Description

Technical Field

[0001] This invention relates to the technical field of threading heat shrink tubing onto wires, and in particular to a multi-specification double-threading heat shrink tubing device. Background Technology

[0002] Threading wires through heat shrink tubing involves inserting and installing the wires into the heat shrink tubing. Traditionally, this process involves manually marking the wires and then manually threading them through the tubing using a heat gun. This method is not only inefficient but also extremely labor-intensive.

[0003] To improve the efficiency of heat shrink tubing insertion while reducing the manual labor required, existing technologies, such as Chinese Patent Application No. 201511013481.0, disclose a fully automatic heat shrink tubing insertion machine. This machine includes a frame and a worktable. The worktable is equipped with a wire feeding mechanism, a wire cutting and stripping mechanism, a stripping robot, a first tubing insertion mechanism, a terminal crimping mechanism, a correction mechanism, a heat shrinking mechanism, a coding machine, a second tubing insertion mechanism, a first transfer robot, a second transfer robot, a third transfer robot, a fourth transfer robot, a fifth transfer robot, a sixth transfer robot, and a unloading robot. This achieves automated processing of the wire harness, including two heat shrink tubing insertions, one terminal crimping, one heat shrinking, and one coding.

[0004] However, although the aforementioned fully automatic heat shrink tubing threading machine can improve the efficiency of heat shrink tubing threading and reduce the manual labor intensity required for threading, it is only applicable to threading heat shrink tubing of a single specification, resulting in poor applicability of the fully automatic heat shrink tubing threading machine.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 3 As shown, in one embodiment, a multi-specification double-threading heat shrink tubing device 10 is used to thread heat shrink tubing through both ends of a bent wire 20, achieving the effect of double-threading heat shrink tubing through both ends of the bent wire 20. Further, the multi-specification double-threading heat shrink tubing device 10 includes a wire clamping and threading device 100, a heat shrink tubing cutting device 200, a heat shrinking device 300, a heat shrink tubing switching device 400, a heat shrink tubing feeding device 500, and a tubing guiding device 600. Figure 4 As shown, the heat shrink tubing switching device 400 is used to carry multiple heat shrink tubing materials 30 and switch one of the heat shrink tubing materials 30 to the working position so as to carry out subsequent conveying operations on the heat shrink tubing material 30.

[0039] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, the heat shrink tubing delivery device 500 is used to perform a first clamping and conveying operation on the heat shrink tubing 30 corresponding to the working position, enabling the heat shrink tubing delivery device 500 to convey the heat shrink tubing 30 to the first predetermined conduit position of the tubing guide device 600 for guiding and conveying. The heat shrink tubing cutting device 200 is used to cut the heat shrink tubing 30 after the first clamping and conveying operation to form a first heat shrink tubing 32.

[0040] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, the heat shrink tubing delivery device 500 is further configured to perform a second clamping and conveying operation on the heat shrink tubing 30 corresponding to the working position after the first cutting of the heat shrink tubing 30, so that the heat shrink tubing delivery device 500 can convey the heat shrink tubing 30 to the second predetermined conduit position of the tubing guide device 600 for guiding and conveying. The heat shrink tubing cutting device 200 is further configured to perform a second cutting on the heat shrink tubing 30 after the second clamping and conveying operation to form a second heat shrink tubing 34.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the tube guiding device 600 is used to guide and transport the heat shrink tubing 30 during the first clamping and conveying operation and the second clamping and conveying operation, respectively. See also... Figures 6 to 10Specifically, the first predetermined guide tube position of the tube-inserting guide device 600 guides and conveys the heat-shrinkable tubing 30 during the first clamping and conveying operation, and the second predetermined guide tube position of the tube-inserting guide device 600 guides and conveys the heat-shrinkable tubing 30 during the second clamping and conveying operation, so that the two ends of the bent wire 20 are inserted into the heat-shrinkable tubing at two different positions. In this way, the heat-shrinkable tubing 30 can be quickly and accurately conveyed into the tube-inserting guide device 600 during both the first and second clamping and conveying operations, and the first heat-shrinkable tubing 32 and the second heat-shrinkable tubing 34 are positioned.

[0042] like Figure 2 , Figure 3 and Figure 11 As shown, the wire-threading device 100 is used to feed both ends of the bent wire 20 into the tube-threading guide device 600, and to thread both ends of the bent wire 20 into the first heat-shrink tubing 32 and the second heat-shrink tubing 34 respectively. Since the first heat-shrink tubing 32 and the second heat-shrink tubing 34 are positioned within the tube-threading guide device 600, it prevents either the first heat-shrink tubing 32 or the second heat-shrink tubing 34 from slipping out of the tube-threading guide device 600 during the wire threading process. The heat-shrinking device 300 is used to perform heat-shrinking operations on the first heat-shrink tubing 32 and the second heat-shrink tubing 34 respectively, forming the heat-shrink tubing finished product 40.

[0043] In one embodiment, the specific operation steps of the above-mentioned multi-specification dual-through heat shrink tubing device 10 are as follows: First, the heat shrink tubing switching device 400 is activated to drive one type of heat shrink tubing 30 to the working position; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30 to be transported, i.e., the first predetermined conduit position, is controlled to move to the position corresponding to the working position; then, the heat shrink tubing feeding device 500 performs a first clamping and transporting operation on the heat shrink tubing 30 corresponding to the working position to deliver a heat shrink tubing 30 of a predetermined length into the first predetermined conduit position of the tubing guide device 600; then, the heat shrink tubing cutting device 200 cuts the heat shrink tubing 30 after the first clamping and transporting operation to form a first heat shrink tubing 32; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30 to be transported, i.e., the second predetermined conduit position, is controlled to move to the position corresponding to the working position. The work position is determined by the heat shrink tubing device 500, which performs a second clamping and conveying operation on the heat shrink tubing 30 corresponding to the work position, to deliver the heat shrink tubing 30 of a predetermined length to the second predetermined guide tube position of the tubing guide device 600. Then, the heat shrink tubing cutting device 200 cuts the heat shrink tubing 30 after the second clamping and conveying operation to form a second heat shrink tubing 34. Then, the wire clamping and threading device 100 conveys both ends of the bent wire 20 into the tubing guide device 600, and the two ends of the bent wire 20 are respectively threaded into the first heat shrink tubing 32 and the second heat shrink tubing 34. Then, the heat shrinking device 300 performs heat shrinking operations on the first heat shrink tubing 32 and the second heat shrink tubing 34 respectively to form a heat shrink tubing threaded product. Finally, the heat shrink tubing threaded product is taken out and unloaded, thus completing the process, and repeating the cycle.

[0044] The aforementioned multi-specification double-threading heat shrink tubing device 10 and heat shrink tubing switching device 400 can carry multiple heat shrink tubing materials 30 and switch one of them to the working position. This allows for adaptation according to the different tubing requirements at both ends of the bent wire 20, improving the applicability of the multi-specification double-threading heat shrink tubing device 10 and thus meeting the needs of automatically threading multiple heat shrink tubings. Since the threading guide device 600 guides and conveys the heat shrink tubing material 30 during the first clamping and conveying operation and the second clamping and conveying operation, the first heat shrink tubing 32 and the second heat shrink tubing 34 are positioned in the threading guide device 600. The wire clamping and threading device 100 conveys both ends of the bent wire 20 into the threading guide device 600 and threads both ends of the bent wire 20 into the first heat shrink tubing 32 and the second heat shrink tubing 34, respectively. This achieves the effect of simultaneously threading heat shrink tubing at both ends of the bent wire 20, thus improving the efficiency of threading heat shrink tubing. The aforementioned multi-specification double-thread heat shrink tubing equipment 10 not only improves the efficiency of heat shrink tubing threading but also reduces the manual labor intensity required for tubing threading, and enhances the applicability of the fully automatic heat shrink tubing threading machine.

[0045] like Figure 2 and Figure 11 As shown, the wire clamping and threading device 100 further includes a wire clamping and threading jaw 110, a jaw support 120, and a threading module 130. The wire clamping and threading jaw 110 is mounted on the jaw support 120, and the jaw support 120 is mounted on the power output end of the threading module 130, so that the threading module 130 drives the jaw support 120 to move in a predetermined direction. Furthermore, the wire clamping and threading jaw 110 includes a jaw drive cylinder 112, a first sliding jaw 114, and a second sliding jaw 116. The power output end of the jaw drive cylinder 112 is connected to the first sliding jaw 114 and the second sliding jaw 116 respectively. The jaw drive cylinder 112 drives the first sliding jaw 114 and the second sliding jaw 116 to move relative to each other, so that the first sliding jaw 114 and the second sliding jaw 116 together clamp or release the two ends of the bent wire 20. In this embodiment, the jaw drive cylinder 112 is a cylinder assembly or an electric cylinder assembly.

[0046] like Figure 2 and Figure 11 As shown, in one embodiment, the heat shrink tubing cutting device 200 is located between the tubing guide device 600 and the heat shrink tubing switching device 400, so that the heat shrink tubing cutting device 200 can better cut the heat shrink tubing 30 after clamping and conveying.

[0047] like Figure 2 and Figure 12As shown, the heat shrink tubing cutting device 200 further includes a scissor bracket 210, a lifting drive mechanism 220, a blade holder 230, a first blade 240, a second blade 250, a pusher block assembly 260, and a blade cylinder 270. The lifting drive mechanism 220 is mounted on the scissor bracket 210, the blade holder 230 is connected to the power output end of the lifting drive mechanism 220, the first blade 240 and the blade cylinder 270 are both mounted on the blade holder 230, the pusher block assembly 260 is slidably disposed on the blade holder 230, the first blade 240 and the second blade 250 are rotatably connected, one end of the pusher block assembly is connected to the power output end of the blade cylinder 270, and the other end of the pusher block assembly is slidably connected to the first blade 240 and the second blade 250 respectively. When the heat shrink tubing cutting device 200 needs to cut the heat shrink tubing 30, firstly, the lifting drive mechanism 220 drives the blade holder 230 to rise to a predetermined position. Then, the blade cylinder 270 drives the pusher block assembly to move, causing the pusher block assembly to slide relative to the first blade 240 and the second blade 250 respectively, so that the first blade 240 and the second blade 250 rotate relative to each other in an overlapping direction, thereby realizing the cutting operation of the heat shrink tubing 30. Then, the blade cylinder 270 returns to its original position. Then, the lifting drive mechanism 220 drives the blade holder 230 to descend to the starting position. Specifically, the end of the pusher block assembly 260 away from the blade cylinder is provided with an opening and closing slide column 261. The first blade 240 has a first guide groove 241, and the second blade 250 has a second guide groove (not shown). The opening and closing slide column passes through the second guide groove and the first guide groove respectively, so that the pusher block assembly 260 slides relative to the first blade 240 and the second blade 250 respectively.

[0048] like Figure 2 and Figure 12 As shown, the heat shrink tubing cutting device 200 further includes a blade shaft 280. The first blade 240 has a first rotating hole (not shown), and the second blade 250 has a second rotating hole (not shown). The blade shaft passes through the first and second rotating holes respectively, allowing the first blade 240 and the second blade 250 to be rotatably connected. In this embodiment, the first blade 240 and the second blade 250 are connected to the circular hole of the blade holder 230 via the blade shaft 280. The pusher block assembly 260 slides along the blade holder 230, causing the second blade 250 to open or close relative to the first blade 240 along the blade shaft 280 to cut the heat shrink tubing. The blade cylinder 270 is mounted on the blade holder 230 and pushes the pusher block assembly 260 to slide. Specifically, the lifting drive mechanism 220 is a scissor slide.

[0049] like Figure 2 and Figure 13As shown, the heat shrinking device 300 further includes a hot air gun 310, a Y-sliding block 320, a Y-sliding cylinder 330, an X-sliding block 340, an X-sliding cylinder 350, and a substrate 360. The Y-sliding block 320 is slidably disposed on the X-sliding block 340, and the Y-sliding cylinder 330 is mounted on the X-sliding block 340, with the power output end of the Y-sliding block 320 connected to the Y-sliding cylinder 330. The X-sliding block 340 is slidably connected to the substrate 360, and the X-sliding cylinder 350 is mounted on the substrate, with its power output end connected to the X-sliding block 340. The hot air gun 310 is mounted on the Y-sliding block 320, allowing the hot air gun to move relative to the substrate within the plane enclosed by the X and Y axes, thereby enabling the heat shrinking device 300 to better perform heat shrinking operations on the first heat shrink tube 32 and the second heat shrink tube 34 on the tube guide device 600.

[0050] like Figure 2 and Figure 13 As shown, the heat shrinking device 300 further includes a Y-linear guide rail 370, which is mounted on an X-sliding block 340. A Y-sliding block 320 is slidably connected to the Y-linear guide rail 370, and a Y-sliding cylinder 330 can drive the Y-sliding block 320 to move back and forth along the Y-linear guide rail 370. In this embodiment, the front position of the substrate is a clearance position to facilitate laser marking; there are two Y-linear guide rails 370, which are mounted on the X-sliding block 340. Furthermore, the heat shrinking device 300 also includes an X linear guide rail 380 disposed on the substrate, an X sliding block 340 slidably mounted on the X linear guide rail 380, and an X sliding cylinder 350 capable of driving the X sliding block 340 to move left and right. When the X sliding cylinder 350 drives the X sliding block 340 to move to the left end, the hot air gun performs a heat shrinking operation on the first heat shrink tube 32; conversely, when the X sliding cylinder 350 drives the X sliding block 340 to move to the right end, the hot air gun performs a heat shrinking operation on the second heat shrink tube 34.

[0051] like Figure 2 and Figure 4As shown, in one embodiment, the heat shrink tubing switching device 400 includes a switching bracket 410, a switching mechanism 420, a switching plate 430, a guide assembly 440, and a push guide mechanism 450. The switching mechanism 420 is mounted on the switching bracket 410, and the power output end of the switching mechanism 420 is connected to the switching plate 430. The guide assembly 440 is disposed on the switching plate 430 and has a plurality of guide holes 441, each guide hole being used to guide and support a corresponding heat shrink tubing 30. The guiding mechanism 450 includes a driving power source 452 and a sliding push tube assembly 454. The driving power source 452 is mounted and fixed on the switching plate 430, and the sliding push tube assembly 454 is slidably disposed on the switching plate 430. The sliding push tube assembly 454 includes multiple guide push tubes 4542, each guide push tube 4542 having a front guide hole 4543 formed therein. The front guide holes of the multiple guide push tubes 4542 correspond one-to-one with multiple fixed guide holes. The front guide hole of each guide push tube 4542 is used to guide the corresponding heat shrink tubing 30 through, so that the heat shrink tubing switching device 400 can carry multiple heat shrink tubing 30 and switch one of the heat shrink tubing 30 to the working position. In this embodiment, the driving power source 452 is a cylinder or an electric cylinder.

[0052] like Figure 2 and Figure 4 As shown, the heat shrink tubing switching device 400 further includes front and rear cylinders 460 and front and rear slide plates 470. The front and rear cylinders 460 are mounted on the switching bracket 410, and the front and rear slide plates 470 are slidably disposed on the switching bracket 410. The switching mechanism 420 is mounted and fixed on the side of the front and rear slide plates 470 opposite to the switching bracket 410. The power output end of the front and rear cylinders 460 is connected to the front and rear slide plates 470, so that the front and rear cylinders 460 drive the front and rear slide plates 470 to slide relative to the switching bracket 410 in the front-rear direction.

[0053] like Figure 2 and Figure 4 As shown, the sliding push tube assembly 454 further includes a mounting block 4544, which is slidably connected to the switching plate 430. Multiple guide push tubes 4542 are arranged side-by-side on the mounting block 4544. To improve the accuracy of the heat shrink tubing cutting device 200 in cutting the heat shrink tubing 30 each time, the sliding push tube assembly 454 further includes multiple clamping mechanisms 4546. Each clamping mechanism 4546 corresponds one-to-one with a multiple guide push tube 4542. Each clamping mechanism 4546 includes a clamping block 521, a guide post 522, a clamping block seat 523, a push block 524, and an elastic element 525. The clamping block seat 523 of each clamping mechanism 4546 is mounted on the mounting block 4544. In this embodiment, the mounting block 4544 has an exposed hole, and the clamping block seat 523 of each clamping mechanism 4546 is located within the exposed hole and fixedly connected to the mounting block 4544. The elastic element 525 can be a spring or elastic rubber.

[0054] like Figure 2 , Figure 4 and Figure 14 As shown, further, each guide push tube 4542 is installed in the circular hole of the clamping block seat 523 of the corresponding clamping mechanism 4546. The clamping block seat 523 has a sliding hole 5232, and the guide post passes through the sliding hole and is slidably connected to the clamping block seat. Specifically, each guide push tube 4542 has a notch (not shown), and the clamping block seat of each clamping mechanism 4546 forms a clearance opening 4547 communicating with the corresponding notch. The two ends of the guide post of each clamping mechanism 4546 are respectively connected to the corresponding clamping block 521 and the push block. The clamping block 521 of each clamping mechanism 4546 elastically abuts against the corresponding heat shrink tubing 10 through the clearance opening and the notch. The elastic element 525 of each clamping mechanism 4546 is sleeved on the corresponding guide post, and the two ends of the elastic element 525 of each clamping mechanism 4546 abut against the corresponding push block and the clamping block seat. The push block is located below the mounting block 4544. See also Figure 12 Furthermore, the heat shrink tubing cutting device 200 also includes an unlocking block 290 and an unlocking cylinder 295. The unlocking cylinder 295 is mounted on the scissor bracket 210, and its power output end is connected to the unlocking block 290. The unlocking cylinder 295 drives the unlocking block 290 to move up and down in the vertical direction. When heat shrink tubing needs to be transported, that is, when heat shrink tubing needs to be unlocked, the unlocking cylinder 295 drives the unlocking block 290 to move upward until the unlocking block 290 abuts against and pushes the push block upward. At this time, the elastic element is in a compressed state, causing the clamping block 521 to leave the heat shrink tubing, thus unlocking the heat shrink tubing. Conversely, when the heat shrink tubing delivery device 500 completes the delivery of the heat shrink tubing 30 of the predetermined length, the unlocking cylinder 295 drives the unlocking block 290 to move downwards. The elastic element automatically resets under its own elastic force, thereby driving the clamping block to move downwards until the clamping block abuts against the compression tube, realizing the delivery and locking operation of the compression tube, which improves the accuracy of the heat shrink tubing cutting device 200 in cutting the heat shrink tubing 30 each time.

[0055] See also Figure 4 and Figure 14 Furthermore, there are two guide posts and two elastic elements, with each elastic element correspondingly fitted onto one of the two guide posts. There are also two sliding holes, with each guide post slidingly inserted into one of the two sliding holes. The two ends of the pressure block are connected to one end of each of the two guide posts, and the two ends of the push block are connected to the other ends of each of the two guide posts, allowing the pressure block to better elastically support the heat shrink tubing.

[0056] See also Figure 4 and Figure 14Furthermore, the guide assembly 440 includes a fixing block 442 and multiple guide tubes 444. The fixing block 442 is mounted on the switching plate 430 and has multiple through holes. The multiple guide tubes 444 are installed one-to-one in the multiple through holes. The multiple guide tubes 444 are correspondingly arranged with multiple guide push tubes 4542. Multiple heat-shrinkable tubing 30 is respectively inserted through the multiple guide tubes 444 and the multiple guide push tubes 4542. Multiple guide holes are correspondingly formed in the multiple guide tubes 444. There is a clamping conveying area between each guide tube 444 and the corresponding guide push tube 4542. The heat shrink tubing delivery device 500 is used to perform a first clamping and conveying operation on the heat shrink tubing 30 corresponding to the working position in the clamping and conveying area, and after cutting the heat shrink tubing 30 once, it performs a second clamping and conveying operation on the heat shrink tubing 30 corresponding to the working position in the clamping and conveying area, so that the heat shrink tubing delivery device 500 can convey the heat shrink tubing 30, and at the same time make the structure of the multi-specification double-through heat shrink tubing equipment 10 more compact.

[0057] See also Figure 2 and Figure 5In one embodiment, the heat shrink tubing delivery device 500 includes a tubing delivery support assembly 510, an active support 520, a driven support 530, an active wheel 540, a driven wheel 550, a tubing delivery drive 560, and a centering gripper 570. The active support 520 and the driven support 530 are slidably disposed on the tubing delivery support assembly 510. The tubing delivery drive 560 is mounted on the active support 520. The active wheel 540 is rotatably connected to the active support 520, and the driven wheel 550 is rotatably connected to the driven support 530. The power output shaft of the tubing delivery drive 560 is connected to the active wheel 540. The tubing delivery drive 560 drives the active wheel 540 to rotate, the driven wheel 550 is rotatably connected to the driven support 530, and the centering gripper 570 is mounted on the tubing delivery support assembly 510. The centering gripper 570 drives the active support 520 and the driven support 530 to move closer or further apart. In this configuration, when the active support 520 and the driven support 530 approach each other, the active wheel 540 and the driven wheel 550 clamp the heat-shrinkable tubing 30 together. When a first clamping and conveying operation or a second clamping and conveying operation of the heat-shrinkable tubing 30 is required, the active support 520 and the driven support 530 are first driven closer together by the centering gripper 570, allowing the active wheel 540 and the driven wheel 550 to work together on the heat-shrinkable tubing 30. Then, the tubing delivery drive 560 is activated, driving the active wheel 540 to rotate. At this time, the main delivery wheel and the driven wheel 550 work together on the heat-shrinkable tubing 30 to convey a predetermined length of heat-shrinkable tubing 30. Then, the centering gripper 570 drives the active support 520 and the driven support 530 away from each other, thus completing the conveying of the heat-shrinkable tubing 30. In this embodiment, the tubing delivery drive 560 is a tubing delivery motor or a tubing delivery cylinder. The centering gripper 570 drives the active support 520 to move relative to the driven support 530 along the Z-axis. Both the active support 520 and the driven support 530 are equipped with sliders, and the tube feeding support assembly 510 is equipped with guide rails. The sliders of the active support 520 or the driven support 530 are slidably engaged on the guide rails, so that the active support 520 and the driven support 530 can be well slidably connected to the tube feeding support assembly 510.

[0058] See also Figure 2 and Figure 6 In one embodiment, the tube guiding device 600 includes a guide support assembly 610, a guide stop mechanism 620, and an opening and closing drive mechanism 630. The guide stop mechanism 620 includes a first guide stop component 622 and a second guide stop component 624. Both the first guide stop component 622 and the second guide stop component 624 are movably disposed on the guide support assembly 610, and both the first guide stop component 622 and the second guide stop component 624 are connected to the power output end of the opening and closing drive mechanism 630. The opening and closing drive mechanism 630 is used to drive the first guide stop component 622 and the second guide stop component 624 to open or close relative to each other.

[0059] See also Figure 2 , Figure 6 , Figure 7 and Figure 8 Furthermore, the first guide stop assembly 622 and the second guide stop assembly 624 together form a first positioning anti-detachment groove 623a and a second positioning anti-detachment groove 623b spaced apart. The first positioning anti-detachment groove 623a is used to guide and transport the heat shrink tubing 30 during the first clamping and conveying operation, and to position the first heat shrink tubing 32 when one end of the bent wire 20 is inserted into the first heat shrink tubing 32, thus preventing the first heat shrink tubing 32 from slipping off the tubing guide device 600 during wire insertion. The second positioning anti-detachment groove 623b is used to guide and transport the heat shrink tubing 30 during the second clamping and conveying operation, and to position the second heat shrink tubing 34 when the other end of the bent wire 20 is inserted into the second heat shrink tubing 34, thus preventing the second heat shrink tubing 34 from slipping off the tubing guide device 600 during wire insertion.

[0060] See also Figure 2 , Figure 4 and Figure 6 Furthermore, the sliding pusher assembly 454 is used to guide the heat shrink tubing 30 during the first clamping and conveying operation, and to guide the heat shrink tubing 30 during the second clamping and conveying operation. Even further, the sliding pusher assembly 454 is also used to simultaneously push the first heat shrink tubing 32 and the second heat shrink tubing 34 into the tubing guide device 600 after the second cutting of the heat shrink tubing 30. That is, after the second cutting of the heat shrink tubing 30, the first heat shrink tubing 32 is pushed into the first positioning tubing anti-detachment groove 623a, and the second heat shrink tubing 34 is pushed into the second positioning tubing anti-detachment groove 623b, so that the wire clamping and threading device 100 can better thread the two ends of the bent wire 20 into the first heat shrink tubing 32 and the second heat shrink tubing 34 respectively.

[0061] See also Figure 2 , Figure 4 and Figure 6In one embodiment, a first wire-through guide groove 623c and a second wire-through guide groove 623d are jointly formed between the first guide stop assembly 622 and the second guide stop assembly 624. The first wire-through guide groove 623c communicates with the first positioning tube anti-detachment groove 623a, and the second wire-through guide groove 623d communicates with the second positioning tube anti-detachment groove 623b. The first wire-through guide groove 623c is used to guide the bent wire 20 when one end of the bent wire 20 is inserted into the first heat shrink tubing 32, thereby improving the efficiency of the first heat shrink tubing 32 in inserting the bent wire 20. The second wire-through guide groove 623d is used to guide the bent wire 20 when the other end of the bent wire 20 is inserted into the second heat shrink tubing 34, thereby improving the efficiency of the second heat shrink tubing 34 in inserting the bent wire 20.

[0062] like Figure 6 and Figure 7 As shown, the first guide stop assembly 622 further includes a first guide piece 6221 and a first heat shrink tubing upper baffle 6225 connected to each other, and the second guide stop assembly 624 includes a second guide piece 6241 and a second heat shrink tubing upper baffle 6245 connected to each other. The first guide piece 6221 and the second guide piece 6241 are correspondingly arranged, and the first heat shrink tubing upper baffle 6225 and the second heat shrink tubing upper baffle 6245 are correspondingly arranged. Both the first guide piece 6221 and the second guide piece 6241 are slidably disposed on the guide bracket assembly 610. Furthermore, the guide bracket assembly 610 forms an exposed opening 611, and the guide bracket assembly 610 is provided with two guide rails 613 protruding from it, with the exposed opening 611 located between the two guide rails 613. The first guide plate 6221 includes a first guide plate body 6222, a first guide post 6223, and a first sliding block 6224. The first guide plate body 6222 is connected to the upper baffle 6225 of the first heat shrink tubing, the first guide post 6223, and the first sliding block 6224, respectively. The first guide post 6223 and the first sliding block 6224 are located on both sides of the first guide plate body 6222. The second guide plate 6241 includes a second guide plate body 6242, a second guide post 6243, and a second sliding block (not shown). The second guide plate body 6242 is connected to the upper baffle 6245 of the second heat shrink tubing, the second guide post 6243, and the second sliding block, respectively. The second guide post 6243 and the second sliding block are located on both sides of the second guide plate body 6242.

[0063] like Figure 6 and Figure 7As shown, in this embodiment, there are two of each of the following: the first guide post 6223, the first sliding block 6224, the second guide post 6243, and the second sliding block. The two first sliding blocks 6224 are slidably disposed on the two guide rails 613, and the two second sliding blocks are slidably disposed on the two guide rails 613. The power output end of the opening / closing drive mechanism 630 has two first inclined guide grooves 632 and two second inclined guide grooves 634. The two first guide posts 6223 are slidably disposed on the two first inclined guide grooves 632, and the two second guide posts 6243 are slidably disposed on the two second inclined guide grooves 634. Each first inclined guide groove 632 is opposite to the corresponding second inclined guide groove 634. When the opening / closing drive mechanism 630 is activated, the power output end of the opening / closing drive mechanism 630 slides relative to the two first guide posts 6223 and the two second guide posts 6243, thereby causing the first guide plate body 6222 and the second guide plate body 6242 to move closer to or further away from each other. When the bent wire 20 needs to be guided and threaded, the power output end of the opening and closing drive mechanism 630 is activated, driving the first guide plate body 6222 and the second guide plate body 6242 to approach and abut against each other, so that there is an abutment surface between the first guide plate body 6222 and the second guide plate body 6242. The inclined direction of the extension of each first inclined guide groove 632 and the inclined direction of the extension of the corresponding second inclined guide groove 634 are symmetrically arranged along the abutment surface. The first positioning tube threading anti-detachment groove 623a and the second positioning tube threading anti-detachment groove 623b are both connected to the exposed opening 611. When the first guide plate body 6222 and the second guide plate body 6242 abut and close, the first wire tube guide groove 623c is used to guide and transport the heat shrink tubing 30 during the first clamping and conveying operation, and the second wire tube guide groove 623d is used to guide and transport the heat shrink tubing 30 during the second clamping and conveying operation. At the same time, the first heat shrink tubing upper baffle 6225 and the second heat shrink tubing upper baffle 6245 abut and close. At this time, the first positioning tube anti-detachment groove 623a is used to position the first heat shrink tubing 32 when one end of the bent wire 20 is inserted into the first heat shrink tubing 32, and the second positioning tube anti-detachment groove 623b is used to position the second heat shrink tubing 34 when the other end of the bent wire 20 is inserted into the second heat shrink tubing 34.

[0064] like Figure 6 and Figure 7As shown, the opening and closing drive mechanism 630 further includes a guide cylinder 631 and a sliding block 633. The guide cylinder 631 is mounted on the guide bracket assembly 610, and the sliding block 633 is slidably connected to the guide bracket assembly 610, and the sliding block 633 is connected to the power output end of the guide cylinder 631. Two first inclined guide grooves 632 and two second inclined guide grooves 634 are all formed on the sliding block 633. In this embodiment, the power output direction of the guide cylinder 631 is at an angle to the output direction of the guide rail 613. In addition, the inclined direction of the extension of each first inclined guide groove 632 and the inclined direction of the extension of the corresponding second inclined guide groove 634 are symmetrically arranged along the abutment surface, so that the guide cylinder 631 can make the first guide plate body 6222 and the second guide plate body 6242 move closer or further apart during the sliding of the sliding block 633 relative to the guide bracket assembly 610.

[0065] like Figure 6 and Figure 7 As shown, the guide bracket assembly 610 further includes a guide bracket 611, a replication guide rail 613, a bracket slide 615, and a moving module 617. The replication guide rail 613 is disposed on the guide bracket 611, the moving module 617 is mounted on the guide bracket 611, and the bracket slide 615 is slidably disposed on the replication guide rail 613. The bracket slide 615 is connected to the power output end of the moving module 617, so that the moving module 617 drives the bracket slide 615 to slide relative to the replication guide rail 613. In this embodiment, the guide cylinder 631 and the two guide rails 613 are both disposed on the bracket slide 615, and the exposed opening 611 is formed in the bracket slide 615.

[0066] like Figure 6 As shown, further, the first wire conduit guide groove 623c includes a first wire conduit upper guide groove formed on the first guide piece 6221 and a first wire conduit lower guide groove formed on the second guide piece 6241, the first wire conduit upper guide groove and the first wire conduit lower guide groove being connected. The second wire conduit guide groove 623d includes a second wire conduit upper guide groove formed on the first guide piece 6221 and a second wire conduit lower guide groove formed on the second guide piece 6241, the second wire conduit upper guide groove and the second wire conduit lower guide groove being connected. In this embodiment, there are multiple first positioning conduit anti-detachment grooves 623a, second positioning conduit anti-detachment grooves 623b, first wire conduit guide grooves 623c and second wire conduit guide grooves 623d. Multiple first positioning conduit anti-detachment grooves 623a are connected to multiple first wire conduit guide grooves 623c in a one-to-one correspondence, and multiple second positioning conduit anti-detachment grooves 623b are connected to multiple second wire conduit guide grooves 623d in a one-to-one correspondence.

[0067] like Figure 6 , Figure 9 and Figure 10As shown, both the first positioning tube insertion anti-detachment groove 623a and the second positioning tube insertion anti-detachment groove 623b are conical grooves. The diameter of the first positioning tube insertion anti-detachment groove 623a adjacent to the sliding push tube assembly 454 is smaller than the diameter away from the sliding push tube assembly 454, and the diameter of the second positioning tube insertion anti-detachment groove 623b adjacent to the sliding push tube assembly 454 is smaller than the diameter away from the sliding push tube assembly 454.

[0068] like Figure 2 and Figure 15 As shown, in one embodiment, the multi-specification double-thread heat shrink tubing equipment 10 further includes a tubing guide device 700. The tubing guide device 700 clamps both ends of the bent wire 20 and guides both ends of the bent wire 20 into the tubing guide device 600. This allows the two ends of the bent wire 20 to be quickly and accurately fed into the tubing guide device 600 via the clamping and threading device 100, and to be quickly and reliably threaded into the first heat shrink tubing 32 and the second heat shrink tubing 34, respectively. This is particularly beneficial for bent wires made of flexible materials, enabling the multi-specification double-thread heat shrink tubing equipment 10 to achieve flexible multi-specification production capabilities. The tubing guide device can straighten the flexible wire, ensuring the controllability and stability of the tubing position. Thus, this device can adapt to product diversity and small-batch production, and can be used for the automated production of flexible wires.

[0069] like Figure 2 and Figure 15 As shown, in one embodiment, the conduit guide device 700 includes a first base 710, a moving mechanism 720, a gripper mounting block 730, a guide drive assembly 740, and a guide gripper assembly 750. The moving mechanism 720 is disposed on the first base 710, and the gripper mounting block 730 is connected to the power output shaft of the moving mechanism 720, enabling the moving mechanism 720 to drive the gripper mounting block 730 to move in three-dimensional space. The guide drive assembly 740 is mounted on the gripper mounting block 730, and the guide gripper assembly 750 is connected to the power output end of the guide drive assembly 740, driving the guide gripper assembly 750 to open or close. The guide gripper assembly 750 is used to clamp both ends of the bent wire 20 and guide both ends of the bent wire 20 into the conduit guide device 600.

[0070] like Figure 2 and Figure 15As shown, in one embodiment, the moving mechanism 720 includes a moving drive 722, a mounting slide 724, and a lifting drive 726. The moving drive 722 is mounted on the first base 710, and the mounting slide 724 is located at the power output end of the moving drive 722, causing the moving drive 722 to drive the mounting slide 724 to slide along a first direction. The lifting drive 726 is mounted on the mounting slide 724, and a gripper mounting block 730 is fixedly connected to the power output shaft of the lifting drive 726, causing the lifting drive 726 to drive the gripper mounting block 730 to slide along a second direction, which forms an angle with the first direction. In this embodiment, the first direction and the second direction are perpendicular to each other. Specifically, the first direction is the X-axis direction, and the second direction is the Y-axis direction. In other embodiments, the first direction and the second direction are not limited to being perpendicular to each other.

[0071] like Figure 2 and Figure 15 As shown, in one embodiment, the guide rail gripper assembly 750 includes a first double semi-circular gripper 752 and a second double semi-circular gripper 754. The first double semi-circular gripper 752 and the second double semi-circular gripper 754 are both fixedly connected to the guide rail drive assembly 740. The first double semi-circular gripper 752 has a first left semi-circular gripping groove 7522 and a second left semi-circular gripping groove 7524. The second double semi-circular gripper 754 has a first right semi-circular gripping groove 7542 and a second right semi-circular gripping groove 7544. The first left semi-circular gripping groove 7522 and the first right semi-circular gripping groove 7542 are arranged opposite to each other, and the second left semi-circular gripping groove 7524 and the second right semi-circular gripping groove 7544 are arranged opposite to each other. The guide line drive assembly 740 is used to drive the first double semicircular claw 752 and the second double semicircular claw 754 to move relative to each other, so that the first left semicircular clamping groove 7522 and the first right semicircular clamping groove 7542 move closer or further away from each other, and the second left semicircular clamping groove 7524 and the second right semicircular clamping groove 7544 move closer or further away from each other.

[0072] When the guide wire drive assembly 740 drives the first double semicircular claw 752 and the second double semicircular claw 754 to move relative to each other in the positive direction, the first left semicircular clamping groove 7522 and the first right semicircular clamping groove 7542 approach each other, and the second left semicircular clamping groove 7524 and the second right semicircular clamping groove 7544 approach each other. At this time, the guide wire clamping claw assembly 750 is in a closed state, so as to clamp and transport both ends of the bent wire 20 simultaneously. When the guide wire drive assembly 740 drives the first double semicircular claw 752 and the second double semicircular claw 754 to move relative to each other in the opposite direction, the first left semicircular clamping groove 7522 and the first right semicircular clamping groove 7542 move away from each other, and the second left semicircular clamping groove 7524 and the second right semicircular clamping groove 7544 move away from each other. At this time, the guide wire clamping claw assembly 750 is in an open state. In this embodiment, the guide line drive assembly 740 drives the first double semi-circular claw 752 to move relative to the second double semi-circular claw 754 along a third direction, which forms an angle with both the first and second directions. Specifically, the third direction is perpendicular to both the first and second directions, and the first and second directions are perpendicular to each other.

[0073] Furthermore, the guide cable drive assembly 740, the lifting drive component 726, and the moving drive component 722 are all cylinder assemblies. In other embodiments, the guide cable drive assembly 740, the lifting drive component 726, and the moving drive component 722 can also be electric cylinder assemblies.

[0074] like Figure 2 and Figure 15 As shown, the first double semi-circular claw 752 further includes a first left semi-circular claw 752a, a first claw body 752b, and a first right semi-circular claw 752c connected in sequence. A first left semi-circular groove 7522 is formed on the side of the first left semi-circular claw 752a adjacent to the first right semi-circular claw 752c, and a first right semi-circular groove 7542 is formed on the side of the first right semi-circular claw 752c opposite to the first left semi-circular claw 752a. The second double semi-circular claw 754 includes a second left semi-circular claw 754a, a second claw body 754b, and a second right semi-circular claw 754c connected in sequence. A second left semi-circular groove 7524 is formed on the side of the second left semi-circular claw opposite to the second right semi-circular claw, and a second right semi-circular groove 7544 is formed on the side of the second right semi-circular claw adjacent to the second left semi-circular claw. In this embodiment, both the first double semi-circular claw 752 and the second double semi-circular claw 754 are U-shaped.

[0075] like Figure 2As shown, in one embodiment, the multi-specification double-thread heat shrink tubing device 10 further includes a transfer device 800. The transfer device 800 is used to load the bent wire 20 before tubing to the wire clamping and threading device 100, and to unload the heat shrink tubing finished product 40 from the wire clamping and threading device 100. This allows the transfer device 800 to clamp and transport the bent wire 20.

[0076] The specific operating steps of the multi-specification double-through heat shrink tubing device 10 described above are as follows: First, the heat shrink tubing switching device 400 is activated, driving one type of heat shrink tubing 30 to the working position; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30, i.e., the first predetermined guide tube position, is moved to the position corresponding to the working position; then, the heat shrink tubing feeding device 500 performs a first clamping and feeding operation on the heat shrink tubing 30 corresponding to the working position to feed a heat shrink tubing 30 of a predetermined length into the first predetermined guide tube position of the tubing guide device 600; then, the heat shrink tubing cutting device 200 cuts the heat shrink tubing 30 after the first clamping and feeding operation to form a first heat shrink tubing 32; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30, i.e., the second predetermined guide tube position, is moved to the position corresponding to the working position; then, the heat shrink tubing feeding device 500 performs a second clamping and feeding operation on the heat shrink tubing 30 corresponding to the working position to feed a heat shrink tubing of a predetermined length. The tubing 30 is placed into the second predetermined conduit position of the tubing guide device 600; then, the heat shrink tubing 30 after the second clamping and conveying operation is cut by the heat shrink tubing cutting device 200 to form the second heat shrink tubing 34; then, the bent wire 20 before tubing is fed to the wire clamping and threading device 100; then, the wire clamping and threading device 100 is used to convey both ends of the bent wire 20 into the tubing guide device 600, while the tubing guide device 700 guides the bent wire 20 to the tubing guide device 600. The tube guide device 600 guides the two ends of the bent wire 20 through the first heat shrink tube 32 and the second heat shrink tube 34 respectively; then the heat shrink device 300 performs heat shrinking operation on the first heat shrink tube 32 and the second heat shrink tube 34 respectively to form the heat shrink tube threaded product 40; then the heat shrink tube threaded product 40 is transported to the transfer device 800 through the tube guide device 600; finally, the heat shrink tube threaded product 40 is taken out and unloaded by the transfer device 800, thus completing the process, and repeating the cycle.

[0080] In one embodiment, the specific operation steps of the multi-specification dual-thread heat shrink tubing device 10 are as follows: First, the heat shrink tubing switching device 400 is activated to drive one type of heat shrink tubing 30 to the working position; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30, i.e., the first predetermined conduit position, is moved to a position corresponding to the working position; then, the heat shrink tubing feeding device 500 performs a first clamping and feeding operation on the heat shrink tubing 30 corresponding to the working position to feed a heat shrink tubing 30 of a predetermined length into the first predetermined conduit position of the tubing guide device 600; then, the heat shrink tubing cutting device 200 cuts the heat shrink tubing 30 after the first clamping and feeding operation to form a first heat shrink tubing 32; then, the part of the tubing guide device 600 that guides the heat shrink tubing 30, i.e., the second predetermined conduit position, is moved to a position corresponding to the working position; then, the heat shrink tubing feeding device 500 performs a second clamping and feeding operation on the heat shrink tubing 30 corresponding to the working position to feed a heat shrink tubing 30 of a predetermined length into the second predetermined conduit position of the tubing guide device 600. The heat shrink tubing 30 after the second clamping and conveying operation is cut by the heat shrink tubing cutting device 200 to form the second heat shrink tubing 34; then the first heat shrink tubing 32 and the second heat shrink tubing 34 of the tubing guide device 600 are marked by the marking device 900; then the bent wire 20 before tubing is fed to the wire clamping and threading device 100; then the wire clamping and threading device 100 is used to convey both ends of the bent wire 20 into the tubing guide device 600, while the tubing guide device 7... The bent wire 20 is guided to the tube guide device 600, and both ends of the bent wire 20 are respectively inserted into the first heat shrink tube 32 and the second heat shrink tube 34; then the heat shrink device 300 is used to heat shrink the first heat shrink tube 32 and the second heat shrink tube 34 respectively to form the heat shrink tube threaded product 40; then the heat shrink tube threaded product 40 is transported to the transfer device 800 through the tube guide device 600; finally, the heat shrink tube threaded product 40 is taken out by the transfer device 800 and unloaded, thus completing the process, and repeating the cycle.

[0081] like Figures 6 to 8 As shown, in one embodiment, both the first positioning tube anti-detachment groove 623a and the second positioning tube anti-detachment groove 623b are exposed grooves, that is, a part of the first positioning tube anti-detachment groove 623a and a part of the second positioning tube anti-detachment groove 623b are formed with openings facing the marking device 900, so that the first heat shrink tube 32 positioned in the first positioning tube anti-detachment groove 623a and the second heat shrink tube 34 positioned in the second positioning tube anti-detachment groove 623b can be marked by the marking device 900.

[0082] like Figures 2 to 15 As shown, the specific operating steps of the above-mentioned multi-specification double-through heat shrink tubing device 10 are as follows:

[0083] First, the tubing guide device 600 activates, i.e., the guide cylinder 631 retracts, the sliding block 633 moves to the right, and the grippers composed of the first guide plate 6221 and the second guide plate 6241 open. Then, the heat shrink tubing switching device 400 activates, i.e., the switching mechanism 420 switches one of the three selected heat shrink tubing types to the working position. Then, the moving module 617 controls the guide device to reach the first exposed slot corresponding to the selected heat shrink tubing type in the working position. Then, the front and rear cylinders 460 extend, and the three guide push tubes mounted on the switching mechanism 420 push forward, with the guide push tubes touching the rear of the tubing guide device 600. Then, the centering gripper 570 closes, driving the driving wheel 540 and the driven wheel 550 to close, clamping the heat shrink tubing between the guide push tube and the fixed guide assembly 440. The tubing delivery drive 560 controls the tubing delivery driving wheel 540 to deliver a section of heat shrink tubing into the first exposed slot. Then, the driving wheel 540 and the driven wheel 550... The cylinders 460 and 460 extend and retract. Then, the lifting drive mechanism 220 moves the cutter head upwards, and the blade cylinder 270 pulls the second blade 250 to close relative to the first blade 240 to cut the heat shrink tubing. Then, the moving module 617 controls the guide device to the second exposed slot corresponding to the selected heat shrink tubing type. Then, the drive wheel 540 and driven wheel 550 close to clamp the heat shrink tubing and send a section of it into the second exposed slot. Then, the drive wheel 540 and driven wheel 550 open, and the cylinders 460 and 460 extend and retract. Then, the lifting drive mechanism 220 moves the cutter head upwards, and the blade cylinder 270 pulls the second blade 250 to close relative to the first blade 240 to cut the heat shrink tubing. Then, the power source 452 extends, pushing the sliding pusher assembly 454 forward. The two guide pushers 4542 of the sliding pusher assembly 454 completely push the cut portion exposed outside the exposed slot into the slot.

[0084] Then, the guide cylinder 631 extends, the sliding block 633 moves to the left, the first guide plate 6221 and the second guide plate 6241 close relative to each other, the first heat shrink tube 32 and the second heat shrink tube 34 are clamped between the first guide stop assembly 622 and the second guide stop assembly 624, and the first heat shrink tube 32 is partially exposed in the first exposed groove, and the second heat shrink tube 34 is partially exposed in the second exposed groove; then the marking device 900, i.e., the laser marking machine 9, marks the contents on the exposed part of the exposed groove; then the jaws of the transfer device 800 clamp the wire upward; then the wire clamping and threading device 100 is activated, i.e., the wire clamping and threading jaws 110 clamp the front end of the transfer device 800 of the bent wire 20, i.e., the U-shaped wire, at this time the threading and threading device 700's threading jaw assembly 750 is in the open state; then the lifting drive component Under the action of 726, the drive mounting slide 724 is raised; then the wire clamp assembly 750 closes, clamping the rear U-shaped wire of the transfer device 800 in the wire clamp assembly 750; then the power output end of the moving drive 722 moves towards the tube guide device 600, guiding the two ends of the U-shaped wire to the two tube guide grooves of the tube guide device 600, namely the first wire tube guide groove 623c and the second wire tube guide groove 623d respectively; then the wire clamping and threading clamp 110, driven by the threading module 130, makes the two ends of the wire pass through the tube guide device 700 and the two tube guide grooves respectively into the first heat shrink tube 32 and the second heat shrink tube 34, until they pass through the first positioning tube anti-detachment groove 623a and the second positioning tube anti-detachment groove 623b.

[0085] Then, the hot air gun 310 of the heat shrinking device 300 is turned on to blow air; then, the Y sliding cylinder 330 retracts, driving the air outlet 711 of the hot air gun 310 to move along the first heat shrink tube 32 of the exposed groove while blowing hot air to complete the heat shrinking; then, the X sliding cylinder 350 changes from extension to retraction, driving the air outlet 711 of the hot air gun 310 to move along the second heat shrink tube 34 of the exposed groove while blowing hot air to complete the heat shrinking. At this time, the Y sliding cylinder 330 extends, and during the process, hot air blows along the heat shrink tube once to complete the heat shrinking operation of the heat shrink tube; then, the guide cylinder 631 retracts, causing the sliding block 633 to move to the right, and the first guide plate 6221 and the second guide plate 6241 move away from each other and open; then, the wire threading module 130 causes the wire clamping and threading claw 110 to thread the heat shrink tube and the heat-shrinked bent wire 20 to return to the position of the transfer device 800, completing the process of multi-specification double-threading heat shrink tube, and repeating the cycle in sequence.

In this way, it can be adapted according to the requirements of different tubing materials at both ends of the bent wire 20, thus improving the applicability of the multi-specification double-thread heat shrink tubing equipment 10 and adapting to the needs of automatic threading of multiple heat shrink tubing materials.

[0088] 2. In the above-mentioned multi-specification double-threading heat shrink tubing equipment 10, the tubing guide device 600 guides and conveys the heat shrink tubing 30 during the first clamping and conveying operation and the second clamping and conveying operation, so that the first heat shrink tubing 32 and the second heat shrink tubing 34 are positioned in the tubing guide device 600. The wire clamping and threading device 100 conveys both ends of the bent wire 20 into the tubing guide device 600, and makes the two ends of the bent wire 20 pass through the first heat shrink tubing 32 and the second heat shrink tubing 34 respectively, thus achieving the effect of simultaneously threading heat shrink tubing at both ends of the bent wire 20, that is, achieving the effect of double-threading heat shrink tubing at both ends of the bent wire 20, thereby improving the efficiency of threading heat shrink tubing.

[0089] 3. The above-mentioned multi-specification double-thread heat shrink tubing equipment 10 not only improves the efficiency of heat shrink tubing threading, but also reduces the manual labor intensity required for tubing threading, and improves the applicability of the fully automatic heat shrink tubing threading machine.
