Description

Technical Field

[0001] This invention relates to the field of converter wire bending device technology, and particularly to a photovoltaic quad-commensurable converter wire bending and forming device. Background Technology

[0002] As a core component for protocol conversion and data transmission in photovoltaic systems, the bending precision of the internal copper wires in photovoltaic (PV) converters directly affects the operational stability of the equipment. These converters typically require copper wires to be bent into L- or U-shapes to fit the compact internal space, and the cutting process must be completed simultaneously during continuous bending. Existing bending and forming devices mostly use shearing methods to process the wires. Because the shearing force is applied instantaneously to the copper wire, defects such as burrs and collapsed edges appear on the cut end face. Burrs may detach and cause short circuits, and uneven end faces can affect connection stability, reduce the signal transmission accuracy and lifespan of the converter, and sharp burrs can easily cut hands when handled, making it difficult to meet the actual high-precision processing requirements of photovoltaic equipment.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The copper wire is passed through two sets of conveyor wheels, a fixed plate, and inside the cylinder. The motor drives the synchronous wheel to rotate, and the synchronous belt drives another set of synchronous wheels and a connected set of conveyor wheels and gears to rotate. The two sets of meshing gears drive another set of gears and conveyor wheels to rotate, conveying the clamped copper wire to the inside of the cylinder, continuously providing material for bending. The continuous bending and cutting process realizes batch standardized production.

[0015] 2. When the copper wire passes through the cylinder to the upper side of the second frame on one side, the third motor drives the fourth synchronous pulley to rotate. The third synchronous belt drives another set of fourth synchronous pulleys to rotate the second gear. The rotating second gear drives the half gear on one side to rotate on the outside of the cylinder. The rotating half gear drives the fixed bar and the bending shaft to rotate in the movable opening. The rotation of the bending shaft can bend the copper wire extending from the cylinder. The fourth motor drives the third gear to rotate, driving the meshing bending shaft to slide between the two sets of fixed bars, so that the bending shaft retracts to the inside of the half gear. At this time, by driving the half gear, the bending shaft can be moved to the upper or lower side of the copper wire, and then extended for bending. This realizes different bending operations and flexibly adapts to the various bending requirements such as L-shaped and U-shaped inside the converter.

[0016] 3. The motor drives the gear four to rotate, which in turn drives the meshing gear five. Two sets of drive ports drive two sets of shafts, cutters, and connecting rods to move closer together. The connecting rods slide in the guide port, pushing the hollow plate and grinding sleeve to move backward. After moving out of the cutting position, the two sets of cutters quickly cut the copper wire, realizing continuous and rapid cutting work, which can bring significant production and quality advantages.

[0017] 4. After the two sets of cutters unfold, the two sets of connecting rods drive the hollow plate forward through the guide port, moving the grinding cylinder sleeve to the position where the copper wire is cut. At the same time, the moved positioning rod presses and fixes the cut section of copper wire, compressing the spring. Motor 2 drives synchronous wheel 3 to rotate, synchronous wheel 3 drives synchronous belt 2 to rotate, and synchronous belt 2 drives synchronous wheel 2 and the inner grinding cylinder sleeve to rotate rapidly. At this time, the copper wire is driven to press against one end of the grinding cylinder sleeve through the two sets of conveying wheels, pushing the slide bar on the grinding cylinder sleeve to slide along the slide groove, compressing the spring. The other side of the grinding cylinder sleeve contacts the end face of the fixed section of copper wire. The rapidly rotating grinding cylinder sleeve grinds the end face of the copper wire, specifically solving the problem of cut end face defects, eliminating burrs, collapsed edges and other protrusions, making the end face flat and smooth, and avoiding personnel being scratched by sharp burrs when handling it.

The end face processing component 3 includes a cylinder 31 fixedly set at the center position of the mounting frame 1, a movable cavity 32 opened on the inner side of the cylinder 31, a square cavity 33 opened at the center position of the cylinder 31, a hollow plate 34 slidably arranged inside the movable cavity 32, guide openings 35 opened on both the upper and lower sides of the hollow plate 34, and a fixing strip 36 fixedly set at the middle position of one end of the hollow plate 34. A positioning rod 37 is slidably arranged on the outer side of the 36. A spring 38 is fixedly arranged between the front end of the fixing strip 36 and the inner wall of the positioning rod 37. Two sets of fixing rings 39 are fixedly arranged on the front end of the hollow plate 34. A synchronous wheel 310 is rotatably arranged on the inner side of the two sets of fixing rings 39. Several sets of sliding grooves 311 are opened on the inner wall of the synchronous wheel 310. A grinding sleeve 312 is movably arranged on the inner side of the synchronous wheel 310. Several sets of sliding strips 313 are fixedly arranged on the outer side of the grinding sleeve 312. A spring piece 314 is fixedly arranged on one end of the hollow plate 34 near the grinding sleeve 312. A frame 315 is fixedly arranged at the rear end of the cylinder 31. A motor 316 is fixedly arranged at one end of the frame 315. A synchronous wheel 317 is fixedly arranged on the rotating shaft of the motor 316. A synchronous belt 318 is sleeved on the outer side of the synchronous wheel 317 and the synchronous wheel 310.

[0032] Copper wire 6 passes between two sets of conveyor wheels 23 and inside the fixed plate 21 and cylinder 31. Cylinder 31 is fixedly connected to mounting bracket 1 by bolts. Inside cylinder 31, a conveying port is provided corresponding to the position of copper wire 6. Square cavity 33 corresponds to the position where copper wire 6 passes through. Hollow plate 34 is slidably set in the middle of the inner side of movable cavity 32. Spring 38 is in a compressed state. Grinding sleeve 312 corresponds to the position of copper wire 6. Both sides of grinding sleeve 312 are arc end faces. Sliding bar 313 slides to one side inside sliding groove 311. Spring piece 314 covers one side of sliding bar 313. Synchronous belt 2 318 passes through the inner side of hollow plate 34.

[0033] After the two sets of cutters 57 have cut and unfolded, the two sets of connecting rods 58 drive the hollow plate 34 forward through the guide port 35, causing the grinding sleeve 312 to move to the position where the copper wire 6 is cut. At the same time, the moved positioning rod 37 presses and fixes the cut section of copper wire 6, compressing the spring 38. The motor 2 316 drives the synchronous pulley 317 to rotate, which in turn drives the synchronous belt 2 318 to rotate. The synchronous belt 2 318 then drives the synchronous pulley 2 310 to engage with the inner grinding sleeve 312. The copper wire 6 is driven to press against one end of the grinding sleeve 312 by two sets of conveying wheels 23. This pushes the slide bar 313 on the grinding sleeve 312 to slide along the slide groove 311, squeezing the spring piece 314. Meanwhile, the other side of the grinding sleeve 312 contacts the end face of the copper wire 6 that is held and fixed. The rapidly rotating grinding sleeve 312 grinds the end face of the copper wire 6, specifically solving the problem of cutting end face defects, eliminating burrs, collapsed edges and other protrusions, making the end face flat and smooth, and preventing personnel from being scratched by sharp burrs when handling it.

[0034] The conveying assembly 2 includes a fixed plate 21 fixedly mounted on one side of the front end of the mounting frame 1. A wheel frame 22 is fixedly mounted on one side of the fixed plate 21.

A motor 25 is fixedly mounted on the rear side of the mounting frame 1. Synchronous pulleys 26 are fixedly mounted on the rotating shafts of the motor 25 and the rotating shafts of the two sets of conveying wheels 23. Synchronous belts 27 are sleeved on the outer sides of the two sets of synchronous pulleys 26.

[0035] The fixed plate 21 is provided with a second conveying port corresponding to the position of the copper wire 6. Two sets of conveying wheels 23 clamp the copper wire 6 and rotate it for conveying. Two sets of gears 24 are meshed together.

[0036] The copper wire 6 is passed through two sets of conveyor wheels 23, a fixed plate 21, and the inside of the cylinder 31. The synchronous wheel 26 is rotated by the motor 25. The synchronous belt 27 drives another set of synchronous wheels 26 to rotate with a connected set of conveyor wheels 23 and gears 24. The two sets of meshing gears 24 drive another set of gears 24 and conveyor wheels 23 to rotate, thus conveying the clamped copper wire 6 to the inside of the cylinder 31. This continuously provides material for bending, and the continuous bending and cutting process enables standardized mass production.

[0037] The bending assembly 4 includes a motor 41 fixedly mounted on the rear side of the mounting frame 1 away from the motor 25.

A motor 410 is fixedly mounted on the upper end of the frame 47. An opening 411 is provided on the inner side of the mounting frame 1 along the rotation path of the fixing rods 46 and the bending shaft 48.

[0038] Gear 2 42 meshes with half gear 45. Half gear 45 passes through movable port 411 and is connected to half gear 45. Fixed rod 46 and bending shaft 48 are adapted to movable port 411.

Gear 3 49 is fixedly connected to the rotating shaft of motor 410.

[0039] When the copper wire 6 passes through the cylinder 31 to the upper side of the frame 47, the synchronous pulley 43 is rotated by the motor 41. The synchronous belt 44 drives another set of synchronous pulleys 43 to rotate simultaneously. The rotating gear 42 drives the half gear 45 on one side to rotate outside the cylinder 31. The rotating half gear 45 drives the fixed rod 46 and the bending shaft 48 to rotate in the movable opening 411. The rotation of the bending shaft 48 can bend the copper wire 6 extending from the cylinder 31. The motor 410 drives the gear 49 to rotate, driving the bent shaft 48 to slide between the two sets of fixed rods 46, so that the bending shaft 48 retracts to the inside of the half gear 45. At this time, by driving the half gear 45, the bending shaft 48 can be moved to the upper or lower side of the copper wire 6, and then extended for bending. This realizes different bending operations and flexibly adapts to the various bending requirements such as L-shaped and U-shaped inside the converter.

[0040] The cutting assembly 5 includes a frame 3 51 fixedly mounted on a set of wheel frames 22 on the front side. A motor 52 is fixedly mounted at the front end of the frame 3 51.

[0042] Motor 52 drives gear 4 53 to rotate, which in turn drives meshing gear 54. Two sets of drive ports 55 drive two sets of shafts 56, cutters 57, and connecting rods 58 to move closer together. The connecting rods 58 slide in the guide port 35, pushing the hollow plate 34 and grinding sleeve 312 to move backward. After moving out of the cutting position, the two sets of cutters 57 quickly cut the copper wire 6, realizing continuous and rapid cutting work, which can bring significant production and quality advantages.

[0043] Working principle: In use, the copper wire 6 is passed through two sets of conveyor wheels 23, the fixed plate 21, and the inside of the cylinder 31. The motor 25 drives the synchronous pulley 26 to rotate, and the synchronous belt 27 drives another set of synchronous pulleys 26 and the connected set of conveyor wheels 23 and gears 24 to rotate. The two sets of meshing gears 24 drive another set of gears 24 and conveyor wheels 23 to rotate, conveying the clamped copper wire 6 to the inside of the cylinder 31, continuously providing material for bending. The continuous bending and cutting process realizes batch standardized production. When the copper wire 6 passes through the cylinder 31 to the upper side of the frame 47, the motor 41 drives the synchronous pulley 43 to rotate, and the synchronous belt 44 drives another set of synchronous pulleys 43 to simultaneously drive gears 24 and 25. 42 rotates, and the rotating gear 42 drives the half gear 45 meshing on one side to rotate outside the cylinder 31. The rotating half gear 45 drives the fixed rod 46 and the bending shaft 48 to rotate in the movable opening 411. The rotation of the bending shaft 48 can bend the copper wire 6 extending from the cylinder 31. The motor 410 drives the gear 49 to rotate, driving the meshing bending shaft 48 to slide between the two sets of fixed rods 46, so that the bending shaft 48 retracts to the inside of the half gear 45. At this time, by driving the half gear 45, the bending shaft 48 can be moved to the upper or lower side of the copper wire 6, and then extended for bending, thereby realizing different bending operations and flexibly adapting to various bending requirements such as L-shaped and U-shaped inside the converter. Next, motor 52 drives gear 4 53 to rotate, driving meshing gear 54. Two sets of drive ports 55 drive two sets of shafts 56, cutters 57, and connecting rods 58 to move closer together. The connecting rods 58 slide in the guide port 35, pushing the hollow plate 34 and grinding sleeve 312 to move backward. After moving out of the cutting position, the two sets of cutters 57 quickly cut the copper wire 6, realizing continuous and rapid cutting, which brings significant production and quality advantages. In addition, after the two sets of cutters 57 have unfolded, the two sets of connecting rods 58 drive the hollow plate 34 forward through the guide port 35, so that the grinding sleeve 312 moves to the position where the copper wire 6 is cut. At the same time, the moved positioning rod 37 presses and fixes the cut section of copper wire 6, squeezing the spring. Spring 38 is driven by motor 2 316 to rotate synchronous pulley 317, which in turn drives synchronous belt 2 318 to rotate. Synchronous belt 2 318 then drives synchronous pulley 2 310 to rotate rapidly with the inner grinding sleeve 312. At this time, two sets of conveying wheels 23 drive the copper wire 6 to press against one end of the grinding sleeve 312, pushing the slide bar 313 on the grinding sleeve 312 to slide along the slide groove 311 and squeeze the spring 314. Meanwhile, the other side of the grinding sleeve 312 contacts the end face of the copper wire 6 that is held and fixed. The rapidly rotating grinding sleeve 312 grinds the end face of the copper wire 6, specifically solving the problem of cutting end face defects, eliminating burrs, collapsed edges and other protrusions, making the end face flat and smooth, and preventing personnel from being scratched by sharp burrs when handling it.
