Due to static electricity, etc., dust such as resin scraps may sometimes adhere to the lower surface of the gutter robot. If a sealant is sandwiched between the gutter tray and the gutter robot while dust is attached to the lower surface of the gutter robot, defects such as scratches (dents) may sometimes occur on the surface of the sealant. In this case, the resin sealing device is stopped and the operator cleans the gutter robot. Therefore, the purpose of the present invention is to provide a resin sealing device and a cleaning method thereof that can reduce the burden on the operator and reduce the number of parts.

A resin sealing device in one form of the present invention includes: a grouting port, which separates useless resin from the sealing product by sandwiching the sealing product sealed with resin between a grouting port tray and a grouting port robot that moves up and down relative to the grouting port tray; and a loader that takes the sealing product out of the resin sealing mold and transports it to the grouting port. The loader includes: an unloader body that can move between a first standby position for taking the sealing product out of the resin sealing mold and a second standby position for moving the sealing product into the grouting port; and an unloader robot that can move forward and backward from the unloader body, and enter the interior of the resin sealing mold from the unloader body moved to the first standby position, hold the sealing product sealed with resin, and retreat to the unloader body. The grouting port tray and the grouting port robot provide a gap for the unloader robot to move from the unloader body moved to the second standby position to the grouting port tray and the grouting port robot.

According to the above configuration, the unloader robot can enter between the grate tray and the grate robot. Therefore, for example, if a cleaning member is added to the unloader robot or a cleaning member already provided on the unloader robot is transferred to the grate cleaning, dust attached to the grate tray and the grate robot can be removed. In this case, the cleaning member provided near the molded product storage mechanism for cleaning the grate tray can be omitted, thereby reducing the number of parts. In addition, according to the above configuration, the range in which the unloader can move is expanded. Therefore, for example, a part of the reciprocating movement of the gushing tray can be replaced by the forward and backward movement of the unloading machine robot to shorten the reciprocating distance of the gushing tray. In this case, the occupied area of the gushing tray can be reduced, thereby increasing the degree of freedom in the layout design of the resin sealing device.

In the above embodiment, the unloader may also include a cleaning member (cleaner), which is disposed at the front end of the unloader robot. When the unloader robot enters between the grout tray and the grout robot, the cleaning member (cleaner) can remove dust attached to at least one of the grout tray and the grout robot.

According to the above configuration, dust adhering to the grate manipulator and the grate tray can be removed by a cleaning member provided at the front end of the unloader manipulator.

In the described form, the cleaning member may include: a lower cleaning member capable of moving downwardly than the lower end of the unloading machine robot; and an upper cleaning member capable of moving upwardly than the upper end of the unloading machine robot.

According to the above configuration, when the grouting port is cleaned, the cleaning component contacts the grouting port tray and the grouting port robot. When the grouting port is not cleaned, the height of the lower cleaning component and the upper cleaning component can be adjusted so that the cleaning component does not contact the grouting port tray and the grouting port robot.

In the above configuration, the gushing port tray may be moved at a height lower than the lower end of the unloading machine robot and in sliding contact with the lower cleaning member when the unloading machine robot moves downward, and the gushing port robot may be moved at a height higher than the upper end of the unloading machine robot and in sliding contact with the upper cleaning member when the unloading machine robot moves upward.

According to the above configuration, the gushing port tray and the gushing port robot can be moved to a height where the unloading machine robot will not collide with them. Even if there is a gap between the gushing port tray, the gushing port robot and the unloading machine robot, the lower cleaning member can be slidably connected to the gushing port tray, and the upper cleaning member can be slidably connected to the gushing port robot.

In the above configuration, the lower cleaning member and the upper cleaning member may be brushes extending in a direction intersecting the forward and backward direction of the unloader robot, and the cleaning member may have a dust collecting port disposed along at least one of the lower cleaning member and the upper cleaning member and capable of sucking dust.

According to the above configuration, the dust adhering to the grate tray and the grate robot can be removed efficiently by combining a brush for catching dust and a dust collecting port for sucking the dust caught by the brush. Since the dust is sucked by the dust collecting port, it is possible to prevent the dust from being scattered to the installation location of the resin sealing device.

In the above-mentioned form, the cleaning member can also have the function of removing dust attached to the surface of the resin sealing mold when the unloading machine robot enters the interior of the resin sealing mold.

According to the above configuration, the cleaning member already installed on the unloading machine robot for cleaning the surface of the resin sealing mold can be transferred to clean the gutter tray and the gutter robot. Since there is no need to add a cleaning member dedicated to the gutter, the manufacturing cost of the resin sealing device can be suppressed.

In the above-mentioned form, the resin sealing mold may include a lower mold and an upper mold facing each other up and down, and the gutter tray may also be able to move at a height where the upper surface of the gutter tray is approximately the same as the surface of the lower mold, and the gutter robot may also be able to move at a height where the lower surface of the gutter robot is approximately the same as the surface of the upper mold.

According to the above configuration, when the cleaning member already provided on the unloading machine robot is transferred to clean the gushing port tray and the gushing port robot, the design of the cleaning member and the unloading machine robot does not need to be changed, thereby suppressing the manufacturing cost of the resin sealing device and making the parts common.

A cleaning method for a resin sealing device in one form of the present invention includes: a grouting port, which separates useless resin from the sealing product by sandwiching the sealing product sealed with resin between a grouting port tray and a grouting port robot that moves up and down relative to the grouting port tray; and an unloader, which takes the sealing product out of the resin sealing mold and transports it to the grouting port. The unloader includes: an unloader body, which can move between a first standby position for removing the sealed product from the resin sealing mold and a second standby position for moving the sealed product into the grouting port; an unloader robot, which can move forward and backward from the unloader body and enter the interior of the resin sealing mold from the unloader body moved to the first standby position to hold the sealed product and retreat to the unloader body; and a cleaning component, which is arranged at the front end of the unloader robot. When the unloader robot enters between the grout tray and the grout robot, the cleaning component removes the dust attached to one of the grout tray and the grout robot. When the unloader robot retreats to the unloader body, the cleaning component removes the dust attached to the other of the grout tray and the grout robot.

According to the above configuration, dust adhering to the grate tray and the grate robot can be removed by using a cleaning member provided at the front end of the unloader robot. The grate tray and the grate robot are cleaned one by one with a time difference, so that, for example, the suction force of the suction pump that sucks dust from the dust collection port is not dispersed compared to the case where the grate tray and the grate robot are cleaned at the same time. Dust can be efficiently collected using a strong suction force.

According to the present invention, a resin sealing device and a cleaning method thereof can be provided which can reduce the burden on operators and reduce the number of parts.

The suitable implementation mode of the present invention is described with reference to the accompanying drawings. In addition, in each figure, the same symbol is marked with the same or the same structure. In order to clarify the relationship between the drawings and help understand the positional relationship of each component, for convenience, an orthogonal coordinate system including the X-axis, Y-axis and Z-axis is marked in each drawing. The surface including the X-axis and the Y-axis is set as the "XY surface", the arrow direction of the Z-axis is set as upward, and the direction opposite to the arrow of the Z-axis is set as downward for description. When observed from the operator of the resin sealing device 1, the X-axis direction is, for example, the left-right direction, and the Y-axis direction is, for example, the front-back direction. Below, the present invention is described in detail with reference to the drawings.

FIG. 1 is a plan view showing an example of a resin sealing device 1 of an embodiment of the present invention. The resin sealing device 1 of the present embodiment is a resin sealing device for sealing a workpiece W with resin, and as shown in FIG. 1 , includes at least a grouting port 10 and an unloader 9. The present embodiment may also include a workpiece supply module 3, a resin supply module 4, a pressing module 5, a loader 8, a molded product storage module 11, etc. as arbitrary structures.

The workpiece supply module 3 takes the workpiece W before resin sealing from the supply magazine 2 and supplies it to the loader 8. The resin supply module 4 supplies the resin formed in small pieces to the loader 8. The loader 8 transports the sealed product W' supplied from the workpiece supply module 3 to the mold (resin sealing mold) 6 of the pressing module 5. The pressing module 5 clamps the supplied workpiece W and presses it to perform resin sealing (molding). In the example shown in the figure, the resin sealing device 1 includes four pressing modules 5. The number of pressing modules 5 is not limited to the example shown in the figure, and can also be changed as appropriate.

The unloader 9 removes the workpiece sealed with resin, i.e., the sealed product W', from the mold 6 and transports it to the pouring port 10. The pouring port 10 separates the unnecessary resin from the sealed product W'. The sealed product storage module (pick and place) 11 receives the sealed product W' separated from the unnecessary resin from the pouring port 10 by adsorption, etc. and rises. When the pouring port tray 110 returns, it descends and is stored in the storage box 12. In the following description, the workpiece supply module 3 and the resin supply module 4 are sometimes collectively referred to as the inner module (3, 4), and the pouring port 10 and the sealed product storage module 11 are collectively referred to as the outer module (10, 11).

In the example shown in the figure, the inner module (3, 4), the plurality of pressing modules 5, and the outer module (10, 11) are arranged along the X-axis direction. The plurality of pressing modules 5 are arranged in series from the inner module (3, 4) toward the outer module (10, 11). The outer module (10, 11) is arranged on the side opposite to the inner module (3, 4) when viewed from any pressing module 5. The inner module (3, 4) and the outer module (10, 11) may also be arranged on the same side when viewed from any pressing module 5. The loader 8 and the unloader 9 are configured to be movable along the guide 7 extending in the X-axis direction.

FIG. 2 is a side view of the pressing die 5 shown in FIG. 1 . The pressing die 5 performs resin sealing (molding) on the workpiece W by transfer molding in which the resin in the tank 64 supplied to the mold 6 is filled into the mold cavity 66 by the plunger 63 and hardened. The pressing die 5 constituting the resin sealing device 1 is not limited to the example shown in the figure, and may also be a pressing die that seals the workpiece W by compression molding.

The workpiece W before resin sealing is, for example, a lead frame equipped with semiconductor components, an interposer substrate equipped with semiconductor components, a carrier plate with an adhesive sheet temporarily bonded with semiconductor components, etc., and includes a support body, a semiconductor component mounted on the support body, a micro-electromechanical system (MEMS) chip, an electronic device, etc. Micro parts. The workpiece W may be a workpiece W in which multiple parts are mounted on a support body, or a workpiece W in which different types of parts are mixed and mounted on a support body.

As shown in FIG. 2 , the mold 6 includes a lower mold 61 and an upper mold 62 facing each other in the Z-axis direction (up and down direction). In addition to the mold 6, the pressing mold 5 also includes a pressing mechanism 50 for opening and closing the mold 6. The pressing mechanism 50 includes: a fixed platen 52, a movable platen 51 that can move in the Z-axis direction relative to the fixed platen 52, and a tie bar 53 for positioning the fixed platen 52 and the movable platen 51. In the example shown in the figure, the lower mold 61 is installed on the movable platen 51, and the upper mold 62 is installed on the fixed platen 52. It can also be configured so that the lower mold 61 becomes the fixed side and the upper mold 62 becomes the movable side.

In the lower mold 61, there are multiple tanks 64 for receiving resin such as resin chips from the loader 8 (shown in Figure 1). Inside each tank 64, there is a plunger 63 for pushing the resin up. In the upper mold 62, a material removal pool 65 for heating the resin is provided at a position of the lower mold 61 facing the tank 64, and a mold cavity 66 for shaping the resin is provided at a position facing the workpiece W. The mold cavity 66 is connected to the material removal pool 65.

The unloader 9 described above includes: an unloader body 91 that can move along the guide 7 in the X-axis direction, and an unloader robot 92 that can move forward and backward from the unloader body 91 in the Y-axis direction. The unloader robot 92 enters between the lower mold 61 and the upper mold 62 to remove the sealed product W' sealed with resin. A cleaning member 70 for cleaning the mold 6 is provided at the front end including the front end of the unloader robot 92 and the part near it.

In the illustrated example, the cleaning member 70 includes: a lower cleaning member 71, which is disposed on the lower surface 92B of the front end of the unloading machine manipulator 92; an upper cleaning member 72, which is disposed on the upper surface 92A of the front end of the unloading machine manipulator 92; and a dust collecting port 73 and a dust collecting port 74, which are disposed along the lower cleaning member 71 and the upper cleaning member 72, respectively. The dust collecting port 73 and the dust collecting port 74 are connected to a suction source such as a suction pump through piping or the like.

The lower cleaning member 71 and the upper cleaning member 72 extend in the X-axis direction intersecting the Y-axis direction, which is the forward and backward direction of the unloading machine robot 92. The lower cleaning member 71 and the upper cleaning member 72 are brushes with hairs planted in a roll shape so that the hair tips form a circumferential surface, and are driven to rotate around the X-axis. The lower cleaning member 71 and the upper cleaning member 72 are not limited to the examples shown in the figure, and can be brushes with hairs planted in a comb shape, or rubber scrapers, etc.

The lower cleaning member 71 and its dust collecting port 73 are configured to be able to move downward through a driving source such as an actuator 75 embedded in the unloading machine manipulator 92. Similarly, the upper cleaning member 72 and its dust collecting port 74 are configured to be able to move upward through a driving source such as an actuator 75 and an actuator 76. During cleaning, the lower cleaning member 71 and the dust collecting port 73 move to a specified height suitable for cleaning the lower mold 61, and the upper cleaning member 72 and the dust collecting port 74 move to a specified height suitable for cleaning the upper mold 62.

The height of the surface of the lower mold 61 during cleaning (for example, the surface of the area for placing the workpiece W) is set to Z1, and the height of the surface of the material removal pool 65 of the upper mold 62 is set to Z2. The specified height suitable for cleaning the lower mold 61 is, for example, the height at which the tip of the lower cleaning member 71 contacts the surface of the lower mold 61 (height Z1) and is slightly bent. The specified height suitable for cleaning the upper mold 62 is, for example, the height at which the tip of the upper cleaning member 72 such as a cleaning brush contacts the surface of the material removal pool 65 and the cavity 66 of the upper mold 62 at height Z2 and is slightly bent.

FIG3 is an enlarged plan view of the unloader 9 and the grouting port 10 shown in FIG1. As shown in FIG3, the unloader body 91 can move between the first standby position X1 for removing the packaged product W' from the mold 6 and the second standby position X2 for moving the packaged product W' into the grouting port 10. The unloader robot 92 enters the unloader body 91 or the mold 6 moved to the first standby position X1, and can hold the sealed product W' sealed with resin and retreat to the unloader body 91.

The gushing port 10 described above includes: a gushing port tray 110 that can move along the Y-axis direction, and a gushing port robot 120 that can move along the Z-axis direction. The gushing port tray 110 transports the sealed product W' to the unloader 9 or the sealed product storage module 11. The gushing port tray 110 reciprocates between the first position Y1 for receiving the sealed product W' from the unloader 9 and the third position Y3 for delivering the sealed product W' to the sealed product storage module 11 via the second position Y2 directly below the gushing port robot 120.

FIG4 is a side view showing an example of a gutter tray 110 and a gutter robot 120. The gutter 10 sandwiches the sealing product W' between the gutter tray 110 and the gutter robot 120, and bends the useless resin R hardened by the pick tank 65 (shown in FIG2), etc., to separate the useless resin R. The separated useless resin R is recovered into the pick tank box 130.

In the example shown in the figure, two pieces of sealing products W' are connected via the waste resin R hardened by the pick tank 65. The guillotine tray 110 has: a first part (left flap) 111 supporting one of the sealing products W', a second part (connecting part) 112 supporting the waste resin R, and a third part (right flap) 113 supporting the other sealing product W'. Similarly, the guillotine robot 120 has: a fourth part 121 pressing one of the sealing products W' toward the first part 111, a fifth part 122 pressing the waste resin R toward the second part 112, and a sixth part 123 pressing the other sealing product W' toward the third part 113.

The upper surface 110A (shown in FIG. 5) of the gushing mouth tray 110 described later is, for example, the surface of the first part 111 and the third part 113 in contact with the sealing product W', and is cleaned by the unloader robot 92. The lower surface 120B (shown in FIG. 5) of the gushing mouth robot 120 described later is, for example, the surface of the fourth part 121 and the sixth part 123 in contact with the sealing product W', and is cleaned by the unloader robot 92. The cleaning performed by the unloader robot 92 will be described in detail later with reference to FIGS. 5 to 7.

When separating the useless resin R from the sealing product W', for example, the first part 111 and the two ends of the third part 113 of the guillotine tray 110 are lifted relative to the second part 112. The useless resin R is bent relative to the sealing product W', and the useless resin R is broken at the boundary with the sealing product W'. The useless resin R can also be bent by pressing the two ends of the fourth part 121 and the sixth part 123 of the guillotine robot 120 relative to the fifth part 122. In addition, the structure of the guillotine tray 110 and the guillotine robot 120 is not limited to the example shown in the figure, and a known structure can be appropriately selected.

FIG5 is a side view of the gushing port 10 of the present embodiment as viewed from the side. The gushing port 10 of the present embodiment is characterized in that a gap S is provided between the gushing port tray 110 and the gushing port robot 120 so that the unloader robot 92 can move forward and backward. In the illustrated example, the cylinder 140 as a driving source for driving the gushing port robot 120 up and down is made longer, thereby providing a wider gap S than the existing equipment.

According to this embodiment, since the unloader robot 92 can enter the grouting port 10, for example, a cleaning member is provided on the unloader robot 92 to remove dust attached to the grouting port tray 110 and the grouting port robot 120. The resin sealing device 1 is stopped and the operator's frequency of cleaning the grouting port robot 120 is reduced, which can reduce the burden on the operator. The cleaning member provided in the existing resin sealing device for cleaning the grouting port tray can be omitted, thereby reducing the number of parts.

As a cleaning member for removing dust attached to the gushing mouth robot 120, etc., the cleaning member 70 for mold cleaning described with reference to FIG. 2 can be transferred, or a new cleaning member can be added. When the cleaning member 70 is transferred, the gushing mouth tray 110 can move horizontally at a height lower than the lower end (e.g., lower surface 92B) of the unloading machine robot 92 and slidingly contacting the lower cleaning member 71 in the state of moving downward from the unloading machine robot 92. The gushing mouth robot 120 that moves up and down can move vertically to a height higher than the upper end (e.g., upper surface 92A) of the unloading machine robot 92 and slidingly contacting the upper cleaning member 72 in the state of moving upward from the unloading machine robot 92.

The height at which the sprue tray 110 and the lower cleaning member 71 slide is, for example, the height Z3 of the upper surface 110A of the sprue tray 110 is approximately the same height as the height Z1 (shown in FIG. 2) of the surface of the lower mold 61 during cleaning. The height at which the sprue manipulator 120 and the upper cleaning member 72 slide is, for example, the height Z4 of the lower surface 120B of the sprue manipulator 120 is approximately the same height as the height Z2 (shown in FIG. 2) of the surface of the pick pool 65 of the upper mold 62 during cleaning. If it is such a height, the upper surface 110A of the sprue tray 110 and the lower surface 120B of the sprue manipulator 120 can be properly cleaned under the same conditions as when cleaning the mold 6.

Fig. 6 and Fig. 7 are side views for explaining the cleaning method of the resin sealing device 1 of the present embodiment. Fig. 6 shows the state in which the unloader robot 92 enters the grouting port 10. In the illustrated example, since the unloader robot 92 holds the sealing product W' at the lower side, in order to load the sealing product W' on the grouting port tray 110 in a neat state, the cleaning member 70 removes the dust attached to the upper surface 110A of the grouting port tray 110 while entering between the grouting port tray 110 and the grouting port robot 120. The lower cleaning member 71 and its dust collecting port 73 protrude downward and slide in contact with the upper surface 110A of the grate tray 110. On the other hand, the upper cleaning member 72 and its dust collecting port 74 are immersed in the unloading machine robot 92 and do not contact the lower surface 120B of the grate robot 120.

FIG7 shows the state where the unloader robot 92 retreats outside the grouting port. In the illustrated example, the cleaning member 70 removes dust attached to the lower surface 120B of the grouting port robot 120 while the unloader robot 92 retreats to the unloader body 91. The upper cleaning member 72 and its dust collecting port 74 protrude upward and slide with the lower surface 120B of the grouting port robot 120, while the lower cleaning member 71 and its dust collecting port 73 are immersed in the unloader robot 92 and do not contact the upper surface 110A of the grouting port tray 110.

As shown in the figure, when the gushing tray 110 and the gushing robot 120 are cleaned one by one, the suction force of the suction source such as the suction pump that performs suction through the dust collecting port 73, the dust collecting port 74, etc. is not dispersed compared to the case where they are cleaned at the same time. The strong suction force can be used to efficiently collect dust. In addition, the order of cleaning the gushing tray 110 and the gushing robot 120 is not limited to the example shown in the figure, and can be the opposite order, or both can be cleaned at the same time. When cleaning, the moving speed of the unloader robot 92 can be slower than the normal time of conveying the sealed product W'. During cleaning, the distance S between the gutter tray 110 and the gutter robot 120 can be made narrower or wider than normal when conveying the sealed product W'.

The embodiments described above are used to make the present invention easy to understand and do not limit the present invention. The various elements and their configurations, materials, conditions, shapes, and sizes included in the embodiments are not limited to the examples and can be changed as appropriate. In addition, the structures shown in different embodiments can be partially replaced or combined with each other.
