DETAILED DESCRIPTION

[0030] The present invention is described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 6As shown, an intelligent hot tape welding machine of the present invention comprises a machine 1, wherein the machine 1 is provided with a feeding mechanism 2, a strap length fixing mechanism 3, a shearing mechanism 5, a folding mechanism 6 and a welding mechanism 7, the strap length fixing mechanism 3 is provided with a strap drawing manipulator 34 which is slidably arranged, the folding mechanism 6 is provided with a rotatable folding manipulator 64, the sliding strap drawing manipulator 34 is used for clamping the strapping tape fed by the feeding mechanism 2 and pulling the strapping tape along the length direction of the machine 1 to achieve a fixed length, the shearing mechanism 5 cuts the strapping tape after the length is fixed by the strap drawing manipulator 34, the folding manipulator 64 clamps and makes the free end of the cut strapping tape flip over a certain angle to overlap with its body, and the welding mechanism 7 welds the overlapping part of the strapping tape to form a buckle.

[0032] The feeding mechanism 2 is arranged at one end of the machine 1, so that the strapping tape can be wound around the feeding mechanism 2, and the strapping tape can be transported from the feeding end of the feeding mechanism 2 to the machine 1. The strapping length-fixing mechanism 3 is arranged along the length direction of the machine 1, so that the strapping manipulator 34 arranged slidably clamps the strapping tape and moves along the length direction of the machine 1 with the conveying end of the strapping length-fixing mechanism 3, thereby pulling the strapping tape.

[0033] The welding mechanism 7, the folding mechanism 6 and the shearing mechanism 5 are sequentially arranged at the feeding end of the feeding mechanism 2 along the length direction of the machine 1, so that the strapping tape transported outward from the feeding end of the feeding mechanism 2 is cut off sequentially by the shearing mechanism 5, and folded by the folding robot 64 of the folding mechanism 6, so that the free end of the strapping tape overlaps with the strapping tape body to form a buckle, and the buckle is welded into shape by the welding mechanism 7. The mechanized operation can work continuously for a long time, which helps to improve the efficiency of the end welding of the strapping tape.

[0034] During operation, the strapping tape is wound around the feeding mechanism 2, and the strapping tape is transported to the machine 1 through the feeding end of the feeding mechanism 2. The strapping length fixing mechanism 3 also works at the same time, so that the strapping tape manipulator 34 clamps the strapping tape and pulls the strapping tape along the length direction of the machine 1 along with the sliding strapping tape manipulator 34, so that the strapping tape passes through the welding mechanism 7, the folding mechanism 6 and the shearing mechanism 5 in sequence. After the strapping tape reaches the predetermined length, the feeding end of the feeding mechanism 2 stops conveying the strapping tape, and the strapping tape manipulator 34 also stops moving. The strapping tape is clamped by the strapping tape manipulator 34, so that the strapping tape is horizontally arranged on the machine. 1. The folding manipulator 64 of the folding mechanism 6 clamps the strapping tape, and the free end of the shearing mechanism 5 cuts off the strapping tape. The folding manipulator 64 of the folding mechanism 6 folds the cut end of the clamped strapping tape 180° toward the welding mechanism 7, so that the cut end of the strapping tape overlaps with the strapping tape body to form a buckle. The working end of the welding mechanism 7 welds the cut end of the strapping tape to the overlapping part of the strapping tape body, so that the buckle is formed and fixed. The welding operation of the cut end of the strapping tape is completed mechanized, and it can work continuously for a long time, which helps to improve the end welding efficiency of the strapping tape.

[0035] The feeding mechanism 2 of this embodiment includes a tape feeding frame 21, a tape reel 22 rotatably arranged on the tape feeding frame 21, a guide wheel assembly arranged on the tape feeding frame 21 or the machine 1, and a conveying device 25 for conveying the strapping tape, wherein the guide wheel assembly includes a first guide wheel 23 fixedly arranged at the lower part of the machine 1 and a second guide wheel 24 fixedly arranged at the upper part of the machine 1. Specifically, the tape reel 22 is carried by the tape feeding frame 21, and the tape reel 22 rotates on the tape feeding frame 21 through a rotating shaft. The first guide wheel 23 is fixed to one end of the lower part of the machine 1 facing the tape feeding frame 21 through a rotating seat, and the second guide wheel 24 is fixed to one end of the upper part of the machine 1 facing the tape feeding frame 21 through a rotating seat. The first guide wheel 23 and the second guide wheel 24 are both pulleys. The strapping tape is wound around the surface of the tape reel 22 and introduced into the conveying device 25 through the first guide wheel 23 and the second guide wheel 24.

[0036] In actual use, a guide groove is provided between the first guide wheel 23 and the second guide wheel 24, and the strapping belt is conveyed between the first guide wheel 23 and the second guide wheel 24 along the guide groove, so that the strapping belt is conveyed more smoothly and has stronger guidance, which is convenient for strapping belt conveying.

[0037] The strap length fixing mechanism 3 is also provided with a strap driving source for driving the strap manipulator 34 to slide. The machine 1 is provided with a first driver 4 . The conveying device 25 and the strap driving source are both in transmission connection with the first driver 4 .

[0038] The first driver 4 is a reduction motor, the fixed end of the first driver 4 is fixedly connected to the machine 1, and the output end of the first driver 4 is coaxially connected to the feed end of the feeding mechanism 2 and the belt drive source of the belt lengthening mechanism 3, so that the first driver 4 drives the feed end of the feeding mechanism 2 and the conveying end of the belt lengthening mechanism 3 to rotate simultaneously. In actual use, the fixed end of the first driver 4 is fixedly connected to the inside of the machine 1, and the first driver 4 drives the rotating shaft to rotate through the synchronous belt pulley group, and the rotating shaft is coaxially connected with the feed end of the feeding mechanism 2 and the conveying end of the belt lengthening mechanism 3, so that the feeding mechanism 2 and the belt lengthening mechanism 3 are driven together by the first driver 4, so that the feeding mechanism 2, the belt lengthening mechanism 3 and the first driver 4 work in coordination, and the correlation is strong, thereby improving the utilization rate of the first driver 4.

[0039] The conveying device 25 includes a conveying seat 251 fixedly arranged on the machine 1 by bolts and screw holes, and the conveying seat 251 is in the shape of a plate. The second guide wheel 24 is arranged at one end of the conveying seat 251 facing the tape reel 22, so as to be fixedly arranged on the upper part of the machine 1, and it is also convenient for the strapping tape wound around the second guide wheel 24 to be introduced into the conveying device 25. The conveying seat 251 is rotatably connected with a first rotating wheel 252 and a second rotating wheel 253, and the first rotating wheel 252 is arranged at one end of the conveying seat 251 facing the second guide wheel 24, so as to facilitate the strapping tape wound around the second guide wheel 24 to be introduced into the conveying device 25 through the first rotating wheel 252. A belt pressing wheel 254 is rotatably arranged between the first rotating wheel 252 and the second rotating wheel 253, and the strapping tape is wound around the first rotating wheel 252, the second rotating wheel 253 and the belt pressing wheel 254 and pressed tightly, so that the strapping tape is conveyed between the first rotating wheel 252, the second rotating wheel 253 and the belt pressing wheel 254 by friction, so that the conveying device 25 conveys the strapping tape.

[0040] The belt pressure wheel 254 is coaxially connected to the output end of the first driver 4 through a one-way bearing, so that when the output end of the first driver 4 rotates clockwise, the belt pressure wheel 254 is driven to rotate, thereby realizing the coaxial connection between the output end of the first driver 4 and the feeding end of the loading mechanism 2. When the output end of the first driver 4 rotates counterclockwise, the belt pressure wheel 254 does not rotate accordingly.

[0041] The conveying seat 251 is provided with an abutting brake member 26 for controlling the rotation or stopping of the belt pressing wheel 254. The output end of the abutting brake member 26 faces the belt pressing wheel 254. The abutting brake member 26 is a linear pneumatic cylinder or a linear electric cylinder. In actual use, a friction block is provided at the output end of the abutting brake member 26. When the output end of the abutting brake member 26 is extended, the friction block abuts against the belt pressing wheel 254 to limit the rotation of the belt pressing wheel 254, so that the belt pressing wheel 254 does not rotate with the output end of the first driver 4 or when the first driver 4 stops working, the rotation of the belt pressing wheel 254 is limited by the abutting brake member 26, so that the belt pressing wheel 254 maintains a state to reduce the reverse conveying of the strapping tape. When the output end of the first driver 4 rotates clockwise, the output end of the abutting brake member 26 is retracted, and the belt pressing wheel 254 rotates with the output end of the first driver 4 to work, thereby realizing the conveying of the strapping tape.

[0042] In actual use, a photoelectric sensor can be set between the conveying seat 251 and the first rotating wheel 252 and the second guide wheel 24 to detect the packing tape. When the predetermined length is reached, the photoelectric sensor cooperates with the abutting brake 26 through the PLC controller to stop the conveying device 25 from conveying the packing tape, so that the packing tape is conveyed according to the predetermined setting.

[0043] The tape reel 22 of this embodiment includes a braking device 27, which includes a braking pulley 271 coaxially fixedly connected to the tape reel 22 and a swing plate 272 rotatably connected to the tape feed frame 21. The swing plate 272 is rotatably connected to the tape feed frame 21 via a rotating shaft, so that the swing plate 272 swings along the rotating shaft with the tape feed frame 21.

[0044] A friction brake 273 is provided between the swing plate 272 and the brake pulley 271. The friction brake 273 is a belt, and the cross section of the belt can be triangular or trapezoidal. One end of the friction brake 273 is fixedly connected to one end of the swing plate 272, and the other end of the friction brake 273 is sleeved on the brake pulley 271. A swing rod 274 is fixedly provided at one end of the swing plate 272 away from the friction brake 273. The swing rod 274 is L-shaped. A third guide wheel 275 is provided at one end of the swing rod 274 away from the swing plate 272. The third guide wheel 275 is provided between the belt reel 22 and the first guide wheel 23. The third guide wheel 275 is provided between the belt reel 22 and the first guide wheel 23.

[0045] When in use, the strapping tape is led out from the tape winding reel 22, and then wound around the first guide wheel 23 via the third guide wheel 275. When the conveying device 25 conveys the strapping tape too fast, the strapping tape pulls the swing rod 274 downward through the third guide wheel 275, and at the same time, the swing plate 272 and the friction brake member 273 approach the first guide wheel 23, so that the friction brake member 273 is tightly wrapped around the brake pulley 271, which increases the friction force of the brake pulley 271 and slows down the rotation speed, thereby slowing down the rotation speed of the tape winding reel 22 and making the conveying device 25 convey the strapping tape at a uniform speed.

[0046] In actual use, two swing plates 272 are provided, and one end of the two swing plates 272 that are rotatably connected to the tape feed frame 21 is connected through a rotating shaft. The tape feed frame 21 is provided with a swing hole corresponding to the rotating shaft. The swing hole is arc-shaped. The rotating shaft rotates and slides in the swing hole, so that the two swing plates 272 swing along the rotating shaft and the swing hole and the tape feed frame 21. A limiting swing rod is provided at one end between the two swing plates 272 away from the tape feeding frame 21, and the limiting swing rod is provided above the tape feeding frame 21. When the limiting swing rod abuts against the tape feeding frame 21, the swing amplitude of the swing plate 272 can be limited to be too large, thereby ensuring the stable operation of the swing plate 272, such as preventing the swing plate 272 from swinging excessively toward the first guide wheel 23, thereby causing the friction brake component 273 to be too tightly wrapped around the brake pulley 271 and causing the brake pulley 271 to stop rotating, or preventing the swing plate 272 from swinging excessively away from the first guide wheel 23, thereby causing the friction brake component 273 and the brake pulley 271 to be separated too far and affect the normal operation of the friction brake component 273 and the brake pulley 271.

[0047] The welding mechanism 7 of this embodiment can be an ultrasonic welding machine or a laser welding machine. In this embodiment, the welding mechanism 7 is exemplified by an ultrasonic welding machine. The welding mechanism 7 includes a welding machine 71 vertically fixedly arranged in the machine 1 and a pressing device 72 fixedly arranged on the machine 1 for pressing the strapping belt against the welding end of the welding machine 71. The pressing device 72 is arranged above the welding machine 71. The pressing device 72 includes a pressing frame 721 fixedly arranged on the machine 1 by bolts and screw holes, a second driver 722 vertically fixedly arranged on the top of the pressing frame 721, and a pressing head 723 fixedly arranged at the output end of the second driver 722. The welding end of the welding machine 71 extends out of the machine 1, and the pressing head 723 faces the welding end of the welding machine 71, so that the pressing head 723 extends out with the output end of the second driver 722 and abuts against the welding end of the welding machine 71, and the pressing head 723 is separated from the welding end of the welding machine 71 as the output end of the second driver 722 shrinks.

[0048] During operation, the strapping tape is clamped by the free end of the strapping length-fixing mechanism 3, so that the strapping tape is horizontally arranged on the machine table 1, the welding end of the welding machine 71 is below the strapping tape, the second driver 722 and the pressing head 723 are above the strapping tape, the free end of the folding mechanism 6 clamps the cut end of the strapping tape and folds it 180° toward the welding mechanism 7, the overlapping part of the cut end of the strapping tape and the strapping tape body is located between the welding end of the welding machine 71 and the pressing head 723, the output end of the second driver 722 extends out, so that the pressing head 723 is close to the welding end of the welding machine 71, the overlapping strapping tape is pressed between the pressing head 723 and the welding end of the welding machine 71, the welding machine 71 is started, the buckle formed by the overlap of the cut end of the strapping tape and the strapping tape body is welded and formed, and the welding operation of the strapping tape end is completed.

[0049] The welding machine 71 of the present embodiment is provided with a belt pressing device 8 on the side facing the feeding end of the feeding mechanism 2. The belt pressing device 8 includes a pressing table 81 fixedly arranged on the machine table 1 for carrying the strapping tape, a belt pressing head 82 for pressing the strapping tape, and a third driver 83 for driving the belt pressing head 82. The third driver 83 is vertically fixed to the pressing frame 721 and the output end of the third driver 83 faces the pressing table 81. The belt pressing head 82 is fixed to the output end of the third driver 83. The third driver 83 is a linear pneumatic cylinder or a linear electric cylinder, which extends out through the output end of the third driver 83, so that the belt pressing head 82 is close to the pressing table 81 to press the strapping tape against the pressing table 81, thereby limiting the displacement of the strapping tape and straightening the strapping tape between the belt pressing device 8 and the folding mechanism 6, so as to facilitate the welding mechanism 7 to perform welding operations on the strapping tape. The output end of the third driver 83 retracts, so that the pressing head 82 moves away from the pressing platform 81, and the strapping tape is released and carried on the pressing platform 81. A strapping groove 811 is provided on the top of the pressing platform 81, and the strapping tape is restricted in the strapping groove 811 through the strapping groove 811, so that the strapping tape is not easy to fall off the pressing platform 81, which makes it easy for the free end of the strap fixing mechanism 3 to clamp and pull the strapping tape.

[0050] The belt pressing device 8, the welding mechanism 7 and the folding mechanism 6 are each provided with two groups, and each folding mechanism 6, each welding mechanism 7 and each belt pressing device 8 are symmetrically arranged on the machine 1 along the shearing mechanism 5 as the central axis. The belt pressing device 8, the welding mechanism 7 and the folding mechanism 6 are each provided with two groups, and the two cut ends of the strapping tape cut off by the shearing mechanism 5 can be welded at the same time, thereby improving the efficiency of the welding operation of the end of the strapping tape.

[0051] The strap length fixing mechanism 3 of this embodiment is also provided with a strap driving source for driving the strap manipulator 34 to slide, and the strap driving source includes a driving wheel 31 and a driven wheel 32 which are rotatably arranged on the machine 1 through a swivel seat, and the driving wheel 31 is coaxially connected with the output end of the first driver 4, and a strap transmission member 33 is arranged between the driving wheel 31 and the driven wheel 32, so that the output end of the first driver 4 is connected to the strap driving source in a transmission manner, so that the conveying device 25 and the strap driving source are both connected to the first driver 4 in a transmission manner. The driving wheel 31 and the driven wheel 32 can be synchronous wheels, and the strap transmission member 33 is a synchronous belt, or the driving wheel 31 and the driven wheel 32 are sprocket wheels, and the strap transmission member 33 is a combination of chains.

[0052] The belt-pulling robot 34 is disposed on the belt-pulling transmission member 33 , so that the belt-pulling robot 34 is displaced as the belt-pulling transmission member 33 rotates.

[0053] The strapping manipulator 34 includes a strapping bracket 341 fixedly connected to the strapping transmission member 33, a transverse driver 342 fixed to the strapping bracket 341, and a strapping manipulator body 343 fixed to the output end of the transverse driver 342, so that the strapping manipulator 34 is connected to the strapping transmission member 33 through the strapping bracket 341. The transverse driver 342 is a pneumatic sliding table cylinder or an electric sliding table cylinder, so that the output end of the transverse driver 342 slides more stably, so that the strapping manipulator body 343 is convenient for clamping the strapping belt as the output end of the transverse driver 342 extends out, and the strapping manipulator body 343 retreats as the output end of the transverse driver 342 contracts and moves as the strapping transmission member 33 rotates. The strapping manipulator body 343 is a pneumatic finger cylinder or an electric finger cylinder, so that the strapping manipulator body 343 can clamp the strapping belt.

[0055] The first drive 4 then drives the driving wheel 31 to rotate clockwise, and the driving wheel 31 drives the driving belt transmission member 33 to rotate. The driving belt manipulator 34 moves along the length direction of the machine 1 with the driving belt transmission member 33. When the driving wheel 31 rotates, the driving belt drives the driving belt transmission member 33 to rotate. The driving belt manipulator 34 moves along the length direction of the machine 1 with the driving belt transmission member 33. When the driving wheel 31 rotates, the driving belt drives the driving belt transmission member 33 to rotate. When the driving belt reaches the predetermined position, the first drive 4 stops working, so that the strapping belt of the preset length is clamped by the driving belt manipulator body 343 and is horizontally arranged on the machine 1. When the free end of the folding mechanism 6 clamps the strapping belt, the driving belt manipulator body 343 releases the strapping belt, and the first drive 4 drives the driving wheel 31 to rotate counterclockwise, so that the driving belt transmission member 33 drives the driving belt manipulator body 343 to reset to the position aligned with the feeding end of the feeding mechanism 2 and clamp the strapping belt again, so as to realize that the strap fixing mechanism 3 clamps the strapping belt and moves along the length direction of the machine 1 with the conveying end of the strap fixing mechanism 3 to pull the strapping belt.

The fixed end of the fourth driver 63 is fixedly connected to the machine base 61, and the output end of the fourth driver 63 is connected to the folding table 62, so that the fourth driver 63 is fixedly set on the machine base 61 and drives the folding table 62 to slide, so that the folding table 62 slides as the fourth driver 63 extends or contracts, which is convenient for the folding robot 64 to adjust the distance from the strapping belt, and convenient for the folding robot 64 to approach the strapping belt to clamp the strapping belt or the folding robot 64 to release the strapping belt and stay away from the strapping belt.

[0058] The output end of the fifth driver 65 is provided with a first transmission member 651, the folding platform 62 is fixedly provided with a flip seat 621, the fixed end of the folding manipulator 64 is provided with a flip shaft 641, the flip seat 621 is rotatably connected with the flip shaft 641, so that the folding manipulator 64 is rotatably connected with the folding platform 62. The flip shaft 641 is provided with a second transmission member 642, and the first transmission member 651 is in transmission connection with the second transmission member 642, so that the fifth driver 65 drives the folding manipulator 64 to rotate through the first transmission member 651 and the second transmission member 642, so that the free end of the folding mechanism 6 folds the clamped strapping tape.

[0059] In actual use, the first transmission member 651 is a rack, the second transmission member 642 is a gear, the fifth driver 65 is a linear pneumatic cylinder or a linear electric cylinder, or the first transmission member 651 is a pot rod, the second transmission member 642 is a pot wheel, and the fifth driver 65 is a reduction motor. The combination can realize that the fifth driver 65 drives the folding robot 64 to rotate through the first transmission member 651 and the second transmission member 642.

[0060] The machine base 61 of this embodiment includes a slide 66 fixed on the machine platform 1. The machine base 61 is slidably connected to the slide 66.

[0063] During operation, the folding table 62 slides as the fourth driver 63 extends out and conveys, the folding robot 64 approaches the strapping tape, and the free end of the folding robot 64 clamps the strapping tape. The fifth driver 65 drives the folding robot 64 to flip 180° in the direction of the welding mechanism 7, so that the end of the strapping tape cut off by the shearing mechanism 5 flips 180° in the direction of the welding mechanism 7 and overlaps with the strapping tape body to form a buckle. The free end of the clamping robot 69 is combined to clamp the two sides of the overlapping part of the cut end of the strapping tape and the strapping tape body, so that the cut end of the strapping tape and the strapping tape body remain in an overlapping state, and the free end of the folding robot 64 releases When releasing the strapping tape, the machine base 61 is displaced laterally as the output end of the sixth driver 68 extends out, so that the free end of the folding robot 64 pushes the cut end of the strapping tape to move along the strapping tape body in a direction away from the clamping robot 69, thereby increasing the internal diameter of the buckle. The machine base 61 is then displaced laterally and reset as the output end of the sixth driver 68 contracts, so that the free end of the folding robot 64 is away from the inner wall of the buckle, facilitating the separation of the free end of the folding robot 64 from the inner wall of the buckle. The folding table 62 slides as the fourth driver 63 contracts during conveying, and the folding robot 64 is away from the strapping tape, so that the folding robot 64 releases the strapping tape and moves away from the strapping tape.

[0065] During operation, the output end of the seventh driver 52 extends, and the shear 53 extends accordingly and approaches the strapping tape. The free ends of the shear 53 merge to cut the strapping tape. After cutting the strapping tape, the output end of the seventh driver 52 contracts, and the shear 53 retracts accordingly and moves away from the strapping tape, thereby reducing the impact on the strapping tape transportation.

[0066] The machine 1 of the present embodiment also includes an automatic flipping and unloading mechanism 9, which includes a slide rail seat 91 fixedly arranged on the machine 1, a sliding platform 92 slidably arranged on the slide rail seat 91, an eighth driver 93 driving the sliding platform 92 to slide on the slide rail seat 91, a flipping and unloading manipulator 94 rotatably connected to the sliding platform 92, and a ninth driver 95 driving the flipping and unloading manipulator 94 to rotate.

In actual use, a gear rack can be arranged between the sliding platform 92 and the output end of the eighth driver 93, and the eighth driver 93 drives the sliding platform 92 to slide on the slide rail seat 91 through the gear rack, so that the sliding platform 92 slides on the slide rail seat 91 more smoothly.

[0067] The flipping and unloading manipulator 94 includes a rotating seat 96 fixed to the sliding table 92, and a shaft 97 is rotatably connected in the rotating seat 96, so that the flipping and unloading manipulator 94 can be rotatably connected with the sliding table 92.

[0070] During operation, the strapping belt is clamped by the free end of the strap-drawing and length-fixing mechanism 3, so that the strapping belt is horizontally arranged on the machine 1. The output end of the eighth driver 93 extends to drive the sliding table 92 to slide along the slide rail seat 91 toward the direction close to the feeding mechanism 2. The output end of the ninth driver 95 contracts to drive the flipping and unloading manipulator 94 to flip 180° toward the strap-drawing and length-fixing mechanism 3. The output end of the telescopic driver 98 extends to make the flipping and unloading manipulator body 99 close to the strapping belt. The free ends of the flipping and unloading manipulator body 99 are combined to clamp the strapping belt, so that the automatic flipping and unloading mechanism 9 clamps the strapping belt. When the free end of the strap-drawing and length-fixing mechanism 3 is separated from the strapping belt, the automatic flipping and unloading mechanism 9 continues to clamp the strapping belt. After the welding operation on the cut end of the strapping tape is completed, the output end of the eighth driver 93 contracts and drives the sliding table 92 to slide along the slide rail seat 91 in the direction away from the shearing mechanism 5, so that the automatic flipping and unloading mechanism 9 clamps the strapping tape and pulls it in the direction away from the loading mechanism 2, so that the strapping tape that has completed the welding operation is separated from the welding mechanism 7, the folding mechanism 6 and the shearing mechanism 5. The output end of the ninth driver 95 extends out to drive the flipping and unloading manipulator 94 to flip 180° away from the strap fixing length mechanism 3, so that the strapping tape that has completed the welding operation is transferred to another position, and the free end of the flipping and unloading manipulator body 99 opens to separate the strapping tape that has completed the welding operation from the automatic flipping and unloading mechanism 9, thereby completing the unloading operation.
