Description

Technical Field

[0001] The present application relates to the field of battery pole piece cutting dies, and in particular to a dust removal support plate for a battery pole piece cutting dies. Background Art

[0002] In the manufacturing process of lithium batteries, the cutting of battery pole pieces is a crucial step. This step requires the use of a special cutting mold to accurately cut the coated and rolled pole piece materials to form a pole piece shape that meets the requirements. However, during the cutting process, a large amount of fine metal particles or dust will be generated due to the cutting of metal materials (such as aluminum foil or copper foil).

[0003] In the prior art, in order to control the spread of these dusts and maintain the cleanliness of the production environment, a method of opening dust removal slots on the lower mold plate and the lower mold bottom plate is generally adopted. These slots are located below the cutting area and are connected to the fan through pipes to form a negative pressure system. When the fan is started, negative pressure is generated in the dust removal slots, which attracts and extracts the surrounding dust, and then transports the dust to a dust collection device (such as a dust collector, dust bag, etc.) for centralized treatment.

[0004] However, although the prior art has solved the problem of dust diffusion to a certain extent, it still has significant shortcomings. First, when the dust falls from the cutting area, it is easy to accumulate in the gaps between the templates of the lower mold, especially under the support plate. Since the support plate needs to support the pole piece for lifting and lowering during the cutting process, there is a large gap between the support plate and the lower template, which provides conditions for the accumulation of dust. Secondly, since the dust removal grooves in the prior art are usually long, the dust removal effect near the cutting edge of the lower cutting knife is often poor, resulting in serious dust accumulation at the cutting edge, affecting the cutting accuracy and mold life. Utility Model Content

[0005] The purpose of this application is to provide a dust removal support plate for a battery pole piece cutting mold that can significantly improve the dust treatment efficiency during the battery pole piece cutting process, and effectively prevent dust from accumulating in the gaps between the templates of the lower mold, especially the dust accumulation problem under the support plate and at the cutting edge.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] A dust removal support plate is located on one side of a lower cutting knife, comprising a dust removal box and a hanging platform, wherein the dust removal box is mounted on the support plate and is adjacent to the blade of the lower cutting knife, the hanging platform is arranged on the side of the dust removal box and is located below the cutting area, and is used to receive dust falling from the cutting area, the dust removal box is provided with a dust removal through hole, and the dust removal box is connected to a dust removal fan, and the dust removal fan sucks away dust from the blade of the lower cutting knife, the cutting area and the hanging platform through the dust removal through hole of the dust removal box.

[0008] Furthermore, the side of the dust removal box body close to the lower cutting knife is a first side surface, and the first side surface is provided with multiple rows of dust removal through holes, and the dust removal through holes are connected to the dust removal cavity in the dust removal box body.

[0009] Furthermore, a dust collecting trough is formed between the hanging platform and the first side surface of the dust removal box, and the upper end of the dust collecting trough is a material collecting opening, and the material collecting opening corresponds to the cutting area.

[0010] Furthermore, a dust removal through hole is also provided in the dust collecting slot on the first side, and the dust generated in the cutting area enters the dust collecting slot through the collecting opening, and the dust removal through hole sucks away the dust in the dust collecting slot through the dust removal fan.

[0011] Furthermore, a dust collection narrowing slope is provided in the dust collecting groove, and the dust collection narrowing slope is used to guide the dust to gather toward the dust removal through hole.

[0012] Furthermore, the dust collecting narrowing slope is gradually inclined to the dust removal through hole close to the first side surface of the dust removal box body.

[0013] Furthermore, the dust collecting trough is funnel-shaped.

[0014] Furthermore, the dust removal box is made of a transparent material, and the transparent material facilitates observation of the dust situation in the dust removal box.

[0015] Furthermore, the dust removal through hole is a round hole, a square hole or other special-shaped holes.

[0016] The beneficial effects of this application are:

[0017] The present application realizes the rapid and effective removal of dust generated during the cutting process by installing a dust removal box and a hanging platform close to the cutting edge of the lower cutting knife. This design significantly improves the dust treatment efficiency, mainly due to the special position of the dust removal box and the synergistic effect of the hanging platform.

[0018] The dust removal box is located close to the cutting edge, ensuring that dust can be quickly captured the moment it is generated. The dust removal holes inside are connected to the dust removal fan. When the fan is started, a strong negative pressure suction force is generated through the dust removal holes. This negative pressure suction force can quickly suck the dust generated at the cutting edge and cutting area into the dust removal box.

[0019] At the same time, the hanging table is located below the cutting area, effectively catching the falling dust and playing a temporary collection role. When the dust falls on the hanging table, due to the negative pressure of the dust removal box, the dust is quickly sucked into the dust removal holes and then taken away by the dust removal fan.

[0020] This compact and efficient design ensures that dust can be quickly sucked away after it is generated, thereby greatly improving dust handling efficiency and reducing the residence time and diffusion possibility of dust in the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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.

[0031] like Figure 4As shown, during the working process of the battery electrode sheet cutting mold, the dust-removing support plate 3 is located on the lower mold 7 and is installed on one side of the lower cutting knife 4. When the upper mold 5 drives the upper cutting knife 52 to descend, it will first cooperate with the dust-removing support plate 3 through the upper pressing column 51 to press the battery electrode sheet. This step ensures the stability of the electrode sheet during the cutting process and prevents it from moving or tilting. After the electrode sheet is pressed, the upper cutting knife continues to descend and cooperates with the lower cutting knife 4 to perform the cutting operation. At this time, the area where the upper cutting knife and the lower cutting knife 4 act together is defined as the cutting area. The support plate 3 bears the task of supporting the electrode sheet during the cutting process. The dust-removing support plate 3 of this embodiment not only bears the function of supporting and stabilizing the electrode sheet, but also integrates the dust removal function. Its design helps to collect the dust generated during the cutting process and keep the cutting area clean, thereby improving the cutting quality and the service life of the mold.

[0032] like Figure 1 and Figure 4 As shown, a dust-removing supporting plate 3 is located on one side of the lower cutting knife 4, including a dust-removing box 1 and a hanging platform 2. The dust-removing box 1 is detachably mounted on the supporting plate 3 and is adjacent to the blade W of the lower cutting knife 4. The hanging platform 2 is arranged on the side of the dust-removing box 1 and is located below the cutting area E, and is used to receive the dust falling from the cutting area. The dust-removing box 1 is provided with a dust-removing through hole 11, and the dust-removing box 1 is connected to a dust-removing fan. The dust-removing fan absorbs the dust at the blade of the lower cutting knife 4 and the cutting area and the hanging platform 2 through the dust-removing through hole 11 of the dust-removing box 1. A dust-removing pipe 6 is arranged on the rear side of the dust-removing box for connecting with the dust-removing fan.

[0033] During the cutting process, the generated dust will fall. The function of the hanging table 2 is to receive the dust falling from the cutting area and play a temporary collection role. The dust removal box 1 is provided with dust removal holes 11, which are connected to the dust removal fan. When the dust removal fan is started, it will generate a strong suction force to suck away the dust at the edge of the lower cutting knife 4, the cutting area and the hanging table 2 through the dust removal holes 11. The sucked dust will then be transported to a dust collection device (such as a dust collector, dust bag, etc.) for centralized treatment, thereby keeping the working environment clean.

[0034] like Figure 4 and Figure 5As shown, in this embodiment, the side of the dust removal box 1 close to the lower cutting knife 4 is the first side 12, and the first side 12 is provided with multiple dust removal holes 11, and the dust removal holes 11 are connected to the dust removal chamber 13 in the dust removal box 1. By providing multiple dust removal holes 11, the effective area of ​​dust removal is actually increased. This means that the dust generated during the cutting process has more opportunities and a larger area to be captured and sucked away by the dust removal holes 11. This design not only improves the dust removal efficiency, but also ensures that a larger range of dust can be handled in time, thereby further reducing the diffusion and accumulation of dust in the working environment.

[0035] like Figure 4 and Figure 5 As shown, in this embodiment, a dust collecting trough 14 is formed between the hanging platform 2 and the first side surface 12 of the dust removal box 1, and the upper end of the dust collecting trough 14 is a collection opening 15, and the collection opening 15 corresponds to the cutting area. The main function of the dust collecting trough 14 is to collect dust generated during the cutting process. Since the collection opening 15 directly corresponds to the cutting area, the dust generated during cutting will naturally fall into the dust collecting trough 14, thereby preventing dust from overflowing.

[0036] The design of the dust collecting trough 14 helps prevent dust from spreading to other places in the working area and keeps the working environment clean. Dust enters the dust collecting trough 14 through the collecting opening 15 and is effectively controlled within a certain range without flying randomly.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the first side surface 12 is also provided with a dust removal through hole 11 in the dust collecting groove 14, and the dust generated in the cutting area enters the dust collecting groove 14 through the collecting opening 15, and the dust removal through hole 11 sucks away the dust in the dust collecting groove 14 through the dust removal fan. By providing the dust removal through hole 11 in the dust collecting groove 14, the dust in the groove can be sucked away more directly and efficiently. When the dust generated in the cutting area enters the dust collecting groove 14 through the collecting opening 15, the dust removal fan can quickly suck away the dust through the dust removal through hole 11, reducing the residence time of the dust in the dust collecting groove 14, thereby improving the dust removal efficiency.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, a dust collection narrowing slope 141 is provided in the dust collection groove 14, and the dust collection narrowing slope 141 is used to guide the dust to gather toward the dust removal through hole 11. The dust collection narrowing slope 141 can effectively guide the dust generated during the cutting process to gather toward the dust removal through hole 11, making it easier for the dust to be sucked away by the dust removal fan. This design reduces the dispersion of dust in the dust collection groove 14, thereby improving the efficiency and effect of dust removal.

[0039] In fluid dynamics, the design of the bevel or cone helps to reduce the generation of eddy currents. Eddy currents can cause energy loss and reduce the efficiency of the airflow. By narrowing the bevel, this unfavorable airflow pattern can be reduced, allowing the airflow to flow more smoothly to the dust removal through hole 11.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the dust collection narrowing slope 141 gradually slopes to the dust removal through hole 11 close to the first side surface 12 of the dust removal box 1. The narrowing slope is designed to be gradually narrowed, so as to guide the airflow to gradually accelerate and concentrate on flowing to the dust removal through hole 11. This design can reduce the turbulence of the airflow, make the airflow pass through the dust removal through hole 11 more orderly, and improve the dust collection efficiency.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, the dust collecting groove 14 is funnel-shaped. The funnel-shaped design helps the dust to flow to the bottom of the dust collecting groove 14 more smoothly under the action of gravity and airflow, and then be sucked away by the dust removal through hole 11. This shape can reduce the retention of dust in the groove, thereby improving the efficiency of dust removal.

[0042] like Figure 4 and Figure 5 As shown, in this embodiment, the dust removal box 1 is made of transparent material, which makes it easy to observe the dust situation in the dust removal box 1. By observing the dust situation in the dust removal box 1, the operator can judge when cleaning and maintenance are needed, avoiding unnecessary downtime and improving the use efficiency of the equipment.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the dust removal through hole 11 is a round hole or a square hole or other special-shaped holes.
