1. Introduction
A cam divider is an important part of many automated systems, especially in tape and reel machines, which are used to package small components like IC chips and electronics. The cam divider helps control both speed and accuracy in these machines. In this article, we will explain how cam dividers work, how they affect the speed and accuracy of machines, and how to choose the right one.
2. What is a Cam Divider?
A cam divider is a device that turns continuous spinning into precise, timed movements. It consists of:
1. Input Cam:
The part that provides the spinning motion.
2. Indexing Disc:
This part moves in fixed intervals to control the machine’s movement.
3. Rollers:
These roll over the indexing disc to ensure the machine positions parts correctly.
Cam dividers are used in automated machines where precise movements and timing are needed, such as in tape and reel systems, labeling machines, and other production equipment.
3. How Cam Dividers Affect Speed
The cam divider controls the speed of a machine. A faster cam divider can help increase production speed. However, if the cam divider spins too quickly, it may affect the accuracy of the machine. Therefore, it’s important to find the right balance between speed and precision. The factors that affect the speed are as follows:
1. Input Speed:
The speed at which the input shaft turns affects how fast the cam divider operates. In high-speed production, it’s important to keep the input speed steady for smooth operation.
2. Cam Design:
The design of the cam can also affect how quickly the machine can run without losing accuracy.
Example: High-Speed Tape and Reel Machines
In tape and reel machines, cam dividers are used to place components like IC chips onto carrier tapes. To keep up with high production speeds, cam dividers must work quickly. However, if they go too fast, the components may not be placed correctly. It’s important to choose a cam divider that offers the right balance of speed and accuracy.
4. How Cam Dividers Affect Accuracy
Accuracy is critical because the cam divider must position parts correctly every time. In tasks like packaging electronics, even small errors can affect the quality of the final product.
5. How to Choose the Right Cam Divider
When choosing a cam divider, consider the following factors:
Speed Requirements
If your production line runs at high speeds, you’ll need a cam divider that can keep up. But make sure that higher speed doesn’t affect accuracy.
Accuracy Requirements
If your task requires high precision, choose a cam divider with excellent accuracy and repeatability. Some cam dividers offer very fine accuracy, which is ideal for jobs like packaging electronics.
Compatibility
Make sure the cam divider is compatible with other parts of your system, such as servo motors, controllers, and other machinery. Proper compatibility ensures smooth, efficient operation.
6. Maintenance of Cam Dividers
To keep the cam divider working well, regular maintenance is necessary. Here are a few tips:
1. Lubrication:
Regular lubrication helps reduce friction and wear, which helps maintain both speed and accuracy.
2. Wear Checks:
Periodically check the rollers and indexing discs for wear. Replace any parts that are damaged to keep the system running smoothly.
3. Calibration:
You may need to calibrate the cam divider periodically to ensure it continues to operate accurately.
7. Conclusion
Cam dividers play a crucial role in automated systems, affecting both speed and accuracy. In tape and reel machines, they help place components correctly while allowing the system to run at high speeds. By selecting the right cam divider based on your speed and accuracy needs, and by maintaining it properly, you can keep your production line running smoothly and efficiently. As technology advances, cam dividers will continue to improve and help meet the growing demands of industrial automation.
