Description

  The present invention stably stores liquid resin used for resin-sealing electronic components such as transistors, integrated circuits (ICs), and light emitting diodes (LEDs). The present invention relates to a resin molding apparatus and a resin molding method that can be performed. In the present application document, the term “liquid” means that it is liquid at room temperature and has fluidity, regardless of the degree of fluidity, in other words, the degree of viscosity.

  Conventionally, an optical element such as an LED is resin-sealed using a liquid resin that is thermosetting and transmits light, such as a silicone resin or an epoxy resin. As a resin sealing technique, a resin molding technique such as compression molding or transfer molding is used. In resin molding, a liquid resin as a main agent is mixed with a liquid resin as an auxiliary agent such as a curing agent, and the mixed liquid resin is cured by heating. Hereinafter, the liquid resin as the main agent is referred to as “main agent”, and the liquid resin produced by mixing the main agent and the curing agent is referred to as “mixed liquid resin”.

  In a resin molding apparatus using a liquid resin, two kinds of liquid resins (hereinafter referred to as “two liquids”) composed of a main agent and a curing agent are mixed when actually used to produce a mixed liquid resin. There are two-liquid mixing type apparatuses that use liquid resins, and one-liquid type apparatuses that use mixed liquid resins that have been mixed in advance with a main agent and a curing agent. Depending on the product and application, a two-component mixed type device or a one-component type device is used. The two-component mixing type apparatus includes a container filled with a main agent and a container filled with a curing agent. The main agent and the curing agent are stored in separate containers at room temperature, and the two liquids are mixed in a mixing container or the like when actually used. The mixing ratio of the main agent and the curing agent is adjusted according to the object to be molded, and the viscosity of the mixed liquid resin is optimized. In the one-liquid type apparatus, a mixed liquid resin that has been mixed in advance and produced into one liquid is filled in a container, and the mixed liquid resin is used.

  In LED resin sealing, a phosphor, a light diffusing agent, or the like is added as an additive to a liquid resin serving as a main agent in accordance with LED characteristics. The phosphor or light diffusing agent is a crystal, and does not dissolve in the liquid resin, but precipitates in the liquid resin over time. In the case of using either a two-component mixed type device or a one-component type device, the phosphor and the light diffusing agent added to the liquid resin are precipitated. When the phosphor and the light diffusing agent are precipitated, the viscosity and specific gravity of the liquid resin are changed to cause variation. In order to stably store the liquid resin, it is important to keep the phosphor and the light diffusing agent flowing in the liquid resin by a method such as stirring so as to maintain a uniform state.

  As a raw material mixing device that mixes a plurality of raw materials, “In a raw material mixing device that has a plurality of measuring containers and discharges each amount of raw materials from each measuring container at the same time, Stroke amount setting means for setting the amount to be variable; movement amount detection means for detecting (approximately) the movement amount of the piston; and (approximately) the movement amount of the piston detected by the movement amount detection means is a predetermined target value. And a control means for controlling the moving speed of the piston so as to be close to the “raw material mixing apparatus” (for example, refer to paragraph [0005] of FIG. 1 and FIG. 1).

  Hereinafter, in each Example, the case where resin sealing an LED chip is demonstrated. When the LED chip is resin-sealed, a thermosetting silicone resin or an epoxy resin is used as the liquid resin. A phosphor is added to the liquid resin in order to create a color that the LED emits light. The phosphor is powder (powder crystal) and does not dissolve in the liquid resin. Therefore, the phosphor floats in the liquid resin and precipitates in the container with the passage of time.

  As shown in FIG. 1, a supply mechanism 1 that supplies a mixed liquid resin includes a liquid resin storage mechanism 2 that stores the liquid resin, and a dispenser 3 that is a discharge mechanism that discharges the mixed liquid resin. The liquid resin storage mechanism 2 includes a cartridge 4 that stores the liquid resin. The liquid resin storage mechanism 2 is provided with a required number of cartridges 4 according to the type of liquid resin to be used and the production amount.

  The liquid resin includes a liquid resin as a main agent, a liquid resin as a curing agent, a mixed liquid resin produced by mixing the main agent and the curing agent in advance, and a liquid resin as a main agent to which additives such as phosphors are added. A mixed liquid resin to which an additive such as a phosphor is added is stored in the cartridge 4 according to the application. Therefore, the term “liquid resin” refers to a liquid resin in any of these states.

  FIG. 1 shows a case in which a mixed liquid resin 6 produced by mixing a main agent to which an additive such as a phosphor 5 has been added in advance and a curing agent into one liquid is stored in the cartridge 4. The phosphor 5 is a powdery crystal and does not dissolve in the mixed liquid resin 6. Therefore, the phosphor 5 floats in the mixed liquid resin 6 and settles in the cartridge 4 with time. A plunger 7 for pressing and feeding the mixed liquid resin 6 is provided in the cartridge 4. The cartridge 4 and the dispenser 3 are connected by a fluororesin tube 8 that is a pipe. The fluororesin tube 8 preferably has pressure resistance, heat resistance, flexibility, and the like.

  The dispenser 3 shown in FIG. 1 is a so-called one-component dispenser that uses a mixed liquid resin. The one-liquid type dispenser 3 is fed with a storage unit 9 for storing the mixed liquid resin 6 transferred from the cartridge 4, and a metering delivery mechanism 10 for measuring and sending the stored mixed liquid resin 6 by a predetermined amount. The static mixer 11 that is a static mixing member that stirs the mixed liquid resin 6 and the nozzle 12 that is a discharge unit that discharges the mixed liquid resin 6 are connected and integrated.

  As the metering delivery mechanism 10, for example, a combination of a servo motor and a ball screw can be used. The delivery amount of the mixed liquid resin 6 to be delivered can be accurately controlled by the rotation speed of the servo motor. In addition to the servo motor, a combination of a stepping motor and a ball screw, a uniaxial eccentric screw system, an air cylinder or other delivery means can be used.

  At least one of the cartridge 4 for storing the mixed liquid resin 6 to which the phosphor 5 is added, the storage unit 9 provided in the dispenser 3, and the static mixer 11 includes an agitation mechanism MOV ( A portion schematically shown by a dotted line in the figure) is provided. For example, as the stirring mechanism MOV, a vibration mechanism that applies vibration to the mixed liquid resin 6 to which the phosphor 5 is added, a swing mechanism that swings the mixed liquid resin 6, or the like is used. About the stirring mechanism MOV, the same thing can be used also in each Example mentioned later.

  The compressor 13 is a pressurizing mechanism that generates compressed air for pressurizing the mixed liquid resin 6 via the plunger 7. The compressor 13 and the cartridge 4 are connected by a nylon tube 14. The nylon tube 14 preferably has flexibility. Compressed air is supplied from the compressor 13 through the nylon tube 14 to the cartridge 4. An electropneumatic regulator 15 that controls the pressure of the compressed air is provided between the compressor 13 and the cartridge 4.

  Hereinafter, an operation in which the supply mechanism 1 supplies the mixed liquid resin 6 will be described. First, compressed air is supplied to the cartridge 4 from the compressor 13 through the nylon tube 14 and the electropneumatic regulator 15 in order. The plunger 7 is pressed using the compressed air supplied into the cartridge 4. The pressed plunger 7 descends and presses the mixed liquid resin 6 to which the phosphor 5 is added. Thus, the mixed liquid resin 6 is transferred to the storage portion 9 provided in the dispenser 3 via the fluororesin tube 8.

  The mixed liquid resin 6 transferred to the storage unit 9 is sent to the static mixer 11 using the metering delivery mechanism 10. The mixed liquid resin 6 to which the phosphor 5 is added is stirred using the static mixer 11. A mixed liquid resin 6 serving as a raw material resin is discharged from a nozzle 12 provided at the tip of the dispenser 3.

  According to the present embodiment, the stirring mechanism MOV is provided in the cartridge 4 for storing the mixed liquid resin 6 to which the phosphor 5 is added, the storage section for the mixed liquid resin 6 provided in the dispenser 3, and the static mixer 11. be able to. By providing the stirring mechanism MOV, the mixed liquid resin 6 to which the phosphor 5 is added can be flowed. Since the mixed liquid resin 6 flows, the phosphor 5 added to the mixed liquid resin 6 flows together with the mixed liquid resin 6. Therefore, it can prevent that the fluorescent substance 5 precipitates. Since the phosphor 5 can be prevented from precipitating, it is possible to prevent variations in the specific gravity and viscosity of the mixed liquid resin 6 to which the phosphor 5 is added.

  As the stirring mechanism MOV, a vibration mechanism using resonance, ultrasonic waves, a piezoelectric element, or the like can be used. A vibration mechanism can be provided around the cartridge 4, the reservoir 9 provided in the dispenser 3, and the static mixer 11. Of the cartridge 4, the reservoir 9 of the dispenser 3, and the static mixer 11, a component that provides a vibration mechanism may be selected as necessary. By the vibration mechanism, vibration is given to the mixed liquid resin 6 to which the phosphor 5 is added. By applying vibration, the phosphor 5 added to the mixed liquid resin 6 flows in the mixed liquid resin 6. Therefore, it can prevent that the fluorescent substance 5 precipitates.

  Further, as the stirring mechanism MOV, a mechanism for swinging the mixed liquid resin 6 can be used. For example, a mechanism for rotating the storage unit 9 provided in the cartridge 4 or the dispenser 3 can be provided as the swinging mechanism. By rotating the cartridge 4 or the storage unit 9, the mixed liquid resin 6 stored therein flows. Since the mixed liquid resin 6 flows, the phosphor 5 added to the mixed liquid resin 6 flows together with the mixed liquid resin 6. Therefore, the phosphor 5 can be prevented from being precipitated in the cartridge 4 or the storage unit 9.

  Further, as the stirring mechanism MOV, a movable member that moves inside the cartridge 4 or the storage unit 9 can be provided. For example, like a magnetic stirrer, a stirrer in which a bar magnet is sealed with a fluororesin is accommodated or inserted into the cartridge 4 or the storage unit 9. The stirrer is rotated from the outside using magnetic force. Thereby, the mixed liquid resin 6 is stirred, and the phosphor 5 added to the mixed liquid resin 6 is also stirred together with the mixed liquid resin 6. Therefore, the phosphor 5 can be prevented from being precipitated in the cartridge 4 or the storage unit 9.

  Embodiment 2 of a supply mechanism for supplying a mixed liquid resin according to the present invention will be described with reference to FIG. The difference from the first embodiment is that two cartridges are provided as the liquid resin storage mechanism 2. The mixed liquid resin 6 to which the phosphor 5 is added is stored in the two cartridges 4A and 4B. Since the configuration of the two cartridges 4A and 4B and the dispenser 3 is the same as that of the first embodiment, the description thereof is omitted. In the liquid resin storage mechanism 2 and the dispenser 3, the same components will be described with reference numerals such as A, B, C, and D as appropriate.

  As shown in FIG. 2, the liquid resin storage mechanism 2 includes two cartridges 4A and 4B and a connecting portion 16A that connects the cartridges 4A and 4B. The connecting portion 16A includes supply ports 17A and 17B that receive the mixed liquid resin 6 delivered from the cartridges 4A and 4B, and a delivery port 18A that transfers the mixed liquid resin 6 supplied into the connecting portion 16A to the dispenser 3. Prepare. Static mixers 19A and 19B, which are static mixing members for stirring the mixed liquid resin 6 delivered from the cartridges 4A and 4B, are provided inside the connecting portion 16A. The static mixers 19A and 19B are provided from the vicinity of the supply ports 17A and 17B toward the delivery port 18A. Depending on the viscosity of the mixed liquid resin 6, the number of elements of the static mixers 19A and 19B is optimized. Further, depending on the viscosity of the mixed liquid resin 6, the static mixers 19A and 19B may not be provided.

  The delivery port 18A of the connecting part 16A is connected to the storage part 9 of the dispenser 3 by a fluororesin tube 8A. The mixed liquid resin 6 is transferred from the cartridges 4A and 4B to the storage portion 9 of the dispenser 3 via the connecting portion 16A and the fluororesin tube 8A sequentially. In the connecting portion 16A, the opening and closing of the supply ports 17A and 17B and the outlet 18A is controlled by an on-off valve (not shown).

  Cartridges 4A and 4B for storing the mixed liquid resin 6 to which the phosphor 5 is added, a connecting portion 16A for connecting the cartridges 4A and 4B, a reservoir 9 for the mixed liquid resin 6 provided in the dispenser 3, and static At least one of the mixers 11 can be provided with a stirring mechanism MOV (portion schematically shown by a dotted line in the figure) for stirring the mixed liquid resin 6.

  Similarly to the first embodiment, the cartridges 4 </ b> A and 4 </ b> B and the compressor 13 are connected by a nylon tube 14. Compressed air is supplied from the compressor 13 to one of the two cartridges 4A and 4B using a switching valve (not shown). FIG. 2 shows a case where two cartridges 4A and 4B are provided. Three or more cartridges may be provided.

  Hereinafter, the operation for preventing the phosphor 5 added to the mixed liquid resin 6 from being precipitated in the mixed liquid resin 6 in the liquid resin storage mechanism 2 according to the present invention will be described. First, in the connecting portion 16A, an opening / closing valve (not shown) is used to open the supply ports 17A and 17B with the delivery port 18A closed. Next, for example, compressed air is supplied from the compressor 13 to the cartridge 4A. Using the compressed air supplied to the cartridge 4A, the plunger 7A is pressed. The pressed plunger 7A descends to press the mixed liquid resin 6 to which the phosphor 5 is added, and sends the mixed liquid resin 6 into the connecting portion 16A from the supply port 17A. The delivered mixed liquid resin 6 is sequentially stirred by static mixers 19A and 19B provided in the connecting portion 16A. The phosphor 5 is caused to flow together with the mixed liquid resin 6 by stirring. The stirred mixed liquid resin 6 is injected into the cartridge 4B from the supply port 17B. The injected mixed liquid resin 6 and the mixed liquid resin 6 stored in the cartridge 4B are merged.

  Next, the supply destination of the compressed air supplied from the compressor 13 is switched from the cartridge 4A to the cartridge 4B using a switching valve. The compressed air supplied to the cartridge 4B is used to press the plunger 7B, and the mixed liquid resin 6 to which the phosphor 5 joined in the cartridge 4B is added is sent from the supply port 17B into the connecting portion 16A. The sent mixed liquid resin 6 is sequentially stirred by static mixers 19B and 19A provided in the connecting portion 16A. The phosphor 5 is caused to flow together with the mixed liquid resin 6 by stirring. The stirred mixed liquid resin 6 is injected into the cartridge 4A from the supply port 17A. The injected mixed liquid resin 6 and the mixed liquid resin 6 remaining in the cartridge 4A are merged.

  Next, the supply destination of the compressed air supplied from the compressor 13 is switched from the cartridge 4B to the cartridge 4A using a switching valve. The compressed air supplied to the cartridge 4A is used to press the plunger 7A, and the mixed liquid resin 6 merged in the cartridge 4A is sent again from the supply port 17A into the connecting portion 16A. By repeating such an operation, the mixed liquid resin 6 to which the phosphor 5 is added flows between the cartridge 4A and the cartridge 4B via the connecting portion 16A. The mixed liquid resin 6 flowing in the connecting portion 16A is stirred by the static mixers 19A and 19B provided in the connecting portion 16A. In this way, the phosphor 5 added to the mixed liquid resin 6 is caused to flow and further stirred to prevent the phosphor 5 from being precipitated. Therefore, even when the phosphor 5 is added, the mixed liquid resin 6 can be stored in each cartridge 4A, 4B in a uniform state.

  Next, the operation of transferring the mixed liquid resin 6 from the liquid resin storage mechanism 2 to the dispenser 3 will be described. First, in the connecting portion 16A, for example, the supply port 17A and the delivery port 18A are opened while the supply port 17B is closed using an on-off valve (not shown). Next, compressed air is supplied from the compressor 13 to the cartridge 4A. Using the supplied compressed air, the plunger 7A is pressed, and the mixed liquid resin 6 to which the phosphor 5 is added is sent from the supply port 17A into the connecting portion 16A. The mixed liquid resin 6 delivered from the cartridge 4A is stirred by a static mixer 19A provided in the connecting portion 16A. The phosphor 5 is caused to flow together with the mixed liquid resin 6 by stirring. The stirred mixed liquid resin 6 is transferred from the outlet 18A of the connecting portion 16A to the storage portion 9 of the dispenser 3 via the fluororesin tube 8A.

  In the connecting portion 16A, the supply port 17B and the delivery port 18A may be opened with the supply port 17A closed, and the mixed liquid resin 6 stored in the cartridge 4B may be transferred to the dispenser 3. Furthermore, the supply port 17A, the supply port 17B, and the delivery port 18A are all opened, and compressed air can be supplied to both the cartridges 4A and 4B to transfer the mixed liquid resin 6 to the dispenser 3.

  According to the present embodiment, the liquid resin storage mechanism 2 includes the plurality of cartridges 4A and 4B and the connecting portion 16A that connects the cartridges. The plurality of cartridges 4A and 4B are connected by the connecting portion 16A. Thereby, between each cartridge 4A, 4B, the mixed liquid resin 6 with which the fluorescent substance 5 was added can be made to flow mutually via the connection part 16A. The phosphor 5 is caused to flow together with the mixed liquid resin 6 by flowing the mixed liquid resin 6 between the cartridges 4A and 4B. This can prevent the phosphor 5 from being precipitated. Therefore, it is possible to prevent variation in specific gravity and viscosity of the mixed liquid resin 6.

  Further, the static mixers 19A and 19B can be provided inside the connecting portion 16A. The mixed liquid resin 6 flowing between the cartridges 4A and 4B is stirred by the static mixers 19A and 19B. By stirring the mixed liquid resin 6 to which the phosphor 5 is added, the phosphor 5 is caused to flow together with the mixed liquid resin 6. This can prevent the phosphor 5 from being precipitated. Therefore, it is possible to prevent variation in specific gravity and viscosity of the mixed liquid resin 6.

  Further, the pressure of the compressed air supplied from the compressor 13 can be controlled using the electropneumatic regulator 15. By controlling the pressure of the compressed air, the delivery amount and delivery speed of the mixed liquid resin 6 delivered from each cartridge 4A, 4B can be controlled according to the viscosity of the mixed liquid resin 6. Furthermore, the pressure of compressed air can be controlled in multiple stages, and the delivery amount and delivery speed of the mixed liquid resin 6 can be controlled more accurately. By controlling the pressure of the compressed air in this way, the mixed liquid resin 6 can be stably transferred to the storage portion 9 of the dispenser 3.

  Further, the cartridges 4A and 4B for storing the mixed liquid resin 6 to which the phosphor 5 is added, the connecting portion 16A for connecting the cartridges 4A and 4B, the storage portion 9 for the mixed liquid resin 6 provided in the dispenser 3, and At least one of the static mixers 11 can be provided with a stirring mechanism MOV for stirring the mixed liquid resin 6. By providing the stirring mechanism MOV, the mixed liquid resin 6 can be stirred. Since the mixed liquid resin 6 is stirred, the phosphor 5 added to the mixed liquid resin 6 flows together with the mixed liquid resin 6. Therefore, it can prevent that the fluorescent substance 5 precipitates. Since the phosphor 5 can be prevented from precipitating, it is possible to prevent variations in the specific gravity and viscosity of the mixed liquid resin 6 to which the phosphor 5 is added.

  Embodiment 3 of a supply mechanism for supplying a mixed liquid resin according to the present invention will be described with reference to FIG. The difference from the second embodiment is that a so-called two-liquid mixing type dispenser 3 is used, which is mixed when a liquid resin as a main agent and a curing agent as an auxiliary agent are actually used. FIG. 3 shows a case where two cartridges for storing the main agent and the curing agent are provided.

  As shown in FIG. 3, the cartridges 4A and 4B store a liquid resin as the main agent 20 to which the phosphor 5 is added. As the liquid resin used as the main agent 20, a silicone resin, an epoxy resin, or the like is used. In the cartridges 4C and 4D, a curing agent 21 serving as an auxiliary agent is stored.

  The cartridges 4A and 4B that store the main agent 20 are connected by a connecting portion 16A. Similarly, the cartridges 4C and 4D that store the curing agent 21 are connected by a connecting portion 16C. The configurations of the cartridges 4A and 4B and the connecting portion 16A and the configurations of the cartridges 4C and 4D and the connecting portion 16C are the same as those in the second embodiment, and the description thereof is omitted. FIG. 3 shows a case where two cartridges for storing the main agent 20 and two cartridges for storing the curing agent 21 are provided. Not limited to this, three or more cartridges may be provided.

  The delivery port 18A of the connecting portion 16A connecting the main agent cartridges 4A and 4B is connected to the main agent storage portion 9A provided in the dispenser 3 by the fluororesin tube 8A. The delivery port 18C of the connecting portion 16C that connects the hardener cartridges 4C and 4D is connected to the hardener storage portion 9C provided in the dispenser 3 by the fluororesin tube 8C.

  Main agent metering mechanism 10A is connected to main agent reservoir 9A. The curing agent metering mechanism 10C is connected to the curing agent reservoir 9C. Both the main agent reservoir 9 </ b> A and the hardener reservoir 9 </ b> C are connected to a common space called the mixing chamber 22.

  A static mixer 11 serving as a mixing member is connected to the mixing chamber 22. The mixing chamber 22 and the static mixer 11 together constitute a mixing unit that mixes the main agent 20 and the curing agent 21. A nozzle 12 that is a discharge unit is attached to the tip of the static mixer 11.

  At least one of the cartridges 4A and 4B for storing the main agent 20 to which the phosphor 5 is added, the connecting portion 16A for connecting the cartridges 4A and 4B, the main agent reservoir 9A provided in the dispenser 3, and the static mixer 11 First, a stirring mechanism MOV can be provided. The main agent 20 can be stirred by providing the stirring mechanism MOV. Since the main agent 20 is agitated, the phosphor 5 added to the main agent 20 flows together with the main agent 20. Therefore, it can prevent that the fluorescent substance 5 precipitates. Since it can prevent that the fluorescent substance 5 precipitates, it can prevent that dispersion | variation generate | occur | produces in the specific gravity, the viscosity, etc. of the main ingredient 20 to which the fluorescent substance 5 was added.

  An operation of mixing the main agent 20 and the curing agent 21 in the two-liquid mixing type dispenser 3 will be described. The main agent 20 to which the phosphor 5 is added is transferred from one of the cartridges 4A and 4B to the main agent storage portion 9A provided in the dispenser 3 through the connecting portion 16A and the fluororesin tube 8A sequentially. . The curing agent 21 is transferred from either one of the cartridges 4C and 4D to the curing agent reservoir 9C provided in the dispenser 3 via the connecting portion 16C and the fluororesin tube 8C in this order.

  Using the metering delivery mechanism 10A, the main agent 20 transferred to the reservoir 9A is delivered from the reservoir 9A to the mixing chamber 22. The curing agent 21 transferred to the storage unit 9C is sent from the storage unit 9C to the mixing chamber 22 using the metering delivery mechanism 10C. In the mixing chamber 22, the main agent 20 and the curing agent 21 are merged. The main agent 20 and the curing agent 21 which have started to be mixed and mixed in the mixing chamber 22 are further mixed using the static mixer 11. As a result, a mixed liquid resin serving as a raw material resin to which the phosphor 5 is added is generated. The mixed liquid resin to which the phosphor 5 is added is discharged from the nozzle 12 of the dispenser 3.

  According to the present embodiment, the outlets 18A and 18C of the connecting portions 16A and 16C are closed except when the main agent 20 and the curing agent 21 are transferred to the dispenser 3. In the connecting portion 16A, the supply ports 17A and 17B connected to the main cartridges 4A and 4B are opened, and the main agent 20 to which the phosphor 5 is added flows between the cartridges 4A and 4B. As a result, the phosphor 5 added to the main agent 20 can flow together with the main agent 20. Therefore, it is possible to prevent variation in the specific gravity and viscosity of the main agent 20 to which the phosphor 5 is added without the phosphor 5 being precipitated in each cartridge 4A, 4B.

  Further, the main agent 20 flowing between the cartridges 4A and 4B is agitated using the static mixers 19A and 19B provided inside the connecting portion 16A. The phosphor 5 is caused to flow together with the main agent 20 by stirring the main agent 20. Therefore, it is possible to prevent the phosphor 5 from precipitating and to prevent variations in the specific gravity and viscosity of the main agent 20 to which the phosphor 5 is added.

  Further, the cartridges 4A and 4B for storing the main agent 20 to which the phosphor 5 is added, the connecting portion 16A for connecting the cartridges 4A and 4B, the main agent storage portion 9A provided in the dispenser 3, and the static mixer 11 At least one can be provided with a stirring mechanism MOV. The main agent 20 can be stirred by providing the stirring mechanism MOV. Since the main agent 20 is agitated, the phosphor 5 added to the main agent 20 flows together with the main agent 20. Therefore, it can prevent that the fluorescent substance 5 precipitates. Since it can prevent that the fluorescent substance 5 precipitates, it can prevent that dispersion | variation generate | occur | produces in the specific gravity, the viscosity, etc. of the main ingredient 20 to which the fluorescent substance 5 was added.

  In FIG. 3, the cartridges 4C and 4D that store the curing agent 21 are also connected by the connecting portion 16C. If an additive that precipitates in the curing agent 21 is included, static mixers 19C and 19D may be provided in the connecting portion 16C. When the additive which precipitates in the curing agent 21 is not included, the connecting portion 16C may not be provided. In this case, the cartridges 4C, 4D and the curing agent storage portion 9C provided in the dispenser 3 are directly connected by the fluororesin tube 8C.

The release film 37 is adsorbed along the mold surface of each individual cavity 44. FIG. 5A shows a case where the film pressing member 42 is used. Not only this but the release film 37 and the film pressing member 42 do not need to be used.

  As shown in FIG. 5B, the supply mechanism 1 is configured by integrating a liquid resin storage mechanism 2 and a dispenser 3. The dispenser 3 shown in FIG. 5 is the one-liquid type dispenser shown in FIG. The liquid resin storage mechanism 2 is provided with cartridges 4A and 4B for storing the mixed liquid resin 6 and a connecting portion 16A for connecting the cartridges 4A and 4B.

Since the phosphor 5 can be prevented from precipitating, it is possible to prevent variations in the specific gravity and viscosity of the mixed liquid resin 6 to which the phosphor 5 is added.

  FIG. 5 shows a case where two cartridges for storing the mixed liquid resin 6 are provided. Not limited to this, three or more cartridges may be provided. All the three or more cartridges are connected to the dispenser 3 through the connecting portion 16A.

  With reference to FIG. 6, Example 5 of the resin molding apparatus based on this invention is demonstrated. The difference from the fourth embodiment is that a two-liquid mixing type dispenser is used as the dispenser 3. The dispenser 3 shown in FIG. 6 is the same as the two-liquid mixing type dispenser shown in FIG. The liquid resin storage mechanism 2 includes a liquid resin storage mechanism 2 </ b> A that stores the main agent 20 and a liquid resin storage mechanism 2 </ b> C that stores the curing agent 21. The supply mechanism 1 is configured by integrating liquid resin storage mechanisms 2A, 2C and a dispenser 3.

  The liquid resin storage mechanism 2A is provided with cartridges 4A and 4B for storing the main agent 20 and a connecting portion 16A for connecting the cartridges 4A and 4B. The phosphor 5 is added to the main agent 20. Each cartridge 4A, 4B is connected to the storage part 9A of the dispenser 3 via the connecting part 16A and the fluororesin tube 8A.

  Similarly, the liquid resin storage mechanism 2C is provided with cartridges 4C and 4D for storing the curing agent 21 and a connecting portion 16C for connecting the cartridges 4C and 4D. Each cartridge 4C, 4D is connected to the storage portion 9C of the dispenser 3 via the connecting portion 16C and the fluororesin tube 8C.

The mixing chamber 22 and the static mixer 11 to be mixed, and the nozzle 12 for discharging the mixed liquid resin 46 mixed are configured integrally. Thus, by integrating the configuration of the dispenser 3, the dispenser 3 can be reduced in size. Since the dispenser 3 can be reduced in size, the supply mechanism 1 in which the dispenser 3 and the liquid resin storage mechanisms 2A and 2C are integrated can be reduced in size.

  The supply mechanism 1 is provided with a moving mechanism 47 that moves the dispenser 3 in the Y direction. Similar to the fourth embodiment, the dispenser 3 can be moved in the vertical direction (Z direction). Further, it can be reciprocated so as to partially rotate around a certain point.

  The static mixer 11 and the nozzle 12 shown in FIG. 6 are attached to and detached from each other. Therefore, the static mixer 11 and the nozzle 12 can be exchanged individually. By exchanging the nozzle 12, the direction in which the mixed liquid resin 46 is discharged can be set to an arbitrary direction such as right below, right next, or diagonally downward.

  Similarly to Example 3, the cartridges 4A and 4B for storing the main agent 20 to which the phosphor 5 is added, the connecting portion 16A for connecting the cartridges 4A and 4B, and the main agent storage portion 9A provided in the dispenser 3 are provided. And at least one of the static mixers 11 can be provided with a stirring mechanism MOV. The main agent 20 can be stirred by the stirring mechanism MOV. The main agent 20 is caused to flow by stirring. Therefore, it can prevent that the fluorescent substance 5 precipitates. Since it can prevent that the fluorescent substance 5 precipitates, it can prevent that dispersion | variation generate | occur | produces in the specific gravity, the viscosity, etc. of the main ingredient 20 to which the fluorescent substance 5 was added.

  FIG. 6 shows a case where two cartridges for storing the main agent 20 and the curing agent 21 are provided. Not limited to this, three or more cartridges may be provided. All the three or more cartridges are connected to the dispenser 3 through the connecting portions 16A and 16C.

Not only this but liquid resin storage mechanism 2 (2A, 2C) and dispenser 3 can also be constituted separately, respectively. In this case, the supply mechanism 1 provided with only the dispenser 3 can be moved along the rail 33.

  In Examples 4 and 5 (see FIGS. 4 to 6), the dispenser 3 itself is disposed along the horizontal direction, in other words, it is disposed sideways. As a result, the height of the resin molding device 23 can be reduced. The dispenser 3 itself may be arranged along the vertical direction, in other words, vertically. Thereby, the plane area of the resin molding apparatus 23 can be reduced. In addition, the dispenser 3 itself may be disposed obliquely downward.

  In Examples 4 and 5 (see FIGS. 4 to 6), four molding modules 25A, 25B, 25C, and 25D are arranged in the X direction between the substrate supply / storage module 24 and the liquid resin supply module 26. Installed side by side. The substrate supply / storage module 24 and the liquid resin supply module 26 may be combined into one module, and one molding module 25A may be mounted side by side in the X direction. Further, the molding module 25A may be mounted side by side in the X direction on one module, and another molding module 25B may be mounted on the molding module 25A. Therefore, the configuration of the resin molding apparatus 23 can be optimized in accordance with the production form and production volume, and the productivity can be improved.

  In each Example, the case where the fluorescent substance 5 was added as an additive to the mixed liquid resin 6 or the liquid resin as the main agent 20 was shown. The additive is not limited to the phosphor 5 but may be a light diffusing agent or the like. Further, the mixed liquid resin 6 may include a plurality of types of liquid resins that are easily separated. If the additive is granular, fine powder, powder, granule, flake (flaky), lump, etc., and has the property of precipitating in the liquid resin, the present invention has the same effect. .

  In addition, in each Example mentioned above, the resin molding apparatus and the resin molding method used when resin-sealing an LED chip were demonstrated. The target for resin sealing may be a semiconductor chip such as an IC or a transistor, or a passive element. The present invention can be applied when resin-sealing one or a plurality of electronic components mounted on a substrate such as a printed circuit board or a ceramic substrate.

In the case of a reflecting member, a white pigment such as titanium dioxide (TiO ₂ ) is used as an additive.

  In Examples 4 and 5, the resin molding apparatus and the resin molding method by compression molding have been described. In addition, the present invention can be applied to a resin molding apparatus and a resin molding method by transfer molding. In this case, there is a resin storage portion formed of a cylindrical space provided in the mold (a portion where a lifting member called a plunger is disposed below and a columnar resin material usually made of a solid resin is stored. The raw material resin made of the mixed liquid resin is supplied to a pot).

  In Examples 4 and 5, an example in which a cavity provided in the lower mold is used as a housing portion and a raw material resin (hereinafter referred to as “raw resin”) made of a mixed liquid resin is supplied to the cavity is described. In addition to the cavity, the accommodating portion may be any of the following. 1stly, an accommodating part is the pot (above-mentioned) provided in the lower mold | type.

The raw material resin is supplied so as to cover the chip mounted on the upper surface of the substrate. In this case, it is preferable to perform electrical connection between the chip and the substrate by flip chip.

  Third, the accommodating portion is a space including the upper surface of a semiconductor substrate such as a silicon wafer. The raw material resin is supplied so as to cover a functional part such as a semiconductor circuit formed on the semiconductor substrate. In this case, it is preferable that a protruding electrode (bump) is formed on the upper surface of the semiconductor substrate.

  Fourth, the accommodating portion is a space including the upper surface of the film that is to be finally accommodated in the cavity of the mold. The accommodating part in this case is a recessed part formed, for example, when a film is dented. The raw material resin is supplied to the recess formed by the depression of the film. Examples of the purpose of the film include improvement of releasability, transfer of a shape composed of irregularities on the surface of the film, and transfer of a pattern formed in advance on the film.
