The invention discloses an automatic material handling system. The automatic material handling system comprises a machine, a rail structure, at least one transport trolley and a master control unit. A wireless signal emitter and a wireless signal receiver are arranged on the transport trolley. The automatic material handling system is further provided with a plurality of wireless signal transmitting-receiving stations and the wireless transmitting-receiving stations are in signal connection of the transport trolleys within the signal range. Through the arrangement of the wireless signal transmitting-receiving stations, all the transport trolleys within the signal range of each wireless signal transmitting-receiving station can be monitored, the master control unit can send instructions to the wireless signal transmitting-receiving stations and the instructions are transmitted to all the transport trolleys through the wireless signal transmitting-receiving stations. Through the region-dividing management and control mode, complex wire lines are omitted and the stability and the safety of the AMHS are improved.
Description
Technical field
The present invention relates to semi-conductor integrated circuit mass transport board technical field, relate in particular to a kind of automatic material transfer system.
Background technology
Along with the development of semiconductor technology, 300mm silicon chip has progressively replaced 200mm silicon chip becomes main flow, and the weight of the silicon box of every box-packed year silicon chip also becomes approximately 9 kilograms by original approximately 4 kilograms.Therefore, still, by the manual conveyance of manpower, not only can lower efficiency, also have the possibility of carrying personnel personal injury.Simultaneously, quartz conductor is manufactured more and more harsh for the degree of utilization of factory building and the requirement of production cycle, automatic material transfer system (Automated Material Handling Systems is called for short AMHS) carries the importance of the tie of silicon chip also day by day to highlight as connecting between each manufacturing module.
Existing AMHS system all adopts the OHT waggon travelling on many track structures hanging on top ceiling and track, travel to and fro between (tool to tool transport model) between each board, or travel to and fro between between board and working area Stocker (between aisle in system interbay and aisle system intrabay).Between employing aisle as shown in Figure 1, the delivery system in aisle, each board 10 on every one side, board aisle is provided with silicon box stack portion 20(load port), OHT waggon 70(overhead hoist transport) can pick up the silicon box 30 in stack portion 20, and by track structure 60, be sent in the stack portion 20 of another board 10.The course of conveying of this silicon box 30 in same aisle is called system 110 in aisle, and the course of conveying of silicon box 30 between different aisle is called system 100 between aisle.In aisle, OHT waggon 70 is used in the conveying of system 110, between aisle, the conveying of system 100 is first silicon box 30 to be moved in working area 50 and temporarily stored with waggon 70, while by the time needing to use this silicon box 30, then with waggon 70 conveyances, arrive and specify board 10 places equally.
Generally speaking, in an AMHS system, have many waggons to move and execute the task simultaneously, all waggons are all to connect by overhead control cell signal, command the running route of waggon.If AMHS system scale is very large, need very huge control system, the signal connection of arranging to realize between each waggon and overhead control unit by Wireline quite takes time and effort, once and somewhere circuit breaks down in operation, by uncontrollable these waggons, bring hidden danger to stability and the safety of whole system.
Summary of the invention
The object of the invention is to make up above-mentioned the deficiencies in the prior art, a kind of automatic material transfer system is provided.
For achieving the above object, the invention provides a kind of automatic material transfer system, it comprises the board of rectangular laying, the track structure that many long rails and cross track suspention arrange, be located at least one the waggon travelling on track structure, overhead control unit, wherein, this waggon is provided with wireless signal transmitter and wireless signal receiver, this automatic material transfer system is also laid with a plurality of wireless signal transmitting-receiving stations, this wireless signal transmitting-receiving station is connected with the waggon signal in its signal range, this wireless signal transmitting-receiving station is also connected with overhead control cell signal.
Further, the signal range summation of all these wireless signal transmitting-receiving stations covers this track structure.
Further, this wireless signal transmitting-receiving station is connected by wired or wireless signal with overhead control unit.
Further, this waggon has control unit, and is connected with the wireless signal receiver signal of this waggon.
Automatic material transfer system of the present invention, by the setting of a plurality of wireless signal transmitting-receiving stations, can monitor all waggons in each wireless signal transmitting-receiving station signal range, overhead control unit can be sent to instruction wireless signal transmitting-receiving station, by wireless signal transmitting-receiving station, transfers to each waggon.The subregional management and control mode of the present invention has been saved numerous and diverse Wireline, has also improved stability and the safety of AMHS system.
Accompanying drawing explanation
For can clearer understanding objects, features and advantages of the present invention, below with reference to accompanying drawing, preferred embodiment of the present invention is described in detail, wherein:
Fig. 1 is the structural representation of existing automatic material transfer system;
Fig. 2 is the AMHS system schematic of first embodiment of the invention.
The specific embodiment
the first embodiment
Refer to Fig. 2, automatic material transfer system in the present embodiment, it comprises track structure that the board 11 of rectangular laying, many long rails 21 and cross track 22 suspentions arrange, is located at least one waggon 31, overhead control unit (not shown) of on track structure, travelling.
Wherein, waggon 31 is provided with wireless signal transmitter, wireless signal receiver and control unit (not shown), and control unit is connected with wireless signal receiver signal.Automatic material transfer system is also laid with four wireless signal transmitting-receiving stations, i.e. the first substation 41, the second substation 42, the 3rd substation 43 and the 4th substation 44, the signal range difference of four wireless signal transmitting-receiving stations first signal scope A, secondary signal scope B, the 3rd signal range C and the 4th signal range D as shown in Figure 2, and be connected with the waggon signal in its signal range respectively, four wireless signal transmitting-receiving stations are also connected by cable network signal with overhead control cell signal.As can be seen, the signal range summation of four wireless signal transmitting-receiving stations has covered whole track structure.
In the present embodiment, the Main Function of wireless signal transmitting-receiving station comprises two: the first, and forward the instruction of overhead control unit, and send to each waggon in each signal range, then drive it to travel by the control unit of each waggon; The second, receive the signal that in each signal range, waggon sends, monitor its orientation, have or not the information such as silicon box loading, and send to overhead control unit.
