Description

Technical Field

[0001] This invention belongs to the technical field of aerated concrete processing equipment, and more specifically, it relates to an automatic wire adjustment device and adjustment method for a vertical cutting machine. Background Technology

[0002] In the production of aerated concrete blocks or panels, vertical cutting machines are key equipment used for vertically dividing the cured blanks. They achieve this by having tensioned steel wires move downwards within the blank. Currently, the core technical challenge facing the industry is that when production specifications change and the spacing or number of steel wires needs adjustment, it relies entirely on manual operation.

[0003] Specifically, operators must manually disassemble, reposition, and reinstall dozens or even hundreds of steel wires one by one from the cutting machine frame and then tension them. This method has the following drawbacks: 1. Low efficiency: The manual replacement of steel wires is cumbersome and time-consuming, leading to extended production line downtime and severely restricting production cycle and overall efficiency; 2. High labor intensity and safety risks: Operators must perform high-intensity repetitive labor at heights or in confined spaces, resulting in poor working conditions and safety hazards such as steel wire scratches; 3. Difficulty in guaranteeing cutting accuracy: The spacing and tension of manually positioned and tensioned steel wires are difficult to control precisely, easily leading to uneven cut surfaces and quality defects such as "chipped edges," affecting product qualification rates; 4. Insufficient flexibility: Frequent production changes place increasingly higher demands on the rapid response capabilities of the production line, and traditional manual methods cannot meet the needs of modern flexible and intelligent production.

[0004] Patent CN218429027U discloses an automatic wire replacement device for an autoclaved aerated concrete (AAC) billet cutting machine. The device features a wire storage assembly with several wire storage stations for storing wires to be installed. A conveying assembly sequentially transports the stored wires to the pick-and-place stations. A wire gripper assembly removes the wires from the pick-and-place stations, installs them onto the cutting machine, and removes the wires from the cutting machine, returning them to the wire storage assembly, thus achieving automatic wire feeding.

[0005] However, the above-mentioned device still has the following shortcomings in actual use: 1. The size of the limiting groove is fixed, which can only match a single specification of steel wire, resulting in a narrow range of applications. In addition, the gap between the pressure plate and the conveyor belt is fixed. For thicker or thinner steel wires, there may be problems such as "thick wire getting stuck" or "thin wires loosening and falling off", resulting in insufficient storage stability; 2. Waste steel wires rely on the release of the recycling grippers to fall freely into the recycling box. There is no guiding structure, which makes it easy for steel wires to get stuck between the grippers and the recycling box or fall outside the recycling box, resulting in a low recycling success rate; 3. The positioning and gripping accuracy is insufficient. The conveying component relies on the rotation of the conveyor belt to send the steel wire to the pick-up and put-down station. If the conveyor belt slips or the motor synchronization error occurs, the steel wire is easy to deviate from the pick-up and put-down station, and the grippers cannot grip it accurately. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic wire adjustment device and adjustment method for vertical cutting machines. Through the coordinated action of the conveying mechanism, the robot, and the storage drive mechanism, the entire process of "storage-retrieval-installation-tensioning-replacement" of the wire rope is automated without human intervention, completely freeing up manpower and solving the problems of low efficiency and high risk of traditional manual wire changing.

[0007] The aforementioned automatic wire adjustment device for vertical cutting machines includes a reciprocating conveying mechanism, a storage drive mechanism on the conveying mechanism, a wire storage turntable for storing wire rope at the output end of the storage drive mechanism, symmetrically arranged robotic arms fixedly connected to both ends of the conveying mechanism, and multiple sets of wire fixing mechanisms for installing wire rope above the conveying mechanism, with a wire tensioning mechanism for tensioning the wire rope on the wire fixing mechanism.

[0008] Preferably, it also includes a cutting machine, on which an upper support beam and a lower support beam are fixedly connected. At least one set of support mechanisms is slidably connected to the bottom of the upper support beam. Each set of support mechanisms includes at least two spaced brackets. Multiple equally spaced wire tensioning mechanisms are fixedly connected to the brackets along their length.

[0009] Preferably, the conveying mechanism includes at least two spaced sliding seats, which are slidably connected to the lower support beam. A second power mechanism is fixedly connected to the sliding seat, and a gear is fixedly connected to the output end of the second power mechanism. A rack is fixedly connected to the lower support beam, and the rack meshes with the gear and is arranged parallel to the bracket.

[0010] Preferably, the storage drive mechanism includes a power mechanism and a rotating rod. The power mechanism is fixedly connected to a sliding seat at one end, the output end of the power mechanism is connected to one end of the rotating rod, and the other end of the rotating rod is rotatably connected to the sliding seat at the other end.

[0011] Preferably, there are two wire storage turntables, which are spaced apart and coaxially fixedly connected to the rotating rod.

[0012] Preferably, the wire storage turntable includes a circular rubber plate with multiple uniformly spaced cuts along its circumference. Clamping plates are fixedly connected to both sides of the rubber plate, and cutting grooves corresponding to the cuts are spaced along their circumference.

[0013] Preferably, both the cutting groove and the entry point of the cutting slit are chamfered.

[0014] Preferably, the wire fixing mechanism includes two symmetrically arranged hanging plates, each with a hook at its bottom, the hooks facing the side of the two hanging plates that are far apart, and multiple gaps for the wire rope to pass through on the hanging plates. A limit tube is fixedly connected to one side of the two hanging plates opposite to each other, and a magnet is fixedly connected to the other side of the hanging plates. One of the hanging plates is fixedly connected to the extended end of the wire tensioning mechanism, and the wire tensioning mechanism and the other hanging plate are respectively fixedly connected to the corresponding brackets in the support mechanism.

[0015] Preferably, it further includes a wire lock sleeve for fixing the end of the wire rope. The wire lock sleeve includes a positioning sleeve and a clamping lock sleeve. A sliding rod is provided between the positioning sleeve and the clamping lock sleeve. A wire guide hole is opened in the sliding rod. One end of the sliding rod is fixedly connected to the clamping lock sleeve. The other end of the sliding rod extends into the positioning sleeve and slides with the positioning sleeve. An elastic component two is provided in the positioning sleeve that abuts against the sliding rod. A trapezoidal groove is opened in the clamping lock sleeve. A symmetrically arranged clamping block is slidably connected in the trapezoidal groove. An elastic component one is provided in the clamping lock sleeve that abuts against the end of the clamping block away from the sliding rod.

[0016] The automatic wire adjustment method for vertical cutting machines, employing the aforementioned automatic wire adjustment device, includes the following steps: S1. Insert both ends of the steel wire rope to be used into the steel wire lock sleeves respectively. Through the coordinated action of the robotic arm and the storage drive mechanism, the robotic arms at both ends grab the corresponding steel wire lock sleeves respectively, thereby placing the steel wire rope into the two steel wire storage turntables for storage. S2. Adjust the wire fixing mechanism according to the size of the block, start the conveying mechanism, drive the storage drive mechanism, wire storage turntable and robot arm to move until the robot arm reaches the corresponding hanging plate position. Then, the two symmetrical robot arms move synchronously, clamp the wire lock sleeves at both ends of the wire rope from both sides, and pull the positioning sleeves to both sides so that the wire rope passes through the corresponding gap on the hanging plate. At this time, the elastic component two is compressed, the robot arm releases the positioning sleeve, and the positioning sleeve is pressed against the corresponding hanging plate under the reset action of the elastic component two, which plays the role of pre-positioning. At the same time, the magnet will attract the wire lock sleeve to further prevent it from falling off. S3. Repeat S2, and through the coordinated action of the robotic arm and the storage drive mechanism, until all the wire ropes are installed in place on the corresponding wire fixing mechanism, start the wire tensioning mechanism to tension them. S4. When the block specifications change, the wire locking sleeve is placed in the required gap through the coordinated action of the storage drive mechanism and the robot arm, thus completing the adjustment of the cutting specifications.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves full automation of the "storage-retrieval-installation-tensioning-replacement" process of wire rope by coordinating the actions of the conveying mechanism, the robotic arm, and the storage drive mechanism. No manual intervention is required, completely freeing up manpower and solving the problems of low efficiency and high risk of traditional manual wire changing. Moreover, multiple gaps are opened on the hanging plate, which can match different cutting thickness requirements without replacing parts, adapting to the needs of large-scale continuous production, significantly shortening the wire changing and specification switching time, and adapting to the cutting needs of blocks of different specifications without the need for additional customized special equipment.

[0018] 2. A wire locking sleeve is added, which adapts to the clamping requirements of wire ropes of different diameters through elastic components. Combined with an adjustable tensioning mechanism, it further broadens the applicability of the device. The trapezoidal groove structure of the wire locking sleeve converts axial force into radial clamping force, and the anti-slip texture enhances friction. Combined with the elastic components, it dynamically compensates for the tension force, preventing the wire rope from slipping or shifting during cutting.

[0019] 3. The wire storage turntable adopts a rubber plate, and the chamfered design of the cutting groove and cutting seam makes it easy to pick up and put down the wire rope and avoids scratching the wire rope when storing it; and the two wire storage turntables rotate synchronously on the same axis to ensure that the wire rope is loaded and unloaded at the same speed and prevents tangling.

[0020] 4. When switching cutting specifications, this invention only requires the robotic arm to move the wire lock sleeve to the corresponding gap and the storage drive mechanism to adjust the position of the wire rope. No manual measurement or adjustment is required, making it simple to operate and easy to use. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example 1: like Figure 2 As shown, an automatic wire adjustment device for a vertical cutting machine includes a reciprocating conveying mechanism 27. A storage drive mechanism 26 is mounted on the conveying mechanism 27. The output end of the storage drive mechanism 26 is equipped with a wire storage turntable 25 for storing the wire rope 4. The storage drive mechanism 26 provides power to the wire storage turntable 25, driving it to rotate to achieve the storage and take-up of the wire rope 4. Two wire storage turntables 25 are used to clamp the wire rope 4 near both ends, achieving orderly storage of the wire rope 4 and preventing tangling. Symmetrically arranged mechanical parts are fixedly connected to both ends of the conveying mechanism 27. Two robotic arms 24 are responsible for gripping or releasing both ends of the wire rope 4, working in conjunction with the conveying mechanism 27 and the wire storage turntable 25 to automatically pick up, place, and install the wire rope 4, freeing up manpower. Above the conveying mechanism 27 are multiple sets of wire fixing mechanisms 23 for installing the wire rope 4. These mechanisms fix the wire rope 4 on the cutting machine 1 and adjust the cutting thickness. The wire fixing mechanisms 23 are equipped with wire tensioning mechanisms 22 for tensioning the wire rope 4. These mechanisms are preferably pneumatic cylinders and are used to adjust and maintain the tension of the wire rope 4, ensuring cutting accuracy. The conveying mechanism 27, through reciprocating movement, drives the storage drive mechanism 26, the wire storage turntable 25, and the robotic arms 24 to designated positions, achieving automatic transfer and replacement of the wire rope 4.

[0025] Example 2: like Figures 1 to 15 As shown, an automatic wire adjustment device for a vertical cutting machine further includes a cutting machine 1, preferably a frame swing cutting machine, used for cutting blocks and providing installation support for various components in this invention. An upper support beam 101 and a lower support beam 102 are fixedly connected to the cutting machine 1. At least one set of support mechanisms is slidably connected to the bottom of the upper support beam 101. The support mechanisms are slidably connected to the bottom of the upper support beam 101, and their positions can be adjusted to adapt to the cutting requirements of blocks of different specifications. The above structure is the same as the existing cutting machine structure and will not be described again. In this embodiment, two sets of support mechanisms are preferably provided, and the two sets of support mechanisms are symmetrically and staggered. This facilitates that adjacent wire fixing mechanisms 23 can also be symmetrically and staggered, so that during block cutting, the swing directions of adjacent wire fixing mechanisms 23 are opposite, avoiding the block shaking during cutting.

[0026] Specifically, each support mechanism includes at least two spaced-apart brackets 21, preferably two brackets 21, located at both ends of the wire rope 4. Multiple equally spaced wire tensioning mechanisms 22 are fixedly connected to each bracket 21 along its length. For example... Figure 2 As shown, in use, each group of wire fixing mechanisms 23 is equipped with a wire rope 4. One or both ends of the wire rope 4 can be provided with a wire tensioning mechanism 22. In this embodiment, it is preferred to provide a wire tensioning mechanism 22 at one end of the wire rope 4. In order to avoid interference, the wire tensioning mechanism 22 is provided at both ends of the adjacent wire rope 4 that are far apart.

[0027] like Figure 4 As shown, the conveying mechanism 27 includes at least two spaced sliding seats 274, which are slidably connected to the lower support beam 102. Reciprocating movement is achieved through the sliding engagement between the sliding seats 274 and the lower support beam 102. A second power mechanism 273, a servo motor, is fixedly connected to the sliding seat 274, providing driving force to the conveying mechanism 27 and driving the gear 272 to rotate. The output end of the second power mechanism 273 is fixedly connected to the gear 272. A rack 271 is fixedly connected to the lower support beam 102, meshing with the gear 272. Through this meshing transmission, the rotational motion of the second power mechanism 273 is converted into the linear motion of the sliding seat 274, thereby achieving precise movement of the conveying mechanism 27. The rack 271 is arranged parallel to the bracket 21, ensuring that the moving direction of the conveying mechanism 27 is consistent with the installation direction of the wire rope 4, ensuring precise alignment when the robot arm 24 picks up and places the wire rope 4.

[0028] The storage drive mechanism 26 includes a power mechanism 261 and a rotating rod 262. The power mechanism 261 is a servo motor that provides rotational power to the storage drive mechanism 26. The power mechanism 261 is fixedly connected to a sliding seat 274 at one end. The output end of the power mechanism 261 is connected to one end of the rotating rod 262 via a coupling. The other end of the rotating rod 262 is rotatably connected to the sliding seat 274 at the other end via a bearing and a bearing housing. When the power mechanism 261 is activated, the rotating rod 262 can transmit the torque of the power mechanism 261, driving the wire storage turntable 25 to rotate, so that the wire rope 4 to be installed is always at the top, so as to facilitate the picking and placing of the robot arm 24.

[0029] In this embodiment, there are two wire storage turntables 25, which are spaced apart and can correspond to the two ends of a wire rope 4 respectively. The wire storage turntables 25 are coaxially and fixedly connected to the rotating rod 262 to ensure that the two turntables rotate synchronously, ensuring that the wire rope 4 is wound and unwound at the same speed and avoiding tangling.

[0030] like Figures 5 to 7As shown, the wire rope storage turntable 25 includes a circular rubber plate 252. The rubber plate 252 is elastic, which can protect the surface of the wire rope 4 from wear and increase friction to prevent the wire rope 4 from slipping. Multiple cutting slits 254 are evenly opened in the circumferential direction of the rubber plate 252. The cutting slits 254 are used to embed the wire rope 4 to achieve orderly arrangement and storage of the wire rope 4. Clamping plates 251 are fixedly connected to both sides of the rubber plate 252. The clamping plates 251 can fix the rubber plate 252, enhance the structural strength of the turntable, and prevent the rubber plate 252 from deforming. Cutting grooves 253 corresponding to the cutting slits 254 are opened in the circumferential direction of the clamping plates 251. The cutting slits 254 are located in the middle of the cutting grooves 253. The cutting grooves 253 and the cutting slits 254 correspond to each other and together limit the position of the wire rope 4 to ensure the stability of the position of the wire rope 4 on the turntable.

[0031] Both the cutting groove 253 and the cutting slit 254 have chamfers 255 at their entrances. The chamfers 255 guide the wire rope 4 to smoothly enter the cutting groove 253 and the cutting slit 254, preventing the sharp edges at the entrance from scratching the wire rope 4, and reducing the resistance when the wire rope 4 enters to prevent jamming.

[0032] like Figure 2 and Figure 5 As shown, the wire fixing mechanism 23 includes two symmetrically arranged hanging plates 231. The hanging plates 231 are used to fix the wire rope 4 and cooperate with the wire tensioning mechanism 22 to automatically tension the wire rope 4. The bottom of the hanging plates 231 is provided with hooks 232, which are used to cooperate with the subsequent wire locking sleeve 3 to limit the wire locking sleeve 3 and prevent it from falling off. The hooks 232 are positioned towards the side of the two hanging plates 231 that is far apart, making it easy for the robot arm to pick up and put down the wire rope. Multiple gaps 234 are provided on the hanging plates 231 for the wire rope 4 to pass through. These multiple gaps 234 can match different cutting thickness requirements, greatly improving the versatility of the equipment, eliminating the need for manual measurement and adjustment, and resulting in high consistency of the cut blocks. A limiting tube 235 is fixedly connected to one side of the two hanging plates 231. The limiting tube 235 can press down on the wire rope 4 during cutting to radially limit its movement, preventing excessive upward deformation of the wire rope 4 and affecting the cutting quality. A magnet 233 is fixedly connected to the other side of the hanging plate 231. The magnet 233 can attract the wire lock sleeve 3, assisting in the positioning of the wire lock sleeve 3 and preventing it from falling off. During installation, one of the hanging plates 231 is fixedly connected to the extended end of the wire tensioning mechanism 22. The wire tensioning mechanism 22 and the other hanging plate 231 are respectively fixedly connected to the corresponding brackets 21 in the support mechanism. That is, one end of the hanging plate 231 extends and retracts with the wire tensioning mechanism 22, while the other end of the hanging plate 231 is fixed, realizing the tension adjustment of the wire rope 4, making it more convenient to use.

[0033] This embodiment also includes a wire lock sleeve 3 for fixing the end of the wire rope 4. The wire lock sleeve 3 is made of a metal material that can be attracted by a magnet. The wire lock sleeve 3 prevents the wire rope 4 from falling off during installation and tensioning.

[0034] like Figures 9 to 12 As shown, the wire locking sleeve 3 includes a positioning sleeve 31 and a clamping locking sleeve 33 arranged coaxially. The clamping locking sleeve 33 is used to clamp the end of the wire rope 4. After the wire rope 4 is installed, the two wire locking sleeves 3 can quickly fix the wire rope 4 to both ends of the wire storage turntable 25 or the wire fixing mechanism by compressing the positioning sleeve 31, and prevent it from falling off without manual adjustment. A sliding rod 32 is provided between the positioning sleeve 31 and the clamping lock sleeve 33. A wire guide hole 321 for the wire rope 4 to pass through is provided in the sliding rod 32. A groove 311 is provided in the positioning sleeve 31, and an annular platform 315 is fixed to the end of the positioning sleeve 31 near the sliding rod 32. One end of the sliding rod 32 is fixedly connected to the clamping lock sleeve 33, and the other end of the sliding rod 32 extends into the groove 311 in the positioning sleeve 31 and is fixed with a limiting platform 322. The limiting platform 322 cooperates with the annular platform 315 to play a mechanical limiting role and prevent the sliding rod 32 from completely coming out of the positioning sleeve 31.

[0035] The limiting platform 322 slides in conjunction with the groove 311 inside the positioning sleeve 31, which restricts the radial displacement of the sliding rod 32 and ensures smooth sliding. A sealing cover 312 is fixedly connected to the end of the positioning sleeve 31 away from the sliding rod 32. The sealing cover 312 prevents dust, impurities, etc., from entering the interior, thereby protecting components such as the second elastic component 314 and the groove 311. A wire inlet hole 313, coaxially arranged with the positioning sleeve 31, is provided on the sealing cover 312. The second elastic component 314, a spring, is located in the groove 311 inside the positioning sleeve 31, abutting against the sliding rod 32. Both ends of the second elastic component 314 abut against the sliding rod 32 and the sealing cover 312, respectively. The elastic component 314 is used to provide axial elastic buffer force, pushing the sliding rod 32 and the clamping sleeve 33 to move away from the positioning sleeve 31, thereby assisting in the tensioning of the wire rope 4; at the same time, when the positioning sleeve 31 is subjected to a pulling force towards the clamping sleeve 33, it can be pushed to fit the positioning sleeve 31 tightly in the fixed position under the reset action.

[0036] The clamping sleeve 33 has a trapezoidal groove 336 and an elastic component groove 335. The elastic component groove 335 is coaxially arranged with the clamping sleeve 33. The longitudinal section of the trapezoidal groove 336 is an isosceles trapezoid, and the midline of the diagonal of the isosceles trapezoid is collinear with the axis of the clamping sleeve 33. The upper base of the isosceles trapezoid is located on the side close to the sliding rod 32.

[0037] A trapezoidal groove 336 is slidably connected to symmetrically arranged clamping blocks 331. The trapezoidal groove 336 has inclined surfaces on both sides, which convert axial force into radial force, forcing the two clamping blocks 331 to move synchronously towards the axis. This design is suitable for steel wires of various thicknesses. The trapezoidal groove 336 has a rectangular cross-section, which limits the clamping blocks 331, ensuring they can only move along the axis of the clamping sleeve 33. During processing, anti-slip textures are provided on opposite sides of the two clamping blocks 331. These textures increase the coefficient of friction of the contact surfaces when the wire rope 4 is subjected to axial tension and vibration during cutting, preventing relative sliding between the clamping blocks 331, ensuring stable clamping position, and preventing cutting accuracy deviations. Simultaneously, they reduce the wear rate of the wire rope 4 surface and the contact surfaces of the clamping blocks 331, extending the service life of the components.

[0038] The clamping sleeve 33 has an elastic component 332 in its elastic component groove 335 that abuts against the end of the clamping block 331 away from the sliding rod 32. The elastic component 332 is a spring and provides axial thrust to the clamping block 331, driving it to slide along the inclined surface of the trapezoidal groove 336, generating radial clamping force. An end cap 333 is fixedly connected to the end of the clamping sleeve 33 away from the sliding rod 32. The end cap 333 limits the elastic component 332 to prevent it from falling off. The end cap 333 has a coaxial wire outlet hole 334, through which the wire rope 4 passes, thereby ensuring that the wire rope 4 has accurately passed between the clamping blocks 331. Other structures are the same as in Embodiment 1.

[0039] like Figure 15 As shown, an automatic wire adjustment method for a vertical cutting machine is described, employing the aforementioned automatic wire adjustment device for a vertical cutting machine. The adjustment steps are as follows: S1. Insert both ends of the steel wire rope 4 to be used into the steel wire lock sleeve 3 respectively. The installation process is as follows: One end of the wire rope 4 is inserted through the wire inlet hole 313, and then passes sequentially through the slide groove 311, the wire guide hole 321, the channel between the two clamping blocks 331 (the two clamping blocks 331 are slightly open under the initial thrust of the elastic component 332, reserving space for the wire rope 4 to enter), the elastic component groove 335, and finally exits through the wire outlet hole 334, completing the fixation of one end of the wire rope 4; the other end of the wire rope 4 is operated in the same way. At this time, after the wire rope 4 is inserted, the elastic component 332 in the wire lock sleeve 3 continuously applies axial thrust to the clamping blocks 331, pushing the two clamping blocks 331 to slide along the inclined surface of the trapezoidal groove 336. Since the longitudinal section of the trapezoidal groove 336 is an isosceles trapezoid, the axial force is converted into a radial force through the inclined plane, which forces the two clamping blocks 331 to move towards the axis synchronously. The anti-slip texture on their opposite sides is in close contact with the surface of the wire rope 4, realizing automatic clamping and fixing of the wire rope 4 and preventing loosening during initial installation.

[0040] The robotic arms 24 at both ends respectively grasp the positioning sleeves 31 of the corresponding wire lock sleeves 3, and the two robotic arms pull the positioning sleeves 31 to the side, so that the positioning sleeves 31 move towards the clamping lock sleeves 33, thereby compressing the elastic component 2 314. The two robotic arms 24 work together to make the wire rope 4 enter the corresponding cutting slots 254 of the two wire storage turntables 25. The cutting slots 254 can clamp the wire rope 4, preventing the wire rope 4 from falling off when the wire storage turntable 25 drives the wire rope 4 to the bottom. The robotic arms 24 release the positioning sleeves 31, the elastic component 2 314 resets, and pushes the positioning sleeves 31 to press tightly against the corresponding wire storage turntable 25, thereby further fixing the wire rope 4.

[0041] Start the storage drive mechanism 26, which can drive the wire storage turntable 25 to rotate. Through the coordinated action of the storage drive mechanism 26 and the wire storage turntable 25, repeat the above actions so that all the wire rope 4 is installed into the cutting slot 254 of the wire storage turntable 25.

[0042] S2. According to the size of the block, adjust the relative position of the two hanging plates 231 through the sliding support mechanism; start the second power mechanism 273, the gear 272 at its output end meshes with the rack 271, converting the rotational motion into the linear motion of the sliding seat 274, driving the entire conveying mechanism 27, storage drive mechanism 26, wire storage turntable 25 and robot 24 to move along the direction of rack 271 until the robot 24 reaches the position of the corresponding hanging plate 231.

[0043] Two symmetrical robotic arms 24 move synchronously, clamping the wire lock sleeves 3 at both ends of the wire rope 4 from both sides and pulling the positioning sleeves 31 to both sides, so that the wire rope 4 passes through the corresponding gaps 234 on the hanging plate 231. At this time, the elastic component 214 is compressed, and the robotic arms 24 release the positioning sleeves 31. Under the reset action of the elastic component 214, the positioning sleeves 31 are tightly attached to the corresponding hanging plate 231, which plays a role in pre-positioning. At the same time, the magnet 233 will attract the wire lock sleeves 3, further preventing them from falling off.

[0044] If the position of the wire rope 4 on the wire storage turntable 25 needs to be adjusted, the power mechanism 261 is started, and the rotating rod 262 is driven to rotate through the coupling, thereby driving the two coaxially fixed wire storage turntables 25 to rotate synchronously, rotating the wire rope 4 to be grabbed to the uppermost position, ensuring that the robot arm 24 can grab it vertically and avoid interference.

[0045] S3. Repeat step 2 until all wire ropes 4 are installed in place on the corresponding wire fixing mechanism 23, then start the wire tensioning mechanism 22 to tension them. Figure 13 and Figure 14As shown, during tensioning, the wire tensioning mechanism 22 contracts, causing the corresponding hanging plate 231 to push the positioning sleeve 31 towards the clamping lock sleeve 33 until the positioning sleeve 31 and the clamping lock sleeve 33 are in contact. At this time, the elastic component 314 inside the positioning sleeve 31 is compressed by the relative movement between the positioning sleeve 31 and the sliding rod 32. As the wire tensioning mechanism 22 continues to apply tension, the positioning sleeve 31 pushes the sliding rod 32 to move away from the positioning sleeve 31, thereby causing the clamping lock sleeve 33 to move synchronously.

[0046] Driven by the sliding rod 32, the clamping sleeve 33 moves away from the positioning sleeve 31. Inside, the clamping block 331, under the action of the elastic component 332, clamps the wire rope 4, gradually tightening it. Simultaneously, the wire rope 4, subjected to axial tension, tends to break free from the clamping sleeve 33 in the opposite direction. This tendency causes the clamping block 331 to make a slight displacement away from the end cap 333, which is converted into a larger radial clamping force through the inclined structure of the trapezoidal groove 336. The contact between the two clamping blocks 331 and the wire rope 4 becomes tighter, and the anti-slip texture further enhances friction, ensuring that the wire rope 4 does not slip during tensioning, thus completing the tensioning of the wire rope 4.

[0047] S4. When the block specifications change, the wire lock sleeve 3 is placed in the required gap 234 by the coordinated action of the storage drive mechanism 26 and the robot arm 24, thus completing the adjustment of the cutting specifications.

[0048] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
