Description

Technical Field

[0001] The present application relates to an assembly jig, and in particular to an assembly jig for assembling a water cooling plate. Background Art

[0002] When installing electronic components such as a central processing unit (CPU) and a water cooling plate, a jig is required to assemble them to improve assembly efficiency.

[0003] However, when using existing assembly jigs for assembly, not only are the steps complicated, the CPU is easy to fall off, and another set of jigs needs to be replaced when tightening the screws, which is very inconvenient to use.

[0004] Therefore, how to propose an assembly fixture that can solve the above problems is one of the problems that the industry is eager to invest research and development resources to solve. Summary of the invention

[0005] Based on this, an object of the present application is to provide an assembly jig that can solve the above problems.

[0006] The present application relates to an assembly jig including a base, a first clamping arm, a second clamping arm and a driving 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 driving member engages at least one of the first clamping arm and the second clamping arm. The driving member is configured to drive the first clamping arm and the second clamping arm to move in opposite directions, so that the first clamping portion and the third clamping portion move toward each other, and the second clamping portion and the fourth clamping portion move toward each other. The first clamping arm and the second clamping arm are configured to slide in parallel along an axial direction relative to the base. The third clamping portion is axially located between the first clamping portion and the second clamping portion. The second clamping portion is axially located between the third clamping portion and the fourth clamping portion.

[0007] In some embodiments, the first clamping arm further comprises a first meshing portion, and the second clamping arm further comprises a second meshing portion. One side of the driving member meshes with the first meshing portion, and the other side of the driving member meshes with the second meshing portion.

[0008] In some embodiments, the assembly jig further comprises a rotating member and an upper cover. The rotating member is connected to the driving member. The upper cover is fixed to the base. The upper cover covers the first clamping arm and the second clamping arm on a side away from the base. The rotating member passes through the upper cover and the rotating member is configured to receive a rotational force to cause the first clamping arm and the second clamping arm to move in opposite directions.

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

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

[0011] In some embodiments, the assembly jig further comprises an upper cover. The upper cover comprises a perforation. The first clamping arm and the second clamping arm are disposed between the upper cover and the base. At least one of the first clamping arm and the second clamping arm comprises a first visual identification area and a second visual identification area. When the first clamping portion and the third clamping portion are at a first distance apart, the perforation exposes the first visual identification area. When the second clamping portion and the fourth clamping portion are at a second distance apart that is less than the first distance, the perforation exposes the second visual identification area.

[0012] In some embodiments, the assembly jig further comprises two limit plates. The two limit plates are connected to the base. The two limit plates are respectively located on opposite sides of at least one of the first clamping arm and the second clamping arm. The two limit plates protrude from a side of the base close to the first clamping portion.

[0013] In some embodiments, the assembly jig further includes an upper cover disposed on the base and a first elastic limiting column configured to be connected to the upper cover. The first clamping arm includes a limiting hole corresponding to the first elastic limiting column. When the first clamping portion and the third clamping portion are at a first distance apart, the first elastic limiting column is elastically compressed. When the first clamping portion and the third clamping portion are at a second distance less than the first distance apart, the first elastic limiting column elastically recovers and at least partially enters the limiting hole.

[0014] In some embodiments, the assembly jig further includes a second elastic limiting column connected to the base and protruding from a side of the base close to the first clamping portion.

[0015] In summary, since the assembly jig of the present application includes a driving member, the first clamping arm and the second clamping arm can be driven to move in opposite directions so as to use each clamping part to firmly and conveniently clamp the central processing unit and the water-cooling plate. In addition, the assembly jig of the present application may also include features such as elastic limit columns and assembly holes. Through the above features, the production line assembly personnel can more conveniently and efficiently install the central processing unit and the water-cooling plate on the motherboard, thereby achieving the beneficial effect of improving the work efficiency of the production line.

DETAILED DESCRIPTION

[0030] The following disclosure will now be more fully described here through drawings and reference data, and some exemplary embodiments are depicted in the drawings. The application can be implemented in different forms and should not be limited by the embodiments mentioned below. However, these embodiments are provided to help a more complete understanding of the content of the application and fully convey the scope of the invention to those skilled in the art. The same reference numerals will refer to similar components throughout the entire text.

[0031] In addition, the illustrations provided in this application are drawn according to the actual scale. In order to maintain the simplicity of the specification, the scales of each component are not listed one by one. However, the scales and positions of each component should be regarded as part of the content of this specification.

[0032] Please refer to Figure 1 . Figure 1 The 3D diagram shows an assembly jig 10, a CPU 20, a water cooling plate 30, and a cooling water tank assembly 40 according to an embodiment of the present application. The assembly jig of the present invention is suitable for use on a server, for example.

[0033] In this embodiment, two water-cooling plates 30 are respectively installed on two central processing units 20. The cooling water tank assembly 40 includes a water tank body 42 and a water-cooling pipe 44. The water-cooling pipe 44 connects the water tank body 42 and the water-cooling plate 30. Obviously, the water tank body 42, the two water-cooling plates 30 and the two central processing units 20 connected by the water-cooling pipe 44 are bulky and difficult for one person to grasp and pick up. They are not easy to carry and assemble without the assistance of tools. The assembly jig 10 is configured to clamp the central processing unit 20 and / or the water-cooling plate 30. The assembly jig 10 can cover the top of the central processing unit 20 and / or the water-cooling plate 30 to avoid damage to the central processing unit 20 and / or the water-cooling plate 30 due to collision from above during transportation and movement. After the assembly jig 10 clamps the CPU 20 and / or the water cooling plate 30, the assembler can hold the water tank body 42 with one hand and the holding part G of the assembly jig 10 with the other hand. In this way, one person can easily carry the CPU 20, the water cooling plate 30 and the cooling water tank assembly 40.

[0034] It should be noted that the present application is not intended to limit the hardware that can be clamped and fixed by the assembly fixture 10. For the sake of simplicity, the "electronic components" mentioned herein may include two central processing units 20, two water cooling plates 30, a cooling water tank assembly 40 and / or other suitable electronic components.

[0041] Please refer to Figure 4A . Figure 4A FIG. 1 shows a top view of some components and electronic components of an assembly jig 10 according to an embodiment of the present application. Figure 4A For the sake of clarity, the following are omitted: Figure 2 In the embodiment, the driving member 500 may be a transmission gear. One side of the driving member 500 is meshed with the first meshing portion 150. The other side of the driving member 500 is meshed with the second meshing portion 250. The first meshing portion 150 and the second meshing portion 250 are located on opposite sides of the driving member 500.

[0042] Please refer to Figure 5A . Figure 5A Shows Figure 4A 1 is a bottom view of the assembly jig 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 direction x.

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

[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 connected to the base 300 in parallel with 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 relative to the base 300 in parallel along the axial direction x.

The protrusion B is located between the protrusion C and the protrusion D in the axial direction x. The protruding portion C is located between the protruding portion A and the protruding portion B in the axial direction x.

[0045] The operation method of the assembly jig 10 will be described in detail below.

[0046] The force can be applied to the assembly jig 10 in the following manner. Figure 4A as well as Figure 4B . Figure 4B FIG. 1 shows a top view of some components and electronic components of an assembly jig 10 according to another embodiment of the present application. Figure 4B For the sake of clarity, the Figure 2 The upper cover 400 shown in FIG. 1 is a diagram of an assembly jig 10. In the present embodiment, the assembly jig 10 further includes a rotating member 502. The rotating member 502 is connected to the driving member 500. The rotating member 502 is configured to receive a rotational force to rotate the driving member 500. In other words, the assembler can apply force to the rotating member 502 so that the driving member 500 drives the first clamping arm 100 and the second clamping arm 200 to slide relative to the base 300. In some embodiments, the first clamping arm 100 and the second clamping arm 200 may include a force application hole 102 and a force application hole 202, respectively. The force application hole 102 and the force application hole 202 are configured to receive a tensile force to cause the first clamping arm 100 and the second clamping arm 200 to slide relative to the base 300. Since the first clamping arm 100 and the second clamping arm 200 are located at 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 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 direction x by applying a rotational force F1 to the rotating member 502. In more detail, the first clamping arm 100 moves in the direction of the arrow A1 on the axial direction x, and the second clamping arm 200 moves in the direction of the arrow A2 on the axial direction x. The protruding portion A is close to the protruding portion C. The protruding portion B is close to the protruding portion D.

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

[0049] In some embodiments, the distance D3 and the distance D4 can be set to a suitable width for clamping the electronic component according to the size of the electronic component. For example, if the two clamped water cooling plates 30 are of the same size, the distance D3 is equal to the distance D4. It should be noted that the present application does not intend to limit the specific widths of the distances D3 and D4.

[0050] Accordingly, through the transmission of the driving member 500, the clamping parts can be moved toward each other to conveniently and firmly clamp the electronic components, thereby achieving the beneficial effect of improving the working efficiency of the production line.

[0051] In some embodiments of the present application, the driving member 500 is a transmission gear with a serrated edge. In some alternative embodiments, the driving member 500 can be replaced by one or more other components according to the needs of the operator, such as a stepper motor, a transmission shaft, a transmission belt, a transmission gear set formed by a plurality of 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 driving member 500 is a transmission gear, since the transmission gear is meshed with the first clamping arm 100 and the second clamping arm 200 at the same time, when the assembly jig 10 is repeatedly used to clamp multiple sets of electronic components, each clamping can accurately fix the electronic components in the same position relative to the base 300. In other words, in addition to the simple structure and convenient maintenance, the transmission gear can also make the assembler more intuitive and convenient when performing subsequent alignment installation. In some embodiments, the rotating member 502 can be automatically controlled and clamped by a robot arm and a server and artificial intelligence that control the robot arm.

[0052] It should be noted that the engagement of the driving member 500 with the clamping arm (e.g., the first clamping arm 100 and / or the second clamping arm 200) may include an implementation in which the driving member 500 is directly engaged with the clamping arm, and may also include an implementation in which the driving member 500 is indirectly engaged with the clamping arm via one or more gears.

[0053] Please also refer to Figure 4A and Figure 6 . Figure 6 A top view of the upper cover 400 of the assembly jig 10 according to an embodiment of the present application is shown. In some embodiments, the upper cover 400 includes multiple through holes with different functions. For example, the upper cover 400 may include a plurality of through holes 402 for locking fasteners, configured to allow fasteners (e.g., screws 401) to fix the upper cover 400 to the base 300 along the axial direction z. For example, the upper cover 400 may include one or two through holes 404 corresponding to the force application holes 102 and / or the force application holes 202, configured to allow the assembler to pass a finger through the through hole 404 to apply a tensile force to the force application holes 102 and / or the force application holes 202 along the axial direction x. For example, the upper cover 400 may include a through hole 406 configured to allow the rotating member 502 to pass through along the axial direction z. The through hole 406 can fix the relative position of the rotating member 502 and the upper cover 400. In more detail, the rotating member 502 rotates in the through hole 406 relative to the upper cover 400 , and the rotating member 502 and the through hole 406 do not move relative to each other.

[0054] Please continue to refer to Figure 4A and Figure 6 . In some embodiments, the assembly jig 10 also includes an assembly guide hole 12. The assembly guide hole 12 passes through the upper cover 400 and the base 300 along the axial direction z. In the axial direction z, the assembly guide hole 12 does not vertically 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 fix the electronic component, the assembly guide hole 12 is configured to vertically overlap with the assembly hole (not shown) on the electronic component in the axial direction z. For example, when the electronic component is clamped by the assembly jig 10 and placed on the mainboard, in some embodiments, since the assembly guide hole 12 and the assembly hole on the electronic component vertically overlap in the axial direction z, the assembler can directly insert the fastener (such as a screw) through the assembly guide hole 12 into the assembly hole to lock the electronic component to the mainboard, without removing the assembly jig 10 and replacing it with another set of jigs for locking. In addition, by assembling the guide hole 12, it is more convenient to use a tool such as a screwdriver to lock the fastener, and damage to the underlying mainboard during the locking process can also be avoided.

[0055] When the assembly line performs repeated assembly work, if there is a function to remind that the assembly has been fixed in place (clamped in place), the work efficiency of the assembler can be improved. The structure and function of the assembly fixture 10 to remind that the assembly has been completed will be described in detail below.

[0056] Please also refer to Figure 4A , Figure 5A as well as Figure 6 In some embodiments, the cover 400 includes a perforation 408 (in Figure 5A The first clamping arm 100 includes a first visual identification area V1 and a second visual identification area V2. The perforation 408 exposes the first visual identification area V1 or the second visual identification area V2 according to the position of the first clamping arm 100 and the second clamping arm 200 relative to the upper cover 400. The first visual identification area V1 and the second visual identification area V2 have different visual differences such as different colors, patterns, and lighting methods to visually assist production line assemblers in assembly. For example, the first visual identification area V1 is red, and the second visual identification area V2 is blue. Figure 4A and Figure 4B In some embodiments, when the first clamping portion 110 and the third clamping portion 210 have a first distance D1, the through hole 408 (at Figure 4A The first visual recognition area V1 is exposed (indicated by dotted lines in the figure).

[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, so that the first clamping portion 110 and the third clamping portion 210 slide toward each other and have 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 (at Figure 4B The second visual identification area V2 is exposed by the first visual identification area V1 and the second visual identification area V2 in the through hole 408. Accordingly, the assembler can judge the distance between the clamping parts by visually observing the first visual identification area V1 and the second visual identification area V2 in the through hole 408, in other words, whether the electronic component has been clamped.

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

[0059] In some embodiments, the first clamping arm 100 and the second clamping arm 200 both include a first visual identification area V1 and a second visual identification area V2, and the upper cover 400 includes two through holes 408. In some embodiments, the size of the second visual identification area V2 in the axial direction z is approximately the same as that of the through hole 408.

[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. The present application does not intend 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 jig 10 also includes first elastic limiting columns 610a, 610b. The upper cover 400 includes through holes 410a, 410b. The first elastic limiting columns 610a, 610b are detachably connected to the through holes 410a and 410b of the upper cover 400, respectively. The first elastic limiting column 610a is configured to fix the relative position of the upper cover 400 and the first clamping arm 100. The first elastic limiting column 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 elastic limiting column 610a. The second clamping arm 200 includes a limiting hole 260 corresponding to the first elastic limiting column 610b. When the through hole 410a vertically overlaps with the limiting hole 160 in the axial direction z, the first elastic limiting column 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 through hole 410b vertically overlaps with the limiting hole 260 in the axial direction z, the first elastic limiting column 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 direction z to pull the first elastic limiting columns 610a and 610b out of the through holes 410a and 410b, respectively.

[0062] Please also refer to Figure 4A , Figure 5A as well as Figure 6. In 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 column 610a does not vertically overlap with the limiting hole 160 in the axial direction z. One end of the first elastic limiting column 610a is connected in the through hole 410a and the other end squeezes the plate body 130 in the axial direction z and is elastically compressed. 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 column 610b does not vertically overlap with the limiting hole 260 in the axial direction z. One end of the first elastic limiting column 610b is connected in the through hole 410b and the other end squeezes the plate body 230 in the axial direction z and is elastically compressed.

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

[0064] In some embodiments, since the first elastic limiting pillars 610a, 610b elastically recover and penetrate into the limiting holes 160, 260, a loud snapping sound is emitted, and the assembler can judge that the first elastic limiting pillars 610a, 610b have been ejected, the positions of the first clamping arm 100 and the second clamping arm 200 have been fixed, and the distance between the clamping parts can properly clamp the electronic component. In other words, the first visual identification area V1 and the second visual identification area V2 can be used to judge that the electronic component has been clamped in place.

[0065] The assembly fixture 10 of the present application may include both the first elastic limiting column 610a and the first elastic limiting column 610b, or may include only one of them according to the requirements. In other words, the present application does not intend to limit the number of the first elastic limiting columns 610a and 610b.

[0066] When assembling on the production line, if the assembly jig 10 and the water cooling plate 30, the CPU 20 and other electronic components can be clamped without precise alignment, the assembly efficiency of the production line will be increased. The structure and function of the assembly jig 10 to assist alignment will be described in detail below.

[0067] Please also refer to Figure 2 as well as Figure 5AIn this embodiment, the assembly jig 10 further includes one or more pairs of limit plates 14. The limit plates 14 are connected to the base 300. The limit plates 14 protrude from one side of the base 300 close to 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). A pair of limit plates 14 are respectively located on opposite sides of the first clamping arm 100 or the second clamping arm 200. The limit plates 14 are configured to limit the electronic components (e.g., Figure 1 The water cooling plate 30 shown in the figure makes it easier for the first clamping arm 100 and the second clamping arm 200 to clamp.

[0068] Please continue to refer to Figure 2 as well as Figure 5A In this embodiment, the assembly jig 10 further includes a second elastic limiting column 620. The second elastic limiting column 620 is connected to the base 300. The second elastic limiting column 620 protrudes from a side of the base 300 close to 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 elastic limiting column 620 is configured to limit the electronic component (e.g., Figure 1 The water cooling plate 30 shown in the figure). In some embodiments, when the electronic component and the second elastic limiting column 620 overlap vertically in the axial direction z and squeeze the second elastic limiting column 620, the second elastic limiting column 620 is elastically compressed between the electronic component and the base 300. After the first clamping part 110 and the third clamping part 210 move toward each other and push the electronic component away from the second elastic limiting column 620, the second elastic limiting column 620 elastically recovers and pops out. In other words, if it is only slightly skewed (the electronic component is still located between the two limiting plates 14), the second elastic limiting column 620 will not affect the assembly, and the second elastic limiting column 620 can still pop out after clamping to provide a limiting function.

[0069] Please refer to Figure 7 . Figure 7A stereoscopic view of an assembly jig 10, a circuit board 50, and a plurality of other electronic components of an embodiment of the present application is shown. In this embodiment, the assembly jig 10 clamps two electronic components including a water cooling plate 30 and a central processing unit 20, respectively. The assembly jig 10 can firmly clamp the electronic components and place the electronic components on the circuit board 50. The assembly jig 10 includes two abutting portions 16. The two abutting portions 16 are respectively located on opposite sides of the assembly jig 10. The abutting portions 16 are configured to abut against the side wall portion 52 of the circuit board 50 so that the assembly jig 10 can be firmly placed on the circuit board 50. The water cooling plate 30 and the central processing unit 20 are placed around the memory module 60 on the circuit board 50. The assembly jig 10 includes an assembly guide hole 12. The assembly guide hole 12 can guide a fastener (such as a screw) to lock the water cooling plate 30 and the central processing unit 20 on the circuit board 50 along the axial direction z. The assembly guide hole 12 not only makes the locking process more intuitive and convenient, but also prevents the user from accidentally damaging surrounding electronic components (such as the memory module 60) during the locking process.

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

[0071] In one embodiment of the present application, the assembly fixture of the present application can be used for assembling a server. The server can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, cloud server, or Internet of Vehicles server.

[0072] In summary, since the assembly fixture of the present application includes a first clamping arm, a second clamping arm and a driving member, it can conveniently clamp electronic components such as a water cooling plate and a central processing unit for assembly. In addition, the assembly fixture of the present application also includes assembly guide holes for locking screws, visual identification areas for auxiliary clamping, elastic limit columns and limit plates, etc., which can achieve the beneficial effect of improving assembly efficiency.
