Description

Technical Field

[0001] This utility model relates to the field of conductive component manufacturing technology, and more specifically, to a conductive component production line. Background Technology

[0002] Conductive components constitute a significant portion of the cost of high-voltage connector wiring harnesses in electric vehicles. They are primarily used to connect battery packs and generators, as well as to charge the battery packs. Current generation conductive components consist of a core material, an insulating layer covering the core material, and an armor layer covering the insulating layer. The insulating layer blocks current, while the armor layer provides waterproofing, protection, and magnetic shielding.

[0003] Existing technology first coats an insulating layer around a core material to obtain an insulating conductive component, then prepares an armor layer sleeve, and finally fits the sleeve over the insulating conductive component coated with the insulating layer. A drawing die is then used to tightly adhere the armor layer to the insulating layer, completing the armor layer coating. However, in existing technology, the armor layer sleeve and the insulating conductive component are prepared separately, and the drawing process to tightly adhere the armor layer to the insulating layer needs to be performed separately. This makes continuous production impossible, resulting in low production efficiency and high costs. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects in the existing technology and provide a conductive component production line to realize the continuous production of the armor layer.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A conductive component production line includes a core material conveying unit, an extrusion coating unit, a continuous extrusion coating unit, an armor collection unit arranged in sequence, and two armor blank conveying units arranged in parallel, wherein the armor blank conveying units are arranged before the continuous extrusion coating unit; The core material conveying unit is used to convey the core material to the extrusion coating unit, and the extrusion coating unit is used to extrude and coat the insulating layer onto the core material to obtain an insulating conductive component; the armored blank conveying unit is used to convey the armored blank to the continuous extrusion coating unit, and the continuous extrusion coating unit is used to continuously extrude the armored blank and coat it over the insulating conductive component to obtain an armored conductive component; the collecting unit is used to collect the armored conductive component.

[0006] Implementing the embodiments of this utility model will have the following beneficial effects: The conductive component production line in this embodiment includes a core material conveying unit, an extrusion coating unit, a continuous extrusion coating unit, an armor collection unit, and two armor blank conveying units arranged in parallel, with the armor blank conveying units positioned before the continuous extrusion coating units. The core material conveying unit conveys the core material to the extrusion coating unit, which extrudes and coats the core material with an insulating layer to obtain an insulating conductive component. The armor blank conveying unit conveys the armor blank to the continuous extrusion coating unit, which continuously extrudes and coats the armor blank over the insulating conductive component to obtain an armored conductive component. The collection unit collects the armored conductive components. By sequentially extruding and coating the metal conductive core with an insulating layer and an armor layer, continuous production is achieved, improving the automation level of the production line.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figure 1 This utility model provides a conductive component production line, including a core material conveying unit 1, an extrusion coating unit 2, a continuous extrusion coating unit 3, an armor collection unit 4 arranged in sequence, and two armor blank conveying units 5 arranged in parallel, with the armor blank conveying units 5 located in front of the continuous extrusion coating unit 3.

[0015] The core material conveying unit 1 is used to convey the core material to the extrusion coating unit 2, which is used to extrude and coat the insulating layer onto the core material to obtain an insulating conductive component; the armor blank conveying unit 5 is used to convey the armor blank to the continuous extrusion coating unit 3, which is used to continuously extrude the armor blank and coat it over the insulating conductive component to obtain an armor conductive component; and the collection unit is used to collect the armor conductive component.

[0016] In this embodiment, by sequentially setting up extrusion coating unit 2 and continuous extrusion coating unit 3, an insulating layer and an armor layer are sequentially coated on the metal conductive core, thereby achieving continuous production and improving the automation level of the production line.

[0017] In some alternative embodiments, refer to Figure 1The continuous extrusion coating unit 3 includes a continuous extrusion coating mechanism 33, an armor cooling mechanism 32, an online diameter reduction mechanism 33, and an armor traction mechanism 34 arranged sequentially.

[0018] The continuous extrusion coating mechanism 33 is used to continuously extrude the armor blank to obtain the armor layer and suspend the insulating conductive component in the armor layer. The armor cooling mechanism 32 is used to cool the armor conductive component. The online diameter reduction mechanism 33 is used to cool the armor conductive component and reduce the diameter of the armor layer to bond the armor layer to the core material. The armor traction mechanism 34 is used to traction the armor conductive component after diameter reduction.

[0019] Furthermore, referring to Figure 2 The continuous extrusion coating mechanism 33 includes a continuous extruder and an extrusion die 311. The continuous extruder includes an extrusion roller and an extrusion roller shoe. The extrusion roller has an extrusion roller groove, and the extrusion roller and extrusion roller shoe form an extrusion cavity. The extrusion roller shoe has a die opening, and the extrusion roller shoe is connected to the extrusion die 311. The extrusion die 311 includes an inner die 3111 and an outer die 3112 fitted outside the inner die 3111. The inner die 3111 has a through hole 3114 at its center for the passage of an insulating conductive component, and the outer die 3112... An annular extrusion cavity 3113 is provided between the inner mold 3111 and the inner mold 3111. The inlet of the annular extrusion cavity 3113 is connected to the mold opening. There is a gap between the outlet of the annular extrusion cavity 3113 and the outlet of the through hole 3114. The outlet of the annular extrusion cavity 3113 is parallel to the outlet of the through hole 3114. The armored blank is transported to the extrusion wheel groove, enters the extrusion cavity, is continuously extruded, and passes through the annular extrusion cavity 3113 to obtain a closed annular armored layer. The insulating conductive component is suspended in the closed annular armored layer.

[0020] In this embodiment, the insulating conductive component enters the continuous extruder through the through hole 3114 in the center of the inner die 3111. The armored blank is continuously extruded into the extrusion cavity through the extrusion wheel groove, and then enters the annular extrusion cavity 3113 through the die opening. A closed annular armored layer is obtained through the annular extrusion cavity 3113. The insulating conductive component and the armored blank simultaneously enter the continuous extrusion coating mechanism 33, and the armored layer is obtained through continuous extrusion, realizing continuous production.

[0021] The insulating conductive component can be a metallic conductive component or an insulating conductive component covered with an insulating layer. In terms of material, the conductive component can be a copper conductive component, an aluminum conductive component, a silver conductive component, a steel conductive component, a copper alloy conductive component, an aluminum alloy conductive component, etc. In terms of shape, the conductive component can be a conductive rod or a conductive busbar. The armor layer has functions such as waterproofing, protection, and magnetic shielding. The armor layer can be an aluminum armor layer, a steel armor layer, etc. When the insulating conductive component is an insulating conductive component, because the armor layer is extruded at a high temperature through the annular extrusion cavity 3113, directly covering the insulating layer could easily burn it. In this embodiment, a gap is provided between the outlet of the annular extrusion cavity 3113 and the outlet of the through hole 3114, and the outlet of the annular extrusion cavity 3113 and the outlet of the through hole 3114 are parallel. Therefore, after the armor layer is extruded, it does not completely adhere to the insulating conductive component; the insulating conductive component is suspended within the closed annular armor layer, preventing the armor layer from contacting the insulating conductive component and burning the insulating layer.

[0022] After the armor layer and the insulating conductive component are cooled together in the armor cooling mechanism 32, the armor layer is then reduced in diameter by the online diameter reduction mechanism 33. After the armor layer is reduced in diameter, the thickness remains basically unchanged. The reduction in the outer diameter of the armor layer is converted into an increase in the length of the armor layer. After the outer diameter of the armor layer is reduced, the armor layer adheres to the insulating layer.

[0023] An armored traction mechanism 34 is set after the online diameter reduction mechanism 33. The armored traction mechanism 34 tightens the insulating conductive parts and continuously conveys the insulating conductive parts forward, ensuring that the insulating conductive parts move in a straight line and ensuring the concentricity of the insulating conductive parts.

[0024] Preferably, the extrusion roller has two parallel extrusion roller grooves, and the extrusion roller shoe has two die openings. The two die openings are respectively connected to the annular extrusion cavity 3113. The two armored billets enter one extrusion roller groove for continuous extrusion and are extruded into the annular extrusion cavity 3113 through one die opening.

[0025] Understandably, compared to a single armored blank, two armored blanks are more likely to form a closed ring after extrusion, reducing the product defect rate. The extrusion roller has two parallel extrusion grooves. The two armored blanks are extruded on one extrusion roller and then enter the annular extrusion chamber 3113 through the die openings on the extrusion shoe. This eliminates the need for two extrusion rollers to extrude the two armored blanks, reducing the space occupied by the continuous extrusion coating mechanism 33 and saving costs.

[0026] In some alternative embodiments, refer to Figure 3 The online diameter reduction mechanism 33 includes a diameter reduction mold 331, through which the armor layer is reduced in diameter and then bonded to the insulating conductive component.

[0027] In one specific embodiment, the diameter reduction mold 331 is provided with a diameter reduction channel 3311 for the armored conductive component to pass through. The diameter reduction channel 3311 includes an inlet and an outlet arranged opposite to each other. Along the direction from the inlet to the outlet, the inner diameter of the diameter reduction channel 3311 gradually decreases, and the diameter reduction mold 331 makes the armor layer fit tightly against the insulating conductive component.

[0028] In one specific embodiment, there are two or more diameter reduction dies 331, and the inner diameter of the diameter reduction channel 3311 of each diameter reduction die 331 gradually decreases along the transmission direction of the armor conductive component. Since heat is generated during the diameter reduction process of the armor layer, by setting two or more diameter reduction dies 331, multiple diameter reductions are performed separately to avoid excessively high temperatures causing grain growth, which would lead to a decrease in material strength and hardness.

[0029] Furthermore, the online diameter reduction mechanism 33 includes a cooling water tank 332, with the diameter reduction mold 331 located inside the cooling water tank 332. Coolant is placed inside the cooling water tank 332 to cool the diameter reduction mold 331. By setting up the cooling water tank 332, the coolant cools the armored conductive component, further preventing the material strength and hardness from decreasing due to excessively high temperatures during the diameter reduction process of the armor layer.

[0030] Furthermore, the online diameter reduction mechanism 33 also includes a clamping assembly 333 disposed in front of the cooling water tank 332. Since the insulating conductive component in the armored conductive component obtained by the armoring covering mechanism is suspended inside the armor layer, the armor layer is difficult to directly enter the diameter reduction die 331 at first. By setting the clamping assembly 333 in front of the cooling water tank 332, in actual production, a wire can be placed on the surface of the armor layer. The clamping assembly 333 includes octopus-shaped clamping claws that clamp the wire to the armor layer. The clamping assembly 333 cooperates with the rear traction mechanism, which pulls the wire, so that the armor layer can smoothly enter the drawing die at first.

[0031] In some alternative embodiments, refer to Figure 1 The continuous extrusion coating unit 3 also includes a self-adjusting guide mechanism 35, which is disposed between the armor cooling mechanism 32 and the online diameter reduction mechanism 33. The self-adjusting guide mechanism 35 is used to adjust the conveying speed of the cooled armor conductive parts.

[0032] Specifically, the self-adjusting guiding mechanism 35 includes a support frame, a lever arm, and a guide wheel. One end of the lever arm is rotatably connected to the support frame, and the other end of the lever arm is fixed to the guide wheel. The guide wheel has gravity, and under its own weight, it tends to move downwards. When the armored conductive wire is loose, the guide wheel moves downwards; when the armored conductive wire is tight, the guide wheel moves upwards. The self-adjusting guiding mechanism 35 then automatically adjusts the transmission speed according to the conveying speed of the armored conductive component. The large resistance of the diameter reduction mold 331 will affect the transmission speed of the armored conductive component. Therefore, setting up the self-adjusting guiding mechanism 35 before the online diameter reduction mechanism 33 can ensure the smooth operation of the production line.

[0033] In some alternative embodiments, refer to Figure 2 The armor blank conveying unit 5 includes an armor blank feeding mechanism 51, an armor blank traction mechanism 52, an armor blank straightening mechanism 53, and an armor blank cleaning mechanism 54 arranged in sequence. The armor blank feeding mechanism 51 is used to feed the wound armor blank, the armor blank traction mechanism 52 is used to traction the armor blank, the armor blank straightening mechanism 53 is used to straighten the traction armor blank, and the armor blank cleaning mechanism 54 is used to clean the straightened armor blank.

[0034] The armored billet feeding mechanism 51 includes a wire reel and a guide wheel assembly. The feeding mechanism continuously and stably releases the armored billet and adjusts the feeding tension through the guide wheel assembly to ensure the continuity of material supply and the accuracy of speed synchronization at the front end of the production line.

[0035] The armored billet traction mechanism 52 is a traction machine that provides the power for the armored billet to move forward.

[0036] The armor blank straightening mechanism 53 is a straightening machine, which includes a transverse straightening mechanism and a longitudinal straightening mechanism to ensure the straightness of the armor blank before it enters the continuous extrusion and coating mechanism 33.

[0037] The armor blank cleaning mechanism 54 includes one or more of a first cleaning component, a second cleaning component, and a third cleaning component. The first cleaning component is used to roughen the surface of the armor blank, which can remove stubborn stains and surface oxide scale. The second cleaning component smooths the surface of the armor blank, removing powder and solid particles. The smoothing process can also prevent solid particles from being stored in the pores or gaps of the rough surface, thus affecting the quality of the extruded material. The third cleaning component cleans the surface of the armor blank by using liquid to clean the surface of the armor blank.

[0038] The first cleaning component includes a first rotating brush and a second rotating brush located on both sides of the armor blank. The first rotating brush and the second rotating brush rotate around the armor blank, and at the same time, the first rotating brush and the second rotating brush can also rotate around their own rotation axis.

[0039] The second cleaning component includes a rotating disk, a brush holder, and a brush. The armor blank passes through the center of the rotating disk, which rotates around the armor blank. There are two or more brush holders, which are evenly distributed and fixed in the circumference of the rotating disk and rotate together with the rotating disk. The brush is fixed on the brush holder and performs rotating brushing on the armor blank.

[0040] The third cleaning component includes a water tank with an inlet for the armor blank to enter and an outlet for it to exit, located on the front and rear sides respectively. Multiple nozzles are arranged inside the water tank along the extension direction of the armor blank, and these nozzles spray water to clean the surface of the armor blank. Preferably, the third cleaning component is an ultrasonic water washing component.

[0041] Preferably, the armor blank cleaning mechanism 54 further includes a blowing assembly for blowing away powder or water. When the armor blank cleaning mechanism 54 includes two or more of a cleaning mechanism, a second cleaning assembly, and a third cleaning assembly, a blowing assembly can be provided after each cleaning mechanism.

[0042] Preferably, the armor blank cleaning mechanism 54 further includes a heating component, which is located after the blowing component. After the armor blank is heated, the metal plasticity is increased, the deformation resistance is reduced, thereby reducing the hardness requirement of the extrusion die material, increasing the deformation uniformity to facilitate filling the extrusion die and cavity, increasing the extrusion temperature to increase the solid solubility, and putting the material in a high-energy state, which is conducive to the precipitation of the second phase during subsequent aging. When the armor blank cleaning mechanism 54 is equipped with a third cleaning component, the heating mechanism is set to further remove the surface moisture of the armor blank, so as to prevent the undried moisture from being carried into the extruder and causing defects such as bulging due to evaporation of moisture into gas.

[0043] Preferably, the conductive component production line further includes a guiding integration mechanism 7, which is located after the armor blank cleaning mechanism 54. Alternatively, when the armor blank conveying mechanism further includes a blower mechanism, the guiding integration mechanism 7 is located after the blower mechanism. The guiding integration mechanism 7 guides the armor blank to the insulating conductive component line.

[0044] In some optional embodiments, the core material conveying unit 1 includes a core material feeding mechanism 11, a core material traction mechanism 12, a core material straightening mechanism 13, and a core material cleaning mechanism 14 arranged in sequence. The core material feeding mechanism 11 is used to feed the wound core material, the core material traction mechanism 12 is used to traction the core material, the core material straightening mechanism 13 is used to straighten the traction core material, and the core material cleaning mechanism 14 is used to clean the straightened core material.

[0045] The core material feeding mechanism 11 includes a wire reel and a guide wheel assembly. The feeding mechanism continuously and stably releases the core material and adjusts the feeding tension through the guide wheel assembly to ensure the continuity of material supply and the accuracy of speed synchronization at the front end of the production line.

[0046] The core material traction mechanism 12 is a traction machine that provides the power for the core material to move forward.

[0047] The core material straightening mechanism 13 is a straightening machine, which includes a transverse straightening mechanism and a longitudinal straightening mechanism to ensure the straightness of the core material before it enters the continuous extrusion and coating mechanism 33.

[0048] The core material cleaning mechanism 14 may also include one or more of the first cleaning component, the second cleaning component, and the third cleaning component, as well as a blowing component. The first cleaning component, the second cleaning component, the third cleaning component, and the blowing component are the same as those in the armor blank cleaning mechanism 54, and will not be described again here.

[0049] In some alternative embodiments, refer to Figure 1 The extrusion coating unit 2 includes a preheating mechanism 21, an extrusion coating mechanism 22, a post-heating mechanism 23, an insulation cooling mechanism 24, an insulation pre-traction mechanism 25, and an insulation detection mechanism (not shown in the figure), arranged in sequence.

[0050] The preheating mechanism 21 is used to preheat the core material, the extrusion coating mechanism 22 is used to extrude the insulating layer onto the core material to obtain an insulating conductive component, the post-heating mechanism 23 is used to heat the insulating conductive insulating layer, the insulation cooling mechanism 24 is used to cool the insulating conductive component, and the insulation pre-traction mechanism 25 is used to traction the cooled insulating conductive component.

[0051] It should be noted that in this embodiment, the metal conductive core pulled by the traction mechanism is heated by the preheating mechanism 21 and then enters the extrusion coating mechanism 22. At the same time, insulating particles are added into the extrusion coating mechanism 22. The extrusion coating mechanism 22 extrudes the insulating particles into an insulating layer and coats it on the metal conductive core to obtain an insulating conductive component. The insulating conductive component is pulled by the pre-insulation traction mechanism 25 and then heated by the post-heating mechanism 23 and cooled in the online cooling mechanism.

[0052] Insulation testing equipment includes one or more of the following: online power frequency spark test assembly, diameter measuring assembly, meter measuring assembly, visual inspection assembly, and thickness measuring assembly. The online power frequency spark test assembly tests whether the insulation layer of the insulating conductive component is leaking current. The diameter measuring assembly detects the outer diameter of the insulation layer in real time through laser diffraction or CCD imaging. The meter measuring assembly accurately measures the length of the insulating conductive component. The thickness measuring assembly is used to measure the thickness of the insulation layer, and its detection source can be ultrasound, X-ray, laser, current, etc. The visual inspection assembly is used to detect surface defects of the insulation layer.

[0053] Furthermore, both the core material traction mechanism 12 and the insulation front traction mechanism 25 are commercially available traction machines. The traction machine includes a pinch roller group, a drive system, and a control module. The metal conductive core or insulating conductive component is pinched between the rollers. The drive system controls the traction speed through the control module, which is synchronized with the rotation speed of the extrusion coating mechanism 22.

[0054] Furthermore, the extrusion coating mechanism 22 is a commercially available extrusion coating machine including components such as a hopper, screw, barrel, die head, and mold. The hopper is used to load the insulating plastic raw material. The screw, through rotation and propulsion, crushes, softens, melts, plasticizes, degasses, and compacts the plastic raw material within the barrel, continuously extruding the plasticized melt. The die head converts the rotating plastic melt into parallel linear motion, uniformly and smoothly guiding it into the die sleeve and applying the necessary molding pressure to the plastic. The mold includes an orifice and a core mold. The orifice forms the outer diameter of the insulating layer, and the core mold forms the inner diameter of the insulating layer. The core mold has a die hole in its center for the metal conductive core to pass through, thereby allowing the insulating layer to be coated onto the metal conductive core by the extrusion coating machine.

[0055] It is understood that in this embodiment, the metal conductive core is preheated by setting a preheating mechanism 21 so that the preheated metal conductive core can be tightly bonded to the extruded high-temperature insulation layer and can be produced continuously.

[0056] By setting the core material traction mechanism 12 and the insulation front traction mechanism 25 to form a closed-loop tension control, the synchronous error of the linear speed before and after the metal conductive core is covered with the insulation layer is reduced, ensuring the concentricity of the metal conductive core during forward conveying and preventing the problem of uneven thickness caused by eccentricity of the insulation layer.

[0057] Furthermore, the preheating mechanism 21 includes a metal tube coil and a temperature sensor (not shown in the figure).

[0058] The metal tube coil is composed of a spirally wound metal tube. The metal tube coil has a channel for the metal conductive core to pass through. When a high-frequency AC power is applied to the metal tube coil, the metal conductive core is heated by the cutting magnetic field passing through the channel. A temperature sensor is set on the outlet side of the channel to detect the temperature of the metal conductive core.

[0059] Understandably, when the metal conductive core passes through the preheating mechanism 21, its movement cuts the magnetic field, and the heat generated by the metal coil heats the metal conductive core. The preheating mechanism 21 does not heat the metal conductive core if it does not pass through, thus achieving online automatic heating. The temperature of the metal conductive core is monitored in real time by a temperature sensor, and based on the feedback temperature data, the heating of the metal conductive core to the preset temperature can be controlled.

[0060] Furthermore, the temperature sensor employs an infrared thermometer to detect the temperature of the preheated metal conductive core in a non-contact manner, thereby ensuring that the preheating requirements are met to adapt to the needs of subsequent coating processes.

[0061] Furthermore, the metal tube is a hollow tube with a coolant flow channel inside. The metal tube is also equipped with a coolant inlet and a coolant outlet that are respectively connected to the coolant flow channel. The coolant flows in the coolant flow channel to regulate the temperature of the metal tube.

[0062] Furthermore, the post-heating mechanism 23 can be an oven, which has openings at the front and back for the passage of insulating conductive components. The post-heating mechanism 23 is disposed between the extrusion coating mechanism 22 and the online cooling mechanism, and is used to heat the extruded insulating layer.

[0063] It is understandable that the extrusion coating mechanism 22 is prone to causing wrinkles and roughness on the surface of the insulation layer due to jamming during extrusion. By setting up the post-heating mechanism 23 to reheat and soften the insulation layer, the wrinkles are smoothed out, making the surface of the insulation layer smooth and improving the product yield.

[0064] In some alternative embodiments, refer to Figure 4 The conductive component production line also includes an insulation take-up and undo unit 6, which is located between the extrusion coating unit 2 and the continuous extrusion coating unit 3.

[0065] The insulation take-up and undo unit 6 includes an insulation take-up mechanism 61, an insulation undo mechanism 62, an insulation post-traction mechanism 63, an insulation straightening mechanism 64, and an insulation cleaning mechanism 65 arranged sequentially. The insulation take-up mechanism 61 is used to take up the cooled insulation conductive parts, the insulation undo mechanism 62 is used to undo the wound insulation conductive parts, the insulation post-traction mechanism 63 is used to traction the insulation conductive parts, the insulation straightening mechanism 64 is used to straighten the insulation conductive parts, and the insulation cleaning mechanism 65 cleans the surface of the straightened insulation conductive parts.

[0066] Specifically, the insulation cleaning mechanism 65 only includes the third cleaning component, which is the same as that in the armor blank cleaning mechanism 54, and will not be described again here.

[0067] It is understandable that this embodiment reduces the production length and saves floor space by setting up an insulated take-up and undo unit 6 to rewind the insulated conductive parts produced by the extrusion coating machine unit.

[0068] In some alternative embodiments, refer to Figure 1 The armor collection unit 4 includes an armor detection mechanism (not shown in the figure), which comprises one or more of the following: a diameter measuring component, a meter measuring component, a thickness measuring component, and a visual inspection component. The diameter measuring component detects the outer diameter of the armor layer in real time using laser diffraction or CCD imaging; the meter measuring component accurately measures the length of the armor conductive parts; the thickness measuring component measures the thickness of the armor layer, and its detection source can be ultrasound, X-ray, laser, current, etc.; the visual inspection component detects surface defects in the armor layer.

[0069] Following the armor inspection mechanism, there is also an armor winding mechanism 41 or an online sawing mechanism. The armor winding mechanism 41 is used to wind up the armor conductive parts, and the online sawing mechanism is used to saw and collect the armor layer.

[0070] Optionally, the armored collection unit 4 includes a guide wheel assembly mechanism and an armored winding mechanism 41. The guide wheel assembly mechanism includes multiple sets of guide wheels. The armored conductive components are guided by the guide wheels into the winding mechanism for winding, ensuring smooth winding. The armored winding mechanism 41 includes a reel and a reel lateral displacement drive. The reel moves back and forth in a lateral direction perpendicular to the movement direction of the armored conductive components to wind up the wire.

[0071] Optionally, the armored collection unit 4 includes an online sawing mechanism (not shown in the figure), a driving mechanism, and a collection mechanism. The driving mechanism drives the sawing machine to move in the direction of movement of the armored conductive parts. During the movement, the sawing mechanism completes the cutting of the armored conductive parts to a quantitative length, and the collection mechanism collects the cut armored conductive parts.

[0072] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
