Flat wire stator windings are an important component of flat wire motors. The production of flat wire stator windings currently requires

[0003] Inserting wires, flaring, twisting, cutting, and welding. The insertion process is completed by a wire insertion machine, which inserts the formed flat wire terminals into the stator. At present, the feeding device used to convey the flat wire terminals in the wire insertion machine has a complex structure and needs to pass through at least two slide rods before it can be picked up. Such a structure is complex and inefficient. Utility Model Content

[0033] The embodiment of the present application provides a wire insertion feeding device for a flat wire motor stator, which is used to feed a wire insertion machine such as Figure 1 The flat wire terminal 10 is generally in an inverted U shape, and includes a kinked portion 11 in the middle and vertical portions 12 extending downward from both ends of the kinked portion 11 .

[0034] Reference Figure 2 The wire loading device includes a loading rail 20 which is arranged obliquely and on which the flat wire terminal 10 is mounted, a vibrating part (not shown in the figure) which drives the loading rail 20 to vibrate so that the flat wire terminal 10 moves on the loading rail 20, a push rod 30 which is arranged at the lower end of the loading rail 20 and is used to support the kinked part 11 of the flat wire terminal 10, a driving component 40 which drives the push rod 30 to move up and down, and two clamping components 50 which are arranged on both sides of the push rod 30 and can relatively open / clamp the vertical part 12 of the flat wire terminal 10. After a plurality of flat wire terminals 10 are placed on the inclined feeding track 20, they gradually move from the high end to the low end under the action of the vibration part, and reach the top rod 30 at the low end, and the driving component 40 drives the top rod 30 to move upward, and the two clamping components 50 respectively clamp the vertical part 12 of the flat wire terminal 10 to keep it in a vertical state. At this time, the top rod 30 supporting the kink part 11 moves downward and exits, and the external picking device picks up the flat wire terminal 10, and the two clamping components 50 are released. The picking device picks up the flat wire terminal 10 and inserts it into the stator of the flat wire motor, thereby completing the insertion of the stator of the flat wire motor. The above structure is adopted in the embodiment of the present application. After being transported by the feeding track 20, only one step of lifting action and clamping action is required to complete the preparation action before picking up. Not only is the structure simple, but also the efficiency of plugging in is greatly improved.

[0035] Specifically, refer to Figure 2 , Figure 3, a bracket 60 is provided at the lower end of the feeding track 20, and the driving assembly 40 is arranged on the bracket 60. The driving assembly 40 includes a vertically arranged cylinder (not shown in the figure) and an ejector bracket 42 connected to the piston 41 of the cylinder, and the ejector rod 30 is fixed on the ejector bracket 42. In this embodiment, the ejector bracket 42 is located on one side of the ejector rod 30, and the two are fixed in parallel, and the cylinder is arranged at the bottom of the ejector bracket 42. When the vertical stroke of the ejector rod 30 is constant, this structure can reduce the layout height in the vertical direction and make the layout of the components more compact.

[0036] Reference Figure 4 The top of the push rod 30 has two blocks 31, and a space is formed between the two blocks 31 to support the kinked portion 11 of the flat wire terminal 10. The block 31 close to the feeding track 20 is relatively low, which, on the one hand, limits the flat wire terminal 10 located on the push rod 30, and on the other hand, blocks the next flat wire terminal 10, preventing the next flat wire terminal 10 from overlapping with the previous flat wire terminal 10 and entering the push rod 30.

[0037] Reference Figure 3 and Figure 5 In this embodiment, the clamping assembly 50 includes a first clamping block 51 and a second clamping block 52 which are arranged horizontally opposite to each other. The first clamping block 51 is fixedly connected to a first slider 53, and the second clamping block 52 is fixedly connected to a second slider 54. The first slider 53 and the second slider 54 are both slidably arranged on a slide rail 55. The first slider 53 and the second slider 54 are driven to move by two driving parts (not shown in the figure). The two clamping assemblies 50 are respectively fixed on the bracket 60 and are located on both sides of the top rod 30. Since the top rod 30 is supported on the kink portion 11 in the middle of the flat wire terminal 10, and the clamping assembly 50 is clamped on the vertical portion 12 of the flat wire terminal 10, the top rod 30 will not interfere with the clamping assembly 50 when moving upward.

[0038] In this embodiment, the clamping surface of the first clamping block 51 is engaged with the clamping surface of the second clamping block 52, and the engagement between the first clamping block 51 and the second clamping block 52 accommodates the accommodation space 56 of the vertical portion 12 of the flat wire terminal 10. The clamping surface of the first clamping block 51 and the clamping surface of the second clamping block 52 are both irregular surfaces, that is, non-planar surfaces, so that the two are better engaged when clamped, and the vertical portion 12 of the flat wire terminal 10 can be better clamped to prevent the flat wire terminal 10 from shaking.

[0039] Reference Figure 6A pressure rod 21 for pressing against the kinked portion 11 of the flat wire terminal 10 is provided at the top of the lower end of the feeding track 20, and the pressure rod 21 is arranged along the length direction of the feeding track 20. When the flat wire terminal 10 moves with the vibration of the feeding track 20, it may jump upward, and the pressure rod 21 plays a pressing role on the top of the flat wire terminal 10 to prevent the flat wire terminal 10 from jumping upward and causing the front and rear flat wire terminals 10 to overlap.

[0040] In this embodiment, the loading rail 20 is supported by two support rods 22, and the two support rods 22 are arranged on a tilting device 23. The tilting device 23 can adjust its tilting angle, so as to adjust the tilting angle of the loading rail 20. A buffer rubber block 24 is arranged between the two support rods 22 and the loading rail 20, that is, a soft connection between the support rods 22 and the loading rail 20 is realized, so as to avoid transmitting the vibration of the loading rail 20 to the support rods 22 and causing unstable support.

[0041] In this embodiment, the vibrating part (not shown in the figure) is an air pump, which is used to charge and discharge air to the upper material track 20 to drive the upper material track 20 to vibrate. The air nozzle 25 connected to the air pump is fixed on the buffer rubber block 24.

[0042] In this embodiment, an infrared transmitter 26 is provided at the upper end of the feeding track 20, and an infrared receiver 27 is provided at the bottom of the feeding track 20 to receive the signal of the infrared transmitter 26. The infrared transmitter 26 and the infrared receiver 27 can detect whether there is a flat wire terminal 10 on the feeding track 20, thereby reminding the staff to deliver the material in time.

[0043] The embodiment of the present application also discloses an automatic wire insertion machine for a flat wire motor stator (not shown in the figure), including a frame, a wire insertion loading device arranged on the frame, a picking device for picking up the flat wire terminal 10 from the loading device, and a wire insertion device arranged on the frame, wherein the wire insertion loading device is the above-mentioned wire insertion loading device.

[0044] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
