Application of yellow glue in loudspeaker buzzer by automatic dispensing machine

Speakers, speakers, buzzers and sound enclosures can be coated with automatic dispensing machine or circular dispensing machine, the conventional use of yellow glue as bonding glue, due to coagulation and cost is relatively low, will not affect the sound, especially in line with the sound dispenser products for dispensing, recommend the use of three-axis dispensing machine or circular dispensing machine, mainly to control the cost and machine type suitable.

1, speaker gluing process

The speaker coated with yellow glue is mainly to glue the horn and the shell together, the use of screws is easy to fall off, because the horn is often shaken, and the vibration is easy to loosen the screw, the glue method can also achieve sealing, engineering process: The speaker is placed on the Y axis of the three-axis dispensing machine platform, and the Z axis will move to the set play, and glue will be applied according to the set path to ensure that it is completed in accordance with the requirements.

2, speaker gluing requirements

Speaker is a combination of speaker, plastic shell and circuit board, speaker closely in the plastic shell, in order to maintain the appearance and practicality of the speaker, bonding to meet the fixed, but also to avoid the appearance of noise, so glue than screw better solve the speaker speaker fixed problem, glue technology is mature, not easy to appear dispensing problems, production is very smooth.

3. Yellow glue

Yellow glue is also known as universal glue, often used in plastic and metal or plastic and wood bonding, glue in the pressure barrel at room temperature will not solidify, need to contact the air to solidify, in the speaker gluing process does not need to clean the dispensing valve, only need to replace the dispensing needle can be a very convenient glue.
