The supply amount to the purge air supply path 70 is controlled by a purge air supply valve 71 (hereinafter simply referred to as a valve 71) that changes the flow path cross-sectional area of the purge air supply path 70. The purge air supply path 70 is connected to the storage box 50, and the purge air that has flowed out of the heat exchanger 67 is introduced into the storage box 50. In the purge air supply path 70, an air heater 72 for heating the purge air is disposed between the valve 71 and the heat exchanger 67. The heat exchanger 67 is supplied with purge air heated by the air heater 72.

  In addition to the purge air supply path 70, the dry air supply source 69 supplies dry air generated by the dry air supply source 69 to the second supply path 75 as a temperature rising gas that is a second medium. The second supply path 75 is branched at the branching section 76 into a second supply path 75A and a second supply path 75B.

  When the target temperature of the electronic component T is the first target temperature, for example, −45 ° C., the control device 85 performs the cooling operation that is the first temperature adjustment state for cooling the accommodation pocket. In addition, when the target temperature of the electronic component T is switched from the first target temperature to the second target temperature that is a room temperature such as 18 ° C., the control device 85 is in a second temperature adjustment state in which the accommodation pocket is returned to the room temperature. The normal temperature return operation is performed.

  As shown in FIG. 3, the control device 85 is electrically connected to a temperature adjustment unit driving unit 87 having a valve driving unit 87a, a heater driving unit 87b, and an air heater driving unit 87c.

  First, regarding the cooling operation, driving modes of each valve, each heater, and each air heater by the valve driving unit 87a, the heater driving unit 87b, and the air heater driving unit 87c will be described.

  In the cooling operation, the valve drive unit 87a sets the temperature of the accommodation pockets 17A and 17B to the first target temperature based on the first target temperature input from the control device 85 and the detection values of the temperature sensors 63A and 63B. As described above, the opening / closing time of each of the valves 59A and 59B is set, and a signal indicating the opening / closing time is output to each of the valves 59A and 59B. The valves 59A and 59B adjust the supply amount of nitrogen gas to each of the medium flow paths 58A and 58B by opening and closing according to the input signal. Further, the valve driving unit 87a outputs a signal indicating that the valve 78 is maintained in the closed state to the valve 78. In addition, the valve drive unit 87 a outputs a signal indicating that the opening degree of the valve 71 is maintained at the maximum opening degree to the valve 71.

  In the cooling operation, the heater driving unit 87b sets the temperature of the storage pockets 17A and 17B to the target temperature based on the first target temperature input from the control device 85 and the temperature input from the temperature sensors 63A and 63B. As described above, drive power is generated for each of the heaters 62A and 62B, and the drive power is output to the heaters 62A and 62B to drive the heaters 62A and 62B.

  In the cooling operation, the air heater driving unit 87 c drives only the air heater 72 among the air heaters 72 and 79. Based on the opening / closing time of the valves 59A and 59B, the air heater driving unit 87c is adapted to the air heater 72 so that the nitrogen gas and the purge air become normal temperature by heat exchange between the nitrogen gas and the purge air in the heat exchanger 67. Drive power is generated, and the drive power is output to the air heater 72 to drive the air heater 72.

  Next, regarding the normal temperature recovery operation, driving modes of each valve, each heater, and each air heater by the valve driving unit 87a, the heater driving unit 87b, and the air heater driving unit 87c will be described.

  In the normal temperature recovery operation, the valve drive unit 87a outputs a signal indicating that the valves 59A and 59B are maintained in the closed state to the valves 59A and 59B. In addition, the valve drive unit 87 a outputs a signal indicating that the opening degree of the valve 78 is the maximum opening degree to the valve 78. Further, the valve drive unit 87 a outputs a signal indicating that the opening degree of the valve 71 is set to the maximum opening degree to the valve 71.

  In the normal temperature recovery operation, the heater driving unit 87b sets the temperature of the accommodation pockets 17A and 17B to the second based on the second target temperature input from the control device 85 and the temperature input from the temperature sensors 63A and 63B. Drive power is generated for each of the heaters 62A and 62B so as to reach the target temperature, and the drive power is output to the heaters 62A and 62B to drive the heaters 62A and 62B.

  In the normal temperature recovery operation, the air heater driving unit 87c drives both the air heaters 72 and 79. The air heater driving unit 87c generates driving power for the air heater 79 so that the temperature rising gas supplied to the medium flow paths 58A and 58B has a predetermined temperature higher than the second target temperature. The air heater driving unit 87 c outputs the generated driving power to the air heater 79 to drive the air heater 79.

  Further, the air heater driving unit 87c is configured to perform a heat exchange between the temperature rising gas and the purge air in the heat exchanger 67 based on the detection values of the temperature sensors 63A and 63B, so that both the temperature rising gas and the purge air have a temperature equal to or higher than normal temperature. The drive power is generated for the air heater 72 so that The air heater driving unit 87 c outputs the generated driving power to the air heater 72 to drive the air heater 72.

  That is, in the cooling operation and the normal temperature recovery operation, the temperature adjustment unit driving unit 87, as shown in FIG. 4, the nitrogen supply valves 59A and 59B, the temperature rising gas supply valve 78, the purge air supply valve 71, and the heaters 62A and 62B. The driving mode of the air heaters 72 and 79 is changed.

  As with the temperature adjustment unit drive unit 87, the temperature adjustment unit corresponding to the other storage pocket 17 of the supply shuttle plate 15a, the storage pocket 18 of the supply shuttle plate 16a, and the inspection socket 14a of the test head 14 is used. However, a temperature adjustment unit drive section is provided for each temperature adjustment unit. That is, the control device 85 controls the temperature adjustment units in a manner independent of each other.

[Temperature adjustment unit during cooling operation in the first embodiment]
Next, the temperature adjustment unit during the cooling operation will be described with reference to FIG. As described above, in the cooling operation in the handler and component inspection device of the first embodiment, the valves 59A, 59B, 71 are controlled to open and close, and the valve 78 is controlled to be closed. In the cooling operation, the valve 78 is closed and the flow of nitrogen gas from the first supply path 57A, 57B to the second supply path 75 is suppressed by the check valves 80A, 80B. No fluid flows through the supply paths 75, 75A, and 75B. Therefore, in FIG. 5, the 2nd supply path 75, 75A, 75B is shown with the dotted line.

  As shown in FIG. 5, the liquid nitrogen supplied from the storage tank 55 to the first supply passages 57 </ b> A and 57 </ b> B eventually flows into the vaporization container 60. The liquid nitrogen that has flowed into the vaporization container 60 is transferred to nitrogen gas in the vaporization container 60, and then flows into the medium flow paths 58A and 58B to cool the storage pockets 17A and 17B.

  The nitrogen gas discharged from the medium flow paths 58A and 58B to the discharge paths 64A and 64B joins at the connection portion 65 and then flows into the heat exchanger 67. In addition to the nitrogen gas, a purge gas heated by the air heater 72 and having a temperature higher than that of the nitrogen gas flows into the heat exchanger 67. The nitrogen gas that has flowed into the heat exchanger 67 is heated to room temperature by heat exchange with the purge gas and then introduced into the storage box 50. The purge air that has flowed into the heat exchanger 67 is cooled to room temperature by heat exchange with nitrogen gas and then introduced into the storage box 50.

  In such a cooling operation, the controller 85 determines the opening / closing times of the valves 59A and 59B and the driving power output to the heaters 62A and 62B so that the temperature input from the temperature sensors 63A and 63B becomes the first target temperature. To control. Further, the control device 85 controls the driving power output to the air heater 72 so that the nitrogen gas and the purge air introduced into the storage box 50 are at room temperature while controlling the valve 71 to the maximum opening.

[Temperature adjustment unit during normal temperature recovery operation in the first embodiment]
Next, the temperature adjustment unit for normal temperature return operation will be described with reference to FIG. As described above, in the normal temperature recovery operation in the handler and the parts inspection apparatus of the first embodiment, the valves 59A and 59B are controlled to be closed, and the openings of the valves 71 and 78 are controlled to the maximum opening. In the normal temperature recovery operation, nitrogen as the first medium does not flow through the first supply passages 57A and 57B from the storage tank 55 to the connection portions 77A and 77B. Therefore, in FIG. 6, the common path 56 and a part of the first supply paths 57A and 57B are indicated by dotted lines.

  As shown in FIG. 6, the temperature rising gas supplied from the dry air supply source 69 to the second supply path 75 is heated to a temperature higher than the second target temperature by the air heater 79, and then in the branching section 76. The flow is divided into the second supply paths 75A and 75B. The temperature rising gas that has flowed into the second supply paths 75A and 75B flows into the first supply paths 57A and 57B at the connection portions 77A and 77B, and then flows into the medium flow paths 58A and 58B. The temperature rising gas flowing into the medium flow paths 58A and 58B is discharged into the discharge paths 64A and 64B after heating the accommodation pockets 17A and 17B. That is, the storage pockets 17A and 17B that are at the first target temperature are directly heated by the temperature rising gas flowing through the medium flow paths 58A and 58B in addition to the heaters 62A and 62B.

  The temperature rising gas discharged from the medium flow paths 58A and 58B to the discharge paths 64A and 64B joins at the connection portion 65 and then flows into the heat exchanger 67. In addition to the nitrogen gas, purge gas adjusted to a temperature equal to or higher than normal temperature by the air heater 72 flows into the heat exchanger 67. The nitrogen gas flowing into the heat exchanger 67 is adjusted to a temperature equal to or higher than normal temperature by heat exchange with the purge gas, and then introduced into the storage box 50. Further, the purge air that has flowed into the heat exchanger 67 is maintained at a temperature equal to or higher than normal temperature even after heat exchange with nitrogen gas, and is then introduced into the storage box 50.

  In such a normal temperature recovery operation, the control device 85 outputs to the air heater 79 while controlling the opening degree of the valve 78 to the maximum opening degree so that the temperature input from the temperature sensors 63A and 63B becomes the second target temperature. The driving power to be output and the driving power output to the heaters 62A and 62B are controlled. Further, the control device 85 controls the driving power output to the air heater 72 so that the nitrogen gas and the purge air introduced into the storage box 50 are equal to or higher than normal temperature while controlling the valve 71 to the maximum opening.

  When the detected values of the temperature sensors 63A and 63B eventually reach the second target temperature, the driving of the heaters 62A and 62B and the air heaters 72 and 79 is stopped, and the normal temperature recovery operation ends. Thereby, the temperature of the storage pockets 17A and 17B is switched from the first target temperature to the second target temperature, and accordingly, the temperature of the electronic component T stored in the storage pockets 17A and 17B is also changed from the first target temperature to the second target temperature. Switch to temperature. The valves 71 and 78 are maintained in the open state even after the normal temperature return operation is completed. Thereby, the dry air is continuously supplied into the storage box 50, and the inside of the storage box 50 is maintained in a dry state.

[Operation of Handler and Component Inspection Device of First Embodiment]
Next, the operation of the handler and the component inspection apparatus in the first embodiment will be described.
In the handler and the component inspection apparatus of the first embodiment, when the target temperature of the electronic component T is switched from the first target temperature to the second target temperature, the above-described normal temperature return operation is performed. When the normal temperature recovery operation is started, the medium supplied to the medium flow paths 58A and 58B is switched from nitrogen as the first medium to the temperature rising gas as the second medium. The accommodation pockets 17A and 17B that have reached the first target temperature are heated by the temperature raising gas until the second target temperature is reached.

  Therefore, for example, each of the storage pockets 17A and 17B has the second target temperature as compared with a case where the apparatus itself waits until the storage pockets 17A and 17B reach room temperature or when dry air of normal temperature is supplied to the medium flow paths 58A and 58B. It is possible to reduce the time required to switch to

  In addition, since the check valves 80A and 80B are provided in the second supply passages 75A and 75B, part of the nitrogen gas flows into the air heater 79 during the cooling operation, and the air heater 79 is caused by the nitrogen gas. Can be prevented from being cooled. As a result, the temperature of the air heater 79 at the start of the normal temperature recovery operation is increased as compared with the case where a part of the nitrogen gas flows into the air heater 79. As a result, since the temperature rising gas having a temperature higher than the second target temperature is supplied to the first supply paths 57A and 57B at an early stage, each storage pocket 17A and 17B is switched to the second target temperature. The time required can be further reduced.

  A valve 78 is disposed in the second supply path 75 on the upstream side of the air heater 79. Here, if a part of the nitrogen gas flows into the valve 78, it is necessary to set the design temperature of the valve 78 to a temperature lower than the temperature of the nitrogen gas. That is, the design temperature of the valve 78 can be set high by inhibiting the inflow of nitrogen gas to the valve 78 by the check valves 80A and 80B. As a result, the degree of freedom regarding the members constituting the valve 78 can be increased.

  Further, the nitrogen gas and the temperature rising gas discharged from the medium flow paths 58A and 58B to the discharge path 64A are introduced into the storage box 50. Nitrogen gas is obtained by vaporizing liquid nitrogen and has a moisture content close to 0, and the temperature rising gas is also dry air, and has a lower moisture content than air around the component inspection apparatus. Therefore, when the nitrogen gas and the temperature rising gas are introduced into the storage box 50, the storage box 50 is filled with a gas having a low moisture content. As a result, it is possible to suppress the occurrence of condensation in the storage box 50.

  On the other hand, since the nitrogen gas discharged from the medium flow paths 58A and 58B to the discharge paths 64A and 64B cools the flow path of the nitrogen gas including the storage pockets 17A and 17B, compared with immediately after flowing out from the vaporization container 60. However, the temperature is still lower than room temperature. Further, since the temperature rising gas discharged from the medium flow paths 58A and 58B to the discharge paths 64A and 64B heats the flow path of the nitrogen gas including the accommodation pockets 17A and 17B, the temperature rises to a temperature lower than room temperature. It may have declined. If such nitrogen gas or temperature rising gas is introduced into the storage box 50, the temperature in the storage box 50 may vary depending on the temperature of the storage box 50 even though a gas having a low water content is supplied to the storage box 50. There is a possibility that condensation will occur in the storage box 50. In this respect, the temperature of the nitrogen gas and the temperature raising gas introduced into the storage box 50 is adjusted to a temperature equal to or higher than the normal temperature by heat exchange with the purge gas in the heat exchanger 67. Therefore, it is possible to suppress the temperature in the storage box 50 from decreasing to a temperature lower than the dew point at that time, and it is possible to further suppress the occurrence of condensation in the storage box 50.

  Then, nitrogen gas for cooling the storage pockets 17A and 17B, temperature rising gas for heating the storage pockets 17A and 17B, and these as gas for preventing condensation in the storage box 50 are used. Therefore, the nitrogen gas and the temperature rising gas can be effectively used to suppress the occurrence of dew condensation in the storage box 50.

  In addition, the second supply path 75 is branched into second supply paths 75A and 75B at a branching portion 76 on the downstream side of the air heater 79, and these second supply paths 75A and 75B are first supply paths 57A and 57B. It is connected to the. That is, the second supply path 75 is connected in parallel to the two first supply paths 57A and 57B on the downstream side of the air heater 79. Therefore, the dry air supply source 69, the valve 78, and the air heater 79 can be shared when supplying the temperature rising gas to the two first supply paths 57A and 57B. As a result, the configuration of the second supply path can be simplified as compared with the case where the dry air supply source 69, the valve 78, and the air heater 79 are provided in each of the two second supply paths 75A and 75B.

As described above, according to the handler and component inspection apparatus of the first embodiment, the effects listed below can be obtained.
(1) By the normal temperature return operation, the accommodation pockets 17A and 17B that are at the first target temperature can be switched to the second target temperature, and the time required to switch to the second target temperature can be shortened.

  (2) Further, since the flow path of nitrogen gas and the flow path of temperature rising gas are shared downstream of the connection portion between the first supply path and the second supply path, the flow of nitrogen gas Compared with the case where the path and the flow path of the temperature rising gas are provided separately, the configuration required for temperature switching can be simplified.

  (3) Further, since the check valve 80A, 80B prevents the inflow of nitrogen gas to the air heater 79, the time required for each of the accommodation pockets 17A, 17B to switch to the second target temperature is further reduced. Can do.

  (4) The valve 78 is disposed on the upstream side of the air heater 79 in the second supply path 75, and similarly to the air heater 79, the inflow of nitrogen gas is suppressed by the check valves 80 </ b> A and 80 </ b> B. Therefore, the freedom degree regarding the member which comprises the valve | bulb 78 can be raised.

  (5) Since the nitrogen gas used for cooling the storage pocket and the temperature rising gas used for heating the storage pocket are introduced into the storage box 50, the moisture content of the gas filling the storage box 50 may be reduced. it can. As a result, it is possible to suppress the occurrence of condensation in the storage box 50.

  (6) A heat exchanger 67 for adjusting the temperature of the nitrogen gas and the temperature rising gas discharged from the medium flow paths 58A and 58B is disposed in the discharge path 64A. As a result, the temperature in the storage box 50 can be prevented from lowering to a temperature lower than the dew point, and the occurrence of condensation in the storage box 50 can be further suppressed.

  (7) Nitrogen gas used for cooling the storage pocket, temperature rising gas used for heating the storage pocket, and these are used as gas for preventing condensation in the storage box 50. Therefore, the nitrogen gas and the temperature rising gas can be effectively used to suppress the occurrence of dew condensation in the storage box 50.

  (8) The second supply path 75 is connected in parallel to the two first supply paths 57A and 57B on the downstream side of the air heater 79. That is, the temperature rising gas can be supplied to the two second supply passages 75A and 75B by one dry air supply source 69 and one valve 78. As a result, the configuration of the second supply path can be simplified.

  (9) Since the number of installed air heaters in the second supply path can be reduced as compared with the case where the air heater 79 is provided in each of the two second supply paths 75A and 75B, the second The configuration of the supply path can be further simplified.

  (10) Since the check valve 68 is disposed in the discharge path 64A, it is possible to suppress the occurrence of condensation and icing in the nitrogen gas flow path upstream of the check valve 68.

  (11) A check valve 66A is disposed in the discharge path 64A, and a check valve 66B is disposed in the discharge path 64B. Thereby, it is possible to further suppress the occurrence of condensation or icing in the nitrogen gas flow path upstream of these check valves 66A and 66B.

[Configuration of Temperature Adjustment Unit in Second Embodiment]

The first medium cools the accommodation pocket indirectly through the temperature adjustment medium. Similarly, the second medium also indirectly heats the accommodation pocket via the temperature adjustment medium. In the second embodiment, portions different from the first embodiment will be described in detail, and the same reference numerals are given to components having the same functions as the temperature adjustment unit in the first embodiment, and detailed description thereof will be omitted. To do.

  As shown in FIG. 7, in the temperature adjustment unit, a dry air supply source 69 supplies dry air as a temperature adjustment medium to a dry air supply path 90 that is a medium supply path. The dry air supply path 90 has an accommodation pocket via the supply side flow path 91a of the first heat exchanger 91, the dry air side flow path 92a of the second heat exchanger 92, and the dry air side flow path 93a of the third heat exchanger 93. It is connected to one end of a medium flow path 58A corresponding to 17A. The connecting path 95 connected to the other end of the medium flow path 58A is connected to one end of the medium flow path 58B corresponding to the accommodation pocket 17B via the dry air side flow path 94a of the fourth heat exchanger 94. The dry air exhaust path 96 connected to the other end of the medium flow path 58B is connected to the storage box 50 via the exhaust side flow path 91b of the first heat exchanger 91. The dry air side flow path 93a of the third heat exchanger 93 and the dry air side flow path 94a of the fourth heat exchanger 94 correspond to the first flow path.

  That is, the dry air supplied from the dry air supply source 69 as a temperature adjusting medium is supplied from the supply side passage 91a of the first heat exchanger 91, the dry air side passage 92a of the second heat exchanger 92, and the third heat exchanger 93.

First, regarding the cooling operation, driving modes of each valve and each air heater by the valve driving unit 87a and the air heater driving unit 87c will be described.
In the cooling operation, the valve drive unit 87a determines that the temperature of the storage pockets 17A and 17B is the first target temperature based on the first target temperature input from the control device 85 and the temperature input from the temperature sensors 63A and 63B. The opening / closing time of the valves 59A and 59B is set so that The valve drive unit 87a outputs a signal indicating the opening / closing time to each of the valves 59A and 59B. The valves 59A and 59B adjust the supply amount of nitrogen gas to the third and fourth heat exchangers 93 and 94 by opening and closing according to the input signal. In addition, the valve drive unit 87a sets the temperature of the accommodation pockets 17A and 17B to the first target temperature based on the first target temperature input from the control device 85 and the temperature input from the temperature sensors 63A and 63B. Thus, the opening degree of the valve 97 is set. The valve drive unit 87 a outputs a signal indicating the opening degree to the valve 97. The valve 97 adjusts the amount of dry air supplied to the medium flow paths 58A and 58B in accordance with the input signal.

  In the cooling operation, the air heater driving unit 87 c drives the air heaters 100 and 101 among the air heaters 79, 98, 100 and 101. The air heater driving unit 87c generates driving power for the air heater 101 based on the opening / closing time of the valves 59A and 59B so that the temperature of the nitrogen gas introduced into the storage box 50 becomes normal temperature. Driving power is output to the air heater 101 to drive the air heater 101. Further, the air heater driving unit 87c generates driving power for the air heater 100 based on the opening degree of the valve 97 so that the temperature of the dry air introduced into the storage box 50 becomes a normal temperature, and the driving is performed. Electric power is output to the air heater 100 to drive the air heater 100.

Next, regarding the normal temperature recovery operation, driving modes of each valve and each air heater by the valve driving unit 87a and the air heater driving unit 87c will be described.
In the normal temperature recovery operation, the valve drive unit 87a outputs a signal indicating that the valves 59A and 59B are maintained in the closed state to the valves 59A and 59B. Further, the valve drive unit 87a outputs a signal indicating that the opening degree of each of the valves 78 and 97 is maintained at the maximum opening degree to each of the valves 78 and 97.

  In the normal temperature recovery operation, the air heater driving unit 87c drives the air heaters 79, 98, 100, and 101. The air heater driving unit 87c generates driving power for the air heater 79 so that the temperature rising gas supplied to the first supply passages 57A and 57B has a predetermined temperature higher than the second target temperature. The driving power is output to the air heater 79, and the air heater 79 is driven.

  The air heater drive unit 87c generates drive power for the air heater 98 so that the dry air supplied to the first heat exchanger 91 has a predetermined temperature higher than the second target temperature, and the drive power Is output to the air heater 98 to drive the air heater 98.

  Based on the detection values of the temperature sensors 63A and 63B, the air heater driving unit 87c generates driving power for the air heater 100 so that the temperature of the dry air introduced into the storage box 50 is equal to or higher than normal temperature. At the same time, the driving power is output to the air heater 100 to drive the air heater 100.

  Based on the detection values of the temperature sensors 63A and 63B, the air heater driving unit 87c supplies driving power to the air heater 101 so that the temperature of the temperature rising gas introduced into the storage box 50 is equal to or higher than normal temperature.

  That is, in the cooling operation and the normal temperature recovery operation, the temperature adjustment unit driving unit 87, as shown in FIG. 9, the nitrogen supply valves 59A and 59B, the temperature rising gas supply valve 78, the dry air supply valve 97, and the heaters 62A and 62B. The driving mode of the air heaters 79, 98, 100, 101 is changed.

[Temperature adjustment unit during cooling operation in the second embodiment]
Next, the temperature adjustment unit during the cooling operation will be described with reference to FIG. As described above, in the cooling operation in the handler and component inspection apparatus of the second embodiment, the valves 59A, 59B, and 97 are controlled to open and close, and the valve 78 is controlled to be closed. Further, the air heaters 79 and 98 are controlled to be stopped, and the driving power of the air heaters 100 and 101 is controlled. In the cooling operation, the valve 78 is closed and the flow of nitrogen gas from the first supply path 57A, 57B to the second supply path 75 is suppressed by the check valves 80A, 80B. No fluid flows through the supply paths 75, 75A, and 75B. Therefore, in FIG. 10, the 2nd supply path 75, 75A, 75B is shown with the dotted line.

  As shown in FIG. 10, the liquid nitrogen supplied from the storage tank 55 to the first supply path 57 </ b> A flows into the gas side flow path 93 b of the third heat exchanger 93 and is transferred to nitrogen gas, and then the second. It flows into the gas side flow path 92b of the heat exchanger 92. The liquid nitrogen supplied from the storage tank 55 to the first supply path 57B flows into the gas side flow path 94b of the fourth heat exchanger 94 and is transferred to nitrogen gas, and then the gas side flow of the second heat exchanger 92. It flows into the path 92b. The nitrogen gas discharged from the gas-side flow path 92 b of the second heat exchanger 92 is heated to room temperature by the air heater 101 and then introduced into the storage box 50.

  On the other hand, the dry air supplied from the dry air supply source 69 to the dry air supply passage 90 is supplied to the supply side passage 91a of the first heat exchanger 91, the dry air side passage 92a of the second heat exchanger 92, and the third heat exchanger 93. Continuously flows into the dry air side passage 93a. The dry air is cooled stepwise by heat exchange in the first and second heat exchangers 91 and 92, and then cooled to a temperature lower than the first target temperature by heat exchange with nitrogen gas in the third heat exchanger 93. Is done. And the dry air which passed the dry air side flow path 93a of the 3rd heat exchanger 93 flows in into the medium flow path 58A, and cools the accommodation pocket 17A.

  The dry air discharged from the medium flow path 58A flows into the dry air side flow path 94a of the fourth heat exchanger 94 through the connection path 95. The dry air flowing into the fourth heat exchanger 94 has been heated by cooling the accommodation pocket 17A, but again to a temperature lower than the first target temperature by heat exchange with the nitrogen gas in the fourth heat exchanger 94. To be cooled. Then, the dry air that has passed through the fourth heat exchanger 94 flows into the medium flow path 58B and cools the accommodation pocket 17B. The dry air discharged from the medium flow path 58B to the dry air exhaust path 96 continues to pass through the exhaust-side flow path 91b of the first heat exchanger 91, and is then heated to room temperature by the air heater 100 and then stored in the storage box 50. be introduced.

  The dry air discharged from the medium flow path 58B to the dry air exhaust path 96 is at a temperature lower than room temperature, although the temperature is raised by cooling the storage pocket 17B. Therefore, in the first heat exchanger 91, the dry air before flowing into the second heat exchanger 92 is cooled using the waste heat of the dry air that has cooled the accommodation pockets 17A and 17B in advance.

  The nitrogen gas flowing into the second heat exchanger 92 is cooled by the first heat exchanger 91 even though the temperature is raised by heat exchange with dry air in the third and fourth heat exchangers 93 and 94. The temperature is lower than the temperature of the dried air. Therefore, in the second heat exchanger 92, the dry air before flowing into the third heat exchanger 93 is cooled using the waste heat of the nitrogen gas that has cooled the preceding dry air.

  The control device 85 supplies the dry air supplied to the medium flow paths 58A and 58B and the first supply paths 57A and 57B so that the temperature input from the temperature sensors 63A and 63B becomes the first target temperature. The supply amount of liquid nitrogen supplied to the heater and the drive power output to the heaters 62A and 62B are controlled. Thereby, the electronic component T accommodated in each accommodation pocket 17A, 17B is controlled to 1st target temperature.

[Temperature adjustment unit during normal temperature recovery operation in the second embodiment]
Next, the temperature adjustment unit at the time of normal temperature return operation will be described with reference to FIG. As described above, in the normal temperature recovery operation in the handler and component inspection apparatus of the second embodiment, the valves 78 and 97 are controlled to open and close and the valves 59A and 59B are controlled to be closed in the temperature adjustment unit. Further, the driving power of the air heaters 79, 98, 100, 101 is controlled. In the normal temperature recovery operation, nitrogen as the first medium does not flow through the first supply passages 57A and 57B from the storage tank 55 to the connection portions 77A and 77B. Therefore, in FIG. 11, the common path 56 and a part of the first supply paths 57A and 57B are indicated by dotted lines.

  As shown in FIG. 11, the temperature rising gas supplied from the dry air supply source 69 to the second supply path 75 is heated to a temperature higher than the second target temperature by the air heater 79, and is then 2 is divided into supply paths 75A and 75B.

  The temperature rising gas that has flowed into the second supply path 75A flows into the first supply path 57A at the connection portion 77A, and then flows into the gas-side flow path 93b of the third heat exchanger 93. Further, the temperature rising gas that has flowed into the second supply path 75B flows into the first supply path 57B at the connection portion 77B, and then flows into the gas side flow path 94b of the fourth heat exchanger 94. The temperature rising gases discharged from the third and fourth heat exchangers 93 and 94 to the discharge paths 64A and 64B merge at the connection portion 65 and flow into the gas side flow path 92b of the second heat exchanger 92. . Then, the temperature rising gas discharged from the second heat exchanger 92 flows into the air heater 101. That is, the temperature rising gas heats the flow path of the nitrogen gas that has been at a low temperature during the cooling operation, such as the second to fourth heat exchangers 92 to 94. The temperature rising gas whose temperature has been lowered by heating the nitrogen gas flow path is adjusted to a temperature equal to or higher than normal temperature by the air heater 101 and then introduced into the storage box 50.

  On the other hand, the dry air supplied from the dry air supply source 69 to the dry air supply path 90 is heated by the air heater 98 to a predetermined temperature higher than the second target temperature. Thereafter, the dry air circulates while heating the dry air supply path 90 and the first to third heat exchangers 91 to 93 that have cooled the dry air in stages during the cooling operation, and eventually flows into the medium flow path 58A.

  In this process, the temperature of the dry air gradually decreases, but the second and third heat exchangers 92 and 93 are also heated by the temperature rising gas from the second supply path 75A in addition to the dry air. Has been. Therefore, the dry air flowing into the medium flow path 58A flows into the medium flow path 58A at a higher temperature than when the temperature rising gas is not supplied to the second and third heat exchangers 92 and 93. The accommodation pocket 17A, which was at a low temperature during the cooling operation, is heated by the dry air flowing into the medium flow path 58A.

  The dry air discharged from the medium flow path 58A flows while heating the connection path 95 and the fourth heat exchanger 94 that has cooled the dry air during the cooling operation, and eventually flows into the medium flow path 58B. Even in this process, the temperature of the dry air gradually decreases, but the fourth heat exchanger 94 is also heated by the temperature rising gas from the second supply path 75B in addition to the dry air. Therefore, the dry air flowing into the medium flow path 58B flows into the medium flow path 58B at a higher temperature than when the temperature rising gas is not supplied to the fourth heat exchanger 94. The accommodation pocket 17B, which has been at a low temperature during the cooling operation, is heated by the dry air flowing into the medium flow path 58B.

  The dry air discharged from the medium flow path 58B to the dry air exhaust path 96 flows while heating the dry air exhaust path 96 and the first heat exchanger 91, and then flows into the air heater 100. The dry air is introduced into the storage box 50 after the temperature is adjusted to a temperature equal to or higher than the normal temperature by the air heater 100.

  As the temperature recovery operation proceeds, the temperature of the dry air supply path 90 and the first to fourth heat exchangers 91 to 94 rises, so that the temperature of the dry air flowing into the medium flow paths 58A and 58B is also a temperature equal to or higher than the normal temperature. To rise. When the detected values of the temperature sensors 63A and 63B eventually reach the second target temperature, the valve 78 is controlled to be closed, and the driving of the air heaters 79, 98, 100, and 101 is stopped, and the normal temperature recovery operation ends. Thereby, the temperature of the storage pockets 17A and 17B is switched from the first target temperature to the second target temperature, and accordingly, the temperature of the electronic component T stored in the storage pockets 17A and 17B is also changed from the first target temperature to the second target temperature. Switch to temperature. The valve 97 is controlled to be in an open state even after the normal temperature return operation is completed. As a result, dry air continues to be supplied into the storage box 50 and the storage box 50 is maintained in a dry state.

[Operation of Handler and Component Inspection Device in Second Embodiment]
Next, the operation of the handler and component inspection device in the second embodiment will be described. In the handler and the component inspection apparatus of the second embodiment, when the target temperature of the electronic component T is switched from the first target temperature to the second target temperature, the normal temperature recovery operation is performed.

  When the normal temperature recovery operation is started, the medium supplied to the first supply passages 57A and 57B is switched from nitrogen as the first medium to the temperature rising gas as the second medium, and from the dry air supply path 90 to the first supply gas. The dry air supplied to the 1 heat exchanger 91 is switched to dry air heated to a predetermined temperature higher than the second target temperature. Then, the flow path of dry air and the flow path of nitrogen gas are heated until the accommodation pockets 17A and 17B that have reached the first target temperature reach the second target temperature.

  For this reason, for example, when the respective storage pockets 17 </ b> A and 17 </ b> B are kept at a normal temperature, or when the temperature rising gas is not supplied to the second supply paths 75 </ b> A and 75 </ b> B and normal temperature dry air is supplied to the dry air supply path 90. Compared to the case, the temperature of the flow path of the dry air is raised early. As a result, since the temperature drop of the dry air in the process until reaching the medium flow paths 58A and 58B is suppressed, the time required for the storage pockets 17A and 17B to switch to the second target temperature can be shortened.

  The storage box 50 is supplied with dry air whose temperature is adjusted to normal temperature or higher by the air heater 100 and nitrogen gas or temperature rising gas whose temperature is adjusted to normal temperature or higher by the air heater 101. Therefore, compared with the case where the dry air discharged from the medium flow paths 58A and 58B, the nitrogen gas or the temperature rising gas discharged to the discharge paths 64A and 64B, and these are introduced into the storage box 50 at a temperature lower than normal temperature, It can suppress that the temperature in the storage box 50 falls to a temperature lower than the dew point at that time.

  In the dry air exhaust path 96, a check valve 99 is disposed downstream of the first heat exchanger 91. Therefore, during the period when the valve 97 is controlled to be closed, it is possible to suppress the air having a moisture content higher than that of the dry air from flowing into the dry air flow path from the storage box 50. As a result, it is possible to suppress the occurrence of dew condensation or icing in the dry air flow path during the cooling operation.

  As explained above, according to the handler and component inspection apparatus in the second embodiment, in addition to the effects equivalent to (2) to (5) and (7) to (11) described in the first embodiment, The following effects can be obtained.

  (12) The temperature of the dry air supplied to each of the accommodation pockets 17A and 17B can be effectively increased by heating the nitrogen gas flow path and the dry air flow path by the normal temperature recovery operation. As a result, the storage pockets 17A and 17B that are at the first target temperature can be switched to the second target temperature, and the time required to switch to the second target temperature can be shortened.

  (13) An air heater 101 that adjusts the nitrogen gas or the temperature rising gas discharged from the second heat exchanger 92 to a temperature equal to or higher than the normal temperature is disposed in the discharge path 64A. The dry air exhaust path 96 is provided with an air heater 100 that adjusts the dry air discharged from the medium flow path 58B to a temperature equal to or higher than room temperature. As a result, it is possible to suppress the temperature in the storage box 50 from dropping to a temperature lower than the dew point at that time, and it is possible to further suppress the occurrence of condensation in the storage box 50.

  (14) Since the check valve 99 is disposed on the downstream side of the first heat exchanger 91 in the dry air exhaust path 96, dew condensation and icing are formed in the dry air flow path upstream of the check valve 99. Can be prevented from occurring.

  In the first and second embodiments, the medium flow path may be formed in, for example, the supply shuttle plate 15a instead of the first shuttle 15, or may be connected to the first shuttle 15 and the supply shuttle plate 15a. It may be formed.

  -In the dry air supply path 90 of 2nd Embodiment, the structure by which the air heater 98 was omitted may be sufficient. Under such a configuration, as the normal temperature recovery operation proceeds, dry air heated by heat exchange with the temperature rising gas in the second to fourth heat exchangers 92 to 94 is supplied to the medium flow paths 58A and 58B. become.

In this case, the inspection socket 14 a is mounted on the handler 10 by being accommodated in the accommodating portion 122 of the pedestal 123. And the temperature of the electronic component accommodated in the test | inspection socket 14a is adjusted by adjusting the temperature of the base 123. FIG.

  Since the handler and the tester constituting the component inspection apparatus are separate units, when the test head 14 and the inspection socket 14a are used as a stage, a medium is previously placed on the test head 14 of the tester separately from the configuration on the handler side. It is necessary to provide a flowing medium flow path and a heater. In this regard, according to the above-described configuration, it is possible to adjust the temperature of the electronic component T accommodated in the inspection socket 14a without requiring the test head 14 including the medium flow path and the heater.

  The temperature sensor may be mounted on the pedestal 123 as long as the temperature of the inspection socket 14a can be detected, or may be mounted on the inspection socket 14a. Moreover, although one accommodating part 122 is formed in the base 123 of FIG. 14, the number of the accommodating parts 122 formed in the base 123 may be two or more. Further, the test head 14 and the inspection socket 14a may be accommodated in the accommodating portion 122 of the pedestal 123. The point is that the member itself that indirectly touches the electronic component with the heat conducting member interposed therebetween may be cooled as the supporting portion that supports the electronic component. When a plurality of accommodating portions 122 are formed on the pedestal 123, it is preferable that the pedestal 123 is formed with the medium flow paths 120 corresponding to the respective accommodating portions 122.

  In addition, the support part may be arbitrarily set as long as it is a part that supports the electronic component T on the mounting surface 11a of the base 11 or above the base 11 in the transport space covered by the cover member 12. Is possible. For example, the supply shuttle plate 15a and the recovery shuttle plate 15b may be provided as separate stages, and separate temperature adjustment units may be provided for these stages. In addition, a stage is disposed at the lower end suction portion of the first transfer unit 32 and the second transfer unit 33 in the transfer robot 30, and a temperature adjustment unit is provided at each lower end portion of the first transfer unit 32 and the second transfer unit 33. You may make it provide. In short, if it is a part where the electronic component T is supported, the temperature adjustment unit can be provided using that part as a support part. When the electronic component T is transported between the temperature adjustment units, the electronic component T may be transferred by opening and closing a part of the container.
