Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a waste material transfer device and battery production equipment. Background Technology

[0002] After the coating and molding process, the blank areas of the electrode need to be cut, and the excess material cut off from the blank areas needs to be transferred and recycled. In addition, different specifications of products require different cutting dimensions, so the blank areas need to be cut precisely according to the actual product dimensions.

[0003] However, the current electrode cutting process is complex, time-consuming, and labor-intensive, which is not conducive to improving battery production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a waste material transfer device and battery production equipment to address the problems that the current electrode cutting process is complicated, time-consuming, and labor-intensive, which is not conducive to improving battery production efficiency.

[0005] In a first aspect, this application provides a waste material transfer device, including a feeding assembly, a cutting assembly, and a separating assembly. The feeding assembly includes a plurality of conveying rollers rotatably arranged about their own axial direction. The conveying rollers are arranged sequentially along a first direction perpendicular to their own axial direction, and a conveying gap is formed between each pair of adjacent conveying rollers for the electrode sheet to pass through. At least a portion of the outer peripheral surface of each conveying roller is configured as a support surface for supporting the electrode sheet, so as to convey the electrode sheet in a direction parallel to the support surface. The cutting assembly is used to cut the electrode sheet on the support surface along the conveying direction of the electrode sheet to form an electrode sheet body and waste material. The separating assembly is arranged downstream of the cutting assembly along the conveying direction and is used to peel the cut waste material from the support surface. The cutting assembly and the separating assembly are both arranged below the same conveying roller along the gravity direction. The separating assembly includes an actuating component, which includes a plurality of fourth mounting seats and a plurality of pressure rollers correspondingly arranged on each of the fourth mounting seats. The axial direction of each pressure roller is parallel to the axial direction of each conveying roller, and each pressure roller is rotatable about its own axial direction. In the gravity direction, each pressure roller is correspondingly arranged to the electrode sheet body.

[0006] Therefore, through the above structure, not only can the electrode sheets be efficiently cut during the electrode sheet transportation process, but also the surplus material after cutting can be smoothly transferred and recycled, making the operation more convenient and effectively improving the production efficiency of batteries.

[0007] Furthermore, the conveying roller can provide a support surface for the cutting component to facilitate cutting during the coating and forming process of the electrode sheet. At the same time, the separation component is set below the conveying roller along the direction of gravity, so that the remaining material after cutting can be transferred and recycled more easily after being peeled off from the support surface.

[0008] By setting pressure rollers, the electrode body can be more stably attached to and supported on the support surface, thus enabling the smooth transport of the electrode body.

[0009] In some embodiments, the cutting components are movably disposed along a first direction, a second direction and a gravity direction, wherein the first direction, the second direction and the gravity direction are perpendicular to each other.

[0010] Therefore, the above structure allows for more flexible adjustment of the position of the cutting component relative to the electrode sheet, enabling the cutting component to precisely cut the blank area of ​​the electrode sheet, thereby improving the production efficiency and quality of the battery.

[0011] In some embodiments, the cutting assembly includes a first mounting base, a first guide rail, and a cutting blade assembly. The first guide rail extends along a first direction, the first mounting base is movably disposed on the first guide rail along the first direction, and the cutting blade assembly is mounted on the first mounting base.

[0012] Therefore, through the above structure, the cutting component can be moved smoothly in the first direction, thereby flexibly adjusting the cutting position of the cutting component relative to the electrode in the first direction, and better realizing the cutting of the electrode.

[0013] In some embodiments, the first mounting base includes a base body, a fixing member, and a second guide rail. The fixing member is movably disposed on the first guide rail along a first direction, and the second guide rail is disposed on the fixing member and extends along the direction of gravity. The cutter assembly is mounted on the base body, and the base body is movably disposed on the second guide rail along the direction of gravity.

[0014] Thus, the above structure enables the cutting blade assembly to move flexibly in the direction of gravity, so as to adjust the cutting position of the cutting blade assembly relative to the electrode sheet in the direction of gravity, and better achieve the cutting of the electrode sheet.

[0015] In some embodiments, the cutter assembly includes a plurality of cutters and a plurality of second mounting seats, each cutter being disposed on a corresponding second mounting seat, and each second mounting seat being movably disposed on a seat body along a second direction.

[0016] Therefore, the above structure allows for more flexible and precise adjustment of the position of each cutter in the second direction, enabling flexible and precise adjustment of the cutting size according to the actual product dimensions and improving cutting efficiency.

[0017] In some embodiments, each cutter is movably mounted on its corresponding second mounting base along the direction of gravity. This structure allows for fine-tuning of the position of each cutter in the direction of gravity, enabling each cutter to better adapt to different positions on the electrode sheet and making the cutting process smoother.

[0018] In some embodiments, the separation assembly further includes a third mounting base and a third guide rail, an actuating component for peeling off excess material from the support surface, and the actuating component is disposed on the third mounting base; the third guide rail extends along the direction of gravity, and the third mounting base is movably disposed on the third guide rail along the direction of gravity.

[0019] Thus, the above structure enables the movement and positioning of the actuator in the direction of gravity, so as to peel the cut scrap from the support surface through the actuator, thereby realizing the transfer and recycling of the scrap.

[0020] In some embodiments, each fourth mounting base is movably disposed on the third mounting base along the second direction, wherein the first direction, the second direction, and the gravity direction are perpendicular to each other.

[0021] The above structure allows the electrode body to be more stably attached and supported on the support surface, enabling smooth conveying of the electrode body. At the same time, it enables the surplus material to be smoothly separated from the electrode body, achieving the transfer and recycling of the surplus material.

[0022] In some embodiments, the actuating component further includes a plurality of scrapers, each scraper being disposed on a fourth mounting base and corresponding to a pressure roller; wherein, in the direction of gravity, each scraper is disposed corresponding to the residual material to peel the residual material off the support surface.

[0023] The above structure enables the smooth separation of the waste material from the corresponding electrode body, allowing the electrode body to be transported smoothly, and the waste material to be transferred and recycled smoothly.

[0024] In some embodiments, the waste material transfer device further includes a recycling component disposed below the separation component along the direction of gravity to receive the stripped waste material.

[0025] Therefore, by setting up recycling components, the surplus material can be quickly transferred and recycled, which is easy to operate and can effectively improve production efficiency.

[0026] In some embodiments, the waste material transfer device further includes a detection element and a control element. The detection element is used to detect the areal density of the electrode sheet, and the control element is communicatively connected to the detection element, the cutting assembly, and the separation assembly, and is configured to control the position and operating parameters of the cutting assembly and the separation assembly based on the detection result of the detection element.

[0027] Therefore, the above structure allows for more flexible and accurate control of the cutting and separating components, improving production efficiency during the transfer of scrap materials.

[0028] Secondly, this application also provides a battery production apparatus, including the waste material transfer device described above.

[0029] In the aforementioned waste material transfer device and battery production equipment, during the process of conveying the electrode sheets by the feeding component, the cutting component first cuts the electrode sheets, specifically cutting the blank areas of the electrode sheets to separate the electrode sheets into the electrode sheet body and waste material. Then, the waste material can be peeled off from the support surface by the separation component. At the same time, the electrode sheet body is supported on the support surface and smoothly conveyed to the next process by the feeding component. In this way, the electrode sheets can be cut efficiently, and the waste material after cutting can be smoothly transferred and recycled. The operation is more convenient and the battery production efficiency is effectively improved. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0042] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as other fields. With the continuous expansion of the application areas of battery devices, the market demand is also constantly increasing.

[0043] A battery cell is the smallest unit that makes up a battery device. A battery device may include one or more battery cells, which are connected in series, parallel or mixed to form a whole.

[0044] A battery cell typically includes an electrode assembly, a housing, and a top cover. The housing and top cover together enclose a space where the electrode assembly can be placed and filled with electrolyte to wet the electrode assembly.

[0045] Electrode assemblies typically include a positive electrode, a separator, and a negative electrode. The separator serves to isolate and insulate adjacent positive and negative electrodes. The positive and negative electrodes can be collectively referred to as electrodes, and both include coated areas and uncoated areas. The coated areas are those coated with an active material layer, while the uncoated areas are those without an active material layer.

[0046] In the initial coating and molding process, the electrode sheets are relatively large in size to improve efficiency. After coating and molding, the electrode sheets need to be cut according to the actual product size, specifically in the blank area of ​​the electrode sheet. After cutting, the excess material in the blank area becomes scrap material, which can be transferred and recycled.

[0047] However, currently, the cutting and transfer of the blank areas of the electrode sheets are usually done manually with simple scrapers. The operation is relatively complicated, time-consuming and labor-intensive, which is not conducive to improving the production efficiency of batteries.

[0048] Based on the above considerations, and to address the problems of complex, time-consuming, and labor-intensive electrode cutting processes that hinder battery production efficiency, one or more embodiments of this application provide a waste material transfer device. During the electrode feeding process, the cutting component first cuts the electrode, specifically cutting the blank area to separate the electrode into the electrode body and waste material. The waste material can then be peeled off the support surface by a separation component. Simultaneously, the electrode body rests on the support surface and is smoothly conveyed to the next process by the feeding component. This achieves efficient electrode cutting and facilitates the smooth transfer and recycling of waste material after cutting, making operation more convenient and effectively improving battery production efficiency.

[0049] See Figure 1 One embodiment of this application provides a waste material transfer device 100, including a feeding assembly 10, a cutting assembly 20, and a separating assembly 30. The feeding assembly 10 has a support surface for supporting electrode sheets and is used to feed the electrode sheets in a direction parallel to the support surface. The cutting assembly 20 is used to cut the electrode sheets on the support surface along the feeding direction of the electrode sheets to form electrode sheet bodies and waste material. The separating assembly 30 is disposed downstream of the cutting assembly 20 along the feeding direction and is used to peel the cut waste material off the support surface.

[0050] It should be noted that the waste material transfer device 100 provided in this application can be applied to the electrode cutting process, but is not limited to. Specifically, it can cut the blank area of ​​the electrode and transfer and recycle the cut waste material.

[0051] In this process, the electrode is typically formed by coating an active material layer onto a current collector. The area coated with the active material layer forms the main body, while the area without the active material layer forms the blank area. To improve production efficiency, the electrode is usually relatively large in size during the coating process. Therefore, after coating, the blank area of ​​the electrode needs to be cut according to the actual product size. The cut-off material is then transferred and recycled to form the final product.

[0052] The waste material transfer device 100 includes a feeding assembly 10, a cutting assembly 20, and a separating assembly 30. The feeding assembly 10 is a structure capable of conveying the electrode sheet in a specified direction; that is, the feeding assembly 10 can drive the electrode sheet to move in a specified direction. The cutting assembly 20 is a structure capable of cutting the electrode sheet conveyed by the feeding assembly 10, resulting in two parts: the electrode sheet body and waste material. The separating assembly 30 is a structure capable of peeling the cut waste material from the feeding assembly 10, separating the waste material from the electrode sheet body to facilitate the transfer and recycling of the waste material.

[0053] Specifically, the feeding assembly 10 has a support surface on which the electrode sheet can be supported. The electrode sheet is then conveyed by the feeding assembly 10, and the conveying direction of the electrode sheet is parallel to the support surface. When the electrode sheet is supported on the support surface, the cutting assembly 20 can cut the electrode sheet on the support surface along the conveying direction of the electrode sheet, so that the electrode sheet forms two parts: the electrode sheet body and the excess material.

[0054] The separating component 30 is positioned downstream of the cutting component 20 along the conveying direction. This allows the separating component 30 to peel the remaining material from the support surface after the electrode sheet has been cut into two parts: the electrode body and the waste material. This facilitates the transfer and recycling of the waste material. Simultaneously, the electrode body remains supported on the support surface and is conveyed to the next process by the feeding component 10.

[0055] Therefore, through the above structure, not only can the electrode sheets be efficiently cut during the electrode sheet transportation process, but also the surplus material after cutting can be smoothly transferred and recycled, making the operation more convenient and effectively improving the production efficiency of batteries.

[0056] In some embodiments, the feeding assembly 10 includes a plurality of conveying rollers 11, each conveying roller 11 being rotatably arranged about its own axial direction and arranged sequentially along a first direction a perpendicular to its own axial direction, with a conveying gap 12 formed between each pair of adjacent conveying rollers 11 for the electrode sheet to pass through. At least a portion of the outer peripheral surface of each conveying roller 11 is configured as a support surface; the cutting assembly 20 and the separating assembly 30 are both disposed below the same conveying roller 11 along the gravity direction b.

[0057] Specifically, the feeding assembly 10 includes a plurality of conveying rollers 11, each of which is rotatably arranged about its own axis and arranged sequentially along a first direction a perpendicular to its own axis. A conveying gap 12 is formed between each pair of adjacent conveying rollers 11 to allow the electrode sheet to pass through. In this way, the electrode sheet can pass through the conveying gap 12 between adjacent pairs of conveying rollers 11 in sequence and be wound around each conveying roller 11, thus realizing the conveying of the electrode sheet. At the same time, the electrode sheet is in contact with and supported by at least a portion of the support surface of each conveying roller 11, so that the cutting assembly 20 can cut the electrode sheet on the support surface.

[0058] Understandably, before cutting, the current collector of the electrode sheet is stacked with the active material layer to be coated and passes through each conveying gap 12 together. The coating and forming of the electrode sheet can be achieved by the extrusion pressure between two adjacent conveying rollers 11, which is the dry coating process of the electrode sheet.

[0059] Furthermore, both the cutting assembly 20 and the separating assembly 30 are positioned below the same conveying roller 11 along the direction of gravity b. Specifically, the cutting assembly 20 and the separating assembly 30 are typically positioned below the middle conveying roller 11 along the direction of gravity b. This allows the electrode sheet to be better coated and shaped after being squeezed by the first conveying roller 11, and then cut by the cutting assembly 20. After cutting, the remaining material is transferred and recycled using the separating assembly 30.

[0060] In addition, both the cutting component 20 and the separating component 30 are positioned below the conveying roller 11 along the direction of gravity b. After the cutting is completed, the separating component 30 peels the remaining material from the support surface. The remaining material can be better separated from the electrode body and the support surface under the action of gravity, which facilitates the transfer and recycling of the remaining material.

[0061] Thus, through the above structure, the conveying roller 11 can provide a support surface for the cutting component 20 to facilitate cutting during the coating and forming of the electrode sheet. At the same time, the separating component 30 is arranged below the conveying roller 11 along the gravity direction b. After the cut material is peeled off from the support surface, it can be transferred and recycled more conveniently.

[0062] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the cutting components 20 are movably arranged along a first direction a, a second direction c and a gravity direction b, respectively, wherein the first direction a, the second direction c and the gravity direction b are perpendicular to each other.

[0063] Specifically, the first direction a refers to the arrangement direction of each conveying roller 11, that is, the first horizontal direction. The second direction c is perpendicular to the first direction a and the gravity direction b, that is, the second direction c is the second horizontal direction and is parallel to the axial direction of each conveying roller 11.

[0064] It should be noted that different product specifications require different electrode sizes. Therefore, the cutting position of the electrode needs to be adjusted flexibly according to different products.

[0065] Based on this, the cutting component 20 is movably set along the first direction a, the second direction c, and the gravity direction b, respectively. In this way, the cutting component 20 can move more flexibly according to the actual product size, making the cutting size more accurate.

[0066] Therefore, the above structure allows for more flexible adjustment of the position of the cutting component 20 relative to the electrode sheet, enabling the cutting component 20 to precisely cut the blank area of ​​the electrode sheet, thereby improving the production efficiency and quality of the battery.

[0067] like Figure 2 and Figure 3As shown, in some embodiments, the cutting assembly 20 includes a first mounting base 21, a first guide rail 22, and a cutting blade assembly 23. The first guide rail 22 extends along a first direction a, the first mounting base 21 is movably disposed on the first guide rail 22 along the first direction a, and the cutting blade assembly 23 is mounted on the first mounting base 21.

[0068] Specifically, the cutter assembly 23 refers to the component that actually performs the cutting operation on the electrode sheet. The cutter assembly 23 is disposed on the first mounting base 21, and then the cutter assembly 23 is mounted on the first guide rail 22 through the first mounting base 21.

[0069] Furthermore, the first guide rail 22 extends along the first direction a, and the first mounting base 21 can drive the cutter assembly 23 on it to move along the first direction a on the first guide rail 22, thereby realizing the movement of the cutter assembly 23 in the first direction a.

[0070] Therefore, with the above structure, the cutting component 20 can be moved smoothly in the first direction a, thereby flexibly adjusting the cutting position of the cutting component 20 relative to the electrode in the first direction a, and better realizing the cutting of the electrode.

[0071] like Figure 2 and Figure 4 As shown, in some embodiments, the first mounting base 21 includes a base body 211, a fixing member 212, and a second guide rail 213. The fixing member 212 is movably disposed on the first guide rail 22 along a first direction a, and the second guide rail 213 is disposed on the fixing member 212 and extends along the gravity direction b. The cutter assembly 23 is mounted on the base body 211, and the base body 211 is movably disposed on the second guide rail 213 along the gravity direction b.

[0072] Specifically, the fixing member 212 may be, but is not limited to, a fixing plate, which is connected to the first guide rail 22 so that the fixing plate can move along the first direction a on the first guide rail 22.

[0073] Meanwhile, the second guide rail 213 is mounted on the fixing member 212 and extends along the direction of gravity b. Further, the cutter assembly 23 is mounted on the base 211, and the base 211 is connected to the second guide rail 213, so that the base 211 can drive the cutter assembly 23 on it to move along the direction of gravity b on the second guide rail 213.

[0074] Thus, through the above structure, the cutting blade assembly 23 can move flexibly in the direction of gravity b, so as to adjust the cutting position of the cutting blade assembly 23 relative to the electrode sheet in the direction of gravity b, and better achieve the cutting of the electrode sheet.

[0075] In some embodiments, the cutter assembly 23 includes a plurality of cutters 231 and a plurality of second mounting seats 232, each cutter 231 being disposed on a corresponding second mounting seat 232, and each second mounting seat 232 being movably disposed on a seat body 211 along a second direction c.

[0076] Specifically, each second mounting base 232 is equipped with a cutter 231, and each second mounting base 232 is movably mounted on the base body 211 along the second direction c. In this way, each second mounting base 232 can drive the corresponding cutter 231 to move along the second direction c on the base body 211. Each cutter 231 corresponds to a cutting position on the electrode sheet, thereby allowing for more flexible and precise adjustment of the electrode sheet cutting size according to the actual product size, improving cutting efficiency.

[0077] Therefore, through the above structure, the position of each cutter 231 in the second direction c can be adjusted more flexibly and precisely, so as to adjust the cutting size flexibly and precisely according to the actual product size and improve cutting efficiency.

[0078] In some embodiments, each cutter 231 is movably disposed on a corresponding second mounting base 232 along the direction of gravity b.

[0079] Specifically, each cutter 231 can be mounted on the corresponding second mounting base 232 by means of a slide cylinder assembly, so as to realize the fine adjustment of the position of each cutter 231 in the gravity direction b, so that each cutter 231 can realize the feeding action in the gravity direction b.

[0080] The above structure allows for fine-tuning of the position of each cutter 231 in the direction of gravity b, enabling each cutter 231 to better adapt to different positions of the electrode sheet and making the cutting process smoother.

[0081] In addition, each of the second mounting bases 232 can be connected to the base body 211 by screwing, which enables each cutter 231 to be finely adjusted in the second direction c.

[0082] Please refer to the following: Figure 1 and Figure 5 In some embodiments, the separation assembly 30 includes an actuating component 31, a third mounting base 32, and a third guide rail 33. The actuating component 31 is used to peel off excess material from the support surface and is disposed on the third mounting base 32. The third guide rail 33 extends along the gravity direction b, and the third mounting base 32 is movably disposed on the third guide rail 33 along the gravity direction b.

[0083] Specifically, the separation assembly 30 includes an execution component 31, a third mounting base 32, and a third guide rail 33. The execution component 31 is the component that actually performs the separation operation on the cut electrode body and the remaining material. The execution component 31 can separate the electrode body and the remaining material along the cutting path of the cutter 231, so that the remaining material can be detached from the electrode body for easy transfer and recycling.

[0084] The third guide rail 33 extends along the direction of gravity b, and the actuator 31 is mounted on the third mounting base 32. Then, the third mounting base 32 is connected to the third guide rail 33, so that the third mounting base 32 can drive the actuator 31 on it to move along the direction of gravity b on the third guide rail 33.

[0085] Thus, through the above structure, the actuator 31 can be moved and positioned in the direction of gravity b, so that the cut scrap can be peeled off from the support surface by the actuator 31, thereby realizing the transfer and recycling of the scrap.

[0086] In some embodiments, the actuating component 31 includes a plurality of fourth mounting seats 311 and a plurality of pressure rollers 312, each pressure roller 312 being correspondingly disposed on each of the fourth mounting seats 311, and each of the fourth mounting seats 311 being movably disposed on a third mounting seat 32 along the second direction c. The axial direction of each pressure roller 312 is parallel to the axial direction of each conveying roller 11, and each pressure roller 312 is rotatable about its own axial direction. In the gravity direction b, each pressure roller 312 is correspondingly disposed to the electrode body; the first direction a, the second direction c, and the gravity direction b are perpendicular to each other.

[0087] Specifically, the pressure roller 312 presses against the surface of the electrode body, allowing the electrode body to adhere more stably to the support surface, and then follow the conveyor roller 11 to the next process. At the same time, the excess material can separate from the electrode body under the action of gravity and peel off from the support surface, thereby realizing the transfer and recycling of the excess material.

[0088] Each fourth mounting base 311 is provided with a pressure roller 312, and the fourth mounting base 311 is movably disposed on the third mounting base 32 along the second direction c. In this way, each fourth mounting base 311 can drive the pressure roller 312 on it to move in the second direction c, so as to adjust the specific position of each pressure roller 312 in the second direction c, so that each pressure roller 312 better corresponds to the electrode body.

[0089] The above structure allows the electrode body to be more stably attached and supported on the support surface, enabling smooth conveying of the electrode body. At the same time, it enables the surplus material to be smoothly separated from the electrode body, achieving the transfer and recycling of the surplus material.

[0090] In some embodiments, the actuating component 31 further includes a plurality of scrapers 313, each scraper 313 being disposed on each fourth mounting base 311 and corresponding one-to-one with each pressure roller 312. In the direction of gravity b, each scraper 313 is disposed corresponding to the remaining material to peel the remaining material from the supporting surface.

[0091] Specifically, each fourth mounting base 311 can also be equipped with a scraper 313. When the pressure roller 312 is set in correspondence with the electrode body, the scraper 313 that cooperates with the pressure roller 312 can correspond to the position of the residual material. Then, the scraper 313 peels the residual material off the support surface, so that the residual material is successfully separated from the electrode body.

[0092] The above structure enables the smooth separation of the waste material from the corresponding electrode body, allowing the electrode body to be transported smoothly, and the waste material to be transferred and recycled smoothly.

[0093] In addition, a scraper 314 can be set at the position corresponding to each pressure roller 312. The scraper 314 can cooperate with the corresponding pressure roller 312 to make the electrode body more stably attached to the support surface, so as to realize the smooth transportation of the electrode body.

[0094] like Figure 1 As shown, in some embodiments, the waste material transfer device 100 further includes a recycling component 40, which is disposed below the separation component 30 along the gravity direction b to receive the stripped waste material.

[0095] Specifically, the recycling component 40 may, but is not limited to, use a collection box, and place the collection box directly below the separation component 30 along the direction of gravity b. In this way, when the separation component 30 peels the cut scraps from the support surface, the scraps fall into the collection box under the action of gravity, thus realizing the recycling of the scraps.

[0096] Therefore, by setting up the recycling component 40, the surplus material can be quickly transferred and recycled, which is easy to operate and can effectively improve production efficiency.

[0097] In some embodiments, the waste material transfer device 100 further includes a detection element (not shown) and a control element (not shown). The detection element is used to detect the areal density of the electrode sheet. The control element is communicatively connected to the detection element, the cutting assembly 20 and the separation assembly 30, and is configured to control the position and operating parameters of the cutting assembly 20 and the separation assembly 30 according to the detection result of the detection element.

[0098] Specifically, the testing component may be, but is not limited to, a surface density measuring instrument, which can measure the surface density at different locations on the electrode to better determine the cutting position.

[0099] Furthermore, both the cutting component 20 and the separating component 30 can move in the first direction a, the second direction c, or the gravitational direction b by setting corresponding drive components. Thus, the control unit is communicatively connected to the drive components of the cutting component 20 and the separating component 30, respectively. When the control unit receives the detection result from the detection component, it can control the drive components of the cutting component 20 and the separating component 30, thereby controlling the movement of the cutting component 20 and the separating component 30 in the first direction a, the second direction c, or the gravitational direction b.

[0100] In addition, the operating parameters of the cutting component 20 and the separating component 30 may include the setting angle of the cutter 231, the setting angle of the scraper 313, and the rotation speed of the cutter 231.

[0101] Therefore, the above structure enables more flexible and accurate control of the cutting component 20 and the separating component 30, thereby improving production efficiency during the transfer of scrap materials.

[0102] Based on the same concept as the above-described waste material transfer device 100, this application also provides a battery production apparatus, including the waste material transfer device 100 as described above.

[0103] According to one or more embodiments, when this application is used, the current collector, active material layer or other coating material are first stacked and passed through the conveying gap 12 between the conveying rollers 11, and the electrode sheet is extruded and shaped by the conveying rollers 11.

[0104] After being formed, the electrode sheet continues to move with the conveyor roller 11. The specific positions of the cutter 231 in the first direction a, the second direction c, and the gravity direction b are adjusted according to the actual product size. The cutter 231 cuts the blank area of ​​the electrode sheet to form the electrode sheet body and the remaining material.

[0105] After being cut, the electrode body and the remaining material pass through the separation component 30. At this time, the pressure roller 312 and the corresponding scraper 314 make the electrode body more stably adhere to the support surface and continue to be conveyed to the next process by the conveying roller 11. At the same time, the scraper 313 peels the remaining material off the support surface, causing the remaining material to fall into the recycling component 40, so as to realize the transfer and recycling of the remaining material.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
