In the first half of 2021, China's photovoltaic (PV) industry has maintained rapid growth and continuous expansion while pursuing the goal of Carbon Peak and Carbon Neutral. Without a doubt, there are bright prospects for the industry whilst China achieves its 3060 goal.
As a manufacturer of autonomous mobile robots, Standard Robots is trying to make its mark on the PV industry, attempting to accelerate the automation of the industry. In this case, Standard Robots helped a well-known domestic PV company transport loads automatically by providing 63 AMRs for its entire factory. The company's director said, " After operating stably, Standard Robots’ 63 AMRs are able to successfully replace the manual handling and free the employees for other duties. Not only has it reduced production cost, but it has also greatly improved the productivity and safety of the company.”
- Overall demands
The company needed to use AMR and the upper system to achieve fully automatic transportation of raw materials across the entire factory. This process includes: dispensers to surface texturization, surface texturization to diffusion, diffusion to lasers, lasers to etching, etching to annealing, annealing to PERC（Passivated Emitter and Rear Cell), PERC to rear paste, rear paste to top paste, and top paste to laser slotting.
- Detailed demands
Double-decker driving shelf: length-1450mm, width-880mm , height-1300mm, weight-400kg.
·Automatic transportation of raw materials: AMR transports the double-decker driving shelf to connect with the powerless drive belt which has to convey flower baskets from AMR’s machine station to the next process.
- Stringent positioning requirements
Since the drive belt is powerless, it requires more precision to dock the back gear.
- High handling capacity of AMR
The company has tight production schedule and challenging time constraint of some processes (materials must be delivered within 5 minutes).
- Strict safety requirements
Conditions of on-site operation is complicated in the PV company.
- Strict cleanliness
Workshops in the PV industry are kept very clean but some dust will be generated while AMR operates.
63 Standard Oasis 600C units, several automatic charging piles, 1 manual charger.
Matrix deployment software, FMS scheduling system, Standard central control system
First, Standard Robots provides the latest FMS scheduling system with a navigation accuracy of ±5mm, combined with partial beacons attached to the machine station to achieve the docking accuracy.
Second, Standard Robots optimizes the scheduling system and rationalizes the allocation of cyclic tasks during the pre-design process.
Third, Standard Robots uses double diagonal laser radar for 360° bar code scanning, and cooperates with the vision module to ensure the safety.
Fourth, Standard Robots reduces components that easily produce dust and employs wear-resistant soft wheels to reduce dust produced by friction with the ground.
- Promote the automation of the company
Raw materials handling, loading and unloading are successfully automated to reduce the workload of workers.
- Add benefits for the company
Direct machine-to-machine docking effectively reduces the possibility of material damages caused by falling silicon wafers.
- Promote the IT management of the company
A full information equipment management solution has been employed to monitor AMR status in real time.
- Promote the digitization of the company
The line side cache is effectively controlled to further optimize the site management and accelerate material turnaround.
- Help the company overcome recruitment issues
Recruitment challenges and low reliability of workers are effectively resolved.
To accelerate the PV industry’s development in the new sector, Standard Robots has offered flexible industrial logistics solutions based on its laser SLAM navigation AMR and RIOT management system. In the future, Standard Robots will make every endeavor to boost the automation of companies in kinds of industries.
