[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] Example 1: like Figure 1-2 As shown, a self-resetting gripper device includes a crossbeam 1, with second connecting rods 6 at both ends of the crossbeam 1. The second connecting rods 6 pass through the middle of a gripper frame 3. A first connecting rod 5 is provided at the top of the gripper frame 3. A cylinder 4 is provided on the crossbeam 1. The bottom end of the cylinder 4 and the piston rod end of the cylinder 4 are respectively sleeved on the first connecting rod 5. A gripping unit is provided at the bottom end of the gripper frame 3. Mounting plates 9 are provided at the ends of the gripper frame 3 and the bottom of the crossbeam 1. A spring 11 is provided between the two mounting plates 9. An adjusting pin 10 is provided on the mounting plate 9. The two ends of the spring 11 are respectively fixed to the two adjusting pins 10.

[0020] The cylinder 4 is connected to an external air source, and the spring 11 is in a stretched state. When clamping, the cylinder 4 first vents air to retract the piston rod, causing the two claws 3 to open. Then the cylinder 4 depresses air, and the claws 3 are pulled inward by the tension of the spring 11, so that the claw plate 8 contacts the product and firmly clamps the two sides of the product.

[0021] The self-resetting gripper device of this embodiment opens the two gripper frames 3 with a single cylinder 4 and uses the elastic force of the spring 11 to make the gripper automatically reset, adaptively clamping products of different sizes. It has a simple structure and can be quickly controlled and debugged.

[0022] The top of the cross frame 1 is provided with a mounting flange 2; the mounting flange 2 can easily fix the cross frame 1 to the end of the robot.

[0023] The clamping unit includes a horizontal plate 7, which is fixed to the inner side of the bottom of the claw frame 3. Several claw plates 8 are evenly distributed on the inner side of the horizontal plate 7. The horizontal plate 7 can increase the length of the clamping unit, and the arrangement of multiple claw plates 8 can reduce the weight of the clamping unit while maintaining the clamping effect.

[0024] The claw plate 8 is arc-shaped.

[0025] A photoelectric sensor 12 is provided in the middle of the crossbar 1; the emitting end of the photoelectric sensor 12 faces the product and is used to detect whether there is a product.

[0026] The adjusting pin 10 has a threaded portion on its outer side, and the mounting plate 9 has a threaded hole. The adjusting pin 10 is threaded into the threaded hole. The adjusting pin 10 can adjust the length of its extension into the mounting plate 9, adjust the tension of the spring 11, and thus adjust the clamping force of the claw plate 8.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
