Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin sealing device for electronic parts such as an IC, which automatically seals electronic parts.

[0002]

2. Description of the Related Art An electronic component such as an IC has a main body, such as a lead frame, which is resin-sealed with an epoxy resin or the like. Since electronic components are manufactured in a clean room and contamination such as dust must be avoided as much as possible, it has been conventionally performed that resin encapsulation is performed automatically by a resin encapsulation device that is entirely covered with a cover. .

FIG. 19 schematically shows an example of a conventional resin sealing device of this type. In the figure, 1P is a lead frame stock part, 2P is a preheater, 3P is a tablet stock part, 4P is a loading mechanism, 5P is a transfer molding machine, 6P is a cleaner, 7P is an unloading mechanism, 8P is a gate break mechanism, and 9P. Is the product stock department, 10
P is a cover that covers the entire device. Then, the lead frame stock portion 1P is loaded with the lead frame before resin sealing, and the tablet stock portion 3P is loaded with the epoxy resin tablet. These loads are done manually.
The lead frame is first conveyed from the lead frame stock section 1P to the preheater 2P and is preheated there.
Then, the preheated lead frame and the tablets of the tablet stock section 3P are carried into the transfer molding machine 5P by the loading mechanism 4P. Next, in this transfer molding machine 5P, a resin sealing portion is molded on the lead frame. After this molding, the resin-sealed product is unloaded from the transfer molding machine 5P by the unloading mechanism 7P. Furthermore, in the gate break mechanism 8P, the resin sealing portion of the product and the resin of the runner portion are cut and separated. Then, only the product is carried into the product stock section 9P. The above steps are repeated. The cleaner 6P is a transfer molding machine.
It is for cleaning the 5P mold.

Conventionally, such a fully automatic resin sealing device has only one transfer molding machine 5P. However, in transfer molding with an epoxy resin, which is a thermosetting resin, after the mold is closed, the resin is filled into the mold cavity for molding the resin sealing portion of the electronic component from the shot cavity, and then this filled resin is filled. In order to surely cure the resin, it is necessary to take a curing time of, for example, about 1 minute. The mold can only be opened after this cure time. Therefore, the operation cycle of the transfer molding machine 5P is limited by the cure time, and there is a limit to its shortening. Therefore, the transfer molding machine
Even if the operation speed of each mechanism other than 5P can be increased, the operation cycle of the entire resin sealing device is limited by the operation cycle of the transfer molding machine 5P, and there is a limit to shortening.

[0005]

As described above, in the conventional resin sealing device for electronic parts, since there is only one transfer molding machine, it is difficult to shorten the operation cycle of this transfer molding machine. There is also a problem that the efficiency cannot be improved by giving a great restriction to shortening the operation cycle of the entire resin sealing device. Of course, if a plurality of resin sealing devices are used, the efficiency can be improved as a whole, but it is space-consuming and costly.

The present invention is intended to solve such a problem, and it is possible to improve the operation efficiency regardless of the difficulty of shortening the operation cycle of the molding machine, and to provide a compact and inexpensive electronic component. An object is to provide a resin sealing device.

Then, in this molding machine, the resin sealing portion is molded with respect to the insert. Thereafter, the product in which the insert is resin-sealed is transported from the molding machine to the product stock section by the product transport mechanism. By the way, although there are multiple molding machines, inserts and resin materials are carried into these molding machines from a common stock section by a common transport mechanism, and products are transferred to a common product stock section by a common product transport mechanism. Are unloaded. At this time, the operation cycles of the plurality of molding machines are deviated from each other. This allows
Even if the operating cycle of each molding machine cannot be shortened due to the curing time, the operating efficiency of the entire resin sealing device can be improved.

For example, as in the resin sealing device for electronic parts according to the second aspect of the present invention, while the resin sealing portion is being molded by a certain molding machine, the product is carried out by the other product molding machine by the product conveying mechanism. Then, the insert material and the resin material may be carried in by the insert material carrying mechanism and the resin material carrying mechanism.

Further, in the resin sealing device for electronic parts according to the third aspect of the present invention, in the insert conveying mechanism, the insert is transferred while being aligned from the insert stock portion to the insert aligning table. Further, in the resin material transport mechanism, the resin material is transferred from the resin material stock section while being aligned on the resin material alignment table. Then, the common common transport mechanism holds the inserts aligned on the insert aligning table, holds the resin material aligned on the resin material aligning table, and carries the resin material into the molding machine. After molding, the same common transport mechanism carries the product out of the molding machine. As described above, it is possible to transfer the inserts or the resin material to the insert alignment table or the resin material alignment stand while the common transfer mechanism is performing the transfer.

A horizontal pedestal 4331 that is removably inserted into the storage magazines 42 and 421 through the opening 411 of the magazine base 41 is fixed to the upper end of the storage lifter 433.

As described above, there are two transfer molding machines 3A and 3B. However, for the two transfer molding machines 3A and 3B, another lead frame stock section 1 is used.
The tablet stock unit 2, the product stock unit 4, the lead frame transport mechanism 5, the tablet transport mechanism 6, the product transport mechanism 7, the gate break mechanism 8 and the like are shared. And these are control means such as computers.
This control means 01 shifts the operation cycle of both transfer molding machines 3A and 3B from each other by half of the cycle, and molds the resin sealing portion S with one molding machine 3A and 3B. While the molding machine 3B, 3A, the product transfer mechanism 7
The product P sealed with the resin is carried out, and the lead frame LF and the tablet T are carried in by the lead frame carrying mechanism 5 and the tablet carrying mechanism 6.

Next, the operation of the above configuration will be described. First, the outline of the entire operation will be described. The lead frame LF is transferred from the lead frame stock section 1 to the transfer molding machines 3A, 3B by the lead frame transfer mechanism 5, and the tablet T from the tablet stock section 2 is transferred by the tablet transfer mechanism 6 to the transfer molding machines 3A, 3B.
Be transported to.

In the lead frame transfer mechanism 5, the lead frames LF are picked up one by one from the tablet stock section 2 by the frame pusher 51 and the belt conveyor 52 to pick up the products P on the feed 2B. Then, this product P is transferred from the hand mechanism 92 to the gate break mechanism 8. This transfer is performed in the off-road tray mechanism 81 of the gate break mechanism 8 with respect to the cull receiver 815 and the frame receiver 816 at the limit position in the negative X direction.
Then, the cull receiver 815 and the frame receiver 816 move to the limit position in the positive X direction and then rise. As a result, the product P and the resin R at the cull and runner portions are cull receiver 815, frame receiver 816, and gate break plate 82.
And the resin R of the runner portion are cut off at the gate portion.

Next, the cull receiver 815 and the frame receiver
Although 816 descends, the product P and the resin R in the cull and runner portions are adsorbed and remain on the gate break plate unit 82. Then, after the cull receiver 815 and the frame receiver 816 return in the negative X direction, the resin R in the cull and runner portions first falls into a storage box (not shown) and is discharged. After that, the storage tray 7111 of the transport tray mechanism 71 moves below the gate break plate unit 82 and receives the product P from this. Then, the storage tray 7111 returns to the positive Y direction, and the product transfer mechanism 72 and the product storage mechanism 43 store the product P in the product stock section 4.

Although the above steps are repeated, the molding of the resin sealing portion S is alternately performed by the two transfer molding machines 3A and 3B. That is, these transfer molding machines 3
The periods of operation of A and 3B are offset from each other by half. On the other hand, the operation cycle of the other mechanisms 5, 6, 7, 8, 9 shared by the two transfer molding machines 3A and 3B is half the operation cycle of the transfer molding machines 3A and 3B. In this way, while molding the resin-sealed portion S by one of the molding machines 3A and 3B, the product P that is resin-sealed by the other molding machine 3B and 3A is carried out, and then the leads to be resin-sealed. The frame LF and the tablet T are carried in. Therefore, individual transfer molding machines 3A, 3B
Even if the operation cycle of 1 cannot be shortened due to the cure time, the operating efficiency of the entire resin sealing device can be doubled. Moreover, since the stock parts 1, 2 and 4 and the respective mechanisms 5, 6, 7, 8 and 9 other than the transfer molding machines 3A and 3B are shared, the entire resin sealing device can be made compact and an increase in cost can be suppressed.

Since there are two transfer molding machines 3A and 3B, even if one of them fails,
Resin sealing can be performed using only the other.

Furthermore, in the lead frame transfer mechanism 5 and the tablet transfer mechanism 6, the stock parts 1 and 2 to the alignment tables 533 and 644 and the common transfer mechanism from the alignment tables 533 and 644 to the transfer molding machines 3A and 3B. 9 and 9 are configured separately from each other, the lead frame LF to the alignment tables 533 and 644 can be provided while the transfer molding machines 3A and 3B are being carried in and out by the common transfer mechanism 9.
The tablets T can be aligned. Since this alignment takes time, the operation cycle of the entire resin sealing device can be shortened and the efficiency can be further improved by separating the transport mechanisms 5 and 6 from each other. On the other hand, the common transfer mechanism 9 for loading and unloading the transfer molding machines 3A and 3B, which does not take much time, is shared by the lead frame transfer mechanism 5, the tablet transfer mechanism 6 and the product transfer mechanism 7. The whole can be made more compact.

Next, details of the operation of each part will be described. In the lead frame stock unit 1, a supply magazine 10 in which a plurality of lead frames LF before resin sealing are packed is loaded between corresponding magazine holders 111 on the magazine support base 11. Further, the supply magazine 10 that has been emptied after the supply of the lead frame LF is removed from the magazine support base 11. These loading and unloading are done manually.

In the lead frame stock section 1, the supply magazine 10 makes a circular motion as indicated by an arrow in FIG. That is, the supply magazine 10 is the lower magazine support base.
1 in the negative X direction by the magazine traverse mechanism 13
It moves in steps of pitches, then moves up by the magazine elevating mechanism 15, then in the upper magazine support 12 moves by one pitch in the positive X direction by the magazine traverse mechanism 14, and then descends by the magazine elevating mechanism 16. .

The operation of the magazine lateral feed mechanism 13 will now be described in more detail. First, the magazine elevators 1521 and 1621 of the magazine lifting mechanisms 15 and 16 are located below the magazine support base 11
In this state, the lifting platform 133 rises, the magazine support 11 and the supply magazine 10 on the magazine elevator 1621 are respectively placed on the lifting platform 133, and the corresponding fixed press 1332 and movable press 1341 to go into.
Here, the clamp plate 134 moves in the positive X direction, and each movable presser 1341 and each fixed presser 1332 cause each supply magazine 10 to move.
Hold securely. The lifting platform 133 is such that the lower surface of the supply magazine 10 is the magazine support platform 11 and the magazine elevator 152.
1,1621 Magazine holder 111, 1522, 1623 It rises until it becomes higher. Then, after the horizontal slide 132 moves one pitch in the negative X direction, the elevating table 133 descends, and the clamp plate 134 moves in the negative X direction to move the movable holder 13
The holding of the supply magazine 10 by 41 is released. Lift 13
3 is lowered until the pressers 1332 and 1341 are positioned slightly lower than the magazine support base 11, while the supply magazine 10 mounted on the lift base 133 is transferred onto the magazine support base 11 and the magazine elevator 1521, Enter between the corresponding magazine holders 111 and 1522. Thus, supply magazine
10 is conveyed in one pitch X negative direction. The operation of the upper magazine transfer mechanism 14 is also performed when the magazine elevators 1521 and 1621 are elevated to the height of the upper magazine support base 12 and the transfer is performed in the X direction.
Exactly the same, except in the forward direction.

In the magazine lifting mechanism 15, the magazine elevator 1521 is lifted after the supply magazine 10 is transferred from the magazine support base 11 to the magazine elevator 1521. Then, after the supply magazine 10 is transferred from the magazine elevator 1521 to the magazine support base 12, the magazine elevator 1521 descends again. Meanwhile, the magazine support 12 to the magazine elevator
The lead frame LF is supplied to the conveyor 52 from the supply magazine 20 transferred to 1621.
The lead frames LF are supplied one by one from the bottom with respect to the lead frames LF that are vertically stacked in the supply magazine 10. That is, when one lead frame LF is pulled out from the supply magazine 10, the magazine elevator 16
21 is 1 pitch (lead frame in supply magazine 10
The lead frame LF is pulled out, and this is repeated. Then, when the supply magazine 10 becomes empty, the magazine elevator 1621 on which the supply magazine 10 is mounted descends to the height of the magazine support base 11.

The fraction supply magazine 101 is mounted on the magazine elevator 1622 above the magazine lifting mechanism 16. The fraction supply magazine 101 is used, for example, to supplement the lead frame LF. Ie supply magazine
10 must contain a certain number of leadframes LF, but if the leadframe LF in a certain supply magazine 10 is insufficient, the leadframe LF is supplemented from the fraction supply magazine 101. Also, a fraction supply magazine
101 can also be used to load a dummy lead frame. The dummy lead frame is made of resin for cleaning, and the molds 321A, 321B, 322 of the transfer molding machines 3A, 3B are used.
It is used when cleaning A and 322B, and at the time of cleaning, a dummy lead frame is sent to the belt conveyor 52 instead of the regular lead frame. That is, the cleaning resin is occasionally cleaned during the automatic operation. However, since the product molded by the cleaning resin is not the product P, the dummy lead frame is also distinguished from the product P in order to distinguish it from the product P. Is used.

The frame pusher 51 of the lead frame transport mechanism 5 has a fixed height, and the magazine elevator 1621
One lead frame LF is pushed out in the negative Y direction from the supply magazine 10 mounted on. The one lead frame LF pushed out is placed on the belt conveyor 52, and is sent in the Y negative direction by the belt conveyor 52. At the entrance of the belt conveyor 52, the nip roller 523 located above the nip roller 523 assists the lead frame LF.
Pull out in the negative direction to ensure the delivery of the lead frame LF to the belt conveyor 52. Then, on the belt conveyor 52, the lead frame LF abuts on the stopper 525 and stops.

Further, after the elevating table 544 of the frame transfer mechanism 54 is positioned above the belt conveyor 52 and descends, the left and right frame pickups 545 are closed and the elevating table 544 rises again. As a result, the lead frame LF that hits the stopper 525 and stops is the frame pickup.
It can be lifted on the 545. Then, vertical slide 542
Move in the Y negative direction, the elevator 544 descends, and the lead frame LF held by the frame pickup 545
Is placed on the preheat plate 5332 of the frame alignment stand 533. Then, after the frame pickup 545 is opened, the lift 544 is raised and the vertical slide 542 is returned in the Y positive direction.
The lead frame LF remains on the preheat plate 5332. The frame alignment table 533 slides sideways every time one lead frame LF is transferred by the frame transfer mechanism 54.
It moves in the positive direction along with 532 by one pitch (pitch of preheat plate 53) X. This is repeated four times, and four lead frames LF are placed side by side on the frame alignment table 533. The molds 321A, 321B, 322A, 32
Frame alignment table 53 due to the layout of runners in 2B
The even leadframes LF in 3 must be flipped 180 ° with respect to the odd leadframes LF. Therefore, the even-numbered lead frame LF
Only while the lead frame LF is being held by the frame pickup 545, the rotary table 543 of the frame transfer mechanism 54 rotates 180 ° and the direction of the lead frame LF is reversed.

The frame alignment table 533 on which the four lead frames LF are placed is in the standby state at the limit position in the positive X direction. Meanwhile, the preheat plate 5332 preheats the lead frame LF to about 100 ° C. Note that this preheating is not always necessary.

In the tablet stock section 2, the tablet case 20 in which the tablets T are packed on the case base 223 is provided.
Place and load. This loading is performed through the case replacement opening 211 of the stock portion outer shell 21. In the middle of driving,
After the empty tablet case 20 is taken out through the replacement opening 211, the tablet case 20 filled with the tablets T is loaded. This is manual work.

A total of six tablet cases 20 are loaded in the outer shell 21 of the stock section.
The case 20 intermittently circulates together with the roller chains 2212 and 2222 by the case transport mechanism 22 as shown by the arrow in FIG. When the tablet case 20 approaches the case transfer mechanism 61, the tablet transfer mechanism 61 pulls the tablet case 20 out of the stock portion outer shell 21 to take out the tablet T. And the empty tablet case T
Is returned to the case base 223 in the stock portion outer shell 21 again, and is positioned so as to face the case replacement opening 211 by the next drive of the case transport mechanism 22.

Case transfer mechanism 61 of tablet transport mechanism 6
The horizontal slide 613 moves in the negative X direction and is positioned below the flange 202 of the tablet case 20 on the case base 223, and then the horizontal slide 613 rises together with the elevating base 612 so that the horizontal slide 613 is placed on the horizontal slide 613. The flange 202 is mounted. Then, the horizontal slide 613 returns to the positive X direction, the tablet case 20 is pulled out together, and then the elevating table 612 descends again.

Then, the push-up rods 6221 and 6222 of the tablet pusher 62 ascend, and the 2

4 is located above both push-up rods 6221 and 6222, respectively, but after lifting platform 632 is lowered, chuck arms 6331 and 6341 are closed, and one tablet T protruding upward from tablet case 20 is held respectively. To do. Then,
After the elevating table 632 rises, the vertical slide 631 moves in the negative Y direction and is positioned above the tablet aligning table 644 at the limit position of the tablet table mechanism 64 in the positive Y direction and the positive X direction. Then, as the elevator 632 descends,
Chuck arms 6331 and 6341 open, and tablet alignment table 64
Two tablets T are placed at predetermined positions on the above. After that, the lift 632 rises and the vertical slide 631 returns in the positive Y direction. Note that, while the tablet transfer mechanism 63 is transporting the tablet T, one chuck 634 moves in the positive X direction as necessary. This is because the pitch of the push-up rods 6221 and 6222 arranged in the X direction may be different from the pitch of the tablets T on the tablet alignment table 644 in the X direction. After the transfer of the tablet T, the chuck 634 returns in the negative X direction.

After one tablet T protruding upward from the tablet case 20 is removed by the tablet transfer mechanism 63, the push-up rods 6221 and 6222 are further raised by one pitch (the height of the tablet T). Then, one tablet T protruding by this is transferred to the tablet alignment table 644 by the tablet transfer mechanism 63. This is repeated until the tablet alignment table 644 has two rows in the X direction and Y
A total of eight tablets T, four rows in a row, are aligned. After this alignment is completed, the tablet alignment stand 644 will slide sideways 643.
At the same time, it moves in the negative X direction, is positioned below the high-frequency preheater 65, and is in a standby state. This high frequency preheater
65, the tablet T of the tablet alignment stand 644 is 60
It is preheated to about ℃. The preheating is not always necessary.

Then, the horizontal slide 643 moves in the positive X direction, the vertical slide 642 moves in the negative Y direction, and the tablet T on the tablet alignment table 644 is removed by the common transport mechanism 9, and then the vertical slide is performed. 642 moves in the positive Y direction,
The transfer of the tablet T onto the tablet alignment table 644 is repeated. In the meantime, if the tablet compartment 201 of the tablet case 20 becomes empty,
After the 6221 and 6222 descend and come out of the tablet case 20, the vertical slide 621 of the tablet pusher 62 moves in the X direction or the horizontal slide of the case transfer mechanism 61.
613 moves in the Y direction and pushes up the rods 6221 and 6222.
Is located below the tablet housing 201 in which the tablet T of the tablet case 20 is still packed. The starting positions of the chucks 633, 634 are also the push-up rods 6221,
Move in Y direction according to 6222. Then, the transfer of the tablet T as described above is repeated. Further, when all the tablet storage units 201 of the tablet case 20 are emptied, the elevating table 612 of the case transfer mechanism 61 rises, the horizontal slide 613 moves in the negative X direction, and then the elevating table 612 descends. , Return the tablet case 20 to the case base 223 in the outer shell 21 of the stock section. After that, the horizontal slide 613 returns to the positive X direction, and the case transport mechanism 22 causes the next tablet case 20 to move.
Approaches the case transfer mechanism 61.

Here, the hand mechanism of the common transport mechanism 9 is used.
Operation of the frame chuck 94 and the tablet chuck 95 of 92 will be described. The frame chuck 94 and the tablet chuck 95 do not have their own drive source, and therefore the lead frame alignment table 533 and the tablet alignment table 644
, The lower molds 322A, 322B or the stopper piece 8145 of the gate break mechanism 8 are operated in association with the vertical movement. That is,
The frame chuck 94 is actuated by pushing up the receiving rod 941 by the lead frame alignment table 533, the lower molds 322A, 322B or the stopper pieces 8145, and the receiving rod 95 by the tablet alignment table 644 or the lower molds 322A, 322B.
Tablet chuck 95 by pushing 1 up
Works.

First, the operation of the frame chuck 94 will be described. As shown by the chain line in FIG. 16, when the receiving rod 941 is pushed up, the link wheel 9421 connected thereto via the link arm 9413 rotates 45 ° in the clockwise direction. At this time, because of the relationship between the ratchet wheel 9422 and the ratchet pawl 9425, the ratchet wheel 9422 cannot rotate counterclockwise with respect to the link wheel 9421, so the ratchet wheel 9422 and the intermediate shaft 942 to which it is fixed are Turn 45 ° with 9421. In this way, when the intermediate shaft 942 rotates 45 °, the cam receiving roller 94 of the chuck arm 944 is until then.
If 43 hits the concave portion 9445 of the opening / closing timing cam 9444, the cam receiving roller 9443 changes to the state of hitting the convex portion 9446 of the opening / closing timing cam 9444, and conversely, if the cam receiving roller 9443 hits the convex portion 9446. For example, the cam receiving roller 9443 changes into a state of hitting the concave portion 9445. Then, when the cam receiving roller 9443 hits the concave portion 9445, the hook portion 94 of the pair of chuck arms 944 is
When 41 is brought close to each other and opened, and hits the convex portion 9446, the hook portions 9441 of both chuck arms 944 are separated from each other and are closed. In addition, spring 9435
The ball 9434 pushed by is fitted into the concave portion 9432 of the opening / closing lock cam 9431, which prevents the intermediate shaft 942 from rotating inadvertently, and the cam receiving roller 9443 is projected to the concave portion 9445 or the convex portion of the opening / closing timing cam 9444. The state of hitting the portion 9446 is reliably held, and therefore the chuck arm 944 is also securely held in the open / closed state.

When the pushing up of the receiving rod 941 by the lower molds 322A, 322B and the like is released, the receiving rod 941 is lowered by the spring 9412, and the link wheel 9421 rotates 45 ° counterclockwise. At this time, since the ratchet wheel 9422 can rotate clockwise with respect to the link wheel 9421, the intermediate shaft 942 and the ratchet wheel 9422 held by the ball 9434 and the open / close lock cam 9431 are rotated.
Does not rotate. Therefore, the open / closed state of the chuck arm 944 is not switched. As mentioned above, the chuck arm
The reference numeral 944 indicates that the open state and the closed state are alternately switched every time the receiving rod 941 is pushed up once.

Next, the operation of the tablet chuck 95 will be described. When the receiving rod 951 is in the lowered position, the cam receiving roller 9544 of the chuck arm 954 is in contact with the cam 9530 fixed to the upper shaft 952 at a position separated from the convex portion 9539. In this state, the hook portions 9542 of the pair of chuck arms 954 are close to each other and are closed. On the other hand, when the receiving rod 951 is pushed up, the link arm 9533 rotates in conjunction with this, the link piece 9531 and the upper shaft 952 rotate, and the cam 95
The cam receiving roller 9544 rides on the convex portion 9539 of 30. In this state, the hook portions 9542 of the two chuck arms 954 are separated from each other and opened. Also, when the push-up of the receiving rod 951 by the lower molds 322A, 322B, etc. is released, the receiving rod 951 is lowered by the spring 9512, and the link arm 9533, the link piece 9531, the upper shaft 951
2 and the cam 9530 rotate in the opposite direction, and the cam receiving roller 9544 is disengaged from the convex portion 9539. As a result, the chuck arm 954 is closed by the tension of the spring 9543. As is clear from the above description, the chuck arm 95
The opening of 4 is forcibly performed by pushing up the receiving rod 951, but the closing operation of the chuck arm 954 is not forcible, and if a force exceeding the tension of the spring 9543 is applied thereto, it is not performed.

Returning to the explanation of the transportation of the lead frame LF and the tablet T. The hand mechanism 92 first gets the tablets T aligned on the tablet alignment table 644. At this time, the tablet alignment table 644 is placed on the high-frequency preheater 65.
From the stand-by state, which is positioned below, the horizontal slide 643 is moved in the positive X direction and the vertical slide 642 is moved in the negative Y direction. At this point, the tablet alignment table 644 rises, and the receiving rod 951 of the hand mechanism 92 is
Push up. Note that the receiving rod 941 is not pushed up but remains lowered due to the setting of the unevenness on the upper surface of the tablet alignment table 644. Then, the tablet alignment table 644 descends and the receiving rod 951 descends again. Receiving rod 95
With the pushing up of 1, a total of 8 pairs of chuck arms 954 of the tablet chuck 95 are opened, and the hooks 9542 sandwich the tablets T so as to bite into the softened tablet T. Then, as the receiving rod 951 descends, the chuck arm 954 closes,
Hold the tablet T securely.

Next, the hand mechanism 92 goes to pick up the lead frame LF aligned on the lead frame alignment table 533. At this time, first, the horizontal slide 912 moves in the negative X direction to position the hand mechanism 92 above the lead frame alignment table 533 in the standby state, and then the lead frame alignment table 533 rises. Along with this, the hook portions 9441 of the four pairs of chuck arms 944 with the frame chuck 94 open.
Passes beside each lead frame LF and reaches below. In addition, the lead frame alignment table 533 allows the receiving rod
As the 941 is pushed up, the chuck arm 944 closes. Therefore, after that, the lead frame alignment table 53
When 3 descends again, the lead frame LF will
It is placed on the 9441 and held by the chuck arm 944. A frame retainer 9553, which is independent of the chuck arm 944, retains the lead frame LF from above and prevents the lead frame LF from being distorted. It should be noted that due to the unevenness of the upper surface of the lead frame alignment table 533, even when the lead frame alignment table 533 is raised, the receiving rod 951 is not pushed up and remains down.

If the lead frame LF is held by the frame chuck 94, the lead frame LF pushes up the probe 981 of the detection mechanism 98 to detect that the lead frame LF is held. On the other hand, if the probe 981 remains lowered, it is detected that the lead frame LF is not held, and the device is stopped as if there is an abnormality.

Next, the hand mechanism 92 includes the upper molds 321A, 32A in the mold open state of one of the transfer molding machines 3A, 3B.
Enter between 1B and lower molds 322A and 322B. The hand mechanism 92 moves in the negative Y direction together with the vertical slide 913 from the position above the lead frame alignment table 533 when entering the one transfer molding machine 3A, and along with the horizontal slide 912 when entering the other transfer molding machine 3B. After moving in the positive X direction, it moves in the negative Y direction. In the transfer molding machines 3A and 3B, the hydraulic cylinder 315
By driving A and 315B, lower molds 322A and 322B rise together with lower platens 314A and 314B.
The receiving rods 941 and 951 of the hand mechanism 92 are pushed up by the 322B. With this pushing up, the frame chuck
94 and tablet chuck 95 chuck arm 944,
954 open respectively. As a result, the lead frame LF and the tablet T are moved from the chucks 94, 95 to the lower molds 322A, 32.
It will be transferred to 2B. The chuck arm 954
When the tablet pusher 96 is open, the air cylinder 963 of the tablet pusher 96 drives the elevator table 961 to descend, and the convex portions 964 of the tablet pusher 96 move the tablets T to the pots of the lower molds 322A and 322B.
Forcibly push into 323A, 323B. As a result, defective loading of the tablet T due to catching or the like can be prevented, and this loading can be ensured. After that, the lifting platform 961 rises again. Then, after the lower molds 322A and 322B descend once,
The hand mechanism 92 moves in the positive Y direction, leaving the lead frame LF and the tablet T on the lower molds 322A and 322B, and the upper mold 321.
It comes out between A, 321B and lower molds 322A, 322B.

Even in this state, when it is detected that the probe 981 of the detection mechanism 98 of the hand mechanism 92 is still raised and the lead frame LF is still held by the frame chuck 94, the lower molds 322A and 322B are detected. To leadframe
The equipment stops as if the transfer of LF was not successful.

Thereafter, the lower molds 322A and 322B are raised again,
The mold is closed. In this state, the mold cavity is filled with the epoxy resin in the pots 323A and 323B through the cull, runner and gate by a plunger (not shown).
The resin sealing portion S is molded with respect to the lead frame LF.
After that, the mold is opened after the curing time, and at this time, the product P having the resin sealing portion S molded on the lead frame LF and the resin R of the cull and runner portions are first the upper mold 32.
It leaves 1A and 321B and remains on the lower molds 322A and 322B.

One of the transfer molding machines 3A, 3B
While the molding is being performed in this way, in the other transfer molding machines 3B and 3A, the hand mechanism 92 causes the product P
And the resin R in the cull and runner portions are carried out, and the next lead frame LF and tablet T are carried in.

When the product P and the resin R in the cull and runner portions are carried out from the transfer molding machines 3A, 3B, the hand mechanism 92 moves in the X direction to move from the position facing the other transfer molding machine 3B, 3A to the other side. After moving to a position facing the transfer molding machines 3A, 3B, the hand mechanism 92 moves in the Y negative direction, and the upper molds 321A, 321B and the lower molds 322A, 322B of the transfer molding machines 3A, 3B are moved. Enter Then, the lower molds 322A and 322B move up, and along with that, the hook portion 9441 of the chuck arm 944 of the frame chuck 94 opens next to each lead frame LF on the lower molds 322A and 322B and reaches below. . Also, the lower mold 32
2A and 322B push up the receiving rods 941 and 951 to close the chuck arm 944. Therefore, after that, when the lower molds 322A and 322B descend again, the lead frame LF is held by the chuck arm 944.
At the same time, by driving the air cylinder 972 of the cull suction mechanism 97, the lift table 971 is lowered and air is sucked into the vacuum pipe 973, and the resin R of the cull and runner portions is sucked into the suction port 9731. . After that, the hand mechanism 92 moves in the positive Y direction.

As described above, the frame chuck 94 holds the unsealed portion of the lead frame LF of the product P, and the cull suction mechanism 97 sucks and holds the resin R in the cull and runner portions. Lower mold 322A with resin sealing portion S and resin R of cull and runner portions,
Release from the 322B is surely performed.

In the transfer molding machines 3A and 3B, the common transfer mechanism 9 is used to transfer the product P from the top of the lower molds 322A and 322B.
And the resin R of the cull and runner parts are carried out,
Cleaners 33A and 33B clean the lower molds 322A and 322B.
That is, the cleaners 33A and 33B vibrate and reciprocate on the lower molds 322A and 322B in the X direction. In the meantime, by blowing and sucking air from the nozzles 332A and 332B of the cleaners 33A and 33B and smashing with the brushes 333A and 333B, resin residue and the like are removed from the lower molds 322A and 322B. Then, the next lead frame LF and tablet T are carried in.

Then, the hand mechanism 92 conveys the product P taken out from the transfer molding machines 3A and 3B and the resin R of the cull and runner portions to the gate break mechanism 8. The transfer to the gate break mechanism 8 is performed behind the transfer molding machine 3B. Therefore, in the case of unloading from the transfer molding machine 3A, the hand mechanism 92 is used.
Moves in the positive Y direction and then in the positive X direction.
Here, the lift 813 of the off-road tray mechanism 81 rises, and with this rise, the stopper rod 8145 pushes up the receiving rod 941 of the hand mechanism 8. In addition, by setting the unevenness on the upper surface of the stopper piece 8145, the receiving rod 951
Is not pushed up and remains down. As the receiving rod 941 is pushed up, the chuck arm 944 of the frame chuck 94 opens. Along with this, the vacuum pipe
The adsorption by 973 is released. As a result, the product P and the resin R of the cull and runner portions are transferred onto the frame receiver 816 and the cull receiver 815, respectively.
The hand mechanism 92 then goes to the tablet alignment table 644 to pick up the tablet T.

Then, after the lift 813 is lowered, the horizontal slide 812 is moved in the positive X direction to a position below the gate break plate unit 82. At this point, the lift 813 rises.
With this rise, as shown in FIG. 17A, first, the gate break plate unit 82 is attached to the lead frame LF portion of the product P placed on the frame receiver 816 of the off-road tray mechanism 81, which is not resin-sealed. Frame holder 823
, 824 hits from the top, and vacuum pipe is placed on the resin R on the cull and runner parts on the cull receiver 815.
825 hits from above. As shown in FIG. 17 (b),
Further, as the lift 813 rises, the frame retainers 823 and 824 are pushed up against the springs 8232 and 8242, but also push down the frame receiver 816 against the spring 8161. However, since the resin R in the cull and runner portions rises integrally with the tray base 814, the inner frame retainer 823, which is closer to the resin R in the cull and runner portions, rises more than the outer frame retainer 824. . As a result, the frame receiver 816 is inclined so that the outside is lowered, and the resin sealing portion S of the product P is bent with respect to the resin R in the runner portion. As a result, the resin R at the runner portion and the resin sealing portion S are cut at the gate. The mold of this embodiment is a lower gate type. That is, the runner and the gate are located below the lead frame LF with respect to the mold cavity for molding the resin sealing portion S. Therefore, the bending direction at the time of the gate break is as illustrated.

After this cutting, the vacuum pipes 825 and 826
The air is sucked in, and the resin R of the cull and runner portions is adsorbed on the lower end of the vacuum pipe 825, and the resin sealing portion S of the product P is adsorbed on the lower end of the vacuum pipe 826. Along with this, the lifting platform 813 descends, but since the resin R and the product P in the cull and runner portions are adsorbed by the vacuum pipes 825 and 826, they stop at the gate break plate unit 82. Then slide sideways
812 returns in the negative X direction. Next, the adsorption of the cull and runner portions on the resin R is first released, and the resin R is dropped and discharged into a storage box (not shown).

Next, the vertical slide 711 of the product transfer mechanism 7 moves below the gate break plate unit 82 that adsorbs and holds the product P. Where vacuum pipe 826
The adsorption by is released, and a total of four products P are vertically slid 71
1 on each storage tray 7111. Then, the vertical slide 711 returns in the positive Y direction. Here, the product transfer mechanism 72
The chuck 723 descends, the chuck arm 7231 is closed, and then the chuck 723 rises again. As a result, the product P on the storage tray 711 is held by the chuck 723. Then, the chuck 723 moves in the positive Y direction together with the vertical slide 721 and, if necessary, the horizontal slide 72.
It moves in the X direction together with 2, and is located above one storage magazine 42 mounted on the product stock section 4. In this storage magazine 42, the storage lifter of the product storage mechanism 43
When the chuck 723 is contained and the chuck 723 is lowered, the product P held therein is placed on the storage lifter 433 or the product P already stacked on the storage lifter 433. Then, after the chuck arm 7231 is opened, the chuck
The 723 moves up leaving the product P and returns to the upper side of the storage tray 711 by the movement of the slides 721 and 722. By the way, the product P that has been inverted by 180 ° when transferred to the frame alignment table 533 is returned to its original direction by the chuck 723 rotating horizontally by 180 ° while being conveyed by the product transfer mechanism 72. Will be returned. That is, in the storage magazine 42,
All products P will be stored in a fixed orientation.

As described above, the product transfer mechanism 72 sequentially transfers the products P placed on the four storage trays 7111 of the transfer tray mechanism 71 to the product stock 4 one by one.
After all the storage trays 7111 have been emptied, the product P is again supplied from the gate break mechanism 8 to these storage trays 7111. Then, the transfer by the product transfer mechanism 72 is repeated. On the other hand, the storage lifter 433 of the product storage mechanism 43
Every time one product P is added to the top, the pitch is lowered by one pitch (the height of the product P). In this way, a plurality of products P are stored in one storage magazine 42 in a vertically overlapping manner. Further, after a predetermined number of products P are stored in one storage magazine 42, the storage lifter 433 descends and comes out of the magazine table 41. Then, the storage lifter 433 is X together with the side slide 432.
After moving in the direction and being located below the still empty storage magazine 42, it rises into this storage magazine 42. Initially, the cradle 4331 at the top of the storage lifter 433 is the storage magazine 42.
Located at the top opening of the. Thus, the products P are sequentially stored in the plurality of storage magazines 42.

Then, the storage magazine 42 in which the products P have been stored is taken out manually, and instead, an empty storage magazine 42 is mounted on the magazine base 41.

The fraction storage magazine 421 placed at one end of the magazine base 41 stores, for example, a dummy lead frame resin-sealed with a cleaning resin.
