The reversing unit 160 is coupled to the base frame 201 and the base table 203 movably connected to the base frame 201.

The reversing unit 160 is provided with a vacuum ejector 204 for vacuuming the MLCC chip and a post 209 connected to the base table 203 is formed and the motor 208, And an MLCC chip mounting portion 207 are formed.

The motor 208 is connected to the drive pulley 402 and the drive pulley 402 is connected to be driven by the driven pulley 403 and the timing belt so that the driven pulley 403 is connected to the inverted block fixed shaft 407 And drives the inverted block fixing shaft 407 to rotate in accordance with the driving of the motor 208.

The rotation of the reversing block fixing shaft 407 reverses the position of each MLCC chip by rotating the reversing block 304 to which the MLCC chip connected to the leading end thereof is sucked.

The adapter 205 is connected to the adapter bridge 303. The adapter bridge 303 is engaged with the adapter 307 by being engaged with one side of the block 307 and connected to the other side of the adapter 307 and the inverted block fixing shaft 407, A spring 308 is positioned between the distal end surfaces of the first and second end portions.

The select shaft 305 is configured to repeat the spacing and contact with the inversion block 304 in the forward and backward direction according to the action of the cylinder 205 and the inverted block fixation shaft 407 is fixed by the spring 308 As shown in FIG. That is, the cylinder 205 is for driving the select shaft 305, and the inverted block fixing shaft 407 is fixed by the spring 308 even if there is a cylinder action.

The motor 208 is a driving source for rotationally driving the inverted block fixing shaft 407, which means rotation of the reversing block 304 and rotation of the MLCC chip. The cylinder 205 is a driving source for the forward and backward linear motion of the select shaft 305. This is a combination of the select pin 410 and the select shaft 305 for enabling rotation of the reversing block 304 and preventing rotation, And serves as an on-off switch for the rotation of the inversion block fixing shaft 407 which performs the separating action.

The select shaft 305 is spaced back and forth in accordance with the action of the cylinder 205 so that the select pin 410 makes the inversion block 304 rotatable or non-rotatable. When the select pin 410 is coupled to the select shaft 305, the reversing block fixing shaft 407 can not rotate due to the selection shaft 305 being fixed and the select pin 410 is separated from the select shaft 305 The reversing block fixing shaft 407 becomes rotatable.

6 is a structural perspective view of an inversion block unit of an MLCC chip reversal unit of an MLCC loader according to the present invention.

The inversion block 304 and the select block 502 shown in FIG. 6 are spaced apart from each other for convenience of explanation. In reality, the inversion block 304 and the select block 502 are in contact with each other, The select pin 410 and the pinhole 503 are separated and the select block 502 is separated from the inversion block 304. [

As shown in the drawing, a portion where the MLCC chip is mounted on the MLCC chip mounting portion 207 is referred to as the inversion block 304, and the inside of the inversion block 304 is connected to the select shaft 304 And an inverted block fixing shaft 407 is connected to a rear end of the inverting block 304. [

The first through fourth jig plates 511 through 514 are respectively coupled to the inverted block 304 on the outside of the square, the through hole is formed in the center of the select shaft 306 at the center, Four air connection grooves 518 are formed. O-rings 519 are inserted into the four air connection grooves 518, respectively.

A connecting air hole 515 is formed at the center of each of the four air connecting grooves 518 and each of the connecting air holes 515 is positioned at a position where it is in contact with the second air hole connecting hole 505 of the select block 502 And is connected to the second air hole connector 504 by the vacuum ejector 204. [

The selector shaft 305 includes a select shaft tube 501 connected to the cylinder 205 and a select block 502 formed at the tip of the select shaft tube 501.

The select axis tube 501 and the select block 502 are separated or coupled to the inversion block 304 according to the action of the cylinder 205. [

The select block 502 is separated from the inversion block 304 and the select pin 410 formed in the select block 502 and the pin hole 503 formed in the end face of the inversion block 304 And the inverted block fixing shaft 407 is placed in a rotatable state in a detached state.

The pinhole 503 is formed on the end face of the inverting block 304 and is spaced apart from the four air connection grooves 518 by an interval of 90 degrees and the select pin 410 is formed in a position corresponding to the pinhole 503 The select pin 410 is rotated in a state in which the select pin 410 is separated from the pin hole 503 and the four pin holes 503 are rotated while the inversion block 304 is rotated, The inverting block 304 is placed in an unrotatable state.

When the select block 502 is in contact with the inversion block 304, sealing is performed by the O-ring 591 and the select shaft tube 501, the first air hole connector 504, The MLCC chip may be sucked through the second air hole connecting hole 505, the air connecting groove 518, the lower surface air hole 516, and the first and second side air holes 517a and 517b.

The inverting block 304 is in the form of a tetragonal rectangular parallelepiped and the select block 502 is abutted on the end face and formed on the inner surfaces of the air connecting grooves 518 and the air holes 516, 517a and 517b.

In addition, the first to fourth jig plates 511 to 514 are attached to the outer four sides of the reversing block 304.

Each of the first to fourth jig plates 511 to 514 has a quadrangular shape with a quadrangular plate shape in the shape of a quadrangle plate, and chip setting portions 511a to 511c, in which the MLCC chips are located, 514a are formed.

The first to fourth chip set-up parts 511a to 514a are formed in a quadrangular shape so that the MLCC chip is positioned. On the side surface and the bottom surface, a lower air hole 516 for vacuum adsorption and first and second side air holes 517a And 517b are formed and connected to the air connection grooves 518, respectively.

When the first to fourth jig plates 511 to 514 are reversed to the positions in the upward direction by the rotation of the reversing block 304, the second air hole connector 505 of the select block 502 and the air connection groove (518) is brought into contact with each other to enable vacuum adsorption. That is, when any one of the first to fourth jig plates 511 to 514 is reversed to the upper side (when the first jig plate 511 is positioned on the drawing), only the corresponding jig plate is vacuum- .

The sizes of the first to fourth chip set-up parts 511a to 514a formed by the first to fourth jig plates 511 to 514 are different from each other.

In the case of the MLCC chip, the sizes of the MLCC chips are different from each other, so that the MLCC chips of various sizes can be commonly used by using one inverting unit by using one inverting block 304.

Since the first to fourth chip set-up units 511a to 514a are composed of four chips, it is possible to load four kinds of MLCC chips. The four kinds of MLCC chips do not mean four MLCC chips but can accommodate slightly larger or smaller ones based on MLCC chip having any one size according to the size.

Generally, the MLCC chip size is made up of four numbers, typically 1005, 1608, 2012 and 3216 MLCC chips. The four digits of these numbers indicate the first and second digits are horizontal, and the third and fourth digits are the vertical size and thickness. That is, 1005 has a width of 1.0 mm and a length of 0.5 mm (and thickness).

The first to fourth chip set-up units 511a to 514a of the inversion unit of the present invention are standardized so that 1005 MLCC chips, 1608 MLCC chips, 2012 MLCC chips and 3216 MLCC chips can be set, respectively, It also has a size that can set a slightly smaller or larger MLCC chip.

Therefore, the MLCC chips having different sizes can be stacked through one inverting unit.

For example, when loading 3216 MLCC chips, a large amount of 3216 MLCC chips supplied to the supply unit 150 of FIG. 1 are transported individually to the reversing unit 160 by the first grip unit 130.

The inverting unit 160 operates the select shaft 305 by the cylinder 205 to turn on the select block 502 by using the cylinder setting unit 511a to 514a in which the corresponding 3216 MLCC chip is located The selection block 502 is disengaged from the select pin 410 and the inverted block fixing shaft 407 is in a rotatable state.

At this time, according to the rotational driving force of the motor 208, the inversion block fixing shaft 407 rotates 90 degrees, and the inversion block 304 rotates by 90 degrees. When the chip set-up unit is placed on the upper side according to the rotation, the rotation is no longer necessary. When the chip set-up unit is not on the upper side, the chip set-

With the chip setup portion in place, the 3216 MLCC chips are transported to the collection unit 170 by the second grip unit 130 and finally stacked in the loading box or packing box.
