[0002] In industrial production, especially for workpieces formed at high temperatures, such as plastic profiles and metal castings, cooling treatment is often required to ensure the quality of subsequent processing or direct use. If high-temperature workpieces are not sufficiently cooled, it will not only prevent subsequent cutting, grinding, and assembly processes from proceeding smoothly, but may also lead to quality defects such as deformation and cracking due to incomplete release of thermal stress, seriously affecting the product qualification rate. At the same time, for some high-temperature workpieces, such as resin sand castings and high-temperature reduced iron pellets, oxidation and adhesion problems must be avoided during the cooling process, further raising the requirements for the cooling process.
[0003] After high-temperature forming, the workpieces are mostly transported by horizontal or inclined conveyor belts, and cooled by natural or forced air cooling.
[0004] In existing technologies, the contact area between high-temperature formed workpieces and air is limited during transportation, resulting in excessively long cooling times. To ensure sufficient cooling effect, a long transportation path is often required, which leads to a large footprint of the workpiece transportation line. Furthermore, when subsequent processes experience short pauses or speed adjustments, the transported workpieces cannot be buffered in time, which can easily cause production interruptions or workpiece accumulation, affecting the continuity and stability of overall production.

[0015] This invention provides a continuous cooling buffer conveying mechanism. It offers the following advantages: This continuous cooling buffer conveying mechanism, through the cooperation of vertical frames, horizontal frames, buffer conveying components, material transfer components, and air-cooling components, adopts a design combining vertical layered conveying and air-cooling. It continuously conveys, efficiently cools, and dynamically buffers high-temperature workpieces in vertical space, significantly shortening the path length required for traditional horizontal conveying and reducing the equipment's footprint. Furthermore, by intelligently controlling the workpiece conveying speed and temporary storage state, it effectively buffers differences in production rhythm between preceding and following processes, avoiding production interruptions or workpiece accumulation due to subsequent process pauses or speed adjustments. During the vertical conveying or buffering of workpieces, the directional airflow of cooled air, after heat exchange and cooling, blows onto the workpiece surface, improving the cooling efficiency and quality of the high-temperature workpieces.

[0016] Through the coordination of the crossbeam, the moving seat, the translation cylinder, the first pressing clamping cylinder, the second pressing clamping cylinder, the buffer, and the laser rangefinder, when the moving seat moves to the next gripping position, the buffer cushions the impact force on the moving seat, preventing the moving seat from rigidly colliding with the end of the crossbeam due to inertia, thus improving the stability of workpiece conveying. By limiting the moving seat and pressing down to fix the workpiece, displacement of the workpiece due to external vibration or its own gravity during the gripping process can be prevented, ensuring the stability and positioning accuracy of the workpiece at the gripping position. This helps to improve the stability and positioning accuracy of workpiece conveying, providing reliable positional assurance for subsequent gripping processes. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] In existing technologies, the contact area between high-temperature formed workpieces and air is limited during transportation, resulting in excessively long cooling times. To ensure sufficient cooling effect, a long transportation path is often required, which leads to a large footprint of the workpiece transportation line. Furthermore, when subsequent processes experience short pauses or speed adjustments, the transported workpieces cannot be buffered in time, which can easily cause production interruptions or workpiece accumulation, affecting the continuity and stability of overall production.
[0021] In view of this, the present invention provides a continuous cooling buffer conveying mechanism. Through the cooperation of the vertical frame, horizontal frame, buffer conveying component, material transfer component and air cooling component, it adopts a design that combines vertical layered conveying with air cooling to achieve continuous conveying, efficient cooling and dynamic buffering of high-temperature workpieces in vertical space. It significantly shortens the path length required by traditional horizontal conveying and significantly reduces the equipment footprint. By intelligently controlling the workpiece conveying speed and temporary storage state, it effectively buffers the difference in production rhythm between the preceding and following processes, avoiding production interruption or workpiece accumulation due to subsequent process stoppages or speed adjustments. Furthermore, during the vertical conveying or buffering of workpieces, by blowing the cooled cold air through heat exchange onto the workpiece surface, it improves the cooling efficiency and cooling quality of high-temperature workpieces, thereby enhancing the continuity and stability of overall production and meeting the dual requirements of high-precision production for workpiece temperature and production rhythm.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Depend on Figure 1-7 It is known that a continuous cooling buffer conveying mechanism includes a vertical frame 1, a horizontal frame 2 is provided on one side of the bottom of the vertical frame 1, and the continuous cooling buffer conveying mechanism also includes a buffer conveying component 3, a material transfer component 4 and an air cooling component 5. The buffer conveying component 3 is located inside the vertical frame 1; the material transfer component 4 is located on the top of the horizontal frame 2; and the air cooling component 5 is located on one side of the vertical frame 1. The buffer conveying component 3 adopts a vertical layered conveying method to continuously convey and temporarily store the workpiece inside the vertical frame 1. The air cooling component 5 continuously cools the workpiece during the conveying process. After the workpiece is conveyed to the bottom of the vertical frame 1, the material transfer component 4 moves the workpiece to the other side of the horizontal frame 2. In the specific implementation process, it is worth noting that the cooperation between the vertical frame 1 and the horizontal frame 2 forms the main support frame of the cooling buffer conveying mechanism, providing the installation foundation for the buffer conveying component 3, the transfer component 4, and the air-cooling component 5. The buffer conveying component 3 adopts a vertical layered design. The robot gripper places the high-temperature workpieces it grips into the feed position of the conveyor line located at the top of the vertical frame 1, and supports them on both sides of the bottom of the high-temperature workpieces. The workpieces are driven vertically downward along the interior of the vertical frame 1 by a circulating chain. According to the production rhythm, the running speed and start / stop status of the chain can be controlled to achieve layered temporary storage of multiple sets of workpieces in the vertical direction, effectively dealing with speed fluctuations in subsequent processes. The transfer component 4 is used to transfer the workpieces conveyed to the bottom of the vertical frame 1 to the waiting gripping position on the other side of the horizontal frame 2, providing precise positioning for the robot gripping in the next process. During the vertical conveying of the workpieces, the air-cooling component 5 cools the air that has undergone heat exchange and cooling. Directional airflow is blown onto the workpiece surface, and the high-temperature workpiece is cooled by air in the vertical conveying path. Through the cooperation between the vertical frame 1, horizontal frame 2, buffer conveying component 3, material transfer component 4 and air cooling component 5, a design combining vertical layered conveying and air cooling is adopted to realize continuous conveying, efficient cooling and dynamic buffering of high-temperature workpieces in vertical space. This significantly shortens the path length required by traditional horizontal conveying and significantly reduces the equipment footprint. By intelligently controlling the workpiece conveying speed and temporary storage status, the difference in production rhythm between the preceding and following processes is effectively buffered, avoiding production interruption or workpiece accumulation due to subsequent process stoppages or speed adjustments. Furthermore, during the vertical conveying or buffering of workpieces, the directional airflow of cooled air after heat exchange is blown onto the workpiece surface to improve the cooling efficiency and cooling quality of high-temperature workpieces, thereby improving the continuity and stability of overall production and meeting the dual requirements of high-precision production for workpiece temperature and production rhythm. Furthermore, the buffer conveying assembly 3 includes a drive shaft 31, a first sprocket 32, a first chain 33, a workpiece support plate 34, a first positioning support 35, a drive assembly 36, and a conveying sensing assembly 37. Two sets of drive shafts 31 are rotatably connected to both sides of the vertical frame 1. The first sprocket 32 is fixedly connected to both ends of the outer wall of the drive shaft 31. Multiple first chains 33 are meshed with the outer walls of corresponding upper and lower first sprockets 32. Two sets of workpiece support plates 34 are equidistantly fixedly connected to the sides of adjacent first chains 33. The first positioning support 35 is fixedly connected to both sides of the workpiece support plate 34. The drive assembly 36 is located on one side of the top of the vertical frame 1. The conveying sensing assembly 37 is located on both sides of the vertical frame 1. The drive assembly 36 drives the two sets of drive shafts 31 to rotate, causing the first sprocket 32 and the first chain 33 to rotate, enabling the two sets of workpiece support plates 34 to carry the workpieces and move them downwards, achieving vertical layered conveying of the workpieces. The conveying sensing assembly 37 monitors the position information of the workpieces in real time at specific locations. In the specific implementation process, it is worth noting that, through the cooperation between the drive shaft 31, the first sprocket 32, the first chain 33, the workpiece support plate 34, and the first positioning support 35, two sets of parallel vertical conveying chain groups are formed inside the vertical frame 1. The workpiece support plate 34 is evenly distributed between the two first chains 33 on the same side, and the two conveying chain groups maintain synchronous reverse rotation during operation, so that the workpiece support plate 34 on both sides is always in a horizontal state during the workpiece support process. The first positioning support 35 limits and supports the bottom sides of the workpiece, ensuring the stability of the workpiece during vertical conveying and preventing it from shifting or tilting during conveying. The drive component 36 is used to drive the two sets of parallel vertical conveying chain groups to rotate synchronously in opposite directions. The conveying sensing component 37 is used to monitor the position information of the workpiece in real time at a specific position, including whether the workpiece has entered the feeding position, whether it has reached the discharging position, and whether it has reached the grasping position, so that the system can accurately control the start and stop of the drive component 36 and the grasping action of the robot gripper based on the monitoring results, ensuring the orderly progress of the entire conveying process. Furthermore, the drive assembly 36 includes a servo motor 361, gears 362, a second sprocket 363, and a second chain 364. The servo motor 361 is fixedly connected to the top of the vertical frame 1 at one end of a drive shaft 31, and its output end is connected to the drive shaft 31. Two gears 362 are provided, located on the side of the vertical frame 1 away from the servo motor 361, respectively fixedly connected to the end of a drive shaft 31 and rotatably connected to the top of the vertical frame 1, and the two gears 362 mesh with each other. Two second sprockets 363 are provided, respectively fixedly connected to the gears 361. The outer wall of 362 and the end of the drive shaft 31 on the side away from the servo motor 361; the second chain 364 is meshed with the outer wall of the two second sprockets 363; wherein, the servo motor 361 drives the drive shaft 31 connected to it to rotate, and the gear 362 located at the end of the drive shaft 31 drives another gear 362 and the second sprocket 363 coaxial with it to rotate in the opposite direction. The second chain 364 and the other second sprocket 363 cause the drive shaft 31 on the side away from the servo motor 361 to rotate in the opposite direction, thereby realizing the reverse drive of the two sets of drive shafts 31; In the specific implementation process, it is worth noting that by controlling the servo motor 361 to drive one transmission shaft 31 to rotate, the gear 362 at the end of the transmission shaft 31 drives another gear 362 and the second sprocket 363 to rotate in the opposite direction. Then, the power is transmitted to the second sprocket 363 at the end of the transmission shaft 31 on the other side through the second chain 364, so that the two sets of transmission shafts 31 rotate in opposite directions, thereby driving the vertical conveyor chain groups on both sides to run synchronously in opposite directions. This ensures that the workpiece support plates 34 on both sides always remain horizontal when carrying the workpiece, and achieves stable vertical conveying of the workpiece. The specific model of the servo motor 361 is not limited, as long as it meets the usage requirements. Furthermore, the conveying sensing component 37 includes a first through-beam photoelectric sensor 371 and a second through-beam photoelectric sensor 372. The first through-beam photoelectric sensor 371 is fixedly connected to both sides of the top of the vertical frame 1. Two sets of the second through-beam photoelectric sensors 372 are provided and fixedly connected to both sides of the horizontal frame 2 respectively. The first through-beam photoelectric sensor 371 is used to detect whether the workpiece has entered the feeding position at the top of the vertical frame 1, and the second through-beam photoelectric sensor 372 is used to detect whether the workpiece has reached the discharge position at the bottom of the vertical frame 1, and to detect whether the workpiece has reached the position to be gripped in the next process. In the specific implementation process, it is worth noting that the first pair of photoelectric sensors 371 are installed on both sides of the top feeding position of the vertical frame 1. When the gripper of the loading robot places the high-temperature workpiece on the workpiece support plate 34, the workpiece will block the light from the first pair of photoelectric sensors 371. At this time, the sensor sends a signal to the control system to confirm that the workpiece has entered the feeding position. The control system then starts the drive assembly 36 to drive the workpiece downward. Two sets of second pair of photoelectric sensors 372 are installed at both ends of the horizontal frame 2, one of which is located at the bottom conveyor line discharge position of the vertical frame 1. It is used to detect whether the workpiece has been conveyed to the bottom discharge position. When the workpiece arrives, the second pair of photoelectric sensors 372 will detect whether the workpiece has been conveyed to the bottom discharge position. When the electrical sensor 372 is blocked, it sends a signal to the control system. The control system then stops the drive assembly 36 and starts the transfer assembly 4 to move the workpiece out. Another set of second through-beam photoelectric sensors 372 is installed on the side of the horizontal frame 2 away from the vertical frame 1. It is used to detect whether the transfer assembly 4 has accurately transported the workpiece to the position to be grasped. When the workpiece reaches the position, the sensor sends a signal to the robot control system of the next process to trigger the grasping action, thereby improving the positioning accuracy and automation efficiency during the workpiece transport process. The specific models of the first through-beam photoelectric sensor 371 and the second through-beam photoelectric sensor 372 are not limited, as long as they meet the usage requirements. Furthermore, the material transfer assembly 4 includes a movable base 41, a second positioning support 42, a translation cylinder 43, a slide rail 44, a sliding block 45, and a limiting assembly 46. The movable base 41 is located on the top of the cross frame 2; two sets of second positioning supports 42 are provided, fixedly connected to the top two sides of the movable base 41, and also connected to the first positioning support 35; the translation cylinder 43 is fixedly connected inside the cross frame 2 below the movable base 41, and its output end is fixedly connected to the bottom of the movable base 41; two slide rails 44 are provided, respectively... The top two sides of the cross frame 2 are fixedly connected; two sets of slide seats 45 are provided, which are fixedly connected to the bottom two sides of the movable seat 41 and slidably connected to the outer wall of the slide rail 44; the limiting components 46 are provided at both ends of the cross frame 2; wherein, the translation cylinder 43 drives the movable seat 41 to move horizontally along the slide rail 44, so that the second positioning support 42 is precisely docked with the first positioning support 35, realizing the smooth transition of the workpiece from the first positioning support 35 to the second positioning support 42, and moving the workpiece to the gripping position on the other side of the cross frame 2; In the specific implementation process, it is worth noting that the horizontal frame 2, the movable seat 41, the second positioning support 42, the translation cylinder 43, the slide rail 44, and the slide block 45 cooperate to form a horizontal workpiece transfer unit. When the workpiece is transported to the discharge position at the bottom of the vertical frame 1, the second through-beam photoelectric sensor 372 detects the workpiece and sends a signal to the control system. The control system stops the servo motor 361 and controls the translation cylinder 43 to start, driving the movable seat 41 to move along the slide rail 44 into the interior of the vertical frame 1, so that the second positioning support 42 at the top of the movable seat 41 is precisely aligned vertically with the first positioning support 35 on the workpiece support plate 34. The control system then restarts the servo motor 361. 61. As the workpiece is conveyed downwards, the bottom sides of the workpiece smoothly transition from the first positioning support 35 to the second positioning support 42. The control system then controls the translation cylinder 43 to drive the moving seat 41 to move along the slide rail 44 to the other side of the crossbeam 2, conveying the workpiece to the next process's gripping position. At this time, the second through-beam photoelectric sensor 372 located at this position is blocked by the workpiece and sends a position signal to the control system. The translation cylinder 43 stops moving, and the limit component 46 locks the position of the moving seat 41 to prevent it from shifting during the workpiece's waiting to be gripped, ensuring the stability of the workpiece at the gripping position. The specific model of the translation cylinder 43 is not limited, as long as it meets the usage requirements. Furthermore, the limiting component 46 includes a first pressing clamping cylinder 461, a second pressing clamping cylinder 462, a buffer 463, and a laser ranging sensor 464. Multiple first pressing clamping cylinders 461 are provided, fixedly connected to the outer wall of the horizontal frame 2 away from the vertical frame 1, and correspondingly positioned on the second positioning support 42. Two second pressing clamping cylinders 462 are provided, fixedly connected to both ends of the horizontal frame 2, with their output ends connected to the movable seat 41. Two buffers 463 are provided, fixedly connected to the horizontal frame 2 away from the vertical frame 1. One end is connected to the movable base 41; the laser rangefinder 464 is fixedly connected to the side of the vertical frame 1 away from the buffer 463, and is correspondingly set on the movable base 41; wherein, the first pressing clamping cylinder 461 presses down and fixes the workpiece after the workpiece moves to the position to be gripped, the second pressing clamping cylinder 462 limits the movable base 41 when it moves to the designated positions at both ends, the buffer 463 provides buffering and limiting functions for the movable base 41, and the laser rangefinder 464 monitors the real-time position information of the movable base 41 in real time; In the specific implementation process, it is worth noting that after the workpiece moves to the gripping position, the control system automatically controls the piston rod of the first pressing clamping cylinder 461 to extend upward, causing the pressing rod to rotate and press down to fix the workpiece, preventing the workpiece from shifting position due to external vibration or inertia during the waiting process, ensuring that the robot gripper can accurately grip in the next process. When the moving seat 41 moves along the slide rail 44 to the material picking position at the bottom of the vertical frame 1 or the gripping position on the other side of the horizontal frame 2, the control system automatically controls the piston rod of the second pressing clamping cylinder 462 to retract downward, causing the pressing rod to rotate and form a mechanical limit with the moving seat 41, locking the position of the moving seat 41, improving the positional accuracy during the workpiece transfer process, and the buffer 463 is installed. Installed at the end of the horizontal frame 2 away from the vertical frame 1, when the moving seat 41 carrying the workpiece moves quickly to the position to be gripped, the buffer 463 first contacts the moving seat 41, and absorbs the kinetic energy of the moving seat 41 through elastic buffering, avoiding rigid collision with the end of the horizontal frame 2, and reducing the impact during the operation of the equipment. The laser range sensor 464 is used to monitor the position coordinates of the moving seat 41 in real time and feed the data back to the control system, so that the system can adjust the operating parameters of the translation cylinder 43 in real time according to the position deviation, ensuring that the moving seat 41 can maintain high-precision position control during long-term operation. The specific models of the first pressing clamping cylinder 461, the second pressing clamping cylinder 462 and the laser range sensor 464 are not limited, as long as they meet the usage requirements. Furthermore, the air-cooled assembly 5 includes a fixed frame 51, a heat exchange core 52, an axial flow fan 53, and an angle adjustment assembly 54. Two fixed frames 51 are provided, which are fixedly connected to one side of the vertical frame 1, one above the other. Two heat exchange cores 52 are provided, which are rotatably connected to one side of the vertical frame 1, one above the other, and located below the fixed frames 51. The axial flow fan 53 is fixedly connected to the top of the heat exchange core 52. The angle adjustment assembly 54 is located on the side of the fixed frame 51 away from the vertical frame 1. During the vertical transport of the workpiece, the axial flow fan 53 is activated and introduces external cold air through the heat exchange core 52 to form a directional airflow that blows onto the surface of the workpiece to reduce the workpiece temperature. The angle adjustment assembly 54 can adjust the tilt angle of the heat exchange core 52 and the axial flow fan 53 according to actual needs. In the specific implementation process, it is worth noting that the fixed frame 51 is used to stably install the heat exchange core 52 and the axial flow fan 53 on one side of the vertical frame 1. The upper and lower sets of heat exchange cores 52 and axial flow fans 53 correspond to different height areas of the workpiece in the vertical conveying path, ensuring that the workpiece can be continuously subjected to the cold air throughout the entire conveying process. The external cold air first undergoes heat exchange treatment through the heat exchange core 52 to reduce the air temperature. Then, the driving force generated by the axial flow fan 53 blows the cooled air onto the surface of the workpiece, forming forced convection heat exchange, accelerating the dissipation of heat from the workpiece, improving the cooling efficiency of the workpiece, and thus shortening the time required for the workpiece to cool down. The angle adjustment component 54 is used to adjust the angle of the heat exchange core 52 and the axial flow fan 53, thereby adjusting the jet angle of the airflow. Furthermore, the angle adjustment assembly 54 includes an adjustment screw 541, a connecting seat 542, and a locking nut 543. The adjustment screw 541 is rotatably connected to the bottom of the fixed frame 51 on the side away from the vertical frame 1. The connecting seat 542 is rotatably connected to the side of the heat exchange core 52 away from the vertical frame 1 and is movably connected to the outer wall of the adjustment screw 541. Two locking nuts 543 are provided, which are threadedly connected to the upper and lower sides of the connecting seat 542 on the outer wall of the adjustment screw 541, respectively. By moving the connecting seat 542 up and down along the outer wall of the adjustment screw 541, the heat exchange core 52 is pulled to rotate around the connection point with the vertical frame 1. When the heat exchange core 52 is adjusted to the target angle, the locking nuts 543 on the upper and lower sides are tightened to adjust and fix the tilt angle of the heat exchange core 52 and the axial flow fan 53. In the specific implementation process, it is worth noting that when adjusting the angle of the heat exchange core 52, the operator can first loosen the locking nut 543, and rotate the adjusting screw 541 to make the connecting seat 542 move up and down along the outer wall of the screw, thereby driving the heat exchange core 52 to rotate around the connecting shaft with the vertical frame 1. After the airflow is adjusted to a suitable angle, the upper and lower locking nuts 543 are tightened to the upper and lower surfaces of the connecting seat 542 respectively to lock the tilt angle of the heat exchange core 52, thereby changing the air outlet direction of the axial flow fan 53. Furthermore, an infrared temperature sensor 55 is fixedly connected to the vertical frame 1 below the heat exchange core 52; In the specific implementation process, it is worth noting that the infrared temperature sensor 55 is used to monitor the surface temperature of the workpiece passing through the bottom area of the vertical frame 1 in real time, and feeds the temperature data back to the control system in real time so that the control system can automatically adjust the operating power of the axial flow fan 53 and the working efficiency of the heat exchange core 52, realize the intelligent adjustment of the cooling process, and avoid energy waste. The specific model of the infrared temperature sensor 55 is not limited, as long as it meets the usage requirements. The working principle of this application is illustrated below with a preferred embodiment: First, the high-temperature workpiece is picked up by the loading robot and placed on the workpiece support plate 34 at the top of the vertical frame 1. The first positioning support 35 located on both sides of the top of the two workpiece support plates 34 forms a limiting support at the bottom of the workpiece. The first through-beam photoelectric sensor 371 is blocked by the workpiece and sends a feeding signal to the control system. The control system then starts the servo motor 361. The servo motor 361 drives the two sets of transmission shafts 31 to rotate in opposite directions, thereby driving the vertical conveyor chain groups on both sides to run in opposite directions, ensuring that the workpiece support plate 34 always remains horizontal and carries the workpiece vertically downward along the vertical frame 1. During the workpiece conveying process, the control system dynamically adjusts the workpiece conveying rhythm by automatically adjusting the running speed and start / stop status of the servo motor 361 according to the difference in production rhythm between the preceding and following processes, ensuring that the production process between the preceding and following processes can be smoothly connected. In addition, the axial flow fan 53 introduces cooled air through the heat exchange core 52 to form a directional airflow that blows onto the workpiece surface, forcing convection heat exchange to reduce the workpiece temperature. When the workpiece is conveyed to the bottom of the vertical frame 1, the second through-beam photoelectric sensor 372 located at the bottom of the vertical frame 1 detects the workpiece and sends a signal to the control system. The system controls the servo motor 361 to stop running, and then starts the translation cylinder 43 to drive the moving seat 41 to move along the slide rail 44 into the vertical frame 1, so that the second positioning support 42 at the top of the moving seat 41 is precisely aligned with the first positioning support 35 on the workpiece support plate 34. The control system starts the servo motor 361 again, and the workpiece continues to move down. The bottom of the workpiece separates from the first positioning support 35 and smoothly transitions to the second positioning support. The workpiece is placed on support 42. Then, the control system automatically controls the translation cylinder 43 to drive the moving seat 41 to the other side of the crossbeam 2, transporting the workpiece to the next gripping position. The second through-beam photoelectric sensor 372 located at the gripping position is blocked and sends a position signal. The translation cylinder 43 stops moving, and the second pressing clamping cylinder 462 locks the position of the moving seat 41. At the same time, the first pressing clamping cylinder 461 presses down and fixes the workpiece, waiting for the robot to grip it in the next process. By repeating the above actions, the high-temperature workpiece can be continuously cooled, buffered and automatically transported.
