Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a flexible tensile-resistant robot cable and a production process. Background Art

[0002] With the rapid development of science and technology today, robots are widely used in many industries. Robots need to walk, turn, move, and perform other actions during operation. Robot cables need to move or bend continuously in coordination with the robot's actions. Therefore, robot cables need to have good bending performance, tensile performance, and torsional resistance, so that the cables can still maintain stable power and signal transmission under conditions of continuous movement, twisting, or bending.

[0003] Currently, industrial robot cables generally use tinned copper conductors and aramid reinforcement structures, mainly using steel wire braids to improve mechanical properties and have good tensile and torsional properties. However, when the robot performs joint bending activities, the installed steel wire braids will affect the robot's movement, requiring the robot to use greater force to bend the steel wire braids. Moreover, long-term bending work can easily lead to a reduction in the service life of the cable.

[0004] Therefore, it is necessary to provide a flexible tensile-resistant robot cable and a production process to solve the above technical problems. Summary of the Invention

[0011] Step 5: Preparation of the tensile layer: another set of extrusion equipment is used to extrude the raw materials onto the outside of the insulating layer to form the tensile layer. During the preparation of the tensile layer, spiral blocks that match the spiral grooves will be formed on the inner side of the tensile layer, and two sets of symmetrical and intersecting double spiral grooves will be formed on the outer side of the tensile layer;

[0012] Step six: preparing the sheath layer, extruding the raw material on the outside of the tensile layer through an extruder to form a sheath layer, and forming a cross-helical block that matches the double helical groove on the inside of the sheath layer;

[0013] The extrusion equipment in step four includes a base installed on the ground, support blocks are installed at both ends of the top of the base, a fixing seat with round holes passing through both ends is installed on the top of the support block, a cable limiting mechanism is installed on the inner side of the fixing seat, an extrusion transport pipe is installed on the inner side of the fixing seat, and a production mechanism with a spiral groove is provided inside the extrusion transport pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a spiral groove on the outer side of the insulating layer, so that a spiral block that matches the size of the spiral groove is formed on the inner side of the tensile layer, thereby forming a mutually obstructing structure between the insulating layer and the tensile layer. During the stretching process, the insulating layer and the tensile layer can obstruct each other, thereby greatly improving the tensile performance between the insulating layer and the tensile layer. In addition, double spiral grooves that intersect with each other are formed on the outer side of the tensile layer, so that cross spiral blocks that match the size of the double spiral groove are formed on the inner side of the extruded sheath layer. This allows the sheath layer to quickly recover after bending, thereby improving the bending performance. In addition, the cross spiral blocks formed between the tensile layer and the sheath layer enable the tensile layer to also have a certain bending recovery ability, thereby reducing the damage to the tensile layer caused by bending.

[0021] The downward movement of the adjusting rod of the present invention squeezes the oil in the communicating hole into the annular channel. At this time, the oil in the annular channel enters the transport hole, driving the piston rod to move toward the center of the fixing seat, thereby causing the movable block to move toward the center of the fixing seat, so that the rotatably arranged rolling ball block presses against the outer wall of the cable shielding layer, thereby limiting the position of the cable shielding layer at the center of the fixing seat and preventing the rotation of the rolling ball block from affecting the transport of the cable shielding layer.

[0022] When the insulating layer in the molten state of the present invention is transported to the interior of the production mechanism, the rotation of the ring part can be controlled to drive the protrusion to open a spiral groove on the outer wall of the insulating layer in the molten state. After the insulating layer with the spiral groove passes through the fixed seat on the other side, it enters the next group of extrusion equipment that can open a double spiral groove. The internal dimensions of this extrusion equipment are different from those of the previous group, and two groups of production mechanisms will be set up, and the rotation directions of the two groups of ring parts are opposite. At this time, during the transportation of the insulating layer, the material can be extruded into the outside of the insulating layer by entering the extrusion mold to form a tensile layer, and a spiral block adapted to the spiral groove opened on the outside of the insulating layer will be formed on the inner side of the tensile layer, and the rotation of the two groups of ring parts will drive the protrusion to open a double spiral groove on the outside of the tensile layer.

The following describes an embodiment of the present invention based on its overall structure.

[0033] See also Figure 1-7 , a production process of a flexible tensile-resistant robot cable, comprising the following production steps:

[0034] Step 1: Conductor pretreatment: The copper-magnesium alloy wire is twisted in a regular manner using a stranding machine, and TPU modified solution is sprayed in the twisted gap to form a sub-cable;

[0035] Step 2: preparing the inner core 1, using a stranding machine to strand multiple wound sub-cables on the outside of the central sub-cable to form the inner core 1;

[0036] Step 3: Preparation of shielding layer 2: Extruding the raw materials onto the outer side of the inner core by an extruder to form shielding layer 2;

[0037] Step 4: Preparation of the insulating layer 3: Extruding the raw material onto the outer side of the shielding layer 2 by an extrusion device to form the insulating layer 3. During the preparation of the insulating layer 3, a spiral groove is formed on the outer side of the insulating layer 3.

[0038] Step 5: Preparation of the tensile layer 4: The raw material is extruded onto the outer side of the insulating layer 3 by another set of extrusion equipment to form the tensile layer 4. During the preparation of the tensile layer 4, spiral blocks 5 that match the spiral grooves are formed on the inner side of the tensile layer 4, and two sets of symmetrical and mutually intersecting double spiral grooves are formed on the outer side of the tensile layer 4.

[0039] Step six; the sheath layer 6 is prepared by extruding the raw material on the outside of the tensile layer 4 by an extruder to form a sheath layer 6, and the inner side of the sheath layer 6 will form a cross spiral block 7 that adapts to the double helical groove;

[0040] The prepared cable has a rated voltage of 300V, a rated temperature of -40℃~125℃, a withstand voltage of 1.5kV / 5min, a minimum bending radius of 5×D in static state and 10×D in dynamic state, a maximum speed of 5m / s, and a maximum tensile strength of 3800 to 4000MPa. The tensile layer is made of Kevlar fiber material, which has good tensile properties and can be used in conjunction with the spiral groove. The sheath layer is made of an elastomer material with good reset elasticity, which allows the cable to quickly reset when bent.

[0041] By opening a spiral groove on the outside of the insulating layer 3, a spiral block 5 that fits the size of the spiral groove is formed on the inside of the tensile layer 4, so that a mutually obstructing structure is formed between the insulating layer 3 and the tensile layer 4, which can obstruct each other during the stretching process, greatly improving the tensile performance between the insulating layer 3 and the tensile layer 4, and mutually intersecting double spiral grooves are formed on the outside of the tensile layer 4, so that a cross spiral block 7 that fits the size of the double spiral groove is formed on the inside of the extruded sheath layer 6, so that the sheath layer 6 can recover quickly after bending, and has better bending performance. In addition, the cross spiral block 7 formed between the tensile layer 4 and the sheath layer 6 enables the tensile layer 4 to also have a certain bending recovery ability, reducing the damage to the tensile layer 4 caused by bending.

[0042] The extrusion equipment in step four includes a base 8 installed on the ground, support blocks 9 are installed at both ends of the top of the base 8, a fixing seat 10 with round holes passing through both ends is installed on the top of the support block 9, a cable limiting mechanism 11 is installed on the inner side of the fixing seat 10, an extrusion transport pipe is installed on the inner side of the fixing seat 10, and a production mechanism 12 with a spiral groove is provided inside the extrusion transport pipe.

[0043] like Figure 1-7As shown, the cable limiting mechanism 11 includes a circular channel 111 opened inside the fixing seat 10, and the top of the circular channel 111 is connected to a connecting hole 112 that passes through the top of the fixing seat 10, and an adjusting rod 113 extending to the outside of the fixing seat 10 is provided inside the connecting hole 112. A connecting seat 114 is installed at equal angles on the inner side of the fixing seat 10 through the circular hole, and a receiving groove 115 is opened on the side of the connecting seat 114 facing the center of the fixing seat 10. A movable block 116 is movably provided inside the receiving groove 115, and a rolling seat is installed on the side of the movable block 116 facing the center of the fixing seat 10. When it is necessary to extrude the outer side of the cable shielding layer 2 to produce the insulating layer 3, the material for preparing the insulating layer 3 is first placed in the blanking piece 19 for melting and heating, and then the shielding layer 2 in transport is passed through the inner side of the fixing seat 10. At this time, the staff presses the adjusting rod 113 downward to move downward, so that the multiple rolling seats can be adjusted to move toward the direction of the cable shielding layer 2, thereby squeezing and limiting it in the center position, which is convenient for subsequent extrusion work.

[0044] like Figure 1-7 As shown, the rolling seat includes a mounting seat 13 installed on the movable block 116 and connected to the center side of the fixed seat 10, and the mounting seat 13 is rotatably connected to the rolling ball block 14 inside. The circular channel 111 is connected to the side of the connecting seat 114 and is provided with a transportation hole 15 that penetrates into the interior of the accommodating groove 115. The interior of the transportation hole 15 is provided with a piston rod 16 fixed to the movable block 116 on the side of the circular channel 111. The downward movement of the adjusting rod 113 will squeeze the oil inside the communicating hole 112 into the interior of the circular channel 111. At this time, the oil inside the circular channel 111 will enter the interior of the transportation hole 15, driving the piston rod 16 to move toward the center position of the fixed seat 10, thereby making the movable block 116 move toward the center of the fixed seat 10, so that the rotating rolling ball block 14 is squeezed on the outer wall of the cable shielding layer 2, which can not only limit the position of the cable shielding layer 2 at the center of the fixed seat 10, but also the rotation of the rolling ball block 14 will not affect the transportation of the cable shielding layer 2.

[0045] like Figure 1-7 As shown, the extrusion transport pipeline includes a first pipeline 17 installed on the inner side of the right fixing seat 10, an extrusion die 18 is installed on the outer wall of one end of the first pipeline 17 facing the other group of fixing seats 10, a blanking part 19 is installed on the top of the extrusion die 18, and a second pipeline 20 is connected to the inner side of the other end of the extrusion die 18. The other end of the second pipeline 20 is connected to the third pipeline 21 fixed on the inner side of the left fixing seat 10. When the cable shielding layer 2 is transported to the inside of the extrusion die 18, the material is extruded on the outside of the shielding layer 2 for transportation through the extrusion technology in the prior art.

[0046] like Figure 1-7As shown, the production mechanism 12 includes a first annular groove 22 provided at one end of the third pipe 21 toward the second pipe 20, the first annular groove 22 is internally connected to a first annular plate 23 for rotation, one side of the first annular plate 23 is connected to an annular member 24 installed on the outside, and a protrusion 25 with a spiral groove is installed on the inner side of the annular member 24, and a second annular groove 26 is provided at one end of the second pipe 20 toward the third pipe 21, the second annular groove 26 is internally connected to a second annular block 27 for rotation, and the other end of the second annular block 27 is connected to one end of the annular member 24. When the insulating layer 3 in a molten state is transported to the inside of the production mechanism 12, the protrusion 25 can be driven to rotate in the molten state by controlling the rotation of the annular member 24. A spiral groove is opened on the outer wall of the insulating layer 3 in this state. After the insulating layer 3 with the spiral groove passes through the fixed seat 10 on the other side, it enters the next group of extrusion equipment that can open a double spiral groove. The internal size of this extrusion equipment is different from the previous group, and two groups of production mechanisms 12 will be set, and the rotation directions of the two groups of ring parts 24 are opposite. At this time, during the transportation of the insulating layer 3, it enters the extrusion mold 18 to extrude the material on the outside of the insulating layer 3 to form a tensile layer 4, and the inner side of the tensile layer 4 will form a spiral block 5 that is adapted to the spiral groove opened on the outside of the insulating layer 3, and the rotation of the two groups of ring parts 24 will drive the protrusion 25 to open a double spiral groove on the outside of the tensile layer 4.

[0047] like Figure 1-7 As shown, a support plate 28 is installed on the top of the base 8, a driving device 29 is installed on the top of the support plate 28, a gear 30 is installed on the driving device 29, and a gear ring meshing with the gear 30 is installed on the outer wall of the ring 24. The driving device 29 can drive the gear 30 to rotate and then drive the ring 24 to rotate.

[0048] Working principle: During use, when it is necessary to extrude the insulating layer 3 on the outer side of the cable shielding layer 2, first put the material for preparing the insulating layer 3 into the blanking piece 19 for melting and heating, and then pass the shielding layer 2 in transportation through the inner side of the fixed seat 10. At this time, the staff presses the adjusting rod 113 downward to move downward, so that the multiple rolling seats can be adjusted to move toward the direction of the cable shielding layer 2, thereby squeezing and limiting it in the center position, facilitating subsequent extrusion work. The downward movement of the adjusting rod 113 will squeeze the oil inside the connecting hole 112 into the inside of the annular channel 111. At this time, the oil inside the annular channel 111 will enter the inside of the transport hole 15, driving the piston rod 16 to move toward the center position of the fixed seat 10, thereby causing the movable block 116 to move toward the center of the fixed seat 10, so that the rotating rolling ball block 14 is squeezed on the outer wall of the cable shielding layer 2, which can not only limit the position of the cable shielding layer 2 to the center of the fixed seat 10, but also the rotation of the rolling ball block 14 will not affect the transportation of the cable shielding layer 2, in the molten state When the insulating layer 3 is transported to the interior of the production mechanism 12, the rotation of the ring part 24 can be controlled to drive the protrusion 25 to open a spiral groove on the outer wall of the insulating layer 3 in the molten state. After the insulating layer 3 with the spiral groove passes through the fixed seat 10 on the other side, it enters the next group of extrusion equipment that can open a double spiral groove. The internal size of this extrusion equipment is different from that of the previous group, and two groups of production mechanisms 12 will be set, and the rotation directions of the two groups of ring parts 24 are opposite. At this time, during the transportation of the insulating layer 3, it enters the extrusion die 18 to extrude the material on the outside of the insulating layer 3 to form a tensile layer 4, and a spiral block 5 will be formed on the inner side of the tensile layer 4 that is compatible with the spiral groove opened on the outside of the insulating layer 3, and the rotation of the two groups of ring parts 24 will drive the protrusion 25 to open a double spiral groove on the outside of the tensile layer 4. The driving device 29 is equipped with a gear 30, and the outer wall of the ring part 24 is equipped with a gear ring meshing with the gear 30. The driving device 29 can drive the gear 30 to rotate and then drive the ring part 24 to rotate.
