Description

Technical Field

[0001] The invention relates to the technical field of cable detection, in particular to a cable positioning, stripping and sampling device. Background Art

[0002] The cable heat shrinkage test is to simulate the high temperature of the cable sample in the laboratory to determine the cable heat shrinkage performance. Before the test, it is necessary to draw a marking line with a spacing of 200mm in the center of the cable insulation layer, remove part of the insulation layer at both ends, leaving a section of about 205mm in length in the middle (do not cut to the marking line), and then place the sample in a high temperature box for static.

[0003] In existing technology, manual or automated cutting is commonly used. Manual cutting is inefficient, the ends are uneven, and the length of the test section left after cutting the sample in the middle is subject to large errors. Automated cutting requires consideration of precision and accuracy.

[0004] Accuracy issues often arise due to errors in the fixture. Existing equipment uses pneumatic cylinders at both ends, which are then clamped together. This solution can lead to inaccurate reference surfaces, especially since the stroke, speed, and errors of the two cylinders affect the reference position after positioning. Compensation can only be achieved by adjusting the tool position later, which places an algorithmic burden. Furthermore, tool compensation cannot solve the problem all at once; individual movement compensation must be performed during each circular cutting step, significantly impacting efficiency.

A pressing roller is installed at the bottom of the upper pressing platform. The pressing roller is driven to rotate around its own axis. When the cable is pressed against the lower supporting platform by the upper pressing platform, the pressing roller is driven to rotate, and the cable rotates through friction transmission.

[0014] Preferably, the middle portion of the lower support platform is an upwardly open V-shaped positioning groove, and rollers are installed at both ends of the V-shaped positioning groove.

[0015] Preferably, the stripping knife of the tool mechanism is fixed to the front end of the carrier plate, and a screw rod is installed in the middle of the carrier plate, and the screw rod drives the carrier plate to slide.

[0016] Preferably, the stripping station further comprises a vertically arranged mounting base plate, the mounting base plate being used to mount the remaining mechanical mechanisms on the stripping station, wherein:

[0017] The axial positioning mechanism is arranged along the horizontal direction of the mounting base plate, and the vertical positioning mechanism is arranged along the vertical direction of the mounting base plate.

[0018] A through hole is provided on the mounting base plate for the stripping knife to extend out, and a carrier plate for mounting the stripping knife and a screw rod for driving the carrier plate to move are located on the back of the mounting base plate.

[0022] Preferably, the pulling assembly is mounted on the mounting plate of the reference positioning portion, the pulling assembly includes a vertically arranged vertical plate, a pulling card block is slidably connected to the side of the vertical plate, the rear end of the vertical plate is connected to a horizontal cylinder for driving the vertical plate to slide horizontally relative to the mounting plate, a vertical cylinder is fixedly mounted on the back of the vertical plate, and the output end of the vertical cylinder is connected to the pulling card block for driving the pulling card block to slide vertically relative to the vertical plate.

[0023] Preferably, it also includes a coding and marking station, which includes a lower support roller group, a side support roller group, and a coding machine group located above the lower support roller group;

[0024] The lower support roller set is configured to slide up and down to adjust the vertical position;

[0030] Compared with the prior art, the present invention has the following advantages: a reference positioning portion is designed on the axial positioning mechanism. The reference positioning portion with a fixed position serves as the reference position for each cable clamping, so that the cable clamping position remains unchanged each time. The tool mechanism only needs to retain the degree of freedom in one direction for driving, thereby saving operating costs and sample preparation efficiency.

[0031] Only the reference positioning portion utilizes a locating pin for positioning. This portion does not have an independent drive source, but instead uses a spring and locating pin as the active drive source. The spring can only control the reference positioning head's short-distance movement, remaining within the positioning range of the locating pin. Extending the locating pin pushes it to the reference position. The spring's purpose is to enable movement, ensuring that once circumcision is complete, the axial clamping structure (i.e., the locating heads at each end) must be immediately separated from the cable end to prevent the remaining cable sheath from being affected by the internal stresses of the circumcision. Furthermore, the retraction of the locating heads facilitates the removal of waste material from the circumcision at both ends by the puller assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-11 As shown, the present invention provides a technical solution: a cable positioning stripping and sampling device. As one of the design points of this embodiment, the positioning mechanism of the sample stripping and sampling is optimized, as follows:

[0046] Including stripping station 3, stripping station 3 is provided with:

[0047] Axial positioning mechanism: The axial positioning mechanism is used to provide pressure at both ends of the cable along the cable axis to fix and clamp the cable. It includes a reference positioning portion 33 at one end and an active positioning portion 34 at the other end;

[0048] The reference positioning portion 33 includes a reference positioning head 336 that can be extended and retracted along the cable axis, and a positioning pin 3381. The positioning pin 3381 is used to limit the reference positioning head 336 to a reference position in the axial direction. An elastic component is provided at the rear end of the reference positioning head 336, which causes the reference positioning head 336 to have a tendency to retract backward in the reference position.

[0049] Specific reference Figure 4 as well as Figure 5 As shown, the reference positioning portion 33 includes a vertically arranged mounting plate 3363. A connecting shaft 3362 is mounted on the rear end of the reference positioning head 336. The connecting shaft 3362 is slidably connected to the mounting plate 3363. A back plate 3365 is fixedly mounted on the rear end of the connecting shaft 3362. A spring 3364 is connected between the back plate 3365 and the mounting plate 3363. In other words, the spring 3364 serves as the elastic member mentioned above.

[0050] Further references Figure 5 as well as Figure 6 As shown in the figure, the installation structure of the positioning pin 3381 is arranged in a vertical direction. The bottom of the positioning pin 3381 is connected to the positioning cylinder 338 for driving the positioning pin 3381 to slide up and down. The bottom of the connecting shaft 3362 is fixedly mounted with a positioning plate 3361. The upper end of the positioning pin 3381 has a tapered structure that is thinner at the top and thicker at the bottom. Below the tapered structure is a cylindrical structure. The positioning plate 3361 is provided with a positioning hole 3360 that matches the tapered structure. The upper sidewall of the positioning hole 3360 is vertical, and the lower sidewall is a downwardly flared inclined surface.

[0051] The reference positioning head 336 has two working positions during operation. One is the reference position where the positioning pin 3381 extends and limits the reference positioning head 336. The other is the initial position where the positioning pin 3381 retracts downward and the reference positioning head 336 retracts backward under the action of the spring 3364. Therefore, in actual implementation, it should be noted that when the spring 3364 pulls the reference positioning head 336 back, the positioning hole 3360 and the positioning pin 3381 cannot be completely offset in the vertical direction. Figure 6 As shown, both the positioning pin 3381 and the positioning hole 3360 are narrow at the top and wide at the bottom. When the spring 3364 pulls the positioning plate 3361 back a certain distance, the upper portion of the positioning pin 3381 is still at the lower portion of the positioning hole 3360. When the positioning pin 3381 slides upward, it can still be inserted into the positioning hole 3360. The tapered inclined surface at the upper portion of the positioning pin 3381 and the inclined surface at the lower portion of the positioning hole 3360 guide the positioning plate 3361 forward. Finally, the cylindrical portion of the positioning pin 3381 enters the upper portion of the positioning hole 3360, and the positioning pin 3381 stops rising, thus achieving the positioning of the positioning plate 3361. That is, the reference positioning head 336 remains in the reference position.

[0052] In addition to limiting and blocking, the positioning pin 3381 also needs to provide horizontal forward pushing for the reference positioning head 336 during the extension process. In the existing mechanism, vertical motion is converted into horizontal displacement, and the conventional structures used include wedge-shaped inclined blocks, rack structures, etc. However, these structures can only meet the conversion of displacement and cannot guarantee the effect of forced limiting after displacement. For example, the conventional wedge-shaped inclined block is driven by the relative friction of the inclined surfaces to achieve the change of thrust direction, and the two inclined surfaces remain in contact after being pushed into place. In the subsequent clamping, the reference positioning head 336 as the reference surface remains fixed, and the other end continues to apply pressure toward the reference positioning head 336. Due to problems with manufacturing accuracy, the wedge-shaped inclined block may be offset, thereby affecting the determination of the reference position. The positioning pin 3381 of this embodiment achieves guided pushing through the conical structure at the top and limiting through the cylindrical structure at the bottom, and the pushing function and limiting function are independently realized through two-section structures. When pressure is applied from the other end toward the reference positioning head 336 , the cylindrical portion of the positioning pin 3381 is subjected to horizontal pressure and does not cause vertical displacement thereof, so that the positioning pin 3381 can achieve stable positioning.

[0053] The active positioning portion 34 includes an active positioning head 341 and a driving portion for driving the active positioning head 341 to extend and retract along the cable axis; Figure 7 As shown, the active positioning portion 34 is located on the left and right sides of the reference positioning portion 33. The two structures are essentially the same, differing in that the rear end of the reference positioning head 336 is connected to a spring 3364 for passive displacement, while the rear end of the active positioning head 341 of the active positioning portion 34 is equipped with an active cylinder 342 for active displacement.

[0054] It is worth mentioning that, referring to Figure 4 In the figure, an inverted V-shaped baffle 335 is provided above the reference positioning head 336. The baffle 335 is used to block the waste chips generated during cable ring cutting and guide them to the sides to prevent the displacement of the reference positioning head 336 from being affected. The baffle 335 can be installed on the active positioning head 341, or it can be not installed. This is because the reference positioning head 336 must absolutely maintain its position after displacement to avoid deviation. At the same time, the reference positioning head 336 is passively displaced by the action of the spring 3364 and is more easily affected by waste chips. The active positioning head 341 is actively driven by a cylinder and is less affected by waste chips.

[0055] The vertical positioning mechanism 32 is used to clamp the cable in a direction perpendicular to the cable axis; the vertical positioning mechanism 32 includes an upper pressing platform 328 and a lower supporting platform 326 that can slide downward in a direction perpendicular to the cable axis, Figure 3As shown, the upper pressing platform 328 and the lower supporting platform 326 are both installed on vertically arranged slide rails. The first motor 3281 drives the screw module to control the sliding of the upper pressing platform 328, and the second motor 3261 drives the screw mold to control the up and down sliding of the lower supporting platform 326.

[0056] The bottom of the upper pressing platform 328 is provided with a pressing roller 327, which is driven by the third motor 322 and can rotate around its own axis. Figure 2 As shown, the third motor 322 transmits torque to the pressing roller 327 through the transmission of the belt 323. When the cable is pressed against the lower support platform 326 by the upper pressing platform 328, the pressing roller 327 is driven to rotate, and the cable is rotated through friction transmission.

[0057] The middle portion of the lower support platform 326 is a V-shaped positioning groove that opens upward, and rollers 325 are installed at both ends of the V-shaped positioning groove.

[0058] Reference Figure 1 As shown, in the overall coordinate system of the stripping station 3, a vertically arranged mounting base plate 321 is included. The mounting base plate 321 is used to mount the remaining mechanical mechanisms on the stripping station 3, wherein:

[0059] The axial positioning mechanism is arranged horizontally along the mounting base plate 321 , and the vertical positioning mechanism 32 is arranged vertically along the mounting base plate 321 .

[0060] The tool mechanism includes a stripping knife 324 and a driving unit for driving the stripping knife 324 to complete the ring cutting of the cable; Figure 2 and Figure 3 As shown, the stripping knife 324 of the tool mechanism is fixed to the front end of the carrier plate 329, and a screw rod 3291 is installed in the middle of the carrier plate 329, and the screw rod 3291 drives the carrier plate 329 to slide. That is, the screw rod 3291 acts as a driving part to drive the stripping knife 324 to move. Figure 3 A through hole is provided on the mounting substrate 321 for the stripping knife 324 to extend out, and a carrier plate 329 for mounting the stripping knife 324 and a screw rod 3291 for driving the carrier plate 329 to move are located on the back of the mounting substrate 321 .

[0061] It is worth mentioning that the tool mechanism must eventually complete the circular cutting of both ends of the cable. Figure 11 As shown, Figure 11After the cable A is circumferentially cut, slit grooves are cut out at the positions of the insulation layers at both ends. Therefore, two groups of stripping knives 324 are provided and installed on the carrier 329 at intervals. The present application installs a power supply at the rear end of the two stripping knives 324, that is, the positive pole of the power supply is connected to one group of stripping knives 324, and the negative pole of the power supply is connected to the other group of stripping knives 324. An electric meter is connected to the circuit. When the tool mechanism is advancing, the insulation layer is completely cut in, and when the tool contacts the battery core inside the cable, a path is formed between the two groups of tools and the cable battery core. The electric meter detects the path, and if an ammeter is used, a current signal is collected. It is then determined that the circumferential cutting is completed, and the tool mechanism stops advancing.

[0062] The pulling assembly includes a pulling card block 334, which is provided with an inverted V-shaped slot for pulling the waste cut by the stripping knife 324 out from the cable end; the pulling assembly is installed on the mounting plate 3363 of the axial positioning mechanism, and the pulling assembly includes a vertically arranged vertical plate 3341, and the pulling card block 334 is slidably connected to the side of the vertical plate 3341. The rear end of the vertical plate 3341 is connected to a horizontal cylinder 332 for driving the vertical plate 3341 to slide horizontally relative to the mounting plate 3363. The back of the vertical plate 3341 is fixedly installed with a vertical cylinder 333, and the output end of the vertical cylinder 333 is connected to the pulling card block 334 for driving the pulling card block 334 to slide vertically relative to the vertical plate 3341.

[0063] Reference Figure 5 as well as Figure 6 As shown, the reference positioning portion 33 and the active positioning portion 34 are each combined to form a puller assembly. The entire assembly comprises a vertically mounted support panel 331, onto which a mounting plate 3363 is slidably mounted. The bottom of the mounting plate 3363 is driven by an adjustable cylinder 337 to slide up and down.

[0064] Reference Figure 4 、 Figure 5 as well as Figure 11 As shown, during the pulling operation, the reference positioning head 336 and the active positioning head 341 withdraw, releasing the middle cable. The adjusting cylinder 337 drives the mounting plate 3363 downward, at which point the reference positioning portion 33, the active positioning portion 34, and the respective pulling components move downward together. The movement of the positioning portion causes the positioning head to be offset from the cable, leaving space for the waste to be pulled out. The pulling component moves downward, bringing it into a position nearly flush with the cable. Subsequent vertical adjustments are achieved using the vertical cylinder 333, which engages the V-shaped slot of the pulling block 334 with the cutting groove of the cable.

[0065] The vertical cylinder 333 is used to lift the pulling block 334 so that it is above the cable. The horizontal cylinder 332 is used to adjust the horizontal position of the pulling block 334 so that it extends out and is opposite to the two annular grooves. The vertical cylinder 333 is then used to control the pulling block 334 to descend and clamp the annular grooves. Finally, the horizontal cylinder 332 is retracted to pull out the waste.

[0066] The processing steps of the stripping station 3 are configured as follows: when the cable is supported by the vertical positioning mechanism 32 in the axial positioning mechanism, the positioning pin 3381 limits the reference positioning head 336 to the reference position, the active positioning head 341 extends to push the cable against the end of the reference positioning head 336, and the stripping knife 324 performs a circular cut on the cable;

[0067] After the stripping knife 324 completes the circular cutting, the positioning pin 3381 disengages from the reference positioning head 336, the reference positioning head 336 retracts, and the active positioning head 341 retracts synchronously. When the stripping knife 324 completes the circular cutting, the axial positioning head needs to be withdrawn in time to avoid the insulating material being squeezed against the waste material and the retained material due to the internal stress, thereby affecting the subsequent experimental results. From this motivation, it can be seen that although the reference position needs to be kept relatively fixed, considering the above-mentioned exit positioning problem, the reference position cannot be absolutely fixed. Therefore, the present application adopts a combination of elastic components and positioning pins 3381, which can improve the positioning accuracy and ensure the stripping accuracy, and it is easier to control the positioning head to release the clamping state. Finally, it is also beneficial for the pulling assembly to pull out the waste material.

[0068] Reference Figure 8 As shown, it also includes a coding and marking station 1, such as Figure 9 As shown, the coding and marking station 1 includes a lower support roller group 17, a side support roller group 16, and a coding machine group 15 located above the lower support roller group 17;

[0069] The lower support roller set 17 is configured to slide up and down to adjust the vertical position, such as Figure 9 As shown, the bottom of the lower support roller group 17 is connected to the support cylinder 18 to achieve up and down sliding;

[0070] The side support roller group 16 is driven by the fourth motor 19, referring to Figure 9 The output end of the fourth motor 19 is connected to the transmission belt 191 to drive the side support roller group 16. When the cable is placed on the side support roller group 16, the cable can be driven to rotate synchronously through friction;

[0071] The inkjet printer unit 15 is provided with a pressure wheel 151 on both sides, and the inkjet printer unit 15 is configured to slide in the horizontal direction and the vertical direction. Figure 9As shown, the back of the inkjet printer unit 15 is equipped with a mounting surface 12, which is equipped with a horizontal module 13. The frame housing the inkjet printer unit 15 is mounted on this horizontal module 13. A vertical module 14 is mounted on the frame body, driving the inkjet printer unit 15 to slide up and down. The inkjet printer unit 15 has two functions: first, it marks lines centered on the cable insulation layer at intervals of 200 mm. After the cable is left at high temperature, the changes in the marking lines are measured to determine the axial shrinkage of the insulation layer. Second, it distinguishes the cable coding as a test item, facilitating subsequent tracking of test data.

[0072] Continue to refer to Figure 8 As shown, it also includes a manipulator 6, which is installed at the front end of a three-axis manipulator 5, and the three-axis manipulator 5 is configured on a section of the transverse movement module 4;

[0073] Structural reference of robot 6 Figure 10 As shown, it includes a movable clamping jaw 61 driven by a clamping cylinder 63 and a fixed clamping jaw 62. A distance measuring sensor is provided at the bottom of the movable clamping jaw 61 for measuring the distance between the two clamping jaws. When clamping the cable, the diameter of the cable can be obtained from this.

[0074] The coding and marking station 1 and the stripping and cutting station 3 are arranged in sequence along the direction of the transverse module 4, so that the robot 6 can load and unload the coding and marking station 1 and the stripping and cutting station 3; Figure 8 As shown, a silo 31 is provided at the bottom of the stripping station 3 .

[0075] A temporary storage bracket 11 is provided in the area between the coding and marking station 1 and the stripping station 3, and a pre-storage bracket 2 is provided on the side of the stripping station 3 away from the coding and marking station 1. The design of the temporary storage bracket 11 and the pre-storage bracket 2 are both to meet the needs of the processing rhythm. In actual work, the cable is first loaded onto the coding and marking station 1 for marking. After the marking work is completed, it is transferred to the stripping station 3. If the stripping station 3 is being processed at this time, it is placed on the temporary storage bracket 11. After the stripping station 3 is completed, the completed cable is transferred to the pre-storage bracket 2, and the cable on the temporary storage bracket 11 is transferred to the stripping station 3, and so on, to achieve fully automated loading and unloading processes.
