Description

Technical Field

[0001] The invention relates to the technical field of industrial robots, in particular to a cutting industrial robot for furniture production. Background Art

[0002] Industrial robots are commonly used equipment in industrial production to replace manual operations. In the process of furniture production, some metal materials need to be cut to reach the usable size. At this time, in order to improve production efficiency, cutting industrial robots are often used to operate.

[0003] In the prior art, a Chinese patent with authorization announcement number CN116021582A discloses a multi-station water jet cutting industrial robot, including a water jet cutting mechanism, wherein the water jet cutting mechanism includes a water jet cutting robot, wherein the outer wall of the water jet cutting robot is fixedly connected with a fixed leg, and the outer wall of the fixed leg is fixedly connected with a holding bin away from the bottom of the water jet cutting robot, and the outer wall of the holding bin is fixedly connected with a water jet buffer mechanism, and the outer wall of the fixed leg is fixedly connected with a debris processing mechanism, and the larger debris is collected by a filter net so that the larger debris is located on the filter net, and the debris can directly withstand the impact of the water jet, thereby reducing the impact of the water jet on the filter net and ensuring the protection of the filter net, and the collection bin stores the falling water flow and debris, and the water and the debris are separated by the setting of the filter plate, and then the water pump is sucked to transport the water to the water jet cutting robot again for reuse, which has the characteristics of strong practicality.

[0004] The above-mentioned device utilizes a water jet to cut the workpiece when in use, but in actual use the cut workpiece needs to be manually removed from the filter screen. The low degree of automation of the manual operation in this process makes the overall work more cumbersome, and it is easy to be dangerous if the staff's hands are close to the water jet mechanism.

[0005] Moreover, in the prior art, a Chinese patent with authorization announcement number CN207534176U discloses an industrial robot three-dimensional laser cutting machine, comprising a cutting machine housing and a robotic arm, a cutting machine base is welded at the bottom end of the cutting machine housing, a feed door is installed on the other side of the cutting machine housing, a guide rail is welded on one side of the inner top surface of the cutting machine housing, a moving base is installed in the guide rail, a main robotic arm is installed at the mounting position on the bottom surface of the moving base, a laser cutting knife is installed at the other end of the main robotic arm, a mechanical gripper is installed at the other end of the secondary robotic arm, a workbench is installed in the middle of the bottom plate inside the cutting machine housing, the center position of the bottom surface of the workbench is connected to a drive motor through a transmission shaft, and through the cooperation of the robotic arm, the laser cutting knife and the mechanical gripper, the workpiece can be cut in three dimensions, and the cut workpiece can be flipped at the same time, thereby improving work efficiency and saving costs.

[0006] The above-mentioned device utilizes a laser cutting knife to cut the workpiece when in use. However, in actual use, the workpiece (especially the metal workpiece) will produce certain burrs attached to the cutting position during cutting. The burrs cause the workpieces to be scratched when stacked on each other, thereby causing scratches that affect the quality of the workpiece. Summary of the invention

[0011] A receiving plate with a "concave"-shaped structure is fixedly installed in the middle position inside the operating platform, and the receiving plate is used to receive the cutting burrs polished off. An automatic guiding mechanism is arranged on the inner side of the receiving plate, and the received polishing burrs are automatically discharged by the automatic guiding mechanism.

[0019] Preferably, the automatic guiding mechanism includes a guide plate rotatably mounted inside the receiving plate and a collecting box fixedly mounted on the outer surface of the operating platform, and an extrusion cam rotatably mounted inside the operating platform is provided below the receiving plate, and the extrusion cam rotates synchronously with the transmission screw through a transmission belt.

[0020] Preferably, a telescopic rod connected to the receiving plate is arranged directly above the squeezing cam, and a return spring is arranged outside the lower end of the telescopic rod, and the squeezing cam cooperates with the return spring to drive the guide plate to move reciprocally up and down.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the cutting industrial robot for furniture production adopts a new structural design, and its specific contents are as follows:

[0022] 1. An automatic unloading mechanism is set up. After the cutting manipulator completes the cutting of the workpiece, the automatic unloading mechanism is used to remove the workpiece. First, the vacuum of the fixed suction cup is used to adsorb and fix the workpiece, and then the transmission screw drives the movable block to move the workpiece to the recessed platform position of the operating platform, and then the workpiece is put down, thereby realizing automatic unloading of the workpiece after cutting and improving the overall work efficiency;

[0023] Furthermore, in the process of the transmission screw driving the movable block, the movable block is used to drive the extrusion plate below to move synchronously, and finally the extrusion plate is used to squeeze the airbag inside the operating platform. When the airbag is squeezed, the air inside is ejected through the through hole to clean the surface of the stacked cutting workpieces, thereby removing the surface debris;

[0024] Furthermore, the magnetic adsorption effect between the electromagnetic block and the grinding block allows the cutting robot to drive the grinding block to move synchronously, so that the grinding block can grind the cutting position of the workpiece after cutting, thereby achieving the purpose of removing burrs, and the upper friction block and the lower friction block are movably connected by a connecting rod, so that the grinding block as a whole can adapt to cutting workpieces of different thicknesses.

[0025] 2. A receiving plate is set inside the operating platform, and the residue generated when cutting the workpiece falls into the receiving plate inside the operating platform through the groove, thereby preventing the residue from accumulating at the cutting position and affecting the subsequent cutting operation.

[0026] Furthermore, an automatic guiding mechanism is arranged inside the receiving plate, and the residue in the receiving plate is discharged into the collection box for collection by the automatic guiding mechanism. During the rotation of the transmission screw, the transmission belt drives the extrusion cam to rotate synchronously. The extrusion cam cooperates with the reset spring to make the telescopic rod extend and retract up and down, so that the telescopic rod pushes the guide plate to vibrate up and down, thereby guiding the residue into the collection box, which is convenient for subsequent cleaning.
