Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically an eight-claw robotic arm assembly for cigarette rolling machines. Background Technology

[0002] In modern industry, the mechanization and automation of production processes have become prominent themes. However, in the machinery industry, processing and assembly are discontinuous processes. Relying solely on manual labor to connect these discontinuous production steps is not only time-consuming but also inefficient. Furthermore, the labor intensity is extremely high, and errors and injuries can sometimes occur. Clearly, this severely impacts and restricts the efficiency and automation level of the entire production process. The application of robotic grippers effectively solves this problem, eliminating the risk of repetitive, accidental errors. A robotic gripper, or grasping mechanism, is a component used to directly hold a workpiece. Due to the differences in the shape, size, weight, material properties, and surface condition of the workpiece being held, the hand structure of industrial robotic grippers varies greatly, with most structures designed according to specific workpiece requirements.

[0003] Existing eight-claw robotic arms for cigarette rolling machines suffer from low grasping accuracy, poor maneuverability, and insufficient stability. Furthermore, their functionality is limited to grasping items, failing to simplify the production process. Therefore, we propose an eight-claw robotic arm assembly for cigarette rolling machines to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an eight-claw robotic arm assembly for cigarette rolling machines, in order to solve the problems mentioned in the background art, such as low grasping accuracy, poor movement flexibility, and insufficient stability during use. Furthermore, the existing eight-claw robotic arms for cigarette rolling machines have a single function, which is limited to grasping items and cannot simplify the production process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an eight-claw manipulator assembly for a cigarette rolling machine, comprising a top plate, a bottom plate, and an eight-claw manipulator installed on the lower part of the top plate. The eight-claw manipulator includes a support ring, which is fixedly connected to the bottom of the top plate by eight sets of fixing rods. The fixing rods are distributed in a ring around the center of the support ring. Eight sets of gears are installed on the outer wall of the support ring, and the gears are also installed in a ring around the center of the support ring. The fixing rods and gears are staggered on the support ring. A cylinder is installed on the top of the top plate, and a cylinder rod is installed through the top plate at the bottom of the cylinder. A fixing post is installed at the bottom of the cylinder rod, and a rack is installed on the outer wall of the fixing post. The rack meshes with the gears, and claws are installed at the bottom of the gears.

[0006] Preferably, the gear is rotatably connected to the outer wall of the support ring via a bearing.

[0007] Preferably, an arc-shaped groove is provided on the lower part of the multiple sets of claws on the side near the center of the support ring, the claws are installed obliquely on the gear, and the oblique direction of the bottom of the claws is close to the center of the support ring.

[0008] Preferably, a mounting plate is installed at the rear end of the top plate, and a mounting box is installed at the other end of the mounting plate. A rotary motor is installed at the end of the inner wall of the mounting box near the mounting plate. A transmission shaft is installed on the output shaft of the rotary motor, and the transmission shaft passes through the mounting box and is fixedly connected to the mounting plate.

[0009] Preferably, a vertical plate is installed on the top of the base plate, a fixing plate is installed on the upper part of the front end of the vertical plate, a threaded rod is installed between the bottom of the fixing plate and the base plate, a drive motor is installed on the top of the threaded rod through the fixing plate, a nut seat is threaded to the outer wall of the threaded rod, a connecting plate is installed at the front end of the nut seat, and the mounting box is installed at the front end of the connecting plate.

[0010] Preferably, slide rails are installed on both sides of the front end of the upright plate, and sliders are slidably connected on the slide rails. The front ends of the two sliders are fixedly connected to the connecting plate.

[0011] Preferably, multiple sets of reinforcing plates are installed between the top of the rear end of the base plate and the upright plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model pushes the fixed column and rack downward by the cylinder. The rack and gear are meshed and connected to drive the gear to rotate around the support ring. The claw at the bottom of the gear rotates with the gear. Since the claw is installed at an angle and the bottom faces the center of the support ring, the gear can drive the claw to retract towards the center when it rotates, so as to achieve grasping. The support ring is connected to the top plate through eight sets of ring-shaped fixed rods, which can enhance the structural rigidity of the device and solve the problems of low grasping accuracy, poor movement flexibility and insufficient stability of the existing eight-claw manipulator for cigarette machines.

[0014] (2) When the drive shaft is rotated by the rotary motor, the entire eight-claw manipulator can be rotated, thereby adjusting the gripping angle. The drive motor drives the threaded rod to rotate, which can make the nut seat move up and down along the threaded rod, thereby driving the mounting box and top plate to rise and fall vertically. This can realize the height adjustment of round objects such as cigarettes held by the claws, solving the problem that the existing eight-claw manipulators used in cigarette machines have only one function, which is to grasp items, and cannot simplify the production process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an eight-claw robotic arm assembly for a cigarette rolling machine, comprising a top plate 1, a bottom plate 16, and an eight-claw robotic arm installed on the lower part of the top plate 1. The eight-claw robotic arm includes a support ring 3, which is fixedly connected to the bottom of the top plate 1 by eight sets of fixing rods 2. The fixing rods 2 are distributed in a ring around the center of the support ring 3. Eight sets of gears 4 are installed on the outer wall of the support ring 3, and the fixing rods 2 and gears 4 are installed in a ring around the center of the support ring 3. The fixing rods 2 and gears 4 are staggered on the support ring 3. A cylinder 6 is installed on the top of the top plate 1, and a cylinder rod 7 is installed through the bottom of the cylinder 6 and penetrates the top plate 1. A fixing post 8 is installed on the bottom of the cylinder rod 7, and a rack 9 is installed on the outer wall of the fixing post 8. The rack 9 meshes with the gears 4, and claws 10 are installed on the bottom of the gears 4. Please refer to [link to relevant documentation]. Figure 4 Gear 4 is rotatably connected to the outer wall of support ring 3 via bearing 5. (See also...) Figure 3The multiple claws 10 have an arc-shaped groove 11 on the side near the center of the support ring 3. The claws 10 are installed at an angle on the gear 4, and the angle of the bottom of the claws 10 is close to the center of the support ring 3. In use, the cylinder 6 at the top of the top plate 1 pushes the fixed column 8 downward through the cylinder rod 7, thereby causing the rack 9 on the outer wall of the fixed column 8 to move downward. Through the meshing connection between the rack 9 and the gear 4 on the outer wall of the support ring 3, the gear 4 can be driven to rotate around the support ring 3. The claws 10 at the bottom of the gear 4 rotate with the gear 4. Since the claws 10 are installed at an angle and the bottom faces the center of the support ring 3, the rotation of the gear 4 can drive the claws 10 to retract towards the center, and through the arc-shaped groove 11, they can adhere to round objects such as cigarettes to achieve gripping. When the cylinder rod 7 moves upward, the claws 10 open. The arc-shaped groove 11 at the lower part of the claw 10 can closely fit the arc surface of the cigarette, reducing slippage during gripping; the claw 10 is installed at an angle with its bottom facing the center, forming a centripetal clamping force when closed, improving gripping and positioning accuracy. The support ring 3 is connected to the top plate 1 through eight sets of annularly distributed fixing rods 2, which can enhance the structural rigidity of the device. Please refer to... Figure 2 A mounting plate 12 is installed at the rear end of the top plate 1, and a mounting box 13 is installed at the other end of the mounting plate 12. A rotary motor 14 is installed on the inner wall of the mounting box 13 near the mounting plate 12. A drive shaft 15 is installed on the output shaft of the rotary motor 14, and the drive shaft 15 passes through the mounting box 13 and is fixedly connected to the mounting plate 12. Please refer to [link / reference]. Figure 2 A vertical plate 17 is mounted on the top of the base plate 16. A fixed plate 18 is mounted on the upper part of the front end of the vertical plate 17. A threaded rod 19 is mounted between the bottom of the fixed plate 18 and the base plate 16. A drive motor 20 is mounted on the top of the threaded rod 19 through the fixed plate 18. A nut seat 21 is threadedly connected to the outer wall of the threaded rod 19. A connecting plate 24 is mounted on the front end of the nut seat 21. A mounting box 13 is mounted on the front end of the connecting plate 24. A rotary motor 14 at the rear end of the mounting plate 12 is fixedly connected to the top plate 1 through a drive shaft 15 and the mounting plate 12. When the rotary motor 14 drives the drive shaft 15 to rotate, it can drive the top plate 1 and the entire eight-claw manipulator to rotate, thereby adjusting the gripping angle. The drive motor 20 on the base plate 16 drives the threaded rod 19 to rotate, which can cause the nut seat 21 to move up and down along the threaded rod 19. Through the connection of the connecting plate 24, the mounting box 13 and the top plate 1 can be vertically raised and lowered, thereby realizing the height adjustment of round objects such as cigarettes held by the claw 10.

[0022] Please see Figure 4The front sides of the upright plate 17 are equipped with slide rails 22, and sliders 23 are slidably connected to the slide rails 22. The front ends of the two sliders 23 are fixedly connected to the connecting plate 24. Through the connecting action of the connecting plate 24 and the cooperation between the slide rails 22 and the sliders 23 on both sides of the upright plate 17, the nut seat 21 moves up and down along the threaded rod 19, which drives the sliders 23 to move synchronously along the slide rails 22. This provides guidance for the lifting process, ensures smooth movement, and effectively prevents the nut seat 21 from rotating during the up and down movement.

[0023] Please see Figure 2 and Figure 4 Multiple sets of reinforcing plates 25 are installed between the top of the rear end of the base plate 16 and the vertical plate 17. The multiple sets of reinforcing plates 25 installed between the top of the rear end of the base plate 16 and the vertical plate 17 can improve the stability of the bottom of the entire device, reduce shaking during operation, and enhance the overall support strength.
