With the continuous improvement of the level of experimental automation, higher requirements are placed on the assembly quality, cleanliness and packaging efficiency of pipette tips. Especially in mass production, the traditional manual plugging and manual boxing methods can no longer meet the production requirements of high standards, high rhythm and high consistency. As an intelligent device integrating automatic feeding, automatic positioning, precise plugging and boxing, the automatic pipette tip plugging and boxing machine is becoming a key tool for pipette tip manufacturers to improve quality and efficiency.

　　1. The particularity of pipette tip product assembly

　　Pipette tips are usually made of highly transparent medical polypropylene (PP) material, with the characteristics of precise specifications, high cleanliness and easy deformation. In order to prevent contamination and facilitate access, the pipette tips need to be neatly inserted into the tip rack and packaged in accordance with the specified batches. Manual assembly is not only inefficient and labor-intensive, but also prone to the following problems:

　　The plug core is not straight or tilted, affecting the compatibility of the automated pipette machine;

　　The quantity is uneven and the arrangement is not neat, reducing the product qualification rate;

　　It is easy to cause pollution and does not meet the requirements of GMP or clean workshops;

　　High cost and unstable human resources restrict the expansion of production scale.

　　Therefore, the use of automated assembly equipment is a necessary means to achieve efficient, safe and standardized tip packaging.

　　2. Structure and working principle of automatic plugging and boxing machine for tips

　　The automatic plugging and boxing machine for tips is a special automated equipment for tip products. It is suitable for different types of tips such as 10μL, 200μL, and 1000μL. It automatically plugs the tips into the tip box according to the arrangement specifications and completes the box sealing assembly. Its main components include:

　　Automatic tip feeding system: Use a vibration plate or elevator to automatically straighten and position the bulk tips and transport them to the grabbing area.

　　Automatic conveying system for brackets and boxes: automatically conveys empty tip brackets and tip boxes to designated assembly stations, compatible with a variety of specifications.

　　High-speed picking and plugging mechanism: adopts multi-axis manipulators or servo-controlled suction cups to accurately grab and insert tips at high speed according to the arrangement specifications, with smooth movements and no collisions.

　　Automatic detection and compensation function: equipped with visual recognition or displacement sensors to detect the number of tips, whether they are inserted in place, etc., and has an automatic refilling mechanism.

　　Box sealing and discharging module: automatically completes subsequent assembly actions such as capping, labeling, and filming of the tip box, and conveys the finished product to the packaging section.

　　Intelligent control system (HMI): adopts PLC and touch screen control, which can set production parameters, switch product specifications, display operating status and fault alarms.

　　3. Equipment advantage analysis

　　Efficient production, labor saving: the equipment can complete dozens of boxes of tip plugging operations per minute, with efficiency far exceeding that of manual labor, and multi-shift operation significantly reduces labor costs.

　　Accurate insertion and standard arrangement: The tips are precisely positioned and neatly arranged to ensure perfect docking with the automated pipetting system and enhance the terminal user experience.

　　Clean operation to avoid contamination: The fully enclosed structure design can be placed in a Class 100 or Class 1000 clean room to meet sterile requirements.

　　Flexible compatibility and convenient switching of multiple specifications: By replacing the mold or setting parameters, it can be compatible with tip boxes of different sizes and arrangements to improve the versatility of the equipment.

　　Stable quality and reduced defective rate: Automated operation avoids human errors, greatly improves the qualified rate of finished products, and reduces customer complaints and returns.

　　Expandable MES system connection: Supports data upload, remote monitoring and production traceability, and helps digital management of factories.

　　The automatic plugging and boxing machine for tips is not only an important equipment to improve the efficiency of tip manufacturing, but also a key tool to ensure product quality, enhance corporate brand image and customer satisfaction. It represents an important transformation of the consumables assembly process from "manual operation" to "intelligent manufacturing", which has far-reaching significance for the sustainable development of the laboratory consumables industry.
