-mold fixture 304 is qualified, the handling mechanism 5 transports the flat wire motor stator to the insert protection mechanism 7. At the same time, the insert protection mechanism 7 extends to protect the copper wires and insulating paper at the front and rear ends of the flat wire motor stator, and the hairpin protective cover extends to prevent the hairpin wire and IPIN wire from moving. Then, the insert protection mechanism 7 and the flat wire motor stator descend to the twisting mechanism 6 together. The 8-axis independent twisting die provided by the twisting mechanism 6 completes the automatic twisting, following, and springback actions of 1 to 8 layers of copper wires in batches. Finally, the handling mechanism 5 transports the qualified processed flat wire motor stator to the tray. Through the above structure, the in-mold detection before the twisting and in-mold of the flat wire motor stator can be automatically completed by the mechanical fixture, and the flat wire motor stator with unqualified in-mold can be automatically excluded to protect the twisting die and avoid damage to the twisting die caused by abnormal copper wires.

Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
