Description

Technical Field

[0001] The present application relates to a high-speed cutting die for battery pole pieces, and in particular to a material pressing and dust removal device for the high-speed cutting die for battery pole pieces. Background Art

[0002] In the battery manufacturing process, the cutting of the pole piece is a key step, which directly affects the performance and safety of the battery. However, during the high-speed cutting process, a large amount of dust will be generated due to the friction between the materials and the action of the cutting tool. This dust not only pollutes the working environment, but also may damage the cutting tool and the battery pole piece itself, affecting the cutting accuracy and the quality of the battery pole piece. In addition, the accumulation of dust may also cause equipment failure and increase maintenance costs.

[0003] In order to solve this problem, people have tried many methods, such as improving the cutting process, using higher quality cutting tools, etc., but these methods can only reduce the generation of dust to a certain extent, but cannot fundamentally solve the problem. Utility Model Content

[0004] The purpose of this application is to provide a pressing dust removal device for a high-speed cutting mold for battery pole pieces, which can effectively remove the dust generated during the cutting process. It is of great significance for improving the accuracy and efficiency of battery pole piece cutting, as well as ensuring the cleanliness of the production environment and the stable operation of the equipment.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A press dust removal device for a high-speed cutting die for battery pole pieces comprises a press plate and a dust removal device; the dust removal device comprises a dust removal chamber, a dust removal exhaust port and a dust removal pipe arranged in the press plate, the dust removal exhaust port is arranged on the side of the press plate, the dust removal exhaust port is connected with the dust removal chamber, the dust removal chamber is connected with the dust removal pipe, the dust removal pipe exhausts air from the dust removal chamber, and the dust removal chamber removes dust from an upper cutting knife portion through the dust removal exhaust port.

[0007] Furthermore, the dust removal and air extraction port comprises an extension portion of a pressing plate and a dust removal port cover plate, and the dust removal port cover plate is detachably covered on the extension portion of the pressing plate to form the dust removal and air extraction port.

[0008] Furthermore, an inclined surface is provided on the bottom surface of the dust removal port cover plate near the dust removal and air extraction port, and the closer the inclined surface is to the dust removal and air extraction port, the smaller the distance between the extension portion of the pressing plate is.

[0009] Furthermore, the height of the dust removal air outlet is smaller than the height of the dust removal chamber.

[0010] Furthermore, connecting holes are respectively provided on both sides of the pressing plate. When one of the connecting holes is used to connect the dust removal pipe, the other connecting hole is blocked with a plug.

[0011] Furthermore, reinforcing ribs are vertically arranged in the dust removal chamber, and the reinforcing ribs are used to support the upper wall and the lower wall of the dust removal chamber.

[0012] Furthermore, the reinforcing ribs extend along the width direction of the dust removal chamber.

[0013] The beneficial effects of this application are:

[0014] The dust removal pipe of the present application is connected to an external negative pressure source (such as a vacuum pump). When the dust removal pipe starts working, it will generate a negative pressure environment in the dust removal chamber. This negative pressure is the main driving force for the movement of dust. During the cutting process, dust is generated when the upper cutter part contacts the battery electrode. Since the dust removal chamber is adjacent to the cutting area and is connected to the dust removal chamber through the dust removal exhaust port, the dust is quickly sucked into the dust removal chamber under the action of negative pressure. And when the upper cutter part moves upward through the dust removal exhaust port, the dust on the upper cutter part will be further removed; the dust entering the dust removal chamber is transmitted to an external collection device (such as a dust collection bag or a dust treatment system) through the dust removal pipe along with the air flow. In this process, the dust is effectively isolated to avoid secondary pollution to the working environment. Since the dust removal device is directly arranged near the cutting area and the dust is quickly collected by negative pressure suction technology, the dust removal efficiency is extremely high. This helps to keep the working environment clean and reduce dust pollution to equipment and products. Timely removal of dust reduces its adhesion to cutting tools and battery pole pieces, thereby improving cutting accuracy and the quality of battery pole pieces. This is crucial for the production of high-performance, high-quality battery products. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] A battery pole piece high-speed cutting die comprises an upper die, a first guide assembly and a lower die. The upper die is slidably mounted on the first guide assembly, the first guide assembly is mounted on the lower die, and the first guide assembly comprises a guide column and a guide sleeve.

[0027] like Figure 1 As shown, the upper mold includes an upper mold plate 11 and an upper cutting plate 12. The upper cutting plate 12 is arranged at the bottom of the upper mold plate 11. The upper cutting plate 12 extends downward near the side of the battery electrode for cutting to form an upper cutting portion 121. The upper cutting portion 121 is integrally formed with the upper cutting plate 12. The lower mold includes a lower mold plate 31 and a lower mold bottom plate 32.

[0028] like Figure 1 As shown, in this embodiment, the upper mold also includes a pressing device 4, which includes a pressing plate 41, which is arranged on the lower surface of the upper cutting plate 12 and is used to press the battery pole piece to be cut. During high-speed cutting, the battery pole piece may be offset due to factors such as vibration or airflow. The pressing plate 41 presses the pole piece to ensure its stable position during the cutting process, thereby avoiding cutting size errors caused by offset.

[0029] like Figure 4As shown, in this embodiment, the pressing device 4 also includes a reset spring 42, a second guide assembly 43 and a contour sleeve 44. The pressing plate 41 is arranged on the lower surface of the upper cutting plate 12. The pressing plate 41 can be lifted and lowered under the guidance of the second guide assembly 43. The second guide assembly 43 ensures that the pressing plate 41 remains vertical and stable during the lifting and lowering movement, preventing deviation and tilting, and further enhancing the accuracy of the pressing. The lower end of the contour sleeve 44 is connected to the pressing plate 41, and the upper end of the contour sleeve 44 is installed on the upper template 11. The contour sleeve 44 is used to limit the descending height of the pressing plate 41. The contour sleeve 44 connects the pressing plate 41 and the upper template 11, and strictly limits the descending height of the pressing plate 41. This means that during the cutting process, the pressure of the pressing plate 41 on the battery electrode is constant and controllable, thereby ensuring the accuracy and consistency of the cutting. The upper end of the return spring 42 abuts against the bottom of the upper cutting plate 12, and the lower end of the return spring 42 abuts against the pressing plate 41, and is used to drive the pressing plate 41 to return downward. The design of the return spring 42 enables the pressing plate 41 to return to its initial position quickly and accurately after each cutting. This not only improves production efficiency, but also reduces cutting errors caused by inaccurate position of the pressing plate 41.

[0030] The return spring 42 and the second guide assembly 43 work together to reduce the impact and vibration generated during the cutting process, which helps to extend the service life of the mold and the blade.

[0031] The contour sleeve 44 prevents overpressure on the battery pole piece by limiting the descending height of the pressing plate 41, thereby protecting the pole piece and the mold from damage.

[0032] In this embodiment, the pressing device 4 is an important component of the battery pole piece high-speed cutting die, and its main function is to press the battery pole piece to be cut during the cutting process to ensure the stability and accuracy of the cutting. The pressing device 4 in this embodiment not only has the basic pressing function, but also realizes the effective control of dust during the cutting process by integrating the dust removal device 5.

[0033] like Figure 5 As shown, the pressing device 4 further includes a dust removal device 5 , and the dust removal device 5 includes a dust removal cavity 51 , a dust removal air outlet 52 and a dust removal pipe 53 arranged in the pressing plate 41 .

[0034] The dust removal chamber 51 is cleverly arranged inside the pressing plate 41 to form a closed space for collecting and storing dust generated during the cutting process. The design of the dust removal chamber 51 takes into account the dust collection efficiency and storage capacity to ensure that dust can be continuously and effectively collected during a long cutting process.

[0035] The dust removal air intake port 52 is arranged on the side of the pressing plate 41 close to the upper cutter portion 121. The dust removal air intake port 52 is carefully arranged on the side of the pressing plate 41 close to the upper cutter portion 121. This position enables the air intake port to directly capture the dust generated by the upper cutter portion 121 during the cutting process and further remove the dust on the upper cutter portion when the upper cutter portion is reset upward through the dust removal air intake port 52. When the upper cutter portion 121 is cutting, the generated dust will be captured by the dust removal air intake port 52 and collected through the dust removal chamber 51. By removing the dust near the upper cutter portion 121, the dust removal device 5 reduces the risk of wear and damage to the upper cutter portion 121 caused by dust, and extends its service life. At the same time, the reduction of dust also improves the precision and quality of cutting, because the dust will not interfere with the cutting process.

[0036] The dust removal exhaust port 52 is connected to the dust removal chamber 51 to form a dust collection channel, ensuring that the dust can smoothly enter the dust removal chamber 51. The dust removal chamber 51 is connected to the dust removal pipe 53 to form a closed dust extraction system. The dust removal pipe 53 evacuates the dust removal chamber 51 to extract the dust in the dust removal chamber 51 and discharge it to the processing equipment outside the mold. The dust removal chamber 51 removes the dust from the upper cutting knife part 121 through the dust removal exhaust port 52.

[0037] like Figure 7 and Figure 8 As shown, in this embodiment, the dust removal air extraction port 52 includes a press plate extension 521 and a dust removal port cover 522, and the dust removal port cover 522 is detachably covered on the press plate extension 521 to form the dust removal air extraction port 52. The press plate extension 521 is a specific part of the press plate 41, which extends to one side and provides a mounting base for the dust removal port cover 522. The press plate extension 521 is used to ensure a close fit with the dust removal port cover 522 to form an effective air extraction channel. The dust removal port cover 522 is a detachable component, which covers the press plate extension 521 and together with the extension constitutes the dust removal air extraction port 52. The cover is detachable, which means that it can be easily removed when it needs to be cleaned or replaced.

[0038] like Fig. 9 As shown, in this embodiment, the bottom surface of the dust removal port cover 522 near the dust removal air extraction port 52 is provided with an inclined surface 5221, and the closer the inclined surface 5221 is to the dust removal air extraction port 52, the smaller the distance between the pressing plate extension portion 521. The design of the inclined surface 5221 helps to guide the airflow to enter the dust removal air extraction port 52 more smoothly. As the inclined surface 5221 gradually approaches, the airflow speed may increase slightly, thereby enhancing the ability of dust to be sucked into the dust removal system.

[0039] In this embodiment, the height of the dust removal air outlet 52 is smaller than the height of the dust removal chamber 51 .

[0040] like Figure 6 and Fig.10 As shown, in this embodiment, connection holes 411 are respectively provided on both sides of the pressing plate 41. When one of the connection holes 411 is used to connect the dust removal pipe 53, the other connection hole 411 is blocked with a plug 412. The hole position for connecting the dust removal pipe 53 is selected according to actual needs, so that the equipment layout is more flexible and can adapt to different working environments and process requirements.

[0041] like Fig.10 As shown, in this embodiment, a reinforcing rib 511 is vertically arranged in the dust removal chamber 51. In this embodiment, two reinforcing ribs 511 are arranged, and the reinforcing ribs 511 are used to support the upper wall of the dust removal chamber 51 and the lower wall of the dust removal chamber 51. Since the pressing plate 41 needs to be repeatedly lowered to press the battery pole piece, the upper wall and the lower wall of the dust removal chamber 51 will be subjected to continuous and periodic pressure. The provision of the reinforcing rib 511 can effectively enhance the structural stability of the dust removal chamber 51, resist such repeated pressure, and prevent the dust removal chamber 51 from deformation or rupture.

[0042] In this embodiment, the reinforcing rib 511 extends along the width direction X of the dust removal chamber 51. The reinforcing rib 511 extends along the width direction of the dust removal chamber 51, which helps to evenly distribute the pressure on the upper wall and the lower wall of the dust removal chamber 51. This distribution method enables the dust removal chamber 51 to maintain better stability and reduce the local stress concentration phenomenon when it is subjected to the pressure of the pressing plate 41 repeatedly descending and pressing the battery electrode sheet.
