1.8. Key Working Station Introduction

(Function and Technological Process Description)

   1. barrel feeding adopts slide rail track vibration add low speed rotary scraper,

guaranteed not to scratch the barrel and feeding in time,

feeding time and quantity can be controlled accurately. 

2. needle feeding can be changed with needle clamp, in order to be suitable for

more syringe specifications. The needle feeding method adopts gravity

free falling into the needle hub, it will not cause the secondary damage 

of the needle the point burr and other parts of this equipment.

 3. The glue(adhesive) feeding adopts dispensing method to make sure the glue is mellow and full.

    4. The drying oven adopts ultraviolet ray constant temperature control module,fully drying the adhesive, to make sure firm and reliability.

    5. CCD image detection the burrs and back needle and glue,it can judge and memorize the defective products fast and accurately,

the accuracy rate is above more than 99%.  

    6. block detecting device adopts sensor chip test mode, accurate and efficient,and not to damage the needle point, effectively solve the difficult monitoring

problem during the automatic assembly process.

   7. When silication, it comes with the function of big and small air blowing,reduce the silicone oil blocking to zero.  

   8. The waste rejection adopts air cylinder one-to-one rejecting method to reject every defective products.

  9. top orange cap pressing adopts one-to-one method to compress.
