1. Integral casting

The integrally cast frame is characterized by strong integrity and good rigidity. After the entire frame is cast, the aging treatment is adopted. The deformation of the frame is small and it is stable during work. High-end blister machines mostly use this kind of structure.

2. Steel plate welding type 

This type of frame is made of steel plates of various specifications, and then subjected to aging treatment to reduce stress and deformation. Its integrity is a little lower than that of integral casting, but it has the characteristics of simple processing and lower cost. In terms of appearance ( (Remove the machine shell) Welds can be seen. 

The structure of the blister machine depends on the overall design and load-bearing of the machine. Generally, the machine should be stable, relaxed, and vibration-free during operation (the metal coin will not fall over when standing on the machine). In a sense, the rack plays a key role. 

3. Conveyor and support table

The function of the transfer mechanism is to send the PCB that needs to be patched to a predetermined location, and then send the SMA to the next process after the patch is completed.

The conveying mechanism is an ultra-thin belt conveying system placed on the track. Usually the belt is placed on the edge of the track. The belt is divided into three sections: A, B, and C. There is a PCB clamping mechanism in the transfer area of the B area, and infrared sensors are installed in the A and C areas. More advanced blister machines also have Bar code reader, which can identify the incoming and outgoing PCBs, and record the number of PCBs.
