Description

Technical Field

[0001] The present invention relates to a mounting device for mounting parts on a substrate, for example, via a bonding member (ACF, etc.). Background Technology

[0002] Conventionally, as shown in Patent Document 1, parts (e.g., flexible printed circuit boards, FPCs) are mounted on a substrate via bonding members such as anisotropic conductive film (ACF) or anisotropic conductive paste (ACP) containing conductive particles and thermosetting resin. A mounting device for mounting workpieces containing such anisotropic conductive film (e.g., see Patent Document 2) includes a mounting head movable relative to a workpiece placed on the device, and a heater provided on the mounting head to conduct heat to a mounting tool located at the lower end of the head. Then, by pressing the workpiece against the heating mounting tool, the conductive particles electrically connect the substrate and the part, and the thermosetting resin hardens, fixing them together.

[0003] This type of heater is electrically connected to a heater control unit. By changing the power supplied to the heater through the heater control unit, the temperature of the heater changes. Additionally, a temperature sensor, such as a thermocouple, is assembled inside the heater. The heater control unit adjusts the power supplied to the heater based on the temperature information obtained from the temperature sensor.

[0004] [Existing Technical Documents] [Patent Literature] Patent Document 1: Japanese Patent Application Publication No. 2011-82582 Patent Document 2: Japanese Patent Application Publication No. 2017-118147 Summary of the Invention

[0005] [The problem the invention aims to solve] Furthermore, by monitoring temperature information from a temperature sensor that measures the temperature of the heater, it is possible to indirectly confirm whether the workpiece installation is proceeding smoothly. However, since the workpiece temperature is not directly monitored, it is impossible to detect problems such as poor conductivity caused by phenomena like heat transfer from the installation tool to the joint before the installation tool fully contacts the workpiece, or the thermosetting resin hardening before the conductive particles contained in the joint are fully crushed (pre-hardening). In cases where such problems occur, there is a risk of producing a large number of defective products due to concerns about continuing production. Therefore, relying solely on temperature sensors for production carries a risk.

[0006] In view of this, the object of the present invention is to provide an installation device that can improve the reliability of installation by confirming the condition of the workpiece being heat-pressed during production from a viewpoint different from that of the temperature sensor included in the heater.

[0007] [Technical means to solve the problem] This invention relates to an installation device for heat-pressing a workpiece with a joining member sandwiched between a first member and a second member. The installation device is characterized by comprising: an installation head having a pressure application section and a heater; the pressure application section presses an installation tool directly or indirectly against the second member to press the workpiece; the heater heats the installation tool; a heater control section applies electricity to the heater to cause it to heat up; and a controller capable of controlling the installation head and connected to the heater control section. The controller includes: an application information acquisition section that, when the installation head presses and heats the workpiece, acquires the timing of the pressure application section using the installation tool to press the workpiece and the... The heater control unit provides application information related to the power applied to the heater; the application amount calculation unit calculates the no-load application amount for each predetermined time period based on the application information obtained by the application information acquisition unit when the pressure unit is not pressurizing the workpiece, and calculates the pressing application amount during the pressing time from a first time to a second time obtained by the application information acquisition unit and the pressing application amount during the pressing time calculated by the application information, and subtracts the no-load application amount during the time corresponding to the pressing time from the pressing application amount during the pressing time to calculate the pressing release application amount; and the determination unit determines whether the pressing release application amount is within a predetermined range.

[0008] Furthermore, the present invention provides an installation device for heat-pressing a workpiece having a joining member sandwiched between a first member and a second member. The installation device is characterized by comprising: an installation head having a pressure applying section and a heater; the pressure applying section presses an installation tool directly or indirectly against the second member to apply pressure to the workpiece; the heater heating the installation tool; a heater control section applying electricity to the heater to cause it to heat up; and a controller capable of controlling the installation head and connected to the heater control section, the controller comprising: an application information acquisition section acquiring the pressure applied when the installation head applies pressure and heats the workpiece. The system includes an application information unit that determines the timing of pressurizing the workpiece using the installation tool and the power applied to the heater by the heater control unit; and an application amount calculation unit that calculates the no-load application amount for each predetermined time period based on the application information obtained by the application information acquisition unit when the pressurizing unit is not pressurizing the workpiece, and calculates the pressing application amount during crimping based on the pressurizing time from the first time to the second time obtained by the application information acquisition unit and the pressurizing time calculated by the application information, while the pressurizing unit is pressurizing the workpiece, and subtracts the no-load application amount during the time corresponding to the pressurizing time from the pressing application amount. The application amount under load is used to calculate the release application amount during crimping. When the application information acquisition unit pressurizes and heats a reference workpiece with a known heat capacity (based on the workpiece itself) using the mounting head, it can acquire reference application information related to the timing of the pressurization of the reference workpiece by the pressurization unit and the power applied to the heater by the heater control unit. Based on the timing of the pressurization of the reference workpiece and the reference application information acquired by the application information acquisition unit when the reference workpiece is pressurized and heated using the mounting head, the application amount calculation unit can calculate the reference crimping release amount of the reference workpiece corresponding to the release application amount during crimping. The controller further includes: a temperature information measuring unit for measuring the temperature of the reference workpiece; a heat conduction calculation unit for calculating the reference heat conduction to the reference workpiece based on the heat capacity of the reference workpiece and the temperature of the reference workpiece obtained by the temperature information measuring unit, creating a table or formula that establishes a relationship between the reference heat conduction and the amount of heat release during the reference pressing, and calculating the heat conduction of the workpiece based on the reference heat conduction that establishes a relationship with the reference heat release during the pressing, which is equivalent to the amount of heat release during the pressing; and a discrimination unit for determining whether the heat conduction is within a specified range.

[0009] Furthermore, the present invention provides an installation device for heat-pressing a workpiece having a joining member sandwiched between a first member and a second member.

The pattern creation unit can create a reference application pattern based on the timing of pressurizing the reference workpiece and the reference application information acquired by the application information acquisition unit when the mounting head is used to pressurize and heat the reference workpiece. The controller also includes a discrimination unit that compares the application pattern with the reference application pattern and determines whether the difference between the application pattern and the reference application pattern is within a specified range.

[0018] Hereinafter, one embodiment of the mounting device of the present invention (mounting device 1) will be described with reference to the accompanying drawings. In the following description, the direction shown in FIG1 (the workpiece 100 described later is located below and the mounting head 2 is located above) will be used, but this direction is only an example and is not intended to limit the direction of the mounting device in the present invention.

[0019] First, the aspects relating to the workpiece 100 heat-pressed using the mounting device 1 will be explained. As shown in FIG1, the workpiece 100 of this embodiment is a workpiece in which an ACF 103 is sandwiched between a substrate 101 and an electronic component 102 such as an FPC. Furthermore, the substrate 101 corresponds to the "first component" in this specification, etc. Similarly, the electronic component 102 corresponds to the "second component", and the ACF 103 corresponds to the "bonding component".

[0020] In this embodiment, when heat-pressing the workpiece 100 using the mounting device 1, a cushioning material 110 is also used. As the cushioning material 110, for example, a sheet made of silicone rubber or a strip with a polytetrafluoroethylene (PTFE) film as the base material can be used.

[0021] The buffer material 110 is configured to cover the upper surface of the electronic component 102 during heat pressing of the workpiece 100. Here, when heat pressing the workpiece 100 using the mounting device 1, the electronic component 102 is pressed using the mounting tool 5 (described later). It is assumed that if the mounting tool 5 directly contacts the electronic component 102, it may sometimes damage the electronic component 102. However, by covering the upper surface of the electronic component 102 with the buffer material 110 and pressing it with the mounting tool 5, damage to the electronic component 102 can be prevented. Furthermore, depending on the type, the electronic component 102 may have an uneven shape on its upper surface; for example, considering individual differences in the electronic component 102, the height of this unevenness may vary. Even in this case, by using the buffer material 110, the height variation can be absorbed by the buffer material 110, resulting in uniform pressure on the electronic component 102.

[0022] In this embodiment, the cushioning material 110 is equipped with a cushioning material temperature sensor 111 for measuring the temperature of the cushioning material 110. As an example of the cushioning material temperature sensor 111, a type of cushioning material temperature sensor in which a thermocouple is assembled in a clamp capable of holding the cushioning material 110 can be cited. Furthermore, when assembling the cushioning material temperature sensor 111 onto the cushioning material 110, it is preferable to place it as close as possible to the portion pressed using the mounting tool 5. Additionally, the cushioning material 110 uses a cushioning material with a known heat capacity. The heat capacity HCB (in J / K) of the cushioning material 110 can be calculated by multiplying the specific heat of the raw material used by the volume of the cushioning material 110.

[0023] The dashed line in Figure 1 shows a reference workpiece 200, for example, based on the workpiece 100 used when mass production of the workpiece 100 begins using the mounting device 1. The reference workpiece 200 has the same size as the workpiece 100 and can be heated by the mounting device 1. The reference workpiece 200 is preferably formed from a raw material with high thermal conductivity, excellent heat resistance, and high strength; in this embodiment, it is formed from aluminum nitride. Furthermore, the reference workpiece 200 uses a reference workpiece with a known heat capacity. The specific heat of aluminum nitride is, for example, 720 [J / (kg·K)], therefore, by multiplying the specific heat by the volume of the reference workpiece 200, the heat capacity HCS (in J / K) of the reference workpiece 200 can be calculated.

[0024] In this embodiment, a reference workpiece 200 is provided with a reference workpiece temperature sensor 201, such as a thermocouple, which can measure the temperature of the reference workpiece 200.

[0025] Next, the structure of the mounting device 1 will be described. The mounting device 1 in this embodiment includes the mounting head 2, heater control unit 6, and controller 7 shown in FIG1.

[0026] The mounting head 2 includes a head body 3 as shown in FIG. 1, and a pressure unit (not shown). The head body 3 is configured to move vertically relative to a base (not shown) included in the mounting device 1, and moves up and down when the pressure unit is driven, applying pressure to the workpiece 100 when it descends. The pressure unit may include, for example, a component that rotates the feed screw by a servo motor to move the nut forward and backward, a component of a shaft motor that moves forward and backward relative to a shaft in a non-contact manner using a movable member, or a cylinder that moves the rod forward and backward by introducing a medium such as air.

[0027] Furthermore, the mounting head 2 includes a heater 4 assembled at the lower end of the head body 3. The heater 4 heats the heating element when energized. Methods for heating the heater 4 include, for example, constant-temperature heating or pulse heating. In this embodiment, the heater 4 is a pulse heater that heats using a pulse heating method, and a temperature sensor, such as a thermocouple, is provided in the heater 4.

[0028] Additionally, the mounting head 2 includes a mounting tool 5 assembled at the lower end of the heater 4. The mounting tool 5 is shaped to press the portion of the electronic component 102 that is in contact with the ACF 103. The mounting tool 5 is preferably made of a material with high thermal conductivity. In this embodiment, the mounting tool 5 is made of aluminum nitride.

[0029] The heater control unit 6 has the function of applying power to the heater 4 to cause the heater 4 to heat up. In this embodiment, the heater control unit 6 includes a temperature regulator 6a and a power regulator 6b electrically connected to each other. The temperature regulator 6a is electrically connected to the temperature sensor and controller 7 in the heater 4, and the power regulator 6b is electrically connected to the heating element in the heater 4. Based on an electrical signal related to the target temperature of the heater 4 output from the controller 7 and an electrical signal related to the temperature of the heater 4 obtained from the temperature sensor of the heater 4, the temperature regulator 6a outputs an electrical signal to the power regulator 6b containing information (hereinafter referred to as "power information") relating to the magnitude of the power output by the power regulator 6b to the heater 4. Based on the electrical signal from the temperature regulator 6a, the power regulator 6b outputs power (alternating current) to the heater 4 at a predetermined voltage and current. Here, the power information is, for example, the voltage or current value of the electrical signal output from the temperature regulator 6a to the power regulator 6b; in this case, the power regulator 6b outputs power to the heater 4 corresponding to the magnitude of the voltage value, etc., of the electrical signal. As an example, when the voltage value of the electrical signal changes from 0 V to 10 V, the magnitude of the power output from the power regulator 6b to the heater 4 changes from 0% to 100%. Here, the voltage and current values ​​of the power output from the power regulator 6b to the heater 4 are referred to as "power regulator output information." Furthermore, the power information and the power regulator output information are collectively referred to as "application information." That is, application information is information related to the power applied to the heater 4 by the heater control unit 6, such as the voltage or current value of the electrical signal output from the temperature regulator 6a to the power regulator 6b, and the voltage or current value of the power output from the power regulator 6b to the heater 4. In addition, a similar relationship exists between the power information and the power regulator output information, as exemplified by the relationship between the voltage value of the electrical signal of the temperature regulator 6a and the magnitude of the power from the power regulator 6b.

[0030] The controller 7 is electrically connected to various parts of the mounting device 1, such as the mounting head 2 and the heater control unit 6. The buffer material temperature sensor 111 or the reference workpiece temperature sensor 201 can also be electrically connected to the controller 7 of this embodiment. As shown in FIG2, the controller 7 includes: a control unit 8, which receives electrical signals containing information from various devices connected to the controller 7 and outputs electrical signals containing information to operate these devices to control them; a storage unit 9, connected to the control unit 8, which stores programs or various information that cause the control unit 8 to operate; and an output unit 10, connected to the control unit 8, which allows the operator to perceive information related to the mounting device 1 through vision or hearing. The control unit 8 may, for example, include a programmable logic controller (PLC) or a dedicated board. Additionally, the storage unit 9 may, for example, include a semiconductor memory or a hard disk drive (HDD). Furthermore, the output unit 10 may include, for example, a component that simply emits light, such as a light-emitting diode (LED), a component that specifically displays various information, such as a display, or a component that emits sound, such as a buzzer or a speaker.

[0031] In addition to controlling various devices connected to the controller 7, the control unit 8 of this embodiment is configured to function as the following: application information acquisition unit 11, application amount calculation unit 12, temperature information measurement unit 13, heat conduction calculation unit 14, pattern creation unit 15, discrimination unit 16, and adjustment unit 17.

[0032] The application information acquisition unit 11 has the following functions: when pressurizing and heating the workpiece 100 using the mounting head 2, it acquires application information related to the timing of the pressurizing unit pressurizing the workpiece 100 using the mounting tool 5 and the power applied to the heater 4 by the heater control unit 6.

[0033] In addition, the application information acquisition unit 11 has the following function: when the reference workpiece 200 is pressurized and heated using the mounting head 2, it acquires information related to the timing of the pressurization unit pressurizing the reference workpiece 200 and the power applied to the heater 4 by the heater control unit 6 (hereinafter referred to as "reference application information"). The reference application information corresponds to the application information (power information and power regulator output information when the workpiece 100 is hot-pressed using the mounting device 1), and is a general term for the power information (reference power information) and power regulator output information (reference power regulator output information) when the reference workpiece 200 is hot-pressed using the mounting device 1.

[0034] The application amount calculation unit 12 has the following functions: calculating the no-load application amount Eu0 calculated based on the application information obtained by the application information acquisition unit 11 for each predetermined time when the workpiece 100 is not pressurized by the pressurizing unit; calculating the pressing application amount E1 during the pressing time calculated by the application information acquisition unit 11 based on the pressurizing time from the first time T1 to the second time T2 obtained by the pressurizing unit 11 (refer to Figures 3A to 3C) and the pressing time calculated by the application information; and subtracting the no-load application amount E0 (a value obtained by converting the no-load application amount Eu0 for each predetermined time into a value per unit time from the first time T1 to the second time T2) from the pressing application amount E1 during the pressing time, and calculating the pressing release application amount E2 during the pressing time. Furthermore, the first time T1 and the second time T2 are arbitrary times corresponding to the period (sampling period) of the voltage and current values ​​obtained by the application information acquisition unit 11. In Figures 3A to 3C, the first time T1 coincides with the pressurization start time Ts, when the pressurizing part of the mounting head 2 is driven to lower the head body 3 to begin pressurizing the workpiece 100. However, the first time T1 may also be after the pressurization start time Ts. Furthermore, the second time T2 is before the pressurization end time Tf, when the pressurizing part of the mounting head 2 is driven to raise the head body 3 to end pressurizing the workpiece 100. However, the second time T2 may also coincide with the pressurization end time Tf.

[0035] In addition, the application amount calculation unit 12 has the following function: based on the timing of pressurizing the reference workpiece 200 obtained by the application information acquisition unit 11 when pressurizing and heating the reference workpiece 200 using the mounting head 2, and the reference application information, it calculates the reference pressing release application amount ES of the reference workpiece 200 that is equivalent to the pressing release application amount E2.

[0036] Here, the application information acquisition unit 11 and the application amount calculation unit 12 will be specifically described with reference to Figures 3A to 3D. In the voltage-related graph in Figure 3A, the vertical axis is the AC voltage value (in V) applied to the heater 4 by the power regulator 6b, which is obtained by the application information acquisition unit 11 in the form of application information, and the horizontal axis is time (in seconds). Similarly, in the current-related graph in Figure 3B, the vertical axis is the AC current value (in A) applied to the heater 4 by the power regulator 6b, which is obtained by the application information acquisition unit 11 in the form of application information, and the horizontal axis is time. Furthermore, in the power graph in Figure 3C, the vertical axis is the power value (in W) expressed as the product of the voltage and current values ​​obtained by the application information acquisition unit 11, and the horizontal axis is time. The graphs in Figures 3A to 3C are depicted in black because the period (sampling period) during which the application information acquisition unit 11 obtains the voltage and current values ​​is extremely short. That is, the application information acquisition unit 11 can obtain the voltage, current, and power values ​​in real time. The voltage, current, and power values ​​obtained by the information acquisition unit 11, along with the time of acquisition, are stored in the storage unit 9. Furthermore, Figure 3D is a simplified representation of the graph that was shaded in black in Figure 3C, but is shown in white for ease of explanation.

[0037] When the heater control unit 6 supplies power to the heater 4 as shown in Figures 3C and 3D, the application amount calculation unit 12 confirms the power value before the pressurization start time Ts and the power value after the pressurization end time Tf. Then, it calculates the average of the power value for each predetermined time before the pressurization start time Ts and the power value for each predetermined time after the pressurization end time Tf as the no-load application amount Eu0 for each predetermined time. Furthermore, the no-load application amount Eu0 for each predetermined time can be set using only the power value for each predetermined time before the pressurization start time Ts, or it can be set using only the power value for each predetermined time after the pressurization end time Tf.

[0038] In addition, the application amount calculation unit 12 confirms the pressure application time from the first time T1 to the second time T2, which is obtained by the application information acquisition unit 11 when the workpiece 100 is being pressurized by the pressure application unit, and the power value during the pressure application time. Then, the power value during the pressure application time is calculated as the application amount E1 (in J) during the crimping.

[0039] Furthermore, the application amount calculation unit 12 calculates the no-load application amount E0 (in J) during the time corresponding to the pressurization time based on the calculated pressurization time (second time T2 - first time T1) and the no-load application amount Eu0 for each predetermined time. Then, by subtracting the no-load application amount E0 during the pressurization time from the crimping application amount E1, the crimping release application amount E2 (in J) is calculated (E2 = E1 - E0). In Figure 3D, the crimping release application amount E2 is approximately equivalent to the area of ​​the rectangular portion located between the power value P0 and the power value P1 during the period from the first time T1 to the second time T2.

[0040] The temperature information measurement unit 13 has the following function: to measure the temperature of the reference workpiece 200 based on information from the reference workpiece temperature sensor 201.

[0041] In addition, the temperature information measurement unit 13 has the following function: when the workpiece 100 is heat-pressed using the buffer material 110, the temperature of the buffer material 110 is measured based on the information from the buffer material temperature sensor 111.

[0042] The heat transfer calculation unit 14 has the following functions: it calculates the reference heat transfer QS conducted to the reference workpiece 200 based on the heat capacity HCS of the reference workpiece 200 and the temperature of the reference workpiece 200 obtained by the temperature information measurement unit 13; it creates a table or formula that establishes a relationship between the reference heat transfer QS and the reference pressing release application amount ES; and then, referring to the table or formula, it calculates the heat transfer Q of the workpiece 100 based on the reference heat transfer QS that is related to the reference pressing release application amount ES, which corresponds to the pressing release application amount E2. Here, the table that establishes a relationship between the reference heat transfer QS and the reference pressing release application amount ES is, for example, shown in FIG4, where the values ​​of multiple reference pressing release application amounts ES are related to the values ​​of their respective pressing release application amounts E2. Moreover, the formula that establishes a relationship between the reference heat transfer QS and the reference pressing release application amount ES is, for example, an interpolation formula that interpolates these discrete values ​​when there are multiple values ​​of reference pressing release application amounts ES and pressing release application amounts E2, as shown in FIG4. As an example of this relationship, a first-order approximation curve using the least squares method can be given based on the values ​​of the release application amount ES and the release application amount E2 during crimping, using multiple references.

[0043] In addition, the heat conduction calculation unit 14 has the following function: when the workpiece 100 is heat-pressed using the buffer material 110, the heat conduction heat QB conducted to the buffer material 110 is calculated based on the heat capacity HCB of the buffer material 110 and the temperature of the buffer material 110 obtained by the temperature information measurement unit 13, and the corrected heat conduction heat QR of the workpiece 100 is calculated by subtracting the heat conduction heat QB of the buffer material from the heat conduction heat Q of the workpiece 100.

[0044] The pattern creation unit 15 has the following function: creating an application pattern based on the timing of pressurizing the workpiece 100 from a first time T1 to a second time T2, as obtained by the application information acquisition unit 11. As the application information obtained by the application information acquisition unit 11, for example, when using power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4, the pattern creation unit 15 creates voltage-related graphs, current-related graphs, and power-related graphs from the first time T1 to the second time T2, as shown in Figures 3A to 3C, as image data. Furthermore, the pattern creation unit 15 has the following function: creating a reference application pattern based on the timing of pressurizing the reference workpiece 200 and the reference application information obtained by the application information acquisition unit 11 when pressurizing and heating the reference workpiece 200 using the mounting head 2. That is, the pattern making unit 15 has the following function: when using the reference power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 as the reference application information obtained by the application information acquisition unit 11, it makes the charts shown in Figures 3A to 3C of the reference workpiece 200 as image data. The image data related to the charts of the made workpiece 100 and the image data related to the charts of the reference workpiece 200 are stored in the storage unit 9.

[0045] The discrimination unit 16 has the following functions: performing discrimination related to the amount of heat applied during the pressing E2, discrimination related to the conductive heat Q, discrimination related to the modified conductive heat QR, and discrimination related to the application pattern and the reference application pattern.

[0046] Here, regarding the amount of material applied during crimping, E2, the determination unit 16 has the function of determining whether the amount of material applied during crimping, E2, is within a specified range. The specified range relating to the amount of material applied during crimping, E2, can be determined based on its theoretical value, for example, if it can be derived theoretically, or it can be determined based on the results of test production of the workpiece 100 before mass production using the mounting device 1. In this embodiment, the value that constitutes the specified range is stored in the storage unit 9, and the determination unit 16 determines whether the amount of material applied during crimping, E2, is within the specified range stored in the storage unit 9.

[0047] Furthermore, when the application amount calculation unit 12 calculates the reference pressing release application amount ES of the reference workpiece 200, the determination unit 16 can also calculate the difference between the pressing release application amount E2 and the reference pressing release application amount ES, and determine whether the difference is within a specified range. In this case, the value that falls within the specified range is also stored in the storage unit 9, and the determination unit 16 calculates the difference between the pressing release application amount E2 and the reference pressing release application amount ES, and determines whether the value of the difference is within the specified range stored in the storage unit 9.

[0048] Furthermore, regarding the heat transfer Q, the discrimination unit 16 has the function of determining whether the heat transfer Q is within a specified range. In this embodiment, the value that falls within the specified range is stored in the storage unit 9, and the discrimination unit 16 determines whether the value of the heat transfer Q is within the specified range stored in the storage unit 9. Additionally, regarding the corrected heat transfer QR, the discrimination unit 16 has the function of determining whether the corrected heat transfer QR is within a specified range. In this embodiment, the value that falls within the specified range is stored in the storage unit 9, and the discrimination unit 16 determines whether the value of the corrected heat transfer QR is within the specified range stored in the storage unit 9.

[0049] Furthermore, regarding the applied pattern and the reference applied pattern, the discrimination unit 16 has the function of comparing the applied pattern and the reference applied pattern and determining whether the difference between the applied pattern and the reference applied pattern is within a specified range. To illustrate with a specific example, if the applied pattern is a graph related to electricity as shown in Figures 3C and 3D, it slopes at approximately a certain ratio from time T1 (pressurization start time Ts) to time Ta×2. During this period, the electricity increases by Pa based on time T1, then remains constant for a short time, then decreases, and at the pressurization end time Tf, it becomes the same level of electricity as at the pressurization start time Ts. That is, in the applied pattern, from time T1 to the elapsed time Ta×2, the area increases by (1 / 2) × (Ta×2) × Pa = Ta×Pa. Here, although the reference applied pattern is not illustrated, the slope from time T1 becomes steeper compared to the graphs shown in Figures 3C and 3D. Specifically, the reference application pattern, relative to the charts shown in Figures 3C and 3D, tilts at approximately a constant ratio from time T1 to time Ta. During this period, the electrical power increases by Pa based on time T1, and from time Ta to time (Ta×2), it becomes a constant electrical power Pa, and then remains the same as the application pattern. That is, in the reference application pattern, from time T1 to the elapsed time Ta×2, the area increases by (1 / 2)×Ta×Pa + Ta×Pa = (3 / 2)×Ta×Pa. Furthermore, regarding the difference between the application pattern and the reference application pattern, the discrimination unit 16 is set to converge within a specified range if the difference in area between the two is within (1 / 4)×Ta×Pa. Under this setting, the discrimination unit 16 determines that the difference between the application pattern and the reference application pattern deviates from the specified range.

[0050] The adjustment unit 17 has the following functions: adjusting the timing of the pressure application of the mounting head 2 on the workpiece 100 and / or the power applied to the heater 4 by the heater control unit 6 according to the determination methods in the determination unit 16 (a determination method related to the release application amount E2 during pressing, a determination method related to the conductive heat Q, a determination method related to the correction of the conductive heat QR, and a determination method related to the application pattern and the reference application pattern). Furthermore, the specific adjustment method based on the adjustment unit 17 will be described later.

[0051] Next, as a first method for heat-pressing the workpiece 100 using the mounting device 1, a specific example will be described when the application information acquisition unit 11, application amount calculation unit 12, and discrimination unit 16 included in the control unit 8 are functioning and a discrimination method related to the release application amount E2 during pressing is used. Furthermore, the application information acquired by the application information acquisition unit 11 in the following description refers to the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4.

[0052] First, the workpiece 100 is positioned below the mounting head 2, and pressure and heat are applied to the workpiece 100 via the mounting head 2. Furthermore, in this embodiment, a buffer material 110 is used to pressure and heat the workpiece 100.

[0053] Then, the information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the workpiece 100 using the mounting tool 5, and acquires the application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated).

[0054] Then, the application amount calculation unit 12 calculates the no-load application amount Eu0 of the workpiece 100 for each predetermined time when the workpiece 100 is not pressurized by the pressurizing unit, based on the application information obtained by the application information acquisition unit 11 (as described above, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated), and calculates the application amount Eu0 of the workpiece 100 when the workpiece 100 is pressurized by the pressurizing unit, based on the application information obtained by the application information acquisition unit 11 from the first time T1 to the second time T1. The pressing time up to time T2 and the pressing application amount E1 of the workpiece 100 during the pressing time calculated from the application information are used to calculate the pressing release application amount E2 (in J) from the pressing release application amount E1. This is obtained by subtracting the unloaded application amount E0 of the workpiece 100 during the pressing time (a value obtained by converting the unloaded application amount of the workpiece 100 for each predetermined time into a value per unit time from the first time T1 to the second time T2). The calculated pressing release application amount E2 is stored in the storage unit 9. Furthermore, the first time T1 is the pressing start time Ts when the workpiece 100 is pressurized by the pressing part of the mounting head 2. In addition, the specified range related to the pressing release application amount E2 used in the discrimination unit 16 is pre-derived, for example, based on the results of test production of the workpiece 100 before mass production of the workpiece 100 using the mounting device 1, and the specified range is stored in the storage unit 9.

[0055] Next, the discrimination unit 16 determines whether the obtained pressing release application amount E2 is within the specified range. Here, if the discrimination unit 16 determines that the pressing release application amount E2 is within the specified range, the mounting device 1 operates normally, and the control unit 8 continues the hot pressing operation on the workpiece 100. On the other hand, if the discrimination unit 16 determines that the pressing release application amount E2 deviates from the specified range pre-stored in the storage unit 9, the control unit 8 notifies from the output unit 10 to stop the hot pressing operation on the workpiece 100 as needed. As a result, the main causes of insufficient hardening of ACF 103, etc., can be immediately communicated to the operator, and the production of a large number of defective workpieces 100 can be prevented.

[0056] Furthermore, if the discrimination unit 16 determines that the applied amount E2 during crimping deviates from the predetermined range stored in the storage unit 9, the installation device 1 can be operated without stopping the hot crimping operation on the workpiece 100 by activating the adjustment unit 17.

[0057] The adjustment unit 17 of this embodiment has the following function: when the discrimination unit 16 determines that the amount of pressure release applied during crimping, E2, from the start time of pressure application Ts to the second time T2, deviates from the predetermined range stored in the storage unit 9, the adjustment is made after the second time T2 to adjust the timing of the pressure application unit applying pressure to the workpiece 100 and / or the power applied by the heater control unit 6 to the heater 4, so that the amount of pressure release applied during crimping, E2, from the start of pressure application on the workpiece 100 from the mounting head 2 to the end, converges within a predetermined allowable range.

[0058] According to this adjustment unit 17, even if it is considered that no required heat is applied to the ACF 103 during the period from the start of pressurization Ts to the second time T2, the insufficient heat can be added after the second time T2, so that the production of good workpiece 100 can continue. In addition, according to the mounting device 1 of this embodiment, the condition of the workpiece 100 being heat-pressed during production can be confirmed from a different viewpoint than the temperature sensor included in the heater 4, so the workpiece 100 can be mounted with high reliability.

[0059] Regarding the determination method related to the release application amount E2 during crimping, when the reference crimping release application amount ES of the reference workpiece 200 is calculated by the application amount calculation unit 12, it can be used as shown below. Furthermore, the application information obtained by the application information acquisition unit 11 in the following description is assumed to be the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4.

[0060] First, pressure and heating are applied using the mounting head 2 with the reference workpiece 200. After the reference workpiece 200 is positioned below the mounting head 2, the control unit 8 drives the pressure section of the mounting head 2, causing the head body 3 to descend, and the mounting tool 5 applies pressure to the reference workpiece 200. Additionally, power is supplied from the heater control unit 6 to heat the heater 4, thereby heating the mounting tool 5.

[0061] At this time, the information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the reference workpiece 200 using the mounting tool 5, and acquires the reference application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the reference power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the reference workpiece 200 is heated).

[0062] Based on the timing, voltage, and current values ​​of pressurizing the reference workpiece 200 obtained by the application information acquisition unit 11 as described above, the application amount calculation unit 12 calculates the reference pressurization release application amount ES of the reference workpiece 200 in the same order as the order in which the pressurization release application amount E2 is calculated with reference to Figures 3A to 3D. That is, the application amount calculation unit 12 calculates the reference no-load application amount of the reference workpiece 200 at each predetermined time, calculated based on the reference application information obtained by the application information acquisition unit 11 (as described above, the reference power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the reference workpiece 200 is heated), when the pressurizing unit is pressurizing the reference workpiece 200, and calculates the application amount from the first time T1 to the second time T2 obtained by the application information acquisition unit 11 when the pressurizing unit is pressurizing the reference workpiece 200. The reference pressing time up to time 2 and the reference pressing application amount of the reference workpiece 200 during the pressurization time calculated from the reference application information are used to calculate the reference pressing release application amount ES (in J) from the reference pressing release application amount of the reference workpiece 200 during the time corresponding to the pressurization time (converting the no-load application amount of the reference workpiece 200 for each predetermined time into a value per unit time from the first time T1 to the second time T2). The calculated reference pressing release application amount ES is stored in the storage unit 9. Furthermore, in this embodiment, the first time T1 is the pressurization start time Ts, where pressurization of the reference workpiece 200 begins through the pressurization part of the mounting head 2, and the second time T2 is the pressurization end time Tf, where pressurization ends. In this embodiment, the application amount calculation unit 12 calculates multiple reference pressing release application amounts ES from the pressurization start time Ts to the pressurization end time Tf according to a predetermined time corresponding to the sampling period.

[0063] Thus, after calculating multiple reference pressing times ES from the start time Ts to the end time Tf, the workpiece 100 is placed below the mounting head 2, and pressure and heat are applied to the workpiece 100 through the mounting head 2. Furthermore, in this embodiment, a buffer material 110 is used to pressure and heat the workpiece 100.

[0064] Then, the information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the workpiece 100 using the mounting tool 5, and acquires the application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated).

[0065] Then, the application amount calculation unit 12 calculates the no-load application amount Eu0 of the workpiece 100 for each predetermined time when the workpiece 100 is not pressurized by the pressurizing unit, based on the application information obtained by the application information acquisition unit 11 (as described above, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated), and calculates the application amount Eu0 of the workpiece 100 when the workpiece 100 is pressurized by the pressurizing unit, based on the application information obtained by the application information acquisition unit 11 from the first time T1 to the second time T1. The pressing time up to time T2 and the pressing application amount E1 of the workpiece 100 during the pressing time calculated from the application information are used to calculate the pressing release application amount E2 (in J) from the pressing release application amount E1. This is obtained by subtracting the unloaded application amount E0 of the workpiece 100 during the pressing time (a value obtained by converting the unloaded application amount of the workpiece 100 for each predetermined time into a value per unit time from the first time T1 to the second time T2). The calculated pressing release application amount E2 is stored in the storage unit 9. Furthermore, the first time T1 is the pressing start time Ts when the workpiece 100 is pressurized by the pressing part of the mounting head 2, and the pressing release application amount E2 is obtained multiple times from the pressing start time Ts to the second time T2 at the same time as when the reference pressing release application amount ES is calculated.

[0066] Subsequently, regarding the multiple obtained crimping release application amounts E2 and the reference crimping release application amount ES, the determination unit 16 calculates the difference between the crimping release application amount E2 obtained at the same time and the reference crimping release application amount ES, and determines whether the value of the difference is within a predetermined range pre-stored in the storage unit 9. Furthermore, the determination performed by the determination unit 16 can be based on the difference between each obtained crimping release application amount E2 and the reference crimping release application amount ES, or it can be based on the difference between a consecutive set of crimping release application amounts E2 and the reference crimping release application amount ES.

[0067] Here, if the discrimination unit 16 determines that the difference between the release application amount E2 during crimping and the reference release application amount ES during crimping is within a predetermined range stored in the storage unit 9, the mounting device 1 operates normally, and the control unit 8 continues the hot crimping operation on the workpiece 100. On the other hand, if the discrimination unit 16 determines that the difference between the release application amount E2 during crimping and the reference release application amount ES during crimping deviates from the predetermined range stored in the storage unit 9, the control unit 8 notifies the output unit 10 to stop the hot crimping operation on the workpiece 100 as needed. This allows for immediate communication to the operator of the main causes, such as insufficient hardening of ACF 103, and prevents the production of a large number of defective workpieces 100.

[0068] Furthermore, if the discrimination unit 16 determines that the difference between the release application amount E2 during crimping and the release application amount ES during reference crimping deviates from the predetermined range stored in the storage unit 9, the installation device 1 can be operated without stopping the hot crimping operation on the workpiece 100 by activating the adjustment unit 17.

[0069] The adjustment unit 17 of this embodiment has the following function: when the discrimination unit 16 determines that the difference between the pressing release application amount E2 from the pressurization start time Ts to the second time T2 and the reference pressing release application amount ES from the pressurization start time Ts to the second time T2 deviates from a predetermined range stored in the storage unit 9, the adjustment is made after the second time T2 to the timing of the pressurization unit pressurizing the workpiece 100 and / or the power applied to the heater 4 by the heater control unit 6, so that the difference between the pressing release application amount E2 from the start of pressurization of the workpiece 100 to the end of pressurization from the mounting head 2 and the reference pressing release application amount ES from the start of pressurization of the reference workpiece 200 to the end of pressurization converges within a predetermined allowable range. To illustrate this point with a specific example, the discrimination unit 16 calculates the total of multiple pressure release application amounts E2 obtained during the period from the pressure start time Ts to the second time T2 as the pressure release application amount E2 during the period from the pressure start time Ts to the second time T2, and calculates the total of multiple reference pressure release application amounts ES obtained during the period from the pressure start time Ts to the second time T2 as the reference pressure release application amount ES during the period from the pressure start time Ts to the second time T2, and determines whether the difference between their totals is within a predetermined range stored in the storage unit 9. Then, if the discrimination unit 16 determines that it deviates from the predetermined range, the adjustment unit 17 calculates the total of multiple reference pressure release application amounts ES obtained from the pre-obtained pressure start time Ts to the pressure end time Tf, and calculates the total of multiple pressure release application amounts E2 expected under the current conditions when the workpiece 100 is hot-pressed from the pressure start time Ts to the pressure end time Tf. Then, after the second time T2, the adjustment unit 17 adjusts the timing of pressurizing the workpiece 100 by increasing or decreasing the time when the pressurizing unit pressurizes the workpiece 100, and / or adjusts the power by increasing or decreasing the voltage and current values ​​applied to the heater 4 by the heater control unit 6, so that the difference between them is within the allowable range pre-stored in the storage unit 9.

[0070] According to this adjustment unit 17, even if it is believed that the required heat is not applied to the ACF 103 during the period from the start time of pressurization Ts to the second time T2, the insufficient heat can be added after the second time T2, so that the production of good workpieces 100 can continue.

[0071] Next, as a second method for heat-pressing the workpiece 100 using the mounting device 1, a specific example will be described whereby the application information acquisition unit 11, application amount calculation unit 12, temperature information measurement unit 13, heat conduction calculation unit 14, and discrimination unit 16 included in the control unit 8 are functioning and a discrimination method related to the heat conduction Q is used. In this embodiment, the application information acquired by the application information acquisition unit 11 is also the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4.

[0072] In the second method, firstly, pressure and heating are applied using the mounting head 2 with the reference workpiece 200. After the reference workpiece 200 is positioned below the mounting head 2, the control unit 8 drives the pressure section of the mounting head 2, causing the head body 3 to descend, and the mounting tool 5 applies pressure to the reference workpiece 200. Additionally, power is supplied from the heater control unit 6 to heat the heater 4, thereby heating the mounting tool 5.

[0073] Then, the application information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the reference workpiece 200 using the mounting tool 5, and acquires reference application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, reference power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the reference workpiece 200 is heated). At this time, the temperature information measurement unit 13 measures the temperature of the reference workpiece 200 based on the information from the reference workpiece temperature sensor 201, according to the timing when the application information acquisition unit 11 acquires the reference application information.

[0074] Then, the application amount calculation unit 12 calculates multiple reference pressing release application amounts ES (in J) according to the same order as the first method, from the pressurization start time Ts to the pressurization end time Tf, according to a predetermined time corresponding to the sampling period. The multiple reference pressing release application amounts ES, as well as information related to the temperature of the reference workpiece 200 measured at the time when the reference pressing release application amounts ES are obtained, are stored in the storage unit 9.

[0075] Then, the heat transfer calculation unit 14 calculates the reference heat transfer QS (in J) conducted to the reference workpiece 200 when it is pressurized and heated using the installation tool 5. Specifically, regarding the temperature information of the reference workpiece 200 obtained at the time when the applied amount ES is released during the reference pressing, the temperature difference ΔTS (in K) is calculated based on the temperature of the reference workpiece 200 at the pressurization start time Ts when pressurization of the reference workpiece 200 begins. Then, by multiplying the temperature difference ΔTS by the pre-calculated heat capacity HCS of the reference workpiece 200, the reference heat transfer QS (QS = HCS × ΔTS) at each time the applied amount ES is released during the reference pressing is obtained.

[0076] Furthermore, as shown in Figure 4, the heat transfer calculation unit 14 generates a table 18 that associates the corresponding reference pressing release application amount ES with the reference heat transfer amount QS. Moreover, the reference pressing release application amount ES and the reference heat transfer amount QS are obtained in various ways depending on the timing of the mounting head 2 pressing the reference workpiece 200 and the power applied to the heater 4 by the heater control unit 6. These various reference pressing release application amounts ES and reference heat transfer amounts QS are associated in Table 18. The heat transfer calculation unit 14 of this embodiment also has the function of generating a relational expression that establishes the relationship between the reference heat transfer amount QS and the reference pressing release application amount ES. The relational expression in this embodiment is a first-order approximation curve derived using the least squares method based on the values ​​of the multiple reference pressing release application amounts ES and the values ​​of the pressing release application amount E2 shown in Figure 4. Through this relational expression, the range between the discrete values ​​of the multiple reference pressing release application amounts ES and the values ​​of the pressing release application amount E2 is interpolated.

[0077] Then, the workpiece 100 is positioned below the mounting head 2, and pressure and heat are applied to the workpiece 100 via the mounting head 2. After the workpiece 100 is positioned below the mounting head 2, the control unit 8 drives the pressure section of the mounting head 2, causing the head body 3 to descend, and the mounting tool 5 applies pressure to the workpiece 100. Additionally, power is supplied from the heater control unit 6 to heat the heater 4, thereby heating the mounting tool 5. Furthermore, in this embodiment, a buffer material 110 is also used to apply pressure and heat to the workpiece 100.

[0078] Then, the application information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the workpiece 100 using the mounting tool 5, and acquires application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated). Furthermore, the application amount calculation unit 12 calculates multiple pressing release application amounts E2 (in J) according to the same sequence as the first method, from the pressure start time Ts to the pressure end time Tf, according to a predetermined time corresponding to the sampling period. The calculated multiple pressing release application amounts E2 are stored in the storage unit 9.

[0079] The heat transfer calculation unit 14 refers to Table 18 or the formula and selects a reference pressure release application amount ES that corresponds to the pressure release application amount E2. Since the reference pressure release application amount ES is related to the reference heat transfer QS, by selecting the reference pressure release application amount ES that corresponds to the value of the pressure release application amount E2, the heat transfer Q estimated to be the type of heat transferred to the workpiece 100 can be calculated.

[0080] Subsequently, regarding the calculated type of conductive heat Q, the discrimination unit 16 determines whether it falls within a predetermined range pre-stored in the storage unit 9. Furthermore, regarding the multiple conductive heats Q (conductive heats Q corresponding to a predetermined time period corresponding to the sampling period) contained in the selected type of conductive heat Q, the discrimination performed by the discrimination unit 16 can be based on each conductive heat Q, or it can be based on a continuous set of conductive heats Q that constitutes a predetermined set.

[0081] Here, if the discrimination unit 16 determines that the conductive heat Q is within the specified range stored in the storage unit 9, the mounting device 1 operates normally, and the control unit 8 continues the hot-pressing operation on the workpiece 100. On the other hand, if the discrimination unit 16 determines that the conductive heat Q deviates from the specified range stored in the storage unit 9, the control unit 8 notifies the output unit 10 to stop the hot-pressing operation on the workpiece 100 as needed. This allows the operator to be immediately informed of the main causes of insufficient hardening of ACF 103, and prevents the production of a large number of defective workpieces 100.

[0082] If the discrimination unit 16 determines that the conductive heat Q deviates from the specified range stored in the storage unit 9, the installation device 1 can be operated without stopping the hot pressing operation on the workpiece 100 by activating the adjustment unit 17.

[0083] The adjustment unit 17 of this embodiment has the following function: when the discrimination unit 16 determines that the conductive heat Q deviates from the predetermined range stored in the storage unit 9, it adjusts the timing of pressurizing the workpiece 100 by the pressurizing unit and / or the power applied to the heater 4 by the heater control unit 6 after the second time T2, so that the conductive heat Q from the start of pressurizing the workpiece 100 from the mounting head 2 to the end converges within a predetermined allowable range. Regarding the above function, if a specific example is given, the discrimination unit 16 calculates the total of multiple conductive heats Q contained in the selected type of conductive heat Q during the period from the pressurization start time Ts to the second time T2 as the conductive heat Q from the pressurization start time Ts to the second time T2, and determines whether the total is within the range of the value (the reference value related to the conductive heat from the pressurization start time Ts to the second time T2) pre-stored in the storage unit 9. Then, if the discrimination unit 16 determines that the workpiece 100 deviates from the specified range, the adjustment unit 17 adjusts the timing of pressurizing the workpiece 100 by increasing or decreasing the pressurizing time after the second time T2, and / or adjusts the power by increasing or decreasing the voltage and current values ​​applied to the heater 4 by the heater control unit 6, so as to converge within the allowable range (the reference allowable range of the period from the pressurization start time Ts to the pressurization end time Tf related to heat conduction) pre-stored in the storage unit 9.

[0084] According to this adjustment unit 17, even if it is considered that no required heat is applied to the ACF 103 during the period from the start of pressurization Ts to the second time T2, the insufficient heat can be added after the second time T2, so that the production of good workpiece 100 can continue. In addition, according to the mounting device 1 of this embodiment, the condition of the workpiece 100 being heat-pressed during production can be confirmed from a different viewpoint than the temperature sensor included in the heater 4, so the workpiece 100 can be mounted with high reliability.

[0085] The mounting device 1, by having the function of measuring the temperature of the buffer material 110, can more accurately estimate the heat conducted to the workpiece 100. The following explains the sequence for calculating the corrected conductive heat QR of the workpiece 100 by measuring the temperature of the buffer material 110.

[0086] When the workpiece 100 is pressurized and heated using the installation tool 5, the temperature information measurement unit 13 measures the temperature of the buffer material 110 based on the information from the reference workpiece temperature sensor 201, according to the timing when the application information acquisition unit 11 acquires the reference application information (i.e., the timing when the application amount E2 is released during pressing). The information related to the measured temperature of the buffer material 110 is stored in the storage unit 9.

[0087] Furthermore, regarding the temperature information of the buffer material 110 obtained at the moment of releasing the applied amount E2 during crimping, the heat transfer calculation unit 14 calculates the temperature difference ΔTB (in K) based on the temperature of the buffer material 110 at the pressure start time Ts when the workpiece 100 begins to be pressurized. Then, by multiplying the temperature difference ΔTB by the pre-calculated heat capacity HCB of the buffer material 110, the heat transfer of the buffer material QB (in J) at each moment of releasing the applied amount E2 during crimping is calculated (QB = HCB × ΔTB). Furthermore, the heat transfer calculation unit 14 subtracts the corrected heat transfer QR from the heat transfer Q calculated by referring to Table 18 or the formula to calculate the corrected heat transfer QR at each moment of releasing the applied amount E2 during crimping (QR = Q - QB).

[0088] Then, the discrimination unit 16 determines whether the corrected heat conduction QR is within the predetermined range stored in the storage unit 9. That is, if the discrimination unit 16 determines that the corrected heat conduction QR is within the predetermined range stored in the storage unit 9, the control unit 8 enables the mounting device 1 to operate normally and continues the heat pressing operation on the workpiece 100; if the discrimination unit 16 determines that the corrected heat conduction QR deviates from the predetermined range stored in the storage unit 9, the control unit 8 notifies the output unit 10 to stop the heat pressing operation on the workpiece 100 as needed.

[0089] The heat conduction QB of the buffer material can be considered as the heat conducted to the buffer material 110 when heated by the heater 4. That is, the corrected heat conduction QR, calculated by subtracting the corrected heat conduction QR from the heat conduction Q, can be considered as the net heat conducted to the workpiece 100. Therefore, by using the corrected heat conduction QR in the judgment performed by the discrimination unit 16, the heat conducted to the workpiece 100 can be estimated more accurately, and thus the main causes of insufficient hardening of ACF 103 can be more accurately identified.

[0090] Regarding the adjustment unit 17 included in the mounting device 1 of this embodiment, similarly to the conductive heat Q, even if the determination unit 16 determines that the corrective conductive heat QR deviates from the predetermined range stored in the storage unit 9, the mounting device 1 can be operated without stopping the hot pressing operation on the workpiece 100.

[0091] The adjustment unit 17 of this embodiment has the following function: when the discrimination unit 16 determines that the corrected conduction heat QR deviates from the predetermined range stored in the storage unit 9, it adjusts the timing of pressurizing the workpiece 100 by the pressurizing unit and / or the power applied to the heater 4 by the heater control unit 6 after the second time T2, so that the corrected conduction heat QR from the start of pressurizing the workpiece 100 from the mounting head 2 to the end converges within a predetermined allowable range. To illustrate this with a specific example, the discrimination unit 16 calculates the sum of multiple corrected conduction heat QRs during the period from the pressurization start time Ts to the second time T2 as the corrected conduction heat QR from the pressurization start time Ts to the second time T2, and determines whether the sum is within the range of the value pre-stored in the storage unit 9 (the reference value related to the corrected conduction heat from the pressurization start time Ts to the second time T2). Then, if the discrimination unit 16 determines that the workpiece 100 deviates from the specified range, the adjustment unit 17 adjusts the timing of pressurizing the workpiece 100 by increasing or decreasing the pressurizing time after the second time T2, and / or adjusts the power by increasing or decreasing the voltage and current values ​​applied to the heater 4 by the heater control unit 6, so as to converge within the allowable range (the reference allowable range of the period from the pressurization start time Ts to the pressurization end time Tf related to the correction of heat conduction) stored in the storage unit 9.

[0092] According to this adjustment unit 17, even if it is considered that no required heat is applied to the ACF 103 during the period from the start of pressurization time Ts to the second time T2, the insufficient heat can be added after the second time T2, so that the production of good workpiece 100 can continue. In addition, according to the mounting device 1 of this embodiment, the condition of the workpiece 100 being heat-pressed during production can be confirmed from a different viewpoint than the temperature sensor included in the heater 4, and by using the corrected heat conduction QR, it is possible to determine the condition based on the net heat conducted to the workpiece 100, so the mounting of the workpiece 100 can be performed with higher reliability.

[0093] Next, as a third method for heat-pressing the workpiece 100 using the mounting device 1, a specific example will be described whereby the application information acquisition unit 11, pattern making unit 15, and discrimination unit 16 included in the control unit 8 are functioning and a discrimination method related to the application pattern and the reference application pattern is used. In this embodiment, the application information acquired by the application information acquisition unit 11 is the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4.

[0094] In the third method, firstly, pressure and heating are applied using the mounting head 2 with the reference workpiece 200. After the reference workpiece 200 is positioned below the mounting head 2, the control unit 8 drives the pressure section of the mounting head 2, causing the head body 3 to descend, and the mounting tool 5 applies pressure to the reference workpiece 200. Additionally, power is supplied from the heater control unit 6 to heat the heater 4, thereby heating the mounting tool 5.

[0095] Then, the information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the reference workpiece 200 using the mounting tool 5, and acquires the reference application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the reference power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the reference workpiece 200 is heated).

[0096] Then, the pattern making unit 15 makes a reference application pattern based on the reference pressing time application amount of the reference workpiece 200 during the pressurization period from the first time T1 to the second time T2, calculated by the application information acquisition unit 11 based on the timing of pressurization of the reference workpiece 200 from the first time T1 to the second time T2, while the reference workpiece 200 is being pressurized by the pressurization unit of the mounting head 2. The reference application pattern is, for example, a reference pattern for a good product that applies the required heat to the ACF 103. In this embodiment, the first time T1 is the pressurization start time Ts, where pressurization of the reference workpiece 200 begins by the pressurization unit of the mounting head 2, and the second time T2 is the pressurization end time Tf, where pressurization ends. In addition, when making the reference application pattern, a pattern that includes a portion earlier than the first time T1 or a portion later than the second time T2 may also be made. In this embodiment, the pattern making unit 15 makes voltage-related graphs, current-related graphs, and power-related graphs based on Figures 3A to 3C as image data.

[0097] Thus, after creating the reference application pattern for the reference workpiece 200, the workpiece 100 is placed below the mounting head 2, and pressure and heat are applied to the workpiece 100 by the mounting head 2. After the workpiece 100 is placed below the mounting head 2, the control unit 8 drives the pressure section of the mounting head 2, causing the head body 3 to descend, and the mounting tool 5 applies pressure to the workpiece 100. Additionally, power is supplied from the heater control unit 6 to heat the heater 4, thereby heating the mounting tool 5. Furthermore, in this embodiment, a buffer material 110 is also used to apply pressure and heat to the workpiece 100.

[0098] Then, the information acquisition unit 11 acquires the timing when the pressure unit of the mounting head 2 applies pressure to the workpiece 100 using the mounting tool 5, and acquires the application information related to the power applied to the heater 4 by the heater control unit 6 (in this embodiment, the power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4 when the workpiece 100 is heated).

[0099] Then, the pattern making unit 15 creates an application pattern based on the timing of applying pressure to the workpiece 100 from the first time T1 to the second time T2, as obtained by the application information acquisition unit 11. In this embodiment, the pattern making unit 15 creates voltage-related graphs, current-related graphs, and power-related graphs from the first time T1 to the second time T2, as shown in Figures 3A to 3C, as image data. The created image data is stored in the storage unit 9.

[0100] Next, the discrimination unit 16 compares the applied pattern stored in the storage unit 9 with the reference applied pattern and determines whether the difference between the applied pattern and the reference applied pattern is within a specified range. For example, in the specific example described with reference to Figures 3C and 3D, the area of ​​the reference applied pattern increases by (3 / 2) × Ta × Pa during the period from time T1 to the elapsed time Ta × 2, while the area of ​​the applied pattern increases by Ta × Pa during the same period. Therefore, the difference between the areas of the two is (1 / 2) × Ta × Pa. Here, if the discrimination unit 16 is set such that the difference between the applied pattern and the reference applied pattern converges within a specified range if the difference between the areas of the two is within (1 / 4) × Ta × Pa, the discrimination unit 16 determines that it deviates from the specified range, and the control unit 8 notifies the output unit 10 to stop the hot pressing operation on the workpiece 100 as needed. As a result, the main cause of insufficient hardening of ACF 103 can be immediately communicated to the operator, and the production of a large number of defective workpieces 100 can be prevented.

[0101] Furthermore, by using the adjustment part 17, the mounting device 1 of this embodiment can operate without stopping the hot pressing operation on the workpiece 100.

[0102] The adjustment unit 17 of this embodiment has the following function: when the discrimination unit 16 determines that the difference between the reference application pattern from the pressurization start time Ts to the second time T2 and the application pattern from the pressurization start time Ts to the second time T2 deviates from a predetermined range, the timing of the pressurization unit pressurizing the workpiece 100 and / or the power applied to the heater 4 by the heater control unit 6 after the second time T2 are adjusted so that the difference between the application pattern from the start of pressurization of the workpiece 100 to the end of pressurization from the mounting head 2 and the reference application pattern from the start of pressurization of the reference workpiece 200 to the end of pressurization converges within a predetermined allowable range. To illustrate this point, if we take a specific example, the applied pattern is the power-related graph described with reference to Figures 3C and 3D. The base applied pattern is a graph that slopes steeply from time T1 relative to the graphs shown in Figures 3C and 3D (that is, a graph that slopes at approximately a certain ratio from time T1 to time Ta, during which the power increases by Pa based on time T1, becomes a certain power Pa from time Ta to time (Ta×2), and then is the same graph as the applied pattern). Furthermore, if the difference between the area of ​​the reference applied pattern and the applied pattern is within (1 / 4) × Ta × Pa, the discrimination unit 16 sets the area difference between the applied pattern and the reference applied pattern to converge within a specified range. The adjustment unit 17 adjusts the timing of pressurizing the workpiece 100 by increasing or decreasing the pressurizing time of the pressurizing unit, and / or adjusts the power by increasing or decreasing the voltage and current values ​​applied to the heater 4 by the heater control unit 6, so that the area of ​​the applied pattern chart from the pressurization start time Ts to the pressurization end time Tf is approximately the same as the area of ​​the reference applied pattern chart from the pressurization start time Ts to the pressurization end time Tf.

[0103] According to this adjustment unit 17, even if it is considered that no required heat is applied to the ACF 103 during the period from the start of pressurization Ts to the second time T2, the insufficient heat can be added after the second time T2, so that the production of good workpiece 100 can continue. In addition, according to the mounting device 1 of this embodiment, the condition of the workpiece 100 being heat-pressed during production can be confirmed from a different viewpoint than the temperature sensor included in the heater 4, so the workpiece 100 can be mounted with high reliability.

[0104] The present invention has been described above as one embodiment, but the invention is not limited to this specific embodiment. Various modifications and alterations can be made within the scope of the spirit of the invention as set forth in the claims, unless otherwise specified in the description. For example, the structure of the embodiment can be appropriately added to or deleted from. Furthermore, the structure of another embodiment can also be provided. In addition, the effects in the embodiments described are merely illustrative of the effects produced by the present invention and do not imply that the effects based on the present invention are limited to those effects.

[0105] For example, in the described embodiment, the application information acquired by the application information acquisition unit 11 uses power regulator output information related to the voltage and current values ​​output from the power regulator 6b to the heater 4. The application information may also be power information contained in the electrical signal output by the temperature regulator 6a to the power regulator 6b. That is, the information acquired by the application information acquisition unit 11 may, for example, be the voltage or current value of the electrical signal output from the temperature regulator 6a to the power regulator 6b.
