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). Summary of the invention

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] 1) This application is provided with a embrittlement cleaning assembly. The lower cover blows air to blow the loosened aluminum foil debris after cutting away from the surface of the cable, avoiding its residue due to static electricity or adhesion force, and avoiding the situation of poor welding contact on the surface of the conductor (such as copper wire) in subsequent processing procedures, avoiding the increase of impedance discontinuity and signal reflection, and preventing the jitter (Jitter) or bit error rate (BER) of high-speed signals (such as above 25Gbps) from rising.

At the same time, positive and negative ion flows are generated by the ion wind rod to neutralize the electrostatic adsorption force of the aluminum foil debris, and cooperate with the air flow blowing to remove the attached debris, making the debris easier to be stripped by the air flow.

[0021] 3) This application is provided with an off-line residue separation portion. The motor two drives the rotating rod to rotate, driving the cleaning portion to rotate. The cleaning portion rotates and contacts the surface of the wire harness. Through the friction between the flexible bristles and the surface of the wire harness, micron-sized debris adsorbed by static electricity or embedded in the gaps can be removed.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0039] Embodiment:

[0040] Please refer to Figures 1-14 , the present application provides a technical solution: a high-speed cable harness automatic aluminum foil scribing device, including 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 inside the outer frame 1 and fixed to the moving end of the X-axis moving part 3, and an aluminum foil scribing component connected to the inner frame 4;

[0041] The aluminum foil scribing component includes two sliding seats 6 slidably connected to one side of the inner frame 4, two tool holders 7 respectively fixed to one side of the two sliding seats 6, two first motors 41 fixed to the upper end of the inner frame 4, and two lead screws 42 rotatably connected to the inner wall of the inner frame 4. The two lead screws 42 are respectively screwed inside the two tool holders 7, and the output shafts of the two first motors 41 are respectively fixed to one end of the two lead screws 42;

[0042] It further includes a embrittlement cleaning component 8, and the embrittlement cleaning component 8 includes an upper cover body 81 fixedly connected to one side of one tool rest 7, a lower cover body 83 fixedly connected to one side of the other tool rest 7, a negative pressure cover body 82 fixedly connected to the upper end of the upper cover body 81, a pipe interface 84 fixedly connected 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;

[0043] It further includes a pressing part 2, and the pressing part 2 includes a cylinder 21 fixedly connected to the upper end of the outer frame body 1, a moving seat 22 slidably connected to one side of the outer frame body 1, and a pressing seat 23 fixedly connected to one side of the moving seat 22. The telescopic end of the cylinder 21 is connected to the upper end of the moving seat 22.

[0044] The pipe interface 84 is externally connected to an air pipe, and the negative pressure cover body 82 is externally connected to a negative pressure device. The high-pressure gas in the air pipe is discharged from the air outlet 85 of the lower cover body 83 and blown towards the air inlet of the upper cover body 81 to form a convection, and the residual debris on the wire harness is taken away through the convection.

[0045] By adopting the above scheme, the X-axis moving part 3 works to drive the inner frame body 4 and the aluminum foil cutting component to move in the X-axis direction (move forward), so that the upper and lower tool rests 7 can respectively move above and below the wire harness. The two motors 41 work to drive the two lead screws 42 to rotate respectively. The two lead screws 42 rotate to drive the two sliding seats 6 to move. The two sliding seats 6 move towards each other to drive the two tool rests 7 to move towards each other. The two tool rests 7 respectively cut into the upper end and the lower end of the wire harness. The X-axis moving part 3 works to drive the two tool rests 7 to move in the X-axis direction (move backward) to scrape off the laser-cut aluminum foil on the wire harness. During the process of cutting the aluminum foil, the gas in the air pipe enters the lower cover body 83 from the pipe interface 84 and is discharged from the air outlet 85 and blown towards the wire harness, blowing the loosened aluminum foil debris after cutting off the wire harness surface to avoid its residue due to static electricity or adhesion force. The negative pressure device works to generate negative pressure in the negative pressure cover body 82 and the upper cover body 81, attracting the airflow blown out from the lower cover body 83 and directly sucking and collecting it before the debris spreads. This convection method has a better effect on removing embrittled aluminum foil. At the same time, a local airflow barrier is formed through the combination of blowing and suction to prevent the debris from flying to surrounding equipment or non-cutting areas of the wire harness, reducing the environmental pollution in the workshop; the cylinder 21 works to extend and drive the moving seat 22 and the pressing seat 23 to descend. The pressing seat 23 is used to press on the fixture (the fixture is used to clamp and fix the wire harness), so that the wire harness remains stable during the process of cutting the aluminum foil.

[0046] Please refer to Figure 7 Inside the lower cover body 83, a cavity 832 communicating with the pipe interface 84 is provided, a plurality of holes 831 connecting the cavity 832 with the air outlet 85 are provided, and a baffle plate 833 for disturbing and equalizing the flow is fixedly connected to the inner wall of the cavity 832.

[0047] One side of the lower cover 83 is also fixedly connected with an ion wind bar 86 (which is used in cooperation with an ion generator and belongs to the prior art and conventional settings in the field, so it will not be elaborated here), and the air outlet end of the ion wind bar 86 penetrates through the lower cover 83 and extends into the cavity 832.

[0048] By adopting the above scheme, when the gas enters the cavity 832 from the pipeline interface 84, the baffle plate 833 can disturb and block the air flow, so that the gas distribution inside the cavity 832 is uniform. The gas in the cavity 832 enters the air outlet 85 through the hole slots 831 and is discharged from the air outlet 85. Through the design of the baffle plate 833, the air flow discharged from the air outlet 85 can be made more uniform. The ion wind bar 86 generates positive and negative ion flows to neutralize the electrostatic adsorption force of the aluminum foil debris, and cooperates with the air flow to blow and remove the attached debris, making the debris easier to be stripped by the air flow.

[0049] Please refer to Figure 8 and Figure 9 As shown in, a residual separation assembly 9 is connected to one side of both the upper cover 81 and the lower cover 83. The residual separation assembly 9 includes two movable slots 92 respectively opened on one side of the upper cover 81 and the lower cover 83, two off-line residual separation parts 93 respectively slidably connected in the two movable slots 92, and two micro cylinders 91 respectively fixedly connected to one side of the upper cover 81 and the lower cover 83. The telescopic ends of the two micro cylinders 91 are respectively connected to the two off-line residual separation parts 93.

[0050] The off-line residual separation part 93 includes a seat body 931 slidably connected in the movable slot 92, a rotating rod 933 rotatably connected to the inner wall of the seat body 931, a cleaning part 934 sleeved outside the rotating rod 933, and a motor two 932 fixedly connected to one side of the seat body 931. The output shaft of the motor two 932 penetrates through the seat body 931 and is fixedly connected to one end of the rotating rod 933.

[0051] By adopting the above scheme, when the tool holder 7 contacts the wire harness and cuts the tool holder 7, the micro cylinder 91 works to extend and drives the seat body 931 to move in the movable slot 92. The seat body 931 drives the cleaning part 934 (flexible brush, which can be made of conductive nylon material, anti-static and wear-resistant) to move towards the wire harness. The motor two 932 works to drive the rotating rod 933 to rotate. The rotating rod 933 rotates to drive the cleaning part 934 to rotate. The cleaning part 934 cleans the brittle aluminum foil remaining outside the wire harness. The cleaning 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, the micron-sized debris adsorbed electrostatically or embedded in the gaps can be removed. At the same time, the burrs at the cutting edge of the aluminum foil can also be smoothed. The debris is lifted by the rotation of the cleaning part 934, and it is easier to capture the escaping particles in cooperation with the blowing and suction air flow. Especially, the cleaning effect on the metal debris with higher density is more obvious.

[0052] Please refer to Figures 10-14, an annular groove 935 is formed in the inner wall of the seat body 931, and an elastic reset portion 94 is connected in the annular groove 935. One end of the cleaning portion 934 is fixedly connected with an annular insertion end 936, and the annular insertion end 936 is movably inserted into the annular groove 935.

[0053] 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 in the inner wall of the seat body 931. Bevels 97 are formed on the outer surface of the flange 96 and the inner wall of the groove 95.

[0054] The elastic reset portion 94 includes a spring 941 fixedly connected to the inner wall of the annular groove 935, a ring body 942 fixedly connected 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. The ball 943 contacts the annular insertion end 936.

[0055] By adopting the above scheme, when the cleaning portion 934 rotates, the flange 96 will move out through the bevel 97 on the inner wall of the groove 95. When the flange 96 moves out of the groove 95, it can drive the cleaning portion 934 to move laterally outside the rotating rod 933. The annular insertion end 936 at one end of the cleaning portion 934 will squeeze the ring body 942 and the spring 941, causing the spring 941 to compress. When the flange 96 rotates with the cleaning portion 934 and re-enters the groove 95, the spring 941 generates a force to push the cleaning portion 934 to move and reset outside the rotating rod 933. The reciprocating movement of the cleaning portion 934 outside the rotating rod 933 can ensure that the bristles cover the entire surface area of the cable, avoid the cleaning blind area caused by fixed rotation, disrupt the debris adhesion state by changing the moving direction, overcome the "embedding" phenomenon of debris caused by a single rotating direction, and improve the cleaning effect on the brittle aluminum foil residue.

[0056] Working principle: The X-axis moving portion 3 works to drive the inner frame body 4 and the aluminum foil scribing assembly to move in the X-axis direction (move forward), so that the upper and lower tool seats 7 can move above and below the wire harness respectively. Two motors 41 work to drive two lead screws 42 to rotate respectively. The rotation of the two lead screws 42 drives two sliding seats 6 to move. The two sliding seats 6 move towards each other to drive the two tool seats 7 to move towards each other. The two tool seats 7 respectively cut into the upper end and the lower end of the wire harness. The X-axis moving portion 3 works to drive the two tool seats 7 to move in the X-axis direction (move backward) to scribe the aluminum foil on the wire harness that has been laser cut.
