Description

Technical Field

[0001] This utility model belongs to the field of lithium-ion battery technology, specifically relating to a sorting and fixing device for lithium battery production and processing. Background Technology

[0002] As a core power component of new energy commercial vehicles, lithium batteries have extremely high requirements for safety and efficiency in their production and processing. In the assembly process of lithium batteries, the cylindrical battery casing (usually made of metal materials such as aluminum or steel) needs to be assembled with the battery cells. One of the key steps is to flip the horizontal battery casing to a vertical position so that it can be fixed on the workbench for subsequent spot welding and battery cell implantation operations.

[0003] In existing technology, workers need to manually rotate each horizontally placed cylindrical battery casing by 90 degrees and place it on a workbench before assembling the battery cells. This manual operation method has obvious shortcomings: on the one hand, frequent manual rotation and positioning are time-consuming and labor-intensive, resulting in low production efficiency; on the other hand, it is difficult to ensure the consistency of manual operation, which may affect the assembly accuracy of the battery casing and battery cells, and thus affect the overall quality of the lithium battery.

[0007] The material box is fixed on the base and includes a bottom plate, two side plates and a rear baffle. The bottom plate is inclined, with the higher end connected to the side plates and the lower end forming the material box outlet.

[0008] The battery casing feeding mechanism includes a feeding motor, a tilting wheel, and a vertical plate. The vertical plate is fixed on the base. The feeding motor drives the tilting wheel to rotate. The tilting wheel has multiple U-shaped grooves around its circumference and a baffle plate below it. The U-shaped grooves correspond to the outlet of the material box.

[0009] The battery casing flipping mechanism includes a flipping block, an arc-shaped guide rail, and a pushing cylinder. The flipping block is provided with a feeding port and an S-shaped track. The pushing block of the pushing cylinder pushes the cylindrical battery casing from the feeding port into the S-shaped track, so that it changes from a horizontal state to a vertical state.

[0010] The battery casing conveyor belt is located at the end of the arc-shaped guide rail, and baffles are provided on both sides of it.

[0011] Preferably, the inclination angle of the base plate is 5°-15°, and the lower end is aligned with the U-shaped groove of the turning wheel.

[0012] Preferably, the depth of the U-shaped groove of the rotating wheel is 1 / 2 to 2 / 3 of the diameter of the cylindrical battery case, and it can accommodate only one battery case per rotation.

[0013] Preferably, the inner wall of the S-shaped track of the flipping block is a smooth curved surface, with its top end perpendicular to the feed inlet and its bottom end parallel to the feed inlet.

[0014] Preferably, the pusher end of the pusher cylinder is provided with a rubber buffer pad, and the contact surface with the cylindrical battery casing is an arc-shaped groove.

[0015] Preferably, the width of the arc-shaped guide rail matches the height of the cylindrical battery case, and its end is seamlessly connected to the baffle of the battery case conveyor belt.

[0018] Preferably, the rear baffle is height-adjustable and is fixed to the base with bolts to accommodate battery cases of different sizes.

[0019] Preferably, the base is provided with a shock-absorbing pad at the bottom, and each mechanism is detachably connected to the base via a modular bracket.

[0020] The beneficial effects of this utility model are as follows: This patent achieves automatic and orderly discharge of battery casings through the cooperation of the inclined bottom plate of the material box and the U-shaped groove of the flipping wheel, significantly reducing manual operation and improving production efficiency. The S-shaped track and pushing cylinder in the flipping mechanism work together to smoothly convert the horizontal battery casings to a vertical position, avoiding the risk of jamming or deformation.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0034] like Figure 1 As shown, a sorting and fixing device for lithium battery production and processing includes a material bin 1, a battery casing feeding mechanism 2, a battery casing flipping mechanism 3, a battery casing conveyor belt 4, and a base 5. The material bin is used to lay battery casings flat, allowing cylindrical battery casings to be arranged horizontally. The material bin includes a base plate 11, side plates 12, and a rear baffle 13. The base plate is fixed to the bottom between the two side plates, with one side higher than the other. The tilt angle of the base plate is 5°-15°, and the lower end is aligned with the U-shaped groove of the flipping wheel. The lower end is the material bin outlet, facilitating the falling of cylindrical battery casings from the higher to the lower position. The rear baffle is fixed to the base. One rear baffle, two side plates, and one base plate form a material bin. Furthermore, the height of the rear baffle is adjustable and fixed to the base with bolts to accommodate battery casings of different sizes. Furthermore, the bottom of the base is equipped with shock-absorbing pads, and each mechanism is detachably connected to the base via a modular bracket.

[0035] like Figure 3 As shown, the battery casing feeding mechanism is used to feed cylindrical battery casings from the hopper into the battery casing flipping mechanism. The battery casing feeding mechanism includes a feeding motor 21, a flipping wheel 22, and a vertical plate 23. The vertical plate is fixed on the base, and the feeding motor is fixed on one side of the vertical plate. Furthermore, an extension plate is provided between the vertical plate and the baffle, forming a guide channel with the baffle to ensure that the battery casings fall accurately into the flipping mechanism. The flipping wheel is located on the other side of the vertical plate and is connected to the output end of the feeding motor. Several U-shaped grooves 24 are provided around the flipping wheel. The U-shaped grooves are used to support the cylindrical battery casings. The depth of the U-shaped grooves on the flipping wheel is 1 / 2 to 2 / 3 of the diameter of the cylindrical battery casing, and it can accommodate only one battery casing per rotation. Below the tilting wheel is a first baffle 25, which is used to block the cylindrical battery casing. An extension plate (not shown in the figure) is fixed between the upright plate and the baffle. The cylindrical battery casing falls into the battery casing tilting mechanism below through the channel between the extension plate and the baffle. The tilting wheel is located below the material box outlet. Each time the tilting wheel rotates, a cylindrical battery casing falls into a U-shaped groove. The motor drives the tilting wheel to rotate. With each rotation, the cylindrical battery casing in the U-shaped groove below the tilting wheel will fall into the battery casing tilting mechanism below.

[0036] like Figure 3 and Figure 4As shown, the battery casing flipping mechanism 3 is used to turn a horizontally placed cylindrical battery casing into an vertical position. The battery casing flipping mechanism includes a flipping block 31, an arc-shaped guide rail 32, and a pushing cylinder 33. The width of the arc-shaped guide rail matches the height of the cylindrical battery casing, and its end is seamlessly connected to the baffle of the battery casing conveyor belt. The flipping block is fixed on the base. One end of the flipping block is provided with a feed port 34, and the side is provided with an S-shaped track 35. The inner wall of the S-shaped track of the flipping block is a smooth curved surface. Its top end is perpendicular to the feed port, and its bottom end is parallel to the feed port. The end of the S-shaped track is connected to the arc-shaped guide rail. The pushing cylinder is fixed to the outside of the base, and a pushing block 36 is fixed on the piston rod of the pushing cylinder, directly opposite the feed inlet. It pushes the cylindrical battery case, which is placed flat at the feed inlet, into the S-shaped track. With each push, the cylindrical battery case gradually changes its position within the S-shaped track, changing from a horizontal to a vertical position, and finally enters the arc-shaped guide rail connected to the outlet of the S-shaped track. Furthermore, the end of the pushing block of the pushing cylinder is provided with a rubber buffer pad, and the contact surface with the cylindrical battery case is an arc-shaped groove.

[0037] The battery case conveyor belt 4 is located at the end of the arc-shaped guide rail. A second baffle 41 is provided at the top of the conveyor belt. The conveyor belt is driven by a drive motor 42. The distance between the two baffles is the same as the width of the arc-shaped guide rail. Vertically positioned cylindrical battery cases exiting the arc-shaped guide rail enter the conveyor belt and are conveyed to a fixing mechanism on the worktable for assembly. Furthermore, the drive motor for the battery case conveyor belt is a stepper motor, and its rotational speed is synchronized with the operating frequency of the push cylinder.

[0038] This device achieves a fully automated process from sorting to fixing cylindrical battery casings through the coordinated operation of the material bin, battery casing feeding mechanism, flipping mechanism, and conveyor belt. The specific working process is as follows:

[0039] Battery casing 6 is placed flat in the hopper, and the inclined base plate uses gravity to slide the battery casing towards the lower outlet. The tilting wheel is driven by the feed motor to rotate at regular intervals. Its circumferentially distributed U-shaped grooves receive the battery casings sliding down from the hopper outlet one by one, and the baffle restricts the movement so that only a single battery casing can leave the tilting wheel. The guide channel formed by the extension plate and the baffle ensures that the battery casing falls accurately into the feed port of the tilting mechanism.

[0040] The pusher cylinder pushes the battery casing, which is placed flat at the feed inlet, into the S-shaped track of the tilting block. The inner wall of the S-shaped track is designed with a smooth curved surface. During the pushing process, the battery casing gradually transitions from a horizontal to a vertical state along the curved surface of the track, and finally slides into the arc-shaped guide rail. The pusher block end of the pusher cylinder is equipped with a buffer structure to prevent the battery casing from being deformed or damaged by the pushing impact.

[0041] The vertically positioned battery casings slide onto the conveyor belt via curved guide rails. The spacing between the baffles on both sides of the conveyor belt matches the height of the battery casings to prevent them from shifting or tipping over during transport. A stepper motor drives the conveyor belt to run at a constant speed, its rotational speed synchronized with the action signal of the push cylinder, ensuring that the battery casings are transported to the subsequent fixed workstations at a fixed rhythm. The modular design of the base and the shock-absorbing structure ensure the operational stability of each mechanism and adapt to different production environment requirements.

[0042] For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
