A system for fully automatic selection of welding specifications in resistance welding equipment has been developed to address the problem of workers frequently choosing the wrong specifications during manual welding of multiple parts on a single machine in automobile factories. The system incorporates an automatic recognition system for different workpiece materials using the added machine fixture,visual detection system for nuts and bolts,and secondary graphical confirmation to ensure the correctness of specification calling. This system achieves reliable,fully automatic selection of welding specifications in resistance welding equipment and has shown significant effects in improving welding quality for massproduced workpieces,while solving the problem of specification calling errors that can occur with traditional methods involving process charts and code adjustments. This system is particularly suitable for promoting applications in manual welding of multiple parts on a single machine in automobile factories,ensuring correct specification calling and welding quality. 展开更多

With the development of science and technology,the electronic component industry has become more and more extensive,covering circuits,electrical and electrical systems from small to large.Many of these parts have very high requirements for the production process,and the production process requires a certain amount of workshop space.In the traditional production process,soldering is mainly manual welding.With the development of intelligence,impersonality and automation,the design of electronic products will gradually move towards intelligence.In this process,the application and promotion of welding technology is essential.In order to ensure the production of automatic products,this paper studies and discusses the function control problems and solutions of the soldering machine.Loudspeaker(commonly known as loudspeaker)is one of the most widely used electronic devices.With the development of the electronic industry and the change of the market environment,major manufacturers are developing new products to meet the market demand and product performance.In order to meet the needs of a large number of high reliability electronic products with different structures now and in the future,automatic welding technology is required to ensure that the welding quality and reliability have certain advantages. 展开更多

This paper discusses two urgent problems that need to be solved in fully automatic operation(FAO)for urban rail transit.The first is the analysis of safety in FAO,while another is the analysis of efficiency in FAO.Firstly,this paper establishes an operational safety evaluation index system from the perspective of operation for the unique or typical risk sources of the FAO system,and uses the analytic hierarchy process(AHP)to evaluate the indicators,analyzes various factors that affect the safe operation of FAO,and provides safety management recommendations for FAO lines operation to maintain the FAO system specifically.Secondly,taking the Yanfang Line as an example,this paper uses OpenTrack software to analyze the efficiency of FAO operation,and conducts simulation calculations for key links such as the mainline tracking interval,train entry and exit,and return limit interval.The fault impact surface of the FAO trains is simulated and discussed to verify whether FAO can meet the long-term operation requirements of Yanfang Line.Finally,this paper compares the simulation data of FAO on the Yanfang Line with manual operation(MO)to verify the advantages of FAO and guide the engineering construction of subsequent fully automated driving lines. 展开更多

A new fully automatic ^40Ar/^39Ar laboratory with a Thermo Scientific ARGUS VI mass spectrometer has been established in China University of Geosciences (Wuhan). We designed and developed a mini efficient preparation system (80 mL), a CO2 laser for heating samples, a crusher for extracting fluid inclusions within K-poor minerals and an air reservoir (31 L) and pipette (0.1 mL) system. The ARGUS VI mass spectrometer is operated by the Qtegra Noble Gas software, which can control the peripheral accessories, such as pneumatic valves, CO2 laser and crusher through a PeriCon (peripheral controller). The experimental procedures of atmospheric argon ana- lyses, ^40Ar/^39Ar dating by laser stepwise heating and by progressive crushing in vacuo, can be fully automatically performed. The weighted mean of atmospheric ^40Ar/^36Ar ratios is 302.22+0.03 (1σ, MSWD=0.74, n=200), indicating that air reservoir and pipette system and the whole instrument sys- tem are very stable. This laboratory is a successful pioneer example in China to establish a new no- ble gas laboratory with self-made peripheral accessories expect for the mass spectrometer. 展开更多

During assembly process,the miniature part needs to be fixed in its assembly position.In some occasions where adhesive is used,the joining force is not established due to the adhesive curing process,in that case the locking of parts is required.Manual locking is difficult to meet the increasing demand for mass production.To solve this problem and realize fully automatic assembly,a novel gripper module was designed and corresponding locking method was proposed.Thanks to the functional integration,the gripper module is capable of manipulating and locking the part.This module is integrated into the assembly system and plays a crucial role in automatic assembly.The locking method for automatic assembly is based on the integration of the part picking up and the locking unit releasing.After being placed accurately at its desired position,the miniature part can be automatically locked by releasing the locking unit.The innovative structure and mechanism of the gripper module convert the spring force into the locking force of the miniature part,ensuring non-rigid locking and suitable small locking force.Locking principle,flexibility and limitations of the proposed method were clarified in detail.Moreover,an effective compensation strategy was used to achieve accurate and stable pickup of the part,which increased the reliability of the assembly process.During automatic locking,the disturbances to the part due to the eccentric load were analyzed.The effectiveness of the gripper module and proposed method was verified by experiment.Experimental results indicated that the modular system integrated with the gripper module could meet the requirements of fully automatic assembly.Manual locking is replaced by automatic locking,and workers are liberated from tedious manual operations.The improvement of automation level enables assembly equipment to be applied to mass production scenarios. 展开更多
