Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery production equipment, specifically a dustproof battery electrode sheet punching and cutting machine. Background Technology

[0002] With the development of new energy vehicles, the requirements for lithium-ion power batteries are becoming increasingly stringent. Currently, in the manufacturing process of lithium batteries, battery electrodes are generally produced using punching and cutting machines. During the cutting process with punching and cutting dies, dust such as metal or coating debris is inevitably generated.

[0003] Under the pressure of the upper and lower die during punching, the dust particles, due to the plastic deformation of the metal, cause the temperature to rise and adhere to the cutting edge of the punching blade, resulting in burrs on the electrode sheets during punching. If burrs appear on the edges of the positive and negative electrode sheets of lithium batteries during cutting, it can cause a short circuit, leading to battery self-discharge or even a safety accident. Therefore, this application proposes a dustproof battery electrode sheet punching and cutting machine to solve the above problems. Utility Model Content

[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: a dustproof battery electrode sheet punching and cutting machine, including: a main body mechanism and a cleaning mechanism, wherein the main body mechanism includes a frame, a first electric push rod symmetrically fixed at the top of the frame and a die-cutting head fixed at the bottom of the first electric push rod.

[0006] The cleaning mechanism includes a bracket symmetrically fixed on the frame, a cleaning component that is slidably sleeved on the bracket at both ends, a second electric push rod fixed on one side of the frame and whose end is fixedly connected to the cleaning component, an air extraction component fixed on one side of the frame, a hose connecting the air extraction component and the cleaning component, and a collection component that is installed at the bottom of the air extraction component and extends into the inner cavity of the air extraction component by a threaded connection.

[0007] In a preferred embodiment, the present invention can be further configured such that the cleaning component includes a sleeve slidably fitted on a bracket, a trapezoidal box with both ends fixed to the sleeve, and a plurality of brushes fixed to the top of the trapezoidal box.

[0008] In a preferred embodiment, the present invention can be further configured such that: the air extraction component includes a housing fixed to one side of the frame and a high-speed fan installed in the inner cavity of the housing; one end of the hose is connected to the inner cavity of the trapezoidal box, and the other end is connected to the inner cavity of the housing.

[0009] In a preferred embodiment, the present invention can be further configured such that the collecting component includes a cylinder that is threadedly connected to the bottom of the housing and extends into the inner cavity of the housing, and a filter screen fixed to the bottom of the cylinder.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, a hanging bracket is symmetrically fixed on the frame of the punching and cutting machine, and a cleaning component is slidably set on the hanging bracket. At the same time, a second electric push rod is fixed on one side of the frame, and the end of the second electric push rod is fixedly connected to the cleaning component. With the above arrangement, after the die-cutting head completes the punching and resets, the second electric push rod is activated, driving the cleaning component to move. The brush in the cleaning component moves to sweep away the dust attached to the die-cutting head and make it fall into the trapezoidal box for collection. This effectively avoids the phenomenon of dust sticking to the die-cutting head and causing burrs to be generated on the electrode sheet during punching, thus increasing the practical performance.

[0011] 2. In this utility model, air extraction components are symmetrically fixed on one side of the frame. The air extraction components are connected to the trapezoidal box through a hose, and a collection component is installed at the bottom of the air extraction components through a threaded connection. With the above configuration, when the air extraction components are activated, the air inside the trapezoidal box can be extracted through the hose. At this time, the dust inside the trapezoidal box follows the airflow into the air extraction components and is collected by the collection component, completing the dust collection operation and preventing dust from accumulating in the trapezoidal box, further increasing the practical performance.

Detailed Implementation

[0014] 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.

[0015] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1: Combination Figure 1-3As shown, this embodiment provides a dustproof battery electrode sheet punching and cutting machine, including: a main body mechanism 100 and a cleaning mechanism 200.

[0016] The main structure 100 includes a frame 110, a first electric push rod 120 symmetrically fixed to the top of the frame 110, and a die-cutting head 130 fixed to the bottom of the first electric push rod 120.

[0017] The frame 110 is used to install other components, and the first electric push rod 120 is used to install the die-cutting head 130 and drive the die-cutting head 130 to move up and down. The die-cutting head 130 is used to cut lithium battery electrode sheets.

[0018] The cleaning mechanism 200 is used to clean the dust adhering to the die-cutting head 130. It includes a bracket 210 symmetrically fixed on the frame 110, a cleaning component 220 with both ends slidably sleeved on the bracket 210, a second electric push rod 230 fixed on one side of the frame 110 and fixedly connected at its end to the cleaning component 220, an air extraction component 240 fixed on one side of the frame 110, a hose 250 connecting the air extraction component 240 and the cleaning component 220, and a collection component 260 installed at the bottom of the air extraction component 240 and extending into the inner cavity of the air extraction component 240 by a threaded connection.

[0019] The bracket 210 is used to install the cleaning component 220 and limit the movement of the cleaning component 220. The cleaning component 220 includes a sleeve 223 slidably sleeved on the bracket 210, a trapezoidal box 221 with both ends fixed to the sleeve 223, and multiple brushes 222 fixed to the top of the trapezoidal box 221. The end of the second electric push rod 230 is fixedly connected to one side of the trapezoidal box 221. With the above arrangement, when the second electric push rod 230 extends or retracts, it drives the trapezoidal box 221 to move. The movement of the trapezoidal box 221 drives the brushes 222 to move. The brushes 222 move close to the bottom end of the die-cutting head 130 to scrape off the dust attached to the die-cutting head 130. Under the action of gravity, the dust can fall into the trapezoidal box 221. The sleeve 223 is slidably sleeved on the bracket 210 to ensure the stability of the trapezoidal box 221 when it moves.

[0020] The air extraction component 240 includes a housing 241 fixed to one side of the frame 110 and a high-speed fan 242 installed inside the housing 241. One end of the hose 250 is connected to the inner cavity of the trapezoidal box 221, and the other end is connected to the inner cavity of the housing 241. When the high-speed fan 242 is started, it exhausts the air inside the housing 241, creating a negative pressure inside the housing 241. Under the action of air pressure, the air inside the trapezoidal box 221 enters the inner cavity of the housing 241 through the hose 250. At the same time, the dust in the trapezoidal box 221 can enter the inner cavity of the housing 241 with the airflow, preventing the dust from accumulating inside the trapezoidal box 221.

[0021] The collector 260 collects dust from the airflow and includes a cylinder 261 that is threadedly connected to the bottom of the housing 241 and extends into the inner cavity of the housing 241, and a filter screen 262 fixed to the bottom of the cylinder 261. The inner wall of the housing 241 has an internal thread, and the outer surface of the cylinder 261 has an external thread. The two threads mesh with each other, which facilitates the installation and disassembly of the cylinder 261. The filter screen 262 is used to filter the dust in the airflow and collect it in the inner cavity of the cylinder 261 for subsequent processing.

[0022] The working principle and usage process of this utility model are as follows: When in use, after the die-cutting head 130 completes the cutting of the electrode sheet, the second electric push rod 230 is activated, driving the cleaning component 220 to move. At this time, the brush 222 moves close to the bottom end of the die-cutting head 130, scraping off the dust attached to the die-cutting head 130. The scraped dust falls into the trapezoidal box 221 under the action of gravity. At the same time, the high-speed fan 242 is activated, drawing the air in the trapezoidal box 221 into the inner cavity of the housing 241 through the hose 250. At this time, the dust in the trapezoidal box 221 follows the airflow and enters the inner cavity of the housing 241 through the hose 250. The air is discharged through the filter screen 262 at the bottom of the cylinder 261, while the dust is intercepted by the filter screen 262 and accumulates in the cylinder 261, completing the dust collection.

[0023] 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.
