Description

Technical Field

[0001] The present application relates to the field of battery production technology, and in particular to a coil processing device, a coil processing method and a coating system. Background Art

[0002] In the coating production process, in order to prevent the coil from spreading during the loading and unloading process, a fixed label is usually attached to the break of the coil to fix the break. Before changing the roll, the coil needs to be pre-processed and the fixed label attached to the coil is torn off so that the break of the coil can be connected with the break of other coils during the subsequent roll change. However, the efficiency and accuracy of the current coil pretreatment operation are low, which may have a serious impact on the preparation yield, quality and production efficiency of the electrode in the subsequent coating process. Summary of the invention

[0003] In view of the above problems, the present application provides a coil material processing device, a coil material processing method and a coating system, which can improve the coil material processing efficiency.

[0004] In the first aspect, an embodiment of the present application provides a roll material processing device, including a carrying mechanism, a detection mechanism and a peeling mechanism, the carrying mechanism including a first driving member and a carrying shaft connected to the first driving member, the carrying shaft is used to carry the roll material, and the first driving member is used to drive the carrying shaft to rotate; the detection mechanism is arranged at an interval from the carrying shaft, and is used to detect the position of the adhesive tape attached to the roll material; the peeling mechanism is located on one side of the carrying shaft along a first direction, and the peeling mechanism is used to peel the adhesive tape from the roll material, and the first direction is perpendicular to the axial direction of the carrying shaft.

[0005] In the above scheme, the bearing shaft passes through the coil along the axial direction of the coil to support and fix the coil. The detection mechanism can detect the position of the adhesive tape attached to the coil. On this basis, the bearing shaft is driven to rotate by the first driving member, and the bearing shaft drives the coil to rotate, and the position of the adhesive tape attached to the coil can be adjusted so that the adhesive tape corresponds to the position of the peeling mechanism, so that the adhesive tape is peeled off from the coil by the peeling mechanism. On the one hand, the adhesive tape can be automatically removed and the pretreatment efficiency of the coil can be improved. On the other hand, the above-mentioned automatic mechanisms are used to peel the adhesive tape on the coil, which can effectively improve the peeling accuracy of the adhesive tape and improve the pretreatment quality of the coil, thereby improving the preparation yield and quality of the pole piece in the subsequent coating process, and improving the production efficiency and performance of the battery cell and battery device.

[0006] In some embodiments, the peeling mechanism includes a second driving member and a peeling member, the second driving member is connected to the peeling member and is used to drive the peeling member to move axially along the bearing shaft, and the peeling member is used to drive the adhesive tape to separate from the roll material.

[0007] In the above scheme, the second driving member drives the stripping member to move along the axial direction of the bearing shaft, so that the stripping member and the adhesive tape on the roll material on the axial direction of the bearing shaft correspond to each other, so that the stripping member can easily strip the adhesive tape. In addition, the second driving member drives the stripping member to move along the axial direction of the bearing shaft, so that the stripping member can also be capable of stripping the adhesive tape at different positions of the roll material, thereby improving the flexibility and practicality of the stripping mechanism and the efficiency of stripping the adhesive tape.

[0008] In some embodiments, the detection mechanism includes a first detection member, which is used to detect the position of the adhesive tape in the axial direction and the second direction of the load-bearing shaft, wherein the first direction, the second direction and the axial direction of the load-bearing shaft are perpendicular to each other.

[0009] In the above scheme, the detection mechanism includes a first detection member, through which the position of the adhesive tape in the axial direction and the second direction of the load-bearing shaft can be accurately detected. On this basis, the relative positions of the adhesive tape and the peeling member are adjusted by the first driving member and the second driving member, which can effectively improve the efficiency and accuracy of the position adjustment of the adhesive tape and the peeling member, and improve the success rate of peeling off the adhesive tape by the peeling member and the pre-processing quality of the roll material.

[0010] In some embodiments, the detection mechanism further includes a second detection member, which is disposed on the peeling member and is used to identify the adhesive tape during the axial movement of the peeling member along the bearing shaft.

[0011] In the above scheme, on the basis of detecting the position of the adhesive tape along the axial direction and the second direction of the load-bearing shaft by the first detection member, the adhesive tape is identified by the second detection member during the axial movement of the stripping member along the load-bearing shaft, thereby improving the position accuracy of the stripping member and the adhesive tape in the axial direction of the load-bearing shaft, and further improving the success rate of stripping the adhesive tape by the stripping member.

[0012] In some embodiments, there are multiple stripping members, which are arranged axially along the load-bearing shaft. The second driving member is detachably connected to each stripping member, and is used to drive at least one stripping member to move axially along the load-bearing shaft.

[0013] In the above scheme, the second driving member is detachably connected to each peeling member. During the process of peeling off the adhesive tape on the roll material, the second driving member is connected to part of the peeling members and separated from the remaining peeling members to drive the part of the peeling members without driving all the peeling members at the same time. This can reduce the power consumption of the second driving member and increase the service life of the second driving member.

[0014] In some embodiments, the second driving member includes a linear module and a connecting component, the connecting component includes a main body and a rod portion, the main body is connected to the linear module, and the rod portion is retractable relative to the main body in a direction close to or away from the stripping member for engaging with or separating from the stripping member.

[0015] In the above scheme, the linear module is detachably connected to the stripping member through a connecting component to drive the stripping member to move axially along the bearing shaft. The connecting component includes a main body and a rod. The main body is connected to the linear module. The rod is retractable relative to the main body in a direction close to or away from the stripping member. It can be engaged with the stripping member or separated from the stripping member, thereby realizing a detachable connection with the stripping member. The structure is simple and the operation is convenient.

[0016] In some embodiments, the stripping mechanism further includes a third driving member, the second driving member is connected to the stripping member via the third driving member, and the third driving member is used to drive the stripping member to move along the first direction.

[0017] In the above scheme, when the stripping member corresponds to the adhesive tape on the roll along the axial direction of the load-bearing shaft and the second direction, the stripping member is driven by the third driving member to move along the first direction toward the side close to the load-bearing shaft, which can shorten the distance between the stripping member and the corresponding adhesive tape along the first direction and reduce the difficulty of connecting the stripping member and the corresponding adhesive tape, so as to facilitate the connection between the stripping member and the adhesive tape, thereby driving the adhesive tape to be peeled off from the roll.

[0018] In some embodiments, the roll material processing device also includes a gluing mechanism, which is arranged on one side of the load-bearing shaft along the first direction, and the gluing mechanism includes a unwinding assembly, a winding assembly and a gluing assembly. The unwinding assembly is used to set a tape roll, and the tape roll includes a substrate and a colloid arranged on the surface of the substrate; the winding assembly is used to wind up the substrate; the gluing assembly includes a fourth driving member and a gluing member connected to the fourth driving member, the fourth driving member is used to drive the gluing member to move along the first direction, and the gluing member is used to push the substrate along the first direction so that the colloid on the substrate is attached to the surface of the roll material.

[0019] In the above scheme, after the adhesive tape on the coil is peeled off by the peeling mechanism, the colloid is attached to the surface of the coil by the gluing mechanism, so that the automatic gluing of the coil can be realized without manually gluing the coil, which can further improve the processing efficiency and processing accuracy of the coil, and help improve the preparation yield and quality of the electrode in the subsequent coating process. The coil after gluing can be bonded with the coil to be replaced in the coating device when it is transported to the coating device, so as to realize the reel change of the coating device. Among them, the unwinding component is used to set the tape roll, which can unwind to the gluing part of the gluing component, and the gluing part can push the substrate of the tape roll to move along the first direction toward the side close to the bearing shaft under the drive of the fourth driving member, so that the colloid on the surface of the substrate contacts and bonds with the surface of the coil, and realizes the automatic gluing of the coil. When the colloid is bonded to the surface of the coil, the substrate is separated from the corresponding colloid, and then the separated substrate is automatically rewound by the rewinding component without the need to manually recycle the substrate, which can improve the automation of the coil processing device and further improve the coil processing efficiency.

[0020] In some embodiments, the gluing mechanism is movably arranged along the axial direction of the load-bearing shaft, the gluing part includes an incoming side and an outgoing side relatively arranged along the axial direction of the load-bearing shaft, the unwinding component unwinds from the incoming side through the gluing part toward a side surface of the load-bearing shaft, and toward the outgoing side, the gluing mechanism also includes a re-pressing component, the re-pressing component is arranged on the outgoing side of the gluing part, the re-pressing component includes a fifth driving member and a re-pressing member connected to the fifth driving member, the fifth driving member is used to drive the re-pressing member to move along the first direction, and the re-pressing member is used to press the roll material and the glue attached to the surface of the roll material along the first direction.

[0021] In the above scheme, the unwinding component unwinds from the incoming material side through the adhesive sticking part toward the side surface of the bearing shaft, and toward the discharge side, that is, the substrate of the tape roll extends from the incoming material side through the adhesive sticking part toward the side surface of the bearing shaft, and toward the discharge side. The colloid on the substrate surface is located on the side of the substrate away from the adhesive sticking part. When the fourth driving member drives the adhesive sticking part to move along the first direction toward the side close to the bearing shaft, the colloid on the substrate surface can contact and bond with the surface of the roll on the bearing shaft, so as to realize the automatic gluing of the roll. On this basis, a re-pressing component is arranged on the discharge side of the adhesive sticking part. The re-pressing component includes a fifth driving member and a re-pressing member. The re-pressing member can move along the first direction toward the bearing shaft under the drive of the fifth driving member. When the adhesive sticking part pushes the substrate so that the colloid on its surface is attached to the surface of the roll, during the axial movement of the adhesive sticking mechanism along the bearing shaft, the re-pressing member can press the roll and the colloid attached to its surface along the first direction, so that the contact between the colloid and the roll is closer.

[0022] In some embodiments, the roll material processing device also includes a base, which includes a base body and a driving component arranged on the base body. The supporting mechanism, detection mechanism and peeling mechanism are integrated on the base body, and the driving component is used to drive the base body to move toward the coating device.

[0023] In the above scheme, the carrying mechanism, the detection mechanism and the peeling mechanism are integrated into the machine base body. After the pre-processing of the coil on the carrying mechanism is completed, the machine base body is driven by the driving component to move toward the coating device, and the processed coil is transported to the coating device to facilitate the processes such as coil changing and slurry coating of the coating device.

[0024] In some embodiments, the driving assembly includes at least one driving wheel and at least one driven wheel. The driving wheel and the driven wheel are spaced apart and located on a side of the base body away from the peeling mechanism. The driving wheel is used to drive the base body to move.

[0025] In the above scheme, the driving wheel and the driven wheel are both arranged on the side of the machine base body away from the peeling mechanism, that is, on the side of the machine base body facing the ground. The driving wheel drives the machine base body to move, which can improve the stability of the machine base body during the movement process and reduce the overall volume of the driving assembly. In addition, during the movement of the machine base body, the driven wheel rotates under the drive of the machine base body, which can assist the driving wheel to further improve the stability of the machine base body.

[0026] In some embodiments, the base body includes a supporting plate, a first bracket and a sixth driving member. The first bracket is connected to the supporting plate through the sixth driving member. The sixth driving member is used to drive the first bracket to move along a first direction relative to the supporting plate. The peeling mechanism is arranged on the first bracket.

[0027] In the above scheme, the first bracket is connected to the bearing plate through the sixth driving member, and the stripping mechanism is arranged on the first bracket. When it is necessary to strip the adhesive tape on the roll material on the bearing shaft through the stripping mechanism, the first bracket is driven by the sixth driving member to move along the first direction toward the side close to the bearing shaft, which can shorten the distance between the stripping mechanism and the roll material, so as to reduce the difficulty of the stripping mechanism to strip the adhesive tape on the surface of the roll material. When it is not necessary to work through the stripping mechanism, the first bracket is driven by the sixth driving member to move along the first direction toward the side away from the bearing shaft, which can increase the distance from the bearing shaft to the stripping mechanism and the first bracket, so that there is sufficient space around the bearing shaft for realizing other operations such as assembly or disassembly of the roll material.

[0028] In some embodiments, the roll material processing device also includes a sample storage bin and a tape cutting mechanism, the tape cutting mechanism is arranged on one side of the stripping mechanism along the second direction, the sample storage bin is arranged on the side of the tape cutting mechanism away from the stripping mechanism along the second direction, and the opening of the sample storage bin faces the tape cutting mechanism.

[0029] In the above scheme, the tape cutting mechanism is arranged on one side of the stripping mechanism along the second direction. After the stripping mechanism strips off the adhesive tape on the roll material, the first driving member drives the supporting shaft to rotate, so that the roll material can be spread out and part of the tape of the roll material is released. The released tape stretches along the second direction toward the direction close to the tape cutting mechanism, so that the tape is cut by the tape cutting mechanism, so that part of the tape is separated from the roll material. Since the sample storage bin is arranged on the side of the tape cutting mechanism away from the stripping mechanism along the second direction, and the opening of the sample storage bin faces the tape cutting mechanism, the tape cut by the tape cutting mechanism can enter the sample storage bin through the opening for storage, thereby realizing automatic sampling of the roll material, which can further improve the degree of automation of the roll material processing device and further improve the roll material processing efficiency.

[0030] In some embodiments, the sample storage chamber includes a chamber body and a seventh driving member connected to the chamber body, and the seventh driving member is used to drive the chamber body to move along the first direction.

[0031] In the above scheme, when it is necessary to sample the coiled material, the seventh driving member drives the bin body to move along the first direction toward the side close to the bearing shaft, so that the bin body extends out, and the opening of the bin body corresponds to the position of the tape cutting mechanism along the first direction, so that the tape cut by the tape cutting mechanism can enter the sample storage bin through the opening. When it is not necessary to sample the coiled material, the seventh driving member drives the bin body to move along the first direction toward the side away from the bearing shaft, so that the bin body is retracted, which can reduce the risk of mutual interference between the bin body and other structures of the coiled material processing mechanism.

[0032] In some embodiments, the roll material processing device also includes a material bin, which is arranged on the side of the tape cutting mechanism away from the peeling mechanism along the second direction, and the opening of the material bin faces the tape cutting mechanism. The material bin includes a first sub-bin, a second sub-bin and a ninth driving member. The first sub-bin and the second sub-bin are connected to each other and arranged along the first direction. The ninth driving member is connected to at least one of the first sub-bin and the second sub-bin, and is used to drive the first sub-bin and the second sub-bin to move along the first direction.

[0033] In the above scheme, the silo can be used to store the waste material on the outermost layer of the coil. By setting the silo on the side of the tape cutting mechanism away from the stripping mechanism, and the opening of the silo faces the tape cutting mechanism, after the waste material on the outermost layer of the coil is cut by the tape cutting mechanism, the waste material can enter the silo through the opening of the silo, thereby realizing automatic cutting and recycling of the waste material, which can further improve the automation degree of the coil processing device, further improve the coil processing efficiency, and reduce the interference of the waste material on other structures in the coil processing device. In addition, in the silo, the first sub-bin and the second sub-bin can be used to classify and recycle different types of waste materials. The tape cutting mechanism can cut the different types of waste materials on the outermost layer of the coil respectively. During the cutting process, the first sub-bin and the second sub-bin are driven by the ninth driving member to move along the first direction, so that the opening of the first sub-bin or the opening of the second sub-bin corresponds to the position of the tape cutting mechanism along the second direction, so that the cut different types of waste materials enter the first sub-bin and the second sub-bin through the corresponding openings, respectively, to realize the classification and recycling of different types of waste materials, and reduce the mutual influence between different types of waste materials.

[0034] In some embodiments, the coil material processing device also includes a spray mechanism, which is arranged on one side of the load-bearing shaft along the second direction, and is used to spray liquid onto the inner surface of the material strip after the coil material is released. The spray mechanism includes a nozzle and a tenth driving member connected to the nozzle, and the tenth driving member is used to drive the nozzle to rotate around a rotation axis, and the rotation axis extends along the axial direction of the load-bearing shaft.

[0035] In the above scheme, after the stripping mechanism strips the adhesive tape on the roll, the first driving member drives the bearing shaft to rotate, so that the roll can be spread out, part of the material strip of the roll is released, and the released material strip can be extended along the second direction. Therefore, the liquid is sprayed on the inner surface of the released material strip through the nozzle of the spray mechanism, and then the first driving member drives the bearing shaft to rotate in the opposite direction, so that the released material strip is rewound to the outer periphery of the unreleased material strip, and the inner surface of the released material strip can be bonded to the outer surface of the unreleased material strip through the liquid, thereby reducing the risk of the roll being spread out in the process of being transported to the coating device later. On this basis, the tenth driving member drives the nozzle to rotate around the rotation axis, and the rotation axis extends along the axial direction of the bearing shaft, so that the angle of the nozzle when spraying liquid on the inner surface of the released material strip can be adjusted to improve the liquid spraying effect.

[0036] In a second aspect, an embodiment of the present application further provides a coil material processing method, comprising: placing a coil on a load bearing shaft; The position of the adhesive tape attached to the roll material in the initial state is detected by a detection mechanism; The time required for the bearing shaft to drive the adhesive tape to rotate to a preset position is calculated according to the position of the adhesive tape in the initial state detected by the detection mechanism, the rotation speed of the bearing shaft and the outer diameter of the coil; The adhesive tape is driven to a preset position by rotating the bearing shaft at a corresponding speed for a corresponding time; The adhesive tape at the preset position is peeled off from the roll material by the peeling mechanism.

[0037] In the above scheme, the coil is first loaded and set on the bearing shaft, and then the position of the adhesive tape on the coil in the initial state is detected by the detection mechanism, and based on the position in the initial state, the rotation speed of the bearing shaft, the outer diameter of the coil and other parameters, the time required for the bearing shaft to drive the adhesive tape to rotate to a preset position at a corresponding rotation speed is calculated. After the bearing shaft rotates for a corresponding time, the bearing shaft is controlled to stop rotating, and then the adhesive tape at the preset position is peeled off from the coil by the peeling mechanism. On the one hand, the automatic removal of the adhesive tape can be realized, and on the other hand, the above method is used to peel off the adhesive tape on the coil, which can effectively improve the peeling accuracy of the adhesive tape and improve the pretreatment quality of the coil, thereby improving the preparation yield and quality of the electrode in the subsequent coating process, and improving the production efficiency and performance of battery cells and battery devices.

[0038] In some embodiments, the step of detecting the initial position of the adhesive tape attached to the roll material by the detection mechanism includes: Detecting the position of the adhesive tape along the axial direction and the second direction of the load-bearing shaft in the initial state by the first detection member; The step of peeling the adhesive tape at a preset position from the roll material by the peeling mechanism comprises: The stripping member is driven to move along the axial direction of the bearing shaft by the second driving member, and the adhesive tape is identified by the second detecting member during the movement of the stripping member; After the second detection member identifies the adhesive tape, the stripping member stops moving and strips the adhesive tape.

[0039] In the above scheme, after the first detection member detects the position of the adhesive tape along the axial direction and the second direction of the bearing shaft in the initial state, the time required for the bearing shaft to drive the adhesive tape to rotate to the preset position at a corresponding speed is calculated based on parameters such as the position, and after the bearing shaft rotates for a corresponding time, the bearing shaft is controlled to stop rotating. Subsequently, the stripping member is driven by the second driving member to move along the axial direction of the bearing shaft, so that the stripping member has the ability to strip the adhesive tape at different positions of the roll material, thereby improving the flexibility and practicality of the stripping mechanism and the stripping efficiency of the adhesive tape. In addition, during the movement process, the adhesive tape on the roll material is identified by the second detection member arranged on the stripping member. After the second detection member identifies the adhesive tape, the stripping member stops moving. At this time, the position of the stripping member corresponds to that of the adhesive tape, and the stripping member can accurately strip the adhesive tape, which can improve the position accuracy of the stripping member and the adhesive tape in the axial direction of the bearing shaft, and further improve the success rate of stripping the adhesive tape by the stripping member and the pre-treatment quality of the roll material.

[0040] In a third aspect, an embodiment of the present application further provides a coating system, comprising any of the above coil material processing devices and a coating die, wherein the coating die is used to coat slurry on a material strip released from the coil material.

[0063] As an example, the box body may include a top cover, a frame and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that a closed space is formed inside the box body to accommodate the battery cell assembly.

[0064] In some embodiments, the box body can be used as a part of the chassis structure of the vehicle. For example, part of the box body can become at least a part of the floor of the vehicle, or part of the box body can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0065] The technical solutions described in the embodiments of the present application are applicable to various electrical devices that use battery cells, such as mobile phones, portable devices, laptop computers, electric vehicles, electric toys, electric tools, vehicles, ships and spacecraft, for example, spacecraft include airplanes, rockets, space shuttles and spacecraft, etc.

[0066] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0067] The battery cell can be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., which is not limited in the embodiments of the present application.

[0068] A battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode sheet, a negative electrode sheet, and a separator, which is arranged between the negative electrode sheet and the positive electrode sheet. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and removed back and forth between the positive electrode sheet and the negative electrode sheet. The separator is arranged between the positive electrode sheet and the negative electrode sheet to prevent the positive and negative electrodes from short-circuiting, while allowing active ions to pass through.

[0069] In some embodiments, the positive electrode sheet may include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector. The negative electrode sheet may include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector. In the production process of the electrode sheet, the corresponding electrode sheet may be formed by coating the surface of the coil with the corresponding active material and then cutting the coil coated with the active material.

[0070] A coil refers to a component formed by winding a substrate around an axis. A fixed label is usually provided at the fracture of the coil to fix the fracture and prevent the coil from loosening. In the coating production process of the coil, before the coil is transported to the coating device for coil change and slurry coating, it is necessary to perform pretreatment operations such as tearing off the fixed label attached to the coil, cutting off the waste material on the outermost layer of the coil, retaining a sample of the coil, and attaching a colloid to the surface of the coil. This not only helps to improve the quality of the pole pieces prepared in the subsequent coating process and improve the performance of the battery cells and battery devices, but also the pretreated coil can be quickly and accurately changed in the subsequent coating process, thereby improving the preparation efficiency and yield of the pole pieces.

[0071] However, the current pretreatment operation of the coil is not only highly dependent on manual labor, but also has low operating accuracy. For example, when tearing off the fixed label attached to the coil, other parts of the coil may be accidentally torn, or when attaching the colloid to the surface of the coil, the attachment position of the colloid has a large deviation, which affects the subsequent coil changing accuracy and coating accuracy. These factors will affect the pretreatment quality of the coil, and then have a serious impact on the preparation yield and quality of the electrode in the subsequent coating process, and even affect the production efficiency and performance of battery cells and battery devices.

[0072] Therefore, in order to solve at least part of the above problems, the embodiments of the present application provide a roll material processing device, a roll material processing method and a coating system, wherein the roll material processing device includes a bearing mechanism, a detection mechanism and a peeling mechanism, wherein the bearing mechanism includes a first driving member and a bearing shaft connected to the first driving member, wherein the bearing shaft is used to bear the roll material, and the first driving member is used to drive the bearing shaft to rotate; the detection mechanism is spaced apart from the bearing shaft, and is used to detect the position of the adhesive tape attached to the roll material; the peeling mechanism is located on one side of the bearing shaft along a first direction, and the peeling mechanism is used to peel the adhesive tape from the roll material, and the first direction is perpendicular to the axial direction of the bearing shaft. The bearing shaft passes through the roll material along the axial direction of the roll material to support and fix the roll material. The detection mechanism can detect the position of the adhesive tape attached to the roll material, and on this basis, the first driving member drives the bearing shaft to rotate, and the bearing shaft drives the roll material to rotate, so that the position of the adhesive tape attached to the roll material can be adjusted so that the adhesive tape corresponds to the position of the peeling mechanism, thereby peeling the adhesive tape from the roll material through the peeling mechanism. On the one hand, the adhesive tape can be automatically removed and the pretreatment efficiency of the roll material can be improved. On the other hand, the above-mentioned automated mechanisms are used to peel off the adhesive tape on the roll material, which can effectively improve the peeling accuracy of the adhesive tape and improve the pretreatment quality of the roll material, thereby improving the preparation yield and quality of the electrode in the subsequent coating process, and improving the production efficiency and performance of battery cells and battery devices.

[0073] Next, the structure of the coil material processing device will be described in detail in conjunction with the accompanying drawings in the embodiments of the present application.

[0074] First, see Figure 1 The embodiment of the present application provides a roll material processing device, including a carrying mechanism 100, a detection mechanism 200 and a peeling mechanism 300. The carrying mechanism 100 includes a first driving member and a carrying shaft 110 connected to the first driving member. The carrying shaft 110 is used to carry the roll material 10, and the first driving member is used to drive the carrying shaft 110 to rotate; the detection mechanism 200 is arranged at an interval with the carrying shaft 110, and is used to detect the position of the adhesive tape attached to the roll material 10; the peeling mechanism 300 is located on one side of the carrying shaft 110 along the first direction X, and the peeling mechanism 300 is used to peel the adhesive tape from the roll material 10. The first direction X is perpendicular to the axial direction of the carrying shaft 110.

[0075] It should be noted that the coil material processing device in the embodiment of the present application can be applied to the battery field, and the coil material 10 processed by it can be a substrate 21 for making a battery electrode, or the coil material processing device can also be applied to other fields such as the display field. The adhesive tape mentioned in the embodiment of the present application can be a fixed label attached to the surface of the coil material 10, or it can also be other structures on the coil material 10.

[0076] The bearing mechanism 100 is a component for supporting and fixing the coil 10 during the processing of the coil 10. The bearing mechanism 100 includes a first driving member and a bearing shaft 110. The bearing shaft 110 may be cylindrical and may pass through the coil 10 along the axial direction of the coil 10 to provide physical support for the coil 10. In addition, the bearing shaft 110 may also be used to drive the coil 10 thereon to rotate. When the bearing shaft 110 rotates under the drive of the first driving member, the coil 10 disposed on the bearing shaft 110 may rotate under the drive of the bearing shaft 110. It can be understood that the adhesive tape is attached to the surface of the coil 10. When the coil 10 rotates with the bearing shaft 110, the position of the adhesive tape in the first direction X and the second direction Y changes, wherein the first direction X, the second direction Y and the axial direction of the bearing shaft 110 are perpendicular to each other.

[0077] The first driving member is a member for driving the bearing shaft 110 to rotate along its own axial direction. There are many ways to connect the first driving member to the bearing shaft 110. For example, the first driving member can be directly connected to the bearing shaft 110, or can be connected to the bearing shaft 110 by means of other structures. The first driving member can be arranged on at least one side of the bearing shaft 110 along the axial direction of the bearing shaft 110 to drive the bearing shaft 110 to rotate. It should be noted that there are many structures of the first driving member. For example, the first driving member can include a rotating driving member such as a driving motor and a rotating cylinder, or can also be a composite structure including a connecting rod mechanism, a cam mechanism, etc.

[0078] The detection mechanism 200 is a component for detecting the position of the adhesive tape attached to the roll material 10 in the initial state. According to the position information of the adhesive tape, the rotation speed of the bearing shaft 110, the outer diameter of the roll material 10 and other parameters, the movement time required for the adhesive tape to move from the initial position to the preset position during the rotation of the roll material 10 can be calculated, and then the bearing shaft 110 and the roll material 10 thereon are driven by the first driving member to rotate at a corresponding rotation speed for the movement time, so that the adhesive tape can be moved to the preset position, wherein the preset position is located on the side of the bearing shaft 110 facing the peeling mechanism 300 along the first direction X, and corresponds to the position of the peeling mechanism 300 along the second direction Y.

[0079] The structure of the detection mechanism 200 can be various. For example, the detection mechanism 200 can be a CCD camera (Charge Coupled Device), an IV4 camera, etc., or a combination of the above cameras and other sensing components. For example, the detection mechanism 200 can be a combination of an IV4 camera and a color mark sensor. Among them, a CCD camera is a digital camera with a charge coupled device image sensor, which has many neatly arranged capacitors that can sense light and convert images into digital signals. An IV4 camera is an industrial camera equipped with an AI image recognition sensor, which includes a camera, a lighting lamp, and a controller. It can capture a large range with the "surface" of the image, and can stably detect even if the position of the target object is offset.

[0080] The detection mechanism 200 can be set in various positions. For example, the detection mechanism 200 can be set on one side of the supporting shaft 110 along the second direction Y, or, when the detection mechanism 200 is composed of the above-mentioned camera and other sensors, the camera can be set on one side of the supporting shaft 110 along the second direction Y, and the sensor can be set on the peeling mechanism 300.

[0081] The peeling mechanism 300 is a component for peeling the adhesive tape provided on the roll material 10 from the roll material 10. Optionally, when the peeling mechanism 300 peels the adhesive tape on the roll material 10, the adhesive tape can be located between the peeling mechanism 300 and the roll material 10 along the first direction X, and the adhesive tape overlaps with the projection of the peeling mechanism 300 on the roll material 10 along the first direction X, so that the peeling mechanism 300 is connected to the adhesive tape. At this time, the peeling mechanism 300 and the adhesive tape not only correspond in position along the second direction Y, but also correspond in position along the axial direction of the bearing shaft 110.

[0082] The peeling mechanism 300 is arranged on one side of the supporting shaft 110 along the first direction X. The first direction X is perpendicular to the axial direction of the supporting shaft 110 and can be one of multiple radial directions of the supporting shaft 110. Therefore, by driving the supporting shaft 110 and the roll 10 thereon to rotate through the first driving member, the position of the adhesive tape on the roll 10 in the second direction Y can be adjusted, so that the adhesive tape and the peeling mechanism 300 correspond to each other in the first direction X and the second direction Y.

[0083] At the same time, in order to make the axial position of the peeling mechanism 300 correspond to that of the adhesive tape along the load-bearing shaft 110, the axial position of the peeling mechanism 300 on the load-bearing shaft 110 can be pre-set according to the axial position of the adhesive tape on the load-bearing shaft 110; or the relative position of the load-bearing shaft 110 and the peeling mechanism 300 along the axial direction of the load-bearing shaft 110 can be set to be adjustable, and the axial position of the peeling mechanism 300 and the adhesive tape along the load-bearing shaft 110 can be made to correspond by adjusting the relative position of the load-bearing shaft 110 and the peeling mechanism 300 on the axial direction of the load-bearing shaft 110.

[0084] It should be noted that the "position correspondence" in the embodiment of the present application can be that the two components are arranged close to each other and have the same spatial position coordinates in one direction. For example, when the adhesive tape and the peeling mechanism 300 correspond in position along the second direction Y, the spatial position coordinates of the adhesive tape in the second direction Y and the spatial position coordinates of the peeling mechanism 300 in the second direction Y are the same.

[0085] There are many ways for the stripping mechanism 300 to strip the adhesive tape. For example, the stripping mechanism 300 can separate the adhesive tape from the roll material 10 by means of the driving action of the first driving member on the bearing shaft 110 and the roll material 10 thereon. Specifically, the stripping mechanism 300 can be connected to the adhesive tape to fix the position of the adhesive tape, and then the bearing shaft 110 and the roll material 10 thereon are driven to continue to rotate by the first driving member, so that the adhesive tape is separated from the roll material 10 during the rotation of the roll material 10. Alternatively, the stripping mechanism 300 can drive the adhesive tape to separate from the roll material 10 through its own movement. After the stripping mechanism 300 is connected to the adhesive tape, at least part of the stripping mechanism 300 can drive the adhesive tape to move in a direction away from the bearing shaft 110, so that the adhesive tape is separated from the roll material 10.

[0086] The structure of the peeling mechanism 300 can be various. In some examples, the peeling mechanism 300 can include a connecting component 312 such as a suction cup for connecting the adhesive tape, and further, the peeling mechanism 300 can also include a third driving member 330 for driving the connecting component 312 to move along the first direction X. Alternatively, the peeling mechanism 300 can also be other structures such as a robot.

[0087] In the above scheme, the bearing shaft 110 passes through the coil 10 along the axial direction of the coil 10 to support and fix the coil 10. The detection mechanism 200 can detect the position of the adhesive tape attached to the coil 10. On this basis, the bearing shaft 110 is driven to rotate by the first driving member, and the bearing shaft 110 drives the coil 10 to rotate, and the position of the adhesive tape attached to the coil 10 can be adjusted so that the adhesive tape corresponds to the position of the stripping mechanism 300, so that the adhesive tape is stripped from the coil 10 by the stripping mechanism 300. On the one hand, the adhesive tape can be automatically removed and the pretreatment efficiency of the coil 10 can be improved. On the other hand, the above-mentioned various automated mechanisms are used to strip the adhesive tape on the coil 10, which can effectively improve the stripping accuracy of the adhesive tape and improve the pretreatment quality of the coil 10, thereby improving the preparation yield and quality of the pole piece in the subsequent coating process, and improving the production efficiency and performance of the battery cell and battery device.

[0088] It should be noted that after the stripping mechanism 300 strips the adhesive tape from the roll 10, the first driving member can continue to drive the bearing shaft 110 and the roll 10 thereon to rotate, so that the material strip of the roll 10 is spread out, and part of the material strip of the roll 10 is released. At this time, part of the material strip extends along the second direction Y, so as to facilitate other pre-processing operations such as waste cutting, sampling, and adhesive application on the roll 10 in the subsequent process. In addition, when the pre-processing of the roll 10 is completed, the first driving member can drive the bearing shaft 110 and the roll 10 thereon to rotate in the opposite direction, so that the released roll 10 is rewound and transported to the coating device for roll change and slurry coating.

[0089] Please continue reading Figure 1 In some embodiments, the peeling mechanism 300 includes a second driving member 310 and a peeling member 320. The second driving member 310 is connected to the peeling member 320 to drive the peeling member 320 to move axially along the supporting shaft 110. The peeling member 320 is used to drive the adhesive tape to separate from the roll material 10.

[0090] The stripping member 320 is a member for stripping the adhesive tape disposed on the web 10 from the web 10. The stripping member 320 may include a connection member 312 such as a suction cup to connect with the adhesive tape. The second driving member 310 is a member for driving the stripping member 320 to move along the axial direction of the bearing shaft 110. The second driving member 310 may have a variety of structures, for example, the second driving member 310 may be a cylinder, a hydraulic cylinder, a linear guide mechanism, etc. The second driving member 310 may be directly connected to the stripping member 320, or may be connected to the stripping member 320 by means of other structures.

[0091] In the above solution, the second driving member 310 drives the stripping member 320 to move along the axial direction of the bearing shaft 110, so that the stripping member 320 and the adhesive tape on the roll material 10 in the axial direction of the bearing shaft 110 correspond to each other, so that the stripping member 320 can strip the adhesive tape. In addition, the second driving member 310 drives the stripping member 320 to move along the axial direction of the bearing shaft 110, so that the stripping member 320 can also be capable of stripping the adhesive tape at different positions of the roll material 10, thereby improving the flexibility and practicality of the stripping mechanism 300 and the efficiency of stripping the adhesive tape.

[0092] Please continue reading Figure 1 In some embodiments, the detection mechanism 200 includes a first detection member 210, which is used to detect the position of the adhesive tape in the axial direction of the bearing shaft 110 and in the second direction Y. The first direction X, the second direction Y and the axial direction of the bearing shaft 110 are perpendicular to each other.

[0093] The first detection member 210 may be a high-precision position detection component such as a CCD camera, which may be disposed on one side of the bearing shaft 110 along the second direction Y to detect the position of the adhesive tape along the axial direction of the bearing shaft 110 and the second direction Y in the initial state.

[0094] Based on parameters such as the position information of the adhesive tape along the second direction Y in the initial state, the rotation speed of the supporting shaft 110, and the outer diameter of the roll 10, the movement time required for the adhesive tape to move from the initial position to the preset position during the rotation of the roll 10 can be calculated, and then the supporting shaft 110 and the roll 10 thereon are driven by the first driving member, so that the supporting shaft 110 and the roll 10 rotate at a corresponding rotation speed for the movement time, so that the position of the adhesive tape and the peeling member 320 along the second direction Y corresponds.

[0095] Furthermore, according to the position information of the adhesive tape along the axial direction of the bearing shaft 110 in the initial state, the distance between the stripping member 320 and the adhesive tape along the axial direction of the bearing shaft 110 can be calculated, and then the stripping member 320 can be driven by the second driving member 310 to move the distance, so that the stripping member 320 and the adhesive tape along the axial direction of the bearing shaft 110 correspond to each other. Alternatively, a sensing component such as a color mark sensor for sensing the adhesive tape can be provided on the stripping member 320. When the adhesive tape is located on the side of the web 10 facing the stripping mechanism 300 along the first direction X, and the adhesive tape and the stripping mechanism 300 correspond to each other in the second direction Y, the stripping member 320 is driven by the second driving member 310 to move along the axial direction of the bearing shaft 110. During the movement, if the sensing component on the stripping member recognizes the adhesive tape on the web 10, the second driving member 310 stops driving, and at this time, the adhesive tape and the stripping member 320 correspond to each other in the axial direction of the bearing shaft 110.

[0096] In the above scheme, the detection mechanism 200 includes a first detection member 210, through which the position of the adhesive tape in the axial direction of the supporting shaft 110 and in the second direction Y can be accurately detected. On this basis, the relative positions of the adhesive tape and the peeling member 320 are adjusted by the first driving member and the second driving member 310, which can effectively improve the efficiency and accuracy of the position adjustment of the adhesive tape and the peeling member 320, and improve the success rate and efficiency of peeling the adhesive tape by the peeling member 320.

[0097] In some embodiments, the detection mechanism 200 further includes a second detection member, which is disposed on the peeling member 320 and is used to identify the adhesive tape during the axial movement of the peeling member 320 along the bearing shaft 110 .

[0098] The second detection member is disposed on the stripping member 320 and is a sensing component for identifying the adhesive tape during the axial movement of the stripping member 320 along the bearing shaft 110. The second detection member can have various structures, for example, the second detection member can be a color mark sensor, or the second detection member can also be an image recognition sensor, etc.

[0099] It can be understood that when the adhesive tape is located on the side of the roll 10 toward the peeling mechanism 300 along the first direction X, and the adhesive tape corresponds to the peeling mechanism 300 along the second direction Y, the peeling member 320 and the second detection member thereon are driven by the second driving member 310 to move axially along the supporting shaft 110. During the movement, if the second detection member identifies the adhesive tape on the roll 10, the second driving member 310 stops driving. At this time, the axial positions of the adhesive tape and the peeling member 320 along the supporting shaft 110 correspond.

[0100] In the above scheme, on the basis of detecting the position of the adhesive tape along the axial direction and the second direction Y of the load-bearing shaft 110 by the first detection member 210, the adhesive tape is identified by the second detection member during the axial movement of the stripping member 320 along the load-bearing shaft 110, thereby improving the position accuracy of the stripping member 320 and the adhesive tape in the axial direction of the load-bearing shaft 110, further improving the success rate of stripping the adhesive tape by the stripping member 320 and the pre-processing quality of the roll material 10.

[0101] See also Figure 2 In some embodiments, there are multiple stripping members 320 , and the multiple stripping members 320 are arranged along the axial direction of the bearing shaft 110 .

[0102] In order to improve the fixing effect of the roll material 10, there are usually multiple adhesive tapes on the roll material 10. The number of the peeling members 320 can be flexibly set according to actual conditions. For example, the number of the peeling members 320 can be set to correspond to the number of adhesive tapes on the roll material 10, so that the multiple adhesive tapes on the roll material 10 can be peeled off one by one by the multiple peeling members 320.

[0103] It is understandable that when multiple adhesive tapes are peeled off by a peeling piece 320, after the peeling piece 320 peels off the first adhesive tape, in order to improve the success rate of peeling off subsequent adhesive tapes, it is usually necessary to remove the first adhesive tape connected to the peeling piece 320, and then continue to peel off the subsequent adhesive tapes. However, the cleaning action of removing the adhesive tape from the peeling piece 320 takes a certain amount of time, resulting in low peeling efficiency.

[0104] In order to solve this problem, this embodiment provides multiple peeling members 320 to peel off multiple adhesive tapes on the roll material 10 respectively. Compared with peeling off multiple adhesive tapes by one peeling member 320, the execution of the above-mentioned cleaning action can be reduced or even eliminated, thereby effectively improving the peeling efficiency of the adhesive tape.

[0105] In addition, by using multiple peeling members 320 to peel off multiple adhesive tapes on the roll material 10 respectively, the average working time of each peeling member 320 can be reduced, and the risk of damage to the peeling member 320 can be reduced.

[0106] In the above scheme, multiple adhesive tapes on the roll material 10 are peeled off by multiple peeling members 320 , which can improve the peeling efficiency of the adhesive tapes on one hand, and reduce the risk of damage to the peeling members 320 on the other hand, thereby increasing the service life of the peeling mechanism 300 .

[0107] In some embodiments, the second driving member 310 is detachably connected to each stripping member 320 , and the second driving member 310 is used to drive at least one stripping member 320 to move along the axial direction of the bearing shaft 110 .

[0108] There are many ways to detachably connect the second driving member 310 and the stripping member 320, such as by snapping. The second driving member 310 can be detachably connected to the stripping member 320 directly or by other intermediate structures.

[0109] When a stripping piece 320 is required to strip a piece of adhesive tape, the second driving member 310 can be connected to the stripping piece 320 to drive the stripping piece 320 to move along the axial direction of the bearing shaft 110, and the second driving member 310 can be separated from at least part of the remaining stripping pieces 320. It can be understood that when a stripping piece 320 is connected to the second driving member 310 and moves under the drive of the second driving member 310, if another stripping piece 320 is provided on one side of the stripping piece 320 in the moving direction, the stripping piece 320 will also push the other stripping piece 320 to move together, and the other stripping piece 320 is equivalent to being indirectly connected to the second driving member 310 through the stripping piece 320. Exemplarily, when there are three stripping pieces 320, if the second driving member 310 is connected to the middle stripping piece 320 and drives it to move, the middle stripping piece 320 will push another stripping piece 320 in its moving direction to move together during the movement.

[0110] In the above scheme, the second driving member 310 is detachably connected to each peeling member 320. During the process of peeling the adhesive tape on the roll material 10, the second driving member 310 is connected to part of the peeling members 320 and separated from the remaining peeling members 320 to drive the part of the peeling members 320 without driving all the peeling members 320 at the same time. This can reduce the power consumption of the second driving member 310 and increase the service life of the second driving member 310.

[0111] See also Figure 2 and Figure 3In some embodiments, the second driving member 310 includes a linear module 311 and a connecting component 312, the connecting component 312 includes a main body 3121 and a rod 3122, the main body 3121 is connected to the linear module 311, and the rod 3122 is retractable relative to the main body 3121 in a direction close to or away from the stripping member 320, and is used to be engaged with or separated from the stripping member 320.

[0112] The second driving member 310 includes a linear module 311 and a connecting member 312. The linear module 311 is a member used to drive the connecting member 312 and the stripping member 320 connected to the connecting member 312 to move axially along the supporting shaft 110. The linear module 311 can be a linear guide mechanism or other linear driving members such as a cylinder and a hydraulic cylinder.

[0113] The connecting component 312 is a component used to connect the linear module 311 and the stripping member 320. The connecting component 312 is connected to the linear module 311, and moves axially along the load-bearing shaft 110 under the drive of the linear module 311. In addition, the connecting component 312 is also detachably connected to the stripping member 320, and can drive the corresponding stripping member 320 to move under the drive of the linear module 311.

[0114] The connecting component 312 can be detachably connected to the stripping member 320. Specifically, the connecting component 312 includes a main body 3121 and a rod 3122. The main body 3121 is a part of the connecting component 312 used to connect with the linear module 311. The main body 3121 can be as follows: Figure 2 and Figure 3 As shown, the rod 3122 is connected to the linear module 311 through the plate structure 313, or can be directly connected to the linear module 311. The rod 3122 is a component in the connecting component 312 for engaging with the stripping member 320. The rod 3122 is connected to the main body 3121, and can be retracted relative to the main body 3121 in a direction close to or away from the stripping member 320. When the rod 3122 is extended relative to the main body 3121 in a direction close to the stripping member 320, the rod 3122 can engage with the stripping member 320. Under the drive of the linear module 311, the rod 3122 can drive the stripping member 320 to move along the axial direction of the bearing shaft 110. When the rod 3122 is retracted relative to the main body 3121 in a direction away from the stripping member 320, the rod 3122 is separated from the corresponding stripping member 320 to achieve disassembly.

[0115] Optionally, the main body 3121 may be a driving body for driving the rod 3122 to extend or retract in a direction close to or away from the stripping member 320 . In this case, the main body 3121 and the rod 3122 may together constitute a driving component such as a driving cylinder or a hydraulic cylinder.

[0116] Optionally, except for the side of the stripping member 320 facing the bearing shaft 110 along the first direction X, the rod 3122 can be clamped into the stripping member 320 from any other side of the stripping member 320 to reduce the possibility that the rod 3122 affects the stripping effect of the stripping member 320 on the adhesive tape. It can be understood that the rod 3122 can be clamped by other structures, which are connected to the stripping member 320, and the other structures can be provided with a clamping part for clamping with the rod 3122. Of course, the clamping part for clamping with the rod 3122 can also be directly formed on the stripping member 320. The shape of the clamping part can be various, for example, the clamping part can be a hole-shaped structure or a groove-shaped structure. When the clamping part is a groove-shaped structure, except for the side of the stripping member 320 facing the bearing shaft 110 along the first direction X, the clamping part can be located at any other side of the stripping member 320, and the rod 3122 of the second driving member 310 can be clamped into the clamping part from this side. When the clamping portion is a hole-shaped structure, the clamping portion can extend from one side of the stripping member 320 to the other opposite side to form a through hole. For example, the clamping portion can extend from the side of the stripping member 320 away from the load-bearing shaft 110 along the first direction X to the side of the stripping member 320 toward the load-bearing shaft 110. At this time, the rod portion 3122 is located on the side of the stripping member 320 away from the load-bearing shaft 110 along the first direction X, and is inserted into the clamping portion from the side of the stripping member 320 away from the load-bearing shaft 110 along the first direction X.

[0117] In the above scheme, the linear module 311 is detachably connected to the stripping member 320 through the connecting member 312 to drive the stripping member 320 to move axially along the bearing shaft 110. The connecting member 312 includes a main body 3121 and a rod 3122. The main body 3121 is connected to the linear module 311. The rod 3122 is retractably arranged relative to the main body 3121 in a direction close to or away from the stripping member 320. It can be clamped in the clamping part of the stripping member 320 or separated from the clamping part, thereby realizing a detachable connection with the stripping member 320. The structure is simple and the operation is convenient.

[0118] Please continue reading Figure 2 and Figure 3 In some embodiments, the peeling mechanism 300 further includes a third driving member 330, and the second driving member 310 is connected to the peeling member 320 through the third driving member 330, and the third driving member 330 is used to drive the peeling member 320 to move along the first direction X.

[0119] The third driving member 330 is a member for driving the stripping member 320 to move toward or away from the side of the bearing shaft 110 along the first direction X. The third driving member 330 can have various structures, for example, the third driving member 330 can be a cylinder, a hydraulic cylinder, etc. When there are multiple stripping members 320, there are multiple third driving members 330, and multiple third driving members 330 are connected to multiple stripping members 320 one-to-one to drive multiple stripping members 320 separately. The third driving member 330 can be connected between the second driving member 310 and the stripping member 320, and the second driving member 310 can be detachably connected to the third driving member 330, thereby realizing a detachable connection with the corresponding stripping member 320. When the second driving member 310 includes a linear module 311 and a connecting member 312, and the connecting member 312 includes a main body 3121 and a rod portion 3122, a clamping portion for clamping with the rod portion 3122 can be formed on the third driving member 330, and the rod portion 3122 of the second driving member 310 can be clamped with the clamping portion on the third driving member 330, so as to achieve clamping with the corresponding stripping member 320.

[0120] In the above scheme, when the stripping member 320 corresponds to the adhesive tape on the roll material 10 along the axial direction of the load-bearing shaft 110 and the second direction Y, the stripping member 320 is driven by the third driving member 330 to move along the first direction X toward the side close to the load-bearing shaft 110, which can shorten the distance between the stripping member 320 and the corresponding adhesive tape along the first direction X, reduce the difficulty of connecting the stripping member 320 with the corresponding adhesive tape, and facilitate the connection between the stripping member 320 and the adhesive tape, thereby driving the adhesive tape to be peeled off from the roll material 10.

[0121] Please continue reading Figure 3 In some embodiments, the roll material processing device further includes a glue sticking mechanism 400 , which is disposed on one side of the bearing shaft 110 along the first direction X and is used to stick a glue onto the surface of the roll material 10 .

[0122] The glue sticking mechanism 400 is a component for sticking glue to the surface of the web 10. The glue sticking mechanism 400 and the peeling mechanism 300 are both arranged on one side of the bearing shaft 110 along the first direction X. The glue sticking mechanism 400 can be arranged on one side of the peeling mechanism 300 along the axial direction of the bearing shaft 110, or the glue sticking mechanism 400 can be arranged as follows. Figure 3 The arrangement shown is on a peeling mechanism 300 .

[0123] The structure of the glue sticking mechanism 400 can be various. For example, the glue sticking mechanism 400 can include a glue sticking assembly 430. The glue sticking assembly 430 includes a fourth driving member and a glue sticking member 431 connected to the fourth driving member. The glue sticking member 431 can move along the first direction X toward the side close to the bearing shaft 110 under the drive of the fourth driving member to stick glue to the surface of the coil 10. Furthermore, the glue sticking mechanism 400 can also include at least one of other structures such as an unwinding assembly 410, a winding assembly 420 and a glue cutting assembly to improve the performance of the glue sticking mechanism 400.

[0124] In the above scheme, after the adhesive tape on the coil 10 is peeled off by the peeling mechanism 300, the adhesive is attached to the surface of the coil 10 by the adhesive attaching mechanism 400, so that the automatic adhesive attaching of the coil 10 can be realized without manual adhesive attaching to the coil 10, which can further improve the processing efficiency and processing accuracy of the coil 10, and help improve the preparation yield and quality of the electrode in the subsequent coating process. The adhesive-attached coil 10 can be bonded to the coil 10 to be replaced in the coating device when it is transported to the coating device, thereby realizing the coil replacement of the coating device.

[0125] In some embodiments, the glue applying mechanism 400 is movably disposed along the axial direction of the bearing shaft 110 .

[0126] Specifically, when the stripping mechanism 300 includes a stripping member 320 and a second driving member 310, the gluing mechanism 400 may be connected to the second driving member 310 or the stripping member 320 to move along the axial direction of the bearing shaft 110 under the drive of the second driving member 310. Alternatively, other linear driving structures may be provided in the coil processing device to drive the gluing mechanism 400.

[0127] In the above scheme, the gluing mechanism 400 is movably arranged along the axial direction of the load-bearing shaft 110. During the axial movement of the gluing mechanism 400 along the load-bearing shaft 110, the gluing mechanism 400 can continuously apply glue to the surface of the roll 10 to increase the glue area on the roll 10, thereby improving the reliability of roll changing.

[0128] In some embodiments, the gluing mechanism 400 is disposed on the peeling mechanism 300 .

[0129] Specifically, when the stripping mechanism 300 includes the second driving member 310 and the stripping member 320, the gluing mechanism 400 can be connected to the second driving member 310 to move along the axial direction of the bearing shaft 110 under the drive of the second driving member 310. When the second driving member 310 includes a linear module 311 and a connecting member 312, and the connecting member 312 is connected to the linear module 311 through a plate structure 313, the gluing mechanism 400 can be arranged on the plate structure 313, and connected to the linear module 311 through the plate structure 313, and the structure of the coil processing device is made more compact.

[0130] In the above scheme, the gluing mechanism 400 is arranged on the peeling mechanism 300. On the one hand, it can make the structure of the roll material processing device more compact and reduce the volume of the roll material processing device. On the other hand, when the peeling mechanism 300 includes a second driving member 310 and a peeling member 320, the second driving member 310 can also drive the gluing mechanism 400 to move axially along the load-bearing shaft 110, thereby eliminating the need to additionally set up a driving component for driving the gluing mechanism 400 separately, thereby simplifying the structure of the roll material processing device and reducing the production cost of the roll material processing device.

[0131] See also Figure 4 and Figure 5 In some embodiments, the gluing mechanism 400 includes a unwinding component 410, a rewinding component 420 and a gluing component 430. The unwinding component 410 is used to set the tape roll 20, and the tape roll 20 includes a substrate 21 and a colloid arranged on the surface of the substrate 21; the rewinding component 420 is used to rewind the substrate 21; the gluing component 430 includes a fourth driving member and a gluing member 431 connected to the fourth driving member, the fourth driving member is used to drive the gluing member 431 to move along the first direction X, and the gluing member 431 is used to push the substrate 21 along the first direction X so that the colloid on the substrate 21 is attached to the surface of the roll 10.

[0132] The unwinding assembly 410 is a component for setting the tape roll 20 and unwinding it to the adhesive member 431 of the adhesive member 430. The structure of the unwinding assembly 410 can be various. The unwinding assembly 410 can be a mechanical unwinding component. For example, the unwinding assembly 410 can include a first reel, and the tape roll 20 is arranged on the first reel. When the adhesive member 431 pushes the substrate 21 in the first direction X toward the direction close to the bearing shaft 110, the substrate 21 drives the first reel to rotate, the tape roll 20 spreads, and the substrate 21 stretches, thereby achieving unwinding. Alternatively, the unwinding assembly 410 can be an automatic unwinding component. For example, the unwinding assembly 410 can include a first reel and a first rotating drive structure. The tape roll 20 is arranged on the first reel. The first rotating drive structure can be a rotating drive component such as a driving motor. The first rotating drive structure is connected to the first reel, and is used to drive the first reel to rotate when the adhesive member 431 pushes the substrate 21 to move. The first reel drives the tape roll 20 to be released, so that the substrate 21 stretches, and automatic unwinding is achieved.

[0133] The glue sticking assembly 430 is a component used to stick the glue on the substrate 21 of the tape roll 20 to the surface of the coil 10. The glue sticking assembly 430 includes a fourth driving member and a glue sticking member 431. The fourth driving member is used to drive the glue sticking member 431 to move along the first direction X. The fourth driving member can be a linear driving member such as a cylinder or a hydraulic cylinder. The glue sticking member 431 is used to push the substrate 21 along the first direction X under the drive of the fourth driving member so that the glue on the substrate 21 is attached to the surface of the coil 10.

[0134] The shape of the glue sticking member 431 can be various, for example, the glue sticking member 431 can be a cylindrical glue sticking roller, or the glue sticking member 431 can also be a plate-like structure. In some optional embodiments, the glue sticking member 431 is a glue sticking roller, and the axis of the glue sticking roller can extend along the second direction Y, which is perpendicular to the axial direction of the bearing shaft 110 and the first direction X at the same time. Therefore, during the process of the glue sticking mechanism 400 moving along the axial direction of the bearing shaft 110, the glue sticking roller rolls, which can better adhere the glue to the surface of the coil 10 on the one hand, and can also reduce the friction loss between it and the coil 10 on the other hand.

[0135] The winding assembly 420 is a component for winding the corresponding substrate 21 after the adhesive sticking member 431 attaches the adhesive on the surface of the substrate 21 to the surface of the roll 10. The structure of the winding assembly 420 can be various. The winding assembly 420 can be a mechanical winding component. For example, the winding assembly 420 can include a second reel. The second reel can be connected to the first reel of the unwinding assembly 410 through a belt drive, a chain drive, or a gear meshing drive, so as to rotate under the drive of the first reel. The second reel is fixedly connected to the substrate 21 of the tape roll 20, and is used to wind up the corresponding substrate 21 during the rotation process. Alternatively, the winding assembly 420 can be an automatic winding component. For example, the winding assembly 420 can include a second reel and a second rotation drive structure. The second reel is connected to the substrate 21, and the second rotation drive structure is connected to the second reel. The second rotation drive structure can be a rotation drive component such as a drive motor, which is used to drive the second reel to rotate after the adhesive on the substrate 21 is bonded to the surface of the roll 10, so as to realize automatic winding of the corresponding substrate 21.

[0136] The tape roll 20 is arranged in the unwinding component 410, and its substrate 21 passes through the glue-applying component 431 along the first direction X toward the side surface of the load-bearing shaft 110, and extends to be connected with the winding component 420. When the glue-applying component 431 moves toward the side close to the load-bearing shaft 110 under the drive of the fourth driving component, the unwinding component 410 releases the tape roll 20, and the substrate 21 of the tape roll 20 is stretched. The substrate 21 moves toward the direction close to the load-bearing shaft 110 under the push of the glue-applying component 431, and the colloid located on the surface of the substrate 21 is adhered to the surface of the coil 10 on the load-bearing shaft 110. At the same time, the winding component 420 winds up the substrate 21 separated from the colloid. It can be understood that when the substrate 21 passes through the side surface of the adhesive component 431 along the first direction X toward the load-bearing shaft 110, the colloid is located on the side of the substrate 21 away from the adhesive component 431 along the first direction X, that is, between the substrate 21 and the load-bearing shaft 110. Therefore, under the push of the adhesive component 431, the colloid on the surface of the substrate 21 can be bonded to the surface of the coil 10.

[0137] In the above scheme, the unwinding component 410 is used to set the tape roll 20, which can unwind to the glue sticking member 431 of the glue sticking component 430. The glue sticking member 431 can push the substrate 21 of the tape roll 20 to move along the first direction X toward the side close to the bearing shaft 110 under the drive of the fourth driving member, so that the colloid on the surface of the substrate 21 contacts and adheres to the surface of the coil 10, thereby realizing automatic gluing of the coil 10. When the colloid is adhered to the surface of the coil 10, the substrate 21 is separated from the corresponding colloid, and then the separated substrate 21 is automatically rewound by the rewinding component 420 without manual recovery of the substrate 21, which can improve the automation degree of the coil processing device and further improve the processing efficiency of the coil 10.

[0138] Please continue reading Figure 4 and Figure 5 In some embodiments, the gluing mechanism 400 is movably arranged along the axial direction of the load-bearing shaft 110, the gluing member 431 includes an incoming side and an outgoing side relatively arranged along the axial direction of the load-bearing shaft 110, the unwinding component 410 unwinds from the incoming side through the gluing member 431 toward one side surface of the load-bearing shaft 110 in the direction of the outgoing side, the gluing mechanism 400 also includes a re-pressing component 440, the re-pressing component 440 is arranged on the outgoing side of the gluing member 431, the re-pressing component 440 includes a fifth driving member and a re-pressing component 441 connected to the fifth driving member, the fifth driving member is used to drive the re-pressing component 441 to move along the first direction X, and the re-pressing component 441 is used to press the roll material 10 and the colloid attached to the surface of the roll material 10 along the first direction X.

[0139] The incoming material side is the substrate 21 of the tape roll 20 extending from the unwinding assembly 410 to the side of the surface of the adhesive member 431 facing the bearing shaft 110, and the outgoing material side is the substrate 21 of the tape roll 20 extending from the surface of the adhesive member 431 facing the bearing shaft 110 to the side of the rewinding assembly 420. The unwinding assembly 410 unwinds from the incoming material side through the adhesive member 431 toward the side of the bearing shaft 110 toward the outgoing material side, that is, the substrate 21 of the tape roll 20 extends from the incoming material side through the adhesive member 431 toward the surface of the bearing shaft 110, and extends to the unwinding assembly 410 through the outgoing material side.

[0140] It can be understood that, in the axial direction of the bearing shaft 110, the gluing mechanism 400 moves from the material-incoming side to the material-outgoing side, so that the colloid on the substrate 21 is continuously bonded to the surface of the coil 10 during the movement. Specifically, before the gluing mechanism 400 moves, the fourth driving member drives the gluing member 431 to move along the first direction X toward the side close to the bearing shaft 110, and the gluing member 431 pushes the substrate 21, so that the colloid on the surface of the substrate 21 contacts the surface of the coil 10, and then the gluing mechanism 400 is controlled to move along the axial direction of the bearing shaft 110. During the movement, the unwinding assembly 410 continuously unwinds toward the gluing member 431, and the gluing member 431 continuously presses the colloid on the substrate 21 toward the coil 10, and at the same time, the rewinding assembly 420 continuously rewinds the corresponding substrate 21, so that the surface of the coil 10 is attached with the colloid extending along the axial direction of the bearing shaft 110.

[0141] The re-pressing component 440 is a component used to re-press the colloid after the colloid is attached to the surface of the coil 10 during the axial movement along the bearing shaft 110. The re-pressing component 440 is arranged on the discharge side of the glue sticking member 431. During the movement of the glue sticking mechanism 400 from the incoming material side to the discharge side, the glue sticking member 431 and the re-pressing component 440 successively pass through the glue sticking area of ​​the coil 10. The glue sticking member 431 first presses the colloid on the substrate 21 toward the coil 10, so that the colloid adheres to the glue sticking area of ​​the coil 10. Then, the re-pressing component 440 passes through the glue sticking area and re-presses the colloid in the glue sticking area, so that the colloid is tightly combined with the coil 10.

[0142] The re-pressing assembly 440 includes a fifth driving member and a re-pressing member 441. The fifth driving member may be a linear driving member such as a cylinder or a hydraulic cylinder. The re-pressing member 441 may move along the first direction X toward the side close to the bearing shaft 110 under the drive of the fifth driving member. During the axial movement of the gluing mechanism 400 along the bearing shaft 110, the re-pressing member 441 may re-press the colloid bonded to the gluing area of ​​the coil 10. The re-pressing member 441 may have a variety of shapes, for example, the re-pressing member 441 may be a plate structure 313, or a cylindrical roller 1100 structure.

[0143] In the above scheme, the unwinding component 410 unwinds from the incoming material side through the glue sticking component 431 toward the side surface of the load-bearing shaft 110, and toward the discharge side. That is, the substrate 21 of the tape roll 20 passes through the glue sticking component 431 from the incoming material side toward the side surface of the load-bearing shaft 110, and extends toward the discharge side. The colloid on the surface of the substrate 21 is located on the side of the substrate 21 away from the glue sticking component 431. When the fourth driving component drives the glue sticking component 431 to move along the first direction X toward the side close to the load-bearing shaft 110, the colloid on the surface of the substrate 21 can contact and bond with the surface of the coil 10 on the load-bearing shaft 110, thereby realizing automatic gluing of the coil 10. On this basis, a re-pressing component 440 is arranged on the discharge side of the glue-applying member 431. The re-pressing component 440 includes a fifth driving member and a re-pressing member 441. The re-pressing member 441 can be moved along the first direction X toward the bearing shaft 110 under the drive of the fifth driving member. When the glue-applying member 431 pushes the substrate 21 so that the glue on its surface is attached to the surface of the coil 10, during the axial movement of the glue-applying mechanism 400 along the bearing shaft 110, the re-pressing member 441 can press the coil 10 and the glue attached to its surface along the first direction X, so that the contact between the glue and the coil 10 is closer.

[0144] In some embodiments, the glue sticking mechanism 400 further includes a glue cutting assembly, which is disposed on the incoming material side of the glue sticking member 431 and is used to cut off the glue.

[0145] The glue cutting assembly is a component used to cut the glue along the length direction of the substrate 21 when the roll material 10 is about to be glued, so that the glue attached to the roll material 10 is disconnected from the glue on the surface of the substrate 21. The glue cutting assembly cuts the glue on the incoming side of the glue sticking member 431. After the glue is cut, the glue on the side of the glue sticking member 431 facing the bearing shaft 110 continues to be attached to the surface of the roll material 10 under the action of the glue sticking member 431, and then the glue sticking is completed.

[0146] It should be noted that the adhesive cutting assembly can be separated from the substrate 21 during the process of cutting the adhesive, thereby reducing the risk of the substrate 21 being cut by the adhesive cutting assembly and requiring manual reassembly of the tape roll 20 .

[0147] The structure of the rubber cutting assembly can be various. For example, the rubber cutting assembly can be formed by combining a cutting blade and a reciprocating swinging structure, and the reciprocating swinging structure drives the cutting blade to swing to cut the colloid and reset it after cutting. Alternatively, the rubber cutting assembly can also be formed by combining a cutting blade and a linear drive structure, and the linear drive structure drives the cutting blade to make a linear reciprocating motion to cut the colloid and reset it after cutting.

[0148] In the above scheme, the glue cutting component can cut the glue after the roll material 10 is about to be glued, so that the glue attached to the roll material 10 is disconnected from the glue on the surface of the substrate 21 without manual glue cutting, which can further improve the degree of automation of the roll material processing device and further improve the processing efficiency of the roll material 10.

[0149] In some optional embodiments, the coil material processing device may further include a control terminal, which is used to control the operation of the first driving member, the stripping mechanism 300, the gluing mechanism 400 and other structures. For example, in the process of driving the gluing mechanism 400 to move axially along the bearing shaft 110 by the second driving member 310, the control terminal may control the gluing starting point, end point and gluing speed of the gluing mechanism 400 through the second driving member 310 to adapt to coil materials 10 of different specifications. In addition, the control terminal can also alarm when the tape roll 20 in the gluing mechanism 400 is exhausted, so as to remind the operator to load the material without repeated manual inspection.

[0150] Please continue reading Figures 6 to 8 In some embodiments, the roll material processing device also includes a machine base 500, the machine base 500 includes a machine base body 510 and a driving component 520 arranged on the machine base body 510, the supporting mechanism 100, the detection mechanism 200 and the peeling mechanism 300 are integrated on the machine base body 510, and the driving component 520 is used to drive the machine base body 510 to move toward the coating device.

[0151] The base 500 includes a base body 510 and a driving assembly 520. The base body 510 is a component for supporting structures such as the bearing mechanism 100, the detection mechanism 200 and the stripping mechanism 300. The bearing mechanism 100, the detection mechanism 200 and the stripping mechanism 300 are all arranged on the base body 510, which can improve the structural compactness of the web processing device. The driving assembly 520 is connected to the base body 510 and is a component for driving the base body to move toward the coating device.

[0152] The structure of the driving component 520 can be various. For example, the driving component 520 can be a combination structure of a driving wheel 521 and a driven wheel 522, or the driving component 520 can be a guide rail structure, a screw rod structure, etc.

[0153] In some optional embodiments, when the coil material processing device includes the gluing mechanism 400, the gluing mechanism 400 is integrated on the base body 510, so that the structure of the coil material processing device is more compact.

[0154] In the above scheme, the supporting mechanism 100, the detection mechanism 200 and the stripping mechanism 300 are integrated in the base body 510. After the pre-processing of the coil 10 on the supporting mechanism 100 is completed, the base body 510 is driven by the driving component 520 to move toward the coating device, and the processed coil 10 can be transported to the coating device to facilitate the processes such as coil changing and slurry coating of the coating device.

[0155] It should be noted that the driving assembly 520 can drive the base body 510 and the structure thereon to move between a plurality of coating devices, and transport the pre-treated web 10 to each coating device.

[0156] Please continue reading Figure 7 In some embodiments, the base 500 further includes a magnetic navigation sensor 530 for guiding the movement of the base body 510 .

[0157] The magnetic navigation sensor 530 is a component used to sense the buried magnetic strip to guide the base body 510 when the driving assembly 520 drives the base body 510 to move, so that the base body 510 moves according to the preset moving route. The buried magnetic strip is a magnetic induction component pre-buried in the ground, and the extension direction of the buried magnetic strip is the extension direction of the preset moving route.

[0158] Optionally, the magnetic navigation sensor 530 can be set on the side of the base body 510 facing away from the drive assembly 520. When the coil processing device is set on the ground, the magnetic navigation sensor 530 is located on the side of the base body 510 facing away from the ground. At this time, the base body 510 can have an opening to expose the magnetic navigation sensor 530, thereby reducing the risk of interference between the magnetic navigation sensor 530 and other objects during movement.

[0159] In the above scheme, the buried magnetic strip is sensed by the magnetic navigation sensor 530 to guide the base body 510 when the driving component 520 drives the base body 510 to move, thereby reducing the risk of the base body 510 deviating from the preset moving route and improving the conveying efficiency of the coil 10.

[0160] Please continue reading Figure 7 In some embodiments, the driving assembly 520 includes at least one driving wheel 521 and at least one driven wheel 522. The driving wheel 521 and the driven wheel 522 are spaced apart and located on the side of the base body 510 away from the peeling mechanism 300. The driving wheel 521 is used to drive the base body 510 to move.

[0161] The driving wheel 521 is a component used to drive the machine base body 510 to move. The driving wheel 521 can be an active steering wheel or other wheel structure with driving capability. The driving wheel 521 is arranged on the side of the machine base body 510 away from the peeling mechanism 300, that is, on the side of the machine base body 510 facing the ground. There can be multiple driving wheels 521, and multiple driving wheels 521 are arranged at intervals on the surface of the side of the machine base body 510 away from the peeling mechanism 300.

[0162] The driven wheel 522 is a component used to be arranged on the same side of the base body 510 as the driving wheel 521 to assist the movement of the base body 510. The driven wheel 522 is arranged at an interval from the driving wheel 521. When the base body 510 moves driven by the driving wheel 521, the driven wheel 522 supports the base body 510 during the movement of the base body 510, thereby improving the stability of the base body 510. At the same time, the driven wheel 522 rolls driven by the base body 510, thereby reducing friction. Optionally, the driven wheel 522 can be a universal wheel to improve its flexibility.

[0163] The number of driven wheels 522 may be one or more. When the number of driven wheels 522 is more than one, the multiple driven wheels 522 are spaced apart on the surface of the side of the base body 510 away from the peeling mechanism 300. Exemplarily, the driving assembly 520 may include two driving wheels 521 and two driven wheels 522, and the driving wheels 521 and the driven wheels 522 are alternately distributed, wherein the two driving wheels 521 are diagonally distributed, and the two driven wheels 522 are diagonally distributed.

[0164] In the above scheme, the driving wheel 521 and the driven wheel 522 are both arranged on the side of the base body 510 away from the peeling mechanism 300, that is, on the side of the base body 510 facing the ground. The driving wheel 521 drives the base body 510 to move, which can improve the stability of the base body 510 during the movement and reduce the overall volume of the driving assembly 520. In addition, during the movement of the base body 510, the driven wheel 522 rotates under the drive of the base body 510, which can assist the driving wheel 521 to further improve the stability of the base body 510.

[0165] Please continue reading Figure 8 In some embodiments, the base body 510 includes a supporting plate 511, a first bracket 512 and a sixth driving member 513. The first bracket 512 is connected to the supporting plate 511 through the sixth driving member 513. The sixth driving member 513 is used to drive the first bracket 512 to move along the first direction X relative to the supporting plate 511. The peeling mechanism 300 is arranged on the first bracket 512.

[0166] The bearing plate 511 is a component in the base body 510 for supporting structures such as the bearing mechanism 100, the detection mechanism 200, the first bracket 512, and the peeling mechanism 300 on the first bracket 512. Optionally, the base body 510 further includes a second bracket, which is disposed on the bearing plate 511, and the bearing mechanism 100 and at least part of the detection mechanism 200 can be connected to the bearing plate 511 through the second bracket.

[0167] The first bracket 512 is a component for supporting the peeling mechanism 300. When the web processing device includes a gluing mechanism 400, the first bracket 512 is also used to support the gluing mechanism 400. The first bracket 512 is connected to the carrier plate 511 through the sixth driving member 513, and can move along the first direction X under the drive of the sixth driving member 513.

[0168] The sixth driving member 513 is a member for connecting the first bracket 512 and the carrier plate 511, and driving the first bracket 512, so that the first bracket 512 moves relative to the carrier plate 511 along the first direction X. The sixth driving member 513 may have a variety of structures, for example, the sixth driving member 513 may be a linear guide structure, or may be other linear driving members such as a screw rod structure.

[0169] In the above scheme, the first bracket 512 is connected to the carrying plate 511 through the sixth driving member 513, and the stripping mechanism 300 is arranged on the first bracket 512. When it is necessary to strip the adhesive tape on the roll material 10 on the bearing shaft 110 through the stripping mechanism 300, the first bracket 512 is driven by the sixth driving member 513 to move along the first direction X toward the side close to the bearing shaft 110, which can shorten the distance between the stripping mechanism 300 and the roll material 10, so as to reduce the difficulty of the stripping mechanism 300 stripping the adhesive tape on the surface of the roll material 10. When it is not necessary to work through the stripping mechanism 300, the first bracket 512 is driven by the sixth driving member 513 to move along the first direction X toward the side away from the bearing shaft 110, which can increase the distance between the bearing shaft 110 and the stripping mechanism 300 and the first bracket 512, so that there is sufficient space around the bearing shaft 110 for realizing other operations such as assembly or disassembly of the roll material 10.

[0170] See also Fig. 9 In some embodiments, the roll material processing device also includes a sample storage bin 600 and a tape cutting mechanism 700. The tape cutting mechanism 700 is arranged on one side of the stripping mechanism 300 along the second direction Y. The sample storage bin 600 is arranged on the side of the tape cutting mechanism 700 away from the stripping mechanism 300 along the second direction Y. The opening of the sample storage bin 600 faces the tape cutting mechanism 700.

[0171] The tape cutting mechanism 700 is a component used to cut the released tape of the coil 10 after the coil 10 is spread out, so as to separate it from the remaining tape of the coil 10. The tape cutting mechanism 700 is arranged on one side of the stripping mechanism 300 along the second direction Y. When the tape of the coil 10 is partially released, the tape cutting mechanism 700 and the released tape are located on the same side of the stripping mechanism 300 along the second direction Y, so as to facilitate cutting of the partially released tape.

[0172] There are various structures of the tape cutting mechanism 700. The tape cutting mechanism 700 may include a cutter and an eighth driving member 710 for driving the cutter to move axially along the load-bearing shaft 110, and the cutter cuts the material tape during the axial movement along the load-bearing shaft 110; or, the tape cutting mechanism 700 may also include a cutter and a driving structure for driving the cutter to move along the first direction X, and the cutter cuts the material tape during the movement along the first direction X. At this time, the axial length of the cutter along the load-bearing shaft 110 is greater than or equal to the axial width of the material tape of the coil 10 along the load-bearing shaft 110.

[0173] The sample storage bin 600 is a component provided with a sample cavity and an opening connected to the sample cavity, and is used to store samples of the coil 10. The sample storage bin 600 is arranged on the side of the tape cutting mechanism 700 away from the peeling mechanism 300 along the second direction Y, and its opening faces the tape cutting mechanism 700. When the tape cutting mechanism 700 cuts part of the tape of the coil 10, the cut part of the tape enters the sample storage bin 600 through the opening.

[0174] It should be noted that when the base 500 includes a base body 510 , and the base body 510 includes a supporting plate 511 , a first bracket 512 and a sixth driving member 513 , the sample storage chamber 600 and the tape cutting mechanism 700 can both be disposed on the first bracket 512 .

[0175] In the above scheme, the tape cutting mechanism 700 is arranged on one side of the stripping mechanism 300 along the second direction Y. After the stripping mechanism 300 strips the adhesive tape on the roll material 10, the first driving member drives the supporting shaft 110 to rotate, so that the roll material 10 can be spread out, and part of the tape of the roll material 10 is released. The released tape stretches along the second direction Y toward the direction close to the tape cutting mechanism 700, so that the tape is cut by the tape cutting mechanism 700, so that part of the tape is separated from the roll material 10. Since the sample storage bin 600 is arranged on the side of the tape cutting mechanism 700 away from the stripping mechanism 300 along the second direction Y, and the opening of the sample storage bin 600 faces the tape cutting mechanism 700, the tape cut by the tape cutting mechanism 700 can enter the sample storage bin 600 through the opening for storage, thereby realizing automatic sampling of the roll material 10, which can further improve the degree of automation of the roll material processing device and further improve the processing efficiency of the roll material 10.

[0176] In some embodiments, the sample storage chamber 600 includes a chamber body and a seventh driving member connected to the chamber body, and the seventh driving member is used to drive the chamber body to move along the first direction X.

[0177] The bin body is a component in the sample storage bin 600 for storing the sample of the coil 10, and the bin body may be provided with a containing cavity and an opening, wherein the opening of the bin body faces the tape cutting mechanism 700. The seventh driving member is a component for driving the bin body so that the bin body can move along the first direction X. The seventh driving member may be a component for driving the bin body to move in a straight line in the first direction X. The structure of the seventh driving member may be various, for example, the seventh driving member may be a driving member such as a linear guide structure, a cylinder or a hydraulic cylinder. Alternatively, the seventh driving member may also drive the bin body to swing around the axially extending axis of the bearing shaft 110, in which case the bin body is equivalent to moving in the first direction X and the second direction Y at the same time, for example, the seventh driving member may be a driving motor.

[0178] In the above scheme, when the coil 10 needs to be sampled, the seventh driving member drives the bin body to move along the first direction X toward the side close to the bearing shaft 110, so that the bin body extends out, and the opening of the bin body corresponds to the position of the tape cutting mechanism 700 along the first direction X, so that the tape cut by the tape cutting mechanism 700 can enter the sample storage bin 600 through the opening. When the coil 10 does not need to be sampled, the seventh driving member drives the bin body to move along the first direction X toward the side away from the bearing shaft 110, so that the bin body is retracted, which can reduce the risk of mutual interference between the bin body and other structures of the coil 10 processing mechanism.

[0179] See also Fig. 9 and Fig.10 In some embodiments, the tape cutting mechanism 700 includes an eighth driving member 710, a cutter 720 and a positioning member. The eighth driving member 710 is connected to the cutter to drive the cutter to move axially along the load-bearing shaft 110. The positioning member is located on one side of the cutter along the second direction Y and is used to clamp the tape of the coil 10 along the first direction X.

[0180] The cutter is a component used to cut the material strip of the coil 10 so that the released material strip is separated from the remaining unreleased material strip. The eighth driving member 710 is connected to the cutter and is used to drive the cutter so that the cutter moves along the axial direction of the bearing shaft 110. The structure of the eighth driving member 710 can be various, for example, the eighth driving member 710 can be a linear guide structure, a cylinder or a hydraulic cylinder, etc.

[0181] The positioning member is a component used to clamp the material strip along the first direction X to position the material strip during the process of the cutter cutting the material strip. The positioning member can be a mechanical positioning structure, for example, the positioning member can include two clamping plates, and the two clamping plates are configured to be able to lock along the first direction X to position the material strip along the first direction X. Alternatively, the positioning member can also be an automated positioning structure, for example, the positioning member can include a positioning base plate, a positioning roller 1100 and a linear drive structure, the linear drive structure is connected to at least one of the positioning base plate and the positioning roller 1100, and is used to drive at least one of the positioning base plate and the positioning roller 1100 to move along the first direction X, so that the positioning base plate and the positioning roller 1100 can clamp the material strip along the first direction X.

[0182] In the above scheme, after part of the material strip of the coil 10 is released, the part of the material strip extends along the second direction Y relative to the remaining material strip on the coil 10 that has not been released, and the cutter can be located on one side of the part of the material strip along the axial direction of the bearing shaft 110, and the cutter is driven by the eighth driving member 710 to move along the axial direction of the bearing shaft 110, and the cutter can cut the material strip during the movement, so that the released part of the material strip is separated from the remaining material strip. On this basis, a positioning member is provided on one side of the cutter along the second direction Y, and in the process of cutting the material strip by the cutter, the positioning member can clamp the material strip along the first direction X to position the material strip along the first direction X, thereby reducing the risk of the material strip moving and deviating during the cutting process, and improving the cutting consistency and cutting efficiency.

[0183] Please continue reading Fig. 9 In some embodiments, the roll material processing device further includes a silo 800 , which is disposed on a side of the tape cutting mechanism 700 away from the peeling mechanism 300 along the second direction Y, and an opening of the silo 800 faces the tape cutting mechanism 700 .

[0184] It is understandable that the coil 10 is formed by winding a material strip. During the long-term storage and transportation of the coil 10, the outermost material strip of the coil 10 is exposed to the external environment, causing its performance to be affected. This part of the material strip is regarded as waste. During the pretreatment of the coil 10, the waste can be cut off, and then the coil 10 is sampled, which can ensure the accuracy and reliability of the sample. It should be noted that in addition to cutting the material strip of the coil 10 during the sampling process, the tape cutting mechanism 700 can also be used to cut off the waste of the coil 10 before sampling, so that the waste is separated from the remaining material strips of the coil 10.

[0185] The silo 800 is a component provided with a waste material receiving cavity and an opening communicating with the waste material receiving cavity, and is used to store the waste material of the outermost layer of the coil 10. The silo 800 is arranged on the side of the tape cutting mechanism 700 and away from the stripping mechanism 300 along the second direction Y, and its opening faces the tape cutting mechanism 700. When the tape cutting mechanism 700 cuts the waste material of the coil 10, the cut waste material enters the silo 800 through the opening. When the base 500 includes the base body 510, and the base body 510 includes the bearing plate 511, the first bracket 512 and the sixth driving member 513, the silo 800 can be arranged on the first bracket 512.

[0186] In the above scheme, the silo 800 can be used to store the waste material of the outermost layer of the coil 10. By arranging the silo 800 on the side of the tape cutting mechanism 700 away from the peeling mechanism 300, and the opening of the silo 800 is facing the tape cutting mechanism 700, therefore, after the waste material of the outermost layer of the coil 10 is cut off by the tape cutting mechanism 700, the waste material can enter the silo 800 through the opening of the silo 800, thereby realizing automatic cutting and recycling of the waste material, which can further improve the degree of automation of the coil processing device, further improve the processing efficiency of the coil 10, and at the same time reduce the interference of the waste material on other structures in the coil processing device.

[0187] In some embodiments, the silo 800 includes a first sub-silo, a second sub-silo, and a ninth driving member. The first sub-silo and the second sub-silo are interconnected and arranged along the first direction X. The ninth driving member is connected to at least one of the first sub-silo and the second sub-silo, and is used to drive the first sub-silo and the second sub-silo to move along the first direction X.

[0188] It is understandable that the waste material of the outermost layer of the coil 10 may be of various types, for example, the waste material may be waste material of the substrate 21 or waste material of the gravure plate.

[0189] The first sub-bin and the second sub-bin are both provided with a waste material containing cavity and an opening communicating with the waste material containing cavity. The first sub-bin and the second sub-bin are components for containing different waste materials of the coil 10. For example, the first sub-bin can be used to contain waste substrate 21 of the coil 10, and the second sub-bin can be used to contain waste gravure of the coil 10. The structures of the first sub-bin and the second sub-bin can be the same or different. The first sub-bin and the second sub-bin are connected to each other, and there are many ways to connect the two. For example, the first sub-bin and the second sub-bin can be an integrally formed structure, or the first sub-bin and the second sub-bin can also be connected by other structures.

[0190] The first sub-bin and the second sub-bin are arranged along the first direction X. Therefore, the first sub-bin and the second sub-bin are driven to move along the first direction X by the ninth driving member, so that any one of the openings of the first sub-bin and the second sub-bin can be located on one side of the tape cutting mechanism 700 along the second direction Y. After the tape cutting mechanism 700 cuts off the waste material of the coil 10, the waste material can enter the first sub-bin or the second sub-bin through the corresponding opening.

[0191] The ninth driving member is a member for driving the first sub-chamber and the second sub-chamber so that the first sub-chamber and the second sub-chamber move along the first direction X. The ninth driving member may have a variety of structures, for example, the ninth driving member may be a driving member such as a linear guide mechanism, a cylinder, a hydraulic cylinder, etc. The ninth driving member is connected to at least one of the first sub-chamber and the second sub-chamber, and may be directly connected to at least one of the first sub-chamber and the second sub-chamber, or may be connected to at least one of the first sub-chamber and the second sub-chamber by means of other structures.

[0192] In the above scheme, the first sub-bin and the second sub-bin can be used to classify and recycle different types of waste materials. The tape cutting mechanism 700 can cut the different types of waste materials on the outermost layer of the coil 10 respectively. During the cutting process, the first sub-bin and the second sub-bin are driven by the ninth driving member to move along the first direction X, so that the opening of the first sub-bin or the opening of the second sub-bin corresponds to the position of the tape cutting mechanism 700 along the first direction X, and then the different types of waste materials cut off enter the first sub-bin and the second sub-bin respectively through the corresponding openings, so as to realize the classification and recycling of different types of waste materials and reduce the mutual influence between different types of waste materials.

[0193] See also Fig.11 In some embodiments, the coil material processing device further includes a spray mechanism 900 , which is disposed on one side of the bearing shaft 110 along the second direction Y, and is used to spray liquid onto the inner surface of the material strip after the coil material 10 is released.

[0194] The spray mechanism 900 is a component for spraying liquid onto the inner surface of the tape after the coil 10 is released. The spray mechanism 900 is arranged on one side of the bearing shaft 110 along the second direction Y. When part of the tape of the coil 10 is released, the spray mechanism 900 and the released tape are located on the same side of the bearing shaft 110 along the second direction Y, so as to spray liquid onto it. It should be noted that the inner surface of the tape can be a side surface of the tape facing the central axis of the coil 10 when the coil 10 is wound. The liquid sprayed onto the tape by the spray mechanism 900 can be a liquid that can evaporate quickly, such as alcohol and deionized water.

[0195] The structure of the spray mechanism 900 can be various. For example, the spray mechanism 900 can be an injection component such as an air flow sprayer, a liquid flow sprayer, a jet sprayer, or the like. Alternatively, the spray mechanism 900 can also be a composite structure composed of a nozzle 910 and other structures.

[0196] In the above scheme, after the peeling mechanism 300 peels off the adhesive tape on the roll material 10, the first driving member drives the supporting shaft 110 to rotate, so that the roll material 10 can be spread out, and part of the material tape of the roll material 10 is released. The released material tape stretches along the second direction Y. Therefore, the liquid is sprayed on the inner surface of the released material tape through the nozzle 910 of the spray mechanism 900, and then the first driving member drives the supporting shaft 110 to rotate in the opposite direction, so that the released material tape is rewound to the outer periphery of the unreleased material tape. The inner surface of the released material tape can be bonded to the outer surface of the unreleased material tape through the liquid, thereby reducing the risk of the roll material 10 spreading out during the subsequent transportation to the coating device.

[0197] Please continue reading Fig.11 In some embodiments, the spray mechanism 900 includes a nozzle 910 and a tenth driving member 920 connected to the nozzle 910 , and the tenth driving member 920 is used to drive the nozzle 910 to rotate around a rotation axis, and the rotation axis extends along the axial direction of the bearing shaft 110 .

[0198] The nozzle 910 is a component of the spray mechanism 900 for spraying liquid onto the inner surface of the material strip after the coil 10 is released. The tenth driving member 920 is used to connect with the nozzle 910 and drive the nozzle 910 to rotate around the rotation axis. The tenth driving member 920 can have various structures, for example, the tenth driving member 920 can be a driving motor.

[0199] Under the drive of the tenth driving member 920, the angle at which the nozzle 910 sprays the liquid onto the inner surface of the material strip released from the coil 10 changes, so as to spray the liquid onto a specific area of ​​the inner surface of the material strip. In addition, in the process of the nozzle 910 spraying the liquid onto the inner surface of the material strip, the tenth driving member 920 drives the nozzle 910 to reciprocate within a certain angle range, thereby improving the uniformity of the liquid spraying.

[0200] Optionally, the spray mechanism 900 may include a plurality of nozzles 910, which may be arranged at intervals along the axial direction of the bearing shaft 110 and respectively connected to a tenth driving member 920. Driven by the tenth driving member 920, each nozzle 910 may respectively spray liquid onto the inner surface of the material belt, thereby further improving the uniformity of the liquid spraying.

[0201] In the above scheme, the nozzle 910 is driven to rotate around the rotation axis by the tenth driving member 920, and the rotation axis extends axially along the supporting shaft 110, so that the angle of the nozzle 910 when spraying liquid onto the inner surface of the released material strip can be adjusted to improve the liquid spraying effect.

[0202] Please continue reading Fig.11In some embodiments, the roll material processing device also includes a pressure roller mechanism 1000, which is arranged on one side of the load-bearing shaft 110 along the radial direction of the load-bearing shaft 110, and includes a roller 1100 and an eleventh driving member 1200 connected to the roller 1100, and the eleventh driving member 1200 is used to drive the roller 1100 to move in a direction close to or away from the load-bearing shaft 110, and the roller 1100 is used to press the roll material 10.

[0203] The pressure roller mechanism 1000 is a component used to press the roll material 10 during the processing of the roll material 10. The pressure roller mechanism 1000 can be set on one side of the load-bearing shaft 110 along any radial direction of the load-bearing shaft 110. For example, the pressure roller mechanism 1000 can be set on the machine base 500, and it can be located on one side of the peeling mechanism 300 along the second direction Y.

[0204] The pressing roller mechanism 1000 includes a roller 1100 and an eleventh driving member 1200. The roller 1100 is a component of the pressing roller mechanism 1000 that is used for directly contacting the roll material 10 to press the roll material 10. The axial direction of the roller 1100 is parallel to the axial direction of the bearing shaft 110. It can move toward the direction close to the bearing shaft 110 under the drive of the eleventh driving member 1200 to press the roll material 10 and reduce the risk of the roll material 10 spreading out after the adhesive tape is peeled off.

[0205] It can be understood that the roller 1100 is cylindrical in shape. Therefore, when the roller 1100 is pressed against the coil 10 , there is rolling friction between the roller 1100 and the coil 10 , which can reduce the damage to the coil 10 .

[0206] The eleventh driving member 1200 is a member for driving the pressure roller to move in a direction close to or away from the bearing shaft 110. The eleventh driving member 1200 can be arranged on at least one side of the roller 1100 along the axial direction of the roller 1100 to drive the roller 1100 to move. The structure of the eleventh driving member 1200 can be various, for example, the eleventh driving member 1200 can be a linear driving member such as a cylinder or a hydraulic cylinder.

[0207] In the above scheme, the pressing roller mechanism 1000 is arranged on one side of the load-bearing shaft 110 along the radial direction of the load-bearing shaft 110. The pressing roller mechanism 1000 includes a roller 1100 and an eleventh driving member 1200. During the processing of the coil 10, the roller 1100 is driven by the eleventh driving member 1200 to move toward the direction close to the load-bearing shaft 110, so that the roller 1100 presses the surface of the coil 10, thereby reducing the risk of the coil 10 spreading during the processing.

[0208] Second, see Fig.12 The present application also provides a coil material processing method, including: S1. Place the coil 10 on the bearing shaft 110 .

[0209] S2. Detect the position of the adhesive tape attached to the roll material 10 in the initial state by the detection mechanism 200.

[0210] S3. Calculate the time required for the bearing shaft 110 to drive the adhesive tape to rotate to a preset position according to the position of the adhesive tape in the initial state detected by the detection mechanism 200, the rotation speed of the bearing shaft 110 and the outer diameter of the coil 10.

[0211] S4, the support shaft 110 rotates at a corresponding speed for a corresponding time to drive the adhesive tape to a preset position.

[0212] S5. Peeling the adhesive tape at the preset position from the roll material 10 through the peeling mechanism 300.

[0213] In the above scheme, the coil 10 is first loaded and set on the supporting shaft 110. Then, the position of the adhesive tape on the coil 10 in the initial state is detected by the detection mechanism 200. Based on the position in the initial state, the rotation speed of the supporting shaft 110, the outer diameter of the coil 10 and other parameters, the time required for the supporting shaft 110 to drive the adhesive tape to rotate to a preset position at a corresponding rotation speed is calculated. After the supporting shaft 110 rotates for a corresponding time, the supporting shaft 110 is controlled to stop rotating. Then, the adhesive tape at the preset position is peeled off from the coil 10 by the peeling mechanism 300. On the one hand, the adhesive tape can be automatically removed and the pretreatment efficiency of the coil 10 can be improved. On the other hand, the above method can be used to peel off the adhesive tape on the coil 10, which can effectively improve the peeling accuracy of the adhesive tape and improve the pretreatment quality of the coil 10, thereby improving the preparation yield and quality of the electrode in the subsequent coating process, and improving the production efficiency and performance of battery cells and battery devices.

[0214] See also Fig.13 In some embodiments, the step of detecting the initial position of the adhesive tape attached to the web 10 by the detection mechanism 200 includes: S21, detecting the position of the adhesive tape along the axial direction and the second direction Y of the bearing shaft 110 in the initial state by the first detection member 210; The step of peeling the adhesive tape at the preset position from the roll material 10 by the peeling mechanism 300 includes: S51, driving the stripping member 320 to move along the axial direction of the bearing shaft 110 by the second driving member 310, and identifying the adhesive tape by the second detecting member during the movement of the stripping member 320; S52: After the second detection element recognizes the adhesive tape, the peeling element 320 stops moving and peels off the adhesive tape.

[0215] In the above scheme, after the first detection member 210 detects the position of the adhesive tape along the axial direction and the second direction Y of the bearing shaft 110 in the initial state, the time required for the bearing shaft 110 to drive the adhesive tape to rotate to the preset position at a corresponding speed is calculated based on parameters such as the position, and after the bearing shaft 110 rotates for a corresponding time, the bearing shaft 110 is controlled to stop rotating. Subsequently, the second driving member 310 drives the stripping member 320 to move along the axial direction of the bearing shaft 110, so that the stripping member 320 has the ability to strip the adhesive tape at different positions of the roll 10, thereby improving the flexibility and practicality of the stripping mechanism 300 and the stripping efficiency of the adhesive tape. Moreover, during the movement, the adhesive tape on the roll material 10 is identified by the second detection member arranged on the stripping member 320. After the second detection member identifies the adhesive tape, the second driving member 310 is controlled to stop the stripping member 320. At this time, the positions of the stripping member 320 and the adhesive tape correspond. The stripping member 320 can accurately strip the adhesive tape, which can improve the position accuracy of the stripping member 320 and the adhesive tape in the axial direction of the supporting shaft 110, and further improve the success rate of stripping the adhesive tape by the stripping member 320 and the pre-processing quality of the roll material 10.

[0216] It should be noted that the components such as the bearing shaft 110 and the detection mechanism 200 mentioned in this embodiment have been described in detail in the coil processing device provided in the first aspect of the embodiment of the present application, and thus will not be repeated here.

[0217] In a third aspect, an embodiment of the present application further provides a coating system, comprising any of the above coil material processing devices and a coating die, wherein the coating die is used to coat slurry on the material strip released from the coil material 10 .

[0218] It should be noted that the coating system may include a coating device, and the coating die head may be a component in the coating device for coating the slurry on the surface of the material strip released by the coil 10. The coating device may also include a support shaft, and the coil 10 is arranged on the support shaft. During the rotation of the support shaft, the coil 10 can release the material strip driven by the support shaft, so that the coating die head can coat the slurry on the released material strip.

[0219] In some embodiments, the present application provides a web processing device, a web processing method and a coating system. The web processing device includes a bearing mechanism 100, a detection mechanism 200 and a stripping mechanism 300.
