Description

Technical Field

[0001] This invention relates to the field of headphone assembly technology, specifically to a fully automatic headphone dispensing device and dispensing method. Background Technology

[0002] Headphones can receive electrical signals from media players or receivers and convert them into audible sound waves using speakers placed close to the ears. Headphones can be detached from media players and connected via plug or Bluetooth, allowing you to listen to audio privately without disturbing others. They can also isolate ambient noise, which is helpful for people using them in noisy environments such as recording studios, bars, travel, and exercise.

[0003] The manufacturing and assembly process of headphones has a significant impact on their lifespan. Adhesive dispensing is a crucial step in this process, currently mostly done manually. However, with technological advancements, the drawbacks of manual methods are becoming increasingly apparent, specifically: 1. Low work efficiency, unable to meet the ever-growing production demands of factories; 2. Low yield rate, as assembly workers require pre-job training, but due to their own cognitive abilities and external factors, the adhesive bonding at the dispensing points is often insufficient, and over-adhesion is also common, compromising the yield rate of assembled headphones; 3. High cost, as labor costs increase with societal development and progress, placing considerable economic pressure on businesses.

[0004] To address the aforementioned issues, a fully automated adhesive dispensing device and method for headphones urgently need to be developed. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic dispensing device and method for headphones, which has the advantages of being fully automatic, highly efficient, and having a fully sealed dispensing process with a high yield rate, thus solving the problems mentioned in the background art.

The inner cavity of the lower sealing cover is fixedly connected with a plurality of lower sealing seats arranged in an evenly spaced ring. The inner cavity of the lower sealing seat is provided with a positioning frame. A connecting frame is fixedly connected at the center of the bottom of the inner cavity of the lower sealing cover. A plurality of lower assembly brackets adapted to the lower sealing seats are fixedly connected to the surface of the connecting frame. Two heat radiation ring tubes arranged vertically are provided through the surface of the lower assembly brackets. A plurality of demolding cylinders adapted to the lower sealing seats are fixedly connected to the bottom of the lower sealing cover. The output end of the demolding cylinder extends through the inner cavity of the lower sealing seat and is fixedly connected to an auxiliary lifting seat. A through hole adapted to the output end of the demolding cylinder is opened at the bottom of the inner cavity of the lower sealing cover.

[0010] Preferably, a fixed base is fixedly connected to the bottom of the dispensing machine body, and a positioning bolt is provided on the top of the fixed base. The dispensing machine body is detachably connected to the upper sealing cover through the positioning bolt.

[0011] Preferably, the top of the dispensing machine body is provided with a circular interface for external delivery of adhesive liquid.

[0013] Preferably, anti-detachment eaves are provided on both sides of the positioning block and in the inner cavity of the telescopic cavity, and the two sides of the anti-detachment eaves are in contact with the inner wall of the telescopic cavity.

[0014] Preferably, the bottom of the positioning block is provided with a limiting groove that is adapted to the earphone shell, and the surface of the limiting groove is coated with a particulate coating.

[0015] Preferably, a support structure is provided on both sides of the lower sealing cover. The support structure includes a transverse load bracket and an auxiliary bracket located on both sides of the lower sealing cover. A base is fixedly connected to the end of the transverse load bracket and the auxiliary bracket away from the lower sealing cover.

[0016] Preferably, both the first and second thermal radiation ring tubes are composed of heating wires, magnesium oxide powder insulating filler, and stainless steel annular outer casing.

[0017] Preferably, an automatic headphone dispensing device further includes an automatic headphone dispensing method:

[0018] Step 1, Loading: The robotic arm places the earphone shell into the inner cavity of the lower sealing seat. During this process, the positioning frame, by its shape, limits the orientation and position of the earphone shell. At this time, the robotic arm loads the speaker assembly and control bracket from the earphone and then lifts it out.

[0019] Step 2, Closing and Dispensing Adhesive: After the robotic arm moves out of the work area, the PLC controller controls the linear guide motor to start. The output end of the linear guide motor drives the cantilever and dispensing part to move downward through the dustproof linkage seat until the upper and lower sealing covers fit together to form a sealed cavity to prevent foreign object contamination. At this time, the dispensing machine body starts and completes the dispensing operation between the speaker assembly and its control bracket through the dispensing tube.

[0020] Step 3, Heat Holding and Pressure Holding: At this time, the output end of the linear guide motor drives the dustproof linkage seat, cantilever and dispensing part to move slightly upward, and the first and second heat radiation ring tubes start in succession, forming a heat radiation field of 80 degrees Celsius-120 degrees Celsius. At this time, the output end of the electric telescopic rod drives the linkage seat to move downward. The linkage seat drives the elastic pressure seat to move downward through the upper mounting bracket and sealing box, fixing the horn assembly and control bracket. At this time, the dispensing tube of the dispensing machine body exits the inner cavity of the sealing box and hangs above to prevent the heat from drying the glue in the dispensing tube. The sealing box and the lower sealing seat fit together to form a relatively sealed cavity. The time is controlled between 5-13 minutes.

[0021] Step 4, Return to Position and Exit: After the drying time is over, the first and second heat radiation ring tubes will close successively, the electric telescopic rod will retract, and the linkage seat, upper assembly bracket, sealing box and elastic pressure seat will return to their original positions. The output end of the linear guide motor will drive the cantilever and dispensing part to move upward, the robotic arm will re-enter the field, the demolding cylinder will drive the demolding lifting seat to move upward, and push the earphone upward to facilitate the robotic arm to grip it. After transfer, the entire dispensing operation is completed.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention utilizes an upper and lower sealing cover, with the entire dispensing process taking place in a sealed space, preventing external environmental contamination of the earphone exterior. After dispensing, a heat radiation field is created using two heat radiation rings to accelerate adhesive coagulation. An electric telescopic rod moves the sealing box downwards, and an elastic pressure seat uses its elasticity to press and secure the speaker assembly and control bracket within the earphone without damaging it, ensuring a strong bond. During this process, the sealing box and lower sealing seat reform into a sealed cavity, completely isolating the external environment and ensuring no external contamination during assembly. This fully automatic dispensing device and method for earphones boasts advantages such as full automation, high efficiency, a completely sealed dispensing process, and a high yield rate. In actual operation, it can be controlled entirely by a computer and PLC controller, minimizing errors and achieving a high yield rate. With the assistance of a robotic arm, it enables rapid dispensing, improving enterprise production efficiency while reducing production costs, and possesses broad application prospects.

[0040] Step 1, Loading: The robotic arm places the earphone shell into the inner cavity of the lower sealing seat 72. During this process, the positioning frame 73 uses its shape to limit the orientation and position of the earphone shell. At this time, the robotic arm loads the speaker assembly and control bracket in the earphone and then lifts it out.

[0041] Step 2, Closing and Glue Dispensing: After the robotic arm moves out of the work area, the PLC controller controls the linear guide motor 3 to start. The output end of the linear guide motor 3 drives the cantilever 5 and the dispensing part 6 to move downward through the dustproof linkage seat 4 until the upper sealing cover 63 and the lower sealing cover 71 fit together to form a sealed cavity to prevent foreign object contamination. At this time, the dispensing machine body 68 starts and completes the dispensing operation between the speaker assembly and its control bracket through the dispensing tube.

[0042] Step 3, Heat Holding and Pressure Holding: At this time, the output end of the linear guide motor 3 drives the dustproof linkage seat 4, cantilever 5 and dispensing part 6 to move slightly upward, and the first heat radiation ring tube 614 and the second heat radiation ring tube 76 are started in succession to form a 90-degree heat radiation field.

At this time, the dispensing tube of the dispensing machine body 68 exits the inner cavity of the sealing box 612 and hangs above to prevent the heat from drying the glue in the dispensing tube. The sealing box 612 and the lower sealing seat 72 fit together to form a relatively sealed cavity. The time is controlled at 12 minutes.

[0043] Step 4, Return to Position and Exit: After the drying time is over, the first heat radiation ring tube 614 and the second heat radiation ring tube 76 are closed in succession, the electric telescopic rod 66 retracts, driving the linkage seat 610, the upper assembly bracket 611, the sealing box 612 and the elastic pressure seat 616 to return to their original positions.

[0044] Example 2: The fully automatic headphone dispensing device of the present invention also includes a fully automatic headphone dispensing method:

[0045] Step 1, Loading: The robotic arm places the earphone shell into the inner cavity of the lower sealing seat 72. During this process, the positioning frame 73, by utilizing its shape, plays a role in limiting the orientation and position of the earphone shell. At this time, the robotic arm loads the speaker assembly and control bracket in the earphone and then lifts it out.

[0046] Step 2, Closing and Applying Adhesive: After the robotic arm moves out of the work area, the computer-controlled linear guide motor 3 starts. The output end of the linear guide motor 3 drives the cantilever 5 and the dispensing part 6 to move downward through the dustproof linkage seat 4 until the upper sealing cover 63 and the lower sealing cover 71 fit together to form a sealed cavity to prevent contamination by foreign objects. At this time, the dispensing machine body 68 starts and completes the dispensing operation between the speaker assembly and its control bracket through the dispensing tube.

[0047] Step 3, Heat Holding and Pressure Holding: At this time, the output end of the linear guide motor 3 drives the dustproof linkage seat 4, cantilever 5 and dispensing part 6 to move slightly upward, and the first heat radiation ring tube 614 and the second heat radiation ring tube 76 are activated in succession to form a heat radiation field of 80 degrees Celsius. At this time, the output end of the electric telescopic rod 66 drives the linkage seat 610 to move downward. The linkage seat 610 drives the elastic pressure seat 616 to move downward through the upper mounting bracket 611 and the sealing box 612, fixing the speaker assembly and control bracket. At this time, the dispensing tube of the dispensing machine body 68 exits the inner cavity of the sealing box 612 and hangs above to prevent the heat from drying the glue in the dispensing tube. The sealing box 612 and the lower sealing seat 72 fit together to form a relatively sealed cavity. The time is controlled at 8 minutes.

[0048] Step 4, Return to Position and Exit: After the drying time is over, the first heat radiation ring tube 614 and the second heat radiation ring tube 76 are closed in succession, the electric telescopic rod 66 retracts, driving the linkage seat 610, the upper assembly bracket 611, the sealing box 612 and the elastic pressure seat 616 to return to their original positions.
