Abstract
Description
Technical Field
[0001] This application relates to the field of server maintenance technology, and in particular to a cover plate removal and placement fixture. Background Technology
[0002] The protective cover of a server's CPU (Central Processing Unit) socket is primarily used to protect the CPU socket contacts from dust, static electricity, or other physical damage, ensuring proper CPU installation and stable system operation. Removing and placing the CPU socket protective cover is a common and crucial task during server motherboard production and maintenance. However, current methods for removing and placing the cover mainly rely on manual operation, which has the following significant shortcomings:
[0003] Without auxiliary tools, the operation demands a high level of skill and experience from the operators. When manually placing and removing the protective cover, operators often struggle with accurate alignment. For example, during installation, misalignment can easily damage the CPU socket contacts, causing pin or contact deformation. Furthermore, the lack of an effective fixing and clamping mechanism means the cover may not fit completely into the socket, leaving gaps and reducing its protective effect. Conversely, improper lifting of the cover can cause tilting or wobbling, leading to its edges scraping the socket contacts and causing damage. Therefore, the operational results are heavily influenced by the operator's hand stability and alignment accuracy, making repeatability difficult to guarantee. This increases uncertainty and potential error rates in the production process, affecting the contact quality between the CPU and the socket, and potentially reducing server reliability.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] like Figures 1 to 6As shown, this application provides a cover plate handling fixture, including: a positioning member 1, including a base plate 10 and a positioning part 11 connected to each other, the positioning part 11 being correspondingly provided with the cover plate 100 and the cover plate mounting position 200; a fixing block 2, disposed on the base plate 10 and located on the side of the base plate 10 away from the cover plate 100; and a gripper assembly 3, including a first gripper 31 and a second gripper 32 disposed opposite to each other along a first direction and rotatably connected to the fixing block 2; wherein, the first gripper 31 and the second gripper 32 each include a gripper body 33 and a clamping part 34 and a pressing part 35 located at both ends of the gripper body 33, the gripper body 33 being rotatably connected to the fixing block 2 so that the clamping part 34 and the pressing part 35 can selectively contact the cover plate 100 to clamp the cover plate 100 and drive the cover plate 100 to move or press the cover plate 100 into the cover plate mounting position 200.
[0034] Thus, the cover plate picking and placing fixture of this application has a simple structure. The precise positioning of the positioning component 1 is achieved through mechanical linkage between the fixing block 2 and the gripper assembly 3, which can lift the cover plate 100 in parallel. This avoids problems such as changes in the lifting angle of the cover plate 100 or even scratching the contact points caused by improper manual operation. It ensures accurate alignment of the cover plate picking and placing fixture on the cover plate 100 and the cover plate installation position 200, achieving stable picking and placing and accurate installation of the cover plate 100. This improves the accuracy and efficiency of picking and placing the cover plate 100, and significantly improves production efficiency and product yield. The dual design of the gripping part 34 and the pressing part 35 of the claw assembly 3 facilitates the removal and placement of the cover plate 100, simplifies the operation steps of removing and installing the cover plate 100, reduces the difficulty of removing and installing the cover plate 100, and solves the problem in related technologies where operators often damage the contacts of the CPU socket due to difficulty in accurate alignment when manually removing and placing the protective cover of the CPU socket. Thus, in the manufacturing process of server motherboards, it greatly improves the processing efficiency of CPU socket covers, reduces human error, and ensures the stable operation and performance of the server.
[0035] The application scenario of the cover plate picking and placing fixture of this application is mainly in the manufacturing and maintenance process of server motherboards, especially in the picking and placing of CPU socket covers. Through a simple mechanical transmission structure, without the need for an electronic control system, it achieves smooth picking and placing of the cover plate. This significantly reduces the defects that are easily caused by manual operation, effectively solving the problem of CPU socket cover plate handling in the server motherboard manufacturing process. The precise mechanical structure ensures accurate picking, placing, and installing of the CPU socket cover plate, reducing human error and having a significant positive impact on improving product quality and production line efficiency. In addition, the principle and mechanism of the cover plate picking and placing fixture of this application are not only applicable to specific industrial scenarios, but also have broad reference value for other fields that require precise handling of small objects.
[0036] Specifically, the substrate 10 of this application is a rectangular plate, with a first direction parallel to the width of the substrate 10 and a second direction parallel to the length of the substrate 10.
[0037] like Figures 4 to 6 As shown, both the first gripper 31 and the second gripper 32 include an elastic element 36, which is disposed between the gripper body 33 and the positioning element 1. The elastic action of the elastic element 36 causes the clamping part 34 to clamp onto the cover plate 100 and the pressing part 35 to separate from the cover plate 100, so that the clamping part 34 can be released from the cover plate 100 and the pressing part 35 can be brought into contact with the cover plate 100 by rotating the gripper body 33. At least one of the base plate 10 and the fixing block 2 is provided with a limiting hole 25 for limiting the end of the elastic element 36 away from the gripper body 33.
[0038] The gripper assembly 3 of the cover plate pick-and-place fixture of this application provides elastic elements 36 on the first gripper 31 and the second gripper 32. The elastic force of the elastic elements 36 ensures that the first gripper 31 and the second gripper 32 can be in an automatic clamping state without external force, preventing the cover plate 100 from accidentally falling off during the operation after being clamped. This improves the safety and reliability of the operation and is suitable for automated or semi-automated operation environments on server motherboard production lines. Especially in work processes that require frequent pick-and-place of the cover plate 100, it can significantly reduce manpower requirements and reduce the rate of operational errors.
[0039] Specifically, the elastic element 36 is a compression spring.
[0040] In one embodiment of this application, a limiting hole 25 is provided on the fixing block 2, and the limiting hole 25 is a through hole; the limiting hole 25 is not provided on the substrate 10.
[0041] In another embodiment of this application, a limiting hole 25 is provided on the fixing block 2, which is a through hole; a limiting hole 25 is also provided on the substrate 10, which is a blind hole, so as to prevent the elastic member 36 from coming out of the limiting hole 25.
[0042] like Figure 6 As shown, both the first gripper 31 and the second gripper 32 include a limiting post 37. The limiting post 37 is disposed on the gripper body 33 and located on the side of the gripper body 33 near the positioning member 1. The elastic member 36 is sleeved on the limiting post 37.
[0043] The gripper assembly 3 of the cover plate pick-and-place fixture of this application limits the elastic element 36 by setting limiting posts 37 on the first gripper 31 and the second gripper 32, ensuring the stability and correct direction of action of the elastic element 36 during the operation of the cover plate pick-and-place fixture, thereby ensuring the normal operation of the gripper assembly 3, improving the service life of the elastic element 36 and the stability and reliability of the gripper assembly 3, and avoiding misalignment or failure of the elastic element 36 after long-term use. It is suitable for server motherboard production lines, especially those operation links that require long-term stable operation, and can effectively reduce the frequency and cost of equipment maintenance.
[0044] Specifically, both the first gripper 31 and the second gripper 32 include two elastic elements 36 and two limiting posts 37. The two limiting posts 37 are spaced apart on both sides of the clamping part 35 along the second direction, and the two elastic elements 36 are respectively sleeved on the two limiting posts 37. The fixing block 2 is provided with four limiting holes 25. Two of the four limiting holes 25 are respectively provided with two elastic elements 36 of the first gripper 31, and the other two of the four limiting holes 25 are respectively provided with two elastic elements 36 of the second gripper 32.
[0045] The gripper assembly 3 of the cover plate handling fixture of this application achieves stable clamping and rapid release of the cover plate 100 by providing two elastic elements 36 and two limiting posts 37 on both the first gripper 31 and the second gripper 32. Specifically, the two limiting posts 37 are spaced apart on both sides of the clamping part 35 along the second direction, which ensures the balance when clamping the cover plate and avoids damage or displacement of the cover plate due to unilateral force; the elastic elements 36 are partially sleeved on the limiting posts 37, which can keep the gripper assembly 3 in a closed state when no external force is applied, forming a pre-clamping force on the cover plate 100, thereby reducing the shaking of the cover plate 100 during the handling process and avoiding the risk of the cover plate 100 accidentally falling off; the four limiting holes 25 provided on the fixing block 2 are connected to the first gripper 31 and the first gripper 32 and the second gripper 32. The elastic elements 36 on the second gripper 32 correspond one-to-one with the four limiting and fixing points of the elastic elements 36, ensuring the stability of the position of the elastic elements 36 during operation, while limiting the deformation range of the elastic elements to prevent excessive stretching or compression, ensuring reliability and durability in long-term use. This not only simplifies the operation process of picking up and placing the cover plate and improves work efficiency, but also significantly enhances the safety of the cover plate during the picking and placing process, reducing product damage caused by improper operation, and plays an important role in improving the production quality and efficiency of server motherboards.
[0046] like Figure 6As shown, the gripper body 33 includes a first plate 331, a second plate 332 and a rotating shaft 333 connected to each other. The rotating shaft 333 is located at the connection between the first plate 331 and the second plate 332 and is rotatably connected to the fixing block 2. The clamping part 34 is located at the end of the first plate 331 away from the second plate 332, and the pressing part 35 is located at the end of the second plate 332 away from the first plate 331.
[0047] The gripper assembly 3 of the cover plate pick-and-place fixture of this application realizes the synchronous rotation of the first gripper 31 and the second gripper 32 by setting a rotating shaft 333, thereby controlling the movement of the clamping part 34 and the pressing part 35, achieving the purpose of picking up and placing the cover plate 100, effectively operating the cover plate 100 and improving work efficiency.
[0048] The fixing block 2 is provided with a shaft hole 26 for mounting the end of the rotating shaft 333.
[0049] Specifically, the first included angle between the first plate 331 and the second plate 332 is an obtuse angle, and the opening of the first included angle is oriented toward the fixing block 2; wherein, the clamping part 34, the pressing part 35, the elastic element 36 and the limiting post 37 are all located inside the opening of the first included angle.
[0050] like Figure 6 As shown, both the first gripper 31 and the second gripper 32 include a handle 38. The handle 38 is connected to the gripper body 33 and is located on the side of the gripper body 33 away from the positioning member 1, so as to drive the gripper body 33 to rotate via the handle 38.
[0051] The first gripper 31 and the second gripper 32 of the cover plate pick-and-place fixture of this application use the handle 38 as the operating point. The first gripper 31 and the second gripper 32 are manually driven to rotate, thereby controlling the movement of the clamping part 34 and the pressing part 35. This improves the convenience and comfort of the pick-and-place operation, reduces the physical burden on the operator, and makes the pick-and-place operation of the cover plate 100 easier and more efficient. It is suitable for manual operation in the server motherboard production line, especially in workstations that require frequent operation, and can significantly improve operator satisfaction and work efficiency.
[0052] Specifically, the handle 38 is connected to the connection between the first plate 331 and the second plate 332. The handle 38 includes a third plate 381, a fourth plate 382, and a contact protrusion 383 connected sequentially in a direction away from the gripper body 33. The second included angle between the second plate 332 and the third plate 381 is an acute angle, and the opening of the second included angle is set towards the fixing block 2. The third included angle between the third plate 381 and the fourth plate 382 is an obtuse angle, and the opening of the third included angle is set towards the side away from the fixing block 2. The contact protrusion 383 is located on the side of the fourth plate 382 away from the fixing block 2 (i.e., inside the opening of the third included angle) to contact the operator's fingers for the operator to grip, preventing the cover plate removal fixture from detaching due to finger slippage.
[0053] like Figure 6 As shown, the clamping part 34 includes a gripper hook 341, which is disposed toward the side of the gripper body 33 near the positioning member 1; and / or the pressing part 35 includes a pressing post 351, which is located on the side of the gripper body 33 near the positioning member 1.
[0054] The gripper assembly 3 of the cover plate pick-and-place fixture of this application utilizes the hook-shaped structure of the gripper 341 and the planar structure at the end of the clamping column 351 to respectively achieve the functions of clamping and pressing the cover plate 100, thereby improving the accuracy and stability of the pick-and-place of the cover plate 100 and ensuring the safety of the cover plate 100 during the pick-and-place process. It is suitable for applications such as the pick-and-place operation of the cover plate 100 on the server motherboard production line, especially in those links where the pick-and-place accuracy of the cover plate 100 is required, which can effectively meet the production needs and ensure the stable installation of the cover plate 100.
[0055] like Figure 2 and Figure 3 As shown, the substrate 10 is provided with weight-reducing holes 12; and / or, the positioning part 11 is located on the side of the substrate 10 away from the fixing block 2, and the positioning part 11 includes a plurality of positioning protrusions 111 spaced apart around the periphery of the substrate 10, so as to form a positioning space 13 together with the substrate 10 for accommodating the cover plate 100 and the cover plate mounting position 200; and / or, two claw clearance grooves 14 are respectively provided on opposite sides of the substrate 10, the two claw clearance grooves 14 are respectively located on opposite sides of the fixing block 2, and the two claw clearance grooves 14 are spaced apart along the first direction, so as to avoid the claw bodies 33 of the first claw 31 and the second claw 32 respectively; and / or, the substrate 10 is provided with a first strip-shaped clearance groove 15 extending along the first direction, so as to avoid the pressing part 35; and / or, the side of the positioning part 11 away from the substrate 10 is provided with a chamfer 112.
[0056] The positioning component 1 of the cover plate pick-and-place fixture of this application reduces the overall weight of the fixture through the weight reduction hole 12, achieves accurate alignment of the cover plate 100 through the positioning protrusion 111 and the positioning space 13, ensures interference-free movement of the clamping and releasing process of the clamping assembly 3 and the clamping part 35 through the gripper clearance groove 14 and the first strip clearance groove 15, and reduces the frictional resistance of the positioning part 11 during the alignment process through the chamfer 112, thereby improving the smoothness of operation of the cover plate pick-and-place fixture and ensuring the accuracy and stability of the pick-and-place of the cover plate 100.
[0057] like Figure 2 and Figure 3 As shown, a plurality of weight-reducing holes 12 are spaced apart on the substrate 10, and the plurality of weight-reducing holes 12 are symmetrically distributed on opposite sides of the fixing block 2.
[0058] The positioning component 1 of the cover plate handling fixture of this application may be made of AL6061 material. Multiple weight-reducing holes 12 are designed on the base plate 10, symmetrically distributed on opposite sides of the fixing block 2. This significantly reduces the overall weight of the cover plate handling fixture, optimizing its center of gravity and ensuring its balance during operation. This allows operators to more easily manipulate the fixture when handling the CPU protective cover, reducing physical strain and improving work efficiency and comfort. Especially during the handling and alignment of the cover plate 100, it provides greater precision and stability, preventing cover plate 100 tilting or contact point damage due to imbalance. Furthermore, the design of the weight-reducing holes 12 also considers material conservation. By removing unnecessary materials, production costs are reduced, resource waste is minimized, reflecting an environmentally friendly production philosophy.
[0059] like Figure 2 and Figure 7 As shown, the cover plate 100 is a rectangular cover, and the cover plate mounting position 200 includes four mounting corners 210. The positioning part 11 includes four positioning protrusions 111 spaced around the periphery of the substrate 10. The four positioning protrusions 111 are provided in a one-to-one correspondence with the four corners 110 of the cover plate 100 and the four mounting corners 210 of the cover plate mounting position 200. The side of each positioning protrusion 111 away from the substrate 10 is provided with a chamfer 112 to guide the movement of the cover plate 100 and the cover plate mounting position 200 into the positioning space 13.
[0060] First, the positioning protrusions 111 of the positioning component 1 of the cover plate pick-and-place fixture of this application are provided with right-angle grooves that can be fitted one-to-one with the four corners 110 of the cover plate 100 and the four mounting corners 210 of the cover plate mounting position 200, forming a high-precision corner positioning mechanism. This allows the cover plate pick-and-place fixture to descend in contact with the four corners 110 and the four mounting corners 210 for accurate positioning, which greatly improves the efficiency and accuracy of the pick-and-place operation of the cover plate 100. It effectively avoids problems such as misalignment of the cover plate 100 or damage to contacts and pins caused by positional deviation of the cover plate 100, thereby protecting the integrity of the CPU socket. Secondly, each positioning protrusion 111 has a chamfer 112 on the side away from the substrate 10. This is a guiding structure that guides the cover plate 100 and other components smoothly into the positioning space 13 when the four positioning protrusions 111 of the positioning component 1 are positioned. This reduces the difficulty of operation and allows even non-professionals to quickly and accurately complete the positioning and installation of the cover plate 100, reducing the probability of human error. This design also simplifies the operation steps, shortens the time for removing and placing the CPU protective cover, improves the working efficiency of the server motherboard production line, and reduces the additional losses caused by repeated removal and placement of the cover plate during the production process. It has a significant positive impact on improving product quality and reducing production costs. It not only enhances the convenience and safety of removing and placing the cover plate 100, but also further optimizes the production process, demonstrating its great potential in improving industrial production efficiency and product quality.
[0061] Specifically, each gripper clearance groove 14 is provided with a limiting protrusion 17. Each limiting protrusion 17 is located on the side wall of the corresponding gripper clearance groove 14 near the other gripper clearance groove 14, so as to contact the first plate 331 on the gripper body 33 of the first gripper 31 and the second gripper 32, so as to limit the rotation of the first gripper 31 and the second gripper 32, so as to prevent the first gripper 31 and the second gripper 32 from rotating too much under the action of the corresponding elastic member 36, which would cause the corresponding elastic member 36 to disengage from the corresponding limiting hole 25 and set the disengagement limiting post 37, thereby causing the first gripper 31 and the second gripper 32 to fail.
[0062] The positioning component 1 of the cover plate pick-and-place fixture of this application achieves effective control of the rotation angle of the first gripper 31 and the second gripper 32 by setting a limiting protrusion 17 in the gripper clearance groove 14. When the first gripper 31 and the second gripper 32 rotate under the action of the elastic member 36, the limiting protrusion 17 contacts the first plate 331 on the gripper body 33 to limit the rotation range of the first gripper 31 and the second gripper 32, prevent the elastic member 36 from accidentally coming out of the limiting hole 25, ensure the stability of the elastic member during use, and prevent the problem of functional failure of the first gripper 31 and the second gripper 32 caused by the misalignment or loss of the elastic member 36. This is crucial for maintaining the normal working state of the fixture and avoids the risk of component damage or operator injury caused by excessive opening, thereby improving the safety factor of the fixture in actual production.
[0063] like Figure 4 and Figure 5 As shown, the fixing block 2 includes: a support plate 21, which is mounted on the base plate 10; two mounting side plates 22, which are spaced apart along a second direction on opposite sides of the support plate 21 and connected to the support plate 21 respectively; wherein, the length of the support plate 21 in the first direction is less than the distance between the rotation axis of the first gripper 31 and the rotation axis of the second gripper 32, and both sides of the gripper body 33 of the first gripper 31 and both sides of the gripper body 33 of the second gripper 32 are rotatably connected to the two mounting side plates 22 respectively.
[0064] The cover plate pick-and-place fixture of this application consists of a support plate 21 and a mounting side plate 22 forming a fixing block 2, which provides stable support and guidance for the gripper assembly 3, ensuring the normal operation of the gripper assembly 3, improving the structural stability and operational reliability of the fixture, and reducing the failure rate caused by the structural instability of the gripper assembly 3. In addition, the limitation that the length of the support plate 21 in the first direction is less than the distance between the rotation axis of the first gripper 31 and the rotation axis of the second gripper 32 ensures that the support plate 21, while playing the role of connecting with the positioning member 1, avoids interference with the movement of the first gripper 31 and the second gripper 32 of the gripper assembly 3, so that the first gripper 31 and the second gripper 32 can maintain the clamping state of the cover plate 100 without the action of external force.
[0065] The support plate 21 is provided with a limit hole 25, and the two mounting side plates 22 are respectively provided with a pivot hole 26.
[0066] like Figure 4 and Figure 5 As shown, the support plate 21 is provided with a second strip-shaped clearance groove 23 extending in the first direction to avoid the pressing part 35; and / or, the length of the support plate 21 in the first direction is less than the length of the two mounting side plates 22 in the first direction.
[0067] The fixing block 2 of the cover plate pick-and-place fixture of this application ensures interference-free movement of the clamping and releasing processes of the gripper assembly 3 and the clamping part 35 by setting a second strip-shaped clearance groove 23. By setting the length difference between the support plate 21 and the mounting side plate 22, the mounting side plate 22 can play the role of rotating connection with the gripper assembly 3 while avoiding interference of the support plate 21 on the movement of the first gripper 31 and the second gripper 32 of the gripper assembly 3. This optimizes the spatial layout of the cover plate pick-and-place fixture, improves the compactness of the structure and the flexibility of operation, improves the operating efficiency and space utilization of the fixture, reduces interference factors in the operation process, and improves the efficiency and stability of the clamping and pressing process.
[0068] like Figure 2 , Figure 3 and Figure 5 As shown, the substrate 10 and the fixing block 2 are connected by a plurality of fasteners; wherein, the substrate 10 is provided with a plurality of first through holes 16 at intervals, and the fixing block 2 is provided with a plurality of first threaded holes 24 at intervals. The plurality of first through holes 16 and the plurality of first threaded holes 24 are respectively provided with a plurality of fasteners in a one-to-one correspondence. The threaded end of each fastener passes through the corresponding first through hole 16 and is threadedly connected to the corresponding first threaded hole 24.
[0069] Multiple first threaded holes 24 are provided on the support plate 21 and are symmetrically arranged on opposite sides of the second strip-shaped clearance groove 23.
[0070] The base plate 10 and the fixing block 2 of the cover plate picking and placing fixture of this application are firmly connected by multiple fasteners, which ensures the overall structural strength and stability of the cover plate picking and placing fixture, improves the durability and reliability of the cover plate picking and placing fixture, reduces the failure rate caused by structural loosening, and ensures the smooth operation of the cover plate 100 picking and placing.
[0071] The process of using the cover plate removal and placement fixture in this application is as follows:
[0072] (1) The operator pinches the handles 38 of the first gripper 31 and the second gripper 32. As the two handles 38 approach each other, the first gripper 31 and the second gripper 32 rotate around their respective rotation axes 333, so that the gripping hooks 341 of the gripping parts 34 of the first gripper 31 and the second gripper 32 open. The four positioning protrusions 111 of the positioning member 1 move down along the four mounting corners 210 until they reach the predetermined position. The operator releases the two handles 38 so that the two hooks 341 close synchronously to hook the two sides of the cover plate 100 respectively, so as to fix the cover plate 100 and ensure that the cover plate 100 is stable and does not move relative to the cover plate removal fixture during subsequent operations. The operator only needs to lift the cover plate removal fixture gently to pull up and remove the cover plate 100 together.
[0073] (2) After being removed, the cover plate 100 remains clamped by the cover plate removal fixture and can be put back into the cover plate installation position 200 after testing at the cover plate installation position 200. At this time, the operator squeezes the handles 38 of the first clamp 31 and the second clamp 32 again to make the clamping column 351 of the clamping part 35 generate a slight downward pressure on the cover plate 100, so as to press the cover plate 100 onto the four installation corners 210, thereby achieving seamless installation and stable sealing of the cover plate 100; then, the operator continues to squeeze the handles 38 of the first clamp 31 and the second clamp 32 to remove the cover plate removal fixture, and finally, the operator releases the cover plate removal fixture.
[0074] These smooth operating procedures not only simplify the process of picking up and placing the cover plate 100, but also effectively avoid the risk of damage that may be caused by manual operation, ensuring that every picking up and placing of the cover plate 100 is safe, accurate and efficient, and greatly optimizing the production environment.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application.
