[0053] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0054] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0055] Figure 1 is a schematic diagram of the exploded structure of the gripper device. Figure 1 As shown, the clamping device includes a clamping assembly 10 and a hook assembly 20. The hook assembly 20 is connected to the clamping assembly 10, and the clamping assembly 10 is covered by the hook assembly 20.

[0056] like Figure 1As shown, in this schematic embodiment, the clamping assembly 10 includes a first jaw 12, a second jaw 14 and a first driving member 16. The first jaw 12 is provided with four first jaw portions 13, each of which has a first jaw surface 131. The second jaw 14 is slidably disposed on the first jaw 12 along a first direction D1. The second jaw 14 is provided with four second jaw portions 15, each of which has a second jaw surface 151, and each first jaw surface 131 is opposite to a second jaw surface 151. The first driving member 16 is disposed on the first jaw 12. In this schematic embodiment, the first driving member 16 is, for example, a cylinder, but is not limited thereto. The first driving member 16 is connected to the second jaw 14 and drives the second jaw 14 to move back and forth along the first direction D1, so that the first jaw surface 131 moves away from or approaches the second jaw surface 151. The first driving member 16 is used to drive the first clamping jaw 12 to slide relative to the second clamping jaw 14 to adapt to the sizes of radiator packaging boxes of various styles, so as to clamp the radiator packaging boxes, thereby effectively improving the compatibility of the clamping jaw device.

[0057] like Figure 1 As shown, in this exemplary embodiment, the hook assembly 20 includes a connecting mechanism 22 , a hook mechanism 24 and a third driving member 26 . Figure 2 It is a structural schematic diagram of a schematic implementation of a hook mechanism. Figure 3 This is another structural diagram of the claw mechanism. Figure 2 and Figure 3 As shown, the hook mechanism 24 includes a support frame 242, five first pulleys 244, five belts 247, a second driving member 246 and five hooks 248. The support frame 242 is connected to the connecting mechanism 22. The support frame 242 is provided with five support rods 243 at intervals. Each first pulley 244 is rotatably sleeved on the support rod 243, and the axes of each first pulley 244 are parallel and located in the same plane. The belt 247 is wound around the second driving member 246 and the first pulley 244. The second driving member 246 is arranged at the end of the support frame 242. The second driving member 246 drives the first pulley to rotate by the belt 247 wound around the second driving member 246 and the first pulley 244. Each hook 248 is sleeved on the belt 247, and each hook 248 is located between two support rods 243. The third driving member 26 is arranged on the connecting mechanism 22. In this exemplary embodiment, the third driving member 26 is, for example, a cylinder, but is not limited thereto. The third driving member 26 is connected to the hook mechanism 24 to drive the hook mechanism 24 to move back and forth along the first direction D1, thereby facilitating the grasping of heat sinks of different shapes and improving the compatibility of the clamping device.

[0058] The clamping device provided by the present invention can clamp the packaging box of the radiator according to different styles of radiators and their packaging boxes by changing the relative position between the first clamping jaw 12 and the second clamping jaw 14 of the clamping assembly 10, and at the same time, the hook assembly 20 can be moved according to the position of the radiator so that the hook mechanism 24 hooks the radiator, which can effectively improve production efficiency and reduce production costs.

[0059] Figure 4 is a schematic structural diagram of an exemplary embodiment of a clamping device. Figure 1 and Figure 4 As shown, in this exemplary embodiment, the connecting mechanism 22 includes a connecting plate 222, two sliding parts 224 and a connecting member 226. The connecting plate 222 is connected to the first clamping jaw 14, and the third driving member 26 is arranged above the connecting plate 222 and penetrates the clamping assembly 10. The connecting plate 222 is provided with an opening 223. The two sliding parts 224 are respectively arranged at the ends of the connecting plate 222 and are located below the connecting plate 222. Each sliding part 224 includes a slide groove 2243 and a slider 2245, the slide groove 2243 is connected to the connecting plate 222, and the slider 2245 is connected to the support frame 242 and is movably inserted into the slide groove 2243 along the first direction D1. The connecting member 226 is passed through the opening 223 and is respectively connected to the third driving member 26 and the support frame 242. The third driving member 26 and the connecting member 226 drive the support frame 242 fixedly connected to the slider 2245 to move back and forth in the slide groove 2243 along the first direction D1, thereby driving the movement of the claw mechanism 24 to ensure that various styles of radiators can be hooked, thereby further improving the compatibility of the clamping device.

[0060] like Figure 2 As shown, in this exemplary embodiment, the hook mechanism 24 further includes a limit frame 241. The limit frame 241 is connected to the support frame 242 and is located below the support frame 242. The limit frame 241 is provided with a plurality of limit holes 2413 corresponding to the number of hooks 248. Each hook 248 is respectively penetrated through each limit hole 2413. By limiting the movement of the hook 248 within the range of the limit hole 2413, the hook 248 is prevented from following the movement of the belt 247 and causing the hook 248 to be stuck on the support frame 242, thereby ensuring the safety of the clamping device.

[0061] like Figure 3 As shown, in this exemplary embodiment, the hook mechanism 24 further includes a plurality of fixing rods 249. The number of the fixing rods 249 is consistent with the number of the hooks 248. Each fixing rod 249 is passed through the hook 248. The fixing rod 249 is located at the limiting hole 2413 and the two ends are respectively mounted on the limiting frame 241. This ensures that the hook 248 can firmly hook the radiator to prevent the radiator from falling.

[0062] like Figure 2and Figure 3 As shown, in this exemplary embodiment, the second driving member 246 includes a driving motor 2461, a driving wheel 2463, a driven wheel 2465 and five second pulleys 245. The driven wheel 2465 is rotatably arranged on the support frame 242 coaxially with each second pulley 245. The driving motor 2461 drives the driven wheel 2465 to rotate through the belt 247 wound around the driving wheel 2463 and the driven wheel 2465, thereby driving each second pulley 245 to rotate. The driving motor 2461 drives each second pulley 245 and the first pulley 244 to rotate clockwise and counterclockwise, thereby driving the hook 248 sleeved on the belt 247 to move back and forth along the first direction D1, so that the hook 248 can hook or release multiple radiators at the same time, thereby improving production efficiency.

[0063] Figure 5 is a schematic diagram of a schematic implementation of a radiator grab assembly. Figure 5 As shown, the grabbing assembly of the radiator includes a mechanical arm 30 and a clamping device as described above. The first clamping jaw 12 of the clamping device is fixedly connected to the mechanical arm 30. The mechanical arm 30 grabs the radiator and its packaging box through the clamping jaw device and places them at the feed inlet position of the production equipment, effectively improving production efficiency and reducing labor costs.
