Description

Technical Field

[0001] This application relates to the technical field of copper tube winding and blanking, and in particular to an automatic copper tube winding and blanking system. Background Art

[0002] Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes and are seamless tubes produced by pressing and drawing. Copper tubes have good thermal conductivity, electrical conductivity, and ductility, so they are widely used in cables, electrical components, heat dissipation tubes, water supply pipes, heating, and refrigeration pipes, etc. After the production of copper tubes, generally, the copper tubes are wound by a winding machine and coiled on a winding disk for storage and transportation. This transportation method is also used for the processing and transfer of copper tubes in the factory, and a single coil can transport a relatively large number of copper tubes.

[0003] Generally, after winding, an operator needs to push a blanking cart under the winding mechanism to carry away the copper tubes by the blanking cart. However, the copper coil is relatively heavy, and there are high risks during the packaging and handling of the copper tube coil, and a large amount of manual labor is required. The efficiency of manual transfer is relatively low, so it needs to be improved. Summary of the Invention

[0004] In order to improve the efficiency of copper tube coil blanking, this application provides an automatic copper tube winding and blanking system.

[0005] The automatic copper tube winding and blanking system provided by this application adopts the following technical solutions: The automatic copper tube winding and blanking system includes a double-station winding mechanism, a packaging mechanism, a blanking mechanism, a flipping mechanism, and a gantry manipulator. The double-station winding mechanism, the packaging mechanism, the blanking mechanism, and the flipping mechanism form a blanking production line, and one gantry manipulator can cooperate with multiple blanking production lines; the double-station winding mechanism includes a turntable and two winding components arranged on the turntable. The packaging mechanism is arranged on the winding component. The blanking mechanism and the flipping mechanism are arranged on one side of the turntable. The blanking mechanism includes a linear movement component and a blanking component. The linear movement component drives the blanking component to reciprocate between the turntable and the flipping mechanism to carry the steel tube coil.

[0006] By adopting the above technical solution, after the copper tube is produced, it is transported to the winding station. At this time, the turntable drives one of the winding assemblies to be located at the winding station for winding. After the winding is completed, the operator cuts the copper tube, and the turntable drives this winding assembly to move to the packaging station. At the same time, the other winding assembly is moved to the winding station for the next winding. The packaging mechanism packs the steel pipe coils moved to the packaging station. After the packaging is completed, the linear moving assembly drives the unloading assembly to move to the packaging station and transfers the steel pipe coils with the winding assembly. At this time, the packaged steel pipe coils are placed vertically in the unloading assembly. The linear moving assembly drives the unloading assembly to move to the side of the flipping mechanism. The unloading assembly is transferred to the flipping mechanism so that the steel pipe coils are placed flat on the flipping mechanism. The gantry manipulator transfers the steel pipe coils on the flipping assembly to the storage area for storage. The two unloading production lines are wound and unloaded at the same time, which improves production efficiency; only one operator is required to operate the whole process, and there is no need to carry heavy objects throughout the process, which saves manpower to a great extent.

[0007] Optionally, the winding assembly includes a base, a transverse moving member, a first support arm, a second support arm, a first winding disk and a second winding disk, the base is fixedly mounted on a turntable, and the fixed end of the transverse moving member is mounted on the base; the first support arm is fixedly connected to the movable end of the transverse moving member, the first winding disk is rotatably connected to an end of the first support arm away from the transverse moving member, the first support arm is provided with a winding motor, and the output end of the winding motor is connected to the first winding disk; the second support arm is slidably connected to the movable end of the transverse moving member, a transverse moving cylinder is provided between the second support arm and the transverse moving member, and the second winding disk is rotatably connected to an end of the second support arm away from the transverse moving member; a winding roller is provided between the first winding disk and the second winding disk, the copper tube is wound on the winding roller, the winding roller slides with the first winding disk, a telescopic member is installed on the first support arm, the telescopic member is connected to the winding roller to drive the winding roller to extend and retract between the first winding disk and the second winding disk, and the winding roller is movably connected to the second winding disk.

[0008] By adopting the above technical solution, after one winding is completed, the wound steel pipe coil is fixed on the winding roller, the first winding disc and the second winding disc are clamped from both sides, and after the operator and the packaging mechanism complete the packaging, the material is unloaded. When unloading, the telescopic member drives the winding roller to retract into the first winding disc, and at the same time, the horizontal moving cylinder drives the second support arm away from the first support arm, thereby driving the second winding disc away from the first winding disc, releasing the restriction on the steel pipe coil, and realizing the handover with the unloading assembly.

[0009] Optionally, the telescopic member includes a telescopic cylinder, a sleeve, a first bearing, and a second bearing. The outer shell of the telescopic cylinder is fixedly installed on the side of the first support arm away from the first winding disc. A receiving shell adapted to the winding roller is installed on the side wall of the first winding disc away from the second winding disc. A notch is formed in the thickness direction of the first winding disc and communicates with the inside of the receiving shell. The winding roller is slidably arranged in the first winding disc and the receiving shell. The receiving shell is rotatably connected to the first support arm. A hole for the cylinder shaft of the telescopic cylinder to pass through is formed in the receiving shell and the first support arm. The cylinder shaft of the telescopic cylinder is rotatably connected to the center of the end face of the winding roller through the first bearing. The sleeve is sleeved outside the cylinder shaft of the telescopic cylinder. The sleeve is rotatably connected to the first support arm through the second bearing. The sleeve is fixedly connected to the receiving shell. An annular groove is formed in the end face of the winding roller. The sleeve is inserted into the annular groove. A plurality of driving blocks are installed on the outer circumferential wall of the sleeve along the circumferential direction. Driving grooves adapted to the driving blocks are formed in the circumferential wall of the annular groove. The sleeve and the winding roller are slidably matched along the axial direction. The winding motor drives the sleeve to rotate through a pulley and a belt.

[0010] By adopting the above technical solution, during winding, the winding motor is started, and the sleeve is driven to rotate through a pulley and a belt. When the sleeve rotates, on the one hand, it directly drives the receiving shell and the first winding disc to rotate, and on the other hand, it drives the winding roller to rotate synchronously through the cooperation of the driving block and the driving groove, realizing the winding of the copper tube. During blanking, the telescopic cylinder is started to drive the cylinder shaft to retract. The retraction of the cylinder shaft drives the winding roller to retract, and the sliding fit between the winding roller and the first winding disc is realized through the cooperation of the driving block and the driving groove.

[0011] Optionally, a plurality of slope blocks are installed at one end of the winding roller close to the second winding disc. The plurality of slope blocks are arranged in an array along the circumferential direction of the winding roller. The projection of the slope block on the winding roller is arc-shaped, and the centers of the plurality of arcs coincide with the center of the end face of the winding roller. A slope groove adapted to the slope block is formed in the end face of the second winding disc. The vertical surface of the slope block abuts against the vertical surface of the second winding disc located in the slope groove to drive the second winding disc to rotate.

[0012] By adopting the above technical solution, the setting of the four slope blocks and the slope groove can align the winding roller with the second winding disc, so that the first winding disc and the second winding disc are also aligned, facilitating packing.

[0013] Optionally, a plurality of packing notches are respectively formed in the first winding disc and the second winding disc. The packing notches extend from the edge to the center. A plurality of packing through grooves are formed in the circumferential wall of the winding roller. The packing through grooves are arranged along the length direction of the winding roller. The two ends of one packing through groove are respectively communicated with one packing notch of the first winding disc and the second winding disc.

[0014] By adopting the above technical solution, the packing mechanism bypasses the packing belt around the copper tube coil through the packing notch and the packing through groove. The operator cuts the packing belt and fixes the packing belt with a pneumatic nail gun to complete the installation of one packing belt. Repeat the above steps to install four packing belts around the copper tube coil to reinforce the copper tube coil and prevent the copper tubes from spreading apart.

[0015] Optionally, the packing mechanism includes a feeding gripper, a receiving gripper, a packing driving assembly, and a packing feeding assembly. The two packing driving assemblies are respectively installed on the first support arm and the second support arm, and the two packing driving assemblies are respectively driven by a first winding disc and a second winding disc; the feeding gripper is arranged on the second winding disc, the receiving gripper is arranged on the first winding disc, the feeding gripper and the receiving gripper are respectively connected to a packing driving assembly, and the packing feeding assembly is installed on the feeding gripper; the sizes of the feeding gripper and the receiving gripper are adapted to the size of the packing through groove.

[0016] By adopting the above technical solution, after winding is completed, the operator controls the first winding disc, the second winding disc, and the winding roller to rotate to a pre-set packing station through the winding motor. At this time, the feeding gripper aligns with a packing notch on the second winding disc, the receiving gripper aligns with the corresponding packing notch on the first winding disc, and the feeding gripper and the receiving gripper are located on both sides of the corresponding packing through groove at this time. The two packing driving assemblies are started simultaneously to drive the feeding gripper and the receiving gripper to approach each other. The feeding gripper passes through the packing notch on the second winding disc and enters the packing through groove, and the receiving gripper passes through the packing notch on the first winding disc and enters the packing through groove, and finally stops moving when they meet. The feeding gripper releases the clamping of the packing belt, the receiving gripper clamps the end of the packing belt, and then the two packing driving assemblies are started simultaneously again to drive the feeding gripper and the receiving gripper to move away from each other. The feeding gripper leaves the packing through groove and moves to the outside of the second winding disc, and the receiving gripper clamps the packing belt and leaves the packing through groove and moves to the outside of the first winding disc to complete the process of threading the packing belt inside the copper tube coil. Subsequently, the two packing driving assemblies drive the feeding gripper and the receiving gripper to move along the length direction parallel to the packing notch. After moving to the outside of the copper tube coil, the two packing driving assemblies drive the feeding gripper and the receiving gripper to approach each other again, and another handover of the packing belt is carried out on the outside of the copper tube coil. At this time, the packing belt winds around the inside and outside of the copper tube coil once. The operator cuts the packing belt and fixes the packing belt with a pneumatic nail gun to complete the installation of one packing belt.

[0017] Optionally, the packing driving assembly includes a mounting plate, a sliding plate, a driving cylinder, a connecting rod and a driving rod. The mounting plate is fixedly installed on the first support arm or the second support arm. The sliding plate is slidably connected to the mounting plate. The driving cylinder is installed on the mounting plate. The driving cylinder is connected to the sliding plate through a rod. A U-shaped groove is formed in the mounting plate, and a V-shaped groove is formed in the sliding plate. A square slider and a columnar slider are sequentially installed on the driving rod along the length direction. The square slider is slidably arranged in the U-shaped groove, and the columnar slider is slidably arranged in the V-shaped groove. One end of the connecting rod is connected to the driving rod, and the other end is connected to the feeding gripper or the receiving gripper.

[0018] By adopting the above technical solution, the driving cylinder drives the sliding plate to reciprocate relative to the mounting plate. Under the limiting action of the square slider and the U-shaped groove, the driving rod reciprocates along the track of the U-shaped groove. The movement of the driving rod drives the feeding gripper or the receiving gripper to reciprocate along the track of the U-shaped groove inside and outside the copper tube coil through the connecting rod. Combining the cooperation of the feeding gripper and the receiving gripper, the automatic threading of the packing belt is realized.

[0019] Optionally, the packing feeding assembly includes a storage tray, a guiding pipe and a feeding pipe. The storage tray is arranged on the base and is used for storing the coiled packing belt. The guiding pipe is fixedly installed on the storage tray. The feeding pipe is fixedly installed on the feeding gripper. The outlet of the feeding pipe is arranged between the two claws of the feeding gripper. The packing belt sequentially passes through the guiding pipe and the feeding pipe to reach the feeding gripper.

[0020] Optionally, the blanking assembly includes a seat frame, a backing plate, a bracket, a clamping plate and a clamping cylinder. The seat frame is installed on the movable end of the linear moving assembly. The backing plate is fixedly installed on the seat frame. The bracket is fixedly installed on the seat frame and is located on one side of the backing plate. The clamping plate is rotatably installed on the top of the bracket. The middle of the clamping plate is rotatably connected to the top of the bracket through a rotating shaft. The housing of the clamping cylinder is rotatably installed on the bracket. The cylinder shaft of the clamping cylinder is rotatably connected to one end of the clamping plate through a rotating shaft. The clamping plate is located above the backing plate. A cotton pad is wound on the backing plate. A cotton pad is also wound on the end of the clamping plate away from the clamping cylinder. One end of the backing plate close to the bracket is bent upward.

[0021] By adopting the above technical solution, when blanking is required, the linear moving assembly drives the seat frame to approach the copper tube coil until the backing plate moves under the copper tube coil and just contacts the copper tube coil. After the first winding disc and the second winding disc are separated, the copper tube coil is placed on the backing plate. At this time, the cylinder shaft of the clamping cylinder extends out, driving the clamping plate to rotate clockwise and approach the copper tube coil from above until the cotton pad on the clamping plate abuts against the copper tube coil. The linear moving assembly drives the seat frame to move to the side of the flipping mechanism.

[0022] Optionally, the flipping mechanism includes a fixed seat, a transfer table, a flipping cylinder, a receiving beam, and a receiving cylinder. The fixed seat is installed on one side of the turntable. The transfer table is rotatably installed on the fixed seat. The housing of the flipping cylinder is rotatably connected to the fixed seat through a rotating shaft. The cylinder rod of the flipping cylinder is rotatably connected to the transfer table through a rotating shaft. A notch is formed on the transfer table. The receiving beam is rotatably installed in the notch. The housing of the receiving cylinder is rotatably connected to the transfer table through a rotating shaft. The cylinder rod of the receiving cylinder is rotatably connected to the receiving beam through a rotating shaft.

[0023] By adopting the above technical solution, when the seat frame drives the copper tube coil to move to one side of the fixed seat, the cylinder rod of the flipping cylinder extends out, driving the transfer table to rotate from horizontal to vertical. Subsequently, the cylinder rod of the receiving cylinder extends out, driving the receiving beam to rotate to form a 90-degree angle with the transfer table. At this time, the plane where the receiving beam is located is parallel to the horizontal plane, and the top surface of the receiving beam is in contact with the inner side wall of the copper tube coil. The cylinder rod of the clamping cylinder retracts, driving the clamping plate to rotate counterclockwise away from the copper tube coil. At the same time, the linear movement component drives the seat frame to leave, and the copper tube coil is hung on the receiving beam. Subsequently, the cylinder rod of the flipping cylinder retracts, driving the transfer table to rotate from vertical to horizontal. The receiving beam and the transfer table drive the copper tube coil to rotate until it is placed flat on the transfer table. Then, the cylinder rod of the receiving cylinder retracts, driving the receiving beam to rotate back into the notch on the transfer table, facilitating the transfer and stacking of the copper tube coil by the gantry manipulator.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the copper tube production is completed, it is conveyed to the winding station. At this time, the turntable drives one of the winding components to be located at the winding station for winding. After winding is completed, the operator cuts off the copper tube. The turntable drives this winding component to move to the packing station. At the same time, the other winding component is moved to the winding station for the next winding. The packing mechanism packs the steel tube coil that has moved to the packing station. After packing is completed, the linear movement component drives the blanking component to move to the packing station and conducts the handover of the steel tube coil with the winding component. At this time, the packed steel tube coil is placed vertically in the blanking component. The linear movement component drives the blanking component to move to the side of the flipping mechanism, and the blanking component conducts the handover with the flipping mechanism, so that the steel tube coil is placed flat on the flipping mechanism. The gantry manipulator transfers the steel tube coil on the flipping component to the storage area for storage. Two blanking production lines conduct winding and blanking simultaneously, improving production efficiency; only one operator is required for the whole process, and there is no need to carry heavy objects throughout the process, greatly saving labor; 2. After winding is completed, the operator controls the first winding disc, the second winding disc, and the winding roller to rotate to a pre-set packing station through the winding motor. At this time, the feeding gripper aligns with a packing notch on the second winding disc, the receiving gripper aligns with the corresponding packing notch on the first winding disc, and the feeding gripper and the receiving gripper are located on both sides of the corresponding packing through slot. The two packing driving components are started simultaneously, driving the feeding gripper and the receiving gripper to approach each other. The feeding gripper passes through the packing notch on the second winding disc and enters the packing through slot, and the receiving gripper passes through the packing notch on the first winding disc and enters the packing through slot, and stops moving when they finally meet. The feeding gripper releases the clamping of the packing belt, the receiving gripper clamps the end of the packing belt, and then the two packing driving components are started simultaneously again, driving the feeding gripper and the receiving gripper to move away from each other. The feeding gripper moves out of the packing through slot to the outside of the second winding disc, and the receiving gripper clamps the packing belt and moves out of the packing through slot to the outside of the first winding disc, completing the threading process of the packing belt inside the copper tube coil. Subsequently, the two packing driving components drive the feeding gripper and the receiving gripper to move along the length direction parallel to the packing notch. After moving to the outside of the copper tube coil, the two packing driving components drive the feeding gripper and the receiving gripper to approach each other again, and conduct another handover of the packing belt on the outside of the copper tube coil. At this time, the packing belt winds around the inside and outside of the copper tube coil once. The operator cuts off the packing belt and fixes the packing belt with a pneumatic nail gun, completing the installation of one packing belt; 3. The driving cylinder drives the sliding plate to reciprocate relative to the mounting plate. Under the limiting action of the square slider and the U-shaped groove, the driving rod reciprocates along the trajectory of the U-shaped groove. The movement of the driving rod drives the feeding gripper or the receiving gripper to reciprocate along the trajectory of the U-shaped groove inside and outside the copper tube coil through the connecting rod. Combined with the cooperation of the feeding gripper and the receiving gripper, the automatic threading of the packing belt is realized. Description of the Drawings

The arrangement of the four slope blocks 252 and the slope grooves 261 can align the winding roller 27 with the second winding disc 26, so as to align the first winding disc 25 with the second winding disc 26, which is convenient for packing.

[0046] Refer toFigure 6 and Figure 7 On the first winding disc 25 and the second winding disc 26, four packing notches 253 are respectively formed, and the packing notches 253 extend from the edge towards the center. Four corresponding packing through slots 273 are formed on the peripheral wall of the winding roller 27. The packing through slots 273 are arranged along the length direction of the winding roller 27, and notches are formed on the accommodating shell 251 corresponding to the packing through slots 273. Both ends of one packing through slot 273 are respectively communicated with one packing notch 253 of the first winding disc 25 and the second winding disc 26.

[0047] The packing mechanism 3 bypasses the packing belt 342 around the copper tube coil through the packing notch 253 and the packing through slot 273. The operator cuts the packing belt 342 and fixes the packing belt 342 with a pneumatic nail gun, completing the installation of one packing belt 342. Repeat the above steps to install four packing belts 342 around the copper tube coil to reinforce the copper tube coil and prevent the copper tubes from spreading.

[0048] Refer to Figure 7 、 Figure 8 and Figure 3 As shown in, the packing mechanism 3 includes a feeding jaw 31, a receiving jaw 32, a packing driving assembly 33 and a packing feeding assembly 34. Two packing driving assemblies 33 are respectively installed on the first support arm 23 and the second support arm 24. The feeding jaw 31 is arranged on the second winding disc 26, the receiving jaw 32 is arranged on the first winding disc 25. The feeding jaw 31 and the receiving jaw 32 are respectively connected with one packing driving assembly 33, and the packing feeding assembly 34 is installed on the feeding jaw 31; the sizes of the feeding jaw 31 and the receiving jaw 32 are adapted to the size of the packing through slot 273. The feeding jaw 31 is a micro jaw purchased in the market for the receiving jaw 32, and the prior art will not be elaborated.

[0049] Refer to Figure 8 and Figure 9 As shown in, the packing feeding assembly 34 includes a storage disc 341, a guiding tube 343 and a feeding tube. The storage disc 341 is arranged on the base 21, the packing belt 342 is wound and placed in the storage disc 341. The guiding tube 343 is fixedly installed on the storage disc 341, the feeding tube is fixedly installed on the feeding jaw 31, the outlet of the feeding tube is arranged between the two jaws of the feeding jaw 31. The packing belt 342 passes through the guiding tube 343 and the feeding tube in sequence and reaches the feeding jaw 31, and the two jaws of the feeding jaw 31 clamp the end of the packing belt 342.

[0050] After winding is completed, the operator controls the first winding disc 25, the second winding disc 26, and the winding roller 27 to rotate to the pre-set packing station through the winding motor 22. At this time, the feeding gripper 31 aligns with a packing notch 253 on the second winding disc 26, the receiving gripper 32 aligns with the corresponding packing notch 253 on the first winding disc 25, and the feeding gripper 31 and the receiving gripper 32 are located on both sides of the corresponding packing through slot 273 at this time. The two packing driving components 33 are started simultaneously, driving the feeding gripper 31 and the receiving gripper 32 to approach each other. The feeding gripper 31 passes through the packing notch 253 on the second winding disc 26 and enters the packing through slot 273, and the receiving gripper 32 passes through the packing notch 253 on the first winding disc 25 and enters the packing through slot 273, and stops moving when they finally meet. The feeding gripper 31 releases the clamping of the packing belt 342, the receiving gripper 32 clamps the end of the packing belt 342, and then the two packing driving components 33 are started simultaneously again, driving the feeding gripper 31 and the receiving gripper 32 to move away from each other. The feeding gripper 31 leaves the packing through slot 273 and moves to the outside of the second winding disc 26, and the receiving gripper 32 clamps the packing belt 342 and leaves the packing through slot 273 and moves to the outside of the first winding disc 25, completing the threading process of the packing belt 342 inside the copper tube coil.

[0051] Subsequently, the two packing driving components 33 drive the feeding gripper 31 and the receiving gripper 32 to move along the length direction parallel to the packing notch 253. After moving to the outside of the copper tube coil, the two packing driving components 33 drive the feeding gripper 31 and the receiving gripper 32 to approach each other again, and a handover of the packing belt 342 is carried out again on the outside of the copper tube coil. At this time, the packing belt 342 winds around the inside and outside of the copper tube coil for one circle. The operator cuts off the packing belt 342 and fixes the packing belt 342 with a pneumatic nail gun, completing the installation of one packing belt 342.

[0052] Refer to Figure 6 and Figure 7, the packing drive assembly 33 includes a mounting plate 331 which is fixedly installed on the first support arm 23 or the second support arm 24, and the mounting plate 331 is arranged horizontally. A sliding plate 332 is arranged on the mounting plate 331, and a track 3312 parallel to the radial direction of the first winding disc 25 is installed on the mounting plate 331. The sliding plate 332 is slidably connected to the mounting plate 331 through the track 3312. A driving cylinder 333 is installed on the mounting plate 331, and the cylinder shaft of the driving cylinder 333 is connected to the sliding plate 332 through a rod to drive the sliding plate 332 to move radially along the first winding disc 25 in the horizontal direction. A U-shaped groove 3311 is formed in the mounting plate 331, and a V-shaped groove 3321 is formed in the sliding plate 332. A driving rod 335 is arranged in the U-shaped groove 3311 and the V-shaped groove 3321. A square slider 336 and a columnar slider 337 are sequentially installed on the driving rod 335 along the length direction. The square slider 336 is slidably arranged in the U-shaped groove 3311, and the columnar slider 337 is slidably arranged in the V-shaped groove 3321. A connecting rod 334 is fixedly connected to the driving rod 335, and one end of the connecting rod 334 far from the driving rod 335 is connected to the feeding gripper 31 or the receiving gripper 32.

[0053] The driving cylinder 333 drives the sliding plate 332 to reciprocate relative to the mounting plate 331. Under the restricting action of the square slider 336 and the U-shaped groove 3311, the driving rod 335 reciprocates along the track of the U-shaped groove 3311. The movement of the driving rod 335 drives the feeding gripper 31 or the receiving gripper 32 to reciprocate along the track of the U-shaped groove 3311 inside and outside the copper tube coil through the connecting rod 334. Combining with the cooperation of the feeding gripper 31 and the receiving gripper 32, the automatic threading of the packing belt 342 is realized.

[0054] Refer to Figure 10 and Figure 11 , the blanking assembly 5 includes a seat frame 51, a backing plate 52, a bracket 53, a clamping plate 54 and a clamping cylinder 55. The seat frame 51 is installed on the movable end of the linear movement assembly 4. The backing plate 52 is fixedly installed on the seat frame 51. The bracket 53 is fixedly installed on the seat frame 51 and is located on one side of the backing plate 52. The clamping plate 54 is rotatably installed on the top of the bracket 53. The middle part of the clamping plate 54 is rotatably connected to the top of the bracket 53 through a rotating shaft. The housing of the clamping cylinder 55 is rotatably installed on the bracket 53. The cylinder shaft of the clamping cylinder 55 is rotatably connected to one end of the clamping plate 54 through a rotating shaft. The clamping plate 54 is located above the backing plate 52. A cotton pad is wound on the backing plate 52, and a cotton pad is also wound on the end of the clamping plate 54 far from the clamping cylinder 55; one end of the backing plate 52 close to the bracket 53 is bent upward.

[0055] When blanking is required, the linear movement assembly 4 drives the seat frame 51 to approach the copper tube coil until the backing plate 52 moves below the copper tube coil and the backing plate 52 just contacts the copper tube coil. After the first winding disc 25 and the second winding disc 26 are separated, the copper tube coil is placed on the backing plate 52. At this time, the cylinder shaft of the clamping cylinder 55 extends, driving the clamping plate 54 to rotate clockwise and approach the copper tube coil from above until the cotton pad on the clamping plate 54 abuts against the copper tube coil. The linear movement assembly 4 drives the seat frame 51 to move to the side of the flipping mechanism 6.

[0056] Refer to Figure 10 and Figure 11 , the flipping mechanism 6 includes a fixed seat 61, a transfer table 62, a flipping cylinder 63, a receiving beam 64 and a receiving cylinder 65. The fixed seat 61 is installed on one side of the turntable 1. The transfer table 62 is rotatably installed on the fixed seat 61. The housing of the flipping cylinder 63 is rotatably connected to the fixed seat 61 through a rotating shaft. The cylinder shaft of the flipping cylinder 63 is rotatably connected to the transfer table 62 through a rotating shaft. A notch is provided on the transfer table 62. The receiving beam 64 is rotatably installed in the notch. The housing of the receiving cylinder 65 is rotatably connected to the transfer table 62 through a rotating shaft. The cylinder shaft of the receiving cylinder 65 is rotatably connected to the receiving beam 64 through a rotating shaft.

[0057] When the seat frame 51 drives the copper tube coil to move to one side of the fixed seat 61, the cylinder shaft of the flipping cylinder 63 extends, driving the transfer table 62 to rotate from horizontal to vertical. Subsequently, the cylinder shaft of the receiving cylinder 65 extends, driving the receiving beam 64 to rotate to an angle of 90 degrees with the transfer table 62. At this time, the plane where the receiving beam 64 is located is parallel to the horizontal plane, and the top surface of the receiving beam 64 abuts against the inner side wall of the copper tube coil. The cylinder shaft of the clamping cylinder 55 retracts, driving the clamping plate 54 to rotate counterclockwise and away from the copper tube coil. At the same time, the linear movement assembly 4 drives the seat frame 51 to leave. The copper tube coil is hung on the receiving beam 64. Subsequently, the cylinder shaft of the flipping cylinder 63 retracts, driving the transfer table 62 to rotate from vertical to horizontal. The receiving beam 64 and the transfer table 62 drive the copper tube coil to rotate until it is flat on the transfer table 62. Then, the cylinder shaft of the receiving cylinder 65 retracts, driving the receiving beam 64 to rotate back into the notch on the transfer table 62, facilitating the transfer and stacking of the copper tube coil by the gantry manipulator.

[0058] The implementation principle of the automatic unloading system for copper tube winding in the embodiment of the present application is as follows: after the copper tube is produced, it is wound on the winding roller 27 located at the winding station. After the winding is completed, the copper tube is cut off by the operator, and the turntable 1 drives it to move to the packaging station. The winding motor 22 drives the first winding disk 25, the second winding disk 26 and the winding roller 27 to rotate, so that one set of packaging notches 253 and packaging slots 273 reach the plane where the feeding clamp 31 and the receiving clamp 32 are located. The feeding clamp 31 and the receiving clamp 32 are connected in the packaging slot 273 to allow the strapping tape 342 to pass through the inside of the copper tube roll. Then, the feeding clamp 31 and the receiving clamp 32 are connected for the second time on the outside of the copper tube roll to realize the automatic threading of the strapping tape 342. After the packaging is completed, the linear moving component 4 drives the frame 51 to move to the packaging station, and the steel tube roll is pressed against the pad 52 by the clamp 54 to complete the unloading. The linear moving assembly 4 drives the frame 51 to move to the side of the fixed seat 61, and the steel pipe coil is transferred to the receiving beam 64. Then the receiving beam 64 and the transfer platform 62 drive the copper pipe coil to rotate and lie flat on the transfer platform 62. The gantry manipulator transfers the steel pipe coil on the flip assembly to the storage area for storage. The two unloading production lines are unloading at the same time, which improves production efficiency; only one operator is required to operate the whole process, and there is no need to carry heavy objects, which saves manpower to a great extent.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
