What should be done when the customer's factory workshop environment is complex and the existing standard AMR cannot meet its intelligent needs?
Based on the rich partner model library of SEER, a large number of non-standard car bodies are available for integrators to refer to. If there is an AMR that meets the needs, quick manufacturing can be carried out directly based on the corresponding model.
If not, the integrator can manufacture the AMR by itself based on the SEER SRC series core controllers. So in this case, is there an easier and faster solution?
Of course there is! SEER AMB series unmanned handling chassis is the best choice.
In summary, although the customer's demand for AMR is non-standard, the demand for the AMR chassis is relatively standard. So, the customer can choose to directly purchase the chassis and expand various upper-level mechanisms on the basis of the chassis, which is more time-saving and energy-saving compared with manufacturing AMRs independently.
▲ Some vehicle manufacturing examples based on the AMB chassis
Following the product development concept of "Supporting Non-standard Applications with Standardized Products", SEER extracts standard products from non-standard requirements and launches the AMB series of unmanned handling chassis by docking with a large number of integrators' vehicle manufacturing projects and summarizing service experience.
This is a general-purpose chassis specially designed for AMR applications. It provides core positioning and navigation, safety obstacle avoidance, and other functions for AMR applications, and provides a wealth of I/O, CAN, and other expansion interfaces for carrying various upper-level mechanisms on the chassis. Together with SEER system software, it can help integrators quickly complete the construction and application of various non-standard mechanisms, and easily cope with various special scenarios.
There are four mounting holes on the top of the AMB chassis to facilitate the expansion of various upper-level mechanisms, including jacking, rollers, manipulators, latent traction, PTZ, etc., so as to achieve multiple applications on one chassis. In the following, we will introduce the mechanisms with the most expanded types of AMB chassis in combination with actual industry scenarios.
The working principle of the jacking mechanism is that the transmission assembly on the frame body rotates under the drive of the drive module to drive the cam to rotate, so as to lift up or down the jacking plate to carry heavy loads.
The roller mechanism refers to a cylindrical rotatable object in the machine. It is the power source commonly used in the machine, such as a motor-driven roller, that drives other materials forward.
In a pneumatic component production workshop in North China, due to the need to frequently change the processing site for semi-finished products, traditional human transportation is not only inefficient, but also not conducive to realizing the informatization of workshop production. In order to achieve a high degree of informatization and automation, the workshop tries to introduce a complete set of intelligent logistics solutions to solve the problem of automatic docking between warehousing and production lines.
According to the actual situation on site, SEER assists the integrator in formulating the logistics automation transformation plan of the workshop, and proposes to introduce the AMB-based jacking roller robots and the AMB-based jacking robots.
The AMB-based jacking robot is used to complete material transportation between the warehouse and the production line. In the production line area, the AMB-based jacking roller robot is used to complete the production line docking of the blank preparation area, processing area, deburring area, measurement area, and cleaning area. Because the heights of the roller line at the customer sites are different, the combination of roller and jacking is used. The AMB-based jacking roller robot can adjust the height according to the station of the production line, and flexibly complete the production line docking task.
The workshop does not have a WMS system, so it is impossible to detect whether there are vacancies in the warehouse and the production line. Moreover, the logistics requirements for vehicles are relatively complex, which requires different types of robots to work together and cooperate with each other, and meanwhile needs to ensure the robot transportation safety in a complex environment.
Through RDS and MWMS software, SEER can realize the unified scheduling of the robots equipped and the overall logistics information monitoring of the workshop, implement the detection of warehouse locations and production line stations, and provide timely feedback to ensure transportation safety and improve transportation efficiency.
The traction mechanism is similar to a locomotive, and requires a mechanism to connect with the rear compartment (towed equipment) to control the traction mechanism. Its latent characteristics mean that the overall structure is low, so that it can easily drill into the bottom of the material to achieve flexible movement.
There are three production areas and a large warehouse in an electronic manufacturing production workshop. In the past, manual forklifts were used to complete the material transportation between the warehouse and the production area, which is of large work amount and low efficiency, and also prone to potential safety hazards. Therefore, it is urgent to realize the logistics automation between the warehouse and the production area.
When assisting the integrator in formulating the overall solution, SEER proposes to introduce AMB-based latent traction robots to assist in realizing the transportation automation between the warehouse and the production area.
Installing PDA pagers in each production area can ensure that when there is a handling demand at the loading and unloading points of the production line, the demand order can be issued in a timely manner according to the storage location results, and then a latent traction robot can be selected to perform the traction task, thus completing the handling requirement between the warehouse and the workshop, and between the production lines in the workshop.
The narrow fixed passages, great change of the dynamic environment in some areas, and high staff mobility of the workshop can easily lead to a series of unpredictable dangerous situations such as collisions and deadlocks. The SEER robot has the basic function of autonomous and intelligent obstacle avoidance, so that it can effectively avoid pedestrians. At the same time, it uses reflectors to assist positioning in high-dynamic areas to ensure that the robot positioning will not be lost.
In order to meet the needs of partners going overseas and meet the European Union's safety standards, SEER launched an upgraded version of the AMB unmanned handling chassis AMB-300XS at the end of 2022, with a built-in safety controller SRC-3000FS, with which the safety protection was upgraded. In addition, it passed the ISO CLASS4 cleanliness test, so it can be directly used in industries with high cleanliness requirements such as semiconductors.
The emergence of standard chassis directly lowers the threshold for AMR manufacturing, and lays a technical foundation for the wider application of AMR to various industries and scenarios. In the future, SEER will continue to optimize the technical support of AMB chassis and explore chassis applications for more subdivided scenarios and tracks, so as to contribute to the ecological construction of AMR.
