   Smt placement machine online programming refers to the use of the teaching attached to some machines for program editing and the use of the placement program editing function in the application software of the placement machine. Online programming methods include teaching programming and manual input programming. In addition, the component placement coordinates on the circuit board and the component database can also be taught and corrected on the machine.

   One, Smt placement machine teaching programming

The traditional Smt placement machine programming method uses the placement machine's manual teaching method, using the teaching box, that is, moving the camera to find the coordinate positions of all the placement components on the circuit board, and then the other information of the components such as the position of the components Information such as number, code and placement angle are manually input into the Smt placement machine. Teaching programming is the simplest basic programming method, which is generally used in old-fashioned medium-speed machines. This method takes up the production time of the machine, and the manual teaching method to find a point is a time-consuming, laborious and error-prone work for a circuit board with hundreds of SMD components.

①Reclaiming and teaching: select the nozzle type, use the teaching box to move the placement head to the top of the feeder, drop and pick up the components, and determine the centering method, the control computer of the Smt placement machine will automatically record The XYzQ coordinates of reclaiming and other reclaiming correction methods.

②SMD teaching: After taking material teaching, picking components, correction and angle rotation are completed, use the teaching box to move the placement head to the top of the component welding pattern on the circuit board, and the circuit board recognition camera can be used to determine the center of the component. Then drop the component onto the circuit board and click input.

  ③Complete the circuit board transmission, feeder and nozzle setting and position teaching: after reclaiming teaching and placement teaching, placement sequence programming and teaching can be carried out. Placement sequence programming can be carried out through the teaching box, and can also be automatically optimized using the automatic programming function attached to the placement machine software.

   2. Placement machine manual input programming

  All placement machines can be programmed by manual input. In the placement list of the programming software, after entering the RefID of the component, select the component database code of the component, and enter the x, y coordinates and rotation angle of the component. This is the most important thing about the placement machine program. information. Then enter the station numbers of various component codes and optimize the placement sequence to complete the placement machine programming.

   Three, placement coordinate teaching correction

Because sometimes the accurate coordinates of SMT component placement cannot be obtained, it will be very troublesome to change the coordinates after the first circuit board is placed. Therefore, some placement machines also provide the correction function of component coordinates, which is also called enhanced program. Settings (Enhanced Product Setup). The enhanced program setting uses the machine's PEC camera to intuitively display the graphics of the placement position, which can effectively improve the accuracy of programming.

   What if we need to edit the Smt placement machine again?

  The first step: First, reprogram the system: The placement machine system generally uses two programming methods: manual programming and computer programming. Many low-level placement machines usually use manual teaching programming, and fully active placement machines such as Huaweiguo Chuang placement machine can completely use computer automation for programming.

Step 2: Replace the original production feeder: to reduce the time for the placement machine to replace the feeder, the more common method is to use the "quick release" feeder, and the faster method is to replace the feeder structure to make the placement machine The feeder of each component on the substrate type is installed on a separate feeder rack for replacement.

  The third step: the adjustment of the transmission organization and positioning table: When the size of the replacement substrate board is not the same as the size of the current device, the width of the substrate board positioning table and the transportation organization of the substrate board should be adjusted. The fully active placement machine can be adjusted actively under program control, and the next-level placement machine can be adjusted manually.

   Step 4: Replace the placement head: When the type of component to be installed on the SMT substrate exceeds the size of the placement head, perhaps when the substrate type is changed, the placement head of the placement machine is often replaced or adjusted. Most fully active placement machines can actively perform replacement and adjustment of the placement head under program control, while some small-brand placement machines need to perform such operations manually.
