In industrial production, there are often many complex parts that require lifting and assembly, but manual labor has its limitations. This is where power assist robots come in to help us accomplish these tasks and make our work more efficient.

Today we will talk about how power assist robots handle these complex parts.

Product Used: Hard-arm Power Assist Robot

Case: Handling and assembly of conductive channel components in arc extinguishing chambers

Figure 1：Conducting Channel Assembly on Arc Extinguishing Chamber

The conventional assembly of the conducting channel assembly on the arc extinguishing chamber is as follows

• Traditional assembly of conductive channel components in arc extinguishing chambers involves multiple workers working together to lay long pole components down from a "vertical posture" to a "horizontal posture".
• Then, the tail end is hung by a rope, lifted by an electric hoist and hooked onto the rope buckle.
• The electric hoist lifts the long pole slowly from a "horizontal posture" to a "downward suspended posture".
• Once it reaches a sufficient height, it is slowly inserted into the ceramic bottle.

However, the problem is that during the insertion process, the vertical posture cannot be guaranteed, often resulting in scratches and damage to the components.

In order to reduce the number of workers and lower labor costs while ensuring product quality, the company introduced a power assist robot to complete this complex task. Let's take a look at the performance of the power assist robot.

Functional Performance

Assembly station, the main role of the power manipulator system

Remove the arc extinguishing chamber component (upper conductive channel) from the conveying line, turn it over 180 degrees, and invert the assembly into the high-pressure porcelain bottle to realize labor-saving operation in the whole handling and assembly.

Functional Performance 01

The hard-arm power assist robot has a special gripping mechanism with special materials inside the gripper. Even if the gripping surface of the component is small and smooth, it can still grip the material better, preventing it from falling and being damaged.

Functional Performance 02

The hard-arm power assist robot uses a power gripping mechanism with a special flipping mechanism to achieve 180-degree flipping of the components.

Functional Performance 03

Before assembly, the components need to be inspected, causing them to pause in a horizontal posture. However, the power assist robot can still grip the components tightly, keeping them safe and stable.

Functional Performance 04

When facing extra-long components (1300~1550mm) that require a large flipping space, after flipping 180 degrees, the component needs to be lifted again to pass over the highest point of the ceramic bottle before being inserted into the bottle. The difference between the lowest point and the highest point is more than 2500mm. Throughout the entire process, the operator cannot let go of the control handle, but the hard-arm power assist robot can use its rigid arm to carry the component over obstacles, and the horizontal arm can also meet the requirements for lateral insertion and removal of materials in related areas, perfectly solving the problem.

Functional Performance 05

The product system can always keep the robot's head level, providing high operational efficiency. It ensures that the gripping surface remains horizontal after flipping 180 degrees, with the assembly surface fitting perfectly, without interfering with the assembly surface.

Weightless handling and rigid arms are the two major advantages of the hard-arm power assist robot, making it widely used in complex assembly applications that require overcoming obstacles, precise positioning, restricted states, flipping angles, torsional stress, and special process requirements.
