[0004] [Patent Document]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2012-43839 Summary of the invention

[0006] [Problems to be solved by the invention]

[0007] Dust such as resin chips may sometimes adhere to the lower surface of the sprue robot due to static electricity or the like. If a sealed product is sandwiched between the sprue tray and the sprue robot while dust is attached to the lower surface of the sprue robot, undesirable conditions such as marks (dents) may sometimes occur on the surface of the sealed product. In this case, the resin sealing device is stopped and the operator cleans the sprue 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 the number of parts.

[0008] [Technical means to solve the problem]

[0009] The resin sealing device of one embodiment of the present invention includes: a pouring gate, which separates useless resin from the seal by clamping the seal sealed by resin between the pouring gate tray and the pouring gate robot that moves up and down relative to the pouring gate tray; and an unloader that takes out the seal from the resin sealing mold and transports it to the pouring gate. The unloader includes: an unloader body that can move between a first standby position that takes out the seal from the resin sealing mold and a second standby position that takes the seal into the pouring gate; 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 that moves to the first standby position, hold the seal sealed by resin, and retreat to the unloader body. The pouring gate tray and the pouring gate robot provide a gap for the unloader robot to move forward and backward from the unloader body that moves to the second standby position to between the pouring gate tray and the pouring gate robot.

[0010] According to the embodiment, the unloader robot can enter between the pouring gate tray and the pouring gate robot. Therefore, for example, if a cleaning component is added to the unloader robot, or the cleaning component already provided on the unloader robot is moved to clean the pouring gate, the dust attached to the pouring gate tray and the pouring gate robot can be removed. In this case, the cleaning component provided near the molded product storage mechanism for cleaning the pouring gate tray can be omitted, thereby reducing the number of parts. In addition, according to the embodiment, the movable range of the unloader is expanded. Therefore, for example, a part of the reciprocating movement of the pouring gate tray can be replaced by the forward and backward movement of the unloader robot to shorten the reciprocating distance of the pouring gate tray. In this case, the area occupied by the pouring gate tray can be reduced, thereby increasing the degree of freedom in the layout design of the resin sealing device.

[0011] In the embodiment, the unloader may also include a cleaning component (cleaner), which is arranged at the front end of the unloader robot. When the unloader robot enters between the pouring gate tray and the pouring gate robot, it can remove dust attached to at least one of the pouring gate tray and the pouring gate robot.

[0012] According to the above-described embodiment, dust adhering to the pouring gate robot and the pouring gate tray can be removed by the cleaning member provided at the front end portion of the unloader robot.

[0013] In the embodiment, the cleaning member may include: a lower cleaning member movable below a lower end of the unloader robot; and an upper cleaning member movable above an upper end of the unloader robot.

[0014] According to the embodiment, when the pouring gate is cleaned, the cleaning component contacts the pouring gate tray and the pouring gate robot. When the pouring gate 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 pouring gate tray and the pouring gate robot.

[0015] In the embodiment, the gate piercing tray can be moved at a height that is lower than the lower end of the unloading machine robot and is in sliding contact with the lower cleaning member in a state of moving downward from the unloading machine robot, and the gate piercing robot can be moved at a height that is higher than the upper end of the unloading machine robot and is in sliding contact with the upper cleaning member in a state of moving upward from the unloading machine robot.

[0016] According to the embodiment, the pouring tray and the pouring robot can be moved to a height where the unloader robot will not collide. Even if there is a gap between the pouring tray, the pouring robot and the unloader robot, the lower cleaning member can be slidably connected to the pouring tray, and the upper cleaning member can be slidably connected to the pouring robot.

[0017] In the described embodiment, 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 arranged along at least one of the lower cleaning member and the upper cleaning member and capable of sucking dust.

[0018] According to the embodiment, the dust attached to the gate tray and the gate robot can be removed efficiently by combining a brush for shaking off dust and a dust collecting port for sucking the dust shaken off by the brush. Since the dust is sucked by the dust collecting port, dust can be prevented from flying to the installation place of the resin sealing device.

[0019] In the above-described embodiment, the cleaning member may also have a function of removing dust adhering to the surface of the resin sealing mold when the unloader robot enters the inside of the resin sealing mold.

[0020] According to the embodiment, the cleaning member already provided on the unloader robot for cleaning the surface of the resin sealing mold can be used to clean the pouring gate tray and the pouring gate robot. Since there is no need to add a cleaning member dedicated to pouring gates, the manufacturing cost of the resin sealing device can be reduced.

[0021] In the embodiment, the resin sealing mold may include a lower mold and an upper mold facing each other, and the gate tray may be able to move at a height where the upper surface of the gate tray is approximately the same height as the surface of the lower mold, and the gate robot may be able to move at a height where the lower surface of the gate robot is approximately the same height as the surface of the upper mold.

[0022] According to the embodiment, when the cleaning member already provided on the unloader robot is transferred to clean the pouring gate tray and the pouring gate robot, the design of the cleaning member and the unloader robot does not need to be changed, thereby suppressing the manufacturing cost of the resin sealing device and making parts common.

[0023] A cleaning method for a resin sealing device according to an embodiment of the present invention includes: a gate, separating useless resin from the sealant by clamping the sealant sealed with resin between a gate tray and a gate robot that moves up and down relative to the gate tray; and an unloader that takes the sealant out of the resin sealing mold and transports it to the gate. The unloader includes: an unloader body that can move between a first standby position for taking the sealant out of the resin sealing mold and a second standby position for moving the sealant into the gate; 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 that has moved to the first standby position, hold the sealant and retreat to the unloader body; and a cleaning member that is provided at the front end of the unloader robot. When the unloading machine robot enters between the pouring gate tray and the pouring gate robot, the cleaning component will remove the dust attached to one of the pouring gate tray and the pouring gate robot. When the unloading machine robot retreats to the unloading machine body, the cleaning component will remove the dust attached to the other of the pouring gate tray and the pouring gate robot.

[0024] According to the embodiment, the dust attached to the pouring tray and the pouring robot can be removed by using the cleaning member provided at the front end of the unloader robot. The pouring tray and the pouring robot are cleaned one by one with a time difference, so that, compared with the case where the pouring tray and the pouring robot are cleaned at the same time, the suction force of the suction pump that sucks the dust from the dust collection port is not dispersed. The strong suction force can be used to efficiently collect dust.

[0085] Suitable embodiments of the present invention are described with reference to the accompanying drawings. In addition, in each figure, those marked with the same symbol have the same or identical 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 accompanying drawings.

[0086] Figure 1 1 is a plan view showing an example of a resin sealing device 1 according to an embodiment of the present invention. The resin sealing device 1 of this embodiment is a resin sealing device for sealing a workpiece W with a resin. Figure 1 As shown, it includes at least a gate 10 and an unloader 9. This embodiment may further 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.

[0087] The workpiece supply module 3 takes out 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 applies pressure 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 appropriately changed.

[0088] The unloader 9 takes out the workpiece sealed with resin, i.e., the sealed product W', from the mold 6 and transports it to the gate 10. The gate 10 separates the useless resin from the sealed product W'. The sealed product storage module (pick and place) 11 receives the sealed product W' separated from the useless resin from the gate 10 by adsorption, etc. and rises, and then descends and stores it in the storage box 12 when the gate tray 110 returns. In the following description, the workpiece supply module 3 and the resin supply module 4 are sometimes collectively referred to as inner modules (3, 4), and the gate 10 and the sealed product storage module 11 are collectively referred to as outer modules (10, 11).

[0089] In the example shown in the figure, the inner modules (3, 4), the plurality of pressing modules 5, and the outer modules (10, 11) are arranged along the X-axis direction. The plurality of pressing modules 5 are arranged in series from the inner modules (3, 4) toward the outer modules (10, 11). The outer modules (10, 11) are arranged on the side opposite to the inner modules (3, 4) when viewed from any pressing module 5. The inner modules (3, 4) and the outer modules (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.

[0090] Figure 2 Yes Figure 1 The pressing module 5 shown in FIG. 1 is a side view of the pressing module 5 as viewed from the side. The pressing module 5 performs resin sealing (molding) on ​​the workpiece W by transfer molding in which the resin supplied from the tank 64 in the mold 6 is filled into the cavity 66 by the plunger 63 and hardened. The pressing module 5 constituting the resin sealing device 1 is not limited to the example shown in the figure, and may be a pressing module that seals the workpiece W by compression molding.

[0091] The workpiece W before resin sealing is, for example, a lead frame equipped with semiconductor elements, an interposer substrate equipped with semiconductor elements, a carrier plate with an adhesive sheet to which semiconductor elements are temporarily attached, etc., and includes a support, semiconductor elements mounted on the support, micro parts such as a micro-electro-mechanical system (MEMS) chip, and electronic devices. The workpiece W may be a workpiece W in which multiple parts are mounted on the support, or a workpiece W in which different types of parts are mixed and mounted on the support.

[0092] like Figure 2As shown, 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 module 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.

[0093] The lower mold 61 is provided with a plurality of slave loaders 8 ( Figure 1 As shown in the figure, a tank 64 for receiving resin such as resin chips is provided. Inside each tank 64, a plunger 63 for pushing up the resin is provided. 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.

[0094] The unloader 9 described above includes: an unloader body 91 that can move in the X-axis direction along the guide 7, and an unloader robot 92 that can move forward and backward in the Y-axis direction from the unloader body 91. 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 vicinity thereof.

[0095] In the example shown in the figure, the cleaning member 70 includes: a lower cleaning member 71, which is provided on the lower surface 92B of the front end of the unloader robot 92; an upper cleaning member 72, which is provided on the upper surface 92A of the front end of the unloader robot 92; and a dust collecting port 73 and a dust collecting port 74, which are respectively provided along the lower cleaning member 71 and the upper cleaning member 72. 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.

[0096] 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 unloader robot 92. The lower cleaning member 71 and the upper cleaning member 72 are brushes with hairs planted in a roller 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-like shape, or rubber scrapers, etc.

[0097] The lower cleaning member 71 and its dust collecting port 73 are configured to be movable downward by a driving source such as an actuator 75 embedded in the unloader robot 92. Similarly, the upper cleaning member 72 and its dust collecting port 74 are configured to be movable upward by 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 are moved to a prescribed height suitable for cleaning the lower mold 61, and the upper cleaning member 72 and the dust collecting port 74 are moved to a prescribed height suitable for cleaning the upper mold 62.

[0098] The height of the surface of the lower mold 61 (for example, the surface of the area for placing the workpiece W) during cleaning 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, a 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, a 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.

[0099] Figure 3 It is a magnified representation Figure 1 The plan view of the unloader 9 and the pouring gate 10 shown. Figure 3 As shown, the unloader body 91 can move between a first standby position X1 for unloading the packaged product W' from the mold 6 and a second standby position X2 for loading the packaged product W' into the gate 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.

[0100] The above-mentioned gate 10 includes: a gate tray 110 that can move along the Y-axis direction, and a gate robot 120 that can move along the Z-axis direction. The gate tray 110 transports the sealed product W' to the unloader 9 or the sealed product storage module 11. The gate 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 gate robot 120.

[0101] Figure 4 1 is a side view showing an example of a pouring tray 110 and a pouring robot 120. The pouring tray 110 and the pouring robot 120 sandwich the sealed product W' between the pouring tray 110 and the pouring robot 120, and the material is removed from the pick pool 65 ( Figure 2 The useless resin R hardened by the above-mentioned method is bent to separate the useless resin R. The separated useless resin R is recovered into the material box 130 of the material removal pool.

[0102] In the example shown in the figure, two pieces of sealing products W' are connected via the useless resin R hardened by the removal pool 65. The gate tray 110 has: a first part (left flap) 111 supporting one of the sealing products W', a second part (connecting part) 112 supporting the useless resin R, and a third part (right flap) 113 supporting the other sealing product W'. Similarly, the gate 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 useless resin R toward the second part 112, and a sixth part 123 pressing the other sealing product W' toward the third part 113.

[0103] The upper surface 110A ( Figure 5 The surfaces of the first portion 111 and the third portion 113 that are in contact with the seal W' are cleaned by the unloader robot 92. The lower surface 120B ( Figure 5 For example, the surfaces of the fourth portion 121 and the sixth portion 123 that are in contact with the sealed product W' are cleaned by the unloader robot 92. Figures 5 to 7 The details will be described later.

[0104] When the useless resin R is separated from the sealing product W', for example, both ends of the first part 111 and the second part 113 of the gate 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 both ends of the fourth part 121 and the sixth part 123 of the gate robot 120 relative to the fifth part 122. In addition, the structure of the gate tray 110 and the gate robot 120 is not limited to the example shown in the figure, and a known structure can be appropriately selected.

[0105] Figure 5 This is a side view of the pouring nozzle 10 of the present embodiment observed from the side. The pouring nozzle 10 of the present embodiment is characterized in that a gap S is provided between the pouring nozzle tray 110 and the pouring nozzle robot 120 so that the unloader robot 92 can move forward and backward. In the example shown in the figure, the cylinder 140 as a driving source for driving the pouring nozzle robot 120 up and down is made long, so that a wider gap S is provided than in the existing equipment.

[0106] According to the present embodiment, since the unloader robot 92 can enter the pouring gate 10, for example, a cleaning member is provided on the unloader robot 92 to remove dust attached to the pouring gate tray 110 and the pouring gate robot 120. The resin sealing device 1 is stopped, and the operator's frequency of cleaning the pouring gate robot 120 and the like is reduced, which can reduce the burden on the operator. The cleaning member provided for cleaning the pouring gate tray in the existing resin sealing device can be omitted, thereby reducing the number of parts.

[0107] As a cleaning member for removing dust attached to the gate-making robot 120, etc., the reference Figure 2 The cleaning member 70 for cleaning the mold described above may be supplemented with a novel cleaning member. When the cleaning member 70 is transferred, the pouring gate tray 110 can be horizontally moved at a height lower than the lower end (e.g., lower surface 92B) of the unloading machine robot 92 and in sliding contact with the lower cleaning member 71 in a state of moving downward from the unloading machine robot 92. The pouring gate robot 120 that moves up and down can be vertically moved to a height higher than the upper end (e.g., upper surface 92A) of the unloading machine robot 92 and in sliding contact with the upper cleaning member 72 in a state of moving upward from the unloading machine robot 92.

[0108] The height at which the pouring gate tray 110 and the lower cleaning member 71 are in sliding contact is, for example, a height Z3 of the upper surface 110A of the pouring gate tray 110 and a height Z1 of the surface of the lower mold 61 during cleaning ( Figure 2 The height at which the gate manipulator 120 and the upper cleaning member 72 slide is, for example, the height Z4 of the lower surface 120B of the gate manipulator 120 is the same as the height Z2 ( Figure 2 If it is such a height, the upper surface 110A of the gate tray 110 and the lower surface 120B of the gate robot 120 can be suitably cleaned under the same conditions as when the mold 6 is cleaned.

[0109] Figure 6 and Figure 7 It is a side view explaining the cleaning method of the resin sealing device 1 of this embodiment. Figure 6The state in which the unloader robot 92 enters the pouring gate 10 is shown. In the example shown in the figure, since the sealant W' is held on the lower side of the unloader robot 92, in order to load the sealant W' on the pouring gate tray 110 in a neat state, the cleaning member 70 removes dust attached to the upper surface 110A of the pouring gate tray 110 while entering between the pouring gate tray 110 and the pouring gate robot 120. The lower cleaning member 71 and its dust collecting port 73 protrude downward and slide on the upper surface 110A of the pouring gate tray 110, while the upper cleaning member 72 and its dust collecting port 74 are immersed in the unloader robot 92 and do not contact the lower surface 120B of the pouring gate robot 120.

[0110] Figure 7 The state in which the unloader robot 92 is retreated to the outside of the pouring gate is shown. In the example shown in the figure, the cleaning member 70 removes dust attached to the lower surface 120B of the pouring gate robot 120 while the unloader robot 92 is retreated 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 pouring gate 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 pouring gate tray 110.

[0111] As shown in the figure, when the pouring gate tray 110 and the pouring gate 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 powerful suction force can be used to efficiently collect dust. In addition, the order of cleaning the pouring gate tray 110 and the pouring gate 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 when the sealed product W' is normally transported. When cleaning, the interval S between the pouring gate tray 110 and the pouring gate robot 120 can be narrower than when the sealed product W' is normally transported, or it can be wider than usual.

[0112] The above-described embodiments 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 those illustrated and can be appropriately changed.
