Description

TECHNICAL FIELD

[0001] The utility model relates to open earphone plastic forming technical field, concretely is a ear clip ejection jig. BACKGROUND

[0002] In the ear clip production process, the traditional ear clip ejection mode mainly relies on manual operation. This mode has multiple significant problems, which seriously affects the production efficiency and product quality. First, the manual operation mode of taking out ear clips from the middle plate one by one has instability. Due to the error and uncertainty of manual operation, it is difficult to ensure that the ear clips taken out each time can meet the unified standard and quality. This instability not only increases the product rejection rate, but also affects the smooth progress of subsequent processing and assembly. Secondly, the process of taking out ear clips by manual operation has high labor intensity, which can easily cause worker fatigue. Long-term repetition of monotonous taking-out operation can easily cause workers to have problems such as inattention and slow action, thereby further reducing the production efficiency and product quality. In addition, worker fatigue can also cause work accidents, causing unnecessary losses to the enterprise. Therefore, we propose an ear clip ejection jig to solve the above problems. SUMMARY
