The utility model discloses a CNC vacuum chuck clamping machine constructs includes sucking disc 1, rubber ring 2, vacuum generator 3.

As shown in fig. 1, 6 counter bores 11 are distributed at the edge of the suction cup 1 for fixing the suction cup. One or more module placement areas 12 may be distributed on the suction plate 1. Taking one of the module placement areas 12 as an example, the module placement area 12 is planar below the suction cup surface and slightly larger than the module size so that the module can be embedded in that area. The edge of the area is provided with an annular sealing groove 121, and the rubber ring 2 is partially embedded in the annular sealing groove 121. The module placing area 12 is provided with a vacuum groove 122 shaped like Chinese character 'yu', and copper pillar supporting points 123 are arranged in the positions, corresponding to the copper pillars on the back surface of the module, in the four-side grooves of the vacuum groove 122; the vacuum grooves 122 have a plurality of vacuum suction ports 124 at the bottom of the middle straight groove, and the vacuum suction ports 124 are communicated with an external air source through an air flow channel inside the suction cup and the vacuum generator 3 fixed at the edge of the suction cup.

The rubber ring 2 is a silica gel ring, and the thickness of the silica gel ring is 2mm; the annular seal groove 121 has a depth of 1.5mm and a width of 2mm.

Before processing the copper column, fixing a sucker on a machine table of CNC equipment through a screw at a counter bore 11, and then placing the front face of a module in a module placing area 12 in an oriented mode; at the moment, the edge part of the module 4 is pressed on the rubber ring 2, a certain gap is formed between the front surface of the module and the surface of the module placing area 12, and the position of the copper column 41 corresponds to the position of the copper column supporting point 123; the positive pressure of the air source is changed to negative pressure, the vacuum generator 3 is turned on, and the module 4 is sucked to the suction cup through the vacuum groove 122 and the vacuum suction port 124. The rubber ring is stressed and compressed in the adsorption process, if the rubber ring is too high, the deformation amount is large, the module cannot be completely attached to a certain position, otherwise, if the rubber ring is too short, the deformation amount is too small or no deformation amount exists, a closed space cannot be formed between the front face of the module and the module placement area 12, and the module cannot be adsorbed. The utility model discloses well rubber ring 2 highly slightly is greater than the degree of depth of annular vacuum groove 122, and the rubber ring deformation volume is moderate during the evacuation, can make the module openly place regional 12 with the module and laminate completely and adsorb firmly, thereby guarantees adding man-hour the module can not produce the machining precision that the momentum influences the copper post.
