SEER Intelligent Logistics Solution for Pneumatic Component Processing Workshop
Background of the project
With the comprehensive advancement of a new round of technological revolution, in the global manufacturing system, production automation and the realization of intelligent internal logistics have become one of the most concerned topics for many manufacturers. At the same time, it is also an important issue that needs to be resolved in each plant workshop. Especially for some powerful large-scale enterprise workshops, as production automation matures gradually, the solution of internal logistics automation and intelligent will become the next threshold for building smart factories, which is of great significance for achieving efficient and lean production.
Customer issues
The customer is a foreign-owned company and a world-renowned manufacturer of pneumatic and electric components, components and systems. In the pneumatic component production workshop of a branch in North-China, due to the need to frequently changing the processing site for semi-finished products, the internal logistics transportation through traditional human transportation is not only inefficient, but also not conducive to the realization of plan production information. To comply with the current wave of intelligent manufacturing development and achieve a high degree of information and automation, the customer tried to introduce a complete set of intelligent logistics solutions to solve the problem of docking and storage and production line automation.
SEER solutions
According to the customer's on-site situation, SEER assisted the integrator to implement the logistics automation transformation of the factory floor. The complete set of solutions, including AMB-powered jacking roller robot, AMB-powered jacking robot, ground roller line, calling PDA, SEER Enterprise Enhanced Digitalization MP (SEED), etc., helped the customer to realize the logistics automation and intelligence in the warehouse and plan.
There are two areas, warehouse and production line, in the customer's site. The raw materials in the warehouse (blank area) need to be transported to the workshop production line. In the workshop production line, there are currently 9 workstations, each of which has 2 rollers (one in and one out), including the blank preparation station, processing area 1, processing area 2, processing area 3, and processing area 4, deburring station 1, deburring station 2, measuring station, cleaning station, needing to use mobile robots for production line docking.
The user's MES system is connected through SEED, and is equipped with a calling PDA in the warehouse delivery area and production line station. The AMB-powered jacking robot completes the material transportation between the warehouse and the production line and AMB-powered jacking and roller robot completes the production line docking in the workshop.
In the warehouse area, a worker puts a package of goods on the rack, and then scans the picking list, the delivery area, the QR code of the rack, and the employee code for information entry; after completion, calls the AMB-powered jacking robot via PDA to pick up. After the picking task order is generated, SEED will determine whether there is a vacancy in the production line station. If there is a vacant order. If there is a vacancy, the order will be executed. If there is no vacancy, the order will be suspended. After the order is suspended, the warning light is on and the PDA is used to indicate that there is an empty rack in the production line. After the empty rack is removed, the order continues to be executed.
In the production line area, the AMB-powered jacking roller robot completes the production line docking of the blank preparation area, processing area, deburring area, measuring area and cleaning area. Due to the different heights of the roller lines at the customer's on-site, the AMB-powered jacking roller robot can adjust the height according to the production line station to flexibly complete the task of production line docking.
Difficulties in implementation and countermeasures
Difficulties
  1. At present, the user does not have a WMS system, and it is impossible to detect whether there are vacant positions in the warehouse position and the production line station.
  2. The user’s needs are more complex, requiring different types of robots to work together and cooperate with each other.
  3. Due to great mobility in the workshop, comprehensive detection mechanisms and early warning mechanisms are required to ensure transportation safety.

Countermeasures
  1. SEED has realized the monitoring of global logistics information, which can implement the inspection of warehouse locations and production line stations and timely feedback.
  2. SEER dispatching system can satisfy the unified scheduling of hundreds of different types of mobile robots at the same time, and solve the problem of multi-type mobile robots working together.
  3. In this implementation, a dual-laser mobile robot and a comprehensive alarm mechanism are used to achieve 360 ° comprehensive detection, ensuring transportation safety and improving transportation efficiency.
Benefits to customers
  1. Realized the automation and intelligence of warehouse and workshop logistics, improved transportation efficiency and greatly reduced labor costs and personnel management costs for the factory.
  2. Closely connected with the MES system, greatly improving the level of workshop automation and intelligence.
