Application of integrated servo motor in TO fully automatic sealing machine

With the rapid development of science and technology, automation equipment is being increasingly used across various industries. In the field of electronic manufacturing, sealing and welding machines are key pieces of equipment whose performance directly affects product quality and output. In recent years, the application of integrated servo motors in automatic sealing and welding machines has gradually attracted attention. This article provides a detailed introduction to the application and advantages of integrated servo motors in automatic sealing and welding machines.

01. Equipment Introduction

Automatic sealing and welding machines are high-precision electronic manufacturing equipment primarily used for sealing chips or devices on substrates. This equipment employs automation technology to achieve efficient and accurate welding operations.

In automatic sealing and welding machines, integrated servo motors play a critical role. An integrated servo motor is a highly integrated, high-precision, and high-efficiency drive device. Compared with traditional separate servo systems, integrated servo motors offer advantages such as smaller size, compact structure, easy installation, and stable operation. Using advanced vector control technology, they achieve precise speed and position control with high energy conversion and utilization efficiency.

02. Application Example

Automatic sealing and welding machines can be used for automatic sealing of TO series packaged products such as TO46 and TO56. They adopt an independent feeding method using baskets on both the base and cap sides, with each basket holding 5 to 8 carriers to improve work efficiency. The equipment uses automatic loading and unloading by robotic arms, a coaxial clamping structure, and precisely controllable welding parameters, effectively improving the yield rate.

To improve production efficiency and product quality, an electronic manufacturing company decided to upgrade its existing sealing and welding machine to an automatic version. During the upgrade, the company introduced integrated servo motors to replace the original separate servo systems. Through precise speed and position control, as well as efficient energy conversion and utilization, the company successfully improved production efficiency and reduced production costs. At the same time, equipment stability and reliability were enhanced, and the failure rate was significantly reduced.

03. Advantages of Integrated Servo Motors

• High integration improves equipment portability: Integrates servo motors, servo drivers, encoders, and controllers into a single unit, significantly reducing equipment size and weight while simplifying wiring and reducing potential failure points.

• Flexibility to meet diverse needs: Supports CANopen/Modbus communication, allowing flexible control and adjustment according to different work requirements.

• High-precision positioning improves measurement accuracy: High positioning accuracy enables precise positioning of mobile equipment.

• Multiple control modes: Supports PP, VM, PV, PT, HM, IP, CSP, CSV, CST standard modes, as well as NiMotion position mode, speed mode, and torque mode.

• High-speed response improves equipment efficiency: Fast response speed enables quick adjustment of equipment angle and position, improving work efficiency and responsiveness.

• Comprehensive alarm function: Can detect hardware faults in a timely manner to avoid affecting system operation; equipped with multiple safety protection functions including overvoltage/undervoltage, overheat, overcurrent, and stall alarms. LED flashing alarm intuitively displays the current status of the motor.
