The size of one kind of product to be tested corresponds to the flip structure 400 mounted on the base structure 200 through the mounting structure 300, and the size of the other kind of product to be tested corresponds to the flip structure 400 directly arranged on the base structure 200. Moreover, multiple mounting structures 300 can be designed, and the sizes of the multiple mounting structures 300 in the arrangement direction of the base structure 200, the mounting structure 300 and the flip structure 400 are all different, so that the flip test fixture 10 described above can press and fix multiple kinds of products to be tested, and the multiple kinds of products to be tested correspond to the multiple mounting structures 300 respectively. Therefore, the flip test fixture 10 described above is compatible and can fix products to be tested with different sizes.

[0045] In this embodiment, the product to be tested has an integrated circuit, and the product to be tested can be a chip (IC) in particular. It can be understood that in other embodiments, the product to be tested can also be other products.

[0046] ​In the embodiment, the mounting structure 300 is detachably arranged on the clamp panel 210 by screwing. In this way, it is very convenient to disassemble and assemble.

In this way, it is very convenient to disassemble and assemble. It can be understood that in other embodiments, the turnover structure 400 can also be detachably arranged on the side of the mounting structure 300 away from the clamp panel 210 by clamping, magnetic attraction, or interference fit.

[0048] In the embodiment, the clamp base 220 is detachably arranged on the clamp panel 210. In this way, it is very convenient to disassemble and assemble. In the embodiment, the clamp base 220 is detachably arranged on the clamp panel 210 by screwing. It can be understood that in other embodiments, the clamp base 220 can also be detachably arranged on the clamp panel 210 by clamping, magnetic attraction, or interference fit.

[0049] In the embodiment, as shown in Figure 3 The clamp base 220 is provided with a plurality of limiting portions 222. The plurality of limiting portions 222 correspond one-to-one with a plurality of edge regions of the product to be tested, so as to limit the product to be tested. In this way, it is very convenient to accurately place the product to be tested at a predetermined position. It can be understood that in other embodiments, the limiting portion 222 can be omitted. Specifically, in the embodiment, the product to be tested is square. The limiting portion 222 is four, and the four limiting portions 222 are respectively arranged corresponding to the four corners of the product to be tested.

[0050] In the embodiment, the clamp base 220 is provided with a plurality of floating supports 224 for carrying the product to be tested. Each floating support 224 is arranged at intervals. In this way, not only can the product to be tested be stably carried, but also the risk of scratching the appearance of the product to be tested can be reduced. It can be understood that in other embodiments, the floating support 224 can be omitted. Specifically, in the embodiment, the number of floating supports 224 is the same as the number of limiting portions 222 and is arranged one-to-one.

[0051] In the embodiment, the base structure 200 further comprises a testing assembly 230. The testing assembly 230 has testing sites on the clamp base 220. The pressing cover 410 at the pressing position can make the product to be tested on the clamp base 220 contact with the testing sites. In this way, the turnover testing clamp 10 can have both the function of fixing the product to be tested and the function of testing the product to be tested. It can be understood that in other embodiments, the testing assembly 230 can also be omitted, that is, the turnover testing clamp 10 does not itself integrate the testing assembly 230, at this time, an external testing assembly can be used to test the product to be tested on the turnover testing clamp 10.

[0052] In the embodiment, the testing assembly 230 comprises a circuit board 232 and a probe 234. The circuit board 232 is arranged on the side of the clamp panel 210 away from the clamp base 220. The probe 234 is arranged through the clamp base 220, and both ends of the probe 234 pass through the clamp base 220. One end of the probe 234 is connected with the circuit board 232, and the other end is used to contact with the product to be tested, that is, the testing site comprises the end of the probe 234 away from the circuit board 232.

[0053] In the embodiment, the probe 234 comprises a floating probe. In this way, not only can the product to be tested be accurately contacted with the testing site, but also the risk of scratching the appearance of the product to be tested can be reduced.

[0054] In the embodiment, the turnover testing clamp 10 further comprises a protective cover plate 500. The protective cover plate 500 is arranged on the side of the circuit board 232 away from the clamp panel 210. In this way, the protective cover plate 500 can cover the side of the circuit board 232 away from the probe 234, and when the electrical conduction test of the probe 234 is performed, the test personnel can be prevented from inserting metal electrical conduction parts on the side of the circuit board 232 away from the probe 234.

[0055] In the embodiment, the protective cover plate 500 is detachably arranged on the clamp panel 210, and the circuit board 232 is arranged on the side of the clamp panel 210 away from the clamp base 220. In this way, not only can the circuit board 232 be arranged on the side of the clamp panel 210 away from the clamp base 220 be very convenient, but also the protective cover plate 500 can be arranged on the side of the circuit board 232 away from the clamp panel 210 be very convenient, and the protective cover plate 500 and the circuit board 232 can be easily disassembled on the clamp panel 210. It can be understood that in other embodiments, the circuit board 232 can be fixed on the clamp panel 210 by means of gluing, and the protective cover plate 500 can be fixed on the circuit board 232 by means of gluing. In the embodiment, the protective cover plate 500 is detachably arranged on the clamp panel 210 by means of screwing. It can be understood that in other embodiments, the protective cover plate 500 can also be detachably arranged on the clamp panel 210 by means of clamping, magnetic attraction, and interference fit.

[0056] In the embodiment, the clamp base 220 is detachably arranged on the clamp panel 210, the mounting structure 300 is detachably arranged on the clamp panel 210, the turnover structure 400 is detachably arranged on the side of the mounting structure 300 away from the clamp panel 210, the protective cover plate 500 is detachably arranged on the clamp panel 210, and the circuit board 232 is arranged on the side of the clamp panel 210 away from the clamp base 220, that is, in the embodiment, the turnover test fixture 10 is basically detachable as a whole, so that the turnover test fixture 10 has better convenience in use.

[0057] In the embodiment, the two components detachably connected by screwing have a fixed screw hole and a fixed through hole matched with the fixed screw hole, and the two ends of the screw are matched with the fixed screw hole and the fixed through hole respectively. In the embodiment, the fixed through hole is a countersunk hole. In this way, the screw can be prevented from protruding. In the embodiment, a latch sleeve is arranged in the fixed screw hole. In this way, it is very convenient for repeated disassembly and assembly, and the repeated disassembly and assembly is not easy to damage the components, so that the connection between the components is more reliable. Specifically, in the embodiment, the screw is a standard part such as M3, M4, etc.

[0058] In the embodiment, as shown in Figure 1 and Figure 2 , the mounting structure 300 includes a mounting seat 310. The mounting seat 310 is two, and the two mounting seats 310 are arranged in parallel and spaced apart and are detachably connected with the clamp panel 210 respectively. The turnover structure 400 is detachably arranged on the two mounting seats 310. The use of two spaced apart mounting seats 310 to mount the turnover structure 400 not only facilitates the stable mounting of the turnover structure 400, but also can make the mounting structure 300 occupy less space. It can be understood that in other embodiments, the mounting structure 300 can also include only one mounting seat. The length of the mounting seat matches the length of the turnover structure 400.

[0059] In the embodiment, the turnover structure 400 further includes a base assembly 420 and a turnover assembly 430. The base assembly 420 includes two bases 422, and the two bases 422 are detachably arranged on the two mounting seats 310 respectively. The two ends of the turnover assembly 430 are arranged on the two bases 422 respectively. The gland 410 is arranged on the turnover assembly 430. The turnover assembly 430 can drive the gland 410 to turn over. The use of two spaced apart bases 422 to mount the turnover assembly 430 can make the base assembly 420 occupy less space. It can be understood that in other embodiments, the base assembly 420 can also include only one base, and the length of the base matches the length of the turnover assembly 430.

[0060] In this embodiment, the position of the pressure cap 410 on the flipping assembly 430 is adjustable to adjust the distance between the pressure cap 410 and the clamping panel 210 when in the pressure position. Thus, when the distance adjustment range is large, the distance between the pressure cap 410 and the clamping panel 210 when in the pressure position can be adjusted by adjusting the position of the pressure cap 410 on the flipping assembly 430, thereby enabling the flipping test fixture 10 to apply pressure and fix various test products of different sizes (the various test products have different dimensions in the arrangement direction of the base structure 200, mounting structure 300 and flipping structure 400, that is, the thickness of the various test products is different). When the spacing adjustment range is small (fine adjustment), the spacing between the pressure cap 410 and the fixture panel 210 in the pressure position can be adjusted by adjusting the position of the pressure cap 410 on the flipping assembly 430. This can solve the problem that the pressure cap 410 cannot be flipped to the pressure position due to the small spacing caused by the machining error of the fixture 10, and can also solve the problem that the pressure cap 410 is separated from the product under test when it is flipped to the pressure position due to the large spacing caused by the machining error of the fixture 10.

[0061] In this embodiment, the position of the pressure cap 410 on the flipping assembly 430 is adjustable to adjust the angle between the pressure cap 410 and the clamping panel 210 when in the pressure position. Thus, by adjusting the position of the pressure cap 410 on the flipping assembly 430, the angle between the pressure cap 410 and the clamping panel 210 when in the pressure position can be adjusted, thereby solving the problem of poor fit between the pressure cap 410 and the product under test when in the pressure position due to machining errors in the clamping 10.

[0062] In this embodiment, as Figure 5 As shown, the side of the pressure cap 410 near the fixture panel 210 includes a pressure area 412 and a clearance area 414. In the pressure position, the pressure area 412 abuts against the product to be tested. During the process of the pressure cap 410 flipping to the pressure position, the clearance area 414 can avoid the product to be tested, that is, it does not contact the product to be tested. In this way, the product to be tested can be protected, and the pressure cap 410 can be prevented from damaging the product to be tested.

[0063] In this embodiment, the pressure area 412 is a plane, and the clearance area 414 is an inclined plane relative to the pressure area 412. This makes it very convenient to form a cap 410 having both the pressure area 412 and the clearance area 414. It is understood that in other embodiments, the clearance area 414 may also be a plane parallel to the pressure area 412 and having a height difference.

[0064] In this embodiment, there are two clearance areas 414. A pressure area 412 is located between the two clearance areas 414. The arrangement direction of the two clearance areas 414 intersects the flip axis (i.e., the rotating rod 432) of the pressure cap 410. This provides better protection for the product under test. Specifically, in this embodiment, the arrangement direction of the two clearance areas 414 is orthogonal (perpendicular) to the flip axis of the pressure cap 410. It can be understood that in other embodiments, there may be only one clearance area 414, in which case the clearance area 414 is closer to the flip axis of the pressure cap 410 than the pressure area 412.

[0065] In this embodiment, the pressure cap 410 also has a pick-up / placement position. Figure 5 (As shown in the diagram). The pick-up and drop position is defined by a preset angle of rotation of the pressure cap 410 in the pressure position. In the pick-up and drop position, the product to be tested can be picked up and dropped on the fixture base 220. This makes it very convenient to pick up and drop the product to be tested on the fixture base 220. It can be understood that in other embodiments, when the fixture base 220 is slidably disposed on the fixture panel 210, the pressure cap 410 may not have a pick-up and drop position. In this case, the pressure cap 410 only needs to be rotated by a very small angle (enough to separate the pressure cap 410 from the product to be tested, for example...). Figure 6 (As shown in the figure) By pulling out the clamp base 220, the clamp base 220 can be removed from the interference range of the pressure cover 410. The product to be tested can then be placed or removed on the clamp base 220. After placing or removing the product to be tested, the clamp base 220 can be pushed back to its original position.

[0066] In this embodiment, as Figure 5 As shown, the preset angle is greater than 90°. This makes it easier to place and pick up the product to be tested on the fixture base 220. It is understood that in other embodiments, the preset angle may also be equal to 90°.

[0067] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the flipping assembly 430 includes a rotating rod 432 (the flipping shaft of the pressure cap 410) and a transmission component 434. Transmission components 434 are respectively provided at both ends of the rotating rod 432. The transmission component 434 includes a first transmission rod 4342, a second transmission rod 4344, and a third transmission rod 4346. One end of the first transmission rod 4342 is rotatably connected to the base assembly 420 (the rotating shaft is...). Figure 6 One end of the first transmission rod 4344 is fixedly connected to the end of the rotating rod 432, and the other end is rotatably connected to the middle of the first transmission rod 4342 (the rotating shaft is...). Figure 6(B) It should be noted that in this embodiment, the middle part of the first transmission rod 4342 refers to any part of the first transmission rod 4342 other than the two ends, and does not specifically refer to the midpoint of the first transmission rod 4342. One end of the third transmission rod 4346 passes through the rotating rod 432 and can rotate on the rotating rod 432, and the other end is rotatably connected to the base assembly 420 (the rotating shaft is... Figure 6 (C) in the pressure application position. Figure 1 (As shown in the image), the rotating shaft B between the rotating rod 432, the first transmission rod 4342 and the second transmission rod 4344, and the rotating shaft C between the third transmission rod 4346 and the base assembly 420 are arranged sequentially and located on one side of the rotating shaft A between the first transmission rod 4342 and the base assembly 420. In the pick-up / placement position ( Figure 5 As shown in the diagram, the rotating rod 432 and the pivot B between the first transmission rod 4342 and the second transmission rod 4344 are both located on the other side of the pivot A between the first transmission rod 4342 and the base assembly 420. Thus, by driving the rotating rod 432 to rotate, the pressure cap 410 can be flipped, enabling the pressure cap 410 to switch between a pressing position and a pick-up / drop position, and the flipping angle is greater than 90° during the flipping switching process. It is understood that in other embodiments, the flipping assembly 430 is not limited to the above structure; the flipping assembly 430 can be a flipping assembly on a common flip-cap structure, such as a flipping assembly that cooperates with the flip cap of a rice cooker, or a flipping assembly that cooperates with the lid of a wireless earphone case.

[0068] In this embodiment, the base assembly 420 includes a base 422 detachably connected to the mounting structure 300. There are two bases 422, each corresponding to one of the two transmission components 434. Each base 422 includes two opposing support plates 4222. A first transmission rod 4342 is rotatably connected to the two support plates 4222. Specifically, one end of the first transmission rod 4342 is located between the two support plates 4222 and rotatably passes through them via a shaft pin bolt (rotating shaft A). This facilitates a convenient rotatable connection between the first transmission rod 4342 and the base assembly 420.

[0069] In this embodiment, one end of the second transmission rod 4344 has a U-shaped groove 4344a. The first transmission rod 4342 rotatably passes through the U-shaped groove 4344a. Specifically, the first transmission rod 4342 passes through the U-shaped groove 4344a and is rotatably connected to the U-shaped groove 4344a by a shaft pin bolt (rotating shaft B).

[0070] In the embodiment, the transmission member 434 comprises two third transmission rods 4346. In the transmission member 434, the second transmission rod 4344 is located between the two third transmission rods 4346. The two third transmission rods 4346 of the transmission member 434 are correspondingly arranged with the two support plates 4222 of the base 422, and the third transmission rods 4346 are rotatably arranged outside the support plates 4222. Specifically, the third transmission rods 4346 are located outside the support plates 4222. The third transmission rods 4346 are rotatably arranged on the corresponding support plates 4222 by shaft pin bolts (rotation shaft C). The arrangement of the two third transmission rods 4346 can make the connection between the transmission member 434 and the base 422 more reliable.

[0071] In the embodiment, the second transmission rod 4344 is arranged through the end of the rotating rod 432. In this way, the assembly is very convenient. It can be understood that in other embodiments, the second transmission rod 4344 can also be fixed to the outer wall surface of the end of the rotating rod 432. It should be noted that in the embodiment, the second transmission rod 4344 and the third transmission rod 4346 are both arranged through the rotating rod 432, but the second transmission rod 4344 is fixedly connected with the rotating rod 432, that is, the second transmission rod 4344 rotates synchronously with the rotating rod 432, and the second transmission rod 4344 cannot rotate relative to the rotating rod 432, while the third transmission rod 4346 is rotatably connected with the rotating rod 432, and the third transmission rod 4346 can rotate relative to the rotating rod 432. Specifically, in the embodiment, the second transmission rod 4344 has a first assembly hole, and the second transmission rod 4344 is arranged through the end of the rotating rod 432 through the first assembly hole. The third transmission rod 4346 has a second assembly hole, and the third transmission rod 4346 is arranged through the end of the rotating rod 432 through the second assembly hole. The outer wall surface of the end of the rotating rod 432 comprises two opposite limiting planes and two opposite arc surfaces, each arc surface connecting two limiting planes, that is, the end of the rotating rod 432 is a non-cylindrical rod. The inner wall of the first assembly hole is adapted to the outer wall surface of the end of the rotating rod 432 (that is, the first assembly hole is a non-circular hole), so that the second transmission rod 4344 is fixed to the end of the rotating rod 432 and cannot rotate relative to the rotating rod 432. While the second assembly hole is a circular hole, so that the third transmission rod 4346 can rotate relative to the rotating rod 432.

[0072] In the embodiment, the overturning structure 400 further comprises two handles 440. The two handles 440 are respectively arranged at two ends of the rotating rod 432, and the handles 440 are located outside the transmission members 434. In this way, the rotating rod 432 can be driven to rotate in a manual manner. It can be understood that in other embodiments, a motor or other mechanism can be used to automatically drive the rotating rod 432 to rotate. Specifically, in the embodiment, the handle 440 has a plug-in slot. The inner wall surface of the plug-in slot is matched with the outer wall surface of the end of the rotating rod 432 (i.e., the plug-in slot is a non-circular slot), so that the handle 440 is fixed to the end of the rotating rod 432 and cannot rotate relative to the rotating rod 432.

[0073] In the embodiment, the overturning structure 400 further comprises a locking member. The third transmission rod 4346 is provided with a locking hole 4346a, and the second transmission rod 4344 is provided with a matching hole 4344a matched with the locking hole 4346a. The third transmission rod 4346 and the second transmission rod 4344 can be fixedly connected by the locking member inserted into the locking hole 4346a and the matching hole 4344a, so that the gland 410 remains in the pressing position. In this way, when the product is tested, the rotating rod 432 is not forced (for example, the handle 440 is loosened), and the gland 410 can also be prevented from overturning to cause the gland 410 to deviate from the pressing position. Specifically, in the embodiment, the locking member is a screw. It can be understood that in other embodiments, the locking member, the locking hole 4346a, the matching hole 4344a and the like can be omitted, and at this time, the handle 440 can be used to keep the gland 410 in the pressing position without being loosened.

[0074] In the embodiment, as shown in Figure 1 , the overturning structure 400 further comprises a connecting member 450 and an adjusting member. The two sides of the connecting member 450 are respectively arranged at the first transmission rods 4342 of the two transmission members 434. The gland 410 is arranged at the connecting member 450. In this way, it is very convenient to install the gland 410 on the transmission member 434. It can be understood that in other embodiments, the connecting member 450 can be omitted, and at this time, the gland 410 can be directly installed on the first transmission rods 4342 of the two transmission members 434.

[0075] In the embodiment, the transmission member 434 further comprises an adjusting member. The first transmission rod 4342 is provided with two strip-shaped holes 4342a arranged at intervals in the extending direction of the first transmission rod 4342. In the pressing position, the strip-shaped holes 4342a extend in the arrangement direction of the clamp panel 210 and the mounting structure 300. The connecting member 450 is provided with mounting holes corresponding to the strip-shaped holes 4342a. The connecting member 450 is adjustably mounted on the first transmission rod 4342 by means of the adjusting member threaded through the strip-shaped holes 4342a and the mounting holes. In this way, the distance between the pressing cap 410 and the clamp panel 210 in the pressing position is adjustable (fine adjustment) and the angle between the pressing cap 410 and the clamp panel 210 in the pressing position is adjustable (fine adjustment). Figure 1 For example, in the view shown, the connecting member 450 is moved in the up-down direction so that the mounting holes correspond to the lower ends, the centers or the upper ends of the corresponding strip-shaped holes 4342a, and then the adjusting member is threaded through the strip-shaped holes 4342a and the corresponding mounting holes, so that the distance between the pressing cap 410 and the clamp panel 210 in the pressing position is three-stage adjustable. Figure 1 For example, in the view shown, the connecting member 450 is tilted so that the two mounting holes on the same side of the connecting member 450 correspond to the lower ends, the centers or the upper ends of the corresponding strip-shaped holes 4342a, and then the adjusting member is threaded through the strip-shaped holes 4342a and the corresponding mounting holes, so that the angle between the pressing cap 410 and the clamp panel 210 in the pressing position is three-stage adjustable.

[0076] The embodiment further provides an integrated circuit test system. The integrated circuit test system comprises an integrated circuit tester and the turnover test fixture 10. The integrated circuit tester has a mounting station for mounting the base structure 200. The mounting station has a first positioning member. The clamp panel 210 of the base structure 200 has a second positioning member 240 matched with the first positioning member. The clamp panel 210 is positioned in the mounting station by means of the second positioning member 240. In this way, it is very convenient to transfer the product to be tested on the turnover test fixture 10 to the integrated circuit tester. Specifically, the mounting structure 300 and the turnover structure 400 of the turnover test fixture 10 can be removed from the base structure 200 first, and then the base structure 200 is mounted on the integrated circuit tester. In this way, when the turnover test fixture 10 is a manual test fixture, it is very convenient to convert the manual test (test on the turnover test fixture 10) to automatic test (test on the integrated circuit tester). Specifically, in the embodiment, the integrated circuit tester is a handler. The first positioning member is a guide pin. The second positioning member 240 is a shaft sleeve threaded through the clamp panel 210.
