Description

Technical Field

[0001] This invention relates to the field of technology, and more specifically to an automatic assembly device for chassis radiators. Background Technology

[0002] During server assembly, the heatsink and CPU need to be assembled before being installed in the chassis. This requires high assembly precision. Currently, server assembly is mostly done manually, which results in high labor intensity for workers, low assembly precision, high component damage rate, and overall low efficiency. The material trays are also transported by tooling positioning on the conveyor line, which results in large space occupation of the conveyor line and inconvenience for material tray rotation, making it impossible to achieve repeated and efficient transportation. Summary of the Invention

[0003] Technical objective: To address the shortcomings of existing server assembly methods, this invention discloses an automated chassis heat sink assembly device that saves space, achieves efficient tray conveying and server assembly, and ensures assembly accuracy.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] An automatic assembly device for chassis heat sinks includes an automatic heat sink feeding conveyor line for conveying heat sinks, an automatic CPU feeding conveyor line for conveying CPUs, a chassis conveyor line for conveying chassis, an assembly robot for assembling CPUs and heat sinks, and an assembly robot for gripping heat sinks and inserting them into the chassis. The automatic heat sink feeding conveyor line adopts a double-layer structure. The upper layer is provided with a material separating mechanism for splitting stacked trays along the conveying direction and a full tray conveyor line for conveying the split trays to the side where the assembly robot is located. The lower layer is provided with an empty tray conveyor line. At the ends of the full tray conveyor line and the empty tray conveyor line, a lifting and transfer mechanism is provided for transferring empty trays from the upper layer to the lower empty tray conveyor line.

[0006] Preferably, the lifting and transfer mechanism of the present invention includes a feeding conveyor line, a discharging conveyor line, and lifting components disposed at the ends of the feeding conveyor line and the discharging conveyor line. The feeding conveyor line includes symmetrically arranged conveyor line supports. A cylinder is disposed on the opposite side of the conveyor line supports for pushing the conveyor line supports away from or towards each other. The distance of the input line on the conveyor line supports is adjusted by the cylinder to receive and release the material tray. A rear clamping mechanism is disposed on the outside of the input line of the conveyor line supports for clamping and fixing the material tray after it enters the input line.

[0007] Preferably, the lifting assembly of the present invention includes a lifting cylinder and a lifting frame disposed at the driving end of the lifting cylinder. The lifting frame has a support arm disposed parallel to the input line, and a suction cup is disposed on the support arm for adsorbing and fixing the bottom of the material tray during the lifting process.

[0008] Preferably, the present invention has two sets of support arms, which are arranged parallel to each other along the conveying direction of the discharge conveyor line, and form an opening at the end for the material tray to be removed.

[0009] Preferably, the material distribution mechanism of the present invention includes a lifting cylinder disposed below the inlet section of the full material tray conveyor line and material distribution cylinders disposed on both sides of the full material tray conveyor line. The lifting cylinder drives the upper full material tray to move up and down, and the material distribution cylinders separate the bottom full material tray from the other material trays above.

[0010] Preferably, in this invention, a protective cover suction cup is provided behind the material distribution mechanism along the conveying direction of the full material tray conveyor line. The protective cover of the radiator is picked up by the protective cover suction cup and lowered onto the recycling belt located below the full material tray conveyor line after the material tray passes.

[0011] Preferably, a flipping mechanism for flipping and adjusting the orientation of the radiator is provided between the assembly robot and the assembly robot of the present invention. The flipping mechanism includes a flipping platform for receiving and fixing the radiator. The flipping platform is connected to a flipping motor. A translation worktable for receiving the flipped radiator is provided below the flipping platform. The flipped radiator is transported to the assembly robot through the translation worktable.

[0012] Preferably, the chassis positioning assembly is provided on the chassis conveyor line of the present invention. The chassis positioning assembly includes a blocking cylinder disposed at the front end along the conveying direction of the chassis conveyor line, and a side positioning cylinder and a rear positioning cylinder that cooperate with the blocking cylinder to clamp and position the chassis.

[0013] Beneficial effects: The automatic assembly equipment for chassis heat sinks provided by the present invention has the following beneficial effects:

[0014] 1. This invention uses an automated production line to assemble the heat sink and the chassis, which can improve assembly efficiency. The material distribution mechanism is set up to split the material trays, which can feed materials in batches and buffer multiple material trays at a time, saving feeding time.

[0015] 2. The automatic radiator feeding and conveying line of the present invention adopts a double-layer structure and is equipped with a lifting and transfer mechanism at the end for rotating and conveying the material tray. After the radiator is picked up from the material tray, the material tray can be recycled and transported back to the feeding point for re-feeding, realizing cyclic feeding, ensuring that the assembly of radiators can be carried out continuously, and improving work efficiency.

[0016] 3. The feeding conveyor line of the lifting and transfer mechanism of the present invention is configured as an openable and closable structure, which can receive and fix a full material tray, and can also allow the lower lifting component to receive the material tray and move it to the discharge conveyor line after the heat sink needs to be removed, so as to quickly switch the material tray between the upper and lower layers. The openable and closable structure design can save the space occupied by the equipment, thereby improving the space utilization rate.

[0017] 4. The support arm of the present invention adopts a symmetrical structure with parallel design and forms an opening along the direction of the discharge conveyor line. The material tray is directly moved off the support arm by the power of the conveyor line without clamping and placing, saving equipment costs and speeding up the transfer efficiency of the material tray.

[0018] 5. The present invention uses a flipping platform and a translation worktable that match the structure of the radiator, which can easily flip and adjust the orientation of the radiator and position the radiator for easy gripping by the subsequent assembly robot. Attached Figure Description

Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made within the teachings of this disclosure without departing from the scope or spirit of this disclosure. For example, a feature shown or described as part of one embodiment may be used in conjunction with another embodiment to produce yet another embodiment. It is intended that this disclosure cover such modifications and variations that fall within the scope of the appended claims and their equivalents. Other objects, features, and aspects of this disclosure are disclosed or apparent from the following detailed description. It is to be understood by those skilled in the art that this discussion is merely a description of exemplary embodiments and is not intended to limit the broader aspects of this disclosure.

[0029] like Figures 1-7 The diagram shows an automatic assembly equipment for a chassis heatsink disclosed in this invention, including an automatic heatsink feeding conveyor line 1 for heatsink transportation, an automatic CPU feeding conveyor line 2 for CPU transportation, a chassis conveyor line 3 for chassis transportation, an assembly robot 4 for assembling the CPU and heatsink, and an assembly robot 5 for clamping the heatsink and installing it into the chassis. The automatic heatsink feeding conveyor line 1 adopts a double-layer structure. The upper layer is provided with a material separating mechanism 6 for splitting stacked trays along the conveying direction and a full tray conveyor line 7 for conveying the split trays to the side where the assembly robot 4 is located. The lower layer is provided with an empty tray conveyor line 8. At the ends of the full tray conveyor line 7 and the empty tray conveyor line 8, a lifting and transfer mechanism 9 is provided for transferring the empty trays from the upper layer to the lower empty tray conveyor line 8.

[0030] The double-layer structure design of the radiator automatic feeding conveyor line 1 can save equipment space, and the lifting and transfer mechanism 9 at the end realizes the transfer of the material tray between the upper and lower layers to ensure continuous feeding. Combined with the automatic assembly robot 4 and assembly robot 5, it can effectively improve the assembly efficiency.

[0031] like Figure 3 As shown, the lifting and transfer mechanism 9 of the present invention includes a feeding conveyor line, a discharging conveyor line, and lifting components disposed at the ends of the feeding and discharging conveyor lines. The feeding conveyor line includes symmetrically arranged conveyor line supports 10. A cylinder 11 is provided on the opposite side of the conveyor line supports 10 for pushing the conveyor line supports 10 away from or towards each other. The distance of the input line 12 on the conveyor line supports 10 is adjusted by the cylinder 11 to receive and release the material tray. A rear clamping mechanism 13 is provided on the outside of the input line 12 of the conveyor line supports 10 for clamping and fixing the material tray after it enters the input line. The lifting component includes a lifting cylinder 14 and a lifting frame disposed at the driving end of the lifting cylinder 14. The lifting frame has a support arm 15 arranged parallel to the input line. A suction cup 16 is provided on the support arm 15 for adsorbing and fixing the bottom of the material tray during the lifting process. There are two sets of support arms 15, which are arranged parallel to the conveying direction of the discharging conveyor line and form an opening at the end for the material tray to be removed.

[0032] When cylinder 11 pushes the conveyor support 10 closer together, the distance between the conveyor lines 12 can be made consistent with the distance of the full tray conveyor line 7, moving the full tray to the feeding conveyor line. The tray is then clamped and fixed by the rear clamping mechanism 13 so that the assembly robot 4 can clamp the radiator. The rear clamping mechanism 13 can use a cylinder or other structure to clamp and fix the tray. The driving end of the cylinder can be oriented towards the location of the tray. After the radiator is removed, the upgrading cylinder 14 rises, and the support arm 15 reaches below the tray and uses a suction cup to adhere and fix the tray. After cylinder 11 drives the conveyor support 10 to move away from each other and open up, the tray moves down to the discharge conveyor line under the action of the support arm 15. It is then moved out from between the support arms 15 by the discharge conveyor line and enters the empty tray conveyor line 8 that is connected to the discharge conveyor line.

[0033] The material distribution mechanism 6 of the present invention includes a lifting cylinder disposed below the inlet section of the full material tray conveyor line 7 and material distribution cylinders disposed on both sides of the full material tray conveyor line. The lifting cylinder drives the upper full material tray to move up and down, and the material distribution cylinders separate the bottom full material tray from the other material trays above. Along the conveying direction of the full material tray conveyor line 7, a protective cover suction cup 17 is provided behind the material distribution mechanism that can be raised and lowered. The protective cover of the radiator is picked up by the protective cover suction cup 17, and after the material tray passes, the protective cover is lowered onto the recycling belt 18 located below the full material tray conveyor line 7.

[0034] Before assembly, the CPU and heatsink need to be assembled first, such as... Figure 6 As shown, the assembly robot of the present invention includes a CPU gripper 24 and a heat sink gripper 25 that match the CPU and heat sink to be gripped. It also has a first vision component 26 for identifying and locating the gripped objects. All of these are located on the mobile end of the robot, thereby realizing the attachment of the CPU and the heat sink and the gripping and moving of the heat sink.

[0035] After attaching the CPU to the heatsink, the heatsink needs to be flipped to match its orientation when installed in the chassis. To this end, a flipping mechanism for flipping and adjusting the orientation of the heatsink is provided between the assembly robot 4 and the assembly robot 5 of this invention. The flipping mechanism includes a flipping platform 19 for receiving and fixing the heatsink. The flipping platform 19 is connected to a flipping motor 20. A translation worktable 30 for receiving the flipped heatsink is provided below the flipping platform 19. The flipped heatsink is transported to the assembly robot 5 through the translation worktable 30.

[0036] The chassis conveyor line 3 of the present invention is provided with a chassis positioning component. The chassis positioning component includes a blocking cylinder 21 located at the front end along the conveying direction of the chassis conveyor line, and a side positioning cylinder 22 and a rear positioning cylinder 23 that cooperate with the blocking cylinder 21 to clamp and position the chassis. After the chassis is conveyed to the position and positioned, the assembly robot 5 clamps the flipped radiator and inserts it into the chassis for locking and fixing.

[0037] like Figure 7 As shown, the assembly robot 5 of the present invention is also equipped with a heat sink gripper 25, and also with a protective cover gripper 27 for gripping the motherboard protective cover, an electric screwdriver 28 for locking the heat sink to the motherboard, and a second vision component 29. During assembly, the assembly robot 5 moves above the motherboard and uses the protective cover gripper 27 to remove the protective cover from the motherboard and place it in the recycling bin. The robot moves to the translation worktable 21 of the flipping mechanism and uses the heat sink gripper 25 to grip the heat sink and place it on the motherboard. The second vision component 29 positions and confirms that the heat sink is in place. The electric screwdriver 28 locks the heat sink to the motherboard. The vision component of the present invention can use existing CCD cameras, etc., to acquire images for position recognition and positioning.

[0038] In use, the assembly equipment of this invention has trays containing heat sinks stacked in the sorting mechanism 6. The sorting mechanism separates the bottom tray from the remaining trays above it. The separated trays are then fed into the lifting and transfer mechanism 9 by the full tray conveyor line 7. After the heat sink is picked up by the assembly robot 4 and placed into the flipping platform 19, the tray is moved down to the discharge conveyor line by the lifting cylinder 14 and sent out by the empty tray conveyor line 8. The CPUs conveyed by the CPU automatic loading conveyor line 2 are held and attached by the CPU grippers 24 of the assembly robot 4. The radiator is placed on a rotating platform 19 driven by a rotating motor 20. During the rotation, the cylinders on the rotating platform 19, which are used to clamp and position the radiator, keep it in a clamped state to prevent it from falling. The translation worktable 30 moves to the bottom of the rotating platform 19 to receive the rotated radiator and moves it to the clamping position of the assembly robot 5. The movement can be driven by an existing linear motion module. Finally, the assembly robot 5 clamps the radiator and puts it into the chassis of the chassis conveyor line 3. The assembly is completed after locking it with an electric screwdriver 28.
