Description

Technical Field

[0001] This application relates to the field of water quality measurement equipment technology, and in particular to a cable start / stop detection device and an automatic cable laying device. Background Technology

[0002] With the development of water quality testing technology, online automatic water quality monitoring technology has emerged. The main forms of online automatic water quality monitoring are applying for monitoring land and constructing fixed and permanent automatic monitoring stations. The goal of the construction is to promptly grasp the water quality status of key sections of major river basins, provide early warning and forecast of major or basin-wide water pollution accidents, resolve water pollution accident disputes across administrative regions, and supervise the implementation of the total quantity control system.

[0003] In related technologies, buoy-type automatic water quality monitoring systems can automatically and continuously monitor water quality, transmit data remotely automatically, and query data from designated stations at any time. The winch control cable-laying device has led to its widespread application in this monitoring field. However, the aforementioned cable-laying device, which uses permanent magnets embedded in the cable in conjunction with a magnetic induction sensor, sends a signal to the controller when the sensor detects the permanent magnets, thus starting and stopping the winch. This method requires pre-embedding magnets in the cable, and the magnets are easily damaged by compression or the cable core during winding, resulting in low reliability. Summary of the Invention

[0004] Therefore, it is necessary to address the issue of low reliability in current winch cable start-stop methods by providing a cable start-stop detection device and an automatic cable routing device, which can improve the reliability of cable start-stop and thus improve the wiring quality of the automatic cable routing device.

[0005] The technical solution is as follows: A cable start / stop detection device, comprising: a mounting component for connection with a cable laying mechanism, the mounting component having a first through hole for cable passage; a detection assembly including a buffer, a trigger, a first detection element, and a sensor, the trigger being connected to the mounting component via the buffer, the buffer applying a reset force to the trigger away from the mounting component, the trigger having a second through hole corresponding to the first through hole for cable passage, the first detection element being connected to the mounting component, the sensor being connected to the trigger, the trigger being able to move closer to or further away from the mounting component, causing the sensor to engage with the first detection element, the first detection element being electrically connected to the cable laying mechanism; and a locking block for connection to the cable, the locking block engaging with the wall of the second through hole during cable rewinding and unwinding to drive the trigger element to move.

[0006] The aforementioned cable start / stop detection device, during installation, connects the mounting component to the cable laying mechanism. The cable passes sequentially through the first and second through holes in the cable laying mechanism, and a locking block is fixed to the cable. During operation, the cable moves upward through the second through hole for wiring. When the locking block reaches the wall of the second through hole, since the second through hole cannot allow the locking block to pass through, the locking block pulls upward, causing the trigger element to move upward. This triggers the sensor element, indicating that the cable has reached the start / stop limit point. The first detector element then triggers a start / stop signal and transmits it to the cable laying mechanism, which stops operating, and the cable is retracted. This cable start / stop detection device eliminates the need to add magnetic elements to the cable after breaking it, requiring no special requirements for the cable, which helps ensure the cable's lifespan. Furthermore, by adjusting the position of the locking block on the cable, it is convenient to set the cable length that needs to be limited for start / stop, which helps improve the reliability of cable start / stop and thus improves the wiring quality of the automatic cable laying equipment.

[0007] In one embodiment, the cable start / stop detection device further includes a guide seat, the first detection element is connected to the mounting element through the guide seat, the guide seat is provided with a guide portion, and the sensing element is guided and cooperated with the guide portion.

[0008] In one embodiment, the first detection element is a photoelectric sensor, the sensing element is a blocking plate, the blocking plate and the photoelectric sensor cooperate to generate a first detection signal, and the cable laying mechanism can receive the first detection signal and perform a first action.

[0009] In one embodiment, the detection component further includes a second detection element, the first detection element and the second detection element are spaced apart along the height direction of the mounting element, the sensing element is inductively coupled with both the first detection element and the second detection element, the sensing element and the second detection element inductively coupled to generate a second detection signal, and the cable laying mechanism is able to receive the second detection signal and perform a second action.

[0010] In one embodiment, the detection component further includes a follower element, which is movably connected to the trigger element. The trigger element has a follower hole with a diameter larger than that of the cable. A second through hole is disposed on the follower element, and the follower element is capable of moving within the follower hole.

[0011] In one embodiment, the follower includes a first follower plate and a second follower plate, which are respectively disposed on opposite sides of the trigger. The first follower plate and / or the second follower plate are provided with a connecting portion. The first follower plate is connected to the connecting portion through the second follower plate, and the connecting portion is located in the follower hole.

[0012] An automatic cable laying device is provided, comprising a cable laying mechanism and a cable start / stop detection device as described in any one of the above. The cable laying mechanism includes a driving component and a cable laying component, the cable laying component being drivenly connected to the driving component, the driving component driving the cable laying component to reciprocate along the length direction of the driving component, and a mounting component being connected to the cable laying component.

[0013] In the aforementioned automatic cable laying device, during installation, the mounting components are connected to the cable laying mechanism. The cable passes sequentially through the first and second through holes, and a locking block is fixed to the cable. During operation, the cable moves upward through the second through hole. When the locking block reaches the wall of the second through hole, the hole prevents the block from passing through. Therefore, the upward movement of the locking block causes the trigger element to move upward, allowing the sensor to be detected by the first detection element. This indicates that the cable has reached the start / stop limit point. The first detection element triggers a start / stop signal and transmits it to the cable laying mechanism, which then stops operating, completing the cable retrieval. This cable start / stop detection device eliminates the need for adding magnetic elements to the cable after breaking it, requiring no special cable specifications, thus ensuring cable lifespan. Furthermore, by adjusting the position of the locking block on the cable, the required cable length for start / stop can be easily set, improving the reliability of cable start / stop and ultimately enhancing the wiring quality of the automatic cable laying device.

[0014] In one embodiment, the driving component includes a first support base, a second support base, a slide rail, a bidirectional screw, and a driven wheel. The slide rail and the bidirectional screw are both connected between the first support base and the second support base. The cable routing component is provided with a first slider, which is threadedly engaged with the bidirectional screw. The cable routing component is sleeved on the slide rail and slides with the slide rail.

[0015] In one embodiment, the cable routing component includes a first mounting plate, a second mounting plate, a first guide wheel, and a second guide wheel. The first mounting plate and the second mounting plate are spaced apart. The first slider is disposed between the first mounting plate and the second mounting plate. The first guide wheel and the second guide wheel are rotatably connected to the first mounting plate and / or the second mounting plate. The first guide wheel and the second guide wheel form a cable channel for the cable to pass through. The cable channel is correspondingly disposed to the first through hole.

[0017] In one embodiment, the automatic cable laying device further includes a first guide component, which is disposed at the end of the cable laying member away from the mounting member. The first guide component is provided with a first guide roller, which is used to guide and cooperate with the cable. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 , Figure 1 A schematic diagram showing the installation position of the cable start / stop detection device 100 according to one embodiment of this application is shown. Figure 2 A schematic diagram of the structure of the automatic cable laying device 20 described in one embodiment is shown.

[0033] Figure 3 It shows Figure 1A schematic diagram of the cable start / stop detection device 100 from another perspective. An embodiment of this application provides a cable start / stop detection device 100, which includes: a mounting member 110, a detection component 120, and a locking block 130. The mounting member 110 is used to connect with a cable routing mechanism 200, and has a first through hole 111 for cable passage. The detection component 120 includes a buffer member 121, a trigger member 122, a first detection member 123, and a sensing member 124. The trigger member 122 is connected to the mounting member 110 through the buffer member 121, and the buffer member 121 applies a reset force to the trigger member 122 in a direction away from the mounting member 110. The trigger member 122 has a second through hole 125 corresponding to the first through hole 111, for cable passage. The first detection element 123 is connected to the mounting element 110, and the sensing element 124 is connected to the trigger element 122. The trigger element 122 can move closer to or further away from the mounting element 110, causing the sensing element 124 to engage with the first detection element 123. The first detection element 123 is used for electrical connection with the cable routing mechanism 200. The locking block 130 is used to connect to the cable. When the cable is retracted or extended, the locking block 130 abuts against the wall of the second through hole 125, driving the trigger element 122 to move.

[0034] During installation, the cable start / stop detection device 100 connects the mounting component 110 to the cable laying mechanism 200. The cable passes sequentially through the first through hole 111 and the second through hole 125 from the cable laying mechanism 200, and the locking block 130 is fixed to the cable. During operation, the cable moves upward from the second through hole 125 for wiring. When the locking block 130 moves to the wall of the second through hole 125, since the second through hole 125 cannot allow the locking block 130 to pass through, the locking block 130 pulls upward, causing the trigger component 122 to move upward. This allows the sensing component 124 to be detected by the first detection component 123, indicating that the cable has reached the start / stop limit point. The first detection component 123 can trigger a start / stop signal and transmit it to the cable laying mechanism 200, causing the cable laying mechanism 200 to stop operating and the cable recovery to be completed. This cable start / stop detection device 100 eliminates the need to add magnetic elements to broken cables, requiring no special requirements for the cables, which helps ensure the service life of the cables. Furthermore, by adjusting the position of the clips 130 on the cable, it is convenient to set the cable length that needs to be limited to start / stop, which helps to improve the reliability of cable start / stop and thus improve the wiring quality of the automatic cable laying equipment 20.

[0035] It should be noted that the ability of the trigger 122 to move closer to or further away from the mounting member 110, allowing the sensing member 124 to engage with the first detection member 123, should be understood as follows: under the action of an external force, the trigger 122 can compress the buffer 121, causing the buffer 121 to deform and move towards the mounting member 110. This causes the sensing member 124 to engage with the first detection member 123, resulting in the first detection member 123 generating a sensing signal. After the external force disappears, the trigger 122 returns to its initial position under the restoring force provided by the buffer 121.

[0036] It should also be noted that when the cable is being wound up or down, the contact between the locking block 130 and the wall of the second through hole 125, which drives the trigger 122 to move, should be understood as the diameter of the second through hole 125 being smaller than the outer diameter of the locking block 130, so that the buckle cannot pass through the second through hole 125. Therefore, when the cable pulls the locking block 130 up, the locking block 130 contacts the trigger 122, which can drive the trigger 122 to move upward.

[0037] Optionally, the buffer 121 can be a spring, an airbag, foam cushioning material, or other cushioning structure.

[0038] Specifically, please refer to Figure 1 The buffer 121 includes a return spring and a guide rod. The return spring is sleeved on the guide rod, and the trigger 122 is movably connected to the mounting part 110 through the guide rod. Therefore, the spring can play a role in buffering and resetting through elastic deformation, and the guide rod can guide and support the movement of the trigger 122.

[0039] In one embodiment, see Figure 1 and Figure 2 The cable start / stop detection device 100 also includes a guide seat 140, through which the first detection element 123 is connected to the mounting element 110. The guide seat 140 has a guide portion 141, and the sensing element 124 is guided and engaged with the guide portion 141. Thus, when the sensing element 124 moves upward following the trigger element 122, i.e., moves closer to the mounting element 110, the guiding effect of the guide portion 141 stabilizes the movement trajectory of the sensing element 124, thereby improving the reliability of the sensing engagement between the sensing element 124 and the first detection element 123.

[0040] Optionally, the guide portion 141 can be a guide groove, guide hole, guide post, guide rail or other guide structure.

[0041] Specifically, please refer to Figure 1 and Figure 2The guide portion 141 is a rectangular groove, and the sensing element 124 is a rectangular baffle structure. Therefore, the sensing element 124 can slide within the guide portion 141, which helps to ensure the movement stability of the sensing element 124 and avoids loosening or tilting of the sensing element 124, which could lead to disengagement from the first detection element 123. This embodiment only provides a specific structural form of the guide portion 141, but is not limited thereto.

[0042] The sensing element 124 and the first detection element 123 can be in a contact manner or a non-contact manner.

[0043] Optionally, the first detection element 123 can be a photoelectric sensor, ultrasonic sensor, capacitive sensor, inductive sensor, laser sensor, proximity switch, magnetic switch or other sensor types.

[0044] Specifically, please refer to Figure 1 The first detection element 123 is a photoelectric sensor, and the sensing element 124 is a blocking plate. The blocking plate and the photoelectric sensor work together to generate a first detection signal. The cable arrangement mechanism 200 can receive the first detection signal and perform a first action. For example, the first action is to reduce the rotational speed of the cable arrangement mechanism 200 or to stop the cable arrangement mechanism 200. Therefore, when the start / stop limit point reaches the position of the trigger element 122, the locking block 130 drives the trigger element 122 to move upward, which in turn drives the sensing element 124 to move and be detected by the first detection element 123. After the first detection element 123 generates the first detection signal, it can control the cable arrangement mechanism 200 to perform the corresponding first action, thereby realizing automatic start / stop detection, which has high reliability and helps to improve the service life of the cable arrangement mechanism 200.

[0045] In one embodiment, see Figure 1 The detection component 120 also includes a second detection element 126, with the first detection element 123 and the second detection element 126 spaced apart along the height direction of the mounting component 110. The sensing element 124 engages with both the first detection element 123 and the second detection element 126, generating a second detection signal. The cable routing mechanism 200 can receive this second detection signal and perform a second action. Specifically, both the first detection element 123 and the second detection element 126 are mounted on the guide seat 140. Optionally, the first and second actions can be the same or different actions. For example, the first detection element 123 is located below the second detection element 126. The sensing element 124 first senses the first detection element 123, and the first action is for the cable routing mechanism 200 to reduce its rotation speed. After the second detection element 126 senses the sensing element 124, the cable routing mechanism 200 stops.

[0046] In other embodiments, the first action and the second action may both be to stop the cable laying mechanism 200, thereby forming dual sensing and further improving the detection accuracy.

[0047] In order to further understand and explain the height direction of the mounting component 110, Figure 1 For example, the height direction of mounting component 110 is... Figure 1 The direction pointed to by any arrow on the straight line S1.

[0048] Furthermore, the cable start / stop detection device 100 can also intercept and remove entangled objects on the cable: when an entangled object is attached to the cable, since the follower 127 is only suitable for the wire diameter to pass through, under the obstruction of the entangled object, the follower 127 is pulled up, causing the trigger 122 to move upward, and the buffer 121 is compressed, causing the photoelectric baffle to block the first detection element 123. If the entangled object is relatively loose, it can be removed by the reset reaction force of the buffer 121, thus achieving automatic removal. If the entanglement is tight, the buffer 121 will be further compressed, and the sensor 124 will continue to block the second detection element 126, indicating that the entangled object is difficult to remove. When the controller receives the first detection signal and the second detection signal, it will stop the cable unwinding mechanism 200 and trigger an alarm.

[0049] In other embodiments, based on the obstruction feedback signal, in order to enable the device to automatically remove tangled objects and enhance the robustness of the device, thereby reducing the workload of manual troubleshooting, the program control can be improved by adding a function to diagnose and self-repair faults. When an obstruction is encountered, a section of cable is lowered and then pulled up again, and this process is repeated multiple times to remove the tangled objects. If the objects cannot be removed, the machine should be stopped to prevent the tangled objects from being drawn into the cable unwinding mechanism 200.

[0050] In one embodiment, see Figure 1 and Figure 3 The detection component 120 also includes a follower 127, which is movably connected to the trigger 122. The trigger 122 has a follower hole 128, the diameter of which is larger than the diameter of the cable. A second through hole 125 is provided on the follower 127, allowing the follower 127 to move within the follower hole 128. Therefore, during cable arrangement and winding, the cable will swing, and the follower hole 128 provides a buffer zone for the cable's swing and offset, allowing the follower 127 to swing within the follower hole 128 with the cable's swing. This increases the offset range caused by the swinging angle of the cable, helping to prevent the trigger 122, fixed at the bottom, from being crushed or damaged by the force of the cable's swing.

[0051] In one embodiment, see Figure 1 and Figure 3The follower 127 includes a first follower plate 1271 and a second follower plate 1272. The first follower plate 1271 and the second follower plate 1272 are respectively disposed on opposite sides of the trigger 122. The first follower plate 1271 and / or the second follower plate 1272 are provided with a connecting portion. The first follower plate 1271 is connected to the connecting portion through the second follower plate 1272, and the connecting portion is located in the follower hole 128. Specifically, the lengths of both the first follower plate 1271 and the second follower plate 1272 are greater than the diameter of the follower hole 128. For example, the first follower plate 1271 and the second follower plate 1272 are cross-connected to form a "+" shaped follower structure, thus preventing the follower plate from detaching from the follower hole 128 and allowing it to move at any position within the follower hole 128, increasing the swing range of the cable, reducing friction, and engaging with the second follower plate 1272 to drive the trigger plate upward.

[0052] The fact that the first follower plate 1271 and / or the second follower plate 1272 are provided with connecting parts should be understood as follows: the connecting parts can be provided on the first follower plate 1271, or on the second follower plate 1272, or there can be two connecting parts, with both the first follower plate 1271 and the second follower plate 1272 being provided with connecting parts, and the two connecting parts being connected in the follower hole 128.

[0053] In one embodiment, see Figure 2 This application also includes an automatic cable laying device 20, which includes a cable laying mechanism 200 and a cable start / stop detection device 100 of any of the above. The cable laying mechanism 200 includes a driving member 210 and a cable laying member 220. The cable laying member 220 is drivenly connected to the driving member 210. The driving member 210 drives the cable laying member 220 to reciprocate along the length direction of the driving member 210. The mounting member 110 is connected to the cable laying member 220.

[0054] In the aforementioned automatic cable laying device 20, during installation, the mounting component 110 is connected to the cable laying mechanism 200. The cable passes sequentially through the first through hole 111 and the second through hole 125 from the cable laying mechanism 200, and the locking block 130 is fixed to the cable. During operation, the cable moves upward from the second through hole 125 for wiring. When the locking block 130 moves to the wall of the second through hole 125, since the second through hole 125 cannot allow the locking block 130 to pass through, the locking block 130 pulls upward, causing the trigger component 122 to move upward. This causes the sensing component 124 to be detected by the first detection component 123, indicating that the cable has reached the start / stop limit point. The first detection component 123 can trigger a start / stop signal and transmit it to the cable laying mechanism 200, causing the cable laying mechanism 200 to stop operating and the cable recovery to be completed. This cable start / stop detection device 100 eliminates the need to add magnetic elements to broken cables, requiring no special requirements for the cables, which helps ensure the service life of the cables. Furthermore, by adjusting the position of the clips 130 on the cable, it is convenient to set the cable length that needs to be limited to start / stop, which helps to improve the reliability of cable start / stop and thus improve the wiring quality of the automatic cable laying equipment 20.

[0055] To further understand and explain the length direction of the drive component 210, Figure 2 For example, the length direction of the driving component 210 is... Figure 2 The direction pointed to by any arrow on the straight line S2.

[0056] It should be noted that the cable laying component 220 and the driving component 210 are connected in a way that can be either a direct connection or an indirect connection through an intermediate connecting mechanism. The driving component 210 serves as a power source and can drive the cable laying component 220 to reciprocate.

[0057] The driving component 210 can be a motor, cylinder, hydraulic cylinder or other driving form, or it can be a transmission component that receives power from other driving mechanisms to achieve movement.

[0058] In one embodiment, see Figure 2The driving component 210 includes a first support base 211, a second support base 212, a slide rail 213, a bidirectional screw 214, and a driven wheel 215. The slide rail 213 and the bidirectional screw 214 are both connected between the first support base 211 and the second support base 212. The cable laying component 220 is provided with a first slider 221, which is threadedly engaged with the bidirectional screw 214. The cable laying component 220 is sleeved on the slide rail 213 and slidably engaged with it. Thus, the driven wheel 215 is driven by the winch motor driving the drum to rotate, thereby driving the bidirectional screw 214 to rotate. The bidirectional screw 214 and the cable laying component 220 form a transmission pair, enabling the cable laying component 220 to drive the cable start / stop detection device 100 to reciprocate axially along the bidirectional screw 214. The slide rail 213 guides and positions the cable laying component 220, resulting in a stable structure and high reliability.

[0059] The length direction of the driving component 210 is the axial direction of the bidirectional screw 214.

[0060] During the cable laying process, when the winch control motor drives the drum to rotate, the driving wheel on the drum transmits power to the driven wheel 215 via a chain. The driven wheel 215 drives the bidirectional screw 214 to rotate, causing the first slider 221 to reciprocate linearly along the axis of the bidirectional screw 214. The cable on the cable laying member 220 is wound into the drum. When the cable moves one wire diameter along the axis of the bidirectional screw 214, the cable is wound around the drum once. When the cable is fully wound and reaches the edge of the drum, the cable laying member 220 also transitions to the opposite direction at the end of the thread, driving the cable to move back and forth and enter a new layer of winding, thus achieving a multi-layered and neat arrangement of the cable on the drum.

[0061] Specifically, please refer to Figure 2 The first support 211 is provided with a first bearing seat 2111, and the second support 212 is provided with a second bearing seat 2121. The bidirectional screw 214 is rotatably connected to the first bearing seat 2111 and the second bearing seat 2121 respectively. In this way, the smooth rotation of the bidirectional screw 214 can be guaranteed.

[0062] Please see Figure 1 and Figure 4 , Figure 4A schematic diagram of the cable routing mechanism 200 according to one embodiment of this application is shown. In one embodiment, the cable routing component 220 includes a first mounting plate 223, a second mounting plate 224, a first guide wheel 225, and a second guide wheel 226. The first mounting plate 223 and the second mounting plate 224 are spaced apart, and a first slider 221 is disposed between the first mounting plate 223 and the second mounting plate 224. The first guide wheel 225 and the second guide wheel 226 are rotatably connected to the first mounting plate 223 and / or the second mounting plate 224. The first guide wheel 225 and the second guide wheel 226 form a cable channel for the cable to pass through, and the cable channel is correspondingly disposed with the first through hole 111. Therefore, the first mounting plate 223 and the second mounting plate 224 play a fixing role for the first guide wheel, the second guide wheel, and the mounting component 110. When the cable is pulled up or down, the first guide wheel 225 and the second guide wheel 226 can guide the movement of the cable, making the movement of the cable smoother, reducing friction, and improving the service life of the cable.

[0063] Further, please refer to Figure 4 The cable routing component 220 also includes a second slider 222, which is connected between the first mounting plate 223 and the second mounting plate 224, and the second slider 222 is guided and engaged with the slide rail 213. Therefore, it is beneficial to further improve the smoothness of the movement of the cable routing component 220, reduce friction and noise, and improve durability.

[0064] In one embodiment, see Figure 1 and Figure 4 There are at least two first guide wheels 225 and at least two second guide wheels 226. At least two first guide wheels 225 are spaced apart along the height direction of the cable routing member 220, and at least two second guide wheels 226 are spaced apart along the height direction of the cable routing member 220. This allows for the formation of a longer cable channel, thereby reducing cable sway and improving the stability of the cabling.

[0065] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The automatic cable laying device 20 also includes a first guide assembly 230, which is located at the end of the cable laying member 220 away from the mounting member 110. The first guide assembly 230 is provided with first guide rollers 231, which are used to guide the cable. Specifically, there are at least two first guide rollers 231, which are spaced apart to form a first guide channel, which is connected to the cable channel. Therefore, the guiding effect of the cable can be further improved, the cable sway can be reduced, and the cable can be neatly wound into the drum under the guidance of the first guide assembly 230.

[0066] Further, please refer to Figure 4The automatic cable laying device 20 also includes a second guide assembly 240, which is disposed at the end of the cable laying member 220 near the mounting member 110. The second guide assembly 240 is provided with second guide rollers 241, which are used to guide the cable. Specifically, there are at least two second guide rollers 241, which are spaced apart to form a second guide channel, which is connected to the cable channel. Therefore, it can provide guidance at both the inlet and outlet ends of the cable laying member 220, reduce cable sway, and allow the cable to stably enter the cable channel under the guidance of the second guide assembly and exit from the first guide assembly 230.
