Description

Technical Field

[0001] This utility model relates to the field of waste battery recycling technology, specifically to a cutting and conveying mechanism for waste battery cell cutting equipment. Background Technology

[0002] With the increasing use of lithium-ion batteries in electric vehicles in my country, the harmless recycling of these batteries has become a key issue of great concern to the government and an urgent problem for the industry. A single lithium-ion battery cell is constructed by winding or stacking layers of a positive electrode sheet (made by coating both sides of aluminum foil with positive electrode material), a plastic separator, and a negative electrode sheet (made by coating both sides of copper foil with negative electrode material) into a circular or square shape. These layers are then encapsulated in a battery casing with an appropriate amount of electrolyte (lithium hexafluorophosphate + organic solvent).

[0003] In existing waste battery cell cutting equipment, the first step in manually sorting waste battery cores is removing the cover and end plates of the old batteries. During this process, workers must manually move and secure the waste batteries to the milling machine, ensuring the electrodes always face upwards. Because waste batteries may have warped edges or leak electrolyte, workers are at risk of being scratched by the warped edges or burned by the electrolyte while manually securing the batteries. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting and conveying mechanism for waste battery cell cutting equipment, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0005] A cutting and conveying mechanism for a waste battery cell cutting device includes a conveyor cart, a vertical lifting mechanism, a horizontal pushing mechanism, a transfer platform, and a material handling robot.

The vertical lifting mechanism includes a lifting plate movably disposed in the waste battery chamber, and the lifting plate is used for stacking waste batteries. The horizontal pushing mechanism is disposed at the top of the drive chamber. The transfer platform is disposed between the conveyor cart and the waste battery cell cutting device. The material handling robot is disposed on the transfer platform.

[0006] The vertical lifting mechanism is used to lift the waste batteries stacked on the lifting plate to the top of the waste battery chamber in sequence, the horizontal pushing mechanism is used to push the waste batteries lifted to the top of the waste battery chamber to the transfer platform in sequence, and the material handling robot is used to transport the waste batteries pushed to the transfer platform to the waste battery cell cutting equipment in sequence.

The two end plates are fixedly connected to the end face of the lifting plate through the connecting rod. The connecting rod is respectively provided in the vertical sliding groove of the side wall of the waste battery compartment.

[0008] As a further embodiment of this utility model: the lateral pushing mechanism includes a lateral cylinder and a push plate, the lateral cylinder is fixedly disposed on the top of the drive chamber, and the push plate is fixedly connected to the telescopic end of the lateral cylinder.

[0009] As a further embodiment of this utility model: the lateral pushing mechanism further includes a force equalizing plate and connecting blocks, the force equalizing plate is fixedly connected to the telescopic end of the lateral cylinder in the middle, and several connecting blocks are uniformly fixedly connected between the force equalizing plate and the push plate.

[0010] As a further embodiment of this utility model: the waste battery chamber is also provided with insulating plates at intervals, the insulating plates separating adjacent waste batteries on the left and right.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses a palletizing machine to stack waste batteries layer by layer onto a lifting plate inside the waste battery compartment. Then, a transport cart containing the stacked waste batteries is moved to a pre-set position next to a transfer platform. A vertical lifting mechanism lifts the waste batteries stacked on the lifting plate sequentially to the top of the waste battery compartment, allowing the entire battery pack to move upwards while maintaining a fixed height for the top layer of individual batteries. A horizontal pushing mechanism then pushes the top layer of waste batteries from the top of the compartment onto the transfer platform.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-5 As shown, this utility model embodiment is a cutting and conveying mechanism for waste battery cell cutting equipment, including a conveying box 1, a vertical lifting mechanism 2, a horizontal pushing mechanism 3, a transfer table 4, and a material handling robot 5.

[0029] Please see Figure 2 As shown, the top of the conveyor 1 has an opening, and the interior of the conveyor 1 is divided into a drive chamber 12 and a waste battery chamber 13 by a partition 11. The vertical lifting mechanism 2 includes a lifting plate 21 movably installed in the waste battery chamber 13. Waste batteries 6 are stacked on the lifting plate 21, and a stacking machine can stack the waste batteries 6 layer by layer onto the lifting plate 21. The horizontal pushing mechanism 3 is located on the top of the drive chamber 12, and the transfer platform 4 is located between the conveyor 1 and the waste battery cell cutting equipment 7; the material handling robot 5 is located on the transfer platform 4.

[0030] During operation, the conveyor trolley 1, with stacked waste batteries 6, is moved to a pre-set position next to the transfer platform 4. The vertical lifting mechanism 2 lifts the waste batteries 6 stacked on the lifting plate 21 sequentially to the top of the waste battery chamber 13. The waste batteries 6 move upwards as a whole within the waste battery chamber 13, maintaining the topmost waste battery 6 at a fixed height.

[0031] The horizontal pushing mechanism 3 lifts the waste batteries 6 at the top of the waste battery chamber 13 and pushes them sequentially onto the transfer platform 4. Finally, the material handling robot 5 transports the waste batteries 6 pushed onto the transfer platform 4 to the waste battery cell cutting equipment 7. This cycle continues. With the cooperation of the vertical lifting mechanism 2, the horizontal pushing mechanism 3, and the material handling robot 5, the multi-layered waste batteries 6 stacked in the conveyor trolley 1 are transported one by one to the waste battery cell cutting equipment 7 for processing. The entire conveying process does not require manual intervention, avoiding the risk of workers being scratched by the battery edges or burned by the electrolyte when manually fixing the waste batteries 6. Workers' personal safety is guaranteed, and the conveying efficiency is also improved.

[0032] Please see Figure 5 As shown, the vertical lifting mechanism 2 also includes a vertical cylinder 22, an end plate 23, and a connecting rod 24. A vertical cylinder 22 is respectively installed at the bottom of each side of the waste battery compartment 13. The telescopic ends of both vertical cylinders 22 are fixedly connected to an end plate 23. The two end plates 23 are fixedly connected to the end face of the lifting plate 21 via connecting rods 24. Please refer to... Figure 3 As shown, the connecting rods 24 are respectively installed in the vertical grooves 18 on the side wall of the waste battery compartment 13.

[0033] In use, the two vertical cylinders 22 are started simultaneously to push the two end plates 23 to move synchronously. The two end plates 23 drive the lifting plate 21 to move up and down in the waste battery chamber 13 through the connecting rod 24, thereby lifting the multi-layer waste batteries 6 stacked on the lifting plate 21 layer by layer, so that the horizontal pushing mechanism 3 can push the top layer of waste batteries 6.

[0034] Please see Figure 2 As shown, the lateral pushing mechanism 3 includes a lateral cylinder 31 and a push plate 32. The lateral cylinder 31 is fixedly mounted on the top of the drive chamber 12, and the push plate 32 is fixedly connected to the telescopic end of the lateral cylinder 31. Furthermore, the lateral pushing mechanism 3 also includes a force equalizing plate 33 and connecting blocks 34. The force equalizing plate 33 is fixedly connected to the telescopic end of the lateral cylinder 31 in the middle, and several connecting blocks 34 are evenly fixedly connected between the force equalizing plate 33 and the push plate 32.

[0035] When in use, the horizontal cylinder 31 is activated to push the force equalizing plate 33 to move towards the waste battery chamber 13. The force equalizing plate 33 drives the push plate 32 to move synchronously through the connecting block 34. The push plate 32 pushes the uppermost waste battery 6 in the waste battery chamber 13 to the transfer platform 4, so that the material handling robot 5 can transfer the waste batteries 6 on the transfer platform 4 to the waste battery cell cutting equipment 7 in sequence.

[0036] Further, please refer to Figure 5As shown, in this embodiment, insulating plates 14 are also spaced apart inside the waste battery chamber 13. The insulating plates 14 separate adjacent waste batteries 6 on the left and right sides. A plurality of ball bearings 15 are installed on both side walls of the insulating plates 14 and the inner side wall of the waste battery chamber 13. The insulating plates 14 not only prevent adjacent waste batteries 6 from interfering with each other during transport, but also prevent adjacent waste batteries 6 from touching each other and causing a short circuit and fire. The ball bearings 15 prevent direct friction between the waste batteries 6 and the side walls of the insulating plates 14 and the inner side wall of the waste battery chamber 13 during the upward movement of the waste batteries.

[0037] Further, please refer to Figure 4 As shown, in this embodiment, the waste battery chamber 13 has a notch 16 on the top side away from the drive chamber 12. The height of the notch 16 is not less than the thickness of one waste battery 6. This arrangement ensures that only the top layer of waste batteries 6 is at the notch 16. When the lateral pushing mechanism 3 pushes the top layer of waste batteries 6 to move, the waste batteries 6 below will not be moved along with it.

[0038] Further, please refer to Figure 1 As shown, in this embodiment, a boxcar track 8 is also included. Slider blocks 17 are evenly arranged on the bottom of the conveyor boxcar 1. The conveyor boxcar 1 is slidably mounted on the boxcar track 8 via the sliders 17. The boxcar track 8 facilitates the movement of the conveyor boxcar 1, improving work efficiency. Additionally, a limiting groove 41 matching the number of waste batteries 6 can be provided on the top side of the transfer platform 4 near the waste battery chamber 13. When the lateral pushing mechanism 3 pushes the uppermost layer of waste batteries 6 to the transfer platform 4, each waste battery 6 moves into its corresponding limiting groove 41.

[0039] It is understandable that the vertical lifting mechanism 2, the horizontal pushing mechanism 3, and the material handling robot 5 can all be electrically connected through a controller, such as a PLC controller. Their operating parameters can be set through the PLC controller, making them more intelligent. This is existing technology and will not be elaborated on here.

[0040] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
