Description

Technical Field

[0001] This invention relates to the field of cable cutting surface sealing technology, specifically a fully automatic cable cutting surface sealing device. Background Technology

[0002] According to material quality inspection requirements, all cable materials in storage must undergo material quality inspection and mobile rapid inspection. For cable material quality inspection, a 1-3 meter section must be cut as a test sample. Mobile rapid inspection measures the resistance of the entire cable reel, requiring the caps at both ends of the cable to be cut open. Currently, after inspection, the cable cross-section needs to be sealed to protect the exposed core and insulation layer, while also preventing environmental hazards from entering and avoiding secondary damage between inspection and resumption of use.

[0003] Existing cable cross-section sealing methods typically include two types: temporary sealing (insulating tape sealing and heat shrink tube sealing) and permanent sealing (special sealing caps (mechanical seals), epoxy resin sealing, and cold shrink tube sealing). Among the temporary sealing methods, insulating tape sealing is usually suitable for short-term (within one week) protection and its applicability is not strong. Heat shrink tube sealing, on the other hand, can meet the temporary protection needs of 1-3 months, and its protection time can meet most situations. It is usually carried out using fully automatic sealing devices. The working principle is roughly as follows: under the coordinated action of the PLC control module, image acquisition and automatic recognition module, clamping module and transmission module, the robotic gripper puts the heat shrink cap tube (a heat shrink tube with one end closed and the other open) onto the end of the cable (the end of the cable needs to be cleaned beforehand). The hot air gun is controlled to heat the outer surface of the heat shrink cap tube evenly in a spiral trajectory (after completing one circumferential motion, it moves a certain distance along the axis (about 1 / 3 to 1 / 2 of the diameter of the cap tube)), so that the heat shrink cap tube shrinks and tightly wraps around the end of the cable. On this basis, hot melt adhesive can be added to the inner wall of the heat shrink cap tube to improve the sealing effect.

[0004] The inner diameter of the heat shrink tubing is typically 1.2 to 1.5 times the cable diameter to avoid installation difficulties due to an insufficient inner diameter (especially when the cable has insulation or slight deformation), while also accommodating minor operational deviations. During the heat sealing process, the distance between the inner wall of the heat shrink tubing and the outer wall of the cable must remain constant. This ensures a uniform fit after shrinkage, preventing gaps, wrinkles, or stress concentrations, thus guaranteeing sealing and insulation effectiveness. While the heat gun heats the outer surface of the heat shrink tubing evenly in a spiral trajectory during heat shrinking, the heating surface of the heat gun is only in one direction. Even with a spiral trajectory, initially, only one side of the heat shrink tubing is heated. This can lead to a slight positional shift in the heat-shrinkable cap tube during initial heating (this is because the shrinkage of the heat-shrinkable cap tube depends on the release of elastic potential energy by the molecular chains upon heating; when heated on one side, the directly heated area (such as the left side of the tube) will reach the shrinkage temperature first, and the molecular chains will reset and undergo radial shrinkage; while the unheated / insufficiently heated area (such as the right side of the tube) remains in its original state and does not shrink significantly. This imbalance of "one side shrinking, one side not shrinking" will cause the tube to deform and move towards the heated side), making it impossible to maintain a uniform distance between the inner wall of the heat-shrinkable cap tube and the outer wall of the cable. This can lead to gaps, wrinkles, or stress concentrations in the heat-shrinkable cap tube during subsequent heating, thus affecting the sealing and insulation effect. To address this, a fully automatic cable cutting surface sealing device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic cable cutting surface sealing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic cable cutting surface sealing device, comprising: A fixed frame, wherein a movable groove is provided in the middle of the fixed frame; The sealing assembly, located above the fixed frame, is used to heat the heat shrink cap tube in a spiral trajectory manner. It includes a lifting plate, a rotating plate rotatably mounted on the upper middle part of the lifting plate, and a hot air gun fixedly mounted on the upper end of the rotating plate. A cable positioning assembly for positioning the end of a cable includes two movable plates, both of which are located inside movable slots. Positioning slots are formed at the ends of the two movable plates that are close to each other, and the two positioning slots close together to form a trumpet-shaped structure that is narrower at the top and wider at the bottom. A semi-circular arc plate is fixedly installed at the upper end of each of the two movable plates. The bottom opening of the semi-circular arc plate is aligned with the upper opening of the positioning slot, and the inner diameter of the semi-circular arc plate is equal to the outer diameter of the cable. The heat shrinkable tube positioning assembly comprises six components arranged in a circular array on the inner walls of two semi-circular plates for positioning the heat shrinkable tube. It includes a third electric telescopic rod, the telescopic end of which is fixedly connected to a lifting block. A lower U-shaped plate is fixedly connected to one side of the upper end of the lifting block, and an upper U-shaped plate is rotatably connected above the lower U-shaped plate. A fourth electric telescopic rod is positioned between the upper and lower U-shaped plates.

[0007] As a further preferred embodiment of this technical solution, a central groove is provided in the middle of the lifting plate, the diameter of which is larger than the outer diameter of the semi-circular arc plate. Side plates are fixedly connected to both ends of the lifting plate, and a first electric telescopic rod is provided below each of the two side plates. The outer shell of the first electric telescopic rod is fixedly connected to the side wall of the fixed frame through angle steel. The telescopic end of the first electric telescopic rod is fixedly connected to the bottom of the side plate. Guide holes are provided at the four corners of the lifting plate. Four guide posts are fixedly installed at the upper end of the fixed frame, and the four guide posts correspond one-to-one with the four guide holes. The guide posts and guide holes slide and fit together.

[0008] As a further preferred embodiment of this technical solution, an annular plate is fixedly connected to the bottom of the rotating plate, and an annular groove is formed on the upper surface of the lifting plate. The annular plate and the annular groove are adapted to each other. An external gear is fixedly sleeved on the outer wall of the rotating plate. A drive gear is provided on one side of the external gear. The drive gear and the external gear mesh with each other. A motor is provided below the drive gear. The motor is fixedly installed at the bottom of the lifting plate. The output shaft of the motor passes through the lifting plate and is fixedly connected to the bottom axis of the drive gear. A bearing is provided between the output shaft of the motor and the lifting plate. A protective shell is provided outside the drive gear and the external gear. The edge of the protective shell is fixedly connected to the lifting plate by screws.

[0009] As a further preferred embodiment of this technical solution, the sum of the heights of the lifting plate, the rotating plate, and the motor is less than the length of the semi-circular arc plate.

[0010] As a further preferred embodiment of this technical solution, a connecting block is fixedly sleeved on the outer wall of the hot air gun, and threaded holes are respectively opened at both ends of the connecting block. A mounting base is fixedly installed on the upper end of the rotating plate, and the upper surface of the mounting base is adapted to the lower surface of the connecting block. Fixed vertical plates are fixedly connected to both sides of the upper end of the mounting base, and through holes are opened on the fixed vertical plates. The through holes are aligned with the threaded holes, and the diameter of the through holes is equal to the diameter of the threaded holes.

[0011] As a further preferred embodiment of this technical solution, guide blocks are fixedly connected to both sides of the movable plate, and guide grooves are respectively opened on the two inner walls of the movable groove. The two guide blocks are slidably engaged with the two guide grooves respectively. A second electric telescopic rod is respectively provided on the side of the two movable plates that are far apart from each other. The housing of the second electric telescopic rod is respectively fixedly installed on the two symmetrical outer walls of the fixed frame. The telescopic end of the second electric telescopic rod slides through the fixed frame and is fixedly connected to the side wall of the movable plate. After the cable end is sealed, because the cable end is covered with heat shrink cap tube, its diameter becomes larger and cannot be withdrawn from the semi-circular arc plate. At this time, the telescopic ends of the two second electric telescopic rods are controlled by the PLC control system to retract, causing the two movable plates to move away from each other, thereby releasing the restriction of the semi-circular arc plate on the cable end. Three storage slots are opened on the inner walls of the two semi-circular arc plates, and the six storage slots are arranged in a ring array.

[0012] As a further preferred embodiment of this technical solution, the upper U-shaped plate and the lower U-shaped plate have equal thicknesses, the thickness of the upper U-shaped plate does not exceed one-tenth of the cable diameter, and one end sidewall of both the upper U-shaped plate and the lower U-shaped plate is tangent to the inner wall of the semi-circular arc plate.

Slider blocks are fixedly connected to both sides of the lifting block. Sliding grooves are opened on the two mutually symmetrical inner walls of the storage groove. The two sliders are slidably installed in the two sliding grooves respectively. The length of the upper U-shaped plate is less than the length of the lifting block.

[0014] As a further preferred embodiment of this technical solution, a first fixed post is fixedly installed on the inner wall of the lower U-shaped plate, and a lower sleeve is fixedly connected to the bottom of the fourth electric telescopic rod. The lower sleeve is fitted onto the outer wall of the first fixed post and is rotatably connected to the first fixed post. Two baffles are also fixedly installed on the outer wall of the first fixed post, located on both sides of the lower sleeve. A second fixed post is fixedly installed on the inner wall of the upper U-shaped plate, and an upper sleeve is fixedly connected to the upper end of the fourth electric telescopic rod. The upper sleeve is fitted onto the outer surface of the second fixed post and is rotatably connected to the second fixed post. The lower sleeve is fitted onto the outer wall of the second fixed post. Two additional baffles are fixedly installed on the upper sleeve. The two baffles are located on both sides of the upper sleeve. Through the cooperation of the lower sleeve and the first fixed column, and the cooperation of the upper sleeve and the second fixed column, the two ends of the fourth electric telescopic rod can be rotatably connected to the lower U-shaped plate and the upper U-shaped plate, respectively. The upper ends of the lower U-shaped plate are fixedly installed with mounting blocks on both sides, and the two ends of the mounting blocks are fixedly connected with connecting shafts. The bottom ends of the upper U-shaped plate are fixedly installed with connecting plates. The connecting plates have an inverted U-shaped structure. Rotating holes are opened on the two vertical plates of the connecting plates. The two connecting shafts are located in the two rotating holes, and the connecting shafts are rotatably engaged with the rotating holes.

[0015] As a further preferred embodiment of this technical solution, the first and second fixing columns are located on one side of the symmetrical plane of the lower U-shaped plate, and the two connecting shafts are located on the other side of the symmetrical plane of the lower U-shaped plate.

[0016] This invention provides a fully automatic cable cutting surface sealing device, which has the following advantages: This invention achieves automatic sealing of cable cross-sections through the coordinated action of a cable positioning component, a sealing component, and a heat-shrinkable cap tube positioning component. The cable positioning component positions the cable. After the cable is positioned, the sealing component controls a hot air gun to heat the outer wall of the heat-shrinkable cap tube from top to bottom in a spiral trajectory, causing the heat-shrinkable cap tube to shrink and wrap around the end of the cable. When the heat-shrinkable cap tube is heated, the six upper U-shaped plates in the heat-shrinkable cap tube positioning component open outwards, supporting the inner wall of the heat-shrinkable cap tube and positioning it to prevent initial positional displacement. The third electric telescopic rod retracts synchronously with the first electric telescopic rod, which can prevent interference between the position of the heat-shrinkable cap tube shrinking during heating and the position supported by the upper U-shaped plates.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: such as Figures 1 to 12 As shown in this embodiment, a fully automatic cable cutting surface sealing device includes a fixed frame 100. The fixed frame 100 has a movable groove 101 in the middle. The fixed frame 100 can be fixed to the frame of the overall device by means of components such as angle iron and screws.

[0020] In the optimized scheme, the sealing component 200 is located above the fixed frame 100 and is used to heat the heat shrink cap tube in a spiral trajectory. It includes a lifting plate 201, a rotating plate 205 is rotatably installed at the upper middle part of the lifting plate 201, and a hot air gun 208 is fixedly installed at the upper end of the rotating plate 205.

[0021] refer to Figure 3 , Figure 4 and Figure 6The lifting plate 201 has a central groove 203 in its middle. Side plates 204 are fixedly connected to both ends of the lifting plate 201. A first electric telescopic rod 214 is installed below each of the two side plates 204. The outer shell of the first electric telescopic rod 214 is fixedly connected to the side wall of the fixed frame 100 via angle steel. The telescopic end of the first electric telescopic rod 214 is fixedly connected to the bottom of the side plate 204. The telescopic end of the first electric telescopic rod 214 can be controlled to extend and retract via a PLC control system, causing the lifting plate 201 to move up and down. Guide holes 212 are provided at each of the four corners of the lifting plate 201. Four guide posts 213 are fixedly installed at the upper end of the fixed frame 100. The four guide posts 213 are respectively connected to four guide posts. Holes 212 correspond one-to-one, and the guide post 213 slides and engages with the guide hole 212. The guide post 213 and guide hole 212 ensure smoother up-and-down movement of the lifting plate 201. An annular plate 206 is fixedly connected to the bottom of the rotating plate 205. An annular groove 202 is formed on the upper surface of the lifting plate 201. The annular plate 206 and annular groove 202 are mutually adapted, allowing the rotating plate 205 and lifting plate 201 to rotate. An external gear 207 is fixedly sleeved on the outer wall of the rotating plate 205. A drive gear 209 is provided on one side of the external gear 207. The drive gear 209 meshes with the external gear 207. The lower... A motor 210 is provided, which is fixedly installed at the bottom of the lifting plate 201. The output shaft of the motor 210 passes through the lifting plate 201 and is fixedly connected to the bottom axis of the drive gear 209. A bearing 211 is provided between the output shaft of the motor 210 and the lifting plate 201. The output shaft of the motor 210 is controlled to rotate by a PLC control system, which drives the drive gear 209 to rotate. The drive gear 209 drives the external gear 207 to rotate, thereby driving the rotating plate 205 to rotate. A protective shell 700 is provided on the outside of the drive gear 209 and the external gear 207. The edge of the protective shell 700 is fixedly connected to the lifting plate 201 by screws. A connecting block 60 is fixedly sleeved on the outer wall of the hot air gun 208. The connecting block 600 has threaded holes 601 at both ends. A mounting base 602 is fixedly installed on the upper end of the rotating plate 205. The upper surface of the mounting base 602 is adapted to the lower surface of the connecting block 600. Fixed vertical plates 603 are fixedly connected to both sides of the upper end of the mounting base 602. A through hole 604 is provided on the fixed vertical plate 603, and the through hole 604 is aligned with the threaded hole 601. The diameter of the through hole 604 is equal to the diameter of the threaded hole 601. When installing the hot air gun 208, the connecting block 600 on the hot air gun 208 can be placed on the mounting base 602, and the position of the hot air gun 208 can be finely adjusted so that the threaded hole 601 on the connecting block 600 is aligned with the through hole 604 on the fixed vertical plate 603.Next, rotate the fixing screws and insert them into the through hole 604 and threaded hole 601 to fix the hot air gun 208 onto the annular plate 206. This installation method facilitates the installation and removal of the hot air gun 208, making its maintenance more convenient. Furthermore, removing the hot air gun 208 ensures it will not interfere with the installation of the protective housing 700.

[0022] In the optimized solution, the cable positioning assembly 300 is used to position the end of the cable. It includes two movable plates 301, both of which are located inside the movable groove 101. Each of the two movable plates 301 has a positioning groove 307 at one end that is close to each other. The two positioning grooves 307 are closed to form a trumpet-shaped structure that is narrow at the top and wide at the bottom. A semi-circular arc plate 302 is fixedly installed on the upper end of each of the two movable plates 301. The bottom opening of the semi-circular arc plate 302 is aligned with the upper opening of the positioning groove 307. The inner diameter of the semi-circular arc plate 302 is equal to the outer diameter of the cable. The axis of the two semi-circular arc plates 302 when closed coincides with the axis of the rotating plate 205.

[0023] Initial identification stage: The image acquisition and automatic identification system (e.g., including industrial cameras and vision processing software) acquires images of the cable end and heat shrink tubing, identifies the position and orientation of the cable end, and sends the coordinate information to the PLC control system.

[0024] Positioning Phase: Based on the received coordinate information, the PLC control system controls the first robotic gripper to move the cable end below the positioning groove 307 of the device (this robotic gripper needs to hold the cable until the cable cross-section sealing is completed, thus fixing the cable). The PLC control system then controls the first robotic gripper to move upward, causing the cable end to insert into the positioning groove 307. The positioning groove 307 has a trumpet-shaped structure, which ensures that the cable end can enter the positioning hole formed by the two semi-circular plates 302 along the positioning groove 307 (initially, the two semi-circular plates 302 are in a closed state). The inner diameter of the semi-circular plates 302 is equal to the outer diameter of the cable, which can achieve a converging and positioning effect on the cable end. The cable end extends out of the semi-circular plates. The length of the 302 heat shrink tubing should not exceed 10cm (the specific length depends on the length of the heat shrink tubing used, but should not exceed 10cm). If the length of the cable end extending beyond the semi-circular plate 302 is too long, the cable end is prone to natural bending, and the longer the extension, the greater the degree of bending, causing the axis of the cable end to deviate from the preset position, affecting the accurate fitting of the heat shrink tubing to the cable end. The shorter the length of the cable end extending beyond the semi-circular plate 302, the smaller the degree of bending. If the extension length is within 10cm, it can be ensured that the axis of the cable end will not deviate from the preset position (because the inner diameter of the heat shrink tubing is larger than the outer diameter of the cable, minor deviations will not have an impact), ensuring that the heat shrink tubing can be accurately fitted to the cable end.

[0025] refer to Figure 5 and Figure 7 Guide blocks 304 are fixedly connected to both sides of the movable plate 301. Guide grooves 102 are respectively opened on the two inner walls of the movable groove 101. The two guide blocks 304 are slidably engaged with the two guide grooves 102 respectively. A second electric telescopic rod 303 is respectively provided on the side of the two movable plates 301 that is far apart from each other. The housing of the second electric telescopic rod 303 is respectively fixedly installed on the two mutually symmetrical outer walls of the fixed frame 100. The telescopic end of the second electric telescopic rod 303 slides through the fixed frame 100. 0 and fixedly connected to the side wall of the movable plate 301. After the cable end is sealed, the cable end is covered with a heat-shrinkable cap tube, and its diameter becomes larger, making it impossible to exit from the semi-circular plate 302. At this time, the telescopic ends of the two second electric telescopic rods 303 are controlled by the PLC control system to retract, causing the two movable plates 301 to move away from each other, thereby releasing the restriction of the semi-circular plate 302 on the cable end. Three storage slots 305 are opened on the inner walls of the two semi-circular plates 302, and the six storage slots 305 are arranged in a ring array.

[0026] The diameter of the central groove 203 is larger than the outer diameter of the semi-circular plate 302. This arrangement ensures that the lifting plate 201 will not interfere with the semi-circular plate 302 when it moves up and down.

[0027] In the optimized scheme, the heat shrinkable cap tube positioning assembly 400 consists of six components arranged in a ring array on the inner walls of two semi-circular plates 302. These components are used to position the heat shrinkable cap tube and prevent it from moving when it shrinks due to heat, thus preventing the tube's axis from deviating from the cable's axis. The system also includes a third electric telescopic rod 401, with a lifting block 403 fixedly connected to its telescopic end. A lower U-shaped plate 405 is fixedly connected to one side of the upper end of the lifting block 403. An upper U-shaped plate 406 is rotatably connected above the lower U-shaped plate 405. A fourth electric telescopic rod 407 is positioned between the upper and lower U-shaped plates 406 and 405, with its upper and lower ends rotatably connected to the upper and lower U-shaped plates 406 and 405, respectively.

[0028] Heating and sealing stage: After the cable is positioned, the PLC control system controls the second robotic gripper to grasp the heat shrink cap and place it onto the cable end. At this time, the PLC control system starts the hot air gun 208 and the motor 210, and controls the extension end of the first electric telescopic rod 214 to retract. This drives the hot air gun 208 to heat the outer wall of the heat shrink cap from top to bottom in a spiral trajectory, so that the heat shrink cap seals the cable end. Hot melt adhesive can also be applied to the inner wall of the heat shrink cap. After the hot melt adhesive melts when heated, it can fill the tiny gaps between the heat shrink cap and the cable. The gaps allow for better sealing. Before heating, the PLC control system also controls the telescopic ends of the six fourth electric telescopic rods 407 to retract to a suitable length, causing the six upper U-shaped plates 406 to open outwards. The upper U-shaped plates 406 support the inner wall of the heat shrink cap tube and position it. Initially, the top of the lower U-shaped plate 405 is located in the middle area of ​​the heat shrink cap tube (the height of the lower U-shaped plate 405 can be adjusted by the third electric telescopic rod 401). During heating, when the heat shrink cap tube shifts position due to heat, the six opened upper U-shaped plates 406... 6 can block the heat shrink tubing, ensuring it remains centered on the cable. The initial heating point of the hot air gun 208 is typically the upper edge of the heat shrink tubing, while the upper U-shaped plate 406 initially supports the middle section of the tubing. This ensures that the initial heat shrinkage of the tubing does not interfere with the support of the upper U-shaped plate 406. Subsequently, the PLC control system controls the third electric telescopic rod 401 to retract at the same speed as the first electric telescopic rod 214, ensuring the upper U-shaped plate... The position supported by 406 will move downward synchronously with the position of the heat shrink cap tube as it shrinks due to heat, so as to avoid interference between the position of the heat shrink cap tube as it shrinks due to heat and the position supported by the upper U-shaped plate 406 during the heating process. The movement of the third electric telescopic rod 401 will stop when the upper U-shaped plate 406 enters the storage slot 305 along with the lifting block 403. At this time, since the upper half of the heat shrink cap tube has been shrunk and attached to the outer wall of the cable, the heat shrink cap tube itself is in a fixed state and there is no need to worry about it moving. Therefore, the upper U-shaped plate 406 does not need to position it at this time. Completion and unloading stage: After heating, the PLC control system shuts down the hot air gun 208 and the motor 210, and controls the extension end of the first electric telescopic rod 214 to extend, so that the lifting plate 201 returns to the initial position. Since the end of the cable is covered with a heat shrink cap, its diameter increases and it cannot exit from the semi-circular plate 302. At this time, the PLC control system controls the extension ends of the two second electric telescopic rods 303 to retract, driving the two movable plates 301 to move away from each other, releasing the restriction of the semi-circular plate 302 on the end of the cable. At this time, the first mechanical gripper can drive the end of the cable to move downward and place the cable at the collection point. After the cable is removed, the extension end of the fourth electric telescopic rod 407 is controlled to extend, so that the upper U-shaped plate 406 returns to the vertical state. At the same time, the extension end of the third electric telescopic rod 401 is controlled to extend, controlling the lower U-shaped plate 405 to return to the initial height.

[0029] The upper U-shaped plate 406 and the lower U-shaped plate 405 have the same thickness. The thickness of the upper U-shaped plate 406 does not exceed one-tenth of the cable diameter. One end sidewall of both the upper U-shaped plate 406 and the lower U-shaped plate 405 is tangent to the inner wall of the semi-circular plate 302.

[0030] Since the inner diameter of the heat shrink cap is usually 1.2 to 1.5 times the cable diameter, as long as the thickness of the upper U-shaped plate 406 does not exceed one-tenth of the cable diameter, and one end of the upper U-shaped plate 406 can be tangent to the outer wall of the cable, it can be ensured that the upper U-shaped plate 406 will not interfere with the end of the heat shrink cap sleeve fitted onto the cable.

[0031] Among them, reference Figure 10 , Figure 11 as well as Figure 12The third electric telescopic rod 401 has T-shaped plates 402 fixedly connected to both sides of its housing. The other T-shaped plate 402 is fixedly connected to the inner wall of the storage groove 305. Slider blocks 404 are fixedly connected to both sides of the lifting block 403. Sliding grooves 306 are respectively opened on the two symmetrical inner walls of the storage groove 305. The two sliders 404 are slidably installed in the two sliding grooves 306. A fixing post 408 is fixedly installed on the inner wall of the lower U-shaped plate 405. The bottom of the fourth electric telescopic rod 407 is fixedly connected to a lower sleeve 410, which is sleeved on the outer wall of the first fixed post 408. The lower sleeve 410 is rotatably connected to the first fixed post 408. Two baffles are also fixedly installed on the outer wall of the first fixed post 408, located on both sides of the lower sleeve 410. A second fixed post 409 is fixedly installed on the inner wall of the upper U-shaped plate 406. The upper end of the fourth electric telescopic rod 407 is fixedly connected to an upper sleeve 411. The upper sleeve 411 is fitted onto the outer surface of the second fixed post 409. The upper sleeve 411 is rotatably connected to the second fixed post 409. Two other baffles are fixedly installed on the outer wall of the second fixed post 409. The other two baffles are located on both sides of the upper sleeve 411. Through the cooperation of the lower sleeve 410 and the first fixed post 408, and the cooperation of the upper sleeve 411 and the second fixed post 409, the two ends of the fourth electric telescopic rod 407 can rotate with the lower U-shaped plate 405 and the upper U-shaped plate 406, respectively. The lower U-shaped plate 405 has mounting blocks 500 fixedly installed on both sides of its upper end. The mounting blocks 500 are fixedly connected to connecting shafts 501 at both ends. The upper U-shaped plate 406 has connecting plates 502 fixedly installed at both ends of its bottom. The connecting plates 502 have an inverted U-shaped structure. Rotating holes 503 are provided on both vertical plates of the connecting plates 502. The two connecting shafts 501 are located in the two rotating holes 503 respectively. The connecting shafts 501 are rotatably engaged with the rotating holes 503.

[0032] Among them, the first fixing post 408 and the second fixing post 409 are located on one side of the symmetrical plane of the lower U-shaped plate 405, and the two connecting shafts 501 are located on the other side of the symmetrical plane of the lower U-shaped plate 405.

[0033] This configuration ensures that the axis of the fourth electric telescopic rod 407 is offset from the axis of the connecting shaft 501. Consequently, it ensures that the force generated by the extension and retraction of the fourth electric telescopic rod 407 is offset from the rotation center between the lower U-shaped plate 405 and the upper U-shaped plate 406, so that the upper U-shaped plate 406 will only rotate in one direction (i.e., deviate from the direction). This ensures that when the six fourth electric telescopic rods 407 retract, the six upper U-shaped plates 406 will only open outward and not retract inward.

[0034] The length of the upper U-shaped plate 406 is less than the length of the lifting block 403.

[0035] With this configuration, even if the upper U-shaped plate 406 is rotated to a horizontal position, the upper U-shaped plate 406 can retract into the storage slot 305 along with the lifting block 403, thus avoiding interference between the upper U-shaped plate 406 and the storage slot 305.

[0036] The sum of the heights of the lifting plate 201, the rotating plate 205, and the motor 210 is less than the length of the semi-circular plate 302. This arrangement ensures that the hot air gun 208 can heat the upper end of the semi-circular plate 302.

[0037] It should be noted that in the technical solution of this invention, the relevant components (such as the semi-circular plate 302, the lower U-shaped plate 405, and the upper U-shaped plate 406) are all designed to be quick-changeable, and can be adapted to different specifications of cables by replacing the module groups of different sizes.

[0038] The wiring diagrams for the hot air gun 208, motor 210, first electric telescopic rod 214, second electric telescopic rod 303, third electric telescopic rod 401, fourth electric telescopic rod 407, PLC control system, and image acquisition and automatic recognition system in this invention are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring layouts of the hot air gun 208, motor 210, first electric telescopic rod 214, second electric telescopic rod 303, third electric telescopic rod 401, fourth electric telescopic rod 407, PLC control system, and image acquisition and automatic recognition system will not be explained in detail.
