Description

Technical Field

[0001] The present application relates to the technical field of automatic processing of cable harnesses, and in particular to an automatic aluminum foil cutting device for high-speed cable harnesses. Background Art

[0002] High-speed cable harnesses are complex cable assemblies designed specifically for high-frequency, high-speed signal transmission. Their structural design must meet signal integrity (SI), electromagnetic compatibility (EMC) and mechanical reliability requirements. The harnesses are composed of conductors, insulation layers, shielding layers, ground wires and other structures.

[0003] The shielding layer of the wire harness is generally made of aluminum foil and wrapped around the outside of the conductor. When the wire harness is connected to the connector, the wire harness needs to be processed to strip the insulation layer and the shielding layer to expose the conductor and the ground wire. In order to realize the automatic stripping of the aluminum foil, the existing patent (Announcement No. CN213583257U) discloses an automatic aluminum foil cutting device for high-speed cable harnesses. The aluminum foil cutting tool is driven up and down and translated by the upper and lower cylinders and the translation cylinder to cut the core wire of the wire harness. Although the automation of the aluminum foil cutting of the cable harness can be realized, improper cylinder pressure control or cutter wear may result in incomplete cutting (residual aluminum foil affects welding) or excessive cutting (damage to the internal conductor or insulation layer). Therefore, the prior art usually adopts a combination of laser cutting and cutter cutting. First, a precise cutting line (partial penetration or marking path) is engraved on the surface of the aluminum foil by laser to reduce the resistance and error of subsequent mechanical cutting, and then the low-pressure cylinder or servo-driven tool is used to complete the final cutting and stripping along the laser path to avoid wear or overcutting caused by direct contact of the mechanical tool with the aluminum foil.

[0004] Although the combination of laser and cutter cutting can improve the cutting accuracy of aluminum foil, the high energy density of the laser causes the aluminum foil to heat up locally to above the melting point in a very short time (such as microseconds or nanoseconds), and then quickly cools due to the thermal conductivity of the surrounding material, which reduces the ductility of the material and causes the material to become more brittle. At the same time, aluminum easily reacts with oxygen in the air at high temperatures to form aluminum oxide. Aluminum oxide has high hardness but high brittleness, which leads to the formation of a brittle layer on the surface of the aluminum foil. Therefore, the aluminum foil after laser heating has significantly reduced ductility due to grain refinement, oxidation or amorphization. When external force is applied during mechanical peeling, it is difficult for the material to absorb energy through plastic deformation, and instead releases stress in the form of brittle fracture. During mechanical peeling, interface separation may be accompanied by tearing of the aluminum foil (fragment collapse and residue). If the aluminum foil debris remaining after peeling is not completely removed, it may adhere to the surface of the conductor (such as copper wire) in subsequent processing steps, resulting in poor contact during welding, increased impedance discontinuity and signal reflection, and causing jitter (Jitter) or bit error rate (BER) of high-speed signals (such as above 25Gbps).

[0037] Example:

[0038] See also Figure 1-Figure 14 , the present application provides a technical solution: an automatic aluminum foil marking device for a high-speed cable harness, comprising an outer frame 1, an X-axis moving part 3 connected to one side of the outer frame 1, an inner frame 4 slidably connected to the inside of the outer frame 1 and fixed to the moving end of the X-axis moving part 3, and an aluminum foil marking assembly connected to the inner frame 4;

[0039] The aluminum foil cutting assembly includes two slide seats 6 slidably connected to one side of the inner frame 4, two knife seats 7 respectively fixed to one side of the two slide seats 6, two motors 41 fixed to the upper end of the inner frame 4, and two screw rods 42 rotatably connected to the inner wall of the inner frame 4, and the two screw rods 42 are respectively screwed inside the two knife seats 7, and the output shafts of the two motors 41 are respectively fixed to one end of the two screw rods 42;

[0040] It also includes an embrittlement cleaning assembly 8, and the embrittlement cleaning assembly 8 includes an upper cover body 81 fixed to one side of one of the knife seats 7, a lower cover body 83 fixed to one side of the other knife seat 7, a negative pressure cover body 82 fixed to the upper end of the upper cover body 81, a pipe interface 84 fixed to the lower end of the lower cover body 83, an air outlet 85 opened at the upper end of the lower cover body 83, and an air inlet opened at the lower end of the upper cover body 81;

[0041] It also includes a clamping part 2, and the clamping part 2 includes a cylinder 21 fixedly connected to the upper end of the outer frame 1, a moving seat 22 slidably connected to one side of the outer frame 1, and a pressing seat 23 fixedly connected to one side of the moving seat 22, and the telescopic end of the cylinder 21 is connected to the upper end of the moving seat 22.

[0042] The pipe interface 84 is connected to an air pipe, the negative pressure cover 82 is connected to a negative pressure device, and the high-pressure gas in the air pipe is discharged from the air outlet 85 of the lower cover 83 and blown to the air inlet of the upper cover 81 to form convection, thereby removing the debris remaining on the wiring harness through convection.

[0043] By adopting the above scheme, the X-axis moving part 3 works to drive the inner frame 4 and the aluminum foil cutting assembly to move in the X-axis direction (move forward), so that the upper and lower knife seats 7 can move to the top and bottom of the wiring harness respectively, and the two motors 41 work to drive the two screw rods 42 to rotate respectively, and the two screw rods 42 rotate to drive the two slides 6 to move, and the two slides 6 move towards each other to drive the two knife seats 7 to move towards each other, and the two knife seats 7 cut into the upper and lower ends of the wiring harness respectively, and the X-axis moving part 3 works to drive the two knife seats 7 to move in the X-axis direction (move backward) to cut off the aluminum foil on the wiring harness that has been laser cut. In the process of cutting the aluminum foil, the gas in the air pipe enters the lower cover 83 from the pipeline interface 84 and exits from the air outlet 8 5 is discharged and blown toward the wire harness, and the loose aluminum foil debris after cutting is blown away from the cable surface to avoid it remaining due to static electricity or adhesion. The negative pressure device works to generate negative pressure in the negative pressure cover 82 and the upper cover 81, and attracts the airflow blown out from the lower cover 83, and directly absorbs and collects the debris before it spreads. This convection method has a better effect on removing brittle aluminum foil. At the same time, a local airflow barrier is formed through the blowing and suction linkage to prevent the debris from flying to the surrounding equipment or the non-cutting area of ​​the cable, thereby reducing the environmental pollution in the workshop; the cylinder 21 can work and extend to drive the moving seat 22 and the pressure seat 23 to descend. The pressure seat 23 is used to press on the clamp (the clamp is used to clamp and fix the cable harness) to keep the harness stable during the aluminum foil cutting process.

[0044] See also Figure 7 The lower cover 83 has a cavity 832 in communication with the pipe interface 84 and a plurality of holes 831 in communication with the air outlet 85 . A flow partition 833 for disturbing and uniforming the flow is fixedly connected to the inner wall of the cavity 832 .

[0045] An ion wind rod 86 (used in conjunction with an ion generator, which belongs to the prior art and conventional settings in the field and will not be described in detail here) is also fixedly connected to one side of the lower cover body 83 , and the air outlet end of the ion wind rod 86 passes through the lower cover body 83 and extends into the cavity 832 .

[0046] By adopting the above scheme, when the gas enters the cavity 832 from the pipe interface 84, the flow partition 833 can disturb and block the airflow, so that the gas inside the cavity 832 is evenly distributed, and the gas in the cavity 832 enters the air outlet 85 through the hole groove 831 and is discharged from the air outlet 85. The design of the flow partition 833 can make the airflow discharged from the air outlet 85 more uniform, and the positive and negative ion flows are generated by the ion wind rod 86 to neutralize the electrostatic adsorption force of the aluminum foil debris, and the airflow is used to blow away the attached debris, so that the debris can be more easily peeled off by the airflow.

[0047] See also Figure 8 and Fig. 9 The upper cover body 81 and the lower cover body 83 are both connected to a residual separation component 9 on one side, and the residual separation component 9 includes two movable grooves 92 respectively opened on one side of the upper cover body 81 and the lower cover body 83, two off-line residual separation parts 93 respectively slidably connected to the two movable grooves 92, and two micro cylinders 91 respectively fixed on one side of the upper cover body 81 and the lower cover body 83, and the telescopic ends of the two micro cylinders 91 are respectively connected to the two off-line residual separation parts 93.

[0048] The off-line residual separation part 93 includes a seat body 931 slidably connected in the movable groove 92, a rotating rod 933 rotatably connected to the inner wall of the seat body 931, a cleaning part 934 sleeved on the outside of the rotating rod 933, and a second motor 932 fixedly connected to one side of the seat body 931, and the output shaft of the second motor 932 passes through the seat body 931 and is fixedly connected to one end of the rotating rod 933.

[0049] By adopting the above scheme, when the knife seat 7 contacts the wire harness and cuts the knife seat 7, the micro cylinder 91 extends out and drives the seat body 931 to move in the movable groove 92, and the seat body 931 drives the cleaning brush part 934 (a flexible brush, which can be made of conductive nylon material, anti-static and wear-resistant) to move toward the wire harness, and the motor 2 932 drives the rotating rod 933 to rotate, and the rotation of the rotating rod 933 drives the cleaning brush part 934 to rotate, and the brittle aluminum foil remaining on the outside of the wire harness is cleaned by the cleaning brush part 934, and the cleaning brush part 934 rotates and contacts the surface of the wire harness. Through the friction between the flexible bristles and the surface of the wire harness, micron-level debris that is electrostatically adsorbed or embedded in the gap can be removed, and the burrs on the cutting edge of the aluminum foil can also be smoothed. The debris is lifted up by the rotation of the cleaning brush part 934, and the escaping particles are more easily captured in combination with the blowing and suction airflow, especially for the metal debris with higher density. The removal effect is more significant.

[0050] See also Figure 10-Figure 14An annular groove 935 is provided on the inner wall of the seat body 931 , and an elastic reset portion 94 is connected in the annular groove 935 . An annular insertion end 936 is fixedly connected to one end of the cleaning portion 934 , and the annular insertion end 936 is movably inserted in the annular groove 935 .

[0051] A plurality of flanges 96 are integrally formed at one end of the cleaning portion 934 , and a plurality of grooves 95 for accommodating the plurality of flanges 96 are formed on the inner wall of the seat body 931 . The outer surface of the flange 96 and the inner wall of the groove 95 are both formed with inclined surfaces 97 .

[0052] The elastic reset portion 94 includes a spring 941 fixed to the inner wall of the annular groove 935, a ring body 942 fixed to the other end of the spring 941 and slidably connected in the annular groove 935, and a ball 943 rotatably connected to one side of the ring body 942, and the ball 943 is in contact with the annular insertion end 936.

[0053] By adopting the above scheme, when the cleaning part 934 rotates, the flange 96 will move out through the inclined surface 97 on the inner wall of the groove 95. When the flange 96 moves out of the groove 95, it can drive the cleaning part 934 to move laterally outside the rotating rod 933. The annular insertion end 936 at one end of the cleaning part 934 will squeeze the ring body 942 and the spring 941 to compress the spring 941. When the flange 96 rotates with the cleaning part 934 and re-enters the groove 95, the spring 941 generates a force to push the cleaning part 934 to move and reset outside the rotating rod 933. The reciprocating motion of the cleaning part 934 outside the rotating rod 933 can ensure that the bristles cover the entire area of ​​the cable surface, avoid the cleaning blind area caused by fixed rotation, disrupt the debris attachment state by changing the moving direction, overcome the debris "embedded" phenomenon caused by a single rotation direction, and improve the cleaning effect of brittle aluminum foil residues.

[0054] Working principle: The X-axial moving part 3 drives the inner frame 4 and the aluminum foil cutting assembly to move in the X-axial direction (move forward), so that the upper and lower knife seats 7 can move to the top and bottom of the wiring harness respectively, and the two motors 41 work to drive the two screw rods 42 to rotate respectively, and the two screw rods 42 rotate to drive the two slides 6 to move, and the two slides 6 move towards each other and drive the two knife seats 7 to move towards each other. The two knife seats 7 cut into the upper and lower ends of the wiring harness respectively, and the X-axial moving part 3 works to drive the two knife seats 7 to move in the X-axial direction (move backward) to cut off the aluminum foil on the wiring harness that has been laser cut.
