DETAILED DESCRIPTION
[0045] The following is combined with Figure 1-7 , further details of this application are given.
[0046] Example:
[0047] The embodiment of the present application discloses a PEEK insulated wire processing technology.
[0048] Reference Figure 1-2 , a PEEK insulated wire processing process, comprising the following steps:
[0049] Preparation of PEEK material: Since the processing of PEEK requires the purity and cleanliness of the material and cannot be damp, otherwise it will affect the processing process, coating structure and product performance, the PEEK material needs to be baked at a temperature of 100-150°C for more than 8 hours before processing to ensure that the moisture is completely removed. In this embodiment, the PEEK material can be any one of polyaryletherketone (PAEK), polyetherketone (PEK), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), polyetheretherketoneketone (PEEKK), polyetherketoneetherketoneketone (PEKEKK), polyaryletherketone and fluorinated polyetheretherketone (FPEEK).
[0050] Paying off the wire: Controlling the core wire to be routed at an appropriate tension value. In this embodiment, the material of the core wire can be a highly conductive metal such as pure copper, pure aluminum, copper-silver alloy, etc.
[0051] Preheating: Before the core wire comes into contact with the PEEK material, the core wire is preheated by vacuum induction heating; compared with traditional open resistance heating, the heating efficiency is higher and the heating is more uniform; in addition, the above heat treatment can also improve the bonding performance of the core wire through the orientation symmetry between the grains.
[0052] Plasma cleaning: The core wire is plasma cleaned by direct atmospheric plasma cleaning agent; after plasma cleaning, the surface of the core wire is slightly corroded, the contact angle is significantly reduced, and the surface roughness is significantly improved, which is conducive to improving the bonding force with the PEEK material, thereby improving the adhesion of the PEEK material on the core wire, reducing the possibility of local powdering and brittle cracking on the surface of the PEEK insulated wire, and increasing the service life of the PEEK insulated wire.
[0053] Extrusion coating: According to the specifications of the PEEK insulated wire to be produced, an appropriate die is installed on the head of the extruder, and the PEEK material is extruded by vacuum. In order to further improve the tightness of the combination of the PEEK material and the core wire and improve the surface flatness of the PEEK insulated wire, an extrusion die is used.
[0054] Cooling: When the ambient temperature is below the specified temperature, the PEEK insulated wire is directly air-cooled after coming out of the mold; when the ambient temperature is greater than the specified temperature, air cooling and / or water cooling are used for cooling.
[0055] Online detection: The eccentricity of the paint film on the PEEK insulation wire is detected online by using the eccentricity detection device 2, so as to adjust the eccentricity of the paint film in time and improve the quality of the finished product of the PEEK insulation wire.
[0056] Wire collection: The wire collection device is used to store and collect the PEEK insulated wire.
[0057] In the above-mentioned pay-out step, the raw material of the core wire can be one of round conductors, extruded flat conductors or molded soft flat conductors. If the raw material of the core wire is a molded soft flat conductor, the core wire is directly preheated after pay-out; if the raw material of the core wire is a round conductor, before preheating, it needs to go through round drawing, calendering and flat drawing steps in sequence; if the raw material of the core wire is an extruded flat conductor, before preheating, it needs to go through a flat drawing step. And if the raw material of the core wire is a round conductor or an extruded flat conductor, after the flat drawing is completed, it is cleaned with an ultrasonic cleaner to remove stains on its surface, and after cleaning, it is blown dry and / or dried. After the surface is dry, it is annealed. In this embodiment, the annealing treatment is performed by induction heating, and nitrogen is used in the heating furnace to protect the metal wire to achieve the purpose of softening the metal wire, thereby reducing its hardness and improving its plasticity, so as to facilitate processing and ensure processing quality.
[0058] Reference Figure 1 and Figure 3 In the above extrusion coating step, before the core wire enters the extruder, the line position of the core wire is adjusted by the eccentricity adjustment device 1 to ensure that the core wire is always at the extrusion center of the mold, so as to reduce the eccentricity of the paint film.
[0059] Reference Figure 2 and Figure 4 The eccentricity detection device 2 includes a fixed frame 21 through which the PEEK insulating wire can pass. An upper paint film thickness gauge 22, a lower paint film thickness gauge 23, a left paint film thickness gauge 23 and a right paint film thickness gauge 25 are respectively provided on the upper, lower, left and right sides of the inner circumference of the fixed frame 21. The upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 are located on the same vertical plane and are respectively used to measure the paint film thickness on the upper, lower, left and right sides of the same cross section of the PEEK insulating wire, so as to facilitate online measurement of the eccentricity of the PEEK insulating wire, so that the operator can adjust the eccentricity in time to ensure the production quality of the PEEK insulating wire.
[0060] Reference Figure 4 The upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 are all fixedly connected with a sliding rod 26, each sliding rod 26 is slidably arranged on the fixed frame 21, and the front and rear sides of the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 are all provided with abutment wheels 27 for abutting against the PEEK insulating wire, each abutment wheel 27 is connected to the sliding rod 26 on the corresponding side through a connecting frame 28, and each sliding rod 26 is locked on the fixed frame 21 through a locking member 29. In this way, on the one hand, the PEEK insulating wire is limited to the fixed frame 21 by the abutment wheels 27 on the four sides, which is convenient for guiding the routing of the PEEK insulating wire. Secondly, through the above structure, no matter what changes occur in the specifications and dimensions of the PEEK insulated wire, the distances between the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 and the corresponding paint film surface on the same side can always be kept consistent, thereby ensuring the consistency of the measurement distances of the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25, thereby ensuring the accuracy of the measurement results.
[0061] Reference Figure 3 and Figure 5 The eccentricity adjustment device 1 includes a base frame 11, a left limiting roller 111 and a right limiting roller 112 for limiting the core wire to the left and right, and an upper limiting roller 113 and a lower limiting roller 114 for limiting the core wire to the upper and lower positions. The distance between the left limiting roller 111 and the right limiting roller 112 can be adjusted, and the distance between the upper limiting roller 113 and the lower limiting roller 114 can be adjusted.
[0062] A horizontal moving unit 12 and a first driving member 121 for driving the horizontal moving unit 12 to move along the width direction of the base frame 11 are provided on the base frame 11, and a left limiting roller 111 and a right limiting roller 112 are provided on the horizontal moving unit 12; a vertical moving unit 13 and a second driving member 131 for driving the vertical moving unit 13 to move up and down are provided on the base frame 11, and an upper limiting roller 113 and a lower limiting roller 114 are provided on the vertical moving unit 13.
[0063] Reference Figure 4-6 The eccentricity adjustment device 1 further includes a processor 14, and the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24, the right paint film thickness gauge 25, the first driving member 121 and the second driving member 131 are respectively connected to the processor 14 by signals. In this embodiment, the first driving member 121 is an electric push rod, and the second driving member 131 is a screw module.
[0064] The steps of using the eccentricity adjusting device 1 are as follows:
[0065] S1, according to the cross-sectional dimensions of the PEEK insulated wire, adjust each sliding rod 26 so that the four sides of the PEEK insulated wire are respectively in contact with the corresponding abutment wheel 27, and keep the PEEK insulated wire located at the center of the fixed frame 21, lock each sliding rod 27;
[0066] S2, the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 simultaneously measure the thickness of the paint film corresponding to the four sides of the PEEK insulated wire, the thickness value measured by the upper paint film thickness gauge 22 is a, the thickness value measured by the lower paint film thickness gauge 23 is b, the thickness value measured by the left paint film thickness gauge 24 is c, and the thickness value measured by the right paint film thickness gauge 25 is d;
[0067] S3, the upper paint film thickness gauge 22, the lower paint film thickness gauge 23, the left paint film thickness gauge 24 and the right paint film thickness gauge 25 transmit the measured thickness values a, b, c, d signals to the processor 14 respectively;
[0068] S4, the processor 14 calculates the required displacement H of the vertical moving unit 13 according to the formula H=p·(ab) / 2, calculates the required displacement X of the horizontal moving unit 12 according to the formula X=p·(cd) / 2, and transmits the values X and H to the first driving member 121 and the second driving member 131 respectively;
[0069] S5. When H<0, the first driving member 121 drives the vertical moving unit 13 to move downward. When H=0, the vertical moving unit 13 remains in place. When H>0, the first driving member 121 drives the vertical moving unit 13 to move upward. The moving distance is p·|(ab) / 2|.
[0070] When X<0, the second driving member 131 drives the horizontal moving unit 12 to move rightward. When X=0, the horizontal moving unit 12 keeps its original position. When X>0, the second driving member 131 drives the horizontal moving unit 12 to move leftward. The moving distance is p·|(cd) / 2|.
[0071] The position point of the die mouth of the extrusion die is set to A, the position point of the eccentricity detection device is set to B, the position point of the eccentricity adjustment device is set to C, the distance between B and A along the core wire routing direction is s, and the distance between B and C along the core wire routing direction is t. Since the extrusion die, the fixed frame 21 of the eccentricity detection device 2, and the base frame 11 of the eccentricity adjustment device 1 remain fixed during the production process of the PEEK insulated wire, and since the extrusion die is located between the eccentricity detection device and the eccentricity adjustment device, t / s is a constant greater than 1.
[0072] Reference Figure 7 , taking the eccentricity adjustment device for adjusting the eccentricity in the vertical direction as an example, the displacement of the core wire at the die mouth of the extrusion die is △H, which can be deduced from the inference of similar triangles, |H| / △H=t / s, and △H=|(cd) / 2|, so |H|=p·|(ab) / 2|, where p=t / s, is an adjustment coefficient greater than 1. Similarly, it can be deduced that |X|=p·|(cd) / 2|, where p=t / s, is an adjustment coefficient greater than 1.
[0073] In this way, by measuring the thickness of the paint film of the PEEK insulated wire on the four sides of the top, bottom, left and right, and transmitting the measured data to the processor 14, the processor 14 calculates the displacement required for the core wire correction, and transmits the displacement data to the first drive member 121 and the second drive member 131. The first drive member 121 drives the vertical moving unit 13 to move up or down, and the second drive member 131 drives the horizontal moving unit 12 to move left or right, thereby adjusting the running position of the core wire in real time to ensure that the core wire is always in the extrusion center of the mold, thereby reducing the eccentricity of the paint film.
[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
