What is a Mounting Machine?

A mounting machine is a specialized piece of equipment designed to securely attach or “mount” components onto a substrate, such as a printed circuit board (PCB). These machines are essential in industries where precision and efficiency are paramount, such as electronics manufacturing, automotive, and aerospace. Mounting machines can handle a variety of tasks, including placing surface-mount devices (SMDs), through-hole components, and even more complex assemblies. They are often automated to ensure high-speed, accurate placement of components, reducing human error and increasing production throughput.

Key Components and Structure of a Mounting Machine

Mounting machines are complex systems composed of several key components that work together to achieve precise component placement. Here are the main parts:

1. Feeder System: This component holds and supplies the components to the machine. It can be tape, tray, or stick feeders, depending on the type of components being mounted.
2. Pick-and-Place Head: The heart of the machine, this part picks up components from the feeder and places them onto the substrate. It often includes a vacuum nozzle or gripper for handling delicate parts.
3. Vision System: High-resolution cameras and sensors ensure that components are correctly aligned and placed. This system is crucial for maintaining accuracy, especially with miniaturized components.
4. Conveyor System: This moves the PCBs or other substrates through the machine, ensuring a continuous workflow.
5. Control System: The brain of the machine, often a computer or PLC (Programmable Logic Controller), which manages the entire operation, from component picking to placement.
6. Nozzle Changer: Some advanced machines have an automatic nozzle changer to handle different component sizes and shapes without manual intervention.

How Does a Mounting Machine Work?

Mounting machines operate through a series of well-coordinated steps to ensure precise component placement. Here’s a step-by-step breakdown of how they work:

1. Component Feeding: The feeder system supplies components to the machine. Depending on the type of feeder, components are either rolled out on tape, picked from trays, or fed from sticks.
2. Component Picking: The pick-and-place head moves to the feeder location, where it uses a vacuum nozzle or gripper to pick up the component.
3. Component Inspection: The vision system inspects the component to ensure it is the correct type and orientation. If any discrepancies are found, the component is rejected.
4. Component Placement: The head moves to the designated location on the substrate and places the component with precision. The vision system may perform a final check to ensure accurate placement.
5. Substrate Movement: The conveyor system moves the substrate to the next position, ready for the next component to be placed.
6. Repeat: The process repeats until all components are placed on the substrate.

Mounting Machine Workflow and Process Steps

The workflow of a mounting machine is designed to maximize efficiency and accuracy. Here’s a detailed look at the process steps:

1. Preparation: Load the components into the feeder system and the substrates onto the conveyor.
2. Setup: Configure the machine settings, such as component type, placement location, and speed, via the control system.
3. Feeding: The feeder system supplies components to the pick-and-place head.
4. Picking: The head picks up the component using a vacuum nozzle or gripper.
5. Inspection: The vision system checks the component for correct type and orientation.
6. Placement: The head places the component onto the substrate at the precise location.
7. Verification: The vision system may perform a final check to ensure accurate placement.
8. Movement: The conveyor system moves the substrate to the next position.
9. Completion: The process repeats until all components are placed, and the substrate is ready for the next stage of production.
