Description

Technical Field

[0001] The invention relates to the technical field of server production, and in particular to a server assembly line. Background Art

[0002] The server includes a chassis and spare parts installed in the chassis, where the spare parts include a motherboard, processor, memory, hard disk, hard disk drive, power supply, and various connecting cables. In the later stage of server production, the spare parts need to be installed in the chassis to complete the assembly of the server.

[0003] In the server assembly factory, the chassis and spare parts that serve as assembly raw materials are already installed and come with outer packaging when they are delivered to the assembly factory. Therefore, before installing the spare parts in the chassis, it is necessary to remove the outer packaging of the chassis and spare parts, and disassemble the chassis body to prepare for the assembly of the server.

[0004] There are two existing assembly methods. One is to place a complete set of chassis and spare parts at an assembly station and complete it by one assembler. The disadvantage of this assembly method is that the assembler needs to complete multiple assembly operations independently, which is difficult for one assembler, making the server assembly time-consuming and the assembly efficiency extremely low.

[0005] The other is that the spare parts are placed in multiple assembly stations in sequence according to the assembly order, and the disassembled boxes are then transported to each assembly station in sequence, and the corresponding assembly workers complete the corresponding assembly operations, that is, different spare parts are completed by different assembly workers. Although this assembly method solves the problem of difficult assembly operations, the transportation of the disassembled boxes takes a lot of time, and the transportation must strictly follow the assembly order, which also causes the problem of long server assembly time and extremely low assembly efficiency.

[0006] In view of this, the inventor has made in-depth considerations and actively researched, improved and trial-produced the server assembly production process to solve the many deficiencies and inconveniences caused by the imperfections in the server assembly production process, and developed the present invention.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0029] like Figures 1 to 8 As shown, a preferred embodiment of a server assembly line of the present invention, the server assembly line includes a material preparation line 1, an assembly line 2 and a pallet 3, the material preparation line 1 and the assembly line 2 are connected, and the pallet 3 flows from the material preparation line 1 to the assembly line 2; wherein, the material preparation line 1 includes a double-speed chain main line 4: a first double-speed chain main line 4A, and a plurality of material preparation stations 4A1 are arranged on the first double-speed chain main line 4A; the assembly line 2 includes two double-speed chain main lines 4: a second double-speed chain main line 4B and a third double-speed chain main line 4C, one end of the first double-speed chain main line 4A is connected to the second double-speed chain main line 4B or the third double-speed chain main line 4C; a first transplanting mechanism 21 is installed between the second double-speed chain main line 4B and the third double-speed chain main line 4C, and the first transplanting mechanism 2 1 is used to move the pallet 3 between the second speed chain main line 4B and the third speed chain main line 4C; and at least one group of speed chain branches 22 arranged in pairs: the first speed chain branch line 22A and the second speed chain branch line 22B, the speed chain branch line 22 is matched with one side of the speed chain main line 4, and a plurality of assembly stations 221 are arranged on the speed chain branch line 22; a second transfer mechanism 23 is installed between the speed chain main line 4 and the speed chain branch line 22, and the second transfer mechanism 23 is used to move the pallet 3 between the speed chain main line 4 and the speed chain branch line 22; a third transfer mechanism 24 is installed between the first speed chain branch line 22A and the second speed chain branch line 22B, and the third transfer mechanism 24 is used to move the pallet 3 between the first speed chain branch line 22A and the second speed chain branch line 22B.

[0030] It should be noted that, in the present embodiment, three groups of paired speed chain branches 22 are respectively arranged on the opposite sides of the second speed chain main line 4B and the third speed chain main line 4C. The lengths of the speed chain main line 4 and the speed chain branch line 22 are not fixed, and the lengths of the speed chain main line 4 and the speed chain branch line 22 are determined according to the required material preparation station 4A1 and assembly station 221. In the present embodiment, 10 material preparation stations 4A1 are arranged on the first speed chain main line 4A, and 4 assembly stations 221 are arranged on each group of paired speed chain branches 22.

[0031] When assembling the server, the server's assembly raw materials: chassis, motherboard, processor, memory, hard disk, hard disk drive, power supply and various connecting wires, etc., are first placed in sequence on one side of the first speed chain main line 4A according to the assembly order, and correspond to each preparation station 4A1 respectively. The assembler performs preparation work at the preparation station 4A1. For example, at the first preparation station 4A1, the cardboard packaging of the chassis is removed and the chassis is placed on the pallet 3; at the second preparation station 4A1, the chassis is disassembled and neatly placed on the pallet 3; at the subsequent preparation station 4A1, the packaging of spare parts such as the chassis, motherboard, processor, memory, hard disk, hard disk drive, power supply and various connecting wires is removed and neatly placed on the pallet 3; at the last preparation station 4A1, the assembler can re-inspect all assembly raw materials to ensure that all assembly raw materials that are about to flow into the assembly line 2 have been placed and are in the specified positions.

[0032] In this embodiment, the pallet 3 flows into the second speed chain main line 4B after leaving the first speed chain main line 4A, and then moves between the second speed chain main line 4B and the third speed chain main line 4C through the first transfer mechanism 21, moves between the speed chain main line 4 and the speed chain branch line 22 through the second transfer mechanism 23, and moves between the first speed chain branch line 22A and the second speed chain branch line 22B through the third transfer mechanism 24, so that the pallet 3 can flow through each assembly station 221 in sequence. The assembler performs assembly work at the assembly station 221 to complete the assembly of spare parts such as the motherboard, processor, memory, hard disk, hard disk drive, power supply, and various connecting wires until the assembly of the server is completed.

[0033] The key point of the present invention is that the present invention is provided with a material preparation line 1, an assembly line 2 and a pallet 3. The pallet 3 flows from the material preparation line 1 to the assembly line 2, and passes through multiple material preparation stations 4A1 and assembly stations 221 in sequence. A single material preparation work and assembly work are completed at each material preparation station 4A1 and assembly station 221 respectively. The single assembly operation is simple to operate and easy to master for the assembler, and the assembly raw materials and chassis can flow to the assembler in an orderly manner on the material preparation line 1 and the assembly line 2 through the pallet 3, without the need for transportation and without causing confusion, thereby reducing the server assembly time and improving the assembly efficiency.

[0034] The above-mentioned server assembly line also includes an automatic cache machine 5, which is installed between the material preparation line 1 and the assembly line 2, and includes a body frame 51; a stacking bracket 52, the stacking bracket 52 is installed in the body frame 51; and two pallet robots 53: a feed pallet robot 53A and a discharge pallet robot 53B, the feed pallet robot 53A and the discharge pallet robot 53B are both installed on the body frame 51 and are respectively located on both sides of the stacking bracket 52.

[0035] When in use, the automatic cache machine 5 is installed between the material preparation line 1 and the assembly line 2, wherein the feed pallet robot 53A faces the material preparation line 1, and the discharge pallet robot 53B faces the assembly line 2; when the pallet 3 flows to the end on the first speed chain main line 4A, the feed pallet robot 53A extends to the end of the first speed chain main line 4A and takes the pallet 3, and then the feed pallet robot 53A moves into the stacking bracket 52 and places the pallet 3 on the stacking bracket 52. Multiple pallets 3 can be placed on the stacking bracket 52. When the assembly of the server is slow , cache the pallets 3 flowing from the preparation line 1; for the pallets 3 cached on the stacking bracket 52, the unloading pallet robot 53B can take the pallets 3 from the stacking bracket 52 to the assembly line 2 according to the assembly speed of the assembly line 2. When taking, the unloading pallet robot 53B extends into the stacking bracket 52 and takes the pallet 3. After that, the unloading pallet robot 53B moves to the assembly line 2, places the pallet 3 on the assembly line 2, and is transported to each assembly station 221 by the assembly line 2 to complete the assembly work of the complete set of servers.

[0036] The automatic caching machine 5 of the present invention is provided with a stacking tray 52 and two pallet robots 53. The feed pallet robot 53A can automatically take and move the pallet 3 with assembly raw materials to the stacking tray 52 for caching, and the discharge pallet robot 53B can automatically take and move the cached pallet 3 to the assembly line 2 to cooperate with the assembly of the complete set of servers, so that the operating speed of the assembly line 2 can adapt to the material assembly line 1.

[0037] The above-mentioned pallet robot 53 includes a horizontal moving unit 531, which is installed on the body frame 51; a vertical moving unit 532, which is installed on the horizontal moving unit 531; a longitudinal moving unit 533, which is installed on the vertical moving unit 532; and a pallet cantilever 534, which is installed on the longitudinal moving unit 533.

[0038] When in use, the pallet cantilever 534 is moved in the three directions of X, Y and Z axes by the horizontal moving unit 531, the vertical moving unit 532 and the longitudinal moving unit 533, so that the pallet cantilever 534 on the feeding pallet robot 53A can move back and forth between the material preparation line 1 and the stacking bracket 52, and the pallet cantilever 534 on the discharging pallet robot 53B can move back and forth between the stacking bracket 52 and the assembly line 2.

[0039] The above-mentioned longitudinal moving unit 533 includes a mounting seat 5331, which is mounted on the vertical moving unit 532; a guide rail assembly 5332, which is mounted on the mounting seat 5331, and the support plate cantilever 534 is movably fitted on the guide rail assembly 5332; a first transmission rack 5333, which is mounted on the bottom of the support plate cantilever 534; a first servo motor 5334, which is mounted on the guide rail assembly 5332; and a transmission gear set 5335, which is rotatably mounted on the guide rail assembly 5332, and the transmission gear set 5335 is transmission-connected to the first servo motor 5334 and meshes with the first transmission rack 5333.

[0040] Taking the feeding pallet manipulator 53A as an example, when the longitudinal moving unit 533 is in use, the first servo motor 5334 drives the transmission gear set 5335 to rotate, and the transmission gear set 5335 drives the pallet cantilever 534 to move on the guide rail assembly 5332 through the first transmission rack 5333. The different driving directions of the first servo motor 5334 also determine the different moving directions of the pallet cantilever 534, that is, the pallet cantilever 534 can be moved toward the material preparation line 1 to take the pallet 3, and the pallet cantilever 534 can also be moved toward the stacking bracket 52 to place the pallet 3 on the stacking bracket 52. The working principle of the unloading pallet manipulator 53B is the same as that of the feeding pallet manipulator 53A, which will not be repeated here.

[0041] The above-mentioned longitudinal moving unit 533 also includes a first guide wheel group 5336, and a first guide wheel groove 5341 is provided on the support plate cantilever 534; the first guide wheel group 5336 is rotatably installed on the guide rail assembly 5332, and the support plate cantilever 534 is movably connected to the first guide wheel group 5336 through the first guide wheel groove 5341.

[0042] The pallet cantilever 534 of the present invention is movably connected to the first guide wheel group 5336 through the first guide wheel groove 5341, which can reduce the friction between the pallet cantilever 534 and the guide rail assembly 5332, making the movement of the pallet cantilever 534 smoother; and, the guide rail assembly 5332 can support the pallet cantilever 534 through the first guide wheel group 5336, making the extended pallet cantilever 534 structure more solid and stable.

[0043] The above-mentioned pallet cantilever 534 includes an inner cantilever 5342, which is movably fitted on the guide rail assembly 5332, and a first transmission rack 5333 is installed at the bottom of the inner cantilever 5342; an outer cantilever 5343; and two groups of linkage assemblies 5344, and the outer cantilever 5343 is movably fitted on the inner cantilever 5342 through the two groups of linkage assemblies 5344, so that when the inner cantilever 5342 moves, the outer cantilever 5343 is driven to move.

[0044] When in use, driven by the first servo motor 5334, the transmission gear set 5335 can drive the inner cantilever 5342 to move and extend on the guide rail assembly 5332; during the movement of the inner cantilever 5342, the outer cantilever 5343 can be driven to move and extend on the inner cantilever 5342 through two sets of linkage assemblies 5344, thereby forming a secondary extension, lengthening the outward extension length of the pallet cantilever 534, so that the pallet cantilever 534 can support a larger area of ​​the bottom of the pallet 3, thereby forming a stable support for the pallet 3.

[0045] Both sets of linkage components 5344 include a fixed terminal 5346, which is installed on the guide rail component 5332; a linkage gear 5347, which is rotatably installed on one end of the inner cantilever 5342; a linkage terminal 5348, which is fixed on one end of the outer cantilever 5343; and a linkage chain 5349, one end of which is connected to the fixed terminal 5346, and the other end is connected to the linkage terminal 5348 after bypassing the linkage gear 5347; wherein the linkage gear 5347 and the linkage terminal 5348 are respectively located at the two ends of the pallet cantilever 534, and the installation directions of the two sets of linkage components 5344 are opposite.

[0046] When the inner cantilever 5342 extends toward the material preparation line 1, the inner cantilever 5342 drives a linkage gear 5347 in a linkage component 5344 to move toward the material preparation line 1. During the movement of the linkage gear 5347, it drives the linkage chain 5349 in the linkage component 5344 to move toward the material preparation line 1. The linkage chain 5349 pulls the outer cantilever 5343 toward the material preparation line 1 through the linkage terminal 5348 in the linkage component 5344, thereby forming a secondary extension toward the material preparation line 1. On the contrary, when the inner cantilever 5342 extends toward the stacking bracket 52, the inner cantilever 5342 drives the linkage gear 5347 in another group of linkage components 5344 to move toward the stacking bracket 52. During the movement of the linkage gear 5347, it drives the linkage chain 5349 in the group of linkage components 5344 to move toward the stacking bracket 52. The linkage chain 5349 pulls the outer cantilever 5343 toward the stacking bracket 52 through the linkage terminal 5348 in the group of linkage components 5344, thereby forming a secondary extension toward the stacking bracket 52.

[0047] The above-mentioned support plate cantilever 534 also includes a second guide wheel group 5345, and a second guide wheel groove 5340 is provided on the inner cantilever 5342; the second guide wheel group 5345 is rotatably installed on the outer cantilever 5343, and the outer cantilever 5343 is movably installed in the second guide wheel groove 5340 through the second guide wheel group 5345.

[0048] The outer cantilever 5343 of the present invention is movably installed in the second guide wheel groove 5340 through the second guide wheel group 5345, which can reduce the friction between the outer cantilever 5343 and the inner cantilever 5342, so that the movement of the outer cantilever 5343 is smoother; and the inner cantilever 5342 can support the outer cantilever 5343 through the second guide wheel groove 5340, so that the structure of the extended outer cantilever 5343 is more solid and stable.

[0049] The above-mentioned horizontal moving unit 531 includes a horizontal guide rail 5311, which is installed on the body frame 51; a second transmission rack 5312, which is installed on the horizontal guide rail 5311; a horizontal slider 5313, which is movably fitted on the horizontal guide rail 5311; and a second servo motor 5314, which is installed on the horizontal slider 5313, and the output end of the second servo motor 5314 is transmission-connected to the second transmission rack 5312.

[0050] The above-mentioned vertical moving unit 532 includes a vertical guide rail 5321, which is installed on the horizontal slider 5313; a third transmission rack 5322, which is installed on the vertical guide rail 5321; a vertical slider 5323, which is movably fitted on the vertical guide rail 5321; and a third servo motor 5324, which is installed on the vertical slider 5323, and the output end of the third servo motor 5324 is transmission-connected to the third transmission rack 5322.

[0051] When in use, driven by the second servo motor 5314, the second servo motor 5314 drives the horizontal slider 5313 to move on the horizontal slide rail through the second transmission rack 5312, thereby realizing the movement of the pallet cantilever 534 on the X-axis through the horizontal moving unit 531; and driven by the third servo motor 5324, the third servo motor 5324 drives the vertical slider 5323 to move on the vertical slide rail through the third transmission rack 5322, thereby realizing the movement of the pallet cantilever 534 on the Y-axis through the vertical moving unit 532.

[0052] The stack bracket 52 comprises a vertical support rod group 521, which is mounted on the machine frame 51; at least two layers of horizontal support rod groups 522 are evenly spaced on the vertical support rod group 521; and a cache rod group 523 is evenly spaced on each layer of horizontal support rod group 522.

[0053] The cache rod group 523 includes two cache rods 5231 , the width of the two cache rods 5231 is smaller than the width of the support plate cantilever 534 , and the height of the two cache rods 5231 is greater than the height of the support plate cantilever 534 .

[0054] In this embodiment, four layers of horizontal support rod groups 522 are installed at equal intervals on the vertical support rod group 521; four cache rod groups 523 are installed at equal intervals on each layer of horizontal support rod group 522, so that the stack bracket 52 can provide a position for a cache stack 3.

[0055] When in use, the pallet cantilever 534 is moved in the three directions of the X, Y and Z axes by the lateral moving unit 531, the vertical moving unit 532 and the longitudinal moving unit 533, so that the pallet cantilever 534 can be moved to the position corresponding to each buffer rod group 523. Because the width of the two buffer rods 5231 is smaller than the width of the pallet cantilever 534, and the height of the two buffer rods 5231 is greater than the height of the pallet cantilever 534; therefore, the pallet cantilever 534 with the stack 3 placed thereon can first move to the top of the buffer rod group 523, and then move downward toward the gap between the two buffer rods 5231 until the stack 3 is placed on the buffer rod group 523, and then withdraw from the gap between the two buffer rods 5231 to prepare for the buffering of the next stack 3. When the pallet 3 needs to be moved to the assembly line 2, the idle pallet cantilever 534 can first move and extend into the gap between the two cache rods 5231, and then move upward to lift the pallet 3 placed on the cache rod group 523, and then move the pallet 3 to the assembly line 2.

[0056] The server assembly line also includes a control system 8, which is electrically connected to the material preparation line 1, the automatic cache machine 5 and the assembly line 2 to control the material preparation line 1, the automatic cache machine 5 and the assembly line 2. The control system 8 includes a PLC controller (PLC controller is the full name of programmable logic controller, the full name in English is: Programmable Logic Controller), which is a controller commonly used in automation equipment, and is often used in conjunction with a photoelectric sensor to control the drive, and then control the working state of the material preparation line 1, the automatic cache machine 5 and the assembly line 2. By providing a control system 8 to control the material preparation line 1, the automatic cache machine 5 and the assembly line 2 to cooperate with the assembly of the server, automated production is achieved, and production efficiency is further improved.

[0057] The above-mentioned server assembly line also includes a pre-installation mechanism 6, which includes three reciprocating elevators 61: a first reciprocating elevator 61A, a second reciprocating elevator 61B and a third reciprocating elevator 61C, the lower layer of the second reciprocating elevator 61B is connected to the first speed chain main line 4A, and the lower layer of the third reciprocating elevator 61C is connected to the second speed chain main line 4B or the third speed chain main line 4C; and two layers of pre-installation assembly lines 62: an upper pre-installation assembly line 62A and a lower pre-installation assembly line 62B, the two ends of the lower pre-installation assembly line 62B are respectively connected to the lower layers of the first reciprocating elevator 61A and the second reciprocating elevator 61B, and a plurality of pre-installation stations are arranged on the lower pre-installation assembly line 62B, and the upper layers of the first reciprocating elevator 61A, the second reciprocating elevator 61B and the third reciprocating elevator 61C are connected in sequence through the upper pre-installation assembly line 62A.

[0058] During use, if the pallet 3 needs to flow directly from the material preparation line 1 to the assembly line 2, the pallet 3 flows from the first speed chain main line 4A to the lower level of the second reciprocating elevator 61B, and the second reciprocating elevator 61B lifts the pallet 3 to the upper level. After that, the pallet 3 flows through the upper pre-installation line 62A to the upper level of the third reciprocating elevator 61C, and the third reciprocating elevator 61C lowers the pallet 3 to the lower level, and then flows into the assembly line 2 through the second speed chain main line 4B or the third speed chain main line 4C.

[0059] In order to relieve the assembly pressure on the assembly line 2 and increase the assembly speed of the server, the pallet 3 can also flow from the lower layer of the second reciprocating elevator 61B to the lower pre-installation line 62B, and pass through multiple pre-installation stations on the lower pre-installation line 62B in sequence. The assemblers pre-install the assembly raw materials of the server at the pre-installation stations. For example, first remove the hard disk bracket on the chassis, install the hard disk on the hard disk bracket, and first plug some connecting wires into the motherboard or hard disk.

[0060] The above-mentioned reciprocating elevator 61 includes a lifting frame 611; a lifting body 612, which is installed in the lifting frame 611; and a connecting assembly line 613, which is installed on the lifting body 612 and rises and falls with the lifting body 612. The connecting assembly line 613 in each reciprocating elevator 61 is respectively connected to the adjacent pre-installation assembly line 62 and the double-speed chain main line 4; wherein, the second reciprocating elevator 61B is also equipped with a transplanting chain 614, which is movably fitted on the lifting frame 611 and connected to the first double-speed chain main line 4A.

[0061] When in use, the lifting body 612 in the second reciprocating elevator 61B brings the connecting assembly line 613 down to below the first speed chain main line 4A, and then the transfer chain 614 extends out to connect with the first speed chain main line 4A, so that the pallet 3 on the first speed chain main line 4A can flow onto the transfer chain 614, and then the lifting body 612 brings the connecting assembly line 613 up from the middle of the transfer chain 614 until the connecting assembly line 613 supports the pallet 3, at this time the connecting assembly line 613 is also connected with the adjacent lower pre-installation assembly line 62B, and then the transfer chain 614 retracts and returns to its original position, and the connecting assembly line 613 drives the pallet 3 to flow to the lower pre-installation assembly line 62B.

[0062] After the pre-installation is completed on the lower pre-installation line 62B, the pallet 3 flows to the docking line 613 in the first reciprocating elevator 61A, and then the first reciprocating elevator 61A lifts the pallet 3 to the upper level. Then, the pallet 3 flows through the upper pre-installation line 62A, the upper level of the second reciprocating elevator 61B, the upper pre-installation line 62A, the upper level of the third reciprocating elevator 61C and the lower level of the third reciprocating elevator 61C in turn, and finally flows into the assembly line 2 through the second speed chain main line 4B or the third speed chain main line 4C.

[0063] The above-mentioned server assembly line also includes a table set distribution system 7, which includes a table set distribution rack 71, which is cooperated with one side of the material preparation line 1; a weighing mechanism 72, which is cooperated with one side of the table set distribution price; and an AGV transport vehicle 73, which travels back and forth between the table set distribution rack 71 and the assembly line 2.

[0064] During use, the assembler can first remove the outer packaging of spare parts such as the motherboard, processor, memory, hard disk, hard disk drive, power supply and various connecting cables, and then use the weighing mechanism 72 to check the spare parts according to the designed weight of the spare parts to ensure that the quality of the spare parts used for installation is qualified. After that, the qualified spare parts are classified and placed on the table distribution rack 71. The assembler can quickly find the corresponding spare parts and place them on the pallet 3, thereby improving the assembly efficiency of the server.

[0065] On assembly line 2, when assemblers are installing spare parts such as motherboards, processors, memory, hard disks, hard disk drives, power supplies, and various connecting cables, if any spare parts are damaged, the corresponding spare parts can be resent from the table distribution rack 71 to the corresponding assembly station 221 on assembly line 2 via the AGV transport vehicle 73, without the need for manual resending, thereby realizing automated production and further improving the assembly efficiency of the server.
