[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] Example 1 like Figures 1 to 5 As shown, the present invention provides a suction cup robot for sheet metal, including a mounting base 1; a robot arm 2 mounted on the mounting base 1; a suction cup mounting base 3 horizontally mounted at the end of the robot arm 2 away from the mounting base 1; multiple gripper assemblies 4 are provided, and the multiple gripper assemblies 4 are arrayed on the top surface of the suction cup mounting base 3; a suction cup assembly 5 is mounted on the bottom surface of the suction cup mounting base 3; the gripper assembly 4 includes a gripper seat 41 movably mounted on the top surface of the suction cup mounting base 3, and a clamping cylinder 42 is provided on the side wall of the gripper seat 41, the clamping cylinder 42 being movable... The plunger is equipped with a gripper 43, and the end of the gripper 43 away from the clamping cylinder 42 is equipped with an anti-adhesion gripper assembly 6; the suction cup assembly 5 includes a suction cup plate 51 set on the bottom surface of the suction cup mounting base 3, and the suction cup plate 51 is connected to the negative pressure mechanism 53 set on the mounting base 1 through a hose 52; the suction cup plate 51 has a hollow structure, and the interior of the suction cup plate 51 is connected to the negative pressure mechanism 53 through a hose 52; multiple grooves 511 are arranged in an array on the suction cup plate 51, and multiple suction holes 512 are provided on the end face of the suction cup plate 51 away from the suction cup mounting base 3.
[0027] The mounting base 1 can be installed at the position where the board needs to be clamped. The robot arm 2 can drive the suction cup mounting base 3, the gripper assembly 4 and the suction cup assembly 5 to move closer to the board (the board is stacked in order from top to bottom), so that the board can be adsorbed and clamped by the gripper assembly 4 and the suction cup assembly 5.
[0028] Based on the size of the sheet material, the clamping cylinder 42 is activated to adjust the position of the grippers 43, ensuring that each gripper 43 is located on the outside of the sheet material. Then, the robot arm 2 moves the suction cup assembly 5 towards the top sheet material (the groove 511 on the suction cup plate 51 reduces the overall weight of the suction cup plate 51). When the suction cup plate 51 in the suction cup assembly 5 comes into contact with the top sheet material, the negative pressure mechanism 53 generates negative pressure, which allows the top sheet material to be adsorbed onto the suction cup plate 51 through the suction hole 512. Then, the clamping cylinder 42 is activated to move the adjusting grippers 43 towards the side wall of the top sheet material, thus clamping the side wall of the top sheet material and preventing it from falling off after being adsorbed.
[0029] The anti-adhesion claw assembly 6 is designed to prevent the lower layers of the board from sticking together when the uppermost layer of the board is being clamped.
[0030] The robotic arm 2 is existing technology, which can drive the suction cup mounting base 3 to move in both horizontal and vertical directions, so it will not be described in detail here.
[0031] Example 2 Based on Example 1, such as Figures 1 to 3 As shown, the top surface of the suction cup mounting base 3 is provided with multiple parallel guide grooves 31, and the gripper seat 41 is slidably disposed in the guide groove 31 at the corresponding position; there are two guide grooves 31 and four gripper assemblies 4, and a gripper seat 41 is slidably disposed at both ends of the length direction in each guide groove 31; a double-headed cylinder 32 is horizontally disposed in the guide groove 31, and the two piston rods of the double-headed cylinder 32 are respectively connected to the gripper seats 41 at both ends of the guide groove 31; the extension and retraction direction of the piston rod of the clamping cylinder 42 is the same as the length direction of the guide groove 31.
[0032] Depending on the size of the material to be gripped, the distance between the two gripper seats 41 can be adjusted by activating the double-headed cylinder 32 (the two gripper seats 41 on the same guide groove 31 can slide to adjust the distance), which facilitates the gripper 43 to hold materials of different sizes and improves the applicability of this material suction cup robot.
[0033] The four gripper components 4 are designed to ensure that the material is gripped evenly, improve stability, and prevent the material from falling off during transfer.
[0034] Example 3 Based on Example 1, such as Figure 1 , Figures 4 to 7As shown, the anti-adhesion claw assembly 6 includes a connecting seat 61, which is movably connected to the bottom surface of the gripper 43 via an adjusting rod 62; an electromagnet 63 is disposed on the bottom surface of the gripper 43 away from the adjusting rod 62; a magnetic plate 64 is embedded in the connecting seat 61, and the position of the electromagnet 63 corresponds vertically to the position of the magnetic plate 64, with the electromagnet 63 and the magnetic plate 64 magnetically attracted to each other; a telescopic cylinder 65 is disposed on the bottom surface of the connecting seat 61; an anti-adhesion rod 66 is disposed on the piston rod of the telescopic cylinder 65; the adjusting rod 62 includes a fixed cylinder 621, which is disposed on the bottom surface of the gripper 43; the adjusting cylinder 622 is coaxial with the fixed cylinder 621, and the adjusting cylinder 622 is fixedly disposed on the connecting seat 61, with the end of the adjusting cylinder 622 away from the connecting seat 61 movably inserted into the fixed cylinder 621; the end of the adjusting cylinder 622 away from the connecting seat 61 is connected to the fixed cylinder 621 via a connecting spring 623.
[0035] The extension and retraction direction of the piston rod of the telescopic cylinder 65 is the same as that of the piston rod of the clamping cylinder 42, which helps to improve the clamping stability of the sheet metal.
[0036] When the upper layer of the board is gripped, that is, when the suction cup plate 51 in the suction cup assembly 5 comes into contact with the uppermost board, the clamping cylinder 42 is activated, which moves the adjusting gripper 43 towards the side wall of the uppermost board. The adjusting gripper 43 clamps the uppermost board onto the side wall. At this time, the position of the anti-adhesion rod 66 corresponds to the position of the board below the board gripped by the suction cup plate 51. The telescopic cylinder 65 is activated, which pushes the anti-adhesion rod 66 to come into contact with the multiple layers of boards below the board gripped by the suction cup plate 51. When the robot arm 2 moves the suction cup mounting base 3, the gripper assembly 4, and the suction cup assembly 5 to move the uppermost board upward, the upper and lower boards can be separated. Because the anti-adhesion rod 66 is clamped on the side wall of the multi-layer board, under the action of the weight of the multi-layer board, when the robot arm 2 moves the uppermost board upward, the adjusting cylinder 622 can slide inside the fixed cylinder 621, increasing the length between the adjusting cylinder 622 and the fixed cylinder 621, and simultaneously stretching the connecting spring 623, thus preventing the boards from sticking together. After the uppermost board is adsorbed and picked up, the telescopic cylinder 65 can be activated to retract the anti-adhesion rod 66, separating the anti-adhesion rod 66 from the lower multi-layer board (at the same time, under the action of the resetting connecting spring 623, the adjusting cylinder 622 retracts and slides into the fixed cylinder 621), thus completing the adsorption and picking up of the board.
[0037] The height of the anti-adhesion rod 66 can be made to match the thickness and size of the plates to be clamped, so that the anti-adhesion rod 66 can clamp multiple plates at the same time, thereby preventing the adhesion between the upper and lower plates.
[0038] Example 4 Based on Example 1, such as Figure 3 , Figures 6 to 7 As shown, the gripper 43 has a vertical clamping surface 431 on its side wall near the suction cup mounting base 3. After the clamping cylinder 42 is activated, the adjusting gripper 43 moves towards the side wall of the uppermost plate. The vertical clamping surface 431 on the gripper 43 can then come into contact with the side wall of the plate to be clamped, which helps to increase the contact area between the gripper 43 and the plate, thereby improving the gripping firmness of the gripper 43 on the plate.
[0039] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
