Abstract
The utility model discloses a transmission structure used for an AMHS delivery wagon, which comprises four transmission wheels fixed on the delivery wagon body, transmission belts on the transmission wheels, and grabbing modules connected to the lower parts of the four transmission belts, wherein the four transmission belts include three bearing belts and one line belt; the line belt is hollow and allows a line to penetrate through; the line is connected with the delivery wagon body and the grabbing modules respectively. According to the utility model, separation between a bearing unit and a line unit is realized; even if the bearing belts deform after being lifted repeatedly, the line in the line belt cannot be influenced, so that the security and stability of the delivery wagon and an AMHS system are improved, and the service life of the transmission structure is prolonged.
Description
Technical field
The utility model relates to semi-conductor integrated circuit material-transporting system technical field, relates in particular to a kind of drive mechanism for AMHS waggon.
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.In order to increase transmission efficiency, reduce and carry error rate, an automatic material transfer system (Automated Material Handling Systems is called for short AMHS) powerful and stable performance has been played the part of a very important role in 300mm factory.AMHS system not only can actv. be utilized the production space of valuable clean room, and can improve the degree of utilization of production facilities, shortening is in the production of articles time, so in the semiconductor factory of a lot of 300mm, AMHS is regarded as can fast lifting production capacity, increases point's sharp weapon of production efficiency.
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).
Waggon is as a part for AMHS system, can only low speed traveling single-line railway the more than ten years from the first generation, can only transplant and load the silicon box be positioned under it, to the second generation can high speed traveling at difference track, the third generation not only can traveling at difference track, can also left and right transfer be arranged on the silicon box on STS, UTS, then to the 4th generation 450mm floor truck, renewal speed is very fast.General waggon adopts the corresponding handling module of drive belt vertical lift to capture the silicon box on board for capturing silicon box conventionally.General waggon is apart from ground more than 3 meters, because it is highly higher, again as far as possible fast and pulsation-free transport and capture the silicon box of 9 kilograms of weighing, so the stability of waggon transmission module is very important.
The four piece drive belts of the handling module of waggon in transmission module are responsible for controlling lifting, the signal transmission line of controlling handling module is all installed in four belts, because the silicon box weight of 300mm is many compared with the silicon box increase of 200mm, the heavy burden of belt increases, belt repeatedly can produce distortion after lifting unavoidably, and the circuit of installation is wherein caused damage; In addition,, if certain line failure also cannot learn it is which the root damage in four belts, make troubles to processing and the solution of fault.
Utility model content
The purpose of this utility model is to make up above-mentioned the deficiencies in the prior art, a kind of drive mechanism for AMHS waggon is provided, by bearing unit and line unit, be separated, solve because belt distortion in drive mechanism causes the damage of internal wiring, be also convenient to process and solve fault.
For achieving the above object, the utility model provides a kind of drive mechanism for AMHS waggon, it comprises and is fixed on four power wheels, the drive belt on each power wheel of waggon car body and the handling module being connected with four drive belts belows, wherein, these four drive belts comprise three load-bearing belts and single line road belt, this circuit belt inner hollow is to run through circuit, and this circuit is connected with waggon car body and handling module respectively.
Further, these three load-bearing belts are solid.
Further, these three load-bearing belts arranges as a non-straight line.
Further, these three load-bearing belts arranges as equilateral triangle.
Further, this circuit comprises signal transmission line and supply line.
The drive mechanism for AMHS waggon that the utility model provides, circuit in four drive belts of script is integrated in a drive belt, form circuit belt, in its excess-three root, circuit is not set, forms load-bearing belt, realize the separated of bearing unit and line unit, even if load-bearing belt is in repeatedly distortion afterwards of lifting, can not affect the circuit in circuit belt, improve the safety and stability of waggon and AMHS system, extend the service life of drive mechanism yet; Secondly, utilize 3 principles that become face, the setting of three load-bearing belts can meet the requirement that handling module is adjusted levelness; Moreover, owing to only having a belt built-in signal transmission route and supply line, when line failure, can directly to this circuit belt, overhaul, reduced the time of processing and solving fault, improved the work efficiency of AMHS system.
Accompanying drawing explanation
For clearlyer understanding the purpose of this utility model, feature and advantage, below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail, wherein:
Fig. 1 is the structural representation of the utility model the first embodiment waggon.
The specific embodiment
Refer to Fig. 1, the drive mechanism for AMHS waggon of the present embodiment, a part as OHT waggon in suspension type AMHS system, comprise four power wheels 12, the drive belt 13 on each power wheel and this four handling modules 14 that drive belt 13 lower ends connect of being fixed on waggon car body 11, handling module 14 lower ends have handgrip, for picking and placeing silicon box 2 from equipment such as board, temporary storage equipments (Stocker).
Wherein, four drive belts 13 comprise three load-bearing belts 131 and single line road belt 132, and circuit belt 132 inner hollow are used for running through required circuit, and this circuit is connected with waggon car body 11 and handling module 14 respectively.The circuit of the present embodiment comprises signal transmission line and supply line, the command that signal transmission line can send control unit in waggon car body etc. is to handling module, control it and pick and place silicon box, supply line is for providing required power supply to handling module.
In the present embodiment, load-bearing belt is solid, can improve its load-carrying capacity like this, and circuit belt does not play carrying effect, only for circuit, cable provide, runs through place.Therefore, circuit belt can be slightly longer than load-bearing belt, with after the anamorphic stretching of load-bearing belt, is unlikely to the circuit in damaged line belt.Meanwhile, three load-bearing belts utilize 3 the principle of one side, still can adjust to handling module the operation of levelness.Preferably, three load-bearing belts arranging in longitudinal projection is a non-straight line, and three power wheels under load-bearing belt are a non-straight line in waggon car body; More preferably, be equilateral triangle, its stressed and leveling best results.
The present embodiment, owing to only having single line road belt built-in signal transmission route and supply line, when line failure, can directly overhaul this circuit belt, has reduced the time of processing and solving fault, has improved the work efficiency of AMHS system.
