Project Objectives
The project required an automated cell for fastening the lower cover, upper cover, upper sealing plate, and side sealing plate to an enclosure body. The line needed to coordinate component supply, robotic handling, enclosure positioning, screw fastening, and finished-part transfer.
AGVs were planned to deliver the enclosure and the four component types to dedicated staging positions around the robotic cell. The supplied design specifies 70 pieces per carrier for the lower cover, upper cover, and side sealing plate, and 140 pieces per carrier for the upper sealing plate.
The specified target was a design throughput of 600-800 pieces per hour with one planned operator, supported by PLC, touchscreen, and industrial-computer control.
- Automate enclosure and panel feeding through dedicated AGV supply points.
- Use robotic handling and position calibration to prepare components for assembly.
- Complete screw fastening with two four-axis screwdriving robots.
- Transfer completed enclosures through a speed-chain conveyor.
Our Solution
The proposed system places AGV material stations around a guarded robotic cell. A six-axis robot handles the enclosure and component panels, while a dedicated calibration station establishes repeatable pickup and assembly positions. The enclosure is clamped at a rotary fixture so different fastening surfaces can be presented to two four-axis screwdriving robots.
After the screwdriving sequence is completed, the enclosure is transferred out of the cell through the speed-chain conveyor. PLC, touchscreen, and industrial-computer control coordinate robot motion, fixture actions, material flow, and the operating sequence.
Process Flow
AGVs deliver the enclosure and component panels to their assigned staging positions. The six-axis robot picks and transfers the materials through the calibration and assembly sequence. The enclosure is secured at the rotary fixture, where four-axis screwdriving robots A and B complete programmed fastening operations. The finished enclosure then exits through the speed-chain conveyor.
System Configuration
The cell integrates five AGV supply points, one six-axis handling robot, two four-axis screwdriving robots, a component calibration station, a rotary enclosure fixture, and a speed-chain output conveyor
Key Equipment Solutions
The following equipment functions are derived from the supplied process and structure diagrams.
| No. | Equipment Solution | Role in the System |
| 1 | AGV-Fed Material Supply | Delivers enclosures, bottom covers, top covers, upper sealing plates, and side sealing plates to their designated loading stations. |
| 2 | Six-Axis Handling Robot | Picks the enclosure and assembly components from the AGV stations and transfers them to the positioning and assembly stations. |
