Description

Technical Field

[0001] This utility model relates to the field of refrigerator recycling technology, and in particular to a refrigerator handling device. Background Technology

[0002] With the continuous expansion of the global home appliance consumer market, the number of discarded refrigerators is also increasing. Effective recycling of discarded refrigerators is not only crucial for resource reuse but also an important requirement for environmental protection. In the recycling process, transporting the refrigerators to the assembly line is a critical preliminary step before subsequent dismantling. Traditional handling of discarded refrigerators relies mainly on manual labor, a method with serious drawbacks. Firstly, discarded refrigerators are large and heavy, typically weighing tens to hundreds of kilograms each. Their irregular shapes also make manual handling extremely physically demanding, leading to high labor intensity for workers. Long-term engagement in this type of work can easily result in occupational diseases such as lumbar muscle strain and joint injuries. Secondly, manual handling is extremely inefficient. In recycling plants, the number of discarded refrigerators to be processed is often large, and the speed of manual handling is far from meeting the pace of large-scale industrial recycling, severely restricting overall production efficiency and increasing recycling costs.

[0003] To address the challenges of manual handling, some companies have introduced auxiliary equipment. However, this equipment lacks flexibility during handling; for example, when moving used refrigerators onto the assembly line, it cannot flexibly adjust the refrigerator's orientation, affecting subsequent dismantling processes.

[0004] Therefore, it is necessary to improve the existing handling process for used refrigerators in order to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a refrigerator handling device that can efficiently and safely handle used refrigerators and flexibly adjust the angle of used refrigerators, thereby improving the automation level and work efficiency of used refrigerator recycling and processing, while reducing the labor intensity of operators.

[0006] A refrigerator handling device, comprising:

[0007] A support frame is provided with a movable output free end, a suction mechanism is provided on the output free end, and a suction head is provided on the suction mechanism;

[0008] A flipping mechanism is provided between the suction mechanism and the output free end. The flipping mechanism is provided with a flipping output end, which is connected to the suction mechanism and can drive the suction mechanism to move so as to change the position of the suction head.

[0009] A flipping mechanism is installed between the suction mechanism and the output free end. The flipping mechanism can be a drive system consisting of a rotary motor and a reducer. The output shaft of the rotary motor is connected to the input shaft of the reducer, and the output shaft of the reducer serves as the flipping output end, which is fixedly connected to the suction mechanism. When the rotary motor starts, the reducer's deceleration action allows the flipping output end to rotate slowly and steadily, thereby driving the suction mechanism to flip around the output shaft, changing the position and angle of the suction head.

[0010] In practical applications, when it's necessary to move used refrigerators, the drive motor first moves the free end of the suction mechanism on the support, positioning it above the refrigerator at a suitable position. Then, the vacuum pump is activated, causing the suction head to adhere to the refrigerator's surface. Next, depending on the refrigerator's recycling needs, if the refrigerator's angle needs adjustment, a rotary motor is activated, driving the suction mechanism to rotate and adjust the refrigerator to the appropriate angle. Finally, the drive motor again moves the free end of the suction mechanism, carrying the refrigerator, to the designated location on the production line. The vacuum pump is then turned off, the refrigerator is released, and one handling operation is complete.

[0011] The device's flipping mechanism drives the suction mechanism to flip, changing the position and angle of the suction head. This allows for flexible angle adjustment of the used refrigerators to meet specific recycling requirements. This flexible angle adjustment function enables it to adapt to various types of used refrigerators, improving the device's versatility and applicability.

[0012] Furthermore, this device can greatly reduce the labor intensity of handling refrigerators, and reduce the risk of fatigue and injury to operators due to long hours and high-intensity work.

[0013] In a preferred embodiment of this invention, the suction mechanism includes a suction frame and a suction head. The suction head is fixed to one side of the suction frame, and one side of the suction frame is hinged to the output free end.

[0014] In a preferred embodiment of this invention, the suction head includes a suction cup body, the suction cup body is provided with an air extraction hole, the air extraction hole is connected to an external air extraction device, and a rubber ring is provided on the edge of the suction cup body.

[0015] The suction rack and the output free end are hinged, allowing the suction rack to rotate around the hinge point. This design enables the device to flexibly adjust the refrigerator's angle during transport. When moving the refrigerator onto the assembly line, it can be adjusted to a suitable angle according to the requirements of subsequent disassembly or processing steps, facilitating operator work and improving efficiency.

[0016] The rubber ring on the edge of the suction cup has excellent sealing performance. During the process of creating negative pressure through suction, the rubber ring can tightly adhere to the refrigerator surface, preventing air leakage and ensuring that sufficient negative pressure can be formed inside the suction cup, thus firmly adhering to the refrigerator. Even if there are some unevenness on the refrigerator surface, the rubber ring can compensate for the seal through its own elastic deformation, further enhancing the stability of the adsorption.

[0017] In a preferred embodiment of this utility model, the suction holder is provided with a plurality of operating handles, wherein at least one of the operating handles is installed on the side of the suction holder away from the suction cup, and at least one of the operating handles is installed on the side of the suction holder away from the side connected to the suction cup.

[0018] Each of the operating handles is equipped with multiple operating buttons, and the operating handles are electrically connected to the air extraction device and the flipping mechanism.

[0019] In this embodiment, several operating handles are reasonably arranged on the suction rack. A main operating handle is installed on the side of the suction rack away from the suction cup, making it convenient for the operator to perform the main operations while standing directly in front of the refrigerator. At the same time, an auxiliary operating handle is installed on the side of the suction rack away from the contact with the suction cup (side view), which is convenient for use when it is necessary to adjust the refrigerator's posture from the side.

[0020] Each operating handle is equipped with multiple operating buttons. In practical applications, these buttons may include suction buttons, release buttons, rise buttons, fall buttons, flip start buttons, and flip stop buttons. The operating handle integrates a complex and stable circuit system, which is electrically connected to the vacuum equipment and flipping mechanism via shielded cables, ensuring the accuracy and stability of signal transmission.

[0021] In a preferred embodiment of this utility model, the support includes a column, a lifting structure, upper and lower swing arms, and left and right swing arms. The column is vertically arranged on a horizontal plane, and the lifting structure is arranged on the top of the column. The lifting structure includes a first cylinder and a mounting base. The first cylinder is fixed on the top of the column, and the mounting base is arranged at the output end of the first cylinder.

[0022] The upper and lower swing arms have a first end and a second end that are arranged opposite to each other. The first end of the upper and lower swing arms is hinged to the mounting base, and the second end of the upper and lower swing arms is hinged to one end of the left and right swing arms. The left and right swing arms have an output free end at the end away from the upper and lower swing arms.

[0023] The hinged design of the upper and lower swing arms and the left and right swing arms allows for flexible positioning in three-dimensional space. The upper and lower swing arms can rotate in the vertical plane, while the left and right swing arms can rotate in the horizontal plane. Their coordinated movement enables the suction mechanism at the output free end to precisely reach any position on the refrigerator. In actual operation, regardless of the refrigerator's placement in the workshop, the rotation of the swing arms can accurately move the suction mechanism above the refrigerator for suction operation, greatly improving the accuracy and efficiency of handling.

[0024] In a preferred embodiment of this utility model, the mounting base includes a base and a support plate, the base is fixed to the output end of the first cylinder, and the support plate is vertically arranged on the base;

[0025] Two support plates are provided, and the two support plates are parallel to each other; the first end of the upper and lower swing arms is hinged to the support plates;

[0026] A second cylinder is provided on the base, the axis of the piston rod of the second cylinder is perpendicular to the surface of the base, and the piston rod of the second cylinder is hinged to the first end of the upper and lower swing arms.

[0027] The first cylinder allows the mounting base to drive the upper and lower swing arms to achieve a wide range of height adjustments. When dealing with refrigerators of different heights, it can quickly and accurately adjust the suction mechanism to the appropriate height position, ensuring smooth suction operation and improving the device's adaptability to different refrigerators.

[0028] The piston rod of the second cylinder is hinged to the first end of the upper and lower swing arms. By controlling the extension and retraction of the second cylinder, the rotation angle of the upper and lower swing arms can be precisely adjusted. This allows the suction mechanism to not only adjust the height but also finely adjust the angle to better fit the refrigerator surface, enhance the adsorption effect, and ensure the stability of the refrigerator during transportation.

[0029] This application, through the coordinated operation of the first and second cylinders, endows the device with greater operational flexibility in the vertical direction. Operators can control the actions of the two cylinders individually or simultaneously, depending on the actual situation, to achieve diverse adjustments to the position and angle of the suction mechanism. Compared to a single height or angle adjustment method, this dual-cylinder coordinated design significantly improves the device's operational flexibility in complex working scenarios, enabling more efficient completion of refrigerator handling tasks.

[0030] In a preferred embodiment of this invention, an auxiliary swing arm is provided on one side of the upper and lower swing arms. One end of the auxiliary swing arm is fixedly connected to the second end of the upper and lower swing arms, and the other end is hinged to the support plate.

[0031] The auxiliary swing arm supports and assists the rotation of the upper and lower swing arms. When the upper and lower swing arms rotate upward, the auxiliary swing arm provides upward support; when the upper and lower swing arms rotate downward, the auxiliary swing arm stabilizes their movement trajectory, ensuring that the suction mechanism accurately approaches the refrigerator and performs the suction operation. After the refrigerator is suctioned, the refrigerator is transported to the designated position on the assembly line through the coordinated movement of the first cylinder and the swing arm.

[0032] When handling heavy refrigerators, the auxiliary swing arm can share some of the weight, making the entire swing arm system more stable, reducing the risk of the refrigerator falling during transport, and ensuring operational safety.

[0033] In a preferred embodiment of this invention, braking devices are provided at the output free end, the connection between the upper and lower swing arms and the left and right swing arms, and the output end of the first cylinder.

[0034] This application incorporates multiple braking devices, enabling precise positioning of several key components of the device. During transport, whether adjusting the height, angle, or horizontal position of the suction mechanism, the braking devices can precisely control the state of each component, allowing the entire device to operate along a predetermined trajectory and position, thus improving overall positioning accuracy.

[0035] Specifically, the braking device in this application may be a disc brake.

[0036] In a preferred embodiment of this invention, the flipping mechanism includes a linear drive device, which is fixed to the output free end and has an output end that is fixedly connected to one side of the suction rack.

[0037] The linear drive device can be an electric actuator, which features rapid response. The operator simply presses a control button, and the electric actuator activates, driving the suction rack and the refrigerator to flip. Compared to some traditional flipping methods, such as manual flipping or complex mechanical transmission flipping, this significantly reduces the flipping operation time and improves work efficiency. Furthermore, the electric actuator can achieve continuous linear motion and can extend and retract multiple times as needed, thus easily achieving multiple flips or flips at different angles.

[0038] In a preferred embodiment of this invention, a pressure display is also included, which is connected to the suction cup.

[0039] The pressure indicator displays the pressure of the suction cup, allowing operators to visually determine whether the suction cup is strong enough to lift the refrigerator, thus avoiding the risk of the refrigerator falling due to insufficient suction.

[0040] The beneficial effects of this utility model are as follows:

[0041] This utility model provides a refrigerator handling device, which includes a support frame with a movable output free end. A suction mechanism with a suction head is mounted on the output free end. A flipping mechanism is connected between the suction mechanism and the output free end, and this mechanism has a flipping output end connected to the suction mechanism. The flipping output end can drive the suction mechanism to move, thereby changing the position of the suction head. In use, when a used refrigerator needs to be handled, the output free end is first moved on the support frame to move the suction mechanism to a suitable position above the used refrigerator. Then, the suction head adheres to the surface of the refrigerator. Next, if the refrigerator's angle needs to be adjusted according to the recycling requirements, the flipping mechanism is activated, driving the suction mechanism to flip and adjust the refrigerator to the appropriate angle. Finally, the output free end is moved again to move the suction mechanism with the refrigerator attached to it to the designated assembly line position. The vacuum pump is then turned off, the refrigerator is released, and one handling operation is completed. The movable output free end of this device can move flexibly on the support frame, allowing the suction mechanism to quickly and accurately reach the top of the used refrigerator, reducing adjustment time and improving the initial handling efficiency. The flipping mechanism drives the suction mechanism to flip, changing the position and angle of the suction head. This allows for flexible angle adjustments to the used refrigerators according to specific recycling requirements, making the device adaptable to handling various types of used refrigerators and improving its versatility and applicability. The device also reduces manual handling of used refrigerators, increasing the automation level of the recycling process. Attached Figure Description

[0049] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0050] The traditional process of moving used refrigerators to the assembly line relies primarily on manual labor, a method with serious drawbacks. Firstly, used refrigerators are large and heavy, typically weighing tens to hundreds of kilograms each. Their irregular shapes further complicate manual handling, requiring significant physical exertion and resulting in extremely high labor intensity for workers. Prolonged exposure to this type of work can easily lead to occupational diseases such as lumbar muscle strain and joint injuries. Secondly, manual handling is extremely inefficient. In recycling plants, the number of used refrigerators awaiting processing is often large, and the speed of manual handling is far from meeting the pace of large-scale industrial recycling. This severely restricts overall production efficiency and increases recycling costs.

[0051] To address the challenges of manual handling, some companies have introduced auxiliary equipment. However, this equipment lacks flexibility during handling; for example, when moving used refrigerators onto the assembly line, it cannot flexibly adjust the refrigerator's orientation, affecting subsequent dismantling processes.

[0052] Based on this, this application provides a refrigerator handling device.

[0053] Example 1

[0054] like Figures 1-5 As shown, this embodiment provides a refrigerator handling device, comprising:

[0055] A bracket 1 is provided with a movable output free end 14, a suction mechanism 3 is provided on the output free end 14, and a suction head 32 is provided on the suction mechanism 3.

[0056] A flipping mechanism 2 is provided between the suction mechanism 3 and the output free end 14. The flipping mechanism 2 is provided with a flipping output end, which is connected to the suction mechanism 3. The flipping output end can drive the suction mechanism 3 to move, thereby changing the position of the suction head 32.

[0057] A flipping mechanism 2 is provided between the suction mechanism 3 and the output free end 14. The flipping mechanism 2 can be a drive system consisting of a rotary motor and a reducer. The output shaft of the rotary motor is connected to the input shaft of the reducer, and the output shaft of the reducer serves as the flipping output end, which is fixedly connected to the suction mechanism 3. When the rotary motor starts, the reducer slows down the flipping output end, causing it to rotate slowly and steadily, thereby driving the suction mechanism 3 to flip around the output shaft and changing the position and angle of the suction head 32.

[0058] In practical applications, when it is necessary to move discarded refrigerators, the drive motor first controls the output free end 14 to move on the support 1, moving the suction mechanism 3 to a suitable position above the discarded refrigerator. Then, the vacuum pump is started, causing the suction head 32 to adhere to the surface of the refrigerator. Next, depending on the needs of refrigerator recycling, if the angle of the refrigerator needs to be adjusted, the rotary motor is started, driving the suction mechanism 3 to rotate via the flipping mechanism 2, adjusting the refrigerator to the appropriate angle. Finally, the drive motor again controls the output free end 14 to move, transporting the suction mechanism 3 with the refrigerator attached to it to the designated assembly line position, the vacuum pump is turned off, the refrigerator is released, and one handling operation is completed.

[0059] The device's flipping mechanism 2 drives the suction mechanism 3 to flip, changing the position and angle of the suction head 32. This allows for flexible angle adjustment of the used refrigerators according to specific recycling requirements. This flexible angle adjustment function enables it to adapt to various types of used refrigerators, improving the device's versatility and applicability.

[0060] Furthermore, this device can greatly reduce the labor intensity of handling refrigerators, and reduce the risk of fatigue and injury to operators due to long hours and high-intensity work.

[0061] Example 2

[0062] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0063] In this embodiment, the suction mechanism 3 includes a suction frame 31 and a suction head 32. The suction head 32 is fixed to one side of the suction frame 31, and one side of the suction frame 31 is hinged to the output free end 14.

[0064] In this embodiment, the suction head 32 includes a suction cup body 321, which has an air extraction hole 322 connected to an external air extraction device. A rubber ring 323 is provided on the edge of the suction cup body 321. The air extraction device can be a negative pressure pump.

[0065] The suction rack 31 is hinged to the output free end 14, allowing the suction rack 31 to rotate around the hinge point. This design enables the device to flexibly adjust the angle of the refrigerator during handling. When transporting the refrigerator to the assembly line, it can be adjusted to a suitable angle according to the requirements of subsequent disassembly or processing steps, facilitating operation and improving work efficiency.

[0066] The rubber ring 323 on the edge of the suction cup 32 and suction cup body 321 has good sealing performance. During the process of creating negative pressure through suction, the rubber ring 323 can tightly adhere to the surface of the refrigerator to prevent air leakage and ensure that sufficient negative pressure can be formed inside the suction cup 32, thereby firmly adhering to the refrigerator. Even if there is some unevenness on the surface of the refrigerator, the rubber ring 323 can compensate for the seal through its own elastic deformation, further enhancing the stability of the adsorption.

[0067] More preferably, the device also includes a pressure display connected to the suction cup 32.

[0068] The pressure indicator is used to display the pressure of the suction cup 32, so that the operator can intuitively judge whether the suction of the suction cup 32 is sufficient to lift the refrigerator, thus avoiding the risk of the refrigerator falling due to insufficient suction.

[0069] During operation, as the suction device pumps air, a negative pressure gradually forms inside the suction cup 32. At this time, the pressure display shows the pressure value inside the suction cup 32 in real time. The operator observes the pressure display; when the pressure reaches the preset range sufficient to safely lift the refrigerator, it indicates that the suction force of the suction cup 32 is sufficient for handling. The operator controls the swing arms and cylinders to move the suction mechanism 3, which is holding the refrigerator, to the designated position on the production line. Upon arrival, the pumping stops, the pressure inside the suction cup 32 returns to normal, and the refrigerator is released.

[0070] Example 3

[0071] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 2.

[0072] In this embodiment, the suction holder 31 is provided with a plurality of operating handles 33, wherein at least one of the operating handles 33 is installed on the side of the suction holder 31 away from the suction cup 32, and at least one of the operating handles 33 is installed on the side of the suction holder 31 away from the side connected to the suction cup 32;

[0073] Each of the operating handles 33 is provided with multiple operating buttons 331, and the operating handles 33 are electrically connected to the air extraction device and the flipping mechanism 2.

[0074] In this embodiment, several operating handles 33 are reasonably arranged on the suction rack 31. A main operating handle 33 is installed on the side of the suction rack 31 away from the suction cup 32, making it convenient for the operator to perform the main operation while standing directly in front of the refrigerator. At the same time, an auxiliary operating handle 33 is installed on the side of the suction rack 31 away from the suction cup 32 (side view), which is convenient for use when it is necessary to adjust the refrigerator's posture from the side.

[0075] Each operating handle 33 is equipped with multiple operating buttons 331. In practical applications, these buttons may include suction buttons, release buttons, rise buttons, fall buttons, flip start buttons, flip stop buttons, etc. The operating handle 33 integrates a complex and stable circuit system, which is electrically connected to the air extraction equipment and the flipping mechanism 2 through shielded cables to ensure the accuracy and stability of signal transmission.

[0076] Example 4

[0077] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0078] In this embodiment, the support 1 includes a column 11, a lifting structure 5, upper and lower swing arms 12, and left and right swing arms 13. The column 11 is vertically arranged on a horizontal plane, and the lifting structure 5 is arranged on the top of the column 11. The lifting structure 5 includes a first cylinder 51 and a mounting base 52. The first cylinder 51 is fixed on the top of the column 11, and the mounting base 52 is arranged at the output end of the first cylinder 51.

[0079] The upper and lower swing arms 12 have a first end and a second end that are arranged opposite to each other. The first end of the upper and lower swing arms 12 is hinged to the mounting base 52, and the second end of the upper and lower swing arms 12 is hinged to one end of the left and right swing arms 13. The left and right swing arms 13 are provided with an output free end 14 at the end away from the upper and lower swing arms 12.

[0080] The column 11 of this application can be made of high-strength carbon steel and has a square or round column structure. It can be installed vertically and firmly on the cement floor of the workshop by anchor bolts to ensure that the entire device has a solid supporting foundation.

[0081] The upper and lower swing arms 12 are made of aluminum alloy, a material that is lightweight yet strong enough to meet usage requirements. The first end of the upper and lower swing arms 12 is hinged to the mounting base 52 via a pin, allowing the upper and lower swing arms 12 to rotate flexibly in the vertical plane around this hinge point. The second end of the upper and lower swing arms 12 is also hinged to one end of the left and right swing arms 13 via a pin. The left and right swing arms 13 are also made of aluminum alloy, with the output free end 14 mounted at the end furthest from the upper and lower swing arms 12.

[0082] The hinged design of the upper and lower swing arms 12 and the left and right swing arms 13 allows the device to be flexibly positioned in three-dimensional space. The upper and lower swing arms 12 can rotate in the vertical plane, and the left and right swing arms 13 can rotate in the horizontal plane. Together, they enable the suction mechanism 3 on the output free end 14 to precisely reach any position on the refrigerator. In actual operation, regardless of the refrigerator's placement in the workshop, the suction mechanism 3 can be accurately moved above the refrigerator for suction operation by rotating the swing arms, greatly improving the accuracy and efficiency of handling.

[0083] In this embodiment, the mounting base 52 includes a base 522 and a support plate 521. The base 522 is fixed to the output end of the first cylinder 51, and the support plate 521 is vertically arranged on the base 522.

[0084] Two support plates 521 are provided, and the two support plates 521 are parallel to each other; the first end of the upper and lower swing arms 12 is hinged to the support plates 521.

[0085] A second cylinder 6 is provided on the base 522. The axis of the piston rod of the second cylinder 6 is perpendicular to the surface of the base 522. The piston rod of the second cylinder 6 is hinged to the first end of the upper and lower swing arms 12.

[0086] The first cylinder 51 enables the mounting base 52 to drive the upper and lower swing arms 12 to achieve a wide range of height adjustments. When dealing with refrigerators of different heights, it can quickly and accurately adjust the suction mechanism 3 to the appropriate height position, ensuring the smooth operation of the suction process and improving the adaptability of the device to different refrigerators.

[0087] The piston rod of the second cylinder 6 is hinged to the first end of the upper and lower swing arms 12. By controlling the extension and retraction of the second cylinder 6, the rotation angle of the upper and lower swing arms 12 can be precisely adjusted. This allows the suction mechanism 3 to not only adjust the height but also finely adjust the angle to better fit the surface of the refrigerator, enhance the adsorption effect, and ensure the stability of the refrigerator during transportation.

[0088] This application, through the coordinated operation of the first cylinder 51 and the second cylinder 6, endows the device with greater operational flexibility in the vertical direction. Operators can control the actions of the two cylinders individually or simultaneously, depending on the actual situation, to achieve diverse adjustments to the position and angle of the suction mechanism 3. Compared to a single height or angle adjustment method, this dual-cylinder coordinated design greatly improves the device's operational flexibility in complex working scenarios, enabling more efficient completion of refrigerator handling tasks.

[0089] Example 5

[0090] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0091] In this embodiment, an auxiliary swing arm 15 is provided on one side of the upper and lower swing arms 12. One end of the auxiliary swing arm 15 is fixedly connected to the second end of the upper and lower swing arms 12, and the other end is hinged to the support plate 521.

[0092] In practical applications, the auxiliary swing arm 15 is made of the same material as the upper and lower swing arms 12. One end of the auxiliary swing arm 15 is fixedly connected to the second end of the upper and lower swing arms 12 by a connecting plate bolt, and the other end is hinged to the support plate 521 by a pin.

[0093] The auxiliary swing arm 15 supports and assists the rotation of the upper and lower swing arms 12. When the upper and lower swing arms 12 rotate upward, the auxiliary swing arm 15 provides upward support; when the upper and lower swing arms 12 rotate downward, the auxiliary swing arm 15 also stabilizes its movement trajectory, ensuring that the suction mechanism 3 accurately approaches the refrigerator and performs the suction operation. After suctioning the refrigerator, the refrigerator is transported to the designated position on the assembly line through the coordinated movement of the first cylinder 51 and the swing arm.

[0094] When adsorbing a heavy refrigerator, the auxiliary swing arm 15 can share some of the weight, making the entire swing arm system more stable, reducing the risk of the refrigerator falling during transportation, and ensuring operational safety.

[0095] Example 6

[0096] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0097] In this embodiment, braking devices 4 are provided at the output free end 14, the connection between the upper and lower swing arms 12 and the left and right swing arms 13, and the output end of the first cylinder 51.

[0098] This application incorporates multiple braking devices 4, enabling the positioning of several key components of the device. During transport, whether adjusting the height, angle, or horizontal position of the suction mechanism 3, the braking device 4 can precisely control the state of each component, allowing the entire device to operate according to a predetermined trajectory and position, thus improving overall positioning accuracy.

[0099] Specifically, the braking device 4 in this application can be a disc brake.

[0100] In one specific implementation, when a used refrigerator needs to be moved, the first cylinder 51 is activated, causing the mounting base 52 to rise or fall. Through the coordinated movement of the upper and lower swing arms 12 and the left and right swing arms 13, the suction mechanism 3 at the output free end 14 is moved to a suitable position above the refrigerator. During the movement, the braking device 4 is released, ensuring that the swing arms can rotate and move freely. When the suction mechanism 3 reaches the target position, the operator activates the braking device 4 via a button on the handle, braking the output free end 14, the connection between the upper and lower swing arms 12 and the left and right swing arms 13, and the output end of the first cylinder 51, fixing each component in its current position. Then, the suction mechanism 3 picks up the refrigerator, and the braking device 4 is released again. Through the coordinated movement of each component, the refrigerator is moved to the designated position on the assembly line. Upon arrival, the braking device 4 is activated again to fix the position, and finally, the suction mechanism 3 releases the refrigerator.

[0101] Example 7

[0102] like Figures 1-5 As shown, this embodiment is an improvement on embodiment 1.

[0103] In this embodiment, the flipping mechanism 2 includes a linear drive device, which is fixed to the output free end 14. The linear drive device has an output end, which is fixedly connected to one side of the suction rack 31.

[0104] The linear drive device can be a cylinder or an electric actuator. Specifically, the flipping output end can be the actuator rod of the electric actuator.

[0105] The electric push rod features a rapid response capability. The operator simply presses a control button to activate the electric push rod, causing the suction rack 31 and the refrigerator being suctioned to flip. Compared to some traditional flipping methods, such as manual flipping or complex mechanical transmission flipping, this significantly reduces the flipping operation time and improves work efficiency. Furthermore, the electric push rod can achieve continuous linear motion and can extend and retract multiple times as needed, thus conveniently enabling multiple flips or flips at different angles of the refrigerator.

[0106] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0107] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0108] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
