A suction pipe 474 is disposed on a side of the mounting plate 471 away from the fixing member 46, one end of the suction pipe 474 is connected to the mounting plate 471, the other end extends toward a direction away from the mounting plate 471, the mounting plate 471 is provided with a suction hole 472, the suction hole 472 sequentially penetrates the mounting plate 471 and the suction pipe 474, the suction hole 472 is communicated with the cavity 48, wherein the mounting plate 471 may be provided with a plurality of suction holes 472; or, the end of the suction pipe 474 far away from the mounting plate 471 is provided with a plurality of suction holes 472, and the suction holes 472 sequentially penetrate through the suction pipe 474 and the mounting plate 471 and are communicated with the first groove 475 through the avoiding space formed at the necking connection section 476. Therefore, by setting the suction pipe 474 with a proper length, on one hand, the moving distance of the suction arm 44 can be reduced, and the material taking efficiency is improved, and on the other hand, taking the annular sheet 61 and the limiting member 53 penetrating through the central hole 62 thereof as examples, the pipe cavity of the suction pipe 474 can avoid the limiting member 53, and meanwhile, the suction hole 472 arranged at the end part of the suction pipe 474 can directly contact with the outer surface of the annular sheet 61 to perform the material taking by adsorption. Preferably, the suction holes 472 are arranged in a circumferential array manner with the center line of the suction pipe 474 as the center, which is beneficial to ensuring the uniformity of suction force distribution and improving the firmness of material taking.

In the present utility model, for the magnetron production apparatus, the sheet material feeding device described in the present embodiment may be included, and on the basis of the related structure and the assembly relationship of the sheet material feeding device provided in the present embodiment, the magnetron production apparatus further includes an exhaust pipe assembly device, a cathode assembly device, an anode assembly device, and the like, and accordingly, reference may be made to the applicant's early patents, other units, or related prior arts of individuals, which are not described herein.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
