Description

The present invention includes a work loading device for loading a work before molding and a mold resin into a mold mold, a resin unloading device for carrying out a workpiece after molding and an unnecessary resin mold, a mold mold, and any of these. Regarding the provided resin molding device.

When the above-mentioned work is carried into a mold and the outer peripheral edge is clamped for transfer molding, the resin path (including the runner gate, overflow gate, air vent, etc.) intersects the work end, so that the mold resin comes from the end face. It is easy to leak, and resin burrs may occur on the surface and sides of the work. For this reason, a technique has been proposed in which a pot block provided with a pot is provided so as to be able to move up and down, the work end is pressed by the pot block, and a resin passage (bridge gate: bridged portion) is formed on the block surface.

For example, in order to prevent the mold resin from wrapping around the work end face, it is necessary to align the work end face with the opposite mold end face to eliminate the generation of gaps as much as possible. For this reason, a technique has been proposed in which one end surface of a rectangular strip substrate which is a work is pushed by a push block to abutte the opposite end face against the end face of a pot insert and align them (Patent Document 1: Japanese Patent Application Laid-Open No. (See 2015-51557).
Further, a mold mold provided with a reciprocating mechanism for reciprocating the semiconductor substrate receiving portion of the mold mold on both sides with respect to the gate block position by an air cylinder has also been proposed. (Refer to Patent Document 2: Japanese Patent Application Laid-Open No. 2015-79864).

As shown in FIG. 7, the pot block 3a is always urged by the coil spring 3c together with the pot 3e in a direction away from the clamp surface of the lower mold 3, and is made into the work set recess 3g by the work loading device (loader 4) described later. In the positioned and placed work W, the pot block 3a is pushed down by the upper mold 2 by closing the mold, straddling the work end and clamped with the lower mold insert 3b.

(Loader mechanism)
Next, an example of a loader 4 (work loading device) for loading the work W and the mold resin R1 into the mold mold 1 will be described with reference to FIGS. 1 and 6.
As shown in FIG. 1, the loader 4 carries the work W and the mold resin R1 into the mold 1 (lower mold 3) which has been opened. The loader body 4a is provided so as to move in the XY directions in the horizontal plane and to be able to move up and down with respect to the lower die clamp surface of the lower die 3. The work W is positioned with respect to the pot block 3a provided on the lower mold 3 and the work set recesses 3g arranged on both sides thereof.

As shown in FIG. 6, the loader main body 4a is provided with a resin charging portion 4b for charging the mold resin R1 (for example, tablet resin) into the pot 3e of the pot block 3a while holding the mold resin R1 (for example, tablet resin). The resin charging portion 4b stores and conveys the mold resin R1 in a tubular container, and the shutter 4c provided at the bottom of the container opens and closes to charge the mold resin R1 into the pot 3e. Further, in FIG. 1, a pair of work holding portions 4d that can be contacted and separated while holding the work W (for example, a rectangular substrate) are provided on both sides of the resin charging portion 4b. The pair of work holding portions 4d is slidably assembled with the loader hand 4f via the slide mechanism 4e with respect to the loader main body 4a. As the slide mechanism 4e, for example, a rodless cylinder is used, and the pair of loader hands 4f can be simultaneously moved in the left-right direction of FIG. 1 in the approaching direction and the separating direction. Further, each loader hand 4f is provided with a pair of open / close claws 4g that can be opened and closed to hold both sides of the work W (for example, a rectangular substrate) in the width direction. The opening / closing claw 4g is opened / closed via, for example, a link mechanism that opens / closes by driving a cylinder (not shown).

As shown in FIG. 1, the work holding portion 4d is brought close to each other until the position where the pot block 3a in the raised position and the work set recess 3g overlap each other in a plan view while holding the work W, and the work set recess 3g is used. It is designed to be handed over to a plurality of protruding support pins 3i. In this way, the loader main body 4a is inserted into the mold opening mold 1, the mold resin R1 is charged into the pot 3e of the pot block 3a from the resin charging portion 4b, and the work W before molding is held. The work holding portion 4d of the above is brought close to each other to a position where the pot block 3a in the raised position and the work set recess 3g overlap each other in a plan view, and is delivered to the lower die 3. It is preferable that the resin charging section 4b throws the mold resin R1 into the pot 3e when the work W held by the pair of work holding sections 4d is delivered to the lower mold 3.

As a result, the loader 4 supplies the mold resin R1 to the pot 3e of the pot block 3a at the timing of carrying in the work W of the work set recess 3g, so that the work carrying-in work can be smoothly realized and the mold closing operation proceeds. The work W positioned so as to be can be sandwiched by the cross-linked portion 3d of the pot block 3a.

(Unloader mechanism)
Next, an example of an unloader 5 (work unloading device) for carrying out the work W (molded product) and the unnecessary resin R2 after molding into the mold mold 1 will be described with reference to FIG.
As shown in FIG. 13, the unloader 5 carries out the molded work W (molded product) and the unnecessary resin R2 from the mold open mold 1 (lower mold 3).
When the mold 1 is opened after the resin molding, the work W after molding is supported by the support pin 3i protruding from the work set recess 3g of the mold mold 1, and the pot block 3a is separated from the lower mold clamp surface. The supported unnecessary resin R2 is separated. (The operation after mold molding will be described later.) In this state, the unloader main body 5a enters the mold mold 1 and carries out the work W and the unnecessary resin R2 (molded product carrunner). The unloader main body 5a is provided with a cal holding block 5b (unnecessary resin collecting unit) for collecting unnecessary resin R2 from the pot block 3a while holding unnecessary resin R2. The cal holding block 5b is suspended and supported by a coil spring 5c with respect to the unloader main body 5a. The cal holding block 5b is pressed against the molded product carrunner R2 by a suction pad 5b1 provided at the lower end portion to suck and hold the calrunner. In this embodiment, the unnecessary resin R2 is held by the suction pad 5b1, but it is not always necessary to use the suction pad 5b1, and the cal holding block 5b holds the unnecessary resin R2 by the opening / closing claw (not shown). You can do it.

Further, on both sides of the cal holding block 5b, a pair of work collecting portions 5d that can be contacted and separated while holding the molded work W (molded product) are provided. The pair of work collecting units 5d are slidably assembled with the unloader hand 5f via the slide mechanism 5e with respect to the unloader main body 5a. As the slide mechanism 5e, for example, a rodless cylinder is used, and the pair of unloader hands 5f can be simultaneously moved in the left-right direction of FIG. 13 in the approaching direction and the separating direction. Further, each unloader hand 5f is provided with openable / closable opening / closing claws 5g for holding both sides of the work W (for example, a rectangular substrate) in the width direction. The opening / closing claw 5g is opened / closed via, for example, a link mechanism that opens / closes by driving a cylinder (not shown).

The cal holding block 5b holds the unnecessary resin R2, the work collecting part 5d holds the work W after molding from the work set recess 3g of the lower mold 3, and the pair of work collecting parts 5d holds the work W and the pot block 3a. The work W after molding is carried out so as to be separated from each other to a position where it does not interfere with.
In this way, the unloader main body 5a is inserted into the mold opening mold 1, the cal holding block 5b sucks and holds the unnecessary resin R2 supported by the pot block 3a, and the pair of workpiece collecting portions 5d mold. The work W after molding is held and separated from each other by the slide mechanism 5e to a position where it does not interfere with the pot block 3a, and the work W after molding is carried out. As a result, the work collecting unit 5d carries out the molded work W from the work set recess 3g while holding the molded product so as not to interfere with the pot block 3a, so that the configuration of the mold mold 1 can be simplified. ..

(Loader operation)
Here, an example of the molding operation of the resin molding apparatus will be described together with the operation of loading and unloading the workpiece into the mold. First, the work loading operation by the loader 4 will be described with reference to FIGS. 1 to 5.
In FIG. 1, the work W (rectangular substrate) and the mold resin R1 are carried into the lower mold 3 which has been opened. In the lower mold 3, the pot block 3a and the pot 3e are urged by the coil spring 3c and are in a raised position from the lower mold clamp surface (upper surface of the lower mold insert 3b), and the support pin 3i protrudes from the work set recess 3g. ..
The loader 4 holds the mold resin R1 in the resin charging section 4b, and the loader hand 4f holds the pair of workpiece holding sections 4d at positions separated from the resin loading section 4b by the slide mechanism 4e (positions opened to the left and right). Then, the opening / closing claw 4g enters the mold 1 while gripping both sides of the work W (rectangular substrate) in the lateral direction.

In FIG. 2, the loader 4 is lowered and the work W held by the loader hand 4f is placed on a plurality of support pins 3i protruding above the work set recess 3g. The opening / closing claw 4g is in a state of holding the work W while being closed.

In FIG. 3, the slide mechanism 4e is operated to slide the pair of loader hands 4f in the direction of approaching the resin charging portion 4b. At this time, since the opening / closing claw 4g is located between the cross-linked portions 3d in a plan view, it does not interfere with the pot block 3a, and the height of the upper surface of the work W is lower than the lower surface of the cross-linked portion 3d. Therefore, the tip of the work W slides so as to slip under the cross-linked portion 3d. Further, since the resin charging portion 4b is located directly above the pot block 3a, the shutter 4c is opened and the mold resin R1 (tablet resin) is charged into the pot 3e.

In FIG. 4, the opening / closing claw 4g of the loader hand 4f is opened to deliver the work W (rectangular substrate) onto the support pin 3i. At this time, the pilot hole Wh of the work W and the pilot pin 3j of the lower mold 3 are aligned. Since the opening / closing claw 4g is arranged in the escape space S (see FIG. 12B) of the pot block 3a in a plan view, it does not interfere with the cross-linking portion 3d.
In FIG. 5, when the work W is delivered to the lower mold 3, the loader main body 4a rises and retracts from the mold mold 1. Further, since the work W and the mold resin R1 have been carried into the mold mold 1, the mold closing operation of the mold mold 1 proceeds. That is, since the lower mold 3 starts to rise, the support pin 3i is relatively lowered, the pilot pin 3j is fitted into the pilot hole Wh, the position of the work W is determined in the work set recess 3g, and the work W is placed. ..
Further, since air suction is started in advance from the suction hole 3h provided in the work set recess 3g or air is sucked after the work is placed, the work W is positioned and fixed in the work set recess 3g.

In this way, the work W carried in by the loader 4 is positioned in the work set recess 3g of the lower mold 3 of the mold 1 opened, and the pot block 3a is pushed down to the upper mold 2 by closing the mold. Since it is clamped with the mold insert 3b, the configuration on the mold side is simplified, the mold cost is low, the mold resin R1 can be avoided from wrapping around to the work end face, and malfunction in the mold is less likely to occur. Maintenance is also easy.

(Mold mold operation)
Next, the resin molding operation by the mold mold 1 will be described with reference to FIGS. 7 to 11. FIG. 7 shows a state in which the work W is set in the work set recess 3g of the lower mold 3 and the tablet resin R is loaded in the pot 3e. The pot block 3a and the pot 3e are urged by the coil spring 3c and are in the ascending position. Further, the release film F is attracted and held on the clamp surface of the upper mold 2, and the auxiliary pin 2d protrudes from the upper mold clamp surface so as to push down the release film F.

When the mold closing operation proceeds and the upper mold 2 abuts against the pot block 3a, the pot block 3a and the pot 3e are pushed down against the urging of the coil spring 3c. Then, as shown in FIG. 8, when the lower mold 3 and the upper mold 2 are closed, the pot block 3a and the pot 3e are in a state of being clamped to the upper mold 2 and the lower mold 3. At this time, the cross-linked portion 3d provided in the pot block 3a straddles the outer peripheral edge portion of the work W positioned in the work set recess 3g and presses the work upper surface (board surface). As a result, there are a plurality of resin paths communicating with the upper die cavity recess 2a between the upper die cal 2b and the upper die runner gate 2c and the upper end surface (upper surface of the cross-linking portion 3d) of the pot block 3a (5 places in FIG. 12). Is formed in. Further, the auxiliary pin 2d (see FIG. 7) protruding from the upper die 2 abuts on the substrate surface of the opposing work W and is pushed back.

The mold resin R1 filled in the upper die cavity recess 2a is heat-cured (cure).

In FIG. 10, the mold mold 1 is opened. At this time, as the lower mold 3 descends while the work W is attracted and held in the work set recess 3g, the pot block 3a and the pot 3e urged by the coil spring 3c rise relatively. As a result, the package portion PK (resin sealing portion) of the work W (molded product) after molding and the unnecessary resin R2 (molded product carrunner) formed on the pot block 3a are gate-breaked. Further, the auxiliary pin 2d protrudes from the upper mold 2 and presses the substrate surface of the work W, so that the package portion PK and the upper mold cavity recess 2a covered with the release film F are easily released from the mold.

Next, in FIG. 11, as the mold opening progresses, the support pin 3i protrudes from the work set recess 3g, so that the work W is pushed up from the work set recess 3g. As a result, the work W is in a state where the pilot pin 3j is pulled out from the pilot hole Wh. The air suction of the suction hole 3h provided in the work set recess 3g may be continued, or may be stopped when the mold is opened.

(Unloader operation)
Finally, the work unloading operation by the unloader 5 will be described with reference to FIGS. 13 to 16. In FIG. 13, the unloader 5 enters the mold 1 that has been opened. In the lower mold 3, the pot block 3a and the pot 3e are urged by the coil spring 3c and are in a raised position from the lower mold clamp surface (upper surface of the lower mold insert 3b), and the support pin 3i protrudes from the work set recess 3g. .. Therefore, the work W (molded product) and the unnecessary resin R2 (molded product carrunner) after molding are in a separated state. In the unloader 5, the unloader hand 5f is held at a position where the pair of workpiece collecting portions 5d are close to the cal holding block 5b (position according to the center) by the slide mechanism 5e, and the opening / closing claw 5g is opened and molded. Enter mold 1.

In FIG. 14, the unloader 5 descends and the opening / closing claws 5g of the unloader hand 5f enter both sides of the work W supported by the support pins 3i. At this time, since the opening / closing claw 5g is located between the cross-linked portions 3d, it does not interfere with the pot block 3a. Then, the work W is gripped by closing the opening / closing claw 5g. Further, since the suction pad 5b1 is pressed against the unnecessary resin R2 (molded product carrunner) in the cal holding block 5b, the unnecessary resin R2 is sucked and held.

In FIG. 15, the slide mechanism 5e is operated to slide the pair of unloader hands 5f in the directions (both left and right sides) away from the cal holding block 5b.
In FIG. 16, the unloader 5 raises the unloader main body 5a and retracts from the mold 1 while holding the molded work W (molded product) and unnecessary resin R2 (molded product carrunner).
The unloader 5 delivers the molded product to the molded product storage unit and collects the unnecessary resin R2 in the scrap box to complete a series of resin molding operations.

The resin molding device 6 provided with the mold mold 1, the loader 4, and the unloader 5 described above can be applied to, for example, the device shown in the plan layout diagram of FIG. 25.
