10-Piece Fully Automatic Eyelash Brush Assembly Machine

Product Overview

The Eyelash Brush Assembly Machine is designed for assembling brush heads with plastic handles used in mascara brushes, eyelash brushes, cosmetic applicators, eyebrow brushes, and other beauty-care products.

According to the required production capacity, eyelash brush assembly equipment can generally be divided into two categories:

• Single-piece semi-automatic assembly machine
• Multi-piece fully automatic assembly machine

The multi-piece model can be designed to assemble 2, 4, 5, 8, or 10 brushes per cycle. This product page mainly introduces our 10-piece fully automatic Eyelash Brush Assembly Machine, which can assemble ten brush heads and ten handles simultaneously.

The machine must work together with a Brush Head Tray Loading Machine. The tray loading machine first arranges loose and randomly oriented brush heads into a plate in the correct direction and sequence. The assembly machine then picks up one complete row of brush heads from the plate and completes automatic handle feeding, heating, insertion, assembly, and finished-product discharge.

This Mascara Brush Assembly Machine has a production capacity of up to 8,000 pieces per hour, making it suitable for cosmetic brush manufacturers requiring stable, continuous, and high-volume production.

Difference Between Single-Piece and Multi-Piece Assembly Machines

Single-Piece Assembly Machine

The single-piece Cosmetic Brush Assembly Machine is a semi-automatic machine.

An operator manually places or inserts one brush head into the loading position. The machine then assembles one brush head with one handle during each cycle.

This model is suitable for:

• Small production quantities
• Product testing
• New product development
• Factories with lower automation requirements
• Customers with limited initial investment
• Products that change frequently

Because one operator must continuously load the products, the single-piece machine still depends on manual labor.

Multi-Piece Assembly Machine

The multi-piece Makeup Brush Assembly Machine is a fully automatic system.

It can be designed for:

• 2 pieces per cycle
• 4 pieces per cycle
• 5 pieces per cycle
• 8 pieces per cycle
• 10 pieces per cycle

The number of brush heads arranged in each row of the plate must match the number assembled during each cycle.

For example:

• A 10-piece assembly machine requires 10 brush heads in each plate row.
• A 5-piece assembly machine requires 5 brush heads in each plate row.
• An 8-piece assembly machine requires 8 brush heads in each plate row.

The plate layout, gripper quantity, handle-feeding track, assembly fixture, and output system must therefore be designed as one coordinated production system.

The 10-piece Beauty Brush Assembly Machine described here is a fully automatic solution developed for customers requiring higher production capacity and reduced labor dependence.

Brush Head Tray Loading Machine

Before entering the assembly process, loose brush heads must be arranged in the correct direction and order.

Brush heads are normally supplied in a mixed and disorganized condition. Because they are lightweight, flexible, and difficult to orient consistently, they cannot always be fed directly into a multi-piece assembly station.

The Brush Head Tray Loading Machine solves this problem by automatically arranging the brush heads into customized plates.

Its main functions include:

• Receiving loose brush heads
• Identifying or controlling brush-head orientation
• Arranging the brush heads in a fixed direction
• Placing them into the plate one by one
• Maintaining equal spacing between products
• Creating complete rows for robotic pick-up

For the 10-piece Mascara Wand Assembly Machine, each plate row contains ten brush heads. The spacing between the brush heads corresponds exactly to the spacing of the ten-position robotic gripper.

This design allows the assembly machine to pick up ten brush heads simultaneously without requiring manual sorting.

---

Working Process of the 10-Piece Assembly Machine

Step 1: Brush Heads Are Arranged in the Plate

The Brush Head Tray Loading Machine places the loose brush heads into the plate according to a fixed direction and sequence.

Each plate is customized according to:

• Brush-head length
• Brush diameter
• Metal-rod diameter
• Brush-head shape
• Product spacing
• Gripper dimensions
• Number of products assembled per cycle

For this machine, the plate contains ten brush heads in each row.

Step 2: Ten Brush Heads Are Picked Up

The robotic gripper moves to the plate-loading position and picks up ten brush heads at the same time.

The gripper must hold all ten products securely without damaging the fibers, deforming the brush heads, or changing their orientation.

Customized gripper fingers are designed according to the customer’s product samples.

The gripper then transfers the ten brush heads to the central assembly station.

Step 3: Automatic Handle Feeding

Plastic handles are loaded into a vibratory bowl feeder.

The vibratory bowl automatically:

• Sorts the handles
• Controls their direction
• Separates overlapping parts
• Transfers them through the linear feeding track
• Supplies ten handles to the central assembly station

Sensors monitor the presence of each handle. The machine only begins the assembly cycle after confirming that all required brush heads and handles are correctly positioned.

Step 4: Handle Positioning

Ten handles are placed into the customized fixture at the central workstation.

The fixture controls:

• Handle spacing
• Handle direction
• Handle height
• Assembly position
• Product stability

The center-to-center distance between the handles corresponds to the spacing of the ten brush heads in the plate and robotic gripper.

This coordinated design helps ensure that all ten products can be assembled simultaneously.

Step 5: Controlled Flame Heating

Before insertion, the upper end of each plastic handle is heated by a controlled flame-heating system.

The purpose of this process is to soften or slightly melt the handle’s insertion area so that it can be fitted smoothly and securely onto the brush-head rod.

The heating process helps solve several common assembly problems, including:

• Excessive insertion resistance
• Handle cracking
• Brush-head rod bending
• Incomplete insertion
• Uneven insertion depth
• Loose connection after assembly
• Damage caused by excessive pressing force

Important heating parameters can be adjusted according to the plastic material and product structure, including:

• Flame position
• Heating distance
• Heating time
• Heating intensity
• Handle rotation, when required
• Delay before insertion

The heating system must be carefully adjusted to soften the handle without causing excessive melting, burning, discoloration, or deformation.

Step 6: Ten Brush Heads Are Assembled

After heating, the robotic system accurately aligns the ten brush-head rods with the ten softened handle openings.

The machine then completes the insertion and assembly process.

The assembly station controls:

• Insertion direction
• Insertion depth
• Insertion speed
• Pressing force
• Holding time
• Product alignment

All ten brushes are assembled during the same machine cycle.

This synchronized assembly method provides much higher efficiency than single-piece or manual assembly.

Step 7: Cooling and Position Stabilization

After insertion, the assembled products may remain in the fixture briefly to allow the heated plastic to cool and stabilize.

This helps ensure a firm connection between the brush head and the handle.

The cooling or holding time can be adjusted according to:

• Handle material
• Heating temperature
• Insertion depth
• Product dimensions
• Required connection strength

Step 8: Finished-Product Transfer

After assembly is completed, the robotic arm picks up the ten finished eyelash or mascara brushes.

The products are transferred to the output station.

The output system can be customized as:

• Conveyor output
• Collection tray
• Finished-product box
• Plate collection
• Connection with inspection equipment
• Connection with packaging equipment

Production Capacity

The production capacity of the 10-piece Eyelash Brush Assembly Machine is approximately:

8,000 pieces per hour

Actual production speed depends on several factors:

• Brush-head structure
• Handle material
• Required heating time
• Insertion depth
• Product dimensions
• Feeding stability
• Plate replacement time
• Inspection requirements
• Output method

Because ten products are processed simultaneously, the machine provides substantially higher output than a single-piece semi-automatic machine.

This machine is particularly suitable for factories producing large quantities of standardized mascara brushes or cosmetic applicators.
