Description

Technical Field

[0001] The utility model belongs to the technical field of automobile lithium battery production, and specifically relates to a piece-picking mechanical arm clamp for loading and unloading automobile lithium battery production. Background Art

[0002] In the production process of automotive lithium batteries, loading and unloading operations are crucial to improving production efficiency and ensuring product quality. At present, there are some problems in the actual application of existing robotic arm grippers used for loading and unloading of automotive lithium batteries. Traditional grippers often face the problem of insufficient clamping force, which makes it easy for them to slip when clamping lithium batteries, especially for some heavier or smoother lithium batteries. This will not only affect the continuity of production, but may also cause damage to the lithium batteries and increase production costs.

[0003] In the prior art, the application number is CN202220048440.4, and the name is a casting robot picking-up mechanical arm gripper, which discloses a casting robot picking-up mechanical arm gripper, including a clamping frame and an electric push rod, wherein two electric push rods are provided, and the two electric push rods are horizontally installed on the two side surfaces of the clamping frame, the protruding end of the electric push rod passes through the inner side of the clamping frame, and the end of the electric push rod is vertically fixed with a clamping block, and the inner surface of the clamping block is installed with a clamping plate through a hinge, and the hinge is connected above between the clamping block and the clamping plate.

[0004] Although the above patent uses the method of pulling the block up by the sling to make the block resist against the clamping plate more strongly as the upward pulling force on the block increases, so that the raw materials are clamped tighter to avoid slipping when clamping the raw materials, but since the two ends of the sling are respectively connected to the block and the cross plate, and the sling is also in a straightened state in the initial state, as long as the electric telescopic rod pushes the clamping block to move, the block will move upward under the pull of the sling, thereby causing the clamping plate to tilt, so that when the clamping plate moves to be in contact with the side wall of the material, only the lower end of the clamping plate is in contact with the material, reducing the contact area between the clamping plate and the material, thereby affecting the reliability of clamping and moving the material. In view of this, the present utility model is specially proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a robotic arm gripper for loading and unloading automotive lithium battery production that can overcome the above problems or at least partially solve the above problems.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0021] Example 1:

[0022] Reference Figure 1-Figure 4A robotic arm gripper for loading and unloading materials in the production of automotive lithium batteries, comprising a clamping frame 1, which is mounted on the end of the robotic arm by fixing bolts, and further comprising: movable plates 3, symmetrically arranged on both sides of the inner portion of the clamping frame 1; a clamping plate 4, rotatably connected to the sides of the two movable plates 3 close to each other via a rotating shaft; an electric telescopic rod 2, symmetrically arranged on both sides of the clamping frame 1, and both movable plates 3 are connected to the telescopic end of the electric telescopic rod 2 on the same side via a connecting assembly; a groove 304 is provided on the lower side of the movable plate 3 close to the clamping plate 4; a stop block 5, arranged in the groove 304, stops The two sides of the block 5 are respectively slidably attached to the groove wall of the groove 304 and the side wall of the clamping plate 4, and the side of the block 5 attached to the groove 304 is provided with inclined surfaces that cooperate with each other; the upper end of the inner part of the clamping frame 1 is provided with a first T-shaped slide groove 101, and two first T-shaped blocks 102 are symmetrically slidably connected in the first T-shaped slide groove 101; a through groove 305 is provided in the movable plate 3, and a connecting rod 501 is provided in the through groove 305. The upper and lower sides of the connecting rod 501 are respectively fixedly connected to the first T-shaped block 102 and the block 5 on the same side, and the width of the through groove 305 is greater than the width of the connecting rod 501.

[0023] The connecting assembly includes a second T-shaped block 302 and a tensioning spring 303. A second T-shaped slot 301 is provided at a position of the movable plate 3 close to the electric telescopic rod 2 on the same side. The second T-shaped block 302 is slidably connected to the second T-shaped slot 301. The tensioning spring 303 is arranged in the second T-shaped slot 301. The two ends of the tensioning spring 303 are fixedly connected to the second T-shaped block 302 and the upper end surface of the second T-shaped slot 301, respectively.

[0024] When the battery pack is assembled and placed in the battery shell for packaging, the staff can use the mechanical arm to move the clamping frame 1 to the top of the lithium battery pack and make the two clamping plates 4 located on both sides of the lithium battery pack. Then the electric telescopic rod 2 can be started, and the electric telescopic rod 2 will drive the clamping plates 4 to move closer to the lithium battery pack through the moving plate 3 until the clamping plates 4 are tightly attached to the side walls of the lithium battery pack. Then the mechanical arm can clamp the lithium battery pack through the clamping claw. When the clamping claw clamps the lithium battery pack, the moving plate 3 will overcome the tensioning force of the tensioning spring 303 and move downward under the action of the gravity of the lithium battery pack. Then the push block 5 will move to one side of the clamping plate 4 under the push of the inclined surface of the moving plate 3. Then the push block 5 will generate a thrust on the clamping plate 4, thereby increasing the holding force of the lower end of the clamping plate 4 on the lithium battery pack. When the clamped lithium battery pack is heavy, the clamping plate 4 will A greater clamping force is applied to the lithium battery pack to ensure stable clamping and movement of the lithium battery, avoid the risk of the lithium battery falling due to insufficient clamping force, and effectively improve the adaptability and reliability of the clamp. Through the coordinated use of components such as the first T-shaped slide 101, the first T-shaped block 102, the connecting rod 501, the through groove 305 and the connecting assembly, compared with the method of using a sling to pull the block 5 in the prior art, when the lithium battery pack is clamped, not only can the clamping force be automatically adjusted according to the weight of the lithium battery pack to ensure the stability of the lithium battery pack clamping, but when the moving plate 3 moves toward the material, the problem of the block 5 moving upward due to the pull of the sling can also be avoided, thereby ensuring that the clamping plate 4 does not rotate when it contacts the material, ensuring the contact area between the clamping plate 4 and the lithium battery pack, and further ensuring the reliability of the lithium battery pack clamping.

[0025] Example 2:

[0026] Reference Figure 1-Figure 4 A picking robot arm clamp for loading and unloading materials in the production of automotive lithium batteries is basically the same as Example 1, and further: the electric telescopic rod 2 is symmetrically fixedly connected to one side of the clamping frame 1, and the stop block 5 is symmetrically arranged in the groove 304. By symmetrically arranging two electric telescopic rods 2 on both sides of the clamping frame 1, the stability of the moving plate 3 can be ensured. By symmetrically arranging two stop blocks 5 in the groove 304, the stability of the clamping plate 4 can be ensured when the stop block 5 moves against the clamping plate 4.

[0027] The surfaces of the first T-block 102, the second T-block 302, the retaining block 5 and the connecting rod 501 are all smooth. By smoothing the surfaces of the first T-block 102, the second T-block 302, the retaining block 5 and the connecting rod 501, the friction between the first T-block 102, the second T-block 302, the retaining block 5 and the connecting rod 501 and the movable plate 3 can be reduced, thereby facilitating the movable plate 3 to move downward under the action of the gravity of the lithium battery pack, and enabling the first T-block 102, the second T-block 302, the retaining block 5 and the connecting rod 501 to move more smoothly.

[0028] Example 3:

[0029] Reference Figure 1-Figure 4 , a picking robot arm clamp for loading and unloading materials in automobile lithium battery production is basically the same as Example 2, but further: a rubber friction pad 401 is fixedly connected to the side of the clamping plate 4 away from the movable plate 3. Through the arrangement of the rubber friction pad 401, when the clamping plate 4 is in contact with the lithium battery pack, not only can the friction between the clamping plate 4 and the lithium battery pack be increased to ensure the stability of the clamping of the lithium battery pack, but the clamping force of the clamping plate 4 on the lithium battery pack can also be greater, without causing clamping damage to the lithium battery pack, thereby effectively improving the protection effect of the lithium battery.

[0030] A rangefinder 6 is fixedly connected to one of the movable plates 3, and the detection end of the rangefinder 6 faces the other movable plate 3. The rangefinder 6 is located above the clamping plate 4. Through the setting of the rangefinder 6, the distance between the two clamping plates 4 can be monitored in real time, so that the moving distance of the clamping plate 4 can be flexibly controlled according to the specifications of the lithium battery, effectively improving the applicability of the clamp.

[0031] It should be noted that when the rangefinder 6 detects, the rangefinder 6 will transmit the detected data to the controller in real time. When the controller knows that the two clamping plates 4 have moved to the fixed position according to the specifications of the lithium battery, that is, the clamping plates 4 are tightly attached to the lithium battery pack, the electric telescopic rod 2 can be controlled to stop moving.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
