Description

Technical Field

[0001] This invention belongs to the field of cable installation technology, and in particular relates to a cable handling device specifically designed for computer cabinets. Background Technology

[0002] When computer cabinets are installed and deployed on site, the cable laying path and wiring length need to be determined according to the actual layout. Prefabricated cables cannot be used in advance. Therefore, the ends of general cables need to be stripped on site to ensure reliable connection of equipment terminals and meet the cabling installation requirements of the computer room.

[0003] Current cable stripping equipment typically uses specialized stripping blades to circumferentially cut the cables to strip their insulation, such as the cable processing equipment for computer cabinets disclosed in patent publication number CN110445063B. However, the diameters of cables installed on-site in the cabinets vary, requiring pre-adjustment of the blade position for different diameter cables, which is cumbersome. At the same time, the stripping process requires a high degree of cable straightness. If the cable is placed crookedly or not sufficiently straight, it can easily lead to deviations in the circumferential cutting position and uncontrolled cutting depth, which can not only damage the wire core but also fail to adapt to the changing construction conditions on-site, affecting the efficiency of on-site construction and the reliability of wiring. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a cable handling device specifically designed for computer cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable handling device specifically for computer cabinets, comprising a base and a controller fixed to the surface of the base, and further comprising: Both side plates are fixed to the upper surface of the base, and both side plates have coaxial cable through holes on their side walls. The side walls of the two side plates facing each other are integrally formed with symmetrical limiting baffles. A flexible cutting wire is disposed between the two limiting baffles. The flexible cutting wire is wound in a teardrop shape. A driving unit is installed on the side plate, and the driving unit tensions and moves both ends of the flexible cutting wire. The clamping unit is located on the outside of the two side plates.

[0006] Preferably, the drive unit includes two symmetrically arranged linear drive guide mechanisms. The linear drive guide mechanisms are fixed to the side wall of the side plate. The moving end of the linear drive guide mechanism is fixed with a horizontal slide groove. A sliding block is slidably connected inside the horizontal slide groove. The end of the flexible cutting wire is detachably connected to the sliding block. The side wall of the side plate has two symmetrical arc-shaped guide holes. The side wall of the sliding block is rotatably connected with a guide rod, and the guide rod rolls along the arc-shaped guide hole. The linear drive guide mechanism is electrically connected to the controller.

[0007] Preferably, the clamping unit includes two sets of clamping seats, and the two sets of clamping seats are respectively arranged on opposite sides of two side plates. The number of clamping seats in the same set is two, and several dovetail clamping plates are fixed on the side walls of the two clamping seats facing each other in the same set. The dovetail clamping plates on the two clamping seats in the same set are staggered. A hand drive mechanism is provided on the inner side of the two side plates, and the hand drive mechanism drives the two sets of clamping seats to move horizontally in opposite directions.

[0008] Preferably, the hand-driven mechanism includes a fixed plate fixed to the lower side between two side plates. The side wall of the fixed plate has a strip-shaped hole, and connecting blocks are slidably connected to both sides of the inside of the strip-shaped hole. A bidirectional screw is rotatably connected inside the strip-shaped hole, and both connecting blocks are threadedly connected to the bidirectional screw. The side walls of the two side plates have translation holes corresponding to the positions of the strip-shaped holes, and two translation blocks are slidably connected inside the translation holes. The translation blocks are fixedly connected to the connecting blocks on the same side. A fixed post is fixed to the side wall of one set of clamping seats, and a telescopic component is fixedly inserted into the side wall of the other set of clamping seats. The fixed post and the telescopic component are both fixedly connected to the side wall of the corresponding translation block.

[0009] Preferably, the telescopic component is an elastic telescopic component, and a connecting column is fixed between two telescopic components.

[0010] Preferably, each of the two cable through holes has an electric heating ring fixed to its wall, and both electric heating rings are electrically connected to the controller.

[0011] Preferably, the telescopic component is an electromagnetic push rod, and a torque sensor is fixed to the end of one of the linear drive guide mechanisms. The controller controls the telescopic component to work based on the electrical signal fed back by the torque sensor.

[0012] Preferably, a pressure sensor is provided above one of the telescopic components, and the pressure sensor is fixed to the side wall of the side plate on the same side. The pressure measuring end of the pressure sensor abuts against the side wall of the clamping seat on the same side. The controller controls the two linear drive guide rail mechanisms to work according to the electrical signal fed back by the pressure sensor.

[0013] Compared to existing technologies, the advantages of a dedicated cable management device for computer cabinets are: 1. Through the coordinated operation of the base, controller, side plate, cable through hole, limit baffle, flexible cutting wire, and drive unit, the flexible cutting wire can perform a wrap-around circumferential cutting operation on the cable insulation layer. This not only reduces the overall weight of the equipment and facilitates cable installation in computer cabinets, but also eliminates the need for blade adjustment for cables of different diameters. It can adaptively wrap and cut insulation layers of different specifications, avoiding the tedious operation of frequent blade adjustments. At the same time, it has no strict requirements on cable straightness, and can operate stably in complex cabling conditions in the cabinet, avoiding uneven cutting depth or core damage caused by cable skew, thus improving wire stripping quality and construction efficiency.

[0014] 2. The clamping unit can easily fix the cable, and the internal hand-drive mechanism can automatically peel off the cut insulation, effectively improving the ease of use of the entire device.

[0015] 3. By using an electromagnetic push rod as a telescopic component and in conjunction with a torque sensor, the peeling force on the insulation at the cable end can be automatically adjusted according to the cutting tension of the flexible cutting wire. This avoids excessive tension on the cable end initially, which could lead to overstretching of the internal core. In addition, the pressure sensor can stop the tensioning of the flexible cutting wire in time after the insulation is separated, further reducing the possibility of damage to the internal core.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1, referring to Figures 1-6 As shown, a computer cabinet cable handling device includes a base 1 and a controller 2 fixed to the surface of the base 1. It also includes two side plates 3, both of which are fixed to the upper surface of the base 1. The side walls of both side plates 3 are provided with coaxial cable through holes. The side walls of the two side plates 3 facing each other are integrally formed with symmetrical limiting baffles 4. The gap between the two limiting baffles 4 is 0.4mm. Self-locking casters (not shown in the figure) can be installed at the bottom of the base 1 to facilitate the movement of the entire device. The side walls of the side plates 3 are provided with hollow holes to reduce the overall weight.

[0020] The flexible cutting wire 5 is positioned between two limiting baffles 4. The flexible cutting wire 5 is wound in a teardrop shape. A drive unit 6 is installed on the side plate 3, and the drive unit 6 tensions and moves both ends of the flexible cutting wire 5. The drive unit 6 includes two symmetrically arranged linear drive guide mechanisms 61, which are fixed to the side wall of the side plate 3. A horizontal slide groove 62 is fixed to the moving end of each linear drive guide mechanism 61. A sliding block 63 is slidably connected inside the horizontal slide groove 62. The end of the flexible cutting wire 5 is detachably connected to the sliding block 63. The side wall of the slide block 63 has two symmetrical arc-shaped guide holes 64. The side wall of the slide block 63 is rotatably connected to a guide rod 65, and the guide rod 65 rolls along the arc-shaped guide holes 64. The linear drive guide rail mechanism 61 is electrically connected to the controller 2. The flexible cutting wire 5 is made of super-elastic nickel-titanium alloy wire with a tensile strength of 1000MPa-1500MPa and a breaking elongation of ≥20%. The diameter of the flexible cutting wire 5 is 0.3mm. The flexible cutting wire 5 and the slide block 63 are connected by components such as washers, nuts, and screws, which facilitates the replacement of the flexible cutting wire 5.

[0021] The clamping unit 7 is located on the outer side of the two side plates 3. The clamping unit 7 includes two sets of clamping seats 71, which are respectively located on opposite sides of the two side plates 3. There are two clamping seats 71 in the same set, and several dovetail clamping plates 72 are fixed on the side walls of the two clamping seats 71 facing each other. The dovetail clamping plates 72 on the two clamping seats 71 in the same set are staggered. The inner side of the two side plates 3 is provided with a hand drive mechanism 8, which drives the two sets of clamping seats 71 to move horizontally in opposite directions. The hand drive mechanism 8 includes a fixing plate 81 fixed on the lower side between the two side plates 3. The side wall of the fixing plate 81 has a strip-shaped hole, and the two sides of the inside of the strip-shaped hole are slidably connected to connecting blocks 82. The inside of the strip-shaped hole is rotatably connected to a bidirectional screw 83, and the two connecting blocks 82 are rotatably connected to the inside of the strip-shaped hole. Block 82 is threadedly connected to the bidirectional screw 83. The side walls of the two side plates 3 are provided with translation holes 84 corresponding to the positions of the strip holes. Two translation blocks 85 are slidably connected inside the translation holes 84. The translation blocks 85 are fixedly connected to the connecting blocks 82 on the same side. One set of clamping seats 71 has a fixed post 86 fixedly attached to its side wall, and the other set of clamping seats 71 has a telescopic component 87 fixedly inserted into its side wall. The fixed post 86 and the telescopic component 87 are both fixedly connected to the side wall of the corresponding translation block 85. The bidirectional screw 83 has two threaded sections with opposite thread directions. When the bidirectional screw 83 is rotated, the two connecting blocks 82 can move towards each other or in opposite directions. A handwheel is installed at the end of the bidirectional screw 83 to facilitate the rotation of the bidirectional screw 83 by the operator.

[0022] The telescopic component 87 is an elastic telescopic component. A connecting post 9 is fixed between the two telescopic components 87. Through the connecting post 9, the two telescopic components 87 can be moved simultaneously, improving the ease of use.

[0023] Both cable through holes are fixed with electric heating rings 10, and both electric heating rings 10 are electrically connected to the controller 2. The heating temperature of the electric heating rings 10 can be set by the controller 2.

[0024] The operating principle of the present invention is explained as follows: Connect the controller 2 to the external power supply line, then insert the end of the cable to be stripped into the cable through hole side of the side plate 3, and place the stripped end of the cable on the side of the telescopic component 87. Then, push the two telescopic components 87 (the telescopic component 87 is an elastic telescopic rod, which includes a cylinder, spring, movable rod and other components) towards the side plate 3 through the connecting column 9. At the same time, rotate the bidirectional screw 83. The bidirectional screw 83 can drive the two connecting blocks 82 to move towards each other. At this time, the connecting blocks 82 will drive the two clamping seats 71 in the same group to move towards each other through the translation block 85, the fixing column 86 and the telescopic component 87. Then, the dovetail clamping plate 72 on the side wall of the clamping seat 71 will abut against the cable insulation layer, thereby clamping and fixing the cable. At this time, stop rotating the bidirectional screw 83 and start the controller 2. Controller 2 immediately controls the operation of the electric heating ring 10. The heating temperature of the electric heating ring 10 can be preset by controller 2 according to the cable insulation material (controller 2 has preset softening heating temperatures corresponding to some common cable insulation materials, such as 55-65℃ for PVC insulation and 60-68℃ for PE insulation). The electric heating ring 10 heats the part of the cable to be cut through thermal radiation. The heat softens the cable insulation, facilitating the rapid cutting of the flexible wire 5. Under the effect of thermal expansion, the friction between the insulation layer at the cable end and the internal wire core is reduced, making it easier to quickly peel off the cut insulation layer. At the same time, controller 2 controls two linear drive rails. Mechanism 61 operates (linear drive guide mechanism 61 includes components such as ball screw, screw nut, motor, and bearing). Linear drive guide mechanism 61 drives horizontal slide 62 to move downward, and horizontal slide 62 drives sliding block 63 to move downward. With the cooperation of guide rod 65 and arc-shaped guide hole 64, during the downward movement of sliding block 63, it will move synchronously along horizontal slide 62 in a direction away from the cable. At this time, both ends of flexible cutting wire 5 move downward synchronously with sliding block 63 and slide in a direction away from the cable. Since the flexible cutting wire 5 is initially wound in a teardrop shape, the movement of flexible cutting wire 5 at this time can make flexible cutting wire 5 gradually tighten and wrap around the outside of the cable. With the tightening effect of flexible cutting wire 5, flexible cutting wire 5 will cut the insulation layer of the cable. Initially, because the telescopic component 87 is pre-compressed and clamps the cable, the insulation at the cable end is always subjected to the rebound pull of the telescopic component 87. Therefore, after the flexible cutting wire 5 cuts the cable insulation layer, the insulation layer at the cable end will be detached under the clamping action of the dovetail clamping plate 72 and the rebound pull of the telescopic component 87, thus completing the automatic stripping of the insulation layer at the cable end. Then, press the reset button of the controller 2, and the controller 2 will control the linear drive guide rail mechanism 61 to drive the horizontal slide 62 and the sliding block 63 to reset. Then, rotate the bidirectional screw 83 in the opposite direction to disengage the dovetail clamping plate 72 from the cable, and then take out the cable, thus completing the stripping process at the cable end.

[0025] Example 2, refer to Figures 7-8 As shown, the difference between this embodiment and embodiment 1 is that the telescopic component 87 is an electromagnetic push rod, and a torque sensor 11 is fixed at the end of one of the linear drive guide rail mechanisms 61. The controller 2 controls the telescopic component 87 to work according to the electrical signal fed back by the torque sensor 11.

[0026] A pressure sensor 12 is provided above one of the telescopic components 87, and the pressure sensor 12 is fixed to the side wall of the side plate 3 on the same side. The pressure measuring end of the pressure sensor 12 abuts against the side wall of the clamping seat 71 on the same side. The controller 2 controls the two linear drive guide rail mechanisms 61 to work according to the electrical signal fed back by the pressure sensor 12.

[0027] In this embodiment, by using an electromagnetic push rod as the telescopic component 87, when the bidirectional screw 83 is rotated to clamp and fix the cable, there is no need to pre-compress the telescopic component 87, simplifying the operation steps. Furthermore, when the controller 2 controls the linear drive guide mechanism 61 to work, the torque sensor 11 monitors the torque of the linear drive guide mechanism 61 in real time. As the flexible cutting wire 5 is tensioned and its circumferential cutting action on the cable increases, the tension on the flexible cutting wire 5 gradually increases. At this time, the resistance to the linear drive guide mechanism 61 driving the horizontal slide 62 to move increases, therefore the torque increases synchronously with the increase in cutting resistance. The torque sensor 11... Once the torque reaches the threshold (which is preset based on the cable diameter and insulation material), an electrical signal is immediately sent to the controller 2. At this time, the controller 2 immediately controls the telescopic component 87 to work. The telescopic component 87 will drive the clamping seat 71 on the same side to move away from the side plate 3, thereby applying tension to the insulation layer at the end of the cable, and then peeling off the cut insulation layer. With this design, in the initial stage of cable cutting, the telescopic component 87 will not apply outward tension to the end of the cable. Therefore, the internal core of the cable does not need to continuously bear the tension of the telescopic component 87, thus avoiding excessive stretching of the internal core of the cable and improving the stripping quality. Secondly, after the telescopic component 87 pushes the clamping seat 71 outward, the clamping seat 71 separates from the pressure sensor 12. At this time, the pressure detected by the pressure sensor 12 becomes zero, and the pressure sensor 12 will immediately send an electrical signal back to the controller 2. The controller 2 will then control the linear drive guide mechanism 61 to stop working, so as to avoid excessive tension of the flexible cutting wire 5 and damage to the wire core, thereby further improving the wire stripping quality.
