Description

Technical Field

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

[0002] During the assembly of the earphone shell using adhesive dispensing, an adhesive dispensing machine is required. To accelerate the drying speed of the adhesive, the assembled shell needs to be heated. During the dispensing process, the adhesive dispensing machine not only needs to fix the shell in place but also needs to handle the adhesive vapors that evaporate during heating.

[0003] The prior art includes a dispensing device for manufacturing and processing headphone sockets, disclosed in CN221245868U. This device comprises a support base, a clamping assembly, and a drying mechanism. Multiple sets of support blocks are fixedly installed on the top of the support base, and an mounting block is positioned above the support base. The clamping assembly, located on top of the support base, includes a threaded rod, internally threaded blocks, assembly clamps, and a connecting rod. The outer wall of the threaded rod is threadedly connected to the internal threads of the multiple sets of internally threaded blocks. The top of the internally threaded blocks is fixedly connected to one end of the connecting rod, and an assembly clamp is fixedly installed at the other end of the connecting rod. Another set of assembly clamps is fixedly installed on the top of the support blocks. The drying mechanism, located above the support base, includes an air-gathering chamber and an air-discharge pipe. The mounting block has an air-gathering chamber inside, and its bottom is fixedly connected to and communicates with one end of the air-discharge pipe. An air-discharge nozzle is fixedly installed at the other end of the air-discharge pipe.

[0004] When the above-mentioned equipment is in use, harmful gases will be released during the heating and drying process of the earphone holder, which will affect the health of the staff. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the aforementioned problems in the prior art, this utility model provides a dispensing device for assembling headphones, which facilitates the placement and removal of the headphone shell, can fix the headphone shell, and can also collect volatile harmful gases.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] A dispensing device for assembling headphones includes a support frame, a lifting dispensing mechanism, and a drying mechanism. The support frame has a placement seat that cooperates with the lifting dispensing mechanism. The placement seat has a placement groove, an air channel inside, and a longitudinal vent hole communicating with the air channel at its bottom. A suction pump and a waste gas pipe connected to the air channel are located on one side of the back of the placement seat. The depth of the placement groove is less than the thickness of the headphone shell. This device facilitates the placement and removal of the headphone shell, secures the headphone shell, and collects any volatile harmful gases.

[0010] Preferably, the lifting dispensing mechanism includes a hydraulic cylinder assembly, a lifting block, a connecting rod, a fixing frame, and a glue gun.

[0011] Preferably, the drying mechanism includes a hot air blower, a hot air duct, and an air outlet.

[0012] Preferably, the exhaust pipe is connected to the workshop exhaust gas purification system.

[0013] (III) Beneficial Effects

[0014] This invention provides a dispensing device for assembling headphones. It has the following advantages:

[0015] (1) The depth of the placement slot is less than the thickness of the headphone shell, which makes it convenient to place and remove the headphone shell.

[0016] (2) The air pump draws air from the position above the seat through the air passage, which can not only help fix the bottom of the shell, but also collect harmful gases. Attached Figure Description

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

[0021] like Figure 1-2 As shown, the headphone assembly dispensing device of this embodiment includes a support frame 1, a lifting dispensing mechanism 2, and a drying mechanism 3. The support frame 1 is provided with a placement seat 4 that cooperates with the lifting dispensing mechanism 2. The placement seat 4 has a placement groove 5, an air passage 6 inside, and a vent hole 7 longitudinally formed on the placement seat 4. The bottom of the vent hole 7 communicates with the air passage 6. A suction pump 8 and a waste gas pipe 9 connected to the air passage 6 are provided on one side of the back of the placement seat 4. The depth of the placement groove 5 is less than the thickness of the headphone shell. This facilitates the placement and removal of the headphone shell and also allows for the collection of harmful gases.

[0022] Furthermore, the lifting dispensing mechanism 2 includes a hydraulic cylinder assembly 201, a lifting block 202, a connecting rod 203, a fixing frame 204, and a glue gun 205.

[0023] Furthermore, the drying mechanism 3 includes a hot air blower 301, a hot air pipe 302, and an air outlet 303.

[0024] Furthermore, exhaust pipe 9 is connected to the workshop exhaust gas purification system.

[0025] Working principle: The earphone shell is placed in the placement slot 5 and glue is applied by the glue dispensing mechanism 2. In order to prevent the glue on the earphone shell from flowing or being blown away, the drying mechanism 3 blows a slow and uniform hot airflow onto the earphone shell.

[0026] The air intake end of the air pump 8 draws air from the inside of the air passage 6 through the exhaust pipe 6. The vent 7 at the bottom of the earphone shell forms a negative pressure, which can adsorb and fix the earphone shell in the placement slot 5. The vent 7 around the placement slot 5 can absorb the flue gas generated during the heating process. The flue gas is discharged through the exhaust end of the air pump 8 and enters the workshop exhaust gas purification system through the exhaust pipe 9.
