Description

[Detailed Description of the Invention] The present invention is used in a device (hereinafter referred to as a handler) for measuring and sorting workpieces such as semiconductor integrated circuits to supply the workpieces to a measuring section or to store the measured workpieces. This relates to an improvement of a magazine feeding device that supplies magazines to a predetermined position.0 Conventional magazine feeding devices sequentially take out and use the magazine located at the bottom of a plurality of magazines that are stacked and stored above. Since the lowermost magazine rests directly on the transport rail, only one magazine stock section can be provided which is stacked and stored one above the other.

On the other hand, the amount of magazines stored in the magazine stock section of the handler increases due to labor saving and speeding up of measurement, and the magazine stock section that only has one unit as in the past is running out of supply of magazines. ,...This has resulted in hindering the smooth operation of the roller. For this reason, there was a request for an increase in the amount of sudock in the magazine, but 1
In order to increase the stock amount with a magazine stock section that only has a base, the magazine stock section must be extended upwards, and this type of structure has the disadvantage that it is difficult to perform operations such as replenishing the magazine. As a result, it was practically impossible to increase the stock amount.

The present invention has been made to eliminate these drawbacks, and by arranging a plurality of magazine stock sections of conventional height in parallel, the overall soot storage amount can be increased by several times that of the conventional one, and the magazine stock size can be increased by several times. The present invention provides a multi-type magazine feeding device that requires the same amount of effort as conventional magazines.

Next, the present invention will be explained in detail with reference to the drawings according to examples. FIG. 1 is an external view of a handler incorporating the magazine feeding device of the present invention, in which A is a work supply section, B is a measurement section, and C is a work storage section. The magazine supply device of the present invention is mainly incorporated into a work storage section (unloader). 2 to 5 show the magazine feeding device of the present invention used as an unloader, and will be described in detail based on this embodiment.

The area surrounded by the two-dot chain line in FIG. 2 is related to the present invention, and the magazine filled with workpieces in the measuring section is pushed by the empty magazine and falls into the storage box. Base 4
A pair of poles 11 are erected on the top, facing each other across the length of the magazine 1, forming one magazine stock section 2. In this embodiment, two magazine stock sections are installed. The mutually opposing inner surfaces of the poles 11 are recessed vertically through the magazine storage groove 12, and the outer surfaces thereof are each provided with an oval-shaped swinging claw 7.
is pivoted with the upper end as the fulcrum.

A claw portion 14 at the lower end of this swinging claw passes through the elongated hole 13 of the pole 11 and protrudes from the inner surface of the pole, thereby locking the magazine 1 of the magazine stock portion 2. A swing lever 15 is fixed to a pivot shaft fixed to the swing claw 7, and a claw drive cylinder 16 whose one end is pivoted to a pole is connected to the tip of this lever. As shown in FIG. 3, the swing claws are located above the slide rail 17 laid on the base 4 at a distance of two or more magazines. The slide rail 17 is the base 4
At the top, one pole is laid in a direction substantially perpendicular to the line connecting the mutually opposing poles (center line of the magazine stock section), and at a position close to each pole between the poles.

A hole 18 passing through the magazine rail and the base 4 is drilled at the intersection of the slide rail and the center line of the magazine stock section, and the magazine holder at the tip of the rod of the cylinder of the lifting device 8 is inserted through this hole. The stand 19 protrudes from the upper surface of the slide rail and is recessed therein. This protruding height corresponds to the magazine 1 which is locked by the swing claw 14.
It extends to a position that is one magazine distance away from the bottom of the .

Next, the magazine transfer device 9 will be explained. A pair of magazine transfer grooves 20 are provided inside the slide rail 17 on the base 4.
A magazine block pawl 21 is slidably disposed through this groove. A slide bearing 22 is fitted to the bottom of the magazine block pawl.
A slide shaft 23, which is disposed parallel to the lower part of the magazine transfer groove, is inserted through this slide bearing. The two magazine transfer blocks provided along both of these magazine transfer grooves are connected to a connecting rod 24 at a slide bearing portion at the lower end thereof. A driving pin 27 protrudes from the connecting rod approximately at its center. On the other hand, on the lower surface of the base 4, a substantially L-shaped swinging arm 25 is rotatably supported by the base at its bent portion, and one end is provided with a U-shaped notch 26 to connect the connecting rod. A drive pin 27 is inserted therein, and a rod of a block pawl drive cylinder 28 whose one end is pivotally supported on the base 4 is pivotally supported at the other end.

These parts constitute the magazine transfer device 9. Next, the magazine fixing part 3 will be explained. Reference numeral 29 designates a positioning arm for accurately fixing the position of the entrance portion of the magazine 10, and has a magazine fixing groove 30 recessed in the lower surface of one end formed in an L shape, and the other end is pivotally supported on a base. The structure is such that the one end can move in the vertical direction. As shown in FIG. 4, this positioning arm has a lifting cylinder 31 whose one end is pivoted to a pole 11 adjacent to the positioning arm.
, Londo is centrally supported. A workpiece rail 32 and a workpiece number detector 33 are provided at the entrance of the positioned magazine. These parts constitute the magazine fixing part 3.

The magazine is extruded or bent from sheet metal and has a cross-sectional shape as shown in FIG. . When such a magazine 1 is inserted into the magazine storage groove 12 of the pole 11 with its both ends facing each other, the magazine inserted first has its lower opening groove 34 aligned with the pole 11.
It is locked by the claw part 14 of the swinging claw 7 attached to.

Magazines inserted after that are stored in a stack on top of the magazine. In this state, the slide rail 17-
1, there will be a space for more than two magazines.

When the handler is started in this state, first, the platform 19 of the magazine receiver of the lifting device 8 is raised and stopped at a distance of one magazine from the bottom surface of the lowest magazine. Next, the pawl drive cylinder 16 operates and the pawl portion 14 engages the elongated hole 1 of the pole.
When the 0-claw part 14 that moves the swinging pawl in the direction of detaching from the magazine 3 is removed from the magazine, the entire magazine is moved down to the platform 190 by one magazine, and the holder is stopped. Thereafter, the claw drive cylinder is operated in the opposite direction to insert the claw portion 14 into the lower opening groove 34 of the second magazine from the bottom, thereby preventing the magazines above the second one from falling. Then, the magazine receiver of the lifting device 8 lowers the platform 19 and places the magazine on the slide rail 17. The height range where the magazine is placed on this slide rail is the magazine transfer space 10.

When the magazine is lowered into the magazine transfer space in this way, the block claw drive cylinder 28 operates to rotate the swing arm 25 by a certain angle, and the magazine is normally stopped at the farthest position from the magazine fixing part 3. Transfer block claw 2
1 to transfer the magazine in the magazine transfer space to the magazine fixing part, and the magazine transfer block pawl returns to the original stopping position again.

On the other hand, when the magazine is transferred to the magazine fixing section, the elevating cylinder 31 operates, the positioning arm 29 rotates in the descending direction, and the leading end of the magazine is inserted into the magazine fixing groove 30.

In this state, the workpiece measured by the measuring part B slides down on the chute 36, passes through the workpiece rail 32, and slides into the magazine fixed to the magazine fixing part. At this time, the number of works detector counts the number of passed works, and when a certain number is reached, the above-mentioned series of magazine transfer operations are repeated until the next work is fed, and the magazine filled with works is now empty. It is pushed out by the magazine and falls into the storage box, replacing it with an empty magazine. At this time, the count number of the workpiece number detector returns to zero.

In this way, empty magazines are consumed one after another,
When one magazine stock section 2 becomes empty, it switches to the other magazine stock section 2 and repeats the same operation. This is because a magazine transfer space of 1° is provided at the lower end of each magazine stock section, so that any magazine unloaded from the non-stock section can be supplied to the magazine fixing section 3 without any problem. Further, in this embodiment, there are two magazine stock sections, but it is also possible to have three or more.

The above explanation is based on the case where this device is used as an unloader, but when used as a loader, all that is required is to replenish a filled magazine to the magazine stock section and eject an empty magazine, but the other operations are the same. 0 Note that the parts other than the part of the present invention divided by the two-dot chain line in FIG. 2 will also be briefly described for comparison. This part is a second classification for storing workpieces with different performance.

As described above, the magazine holder 19, which is the lowest layer stored in the magazine stock section 2, is lifted out by the magazine holder 19, and is fitted into the U-shaped transfer claw 38 having a magazine insertion groove 37 recessed in the upper surface, and then the magazine is fixed. Transfer to section 39. Next, the elevating device 8 is operated to remove the magazine 1 from the magazine insertion groove 37, and the magazine 1 is clamped by the positioning arm 29 as it is.

When filling of the workpieces is completed, the above-described operation is repeated, and the filled magazine is pushed by the left end of the U-shaped transfer claw 38 and comes directly below the filled magazine storage section 40. This special empty magazine is fed to the magazine fixing part by means of a U-shaped transfer pawl. On the other hand, the filled magazon is pushed up by the lifting device 8 and then stripped by the swinging claw 7. By repeating such an operation, the filled magazines are stacked from bottom to top. Note that this filled magazine storage section 40 may be arranged along the magazine fixing section within the two-dot chain line.

The series of operations explained above are all performed by the control section within the handler (
It operates sequentially in response to instructions from a processor using a program installed in a computer (not shown).

Since the present invention has the above-described configuration, a space for magazine transfer is formed between the lowest magazine and the base in each magazine stock section, so that the state in which magazines are filled in each magazine stock section is created. Even so, the magazine unloaded into the magazine transfer space will be supplied to the magazine fixing part without any problem, and multiple magazine stock parts can be installed in parallel, resulting in a reduction in the amount of magazine stock compared to before. , there is an advantage that the magazine supply amount increases dramatically and magazine replenishment becomes extremely easy.
