[0001] The utility model belongs to the technical field of loudspeaker production, in particular to an automatic sound film machine for loudspeaker production. Background Art

[0002] A speaker is an electroacoustic transducer, specifically an instrument that can amplify sound. It is also called a "horn" and is a common device.

[0003] In the production of existing speakers, an automatic film coating machine is required to coat the sound-generating unit of the speaker. Coating the sound-generating unit can protect the sound-generating unit and increase the performance of the speaker. When coating the speaker, the speaker needs to be coated with glue.

[0004] It has been found in long-term use and observation that the existing automatic sound film machine needs to be coated with glue when processing the sound unit. When the glue is coated, the glue is fluid, so the glue may flow out from the end of the sound unit, causing waste.

Through the above structure, on the one hand, the applied glue can be smoothed, and on the other hand, the glue can be preliminarily dried, thereby making the glue coating surface wider, and preliminarily drying and shaping the glue can reduce the occurrence of glue flowing out of the outside.

[0008] Preferably, two slide grooves are provided on the top of the slider; the two slide grooves are symmetrically arranged; a spring is fixedly connected to the side wall of the slide groove; an arc plate is fixedly connected to the end of the spring; the arc plate and the slide groove are in sliding cooperation. Through the above structure, the speaker components can be fixed, thereby reducing the position deviation of the speaker components when the speaker components are glued, thereby reducing the occurrence of offset of the gluing position.

[0009] Preferably, a fixing ring is fixed to the bottom of the protective shell; a plurality of brushes are fixed to the bottom of the fixing ring; the plurality of brushes are evenly distributed and flexibly arranged. Through the above structure, the speaker components can be cleaned, thereby reducing the absorption of dust or impurities on the surface of the speaker components, thereby reducing the occurrence of situations affecting the gluing.

At this time, the sliding assembly 1 is started, and the slider 13 is driven to move on the top of the sliding assembly 1 as the sliding assembly 1 is started. Slide, at this time, the speaker parts will move synchronously with the movement of the slider 13, and by starting the glue coating device 12, when the speaker parts move to the bottom of the injection cylinder 15, as the glue coating device 12 is started, the glue coating device 12 will drive the storage cylinder 14 to move, thereby driving the injection cylinder 15 to move, and when the injection cylinder 15 contacts the speaker parts, the speaker parts can be glued. At this time, as the injection cylinder 15 is glued on the movement of the speaker parts, the support rod 19 in the middle of the injection cylinder 15 will move with the movement of the injection cylinder 15, and at the same time drive the smear plate 110 to move synchronously, and the glue The glue flowing out from the end of the injection cylinder 15 will be simultaneously smoothed by the screed plate 110, and the heating wire 17 will be started synchronously at this time.

[0024] like Figure 2As shown, two slide grooves 2 are provided at the top of the slider 13; the two slide grooves 2 are symmetrically arranged; a spring 21 is fixedly connected to the side wall of the slide groove 2; an arc plate 22 is fixedly connected to the end of the spring 21; the arc plate 22 is in sliding cooperation with the slide groove 2. During operation, when the speaker components are transported, the speaker components are placed in the middle of the two slide grooves 2. At this time, as the speaker components squeeze the arc plate 22, the arc plate 22 will slide inside the slide groove 2. When the arc plate 22 slides, the spring 21 will retract. At this time, when the bottom of the speaker component contacts the top of the slider 13, the spring 21 rebounds, thereby driving the arc plate 22 to slide again. At this time, the speaker component can be fixed. Through the above structure, the speaker components can be fixed, thereby reducing the position deviation of the speaker components when the speaker components are glued, thereby reducing the occurrence of the offset of the glue coating position.

[0025] like Figure 3 and Figure 4 As shown, a fixing ring 3 is fixedly connected to the bottom of the protective shell 16; a plurality of brushes 31 are fixedly connected to the bottom of the fixing ring 3; the plurality of brushes 31 are equidistantly distributed and flexibly arranged. When working, as the sliding component 1 is started, the slider 13 will be driven to slide on the top of the sliding component 1. At this time, the speaker parts will slide with the sliding of the slider 13. At this time, as the speaker parts slide, the speaker parts will contact the brush 31. At this time, the brush 31 will clean the speaker parts. Through the above structure, the speaker parts can be cleaned, thereby reducing the absorption of dust or impurities on the surface of the speaker parts, thereby reducing the occurrence of the situation that affects the gluing.

[0026] like Figure 2 As shown, the side wall of the arc plate 22 is fixedly connected with an elastic band 4; the other end of the elastic band 4 is fixedly connected to the top of the slider 13. During operation, as the speaker components squeeze the arc plate 22, the arc plate 22 will slide inside the slide groove 2. At this time, as the arc plate 22 slides, the arc plate 22 will drive the elastic band 4 to stretch. At this time, the elastic band 4 can block the top of the slide groove 2. Through the above structure, the elastic band 4 can block the slide groove 2, thereby reducing dust or impurities from entering the interior of the slide groove 2, resulting in dust or impurities accumulating inside the slide groove 2, which makes it difficult for the arc plate 22 to slide inside the slide groove 2.

[0030] During operation, glue is filled in the storage tube 14, and then the speaker parts that need to be glued are placed on the top of the slider 13. At this time, the sliding component 1 is started. As the sliding component 1 is started, the slider 13 is driven to slide on the top of the sliding component 1. At this time, the speaker parts will move synchronously with the movement of the slider 13. At this time, by starting the glue coating device 12, when the speaker parts move to the bottom of the injection cylinder 15, as the glue coating device 12 is started, the glue coating device 12 will drive the storage tube 14 to move, thereby driving the injection cylinder 15 to move.

With the start of the heating wire 17, the temperature inside the protective shell 16 will increase, and the glue can be preliminarily dried. At this time, the support rod 19 is opened to make the inside of the protective shell 16 ventilated so that the temperature inside the protective shell 16 will not be too high. When transporting the speaker parts, the speaker parts are placed in the middle of the two slide grooves 2. As the speaker components squeeze the arc plate 22, the arc plate 22 will slide inside the slide groove 2. When the arc plate 22 slides, the spring 21 will retract. At this time, when the bottom of the speaker component contacts the top of the slider 13, the spring 21 rebounds, thereby driving the arc plate 22 to slide again. At this time, the speaker components can be fixed. As the sliding assembly 1 is started, the slider 13 will slide on the top of the sliding assembly 1. At this time, the speaker components will slide with the sliding of the slider 13. At this time, as the speaker components slide, the speaker components will contact the brush 31. At this time, the brush 31 will clean the speaker components. As the speaker components squeeze the arc plate 22, the arc plate 22 will slide inside the slide groove 2. At this time, as the arc plate 22 slides, the arc plate 22 will drive the elastic band 4 to stretch. At this time, the elastic band 4 can block the top of the slide groove 2. By opening the heat dissipation holes 18, a ventilated environment can be formed inside the protective shell 16. At this time, by installing the dustproof net 5, dust or impurities can be reduced from entering the inside of the protective shell 16 through the heat dissipation holes 18. As the speaker components are placed in the middle of the two arc plates 22, the speaker components can be fixed. At this time, by setting the cushion layer 6, the cushion layer 6 with a softer material can directly contact the side wall of the speaker components.
