Description

Technical Field

[0001] The invention relates to the technical field of lithium battery pole piece laser cutting, and in particular to a lithium battery pole piece laser cutting waste collection box. Background Art

[0002] During the production process of wound lithium batteries, it is necessary to cut the positive and negative pole pieces into tabs, and the existing method of cutting lithium battery pole pieces usually adopts laser cutting. During the laser cutting process, a large amount of waste and dust are easily generated. The existing laser cutting method of collecting these wastes is usually to collect them into a waste box through negative pressure adsorption. However, due to the limited volume capacity of the waste box, after the waste box collects and loads a certain amount of waste, the traditional processing method is to shut down the laser cutter to clean the waste box to avoid excessive waste accumulation in the waste box. However, this transmission method of handling waste requires shutdown, which makes the production efficiency of lithium battery pole piece laser cutting low.

[0003] The existing method to improve the efficiency of laser cutting waste treatment is to compress the waste in the waste box so that the waste box can collect as much waste as possible, and then stop the machine for treatment. However, this method does not completely solve the problem of stopping the machine to treat the waste in the waste box. It only reduces the number of shutdowns for treatment, but cannot achieve complete non-stop treatment of waste. The production efficiency is still low. In the current situation of large-scale production demand for lithium batteries, this method of stopping the machine to treat waste obviously cannot meet the production capacity demand.

[0033] See also Figure 1~Figure 3 As shown, the lithium battery pole piece laser cutting waste collection box of the present invention comprises a box body 1. A compression chamber 10 is provided on the box body 1. Specifically, in one embodiment, the compression chamber 10 is provided at the upper part of the box body 1, and the lower part of the box body 1 is a hollow compressed waste collection chamber 11; a double door is provided on the box body 1 corresponding to the compressed waste collection chamber 11, or the compressed waste collection chamber 11 is an overhead structure to facilitate the removal of compressed waste.

[0034] An inlet 100 is provided at the top of the compression chamber 10. Specifically, the inlet 100 is provided in the middle of the compression chamber 10. Waste materials produced by cutting with the laser cutting machine will directly fall from the inlet 100 into the compression chamber 10, thereby being compressed.

[0035] A horizontal compression plate 2 is provided in the compression chamber 10, wherein the compression surface of the horizontal compression plate 2 is perpendicular to the horizontal plane. Furthermore, the horizontal compression plate 2 can move horizontally in the compression chamber. Specifically, in an optional embodiment, the horizontal compression plate 2 is movably provided in the compression chamber 10 by a horizontal screw rod 4, and the horizontal compression plate 2 can be driven to move in the horizontal direction by driving the horizontal screw rod 4 with power. When the collection box is collecting waste, the waste falling from the inlet 100 into the compression chamber 10 will be accumulated and compressed on both sides of the compression chamber 10 under the compression pushed by the horizontal movement of the horizontal compression plate 2.

[0036] Thus, the compression chamber 10 is divided into several compression chambers by the horizontal compression plate 2. In an optional embodiment, the compression chamber 10 includes compression chamber I101 and compression chamber II102 which are divided and distributed on the left and right. Since the horizontal compression plate 2 can move in the horizontal direction, the compression chamber I101 and the compression chamber II102 are chambers with variable volumes. Moreover, a vertical compression plate 3 is provided in the compression chamber I101 and the compression chamber II102 on the side away from the inlet 100, that is, a vertical compression plate 3 is provided in the compression chamber I101 and the compression chamber II102, and the vertical compression plate 3 is located at the upper top of the left and right sides of the compression chamber 10 near the edge. When compressing waste materials, the vertical compression plate 3 can move downward to compress the waste materials into shape, and can move upward to return to its original position after compression is completed.

[0037] Furthermore, the compression surface of the vertical compression plate 3 is parallel to the horizontal plane. The vertical compression plate 3 can move up and down in the vertical direction. Specifically, the vertical compression plate 3 is movably arranged in the compression chamber 10 through the vertical screw rod 5. The vertical compression plate 3 can be driven to move up and down in the vertical direction by driving the vertical screw rod 5 with power.

[0038] During operation, the waste material falling from the inlet 100 into the compression chamber 10 is pushed to the two sides of the compression chamber 10 by the horizontal movement of the horizontal compression plate 2 and then compressed downward by the vertical compression plate 3, so that the waste material can be further compressed into a mass, thereby reducing the volume of the waste material and facilitating the collection and transportation of the waste material.

[0039] In a specific embodiment, the width of the vertical compression plate 3 is less than half of the width of the compression chamber 10. In this way, it can be ensured that the waste materials falling from the inlet 100 into the compression chamber 10 can be diverted and pushed to the two sides of the compression chamber 10 by the horizontal movement of the horizontal compression plate 2 for accumulation and compression, and then further compressed and formed by the vertical compression plate 3, ensuring that the vertical compression plates 3 in the compression chamber Ⅰ101 and the compression chamber Ⅱ102 can completely perform independent compression work independently and are not affected by the inlet 100, so as to achieve continuous and uninterrupted alternating cycle compression work of the compression chamber Ⅰ101 and the compression chamber Ⅱ102.

[0040] The bottom of the compression chamber I 101 and the compression chamber II 102 are both provided with an outlet 103, and the waste blocks compressed and formed in the compression chamber I 101 and the compression chamber II 102 are discharged from the respective outlets 103. In addition, the opening width of the outlet 103 is greater than or equal to the width of the vertical compression plate 3, so that the compressed and formed waste blocks can be discharged from the outlet 103 smoothly.

[0041] Moreover, an outlet valve 6 is provided at the outlet 103; the outlet valve 6 is openable and closable at the outlet 103. When the waste is compressed, the outlet valve 6 can be closed to prevent the waste from leaking out; and the outlet valve 6 corresponds to the vertical compression plate 3, and can cooperate with the vertical compression plate 3 to assist in the compression of the waste during the compression operation. When the waste is compressed and discharged, the outlet valve 6 will be opened to discharge the compressed waste.

[0042] An outlet 103 is respectively provided at the bottom of compression chamber I 101 and compression chamber II 102, and an outlet valve 6 is provided on the outlet 103. The outlet 103 and the outlet valve 106 on compression chamber I 101 and compression chamber II 102 are independent of each other and do not interfere with each other, thereby ensuring that compression chamber I 101 and compression chamber II 102 can realize continuous and uninterrupted alternating cycle compression work.

[0043] For details, see Figure 4a and Figure 4b As shown, in a preferred embodiment, the outlet valve 6 is openably and closably arranged at the outlet 103 via a moving component 7 .

[0044] The moving assembly 7 includes a moving power member 71 and a guide member 72. Specifically, in an optional embodiment, the moving power member 71 is a cylinder or an oil cylinder, and the guide member 71 is a guide rail. The outlet valve 6 is slidably arranged on the guide member 72. The power output end of the moving power member 71 is transmission-connected with the outlet valve 6. The guide length direction of the guide member 72 is the same as the moving direction of the outlet valve 6. During operation, the outlet valve 6 is driven by the moving power member 71 to move back and forth on the guide member 72, thereby realizing the opening or closing of the outlet valve 6 on the outlet 103.

[0045] In another preferred embodiment, a receiving hopper 8 is provided below the outlet 103. When compressed material blocks are output, the material can be received at the discharge port of the receiving hopper 8. The receiving hopper 8 can facilitate the centralized collection of compressed material blocks and avoid the scattering of the material blocks. In an optional embodiment, the receiving hopper 8 is eccentrically arranged with respect to the outlet 103. The compressed material blocks discharged from the outlet 103 will slide along the inclined surface of the receiving hopper 8 to the discharge port of the receiving hopper 8, which is conducive to the centralized discharge of compressed material blocks and can effectively avoid the material blocks blocking the discharge port of the receiving hopper 8.

[0046] In another preferred embodiment, the inlet 100 is also connected to a dust suction port 104, which can be connected to a vacuum cleaner to vacuum the waste entering the compression chamber to avoid excessive dust accumulation in the compression chamber 10 and affect the working efficiency of the collection box and the service life of components.

[0047] In addition, in another preferred embodiment, universal wheels are also provided at the bottom of the box body 1, so that the position of the entire collection box can be quickly moved and converted as needed, and the application flexibility is high.

[0048] When the collection box of the present invention is used to collect laser cutting waste, refer to Figure 5 As shown. In the compressed waste collection chamber 11, on the receiving hopper 8 at the outlet of the corresponding compression chamber Ⅰ101 and compression chamber Ⅱ102, the receiving container 9 is placed. First, the horizontal compression plate 2 is driven to move rightward, and the waste dropped from the inlet 100 is pushed to the right and accumulated and compressed in the compression chamber Ⅱ102 on the right side of the compression chamber 10, and then the vertical compression plate 3 on the compression chamber Ⅱ102 is driven to move downward, and the accumulated and compressed waste in the compression chamber Ⅱ102 is further compressed and formed, and then the outlet valve 6 at the outlet 103 of the compression chamber Ⅱ102 is opened to release the compressed waste in the compression chamber Ⅱ102, and introduce it into the corresponding receiving container 9 through the receiving hopper 8 below the compression chamber Ⅱ102. Then, when the waste material dropped from the inlet 100 reaches a preset compression amount, the horizontal compression plate 2 is driven to move to the left, and the waste material dropped from the inlet 100 is pushed to the left and accumulated and compressed in the compression chamber Ⅰ101 on the left side of the compression chamber 10, and then the vertical compression plate 3 on the compression chamber Ⅰ101 is driven to move downward, and the accumulated and compressed waste material in the compression chamber Ⅰ101 is further compressed and formed, and then the outlet valve 6 at the outlet 103 of the compression chamber Ⅰ101 is opened to release the compressed waste material in the compression chamber Ⅰ101, and the waste material is introduced into the corresponding receiving container 9 through the receiving hopper 8 below the compression chamber Ⅰ101. During this process, the laser cutting machine continues to work, and waste continues to fall into the inlet 100. The horizontal compression plate 2 diverts the fallen waste into the compression chamber Ⅰ101 and the compression chamber Ⅱ102 for compression molding. In this way, the compression chamber Ⅰ101 and the compression chamber Ⅱ102 can realize continuous and uninterrupted alternating cycle compression work, and the bottom of the two compression chambers are provided with an outlet 103 for compressed material discharge, so that the overall waste collection box can realize continuous and uninterrupted compression and discharge, and further realize the non-stop waste collection and processing of the laser cutting machine, which is beneficial to the non-stop continuous operation of the laser cutting machine and improves the production efficiency of lithium battery pole pieces.
