Description

Technical Field

[0001] This utility model relates to the field of marking device technology, and in particular to an electrode quality marking device. Background Technology

[0002] In related technologies, during the lithium battery production process, there is a slitting process where wide electrode sheets are divided into multiple electrode sheets. To prevent substandard electrode sheets from flowing to subsequent processes, an electrode sheet quality marking device is used to mark the substandard electrode sheets. The electrode sheet quality marking device includes a marking machine, which marks the substandard electrode sheets to facilitate identification in the next process. The marking machine needs to replace the labels regularly, which increases the workload of the workers. In addition, the operation is difficult for the workers, and the electrode sheet quality marking device needs to be stopped when the labels are replaced, which affects the working efficiency of the electrode sheet quality marking device.

[0003] Furthermore, existing electrode quality marking devices are equipped with multiple marking machines, each used to mark the corresponding electrode, resulting in a large length of the electrode quality marking device and increasing the difficulty of its arrangement. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide an electrode quality marking device that eliminates the need for label replacement, reducing the workload and operational difficulty for workers, and thus improving the working efficiency of the electrode quality marking device.

[0005] An electrode quality marking device according to the present invention includes:

[0006] The roller assembly and the detection mechanism are arranged along a first direction. The roller assembly is used to support the electrode during the electrode belt feeding process, and the detection mechanism is used to detect the quality information of the electrode to determine whether the quality of the electrode is qualified.

[0007] The embossing mechanism, along the first direction, is located on the same side of the roller assembly as the detection mechanism, and the embossing mechanism is located downstream of the detection mechanism. The embossing mechanism is configured to press against the electrode sheet to deform the electrode sheet when the quality of the electrode sheet is determined to be unqualified.

[0008] According to the present invention, the electrode quality marking device uses an embossing mechanism to mark unqualified electrodes. Compared with the prior art, it eliminates the need to replace labels, reducing the workload and operational difficulty for workers, and improving the working efficiency of the electrode quality marking device.

[0009] In some examples of this utility model, the embossing mechanism includes: a pressure shaft and a pressure roller. The pressure shaft extends along a second direction, and the pressure roller is sleeved on the pressure shaft and can rotate relative to the pressure shaft in the direction of the electrode's conveyor belt about the second direction. The pressure shaft drives the pressure roller to move synchronously relative to the roller assembly along a first direction. The pressure roller is used to press against the electrode to deform the electrode. The first direction and the second direction are perpendicular.

[0010] In some examples of this invention, the pressure roller is configured to rotate under the influence of the electrode sheet while pressing against it and during the electrode sheet's conveyor belt movement.

[0011] In some examples of this utility model, the embossing mechanism further includes: a first driving structure, which works in conjunction with the pressure roller, and the first driving structure is configured to drive the pressure roller to rotate.

[0012] In some examples of this utility model, the first drive structure is also configured to cooperate with the pressure roller limiter to restrict the rotation of the pressure roller.

[0013] In some examples of this utility model, the outer peripheral wall of the pressure roller is formed with an embossed portion, which is used to press against the electrode sheet. The embossed portion extends along the circumference of the pressure roller and has a first end and a second end along the circumference of the pressure roller. The first end and the second end are spaced apart to form a clearance space between the first end and the second end. The first end is provided with a first magnetic attractor. The first driving structure is located on the downstream side of the pressure roller. The first driving structure has a driving rod that can move toward or away from the pressure roller. The free end of the driving rod has a second magnetic attractor. During the rotation of the pressure roller, the first end can be opposite to the free end of the driving rod so that the first magnetic attractor and the second magnetic attractor abut against each other.

[0014] In some examples of this utility model, a counterweight is fixed on at least one side of the pressure roller along the axial direction of the pressure shaft, and the counterweight and the pressure shaft are arranged radially along the pressure shaft. The counterweight is used to drive the pressure roller to rotate.

[0015] In some examples of this utility model, there are multiple pressure rollers and multiple first drive structures. The multiple pressure rollers are all sleeved on the pressure shaft and spaced apart in sequence along the second direction. The multiple pressure rollers and multiple first drive structures correspond one-to-one.

[0016] In some examples of this utility model, the electrode quality marking device further includes: a second driving structure, which is connected to the pressure shaft via a transmission, and the second driving structure is used to drive the pressure shaft to move along a first direction.

[0017] In some examples of this utility model, the electrode quality marking device further includes a limiting structure for restricting the movement of the pressure shaft toward the roller assembly along a first direction.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] Electrode 200; Thickness gauge 300. Detailed Implementation

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The following is for reference. Figures 1-7 The electrode quality marking device 100 according to an embodiment of the present utility model is used to detect whether the quality of the electrode 200 is qualified, and the electrode quality marking device 100 can emboss the electrode 200 that is not qualified, thereby achieving the effect of marking the electrode 200 that is not qualified.

[0039] like Figures 1-7 As shown, the electrode quality marking device 100 includes: a roller assembly 10 and a detection mechanism 20, which are arranged along a first direction. The roller assembly 10 is used to support the electrode 200 during the belt conveying process, and the detection mechanism 20 is used to detect the quality information of the electrode 200 to determine whether the quality of the electrode 200 is qualified; and an embossing mechanism 30, which is located on the same side of the roller assembly 10 along the first direction, and the embossing mechanism 30 is located downstream of the detection mechanism 20. The embossing mechanism 30 is configured to press against the electrode 200 to deform the electrode 200 when the quality of the electrode 200 is determined to be unqualified.

[0040] The electrode quality marking device 100 includes: an embossing mechanism 30, a roller assembly 10, and a detection mechanism 20. For example... Figure 1 As shown, the first direction can be Figure 1 In the Z direction, the first direction can be the height direction of the electrode quality marking device 100. This application uses the height direction of the electrode quality marking device 100 as an example for explanation. The roller assembly 10 and the detection mechanism 20 are arranged along the first direction, with the roller assembly 10 located below the detection mechanism 20. Figure 1 As shown, the roller assembly 10 may include multiple rollers 11, which are arranged sequentially along the belt-carrying direction of the electrode 200. Each roller 11 supports the electrode 200, and the rollers 11 are rotatable about a second direction. The first and second directions are perpendicular. Figure 1 As shown, the second direction is Figure 1 In the Y direction, multiple rollers 11 are used to support the electrode 200 during the belt travel process.

[0041] The inspection mechanism 20 is used to inspect the quality information of the electrode 200, which may include dimensional information and appearance defect information. For example, the inspection mechanism 20 can be a CCD camera, video recorder, etc. During the electrode 200's transport process, the inspection mechanism 20 inspects the quality information of the electrode 200 and determines whether the electrode 200's quality is acceptable based on the inspected quality information. As an example, the inspection mechanism 20 determines whether the electrode 200's quality is acceptable based on its own inspected quality information. As an example, the inspection mechanism 20 is communicatively connected to a controller, and transmits the inspected quality information to the controller, which then determines whether the electrode 200's quality is acceptable based on the inspected quality information.

[0042] Along the first direction, the embossing mechanism 30 and the detection mechanism 20 are located on the same side of the roller assembly 10. In other words, the embossing mechanism 30 and the detection mechanism 20 are located on the upper side of the roller assembly 10. Along the belt-running direction of the electrode 200, the embossing mechanism 30 is located on the downstream side of the detection mechanism 20. In the case of unqualified electrode 200, the embossing mechanism 30 presses against the unqualified electrode 200 to deform the electrode 200, thereby marking the unqualified electrode 200. For example, the embossing mechanism 30 presses against the unqualified electrode 200 to deform a part of the structure of the electrode 200 in a direction away from the embossing mechanism 30.

[0043] Specifically, during the production process, the electrode sheet 200 moves along the conveyor belt direction. Each roller 11 supports the electrode sheet 200, and the electrode sheet 200 drives the multiple rollers 11 to rotate. Simultaneously, the detection mechanism 20 detects the quality information of the electrode sheet 200. When there are no defective products (i.e., when the electrode sheet 200 is of acceptable quality), the embossing mechanism 30 does not press against the electrode sheet 200. When there are defective products (i.e., when the electrode sheet 200 is of unacceptable quality), the embossing mechanism 30 presses against the electrode sheet 200, causing the electrode sheet 200 to deform. The unacceptable electrode sheet 200 is marked. After marking the unacceptable electrode sheet 200, the embossing mechanism 30 separates from the electrode sheet 200. The surface of the pressed electrode sheet 200 is uneven, and subsequent processes can use a thickness gauge 300 to identify, inspect, and reject defective products.

[0044] Therefore, by setting up the embossing mechanism 30, the defective electrode 200 can be marked. Compared with the existing technology, there is no need to replace the label, which reduces the workload of the staff and the difficulty of operation, and helps to improve the working efficiency of the electrode quality marking device 100.

[0045] In some examples of this utility model, such as Figure 1 and Figure 2As shown, the embossing mechanism 30 includes a pressure shaft 31 and a pressure roller 32. The pressure shaft 31 extends along a second direction, and the pressure roller 32 is sleeved on the pressure shaft 31 and can rotate relative to the pressure shaft 31 in the direction of the electrode 200 about the second direction. The pressure shaft 31 drives the pressure roller 32 to move synchronously relative to the roller assembly 10 along a first direction. The pressure roller 32 is used to press against the electrode 200 to deform the electrode 200. The first direction and the second direction are perpendicular.

[0046] The embossing mechanism 30 may include a pressure shaft 31 and a pressure roller 32. The pressure shaft 31 extends along a second direction, and the pressure roller 32 is fitted with a through hole 327. The pressure shaft 31 passes through the through hole 327, thereby fitting the pressure roller 32 onto the pressure shaft 31. A bearing 60 may be provided between the pressure shaft 31 and the pressure roller 32, allowing the pressure roller 32 to rotate relative to the pressure shaft 31 in the second direction toward the belt-carrying direction of the electrode sheet 200. The pressure shaft 31 can drive the pressure roller 32 to move synchronously along a first direction, thereby adjusting the gap between the embossing mechanism 30 and the corresponding guide roller 11, and also adjusting the embossing mechanism 30 to a suitable position along the first direction. For example, the pressure shaft 31 drives the pressure roller 32 to move toward the electrode sheet 200 along the first direction, bringing the pressure roller 32 closer to the electrode sheet 200. After the pressure roller 32 moves to a suitable position, the pressure shaft 31 stops moving. When a defective electrode (i.e., when the electrode 200 is substandard) is present, the pressure roller 32 presses against the electrode 200. Then, the pressure roller 32 rotates relative to the pressure shaft 31 in the direction of the electrode 200's conveyor belt, causing the electrode 200 to deform. This marks the substandard electrode 200. After marking, the pressure roller 32 separates from the electrode 200, waiting for the next substandard electrode 200 to appear before marking it again. By setting the pressure shaft 31 and the pressure roller 32, the effect of embossing and marking substandard electrode 200 can be achieved. This simplifies the structure of the embossing mechanism 30. Furthermore, if the pressure roller 32 is damaged, it can be replaced independently without replacing the entire embossing mechanism 30, thus reducing the maintenance cost of the electrode quality marking device 100.

[0047] For example, the outer peripheral wall of the pressure roller 32 is formed with an embossing portion 321, the embossing portion 321 having a plurality of embossing bosses 328, the plurality of embossing bosses 328 being arranged in sequence at intervals along the circumference of the pressure roller 32. When the embossing mechanism 30 presses against the electrode 200, the embossing bosses 328 press against the electrode 200 to cause the electrode 200 to protrude and deform in a direction away from the embossing mechanism 30.

[0048] In some examples of this utility model, such as Figure 3 As shown, the pressure roller 32 is configured to be driven to rotate by the electrode 200 when pressing against the electrode 200 and during the electrode 200's conveyor belt movement.

[0049] In cases where the electrode 200 is determined to be substandard, the pressure roller 32 moves to the position where the embossing protrusions 328 abut against the electrode 200. As the electrode 200 travels, it drives the pressure roller 32 to rotate, causing the multiple embossing protrusions 328 to emboss the electrode 200. By configuring the pressure roller 32 to be driven to rotate by the electrode 200 while pressing against it and during its travel, the drive structure for embossing the electrode 200 can be eliminated. This simplifies the structure of the electrode quality marking device 100 and reduces its manufacturing cost.

[0050] In some examples of this utility model, such as Figure 1 and Figure 2 As shown, the embossing mechanism 30 also includes a first drive structure 33, which works in conjunction with the pressure roller 32. The first drive structure 33 is configured to drive the pressure roller 32 to rotate.

[0051] The embossing mechanism 30 may further include a first drive structure 33. As an example, the first drive structure 33 may be a drive motor, the output shaft of which may be connected to the pressure roller 32. When the quality of the electrode 200 is determined to be substandard, the pressure roller 32 abuts against the electrode 200, and the drive motor operates. The drive motor can drive the pressure roller 32 to rotate relative to the pressure shaft 31 in the direction of the electrode 200's conveyor belt, thereby causing the electrode 200 to bulge and deform in the direction away from the embossing mechanism 30, achieving an uneven surface effect on the electrode 200.

[0052] In some examples of this utility model, such as Figure 1 and Figure 2 As shown, the first drive structure 33 is also configured to cooperate with the pressure roller 32 to limit the rotation of the pressure roller 32.

[0053] When the electrode 200 is of acceptable quality, the pressure roller 32 and the electrode 200 are separated. The first drive structure 33 is matched with the pressure roller 32 in a limiting manner. The first drive structure 33 can limit the rotation of the pressure roller 32, thereby achieving the effect of limiting the rotation of the pressure roller 32.

[0054] In some examples of this utility model, such as Figures 1-5As shown, the outer peripheral wall of the pressure roller 32 is formed with an embossed portion 321. The embossed portion 321 is used to press against the electrode sheet 200. The embossed portion 321 extends along the circumference of the pressure roller 32 and has a first end 322 and a second end 323 along the circumference of the pressure roller 32. The first end 322 and the second end 323 are spaced apart to form a clearance space 324 between the first end 322 and the second end 323. The first end 322 is provided with a first magnetic attractor 325. The first drive structure 33 is located on the downstream side of the pressure roller 32. The first drive structure 33 has a drive rod 331. The drive rod 331 can move toward or away from the pressure roller 32. The free end of the drive rod 331 has a second magnetic attractor 332. During the rotation of the pressure roller 32, the first end 322 can be opposite to the free end of the drive rod 331 so that the first magnetic attractor 325 and the second magnetic attractor 332 abut against each other.

[0055] The outer peripheral wall of the pressure roller 32 has an embossed portion 321, which has multiple embossed protrusions 328 for pressing the electrode sheet 200. The embossed portion 321 extends circumferentially along the pressure roller 32 and is a non-closed ring structure, which can also be understood as an arc-shaped structure. The multiple embossed protrusions 328 are arranged at intervals along the circumferential direction of the pressure roller 32. The embossed portion 321 has a first end 322 and a second end 323 along the circumferential direction of the pressure roller 32. The first end 322 and the second end 323 are spaced apart along the circumferential direction of the pressure roller 32, thereby forming a clearance space 324 between the first end 322 and the second end 323.

[0056] The first end 322 is provided with a first magnetic attractor 325. Along the belt-carrying direction of the pole piece 200, the first driving structure 33 is located downstream of the pressure roller 32. Exemplarily, the first driving structure 33 is a driving cylinder, which has a driving rod 331. The driving rod 331 can be a first telescopic rod, or the driving rod 331 can be a movable rod body, so that the driving rod 331 can move toward or away from the pressure roller 32. This application uses the driving rod 331 as a first telescopic rod as an example for description. The free end of the first telescopic rod has a second magnetic attractor 332. The first magnetic attractor 325 and the second magnetic attractor 332 attract each other. Both the first magnetic attractor 325 and the second magnetic attractor 332 can be magnets. During the rotation of the pressure roller 32, the first end 322 can be opposite to the free end of the driving rod 331, so that the first magnetic attractor 325 and the second magnetic attractor 332 abut against each other.

[0057] Specifically, such as Figure 2As shown, during the production process, if the electrode 200 is of acceptable quality, the drive rod 331 extends into the clearance space 324, causing the first magnetic attractor 325 and the second magnetic attractor 332 to contact, preventing the pressure roller 32 from rotating in the direction of the electrode 200's conveyor belt. When an electrode 200 is of unacceptable quality, the controller controls the first drive structure 33 to operate, causing the drive rod 331 of the first drive structure 33 to move away from the pressure roller 32. During the movement of the drive rod 331, the pressure roller 32 is driven to rotate by the mutual attraction of the first magnetic attractor 325 and the second magnetic attractor 332. The pressure roller 32 rotates to... Figure 3 After reaching the indicated position, the first embossed protrusion 328 abuts against the electrode 200. Then, the pressure roller 32 rotates under the drive of the electrode 200 until all the embossed protrusions 328 have completed embossing the electrode 200. After all the embossed protrusions 328 have embossed the electrode 200, the pressure roller 32 continues to rotate. When the pressure roller 32 rotates to the point where the clearance space 324 is opposite to the electrode 200, the drive rod 331 moves toward the pressure roller 32 to extend into the clearance space 324. At this time, the pressure roller 32 continues to rotate until the first magnetic suction member 325 and the second magnetic suction member 332 contact and block the pressure roller 32 from rotating (e.g., Figure 3 (As shown).

[0058] By setting a drive rod 331, after the drive rod 331 is limited to the first end 322, the drive rod 331 can restrict the rotation of the pressure roller 32. Furthermore, by setting a first magnetic suction member 325 and a second magnetic suction member 332, the pressure roller 32 can be driven to rotate by the magnetic attraction of the first magnetic suction member 325 and the second magnetic suction member 332. At the same time, by setting a clearance space 324, it is convenient for the drive rod 331 and the pressure roller 32 to work together, reducing the manufacturing difficulty of the electrode quality marking device 100.

[0059] In some examples of this utility model, such as Figure 2 and Figure 5 As shown, along the axial direction of the pressure shaft 31, at least one side of the pressure roller 32 is fixed with a counterweight 326. The counterweight 326 and the pressure shaft 31 are arranged radially along the pressure shaft 31. The counterweight 326 is used to drive the pressure roller 32 to rotate.

[0060] Along the axial direction of the pressure shaft 31, i.e., along the second direction, at least one side of the pressure roller 32 is fixed with a counterweight 326. That is, a counterweight 326 may be fixed to one side of the pressure roller 32, or both sides of the pressure roller 32 may be fixed with a counterweight 326. This application uses the example of one counterweight 326 fixed to one side of the pressure roller 32 for illustration. The counterweight 326 can be welded to the pressure roller 32, fixed to the pressure roller 32 with bolts, or snap-fitted to the pressure roller 32. The counterweight 326 and the pressure shaft 31 are arranged radially along the pressure shaft 31, with the counterweight 326 located outside the through hole 327. By setting the counterweight 326, the pressure roller 32 can have an eccentric force, allowing it to continue rotating under its own eccentric gravity when it reaches a certain position.

[0061] Specifically, such as Figure 2 As shown, during the production process, if the electrode 200 is of qualified quality, the drive rod 331 extends into the clearance space 324, causing the first magnetic suction component 325 and the second magnetic suction component 332 to come into contact, and the blocking pressure roller 32 rotates in the direction of the electrode 200 under its own eccentric gravity.

[0062] When an electrode 200 fails to meet quality standards, the controller activates the first drive structure 33, causing the drive rod 331 of the first drive structure 33 to retract and move away from the pressure roller 32. During the movement of the drive rod 331, the pressure roller 32 is driven to rotate under the combined forces of its own eccentric gravity and magnetic attraction (the mutual attraction force between the first magnetic attractor 325 and the second magnetic attractor 332). The pressure roller 32 rotates to... Figure 3 After the indicated position, the electrode 200 is pressed between a roller 11 and the first embossing boss 328. Then, the pressure roller 32 rotates under the drive of the electrode 200 until all the embossing bosses 328 have completed embossing the electrode 200. After all the embossing bosses 328 have embossed the electrode 200, the controller controls the drive rod 331 of the first drive structure 33 to extend after a delay. The pressure roller 32 continues to rotate under its own inertial force. When the pressure roller 32 rotates to the point where the clearance space 324 is opposite to the electrode 200, the drive rod 331 extends towards the pressure roller 32 to enter the clearance space 324. At this time, the pressure roller 32 continues to rotate until the first magnetic suction member 325 and the second magnetic suction member 332 contact and block the pressure roller 32 from rotating (e.g., Figure 3 (As shown).

[0063] In some examples of this utility model, such as Figure 1 As shown, there are multiple pressure rollers 32 and multiple first drive structures 33. Multiple pressure rollers 32 are all sleeved on the pressure shaft 31 and spaced apart in sequence along the second direction. Multiple pressure rollers 32 and multiple first drive structures 33 correspond one-to-one.

[0064] Multiple pressure rollers 32 and first drive structures 33 are provided. The number of pressure rollers 32 and first drive structures 33 can be two, three, four, five, six, etc., and can be reasonably selected according to actual conditions. Multiple pressure rollers 32 are fitted onto the pressure shaft 31, and the multiple pressure rollers 32 are arranged alternately along the second direction. Multiple first drive structures 33 are also arranged alternately along the second direction, with each first drive structure 33 located downstream of its corresponding pressure roller 32. Figure 1 As shown, exemplarily, the roller assembly 10 can simultaneously support multiple electrode sheets 200. The multiple electrode sheets 200 and multiple pressure rollers 32 are arranged one-to-one along a first direction, with the pressure rollers 32 pressing against the corresponding electrode sheets 200. By using multiple pressure rollers 32 and multiple first drive structures 33, and arranging the multiple pressure rollers 32 sequentially at intervals along a second direction, the structure of the electrode quality marking device 100 can be made more compact, which helps to reduce the length of the electrode quality marking device 100 and reduces the difficulty of arranging the electrode quality marking device 100.

[0065] In some examples of this utility model, such as Figure 1 As shown, the electrode quality marking device 100 further includes a second drive structure 40, which is connected to the pressure shaft 31 in a transmission manner. The second drive structure 40 is used to drive the pressure shaft 31 to move along a first direction.

[0066] The electrode quality marking device 100 may further include a second drive structure 40, which is connected to the pressure shaft 31. The second drive structure 40 can drive the pressure shaft 31 to reciprocate along a first direction. When the embossing mechanism 30 needs to move towards the electrode 200, the second drive structure 40 drives the pressure shaft 31 to move the pressure roller 32 synchronously towards the electrode 200. When the embossing mechanism 30 needs to move away from the electrode 200, the second drive structure 40 drives the pressure shaft 31 to move the pressure roller 32 synchronously away from the electrode 200. By setting the second drive structure 40, the embossing mechanism 30 can be driven to rise and fall, thereby adjusting the gap between the embossing mechanism 30 and the corresponding roller 11, and also adjusting the embossing mechanism 30 to a suitable height position.

[0067] As an example, the second drive structure 40 can be a clamping cylinder with a telescopic second telescopic rod 41. The second telescopic rod 41 is fixedly connected to the pressure shaft 31 via a connecting block 42. The extension and retraction of the second telescopic rod 41 achieves the lifting effect of the embossing mechanism 30. As another example, the second drive structure 40 includes a drive motor, a lead screw, and a nut. The lead screw extends along a first direction, and the drive motor is connected to the lead screw to drive the lead screw to rotate around the first direction. The nut is sleeved on the lead screw and fixedly connected to the pressure shaft 31. The drive motor drives the lead screw to rotate, so that the nut drives the pressure shaft 31 to move synchronously along the first direction, thereby achieving the lifting effect of the embossing mechanism 30.

[0068] In some examples of this utility model, such as Figure 1 As shown, the electrode quality marking device 100 further includes a limiting structure 50, which limits the movement of the pressure shaft 31 toward the roller assembly 10 along the first direction.

[0069] The electrode quality marking device 100 may further include a limiting structure 50, which may be a limiting plate. Along the first direction, the limiting structure 50 is located below the connecting block 42. During the production process, the second driving structure 40 drives the pressure shaft 31 to move toward the electrode 200 until the limiting structure 50 and the connecting block 42 contact the limiting position. Then, the second driving structure 40 stops driving the pressure shaft 31 to move toward the electrode 200, thereby adjusting the pressure shaft 31 to a suitable position.

[0070] In some examples of this utility model, one of the multiple rollers 11 is a rubber-coated roller. The rubber-coated roller and the embossing mechanism 30 are arranged opposite each other along the first direction. The inner ring of the rubber-coated roller can be hard metal (usually stainless steel), and the outer ring is covered with a ring of rubber or polyurethane. The hardness can be Shore hardness A40-A70.

[0071] It should be noted that, Figures 2-4 The arrow in the image indicates the direction of the electrode 200's travel.
