Abstract
The invention provides a dispenser positioning method. A stand is used for driving a dispenser to move in the X axle direction, the Y axle direction and the Z axle direction corresponding to a zero-in tool to perform a Z axle correction step, an X axle correction step and a Y axle correction step so as to define a coordinate, serving as a virtual origin, according to measured X axle virtual origin, Y axle virtual origin and Z axle virtual origin, and uses the virtual origin as reference to set various dispensing positions of a dispensing needle head of the dispenser in the dispensing operation so as to achieve the purpose of dispensing glue in proper positions. As the dispenser positioning method uses the zero-in tool and zero-in signals to set the virtual origin of the dispenser, the whole equipment is simple in mechanism and low in production cost.
Description
Technical field
The present invention relates to a kind of point gum machine localization method of dispensing needle head position of recoverable point gum machine.
Background technology
Various electronic wafer, optical lens, touch panel ... time mostly need to utilize point gum machine to give me a little coating viscosity glue Deng electronic installation in assembling, so that the electronic component in this electronic installation can mutually combine is fixing.And along with the progress of science and technology, the size of various electronic component is more and more less, accordingly, the some glue position of this point gum machine must be very accurate, otherwise cannot be viscose glue spot printing in position.
The method that viscose glue point can be coated in to tram of prior art, as shown in No. I367787 " thering is dispensing method and the point gum machine of error correcting function " patent of invention case of TaiWan, China letters patent book number, on the whole it is first utilize a taking unit to obtain a tool and be located at the image of overlooking for the treatment of a glue part on this tool, recycle an identification software and overlook according to this that image records the pivot of this tool and this treats the error distance at Dian Jiaojian center, and put glue position after point gum machine being moved to a correction according to this error distance, to correctly carry out a glue.
But, except this tool and treat that a relative position for glue part can produce error and must carry out error correction, after changing dispensing needle head set on point gum machine at every turn, also will certainly there be error the position of this dispensing needle head, if do not proofread and correct in time the position of this dispensing needle head, by cause equally cannot be by viscose glue spot printing problem in position.
Moreover, because the dispensing method of above-mentioned prior art is utilize taking unit to obtain tool and treat that a mode of the image of glue part proofreaies and correct the some glue position of point gum machine, to adopt CCD (Charge-Coupled Device and be somebody's turn to do " taking unit ", charge coupled cell) video camera, but it is also relatively high for the price of the CCD camera of correct error in measurement distance to have high-res, so that this point gum machine with error correcting function also has the problem that cost is high.
Summary of the invention
In order to solve the existing problem of aforementioned prior art, the object of the present invention is to provide a kind of point gum machine localization method, the position of the dispensing needle head of its recoverable point gum machine, and mechanism is simple, cost is low.
The present invention is that the technical scheme that solves its technical problem employing is: this point gum machine localization method utilizes a zero-in tool to set the virtual origin of a dispensing needle head set on a point gum machine, one board can drive this point gum machine along X-direction, Y direction and Z-direction move, this zero-in tool is a cuboid and has an end face, one first side and one second side, the Z axis moving direction of vertical this board of this end face, the X-axis moving direction of this this board of the first lateral vertical, the Y-axis moving direction of this this board of the second lateral vertical, wherein, point gum machine localization method of the present invention comprises:
One Z axis aligning step, wherein, first make board drive this point gum machine, the dispensing needle head of this point gum machine is moved to end face that should zero-in tool, then make this board drive this point gum machine to move towards the direction that approaches this zero-in tool along Z axis, in the time that dispensing needle head touches the end face of this zero-in tool, this dispensing needle head can form current conductive state and trigger a zero-in signal, then after this board first drives point gum machine oppositely to move along Z axis towards the direction away from this zero-in tool, drive again point gum machine to move towards the direction that approaches this zero-in tool along Z axis, until again touch the end face of this zero-in tool, and again trigger this zero-in signal, now, the absolute position of the end face that records this zero-in tool in Z-direction is Z axis virtual origin,
