Description
Technical Field
[0001] This invention relates to the field of cable sampling technology, and more particularly to a fully automatic cable sampling device. Background Technology
[0002] In cable production inspection, engineering acceptance, and quality testing, cable sampling is a crucial step in obtaining test samples to verify product performance. This is especially true for large-section, armored cables, where the standardization of the sampling process directly affects the accuracy of the test results. Existing fully automated cable sampling devices typically include a frame box, a cutting blade assembly, a clamping and feeding mechanism, and a control system. The clamping and feeding mechanism primarily transports the cable to a preset sampling length, typically 100mm-1000mm. The left clamping structure and the upper pressing structure secure the entire cable end. Then, the cutting assembly is activated to cut the cable, completing the sampling operation.
[0003] The aforementioned existing technology suffers from the following drawbacks: during cutting, the cutting force of the cutting component is transmitted along the cable axis to the sampling end. However, the existing sampling end is in a free cantilever state, which is prone to deformation under the influence of the force. The conductors of large cables are mostly multi-stranded copper / aluminum structures. Cutting will cause the conductor wires at the sampling end to be squeezed and spread out to one side of the cut, causing the conductor cross-section to change from a circle to an ellipse or other irregular shape, affecting the accuracy of the detection of electrical performance parameters such as conductor resistance and cross-sectional area. At the same time, the insulation layer is torn. The cable insulation layer will experience stress concentration due to the shaking and pulling of the sampling end, resulting in tearing, interlayer separation, or even peeling of the insulation layer from the conductor at the cut edge, which will damage the integrity of the sample structure.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0040] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0041] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0042] Reference Figures 1-2As shown, the present invention provides a fully automatic cable sampling device, including a support assembly 2 for cable support and feeding and a support frame 201 for balanced support of the cable tail end; the support assembly 2 includes an equipment box 213, which contains a cutting assembly 5 for cutting and sampling one end of the cable, and a pressing assembly 4 for pressing the cable from above at the upper end of the cutting assembly 5; the equipment box 213 also contains a clamping unit 8 for fixing and clamping the cable sampling end, and a clamping assembly 6 for fixing the cable during cutting; the clamping unit 8 includes two sets of clamping plates 841 that can move closer or further apart from each other, and the clamping unit 8 is equipped with a collecting assembly 9 that moves closer to the two sets of clamping plates 841 to collect chips, and a transfer assembly 1 that moves further apart from the two sets of clamping plates 841 to guide the discharge of the cable sampling end.
[0043] Reference Figures 3-4 As shown, in this invention, the support component 2 is used to support, position, and feed the cable, providing a material conveying basis for subsequent cutting and sampling; as a preferred embodiment, the support component 2 includes a U-shaped support frame 21, and a moving unit is mounted on the inner bottom surface of the support frame 21. The moving unit drives the clamping unit to move linearly along the length direction of the support frame 21 to realize the feeding and cutting of the cable.
[0044] The clamping unit includes a horizontally arranged support panel 25. Two sets of bearing seats 29 are fixed near both ends of the support panel 25. A first bidirectional lead screw 210 is installed through the two sets of bearing seats 29. Two sets of symmetrically distributed sliding seats (not shown in the figure) are threaded onto the first bidirectional lead screw 210. Each set of sliding seats 2 has a clamping plate 26 fixed on its top for clamping the cable. Guide rails 27 are fixed parallel to each other on the support panel 25 on both sides of the first bidirectional lead screw 210. Two sets of sliders 28 are slidably connected to the two sets of guide rails 27. The top of the sliders 28 is fixedly connected to the bottom surface of the corresponding sliding seat 2 to guide and limit the movement of the sliding seat 2.
[0045] One end of the first bidirectional lead screw 210 is connected to a gear motor 212 via a belt drive unit 211. The belt drive unit 211 consists of a belt and a pulley and is located on one side of the bottom surface of the support panel 25. The gear motor 212 is fixed to the bottom surface of the support panel 25 and is used to drive the first bidirectional lead screw 210 to rotate, thereby driving the two sets of clamping plates 26 to move closer or further away synchronously.
[0046] The moving unit includes two sets of spaced bearing seats 24 fixed to the inner bottom surface of the support frame 21. A lead screw 241 is assembled between the two sets of bearing seats 24. A sliding seat (not shown) is threaded onto the lead screw 241. The top of the sliding seat is fixedly connected to the bottom surface of the support panel 25. The bottom surface of the sliding seat slides in cooperation with two sets of parallel guide rails 23. The guide rails 23 are fixed to the inner bottom surface of the support frame 21. One end of the lead screw 241 is connected to a drive motor (not shown) via a coupling. The drive motor is installed on the inner bottom surface of the support frame 21 and is used to drive the lead screw 241 to rotate, thereby driving the entire clamping unit to move linearly along the length of the guide rails 23 to realize the feeding of the cable.
[0047] Reference Figure 6 , Figures 8-9 As shown, in this invention, the cutting component 5 is used to cut and sample the cable after it has been fed into position. Preferably, the cutting component 5 is integrated into the upper area inside the equipment housing 213, and includes a cutting unit whose lifting action is driven by the lifting unit 56.
[0048] The cutting unit includes a frame box 51 installed at an angle inside the equipment box 213. Inside the frame box 51, two sets of spaced transmission wheels 52 are installed through bearings. A band saw 53 is wound between the two sets of transmission wheels 52. The cutting direction of the band saw 53 is perpendicular to the cable placed horizontally on the clamping unit to ensure the flatness of the cut surface. A reduction motor 54 is fixed on the outside of the frame box 51. The output end of the reduction motor 54 is coaxially fixedly connected to one of the sets of transmission wheels 52 to drive the transmission wheels 52 to rotate, thereby driving the band saw 53 to continuously rotate to achieve the cutting action.
[0049] The structure of the lifting unit 56 is similar to that of the moving unit mechanism. It is vertically arranged on the internal frame of the equipment box 213. The sliding seat of the lifting unit 56 is defined as sliding seat three 59. The outer side of the sliding seat three 59 is fixed with a support frame 510. The frame box 51 is fixed on the support frame 510. By driving the sliding seat three 59 to move up and down through the lifting unit 56, the entire cutting unit can be driven to move up and down synchronously, so as to realize the vertical cutting feed of the band saw 53 on the cable.
[0050] Reference Figure 3 and Figure 5 As shown, the clamping component 4 in this invention is used to clamp and fix the cable from above during the cable cutting process to prevent the cable from warping or shifting due to the force of the band saw 53 during cutting. Preferably, the clamping component 4 is assembled in the top area inside the equipment box 213. It includes a mounting bracket 41 fixed to the top of the inner wall of the equipment box 213. A linear electric cylinder 42 is vertically arranged on the mounting bracket 41. The output end of the linear electric cylinder 42 faces downward and is fixed with a clamping end 43.
[0051] Once the cable is fed to the cutting station and positioned by the clamping assembly 6, the linear electric cylinder 42 drives the pressing end 43 to move downward, so that it contacts the upper end face of the cable and applies a preset pressure, thereby stably pressing the cable onto the support structure below, providing a reliable positioning basis for the subsequent cutting action of the band saw 53.
[0052] Reference Figures 6-10 As shown, the clamping component 6 in this invention is used to assist in positioning and fixing the cable during the cable cutting process, so as to prevent the cable from shifting during cutting. Preferably, the clamping component 6 includes a support body 61 fixed to the bottom surface inside the equipment box 213. Horizontally arranged support rollers 62 are rotatably mounted on the support body 61 near both sides via bearings. The two sets of support rollers 62 are distributed along the cable feeding direction to support the cable and ensure its horizontal posture during transport. Two sets of vertically arranged guide rollers 63 are provided on both sides of one set of support rollers 62 on the support body 61. The two sets of guide rollers 63 form a channel adapted to the cable diameter, which plays a lateral limiting role for the cable during feeding and prevents it from shifting to the left or right.
[0053] A clamping unit 2 64 is assembled on the support body 61 in the area between the two sets of support rollers 62. The clamping unit 2 64 is used to clamp and fix the cable during the cutting action to enhance the stability of the cutting process. The structure of the clamping unit 2 64 is similar to that of the clamping unit 1. Its corresponding clamping plate 1 26 is defined as clamping plate 2 641, which is used to directly contact and clamp the cable. The corresponding belt drive unit 1 211 is defined as belt drive unit 2 65, which is used to drive the clamping plate 2 641 of the clamping unit 2 64 to realize the opening and closing action.
[0054] Reference Figures 9-13 As shown, in this invention, clamping unit 8 is used to clamp the sampling end when the cable cutting is completed, and guide the sampling end to be fed, so as to realize the collection and transportation of the sampling end. As a preferred support body 61, a roller conveyor 7 is connected to one side. One end of the roller conveyor 7 extends through and out of the outside of the equipment box 213, and is used to transport the sampling end to the outside of the equipment. A collection box 71 is provided on the side frame of the roller conveyor 7 and below the corresponding cable cutting position.
[0055] The clamping unit 8 is mounted on the side frame of the roller conveyor 7 and close to the clamping assembly 6. It includes a mounting base plate 81 fixed on the side frame of the conveyor. Two sets of guide rails 82 are fixed in parallel on the mounting base plate 81. The two sets of guide rails 82 are slidably connected to two sets of symmetrically arranged concave frames 84 through sliders 83. A clamping plate 841 is fixed on the inner side of the concave frame 84 for directly contacting and clamping the cable sampling end.
[0056] Two sets of bearing seats 85 are fixed near the sides of the mounting base 81. A third bidirectional lead screw (not shown) is installed between the two sets of bearing seats 85. The bottom surfaces of the two sets of concave frames 84 are provided with lead screw nuts (not shown) that are threaded into the third bidirectional lead screw. One end of the third bidirectional lead screw is fixed with a pulley 812. The pulley 812 is linked to the pulley 2 fixed on the output end of the belt drive unit 65 through the belt body. With the driving force output by the belt drive unit 65, the third bidirectional lead screw can be driven to rotate. Then, through the transmission action of the lead screw nut, the two sets of concave frames 84 are driven to move towards each other or separate in opposite directions along the guide rail 82, thereby completing the clamping and releasing action of the cable sampling end.
[0057] Reference Figures 12-17 As shown, in this invention, the transfer component 1 is used to connect the clamping unit 3 8 and the roller conveyor 7 to achieve smooth guidance of the cable sampling end and at the same time protect the transmission components of the clamping unit 3 8. Preferably, the transfer component 1 is assembled in the upper area of the two sets of bearing seats 3 85. It includes a support member 11 vertically fixed on the two sets of bearing seats 3 85, and a support shaft 12 is movably passed between the two sets of support members 11. The two ends of the support shaft 12 are provided with anti-detachment parts, and a torsion spring 13 is connected between the anti-detachment parts and the side of the support member 11. A guide plate 14 is fixedly sleeved on the support shaft 12. Under the pre-tightening force of the torsion spring 13, the guide plate 14 is initially inclined towards the roller conveyor 7.
[0058] The side of the guide plate 14 is nested with telescopic plate 142 and telescopic plate 143. The inclination angle of the two is the same as that of the guide plate 14. When the two sets of concave frames 84 approach each other to clamp the cable, the telescopic plate 142 and telescopic plate 143 will retract and fit together as the concave frames 84 move. The guide plate 14 spans the internal space of the two sets of concave frames 84. It can shield and protect the third bidirectional lead screw to prevent chips from entering the transmission area. It can also receive the sampling end after sampling and guide it to the roller conveyor 7 below.
[0059] To accommodate large cables of different diameters and ensure that the guide plate 14 remains horizontal during clamping to stably support the sampling end, a set of bearing housings 85 is equipped with a linkage unit that moves with the two sets of concave frames 84 to keep the guide plate 14 horizontal and shield the third bidirectional lead screw. The linkage unit includes a protective cover 114 fixed to the bearing housing 85. A bearing shaft 15 is mounted on the base plate 116 of the protective cover 114 via bearings. A bevel gear 3 is fixed on the bearing shaft 15, and the bevel gear 3 meshes with... A bevel gear 121 is fixed to the anti-detachment part of the support shaft 12; a first gear 16 is also fixed on the bearing shaft 15, the first gear 16 meshes with a rack 19, the rack 19 is movably sleeved in the sliding sleeve 17 through the mounting sleeve 18, the sliding sleeve 17 is fixed to the bottom surface of the inner wall of the concave frame 84, a tension spring 181 is connected between the mounting sleeve 18 and one end of the inner wall of the sliding sleeve 17, and a slide rod 115 fixed to the bottom surface of the mounting sleeve 18 is adapted to slide in the long groove opened on the base plate 116;
[0060] In actual operation, when the two sets of concave frames 84 move towards each other, the sliding sleeve 17, under the action of transmission, pulls the mounting sleeve 18 to generate displacement by means of the elastic tension of the tension spring 181; at this time, the rack 19 fixed to the mounting sleeve 18 moves synchronously and forms a meshing transmission with the first gear 16. The power is transmitted step by step through the meshing pair of bevel gear 3 and bevel gear 2 121, and finally drives the guide plate 14 to complete the attitude conversion from the inclined state to the horizontal state.
[0061] Given that this application focuses on the adaptation requirements of large-diameter cables, the mounting sleeve 18 can always slide along the slide bar 115 to the limit end of the long slot, thereby expanding the clamping space and meeting the clamping requirements of large-diameter cables. When the two sets of concave frames 84 approach each other to a preset distance due to the difference in the diameter of the cables to be clamped, the elastic tension of the tension spring 181 can flexibly offset and buffer the opposing displacement force of the concave frames 84, ensuring that the rack 19 and the first gear 16 are always in a stable meshing state, and keeping the guide plate 14 in a horizontal position, effectively avoiding the problem of the guide plate 14 tilting and not being horizontal due to the deviation in cable diameter.
[0062] Reference Figure 12 and Figures 14-17 As shown, the collecting component 9 in this invention is mainly used to absorb and collect the generated chips during the cable cutting process, so as to prevent the chips from scattering inside the equipment and affecting the operation of the transmission components. Preferably, the collecting component 9 is assembled above the mounting base plate 81 and below the guide plate 14. It includes a pipe clamp 91 fixed on the mounting base plate 81, and a support pipe 92 is horizontally fixed on the pipe clamp 91. The two ends of the support pipe 92 are respectively movably embedded into the upper surface of two sets of concave frames 84. The support pipe 92 remains stationary as the concave frames 84 move relative to each other.
[0063] The support tube 92 is evenly connected to multiple sets of air nozzles 93 along its own axis. Each air nozzle 93 is connected to the suction hood 141 fixed on the guide plate 14 via a hose. The suction hood 141 is embedded in the surface of the guide plate 14 and can be directly aimed at the chips in the cutting area.
[0064] Inside the support tube 92, a movable tube 94 is installed via a bearing. The movable tube 94 has multiple sets of open arc grooves distributed at 90° along the axial direction (not shown in the figure). The positions of the open arc grooves correspond to the air nozzles 93. One end of the movable tube 94 extends to the outside of the support tube 92 and connects to an external negative pressure device. In the initial state, the open arc grooves of the movable tube 94 are misaligned with the air nozzles 93 of the support tube 92, and the negative pressure channel is closed at this time.
[0065] To achieve automated linkage control for chip collection, a transmission unit is provided on the side of the protective cover 114. This transmission unit synchronously drives the movable tube 94 to rotate as the concave frame 84 moves. The transmission unit includes a bevel gear 95 fixed to one end of the movable tube 94, which meshes with a bevel gear 4. A drive shaft 110 is fixed at the center of the bevel gear 4. The drive shaft 110 is mounted on the side of the protective cover 114 via bearings. A second gear 111 is fixed on the drive shaft 110, which meshes with a rack 113. The rack 113 is fixed to a set of concave frames 84 via a mounting sleeve 112.
[0066] In actual use, when the two sets of concave frames 84 are driven by the third bidirectional screw to approach and clamp the cable sampling end, the concave frame 84 connected to the rack 2 113 synchronously drives the rack 2 113 to move horizontally. The rack 2 113 meshes with the second gear 111, driving the transmission shaft 110 and the bevel gear 4 to rotate. Then, through the meshing of the bevel gear 4 and the bevel gear 1 95, the movable tube 94 is driven to rotate inside the support tube 92.
[0067] When the concave frame 84 clamps the cable in place, the open arc groove on the movable tube 94 is aligned with the air nozzle 93 of the support tube 92, which is suitable for the clamping stroke of the cable with the corresponding diameter. At this time, the external negative pressure equipment is started. The negative pressure is transmitted through the movable tube 94, the open arc groove, the air nozzle 93 and the hose to the suction hood 141 on the guide plate 14, so that the suction hood 141 generates suction force to absorb and collect the metal chips generated during the cutting process.
[0068] When the cutting is completed and the concave frames 84 move away from each other, the rack 113 moves in the opposite direction with the concave frame 84, driving the second gear 111, transmission shaft 110 and other components to reverse the transmission, so that the movable tube 94 rotates to the initial state where the open arc groove and the air nozzle 93 are misaligned, and the negative pressure channel is closed. This not only prevents impurities from entering the tube when not in operation, but also, in conjunction with the tilting and resetting of the guide plate 14, allows the sampling end to slide smoothly into the roller conveyor 7.
[0069] Working principle: After the equipment is started, it first enters the cable feeding stage. The operator places the cable to be sampled on the U-shaped support frame 21 of the support component 2. The cable tail end is evenly supported by the support frame 201 to ensure that the cable is placed stably. Then, the clamping unit one starts. The gear motor 212 drives the first bidirectional lead screw 210 to rotate through the belt drive unit one 211. Under the guiding and limiting action of the guide rail two 27 and the slider two 28, the two sets of sliding seats two drive the clamping plate one 26 to move closer synchronously and clamp one end of the cable. Then the moving unit starts to move. The drive motor drives the lead screw one 241 to rotate through the coupling, so that the sliding seat one drives the entire clamping unit one and the cable along the guide rail one 23 to feed towards the cutting station until the cable sampling end reaches the preset position between the clamping component 6 and the clamping unit three 8, and the feeding action stops.
[0070] After the cable is fed into position, the positioning, clamping, and chip collection preparation stage begins. In clamping assembly 6, two sets of support rollers 62 support the cable to ensure its horizontal posture, and guide rollers 63 laterally limit the cable to prevent it from shifting. At the same time, clamping unit 2 64, driven by belt drive unit 2 65, moves clamping plate 2 641 closer through a transmission structure similar to clamping unit 1, clamping both sides of the cable cutting position. Since the third bidirectional lead screw is linked to belt drive unit 2 65 via pulley 1 812, the two sets of concave frames 84 of clamping unit 3 8 move closer synchronously with clamping plate 2 641, causing clamping plate 3 841 to clamp the cable sampling end.
[0071] During this process, the linkage unit of the transmission component 1 starts to work. The concave frame 84 moves through the sliding sleeve 17 and the mounting sleeve 18, pulling the rack 19 to move. Through the meshing of the first gear 16, the bearing shaft 15, and the second bevel gear 121 and the third bevel gear, the guide plate 14 is driven to overcome the elastic force of the torsion spring 13 and turn from inclined to horizontal. At the same time, the transmission unit of the collection component 9 operates synchronously. The concave frame 84 drives the rack 113 to move. Through the meshing of the second gear 111, the transmission shaft 110, and the fourth bevel gear and the first bevel gear 95, the movable tube 94 is driven to rotate, so that the opening arc groove of the movable tube 94 is aligned with the air nozzle 93 of the support tube 92, opening the negative pressure channel and preparing for chip collection.
[0072] After positioning and clamping are completed, the cutting execution stage begins. First, the holding assembly 4 is activated, and the linear electric cylinder 42 on the mounting frame 41 drives the holding end 43 to move downward, contacting the upper end of the cable and applying a preset pressure to clamp and fix the cable from above, preventing it from tilting or shifting during cutting. Then, the cutting assembly 5 starts working, and the reduction motor 54 drives the transmission wheel 52 to rotate, causing the band saw 53 to run continuously. At the same time, the lifting unit 56 drives the sliding seat 59 to move the support frame 510 and the frame box 51 downward as a whole, so that the high-speed rotating band saw 53 can cut the cable perpendicularly.
[0073] During the cutting process, the external negative pressure device is activated. The negative pressure is transmitted through the movable pipe 94, the open arc groove, the air nozzle 93 and the hose to the suction hood 141 on the guide plate 14, which adsorbs and collects the metal chips generated during cutting in real time, preventing the chips from falling into the equipment and affecting the operation of the transmission components. The telescopic plate 142 and telescopic plate 143 on the side of the guide plate 14 are in a retracted and fitted state, which does not affect the cutting action.
[0074] After cutting, the sampling end conveying and equipment reset stage begins. The lifting unit 56 of the cutting assembly 5 drives the cutting unit to reset upwards, and the band saw 53 stops operating; the linear electric cylinder 42 of the holding assembly 4 drives the holding end 43 to reset upwards, and the clamping unit 2 64 and clamping unit 3 8 move synchronously, respectively driving the clamping plate 2 641 and clamping plate 3 841 away from the release cable. During the process of the concave frame 84 of clamping unit 3 8 moving away, the transmission unit drives the movable tube 94 to rotate in the opposite direction, causing the open arc groove and the air nozzle 93 to be misaligned, closing the negative pressure channel, and the negative pressure equipment stops working; the rack 19 of the linkage unit resets under the action of the tension spring 181, the guide plate 14 returns to its tilted state under the preload of the torsion spring 13, and the nested telescopic plate 142 and telescopic plate 2 143 extend synchronously. The cut cable sampling end falls onto the inclined guide plate 14 and slides along the inclined guide plate 14 into the roller conveyor 7 below. The roller conveyor 7 transports the sampling end to the outside of the equipment box 213 for collection. If there are any residual chips, they fall into the collection box 71 on the side frame of the roller conveyor 7. Finally, the moving unit drives the clamping unit to reset, waiting for the next sampling operation. The whole process achieves fully automatic closed-loop operation.
