DETAILED DESCRIPTION

[0033] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0034] It should be noted that the terms used herein are only intended to describe specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that the terms "comprise" and / or "include" as used in the specification mean the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] The foregoing merely illustrates the principles of the application. Various modifications and alterations to the methods and devices described herein will become apparent to those skilled in the art from the foregoing description. It will be understood that the drawings and descriptions herein are by illustration as the dimensions of the various parts are not necessarily to scale. The principles of the application can be employed in any device, method or system that it is desired to improve. Accordingly, the application is not intended to be limited to the examples described herein, but is to be accorded the full scope consistent with the language of the claims, wherein reference to an element in the singular is not intended to mean "one and only one" unless specifically so stated, but rather "one or more." Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The breadth and scope of the present application should not be limited by any of the above-described example embodiments, but should be defined in accordance with the claims and their equivalents.

[0036] It should be noted that there are many components on the mainboard that need to be tested, and these components to be tested are arranged on the front and back of the mainboard. When testing the mainboard, it is necessary to test as many components on the mainboard as possible at the same time.

[0037] In order to facilitate testing and loading and unloading, in the conventional mainboard testing device, the mainboard is arranged horizontally on the bearing component, and corresponding testing components are arranged on both sides of the bearing component. For example, testing components for testing the interfaces of the mainboard are arranged on one side, and testing needles for testing the mainboard are arranged on the other side.

[0038] During testing, the bearing component and the mainboard are lifted by independent drivers and moved to the side of the interface testing components, so that the interface testing components are in contact with the corresponding interfaces of the mainboard to achieve testing. At the same time of lifting and moving, the testing needles are lifted by another independent driver, and when the mainboard is in place, the testing needles will also be in contact with the mainboard to achieve testing. After completing the testing, the bearing component and the testing needles are reset to replace the mainboard.

[0039] This testing device needs to be provided with at least two independent drivers to lift the bearing component and the testing needles respectively, resulting in a large device volume and low space utilization.

[0040] In order to reduce the volume and improve the space utilization, in the prior art, there is also a testing device provided with a three-layer structure, which only needs one driver to achieve lifting driving. For example, the device includes upper, middle and lower three-layer stacked carrier plates. The upper carrier plate is used to arrange the interface testing components, which are fixed in the height direction; the middle carrier plate is used to arrange the mainboard; and the lower carrier plate is floatingly connected with the middle carrier plate by springs, and the testing needles are arranged on the lower carrier plate.

[0041] In the test, only the lower layer of the carrier plate, the middle layer of the carrier plate and the mainboard are moved together by the driver. After the mainboard is in place, on the one hand, the mainboard can be in contact with the interface test components on the upper layer of the carrier plate to realize interface test; on the other hand, under the action of the force of the upper layer of the carrier plate and the driver below, the spring between the lower layer of the carrier plate and the middle layer of the carrier plate is compressed, so that the lower layer of the carrier plate is relative to the middle layer of the carrier plate, so that the test needle contacts the mainboard to realize the test. After the test is completed, the driver is reset to replace the mainboard.

[0042] The test device effectively reduces the size of the device and improves the space utilization of the device by eliminating the driver of the test needle. However, the mainboard has a relatively large area, and a large number of springs are usually arranged between the lower layer of the carrier plate and the middle layer of the carrier plate to realize floating support. Designers find that it is difficult to ensure the consistency of the compression of springs at different positions in actual testing. In the case that the spring floating force is uneven, the test needles at different positions will be inclined to different degrees, which makes it difficult for the test needles to stably and reliably contact the parts of the mainboard that need to be contacted, affecting the test efficiency.

[0043] In addition, in the case of inclined insertion of the test needle, the possibility of damage to the test needle is greatly increased. In the face of damaged test needles, in the case of maintenance and replacement, a lot of time is needed to disassemble and install the floating connection structure. This also leads to relatively low test efficiency and relatively high test cost.

[0044] In order to solve the above problems, referring to Figure 1 and Figure 2 The present application provides a linkage test device, which comprises a carrier 10, a first transmission member 21 and a second transmission member 31.

[0045] The carrier 10 comprises a carrier seat 11 and a test seat 12. The carrier seat 11 is used to set the target test piece 1111. In the test, the target test piece 1111 is placed on the carrier surface of the carrier seat 11. Preferably, the target test piece 1111 is set as the mainboard to be tested.

[0046] The test seat 12 is movably connected to the carrier seat 11, and the test seat 12 can be switched between the first separation position and the first detection position relative to the carrier seat 11. Those skilled in the art can set different movable connection structures according to actual needs to realize the movable connection of the test seat 12 and the carrier seat 11, as long as the test seat 12 can be switched between the first separation position and the first detection position relative to the carrier seat 11.

[0047] Exemplarily, the bearing seat 11 comprises a bearing plate 111 and a bearing box 112 which are connected. Wherein, the target test piece 1111 is arranged on the bearing surface of the bearing plate 111, and the bearing box 112 is arranged on the side of the bearing plate 111 away from the target test piece 1111.

[0048] On the bearing surface of the bearing plate 111, a person skilled in the art can set a limiting structure according to actual needs, such as a limiting block, a limiting shaft, a limiting recess, etc., to realize the limiting of the target test piece 1111.

[0049] Preferably, each limiting structure on the bearing surface is only used for limiting the target test piece 1111 in any direction perpendicular to the target direction DO. Of course, in some embodiments, the target test piece 1111 can also be completely positioned by the limiting structure on the bearing surface.

[0050] In the case of setting a limiting structure to realize the limiting of the target test piece 1111, a person skilled in the art can set a corresponding structure on the limiting structure according to actual needs to improve work efficiency. Exemplarily, a guide slope can be set so that the target test piece 1111 can be more smoothly put into the limiting structure to realize the limiting.

[0051] Preferably, the bearing plate 111 and the bearing box 112 are detachably connected. A person skilled in the art can set the detachable connection mode of the two according to actual needs, such as clamping connection or threaded connection, etc.

[0052] In succession, an active space is arranged in the bearing box 112, and the test seat 12 is movably arranged in the active space. For example, it can move along a straight line or along a curve. In some embodiments, the bearing box 112 can be arranged as an integrated structure, or as a detachable connection structure comprising multiple components.

[0053] Preferably, the test seat 12 is only movable relative to the bearing box 112 along the target direction DO. In any direction perpendicular to the target direction DO, the test seat 12 can be gap-fitted with the bearing box 112, or be provided with a corresponding guide structure to realize limiting and guiding. Of course, attention should be paid to avoid the test seat 12 from being separated from the bearing box 112 during testing. How to avoid separation belongs to the common knowledge of a person skilled in the art, and will not be described here.

[0054] In some embodiments, the target direction DO is parallel to the thickness direction of the mainboard, that is, the first separation position and the first detection position are sequentially and spaced apart along the target direction DO.

[0055] The test seat 12 is provided with test components 121. Preferably, the test components 121 are test pins for testing the mainboard. When the test seat 12 moves relative to the bearing seat 11, the test pins can be separated from or contacted with the mainboard.

[0056] Specifically, when the test seat 12 is switched to the first separation position relative to the bearing seat 11, the test components 121 on the test seat 12 are separated from the target test pieces 1111 on the bearing seat 11; when the test seat 12 is switched to the first detection position relative to the bearing seat 11, the test components 121 on the test seat 12 are contacted with the target test pieces 1111 on the bearing seat 11.

[0057] It can be understood that, taking the height direction as an example, the first separation position can be arranged above the first detection position, or below the first detection position.

[0058] When the first separation position is arranged above the first detection position, the position switching of the bearing seat 10 from the first separation position to the first detection position is relative to the ground, i.e. downward. Conversely, when the first separation position is arranged below the first detection position, the position switching of the bearing seat 10 from the first separation position to the first detection position is relative to the ground, i.e. upward.

[0059] Of course, in addition to arranging the bearing seat 11 as a combination of the bearing plate 111 and the bearing box 112, those skilled in the art can also arrange it as other structures according to actual needs. For example, in some embodiments, the test seat 12 is not arranged inside the bearing seat 11, at this time, the bearing seat 11 is arranged as a semi-open structure, and the test seat 12 is slidably connected with the bearing seat 11 through a corresponding guide structure.

[0060] By movably connecting the bearing seat 11 and the test seat 12, compared with the connection mode through the floating connection structure in the prior art, the difficulty of disassembling the two can be effectively reduced, so as to facilitate the corresponding maintenance work of the staff and improve the maintenance work efficiency.

[0061] Taking the bearing plate 111 as an example, those skilled in the art can arrange test through holes 1112 or hollow structures on the bearing plate 111 according to actual needs, so as to facilitate the test components 121 to contact the target test pieces 1111.

[0062] Taking the test pin as an example, when the test through hole 1112 is arranged, the test pin and the test through hole 1112 are coaxially arranged and gap-fitted, so that the test pin can pass through the test through hole 1112 and contact the mainboard.

[0063] In the case of setting the hollowed-out part, the number, size and distribution position of the hollowed-out part can be set according to actual needs by those skilled in the art to adapt to the same type of mainboard or be compatible with different types of mainboard.

[0064] In some embodiments, elastic components can be arranged between the carrier seat 11 and the test seat 12 so that the test seat 12 can more smoothly realize position switching to separate the test component 121 from the target test piece 1111 after the test is completed.

[0065] In order to realize the driving of the test seat 12 and the carrier seat 11, the first transmission member 21 and the second transmission member 31 need to be used. The first transmission member 21 and the second transmission member 31 are both in driving connection with the carrier 10.

[0066] Those skilled in the art can set the specific connection objects of the two transmission members according to actual needs.

[0067] For example, the first transmission member 21 is in driving connection with the test seat 12, and the second transmission member 31 is in driving connection with the carrier seat 11. Alternatively, the first transmission member 21 is in driving connection with the carrier seat 11, and the second transmission member is in driving connection with the test seat 12.

[0068] The first transmission member 21 is used to drive the test seat 12 to switch positions between the first separation position and the first detection position when moving. The second transmission member 31 is used to drive the carrier 10 to switch positions between the second separation position and the second detection position when moving.

[0069] Preferably, the two transmission members are arranged on a base surface, which can be the ground or a certain horizontal end surface. Preferably, the carrier 10 can only move in the target direction D0 relative to the base surface. In this case, the second separation position and the second detection position are arranged in sequence in the target direction D0.

[0070] It can be understood that, for example in the height direction, the second separation position can be arranged above the second detection position, or below the second detection position.

[0071] In the case where the second separation position is arranged above the second detection position, the position switching of the carrier 10 from the second separation position to the second detection position is relatively close to the ground and downward. Conversely, in the case where the second separation position is arranged below the second detection position, the position switching of the carrier 10 from the second separation position to the second detection position is relatively far from the ground and upward.

[0072] In the second detection position, the skilled person in the art can set a limiting seat 60 according to actual needs, and the limiting seat 60 cooperates with the bearing seat 11 to limit the target test piece 1111 in the direction parallel to the target direction D0, so as to position the target test piece 1111, so that the test component 121 can accurately contact the test part of the target test piece 1111.

[0073] Of course, in some embodiments, the skilled person in the art can also set other testers on the limiting seat 60. For example, a tester for testing the mainboard interface is set on the limiting seat 60 to test the mainboard interface together in the second detection position.

[0074] It can be understood that the second transmission member 31 drives the bearing seat 11 and the test seat 12 to move together, and of course, when testing, the target test piece 1111 on the bearing seat 11 will also move together.

[0075] Taking the limiting seat 60 in the second detection position as an example, when the bearing member 10 is switched to the second separation position, the distance between the bearing member 10 and the limiting seat 60 is relatively long, and there is a relatively large space between them. At this time, the worker can conveniently replace the target test piece 1111 and realize the maintenance of each component on the device.

[0076] When the bearing member 10 is switched to the second detection position, the distance between the bearing member 10 and the limiting seat 60 is shortened, and the space between them is smaller. At this time, the target test piece 1111 is completely positioned under the cooperation of the bearing seat 11 and the limiting seat 60.

[0077] Preferably, in some embodiments, the skilled person in the art can set corresponding guide structures for the position switching of the bearing member 10 to realize guidance and improve structural stability.

[0078] In the process of switching the bearing member 10 from the second separation position to the second detection position by the second transmission member 31, the first transmission member 21 moves synchronously with the second transmission member 31. Preferably, the synchronous movement direction of the two is parallel.

[0079] The skilled person in the art can set the synchronous movement mode of the two transmission members according to actual needs. For example, the first transmission member 21 and the second transmission member 31 are connected by a certain component, or the first transmission member 21 and the second transmission member 31 are directly connected to realize the synchronous movement of the first transmission member 21 and the second transmission member 31.

[0080] The skilled person in the art can set the driving mode of the two transmission members according to actual needs. For example, a cylinder or an electric motor cooperating with a screw rod and the like can be set to realize driving. Of course, manual pushing and pulling can also be used to realize driving.

[0081] Preferably, in some embodiments, a person skilled in the art can set corresponding guide structures for the movement of the two transmission members to realize guiding and improve structural stability.

[0082] Subsequently, the test seat 12 is switched to the first separation position when the carrier 10 is switched to the second separation position. In the process that the second transmission member 31 drives the carrier 10 to switch from the second separation position to the second detection position, the first transmission member 21 moves synchronously with the second transmission member 31. When the carrier 10 is switched to the second detection position, the test seat 12 is switched to the first detection position, so that the test component 121 contacts the target test member 1111 to realize detection.

[0083] A person skilled in the art can set the first transmission member 21 of different structures according to actual needs to realize the switching of the position of the test seat 12, as long as it can be ensured that the test seat 12 will not be switched to the first detection position when the carrier seat 11 is not switched to the second detection position. Similarly, a person skilled in the art can set the second transmission member 31 of different structures according to actual needs to realize the switching of the position of the carrier 10.

[0084] Preferably, the test seat 12 is switched to the first separation position synchronously when the carrier seat 11 is switched to the second separation position.

[0085] Of course, a person skilled in the art can also adjust the number of the two transmission members according to actual needs, for example, set the first transmission member 21 to one or more, set the second transmission member 31 to one or more, etc.

[0086] By setting the first transmission member 21 and the second transmission member 31 to move synchronously, the switching of the positions of the carrier 10 and the test seat 12 is realized, which can effectively replace the test device in the prior art which is provided with multiple drivers and a floating connection structure, and has high space utilization and stability.

[0087] Specifically, the linkage test device disclosed by the present application realizes the switching of the positions of the carrier 10 and the test seat 12 through the cooperation of the small-volume first transmission member 21 and the second transmission member 31. Although the first transmission member 21 and the second transmission member 31 also occupy a certain volume, compared with the test device provided with multiple drivers, the volume of the two transmission members is relatively small. Therefore, the volume of the linkage test device disclosed by the present application is relatively reduced as a whole, which effectively improves the space utilization.

[0088] Meanwhile, through the mechanical transmission cooperation of the first transmission member 21 and the second transmission member 31, the problem of uneven force in the floating connection structure in the prior art can be effectively avoided, so as to ensure that the test component 121 does not tilt and contact the target test piece 1111, and is very stable and reliable.

[0089] In the case that the test component 121 and the target test piece 1111 are correctly contacted, on the one hand, repeated debugging tests are no longer needed, the test times are effectively reduced, and the test efficiency is improved. On the other hand, the possibility of damage to the test component 121 or the target test piece 1111 is reduced, thereby reducing the test cost.

[0090] For example, in some embodiments, the first transmission member 21 is in transmission connection with the test seat 12, and the second transmission member 31 is in transmission connection with the bearing seat 11.

[0091] When testing, first, the first transmission member 21 and the second transmission member 31 are controlled to move synchronously. Under the transmission of the second transmission member 31, the bearing seat 11 drives the test seat 12 to move together, so that the bearing 10 is switched to the second separation position; at the same time, under the transmission of the first transmission member 21, the test seat 12 actively moves relative to the bearing seat 11, so that the test seat 12 is switched to the first separation position. After being in place, the mainboard is arranged on the bearing seat 11.

[0092] Secondly, the first transmission member 21 and the second transmission member 31 are controlled to move synchronously, so that the bearing 10 and the test seat 12 in the bearing seat 11 are switched in position. On the one hand, the bearing seat 11 drives the test seat 12 to move together, so that the bearing 10 is switched from the second separation position located below to the second detection position located above. On the other hand, the test seat 12 actively moves relative to the bearing seat 11, so that the test seat 12 is switched from the first separation position located below to the first detection position located above.

[0093] Finally, in the case that the first transmission member 21 and the second transmission member 31 are moved to be in place, so that the test seat 12 is switched to the first detection position and the bearing 10 is switched to the second detection position, the test component 121 on the test seat 12 is in contact with the mainboard on the bearing seat 11, and the lifting linkage test is realized.

[0094] For example, in some embodiments, the first transmission member 21 is in transmission connection with the bearing seat 11, and the second transmission member 31 is in transmission connection with the test seat 12.

[0095] When testing, first, the first transmission member 21 and the second transmission member 31 are controlled to move synchronously. Under the transmission of the second transmission member 31, the test seat 12 drives the carrier seat 11 to move as a whole, so that the carrier 10 is switched to the second separation position; meanwhile, under the transmission of the first transmission member 21, the carrier seat 11 is actively moved relative to the test seat 12, so that the test seat 12 is switched to the first separation position. After being in place, the mainboard is arranged on the carrier seat 11.

[0096] Secondly, the first transmission member 21 and the second transmission member 31 are controlled to move synchronously, so that the carrier 10 and the test seat 12 in the carrier seat 11 are switched in position. On the one hand, the test seat 12 drives the carrier seat 11 to move as a whole, so that the carrier 10 is switched from the second separation position located above to the second detection position located below. On the other hand, the carrier seat 11 is actively moved relative to the test seat 12, so that the test seat 12 is switched from the first separation position located above to the first detection position located below.

[0097] Finally, when the first transmission member 21 and the second transmission member 31 are moved to a position where the test seat 12 is switched to the first detection position and the carrier 10 is switched to the second detection position, the test component 121 on the test seat 12 is in contact with the mainboard on the carrier seat 11, so that the jacking linkage test is realized.

[0098] To sum up, the linkage test device disclosed by the application realizes the switching of the positions of the carrier 10 and the test seat 12 through the transmission cooperation of the first transmission member 21 and the second transmission member 31. Compared with the test device in the prior art, on the one hand, the volume of the entire device is effectively reduced through the two transmission members with small volumes, and the space utilization of the device is improved. On the other hand, through the transmission cooperation of the two transmission members, the problem of uneven stress during testing is effectively avoided, and it is ensured that the test component 121 can stably and reliably contact the target test piece 1111. In addition, the test efficiency is improved to a certain extent, and the test cost is reduced.

[0099] Referring to Figures 2 to 6 The linkage test device disclosed by the application realizes the jacking test on the target test piece 1111 in some embodiments. At this time, the first separation position is arranged below the first detection position, and the second separation position is also arranged below the second detection position.

[0100] The first transmission member 21 comprises a first part 211 and a second part 212 arranged in sequence, and the test seat 12 is provided with a first guide wheel 122. Of course, in some embodiments, the first transmission member 21 can be arranged as a guide wheel, and the same structure as the first part 211 and the second part 212 can be arranged on the test seat 12 to contact the guide wheel.

[0101] The first guide wheel 122 is movably connected to the first transmission member 21, and the movably connected includes sliding connection, rolling connection, and combined sliding and rolling connection. In some cases, the first guide wheel 122 and the first transmission member 21 can be separated first and then connected, or connected first and then separated. Preferably, the axial direction of the first guide wheel 122 is perpendicular to the moving direction of the first transmission member 21.

[0102] Specifically, the first part 211 can be provided as an end face or a slope face. In the case where the action to be implemented is the jacking action, the highest height of the first part 211 can be set to be not higher than the lowest height of the second part 212, or the highest height of the first part 211 can be set to be lower than the highest height of the second part 212.

[0103] In some embodiments, the first part 211 is provided as an end face, and the height of each part of the end face is equal and lower than the lowest height of the second part 212.

[0104] It should be noted that, in the case where the first guide wheel 122 is arranged at the first part 211, the person skilled in the art can arrange the first guide wheel 122 to be in contact with or separated from the end face of the first part 211.

[0105] It can be understood that, in the case where the first guide wheel 122 is arranged at the first part 211, the test seat 12 is switched to the first separated position, so that the test component 121 is separated from the target test piece 1111.

[0106] The second part 212 includes a first slope face 2121 and a first end face 2122 connected to each other. The first slope face 2121 is a transition face, so that the first guide wheel 122 moves between the first part 211 and the first end face 2122. In the case where the first guide wheel 122 is arranged at the first slope face 2121, the test seat 12 is also arranged between the first separated position and the first detection position.

[0107] The person skilled in the art can arrange the first slope face 2121 as an inclined plane, an inclined convex face, or an inclined concave face according to actual needs, as long as the first guide wheel 122 can move between the first part 211 and the first end face 2122. Preferably, the first slope face 2121 and the first end face 2122 are connected through an arc face.

[0108] Preferably, the first end face 2122 is a horizontal face, so as to provide support for the first guide wheel 122. In the case where the first guide wheel 122 is arranged at the first end face 2122, the test seat 12 is switched to the first detection position, and the test component 121 can maintain contact with the target test piece 1111 to implement the test.

[0109] The second transmission member 31 comprises a second end surface 311, a second slope surface 312 and a third end surface 313 arranged in sequence, and the bearing seat 11 is provided with a second guide wheel 1122. Of course, in some embodiments, the second transmission member 31 can be arranged as a guide wheel, and the bearing seat 11 is provided with the same structure as the second end surface 311, the second slope surface 312 and the third end surface 313 to contact the guide wheel.

[0110] The second guide wheel 1122 is movably connected to the second transmission member 31, and the movable connection includes sliding connection, rolling connection, and combined connection of sliding and rolling. Preferably, the axial direction of the second guide wheel 1122 is perpendicular to the moving direction of the second transmission member 31.

[0111] Specifically, the second end surface 311 is a horizontal surface to provide support for the second guide wheel 1122. The height of the second end surface 311 is lower than that of the third end surface 313. When the second guide wheel 1122 is arranged on the second end surface 311, the bearing 10 is switched to the second separation position. Those skilled in the art can set the second slope surface 312 as an inclined plane, an inclined convex surface or an inclined concave surface according to actual needs.

[0112] The second slope surface 312 comprises a first slope section 3121 and a second slope section 3122 connected in sequence. The first slope section 3121 is connected to the second end surface 311, and the second slope section 3122 is connected to the third end surface 313. Preferably, the corresponding slope sections and end surfaces are connected through an arc surface.

[0113] Preferably, when the second guide wheel 1122 is arranged on the first slope section 3121, the first guide wheel 122 is arranged on the first part 211. At this time, the test seat 12 remains in the first separation position, and the bearing 10 is arranged between the second separation position and the second detection position, and relatively closer to the second separation position.

[0114] When the second guide wheel 1122 is arranged on the second slope section 3122, the first guide wheel 122 is arranged on the first slope surface 2121. At this time, the test seat 12 is arranged between the first separation position and the first detection position, and the bearing 10 is still arranged between the second separation position and the second detection position, and relatively closer to the second detection position.

[0115] When the second guide wheel 1122 is arranged on the third end surface 313, the first guide wheel 122 is arranged on the first end surface 2122. At this time, the test seat 12 is switched to the first detection position, and the bearing 10 is switched to the second detection position.

[0116] Taking the first guide wheel 122 and the second guide wheel 1122 with the same radial dimension as an example, and in the case that the test seat 12 is located in the first separation position, the heights of the two guide wheels remain consistent, the height of the first end surface 2122 can be set to be higher than that of the third end surface 313.

[0117] Taking the start of the lifting test as an example, the first transmission component 21 and the second transmission component 31 move synchronously, causing the second guide wheel 1122 to move from the second end face 311, through the first slope section 3121 and the second slope section 3122 to the third end face 313. At the same time, the first guide wheel 122 moves from the first part 211, through the first slope 2121 to the first end face 2122. Correspondingly, the test seat 12 will switch from the first separation position to the first detection position, and the carrier 10 will switch from the second separation position to the second detection position.

[0118] Conversely, the test seat 12 is switched from the first detection position to the first separation position, and the carrier 10 is switched from the second detection position to the second separation position.

For example, the driving member 40 can be set as a cylinder, or as a combination of a motor and a screw rod, etc. to realize driving. The third transmission member 41 is connected to the driving end of the driving member 40 and the first transmission group 20 and the second transmission group 30 respectively. Under the transmission of the third transmission member 41, the driving force of the driving member 40 is transmitted to the two transmission groups, thereby driving the carrier seat 11 and the test seat 12 to move.

Meanwhile, along the first direction D1, the fourth transmission member 43 and the third transmission member 41 are arranged on the two sides of the driving member 40 respectively. This structure makes each transmission member connected to each other to form a square structure, so as to further increase the structural stability.

Preferably, the first guide member 42 is provided with two guide rails which are fixedly arranged, and the guide block is fixedly connected to the second transmission member 31 to realize the guidance along the first direction D1 and increase the structural stability of the device.

[0130] Referring to Figure 8 and Figure 9 The linkage test device of the present application is provided with a first elastic member 123 on the test seat 12 in some embodiments. The first elastic member 123 is used to provide a first elastic force for the test seat 12, and the first elastic force is used to move the test seat 12 from the first detection position to the first separation position.

Of course, in some embodiments, the first elastic component 123 can also be arranged on the bearing plate 111 of the bearing seat 11.

[0132] After the detection of the target test piece 1111 is completed, the driving end of the driving member 40 reversely moves to reset each component. The first elastic component 123 is arranged to provide the first elastic force for the test seat 12, so that the test seat 12 can move more smoothly, and problems such as jamming can be avoided, and the test efficiency of the device is effectively improved.

[0133] Referring to FIGS. 1 to 5, Figure 1 Figure 7 and Figure 10 The linkage test device of the present application further comprises a second guide member 50 in some embodiments. The second guide member 50 comprises a guide column 51, a guide sleeve 52, and a second elastic component 53.

The guide sleeve 52 is movably arranged on the guide column 51, and the guide sleeve 52 is connected to the bearing seat 11. When the bearing seat 11 moves, the guide sleeve 52 and the guide column 51 cooperate to guide the movement of the bearing seat 11, and the structural stability of the device is increased. Preferably, a through hole is arranged on the bearing box 112 to avoid the guide column 51.

[0135] The second elastic component 53 is connected to the guide column 51 and the guide sleeve 52, respectively. The second elastic component 53 is used to provide a second elastic force for the bearing member 10, and the second elastic force is used to move the bearing member 10 from the second separation position to the second detection position.

[0136] Those skilled in the art can set different types of second elastic components 53 according to actual needs, such as different types of springs. Preferably, the second elastic component 53 is set as a spring. Before testing, the driving end of the driving member 40 moves, so that each transmission member drives the bearing member 10 to move and switch to the second detection position. The second elastic component 53 is arranged to provide a second elastic force for the bearing member 10, so that the movement is more smooth, and a part of the weight of the bearing member 10 is effectively shared, so that the driving member 40 can more easily realize driving, and the test efficiency is effectively improved. After the test is completed, the second elastic force can also play a certain buffering role, so that the bearing member 10 does not move too fast and cause hard contact and damage, and the service life of each component is prolonged.​

[0137] The number and the setting position of the second guide 50 can be set by the person skilled in the art according to the actual requirement. Preferably, the second guide 50 is provided with four groups, and is arranged on the four corners of the square carrier 11 respectively, so as to increase the structural stability.

[0138] With reference to Figure 9 As shown in the drawings, in some embodiments, the test seat 12 is detachably connected with the carrier 11; or / and, the test component 121 is detachably connected with the test seat 12.

[0139] The person skilled in the art can detachably connect only the test seat 12 with the carrier 11, or only the test component 121 with the test seat 12 according to the actual requirement. Preferably, both the test seat 12 and the carrier 11 are detachably connected, and both the test component 121 and the test seat 12 are detachably connected.

[0140] The person skilled in the art can set the detachable connection mode between the components according to the actual requirement, for example, through the screw thread connection, clamping and the like, and the present application does not limit this.

[0141] In the detachable connection case, if part of the test component 121 is damaged after long time testing, the worker can replace it locally, so as to effectively reduce the maintenance cost.

[0142] The present application also provides a linkage test device, which comprises a limiting seat 60 and the linkage test device as described in any one of the above embodiments. The limiting seat 60 is used for cooperating with the carrier 11 to test the target test piece 1111 at the second detection position.

[0143] The person skilled in the art can set the limiting seat 60 according to the actual requirement. For example, the limiting seat 60 can be fixedly arranged at or near the second detection position, so as to cooperate with the carrier 10 moving to the second detection position, and to test the target test piece 1111. Alternatively, the limiting seat 60 can be movably arranged at or near the second detection position. For example, the limiting seat 60 can be connected with a corresponding driver, so that the limiting seat 60 is driven by the driver to move along the target direction DO, or is arranged in cooperation with a rotating structure such as a hinge to rotate relative to the second detection position, so as to provide more space when not needed for testing. The driver of the limiting seat 60 can be a cylinder, a motor, a hydraulic cylinder and the like, and will not be described herein.

[0144] The linkage test device described in the present application has the beneficial effects of the linkage test device described in the above embodiments, and thus the linkage test device also has all the beneficial effects, and will not be described herein.

[0145] In some embodiments, other testers can be provided on the limiting seat 60 by those skilled in the art. For example, a tester for testing the mainboard interface can be provided on the limiting seat 60 to test the mainboard interface together in the second detection position.

[0146] Referring to Figure 11 and Figure 12 In some embodiments of the linkage testing device, the limiting seat 60 is provided with a pressing member 61, which includes a pressing cylinder 611, a pressing rod 612, and a third elastic component 613.

The pressing rod 612 is movably connected to the pressing cylinder 611, specifically, the pressing rod 612 can move along its own axis relative to the pressing cylinder 611. The third elastic component 613 is connected to the pressing cylinder 611 and the pressing rod 612, respectively, and is used to provide a third elastic force for the pressing rod 612, which is used to move the pressing rod 612 from the end away from the target testing piece 1111 to the end close to the target testing piece 1111. Preferably, the third elastic component 613 is provided as a spring.

[0148] The end of the pressing rod 612 that contacts the target testing piece 1111 is provided with a pressing component 6121. Preferably, the pressing component 6121 is provided as a flexible / elastic component to avoid damaging the target testing piece 1111.

[0149] During testing, when the target testing piece 1111 moves to the second detection position, the pressing member 61 provides a pressing force for the target testing piece 1111 to ensure that the target testing piece 1111 remains flat.

[0150] When the target testing piece 1111 contacts the pressing component 6121, the pressing rod 612 and the pressing cylinder 611 cooperate to overcome the third elastic force, so that the pressing rod 612 moves from the end close to the target testing piece 1111 to the end away from the target testing piece 1111, achieving floating pressing and further avoiding damage to the target testing piece 1111. After the test is completed, the target testing piece 1111 is separated from the pressing component 6121, at which time, under the action of the third elastic force, the pressing rod 612 is reset, waiting for subsequent detection.

[0151] Preferably, the limiting seat 60 is provided with a plurality of pressing members 61, which are arrayed to provide uniform pressing force for the target testing piece 1111 to ensure that the target testing piece 1111 remains flat to improve detection accuracy.

[0152] Referring to Figure 13As shown, the linkage test device provided by the present application is provided with a first guide part 1121 on the carrying box 112, and a second guide part 62 corresponding to the first guide part 1121 on the limiting seat 60, so that the carrying part 10 and the limiting seat 60 are guided when the second guide part 62 contacts the first guide part 1121. By means of the structure, the clamping of the mold caused by the error can be guided, so that the corresponding parts can be accurately aligned and tested, and the test precision is improved.

[0153] Preferably, the first guide part 1121 is a guide hole, and the second guide part 62 is a guide pin, and the two are gap-fitted. Preferably, the limiting seat 60 is further provided with an abutting part 63, and when the abutting part 63 abuts against the carrying plate 111, the carrying plate 111 and the limiting seat 60 cannot be relatively close to each other, so as to avoid damaging the target test part 1111.

[0154] Reference Figure 14 As shown, the present application further provides a linkage test method applied to the linkage test device provided in any one of the above embodiments. The linkage test method comprises the following steps.

[0155] Controlling the first transmission part 21 and the second transmission part 31 to move synchronously. The first transmission part 21 and the second transmission part 31 are both transmission-connected to the carrying part 10, and the carrying part 10 comprises a carrying seat 11 and a test seat 12. The carrying seat 11 is used for setting a target test part 1111, and the test seat 12 is movably connected to the carrying seat 11, and the test seat 12 is provided with a test part 121.

[0156] The test seat 12 is switched from the first separation position to the first detection position by the movement of the first transmission part 21. When the test seat 12 is switched to the first separation position, the test part 121 is separated from the target test part 1111.

[0157] The carrying part 10 is switched from the second separation position to the second detection position by the movement of the second transmission part 31.

[0158] When the test seat 12 is switched to the first detection position and the carrying part 10 is switched to the second detection position, the test is realized by the contact between the test part 121 and the target test part 1111.

[0159] Working principle:

[0160] Before the test of the mainboard, the carrying seat 11 and the test seat 12 are switched to the second separation position and the first separation position respectively under the driving of the driving part 40. At this time, the mainboard is set on the carrying plate 111.

[0161] Then, under the drive of the driving member 40, the first transmission member 21 and the second transmission member 31 are controlled to move synchronously, so that the carrier 10 and the test seat 12 in the carrier seat 11 are switched in position. At this time, on the one hand, the second guide wheel 1122 moves from the second end surface 311 to the third end surface 313 through the first slope section 3121 and the second slope section 3122, so that the carrier 10 is switched from the second separation position located relatively below to the second detection position located relatively above. On the other hand, the first guide wheel 122 moves from the first part 211 to the first end surface 2122 through the first slope surface 2121, so that the test seat 12 is switched from the first separation position located relatively below to the first detection position located relatively above. In the process of moving and lifting, the first guide member 42, the second guide member 50, and the first guide part 1121 and the second guide part 62 cooperate to provide guidance.

[0162] When the first transmission member 21 and the second transmission member 31 move to the position, so that the test seat 12 is switched to the first detection position, and the carrier 10 is switched to the second detection position, the pressing member 61 on the limiting seat 60 presses the mainboard, and the test part 121 on the test seat 12 contacts the mainboard on the carrier seat 11, so that the test is realized. After the test is completed, each part is reset to replace the mainboard and perform subsequent tests.

[0163] For the convenience of description, spatial relative terms such as "above", "upper", "upper surface", "upper", etc. can be used herein to describe the spatial positional relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "above" other devices or structures will be positioned "below" or "below" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative description used herein is interpreted accordingly.

[0164] In addition, it should be noted that the use of the words "first", "second", etc. to define parts only facilitates the differentiation of corresponding parts, and the above words have no special meaning unless otherwise stated, and therefore cannot be understood as limiting the scope of protection of the present application.

[0165] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
