Description

  The present invention prevents the misplacement or the like of a replaceable member that is exchanged in a manufacturing apparatus according to the article to be manufactured, thereby maintaining the quality of the article and preventing the manufacturing apparatus from being adversely affected. The present invention relates to an article manufacturing apparatus and a manufacturing method.

  In order to prevent product defects from occurring during the work of exchanging molds that are exchanged according to the type of article processed in a press machine, etc. It is being determined. For example, a barcode tag corresponding to an identification number assigned to a die attached to the press machine main body is attached to a barcode management panel provided in the machine setup unit. At the time of mold setup, the barcode tag corresponding to the identification number of the mounting mold is read by the barcode reader. The unique mold information read by the barcode reader and the set mold information when the mold set is used for processing are stored, and the necessary mold set is based on the set mold information during processing. A mold management method for calling and exchanging molds has been proposed (see paragraphs [0006], [0009], [0027] and FIG. 5 of Patent Document 1).

  A resin sealing device for electronic components, which is a kind of resin molding device, covers a chip-like element such as a semiconductor chip mounted on a substrate (a lead frame, a printed circuit board, etc.) with a sealing resin. Thus, a sealed substrate that is a molded product is completed. The mold for resin sealing in the resin sealing apparatus is replaced when the model (type) of the sealed substrate is changed, when the mold is worn, or the like. Therefore, a shaping | molding die is a replaceable member exchanged according to the kind of articles | goods (sealed board | substrate) manufactured.

  If the mold that has been replaced and is newly installed is not an appropriate mold (for example, if the mold is misinstalled due to an operator's selection error, etc.), the quality is guaranteed and the characteristics match. If a product different from the correct mold (compatible product) is mounted, the quality of the molded product may be impaired. In addition, there is a possibility that problems such as adversely affecting the main body of the resin sealing device may occur.

  When exchanging a mold used by being mounted on a resin sealing device for electronic components, an operator manually performs the exchanging operation. For this reason, a barcode tag cannot be provided in the machine setup part. In addition, when a barcode tag is provided on the mold in order to identify the mold, there are the following problems. After the mold is attached to the resin molding apparatus, it is heated to a predetermined molding temperature (for example, about 180 ° C.) and used in that state. For this reason, when a barcode tag is used as a marker, the barcode tag is easily damaged by a high temperature, and the display function applied to the marker tends to be impaired. Therefore, even if a sign indicating that the barcode tag is compatible is displayed, if the barcode tag is damaged, it is not possible to correctly determine the suitability of the mounted mold. . Therefore, there is a possibility that erroneous mounting of a replaceable member used for manufacturing an article may occur.

  As a method of managing the mold, a method of adding an RFID (Radio Frequency IDentification) tag to each mold part constituting the mold has been proposed (see paragraph [0013] of Patent Document 2). This method is not applicable to molds used at high temperatures (eg, about 180 ° C.). This is because the RFID tag attached to the mold part is destroyed by heat.

The term “compatible product” means that the mold 6 is to be originally used, and specifically has at least the following two meanings. The term “compatible product” first means that the mold 6 is a mold that is compatible with the product to be manufactured and has a guaranteed quality. The term “conforming product” secondly means that the mold 6 is a mold provided by a legitimate manufacturer or supplier.

  As shown in FIG. 2, in the resin sealing device 1, a fine pattern formed on the information forming surface 9 a of the marker 9 attached to the mold 6 at a position corresponding to a predetermined position in the mold 6. An information reading means (information reading unit) 10 is provided for reading.

  As shown in FIG. 1 (1), the control unit 8 includes a decoding unit DE that obtains first information based on a fine pattern formed on the information forming surface 9a read by the information reading unit 10, and a molding unit. A storage unit ME in which information (second information) for specifying the mold 6 is stored in advance is provided. The control unit 8 compares the obtained first information with previously stored second information to determine whether or not the mold 6 is compatible with the second information. Is provided. The control unit 8 controls the operation of the resin sealing device 1 including the operation of the drive mechanism 7 based on the determination result.

  As shown in FIG. 1 (2), the movable mold 5 constituting the mold 6 has a pot 5 a to which a resin material is supplied and a cavity 5 b on the movable mold 5 side (hereinafter referred to as “movable side”). And a movable resin passage 5c connected to the movable cavity 5b, and an air vent 5v. The fixed mold 4 is provided with a resin passage 4a on the fixed mold 4 side (hereinafter referred to as “fixed side”) and a fixed-side cavity 4b.

  The movable mold 5 and the fixed mold 4 are clamped by a mold opening / closing mechanism 7a. In a state where the movable mold 5 and the fixed mold 4 are clamped, the mold surfaces of the movable mold 5 facing each other (upper surface in FIG. 1 (1)) and the mold surface of the fixed mold 4 (lower surface in FIG. 1 (1)). And adhere closely. In this state, the pot 5a of the movable mold 5 communicates with the fixed resin passage (cull portion) 4a, and the fixed resin passage 4a communicates with the movable resin passage 5c. In addition, the pot 5a of the movable mold 5 communicates with the movable side cavity 4b and the fixed side cavity 5b through the resin passage 4a and the resin passage 5c sequentially.

  During resin molding, fluid resin such as molten resin is filled in the movable side cavity 4b and the fixed side cavity 5b. The gas remaining inside the cavity 4b and the cavity 5b is discharged out of the mold 6 through the air vent 5v as the fluid resin is filled.

  As shown in FIG. 2 (1), the information reading means 10 is respectively arranged on the main body 1 of the resin sealing device corresponding to the position where the marker 9 is mounted on each of the fixed mold 4 and the movable mold 5. The Therefore, each information reading means 10 can read a fine pattern from the information forming surface 9a of each marker 9 attached to the fixed mold 4 and the movable mold 5 mounted on the fixed plate 2 and the movable plate 3, respectively. .

  As shown in FIG. 2 (2), the light representing the image on the information forming surface 9a passes through the light guide part (light guide path) La, the convex lens (condenser lens) Lb, and the light guide part Lc. Enter Ld. The image sensor Ld is, for example, a CCD sensor or a CMOS sensor. The image sensor Ld converts light corresponding to the image on the information forming surface 9a into an electrical signal. Image data composed of an electrical signal representing an image of the information forming surface 9a is sent to the control unit 8 (see FIG. 1) via the cable Le. Instead of the combination of the convex lens Lb, the light guide portion Lc, and the image sensor Ld, a digital camera having an image sensor may be disposed as the information reading means 10. This digital camera preferably has heat resistance.

  A molding die 6 composed of a fixed die 4 and a movable die 5 constitutes a set of die units. Therefore, you may fix the label | marker 9 to either the fixed mold | type 4 or the movable mold | type 5 by methods, such as sticking. In this case, the information reading means 10 is arranged on one side of the fixed mold 4 or the movable mold 5 in the resin sealing device 1 so as to correspond to the side of the mold 6 to which the marker 9 is attached. Just keep it. In the following description, the case where the marker 9 is affixed to the stationary mold 4 is targeted.

  As shown in FIG. 3, the thickness of the marker 9 that is adhered to and integrated with the surface of the molding die 6 (at least one of the fixed die 4 and the movable die 5). A recess 4d for labeling is provided so as to be deeper. Therefore, as will be described later, by sticking the sign 9 to the inner bottom surface of the recess 4d and integrating it, the information forming surface 9a of the sign 9 comes into contact with other components and the like, so that the information forming surface 9a Problems such as deformation or damage can be prevented.

  Hereinafter, when the 1st information is applicable product information, the contents which control part 8 controls resin sealing device 1 are described. As will be described later, based on the determination result “whether it is a conforming product” obtained by the discriminating unit J, the control unit 8 obtains information on whether or not the molding die 6 to be identified is a conforming product, Displayed in the resin sealing device 1. Specifically, if the mold 6 is a conforming product, that effect is displayed on the display panel. In addition, it is preferable to shift to a state in which the molding module M including the molding die 6 becomes operable. If the mold 6 is not a compatible product, a message to that effect is displayed on the display panel, and a warning is given to the operator by methods such as lighting, blinking, or generating a warning sound. The molding module M may be shifted to a state where the molding module M becomes inoperable (for example, a state where the power is ON but an operation start signal is not received, a state where the power is turned off, etc.).

  When each of the fixed mold 4 and the movable mold 5 is a so-called divided mold (not shown) configured by dividing into a plurality of bodies, for example, the most important part of the cavity block that can be replaced is marked. 9 is pasted. In this case, it is possible to prevent erroneous mounting on the cavity block which is the most important component in resin molding and which is a replaceable member, mounting of a nonconforming product, and the like.

  FIG. 3 illustrates a laser-type so-called non-contact type code reading sensor as the information reading means 10. The information reading means 10 reflects the laser beam 10b emitted from the laser diode 10a by reciprocating a repetitive vibration mirror (scanning mirror) 10c. As a result, the information forming surface 9a formed on the marker 9 is scanned with the laser beam 10b reflected by the repetitive vibration mirror 10c. The reflected light 10d reflected by the information forming surface 9a from the laser light 10b is received by the photodiode 10e. Thus, the fine pattern formed on the information forming surface 9a is optically read.

  As shown in FIG. 4, a high-precision fine pattern is formed on the information forming surface 9a side (front surface side) of the sign 9 by electroforming (electrocasting). A release paper 9c is attached to the back side of the sign 9 via an adhesive 9b. In the state where the release paper 9c is peeled off, the back surface side of the label 9 is adhered to the inner bottom surface of the label application recess 4d (5d) on the label application surface of the mold 6 through the adhesive 9b. (See FIG. 3).

  The sign 9 is formed into a thin sheet by electroforming. The label 9 has the following two purposes. The first purpose is to avoid discriminating (incorrect recognition) that a nonconforming product is a conforming product. The second purpose is to remove the marker 9 from the marker attaching surface (the inner bottom surface of the marker attaching recesses 4d and 5d) in the molding die 6 (fixed die 4 and movable die 5). Attaching to non-conforming products, etc., so that they cannot be reused. Therefore, the thickness of the marker 9 is set to a thickness that satisfies both of the following two conditions (in other words, a necessary and sufficient thickness). First, at the time of sticking to a conforming product, the shape retention of the sign 9 and the high accuracy and certainty when reading the fine pattern (information represented by) formed on the information forming surface 9a. The thickness that can be maintained. Secondly, the thickness is such that at least the information forming surface 9a is damaged when the label 9 attached to the label attaching surface 4d (5d) is peeled off.

  As the thickness of the label 9 (electroformed product) having the above two conditions, for example, when electroforming is surface transfer, a thickness of 0.05 to 0.1 μm is possible. With this thickness, a fine pattern representing information can be manufactured with high accuracy. Even when the sign 9 having the information forming surface 9a including a three-dimensional shape (three-dimensional shape) is manufactured, it is possible to manufacture an electroformed product having a thickness satisfying the above two conditions by a normal electroforming process. It is.

  Based on FIG. 4, the case where the sign 9 is manufactured will be described. 4 (1) and 4 (2) show the electroforming process, and FIGS. 4 (3) and 4 (4) show the process of integrating the release paper with the adhesive on the back surface of the label 9. Simplified.

  As shown in FIG. 4 (1), in the electroforming process, a constant amount is externally provided between the metal (nickel anode) 22 and the matrix (cathode) 23 in the electrolytic bath 21 in the electroforming tank 20. Apply voltage. As a result, metal ionization occurs at the anode and electrodeposition due to metal reduction occurs in the matrix 23. The electrodeposition shown in FIG. 4 is done with nickel. An electroformed product 24 made of electrodeposited nickel is used as the main body of the marker 9. The mother die 23 is preferably manufactured by precision machining such as elliptical vibration cutting.

  Next, as shown in FIG. 4 (2), the electroformed product 24 electrodeposited on the mother die 23 is peeled off from the mother die 23. A fine pattern is formed on the electroformed product 24 by reversing the high-precision shape or the like formed on the mother die 23. The fine pattern having a highly accurate shape formed in the electroformed product 24 is used as a fine pattern representing information for specifying the mold 6 on the information forming surface 9 a of the marker 9.

  Next, as shown in FIG. 4 (3), the adhesive 9b with the release paper 9c attached is attached to the back surface of the electroformed product 24 (on the surface opposite to the information forming surface 9a). In this way, the label 9 with the adhesive 9b is manufactured.

  Next, as shown in FIG. 4 (4), the release paper 9 c is peeled off from the marker 9. The back surface of the label 9 is attached to the inner bottom surface of the label attaching recess 4d (5d) on the label attaching surface of the mold 6 through the adhesive 9b. As a result, the inner bottom surface of the recess 4d (5d) of the mold 6 and the marker 9 can be integrated.

  The pressure-sensitive adhesive 9b and the release paper 9c are formed in a state where the label 9 is attached to the label-attaching recess 4d (5d) on the label-attachment surface of the molding die 6 with the release paper 9c removed. Used to attach to the bottom and integrate. When directly attaching the electroformed product 24 (the main body of the label 9) to the inner bottom surface of the recess 4d (5d), instead of the adhesive 9b and the release paper 9c, a double-sided adhesive tape is used in advance. You may affix on the inner bottom face of the recess 4d (5d).

  The sign 9 on which the fine pattern representing the conforming product information is formed is, first of all, to indicate that the mold 6 is a mold that conforms to the product to be manufactured and has a guaranteed quality. ,means. Secondly, the label 9 on which the fine pattern representing the conforming product information is formed is such that the molding die 6 is, for example, an authorized producer of the resin sealing device, an authorized mold manufacturer, or an authorized resin sealing device. It means that it is a mold provided by a service provider (hereinafter referred to as a “conforming product provider”) related to regular molds. In the sign 9, the information forming surface 9a on which the fine pattern representing the information specifying the type is formed can be distinguished from a non-conforming product that is not attached with a sign or a sign by a person other than the conforming product provider. Thus, it is formed with high accuracy.

  For example, a barcode, a two-dimensional code, or the like is formed on the information forming surface 9a. In addition to or instead of these, the information forming surface 9a is difficult to imitate characters, character strings, symbols, shapes, three-dimensional shapes, combinations thereof, or imitations arbitrarily determined by the conforming product provider. A fine pattern made of a special image, hologram, or other highly accurate mark may be formed. Based on the fine pattern formed on the information forming surface 9a, information specifying the mold 6 is read. The fine pattern formed on the information forming surface 9a is preferably a pattern that is difficult to imitate. The fine pattern formed on the information forming surface 9a is a fine pattern for displaying a conforming product provider, and a mark such as a symbol having a function of displaying the origin of goods or services, a trademark (including a registered trademark), a logo It may contain a type (logo type).

  Hereinafter, with reference to FIGS. 1 to 3 and the flowchart shown in FIG. 5, the process of identifying the mold 6 (see FIGS. 1 and 2) and determining whether or not the mold 6 is a conforming product. Is described. First, as shown in step S <b> 1 in FIG. 5, in a state where the power of the resin sealing device 1 is turned on, the fixed mold 4 is mounted on the fixed platen 2, and the movable mold 5 is mounted on the movable platen 3. Installing. Mounting of the fixed mold 4 and the movable mold 5 in this step may be temporary placement (temporary fixing) as long as the fine pattern formed on the information forming surface 9a of the marker 9 can be read.

  Next, as shown in step S2, the information reading means 10 is used to form a fine pattern formed on the information forming surface 9a of the sign 9 attached to each of the fixed mold 4 and the movable mold 5 that are mounted. Read.

  Next, as shown as step S3, the control unit 8 obtains first information from the fine pattern formed on the information forming surface 9a. For example, when the fine pattern is a two-dimensional code, the two-dimensional code is decoded.

  Next, as shown as step S <b> 4, the control unit 8 reads out second information (information stored in advance) including information for specifying the mold 6. The second information is stored in advance in the storage unit ME included in the control unit 8 of the resin sealing device 1.

  Next, as shown as step S5, the determination unit J in the control unit 8 includes the first information obtained from the fine pattern formed on the information forming surface 9a of the sign 9 and the second information stored in advance. The information specifying the mold 6 included in the information is compared. Based on the comparison result, the discriminating unit J determines whether “the fixed mold 4 is a“ conforming product ”or not and“ the movable mold 5 is a “conforming product”. Determine.

  In the following, processing in the case where the comparison result is “each of the fixed mold 4 and the movable mold 5 is a conforming product” (first case) will be described. After step S5, as shown in step S6, the determination unit J determines that the fixed signal indicating that the fixed die 4 is “compatible” and “the movable die 5 is“ compatible ”. Is generated.

  Next, as shown in step S7, the control unit 8 displays the “fixed mold 4 on the display unit (touch panel or the like; not shown) of the control unit 8 of the resin sealing device 1 based on the received matching signal. “It is a“ conforming product ”” and “the movable mold 5 is“ a conforming product ”” are displayed. In addition, the control unit 8 may turn on the warning lamp in a mode (for example, a mode in which green light is continuously turned on) indicating that the resin sealing device 1 is operable. At the same time, the control unit 8 may indicate that the resin sealing device 1 is in an operable state by a sound such as “operable”.

  Next, as shown as step S <b> 8, the control unit 8 shifts the resin sealing device 1 to an operable state (operating state) based on the received matching signal. When the resin sealing device 1 is already in an operable state, the control unit 8 continues to maintain the resin sealing device 1 in an operable state. Steps S7 and S8 may be switched in order or may be executed simultaneously.

  In the following, a process when the comparison result is “at least one of the fixed mold 4 and the movable mold 5 is not“ conforming product ”” (second case) will be described. As an example, a process in the case where the fixed mold 4 is “conforming product” and the movable mold 5 is not “conforming product” will be described. After step S5, as shown as step S9, the determination unit J generates a non-conformance signal indicating that the movable mold 5 is not a “conforming product”.

  Next, as shown in step S <b> 10, based on the received nonconformity signal, the control unit 8 displays “the movable mold 5 is“ conforming product ”on the display unit (not shown) of the control unit 8 of the resin sealing device 1. "Not" is displayed. In addition, the control unit 8 may turn on the warning lamp in a mode (for example, a mode in which yellow or red light is intermittently turned on) indicating that the resin sealing device 1 cannot operate. . In addition, the control unit 8 may indicate that the resin sealing device 1 is in an inoperable state by a sound such as a warning sound or “inoperable”.

  Next, as shown as step S <b> 11, the control unit 8 shifts the resin sealing device 1 to an inoperable state (non-operating state) based on the received nonconforming signal. Step S10 and step S11 may be switched in order or may be executed simultaneously. Even when the fixed mold 4 is not a “compatible product” and when both the fixed mold 4 and the movable mold 5 are not “compatible products”, the same process as in the second case described above is performed.

  When at least one of the fixed mold 4 and the movable mold 5 is a type that is not a “conforming product” (hereinafter referred to as “nonconforming type”), the operator will be referred to as a “conforming product” (hereinafter referred to as “conforming type”). .) Is searched from the mold inventory. The operator replaces the nonconforming type with the found compatible type. The operator operates the control unit 8 of the resin sealing device 1 according to the flowchart shown in FIG. 5 in a state where the adaptive mold is temporarily placed on the resin sealing device 1. In this case, since the adaptive mold is temporarily placed in the resin sealing device 1, the resin sealing device 1 shifts to the operation state by performing the processing of steps S1 to S5 to S8.

  So far, it has been described that the information for specifying the mold 6 is included in at least the first information. In addition, so far, the information for specifying the mold 6 includes information on the manufacturer, supplier, and service provider of the mold 6, the model number and serial number of the mold 6, and the mold 6. In addition, it is described that compatible product information indicating that the mold 6 is a compatible product is included. Not limited to these, information specifying the mold 6 includes the date of manufacture, the date of start of use, the date of use, the lot number of the manufactured article (sealed substrate), and the number of times of use. History information indicating a history such as (the number of shots) may be included. The history information may include information indicating the history and the history of the cleaning, inspection, maintenance (maintenance) and replacement (hereinafter referred to as “inspection, maintenance, etc.”) of the mold 6. The history information may include information indicating a history of defects and improvements in the past with respect to the mold 6. Accordingly, the user (user) of the resin sealing device 1 or the mold 6 or a compatible product provider creates a database of such information (information indicating a history of defects, improvements, etc.). Such information is used to improve the operating rate of the resin sealing device 1 or the mold 6.

  A case where the determination unit J (see FIG. 1) determines that it is time to perform inspection, maintenance, and the like on the movable mold 5 based on the history information will be described. In this case, the determination unit J generates a maintenance required signal indicating that “the movable mold 5 is a“ required maintenance product ”that requires inspection, maintenance, and the like”. Based on the received maintenance-required signal, the control unit 8 displays that “the movable mold 5 is a maintenance-required product” and shifts the resin sealing device 1 to an inoperable state (non-operating state). Therefore, the user (user), the operator, and the like of the resin sealing device 1 can know that it is time to perform inspection, maintenance, etc. for the movable mold 5. In addition, it is possible to prevent a situation in which the molding die 6 including the movable die 5 continues to be used after a time when inspection, maintenance, etc. are necessary due to carelessness. The term “maintenance required” described above means that the mold is not a mold that should be used originally from the viewpoint of whether inspection, maintenance, or the like is necessary.

  The information for specifying the mold 6 includes at least compatible product information, and may include history information as necessary. The information for specifying the mold 6 may include any one of conforming product information and history information as necessary.

  Even if the mold 6 is not a compatible product, there may be no problem in using the mold 6. For example, this is a case where the information indicating the conforming product includes the mold 6 manufactured in a specific factory owned by the mold manufacturer. In the case where the mold 6 is manufactured in another factory owned by the mold manufacturer, the mold 6 can be used. Assuming such a case, when the operator confirms the information indicating the conforming product and determines that the mold 6 can be used, a signal input by the operator from the outside of the resin sealing device 1 is used. The determination in the control unit 8 may be changed. Specifically, according to the signal input by the operator, it is only necessary to shift from the determination of “not a conforming product” to the determination of “a conforming product”.

  As shown in FIG. 3, a laser type code reading sensor is exemplified as the information reading unit 10. The information reading means 10 is not limited to such means. For example, image data obtained by photographing the information forming surface 9a of the marker 9 may be sent to the control unit 8 by using an image sensor such as a CCD element (Charge Coupled Device) which is an image reading sensor. The sent image data may be compared with specific image data (reference data) stored in advance to determine whether or not it is a conforming product. A CMOS sensor can also be used as the image reading sensor. The information reading means 10 only needs to be capable of reading the fine pattern formed on the information forming surface 9a of the sign 9 with high accuracy and accuracy.

  The present embodiment has a useful and remarkable effect described below. First, the first information read from the mark 9 fixed to the molding die 6 and the first information stored in advance are used to determine whether or not the molding die 6 that is a replaceable member is a compatible product. Two pieces of information are used. The first information includes information for specifying the mold 6, and the second information includes at least information for specifying the mold 6. The information specifying the mold 6 includes at least one of conforming product information and history information, and preferably includes both of them. By these things, it can be discriminate | determined first whether the shaping | molding die 6 which is a replaceable member is a compatible product. Second, it is possible to determine whether or not the mold 6 that is a replaceable member is a maintenance object.

  Second, since the sign 9 is manufactured by electroforming, a fine pattern can be formed on the information forming surface 9a of the sign 9 with high accuracy. In addition, the label 9 has heat resistance. By these, the optimal label | marker 9 for sticking and using to the shaping | molding die 6 mounted in the resin molding apparatus containing the resin sealing apparatus of an electronic component is obtained. Therefore, since the molding die 6 to which the label 9 is attached can be used, it is possible to prevent erroneous mounting of the molding die 6 by an operator.

  Thirdly, by using the mold 6 to which the marker 9 is attached, the quality of the molded product is deteriorated, and the resin sealing device 1 is adversely affected, deteriorated in durability, and has other adverse effects. You can prevent problems.

  Fourth, since the marker 9 is formed into a thin sheet, the marker 9 is broken when the marker 9 is peeled off from the mold. Due to this, the label 9 cannot be peeled off and reattached to another mold in the original state. Therefore, for example, it is possible to prevent unauthorized use of the sign 9 by a person other than the conforming product provider, supply of a molding die that is a nonconforming product, and the like.

On the basis of this, the conforming product provider alerts the user of the resin sealing device 1 or the mold 6 that the time for inspection, maintenance, etc. has come. The compatible product provider may inform the user that he / she is ready to dispatch a service engineer of the compatible product provider or to supply a replacement member for replacement as necessary. The server of the conformity product provider confirms that the time for inspection, maintenance, etc. is near, that it is ready to dispatch a service engineer, and that it is ready to supply replacement parts for replacement. It may be automatically transmitted to one control unit 8 or to a server owned by a user of the resin sealing device 1. As a result, information for ensuring preventive maintenance and regular maintenance is provided to both the conforming product provider and the user regarding the resin sealing device 1 or the mold 6.

  The light representing the fine pattern image formed on the information forming surface 9a enters the convex lens 37 through the light guide portion 45 consisting of a space and is condensed. The collected light is reflected by the reflecting mirror 38. The light reflected by the reflecting mirror 38 enters the image sensor 40 via the light guide unit 46 made up of space, and is converted into image data made up of electrical signals. The converted image data is sent to the camera controller 43 included in the control unit 8 (see FIG. 1) via the cable 42. In the present embodiment, at least the light receiving unit 36 having the convex lens 37 and the reflecting mirror 38, the light guiding unit 46, and the image acquiring unit 41 having the image sensor 40 are included in the information reading unit 10 shown in FIG. It has a function corresponding to. At least the light receiving unit 36, the light guide unit 46, and the image acquisition unit 41 are included in the information reading unit 10.

  According to the present embodiment, the following effects can be obtained. First, since it is automatically determined whether or not the mold 6 that is a replaceable member is a compatible product, erroneous mounting of the mold 6 can be prevented. This effect is obtained by automatically reading information identifying the mold 6 from the information forming surface 9a of the mark 9 fixed to the mold 6 and automatically determining whether the mold 6 is a conforming product. It is obtained by the configuration of determining automatically.

  Second, it is possible to prevent product quality degradation, deterioration of the molding die 6 and the like due to passing the time when maintenance inspection for the molding die 6 which is a replaceable member is performed. This effect is based on a configuration in which it is automatically determined from the information forming surface 9a of the mark 9 fixed to the mold 6 whether or not it is time to perform maintenance and inspection for the mold 6. can get.

  Thirdly, there is degradation of the information reading means 10 including the convex lens 37 and the reflecting mirror 38 that may be located in a high temperature environment, and degradation of the image sensor 40 that is always located in a place that is not in a high temperature environment. Is prevented. This effect is obtained by the following configuration.

[Example 4]
Based on FIG. 6 and FIG. 7, Example 4 of the manufacturing apparatus and manufacturing method of the articles | goods based on this invention is described. As shown in FIG. 7, the resin sealing device 1 includes one material receiving module A, four molding modules M (see FIG. 1), and one dispensing module B. The resin sealing device 1 includes a power supply 50 that supplies electric power and a control unit 8 (see FIG. 1) that controls each component for the entire resin sealing device 1.

  The material receiving module A and the leftmost molding module M in FIG. 7 can be attached to each other and separated from each other. Adjacent molding modules M can be attached to each other and separated from each other. The rightmost molding module M and dispensing module B in FIG. 7 can be attached to each other and separated from each other. Positioning when mounting the above-described components is performed by known means such as positioning holes and positioning pins. The mounting is performed by well-known means including screwing using a bolt and a nut.

  The material receiving module A includes a substrate material receiving unit 51, a resin material receiving unit 52, and a material transfer mechanism 53. The substrate material receiving unit 51 receives the mounted substrate 54 from the outside of the resin sealing device 1. The resin material receiving unit 52 receives a resin material R made of a powdered solid resin from the outside of the resin sealing device 1.

  With reference to FIG. 6 and FIG. 7, the conveyance system which the resin sealing apparatus 1 has is described. The resin sealing device 1 is provided with an X-direction guide rail 33 along the X direction from the material receiving module A through the four molding modules M to the dispensing module B. The X-direction guide rail 33 is provided so that the main transport mechanism 32 can move along the X direction. The main transport mechanism 32 is provided with a Y-direction guide rail 34 along the Y direction. The Y-direction guide rail 34 is provided with a sub-transport mechanism 35 included in the main transport mechanism 32 so as to be movable along the Y direction. The sub transport mechanism 35 accommodates the mounted substrate 54 in the upper part and accommodates the resin material R in the lower part. The sub transport mechanism 35 reciprocates between a standby position in contact with the X-direction guide rail 33 in one molding module M and the upper portion of the cavity CAV in the lower mold 5. The sub transport mechanism 35 supplies the mounted substrate 54 to the lower surface of the upper mold 4 and supplies the resin material R to the cavity CAV of the lower mold 5.

  In this embodiment, the transport mechanism including the main transport mechanism 32 and the sub transport mechanism 35 is formed by resin-sealing a mounted substrate 54 and a semiconductor chip (not shown) mounted on the mounted substrate 54. Both the sealed substrate 55, which is a molded product, is transported. According to this configuration, since the transport mechanism including the main transport mechanism 32 and the sub transport mechanism 35 serves as both the carry-in mechanism and the carry-out mechanism, the configuration of the resin sealing device 1 is simplified.

  The payout module B includes a molded product transfer mechanism 56 that conveys the sealed substrate 55 and a magazine 57 that houses the sealed substrate 55. In addition, the dispensing module B has a vacuum pump 58. The vacuum pump 58 is a decompression source for decompressing the space including the cavity CAV. The vacuum pump 58 may be used as a reduced pressure source for adsorbing the mounted substrate 54, the sealed substrate 55, and the like for the entire resin sealing device 1. The vacuum pump 58 may be provided in the material receiving module A or in each molding module M.

  According to the present embodiment, adjacent molding modules M among the four molding modules M can be attached to each other and separated from each other. As a result, the number of molding modules M can be increased as demand increases, and the number of molding modules M can be decreased as demand decreases. For example, when the demand for a specific product increases in an area where the factory Fa is located, the resin sealing device 1 of the factory Fb located in an area where the demand is not increasing is used for production of the specific product. The molding module M to be used is separated (the molding module M is removed). The separated molding module M is transported to the factory Fa, and the transported molding module M is added to the resin sealing device 1 of the factory Fa. This makes it possible to meet the increased demand in the area where the factory Fa is located. Therefore, according to the present embodiment, the resin sealing device 1 that can flexibly cope with an increase or decrease in demand is realized.

  The following modification can be adopted as the resin sealing device 1. In the first modified example, the material receiving module A and the dispensing module B are integrated, and one integrated receiving / dispensing module is connected to one end of the resin sealing device 1 (the left end or the right end in FIG. 7). ).

  In the second modified example, the material receiving module A and one molding module M are integrated, and one integrated receiving / molding module is connected to one end of the resin sealing device 1 (in FIG. 7). (Left end or right end) In this case, one molding module M is mounted on the receiving / molding module, or a plurality of molding modules M are sequentially mounted. The resin sealing device 1 is configured by mounting the dispensing module B on the molding module M located at the other end (right end or left end in FIG. 7).

  According to the third modification, in the resin sealing device 1, the main transport mechanism 32 and the sub transport mechanism 35 are combined into a carry-in mechanism, and a carry-out mechanism is provided separately from the carry-in mechanism. In this case, since the carry-in mechanism and the carry-out mechanism operate independently, the efficiency of the molding operation in the resin sealing device 1 is improved.

  The fourth process is a process for attaching a film to the surface of the marker. The process for attaching the film includes screen printing, inkjet printing, painting, and the like. In this case, it is preferable to use a material having characteristics such as high hardness, chemical resistance and heat resistance as the material constituting the film. When these materials are used, the film is hardly removed from the surface of the label. Therefore, information can be stably obtained from the sign 9 of the replaceable member over a long period of time.

  The fifth processing is processing using a so-called 3D printer, such as a layered modeling method represented by an optical modeling method, a cutting modeling method, or the like. By such a three-dimensional modeling method, a fine pattern can be formed on the surface of the sign.

  A label 9 such as a sheet shape or a thin plate shape formed by using the above-described processing is attached to the surface of the mold. The marker 9 may be fixed to the surface of the mold by mechanical means such as screwing. You may form a fine pattern directly on the surface of a replaceable member using the process mentioned above.

  In addition, the replaceable member itself having the mark 9 may be manufactured using the processing described above. The various processes described above may be used to manufacture a component included in the replaceable member and having the label 9 (for example, a cavity block or a gate piece in a resin mold).

  As the fine pattern, an existing code such as a barcode or a matrix type two-dimensional code can be used. You may use the fine pattern which the manufacturer of the manufacturing apparatus, the user, etc. determined suitably. For example, 1 byte (8 bits) of information is represented by 8 consecutive unevennesses by associating the unevenness of the fine pattern with “0” and “1” (or “1” and “0”), respectively. Can do. Information can be expressed by the Morse code by making the irregularities of the fine pattern correspond to the long point and short point (or the short point and long point) of the Morse code, respectively. The Morse code itself may be formed on the replaceable member. In addition, for example, the number of points (dots) constituting one bar in the barcode or the number of points (dots) constituting one component in the two-dimensional code is set to an appropriate number of concave or convex. And the number of the concaves or convexes may be meaningful.

  As the fine pattern, in addition to the irregularities processed by the fine processing, a pattern processed by the fine processing itself, an image itself, or the like may be used. For example, various information can be given meanings corresponding to a plurality of types of patterns and images, and the corresponding information can be read by recognizing those patterns and images.

  The pattern itself, the image itself, and the like processed by microfabrication are used to specify the manufacturer, seller, provider of services related to the replaceable member, etc. (hereinafter referred to as “source for replaceable member”). , Patterns, images, characters, etc. are included. As these patterns, images, characters, etc., which are fine patterns, signs having a function of displaying the origin of the replaceable member, for example, trade names such as company names and trademarks (including registered trademarks) may be used. The fine pattern may include a sign having a function of displaying the origin of the replaceable member.

  In addition, according to the present invention, the following embodiments are possible. According to this embodiment, information for specifying the replaceable member is obtained as the first information from the sign of the replaceable member. History of commodities manufactured based on history information (second information) of exchangeable members obtained from the first information, in other words, history information of exchangeable members obtained based on the first information. (For example, the manufacturing date, the lot number of the article, the manufacturing apparatus used for manufacturing, the replaceable member, etc.) can be tracked. Information (article history information; third information) relating to the history of an article manufactured using the replaceable member is, for example, obtained by the user of the resin sealing device 1 or the molding die 6 as a whole semiconductor manufacturing process. Are stored in a storage unit included in a server for managing the above, a storage unit ME (see FIG. 1) included in the control unit 8 of the resin sealing device 1, and the like. According to this embodiment, for example, a user of a manufacturing apparatus or a replaceable member (history information obtained from a sign included in the replaceable member (exchangeable member history information; second information)) It can be used as information for deriving article history information (third information) indicating the traceability of an article manufactured using a replaceable member.

  The present invention is not limited to the above-described embodiments, and can be arbitrarily changed and selected as needed within a range not departing from the gist of the present invention.
