Description

Technical Field

[0001] This utility model relates to the field of battery handling equipment technology, specifically a clamping device for assisting a robotic arm in handling batteries. Background Technology

[0002] As the core energy storage component of a battery, the battery cell converts chemical energy into electrical energy, and its performance and structure have a decisive impact on the overall performance of the battery. The battery cell constitutes the "heart" of the battery, composed of key materials such as the positive electrode, negative electrode, separator, and electrolyte, and achieves charging and discharging functions through electrochemical reactions. Battery cells mainly come in three forms: cylindrical, prismatic, and pouch.

[0003] During the production process, after the battery cells are completed, multiple cells are typically stored in anti-static turnover baskets. These baskets then need to be moved to the conveyor line for the next step. This process relies on the collaboration of a robotic arm and operators. However, there is currently a lack of a suitable gripping device mounted on the robotic arm that can quickly and effectively grip the anti-static turnover baskets. Utility Model Content

[0004] This invention provides a clamping device for assisting robotic arms in handling batteries, thereby addressing the problem mentioned in the background art of the lack of a suitable clamping device for installation on assistive robotic arms that can quickly and effectively clamp anti-static turnover baskets.

[0005] To address the existing problems, this utility model provides a clamping device for assisting a robotic arm in handling batteries, including a fixed frame. Two lifting arms are fixedly connected to the upper surface of the fixed frame, and the two lifting arms are symmetrically distributed on the fixed frame. A bearing plate is fixedly connected inside the fixed frame, and two pressure plates are fixedly connected to the lower surface of the fixed frame. Two clamping components are symmetrically arranged on the lower surface of the bearing plate, and a driving component is provided on the bearing plate between the two clamping components.

[0006] The clamping assembly includes two slide rails fixedly connected to the lower surface of the support plate near the end. A slider is slidably connected to the slide rail. The bottom end of the slider is fixedly connected to the connecting plate. A mounting plate is fixedly connected to the lower side of the connecting plate. Two fixing arms are vertically connected to the lower surface of the mounting plate. A clamping plate is fixedly connected to the side of the fixing arm near the drive assembly. Two limiting blocks are fixedly connected to the side of the clamping plate near the drive assembly.

[0007] The drive assembly includes a fixed shaft fixedly installed at the center of the lower surface of the support plate. A connecting arm is rotatably connected to the lower end of the fixed shaft. Both ends of the connecting arm are hinged to one end of a linkage arm. The other end of the linkage arm is hinged to the side end of a nearby connecting plate. An extension plate is fixedly connected to the upper surface of the connecting plate. The extension plate is fixedly connected to the telescopic end of an electric cylinder fixedly installed on the upper surface of the support plate.

[0008] Furthermore, fixing blocks are fixedly connected to the upper surfaces of the four corners of the fixing frame, and first lifting rings are fixedly installed on the fixing blocks.

[0009] Furthermore, a second lifting ring is fixedly installed on the middle upper surface of the boom.

[0010] Furthermore, the support plate is provided with a strip-shaped through groove for the extension plate to move.

[0011] Furthermore, the side of the fixed arm and the lower surface of the mounting plate are both fixedly connected to the side end of the reinforcing rib.

[0012] Furthermore, the pressure plate is located on the outside of the drive assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a clamping assembly and a driving assembly, works as follows: When the electric cylinder telescopic rod retracts, it drives the extension plate and its connected connecting plate to move towards the center of the support plate. The connecting plate pushes the linkage arm hinged to it, and the other end of the linkage arm drives the connecting arm hinged to it to rotate around a fixed axis. This, in turn, pulls the other linkage arm hinged to it, forcing the connecting plate of the other clamping assembly to move. Ultimately, the two sets of clamping assemblies slide towards each other, and then the limiting block engages with the through hole of the anti-static turnover basket to complete the clamping. When the electric cylinder telescopic rod extends, the extension plate moves in the opposite direction, and the connecting arm is pulled in the opposite direction by the linkage arm, driving the two sets of clamping assemblies to slide apart. The limiting block disengages from the through hole, releasing the turnover basket. This design achieves synchronous action of the two clamping assemblies through mechanical linkage, ensuring uniform distribution of clamping force. Furthermore, it relies on a single electric cylinder for control, simplifying the structure and improving operational reliability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A clamping device for assisting a robotic arm in handling batteries includes a fixed frame 1, two lifting arms 2 fixedly connected to the upper surface of the fixed frame 1, the two lifting arms 2 being symmetrically distributed on the fixed frame 1, a bearing plate 3 fixedly connected inside the fixed frame 1, two pressure plates 4 fixedly connected to the lower surface of the fixed frame 1, two clamping components 5 symmetrically arranged on the lower surface of the bearing plate 3, a drive component 6 located between the two clamping components 5 and provided on the bearing plate 3;

[0022] The clamping assembly 5 includes two slide rails 501 fixedly connected to the lower surface of the support plate 3 near the end. A slider 502 is slidably connected to the slide rails 501. The bottom end of the slider 502 is fixedly connected to the connecting plate 503. A mounting plate 504 is fixedly connected to the lower side of the connecting plate 503. Two fixing arms 505 are vertically connected to the lower surface of the mounting plate 504. A clamping plate 506 is fixedly connected to the side of the fixing arm 505 near the drive assembly 6. Two limiting blocks 507 are fixedly connected to the side of the clamping plate 506 near the drive assembly 6.

[0023] The drive assembly 6 includes a fixed shaft 601 fixedly installed at the center of the lower surface of the support plate 3. A connecting arm 602 is rotatably connected to the lower end of the fixed shaft 601. Both ends of the connecting arm 602 are hinged to one end of the linkage arm 603. The other end of the linkage arm 603 is hinged to the side end of the adjacent connecting plate 503. An extension plate 604 is fixedly connected to the upper surface of the connecting plate 503. The extension plate 604 is fixedly connected to the telescopic end of the electric cylinder 605 fixedly installed on the upper surface of the support plate 3.

[0024] Among them, fixing blocks 7 are fixedly connected to the upper surfaces of the four corners of the fixing frame 1, and the first lifting ring 8 is fixedly installed on the fixing blocks 7.

[0025] It should be noted that antistatic rubber layers are provided on the side of the clamping plate 506 near the drive assembly 6 and on the lower surface of the pressure plate 4.

[0026] The second lifting ring 9 is fixedly installed on the middle upper surface of the boom 2.

[0027] The support plate 3 has a strip groove 10 for the extension plate 604 to move.

[0028] The side of the fixed arm 505 and the lower surface of the mounting plate 504 are both fixedly connected to the side end of the reinforcing rib 11.

[0029] The pressure plate 4 is located on the outside of the drive assembly 6.

[0030] Working principle: When working, first connect one end of the iron chain or other rope to the first lifting ring 8 and the second lifting ring 9 firmly, and then fix the other end of the iron chain or rope to the hook of the assistive mechanical arm to ensure that the entire clamping device is in a horizontal state. Then, the operator controls the robotic arm to move the clamping device above the anti-static turnover basket, causing the robotic arm to move the clamping device downwards. At this time, the clamping component 5 is in its maximum opening state, and then the two limit blocks 507 are aligned with the through holes opened on both sides of the anti-static turnover basket. At this time, the pressure plate 4 is in contact with the upper end of the anti-static turnover basket. Then, the extension rod of the electric cylinder 605 is controlled to retract, and then the extension rod of the electric cylinder 605 will drive the extension plate 604 and the connecting plate 503 to move towards the middle of the bearing plate 3. At this time, the connecting plate 503 will simultaneously drive the mounting plate 504, the fixed arm 505, the clamping plate 506, and the limit block 507 to slide on the slide rail 501 along with the slider 502, locking the limit block 507 into the through holes opened on both sides of the anti-static turnover basket. Then the electric cylinder 605 stops moving, and the robotic arm can then lift the anti-static turnover basket containing the battery cells and transfer it to the conveyor line.

[0031] The operating principle of drive component 6 needs further explanation here: When the telescopic rod of electric cylinder 605 retracts, it drives the connecting plate 503, mounting plate 504, fixing arm 505, clamping plate 506, and limiting block 507 of one of the clamping components 5 via extension plate 604. As the slider 502 slides on slide rail 501, the connecting plate 503 pushes a linkage arm 603 hinged to its side end to move in the same direction. The end of linkage arm 603 away from connecting plate 503 pushes the end of connecting arm 602 connected to it, thus the linkage arm 602 will... Rotation of the fixed shaft 601 causes the other end of the connecting arm 602 to pull a hinged linkage arm 603 to move. The end of the pulled linkage arm 603 away from the connecting arm 602 simultaneously pulls the side end of the hinged connecting plate 503. As the connecting plate 503, mounting plate 504, fixed arm 505, clamping plate 506, and limiting block 507 of the other clamping assembly 5 slide along the slide rail 501 with the slider 502, the two clamping assemblies 6 move towards each other, thus achieving the clamping process of the anti-static turnover basket. Similarly, when the telescopic rod of the electric cylinder 605 extends, the two clamping assemblies 6 move away from each other, thus achieving the release process of the clamped anti-static turnover basket.
