Specifically, the first positioning ring 2 is mounted on the substrate 1 through an adjusting stud 21, two adjusting nuts 22 are connected to the adjusting stud 21 through threads, the adjusting stud 21 is arranged in the corresponding third strip-shaped hole 13 in a penetrating manner, the two adjusting nuts 22 are respectively abutted to two main surfaces of the substrate 1 along the Z-axis direction, and the substrate 1 is extruded between the two adjusting nuts 22; when the installation position of the first positioning ring 2 needs to be adjusted, firstly, the adjusting nut 22 is unscrewed, then, the adjusting nut 22 moves along the third strip-shaped hole 13 until the adjusting nut 22 is locked after the adjusting nut moves to the target position, and the position adjustment of the first positioning ring 2 is realized; in this embodiment, the structure of the second positioning ring 4 and the matching relationship between the second positioning ring 4 and the substrate 1 are the same as those of the first positioning ring 2, and are not described herein again.
Alternatively, the number of idler assemblies need not be four, but could be two, three, five, etc. Optionally, the plurality of guide wheel assemblies may further include a fixed wheel assembly 7, the adjusting wheel assembly 5 is located at one end of each guide wheel assembly in the forward direction of the X axis, and the number and the positional relationship of the fixed wheel assembly 7 and the adjusting wheel assembly 5 may be specifically set according to the adjustment requirement, for example, as shown in fig. 4, the number of the guide wheel assemblies is still four, and the four guide wheel assemblies are respectively a first fixed wheel assembly 7a, an adjusting wheel assembly 5, a second fixed wheel assembly 7b and a positioning wheel assembly 6 which are sequentially distributed in the forward direction of the X axis.
The specific structure of the fixed wheel assembly 7 can be set by referring to the adjusting wheel assembly 5 or the positioning wheel assembly 6, and is not described in detail here.
Optionally, also can adopt the roller train (not shown in the figure) to replace the first locating ring 2 of this embodiment, and first locating ring 2 and roller train are first location structure, and the roller train includes the gyro wheel of two borders on, and bare copper wire 8 extrudes between two gyro wheels, and the position of bordering on of two gyro wheels is static relatively when the roller train rotates, can realize the location to bare copper wire 8 like this to be difficult to cause the damage to bare copper wire 8 more. However, the roller group is more complicated than the first positioning ring 2 in structure, and because the tension of the bare copper wire 8 is smaller when the tension adjusting device of the embodiment is just introduced, the bare copper wire 8 is guided and positioned by the first positioning ring 2 and the second positioning ring 4 without causing large friction damage to the bare copper wire 8, and therefore, the first positioning ring 2 is preferred in the embodiment to provide positioning guidance for the bare copper wire 8 to introduce the tension adjusting device, and similarly, the second positioning ring 4 is preferred in the embodiment to provide positioning guidance for the bare copper wire 8 to introduce the tension adjusting device.
Alternatively, the positioning wheel assembly 6 can be replaced by a positioning ring similar to the first positioning ring 2 and the second positioning ring 4, and the positioning function can be realized as well, so as to realize the position corresponding to the annealing device. However, the bare copper wire 8 already has a certain tension when leading out the tension adjusting device, and at this time, if the positioning ring is used to position the routing position of the bare copper wire 8, the bare copper wire 8 may be worn greatly, and therefore, the positioning wheel assembly 6 is adopted in this embodiment to provide positioning guidance for the bare copper wire 8 leading out the tension adjusting device.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
