Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to an anti-pinch gripper for industrial robots. Background Technology

[0002] The anti-pinch gripper for industrial robots belongs to the field of automated production equipment technology. Specifically, it involves an end effector used for handling, assembling or packaging precision workpieces. Its core function is to avoid product damage caused by excessive clamping force or contact stress concentration when gripping vulnerable parts.

[0003] A search revealed Chinese patent CN218659147U, which discloses an anti-pinch gripper for an industrial robot. The gripper includes a base plate with a slide rail. A connecting rod is slidably connected within the slide rail. A cylinder is fixed to the base plate to push the connecting rod back and forth. A pair of pull rods are symmetrically arranged at the top of the connecting rod, with a movable rod hinged to the front end of each pull rod. A docking plate is provided at the top of the slide rail, and the tail end of the movable rod is hinged to the docking plate. Clamping plates are symmetrically arranged at the top of the movable rod, and these clamping plates have an L-shaped structure. A screw is threaded onto the clamping plate, passing through the clamping plate and rotatably connected to the movable rod.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] While the aforementioned patent can achieve a certain degree of anti-pinch damage, it can only achieve clamping in one direction and cannot achieve stable clamping in other directions, resulting in poor clamping stability and thus having certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes an anti-pinch gripper for industrial robots, which can achieve a stable anti-pinch effect.

[0007] The technical solution to achieve the purpose of this utility model is as follows: an anti-pinch gripper for industrial robots, including a robotic arm, an installation cylinder fixedly installed at the end of the robotic arm, a controller fixedly installed on the robotic arm, a plurality of fixed posts fixedly installed at the bottom of the installation cylinder, a support block fixedly installed at the ends of the plurality of fixed posts, and a transmission component and a gripping component.

[0008] The transmission assembly is located inside the mounting cylinder.

[0009] The transmission assembly includes an electric telescopic rod fixedly installed at the top of the mounting cylinder. A pressure sensor is fixedly installed at the telescopic end of the electric telescopic rod, and a transmission column is fixedly installed at the end of the pressure sensor.

[0010] The gripping component is mounted on the support block.

[0011] The gripping component includes multiple concave grooves equidistantly formed on the support block, and each concave groove has a drive gear and a gripping claw rotatably mounted inside it.

[0012] In some embodiments, racks are fixedly mounted at equal intervals on the outer peripheral wall of the transmission column, and driven gears are fixedly mounted on the end of the gripping claws. The driving gear meshes with the racks and driven gears respectively.

[0013] In some embodiments, a plurality of fixed columns are fixedly installed between the electric telescopic rod and the support block, and the transmission column slides through the support block.

[0014] In some embodiments, a plurality of mounting plates are fixedly mounted on the inner sidewall of each of the gripping claws, and a rubber pad is fixedly mounted on one side of each of the mounting plates.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model uses an electric telescopic rod in the transmission assembly to stably move the transmission column and rack. Furthermore, through the meshing relationship between the gears and rack, it can stably rotate the gripping claw, thereby achieving stable gripping of objects. In addition, the rubber pads on the gripping claw can greatly improve the anti-pinch damage effect and enhance the protection of the gripped items.

[0017] Secondly, this utility model not only has a stable and highly reliable transmission structure, but also, through the setting of a pressure sensor, by setting a predetermined pressure value, when the gripping is stable, the electric telescopic rod cannot extend normally, which will generate pressure on the pressure sensor. When the pressure is the same as the predetermined pressure value, the work can be stopped, thereby further improving the effect of non-damaging clamping.

[0018] This solves the problem that while existing technologies can achieve a certain degree of anti-pinch damage, they can only achieve clamping in one direction and cannot achieve stable clamping in other directions, resulting in poor clamping stability. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] This utility model provides an improved anti-pinch damage gripper for industrial robots. The technical solution of this utility model is as follows:

[0029] like Figures 1-5 As shown, an anti-pinch gripper for an industrial robot includes a robotic arm 1, an installation cylinder 2 fixedly mounted at the end of the robotic arm 1, a controller 57 fixedly mounted on the robotic arm 1, a plurality of fixed posts 4 fixedly mounted at the bottom of the installation cylinder 2, and a support block 51 fixedly mounted at the ends of the plurality of fixed posts 4. It also includes a transmission assembly 3 and a gripping assembly 5. The installation cylinder 2 and the support block 51 provide a stable foundation for the installation of the transmission assembly 3 and the gripping assembly 5.

[0030] Transmission component 3 is installed inside mounting cylinder 2.

[0031] The transmission assembly includes an electric telescopic rod 31 fixedly installed at the top of the mounting cylinder 2. A pressure sensor 56 is fixedly installed at the telescopic end of the electric telescopic rod 31, and a transmission column 32 is fixedly installed at the end of the pressure sensor 56. The electric telescopic rod 31 and the transmission column 32 ensure that the transmission assembly 3 works normally, thereby driving the gripping assembly 5 to work. The pressure sensor 56 can effectively detect the gripping force and adjust the gripping force reasonably according to the size of different objects.

[0032] Grasping component 5 is set on support block 51.

[0033] The gripping component 5 includes multiple concave grooves 55 equidistantly formed on the support block 51. Each concave groove 55 has a drive gear 52 and a gripping claw 54 rotatably mounted inside it. The concave grooves 55 provide support for the installation of the components of the gripping component 5, thereby ensuring that the gripping component 5 can work normally.

[0034] Furthermore, racks 33 are fixedly installed at equal intervals on the outer peripheral wall of the transmission column 32, and driven gears 53 are fixedly installed at the end of the gripping claw 54. The driving gear 52 meshes with the racks 33 and driven gears 53 respectively. Through the meshing relationship of the gears, the transmission column 32 can smoothly drive the driving gears 52 and driven gears 53 to rotate, thereby driving the gripping claw 54 to rotate and achieve the gripping effect.

[0035] Furthermore, multiple fixed posts 6 are fixedly installed between the electric telescopic rod 31 and the support block 51, and the transmission post 32 slides through the support block 51. The multiple fixed posts 4 and 6 can greatly improve the stability of the gripping component 5 installation, thereby ensuring the stability of the gripping process.

[0036] Furthermore, multiple mounting plates 58 are fixedly installed on the inner wall of each gripper 54, and a rubber pad 59 is fixedly installed on one side of each mounting plate 58. The rubber pad 59 can further improve the protection effect on the object.

[0037] The specific working method is as follows: When it is necessary to grip an object, the robotic arm 1 moves the transmission component 3 and the gripping component 5. After moving to the appropriate position, the electric telescopic rod 31 in the drive component 3 moves the transmission column 32 and the rack 33. Through the meshing of the gear and the rack 33, the driving gear 52 and the driven gear 53 are rotated, thereby rotating the gripping claw 54, thus achieving the gripping and grasping of the object. The rubber pad 59 set can greatly improve the damage prevention effect.

[0038] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
