[0028] A clamping ring 9 is fixed to the top of the connecting ring 7, and three rod holes with equal angles are opened in the clamping ring 9, and a first movable rod 11 is inserted in the rod hole. A clamping plate 15 is fixed to one end of the first movable rod 11, and the clamping plate 15 is located on the inner side of the clamping ring 9. A movable cap 12 is fixed to the other end of the first movable rod 11, and a first spring 10 is fixed between the movable cap 12 and the outer side wall of the clamping ring 9. A horn 16 is arranged inside the clamping ring 9, and the three clamping plates 15 act on the horn 16 synchronously.
[0029] The clamping plate 15 is an arc-shaped structure, and the arc-shaped convex surface of the clamping plate 15 is arranged in the direction of the central axis of the clamping ring 9. When the surface of the speaker is painted, the painting is carried out in the form of a paint roller. In order to make the paint surface of the speaker smoother, the top of the speaker 16 is inserted into the clamping ring 9. With the cooperation of the clamping plate 15, the top port of the speaker 16 is clamped. With the contraction cooperation of the first movable rod 11, the three clamping plates 15 can be contracted to clamp and fix the speaker 16. After clamping, the swing cylinder 6 extends to push the connecting ring 7 to swing, so that the opening of the speaker 16 swings downward;
[0030] After the opening of the horn 16 is adjusted downward, the operation of the lifting cylinder 2, through the cooperation of the connecting plate 3, can realize the lowering of the mounting plate 4. When the mounting plate 4 descends, the clamped horn 16 is sunk, and the mouth of the horn 16 is immersed in the paint, which can realize a more comprehensive painting of the horn 16, and can ensure that the paint surface is more uniform and smoother.
[0031] A warning component 8 is installed on the clamping ring 9, and the warning component 8 includes a support plate 81, and a second movable rod 82 is vertically penetrated in the support plate 81. A limiting cap 88 is fixed to the top of the second movable rod 82, and a second spring 84 is fixed between the limiting cap 88 and the support plate 81. A first electrode sheet 86 is fixed to the top side of the limiting cap 88, and a buoyancy ball 83 is fixed to the bottom end of the second movable rod 82. The warning component 8 also includes a fixing frame 85, and a second electrode sheet 87 is installed on the bottom side of the top cross beam of the fixing frame 85. The first electrode sheet 86 is located directly below the second electrode sheet 87. A signal lamp 14 is installed on the inner wall of one side of the coating box 1, and the signal lamp 14, the first electrode sheet 86, the second electrode sheet 87 and the power supply are connected by wires.

[0032] During operation, after the horn 16 is immersed in the paint, since the paint has a certain buoyancy, as the horn 16 sinks, the buoyancy ball 83 at the bottom of the warning component 8 is affected by the buoyancy of the paint. When the horn 16 sinks, the buoyancy ball 83 can lift the second movable rod 82 to rise, so that the limit cap 88 can rise. After the first electrode sheet 86 contacts the second electrode sheet 87, the triggering operation of the signal light 14 can be realized. The electrical signal of the signal light 14 after being powered on is transmitted to the controller 5, and the controller 5 stops the operation of the lifting cylinder 2, which can ensure that the depth of the horn 16 immersed in the paint liquid level is the same, ensure that the horn 16 is immersed in the same amount of paint, ensure the uniformity of the painting of the horn 16, and ensure the uniformity of the quality of the painting of the horn 16.
[0033] Working principle: In order to make the paint surface of the speaker smoother, the top of the speaker 16 is inserted into the clamping ring 9, and the top port of the speaker 16 is clamped with the cooperation of the clamping plate 15. With the contraction cooperation of the first movable rod 11, the three clamping plates 15 can be contracted to clamp and fix the speaker 16. After clamping, the swing cylinder 6 extends to push the connecting ring 7 to swing, so that the opening of the speaker 16 swings downward;
[0034] After the opening of the speaker 16 is adjusted downward, the lifting cylinder 2 is operated, and the mounting plate 4 can be lowered through the cooperation of the connecting plate 3. When the mounting plate 4 is lowered, the clamped speaker 16 is sunk, and the mouth of the speaker 16 is immersed in the paint, so that the speaker 16 can be painted more comprehensively, and the paint surface can be more uniform and smoother.
[0035] After the horn 16 is immersed in the paint, since the paint has a certain buoyancy, as the horn 16 sinks, the buoyancy ball 83 at the bottom of the warning component 8 is affected by the buoyancy of the paint. When the horn 16 sinks, the buoyancy ball 83 can lift the second movable rod 82 to rise, so that the limit cap 88 can rise. After the first electrode sheet 86 contacts the second electrode sheet 87, the signal light 14 can be triggered. After the signal light 14 is powered on, the electrical signal is transmitted to the controller 5, and the controller 5 stops the operation of the lifting cylinder 2, which can ensure that the depth of the horn 16 immersed in the paint liquid level is the same, ensure that the horn 16 is immersed in the same amount of paint, ensure the uniformity of the painting of the horn 16, and ensure the uniformity of the quality of the painting of the horn 16.
