Description

A lithium battery cell rotary coating device Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically to a lithium battery cell rotating coating device. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] Existing lithium battery cell rotary wrapping devices generally require manual placement of the battery cells onto a rotating packaging table for fixation before wrapping. However, manual operation is time-consuming and labor-intensive. Therefore, we propose a lithium battery cell rotary wrapping device. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A lithium battery cell rotary coating device includes: a worktable and a feeding assembly disposed on the worktable, wherein a coating mechanism is mounted on the worktable; the feeding assembly includes a conveying mechanism disposed on the worktable, a lifting mechanism disposed inside the conveying mechanism, and a loading mechanism mounted on the worktable and located on the side of the conveying mechanism; the conveying mechanism includes a drive shaft embedded in the worktable, a conveyor belt disposed outside the drive shaft, a limiting plate fitted on the conveyor belt, a slot formed at the bottom of the limiting plate, and a positioning strip connecting two sets of the slots; the loading mechanism includes a feeding platform mounted on the worktable, a conveyor disposed on the feeding platform, a torsion spring shaft mounted at the end of the feeding platform, a unloading plate fixed on the torsion spring shaft, a photoelectric transmitter mounted at the bottom of the unloading plate, and a photoelectric receiver disposed within the limiting plate.

[0007] In a preferred embodiment, the present invention can be further configured such that: the lifting mechanism includes a fixed plate installed on the workbench and located inside the conveyor belt, an electric lifting rod embedded in the middle of the fixed plate, a lifting platform sleeved on the drive end of the electric lifting rod, and a through hole opened in the conveyor belt for the lifting platform to pass through.

[0008] In a preferred embodiment, the present invention can be further configured such that a soft rubber sleeve is fixed to the outside of the drive shaft.

[0009] In a preferred embodiment, the present invention can be further configured such that both ends of the positioning strip are curved upwards.

[0010] In a preferred embodiment, the present invention can be further configured such that the photoelectric transmitter is located directly above the photoelectric receiver.

[0011] In a preferred embodiment, the present invention can be further configured such that the limiting plates are arranged in pairs, and the distance between the two pairs of limiting plates is greater than half the length of the fixing plate.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model uses a feeding assembly to connect the feeding table to the product production line, allowing the battery cells to continuously move onto the feeding table. When the photoelectric transmitter detects the arrival of the photoelectric receiver below, the drive shaft stops, and the conveyor is driven to move the battery cells on the feeding table towards the lower material plate. When a single battery cell falls, the conveyor stops, and as the battery cell slides down the lower material plate, the torsion spring shaft will cause it to tilt downwards until the battery cell falls between the limit plates. Then, it moves to the top of the lifting platform and is fixed by the electric lifting rod for rotation and wrapping. This solution facilitates the automated operation of the wrapping machine and has high practicality.

[0014] 2. This utility model uses a feeding assembly to adjust the position of the limiting plate on the conveyor belt, making the limiting plates suitable for limiting battery cells of different sizes. With the addition of positioning strips on the inside to further position the limiting plates, the stability of the limiting plates can be effectively guaranteed, which is quite reasonable.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a lithium battery cell rotating coating device provided by this utility model.

[0026] As shown in Figures 1-3, the present invention provides a lithium battery cell rotary coating device, comprising: a worktable 100 and a feeding assembly 200 disposed on the worktable 100, wherein a coating mechanism 110 is installed on the worktable 100.

[0027] The feeding assembly 200 includes a conveying mechanism disposed on the workbench 100, a lifting mechanism disposed inside the conveying mechanism, and a loading mechanism installed on the workbench 100 and located on the side of the conveying mechanism. The conveying mechanism includes a drive shaft 210 embedded in the workbench 100, a conveyor belt 220 disposed outside the drive shaft 210, a limiting plate 230 fitted on the conveyor belt 220, a slot 240 formed at the bottom of the limiting plate 230, and a positioning strip 250 connecting two sets of slots 240. The loading mechanism includes a feeding platform 310 installed on the workbench 100, a conveyor 320 disposed on the feeding platform 310, a torsion spring shaft 330 installed at the end of the feeding platform 310, and a lower feeder fixed to the torsion spring shaft 330. The material plate 340, the photoelectric transmitter 350 installed at the bottom of the material plate 340, and the photoelectric receiver 360 set in the limiting plate 230 are connected to the product production line via the feeding assembly 200. The feeding table 310 is connected to the production line, so that the battery cells continuously move to the feeding table 310. When the photoelectric transmitter 350 detects the arrival of the photoelectric receiver 360 below, the drive shaft 210 stops, and the conveyor 320 is driven to move the battery cells on the feeding table 310 towards the material plate 340. When a single battery cell falls, the conveyor 320 stops. When the battery cell slides down the material plate 340, the torsion spring shaft 330 will cause it to tilt downwards until the battery cell falls between the limiting plates 230. Then it moves to the top of the lifting platform 430 and is fixed by the electric lifting rod 420 for rotation and wrapping. This scheme facilitates the automated operation of the wrapping machine and has high practicality.

[0028] Furthermore, the lifting mechanism includes a fixed plate 410 installed on the workbench 100 and located inside the conveyor belt 220, an electric lifting rod 420 embedded in the middle of the fixed plate 410, a lifting platform 430 sleeved on the driving end of the electric lifting rod 420, and a through hole 440 opened in the conveyor belt 220 for the lifting platform 430 to pass through. By driving the lifting platform 430 to rise through the electric lifting rod 420, the battery cells between the limiting plates 230 can be lifted and placed away from the conveyor belt 220. Then, with the movable connection between the lifting platform 430 and the electric lifting rod 420, the battery cells can be rotated and coated after the coating mechanism 110 presses them in place. This mechanism is highly practical.

[0029] On the other hand, a soft rubber sleeve 211 is fixed on the outside of the drive shaft 210. The soft rubber sleeve 211 can perform appropriate deformation and storage when it comes into contact with the lower part of the limiting plate 230 and the positioning strip 250, preventing damage caused by hard contact. The design is relatively reasonable.

[0030] Furthermore, the two ends of the positioning strip 250 are curved upwards to prevent the positioning strip 250 from bending when it comes into contact with the soft rubber sleeve 211 or the fixing plate 410 during movement, thus ensuring the stability of the positioning strip 250.

[0031] On the other hand, the photoelectric transmitter 350 is located directly above the photoelectric receiver 360. The photoelectric transmitter 350 and the photoelectric receiver 360 are the transmitting end and receiving end of the photoelectric sensor. When the two are on the same vertical line, it is considered that the limiting plate 230 stops at a suitable position below the feeding plate 340, thereby facilitating the accurate sliding of the battery cell between the limiting plates 230.

[0032] Furthermore, the limiting plates 230 are arranged in pairs, and the distance between the two sets of limiting plates 230 is greater than half the length of the fixing plate 410, which can prevent the two sets of battery cells from being too close to affect the operation of the coating mechanism 110.

[0033] The working principle and usage process of this utility model are as follows: First, the feeding table 310 is connected to the product assembly line, so that the battery cells continuously move to the feeding table 310. When the photoelectric transmitter 350 detects the arrival of the photoelectric receiver 360 below, the drive shaft 210 stops, and the conveyor 320 is driven to move the battery cells on the feeding table 310 towards the lower material plate 340. When a single battery cell falls, the conveyor 320 stops. When the battery cell slides down along the lower material plate 340, the torsion spring shaft 330 will cause it to tilt downwards until the battery cell falls between the limit plates 230. Then, it moves to the top of the lifting platform 430 and is fixed by the electric lifting rod 420 for rotation and wrapping. After the wrapping is completed, the battery cell falls down, and the drive shaft 210 restarts to drive the conveyor belt 220 to rotate until the next set of limit plates 230 moves to the lower material plate 340. The cycle can be repeated.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
