Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping, in particular to an industrial robot automatic stripping device. Background Art

[0002] An industrial robot is a type of robot used in industrial processes. An industrial robot is a tool that can be equipped to automatically handle or process objects and can perform multi-station operations. The industrial robot itself requires cables for circuit line connection. Therefore, cables are an indispensable configuration for the operation of industrial robots. Among them, highly flexible cables are a type of cable used in circuit connections of industrial robots. Highly flexible cables are composed of one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. The cables can be recycled after use, but during recycling, the insulating protective layer needs to be stripped from the metal conductor to achieve classified recycling of the plastic protective layer and the metal conductor. A wire stripping machine is a machine that strips the plastic sheath from the metal core of wires.

[0003] When stripping the wires, the existing wire stripping machines will cut the cables to facilitate the subsequent cable stripping. However, since the cables are composed of multiple protective layers, the one-way incision used during the cutting is not conducive to all-round stripping of the cable skin during the subsequent stripping. The cable skin's own resilience and adhesive force will cause the knife to stick to it during stripping, and the stripping depth of the cable is not good, which is not conducive to secondary stripping, making it easy for the inner layer of the cable skin to be missed.

[0004] Therefore, those skilled in the art provide an industrial robot automatic wire stripping device to solve the problems raised in the above background technology. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Specifically, through the setting of the squeezing rollers 6, two groups of squeezing rollers 6 are set in parallel up and down, and the upper and lower groups have the same structure. The motor 7 is used to drive the gear shaft 5 to rotate, and the gear shaft 5 drives the squeezing rollers 6 to rotate. The two groups of squeezing rollers 6 rotate relatively, squeezing the cable body 12 from one side of the squeezing roller 6 to the other side.

[0030] A peeling seat 8 is installed on the outer side of the squeezing roller 6, a perforation 801 is arranged inside the peeling seat 8, and a stripping knife 802 is installed on the inner wall of the perforation 801, a back seat 803 is installed on one side surface of the peeling seat 8, and an inner roller 804 is movably installed on the surface of the back seat 803, one end of the inner roller 804 is connected to a gear set 805, and a motor 2 806 is connected on the center line of the gear set 805, an outer roller 807 is installed on the outer side of the inner roller 804 in parallel, and a motor 3 808 is connected to one end of the outer roller 807, and a push ring 809 is arranged on the back side of the perforation 801, and the stripping knife 802 is distributed in a cross shape with respect to the symmetrical center line of the perforation 801, and the setting position of the stripping knife 802 is staggered with the setting positions of the inner roller 804 and the outer roller 807;

[0031] Specifically, after the cable body 12 passes through the squeezing roller 6, it passes through the perforation 801 set on the surface of the stripping seat 8. The stripping knives 802 are cross-shapedly arranged on the inner wall of the perforation 801. The four groups of stripping knives 802 will perform cross-shaped cutting on the surface of the cable body 12, so that the surface of the cable body 12 is cut in four different directions. When the cable skin is cut by the stripping knives 802, the elastic force of the cable skin itself is cut, and the tension force on the rubber surface is disconnected. The elastic force of the rubber itself will cause the rubber to open, and the roller 11 is driven by the driving device to tighten the cable. The copper core 13 inside the main body 12 is continuously wound up, pulling the cable main body 12. Thus, in conjunction with the use of the push ring 809, after the cable is cut, when the cable is pulled and moved, the push ring 809 will push the cut rubber outwards, and the inner roller 804 and the outer roller 807 located above, use motor two 806 and motor three 808 to drive the inner roller 804 and the outer roller 807 to rotate, and the inner roller 804 and the outer roller 807 rotate in opposite directions, squeezing the rubber out from between the inner roller 804 and the outer roller 807, so that the rubber is completely separated from the cable main body 12.

[0032] A scraper 9 is installed on one side of the stripping seat 8, and a blade 10 is provided on the surface of the scraper 9, a winding roller 11 is installed obliquely below the scraper 9, a guide roller 4 is installed on the inner side of the positioning seat 3, and a cable body 12 is inserted between the guide rollers 4, a copper core 13 is provided at the inner center of the cable body 12, a fixing seat 301 is fixedly installed between the positioning seat 3 and the squeezing roller 6, and a stabilizing hole seat 302 is provided inside the surface of the fixing seat 301, and the guide roller 4, the fixing seat 301, the squeezing roller 6, the stripping seat 8 and the blade 10 on the surface of the scraper 9 are all located in the same straight line;

[0033] Specifically, through the setting of the guide roller 4, the surface design of the guide roller 4 is concave inward, so that the cable body 12 can pass through the double-row guide rollers 4. By rotating the guide roller 4, while completing the orientation of the cable body 12, the friction force is used to push the cable body 12 forward, pass through the stable hole seat 302 set on the surface of the fixed seat 301, and then pass between the squeezing rollers 6, pass through the blade 10 on the scraper 9, and finally, be wound on the winding roller 11, thereby completing the installation between the cable body 12 and the wire stripping machine base 1.

[0034] One end of the scraper 9 is connected to a connecting arm 14, and the end of the connecting arm 14 away from the scraper 9 is movably connected to a tension piece 15, a rotating shaft seat 17 is installed on the inner side of the middle part of the tension piece 15, and the lower ends of the tension piece 15 and the rotating shaft seat 17 are connected to a rotating shaft seat 19, a slide seat 20 is movably installed on one side of the rotating shaft seat 19, and a slide rail 21 is slidably installed below the slide seat 20, a connecting shaft 16 for movement is provided between the tension piece 15 and the connecting arm 14, the tension piece 15 and the rotating shaft seat 17 are rotatably connected, and a motor 18 is fixedly installed on one side of the middle part of the tension piece 15;

[0035] Specifically, the scraper 9 is set so that after the rubber on the surface of the cable body 12 is stripped by the stripping seat 8, it passes through the blade 10 and uses the scraper 9 to push and scrape the residual rubber on the inner layer of the cable to reduce the residual rubber on the surface of the copper core 13. At the same time, the tension piece 15 is used to pull the copper core 13, thereby adjusting the tension setting of the entire cable body 12. The motor 18 drives the tension piece 15 to rotate, and in conjunction with the rotating structure between the tension piece 15 and the rotating shaft seat 17, the tension piece 15 rotates clockwise. The upper end of the tension piece 15 uses the setting of the connecting shaft 16 to pull the connecting arm 14 outward. When the tension piece 15 is moving, the lower end of the tension piece 15 slides along the slide rail 21 through the setting of the rotating shaft seat 19 and the slide seat 20. In this way, the tension piece 15 drives the connecting arm 14 to tighten the copper core 13, thereby affecting the cable body 12, thereby realizing the tension adjustment of the cable body 12.

[0036] Working principle: First, the cable body 12 is passed between the double-row guide rollers 4. The cable body 12 is oriented by the rotation of the guide rollers 4. The cable body 12 is pushed forward by the friction force and passes through the stable hole seat 302 set on the surface of the fixed seat 301. Then, it passes between the squeezing rollers 6, passes through the blade 10 on the scraper 9, and finally, it is wound on the winding roller 11. Secondly, it passes through the blade 10 and uses the scraper 9 to push and scrape the rubber remaining on the inner layer of the cable to reduce the rubber residue on the surface of the copper core 13. At the same time, the tension piece 15 is used to pull The motor 18 drives the tension piece 15 to rotate, and the tension piece 15 rotates clockwise in coordination with the rotation structure between the tension piece 15 and the rotating shaft seat 17. The upper end of the tension piece 15 uses the setting of the connecting shaft 16 to pull the connecting arm 14 outward. When the tension piece 15 is in motion, the lower end of the tension piece 15 slides along the slide rail 21 through the setting of the rotating shaft seat 19 and the slide seat 20. In this way, the tension piece 15 drives the connecting arm 14 to tighten the copper core 13, thereby affecting the cable body 1 2, thereby realizing the tension adjustment of the cable body 12, and then, after the cable body 12 passes through the squeezing roller 6, it passes through the perforation 801 set on the surface of the stripping seat 8, and the stripping knives 802 are cross-shapedly arranged on the inner wall of the perforation 801. The four groups of stripping knives 802 will perform cross-shaped cutting on the surface of the cable body 12, so that the surface of the cable body 12 can be cut in four different directions. When the cable skin is cut by the stripping knives 802, the elastic force of the cable skin itself is cut, and the tension force on the rubber surface is disconnected. The elastic force of the rubber itself will cause the rubber to open, and the roller 11 is driven by the stripping knife 802. Driven by the equipment, the copper core 13 inside the cable body 12 is continuously wound up, which will pull the cable body 12. In this way, with the use of the push ring 809, after the cable is cut, when the cable is pulled and moved, the push ring 809 will push the cut rubber outward, and the inner roller 804 and the outer roller 807 located above use motor two 806 and motor three 808 to drive the inner roller 804 and the outer roller 807 to rotate. The inner roller 804 and the outer roller 807 rotate in opposite directions, squeezing the rubber out from between the inner roller 804 and the outer roller 807, so that the rubber is completely separated from the cable body 12.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
