Description

Technical Field

[0001] This utility model relates to the field of probe card assembly technology, and in particular to a connector replacement device. Background Technology

[0002] In chip testing, the connection between the test platform and the probe card relies on a ZIF (connector) interface. The connector interface typically includes a male and a female connector; the male connector is located on the test platform, and the female connector is located on the probe card.

[0003] Because connector interfaces are used for high-frequency, high-precision chip testing, the pin arrangement and spacing of their female connectors are typically at the micrometer level. Repeated insertion and removal can easily lead to pin deformation or poor disengagement, thus requiring periodic replacement of the female connector. After replacing the female connector, it is generally secured with rivets to ensure the pin connection strength and electrical connection stability. Currently, some manufacturers use manual hammering to secure the rivets, which can easily impact the probes or cause localized stress concentration, leading to probe breakage or damage to internal circuitry. Furthermore, the rivets should be installed with even force to avoid localized deformation of the probe. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a connector replacement device to solve the problem of easily damaging the probe card when replacing the female connector.

[0005] This utility model provides a connector replacement device, comprising:

[0006] frame;

[0007] The support assembly includes a pad disposed on the frame, the pad having a first surface and the first surface having at least two support protrusions;

[0008] The mounting assembly includes an elastic structure and a pressure head. The pressure head is slidably mounted on the frame via the elastic structure. The pressure head has a second surface opposite to the first surface, and the second surface has at least two pressure holes. The orthographic projection of the pressure holes along the moving direction of the pressure head covers the corresponding support protrusion. When the pressure head is subjected to external force, it moves closer to or further away from the first surface.

[0009] Based on the connector replacement device described above, when replacing the female connector, the probe card pre-installed with the new female connector is first placed on the support assembly, with the front of the partial replacement area of ​​the probe card facing the first surface, so that the support protrusion presses against the rivet. Then, a rivet sleeve is placed at the corresponding position of the partial replacement area, and then force is applied to the pressure head, so that the second surface moves towards the partial replacement area while pressing against the rivet sleeve through the pressure hole, causing the rivet to deform. The rivet sleeve and the rivet are tightly connected, thereby completing the replacement of the female connector. That is, the support protrusion presses against one end of the rivet, while the pressure hole presses against the other end of the rivet. Thus, during the installation of the rivet, force is applied almost only to the rivet, minimizing the impact on other areas of the probe card, thereby avoiding impact or local pressure concentration on the probe card.

[0010] In one embodiment of the connector replacement device described above, at least two positioning protrusions are further provided on the first surface.

[0011] Furthermore, based on the positioning protrusion, the rivet position on the probe card can be quickly located, thereby shortening the total replacement time of the connector female and improving replacement efficiency.

[0012] In one embodiment of the connector replacement device described above, the pad is detachably connected to the frame.

[0013] Furthermore, based on the removable pad design, different sizes of connector females can be adapted by replacing the pads with different sizes.

[0014] In one embodiment of the connector replacement device described above, the support assembly further includes a support block having a limiting surface located on the outside of the component to be replaced, and the limiting surface intersecting with the support surface of the support block.

[0015] Furthermore, the design based on the limiting surface improves the stability of the probe card placement and prevents the probe card from moving when changing connectors.

[0016] In one embodiment of the connector replacement device described above, the support assembly further includes an adjustment structure, the support block is connected to the frame via the adjustment structure, and the adjustment structure is used to move the support block in a horizontal and / or vertical direction.

[0017] Furthermore, based on the setting of the adjustment structure, the horizontal and vertical positions of the support blocks can be adjusted to adapt to different support requirements.

[0018] In one embodiment of the connector replacement device described above, the adjustment structure includes a connecting frame, an adjusting rod, and a slider, wherein:

[0019] The frame has a limiting groove to accommodate the sliding of the slider, the connecting frame is placed on the frame and connected to the support block, and has a passage hole for the adjusting rod to pass through;

[0020] The slider has a threaded through hole. The adjusting rod passes through the through hole and the threaded through hole in sequence and is threadedly connected to the slider. The adjusting rod has a locking end, which is used to press against the connecting frame so that the connecting frame presses against the machine frame.

[0021] In one embodiment of the connector replacement device described above, the connector frame is provided with a base, and the support block is slidably disposed on the base along the moving direction of the pressure head.

[0022] In one embodiment of the connector replacement device described above, the support assembly further includes at least one push rod disposed on one side of the frame.

[0023] In one embodiment of the connector replacement device described above, the top rod includes a base and a rod body, the rod body being threadedly connected to the base.

[0024] In one embodiment of the connector replacement device described above, the elastic structure includes a guide seat, a guide rod, and an elastic element, wherein:

[0025] The guide seat is mounted on the frame, the guide rod slides through the guide seat and is connected to the pressure head, and the elastic element is sleeved on the outside of the guide rod and connected to the guide seat and the guide rod respectively.

[0026] The above-described one or more embodiments of this utility model have at least one or more of the following beneficial effects:

[0027] When replacing the female connector, first place the probe card pre-installed with the new female connector on the support assembly, with the front of the replacement area of ​​the probe card facing the first surface, so that the support protrusion presses against the rivet. Then, place the rivet sleeve at the corresponding position of the replacement area, and then apply force to the pressure head, so that the second surface moves towards the replacement area while pressing against the rivet sleeve through the pressure hole, causing the rivet to deform. The rivet sleeve and the rivet are tightly engaged, thus completing the replacement of the female connector. That is, the support protrusion presses against one end of the rivet, while the pressure hole presses against the other end of the rivet. Therefore, during the installation of the rivet, force is applied almost only to the rivet, minimizing the impact on other areas of the probe card, thereby avoiding impact or local pressure concentration on the probe card.

[0038] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] Currently, some manufacturers use manual hammering to fix the rivets when replacing the female connector of the probe card. This can easily cause impact to the probe card or cause local stress concentration, leading to probe breakage or damage to the internal circuitry.

[0040] Therefore, this application creatively proposes a connector replacement device, which includes a frame, a support assembly, and a mounting assembly. When replacing the female connector, a probe card pre-installed with a new female connector is first placed on the support assembly, with the front of the partial replacement area of ​​the probe card facing the first surface, so that the support protrusion presses against the rivet. Then, a rivet sleeve is placed at the corresponding position of the partial replacement area, and then force is applied to the pressure head, so that the second surface moves towards the partial replacement area while pressing against the rivet sleeve through the pressure hole, causing the rivet to deform. The rivet sleeve and the rivet are tightly engaged, thereby completing the replacement of the female connector. That is, the support protrusion presses against one end of the rivet, while the pressure hole presses against the other end of the rivet, so that during the installation of the rivet, force is applied almost only to the rivet, minimizing the impact on other areas of the probe card, thereby avoiding impact or local pressure concentration on the probe card.

[0041] The present invention will be specifically described below through specific embodiments.

[0042] Reference Figures 1 to 6 As shown, this application embodiment provides a connector replacement device, which includes a frame 1, a support component 2, and a mounting component 3. The support component 2 includes a pad 21 disposed on the frame 1. The pad 21 has a first surface and at least two support protrusions 211 on the first surface. The mounting component 3 includes an elastic structure 31 and a pressure head 32. The pressure head 32 is slidably disposed on the frame 1 through the elastic structure 31. The pressure head 32 has a second surface opposite to the first surface and at least two pressure holes 322. The orthographic projection of the pressure holes 322 along the moving direction of the pressure head 32 covers the corresponding support protrusions 211. When the pressure head 32 is subjected to external force, it moves closer to or away from the first surface.

[0043] The component that the connector replacement device operates on is the replacement part. In this embodiment, the replacement part is a probe card, but of course, the replacement part can also be other electronic components with female heads.

[0044] It should be noted that the first side typically supports the portion of the connector female that needs to be replaced. The connector female on the probe card generally consists of multiple females arranged in a certain pattern. During use, some or all of the females may be used. Therefore, when replacing the connector female, some or all of it may need to be replaced. The portion of the connector female that needs to be replaced is called the partial replacement area. Furthermore, if the entire connector female needs to be replaced, the connector female can be divided into multiple partial replacement areas, and each partial replacement area can be riveted separately.

[0045] Understandably, the number and distribution of the support protrusions 211 are primarily set based on the number and distribution of the rivet holes on the probe card. The number and distribution of the pressure holes 322 follow a similar pattern to the distribution of the support protrusions 211. That is, the support protrusions 211 and / or pressure holes 322 are set based on the number and distribution of the rivet holes in the local replacement area. Furthermore, the shape of the support protrusions 211 can be any regular or irregular shape, such as cylindrical or polygonal, as long as it provides stable support for the rivets.

[0046] Specifically, when replacing the female connector, the replacement part pre-installed with the new female connector is first placed on the support assembly 2, with the front of the partial replacement area of ​​the replacement part facing the first surface, so that the support protrusion 211 presses against the rivet. Then, the rivet sleeve is placed at the corresponding position of the partial replacement area, and then force is applied to the pressure head 32, so that the second surface moves towards pressing against the partial replacement area while pressing against the rivet sleeve through the pressure hole 322, causing the rivet to deform. The rivet sleeve and the rivet are tightly connected, thereby completing the replacement of the female connector. That is, the support protrusion 211 presses against one end of the rivet, while the pressure hole 322 presses against the other end of the rivet. Thus, during the installation of the rivet, force is applied almost only to the rivet, minimizing the impact on other areas of the probe card, thereby avoiding impact or local pressure concentration on the probe card.

[0047] In some embodiments, refer to Figure 2 and Figure 3 As shown, at least two positioning protrusions 212 are also provided on the first surface. By setting at least two positioning protrusions 212, the position of the partial replacement area can be quickly located, so that the pre-installed rivets in the partial replacement area can quickly correspond to the support protrusions 211 on the first surface, thereby shortening the overall time for replacing the connector female head and improving the replacement efficiency.

[0048] In some embodiments, the pad 21 is detachably connected to the frame 1. The shape of the pad 21 can be a regular shape such as a square or a cylinder, or any other irregular shape, as long as it meets the requirement of stably supporting the local replacement area.

[0049] It is understandable that the detachable connection between the pad 21 and the frame 1 can include threaded connection, snap-fit, plug-in connection, etc., as long as it allows for quick assembly and disassembly of the pad 21 and the frame 1. In this embodiment, the connection between the pad 21 and the frame 1 is a plug-in connection, that is, a plug-in post is provided on the frame 1, and a plug-in hole is provided on the pad 21. In use, the plug-in hole is directly engaged with the plug-in post. The detachable design of the pad 21 allows for the selection of appropriate pads 21 when installing different connector females, i.e., the installation of pads 21 with different numbers and distribution positions, thereby improving the adaptability of the replacement device.

[0050] In addition, in some embodiments, the height of the pad 21 relative to the support plane (such as a desktop) of the probe card relative to the frame 1 can be adjusted by changing the thickness of the pad 21 or by adding a block structure between the pad 21 and the frame 1, thereby reducing the impact of desktop clutter on the installation of the probe card.

[0051] In some embodiments, refer to Figure 4 As shown, the support assembly 2 also includes a support block 22, which has a limiting surface 221 located on the outside of the component to be replaced, and the limiting surface 221 intersects with the support surface of the support block 22. In this embodiment, the limiting surface 221 is perpendicular to the support surface of the support block 22, thereby better limiting the probe card.

[0052] The support block 22 can be a regular shape such as a quadrangular prism or a pentagonal prism, or any other irregular shape, as long as it provides stable support for the part to be replaced. In this embodiment, the support block 22 is generally quadrangular prism shaped, the top of the support block 22 is used to support the part to be replaced, and the top of the support block 22 extends to a stop portion, with the limiting surface 221 located on the stop portion.

[0053] Specifically, the support surface on the support block 22 can support the replacement part, while the limiting surface 221 can restrict the replacement part from sliding in the horizontal direction, ensuring the stability of the replacement part when replacing the connector.

[0054] In some embodiments, refer to Figure 1 and Figure 4 As shown, the support assembly 2 also includes an adjustment structure 23. The support block 22 is connected to the frame 1 through the adjustment structure, and the adjustment structure 23 is used to move the support block 22 in the horizontal and / or vertical directions.

[0055] For example, the adjustment structure 23 includes two linear drive components, such as cylinders or electric cylinders. The support block 22 is connected to the drive end of one of the linear drive components, and the fixed end of the linear drive component is connected to the drive end of the other linear drive component. In this embodiment, the support block 22 is arranged opposite to the pad block 21 along a certain horizontal direction. By adjusting the arrangement of the adjustment structure 23, the distance between the support block 22 and the pad block 21 can be adjusted to adapt to support replacement parts of different sizes.

[0056] Reference is provided as an example, not a limitation. Figure 1 and Figure 5As shown, the adjustment structure 23 includes a connecting frame 231, an adjusting rod 232, and a slider 233. The frame 1 has a limiting groove to accommodate the sliding of the slider 233. The connecting frame 231 is placed on the frame 1 and connected to the support block 22, and has a passage hole for the adjusting rod 232 to pass through. The slider 233 has a threaded through hole. The adjusting rod 232 passes through the passage hole and the threaded through hole in sequence and is threadedly connected to the slider 233. The adjusting rod 232 has a locking end 2321, which is used to press against the connecting frame 231 so that the connecting frame 231 presses against the frame 1.

[0057] In this embodiment, in order to improve the assembly efficiency of the device, the frame 1 is divided into two parts: a base 11 and an extension frame 12, which are fixed to the base 11 with bolts, and the limiting slide groove 121 is provided on the extension frame 12.

[0058] Specifically, when adjusting the horizontal distance between the support block 22 and the pad block 21, first loosen the adjusting rod 232 so that the locking end 2321 is separated from the connecting frame 231. Then move the connecting frame 231 so that the connecting frame 231 slides relative to the extension frame 12 through the slider 233, thereby driving the support block 22 to move, thereby changing the horizontal distance between the support block 22 and the pad block 21. After the distance adjustment is completed, tighten the adjusting rod 232 again so that the locking end 2321 presses against the connecting frame 231, thereby pressing the connecting frame 231 against the frame 1 (i.e., the extension frame 12).

[0059] Furthermore, in some embodiments, reference is made to... Figure 1 and Figure 6 As shown, a base 4 is provided on the connecting frame 231, and a support block 22 is slidably disposed on the base 4 along the moving direction of the pressure head 32. In this embodiment, a guide block that slides with the guide groove is provided on the side of the support block 22, and a threaded through hole is provided on the support block 22, with an abutment rod 41 threadedly connected inside the threaded through hole. When it is necessary to adjust the height of the support block 22, loosen the abutment rod 41, then move the support block 22 to the corresponding position, and then tighten the abutment rod 41 so that the abutment rod 41 presses against the base 4.

[0060] In some embodiments, refer to Figure 1 As shown, the support assembly 2 also includes at least one top rod 24, which is located on one side of the frame 1.

[0061] The position of some bearing surfaces can be flexibly adjusted by setting the top rod 24, so as to adjust the bearing position of the component to be replaced.

[0062] Furthermore, the number and distribution of the top rods 24 can be flexibly adjusted according to actual load-bearing requirements. In this embodiment, there is an even number of top rods 24, which are symmetrically distributed about the extension frame 12, thereby providing balanced support for the parts to be replaced.

[0063] Furthermore, in some embodiments, the top rod 24 includes a base 241 and a rod body 242, with the rod body 242 threadedly connected to the base 241. Through the threaded connection between the rod body 242 and the base 241, the overall height of the top rod 24 can be adjusted step by step, thereby better adjusting the overall levelness of the bearing surface.

[0064] The top of the push rod 24 is equipped with a soft pad to prevent wear on the probe card.

[0065] In some embodiments, refer to Figure 1 As shown, the elastic structure 31 includes a guide seat 311, a guide rod 312, and an elastic element 313. The guide seat 311 is mounted on the frame 1. The guide rod 312 slides through the guide seat 311 and is connected to the pressure head 32. The elastic element 313 is sleeved on the outside of the guide rod 312 and is connected to the guide seat 311 and the guide rod 312 respectively.

[0066] In this embodiment, the elastic element 313 is a cylindrical spring, and for ease of operation, an operating frame 5 is provided on the side of the guide seat 311 and hinged to the guide seat 311. At the same time, an intermediate frame is provided between the operating frame 5 and the guide rod 312, and the intermediate frame is hinged to the guide rod 312 and the operating frame 5 respectively.

[0067] Specifically, when applying pressure to the pressure head 32, the operating frame 5 is first rotated, which in turn moves the connecting frame 231 downward, thereby moving the guide rod 312. Simultaneously, the elastic element 313 is compressed, ensuring smooth movement of the pressure head 32 and preventing it from suddenly moving rapidly due to excessive force, which could impact the probe card. After the rivet installation is complete, simply releasing the operating frame 5 will allow the pressure head 32 to return to its original position following the deformation of the elastic element 313.
