Description

Technical Field

[0001] The present invention relates to the technical field of cable cutting machine devices, in particular to a high-precision cable cutting machine that prevents optical cables from being damaged. Background Art

[0002] A cable cutter is a device for cutting optical cables. It can also reel up the optical cables, which not only arranges the cut cables neatly but also saves space. A cable cutter generally cuts and winds large rolls of optical cables into reels of different diameters. During the transportation of large rolls of optical cables, the optical cables may be damaged or have hidden injuries such as internal fractures. These injuries are difficult to detect through manual observation. Current cable cutters do not have an optical cable detection function, and unqualified optical cables may be mistakenly shipped as qualified products. Therefore, a high-precision cable cutter that prevents optical cable damage is designed to solve the above problems.

[0003] For example, the document with publication number CN212953522U proposes a high-precision adjustable cable cutting machine, which includes a main box and a PLC touch screen operation panel. A motor is provided on the left side of the front side of the main box, and the output end of the motor is fixedly connected to a turntable. The front and rear sides of the turntable are fixedly connected to T-shaped discs. A support frame is fixedly connected to the right side of the front side of the main box. A square frame is rotatably connected between the upper and lower support frames. Slideways are provided on the inner walls of the front and rear sides of the square frame. A two-way hydraulic rod is fixedly installed on the inner wall of each slideway, and sliders are fixedly connected to the upper and lower ends of the two-way hydraulic rod. This device is easy to operate and adjust, and can accurately measure and cut the length of optical cables.

[0004] The above-mentioned high-precision adjustable cable cutting machine has the following defects: the above-mentioned high-precision adjustable cable cutting machine does not have the function of detecting optical cables. Generally, cable cutting machines cut and coil large rolls of optical cables into optical cable coils of different diameters. However, large rolls of optical cables need to be moved or transported over long distances before cutting. If protective measures are not in place, the optical cables may be easily damaged or broken, or even the surface of the optical cables may be intact, but the inside may be broken. Generally, such conditions cannot be discovered in time by operators, and unqualified optical cables may be mistakenly shipped as qualified products, which not only affects the pass rate of the entire batch of products, but also has a negative impact on manufacturers.

[0005] In response to the above problems, a high-precision cable cutting machine that prevents optical cable damage is proposed. Summary of the Invention

[0033] 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.

[0034] In order to solve the technical problem that the cable cutting machine cannot detect whether the optical cable is damaged during the cutting and winding process, such as Figure 1-Figure 5 As shown, the following preferred technical solutions are provided:

[0035] A high-precision cable cutting machine for preventing optical cable damage comprises a base 1, a left-right moving component 2 arranged on the base 1, a front-back moving component 3 arranged on the top surface of the left-right moving component 2, a lifting component 4 fixedly arranged on the top surface of the front-back moving component 3, an active wire-releasing component 5 slidingly arranged on the lifting component 4, and the coordinated arrangement of the left-right moving component 2, the front-back moving component 3 and the lifting component 4 enables the active wire-releasing component 5 to be flexibly adjusted in position in both the horizontal and vertical directions, so that the active wire-releasing component 5 can be adjusted to a suitable position for wire-releasing, keeping the front and rear sections of the optical cable in the same plane as much as possible during the wire-releasing process. Such an arrangement reduces the wear of the optical cable caused by the equipment during the cable cutting process, and to a certain extent The yield rate of the product can be improved in terms of degree. A tensioning component 6 is fixedly provided on the base 1. The setting of the tensioning component 6 can adjust the tension on the optical cable during the cutting process of the optical cable, so that the force on the optical cable during the entire cutting and winding process is stable and uniform, and the phenomenon of the optical cable being stretched or even broken due to excessive tension is minimized as much as possible. A compression meter component 7 is fixedly provided on the side wall of the base 1. Through the compression effect of the compression meter component 7, the optical cable is further limited, so that the optical cable will not have too much position deviation and shaking during the cutting and winding process, which is beneficial to reduce the wear of the optical cable on the equipment. At the same time, when the set length of the optical cable has been wound up, the control system will control the compression meter component 7 to stop rotating and firmly press the optical cable. , so that the optical cable will not shrink, so that the compression meter component 7 can maintain an accurate metering effect. A limited cutting component 8 and an inkjet component 9 are provided on the side wall of the base 1, and the inkjet component 9 is fixedly arranged on one side of the limited cutting component 8. A telescopic guide wheel 10 is telescopically provided on the side wall of the base 1. The telescopic guide wheel 10 can adjust the position of the optical cable through the reciprocating motion of the telescope, so that the optical cable can be rolled up evenly, and there will be no phenomenon that the optical cables are concentrated in one piece after the winding is completed. A winding component 20 is also rotatably provided on the side wall of the base 1, and a detection component 30 is movably provided on the winding component 20. When the optical cable is cut and wound, one end of the optical cable is connected to the detection component 30, and the optical cable is pre-fixed on the winding component 20, at this time, the equipment is started to operate, and the detection component 30 starts to detect whether the connected optical cable is damaged. If the optical cable is found to be intact after detection by the detection component 30, the equipment will normally cut the optical cable through the limit cutting component 8 and reel the optical cable through the reeling component 20. If the detection component 30 detects that the optical cable is damaged, but the distance is greater than the set reeling length, the control system will not take any action, and the equipment will still cut and reel normally. When the detection component 30 detects that the optical cable is damaged and the distance is less than the set reeling length, the detection component 30 will feed back a signal to the control system, and the control system will calculate the distance to the damaged part of the optical cable by pressing the meter-counting component 7. When the pressing meter-counting component 7 just presses over the damaged part of the optical cable,The compression meter component 7 immediately feeds back a signal to the control system, which in turn controls the equipment to stop paying out and reeling in the cable, and controls the compression meter component 7 to stop rotating, firmly pressing the optical cable to prevent it from retracting. At the same time, the control system controls the limit cutting component 8 to cut the damaged part of the cable, and the inkjet component 9 simultaneously sprays a bright contrasting color pigment on the damaged part of the cable as a mark to distinguish it from qualified products. By repeating the above operations, continuous inspection of the optical cable can be achieved.

[0036] The winding assembly 20 includes a rotating shaft 203 rotatably mounted on the side wall of the base 1 and a winding drum 201 fixedly sleeved on the outer wall of the rotating shaft 203. A plurality of diameter-adjusting assemblies 202 are threadedly connected to the winding drum 201. When cutting and winding the optical cable, one end of the optical cable is first pre-fixed on the diameter-adjusting assembly 202. At this time, the starting device drives the winding drum 201 to rotate together through the rotating shaft 203, and the diameter-adjusting assembly 202 also rotates with the winding drum 201, thereby realizing the winding of the optical cable. At the same time, by adjusting the extended length of the diameter-adjusting assembly 202, the diameter of the cable coil can be adjusted. Such a setting can meet the requirements of various winding diameters and is highly practical. A long slide groove 206 is provided on the side wall of the winding disk 201, and the slide plate 301 is embedded and slidably set in the inner cavity of the long slide groove 206. A circular baffle 204 is also slidably sleeved on the outer wall of the outer periphery of the rotating shaft 203, and the output end of the rotating shaft 203 is also threadedly connected with a fastener 205, and the fastener 205 is set on the outside of the circular baffle 204. The setting of the circular baffle 204 facilitates the winding of the optical cable and prevents the optical cable from falling during the winding process, causing damage to the optical cable or even damage to the equipment. The circular baffle 204 can be limited by the fastener 205, so that the circular baffle 204 will not have a large position deviation on the rotating shaft 203, thereby maintaining the stability of the cable winding.

[0037] The diameter adjustment component 202 includes an adjusting column 2021 that is threadedly connected to the winding drum 201 and a winding rod 2022 that is rotatably sleeved on the adjusting column 2021. By rotating the adjusting column 2021 to adjust the depth of the adjusting column 2021 on the winding drum 201, the adjustment of different winding diameters can be achieved. The operation is simple and convenient. The winding rod 2022 not only pre-fixes one end of the optical cable, but also can reel the optical cable when the equipment is running. The other end of the winding rod 2022 is fixedly installed with a round ball 2023, which has a certain shielding effect on the optical cable to prevent the optical cable from falling to the ground.

[0038] When cutting and winding the large roll of optical cable on the active pay-off assembly 5, after passing the optical cable through the tensioning assembly 6, the compacting meter assembly 7, the limit cutting assembly 8 and the telescopic guide wheel 10, the end of the optical cable that has passed through is pre-fixed on the winding assembly 20, so that the optical cable can be wound up when the equipment is started. Then the end of the optical cable that has passed through is connected to the detection assembly 30 to detect the optical cable that needs to be cut. The above-mentioned arrangement can simultaneously detect the optical cable during the process of cutting and winding the optical cable, detect whether the optical cable has hidden damage and detect the distance of the hidden damage to the optical cable, so that the staff can find unqualified products in time and collect and process the unqualified products, reducing the risk of unqualified products entering the market and saving money to a certain extent.

[0039] In order to solve the technical problems that the damaged parts of the optical cable are not marked after cutting, which makes it difficult for operators to find, collect and process them uniformly and is easy to be confused with qualified products, such as Figure 1 and Figure 6-Figure 8 As shown, the following preferred technical solutions are provided:

[0040] The left and right moving assembly 2 includes several slides A21 fixedly mounted on the top surface of the base 1 and a load-bearing plate A22 slidably mounted on the slides A21. An electric telescopic column A23 is fixedly arranged on the top surface of the base 1, and the extended end of the electric telescopic column A23 is fixedly connected to the side wall of the load-bearing plate A22. By adjusting the telescopic difference length of the electric telescopic column A23, the load-bearing plate A22 can be driven to slide on the slide A21 to achieve left and right position adjustment.

[0041] The forward and backward moving component 3 includes a slide B31 fixedly mounted on the top surface of the load-bearing plate A22 and a load-bearing plate B32 movably mounted on the slide B31. An electric telescopic column B33 is fixedly mounted on the top surface of the load-bearing plate A22, and the extended end of the electric telescopic column B33 is fixedly connected to the side wall of the load-bearing plate B32. When the electric telescopic column B33 is started and the extension length of the electric telescopic column B33 is adjusted, the electric telescopic column B33 will slide on the slide B31 with the load-bearing plate B32, so that the forward and backward position can be adjusted.

[0042] The top of the electric strut 43 is fixedly connected to the bottom surface of one end of the support plate 42, and the upper end of the electric strut 43 is fixedly connected to the bottom surface of one end of the support plate 42. By adjusting the height of the electric strut 43, the height of the support plate 42 can be adjusted, and then the height of the active pay-off assembly 5 can be adjusted. Then, through the auxiliary adjustment of the front and rear moving assembly 3 and the left and right moving assembly 2, the active pay-off assembly 5 can be adjusted in both horizontal and vertical directions, so that the active pay-off assembly 5 is in a suitable pay-off position. Due to the large overall weight of the equipment, manually moving the equipment to adjust the pay-off position of the active pay-off assembly 5 not only wastes manpower, but also easily causes personal injury and is inconvenient to operate. The position adjustment of the active pay-off assembly 5 can be achieved through the above-mentioned setting, which not only saves manpower but is also simple and convenient.

[0043] The active pay-off assembly 5 includes a fixing frame 51 fixedly mounted on the top surface of the support plate 42 and a pay-off motor 52 fixedly mounted on the fixing frame 51. The fixing frame 51 supports and fixes the pay-off motor 52, so that the pay-off motor 52 can operate stably without excessive shaking. The output end of the pay-off motor 52 is fixedly connected to a long shaft 53, and a detachable pay-off roller 54 is fixedly provided on the outer peripheral wall of the long shaft 53. The pay-off roller 54 on the long shaft 53 is driven to rotate by the rotation of the pay-off motor 52, thereby realizing active pay-off of the optical cable. The pay-off roller 54 is detachable and is easy to replace when the optical cable pay-off is completed.

[0044] The tensioning assembly 6 includes a hollow frame 61 fixedly mounted on the top surface of the base 1 and a fixed rotating wheel 62 rotatably arranged on the side wall of the upper end of the hollow frame 61. A movable rotating wheel 63 is also slidably arranged on the side wall of the hollow frame 61. The optical cable passes through the fixed rotating wheel 62 and the movable rotating wheel 63 and is transmitted on the fixed rotating wheel 62 and the movable rotating wheel 63. When there is a deviation between the front end pay-out speed and the rear end winding speed of the cable cutting machine or due to other factors, the optical cable is subjected to uneven force during the cutting and winding process, the movable rotating wheel 63 will slide up and down on the hollow frame 61 under the action of the force to unload the force, so that the tension of the optical cable during the entire cutting and winding process is stable and uniform, avoiding the optical cable being broken or stretched due to uneven force, and the fixed rotating wheel 62 and the movable rotating wheel 63 are in an aligned state in the vertical direction. Such an arrangement can reduce the wear of the equipment on the optical cable and is conducive to ensuring the quality of the product.

[0045] The meter pressing assembly 7 includes a plurality of curved brackets 71 fixedly mounted on the base 1 and an electric cylinder A72 fixedly mounted on the curved bracket 71. A meter pressing wheel 73 is fixedly mounted on the extended end of the electric cylinder A72. A roller 74 is provided below the meter pressing wheel 73 for rolling engagement. The roller 74 is rotatably arranged on the side wall of the base 1. A wire groove of a certain depth is provided on the outer wall of the roller 74. The optical cable passes through the gap in the wire groove and passes through the meter pressing wheel 73 and the roller 74. When the optical cable is cut and wound, the wire groove The optical cable will be transmitted, and the meter-counting pinch wheel 73 and the roller 74 will start to rotate at the same time. At this time, the meter-counting pinch wheel 73 starts to calculate the length. When the length calculated by the meter-counting pinch wheel 73 reaches the set optical cable winding length, the meter-counting pinch wheel 73 will feed back a signal to the control system. The control system controls the meter-counting pinch wheel 73 to hold and rotate. At the same time, the electric cylinder A72 applies pressure downward. The meter-counting pinch wheel 73 firmly presses the optical cable so that the optical cable will not retract, which is beneficial to improving the accuracy of the equipment in cutting the optical cable.

[0046] The limiting cutting assembly 8 includes a U-shaped frame 81 and an electric cylinder B82 fixedly installed on the U-shaped frame 81. A cutter 83 is fixedly installed at the lower end of the electric cylinder B82. When the optical cable needs to be cut, the electric cylinder B82 will move downward and drive the cutter 83 to move downward to cut the optical cable. A limiting ring 84 is fixedly provided below the cutter 83. The optical cable will pass through the inner cavity of the limiting ring 84 during the cutting and winding process to prevent the optical cable from being significantly offset during the cutting and winding process, resulting in incomplete cutting of the optical cable by the cutter 83 and greater damage to the optical cable.

[0047] The inkjet assembly 9 includes an inkjet device body 91 fixedly installed on one side of the cutter 83 and an L-shaped bracket 92 fixedly installed on the top surface of the inkjet device body 91. The other end of the L-shaped bracket 92 is fixedly installed with a detachable inkjet head 93. When the optical cable is detected to be damaged, the control system will control the equipment to cut the damaged optical cable. At the same time, the inkjet device body 91 controls the inkjet head 93 to spray ink on the damaged part of the optical cable. The color of the sprayed ink is preferably a color that contrasts significantly with the color of the optical cable, which is convenient for subsequent operators to find. At the same time, it also prevents it from being mixed with qualified products for shipment, resulting in a decline in product quality.

[0048] When the detection component 30 detects that the optical cable is damaged and calculates the damage distance, the detection component 30 will feed back the data signal to the control system. When the control system determines that the damage distance is less than the preset winding length, it calculates the length through the compression meter component 7. When the compression meter component 7 reaches the damage position, the control system controls the compression meter component 7 to stop running and firmly presses the optical cable to prevent the optical cable from retracting, resulting in inaccurate judgment of the damage position. At this time, the control system controls the limiting cutting component 8 to cut the damaged part of the optical cable, and controls the inkjet component 9 to spray ink on the damaged part of the optical cable. Through the above settings, when the detection component 30 detects that the optical cable is damaged, it can calculate the damage distance in time and cut the damaged part of the optical cable, which can prevent unqualified products from entering the market. At the same time, the damaged part of the optical cable is inkjet marked, which is convenient for subsequent staff to find, collect and process in a unified manner, and avoid being mixed with qualified products and mistakenly shipped as qualified products.

[0049] In order to solve the technical problem that when adjusting the winding diameter, one end of the optical cable is bent when connected to the detection instrument, which may easily cause damage to the optical cable and the detection interface. Figure 5 and Figure 9-10 As shown, the following preferred technical solutions are provided:

[0050] The detection assembly 30 includes a slide 301 slidably mounted on the reel assembly 20 and an optical time domain reflectometer 302 rotatably mounted on the slide 301. When the diameter of the reeled optical cable coil changes, the slide 301 is moved on the reel assembly 20 to drive the optical time domain reflectometer 302 to slide. The optical time domain reflectometer 302 is adjusted to a suitable position according to the diameter of the reeled optical cable coil. Then, one end of the optical cable is connected to the optical time domain reflectometer 302 for detection. This arrangement reduces the degree of bending at the access end of the optical cable, reduces damage to the optical cable to a certain extent, and improves the flexibility of detection. The slide plate 301 is also provided with a stepless positioning component 303, and the stepless positioning component 303 is arranged closely against the optical time domain reflectometer 302. After the stepless positioning component 303 is pinched, the stepless positioning component 303 loses its ability to position the optical time domain reflectometer 302. At this time, the optical time domain reflectometer 302 is rotated to adjust the interface to a position suitable for accessing the optical cable. After the force of pinching the stepless positioning component 303 is released, the stepless positioning component 303 regains its ability to position the optical time domain reflectometer 302. Through the above operation, the stepless positioning of the optical time domain reflectometer 302 can be achieved, and the interface position can be adjusted to facilitate the access of the optical cable.

[0051] The optical time domain reflectometer 302 includes an instrument body 3021 that is embedded and rotatably mounted on the slide 301, and an optical cable interface 3022 that is fixedly mounted on the side wall of the instrument body 3021. The optical time domain reflectometer 302 is referred to as an OTDR. The optical cable to be cut and reeled is connected to the optical cable interface 3022. The instrument body 3021 is used to inspect the optical cable to detect whether the optical cable is damaged and the distance to the damage. The detected signal is fed back to the control system, which then makes subsequent control decisions.

[0052] The stepless positioning assembly 303 includes a pair of fixed columns 3031 fixed on the slide 301 and positioning pieces 3032 movably mounted on the outer wall of the fixed columns 3031. The positioning pieces 3032 are all set close to the instrument body 3021. The positioning pieces 3032 are elastically connected by springs 3033. When the instrument body 3021 needs to be rotated to adjust its position, pressure is applied to the positioning pieces 3032 inwardly, and the ends of the positioning pieces 3032 near the instrument body 3021 will move to the sides. If the instrument body 3021 is rotated, the positioning ability of the instrument body 3021 will be lost. At this time, the spring 3033 is in a compressed state. When the position of the instrument body 3021 is adjusted, when the pressure applied to the positioning piece 3032 is released, under the elastic force of the spring 3033, the end of the positioning piece 3032 close to the instrument body 3021 returns to its original position to clamp the instrument body 3021. It will be clamped whether it is rotated clockwise or counterclockwise. Through the above operation, the infinite positioning of the instrument body 3021 can be achieved.

[0053] When the optical cable is cut and reeled on the equipment, one end of the optical cable needs to be connected to the optical cable interface 3022, which is convenient for subsequent detection of the optical cable. After the reeling assembly 20 adjusts the different reel diameters, the optical cable will be bent to a certain extent when it is connected to the optical cable interface 3022. At this time, after the optical cable interface 3022 is adjusted to a suitable position by rotating the instrument body 3021, the instrument body 3021 is positioned by the stepless positioning assembly 303, and then the optical cable is connected to the optical cable interface 3022. Through the above-mentioned arrangement, the instrument body 3021 can adjust the optical cable interface 3022 to a suitable access position by rotation, reducing the bending angle of the optical cable, which not only protects the optical cable and the optical cable interface 3022, but also increases the flexibility of optical cable detection. At the same time, the stepless positioning assembly 303 is positioned to obtain sufficient stability, so that during the optical cable detection process, the instrument body 3021 will not be unstable and rotated, resulting in damage to the optical cable interface 3022. Such an arrangement can adapt to optical cable coils with different reel diameters, and has good flexibility and strong practicality.
