[0002] A large number of air pipes are distributed on the electrical automation equipment to supply air for electrical elements such as electromagnetic valves. If a large number of air pipes are not fixed by bundling, they are not only not beautiful, but also will be shaken due to repeated changes in air pressure, which will affect the sealing life of the connection between the air pipe and the pipe joint and will affect the movement of the surrounding moving structure. The traditional bundling method is to manually bundle with a rolling tape or adhesive tape, such as bundling the air pipes on the aluminum profile of the rack or bundling multiple air pipes together. When manually bundling, the force control of bundling one or several air pipes is entirely based on experience. If the force is too large, it will cause serious air pipe extrusion deformation, affecting the internal air pressure balance, and will cause air pipe rupture under long-term work.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0018] As shown in Figures 1-11 the present application provides: The air pipe sliding bundling device comprises a handle 10, a bundling mechanism 20, a guiding bundling arm 30 and a translation overturning mechanism 40, the handle 10 comprises a handle part and a mounting platform fixed on the handle part, the guiding bundling arm 30 is slidingly connected to the mounting platform, a guide groove is arranged on the handle part, the bundling mechanism 20 is located between the handle part and the guiding bundling arm 30 and is hingedly connected to the end of the guiding bundling arm 30, the translation overturning mechanism 40 is assembled on the mounting platform of the handle 10 and is used for driving the overturning of the sending bundling component 21 and the bending of the plurality of movable segments 32 so that the sending bundling component 21 and the guiding bundling arm 30 are pushed to translate away from the rolling belt after the rolling belt is connected at the head and tail; in use, the guiding bundling arm 30 is inserted under the air pipe bundle or the object carrying the air pipe which needs to be bundled by holding the handle part, the rolling belt is inserted into the guiding bundling arm 30 through the guide groove, and the guiding bundling arm 30 is bent while the bundling mechanism 20 is overturned, so that the rolling belt is connected at the head and tail.

[0019] Specifically, the bundling mechanism 20 comprises a sending bundling component 21, a fastening component 22 and a driving component 23, the sending bundling component 21 comprises a collecting frame 211 and a collecting module for collecting bundling data, the collecting module is fixed on the side of the collecting frame 211 facing the air pipe, that is, in the process of bundling, the collecting frame 211 can drive the collecting module to contact the air pipe, the collecting frame 211 is slidingly connected to the fastening component 22, the fastening component 22 comprises a connecting frame 221 and a fastening guide roller 222 rotationally connected to the connecting frame 221, the fastening guide roller 222 is at least two, the collecting frame 211 is slidingly connected to the connecting frame 221, and the driving component 23 is assembled on the connecting frame 221 and is used for driving the rotation of the fastening guide roller 222 to fasten the rolling belt.

[0020] The control unit is assembled on the handle part of the handle 10, the control unit comprises an analysis module and a control module, the analysis module, the control module, the collecting module and the driving component 23 are connected through wired and / or wireless connection, it should be noted that the power supply of the analysis module, the control module, the collecting module, the driving component 23 and the translation overturning mechanism 40 can be achieved by connecting to the mains or a storage battery, for example, a storage battery power supply mode, the storage battery and the required power supply module are built-in in the handle part of the handle 10, the charging mode is adopted to supplement the power of the storage battery, the control start-stop switch of the driving component 23 and the translation overturning mechanism 40 can be assembled on the handle part of the handle 10, the collecting module of the embodiment adopts a pressure sensor and a distance sensor, the specific installation position, model and circuit mode are determined by the person skilled in the art according to the actual situation, which is not limited here; Further, the analysis module is configured to receive the bundling data and determine whether to generate the start-stop instruction based on the bundling data. The bundling data includes a pressure value and a distance value. The pressure value can be used to determine the bundling force on the trachea. Since the collection module is located on the side of the tightening assembly 22, as the strap is tightened, the trachea is closer to the collection frame 211, thereby indirectly determining the tightening force of the strap. In some embodiments, the collection module is not limited to being installed on the collection frame 211, but can be installed at a position that does not affect the bundling work and can reflect the change in the bundling force. The distance value reflects the distance between the trachea and the collection frame 211, thereby avoiding misjudgment. Preferably, the analysis module determines whether to generate the start-stop instruction based on the following method: comparing the pressure value and the distance value with a preset pressure threshold and a preset distance threshold; if the pressure value is greater than or equal to the preset pressure threshold and the distance value is less than or equal to the preset distance threshold, it is determined that the bundling is qualified, and a stop instruction is generated; if the pressure value is greater than or equal to the preset pressure threshold and the distance value is greater than the preset distance threshold, it is determined that the bundling is abnormal, and a stop instruction and an alarm instruction are generated; if the pressure value is less than the preset pressure threshold and the distance value is greater than the preset distance threshold, it is determined that the bundling is in progress, and no stop instruction is generated, indicating that the target has not been reached, and the tightening continues. It is still in the bundling process and does not stop working; if the pressure value is less than the preset pressure threshold and the distance value is less than the preset distance threshold, it is determined that the bundling is abnormal, and an alarm instruction is generated, indicating that there is an obstruction problem with the distance collection sensor. The preset pressure threshold and the preset distance threshold are set by a person skilled in the art according to the actual situation and a large number of experiments, and are not limited here. The specific control logic is as follows: when the user presses the start-stop switch of the driving assembly 23, the bundling enters the state, the driving assembly 23 drives the strap to slowly tighten, and the collection module collects the pressure value and the distance value in real time. The analysis module continuously analyzes the pressure value and the distance value. When the pressure value reaches or exceeds the lower limit of the pressure threshold, and the distance value is less than or equal to the upper limit of the preset distance threshold, and the condition remains unchanged within a continuous short time window, it is determined that the bundling is qualified, a stop instruction is generated, and a short-term observation is performed to confirm that there is no rebound. It needs to be noted that the setting of the continuous short time window avoids misjudgment, and the specific length of the time window is determined by a person skilled in the art according to the actual situation. When the pressure value is greater than or equal to the preset pressure threshold and the distance value is greater than the preset distance threshold, it is determined that the bundling is abnormal, i.e., there is a potential slip or the trachea is pressed against another object. Since the collection module is located adjacent to the point where the strap is tightened, if the pressure value of the collection module is large, the distance should be that the trachea is pressed against the collection module, and it will not be greater than the preset distance threshold. At this time, a stop instruction and an alarm instruction are generated, and the alarm instruction, such as a beeping sound, reminds the user. The user can fine-tune the position of the bundling device of the embodiment to try to tighten again.

[0021] Further, the guide and binding arm 30 is open on one side, which is beneficial for the strip to be separated from the guide and binding arm 30. The guide and binding arm 30 comprises a fixed section 31 and a plurality of active sections 32 which are hingedly connected at the head and tail. The fixed section 31 is slidingly connected with the mounting portion of the handle 10, and the collecting frame 211 is rotationally connected with the fixed section 31. The guide and binding arm 30 further comprises a binding nozzle 33, a protective cover 34, a tension spring 35, a pull cable 36 and an optical shaft 37. The binding nozzle 33 is fixed to the end of the active section 32 which is farthest from the fixed section 31, which is beneficial for guiding the strip. The two ends of the tension spring 35 are respectively fixed to the ends of the adjacent protective covers 34. When the plurality of active sections 32 are bent, the tension spring 35 is also bent to store power, which provides the force required for the active sections 32 to return to the original position. The optical shaft 37 is fixed to the active section 32, which is used for guiding the pull cable 36. One end of the pull cable 36 is fixed to the fixed section 31, and the other end is sequentially fixed to the hinging points of the adjacent active sections 32 and coaxially fixed to the hinging points of the collecting frame 211 and the fixed section 31. That is, the pull cable 36 is alternately wound around the optical shaft 37 and the hinging points of the adjacent active sections 32. Referring to Figure 1 、 Figure 6 and Figure 9 When one end of the pull cable 36 is pulled, the pull cable 36 will give the active sections 32 a tightening force, so that the hinging points of the plurality of active sections 32 are bent, thereby driving the strip to be bent. In some embodiments, the way to drive the active sections 32 to bend can also be through the cooperation of a flexible rack and a gear. For example, a gear is fixed to the hinging point of the adjacent active section 32, and the flexible rack is engaged with the gear and slidingly connected with the active section 32. When one end of the flexible rack is displaced due to the overturning of the binding mechanism 20, the plurality of active sections 32 can be driven to rotate. Whether the pull cable 36 or the flexible rack is used in this embodiment is determined by the person skilled in the art according to the actual situation.

[0022] Specifically, referring to Figure 3As shown, the feeding and binding assembly 21 further comprises a feeding guide roller 212, a butt joint guide roller 213 and a guide hopper 214. The feeding guide roller 212 is provided with at least two rollers and is rotatably connected to the collecting frame 211. The butt joint guide roller 213 is provided with at least two rollers and is rotatably connected to the collecting frame 211. The guide hopper 214 is arranged below the butt joint guide roller 213 and is fixedly connected to the collecting frame 211. The two feeding guide rollers 212 are rotated towards each other to push the strip into the guide binding arm 30. The collecting frame 211 is flipped to drive the butt joint guide roller 213 to contact the end of the strip, so as to facilitate the insertion of the strip into the guide hopper 214. It is worth mentioning that the center of the guide hopper 214 and the two fastening guide rollers 222 are located on the same vertical line. The end of the collecting frame 211 is the stop position of the strip hoop. After the strip is completely fed into the guide binding arm 30, the center of the hoop at the end of the strip and the center of the guide hopper 214 are also located on the same vertical line. Thus, the guide binding arm 30 is bent and the binding mechanism 20 is flipped at the same time, so that the head of the strip is inserted into the hoop of the strip and then inserted between the two fastening guide rollers 222. The length of the guide binding arm 30 and the flipping angle of the binding mechanism 20 need to be designed by the person skilled in the art according to the specific model of the strip, which is not limited here.

[0023] Further, the driving assembly 23 comprises a first motor 231 and a gear set. The first motor 231 is fixed to the connecting frame 221. The first motor 231 drives the feeding guide roller 212 and the fastening guide roller 222 to rotate through the gear set. Specifically, the gear set comprises a first driving gear 232, a first driven gear 233, a direction-changing gear 234 and a transmission gear 235. The first driving gear 232 is fixedly connected to the output end of the first motor 231. The first driven gear 233 is fixed to the end of the fastening guide roller 222 and is engaged with the first driving gear 232. The direction-changing gear 234 is rotatably connected to the connecting frame 221. Two direction-changing gears 234 are arranged between every two first driven gears 233 and are engaged with each other. Two first driven gears 233 are respectively engaged with two direction-changing gears 234. The purpose is to Figure 3 As shown, the first motor 231 drives one of the first driven gears 233 to rotate through the first driving gear 232. The other adjacent first driven gear 233 is driven to move towards the other first driven gear 233 through the direction-changing of the two direction-changing gears 234, so as to tighten the strip. More specifically, referring to Figure 3 and Figure 4As shown, the transmission gear 235 is rotationally connected with the connecting frame 221 and is engaged with the first driving gear 232, and the outer surface of the transmission gear 235 is coaxially fixedly connected with the convex teeth 2351, and the end of one of the feeding guide rollers 212 is provided with an inner tooth groove 2121 which is in conformity with the convex teeth 2351; the purpose is that the first motor 231 drives the first driven gear 233 to rotate, and at the same time drives the convex teeth 2351 to rotate synchronously through the transmission gear 235, and the convex teeth 2351 drive the feeding guide roller 212 to rotate through the inner tooth groove 2121, so that the feeding guide roller 212 drives the rolling tape to be conveyed into the guide arm 30, and when the rolling tape is in the tightening state, the feeding guide roller 212 is separated from the rolling tape along with the collecting frame 211, the inner tooth groove 2121 and the convex teeth 2351 are also automatically disconnected, avoiding the continuous idling of the feeding guide roller 212, and increasing the force of the tightening guide roller 222 to tighten the rolling tape; it is worth mentioning that the transmission modes among the plurality of feeding guide rollers 212 are the same as those among the plurality of tightening guide rollers 222, and will not be described in detail here.

[0024] Further, referring to Figure 7 As shown, the translation and overturning mechanism 40 includes a second motor 41, a reciprocating screw rod 44, a sliding block 45, a driving gear 47, a limiting assembly 48 and a resetting assembly 49, the second motor 41 is fixed to the outer surface of the handle 10, and the output end is fixed with a second driving gear 42; both ends of the reciprocating screw rod 44 are rotationally connected with the handle 10, and both ends of the reciprocating screw rod 44 are respectively fixed with a second driven gear 43 and a transmission half tooth 46, the second driven gear 43 is engaged with the second driving gear 42; the sliding block 45 is sleeved on the reciprocating screw rod 44 and is slidingly connected with the mounting portion of the handle 10, the inside of the sliding block 45 is fixed with a crescent block, and the crescent block is slidingly connected with the reciprocating screw thread on the surface of the reciprocating screw rod 44, that is, when the reciprocating screw rod 44 rotates, the reciprocating screw thread pushes the crescent block to slide, so that the sliding block 45 slides on the mounting portion of the handle 10; Further, the drive gear 47 is engaged with the transmission half-tooth 46, and the drive gear 47 is coaxially fixedly connected with the hinge joint of the fixed section 31 and the collection frame 211, the outer surface of the fixed section 31 is fixedly connected with the connecting plate 311, the outer surface of the connecting plate 311 is provided with the through slot 312, the outer surface of the sliding block 45 is fixedly connected with the push block 451, the push block 451 penetrates through the through slot 312, the inner diameter length of the through slot 312 is greater than the thickness of the push block 451, and the purpose is to provide the push block 451 with a surplus of activity space, so that when the reciprocating lead screw 44 drives the sliding block 45 to slide away from the second motor 41, the push block 451 will not first push the connecting plate 311 to translate, so that sufficient time is provided for the transmission half-tooth 46 to drive the drive gear 47 to rotate, so that the reciprocating lead screw 44 first drives the drive gear 47 to rotate through the transmission half-tooth 46, so that the drive gear 47 drives the fastening assembly 22 to rotate to the target position through the collection frame 211, at this time, the push block 451 slides through the surplus of activity space, and the connecting plate 311 is pushed to make the guide arm 30 and the sending and binding assembly 21 translate as a whole away from the rolling strip; it should be noted that the surplus of space left by the through slot 312 for the push block 451, the specific transmission ratio of the transmission half-tooth 46 and the drive gear 47, and the number of missing teeth of the transmission half-tooth 46 need to be calculated by the person skilled in the art according to the above-mentioned action, and are not limited specifically here, that is, the sending and binding assembly 21 is turned over to make the rolling strip connected end to end after being separated from the rolling strip, and when the binding is completed, the collection frame 211 needs to be reset, the drive gear 47 is reset with the collection frame 211, the missing tooth part of the transmission half-tooth 46 contacts the drive gear 47, avoiding the direct engagement of the drive gear 47 with the transmission half-tooth 46, and avoiding the repeated work of the drive gear 47.

[0025] In order to avoid the drive gear 47 losing the engagement limit of the transmission half-tooth 46 after the sending and binding assembly 21 is translated, and the sending and binding assembly 21 is reset under the influence of the weight, the limit gear 471 is fixedly connected to the outer surface of the drive gear 47, and the limit assembly 48 is assembled on the fixed section 31, for limiting the drive gear 47 in cooperation with the limit gear 471; the reset assembly 49 is assembled on the mounting part of the handle 10, for pushing the limit assembly 48 to reset.

The wedge-shaped block 492 is hinged to the second fixed frame 491. The two ends of the second torsional spring 493 are fixedly connected to the second fixed frame 491 and the wedge-shaped block 492 respectively. When the drive gear 47 rotates with the transmission half-tooth 46, the limiting gear 471 rotates synchronously, and the limiting block 482 limits the limiting gear 471. After the drive gear 47 is disengaged from the transmission half-tooth 46, the drive gear 47 still remains limited. When the sending and binding component 21 and the guide binding arm 30 need to be reset, the sending and binding component 21 and the guide binding arm 30 move synchronously to the direction of the fastening component 22 with the limiting component 48. The wedge-shaped surface of the limiting block 482 contacts the wedge-shaped surface of the wedge-shaped block 492. Since the wedge-shaped block 492 is limited in the direction of the second fixed frame 491, the wedge-shaped block 492 pushes the limiting block 482 to rotate away from the limiting gear 471, thereby releasing the limitation of the drive gear 47. The sending and binding component 21 can be reset under the influence of gravity.

[0027] Preferably, a trachea sliding binding process is implemented based on the trachea sliding binding device described above. The binding steps include: Step one, insert the guide binding arm 30 under the trachea to be bound, and the strip passes through the binding mechanism 20 from the guide groove to the guide binding arm 30; Step two, start the translation and turnover mechanism 40 to drive the binding mechanism 20 to turn over, and drive the guide binding arm 30 to bend so that the strip is abutted at the beginning, and then the guide binding arm 30 and the sending and binding component 21 are separated from the strip; Step three, start the drive component 23 to drive the fastening component 22 to fasten the strip. The fastening component 22 drives the strip to tighten, and the collection frame 211 contacts the surface of the trachea to collect binding data. As the binding progresses, the analysis module continuously analyzes. When the pressure value reaches or exceeds the lower limit of the preset pressure threshold value, and the distance value is less than or equal to the preset distance threshold value, and the condition remains unchanged within a continuous short time window, it is determined that the binding is qualified, a stop instruction is generated, and the control module controls the drive component 23 to stop working based on the stop instruction, and a single binding is completed; Step four, slide along the trachea path to the next binding point, repeat steps one to three, and complete the trachea binding work in this way; The purpose is that the process of the embodiment cooperates with the bundling device to greatly improve the efficiency of batch bundling work, and the control of the bundling force is more accurate.

[0028] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art in the technical range disclosed by the present application can make equivalent replacement or change according to the technical trachea sliding bundling device and process of the present application and the invention concept, which should be covered in the protection scope of the present application.
