Device used for dispensing balanced armature earphone receiver

Abstract

The invention relates to a device used for dispensing a balanced armature earphone receiver. An X-axis transmission unit is installed on a rack; a platform passageway is arranged on a slide block of the X-axis transmission unit; a Y-axis transmission unit is arranged above the platform passageway; a Z-axis transmission unit is installed on a slide rail of the Y-axis transmission unit; a positioning and clamping mechanism is installed on a slide rail of the Z-axis transmission unit; a first camera is arranged on the positioning and clamping mechanism; a constant temperature mechanism is also installed on the slide rail of the Z-axis transmission unit; a dispensing head is connected with the lower part of the constant temperature mechanism; and a second camera is arranged above sides of the platform passageway. The device provided by the invention realizes high-precision position dispensing, constant temperature control and high-precision camera monitoring, and obviously reduces reject ratio and reprocessing rate of products.

Description

technical field [0001] The invention relates to a film welding device for a receiver, in particular to a device for dispensing glue for a moving iron earphone receiver. Background technique [0002] Moving iron earplugs generally have a good sound insulation effect, and the extremely high sensitivity enables a small volume to perform well, so you can enjoy pure sound without increasing the volume in a noisy environment, and moving iron earphones Helps to protect hearing, so the moving iron unit is widely used in medical, health care, aviation, military and other fields. The more common ones are hearing aids and high-end music headphones. Doctors will not recommend products that may damage their health to patients, and basically well-known hearing aid brands are using moving iron units, so moving iron earphones are more reassuring to use than moving coil earphones. [0003] The working principle of the moving iron earplug is that the moving iron earphone is transmitted to th...

Problems solved by technology

[0004] The existing method is to reduce the diameter of the dispensing head and require the operator to manually dispensing glue under the microscope, which requires very high proficiency and concentration of the operator. The glue temperature is controllable, too much glue will flow out to the coil and other components, resulting in vibration distortion, too little air leakage, so the failure rate and rework rate are very high
