Description

Technical Field

[0001] This utility model relates to the field of metal product manufacturing technology, specifically to a feeding device for metal products. Background Technology

[0002] In the manufacturing fields of electronics, automobiles, and precision instruments, springs are used more and more widely as key metal products that realize functions such as conductivity, elastic support, and signal transmission. With the advancement of intelligent manufacturing, downstream assembly lines are generally developing towards high speed and automation, which puts forward stringent requirements on the continuity, stability, and efficiency of spring supply. Once the supply is interrupted, the entire assembly line will come to a standstill, directly affecting the production cycle and product qualification rate.

[0003] Currently, the manual feeding mode for spring clips is still used in some small and medium-sized enterprises. Workers need to manually sort, orient, and feed the stacked spring clips into the subsequent processing station. This is not only labor-intensive and costly, but also results in uneven feeding rhythm due to the randomness of manual operation, making it difficult to match the continuous operation requirements of automated production lines. Furthermore, it is easy to cause quality problems such as oil stains and scratches on the surface of the spring clips due to hand contact. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for metal products, including a mounting platform, a rotating shelf mechanism mounted on the back of the mounting platform, a rotating shelf mechanism that can hold multiple sets of rectangular material cylinders, a front block fixed on the front of the mounting platform, a guide plate fixed on one side of the front block opposite to the material feeding end of the rotating shelf mechanism, a vibration motor connected to the bottom of the guide plate mounted on the mounting platform; the rotating shelf mechanism includes a fixed base, a C-shaped disk fixed on the top of the fixed base, a notch opened on the side opposite to the opening of the C-shaped disk, a support disk for supporting the material cylinder fixed on the top of the C-shaped disk, the diameter of the support disk being larger than the diameter of the C-shaped disk, and a material feeding port opened on the support disk opposite to the notch and the guide plate, a rotating shaft rotatably connected to the top of the fixed base passing through the C-shaped disk and the support disk, a drive shaft rotation drive unit mounted on the mounting platform, two sets of opening plates fixed on the outer side of the rotating shaft, the two sets of opening plates being spaced a certain distance apart, and spring plates that are in close contact with the side of the material cylinder fixed on the top of each opening plate near the opening.

[0005] Furthermore, the drive unit includes a template disk rotatably connected to the top of the fixed base and passing through a rotating shaft. A ratchet is fixed to the outside of the rotating shaft. The template disk is located inside the C-shaped disk, and the protruding end of the template disk is located at the opening of the C-shaped disk. A push cylinder is hinged to the mounting platform and hinged to the protruding end of the template disk. Pads that mesh with the ratchet are torsionally installed on the protruding end of the template disk and on the surface of the C-shaped disk. A stop block is fixed near the corresponding pawl on one side of the template disk and the top of the C-shaped disk.

[0006] Furthermore, a side plate is fixed to the front of the mounting platform, a push cylinder is installed on the top of the side plate, a push plate is fixed to the ejector end of the push cylinder, the guide plate is located inside the push plate, and a stop pin that can extend into the interior of the guide plate is fixed to one side of the guide plate.

[0007] Furthermore, the push plate is divided into a left plate and a right plate, and the right plate is L-shaped, and the top of the right plate is an open rectangular frame plate. Therefore, the guide plate is located inside the rectangular frame plate. The left plate is also L-shaped, and the angle of the left plate is obtuse. The stop pin is fixed on the left plate.

[0008] Furthermore, a vertical plate is fixed on the platform of the mounting table, a sliding groove is formed on the top of the vertical plate, and a limiting plate is fixed above the sliding groove. A front-push cylinder is installed on one side of the vertical plate, and a receiving block fixed to the piston rod of the front-push cylinder is slidably connected to the top of the vertical plate. A placement groove is opened on the top of the receiving block, which can be connected to the tail end of the guide plate to receive materials.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] The feeding device for this metal product can hold multiple sets of material cylinders through a rotating shelf mechanism. The drive unit realizes the intermittent and precise rotation of the material cylinders. Combined with the vibrating motor to assist in feeding and the push cylinder to quantitatively push, it ensures a stable feeding rhythm for the spring pieces and avoids production line stagnation caused by feeding interruptions. It can match the cycle time requirements of high-speed automated production lines. The rotating shelf mechanism realizes the automatic switching of feeding multiple sets of material cylinders.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This embodiment of a metal product feeding device includes a mounting platform 1, which is a combination of a vertical plate on the left and a seat on the right. A rotating shelf mechanism 2 for storing and conveying material cylinders 10 is fixedly installed on the back of the vertical plate. Multiple sets of rectangular material cylinders 10 can be placed circumferentially in the rotating shelf mechanism 2. Each set of material cylinders 10 contains stacked metal springs to be fed. A front block 4 is fixed on the front of the mounting platform 1. A guide plate 5 opposite to the feeding end of the rotating shelf mechanism 2 is fixed on the right side of the front block 4. The guide plate 5 is the conveying channel for the springs from the material cylinders 10. A vibration motor 51 connected to the bottom of the guide plate 5 is fixedly installed on the front of the vertical plate. When the vibration motor 51 is working, it can drive the guide plate 5 to generate high-frequency micro-amplitude vibration, which helps the springs move smoothly along the guide plate 5 and avoids the springs getting stuck.

[0018] like Figure 2-3The rotating shelf mechanism 2 includes a fixed base 21, a C-shaped disk 22, a support disk 23, a rotating shaft, and a drive unit. The fixed base 21 is fixed to the back of the vertical plate of the mounting platform 1, providing fixed support for the rotating shelf mechanism 2. The C-shaped disk 22 is fixed to the top of the fixed base 21, with its opening facing away from the vertical plate of the mounting platform 1. A notch 25 is provided on the side of the C-shaped disk 22 opposite to the opening, which is used to avoid the falling path of the material cylinder 10. The support disk 23 is fixed to the top of the C-shaped disk 22, and its diameter is larger than that of the C-shaped disk 22, which can provide stable support for the bottom of the material cylinder 10. A discharge port 24 is provided on the support disk 23, which corresponds to the position of the notch 25 and is opposite to the feeding end of the guide plate 5. The discharge port 24 is adapted to the spring piece inside the material cylinder 10. When the material cylinder 10 rotates to above the discharge port 24, the spring piece inside the material cylinder 10 can fall into the guide plate 5 through the discharge port 24. The material plate 5, the rotating shaft 211 is rotatably connected to the top of the fixed base 21 via bearings, and passes through the center of the C-shaped disk 22 and the support disk 23. Two sets of opening plates 213 are fixed on the outside of the rotating shaft 211. Multiple slots are opened on the outside of the opening plates 213. The two sets of opening plates 213 are distributed vertically and spaced a certain distance apart. The slots of the two sets of opening plates 213 are opposite each other, and a set of material cylinders 10 can be clamped at the same time between the upper and lower slots. A spring plate 214 is fixed near the opening at the top of the opening plate 213. The spring plate 214 is made of elastic metal and can fit tightly against the side of the material cylinder 10 to achieve elastic clamping of the material cylinder 10 and prevent the material cylinder 10 from shaking or tipping over during rotation. The drive unit is installed on the back of the vertical plate of the mounting platform 1 and is used to drive the rotating shaft to rotate intermittently, thereby driving the opening plates 213 to clamp the material cylinders 10 and move them circumferentially, so as to realize the sequential feeding of multiple sets of material cylinders 10.

[0019] The driving unit includes a mold plate 210, a ratchet 26, a pawl 28, a push cylinder 29, and a stop block 27. The mold plate 210 has a fan-shaped structure and is rotatably connected to the top of the fixed base 21 and located inside the C-shaped disk 22. Its protruding end extends to the opening of the C-shaped disk 22. The push cylinder 29 is hinged to the back of the vertical plate of the mounting platform 1, and its piston rod is hinged to the protruding end of the mold plate 210. When the piston rod of the push cylinder 29 extends or retracts, it can drive the mold plate 210 to swing around the rotating shaft 211. The ratchet 26 is fixed to the outside of the rotating shaft 211 and located above the mold plate 210. Pawls 28 that mesh with the ratchet 26 are installed on the protruding end of the mold plate 210 and on the surface of the C-shaped disk 22 through torsion springs. The torsion springs can keep the pawls 28 in a constant state of engagement with the ratchet 26. The stop block 27 is fixed to the mold plate 210. The inward-facing side of the protruding end of the disc 210 and the top of the C-shaped disc 22 near the corresponding pawl 28 are used to limit the maximum rotation angle of the pawl 28, ensuring stable engagement between the pawl 28 and the ratchet 26. When the piston rod of the push cylinder 29 extends, it drives the die disc 210 to swing clockwise. At this time, the pawl 28 on the die disc 210 drives the ratchet 26 to rotate clockwise, thereby driving the rotating shaft 211 to rotate. When the piston rod of the push cylinder 29 retracts, the die disc 210 swings counterclockwise. Because the pawl is hinged, the pawl on the die disc is separated from the ratchet by the slope of the ratchet and enters the next engagement. At this time, the pawl 28 on the C-shaped disc 22 holds the ratchet, preventing the die disc 210 from retracting and causing the ratchet 26 to rotate, thus driving the rotating shaft to rotate. Therefore, the rotating shaft 211 is intermittently rotated in one direction, ensuring that the material cylinder 10 can be accurately rotated to the discharge port 24 position.

[0020] like Figure 4 The front of the mounting platform 1 is also fixed with a side plate 52 located on the right side of the guide plate 5. A push cylinder 53 opposite to the guide plate 5 is installed on the top of the side plate 52. A push plate 54 is fixed to the ejector end of the push cylinder 53. The guide plate 5 is located inside the push plate 54. A stop pin 55 that can extend into the guide groove of the guide plate 5 is fixed on the left side of the push plate 54. By pushing out the push cylinder, the stop pin 55 can initially limit the spring piece in the guide groove, thereby realizing the quantitative conveying of the spring piece.

[0021] Further explanation: The push plate 54 is composed of a left plate and a right plate. The right plate is L-shaped, and its top forms an open rectangular frame. The first end of the guide plate 5 is located inside the rectangular frame, which can limit the vertical displacement of the spring piece. The left plate is L-shaped with an obtuse angle. The stop pin 55 is fixed on the left plate and is opposite to the guide plate 5. By the reciprocating movement of the push plate, the stop pin is driven to insert into the guide plate to limit the falling spring piece and stably block the spring piece.

[0022] Additionally, a vertical plate 6 is fixed on the mounting platform 1. A sliding groove is provided on the top of the vertical plate 6, and a limiting plate 8 is fixed above the sliding groove. A receiving block 9 is slidably connected in the sliding groove. The limiting plate 8 can prevent the receiving block 9 from detaching from the top of the sliding groove, and can also accommodate the detachment of the spring sheet. A front-push cylinder 7 is installed on the front of the vertical plate 6. The receiving block 9 is fixed to the piston rod of the front-push cylinder 7. A placement groove is provided on its top to align with the tail end of the guide plate 5. When the spring sheet falls into the placement groove, the piston rod of the front-push cylinder 7 extends, driving the receiving block 9 to slide along the sliding groove to the next processing station, completing the transfer of the spring sheet. At the same time, the receiving block 9 can also block the outlet at the tail end of the guide plate 5. Then, the piston rod of the front-push cylinder 7 retracts, and the receiving block 9 resets, ready to receive the next spring sheet.

[0023] The working principle of the above embodiments is as follows:

[0024] In the initial state, multiple rectangular cylinders equipped with stacked spring clips are clamped and fixed by the latches of two sets of opening plates. Spring clips are tightly fitted against the sides of the cylinders to prevent wobbling. At this time, one set of cylinders is aligned with the feed port of the support plate, and the spring clips can initially enter the guide plate. When the spring clips of this cylinder are about to be used up, the drive unit starts switching, pushing the piston rod of the cylinder to extend, causing the mold plate to swing clockwise. Its pawl engages with the ratchet, pushing the rotating shaft to rotate, which in turn drives the opening plate to move the cylinder clamped in place. After the piston rod retracts, the mold plate swings counterclockwise, and its pawl separates from the ratchet. The pawl on the C-shaped plate locks the ratchet to prevent backflow, and the next set of cylinders precisely rotates to the feed port, completing the intermittent process. The feeding switch ensures a continuous supply of spring sheets. After the spring sheets fall from the discharge port into the guide plate, the vibration motor on the vertical plate starts, driving the guide plate to generate high-frequency micro-amplitude vibration. This prevents the spring sheets from getting stuck due to stacking friction and ensures that they move smoothly to the right along the guide groove. When the spring sheet moves to the middle, the piston rod of the push cylinder on the side plate pushes out, driving the push plate to move to the left. The stop pin of the left plate inserts into the guide groove to block the subsequent spring sheets, realizing quantitative conveying and preventing multiple spring sheets from entering the transfer process at the same time. The spring sheet is sent to the placement groove of the receiving block. The forward push cylinder runs, and the receiving block moves along the vertical plate slide groove, so that the placement groove is opposite to another process. At the same time, the receiving block can block the discharge port of the guide plate.

[0025] Throughout the entire process, the intermittent feeding of the rotating shelf mechanism, the auxiliary conveying of the vibrating motor, the quantitative limiting of the pushing cylinder, and the transfer action of the receiving block are seamlessly connected to form a continuous and precise spring feeding closed loop, which meets the batch feeding needs of the automated production line.

[0026] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
