Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and processing, in particular to a lithium battery clamping device with a protective structure. Background Art

[0002] Lithium-ion batteries are a type of secondary battery (rechargeable battery) that relies primarily on the movement of lithium ions between the positive and negative electrodes to work. The production and processing of lithium batteries involves multiple steps, such as assembly. Different processing is performed between each step, so the lithium batteries need to be clamped and transported, and moved to different working machines for different processing. In automated production, factories use handling robots to perform clamping and transportation work to save manpower.

[0003] For example, the public document with application number 202023128022.6 discloses a lithium battery transport clamping device, which is driven by a universal wheel to move the device, and at the same time, the universal wheel is used to squeeze the hinged plate. When the hinged plate is squeezed, the telescopic rod is driven to squeeze the slider, and at the same time, the slider is used to squeeze the first spring, so that the device can better reduce shock and protect the device when in use. However, the lithium battery clamping device is manually pushed and transported during transportation. Compared with the automated manipulator, its efficiency is low, and it is difficult to maintain long-term high-intensity continuous work, and it is more manpower-consuming. Compared with the automatic clamping and conveying equipment of the same manipulator type, it mainly provides driving force on both sides for direct clamping, and directly and hard squeezes the lithium battery workpiece, which is easy to cause damage to the workpiece, and the bottom is suspended. If shaking occurs during transportation and the clamping claws are slightly loose, it may cause the lithium battery workpiece to fall off, and the protection and clamping stability of the lithium battery are poor.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a lithium battery clamping device with a protective structure is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a lithium battery clamping device with a protective structure to solve the problems raised in the above background technology.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a lithium battery clamping device with a protective structure comprises a clamping plate 1, two clamping plates 1 are symmetrically arranged on the left and right, a through cavity 2 is opened on the opposite side of the outer surface of the clamping plate 1, a movable plate 3 is rotatably arranged inside the groove body at the lower end of the clamping plate 1, a push handle 4 is fixedly installed on the top of the movable plate 3, a pushing rod 5 is arranged on the middle side of the push handle 4 close to the middle of the clamping plates 1 on both sides, a connecting rod 6 is fixedly installed on the upper side of the pushing rod 5 close to the middle side of the clamping plates 1 on both sides, a rubber soft plate 8 is fixedly arranged on the opposite end of the connecting rod 6 slidingly passing through the clamping plate 1, a thrust spring 7 is fixedly installed on the surface of the rubber soft plate 8 close to the side of the clamping plate 1, and the thrust spring 7 is sleeved on the outside of the connecting rod 6, and the end of the thrust spring 7 away from the rubber soft plate 8 is fixedly connected to the clamping plate 1, and the movable plate 3 and the push handle 4 are set to an inclined plane with the same slope, and the push handle 4 is located inside the splint 1 and is located on the same horizontal line as the through cavity 2. An assembly box 9 is arranged above the splint 1, and a bidirectional screw 10 is rotatably arranged in the middle of the inner surface of the assembly box 9 through a bearing, and the right end of the bidirectional screw 10 penetrates the assembly box 9 and is provided with a drive motor 12, and the drive motor 12 is fixedly connected to the right side of the outer surface of the assembly box 9, and through grooves 11 are provided on both sides of the bottom of the inner surface of the assembly box 9, and moving blocks 13 are threadedly connected at both ends of the surface of the bidirectional screw 10, and the lower end of the moving block 13 is fitted on the inner surface of the through groove 11 to slide and penetrate the through groove 11, and the bottom ends of the moving block 13 penetrating the through groove 11 are respectively fixedly connected to the top ends of the left and right splints 1.

[0021] Furthermore, a portion of the bottom end of the moving block 13 is located inside the through groove 11 and slides in contact therewith. When the bidirectional screw 10 rotates, the through groove 11 limits the moving block 13, so that the moving block 13 cannot rotate with the bidirectional screw 10 and can only move in the opposite or reverse direction under the pushing force of the thread to control the clamping or loosening of the splint 1.

[0022] Furthermore, when the clamping plate 1 is clamping, the rubber soft plate 8 contacts the lithium battery workpiece first, which increases the friction force while preventing the hard clamping plate 1 from scratching the lithium battery.

[0023] Furthermore, when the rubber soft plate 8 clamps the battery workpiece, it will also squeeze the thrust spring 7. The reverse thrust generated by the compression of the thrust spring 7 enables the rubber soft plate 8 to have the force to move toward the middle, thereby being able to pre-clamp the lithium battery workpiece. As the compression amount of the thrust spring 7 increases, the flexible clamping force formed by the thrust spring 7 becomes greater. The clamping plate 1 does not need to be close to the battery workpiece, and the battery workpiece can be stably clamped, thereby avoiding damage to the lithium battery caused by excessive clamping force.

[0024] Furthermore, while squeezing the thrust spring 7, the rubber soft plate 8 also drives the connecting rod 6 to contract and enter the interior of the splint 1, so that the pushing rod 5 moves to both sides, and uses the inclined surface to push the push handle 4 to gradually rotate toward the outside of the through cavity 2, so that the lower end of the movable plate 3 rotates and tilts up, protruding from the middle of the splints 1 on both sides. The lithium battery can be lifted up by pushing the inclined surface toward the middle, forming a limit stop under the lithium battery workpiece to prevent the lithium battery from sliding from the bottom, thereby improving the stability during clamping and transportation.

[0025] Furthermore, the greater the downward force of the lithium battery, the greater the force with which the movable plate 3 pushes the push handle 4 in the opposite direction, the push handle 4 pushes the pushing rod 5 in the opposite direction, and the pushing rod 5 pushes the connecting rod 6 and the rubber soft plate 8 in the opposite direction toward the middle, that is, the greater the clamping force on the lithium battery on the left and right sides, thereby making the lithium battery more firmly clamped.

[0026] Working principle: When using the lithium battery clamping device with a protective structure, first, after aligning the lithium battery workpiece, use the driving motor 12 to drive the bidirectional screw 10 to rotate, and under the limit of the moving block 13 by the through slot 11, the moving block 13 can be moved in the opposite direction, driving the clamping plate 1 to clamp the lithium battery. When the clamping plate 1 is clamping, the rubber soft plate 8 first contacts the lithium battery workpiece, increasing the friction while preventing the hard clamping plate 1 from scratching the lithium battery. As the clamping plate 1 continues to move in the opposite direction to clamp, the rubber soft plate 8 will squeeze the thrust spring 7 to both sides to contract, and at the same time, it will also drive the connecting rod 6 to converge and enter the clamping plate 1 The inside of the body is used to move the pushing rod 5 to both sides, and the push handle 4 is pushed by the inclined surface to gradually rotate toward the outside of the through cavity 2, so that the lower end of the movable plate 3 is rotated and tilted, protruding from the middle of the clamping plates 1 on both sides. The lithium battery can be lifted up by pushing the inclined surface toward the middle. The elastic force of the thrust spring 7 and the friction force of the rubber soft plate 8 can make the left and right sides of the lithium battery be subjected to a certain clamping force, and the movable plate 3 at the bottom is used to limit the lifting of the lithium battery below, so that the clamping device does not need to use excessive clamping force on both sides, and can stably clamp and lift the lithium battery for transportation. This is the working principle of the lithium battery clamping device with a protective structure.
