Description

Technical Field

[0001] This utility model relates to the field of stamping robot technology, and more specifically, to a CNC five-axis stamping robot. Background Technology

[0002] A stamping robot is an automated handling device specifically designed for stamping production lines. Through end effectors and workpiece fixing devices, it automatically completes tasks such as sheet metal loading, inter-process transfer, and finished product unloading, replacing manual labor in transferring workpieces between presses.

[0003] In existing technologies, vacuum suction cups are often used to suction the top of a workpiece, and then the end effector of the robot body moves the vacuum suction cup and the workpiece. However, the wide variety of workpieces and the fact that the vacuum suction cup cannot be moved greatly reduce the scope of application. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a CNC five-axis stamping robot that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a CNC five-axis stamping robot, including a robot body, on which an adsorption area adjustment mechanism is provided. The adsorption area adjustment mechanism includes...

[0007] A connecting rod is mounted on the robot body. A connecting plate is fixedly mounted on the bottom of the connecting rod. Several limiting grooves are opened on the bottom of the connecting plate, and the several limiting grooves are arranged in a circular array along the center of the connecting plate.

[0008] A limiting block is slidably installed inside a limiting groove. The bottom of the limiting block is integrally formed with a limiting frame, and a vacuum suction cup is installed at the bottom of the limiting frame.

[0009] In a preferred embodiment, a turntable is rotatably mounted inside the connecting plate. The turntable has an arc-shaped groove that runs vertically through it. The number of arc-shaped grooves is the same as the number of limiting grooves. A sliding shaft is rotatably mounted inside the arc-shaped groove. The bottom of the sliding shaft is fixedly connected to the top of the limiting block.

[0010] In a preferred embodiment, a gear ring is fixedly fitted onto the surface of the turntable, and a gear is rotatably mounted inside the connecting disc, the gear meshing with the gear ring.

[0011] In a preferred embodiment, a motor is mounted on the top of the connecting plate, and the output end of the motor is connected to the gear.

[0012] In a preferred embodiment, the limiting frame is provided with a friction increasing mechanism, which includes a crossbar that is fixedly installed on the side of the limiting frame away from the central axis of the connecting disc.

[0013] In a preferred embodiment, a connecting frame is fixedly installed on the side of the crossbar away from the limiting frame, a spring is installed on the side of the connecting frame near the vacuum suction cup, and a friction block is installed on the other end of the spring.

[0014] In a preferred embodiment, a vacuum pump is mounted on top of the connecting plate, and an air pipe is installed between the vacuum pump and the vacuum suction cup.

[0015] In a preferred embodiment, the vacuum pump is located at the center of the connecting plate, and the friction block is located below the vacuum suction cup.

[0016] The present invention provides a five-axis CNC stamping robot, the advantages of which include:

[0017] 1. By setting an adsorption area adjustment mechanism, the distribution of vacuum suction cups can completely cover the top of the workpiece. Then, the end effector of the robot body causes the vacuum suction cups to move downwards to adsorb the top of the workpiece. The end effector of the robot body then drives the workpiece to move. Compared with the prior art, the distribution position of the vacuum suction cups can be adjusted according to the area of ​​the top of the workpiece, which greatly improves the applicability of this device.

[0018] 2. By setting a friction-increasing mechanism, the friction block contacts the outer surface of the workpiece, thereby compressing the spring. Due to the spring's rebound force and the rough surface of the friction block, the friction between the workpiece and the friction block is increased. This avoids the problem that when the top of the workpiece has an opening or groove, the vacuum suction cup covering the opening or groove has a weak adsorption force, which can easily cause the workpiece to fall off due to insufficient adsorption force.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-4This utility model provides a technical solution: a CNC five-axis stamping robot, including a robot body 1. The robot body 1 is equipped with an adsorption area adjustment mechanism, which includes a connecting rod 201 and a limiting block 204. The connecting rod 201 is mounted on the end effector of the robot body 1. A connecting plate 202 is fixedly mounted on the bottom of the connecting rod 201 by bolts and a mounting plate. Several limiting grooves 203 are formed on the bottom of the connecting plate 202, and these grooves extend along the connecting plate 204. The 02 is arranged in a circular array at its center. The limiting block 204 is slidably installed inside the limiting groove 203. A limiting groove is formed on the inner wall of the limiting groove 203. A limiting strip is fixedly installed on the surface of the limiting block 204, and the limiting strip is slidably fitted inside the limiting groove 203, thus preventing the limiting block 204 from falling off due to its own weight. To reduce friction, ball bearings can also be installed on the limiting strip, and the ball bearings contact the inner wall of the limiting groove. A limiting frame 205 is integrally formed at the bottom of the limiting block 204. A vacuum suction cup 206 is installed at the bottom of the 05. By setting an adsorption area adjustment mechanism, when the user needs to move the workpiece, the robot body 1 is activated, so that the robot body 1 drives the vacuum suction cup 206 to move directly above the workpiece through the end effector. Several limiting blocks 204 move simultaneously inside the limiting groove 203, so that the vacuum suction cup 206 moves radially towards the side close to the central axis of the connecting plate 202 or away from the central axis of the connecting plate 202 until the distribution of the vacuum suction cup 206 can completely cover the top of the workpiece. Then, the end effector of the robot body 1 makes the vacuum suction cup 206 move downward until it contacts the top of the workpiece. Then, the vacuum pump 305 is activated to make the vacuum suction cup 206 adsorb the top of the workpiece, so that the end effector of the robot body 1 drives the workpiece to move. Compared with the prior art, the distribution position of the vacuum suction cup 206 can be adjusted according to the area of ​​the top of the workpiece, which greatly improves the applicability of this device.

[0027] Reference Figures 1-4 The connecting plate 202 has a turntable 207 rotatably mounted inside. The turntable 207 has an arc-shaped groove 208 that runs vertically through it. The number of arc-shaped grooves 208 is the same as the number of limiting grooves 203. A sliding shaft 209 is rotatably mounted inside the arc-shaped groove 208. The bottom of the sliding shaft 209 is fixedly connected to the top of the limiting block 204. By setting the turntable 207, when the turntable 207 rotates, the inner wall of the arc-shaped groove 208 squeezes the sliding shaft 209. Under the limiting cooperation of the limiting groove 203 and the limiting block 204, multiple sliding shafts 209 simultaneously drive the limiting block 204 to move. The limiting block 204 drives the vacuum suction cup 206 to move through the limiting frame 205.

[0028] Reference Figures 1-4A gear ring 210 is fixedly sleeved on the surface of the turntable 207. A gear 211 is rotatably installed inside the connecting plate 202. The gear 211 meshes with the gear ring 210. A motor 212 is installed on the top of the connecting plate 202. The output end of the motor 212 is connected to the gear 211. By setting the motor 212, the user starts the motor 212, which drives the gear 211 to rotate. Through the meshing connection between the gear 211 and the gear ring 210, the gear ring 210 drives the turntable 207 to rotate.

[0029] Reference Figures 1-4 The limiting frame 205 is equipped with a friction-increasing mechanism, which includes a crossbar 301. The crossbar 301 is fixedly installed on the side of the limiting frame 205 away from the central axis of the connecting plate 202. A connecting frame 302 is fixedly installed on the side of the crossbar 301 away from the limiting frame 205. A spring 303 is installed on the side of the connecting frame 302 near the vacuum suction cup 206. A friction block 304 is installed on the other end of the spring 303. A telescopic rod is installed between the friction block 304 and the connecting frame 302 to limit the movement direction of the friction block 304. The telescopic rod is sleeved inside the spring 303. A vacuum pump 305 is installed on the top of the connecting plate 202. An air pipe 306 is installed between the vacuum pump 305 and the vacuum suction cup 206. A part of the air pipe is sleeved inside the connecting frame 302, the crossbar 301, and the limiting frame 205. The vacuum pump 305 is located on the connecting plate 202. At the center of position 2, the friction block 304 is located below the vacuum suction cup 206. By setting a friction-increasing mechanism, when the user adjusts the distribution position of the vacuum suction cup 206, the limiting frame 205 drives the crossbar 301 and the connecting frame 302 to move simultaneously. Since the friction block 304 is located below the vacuum suction cup 206, during the process of the vacuum suction cup 206 moving from the upper outer side of the workpiece to directly above the workpiece, the friction block 304 contacts the outer side of the workpiece, thereby compressing the spring 303. Due to the rebound force of the spring 303 and the rough surface of the friction block 304, the friction between the workpiece and the friction block 304 is increased. This avoids the problem that when the top of the workpiece has an opening or groove, the vacuum suction cup 206 covering the opening or groove has a weak adsorption force, and the workpiece is prone to falling off due to insufficient adsorption force when moving.

[0030] Specifically, the working process or principle of this CNC five-axis stamping robot is as follows: When the user needs to move the workpiece, the robot body 1 is activated, causing the robot body 1 to move the vacuum suction cup 206 directly above the workpiece via the end effector. The motor 212 is then activated, driving the gear 211 to rotate. Through the meshing connection between the gear 211 and the gear ring 210, the gear ring 210 drives the turntable 207 to rotate. The inner wall of the arc-shaped groove 208 presses against the sliding shaft 209, causing multiple sliding shafts 209 to simultaneously move the limit block 204 under the limiting cooperation of the limiting groove 203 and the limit block 204, thus limiting the movement of the sliding shafts. Block 204 drives the vacuum suction cup 206 to move via the limiting frame 205. Since the friction block 304 is located below the vacuum suction cup 206, during the process of the vacuum suction cup 206 moving from the upper outer side of the workpiece to directly above the workpiece, the friction block 304 contacts the outer side of the workpiece until the distribution of the vacuum suction cup 206 can completely cover the top of the workpiece. Then, the end effector of the robot body 1 causes the vacuum suction cup 206 to move downward until it contacts the top of the workpiece. Then, the vacuum pump 305 is started to cause the vacuum suction cup 206 to adsorb the top of the workpiece, thereby driving the workpiece to move via the end effector of the robot body 1.
