Description

Technical Field

[0001] This application relates to the field of stamping die technology, and in particular to a waste removal stamping die device, a waste removal method, and an electrode production system. Background Technology

[0002] Stamping is a common process in material production. For example, materials may include coiled or strip raw materials such as battery tabs. Stamping uses a die to cut the material into the desired shape. Waste removal is a crucial step in the stamping process; failure to remove waste generated during stamping will affect production efficiency and product quality.

[0003] Currently, existing waste removal methods typically involve blowing air downwards through the vents inside the punch, deforming the waste material and detaching it from the punch, allowing it to enter the suction area. In the suction area, negative pressure is used to draw the waste material away. However, this method can easily lead to deformation of the rounded corners formed after waste removal, thus affecting the quality of the material after cutting. Summary of the Invention

[0004] This application provides a waste discharge die, a waste discharge method, and an electrode production system, which can solve the problem of electrode deformation caused by waste discharge, thereby improving the electrode production quality.

[0005] In a first aspect, embodiments of this application provide a waste material discharge die device, the device comprising:

[0006] The lower mold assembly has a waste discharge channel and a first air inlet channel. The lower mold assembly also has a lower mold and a material support at the feeding end of the waste discharge channel. The lower mold has a connecting channel that connects with the waste discharge channel. The material support is attached to one side wall of the connecting channel and is located on one side of the waste discharge channel. The air outlet of the first air inlet channel is located on the side of the material support adjacent to the waste discharge channel and is connected to the connecting channel.

[0007] The upper mold assembly includes an upper mold and a bending member. The upper mold is movably disposed on top of the material support member, so that the lower mold has a closed mold position and an open mold position. When the upper mold is in the open mold position, it is located on top of the lower mold and a channel for material to pass through is provided between the upper mold and the lower mold. When the upper mold is in the closed mold position, it contacts the material support member and cooperates with the lower mold to cut the waste material in the material. The bending member is movably disposed inside the upper mold and is located on the side of the material support member adjacent to the waste discharge channel. The bending member is configured to move toward the material support member when the upper mold is in the closed mold position to press the waste material, so that a portion of the waste material bends toward the connecting channel and is opposite to the air outlet of the first air inlet channel.

[0008] This application provides a waste material discharge punching device. An upper die is movably mounted on top of a material support member, allowing the lower die to have a closed position and an open position. The upper die, in the closed position, cooperates with the lower die to cut waste material from the material. This allows the upper die to be moved to the closed position to remove waste material during cutting. After cutting, the upper die can be moved to the open position so that the waste material, after separating between the lower die and the material support member, enters the waste discharge channel through a connecting channel and is discharged to the outside of the waste material discharge punching device. Furthermore, since the material support is located on one side of the waste discharge channel and is in contact with the channel wall on one side of the connecting channel, the material support can support the material when the lower die is in the closed position to cut the material, and when the lower die is in the open position to allow the material to move along the channel between the lower die and the material support after being cut. This reduces the impact of negative airflow pressure on the rounded corners formed after the waste is removed, thereby preventing deformation of the rounded corners formed after the waste is removed, improving the quality of the material after cutting, and reducing the stamping cycle of the waste discharge die equipment.

[0009] Based on this, when the upper die is in the closed position, the bending member moves towards the material support member, pressing down the waste material. This causes the waste material to bend towards the connecting channel, with the bent portion positioned opposite the air outlet of the first air inlet channel. This allows the waste material to bend on one side of the material support member and form a consistent air-blowing force surface. Furthermore, since the air outlet of the first air inlet channel is located on the side of the material support member adjacent to the waste discharge channel and connected to the connecting channel, when airflow enters the waste discharge die equipment through the first air inlet channel, the airflow will be blown towards the air-blowing force surface of the waste material through the air outlet of the first air inlet channel. This allows the waste material to smoothly detach from the material support member and move towards the side of the connecting channel connected to the waste discharge channel, entering the waste discharge channel through the connecting channel and thus being discharged to the outside of the waste discharge die equipment. This ensures smooth waste discharge and helps reduce the maintenance frequency of the waste discharge die equipment.

[0010] In one possible implementation, the projection of the feed end of the waste discharge channel onto the connecting channel is located within the connecting channel.

[0011] In one possible implementation, the upper mold assembly further has a second air inlet channel, the air outlet of which is located on one side of the upper mold and is opposite to and in communication with the connecting channel.

[0012] In one possible implementation, the lower mold assembly further includes a waste discharge cylinder located on the side of the lower mold assembly opposite to the upper mold assembly and communicating with the waste discharge channel.

[0013] In one possible implementation, the second air intake passage has multiple air outlets.

[0014] In one possible implementation, the upper mold assembly further includes an upper mold base, a pressure plate, and a mounting plate. The upper mold base is located on the side of the upper mold facing away from the lower mold. The pressure plate and the mounting plate are stacked on the side of the lower mold base facing the lower mold assembly and are both arranged around the periphery of the lower mold. The mounting plate is located between the pressure plate and the upper mold base and is connected to the upper mold.

[0015] The air outlet of the second air intake channel is located on the pressure plate or the mounting plate.

[0016] In one possible implementation, the air inlet of the second air inlet channel is located on the upper mold base.

[0017] In one possible implementation, a drive member is also included, located on the side of the upper die assembly facing the lower die assembly, the middle portion of which is movably connected to the upper die assembly except for the upper die and the bending member;

[0018] The first end of the drive member is also movably connected to the bending member, and the second end of the drive member is configured to move toward or away from the lower die assembly to drive the bending member to move relative to the upper die.

[0019] In one possible implementation, the lower mold assembly has a support protrusion on the side facing the upper module;

[0020] The support protrusion is configured such that when the upper mold is in the mold closing position, it can contact the second end of the drive member to drive the first end of the drive member to move toward one side of the lower mold assembly, and simultaneously move the bending member.

[0021] In one possible implementation, the support protrusion is configured such that the upper mold does not contact the second end of the drive member when the upper mold is in the mold opening position.

[0022] In one possible implementation, a reset component is also included, which is disposed within the upper mold assembly and contacts the middle portion of the drive member;

[0023] The reset assembly is configured to drive the second end of the drive member toward one side of the lower die assembly after the waste material is pressed by the bending member.

[0024] In one possible implementation, the upper mold assembly has an installation space in the region corresponding to the middle of the drive member, and the reset assembly is disposed within the installation space.

[0025] In one possible implementation, the reset assembly includes an elastic element and a pusher element, both of which are disposed within the mounting space. A first end of the elastic element is fixed relative to the upper mold assembly, and a second end of the elastic element is connected to the pusher element. The end of the pusher element facing away from the elastic element abuts against the middle of the drive element.

[0026] The elastic element is configured to deform in the direction from its first end to its second end to drive the pusher to move toward or away from the lower mold assembly.

[0027] In one possible implementation, the reset assembly further includes a fixing member disposed within the mounting space and connected to a first end of the elastic member.

[0028] In one possible implementation, the first air intake channel has multiple air outlets.

[0029] In one possible implementation, the lower mold assembly further includes a lower mold base disposed on the side of the lower mold and the material support member opposite to the upper mold;

[0030] The air inlet of the first air intake channel is located on the lower mold base.

[0031] In one possible implementation, the material thickness is 4μm-20μm.

[0032] In a second aspect, the present invention provides a waste discharge method for a waste discharge die equipment, which is applied to the waste discharge die equipment as described in any of the above claims. The waste discharge die equipment has an upper die, a material support, a bending member, a connecting channel, a first air inlet channel, and a waste discharge channel. The upper die has an opening position and a closing position.

[0033] The waste disposal method includes the following steps:

[0034] 1) When the upper mold is in the mold opening position, the material is controlled to pass through the channel between the upper mold and the material support member at a preset step distance;

[0035] 2) Control the upper mold to move towards the material support member to the mold closing position to cut the waste material in the material;

[0036] 3) Control the bending member to move toward the material support member to press the waste material, so that part of the waste material bends toward the connecting channel;

[0037] 4) Control the upper mold to move toward the side away from the material support to the mold opening position, and control the bending part to move toward the side away from the material support;

[0038] 5) Blow air into the connecting channel through the first air inlet channel to make the waste material detach from the material support and move into the connecting channel, and then discharge it from the waste discharge channel through the connecting channel.

[0039] This application provides a waste removal method for a waste removal die equipment. In step 2), the upper die moves to the mold closing position towards the material support member. The waste removal setting allows the waste to support the material, reducing the impact of negative airflow pressure on the rounded corners formed after the waste is removed. This prevents deformation of the rounded corners formed after the waste is removed, improves the quality of the material after cutting, and reduces the stamping cycle of the waste removal die equipment. In step 3), the bending member presses down on the waste material, causing a portion of the waste material to bend towards the connecting channel. This allows the waste material to bend on one side of the material support and form a consistent air-blowing force surface. In step 4), after the upper die is moved to the die-opening position and the bending member moves away from the material support, in step 5), when the first air inlet channel blows air into the connecting channel, the airflow from the outlet of the first air inlet channel can blow towards the air-blowing force surface of the waste material. This allows the waste material to smoothly detach from the material support and move towards the side of the connecting channel that connects to the waste discharge channel. The waste material is then discharged from the waste discharge channel to the outside of the waste discharge die equipment, ensuring smooth waste discharge and reducing the maintenance frequency of the waste discharge die equipment.

[0040] In one possible implementation, the waste discharge die device further has a second air inlet channel, and after step 5), the waste discharge method further includes the following steps:

[0041] 6) Blow air into the connecting channel through the second air intake channel so that the waste material enters the waste discharge channel and is discharged.

[0042] Thirdly, the present invention provides an electrode production system, including a waste discharge punching device as described in any of the first aspects.

[0043] The electrode production system provided in this application has the same effect as the waste discharge die equipment provided in any embodiment of the first aspect of this application, namely, preventing the rounded corners formed after the material is cut off from deforming, improving the quality of the material after cutting and the stamping cycle of the waste discharge die equipment, ensuring the smooth discharge of waste, and reducing the maintenance frequency of the waste discharge die equipment.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] In the production process of material 300, stamping is a common process. Specifically, stamping uses a die to cut material 300 into the required shape. During the stamping process, scrap material 310 is generated. If the scrap material 310 is not removed in time, it will adversely affect the production quality and efficiency of material 300. Scrap removal technology is a key step in the stamping process, mainly used to handle the scrap material 310 generated after stamping.

[0062] Material 300 may include roll strip raw materials such as power battery electrode sheets (hereinafter referred to as electrode sheets), or material 300 may also include raw materials such as electronic component lead frames, precision hardware parts (such as mobile phone shielding covers, connectors, etc.) and flexible circuit boards.

[0063] The tab is a structural component of the electrode sheet, and its shape and dimensional accuracy are subject to extremely high precision. Tabs are typically formed by stamping and die-cutting the electrode sheet, and the electrode sheet thickness is usually less than or equal to 20 μm. Specifically, the tab thickness can typically range from 4 μm to 20 μm. For example, tab thicknesses can be 4.5 μm, 4.4 μm, 4.6 μm, etc.

[0064] It should be noted that the tab is part of the electrode sheet structure, and the thickness of the tab can also be understood as the thickness of the electrode sheet.

[0065] Because tabs are thin and flexible, they are easily deformed during the stamping process due to external forces or airflow. Therefore, the stability and precision of waste removal technology are extremely important in the production of tabs.

[0066] The following text mainly uses the tab as an example to further elaborate on the stamping process of material 300 and its related equipment.

[0067] like Figure 1 , Figure 2 and Figure 3 As shown, existing waste discharge die equipment typically includes an upper die assembly 200, a lower die assembly 100, and a waste discharge cylinder 160. Material 300 is located between the upper die 210 and the lower die 130. The upper die 210 moves towards the lower die 130, and when a portion of the upper die 210 moves into the connecting channel 150 of the lower die 130, it cooperates with the lower die 130 to cut the waste material 310. The lower die 130 has a cutting edge on the edge of the connecting channel 150, and the connecting channel 150 communicates with the waste discharge channel 110 within the waste discharge cylinder 160. The lower die 130 can be understood as a die with a through-hole (i.e., a cavity die). The lower die 130 also has a small structural component 190 in the middle of the through-hole. The structural component 190 is located within the through-hole and forms the connecting channel 150 with the inner wall of the through-hole. The upper die 210 has an exhaust hole, and the air outlet of the air blowing channel is connected to the exhaust hole. The airflow is discharged from the air outlet of the air blowing channel and enters the exhaust hole of the upper die 210, blowing towards the waste material 310. When the waste material 310 passes through the connecting channel 150, it is deformed by the airflow and the obstruction of the lower die 130 and the structural component 190, and detaches from the lower die 130. It then enters the waste discharge channel 110 in the waste discharge cylinder 160 through the connecting channel 150. After the stamping process cuts the waste material 310, a rounded corner 320 will be formed on the cut part of the material 300.

[0068] When material 300 is fed according to a preset step distance, the airflow blows directly onto material 300 as it passes through the area between upper die 210 and lower die 130. Due to the negative pressure of the airflow, material 300 undergoes severe deformation, especially the rounded corners 320. When the deformed material 300 moves within the area between upper die 210 and lower die 130, the rounded corners 320 are highly likely to come into contact with the cutting tool of lower die 130, further damaging material 300 and resulting in poor production quality after cutting.

[0069] To avoid poor production quality of material 300 after cutting, the common approach is to reduce the stamping speed. However, while reducing the stamping speed can decrease the deformation of material 300, it also reduces the production rate.

[0070] Furthermore, since the volume of the through-hole in the lower mold 130 is relatively fixed, when structural components are placed inside the through-hole, the diameter of the resulting connecting channel 150 becomes relatively small. When the waste material 310 separates from the lower mold 130 and enters the connecting channel 150, blockage of the waste material 310 can easily occur, resulting in poor waste discharge. This increases the frequency of maintenance, thereby reducing production efficiency and increasing production costs.

[0071] In summary, there is an urgent need for a more efficient and precise waste removal die-making equipment to optimize the waste removal process during the stamping of material 300, so as to avoid deformation of material 300, ensure that material 300 has high production quality after cutting, and improve production efficiency and reduce production costs.

[0072] In view of this, the present invention provides a waste discharge die device and a waste discharge method. The waste discharge die device is provided with a material support 140. The material support 140 can support the material 300 during the cutting and moving process to prevent the material 300 from deforming under the influence of airflow, especially the rounded corner 320, which can ensure that the material 300 has high production quality after cutting. Furthermore, the waste discharge die equipment is also equipped with a bending member 220, a first air inlet channel 120, a connecting channel 150, and a waste discharge channel 110. By moving the bending member 220 toward the material support member 140 and cooperating with the material support member 140, the waste material 310 can be partially bent, and a consistent air-blowing force surface can be formed on the waste material 310. This allows the airflow to be blown directly onto the air-blowing force surface of the waste material 310 through the air inlet of the first air inlet channel 120, so that the waste material 310 moves toward the side of the connecting channel 150 that connects with the waste discharge channel 110, and enters the waste discharge channel 110 through the connecting channel 150, thereby being discharged to the outside of the waste discharge die equipment. This ensures the smooth discharge of the waste material 310 and helps to reduce the maintenance frequency of the waste discharge die equipment.

[0073] The following description, in conjunction with the accompanying drawings and embodiments, will further elaborate on a waste material discharge die device provided in the embodiments of this application.

[0074] refer to Figure 1 , Figure 5 and Figure 6 As shown in the embodiment of this application, a waste material discharge punching device is provided, which includes an upper die assembly 200 and a lower die assembly 100.

[0075] The lower mold assembly 100 has a waste discharge channel 110 and a first air inlet channel 120. At the feed end of the waste discharge channel 110, the lower mold assembly 100 also has a lower mold 130 and a material support member 140. The lower mold 130 has a connecting channel 150, which communicates with the waste discharge channel 110. The material support member 140 is located on one side of the waste discharge channel 110 and fits against one side wall of the connecting channel 150.

[0076] The projection of the feed end of the waste discharge channel 110 onto the connecting channel 150 is located within the connecting channel.

[0077] The material support 140 is located on one side of the waste discharge channel 110 and is flush against the channel wall of the connecting channel 150, so that the material support 140 is in contact with one side of the channel wall of the connecting channel 150 while also being located on one side of the waste discharge channel 110. Specifically, the material support 140 can be located on one side of the waste discharge channel 110 along the movement direction of the material 300. The portion of the connecting channel 150 without the material support 140 is connected to the waste discharge channel 110.

[0078] The lower die 130, in cooperation with the upper die assembly 200, stamps the material 300, cutting the scrap 310 off the material 300 to form the desired shape. During the stamping process and as the material 300 moves within the scrap discharge die equipment, the material support 140 supports the material 300, and the scrap 310 rests on the material support 140. By providing the material support 140, deformation of the material 300 is reduced.

[0079] Specifically, the upper mold assembly 200 includes an upper mold 210 and a bending member 220. The upper mold 210 is movably disposed on top of the material support member 140 so that the lower mold 130 has a mold-closing position and a mold-opening position.

[0080] like Figure 5 As shown, Figure 5 The diagram shows that when the lower mold 130 is in the closed position and the upper mold 210 is in the open position, a channel is provided between the lower mold 130 and the material support 140 for the material 300 to pass through.

[0081] like Figure 6 As shown, Figure 6 The diagram shows that when the lower mold 130 is in the open position and the upper mold 210 is in the closed position, a portion of the upper mold 210 moves into the connecting channel 150 and cooperates with the lower mold 130 to cut the waste material 310 in the material 300, so that the waste material 310 is sandwiched between the material support 140 and the upper mold 210.

[0082] The distance between the upper mold 210 and the material support 140 can be adjusted by moving the upper mold 210. When the upper mold 210 is in the open position, the material 300 can move along the feeding direction X. When the upper mold 210 is in the closed position, the upper mold 210 directly acts on the material 300, applying pressure to the material 300, and cooperates with the lower mold 130 to cut the waste material 310 in the material 300. The material support 140 provides support force to the material 300.

[0083] It should be noted that, similar to the existing lower mold 130 mentioned above, the lower mold 130 in this embodiment also has a cutting edge on the edge of the connecting channel 150. The shape of the connecting channel 150 is the same as the shape that the material 300 needs to be cut, that is, the shape of the connecting channel 150 is the same as the shape of the waste 310. When the material support 140 is in contact with one side of the channel wall of the connecting channel 150, the side of the material support 140 facing the upper mold assembly 200 is lower than the side of the lower mold 130 facing the upper mold assembly 200, so that when the upper mold 210 is in the mold closing position, a portion of the upper mold 210 can be located within the connecting channel 150 to cooperate with the lower mold 130 in cutting the waste 310 in the material 300.

[0084] like Figure 5 and Figure 6 As shown, the bending member 220 is movably disposed within the upper die 210 and located on the side of the material support member 140 adjacent to the waste discharge channel 110. The bending member 220 is configured to move toward the material support member 140 when the upper die 210 is in the closed position to press the waste material 310, causing a portion of the waste material 310 to bend toward the connecting channel 150 and opposite the air outlet 121 of the first air inlet channel.

[0085] Specifically, such as Figure 7 As shown, when the upper mold 210 is in the closed position, the material 300 is sandwiched between the upper mold 210 and the material support member 140. The material support member 140 supports the waste material 310. Therefore, when the waste material 310 rests on the material support member 140, a portion of the waste material 310 is suspended near the connecting channel 150, and the bending member 220 is opposite to the suspended portion of the waste material 310 along the extending direction Y of the connecting channel. At this time, when the bending member 220 moves toward the material support member 140, it presses down on the suspended portion of the waste material 310, causing it to bend toward the connecting channel 150. Through the cooperation of the bending member 220 and the material support member 140, a portion of the waste material 310 is bent, and it is bent on one side of the material support member 140 to form a consistent air-blowing force surface, so that the airflow acts on the air-blowing force surface of the waste material 310, facilitating the discharge of the waste material 310.

[0086] Therefore, the waste discharge die device provided in this application embodiment has an upper die 210 movably disposed on top of the material support 140, so that the lower die 130 has a closed position and an open position. The upper die 210, when in the closed position, cooperates with the lower die 130 to cut the waste 310 in the material 300. This allows the upper die 210 to be moved to the closed position to remove the waste 310 from the material 300 during cutting. After cutting, the upper die 210 can be moved to the open position so that the waste 310, after separating between the lower die 130 and the material support 140, can enter the waste discharge channel 110 through the connecting channel 150 and be discharged to the outside of the waste discharge die device. Furthermore, since the material support 140 is located on one side of the waste discharge channel 110 and is in contact with the channel wall on one side of the connecting channel, the material support 140 can support the material 300 when the lower die 130 is in the closed position cutting the material 300, and when the lower die 130 is in the open position so that the material 300 moves along the channel between the lower die 130 and the material support 140 after being cut. This can reduce the influence of negative airflow pressure on the rounded corner 320 formed after the material 300 cuts the waste 310, thereby preventing the rounded corner 320 formed after the material 300 cuts the waste 310 from deforming, improving the quality of the material 300 after cutting and the stamping cycle of the waste discharge die equipment.

[0087] Based on this, when the upper mold 210 is in the mold closing position, the bending member 220 moves toward the material support member 140 to press the waste material 310, so that part of the waste material 310 bends toward the connecting channel 150. The bent part is set opposite to the air outlet 121 of the first air inlet channel, so that part of the waste material 310 can be bent on one side of the material support member 140 and form a consistent air blowing force surface, so that the airflow acts on the air blowing force surface of the waste material 310, which facilitates the discharge of the waste material 310.

[0088] In some embodiments of this application, the thickness of material 300 is less than or equal to 5 μm. For example, the thickness of material 300 can be 4.5 μm, 4.4 μm, 4.6 μm, etc. Considering the thin and flexible nature of material 300, this equipment can prevent material 300 from deforming after the removal of waste material 310 during the stamping process, especially preventing deformation of the rounded corners 320 of material 300, thereby achieving better production quality and higher production efficiency.

[0089] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the air outlet 121 of the first air inlet channel is located on the side of the material support 140 adjacent to the waste discharge channel 110 and is connected to the connecting channel 150.

[0090] Specifically, after stamping is completed, since the outlet 121 of the first air inlet channel is located on the side of the material support 140 adjacent to the waste discharge channel 110 and is connected to the connecting channel 150, when the airflow enters the waste discharge die equipment through the first air inlet channel 120, the airflow will be blown towards the blowing force surface of the waste 310 through the outlet 121 of the first air inlet channel, so that the waste 310 can smoothly detach from the material support 140 and move towards the side of the connecting channel 150 connected to the waste discharge channel 110, and enter the waste discharge channel 110 through the connecting channel 150, thereby being discharged to the outside of the waste discharge die equipment, ensuring the smooth discharge of the waste 310, which is conducive to reducing the maintenance frequency of the waste discharge die equipment.

[0091] Meanwhile, the first air inlet channel 120 has multiple air outlets. When the airflow enters the waste discharge die equipment through the first air inlet channel 120, the airflow is blown towards the blowing force surface of the waste 310 through the multiple air outlets of the first air inlet channel 120.

[0092] Multiple air outlets can convert the energy of the airflow into a stronger impact force, thus more effectively allowing the waste material 310 to detach smoothly from the material support 140 and move towards the side connected to the waste discharge channel 110 via the connecting channel 150. It then enters the waste discharge channel 110 via the connecting channel 150 and is discharged to the outside of the waste discharge die equipment. Multiple air outlets can shorten the waste discharge time, thereby improving production efficiency.

[0093] Furthermore, when some air outlets fail due to blockage or other problems, the other air outlets can continue to operate, reducing the number of maintenance operations and improving the overall reliability of the equipment.

[0094] In this application, the number of air outlets 121 in the first air inlet channel is not further limited. There can be one or more air outlets, such as two, four, five, six or eight, as long as they can allow the waste material 310 to smoothly detach from the material support member 140 and enter the waste discharge channel 110 through the connecting channel 150.

[0095] Furthermore, it should be noted that the first air intake channel 120 is embedded in the material support member 140. This application does not further limit the specific path of the first air intake channel 120 within the material support member 140, as long as the air outlet 121 of the first air intake channel is located on the side of the material support member 140 adjacent to the waste discharge channel 110 and is connected to the connecting channel 150, and the airflow acts on the blowing force surface of the waste material 310.

[0096] like Figure 5 and Figure 6As shown, in some embodiments of this application, the upper mold assembly 200 further includes a second air inlet channel 230. The air outlet 231 of the second air inlet channel is located on one side of the upper mold 210 and is opposite to and connected to the connecting channel 150. When the waste material 310 is blown into the connecting channel 150 by the airflow in the first air inlet channel 120, the airflow ejected from the air outlet 231 of the second air inlet channel flows along the direction extending from the connecting channel 150 to the waste discharge channel 110, and the airflow blows towards the waste material 310, assisting the waste material 310 to enter the waste discharge channel 110.

[0097] Therefore, when the waste material 310 enters the connecting channel 150, the second air intake channel 230 can provide an airflow that flows along the direction extending from the connecting channel 150 to the waste discharge channel 110. This airflow acts on the waste material 310, pushing it into the waste discharge channel 110, thereby ensuring that the waste material 310 enters the waste discharge channel 110 stably. This reduces the blockage of the waste material 310 in the connecting channel 150 and the waste discharge channel 110, improves production efficiency, reduces the maintenance frequency of the waste discharge die equipment, and lowers the production cost of the material 300.

[0098] Furthermore, since the waste material 310 can be smoothly discharged, the waste material discharge die equipment can be matched with a high-speed stamping cycle, thereby improving production efficiency. For example, through extensive testing, the stamping speed cycle of the waste material discharge die equipment in this embodiment of the application can be increased from 0.35 seconds / stroke to 0.25 seconds / stroke, resulting in an efficiency improvement of 28.57%.

[0099] Similarly, the second air intake channel 230 can also have multiple air outlets, and its principle is the same as that of the first air intake channel 120 having multiple air outlets, so it will not be described in detail here.

[0100] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the lower mold assembly 100 further includes a waste discharge cylinder 160, which is located on the side of the lower mold assembly 100 opposite to the upper mold assembly 200 and communicates with the waste discharge channel 110. The waste discharge cylinder 160 is used to contain waste material 310. Furthermore, a suction port can be provided at the end of the waste discharge cylinder 160 opposite to the end connected to the lower mold assembly 100. The suction port draws air from the waste discharge cylinder 160, achieving negative pressure adsorption within the waste discharge cylinder 160, thereby ensuring the smooth discharge of waste material 310.

[0101] like Figure 5 and Figure 6As shown, in some embodiments of this application, the upper mold assembly 200 further includes an upper mold base 240, a pressure plate 250, and a mounting plate 260. The upper mold base 240 is disposed on the side of the upper mold 210 facing away from the lower mold 130. The pressure plate 250 and the mounting plate 260 are stacked on the side of the upper mold base 240 facing the lower mold assembly 100, and are both arranged around the periphery of the upper mold 210. The mounting plate 260 is located between the pressure plate 250 and the upper mold base 240, and is connected to the upper mold 210.

[0102] During the stamping process, the stamping equipment moves the upper die holder 240 toward the lower die 130, and the mounting plate 260 moves the pressure plate 250 toward the lower die 130 together. Before the upper die 210 contacts the material 300, or when the upper die 210 contacts the material 300, the pressure plate 250 first presses down on the material 300. The upper die 210 continues to move toward the lower die 130, and the cutting is completed while the pressure plate 250 is pressing down on the material 300. During the process of the upper die assembly 200 returning to the open position, the stamping equipment moves the upper die holder 240 back up, thereby moving the mounting plate 260 and the upper die 210 toward the direction away from the lower die 130. During this process, the pressure plate 250 can still keep pressing down on the material 300. The upper die holder 240 continues to rise, the pressure plate 250 leaves the material 300, and the upper die holder 240 drives the mounting plate 260, the upper die 210 and the pressure plate 250 back to the die opening position, completing one stamping. The material 300 is transferred one step, ready for the next stamping.

[0103] The upper die assembly 200 has an upper die base 240, a pressure plate 250, and a mounting plate 260. The pressure plate 250 and the mounting plate 260 are stacked on the side of the upper die base 240 facing the lower die assembly 100 and are both arranged around the periphery of the upper die 210. The mounting plate 260 is located between the pressure plate 250 and the upper die base 240 and is connected to the upper die 210. The upper die base 240 provides a support platform for the pressure plate 250, the mounting plate 260, and the upper die 210, transmitting the movement of the stamping equipment to the pressure plate 250, the mounting plate 260, and the upper die 210, thus giving them higher structural stability and ensuring that the pressure plate 250, the mounting plate 260, and the upper die 210 do not shift during the stamping process, thereby improving the processing accuracy of the stamping process. The mounting plate 260 is used to fix and support the pressure plate 250 and the upper die 210 so that the pressure plate 250 and the upper die 210 can remain stable during the movement of the upper die base 240. The pressure plate 250 can press down on the material 300 before or simultaneously with the upper die 210 contacting the material 300. Furthermore, during the process of the upper die 210 returning to the open position, the pressure plate 250 can maintain the pressure on the material 300 until the upper die holder 240 continues to rise and the upper die 210 returns to the open position, so as to ensure that the material 300 remains fixed and stable during the stamping process.

[0104] The mounting plate 260 and the upper mold base 240 are rigidly connected by screws or bolts. The pressure plate 250 is connected to the mounting plate 260 by a spring, so that the pressure plate 250 can continue to press the material 300 when the upper mold base 240 rises.

[0105] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the air inlet of the second air inlet channel 230 is located on the upper mold base 240. The air outlet 231 of the second air inlet channel is located on the pressure plate 250 or the mounting plate 260. Specifically, when the side of the mounting plate 260 facing the lower mold 130 is not blocked by the pressure plate 250, the air outlet 231 of the second air inlet channel is located on the mounting plate 260. When the side of the mounting plate 260 facing the lower mold 130 is blocked by the pressure plate 250, the air outlet 231 of the second air inlet channel is located on the pressure plate 250, so that the air outlet 231 of the second air inlet channel is not blocked, ensuring that the airflow can be effectively discharged, blowing the waste 310 towards the waste discharge channel 110, thereby ensuring the smooth discharge of the waste 310.

[0106] Similarly, this application does not further limit the specific path of the second air intake channel 230 within the upper mold base 240 and mounting plate 260, or within the upper mold base 240, mounting plate 260 and pressure plate 250, as long as the airflow can blow towards the waste material 310 and assist the waste material 310 to enter the waste discharge channel 110.

[0107] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the waste discharge die device further includes a drive member 400. The drive member 400 is located on the side of the upper die assembly 200 facing the lower die assembly 100, and the middle portion 410 of the drive member is movably connected to the upper die assembly 200 except for the upper die 210 and the bending member 220. The first end 420 of the drive member is also movably connected to the bending member 220, and the second end 430 of the drive member is configured to be movable toward or away from the lower die assembly 100 to drive the bending member 220 to move relative to the upper die 210.

[0108] The connection point between the middle part 410 of the driving component and the upper die assembly 200 is the fulcrum for the rotation of the driving component 400. When the second end 430 of the driving component moves away from the lower die assembly 100, the first end 420 of the driving component moves towards the lower die assembly 100. The first end 420 of the driving component drives the bending component 220 to also move towards the side closer to the lower die assembly 100 until it contacts the scrap 310, bending the scrap 310. When the second end 430 of the driving component moves towards the side closer to the lower die assembly 100, the first end 420 of the driving component moves away from the lower die assembly 100, and the first end 420 of the driving component drives the bending component 220 to also move away from the lower die assembly 100, moving away from the scrap 310.

[0109] The drive component 400 is structurally connected to the upper die assembly 200 (excluding the upper die 210 and the bending component 220) via its middle portion 410. The movement of the second end 430 of the drive component can cause the first end 420 of the drive component to rotate around its middle portion 410. Specifically, the first end 420, the middle portion, and the second end of the drive component form a lever structure, changing the direction of force transmission. Furthermore, the drive component 400 directly controls the movement trajectory of the bending component 220, precisely driving it and ensuring that the bending component 220 reaches the same final position with each movement. This ensures that the bending component 220 presses the waste material 310 at the same bending angle, thereby improving the stability of the airflow blowing the waste material 310.

[0110] The middle portion 410 of the drive member can be hinged to the upper die assembly 200, excluding the upper die 210 and the bending member 220. For example, the side of the upper die base 240 facing the lower die assembly 100 can have a bracket, and the drive member 400 is hinged to the bracket via a pin. Similarly, the first end 420 of the drive member can also be hinged to the bending member 220.

[0111] Additionally, the middle portion 410 of the drive member refers to the central region of the drive member 400, excluding the ends. For example, in the length direction of the drive member 400, the midpoint of the drive member 400 is structurally connected to the upper die assembly 200, excluding the upper die 210 and the bending member 220.

[0112] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the lower mold assembly 100 has a support protrusion 170 on the side facing the upper mold assembly 200. The support protrusion 170 is configured to contact the second end 430 of the drive member when the upper mold 210 is in the closed position, so as to drive the first end 420 of the drive member to move toward one side of the lower mold assembly 100 and simultaneously move the bending member 220. The support protrusion 170 is configured not to contact the second end 430 of the drive member when the upper mold 210 is in the open position.

[0113] When the upper die 210 is in the closed position, the pressure plate 250 presses the material 300, and the support protrusion 170 contacts the second end 430 of the drive component. The support protrusion 170 provides a force to the second end 430 of the drive component away from the lower die 130. Since the middle of the drive component 400 is movably connected to the upper die assembly 200, this force drives the drive component 400 to rotate around the connection point, and the first end 420 of the drive component moves towards the lower die 130 until the scrap 310 is partially bent. By providing a force to the drive component 400 through the support protrusion 170, the bending component 220 can be driven to move without the need for an additional power source to drive the bending component 220, thereby reducing production costs.

[0114] The support protrusion 170 can be integrally formed with the lower mold assembly 100, or it can be installed on the side of the lower mold assembly 100 facing the upper mold assembly 200 by welding, bolting, or other methods. This application does not further limit the connection relationship between the support protrusion 170 and the lower mold assembly 100; the support protrusion 170 only needs to provide force to the drive component 400 when the upper mold 210 is in the closed position.

[0115] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the waste discharge die device further includes a reset assembly 500, which is disposed within the upper die assembly 200 and contacts the middle portion 410 of the drive member. The reset assembly 500 is configured to drive the second end 430 of the drive member to move toward one side of the lower die assembly 100 after the bending member 220 presses the waste 310.

[0116] The middle part 410 of the driving member refers to the middle region of the driving member 400. For example, the middle part 410 of the driving member can be the part of the driving member 400 near the second end or the part of the driving member 400 near the first end.

[0117] For example, the middle portion 410 of the drive member is the part of the drive member 400 near the second end. When the upper die assembly 200 rises, the second end 430 of the drive member separates from the support protrusion 170. The reset assembly 500 contacts the part of the drive member 400 near the second end, providing a force to the second end 430 of the drive member in the direction of the lower die assembly 100. The drive member 400 rotates about the connection point, driving the first end 420 of the drive member to move away from the lower die assembly 100. The first end 420 of the drive member drives the bending member 220 to move away from the lower die assembly 100, thereby causing the bending member 220 to leave the scrap 310 and return to its original position in time, avoiding deformation of the material 300 due to obstruction of the stamping of new material 300, and improving the production quality and efficiency of the material 300.

[0118] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the upper mold assembly 200 has an installation space 270 in the region of the middle part 410 of the corresponding drive member, and the reset assembly 500 is disposed in the installation space 270.

[0119] The reset assembly 500 includes an elastic element 510 and a pusher 520, both disposed within the mounting space 270. The first end of the elastic element 510 is fixed relative to the upper mold assembly 200, and the second end of the elastic element 510 is connected to the pusher 520. The end of the pusher 520 facing away from the elastic element 510 abuts against the center 410 of the drive member. The elastic element 510 is configured to deform in the direction from its first end to its second end, thereby driving the pusher 520 to move towards or away from the lower mold assembly 100.

[0120] When the second end 430 of the driving member is subjected to a force from the support protrusion 170 in a direction away from the lower die 130, the elastic element 510 is compressed, and the pushing element 520 moves away from the lower die 130. When the second end 430 of the driving member leaves the support protrusion 170, the elastic element 510 resets, providing a force closer to the lower die assembly 100. This force acts on the pushing element 520, which pushes the second end 430 of the driving member closer to the lower die 130. The first end 420 of the driving member rotates around the central connection point and moves away from the lower die 130, thereby driving the bending member 220 back to its original position. Through the cooperation of the elastic element 510 and the pushing element 520, the smoothness and precision of the movement of the bending member 220 are ensured, thereby maintaining the consistency and accuracy of the bending of the scrap 310 by the bending member 220.

[0121] For example, the upper mold base 240 may have a mounting hole in the region corresponding to the drive member 400, and the elastic member 510 and the pusher member 520 may be mounted in the mounting hole. The elastic member 510 may be a spring, which may engage with one end of the mounting hole away from the drive member 400, and the other end of the spring may be connected to the pusher member 520. The pusher member 520 may be a "T"-shaped rod.

[0122] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the reset assembly 500 further includes a fixing member 530, which is disposed within the mounting space 270 and connected to the first end of the elastic member 510. Specifically, the fixing member 530 may be a nut or screw, etc. Exemplarily, the screw is connected to the first end of the elastic member 510 to fix the elastic member 510 within the mounting space 270, providing support for the elastic member 510 and the pusher 520.

[0123] like Figure 5 and Figure 6As shown, in some embodiments of this application, the lower die assembly 100 further includes a lower die base 180, which is disposed on the side of the lower die 130 and the material support member 140 opposite to the upper die 210. The air inlet of the first air inlet channel 120 is disposed on the lower die base 180. The lower die base 180 provides support for the lower die 130 and the material support member 140, which can disperse the stamping force during the stamping process and improve the stability of the equipment.

[0124] In addition, the waste material discharge punching device provided in this application embodiment can adjust the parameters of its upper die assembly 200 and lower die assembly 100 according to the requirements of different product specifications, thereby meeting the needs of different products.

[0125] This application embodiment also provides a waste discharge method for a waste discharge die equipment (hereinafter referred to as the waste discharge method). The waste discharge method can be applied to the waste discharge die equipment in any of the above embodiments. The waste discharge die equipment has an upper die 210, a material support 140, a bending member 220, a connecting channel 150, a first air inlet channel 120 and a waste discharge channel 110. The upper die 210 has an open die position and a closed die position.

[0126] The steps of the waste disposal method are further explained below with reference to the accompanying drawings. (Reference) Figure 4 The waste disposal method includes the following steps:

[0127] Step 1) When the upper mold 210 is in the mold opening position, control the material 300 to pass through the channel between the upper mold 210 and the material support 140 at a preset step distance.

[0128] Step 2) Control the upper mold 210 to move toward the side of the material support 140 to the mold closing position to cut the waste material 310 in the material 300.

[0129] Step 3) Control the bending member 220 to move toward the material support member 140 to press the waste material 310, so that part of the waste material 310 bends toward the connecting channel 150.

[0130] Step 4) Control the upper mold 210 to move to the mold opening position on the side away from the material support 140, and control the bending part 220 to move on the side away from the material support 140.

[0131] Step 5) Blow air into the connecting channel 150 through the first air intake channel 120 so that the waste material 310 is detached from the material support 140 and moves into the connecting channel 150, and is discharged from the waste discharge channel 110 through the connecting channel 150.

[0132] Through steps 1) and 2), the stamping equipment drives the upper die 210 to the open position, forming a channel between the upper die 210, the lower die 130, and the material support 140, allowing the material 300 to be transported through this channel. The stamping equipment drives the upper die 210 to move towards the material support 140. When it moves to the closed position, the upper die 210 contacts the material support 140, cutting the waste material 310 in the material 300.

[0133] Through steps 3) and 4), the bending member 220 cooperates with the material support member 140 to press the waste material 310, so that part of the waste material 310 bends toward the connecting channel 150 to form an air-blowing force surface, which facilitates the airflow to push the waste material 310 into the connecting channel 150, thereby allowing the waste material 310 to enter the waste discharge channel 110.

[0134] In step 5), since the first air inlet channel 120 is located on the side of the material support 140 adjacent to the waste discharge channel 110 and connected to the connecting channel 150, air is blown into the connecting channel 150, causing the waste material 310 to detach from the material support 140 and enter the connecting channel 150, and then fall into the waste discharge channel 110. The airflow acts on the bent part of the waste material 310, avoiding the airflow acting on the processed material 300 and the unprocessed material 300, thereby reducing the deformation of the material 300.

[0135] Therefore, the waste removal method of the waste removal die equipment provided in this application embodiment, by moving the upper die 210 toward the material support member 140 to the die closing position in step 2), and setting the waste 310 to be cut, enables the material support member 140 to support the material 300, which can reduce the influence of airflow negative pressure on the rounded corner position formed after the waste 310 is cut off, thereby preventing the material 300 from deforming at the rounded corner position formed after the waste 310 is cut off, improving the quality of the material 300 after cutting and the stamping cycle of the waste removal die equipment. In step 3), the bending member 220 presses down on the waste material 310, causing a portion of the waste material 310 to bend towards the connecting channel 150. This allows a portion of the waste material 310 to bend on one side of the material support member 140 and form a consistent air-blowing force surface. In step 4), after the upper die 210 is moved to the die-opening position and the bending member 220 moves away from the material support member 140, in step 5), when the first air inlet channel 120 blows air into the connecting channel 150, the airflow output from the outlet 121 of the first air inlet channel can blow towards the air-blowing force surface of the waste material 310. This allows the waste material 310 to smoothly detach from the material support member 140 and move towards the side of the connecting channel 150 that connects with the waste discharge channel 110, and be discharged from the waste discharge channel 110 to the outside of the waste discharge die equipment. This ensures the smooth discharge of the waste material 310 and helps reduce the maintenance frequency of the waste discharge die equipment.

[0136] In some embodiments of this application, the waste discharge die device further includes a second air inlet channel 230, and after step 5, the waste discharge method further includes the following steps:

[0137] Step 6: Blow air into the connecting channel 150 through the second air intake channel 230 so that the waste material 310 enters the waste discharge channel 110 for discharge.

[0138] In step 6, the second air intake channel 230 discharges air into the connecting channel 150. The airflow acts on the waste material 310, assisting the waste material 310 into the waste discharge channel 110. This avoids the waste material 310 from blocking the waste discharge channel 110, thereby reducing the frequency of equipment maintenance, improving production efficiency, and reducing production costs.

[0139] This application also provides an electrode production system, which includes a waste discharge die device as described in any of the above embodiments.

[0140] For example, the system may include equipment for producing material 300 and a waste removal die. The equipment for producing material 300 is used to produce uncut material 300. For example, the equipment for producing material 300 may be a coating device, and the uncut material 300 may be an uncut electrode sheet. Specifically, the coating device can uniformly coat an active material slurry (such as lithium cobalt oxide / lithium iron phosphate for the positive electrode and graphite for the negative electrode) onto a metal current collector foil to obtain an uncut electrode sheet. After the waste is removed by the waste removal die, the uncut electrode sheet has tabs of the desired shape.

[0141] Since the electrode production system includes the waste discharge die equipment of any of the embodiments above, it has the same effects as the waste discharge die equipment, namely, preventing the material 300 from deforming at the rounded corner after the waste 310 is cut off, improving the quality of the material 300 after cutting and the stamping cycle of the waste discharge die equipment, ensuring the smooth discharge of the waste 310, and reducing the maintenance frequency of the waste discharge die equipment.
