All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 and 2 together, an embodiment of the present invention provides a wire rod pretreatment method. It will be understood that the order of the steps in the flow diagrams may be changed and certain steps may be omitted, depending on various requirements. The wire rod pretreatment method comprises the following steps:
s1: providing a wire 10, and cutting the wire 10 according to a preset length.
It is understood that the wire 10 is an insulated magnet wire used to manufacture coils or windings in electrical products. The electromagnetic wire comprises an enameled wire, a lapped wire and the like. In this embodiment, the wire 10 is an enameled wire, and includes a conductor 101 and an insulating layer 102. The insulating layer 102 covers the conductor 101. The conductor 101 may be a metal conductor, such as copper wire, aluminum wire, or the like. The insulating layer 102 may be an insulating material such as insulating varnish, insulating plastic, insulating resin, or insulating silicone rubber. In this embodiment, the conductor 101 of the wire 10 is a wire formed by twisting a plurality of copper wires, and the insulating layer 102 is an insulating plastic.
It can be understood that the preset length refers to the length of the wire rod required for winding the coil, and the specific length can be adjusted according to actual needs.
It can be understood that the cutting process can be automatically cut by a cutting machine, and can also be manually cut.
S2: the insulating layers at both ends of the wire 10 are removed to expose a portion of the conductor 101.
It can be understood that after the insulation layers at the two ends of the cut wire 10 are removed, the two ends of the wire 10 are exposed to the conductor 101. The exposed conductor 101 can be used to connect two ends of the wire 10 with other electronic components.
It is understood that in the present embodiment, the insulating layer 102 is insulating plastic. When the insulation layer 102 is automatically removed by a machine, the insulation layer 102 at a predetermined position of the wire 10 may be cut by the machine to expose portions of the conductors 101 at both ends of the wire 10. When the insulating layer 102 is manually removed, the insulating layer 102 may be punctured at a predetermined position at two ends of the wire 10, and then a diluent is adhered at the corresponding punctured position, so that the insulating layer 102 at two ends of the wire 10 is manually pulled off to expose a portion of the conductor 101.
It is understood that the specific method for removing the insulating layer 102 can be adjusted according to different wires and different environmental conditions, and the method for removing the insulating layer 102 is not limited in the present invention.
It is understood that after the insulating layer 102 is removed from both ends of the wire 10, the ends 11 are formed on both ends of the wire 10. The end portion 11 is an end of the wire 10 close to the exposed conductor 101, and the insulating layer 102 is disposed on the end portion 11.
It is understood that the preset length includes a length of the conductor 101 where both ends of the wire 10 are exposed.
S3: the end 11 of the wire 10 near the exposed conductor 101 is encapsulated.
It is understood that when the exposed conductor 101 is soldered to other electronic components, the wire 10 is easily damaged by high temperature soldering. For example, damage to the insulation layer 102 of the wire 10, resulting in wire leakage, greatly increasing the safety risk of the wire 10. Therefore, an encapsulation process is also performed at a position where the wire 10 is close to the exposed conductor 101, that is, the end portion 11, to protect the wire 10.
It is understood that the encapsulation process means coating the wire 10 with an insulating high temperature resistant material.
In this embodiment, the encapsulation process is completed by coating the insulating layer 102 of the end portion 11 with a glass cloth tape.
It is understood that the glass cloth tape refers to a high temperature resistant material formed by covering the surface of a fabric woven by glass fibers with high performance silica gel. The glass cloth adhesive tape has the characteristics of good temperature resistance, strong adhesion force, toughness, tearing resistance and the like, and can be applied to various high-strength insulation protection scenes such as heat-resistant insulation binding, high-temperature protection and the like.
It is understood that in other embodiments, the wire 10 may be encapsulated by other insulating and high temperature resistant materials, such as teflon high temperature tape, high temperature PET green tape, polyimide high temperature tape, etc., and the invention is not limited to the encapsulating material.
It will be appreciated that the wire 10 may be encapsulated by machine or manually.
S4: the exposed conductor 101 is subjected to solder molding.
It can be understood that the conductor 101 is formed by polymerizing a plurality of strands of copper wires, and when the wire 10 is cut and the insulating layer 102 is removed, the conductor 101 of the wire 10 is prone to have the copper wires scattered, which is not favorable for the connection of the exposed conductor 101 with other electronic components. Therefore, the exposed conductor 101 is subjected to a solder molding process to facilitate a further connection operation of the wire 10. The soldering forming process is to polymerize the exposed copper wires scattered from the conductor 101 into a strand of conducting wire by soldering.
It is to be understood that the soldering process may be performed by a mold or may be performed manually.
It is understood that the wire 10 processed in the above steps S1 to S4 can be used for coil winding on the corresponding magnetic core.
It can be understood that the ends of the coil formed by winding the wire 10 are two ends of the wire 10 which are subjected to the encapsulation process and the soldering forming process.
It is understood that the ends of the wire 10 are exposed when the coil is wound.
It can be understood that the coil can be manually wound, and the coil can also be wound by an automatic winding machine.
It can be understood that automatic coil winding machine efficiency is higher, can accomplish the winding displacement automatically, compares in artifical manual coiling, and it is bigger to accomplish in batches, and production is more efficient stable.
It is understood that all or part of the steps of the wire rod pre-treatment method may be performed on one machine.
It is understood that in other embodiments, the encapsulation process may be performed on the predetermined position of the wire 10, and then the cutting and soldering processes may be performed.
It is understood that the wire 10 pretreated through the above steps S1 to S4 may be used to wind a transformer coil, an inductor coil, or the like.
It is understood that in other embodiments, the step S4 in the preprocessing method can be omitted, and the exposed conductors 101 at the two ends of the wire 10 can be directly connected to other electronic components after winding the wire 10 processed in the steps S1 to S3.
The wire rod pretreatment method provided by the invention can be understood to solve the defects of the existing coil winding method by cutting, encapsulating and soldering tin forming the wire rod in advance, thereby effectively improving the generation efficiency and improving the yield of the coil.
It should be emphasized that the above-described embodiments are merely preferred embodiments of the invention, rather than limiting in any way, and that any simple modifications, equivalent variations or modifications made to the above-described embodiments, based on the technical spirit of the invention, are intended to be included within the scope of the present invention.
