Description

Technical Field

[0001] The utility model relates to the field of toy production equipment, in particular to a toy production mechanical arm gripper. Background Art

[0002] During the toy production process, the toys need to be glued, painted, and other processing steps that require grippers to fix their position. During the processing step of fixing the toy's position, grippers are generally needed to clamp and fix the toy in mid-air to facilitate workers to perform fast and labor-saving processing. The functional design of the robotic arm grippers on the market is single, and they do not have the performance of flexible disassembly and assembly. At the same time, the clamping and positioning performance is poor, and the toys are prone to fall off, which cannot bring convenience to users.

It has the advantages of being easy to assemble and maintain, and can also achieve the function of grabbing toys more firmly.

[0005] In order to achieve the above utility model purpose, the specific scheme adopted by the utility model is:

[0006] A toy production robot arm gripper, comprising an oil cylinder fixedly connected to the robot arm by bolts, a moving block fixedly sleeved on the bottom end of the piston rod of the oil cylinder, the moving block reciprocating along a limit bar, the limit bar and an outer side plate one fixedly connected by bolts, the two ends of the moving block are respectively hinged to a moving side rod one and a moving side rod two, the other ends of the moving side rod one and the moving side rod two are both hinged to a gripper seat, the other end of the gripper seat is integrally formed and connected to a gripper for grabbing a toy, the upper and lower parts of the gripper close to the toy side are fixedly connected by bolts to an L-shaped protrusion to prevent the toy from falling.

[0007] Furthermore, grooves adapted to accommodate the limiting strips are provided in the middle of both sides of the moving block, and the friction between the grooves and the limiting strips is negligible.

[0008] Furthermore, there are two limit bars.

[0009] Furthermore, there are two movable side rods 1 and 2, and both are located on two sides of the movable block.

[0010] Furthermore, in the non-tilted working state, the connecting section and the bottom section between the gripper and the gripper seat are both inclined rod structures, the middle section of the gripper is a vertical rod structure, the angle between the vertical rod structure and the vertical inclined rod structure is an obtuse angle, and the angle range is: 135°-165°.

[0011] Furthermore, the other side of the gripper seat is in a U-shaped structure, and the inner side is fixed with the outer plate 2 by bolts.

[0012] The beneficial effects of the utility model are:

[0013] There is no complicated and redundant structure. The reciprocating motion is powered by the oil cylinder and executed by the piston rod. By moving the moving side rod 1 and the moving side rod 2, the distance between the grippers on both sides is driven to achieve the clamping and loosening of the toy. The L-shaped protrusion is added to increase the firmness of the toy to prevent looseness during processing. It is used in conjunction with a mechanical arm or a position where the toy needs to be fixed. It has the advantages of easy assembly and simple maintenance, and can also achieve the function of grabbing the toy more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
