Abstract
The present invention relates to a vacuum suction pad applied to a vacuum transfer system. The vacuum suction pad has a structure in which a plurality of suction cells are formed by flexible partition walls. The vacuum suction pad includes a coil spring that is coaxially installed at a central portion in a longitudinal direction in each of the suction cells and spaced a distance from the partition wall and a pipeline flow control valve coupled to a lower end of the spring. The suction pad is coupled with a separately provided body to constitute a vacuum gripper of the present invention, and the gripper is connected to a vacuum pump through an exhaust port defined at one side of the body.
Claims8
A vacuum suction pad in which a plurality of suction cells (21) are consecutively disposed with a flexible partition wall (22) therebetween, the vacuum suction pad comprising:
- a flexible pad part (20) in which a lower end (22a) of the partition wall (22) at an opened side of the suction cell (21) is in contact with a surface of a product;
- a coil spring (30) that is coaxially installed at a central portion in a longitudinal direction in each of the cells (21) and spaced a distance (d1) from the partition wall (22);
- and
- a pipeline flow control valve (40) coupled to a lower end of the spring (30) and disposed in the suction cell (21) with an air passage (d2) defined between the partition wall (22) and the control valve (40), wherein a lower portion of a pipeline (41) corresponds to a surface of a product,
- wherein an inner space of each of the cells communicates with the outside through an exhaust hole disposed above the inner space.
A vacuum gripper comprising:
- a suction pad (10) in which a plurality of suction cells (21) are consecutively disposed with a flexible partition wall (22) therebetween, the vacuum suction pad comprising a flexible pad part (20) in which a lower end (22a) of the partition wall (22) at an opened side of the suction cell (21) is in contact with a surface of a product, a coil spring (30) that is coaxially installed at a central portion in a longitudinal direction in each of the cells (21) and spaced a distance (d1) from the partition wall (22), and a pipeline flow control valve (40) coupled to a lower end of the spring (30) and disposed in the suction cell (21) with an air passage (d2) defined between the partition wall (22) and the control valve (40), wherein a lower portion of a pipeline (41) corresponds to a surface of a product, wherein an inner space of each of the cells communicates with the outside through an exhaust hole disposed above the inner space;
- and
- a body (60) coupled to an upper side of the suction pad (10), wherein the body (60) comprises an inner vacuum chamber (61) configured to communicate with each of the suction cells (21) and the exhaust hole (23);
- and an exhaust port (62) configured to communicate with the chamber (61).
