AI Technical Summary
In existing technologies, when changing production materials, robotic arms need to change different grippers due to the different sizes of the materials, resulting in a waste of resources and costs.
Design a mechanical gripper, including an adapter assembly, a gripper assembly, a correction assembly, and a height sensor. By adjusting the distance and position between the suction cup and the adapter plate, it can adapt to materials of different sizes, achieve polygonal adjustment, and enable the flexible use of multiple grippers.
This allows for the replacement of grippers without changing materials; only the position of the suction cup needs to be adjusted, reducing resource and cost waste and improving the adaptability and efficiency of the robotic arm.

Abstract
Description
Technical Field
[0001] This field relates to automation, and more specifically to a mechanical gripper. Background Technology
[0002] In existing technologies, production lines typically use robotic arms to handle materials. When changing production materials, different grippers are required for the robotic arms to handle materials of different sizes. This renders some grippers disposable production tools, resulting in significant waste of resources and costs. Utility Model Content
[0003] The purpose of this utility model is to provide a mechanical gripper, and the specific technical solution is as follows:
[0004] A mechanical gripper includes: an adapter assembly comprising an adapter sleeve and an adapter plate, one end of the adapter sleeve being fixedly connected to the adapter plate and the other end of the adapter sleeve being connected to a robotic arm; a gripper assembly comprising an adjustment plate and a suction cup, one end of the adjustment plate being fixedly connected to the adapter plate and the suction cup being movably disposed at the other end of the adjustment plate, the suction cup being used to connect to or disconnect a material tray; the gripper assembly is configured in multiple groups, and the multiple groups of gripper assemblies are arrayed around the adapter plate.
[0005] The adjustment plate has a strip-shaped hole, and the suction cup is installed in the strip-shaped hole. The distance between the suction cup and the adapter plate is adjusted within the strip-shaped hole.
[0006] It also includes: a correction component, which includes a base and an imaging device. The base is fixedly mounted on the adapter plate, and the imaging device is movably mounted on the base. The imaging device is used to provide position information of the material tray.
[0007] It also includes: a height sensor, with two height sensors, each fixedly mounted on the adapter plate, used to measure the height of the material tray.
[0008] The adapter plate has an array of mounting holes, which allow for adjustment of the relative position of the adapter plate when it is fixed to other components.
[0009] The above-mentioned technical solution of this utility model has the following beneficial technical effects: by making the suction cup movable, the size of the polygon formed by multiple suction cups can be controlled by adjusting the distance between the suction cup and the adapter plate, so as to correspond to different sizes of material trays to be transported, so that when changing materials, only the position of the suction cup needs to be adjusted. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model;
[0011] The components are: 1-adapter sleeve, 2-adapter plate, 3-adjustment plate, 4-suction cup, 5-base, 6-imaging device, 7-height sensor, and 8-material tray. Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0013] A mechanical gripper includes: an adapter assembly comprising an adapter sleeve 1 and an adapter plate 2, one end of the adapter sleeve 1 being fixedly connected to the adapter plate 2, and the other end of the adapter sleeve 1 being connected to a robotic arm; and a gripper assembly comprising an adjusting plate 3 and a suction cup 4, one end of the adjusting plate 3 being fixedly connected to the adapter plate 2, and the suction cup 4 being movably disposed at the other end of the adjusting plate 3, the suction cup 4 being used to connect to or disconnect a material tray 8; the gripper assembly is configured in multiple sets, with multiple sets of gripper assemblies arrayed around the adapter plate 2. By movably distributing the suction cup 4, the size of the polygon formed by the multiple suction cups 4 can be controlled by adjusting the distance between the suction cup 4 and the adapter plate 2, thereby accommodating material trays 8 of different sizes to be transported, so that only the position of the suction cup 4 needs to be adjusted when changing materials.
[0014] The adjusting plate 3 has a strip-shaped hole, and the suction cup 4 is installed in the strip-shaped hole. The suction cup 4 adjusts the distance between itself and the adapter plate 2 within the strip-shaped hole.
[0015] It also includes: a correction component, which includes a base 5 and an imaging device 6. The base 5 is fixedly mounted on the adapter plate 2, and the imaging device 6 is movably mounted on the base 5. The imaging device 6 is used to provide position information of the material tray 8.
[0016] It also includes: height sensors 7, of which two are fixedly mounted on the adapter plate 2. The height sensors 7 are used to measure the height of the material tray 8. When the heights of the two points on the material tray 8 are the same, it means that the material tray 8 is flat. If the heights of the two points are different, it means that the tray is tilted and the suction cup 4 needs to be adjusted.
[0017] The adapter plate 2 is provided with an array of mounting holes, which allows the relative position of the adapter plate 2 to be adjusted when it is fixed with other components.
