Description

The present invention relates to a resin sealing device equipped with a digitizer and a cleaning method thereof.

A resin sealing device including a degator is known (for example, see Patent Document 1). The degator uses degate hands to sandwich the sealed product placed on the degate pallet and separates unnecessary resin such as cull from the sealed product. The degate pallet reciprocates directly below the degate hand that moves up and down, receives sealed products from the unloader hand, and delivers sealed products from which unnecessary resin has been removed to the molded product storage mechanism. .

Japanese Patent Application Publication No. 2012-43839

Dust such as resin debris may adhere to the underside of the degate hand due to static electricity. If a sealed product is sandwiched between the degate pallet and the degate hand with dust attached to the lower surface of the degate hand, problems such as dents may occur on the surface of the sealed product. In such cases, the resin sealing device is stopped and the operator cleans the degate hand. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a resin sealing device and a cleaning method thereof, which can reduce the burden on the operator and reduce the number of parts.

The resin sealing device according to one aspect of the present invention can sandwich the resin-sealed product between a degate pallet and a degate hand that moves up and down with respect to the degate pallet. The device includes a degator that separates unnecessary resin from the molded product, and an unloader that takes out the molded product from the resin mold and conveys it to the degator. The unloader has an unloader body that is movable in a section including a first standby position where the sealed product is carried out from the resin molding mold and a second standby position where the sealed product is carried into the degator, and an unloader body that can move forward and backward from the unloader body. The unloader hand enters into the resin-sealed mold from the unloader body that has moved to the first standby position, holds the resin-sealed product, and retreats to the unloader body. The degate pallet and the degate hand are characterized by providing an interval that allows the unloader hand to move back and forth between the degate pallet and the degate hand from the unloader body that has moved to the second standby position.

According to this aspect, the unloader hand can enter between the degate pallet and the degate hand. Therefore, for example, by adding a cleaning member to the unloader hand, or by using the existing cleaning member in the unloader hand for cleaning the digitizer, dust attached to the digit pallet and the digit hand can be removed. In this case, the cleaning member provided in front of the molded product storage mechanism for cleaning the degate pallet can be omitted, so the number of parts can be reduced. Moreover, according to this aspect, the range in which the unloader can move is expanded. Therefore, for example, by replacing part of the reciprocating movement of the degate pallet with the forward and backward movement of the unloader hand, the distance over which the degate pallet reciprocates can be shortened. In this case, the area occupied by the degate pallet can be reduced, and the degree of freedom in designing the layout of the resin sealing device can be improved.

In the above aspect, the unloader hand is provided at the tip of the unloader hand, and is capable of removing dust attached to at least one of the degate pallet and the degate hand when the unloader hand enters between the degate pallet and the degate hand. The unloader may include a cleaning member (cleaner).

According to this aspect, dust attached to the degate hand and the degate pallet can be removed by the cleaning member provided at the tip of the unloader hand.

In the above aspect, the cleaning member may include a lower cleaning member movable below the lower end of the unloader hand, and an upper cleaning member movable above the upper end of the unloader hand.

According to this aspect, when cleaning the degator, the cleaning member comes into contact with the degate pallet and the degate hand, and when not cleaning the degator, the cleaning member is prevented from coming into contact with the degate pallet and the degate hand. The height of the lower cleaning member and upper cleaning member can be adjusted.

In the above aspect, the degate pallet is movable at a height that is lower than the lower end of the unloader hand and slides into contact with the lower cleaning member moved downward from the unloader hand, and the degate hand is lower than the lower end of the unloader hand. It may be movable at a height that is higher than the upper end and slides into contact with the upper cleaning member that has been moved upward from the unloader hand.

According to this aspect, the degate pallet and the degate hand can be moved to a height where the unloader hand does not collide with them. Even if there is a gap between the degate pallet or the degate hand and the unloader hand, the lower cleaning member can be brought into sliding contact with the degate pallet, and the upper cleaning member can be brought into sliding contact with the degate hand.

In the above aspect, the lower cleaning member and the upper cleaning member are brushes that extend in a direction intersecting the advancing and retreating direction of the unloader hand, and the cleaning member is provided along at least one of the lower cleaning member and the upper cleaning member. It may also have a dust collection port that can suck dust.

According to this aspect, the dust adhering to the degate pallet and the degate hand can be efficiently removed by the combination of the brush that removes dust and the dust collection port that sucks the dust removed by the brush. Since dust is sucked by the dust collection port, it is possible to prevent dust from scattering at the installation location of the resin sealing device.

In the above aspect, the cleaning member may also have the function of removing dust attached to the resin-sealed mold surface of the resin-sealed mold when the unloader hand enters the resin-sealed mold. .

According to this aspect, the degate pallet and the degate hand can be cleaned by reusing the cleaning member that is already installed in the unloader hand and that cleans the surface of the resin-sealed mold. Since there is no need to add a cleaning member dedicated to the digitizer, the manufacturing cost of the resin sealing device can be reduced.

In the above aspect, the resin sealing mold is composed of a lower mold and an upper mold that face each other vertically, and the degate pallet has a height such that the height of the upper surface of the degate pallet is approximately the same as the surface of the lower mold. The degate hand may be movable at a height such that the height of the lower surface of the degate hand is substantially the same as the surface of the upper mold.

According to this aspect, when cleaning the degate pallet and the degate hand by reusing the existing cleaning member in the unloader hand, there is no need to change the design of the cleaning member or the unloader hand. It is possible to reduce manufacturing costs and standardize parts.

A cleaning method for a resin sealing device according to one aspect of the present invention includes sandwiching a resin-sealed product between a degate pallet and a degate hand that moves up and down with respect to the degate pallet. The present invention includes a degator that separates unnecessary resin from the molded product, and an unloader that takes out the molded product from the resin mold and conveys it to the degator. The unloader has an unloader body that is movable in a section including a first standby position where the sealed product is carried out from the resin molding mold and a second standby position where the sealed product is carried into the degator, and an unloader body that can move forward and backward from the unloader body. The unloader hand enters the inside of the resin sealing mold from the unloader body that has moved to the first standby position, holds the sealed product and retreats to the unloader body, and the cleaning device provided at the tip of the unloader hand It is equipped with a member. When the unloader hand enters between the degate pallet and the degate hand, the cleaning member removes dust attached to one of the degate pallet and the degate hand, and when the unloader hand retreats to the unloader body, the cleaning member removes dust adhering to the other side of the degate pallet and the degate hand.

According to this aspect, dust attached to the degate pallet and the degate hand can be removed using the cleaning member provided at the tip of the unloader hand. Because the degate pallet and degate hand are cleaned one by one at different times, compared to cleaning the degate pallet and degate hand at the same time, for example, the suction power of the suction pump that sucks dust from the dust collection port is not dispersed. . Powerful suction power allows efficient dust collection.

According to the present invention, it is possible to provide a resin sealing device and its cleaning method that can reduce the burden on an operator and reduce the number of parts.

The height is such that it bends slightly upon contact.

FIG. 3 is an enlarged plan view showing the unloader 9 and the degator 10 shown in FIG. As shown in FIG. 3, the unloader main body 91 has a section including a first standby position X1 where the sealed product W' is carried out from the mold 6 and a second standby position X2 where the sealed product W' is carried into the degator 10. is movable. The unloader hand 92 can enter the unloader body 91 that has moved to the first standby position X1 or the inside of the mold 6, hold the resin-sealed product W', and retreat to the unloader body 91.

The degator 10 described above includes a degate pallet 110 that is movable along the Y-axis direction and a degate hand 120 that is movable along the Z-axis direction. The degate pallet 110 transports the sealed product W' to the unloader 9 or the sealed product storage module 11. The degate pallet 110 receives the sealed products W' from the unloader 9 via the second position Y2 directly below the degate hand 120, and the sealed products W' in the sealed product storage module 11. It moves back and forth between the third position Y3 and the handover.

FIG. 4 is a side view showing an example of the degate pallet 110 and the degate hand 120. The degator 10 sandwiches the sealed product W' between the degate pallet 110 and the degate hand 120, bends the unnecessary resin R cured with a cull 65 (shown in FIG. 2), etc., and separates the unnecessary resin R. . The separated unnecessary resin R is collected in the cull box 130.

In the illustrated example, two sealed products W' are connected via the unnecessary resin R cured by the cull 65. The degate pallet 110 has a first part (left flap) 111 that supports one sealed product W', a second part (connection part) 112 that supports unnecessary resin R, and a second part (connection part) 112 that supports the other sealed product W'.

The degator 10 according to the present embodiment is characterized by providing a distance S between the degate pallet 110 and the degate hand 120 in which the unloader hand 92 can move forward and backward. In the illustrated example, the cylinder 140 of the drive source that drives the delegate hand 120 up and down is made longer, thereby providing a wider interval S than in the conventional machine.

According to this embodiment, since the unloader hand 92 can enter into the degator 10, the unloader hand 92 can be provided with a cleaning member to remove dust attached to the degate pallet 110 and the degate hand 120, for example. The frequency with which the operator cleans the degate hand 120 and the like by stopping the resin sealing device 1 can be reduced, and the burden of doing so can be reduced. The number of parts can be reduced by omitting the cleaning member provided for cleaning the degate pallet in the conventional resin sealing apparatus.

As a cleaning member for removing dust attached to the degate hand 120 etc., the cleaning member 70 for mold cleaning described with reference to FIG. 2 may be used, or a new cleaning member may be added. . When the cleaning member 70 is reused, the degate pallet 110 has a height that is lower than the lower end (for example, the lower surface 92B) of the unloader hand 92 and slides into contact with the lower cleaning member 71 that has been moved downward from the unloader hand 92. You can move horizontally. The degate hand 120 that moves up and down can move vertically to a height that is higher than the upper end (for example, the upper surface 92A) of the unloader hand 92 and slides into contact with the upper cleaning member 72 that has been moved upward from the unloader hand 92. .

The height at which the degate pallet 110 slides into contact with the lower cleaning member 71 is, for example, the height Z3 of the upper surface 110A of the degate pallet 110, and the height Z1 of the surface of the lower mold 61 during cleaning (as shown in FIG. 2). The height is approximately the same as that of . The height at which the degate hand 120 makes sliding contact with the upper cleaning member 72 is, for example, the height Z4 of the lower surface 120B of the degate hand 120 and the height Z2 of the surface of the cull 65 of the upper die 62 during cleaning (as shown in FIG. 2). ) is approximately the same height. With such a height, the upper surface 110A of the degate pallet 110 and the lower surface 120B of the degate hand 120 can be suitably cleaned under the same conditions as when cleaning the mold 6.

6 and 7 are side views illustrating a cleaning method for the resin sealing device 1 according to the present embodiment. FIG. 6 shows a state in which the unloader hand 92 has entered the digitator 10. In the illustrated example, since the unloader hand 92 holds the sealed product W' at the bottom, the degate pallet 110 is loaded with the sealed product W' in a clean state. While entering between the degate hand 120 and the degate hand 120, the cleaning member 70 removes dust attached to the upper surface 110A of the degate pallet 110. The lower cleaning member 71 and its dust collection port 73 protrude downward and are in sliding contact with the upper surface 110A of the degate pallet 110, while the upper cleaning member 72 and its dust collection port 74 are inserted into the unloader hand 92 and degate. It is not in contact with the lower surface 120B of the hand 120.

FIG. 7 shows a state in which the unloader hand 92 is retracted outside the degator. In the illustrated example, the cleaning member 70 removes dust attached to the lower surface 120B of the degate hand 120 while the unloader hand 92 retreats to the unloader main body 91. The upper cleaning member 72 and its dust collection port 74 protrude upward and are in sliding contact with the lower surface 120B of the degate hand 120, while the lower cleaning member 71 and its dust collection port 73 are inserted into the unloader hand 92 and degate. It is not in contact with the upper surface 110A of the pallet 110.

As shown in the figure, when cleaning one side of the degate pallet 110 and the degate hand 120, the suction force of the suction source such as a suction pump that sucks through the dust collection ports 73, 74, etc. is greater than when cleaning them at the same time. is not dispersed. Powerful suction power allows efficient dust collection. Note that the order in which the degate pallet 110 and the degate hand 120 are cleaned is not limited to the illustrated example, but may be in the reverse order, or both may be cleaned at the same time. At the time of cleaning, the moving speed of the unloader hand 92 may be slower than when normally transporting the sealed product W'. During cleaning, the spacing S between the degate pallet 110 and the degate hand 120 may be made narrower or wider than when the sealed product W' is normally conveyed.
