[0046] The test device provided by the present application can be used for electrical detection of devices such as power adapters for various signals, and can achieve quick wire replacement to detect different devices under test.

[0047] The following will describe the test device 100 provided by the present application in conjunction with the attached Figures 1 to 3 description.

[0048] The test device 100 includes a frame 10, a conveying device 20, and a test device 50.

[0049] The conveying device 20 is provided on the frame 10, and a plurality of clamps 30 are detachably provided in the conveying device 20. At least one clamping groove 31 is provided in the clamp 30 to clamp the device under test 40. The shapes of the clamping grooves 31 of the plurality of clamps 30 are different to be suitable for devices under test 40 of different shapes. The conveying device 20 is adapted to circulate and convey the clamps 30 between a plurality of set positions.

[0050] As Figure 1 and Figure 2 shown, a part of the conveying device 20 is fixedly connected to the frame 10, and a plurality of clamps 30 are provided on another part of the conveying device 20, and the other part of the conveying device 20 is movable relative to the frame 10. The conveying device 20 circulates and conveys the plurality of clamps 30 along the same set path. In the path where the conveying device 20 conveys the clamps 30, a plurality of set positions are included, and the plurality of set positions are arranged at intervals along the set path of the clamp 30 conveying, so that the plurality of clamps 30 sequentially pass through the plurality of set positions in the conveying device 20.

[0051] The fixture 30 is provided with a clamping groove 31. One end of the clamping groove 31 has an opening so that the device under test 40 can be accommodated in the clamping groove 31. The shape of the inner wall of the clamping groove 31 matches the shape of the outer shell of the device under test 40, so that the device under test 40 can be clamped in the clamping groove 31. Thus, the device under test 40 can be conveyed in the conveying device 20 along with the fixture 30.

[0052] The clamping grooves 31 in multiple fixtures 30 have various inner wall shapes, so that multiple fixtures 30 can be respectively suitable for fixing and transporting devices under test 40 with various outer shapes. The fixture 30 is detachably arranged on the conveying device 20. Thus, the device under test 40 applicable to the testing device 100 provided by the present application can be replaced by replacing the fixture 30, making the testing device 100 provided by the present application highly compatible with devices under test 40 with multiple outer shapes.

[0053] The testing device 50 is arranged on the frame 10. The testing device 50 is provided with a contact member 51. The multiple set positions include a testing position 202. The contact member 51 can be in abutting contact with the device under test 40 in the fixture 30 located at the testing position 202, so that the testing device 50 is electrically connected to the device under test 40. The position of the contact member 51 is adjustable to be suitable for abutting against devices under test 40 with different shapes.

[0054] As Figure 1 and [[ID= As shown, the testing device 50 is arranged on the frame 10 near some of the set positions. When the fixture 30 carrying the device under test 40 moves to the set position near the testing device 50, the contact member 51 in the testing device 50 is movable relative to the frame 10, that is, the contact member 51 is movable relative to the device under test 40 located at the set position. The contact member 51 can move towards the device under test 40 until it contacts the device under test 40. The testing device 50 is electrically connected to the device under test 40 through the contact member 51, so as to measure the electrical characteristics of the device under test 40 through the testing device 50.

[0055] During the process of the contact member 51 moving to contact the device under test 40, the contact member 51 moves from a state of being spaced from the device under test 40 to a state of contacting the device under test 40. Thus, the testing device 50 can abut against and be electrically connected to devices under test 40 with different outer shapes through the contact member 51, making the testing device 100 provided by the present application highly compatible with devices under test 40 with multiple outer shapes.

[0056] The beneficial effects of the test device 100 provided by this application are as follows: Compared with the prior art, on the one hand, in the test device 100 provided by this application, a plurality of fixtures 30 are detachably provided, and the clamping grooves 31 of the plurality of fixtures 30 have different shapes to adapt to the power adapters and other DUTs 40 with various shapes, so that the test device 100 provided by this application can achieve rapid line change for production lines of power adapters with multiple specifications. On the other hand, the test device 50 of the test device 100 provided by this application is connected to the DUT 40 through the contact member 51, and the contact member 51 is movable relative to the frame 10 so that the contact member 51 can abut against the DUTs 40 with different shapes, thereby enabling the test device 100 provided by this application to be applied to detect DUTs 40 with various shapes.

[0057] Referring ​ and ​ , in some embodiments provided by this application, the contact member 51 includes a first connection portion 511. The end of the first connection portion 511 facing the test position 202 is provided with a first probe group 5111 and a second probe group 5112. The test device 50 further includes a first driving member 52. The first driving member 52 is connected between the frame 10 and the first connection portion 511. The first driving member 52 can drive the first connection portion 511 to move along the first direction, so that the first probe group 5111 or the second probe group 5112 abuts and contacts the first port 411 of the DUT 40 in the fixture 30 located at the test position 202.

[0058] The arrangement direction of the first probe group 5111 is different from the arrangement direction of the second probe group 5112, so that the first probe group 5111 and the second probe group 5112 can respectively abut against the first ports 411 of DUTs 40 with different shapes.

[0059] As ​ and ​ shown, the DUT 40 has a first port 411. The first port 411 can be the AC plug of the power adapter. The end of the contact member 51 facing the DUT 40 is provided with a first probe group 5111 and a second probe group 5112. The first probe group 5111 and the second probe group 5112 can respectively abut and contact the first port 411 of the DUT 40, so that the contact member 51 is electrically connected to the DUT 40.

[0060] The first direction is the z - direction in the figure. The contact member 51 is disposed on one side of the device under test 40 facing the first direction z. The fixed end of the first driving member 52 is fixedly connected to the frame 10, and the movable end of the first driving member 52 is connected to the contact member 51. The distance between the fixed end and the movable end of the first driving member 52 in the first direction z is adjustable, so that the first driving member 52 can drive the contact member 51 to move along the first direction z to gradually approach the device under test 40 until one of the first probe group 5111 and the second probe group 5112 abuts against the first port 411 of the device under test 40.

[0061] In some embodiments, the first driving member 52 can include any one of linear motion drivers such as a cylinder, a hydraulic cylinder, a linear motor, etc.

[0062] There are two probes in the first probe group 5111 and two probes in the second probe group 5112. As ​ shown, the two probes in the first probe group 5111 are arranged along the second direction y, and the two probes in the second probe group 5112 are arranged along the third direction x. The first port 411 of the device under test 40 has different shapes, so that the first probe group 5111 and the second probe group 5112 can respectively abut against the first ports 411 of the device under test 40 with different shapes.

[0063] Thus, by driving the contact member 51 to move along the first direction z by the first driving member 52, so that any one of the first probe group 5111 or the second probe group 5112 abuts against the first port 411 of the device under test 40, and the arrangement directions of the first probe group 5111 and the second probe group 5112 are different, so that the test device 100 provided in the present application can be compatible with devices under test 40 with different outer shapes of the first port 411.

[0064] In some embodiments provided in the present application, a plurality of clamping grooves 31 are provided in the fixture 30. The plurality of clamping grooves 31 are parallel and arranged at a set interval. The first connecting portion 511 includes a plurality of first probe groups 5111 and a plurality of second probe groups 5112. The plurality of first probe groups 5111 are arranged along the arrangement direction of the plurality of clamping grooves 31 and are arranged at a set interval. The plurality of second probe groups 5112 are arranged along the arrangement direction of the plurality of clamping grooves 31 and are arranged at a set interval.

[0065] As ​ and ​ shown, the plurality of clamping grooves 31 in the fixture 30 are parallel and spaced along the third direction x, so that the fixture 30 can accommodate a plurality of devices under test 40 at the same time. The first connecting portion 511 includes a plurality of first probe groups 5111 arranged parallel along the third direction x and a plurality of second probe groups 5112 arranged parallel along the third direction x.

[0066] Two adjacent clamping grooves 31 have a set interval in the third direction x, that is, the intervals between the geometric centers of two adjacent clamping grooves 31 in the third direction x are all the set interval. Two adjacent first probes have a set interval in the third direction x, that is, the intervals between the geometric centers of two adjacent first probes in the third direction x are all the set interval. Two adjacent second probes have a set interval in the third direction x, that is, the intervals between the geometric centers of two adjacent second probes in the third direction x are all the set interval.

[0067] Thus, by the abutting contact between the contact member 51 and the device under test 40, multiple devices under test 40 are electrically connected to the test device 50 simultaneously, improving the detection efficiency of the test equipment 100 provided in this application.

[0068] In some embodiments provided in this application, the test device 50 further includes a second driving member 53. The second driving member 53 is connected between the frame 10 and the first connecting portion 511. The second driving member 53 can drive the first connecting portion 511 to move along the arrangement direction of the first probe group 5111 and the second probe group 5112, so that the first probe group 5111 or the second probe group 5112 moves to one side of the first port 411 of the device under test 40 in the fixture 30 located at the test position 202 along the first direction z.

[0069] The arrangement direction of the first probe group 5111 and the second probe group 5112 is the second direction y. As ​ and ​ shown, the second driving member 53 can include any one of linear motion drivers such as a cylinder, a hydraulic cylinder, and a linear motor, so as to drive the contact member 51 to move along the second direction y through the second driving member 53. The first probe group 5111 and the second probe group 5112 are arranged along the second direction y, and the first probe group 5111 and the second probe group 5112 can move along the second direction y under the drive of the second driving member 53, so that one of the first probe group 5111 and the second probe group 5112 can move to one side of the device under test 40 in the first direction z.

[0070] Before driving the contact member 51 to move along the first direction by the first driving member 52, the first probe group 5111 or the second probe group 5112 can be moved in the third direction by the second driving member 53, so as to move one of the first probe group 5111 and the second probe group 5112 to one side of the device under test 40 in the first direction z. When the first driving member 52 drives the contact member 51 to move along the first direction z, one of the first probe group 5111 and the second probe group 5112 located on one side of the device under test 40 in the first direction z can abut against the device under test 40.

[0071] Thus, on the one hand, the test device 100 provided by the present application has high compatibility with the DUTs 40 of multiple shapes. On the other hand, when the test device 100 provided by the present application switches between multiple batches of DUTs 40, there is no need to replace the probes, thereby saving the time for the test device 100 provided by the present application to switch between multiple batches of DUTs.

[0072] In some embodiments provided by the present application, the second driving member 53 is connected between the first driving member 52 and the frame 10, and the second driving member 53 can drive the first driving member 52 together with the first connecting portion 511 to move along the arrangement direction y of the first probe group 5111 and the second probe group 5112.

[0073] As ​ and ​ shown, the first driving member 52 includes a first fixing member 522 and a first moving member 521. The first moving member 521 can move relative to the first fixing member 522 along a first direction. The second driving member 53 includes a second fixing member 532 and a second moving member 531. The second moving member 531 can move relative to the second fixing member 532 along a second direction y. The second fixing member 532 is fixedly connected to the frame 10. The first fixing member 522 is connected to the second moving member 531, and the contact member 51 is connected to the first moving member 521.

[0074] Thus, the motion transmission in the first direction z and the second direction y is respectively realized through the second driving member 53 and the first driving member 52, so as to realize the movement of the contact member 51 in the first direction z and the second direction y by driving the second driving member 53 and the first driving member 52.

[0075] In some embodiments provided by the present application, the first driving member 52 includes a first fixing member 522 and a first moving member 521. The first fixing member 522 is connected to the frame 10, and the first moving member 521 is connected to the first connecting portion 511. The first moving member 521 can move relative to the first fixing member 522 in the first direction z.

[0076] A first limiting block 5221 is provided on the first fixing member 522, and a second limiting block 5211 is provided on the first moving member 521. The first limiting block 5221 and the second limiting block 5211 are arranged along the first direction z to abut against each other. An active limiting block 5212 is further provided on one of the first moving member 521 and the first fixing member 522. The active limiting block 5212 can be clamped between the first limiting block 5221 and the second limiting block 5211 to adjust the stroke of the first driving member 52.

[0077] As ​As shown, the first limiting block 5221 and the second limiting block 5211 are arranged along the first direction z. When the first movable member 521 moves relative to the first fixed member 522 in the first direction z, the first limiting block 5221 abuts against the second limiting block 5211, thereby limiting the stroke of the first movable member 521.

[0078] The movable limiting block 5212 is rotatably provided on the first movable member 521, so that the movable limiting block 5212 can rotate between the first limiting block 5221 and the second limiting block 5211. When the movable limiting block 5212 rotates between the first limiting block 5221 and the second limiting block 5211, the first limiting block 5221 can abut against the movable limiting block 5212 to shorten the stroke of the first movable member 521 moving relative to the first fixed member 522 in the first direction z. When the movable limiting block 5212 disengages from between the first limiting block 5221 and the second limiting block 5211, the first limiting block 5221 can directly abut against the second limiting block 5211 to increase the stroke of the first movable member 521 relative to the first fixed member 522.

[0079] Thus, the dimensions of the DUTs 40 with different shapes are different in the first direction z. By rotating the movable limiting block 5212, the stroke of the first movable member 521 relative to the first fixed member 522 can be adjusted, that is, the stroke of the contact member 51 moving in the first direction z can be adjusted, so that the moving stroke of the contact member 51 in the first direction z matches the DUTs 40 with various different shapes. On the one hand, the testing device 100 provided by the present application has high compatibility with the DUTs 40 of multiple shapes. On the other hand, compared with adjusting the stroke of the first driving member 52 by using tools to adjust the limit screw in the related art, the testing device 100 provided by the present application only needs to rotate the movable limiting block 5212 to adjust the stroke of the first driving member 52, without special tools and saving the time for the testing device 100 provided by the present application to switch between multiple batches of DUTs.

[0080] Referring to ​ , in some embodiments provided by the present application, the second driving member 53 includes a second fixed member 532 and a second movable member 531. The second fixed member 532 is connected to the frame 10, the first fixed member 522 is provided on the second movable member 531, and the second movable member 531 can move relative to the second fixed member 532 in the arrangement direction y of the first probe group 5111 and the second probe group 5112.

[0081] A third limiting block 5321 is provided on the second fixed member 532, and a fourth limiting block 5311 is provided on the second movable member 531. Part of the fourth limiting block 5️⃣11 can be blocked between the third limiting block 5321 and the second movable member 531, and the dimension of the part of the fourth limiting block 5311 blocked between the third limiting block 5321 and the second movable member 531 is adjustable to adjust the stroke of the second driving member 53.

[0082] like ​ and ​ As shown, the third limit block 5321 and at least part of the fourth limit block 5311 are arranged along the second direction y. When the second movable member 531 moves in the second direction y relative to the second fixed member 532, the third limit block 5321 can abut against part of the fourth limit block 5311 to limit the travel of the second movable member 531 in the second direction y.

[0083] The fourth limit block 5311 is rotatably provided on the second movable member 531, and the rotating shaft of the fourth limit block 5311 extends along the second direction y, and the fourth limit block 5311 is provided with a plurality of stop portions 5313 along the circumference of its rotation, and the plurality of stop portions 5313 are at different distances from the third limit block 5321 in the second direction y, that is, the distance between the ends of the plurality of stop portions 5313 close to the third limit block 5321 and the third limit block 5321 in the second direction y, and the fourth limit block 5311 can be rotated relative to the second movable member 531 so that any one of the plurality of stop portions 5313 is located on one side of the third limit block 5321 along the second direction y.

[0084] The fourth limit block 5311 also includes an elastic member 5312, and a limit groove 5314 is provided on the second movable member 531. The elastic member 5312 is pressed against the side of the multiple stop portions 2121 facing the third limit block 5321. The limit groove 5314 is provided on the side of the stop portion 2121 away from the elastic member 5312, so that the end of the stop portion 2121 away from the third limit block 5321 is pressed into the limit groove 5314 through the elastic member 5312, thereby limiting the fourth limit block 5311 from rotating along its circumferential direction.

[0085] Therefore, by rotating the fourth limit block 5311, the movement stroke of the second movable member 531 relative to the second fixed member 532 in the second direction y can be adjusted, that is, the movement stroke of the contact member 51 in the second direction y can be adjusted, so that the movement stroke of the contact member 51 in the second direction y can match a plurality of test pieces 40 with different shapes. On the one hand, the test equipment 100 provided in the present application has higher compatibility with a plurality of test pieces 40 with different shapes. On the other hand, compared with the related art in which the stroke of the second driving member 53 is adjusted by adjusting the limit screw using a tool, the test equipment 100 provided in the present application only needs to adjust the stroke of the second driving member 53 by rotating the fourth limit block 5311, without the need for special tools and saving the time of the test equipment 100 provided in the present application in switching between multiple batches of test pieces.

[0086] Reference ​, in some embodiments provided by the present application, a plurality of connectors 211 are provided on the conveying device 20.

The second ports 421 of the plurality of devices under test 40 in the jig 30 are all connected to the first contacts 2111 of the connectors 211. In some embodiments, the second ports 421 of the plurality of devices under test 40 in the jig 30 are connected to the plurality of first contacts 2111 in one-to-one correspondence.

[0088] The testing device 50 includes a third driving member 54.

The third driving member 54 can drive the second connecting portion 512 to move along the first direction x and the second direction y, so that the second contact 5121 abuts and connects with the first contact 2111.

[0089] As ​ and ​ shown, the third driving member 54 includes a free end and a fixed end. The fixed end of the third driving member 54 is fixedly connected to the frame 10. The second connecting portion 512 is provided at the free end of the third driving member 54. After the jig 30 moves to a set position and stops moving, the third driving member 54 includes a cylinder arranged along the first direction x and a cylinder arranged along the second direction y. The second connecting portion 512 is driven to move along the first direction x by the cylinder arranged along the first direction x, and the second connecting portion 512 is driven to move along the second direction y by the cylinder arranged along the second direction y, so that the second connecting portion 512 moves in the direction towards the connector 211, so that the second contact 5121 of the second connecting portion 512 is connected to the first contact 2111 of the connector 211, thereby realizing the electrical connection between the testing device 50 and the second port 421 of the device under test 40, for the testing device 50 to test the electrical characteristics of the device under test 40.

[0090] The third driving member 54 and the second connecting portion 512 are both located on one side of the moving path of the connecting member 211, so that after the tested member 40 at the test position 202 is tested, the second connecting portion 512 is disengaged from the connecting member 211 and moves out of the moving path of the connecting portion to avoid the connecting member 211.

[0091] Thus, the DC output terminals of multiple tested members 40 are electrically connected to the testing device 50 through the connecting member 211 and the second connecting portion 512, reducing the process of repeatedly plugging and unplugging the DC output terminals of the tested members 40, thereby improving the testing efficiency of the testing device 100 provided in the present application.

[0092] In some embodiments provided in the present application, the connecting member 211 is detachably connected to the conveying device 20.

The shapes of the sockets on the multiple connecting members 211 are different, so that the multiple connecting members 211 can be respectively connected to the tested members 40 with different outer shapes of the second ports 421.

[0093] Thus, by disassembling and replacing the connecting member 211 on the conveying device 20, the connecting member 211 on the conveying device 20 can be made to match the tested members 40 with different outer shapes of the second ports 421, so that the testing device 100 provided in the present application has high compatibility with the tested members 40 of multiple outer shapes.

[0094] In some embodiments provided in the present application, there are multiple test positions 202 and multiple testing devices 50, and the multiple testing devices 50 are arranged in one-to-one correspondence with the multiple test positions 202.

The comprehensive testing device 502 is correspondingly arranged at the comprehensive test position 2022 to perform a comprehensive test on the tested member 40 in the fixture 30 located at the comprehensive test position 2022 to ensure the product performance, safety, reliability and compliance with relevant standards.

[0096] Thus, the testing device 100 provided in the present application can perform various tests on the tested member 40, reducing the clamping times and thus improving the testing efficiency of the tested member 40.

[0097] In some embodiments provided by the present application, the multiple set positions further include a loading position 201 and an unloading position 203, and the multiple test positions 202 are located between the loading position 201 and the unloading position 203.

The unloading device 60 is correspondingly arranged at the unloading position 203. The unloading device 60 is adapted to take out the workpiece under test 40 in the fixture 30 located at the unloading position 203 and convey it to the subsequent process station.

[0099] Thus, the multiple test positions 202 are located between the loading position 201 and the unloading position 203, so that during the process of the workpiece under test 40 being clamped in the fixture 30 located at the loading position 201 to being taken out from the fixture 30 located at the unloading position 203, the workpiece under test 40 passes through the multiple test positions 202 under the conveyance of the conveying device 20 to complete the detection process of the workpiece under test 40.

A positioning boss 32 is provided on the side of the fixture 30 facing the seat body 212. The dimension of the positioning boss 32 in the third direction x is the same as the dimension of the positioning groove 2122 in the third direction x, so that the fixture 30 can be assembled into the seat body 212 along the second direction y (as ​ shown), and one end of the fixture 30 abuts against the abutting portion 2121 for positioning.

[0103] At least part of the fixture 30 can extend to the other side of the abutting portion 2121. A locking member 34 is provided on the other side of the abutting portion 2121.

The end structure of the clamping pin 33 is in an inverted conical shape and cooperates with the ball (small steel ball) inside the locking member 34 to achieve clamping and release. By rotating the knob of the locking member 34, the ball inside the locking member 34 can be ejected and retracted. When the ball is ejected, the clamping pin 33 is clamped, and the locking member 34 and the fixture 30 are respectively clamped against both sides of the abutting portion 2121 along the second direction y, so as to quickly assemble the fixture 30 on the seat body 212, that is, the conveying device 20.

[0105] Thus, the fixture 30 is detachably fixed on the seat body 212 through the locking member 34, which can improve the disassembly and assembly efficiency of the fixture 30 on the conveying device 20, so that the testing device 100 provided in the present application can be quickly switched between power adapter production lines with multiple shapes.
