[0024] Please see Figure 1 This utility model provides a robotic gripper 100 for flipping various types of refrigerator liners. This robotic gripper 100 can handle mixed production and flipping of different types of refrigerator liners in a flexible production line; it can recognize and automatically adjust the width during mixed production, thus achieving mixed production and flipping of different types of refrigerator liners.

[0025] like Figure 1 and Figure 2 As shown, the robotic gripper 100 for flipping various types of refrigerator liners is used to flip refrigerator liners by grasping and clamping them, and then flipping and transporting the refrigerator liners. The robotic gripper 100 for flipping various types of refrigerator liners includes: a frame component 110; a first robotic gripper 120, which is fixedly mounted on the frame component 110; a width adjustment component 130, which is mounted on the frame component 110; and a second robotic gripper 140, which is mounted on the width adjustment component 130 and forms a clamping space 101 with the first robotic gripper 120. The first robotic gripper 120 and the second robotic gripper 140 can cooperate to clamp the refrigerator liners to flip them. The width adjustment component 130 can adjust the width of the clamping space 101 between the second robotic gripper 140 and the first robotic gripper 120.

[0026] It should be noted that, in this embodiment of the present invention, the frame component 110 is used to install components such as the width adjustment component 130 and the first robot gripper 120. The first robot gripper 120 and the second robot gripper 140 are used to form the clamping space 101 and clamp the refrigerator liner. In this embodiment of the present invention, the width adjustment component 130 is mounted on the frame component 110, and the second robot gripper 140 is mounted on the width adjustment component 130. The width adjustment component 130 enables the second robot gripper 140 to move relative to the frame component 110, that is, the width adjustment component 130 can adjust the distance between the second robot gripper 140 and the first robot gripper 120, thereby adjusting the width of the clamping space 101 to accommodate air conditioner liners of different widths. The robot gripper 100 for flipping multiple types of refrigerator liners provided in this embodiment of the present invention can perform mixed production flipping and handling of various types of refrigerator liners in a flexible production line; it meets the requirements of width recognition and automatic adjustment during mixed production, realizing mixed production flipping and handling of various types of refrigerator liners.

[0027] It should also be noted that the frame component 110 can be assembled from high-strength aluminum alloy profiles using connectors and fasteners to form a robust rectangular main frame that conforms to the contour of the refrigerator's inner liner opening. This assembly structure not only achieves lightweighting and reduces the robot's load requirements but also ensures sufficient structural rigidity to withstand the tilting inertial moment. In an optional embodiment, an aluminum support plate 112 is provided at the middle and rear of the frame component 110. The aluminum support plate 112, located at the middle and rear of the frame, is used to support the crossbeams of the French-style refrigerator's inner liner, ensuring that the refrigerator remains flat during gripping.

[0028] like Figure 3 As shown, in an optional embodiment, the width adjustment assembly 130 includes a width sensor 131, an adjustment drive structure 132, and a gripper mounting component 133. The second robot gripper 140 is mounted on the gripper mounting component 133, and the gripper mounting component 133 is slidably engaged with the frame component 110. The width sensor 131 is mounted on the gripper mounting component 133, and the adjustment drive structure 132 is mounted on the frame component 110 and is connected to the gripper mounting component 133 in a transmission manner, so that the gripper mounting component 133 slides relative to the frame component 110, thereby adjusting the width of the clamping space 101.

[0029] It should be noted that the gripper mounting component 133 is used to mount the second robot gripper 140 and slides in cooperation with the frame component 110. The adjustment drive structure 132 is mounted on the frame component 110 and is connected to the gripper mounting component 133 for driving the gripper mounting component 133 to slide relative to the frame component 110. The width sensor 131 is used to sense the width of the refrigerator liner so that the adjustment drive structure 132 can adjust the gripper mounting component 133 and the second robot gripper 140.

[0030] Optionally, the width sensor 131 can be a width-sensing limit switch, which is electrically connected to the adjustment drive structure 132 to adjust the gripper mounting 133 and the second robot gripper 140 mounted on the gripper mounting 133. Of course, it is not limited to this. In other embodiments of this utility model, the width sensor 131 can also be other structures, and this utility model does not make specific requirements or limitations on this.

[0031] Further, in an optional embodiment, the adjustment drive structure 132 includes an adjustment motor 1321, a transmission wheel 1322, and a transmission belt 1323. The adjustment motor 1321 is mounted on the frame component 110, the transmission wheel 1322 is connected to the adjustment motor 1321, the transmission belt 1323 is connected to the transmission wheel 1322, and the gripper mounting component 133 is fixed on the transmission belt 1323. The adjustment motor 1321 is used to drive the transmission wheel 1322 to rotate, the transmission wheel 1322 is used to drive the transmission belt 1323 to move, and the transmission belt 1323 is used to drive the gripper mounting component 133 to move linearly. The adjusting motor 1321 is mounted on the frame component 110. The transmission wheel 1322 is used to cooperate with the transmission belt 1323, which is connected to the gripper mounting component 133. Through the transmission wheel 1322 and the transmission belt 1323, the output motion of the adjusting motor 1321 is converted into the linear motion of the gripper mounting component 133, thereby realizing the position adjustment of the second robot gripper 140 relative to the first robot gripper 120, so that the first robot gripper 120 and the second robot gripper 140 can clamp the refrigerator liner, realizing the flipping and handling of the refrigerator liner. Synchronous belt drive has the characteristics of smoothness, low noise, and long transmission distance, and can realize the adjustment of the gripper mounting component 133 and the clamping space 101.

[0032] It should be noted that the transmission method of the adjustment drive structure 132 is not limited to the transmission belt 1323 and the transmission wheel 1322. In other embodiments of this utility model, the adjustment drive structure 132 can also adopt other transmission methods, such as cylinders, gear rack and pinion structures, etc. This utility model does not make specific requirements or limitations in this regard. Optionally, the adjustment motor 1321 can be a servo motor.

[0033] Furthermore, in an optional embodiment, the frame component 110 is provided with a first linear guide rail 111, and the gripper mounting component 133 is provided with a second linear guide rail 1331 that slides with the first linear guide rail 111. When the transmission belt 1323 drives the gripper mounting component 133 to move, it can drive the second linear guide rail 1331 to slide along the first linear guide rail 111.

[0034] As shown in the figure, optionally, in this embodiment, the second linear guide rail 1331 includes two sets, which are respectively disposed on both sides of the gripper mounting member 133. The first linear guide rail 111 corresponds to the second linear guide rail 1331, and the transmission belt 1323 is connected to the middle of the gripper mounting member 133.

[0035] It should be noted that the first linear guide rail 111 and the second linear guide rail 1331 can precisely guide the second robot gripper 140, ensuring smooth and wobbly movement. In this embodiment of the invention, the adjusting motor 1321 drives the gripper mounting piece 133, which is equipped with the width sensor 131, to move via the transmission wheel 1322 and the transmission belt 1323. When the width sensor 131 confirms that it has contacted the actual side of the refrigerator liner, the adjusting motor 1321 immediately stops, thereby accurately matching the current width of the refrigerator liner. In addition, since the condenser tube is slidable, it can be filtered out by the width sensor 131 with appropriate force during the edge-finding process, avoiding false triggering.

[0036] As shown in the figure, in an optional embodiment, the second robot gripper 140 includes a gripper assembly 141, a gripper chuck 142, and a clamping cylinder 143. The gripper assembly 141 is connected to the gripper mounting component 133, the clamping cylinder 143 is mounted on the gripper assembly 141, and the clamping cylinder 143 is connected to the gripper chuck 142 in a transmission connection.

[0037] It should be noted that the first robot gripper 120 and the second robot gripper 140 can adopt similar or identical structures. Furthermore, the arc-shaped baffle 144 is provided with mounting holes 1441, through which the gripper 142 protrudes. In an optional embodiment, the second robot gripper 140 further includes an arc-shaped baffle 144, which is connected to the gripper assembly 141. The arc-shaped baffle 144 is mainly used for guidance and has an anti-snagging function. Arc-shaped baffles 144 are installed on both sides of the opening of each gripper 142 (i.e., at the positions corresponding to the mounting holes 1441) to ensure that the condenser tubes do not snag on the grippers when released from the housing.

[0038] Furthermore, in an optional embodiment, the second robotic gripper 140 further includes a pad 145, which is connected to the gripper chuck 142. Optionally, the pad 145 may be made of polyurethane material, which has moderate elasticity, a high coefficient of friction, and excellent wear resistance. This effectively prevents hard contact from scratching the surface of the refrigerator liner and increases friction to prevent the refrigerator liner from slipping during the flipping process.

[0039] Please refer to the following: Figures 1 to 3The present invention provides a robotic gripper 100 for flipping multiple types of refrigerator liners: a frame component 110 is used to install components such as a width adjustment component 130 and a first robotic gripper 120. The first robotic gripper 120 and the second robotic gripper 140 are used to form a clamping space 101 and clamp the refrigerator liners. In this embodiment, the width adjustment component 130 is mounted on the frame component 110, and the second robotic gripper 140 is mounted on the width adjustment component 130. The width adjustment component 130 enables the second robotic gripper 140 to move relative to the frame component 110, that is, the width adjustment component 130 can adjust the distance between the second robotic gripper 140 and the first robotic gripper 120, thereby adjusting the width of the clamping space 101 to accommodate air conditioner liners of different widths. The robotic gripper 100 for flipping multiple types of refrigerator liners provided in this embodiment can perform mixed production flipping and handling of various types of refrigerator liners in a flexible production line; it meets the requirements of width recognition and automatic adjustment during mixed production, realizing mixed production flipping and handling of various types of refrigerator liners.
