Description

Round diaphragm extractor

The present invention is a suction device, especially an extraction head having a negative pressure at the end of its suction member for sucking a circular diaphragm.

The prior art is used for extracting a circular diaphragm, which is disposed on a circular diaphragm device. The specific embodiment is generally mounted on a transfer mechanism of the production device, and the displacement is made by the displacement of the transfer mechanism. The head moves between the workstations, that is, a circular diaphragm is adsorbed by a picking head at a workstation, and is separated after being moved to another workstation.

As shown in FIG. 9, the structure of the extraction head 50 is generally provided with a shaft hole 500 in the body of the extraction head, and at least one passage 51 is formed in the interior thereof. The passage 51 has an exhaust port formed at the top end of the body. The bottom end is formed with an air inlet 52 which is connected to the vacuum generator so that the passage 51 and the air inlet 52 are formed in a negative pressure state, whereby a suction force is formed at the air inlet 52 of the bottom end of the body. Referring to FIG. 10, the extraction head 50 is mounted on a robot arm 80. The robot arm 80 is provided with a carrier 81. The carrier 81 has a shaft 82 and a shaft hole 500 of the extraction head 50. An elastic member 83 is disposed between the opposite outer sides of the extraction head 50 and the carrier 81 so that the extraction head 50 can be oscillated and reset.

Referring again to FIG. 11, when the carrier 60 is loaded with the circular diaphragm 70, the extraction head 50 is moved to the carrier 60 via the transfer mechanism, and the extraction head 50 is moved toward the carrier 60, and the head 50 is to be extracted. When the bottom end portion is close to the circular diaphragm 70, the circular diaphragm 70 is adsorbed by the suction force formed at the air inlet 52, and then moved to the next workstation, since the extraction head 50 is generally made of a hard material. For example, it is made of a metal material and is a hard component, and in order to prevent the adsorbed circular diaphragm 70 from being separated from the extraction head 50 during the transfer process, the vacuum suction provided has a certain strength. When the circular diaphragm 70 is subjected to suction to move toward the bottom end of the extraction head 50, the two will collide with each other to cause the circular diaphragm 70 to be extremely vulnerable to collision damage, which is a disadvantage of the prior art extraction head configuration. .

In order to solve the shortcomings of the prior art extraction head, the present invention is provided with a soft sheath at the bottom end of the extraction head, so that the adsorbed circular diaphragm is less damaged during production.

In order to achieve the foregoing creative purpose, the technical means used in the present invention is to provide a circular diaphragm extracting head, the extracting head comprising a body and a sheath; the body is a body and has at least one passage, each of the passages running through Each of the channels has an exhaust port and an air inlet at each end of the body; the sheath is a soft hollow body having a chamber and at least one suction port, and the cavity is formed in the cavity At the one end surface of the sheath, each of the suction ports communicates with the chamber through the sheath; the sheath is assembled at an end of the body provided with an air inlet, and the suction port communicates with the air inlet.

The circular diaphragm extracting head, wherein the body further has an assembly seat and a first joint portion, the assembly seat is at one end of the body, and the first joint portion is formed at the assembly seat, the air inlet The second jacketing portion is further disposed at a position of the second joint portion, the second joint portion is away from the suction port, and the jacket is a hollow sleeve body and the assembly seat are mutually nested, the first The joint portion and the second joint portion are connected and fixed to each other.
