Description

Technical Field

[0001] This application relates to an assembly fixture, and more particularly to an assembly fixture for assembling water-cooled plates. Background Technology

[0002] When installing electronic components such as the Central Processing Unit (CPU) and water-cooling plates, jigs are used for assembly to improve assembly efficiency.

[0003] However, using existing assembly fixtures for assembly is not only complicated, but the CPU is also prone to falling off, and a different fixture is needed to tighten the screws, making it very inconvenient to use.

[0004] Therefore, how to propose an assembly fixture that can solve the above problems is one of the issues that the industry is currently eager to address by investing research and development resources. Summary of the Invention

[0005] Based on this, one objective of this application is to provide an assembly fixture that can solve the above-mentioned problems.

[0006] This application relates to an assembly fixture including a base, a first clamping arm, a second clamping arm, and a drive member. The first clamping arm is slidably connected to the base. The first clamping arm includes a first clamping portion and a second clamping portion. The second clamping arm is slidably connected to the base and includes a third clamping portion and a fourth clamping portion. The drive member engages at least one of the first and second clamping arms. The drive member is configured to drive the first and second clamping arms to move in opposite directions, causing the first and third clamping portions to move towards each other, and causing the second and fourth clamping portions to move towards each other. The first and second clamping arms are configured to slide parallel to each other along an axial direction relative to the base. The third clamping portion is axially located between the first and second clamping portions. The second clamping portion is axially located between the third and fourth clamping portions.

[0007] In some embodiments, the first clamping arm further includes a first engaging portion, and the second clamping arm further includes a second engaging portion. One side of the drive member engages with the first engaging portion. The other side of the drive member engages with the second engaging portion.

[0008] In some embodiments, the assembly fixture further includes a rotating member and a top cover. The rotating member is connected to a drive member. The top cover is fixed to a base. The top cover covers the side of the first and second clamping arms away from the base. The rotating member extends through the top cover and is configured to receive rotational force to move the first and second clamping arms in opposite directions.

[0009] In some embodiments, the assembly fixture further includes an assembly guide hole. The assembly guide hole extends through the base along a through direction and does not perpendicularly overlap with the first clamping arm and the second clamping arm in the through direction.

[0010] In some embodiments, the first clamping arm further includes a plate and an extension. The two ends of the extension are connected to the plate and the first clamping portion, respectively. The plate and the first clamping portion are located on opposite sides of the base.

[0011] In some embodiments, the assembly fixture further includes a top cover. The top cover includes a perforation. A first clamping arm and a second clamping arm are disposed between the top cover and the base. At least one of the first clamping arm and the second clamping arm includes a first visual recognition area and a second visual recognition area. When the first clamping portion and the third clamping portion are separated by a first distance, the perforation exposes the first visual recognition area. When the second clamping portion and the fourth clamping portion are separated by a second distance less than the first distance, the perforation exposes the second visual recognition area.

[0012] In some embodiments, the assembly fixture further includes two limiting plates. The two limiting plates are connected to the base. The two limiting plates are located on opposite sides of at least one of the first clamping arm and the second clamping arm. The two limiting plates protrude from the side of the base near the first clamping portion.

[0013] In some embodiments, the assembly fixture further includes a top cover disposed on a base and a first resilient limiting post configured to engage with the top cover. A first clamping arm includes a limiting hole corresponding to the first resilient limiting post. When the first clamping portion and the third clamping portion are separated by a first distance, the first resilient limiting post is elastically compressed. When the first clamping portion and the third clamping portion are separated by a second distance less than the first distance, the first resilient limiting post elastically recovers and at least partially enters the limiting hole.

[0014] In some embodiments, the assembly fixture further includes a second resilient limiting post. The second resilient limiting post is connected to the base. The second resilient limiting post protrudes from the side of the base near the first clamping portion.

[0015] In summary, because the assembly fixture of this application includes a driving component, it can drive the first clamping arm and the second clamping arm to move in opposite directions to securely and conveniently clamp the central processing unit and the water-cooling plate using each clamping part. Furthermore, the assembly fixture of this application may also include features such as elastic limiting posts and assembly holes. These features enable production line assembly personnel to more conveniently and efficiently install the central processing unit and the water-cooling plate onto the motherboard, thereby improving production line efficiency.

[0030] The following disclosure will now be described more fully with reference to the accompanying drawings and figures, some of which are exemplary embodiments. This application may be implemented in various forms and should not be limited to the embodiments mentioned below. However, these embodiments are provided to aid in a more complete understanding of the contents of this application and to fully convey the scope of the invention to those skilled in the art. The same reference numerals will refer to similar components throughout the document.

[0031] In addition, the illustrations provided in this application are drawn to scale. To maintain the brevity of the specification, the proportions of each component are not listed in detail. However, the proportions and positions of each component should be considered part of the content of this specification.

[0032] Please refer to Figure 1 . Figure 1 A perspective view of an assembly fixture 10, a central processing unit 20, a water-cooled plate 30, and a cooling water tank assembly 40 according to one embodiment of this application is shown. The assembly fixture of the present invention is applicable, for example, to a server.

[0033] In this embodiment, two water-cooled plates 30 are respectively mounted on two central processing units 20. The cooling water tank assembly 40 includes a tank body 42 and water-cooling pipes 44. The water-cooling pipes 44 connect the tank body 42 and the water-cooled plates 30. Obviously, the tank body 42, the two water-cooled plates 30, and the two central processing units 20 connected by the water-cooling pipes 44 are bulky and difficult for one person to grasp and lift. They are not easy to move and assemble without the assistance of tools. The assembly jig 10 is configured to clamp the central processing unit 20 and / or the water-cooled plates 30. The assembly jig 10 can cover the central processing unit 20 and / or the water-cooled plates 30 to prevent damage to the central processing unit 20 and / or the water-cooled plates 30 from collisions during handling and movement. After the assembly fixture 10 clamps the central processing unit 20 and / or the water cooling plate 30, the assembler can hold the water tank body 42 with one hand and the gripping part G of the assembly fixture 10 with the other hand. In this way, one person can easily move the central processing unit 20, the water cooling plate 30 and the cooling water tank assembly 40.

[0034] It should be noted that this application is not intended to limit the hardware that the assembly fixture 10 can hold and fix. For the sake of brevity, the term "electronic component" as used herein may include two central processing units 20, two water-cooled plates 30, a cooling water tank assembly 40, and / or other suitable electronic components.

[0035] The structure of the assembly fixture 10 will be described in detail below.

[0036] Please refer to Figure 2 . Figure 2 An exploded view of an assembly jig 10 according to one embodiment of this application is shown. In this embodiment, the assembly jig 10 includes a first clamping arm 100, a second clamping arm 200, a base 300, a top cover 400, and a drive member 500. The first clamping arm 100 and the second clamping arm 200 are slidably connected to the base 300. More specifically, the base 300 includes one or more sliding grooves 310, and the first clamping arm 100 and the second clamping arm 200 selectively slide relative to the base 300 by partially inserting into the sliding grooves 310. The drive member 500 is connected to the first clamping arm 100 and the second clamping arm 200. The top cover 400 is disposed above the first clamping arm 100 and the second clamping arm 200. More specifically, the top cover 400 covers the side of the first clamping arm 100 and the second clamping arm 200 away from the base 300. The top cover 400 is secured to the base 300 by one or more fasteners (e.g., screws 401).

[0037] Please refer to Figure 3A . Figure 3AA perspective view of a first clamping arm 100 according to an embodiment of this application is shown. In this embodiment, the first clamping arm 100 includes a first clamping portion 110, a second clamping portion 120, a plate body 130, an extension portion 140a, an extension portion 140b, and a first engaging portion 150.

The first clamping portion 110 and the second clamping portion 120 extend in the same direction. The first engaging portion 150 is on the plate body 130. The first engaging portion 150 includes a plurality of serrations. The first engaging portion 150 is located between the first clamping portion 110 and the second clamping portion 120. The first engaging portion 150 is configured to engage the drive member 500. Figure 2 ).

[0038] Please also refer to Figure 2 as well as Figure 3A Extensions 140a and 140b are configured to pass into the sliding groove 310. Plate 130 and the first clamping portion 110 are located on opposite sides of the base 300. Plate 130 and the second clamping portion 120 are located on opposite sides of the base 300.

[0039] Please refer to Figure 3B . Figure 3B A perspective view of a second clamping arm 200 according to an embodiment of this application is shown. The second clamping arm 200 includes a third clamping portion 210, a fourth clamping portion 220, a plate body 230, an extension portion 240a, an extension portion 240b, and a second engaging portion 250. One end of the extension portion 240a is connected to the plate body 230, and the other end is connected to the third clamping portion 210. One end of the extension portion 240b is connected to the plate body 230, and the other end is connected to the fourth clamping portion 220. The third clamping portion 210 and the fourth clamping portion 220 extend in a direction away from the extension portions 240a and 240b, respectively. The third clamping portion 210 and the fourth clamping portion 220 extend in the same direction. The second engaging portion 250 is on the plate body 230. The second engaging portion 250 includes a plurality of serrations. The second engaging portion 250 is located between the third clamping portion 210 and the fourth clamping portion 220. The second engaging portion 250 is configured to engage the drive member 500. Figure 2 ).

[0040] Please also refer to Figure 2 as well as Figure 3BExtensions 240a and 240b are configured to pass into the sliding groove 310. Plate 230 and the third clamping portion 210 are located on opposite sides of the base 300. Plate 230 and the fourth clamping portion 220 are located on opposite sides of the base 300.

[0041] Please refer to Figure 4A . Figure 4A A top view of some components and electronic components of the assembly fixture 10 according to one embodiment of this application is shown. Figure 4A For clarity, phrases such as "in the text" have been omitted. Figure 2 The top cover 400 is shown in the figure. In this embodiment, the drive member 500 can be a transmission gear. One side of the drive member 500 engages with the first engagement portion 150. The other side of the drive member 500 engages with the second engagement portion 250. The first engagement portion 150 and the second engagement portion 250 are located on opposite sides of the drive member 500.

[0042] Please refer to Figure 5A . Figure 5A It shows Figure 4A A bottom view of the assembly fixture 10. In this embodiment, the third clamping portion 210 is located between the first clamping portion 110 and the second clamping portion 120 in the axial x direction.

[0043] The second clamping portion 120 is located between the third clamping portion 210 and the fourth clamping portion 220 in the x-axis direction. The first clamping portion 110 is directly opposite the third clamping portion 210 in the x-axis direction. The second clamping portion 120 is directly opposite the fourth clamping portion 220 in the x-axis direction.

[0044] Please also refer to Figure 4A and Figure 5A In some embodiments, the first clamping arm 100 and the second clamping arm 200 are slidably engaged with the base 300 parallel to each other along the axial direction x. In other words, the first clamping arm 100 and the second clamping arm 200 are configured to slide parallel to each other relative to the base 300 along the axial direction x. The plate body 130 includes a protrusion A and a protrusion B. Protrusions A and B extend protrudingly along the axial direction y. The plate body 230 includes a protrusion C and a protrusion D. Protrusions C and D extend protrudingly along the axial direction y. The first clamping portion 110, the second clamping portion 120, the third clamping portion 210, and the fourth clamping portion 220 are perpendicularly overlapped in the axial direction z with the protrusions A, B, C, and D of the first clamping arm 100, respectively. The protrusion B is located between the protrusions C and D in the axial direction x. The protruding part C is located between the protruding parts A and B in the axial direction x.

[0045] The following will explain in detail the operation of the assembly fixture 10.

[0046] Force can be applied to assembly jig 10 in the following ways. Please also refer to... Figure 4A as well as Figure 4B . Figure 4B A top view of some components and electronic components of an assembly fixture 10 according to another embodiment of this application is shown. Figure 4B For clarity, the following has been omitted. Figure 2 The top cover 400 is shown in the figure. In this embodiment, the assembly fixture 10 also includes a rotating member 502. The rotating member 502 is connected to the drive member 500. The rotating member 502 is configured to receive a rotational force to rotate the drive member 500. That is, the assembler can apply force to the rotating member 502 to cause the drive member 500 to slide the first clamping arm 100 and the second clamping arm 200 relative to the base 300. In some embodiments, the first clamping arm 100 and the second clamping arm 200 may each include a force-applying hole 102 and a force-applying hole 202. The force-applying hole 102 and the force-applying hole 202 are configured to receive a tensile force to slide the first clamping arm 100 and the second clamping arm 200 relative to the base 300. Since the first clamping arm 100 and the second clamping arm 200 are located on opposite sides of the driving member 500, when force is applied to any one of the rotating member 502, the force application hole 102 and the force application hole 202, the first clamping arm 100 and the second clamping arm 200 move in opposite directions along the axial direction x.

[0047] Please continue to refer to this. Figure 4A as well as Figure 4B In some embodiments, the first clamping arm 100 and the second clamping arm 200 can be moved in opposite directions along the axial x by applying a rotational force F1 to the rotating member 502. More specifically, the first clamping arm 100 moves in the direction of arrow A1 along the axial x, and the second clamping arm 200 moves in the direction of arrow A2 along the axial x. Protrusion A approaches protrusion C. Protrusion B approaches protrusion D.

[0048] Please refer to Figure 5A and Figure 5B . Figure 5B It shows Figure 4B A bottom view of the assembly fixture 10. In some embodiments, such as... Figure 5AAs shown, there is a distance D1 between the first clamping portion 110 and the third clamping portion 210, and a distance D2 between the second clamping portion 120 and the fourth clamping portion 220. After applying a rotational force F1 to the rotating member 502, the first clamping portion 110 and the second clamping portion 120 move in the direction of arrow A1. The third clamping portion 210 and the fourth clamping portion 220 move in the direction of arrow A2. In other words, the first clamping portion 110 and the third clamping portion 210 move towards each other in the axial x-axis. The second clamping portion 120 and the fourth clamping portion 220 move towards each other in the axial x-axis. Figure 5B As shown, after the first clamping part 110 and the third clamping part 210 move towards each other in the x-axis, there is a distance D3 between them. After the second clamping part 120 and the fourth clamping part 220 move towards each other in the x-axis, there is a distance D4 between them. Distance D1 is greater than distance D3. Distance D2 is greater than distance D4.

[0049] In some embodiments, distances D3 and D4 can be set to appropriate widths for clamping the electronic components, depending on their dimensions. For example, if the two water-cooling plates 30 being clamped are of the same size, then distance D3 is equal to distance D4. It should be noted that this application does not intend to limit the specific widths of distances D3 and D4.

[0050] Accordingly, through the transmission of the drive component 500, each clamping part can move towards the other to conveniently and securely clamp the electronic components, thereby improving the efficiency of the production line.

[0051] In some embodiments of this application, the drive element 500 is a transmission gear with serrated edges. In some alternative embodiments, the drive element 500 can be replaced with one or more other components according to the operator's needs, such as a stepper motor, drive shaft, drive belt, a transmission gear set formed by multiple gears, or other components that can simultaneously drive the first clamping arm 100 and the second clamping arm 200. It should be noted that in the embodiment where the drive element 500 is a transmission gear, since the transmission gear meshes with both the first clamping arm 100 and the second clamping arm 200 simultaneously, when repeatedly using the assembly fixture 10 to clamp multiple sets of electronic components, each clamping can accurately fix the electronic components in the same position relative to the base 300. That is to say, in addition to being simple in construction and convenient for maintenance, the transmission gear can also make subsequent alignment and installation more intuitive and convenient for assembly personnel. In some embodiments, the rotating element 502 can be automatically controlled and clamped by a robotic arm and a server and artificial intelligence that control the robotic arm.

[0052] It should be noted that the engagement of the drive member 500 with the clamping arm (e.g., the first clamping arm 100 and / or the second clamping arm 200) may include an embodiment in which the drive member 500 directly engages with the clamping arm, or an embodiment in which the drive member 500 indirectly engages with the clamping arm through one or more gears.

[0053] Please also refer to Figure 4A and Figure 6 . Figure 6 A top view of the top cover 400 of an assembly jig 10 according to one embodiment of this application is shown. In some embodiments, the top cover 400 includes a variety of through holes with different functions. For example, the top cover 400 may include a plurality of through holes 402 for fastening fasteners, configured to allow fasteners (e.g., screws 401) to secure the top cover 400 to the base 300 along the axial direction z. For example, the top cover 400 may include one or two through holes 404 corresponding to force application holes 102 and / or force application holes 202, configured to allow an assembler to pass their fingers through the through holes 404 to apply a pulling force to the force application holes 102 and / or force application holes 202 along the axial direction x. For example, the top cover 400 may include a through hole 406 configured to allow a rotating member 502 to protrude along the axial direction z. The through hole 406 may fix the relative position of the rotating member 502 to the top cover 400. More specifically, the rotating member 502 rotates relative to the upper cover 400 in the perforation 406, but the rotating member 502 does not move relative to the perforation 406.

[0054] Please continue to refer to this. Figure 4A and Figure 6 In some embodiments, the assembly fixture 10 further includes an assembly guide hole 12. The assembly guide hole 12 extends along the axial direction z through the top cover 400 and the base 300. In the axial direction z, the assembly guide hole 12 does not perpendicularly overlap with the first clamping arm 100 and the second clamping arm 200. When the first clamping arm 100 and the second clamping arm 200 clamp and secure the electronic component, the assembly guide hole 12 is configured to perpendicularly overlap with an assembly hole (not shown) on the electronic component in the axial direction z. For example, when the electronic component is clamped by the assembly fixture 10 and placed onto the motherboard, in some embodiments, because the assembly guide hole 12 perpendicularly overlaps with the assembly hole on the electronic component in the axial direction z, the assembler can directly insert fasteners (e.g., screws) through the assembly guide hole 12 into the assembly hole to secure the electronic component to the motherboard without needing to remove the assembly fixture 10 and replace it with another fixture for fastening. In addition, by assembling the guide hole 12, it is easier to use tools such as screwdrivers to fasten the fasteners, and it can also avoid damaging the motherboard below during the fastening process.

[0055] When performing repetitive assembly tasks on a production line, a function that indicates that the assembly fixture is in place (clamped in position) can improve the efficiency of assembly workers. The following will explain in detail the structure and function of the assembly fixture 10 that indicates that the assembly is in place.

[0056] Please also refer to Figure 4A , Figure 5A as well as Figure 6 In some embodiments, the top cover 400 includes a perforation 408 (in... Figure 5A (Indicated by dashed lines). The first clamping arm 100 includes a first visual recognition area V1 and a second visual recognition area V2. The perforation 408 exposes either the first visual recognition area V1 or the second visual recognition area V2 depending on the position of the first clamping arm 100 and the second clamping arm 200 relative to the top cover 400. The first visual recognition area V1 and the second visual recognition area V2 have different colors, patterns, light emission methods, and other visual differences to visually assist production line assembly personnel in assembly. For example, the first visual recognition area V1 is red, while the second visual recognition area V2 is blue. Figure 4A and Figure 4B In the diagram, the first visual recognition area V1 and the second visual recognition area V2 are marked by different patterns of dots. In some embodiments, when there is a first distance D1 between the first clamping part 110 and the third clamping part 210, the perforation 408 of the upper cover 400 (in...) Figure 4A (Represented by dashed lines) Exposes the first visual recognition area V1.

[0057] Please also refer to Figure 4B , Figure 5B as well as Figure 6 In this embodiment, the first clamping arm 100 and the second clamping arm 200 slide in opposite directions, causing the first clamping portion 110 and the third clamping portion 210 to slide towards each other, forming a third distance D3. When the first clamping portion 110 and the third clamping portion 210 have a third distance D3, the through hole 408 of the upper cover 400 (in Figure 4B (Indicated by dashed lines) The second visual recognition area V2 is exposed. Based on this, the assembly personnel can determine the distance between the clamping parts through the first visual recognition area V1 and the second visual recognition area V2 in the visual perforation 408. In other words, they can determine whether the electronic component has been clamped.

[0058] In some embodiments, when there is a maximum distance (e.g., a first distance D1) between the first clamping portion 110 and the third clamping portion 210, the perforation 408 exposes only the first visual recognition area V1. When the first clamping portion 110 and the third clamping portion 210 slide toward each other, the perforation 408 exposes a portion of the first visual recognition area V1 and a portion of the second visual recognition area V2. When there is a distance sufficient to clamp the electronic component (e.g., a third distance D3) between the first clamping portion 110 and the third clamping portion 210, the perforation 408 exposes only the second visual recognition area V2.

[0059] In some embodiments, both the first clamping arm 100 and the second clamping arm 200 include a first visual recognition region V1 and a second visual recognition region V2, and the top cover 400 includes two through holes 408. In some embodiments, the second visual recognition region V2 has a dimension approximately the same as that of the through holes 408 in the axial z direction.

[0060] It should be noted that the position and size of the first visual recognition area V1 and the second visual recognition area V2 may vary depending on the electronic components to be clamped and assembled. This application is not intended to limit the specific position and shape of the first visual recognition area V1 and the second visual recognition area V2.

[0061] Please also refer to Figure 2 as well as Figure 6 In some embodiments, the assembly fixture 10 further includes first resilient limiting posts 610a and 610b. The upper cover 400 includes through holes 410a and 410b. The first resilient limiting posts 610a and 610b are detachably connected to the through holes 410a and 410b of the upper cover 400, respectively. The first resilient limiting post 610a is configured to fix the relative position of the upper cover 400 and the first clamping arm 100. The first resilient limiting post 610b is configured to fix the relative position of the upper cover 400 and the second clamping arm 200. The first clamping arm 100 includes a limiting hole 160 corresponding to the first resilient limiting post 610a. The second clamping arm 200 includes a limiting hole 260 corresponding to the first resilient limiting post 610b. When the perforation 410a is perpendicularly overlapped with the limiting hole 160 in the axial z direction, the first elastic limiting post 610a can at least partially enter the limiting hole 160 to fix the relative position of the first clamping arm 100 and the upper cover 400. Similarly, when the perforation 410b is perpendicularly overlapped with the limiting hole 260 in the axial z direction, the first elastic limiting post 610b can at least partially enter the limiting hole 260 to fix the relative position of the second clamping arm 200 and the upper cover 400. In some embodiments, a force can be applied along the axial z direction to pull the first elastic limiting posts 610a and 610b out of the perforations 410a and 410b, respectively.

[0062] Please also refer to Figure 4A , Figure 5A as well as Figure 6In some embodiments, when there is a first distance D1 between the first clamping portion 110 and the third clamping portion 210, the first elastic limiting post 610a does not perpendicularly overlap with the limiting hole 160 in the axial z direction. One end of the first elastic limiting post 610a is connected in the through hole 410a, and the other end presses against the plate 130 in the axial z direction, thus elastically compressing it. In some embodiments, when there is a first distance D2 between the second clamping portion 120 and the fourth clamping portion 220, the first elastic limiting post 610b does not perpendicularly overlap with the limiting hole 260 in the axial z direction. One end of the first elastic limiting post 610b is connected in the through hole 410b, and the other end presses against the plate 230 in the axial z direction, thus elastically compressing it.

[0063] Please also refer to Figure 4B , Figure 5B as well as Figure 6 In some embodiments, when a third distance D3 exists between the first clamping portion 110 and the third clamping portion 210, the through hole 410a overlaps perpendicularly with the limiting hole 160 in the axial z direction. The first elastic limiting post 610a elastically recovers and at least partially enters the limiting hole 160. In some embodiments, when a third distance D3 exists between the first clamping portion 110 and the third clamping portion 210, the through hole 410a overlaps perpendicularly with the limiting hole 260 in the axial z direction. The first elastic limiting post 610b elastically recovers and at least partially enters the limiting hole 160.

[0064] In some embodiments, a loud clicking sound is emitted when the first elastic limiting posts 610a and 610b elastically recover and penetrate into the limiting holes 160 and 260. This allows the assembler to determine that the first elastic limiting posts 610a and 610b have popped out, that the positions of the first clamping arm 100 and the second clamping arm 200 are fixed, and that the distance between the clamping parts is suitable for clamping the electronic component. In other words, the first visual recognition area V1 and the second visual recognition area V2 can be used to determine that the electronic component has been clamped in place.

[0065] The assembly fixture 10 of this application may include both the first elastic limiting post 610a and the first elastic limiting post 610b, or may include only one of them as needed. In other words, this application does not intend to limit the number of the first elastic limiting posts 610a and 610b.

[0066] During assembly on the production line, if the assembly fixture 10 can be clamped to electronic components such as the water-cooling plate 30 and the central processing unit 20 without precise alignment, the assembly efficiency of the production line will be increased. The structure and function of the assembly fixture 10 for assisting alignment will be explained in detail below.

[0067] Please also refer to Figure 2 as well as Figure 5AIn this embodiment, the assembly fixture 10 further includes one or more pairs of limiting plates 14. The limiting plates 14 are connected to the base 300. The limiting plates 14 protrude from the side of the base 300 near the clamping portions (e.g., the first clamping portion 110, the second clamping portion 120, the third clamping portion 210, and / or the fourth clamping portion 220). A pair of limiting plates 14 are located on opposite sides of the first clamping arm 100 or the second clamping arm 200, respectively. The limiting plates 14 are configured to limit electronic components (e.g., ...) in the y-axis direction. Figure 1 The water-cooled plate 30 shown makes it easier for the first clamping arm 100 and the second clamping arm 200 to clamp.

[0068] Please continue to refer to this. Figure 2 as well as Figure 5A In this embodiment, the assembly fixture 10 further includes a second resilient limiting post 620. The second resilient limiting post 620 is connected to the base 300. The second resilient limiting post 620 protrudes from the side of the base 300 near the clamping portion (e.g., the first clamping portion 110, the second clamping portion 120, the third clamping portion 210, and / or the fourth clamping portion 220). The second resilient limiting post 620 is configured to limit electronic components (e.g., ...) in the axial x direction. Figure 1 (See water-cooled plate 30). In some embodiments, when the electronic component and the second elastic limiting post 620 overlap vertically in the axial z direction and compress the second elastic limiting post 620, the second elastic limiting post 620 is elastically compressed between the electronic component and the base 300. After the first clamping portion 110 and the third clamping portion 210 move towards each other and push the electronic component away from the second elastic limiting post 620, the second elastic limiting post 620 elastically recovers and pops out. In other words, if there is only a slight tilt (the electronic component is still located between the two limiting plates 14), the second elastic limiting post 620 will not affect the assembly, and the second elastic limiting post 620 can still pop out to provide a limiting function after clamping.

[0069] Please refer to Figure 7 . Figure 7A perspective view of an assembly fixture 10, a circuit board 50, and several other electronic components according to one embodiment of this application is shown. In this embodiment, the assembly fixture 10 clamps two electronic components, each including a water-cooled plate 30 and a central processing unit 20. The assembly fixture 10 can securely clamp the electronic components and place them on the circuit board 50. The assembly fixture 10 includes two abutment portions 16. The two abutment portions 16 are located on opposite sides of the assembly fixture 10. The abutment portions 16 are configured to abut against the sidewall portion 52 of the circuit board 50, so that the assembly fixture 10 can be securely placed on the circuit board 50. The water-cooled plate 30 and the central processing unit 20 are placed around a memory module 60 on the circuit board 50. The assembly fixture 10 includes an assembly guide hole 12. The assembly guide hole 12 can guide fasteners (e.g., screws) along the axial direction z to secure the water-cooled plate 30 and the central processing unit 20 to the circuit board 50. In addition to making the locking process more intuitive and convenient, the assembly guide hole 12 can also prevent users from accidentally damaging surrounding electronic components (such as memory module 60) during the locking process.

[0070] In some embodiments, circuit board 50 includes a multilayer printed board. In some embodiments, memory module 60 includes a dual in-line memory module (DIMM) or a dual in-line memory module socket (DIMM socket). Assembly fixture 10 is configured to securely place water cooling plate 30 and central processing unit 20 around memory module 60.

[0071] In one embodiment of this application, the assembly fixture can be used for assembling servers. The servers can be used for artificial intelligence (AI) computing, edge computing, and can also be used as 5G servers, cloud servers, or vehicle-to-everything (V2X) servers.

[0072] In summary, since the assembly fixture of this application includes a first clamping arm, a second clamping arm, and a driving component, it can conveniently clamp electronic components such as water-cooled plates and central processing units for assembly. Furthermore, the assembly fixture of this application also includes assembly guide holes for securing screws, a visual recognition area for assisting clamping, elastic limiting posts, and limiting plates, which can achieve the beneficial effect of improving assembly efficiency.
