Discribtion:

Pressure Foot Cup is the irreplaceable part on PCB molding machine. It is placed on pneumatic rod to link with brush
parts for cleaning the PCBA that prevents PCBA from been corroded and oxdized. This new type pressure foot is
ued on the drilling routing machine.

Pressure foot assembly:

In the past when drilling holes with a diameter of 0.5mm or more, under the condition that the CPK (Process Capability Index) ≥ 1.33 on the reverse side of the floor and the hole wall roughness ≤ 25.4μm were used, a fixed chip suction cover and a single-hole pressure foot were usually used. As the drilling hole diameter of printed circuit boards is gradually reduced (currently mainly concentrated at φ0.3mm, most of φ0.1 ~ 0.2mm), the precision of the pressure foot assembly of traditional chip suction hood and single-hole pressure foot configuration in the drilling accuracy And drilling quality are somewhat inadequate, which affects machining accuracy. To this end, a switching foot assembly is designed. The inner diameter of φ8.5mm is responsible for drilling large holes, and the inner diameter of φ2.5mm is responsible for drilling small holes.

Form and material of pressure foot:

The main function of the pressure foot is to compact the workpiece system. Through its slotted ventilation structure, it provides air supplement for the vacuum system, forms a better convection system, and has a larger buffer effect. Different brands of mechanical drilling design manufacturers based on different considerations, the material of the pressure foot is metal materials and non-metal materials. Metal materials are mainly stainless steel (usually SUS304) and brass materials (C3604BD, equivalent to HPb59-1). Non-metal materials are mainly PA66, PA6, POM and PU. The main considerations for the use of metal materials are relatively high hardness, wear resistance, and long service life (normally 8-10 months can be used); the disadvantage is that the buffer effect is not obvious, and it has not stabilized for a long time. The use of industrial rubber materials (PU, PA6 PA66) mainly considers good vibration absorption characteristics. For the impact process, it can achieve a significant vibration absorption effect, and the amplitude can be reduced in a short time. The disadvantage is that the hardness is relatively low and it is not resistant to wear. Life is short, usually around a week. Using ABAQUS software simulation, adjust the presser foot material, analyze with 100N presser foot force and 10kpa vacuum void, and analyze the use of rigid presser foot and PU presser foot. As shown in Figure 5, the upper and lower curves respectively indicate the numerical displacement curve of the "drill point" under the steel presser foot and the PU presser foot.
