Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a metal cabinet assembly processing device. Background Technology

[0002] In the industrial manufacturing sector, metal cabinets such as server racks, power control cabinets, and special chemical containers often require integrated linear closed liquid flow channel systems for efficient heat dissipation and cooling or safe transport of chemical media. These flow channels are generally designed to be linear, mainly due to the feasibility of traditional stamping-welding processes. Simple linear molds are the lowest cost and easiest to manufacture, and long, straight welds are the easiest to automate, ensuring reliable sealing and controlling costs. The traditional manufacturing method is usually as follows: first, a half-width linear flow channel groove is processed from a metal sheet by stamping; then, the two metal sheets are joined together and their outer perimeter is welded to form a sealed linear pipe, thus producing an independent cabinet component or flow channel panel, which is then assembled into the final metal cabinet as a core component.

[0003] However, the above methods have revealed a series of problems that urgently need to be solved in modern industrial applications: when the flow channel is used for water cooling, the cooling medium is in long-term contact with the inner metal wall, which can easily cause electrochemical corrosion and scale formation. Corrosion can directly lead to leakage risks, and the attached scale itself acts as a thermal resistance layer, which will cause the heat dissipation efficiency to decrease significantly over time. When the flow channel is used to transport corrosive chemicals, the problem of the medium eroding the metal and the possible metal ion pollution is even more serious, which directly affects product purity and system safety.

[0004] Currently, the industry commonly applies an anti-corrosion coating or attaches a flexible protective tube to the inner wall of the formed flow channel manually. This method has two major drawbacks:

[0005] The problem of "weak interface": The protective layer relies solely on the chemical adhesion of the adhesive to bond with the smooth metal surface, which is a "surface bond" with limited strength. Under long-term thermal cycling, fluid pressure pulsation and media penetration, stress concentration is easily generated at the interface, leading to blistering, peeling or even complete detachment of the coating or lining.

[0006] The problem of "incomplete fit": For functional channels with complex three-dimensional microstructures designed to enhance heat dissipation or improve flow field, existing manual or simple mechanical application methods are completely unable to achieve a complete fit of the flexible protective layer without bubbles or gaps. These unfilled gaps not only become the starting point of corrosion, but also form local "thermal insulation zones" in heat dissipation scenarios, which seriously negates the structural efforts made by the channel itself to improve performance.

[0007] Existing technologies treat flow channel structure design, molding and manufacturing, and internal surface protection as separate processes. This separation leads to low production efficiency, excessive reliance on manual operation for quality, and poor consistency. More importantly, the functional structural design of the flow channel cannot be effectively utilized and enhanced in subsequent protective processes. For example, rib-shaped recesses designed to improve heat dissipation become dead corners for accumulating bubbles and corrosive media because the protective layer cannot fill them. The structural advantages are transformed into performance shortcomings.

[0008] The core dilemma of existing technologies lies in the lack of a dedicated device that can integrate the "functional structural design" of metal flow channels with "high-performance protective lining" in an automated manner. This device can not only achieve automated, high-quality, and full-fitting of the protective layer in complex internal cavities, but also actively utilize and enhance the microstructure of the flow channels themselves to achieve synergistic improvements in heat dissipation (or flow control), corrosion prevention, and long-term mechanical reliability, thereby meeting the increasingly stringent requirements of high-end equipment for the performance of metal cabinets. Summary of the Invention

A plurality of feeding electric push rods that match the protective tube are fixedly connected to one end of the support frame, and a cutting feeding ring is fixedly connected to the output end of the feeding electric push rod.

[0014] Preferably, the inner wall of the cutting and feeding ring is fixedly connected with a plurality of evenly distributed adsorption blocks, and the inner wall of the cutting and feeding ring is embedded with an electric slide rail. The electric slide rail is located on the side away from the support frame, and an electric slider is installed inside the electric slide rail. An electric cutting tool is installed at one end of the electric slider.

[0015] Preferably, the adsorption assembly includes an adsorption spray box, a linear moving mechanism is installed on the top of the attachment stage, a movable electric actuator is fixedly connected to the output end of the linear moving mechanism, the output end of the movable electric actuator is fixedly connected to the adsorption spray box, a negative pressure vacuum pump and a storage box are provided inside the adsorption spray box, an adhesive is provided inside the storage box, and a gear pump is installed inside the storage box.

[0016] Preferably, the adsorption spray pipe consists of an outer adsorption pipe disposed on the outside and an inner spray pipe disposed on the inside. The outer adsorption pipe is connected to a negative pressure vacuum pump, and the inner spray pipe is connected to a gear pump. A first annular spray head is installed around the inner spray pipe, and an insertion rod is installed at one end of the inner spray pipe. A fixing groove is provided on the insertion rod.

[0017] Preferably, the bonding and fixing assembly includes a bonding and fixing box, a reinforcing box installed inside the bonding and fixing box, a reinforcing agent and a spray pump installed inside the reinforcing box, an extrusion box installed inside the bonding and fixing box, a curing liquid and a high-temperature reciprocating pump installed inside the extrusion box, multiple placement grooves are provided on the bonding and fixing box, and a placement rack is installed in the placement grooves. A damper is installed at one end of the placement rack, and an integrated functional tube is provided in the placement groove.

[0018] Preferably, the integrated functional tube is provided with a reinforcing hose and a circulating curing hose, the reinforcing hose being connected to a jet pump, and the circulating curing hose being connected to a high-temperature reciprocating pump.

[0019] Preferably, the reinforcing component includes a second annular spray head and a compression balloon.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) This solution uses the extrusion protrusion in the stamping mechanism to pre-set uniformly distributed extrusion concave points during the flow channel forming. Subsequently, in the bonding and fixing assembly, the extrusion balloon expands under the drive of high temperature heat transfer oil, applies hot pressure to the protective tube, causes its material to undergo plastic deformation and fully embeds into the concave points, changes the interface bonding mechanism, transforms the traditional two-dimensional "surface bonding" into three-dimensional "body embedding", enhances the bonding strength and anti-peeling ability, and solves the interface failure problem under long-term thermal cycling and pressure pulsation.

[0022] (2) This scheme adopts the "from inside to outside" force application method. Inside the flow channel, the extrusion balloon is used as a flexible force application medium. It can expand uniformly under pressure. Its shape can adapt to every contour change of the inner wall of the flow channel, ensuring that the protective tube can be subjected to radial pressure on the curved surface and concave point inside the flow channel under the action of hot pressure. This allows it to be tightly compacted and fill the gaps, realizing the fit between the protective layer and the complex inner surface, preventing corrosion hazards and the occurrence and generation of thermal insulation zones, so that the function of the reinforcing structure of the flow channel itself can be brought into play.

[0023] (3) The present invention integrates the stamping table, the integrated component and the attachment table into an automatic line. From stamping the metal plate with concave points, applying glue and welding, to the automatic sleeve cutting of the protective tube, the ring spraying of the adhesive, and finally the hot pressing curing and reinforcement coating, all processes are automatically completed in a continuous system. This integrated structure reduces the handling, waiting and dependence on skilled workers between processes, and realizes fully automatic, high-precision and high-consistency production from metal plates to high-quality flow channel panels with completed inner lining. Not only is the production efficiency greatly improved, but more importantly, it ensures that the product has stable protective performance and meets the batch requirements of high-end equipment for the reliability of key components.

[0037] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0038] like Figure 1 And such as Figures 7 to 9 As shown in the figure, an embodiment of the present invention provides a metal cabinet assembly processing device, including: an integration component 2 and an attachment platform 3. The integration component 2 includes a flip coating mechanism and a welding mechanism. The flip coating mechanism is used to coat and bond a pair of stamped metal plates 15 with adhesive. The welding mechanism is used to weld the bonding seam surrounding the bonded pair of metal plates 15. The top of the attachment platform 3 is provided with a sleeve cutting component 4, an adsorption component 5 and a bonding fixing component 6. The sleeve cutting component 4 is provided with a protective tube 44. The adsorption component 5 is provided with a plurality of evenly distributed adsorption spray pipes 52. The bonding fixing component 6 is provided with a reinforcement component 7 that matches the adsorption spray pipes 52. The reinforcement component 7 is used to squeeze and solidify the protective tube 44 so that the protective tube 44 is tightly bonded to a pair of flow channels.

[0039] Among them, the integrated component 2 is the core module of this device that combines and welds two independent metal plates 15 into a complete flow channel panel, and the flip coating mechanism is a programmable multi-axis robotic arm or flip frame with a special gripper at its end.

[0040] The flip coating mechanism first precisely picks up a metal plate 15 that has been stamped with indentations from the upstream conveyor track 11 and transports it to a fixed coating station.

[0041] At the coating station, there is a set of precision dispensing heads or roller coating devices. According to a preset program, the device applies a uniform and quantitative layer of structural adhesive, usually epoxy or acrylic two-component adhesive, to the flow channel groove plane of the metal plate 15, i.e. the surface to be bonded.

[0042] After the adhesive is applied, the flipping mechanism drives the clamp to precisely flip the metal plate 15 180 degrees. At the same time, another metal plate 15 without adhesive is transported to the bonding and positioning platform below via parallel tracks.

[0043] The flipping mechanism precisely aligns the adhesive plate with the substrate below, usually relying on positioning pins or a vision system on the platform. Then, it presses down smoothly to align and press the semi-circular flow channels of the two metal plates 15 that have been stamped twice, forming a complete circular flow channel prototype with concave dots. The adhesive initially fills the interface under pressure.

[0044] The welding mechanism is located behind or around the bonding station and is used to weld the components after initial bonding, including:

[0045] Depending on the metal material, such as stainless steel or aluminum alloy, TIG (tungsten inert gas) welding or laser welding machines are selected. The welding torch is mounted on a multi-axis linkage welding torch arm.

[0046] The welding assembly has a pre-set closed rectangle or customized welding path around its perimeter. The welding gun arm moves along this path to perform continuous and uniform welding on the outer ring of the joint formed by the butt joint of the two metal plates 15.

[0047] The welding process is carried out under the protection of an inert gas such as argon to prevent oxidation. After welding is completed, an automatic slag removal or grinding unit can be integrated to perform preliminary treatment on the weld and ensure that the flow channel panel has a smooth appearance and is free of foreign objects in subsequent processes.

[0048] The flip coating mechanism and welding mechanism are existing technologies and will not be described in detail here.

[0049] The sleeve cutting component 4, the adsorption component 5 and the bonding and fixing component 6 on the attachment platform 3 work together to realize a fully automatic flow channel lining process: First, the sleeve cutting component 4 automatically sleeves and cuts the protective tube 44 onto the adsorption spray tube 52.

[0050] Subsequently, the adsorption component 5, carrying the protective tube, is inserted into the flow channel. During its movement, the adhesive is evenly sprayed onto the inner wall of the flow channel through the first annular spray head 53. Then, the protective tube 44 is released to allow it to initially adhere. Finally, the adsorption spray tube 52 automatically docks and locks with the reinforcement 7 of the bonding and fixing component 6. The compression balloon 73 at the front end of the reinforcement 7 expands inside the flow channel, applying heat and pressure to the protective tube 44, causing it to plastically deform and tightly embed into the concave point of the flow channel, while simultaneously curing the adhesive. This method solves the problems of "weak interface" and "incomplete adhesion" in traditional manual lining, achieving high-quality, high-efficiency, and fully automated preparation of the inner protective layer of the flow channel.

[0051] like Figures 1 to 2 As shown, the combined processing device also includes a stamping table 1, a transfer track 11 is installed on the top of the stamping table 1, a metal plate 15 is arranged in the transfer track 11, and a stamping mechanism is provided on the top of the stamping table 1. The stamping mechanism is used to perform secondary stamping on the metal plate 15 to open multiple flow channel recesses.

[0052] The stamping mechanism includes a hydraulic cylinder 12, a die-casting top plate 14 is installed at the output end of the hydraulic cylinder 12, a die-casting bottom plate 13 is installed at the top of the stamping table 1 and below the die-casting top plate 14, a plurality of evenly distributed stamping half rings are fixedly connected to the bottom end of the die-casting top plate 14, a plurality of evenly distributed extrusion protrusions are installed around the stamping half rings, and a stamping groove matching the stamping half rings is opened on the die-casting bottom plate 13.

[0053] The stamping mechanism in this invention is the foundation and primary link in constructing a high-performance composite flow channel. Its design principle and function directly determine the core performance of the final product. The mechanism is mainly composed of a hydraulic cylinder 12, a die-casting top plate 14, and a die-casting bottom plate 13 working together.

[0054] The transfer track 11 precisely transports the metal plate 15 to the pre-set stamping groove on the die-casting base plate 13. It should be noted that the metal plate 15 has already undergone the first stamping, forming the prototype of a semi-cylindrical flow channel.

[0055] Subsequently, the hydraulic cylinder 12 is activated, driving the die-casting top plate 14 to move downward. Multiple stamped semi-rings fixed to the bottom end of the die-casting top plate 14 precisely align with the stamped grooves on the die-casting bottom plate 13, and also match the semi-cylindrical flow channel prototype formed by the first stamping of the metal plate 15.

[0056] During the second stamping process, specific extrusion protrusions are evenly distributed on the outer surface of each stamping half-ring. During the second stamping process, these protrusions will simultaneously form corresponding, evenly distributed extrusion indentations on the inner surface of the flow channel prototype that forms the semi-cylinder.

[0057] The purpose of this design is to solve two problems in the traditional smooth flow channel manufacturing process: the bottleneck of heat dissipation efficiency and the insufficient adhesion of the protective layer.

[0058] The resulting array of extruded concave points is essentially an extended heat exchange surface structure. Compared with traditional smooth inner walls, it significantly increases the effective contact area between the inner wall of the flow channel and the internal flow medium, thereby enhancing the overall heat dissipation capacity of the metal cabinet from the source.

[0059] The resulting extrusion indentations are also mechanically interlocked anchor points pre-designed for subsequent processes. When the protective tube 44 is subsequently bonded, the protective tube 44 will plastically deform under hot pressing and fully embed itself into these indentations.

[0060] The traditional, easily peelable "surface bonding" is upgraded to a robust "body bonding", which greatly enhances the bonding strength between the protective tube 44 and the metal substrate and the long-term anti-peel reliability.

[0061] It should be noted that the extrusion protrusions on the stamping semi-ring are designed as spherical or ellipsoidal crowns with gentle curvature, shallow depth, and relatively large opening diameter.

[0062] Specifically, the ratio (H / D) of the depth (H) of a single indentation to its opening diameter (D) is preferably controlled between 0.1 and 0.25.

[0063] The gentle concave shape has two advantages: First, during the hot pressing stage, when the balloon 73 is expanded, its wall material can flow more smoothly and evenly into and fill the concave space, driving the protective tube 44 material to undergo sufficient plastic deformation and completely occupy the concave, forming a perfect mechanical interlock; Second, it avoids the risk that the protective tube 44 may be overstretched or even torn at the edge of the concave due to the concave being too deep or too steep, ensuring the continuity of the liner and the reliability of the seal.

[0064] Conversely, if the concave point is designed as a deep pit with a large depth and a small opening, the wall of the compression balloon 73 will have difficulty effectively transmitting pressure to the bottom of the concave point during the expansion process. This can easily leave unfilled cavities in the concave point, resulting in poor local adhesion between the protective tube 44 and the metal substrate, which can become a potential corrosion initiation point or thermal resistance point.

[0065] In summary, this stamping mechanism integrates structural design, functional pre-setting, and process pre-setting. By introducing the functional structure of "extrusion concave points," it successfully integrates the requirements for heat dissipation optimization and interface enhancement into the initial stage of manufacturing, laying a crucial physical foundation for producing high-performance, long-life composite flow channel metal cabinets.

[0066] like Figures 5 to 6 As shown, the cutting assembly 4 includes a support frame 41. The bottom end of the support frame 41 is connected to the top end of the attachment platform 3. A plurality of evenly distributed support plates 42 are fixedly connected to the top end of the support frame 41. A pair of support plates 42 are rotatably connected to one end of each other. A protective tube 44 is arranged around the outside of the placement ring 43. A plurality of feeding electric push rods 45 that match the protective tube 44 are fixedly connected to one end of the support frame 41. A cutting feeding ring 46 is fixedly connected to the output end of the feeding electric push rod 45.

[0067] Multiple evenly distributed adsorption blocks 47 are fixedly connected to the inner wall of the cutting and feeding ring 46, and an electric slide rail is embedded in the inner wall of the cutting and feeding ring 46. The electric slide rail is located on the side away from the support frame 41, and an electric slider is installed in the electric slide rail. An electric cutting tool 48 is installed at one end of the electric slider.

[0068] The cutting assembly 4 is based on a support frame 41 fixed on the attachment table 3. One end of the assembly is rotatably connected to a placement ring 43 via multiple sets of support plates 42, which is used to hold the protective tube 44 and achieve continuous material feeding.

[0069] In the initial state, the adsorption spray box 51 will first adjust the multiple adsorption spray pipes 52 at its front end precisely to the preparatory position on the same axis as the cutting and feeding ring 46 through the coordinated adjustment of the linear moving mechanism 31 and the moving electric push rod 32. The linear moving mechanism 31 is a prior art, such as a moving mechanism composed of a servo motor, a reciprocating lead screw and a screw sleeve, which will not be described in detail here.

[0070] Subsequently, the cutting assembly 4 is activated, and its multiple feeding electric push rods 45 extend synchronously, pushing the cutting feeding ring 46 to move horizontally toward the already positioned adsorption spray pipe 52.

[0071] During the movement, multiple adsorption blocks 47 on the inner wall of the cutting and feeding ring 46 are energized to generate negative pressure, which pulls them out from the placement ring 43 and adsorbs the end of the protective tube 44, so that it moves forward with the cutting and feeding ring 46 and finally puts the protective tube 44 around the adsorption spray pipe 52.

[0072] After installation, the power supply to multiple adsorption blocks 47 is disconnected. A section of protective tube 44 remaining on the adsorption spray pipe 52 is then activated by the negative pressure vacuum pump, causing the adsorption spray pipe 52 to adsorb onto the protective tube 44.

[0073] Then, when the multiple feeding electric push rods 45 drive the cutting feeding ring 46 to reset to one side, the multiple adsorption blocks 47 are activated again to adsorb the protective tube 44. At this time, the electric slide rail embedded in the inner wall of the cutting feeding ring 46 drives the electric slider to drive the electric cutting cutter 48 to make a circular motion, accurately cutting the protective tube 44. After that, the feeding electric push rods 45 retract, driving the cutting feeding ring 46 and the remaining protective tube 44 to reset, preparing for the next work cycle.

[0074] like Figures 7 to 8 As shown, the adsorption assembly 5 includes an adsorption spray box 51, a linear moving mechanism 31 is installed on the top of the attachment platform 3, a moving electric push rod 32 is fixedly connected to the output end of the linear moving mechanism 31, the output end of the moving electric push rod 32 is fixedly connected to the adsorption spray box 51, a negative pressure vacuum pump and a storage box are provided inside the adsorption spray box 51, an adhesive is provided inside the storage box, and a gear pump is installed inside the storage box.

[0075] The adsorption spray pipe 52 consists of an outer adsorption pipe on the outside and an inner spray pipe on the inside. The outer adsorption pipe is connected to a negative pressure vacuum pump, and the inner spray pipe is connected to a gear pump. A first annular spray head 53 is installed around the inner spray pipe, and an insertion rod 54 is installed at one end of the inner spray pipe. A fixing groove 55 is provided on the insertion rod 54.

[0076] Among them, the adsorption component 5 is the core module of this device that realizes the dual functions of conveying and positioning the protective tube 44 and pre-treating the inner wall of the flow channel. It integrates the negative pressure adsorption and adhesive spraying functions into one, thereby creating the initial conditions for the subsequent hot pressing bonding process.

[0077] The component is based on an adsorption spray box 51, which is mounted on the attachment platform 3 via a movable electric push rod 32 and a linear moving mechanism 31, enabling it to be positioned and moved in space. The box is equipped with a negative pressure vacuum pump and a storage box for storing adhesive, and a gear pump is also provided.

[0078] The core function of the adsorption spray pipe 52 is to serve as a carrier for the protective pipe 44 and a pretreatment tool for the inner wall of the flow channel. Its unique coaxial double-pipe structure design supports a continuous automated operation cycle.

[0079] After initial installation, the outer adsorption tube generates adsorption force under the action of the negative pressure vacuum pump, causing the protective tube 44 to adhere tightly to the tube wall, forming a rigid temporary assembly. This ensures that the protective tube 44 can be accurately and stably inserted into the metal flow channel along with the adsorption spray tube 52.

[0080] During the flow channel process, the inner spray pipe on the inner side, driven by the gear pump, sprays the adhesive evenly and continuously onto the inner wall of the flow channel through the first annular spray head 53 at the end, realizing synchronous adhesive application along the entire circumference and stroke of the inner wall of the flow channel, providing a uniform bonding medium for subsequent bonding.

[0081] It should be noted that the adhesive sprayed through the first annular spray head 53 is preferably a thermosetting single-component epoxy resin structural adhesive, which is based on epoxy resin and contains latent curing agents and accelerators; the adhesive is stable at room temperature to facilitate storage and spraying.

[0082] Depending on the actual needs, different functional properties of the adhesive can be matched according to the end use, such as heat dissipation or corrosion protection. For example, thermally conductive adhesives for water-cooled pipes: thermally conductive modified epoxy resin or silicone resin; or corrosion-resistant adhesives for chemical applications: chemically resistant modified epoxy resin or fluorocarbon resin, with a curing temperature range of 120 to 180°C.

[0083] In subsequent processes, when the extrusion balloon 73 provides hot pressure at 120°C to 180°C, the adhesive rapidly undergoes a cross-linking and curing reaction, thereby firmly bonding the protective tube 44 to the inner wall of the metal flow channel with extrusion dimples.

[0084] Once the adsorption spray pipe 52 has completed the flow channel penetration and locked with the reinforcement 7, the negative pressure vacuum pump is actively disconnected. At this time, the outer adsorption pipe loses its adsorption force, and the protective pipe 44, under the elasticity of its own material, breaks free from the restraint of the adsorption spray pipe 52, restores its natural shape, and relies on its elasticity and the adhesive already applied in the flow channel to achieve initial contact and adhesion with the inner wall of the flow channel.

[0085] The adsorption spray tube 52 completes a "fixation-transportation-spraying-release" process. First, the protective tube 44 is sent into the deep flow channel, and the adhesive is sprayed simultaneously. Finally, by releasing the negative pressure, the protective tube 44 is made to adhere to the inner wall of the coated flow channel under its own elastic properties, creating perfect initial conditions for the subsequent entry of the extrusion balloon 73 and hot-press curing. The automated connection of this series of actions is the key to the high-efficiency and high-quality integrated production of this device.

[0086] Furthermore, the insertion rod 54 at the end of the adsorption spray pipe 52 and its fixing groove 55 are key automatic docking mechanisms. The purpose of its design is that after the adsorption spray pipe 52 completes the flow channel penetration, the insertion rod 54 can be accurately inserted into the corresponding insertion groove 75 of the subsequent station reinforcement 7, and mechanically locked by the fixing groove 55. At the same time, a placement rack matching the second annular spray head 72 is provided in the placement groove 62, which can place and position the second annular spray head 72, so that after insertion, it can ensure that the insertion rod 54 and the corresponding insertion groove 75 of the reinforcement 7 are aligned on the same central axis.

[0087] This design allows the adsorption spray tube 52 and the reinforcement 7 to automatically connect and combine into a longer tool, providing support for subsequent reverse heat pressing operations.

[0088] The adsorption assembly 5 integrates the fixed conveying of the protective tube 44 and the pre-treatment of the adhesive coating on the inner wall of the flow channel into the same tool and the same stroke, which greatly simplifies the mechanical structure and operation steps and improves the continuity of the process.

[0089] The insertion rod design enables the front-end execution tool to automatically connect with the back-end functional modules, realizing the modular expansion of equipment functions and the automated transmission of work processes.

[0090] Therefore, the adsorption component 5 is not only an execution unit, but also connects multiple process links such as setting, spraying, and docking. Its stable and reliable operation is the key to ensuring the automation and high precision of the entire process.

[0091] like Figures 9 to 11 As shown, the bonding and fixing assembly 6 includes a bonding and fixing box 61, a reinforcing box is installed inside the bonding and fixing box 61, a reinforcing agent and a spray pump are installed inside the reinforcing box, an extrusion box is installed inside the bonding and fixing box 61, a curing liquid and a high-temperature reciprocating pump are installed inside the extrusion box, a plurality of placement grooves 62 are provided on the bonding and fixing box 61, and a placement rack is installed in the placement groove 62. A damper is installed at one end of the placement rack, and an integrated functional tube 63 is provided in the placement groove 62.

[0092] The integrated functional tube 63 is equipped with a reinforcing hose and a circulating curing hose. The reinforcing hose is connected to the jet pump, and the circulating curing hose is connected to the high-temperature reciprocating pump.

[0093] The reinforcement component 7 includes a second annular spray head 72 and a compression balloon 73. The second annular spray head 72 and the compression balloon 73 are connected by a fixed semi-hollow tube 74 embedded inside them, and the fixed semi-hollow tube 74 is connected to the integrated functional tube 63. The second annular spray head 72 is connected to the reinforcement hose, and one end of the second annular spray head 72 is connected to the damper. The compression balloon 73 is connected to the circulating curing hose. One end of the fixed semi-hollow tube 74 is provided with an insertion groove 75 and a T-shaped sealing groove 76. The insertion groove 75 and the T-shaped sealing groove 76 are connected. The T-shaped sealing groove 76 is connected to the compression balloon 73. A sealing slider 77 is slidably connected in the T-shaped sealing groove 76. A fixing rod is fixedly connected to the bottom end of the sealing slider 77.

[0094] Among them, the bonding and fixing component 6 is the core functional module of this device to achieve final hot-press bonding and curing. Its design aims to solve two major problems in the background technology: First, for the problem of "weak interface", this component transforms the traditional "surface bonding" into a firm "body embedding" through the synergistic effect of heat and pressure; Second, for the problem of "incomplete bonding", this component can ensure that the protective layer achieves a gapless and complete bonding to the inner wall of complex flow channels, including concave points.

[0095] This component integrates hot-press curing and secondary reinforcement functions, and features a cleverly designed automatic docking and locking mechanism, enabling the protective tube 44 to be processed from the inside out through the flow channel.

[0096] This module uses the bonding and fixing box 61 as a carrier, and adopts a compartmentalized design internally, integrating two independent fluid systems:

[0097] The reinforcement system consists of a reinforcement tank for storing the reinforcement agent and an injection pump that provides the power for delivery. It is responsible for subsequent reinforcement treatment.

[0098] Hot-press curing system: It consists of an extrusion chamber for storing curing liquid and a core high-temperature reciprocating pump. This system is the key to this process. The high-temperature reciprocating pump can not only provide high pressure, but also precisely control the temperature of the curing liquid, which is the basis for realizing the "hot pressing" function.

[0099] The functions of the above system are transmitted to the execution end—the reinforcement component 7—through the integrated functional tube 63. It integrates two functional heads: the second annular spray head 72 is used to spray the reinforcement agent onto the inner wall of the protective tube 44; the compression balloon 73 is the component that directly performs the hot pressing action. The two are connected by a fixed semi-hollow tube 74.

[0100] When the insertion rod 54 at the front end of the adsorption spray pipe 52 is inserted into the insertion slot 75 of the reinforcement 7, the high-temperature reciprocating pump starts immediately. Driven by the pump, the curing liquid flows through the circulating curing hose to two destinations simultaneously: one is the inner cavity of the compression balloon 73, and the other is the T-shaped sealing groove 76 connected to it.

[0101] As the curing liquid enters the compression bladder 73 and fills it with pressure, it also pushes the sealing slider 77 in the T-shaped sealing groove 76 to produce a horizontal displacement. The sealing slider 77 in the T-shaped sealing groove 76 is designed as a mechanical seal, thereby maintaining its sealing performance.

[0102] The fixing rod connected to the bottom of the sealing slider 77 is then precisely inserted into the fixing groove 55 on the insertion rod 54, instantly completing the rigid mechanical locking between the reinforcement 7 and the adsorption spray pipe 52.

[0103] After locking is completed, the rigid assembly formed by the adsorption spray pipe 52 and the reinforcement 7 can be inserted into the metal flow channel as a whole under the drive of the moving electric push rod 32. When it reaches the predetermined position in the flow channel, the high-temperature reciprocating pump further increases the output pressure, causing the pressure of the curing liquid already in the extrusion bladder 73 to increase dramatically, causing the extrusion bladder 73 to go from a full state to an expanded state, thereby applying uniform radial thermal pressure to the outer protective tube 44.

[0104] The inflated extrusion balloon 73 applies uniform radial pressure to the protective tube 44 fitted inside the flow channel. At the same time, its heat is transferred to the protective tube 44 through the balloon wall, causing it to soften and undergo plastic deformation. Under the combined action of heat and pressure, the protective tube 44 is tightly pressed into the extrusion indentation on the inner wall of the metal flow channel, and excess adhesive is squeezed out.

[0105] The heat also significantly accelerated the initial curing of the adhesive, achieving simultaneous "pressure molding" and "thermal curing".

[0106] After the compression balloon 73 is hot-pressed, the jet pump can be started to spray the reinforcing agent evenly onto the inner wall of the compacted and tightly attached protective tube 44 through the second annular spray head 72, forming an enhanced coating. This creates a composite liner structure of "metal-adhesive-protective tube-reinforcing agent" inside the flow channel, further improving corrosion resistance, pressure resistance, and long-term service performance. After completion, the processed flow channel panels are assembled to obtain the final metal cabinet. This assembly method is existing technology and will not be described in detail here.

[0107] Subsequently, the high-temperature reciprocating pump is used again to squeeze the solidified liquid in the balloon 73 back, so that the sealing slider 77 in the T-shaped sealing groove 76 is reset under pressure, thereby releasing the restriction with the adsorption spray pipe 52. This allows the second annular spray head 72 to be reset under the action of the damper and to abut against the placement frame. All components are reset, and the preparation for the first operation can begin.

[0108] It is important to note that the core function of the curing liquid is to act as a medium for transferring hot pressing energy. Therefore, it must have excellent thermal stability and thermal conductivity. Synthetic high-temperature heat transfer oils such as hydrogenated terphenyl, alkylbenzene, or silicone oils are preferred.

[0109] The material of the above-mentioned preferred curing liquid has good thermal oxidation stability, moderate viscosity, and is not prone to coking in the temperature range of 120℃ to 180℃ or even higher. It can ensure the long-term stable operation of the high-temperature reciprocating pump and efficiently and evenly transfer heat to the protective tube and adhesive through the extrusion bladder wall.

[0110] The reinforcing agent is used to form a reinforcing coating on the inner wall of the hot-pressed protective tube 44. Its selection needs to produce a strong chemical bond with the pre-cured epoxy adhesive. There are two main options: epoxy-based reinforcing coatings or high-resistance silane coupling agents.

[0111] The compression balloon is a key component that directly performs "hot compression" and must simultaneously meet the requirements of heat resistance, pressure resistance, high elasticity, high thermal conductivity, and chemical inertness. Fluororubber or perfluoroether rubber is preferred, as this material can maintain its elasticity for a long time at a high temperature of 180°C and has excellent durability.

[0112] To improve thermal conductivity, highly thermally conductive nano- or micron-sized ceramic powders, such as aluminum nitride or boron nitride, can be uniformly filled into the rubber matrix, which can significantly improve the efficiency of heat transfer from the internal curing liquid to the outside of the capsule wall.

[0113] Regarding the material of the protective tube 44, the preferred material is selected based on the final application of the metal cabinet flow channel: when used for water cooling, the preferred material is polypropylene (PP) or cross-linked polyethylene (PEX) reinforced with thermally conductive filler, to ensure good insulation and barrier properties while minimizing thermal resistance.

[0114] When used for chemical corrosion protection, the preferred material is perfluoroplastic or high-performance polyamide to provide a near-inert, complete chemical barrier.

[0115] The materials used for water cooling or chemical corrosion protection are all thermoplastic polymers. Their softening or melting temperatures are matched with the hot pressing process window of 120°C to 180°C, ensuring that they can undergo plastic deformation under the heat provided by the extrusion bladder 73, fully filling the flow channel recesses and achieving three-dimensional bonding. At the same time, their surface properties ensure good interfacial bonding with the epoxy resin adhesive and separability from the extrusion bladder.

[0116] It should be noted that, in order to protect the inner wall of the already lined flow channel, the final cabinet assembly does not use connection processes that generate high heat, such as welding.

[0117] Therefore, the final assembly of the processed flow channel panel with other cabinet structural components (such as side panels, top panels, bottom panels, etc.) preferably adopts a mechanical connection method.

[0118] For example, high-precision connection holes can be pre-punched on the edges of the panel and structural components, and assembly can be carried out by high-strength threaded connection (such as internal hexagon screws) or snap-fit ​​mechanical interlocking structure. This assembly method is a mature existing technology that can ensure assembly accuracy and structural strength, while completely avoiding the risk of thermal damage to the internal protective tube (44) and adhesive curing layer caused by high welding temperature, thus ensuring the long-term integrity of the protective liner.

[0119] In summary, the bonding and fixing component 6 is a precision end-effector system that integrates automatic docking, mechanical locking, intelligent hot pressing, and inner wall reinforcement.

[0120] By using a high-temperature fluid-driven flexible capsule as the force-applying medium, the problem of high-quality lining for complex irregular cavities is solved. This is the decisive module for achieving the final processing goal of high precision and high reliability of the entire device.

Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
