Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a plug-in station device and plug-in method for server circuit boards. Background Technology

[0002] The server PCBA (Printed Circuit Board Assembly) is the core and physical carrier of the server hardware architecture. The server PCBA carries key components such as the central processing unit, memory, expansion slots, storage controllers, and network interfaces, and provides them with electrical connections and data paths.

[0003] Due to the complexity of the insertion process on server PCBAs, workbenches with certain functions are used for assistance. To facilitate the insertion operation, the insertion station of server PCBAs adopts an open design. This means that when the insertion process uses dispensing and soldering methods to fix the components, the exhaust fumes generated can easily be inhaled by workers, affecting their safety, and the exhaust fumes can also escape into the workshop.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] This application provides a plug-in station device and plug-in method for server circuit boards, so as to at least solve the problem of exhaust gas emission generated during the plug-in process that cannot be solved in related technologies.

[0006] This application provides a server circuit board insertion station device for inserting server circuit boards. The device includes an inner casing, an outer casing, and an air extraction assembly.

[0007] An inner box is fixedly connected inside the outer box. The inner box has multiple first air extraction holes on one side of its thickness direction. The outer box has multiple second air extraction holes circumferentially arranged on one side of its thickness direction. The second air extraction holes are arranged on the same side as the first air extraction holes, and the second air extraction holes are arranged around the first air extraction holes.

[0008] The extraction assembly is configured to extract air into a first extraction port and / or a second extraction port. When the air inlet end of the extraction assembly is connected to the first extraction port, the extraction assembly extracts air into the first extraction port to form an adsorption area for the server circuit board. When the air inlet end of the extraction assembly is connected to the second extraction port, the extraction assembly extracts air into the second extraction port to form a negative pressure area on the outer periphery of the server circuit board for isolating exhaust gases.

[0009] This application also provides a method for inserting components into a server circuit board, the method comprising:

[0010] The server circuit board is placed inside the outer casing, and the air extraction component is controlled to work. The air extraction component extracts air through the normally open end of the first valve to the first air extraction port to create multiple negative pressure points between the server circuit board and the inner casing.

[0011] After the air extraction assembly has been working for a period of time, the normally open end of the first valve is closed and the normally closed end of the first valve is opened. The air extraction assembly then extracts air through the normally closed end to the second air extraction port to create a negative pressure area around the server circuit board.

[0012] The server circuit board insertion station device and insertion method proposed in this application embodiment, by setting a first valve, cuts off the connection between the inner box and the air extraction component after the server circuit board is adsorbed, so as to keep the inside of the inner box in a negative pressure state, and connects the outer box and the air extraction component. The air extraction component extracts air through the second air extraction hole, so that a negative pressure area appears around the server circuit board, reducing the exhaust gas generated by the dispensing or welding process during the insertion of the server circuit board to be inhaled by the workers, ensuring the safety of the workers, and reducing air pollution inside the processing workshop.

[0034] 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.

[0035] The server PCBA (Printed Circuit Board Assembly) is the core and physical carrier of the server hardware architecture, highly integrating functions such as high-performance computing, large-capacity storage, high-speed networking, powerful power supply, and intelligent management onto a single circuit.

[0036] The insertion process on server PCBAs is quite complex, and related technologies often use functional workbenches for assistance. To facilitate insertion, server PCBA insertion workbenches are usually designed to be open, which makes it easy for workers to inhale the exhaust fumes generated during the gluing and soldering processes used to fix the components, affecting worker safety and allowing the fumes to escape into the workshop.

[0037] To address the issue of exhaust gas emission during the insertion process of server PCBAs (hereinafter referred to as server circuit boards), this application proposes a server circuit board insertion station device and insertion method.

[0038] By using an extraction component to draw air out, a negative pressure zone is created around the server circuit board, effectively reducing the overflow of exhaust gas generated during the server circuit board assembly process.

[0039] Reference Figure 1 As shown, the X-axis represents the length of the server circuit board insertion station, the Y-axis represents the width of the server circuit board insertion station, and the Z-axis represents the height of the server circuit board insertion station.

[0040] Reference Figure 1 As shown in the embodiment of this application, a server circuit board insertion station device is proposed, which is used to insert components into server circuit boards.

[0041] The server circuit board insertion station device includes a workbench 1, which includes a table surface and four legs. The workbench 1 is used to form an operating support for inserting server circuit boards.

[0042] A feeding groove 11 is provided on the surface of the workbench 1. The feeding groove 11 is configured as a through hole that extends through the thickness direction of the workbench surface. The shape of the feeding groove 11 can be adjusted according to the shape of the part to be passed through.

[0043] A support frame 2 and a conveying assembly 3 are installed below the workbench 1, as shown in the reference. Figure 1 As shown, the support frame 2 is a U-shaped frame, and is fixedly installed on one side of the bottom of the workbench 1. Conveying components 3 are fixedly installed on both inner walls of the support frame 2, and there is space between the two conveying components 3 for assisting in the transport of the server circuit board. The distance between the two conveying components 3 is adapted to the length of the outer casing 5.

[0044] The two conveying components 3 are aligned horizontally in the height direction to ensure stable support for the outer casing 5.

[0045] To facilitate the movement of the server circuit board in the height direction, a baffle 4 is provided above the workbench 1, and the baffle 4 extends along the height direction.

[0046] Reference Figure 1 As shown, the baffle 4 and the worktable 1 are vertically arranged. The baffle 4 is connected to the worktable 1 to improve the connection stability between the baffle 4 and the worktable 1, and also to improve the stability of the server circuit board's movement.

[0047] Of course, in some embodiments, the baffle 4 and the worktable 1 may not be arranged perpendicularly, as long as the installation of the baffle 4 and the passage of components are satisfied. This application does not limit the positional relationship between the baffle 4 and the worktable 1.

[0048] The baffle 4 has a through hole 41, which is configured to extend along the height direction. The through hole 41 communicates with the unloading groove 11 to provide space for transporting the server circuit board.

[0049] Reference Figure 1 , Figure 2 As shown, a reserved groove 21 is provided between the lower surfaces of the support frame 2 and the worktable 1, and the reserved groove 21 is located at the bottom of the feeding groove 11.

[0050] By setting a reserved slot 21, space is provided for the server circuit board and the structure for mounting the server circuit board, and the structure for mounting the server circuit board can resist the two conveying components 3, the conveying work after the server circuit board is inserted is realized.

[0051] Reference Figure 3 , Figure 4 As shown, the server circuit board insertion station device includes an outer casing 5 and an inner casing 6, with the inner casing 6 fixedly connected inside the outer casing 5. The inner casing 6 and the outer casing 5 can jointly support the server circuit board, or only the inner casing 6 can be used to support the server circuit board.

[0052] The inner box 6 is completely placed inside the cavity of the outer box 5, and the top of the inner box 6 is flush with or lower than the top opening of the outer box 5. This ensures that when the server circuit board is placed on top of the inner box 6, the edge of the server circuit board is within the negative pressure area of ​​the outer box 5. This is the basis for the outer box 5 to draw air and form a negative pressure area around the server circuit board. In other words, the outer box 5 needs to cover the surrounding space of the server circuit board.

[0053] The outer side wall of the inner box 6 and the inner side wall of the outer box 5 are rigidly connected by welding or bolting. Of course, those skilled in the art can adjust the connection method between the outer box 5 and the inner box 6 as needed.

[0054] The outer box 5 and the server circuit board that is adsorbed and fixed on the inner box 6 move down. The setting of the unloading groove 11 and the reserved groove 21 allows the outer box 5 to resist the two conveying devices. When the outer box 5 resists the two conveying components 3, the second valve 83 is opened, the pressure inside the inner box 6 is released, the server circuit board loses its fixation and falls. The two sides of the server circuit board are supported by the two conveying components 3, which meets the conveying work after the circuit board is inserted.

[0055] The unloading chute 11 and the reserved chute 21 provide space for the server circuit board, which is transported in conjunction with the outer box 5 and the inner box 6, to move to the top of the two conveying components 3.

[0056] Reference Figure 4 As shown, an annular gap is formed between the inner wall of the inner box 6 and the inner wall of the outer box 5. This annular gap is the negative pressure chamber of the outer box 5. When the air extraction component 7 extracts air from the outer box 5, a negative pressure is formed in the annular gap. The exhaust gas around the server circuit board is drawn into the outer box 5 through the second air extraction holes 51 at the top and bottom of the outer box 5, and then discharged through the second air guide pipe 73 in sequence.

[0057] The inner casing 6 has multiple first vent holes 61 on one end face along its thickness direction. (Refer to...) Figure 4 As shown, the first air extraction hole 61 is circumferentially spaced along one end face of the inner box 6 along its own thickness direction.

[0058] It should be noted that the first air extraction holes 61 can be evenly spaced circumferentially. Of course, the first air extraction holes 61 can also be unevenly spaced circumferentially.

[0059] In some implementations, the first vents 61 can be centrally located to form a concentrated adsorption area for the server circuit board.

[0060] Reference Figure 4 As shown, the outer casing 5 has a plurality of second vent holes 51 circumferentially arranged on one end face along its thickness direction. The circumferential arrangement of the second vent holes 51 facilitates the formation of an annular negative pressure area around the server circuit board. The first vent hole 61 and the second vent hole 51 are arranged on the same side, and the second vent hole 51 is located around the first vent hole 61.

[0061] The outer casing 5 has multiple second air extraction holes 51 arranged circumferentially on the same side as the first air extraction hole 61 in the inner casing 6, so as to form an annular negative pressure area around the server circuit board.

[0062] In some embodiments, the end face of the inner box 6 with the first vent 61 is flush with the end face of the outer box 5 with the second vent 51, or the end face of the inner box 6 with the first vent 61 is lower than the end face of the outer box 5 with the second vent 51.

[0063] The end face of the inner casing 6 with the first vent 61 serves as the bearing surface of the server circuit board, and the end face of the outer casing 5 with the second vent 51 determines the location of the negative pressure area of ​​the outer casing 5.

[0064] If the end face of the inner box 6 with the first vent 61 is flush with the end face of the outer box 5 with the second vent 51:

[0065] After the server circuit board is placed on the end face of the inner box 6, the upper surface and sides of the server circuit board are at the same level as or surrounded by the second vent 51 of the outer box 5. The negative pressure field formed by the second vent 51 of the outer box 5 can seamlessly wrap the outer space of the server circuit board. When the exhaust gas diffuses from the plug-in area of ​​the server circuit board (such as soldering points and glue dots), it will directly enter the effective coverage area of ​​the negative pressure field formed by the outer box 5, avoiding the problem of exhaust gas escaping across the negative pressure field due to the server circuit board protruding from the end face of the outer box 5.

[0066] If the end face of the inner box 6 where the first vent 61 is located is lower than the end face of the outer box 5 where the second vent 51 is located:

[0067] After the server circuit board is placed, it is entirely within the recessed space formed by the outer casing 5 (the end face of the outer casing 5 is higher than the upper surface of the server circuit board). The second exhaust port 51 is equivalent to forming an annular enclosure-type negative pressure inlet around the server circuit board. Even if the exhaust gas diffuses upward or obliquely, it will be blocked by the height of the end face of the outer casing 5 and captured by the second exhaust port 51, further reducing the exhaust gas escape path. In particular, the collection efficiency of light volatile organic compounds (which tend to float upward) is significantly improved.

[0068] Reference in some implementation methods Figure 3 , Figure 4 As shown, the second air extraction port 51 can be set at the bottom and top of the outer side of the outer casing 5.

[0069] Since the exhaust gas generated during the insertion process of the server circuit board will spread irregularly around the server circuit board, by setting the second exhaust hole 51 at the bottom and top of the outer side of the outer casing 5, a full-enclosed negative pressure coverage of the server circuit board can be achieved, reducing the dead angle of exhaust gas escape.

[0070] Reference Figure 3 , Figure 4 As shown, the server circuit board insertion station device also includes an air extraction component 7 and a first valve 81. The air extraction component 7 is configured to extract air from either the first air extraction port 61 or the second air extraction port 51. In some other embodiments, the air extraction component 7 can also extract air from both the first air extraction port 61 and the second air extraction port 51 simultaneously.

[0071] The first valve 81 is configured to connect the air inlet of the air extraction assembly 7 to the first air extraction port 61, and / or connect the air inlet of the air extraction assembly 7 to the second air extraction port 51.

[0072] When the air intake end of the air extraction component 7 is connected to the first air extraction hole 61, the air extraction component 7 extracts air from the first air extraction hole 61 to form an adsorption area for the server circuit board. At this time, the connection between the inner casing 6 and the server circuit board is realized, providing a basis for the subsequent movement of the server circuit board.

[0073] When the air intake end of the air extraction assembly 7 is connected to the second air extraction port 51, the air extraction assembly 7 draws air from the second air extraction port 51 to form a negative pressure area on the outer periphery of the server circuit board for isolating exhaust gas.

[0074] Specifically, the first valve 81 is configured as a three-way valve, which includes a valve body and a valve core. The valve body forms three ports, namely a common port, a normally open port, and a normally closed port.

[0075] Under normal conditions, the valve core of the three-way valve defaults to connecting the common end and the normally open end, and the airflow flows from the normally open end into the common end.

[0076] When the three-way valve is in the switching state, the valve core moves, blocking the flow path between the normally open end and the common end, while opening the flow path between the normally closed end and the common end, allowing airflow to flow from the normally closed end into the common end.

[0077] The normally open end of the three-way valve is fixedly connected to the inner casing 6 via the fourth air guide pipe 85, and the normally closed end of the three-way valve is fixedly connected to the outer casing 5 via the third air guide pipe 84. The common end of the three-way valve is connected to the air extraction assembly 7 via the second air guide pipe 73.

[0078] By controlling the three-way valve, the second air guide pipe 73 can be connected to the inner box 6 or to the inside of the outer box 5.

[0079] The server circuit board is placed inside the outer casing 5, and the outer casing 5 and the inner casing 6 fixedly connected inside the outer casing 5 support the server circuit board. Then, the air extraction component 7 is controlled to work. The air extraction component 7 extracts air from inside the inner casing 6 through the fourth air guide pipe 85 and the normally open second air guide pipe 73 of the three-way valve. The inner casing 6 has multiple first air extraction holes 61 located at the bottom of the server circuit board. At this time, multiple negative pressure points are generated between the inner casing and the server circuit board, and the server circuit board is attracted and fixed to the top of the inner casing 6.

[0080] After the air extraction assembly 7 has been working for a period of time, the normally open end of the control three-way valve is closed, the inner box 6 is kept under negative pressure, the normally closed end of the three-way valve is opened, and the air extraction assembly 7 extracts air from the inside of the outer box 5 through the third air guide pipe 84, the normally closed end of the three-way valve, and the second air guide pipe 73. Multiple second air extraction holes 51 are provided on the bottom and top of the outer side of the outer box 5.

[0081] The air extraction component 7 extracts air from the second air extraction hole 51, creating a negative pressure area around the server circuit board. This reduces the amount of exhaust gas generated during the component insertion process on the server circuit board that is inhaled by workers, ensuring worker safety and reducing air pollution inside the processing workshop.

[0082] In some embodiments, the server circuit board insertion station device further includes a first air duct 82 and a second valve 83. The first air duct 82 is used to connect the interior of the inner casing 6 with the external environment, and the second valve 83 is disposed on the first air duct 82. The second valve 83 is configured to open or close the interior of the inner casing 6 with the external environment.

[0083] When the second valve 83 is opened, the interior of the inner box 6 is connected to the external environment to depressurize the interior of the inner box 6, thereby releasing the adsorbed server circuit board.

[0084] Specifically, the second valve 83 is configured as a solenoid valve to relieve pressure in the inner chamber 6.

[0085] In some implementations, refer to Figure 6 As shown, the plug-in station device for the server circuit board also includes a first motor 91. The first motor 91 is located on the side of the air extraction assembly 7 away from the outer casing 5. The output end of the first motor 91 is connected to the air extraction assembly 7. When the first motor 91 is running, the output end of the first motor 91 drives the outer casing 5 to rotate through the air extraction assembly 7.

[0086] Reference Figure 3 , Figure 5 As shown, the plug-in station device for the server circuit board also includes a mounting base 92 and an electromagnet 93. The mounting base 92 is connected to the fixed end of the first motor 91, and the electromagnet 93 is located on the side of the mounting bracket 71 away from the second guide tube. The electromagnet 93 and the mounting base 92 are rotatably connected, and the electromagnet 93 is fixedly connected to the drive end of the first motor 91.

[0087] When the first motor 91 is running, the electromagnet 93 and the mounting base 92 are rotatably connected, and the first motor 91 drives the outer casing 5 to rotate through the electromagnet 93 and the mounting bracket 71.

[0088] In some embodiments, the fixed connection and rotatable connection between the electromagnet 93 and the mounting base 92 are achieved by magnetizing and demagnetizing the electromagnet 93.

[0089] After the first motor 91 finishes running, the control electromagnet 93 operates, and is fixedly connected to the mounting base 92 by magnetic force. The relative position between the electromagnet 93 and the mounting base 92 cannot change, and the mounting base 92 and the mounting bracket 71 are fixed together. It should be noted that the mounting base 92 here is made of iron.

[0090] Electromagnet 93 blocks the opening of mounting bracket 71 to facilitate the discharge of extracted gas.

[0091] In some implementations, refer to Figure 5 As shown, the air extraction assembly 7 includes a mounting bracket 71, an air pump 72, and a second air guide pipe 73. The mounting bracket 71 is connected to the output end of the first motor 91. The air pump 72 is mounted in the mounting bracket 71 and is configured to extract air from the first air extraction port 61 and / or the second air extraction port 51. The second air guide pipe 73 is connected to the air inlet end of the air pump 72 and the first valve 81. The air inlet end of the air pump 72 is fixedly connected to the second air guide pipe 73, and a three-way valve is fixedly connected between the second air guide pipe 73 and the outer casing 5.

[0092] By setting up the mounting bracket 71, a stable connection between the air pump 72 and the first motor 91 is facilitated, reducing shaking or detachment during movement or when stationary.

[0093] An air pump 72 and a second air guide pipe 73 are provided. The second air guide pipe 73 is connected to the air pump 72 and the first valve 81 respectively, so as to realize the air extraction of the inner box 6 or the outer box 5.

[0094] Reference Figure 5 As shown, the air extraction assembly 7 also includes a third valve 74, which is located inside the mounting bracket 71 and at the air outlet of the air extraction pump 72.

[0095] Reference Figure 5 As shown, the air extraction assembly 7 also includes a mounting rod 75, which connects the mounting frame 71 and the outer casing 5. The mounting rod 75 and the second air guide pipe 73 are spaced apart along the width direction of the outer casing 5. Under the action of the second air guide pipe 73 and the mounting rod 75, the mounting frame 71 moves synchronously with the outer casing 5.

[0096] In some implementations, in order to enable the server circuit board to move in the height direction, reference is made to... Figure 1 , Figure 7 As shown, the server circuit board insertion station device includes a sliding seat 101 and a pneumatic cylinder 102, and the sliding seat 101 is connected to the outer casing 5.

[0097] The movable end of the pneumatic cylinder 102 is connected to the sliding seat 101. The pneumatic cylinder 102 extends along the height direction and drives the sliding seat 101 to move along the height direction, so as to move the outer box 5 through the feeding chute 11 to the space between the two conveying components 3.

[0098] Reference Figure 7 As shown, the server circuit board insertion station device also includes a fixing plate 104, which is connected to the side of the baffle 4 away from the outer casing 5. The fixing plate 104 is used at least to install the fixing end of the pneumatic cylinder 102.

[0099] To enhance the stability of the entire device in the vertical direction, the server circuit board insertion station device also includes a telescopic rod 103. The movable end of the telescopic rod 103 is connected to the sliding seat 101, and the fixed end of the telescopic rod 103 is connected to the fixed horizontal plate 104.

[0100] Reference Figure 7 As shown, there are two telescopic rods 103, located on both sides of the pneumatic cylinder 102. The pneumatic cylinder 102 and the two telescopic rods 103 are fixedly inserted into the fixed horizontal plate 104.

[0101] The movable end of the pneumatic cylinder 102 and the movable ends of the two telescopic rods 103 are fixedly connected to the sliding seat 101. Under the action of the pneumatic cylinder 102 and the two telescopic rods 103, the sliding seat 101 can only move up and down. By controlling the movement of the pneumatic cylinder 102, the sliding seat 101 can move up and down, thereby realizing the synchronous up and down movement of the rack 107 and the outer box 5.

[0102] In some embodiments, a channel (not shown in the figure) is provided inside the sliding seat 101 along the horizontal movement direction of the outer casing 5.

[0103] Reference Figure 7 , Figure 8 As shown, the plug-in station device for the server circuit board also includes a second motor 105, a gear 106, and a rack 107.

[0104] The second motor 105 is located inside the sliding seat 101, and the fixed end of the second motor 105 is connected to the sliding seat 101. The gear 106 is located at the driving end of the second motor 105.

[0105] The rack 107 meshes with the gear 106. The rack 107 extends along the channel, and one end of the rack 107 is connected to the first motor 91. The second motor 105 drives the gear 106 to rotate counterclockwise, causing the rack 107 to move away from the outer casing 5.

[0106] By controlling the second motor 105 to work in the forward or reverse direction, the gear 106 rotates clockwise or counterclockwise, and the rack 107 moves forward (towards the outer housing 5) or backward (towards away from the outer housing 5).

[0107] To achieve the installation of the second motor 105, refer to Figure 7 As shown, the fixed vertical plates 110 fixedly connected inside the sliding seat 101 are all fixedly connected to the outer wall of the second motor 105.

[0108] To assist the server circuit board in moving horizontally, refer to Figure 7As shown, the server circuit board insertion station device also includes a guide rod 108. The guide rod 108 extends along the channel, one end of which is fixedly connected to the mounting base 92. The guide rod 108 passes through the channel and is movably connected to the channel to avoid the guide rod 108 from shifting.

[0109] When the pneumatic cylinder 102 drives the sliding seat 101 to move along the height direction, the sliding seat 101 drives the mounting seat 92 to move along with it via the rack 107 and guide rod 108. When the second motor 105 is running, the rack 107 and guide rod 108 move synchronously away from the outer casing 5.

[0110] In some embodiments, three guide rods 108 are provided. This application does not limit the number of guide rods 108; those skilled in the art can set the number as needed, as long as the guiding function is satisfied.

[0111] Taking the three guide rods 108 as an example, the rack 107 and the three guide rods 108 are inserted through the sliding seat 101, and one end of the rack 107 and the three guide rods 108 are fixedly connected to the mounting seat 92.

[0112] Under the action of the rack 107 and the three guide rods 108, the sliding seat 101, which is slidably connected to the baffle 4, moves up and down. The sliding seat 101 drives the mounting seat 92 to move up and down through the rack 107 and the three guide rods 108. The up and down movement of the mounting seat 92 drives the outer box 5 to move up and down.

[0113] Reference Figure 8 As shown, the plug-in station device for the server circuit board also includes a brake 109. The brake 109 is sleeved on the drive end of the second motor 105. The brake 109 is connected to the sliding seat 101. After the second motor 105 stops running, the brake 109 is controlled to work to brake the drive end of the second motor 105.

[0114] Specifically, the drive end of the second motor 105 is provided with a transmission shaft 1051, and the brake 109 is sleeved on the transmission shaft 1051.

[0115] When the brake 109 is working, the transmission shaft 1051 is braked, the transmission shaft 1051 and the gear 106 cannot rotate, the rack 107 is limited by the gear 106 and does not have relative displacement with the sliding seat 101, and the outer box 5 cannot be adjusted along the extension direction of the channel.

[0116] At this time, the mounting base 92 fixedly connected to the outside of the first motor 91 is rotatably connected to the electromagnet 93, and the output end of the first motor 91 is fixedly connected to the electromagnet 93. By controlling the first motor 91 to work, the electromagnet 93 can be controlled to rotate, and the mounting bracket 71 can be rotated.

[0117] This application also proposes a method for inserting server circuit boards, applied to the aforementioned insertion station device, for inserting server circuit boards. The method includes:

[0118] The server circuit board is placed inside the outer casing 5, and the air extraction component 7 is controlled to work. The air extraction component 7 extracts air from the first air extraction port 61 through the normally open end of the first valve 81 to create multiple negative pressure points between the server circuit board and the inner casing 6.

[0119] After the vacuum assembly 7 has been operating for a period of time, the normally open end of the first valve 81 is closed, and the interior of the inner chamber 6 remains under negative pressure. The normally closed end of the first valve 81 is then opened, and the vacuum assembly 7 evacuates air through the second evacuation port 51 to create a negative pressure area around the server circuit board.

[0120] During the aforementioned process of evacuating the inner box 6, the evacuation assembly 7 extracts the gas from the inner box 6 through the fourth vent pipe 85, the normally open end of the first valve 81, and the second vent pipe 73.

[0121] During the aforementioned process of evacuating the outer casing 5, the evacuation assembly 7 extracts the gas from the outer casing 5 through the third air guide pipe 84, the normally closed end of the first valve 81, and the second air guide pipe 73.

[0122] In the above steps, the server circuit board is first placed inside the outer casing 5, and the outer casing 5 and the inner casing 6 fixedly connected inside the outer casing 5 support the server circuit board. Then, multiple negative pressure points are formed between the first vent 61 and the server circuit board to magnetically fix the server circuit board to the top of the inner casing 6.

[0123] By creating a negative pressure area around the server circuit board, the amount of exhaust gas generated during the dispensing or soldering process on the server circuit board that is inhaled by workers is reduced, ensuring worker safety and reducing air pollution inside the processing workshop.

[0124] In some implementations, after the server circuit board is processed, the first motor 91 is controlled to run, and the first motor 91 drives the outer casing 5 to rotate so that the back of the server circuit board faces upward.

[0125] The second motor 105 is controlled to run, the gear 106 rotates along the first direction, and the rack 107 moves away from the outer box 5.

[0126] After the server circuit board moves to the top of the two conveying components 3, the control pneumatic cylinder 102 works to push the sliding seat 101 down, and the sliding seat 101 drives the outer box 5 and the server circuit board on the inner box 6 which is adsorbed and fixed down.

[0127] After the outer casing 5 presses against the conveying component 3, the second valve 83 is opened to depressurize the inside of the inner casing 6 and release the server circuit board.

[0128] The first direction mentioned above is counterclockwise. Depending on the observation position and the installation direction of gear 106, the specific direction of the first direction may vary, as long as it satisfies the movement direction of rack 107.

[0129] When the second motor 105 is running, under the action of the transmission shaft 1051 and the gear 106, the rack 107 moves backward, the mounting base 92 moves backward, the mounting bracket 71 moves backward, and the outer casing 5 and the server circuit board that is adsorbed and fixed on the inner casing 6 move backward.

[0130] During the process of moving the server circuit board downward, the control cylinder 102 works to push the sliding seat 101 downward. The sliding seat 101 drives the mounting seat 92 downward through the rack 107. The outer box 5 and the server circuit board that is adsorbed and fixed on the inner box 6 move downward. When the outer box 5 abuts against the two conveying components 3, the control valve 83 works to open, the pressure inside the inner box 6 is released, and the server circuit board loses its fixation and falls.

[0131] The first motor 91 drives the electromagnet 93, mounting bracket 71, second air duct 73, mounting rod 75, outer casing 5, and server circuit board fixed to the inner casing 6 to rotate. This adjusts the angle of the server circuit board to meet the needs of multi-angle insertion. By rotating the server circuit board 180° so that the back of the server circuit board faces upward, insertion can be performed on the back of the server circuit board, ensuring fast and convenient insertion and shortening the processing cycle of server circuit board insertion.

[0132] The position control component, consisting of a mounting bracket 71, an electromagnet 93, an air pump 72, a mounting base 92, a first motor 91, a rack 107, a sliding base 101, a pneumatic cylinder 102, and a second motor 105, returns to its initial state. The position control component completes one operation. The position control component meets the construction needs of clamping and fixing, angle adjustment, and conveying and unloading during the processing of the server circuit board. In the process of the position control component placing the server circuit board on top of the two conveying components 3, the staff has sufficient time to assemble the server circuit board and the plug-in components on the server circuit board.

[0133] The outer and inner casing structures in the aforementioned server circuit board insertion station can also be applied to the processing of various board components that generate waste gas during processing.

[0134] This application discloses a server circuit board insertion station device and insertion method. The device includes an inner box 6, an outer box 5, an air extraction component 7, and a first valve 81. The inner box 6 has a plurality of first air extraction holes 61 on one end face along its thickness direction. The outer box 5 has a plurality of second air extraction holes 51 circumferentially arranged on one end face along its thickness direction. The second air extraction holes 51 and the first air extraction holes 61 are arranged on the same side, and the second air extraction holes 51 are located around the first air extraction holes 61. The air extraction component 7 is configured to extract air from the first air extraction holes 61 and / or the second air extraction holes 51. The first valve 81 is configured to connect the air inlet end of the air extraction assembly 7 to the first air extraction port 61 and / or connect the air inlet end of the air extraction assembly 7 to the second air extraction port 51. When the air inlet end is connected to the first air extraction port 61, the air extraction assembly 7 extracts air from the first air extraction port 61 to form an adsorption area for the server circuit board. When the air inlet end is connected to the second air extraction port 51, the air extraction assembly 7 extracts air from the second air extraction port 51 to form a negative pressure area on the outer periphery of the server circuit board, thereby reducing the amount of exhaust gas generated by dispensing or soldering processes during the insertion process on the server circuit board from being inhaled by the staff.
