Description

Technical Field

[0001] This application relates to the field of chip manufacturing technology, and in particular to a vacuum degassing system. Background Technology

[0002] In electronic packaging processes, chips in PCBs (Printed Circuit Boards) typically require underfill adhesive. This underfill adhesive is used to fill the tiny gaps between the chip and the substrate, fixing the chip to the substrate and preventing it from falling off during subsequent processing or use.

[0003] After applying the underfill adhesive, a defoaming process is usually required to prevent air bubbles in the underfill adhesive from causing stress concentration in the encapsulation layer, leading to cracking and damage to circuit connections. In related technologies, vacuum pressure defoaming equipment is mostly a tank structure, while PCB production lines use an assembly line method for transportation, making the connection between the two difficult. Therefore, the loading and unloading of vacuum pressure defoaming equipment is mostly done manually, which is not only inefficient and costly in terms of labor, but also unstable and may cause product tilting, affecting product quality. Utility Model Content

[0004] Therefore, this application provides a vacuum defoaming system that can improve the material handling efficiency and handling stability.

[0005] Specifically, the following technical solutions are included:

[0006] This application provides a vacuum degassing system, which includes an offline device, a vacuum pressurizing device, an online device, a material handling device, and a material carrier.

[0007] The offline equipment, the vacuum pressurization equipment, and the online equipment are arranged along the first direction;

[0008] The material handling device includes a first guide rail and a material handling part. The first guide rail extends along the first direction, and the material handling part is movably connected to the first guide rail and can move along the first direction, the second direction, and the third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0009] In the technical solution of this application, since the material handling equipment has a first guide rail extending along a first direction, and the material handling part is movably connected to the first guide rail, the material handling part can move and transport the load along the first direction between the offline equipment, the vacuum pressurization equipment, and the online equipment. Since the material handling part can also move along a second direction and a third direction, the material handling part can replace manual operation, flexibly pick up and put down the load, realize the automated handling of materials in the load, reduce labor costs, improve the handling efficiency of materials, increase production capacity, and improve handling stability, which can avoid material tilting and improve product yield. The setting of the material handling equipment improves the automation and intelligence of the vacuum degassing system, provides a foundation for intelligent production, and enables the vacuum degassing system to be applied to smart factories.

[0010] In one possible implementation, the material handling device further includes a second guide rail and a third guide rail, the second guide rail being movably connected to the first guide rail and the third guide rail respectively, the second guide rail extending along the second direction, the third guide rail extending along the third direction, and the material handling unit being movably mounted on the third guide rail.

[0011] In the technical solution of this application, with the cooperation of the nested structure of the first guide rail, the second guide rail and the third guide rail, the material handling equipment can realize modular motion control. The second guide rail expands the horizontal transport range, and the third guide rail independently controls the lifting and lowering, which simplifies the structure of the material handling equipment. Moreover, the first guide rail, the second guide rail and the third guide rail can be maintained independently, which reduces the difficulty of repair / maintenance.

[0012] In one possible implementation, the vacuum defoaming system further includes a lifting device located on one side of the feed inlet of the vacuum pressurizing device, and the lifting device and the vacuum pressurizing device are distributed along the second direction. The lifting device includes a base and a support portion that are movably connected, and the support portion is capable of moving relative to the base along the third direction.

[0013] In the technical solution of this application, the lifting device can serve as a temporary buffer area to coordinate the production cycle differences between the material handling device and the vacuum pressurizing device, such as temporarily storing the load when the vacuum pressurizing device is not ready or is working; since the bearing part can move relative to the base in a third direction, the bearing part can match the height of the load carried by the material handling part, reducing the energy consumption of the material handling part in the third direction, making the picking and placing of the material handling part more stable and reliable; at the same time, the bearing part can also avoid the feeding point of the vacuum pressurizing device by its own movement in the third direction, avoiding affecting the opening and closing operation of the vacuum pressurizing device.

[0014] In one possible implementation, the support portion includes a support plate and a support member that are movably connected, the support plate being movable relative to the support member in the second direction.

[0015] In the technical solution of this application, since the support plate can move relative to the support member along the second direction, and the lifting device and the vacuum pressurizing device are arranged along the second direction, the support plate can move closer to or further away from the feed port of the vacuum pressurizing device along the second direction. This facilitates the material handling device in placing the load into or removing the load from the vacuum pressurizing device, reducing the energy consumption of the material handling part in the second direction. Furthermore, the support plate can move relative to the base in both the third and second directions, and the lifting device constitutes a two-degree-of-freedom motion mechanism, improving the accuracy of the load docking with the vacuum pressurizing device.

[0016] In one possible implementation, the support plate has a plurality of placement positions, each of which is used to hold one of the loads.

[0017] In the technical solution of this application, a multi-station buffer design is formed by setting multiple placement positions, which allows multiple loads to be processed at one time. This enables multiple loads to be fed in batches. That is, after multiple placement positions have all loads, all loads are put into the vacuum pressurization equipment as the same batch and vacuum degassing is performed at the same time, which improves the vacuum degassing efficiency of the vacuum degassing system for batch materials.

[0018] In one possible implementation, the vacuum pressurization device includes a housing, a door, and a door opening / closing assembly. The housing has a receiving cavity, the door is movably connected to the housing, and the door opening / closing assembly is drive-connected to the door.

[0019] In the technical solution of this application, the door opening and closing assembly realizes the automated opening and closing of the receiving cavity of the vacuum pressurization equipment, reducing manual operation and lowering labor costs.

[0020] In one possible implementation, the off-line device includes an interconnected feeding section, a first conveying section, and a first lifting section. The first conveying section has a first channel and a second channel distributed along the third direction, and the first lifting section has a first platform capable of moving along the third direction.

[0021] In the technical solution of this application, the first channel, the second channel and the first lifting unit realize the material inlet and outlet flow line separation design of the off-line equipment, improve logistics efficiency and the buffering capacity of the off-line equipment, and reduce the possibility of blockage of the vacuum defoaming system production line.

[0022] In one possible implementation, the online device includes an interconnected discharge section, a second conveying section, and a second lifting section. The second conveying section has a third channel and a fourth channel distributed along the third direction, and the second lifting section has a second platform capable of moving along the third direction.

[0023] In the technical solution of this application, the third channel, the fourth channel and the second lifting unit realize the material inlet and outlet flow line separation design of the online equipment, improve logistics efficiency and buffer capacity of the online equipment, and reduce the possibility of blockage of the vacuum defoaming system production line.

[0024] In one possible implementation, the material carrier has multiple positioning holes, and the material picking part has multiple picking rods, which can be matched one-to-one with the multiple positioning holes.

[0025] In the technical solution of this application, by setting the loading component and the picking part to a column-hole fit, the fit precision between the loading component and the picking part is improved, which can realize the non-offset handling of the loading component, avoid the tilting of the loading component and the material, and improve the handling stability; at the same time, it reduces mechanical positioning error, improves the repeatability accuracy between the loading component and the picking part, and reduces the damage rate of the material.

[0026] In one possible implementation, there are multiple material-taking units, which are distributed along the first direction.

[0027] In the technical solution of this application, by setting up multiple material handling units distributed along the production line direction, parallel handling function is realized, which can simultaneously handle multiple loads, improve the material handling efficiency, make the vacuum defoaming system more flexible, and help reduce equipment waiting time and improve operation efficiency.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions.

[0049] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0050] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0051] In electronic packaging processes, chips in PCBs (Printed Circuit Boards) typically require underfill adhesive. This underfill adhesive is used to fill the tiny gaps between the chip and the substrate, fixing the chip to the substrate and preventing it from falling off during subsequent processing or use.

[0052] After applying the underfill adhesive, a defoaming process is usually required to prevent air bubbles in the underfill adhesive from causing stress concentration in the encapsulation layer, leading to cracking and damage to circuit connections. In related technologies, vacuum pressure defoaming equipment is mostly a tank structure, while PCB production lines use an assembly line method for transportation, making the connection between the two difficult. Therefore, the loading and unloading of vacuum pressure defoaming equipment is mostly done manually, which is not only inefficient and costly in terms of labor, but also unstable and may cause product tilting, affecting product quality.

[0053] To address the aforementioned problems, this application provides a vacuum degassing system that can improve material handling efficiency and stability.

[0054] like Figure 1 As shown, the vacuum degassing system provided in this application embodiment includes an offline device 1, a vacuum pressurizing device 2, an online device 3, a material handling device 4, and a material carrier 5.

[0055] The offline device 1, vacuum pressurizing device 2, and online device 3 are arranged along the first direction X, and the material carrier 5 is used to carry the material. The material handling device 4 includes a first guide rail 41 and a material handling part 44. The first guide rail 41 extends along the first direction X, and the material handling part 44 is movably connected to the first guide rail 41 and can move along the first direction X, the second direction Y, and the third direction Z. The material handling part 44 is used to transport the material carrier 5, wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0056] For example, the materials include a product and a carrier for loading the product; the product may be a PCB board. The carrier 5 can carry multiple materials, for example... Figure 10 As shown, the material carrier 5 has fifteen spaced-apart storage slots 51, which can hold fifteen materials.

[0057] The off-line device 1 is used to load untreated material from the production line into the carrier 5, and the on-line device 3 is used to return the treated material to the production line. Optionally, the off-line device 1 and the on-line device 3 can load or unload materials using a handling mechanism such as a robotic arm, or they can be loaded or unloaded manually.

[0058] Vacuum pressurization equipment 2 is used to perform vacuum pressurization degassing treatment on materials. By controlling parameters such as time, temperature, pressure, and vacuum, air bubbles in the bottom filler are expelled, and the bottom filler is cured. Vacuum pressurization equipment 2 can be one or more, for example... Figure 1 As shown, there are two vacuum pressurizing devices 2, which are distributed at intervals along the first direction X, and can perform defoaming treatment simultaneously, thereby improving the processing efficiency of materials.

[0059] The first guide rail 41 guides the material handling unit 44 to move along the first direction X. The material handling device 4 also includes multiple driving devices, which drive the material handling unit 44 to move along the first direction X, the second direction Y, or the third direction Z, respectively, so that the material handling unit 44 can flexibly pick up and place the load 5 in each direction. The driving devices can be power components such as cylinders, hydraulic cylinders, motors, and electric push rods. The first direction X and the second direction Y are both parallel to the horizontal direction, and the third direction Z is the vertical direction, that is, the height direction of each device in the vacuum defoaming system.

[0060] For example, the control method for the operating state of the drive device includes one or more of the following: manual control, electromagnetic relay control, controller control, and intelligent algorithm control. For instance, the drive device is connected to the controller, and the controller automatically adjusts the operating state of the drive device through PID control, fuzzy control, etc., according to the preset control program and / or the signals collected by the sensor, thereby reducing manual intervention and improving the automation and intelligence of the vacuum defoaming system.

[0061] Optionally, the material handling device 4 is a gantry truss. For example... Figure 2 As shown, the first guide rail 41 extends along the first direction X and is located on top of the lowering equipment 1, the vacuum pressurizing equipment 2, and the upper equipment 3, and spans across the lowering equipment 1, the vacuum pressurizing equipment 2, and the upper equipment 3. The material handling unit 44 moves along the first direction X under the guidance of the first guide rail 41 and can move to the lowering equipment 1, the vacuum pressurizing equipment 2, and the upper equipment 3 to transport and convey the load 5, thereby improving the automation level of material handling and saving a lot of manpower.

[0062] When the material handling unit 44 moves along the second direction Y, it can more easily feed the material-loaded component 5 into the vacuum pressurizing device 2 or remove the material-loaded component 5 from the vacuum pressurizing device 2. When the material handling unit 44 moves along the third direction Z, it can adjust the height of the material-loaded component 5, and pick up and place the material-loaded component 5 more stably.

[0063] The vacuum degassing system provided in this application embodiment has a first guide rail 41 extending along the first direction X for the material handling device 4, and the material handling part 44 is movably connected to the first guide rail 41. Therefore, the material handling part 44 can move and transport the loading component 5 along the first direction X between the offline device 1, the vacuum pressurizing device 2, and the online device 3. Since the material handling part 44 can also move along the second direction Y and the third direction Z, it can replace manual operation, flexibly pick up and place the loading component 5, realize automated handling of materials in the loading component 5, reduce labor costs, improve material handling efficiency, increase production capacity, and improve handling stability, avoid material tilting, and improve product yield. The setting of the material handling device 4 improves the automation and intelligence of the vacuum degassing system, provides a foundation for intelligent production, and enables the vacuum degassing system to be applied to smart factories.

[0064] In some embodiments, the material carrier 5 has a plurality of positioning holes 52, and the material taking part 44 has a plurality of material taking rods 441, which can be matched one-to-one with the plurality of positioning holes 52.

[0065] like Figure 4 and 10 As shown, the top side of the loading component 5 has two positioning holes 52, and the picking part 44 has two picking rods 441. The two picking rods 441 are distributed at intervals along the first direction X, and both picking rods 441 extend along the second direction Y. The distance between the two picking rods 441 is equal to the distance between the two positioning holes 52, so that the two picking rods 441 can be inserted into the two positioning holes 52 one by one, which facilitates the handling of the loading component 5.

[0066] The positioning hole 52 can be round, rectangular, elliptical or other shapes. The cross-sectional shape of the material taking rod 441 can be the same as or different from the positioning hole 52. This application does not make specific limitations on this.

[0067] In this embodiment, by setting the loading component 5 and the picking part 44 to be in a column-hole fit, the fit precision between the loading component 5 and the picking part 44 is improved, enabling the loading component 5 to be transported without offset, avoiding tilting of the loading component 5 and the material, and improving the stability of the transport; at the same time, it reduces mechanical positioning error, improves the repeatability of the positioning between the loading component 5 and the picking part 44, and reduces the damage rate of the material.

[0068] The number of material picking units 44 can be one or more. For example, in some embodiments, there are multiple material picking units 44, which are distributed along the first direction X.

[0069] Optionally, the multiple material handling units 44 can be driven by different drive devices to achieve movement, and each material handling unit 44 can be controlled independently to achieve asynchronous operation. For example, when one material handling unit 44 is under maintenance, the other material handling units 44 can still operate normally.

[0070] Optionally, multiple picking units 44 can be equipped with picking rods 441 of different shapes or sizes to adapt to different types of material carriers 5 and improve the applicability of the picking equipment 4.

[0071] In this embodiment, by setting up multiple material handling units 44 distributed along the production line direction, the parallel handling function is realized, which can simultaneously handle multiple material carriers 5, improve the material handling efficiency, make the vacuum defoaming system more flexible, and help reduce equipment waiting time and improve work efficiency.

[0072] In some embodiments, such as Figure 3 and Figure 4 As shown, the material handling device 4 also includes a second guide rail section 42 and a third guide rail section 43. The second guide rail section 42 is movably connected to the first guide rail section 41 and the third guide rail section 43 respectively. The second guide rail section 42 extends along the second direction Y, and the third guide rail section 43 extends along the third direction Z. The material handling section 44 is movably installed on the third guide rail section 43.

[0073] The second guide rail 42 can move along the first direction X on the first guide rail 41, the third guide rail 43 can move along the second direction Y on the second guide rail 42, and the material picking unit 44 can move along the third direction Z on the third guide rail. The second guide rail 42, the third guide rail 43, and the material picking unit 44 can be driven independently by different driving devices. The sliding connection between the first guide rail 41 and the second guide rail 42, between the second guide rail 42 and the third guide rail 43, and between the third guide rail 43 and the material picking unit 44 can be achieved by linear guide rails, sliders, gear meshing, or any sliding connection method in the prior art. This application does not make specific limitations in this regard.

[0074] With the cooperation of the nested structure of the first guide rail section 41, the second guide rail section 42 and the third guide rail section 43, the material handling device 4 can realize modular motion control. The horizontal transport range is expanded by the second guide rail section 42 and the lifting is independently controlled by the third guide rail section 43, which simplifies the structure of the material handling device 4. Moreover, the first guide rail section 41, the second guide rail section 42 and the third guide rail section 43 can be maintained independently, which reduces the difficulty of maintenance.

[0075] In some embodiments, the vacuum degassing system further includes a lifting device 6, which is disposed on the side where the feed port of the vacuum pressurizing device 2 is located, and the lifting device 6 and the vacuum pressurizing device 2 are distributed along the second direction Y. The lifting device 6 includes a base 61 and a support part 62 that are movably connected, and the support part 62 can move relative to the base 61 along the third direction Z.

[0076] The feed inlet of the vacuum pressurizing device 2 is located on one side of the vacuum pressurizing device 2 in the second direction Y, and the lifting device 6 is adjacent to the vacuum pressurizing device 2 and close to the feed inlet of the vacuum pressurizing device 2.

[0077] The lifting device 6 is used to receive the material 5 conveyed by the material handling device 4 via the bearing part 62, and to cooperate with the loading and unloading operations of the vacuum pressurizing device 2. The bearing part 62 and the base 61 can be slidably connected by a linear guide rail, a slider, gear meshing, or any of the existing sliding connection methods. The bearing part 62 moves up and down relative to the base 61 in the third direction Z under the drive of the driving device.

[0078] In this embodiment, the lifting device 6 can serve as a temporary buffer area to coordinate the production cycle differences between the material handling device 4 and the vacuum pressurizing device 2, for example, to temporarily store the load 5 when the vacuum pressurizing device 2 is not ready or is working; since the bearing part 62 can move relative to the base 61 in the third direction Z, the bearing part 62 can match the height of the load 5 carried by the material handling part 44, reducing the energy consumption of the material handling part 44 in the third direction Z, making the picking and placing of the material handling part 44 more stable and reliable; at the same time, the bearing part 62 can also avoid the feeding point of the vacuum pressurizing device 2 by its own movement in the third direction Z, so as to avoid affecting the opening and closing operation of the vacuum pressurizing device 2.

[0079] In some embodiments, such as Figure 5 As shown, the support portion 62 includes a support plate 621 and a support member 622 that are movably connected. The support plate 621 is capable of moving relative to the support member 622 in the second direction Y.

[0080] For example, the support member 622 can move relative to the base 61 in the third direction Z under the drive of the drive device, and the bearing plate 621 can move relative to the support member 622 in the second direction Y under the drive of the drive device, and the bearing plate 621 directly supports the material member 5.

[0081] Since the support plate 621 can move relative to the support member 622 along the second direction Y, and the lifting device 6 and the vacuum pressurizing device 2 are arranged along the second direction Y, the support plate 621 can move closer to or further away from the feed port of the vacuum pressurizing device 2 along the second direction Y, which makes it convenient for the material handling device 4 to put the material 5 into the vacuum pressurizing device 2 or to take the material 5 out of the vacuum pressurizing device 2, thereby reducing the energy consumption of the material handling part 44 in the second direction Y.

[0082] Furthermore, the support plate 621 can move relative to the base 61 in the third direction Z and also in the second direction Y. The lifting device 6 constitutes a two-degree-of-freedom motion mechanism, which improves the accuracy of docking the material component 5 with the vacuum pressurization device 2.

[0083] In some embodiments, the support plate 621 has a plurality of placement positions 6211, each placement position 6211 being used to support a material carrier 5.

[0084] like Figure 5 As shown, the support plate 621 has four placement positions 6211, which can support four material carriers 5.

[0085] In this embodiment, by setting multiple placement positions 6211, a multi-station buffer design is formed, which allows multiple material carriers 5 to be processed at one time. This enables multiple material carriers 5 to be fed in batches. That is, after multiple placement positions 6211 have all carried material carriers 5, all material carriers 5 are put into the vacuum pressurization equipment 2 as the same batch and vacuum degassing is performed simultaneously, which improves the vacuum degassing efficiency of the vacuum degassing system for batch materials.

[0086] In some embodiments, such as Figure 8 and Figure 9 As shown, the vacuum pressurization device 2 includes a housing 21, a door 22, and a door opening and closing assembly 23. The housing 21 has a receiving cavity 211. The door 22 is movably connected to the housing 21. The door opening and closing assembly 23 is drivenly connected to the door 22. The door opening and closing assembly 23 is used to drive the door 22, thereby opening or closing the receiving cavity 211.

[0087] The receiving cavity 211 is used to receive the loading component 5 and the material. The vacuum pressurization and defoaming operation of the vacuum pressurization equipment 2 needs to be carried out with the door 22 closed.

[0088] For example, the door opening and closing assembly 23 is disposed in the housing 21. The door opening and closing assembly 23 includes drive devices such as electric push rod, cylinder, hydraulic cylinder, and motor, as well as transmission devices such as connecting rod and gear connected to the door 22. The drive device is connected to the transmission device, and the power of the drive device is transmitted to the door 22 through the transmission device to realize the automatic opening or closing of the door 22.

[0089] Optionally, the drive unit of the door opening and closing assembly 23 is directly or indirectly connected to the drive unit of the material handling device 4 and the drive unit of the lifting device 6, thereby enabling continuous operation of the vacuum defoaming system, reducing production cycle time, and improving work efficiency. After the door opening and closing assembly 23 controls the door body 22 to open, the material handling device 4 transports the material 5 on the support plate 621 into the receiving cavity 211, or removes the material 5 from the receiving cavity 211.

[0090] For example, the operation flow of the vacuum pressurizing device 2 includes: after the vacuum pressurizing device 2 completes the vacuum pressurizing and degassing operation, the door opening and closing assembly 23 controls the door 22 to open; the material picking part 44 of the material picking device 4 moves to the gripping position and removes the material 5 in the receiving cavity 211; the material picking device 4 transports all the material and material 5 that have undergone the vacuum pressurizing and degassing operation to the upper line device 3, and then moves to the lower line device 1, and transports the material and material 5 that have not undergone the vacuum pressurizing and degassing operation to the placement position 6211 of the lifting device 6; the lifting device 6 adjusts the position of the bearing plate 621 along the third direction Z to the loading position, and the material picking device 4 transports the material 5 on the placement position 6211 into the receiving cavity 211; the lifting device 6 adjusts the position of the bearing plate 621 along the third direction Z to the clearance position, the door opening and closing assembly 23 controls the door 22 to close, the vacuum pressurizing device 2 performs the vacuum pressurizing and degassing operation, and after completion, enters the next cycle.

[0091] In this embodiment, the door opening and closing assembly 23 enables the automated opening and closing of the receiving cavity 211 of the vacuum pressurization device 2, reducing manual operation and lowering labor costs.

[0092] In some embodiments, the offline device 1 includes a feeding section 11, a first conveying section 12 and a first lifting section 13 that are interconnected. The feeding section 11 and the first conveying section 12 each have a first channel 121 and a second channel 122 distributed along a third direction Z. The first lifting section 13 has a first platform 131 that is capable of moving along a third direction Z.

[0093] The feeding section 11 is used to stop the material on the production line and fill the empty loading unit 5 with the material. The feeding section 11 can be a material unloading device for a production line in the prior art. The first conveying section 12 is used to transport the loading unit 5 between the feeding section 11 and the first lifting section 13. The first lifting section 13 can connect to the first channel 121 and the second channel 122 respectively through the movement of the first platform 131 in the third direction Z, thereby receiving or outputting the loading unit 5.

[0094] like Figure 6 As shown, the first channel 121 is located above the second channel 122. Both the first channel 121 and the second channel 122 are equipped with linear automatic conveying structures such as guide rails, and both the first channel 121 and the second channel 122 are capable of transporting the load 5. Optionally, the first channel 121 is used to transport a full load 5, and the second channel 122 is used to transport an empty load 5. Figure 6 The solid arrow in the image indicates the direction of movement of the fully loaded loading component 5 in the first channel 121. Figure 6 The dashed arrow in the image shows the direction of movement of the empty loading component 5 in the second channel 122.

[0095] By setting up the first channel 121, the second channel 122 and the first lifting part 13, the material inlet and outlet flow lines of the off-line equipment 1 are separated, which improves logistics efficiency and the buffering capacity of the off-line equipment 1, and reduces the possibility of blockage in the vacuum defoaming system production line.

[0096] For example, the operation flow of the off-line device 1 includes: the material on the production line is moved to the unloading position of the feeding section 11, and the feeding section 11 stops the material; the feeding section 11 fills the material into the loading component 5; after the loading component 5 is full, it is transported along the first channel 121 to the first lifting section 13, and the picking device 4 transports the full loading component 5 to the lifting device 6; the picking device 4 transports the empty loading component 5 at the on-line device 3 to the first lifting section 13, the first lifting section 13 descends, and the empty loading component 5 is conveyed along the second channel 122, so that the empty loading component 5 flows back along the second channel 122.

[0097] In some embodiments, the online device 3 includes an interconnected discharge section 31, a second conveying section 32, and a second lifting section 33. The second conveying section 32 has a third channel 321 and a fourth channel 322 distributed along the third direction Z. The second lifting section 33 has a second platform 331 capable of moving along the third direction Z.

[0098] The discharge section 31 is used to place the material that has undergone vacuum degassing treatment in the loading component 5 into the production line. The discharge section 31 can be a material feeding device for an assembly line in the prior art. The second conveying section 32 is used to transport the loading component 5 between the discharge section 31 and the second lifting section 33. The second lifting section 33 can connect to the third channel 321 and the fourth channel 322 respectively through the movement of the second platform 331 in the third direction Z, thereby receiving or outputting the loading component 5.

[0099] like Figure 7 As shown, the third channel 321 is located above the fourth channel 322. Both the third channel 321 and the fourth channel 322 are equipped with linear automatic conveying structures such as guide rails, and both the third channel 321 and the fourth channel 322 are capable of transporting the load 5. Optionally, the third channel 321 is used to transport the load 5 when it is full, and the fourth channel 322 is used to transport the load 5 when it is empty. Figure 7 The solid arrow in the image indicates the direction of movement of the fully loaded material carrier 5 in the third channel 321. Figure 6 The dashed arrows in the diagram indicate the direction of movement of the empty loading component 5 in the fourth channel 322.

[0100] By setting up the third channel 321, the fourth channel 322, and the second lifting unit 33, the material inlet and outlet flow lines of the online equipment 3 are separated, which improves logistics efficiency and the buffering capacity of the online equipment 3, and reduces the possibility of blockage in the vacuum defoaming system production line.

[0101] For example, the operation flow of the online device 3 includes: the material handling device 4 takes out the loading component 5 from the receiving cavity 211 of the vacuum pressurizing device 2 and transports it to the second lifting unit 33; the second lifting unit 33 transports the full loading component 5 to the third channel 321; the full loading component 5 in the third channel 321 moves to the discharge unit 31, and the discharge unit 31 takes out the material in the loading component 5 and places it into the production line; after all the material in the loading component 5 is placed into the production line, the material handling device 4 or other handling mechanism (such as a robot, robotic arm, etc.) transports the empty loading component 5 to the fourth channel 322, and the empty loading component 5 flows back to the second lifting unit 33 through the fourth channel 322; the second platform 331 of the second lifting unit 33 rises, and the material handling device 4 takes away the empty loading component 5 and transports it to the offline device 1.
