Description

Technical Field

[0001] This invention relates to the field of edge rolling machine technology, and more specifically, to an automatic end cap edge rolling machine with a dual-station I-beam wheel. Background Technology

[0002] H-beam reels, commonly used cable spools, play a crucial role in the production, transportation, and storage of cables and other electrical components. To protect the internal cables or optical fibers from damage, and to ensure the stability and durability of the reel, H-beam reels typically require end caps.

[0003] However, with the increasing consumption of products such as cables, the demand for I-beam reel end caps is also increasing. This necessitates an efficient and stable end cap crimping process to meet the needs of large-scale production. Traditional I-beam reel end cap crimping processes mostly rely on single-station semi-automatic equipment, requiring frequent manual loading and unloading, which is not only inefficient but also results in poor product consistency. In single-station operation mode, the crimping process and the loading and unloading process cannot be carried out in parallel, leading to high equipment idle rates. Steps such as pressing, crimping, and transferring need to be performed separately, further increasing time consumption and reducing efficiency.

[0004] Given the severe impact of the aforementioned problems on production efficiency, the industry urgently needs a solution that can significantly improve production efficiency. Therefore, this invention provides an innovative dual-station automatic end cap crimping machine with I-beam rollers. Summary of the Invention

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this invention clearer, the invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the invention, and therefore only shows the components relevant to the invention. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] like Figure 1 , Figure 2 As shown, the present invention provides an automatic end cap crimping machine 100 with two stations and an I-beam wheel, which is used to crimp end caps 4. The crimping machine 100 includes a feeding conveyor belt 1, a worktable 2, and an unloading conveyor belt 3. The feeding conveyor belt 1 is located on one side of the worktable 2, and the unloading conveyor belt 3 is located on the other side of the worktable 2.

[0022] In this embodiment, specifically: as follows: Figure 3 As shown, the feeding conveyor belt 1 is equipped with a track 11, the end of the feeding conveyor belt 1 is equipped with a limiting post 12, and the lower end of the track 11 is equipped with a positioning plate 13.

[0023] In this embodiment, specifically: the feeding conveyor belt 1 is provided with two tracks 11, the spacing between the two parallel tracks 11 is adjustable, and it can accommodate end caps with different outer diameters.

[0024] In this embodiment, specifically: the surface of the track 11 is patterned to prevent the end cap 4 from slipping and to increase friction.

[0025] In this embodiment, specifically: the positioning plate 13 has a limiting protrusion 131 protruding from the center, the positioning plate 13 is equipped with a sensor, and the positioning plate 13 can be replaced as a whole with the feeding conveyor belt 1 via a quick-release pin to adapt to end caps 4 with different center hole diameters.

[0026] In this embodiment, specifically: the end cap 4 is placed on the track 11. As the track 11 rotates, the end cap 4 is gradually conveyed to the end of the track 11. When the end cap 4 reaches the end of the loading conveyor belt 1, the limiting post 12 limits the end cap 4, making it stably stop at the upper end of the positioning plate 13. The limiting post 12 and the positioning plate 13 improve the positioning accuracy, ensuring that the end cap 4 can be accurately limited on the positioning plate 13 each time, guaranteeing the consistency and accuracy of subsequent processing or assembly processes, and reducing the product defect rate caused by positional deviation.

[0027] In this embodiment, specifically: the first workstation and the second workstation are symmetrically arranged on the workbench 2, and the devices of the first workstation and the second workstation are the same.

[0028] In this embodiment, specifically: as follows: Figure 4 , Figure 7 As shown, the worktable 2 includes a material transfer assembly 21, an edge rolling assembly 22, and an edge pressing assembly 23.

[0029] In this embodiment, specifically: as follows: Figure 8 , Figure 9 As shown, the material transfer assembly 21 includes a material transfer motor 211, cylinders 212 disposed on both sides of the material transfer motor 211, a fixing plate 213 fixed to the top of the cylinders 212, a robotic arm 214 fixed to the top of the material transfer motor 211, and an electromagnet 215 fixed to one end of the robotic arm 214 away from the material transfer motor 211.

[0030] In this embodiment, specifically: the transfer motor 211 is fixed on the fixed plate 213 and is fixedly connected to the robotic arm 214. The cylinder 212 controls the transfer motor 211 on the fixed plate 213 to move up and down. When the end cap 4 is transferred to the positioning plate 13, the cylinder 212 controls the robotic arm 214 to move up. The transfer motor 211 controls the robotic arm 214 to rotate to the upper end of the positioning plate 13. The cylinder 213 controls the robotic arm 214 to move down. The electromagnet 215 is energized, attracting the end cap 4 to one end of the robotic arm 214. The cylinder 213 controls the robotic arm 214 to move up. The transfer motor 211 controls the robotic arm 214 to rotate to the pressing assembly 23. The electromagnet 215 is de-energized. At this time, the end cap falls onto the pressing assembly 23.

[0031] In this embodiment, specifically: a slider 216 is bolted to the side of the housing of the transfer motor 211, and a slide rail 217 is fixed on the platform 24, and the slider 216 slides on the slide rail 217.

[0032] In this embodiment, specifically: the robotic arm 214 has a positioning hole 2141 at the end away from the material transfer component 21, and the end cover 4 has a through hole 41 at the center. When the end cover 4 is transferred to the positioning plate 13, the material transfer motor 211 controls the robotic arm 214 to rotate, and the positioning hole 2141 is aligned with the limiting protrusion 131 and the through hole 41.

[0033] In this embodiment, specifically: the robotic arm 214 at the first station transfers the end cap 4 from the loading conveyor belt 1 to the first station. After the end cap 4 is rolled at the first station, the robotic arm 214 at the second station transfers the end cap 4 to the unloading conveyor belt 3.

[0034] In this embodiment, specifically: as follows: Figure 5 , Figure 6 , Figure 10 , Figure 11 The edge-rolling assembly 22 includes an edge-rolling cylinder 221, a telescopic rod 222 connected to the edge-rolling cylinder 221, a connecting rod 223, a fixing block 224 connected to the connecting rod 223, and an edge-rolling wheel 225 fixed on the fixing block 224. The edge-rolling assembly 22 is responsible for rolling the edge of the end cap from a 90° right angle to a 270° edge, and ensuring the edge height, roundness, and wrinkle-free surface.

[0035] In this embodiment, specifically: the curling cylinder 221 drives the telescopic rod 222 to move forward, the front end of the telescopic rod 22 abuts against the connecting rod 223, the telescopic rod 222 pushes one end of the connecting rod 223 forward, the middle section of the connecting rod 223 forms a lever fulcrum through the rotating rod 228, and the end is connected to the fixed block 224 to form a "four-bar linkage" mechanism, so that the trajectory of the curling wheel 225 is a composite curve of "first radial fast advance, then axial slow curling", which not only ensures the curling efficiency, but also avoids material cracking caused by one extrusion.

[0036] In this embodiment, specifically: the hemming assembly 22 also includes a support rod 226, a limiting member 227 fixed on the workbench 2, and a rotating rod 228. One end of the support rod 226 is connected to one end of the connecting rod 223, the side of the support rod 226 is connected to the side of the hemming cylinder 221, and the connecting rod 223 is rotatably connected to the upper end of the rotating rod 228.

[0037] In this embodiment, specifically, the hemming assembly 22 further includes a support member 229, which is installed at the lower end of the connecting rod 223 and located at the end of the connecting rod 223 away from the limiting member 227. When the hemming cylinder 221 pushes the connecting rod 223 forward, one end of the connecting rod 223 is limited within the limiting member 227, while the other end is supported by the support member 229, thereby ensuring the stability of the connecting rod 223.

[0038] In this embodiment, specifically: as follows: Figure 12 , Figure 13As shown, the pressing assembly 23 includes a pressing cylinder 231, a pressing film 232, a positioning motor 234 and a positioning seat 235 fixed on the worktable 2. The pressing assembly 23 is responsible for axially pressing the end cap 4 and driving it to rotate during the pressing process, ensuring that the pressing wheel 225 maintains a constant contact force with the edge of the end cap, while preventing the end cap from jumping or warping.

[0039] In this embodiment, specifically: the workbench 2 also includes a table plate 24, a top plate 25 located on the upper end of the table plate 24, and a support column 26 supporting the table plate 24 and the top plate 25. The material transfer assembly 21, the edge rolling assembly 22, the positioning motor 234, and the positioning seat 235 are fixed on the material transfer assembly 21, and the film pressing cylinder 231 is fixed on the top plate 25.

[0040] The working process of the automatic end cap rolling machine with two stations and one I-beam wheel according to the present invention: The end cap 4 is first smoothly conveyed to its end position by the feeding conveyor belt 1. Then, the track 11 starts, continuing to transport the end cap 4 forward until it accurately reaches the top of the positioning plate 13. During this process, the end cap 4 is firmly fixed above the positioning plate 13 by the limiting post 12, ensuring its precise position. At this moment, the sensor quickly detects the presence of the end cap 4 and sends a signal. The transfer motor 211 at the first station responds immediately, driving the robotic arm 214 to start rotating. Simultaneously, the electromagnet 215 is energized, generating a strong magnetic force that firmly attracts the end cap 4 onto the robotic arm 214. The transfer motor 211 continues to control the robotic arm 214 to rotate. When the robotic arm 214 carrying the end cap 4 reaches the predetermined position of the positioning seat 235, the electromagnet 215 is de-energized, the magnetic force disappears, and the end cap 4 falls onto the positioning seat 235. Subsequently, the robotic arm 214 returns to the positioning plate 13, ready for the next operation. At this time, the pressing cylinder 231 starts, controlling the pressing film 232 to press downwards and ensure the end cap 4 is stable. The positioning motor 234 also starts working, driving the positioning seat 235 to rotate. At the same time, the edge-rolling cylinder 221 controls the telescopic rod 222 to move towards the positioning seat 235, and the groove 2251 tightly abuts against the edge of the end cap 4, starting the precise edge-rolling process for the end cap 4. After the edge-rolling process is completed, the edge-rolling wheel 225 moves to the end away from the robotic arm 214, making room for the next operation. Then, the robotic arm 214 on the second station starts again, picks up the edge-rolled end cap 4 located on the positioning seat 235 of the first station, and smoothly transfers it to the unloading conveyor belt 3, completing the entire process flow.

[0041] The beneficial effects of the present invention, a dual-station automatic end cap crimping machine with I-beam wheels, are as follows: 1. This equipment cleverly employs a dual-station design, successfully achieving parallel operation of the edge-rolling and loading / unloading processes. This design effectively reduces equipment downtime, enabling more efficient operation and significantly improving equipment utilization. Simultaneously, the automated operation greatly reduces the need for manual intervention, which not only reduces human error in the production process but also ensures product consistency and stability, ultimately significantly improving production efficiency and product quality, bringing higher economic benefits and stronger market competitiveness to the enterprise.

[0042] 2. The precise positioning of the end cap 4 is achieved through the combined action of the limiting protrusion 131 on the positioning plate 13, the precise positioning hole 2141 on the robotic arm 214, and the strong adsorption of the electromagnet 215. This series of ingenious designs and coordinated operations ensures that the end cap 4 accurately reaches its predetermined position during assembly, greatly improving assembly accuracy and efficiency, reducing assembly errors caused by inaccurate positioning, and thus guaranteeing the operational stability of the entire equipment and the reliability of product quality.
