Description

Technical Field

[0001] This invention relates to the field of photovoltaic product processing equipment technology, and more specifically, to a photovoltaic connector cutting, stripping and riveting integrated machine. Background Technology

[0002] Photovoltaic connectors are key components of solar cell modules. One end is used to connect to the junction box, and the other end has a male or female connector to realize the series clustering of single photovoltaic modules. The photovoltaic cable cutting, stripping, riveting and tightening integrated machine is a kind of equipment for processing photovoltaic cables. It integrates cutting, stripping, riveting and tightening functions and can quickly and efficiently complete the processing tasks of photovoltaic cables.

[0003] In existing integrated cutting, stripping, riveting and twisting machines, the loading of cables is relatively inconvenient. The manual handling of the loading increases the workload, and if the operator is too weak during handling, the photovoltaic cable reel may fall and injure the workers, thus reducing the safety of the equipment. A search revealed that Chinese patent CN221379971U discloses a photovoltaic cable cutting, stripping, riveting, and twisting integrated machine. This structure uses a drive motor to operate and a steel wire rope to pull the support frame up and down, along with a clamp to clamp the cable reel before loading it. This eliminates the hassle of manually carrying the photovoltaic cable reel upwards to install it on the platform, saving manpower and reducing workload. By using movable clamps in conjunction with fixed clamps and multiple clamping components, the photovoltaic cable reel is more stable when rotating during the cutting, stripping, riveting, and twisting process, reducing the overall tilting and shaking of the photovoltaic cable reel during rotation. This helps improve the stability of the photovoltaic cable when it enters the cable feeding and straightening station.

[0004] Although the structure achieves stable feeding and straightening of cable reels, its cutting and stripping actions lack effective coordination. Each process is relatively independent, making it difficult to complete fixed-length cutting and outer sheath removal sequentially during the conveying process. This results in processing accuracy being limited by the positioning errors of manual or auxiliary devices. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a photovoltaic connector cutting, stripping and riveting integrated machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A photovoltaic connector cutting, stripping and riveting integrated machine includes a frame, on which a cable feeding mechanism for conveying cables, a stripping component for stripping the outer sheath of cables, and a riveting component for riveting connectors are sequentially arranged. The infeed mechanism includes a fixed frame fixedly mounted on the top of the frame, a movable frame slidably mounted inside the fixed frame, a first electric telescopic rod fixedly mounted on the top of the fixed frame, the output end of the first electric telescopic rod fixedly connected to the top of the movable frame, an upper guide wheel rotatably mounted on the inner wall of the movable frame, a motor fixedly mounted on one side of the fixed frame, a lower guide wheel fixedly mounted on the output end of the motor, and one end of the lower guide wheel rotatably connected to the inner wall of the fixed frame. An extension plate is fixedly installed on the surface of the fixed frame, a first cylinder is fixedly installed on the top of the extension plate, a cutter is fixedly installed at the output end of the first cylinder, and a cutter plate is fixedly installed on one side of the fixed frame at the bottom of the cutter. A slider is fixedly installed on one side of the cutter, and a groove matching the slider is opened on the surface of the fixing frame.

[0007] By adopting the above technical solution, the distance between the upper guide wheel and the lower guide wheel can be automatically adjusted to adapt to cables of different diameters, and the precise guidance of the slider and the groove ensures that the cutter can be lifted and lowered vertically for cutting, thereby effectively improving the stability of wire feeding and the flatness of the cutting surface.

[0008] As a further description of the above technical solution: the peeling assembly includes a second electric telescopic rod fixedly installed on the side of the fixing frame away from the extension plate, a support frame is fixedly provided at the output end of the second electric telescopic rod, a drive mechanism is fixedly installed at the top of the support frame, an upper peeling knife is fixedly provided at the output end of the drive mechanism, and a lower peeling knife is fixedly provided on one side of the support frame. A stabilizing frame is fixedly installed on one side of the fixed frame, and the stabilizing frame is slidably connected to the support frame.

[0009] By adopting the above technical solution, the second electric telescopic rod can drive the upper and lower peeling knives to quickly clamp the outer skin and retract and pull it off. At the same time, the stabilizing frame slides and guides the support frame to prevent deviation, thereby effectively improving peeling efficiency and peeling accuracy.

[0010] As a further description of the above technical solution: an electric push rod is fixedly installed on one side of the stabilizer, and a conveying seat is fixedly provided at the output end of the electric push rod; The top of the conveyor seat is fixedly provided with a clamp for holding the cable, and the surface of the stabilizer is fixedly provided with a guide rod, and the conveyor seat is slidably connected to the guide rod; The riveting assembly includes a mounting bracket installed on the top of the frame, and a second cylinder is fixedly mounted on the top of the mounting bracket; An upper pressure mold is fixedly installed at the output end of the second cylinder, and a lower pressure mold is fixedly installed at the top of the frame at the bottom of the upper pressure mold.

[0011] By adopting the above technical solution, the electric push rod can drive the cable-holding conveyor seat to slide smoothly along the guide rod to the riveting station, and cooperate with the upper and lower pressure molds to close and rivet, thereby realizing the automatic connection of the entire cutting, stripping and riveting process, improving processing efficiency and riveting quality.

[0012] The technical effects and advantages of this invention are as follows: 1. The cable feeding mechanism of this invention uses a first electric telescopic rod to drive a moving frame, which in turn raises and lowers the upper guide wheel. The distance between the upper guide wheel and the lower guide wheel can be automatically adjusted according to the cable diameter, enabling adaptive clamping and conveying of cables of different specifications. This effectively prevents slippage and deviation. During cutting, the first cylinder drives the cutting blade to cut the cable in conjunction with the cutting blade plate. The guide structure of the slider and the slide groove ensures that the cutting blade rises and falls vertically, ensuring a flat and accurate cut. In the stripping assembly, the second electric telescopic rod pushes the support frame closer to the cable. The upper and lower stripping blades quickly clamp the outer sheath and then retract and pull it off. The stripping is continuous and efficient. At the same time, the stabilizing frame slides and guides the support frame to prevent deviation, ensuring smooth and accurate stripping. The overall structure is compact, the cutting and stripping processes are smoothly connected, the degree of automation is high, and the processing quality is stable and reliable.

[0013] 2. The riveting assembly of this invention works in conjunction with the conveying mechanism. The electric push rod on one side of the stabilizer drives the conveying seat to slide smoothly along the guide rod. After the cable is stripped, the clamp holds and fixes it and accurately pushes it to the riveting station, realizing the automatic connection of the entire process of cutting, stripping and riveting. There is no need for manual transfer of the cable between processes, which significantly improves processing efficiency and automation level. The guide rod accurately guides the conveying seat to prevent deflection and ensures that the cable end accurately enters between the upper and lower pressure molds. The second cylinder drives the upper pressure mold to press down quickly and closes with the lower pressure mold to rivet the connector to the cable end. The riveting pressure is uniform and the action is rapid, ensuring the connection is firm and consistent, and greatly improving the product yield. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Example 1 like Figure 1-5 As shown, this embodiment provides a photovoltaic connector cutting, stripping and riveting integrated machine, including a frame 1, on which a cable feeding mechanism for conveying cables, a stripping component for stripping the outer sheath of cables and a riveting component for riveting connectors are sequentially arranged. The infeed mechanism includes a fixed frame 2 fixedly installed on the top of the frame 1, a movable frame 3 slidably installed inside the fixed frame 2, a first electric telescopic rod 4 fixedly installed on the top of the fixed frame 2, the output end of the first electric telescopic rod 4 fixedly connected to the top of the movable frame 3, an upper guide wheel 5 rotatably installed on the inner wall of the movable frame 3, a motor 6 fixedly installed on one side of the fixed frame 2, a lower guide wheel 7 fixedly installed on the output end of the motor 6, and one end of the lower guide wheel 7 rotatably connected to the inner wall of the fixed frame 2. An extension plate 8 is fixedly installed on the surface of the fixed frame 2. A first cylinder 9 is fixedly installed on the top of the extension plate 8. A cutter 10 is fixedly installed at the output end of the first cylinder 9. A cutter plate 11 is fixedly installed on one side of the fixed frame 2 at the bottom of the cutter 10. A slider 12 is fixedly installed on one side of the cutter 10, and a groove matching the slider 12 is opened on the surface of the fixing frame 2. The peeling assembly includes a second electric telescopic rod 13 fixedly installed on the side of the fixed frame 2 away from the extension plate 8. A support frame 14 is fixedly installed at the output end of the second electric telescopic rod 13. A drive mechanism is fixedly installed on the top of the support frame 14. An upper peeling knife 15 is fixedly installed at the output end of the drive mechanism. A lower peeling knife 16 is fixedly installed on one side of the support frame 14. A stabilizing frame 17 is fixedly installed on one side of the fixing frame 2, and the stabilizing frame 17 is slidably connected to the support frame 14.

[0022] As can be seen, in the above technical solution, the first electric telescopic rod 4 drives the moving frame 3 to lift the upper guide wheel 5, which can automatically adjust the distance with the lower guide wheel 7 according to the cable diameter, realize the adaptive pressing and conveying of cables of different specifications, effectively prevent slippage and deviation, and improve the stability and applicability of cable delivery. During cutting, the first cylinder 9 drives the cutting blade 10 to work with the cutting plate 11 to cut the cable. The guide structure of the slider 12 and the slide groove ensures that the cutting blade rises and falls vertically, ensuring a flat cut and accurate cutting. In the peeling assembly, the second electric telescopic rod 13 pushes the support frame 14 closer to the cable, and the upper peeling blade 15 and the lower peeling blade 16 quickly clamp the outer skin. When it retracts, it is pulled off in a smooth and efficient peeling action. The stabilizer 17 and the support frame 14 slide together to provide auxiliary support and guidance for the peeling process, prevent deviation and shaking, improve the stability of movement and peeling accuracy. The overall structure is compact, the process is smoothly connected, the degree of automation is high, and the processing quality is stable and reliable.

[0023] Usage process: When in use, the operator first passes the end of the cable to be processed through the gap between the upper guide wheel 5 and the lower guide wheel 7, and then starts the first electric telescopic rod 4. The output end of the first electric telescopic rod 4 extends downward, pushing the moving frame 3 to slide downward along the inner wall of the fixed frame 2. The moving frame 3 drives the upper guide wheel 5 to move downward synchronously until the wheel surface of the upper guide wheel 5 is in close contact with the upper surface of the cable. At the same time, the lower guide wheel 7 provides support to the lower surface of the cable, and the upper guide wheel 5 and the lower guide wheel 7 together clamp and press the cable. At this time, both the upper guide wheel 5 and the lower guide wheel 7 can rotate freely, which not only achieves the limitation and constraint of the cable, but also does not damage the surface of the cable. Next, start motor 6. The output of motor 6 drives the lower guide wheel 7 to rotate. The lower guide wheel 7 drives the cable to move forward through the friction between its wheel surface and the cable. At the same time, the upper guide wheel 5 rotates in the opposite direction under the drive of the cable, which plays an auxiliary guiding and pressing role in the cable conveying. The cable is continuously conveyed forward under the drive of the guide wheel, and passes through the subsequent stripping station and riveting station in sequence. When the cable is delivered to the set length, the motor 6 stops running and the cable stops moving. At this time, the first cylinder 9 is activated, and the output end of the first cylinder 9 extends downward, pushing the cutter 10 to move downward. The cutter 10 drives the slider 12 to slide downward along the groove on the surface of the fixed frame 2. The cooperation between the groove and the slider 12 ensures that the movement trajectory of the cutter 10 is always vertically downward until the cutting edge of the cutter 10 cooperates with the upper surface of the cutter plate 11, cutting the cable located between the cutter 10 and the cutter plate 11, completing the cutting operation. After the cutting is completed, the first cylinder 9 drives the cutter 10 to move upward back to the initial position. After the cable is cut, the cut independent cable segments are clamped and fixed by the clamp 20. The clamping force of the clamp 20 ensures that the cable segments will not come loose during subsequent transfer. Then, the electric push rod 18 is activated, and the electric push rod 18 pushes the conveyor seat 19 to slide along the guide rod 21 towards the stripping station. The conveyor seat 19 drives the clamp 20 and the cable segments it holds to move forward synchronously, thereby accurately conveying the cut cable segment ends to the stripping station. At this time, the second electric telescopic rod 13 is activated, which drives the support frame 14 to slide along the stabilizer 17 towards the cable. The support frame 14 drives the upper stripping blade 15 and the lower stripping blade 16 to move synchronously until the outer sheath of the cable end is between the upper stripping blade 15 and the lower stripping blade 16. Then, the drive mechanism at the top of the support frame 14 is activated. The drive mechanism drives the upper stripping blade 15 to move downward. The blade of the upper stripping blade 15 first contacts and cuts into the cable sheath. At the same time, the blade of the lower stripping blade 16 cuts into the outer sheath from below. Both the upper stripping blade 15 and the lower stripping blade 16 are blade structures. The depth of cutting into the outer sheath is controlled by the stroke of the drive mechanism. This stroke is preset to ensure that the blade only penetrates the thickness of the outer sheath without damaging the internal core wire. After cutting, the blades of the upper stripping blade 15 and the lower stripping blade 16 form a clamping state inside the outer sheath, clamping the outer sheath of the cable end. Next, before the second electric telescopic rod 13 is activated to reverse its action, the clamp 20 maintains a clamping and fixing state on the middle part of the cable. At the same time, the sliding engagement between the conveyor seat 19 and the guide rod 21 keeps the clamp 20 stationary during the stripping process, thereby firmly constraining the cable body in the current position. Then the second electric telescopic rod 13 moves in the opposite direction, causing the support frame 14 to slide along the stabilizer 17 away from the cable. The support frame 14 causes the upper stripping blade 15 and the lower stripping blade 16 to move backward in sync. The upper stripping blade 15 and the lower stripping blade 16 clamp the cut outer sheath and peel it off from the cable core, completing the stripping operation. The stripped outer sheath falls off automatically and is collected under the action of gravity. At this point, the outer sheath of the cable end has been completely removed, exposing the internal metal core wire. The cable then continues to be conveyed forward to the riveting station, ready for subsequent connector riveting operations.

[0024] Example 2 like Figure 4-5 As shown, this embodiment provides a photovoltaic connector cutting, stripping and riveting integrated machine. An electric push rod 18 is fixedly installed on one side of the stabilizer 17, and a conveyor seat 19 is fixedly provided at the output end of the electric push rod 18. A clamp 20 for holding cables is fixedly installed on the top of the conveyor seat 19, and a guide rod 21 is fixedly installed on the surface of the stabilizer 17. The conveyor seat 19 is slidably connected to the guide rod 21. The riveting assembly includes a mounting bracket 22 mounted on the top of the frame 1, and a second cylinder 23 is fixedly mounted on the top of the mounting bracket 22; The output end of the second cylinder 23 is fixedly provided with an upper pressure mold 24, and the top of the frame 1 is fixedly provided with a lower pressure mold 25 at the bottom of the upper pressure mold 24.

[0025] As can be seen, in the above technical solution, by setting an electric push rod 18 on the stabilizer 17, the output end of which is connected to the conveyor seat 19 with a clamp 20, the cable is fixed by the clamp 20 after stripping, and the electric push rod 18 drives the conveyor seat 19 to slide smoothly along the guide rod 21, accurately pushing the cable to the riveting station, thus realizing the automatic connection of the cutting, stripping and riveting processes. The guide rod 21 precisely guides the conveyor seat 19 to prevent skewing and ensure that the cable end accurately enters the riveting position, thus improving the riveting accuracy. In the riveting assembly, the mounting bracket 22 is fixed to the frame 1. The top second cylinder 23 drives the upper pressure mold 24 and the lower pressure mold 25 to close, quickly and evenly applying pressure to rivet the connector to the cable end, ensuring a firm and consistent connection.

[0026] Usage process: After the cable passes through the feeding mechanism, cutting and stripping components, the metal core wire at the end of the cable is completely exposed. At this time, the cable continues to be fed forward to the front end of the riveting station. The operator puts the connector to be riveted onto the exposed core wire at the end of the cable, aligning the inner hole of the connector with the core wire. At the same time, the clamp 20 is activated, and the jaws of the clamp 20 tighten, clamping and fixing the middle part of the cable from both sides to ensure that the cable remains stable and does not shake during the subsequent pushing process.

[0027] After clamping is completed, the electric push rod 18 is activated. The output end of the electric push rod 18 extends and pushes the conveyor seat 19 to slide along the guide rod 21 toward the riveting assembly. The guide rod 21 passes through the interior of the conveyor seat 19 and guides and limits the sliding of the conveyor seat 19, so that the conveyor seat 19 always maintains linear movement. The conveyor seat 19 drives the clamp 20 on its top to move synchronously. The clamp 20 clamps the cable and moves forward together, accurately pushing the part of the cable end with the connector onto the riveting station, so that the cable end is located in the cavity of the lower die 25, and the connector is aligned with the cavity of the lower die 25.

[0028] After the cable is positioned, the second cylinder 23 is activated. The output end of the second cylinder 23 extends downward and pushes the upper pressure mold 24 to move vertically downward along the guide structure of the mounting bracket 22. The mold cavity of the upper pressure mold 24 gradually approaches the lower pressure mold 25. When the upper pressure mold 24 and the lower pressure mold 25 are fully closed, the upper pressure mold 24 and the lower pressure mold 25 together apply radial pressure to the connector, pressing and deforming the metal shell of the connector, so that it is tightly riveted to the metal core of the cable, forming a strong electrical and mechanical connection. After riveting is completed, the second cylinder 23 drives the upper pressure mold 24 to retract upwards, and the upper pressure mold 24 disengages from the lower pressure mold 25. Then the electric push rod 18 moves in the opposite direction, the output end retracts, and the conveyor seat 19 slides along the guide rod 21 away from the riveting assembly. The conveyor seat 19 drives the clamp 20 and the completed riveting cable to move backwards synchronously, and the cable is removed from the riveting station. Then the clamp 20 is released, completing the entire process of cutting, stripping and riveting a photovoltaic connector.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
