Description

Upload method of module integrated circuit sorting machine and module integrated circuit sorting machine

The present invention relates to a module integrated circuit (Module IC) and the like, and in particular to a technique for detecting whether a module IC is loaded to a carrier.

A module IC (also known as a "module random accessor") is a device that fixes a plurality of integrated circuits (ICs) and other components to one or both sides of a circuit board. The independent circuit is an important part of the operation of the computer device and is expensive.

Therefore, rigorous performance testing must be performed after the product is manufactured and before it leaves the factory.

In order to test the module IC, in addition to the tester, a module IC sorter electrically connecting the module IC and the tester is required.

The module IC sorting machine performs the operation of loading the module IC to the carrier at the uploading position by a pick up device, and transferring the carrier loaded with the module IC to the test chamber through the transfer device (test The chamber IC is used to test the module IC loaded into the carrier, and the carrier loaded with the module IC for completing the test is transferred to the sorting position by another transfer device, and the module IC is unloaded from the carrier. The test results are classified, and the empty carrier from which the module IC is unloaded is transferred from the sorting position to the uploading position by another transfer device.

However, if the carrier does not completely empty the module IC at the sorting position The status is moved to the upload location, which adversely affects the load operation.

In addition, if other factors adversely affect the loading operation, the problem arises that the carrier at the loading position is transferred to the test chamber without being filled with the module IC. In addition, Korean Patent No. 355422 (invention name: semiconductor device experimental device) discloses a technology having an IC detecting sensor capable of sensing whether or not a test tray is loaded with a semiconductor element (hereinafter, referred to as "prior art") .

According to the prior art, the IC detecting sensor is disposed between the loading position and the unloading position, and includes a light source on the upper side and a light receiver on the lower side. Therefore, the prior art is formed to confirm whether or not the test disc is loaded with the semiconductor element in the procedure of transferring the test disc of the semiconductor element to the upload position at the unloading position, depending on whether the light is sensed by the light receiver.

However, it is difficult to directly apply the prior art to a module IC sorting machine.

The reason is that, for the test sorter supporting the test of the semiconductor element, as can be seen from FIG. 1a, the semiconductor element D loaded to the test disc has a wide horizontal area, so that the light source O and the light receiver I can be formed on the upper and lower sides. Perform a more accurate test. However, for the module IC sorting machine that supports the test of the module IC, as can be seen from FIG. 1b, the module IC M is loaded into the carrier while standing in a vertical state, so that a small horizontal area makes it difficult to perform by the prior art. Accurate detection.

Further, the prior art relates to a technique of detecting whether or not the test disc completely empties the semiconductor element on the way from the unloading position to the loading position, so it is difficult to detect whether the test disc is full of semiconductor elements at the loading position.

Further, as can be seen from FIG. 2a, for the module IC M, a direction groove DS for appropriately connecting the electrical connection terminal to the connected object and recognizing the correct direction of the connection terminal is formed on one side of the module IC M. Therefore, when the module IC M is loaded into the carrier in the state shown in Fig. 2b, the test failure is inevitably caused.

Therefore, for the module IC sorting machine, it is also necessary to automatically confirm whether the module IC is completely emptied from the carrier in the installation operation program. Further, it is necessary to confirm whether the module IC is loaded into the carrier or whether the module IC is in the correct direction. Loading to the carrier, but for the above reasons, it is difficult to apply the prior art to the module IC sorting machine.

A first object of the present invention is to provide a technique for confirming whether or not a module IC is loaded into a carrier in a module IC sorting machine.

Further, a second object of the present invention is to provide a technique capable of confirming whether or not a module IC is loaded into a carrier in a correct direction.

In order to detect the module integrated circuit loaded to the carrier, it is preferable to further include a direction detecting device mounted to the operating device.

Further, in order to achieve the above object, according to the present invention, a modular integrated body The circuit sorting machine includes: a carrier for loading and transporting the module integrated circuit; an operating device, the carrier is operated to be capable of loading the module integrated circuit on the carrier; and a direction detecting device for detecting Loading in the direction of the module integrated circuit of the carrier, wherein the direction detecting device is mounted on the operating device.

The direction detecting device includes a fixing member fixed to the operating device and a direction detector coupled to the fixing member. The fixing member has a convex portion that protrudes between the module integrated circuits loaded to the carrier. The protruding portion has a through groove located at a position in line with a direction groove formed in a module integrated circuit that is correctly loaded to the carrier. The direction detector includes a light emitting element coupled to one side of the fixing member and emitting light passing through the direction groove and the passing groove, and another side coupled to the fixing member, and is used for recognizing from the An identification component of the light of the illuminating element.

In addition, in order to achieve the above object, according to the present invention, a method for uploading a modular integrated circuit sorter includes: when the carrier is moved to an uploading position, operating the carrier using an operating device to load the modular integrated circuit The operation step to the carrier; the loading step of loading the module integrated circuit into the carrier; when the carrier integrated circuit is filled on the carrier, the carrier is operated to be capable of loading the module integrated circuit on the carrier And detecting an upload detecting step of loading the module integrated circuit; and when detecting that the module integrated circuit is filled on the carrier, releasing the step of releasing the operating state of the carrier.

<Example of operating device>

As described above, in order to mount the module IC on the carrier 300, the distance between the pair of plugs 331a-332a to 331p-332p facing each other is increased by applying an additional external force to the plugs 331a to 331p, 332a to 332p, In order to perform such a function, a special operating device 600 as shown in Fig. 6 is provided.

As shown in FIG. 6, the operation device 600 is formed to include an operation panel 610 and a lifting source 620.

The operation panel 610 can be lifted and lowered, and has 2 × 16 guide bars GB1a to GB1p, GB2a to GB2p thereon. The 2 × 16 guide bars GB1a to GB1p, GB2a to GB2p are respectively inserted into the guide grooves GG formed on the bottom surfaces of the 2 × 16 plugs 331a to 331p, 332a to 332p of the carrier 300 as 2 × 16 plugs The functions of the main body of the external force in the outward direction are applied to 331a to 331p, 332a to 332p.

As can be seen from the reference drawing of Fig. 7, when viewed from the plane, the centers (Ca) of the guide bars GB1a to GB1p, GB2a to GB2p are outwardly deviated from the center Cb of the guide grooves GG of the plugs 331a to 331p, 332a to 332p. A certain distance S. Further, the guide bars GB1a to GB1p, GB2a to GB2p have a shape in which the outer diameter gradually increases in the lower direction. Therefore, as in the reference drawing of Fig. 8, when the operation panel 610 is raised, the sharper end portions of the guide bars GB1a to GB1p, GB2a to GB2p are inserted into the edge portion of the guide groove GG, and the plugs 331a to 331p, 332a are started. The force to the outside direction is applied to 332p.

The lift source 620 functions as a movement source that moves the operation panel 610 up and down.

Here, the lift source 620 is configured to pass when the operation panel 610 is lowered The operation panel 610 is successively lowered in two stages. Such a lift source 620 can be constructed from a motor or a plurality of cylinders.

In the carrier 300 and the operation device 600 having the above structure, the operation of the operation device 600 to operate the carrier 300 to load the module IC to the carrier 300 or to release the operation of the carrier 300 will be described below.

When the elevation source 620 is operated such that the operation panel 610 is raised, the guide bars GB1a to GB1p, GB2a to GB2p of the operation panel 610 are inserted into the guide groove GG, and the plugs 331a to 331p, 332a to 332p are pushed to the outer direction; when the operation is reached When the operation of the apparatus 600 is completed, the plugs 331a to 331p, 332a to 332p are pushed to the outside as much as possible, so that the module IC can be loaded on the carrier 300.

Further, when all of the 16 module ICs are loaded on the carrier 300 by the pickup device (not shown), the elevation source 620 operates, causing the operation panel 610 to be slightly lowered by one stage, whereby the plugs 331a to 331p, 332a to 332p pass When the springs 341a to 341p, 342a to 342p are moved in the inward direction, the two ends of the loaded module IC are elastically pressed, thereby firmly fixing the module IC, and then the lifting source 620 is operated, so that the operation panel 610 is operated. Completely down.

<Example of loading and direction detecting device>

Referring to FIG. 9, the loading and direction detecting device 900 is formed to include a fixing member 910, 16 loading detectors 920a to 920p, and a direction detector 930.

Referring to Fig. 10, the fixing member 910 is provided to be fixedly mounted to the operation panel 610 of the operation device 600, and more specifically, to the columns of the guide bars GB1a to GB1p, GB2a to GB2p arranged in two columns of 16 columns per column. With columns between. This fixing member 910 has a convex portion PP protruding from between the modules IC M loaded to the carrier 300. Further, the convex portion PP has a plurality of through grooves PS which are positioned neatly in a position on the same straight line as the direction groove DS formed in the module IC M.

Here, if the straight-lighting performance of the light-emitting element 931 and the identification element 932 of the direction detector 930 described later is good, it is not necessary to manufacture the through-grooves PS of the convex portion PP and the convex portion PP. However, the detector with good straightness is expensive, and the detector with low price has a diverging property, so in order to block the diverging portion of the light-emitting element when using a low-cost detector, there should be a protruding portion PP for further Accurate detection.

The 16 load detectors 920a to 920p are coupled to the convex portion PP, and have a pair of light-emitting elements 921 and identification elements 922.

Alternatively, according to an actual embodiment, instead of the 16 loading detectors being coupled to the protruding portion PP, the 16 loading detectors 920a to 920p may be directly fixedly set to the operation panel independently of the protruding portion PP.

The light-emitting element 921 and the identification element 922 are respectively coupled to the convex portion PP on both sides with the module IC M interposed therebetween, wherein the lower end portion of the module IC M is inserted into the recess formed between the convex portions PP Detection slot SS. Here, the light-emitting element 921 disposed on one side emits light, and the identification element 922 disposed on the other side recognizes light from the light-emitting element 921. Therefore, when the light emitted from the light-emitting element 921 is recognized by the identification element 922, it is detected that the module IC M is absent; when the light emitted from the light-emitting element 921 is not recognized by the identification element 922, it is detected that the module IC M is present.

The direction detector 930 also has a pair of light-emitting elements 931 and identification elements 932, the light-emitting element 931 is coupled to one side end of the fixed member 910, and the identification member 932 is coupled to the other side end of the fixed member 910. The light-emitting element 931 emits light passing through the direction groove DS and passing through the groove PS, and the identification element 932 recognizes the light emitted by the light-emitting element 931. Therefore, when the direction of the 16-chip module IC M inserted into the detecting slot SS is correctly aligned, the light emitted from the light-emitting element 931 is recognized by the identifying component 932; even in the 16-chip IC M, even When more than one module IC M is in the wrong direction, the light emitted from the light-emitting element 931 will not be recognized by the identification element 932.

Continuing, a module IC sorting machine including the carrier 300, the operating device 600, and the loading and direction detecting device 900 having the above-described structural components will be described with reference to the flowchart of FIG.

<Example of installation method>

1. Operation <S111>

When the empty carrier 300 is transferred to the loading position, referring to FIG. 12, the operation panel 610 is raised and the carrier 300 is operated by the operation of the operating device 600, so that the paired plugs 331a to 33p, 332a of the carrier 300 facing each other. The pitch to 332p is increased, so that the module IC M can be loaded to the carrier 300.

2. Unload detection <S112>

In a state where the carrier 300 is operated by the step S111, the loading detectors 920a to 920p operate and detect whether the module IC M is completely unloaded from the carrier 300 located at the current uploading position in the previous unloading operation program, thereby causing the carrier 300 The module IC M is completely emptied.

If it is detected that the carrier 300 does not completely empty the module IC M, the module IC sorter generates an interrupt (JAM); if it detects that the carrier 300 completely clears the module IC M, it proceeds to the next stage.

3. Load <S113>

A separate pick-up device (not shown) is run for the carrier 300 that empties the module IC M, as shown in Figure 13, thereby loading a new module IC M.

4. Upload detection <S114>

When the pickup device completes the job, in a state in which the module IC M can be loaded with the carrier 300 (i.e., the state in which the operation panel is raised), the load detectors 920a to 920p are re-run to detect whether or not the module IC M is loaded.

If the module IC M is not detected by any of the 16 load detectors 920a to 920p, an interrupt is generated; if all of the 16 load detectors 920a to 920p detect the module IC M, the next stage is performed.

5. Release <S115>

When the module IC M is filled, as shown in FIG. 14, the operation device 600 lowers the operation panel 610 by one stage by the operation to the extent that the operation state of the carrier 300 can be released, thereby releasing the operation state of the carrier 300. The direction detector 930 is lowered and aligned with the DS, and can detect the loading direction of the module IC M. If the operation panel 610 is completely lowered, the loading direction of the module IC M cannot be detected by the direction detector 930 coupled to the operation panel 610, so the module IC M is detected only by the direction detector 930 coupled to the operation panel 610. The degree of loading direction is reduced by one stage.

6. Direction detection <S116>

The operation of the carrier 300 is released by one stage of lowering through the operation panel 610. In the state, it is detected by the operation of the direction detector 930 whether the loading direction of the 16 modules IC M loaded to the carrier 300 is correct.

If the identification element 932 of the direction detector 930 does not recognize the light emitted from the light-emitting element 931, an interruption occurs; if the identification element 932 of the direction detector 930 recognizes the light emitted from the light-emitting element 931, it proceeds to the next step.

Of course, although it is also possible to perform the direction detection before the carrier 300 is released, as in the present embodiment, it may preferably be implemented to perform the direction detection after the operation of the carrier 300 is released. The reason is that before the carrier is released, the module ICs are not properly aligned and fixed to the plug, and the direction slots of the module IC may not be on the same line.

7. Fall <S117>

When the loading direction of the module IC M is all correct, the lifting source 620 is again operated to completely lower the operation panel 620.

In addition, when the operation of releasing the carrier after the direction detection is realized, in the above-described flow, the loading detecting step and the direction detecting step may be simultaneously performed, or alternatively, the direction detecting may be performed before the loading detection. Further, according to the device structure, the size of the loading detector and the direction detector, and the setting position, it is possible to sufficiently perform the load detection and the direction detection after the operation of releasing the carrier first.

In addition, the above description has been described by taking a case where the relationship between the carrier 300 of FIG. 3 and the operating device 600 of FIG. 6 is taken as an example.

However, it can be understood that the module IC having the carrier and applying the operating device The sorting machine can apply the loading and direction detecting device 900 of FIG. 9 and can also apply the same mounting method as the flow of FIG. 11, wherein the carrier is used for carrying in the state of the loading module IC M, the operation The device is capable of operating the associated carrier in a state in which the module IC is loaded on the associated carrier.

Accordingly, the present invention has been described with reference to the embodiments of the accompanying drawings. The equivalents are intended to explain the scope of the invention.
