Description

Technical Field

[0001] The utility model provides a stamping feeding robot, belonging to the technical field of robots. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. As a special type of robotic equipment, the stamping loading robot has the characteristics of high efficiency, precision and flexibility, which is significantly different from other robots. It focuses on the loading and unloading links in the stamping process. Through high-speed and high-precision positioning capabilities, it can accurately place the workpiece to be processed on the punch press, and then remove the processed workpiece from the punch press. Compared with traditional manual operations, the stamping loading robot has higher work efficiency and stability. At the same time, its operating procedures can be flexibly adjusted and programmed to adapt to workpieces of different sizes and shapes, realizing the diversification and adaptability of the production line.

[0003] The existing stamping feeding robot can basically meet the use needs, but when grabbing materials, the gripper assembly currently used by the robot often only sucks the top of the material through the pneumatic suction cup, and then transports the material to the stamping machine for stamping. This will cause the material to fall if the pneumatic suction cup is too heavy. The firmness and stability of material grabbing need to be improved, which has certain safety hazards. Based on this, the utility model provides a stamping feeding robot. Utility Model Content

[0004] The technical problem solved by the utility model is that the gripper assembly used by the robot often only sucks the top of the material through the pneumatic suction cup, which may cause the material to fall if it is too heavy. The firmness and stability of the material gripping needs to be improved, which poses certain safety hazards.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a stamping feeding robot, comprising a base, a multi-section matching mechanical arm is arranged on the top of the base, the end of the last section of the mechanical arm is rotatably connected to a connecting piece, and the side wall of the connecting piece is provided with a gripper assembly, and the gripper assembly includes a mounting seat, a plurality of pneumatic suction cups are equidistantly arranged on the bottom of the mounting seat, and electric push rods are symmetrically arranged on the side walls around the mounting seat, the telescopic rod end of the electric push rod is fixedly connected to a support plate, and the lower wall of the support plate is elastically connected to a clamping plate arranged on the outside of the pneumatic suction cup for clamping materials.

[0006] Furthermore, each of the side walls of the clamping plates that are away from each other are symmetrically provided with limiting rods that pass through the support plate, and the limiting rods are sleeved with a buffer spring that is placed between the support plate and the clamping plate.

[0007] Furthermore, a stopper is provided at the end of the limit rod and is arranged outside the support plate.

[0008] Furthermore, anti-slip pads are provided on the side walls of each of the pressing plates that are close to each other.

[0009] Furthermore, the side wall of the electric push rod is symmetrically provided with a reinforcing rib 1 fixedly connected to the side wall of the mounting seat.

[0010] Furthermore, a second reinforcing rib fixedly connected to the upper wall of the support plate is provided on the rod body of the telescopic rod end of the electric push rod.

[0011] Beneficial effects of the utility model:

[0012] When grabbing and feeding, the pneumatic suction cup sucks the top of the material. After the pneumatic suction cup sucks the top of the material, the electric push rod is started to drive the support plate to move toward the side close to the pneumatic suction cup, and then drives the clamping plate to move toward the pneumatic suction cup until the clamping plate is tightly fitted with the side wall of the material. At this time, the limit rod moves backward a certain distance, so that the buffer spring is under compression. On the basis of the pneumatic suction cup sucking the top of the material, the material can be further flexibly clamped and fixed between the clamping plates, thereby enhancing the firmness and stability of material grabbing, effectively avoiding the situation where the material is too heavy and falls, and reducing safety hazards.

[0026] Principle of the utility model

[0027] During use, under the action of the external control system, the multi-section coordinated mechanical arm 2 adjusts its position to drive the gripper assembly 4 to move to the top of the material to be loaded, and connects multiple pneumatic suction cups 6 to the external pneumatic system, so that when grabbing and loading, the pneumatic suction cup 6 sucks the top of the material. After the pneumatic suction cup 6 sucks the top of the material, the electric push rod 7 is started to drive the support plate 8 to move toward the side close to the pneumatic suction cup 6, and then drives the clamping plate 9 to move close to the pneumatic suction cup 6 until the clamping plate 9 is tightly fitted with the side wall of the material. At this time, the limit rod 10 moves backward a certain distance, so that the buffer spring 11 is under force and is in a compressed state. On the basis of the pneumatic suction cup 6 sucking the top of the material, the material can be further flexibly clamped and fixed between the clamping plates 9, thereby enhancing the firmness and stability of material grabbing, effectively avoiding the situation where the material is too heavy and falls, and reducing safety hazards.
