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 the battery pack and generator, as well as to charge the battery pack. Current generation conductive components consist of a core material and an insulating layer covering it; the insulating layer blocks current.

[0003] Existing technology first prepares the core material separately, and then covers the core material with an insulating layer. The continuously extruded products need to be transported to the extrusion line after continuous extrusion. The billet needs to be produced independently through two production lines. The entire preparation process has low production efficiency and high labor and energy costs. During the transportation of continuously extruded products, defects may occur due to collision, oxidation or contamination. Utility Model Content

The front traction mechanism pulls the cooled metal conductive core, the extrusion coating mechanism is used to extrude an insulating layer onto the metal conductive core to obtain an insulating conductive component, the second online cooling mechanism is used to cool the insulating conductive component, and the rear traction mechanism pulls the cooled insulating conductive component.

Detailed Implementation

[0016] 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.

[0017] Reference Figure 1 This utility model provides a conductive component production line, including a continuous extrusion unit 2 and an extrusion coating unit 3 arranged in sequence.

[0018] The continuous extrusion unit 2 includes a continuous extrusion mechanism 21 and a first online cooling mechanism 22 arranged in sequence. The continuous extrusion mechanism 21 is used to continuously extrude the metal billet to obtain a metal conductive core, and the first online cooling mechanism 22 is used to cool the metal conductive core.

[0019] The extrusion coating unit 3 includes a front traction mechanism 31, an extrusion coating mechanism 35, a second online cooling mechanism 37, and a rear traction mechanism 38 arranged in sequence. The front traction mechanism 31 pulls the cooled metal conductive core, the extrusion coating mechanism 35 is used to extrude the insulating layer onto the metal conductive core to obtain an insulating conductive component, the second online cooling mechanism 37 is used to cool the insulating conductive component, and the rear traction mechanism 38 pulls the cooled insulating conductive component.

[0020] It is understandable that the conductive component production line in this embodiment is designed with integration. The metal billet passes through the continuous extrusion unit 2 and the extrusion coating unit 3 continuously to achieve continuous production and improve production efficiency. After continuous extrusion and cooling, the metal billet can be coated with an insulating layer. The continuously extruded products can directly enter the next process, reducing human intervention and damage risks and improving the yield rate.

[0021] Specifically, a continuous extrusion press is a commercially available continuous extrusion press that includes components such as an extrusion roller, a compaction roller, an extrusion shoe, a plug, and an extrusion die. The extrusion roller has grooves on its circumference to accommodate and transport the metal billet to be extruded. The compaction roller is located on the feed side of the extrusion roller and is used to initially compact and guide the metal billet. The extrusion shoe cooperates with the extrusion roller to form an extrusion cavity, and a groove sealing block is installed on the extrusion shoe to close the concave grooves of the extrusion roller. The plug is fixed to the outlet end of the extrusion cavity to prevent the metal billet from continuing to move forward, forcing it to flow out of the extrusion die. The extrusion die is fixed to the extrusion shoe and can include round bar dies or flat bar dies, etc., to prepare conductive components of different shapes.

[0022] The first online cooling mechanism 22 includes a first cooling water tank and a first air-cooling component disposed after the first cooling water tank. The coolant in the first cooling water tank cools the metal conductive core, and the first air-cooling component dries the liquid residue on the surface of the metal conductive core.

[0023] The second online cooling mechanism 37 includes a second cooling water tank and a second air-cooling assembly disposed after the second cooling water tank. Further, a support roller is disposed within the second cooling water tank, and an insulated conductive component is transmitted forward from the support roller. A gap exists between the second cooling water tank and the extrusion coating mechanism 35.

[0024] It is understandable that, to improve the bonding strength between the insulation layer and the metal conductive core, the cooling rate of the insulation layer should be reduced, and the bonding time between the insulation layer and the conductive core should be extended. In this embodiment, there is a gap between the second cooling water tank and the extrusion coating mechanism 35, so the insulating conductive component is transported forward in the air and first cooled by air; a support roller is set inside the second cooling water tank, and the insulating conductive component moves on the support roller, and finally the insulating conductive component is cooled by the air cooling assembly. By setting gradient cooling, the cooling rate of the insulation layer is reduced, and the bonding strength between the insulation layer and the metal conductive core is improved.

[0025] Specifically, the insulating conductive component can be located above or below the coolant level in the second cooling water tank. When the insulating conductive component is below the coolant level in the second cooling water tank, cooling time is saved and the production line length is reduced. When the insulating conductive component is above the coolant level in the second cooling water tank, the insulating conductive component is not immersed in the coolant, which reduces the cooling rate and improves the bonding strength.

[0026] It should be noted that both the front traction mechanism 31 and the rear traction mechanism 38 are commercially available traction machines. The traction machine includes a pinch roller assembly, a drive system, and a control module. The metal conductive core or insulating conductive component is pinched and fed between the rollers. The drive system controls the traction speed through the control module, synchronizing it with the rotational speed of the extrusion coating mechanism 35. By setting the front traction mechanism 31 and the rear traction mechanism 38 in a linked manner to form a closed-loop tension control, the synchronization error of the linear speed before and after the metal conductive core is coated with the insulating layer is reduced, ensuring the concentricity of the metal conductive core during forward conveying and preventing uneven thickness caused by eccentricity of the coating insulating layer.

[0027] The extrusion coating mechanism 35 is a commercially available extrusion coating machine that includes 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. 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. The core mold has a central hole for a metal conductive core to pass through, thus allowing the insulating layer to coat the metal conductive core via the extrusion coating machine.

[0028] In some alternative embodiments, refer to Figure 2The conductive component production line also includes a self-adjusting guide mechanism 4, which is located between the continuous extrusion unit 2 and the extrusion coating unit 3. The self-adjusting guide mechanism 4 is used to adjust the conveying speed of the cooled metal conductive core.

[0029] Specifically, the self-adjusting guiding mechanism 4 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 is subject to gravity, and under its own weight, it tends to move downwards. When the metal conductive core transmission line is loose, the guide wheel moves downwards; when the metal conductive core transmission line is tight, the guide wheel moves upwards. The self-adjusting guiding mechanism 4 then automatically adjusts the transmission speed according to the conveying speed of the metal conductive core. The self-adjusting guiding mechanism 4, installed between the continuous extrusion unit 2 and the extrusion coating unit 3, ensures the smooth operation of the production line.

[0030] In some alternative embodiments, refer to Figure 2 The extrusion coating unit 3 also includes a core material straightening mechanism 32, a core material cleaning mechanism 33, a front traction mechanism 31, a core material straightening mechanism 32, a core material cleaning mechanism 33, and an extrusion coating mechanism 35 arranged in sequence.

[0031] Specifically, the core material straightening mechanism 32 is a straightening machine, which includes a transverse straightening unit and a longitudinal straightening unit to eliminate the bending stress of the metal conductive core and avoid uneven thickness of the covering insulation layer.

[0032] The core material cleaning mechanism 33 includes a water cleaning component, which comprises a water tank. The water tank has an inlet on its front side and an outlet on its back side for the metal conductive core to enter. Multiple annular nozzles are arranged inside the water tank along the extension direction of the metal conductive core. These annular nozzles are mounted on a support member, which has an inlet pipe connected to the annular nozzles. The metal conductive core passes through the annular nozzles, which spray water onto its circumferential surface for cleaning. Preferably, the support member is an ultrasonic vibration support member, allowing the core material cleaning mechanism 33 to perform online ultrasonic cleaning of the metal conductive core, thus improving the cleaning effect.

[0033] Preferably, the core cleaning mechanism 33 further includes a blower assembly, which is positioned after the water cleaning assembly to blow away residual water on the surface of the metal conductive core.

[0034] In some alternative embodiments, refer to Figure 1 The extrusion coating unit 3 also includes a front heating mechanism 34, which is disposed between the core material cleaning mechanism 33 and the extrusion coating mechanism 35. The front heating mechanism 34 is used to preheat the cleaned metal conductive core.

[0035] It should be noted that the preheating mechanism 34 preheats the metal conductive core to ensure a tight bond between the preheated metal conductive core and the extruded high-temperature insulation layer, enabling continuous production. The preheating mechanism 34 can be a resistance furnace heating mechanism, an electromagnetic induction heating mechanism, an infrared heating mechanism, etc. In the resistance furnace heating mechanism, current passes through the resistance heating element (such as heating wire, silicon carbide rod, silicon molybdenum rod, etc.) in the furnace to generate heat, which indirectly heats the metal conductive core in the furnace through thermal radiation and thermal convection. The electromagnetic induction heating mechanism uses an alternating magnetic field to generate eddy currents and hysteresis losses inside the metal for heating. The infrared heating mechanism uses an infrared radiator to emit infrared rays of a specific wavelength, which are absorbed by the metal conductive core and converted into heat energy.

[0036] In one specific embodiment, the front heating mechanism 34 includes a metal tube coil and a temperature sensor. The metal tube coil is composed of a spirally wound metal tube, and a channel is provided inside the metal tube coil for the passage of a metal conductive core. When a high-frequency AC power is applied to the metal tube coil, the metal conductive core is heated by passing through the channel and a cutting magnetic field. The temperature sensor is located on the outlet side of the channel and is used to detect the temperature of the metal conductive core.

[0037] Understandably, when the metal conductive core passes through the pre-heating mechanism 34, its movement cuts the magnetic field, and the metal coil generates heat to heat the metal conductive core. The metal conductive core is not heated if it does not pass through the pre-heating mechanism 34, 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 a preset temperature can be controlled.

[0038] 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.

[0039] 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.

[0040] In some alternative embodiments, refer to Figure 1 The extrusion coating unit 3 also includes a post-heating mechanism 36, which is disposed between the extrusion coating mechanism 35 and the second online cooling mechanism 37. The post-heating mechanism 36 is used to heat the insulating layer of the insulating conductive component.

[0041] It is understandable that the extrusion coating mechanism 35 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 36 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.

[0042] Specifically, the front heating mechanism 34 can also be a resistance furnace heating mechanism, an electromagnetic induction heating mechanism, an infrared heating mechanism, etc. Preferably, the rear heating mechanism 36 can be an oven, which has openings at the front and rear for the passage of insulating conductive parts.

[0043] In some alternative embodiments, refer to Figure 1 The conductive component production line also includes a billet conveying unit 1, which is located before the continuous extrusion unit 2. The billet conveying unit 1 includes a billet feeding mechanism 11, a billet traction mechanism 12, a billet straightening mechanism 13, and a billet cleaning mechanism 14 arranged in sequence.

[0044] Specifically, the billet feeding mechanism 11 includes a wire reel and a guide wheel assembly. The billet feeding mechanism 11 continuously and stably releases metal billets 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.

[0045] The billet traction mechanism 12 can also be a traction machine, which includes a pinch roller group, a drive system and a control module. The metal billet is pinched between the rollers, and the drive system controls the traction speed through the control module to synchronize with the speed of the continuous extrusion press.

[0046] The billet straightening mechanism 13 is a straightening machine, which includes a transverse straightening unit and a longitudinal straightening unit to eliminate the bending stress of the metal billet.

[0047] Furthermore, the blank cleaning mechanism 14 includes one or more of the following: a wheel brush cleaning assembly, a brush cleaning assembly, and a water rinsing assembly.

[0048] Specifically, the wheel brush cleaning assembly includes a first rotating roller brush and a second rotating roller brush located on both sides of the metal blank. The first rotating roller brush and the second rotating roller brush rotate around the metal blank. At the same time, the first rotating roller brush and the second rotating roller brush can also rotate around their own rotation axis.

[0049] The brush cleaning assembly includes a rotating disk, a brush holder, and a brush. A metal blank passes through the center of the rotating disk, which rotates around the metal blank. There are two or more brush holders, which are evenly distributed and fixed around the circumference of the rotating disk and rotate together with the rotating disk. The brush is fixed on the brush holder and performs a rotating brushing motion on the metal blank.

[0050] The water cleaning assembly includes a water tank with an inlet for the metal billet to enter and an outlet for it to exit, located on its front and rear sides respectively. Multiple annular nozzles are arranged inside the water tank along the extension direction of the metal billet. These nozzles are mounted on a support member, which contains a water inlet pipe. The annular nozzles are connected to the water inlet pipe. The metal billet passes through the annular nozzles, which spray water onto its circumferential surface for cleaning. Preferably, the support member is an ultrasonic vibration support member, and the billet cleaning mechanism 14 performs online ultrasonic cleaning on the metal billet, improving the cleaning effect.

[0051] Preferably, the blank cleaning mechanism 14 further includes a blowing assembly for blowing away powder or water. When the blank cleaning mechanism 14 includes two or more of the following: a roller brush cleaning assembly, a brush cleaning assembly, and a water rinsing assembly, a blowing assembly can be provided after each cleaning assembly.

[0052] In some alternative embodiments, refer to Figure 1 The billet conveying unit 1 also includes a billet heating mechanism 15, which is located after the billet cleaning mechanism 14. The billet heating mechanism 15 is the same as the previous heating mechanism 34, and will not be described again here.

[0053] It is understandable that heating the metal billet increases its plasticity, reduces its deformation resistance, thereby lowering the hardness requirements of the extrusion die material, increases the uniformity of deformation to facilitate filling the extrusion die and cavity, increases the extrusion temperature to increase the solid solubility, and puts the material in a high-energy state, which is beneficial for the subsequent aging process to fully precipitate the second phase. When the billet cleaning mechanism 14 is equipped with a water cleaning component, a heating mechanism is set up to further remove the moisture on the surface of the metal billet, preventing the undried moisture from being carried into the extruder and causing defects such as bulging due to evaporation of the moisture into gas.

[0054] In some optional embodiments, the continuous extrusion unit 2 further includes a core material detection mechanism (not shown in the figure), which is disposed after the first online cooling mechanism 22. The core material detection mechanism includes one or more of a diameter gauge, a meter counter, and a visual inspection instrument.

[0055] It should be noted that the diameter gauge is used to measure the diameter of the metal conductive core, the meter counter is used to measure the length of the metal conductive core, and the visual inspection instrument is used to detect surface defects in the metal conductive core. Specifically, the diameter gauge detects the outer diameter of the metal conductive core in real time through laser diffraction or CCD imaging.

[0056] In some optional embodiments, the extrusion coating unit 3 further includes an insulation testing mechanism (not shown in the figure), which is located after the rear traction mechanism 38. The insulation testing mechanism includes one or more of an online power frequency spark tester, a diameter gauge, a meter counter, a visual inspection instrument, and a thickness gauge.

[0057] It should be noted that the online power frequency spark tester tests whether the insulation layer of the insulating conductive component is leaking current; the diameter gauge detects the outer diameter of the insulation layer in real time through laser diffraction or CCD imaging; the meter counter accurately measures the length of the insulating conductive component; the thickness gauge is used to measure the thickness of the insulation layer, and its detection source can be ultrasound, X-ray, laser, current, etc.; and the visual inspection instrument is used to detect surface defects of the insulation layer.

[0058] In some alternative embodiments, refer to Figure 1 The extrusion coating unit 3 also includes a winding mechanism 39, which is located after the rear traction mechanism 38.

[0059] Specifically, the winding mechanism 39 includes a guide wheel assembly and a winding assembly. The guide wheel assembly includes multiple sets of guide wheels, through which the insulating conductive component is guided into the winding assembly for winding, ensuring smooth winding. The winding assembly includes a reel and a reel lateral displacement drive, which moves back and forth in a lateral direction perpendicular to the direction of movement of the insulating conductive component to wind up the wire.

[0060] In some optional embodiments, the extrusion coating unit 3 also includes an online sawing mechanism (not shown) disposed after the rear traction mechanism 38.

[0061] Specifically, the online sawing mechanism includes a sawing component, a driving component, and a collecting component. The driving component drives the sawing component to move in the direction of movement of the insulating conductive component. During the movement, the sawing component completes the cutting of the insulating conductive component to a quantitative length, and the collecting component collects the cut insulating conductive component.

[0062] 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.
