Description

Technical Field

[0001] This invention relates to the field of material surface treatment technology, specifically to a heat treatment device and method for computer parts. Background Technology

[0002] Computer parts are mostly precision, irregularly shaped metal structures, and the precision of their surface heat treatment directly affects their performance and service life.

[0003] Traditional computer component surface heat treatment equipment often uses rigid clamping methods such as jigs and chucks to fix the parts. Rigid clamping can easily cause surface scratches on precision computer components, and the clamping force can easily cause stress deformation of the parts, resulting in the parts exceeding the form and position tolerance after heat treatment and reducing the yield rate. For computer components with irregular contours, rigid jigs are difficult to achieve full fit and support, and the parts are prone to displacement during heat treatment, affecting the uniformity of heat treatment. In addition, traditional equipment lacks an effective waste heat recovery structure, and a large amount of waste heat generated during heat treatment is directly lost, resulting in energy waste. At the same time, waste heat radiation can easily affect the service life of the surrounding components of the equipment. The clamping and positioning process of some equipment is cumbersome and has a low degree of automation, resulting in low efficiency of heat treatment operation and difficulty in adapting to the needs of mass production. Summary of the Invention

[0006] Preferably, a robotic arm is provided on one side of the machine body, and a gripper is provided on the top of the robotic arm.

[0007] Preferably, two top inspection doors are hinged to the upper front end of the machine body, and a flexible heat insulation curtain is provided at the bottom of the top inspection door. The flexible heat insulation curtain corresponds to the top of the support platform. Two bottom inspection doors are hinged to the bottom end of the machine body at the front end of the machine body, and self-locking casters are provided at the four corners of the bottom end of the machine body.

[0008] Preferably, the interior of both waste heat recovery chambers is filled with metal or ceramic-based material, and the exterior of both waste heat recovery chambers is detachably covered.

[0009] Preferably, a vacuum line quick connector is provided at the top rear end of the support platform, a fluid injection and release valve is provided on the top of the support platform on one side of the vacuum line quick connector, a multi-way electrical quick-connect interface is provided on the top of the support platform on the side of the fluid injection and release valve, a flexible printed circuit is provided on one side of the shape memory alloy drive array, a fluid input and output port are provided inside one side of the pouch structure, a vacuum interface is provided inside the pouch structure on the side of the fluid input and output port, the vacuum line quick connector is connected to the vacuum interface, the fluid input and output port is connected to the fluid injection and release valve, and the flexible printed circuit is connected to the multi-way electrical quick-connect interface.

[0010] Preferably, a vacuum pump is connected to the bottom of the vacuum pipeline quick connector, a miniature metering gear pump is connected to the bottom of the fluid filling and venting valve, and a pulse current drive module is connected to the bottom of the multi-way electrical quick connector. The vacuum pump, the miniature metering gear pump, and the pulse current drive module are all connected inside the support platform.

[0011] Preferably, the top of the pouch structure is provided with a Velcro surface, and a protective layer is detachably installed on the top of the pouch structure through the Velcro surface.

[0012] Preferably, the shape memory alloy driven array is pre-woven into a two-dimensional planar mesh by multiple superelastic nickel-titanium alloy wires.

[0013] Preferably, the bladder structure is formed by heat sealing a single-layer flexible graphene-reinforced composite film to create a completely sealed bladder. The upper wall of the bladder is thinner to facilitate deformation, while the lower wall is thicker to bear weight.

[0014] A heat treatment apparatus and method for surface treatment of computer parts, comprising the following steps: S1: Equipment preparation and parts placement. The operator opens the top and bottom access doors and places the computer parts to be processed on the protective layer at the top of the bag structure using the robotic arm and its gripper or manually. S2: Part contour scanning and adaptive wrapping. The 3D vision system integrated into the device quickly scans the bottom surface of the part to obtain its three-dimensional contour data. Based on the contour data, the system outputs pulse current to the corresponding specific unit in the shape memory alloy drive array through multiple electrical quick-connect interfaces and flexible printed circuits. The heated SMA unit contracts, pulling the local concavity of the bag structure. Under the fluid-structure coupling effect of the modified silicone oil inside, the upper wall of the bag tightly and stress-free wraps and adheres to the lower surface and sides of the part, forming a contour support. S3: Vacuum rigidification locking. After the bag structure completes self-adaptive wrapping, the vacuum pump in the support platform is started. The vacuum pipeline draws a vacuum into the inner cavity of the bag through the vacuum pipeline quick connector and vacuum interface. Under the action of negative pressure, the bag, modified silicone oil, SMA array and parts are pressed into a rigid whole, realizing the firm locking and fixing of the parts. S4: Part positioning and heat treatment. The control system activates the lead screw assembly, driving the support platform to move along the slide rail, sending the locked part's pouch structure into the heat treatment station defined by the top and bottom U-shaped buckles. The top and bottom inspection doors are closed, and a flexible heat insulation curtain is lowered to isolate the heat zone. The heat treatment source, such as laser or plasma, is activated. Essential functional components of this type of device, not specifically illustrated in the document, perform surface heat treatment on the part. During the process, the metal or ceramic-based material filling the waste heat recovery chambers on both sides of the machine body absorbs some of the waste heat. S5: Reset and part removal. After the heat treatment process is completed, the heat treatment source is turned off. After the part is properly cooled, the vacuum of the bag structure is released, and its interior is restored to normal pressure. The shape memory alloy drive array stops heating and cools down to restore its original shape. The bag restores its flat shape under its own elasticity and the action of the medium. The part is released, and the lead screw assembly drives the support platform to return to the initial position. S6: Maintenance and preparation. The processed parts are removed by the gripper. The operator can periodically remove and replace the protective layer through the Velcro for maintenance. If necessary, the modified silicone oil inside the bag structure can be replaced or replenished through the fluid filling and draining valve and the miniature metering gear pump.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This computer component surface heat treatment device and method, through the combination of a bag structure, shape memory alloy driving array and modified silicone oil, achieves stress-free contour wrapping support for computer components. Combined with vacuum rigid locking, it replaces the traditional rigid clamping method, which not only avoids stress deformation and surface scratches caused by clamping force, but also achieves full fit and fixation of irregular contour parts, ensuring no displacement of parts during heat treatment, and greatly improving heat treatment accuracy and part yield.

[0016] 2. This computer parts surface heat treatment device and its usage method, through the waste heat recovery chamber filled with metal or ceramic-based heat storage materials, can effectively absorb and store the waste heat generated during the heat treatment process, realize energy recovery and reuse, reduce energy consumption, and at the same time reduce the impact of waste heat radiation on the surrounding components of the device, extending the overall service life of the device. It integrates a robotic arm and gripper to realize automated loading and unloading of parts. With the precise switching of the screw assembly and slide rail, it improves the automation level and efficiency of the heat treatment operation, and is suitable for batch production needs.

[0017] 3.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 5 As shown, the computer component surface heat treatment device of this embodiment includes a body 1, which serves as the support and protective carrier for the entire device, integrating all functional components to provide a closed and stable working space for heat treatment operations. The body 1 typically contains heat treatment sources such as lasers or plasmas. A support platform 14 is provided inside the body 1 to support the bag structure and various power, control, and fluid components. It is the core support component for component placement and heat treatment positioning. A bag structure 13 is provided at the top of the support platform 14, serving as the core structure for adaptive fitting support of the components, achieving stress-free wrapping of computer components with different contours. The internal cavity of the bag structure 13 is filled with modified silicone oil, utilizing the flow properties of the modified silicone oil... The solid coupling characteristics, combined with the deformation of the bag, achieve a tight fit with the contour of the part, while also possessing good thermal conductivity and shaping effect. The bottom inner wall of the bag structure 13 is provided with a shape memory alloy drive array 25, which serves as the power source for the bag structure's conformal deformation. It achieves local contraction through electric drive, causing the bag to adapt to the contour of the part. The bottom two edges of the support platform 14 are connected to the inside of the machine body 1 by slide rails 12, which provide guidance and limit for the horizontal movement of the support platform, ensuring the smoothness and positioning accuracy of the support platform's movement. A lead screw assembly 10 is provided at the middle position of the bottom of the support platform 14, which serves as the horizontal drive component of the support platform. Through lead screw transmission, the support platform moves along the slide rail, realizing the switching of the part between the loading / unloading position and the heat treatment position. The front end of the inside of the machine body 1 is provided with two bottom U-shaped buckles 11, which cooperate with the top U-shaped buckles to define the range of the heat treatment position, achieving precise positioning of the support platform and ensuring the positional accuracy of the heat treatment operation. The rear end edge of the bottom of the support platform 14 is provided with two top U-shaped buckles 18, which cooperate with the bottom U-shaped buckles. The buckle fits together to form a station positioning buckle, which precisely limits the position of the support table in the heat treatment station and prevents the support table from shifting during the heat treatment process. Both sides of the body 1 above the support table 14 are provided with waste heat recovery chambers 4, which are used to absorb and store the waste heat generated during the heat treatment process, realize the recovery and utilization of waste heat, reduce energy consumption, and reduce heat radiation inside the device.

[0023] Specifically, a robotic arm 8 is provided on one side of the machine body 1 as an automated loading and unloading execution component, which realizes the automatic gripping and placement of parts to be processed and processed parts, thereby improving the automation level of the device. The top of the robotic arm 8 is provided with a gripper 9, which serves as the execution end of the robotic arm, adapting to the gripping of computer parts of different specifications, ensuring the stability of part gripping, and avoiding damage to the surface of the parts during gripping.

[0024] Furthermore, two top inspection doors 2 are hinged to the upper front of the machine body 1, facilitating the operator's inspection and maintenance of components such as the heat treatment source and waste heat recovery chamber on the upper part of the device. These doors can also be opened for manual loading and unloading of parts. A flexible heat insulation curtain 7 is installed at the bottom of the top inspection door 2, providing excellent heat insulation performance. During heat treatment, it hangs down to isolate the heat treatment zone from the external space, reducing heat loss and preventing heat radiation from harming the operator. The flexible heat insulation curtain 7 corresponds to the top of the support platform 14, ensuring that the insulation range covers the heat treatment station and guarantees the heat insulation effect. Two bottom inspection doors 6 are hinged to the front of the machine body 1 at the bottom of the flexible heat insulation curtain 7, facilitating the inspection, debugging, and maintenance of core components such as the support platform, screw assembly, and vacuum pump on the lower part of the device. Self-locking casters 5 are installed at the four corners of the bottom of the machine body 1, enabling the overall movement of the device and facilitating installation, debugging, and station adjustment. The self-locking function ensures the stability of the device during operation.

[0025] Furthermore, the interiors of both waste heat recovery chambers 4 are filled with metal or ceramic-based materials. Utilizing the high specific heat capacity and good thermal conductivity of the metal or ceramic-based materials, the waste heat generated during heat treatment is efficiently absorbed and stored, thereby realizing waste heat recovery. The outer sides of both waste heat recovery chambers 4 are detachably equipped with protective covers 3, which facilitates the replacement and maintenance of the heat storage materials inside the waste heat recovery chambers, while also providing protection for the waste heat recovery chambers.

[0026] Furthermore, a vacuum pipeline quick connector 16 is provided at the top rear end of the support platform 14, serving as a quick connection component for the vacuum pipeline. This facilitates the convenient connection and disconnection of the vacuum pump and the vacuum interface of the bag structure, simplifying device maintenance and component replacement. A fluid filling and drain valve 20 is provided on the top of the support platform 14 on one side of the vacuum pipeline quick connector 16. This valve controls the filling, draining, and on / off of modified silicone oil inside the bag structure, enabling the replenishment, replacement, and sealing control of the modified silicone oil. A multi-way electrical quick-connect interface 21 is provided on the top of the support platform 14 on one side of the fluid filling and drain valve 20. This serves as a quick interface for electrical connections, enabling multiple electrical connections between the pulse current drive module and the shape memory alloy drive array, facilitating wiring and component maintenance. A flexible printed circuit 26 is provided on one side of the shape memory alloy drive array 25, providing precise pulse current transmission to each unit of the shape memory alloy drive array. The deformation of the capsule ensures the stability of circuit transmission. One side of the capsule structure 13 has a fluid inlet and outlet 27, which serves as a channel for the modified silicone oil to enter and exit the capsule structure, realizing the filling and discharge of the modified silicone oil. The capsule structure 13 on the side of the fluid inlet and outlet 27 has a vacuum interface 22, which serves as a vacuum channel for the capsule structure, realizing the negative pressure extraction of the capsule cavity by the vacuum pump. The vacuum pipeline quick connector 16 is connected to the vacuum interface 22 to form a complete vacuum pipeline, ensuring that the negative pressure of the vacuum pump can be effectively transmitted to the capsule cavity. The fluid inlet and outlet 27 is connected to the fluid filling and venting valve 20 to form a complete fluid pipeline, realizing precise control of the modified silicone oil inside the capsule. The flexible printed circuit 26 is connected to the multi-channel electrical quick connector 21 to form a complete electrical control circuit, realizing the independent control of each unit of the shape memory alloy drive array by the pulse current drive module.

[0027] Furthermore, a vacuum pump 15 is connected to the bottom of the vacuum pipeline quick connector 16, serving as the power source for evacuating the bag structure and providing a stable negative pressure to the inner cavity of the bag, thus achieving rigid locking of the bag. A micro metering gear pump 17 is connected to the bottom of the fluid filling and discharge valve 20, serving as the power source for transporting modified silicone oil, achieving precise metering and filling of modified silicone oil, and ensuring accurate filling of modified silicone oil inside the bag. A pulse current drive module 19 is connected to the bottom of the multi-channel electrical quick connector 21, serving as the electrical control and power source for the shape memory alloy drive array, which can output pulse currents with different parameters to independently control the contraction of each unit of the drive array. The vacuum pump 15, the micro metering gear pump 17, and the pulse current drive module 19 are all connected inside the support platform 14, realizing the integrated installation of the core power and control components, saving device space, and ensuring close connection between the components and the working end, thereby improving transmission efficiency.

[0028] Furthermore, the top of the pouch structure 13 is provided with a Velcro surface 23, which serves as a detachable connecting component for the protective layer, enabling quick installation and removal of the protective layer and facilitating its replacement and cleaning. The top of the pouch structure 13 is detachably fitted with a protective layer 24 via the Velcro surface 23, providing double protection for the pouch structure and computer components. This prevents direct contact between the components and the pouch, thus avoiding wear and tear, while also preventing direct damage to the pouch from the high temperatures of heat treatment.

[0029] Furthermore, the shape memory alloy driving array 25 is pre-woven into a two-dimensional planar grid by multiple ultra-elastic nickel-titanium alloy wires. The grid structure ensures the uniformity and controllability of the deformation of the driving array. The shape memory characteristics of the ultra-elastic nickel-titanium alloy wires enable precise contraction under electric drive, leading to local deformation of the bladder. (The original document was missing the word "multiple", which has been added here.)

[0030] Furthermore, the capsule structure 13 is formed by thermally sealing a single-layer flexible graphene-reinforced composite film to create a completely sealed capsule. Utilizing the flexibility, high temperature resistance, and high strength of the graphene-reinforced composite film, the capsule's deformability and structural strength are guaranteed. The completely sealed structure prevents leakage of modified silicone oil and air leakage during vacuuming. The upper wall of the capsule is relatively thin to facilitate deformation, ensuring that the upper wall of the capsule can flexibly achieve local concavity as the shape memory alloy driven array contracts, adapting to the complex contours of the parts. The lower wall is relatively thick to bear the weight, ensuring that the lower wall of the capsule can stably support the weight of the parts and modified silicone oil, while also withstanding the negative pressure after vacuuming, preventing deformation and damage to the lower wall of the capsule.

[0031] A heat treatment apparatus and method for surface treatment of computer parts, comprising the following steps: S1: Equipment preparation and parts placement. The operator opens the top inspection door 2 and the bottom inspection door 6 to open the working channel of the device. At the same time, the operator prepares to power on and supply the medium to the internal components of the device, ensuring that the equipment is in a ready-to-work state. The computer parts to be processed are placed on the protective layer 24 on the top of the bag structure 13 by the robotic arm 8 and its gripper 9 or manually, thus achieving the initial placement of the parts. The protective layer prevents the parts from directly contacting the bag and prevents scratches on the surface of the parts. S2: Part contour scanning and adaptive wrapping. A 3D vision system integrated into the device rapidly scans the bottom surface of the part to quickly acquire accurate 3D contour data. The control system analyzes and processes this data, matching it to the corresponding unit of the shape memory alloy (SMA) drive array. Precise electrical drive commands are generated and output to the corresponding specific unit in the shape memory alloy drive array 25 via the multi-channel quick-connect interface 21 and flexible printed circuit 26. This achieves precise electrical drive of the specific unit in the drive array, ensuring that the deformation of the bag structure 13 matches the part contour. The heated SMA unit contracts, pulling the local concavity of the bag structure 13, utilizing the SMA... The contraction force of the unit causes the bag to deform in a targeted manner, forming a support surface that matches the contour of the part. Under the fluid-structure coupling effect of the modified silicone oil inside, the upper wall of the bag structure 13 tightly and stress-free wraps and adheres to the lower surface and sides of the part, forming a contour support. The modified silicone oil deforms with the bag structure 13 to fill the gap between the part and the bag structure 13, achieving stress-free wrapping, avoiding stress deformation during part clamping, and improving the accuracy of heat treatment.

[0032] S3: Vacuum rigidification locking. After the bag structure 13 completes its self-adaptive wrapping, the vacuum pump 15 inside the support platform 14 is activated to provide negative pressure power for evacuating the bag structure 13. The vacuum pipeline draws a vacuum from the inner cavity of the bag structure 13 through the vacuum pipeline quick connector 16 and the vacuum interface 22, forming a complete negative pressure transmission path. This draws out the air from the inner cavity of the bag structure 13, creating a stable negative pressure. Under the action of negative pressure, the bag structure 13, modified silicone oil, SMA array, and parts are pressed together into a rigid whole, achieving a firm locking and fixing of the parts. The compression effect of negative pressure transforms the flexible bag structure 13 into a rigid support, ensuring that the parts do not shift during heat treatment and improving the positioning accuracy of heat treatment.

[0033] S4: Part positioning and heat treatment. The control system starts the screw assembly 10, driving the support platform 14 to move along the slide rail 12. The screw drive achieves precise horizontal movement of the support platform, ensuring accurate switching of workstations. The locked part bag structure 13 is sent into the heat treatment station defined by the top U-shaped buckle 18 and the bottom U-shaped buckle 11, achieving precise positioning of the part for heat treatment and ensuring accurate application of the heat treatment source. The top inspection door 2 and the bottom inspection door 6 are closed to form a closed heat treatment work space, reducing heat loss and improving heat treatment efficiency. The flexible heat insulation curtain 7 is lowered to isolate the heat zone, further isolating the heat treatment heat zone from the outside of the device, preventing heat radiation leakage, and ensuring operational safety. The heat treatment source, such as laser or plasma, is activated. The necessary functional components of this type of device, which are not specifically illustrated in the document, perform surface heat treatment on the part. The heat treatment source modifies the surface of the part, improving the hardness, wear resistance, and other properties of the computer part surface. During the process, the metal or ceramic matrix material filled in the waste heat recovery chambers 4 on both sides of the main body 1 can absorb part of the waste heat, realize the recovery and utilization of waste heat from heat treatment, reduce energy consumption, and at the same time reduce the internal temperature of the device, reducing the impact of heat on other components.

[0034] S5: Reset and Part Removal. After the heat treatment process is completed, the heat treatment source is turned off, and the heat treatment operation on the part is stopped to prevent excessive heat treatment from damaging the performance of the part. After the part has cooled down appropriately, avoid deformation or burns to the operator when handling the part at high temperature. At the same time, prevent high temperature from damaging the bag structure. Release the vacuum of the bag structure 13 to restore its internal normal pressure, release the pressure of the negative pressure, and restore the rigid whole to flexibility, making it easy to remove the part. The shape memory alloy drive array 25 stops heating and cools down to restore its original shape. The SMA unit returns to its initial shape to prepare for the next contour deformation. The bag returns to its flat shape under its own elasticity and the action of the medium. The bag returns to its initial state and releases the wrapping support on the part. The part is released, and the lead screw assembly 10 drives the support platform 14 to return to the initial position to realize the reset of the support platform, which is ready for the removal of the part and the next operation.

[0035] S6: Maintenance and Preparation. The processed parts are removed using the gripper 9, achieving automated removal and improving operational efficiency. Operators can periodically remove and replace the protective layer 24 via the Velcro surface 23 for maintenance, promptly replacing worn protective layers to ensure protective effectiveness and extend the lifespan of the bag structure. If necessary, the modified silicone oil inside the bag structure 13 can be replaced or replenished via the fluid filling and releasing valve 20 and the micro-metering gear pump 17 to ensure the filling quantity and performance of the modified silicone oil inside the bag, ensuring the contour wrapping effect. The usage method of this embodiment is as follows: First, confirm that the wiring and pipeline connections of each component of the device are intact, the self-locking casters 5 are locked, and the cover 3 of the waste heat recovery chamber 4 is installed in place. Then, the operator turns on the main power of the machine body 1 to start the control system and completes the self-test and initialization of the 3D vision system, robotic arm 8, vacuum pump 15, micro metering gear pump 17, and pulse current drive module 19. After the system displays that each component is normal, open the top inspection door 2 and the bottom inspection door 6 to check whether the protective layer 24 on the top of the bag structure 13 is intact and whether the modified silicone oil level inside the bag is within the preset range. If there is wear or insufficient, replace and replenish it in time. Then, select automatic or manual feeding of the robotic arm according to the specifications of the parts to be processed, place the parts stably in the center of the protective layer 24, and confirm that there is no hard contact between the parts and the bag. With the foreign object sandwiched in the middle, the control system then activates the 3D vision system to quickly perform a three-dimensional scan of the bottom surface and lower side of the part, generating a part contour model and matching it with the corresponding unit of the shape memory alloy drive array 25. Through the multi-channel electrical quick-connect interface 21 and the flexible printed circuit 26, a pulse current with preset current parameters is output to the specific unit. The heat-shrinkable nickel-titanium alloy wire pulls the corresponding position of the bag structure 13 to locally concave inward. Under the fluid-solid coupling effect of the modified silicone oil, the upper wall of the bag and the protective layer 24 tightly and stress-free wrap and adhere to the lower surface and side of the part to form a contour support. The system detects the fit in real time to ensure that there is no suspension or compression. After the contour wrapping fit reaches the preset value, the control system automatically starts the vacuum pump 15 to slowly evacuate the inner cavity of the bag. When the negative pressure reaches -0.08~-0.At 0.9 MPa, the vacuum pump switches to pressure-holding mode, pressing the bag, modified silicone oil, shape memory alloy drive array 25, and part into a rigid whole for secure locking. Then, the control system activates the lead screw assembly 10 to drive the support platform 14 smoothly forward along the slide rail 12. Once the top U-shaped buckle 18 and bottom U-shaped buckle 11 engage and the positioning sensor is triggered, the lead screw assembly stops working, and the part is precisely fed into the heat treatment station. The operator closes the top inspection door 2 and bottom inspection door 6, allowing the flexible heat insulation curtain 7 to descend and isolate the heat zone. The control system sets the laser power, heat treatment time, and other heat treatment process parameters and confirms entry into the ready-to-start state. After confirming all preparations are complete, the heat treatment process begins. The heat source performs surface heat treatment according to preset parameters. During the process, the metal / ceramic-based heat storage material in the waste heat recovery chamber 4 absorbs waste heat for recycling, while simultaneously reducing the internal ambient temperature to protect precision components. After the heat treatment process is completed, the control system automatically shuts off the heat treatment source. Natural cooling is then used. Once the system detects that the surface temperature of the part has dropped to a preset safety value of ≤80℃, the vacuum pump 15 slowly depressurizes to restore the inner cavity of the bag to normal pressure. The pulse current drive module 19 stops supplying power, and the shape memory alloy drive array 25 naturally cools and recovers. The bag structure 13 returns to flatness under its own elasticity and the action of modified silicone oil fluid, releasing the part. Then, the control system starts the lead screw assembly 10 to rotate in the reverse direction. The drive support platform 14 retracts to the initial loading and unloading position. After the operator opens the maintenance door, the processed parts are removed and transferred to the unloading area by means of a robotic arm or manually, completing a single heat treatment operation. After a single operation, the device is subjected to simple maintenance, including regular inspection and replacement of worn protective layer 24 through Velcro 23. The modified silicone oil that is turbid or insufficient is quantitatively discharged or replenished through fluid injection and discharge valve 20 and micro metering gear pump 17. At the same time, the sealing of each pipeline and the stability of the interface connection are checked, and impurities on the surface of the bag and the protective layer are cleaned. After confirming that all components are reset, the heat treatment process for the next batch of parts can begin. After all operations for the day are completed, the operator shuts down the controls in sequence. After the internal temperature of each functional component has dropped to room temperature, turn off the main power supply and clean up any debris in the work area. If the machine will not be used for a long period, fill the inner cavity of the bag with a small amount of dry nitrogen to prevent aging of the bag, and close the maintenance door to protect the equipment from dust. Throughout the operation, pay attention to the slow vacuuming and depressurization process to avoid sudden changes in negative pressure that could cause deformation of parts or damage to the bag. During heat treatment, it is strictly forbidden to open the maintenance door or touch the flexible heat insulation curtain 7. When replacing the protective layer or adding modified silicone oil, disconnect the power supply first. Adapt the current parameters of the shape memory alloy drive array 25 according to the contour of the part and strictly prohibit exceeding the parameter output.

10. A heat treatment apparatus and method for surface treatment of computer parts, characterized in that: Includes the following steps: S1: Equipment preparation and parts placement. The operator opens the top access door (2) and the bottom access door (6) and places the computer parts to be processed on the protective layer (24) on top of the bag structure (13) by means of the robotic arm (8) and its gripper (9) or manually. S2: Part contour scanning and adaptive wrapping. The bottom surface of the part is quickly scanned by the 3D vision system integrated in the device to obtain its three-dimensional contour data. According to the contour data, the system outputs pulse current to the corresponding specific unit in the shape memory alloy drive array (25) through the multi-channel electrical quick-connect interface (21) and flexible printed circuit (26). The heated SMA unit contracts and pulls the local concavity of the bag structure (13). Under the fluid-solid coupling effect of the internal modified silicone oil, the upper wall of the bag tightly and stress-free wraps and adheres to the lower surface and side of the part, forming a contour support. S3: Vacuum rigidification locking. After the bag structure (13) completes adaptive wrapping, the vacuum pump (15) in the support platform (14) is started. The vacuum pipeline draws a vacuum from the inner cavity of the bag through the vacuum pipeline quick connector (16) and the vacuum interface (22). Under the action of negative pressure, the bag, modified silicone oil, SMA array and parts are pressed into a rigid whole, realizing the firm locking and fixing of the parts. S4: Part positioning and heat treatment. The control system starts the screw assembly (10), drives the support platform (14) to move along the slide rail (12), and sends the locked part's bag structure (13) into the heat treatment station defined by the top U-shaped buckle (18) and the bottom U-shaped buckle (11). The top inspection door (2) and the bottom inspection door (6) are closed, the flexible heat insulation curtain (7) is lowered to isolate the heat zone, and the heat treatment source is started to perform surface heat treatment on the part. During the treatment, the metal or ceramic matrix material filled in the waste heat recovery chambers (4) on both sides of the machine body (1) can absorb part of the waste heat; S5: Reset and part removal. After the heat treatment process is completed, the heat treatment source is turned off. After the part is properly cooled, the vacuum of the bag structure (13) is released, so that the inside is restored to normal pressure. The shape memory alloy drive array (25) stops heating and cools down. The bag restores its flat shape under its own elasticity and the action of the medium. The part is released, and the screw assembly (10) drives the support platform (14) to return to the initial position. S6: Maintenance and preparation, the processed parts are removed by the pick-up gripper (9). The operator can periodically remove and replace the protective layer (24) through the Velcro (23) for maintenance. If necessary, the modified silicone oil inside the bladder structure (13) can be replaced or replenished through the fluid filling and drain valve (20) and the micro metering gear pump (17).
