Description

Technical Field

[0001] This utility model belongs to the field of palletizing equipment technology, specifically relating to a gripper for palletizing lithium salt barrels. Background Technology

[0002] In the lithium salt production industry, lithium salts are typically packaged in drums for further processing, making palletizing operations crucial for the storage and transportation of lithium salt products. The palletizing gripper, as the core component for grasping and handling lithium salt drums, directly impacts the efficiency of the palletizing process.

[0003] During the palletizing process, lithium salt drums need to be moved from one location to another for stacking. The existing grippers have a small contact area with the lithium salt drums, which cannot provide sufficient and uniform gripping force. This causes the lithium salt drums to wobble during transport or even slip off the grippers, posing a certain safety hazard. In addition, the gripping diameter of the existing grippers is fixed and cannot be adapted to lithium salt drums of different sizes.

[0004] Therefore, in order to solve the above problems, it is necessary to design a gripper for stacking lithium salt barrels. Utility Model Content

[0005] The purpose of this invention is to provide a gripper for stacking lithium salt barrels to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a gripper for stacking lithium salt barrels, comprising: The base plate and two aluminum profiles set on one side of the base plate; The pressing assembly includes: an electric cylinder disposed on the other side of the base plate and a first arc-shaped plate connected to the telescopic end of the electric cylinder; wherein... The electric cylinder is adapted to have its first arc-shaped plate abut against the lithium salt tank when extended; Two symmetrically arranged clamping assemblies, each comprising: a support plate connected to two aluminum profiles, a cylinder connected to the support plate, and at least two second arc-shaped plates connected to the telescopic ends of the cylinder; wherein... The two cylinders are adapted to move the corresponding second arc-shaped plates inward during retraction, so that each second arc-shaped plate and the first arc-shaped plate can grasp the lithium salt barrel.

[0007] Furthermore, the pressure-blocking component also includes: a first rubber pad disposed on the inner side of the first arc-shaped plate; The clamping assembly further includes: a second rubber pad disposed on the inner side of the second arc-shaped plate; wherein The first rubber pad and each of the second rubber pads are adapted to contact the lithium salt tank.

[0008] Furthermore, the clamping assembly further includes: two bearing seats disposed on one side of the support plate, a rotating shaft connected to the bearings of the two bearing seats, a connecting arm sleeved on the rotating shaft, a U-shaped piece rotatably connected to the other end of the connecting arm, and two trunnion seats disposed on the support plate; wherein Each of the second arc-shaped plates is connected to the rotating shaft; The support plate is provided with a clearance section; The connecting arm is located within the clearance section and can move within the clearance section; The other end of the U-shaped component is connected to the telescopic end of the cylinder. The cylinder is rotatably connected to the trunnion seat; and The cylinder is adapted to move the connecting arm within the clearance section via the U-shaped component during retraction. The connecting arm drives the rotating shaft to rotate, so that each second arc-shaped plate swings inward to grab the lithium salt bucket.

[0009] Furthermore, the clamping assembly further includes: swing arms sleeved at both ends of the rotating shaft and a connecting plate connected to the two swing arms; wherein Each of the second arc-shaped plates is connected to the connecting plate.

[0010] Furthermore, two buffer seats are provided on one side of the support plate; wherein The buffer seat is equipped with a buffer; and The buffer is adapted to contact the rotating swing arm.

[0011] Furthermore, a connecting frame is provided on the base plate; wherein The connecting frame is adapted to be connected to a palletizing robot.

[0012] The beneficial effects of this utility model are: (I) When the lithium salt drum needs to be gripped, the electric cylinder extends to push the first arc plate against one side of the lithium salt drum. Simultaneously, the two cylinders retract, causing the corresponding second arc plates to move inward. This allows each second arc plate and the first arc plate to grip the lithium salt drum from different directions, firmly clamping it in the middle. When the lithium salt drum needs to be placed, the electric cylinder retracts, and the two cylinders extend, separating the first and second arc plates from the lithium salt drum. The design of the first arc plate and multiple second arc plates significantly increases the contact area with the lithium salt drum, providing a more uniform and powerful gripping force. This effectively avoids the shaking or even slippage of the lithium salt drum during transport due to insufficient gripping force, improving the safety of palletizing operations. The extension and retraction control of the electric and cylinders allows adjustment of the positions of the first and second arc plates, enabling gripping of lithium salt drums of different diameters. This improves the versatility and adaptability of the gripper, meeting the palletizing needs of lithium salt drums of different specifications in the lithium salt production industry.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions 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 protection scope of this utility model. Example 1

[0019] like Figures 1 to 5 As shown, this embodiment provides a gripper for stacking lithium salt drums, including: A base plate 1 and two aluminum profiles 2 disposed on one side of the base plate 1; a pressing assembly 3, comprising: an electric cylinder 301 disposed on the other side of the base plate 1 and a first arc-shaped plate 302 connected to the telescopic end of the electric cylinder 301; wherein the electric cylinder 301 is adapted to abut the first arc-shaped plate 302 against the lithium salt container when extended; two symmetrically arranged clamping assemblies 4, comprising: a support plate 401 connected to the two aluminum profiles 2, a cylinder 402 connected to the support plate 401, and at least two second arc-shaped plates 403 connected to the telescopic end of the cylinder 402; wherein the two cylinders 402 are adapted to drive the corresponding second arc-shaped plates 403 to move inward when retracted, so that each second arc-shaped plate 403 moves inward. Plate 403 and the first arc-shaped plate 302 grip the lithium salt container; the aluminum material 2 is preferably made of lightweight and high-strength aluminum to reduce the overall weight of the gripper (reduce the load on the palletizing robot and improve operational flexibility) while ensuring the connection strength between the base plate 1 and the support plate 401 to meet the force requirements when gripping the lithium salt container; the arc design of the first arc-shaped plate 302 and the second arc-shaped plate 403 better fits the shape of the lithium salt container and increases the contact area with the lithium salt container; the first arc-shaped plate 302 and the two sets of second arc-shaped plates 403 are preferably arranged in a triangle to facilitate gripping the lithium salt container from different directions.

[0020] In this embodiment, when it is necessary to grasp the lithium salt container, the electric cylinder 301 is extended, pushing the first arc-shaped plate 302 to abut against one side of the lithium salt container. Simultaneously, the two cylinders 402 retract, causing the corresponding second arc-shaped plates 403 to move inward. This allows the second arc-shaped plates 403 and the first arc-shaped plate 302 to grasp the lithium salt container from different directions, firmly clamping it in the middle. When it is necessary to place the lithium salt container, the electric cylinder 301 retracts, and the two cylinders 402 extend, separating the first arc-shaped plate 302 and the second arc-shaped plate 403 from the lithium salt container. The first arc-shaped plate 302 then... The design of the first arc plate 302 and the second arc plate 403 greatly increases the contact area with the lithium salt drum, providing a more uniform and stronger gripping force. This effectively avoids the shaking or even slippage of the lithium salt drum during transportation due to insufficient gripping force, thus improving the safety of the palletizing operation. Through the extension and retraction control of the electric cylinder 301 and the pneumatic cylinder 402, the position of the first arc plate 302 and the second arc plate 403 can be adjusted, thereby enabling the gripping of lithium salt drums of different diameters. This improves the versatility and adaptability of the gripper, meeting the palletizing needs of lithium salt drums of different specifications in the lithium salt production industry.

[0021] The pressing component 3 further includes a first rubber pad 303 disposed on the inner side of the first arc-shaped plate 302; the clamping component 4 further includes a second rubber pad 404 disposed on the inner side of the second arc-shaped plate 403; wherein the first rubber pad 303 and each of the second rubber pads 404 are adapted to contact the lithium salt container; wherein by providing the first rubber pad 303 and the second rubber pad 404, the clamping friction is enhanced to prevent the container from slipping, while buffering the clamping force to avoid physical damage to the container caused by the first arc-shaped plate 302 and the second arc-shaped plate.

[0022] The clamping assembly 4 further includes: two bearing seats 405 disposed on one side of the support plate 401, a rotating shaft 406 connected to the bearings of the two bearing seats 405, a connecting arm 407 sleeved on the rotating shaft 406, a U-shaped member 408 rotatably connected to the other end of the connecting arm 407, and two trunnion seats 409 disposed on the support plate 401; wherein each of the second arc-shaped plates 403 is connected to the rotating shaft 406; the support plate 401 is provided with a clearance portion 4011; the connecting arm 407 is located within the clearance portion 4011 and moves within the clearance portion 4011; the other end of the U-shaped member 408 is connected to the telescopic end of the cylinder 402; the cylinder 402 is rotatably connected to the trunnion seat 409; and the cylinder 402 is adapted to pass through the U-shaped member 408 during retraction. The connecting arm 407 moves within the clearance portion 4011, and the connecting arm 407 drives the rotating shaft 406 to rotate, so that each of the second arc-shaped plates 403 swings inward to grab the lithium salt bucket. A bearing seat 405 is provided to provide stable support and a rotating bearing connection for the rotating shaft 406, ensuring smooth rotation of the shaft 406. The connecting arm 407, driven by the U-shaped member 408, moves within the clearance portion 4011 of the support plate 401, thereby converting the linear motion of the U-shaped member 408 into the rotational motion of the rotating shaft 406. Since the movement trajectory of the connecting arm 407 is oscillating, a cylinder 402 is rotatably connected to the trunnion seat 409, and the connecting arm 407 is rotatably connected to the U-shaped member 408 to adapt to the movement trajectory of the connecting arm 407.

[0023] The clamping assembly 4 further includes: swing arms 410 sleeved on both ends of the rotating shaft 406 and connecting plates 411 connected to the two swing arms 410; wherein each of the second arc-shaped plates 403 is connected to the connecting plates 411; wherein the swing arms 410 are provided to increase the clamping range of the second arc-shaped plates 403; wherein the connecting plates 411 are provided to ensure the connection stability of the second arc-shaped plates 403.
