Description

Technical Field

[0001] The utility model belongs to the technical field of manipulators, and in particular relates to a manipulator for rubber processing. Background Art

[0002] Rubber products refer to the activities of producing various rubber products with natural and synthetic rubber as raw materials, and also include rubber products reproduced from waste rubber. During the production and processing of these rubber products, a variety of equipment and mechanisms are required, the most common of which is the need to use a manipulator for grasping the rubber products. For example, the existing patent with publication number CN208888936U discloses "a manipulator, including a motor, a right manipulator seat, a screw, an optical axis, a left manipulator seat, a left manipulator, a right manipulator and a transmission device, the right manipulator seat is provided with a right manipulator, the left manipulator seat is provided with a left manipulator, the optical axis passes through one end of the left manipulator seat and one end of the right manipulator seat respectively to limit the left manipulator seat and the right manipulator seat to only be able to move axially close or away at the same time." It can be seen that the application describes a common manipulator, which can be installed on the robotic arm of an industrial robot and assembled on a rubber product processing production line to realize the picking and transportation of rubber products during processing;

[0003] However, in actual use, the existing manipulator in the above patent does not have any protective structure designed on the inner side of the two clamping jaws. Direct contact with rubber products in the later stage may cause the surface of the rubber products to be squeezed and damaged, affecting the qualified rate of the products. At the same time, the clamping jaws are directly fixed on the movable seat, and cannot be quickly disassembled, assembled and replaced according to rubber products of different specifications, which reduces the overall flexibility of use. For this reason, the present utility model proposes a manipulator for rubber processing. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] See also Figures 1 to 3 , is an embodiment of the present utility model, which provides a technical solution: a rubber processing robot, comprising

[0023] A mounting seat 1, two side seats 2 symmetrically welded and fixed to one side of the mounting seat 1, two movable seats 6 symmetrically and movably mounted between the two side seats 2, and a clamping claw 7 mounted on the front end of the movable seat 6;

[0024] The disassembly and assembly mechanism 9 includes a U-shaped socket 93 welded and fixed to the rear end surface of the clamping jaw 7, a rectangular slot 94 provided on the front end surface of the movable seat 6, a movable card plate 91 movably mounted on the side of the movable seat 6, a movable card block 92 welded and fixed to the side of the movable card plate 91, and a limiting card hole 95 passing through the surface of the U-shaped socket 93. The U-shaped socket 93 is inserted into the rectangular slot 94, and the movable card block 92 passes through the U-shaped socket 93 through the limiting card hole 95. After passing through, the movable card block 92 can plug the U-shaped socket 93 and the movable seat 6 together to complete the rapid installation of the clamping jaw 7. Subsequently, it is only necessary to move the movable card plate 91 sideways to release the limit of the U-shaped socket 93, thereby realizing the rapid disassembly and assembly of the clamping jaw 7.

[0025] The protective rubber pad 8 installed on the inner surface of the clamping jaw 7 can prevent the clamping jaw 7 from causing extrusion damage to the surface of the rubber product when the clamping jaw 7 clamps the rubber product, thereby ensuring the yield rate of the rubber product processing;

[0026] The driving structure includes a motor 5 fixed to the left side of one of the side seats 2 by screws and a bidirectional screw 3 rotatably installed between the two side seats 2, and the output end of the motor 5 is connected to the bidirectional screw 3, and the movable seat 6 is threadedly connected to the bidirectional screw 3. When the motor 5 is started later, it drives the bidirectional screw 3 to rotate. Because the threads at both ends of the bidirectional screw 3 are in opposite directions and the movable seat 6 is threadedly connected to the bidirectional screw 3, when the bidirectional screw 3 rotates, the two movable seats 6 can move towards each other, thereby achieving the action of clamping or loosening the rubber product;

[0027] The guide structure includes a guide rod 4 fixed between the two side seats 2, and the top end of the movable seat 6 is slidably sleeved on the surface of the guide rod 4, so that the movable seat 6 can be guided and limited when moving laterally without rotating.

[0028] A side hole communicating with the rectangular slot 94 is formed on the side surface of the movable seat 6 , and the side hole corresponds to the movable block 92 , so as to facilitate smooth penetration and subsequent movement of the movable block 92 .

[0029] The end of the movable rod 99 passes through the side of the movable seat 6 and is connected to the movable clamping plate 91. Under the pushing action of the spring 98, the movable clamping plate 91 can be stably fitted to the side of the movable seat 6 during daily use, ensuring that the movable block 92 smoothly passes through the limit card hole 95, ensuring the limiting stability of the U-shaped socket 93 and the clamping claw 7. When the clamping claw 7 needs to be removed and replaced later, it is only necessary to pull the movable clamping plate 91 sideways, so that the movable rod 99 moves sideways with the inner slider 97 and compresses the spring 98, causing the movable block 92 to move out of the limit card hole 95 and no longer limit the U-shaped socket 93. At this time, the U-shaped socket 93 can be directly withdrawn from the rectangular slot 94, completing the quick disassembly and replacement of the clamping claw 7.

[0030] One end of the spring 98 abuts against the inner sliding block 97 , and the other end of the spring 98 abuts against the inner wall of the inner sliding groove 96 .

[0031] Among them, the side surface of the movable seat 6 is further provided with a rod hole communicated with the inner sliding groove 96, and the rod hole corresponds to the movable rod 99, allowing the movable rod 99 to pass through smoothly.

[0032] The protective rubber pad 8 can be removed and replaced smoothly by pulling the protective rubber pad 8 to the side, and the protective rubber pad 8 can be removed and replaced smoothly by pulling the protective rubber pad 8 to the side.

[0033] Among them, the protective rubber pad 8, the plug 102, and the triangular side block 103 are an integrated structure. All three are made of silicone material and will undergo elastic deformation when squeezed. A rectangular cavity is opened in the plug 102, so that the triangular side block 103 has sufficient deformation space when squeezed.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
