Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a cutting device for lithium battery production. Background Technology

[0002] The tabs of a lithium-ion battery are a raw material used in lithium-ion polymer battery products, such as mobile phone batteries, Bluetooth batteries, and laptop batteries. Batteries have positive and negative terminals, and the tabs are the metal conductors that connect the positive and negative terminals from the battery cell. Simply put, the tabs are the contact points during charging and discharging. These contact points are not the copper plates on the outside of the battery, but rather an internal connection. Currently, the tabs need to be cut during manufacturing, and this cutting is mostly done manually, which makes precise length adjustments impossible.

[0003] To address the aforementioned issues, the existing patent publication number CN214519028U, entitled "A Cutting Device for Lithium Battery Tab Production," proposes a new invention that uses a rotating lead screw to move a limiting plate. By referring to a scale line, the length of the limiting plate to the cutting groove can be adjusted, thereby precisely controlling the cutting length of the tab material and improving product quality. This invention is practical and suitable for widespread promotion and use.

[0004] However, when the aforementioned cutting devices, including existing cutting devices, are cutting the raw material tabs of lithium batteries, the tabs are thin and difficult to handle by hand, which in turn makes the unloading of the cut tabs inconvenient. Therefore, it is necessary to propose a cutting device for lithium battery production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting device for lithium battery production, so as to solve the problem mentioned above that when the existing cutting device for lithium battery production cuts the raw material tabs of lithium batteries, the tabs are thin and inconvenient to handle by hand, which makes it difficult to unload the cut tabs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for lithium battery production, comprising a base plate, a baffle and a support plate respectively fixedly disposed on both sides of the top of the base plate, a processing table fixedly disposed on the top of the support plate, a cutting assembly disposed on the processing table, a placement plate fixedly disposed on the side of the baffle, the processing table and the placement plate being at the same height, and a conveying assembly disposed on the top of the base plate, the conveying assembly being located between the placement plate and the processing table;

[0007] The conveying assembly includes two electric push rods fixedly mounted on the upper surface of the base plate. The two electric push rods are symmetrically arranged about the center line of the base plate. A U-shaped frame is fixedly connected between the telescopic ends of the two electric push rods. A conveyor belt is rotatably mounted on the U-shaped frame. In the initial state, the height of the top of the conveyor belt is lower than the height of the upper surface of the processing table.

[0008] Preferably, the cutting assembly includes two side plates, which are respectively fixedly installed at both ends of the top of the processing table. A top plate is fixedly connected between the ends of the two side plates. Two hydraulic cylinders are installed on the top plate. The two hydraulic cylinders are symmetrically arranged about the center line of the processing table. The telescopic ends of the hydraulic cylinders move through the bottom of the top plate, and a lifting plate is fixedly installed at one end that passes through the bottom of the top plate. Limiting components and cutting blades are respectively installed at both ends of the bottom of the lifting plate. A cutting groove is provided directly below the cutting blade and is opened inside the processing table.

[0009] Preferably, the limiting component includes a sleeve plate, which is fixedly disposed at the bottom of the lifting plate away from the cutting blade. A sliding groove is fixedly disposed inside the lifting plate, and a telescopic plate is movably disposed inside the sliding groove. Springs are fixedly connected between the two ends of the top of the telescopic plate and the end of the sliding groove. The telescopic plate is located directly above the placement plate.

[0010] Preferably, the upper surface of the processing table is fixedly provided with a plurality of equidistant limiting strips, and a tab is placed between adjacent limiting strips, the ends of the tabs and the baffles being in contact with each other.

[0011] Preferably, a protective plate is fixedly provided at the bottom of the top plate, and the other side of the protective plate is fixedly connected to the limiting strip.

[0012] Preferably, a motor is fixedly mounted on the side of the U-shaped frame, and a drive shaft and a driven shaft are rotatably mounted at both ends of the U-shaped frame, respectively. The drive end of the motor is fixedly connected to the drive shaft, and the conveyor belt is movably sleeved outside the drive shaft and the driven shaft.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. After the tabs are cut, the hydraulic cylinder is started to drive the cutting blade and telescopic plate to move upward and reset. At the same time, the electric push rod and motor are started, and the conveyor belt can then transport the cut tabs to the external collection box, avoiding the trouble of manual unloading. This solves the problem that existing lithium battery production cutting devices are inconvenient to unload after cutting the raw material tabs of lithium batteries because the tabs are thin and difficult to handle by hand.

[0015] 2. After quickly positioning the electrode tab, start the hydraulic cylinder to push the lifting plate, cutting blade, sleeve plate and telescopic plate downward. Through the cooperation of the cutting blade and cutting groove, the electrode tab is cut, and the telescopic plate presses down the other end of the electrode tab, thereby avoiding the problem of the electrode tab easily lifting and bending during cutting.

[0016] 3. When using this lithium battery production cutting device, place several tabs to be cut between the limiting strips in sequence, and push the tabs forward so that the ends of the tabs and the baffles fit together, which facilitates quick positioning of the tabs, improves the feeding efficiency, and allows multiple tabs to be cut at once, thus improving processing efficiency.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-5The cutting device for lithium battery production shown includes a base plate 1. A baffle 2 and a support plate 3 are fixedly installed on the two sides of the top of the base plate 1, respectively. A processing table 4 is fixedly installed on the top of the support plate 3. A cutting component is installed on the processing table 4. A placement plate 11 is fixedly installed on the side of the baffle 2. The processing table 4 and the placement plate 11 are at the same height. A conveying component is installed on the top of the base plate 1. The conveying component is located between the placement plate 11 and the processing table 4.

[0025] Furthermore, the conveying assembly includes two electric push rods 14 fixedly mounted on the upper surface of the base plate 1. The two electric push rods 14 are symmetrically arranged about the center line of the base plate 1. A U-shaped frame 15 is fixedly connected between the telescopic ends of the two electric push rods 14. A conveyor belt 16 is rotatably mounted on the U-shaped frame 15. In the initial state, the height of the top of the conveyor belt 16 is lower than the height of the upper surface of the processing table 4.

[0026] Furthermore, the cutting assembly includes two side plates 5, which are fixedly installed at both ends of the top of the processing table 4. A top plate 6 is fixedly connected between the ends of the two side plates 5. Two hydraulic cylinders 7 are installed on the top plate 6. The two hydraulic cylinders 7 are symmetrically arranged about the center line of the processing table 4. The telescopic end of the hydraulic cylinder 7 moves through the bottom of the top plate 6, and a lifting plate 8 is fixedly installed at one end that passes through the bottom of the top plate 6. Limiting components and cutting blades 9 are respectively installed at both ends of the bottom of the lifting plate 8. A cutting groove 10 is provided directly below the cutting blade 9 and is opened inside the processing table 4. Several equidistant limiting strips 12 are fixedly installed on the upper surface of the processing table 4, and tabs 13 are placed between adjacent limiting strips 12.

[0027] Furthermore, the limiting component includes a sleeve plate 17, which is fixedly installed at the bottom of the lifting plate 8 away from the cutting blade 9. A slide groove is fixedly installed inside the lifting plate 8, and a telescopic plate 18 is movably installed inside the slide groove. Springs are fixedly connected between the two ends of the top of the telescopic plate 18 and the end of the slide groove. The telescopic plate 18 is located directly above the placement plate 11.

[0028] When using this lithium battery production cutting device, several tabs 13 to be cut are placed between the limiting strips 12 in sequence, and the tabs 13 are pushed forward so that the ends of the tabs 13 and the baffles 2 fit together, which facilitates the quick positioning of the tabs 13, improves the feeding efficiency, and this setting makes it easy to cut multiple tabs 13 at one time, improving the processing efficiency.

[0029] After quickly positioning the tab 13, start the hydraulic cylinder 7 to push the lifting plate 8, cutting blade 9, sleeve plate 17 and telescopic plate 18 downward. Through the cooperation of the cutting blade 9 and the cutting groove 10, the tab 13 is cut, and the telescopic plate 18 presses down the other end of the tab 13, thereby avoiding the problem that the tab 13 is easy to lift and bend during cutting.

[0030] After cutting, the hydraulic cylinder 7 is reversed, driving the cutting blade 9 and the telescopic plate 18 to move upward and reset. At the same time, the electric push rod 14 is activated. Since the motor 20 is fixedly installed on the side of the U-shaped frame 15, and the two ends of the U-shaped frame 15 are respectively rotatably equipped with the drive shaft and the driven shaft, the drive end of the motor 20 is fixedly connected to the drive shaft, and the conveyor belt 16 is movably sleeved outside the drive shaft and the driven shaft. After the electric push rod 14 is activated, it pushes the U-shaped frame 15 and the conveyor belt 16 to move upward. The conveyor belt 16 lifts the cut tab 13, and then the motor 20 is activated. The conveyor belt 16 can then transmit the cut tab 13 to the external collection box, avoiding the trouble of manual unloading. This solves the problem of the existing lithium battery production cutting device cutting the raw material tab 13 of lithium batteries, which is thin and inconvenient to handle by hand, thus making the unloading operation of the cut tab 13 inconvenient.

[0031] Furthermore, a protective plate 19 is fixedly installed at the bottom of the top plate 6. The other side of the protective plate 19 is fixedly connected to the limiting strip 12. The protective plate 19 is used to prevent the hand from being pressed by the cutting blade 9, thus protecting the safety of employees.
