rails 24 is properly adjusted by rotating the width adjustingscrew shaft 25 which is driven by themotor 26 via thebelt 27. - As shown in FIG. 4b, the strip A which has been transferred to the
drawer unit 20 from the on-loader unit 10 is then retained on thepicker head 37 by using thesuction portion 31 which applies the suction vacuum force from thevacuum port 39. - The
reciprocating transferring member 35 with the strip A retained on thepicker head 38 moves along theguide rail 36 to transfer the strip A to the cutting device D which will cut the strip A into the plurality of individual package devices. - Next, the package device C transferred by the
picker head 37 of thestrip transferring unit 30 is cut into the plurality of individual package devices by the cutting device D. - After the strip A has been cut into the plurality of individual package devices in the cutting device D, the latter are retained on the
picker head 38 of thestrip transferring unit 30 by the suction vacuum force. Then, thereciprocating transferring member 35 transfers the individual package devices to thecleaning unit 40. - On the other hand, the pair of picker heads37, 38 are vertically moved by the vertical movement of the
picker transferring member 32 which is achieved with anut 33 connected to themotor 34. - The individual package devices C retained on the
picker head 38 of thestrip transferring unit 30 are seated on theupper plate 43 of thecleaning unit 40 under the cushioning function of the O-ring 42. - In the
cleaning unit 40, in order to allow the alien material to be removed from the individual package devices C, thebrush 44 fixed to the transferringblock 46 which moves horizontally by the power source (not shown) is used. Further, a high pressurized air supplied to theair nozzle 45 through theair pipe 47 is applied to the individual package devices C to separate the alien material from the same which are retained on thepicker head 38 of thestrip transferring unit 30 by the suction vacuum force. - Next, the individual package devices C retained on the
picker head 38 of thestrip transferring unit 30 by the suction vacuum force is transferred to theupper plate 49 b of thepackage drying unit 48 adjacent thecleaning unit 40. The individual package devices C are seated on theupper plate 49 b. - In this situation, the
heating member 49 c mounted between theupper plate 49 b and the main body of the dryingunit 49 heats the individual package devices C in order to remove the humidity from the them. At the same time, the vacuum pressure from thevacuum path 49 e further removes the remaining humidity on the individual package devices. - Next, the individual package devices from which the alien material and the humidity are removed in the
cleaning unit 40 and thepackage drying unit 48 arrives at thepackage deposit unit 60. - The individual package devices C positioned on the
upper plate 49 b of thepackage drying unit 48 are transferred to thepackage deposit unit 60, being picked up by the suction vacuum force by the pick-uphead 52 of the package pick-upportion 51 of thepackage transferring unit 50. - Next, half of the individual package devices C are released from the pick-up
head 52 by partially stopping the suction vacuum force and then are retained and fixed on thedeposit zone 61 d of thefirst deposit place 61 a of the upper deposit table 62 by the suction vacuum force. - Next, after the half of the individual package devices C are fixed on the
first deposit place 61 a, thepackage transferring unit 50 horizontally moves the pick-uphead 52 to locate the pick-uphead 52 above thesecond deposit place 61 b. - Then, the suction vacuum force is not applied any longer by the pick-up
head 52 and the remaining individual package devices C are then retained on thedeposit zone 61 d of thesecond deposit place 61 b of the upper deposit table 62 by the suction vacuum force. - The suction vacuum force applied to the first and the second deposit places61 a, 61 b is transmitted from a
vacuum path 61 h through thevacuum recess 63 a, thevacuum hole 63 b and thevacuum pipe 64. - During the individual package devices C are seated on the
deposit zone 61 d, theinclined portion 61 e smoothly guides the package device C to enter into a proper position within the deposit zone, even if the package device C poses in inappropriate orientation. - Further, although a maximum width of the
deposit zone 61 d is longer than that in the prior art, thedeposit zone 61 d has thevacant zone 61 c in its adjacent area, thereby preventing the adjacent deposit zones from being interfered with each other. - That is, in the present invention, the individual package devices C are alternatively positioned in the first and the second deposit places61 a, 61 b.
- As shown in FIG. 8g, since the angle a of the inclination of the
inclined portions 61 e ranges from 20 degree to 40 degree, it is possible for the individual package device to be smoothly seated. - When the individual package device C is seated on the
deposit zone 61 d, since a BGA (Ball Grid Array) 2 is positioned on an upside of the individual package device C and the bottom surface of the individual package device C comes into a contact with acontact surface portion 61 f protruding above thedeposit zone 61 d, the suction vacuum force is efficiently applied to the package device C. - The deposit table61 is horizontally moved along the deposit table guiding rail 68 by driving the driving
motor 69 to rotate thescrew shaft 67 whose rotation moves horizontally thenut member 66, before the package device C is deposited on the deposit table 61 or after the package device C has been deposited on the deposit table 61. - Next, the package pick-up
unit 70 moves to the package deposit table 61 and then the package device C are retained on the pick-uphead 72 by the suction vacuum force to be horizontally transferred. The pick-uphead 72 is fixed to the vertically transferringblock 73 moving along the vertical guidingrail 74 and is supplied with the negative air pressure from theair cylinder 71. - The rotation of the
screw shaft 76 by the power source (not shown) horizontally moves the pick-uphead 72 and the vertically transferringblock 73 along the horizontal guiding rails 77. - The pick-up
head 72 retaining the package devices C is transferred to the visual inspection means 90 shown in FIG. 1a along the horizontal guiding rails 77; and the package devices C are subject to an inspection where the condition of the package device, e.g., the result of the marking or chipping which determines the quality grade of the package device C are examined. - At this time, the individual package devices C retained on the pick-up
head 72 are classified into e.g., a good state and a bad state, based on data of the predetermined quality standard which may be stored in a microprocessor (not shown) and then are separately transferred to the packagetray deposit unit 80 mounted on one side of the visual inspection means 90. - In the package
tray deposit unit 80, the individual package devices C retained on the pick-uphead 72 are transferred to the plurality oftray deposit portion 82. According to the state of the individual package device C, the package devices C are separately deposited on thetray deposit portion 82 for the good state or thetray deposit portion 82 for the bad state. - That is, the package
tray deposit unit 80 has the plurality oftray deposit portions 82 in order for a distinguished deposit based on the quality of the package device C. - On the other hand, after the package devices C are classified into the good state and the bad state by the visual inspection means90, the tray B fixed on the
tray deposit portion 82 by theair cylinder 81 is moved along the guidingrail 84 for the selective deposition of the package device classified into the good state and the bad state. - Next, the
package transferring unit 50 approaches the tray B on which the package devices are deposited and holds the tray B through the tray pick-upportion 55 having thetray clamp 54 holding the sides of the tray B, depositing the tray B vertically in thetray deposit cassette 89 of the tray supplying portion 99. The vacant tray B is positioned again on thetray deposit portion 82. These operations are repeated. With this manner described, cutting the strip, cleaning and drying the package device, seating the package device on deposit table, inspecting the package device and classifying the package device, and selectively depositing the classified package device constitutes one cycle of the process. - Consequently, by the inventive handler system, a semi-finished product on which a plurality of packages are arranged and strips can be easily cut by a cutting device, e.g., a sawing machine, and a quality inspection is performed to find an inferior one after each of the separated package devices is cleaned and dried, so that the package devices can be separately deposited on a basis of the inspection result, whereby the manufacturing of the semiconductor package device is efficiently processed.
- Although the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
