1 is a conceptual view showing a microchip gripper 100 according to an embodiment of the present invention.

The microchip gripper 100 according to various embodiments may refer to a transfer device for transferring a fine-sized electronic device.

The microchip gripper 100 according to various embodiments may include a fin plate 110, a hole plate 120, a fin 140, and an adhesive layer 130.

The pin plate 110 may be a basic skeleton of the microchip gripper 100, and one side thereof may be engaged with other devices.

For example, the pin plate 110 may be connected to a power source for operating the microchip gripper 100, or may be coupled to a robot arm (not shown) connected to a main body (not shown) of the microchip transfer apparatus. The other surface of the pin plate 110 may contact the pin 140 to support the pin 140.

The hole plate 120 may face the other surface of the pin plate 110 and be spaced apart from the pin plate 110 by a predetermined distance. For example, the hole plate 120 may be disposed in parallel with the pin plate 110, but spaced apart from the pin plate 110 and spaced apart. For example, the hole plate 120 may have a minute hole through which the fin 140 to be described later can pass. The hole plate 120 may include a plurality of holes, and the holes of the hole plate 120 may have a size and / or arrangement of electronic devices (e.g., microchips) to be held by the microchip gripper 100, As shown in Fig.

For example, when the electronic devices to be held are a rectangular pattern, holes of a rectangular pattern may be formed in the hole plate 120 corresponding to positions where the electronic devices are arranged, and when the electronic devices are circular patterns, Holes may be formed in a circular pattern in the hole plate 120 corresponding to the positions of the electronic elements. For example, in accordance with the position and the number of the holes, the transfer device 100 may include holes At least a portion of the electronic components of the wafer may be gripped. The hole plate 120 may include at least one protrusion 123 at a position corresponding to the position of the plurality of holes. The protrusion 123 may be formed at least partially protruding from the other surface of the hole plate 120.

According to various embodiments, the position of the protrusion 123 may overlap with the position of the hole, and a hole may be formed through the protrusion 123.

At least one or more holes may be formed corresponding to the number of protrusions 123. For example, a plurality of holes may be formed in one protrusion 123.

The projecting portion 123 may serve to press the adhesive layer 130 so that the electronic element and the adhesive layer 130 can be adhered to each other in the course of holding the electronic element by the adhesive force of the

adhesive layer

130, 140 may comprise a resilient material. For example, the fin 140 may include platinum, silver, nickel, copper, gold, or an alloy thereof. The pin 140 may be inserted and disposed at each hole formed in the hole plate 120, and may move through the hole. For example, when a plurality of holes are formed in the protrusion 123, one pin 140 may be disposed in each hole, and a plurality of pins 140 may be disposed on one protrusion 123, And through the hole.

The pin 140 may be formed at least partially longer than the distance from the other surface of the pin plate 110 to the other surface of the hole plate 120. For example, when one end of the pin 140 contacts the pin plate 110, the other end may protrude through the hole of the hole plate 120. For example, the other end of the protruded fin 140 may push out the adhesive layer 130 to reduce the area where the electronic element and the protrusion 123 of the hole plate 120 are bonded, Thereby reducing the adhesive force to the device.

At least a part of the bend 141 may be formed in the fin 140 corresponding to a predetermined space defined between the pin plate 110 and the hole plate 120. For example, the elastic force of the bending 141 can prevent the pin 140 from slipping off the hole plate 120 completely. For example, the bending 141 of the pin 140 may cause the pin 140 to bend, while the other end of the pin 140 provides an elastic force to push the adhesive layer 130 in the course of the adhesive layer 130 gripping the electronic device. So that it can be guided in the direction of deformation so as to be slid vertically through the holes in the hole plate 120. The adhesive layer 130 may be formed to cover at least a part of the other surface of the hole plate 120.

In addition, even if the hole plate 120 approaches the electronic elements, even if the electronic elements do not approach the plane in which they are placed, the at least some of the electronic elements may not be grasped.

2C, the protrusion 123 of the hole plate 120 presses the adhesive layer 130 and the electronic elements so that the respective electronic elements are bonded to the adhesive layer 130. As shown in FIG. can do. In this process, the projecting pin 140 may be pushed into the hole plate 120 at least partially by the bending portion 141.

2D, in the process of lifting the gripped electronic devices, the pins 140 are projected again to push the electronic devices, thereby reducing the area of adhesion between the adhesive layer 130 and the electronic devices .

For example, when the adhesive area of the adhesive layer 130 and the electronic device is maintained as shown in FIG. 2C, the electronic device may not be separated from the adhesive layer 130 in the process of separating the electronic device from the transfer device 100. The adhesive force between the adhesive layer 130 and the electronic device is lowered by reducing the area of adhesion between the adhesive layer 130 and the electronic device by pushing the electronic device from the pin 140.

The viscosity of the lead 210 disposed on the circuit board 200 is weaker than the adhesion strength between the adhesive layer 130 and the micro LED chip in the state of FIG. 2C, and the adhesive strength between the adhesive layer 130 and the micro LED chip in the state of FIG. It can be stronger than adhesion.

3A, the transfer device 100 according to an exemplary embodiment of the present invention aligns and positions the electronic elements (for example, micro LED chips) held by the lead 210 on the circuit board 200 .

So that the projection 123 of the plate 120 does not directly press the electronic element.

The adhesive force between the electronic element and the adhesive layer 130 may be similar to the adhesive force shown in FIG. 2D. The pin 140 of the transfer apparatus 100 pushes the electronic element to reduce the adhesive area between the adhesive layer 130 and the electronic element The adhesive strength may be in a weakened state. For example, when the electronic element is in contact with the lead 210, the viscosity of the lead 210 disposed on the circuit board 200 may be stronger than the adhesive force between the adhesive layer 130 and the electronic element shown in FIG. 3B. For example, the electronic device may be detached from the adhesive layer 130 and mounted on the circuit board 200.

For example, as the plurality of pins 470 press the electronic components 400, the bent portion is at least partially compressed, and the elastic force of the compressed plurality of pins 470 is lowered, 410).

The first plate 410 according to various embodiments may move up and down by an external driving force, and may be moved downward by an external driving force, but may be moved upward by using the elastic force.

The hole plate of the transfer apparatus according to various embodiments may include hole areas through which a plurality of pins can pass.

According to various embodiments, the hole plate may have a shape in which a second plate 432 and a third plate 434 made of different materials are attached together. For example, the second plate 432 may be formed of a material (e.g., metal, ceramic, glass, or the like) having excellent flatness characteristics, and the third plate 434 may be formed of a material ). For example, the second plate 432 may support the third plate 434 and allow the pins passing through the hole area to be perpendicular to the hole plate.

According to various embodiments, the hole plate can form a plurality of hole areas in consideration of the material characteristics of each plate.

For example, the hole areas of the second plate 432 may be formed through drilling in a step before the second plate 432 is mated with the third plate 434.

For example, the hole areas of the third plate 434 may be formed by attaching a third plate 434 to a second plate 432 having a hole area formed by a drilling method, And may be formed by irradiating the laser in the region direction. When the hole region is formed by the laser irradiation method, as shown in Fig. 7, the hole diameter in the direction in which the laser is irradiated can be formed larger than the hole diameter in the opposite direction.

For example, in the case of forming the hole plate by only the third plate 434 having the excellent adhesive property without the second plate 432, since the hole area is formed by the laser irradiation method, there is a problem that the hole diameter on both sides of the plate is wide Can be. For example, in the direction in which the hole plate is in contact with the electronic device, if the hole diameter is widened, the electronic device may be smaller than the hole area of the hole plate and may not be lifted. Further, if the hole diameter is wider in the direction in which the hole plate is opposed to the first plate, there is a problem that the pin is excessively shaken at the time of up-down movement and the position is changed.

According to various embodiments of the present invention, after the third plate 434 is attached to the second plate 432 having the hole area formed by the drilling method, the hole plate is attached to the third plate 434 The second plate 432 may be provided with an additional plate 436 having a hole area smaller in diameter than the hole area of the second plate 432 by a drilling method, They can be formed by cementing. Like the second plate 432, the additional plate 436 may be formed of any one of metal, ceramics, and glass.

According to various embodiments, the size of the protrusion of the third plate 434 included in the transfer device and the size of the hole area can be determined according to the size of the electronic device to be transferred and the size of the pin.

For example, since the electronic device must be attached to the protrusion of the third plate 434 and moved, the protrusion of the third plate 434 may be formed larger than the size of the electronic device. The size of the hole region may be larger than the size of the pin passing through the hole region. For example, the size of the hole region may be 100 to 120% of the size of the pin.

The hole area of the third plate according to an exemplary embodiment may be formed to have a predetermined size corresponding to the size of the fin. For example, the size of the hole region in the direction of looking at the protrusion of the third plate may be about 82 μm in diameter.

The size of the hole region in the direction facing away from the projection of the third plate according to an embodiment may be about 146 mu m in diameter.

When the third plate is formed of a material having excellent adhesion properties, for example, when PDMS is formed, a hole region is formed through a laser irradiation method so that the hole region on one side can be formed larger than the hole region on the other side have.

According to various embodiments of the present invention, although the one-side hole area of the third plate is largely formed, the second plate including the hole area formed to be smaller than the hole area of the third plate is attached to the third plate The excessive shaking of the pin can be prevented.
