Description
Technical field
The present invention relates to a kind of deviation correcting device, especially a kind of printing equipment deviation correcting device.
Background technology
At present, printing equipment has been widely used in surface mounting technology, along with printed circuit board is to the future development of microminiaturization, high density, zero-fault, has higher requirement to the precision of printing equipment.In the processing step of complexity, vision measurement and planar three freedom correction adjustment are the keys that printing equipment realizes fine registration, traditional three-freedom planar adjusting mechanism adopts typically " sandwich+series connection " this overlapped in series structure usually, be easy to control, but because underlying platform needs to support thick and heavy superstructure, and in order to avoid vibration under rapid-aligning, this cascaded structure volume and weight is relatively large, and terminal response is slower.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of printing equipment deviation correcting device, there is the simple and advantage that terminal response is fast of structure.
In order to achieve the above object, the invention provides a kind of printing equipment deviation correcting device, comprise vision measurement device and three-freedom planar in parallel to bit platform, described vision measurement device is made up of two degrees of freedom visual movement subsystem and image collecting device, described image collecting device is made up of camera, lighting device and image pick-up card, and described two degrees of freedom visual movement subsystem is driven by servomotor and precise ball screw.
Described three-freedom planar contraposition stage+module in parallel is in a rigid hoisting mechanisms, and the adjustment contraposition as screen printing apparatus is undertaken the printing of module, is made up of fixed platform, moving platform, three movement branched chain and four support rollers.
Described three movement branched chain respectively containing active moving sets, revolute pair and a passive moving sets, are wherein connected by a fixed length connecting rod between revolute pair with passive moving sets, the vertical moving sets direction of motion of connecting rod.
Two-dimensional visual motion subsystem is typical serial mechanism, and its positioning error can be divided into for kinematic parameter error and structural parameters error, and kinematic parameter error is screw rod transmission ratio error; Image collecting device as shown in Figure 2, the aligning of special caliberating device to camera is adopted tentatively to demarcate before the mounting, after installation, pixel equivalent value generally adopts photoetching high-precision optical glass to demarcate, vision measurement device obtains the round dot matrix image on optical glass scaling board by camera, then uses image matching algorithm, obtains the picture element position information of dot matrix, compared with the actual position information of scaling board, obtain the pixel equivalent average of vision measurement system thus.
The groundwork flow process of printing equipment deviation correcting device of the present invention is: according to process parameter, substrate is transported in parallel on bit platform by travelling belt, visual movement subsystem drives image collecting device to move to assigned address, take the dot image of substrate and template simultaneously, the positional information of substrate and template is obtained after image procossing, and with this calculate platform need from current pose (substrate) to object pose (substrate) needed for the anglec of rotation and displacement, then according to the Inverse Kinematics Solution model of parallel connection to bit platform, calculate the input quantity of three movement branched chain motors, then drive motor, realize contraposition.
The invention has the beneficial effects as follows: a kind of printing equipment deviation correcting device provided by the present invention, structure is simple, and terminal response is fast, improves the positioning precision to bit platform in parallel.
