Description

Technical Field

[0001] The present invention relates to the field of medical sampling brush production equipment, and in particular to an automatic assembly production line for medical sampling brushes. Background Art

[0002] Cervical cancer is one of the most common gynecological malignancies, second only to breast cancer in incidence. In recent years, its incidence has increased, and the incidence is trending toward younger women. In recent decades, cervical cancer screening has been a widely used approach to reduce cervical cancer morbidity and mortality. Cervical cancer screening allows for early detection and treatment of cervical cancer and precancerous lesions. Cervical cancer detected early has a cure rate of up to 80%-90%.

[0003] During cervical cancer screening and other female gynecological examinations, a sampling brush is needed to collect samples from the female cervical epithelial cells.

[0004] At present, the production of medical sampling brushes generally requires workers to manually splice the brush head and brush tube. Before assembly, one end of the brush head is heated. After the heating of one end of the brush head is completed, the heated end of the brush head is inserted into the plastic rod to complete the splicing process of the medical sampling brush. However, manual splicing of medical sampling brushes by workers is inefficient, and the medical sampling brushes manually spliced ​​by workers will be of different lengths. Existing medical sampling brush assembly equipment requires processes such as clamping, electrode heating, feeding, and removal. Traditional technology sets each process linearly, which makes the medical sampling brush assembly machine occupy a large area, and the weight of the whole machine is very heavy, and the transportation and manufacturing costs are high. In addition, the traditional medical sampling brush assembly technology uses manual labor to press the medical sampling brush head onto the support rod, and the assembly process requires a lot of manpower.
