Product Introduction
### **Linear Module Product Introduction**
#### **1. Product Overview: What is a Linear Module?**
A linear module, also known as a linear slide, electric slide, or actuator module, is an automated unit that integrates **transmission, guidance, and drive** into a single package. Driven by an electric motor, it precisely converts rotary motion into linear motion, enabling **precise positioning, handling, and reciprocating movement** of a load.
As a core component in automation equipment, the linear module is recognized as a modern solution replacing traditional "cylinder + guide rail" setups. Known for its **high integration, high precision, high rigidity, and ease of installation and maintenance**, it is often hailed as the "robotic arm of the industrial field."
#### **2. Core Advantages & Value**

### **Linear Module Frequently Asked Questions (FAQ)**
---
#### **Part 1: Selection and Design Phase**
**Q1: How should I choose the type of linear module (Screw vs Belt)?**
**A:** This is the most core question, primarily depending on your application requirements:
| Characteristic | Ball Screw Module | Belt Drive Module |
| :--- | :--- | :--- |
| **Accuracy** | **High** (Can reach ±0.01mm) | Medium-Low (Typically ±0.1mm) |
| **Speed** | Medium-Low (Typically ≤1.5m/s) | **High** (Can reach 3-4m/s or higher) |
| **Load Capacity** | **High** (High rigidity, strong load-bearing capacity) | Medium-Low (Belt itself has elasticity) |
| **Noise** | Relatively Lower | Relatively Higher (Belt and wind noise at high speeds) |
| **Cost** | Relatively Higher | Relatively Lower |
| **Primary Applications** | CNC machining, inspection equipment, precision assembly | Laser cutting/marking, material handling, sorting, spraying |
**Simple Summary: For precision and load, choose screw type; for speed and long stroke, choose belt type.**
**Q2: How is the load capacity of a linear module defined?**
**A:** Load capacity typically refers to the **center load** that the module can stably support during movement. It is limited collectively by the guide rails, screw/belt,滑块 (sliders/blocks), and motor torque. When selecting a model, you need to calculate the **weight, center of gravity position, and inertia** of your load, ensuring it falls within the module's dynamic and static load rating graphs, and includes a safety margin (typically 1.5-2 times).
**Q3: What is the difference between Repeatability and Positioning Accuracy?**
**A:**
* **Positioning Accuracy:** The command requests movement to the 100mm position, the overall deviation between the actual arrived position and 100mm.
* **Repeatability:** Executing the command "move to the 100mm position" multiple times, the dispersion between each actual arrived position.
**For most automation applications, repeatability is more important than absolute positioning accuracy.**
**Q4: Do I need to calculate and select the motor and drive myself?**
**A:** Yes, this is a necessary step. You need to perform selection calculations based on the following parameters:
1. **Load Mass** and **Friction Coefficient**
2. **Operating Speed** and **Acceleration**
3. **Transmission Efficiency** (Screw lead or pulley diameter)
By calculating the required **Torque** (to overcome friction, for acceleration) and **Rotational Speed**, you can match the motor and drive. Many suppliers provide selection software which can greatly simplify this process.

#### **Part 2: Installation and Commissioning Phase**
**Q5: What are the most important considerations when installing a linear module?**
**A:**
1. **Base Surface Flatness and Levelness:** This is the most critical! The mounting base must be flat, clean, and sufficiently rigid. Otherwise, it can cause module deformation, accelerated wear, loss of accuracy, and abnormal noise. Always use a dial indicator for alignment and correction.
2. **Belt Tension (for Belt Modules):** The belt requires proper tension. Too loose causes lost steps and poor accuracy; too tight increases wear and motor load.
3. **Coupling Alignment (for Screw Modules):** The connection between the motor and the screw requires good alignment. Using a flexible coupling can compensate for certain deviations.
4. **Cable Management:** Properly secure and protect motor and sensor cables using cable carriers (e.g., drag chains).
**Q6: Why is the module very noisy after installation?**
**A:** Possible reasons include:
* **Uneven Mounting Surface:** Causes the module to be forcibly twisted, creating excessive internal stress on the rails and blocks.
* **Misaligned Coupling:** Misalignment between the motor and screw generates vibration and noise.
* **Insufficient Lubrication:** Lack of lubrication on the blocks or rails.
* **Speed/Acceleration Set Too High:** Especially for screw modules, high-speed operation can produce a whining sound.
* **Excessive Belt Tension:** Generates high-frequency noise.
**Q7: Why is the module's positioning inaccurate/deviating?**
**A:**
* **Mechanical Reasons:** Loose coupling, belt slippage, debris inside the screw/belt, damaged block.
* **Electrical Reasons:**
* **Lost Steps:** Insufficient motor torque or acceleration set too high, causing the motor to fail to respond to all pulses from the controller.
* **Electrical Interference:** Signal cables affected by strong electromagnetic interference, causing pulse loss or corruption.

#### **Part 3: Operation and Maintenance Phase**
**Q8: What kind of routine maintenance do linear modules require?**
**A:**
1. **Regular Lubrication:** Depending on usage frequency and environment, regularly lubricate the rails and screw with the specified grease or oil. This is the most critical measure for extending service life.
2. **Cleaning and Dust Protection:** Use an air gun to remove dust and debris. In harsh environments (e.g., machining, woodworking), always use **protective covers** (bellows covers, steel covers).
3. **Check Fasteners:** Periodically check if mounting screws, coupling screws, etc., are loose.
4. **Check Belt Tension:** (For belt modules) Periodically check belt tension.
**Q9: What is the lubrication interval? What lubricant should be used?**
**A:** The lubrication interval depends on operating speed, load, travel distance, and working environment. General recommendations:
* **Continuous Operation:** Check every 100-220 km of travel or monthly.
* **Intermittent Operation:** Check every 3-6 months.
Always use the lubricant type recommended by the module manufacturer (typically lithium soap-based grease or equivalent).
**Q10: What is the typical service life of a linear module?**
**A:** The life of a linear module is typically measured by its **Rated Life** (L10), which is the travel distance that 90% of a batch of products can achieve. It primarily depends on the life of the linear guide and block. The rated life can be calculated by a formula and is inversely proportional to the load. Under conditions of correct installation, appropriate load, and good maintenance, the life of ball screws and linear guides can typically reach tens of thousands of kilometers or more.

#### **Part 4: Troubleshooting**
**Q11: What causes jerky motion or vibration during module operation?**
**A:**
* **Debris in Rails/Screw:** Dust or chips entering the raceway.
* **Damaged Rails/Block:** Cracked balls or scratched rails.
* **Severe Lubrication Deficiency:** Causing dry friction.
* **Motor Tuning Issues:** Improper drive parameters (e.g., PID gains) causing system instability.
**Q12: What to do if the motor overload alarm triggers?**
**A:**
1. **Check Mechanical Parts:** Is there a jam? Is lubrication sufficient? Has the load suddenly increased?
2. **Check Drive Parameters:** Is the current (torque) limit set too low? Are the acceleration/deceleration times too short?
3. **Check Power Supply Voltage:** Is the voltage stable and within the rated range?
**Q13: Origin signal/Limit signal failure?**
**A:**
1. **Check Sensors:** Is the proximity sensor or photoelectric sensor damaged? Are the connections secure?
2. **Check Position:** Is the sensor's sensing distance appropriate? Is the dog/target within the sensing area?
3. **Check PLC/Controller:** Is the input point functioning correctly? Is the program logic correct?
**Q76: How to determine if it's a mechanical or electrical problem?**
**A:** A simple **Isolation Method**:
* With the **power off**, try to move the slide by hand (for screw modules, you may need to release the motor brake or coupling).
* If it feels **smooth with uniform resistance**, the mechanical part is likely fine.
* If it feels **sticky, has noticeable bumps, makes noise, or is very heavy**, there is likely a mechanical problem.
If the mechanical part is normal, the problem likely lies with the motor, drive, or control system.
