In some embodiments, changing coating 22 is multi-turn, when to changing the progress electroplating processes of coating 22, enclosing and being arranged every 2-5
One conductive electrode 3, conductive electrode 3 is arranged in this way can keep the uniformity of electroplated layer, and multiple conductive electrodes 3 are arranged can
The uniformity of electric field strength when guaranteeing plating, to guarantee the uniformity of plating thickness.
When further, to the progress electroplating processes of coating 22 are changed, the coil panel 100 with conductive electrode 3 is immersed into plating
It in liquid, and is powered to conductive electrode 3, carries out electroplating processes.Because only that conductive electrode 3 is arranged in the change coating 22 of coil 2, i.e., only
22 energized conductor of having coating, therefore when electroplating processes, electroplated layer only is formed on changing coating 22, thickens the thickness of coil 2.
In some embodiments, it is formed as follows as shown in figure 8, changing coating:
Chemical plating is carried out to active layer and forms metal layer 21, since the activity of active layer is high, the metal layer that chemical plating is formed
21 is more evenly and more efficient；
The a part for removing metal layer 21 forms the change coating 22 of coil 2, and a part being removed in metal layer 21 is formed
Gap between adjacent windings 2.Specifically, needing to remove one of metal layer 21 to form the change coating 22 of coil 2
Point, to form an at least circleization coating 22, it is to be understood that part when change coating 22 is multi-turn, between two adjacent rings
Metal layer 21 is removed, and forms the gap between two adjacent rings coating 22.
It is formed that is, changing coating 22 by removing a part of metal layer 21, metal layer 21 is adhered to by chemical plating
On active layer, electroplated layer passes through on plating being attached to coating 22.Optionally, metal layer 21 can be layers of copper or nickel layer.
Optionally, metal layer 21 can be matched with the rough surface shape of coil bracket 1.Such as in some embodiments
In, the entire outer surface 11 of coil bracket 1 forms rough surface, and 21 full wafer of metal layer is covered on the appearance of coil bracket 1
On face 11.In specifically embodiment as shown in Figure 3, coil bracket 1 is peviform, and metal layer 21 is also peviform.Certainly another
In some embodiments, the outer surface 11 of the bottom of coil bracket 1 forms rough surface, and metal layer 21 covers coil bracket 1
Bottom outer surface 11.
Optionally, metal layer 21 removes a part of formationization coating 22 of metal layer 21 by laser scanning cutting, thus
Simple process, accurate to dimension are high, high-efficient, and the deformation for changing coating 22 is small or does not deform, ensure that coating 22
Dimensional accuracy.It is understood that the thickness of metal layer 21, that is, change the thickness of coating 22.
Coil disc manufacturing method according to an embodiment of the present invention, it is multiple by being formed in the outer surface of coil bracket 1 11
Pit 12, to make coil 2 and coil bracket 1 mutually penetrate into chemical plating and plating, improve coil 2 and coil panel branch
The binding force of frame 1, and the material requirements of coil bracket 1 is greatly reduced, coil bracket 1 resistant to high temperature can be selected, it is full
The heatproof requirement of sufficient coil panel 100, when preventing high-temperature heating, 2 delamination of coil.
The coil panel 100 produced using coil disc manufacturing method of the invention and traditional is briefly described below
The coil panel that LDS method produces carries out the test result comparison of 1250W temperature rise test to boil water, and test result is compared such as following table institute
Show, wherein the distribution of test point is as shown in T1, T2, T3, T4, T5, T6, T7 in Fig. 6.
