Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of server manufacturing equipment, in particular to a positioning and clamping and conveying auxiliary platform for the automatic assembly process of a server mainboard, which is especially suitable for the automatic production line scene with high requirements for position accuracy, clamping stability and conveying fluency in the server mainboard assembly process. BACKGROUND

[0002] In the large-scale production process of a server, the assembly of a mainboard is one of the core processes, and the assembly accuracy directly affects the running stability and service life of the server. At present, the assembly of a server mainboard mainly relies on a pipeline conveying combined with manual or mechanical arm operation, but the existing assembly platforms generally have the following technical defects: Firstly, the positioning and clamping stability of the mainboard is insufficient. Traditional assembly platforms mostly use a single clamping structure to fix the mainboard or its carrier, which is difficult to adjust the clamping force, and is prone to problems such as damage to the mainboard due to clamping that is too tight, and position deviation during the assembly process due to clamping that is too loose, and cannot adapt to the clamping needs of different specifications of placement frames, and has poor versatility.

[0003] Secondly, the switching coordination between conveying and positioning is poor. The switching between the conveying state and the positioning assembly state needs to be realized during the assembly process, and the guide mechanism of the existing platform is mostly a fixed structure, which is prone to jamming and deviation when switching, and cannot balance the horizontal stability during conveying and the precise positioning during assembly, affecting the assembly efficiency and accuracy.

[0004] Thirdly, the impact buffering capacity is lacking. Slight vibration or impact is inevitable during the pipeline conveying process, and the existing platform lacks effective buffering compensation structure, which is prone to cause relative displacement of the mainboard and the placement frame, especially in the assembly of precision components, and a small deviation may cause assembly failure.

[0005] Finally, the automation integration is low. The clamping, positioning and guide switching of the existing platform mostly need independent driving mechanism control, which has poor action coordination, is complicated to operate, and is difficult to adapt to the needs of high-speed automatic assembly production lines, which restricts the improvement of the overall assembly efficiency of the server.

[0006] Therefore, it has become a technical problem to be solved in the current server manufacturing equipment field to develop a server assembly platform with stable clamping, accurate positioning, smooth conveying, excellent buffering performance and strong automation coordination. SUMMARY

[0007] The application aims to provide a server assembly platform and a method for using the same to solve the poor coordination of server mainboard assembly conveying and positioning switching in the background art. To achieve the above-mentioned purpose, the application provides the following technical solutions: a server assembly platform, comprising a conveyor and a plurality of mounting plates fixedly connected to the conveyor belt of the conveyor, a core clamping and positioning structure is arranged on the mounting plate, and the core clamping and positioning structure comprises: A rotating drum is embedded and rotationally connected to the middle part of the top surface of the mounting plate, the inner wall bottom of the rotating drum is provided with two V-shaped limiting grooves, and the top surface of the rotating drum is hingedly provided with two deflection rods; A spline spring telescopic rod is arranged in the inner wall of the rotating drum, the lower end of the spline spring telescopic rod is a movable end and can only be vertically extended and retracted, two extrusion rods inside the rotating drum are fixedly connected to the side surface of the spline spring telescopic rod, the lower end of the extrusion rod extends to the lower side of the mounting plate and is fixedly connected with a magnetic block, a support frame is fixedly connected to the top of the spline spring telescopic rod, and a placing frame capable of being fixedly connected to the server mainboard is arranged on the outer side of the support frame and can slide forward and backward. A linkage clamping assembly comprises a support rod, a pull rod, a Z-shaped rod, a V-shaped clamping plate and a clamping plate, the support rod is limitingly and slidably arranged between the mounting plate and the support frame, one end of the support rod is hingedly connected to the end of the deflection rod away from the rotating drum, first spring telescopic rods are hingedly connected to the two sides of the support rod, one end of the first spring telescopic rod away from the support rod is hingedly connected to the opposite side of the mounting plate and the support frame, one end of the pull rod is hingedly connected to the two sides of the support rod, the other end of the pull rod is hingedly connected to one end of the Z-shaped rod, the middle part of the Z-shaped rod is hingedly connected to the support frame, the end of the Z-shaped rod away from the pull rod is hingedly connected to the V-shaped clamping plate, the clamping plate is L-shaped, is hingedly connected to the two ends of the V-shaped clamping plate, and is used for extruding and fixing the placing frame. When the movable end of the spline spring telescopic rod is driven by the magnetic block to move downward, the extrusion rod abuts against the V-shaped limiting groove to position the rotating drum, when the rotating drum is deflected, the support rod is pushed to move by the deflection rod, and the clamping plate is clamped to the placing frame through the linkage of the pull rod and the Z-shaped rod.

[0008] Preferably, two vertical and parallel limiting strips are fixedly connected to the front and rear sides of the inside of the conveyor frame, two parallel rods are hingedly connected to the two sides of the two ends of the mounting plate, one of the parallel rods is fixedly connected with an auxiliary pulley, and the auxiliary pulley is slidably arranged between the two limiting strips on the same side.

[0009] Preferably, the same end of the two parallel rods is hingedly connected to the two ends of one auxiliary rod, the two auxiliary rods are arranged in parallel, one of the auxiliary rods is hingedly connected with a pulling rod, the pulling rod is hingedly connected to the corresponding Z-shaped rod, and the other end of the other auxiliary rod is provided with a limiting pulley.

[0010] Preferably, the two auxiliary pulleys on the same side are vertically and upwardly and downwardly arranged in a staggered manner and are respectively attached to the inner side walls of the two limiting strips arranged in an upward and downward manner on the same side.

[0011] Preferably, it also includes a buffer reset structure, the buffer reset structure including a second spring telescopic rod, one end of the second spring telescopic rod is hinged to the bottom of the rotating drum, and the other end is hinged to the bottom of the mounting plate, and an auxiliary push plate is also fixedly connected to the bottom of the rotating drum.

[0012] Preferably, it also includes a drive control structure, which includes a support plate fixedly connected inside the conveyor frame. A first cylinder arranged horizontally is fixedly connected to the right side of the top surface of the support plate, an electromagnet is fixedly connected to the middle of the top surface, and a second cylinder is fixedly connected to the left side of the top surface. The output ends of the first cylinder and the second cylinder are at the same horizontal height as the auxiliary push plate.

[0013] Preferably, the first spring telescopic rod deflects synchronously with the support rod as they move in opposite directions, providing auxiliary thrust for the opposite movement of the support rod, and in the rotating drum positioning state, the deflecting rod is coaxial with the central axis of the support rod.

[0014] A method for using a server assembly platform includes the following steps: S1. Initial conveying stage: Fix the server motherboard in the placement frame, then fasten the placement frame to the outside of the support frame and adjust its position. The placement frame can slide back and forth along the support frame to adapt to the fixing requirements. The mounting plate moves with the conveyor belt. The auxiliary pulleys on the same side, which are staggered vertically, slide against the inner wall of the limit strip on the same side to ensure overall horizontal and stable conveying. S2, Clamping and Guiding Switching Stage: When the mounting plate moves to the position of the first cylinder, the first cylinder extends to push the auxiliary push plate at the bottom of the rotating drum, causing the rotating drum to rotate around the mounting plate, driving the deflection rod to deflect and pushing the support rod to move in opposite directions. The first spring telescopic rod deflects synchronously to provide auxiliary thrust. The support rod pulls the Z-shaped rod to deflect, causing the V-shaped clamping plate and the L-shaped clamping plates at both ends to press against the placement frame, thus clamping and fixing the main board and ensuring that it is located in the center of the mounting plate. At the same time, the Z-shaped rod drives the auxiliary rod to deflect by pulling the rod, causing the auxiliary pulley to move out of the limit bar. The limit pulley then abuts against the lower limit bar, completing the guide switching to enhance stability. S3, Buffering and Precise Positioning Stage: During transportation and assembly, if impact occurs, the second spring telescopic rod and the first spring telescopic rod retract to absorb shock, and the position of the placement frame is corrected through elastic reset to avoid displacement; After the mounting plate moves to the underside of the electromagnet, the electromagnet attracts the magnetic block, which drives the spline spring telescopic rod to move down, so that the pressing rod presses against the V-shaped limiting groove of the rotating cylinder to achieve precise positioning. At this time, the deflection rod and the support rod are coaxial, which further ensures the clamping stability and provides a guarantee for the assembly of the robotic arm.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The application has the advantages that clamping and fixing are accurate and stable, and the application is universal. The linkage structure of the rotating drum, the deflection rod, the supporting rod, the Z-shaped rod and the clamping plate cooperates with the auxiliary thrust of the first spring telescopic rod, so that the clamping plate can uniformly clamp the placement frame, and the placement frame and the internal server mainboard are ensured to be in the center position of the mounting plate. The clamping action is triggered by the deflection of the rotating drum driven by the air cylinder, and the clamping force can be adjusted by the elastic parameters of the spring telescopic rod, so that the mainboard can be prevented from being damaged by over-clamping and from being loosened and deviated, and the clamping demand of the placement frame of different specifications can be met, and the universality of the platform is improved.

[0016] The application has the advantages that the switching of the guide is smooth, and the stability of conveying and positioning is combined. The auxiliary pulley is designed to slide along the limiting strip in the conveying stage, so that the horizontal conveying accuracy of the mounting plate is ensured. The limiting pulley is switched to abut against the limiting strip in the assembly positioning stage, so that the stability during assembly is further improved. The switching action is completed synchronously through the linkage of the Z-shaped rod, the pulling rod and the auxiliary rod, so that independent driving is not needed, the action coordination is strong, the switching jamming and position deviation are avoided, and the stability of the sliding guide is further improved by the up-down staggered arrangement of the auxiliary pulleys on the same side, so that the inclination of the mounting plate is prevented.

[0017] The application has the advantages that the buffering compensation capability is excellent, and the assembly accuracy is ensured. The second spring telescopic rod and the first spring telescopic rod form a double buffering structure. When the placement frame and the mainboard are impacted and vibrated, the spring telescopic rod can absorb the impact force through contraction and deformation, and repeatedly corrects the position of the placement frame by using the elastic reset characteristic, so that the position deviation caused by impact is avoided, and a stable bearing foundation is provided for precise component assembly.

[0018] The application has the advantages that the positioning accuracy is high, and the automation assembly demand is met. The spline spring telescopic rod is driven to move downward by the electromagnetic iron adsorbing the magnetic block, so that the extrusion rod abuts against the V-shaped limiting groove of the rotating drum, the accurate positioning of the rotating drum is realized, and then the clamping stability and the position accuracy of the clamping plate to the placement frame are ensured. In the positioning state, the deflection rod and the supporting rod are coaxial, so that the structural stability is further improved, the precise assembly of the external mechanical arm is ensured, and the assembly error is greatly reduced.

[0019] The application has the advantages that the automation integration degree is high, and the assembly efficiency is improved. The overall structure is driven and controlled by the air cylinder and the electromagnetic iron, the clamping, positioning and guide switching actions are sequentially linked, manual intervention is not needed, the automation assembly line conveying and assembly process can be seamlessly adapted, the rotating drum is reset by the second air cylinder after assembly is completed, the components are automatically returned to the original position, the next round of assembly is prepared, and the assembly efficiency and the large-scale production capacity of the server mainboard are significantly improved.

[0031] The use method and advantages of the present application are as follows: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 Figure 1 Figure 2 Figure 3 Figure 4 Figures 5 to 9As shown, the server mainboard is installed in the placement frame, and the placement frame is clamped on the support frame 34. The support frame 34 with the clamped placement frame is conveyed with the mounting plate 3 through the conveyor 1.

When the mounting plate 3 with the server mainboard moves to the position of the first air cylinder 61, the first air cylinder 61 is extended to push the auxiliary push plate 51 to deflect, so as to drive the second spring telescopic rod 5 to deflect synchronously, and then drive the two deflection rods 37 to deflect and push the two support rods 38 to move away from each other.

At the same time, the Z-shaped rod (311) drives the auxiliary rod (42) to deflect by pulling the rod (43), so that the auxiliary pulley (41) moves out of the limit bar (2), and the limit pulley (44) abuts against the lower limit bar (2) to complete the guide switching to enhance stability; S3, Buffering and Precise Positioning Stage: During transportation and assembly, if impacted, the second spring telescopic rod (5) and the first spring telescopic rod (39) contract to absorb shock, and the placement frame position is corrected through elastic reset to avoid displacement; After the mounting plate (3) moves to the underside of the electromagnet (62), the electromagnet (62) attracts the magnetic block (36), which drives the spline spring telescopic rod (33) to move down, so that the pressing rod (35) presses against the V-shaped limiting groove (32) of the rotating cylinder (31) to achieve precise positioning. At this time, the deflection rod (37) and the support rod (38) are coaxial, further ensuring the clamping stability and providing a guarantee for the assembly of the robotic arm.
