[0002] With the improvement of people's living standards and the advancement of technology, more and more electronic products have entered people's lives and work, bringing convenience to life and work. Many electronic products are inseparable from the cooperation of sound devices such as speakers, so speakers have become an indispensable supporting facility for many electronic products. The speaker shell includes a metal mesh frame and a metal mesh. The speaker shell adopts a metal mesh frame to form a hole for sound transmission, so that the sound of the speaker can be transmitted to the outside. At the same time, in order to reduce the entry of foreign matter such as dust into the interior of the speaker, a metal mesh needs to be set on the inside of the metal mesh frame. Therefore, there is a production step of installing the metal mesh in the metal mesh frame in the production and assembly of the speaker. However, in the prior art, the metal mesh is generally installed manually in the metal mesh frame. The manual alignment and fitting installation has low production efficiency and requires high proficiency of the operator. When the operator's manual operation proficiency is not high, the metal mesh is not accurately installed in the metal mesh frame, which affects the yield of the speaker shell production. Therefore, it is necessary to develop a metal mesh installation device in a metal mesh frame. Utility Model Content
