[0002] An electric cylinder punching machine is a piece of equipment specifically used in the production process of battery negative electrode materials (such as graphite). Its main function is to press the negative electrode material into the required shape and thickness to facilitate subsequent battery assembly and use.

[0003] For example, the national authorized patent announcement number CN210547339U discloses a punching machine for producing button batteries, including a base, a machine base on top of the base, a punch inside the machine base, a lower module on top of the base, and the lower module is detachably connected to the base. A electrode insertion mechanism is provided on the edge of the base. The beneficial effects of this utility model are as follows: the lower module on the punching machine is connected to the semi-perforated hole on the base by a slot, which can realize quick fitting and installation. Secondly, the electrode insertion mechanism is set on the base of the punching machine, and the electrode is inserted into the opening on the electrode insertion mechanism, which can make the position of the electrode more fixed and prevent the electrode from being skewed, thus affecting the processing accuracy. In addition, the inner plate of the electrode insertion mechanism is provided with a spring-loaded screw. Through the adjustable connection between the spring-loaded screw and the outer plate, the lateral distance of the opening can be adjusted, thereby accommodating the placement of electrode sheets of different widths.

[0004] However, the aforementioned punching machine used for producing button batteries cannot automatically push the pressed negative electrode sheet out of the cylindrical mold after pressing the negative electrode material into a sheet, making it inconvenient for workers to remove it. Utility Model Content

[0005] The purpose of this invention is to provide an electric cylinder punching machine to solve the problem mentioned in the background art that after the battery negative electrode material is pressed into sheets, the pressed negative electrode sheets cannot be automatically pushed out of the cylindrical mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric cylinder punching machine includes: an operating table, a connecting plate fixedly installed on the upper surface of the operating table, a first electric cylinder fixedly installed on the lower surface of the connecting plate, a punching plate fixedly installed on the lower end of the outer surface of the piston rod of the first electric cylinder, the punching plate being flush with a punching groove, the punching groove being formed on the upper surface of the operating table, and a pushing mechanism slidably installed in the punching groove, so that the punching plate can press the battery negative electrode material into a circular sheet shape in the punching groove and be located on the upper surface of the pushing mechanism;

[0008] The upper surface of the stamping groove is provided with an annular groove, which is flush with the stamping groove. A scraping mechanism is rotatably installed in the annular groove. The upper surface of the annular groove is provided with an inclined sliding surface, which can guide the tilted battery negative electrode material into the stamping groove.

[0009] Preferably, the leveling mechanism includes a torsion handle, which is rotatably mounted on the upper surface of the annular groove and located between two sets of stamping grooves. A scraper is fixedly mounted on the outer surface of the torsion handle, and the scraper is fitted into the annular groove.

[0010] Preferably, the scraper can scrape the battery negative electrode material protruding from the stamping groove into the annular groove, and the battery negative electrode material in the annular groove can be scraped into the communicating port by the scraper, and the communicating port is opened on the upper surface of the annular groove.

[0011] Preferably, the annular groove is connected to the sliding insertion port, which is located at one end of the operating table. A storage box can be slidably inserted into the sliding insertion port, so that the storage box can receive and store the battery negative electrode material that has been scraped out of the stamping groove.

[0012] Preferably, the pushing mechanism includes a pushing disk, which is slidably installed in the stamping groove. The lower surface of the pushing disk abuts against the bottom of the operating table. A sliding groove is provided at one end of the outer surface of the pushing disk, and the sliding groove is inclined from high to low.

[0013] Preferably, a sliding column is slidably installed inside the slide bar opening, the sliding column is located at the highest point of the slide bar opening, the sliding column is fixedly installed at one end of the piston rod of the second electric cylinder, and the second electric cylinder is fixedly installed inside the operating table.

[0014] Preferably, the sliding column can slide horizontally within the slide bar opening by being pushed by the second electric cylinder, and due to the sloping shape of the slide bar opening from high to low, the sliding column can push the pusher plate out of the stamping groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the design of the first electric cylinder, stamping plate, stamping groove, annular groove, scraping mechanism, and pushing mechanism, when pressing the battery negative electrode material into negative electrode sheets, the battery negative electrode material can be poured into the stamping groove. Then, the operator can rotate the scraping mechanism in the annular groove to scrape and push the battery negative electrode material protruding from the stamping groove into the connecting port for centralized storage. After being scraped, the battery negative electrode material is flat in the stamping groove, which ensures the consistency of the battery negative electrode material in the stamping groove and helps to improve the battery performance and cycle life. Then, the first electric cylinder can be started to drive the stamping plate on the lower surface of the piston rod to press into the stamping groove, which can press the battery negative electrode material in the stamping groove into negative electrode sheets. Then, the pushing mechanism can be started to push the pressed negative electrode sheets out of the stamping groove, which makes it easy for the operator to pick them up, improving production efficiency and operational convenience.

[0017] 2. Through the design of the torsion handle, scraper, and storage box, after the battery negative electrode material is poured into the stamping groove, the operator can turn the torsion handle to drive the scraper to rotate in the annular groove. This allows the scraper to scrape the battery negative electrode material protruding from the stamping groove and flatten it, ensuring the consistency of the battery negative electrode material. Excess material is swept into the annular groove. With continuous turning, the scraper can push the excess battery negative electrode material into the connecting port. The battery negative electrode material can then fall into the storage box through the connecting port for centralized storage, which helps to reuse these materials and reduce production costs and resource waste.

[0018] 3. Through the design of the second electric cylinder, sliding column, pusher plate, and slide bar opening, the second electric cylinder can be activated after the battery negative electrode material in the stamping groove is leveled. The second electric cylinder will push the pusher plate on the lower surface of the piston rod into the stamping groove, pressing the battery negative electrode material between the stamping plate and the pusher plate, thus completing the pressing of the battery negative electrode material in the stamping groove into a negative electrode sheet. Then, the second electric cylinder can be activated to push the sliding column at one end of the piston rod into the slide bar opening. Since the slide bar opening is inclined from high to low, and the sliding column is pushed horizontally, when the sliding column is pushed to the lower part of the slide bar opening, it drives the pusher plate to push out of the stamping groove. This allows the pusher plate to push the pressed negative electrode sheet out of the stamping groove, making it easier for workers to pick up the stamped negative electrode sheet. This improves the convenience and efficiency of operation, reduces production time, and helps ensure the integrity and quality of the product. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-6 This embodiment provides the following technical solution:

[0028] like Figures 1-2 As shown, an electric cylinder punching machine includes: an operating table 1, a connecting plate 101 fixedly installed on the upper surface of the operating table 1, a first electric cylinder 102 fixedly installed on the lower surface of the connecting plate 101, a punching plate 103 fixedly installed on the lower end of the outer surface of the piston rod of the first electric cylinder 102, the punching plate 103 being flush with the punching groove 104, the punching groove 104 being opened on the upper surface of the operating table 1, and a pushing mechanism 3 being slidably installed in the punching groove 104, so that the punching plate 103 can press the battery negative electrode material into the punching groove 104 in a circular shape and at the upper surface of the pushing mechanism 3;

[0029] The upper surface of the stamping groove 104 is provided with an annular groove 106, which is flush with the stamping groove 104. A scraping mechanism 2 is rotatably installed in the annular groove 106. An inclined sliding surface 105 is provided on the upper surface of the annular groove 106, which can guide the tilted battery negative electrode material into the stamping groove 104.

[0030] Through the design of the first electric cylinder 102, stamping plate 103, stamping groove 104, annular groove 106, scraping mechanism 2, and pushing mechanism 3, when pressing the battery negative electrode material into a negative electrode sheet, the battery negative electrode material can be poured into the stamping groove 104. Then, the operator can rotate the scraping mechanism 2 in the annular groove 106, which scrapes and pushes the battery negative electrode material protruding from the stamping groove 104 into the connecting port 108 for centralized storage. After being scraped, the battery negative electrode material can be further processed during the stamping process. The pressure groove 104 is flat, which ensures the consistency of the battery negative electrode material in the pressure groove 104, which helps to improve the battery performance and cycle life. Then, the first electric cylinder 102 can be started to drive the pressure plate 103 on the lower surface of the piston rod to press into the pressure groove 104, which can press the battery negative electrode material in the pressure groove 104 into a negative electrode sheet. Then, the pushing mechanism 3 can be started to push the pressed negative electrode sheet out of the pressure groove 104, which makes it easy for workers to pick it up, improving production efficiency and operation convenience.

[0031] like Figures 3-4 As shown, the leveling mechanism 2 includes a torsion handle 201, which is rotatably mounted on the upper surface of the annular groove 106 and located between two sets of stamping grooves 104. A scraper 202 is fixedly mounted on the outer surface of the torsion handle 201 and is fitted into the annular groove 106.

[0032] The scraper 202 can scrape the battery negative electrode material protruding from the stamping groove 104 into the annular groove 106. The battery negative electrode material in the annular groove 106 can be scraped into the connecting port 108 by the scraper 202. The connecting port 108 is opened on the upper surface of the annular groove 106.

[0033] The annular groove 106 is connected to the sliding insertion port 107. The sliding insertion port 107 is located at one end of the operating table 1. A storage box 203 can be slidably inserted into the sliding insertion port 107, so that the storage box 203 can receive and store the battery negative electrode material that has been scraped out of the stamping groove 104.

[0034] Through the design of the torsion handle 201, scraper 202, and storage box 203, after the battery negative electrode material is poured into the stamping groove 104, the operator can turn the torsion handle 201 to drive the scraper 202 to rotate in the annular groove 106. This allows the scraper 202 to scrape the battery negative electrode material protruding from the stamping groove 104 to flatten it, ensuring the consistency of the battery negative electrode material. Excess material is swept into the annular groove 106. With continuous turning, the scraper 202 can push the excess battery negative electrode material into the connecting port 108. The battery negative electrode material can then fall into the storage box 203 through the connecting port 108 for centralized storage, which helps to reuse these materials and reduce production costs and resource waste.

[0035] like Figures 5-6As shown, the pushing mechanism 3 includes a pushing disk 303, which is slidably installed in the stamping groove 104. The lower surface of the pushing disk 303 is in contact with the bottom of the operating table 1. A sliding groove 304 is provided at one end of the outer surface of the pushing disk 303, and the sliding groove 304 is inclined from high to low.

[0036] A sliding column 302 is slidably installed inside the slide bar opening 304. The sliding column 302 is located at the highest point of the slide bar opening 304. The sliding column 302 is fixedly installed at one end of the piston rod of the second electric cylinder 301. The second electric cylinder 301 is fixedly installed inside the operating table 1.

[0037] The sliding column 302 can slide horizontally within the slide bar opening 304 by being pushed by the second electric cylinder 301. Due to the sloping shape of the slide bar opening 304 from high to low, the sliding column 302 can push the pusher plate 303 out of the stamping groove 104.

[0038] Through the design of the second electric cylinder 301, sliding column 302, pusher plate 303, and sliding strip opening 304, after the battery negative electrode material in the stamping groove 104 is scraped flat, the second electric cylinder 301 can be activated. The second electric cylinder 301 will push the pusher plate 303 on the lower surface of the piston rod into the stamping groove 104, pressing the battery negative electrode material between the stamping plate 103 and the pusher plate 303, thus completing the pressing of the battery negative electrode material in the stamping groove 104 into a negative electrode sheet. Then, the second electric cylinder 301 can be activated to push the sliding column 302 at one end of the piston rod into the sliding strip opening 304. The slide bar 304 is pushed and slid within the slide bar opening 304. Since the slide bar opening 304 is inclined from high to low, and the sliding column 302 is kept horizontally pushed, when the sliding column 302 is pushed to the lower part of the slide bar opening 304, it drives the pusher plate 303 to push out of the stamping groove 104. The pusher plate 303 can then push the pressed negative electrode sheet out of the stamping groove 104, making it easier for workers to pick up the stamped negative electrode sheet. This improves the convenience and efficiency of operation, reduces production time, and helps ensure the integrity and quality of the product.

[0039] Based on the above technical solution, the working steps of this solution are summarized as follows: When pressing the battery negative electrode material into a negative electrode sheet, the battery negative electrode material can be poured into the stamping groove 104. Then, the operator can turn the torsion handle 201 to drive the scraper 202 to rotate in the annular groove 106. This allows the scraper 202 to scrape and flatten the battery negative electrode material protruding from the stamping groove 104, ensuring the consistency of the battery negative electrode material, and sweeping away excess material into the annular groove 106. With continuous turning, the scraper 202 can push the excess battery negative electrode material into the connecting port 108. The battery negative electrode material can then fall into the storage box 203 for centralized storage through the connecting port 108. After the battery negative electrode material in the stamping groove 104 is flattened, the second electric cylinder 301 can be started. The electric cylinder 301 pushes the pusher plate 303 on the lower surface of the piston rod into the stamping groove 104, pressing the battery negative electrode material between the stamping plate 103 and the pusher plate 303, thus completing the pressing of the battery negative electrode material in the stamping groove 104 into a negative electrode sheet. Then, the second electric cylinder 301 can be activated to push the sliding column 302 at one end of the piston rod into the sliding slot 304. Since the sliding slot 304 is inclined from high to low, and the sliding column 302 is kept horizontally pushed, when the sliding column 302 is pushed to the lower part of the sliding slot 304, it can drive the pusher plate 303 out of the stamping groove 104, so that the pusher plate 303 can push the pressed negative electrode sheet out of the stamping groove 104, making it easier for the staff to take out the stamped negative electrode sheet.

[0040] In summary, this allows the pressed negative electrode sheet to be pushed out of the stamping groove 104, making it easier for workers to pick up the pressed negative electrode sheet. This improves the convenience and efficiency of operation, reduces production time, and helps ensure the integrity and quality of the product.
