Description

Technical Field

[0001] This utility model relates to the field of loudspeaker processing technology, specifically to a dispensing device for loudspeaker processing. Background Technology

[0002] The headphone speaker, also known as a driver, is the core component of headphone sound production. The working principle of a headphone speaker is similar to that of an electrodynamic speaker, both based on the principle of electromagnetic induction. When an electric current passes through the voice coil in the headphone speaker, the voice coil experiences a force in a permanent magnetic field, causing it to vibrate. These vibrations drive the diaphragm (or cone, etc.) connected to the voice coil, thus transmitting sound waves into the air and producing sound. In the manufacturing process of this type of speaker, a dispensing device is needed to apply adhesive to the speaker for precise bonding and reinforcement of the internal components, completing the connection between the headphone shell or other components and the speaker. Existing dispensing devices for speaker manufacturing suffer from problems such as adhesive solidification inside the dispensing head, causing blockage, and difficulty in precisely controlling the amount of adhesive dispensed each time, resulting in either too much or too little adhesive and poor dispensing quality. Therefore, this application proposes a dispensing device for speaker manufacturing to solve these problems. Utility Model Content

[0011] Preferably, the top end of the storage cylinder and the bottom end of the lower glue cylinder are connected by a thread, and the dispensing head is connected to the storage cylinder by a thread.

[0012] (III) Beneficial Effects

[0013] The beneficial effects of this utility model are as follows:

[0014] This type of dispensing device for loudspeaker processing prevents the adhesive from solidifying in the cylinder through the cooperation of a heating rod and a stirring rod, ensuring that the adhesive in the cylinder can flow to the storage cylinder. The amount of adhesive flowing from the cylinder to the storage cylinder can be controlled by the rotation of the rotating plate. Then, the storage cylinder is pressurized by an air pump and an air filling pipe, and the adhesive in the storage cylinder is squeezed out of the dispensing head through the dispensing hole to the loudspeaker. By changing different models of dispensing heads, different numbers of dispensing holes can be used to dispense adhesive to the loudspeaker, meeting the dispensing needs of different areas of the loudspeaker.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a dispensing device for speaker processing, including a cylindrical body 1, a mounting bracket 2 connected to the top side of the cylindrical body 1, a control panel installed on the front side of the mounting bracket 2 for controlling the dispensing device for speaker processing, the mounting bracket 2 for mounting the cylindrical body 1 on the headphone speaker processing production line, so that the dispensing head 12 at its bottom corresponds to the headphone speaker processing production line, a lower glue cylinder 3 connected to the bottom end of the cylindrical body 1, two glue dispensing holes 4 longitudinally opened on the top side wall of the lower glue cylinder 3, a rotating plate 5 provided inside the lower glue cylinder 3, the rotating plate 5 tightly attached to the top side inner wall of the lower glue cylinder 3, two docking holes 6 transversely opened on the rotating plate 5, the rotating plate 5 connected to a shaft 7. The shaft 7 passes through the lower glue cylinder 3 and the cylinder 1, connecting to the drive motor 8. Multiple stirring rods 9 are mounted on the shaft 7. A heating rod 10 is also installed inside the cylinder 1. A temperature control module is located at the top of the heating rod 10 on the top side of the cylinder 1. The glue-adding pipe on the top side of the cylinder 1 delivers the glue into the cylinder 1. When the heating rod 10 is activated, it heats the glue inside the cylinder 1. Driven by the drive motor 8, the shaft 7 rotates. As the shaft 7 rotates, the stirring rods 9 also mix the glue inside the cylinder 1. The shaft 7 also drives the rotating plate 5 to rotate intermittently, achieving intermittent docking of the docking hole 6 and the lower glue hole 4. When the docking hole 6 and the lower glue hole 4 dock, the glue inside the cylinder 1 flows into the storage tank. The bottom of the lower glue cylinder 3 is connected to the storage cylinder 11, and the bottom of the storage cylinder 11 is connected to the dispensing head 12, which has a dispensing hole 13. The storage cylinder 11 is connected to the inflation tube 14, which is connected to the air pump 15, which is installed on the outer wall of the cylinder body 1. When the docking hole 6 and the lower glue hole 4 are misaligned, the storage cylinder 11 is sealed except for the dispensing hole 13 at the bottom. The air pump 15 inflates the storage cylinder 11 and delivers the air through the inflation tube 14 to the upper side of the storage cylinder 11, so that the glue in the storage cylinder 11 is squeezed out through the dispensing hole 13 onto the speaker. The dispensing head 12 is provided with multiple different models, and the number of dispensing holes 13 on the different models of dispensing head 12 is different. This device is used for dispensing adhesive to different areas of a loudspeaker, meeting the dispensing needs of different areas of the loudspeaker. Multiple storage cylinders 11 are available in different models, each with a different storage capacity, allowing for adjustment of the amount of adhesive dispensed each time. The top of the storage cylinder 11 is connected to the bottom of the lower adhesive cylinder 3 via a threaded connection. The spiral pattern on the inner wall of the top of the storage cylinder 11 and the outer wall of the bottom of the lower adhesive cylinder 3 is used for the threaded connection. The dispensing head 12 is also connected to the storage cylinder 11 via a threaded connection. The spiral pattern on the outer wall of the dispensing head 12 and the inner wall of the bottom of the storage cylinder 11 is used for the threaded connection, making it easier to replace and adjust the storage cylinder 11 and the dispensing head 12.

[0022] like Figure 4As shown, the dispensing head 12 can also be configured to dispense glue via a needle 16 instead of the dispensing hole 13, for use with different dispensing methods for headphone speakers.

[0023] The operational steps for this application are as follows:

[0024] The colloid delivery pipe on the top side of the cylinder 1 delivers colloid into the cylinder 1. After the heating rod 10 is started, it heats the colloid in the cylinder 1. Driven by the drive motor 8, the shaft 7 rotates. When the shaft 7 rotates, the stirring rod 9 also mixes and stirs the colloid in the cylinder 1. The shaft 7 also drives the rotating plate 5 to rotate at intervals, realizing the interlocking of the docking hole 6 and the dispensing hole 4. When the docking hole 6 and the dispensing hole 4 are connected, the colloid in the cylinder 1 flows into the storage cylinder 11. When the docking hole 6 and the dispensing hole 4 are misaligned, the storage cylinder 11 is sealed except for the dispensing hole 13 at the bottom. The air pump 15 inflates and delivers air to the upper side of the storage cylinder 11 through the air inflator 14, so that the colloid in the storage cylinder 11 is squeezed out onto the speaker through the dispensing hole 13.
