As the core component of new energy vehicles, the drive motor has an important impact on the performance of new energy vehicles. Compared with round wire motors, flat wire motors have the advantages of small volume, material saving, high efficiency, etc., and currently have become the development trend of new energy motors. During the assembly process of flat wire motors, the flat wires need to be formed into the required shapes. Since the number of flat wire hairpin layers required for the stator of new energy vehicle drive motors is increasing (currently up to 12 layers), the requirements for the efficiency and types of flat wire forming are also increasing.

[0042] Embodiment

[0043] In a specific embodiment, as Figure 1 shown, a device for automatic feeding of a flat wire forming machine includes a storage mechanism 4, a transplanting mechanism 2, a positioning mechanism 3, and a base 1. The storage mechanism 4 and the positioning mechanism 3 are fixedly installed on the base 1, the base 1 is slidably connected to the transplanting mechanism 2, and the storage mechanism 4 is located above the transplanting mechanism 2.

[0044] In this embodiment, the storage mechanism 4 is used for the initial positioning and storage of the flat wire 100 during the forming process of the motor stator hairpin. The transplanting mechanism 2 is used for transplanting the flat wire 100 from the flat wire cartridge in the storage mechanism 4 to the forming position. The positioning mechanism 3 is used for the precise positioning before the flat wire 100 is formed. The base 1 is used for installing and fixing the storage mechanism 4, the transplanting mechanism 2, and the positioning mechanism 3. In this embodiment, in addition to storing a part of the flat wire 100 for feeding and forming, the storage mechanism 4 is also provided with a compatibility component and a support release component. The compatibility component is used to adjust the storage mechanism 4 so that it can be compatible with different specifications of the flat wire 100 and improve its adaptability. The support release component is used to support and control the release of the flat wire 100 during feeding. The installation positions of the compatibility component and the support release component are not fixed. According to different models of the flat wire forming machine, they can be set in various forms such as knobs and buttons that are convenient for manual operation. Through this design, combined with the transplanting of the transplanting mechanism 2 and the precise positioning of the positioning mechanism 3, the caching and batch feeding of the flat wire 100 can be realized, and different sizes of the flat wire 100 can be flexibly compatible. Since this embodiment integrates storage, transplanting, and positioning into a total device, the transplanting distance is short, the volume is small, the feeding speed is faster, the cost advantage is obvious, and it can be integrated into the interior of the forming machine.

[0045] In a preferred embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the base 1 includes a bottom plate 1-1, a support seat 1-2, a positioning table 1-3, a base guide rail 1-4, a transplanting cylinder 1-5, and a blocking block 1-6; the support seat 1-2 is fixed on the bottom plate 1-1, the number of the support seats 1-2 is 2, the positioning table 1-3 and the blocking block 1-6 are installed on the support seat 1-2, the transplanting cylinder 1-5 is installed on the left support seat 1-2, the positioning table 1-3 is connected to the storage mechanism 4, and the base guide rail 1-4 and the transplanting cylinder 1-5 are connected to the transplanting mechanism 2.

[0046] The base guide rail 1-4 and the transplanting cylinder 1-5 are floatingly connected to the transplanting mechanism 2.

[0047] The transplanting mechanism 2 includes a flat wire transplanting plate 2-1, a flat wire limiting block 2-2, a detection sensor 2-3, a flat wire lower support 2-4 and a flat wire upper limit 2-5; the flat wire transplanting plate 2-1 is arranged on the base guide rail 1-4 and connected to the transplanting cylinder 1-5, and the flat wire limiting block 2-2, the detection sensor 2-3, the flat wire lower support 2-4 and the flat wire upper limit 2-5 are arranged on the flat wire transplanting plate 2-1.

[0048] The positioning mechanism 3 includes a positioning mounting base 3-1, a positioning cylinder 3-2, a positioning mounting plate 3-3, a positioning shaft 3-4, a positioning shaft sleeve 3-5, a positioning spring 3-6 and an adjustment plate 3-7; the positioning mounting base 3-1 is arranged on the base 1, the positioning cylinder 3-2 is arranged on the positioning mounting base 3-1, the positioning mounting plate 3-3 is arranged on the positioning cylinder 3-2, and the positioning shaft 3-4, the positioning shaft sleeve 3-5, the positioning spring 3-6 and the adjustment plate 3-7 are installed on the positioning mounting plate 3-3.

[0049] The storage mechanism 4 includes a positioning seat 4-1, a mounting plate 4-2, a limiting plate 4-3 and a positioning pin sleeve 4-4; the positioning seat 4-1 is connected to the positioning table 1-3, and the mounting plate 4-2 and the limiting plate 4-3 are fixedly connected to the positioning seat 4-1.

[0050] The storage mechanism 4 further includes a positioning pin sleeve 4-4; the positioning pin sleeve 4-4 is arranged in the positioning seat 4-1, and the positioning seat 4-1 and the positioning table 1-3 are positioned and connected by a positioning pin.

[0051] This embodiment provides an example of a detailed structure of the base 1, the transplanting mechanism 2, the positioning mechanism 3 and the storage mechanism 4 that can be specifically implemented. However, in the actual production process, various components can be finely adjusted. For those skilled in the art, in order to match different models, adjusting different structures should be common sense. Therefore, adjusting various structures included in this embodiment without involving creative labor should also be within the scope of protection of the present invention.

[0052] In this embodiment, for the connection between the base guide rail 1-4 and the transplanting mechanism 2, and the connection between the transplanting cylinder 1-5 and the transplanting mechanism 2, the floating connection method is more convenient when feeding and forming the flat wire 100. The detection sensor 2-3 is used to detect the position of the flat wire 100.

[0053] First, the operator or the conveying mechanism transports the flat wire 100 into the storage mechanism 4. The operator connects the storage mechanism 4 filled with the flat wire 100 to the positioning table 1-3 of the base 1 through the positioning seat 4-1 for pin positioning, and the operator presses the start button of the equipment.

[0054] Then, the flat wire transplanting plate 2-1 is driven by the transplanting cylinder 1-5 to the flat wire loading station. The upper limit 2-5 of the flat wire on the transplanting mechanism 2 is compressed and avoided by the limit plate 4-3 of the storage mechanism 4, so that the flat wire limit groove of the flat wire transplanting plate 2-1 is opened. The bottom flat wire 100 in the storage mechanism 4 falls into the limit groove of the flat wire transplanting plate 2-1. The flat wire limit groove of the flat wire transplanting plate 2-1 is set to only allow one flat wire 100 to fall in. The flat wire 100 falling into the limit groove is supported by the lower flat wire support 2-4 installed at the lower part of the flat wire transplanting plate 2-1 to prevent the flat wire 100 from falling from the bottom of the flat wire limit groove. The detection sensor 2-3 installed on the flat wire transplanting plate 2-1 detects that the flat wire 100 has fallen into the flat wire limit groove. The transplanting cylinder 1-5 drives the flat wire transplanting plate 2-1 to move to the flat wire forming station. During the transplanting process, the upper limit 2-5 of the flat wire is released at the same time. When the flat wire 100 is transplanted by the flat wire transplanting plate 2-1 to the forming station, the blocking block 1-6 on the support seat 1-2 of the base 1 compresses the lower flat wire support 2-4 at the bottom of the flat wire transplanting plate 2-1, so that the bottom of the flat wire limit groove of the flat wire transplanting plate 2-1 is completely opened.

[0055] After that, after the transplanting cylinder 1-5 is in place, the detection sensor 2-3 gives a signal, and the positioning cylinder 3-2 of the positioning mechanism 3 extends, driving the positioning shaft 3-4 to push the flat wire 100 in the flat wire limit groove of the flat wire transplanting plate 2-1 through the compression force of the positioning spring 3-6 to perform precise positioning on the flat wire 100 to prevent damage to the flat wire. After the positioning is completed, the forming die of the forming machine forms the flat wire 100. After forming, the flat wire transplanting plate 2-1 is transplanted to the flat wire loading station, and the above actions are repeated to complete the next automatic loading of the flat wire.

[0056] It should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
