The advantage of multi-function placement machine is also called medium-speed placement machine or general-purpose machine. Siemens e-by series and Fuji xpf series all belong to medium-speed placement machine, that is, multi-function placement machine. This type of machine can paste large materials or small materials, which is very suitable for small batch and multi-variety mounting requirements.

Multifunctional placement machines are also called general placement machines in some SMT manufacturing companies, which are a kind of arch type placement machines. Multifunctional placement machine because of the placement
Generally, the components are relatively large in size and require precision placement. Therefore, the number of components placed when the multi-function placement machine is generally used in conjunction with the high-speed placement machine
For less and more, it can be used with high-speed placement machine to achieve a balance of production efficiency. The features of the multifunctional placement machine are as follows:

Multifunctional placement machine

1. The structure of the multi-function placement machine mostly adopts the arch structure, which has the characteristics of high precision and good flexibility.

2. Most of the X and Y positioning systems are driven by full-closed-loop servo motors, and linear grating encoders are used for direct position feedback to avoid
Error of twisting and deformation of screw rod. Some use dual motors and dual screw rods on the y-axis to drive on both sides of the platform, and use dual linear gratings for feedback.
It can effectively reduce the waiting caused by the static placement of the head, and reduce the error caused by the asynchronous deformation of the beam. There are more advanced linear magnetic
In addition to the technical characteristics of each dual drive, the suspension motor also has direct drive, less wear on the mechanical structure, fast feedback, quiet, easy maintenance and precise
High degree of characteristics.

3. The multi-kinetic energy placement machine mostly adopts the fixed circuit board, and uses the movement of the placement head to realize the X and y positioning.
Or heavier components are displaced due to inertia.

4. It can accept all material packaging methods, such as tape, tube, box and tray. In addition, when there are a lot of materials on the plate, multi-layer special
Use tray feeder.

5. In addition to traditional vacuum suction nozzles, special suction nozzles can be used for special-shaped components that are difficult to suction. In addition,
Pneumatic grippers can be used for components sucked by the vacuum suction nozzle method.

6. When the components are calibrated, a top-view camera is generally used, which has the functions of front light, side light, backlight and online light, which can identify various components. Such as
If the size of the component is too large and exceeds the FOV of the camera, the top-view camera can also perform comprehensive analysis and correction after taking multiple videos.
. The placement head of some multifunctional placement machines is also equipped with a placement head moving camera, which can identify various smaller components.

7. In some products, some perforated plug-in (Pin h Paste) components also need to be mounted at the same time as other SMD components and processed by reflow soldering.
, The insertion of this perforated plug-in component requires the machine to have the ability to mount under high pressure. The placement heads of some multifunctional placement machines have high-pressure placement
Ability, placement pressure can be controlled by the program, up to 5 kg.

8. Some multi-function placement machines can be equipped with a flux dipping assembly system (Flux Dipping Assembly), which can be used for component stacking and packaging
(Package on Package) and Flip Chip (Flip Chip) placement.
