Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1 to 4, an embodiment of a manufacturing process of a driving coil according to the present invention includes the steps of:
s1, coating epoxy glue on the surface of the bare wire 31 to form an epoxy glue layer 32;
s2, winding a coating tape on the surface of the epoxy glue layer 32 to form a coating layer 33; thereby preparing the covered wire 3;
s3, winding the covered wire 3 on the surface of the first armor plate 1;
s4, coating the covered wire 3 with the second armor 2;
s5, after the winding is finished, placing the coil in a constant temperature environment of 200-250 ℃, keeping 50-70min for baking and curing to prepare the driving coil, and then testing the driving coil to judge whether the overall lapping and shearing strength of the driving coil is above 32 Mpa.
The time interval between the step S1 and the step S2 is short in the present application, and therefore when the prepared covered wire 3 is wound on the surface of the first armor 1, since the covered wire 3 is subjected to the pressure of the adjacent covered wire 3, the epoxy glue applied to the bare wire 31 can seep out through the covering layer 33, thereby increasing the adhesiveness when the adjacent covered wire 3 is wound. Meanwhile, the extruded epoxy glue can flow to the joint of the covered wire 3 and the first armor 1 and the joint of the second armor 2, so that the connection tightness of the covered wire 3 and the first armor 1 and the second armor 2 is increased. In addition, after the epoxy glue coated on the bare wires 31 seeps out through the coating layer 33, the wettability between the epoxy glue layer 32 and the coating layer 33 can be improved, so that no layering phenomenon exists between the bare wires 31 and the epoxy glue layer 32 and between the bare wires 31 and the coating layer 33, the heat-conducting property of the driving coil is improved, and the stability of the performance of the driving coil in use is ensured.
In step S3, the surface of the first armor 1 is coated with epoxy glue, and the epoxy glue coated on the surface of the first armor 1 can better wet with the coating 33 outside the covered wire 3, so as to increase the firmness of the covered wire 3 wound on the first armor 1. Simultaneously, the epoxy glue of coating on first armour 1 surface also can fuse with the epoxy glue that is extruded in the epoxy glue film 32 to can further increase the stability that envelope curve 3 and first armour 1 are connected.
In step S4, the wrapped covered wire 3 is coated with epoxy glue. After the wrapping wire 3 is wound around the first armor plate 1, a layer of epoxy glue is coated outside the wrapping wire 3. Therefore, the connection tightness of the covered wire 3 and the second armor plate 2 can be increased, and the driving coil can keep better performance in use.
The winding process needs to ensure a dust-free and positive pressure environment, particularly, metal powder cannot exist in the winding environment, so that the metal powder is prevented from being mixed into a covered wire or a driving coil, and the short circuit of the driving coil is prevented. In addition, when the driving coil is wound, the arrangement of the bare wires is ensured to be smoother through equipment such as a shaping machine, and burrs on the outer portion of the bare wires are reduced. And then the material is wound on a die by using a winding machine to select proper torque force. Meanwhile, the bare wires are required to be tightly arranged in the winding process so as to ensure the working performance of the driving coil.
Further, in step S2, the method further includes:
s21, weaving glass yarns to form a wrapping belt;
and S22, winding the coating tape outside the epoxy glue layer 32 to form the coating layer 33.
The glass fiber has good insulating property and good wettability with epoxy glue. Therefore, the insulating property of the covered wire 3 is ensured by using the covering belt consisting of glass fiber; meanwhile, the adhesiveness between the epoxy glue layer 32 and the coating tape can be increased, and the bare wires 31 and the coating layer 33 are prevented from being layered, so that the heat-conducting property of the driving coil is ensured. In addition, when the cover tape is formed by weaving glass filaments, the formed cover tape has a certain weaving gap. When the covered wire 3 is wound around the first armor plate 1, the epoxy resin is more likely to seep out of the covering tape after being extruded, thereby improving the adhesion of the driving coil.
In step S22, when the wrapping tape is wrapped around the epoxy adhesive layer 32, the width of the adjacent wrapping tape is less than or equal to 1/2 of the width of the wrapping tape, and the wrapping thickness of the wrapping tape is not more than 2 layers.
The width of pressfitting is less than or equal to 1/2 of cladding belt width when the cladding belt is around establishing, can enough guarantee the cladding belt at this moment around the intensity when establishing, is convenient for guarantee simultaneously that the diameter of envelope curve 3 satisfies the operation requirement. Meanwhile, the thickness of the covering layer 33 in the present embodiment is 0.02-0.1mm, so that the size of the driving coil formed by winding the covering wire 3 satisfies the requirements for use thereof. The winding thickness of the wrapping tape is not more than 2 layers, so that the epoxy glue can seep out of the wrapping tape, and the size of the covered wire 3 can meet the use requirement.
When it is necessary to prepare a multi-layered driving coil, it is sufficient by sequentially repeating the operations of step S3 and step S4, and then performing the baking curing in step S5. When a double-layer driving coil is wound, firstly, a covered wire 3 is wound on a first armor plate 1, and then, the other armor plate is coated outside the covered wire 3; and then continuously winding the covered wire 3 outside the armor plate, and covering the second armor plate 2 outside the covered wire 3 after winding. When it is necessary to wind a plurality of layers of the driving coils, the steps S3 and S4 may be repeated in sequence with reference to the above steps.
The first armor plate 1 can be made of aluminum, stainless steel and carbon fiber, and the second armor plate 2 can be made of aluminum, stainless steel and carbon fiber. When the first armor plate 1 and the second armor plate 2 are made of stainless steel or aluminum, the use performance of the driving coil is ensured by limiting the thickness of the first armor plate 1 to be 0.3-0.5mm and the thickness of the second armor plate 2 to be 0.3-0.5 mm. When the thickness of the first armor 1 is less than 0.3mm and the thickness of the second armor 2 is less than 0.3mm, the strength requirements of the first armor 1 and the second armor 2 cannot be guaranteed. When the thickness of the first armor 1 is larger than 0.5mm and the thickness of the second armor 2 is larger than 0.5mm, the mass of the first armor 1 and the mass of the second armor 2 are larger, and the design requirement of lightening the driving coil is not easy to realize.
In order to further reduce the weight of the driving coil, the first shield 1 has a plurality of first communication holes 11, and the second shield 2 has a plurality of second communication holes. The first communicating hole 11 and the second communicating hole are convenient for the infiltration of epoxy glue and first armour 1 and second armour 2 to the fastness when increase covering wire 3 is connected with first armour 1 and second armour 2. Meanwhile, the first communication holes 11 formed in the first armor 1 and the second communication holes formed in the second armor 2 reduce the mass of the first armor 1 and the second armor 2, thereby reducing the mass of the driving coil.
When first armour 1 and second armour 2 chose for use the carbon fiber, because the carbon fiber is combined material, has better insulating nature and epoxy infiltration nature, therefore can guarantee the fastening nature that covered wire 3 and first armour 1 and second armour 2 are connected. Meanwhile, the carbon fiber has the advantages of light weight, good longitudinal mechanical property and the like, so that the quality of the driving coil can be reduced by using the first armor plate 1 and the second armor plate 2 made of the carbon fiber, and the driving coil can be applied to scenes such as wide frequency band and high acceleration.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
