Description

Technical Field

[0001] The present invention relates to the technical field of industrial equipment, and in particular to a robot gripper. Background Art

[0002] The manufacturing process of sheet metal electric control cabinets includes welding. After welding, the workpiece needs to be polished to remove welds and burrs. In traditional manual operations, workers need to hold a grinder in a dusty and noisy environment, which poses a great health hazard. In a system where robots perform polishing operations, the workpiece to be polished needs to be fixed with a fixture, and then processed by the polishing robot. If multiple work surfaces need to be polished, a flip table needs to be added, which complicates the process. Summary of the invention

[0003] The purpose of the present invention is to provide a sheet metal electric control cabinet grinding and handling robot gripper to solve the above technical problems. The technical problems solved by the present invention can be achieved by adopting the following technical solutions:

[0004] A sheet metal electric control cabinet grinding and handling robot gripper, comprising:

[0005] A claw frame, which is a square metal frame with grooves, used as the basis for mounting other components;

[0006] a first clamping assembly mounted on a first side of the gripper frame, wherein the first clamping assembly is connected to a reciprocating mechanism;

[0007] A second clamping assembly is installed on the short side reciprocating mechanism, and the second clamping assembly is located on a second side of the gripper frame adjacent to the first side.

[0008] Preferably, a connecting flange is provided on the top of the gripper frame for connecting to the robot body.

[0009] Preferably, it also includes a magnetic suction cup assembly, which is arranged in the middle of the bottom of the gripper frame.

[0010] Preferably, it also includes a suction cup lifting mechanism, which is arranged at the bottom of the gripper frame and connected to the magnetic suction cup assembly.

[0011] Preferably, the first clamping assembly and the second clamping assembly are both provided with a guide rod cylinder, and the guide rod cylinder is connected to the clamping fingers.

[0012] Preferably, a wear-resistant polyurethane layer is provided on the contact surface between the clamping fingers and the workpiece.

[0013] Preferably, an anti-drop hook is provided next to the clamping finger.

[0014] Preferably, a plurality of hard stops are provided on the inner side of the first clamping assembly.

[0015] Preferably, the gripper frame is also provided with an air knife for cleaning dust generated by grinding.

[0016] The beneficial effects of the above technical solution are:

[0017] Using robots instead of manual labor for loading can protect workers' health and reduce labor costs; at the same time, the multifunctional gripper can provide transportation and workpiece reversing, eliminating the transition of the turning table and improving work efficiency and flexibility.

[0021] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0024] A sheet metal electric control cabinet grinding and handling robot gripper, comprising:

[0025] A gripper frame 1, which is a square metal frame with grooves and is used as a base for installing other components; except for installing components such as the cylinder, the rest of the gripper frame is completely cut out to provide a larger grinding space;

[0026] A first clamping assembly 3 is installed on a first side of the gripper frame, and the first clamping assembly 3 is connected to a reciprocating mechanism 2; the reciprocating mechanism is used for displacement;

[0027] A second clamping assembly 4 is mounted on the short side reciprocating mechanism, and the second clamping assembly is located on a second side adjacent to the first side of the gripper frame 1. The two clamping assemblies are used to grasp and fix the workpiece.

[0028] A connection flange 5 is provided on the top of the gripper frame 1 for connecting with the robot body. The flange connection is characterized by a firm and reliable connection and high stability.

[0029] It also includes a magnetic suction cup assembly 6, which is arranged in the middle of the bottom of the gripper frame 1.

[0030] It also includes a suction cup lifting mechanism 7, which is arranged at the bottom of the gripper frame 1 and connected to the magnetic suction cup assembly 6. For the flat plate parts that do not need to be polished in the sheet metal materials of the electric control cabinet, when they need to be transported, the magnetic suction cup assembly is pushed out by the suction cup lifting mechanism, and the flat plate parts are adsorbed by the magnetic suction cup. When not in use, the magnetic suction cup is retracted by the suction cup lifting mechanism.

[0031] The first clamping assembly 3 and the second clamping assembly 4 are both provided with a guide rod cylinder 8, and the guide rod cylinder 8 is connected to the clamping finger 9. The guide rod cylinder provides a maximum range for clamping the workpiece.

[0032] A wear-resistant polyurethane layer is provided on the contact surface between the clamping finger 9 and the workpiece. Polyurethane is a soft material that can increase the friction during grasping while avoiding damage to the workpiece.

[0033] An anti-drop hook is arranged beside the clamping finger 9 to prevent the workpiece from falling.

[0034] The inner side of the first clamping assembly 3 is provided with multiple hard stops. The design of multiple hard stops can be compatible with workpieces of various specifications within the cylinder stroke, thereby increasing the adaptability of the present invention. When grabbing a workpiece, the outer wall of the workpiece is first clamped by the first clamping assembly, and then the inner wall is clamped. The reciprocating mechanism brings the first clamping assembly with the workpiece against the hard stop, and then the outer wall and inner wall of the long side are clamped by the second clamping assembly, thereby firmly grabbing the entire workpiece.

[0035] The gripper frame 1 is also provided with an air knife for cleaning dust generated by grinding. The air knife can blow air to the loading and unloading workpieces and the transport contact surface, reducing the accumulation of dust and metal chips generated by grinding, increasing the service life of the equipment and ensuring that the workpiece is not damaged by metal chips.

[0036] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
