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, cut off 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 to stand.

[0003] In the prior art, manual or automated equipment is usually used for ring cutting. Manual ring cutting is inefficient, the ends are not aligned, and the length error of the test section left after cutting the middle of the sample is large. For automated equipment ring cutting, the problem of precision and accuracy needs to be considered.

[0004] Usually, accuracy issues are caused by errors in fixtures. Existing equipment uses a solution that sets cylinders at both ends and then clamps them. This solution may cause inaccurate reference surfaces, especially the stroke, speed and error of the two cylinder drives will affect the reference position after positioning. The only way to compensate is to adjust the position of the tool later, which will bring a burden on the algorithm. In addition, tool compensation cannot solve the problem at one time. It is necessary to perform movement compensation separately in each circular cutting step, which greatly affects efficiency. Summary of the invention

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

[0008] Preferably, the middle part of the lower supporting table is a V-shaped positioning groove with an upward opening, and supporting rollers are installed at both ends of the V-shaped positioning groove.

[0009] Preferably, the stripping knife of the tool mechanism is fixed at the front end of the carrier plate, and a lead screw is installed in the middle of the carrier plate, and the lead screw drives the carrier plate to slide.

[0010] Preferably, the stripping station further includes a vertically arranged mounting substrate for mounting the remaining mechanical mechanisms on the stripping station, where: The axial positioning mechanism is arranged horizontally left and right along the mounting substrate, and the vertical positioning mechanism is arranged vertically up and down along the mounting substrate; Through holes are opened on the mounting substrate for the stripping knife to extend out.

[0011] Preferably, the reference positioning part includes a vertically arranged mounting plate. A connecting shaft is installed at the rear end of the reference positioning head, and the connecting shaft is slidably connected to the mounting plate.

[0012] Preferably, the positioning pin is arranged in the vertical direction, and a positioning cylinder for driving the positioning pin to slide up and down is connected to the bottom of the positioning pin; A positioning plate is fixedly installed at the bottom of the connecting shaft. The positioning pin is a tapered structure with a thinner upper part and a thicker lower part, and a positioning hole matching the tapered structure is opened on the positioning plate.

[0013] Preferably, the pulling component is installed on the mounting plate of the reference positioning part. The pulling component includes a vertically arranged vertical plate. A pulling block is slidably connected to the side of the vertical plate. A horizontal cylinder is connected to the rear end of the vertical plate for driving the vertical plate to slide horizontally relative to the mounting plate. A vertical cylinder is fixedly installed on the back of the vertical plate, and the output end of the vertical cylinder is connected to the pulling block for driving the pulling block to slide vertically relative to the vertical plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention designs a reference positioning part on the axial positioning mechanism. Through the reference positioning part with a fixed position, as the reference position for each cable clamping, the position of each cable clamping remains unchanged, and the tool mechanism only needs to retain the degree of freedom drive in one direction, saving operation costs and sample preparation efficiency; Only the reference positioning part of the part uses a positioning pin for positioning, and at the same time, the reference positioning part does not install an independent drive source. Instead of the active drive source, a spring and a positioning pin are used. The spring can only control the reference positioning head to move a short distance, and its movement range is still within the positioning range of the positioning pin. After the positioning pin extends, it can push it to the reference position. The function of the spring to make it move is that when the circumferential cutting is completed, it is necessary to immediately separate the axial clamping structure (i.e., the positioning heads at both ends) from the cable end to avoid the influence of the internal stress of the remaining cable sheath after circumferential cutting. In addition, after the positioning head retracts, it is also convenient for the pulling component to pull out the waste materials cut from both ends. Brief Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-11 shown, the present invention provides a technical solution: a cable positioning, stripping and sample preparation device. As one of the design key points of this embodiment, an optimized design is carried out on the positioning mechanism for sample preparation and stripping, specifically as follows: including a stripping station 3, and the stripping station 3 is provided with: Axial positioning mechanism: The axial positioning mechanism is used to provide pressure at both ends of the cable along the cable axis direction to fixedly clamp the cable, including a reference positioning part 33 at one end and an active positioning part 34 at the other end; The reference positioning part 33 includes a reference positioning head 336 that can expand and contract along the cable axis direction and a positioning pin 3381. The positioning pin 3381 is used to limit the reference positioning head 336 at the reference position in the axial direction. An elastic member is provided at the rear end of the reference positioning head 336, and the elastic member causes the reference positioning head 336 to have a tendency to retract backward at the reference position; Specifically refer to Figure 4 and Figure 5 As shown, the reference positioning part 33 includes a vertically arranged mounting plate 3363. A connecting shaft 3362 is installed at 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 installed at the rear end of the connecting shaft 3362. A spring 3364 is connected between the back plate 3365 and the mounting plate 3363. That is, the spring 3364 is used as the elastic member mentioned above.

[0021] Further refer to Figure 5 and Figure 6 As shown, the installation structure of the positioning pin 3381 is as shown in the figure. The positioning pin 3381 is arranged in the vertical direction. A positioning cylinder 338 for driving the positioning pin 3381 to slide up and down is connected to the bottom of the positioning pin 3381. A positioning plate 3361 is fixedly installed at the bottom of the connecting shaft 3362. The upper end of the positioning pin 3381 is a tapered structure with a thinner upper part and a thicker lower part. Below the tapered structure is a cylindrical structure. A positioning hole 3360 matching the tapered structure is opened on the positioning plate 3361. The upper side wall of the positioning hole 3360 is vertical, and the lower side wall is an inclined surface shape that expands downward.

[0022] The reference positioning head 336 has two working positions during operation. One is the reference position where the reference positioning head 336 is limited when the positioning pin 3381 extends, and the other is the initial position where the reference positioning head 336 retracts backward under the action of the spring 3364 when the positioning pin 3381 retracts downward. Therefore, in actual implementation, it should be noted that when the spring 3364 pulls back the reference positioning head 336, the positioning hole 3360 and the positioning pin 3381 cannot be completely offset in the vertical direction. Refer to Figure 6As shown, both the positioning pin 3381 and the positioning hole 3360 have a structure that is narrower at the top and wider at the bottom. After the spring 3364 pulls the positioning plate 3361 backward by a certain distance, the upper part of the positioning pin 3381 is still below the lower part of the positioning hole 3360. When the positioning pin 3381 slides upward, it can still be inserted into the positioning hole 3360, and is guided by the inclined surfaces of the upper conical part of the positioning pin 3381 and the lower inclined surface of the positioning hole 3360 to push the positioning plate 3361 forward. Finally, the cylindrical part of the positioning pin 3381 enters the upper part of the positioning hole 3360, and the positioning pin 3381 stops rising, realizing the positioning of the positioning plate 3361, that is, the reference positioning head 336 is maintained in the reference position.

[0023] In addition to limiting and blocking, the positioning pin 3381 also needs to provide a forward push in the horizontal direction to the reference positioning head 336 during its extension process. In the existing mechanisms, the common structures used to convert vertical movement into horizontal displacement include wedge-shaped blocks, racks, and other structures. However, these structures can only meet the conversion of displacement and cannot guarantee the effect of forced limiting after displacement. For example, in a conventional wedge-shaped block, the relative friction of the inclined surface is used to drive to change the direction of the thrust force, and the two inclined surfaces remain in contact after the push is in place. During subsequent clamping, the reference positioning head 336 as the reference surface remains fixed, and pressure is continuously applied to the other end towards the reference positioning head 336. Due to manufacturing precision problems, the wedge-shaped block may shift, thus affecting the determination of the reference position. In this embodiment, the positioning pin 3381 realizes guiding and pushing through the conical structure at the top and performs limiting through the cylindrical structure at the lower part, independently realizing the pushing function and the limiting function through two sections of structures. When pressure is applied to the other end towards the reference positioning head 336, the cylindrical part of the positioning pin 3381 bears the horizontal pressure and will not cause its vertical displacement, and the positioning pin 3381 can achieve stable limiting.

[0024] The active positioning part 34 includes an active positioning head 341 and a driving part that drives the active positioning head 341 to expand and contract along the cable axis direction; referring to Figure 7 As shown, the structures of the active positioning part 34 and the reference positioning part 33 are arranged on the left and right sides respectively. And their structures are basically the same. The difference is 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 part 34 is installed with an active cylinder 342 for active displacement.

[0025] It is worth mentioning that referring to Figure 4In the [description], a V-shaped baffle 335 is provided in the upper direction of the reference positioning head 336. The baffle 335 is used to block the waste chips generated during the cable circumcision and export them to both sides to prevent affecting the position of the reference positioning head 336 during displacement. The baffle 335 can be installed or not installed at the active positioning head 341. The reason is that the reference positioning head 336 needs to absolutely ensure the 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, while the active positioning head 341 is actively driven by a cylinder and is less affected by waste chips.

[0026] 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 table 328 and a lower support table 326 that can slide up and down in a direction perpendicular to the cable axis. Refer to Figure 3 As shown, both the upper pressing table 328 and the lower support table 326 are installed on the vertically arranged slide rails. The first motor 3281 drives the lead screw module to control the sliding of the upper pressing table 328, and the second motor 3261 drives the lead screw die to control the up and down sliding of the lower support table 326.

[0027] A pressure roller 327 is installed at the bottom of the upper pressing table 328. The pressure roller 327 can rotate around its own axis driven by the third motor 322. Refer to Figure 2 As shown, the third motor 322 transmits the torque to the pressure roller 327 through the transmission of the belt 323. When the cable is pressed by the upper pressing table 328 against the lower support table 326, the pressure roller 327 is driven to rotate, and the cable is rotated through frictional transmission.

[0028] The middle part of the lower support table 326 is a V-shaped positioning groove with an upward opening. Support rollers 325 are installed at both ends of the V-shaped positioning groove.

[0029] Refer to Figure 1 As shown, in the overall coordinate system of the stripping station 3, it includes a vertically arranged mounting substrate 321. The mounting substrate 321 is used to mount the remaining mechanical mechanisms on the stripping station 3, where: The axial positioning mechanism is arranged horizontally left and right along the mounting substrate 321, and the vertical positioning mechanism 32 is arranged vertically up and down along the mounting substrate 321; The tool mechanism includes a stripping knife 324 and a driving part that drives the stripping knife 324 to complete the circumcision of the cable; Refer to Figure 2 and Figure 3 As shown, the stripping knife 324 of the tool mechanism is fixed at the front end of the carrier plate 329. A lead screw 3291 is installed in the middle of the carrier plate 329. The lead screw 3291 drives the carrier plate 329 to slide. That is, the lead screw 3291 serves as the driving part to drive the movement of the stripping knife 324. Refer to Figure 3, a through hole is formed in the mounting substrate 321 for the stripping cutter 324 to extend out. The carrier plate 329 for mounting the stripping cutter 324 and the lead screw 3291 for driving the movement of the carrier plate 329 are located on the back surface of the mounting substrate 321.

[0030] It is worth mentioning that the tool mechanism ultimately needs to complete the circumferential cutting of both ends of the cable. Refer to Figure 11 as shown. Figure 11 For the cable A after circumferential cutting, the positions of the insulating layers at both ends are shown, and a slit groove is cut out. Therefore, two sets of stripping cutters 324 are provided and are installed on the carrier plate 329 at intervals. In this application, a power supply is installed at the rear ends of the two stripping cutters 324, that is, the positive pole of the power supply is connected to one set of stripping cutters 324, and the negative pole of the power supply is connected to the other set of stripping cutters 324. And an ammeter is connected in the circuit. When the tool mechanism is feeding, when the insulating layer is completely cut into and the tool contacts the battery core inside the cable, a circuit is formed between the two sets of tools and the cable battery core. The ammeter detects the circuit. If an ammeter is used, a current signal is collected. Then it is judged that the circumferential cutting is completed, and the tool mechanism stops feeding.

[0031] The pulling component includes a pulling block 334. The pulling block 334 is provided with an inverted V-shaped card slot for pulling out the waste material cut by the stripping cutter 324 from the end of the cable. The pulling component is installed on the mounting plate 3363 of the axial positioning mechanism. The pulling component includes a vertically arranged vertical plate 3341. The pulling block 334 is slidably connected to the side of the vertical plate 3341. A horizontal cylinder 332 is connected to the rear end of the vertical plate 3341 for driving the vertical plate 3341 to slide horizontally relative to the mounting plate 3363. A vertical cylinder 333 is fixedly installed on the back of the vertical plate 3341. The output end of the vertical cylinder 333 is connected to the pulling block 334 for driving the pulling block 334 to slide vertically relative to the vertical plate 3341.

[0032] Refer to Figure 5 and Figure 6 as shown. One set of pulling components is respectively combined and installed on the reference positioning part 33 and the active positioning part 34. The whole assembly includes a vertically arranged support panel 331. The mounting plate 3363 is slidably installed on the support panel 331. The bottom of the mounting plate 3363 is driven by an adjusting cylinder 337 to slide up and down.

[0033] Refer to Figure 4 , Figure 5 and Figure 11As shown, during the drawing operation, the reference positioning head 336 and the active positioning head 341 retract, releasing the cable in the middle. The adjusting cylinder 337 drives the mounting plate 3363 downward. At this time, the reference positioning part 33, the active positioning part 34, and their respective combined drawing components move downward together. The movement of the positioning part causes the positioning head to be displaced from the cable, leaving space for pulling out the waste material. The drawing component moves downward to a position close to being flush with the cable. Subsequent vertical adjustment is achieved by the vertical cylinder 333. The V-shaped card slot of the drawing block 334 is engaged with the cutting slot of the cable.

[0034] The drawing block 334 is lifted by the vertical cylinder 333 to be above the cable. The horizontal cylinder 332 adjusts the horizontal position of the drawing block 334 to extend and be opposite to the two circumferential cutting slots. Then, the vertical cylinder 333 controls the drawing block 334 to descend and clamp the circumferential cutting slots. Finally, the horizontal cylinder 332 retracts backward to pull out the waste material.

[0035] The processing steps of the stripping station 3 are configured as follows: when the cable is supported in the axial positioning mechanism by the vertical positioning mechanism 32, the positioning pin 3381 positions the reference positioning head 336 at 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 circumferential cut on the cable. After the stripping knife 324 completes the circumferential cut, the positioning pin 3381 disengages from the reference positioning head 336, and the reference positioning head 336 retracts. The active positioning head 341 retracts synchronously. After the stripping knife 324 completes the circumferential cut, the axial positioning head needs to retract in a timely manner to avoid the insulation material being squeezed between the waste material and the retained material due to internal stress, which affects the subsequent experimental results. From this motivation, it can also be seen that although the reference position needs to be relatively fixed, considering the above-mentioned problem of withdrawing the positioning, the reference position cannot be absolutely fixed. Therefore, in this application, the elastic component is combined with the positioning pin 3381, which can more easily control the positioning head to release the clamping state on the premise of improving the positioning accuracy and ensuring the stripping accuracy. Finally, it is also beneficial for the drawing component to pull out the waste material.

[0036] Refer to Figure 8 As shown, it also includes the inkjet marking and scribing station 1. As Figure 9 shown, the inkjet marking and scribing station 1 includes a lower support roller group 17, a side support roller group 16, and an inkjet marking unit 15 located above the lower support roller group 17. The lower support roller group 17 is configured to slide up and down to adjust the vertical position. As Figure 9 shown, the bottom of the lower support roller group 17 is connected to a support cylinder 18 to achieve up and down sliding. The side support roller group 16 is driven by the fourth motor 19. Refer to Figure 9, The output end of the fourth motor 19 is connected to a drive belt 191 to drive the side support roller set 16. When the cable is placed on the side support roller set 16, the cable can be driven to rotate synchronously through friction; Pressing wheels 151 are arranged on both sides of the inkjet printing unit 15, and the inkjet printing unit 15 is configured to be slidable in the horizontal direction and the vertical direction. Refer to Figure 9 As shown, an installation table surface 12 is provided on the back of the inkjet printing unit 15. A horizontal module 13 is provided on the installation table surface 12, and the frame where the inkjet printing unit 15 is located is configured on the horizontal module 13. A vertical module 14 is provided on the frame body, and the inkjet printing unit 15 can slide up and down under the drive of the vertical module 14. The inkjet printing unit 15 has two functions. One is to draw a marking line with a spacing of 200 mm in the center of the cable insulation layer. After the cable is statically placed at high temperature, the change of the marking line is measured to obtain the axial shrinkage rate of the insulation layer. The other is to inkjet print the cable to distinguish test items, which is convenient for tracking subsequent test data.

[0037] Continuing to refer to Figure 8 As shown, a manipulator 6 is further included. The manipulator 6 is installed at the front end of a three-axis robotic arm 5, and the three-axis robotic arm 5 is configured on a transverse movement module 4; The structure of the manipulator 6 refers to Figure 10 As shown, it includes a movable jaw 61 driven by a clamping cylinder 63 and a fixed jaw 62 fixedly arranged. A distance measuring sensor is provided at the bottom of the movable jaw 61 for measuring the distance between the two jaws. When the cable is clamped, the diameter of the cable can be obtained therefrom.

[0038] The inkjet printing and marking station 1 and the stripping station 3 are arranged in sequence along the direction of the transverse movement module 4, so that the manipulator 6 can load and unload the inkjet printing and marking station 1 and the stripping station 3; in addition, refer to Figure 8 As shown, a material bin 31 is provided at the bottom of the stripping station 3.

[0039] A temporary storage bracket 11 is arranged in the area between the inkjet printing and marking station 1 and the stripping station 3, and a pre-storage bracket 2 is arranged on the side of the stripping station 3 away from the inkjet printing and marking station 1. The designs 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 operator first loads the cable onto the inkjet printing and marking station 1 for marking work. After the marking work is completed, it is then 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 realize a fully automated loading and unloading process.
