Description

Technical Field

[0001] This utility model relates to the field of board throwing machines, specifically a dual-arm robotic board throwing machine. Background Technology

[0002] During the processing of sheet products, stacked products need to be separated and transported one by one. However, existing sheet product feeding equipment cannot be adjusted according to the spacing between products or the size of the sheet material, thus limiting the handling process.

[0003] Patent application number 202223482689.5 discloses a palletizer, belonging to the field of material handling device technology. The palletizer includes a motor, a support frame, a lifting screw, a loading platform, and a loading limit component. The lifting screw is mounted on the support frame. The motor, lifting screw, and loading platform are sequentially connected and driven. The lifting screw drives the loading platform to move up and down to transport materials. The loading limit component can detect whether the height of the material on the loading platform exceeds a preset height value. The preset height value corresponds to the height of the material corresponding to the allowable load of the palletizer. When the height of the material exceeds the preset height value, the loading limit component controls the palletizer to stop operating.

[0004] The above technical solution uses a loading platform to support the board. However, since the position of the loading platform is constant, it lacks positioning when conveying smaller boards, resulting in poor conveying stability. When conveying larger boards, it is difficult to fully support the board, and it cannot meet the needs of feeding and conveying boards of different sizes. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a dual-arm robotic plate-throwing machine to solve the technical problems of lack of positioning when conveying smaller plates due to the constant position of the loading platform, poor conveying stability, difficulty in fully supporting larger plates when conveying them, and inability to meet the plate-throwing and conveying needs of plates of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-arm robotic plate-throwing machine, comprising symmetrically arranged robotic plate-throwing arms and an adjustment assembly installed between the two robotic plate-throwing arms. A telescopic plate is slidably inserted into the robotic plate-throwing arm, and a vacuum suction frame is provided at the bottom end of the telescopic plate. Both sides of the top surface of the robotic plate-throwing arm are fixed with protrusions. The adjustment assembly includes symmetrically arranged double-threaded screws and a meshing mechanism installed between the two double-threaded screws. The two ends of the double-threaded screws with opposite thread directions are respectively threaded into multiple protrusions.

[0007] The present invention is further configured such that a second telescopic cylinder is embedded in the side wall of the robot throwing arm, and one end of the telescopic plate extending into the robot throwing arm is fixedly connected to the second telescopic cylinder.

[0008] The present invention is further configured such that positioning rods are fixed on both sides of the top surface of the vacuum adsorption frame, and the positioning rods are slidably inserted into the telescopic plate.

[0009] The present invention is further configured such that a first telescopic cylinder is fixedly installed at the top of the telescopic plate, and the bottom end of the first telescopic cylinder is fixedly connected to the vacuum adsorption frame.

[0010] The present invention is further provided that vacuum holes are provided on both sides of the bottom end face of the vacuum adsorption rack, and a rubber sealing plate with a frame structure is fixed on the vacuum adsorption rack.

[0011] The present invention is further configured such that vacuum generators are installed on both sides of the top surface of the vacuum adsorption rack, and the bottom end of the vacuum generator is connected to the vacuum hole.

[0012] The present invention is further configured such that the meshing mechanism includes a synchronous pulley fixedly sleeved on a double-threaded screw and a synchronous belt sleeved on the two synchronous pulleys, wherein a knob is fixedly sleeved on one of the double-threaded screws.

[0013] The present invention is further configured such that both ends of the double threaded screw are rotatably sleeved with mounting plates, and fastening bolts are embedded in both sides of the bottom end face of the mounting plates, and a servo motor connected to the double threaded screw is fixed to the side wall of the mounting plates.

[0014] In summary, the present invention has the following advantages: By setting an adjustment component between the two robot throwing arms, the servo motor drives the double threaded screw to rotate after starting. The two double threaded screws rotate synchronously through a synchronous wheel and a synchronous belt, and the protrusion drives the robot throwing arm to move during the rotation, thereby adjusting the distance between the two robot throwing arms and the vacuum suction frame. By adjusting the distance of the vacuum suction frame, it is suitable for conveying plates of different sizes.

[0015] Vacuum generators are installed on both sides of the top surface of the vacuum adsorption frame. The rubber sealing plate at the bottom of the vacuum adsorption frame is in contact with the plate and keeps it sealed. The vacuum generator adsorbs air through the vacuum hole and then fixes it to the plate, so that the plate remains stable during the conveying process. A first telescopic cylinder is installed on the top of the telescopic plate. After the first telescopic cylinder is started, it drives the vacuum adsorption frame and the fixed plate to rise and fall. A second telescopic cylinder is installed on the side wall of the robot's plate-throwing arm. After the second telescopic cylinder is started, it drives the telescopic plate to slide in the robot's plate-throwing arm and adjusts the position of the adsorbed plate during the sliding process, which facilitates the adsorption and conveying of the plate.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] A dual-arm robotic paddleboard launcher, such as Figure 1-4 As shown, the device includes symmetrically arranged robotic throwing arms 1 and an adjustment assembly installed between the two robotic throwing arms 1. A telescopic plate 6 is slidably inserted into the robotic throwing arm 1, and a vacuum suction frame 4 is provided at the bottom end of the telescopic plate 6. Both sides of the top surface of the robotic throwing arm 1 are fixed with protrusions 14. The adjustment assembly includes symmetrically arranged double-threaded screws 8 and a meshing mechanism installed between the two double-threaded screws 8. The two ends of the double-threaded screws 8 with opposite thread directions are respectively threaded into multiple protrusions 14.

[0023] Vacuum suction rack 4 has vacuum holes 10 on both sides of its bottom end face, and a frame-shaped rubber sealing plate 9 is fixed on the vacuum suction rack 4. Vacuum generators 2 are installed on both sides of the top end face of the vacuum suction rack 4. The bottom end of the vacuum generator 2 is connected to the vacuum hole 10. The rubber sealing plate 9 at the bottom end of the vacuum suction rack 4 is in contact with the plate and keeps it sealed. The vacuum generator 2 is fixed to the plate after absorbing air through the vacuum hole 10, so that the plate remains stable during the conveying process. The meshing mechanism includes a synchronous pulley 12 fixedly sleeved on a double-threaded screw 8 and a synchronous belt 11 sleeved on the two synchronous pulleys 12. A knob 13 is fixedly sleeved on one of the double-threaded screws 8. Both ends of the lead screw 8 are rotatably sleeved with mounting plates 15. Fastening bolts 17 are embedded in both sides of the bottom end face of the mounting plate 15. A servo motor 16 connected to the double-threaded lead screw 8 is fixed to the side wall of the mounting plate 15. The fastening bolts 17 are threaded into the support frame or equipment housing to keep the mounting plate 15 fixed. After the servo motor 16 is started, it drives the double-threaded lead screw 8 to rotate. The two double-threaded lead screws 8 rotate synchronously through the synchronous pulley 12 and the synchronous belt 11. During the rotation, the protrusion 14 drives the robot plate-throwing arm 1 to move, thereby adjusting the distance between the two robot plate-throwing arms 1 and the vacuum adsorption frame 4. Adjusting the distance of the vacuum adsorption frame 4 is suitable for conveying plates of different sizes.

[0024] Furthermore, a second telescopic cylinder 7 is embedded in the side wall of the robot throwing arm 1, and one end of the telescopic plate 6 extending into the robot throwing arm 1 is fixedly connected to the second telescopic cylinder 7. Positioning rods 3 are fixed on both sides of the top surface of the vacuum adsorption frame 4. The positioning rods 3 are slidably inserted into the telescopic plate 6. A first telescopic cylinder 5 is fixedly installed on the top of the telescopic plate 6, and the bottom end of the first telescopic cylinder 5 is fixedly connected to the vacuum adsorption frame 4.

[0025] The working principle of this utility model is as follows: During use, the second telescopic cylinder 7 pushes out the telescopic plate 6, causing the vacuum adsorption frame 4 to move to the top of the plate. The first telescopic cylinder 5 drives the vacuum adsorption frame 4 to move downward, so that the rubber sealing plate 9 at the bottom of the vacuum adsorption frame 4 is tightly connected to the plate. The vacuum generator 2 is started and adsorbs air through the vacuum hole 10 and then fixes it to the plate. After the first telescopic cylinder 5 is started, it drives the vacuum adsorption frame 4 and the fixed plate to rise and fall. After the second telescopic cylinder is started, it drives the telescopic plate 6 to slide in the robot loading arm 1, and moves the adsorbed plate during the sliding process. When conveying plates of different sizes, the servo motor 16 is started to drive the double threaded screw 8 to rotate. The two double threaded screws 8 rotate synchronously through the synchronous wheel 12 and the synchronous belt 11. During the rotation, the protrusion 14 drives the robot loading arm 1 to move, thereby adjusting the distance between the two robot loading arms 1 and the vacuum adsorption frame 4. Adjusting the distance of the vacuum adsorption frame 4 is suitable for conveying plates of different sizes. After the servo motor 16 is damaged, the double threaded screw 8 can be rotated by the knob 13.
