Referring to Figure 1, the pickup apparatus 100 according to the present invention is a device for picking up the object (L) located on the holding member 10, the support member 110, the support pin 120, and the picker ( 130).

The object L may be, for example, a thin workpiece such as a semiconductor chip or an LED chip, but the object L is not necessarily limited to a semiconductor chip or an LED chip. These objects L are usually located on the sticky holding member 10, such as a blue tape, are often held, stored or supplied. However, the holding member 10 is not limited to the blue tape, for example, the surface facing the object has adhesiveness or adhesion, and any thin film having flexibility for separation from the object may be used as the holding member 10. Can be. In order to process, process, test, and classify the object L, the holding member 10 must be peeled off and picked up from the object L. Hereinafter, the components necessary for the pickup of the object L will be described in more detail. Let's do it.

In the pickup device 100 according to the present invention, the support member 110 is located below the holding member 10. The support member 110 may be formed of, for example, a cylindrical member, but the shape of the support member 110 is not limited to the cylindrical shape and may be formed in various shapes.

The upper surface of the support member 110 has a contact surface 113 is in direct contact with the lower surface of the holding member 10, the groove 111 is formed in the inner region of the contact surface 113 is recessed to a certain depth. This groove 111 is used as a space for removing the holding member 10 from the object (L). The groove 111 may be formed in a hemispherical shape, but is not limited thereto and may be formed in various shapes such as a cylindrical shape and a rectangular shape.

When the support member 110 is a cylindrical member and the groove 111 is formed in a hemispherical shape, the contact surface 113 is provided in a ring shape as shown in the plan view of FIG. 5, and the contact surface 113 in the ring shape is shown. The holding member 10 is in contact with the support. In this case, the object L on the holding member 10 is positioned above the region where the groove 111 is located.

An installation hole 114 for lifting and lowering of the support pin 120 may be provided at the center of the groove 111. The installation hole 114 is installed to penetrate the installation space and the groove 111 inside the support member 110 in which the support pin 120 is maintained, and the support pin 120 supports the center of the object L. It is formed in the center of the groove 111 to enable. The installation hole 114 has a size and shape that does not interfere with the lifting movement of the support pin 120. 1 and 5, the installation hole 114 may be a cylindrical shape hole, but the shape of the installation hole 114 is not limited to a cylindrical shape, various conditions such as the shape of the support pin 120 It may have an appropriate shape according to.

In addition, an intake hole 112 may be provided around the installation hole 114 in the groove 111 of the support member 110 for inflow and outflow of air. Like the installation hole 114, the intake hole 112 is installed to penetrate the installation space and the groove 111 inside the support member 110 in which the support pin 120 is held. A plurality of intake holes 112 may be provided, and in this case, the intake holes 112 may be installed at predetermined intervals, for example, at equal intervals in the circumferential direction with respect to the installation hole 114. When the intake holes 112 are installed at equal intervals, the air inside the groove 111 may flow in and out uniformly. The intake hole 112 inhales air inside the groove 111 to provide a suction force, so that the holding member 10 moves inside the groove 111, that is, in the direction indicated by the arrow A in FIG. 1. do.

As shown in FIG. 1, an intake apparatus 20 may be provided on one side of the support member 110. The intake apparatus 20 communicates with the intake hole 112 of the groove 111, thereby providing a suction force for moving the holding member 10 in the direction of arrow A. FIG. The intake apparatus 20 is connected to the support member 110 through a connection hole 115 formed on one side or the bottom surface of the support member 110 so as not to interfere with other components such as the holding member 10. As shown in FIG. 1, when the support pin 120 is spaced apart from the holding member 10, air may be sucked through not only the intake hole 112 but also the installation hole 114. 112 and the installation hole 114 is connected to the intake apparatus 20 through an installation space and a connection hole 115 inside the support member 110 in which the support pin 120 is held. As described above, when the intake apparatus 20 starts suction of the fluid, the holding member 10 may be moved in the direction in which the groove 111 is located, and when the intake apparatus 20 stops suction of the fluid, the holding member ( 10) can be moved to its original position.

The support pin 120 is installed on the support member 110 to support the object L by penetrating the holding member 10. Specifically, the support pin 120 is installed to protrude in the direction toward the holding member 10 from the inside of the groove 111. When the intake apparatus 20 sucks the fluid, the holding member 10 can be easily removed from the object L because the holding member 10 is penetrated by the support pin 120. The support pin 120 may be positioned below the holding member 10, may be positioned in the groove 111 through the supporting member 110, or may contact the bottom surface of the holding member 10.

The support pin 120 is a member having a rod or pin shape that is vertically long and may be formed to decrease in size in a direction toward the inside of the groove, that is, in the direction of an arrow A in FIG. 1. In addition, if the upper side of the support pin 120 to form a tip, not only the penetration of the holding member 10 is easy, but also the area of the support pin 120 in contact with the object (L) is reduced to damage the object (L) Will be reduced.

The support pin 120 may be elevated through the installation hole 114 of the support member 110. For example, the support pin 120 may be moved relative to the fixed support member 110 by a separate moving means coupled to the support pin 120. On the contrary, the support pin 120 is fixed to the support member 110. It is also possible to move only. In addition, both the support member 110 and the support pin 120 may be formed to be movable.

Picker 130 is a device that is installed on the upper side of the object (L) can pick up the object (L). The picker 130 may be, for example, a device for adsorbing the object L by the negative pressure of air or fixing the object L by the electrostatic force, and stably picking up the object L without damaging the object L as much as possible. As long as the device can be used, the mechanism and kind thereof are not particularly limited. In addition, the picker 130 is connected to a picker arm or a rotating arm, which is not shown, and the picker arm and the rotating arm are connected to a motor or the like, so that the object L picked up by the picker 130 is driven by a predetermined drive. Can be moved to the desired position.

Referring to FIG. 5, the distance d1 between the intake hole 112 and the center 114 of the support member 110 is greater than the distance d2 between the intake hole 110 and the contact surface 113 when viewed from the top. The intake hole 112 is provided to be short. When the intake hole 112 is formed at a position closer to the contact surface 113 than the center 114 of the support member 110, the inlet hole 112 is moved to the holding member 10 before the holding member 10 is completely removed from the object L. Due to the intake hole 112 is closed, the suction force may no longer be transmitted. In order to prevent this, the intake hole 112 is preferably formed at a position closer to the center 114 of the support member 110 than the contact surface 113.

Hereinafter, the operation of the pickup apparatus will be described with reference to FIGS. 1 to 4. Here, it is assumed that the support member 110 of the pickup device 100 is fixed, and the support pin 120 is connected to a pin lifting device (not shown) to be able to lift up and down.

The pin lifting device may be installed on the support member 110. In addition, the pin lifting device can directly raise and lower the support pin 120 using a hydraulic cylinder or a pneumatic cylinder, and the support pin using a motor and a coupling mechanism coupled to the motor and the support pin 120, respectively. It is also possible to raise and lower 120. The connection mechanism may include at least one of a pulley and a belt, a ball screw, a cam member, a rack pinion gear, and the like.

The support pin 120 has a rising position where the support pin 120 is in contact with the holding member 10 and a lowering position where the support pin 120 is positioned below the holding member 10 and does not contact the holding member 10. Move up and down between locations. That is, the pin lifting device may raise the support pin 120 such that the support pin 120 reaches the raised position as shown in FIG. 2. In addition, the pin lifting device may lower the support pin 120 so that the support pin 120 reaches the lowered position as shown in FIG.

As a first step in the pickup process, the pickup device 100 is initially set to the position as shown in FIG. That is, the object (L) is attached to the holding member 10, the support pin 120 is located in the lowered position not in contact with the holding member 10 from the lower side of the holding member 10, picker 130 ) Maintains a state in which the object L does not come into contact with the object L above.

As a second step of the pick-up process, the support pin 120 is raised to the rising position relative to the support member 110, and then the picker 130 is lowered in contact with the object (L) to pick up it.

When the support pin 120 reaches the raised position, as shown in FIG. 3, a part of the support pin 120 may be inserted into the holding member 10. In addition, when the support pin 120 reaches the raised position, as shown in FIG. 4, an upper end of the support pin 120 may penetrate the holding member 10 to contact the bottom surface of the object L. Referring to FIG.

Accordingly, when the support pin 120 reaches the raised position, the retaining member 10 may be partially or totally drilled, and then the retaining member 10 moves inside the groove 111. Therefore, the holding member 10 may be more easily removed from the object L picked up by the picker 130. In addition, since the object L is supported by the support pin 120 when the holding member 10 is moved into the groove 111, the picker 130 may stably pick up the object L.

On the other hand, the picker 130 is in danger of descending a distance greater than the distance that must be lowered to pick up the object (L). In addition, since the picker 130 descends at a high speed and stops, vibration may occur in the state in which the picker 130 is in contact with the object L. FIG. By the way, in the state in which the support pin 120 is located in the rising position, if the falling distance of the picker 130 is increased or vibration occurs as described above, the object L is supported by the support pin 120 in the rising position. There is a risk of damage.

Therefore, as an alternative to the second step, after the picker 130 descends to contact the object L and picks it up, the support pin 120 may be raised to the support member 110 in a raised position. Accordingly, the risk that the object L is damaged by the support pin 120 is reduced. That is, when the picker 130 descends and contacts the object L, the picker 130 descends a distance greater than the distance that the picker 130 must descend to pick up the object L, or the picker 130 is the object. Even if vibration occurs in the state of contact with (L), since the support pin 120 is not yet in the raised position, the object L and the holding member 10 may move inside the groove 111. That is, the groove 111 may be used as a free space for preventing damage to the object (L).

As a third step of the pickup process, the suction force is provided to the holding member 10 by discharging the air in the groove 111 through the intake hole 112 by the intake apparatus 20. Accordingly, the picker 130 picks up the object L and the holding member 10 moves inwardly of the groove 111, so that the holding member 10 is peeled off from the object L. In this process, the support pin 120 is still supporting the lower side of the object (L) by maintaining the raised position.

Thereafter, the picker 130 may move or rotate the object L picked up using a separate picker arm or a rotating arm. In addition, after the pickup is completed, the application of the suction force by the intake apparatus 20 is stopped, the holding member 10 is returned to its original state, and the support pin 120 also returns to the initial lowered position. Through this step, pickup of the object L is completed stably and smoothly.
