Description

Technical Field

[0001] This invention belongs to the field of laser welding, and specifically relates to a welding method, an intelligent welding system with infrared heating lamps, and infrared heating lamps. Background Technology

[0002] Infrared heating lamps are lamps that primarily radiate the infrared spectrum and are widely used in industrial heating, medical therapy, and security detection. They use tungsten filaments or semiconductor materials to excite infrared radiation, and are characterized by high energy conversion efficiency and strong penetration. Currently, in the production and processing of infrared heating lamps, laser welding machines and ion welding machines are commonly used to weld the lamp core and electrode plates together.

[0003] Current laser welding machines typically use high-energy infrared lasers (such as fiber lasers and YAG lasers), which are highly harmful to the eyes. Currently, laser welding machines on the market mainly rely on passive safety measures, such as requiring operators to wear special laser safety glasses, setting up fixed protective shields, or posting warning signs in the work area.

[0004] However, these traditional protective measures have significant limitations. First, specialized protective goggles are usually dark-colored, which severely reduces visibility and can easily lead to visual fatigue for operators with prolonged wear. Second, the wearing of protective goggles relies on the operator's conscientiousness and discipline; there is a risk of negligence or complacency during long work periods, resulting in incorrect wearing. Third, while fixed protective shields can isolate the laser, they can affect the ease of loading and unloading workpieces and reduce the flexibility of equipment operation. Furthermore, other support personnel or visitors in the work area may be exposed to the dangerous diffuse laser light if they are not wearing appropriate goggles or are not adequately warned. Summary of the Invention

[0005] To address the problems in related technologies, this invention proposes a welding method, an intelligent welding system for infrared heating lamps, and an infrared heating lamp, in order to overcome the aforementioned technical problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention discloses an infrared heating lamp, including a quartz lamp tube. Both ends of the quartz lamp tube are sealed and fixedly installed with end caps. A filament is fixedly installed inside the quartz lamp tube. A conductive sheet is installed inside the end cap. An external connecting wire is welded to the outer end of the conductive sheet. An internal connecting wire is welded to the other end of the conductive sheet. The internal connecting wire is electrically connected to the filament. A reflective coating is provided on one side inside the quartz lamp tube.

[0008] Furthermore, the filament is a tungsten filament, and the quartz lamp tube is filled with inert gas. The tungsten filament heats up and radiates infrared rays after being energized, thus performing infrared heating. The conductive sheet is a molybdenum sheet, which has good conductivity and high temperature resistance. It can not only conduct electricity for the filament, but also maintain stable performance at high temperatures when the filament is energized and heated, thereby improving the service life of the infrared heating lamp. The reflective coating can reflect and concentrate infrared rays when the infrared heating lamp is working, thereby improving the heating effect of the infrared heating lamp.

[0009] This invention relates to a welding method, the specific steps of which are as follows:

[0010] S1. Place the parts to be welded into the positioning fixture on the outside of the turntable;

[0011] S2. The rotary drive assembly drives the turntable to rotate, causing the turntable to move the positioning fixture on it in a circular motion. At this time, the positioning fixture outside the protective cabinet gradually rotates and moves towards the laser welding mechanism inside the protective cabinet. When the positioning fixture moves to the fixture inlet position, the automatic protective door inside the fixture inlet automatically opens, so that the positioning fixture can be moved through the fixture inlet and transported into the interior of the protective cabinet. At the same time, the turntable also drives the positioning fixture inside the protective cabinet to gradually move towards the outside of the protective cabinet. When the positioning fixture moves to the fixture outlet position, the automatic protective door inside the fixture outlet automatically opens, so that the positioning fixture can be moved through the fixture outlet and transported to the outside of the protective cabinet.

[0012] S3. When the positioning fixture on the outside of the protective cabinet is moved and transported to the outermost side of the welding workbench, the positioning fixture is loaded and unloaded. At this time, the positioning fixture on the inside of the protective cabinet is moved and transported to the bottom of the laser welder, and the automatic protective doors in the fixture inlet and fixture outlet are both closed.

[0013] S4. The position of the laser welder is adjusted by the position adjustment component so that the laser welder is aligned with the welding point of the part, so that the part in the positioning fixture can be laser welded by the laser welder.

[0014] Furthermore, in step S2, when the turntable drives the positioning fixture to move from the outside to the inside through the fixture inlet, the door opening and closing assembly, driven by the transmission assembly, first drives the door panels on both sides of the door frame to rotate inward synchronously to open, thus avoiding the positioning fixture. Then, the door opening and closing assembly drives the door panels on both sides of the door frame to rotate in the opposite direction synchronously to reset and close.

[0015] When the turntable drives the positioning fixture to move from the inside to the outside and passes through the fixture outlet, the door opening and closing assembly, driven by the transmission assembly, first drives the door panels on both sides of the door frame to rotate outward synchronously to open and avoid the positioning fixture. Then, the door opening and closing assembly drives the door panels on both sides of the door frame to rotate in the opposite direction synchronously to reset and close.

[0016] Furthermore, when the door opening and closing assembly is working, the reciprocating drive unit first drives the main pulley to rotate, and then drives the main pulley to rotate in the opposite direction to reset. When the main pulley rotates, it cooperates with the auxiliary pulley to drive the conveyor belt to move, so that the conveyor belt drives the two translation racks on it to move in parallel. At this time, the translation rack drives the corresponding driven gear to rotate, and then the driven gear drives the corresponding door panel to rotate and open through the connecting shaft.

[0017] When the main pulley rotates in the reverse direction to reset, it works with the auxiliary pulley to drive the conveyor belt to move in the reverse direction, so that the conveyor belt drives the two translation racks on it to move in the reverse direction to reset. At this time, the translation racks drive the corresponding driven gears to rotate in the reverse direction, and then the driven gears drive the corresponding door panels to rotate in the reverse direction to close through the connecting shaft.

[0018] An intelligent welding system for infrared heating lamps includes an intelligent controller and a laser welding device. The intelligent controller is signal-connected to the laser welding device so that the intelligent controller can drive the laser welding device to perform intelligent welding on the infrared heating lamps.

The rotary drive component can drive the turntable to rotate, so that the turntable drives the multiple positioning fixtures on it to move sequentially under the laser welder.

[0020] The welding workbench is also equipped with a protective mechanism, which includes a protective cabinet. The protective cabinet is set on the surface of the welding workbench and encloses the laser welding mechanism. One side of the turntable is located outside the protective cabinet, and the other side of the turntable is located inside the protective cabinet. The protective cabinet has a fixture inlet and a fixture outlet located on the circumferential movement path of the positioning fixture.

[0023] A lifting drive slide rail cylinder is fixedly installed on the front and rear translation slide block. A lifting slide block is slidably installed on the lifting drive slide rail cylinder, and the lifting slide block is fixedly connected to the telescopic end of the lifting drive slide rail cylinder. A left and right drive slide rail cylinder is fixedly installed on the lifting slide block. A left and right translation slide block is slidably installed on the left and right drive slide rail cylinder, and the left and right translation slide block is fixedly connected to the telescopic end of the left and right drive slide rail cylinder. An angle adjustment plate is fixedly installed on the left and right translation slide block. The laser welder is tilted and fixedly installed on the angle adjustment plate.

[0024] Furthermore, the automatic protective door includes a door frame, a door opening and closing assembly, and a transmission assembly. The door frame is fixedly installed on the outer wall of the protective cabinet. Door panels are rotatably installed on both sides inside the door frame. The door opening and closing assembly can be connected to a turntable via the transmission assembly. When the turntable rotates and moves the positioning fixture on it past the position of the automatic protective door, the door opening and closing assembly can rotate and open the door panels on both sides of the door frame under the drive of the transmission assembly. The door opening and closing assembly can also rotate and close the door panels on both sides of the door frame after the positioning fixture has moved past the position of the automatic protective door.

[0025] Furthermore, the door opening and closing assembly includes a main pulley, a secondary pulley, two sets of connecting shafts, and a reciprocating drive unit. The two sets of connecting shafts are respectively fixedly installed on the outer side of the top of the two door panels, and a driven gear is fixedly installed on the upper end of each of the two connecting shafts.

[0026] The main pulley and the auxiliary pulley are rotatably mounted on both sides of the door frame, and a conveyor belt is driven between the main pulley and the auxiliary pulley. A translation rack is fixedly mounted on both the upper and lower sides of the conveyor belt, and the two translation racks are respectively meshed with the corresponding driven gears for transmission.

[0027] The reciprocating drive unit is connected between the transmission assembly and the main pulley, so that the reciprocating drive unit can drive the main pulley to rotate back and forth under the transmission of the transmission assembly.

[0028] Furthermore, the reciprocating drive unit includes an eccentric shaft, a lifting rack, and a rotating shaft. The eccentric shaft is rotatably mounted on the door frame, and one end of the eccentric shaft is connected to a transmission assembly. A connecting rod is rotatably mounted on the eccentric part of the eccentric shaft.

The rotating shaft is fixedly mounted on one end of the main pulley, and a drive gear that meshes and drives with the lifting rack is fixedly mounted on the rotating shaft.

[0029] Furthermore, the transmission assembly includes multiple arc-shaped racks, a transmission shaft, and a driven bevel gear. The multiple arc-shaped racks are circumferentially distributed and fixedly installed on the outer ring of the turntable, and each arc-shaped rack corresponds to a corresponding positioning fixture. The transmission shaft is rotatably installed on the inner wall of the door frame. A transmission gear capable of meshing and transmitting power with the arc-shaped racks is fixedly installed at the bottom end of the transmission shaft. A transmission bevel gear is fixedly installed at the top end of the transmission shaft. The driven bevel gear is fixedly installed on the eccentric shaft, and the transmission bevel gear and the driven bevel gear are meshed and transmitted power together.

[0030] The present invention has the following beneficial effects:

[0031] 1. In this invention, a protective cabinet is provided on the welding worktable, and the laser welding mechanism is located inside the protective cabinet, thereby isolating and protecting the laser during welding, greatly improving welding safety. A turntable is also provided on the welding worktable, with positioning fixtures mounted on it. One side of the turntable is located outside the protective cabinet, and the other side is located inside. The protective cabinet has an opening for the positioning fixtures to enter and exit. The rotation of the turntable can move the positioning fixtures and their internal parts into the protective cabinet for welding, or move them outside for loading and unloading, making the welding and loading / unloading processes more convenient. Furthermore, multiple positioning fixtures are provided on the turntable. When one set of positioning fixtures moves to the welding station for welding, another set moves to the loading / unloading station for loading and unloading, allowing for simultaneous welding and loading / unloading operations, which improves welding efficiency.

[0032] 2. In this invention, automatic protective doors are installed in both the fixture inlet and fixture outlet of the protective cabinet. When laser welding is being performed, the automatic protective doors are in a closed state, thereby shielding the fixture inlet and fixture outlet and preventing the laser from escaping from the fixture inlet and fixture outlet during welding, thus further improving the safety of welding. In addition, the automatic protective doors can automatically open when the positioning fixture moves through the fixture inlet and fixture outlet, so that the positioning fixture can move normally through the fixture inlet and fixture outlet, ensuring that the positioning fixture movement and transportation process is normal and stable.

[0033] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0051] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0052] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0053] Example 1

[0054] Please see Figures 5-8As shown, this embodiment discloses an intelligent welding system for infrared heating lamps, including an intelligent controller and a laser welding device. The intelligent controller is signal-connected to the laser welding device so that the intelligent controller can drive the laser welding device to perform intelligent welding on the infrared heating lamp.

[0055] The laser welding equipment includes a welding worktable 1, on which a fixture mechanism 2 and a laser welding mechanism 4 are installed. The laser welding mechanism 4 includes a position adjustment component and a laser welder 49. The position adjustment component can adjust the orientation of the laser welder 49. The fixture mechanism 2 includes a rotary drive component and a turntable 21. The turntable 21 is rotatably mounted on the table surface of the welding worktable 1. Multiple positioning fixtures 22 are fixedly installed on the turntable 21. The rotary drive component can drive the turntable 21 to rotate, so that the turntable 21 drives the multiple positioning fixtures 22 on it to move sequentially under the laser welder 49.

[0056] The welding workbench 1 is also equipped with a protective mechanism 3, which includes a protective cabinet 31. The protective cabinet 31 is set on the table surface of the welding workbench 1 and encloses the laser welding mechanism 4. One side of the turntable 21 is located outside the protective cabinet 31, and the other side of the turntable 21 is located inside the protective cabinet 31. The protective cabinet 31 has a fixture inlet 35 and a fixture outlet 36 located on the circumferential movement path of the positioning fixture 22. Automatic protective doors are installed in both the fixture inlet 35 and the fixture outlet 36. The automatic protective doors can be automatically opened when the positioning fixture 22 moves through the fixture inlet 35 and the fixture outlet 36.

[0057] Specifically, when using the laser welding equipment, the parts to be welded are first clamped and placed in the positioning fixture 22 outside the turntable 21. Then, the turntable 21 is driven to rotate by the rotary drive assembly, causing the positioning fixture 22 on the turntable 21 to move in a circular motion. At this time, the positioning fixture 22 outside the protective cabinet 31 gradually rotates and moves towards the laser welding mechanism 4 inside the protective cabinet 31. When the positioning fixture 22 moves to the fixture inlet 35, the automatic protective door inside the fixture inlet 35 automatically opens, so that the positioning fixture 22 can be moved and transported into the interior of the protective cabinet 31 through the fixture inlet 35. At the same time, the turntable 21 also drives the positioning fixture 22 inside the protective cabinet 31 to gradually move towards the outside of the protective cabinet 31. When the positioning fixture 22 moves to the position of the laser welding mechanism 4 inside the protective cabinet 31, the laser welding mechanism 22 moves towards the outside of the protective cabinet 31. When the fixture is in position 36, the automatic protective door inside the fixture outlet 36 automatically opens, allowing the positioning fixture 22 to be moved and transported to the outside of the protective cabinet 31 through the fixture outlet 36. Then, the positioning fixture 22 on the outside of the protective cabinet 31 is moved and transported to the outermost side of the welding workbench 1, where loading and unloading of the positioning fixture 22 can be performed. Meanwhile, the positioning fixture 22 on the inside of the protective cabinet 31 is moved and transported to the bottom of the laser welder 49, and the automatic protective doors inside the fixture inlet 35 and fixture outlet 36 are both closed. Finally, the position of the laser welder 49 is adjusted by the position adjustment component so that the laser welder 49 is aligned with the welding point of the part, so that the part inside the positioning fixture 22 can be laser welded by the laser welder 49.

[0058] The system features a protective cabinet 31 that isolates and protects the laser during welding, significantly improving safety. The rotation of the turntable 21 moves the positioning fixture 22 and its internal parts inside the protective cabinet 31 for welding, or moves the positioning fixture 22 outside for loading and unloading, making the welding and loading / unloading processes more convenient. Furthermore, the turntable 21 is equipped with multiple positioning fixtures 22. When one set of positioning fixtures 22 moves to the welding station for welding, another set moves to the loading / unloading station for loading and unloading, allowing for simultaneous welding and loading / unloading operations, which is beneficial for improving efficiency. High welding efficiency; Automatic protective doors are installed in both the fixture inlet 35 and fixture outlet 36 of the protective cabinet 31. When laser welding is performed, the automatic protective doors are closed, thus shielding the fixture inlet 35 and fixture outlet 36 to prevent the laser from escaping from the fixture inlet 35 and fixture outlet 36 during welding, further improving the safety of welding. The automatic protective doors can also open automatically when the positioning fixture 22 moves through the fixture inlet 35 and fixture outlet 36, allowing the positioning fixture 22 to move normally through the fixture inlet 35 and fixture outlet 36, ensuring the normal and stable operation of the positioning fixture 22's movement and conveying process.

[0059] Example 2

[0060] Please see Figure 5 , Figure 11 As shown, the difference between this embodiment and the above embodiment is that the rotary drive assembly includes a bracket 23, which is fixedly installed inside the welding workbench 1. A motor 24 and a reduction gearbox 25 are fixedly installed on the top surface of the bracket 23. The turntable 21 is fixedly installed on the output shaft of the reduction gearbox 25. A driven wheel 28 is fixedly installed on the input shaft of the reduction gearbox 25. A driving wheel 26 is fixedly installed on the output shaft of the motor 24. The driving wheel 26 and the driven wheel 28 are connected by a transmission belt 27.

[0061] When the rotary drive assembly is working, the motor 24 drives the drive wheel 26 to rotate, and the drive wheel 26 then drives the driven wheel 28 to rotate through the transmission belt 27. After that, the driven wheel 28 drives the turntable 21 to rotate after passing through the reduction gearbox 25, so that the turntable 21 drives the positioning fixture 22 on it to make circular motion.

[0062] Example 3

[0063] Please see Figure 9 , Figure 10 As shown, the difference between this embodiment and the above embodiment is that the position adjustment component includes a support 41, which is fixedly installed on the surface of the welding workbench 1. A front-to-back drive slide rail cylinder 42 is fixedly installed on the support 41. A front-to-back translation slide block 43 is slidably installed on the front-to-back drive slide rail cylinder 42, and the front-to-back translation slide block 43 is fixedly connected to the telescopic end of the front-to-back drive slide rail cylinder 42. A lifting drive slide rail cylinder 44 is fixedly installed on the front-to-back translation slide block 43. A lifting slide block 45 is slidably mounted on the upper part of the device, and the lifting slide block 45 is fixedly connected to the telescopic end of the lifting drive slide rail cylinder 44. A left and right drive slide rail cylinder 46 is fixedly mounted on the lifting slide block 45. A left and right translation slide block 47 is slidably mounted on the left and right drive slide rail cylinder 46, and the left and right translation slide block 47 is fixedly connected to the telescopic end of the left and right drive slide rail cylinder 46. An angle adjustment plate 48 is fixedly mounted on the left and right translation slide block 47. The laser welder 49 is tilted and fixedly mounted on the angle adjustment plate 48.

[0064] Among them, the front and rear drive slide rail cylinder 42 can drive the front and rear translation slide 43 to move back and forth above the welding worktable 1, thereby driving the laser welder 49 to move back and forth for adjustment. The lifting drive slide rail cylinder 44 can drive the lifting slide 45 to move up and down, thereby driving the laser welder 49 to move up and down for adjustment. The left and right drive slide rail cylinder 46 can drive the left and right translation slide 47 to move back and forth above the welding worktable 1, thereby driving the laser welder 49 to move left and right for adjustment. By adjusting the laser welder 49 back and forth, up and down, and left and right, the position of the laser welder 49 can be adjusted so that the welding port of the laser welder 49 can be aligned with the welding point of the part in the positioning fixture 22, and the part can be precisely welded.

[0065] Example 4

[0066] Please see Figures 5-8 , Figure 12 , Figure 13 As shown, the difference between this embodiment and the above embodiment is that the automatic protective door includes a door frame 32, a door opening and closing assembly, and a transmission assembly. The door frame 32 is fixedly installed on the outer wall of the protective cabinet 31. Door panels 33 are rotatably installed on both sides inside the door frame 32. The door opening and closing assembly can be connected to the turntable 21 through the transmission assembly so that when the turntable 21 rotates and drives the positioning fixture 22 on it to move past the position of the automatic protective door, the door opening and closing assembly can rotate and open the door panels 33 on both sides of the door frame 32 under the drive of the transmission assembly. The door opening and closing assembly can also rotate and close the door panels 33 on both sides of the door frame 32 after the positioning fixture 22 has moved past the position of the automatic protective door.

[0067] Specifically, when the turntable 21 drives the positioning fixture 22 to move from the outside to the inside through the fixture inlet 35, the door opening and closing assembly, driven by the transmission assembly, first drives the door panels 33 on both sides of the door frame 32 to rotate inward synchronously to open, avoiding the positioning fixture 22. Then, the door opening and closing assembly drives the door panels 33 on both sides of the door frame 32 to rotate in the opposite direction synchronously to reset and close. When the turntable 21 drives the positioning fixture 22 to move from the inside to the outside through the fixture outlet 36, the door opening and closing assembly, driven by the transmission assembly, first drives the door panels 33 on both sides of the door frame 32 to rotate outward synchronously to open, avoiding the positioning fixture 22. Then, the door opening and closing assembly drives the door panels 33 on both sides of the door frame 32 to rotate in the opposite direction synchronously to reset and close.

[0068] The door opening and closing mechanism, through the cooperation of the door opening and closing assembly and the transmission assembly, can automatically drive the door panel 33 to rotate and open when the positioning fixture 22 moves through the fixture inlet 35 and the fixture outlet 36. It can also drive the door panel 33 to rotate in the opposite direction and reset and close after the positioning fixture 22 has passed through the fixture inlet 35 and the fixture outlet 36, thus making the opening and closing process of the door panel 33 more convenient and faster.

[0069] Example 5

[0070] Please see Figures 5-8 , Figures 12-15As shown, the difference between this embodiment and the above embodiment is that the door opening and closing assembly includes a main pulley 317, an auxiliary pulley 318, two sets of connecting shafts 320, and a reciprocating drive unit. The two sets of connecting shafts 320 are respectively fixedly installed on the outer side of the top of the two door panels 33, and a driven gear 38 is fixedly installed on the upper end of each of the two connecting shafts 320. The main pulley 317 and the auxiliary pulley 318 are respectively rotatably installed on both sides of the door frame 32, and a conveyor belt 319 is driven between the main pulley 317 and the auxiliary pulley 318. Translation racks 321 are fixedly installed on the upper and lower sides of the conveyor belt 319, and the two translation racks 321 are respectively meshed with the corresponding driven gears 38 for transmission. The reciprocating drive unit is driven between the transmission assembly and the main pulley 317, so that the reciprocating drive unit can drive the main pulley 317 to reciprocate under the transmission of the transmission assembly.

[0071] When the door opening and closing assembly is working, the reciprocating drive unit first drives the main pulley 317 to rotate, and then drives the main pulley 317 to rotate in the opposite direction to reset. When the main pulley 317 rotates, it cooperates with the auxiliary pulley 318 to drive the conveyor belt 319 to move, so that the conveyor belt 319 drives the two translation racks 321 on it to move in parallel. At this time, the translation racks 321 drive the corresponding driven gears 38 to rotate, and then the driven gears 38 drive the corresponding door panels 33 to rotate and open through the connecting shaft 320. When the main pulley 317 rotates in the opposite direction to reset, it cooperates with the auxiliary pulley 318 to drive the conveyor belt 319 to move in the opposite direction, so that the conveyor belt 319 drives the two translation racks 321 on it to move in the opposite direction to reset. At this time, the translation racks 321 drive the corresponding driven gears 38 to rotate in the opposite direction, and then the driven gears 38 drive the corresponding door panels 33 to rotate in the opposite direction to close through the connecting shaft 320.

[0072] The reciprocating drive unit, the conveyor belt 319, and the two sets of translation racks 321 and driven gears 38 work together to simultaneously drive the left and right door panels 33 to rotate and open to the same side, or to rotate and reset and close in the opposite direction, thus realizing the automatic opening and closing of the door panels 33.

[0073] Example 6

[0074] Please see Figures 5-8 , Figures 12-15As shown, the difference between this embodiment and the above embodiment is that the reciprocating drive unit includes an eccentric shaft 311, a lifting rack 314 and a rotating shaft 315. The eccentric shaft 311 is rotatably mounted on the door frame 32. One end of the eccentric shaft 311 is connected to the transmission assembly. A connecting rod 313 is rotatably mounted on the eccentric part of the eccentric shaft 311. The lifting rack 314 is slidably mounted on the inner wall of the door frame 32, and the bottom end of the lifting rack 314 is rotatably connected to the connecting rod 313. The rotating shaft 315 is fixedly mounted on one end of the main pulley 317. A drive gear 316 that meshes and is connected to the lifting rack 314 is fixedly mounted on the rotating shaft 315.

[0075] The transmission assembly includes multiple arc-shaped racks 34, a transmission shaft 39, and a driven bevel gear 312. The multiple arc-shaped racks 34 are circumferentially distributed and fixedly installed on the outer ring of the turntable 21, and each arc-shaped rack 34 corresponds to a corresponding positioning fixture 22. The transmission shaft 39 is rotatably installed on the inner wall of the door frame 32. The bottom end of the transmission shaft 39 is fixedly installed with a transmission gear 37 that can mesh and transmit power with the arc-shaped racks 34. The top end of the transmission shaft 39 is fixedly installed with a transmission bevel gear 310. The driven bevel gear 312 is fixedly installed on the eccentric shaft 311, and the transmission bevel gear 310 and the driven bevel gear 312 mesh and transmit power with each other.

[0076] When the positioning fixture 22 rotates with the turntable 21 to the position of the automatic protective door, the arc-shaped rack 34 on the outer side of the positioning fixture 22 meshes with the transmission gear 37 below the door frame 32. Then, as the turntable 21 continues to rotate, the arc-shaped rack 34 meshes with and drives the transmission gear 37 to rotate. The transmission gear 37 then drives the transmission shaft 39 and the transmission bevel gear 310 to rotate. After that, the transmission bevel gear 310 meshes with and drives the driven bevel gear 312 to rotate, thereby driving the eccentric shaft 311 to rotate. When the eccentric shaft 311 rotates, it first pushes the lifting rack 314 upward through the connecting rod 313. At this time, the lifting rack 314 drives the drive gear When wheel 316 rotates, drive gear 316 drives main pulley 317 to rotate via shaft 315, thereby driving door panel 33 to gradually rotate and open. When eccentric shaft 311 rotates 180°, lifting rack 314 moves to its highest position, and door panel 33 rotates to its maximum extent. Then, as eccentric shaft 311 continues to rotate, it pulls lifting rack 314 down to reset via connecting rod 313. At this time, lifting rack 314 drives drive gear 316 to rotate in the opposite direction, and drive gear 316 drives main pulley 317 to rotate in the opposite direction via shaft 315, thereby driving door panel 33 to gradually rotate in the opposite direction and close.
