[0002] In the assembly process of mechanical components, especially when it comes to transmission structures with needle-shaped shafts, steps such as needle feeding, needle insertion and assembly are usually required. These operations are crucial to ensure the stability and reliability of the transmission structure.
[0003] Although some automated pin insertion and feeding mechanisms have been developed in the prior art, if the pin insertion assembly leaks needles during the pin insertion process, material needles will remain inside the needle feeding assembly, causing the feeding assembly to overlap needles when the needle feeding assembly takes the needles again, resulting in the pin insertion and feeding mechanism being unable to perform the pin insertion action on the device next time. Summary of the invention
[0004] The purpose of the utility model is to solve the problem that although some automated pin insertion and feeding mechanisms have been developed in the prior art, if the pin insertion assembly leaks needles during the pin insertion process, material needles will remain inside the needle feeding assembly, resulting in overlapping needles when the needle feeding assembly takes needles again, causing the pin insertion and feeding mechanism to be unable to insert needles on the device next time. A precise feeding mechanism for an automatic pin insertion machine is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A precise feeding mechanism of an automatic needle insertion machine comprises a bottom support plate, a bottom circular array of bottom support plates has bottom support feet, a feeding plate is rotatably connected to the top of the bottom support plate, a transfer cavity is formed in a circular array on the top of the feeding plate, holes are formed in a circular array at the bottom of the transfer cavity, a servo motor is arranged at the center of the rotating shaft of the feeding plate, a needle drop hole and a recovery hole are sequentially opened on the top of the feeding plate, a side surface of the bottom support plate is fixedly connected to the bottom of a first U-frame, a needle storage plate is fixedly arranged on the top of the side surface of the first U-frame, a needle feeding assembly for feeding material needles into the device is arranged on the top of the recovery hole, a bottom connecting frame is fixedly arranged on the bottom of the side surface of the bottom support plate, and a safety assembly for preventing material needles from remaining in the transfer cavity is arranged on the side surface of the bottom connecting frame.
[0007] Optionally, the needle feeding assembly includes a needle feeding box, a second U-frame, a mounting seat, and an adjustment seat. The side of the needle feeding box is fixedly connected to one end of the side of the second U-frame, and the bottom of the side of the second U-frame is fixedly set on the side of the bottom support plate.
[0008] Optionally, a mounting seat is fixedly provided at the bottom of the bottom support plate below the needle drop hole, an adjusting screw is screwed into the mounting seat along the vertical direction, and an adjusting seat is fixedly provided on the top of the adjusting screw.
[0009] Optionally, the safety component includes a connection block, a recovery box, and a U-shaped handle, and the connection block is movably inserted into the side surface of the bottom frame along the horizontal direction.

[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. The utility model is provided with a support plate and a feed plate, and a safety component is provided on the feed plate. The safety component can recover the material needles that may remain in the feed structure from the transfer chamber after the needle feeding structure completes the needle feeding work, which can effectively solve some traditional automated pin insertion and feeding mechanisms. However, if the pin insertion component leaks needles during the pin insertion process, material needles will remain inside the needle feeding component, resulting in the phenomenon of overlapping needles in the feed component when the needle feeding component takes the needle again, resulting in the pin insertion and feeding mechanism being unable to perform the pin insertion action on the device next time.
