With the above arrangement, the gripping structure of this embodiment utilizes the unique hole-shaped sheet metal structure characteristics of the component 10 to be gripped, and the first gripping portion 41 and the second gripping portion 42 of the gripping mechanism act on its inner hole, and through the external expansion gripping method, the universal adaptable gripping function of the components 10 to be gripped of different specifications and models can be realized. By making the movable seat 1 movable and driving the mounting component 2 to rotate through the driving assembly 3, the automatic unloading and automatic loading functions of the component 10 to be grasped are realized, the workload of employees is reduced, and the technical problem of low transfer efficiency of sheet metal parts for manufacturing home appliances in related technologies is solved.

[0031] Specifically, in some embodiments, the component 10 to be grasped is a sheet metal cover panel of an air conditioner, or a similar object with a through hole.

In this way, by setting a cylinder, the effect of pushing the mounting component 2 to rotate can be achieved, thereby conveniently realizing the transfer of the component 10 to be grabbed.

[0033] In the grabbing structure of this embodiment, see Figure 1 , Figure 2 The driving assembly 3 includes a second driving cylinder 32, which is arranged on a side of the mounting component 2 close to the connecting portion 33, a push rod 321 is connected to the piston rod of the second driving cylinder 32, a movable groove 22 for the push rod 321 to pass through is provided on the mounting component 2, the push rod 321 is movably arranged in the movable groove 22, and the first grasping portion 41 is connected to the push rod 321. In this way, the second driving cylinder 32 is located on a side of the mounting component 2 away from the component 10 to be grasped, and when the grasping structure performs a grasping operation, the second driving cylinder 32 will not contact the component 10 to be grasped, thereby avoiding the risk of collision of the component 10 to be grasped.

[0034] See also Figure 2 In the grabbing structure of this embodiment, the first connecting member 21 includes a first connecting plate 211 and a second connecting plate 212 arranged at intervals, between which the connecting portion 33 is relatively rotatably connected to the first connecting plate 211 and the second connecting plate 212; the piston rod of the second driving cylinder 32 is passed through the first connecting plate 211 and the second connecting plate 212.

With the above arrangement, the grabbing operation of a plurality of components 10 to be grabbed can be realized, thereby improving the working efficiency.

[0043] In the grabbing structure of this embodiment, see Figure 1 The support frame 11 is provided with a guide rail 111, and the second mounting frame 13 is provided with a slider 131 slidably connected to the guide rail 111. By driving the second mounting frame 13 to move, the distance between the first mounting frame 12 and the second mounting frame 13 is adjusted. In this way, by adjusting the distance between the first mounting frame 12 and the second mounting frame 13, the grasping operation of the components 10 to be grasped of different specifications can be adapted.

[0045] The clamping structure of the present embodiment adopts a multi-station design, which can reduce the frequency of the movement of the grasping structure back and forth between the unloading point and the discharging point, thereby improving the efficiency of automated operations; similarly, the number of stations and the relative positions between the stations can be adjusted as needed according to the number of panels and the relative positions of the arrangements when the materials are incoming. Based on this requirement, the present embodiment adds a drive component 3 for adjusting the relative positions between the stations to accommodate hangers of different specifications and models, thereby improving the compatibility and adaptability of the grasping structure; the grasping structure itself has a simple structure, and most of them use pneumatic drive components 3, which is convenient for the later replacement and maintenance of the grasping structure, and has lower maintenance costs.

[0046] The part 10 to be grasped in the present embodiment is a sheet metal outer cover panel, and a driving component 3 is added to the grasping structure to adjust the relative position of the grasping structure, that is, the relative position of the sheet metal outer cover panel when picking up materials; since the hanger hook has a certain inclination angle, the role of adding the driving component 3 is to imitate the material picking action of tilting the panel to a certain angle before manual unloading. Tilting the sheet metal outer cover panel helps to remove the sheet metal outer cover panel smoothly, thereby greatly improving the success rate of unloading materials by the grasping structure.

[0047] In the grabbing structure of this embodiment, the grabbing structure uses a gear rack to realize the synchronous expansion clamping function driven by a single drive assembly 3; the grabbing structure uses the hole-shaped sheet metal structure characteristics unique to the sheet metal cover panel, and acts on the inner hole of the sheet metal cover panel. Through the expansion grabbing method, the universal grabbing function of panels of different specifications and models can be realized, further improving the compatibility and adaptability of the clamp.
