Description

Technical Field

[0001] This utility model relates to the field of industrial sorting robot technology, specifically to an industrial sorting robot with adjustable axis spacing. Background Technology

[0002] In modern industrial production, industrial sorting robots are widely used in logistics warehousing, food processing, electronics manufacturing, and other industries, undertaking the important task of quickly and accurately sorting items of different specifications. With the expansion of production scale and the increasing variety of products, higher requirements are placed on the flexibility and adaptability of sorting robots.

[0003] Most existing industrial sorting robots have a fixed axis spacing, which means they can only sort items within a specific size range. When they encounter items of different sizes, they either cannot grasp them or the gripping is unstable due to the unsuitable axis spacing, which can easily lead to items falling or being damaged, seriously affecting sorting efficiency and quality. For example, in logistics warehouses, packages vary in size, and robots with a fixed axis spacing have difficulty handling both small express parcels and large packaging boxes. Utility Model Content

[0004] In view of the problems existing in the current industrial sorting robots, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an industrial sorting robot with adjustable axis spacing, which solves the problem that most existing industrial sorting robots have fixed axis spacing and can only sort items within a specific size range. When encountering items of different sizes, they either cannot be gripped or the gripping is unstable due to unsuitable axis spacing, which easily leads to items falling or being damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An industrial sorting robot with adjustable axis spacing includes a base with a cavity inside. Through holes are formed at both ends of the cavity, and movable rods are slidably disposed inside each of the through holes. A drive mechanism is disposed inside the cavity, and the two movable rods move via the drive mechanism. A movable plate is fixedly connected to one end of each of the two movable rods. Grippers are attached to the lower surfaces of the two movable plates. An adjustment mechanism is provided between each gripper and its corresponding movable plate, and the two grippers rotate via their respective adjustment mechanisms.

[0008] Preferably, the driving mechanism includes a motor, a rotating rod, a gear, two racks, and two fixed plates. The rotating rod is rotatably connected to the inside of the cavity. The gear is fixedly sleeved on the rod wall. The two fixed plates are respectively fixedly connected to one end of the corresponding moving rod. The two racks are respectively fixedly connected to one side of the corresponding fixed plate. Both racks mesh with the gear. The motor is fixedly connected to the upper surface of the base. The upper end of the rotating rod penetrates the upper surface inside the cavity and is fixedly connected to the output end of the motor.

[0009] Preferably, the adjustment mechanism includes two first mounting plates, two cylinders, two U-shaped rods, two sliders, and two second mounting plates. The two first mounting plates are respectively fixedly connected to one side of the corresponding moving plate. The two cylinders are respectively fixedly connected to the lower surface of the corresponding first mounting plate. The two second mounting plates are respectively fixedly connected to one side of the corresponding gripper. The two U-shaped rods are respectively fixedly connected to the upper surface of the corresponding second mounting plate. The two sliders are respectively slidably sleeved on the outer surface of the corresponding U-shaped rod. The output ends of the two cylinders are respectively hinged to the upper surface of the corresponding slider.

[0010] Preferably, the inner wall of the cavity is symmetrically provided with limiting grooves, and two limiting blocks are slidably arranged inside each of the two limiting grooves. The two corresponding limiting blocks are respectively fixedly connected to one side of the corresponding rack.

[0011] Preferably, two L-shaped plates are fixedly connected to the upper surface of the base, and each of the two L-shaped plates has a mounting hole on its upper surface, and bolts are fixedly connected inside each of the two mounting holes.

[0012] Preferably, each of the two grippers has a plurality of anti-slip protrusions fixedly connected to one side.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, through the transmission of motor, gear and rack, can quickly expand or reduce the axial distance between the two grippers, accurately match items of different sizes, such as small packages and large packaging boxes, without changing equipment or adjusting the mechanical structure, and can achieve stable gripping of items of various specifications, significantly improving the flexibility and applicability of sorting robots, and solving the limitations of traditional fixed axial distance robots.

[0015] 2. This utility model uses a cylinder to drive a slider to slide on a U-shaped rod, which in turn drives the gripper to rotate around the hinge point, dynamically adjusting the gripper angle. Whether it's a flat item or an irregularly shaped workpiece, the gripper can conform to the surface of the item. Anti-slip protrusions increase friction, ensuring stability during gripping and reducing the risk of items falling or being damaged. It is especially suitable for sorting complex items with irregular surfaces. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses an industrial sorting robot with adjustable shaft spacing.

[0024] This utility model provides, for example Figure 1-3 The industrial sorting robot with adjustable axis spacing shown includes a base 1. The base 1 has a cavity inside, and through holes are opened at both ends of the cavity. Movable rods 2 are slidably arranged inside the two through holes. A drive mechanism is arranged inside the cavity. Both movable rods 2 move through the drive mechanism. One end of each movable rod 2 is fixedly connected to a movable plate 3. Grippers 4 are connected to the lower surfaces of the two movable plates 3. An adjustment mechanism is arranged between each gripper 4 and the corresponding movable plate 3. The two grippers 4 rotate through the corresponding adjustment mechanism.

[0025] In order for the two movable levers 2 to be movable, as follows: Figure 1-2As shown, the drive mechanism includes a motor 5, a rotating rod 6, a gear 7, two racks 8, and two fixed plates 9. The rotating rod 6 is rotatably connected to the inside of the cavity. The gear 7 is fixedly sleeved on the rod wall of the rotating rod 6. The two fixed plates 9 are respectively fixedly connected to one end of the corresponding moving rod 2. The two racks 8 are respectively fixedly connected to one side of the corresponding fixed plate 9. Both racks 8 mesh with the gear 7. The motor 5 is fixedly connected to the upper surface of the base 1. The upper end of the rotating rod 6 penetrates the upper surface inside the cavity and is fixedly connected to the output end of the motor 5.

[0026] When the motor 5 is started, its output end drives the rotating rod 6 and the gear 7 to rotate. Since the two racks 8 mesh with the gear 7 respectively and in opposite directions, when the gear 7 rotates clockwise, the left rack 8 moves to the left and the right rack 8 moves to the right. Through the fixed plate 9, the moving rod 2 and the moving plate 3 move in opposite directions, thereby increasing the axial distance between the two grippers 4. Conversely, when the gear rotates counterclockwise, the axial distance decreases.

[0027] To make gripper 4 rotate, as Figure 1-3 As shown, the adjustment mechanism includes two first mounting plates 10, two cylinders 11, two U-shaped rods 12, two sliders 13, and two second mounting plates 14. The two first mounting plates 10 are respectively fixedly connected to one side of the corresponding moving plate 3. The two cylinders 11 are respectively fixedly connected to the lower surface of the corresponding first mounting plate 10. The two second mounting plates 14 are respectively fixedly connected to one side of the corresponding gripper 4. The two U-shaped rods 12 are respectively fixedly connected to the upper surface of the corresponding second mounting plate 14. The two sliders 13 are respectively slidably sleeved on the outer surface of the corresponding U-shaped rod 12. The output ends of the two cylinders 11 are respectively hinged to the upper surface of the corresponding slider 13.

[0028] After cylinder 11 is started, its output end pushes slider 13 to slide on U-shaped rod 12. Since slider 13 and gripper 4 are hinged through second mounting plate 14, the movement of slider causes gripper to rotate around hinge point. For example, when cylinder extends, slider moves upward and gripper 4 flips outward; when cylinder retracts, gripper flips inward, realizing dynamic adjustment of gripper angle.

[0029] To make the moving lever 2 more stable, such as Figure 1-2 As shown, symmetrical limit grooves are formed on the inner wall of the cavity, and two limit blocks 15 are slidably arranged inside each of the two limit grooves. The two limit blocks 15 are respectively fixedly connected to one side of the corresponding rack 8.

[0030] The limiting blocks 15 on both sides of the rack 8 slide in the limiting groove to ensure that the moving rod 2 moves smoothly along a straight line, avoids shaking, and ensures the accuracy and stability of the shaft spacing adjustment.

[0031] To facilitate the installation of this device, such as Figure 1As shown, two L-shaped plates 16 are fixedly connected to the upper surface of the base 1. The upper surface of the two L-shaped plates 16 is provided with mounting holes, and bolts 17 are fixedly connected inside the two mounting holes.

[0032] The robotic arm is fixed to the sorting equipment or production line by L-shaped plate 16 and bolts 17.

[0033] To make the gripping more stable, such as Figure 1 As shown, multiple anti-slip protrusions 18 are fixedly connected to one side of each of the two grippers 4.

[0034] The anti-slip protrusions 18 on the gripper 4 increase the friction with the item, so that even after the axis spacing is slightly adjusted, it can reliably grip items with different surface materials and reduce the risk of slipping.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
