[0036] The present embodiment discloses a test device, comprising a test module. Please refer to Figure 1 The test module comprises a support 100, a telescopic power piece 200, a pushing piece 300, a floating piece 400 and a board fixing piece 500, the support 100 is provided with first guide grooves 110 and second guide grooves 120 arranged in an oblique array, please refer to Figure 2, the first guide slot 110 is provided with a first guide section 111, a transition section 112 and a second guide section 113 which are sequentially communicated, the angle between the center lines of the first guide section 111 and the second guide section 113 is greater than a right angle and each forms an included angle less than a right angle with the horizontal plane, the telescopic power member 200 is rotatably installed on the support 100, the push member 300 is movably connected with the support 100 through a connecting member 310 installed on the first guide slot 110 and the second guide slot 120, the first end of the push member 300 is rotatably connected with the telescopic power member 200, the second end of the push member 300 is provided with a guide portion 320, the floating member 400 is slidably connected with the push member 300 through the guide portion 320, and a first elastic member 330 such as a spring is connected between the floating member 400 and the push member 300, the board fixing member 500 is rotatably connected with the floating member 400, and a rotary reset member 410 such as a torsion spring is connected between the board fixing member 500 and the floating member 400.
[0037] For example, refer to Figure 2 , the first guide slot 110 and the second guide slot 120 are arrayed, that is, the structures of the first guide slot 110 and the second guide slot 120 are the same, and in the same projection plane, the array direction between the first guide slot 110 and the second guide slot 120 forms a non-zero included angle with the transverse direction and the longitudinal direction, that is, the array is oblique. For the first guide slot 110, the inclination angle of the first guide section 111 is the same as the interface insertion angle of the target workpiece (PCBA to be tested, provided with a vertical interface suitable for SO-DIMM), such as 75°, wherein the inclination angle of the first guide section 111 refers to the included angle between the center line of the first guide section 111 and the horizontal plane, such as shown by R1 in Figure 2 ; the inclination angle of the second guide section 113 refers to the included angle between the center line of the second guide section 113 and the horizontal plane, such as shown by R2 in Figure 2 , and the included angle between the first guide section 111 and the second guide section 113 is shown by R3 in Figure 2R3. It is to be understood that the first guide slot 110 and the second guide slot 120 are of the same structure, i.e. the first guide slot 110 and the second guide slot 120 each have the first guide section 111, the transition section 112 and the second guide section 113. In the initial state, the board fixing member 500, the floating member 400 and the pushing member 300 are linearly distributed, the test board is installed on the board fixing member 500, and the included angle between the test board and the horizontal plane is adapted to the interface insertion angle of the target workpiece. When testing is required, the pushing member 300 is driven by the telescopic driving member, the connecting member 310 of the pushing member 300 moves in the first guide section 111 of the first guide slot 110 and the second guide slot 120, so that the pushing member 300 pushes the test board to insert into the interface of the target workpiece through the floating member 400 and the board fixing member 500. The number of the floating member 400 can be one or more, each floating member 400 is connected to one board fixing member 500, one board fixing member 500 can install one test board, so that a plurality of floating members 400 can install a plurality of test boards.
[0038] Please refer to Figure 2 and Figure 3 When the connecting member 310 moves to the position of the transition section 112, the test board is inserted to the predetermined depth of the interface of the target workpiece, at this time, the pushing member 300 rotates under the guidance of the two transition sections 112, for example Figure 3The midpoint B rotates around the point A, the pushing piece 300 continues to apply a pushing force to the floating piece 400 and the board fixing piece 500, and since the test board has been inserted into the target workpiece interface to a predetermined depth, the test board rotates at a fulcrum in the target workpiece interface (this is the inherent structure of the interface of the target workpiece, which is not described in the embodiment), and changes from an inclined angle state to a right angle state, and the board fixing piece 500 and the floating piece 400 are rotationally connected, and the board fixing piece 500 can rotate relative to the floating piece 400 to change the angle of the force between the floating piece 400 and the board fixing piece 500. Then, the pushing piece 300 continues to push the floating piece 400 and the board fixing piece 500 under the action of the second guide section 113, so that the test board performs a two-stage movement, thereby pushing the test board to be inserted into the target workpiece interface to a predetermined depth. It is worth mentioning that the flexible connection between the pushing piece 300 and the floating piece 400 is achieved by the first elastic piece 330, and the flexible connection between the floating piece 400 and the board fixing piece 500 is achieved by the rotationally connected and rotationally reset spring, so that the flexible connection between the pushing piece 300, the floating piece 400 and the board fixing piece 500 can be achieved, the board fixing piece 500 can rotate relative to the pushing piece 300 and the floating piece 400, and hard contact between the test board installed on the board fixing piece 500 and the interface of the target workpiece can be avoided, thereby reducing the test damage to the target workpiece interface. The second guide section 113 forms an included angle less than a right angle with the horizontal plane, which can guide the pushing piece 300 to move in an inclined direction, thereby applying a longitudinal pushing force to the test board, so that the test board is inserted into the target workpiece interface to a predetermined depth during the two-stage movement.
[0039] Therefore, in use, the test board is installed on the board fixing piece 500, the angle of the first guide section 111 is adapted to the interface insertion angle of the target workpiece, the pushing piece 300 drives the test board to be inserted into the target workpiece through the floating piece 400 and the board fixing piece 500 under the driving of the telescopic power piece 200, the flexible connection is adopted between the pushing piece 300 and the floating piece 400 and between the floating piece 400 and the board fixing piece 500, and the pushing piece 300 drives the test board to perform a two-stage movement under the guidance of the transition section 112 and the second guide section 113, so that the test board realizes angle conversion, thereby realizing automatic testing of the target workpiece, which is beneficial to improve the test efficiency and the reliability of the test.
[0040] Please refer to Figure 2 and Figure 3The bracket 100 comprises a first supporting part 101 and a second supporting part 102 connected with each other, the first guide groove 110 and the second guide groove 120 are arranged on the second supporting part 102, the first end of the telescopic power member 200 is rotatably installed on the first supporting part 101, the second end of the telescopic power member 200 is rotatably connected with the first end of the pushing member 300, and the pushing member 300 is located on the second supporting part 102. For example, the telescopic power member 200 is a cylinder, the first end of the telescopic power member 200 is hingedly connected with the first supporting plate through a first bolt, the second end of the telescopic power member 200 is hingedly connected with the pushing member 300 through a second bolt, so that flexible connections are formed among the pushing member 300, the telescopic power member 200 and the bracket 100, and when the test board card needs to be converted in angle, the telescopic power member 200 can move relative to the bracket 100, thereby reducing the stress among the telescopic power member 200, the bracket 100 and the pushing member 300.
[0041] Please refer to Figure 1 The first guide groove 110 comprises a first sub-groove 114 and a second sub-groove 115 arranged on opposite sides of the bracket 100, and the pushing member 300 is installed in the region between the first sub-groove 114 and the second sub-groove 115. Correspondingly, the opposite sides of the pushing member 300 are provided with a first sub-connection member 311 and a second sub-connection member 312, the first sub-connection member 311 is inserted into the first sub-groove 114, and the second sub-connection member 312 is inserted into the second sub-groove 115, so that the opposite sides of the pushing member 300 are balanced in force and can move along the first guide groove 110. The structure of the second guide groove 120 is the same as that of the first guide groove 110, that is, the second guide groove 120 is also provided with the first sub-groove 114 and the second sub-groove 115, and the first guide groove 110 and the second guide groove 120 cooperate to balance the force of the pushing member 300 in the longitudinal direction and the horizontal direction. Compared with the design scheme of a single guide groove, the double-guide-groove structure design of the embodiment can avoid the rotation of the pushing member 300 around the connection member 310 during the straight-line movement of the pushing member 300 in the first guide section 111 and the second guide section 113 due to uneven force.
[0042] In some application examples, please refer to Figure 4 or Figure 5 The guide part 320 is a guide rod or a sleeving hole arranged on the second end of the pushing member 300, and the floating member 400 is movably sleeved on the guide rod or the sleeving hole. It should be understood that when the pushing member 300 is provided with the guide rod, the floating member 400 is provided with the sleeving hole, or when the pushing member 300 is provided with the sleeving hole, the floating member 400 is provided with the guide rod, so that the sleeving hole and the guide rod can be sleeved, thereby realizing the relative sliding between the pushing member 300 and the floating member 400.
[0043] In some application examples, please refer to and , the guiding portion 320 is one of the guiding hole and guiding pin of the pushing member 300, the floating member 400 is provided with the other of the guiding hole and guiding pin, and the floating member 400 and the pushing member 300 are connected through the guiding hole and guiding pin. For example, the pushing member 300 is provided with a guiding hole, and the floating member 400 is provided with a guiding pin, the guiding pin is arranged in the guiding hole and can move in the guiding hole, so that the relative sliding between the pushing member 300 and the floating member 400 can be realized.
[0044] Please refer to Figure 5 and Figure 6 , at least one of the floating member 400 and the board fixing member 500 is provided with a rotation limiting portion 420, which is used for resetting and rotation limiting of the board fixing member 500, so that the board fixing member 500, the floating member 400 and the pushing member 300 are distributed in a straight line. The rotation resetting member 410 applies a continuous resetting elastic force to the board fixing member 500, so that the board fixing member 500 has a relative movement trend with the floating member 400, and the rotation limiting portion 420 can rotationally limit the board fixing member 500, so that the board fixing member 500 can be stationary at a preset angle relative to the floating member 400, so that the board fixing member 500, the floating member 400 and the pushing member 300 can be distributed in a straight line, that is, the angle between the connecting line of the three and the horizontal plane is adapted to the interface insertion angle of the target workpiece.
[0045] In some application examples, please refer to Figure 5 and Figure 6 , one of the floating member 400 and the board fixing member 500 is provided with a rotation connecting portion 510, the rotation connecting portion 510 is provided with a limiting protrusion 520, and the rotation limiting portion 420 is arranged on the rotation path of the limiting protrusion 520.

[0046] In some application examples, please refer to Figure 4 , the other of the floating member 400 and the board fixing member 500 is provided with an empty slot 430, and the rotation limiting portion 420 is arranged in the empty slot 430. The empty slot 430 rotationally avoids at least one of the rotation connecting portion 510 and the limiting protrusion 520, so that the board fixing member 500 and the floating member 400 can relatively rotate. Moreover, the opposite two side walls of the empty slot 430 can support the rotation shaft of the board fixing member 500, so that the installation of the board fixing member 500 is more firm and reliable.
[0047] Please refer toFigure 7 , Figure 7 A schematic view of a target workpiece, which is a PCBA suitable for mounting SO-DIMM modules, is shown in FIG. 1, and is marked as P0. The target workpiece is provided with a plurality of interfaces suitable for SO-DIMM, which are marked as P1 in FIG. 2, and the adjacent sides of the interfaces are provided with different components, which are marked as P2 in FIG. 3, resulting in a limited insertion space of the interfaces. Manual insertion of test board cards is prone to damage the interfaces or the components on the adjacent sides due to uneven insertion force, and the efficiency of manual operation is low. The test module (marked as Z in FIG. 4) described above can accurately insert the test board cards into the interfaces of the target workpiece and convert the angle after the insertion is completed, and the flexible connection between the pushing member 300, the floating member 400 and the board card fixing member 500 of the test module can avoid damage to the interfaces due to excessive insertion force of the test board cards, and is conducive to improving the reliability of the test.
