The first fixing plate 400 may be disposed on a side close to the base 100, and the second fixing plate 500 is disposed on a side away from the base 100, or the first fixing plate 400 is disposed on a side away from the base 100, and the second fixing plate 500 is disposed on a side close to the base 100, which may be disposed according to actual requirements.
Specifically, the position of the pull rod 600 on the second fixing plate 500 can be adjusted along the axial direction relative to the second fixing plate 500 by setting the pull rod 600 on the first fixing plate 400, the position of the pull rod 600 on the first fixing plate 400 and the position of the pull rod 600 on the second fixing plate 500 can be adjusted along the axial direction relative to the second fixing plate 500 when the same heating cage has different temperature distribution area requirements, thereby achieving the purpose that the heating wires 801 with different densities are wound on one cage-shaped heating wire winding device to meet the requirement that the same heating cage has different temperature distribution areas, and also winding different shapes of heating cages, which is simple and convenient to operate, and the heating wires 801 wound on one cage-shaped heating wire winding device are continuous, the heating cages wound out by the same have higher consistency, and in the existing mode, the first heating wires 10 with different winding densities can be manufactured by adopting winding wire tools with different specifications generally, and then the first heating cages with different winding densities are assembled into one heating cage to meet the different temperature distribution area requirements, which cannot be manufactured by using one winding tool with different winding densities, and the heating cages can be manufactured by using different winding wire distribution areas, and the heating cages can be manufactured by using different heating wires, and the heating wires, which the heating cages can be assembled into a heating cage with different winding wires, and the heating cages can be conveniently and the heating cages.
In practical applications, the heating cage is mainly a device for electrifying a heating wire 801 to generate thermal radiation so as to make the material in the heating cage reach a certain temperature, thereby evaporating the material to form a molecular beam flow under a high vacuum state, the material of the heating wire 801 is generally a high-purity tantalum wire or tungsten wire with a certain diameter, the heating wire 801 has certain strength and plasticity, the existing heating wire (for distinction, the heating wire in the prior art is hereinafter referred to as a first heating wire 10) needs to be wound on a support ring (for distinction, the support ring in the prior art is hereinafter referred to as a first support ring 20) in a certain layout manner, as shown in fig. 8, fig. 8 is a schematic structural diagram of the heating cage in the prior art, the heating cage comprises the first heating wire 10 and a plurality of first support rings 20, the first heating wire 10 is wound on the plurality of first support rings 20 in a circuitous manner, and the first heating wires 10 are bent and returned to form bent portions at the outermost first supporting rings 20, in order to make the uniformity of the temperature field of the heating cage good when the first heating wires 10 are wound, in addition to ensuring the uniform radius of the bent portions, it is also required to ensure that the portions of the first heating wires 10 between the first supporting rings 20 are kept straight, because the first heating wires 10 are distributed more densely, and the distance between two adjacent first heating wires is about 3mm, therefore, slight bending between the first heating wires 10 (except the bent portions) also has a great influence on the uniformity of the overall temperature of the heating cage, the winding method of the first heating wires 10 in the prior art is as shown in fig. 9 (fig. 9 is a schematic diagram for more clearly expressing and does not represent a specific object diagram), in fig. 9, the first heating wires 10 pass through b1 holes of the first supporting rings 20 (indicated by a rectangle in fig. 9), then are bent and pass through adjacent b2 holes, then, the first heating wire 10 is stretched below the hole b2, so that the radius of the bent part at the position from b1 to b2 meets the requirement, in the process, a section from the hole b1 to the hole b2 in the first heating wire 10 in the state A1 can be bent (i.e. a section A1), because the distance between the hole b1 and the hole b2 is relatively small, the curvature of the bent part is relatively large, and the bent first heating wire 10 can generate plastic deformation, even if the first heating wire is stretched in the state A2 (during stretching, the section A1 can be stretched to the section A2), the first heating wire is finally stretched to the section A3 in the state A3, the section A3 can be bent finally and is difficult to be corrected again, so that the temperature distribution uniformity of the heating cage is affected, and by adopting the cage-shaped heating wire winding device of the present application, the heating wire 801 only bends a part of the heating wire at the position where the heating wire 801 needs to be bent, and the heating wire 801 of the rest does not need to be bent through a large-curvature bending process, so that the probability of the heating cage for generating plastic deformation can be greatly reduced, and the field distribution probability of the heating cage 801 is effectively ensured.
In addition, the irregular arc lines at the bending part of the heating cage also affect the uniformity of the temperature field, as shown in fig. 10, the distance between two holes (as d in fig. 10) on the first supporting ring 20 is relatively small, the operating space is small, the first heating wire 10 in the prior art experiences the arc line in the C1 state as shown in fig. 10 when being bent, and then bends and stretches to finally form the arc line in the C2 state, because the first heating wire 10 has certain toughness, the first heating wire 10 can not continuously shrink any more, and only the irregular arc line in the C2 state can be formed by the first heating wire 10, so that the temperature field of the whole heating cage is not uniform; by the aid of the cage-shaped heating wire winding device, only the bending part of the heating wire 801 needs to be directly bent on the barb part 700, and the heating wire 801 forms a regular bending part on the barb part 700 through certain pulling force before and after bending, so that arcs with regular shapes in a C3 state in fig. 10 can be obtained, and uniformity of a temperature field of the heating cage is guaranteed.
