Pick and place machine's placement program setting is the environment setting of the placement program, such as the configuration machine of the mounter and the coordinate reference origin, the selection of the component database and the selection of the feeder database, etc.
1. The configuration of the machine is the basic setting environment of the placement program. The configuration of the placement machine includes: the type of placement head; the location, type and accuracy of the camera; the parameters of the board transmission; the type and number of nozzles stored in the machine; the parameters of the automatic feeder; the parameters of the machine coordinate axis; other parameters.
2. Coordinate reference origin is the gap between the board coordinate origin and the chip component origin. Different equipment coordinate system direction is different. When the board's coordinate origin is located at the corner of the board, the coordinates of the SMD components based on the corner or reference point in the same direction as the origin of the puzzle board.
3. Component database: some machines can be based on different product lines to create and store multiple component database, and when needed to call a different database.
4. Feeder database is like a component database, it can also store multiple feeder database, you can choose according to the need.
5. The circuit board specification of the bonder is the size of the circuit board and the way of splicing the board.
The programming of smt placement machine needs to adjust the size of the circuit board according to the width of the circuit board conveyor track and the transmission distance, as well as the support device of the circuit board The support height can also be adjusted according to the thickness of the circuit board. General products of the circuit board using a single product; some products because of a single circuit board size is too small, not conducive to the production of placement equipment, or in order to improve the production efficiency of the equipment, reduce the transmission time of the circuit board, the use of multiple products. Board path. For multiple product panels, enter the component placement list, you only need to enter a panel components, the other panels can automatically copy the location of the components.
6. Board offset correction
Circuit board offset correction refers to the use of the board's reference point J to correct the patch coordinates. Reference points are some characteristic points on the circuit board, generally using the same printed circuit. The same process as the metal pad of the component is carried out simultaneously with the production of the circuit board. It can provide a fixed and accurate position and is a feature point for the overall correction of the component placement position. The calibration method of reference points on the circuit board can be divided into three types: the use of integrated calibration of reference points for all components on the board; the use of reference points on the puzzle board to correct the puzzle and its offset board component calibration; the use of reference points next to components to correct local single high-precision components.
