Vi) transmit object in the position of verification object, and each object is transported to relieving platform from each; And if necessary; Also

Vii) original or updated information bag each is sent to any other system, and this system needs this packets of information because of other operation.

In another preferred embodiment, this distribution system should be able to be labelled to object, makes in the entire process process and can follow the tracks of object fully.

According to another aspect of the present invention, in the distribution system that provides, this distribution system is integrated in the system ensemble together with at least one AOI system and a plurality of checking table, buffer table, and relieving platform.

Description of drawings

Below only with way of example, with reference to description of drawings the present invention.Now, the special figure of reference is in detail pointed out emphatically, the figure that specifically draws only with way of example and only for the purpose of the explanation preferred embodiment of the present invention, and provides the explanation of thinking the most useful content and understanding the principle of the invention and notion easily.Thus, except that essential to basic comprehension of the present invention, do not attempt the more detailed CONSTRUCTED SPECIFICATION of the present invention that shows, in conjunction with the explanation that figure is done, effect is the guiding one skilled in the art, and how reality is implemented to understand some kinds of forms of the present invention.

Among the figure:

Fig. 1 block scheme of one embodiment of the invention that draws.

Embodiment

The present invention be a kind of object from automatic visual inspection (AOI) system assignment to a plurality of checking tables, afterwards again to each other distribution system.

In a preferred embodiment of the invention, the configuration that comprises AOI system, a plurality of checking table, mechanical arm and controller is arranged.

Controller receives the position of scanned object and about the packets of information of this object from the AOI system.Packets of information can comprise the picture of object and/or the picture of suspicious defective, the information of identification, or the like.The availability of relevant each checking table is also upgraded continuously in the controller.

The control order mechanical arm transmits scanned object from the position that receives, and then object is transported to one of available checking table, so that the suspicious defective of verification.Realize verification, controller together with object, is sent to this available checking table to packets of information, thereby can realize automatic coordinate configuration.If desired, controller can be sent to any the other system that needs this information to original or updated information.

Batch operation in this configuration is also finished automatically expeditiously.Under whole all disabled situations of platform, the control order mechanical arm is transported to object and waits on the platform, waits for that being about to first becomes available checking table.

Object is in case verification finishes, and controller is sent to relieving platform to object.

With reference to figure and appended explanation, can understand principle and operation better according to distribution system of the present invention.

With reference now to accompanying drawing,, Fig. 1 block scheme of one embodiment of the invention that draws.AOI system 11 is configurations that a plurality of checking tables 12 are arranged.Scanned object 13 waits for that in the output of AOI system 11 AOI system 11 is sent to controller 14 to the position of each object and packets of information.Controller 14 in turn upgrades the availability of relevant each checking table 12.

Controller 14 order mechanical arms 15 are implemented move operation 17, move on on the specific object 16, so that pick up object 16.One of controller 14 identification checking tables 18 are available, and order mechanical arm 15 enforcement move operations 19, so that an object 16 of picking up is transported to available checking table 18.Simultaneously, controller 14 is the packets of information about the object 16 picked up, is sent to will be the checking table that the object of picking up 16 is transported to identical checking table 18.

Under all disabled situation of complete verification platform 12, controller 14 order mechanical arms 15 are transported to buffer table 20 to the objects of picking up 16 and wait for, become availablely until one of checking table 12, and mechanical arm 15 is carried this object on this available platform then.

Though in conjunction with specific embodiments of the invention, the present invention has been described, but it is needless to say more, manyly substitute, revise and change, to the one skilled in the art is conspicuous, therefore, will be understood that the present invention is contained spirit and all these classes in the broad range of investing back claims and substituted, revises and change.
