[0002] A loudspeaker, also known as a "speaker", is a transducer that converts an electrical signal into a sound signal. The performance of a loudspeaker has a great impact on the sound quality. Audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects and resonate (sympathize) with the surrounding air to emit sound. With the rapid development of electronic information technology, more and more loudspeakers are used on various electronic products. As the core component of a loudspeaker, the quality of the diaphragm design directly affects the performance of the loudspeaker.

[0003] At present, the diaphragm is mainly manufactured by hot pressing. For example, the patent with the publication number CN209920514U, named a diaphragm hot pressing forming machine, includes a frame and a top plate installed on the frame; a film cavity is provided on the lower side of the top plate, and an air pipe is connected to the film cavity; an upper heating plate is installed on the frame, and a bottom heating mechanism is provided on the lower side of the upper heating plate; the bottom heating mechanism includes a lower heating plate and a cylinder for driving the lower heating plate to move up and down, and the output end of the cylinder is connected to the lower heating plate; the diaphragm hot pressing forming machine further includes a pushing mechanism for driving the film cavity to move up and down and a heating mechanism capable of realizing regional temperature control.

[0004] However, in the process of using the existing hot pressing forming device, after the diaphragm is hot pressed, it needs to be manually blanked, and the efficiency is low.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Please refer to Figures 1-3 , an embodiment provided by the present utility model: an air blowing blanking device for earphone diaphragm forming, including a workbench 1;

[0026] It further includes:

[0027] A positioning block 2, which is installed at the rear end above the workbench 1;

[0028] A cutting table 3, which is installed at the front end above the workbench 1, and a blanking mechanism 4 is installed above the cutting table 3;

[0029] A first pneumatic push rod 6, which is installed below the front end of the cutting table 3. The output end of the first pneumatic push rod 6 penetrates and extends to the inside of the cutting table 3, and a first sliding table 7 is installed. A guide rail seat 9 is installed above the first sliding table 7. A second pneumatic push rod 10 is installed at the rear end of the guide rail seat 9. The output end of the second pneumatic push rod 10 penetrates and extends to the inside of the guide rail seat 9, and a second sliding table 11 is installed. Pneumatic grippers 12 are installed on both sides above the second sliding table 11;

[0030] A first blowing seat 14, which is installed on one side of the workbench 1. A second blowing seat 15 is inclinedly arranged inside the front end of the guide rail seat 9. A plurality of blowing holes 16 are arranged on the outer walls of the first blowing seat 14 and the second blowing seat 15.

[0031] Please refer to Figure 1, on both sides of the first slide table 7, first guide posts 8 are installed inside. Both ends of the first guide posts 8 penetrate and extend into the inside of the cutting table 3 and the positioning block 2 respectively. On both sides of the second slide table 11, second guide posts 13 are installed inside. Both ends of the second guide posts 13 are fixedly connected to the inner walls at both ends of the guide rail base 9. The setting of the guide post structure can play an auxiliary guiding role during the movement of the slide table along with the pneumatic push rod, so as to improve the movement accuracy.

[0032] Please refer to Figure 1 and Figure 3 , the blanking mechanism 4 includes a carrier table 401, a bracket 402, a hydraulic cylinder 403 and a tool holder 404. The four corners at the lower end of the carrier table 401 are connected to the cutting table 3 through the bracket 402. The hydraulic cylinder 403 is installed above the carrier table 401. The output end of the hydraulic cylinder 403 penetrates and extends below the carrier table 401, and a tool holder 404 is installed. A blade 405 is installed on the lower surface of the tool holder 404. Since one end of the film material is wound around the winding roller during hot pressing, after hot pressing, the blanking mechanism 4 can cut off the formed part of the film material to facilitate blanking.

[0033] Please refer to Figure 1 , a cutting avoidance groove 5 is arranged on the upper surface of the cutting table 3. The setting of the cutting avoidance groove 5 can prevent the cutting table 3 from being damaged when the blanking mechanism 4 punches.

[0034] Please refer to Figure 1 , a material receiving box 17 is arranged on one side of the workbench 1. The hot-pressed sound film material can be blown into the material receiving box 17 under the action of the ejection angle formed by the first ejection seat 14 and the second ejection seat 15 to complete the automatic blanking work.

[0035] Working principle: When in use, the device is arranged on one side of the hot pressing and forming machine. After the sound film is hot pressed, the first pneumatic push rod 6 controls the contraction of the output end, so that the first slide table 7 moves towards the hot pressing and forming machine, driving the pneumatic gripper 12 on the second slide table 11 to approach the sound film material, using the pneumatic gripper 12 to grip one side of the sound film material. After that, the first pneumatic push rod 6 extends again, pulling the sound film material out for a certain distance, and cooperating with the punching of the blanking mechanism 4 to separate the sound film material from the film material wound around the winding roller. Then the second pneumatic push rod 10 extends, further driving the sound film material to move between the angles of the first ejection seat 14 and the second ejection seat 15. The first ejection seat 14 and the second ejection seat 15 are connected to an air pump through an air pipe. While the pneumatic gripper 12 releases the material, the blowing action of the first ejection seat 14 and the second ejection seat 15 controls the material to fall into the material receiving box 17 to realize automatic blanking.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights.
