[0073] The following invention provides numerous different embodiments or instances for implementing various features of the provided object. Specific examples of components and arrangements are described below to simplify the invention. Of course, these are merely examples and are not intended to be limiting. Furthermore, element symbols and / or letters may be repeated in various instances. This repetition is for simplicity and clarity and does not in itself indicate a relationship between the various embodiments and / or configurations discussed.

[0074] To enable readers to clearly understand the interrelationships and orientations of the various components, coordinate axes are marked in the attached diagram, namely the first axis A1, the second axis A2, and the third axis A3.

[0075] Please see Figure 1 and Figure 2 . Figure 1 This is a schematic diagram of a test device 10 according to one embodiment of the present invention. Figure 2 This is an exploded view of a test device 10 according to one embodiment of the present invention. In some embodiments, the test device 10 includes a test area module 100, a first direction adjustment module 200, a second direction adjustment module 300, at least one test fixture 400, and a power transmission module 500.

[0076] In some embodiments, the test area module 100 includes a product placement area 110 for placing an electronic product under test, such as a laptop computer. In some embodiments, at least one test fixture 400 is capable of mounting test cables, such as Type-C or USB test cables, and is movable along a third axis A3 via a power transmission module 500 to insert or remove the test cables from the connection holes of the electronic product. In some embodiments, a first direction adjustment module 200 is movable along a second axis A2, and a second direction adjustment module 300 is movable along a first axis A1 to adjust the test fixture 400 so that the test cables are aligned with the connection holes of the electronic product.

[0077] In some implementations, the test device 10 is secured between its components using countersunk head bolts. Compared to countersunk head bolts, countersunk head bolts can more effectively reduce the gap between the screw and the screw hole, further improving the stability and accuracy of the installation.

[0078] Please see Figure 3A , Figure 3A This is a schematic diagram of a test area module 100 according to one embodiment of the present invention. In some embodiments, the test area module 100 includes a plurality of product placement platforms 111, 112, 113 and 114, side plates 120 connecting these product placement platforms, and connecting blocks 130 connecting the side plates 120.

[0079] In some embodiments, the test area module 100 includes four product placement platforms 111, 112, 113, and 114, which can simultaneously test four electronic products to improve the testing efficiency. In some embodiments, a side plate 120 is located on one side of the product placement platforms 111, 112, 113, and 114, specifically on the side of the slot to be tested on the electronic product, serving as a support frame for these product placement platforms and also as a connecting plate for connecting other components.

[0080] Please see Figure 3B , Figure 3BThis is a partial exploded view of a side plate 120 and a connecting block 130 according to one embodiment of the present invention. In some embodiments, the side plate 120 includes a surface 121 connecting the connecting block 130 and a groove 122 located on the surface 121. In some embodiments, the connecting block 130 includes a surface 131 connecting the side plate 120 and a protrusion 132 located on the surface 131. After the connecting block 130 is assembled to the side plate 120, the protrusion 132 will engage with the groove 122, and in the second axial direction A2, the width W1 of the groove 122 is greater than the width W2 of the protrusion 132. In some embodiments, the width W1 is about 0.05 mm greater than the width W2, so that a small gap of about 0.05 mm can be reserved when the protrusion 132 is installed in the groove 122. This design not only ensures the positioning accuracy of the connecting block 130 during installation, but also effectively simplifies the assembly process, reduces the difficulty of adjustment caused by error accumulation, thereby improving the overall assembly efficiency and stability.

[0081] Please see Figure 4A , Figure 4A This is a schematic diagram of the connecting block 130 and the first direction adjustment module 200 according to one embodiment of the present invention. In some embodiments, the first direction adjustment module 200 includes at least one first linear slide rail 210, a first sliding platform 220, a first connector 230 connecting the at least one first linear slide rail 210 and the first sliding platform 220, and a first adjusting bolt 240 connected to the first sliding platform 220. In some embodiments, the first direction adjustment module 200 is connected to the connecting block 130 of the test area module 100 via the first linear slide rail 210. In some embodiments, the first direction adjustment module 200 includes two first linear slide rails 210. In some embodiments, the length of the first linear slide rail 210 is 75 mm. The length of the first linear slide rail 210 can be adjusted according to actual usage needs.

[0082] Please see Figure 4B , Figure 4BThis is a partial exploded view of the connecting block 130 and the first direction adjustment module 200 according to one embodiment of the present invention. In some embodiments, the connecting block 130 includes a surface 133 facing the first direction adjustment module 200 and at least one groove 134 located on the surface 133. In some embodiments, the connecting block 130 has two grooves 134 on the surface 133. After the first direction adjustment module 200 is installed on the connecting block 130, the first linear slide rail 210 is disposed in the groove 134, and in the first axial direction A1, the width W3 of the groove 134 is greater than the width W4 of the first linear slide rail 210. In some embodiments, the width W3 is about 0.05 mm greater than the width W4, so that a small gap of about 0.05 mm can be reserved when the first linear slide rail 210 is installed in the groove 134. This design not only ensures the positioning accuracy of the first linear slide rail 210 during installation, but also effectively simplifies the assembly process, reduces the adjustment difficulty caused by error accumulation, thereby improving the overall assembly efficiency and stability.

[0083] Please see Figure 4C , Figure 4C This is a partial schematic diagram of the connecting block 130 and the first linear slide rail 210 according to one embodiment of this invention. Figure 4C This can be explained more clearly in Figure 4B After the first direction adjustment module 200 is installed on the connecting block 130, the width W3 of the groove 134 is greater than the width W4 of the first linear slide rail 210.

[0084] Please see again Figure 4B In some embodiments, the first sliding platform 220 includes a surface 221 facing the connecting block 130 and two recesses 222 located on the surface 221. In some embodiments, the first orientation adjustment module 200 includes two first connectors 230. After the first orientation adjustment module 200 is mounted on the connecting block 130, the first connectors 230 are disposed in the recesses 222, and in the first axial direction A1, the width of the recesses 222 (not shown in the figure) is greater than the width of the first connectors 230 (not shown in the figure). Specifically, the width of the recesses 222 is approximately 0.05 mm greater than the width of the first connectors 230.

[0085] In some embodiments, after the first direction adjustment module 200 is installed on the connecting block 130, the first sliding platform 220 moves along the second axis A2 on the first linear slide rail 210 (please refer to [reference needed]). Figure 4A The first sliding platform 220 can move relative to the connecting block 130 along the second axis A2 via the first linear slide rail 210 and the first connecting member 230. The use of the first linear slide rail 210 ensures parallelism and stability during movement.

[0086] Please refer to the following as well. Figure 4A and Figure 4B In some embodiments, the first direction adjustment module 200 further includes two first fixing blocks 251, 252 configured to fix the first adjusting bolt 240. The first fixing block 251 is connected to the surface 133 of the connecting block 130, and the first fixing block 252 is connected to the side of the first sliding platform 220.

[0087] In some embodiments, the first adjusting bolt 240 includes a bolt 241 and a nut 242. The bolt 241 is fixed to the connecting block 130 by a first fixing block 251, and the nut 242 is fixed to the first sliding platform 220 by the first fixing block 252. When the bolt 241 is rotated, the nut 242 moves closer to or further away from the bolt 241 according to the direction of rotation, thereby causing the first sliding platform 220 to move along the second axis A2, thereby adjusting the position of the first sliding platform 220. In some embodiments, the first adjusting bolt 240 has a knurled structure. Specifically, the knurled structure is located on the bolt 241 to increase grip during strong operation, facilitating precise adjustment of the position by the user.

[0088] In some implementations, the thread length of bolt 241 is 64 mm. The thread length of bolt 241 can be adjusted according to the connection hole requirements of the electronic product under test.

[0089] Please see Figure 5A and Figure 5B . Figure 5A This is a schematic diagram of a first direction adjustment module 200 and a second direction adjustment module 300 according to one embodiment of the present invention. Figure 5B This is an exploded view of the first direction adjustment module 200 and the second direction adjustment module 300 according to one embodiment of the present invention.

[0090] Please also refer to Figure 5A and Figure 5B In some embodiments, the second direction adjustment module 300 includes a second linear slide rail 310, a second sliding platform 320, at least one second connector 330 connecting the second linear slide rail 310 and the second sliding platform 320, and a second adjustment bolt 340 connected to the second sliding platform 320. In some embodiments, the second direction adjustment module 300 is connected to the first sliding platform 220 via the second linear slide rail 310, thereby connecting to the first direction adjustment module 200. In some embodiments, the length of the second linear slide rail 310 is 150 mm. The length of the second linear slide rail 310 can be adjusted according to actual usage needs.

[0091] Please see Figure 5BIn some embodiments, the first sliding platform 220 includes a surface 223 facing the second direction adjustment module 300, a recessed region 224 located on the surface 223, and two connecting surfaces 2241, 2242 connecting the surface 223 and the recessed region 224. The second linear slide rail 310 is disposed in the recessed region 224 and abuts against the two connecting surfaces 2241, 2242.

[0092] In some embodiments, the second sliding platform 320 includes a surface 321 facing the first direction adjustment module 200 and two recesses 322 located on the surface 321. In some embodiments, the second direction adjustment module 300 includes two second connectors 330. After the second direction adjustment module 300 is mounted on the first direction adjustment module 200, the second connectors 330 are disposed in the recesses 322, and along the second axial direction A2, the width of the recesses 322 (not shown in the figures) is greater than the width of the second connectors 330 (not shown in the figures). Specifically, the width of the recesses 322 is approximately 0.05 mm greater than the width of the second connectors 330.

[0093] In some embodiments, the second sliding platform 320 has at least one opening 324 configured to hold the test fixture 400. In some embodiments, the second sliding platform 320 has four openings 324, corresponding to the product placement platforms 111, 112, 113 and 114 of the test area module 100, respectively.

[0094] In some embodiments, after the second direction adjustment module 300 is mounted on the first direction adjustment module 200, the second sliding platform 320 moves along the first axis A1 on the second linear slide rail 310. The second linear slide rail 310 and the second connecting member 330 allow the second sliding platform 320 to move relative to the first direction adjustment module 200 along the first axis A1. Therefore, the direction of movement of the first sliding platform 220 on the first linear slide rail 210 is perpendicular to the direction of movement of the second sliding platform 320 on the second linear slide rail 310. Using the second linear slide rail 310 ensures parallelism and stability during movement.

[0095] Please refer to the following as well. Figure 5A and Figure 5B In some embodiments, the second direction adjustment module 300 further includes two second fixing blocks 351, 352 configured to fix the second adjusting bolt 340. The second fixing block 351 is connected to the surface 223 of the first sliding platform 220, and the second fixing block 352 is connected to the surface 323 of the second sliding platform 320.

[0096] In some embodiments, the second adjusting bolt 340 includes a bolt 341 and a nut 342. The bolt 341 is fixed to the first sliding platform 220 by a second fixing block 351, and the nut 342 is fixed to the second sliding platform 320 by the second fixing block 352. When the bolt 341 is rotated, the nut 342 moves closer to or further away from the bolt 341 according to the direction of rotation, thereby causing the second sliding platform 320 to move along the first axial direction A1, thereby adjusting the position of the second sliding platform 320. In some embodiments, the second adjusting bolt 340 has a knurled structure. Specifically, the knurled structure is located on the bolt 341 to increase grip during strong operation, facilitating precise adjustment by the user. Figure 5B In the middle, the second fixing block 351 passes through the through hole 325 of the second sliding platform 320 so that the second adjusting bolt 340 is fixed to the surface 323 of the second sliding platform 320.

[0097] In some implementations, the thread length of bolt 341 is 38 mm. The thread length of bolt 341 can be adjusted according to the connection hole requirements of the electronic product under test.

[0098] In some embodiments, the test device 10 further includes a spring 260 connecting the first direction adjustment module 200 and the second direction adjustment module 300, configured to ensure the stability of the adjusted position. After the position is adjusted by the first direction adjustment module 200 and the second direction adjustment module 300, the spring 260 is installed to prevent the slide rail from displacing due to vibration caused by repeated insertion and removal during the test. In this design, the minimum length of the spring 260 must be greater than the distance of the installation position to ensure that the spring 260 is always under stress, thereby maintaining the stability and reliability of the overall system.

[0099] Please see Figures 6A to 6C . Figure 6A This is a schematic diagram of a second direction adjustment module 300, a test fixture 400, and a power transmission module 500 according to one embodiment of this invention. Figure 6B This is a schematic diagram of a second direction adjustment module 300 and a test fixture 400 according to one embodiment of this invention. Figure 6C This is a schematic diagram of a test fixture 400 according to one embodiment of the present invention.

[0100] In some embodiments, the test fixture 400 includes a body 410 and a push plate 420 connected to the body 410. The body 410 is disposed in an opening 324 of the second sliding platform 320, and the push plate 420 is connected to the side of the body 410 away from the first direction adjustment module 200 (please refer to the accompanying document). Figure 2 ).exist Figures 6A to 6C In the middle, only the test fixture 400 located at the bottom of the second sliding platform 320 is displayed.

[0101] In some embodiments, the body 410 includes a test lead placement slot 414 for placing test leads and a positioning element 413 to assist in insertion positioning. In some embodiments, the push plate 420 is made of a magnetic material. In some embodiments, the push plate 420 is made of S45C material to ensure its strength and durability. To prevent rust and meet aesthetic requirements, the surface of the push plate 420 may be treated with a thin layer of paint to improve corrosion resistance and enhance appearance.

[0102] exist Figure 6C In this design, the body 410 of the test fixture 400 includes a surface 411 connecting to the second sliding platform 320 and a set of mounting holes 412 located on the surface 411. To prevent the test fixture 400 from being unable to be accurately installed due to machining errors, this set of mounting holes 412 includes a circular positioning hole 4121 and an elliptical adjustment hole 4122. This design not only effectively compensates for possible errors in the process but also ensures the stable assembly of the test fixture 400, improving the overall installation accuracy and reliability.

[0103] In some embodiments, the power transmission module 500 is located on the side of the test fixture 400 away from the first direction adjustment module 200 (see also [reference needed]). Figure 2 In some embodiments, the power transmission module 500 includes a linear cylinder 510 and an electromagnet 520. The electromagnet 520 is located between the linear cylinder 510 and the test fixture 400.

[0104] Please see Figure 7 and Figure 8 . Figure 7 This is a side view of the second direction adjustment module 300, the test fixture 400, and the power transmission module 500 according to one embodiment of the present invention. Figure 8 This is a side view of a test device 10 according to one embodiment of the present invention.

[0105] In some embodiments, the test fixture 400 can be moved closer to the test area module 100 along the third axis A3 by a linear cylinder 510, and a magnetic force can be generated by energizing an electromagnet 520. When energized, the magnetic force attracts a magnetic push plate 420, causing the test fixture 400 to move away from the test area module 100 along the third axis A3. The appropriate linear cylinder and electromagnet models can be selected based on the experimentally measured insertion and extraction force requirements of the connection holes. This design allows for the simultaneous movement of four test fixtures 400 by a single power transmission module 500, simplifying the overall design and effectively reducing equipment costs.

[0106] In summary, the testing equipment of this invention uses a first-direction adjustment module and a second-direction adjustment module to precisely adjust the position of the test fixture, and a power transmission module to push or pull the test fixture for insertion and removal. The linear slide rails of the first-direction adjustment module and the second-direction adjustment module achieve precise installation through the width difference between themselves and the mounting groove. Therefore, the testing equipment of this invention reduces costs while maintaining high efficiency and reliability, making it suitable for testing scenarios requiring high precision and stability.
