Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and particularly to a grasping mechanism for lithium battery processing. Background Art

[0002] A lithium battery is a highly efficient and rechargeable chemical power source, which is widely used in modern electronic devices, electric vehicles and energy storage systems. Its main structure consists of a positive electrode (such as lithium cobalt oxide), a negative electrode (such as graphite), an electrolyte (an organic solvent containing a lithium salt) and a separator. According to its type, it can be divided into: lithium cobalt oxide battery, lithium iron phosphate battery, ternary lithium battery, lithium titanate battery, etc.

[0003] In the production and processing of lithium batteries, it is necessary to drive the lithium batteries for transportation through operating equipment, and grasping equipment is required for transporting lithium batteries. Current lithium battery grasping equipment includes robotic arms, vacuum suction cup devices, pneumatic grippers / fingers, special battery cell grasping jigs, etc. During the process of grasping lithium batteries with a robotic arm, it is easy to cause damage to the surface of the lithium battery or make the lithium battery fall from the grasping equipment due to inaccurate grasping force, resulting in damage.

[0004] In the prior art, there is a grasping mechanism for lithium battery processing (publication number: CN219254930U), belonging to the technical field of lithium battery processing. It includes a bottom plate, an elevating mechanism is arranged above the bottom plate, an adjusting seat is arranged above the elevating mechanism, a screw rod is arranged inside the adjusting seat, a limiting slider is arranged on the surface of the screw rod, a fixing plate is arranged on one side of the limiting slider, a lifting cylinder is arranged below the fixing plate, a grasping assembly is arranged below the lifting cylinder, and a connecting assembly is arranged between the lifting cylinder and the grasping assembly. Although this grasping mechanism for lithium battery processing can buffer the clamping force on the lithium battery to avoid excessive clamping force on the lithium battery and cause damage, and the grasping assembly has a simple structure and low cost. By setting the connecting assembly, the device is convenient for disassembling and assembling the grasping assembly during use, improving the convenience of use.

[0005] However, in the actual use process, the grasping force on the lithium battery is controlled by a bidirectional threaded lead screw. This method is prone to deviation during long-term operation, resulting in too large or too small clamping force on the lithium battery, thereby affecting the transportation safety of the lithium battery. Summary of the Invention

[0006] Aiming at the problems existing in the background art, a grasping mechanism for lithium battery processing is proposed.

A fixed bracket 7 is installed on the mounting plate 1, and a rotating motor 8 is arranged on the fixed bracket 7. A rotating seat 4 is rotatably installed on the mounting plate 1. The output shaft of the rotating motor 8 drives the rotating seat 4 to rotate through a transmission assembly 6. The transmission assembly 6 is composed of a rotating rod, two belt pulleys, a transmission belt, and two transmission gears 9. The rotating rod is rotatably installed on the mounting plate 1. The two belt pulleys are respectively sleeved on the rotating rod and the output shaft of the rotating motor 8. The transmission belt is sleeved on the two belt pulleys. The two transmission gears 9 are respectively sleeved on the rotating rod and the rotating seat 4, and the two transmission gears 9 are meshed and connected. A clamping bracket 2 and a positioning strip 19 are slidably installed on the mounting plate 1. A chute is provided on the mounting plate 1. Both the clamping bracket 2 and the positioning strip 19 are in a state of sliding connection with the inner wall of the chute. An adjusting bracket 5 is arranged on the rotating seat 4. By means of the adjusting bracket 5, the clamping bracket 2 and the positioning strip 19 are respectively driven to move to complete the positioning and clamping of the lithium battery. The adjusting bracket 5 is composed of a connecting strip and a rotating strip. The rotating strip is rotatably installed on the rotating seat 4. The connecting strip is used to connect the rotating strip with the clamping bracket 2 and the positioning strip 19. The connecting strip and the rotating strip are in a rotating connection. When the rotating seat 4 rotates, the clamping bracket 2 and the positioning strip 19 are respectively pulled to move through the connecting strip and the rotating strip. Grooves are provided on both the clamping bracket 2 and the positioning strip 19, and rubber strips 18 are arranged in the grooves. One side of the rubber strip 18 extends out of the groove. When the clamping bracket 2 and the positioning strip 19 are squeezed, the rubber strip 18 contracts into the groove;

[0027] A shovel foot 3 is arranged on the clamping bracket 2. The shovel foot 3 is bolted to the clamping bracket 2, which facilitates the replacement of the shovel foot 3. One side of the shovel foot 3 is provided with an inclined surface, which is used to make the lithium battery move upward during the extrusion process of the lithium battery and make the top of the shovel foot 3 contact the bottom of the lithium battery. The top of the shovel foot 3 can provide support for the bottom of the lithium battery. A shovel strip 17 is arranged on the inclined surface of the shovel foot 3. The shovel strip 17 is composed of a triangle, and the inclination angle of the inclined upward surface of the shovel strip 17 is greater than the inclination of the inclined surface of the shovel foot 3. The shovel strip 17 is composed of a soft plastic strip.

[0028] A moving screw barrel 11 is slidably mounted on the mounting plate 1. A slide bar is mounted on the mounting plate 1, and a slide carriage is sleeved on the slide bar. The slide carriage is connected to the moving screw barrel 11 to ensure that the moving screw barrel 11 can move stably. An adjusting screw 10 is threadedly mounted in the moving screw barrel 11. The top end of the adjusting screw 10 is connected to the output shaft of the rotating motor 8. A push plate is mounted at the bottom of the moving screw barrel 11. A bottom plate 12 is arranged below the push plate. A compression spring 14 is arranged between the bottom plate 12 and the push plate to connect the bottom plate 12 and the push plate. During the clamping process of the lithium battery, the bottom plate 12 gives the lithium battery a downward thrust under the action of the compression spring 14, so that the lithium battery is in stable contact with the top of the shovel foot 3. A rubber disc is arranged at the bottom of the bottom plate 12. The settings of the rubber strip 18 and the rubber disc can both form a buffer during the contact with the lithium battery, avoid hard clamping of the lithium battery, and reduce the probability of damage to the lithium battery.

[0029] A folding air cylinder 13 is arranged between the bottom plate 12 and the push plate. An air duct 15 is arranged on the clamping frame 2. The air duct 15 is composed of a telescopic hose.

The connection between the air duct 15 and the shovel foot 3 can be connected by a joint, which is convenient for the subsequent replacement of the shovel foot 3, and is used to convey the air flow in the folding air cylinder 13 into the shovel foot 3. An air outlet hole 16 is opened on the shovel foot 3. The air outlet hole 16 is arranged obliquely downward. When the air flow is discharged through the air outlet hole 16 and contacts the lithium battery, it can provide an upward thrust to the bottom edge of the lithium battery, so that the bottom edge of the lithium battery is upturned, which is convenient for the shovel foot 3 to be inserted into the bottom of the lithium battery.

[0030] In this embodiment, during use, the mounting plate 1 is connected to an external transfer device for transferring the lithium battery after clamping the lithium battery. Specifically, the mounting plate 1 is moved above the lithium battery, and then the mounting plate 1 is pushed down so that the bottom of the shovel foot 3 is on the same plane as the bottom of the lithium battery. Subsequently, the rotating motor 8 can be started to drive the rotating seat 4 to rotate through the transmission assembly 6, and then the clamping frame 2 and the positioning strip 19 are respectively driven to move through the adjusting frame 5. During the movement of the clamping frame 2, one side of the shovel foot 3 will be inserted into the bottom of the lithium battery, so that the lithium battery moves upward and finally the bottom of the lithium battery contacts the top of the shovel foot 3. At this time, the clamping frame 2 and the positioning strip 19 also complete the clamping and fixing of the periphery of the lithium battery. During the upward movement of the lithium battery, its top contacts the bottom plate 12, and a downward thrust is given to the lithium battery under the action of the compression spring 14, and then it stably contacts the top of the shovel foot 3, so that the comprehensive protection of the lithium battery can be completed, and the transfer safety of the lithium battery can be guaranteed;

[0031] During the process of the lithium battery moving upward and pushing the bottom plate 12 upward, the folding air cylinder 13 will be compressed, and then the air flow in the folding air cylinder 13 will flow into the shovel foot 3 and be discharged through the air outlet 16 to act on the bottom edge of the lithium battery. Thus, an upward thrust can be provided to the bottom edge of the lithium battery, enabling the shovel foot 3 to better insert into the bottom of the lithium battery and reducing the probability of damaging the bottom edge of the lithium battery.

[0032] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
