Case Study – Semiconductor Manufacturing
The client has plans to enhance its deployed mobile robots with robotic arms to augment its manufacturing capability to its clean rooms. With its prior floor-mounted contact charging docks designed for the mobile robots, it was unable to support its expected uptime as a result of the significant power drain by the robotic enhancement.
Xnergy offered its Contactless charger with small form factor to allow for easy integrations onto installed line equipment to realise opportunity charging of its robotic armed mobile robots while they do momentary stops to work. This increased uptime while reducing the number of robotic deployment for the same expected throughput.
Outcome #1: Lowered Charging Cost by 47.4%
| Contact Charging | Contactless Charging | |
|---|---|---|
| Mobile robot | 2 units | 1 unit |
| At the cost of | $120,000 x 2 = $240,000 | $120,000 |
| Battery charging station | $1,500 | $1,949 x 6 = $11,694 |
| With an annual maintenance | $1,000 x 2 = $2,000 | $360 x 1 = $360 |
| GRAND TOTAL | $243,500 | $132,054 |
Outcome #2: Improved Operating Efficiency by 100%
It also resulted in a direct comparison of uptime efficiency.
In the case of Contact Charging:
| Uptime after fully charged | 6 hours x 2 units = 12 hours |
| Downtime during charging | 3 hours x 2 units = 6 hours |
| Resulting in total mobile robots’ uptime per day of | 24 hours |
| Plus a total downtime of | 24 hours |
| Uptime Efficiency | 50% |
