Description

Technical Field

[0001] The invention relates to the technical field of plastic shell manufacturing, and in particular to a glue dispensing device for a smoke alarm shell. Background Art

[0002] Smoke alarm is actually another name for smoke detector or smoke alarm. Smoke alarm achieves fire prevention by monitoring the concentration of smoke. It uses ion smoke sensor inside. Ion smoke sensor is a technologically advanced sensor with stable and reliable operation. It is widely used in various fire alarm systems and its performance is far superior to gas sensitive resistor type fire alarm.

[0003] When manufacturing smoke alarms, some components or the housing itself will be fixed and connected by dispensing glue. The dispensing connection not only simplifies the connection of the housing and components, but also improves production efficiency. During the production process, the existing dispensing device has a systematic fixing device for fixing, a dust removal device for dust removal, and then rotates through a rotating device. Then, the dispensing needle is used for dispensing glue. After the dispensing is completed, the gripping device is used to grab and shift. At this point, the dispensing work is completed. The entire process only requires manual fixing, which is very efficient and the production quality is also very high.

[0004] However, in actual use, after vacuuming, the shell still needs to travel a certain distance to reach the dispensing station, and the shell will be contaminated again during this process. After dispensing, the shell will travel a distance again before entering the engagement station. This distance will also cause the dispensing to be contaminated by dust or debris, and the long waiting and working time of the dispensing needle will cause the needle to be blocked or the needle to accumulate, which not only affects the accuracy of dispensing, but also reduces the quality of dispensing.
