Description

Technical Field

[0001] This invention relates to the field of battery tab cutting technology, specifically a bidirectional adjustable tab quick-cutting mechanism. Background Technology

[0002] Battery tabs are metal conductors that connect the internal electrodes of a battery to the external circuitry. The positive electrode is typically made of aluminum, while the negative electrode is made of nickel or nickel-plated copper. They serve as the current contact points during charging and discharging, and also bear critical functions such as heat dissipation and short-circuit protection. Some tabs need to be cut to length before connection. Through a combination of mechanical clamping and blade cutting, the tabs are positioned precisely and dimensionally accurate during the cutting process, thereby ensuring the battery's conductivity and welding quality.

[0003] The invention disclosed in CN107946531B is a battery cell tab cutting device. The cylinder output end is connected to a concave arc upper cutter that moves downward with the cylinder output end and cooperates with a convex arc lower cutter to cut the battery cell tab. A positioning block is provided behind the convex arc lower cutter to limit the cutting length of the battery cell tab. By using the concave arc upper cutter and the convex arc lower cutter to cut the tab, the bending radius can be better prevented from exceeding the battery cell body, puncturing the aluminum-plastic film, causing safety accidents and battery scrapping.

[0004] The invention disclosed in CN111129418B is a lithium battery tab cutting device and a lithium battery. Under the drive of the power mechanism, the upper die can cut the outer edge of the tab, so that the outer edge of the tab after cutting is arc-shaped. Compared with the sharp and convex outer edge of the tab in the prior art, the tab with arc-shaped edge has a smoother transition. In the subsequent processing and transportation of the battery cell, the tab with arc-shaped edge can avoid damaging the separator on other battery cells.

[0005] However, the aforementioned cutting device for battery tabs still has the following problems in actual use: the cutting component cuts the tabs, but it is difficult for such cutting components to adapt to different specifications of battery tabs during operation. The position of the battery tabs of different specifications needs to be repeatedly adjusted. At the same time, during the transportation and movement of the battery, the tabs will undergo different shapes of flipping and deformation due to their own material, which will prevent them from making stable contact with the cutting component and affect the quality of the tab cutting.

[0006] Therefore, we propose a bidirectional adjustable electrode quick-cutting mechanism to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a bidirectional adjustable electrode quick-cutting mechanism to solve the problems of existing cutting components for cutting electrodes, which are difficult to adapt to different specifications of battery electrodes during operation. The position of the electrodes needs to be repeatedly adjusted for different specifications of batteries. At the same time, during the transportation and movement of the battery, the electrodes will undergo different shapes of flipping and deformation due to their own material, which will prevent them from making stable contact with the cutting components and affect the cutting quality of the electrodes.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a bidirectional adjustable electrode quick-cutting mechanism, comprising a battery body and an electrode body installed on the side of the battery body, wherein the battery body is installed above the conveying bracket.

[0009] The conveying bracket is equipped with a conveying cylinder at its bottom, and the conveying cylinder drives the conveying bracket and the battery body to move and convey through the conveying slide rail.

[0010] A material support is provided below the conveying bracket, and quick-cutting bases are provided on the front and rear sides of the material support, and an adjustment mechanism is provided above the quick-cutting bases.

[0011] A leveling mechanism is provided on the upper inner side of the quick-cut base, and the leveling mechanism includes a leveling arc frame, and a leveling scraper is fixedly installed at the bottom end of the leveling arc frame for fitting the tab body to achieve scraping and leveling.

[0012] Preferably, the adjusting mechanism includes an adjusting cylinder, which is fixedly installed in the lower middle part of the quick-cutting base, and the inner telescopic part of the adjusting cylinder is fixedly connected to the bottom end of the adjusting bracket, and the adjusting bracket is slidably installed on the upper end of the quick-cutting base.

[0013] Preferably, the adjusting mechanism includes lifting cylinders slidably installed on the left and right sides of the adjusting bracket, and a quick-cutting bracket is slidably installed on the upper part of the adjusting bracket, and the lower end of the quick-cutting bracket is fixedly connected to the upper extension part of the lifting cylinder, and quick-cutting cylinders are symmetrically installed on the top of the lifting cylinder.

[0014] Preferably, the adjusting mechanism includes a transmission slider, which is slidably installed on the left and right sides above the inner end of the quick-cutting bracket. The symmetrically arranged transmission sliders are fixedly connected to the lower telescopic part of the quick-cutting cylinder. The bottom outer side of the transmission slider is fixedly installed with a quick-cutting tool by bolts, and the bottom of the quick-cutting tool is obliquely distributed.

[0015] Preferably, the adjusting mechanism includes a positioning block, which is slidably installed below the transmission slider. Positioning slide rods are fixedly installed on both the left and right sides of the top surface of the positioning block, and the upper end of the positioning slide rod slides through the top of the transmission slider. The positioning slide rod and the transmission slider are connected by a contact spring.

[0016] Preferably, the leveling mechanism includes a leveling bracket, which is fixedly installed in the middle of the inner side of the left and right transmission sliders. A leveling shaft is rotatably installed on the inner side of the symmetrically arranged leveling brackets via a torsion spring. A dust blowing arc box is fixedly installed above the leveling bracket, and a one-way exhaust valve is installed through the inner end of the dust blowing arc box.

[0017] Preferably, the leveling mechanism includes a leveling arc frame with a telescopic sleeve at the upper end, and the telescopic sleeve is fixedly installed on the lower left and right sides of the leveling shaft, and the bottom ends of the symmetrically distributed leveling scrapers are provided with dust removal slots at equal intervals.

[0018] Preferably, the leveling mechanism includes a sealing plug plate fixedly installed on the outside of the telescopic sleeve, and the sealing plug plate is slidably installed inside the dust blowing arc box. The upper end of the one-way exhaust hose is connected through the lower inner side of the dust blowing arc box, and the lower end of the one-way exhaust hose is fixedly installed on the lower end of the leveling arc frame and is connected through the dust removal slots opened at equal intervals.

[0019] Preferably, the leveling scraper, positioning block, and quick-cutting blade are arranged in order from low to high, and the leveling scraper first contacts the tab body on the side of the battery body. When the adjusting mechanism descends, it squeezes the leveling arc frame, causing the leveling scraper to fit against the tab body and move to its side. After the positioning block descends and contacts the leveling arc frame, it drives the leveling arc frame to enter the telescopic sleeve along the inclined direction, thereby avoiding obstruction of the positioning and pressing of the tab body.

[0020] Preferably, the elastic force of the telescopic sleeve included in the leveling mechanism is less than the elastic force of the contact spring above the positioning block, and the positioning block first contacts the lower end of the leveling arc frame when it descends with the transmission slider, and squeezes the leveling arc frame to flip inward and move towards the telescopic sleeve, thereby scraping and leveling the electrode body and assisting in blowing away the residual dust.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This bidirectional adjustable tab quick-cutting mechanism adapts to the tab body of the conveyed battery body through an adjustable-distance quick-cutting component, and the tab body is scraped and leveled by a leveling component before the quick-cutting operation, so as to avoid deformation and dust adhesion affecting the cutting operation of the tab body. The specific details are as follows:

[0022] 1. The conveying cylinder drives the conveying bracket to move above the conveying slide rail. The conveying bracket moves relative to the battery body, and the material support supports the moving conveying bracket so that the battery body will shift or misalign when subjected to rapid cutting force.

[0023] The adjusting cylinder drives the adjusting bracket to move, avoiding collision between the battery body and the tab body inside the conveying bracket during movement. The lifting cylinder drives the quick-cutting bracket to adjust the height, thereby adapting and adjusting for different specifications of battery bodies and tab bodies.

[0024] 2. The quick-cut hydraulic cylinder drives the transmission slider and the leveling bracket to descend. The leveling arc frame connected to the leveling shaft moves downward in sync, so that the leveling scraper first contacts the battery body. The obliquely distributed leveling arc frame and the leveling scraper move synchronously to the side of the battery body, so as to drive the electrode body on the side of the battery body to be scraped and leveled, so as to avoid affecting the subsequent quick cut.

[0025] Furthermore, the transmission slider drives the positioning block to move downwards, which first contacts the bottom inclined surface of the leveling arc frame. At this time, the elastic force of the contact spring is greater than the elastic force of the telescopic sleeve, squeezing the leveling arc frame to move into the telescopic sleeve. At the same time, it pushes the leveling arc frame and the leveling scraper to rotate in opposite directions, so as to avoid obstructing the positioning operation between the positioning block and the electrode body.

[0026] 3. The telescopic sleeve drives the sealing plug plate to rotate and move inside the dust blowing arc box, so that the air is compressed and delivered to the dust removal slot through the through one-way exhaust hose. The dust removal slot at the bottom of the leveling scraper cleans the surface of the attached electrode body, avoiding dust adhering to the surface of the electrode body from causing scratches and damage during positioning and quick cutting.

[0027] Furthermore, the positioning block pushes the leveling arc frame in the opposite direction, making contact with the leveled tab body. As the transmission slider drives the quick-cutting tool to descend continuously, it compresses the resistance spring at the upper end of the positioning block, causing the positioning block to press and position the tab body before moving upward so that the quick-cutting tool can perform quick-cutting processing on the tab body after descending.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-10 The present invention provides the following technical solution:

[0041] Example 1: To solve the problems existing in the cutting of battery tabs, this example discloses the following technical solution: a bidirectional adjustable tab quick-cutting mechanism, including a battery body 1 and a tab body 2 installed on the side of the battery body 1, and the battery body 1 is installed above a conveying bracket 3; wherein, a conveying cylinder 26 is provided below the conveying bracket 3, and the conveying cylinder 26 drives the conveying bracket 3 and the battery body 1 to move and convey through a conveying slide rail 27; a material support 4 is provided below the conveying bracket 3.

[0042] The material carrier 4 is provided with quick-cutting bases 5 on the front and rear sides, and a distance adjustment mechanism is provided above the quick-cutting bases 5. The distance adjustment mechanism includes a distance adjustment cylinder 8, which is fixedly installed in the lower middle part of the quick-cutting base 5. The inner telescopic part of the distance adjustment cylinder 8 is fixedly connected to the bottom end of the distance adjustment bracket 9, and the distance adjustment bracket 9 is slidably installed on the upper end of the quick-cutting base 5. The distance adjustment mechanism includes lifting cylinders 10 slidably installed on the left and right sides of the distance adjustment bracket 9, and a quick-cutting bracket 11 is slidably installed above the distance adjustment bracket 9. The lower end of the quick-cutting bracket 11 is fixedly connected to the upper telescopic part of the lifting cylinder 10.

[0043] like Figures 1-3 As shown, the conveying cylinder 26 installed above the conveying slide rail 27 drives the top conveying bracket 3 to move. After moving to the inside of the quick-cutting base 5, the conveying cylinder 26 drives the top conveying bracket 3 to move into the inside of the material carrier 4. At the same time, the conveying bracket 3 supports the battery body 1, thereby realizing transmission and subsequent quick-cutting processing.

[0044] Furthermore, when the conveyor 3 moves the battery body 1 to the inside of the quick-cut base 5 on both sides, the adjusting cylinder 8 installed below the quick-cut base 5 drives the fixedly connected adjusting bracket 9 to move outward synchronously through its telescopic part, so as to avoid the battery body 1 and the tab body 2 inside the conveyor 3 from colliding during the movement. After the conveyor 3 moves the battery body 1 to the inside of the quick-cut base 5, the adjusting cylinder 8 drives the adjusting bracket 9 to move inward again to the required position. Then, the lifting cylinder 10 drives the quick-cut bracket 11 to adjust the height, so as to adapt and adjust the battery body 1 and the tab body 2 of different specifications.

[0045] Example 2: In order to solve the problems existing in the cutting of battery tabs, this example discloses the following technical solution: A leveling mechanism is provided on the upper inner side of the quick-cutting base 5, and the leveling mechanism includes a leveling arc frame 6, and a leveling scraper 7 is fixedly installed at the bottom end of the leveling arc frame 6 for scraping and leveling the tab body 2; the leveling mechanism includes a leveling bracket 18, and the leveling bracket 18 is fixedly installed in the middle of the inner side of the left and right side transmission sliders 13, and a leveling shaft 19 is rotatably installed on the inner side of the symmetrically arranged leveling bracket 18 through a torsion spring 28.

[0046] The top of the lifting cylinder 10 is symmetrically equipped with quick-cutting cylinders 12. The adjustment mechanism includes a transmission slider 13, which is slidably installed on the left and right sides above the inner end of the quick-cutting bracket 11. The symmetrically arranged transmission sliders 13 are fixedly connected to the lower telescopic part of the quick-cutting cylinder 12. The bottom outer side of the transmission slider 13 is fixedly installed with a quick-cutting cutter 14 by bolts. The bottom of the quick-cutting cutter 14 is obliquely distributed. The adjustment mechanism includes a positioning block 15, which is slidably installed below the transmission slider 13. The top left and right sides of the positioning block 15 are fixedly installed with positioning slide rods 16. The upper end of the positioning slide rods 16 slides through the top outer side of the transmission slider 13. The positioning slide rods 16 and the transmission slider 13 are connected by a contact spring 17.

[0047] like Figures 4-6 As shown, the quick-cutting cylinder 12 installed at the top of the quick-cutting bracket 11 operates. The transmission slider 13 connected to the telescopic part at its bottom drives the leveling bracket 18 to move downward synchronously. The leveling arc frame 6 connected to the leveling rotating shaft 19 inside the leveling bracket 18 descends so that the leveling scraper 7 at the bottom of the leveling arc frame 6 first contacts the upper surface of the battery body 1. During the continuous descent, the obliquely distributed leveling arc frame 6 and the leveling scraper 7 move synchronously to the side of the battery body 1 so as to drive the electrode body 2 on the side of the battery body 1 to be scraped and leveled, so as to avoid affecting the subsequent quick cut.

[0048] Furthermore, the transmission slider 13 synchronously drives the positioning block 15 connected to the positioning slide rod 16 to move downward. The positioning block 15 first contacts the bottom inclined surface of the leveling arc frame 6. At this time, the elastic force of the spring 17 above the positioning block 15 is greater than the elastic force of the telescopic sleeve 22, thereby squeezing the leveling arc frame 6 to move into the telescopic sleeve 22. At the same time, it pushes the leveling arc frame 6 and the leveling scraper 7 to rotate in opposite directions, so as to avoid obstructing the positioning operation between the positioning block 15 and the electrode body 2.

[0049] Example 3: In order to solve the problems existing in the cutting of existing battery tabs, this example discloses the following technical solution: the leveling mechanism includes a leveling arc frame 6 with a telescopic sleeve 22 at the upper end, and the telescopic sleeve 22 is fixedly installed on the lower left and right sides of the leveling shaft 19, and the bottom ends of the symmetrically distributed leveling scrapers 7 are provided with dust removal slots 23 at equal intervals.

[0050] The leveling scraper 7, positioning pressure block 15, and quick-cutting blade 14 are arranged in order from low to high. The leveling scraper 7 first contacts the tab body 2 on the side of the battery body 1. When the adjustment mechanism descends, it squeezes the leveling arc frame 6, causing the leveling scraper 7 to fit against the tab body 2 and move to its side. After the positioning pressure block 15 descends and contacts the leveling arc frame 6, it drives the leveling arc frame 6 to enter the telescopic sleeve 22 in an inclined direction, thereby avoiding obstruction of the positioning and pressing of the tab body 2.

[0051] The elastic force of the telescopic sleeve 22 included in the leveling mechanism is less than the elastic force of the spring 17 above the positioning block 15. When the positioning block 15 descends with the transmission slider 13, it first contacts the lower end of the leveling arc frame 6 and squeezes the leveling arc frame 6 to flip inward and move towards the telescopic sleeve 22, thereby scraping and leveling the tab body 2 and assisting in blowing away the residual dust.

[0052] A dust blowing arc box 20 is fixedly installed above the leveling bracket 18, and a one-way exhaust valve 21 is installed through the inner end of the dust blowing arc box 20. The leveling mechanism includes a sealing plug plate 24 fixedly installed on the outside of the telescopic sleeve 22, and the sealing plug plate 24 is slidably installed inside the dust blowing arc box 20. The upper end of the one-way exhaust hose 25 is connected through the lower inner side of the dust blowing arc box 20, and the lower end of the one-way exhaust hose 25 is fixedly installed on the lower end of the leveling arc frame 6 and is connected through the dust removal slots 23 that are opened at equal intervals.

[0053] like Figures 6-8 As shown, during the downward movement of the leveling bracket 18 and the leveling arc frame 6 driven by the transmission slider 13, the leveling arc frame 6 is squeezed and first drives the leveling scraper 7 to rotate outward. The telescopic sleeve 22 drives the sealing plug 24 to rotate and move inside the dust blowing arc box 20, so as to compress the air inside the dust blowing arc box 20. The air is then transported to the dust removal slot 23 connected at the lower end by the through-connected one-way exhaust hose 25. The dust removal slot 23 at the bottom of the leveling scraper 7 cleans and removes dust from the surface of the attached electrode body 2, so as to avoid scratches and damage caused by dust adhering to the surface of the electrode body 2 during the positioning and quick cutting process.

[0054] like Figures 9-10 As shown, after the positioning block 15 pushes the leveling arc frame 6 in the opposite direction, it comes into contact with the leveled tab body 2. When the transmission slider 13 drives the quick-cutting tool 14 to continue to descend, it compresses the contact spring 17 at the upper end of the positioning block 15, so that the positioning block 15 presses and positions the tab body 2 and then moves upward so that the quick-cutting tool 14 can perform quick-cutting processing on the tab body 2 after descending.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
