Detailed description of the invention

The present invention is a sorter to transfer the IC products in the tray loader or tube loader in the MBT (MONITORING BURN-IN TESTER) test process of IC products to be classified by insertion departure and grade The present invention relates to a dual process that transfers and inspects IC products in a stacker by two, so that a large number of products can be classified in a short time.

In general, IC product classifiers are widely used in tray type and tube type method. The classifier used in the past operates the cam by simply inserting and transferring IC products. Because of this method, there was a disadvantage that the function of the classifier could not be expanded, and this resulted in a complicated structure and a need for skilled workers to operate the equipment, and only one IC product was transported for one-time operation of the classifier. It takes a long time to work, there was a problem that will cause a big problem in mass production of the product.

On the other hand, in order to solve the above problems, a dual system type sorter for transferring and classifying two IC products has recently been devised, but the above method has two feed slots for transporting a servo motor to an IC product in a loader. After retrieving and storing it in a spare pocket, the sorter operated in this state to inspect and sort IC products.

In other words, the transfer port transfers the IC product from the loader and inserts it into the spare pocket, and then transfers the IC product to the centering part from the loader and inserts it into the pocket. In this state, if one IC product is defective, the conveying part installed at the upper part flows, and one of the two conveying ports installed in the conveying part is operated to draw out one IC product from the spare pocket. The other transfer port draws out the defective IC product and returns to the original state. The defective IC product is discarded and the IC product drawn out from the spare pocket is inserted into the pocket of the centering part and fixed. It was made to be able to transfer two by one.

However, the above method has the disadvantage that other devices should stop working when the IC product is stored in the spare pocket. Also, if the IC product in the spare pocket is consumed, the other device is stopped again and the other equipment is in the reloader. There is a disadvantage in that unnecessary time is consumed because the IC product is taken out and inserted into the spare socket. Therefore, the IC product is classified into a large amount because other devices have to stop working to insert and store the IC product in the spare pocket. There was a serious waste of time.

In order to solve the above problems, the inventors have recently invented and filed an automatic classifier capable of transferring and classifying two IC terminals (1996 Patent Application No. 11049). Transfer part by installing DC test part and insert removal work part (INSERT REMOVE part), standby pocket part (WAIT pocket part) and defective part (DC REJECT part), and several drawers for picking up or inserting IC on the upper part But each drawer is composed of two, each operated by the servo motor installed in the upper, the centering pocket is composed of the left and right flow unit and the front and rear flow unit and the take-out and seating unit This is done by installing the operating part.

Referring to the effects of the present invention configured as described above are as follows.

As shown in Figs. 5 and 6, the board on which the IC product is inserted is placed on the tray loader, and the board loader is installed on the XY table and the body 1 is operated in this state. Then, the trays are dropped one by one from the supply unit 4 installed on one side of the front surface of the main body 1, and the trays are transported on the work line by the transfer unit 5 in a state fixed by the fixing unit 5. Done.

When the tray containing the IC is positioned on the work line as described above, the tool and the removable part installed in the insert part INSERT installed in the upper part of the main body 5 are installed in the tool part REMOVE. The tool operates simultaneously, feeding and feeding two IC terminals.

In this state, the tool in the remote portion lifts the IC terminal from the tray and simultaneously the tool in the insert portion lifts the terminal from the tray and inserts it into the pockets 65 and 65 'of the centering processor 11. The tool on the remote part picks up the IC terminal on the board and inserts it into the classification pocket.At the same time, if the tool in the classifier is a normal product according to the IC rating, the tool descends on the upper part of the pocket. Lifting and then moving to one side and inserted into the pocket, if the two products are all defective, the sorter part 111 sorted into several after lifting the product by lifting the tool of the empty feeder 13 according to the grade of the defective It will be fed to the tray of.

On the other hand, if one of the products classified in the board loader is defective in the above condition, the defective IC terminal transfer tool installed in the middle part moves left and right to pick up the defective product, and then moves left and right to install on one side. It is supplied to the conveying device and the defective product is transported to one side by the conveying device and then seated on the tray according to the degree of defect by the tool of the sorter unit 111.

In this state, if one of the two IC terminals is defective, the pocket is transferred to one side by the empty process 15. In this state, the tool installed at the top picks up the defective IC terminal and makes the pocket empty. .

If the failure occurs in the above condition, the pocket is retracted again, and at the same time, the normal terminal is picked up by another tool to make the pocket empty, and the tool holding the normal product in the empty pocket is inserted into two. When the pocket is returned to its original position, the two parts are transferred again by the tool of the rib.

Meanwhile, as shown in FIG. 7, the tray sorter is installed on the cylinder rod when the cylinders 19 and 19 'installed before and after the trays are stacked on the tray seat 17 are operated. The operating plate 20 is transferred to the upper portion by the guide rods on both sides, and at the same time, the pusher 22 installed on the operating plate 20 is pushed upward to push the roller 23 installed on the outside. Due to this, the lower part of the fastener 24 is pushed while rotating about the pin, and the fastener 24 having the lower part of the tray mounted on the upper part is installed while the tray is lowered to the lower part of the tray. At the same time, if one tray falls, the cylinders 19 and 19 'are returned to their original positions, and the fixture 24 is inserted into the groove formed at the lower end of the upper tray to be fixed. Will be.

When the tray is supplied from the supply unit 4 as shown in FIG. 8, the cylinder 25 installed on the outside of the flow rails 2 and 2 'is operated, and at the same time, an operating rod connected to the cylinder 25 ( 26 is flowed upward by the connecting bar (27).

That is, when the cylinder rod is pulled out by the cylinder 256, the distance between the cylinder 25 and the connecting bar 27 fixed to the operating rod 26 becomes long, which causes the connecting bar 27 to operate the operating rod 26. Because it is fastened to the eccentric), the operating rod 26 is moved upward to one side while drawing a semi-circle toward the top.

As shown in FIGS. 10 and 11, when the tray is positioned on the upper plate 20, the actuating rod 26 is moved upward by being operated by the cylinder 25, and at the same time, the support rod 35 of the main body 1 is supported. Fasteners 34 installed on the upper plate 30 to the rollers 36 are installed to the upper portion, thereby the roller 36 is inclined portion formed in a multi-stage on one side of the fasteners 34 ( 33) and pushes the fixture 34 by pressure and the fixture 34 is to fix the tray while flowing inward.

When the tray is fixed as described above, the sub-motor installed on the side of the main body is operated, and the ball screw shaft 3 fastened to the operation support 38 of the fixing part 5 fixing the ball screw and the tray. As a result, the tray fixing part 5 is moved on the work line on which the tool is installed by the rail provided at the lower end thereof.

On the other hand, the transfer part for transferring the ball screw (3) and the fixing part (5) when the shaking portion between the screw shaft and the rail fixing the tray (50 when the tray is fixed by the sub-motor to move the movement occurs) 28) The shaking occurs during the rotation of the ball screw, the rapid stop, and the shaking caused during the transfer of the fixed part 5, causing the plate screw or the plate on which the feeding part is installed to shake, resulting in an overload of the ball screw. This will cause severe wear and shorten the life of the device.

When the above shake occurs, the shake is absorbed by the automatic adjustment device 8 as shown in FIGS. 13 and 14. That is, the operating support 38 which is fastened to the ball screw 3 is shaken, and at the same time, the operating support 38 moves to one side by the guide roller 42 fixing the middle part of the operating support 38. The roller 39 installed at the end flows in the fixing hole 40 to coincide with the center line of the ball screw.

In more detail, a fine tolerance is formed between the guide roller 42 supporting the operation support 38 and the intermediate part and the roller 39 and the fixing hole 40 installed at the end of the operation support 38. Since it is assembled, it absorbs the vibrations to match the center line between the drive shaft and the driven shaft, minimizing mechanical wear, enabling quiet operation, and automatically arranging the airway shaft and the load shaft automatically. It is to be able to move left and right.

As shown in FIG. 12, the operation is performed when the number of inserting IC terminals formed in the tray is an odd number. 49) The tool is located outside the tray line and is located outside, and if the insertion groove of the tray is odd, the transfer tool transfers two IC terminals in the tray one by one. The tool is rotated in the tray direction by the cylinder 49, and in this state, the left and right transfer cylinders 45 are operated toward the position of the IC terminal of the tray to move the pedestal 47 to one side.

That is, when the left and right transfer cylinder 45 is operated, the flow hole 48 is transferred to one side from the guide rail 46 installed on the pedestal 47, and at the same time, the upper and lower portions are installed on the upper part of the tool. The working cylinder 49 is activated so that the tool is positioned on top of the IC terminal.

When the tool is positioned above the IC terminal as described above, the IC terminal is fixed by the adsorption device installed on the tool, and then the tool is returned to its original position in the reverse order as described above, and then placed in the standby pocket 43. When the transfer tool transfers the IC terminal of the next compartment and is absorbed again, transfers the IC terminal in the standby pocket 43 to one side of the remaining IC terminal again so that the transfer tool can pick up two. Will be done.

When a defective IC terminal occurs as shown in FIGS. 22 and 23, the tool transfers the IC terminal on the burn-in board to reach the empty process 15, and at the same time, the IC terminal is rotated by the empty transfer tool 14 for rotation. The operating rod 53 is positioned above the operating rod 53 and at the same time the rotary cylinder 56 is operated to transfer the operating rod 53 fastened between the guide rails 52 to one side.

That is, when the rotary cylinder 56 is operated, the rotary plate 57 installed on the rod of the rotary cylinder 56 rotates, thereby causing the bearing 58 fastened to the upper end of the rotary plate 57 to operate the rod 53. The rail is installed vertically in the middle of the rail is to be transferred to one side while rotating. At this time, the operating rod 53 is positioned at the lower end of the IC terminal by the bearing 58 installed on the rotating plate. In this state, the left and right transfer cylinder 62 is operated to be installed at both sides of the cylinder 62. The pedestal 64 is transferred to one side.
