Description

An automated high-voltage switch operating mechanism clamping and flipping device and method Technical Field

[0001] This invention belongs to the field of high-voltage switch technology, specifically relating to an automated high-voltage switch operating mechanism clamping and flipping device and method. Background Technology

[0002] When assembling the high-voltage switch operating mechanism, it needs to be rotated 180 degrees and sealed with sealing strips. Currently, this process is primarily manual. The operating mechanism is hoisted using lifting equipment and then manually rotated. Due to the significant weight of the operating mechanism, manual rotation is very inconvenient, taking approximately ten minutes to rotate a single unit. Furthermore, manual operation presents technical challenges such as high risk and low efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an automated clamping and flipping device and method for high-voltage switch operating mechanisms, in order to solve the problems in the prior art where the operating mechanism itself is heavy, manual flipping is very inconvenient, the flipping operation of a single mechanism takes about ten minutes, and the technical defects of high risk and low efficiency due to manual operation.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] In a first aspect, an automated high-voltage switch operating mechanism clamping and flipping mechanism is provided, comprising:

[0006] A load-bearing device, on which a conveying device is mounted;

[0007] The lifting device is connected to the load device at one end and to a tilting device at the other end.

[0008] A flexible clamping device is connected to the flipping device, and the flexible clamping device is provided with a buffer device.

[0009] The control device is electrically connected to the conveying device, lifting device, tilting device, and flexible clamping device; wherein, the conveying device is used to convey the operating mechanism to be tilted to the load device, and the tilting device, flexible clamping device, and buffer device cooperate to clamp and tilt the operating mechanism to be tilted.

[0010] Furthermore, the conveying device includes a pallet and a rotary disc mounted on the pallet, the pallet being mounted on top of the load device;

[0011] The flexible clamping device includes a clamping block, a fixed seat, a fixed seat mounting plate, a first side plate, a cylinder mounting plate, a mounting bend plate, a tail flange, a second side plate, a first sliding bearing base, a rod end flange, a clamping cylinder, a piston rod, and a guide shaft. The fixed seat mounting plate is installed on both the first side plate and the second side plate. The fixed seat and the clamping block are installed on the fixed seat mounting plate. Three sets of clamping blocks are provided.

[0012] Furthermore, the first side plate is fixedly connected to the clamping cylinder via the mounting bend and the tail flange;

[0013] The clamping cylinder contains a piston rod, and the other end of the piston rod is fixed to the second side plate.

[0014] Furthermore, the guide shaft is disposed on the flipping device, and the first sliding bearing base is sleeved on the guide shaft. There are two first sliding bearing bases, one of which is connected to the first side plate, and the other is connected to the second side plate.

[0015] Furthermore, the tilting device includes a speed reducer, a first shaft, a first operating arm, a second operating arm, and rolling bearings. The speed reducer is equipped with a lifting device. The drive end of the speed reducer is connected to the first shaft. The first operating arm and the second operating arm are mounted on the first shaft.

[0016] Furthermore, the lifting device includes a bearing housing, a square tube, a sliding bearing base, a second shaft, a lifting piston rod, and a lifting cylinder. The lifting piston rod is disposed inside the lifting cylinder, and the end of the lifting piston rod is connected to the square tube. The bearing housing and the second shaft are mounted on the square tube, and the second shaft passes through the third sliding bearing base.

[0017] Furthermore, the buffer device includes a support plate protective pad, a support plate, a sliding arm, a first guide pin, a base, a second sliding bearing base, a buffer spring, a second guide pin, a washer, a nut, a spring, and a limiting sleeve;

[0018] The second sliding bearing base is fixed to the mounting plate of the clamping device. The buffer spring is sleeved on the second sliding bearing base, and the second guide pin passes through the second sliding bearing base.

[0019] Furthermore, one end of the second guide pin is fitted with a washer and a nut, the washer and the nut being used to limit the position of the buffer spring.

[0020] Furthermore, the other end of the second guide pin is fixed to the sliding arm, and the sliding arm is also fixed with a first guide pin. The other end of the first guide pin is provided with the spring and the limiting sleeve.

[0021] The guide pin and the base form a sliding pair, and the base is provided with the support plate, and the support plate is provided with a support plate protective pad.

[0022] Secondly, an automated high-voltage switch operating mechanism clamping and flipping method is provided, the method employing the clamping and flipping mechanism described above, comprising:

[0023] The operating mechanism to be flipped is placed on the conveying device so that the operating mechanism to be flipped is moved to the load device;

[0024] Using a control device, the flipping device, flexible clamping device, and buffer device work together to flip the operating mechanism to be flipped 180 degrees.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This flipping mechanism integrates a conveying device, a lifting device, a flipping device, and a flexible clamping device, realizing fully automated operation from conveying and clamping the operating mechanism to flipping, reducing manual intervention, improving production efficiency, and reducing the risk of errors or safety accidents caused by improper human operation.

[0027] In addition, the flexible clamping device, in conjunction with the buffer device, can provide appropriate pressure and cushioning when clamping the operating mechanism, avoiding damage to the mechanism, while also ensuring stability during the flipping process and reducing positioning deviations caused by vibration or impact.

[0028] 2. The clamping blocks are set in three sets, which can move freely laterally on the guide shaft under the action of the clamping piston to realize the clamping operation of the mechanism. There is no need to limit the mechanism, and there are no strict requirements on the initial position of the mechanism. At the same time, the initial spacing of the clamping blocks is large, which can clamp a variety of mechanisms of different sizes, making it widely applicable.

[0029] 3. The connection between the mounting plate and the tail flange provides a stable support point for the clamping cylinder, ensuring the stability of the clamping cylinder during operation and effectively preventing the clamping cylinder from shifting due to uneven force or vibration, thereby improving the accuracy and reliability of the clamping operation.

[0030] 4. The piston rod is directly connected to the clamping cylinder and the second side plate, realizing the direct transmission of force, reducing intermediate transmission links, making the clamping action faster and more sensitive, which helps to shorten the clamping time and improve production efficiency.

[0031] 5. The guide shaft provides stable guidance for the tilting device, ensuring smoothness and accuracy during the tilting process. The cooperation between the two first sliding bearing bases and the guide shaft limits lateral displacement of the tilting device during tilting, making the tilting action more stable and reliable. Furthermore, the first sliding bearing bases, as support points for the guide shaft, have strong load-bearing capacity.

[0032] 6. The lifting piston rod is located inside the lifting cylinder. The piston rod extends and retracts through the driving force of the cylinder, thereby driving the square tube to lift. This ensures the smoothness and controllability of the lifting process and avoids the impact caused by sudden start or stop.

[0033] 7. The buffer spring installed on the outer sleeve of the second sliding bearing base can absorb and disperse energy when subjected to impact or vibration, playing a role in buffering and shock absorption. This helps to protect the clamping device and operating mechanism from damage caused by instantaneous impact forces and extend the service life of the equipment.

[0034] 8. The use of washers and nuts can accurately position the buffer spring on the guide pin. By adjusting the tightness of the nut, it can be ensured that the buffer spring remains relatively stable when compressed or stretched, and will not shift or slip.

[0035] 9. The sliding pair formed by the guide pin and the base provides a stable guide and sliding path for the sliding arm. During the operation of the buffer device, the sliding arm can slide smoothly along the sliding pair formed by the guide pin and the base, ensuring the accuracy and stability of the buffer action.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0047] When assembling the high-voltage switch operating mechanism, it needs to be rotated 180 degrees and sealed with sealing strips. Currently, this process is primarily manual. The operating mechanism is hoisted using lifting equipment and then manually rotated. Due to the significant weight of the operating mechanism, manual rotation is very inconvenient, taking approximately ten minutes to rotate a single unit. Furthermore, manual operation presents technical challenges such as high risk and low efficiency.

[0048] In order to overcome the above-mentioned technical defects, the inventors have provided an automated high-voltage switch operating mechanism clamping and flipping device and method.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings:

[0050] As shown in Figures 1-3, an embodiment of the present invention provides an automated high-voltage switch operating mechanism clamping and flipping mechanism, comprising: a load device with a conveying device mounted thereon; a lifting device connected at one end to the load device and at the other end to a flipping device; a flexible clamping device connected to the flipping device, and a buffer device mounted on the flexible clamping device; and a control device electrically connected to the conveying device, the lifting device, the flipping device, and the flexible clamping device. The conveying device is used to convey the operating mechanism to be flipped to the load device, whereby the flipping device, the flexible clamping device, and the buffer device cooperate to clamp and flip the operating mechanism. This mechanism, by integrating the conveying device, the lifting device, the flipping device, and the flexible clamping device, achieves fully automated operation from conveying, clamping, to flipping the operating mechanism to be flipped. This significantly reduces manual intervention, improves production efficiency, and reduces the risk of errors or safety accidents caused by improper human operation. Meanwhile, the flexible clamping device, combined with a buffer device, provides appropriate pressure and cushioning when clamping the operating mechanism, preventing damage and ensuring stability during the flipping process, reducing positioning deviations caused by vibration or impact. Furthermore, automated operation reduces the impact of human factors on product quality, such as uneven operating force or inaccurate positioning. In addition, by precisely controlling the flipping angle and speed, the mechanism ensures the operating mechanism remains in optimal condition during flipping, thereby improving overall product quality and reliability. Increased production efficiency and improved product quality correspondingly reduce production and maintenance costs. This mechanism has a degree of versatility; by adjusting the control program or replacing some components, it can be adapted to different models or sizes of operating mechanisms. This flexibility and adaptability allow the mechanism to be widely used in the production and maintenance of various high-voltage switches. As shown in Figure 1, the conveying device includes a pallet 3 and a rotary disc 2 mounted on the pallet 3. The pallet 3 is mounted on the top of the load device. The flexible clamping device includes a clamping block 4, a fixed seat 5, a fixed seat mounting plate 6, a first side plate 7, a cylinder mounting plate 13, a mounting bend plate 14, a tail flange 15, a second side plate 16, a first sliding bearing base 17, a rod end flange 28, a clamping cylinder 27, a piston rod 31, and a guide shaft 32. The fixed seat mounting plate 6 is mounted on both the first side plate 7 and the second side plate 16. The fixed seat 5 and the clamping block 4 are mounted on the fixed seat mounting plate 6. Three sets of clamping blocks 4 are provided. In the above structure, the combination of pallet 3 and rotary disc 2 allows the operating mechanism to be flipped to be stably placed on pallet 3 and accurately positioned and transported by rotary disc 2. This ensures that the operating mechanism will not deviate or slip during transport, improving the accuracy and stability of transport. It also enables continuous and efficient transport of the operating mechanism to be flipped, reducing manual handling and waiting time, thereby improving overall production efficiency.The clamping module, consisting of three sets of clamping blocks 4, a fixed seat 5, a fixed seat mounting plate 6, a first side plate 7, a second side plate 16, a cylinder mounting plate 13, a rod end flange 28, a clamping cylinder 27, a fixed seat 5, a fixed seat mounting plate 6, clamping blocks 4, and a piston rod 31, achieves stable clamping of the mechanism to be flipped. This multi-point clamping method can evenly distribute the clamping force, avoiding localized damage to the operating mechanism. Furthermore, the cylinder mounting plate 13 and the mounting bend plate 14 allow the clamping device to flexibly adjust the clamping position and angle according to actual needs, improving operational flexibility and accuracy. The clamping cylinder 27 drives the clamping blocks 4 through the piston rod 31 to perform the clamping operation, achieving automated control, reducing manual intervention, and improving operational precision and efficiency. The cooperation between the guide shaft 32 and the rod end flange 28 not only provides stable guidance for the clamping operation but also plays a certain role in buffering and protection, reducing impact and vibration during the clamping process.

[0051] In this embodiment, the first side plate 7 is fixedly connected to the clamping cylinder 27 via the mounting bend plate 14 and the tail flange 15, providing a stable support point for the clamping cylinder 27. This ensures the stability of the clamping cylinder 27 during operation and effectively prevents displacement caused by uneven force or vibration, thereby improving the accuracy and reliability of the clamping operation. The mounting bend plate 14 and the tail flange 15 serve as connecting parts, making the connection between the clamping cylinder 27 and the first side plate 7 more flexible and adjustable. During equipment installation or debugging, the working position and clamping force of the clamping cylinder 27 can be optimized by adjusting the position and angle of these connecting parts, thus meeting the clamping requirements of different models or sizes of operating mechanisms. Since the clamping cylinder 27 is connected to the first side plate 7 via the mounting bend plate 14 and the tail flange 15, it can be easily disassembled and reinstalled when maintenance or replacement is required, reducing maintenance difficulty and cost.

[0052] In this embodiment, the clamping cylinder 27 contains a piston rod 31, the other end of which is fixed to the second side plate 16. The piston rod 31 directly connects the clamping cylinder 27 and the second side plate 16, realizing direct force transmission, reducing intermediate transmission links, and making the clamping action faster and more sensitive, which helps to shorten the clamping time and improve production efficiency. The direct connection between the piston rod 31 and the second side plate 16 makes the structure of the clamping device more compact, reducing unnecessary space occupation. Furthermore, the fixed connection between the piston rod 31 and the second side plate 16 usually adopts a simple threaded connection or pin connection, which is convenient for disassembly and replacement. When the clamping device needs maintenance or repair, the piston rod 31 and the second side plate 16 can be quickly disassembled, reducing maintenance difficulty and cost.

[0053] A guide shaft 32 is mounted on the tilting device. A limiting nut 33 is provided on one side of the guide shaft 32, and a first limiting pin 34 is installed on the limiting nut 33. A polyurethane pad 35 is installed on one side of the first limiting pin 34. A first sliding bearing base 17 is sleeved on the guide shaft 32. There are two first sliding bearing bases 17, one of which is connected to the first side plate 7, and the other is connected to the second side plate 16. The guide shaft 32 provides stable guidance for the tilting device, ensuring the smoothness and accuracy of the tilting process. Through the cooperation of the two first sliding bearing bases 17 and the guide shaft 32, the lateral displacement of the tilting device during the tilting process is limited, making the tilting action more stable and reliable. The first sliding bearing base 17, as the support point of the guide shaft 32, has a strong load-bearing capacity. The two first sliding bearing bases 17 are respectively connected to the first side plate 7 and the second side plate 16, distributing the load generated during the tilting process and improving the load-bearing capacity of the entire tilting device.

[0054] A sliding bearing or lubrication device is typically installed inside the first sliding bearing base 17 to reduce friction and wear between the guide shaft 32 and the first sliding bearing base 17, extending their service life and reducing equipment maintenance costs. Furthermore, the cooperation between the guide shaft 32 and the first sliding bearing base 17 allows for precise control of the tilting angle and speed, improving tilting accuracy and controllability, and helping to meet diverse production needs. Finally, the connection between the guide shaft 32 and the two first sliding bearing bases 17 forms a stable triangular structure, enhancing the structural rigidity of the tilting device and making it less prone to deformation or damage under heavy loads, thus improving the stability and durability of the equipment. As shown in Figure 1, the tilting device includes a reducer 24, a first shaft 37, a first operating arm 18, a second operating arm 36, and a rolling bearing 39. A mounting plate 40 is installed on one side of the rolling bearing 39, and a micro switch 41 is installed on one side of the mounting plate 40. The reducer 24 is equipped with a lifting device. The drive end of the reducer 24 is connected to the first shaft 37, on which the first operating arm 18 and the second operating arm 36 are mounted. The reducer 24 serves as a power source, providing a stable and adjustable driving force. Precise control of the tilting speed and torque can be achieved through the reducer 24, meeting the needs of different working conditions. The first shaft 37, as the main transmission component of the tilting device, connects the reducer 24 and the first operating arm 18 and the second operating arm 36, realizing power transmission. The first operating arm 18 and the second operating arm 36 are mounted on the first shaft 37 and can tilt as the first shaft 37 rotates, thereby achieving precise control of the tilted object and reducing friction and wear. The introduction of rolling bearing 39 effectively reduces friction and wear during the flipping process. Rolling bearing 39 can withstand large radial and axial loads while maintaining a low coefficient of friction, thus extending the service life of the flipping device. A first spring 25 is installed on the second limiting pin 26, and the rod end flange 28 is mounted on the clamping cylinder 27. Rolling bearing 39 also has good self-rotation performance, which helps reduce energy loss during the flipping process and improves flipping efficiency. Through the coordinated action of reducer 24, first shaft 37, first operating arm 18, and second operating arm 36, the flipping device can efficiently complete the object flipping operation, improving work efficiency. At the same time, because the movement trajectory and force conditions of each component are precisely controlled during the flipping process, operational safety is improved, and the possibility of accidents is reduced.

[0055] In this embodiment, the lifting device includes a bearing housing 38, a square tube 42, a third sliding bearing base 43, a second shaft 44, a lifting piston rod 46, and a lifting cylinder 47. The lifting piston rod 46 is disposed within the lifting cylinder 47, and its end is connected to the square tube 42. The bearing housing 38 and the second shaft 44 are mounted on the square tube 42, with the second shaft 44 passing through the third sliding bearing base 43. The lifting cylinder 47 serves as a power source, transmitting lifting force through the lifting piston rod 46, providing continuous and controllable lifting force to ensure a smooth lifting process. The direct connection between the lifting piston rod 46 and the square tube 42 reduces losses during force transmission and improves lifting efficiency. The square tube 42, as the main supporting structure of the lifting device, possesses sufficient strength and rigidity to withstand various forces and torques during the lifting process. The installation of bearing housing 38 and second shaft 44 provides stable support and guidance for square tube 42, ensuring stability and accuracy during the lifting process. The second shaft 44 passes through the third sliding bearing base 43, reducing friction and wear and improving the durability of the lifting device.

[0056] In this embodiment, the buffer device includes a support plate protective pad 8, a support plate 9, a sliding arm 10, a first guide pin 11, a base 12, a second sliding bearing base 19, a buffer spring 20, a second guide pin 21, a washer 22, a nut 23, a second spring 29, and a limiting sleeve 30. The second sliding bearing base 19 is fixed to the mounting plate 6 of the clamping device. The buffer spring 20 is sleeved on the second sliding bearing base 19, and the second guide pin 21 passes through the second sliding bearing base 19. The buffer spring 20, sleeved on the second sliding bearing base 19, can absorb and disperse this energy when subjected to external impact or vibration, thereby playing an effective buffering role. This helps protect the clamping device and the clamped mechanism to be flipped from damage and extends the service life of the equipment. The second guide pin 21, passing through the second sliding bearing base 19, provides a stable guide for the sliding arm 10, ensuring the stability and accuracy of the sliding arm 10 during movement and preventing errors caused by offset or shaking. Meanwhile, the second sliding bearing base 19 serves as a support point, providing stable support for the entire buffer device and enhancing its rigidity and stability. The combined use of the nut 23 and washer 22 allows the preload of the buffer spring 20 to be easily adjusted, thereby adjusting the buffering effect of the buffer device according to actual needs and improving the flexibility and adaptability of the device.

[0057] The second guide pin 21 is fitted with a washer 22 and a nut 23 at one end. The washer 22 and nut 23 are used to limit the position of the buffer spring 20. The cooperation of the washer 22 and nut 23 allows for precise control of the compression and extension of the buffer spring 20. By adjusting the tightness of the nut 23, the preload of the buffer spring 20 can be changed, thereby achieving precise adjustment of the buffering effect. This helps ensure that the buffer device can buffer in a predetermined manner when subjected to impact or vibration, improving the stability and reliability of the device. The cooperation of the washer 22 and nut 23 effectively prevents the buffer spring 20 from falling off or shifting from the second guide pin 21 during vibration or impact, ensuring that the buffer spring 20 always remains in the correct position, thus ensuring the normal operation of the buffer device. The nut 23, fastened to the second guide pin 21, together with the washer 22, forms a stable connection structure, enhancing the rigidity and stability of the buffer device, enabling it to better withstand external impacts and vibrations. Simultaneously, it also helps reduce noise and wear caused by vibration or impact, extending the service life of the device. The design of washer 22 and nut 23 makes the installation and replacement of buffer spring 20 more convenient. During installation, simply put buffer spring 20 onto the second guide pin 21 and then secure it with washer 22 and nut 23. During maintenance, if buffer spring 20 needs to be replaced or adjusted, it can also be easily achieved by removing nut 23 and washer 22.

[0058] In this embodiment, the other end of the second guide pin 21 is fixed to the sliding arm 10, and the sliding arm 10 is also fixed with a first guide pin 11. The other end of the first guide pin 11 is provided with a second spring 29 and a limiting sleeve 30. The first guide pin 11 and the base 12 form a sliding pair, and a support plate 9 is provided on the base 12, with a support plate protective pad 8 on the support plate 9. The sliding pair formed by the first guide pin 11 and the base 12 provides a stable guide and sliding path for the sliding arm 10, ensuring that the sliding arm 10 can slide smoothly along a predetermined trajectory when subjected to external forces, without deviation or shaking. The second spring 29 and the limiting sleeve 30 provide buffering and limiting functions for the sliding arm 10. When the sliding arm 10 is subjected to impact or vibration, the second spring 29 can absorb and disperse this energy, thereby reducing the impact on other parts of the device. At the same time, the limiting sleeve 30 restricts the range of movement of the sliding arm 10, preventing excessive movement that could lead to damage or safety accidents. The support plate 9 and the support plate protective pad 8 provide additional support and protection for the clamping device or workpiece. The support plate 9 can withstand part of the weight and force, while the support plate protective pad 8 can prevent direct contact with the support plate 9, thereby avoiding scratches or damage.

[0059] In this embodiment, the load device includes a load support frame 1 and a gantry frame 45. The gantry frame 45 is disposed on the top of the load support frame 1, and the tray 3 is disposed on the top of the gantry frame 45.

[0060] Secondly, an automated high-voltage switch operating mechanism clamping and flipping method is provided. The method employs the clamping and flipping mechanism described above, as shown in Figure 4, and includes:

[0061] S101. Place the operating mechanism to be flipped on the conveying device to move it onto the load device. For example, the entire clamping and flipping mechanism is controlled by a PLC controller. Magnetic rings are present in the clamping cylinder 27 and lifting cylinder 47. When the clamping cylinder 27 retracts or extends, the magnetic rings send a feedback signal back to the PLC controller. After a few seconds, the PLC controller sends a signal for the next action. Simultaneously, the mounting plate 40 and microswitch 41 are used to cut off the power supply to the reducer 24 circuit and the control circuit signal when the flipping mechanism is in position. The specific operating principle is as follows: Before operation, the clamping and flipping mechanism is in its initial position, with the square tube 42 and its first and second operating arms 18 and 37 in a raised state. When clamping is required, the operating mechanism to be flipped is placed on the rotary disc 2 of the conveying device and transported along with the entire conveying device to the load support frame 1 of the load device via a conveyor belt. At this time, pressing the remote control button sends a clamping and flipping command.

[0062] S102. Using the control device, the flipping device, flexible clamping device, and buffer device work together to flip the operating mechanism to be flipped 180 degrees. For example, after the PLC controller receives the instruction, the circuit of the geared motor 24 is turned on, the geared motor 24 rotates, driving the flipping device, clamping device, buffer device, and the clamped operating mechanism to rotate and flip 180 degrees around the first axis 37, to above the load support frame 1. At this time, the micro switch 41 switches, the circuit of the geared motor 41 is de-energized, and the PLC controller issues a descent instruction.

[0063] Upon receiving the command, the PLC controller activates the solenoid valve, controlling the lifting cylinder 47 and lifting piston rod 46 of the lifting device to retract, causing all other devices except the load device and conveying device to descend. Once the device reaches the preset position, the magnetic ring inside the lifting cylinder 47 sends a descent completion signal to the PLC controller. Several seconds later, the PLC controller issues a clamping command. Upon receiving the clamping command, the clamping and tilting mechanism activates the solenoid valve, controlling the clamping cylinder 27 and piston rod 31 to retract. When the device retracts to the preset position (at which point the clamping action is complete), the magnetic ring inside the clamping cylinder 27 sends a clamping completion signal to the PLC controller. Several seconds later, the PLC controller issues a tilting command. Upon receiving the clamping command, the circuit of the geared motor 24 is activated, and the geared motor 24 rotates, causing the tilting device, clamping device, buffer device, and the tilting operating mechanism to rotate around the first axis 37. When the device has tilted 180 degrees to the desired position, the second operating arm 36 presses the micro switch 41 to switch it, at which point the power to the geared motor 24 circuit is disconnected, and a release command is sent to the PLC controller. A few seconds later, after receiving the instruction, the PLC controller activates the solenoid valve to release the clamping cylinder 27 and piston rod 31 of the clamping device and disconnects the control signal. At this time, the buffer device provides cushioning and support for the clamping and flipping mechanism, while the flipping device returns to its initial position. The flipping operation is now complete, and the sealing strip can be manually applied. After application, the operating mechanism can be manually moved to the storage area, and the device can be controlled again to complete the sealing strip application for the next machine.
