Description

[Technical field]

[0001] The disclosed embodiment relates to a resin sealing apparatus. [Background technology]

[0002] Conventionally, there has been known a resin sealing apparatus for sealing a workpiece such as a lead frame with resin. For example, Patent Document 1 discloses a resin sealing apparatus including a conveying section that receives the workpiece to be sealed with resin from a delivery section of a workpiece supply unit and conveys the received workpiece to a mold. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-300975 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the resin sealing apparatus described in Patent Document 1 has a heating means for preheating the molded product at the transfer section of the molded product supply unit, so if the distance from the transfer section of the molded product supply unit to the mold is long, the temperature of the molded product heated by the heating means will decrease during transportation.

[0005] Therefore, instead of providing a heating means in the transfer section of the workpiece supply unit, it is possible to provide a transfer section having a heating means for preheating the workpiece between the transfer section of the workpiece supply unit and the die. In this case, the conveying section must receive the workpiece from the transfer section of the workpiece supply unit, supply it to the transfer section having the heating means, receive the workpiece from the transfer section having the heating means, convey the received workpiece to the die, and supply the workpiece to the die.

[0006] Therefore, for example, there is a possibility that the supply of the molded article to the mold may not be able to keep up with the molding cycle of the mold. This is true even if the transfer part provided between the transfer part of the workpiece supply unit and the mold is a transfer part other than the transfer part having the heating means.

[0007] One aspect of an embodiment has been made in view of the above, and has an object to provide a resin sealing apparatus that can efficiently transport a member to be resin-sealed. [Means for solving the problem]

[0008] A resin sealing apparatus according to an aspect of the embodiment includes a first conveying section and a second conveying section. The first conveying section conveys a first member to be sealed with resin. The second conveying section has a common moving path with the first conveying section and conveys a second member to be sealed with resin. The first conveying section receives the first member from the first delivery section. Thus, the first member is supplied to a second delivery part that is located at a position different from the first delivery part. The second conveying section includes: The first member Second member As the first Receive from the delivery section 2 and supplying the second member to a third transfer section that is located at a position different from each of the first transfer section and the second transfer section. . Effect of the Invention

[0009] According to one aspect of the embodiment, it is possible to provide a resin sealing apparatus capable of efficiently transporting a member to be resin sealed. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of a resin sealing device disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiment described below.

[0012] <1. Resin sealing equipment configuration> 1 and 2, a resin sealing apparatus 1 according to an embodiment includes a component supply unit 2, a resin sealing unit 3, an output unit 4, an inloader 5, and an outloader 6. In Fig. 1, the direction perpendicular to the paper surface and approaching the paper surface is the downward direction, and the direction perpendicular to the paper surface and moving away from the paper surface is the upward direction. Hereinafter, the movement direction of the inloader 5 and the outloader 6 will be referred to as the left-right direction, and the directions perpendicular to each of the up-down direction and the left-right direction will be referred to as the front-rear direction.

[0013] The resin sealing apparatus 1 further includes a control device 50, and each of the component supply unit 2, the resin sealing unit 3, the output unit 4, the inloader 5, and the outloader 6 is controlled by the control device 50.

[0014] 3, the member supply unit 2 includes a workpiece supply device 21 that supplies a plurality of workpieces 8, which are members to be resin-sealed by the resin sealing device 1, to the inloader 5, and a resin tablet supply device 22 that supplies resin tablets 9, which are a resin material for resin sealing, to the inloader 5. The workpieces 8 are, for example, a lead frame on which a plurality of semiconductor elements are mounted, or a substrate on which a plurality of semiconductor elements are mounted.

[0015] In the molding work supply device 21, the molding work pieces 8 are loaded in multiple stages in a supply magazine 211. The molding work pieces 8 are pushed from the front to the rear by a pusher (not shown), and are pulled by a pull section (not shown) that grips an end of the molding work piece 8 protruding from the supply magazine 211, transported along a rail 212, and supplied to a delivery section 213. The pull section transports the molding work pieces 8 one by one. In the delivery section 213, two molding work pieces 8 are placed at preset positions by the transport by the pull section, and these two molding work pieces 8 are supplied to the inloader 5. The delivery section 213 is an example of a first delivery section in the claims.

[0016] As shown in FIG. 1, the resin sealing unit 3 includes a plurality of preheating sections 311, 312, 313, and 314 each for preheating the molded article 8, and a plurality of resin sealing dies 321, 322, 323, and 324 for sealing the molded article 8 with resin, respectively.

[0017] The multiple preheating units 311, 312, 313, and 314 are arranged in the left-right direction in FIG. 1. Each of the multiple preheating units 311, 312, 313, and 314 heats two molded articles 8 simultaneously, and preheats the two molded articles 8 simultaneously. Each of the multiple preheating units 311, 312, 313, and 314 is located on a moving path common to the first conveying unit 51 and the second conveying unit 52. Also, as shown in FIG. 1, each of the multiple preheating units 311, 312, 313, and 314 is arranged such that the distance between the respective center positions of the corresponding resin sealing molds among the multiple resin sealing molds 321, 322, 323, and 324 is a distance B in the left-right direction. This distance B is equal to the distance A between the respective center positions of the first conveying unit 51 and the second conveying unit 52. Hereinafter, when the multiple preheating units 311, 312, 313, and 314 are referred to without being individually distinguished, they may be referred to as preheating unit 31.

[0018] The preheating section 311 is provided with a delivery section 3111 for receiving and delivering the molded article 8, and the preheating section 312 is provided with a delivery section 3112 for receiving and delivering the molded article 8. The preheating section 313 is provided with a delivery section 3113 for receiving and delivering the molded article 8, and the preheating section 314 is provided with a delivery section 3114 for receiving and delivering the molded article 8. The molded article 8 supplied to the delivery sections 3111, 3112, 3113, and 3114 is heated by a heater (not shown). Hereinafter, when the multiple delivery sections 3111, 3112, 3113, and 3114 are referred to without being individually distinguished, they may be referred to as the delivery section 311. The delivery section 311 is an example of a second delivery section in the claims.

[0019] The multiple resin sealing molds 321, 322, 323, and 324 are arranged in the left-right direction in FIG. 1. Each of the resin sealing molds 321, 322, 323, and 324 has a lower mold and an upper mold. The structures of the lower mold and the upper mold are similar to those of a general resin sealing mold having a chess block or a cavity block, so a description thereof will be omitted here. Hereinafter, when each of the multiple resin sealing molds 321, 322, 323, and 324 is shown without being distinguished from one another, it may be referred to as a resin sealing mold 32. The upper mold of the resin sealing mold 32 is not shown in FIG. 1.

[0020] The resin sealing mold 32 receives the two molded articles 8 and six resin tablets 9 supplied by the inloader 5 by, for example, moving the lower mold upward from the inloader 5. The resin sealing mold 32 places the two molded articles 8 and the six resin tablets 9 in a space surrounded by the upper and lower molds, and melts the six resin tablets 9 by heating the upper and lower molds while applying pressure to the space, thereby generating two molded articles 10. Each molded article 10 is connected to another molded article 10 by a cull, a runner, or the like.

[0021] The output unit 4 includes a degating section 40, an output magazine section 41, and a pickup section 42. The degating section 40 removes unnecessary resin portions such as culls and runners from each molded product 10. The pickup section 42 transports the molded products 10 from which unnecessary portions have been removed by the degating section 40 to the output magazine section 41.

[0022] The inloader 5 includes a first conveying section 51 and a second conveying section 52. The first conveying section 51 and the second conveying section 52 are integrated, attached to a rail 7 provided in the resin sealing apparatus 1, and move along the rail 7. In the example shown in FIG. 1, the rail 7 is laid in the left-right direction, and the first conveying section 51 and the second conveying section 52 move in the left-right direction along the rail 7. In this way, the first conveying section 51 and the second conveying section 52 have a common movement path in the left-right direction.

[0023] The first transport section 51 moves along the rails 7 between a position vertically facing the delivery section 213 of the workpiece supply device 21 to a position vertically facing the preheating section 314. The first transport section 51 is provided with a gripping mechanism that simultaneously grips two workpieces 8, and can hold two workpieces 8 simultaneously by being gripped by this gripping mechanism.

[0024] The first conveying section 51 may have a suction mechanism instead of the gripping mechanism. In this case, the first conveying section 51 can simultaneously hold two molding targets 8 by suction with the suction mechanism. Note that the first conveying section 51 may have a configuration capable of receiving and supplying the molding targets 8, and the mechanism for holding the molding targets 8 is not limited to the gripping mechanism and the suction mechanism.

[0025] The first conveying section 51 is arranged to be movable upward relative to the molding work supply device 21. When the first conveying section 51 is positioned above the delivery section 213 of the molding work supply device 21, the delivery section 213 rises to a height at which the first conveying section 51 can receive the molding work 8, and the first conveying section 51 receives the two molding work 8 from the delivery section 213 and conveys the received two molding work 8 to above each preheating section 31. Then, the preheating section 31 rises to a height at which the first conveying section 51 can receive the molding work 8, and receives the two molding work 8 from the first conveying section 51. In this way, the first conveying section 51 supplies the molding work 8 to each preheating section 31. The molding work 8 received by the first conveying section 51 at the delivery section 213 is an example of a first member in the claims.

[0026] The second transport section 52 moves along the rails 7 from a position closer to the transfer section 213 of the molded product supply device 21 in the left-right direction than the resin tablet supply device 22 to a position facing the resin sealing mold 324 in the front-rear direction. The second transport section 52 is provided with a gripping mechanism for gripping the two molded products 8 and the six resin tablets 9, and can hold the two molded products 8 and the six resin tablets 9 simultaneously by means of this gripping mechanism.

[0027] The second conveying section 52 may have a suction mechanism instead of the gripping mechanism. In this case, the second conveying section 52 can simultaneously hold two molding targets 8 and six resin tablets 9 by suction with the suction mechanism. Note that the second conveying section 52 may have a configuration capable of receiving and supplying each of the molding targets 8 and the resin tablets 9, and the mechanism for holding the molding targets 8 and the resin tablets 9 is not limited to the gripping mechanism and the suction mechanism.

[0028] The second transport section 52 also has a moving mechanism that moves the gripping mechanism or the suction mechanism in the front-rear direction perpendicular to the moving direction (left-right direction). By using this moving mechanism, the second transport section 52 can move the gripping mechanism or the suction mechanism to a position facing the resin sealing die 32 in the up-down direction. In this state, the two molded articles 8 and the six resin tablets 9 are delivered from the second transport section 52 to the resin sealing die 32.

[0029] The second conveying section 52 is arranged to be movable upward with respect to the resin tablet supplying device 22 and the preheating section 31. When the second conveying section 52 is located above the resin tablet supplying device 22, the resin tablet supplying device 22 rises to a position where the second conveying section 52 can receive the resin tablets 9, and the second conveying section 52 receives six resin tablets 9 from the resin tablet supplying device 22 and conveys the received six resin tablets 9 to above the respective preheating sections 31. Then, the preheating section 31 rises to a height where the second conveying section 52 can receive the molded article 8, and the second conveying section 52 receives the two preheated molded articles 8 from each preheating section 31. Then, the second conveying section 52 conveys the received two preheated molded articles 8 and six resin tablets 9 to above the lower mold of each resin sealing mold 32. The lower die of the resin sealing die 32 rises to a height where it can receive the molded articles 8 and resin tablets 9 from the second conveying section 52, and receives the two molded articles 8 and six resin tablets 9 conveyed from the second conveying section 52. In this manner, the second conveying section 52 supplies the molded articles 8 and the resin tablets 9 to each of the resin sealing die 32. The resin sealing die 32 is an example of a third delivery section in the claims.

[0030] The outloader 6 receives the two molded articles 10 from the resin sealing mold 32, transports the two received molded articles 10 to the degating unit 40, and supplies the two transported molded articles 10 to the degating unit 40. The outloader 6 is attached to a rail 7 and can move along the rail 7. The outloader 6 may be configured to be attached to a rail different from the rail 7 and move.

[0031] <2. Operation of Inloader 5> Next, the operation of the inloader 5 will be specifically described with reference to Figures 4 to 10. For convenience of explanation, the upper die of the resin sealing die 32 is not shown in Figures 4 to 10.

[0032] The inloader 5 is controlled by the control device 50 as described above. In the example shown in Fig. 4, two molded articles 8 are supplied by the inloader 5 to each of the delivery sections 3111, 3112, and 3113 of the preheating sections 311, 312, and 313, respectively, and the resin sealing mold 321 is in a state where there is no molded article 8 or molded article 10, and the resin sealing mold 322 is in a state where there is a molded article 10.

[0033] 4, the first conveying section 51 of the inloader 5 receives the two workpieces 8 from the delivery section 213 of the workpiece supply device 21. The delivery section 213 moves upward, for example, to a position where the first conveying section 51 can receive the two workpieces 8. When the gripping mechanism or suction mechanism of the first conveying section 51 receives the two workpieces 8 in the upwardly moved state, the delivery section 213 moves downward.

[0034] 5, the inloader 5 moves to a position where the second conveying unit 52 faces the resin tablet supplying device 22 in the vertical direction. The gripping mechanism or suction mechanism of the second conveying unit 52 receives the six resin tablets 9 supplied from the resin tablet supplying device 22.

[0035] Next, as shown in Fig. 6, the inloader 5 moves to a position where the second conveying section 52 faces the delivery section 3111 of the preheating section 311 in the vertical direction. The second conveying section 52 receives the two preheated molded articles 8 from the delivery section 3111 of the preheating section 311. The delivery section 3111 moves upward, for example, to a position where the second conveying section 52 can receive the two preheated molded articles 8. When the gripping mechanism or suction mechanism of the second conveying section 52 receives the two preheated molded articles 8 while in the upward movement state, the delivery section 3111 moves downward.

[0036] Next, as shown in FIG. 7, the inloader 5 moves to a position where the first conveying section 51 faces the delivery section 3111 of the preheating section 311 in the vertical direction, and the second conveying section 52 faces the resin sealing mold 321 in the front-rear direction.

[0037] The first conveying section 51 supplies the two molding workpieces 8 before preheating received from the delivery section 213 of the molding workpiece supply device 21 to the delivery section 3111 of the preheating section 311. The delivery section 3111 moves upward, for example, to a position where it can receive the two molding workpieces 8 from the first conveying section 51. After receiving the two molding workpieces 8 before preheating from the first conveying section 51 while moving upward, the delivery section 3111 moves downward.

[0038] 8, the second conveying section 52 moves the gripping mechanism 523 by the moving mechanism 522 provided in the main body 521 of the second conveying section 52 to move the two molded products 8 and the six resin tablets 9 to a position facing the resin sealing die 32 in the vertical direction. In this state, the two molded products 8 and the six resin tablets 9 are delivered from the second conveying section 52 to the resin sealing die 321. For example, the lower die of the resin sealing die 321 moves upward to a position where it can receive the two preheated molded products 8 and the six resin tablets 9 from the second conveying section 52. The lower die of the resin sealing die 32 moves downward after receiving the two preheated molded products 8 and the six resin tablets 9 from the gripping mechanism 523 of the second conveying section 52 in the upward state.

[0039] After the second conveying section 52 supplies the two preheated molded articles 8 and the six resin tablets 9 to the resin sealing mold 321, as shown in Fig. 9, the moving mechanism 522 moves the gripping mechanism 523 and stores the gripping mechanism 523 in the main body 521 of the second conveying section 52. As described above, the second conveying section 52 may have a suction mechanism instead of the gripping mechanism 523, and in this case, the moving mechanism 522 moves the suction mechanism.

[0040] In this way, the delivery section 3111 of the preheating section 311 is disposed in a position where the first conveying section 51 can supply the two molded articles 8 before preheating when the second conveying section 52 is in a position to supply the two preheated molded articles 8 to the resin sealing mold 321. Therefore, the inloader 5 can perform the operation of supplying the two preheated molded articles 8 to the resin sealing mold 321 and the operation of supplying the two molded articles 8 before preheating to the delivery section 3111 in parallel, and can efficiently convey the members to be resin sealed.

[0041] Similarly, when the second conveying section 52 is in a position to supply the two preheated molded articles 8 to the resin sealing mold 322, the delivery section 3112 of the preheating section 312 is disposed at a position where the first conveying section 51 can supply the two preheated molded articles 8. When the second conveying section 52 is in a position to supply the two preheated molded articles 8 to the resin sealing mold 323, the delivery section 3113 of the preheating section 313 is disposed at a position where the first conveying section 51 can supply the two preheated molded articles 8. When the second conveying section 52 is in a position to supply the two preheated molded articles 8 to the resin sealing mold 324, the delivery section 3114 of the preheating section 314 is disposed at a position where the first conveying section 51 can supply the two preheated molded articles 8.

[0042] 10, the inloader 5 moves to a position where the first conveying section 51 faces the delivery section 213 of the workpiece supply device 21 in the vertical direction, and receives the two workpieces 8 from the delivery section 213 of the workpiece supply device 21 to be supplied to the delivery section 3112 of the preheating section 312. After that, the inloader 5 receives six resin tablets 9 from the resin tablet supply device 22, receives the two preheated workpieces 8 from the delivery section 3112, supplies the two preheated workpieces 8 to the resin sealing mold 322, and supplies the six resin tablets 9 and the two workpieces 8 before preheating to the delivery section 3112 in parallel.

[0043] Similarly, the inloader 5 receives two molded articles 8 from the receiving / transferring section 213, receives six resin tablets 9 from the resin tablet supplying device 22, receives two preheated molded articles 8 from the receiving / transferring section 3113, supplies the two preheated molded articles 8 and six resin tablets 9 to the resin sealing mold 323, and simultaneously supplies the two molded articles 8 before preheating to the receiving / transferring section 3113.

[0044] Similarly, the inloader 5 receives two molded articles 8 from the receiving / transfer section 213, receives six resin tablets 9 from the resin tablet supplying device 22, receives two preheated molded articles 8 from the receiving / transfer section 3114, supplies the two preheated molded articles 8 and six resin tablets 9 to the resin sealing mold 324, and simultaneously supplies the two molded articles 8 before preheating to the receiving / transfer section 3114.

[0045] In this way, since the inloader 5 has the first conveying section 51 and the second conveying section 52, the transfer of the two molded articles 8 between the delivery section 311 and the supply of the two molded articles 8 to the resin sealing die 32 can be performed simply by moving in one direction. Therefore, the members to be resin sealed can be efficiently transported.

[0046] In addition, the inloader 5 may have the first conveying section 51 and the second conveying section 52 as separate bodies. That is, the first conveying section 51 and the second conveying section 52 may be configured to move independently of each other. Even in this case, the first conveying section 51 and the second conveying section 52 can efficiently convey the member to be encapsulated by the above-mentioned operation. Also, the first conveying section 51 and the second conveying section 52 may perform an operation different from the above-mentioned operation under the control of the control device 50 as long as they operate to efficiently convey the member to be encapsulated. Also, as shown in FIG. 1, each of the multiple preheating sections 311, 312, 313, and 314 is disposed such that the distance between the center positions of the corresponding resin encapsulation molds among the multiple resin encapsulation molds 321, 322, 323, and 324 is a distance B in the left-right direction. This distance B should be at least larger than the distance A between the respective center positions of the first transport section 51 and the second transport section 52 when the first transport section 51 and the second transport section 52 approach each other.

[0047] In the above example, the number of molding pieces 8 simultaneously transported by each of the first transport unit 51 and the second transport unit 52 is two, but it may be one or three or more. In the above example, the number of resin tablets 9 simultaneously transported by the second transport unit 52 is six, but it may be five or less or seven or more.

[0048] In the above example, the number of the resin sealing molds 32 is four, but may be three or less, or may be five or more. In the above example, the number of the preheating units 31 is four, but may be three or less, or may be five or more.

[0049] Although the above-mentioned control device 50 is configured as an integrated control device, it may be configured as a plurality of distributed control devices. For example, the control device 50 may be configured to have five control devices that respectively control the component supply unit 2, the resin sealing unit 3, the output unit 4, the inloader 5, and the outloader 6.

[0050] In the above example, the inloader 5 needs to move in order to receive the resin tablet 9 from the resin tablet supplying device 22 after receiving the molded product 8 from the delivery section 213 of the molded product supplying device 21, but is not limited to such an example. For example, the delivery section 213 of the molded product supplying device 21 and the resin tablet supplying device 22 may be disposed at positions where the first conveying section 51 can receive the molded product 8 and the second conveying section 52 can receive the resin tablet 9 simultaneously.

[0051] Furthermore, the resin sealing apparatus 1 may have a configuration in which, instead of the preheating section 31, other processing is performed on the molded article 8 and the treated molded article 8 can be transferred. Furthermore, in addition to the preheating section 31, the resin sealing apparatus 1 may have a configuration in which, in addition to the preheating section 31, other processing is performed on the molded article 8 and the treated molded article 8 can be transferred.

[0052] As described above, the resin sealing apparatus 1 according to the embodiment includes the first conveying section 51 and the second conveying section 52. The first conveying section 51 conveys the molded article 8 before preheating. The molded article 8 before preheating is an example of a first member to be resin-sealed. The second conveying section 52 has a common moving path with the first conveying section 51 and conveys the preheated molded article 8 to be resin-sealed. The preheated molded article 8 is an example of a second member to be resin-sealed. The first conveying section 51 receives the molded article 8 before preheating from the delivery section 213 of the molded article supplying device 21. The delivery section 213 is an example of a first delivery section. The second conveying section 52 receives the preheated molded article 8 from the delivery section 311. The delivery section 311 is an example of a second delivery section and is located at a position different from the delivery section 213. In this manner, since the resin sealing apparatus 1 includes the first transport section 51 and the second transport section 52, the members to be sealed with resin can be efficiently transported.

[0053] Furthermore, the first conveying section 51 supplies the molded article 8 before preheating to the delivery section 311, and the second conveying section 52 supplies the preheated molded article 8 to the resin sealing mold 32. The resin sealing mold 32 is an example of a third delivery section, and is located at a position different from the delivery section 311 and the delivery section 213. The molded article 8 before preheating is heated in the delivery section 311, and is received by the second conveying section 52 from the delivery section 311 as the preheated molded article 8.

[0054] Furthermore, when the second conveying section 52 is in a position to supply the preheated molded article 8 to the resin sealing mold 32, the delivery section 311 is disposed in a position where the first conveying section 51 can supply the preheated molded article 8. This allows the inloader 5 to simultaneously perform the operation of supplying the preheated molded article 8 to the resin sealing mold 32 and the operation of supplying the preheated molded article 8 to the delivery section 311, thereby enabling efficient transport of the member to be resin sealed.

[0055] In addition, the first conveying unit 51 and the second conveying unit 52 are integrated. This eliminates the need for separate drive sources for moving the rails 7 for the first conveying unit 51 and the second conveying unit 52, and makes it possible to avoid the structure of the inloader 5 becoming complicated. In addition, the design can be made easier than when the first conveying unit 51 and the second conveying unit 52 are moved separately.

[0056] Moreover, the delivery section 311 is provided in the preheating section 31 which preheats the molded article 8. Therefore, when the delivery section 311 of the preheating section 31 which preheats the molded article 8 is provided between the delivery section 213 of the member supply unit 2 and the resin sealing mold 32, the member to be resin sealed can be transported efficiently.

[0057] Moreover, the resin sealing apparatus 1 has a plurality of delivery sections 311, which are arranged along a common moving path for the first conveying section 51 and the second conveying section 52. Therefore, in the resin sealing apparatus 1 having a plurality of preheating sections 31, the first conveying section 51 and the second conveying section 52 can deliver the molded article 8 at the plurality of delivery sections 311, and the member to be resin sealed can be efficiently conveyed.
