Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum foil box production technology, specifically to a gripping device for irregularly shaped products. Background Technology
[0002] In the food industry, aluminum foil boxes are frequently used for packaging during production.
[0003] Currently, on aluminum foil box production lines, the gripping and unloading process mostly relies on manual labor or relatively traditional mechanical devices. Manual operation is not only inefficient, but also prone to errors due to fatigue, affecting product quality and production progress. Traditional mechanical devices, on the other hand, often lack precision and flexibility in their gripping and unloading actions, making it difficult to adapt to aluminum foil boxes of different specifications and shapes. Furthermore, the stability and reliability of traditional devices need to be improved on high-speed production lines. Utility Model Content

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the connector is externally connected to a robotic arm, and the top of the connector is provided with several mounting holes.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the shape of the opening and the inner cavity of the inner frame is rectangular, square or star-shaped.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the mounting bracket and the inner frame are detachably connected by a first bolt.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the mounting bracket and the outer frame are detachably connected by a second bolt.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a first sealing element is provided at the connection between the inner frame and the mounting bracket, and a second sealing element is provided at the end face connection between the inner frame and the outer frame.
[0011] The beneficial effects of this utility model are as follows: This device is used to pick up and stack irregularly shaped aluminum foil boxes and to unload them. The inner frame cavity is set according to the shape and size of the product. The opening on the side of the outer frame is connected to an external air source. Suction creates a negative pressure inside the cavity, thereby adsorbing the product into the inner cavity of the inner frame. Multiple products can be picked up at one time, improving production efficiency. Attached Figure Description

[0019] See attached diagram. Figures 1 to 4The irregular product gripping device in this embodiment includes a connector 1, a mounting bracket 2, an inner frame 3 and an outer frame 4. The inner frame 3 and the outer frame 4 enclose a negative pressure cavity. The outer frame 4 is provided with an opening 40. The surface of the inner frame 3 is provided with a plurality of fine holes 30. One end of the outer frame 4 is provided with an opening 41. The opening 41 and the inner cavity shape of the inner frame 3 can be selectively set.
[0020] In this embodiment, a negative pressure cavity is formed by the inner frame 3 and the outer frame 4. An opening 40 is provided on the outer frame 4, and a number of fine holes 30 are provided on the surface of the inner frame 3. When the negative pressure is activated, a uniform and stable adsorption force is generated through the fine holes 30, which can firmly grasp irregularly shaped products, greatly improving the stability and reliability of the grasping, effectively avoiding the slippage or displacement of products during the grasping process, and ensuring the smooth progress of the production process.
