Description

  The present invention relates to a resin curing device that cures a photocurable resin by irradiating the photocurable resin with light.

  2. Description of the Related Art Conventionally, in order to decorate nails such as hands and feet, it has been generally performed to attach an artificial nail such as a nail tip or a sculpture to the nail. As this artificial nail, there is a gel nail that forms an artificial nail using a gel mainly composed of urethane acrylic resin or the like. Gel is a kind of photo-curing resin, and is cured into an artificial nail when irradiated with light in a specific ultraviolet region.

  For this reason, the gel nail requires a resin curing device that irradiates light in the ultraviolet region in order to cure the gel. Here, the flash discharge tube filled with xenon gas generates light in a wide range of wavelengths (infrared region, visible light, and ultraviolet region), and can cure various cured resins having different curing wavelengths. It may be used for the light source of a kind of resin curing device (see, for example, Patent Document 1). Accordingly, the resin curing device includes a capacitor for supplying electric power to the flash discharge tube.

JP 2011-76825 A Japanese Utility Model Publication No. 62-2032

  Since the flash discharge tube is a light source that emits light only once, the amount of light required to cure the resin cannot be obtained with only one light emission, so this type of resin curing device is required for a single curing operation. In order to obtain a sufficient amount of light, the flash discharge tube is made to emit light many times continuously. That is, the amount of light necessary to cure the resin is obtained by continuously repeating the charging of the capacitor and the light emission of the flash discharge tube. In order for the flash discharge tube to emit light continuously, it is necessary to charge and discharge the capacitor at high speed. Therefore, a household (commercial) AC power source (hereinafter also simply referred to as an AC power source) is adopted as the power source of the flash discharge tube. (See, for example, Patent Document 2). This type of flash discharge device includes a half-wave voltage doubler rectifier circuit for boosting the voltage of the AC power source and charging the capacitor with the power supplied to the flash discharge tube. By using this type of flashlight discharge device in a resin curing device, even when the flashlight discharge tube continuously emits a large number of times to cure the resin, the flashlight discharge tube can emit light without running out of power. be able to.

  By the way, the charging voltage charged to the capacitor from the AC power source via the half-wave voltage doubler rectifier circuit is 100V, which is the standard voltage (hereinafter simply referred to as standard voltage) of household AC power source in Japan. As shown in FIG. 4, it increases with the passage of time from the start of charging. The effective value of the voltage of the AC power supply may fluctuate depending on the actual usage environment of the device due to factors such as power demand, the influence of the electrical equipment in the building, and simultaneous use with other electrical devices. For example, when the effective value of the AC power supply voltage is reduced to 90 V in the actual usage environment of the device, the charging voltage charged in the capacitor from the 90 V AC power supply via the booster circuit is shown in FIG. Thus, it becomes lower than that at 100V. In addition, the amount of voltage increase in one cycle of alternating current becomes smaller (the charging speed becomes slower). This is because the voltage value that can be boosted by the half-wave voltage doubler rectifier circuit depends on the voltage value of the AC power supply.

  On the other hand, the flash discharge tube generally has the property that the time from the start of power supply from the capacitor to the actual start of light emission becomes faster as the charge voltage of the capacitor is higher, and the light emission starts later as it is lower.

  Therefore, if the capacitor is charged via the half-wave voltage doubler rectifier circuit when the AC power supply voltage is lower than the standard voltage, the flash discharge tube actually emits light from the start of power supply from the capacitor to the flash discharge tube. The time until the time becomes slower than the time until the start of light emission of the flash discharge tube powered by the capacitor charged by boosting the standard voltage. When the power supply to the flashlight discharge tube is stopped at a constant timing regardless of the effective value of the voltage of the AC power supply, when the power is supplied to the flashlight discharge tube by the charged capacitor by boosting the standard voltage In comparison, the light emission time of the flash discharge tube is shortened and the amount of light emission is reduced.

  Therefore, if the flash discharge tube emits light continuously many times at a low AC power supply voltage, light emission with a small amount of light will accumulate, and power is supplied to the flash discharge tube from a capacitor charged by boosting the standard voltage. Even when the light was emitted the same number of times as in the case where the resin was emitted, a total light emission amount sufficient to cure the resin could not be obtained.

  Conversely, when power is supplied to the flash discharge tube in a state higher than the standard voltage, the time from when the power supply is started until the flash discharge tube actually emits light is charged by boosting the standard voltage. The time until the start of light emission of the flash discharge tube supplied with power from the capacitor is shortened. Therefore, when light emission is stopped at a fixed timing regardless of the effective value of the voltage of the AC power supply, the flash discharge tube is more powerful than the case where power is supplied to the flash discharge tube by boosting the standard voltage and charging the capacitor. There will be too much light emitted.

  In this way, when the effective value of the actual AC power supply voltage fluctuates with respect to the standard voltage, the standard voltage is boosted and power is supplied from the charged capacitor to cause the flash discharge tube to emit light. As a result, the total light emission amount of the flash discharge tube may vary, and the finish of the resin curing may not be constant.

  Therefore, an object of the present invention is to provide a resin curing device that suppresses variations in the total light emission amount of the flash discharge tube even if the effective value of the voltage of the AC power supply varies.

  A resin curing device according to the present invention includes a flash discharge tube, a charging unit that is charged by an AC power source for each light emission of the flash discharge tube, and a light emission control that controls power supply from the charging unit toward the flash discharge tube. The light emission control unit specifies an effective value of the voltage of the AC power source based on the charging voltage of the charging unit, and sums the light emission amount of the flash discharge tube according to the effective value of the voltage of the specified AC power source. Is characterized in that the light emission condition is determined so that the amount of light necessary to cure the resin is reached, and the power supply to the flash discharge tube is controlled.

  According to such a configuration, the charging unit is charged by the AC power supply. The flash discharge tube emits light by the electric power charged in the charging unit. After the flash discharge tube emits light only once, the charging unit is charged by the AC power supply. In the resin curing device, charging of the charging unit and light emission of the flash discharge tube are repeated to obtain continuous light emission of the flash discharge tube. Thereby, the amount of light emission is accumulated, and the amount of light necessary for the resin to cure can be obtained.

  Here, when the light emission control unit supplies power to the flash discharge tube, the light emission control unit specifies the effective value of the voltage of the AC power supply from the charging voltage charged in the charging unit. Then, the light emission control unit determines the light emission condition corresponding to the effective value, which is the light emission condition of the flash discharge tube, and the total light emission amount necessary for curing the resin. As a result, the light emission control unit controls power supply to the flash discharge tube under the determined light emission conditions. Thereby, even when the voltage of the AC power supply is low, the total light emission amount at the time when the continuous light emission of the flash discharge tube is completed is not reduced. Even when the voltage of the AC power supply is high, the total light emission amount is not too large.

  Moreover, as another aspect of the resin curing device according to the present invention, the light emission control unit is configured to charge the charging voltage of the charging unit at an interval of a half cycle or more of the AC cycle of the AC power supply when charging the flash discharge tube before the first light emission. By measuring multiple times, the amount of voltage increase during each measurement may be acquired, and the effective value of the voltage of the AC power supply may be specified in a state where the amount of voltage increase is below a predetermined threshold.

  According to such a configuration, the amount of voltage increase per cycle of alternating current decreases as the charging is approached. Therefore, when charging the flash discharge tube before the first light emission, it may be determined that the charging is completed (hereinafter simply referred to as a threshold). Because the effective value of the voltage of the AC power supply is specified when the voltage rises to the following level, the light emission control unit correctly determines the effective value of the AC power supply voltage after determining the completion of charging of the charging unit. Can be identified. In addition, it is possible to complete charging according to the charging time at the current AC power supply voltage without providing a long charging standby time according to the initial charging time when the standard voltage changes to the lowest voltage that can be assumed. Judgment can be made. Thereby, the time until the light emission control unit supplies power to the flash discharge tube can be shortened.

  Further, as another aspect of the resin curing device according to the present invention, the light emission control unit is configured such that when the effective value of the voltage of the specified AC power supply is higher than a reference value corresponding to the standard voltage, the flash discharge tube per time When the flash time is shorter than the reference time corresponding to the standard voltage and the effective value of the specified AC power supply voltage is lower than the reference value corresponding to the standard voltage, the flash time per flash discharge tube is standard It may be longer than the reference time corresponding to the voltage.

  According to such a configuration, when the effective value of the voltage of the AC power supply is higher than the reference value corresponding to the standard voltage, the maximum voltage of the power charged in the charging unit is higher than the reference value corresponding to the standard voltage. Therefore, the actual light emission start time of the flash discharge tube is earlier than when the effective value of the voltage of the AC power supply is lower than the reference value corresponding to the standard voltage. Therefore, when the effective value of the voltage of the AC power supply is higher than the reference value corresponding to the standard voltage, the light emission control unit shortens the light emission time per flash discharge tube to be shorter than the reference time corresponding to the standard voltage. . Conversely, when the effective value of the voltage of the AC power supply is lower than the reference value corresponding to the standard voltage, the light emission time per flash discharge tube is set longer than the reference time corresponding to the standard voltage. As a result, even if there is a difference in the effective value of the voltage of the AC power supply, the single light emission amount of the flash discharge tube can be made constant, and consequently the total light emission amount due to the continuous light emission of the flash discharge tube can be made constant. be able to.

  Further, as another aspect of the resin curing device according to the present invention, the light emission control unit determines the total number of times the flash discharge tube emits light when the effective value of the specified AC power supply voltage is higher than a reference value corresponding to the standard voltage. When the effective value of the specified AC power supply voltage is lower than the reference number corresponding to the standard voltage, the total number of flash discharges is less than the reference number corresponding to the standard voltage. May be increased.

  According to such a configuration, when the effective value of the voltage of the specified AC power supply is higher than the reference value corresponding to the standard voltage, the number of flash discharges is reduced from the reference number corresponding to the standard voltage. The total light emission amount by continuous light emission of the discharge tube can be made constant. On the contrary, when the effective value of the voltage of the specified AC power supply is lower than the reference value corresponding to the standard voltage, the flash discharge tube emits more times than the reference number corresponding to the standard voltage. The total light emission amount by continuous light emission can be made constant.

  Further, as another aspect of the resin curing device according to the present invention, the charging unit includes a capacitor for charging power supplied to the flash discharge tube, and a protection resistor connected to the capacitor, and a plurality of protection units having different resistance values. You may have a resistance and the resistance connection part which selectively connects the protection resistance according to the effective value of the voltage of the alternating current power supply specified with the light emission control part with respect to a capacitor | condenser.

  According to such a configuration, the resistance connection portion selectively connects the protective resistance having a resistance value corresponding to the specified voltage value of the AC power supply to the capacitor, so that the charging voltage of the capacitor approximates. As a result, even if the effective value of the voltage of the AC power supply is lower than the reference value corresponding to the standard voltage, the total light emission amount at the completion of continuous light emission of the flash discharge tube is not reduced, and the voltage of the AC power supply is reduced. Even when the effective value of is higher than the reference value corresponding to the standard voltage, the total light emission amount is not too large.

  Further, as another aspect of the resin curing device according to the present invention, the light emission control unit includes a voltage specifying unit that specifies an effective value of the voltage of the AC power supply from a charging voltage of the charging unit, and a plurality of light emission conditions for the flash discharge tube. The light emission condition determining unit for determining the light emission condition of the flash discharge tube using the effective value of the voltage of the AC power source specified by the voltage specifying unit from the table, and the flash discharge according to the light emission condition determined by the light emission condition determining unit You may have the light emission instruction | indication part which light-emits a pipe | tube.

  According to such a configuration, the voltage specifying unit specifies the effective value of the voltage of the AC power supply using the charging voltage of the charging unit. And a voltage specific | specification part sends the effective value of the voltage of the specified alternating current power supply to the light emission condition determination part. The light emission condition determination unit determines the light emission condition from a table in which a plurality of light emission conditions for the flash discharge tube are set, using the effective value of the voltage of the specified AC power supply. The light emission condition determination unit sets the determined light emission condition in the light emission instruction unit. The light emission instructing unit causes the flash discharge tube to emit light in accordance with the light emission conditions set by the light emission condition determining unit. Thereby, even if there is a difference in the effective value of the voltage of the AC power supply, the light emission control unit can cause the flash discharge tube to emit a light amount appropriate for curing the photocurable resin.

  Further, as another aspect of the resin curing device according to the present invention, the light emission control unit includes a voltage specifying unit that specifies an effective value of the voltage of the AC power source from a charging voltage of the charging unit, and an AC power source specified by the voltage specifying unit. By using the effective value of the voltage, a light emission condition related to the protective resistance to be connected is determined from a table in which a plurality of light emission conditions for identifying the protective resistance selectively connected to the capacitor is set, and the protection to be connected A light emission condition determining unit that sets a light emission condition related to the resistance in the resistance connection unit, and the resistor connection unit may connect the protective resistor to the capacitor based on the set light emission condition.

  According to such a configuration, the voltage specifying unit specifies the effective value of the voltage of the AC power supply using the charging voltage of the charging unit. And a voltage specific | specification part sends the effective value of the voltage of the specified alternating current power supply to the light emission condition determination part. The light emission condition determining unit emits the protective resistance to be connected from a table in which a plurality of light emission conditions for identifying the protective resistance to be selectively connected to the capacitor is set by using the effective value of the voltage of the specified AC power supply. Determine as a condition. The light emission condition determination unit sets the light emission condition related to the protective resistance to be connected to the resistance connection unit. The resistance connection unit connects the protective resistance selected based on the set light emission condition to the capacitor. Thereby, even if there is a difference in the voltage value of the AC power supply, the light emission control unit can make the total light emission amount of the flash discharge tube constant.

  According to the present invention, even if the voltage of the AC power supply fluctuates, there is an excellent effect that variation in the total light emission amount of the flash discharge tube can be suppressed.

  A first embodiment of a resin curing device according to the present invention will be described with reference to FIGS. 1 to 4.

  As shown in FIG. 1, a resin curing device 1 according to this embodiment includes a flash discharge tube 2, a charging unit 4 that is charged by an AC power source 3 for each light emission of the flash discharge tube 2, and the charging unit 4. A light emission control unit 5 that controls power supply from the flash unit to the flash discharge tube 2, a pair of voltage dividing resistors 6 and 7 provided between the charging unit 4 and the flash discharge tube 2, and a trigger voltage applied to the flash discharge tube 2. , And a switching element 9 for controlling the light emission of the flash discharge tube 2. Here, the light emission control unit 5 specifies the effective value of the voltage of the AC power source 3 based on the charging voltage of the charging unit 4, and the light emission amount of the flash discharge tube 2 according to the specified effective value of the voltage of the AC power source 3. The light emission conditions are determined so that the total amount of light (total light emission amount) becomes a light amount necessary for curing the resin, and the power supply to the flash discharge tube 2 is controlled. In the present embodiment, the light emission control unit 5 turns on and turns off the power supplied from the charging unit 4 to the flash discharge tube 2 according to the effective value of the voltage of the AC power supply 3 as the light emission condition. And the power supply from the charging unit 4 toward the flash discharge tube 2 is controlled. That is, the light emission control unit 5 determines the timing for starting and stopping the light emission of the flash discharge tube 2 and controls the power supply from the charging unit 4 toward the flash discharge tube 2.

  When the switching element 9 is turned on, the flash discharge tube 2 emits light by the application of the trigger voltage by the trigger unit 8 and the electric power charged in the charging unit 4, and the light is applied to the photocurable resin applied to the nail. (For example, ultraviolet light) is irradiated. The flash discharge tube 2 stops emitting light when the switching element 9 is turned off. Thus, the flash discharge tube 2 emits light once by the on / off operation of the switching element 9. In the present embodiment, the flash discharge tube 2 emits light continuously a predetermined number of times by repeating the on / off operation of the switching element 9.

  The charging unit 4 includes a first capacitor 10 connected to the AC power supply 3 via a protective resistor (not shown), a first diode 12 connected to the first capacitor 10, and the first capacitor 10 and the first diode 12. One end is connected between the second diode 11 and the other end is connected to the AC power supply 3. One end is connected to the second diode 11, and the other end is connected between the AC power supply 3 and the second diode 11. A second capacitor 13. That is, in this embodiment, the charging unit 4 constitutes a half-wave voltage doubler rectifier circuit. With such a circuit configuration, the charging unit 4 is configured to be able to store power in the second capacitor 13 that is approximately 2√2 times the effective value of the voltage of the AC power supply 3.

  The pair of voltage dividing resistors 6 and 7 are provided to measure the voltage of the second capacitor 13. Specifically, one end of the pair of voltage dividing resistors 6 and 7 is connected between the first diode and the second capacitor 13, and the other end is connected between the AC power supply 3 and the second capacitor 13. Further, the A / D converter 14 is connected between the voltage dividing resistors 6 and 7, and a voltage value obtained by dividing the charging voltage of the second capacitor 13 is transmitted to the A / D converter 14.

  As shown in FIG. 1 or 2, the light emission control unit 5 includes an A / D conversion unit 14 connected between the voltage dividing resistors 6 and 7, and the voltage dividing resistors 6 and 7 at the A / D conversion unit 14. As a monitor voltage value obtained by digitally converting the voltage value of the charging unit 4 (second capacitor 13) divided by the number of times, the flash discharge tube 2 is acquired a plurality of times before the first light emission, and the obtained voltage change amount at each time is obtained. Using the voltage comparison unit 15 for comparing with the threshold value, the voltage specifying unit 16 for specifying the effective value of the voltage of the AC power supply 3 from the monitor voltage value, and the effective value of the voltage of the AC power supply specified by the voltage specifying unit 16, A light emission condition determining unit 17 for determining the light emission conditions of the flash discharge tube 2 from a table in which a plurality of light emission conditions of the flash discharge tube 2 are set, and the flash discharge tube 2 according to the light emission conditions determined by the light emission condition determining unit 17. And a light emission instruction unit 18 for emitting light. That. In the present embodiment, the light emission control unit 5 sets the charging voltage of the charging unit a plurality of times while charging the flash discharge tube 2 before the first light emission, with the interval between each measurement being at least half the AC cycle of the AC power supply. By measuring, the amount of voltage increase during each measurement is acquired, and the effective value of the voltage of the AC power supply is specified in a state where the amount of voltage increase is below a predetermined threshold. Further, in the present embodiment, the light emission control unit 5 standardizes the light emission time per flash discharge tube 2 when the effective value of the voltage of the specified AC power supply 3 is higher than the reference value corresponding to the standard voltage. When the effective value of the voltage of the specified AC power supply 3 is shorter than the reference time corresponding to the voltage and lower than the reference value corresponding to the standard voltage, the light emission time per flash discharge tube 2 is set to the standard voltage. Make it longer than the corresponding reference time. The light emission control unit 5 measures the charging voltage of the charging unit 4 a plurality of times with an interval equal to or longer than the half cycle of the AC power supply. The half-wave voltage doubler rectifier circuit is measured every half cycle of the AC cycle. This is because the two capacitors 13 are charged, and the charging voltage is not continuously measured while the charging voltage does not change.

  The A / D conversion unit 14 is connected between the pair of voltage dividing resistors 6 and 7, and transmits the monitor voltage value obtained by digitally converting the divided voltage value of the second capacitor 13 to the voltage comparison unit 15.

  The voltage comparison unit 15 is a monitor voltage digitally converted by the A / D conversion unit 14 every predetermined time (interval of the AC cycle of the AC power source) at the time of charging the flash discharge tube 2 before the first light emission. Get the value. Then, the voltage comparison unit 15 calculates the difference between the monitor voltage value acquired from the A / D conversion unit 14 and the monitor voltage value acquired immediately before. The voltage comparison unit 15 determines that the charging of the second capacitor 13 has been completed when the difference between the monitor voltage values is within a predetermined threshold. This threshold value is a value corresponding to a voltage increase amount that is small enough to be considered to have reached the completion of charging, based on the fact that the voltage increase amount in one cycle of AC decreases as the second capacitor 13 approaches the completion of charging. is there. When the voltage comparison unit 15 determines that the charging of the second capacitor 13 has been completed, the voltage comparison unit 15 sends the last acquired monitor voltage value to the voltage specifying unit 16.

  The voltage specifying unit 16 specifies the effective value of the voltage of the AC power supply 3 based on the monitor voltage value sent from the voltage comparing unit 15. Specifically, the voltage specifying unit 16 sets the respective resistance values of the voltage dividing resistors 6 and 7 as R1 and R2, and sets the monitor voltage value sent from the voltage comparison unit 15 as Vm. Vc is calculated by the following formula.

Vc = Vm × (R1 + R2) / R2
And the effective value Vf of the voltage of AC power supply 3 is specified with the following formula | equation from the calculated charging voltage Vc of the 2nd capacitor | condenser 13. FIG.

Vf = Vc / 2√2
The voltage specifying unit 16 sends the effective value Vf of the specified voltage of the AC power supply 3 to the light emission condition determining unit 17.

  The light emission condition determination unit 17 determines a light emission condition to be set in the light emission instruction unit 18 from a table in which a plurality of light emission conditions of the flash discharge tube 2 are set, based on the specified effective value of the voltage of the AC power supply 3. The light emission condition determination unit 17 sets the determined light emission condition in the light emission instruction unit 18. In the present embodiment, the light emission condition determination unit 17 determines the light emission conditions from a table in which different light emission conditions are set according to the effective value of the voltage of the AC power supply 3. Specifically, the light emission condition determination unit 17 emits the flash discharge tube 2 for each effective value of the voltage of the AC power supply 3 (between the time when the switching element 9 is turned on and the time when the switching element 9 is turned off). The light emission condition is determined from the table set with the time) as the light emission condition. For example, when the effective value of the voltage of the AC power supply 3 is a reference value (for example, 95V to AC105V near the standard voltage), the light emission condition determination unit 17 sets the time for emitting the flash discharge tube 2 as the reference time. When the light emission condition and the effective value of the voltage of the AC power supply 3 are higher than the reference value, the light emission condition that makes the flash discharge tube 2 emit light shorter than the reference time and the effective value of the voltage of the AC power supply 3 are the reference. When the value is lower than the value, the light emission condition is determined based on a table in which the light emission condition for making the time for emitting light from the flash discharge tube 2 longer than the reference time is set.

  The light emission instructing unit 18 controls on / off of the switching element 9 based on the light emission condition determined by the light emission condition determining unit 17. Specifically, the light emission instructing unit 18 controls on / off of the switching element 9 for the time indicated by the light emission condition. Thereby, the light emission instruction | indication part 18 makes the flash discharge tube 2 light-emit for the time shown by the light emission conditions.

  The trigger unit 8 is provided to apply a trigger voltage to the flash discharge tube 2 when the flash discharge tube 2 emits light, and applies a trigger voltage to the flash discharge tube 2 for each light emission when the flash discharge tube 2 emits light each time. Specifically, when the switching element 9 is turned on, the trigger unit 8 boosts the power of the second capacitor 13 and applies the trigger voltage to the flash discharge tube 2. Thereby, the trigger part 8 reduces the impedance between the both electrodes of the flash discharge tube 2 by ionizing the gas (for example, xenon gas) enclosed in the flash discharge tube 2, and discharges between both electrodes. The flash discharge tube 2 is caused to emit light. The trigger unit 8 stops applying the trigger voltage to the flash discharge tube 2 when the switching element 9 is turned off.

  The switching element 9 is an IGBT (insulated gate bipolar transistor), and has a gate connected to the light emission control unit 5 and is turned on by a light emission signal (ON signal) output from the light emission control unit 5. And the switching element 9 will be in an OFF state by the light emission signal (ON signal) output from the light emission control part 5 being cut off. The switching element 9 causes the flash discharge tube 2 to emit light when turned on, and stops the light emission of the flash discharge tube 2 when turned off.

  Next, the operation of the resin curing device 1 according to this embodiment will be described using the flowchart of FIG.

  As shown in FIG. 3, after the resin curing device 1 is connected to the AC power source 3, the light emitting button (not shown) is turned on, so that the charging unit 4 (second capacitor 13) is connected to the AC power source 3. Charging is started (step S1). Charging unit 4 (second capacitor 13) is charged with power boosted from the voltage of AC power supply 3 by a half-wave voltage doubler rectifier circuit. The voltage dividing resistors 6 and 7 are energized by the electric power charged in the charging unit 4 and divide the voltage according to the charging voltage of the charging unit 4 (second capacitor 13).

  The light emission control unit 5 waits until a predetermined time (first predetermined time, for example, 500 msec) elapses (step S2). And the light emission control part 5 measures the voltage of the voltage dividing resistor 7 after progress of predetermined time. Specifically, the A / D conversion unit 14 sends a monitor voltage obtained by digitally converting the voltage of the voltage dividing resistor 7 to the voltage comparison unit 15. The voltage comparison unit 15 acquires the monitor voltage value converted by the A / D conversion unit 14. (Step S3).

  The light emission controller 5 further measures the voltage of the voltage dividing resistor 7 after a predetermined time (second predetermined time, for example, 50 msec) has elapsed (step S4) (step S5). Specifically, the A / D conversion unit 14 sends a monitor voltage obtained by digitally converting the voltage of the voltage dividing resistor 7 to the voltage comparison unit 15. The voltage comparison unit 15 acquires the monitor voltage value converted by the A / D conversion unit 14 and compares it with the voltage value acquired immediately before (the monitor voltage value acquired before the second predetermined time). As shown in FIGS. 9A and 9B, the amount of increase in the charging voltage of the charging unit 4 becomes smaller as the maximum voltage that can be charged using the AC power source 3 is approached. As a result of the comparison, when the amount of increase in the monitor voltage value is equal to or less than the threshold value, the acquired voltage value is sent to the voltage specifying unit 16 assuming that the charging of the charging unit 4 is completed (YES in step S6).

  On the other hand, the voltage comparison unit 15 determines that the charging of the charging unit 4 is not completed when the amount of increase in the monitor voltage exceeds the threshold as a result of the comparison, and further determines a predetermined time (second predetermined time, For example, after 50 msec), the voltage of the voltage dividing resistor 7 is acquired again, and the comparison of the voltage value is repeated until the increase amount of the monitor voltage value becomes equal to or less than the threshold value (NO in step S6).

  The voltage specifying unit 16 specifies the effective value of the voltage of the AC power supply 3 based on the voltage value sent from the voltage comparing unit 15 (step S7).

For example, in the present embodiment, the light emission condition determination unit 17 refers to a table in which a plurality of light emission conditions of the flash discharge tube 2 are set based on the effective value of the voltage of the specified AC power supply 3. 3 light emission conditions of an effective value 105V or more of the voltage of 3; a light emission condition of the effective value 105V to 95V of the voltage of the AC power supply 3; and a light emission condition of an effective value 95V or less of the voltage of the AC power supply 3; One light emission condition is determined. The light emission condition determination unit 17 sends the determined light emission condition to the light emission instruction unit 18, and sets the light emission condition in the light emission instruction unit 18 (step S8).

  The light emission instructing unit 18 controls the light emission of the flash discharge tube 2 based on the set light emission conditions (step S9). That is, the light emission instruction unit 18 controls the on timing and the off timing of the switching element 9 based on the set light emission conditions. Specifically, when the effective value of the voltage of the AC power supply 3 is higher than a reference value (for example, 105 V or more), the light emission instructing unit 18 switches the switching element 9 earlier than the reference time as shown in FIG. Control to turn off (reduce the light emission time). If the effective value of the voltage of the AC power supply 3 is a reference value (for example, AC95V to AC105V), the switching element 9 is controlled to be turned off at the reference time as shown in FIG. If the effective value of the voltage 3 is lower than the reference value (for example, 95 V or less), as shown in FIG. 4C, the switching element 9 is turned off later than the reference time (the light emission time is lengthened). To control. By controlling in this way, the light emission instructing unit 18 controls the amount of light emitted from the flash discharge tube 2 to be close to a constant amount regardless of the effective value of the voltage of the AC power supply 3. The charging unit 4 is recharged by the AC power source 3 for each light emission of the flash discharge tube 2 (step S10). And the light emission instruction | indication part 18 makes the flash discharge tube 2 light-emit again (step S11). The light emission instructing unit 18 causes the flash discharge tube 2 to emit light a predetermined number of times based on the light emission conditions for causing the flash discharge tube 2 to emit light (step S12). Thereby, the light emission instruction | indication part 18 makes the flash discharge tube 2 light-emit the light quantity (total light quantity) required in order to harden resin.

The light emission condition is determined based on the above. In the first embodiment, the light emission condition determining unit 17 determines the light emission conditions from a table showing a plurality of different light emission timings of the flash discharge tube 2 in accordance with the magnitude of the effective value of the voltage of the AC power supply 3. In the embodiment, the light emission condition determination unit 17 sets the light emission condition related to the light emission timing using a table in which information for causing the flash discharge tube 2 to emit light at a constant light emission timing is set regardless of the effective value of the voltage of the AC power supply 3. decide. Then, the light emission condition determination unit 17 identifies the light emission condition (the protection resistor to be used) related to the protection resistor from the table in which information for identifying the protection resistors 20, 21, and 22 to be switched is set for the resistance connection unit 23. (Emission condition) is determined. As shown in FIG. 6, the light emission condition determining unit 17 is connected to each of the light emission instruction unit 18 and the resistance connection unit 23, and sets the light emission condition related to the light emission timing of the flash discharge tube 2 in the light emission instruction unit 18. The light emission condition related to the protective resistance to be used is set in the resistance connection portion 23. In the present embodiment, the light emission condition determination unit 17 uses the same light emission condition as the light emission timing when the effective value of the voltage of the AC power supply 3 is 95 V in the first embodiment as the light emission condition indicating the light emission timing ( The number of times of light emission, the time of one light emission, and the light emission interval) are determined as the light emission conditions related to the light emission timing.

  Next, the effect | action about the resin hardening apparatus 1 which concerns on this embodiment is demonstrated using the flowchart of FIG.

  As shown in FIG. 7, after connecting the resin curing device 1 to the AC power supply 3, the light emitting button (not shown) is turned on, so that the charging unit 4 starts charging from the AC power supply 3 (Step S <b> 10). ). At this time, the resistance connection unit 23 connects the protection resistor to the second capacitor 13 in advance so as to use the protection resistor 20 having the resistance value of 8Ω (the protection resistor having the lowest resistance value). The charging unit 4 is charged with power obtained by boosting the effective value of the voltage of the AC power supply 3 by a half-wave voltage doubler rectifier circuit using the protective resistor 20 having a resistance value of 8Ω. The voltage dividing resistors 6 and 7 are energized by the electric power charged in the charging unit 4 and divide the voltage according to the charging voltage of the charging unit 4 (second capacitor 13).

  The light emission control unit 5 waits until a predetermined time (first predetermined time, for example, 500 msec) elapses (step S20). And the light emission control part 5 measures the voltage of the voltage dividing resistor 7 after progress of predetermined time. Specifically, the A / D conversion unit 14 sends a monitor voltage obtained by digitally converting the voltage of the voltage dividing resistor 7 to the voltage comparison unit 15. The voltage comparison unit 15 acquires the monitor voltage value converted by the A / D conversion unit 14. (Step S30).

  The light emission controller 5 further measures the voltage of the voltage dividing resistor 7 after a predetermined time (second predetermined time, for example, 50 msec) has elapsed (step S40) (step S50). Specifically, the A / D conversion unit 14 sends a monitor voltage obtained by digitally converting the voltage of the voltage dividing resistor 7 to the voltage comparison unit 15. The voltage comparison unit 15 acquires the monitor voltage value converted by the A / D conversion unit 14 and compares it with the monitor voltage value acquired immediately before (the monitor voltage value acquired before the second predetermined time). As shown in FIG. 9A and FIG. 9B, the amount of increase in the charging voltage of the charging unit 4 becomes smaller as it approaches the maximum voltage that can be charged using the AC power supply 3, so that the voltage comparing unit 15 As a result, when the amount of increase in the voltage value of the voltage dividing resistor 7 becomes equal to or less than the threshold value, it is determined that the charging of the charging unit 4 is completed, and the monitor voltage value acquired last is sent to the voltage specifying unit 16 (step S60 YES) ).

  On the other hand, as a result of the comparison, the voltage comparison unit 15 determines that the charging of the charging unit 4 is not completed when the amount of increase in the charging voltage exceeds the threshold, and further determines a predetermined time (second predetermined time, For example, after 50 msec), the monitor voltage value is obtained again from the A / D converter 14 and the comparison of the monitor voltage value is repeated until the increase amount of the monitor voltage value becomes equal to or less than the threshold (NO in step S60).

  The voltage specifying unit 16 specifies the effective value of the voltage of the AC power supply 3 based on the monitor voltage value sent from the voltage comparing unit 15 (step S70). The voltage specifying unit 16 sends the effective value of the specified voltage of the AC power supply 3 to the light emission condition determining unit 17.

  The light emission condition determination unit 17 determines a light emission condition suitable for the effective value of the voltage of the specified AC power supply 3 based on a table in which a plurality of light emission conditions of the flash discharge tube 2 are set. Specifically, the light emission condition determination unit 17 is based on a table in which a plurality of light emission conditions of the flash discharge tube are set, and the charging unit 4 (with a protective resistance that matches the effective value of the voltage of the specified AC power supply 3. Decide to charge the capacitor). The light emission condition determination unit 17 sets the protection resistor indicated by the light emission condition in the resistance connection unit 23 to be connected to the second capacitor 13 in order to charge the charging unit 4 with the protection resistance indicated by the determined light emission condition ( Step S80). In addition, the light emission condition determination unit 17 reads the light emission condition indicating the timing for causing the flash discharge tube 2 to emit light from the table. The light emission condition determination unit 17 determines to cause the flash discharge tube 2 to emit light under the read light emission condition. Then, the light emission condition determination unit 17 sets a light emission condition indicating the timing for causing the flash discharge tube 2 to emit light in the light emission instruction unit 18.

  The light emission instructing unit 18 starts light emission of the flash discharge tube 2 in accordance with the set light emission conditions (step S90).

  Before the flash discharge tube 2 starts light emission for the second time (after the flash discharge tube 2 finishes the first light emission), the resistance connection portion 23 is based on the light emission conditions set by the light emission condition determination unit 17. Any one of the protective resistors 20, 21 and 22 is connected to the second capacitor 13 (step S100). For example, when the voltage of the specified AC power supply 3 is 95 V or less, the resistance connection unit 23 uses the protective resistor 20 as it is based on the light emission condition for connecting the protective resistor 20 having a resistance value of 8Ω to the second capacitor 13. 2 Connect to capacitor 13. When the voltage of the specified AC power supply 3 is between 105V and 95V, the resistance connection unit 23 has a resistance value based on the light emission condition for connecting the protective resistor 21 having a resistance value of 13.5Ω to the second capacitor 13. The protective resistor 21 having a resistance value of 13.5Ω is connected to the second capacitor 13 by switching from the protective resistor 20 of 8Ω. When the voltage of the specified AC power supply 3 is 105 V or more, the resistance connection unit 23 is based on the light emission condition for connecting the protection resistor 22 having a resistance value of 19Ω to the second capacitor 13 and the protection resistor 20 having a resistance value of 8Ω. And the protective resistor 22 having a resistance value of 19Ω is connected to the second capacitor 13. Charging unit 4 (second capacitor 13) is recharged using the connected protective resistor (step S110). Then, when the effective value of the voltage of the AC power supply 3 is 110 V, the charging unit 4 (second capacitor 13) has the relationship between the voltage and time shown in FIG. As shown in FIG. Further, when the effective value of the voltage of the AC power supply 3 is 100 V, the charging unit 4 (second capacitor 13) has the relationship between the voltage and time shown in FIG. As shown in FIG. Further, when the effective value of the voltage of the AC power supply 3 is 90 V, the charging unit 4 (second capacitor 13) has the relationship between the voltage and time shown in FIG. As shown in FIG. In this way, the voltage charged in the charging unit 4 is approximated to a constant value.

  The light emission instructing unit 18 controls the second light emission of the flash discharge tube 2 in accordance with the set light emission conditions (step S120). Then, the light emission instructing unit 18 causes the flash discharge tube 2 to emit light a predetermined number of times based on the light emission condition indicating the timing for causing the flash discharge tube 2 to emit light (step S130).

  As described above, the resin curing device 1 according to the embodiment includes the flash discharge tube 2, the charging unit 4 that is charged by the AC power source 3 for each light emission of the flash discharge tube 2, and the charging unit 4. A light emission control unit 5 for controlling the power supply to the flash discharge tube 2, and the light emission control unit 5 specifies the effective value of the voltage of the AC power source 3 based on the charging voltage of the charging unit 4 and specifies In accordance with the effective value of the voltage of the AC power supply 3, the light emission conditions are determined so that the total light emission amount of the flash discharge tube 2 becomes a light amount necessary for curing the resin, and the flash discharge tube 2 is directed toward the flash discharge tube 2. The power supply is controlled.

  According to this configuration, the charging unit 4 is charged by the AC power supply 3. The flash discharge tube 2 emits light by the electric power charged in the charging unit 4. After the flash discharge tube 2 emits light only once, the charging unit 4 is charged by the AC power source 3. In the resin curing device 1, the charging of the charging unit 4 and the light emission of the flash discharge tube 2 are repeated to obtain continuous light emission of the flash discharge tube 2. Thereby, the amount of light emission is accumulated, and the amount of light necessary for the resin to cure can be obtained.

  Here, when the light emission control unit 5 supplies power to the flash discharge tube 2, the light emission control unit 5 specifies the effective value of the voltage of the AC power supply 3 from the charging voltage charged in the charging unit 4. The light emission control unit 5 determines the light emission conditions corresponding to the effective value of the flash discharge tube 2 such that the total light emission amount necessary for curing the resin is obtained. As a result, the light emission control unit 5 controls power supply to the flash discharge tube 2 under the determined light emission conditions. Thereby, even if the voltage of the AC power supply 3 is low, the total light emission amount at the time when the continuous light emission of the flash discharge tube 2 is completed is not reduced. Even when the voltage of the AC power supply 3 is high, the total light emission amount is not too much.

  Further, as another aspect of the resin curing device 1 according to the above embodiment, the light emission control unit 5 uses the charging voltage of the charging unit 4 as a half cycle of the AC cycle of the AC power supply 3 when the flash discharge tube 2 is charged before the first light emission. By measuring multiple times with the above interval, the amount of voltage increase during each measurement is acquired, and the effective value of the voltage of the AC power supply 3 is specified in a state where the amount of voltage increase is below a predetermined threshold. Also good.

  According to such a configuration, since the amount of voltage increase per cycle of AC decreases as the charging is completed, charging with the current voltage of the AC power supply 3 is completed when the flash discharge tube 2 is charged before the first light emission. Since the effective value of the voltage of the AC power supply 3 is specified when the voltage increase amount is equal to or less than a threshold that can be determined, the light emission control unit determines the completion of charging of the charging unit, and then determines the voltage of the AC power supply. The effective value can be specified correctly. Further, the charging time at the current voltage of the AC power supply 3 can be provided without providing a long charging standby time in accordance with the initial charging time when the voltage of the normal AC power supply 3 is changed to the lowest voltage that can be assumed. The completion of charging can be determined according to the above. Thereby, time until the light emission control part 5 supplies electric power to the flash discharge tube 2 can be shortened.

  As another aspect of the resin curing device 1 according to the above-described embodiment, the light emission control unit 5 includes the flash discharge tube 2 when the effective value of the voltage of the specified AC power supply 3 is higher than a reference value corresponding to the standard voltage. When the light emission time per time is shorter than the reference time corresponding to the standard voltage, and the effective value of the voltage of the specified AC power supply 3 is lower than the reference value corresponding to the standard voltage, one of the flash discharge tube 2 The light emission time per time may be longer than the reference time corresponding to the standard voltage.

  According to such a configuration, when the effective value of the voltage of the AC power supply 3 is higher than the reference value corresponding to the standard voltage, the maximum voltage of the power charged in the charging unit 4 is higher than the reference value corresponding to the standard voltage. Become. Therefore, the actual light emission start time of the flash discharge tube 2 is earlier than when the effective value of the voltage of the AC power supply 3 is lower than the reference value corresponding to the standard voltage. Therefore, when the effective value of the voltage of the AC power supply 3 is higher than the reference value corresponding to the standard voltage, the light emission control unit 5 sets the light emission time per flash discharge tube 2 from the reference time corresponding to the standard voltage. Also shorten it. Conversely, when the effective value of the voltage of the AC power supply 3 is lower than the reference value corresponding to the standard voltage, the light emission time per flash discharge tube 2 is set longer than the reference time corresponding to the standard voltage. As a result, even if there is a difference in the effective value of the voltage of the AC power source 3, the single light emission amount of the flash discharge tube 2 can be made constant. As a result, the total light emission amount due to the continuous light emission of the flash discharge tube 2 can be reduced. Can be constant.

  As another aspect of the resin curing device 1 according to the above-described embodiment, the light emission control unit 5 includes the flash discharge tube 2 when the effective value of the voltage of the specified AC power supply 3 is higher than a reference value corresponding to the standard voltage. When the effective value of the voltage of the specified AC power supply 3 is lower than the reference value corresponding to the standard voltage, the total number of flashes of the flash discharge tube 2 is standardized. You may increase more than the reference | standard frequency | count corresponding to a voltage.

  According to such a configuration, when the effective value of the voltage of the specified AC power supply 3 is higher than the reference value corresponding to the standard voltage, the number of times of light emission of the flash discharge tube 2 is reduced from the reference number corresponding to the standard voltage. The total light emission amount by continuous light emission of the flash discharge tube 2 can be made constant. On the contrary, when the effective value of the voltage of the specified AC power supply 3 is lower than the reference value corresponding to the standard voltage, the flash discharge tube 2 emits more times than the reference number corresponding to the standard voltage. The total light emission amount by continuous light emission of the tube 2 can be made constant.

  As another aspect of the resin curing device 1 according to the above embodiment, a capacitor (second capacitor 13) for charging power supplied to the flash discharge tube 2 and a protective resistor connected to the capacitor (second capacitor 13) 20, 21, 22, a plurality of protective resistors 20, 21, 22 having different resistance values, and protective resistors 20, 21, 22 according to the effective value of the voltage of the AC power supply 3 specified by the light emission control unit 5 You may have the resistance connection part 23 selectively connected with respect to a capacitor | condenser (2nd capacitor | condenser 13).

  According to such a configuration, the resistance connection unit 23 selectively connects the protective resistors 20, 21, and 22 having resistance values corresponding to the specified voltage value of the AC power supply 3 to the capacitor (second capacitor 13). The charging voltage of (second capacitor 13) is approximate. Thus, even when the effective value of the voltage of the AC power supply 3 is lower than the reference value corresponding to the standard voltage, the total light emission amount at the time of completion of continuous light emission of the flash discharge tube 2 is not reduced, and the AC power supply Even when the effective value of the voltage 3 is higher than the reference value corresponding to the standard voltage, the total light emission amount is not too large.

  As another aspect of the resin curing device 1 according to the above embodiment, the light emission control unit 5 includes a voltage specifying unit 16 that specifies the effective value of the voltage of the AC power supply 3 from the charging voltage of the charging unit 4, and the flash discharge tube 2. A light emission condition determining unit 17 that determines the light emission condition of the flash discharge tube 2 using the effective value of the voltage of the AC power supply 3 specified by the voltage specifying unit 16 from a table in which a plurality of light emission conditions are set, and the light emission condition You may have the light emission instruction | indication part 18 which makes the flash discharge tube 2 light-emit according to the light emission conditions determined by the determination part 17. FIG.

  According to such a configuration, the voltage specifying unit 16 specifies the effective value of the voltage of the AC power supply 3 using the charging unit 4. Then, the voltage specifying unit 16 sends the effective value of the voltage of the specified AC power supply 3 to the light emission condition determining unit 17. The light emission condition determination unit 17 determines the light emission condition from a table in which a plurality of light emission conditions for the flash discharge tube 2 are set, using the effective value of the voltage of the specified AC power supply 3. The light emission condition determination unit 17 sets the determined light emission condition in the light emission instruction unit 18. The light emission instruction unit 18 causes the flash discharge tube 2 to emit light in accordance with the light emission conditions set by the light emission condition determination unit 17. Thereby, even if there is a difference in the effective value of the voltage of the AC power supply 3, the light emission control unit 5 can cause the flash discharge tube 2 to emit a light amount appropriate for curing the photocurable resin.

  Further, as another aspect of the resin curing device 1 according to the above embodiment, the light emission control unit 5 includes a voltage specifying unit 16 that specifies the effective value of the voltage of the AC power supply 3 from the charging voltage of the charging unit 4, and the voltage specifying unit. A table in which a plurality of light emission conditions for identifying protective resistors 20, 21, and 22 that are selectively connected to the capacitor (second capacitor 13) is set using the effective value of the voltage of the AC power supply 3 specified by 16 A light emission condition determining unit 17 that determines the light emission conditions related to the connected protective resistors 20, 21, and 22 and sets the light emission conditions related to the connected protective resistors 20, 21, and 22 to the resistance connection unit 23. And the resistance connection part 23 may connect the protection resistance 20, 21, and 22 to a capacitor | condenser based on the set light emission conditions.

  According to this configuration, the voltage specifying unit 16 specifies the effective value of the voltage of the AC power supply 3 using the charging voltage of the charging unit 4. Then, the voltage specifying unit 16 sends the effective value of the voltage of the specified AC power supply 3 to the light emission condition determining unit 17. The light emission condition determining unit 17 uses a specified effective value of the voltage of the AC power supply 3 to determine a plurality of light emission conditions for identifying the protective resistors 20, 21, and 22 that are selectively connected to the capacitor (second capacitor 13). From the set table, the connected protective resistors 20, 21, 22 are determined as the light emission conditions. The light emission condition determination unit 17 sets the light emission conditions related to the protection resistors 20, 21, and 22 to be connected to the resistance connection unit 23. And the resistance connection part 23 connects the protection resistance 20,21,22 selected based on the set light emission conditions to a capacitor | condenser (2nd capacitor | condenser 13). Thereby, the light emission control part 5 can make the total light emission amount of the flash discharge tube 2 constant even if the voltage value of the AC power supply 3 is different.

  Then, according to the resin curing device 1 according to the present embodiment, even if the effective value of the voltage of the AC power supply 3 varies with respect to the standard voltage, the amount of light that the flash discharge tube 2 emits once can be reduced. Can be constant. Thereby, even if the effective value of the voltage of the AC power supply 3 is lower than the standard voltage, it is possible to prevent the amount of light necessary for curing the resin from being obtained due to the decrease in the total light emission amount. Even if the effective voltage value of the AC power supply 3 is higher than the standard voltage, the total light emission amount is not too large.

  The resin curing device 1 according to the above embodiment is not limited to the above embodiment. Of course, various modifications can be made without departing from the scope of the present invention.

  For example, in the resin curing device 1 according to the first embodiment, the number of discharges of the flash discharge tube 2 has been described as being constant, but the light emission control unit 5 has the effective value of the specified voltage of the AC power supply 3 corresponding to the standard voltage. When it is higher than the reference value, the light emission time per flash discharge tube 2 is made shorter than the reference time corresponding to the standard voltage, and the effective value of the voltage of the specified AC power supply 3 corresponds to the standard voltage. When the time is lower, the light emission time per one time of the flash discharge tube 2 may be longer than the reference time corresponding to the standard voltage. Specifically, the light emission condition determination unit 17 may determine the light emission condition using a table in which the light emission condition for changing the number of times of light emission is set according to the effective value of the voltage of the AC power supply 3. The light emission instructing unit 18 can make the total light emission amount until the end of light emission constant by causing the flash discharge tube 2 to emit light according to the light emission conditions set by the light emission condition determining unit 17.

  Further, the resin curing device 1 according to the first embodiment may change the light emission time per time of the flash discharge tube 2 as the continuous light emission proceeds in the continuous light emission under the selected light emission conditions.

The light emission condition may be determined according to the effective value of the voltage of the AC power supply 3 from a table having different times.

However, the resin curing device 1 has a configuration having a plurality of flash discharge tubes 2. May be. At this time, the light emission condition determining unit 17 may determine the light emission conditions for causing the plurality of flash discharge tubes 2 to emit light from the table as the effective value of the voltage of the AC power supply 3 is lower.

  Moreover, although the resistance connection part 23 which concerns on 2nd Embodiment is a structure provided in the charging part 4, the structure provided in the light emission control part 5 may be sufficient.
