DETAILED DESCRIPTION
[0021] Hereinafter, the present invention will be described by way of the embodiments of the invention, but the following embodiments do not limit the invention of the claims. In addition, not all combinations of features described in the embodiments are necessarily essential to the solution means of the invention.
[0022] Figure 1 FIG. 1 is a schematic side view of a test device 50 provided with the plugging and unplugging device 100 according to the first embodiment. Figure 1 2 shows a state where a batch 20 of a plurality of test boards 10 is transferred to a test device 50 provided with an insertion and extraction device 100. The insertion and extraction device 100 and the test device 50 can communicate with each other in a wired or wireless manner.
[0023] exist Figure 1 The lower part shows the X-axis, Y-axis and Z-axis which are orthogonal to each other. Figure 1 When the paper is facing the right side, the right side is set as the positive side of the X-axis direction, and the left side is set as the negative side of the X-axis direction. Figure 1 When the paper is facing the Z axis, the inner side is set as the positive side of the Y axis and the front side is set as the negative side of the Y axis. Figure 1 When the paper is on the same plane, it extends in the up-down direction, and the upper side is set as the positive side in the Z-axis direction, and the lower side is set as the negative side in the Z-axis direction. The same is true in the subsequent figures, and repeated descriptions are omitted. In addition, in the subsequent description, the positive side in the Z-axis direction is sometimes referred to as the upper side, and the negative side in the Z-axis direction is sometimes referred to as the lower side.
[0024] As an example, the test board 10 has a plurality of pocket-shaped areas formed in a matrix on the upper surface, and a device under test (DUT) is contained in each pocket-shaped area. In other words, a plurality of devices under test are arranged in sequence on the test board 10. The test board 10 has an electrical connection portion 11 electrically connected to the plurality of devices under test that have been arranged. The electrical connection portion 11 is formed at one end of the test board 10.
[0025] like Figure 1 As shown in FIG. 1 , a batch material 20 of a plurality of test plates 10 is held by a holder 30 in a state where the plurality of test plates 10 are arranged in one direction. The batch material 20 held by the holder 30 is as shown in FIG. Figure 1 The batch material 20 is transferred from the electrical connection portion 11 side of each test plate 10 to the test device 50 as indicated by the transfer direction indicated by the hollow arrow toward the negative side of the X-axis direction. The batch material 20 can be transferred into the test device 50 by, for example, the user pushing a trolley carrying the batch material 20 held by the holder 30 into the test device 50.
[0026] In this embodiment, the test device 50 includes a chamber 51 and a connector unit 52. The chamber 51 accommodates a plurality of test boards 10. Figure 1 In FIG. 5 , the chamber 51 is indicated by a dotted line. The connector unit 52 includes a plurality of electrical connectors 53 that are electrically connected to the plurality of test boards 10 housed in the chamber 51. Figure 1 In the figure, a part of the connector unit 52 that cannot be visually confirmed by the plugging and unplugging device 100 is indicated by a dotted line. In addition, in the following figures, a part that cannot be visually confirmed is sometimes indicated by a dotted line, and repeated description is omitted.
[0027] The test device 50 inserts the electrical connection parts 11 of the plurality of test boards 10 arranged in one direction in the chamber 51 into the electrical connectors 53 of the connector unit 52, or removes them from the electrical connectors 53, by means of the plug-in and pull-out device 100. In the following description, the action of inserting the electrical connection parts 11 of the test boards 10 into the electrical connectors 53 of the test device 50 is sometimes referred to as an insertion action, the action of removing the electrical connection parts 11 of the test boards 10 from the electrical connectors 53 of the test device 50 is sometimes referred to as a pull-out action, and the insertion action and the pull-out action are sometimes collectively referred to as a plug-in and pull-out action.
[0028] The test device 50 accommodates a plurality of test boards 10 in a chamber 51, and performs a functional test on the devices under test by energizing the devices under test on each test board 10 electrically connected to the connector unit 52. As an example, the test device 50 may be an aging test device that performs temperature control to bring the chamber 51 accommodating the plurality of test boards 10 close to a target temperature, and performs a functional test on the devices under test on each test board 10.
[0029] For example, the test device 50 instructs the plugging device 100 to start the insertion operation in response to the batch material 20 held by the holder 30 being transferred to a predetermined position in the chamber 51 of the test device 50. The predetermined position is a position where the plugging device 100 disposed in the chamber 51 can insert the electrical connection portions 11 of each of the plurality of test boards 10 arranged in one direction into each of the electrical connectors 53 of the test device 50. This position is, for example, Figure 1 The configuration shown on the left has multiple test board 10 locations.
[0030] As a more specific example, the test device 50 may also have a sensor for detecting that the batch material 20 is placed at the position, such as an infrared sensor or a load sensor, and may also instruct the plugging and unplugging device 100 to start the insertion action in response to detecting that the batch material 20 is placed at the position. Alternatively, the plugging and unplugging device 100 may also be equipped with the sensor, in which case the plugging and unplugging device 100 may start the insertion action in response to detecting that the batch material 20 is placed at the position.
[0031] The plugging and unplugging device 100 is a device for inserting each electrical connection portion 11 of each test board 10 into each electrical connector 53 of the test device 50 and unplugging each electrical connector 53 when a plurality of test boards 10 are arranged in one direction. As an example, the plugging and unplugging device 100 of this embodiment performs these two actions.
[0032] The plugging and unplugging device 100 includes a load unit 110 and an plugging and unplugging driving unit 150. The load unit 110 applies a load to each test board 10. The load unit 110 applies a load in the direction in which the insertion operation of each test board 10 is performed, that is, in the X-axis direction.
[0033] Figure 2 yes Figure 1 Schematic front view of the plugging and unplugging device 100 with the batch material 20 transferred is shown on the left side of FIG. Figure 3 yes Figure 1 The schematic top view of the plugging and unplugging device 100 with the batch material 20 transferred is shown on the left side of FIG. Figure 2 and Figure 3As shown, the load portion 110 may be, for example, one or more claws or hooks. The load portion 110 is positioned in a manner that does not contact the holder 30, which holds the batch 20 of the plurality of test boards 10. In addition, in the following description, the direction in which the plurality of test boards 10 are arranged may be referred to as the Z-axis direction, and the direction in which the plugging and unplugging action is performed may be referred to as the X-axis direction.
[0034] The plug-in drive unit 150 causes the load unit 110 to meander in one direction, thereby the load unit 110 sequentially applies loads to the plurality of test boards 10. As a more specific example, the plug-in drive unit 150 causes the load unit 110 to meander in the Z-axis direction, thereby the load unit 110 sequentially applies loads to the plurality of test boards 10 arranged in the Z-axis direction while being stuck on a part of each test board 10 in sequence and sliding up and down.
[0035] For example, the plug-in drive unit 150 starts or stops the load unit 110 from moving in a meandering manner along the Z-axis direction according to the control signal from the test device 50. More specifically, the plug-in drive unit 150 moves the load unit 110 in a meandering manner along the Z-axis direction according to the control signal from the test device 50, so that the load unit 110 applies loads to the plurality of test boards 10 in sequence.
[0036] Alternatively, the plug-in drive unit 150 may also start or stop the load unit 110 from moving in a meandering manner along the Z-axis direction through an open control of the controller of the plug-in device 100. More specifically, the controller of the plug-in device 100 may also create a schedule, and control the actions of the plug-in drive unit 150 on the load unit 110 according to the schedule, wherein the schedule indicates starting or stopping the load unit 110 from moving in a meandering manner along the Z-axis direction and the test device 50 performing a functional test on the device under test. In this case, the controller of the plug-in device 100 may further send the schedule to the test device 50 and control the functional test of the device under test in the test device 50.
[0037] Alternatively, the plug-in drive unit 150 may also start or stop the load-bearing unit 110 from moving in a meandering manner along the Z-axis direction through feedback control of the controller of the plug-in device 100. More specifically, the controller of the plug-in device 100 may also instruct the plug-in drive unit 150 to start or stop the load-bearing unit 110 from moving in a meandering manner along the Z-axis direction, and send a feedback signal indicating that the meandering movement of the load-bearing unit 110 in one direction has ended or stopped from the plug-in drive unit 150 to the controller. In this case, the controller of the plug-in device 100 may further cause the test device 50 to start a functional test of the device under test, and send a feedback signal indicating that the functional test has ended to the controller. The controller of the plug-in device 100 may also instruct the plug-in drive unit 150 to start moving the load-bearing unit 110 in a meandering manner along the Z-axis direction in response to receiving the feedback signal from the test device 50.
[0038] Figure 4 1 is a schematic perspective view of the plugging and unplugging device 100 according to the first embodiment. Figure 4 As shown in FIG. 1 , the plug-in drive unit 150 includes a rotating shaft 151, a first component 152, a fixed channel 153, a second component 156, and a motor 159. Figure 4 As shown, the load portion 110 includes: a first load portion 120 for inserting each electrical connection portion 11 into each electrical connector 53; and a second load portion 130 for pulling each electrical connection portion 11 out of each electrical connector 53. Figure 4 In order to explain the configuration of each component of the plug-in device 100, a part of the second component 156 is shown in a perspective manner. In the subsequent figures, arbitrary components may also be shown in a perspective manner or represented by dotted lines, and repeated descriptions are omitted.
[0039] The rotating shaft 151 rotates around an axis extending in one direction. More specifically, the rotating shaft 151 is driven to rotate in a clockwise direction and a counterclockwise direction around an axis extending in the Z-axis direction by a motor 159 installed at one end in the Z-axis direction. As an example, the rotating shaft 151 has a spiral thread (not shown) formed on the cylindrical surface. Figure 4 In the figure, the rotation direction of the rotating shaft 151 is indicated by an arrow, and the same is true in the subsequent figures, and repeated description is omitted.
[0040] If by reference Figures 1 to 4 As understood, the plugging and unplugging drive unit 150 of the plugging and unplugging device 100 of this embodiment has two rotating shafts 151 spaced apart from each other in the Y-axis direction, and a plurality of batches 20 of test boards 10 are arranged between the two rotating shafts 151. The plugging and unplugging drive unit 150 synchronizes the rotational drive of the two rotating shafts 151 by the motor 159.
[0041] The first member 152 is engaged to be rotatable around the rotation shaft 151 , and moves in one direction as the rotation shaft 151 rotates. Figure 5 yes Figure 4 The enlarged view of the local area 1. Figure 5 As shown, more specifically, as an example, the first member 152 is one or more plate-shaped members having a hole, and the hole has a thread formed on the inner surface, and the thread has a shape complementary to the spiral thread of the rotating shaft 151.
[0042] As an example, the first component 152 is as follows Figure 4As shown by the solid arrow in , when the rotating shaft 151 is driven to rotate in the clockwise direction by the motor 159, it translates toward the positive side in the Z-axis direction, and when the rotating shaft 151 is driven to rotate in the counterclockwise direction by the motor 159, it translates toward the negative side in the Z-axis direction. In addition, the combination of the rotation direction of the rotating shaft 151 and the translation direction of the first component 152 may be opposite to this example. In addition, the first component 152 may be referred to as a feed screw, and the combination of the first component 152, the rotating shaft 151, and the motor 159 may be referred to as a feed screw mechanism.
[0043] like Figure 4 As shown, the plugging and unplugging drive unit 150 of the plugging and unplugging device 100 of this embodiment has first components 152 for two rotating shafts 151 spaced apart from each other in the Y-axis direction. As the motor 159 synchronously drives the two rotating shafts 151 to rotate, the two first components 152 are translated synchronously along the Z-axis direction.
[0044] The fixing channel 153 includes a wavy track extending in a winding direction. Figure 6 yes Figure 4 An enlarged view of the local area 2. Figure 7 This is a schematic plan view showing a part of the plugging and unplugging device 100 according to the first embodiment in an enlarged manner. Figure 8 yes Figure 7 Schematic front view of the shown part. Fig. 9 yes Figure 7 Schematic side view of the portion shown. Figures 6 to 9 As shown, more specifically, on the second member 156 side of the fixed channel 153, as an example, a cam groove 154 of a wave-shaped track extending in a meandering manner in the Z-axis direction is formed. Figures 7 to 9 In the figure, a part of the structure is omitted by using wavy lines, and the same is true in the subsequent figures, and repeated explanations are omitted.
[0045] like Figures 5 to 8 As shown, the fixed channel 153 further includes a linear guide 155 extending in the Z-axis direction, and a slider of the linear guide 155 is fixed to the first component 152. The fixed channel 153 can limit the rotational movement of the first component 152 in the Z-axis direction through the linear guide 155, while achieving its translation in the Z-axis direction, and the first component 152 is engaged in a manner that allows rotation around the rotation axis 151.
[0046] Fig.10 yes Figure 4 An enlarged view of the local area 3. Fig.11 FIG. 1 is a schematic top view showing a part of the plugging and unplugging device 100 of the first embodiment in an enlarged manner. Figure 4 , Fig.10 and Fig.11As shown, the fixed channel 153 further includes a pair of linear guides 155 spaced apart from each other in the X-axis direction, through which the second component 156 and the load portion 110 are held and the translation of the second component 156 and the load portion 110 in the Z-axis direction is stabilized.
[0047] like Figure 4 As shown, similarly to the pair of rotating shafts 151, the plug-in drive unit 150 of the plug-in device 100 of the present embodiment has a pair of fixed channels 153 that are separated from each other in the Y-axis direction. The configuration of the pair of rotating shafts 151 and the pair of fixed channels 153 in the plug-in drive unit 150, and the configuration of the second component 156 and the load unit 110 attached to these components can be plane-symmetrical with each other with the batch 20 of multiple test plates 10 interposed in the middle as the center. In the subsequent description of the plug-in drive unit 150 and the load unit 110, sometimes only one of the group of the plug-in drive unit 150 and the load unit 110 located on the positive side of the Y-axis direction of the batch 20 and the group of the plug-in drive unit 150 and the load unit 110 located on the negative side of the Y-axis direction of the batch 20 is described, and the description of the other is omitted.
[0048] The second component 156 is engaged with the first component 152 in a manner that allows it to slide in the direction of the insertion and removal action. The second component 156 can move along the track of the fixed channel 153 while maintaining the load portion 110. Specifically, Figures 5 to 11 As shown, the second member 156 is formed with a cam follower 157 that slides in the cam groove 154 of the fixed channel 153, and the second member 156 can move along the wavy track of the cam groove 154 that extends in the Z-axis direction. The second member 156 moves along the track to move the held load portion 110 integrally.
[0049] More specifically, if Figures 5 to 11 As shown in FIG. 1 , as an example, the second component 156 includes a linear guide 158 extending in the X-axis direction, and is engaged with the first component 152 in a manner that it can slide in the X-axis direction through the linear guide 158. More specifically, one end of the linear guide 158 of the second component 156 on the positive side in the X-axis direction of the guide rail extending in the X-axis direction is fixed to the slider of the linear guide 155 located on the positive side in the X-axis direction among the pair of linear guides 155 of the fixed channel 153. In addition, one end of the linear guide 158 of the second component 156 on the negative side in the X-axis direction of the guide rail extending in the X-axis direction is fixed to the first component 152. In addition, one end of the linear guide 158 of the second component 156 on the negative side in the X-axis direction of the slider extending in the X-axis direction is formed with a cam follower 157 on the fixed channel 153 side. The outer diameter of the cam follower 157 of the second member 156 may be the same as the width of the cam groove 154 , or slightly smaller than the width of the cam groove 154 .
[0050] like Figure 4 As shown by the solid arrow in , as the first component 152 translates in the Z-axis direction, the cam follower 157 slides in the cam groove 154, whereby the second component 156 translates in the Z-axis direction together with the first component 152, and simultaneously moves back and forth in the X-axis direction independently of the first component 152. The movement amount of the second component 156 in the X-axis direction corresponds to the X-axis width of the cam groove 154 of the fixed channel 153. Therefore, as the first component 152 translates in the Z-axis direction, the first load portion 120 and the second load portion 130 held by the second component 156 move along the same track as the track of the cam groove 154 of the fixed channel 153, that is, they move in a meandering manner in the Z-axis direction.
[0051] The motor 159 drives the rotating shaft 151 to rotate in the clockwise direction and the counterclockwise direction according to the control signal from the test device 50. Figure 4 As shown in FIG. 1 , the plugging and unplugging drive unit 150 of the plugging and unplugging device 100 of this embodiment has motors 159 for each of the pair of rotating shafts 151. As described above, the rotational drives of the pair of motors 159 are synchronized with each other. Figure 7 and Fig. 9 The illustration of motor 159 is omitted in the figure, and it may also be omitted in subsequent figures, and repeated descriptions are omitted.
[0052] As a specific example, Figure 3 and Figure 4 As shown, the first load part 120 and the second load part 130 are a pair of hooks arranged separately from each other in the X-axis direction. The load part 110 in this embodiment includes two groups of pairs of the first load part 120 and the second load part 130, one of which is on the positive side of the test board 10 in the Y-axis direction, and the first load part 120 and the second load part 130 are respectively located near the test board 10, and the other group is on the negative side of the test board 10 in the Y-axis direction, and the first load part 120 and the second load part 130 are respectively located near the test board 10.
[0053] As described above, the first load portion 120 and the second load portion 130 are held by the second component 156 of the plug-in drive unit 150, and move in the Z-axis direction and the X-axis direction integrally with the slider of the second component 156, that is, move in a meandering manner in the Z-axis direction. The first load portion 120 and the second load portion 130 may be different from the second component 156 but joined to each other, or may be formed integrally with the second component 156.
[0054] like Fig.11As shown, the first load part 120 applies a load to the first end 13 of each test board 10 on the opposite side of each electrical connector 53 in the X-axis direction. Thus, the first load part 120 inserts each electrical connection part 11 of each test board 10 into each electrical connector 53.
[0055] As an example, Fig.11 As shown, the first load part 120 includes a rotating mechanism 121, and the rotating mechanism 121 is used to reduce the friction with the surface of each test plate 10 to which the load is applied. As an example, the rotating mechanism 121 may include a rotating member 123 that rotates around an axis orthogonal to the surface of each test plate 10 to which the load is applied, in which case the rotating member 123 is in surface contact with the surface of each test plate 10 to which the load is applied. The rotating member 123 is, for example, a bearing, and can rotate in the ZY plane around a rotating axis that is fixed to the first load part 120 and extends in the X-axis direction.
[0056] When the first load unit 120 applies a load to the first end portion 13 of the test plate 10, the rotating member 123 receives the first end portion 13 of the test plate 10 on the half of the rotating surface of the rotating member 123 located on the negative side in the Y-axis direction. More specifically, the rotating member 123 applies a load to the first end portion 13 of the test plate 10 while rotating around the axis due to the friction force received from the first end portion 13 of the test plate 10. In other words, the rotating member 123 slides up and down on the first end portion 13 of the test plate 10 while applying a load to the first end portion 13 of the test plate 10.
[0057] like Figures 7 to 9 As shown, the second load part 130 applies a load to the second end 15 of each test board 10 on the electric connector 53 side in the X-axis direction. Thus, the second load part 130 pulls out each electric connection part 11 of each test board 10 from each electric connector 53.
[0058] As an example, similarly to the first load-bearing portion 120, Figure 8 and Fig. 9 As shown, the second load part 130 includes a rotating mechanism 131, and the rotating mechanism 131 is used to reduce the friction with the surface of each test plate 10 to which the load is applied. As an example, the rotating mechanism 131 may include a rotating member 133 that rotates around an axis orthogonal to the surface of each test plate 10 to which the load is applied, in which case the rotating member 133 is in surface contact with the surface of each test plate 10 to which the load is applied. Similar to the rotating member 123, the rotating member 133 is, for example, a bearing, and can rotate in the ZY plane around a rotating axis that is fixed to the second load part 130 and extends in the X-axis direction.
[0059] When the second load unit 130 applies a load to the second end portion 15 of the test plate 10, the rotating member 133 receives the second end portion 15 of the test plate 10 on the half of the rotating surface of the rotating member 133 located on the negative side in the Y-axis direction. More specifically, the rotating member 133 applies a load to the second end portion 15 of the test plate 10 while rotating around the axis due to the friction force received from the second end portion 15 of the test plate 10. In other words, the rotating member 133 applies a load to the second end portion 15 of the test plate 10 while sliding up and down on the second end portion 15 of the test plate 10.
[0060] Fig.12 This is a flowchart for explaining an example of the operation flow of the plugging and unplugging method according to the first embodiment. Fig.12 In the action flow, with a plurality of test boards 10 arranged in the Z-axis direction, two actions are performed: inserting each electrical connection portion 11 of each test board 10 into each electrical connector 53 of the test device 50 and removing each electrical connector 53.
[0061] As an example, the following action flow starts by placing the load part 110 at the initial position by the plug-in device 100. The plug-in device 100 can place the load part 110 at the initial position at any time point within the following period, which is from the end of the functional test of the last batch of materials 20 by the test device 50 to the start of the first step in the following action flow.
[0062] Here, the initial position of the load portion 110 refers to a position in the Z-axis direction where the load portion 110 does not contact the batch material 20 of the plurality of test plates 10 held by the holder 30 when the batch material 20 is transferred into or taken out of the chamber 51 of the test device 50. More specifically, the initial position of the load portion 110 refers to a position in the Z-axis direction where the load portion 110, which can be moved from the negative side of the Z-axis direction to the positive side of the Z-axis direction by the plug-in drive unit 150, does not contact the batch material 20 or the holder 30.
[0063] For example, when the load section 110 is moved in a meandering manner toward the positive side in the Z-axis direction so that the plurality of test boards 10 are sequentially connected to the electrical connector 53 of the test device 50, any position on the negative side in the Z-axis direction of the test board 10 located in the lowermost section among the plurality of test boards 10 arranged along the Z-axis direction is the initial position in the Z-axis direction of the load section 110. For example, when the load section 110 is moved in a meandering manner toward the negative side in the Z-axis direction so that the plurality of test boards 10 are sequentially connected to the electrical connector 53 of the test device 50, any position on the positive side in the Z-axis direction of the test board 10 located in the uppermost section among the plurality of test boards 10 arranged along the Z-axis direction is the initial position in the Z-axis direction of the load section 110.
[0064] In response to the batch material 20 having been transferred to the above-mentioned predetermined position in the chamber 51 of the testing device 50, the plug-in device 100 causes the load-bearing portion 110 to meander from the initial position toward one side in the Z-axis direction, thereby sequentially inserting each electrical connection portion 11 into each electrical connector 53 of the testing device 50 for multiple test boards 10 of the batch material 20 (step S101).
[0065] Regarding step S101, specifically, in response to detecting that the batch material 20 is placed at the above-mentioned position, the test device 50 sends a control signal indicating the start of the insertion action to the plug-in device 100. The plug-in drive unit 150 of the plug-in device 100 causes the load unit 110 to meander from the initial position toward the positive side in the Z-axis direction according to the control signal from the test device 50, thereby the load unit 110 sequentially applies loads to the multiple test boards 10. More specifically, the plug-in drive unit 150 causes the load unit 110 to meander toward the positive side in the Z-axis direction, thereby the load unit 110 sequentially applies loads to the ends of the multiple test boards 10 in the X-axis direction. After the plug-in drive unit 150 causes the load unit 110 to meander from the initial position located at the negative side end in the Z-axis direction to the standby position located at the positive side end in the Z-axis direction, the load unit 110 stands by at the standby position.
[0066] In response to the electrical connection of the electrical connection portions 11 of the multiple test boards 10 to the electrical connectors 53, the test device 50 performs temperature control to bring the temperature in the chamber 51 accommodating the multiple test boards 10 close to the target temperature, and performs functional testing of the tested devices on each test board 10 (step S103).
[0067] In response to the completion of the above-mentioned functional test performed by the test device 50, the plug-in device 100 causes the load-bearing portion 110 to meander from the standby position toward the other side of the Z-axis direction, thereby sequentially unplugging each electrical connection portion 11 from each electrical connector 53 of the test device 50 for multiple test boards 10 (step S105), and the process ends.
[0068] Regarding step S105, specifically, in response to the completion of the above-mentioned functional test, the test device 50 sends a control signal indicating the start of the unplugging action to the plugging device 100. The plugging drive unit 150 of the plugging device 100 causes the load unit 110 to meander from the standby position toward the negative side in the Z-axis direction according to the control signal from the test device 50, thereby the load unit 110 sequentially applies loads to the multiple test boards 10. More specifically, the plugging drive unit 150 causes the load unit 110 to meander from the standby position toward the negative side in the Z-axis direction, thereby the load unit 110 sequentially applies loads to the ends of the multiple test boards 10 in the X-axis direction. After the plugging drive unit 150 causes the load unit 110 to meander from the standby position to the initial position, the load unit 110 is placed on standby at the initial position.
[0069] In addition, the plug-in and unplug device 100 can notify the user through sound or light, etc. that the unplugging of all test boards 10 has been completed, and the user can transfer the batch material 20 held by the retaining frame 30 in the chamber 51 of the test device 50 to the trolley and move the batch material 20 out of the chamber 51.
[0070] Fig.13 1 is a schematic side view for explaining the plugging and unplugging operation of the plugging and unplugging device 100 according to the first embodiment. Fig.13 10 test boards 10 are shown arranged along the Z-axis direction. Among the 10 test boards 10, 4 test boards 10 on the positive side of the Z-axis direction are being inserted by the plug-in device 100, and 6 test boards 10 on the negative side of the Z-axis direction are being removed by the plug-in device 100. Fig.13 The thick solid line schematically shows a wave-shaped track along which the first load portion 120 and the second load portion 130 can move and extend in a meandering manner in the Z-axis direction. Fig.13 In the figure, arrows are shown at both ends of the two tracks, but this is only to make the description clearer. Fig.13 The same, repeated description is omitted.
[0071] As an example, the plug-in drive unit 150 moves the first component 152 toward the positive side in the Z-axis direction by rotating the rotating shaft 151 in one direction around the axis, for example, in the clockwise direction. Thus, the plug-in drive unit 150 causes the second component 156, which is engaged relative to the first component 152 in a manner that allows it to slide in the X-axis direction, to slide in the cam groove 154 of the fixed channel 153 via the cam follower 157 of the second component 156, and to move along the wavy track of the cam groove 154 that extends in a winding manner in the Z-axis direction. Thus, the plug-in drive unit 150 causes the first load portion 120 and the second load portion 130 held by the second component 156 to move in a winding manner toward the positive side in the Z-axis direction, so that the first load portion 120 sequentially applies a load to the first end portion 13 in the X-axis direction of each of the plurality of test plates 10. Thus, for example, as indicated by the hollow arrow, Fig.13 The four test boards 10 on the positive side in the Z-axis direction are moved toward the negative side in the X-axis direction, and the electrical connection parts 11 are inserted into the corresponding electrical connectors 53 in the test device 50. During the period when the plug-in drive unit 150 causes the first load part 120 and the second load part 130 to meander toward the positive side in the Z-axis direction, that is, during the insertion operation, the second load part 130 may not contact the test boards 10, or may apply a load to the second end 15 of each test board 10 to slightly move each test board 10 toward the positive side in the X-axis direction.
[0072] As an example, the plug-in drive unit 150 moves the first component 152 toward the negative side in the Z-axis direction by rotating the rotating shaft 151 in another direction around the axis, for example, counterclockwise. Thus, the plug-in drive unit 150 causes the second component 156, which is engaged relative to the first component 152 in a manner that allows it to slide in the X-axis direction, to move along the wavy track of the cam groove 154 that extends in a winding manner in the Z-axis direction by sliding the cam follower 157 of the second component 156 in the cam groove 154 of the fixed channel 153. Thus, the plug-in drive unit 150 causes the first load portion 120 and the second load portion 130 held by the second component 156 to move in a winding manner toward the negative side in the Z-axis direction, and thus the second load portion 130 sequentially applies a load to the second end portions 15 in the X-axis direction of each of the plurality of test plates 10. Thus, for example, as indicated by the hollow arrow, Fig.13 The six test boards 10 on the negative side in the Z-axis direction are moved toward the positive side in the X-axis direction, and the electrical connection parts 11 are pulled out from the corresponding electrical connectors 53 in the test device 50. During the period when the plug-in drive unit 150 causes the first load part 120 and the second load part 130 to meander toward the negative side in the Z-axis direction, that is, during the pulling-out operation, the first load part 120 does not contact the test boards 10.
[0073] Fig.14 1 is a schematic side view for explaining the arrangement and configuration of the load portion 110 of the plugging and unplugging device 100 according to the first embodiment using a comparative example. Fig.14 A portion of the plugging and unplugging device 100 according to the first embodiment is shown on the upper side of Fig.14 The lower side of the figure shows a plug-in device of a comparative example. Fig.14 1 and 2 respectively show the initial position and insertion position of a test board 10 in the X-axis direction during the insertion operation by each plugging and unplugging device. Fig.14 In the figure, the first load part 120 and the second load part 130 are shown in multiple positions that can be taken in the plugging and unplugging operation by dashed boxes on each track. The same is true in the subsequent figures, and repeated description is omitted.
[0074] like Fig.14 As shown on the lower side of , according to the plugging and unplugging device of the comparative example, the positions of the first load part 120 and the second load part 130 in the Z-axis direction are substantially the same. Therefore, depending on the relationship between the size of the test board 10 and the configuration of the first load part 120 and the second load part 130, for example, there may be a situation where, when the first load part 120 is to apply a load to the first end 13 of the test board 10 to move the test board 10 to the negative side in the X-axis direction, the second load part 130 contacts the lower surface of the test board 10, and thus the insertion action cannot be accurately performed.
[0075] In contrast, Fig.14As shown on the upper side, according to the plug-in device 100 of the first embodiment, the first load portion 120 and the second load portion 130 are offset from each other in the Z-axis direction and the relative positions are fixed in the following manner, that is, during the period when one of the first load portion 120 and the second load portion 130 applies a load to the end of a test plate 10, the other of the first load portion 120 and the second load portion 130 does not contact the end surface of the test plate 10 in the Z-axis direction. More specifically, the first load portion 120 is located on the lower end side of the second component 156 in the Z-axis direction, and the second load portion 130 is located on the upper end side of the second component 156 in the Z-axis direction, and the positions of the first load portion 120 and the second load portion 130 in the Z-axis direction are offset from each other by about the width of the second component 156 in the Z-axis direction. Therefore, the plug-in device 100 of the present embodiment is different from the plug-in device of the comparative example, as shown in FIG. Fig.14 As shown in the upper side of the test plate 10, while the first load part 120 applies a load to the first end 13 of the test plate 10, the second load part 130 does not contact the lower surface of the test plate 10. Similarly, while the second load part 130 applies a load to the second end 15 of the test plate 10, the first load part 120 does not contact the upper surface of the test plate 10.
[0076] Fig.15 and Fig.16 This is a schematic side view for explaining in detail the insertion operation of the plugging and unplugging device 100 according to the first embodiment. Fig.15 and Fig.16 In FIG. 1 , the time periods T1 to T9 during the insertion operation of a test board 10 by the plugging and unplugging device 100 are shown on the respective tracks of the first load portion 120 and the second load portion 130. Among the states of the plugging and unplugging device 100 at each of the time periods T1 to T9, the states at the time periods T1 and T2 are shown in FIG. Fig.15 The states from time T5 to time T8 are shown in Fig.16 In addition, Fig.15 and Fig.16 1 shows any one of the initial position, the tentative position, and the inserted position in the X-axis direction of one test board 10 that is inserted by the insertion and extraction device 100 .
[0077] As described above, the first load part 120 and the second load part 130 meander toward the positive side in the Z-axis direction as a whole during the insertion operation, and therefore, the wave-shaped tracks of the first load part 120 and the second load part 130 have the same period and amplitude. However, the second load part 130 is located at a position closer to the positive side in the Z-axis direction than the first load part 120, and therefore, there is a phase difference between the wave-shaped tracks of the first load part 120 and the second load part 130, and the positions of the two in the Z-axis direction are different at the same time.
[0078] like Fig.15As shown, at time T1, the test board 10 is located at the initial position in the X-axis direction. More specifically, when the batch material 20 is placed in the above-mentioned predetermined position in the chamber 51 of the test device 50, each test board 10 of the batch material 20 is located at the initial position, and the electrical connection portion 11 of each test board 10 is in a state of facing the positive side of the corresponding electrical connector 53 in the test device 50 in the X-axis direction. At time T1, neither the first load portion 120 nor the second load portion 130 of the plug-in device 100 applies a load to the test board 10 shown in the figure.
[0079] The second load part 130 located on the positive side in the Z-axis direction than the first load part 120 applies a load to the second end 15 of the test plate 10 during the process from time T1 to time T2, so that the test plate 10 is slightly moved to the positive side in the X-axis direction as indicated by the solid arrow. Therefore, at time T2, the test plate 10 is located at a temporary position in the X-axis direction. When the test plate 10 is located at the temporary position in the X-axis direction, the first end 13 of the test plate 10 is located on the positive side in the X-axis direction than the center position in the X-axis direction of the wavy track extending along the Z-axis direction of the first load part 120, and on the negative side in the X-axis direction than the maximum position in the X-axis direction of the track.
[0080] After the time T2 , the second load portion 130 moves to the positive side in the Z-axis direction relative to the test plate 10 shown in the figure, and therefore does not come into contact with the test plate 10 .
[0081] During the process from time T2 to time T5, the first load unit 120 still does not apply a load to the test plate 10 shown in the figure. Fig.16 As shown, during the process from time T6 to time T8, the first load unit 120 applies a load to the first end portion 13 of the test board 10, and as shown by the solid arrow, the test board 10 moves toward the negative side in the X-axis direction. Therefore, at time T8, the test board 10 is located at the insertion position in the X-axis direction, and the electrical connection portion 11 of the test board 10 is in a state of being inserted into the corresponding electrical connector 53 in the test device 50.
[0082] According to the plug-in device 100 of the first embodiment described above, the plug-in drive unit 150 causes the load unit 110 to meander along the Z-axis direction, thereby the load unit 110 sequentially applies loads to the multiple test boards 10 arranged along the Z-axis direction. In this way, the plug-in device 100 does not apply loads to all the multiple test boards 10 at once, but applies loads to the multiple test boards 10 one by one in sequence, thereby reducing the force required for the insertion or removal of the multiple test boards 10 compared to the case where the loads are applied together. Therefore, the plug-in device 100 does not require a high-torque motor required to apply loads to the multiple test boards 10 at once, thereby suppressing the manufacturing cost and operating power of the plug-in device 100. In addition, according to the plug-in device 100, in order to increase the number of test boards 10 for a functional test of the test device 50 at one time, it is only necessary to lengthen the Z-axis direction length of the cam groove 154 of the fixing channel 153, so the expandability is also excellent.
[0083] Furthermore, according to the plugging and unplugging device 100, as a mechanism for sequentially applying loads to the plurality of test boards 10, a feed screw mechanism and a combination of a cam groove 154 having a wavy track and a cam follower 157 are used, instead of a cylinder that applies loads to the test board 10 while ascending and descending in the Z-axis direction and extending and retracting in the X-axis direction. Thus, the plugging and unplugging device 100 can also be applied to an aging test device in which the temperature in the chamber 51 is high.
[0084] Fig.17 1 is a schematic top view of a plugging and unplugging device 200 according to the second embodiment to which a plurality of test boards 60 are transferred. As a difference from the plugging and unplugging device 100 according to the first embodiment, the plugging and unplugging device 200 according to the second embodiment does not include the first load portion 120 and the second load portion 130. More specifically, the test board 60 to be plugged and unplugged has notches 63 on both side surfaces extending in the X-axis direction, and accordingly, the plugging and unplugging device 200 according to the second embodiment includes a load portion 210 for applying a load to the inner surface of the notch 63. In addition, the plugging and unplugging device 200 according to the second embodiment does not include the first load portion 120 and the second load portion 130 which are arranged to be spaced apart from each other in the X-axis direction, but includes the load portion 210 instead, and accordingly, includes a plugging and unplugging drive unit 250 in which the second component for holding the load portion 210 is shortened in the X-axis direction and the linear guide 158 is omitted. The other structures of the plugging device 200 of the second embodiment are the same as the corresponding structures of the plugging device 100 of the first embodiment, and the same reference numerals as the corresponding structures of the plugging device 100 of the first embodiment are used, and repeated description is omitted. The same is true for the description of the subsequent multiple embodiments, and repeated description is omitted.
[0085] Fig.18 yes Fig.17 The enlarged view of the local area 4. Fig.18As shown, a notch 63 is formed on a side surface of the test plate 60 extending in the X-axis direction. The notch 63 includes a first inner surface 65 and a second inner surface 66 facing each other in the X-axis direction.
[0086] According to the plugging and unplugging device 200 of the second embodiment, the plugging and unplugging driving unit 250 causes the load unit 210 to meander in the Z-axis direction, thereby causing the load unit 210 to sequentially apply loads to the inner surfaces of the notches 63 of the plurality of test boards 60. More specifically, the load unit 110 applies a load to a first inner surface 65 on the electric connector 53 side of the notch 63 in the X-axis direction, thereby inserting the electric connection portions 61 of the test boards 60 into the electric connectors 53 of the test device 50. Similarly, the load unit 110 applies a load to a second inner surface 66 on the opposite side of the electric connector 53 side of the notch 63 in the X-axis direction, thereby removing the electric connection portions 61 of the test boards 60 from the electric connectors 53 of the test device 50.
[0087] like Fig.18 As shown, the load portion 210 may include a rotating mechanism 211 , and specifically, may include a rotating member 213 on at least one of a first surface side facing the first inner surface 65 of the notch 63 and another surface side facing the second inner surface 66 of the notch 63 .
[0088] According to the plugging and unplugging device 200 of the second embodiment described above, the same effects as those of the plugging and unplugging device 100 of the first embodiment can be achieved.
[0089] Fig.19 : is a schematic stereoscopic diagram of a plug-in device 300 of the third embodiment. As a difference from the plug-in device 100 of the first embodiment, the load portion 110 of the plug-in device 300 of the third embodiment includes a load portion pair that can move in opposite directions to each other in the Z-axis direction. In addition, in order to make the load portions 110 of the load portion pair move in opposite directions to each other in the Z-axis direction, the plug-in device 300 of the third embodiment includes a plug-in drive unit 350 having a rotating shaft 351, and the rotating shaft 351 is formed with a spiral thread in opposite directions from the center of the Z-axis direction. In addition, similar to the rotating shaft 151 of the plug-in device 100 of the first embodiment, the illustration of the thread of the rotating shaft 351 of the plug-in device 300 of the third embodiment is omitted.
[0090] The load portions 110 of the load portion pair move symmetrically in the Z-axis direction. As a more specific example, the plug-in drive unit 350 causes the load portion pair to meander away from each other in the Z-axis direction, thereby applying loads to the multiple test boards 10 in sequence, and inserting the electrical connection portions 11 of the test device 50 in sequence for the multiple test boards 10. Similarly, the plug-in drive unit 350 causes the load portion pair to meander toward each other in the Z-axis direction, thereby applying loads to the multiple test boards 10 in sequence, and pulling out the electrical connection portions 11 of the multiple test boards 10 from the electrical connectors 53 of the test device 50 in sequence.
[0091] As another specific example, the plug-in drive unit 350 causes the pair of load parts to meander in a manner of approaching each other in the Z-axis direction, thereby applying loads to the plurality of test boards 10 in sequence, and inserting the electrical connection parts 11 of the plurality of test boards 10 in sequence into the electrical connectors 53 of the test device 50. Similarly, the plug-in drive unit 350 causes the pair of load parts to meander in a manner of moving away from each other in the Z-axis direction, thereby applying loads to the plurality of test boards 10 in sequence, and removing the electrical connection parts 11 of the plurality of test boards 10 in sequence from the electrical connectors 53 of the test device 50.
[0092] According to the plugging and unplugging device 300 of the third embodiment, the same effect as that of the plugging and unplugging device 100 of the first embodiment can be achieved. In addition, in the plugging and unplugging device 300 of the third embodiment, the initial position of each load portion 110 of the load portion pair in the Z-axis direction may be the upper end side and the lower end side of the rotation shaft 351 in the Z-axis direction, or may be near the center of the rotation shaft 351 in the Z-axis direction.
[0093] Fig. 20 and Fig.21 This is a schematic side view for explaining the configuration of the load portion 410 of the plugging device 400 of the fourth embodiment using a comparative example. As a difference from the plugging device 100 of the first embodiment, the plugging device 400 of the fourth embodiment does not include the first load portion 120 and the second load portion 130 that are offset from each other in the Z-axis direction, but instead includes the first load portion 420 and the second load portion 430 that are substantially in the same position in the Z-axis direction. In addition to the first load portion 420 and the second load portion 430 that are substantially in the same position in the Z-axis direction, the plugging device 400 of the fourth embodiment includes a plugging drive portion 450 having a second component 456 that can adjust the relative position of the first load portion 420 and the second load portion 430 in the X-axis direction.
[0094] The second component 456 may be a component such as a pantograph that can be extended and retracted in the X-axis direction and can be fixed to any length. Fig. 20 As shown, the relative positions of the first load portion 420 and the second load portion 430 can be pre-adjusted in the following manner, that is, while one of the first load portion 420 and the second load portion 430 applies a load to the end of a test plate 10, the other of the first load portion 420 and the second load portion 430 does not contact the test plate 10.
[0095] For example Fig.21 As shown in FIG. 1 , the relative positions of the first load portion 420 and the second load portion 430 are adjusted during at least one of the insertion and extraction operations in the following manner, that is, while one of the first load portion 420 and the second load portion 430 applies a load to the end of one test board 10, the other of the first load portion 420 and the second load portion 430 does not contact the one test board 10. In this case, Fig.21 As shown, for example, the track of the first load part 420 draws a larger stroke in the X-axis direction relative to the position of the second load part 430. It can also be said that one of the first load part 420 and the second load part 430 applies a load to the end of the test plate 10 while extending and retracting in the X-axis direction.
[0096] According to the plugging and unplugging device 400 of the fourth embodiment described above, the same effects as those of the plugging and unplugging device 100 of the first embodiment can be achieved.
[0097] Fig. 22 1 is a schematic top view showing a part of the plugging and unplugging device 500 of the fifth embodiment to which a plurality of test boards 10 are transferred and loaded in an enlarged manner. As a difference from the plugging and unplugging device 100 of the first embodiment, the plugging and unplugging device 500 of the fifth embodiment does not include a load portion 110 having a rotation mechanism 121, 131 including a rotation member 123, 133 that rotates around an axis orthogonal to the surface to which the load is applied to each test board 10, but includes a load portion 510 having a rotation mechanism 511 including a rotation member 513 that rotates around an axis parallel to the surface to which the load is applied to each test board 10. The rotation member 513 can make line contact with the surface to which the load is applied to each test board 10.
[0098] According to the plugging and unplugging device 500 of the fifth embodiment described above, the same effects as those of the plugging and unplugging device 100 of the first embodiment can be achieved.
[0099] In the above multiple embodiments, the fixed channel and the second component may also have a guide rail of a wavy track extending in a winding direction along the Z-axis direction, and a slider engaged in a manner capable of moving in the guide rail, instead of a cam groove of the wavy track extending in a winding direction along the Z-axis direction, and a cam follower sliding in the cam groove.
[0100] In the above multiple embodiments, the plugging and unplugging device can also perform the insertion or unplugging action of 2 or 3 test boards at a time.
[0101] In the above multiple embodiments, the test board is described as having a substantially square shape in a top view, and the two ends in the X-axis direction are planes. The shape of the test board may also be other shapes, and the two ends in the X-axis direction may be, for example, concave and convex, or may be curved. In this case, the load-bearing portion may, for example, be in point contact or surface contact with the protruding portions on the two ends in the X-axis direction of the test board while applying the load, for example, may be in point contact or surface contact with the portions protruding from the two ends in the X-axis direction of the test board while applying the load.
[0102] The present invention has been described above using the embodiments, but the protection scope of the present invention is not limited to the scope described in the above embodiments. It is obvious to those skilled in the art that various changes or improvements can be applied to the above embodiments. It can be seen from the description of the claims that such changed or improved embodiments can also be included in the protection scope of the present invention.
[0103] It should be noted that the execution order of the actions, steps, steps and stages in the devices, systems, programs and methods shown in the claims, specifications and drawings can be implemented in any order unless it is specifically noted as "before...", "prior to...", etc., and the output of the previous process is not used in the subsequent process. Even if the action flow in the claims, specifications and drawings is described using "first," "second," etc. for convenience, it does not mean that it must be implemented in this order.
