Description

Technical Field

[0001] The present invention relates to the technical field of cables, and more particularly to a long-distance industrial robot bending and torsion-resistant drag chain cable. Background Art

[0002] Drag chain cables are cables used in drag chain chains to prevent entanglement, abrasion, pullout, and unraveling. They are often used in applications where equipment units need to move back and forth. These cables are highly flexible, and because the drag chain resembles a tank track, cables used in these chains are also called tank chain cables or drag cables. However, traditional drag chain cables can become entangled during movement, and because the drag chain is made of a rigid material, bending the cables is difficult and lacks flexibility. Industrial robots are the most typical mechatronic digital equipment. Due to the complexity of robot operations, robot cables must be able to withstand reciprocating bending, twisting, and long-stroke sliding, while also exhibiting a certain degree of wear resistance. Currently, drag chain cables with resistant flexibility are frequently used in the robotics industry, but the overall flexibility of existing drag chain cables remains unsatisfactory. Flexibility largely determines the cable's flex resistance. Their structure typically consists of several stranded conductors composed of ultra-fine monofilaments, which are first insulated, then twisted into a cable, and finally extruded with an outer sheath. However, this structure cannot guarantee long-term stable operation in applications where there is continuous and frequent twisting and bending, and is even less suitable for applications that require rapid movement or long-distance movement. Furthermore, the tensile strength of the cable's outermost sheath needs to be improved. Without ideal tensile strength, the cable will wear and tear during long-distance mechanical movement, ultimately shortening its service life and delaying production cycles.

[0003] A long-distance industrial robot bending and torsion-resistant drag chain cable similar to patent number: CN201910535097.9, the long-distance industrial robot bending and torsion-resistant drag chain cable includes: a cable core, an inner sheath wrapping the cable core, annular bosses equidistantly arranged on the inner sheath along the axial direction, and an outer sheath arranged between any two adjacent annular bosses. The beneficial effects of this invention are: it has better bending and torsion resistance, protecting the cable core from being easily broken during the bending and torsion process, and the cable core is easy to move during long-distance mobile mechanical movement, which can effectively reduce the wear on the cable core and extend the service life of the cable core; the cable cannot gradually integrate components such as conductors, insulation layers, and shielding layers from a planar arrangement into a compact cylindrical structure, and cannot simultaneously ensure high flexibility and bending and torsion resistance; it cannot be adapted for use in different environments after achieving bending and torsion resistance and protection strength.

A hot melt edge sealing heating rod 33 is fixed at a designated position in the upper edge sealing press 32; the hot melt edge sealing heating rod 33 is electrically connected to the hot melt control device;

[0086] The working principle and beneficial effects of this embodiment are as follows: the vortex inner layer 1 formed by the vortex is added between the lower edge sealing press plate 31 and the upper edge sealing press plate 32 through the limitation of the circular limiting inserting platform 13, and the frequency conversion controlled second driver 26 drives the reciprocating edge sealing shaft 27 to rotate, and then drives the left rack slide 29 and the right rack slide 30 to slide relative to each other through the meshing of the gears, so that the lower edge sealing press plate 31 and the upper edge sealing press plate 32 are synchronously clamped inwardly or synchronously driven outwardly, thereby realizing the clamping and loosening of the vortex inner layer 1. During the clamping process, the hot-melt edge sealing heating rod 33 located at the middle end of the upper edge sealing press plate 32 is controlled to extrude the hot-melt edge sealing at the outer end opening of the vortex inner layer 1 so that it melts and then bonds together to form a whole for use; continuous hot-melt edge sealing is achieved through control; after the edge sealing is completed, it is continuously driven to be added to the tail end conveyor 10;

[0087] The tail end conveyor 10 includes a third driver 34, a lower driving roller 36, a connecting gear roller 37 and an upper driving arc roller 38. The third driver 34 drives the conveying roller 11, the lower driving roller 36 and the upper driving arc roller 38 to rotate through the same transmission principle as above, through gear meshing and connecting gear roller 37, and then outputs the processed vortex-shaped vortex inner layer 1 after cooling; and then makes it connect and sleeved in the drag chain rubber sleeve 4 to complete the assembly of the drag chain cable.

[0088] The above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the scope of protection of the present invention.
