Description

Technical Field

[0001] This application relates to the field of cable manufacturing, and in particular to a smart detection cable for high-end medical equipment and its manufacturing process. Background Technology

[0002] Modern medical technology often relies on intelligent medical testing equipment to diagnose patients' conditions. The detection information from these devices is transmitted via cables to information processing and display components, where it is then presented as images. To achieve high-definition image transmission, the cables used for transmission in medical equipment need to be able to shield against interference from external environmental factors such as electromagnetic waves and ionizing radiation.

[0003] During cable production, a layer of soft copper tape needs to be wrapped around the cable core to form a shielding layer. This wrapping process typically involves installing a rotating disc at the cable routing point, mounting the soft copper tape on the disc, and then winding it around the cable as the disc rotates. Because the soft copper tape has a certain degree of flexibility, when the cable is bent or twisted during use, there will inevitably be a deviation in deformation between the soft copper tape and the cable core. This allows the edges of the soft copper tape to easily cut into the cable core, inevitably leading to core damage after prolonged use and affecting the cable's lifespan. Summary of the Invention

[0004] To reduce the cutting effect of soft copper strips on the wire core in cables for medical equipment, this application provides an intelligent detection cable for high-end medical equipment and its manufacturing process.

[0005] This application provides a high-end intelligent detection cable for medical devices and its manufacturing process, which adopts the following technical solution: A high-end intelligent testing cable for medical devices includes multiple core wires, a metal shielding layer, and an insulating outer layer. The metal shielding layer simultaneously covers the multiple core wires and is formed by spirally overlapping and winding a soft copper strip. The soft copper strip includes a strip body, a first inclined side, and a second inclined side. The first inclined side and the second inclined side are located on opposite sides of the strip body. The angle formed between the first inclined side and the strip body is away from the center of the metal shielding layer, while the angle formed between the second inclined side and the strip body is towards the center of the metal shielding layer. In the spirally wound state, the second inclined side overlaps the first inclined side.

[0006] By adopting the above technical solution, a soft copper strip is wound around multiple parallel wire cores to form a metal shielding layer. The soft copper strip is wound to form a spiral loop. The second inclined edge of the later-formed spiral loop overlaps with the first inclined edge of the earlier-formed spiral loop. Although the second inclined edge is inclined towards the wire core, it is isolated from the wire core, making it difficult for the edge of the second inclined edge to cut the wire core. On the other hand, the first inclined edge is closer to the wire core than the second inclined edge, but its edge is inclined away from the wire core, making it difficult for the first inclined edge to cut the wire core. Therefore, when the cable twists during use, the soft copper strip of the metal shielding layer is less likely to cut the wire core and the outer insulation layer, which helps to extend the service life of the cable. In addition, during the winding process, the overlap between the first and second inclined edges helps to control the spiral spacing of the soft copper strip during spiral winding, thus helping to ensure the shielding effect of the metal shielding layer.

[0007] Optionally, a metal wire is spirally wound around the outside of the metal shielding layer. The winding pitch of the metal wire is equal to the winding pitch of the soft copper strip. The winding position of the metal wire on the soft copper strip is located in the angle region between the strip body and the first inclined side.

[0008] By adopting the above technical solution, when the cable is bent during use, the gap between the first and second inclined sides is prone to increase with the deformation of the cable. However, by placing the winding position of the metal wire in the angled area between the main body of the cable and the first inclined side, the metal wire can shield the gap between the first and second inclined sides, thereby reducing the impact of electromagnetic waves on the wire core after passing through the gap between the first and second inclined sides.

[0009] Optionally, the angle of the first hypotenuse is greater than the angle of the second hypotenuse.

[0010] By adopting the above technical solution, during the spiral winding of the soft copper strip, the second inclined side overlaps with the first inclined side. By making the fold angle of the first inclined side larger than that of the second inclined side, it is beneficial to ensure that the second inclined side and the first inclined side can fit together fully when they overlap.

[0011] Optionally, the width of the first inclined side is greater than or equal to the width of the second inclined side, the radius of the metal wire is greater than or equal to the thickness of the soft copper strip, the edge of the second inclined side abuts against the outer peripheral surface of the metal wire, and the metal wire is used to force the second inclined side to press against the corresponding first inclined side.

[0012] By adopting the above technical solution, when the soft copper strip is wound, the edge of the second inclined side abuts against the part of the metal wire near the strip body, and the metal wire can prevent the first inclined side and the second inclined side from separating from each other, thereby helping to control the gap width between the first inclined side and the second inclined side.

[0013] Optionally, the strip body is provided with protrusions spaced apart along its length, the protrusions being located on the side of the strip body closer to the wire core; the protrusions of the soft copper strip are located between two adjacent wire cores.

[0014] By adopting the above technical solution, the bump is set between two adjacent wire cores. The bump can prevent the relative sliding between the soft copper strip and the wire core in the circumferential direction, thereby improving the stability of the connection between the wire core and the metal shielding layer.

[0015] Optionally, the main body of the tape has multiple recesses on the side away from the wire core, and the recesses are used to fill the adhesive of the insulating outer layer.

[0016] By adopting the above technical solution, the flowing adhesive fills the concave points of the main body of the insulating outer layer during the molding process. After the insulating outer layer cools and solidifies, the connection between the insulating outer layer and the metal shielding layer can be strengthened.

[0017] Optionally, the surface of the metal shielding layer is provided with a plurality of adhesive dots along the length direction. The adhesive dots are used to bond the metal wire and the soft copper strip, and the insulating outer layer is bonded and fixed to the adhesive dots.

[0018] By adopting the above technical solution, the adhesive dots can improve the connection strength between the metal shielding layer and the metal wire.

[0019] Optionally, the soft copper strip is drawn away from the surface of the wire core.

[0020] By adopting the above technical solution, the side of the soft copper strip away from the wire core is connected to the outer insulation layer, and the side of the soft copper strip core is roughened, which can improve the adhesion between the outer insulation layer and the soft copper strip, thereby improving the connection strength between the outer insulation layer and the soft copper strip.

[0021] A manufacturing process for a high-end medical device intelligent detection cable includes the following steps: To process soft copper strip, roll forming equipment is used to roll and form the first and second bevels on the soft copper strip. The roll-formed soft copper strip is then rolled into a soft copper strip roll. The rolling device includes a base, a first side roller group, a second side roller group, and two intermediate roller groups. The intermediate roller groups are used to form the main body of the soft copper strip. The first side roller group is used to form the first inclined edge of the soft copper strip, and the second side roller group is used to form the second inclined edge of the soft copper strip. The two second intermediate roller groups are arranged side by side along the material feeding direction of the rolling device. The first side roller group and the second side roller group are located between the two intermediate roller groups. The soft copper strip is wound onto a wire harness consisting of multiple wire cores using a soft copper strip winding device.

[0022] By adopting the above technical solution, the first side roller group and the second side roller group are both set between the two intermediate roller groups, so that the first side roller group and the second side roller group are misaligned with the intermediate roller group along the material feeding direction of the rolling device. This helps to make the first side roller group, the second side roller group and the intermediate roller group roll the soft copper strip as fully as possible while overcoming the interference problem between the first side roller group, the second side roller group and the intermediate roller group.

[0023] Optionally, the base is provided with a trimming assembly for removing burrs from both sides of the soft copper strip.

[0024] By adopting the above technical solution, the burrs on both sides of the soft copper strip are removed by the trimming component, so as to further reduce the cutting effect of the soft copper strip on the wire core and the outer insulation layer.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. A soft copper strip is wound around multiple parallel wire cores to form a metal shielding layer. The soft copper strip is wound to form a spiral loop. The second inclined edge of the later-formed spiral loop overlaps the first inclined edge of the earlier-formed spiral loop. Although the second inclined edge is inclined towards the wire core, it is isolated from the wire core, making it difficult for the edge of the second inclined edge to cut the wire core. The edge of the first inclined edge is inclined away from the wire core, making it difficult for the first inclined edge to cut the wire core, which helps to extend the service life of the cable.

[0026] 2. During the spiral winding of the soft copper strip, the second inclined side overlaps the first inclined side. By making the fold angle of the first inclined side larger than that of the second inclined side, it is beneficial to ensure that the second inclined side and the first inclined side can fit together fully when they overlap.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses an intelligent detection cable for high-end medical devices. (Refer to...) Figure 1 , Figure 2 and Figure 3 The intelligent detection cable for high-end medical equipment includes multiple wire cores 1, filler 2, metal shielding layer 3 and insulating outer layer 4. The wire core 1 is a conductor with an insulating layer on its surface. In this embodiment, there are three wire cores 1. The metal shielding layer 3 covers all three wire cores 1. The filler 2 fills the gaps between adjacent wire cores 1 and the gaps between the wire core 1 and the inner circumferential surface of the metal shielding layer 3. The metal shielding layer 3 is formed by spirally winding soft copper strips 31 in an interlaced manner.

[0036] Reference Figure 1 The soft copper strip 31 includes a strip body 313, a first inclined side 311, and a second inclined side 312. The strip body 313, the first inclined side 311, and the second inclined side 312 are integrally formed. The first inclined side 311 and the second inclined side 312 are located on both sides of the strip body 313. The first inclined side 311 and the second inclined side 312 form obtuse angles with the strip body 313. The angle between the first inclined side 311 and the strip body 313 is away from the center of the metal shielding layer 3. The angle between the second inclined side 312 and the strip body 313 is towards the center of the metal shielding layer 3. The soft copper strip 31 is wound to form a continuous spiral strip loop. The second inclined side 312 of the spiral strip loop formed later overlaps the first inclined side 311 of the spiral strip loop formed earlier.

[0037] Reference Figure 1A metal wire 6 is spirally wound on the outside of the metal shielding layer 3. The metal wire 6 is a copper wire. The radius of the metal wire 6 is greater than the thickness of the soft copper strip 31. The metal wire 6 and the soft copper strip 31 of the metal shielding layer 3 are wound synchronously, so that the winding pitch of the metal wire 6 is equal to the winding pitch of the soft copper strip 31. The winding position of the metal wire 6 on the soft copper strip 31 is located in the angle region between the strip body 313 and the first inclined side 311.

[0038] When the soft copper strip 31 is spirally wound in an interlaced manner, there is a gap between the first inclined side 311 and the second inclined side 312. The metal wire 6 can shield the gap between the first inclined side 311 and the second inclined side 312, so that external electromagnetic waves are less likely to interfere with the information transmission process of the wire core 1 by passing through the gap between the first inclined side 311 and the second inclined side 312.

[0039] Reference Figure 3 When the soft copper strip 31 is in a relaxed state, the angle of the first inclined side 311 is greater than the angle of the second inclined side 312, that is, the angle between the first inclined side 311 and the strip body 313 is less than the angle between the second inclined side 312 and the strip body 313. The width of the first inclined side 311 is greater than or equal to the width of the second inclined side 312. The edge of the second inclined side 312 abuts against the outer peripheral surface of the metal wire 6. The metal wire 6 is used to force the second inclined side 312 to press against the corresponding first inclined side 311, so as to prevent the first inclined side 311 and the second inclined side 312 from separating from each other.

[0040] Normally, when a cable is bent, the gap width between the first inclined edge 311 and the second inclined edge 312 tends to change accordingly. However, by tightening the soft copper strip 31 spirally around the first inclined edge 311, the second inclined edge 312 exerts pressure on the first inclined edge. Since the slope of the second inclined edge 312 is greater than that of the first inclined edge 311, the first inclined edge 311 deforms under the pressure of the second inclined edge 312. In this case, even if the cable bends during use, a tight fit between the first inclined edge 311 and the second inclined edge 312 can be ensured. Furthermore, the metal wire 6 can limit the second inclined edge 312, thereby further suppressing the widening of the gap between the first inclined edge 311 and the second inclined edge 312.

[0041] Reference Figure 3The soft copper strip 31 has a strip body 313 with equidistant protrusions 3131 along its length formed by pressing. The protrusions 3131 are located on the side of the strip body 313 closer to the wire core 1, and the side of the strip body 313 away from the wire core 1 has multiple concave points 3132 corresponding to the protrusions 3131 formed by pressing. The protrusions 3131 of the soft copper strip 31 are located between two adjacent wire cores 1. The protrusions 3131 are embedded in the filler 2, so that the combination of the soft copper strip 31, the filler 2 and the wire core 1 is less likely to have relative displacement along the circumference, which helps to ensure a more reliable connection between the metal shielding layer 3 and the wire core 1.

[0042] The surface of the soft copper strip 31 is drawn away from the core 1, which enhances the auxiliary effect between the outer insulating layer 4 and the metal shielding layer 3.

[0043] Reference Figure 1 A plurality of adhesive dots 32 are evenly spaced along the length of the surface of the metal shielding layer 3. The adhesive dots 32 are used to bond the metal wire 6 and the soft copper strip 31, and the insulating outer layer 4 is bonded and fixed to the adhesive dots 32. The adhesive dots 32 are formed by spraying adhesive at intervals onto the surface of the metal shielding layer 3 using a dispensing machine. The adhesive dots 32 can improve the connection strength between the metal wire 6 and the metal shielding layer 3.

[0044] In an embodiment of this application, the metal shielding layer 3 of a high-end medical device intelligent detection cable is formed by winding a soft copper strip 31 around multiple parallel wire cores 1. During the winding process, the second inclined side 312 overlaps the first inclined side 311. Although the second inclined side 312 is inclined towards the wire core 1, it is isolated from the wire core 1, making it difficult for the edge of the second inclined side 312 to cut the wire core 1. On the other hand, the first inclined side 311 is closer to the wire core 1 than the second inclined side 312, but the edge of the first inclined side 311 is inclined away from the wire core 1, making it difficult for the first inclined side 311 to cut the wire core 1. Therefore, when the cable twists during use, the soft copper strip 31 of the metal shielding layer 3 is less likely to cut the wire core 1 and the outer insulation layer 4, which helps to extend the service life of the cable.

[0045] This embodiment also discloses a manufacturing process for intelligent detection cables for high-end medical devices, including the following steps: S1, process soft copper strip 31, use roll forming equipment to roll form the first oblique edge 311 and the second oblique edge 312 on the soft copper strip 31, roll form the soft copper strip 31 into soft copper strip 31 coil, and use trimming device to remove the burrs on both sides of the soft copper strip 31 before rolling. Reference Figures 4-6The rolling device 7 includes a base 74, a first side roller group 71, a second side roller group 72, and two intermediate roller groups 73. The intermediate roller groups 73 are used to form the main body 313 of the soft copper strip 31. The first side roller group 71 is used to form the first inclined edge 311 of the soft copper strip 31, and the second side roller group 72 is used to form the second inclined edge 312 of the soft copper strip 31. The two second intermediate roller groups 73 are arranged parallel to each other along the material feeding direction of the rolling device 7. The first side roller group 71 and the second side roller group 72 are both intermediate roller groups 73. The first side roller group 71 includes a first active roller 711 and a first driven roller 712; the second side roller group 72 includes a second active roller 721 and a second driven roller 722; the intermediate roller group 73 includes an intermediate active roller 731 and an intermediate driven roller 732. The intermediate active roller 731 is provided with dot-shaped protrusions 733, and the intermediate driven roller 732 is provided with dot-shaped recesses 734 corresponding to the dot-shaped protrusions 733. The dot-shaped protrusions 733 and the dot-shaped recesses 734 are used together to press out protrusions 3131 on the belt body 313. Reference Figure 6 The base 74 is also provided with two limiting members 75, which are arranged opposite to each other. The two limiting members 75 are used to limit the soft copper strip 31 before rolling. Each of the two limiting members 75 is provided with a trimming assembly 76 on its opposite side. The trimming assembly 76 includes two trimming scrapers 761, which are arranged along the material feeding direction of the rolling device 7 and are arranged to cross each other. When the soft copper strip 31 passes through the trimming assembly 76, the two trimming scrapers 761 respectively perform trimming on the same edge of the soft copper strip 31. S2, using a soft copper strip 31 winding device, the soft copper strip 31 is wound onto the wire harness assembly of the wire core 1 and the filler 2 to form a metal shielding layer 3 covering the wire core 1. S3, an insulating outer layer 4 is formed by extruding the metal shielding layer 3 onto the surface of the metal shielding layer 3 using an extruder.

[0046] The first side roller group 71 and the second side roller group 72 are respectively misaligned with the intermediate roller group 73 along the material feeding direction of the rolling device 7. This helps to overcome the interference problem between the first side roller group 71, the second side roller group 72 and the intermediate roller group 73, and to make the first side roller group 71, the second side roller group 72 and the intermediate roller group 73 roll the soft copper strip 31 as fully as possible. After the soft copper strip 31 is deburred by the trimming assembly 76, the cutting effect of the soft copper strip 31 on the wire core 1 and the outer insulating layer 4 can be further reduced.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
