Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber sensitive ring assembly assembly process, and particularly relates to a stress releasing and curing device for optical fiber sensitive ring assembly. BACKGROUND

[0002] The optical fiber sensitive ring assembly is a core component in the optical fiber sensor, and is mainly used for sensing external changes such as vibration and temperature and measuring through optical signals. The optical fiber sensitive ring assembly is composed of an optical fiber ring, a Y waveguide optical integrator and a magnetic shielding shell. The optical fiber ring wound by a special device is placed in the magnetic shielding shell after being coated with glue, and is bonded by a curing process, and then the optical device is assembled. The optical fiber ring is one of the main elements restricting the application of the optical fiber sensitive ring assembly. The temperature performance and anti-interference ability of the optical fiber ring directly affect the performance of the optical fiber sensitive ring assembly. Improving the temperature stability and anti-vibration performance of the optical fiber ring is an important measure to improve the overall precision of the optical fiber sensitive ring assembly. In order to meet the vibration performance requirements of the optical fiber sensitive ring assembly, the wound optical fiber ring needs to be glued and cured in the magnetic shielding shell. Therefore, the bonding and curing quality of the optical fiber ring and the magnetic shielding shell will not only affect the stress distribution of the internal structure of the optical fiber ring, but also affect the temperature change performance of the optical fiber sensitive ring assembly, and even cause the optical fiber ring to crack, resulting in the scrap of the optical fiber sensitive ring assembly.

The feeding mechanism drives the telescopic disc to enter the shielding cover. The telescopic disc rotates to drive the ultraviolet light sources to rotate around the fiber disc to cure the optical fiber on the optical fiber ring skeleton. The structure is compact, occupies small space, has good curing effect, high curing efficiency and safe and reliable operation.

[0023] This invention provides an improved device for stress relief and curing of an optical fiber sensitive ring assembly, such as... Figures 1 to 15 As shown, it includes a processing box 1 and a vacuum device 102, which is used to perform vacuuming treatment on the inside of the processing box 1. The rotating mechanism 2, located inside the processing box 1, includes a drying rack 208 that rotates in opposite directions and a mounting plate 209. The mounting plate 209 has multiple through mounting cavities 2091 spaced apart. A positioning component 210 is provided in each mounting cavity 2091. The positioning component 210 is used to limit the magnetic shielding shell. The drying rack 208 includes multiple cantilever arms 2081. An ultraviolet lamp 2082 is provided on the side of the cantilever arm 2081 facing the mounting plate 209. The ultraviolet lamp 2082 is used to cure the magnetic shielding shell and the optical fiber ring.

[0024] This equipment is a dedicated stress relief and curing integrated device for fiber optic sensitive ring components. Through a synergistic mechanism of vacuum degassing, synchronous reverse rotation, and ultraviolet curing, it solves the problems of residual bubbles, uneven curing, and stress concentration during the bonding process between the fiber optic ring and the magnetic shielding shell.

[0025] Vacuum equipment 102 is an independent modular component, connected to the interior of processing chamber 1 via vacuum piping. The piping connects a vacuum valve, a high-precision vacuum gauge, and a filter. A rotary vane or dry vacuum pump with a pumping rate ≥2L / s is used, which can stably control the vacuum level within the chamber at 10-50mbar, enabling vacuum degassing of the adhesive and stress release assistance. Temperature and pressure sensors are built into the inner wall of the chamber to monitor environmental parameters in real time.

[0026] The rotating mechanism 2 is installed inside the processing chamber 1. Its core function is to achieve reverse rotation of the drying rack 208 and the mounting plate 209, ensuring uniform circumferential curing of the optical fiber ring. Activating the rotating mechanism 2 causes the drying rack 208 and the mounting plate 209 to rotate synchronously in opposite directions at 5-30 rpm. Simultaneously, the ultraviolet lamp 2082 is turned on, irradiating the fiber ring according to the preset power and curing time. This reverse rotation ensures uniform ultraviolet light reception around the circumference of the optical fiber ring, avoiding stress concentration caused by excessively rapid local curing and protecting the structural integrity of the optical fiber ring.

[0027] See appendix Figure 3-Appendix Figure 5 The rotating mechanism 2 also includes a first sliding seat 201 and a second sliding seat 202; a through first sliding groove 103 is provided on the top of the processing box 1; the first sliding seat 201 is slidably disposed in the first sliding groove 103, and the second sliding seat 202 is slidably disposed on the bottom inner wall of the processing box 1; the rotating mechanism 2 slides relative to the processing box 1 as a whole through the first sliding seat 201 and the second sliding seat 202.

[0028] In this embodiment: the rotating mechanism 2 achieves overall translation relative to the processing box 1, further improving operational convenience. The first sliding seat 201 is made of high-strength aluminum alloy, and the main body of the first sliding seat 201 is embedded in the first sliding groove 103 on the top of the processing box 1, with the sliding fit clearance controlled at 0.1-0.3mm. The top of the first sliding seat 201 extends outside the processing box 1, and the bottom is located inside the processing box 1, ensuring the vacuum sealing of the processing box 1 during the sliding process.

[0029] In this embodiment: the second sliding seat 202 is a flat sliding structure, which is slidably installed on the bottom inner wall of the processing box 1. The first sliding seat 201 and the second sliding seat 202 are fixedly connected by a rigid connecting rod to ensure that the two slide synchronously, avoid the rotating mechanism 2 from tilting or deviating during the sliding process, and ensure the coaxiality of the drying rack 208 and the mounting plate 209.

[0030] In this embodiment: the sealed door of the processing box 1 is opened, and the rotating mechanism 2 is slid along the first slide groove 103 and the second slide groove 104 to the door panel 3 of the processing box 1 by the control system or manual drive, leaving sufficient space for loading workpieces for loading equipment or maintenance and replacement.

[0031] See appendix Figure 4 -Appendix Figure 5 and attached Figure 9 A motor 203 is mounted on the first sliding seat 201. The motor 203 includes an output shaft 2031. The end of the output shaft 2031 is rotatably connected to the second sliding seat 202. The drying rack 208 is mounted on the output shaft 2031. The ultraviolet lamp tube 2082 includes an upper drying part 2083 located above the mounting plate 209 and a lower drying part 2084 located below the mounting plate 209.

[0032] In this embodiment: A servo motor 203 is selected as the motor 203, which is rigidly mounted on the top of the first sliding seat 201, i.e., outside the processing box 1, via a flange. The motor 203 housing is designed with an IP65 protection rating and has heat dissipation fins on its surface to ensure thermal stability during long-term operation. The output shaft 2031 of the motor 203 passes through the central through hole of the first sliding seat 201 and extends downward into the interior of the processing box 1. The mating point between the output shaft 2031 and the first sliding seat 201 adopts a magnetohydrodynamic seal structure. The magnetohydrodynamic seal ensures sealing performance during high-speed rotation of the output shaft and reduces transmission friction and wear.

[0033] In this embodiment: the output shaft 2031 is made of 40Cr alloy steel with a diameter of 15-20mm. The middle section of the output shaft 2031 is connected to the central drive shaft of the drying rack 208 by a key to realize the synchronous rotation of the drying rack 208.

[0034] In this embodiment, the cantilever 2081 of the drying rack 208 adopts an upper and lower structure design. Each cantilever 2081 is divided into upper and lower mounting surfaces along its length, respectively fixing the upper drying part 2083 and the lower drying part 2084, i.e., the upper and lower segments of the ultraviolet lamp tube 2082. The number of cantilever 2081 is 4-6, evenly distributed around the output shaft 2031 to ensure that the upper and lower areas of the mounting plate 209 are fully covered by ultraviolet light.

[0035] In this embodiment, each UV lamp tube 2082 is provided with an arc-shaped focusing cover on its outer side. The focal length of the focusing cover is adapted to the distance between the UV lamp tube 2082 and the workpiece, so that the UV light can be concentrated on the bonding area between the fiber optic ring and the magnetic shielding shell, thereby improving the light energy utilization rate and shortening the curing time.

[0036] See appendix Figure 5 -Appendix Figure 8 The second sliding seat 202 is rotatably mounted with a lower conical disk 204, which is located on the output shaft 2031. The rotating mechanism 2 also includes a protective cover 205 fixedly mounted on the second sliding seat 202, and an upper conical disk 206 is rotatably mounted on the top inner wall of the protective cover 205. The lower conical disk 204 includes a lower conical tooth 2041, and the upper conical disk 206 includes an upper conical tooth 2061. The rotating mechanism 2 also includes multiple linkage teeth 207, which mesh with the lower conical teeth 2041 and the upper conical teeth 2061 on both sides. A linkage cylinder 2063 is provided on the side of the upper conical disk 206 away from the direction of gravity, the output shaft 2031 passes through the linkage cylinder 2063, and the mounting plate 209 is mounted on the linkage cylinder 2063.

[0037] In this embodiment: the lower conical disk 204 adopts a bevel gear structure, made of 20CrMnTi alloy steel, with a cone angle of 45° and an involute tooth profile. A shaft hole is formed at the center of the lower conical disk 204, which is fixedly connected to the output shaft 2031 via a flat key, rotating synchronously with the output shaft 2031. The upper conical disk 206 has a symmetrical structure and identical parameters to the lower conical disk 204, and is also made of 20CrMnTi alloy steel. The axis of the upper conical disk 206 coincides with the axis of the lower conical disk 204 to ensure meshing accuracy.

[0038] In this embodiment: the linkage gear 207 is a cylindrical bevel gear, i.e., an intermediate gear, made of 20CrMnTi alloy steel. Its module and tooth profile are perfectly matched with the lower bevel gear 2041 and the upper bevel gear 2061, with 12-18 teeth. There are 2-3 linkage gears 207, evenly distributed along the circumference of the lower conical disk 204 and the upper conical disk 206. Each linkage gear 207 is rotatably connected to the second sliding seat 202 via a rotating shaft, ensuring that the rotational speeds of the upper conical disk 206 and the lower conical disk 204 are equal in magnitude and opposite in direction.

[0039] In this embodiment: the protective cover 205 is a cylindrical sealed housing, which is fixedly installed on the upper surface of the second sliding seat 202 by bolts. The inside of the cover forms a sealed chamber, completely enclosing the lower conical plate 204, the upper conical plate 206, and the linkage gear 207. A sealing gasket is provided at the connection between the bottom of the protective cover 205 and the second sliding seat 202 to ensure the vacuum seal in the chamber, prevent adhesive volatiles or impurities from contaminating the bevel gear transmission mechanism, and reduce transmission noise.

[0040] In this embodiment, the output shaft 2031 passes through the shaft hole of the lower conical disk 204, the central through hole of the protective cover 205, and the inner side of the shaft hole of the upper conical disk 206, i.e. the inside of the linkage cylinder 2063. The output shaft 2031 and each component are supported by bearings or clearance fit to ensure no interference during rotation and sliding.

[0041] In this embodiment, the central drive shaft of the drying rack 208 is fixedly installed in the middle section of the output shaft 2031 via a key connection, and is located above the lower conical disc 204 and outside the protective cover 205, rotating synchronously with the output shaft 2031. The mounting plate 209 is fixedly connected to the upper conical disc 206 via a linkage cylinder 2063, and rotates in the opposite direction with the upper conical disc 206, ultimately achieving precise synchronous reverse rotation between the drying rack 208 and the mounting plate 209, i.e., equal speed and opposite direction.

[0042] See appendix Figure 5 -Appendix Figure 8A second ring rail 2062 is provided on the outer wall of the upper conical disk 206 on the side away from the direction of gravity, and a second ring groove 2051 is provided on the top inner wall of the protective cover 205. The upper conical disk 206 is rotatably disposed in the second ring groove 2051 via the second ring rail 2062. A first ring rail 2042 is provided on the outer wall of the lower conical disk 204 on the side facing the direction of gravity, and a first ring groove 2024 is provided on the outer wall of the second sliding seat 202. The lower conical disk 204 is rotatably disposed in the first ring groove 2024 via the first ring rail 2042.

[0043] In this embodiment: the first ring rail 2042 is an annular protrusion structure, integrally formed on the outer wall of the lower conical disk 204 facing the direction of gravity, that is, the bottom outer periphery of the lower conical disk 204, and the material is the same as the body of the lower conical disk 204. The cross-section of the first ring rail 2042 is rectangular, and the outer peripheral surface and end face of the first ring rail 2042 are precision ground to reduce the coefficient of rotational friction.

[0044] In this embodiment: the first annular groove 2024 is an annular groove, formed on the outer periphery of the upper surface of the second sliding seat 202, that is, at the position corresponding to the lower conical disk 204, and the groove shape is adapted to the first annular rail 2042. The groove wall of the first annular groove 2024 is precision ground to ensure the coaxiality of the lower conical disk 204 when it rotates.

[0045] In this embodiment: the second annular rail 2062 is an annular protrusion structure, integrally formed on the outer wall of the upper conical disk 206 away from the direction of gravity, that is, on the top outer periphery of the upper conical disk 206. Its material is the same as the body of the upper conical disk 206, its structural parameters are symmetrical with the first annular rail 2042, and its surface is precision ground. The second annular groove 2051 is an annular recess, formed on the top inner wall of the protective cover 205, that is, at the position corresponding to the upper conical disk 206. The groove shape is adapted to the second annular rail 2062.

[0046] In this embodiment: the motor 203 is started, and its output shaft 2031 drives the lower conical disk 204 to rotate clockwise. The lower conical disk 204 rotates smoothly within the first annular groove 2024 of the second sliding seat 202 via the first annular rail 2042. The lower conical tooth 2041 engages with the linkage tooth 207 to drive the upper conical disk 206 to rotate counterclockwise. The upper conical disk 206 rotates synchronously and smoothly within the second annular groove 2051 of the protective cover 205 via the second annular rail 2062.

[0047] The upper conical disc 206 drives the mounting disc 209 to rotate counterclockwise via the linkage cylinder 2063, while the drying rack 208 rotates clockwise with the output shaft 2031, achieving synchronous counterclockwise rotation. At the same time, the ultraviolet lamp 2082 is turned on, and the condenser irradiates the optical fiber uniformly around its circumference and on its upper and lower surfaces.

[0048] See appendix Figure 8 and attached Figure 10The protective cover 205 has a through hole 2052 for the linkage cylinder 2063 to pass through; the second sliding seat 202 is equipped with a bearing 2021, and the output shaft 2031 is installed inside the bearing 2021.

[0049] In this embodiment: the through hole 2052 is located at the top center of the protective cover 205. It is a circular through hole with a diameter 0.3-0.5mm larger than the outer diameter of the linkage cylinder 2063, ensuring no interference when the linkage cylinder 2063 passes through and providing a sealing gap. The inner wall of the through hole 2052 is precision ground, and the upper and lower ends of the hole are chamfered to prevent friction between the linkage cylinder 2063 and the edge of the hole when it rotates.

[0050] In this embodiment, two annular sealing grooves are formed on the inner wall of the through hole 2052. The first sealing groove contains a Y-shaped silicone rubber sealing ring, which is interference-fitted with the outer wall of the linkage cylinder 2063 to achieve dynamic sealing. The second sealing groove contains a labyrinth sealing ring made of polytetrafluoroethylene, which forms a gap seal with the outer wall of the linkage cylinder 2063 and is filled with vacuum-compatible grease to block gas exchange between the vacuum chamber and the inside of the protective cover 205.

[0051] In this embodiment: Bearing 2021 is a deep groove ball bearing, model 6206-2RS, with an IP54 protection rating. There is one bearing, or two can be installed in series depending on the load requirements. It is installed in the central bearing housing of the second sliding seat 202 via an transition fit. The inner ring of bearing 2021 is fixedly connected to the lower section of the output shaft 2031, and the outer ring is tightly fitted to the inner wall of the bearing housing. A dust cover is provided at the bottom of the bearing housing to prevent impurities from entering the interior of bearing 2021.

[0052] See appendix Figure 4 -Appendix Figure 5 and attached Figure 10 -Appendix Figure 11 The second sliding seat 202 is provided with a slide rail 2022, and the inner wall of the processing box 1 is provided with a second slide groove 104. The second sliding seat 202 is slidably disposed in the second slide groove 104 via the slide rail 2022. The first sliding seat 201 includes a slider 2011 slidably disposed in the first slide groove 103, and a sealing plate 2012 covering the first slide groove 103 is provided on the slider 2011.

[0053] In this embodiment: the slider 2011 is a T-shaped structural component made of high-strength aluminum alloy and anodized. The main body of the slider 2011 is embedded in the first groove 103 at the top of the processing box 1, with the sliding fit clearance controlled at 0.1-0.2mm. The vertical section of the slider 2011 penetrates the first groove 103, and its top is integrally formed with or bolted to the sealing plate 2012, tightly fitting against the side wall of the first groove 103 to achieve dynamic sealing in the sliding direction.

[0054] In this embodiment: the sealing plate 2012 is a rectangular flat plate structure, the material is the same as that of the slider 2011, the thickness is 8-12mm, the size is larger than the opening size of the first slide groove 103, the length is 20-30mm longer than the first slide groove 103, the width is 10-15mm wider than the first slide groove 103, and it completely covers the top opening of the first slide groove 103.

[0055] In this embodiment: the second sliding seat 202 achieves linear guided sliding through the embedded cooperation of the slide rail 2022 and the second slide groove 104, forming a synchronous upper and lower guide with the slider 2011 of the first sliding seat 201, ensuring the straightness of the rotating mechanism 2 when sliding as a whole, avoiding the relative positional shift of the drying rack 208 and the mounting plate 209 during the sliding process, and ensuring the accuracy of operation.

[0056] See appendix Figure 12 -Appendix Figure 13 The mounting cavity 2091 is provided with a positioning component 210, which is used to limit the magnetic shielding shell. The positioning component 210 includes a plurality of telescopic seats 2101 arranged at intervals. Each telescopic seat 2101 has a telescopic cavity 2102. A clamping seat 2103 is slidably arranged in the telescopic cavity 2102. A reset member 2104 is connected between the clamping seat 2103 and the inner wall of the telescopic cavity 2102. A lifting part 2105 is provided on the outer wall of the clamping seat 2103 facing the magnetic shielding shell.

[0057] In this embodiment, the positioning component 210 is embedded in each mounting cavity 2091 of the mounting plate 209. Its function is to realize the radial elastic clamping and axial lifting positioning of the magnetic shielding shell. Through the synergistic effect of the telescopic structure and the reset component 2104, it can adapt to magnetic shielding shells with different outer diameter specifications, and at the same time buffer the stress impact during the rotation and curing process to avoid rigid contact damage between the magnetic shielding shell and the optical fiber ring.

[0058] In this embodiment: the telescopic seat 2101 is a block-shaped structural component, made of high-strength engineering plastic or lightweight aluminum alloy, possessing wear resistance, temperature resistance, and low stress deformation characteristics. There are 3-4 telescopic seats 2101, evenly spaced along the circumferential direction of the inner wall of the mounting cavity 2091.

[0059] In this embodiment: the telescopic seat 2101 has a telescopic cavity 2102 on the side facing the center of the mounting cavity 2091. The telescopic cavity 2102 is a rectangular groove, and the inner wall of the cavity is precision ground to ensure that the clamping seat 2103 slides smoothly.

[0060] In this embodiment: the clamping seat 2103 is an integrated structure, made of the same material as the telescopic seat 2101. The clamping seat 2103 is partially slidably embedded in the telescopic cavity 2102, with the fitting clearance controlled at 0.05-0.1mm. The end of the clamping seat 2103 facing the magnetic shielding shell has an arc-shaped clamping surface, the curvature of which matches the outer wall of the magnetic shielding shell. A flexible buffer pad with a thickness of 1-2mm is attached to the clamping surface to avoid rigid contact with the magnetic shielding shell, while increasing friction and improving clamping stability.

[0061] In this embodiment: the reset component 2104 is a cylindrical compression spring, installed between the bottom of the telescopic cavity 2102 and the end face of the clamping seat 2103. The pre-compression of the reset component 2104 is 5-8mm, providing an elastic pre-tightening force of 0.5-2N, ensuring that the clamping seat 2103 always has a clamping tendency toward the center of the mounting cavity 2091. Through the extension and deformation of the spring, it can be adapted to magnetic shielding shells with an outer diameter of φ20-φ80mm, improving the versatility of the positioning component 210.

[0062] In this embodiment, the lifting part 2105 is an arc-shaped protrusion structure, integrally formed on the bottom of the outer wall of the clamping seat 2103 facing the magnetic shielding shell, smoothly transitioning with the clamping surface. Its material is the same as the main body of the clamping seat 2103, and its surface is covered with a flexible buffer pad identical to the clamping surface. Three to four lifting parts 2105 work together to form an annular lifting surface, providing axial support to the magnetic shielding shell and preventing axial displacement of the workpiece due to centrifugal force or vibration during rotation, thus achieving dual positioning of radial clamping and axial lifting.

[0063] In this embodiment: the magnetic shielding housing, after being glued and assembled, is placed from above the mounting cavity 2091. The bottom of the housing contacts the buffer pad of the supporting part 2105. The housing is pressed down, pushing the clamping seat 2103 to slide into the telescopic cavity 2102. The resetting member 2104 is compressed and generates an elastic reaction force. After the housing is in place, the elastic reaction force of the resetting member 2104 drives 3-4 clamping seats 2103 to clamp towards the center simultaneously. The buffer pad of the arc-shaped clamping surface fits tightly against the outer wall of the magnetic shielding housing, achieving radial positioning. At the same time, the supporting part 2105 assists in supporting the bottom of the housing, limiting axial displacement. The vacuum equipment 102 is started, and a vacuum is drawn to 10-50 mbar and held for 10-20 minutes to remove glue air bubbles.

[0064] In this embodiment: when the mounting plate 209 rotates, in order to prevent the fiber optic ring from shifting axially relative to the magnetic shielding housing under the action of centrifugal force, an annular guide ring sleeve structure is designed inside the magnetic shielding housing to limit the inner wall of the fiber optic ring so as to prevent the fiber optic ring from moving axially relative to the magnetic shielding housing during rotation.

[0065] See appendix Figure 14 -Appendix Figure 15The processing box 1 is rotatably equipped with a door panel 3, and the door panel 3 has an opening 302; the door panel 3 is equipped with a roller door assembly 303, which is used to open and close the opening 302.

[0066] In this embodiment, the rolling door assembly 303 enables partial opening during the preheating stage, which satisfies the need for manual loading of the magnetic shielding shell while avoiding rapid heat loss caused by fully opening the door panel 3, thus ensuring the temperature stability of the curing process.

[0067] In this embodiment: the door panel 3 is made of 304 stainless steel with an anodized surface, possessing high strength and thermal insulation properties. The door panel 3 is rotatably connected to the side wall of the processing box 1 via hinges. The hinges are made of stainless steel and equipped with dampers to achieve slow opening and closing of the door panel, avoiding sealing failure caused by impact.

[0068] In this embodiment, an annular sealing groove is provided on the inner edge of the door panel 3, and a silicone rubber vacuum sealing ring is built in. When the door panel 3 is completely closed, the sealing ring is tightly fitted with the sealing surface of the processing box 1 to ensure vacuum sealing.

[0069] In this embodiment: the opening 302 is located in the central area of ​​the door panel 3 and is a rectangular through hole with a diameter that meets the needs of the operator's hands and the magnetic shielding shell for entry and exit. The roller door assembly 303 is fixedly installed on the outside or inside of the door panel 3. Its core function is to enable the opening 302 to be partially opened, fully opened, and fully closed, adapting to the heat preservation operation requirements during the preheating stage.

[0070] See appendix Figure 14 -Appendix Figure 15 The rolling door assembly 303 includes retractable parts 3031 located on the upper and lower sides of the opening 302, and a blocking part 3032 is arranged between the two retractable parts 3031. The blocking part 3032 has a pick-up and put-out opening 3033. A first handle 2023 is provided on the second sliding seat 202. A second handle 301 is provided on the door panel 3. The processing box 1 also includes a control panel 101.

[0071] In this embodiment, the roller door assembly 303 adopts a design of double winding components 3031 and a blocking component 3032 with a pick-up and drop-off opening 3033, replacing the traditional single roller structure, realizing the precise opening and closing of the opening 302 and the partial pick-up and drop-off function, taking into account heat preservation, sealing and operational flexibility.

[0072] In this embodiment, the winding component 3031 is a cylindrical roller structure, and there are two of them, which are fixedly installed on the upper and lower sides of the opening 302 respectively through bearing seats. Each winding component 3031 is equipped with a manual drive knob, which is exposed on the outside of the roller door frame and connected to the roller shaft through gear transmission. Rotating the knob can wind up the blocking component 3032. The bearing seat of the winding component 3031 is filled with grease to ensure smooth rotation, and it is equipped with a pawl positioning mechanism to fix the blocking component 3032 at any winding position with a positioning accuracy of ≤5mm.

[0073] In this embodiment: the shielding member 3032 is made of high temperature resistant flexible composite material, such as stainless steel fiber cloth and polytetrafluoroethylene coating, with a thickness of 0.4-1mm. Its width is adapted to the width of the opening 302, and its length is greater than twice the height of the opening 302, so as to ensure that the opening 302 can be fully exposed when fully rolled up and fully blocked when fully released.

[0074] In this embodiment, the access port 3033 is located in the central area of ​​the shield 3032 and is a rectangular through-hole, the size of which is adapted to the access needs of the operator's hand and the magnetic shielding shell. The edges of the access port 3033 are treated with stainless steel edging to avoid wear on the flexible material, and an annular sealing strip is provided on the inner side of the edging. When the access port 3033 is in the operating position, the sealing strip can reduce heat loss and air leakage. By retracting the shield 3032, the access port 3033 can be raised and lowered without fully opening the door panel 3, further improving the heat preservation effect.

[0075] In this embodiment: the first handle 2023 is fixedly installed on the outer wall of the second sliding seat 202, that is, on the side near the door panel 3, and its surface is provided with anti-slip texture. The second handle 301 is fixedly installed on the outer wall of the door panel 3, and its material is the same as that of the first handle 2023, and its structure is strip-shaped or ring-shaped. The connection between the second handle 301 and the door panel 3 is provided with reinforcing ribs to prevent the door panel from deforming under force and affecting the sealing performance.

[0076] In this embodiment: the control panel 101 is fixedly installed on the outer wall of the processing box 1, using an embedded installation method. The outer shell of the control panel 101 is made of ABS engineering plastic, and the surface is coated with a waterproof and dustproof coating. The control panel 101 is operated via a touch screen. ① Vacuum system control; ② Rotation system control; ③ Curing system control; ④ Temperature control; ⑤ Data management and security protection.
