US Patent 10456928 Vacuum gripper unit comprising vacuum pump

The present invention relates to a vacuum gripper unit. The unit has a first mounting container and a second mounting container of cylindrical shapes formed in an H-type when seen from the outside, including a main body for providing a common vacuum chamber. A vacuum pump is inserted into the first mounting container, while the vacuum pump or a release valve is selectively mounted in the second mounting container. In addition, a front insertion hole of each of the first mounting container and the second mounting container is provided with a finishing material which supports each of the release valve and the vacuum pump that are mounted to thereby prevent the valve and pump from being separated. It is preferable that the finishing material of at least the first mounting container is a silencer.
