Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A glue dripping device for the outer ring of a dual-channel internal magnetic speaker assembly machine, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a glue dropping bin 1, a glue tank 2, a placement tray 3, a glue dropping tube 4 and a rotating component 5. The upper middle side of the glue dropping bin 1 is connected to a glue tank 2 for storing output glue, and the lower middle part of the glue dropping bin 1 is connected to a placement tray 3 for placing a speaker. The lower middle side of the glue tank 2 passes through the middle of the upper part of the glue dropping bin 1 and is rotatably connected to a glue dropping tube 4 for dripping glue on the outer ring of the speaker. The lower part of the glue dropping tube 4 is connected to a conical nozzle, and the glue dripping pressure is greater. The middle right side of the upper part of the glue dropping bin 1 is connected to a rotating component 5 for driving the glue dropping tube 4 to rotate and drip glue. The rotating component 5 includes a mounting frame, a driving motor, a pulley and a transmission belt. The middle right side of the upper part of the glue dropping bin 1 is connected to a mounting frame, and the driving motor is connected to the mounting frame.

[0021] This device can be used when dripping glue on the outer ring of the speaker. It should be noted that first, a sufficient amount of glue is injected into the glue tank 2, and then the lifting component 65 is started, so that the left and right parts of the lifting component 65 slide upward. At this time, the flip rod 63 is separated from the downward pressure state of the lifting component 65, and then the flip rod 63 drives the adjacent insulation plate 61 to rotate downward and fit between the glue tank 2. At the same time, the connecting rod 62 drives the lower insulation plate 61 to fit between the glue tank 2.

At the same time, the speaker that needs to be dripped with glue is placed on the placement plate 3, and then the glue tank 2 is used to drip glue on the outer ring of the speaker through the glue dripping tube 4. , and at the same time, the rotating component 5 is started, so that the upper part of the rotating component 5 rotates to drive the glue dripping tube 4 to rotate, and then the glue dripping tube 4 rotates to drip glue on the outer ring of the speaker. After the glue dripping is completed, the glue tank 2 is used to stop discharging, and the rotating component 5 and the insulation plate 61 are closed at the same time, so that the speaker on the placement plate 3 can be taken out, and then the lifting component 65 is closed, so that the left and right parts of the lifting component 65 press down the adjacent flip rods 63, and then the flip rods 63 drive the insulation plate 61 to separate from the glue tank 2. In summary, through the cooperation between the lifting component 65 and the flip rod 63, the insulation plate 61 is driven to heat and keep the surface of the glue tank 2 warm, so as to avoid the glue in the glue tank 2 from cooling and condensing, thereby maintaining the smoothness of the glue output.
