Description

Technical Field

[0001] This invention relates to the field of photovoltaic cable processing technology, and more specifically to a precision cutting device and cutting method for photovoltaic cable processing. Background Technology

[0002] Photovoltaic cables are key conductive components in photovoltaic power generation systems, used to connect photovoltaic modules, inverters, and power distribution equipment. They are exposed to harsh outdoor environments such as high temperatures, ultraviolet radiation, humidity, and mechanical stress for extended periods. Therefore, they typically employ a multi-layered composite structure design: the inner layer is a high-purity tin-plated copper conductor, while the outer layer is wrapped with highly flexible, weather-resistant insulation and sheathing materials such as cross-linked polyolefin (XLPO) or thermoplastic elastomer (TPE). These materials give photovoltaic cables excellent anti-aging and bending properties, but also make them significantly soft, easily deformable, and prone to springback.

[0003] In actual production, photovoltaic cables need to be cut to specific lengths according to project requirements. Existing equipment mostly relies on manual labor and manual tightening, which is inefficient and inconsistent, making it difficult to meet the needs of large-scale and high-speed production in the photovoltaic industry.

[0011] Preferably, a first slide groove and a second slide groove are provided at the upper end of the placement rack.

[0012] Preferably, a guide plate is fixedly connected to the lower end of the cable management plate via a connecting plate. The guide plate is slidably connected along a groove provided at the upper end of the base. Two push columns are fixedly provided on the guide plate. The push columns are symmetrically arranged and are semi-T-shaped, with their protruding ends extending toward the fixing device.

[0013] Preferably, a plurality of rollers are evenly arranged at the rear end of the placement frame, and a guide plate is provided at the front end of the rollers. The guide plate has a guide groove corresponding to the photovoltaic cable and a notch at the front end of the guide plate. A collection box is provided at the upper end of the base, and an electric slide rail is provided at the bottom of the collection box. The electric slide rail is fixedly connected to the bottom of the sliding frame through a fixed seat. A second cylinder is also fixedly provided at the upper end of the sliding frame, and a mounting plate is also fixedly provided at the output end of the second cylinder. A clamping device corresponding to the feed hole is also provided at the front end of the mounting plate. A second gantry frame is also provided at the upper end of the placement frame, and a third cylinder is fixedly provided at the upper end of the second gantry frame. The output end of the third cylinder passes through the upper end of the second gantry frame and is connected to the upper end of the second gantry frame through a bearing. A push plate is fixedly provided at the output end of the third cylinder, and a notch corresponding to the photovoltaic cable is provided at the bottom of the push plate.

[0014] A precision cutting method for photovoltaic cable processing includes the following steps: Step 1: First, pass the photovoltaic cable to be cut through the feed hole, the through groove inside the cable management plate, the gap between the pressure plate and the support frame, and the through groove formed between the positioning ring and the pad. Finally, let the front end of the photovoltaic cable hang down naturally to the bottom of the placement frame in a vertical state.

[0015] Step 2: Then control the electric slide rail to move forward, driving the sliding frame to move forward as a whole. Its front end slides along the first slide groove and its rear end slides along the second slide groove, maintaining a stable posture. At this time, the front end of the sliding frame drives the mounting plate to move forward synchronously, so that the clamping device at the top moves to the front of the photovoltaic cable.

[0016] Step 3: Next, control the first cylinder to retract, drive the clamping plate to move backward, cooperate with the front positioning block, clamp the vertically downward photovoltaic cable front end between the two grooves. After clamping is completed, control the electric slide rail to move backward in the opposite direction, and the clamping device pulls the photovoltaic cable backward to the preset cutting position.

[0017] Step 4: When the sliding frame continues to move backward to the cutting station, the push frame at its rear end contacts and acts on the fixed column, pushing the positioning sleeve to move along the inclined Z-shaped slide. Since the positioning column is embedded in the inclined Z-shaped slide and is constrained by its trajectory, the pad plate initially maintains an inclined posture and is parallel to the inclined side of the slide. When the positioning column moves to the bottom horizontal section of the inclined Z-shaped slide, the pad plate turns to a horizontal state and is parallel to the positioning plate, forming a flat and aligned cutting groove between the two. At the same time, the backward movement of the wire guide plate drives the guide plate to move synchronously, causing the push column to move forward and contact the force-bearing surface of the inclined push plate.

[0018] Step 5: As the push column continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate, forcing the inclined push plate to rotate around the rotating axis, which in turn drives the rotating wheel to rotate. The rotation of the rotating wheel causes the connecting column to slide along the arc-shaped groove from the initial front horizontal section through the arc section into the rear horizontal section, pulling the guide column downward, thereby driving the pressure plate to press down and firmly clamp the photovoltaic cables on the support frame.

[0019] Step 6: At this point, the photovoltaic cable has been fixed at both ends. Then, the hydraulic cylinder is extended to drive the cutting blade to fall vertically, making a clean and burr-free, precise cut to the photovoltaic cable. After the cut is completed, the front end of the photovoltaic cable becomes a free end. The sliding frame moves backward again. When it moves to a certain position, the third cylinder is activated to push the pressure plate down and press the free end into the notch. Then, the second cylinder is extended so that the clamping device at its front end clamps the cut cable segment located in the notch.

[0020] Step 7: Next, control the electric slide rail to move forward. The clamping device at the front end of the second cylinder will pull the cut photovoltaic cable out from the notch and send it into the collection box. At this time, the uncut main section between the pressure plate and the support frame is still clamped to ensure stable subsequent feeding.

[0021] Step 8: Subsequently, the cable management plate moves forward with the sliding frame. During this process, the newly entered photovoltaic cables are actively managed and centered. When the front push column moves forward, the front moving column advances forward and contacts the force-bearing surface of the inclined push plate. As the front push column continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate, forcing the inclined push plate to rotate around the rotating axis, thereby driving the rotating wheel to rotate. This causes the connecting column to slide along the arc-shaped slide groove from the rear horizontal section to the arc section and the front horizontal section, ultimately driving the pressure plate to rise and automatically release the photovoltaic cables on the support frame. At the same time, the pad rises along the inclined Z-shaped slide groove under the action of the spring's restoring force, returning to the initial high horizontal state, preparing for the next cutting cycle.

[0022] Beneficial Effects: Compared with existing technologies, this invention, through the coordinated control of the front-end clamping device and the rear-end fixing device, simultaneously clamps the flexible photovoltaic cable on both sides of the cutting area, completely eliminating slippage, springback, or vibration caused by the softness of the material, ensuring precise cutting position and a smooth cut. The pad plate, through the cooperation of the inclined Z-shaped groove and the positioning post, automatically sinks before cutting and forms a flat cutting groove with the positioning plate, providing clearance for the cutting blade, avoiding collision between the blade and the hard support surface, and ensuring that the flexible cable is completely cut without pulling. Through the coordinated action of the third cylinder, the push plate, the notch, and the clamping device at the front end of the second cylinder, the finished product segment is automatically pressed in, clamped, and fed into the collection box, significantly improving the level of automation and production efficiency.

Detailed Implementation

[0024] Next, we will combine the appendix Figures 1-8 A specific embodiment of the present invention will be described in detail below.

[0025] As attached Figure 1 The diagram shows a precision cutting device for photovoltaic cables, comprising a base 1, a placement frame 2 at the upper end of the base 1, and a cutting device 3 in the middle of the placement frame 2. The cutting device 3 is used to cut photovoltaic cables. The cutting device 3 includes a first gantry frame 31 fixed to the upper end of the base 1, with a hydraulic cylinder 32 fixed to the upper end of the first gantry frame 31. The hydraulic cylinder 32 is vertically installed, its axis aligned with the cutting area of ​​the placement frame 2. The output end of the hydraulic cylinder 32 passes through and is connected to the top of the first gantry frame 31 via a bearing. A cutting blade 33 is fixed to the output end of the hydraulic cylinder 32. The cutting blade 33 is made of high-hardness alloy steel, with a sharp and wear-resistant cutting edge, suitable for multi-layer composite photovoltaic cables. The photovoltaic cable below the cutting blade 33 is cut by controlling the extension and retraction of the hydraulic cylinder 32.

[0026] As attached Figure 2 As shown: Multiple feed holes 4 are evenly provided on one side of the placement rack 2. The diameter of the feed holes 4 is larger than the diameter of the photovoltaic cable. That is, the photovoltaic cable enters the upper end of the placement rack 2 through the feed holes 4. The placement rack 2 is provided with a mounting plate 5. The front end of the mounting plate 5 is evenly provided with clamping devices 6 corresponding to the feed holes 4 to ensure that each photovoltaic cable can be independently positioned. The clamping device 6 is used to clamp the front end of the photovoltaic cable that enters through the feed holes 4.

[0027] A pad 7 is provided at the upper end of the placement rack 2. The pad 7 is parallel to the placement rack 2. The pad 7 is provided with a positioning ring 8 corresponding to the feed hole 4. A through groove is formed between the positioning ring 8 and the pad 7. That is, after the photovoltaic cable enters through the feed hole 4, it enters the through groove at the upper end of the pad 7 and then falls vertically. The clamping device 6 clamps the end of the photovoltaic cable. Then, by moving the mounting plate 5, the clamping device 6 moves the photovoltaic cable to the designated position, and the cutting device 4 cuts the photovoltaic cable.

[0028] A positioning plate 9 is provided at the lower end of the cutting device 4. The positioning plate 9 is fixedly connected to the placement frame 2. That is, when the pad 7 moves to the lower end of the cutting device 4, a cutting groove is formed between the pad 7 and the positioning plate 9 to ensure that the cutting blade 33 has clearance when it falls and to completely cut the photovoltaic cable.

[0029] As attached Figure 8 As shown above, a groove is formed between the pad 7 and the positioning plate 9 to ensure that the cutting blade 33 has clearance when it falls and can completely cut the photovoltaic cable. To achieve this function, the pad 7 needs to be moved. That is, two positioning posts 11 are provided at both ends of the pad 7, and a slanted Z-shaped slide 12 is provided in the middle of the placement frame 2. The slanted Z-shaped slide 12 includes an upper horizontal section, an inclined transition section and a lower horizontal section. A positioning sleeve 13 is fitted on the outside of the positioning posts 11. The positioning sleeve 13 is located on the outside of the placement frame 2, and a fixing post 15 is fixed on one side of the positioning sleeve 13. The positioning posts 11 and the positioning sleeve 13 are rotatably connected, so that the pad 7 can automatically adjust its posture according to the slide trajectory during the movement.

[0030] As attached Figure 1 As shown: A sliding frame 10 is provided at the lower end of the placement frame 2, and a pusher frame 14 is fixedly provided at the rear end of the sliding frame 10. The front end of the sliding frame 10 is connected to the mounting plate 5 through a sliding column, which is used to drive the clamping device 6 and the photovoltaic cable to be horizontally moved to the cutting station. That is, by moving the sliding frame 10, its front end first drives the mounting plate 5 to move a certain distance, completing the precise positioning of the cable. Subsequently, the pusher frame 14 continues to move forward and acts on the fixed column 15, thereby pushing the positioning sleeve 13 along the direction of the inclined Z-shaped slide groove 12 to drive the pad 7 to move synchronously. Since the positioning column 11 is embedded in the inclined Z-shaped slide groove 12 and constrained by it, the pad 7 maintains an inclined posture and is parallel to the inclined side in the initial stage. When the positioning column 11 runs to the bottom horizontal section of the inclined Z-shaped slide groove 12, the pad 7 turns to a horizontal state, parallel to the positioning plate 9, and forms a flat and aligned cutting groove below it, for the cutting blade 33 to cut vertically, ensuring that the photovoltaic cable is cut completely and without pulling.

[0031] In this application, springs 17 are provided on both sides of the placement frame 2. One end of the spring 17 is fixedly connected to the fixing post 15, and the other end is fixedly connected to the mounting post 18 fixed on the side of the placement frame 2, so as to facilitate the repositioning of the pad 7.

[0032] As is common sense, when cutting photovoltaic cables, it is necessary to reliably fix the cables on both sides of the cutting area to prevent uneven cuts or equipment damage caused by cable springback, slippage or vibration during the cutting process.

[0033] As attached Figure 7 As shown: A fixing device 16 is also provided on one side of the placement frame 2 for clamping the photovoltaic cable upstream of the cutting point. The fixing device 16 includes a support frame 1601 fixedly connected to the base 1. The upper end of the support frame 1601 is provided with a positioning groove that matches the outer diameter of the photovoltaic cable for supporting and initially limiting the cable. Two guide columns 1602 are slidably connected on both sides of the support frame 1601. The guide columns 1602 can move up and down in the vertical direction. A pressure plate 1603 is fixedly connected to the top of the guide column 1602. The photovoltaic cable is located between the pressure plate 1603 and the top of the support frame 1601. That is, when the pressure plate 1603 moves downward, it will press the photovoltaic cable at the upper end of the support frame 1601 into the positioning groove to achieve stable clamping.

[0034] To drive the pressure plate 1603 to move downward, two fixing plates 1604 are provided at the lower end of the guide post 1602. The fixing plates 1604 are fixedly connected to the top of the base 1. A rotating shaft 1605 is provided between the two fixing plates 1604. Both ends of the rotating shaft 1605 are rotatably connected to the fixing plates 1604 through bearings to ensure smooth rotation. A rotating wheel 1606 is fixedly provided on the rotating shaft 1605. The rotating wheel 1606 rotates synchronously with the rotating shaft 1605. An arc-shaped groove 1607 is provided on the rotating wheel 1606. It should be noted that the two ends of the arc-shaped groove 1607 are horizontal, and the middle section is a rounded transition.

[0035] A connecting post 1608 is provided at the lower end of the guide post 1602. The lower end of the connecting post 1608 has a hollow structure and is sleeved on the arc-shaped slide groove 1607 so that it can slide along the slide groove trajectory. An inclined push plate 1609 is also fixed on the rotating shaft 1605.

[0036] In the initial state, the connecting post 1608 is located at the front horizontal section of the arc-shaped slide 1607, the pressure plate 1603 is in a high position, and the cable can freely pass through the positioning slot of the support frame 1601. By rotating the inclined push plate 1609, the rotating shaft 1605 and the rotating wheel 1606 are driven to rotate synchronously, so that the connecting post 1608 slides along the arc-shaped slide 1607 from the horizontal section through the arc section into the rear horizontal section, thereby pulling the guide post 1602 to move downward. The downward movement of the guide post 1602 causes the pressure plate 1603 to press the photovoltaic cable, thereby achieving reliable fixation of the cable before cutting and ensuring that the cutting process is stable, accurate and without displacement.

[0037] As attached Figure 6 and Figure 8 As shown above, the pad 7 is reset by the spring 17. Since the pad 7 rises along the inclined Z-shaped slide 12 and eventually returns to the initial high position and is in a horizontal state, the clamping device 6 at the front end has been released. Under its own weight or slight rebound, the front end of the photovoltaic cable will naturally droop or be in an unconstrained state. In order to facilitate the clamping device 6 to perform reliable and repeated clamping operations on the photovoltaic cable, the clamping device 6 includes a base 61 fixedly connected to the mounting plate 5. Two positioning blocks 62 are fixedly provided on the base 61. The two positioning blocks 62 are arranged one in front of the other to form a stable clamping range. A first cylinder 63 is fixedly provided on the rear side of the front positioning block 62. The output shaft of the first cylinder 63 extends horizontally toward the rear positioning block 62. A clamping plate 64 is fixedly provided at the front end of the output shaft of the first cylinder 63. The clamping plate 64 is at the front end of the rear positioning block 62.

[0038] The inner side of the clamping plate 64 and one side of the positioning block 62 at the front end are provided with grooves 65 that match the outer diameter of the photovoltaic cable. The two grooves 65 face each other to form a circular or near-circular clamping hole. The grooves 65 are provided with threaded grooves or anti-slip textures to increase the coefficient of friction and prevent the cable from axially slipping during the cutting process, thereby ensuring that each clamping is firm and the positioning is accurate, providing a prerequisite guarantee for high-precision fixed-length cutting.

[0039] As attached Figure 1 As shown: A first slide groove 19 and a second slide groove 20 are provided at the upper end of the placement frame 2. The height of the second slide groove 20 is higher than the height of the first slide groove 19, forming a stepped double-layer guide rail structure. The first slide groove 19 is slidably connected to the front end of the sliding frame 10 through a sliding column, and the second slide groove 20 is also slidably connected to the rear end of the sliding frame 10 through a sliding column, so that the sliding frame 10 maintains a horizontal posture and runs smoothly during movement.

[0040] As attached Figure 5As shown: The sliding column at the rear end of the sliding frame 10 is fixedly connected to the cable management plate 21 located in the placement frame 2, ensuring that the cable management plate 21 moves synchronously with the sliding frame 10. The cable management plate 21 has a through hole inside, the diameter of which is larger than the diameter of the photovoltaic cable, to guide the cable to pass smoothly without scratching or deflection. That is, the photovoltaic cable first enters the placement frame 2 through the feeding hole 4, then passes through the through hole inside the cable management plate 21 for initial guidance and centering, and then enters the through groove formed between the positioning ring 8 and the pad 7. Finally, it is clamped by the clamping device 6, thereby realizing precise guidance and stable constraint of the entire process from feeding to positioning and clamping.

[0041] As attached Figure 5 As shown: The guide plate 23 is fixedly connected to the lower end of the cable management plate 21 by a connecting plate 22. The guide plate 23 is slidably connected along the sliding groove provided at the upper end of the base 1 to ensure that its movement trajectory is synchronized and stable with the cable management plate 21. Two push columns 24 are fixedly provided on the guide plate 23. The push columns 24 are symmetrically arranged and are semi-T-shaped, with their protruding ends extending toward the fixing device 16.

[0042] When the cable management plate 21 moves forward with the sliding frame 10, it will drive the guide plate 23 to move forward synchronously, thereby causing the rear push column 24 to move forward and contact the force-bearing surface of the inclined push plate 1609. As the rear push column 24 continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate 1609, forcing the inclined push plate 1609 to rotate around the rotating axis 1605, thereby driving the rotating wheel 1606 to rotate, causing the connecting column 1608 to slide along the arc-shaped slide groove 1607 from the front horizontal section to the arc section and the rear horizontal section, and finally driving the pressure plate 1603 to press down, realizing the automatic clamping of the photovoltaic cables on the support frame 1601. Since the rear end is horizontal, the clamping is maintained.

[0043] When the front push column 24 moves backward, the front moving column 24 pushes backward and contacts the force-bearing surface of the inclined push plate 1609. As the front push column 24 continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate 1609, forcing the inclined push plate 1609 to rotate around the rotating shaft 1605, thereby driving the rotating wheel 1606 to rotate, causing the connecting column 1608 to slide along the arc-shaped slide groove 1607 from the rear horizontal section to the arc section and the front horizontal section, ultimately driving the pressure plate 1603 to rise, realizing the automatic release of the photovoltaic cable on the support frame 1601. Since the front end is horizontal, the release is maintained.

[0044] As attached Figure 1 and Figure 5As shown: After cutting, the photovoltaic cables need to be collected. Multiple rollers 25 are evenly arranged at the rear end of the placement rack 2. A guide plate 26 is provided at the front end of each roller 25. The guide plate 26 has guide grooves corresponding to the photovoltaic cables. A notch 27 is provided at the front end of the guide plate 26. A collection box 36 is provided at the upper end of the base 1. An electric slide rail is provided at the bottom of the collection box 36. The electric slide rail is fixedly connected to the bottom of the sliding frame 10 through a fixed seat. Driving the electric slide rail causes the sliding frame 10 to reciprocate. A second cylinder 28 is also fixedly provided at the lower end of the sliding frame 10. A mounting plate 5 is also fixedly provided at the output end of the second cylinder 28. A clamping device 6 corresponding to the feed hole 4 is also provided at the front end of the mounting plate 5. A second gantry 29 is also provided at the upper end of the placement rack 2. A third cylinder 30 is fixedly provided at the upper end of the second gantry 29. The output end of the third cylinder 30 passes through the upper end of the second gantry 29 and is connected to the upper end of the second gantry 29 through a bearing. A push plate 34 is fixedly provided at the output end of the third cylinder 30. A notch 35 corresponding to the photovoltaic cable is provided at the bottom of the push plate 34.

[0045] A precision cutting method for photovoltaic cable processing includes the following steps: Step 1: First, pass the photovoltaic cable to be cut through the feed hole 4, the through groove inside the cable management plate 21, the gap between the pressure plate 1603 and the support frame 1601, and the through groove formed between the positioning ring 8 and the pad 7. Finally, let the front end of the photovoltaic cable hang down naturally to the bottom of the placement frame 2 in a vertical state.

[0046] Step 2: Then control the electric slide rail to move forward, driving the sliding frame 10 to move forward as a whole. Its front end slides along the first slide groove 19 and its rear end slides along the second slide groove 20, maintaining a stable posture. At this time, the front end of the sliding frame 10 drives the mounting plate 5 to move forward synchronously, so that the clamping device 6 at the upper end moves to the front of the photovoltaic cable.

[0047] Step 3: Next, control the first cylinder 63 to retract, drive the clamping plate 64 to move backward, cooperate with the front positioning block 62, clamp the vertically downward photovoltaic cable front end between the two grooves 65. After clamping, control the electric slide rail to move backward in the opposite direction, and the clamping device 6 pulls the photovoltaic cable backward to the preset cutting position. During this process, the cable management plate 21 moves backward synchronously with the sliding frame 10, and its moving speed is consistent with that of the photovoltaic cable. Therefore, it does not generate additional friction or pulling on the cable, but only plays a guiding role.

[0048] Step 4: When the sliding frame 10 continues to move backward to the cutting station, the push frame 14 at its rear end contacts and acts on the fixed column 15, pushing the positioning sleeve 13 to move along the inclined Z-shaped slide 12. Since the positioning column 11 is embedded in the inclined Z-shaped slide 12 and is constrained by its trajectory, the pad 7 initially maintains an inclined posture and is parallel to the inclined side of the slide. When the positioning column 11 moves to the bottom horizontal section of the inclined Z-shaped slide 12, the pad 7 turns to a horizontal state and is parallel to the positioning plate 9, forming a flat and aligned cutting groove between the two. At the same time, the backward movement of the wire guide plate 21 drives the guide plate 23 to move synchronously, causing the push column 24 to move forward and contact the force-bearing surface of the inclined push plate 1609.

[0049] Step 5: As the push column 24 continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate 1609, forcing the inclined push plate 1609 to rotate around the rotating shaft 1605, which in turn drives the rotating wheel 1606 to rotate. The rotation of the rotating wheel 1606 causes the connecting column 1608 to slide along the arc-shaped slide groove 1607 from the initial front horizontal section through the arc section into the rear horizontal section, pulling the guide column 1602 to move downward, thereby driving the pressure plate 1603 to press down and firmly clamp the photovoltaic cable on the support frame 1601.

[0050] Step 6: At this point, the photovoltaic cable has been fixed at both ends. Then, the hydraulic cylinder 32 is extended to drive the cutting blade 33 to fall vertically, making a clean and burr-free precise cut on the photovoltaic cable. After the cut is completed, the front end of the photovoltaic cable becomes a free end. The sliding frame 10 moves backward again. When it moves to a certain position, the third cylinder 30 is activated to push the pressing plate 31 down and press the free end into the notch 27. Then, the second cylinder 28 is extended so that the clamping device 4 at its front end clamps the cut cable segment located in the notch 27.

[0051] Step 7: Next, control the electric slide rail to move forward. The clamping device 4 at the front end of the second cylinder 28 pulls the cut photovoltaic cable out from the notch 27 and into the collection box 36. It should be noted that when the upper clamping device 6 moves to the front end of the notch 27, control the first cylinder 63 to extend, causing the clamping plate 64 to release the original cable, so that the clamping device 4 at the front end of the second cylinder 28 can smoothly take over and pull away the finished section. At this time, the uncut main section between the pressure plate 1603 and the support frame 1601 is still clamped, ensuring stable subsequent feeding. It should be noted that, as shown in the attached... Figure 1 Moving forward as shown indicates moving from left to right.

[0052] Step 8: Subsequently, the cable management plate 21 moves forward with the sliding frame 10. During this process, the newly entered photovoltaic cables are actively managed and centered. When the front push column 24 moves forward, the front moving column 24 advances forward and contacts the force-bearing surface of the inclined push plate 1609. As the front push column 24 continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate 1609, forcing the inclined push plate 1609 to rotate around the rotating axis 1605, thereby driving the rotating wheel 1606 to rotate, causing the connecting column 1608 to slide along the arc-shaped slide groove 1607 from the rear horizontal section to the arc section and the front horizontal section, ultimately driving the pressure plate 1603 to rise, realizing the automatic release of the photovoltaic cables on the support frame 1601. At the same time, the pad 7 rises along the inclined Z-shaped slide groove 12 under the action of the spring 17, returning to the initial high horizontal state, preparing for the next cutting cycle.

10. The precision cutting device for photovoltaic cable processing according to claim 1, characterized in that: A precision cutting method for photovoltaic cable processing includes the following steps: Step 1: First, pass the photovoltaic cable to be cut through the feed hole (4), the through groove inside the cable management plate (21), the gap between the pressure plate (1603) and the support frame (1601), and the through groove formed between the positioning ring (8) and the pad (7) in sequence. Finally, let the front end of the photovoltaic cable hang down naturally to the bottom of the placement rack (2) in a vertical state. Step 2: Then control the electric slide rail to move forward, driving the sliding frame (10) to move forward as a whole. Its front end slides along the first slide groove (19), and its rear end slides along the second slide groove (20) to maintain a stable posture. At this time, the front end of the sliding frame (10) drives the mounting plate (5) to move forward synchronously, so that the clamping device (6) at the top moves to the front of the photovoltaic cable. Third step: Next, control the first cylinder (63) to retract, drive the clamping plate (64) to move backward, cooperate with the front positioning block (62), clamp the vertically downward photovoltaic cable front end between the two grooves (65), after clamping is completed, control the electric slide rail to move backward in the opposite direction, and the clamping device (6) pulls the photovoltaic cable backward to the preset cutting position. Step 4: When the sliding frame (10) continues to move backward to the cutting station, the push frame (14) at its rear end contacts and acts on the fixed column (15), pushing the positioning sleeve (13) to move along the inclined Z-shaped slide (12). Since the positioning column (11) is embedded in the inclined Z-shaped slide (12) and constrained by its trajectory, the pad (7) initially maintains an inclined posture and is parallel to the inclined side of the slide. When the positioning column (11) runs to the bottom horizontal section of the inclined Z-shaped slide (12), the pad (7) turns to a horizontal state and is parallel to the positioning plate (9), forming a flat and aligned cutting groove between the two. At the same time, the backward movement of the wire guide plate (21) drives the guide plate (23) to move synchronously, causing the push column (24) to move forward and contact the force-bearing surface of the inclined push plate (1609). Step 5: As the push column (24) continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate (1609), forcing the inclined push plate (1609) to rotate around the rotating axis (1605), which in turn drives the rotating wheel (1606) to rotate. The rotation of the rotating wheel (1606) causes the connecting column (1608) to slide along the arc-shaped slide groove (1607) from the initial front horizontal section through the arc section into the rear horizontal section, pulling the guide column (1602) to move downward, thereby driving the pressure plate (1603) to press down and firmly clamp the photovoltaic cable on the support frame (1601). Step 6: At this time, the photovoltaic cable has been fixed at both ends. Then, the hydraulic cylinder (32) is extended and the cutting blade (33) is driven to fall vertically to cleanly and precisely cut the photovoltaic cable without burrs. After the cutting is completed, the front end of the photovoltaic cable becomes the free end. The sliding frame (10) moves backward again. When it moves to a certain position, the third cylinder (30) is started to push the push plate (34) down and press the free end into the notch (27). Then, the second cylinder (28) is extended so that the clamping device (4) at its front end clamps the cut cable segment located in the notch (27). Step 7: Next, control the electric slide rail to move forward, and the clamping device (4) at the front end of the second cylinder (28) will pull the cut photovoltaic cable out from the notch (27) and send it into the collection box (36). At this time, the uncut main section between the pressure plate (1603) and the support frame (1601) is still clamped to ensure stable subsequent feeding. Step 8: Subsequently, the cable management plate (21) moves forward with the sliding frame (10). During this process, the newly entered photovoltaic cables are actively managed and aligned. When the front end push column (24) moves forward, the front end moving column (24) advances forward and contacts the force-bearing surface of the inclined push plate (1609). As the front end push column (24) continues to move forward, its semi-T-shaped structure applies a pushing force to the inclined push plate (1609), forcing the inclined push plate (1609) to rotate around the rotation axis (1605). The rotation of the wheel (1606) drives the rotating wheel (1606) to rotate, causing the connecting column (1608) to slide along the arc-shaped slide (1607) from the rear horizontal section to the arc section and the front horizontal section, and finally drive the pressure plate (1603) to rise, so as to automatically release the photovoltaic cable on the support frame (1601). At the same time, the pad (7) rises along the inclined Z-shaped slide (12) under the restoring force of the spring (17) and returns to the initial high horizontal state, preparing for the next cutting cycle.
