Description

An automatic nail feeding device for an automobile production line Technical Field

[0001] This utility model relates to the field of automobile production equipment technology, and in particular to an automatic nail feeding device for automobile production lines. Background Technology

[0002] Currently, automotive production lines operate at a fast pace, and manual screw feeding is insufficient to meet the required cycle time. Therefore, automated screw feeding devices are widely adopted to achieve continuous screw supply, shorten assembly cycles, and adapt to high-volume demands. This is especially true in scenarios involving multiple processes in engine and body manufacturing that require a large number of screws; automated screw feeding can significantly improve overall workflow efficiency. Traditional stepped screw feeders, as a type of automated screw feeding device, achieve orderly feeding through staggered movable and fixed steps. The fixed steps are fixed inside the frame or hopper, providing support tracks for screw sliding, while the movable steps are driven by cylinders or motors to push the screws. However, existing stepped screw feeders have fixed-length movable and fixed steps, which cannot accommodate screws of different lengths. Long screws are prone to jamming at the steps due to insufficient space, while short screws may tip over or slide off the tracks due to track redundancy, leading to feeding interruptions and significantly reducing screw feeding efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic nail feeding device for automobile production lines.

[0004] The technical solution of this utility model is as follows: An automatic nail feeding device for an automobile production line, comprising a stepped nail feeder and multiple staggered movable and fixed stepped plates arranged within the stepped nail feeder, further comprising: a feeding bin opened within the stepped nail feeder, wherein an adjusting baffle is slidably connected inside the feeding bin, and a step mechanism is provided at one end of the adjusting baffle near the movable and fixed stepped plates, the step mechanism comprising multiple step units that engage the movable and fixed stepped plates; a telescopic mechanism disposed within the step units to tightly connect the adjusting baffle with the movable and fixed stepped plates; and a sliding mechanism installed on the stepped nail feeder to drive the adjusting baffle to slide horizontally within the feeding bin.

[0005] Optionally, the telescopic mechanism includes a telescopic slide groove formed in the step unit, and a return spring is fixedly connected inside the telescopic slide groove. The end of the return spring away from the inner wall of the telescopic slide groove is fixedly connected to a telescopic spring rod that tightly abuts against the movable step plate.

[0006] Optionally, the sliding mechanism includes a screw rod, one end of which spirally passes through the feeding hopper and is rotatably connected to the middle of the adjusting baffle. The other end of the screw rod is fixedly connected to a connecting plate, and a hand crank is rotatably connected to the end of the connecting plate away from the screw rod.

[0007] Optionally, the outer wall of the stepped nail feeder is fixedly connected with a limiting sleeve that is movably sleeved with the spiral rod.

[0008] Optionally, the feed hopper is provided with an inclined guide trough inside.

[0009] Optionally, a pair of fixing holes are provided at both ends of the fixed step plate.

[0010] Optionally, the bottom of the stepped nail feeder is provided with multiple support frames arranged horizontally and vertically in a crisscross pattern and fixedly connected by welding.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes an adjustable baffle, a telescopic mechanism, and a sliding mechanism. Rotating the hand crank drives a screw rod to move the adjustable baffle horizontally. A stepped mechanism holds the stepped plate in place, and a telescopic spring rod provides additional support. The length of the stepped plate can be adjusted according to the screw length.

[0024] Example

[0025] As shown in Figures 1 to 4, this utility model proposes an automatic nail feeding device for an automotive production line, including a stepped nail feeder 1 and multiple staggered movable step plates 2 and fixed step plates 3 arranged within the stepped nail feeder 1. The movable step plates 2 and fixed step plates 3 are staggered and driven by a drive mechanism to reciprocate, responsible for "scooping up" and pushing screws to higher steps. The fixed step plates 3 are fixed to the inside of the frame or hopper and are arranged in a stepped, inclined manner, providing a support track for the screws to slide along, defining the screw path and posture. A feeding hopper 6 is provided inside the stepped nail feeder 1, which is used to store screws and houses an adjusting baffle 4 and a guide chute 5. The guide chute 5 is inclined inside the feeding hopper 6, and uses gravity to guide screws that fail to reach the next process to slide down to the stepped track. An adjusting baffle 4 is slidably connected inside the feeding hopper 6. The adjusting baffle 4 is slidably connected within the feeding hopper 6, and one end is equipped with a stepped mechanism 44. The length of the movable stepped plate 2 and the fixed stepped plate 3 can be adjusted by translation to accommodate different screws. The stepped mechanism 44 is located at the front end of the adjusting baffle 4 near the movable stepped plate 2 and the fixed stepped plate 3. It comprises multiple stepped units and is used to lock the movable stepped plate 2 and the fixed stepped plate 3, assisting in adjusting the distance between them. The step mechanism 44 includes multiple step units that engage the movable step plate 2 and the fixed step plate 3. The step unit is a component of the step mechanism 44 and is located at one end of the adjusting baffle 4 near the movable step plate 2 and the fixed step plate 3. Its function is to engage the movable step plate 2 and the fixed step plate 3. When the adjusting baffle 4 is driven to move by the screw rod 41, the engagement relationship between the step unit and the step plate helps to adjust the length of the movable step plate 2 and the fixed step plate 3, thereby adapting to the conveying requirements of screws of different lengths.

[0026] As shown in Figures 3 and 4, the stepped unit is equipped with a telescopic mechanism that tightly connects the adjusting baffle 4 to the movable stepped plate 2 and the fixed stepped plate 3. The telescopic mechanism includes a telescopic groove 401 within the stepped unit, providing space for the return spring 402 and the telescopic spring rod 403. A return spring 402 is fixedly connected inside each telescopic groove 401. The return spring 402 pushes the telescopic spring rod 403 against the movable stepped plate 2 through its elastic force, ensuring the adjusting baffle is tightly against the stepped plate. The end of the return spring 402 away from the inner wall of the telescopic groove 401 is fixedly connected to the telescopic spring rod 403, which tightly abuts against the movable stepped plate 2. When the telescopic spring rod 403 extends, it tightly abuts against the movable stepped plate 2, assisting in fixing the position of the adjusting baffle.

[0027] Additionally, as shown in Figures 2 to 4, the stepped nail feeder 1 is equipped with a sliding mechanism that drives the adjusting baffle 4 to slide and translate within the feeding bin 6. This sliding mechanism includes a spiral rod 41, one end of which is rotatably connected to the adjusting baffle 4, and the other end connected to a hand crank 43 via a connecting plate 42. Rotation of the spiral rod 41 drives the adjusting baffle to slide horizontally. One end of the spiral rod 41 spirally passes through the feeding bin 6 and is rotatably connected to the middle of the adjusting baffle 4. The other end of the spiral rod 41 is fixedly connected to the connecting plate 42, which is fixed to the end of the spiral rod 41 and connected to the hand crank 43, transmitting rotational power. The end of the connecting plate 42 furthest from the spiral rod 41 is rotatably connected to the hand crank 43, which is manually turned. The hand crank 43 drives the spiral rod 41 to rotate via the connecting plate 42, thus adjusting the position of the adjusting baffle.

[0028] It is worth noting that, as shown in Figure 1, the outer wall of the stepped nail feeder 1 is fixedly connected with a limiting sleeve 11 that is movably sleeved with the spiral rod 41. The function of the limiting sleeve 11 is to limit the radial displacement of the spiral rod 41, ensuring that it maintains axial stability when rotating to drive the adjusting baffle 4 to move, avoiding the decrease in adjustment accuracy or wear of parts due to shaking, and improving the reliability of the device operation and the service life of the adjusting mechanism.

[0029] Furthermore, as shown in Figures 2 and 4, a pair of fixing holes 31 are provided at both ends of the fixed step plate 3. The fixing holes 31 are used to fix the position of the step plate to ensure structural stability.

[0030] Furthermore, as shown in Figure 1, the bottom of the stepped nail feeder 1 is provided with multiple support frames 7 arranged horizontally and vertically and fixedly connected by welding. The support frames 7 are located at the bottom of the stepped nail feeder 1 and are welded horizontally and vertically to provide stable support.

[0031] In this embodiment, when using the automatic nail feeding device for the automotive production line, the screw is first placed in the feeding bin 6, and the screw will automatically slide down to the stepped track formed by the intersecting fixed step plate 3 and movable step plate 2. Turning the hand crank 43 drives the screw rod 41 to rotate via the connecting plate 42. Since the screw rod 41 is helically connected to the feeding bin 6, it can drive the adjusting baffle 4 to slide horizontally within the feeding bin 6. Then, the stepped unit of the stepped mechanism 44 locks the movable step plate 2 and the fixed step plate 3 in place. Simultaneously, the telescopic spring rod 403 of the telescopic mechanism, under the action of the return spring 402, tightly presses against the movable step plate 2, thus ensuring that the adjusting baffle 4 is tightly connected to the movable step plate 2 and the fixed step plate 3. This allows for convenient and quick adjustment of the lengths of the movable step plate 2 and the fixed step plate 3 according to the screw length.

[0032] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
