Description

Technical Field

[0001] This utility model relates to the technical field of battery production equipment, and in particular to a waste collection device and an electrode cutting machine. Background Technology

[0002] In battery production, an electrode cutting machine is usually required. The electrode cutting machine cuts the metal foil in strip form and the separator together into electrodes with specific shapes.

[0003] Meanwhile, the cutting process also generates waste, which falls into the waste collection port and then enters the waste collection box.

[0004] The electrode cutting machine is equipped with a waste collection shell, which is located at the top of the waste collection box. The waste collection shell is open from top to bottom, with the top of the waste collection shell forming a waste collection port and the bottom of the waste collection shell connecting and communicating with the waste collection box.

[0005] The waste collection shell has inclined walls, which reduce the cross-sectional area of ​​the waste collection shell from top to bottom. Therefore, on the one hand, the size of the waste collection opening can be increased, making it easier to collect waste and guide it into the waste collection box. On the other hand, the opening connecting to the waste collection box can be reduced, so as not to affect the setting of the waste collection box.

[0006] However, cutting the electrode plates will cause the waste to become statically charged, causing the waste to adhere to the waste collection port, especially to accumulate on the inclined wall, resulting in waste accumulation and easy blockage of the waste collection port. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a waste collection device that can smoothly guide waste from the waste collection port into the waste collection box, avoiding waste blockage of the waste collection port.

[0008] This utility model also proposes an electrode cutting machine with the above-mentioned waste collection device.

[0009] The waste collection device according to a first aspect embodiment of the present invention includes:

[0010] Waste collection port;

[0011] The first separation mechanism includes a first blowing element, which is disposed at the waste collection port and is used to blow waste from the waste collection port into the interior of the waste collection port.

[0012] The waste collection device according to the embodiments of this utility model has at least the following beneficial effects:

[0013] This utility model incorporates a first separation mechanism, which includes a first blowing element. Therefore, when waste falls into the waste collection port, the first blowing element can blow the waste into the interior of the waste collection port, preventing waste from accumulating, blocking, or even overflowing, thus avoiding the hazards caused by waste accumulation, blockage, or overflow.

[0014] Since waste collection shells are often designed with inclined walls to increase the waste collection opening, when waste adheres to the inclined walls of the waste collection shell due to static electricity, the static electricity and friction make the waste easier to accumulate. However, this utility model, by setting a first blowing element, can release airflow to blow away the waste on the one hand, and on the other hand, the airflow can also perform electrical exchange to eliminate static electricity, making the waste easier to move and avoiding clogging the waste collection opening.

[0015] By incorporating a first blowing element, this invention also avoids generating heat on the waste material, thus preventing the waste material from heating up and causing a fire.

[0016] By setting a first blowing element, this utility model also reduces the force exerted on the external environment, preventing the equipment from shaking and affecting its operation. When applied to an electrode cutting machine, it does not affect the cutting accuracy of the electrode.

[0017] When applied to electrode cutting machines, waste can be removed in a timely manner to prevent waste from accumulating and coming into contact with the products produced during cutting, thus avoiding contamination of the electrode.

[0018] When applied to an electrode cutting machine, the first blowing element can release airflow, which can have a protective function or a heat exchange function, or the airflow can have both a protective function and a heat exchange function.

[0019] For example, the airflow can be a protective gas, such as an inert gas. A protective gas can reduce the oxygen content around the waste, thereby reducing the risk of fire caused by the oxidation of the metal foil due to heating.

[0020] For example, the airflow can be a heat exchange gas, such as helium in an inert gas. By flowing along the waste, the heat exchange gas can enhance heat exchange, reduce the temperature of the waste, reduce the activity of the metal foil, reduce the rate or probability of oxidation reaction, and further reduce the risk of fire.

[0044] The waste collection device and electrode cutting machine according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] Reference Figure 1 The present invention aims to provide an embodiment of an electrode cutting machine.

[0046] In this embodiment, the electrode cutting machine includes an electrode strip conveying device, an electrode cutting device, a waste removal device, and a waste collection device.

[0047] The electrode strip conveying device includes several conveying rollers, which convey the electrode strip in a taut manner. Figure 1 In the diagram, the conveying direction of the electrode strip is perpendicular to the viewing direction. The electrode strip includes metal foil and a diaphragm covering the metal foil.

[0048] The electrode cutting device includes a diaphragm clamp 230, which can fix the position of the electrode strip for easy and precise cutting.

[0049] The waste removal device includes a waste clamp 240 and a movable seat. The moving direction of the movable seat is perpendicular to the conveying direction of the electrode strip. The movable seat drives the waste clamp 240 to move. The waste clamp 240 can clamp the waste. Then, when the waste moves to the top of the waste collection device, the waste clamp 240 releases the waste, and the waste falls into the waste collection device.

[0050] Reference Figure 1 The present invention aims to provide an embodiment of a waste collection device, which may be part of an electrode cutting machine. Therefore, the present invention also aims to provide an embodiment of an electrode cutting machine that includes a waste collection device.

[0051] Compared with the prior art, the waste collection device of this utility model can smoothly guide the waste from the waste collection port 100 into the waste collection box 150, avoiding clogging of the waste collection port 100. Simultaneously, the electrode cutting machine of this utility model, by applying the above-mentioned waste collection device, can avoid waste accumulation and overflow, reduce the probability of waste contacting the electrode, prevent contamination of the electrode and even the battery, and keep the waste away from the cutting position, preventing the waste from being heated and ignited, thus avoiding fire, and also preventing the waste from interfering with the normal operation of the electrode cutting machine.

[0052] In this embodiment, the waste collection device mainly includes a waste collection shell 140, a waste collection box 150, a waste channel 170 connecting the waste collection box 150 and the waste collection shell 140, and also includes a first separation mechanism and a second separation mechanism.

[0053] The waste collection shell 140, waste channel 170 and waste collection box 150 are arranged sequentially from top to bottom to facilitate the waste to fall into the waste collection box 150 by its own gravity.

[0054] In this embodiment, the waste collection shell 140 is vertically continuous, and the top of the waste collection shell 140 is used to form a waste collection port 100. The waste collection port 100 gradually narrows from top to bottom to meet the needs of connecting the waste channel 170 and the waste collection box 150. At the same time, it makes the diameter of the waste channel 170 smaller, reducing the space occupied and facilitating the arrangement and connection.

[0055] In some specific embodiments of this utility model, the waste collection shell 140 can have two inclined walls 160 and two vertical walls, wherein the two vertical walls are located in the width direction of the waste collection port 100, which meets the spatial arrangement requirements of the electrode cutting machine. At the same time, it does not affect or reduce the discharge port of the waste collection shell 140, and facilitates the vertical falling of waste.

[0056] The two inclined walls 160 are arranged along the conveying direction of the electrode sheet, which can increase the specifications along the extension direction of the electrode sheet material strip and increase the length of the waste collection port 100, making it convenient to collect waste from different positions. At the same time, the inclined walls 160 also facilitate waste collection. Moreover, there is no need to increase the discharge port of the waste collection shell 140, and it does not affect the arrangement of the waste channel 170 and the waste collection box 150.

[0057] The second separation mechanism includes a second blowing element 190, which is located above the waste collection port 100. The second blowing element 190 is used to blow towards the waste generation point to remove the heat from the waste generation point, reduce the temperature of the waste, reduce the risk of the waste being oxidized or even burned by heat, and improve safety.

[0058] In some specific embodiments of this utility model, the second blowing element 190 may include a second blowing opening 200 and a third blowing opening 210. The second blowing opening 200 is used to blow waste material, and the third blowing opening 210 is used to blow the product, that is, to blow the electrode sheet.

[0059] exist Figure 1 In the diagram, the left-hand arrow indicates the blowing direction of the third blowing opening 210, and the right-hand arrow indicates the blowing direction of the second blowing opening 200.

[0060] Specifically, the second blowing opening 200 blows towards the waste material clamp 240, while the third blowing opening 210 blows towards the diaphragm clamp 230.

[0061] It is easy to understand that by setting the second blowing opening 200, this embodiment can continuously cool the waste material, further reducing the temperature of the waste material. At the same time, it helps to reduce static electricity and reduce the probability of waste material accumulating at the waste collection opening 100.

[0062] Furthermore, by setting a third blowing opening 210, this utility model can also cool down the electrode product and facilitate the removal of debris generated during cutting, thus avoiding affecting the quality of the electrode.

[0063] Reference Figure 1 and Figure 2 In some specific embodiments of this utility model, the second blowing element 190 may include a second blowing pipe, which is provided with a second blowing opening 200 and a third blowing opening 210. The blowing directions of the second blowing opening 200 and the third blowing opening 210 are different to meet the needs of blowing waste material and blowing electrode sheet.

[0064] Meanwhile, the second blowing component 190, which adopts the form of a blowing pipe, occupies little space and has a large blowing range.

[0065] In addition, by extending the blowing pipe and increasing the size of the material along the conveying direction of the electrode sheet, the blowing area can be enlarged, making it easier to blow material onto various parts of the electrode sheet and waste material. Moreover, it helps to extend the blowing time of the electrode sheet, allowing the electrode sheet to cool down sufficiently.

[0066] In some specific embodiments of this utility model, the second blowing opening 200 and the third blowing opening 210 can include multiple blowing holes 220, which can both meet the blowing needs and reduce the air output, thus satisfying the blowing needs of the two blowing openings.

[0067] Moreover, the blowing force of each blowing hole 220 is uniform and consistent. At the same time, multiple blowing holes 220 can enhance the connection strength at the blowing opening, which helps to maintain the strength of the second blowing tube and reduce blowing vibration and blowing noise.

[0068] In some specific embodiments of this utility model, the second separation mechanism may include a bracket, the bracket having a clamp for accommodating the end of the second blowing pipe, the clamp being provided with a locking bolt, the size of the clamp can be changed by rotating the locking bolt, which can simplify the installation of the second blowing pipe and facilitate the adjustment of the blowing direction.

[0069] In some specific embodiments of this utility model, the second separation mechanism may include multiple second blowing pipes to supply air separately, so as to avoid the blowing air volume being limited by the diameter of the air passage pipe.

[0070] In some specific embodiments of this utility model, the second blowing element 190 may include a blowing nozzle, which can be easily adjusted by changing the direction and position of the blowing nozzle to meet the needs of practical applications.

[0071] Reference Figure 3 and Figure 4 The first separation mechanism includes a first blowing element 110, which is disposed at the waste collection port 100 and is used to blow waste from the waste collection port 100 into the interior of the waste collection port 100.

[0072] In summary, this embodiment provides a first separation mechanism, which includes a first blowing element 110. Therefore, when waste falls into the waste collection port 100, the first blowing element 110 can blow the waste into the interior of the waste collection port 100, thus preventing waste from accumulating, blocking, or even overflowing, and avoiding the hazards caused by waste accumulation, blockage, or overflow.

[0073] Since the waste collection shell 140 is provided with inclined walls 160 to increase the waste collection port 100, when the waste adheres to the inclined walls 160 of the waste collection shell 140 due to static electricity, the static electricity and friction make the waste easier to accumulate. However, by providing the first blowing element 110, the present invention can release airflow, which can blow away the waste on the one hand, and on the other hand, the airflow can also perform electrical exchange to eliminate static electricity, making the waste easier to move and avoiding clogging the waste collection port 100.

[0074] It is easy to understand that by setting the first blowing element 110, this embodiment also avoids generating heat on the waste material, thus preventing the waste material from heating up and causing a fire.

[0075] It is easy to understand that by setting the first blowing element 110, this embodiment also reduces the force on the outside and avoids the equipment shaking and affecting the operation. When applied to the electrode cutting machine, it does not affect the cutting accuracy of the electrode.

[0076] When applied to electrode cutting machines, waste can be removed in a timely manner to prevent waste from accumulating and coming into contact with the products produced during cutting, thus avoiding contamination of the electrode.

[0077] When applied to an electrode cutting machine, the first blowing element can release airflow, which can have a protective function or a heat exchange function, or the airflow can have both a protective function and a heat exchange function.

[0078] For example, the airflow can be a protective gas, such as an inert gas. A protective gas can reduce the oxygen content around the waste, thereby reducing the risk of fire caused by the oxidation of the metal foil due to heating.

[0079] For example, the airflow can be a heat exchange gas, such as helium in an inert gas. By flowing along the waste, the heat exchange gas can enhance heat exchange, reduce the temperature of the waste, reduce the activity of the metal foil, reduce the rate or probability of oxidation reaction, and further reduce the risk of fire.

[0080] In some specific embodiments of this utility model, the heat exchange gas can be made to have a low temperature. Based on convective heat exchange, the heat exchange is enhanced by generating a temperature difference, thereby improving the cooling effect.

[0081] In some specific embodiments of this utility model, the first separation mechanism and the second separation mechanism can be equipped with ion fans to eliminate static electricity and facilitate the movement of waste materials.

[0082] In some specific embodiments of this utility model, the first blowing element 110 may include a first blowing tube, the first blowing tube being radially provided with a first blowing opening 120, the first blowing opening 120 having a length direction, and the length direction of the first blowing opening 120 being arranged along the axial direction of the first blowing tube.

[0083] It is easy to understand that by setting the first blowing pipe in this embodiment, the space occupied can be reduced, and it is convenient to arrange it inside the waste collection shell 140. This allows for blowing material closer to the waste, increasing the blowing force, while eliminating the need to increase the blowing volume.

[0084] It is easy to understand that in this embodiment, the first blowing opening 120 has a length direction. The length direction of the first blowing opening 120 is arranged along the axial direction of the first blowing pipe, which can increase the blowing area and facilitate blowing all the waste on a certain side wall of the waste collection shell 140, thereby reducing the blowing blind area.

[0085] Moreover, it allows for easy blowing of air at various locations on the waste material, increasing the blowing force and making it easier to blow larger pieces of waste.

[0086] Moreover, the first blowing opening 120 has a length direction, and the length direction of the first blowing opening 120 is arranged along the axial direction of the first blowing tube, which makes it easy to implement on the blowing tube and reduces the manufacturing difficulty.

[0087] In some specific embodiments of this utility model, the cross-section of the first blowing tube can be polygonal.

[0088] It is easy to understand that by making the cross-section of the first blowing tube polygonal, such as triangular, quadrilateral, or hexagonal, the strength of the first blowing tube can be improved. At the same time, it is convenient to process the first blowing opening 120, and the dimensional accuracy of the first blowing opening 120 can be improved, reducing the impact of manufacturing errors.

[0089] In some specific embodiments of this utility model, a number of installation connection points 130 may be provided at one end of the first blowing pipe.

[0090] It is easy to understand that in this embodiment, by setting a number of installation connection points 130, the first blowing pipe can be fixed by clamping the shell wall of the waste collection shell 140.

[0091] When there are two or more installation connection points 130 at one end of the first blowing pipe, it is also convenient to adjust and fix the orientation of the first blowing opening 120 on the first blowing pipe to meet the blowing requirements.

[0092] In some specific embodiments of this utility model, the installation connection point 130 can be an air connector to meet the need for air to be supplied into the first blowing pipe.

[0093] In some specific embodiments of this utility model, the waste collection shell 140 may be provided with an opening to allow the installation of the connection point 130 connecting bolts or the opening overlapping the waste collection shell 140, thereby meeting the installation requirements.

[0094] In some specific embodiments of this utility model, the first blowing element 110 can be disposed on the top of the inclined wall 160. The first blowing element 110 is used to blow the waste material on the inclined wall 160, thereby selectively blowing away the waste material on the inclined wall 160 and overcoming the problem that waste material is easy to accumulate on the inclined wall 160.

[0095] In some specific embodiments of this utility model, the number of first blowing elements 110 can be two, so that each inclined wall 160 is equipped with one first blowing element 110 to remove waste material on each inclined wall 160, thus meeting the actual needs.

[0096] In some specific embodiments of this utility model, the vertical wall may also be equipped with a first blowing element 110 to remove waste material in the form of debris adhering to the vertical wall.

[0097] In some specific embodiments of this utility model, the waste channel 170 can be a vertical channel extending up and down to avoid waste clogging in the smaller part of the channel. Since the waste channel 170 connects the small end of the waste collection shell 140 and the opening on the waste collection box 150, the diameter or cross-sectional area of ​​the waste channel 170 is relatively small.

[0098] In some specific embodiments of this utility model, the waste collection device may also include a waste detection sensor 180, which is used to detect waste in the waste channel 170 to confirm whether the waste in the waste channel 170 is blocked, and thus determine whether the waste collection box 150 is full so as to clean it in time.

[0099] In some specific embodiments of this utility model, the waste detection sensor 180 can be a light sensor. When the waste blocks the light, the other side of the waste channel 170 cannot receive the light, or it can continuously receive reflected light, which proves that there is waste in the waste channel 170, causing blockage. This can be used to confirm that the waste collection box 150 is full and needs to be cleaned.

[0100] Accordingly, the waste channel 170 can be made to have an opening to facilitate the entry of light into the waste channel 170 for inspection.
