Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and particularly to a tape embossing device. Background Art

[0002] The embossing technology for battery cell electrodes is a process used to improve electrode performance during battery manufacturing. This technology forms specific concave and convex textures on the surface of the electrode sheet to increase the specific surface area of the electrode material, improve the charge transfer efficiency, enhance the contact between the electrode and the electrolyte, thereby improving the energy density, cycle life, and safety performance of the battery. The embossing process can reduce the phenomenon of wrinkles generated during the winding or lamination of the electrode sheet, optimize the infiltration effect of the electrolyte, reduce the shedding of active materials, and improve the overall performance of the battery.

[0003] In the existing related technologies, generally, the electrode sheet is transmitted downstream by the power provided by the upstream power mechanism. The electrode sheet drives the embossing roller and the supporting roller to rotate through friction between the embossing roller and the supporting roller. When passing between the embossing roller and the supporting roller, the driving mechanism drives the embossing roller to press against the supporting roller, thereby embossing the electrode sheet, and the electrode sheet is transmitted downstream after embossing. However, when the pressing force of the embossing roller against the supporting roller is large, and the embossing roller and the supporting roller do not have power, the friction force that the electrode sheet needs to provide for the embossing roller and the supporting roller increases, which may cause the electrode sheet to break during the embossing process, thereby affecting the embossing effect of the electrode sheet, reducing the embossing efficiency of the electrode sheet, and increasing the embossing cost.

[0037] The embossing technology of battery cell electrodes is a key process in battery production for optimizing electrode performance. By creating a unique concave-convex structure on the electrode surface, this technology increases the surface area of the electrode material, promotes the rapid transmission of charges, and enhances the more effective contact between the electrode and the electrolyte. This not only increases the energy density and cycle stability of the battery, but also improves the uniform distribution of the electrolyte by reducing wrinkles during the winding or stacking process, prevents the peeling of active materials, and thus improves the performance and safety of the battery.

[0038] Please refer to Figure 1 With Figure 2, in battery manufacturing, traditional embossing techniques rely on the frictional force between the embossing roller and the support roller to transmit power and transfer the power from the upstream mechanism to the electrode sheet. When the pressure of the embossing roller on the support roller is relatively large, if the embossing roller and the support roller do not have their own power, the electrode sheet must provide sufficient frictional force to drive the embossing roller and the support roller to rotate. In this case, the electrode sheet may break during the embossing process due to excessive frictional force, which not only affects the quality of embossing but also reduces production efficiency and increases costs.

[0039] Based on this, the embodiments of the present application disclose a strip embossing device, which can prevent the electrode sheet from breaking and being damaged during the embossing process due to the large frictional force required by the embossing roller and the support roller when the pressing force of the embossing roller on the support roller is relatively large, thereby improving the embossing effect of the electrode sheet, reducing the generation of waste, and improving the embossing efficiency of the electrode sheet.

[0040] The technical solution of the present application will be further described below in conjunction with the embodiments and the drawings.

[0041] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a strip embossing device 100 in the present application;

[0042] The embodiments of the present application disclose a strip embossing device 100, including:

[0043] A mounting base 1;

[0044] A support roller 2, which is rotatably arranged on the mounting base 1;

[0045] An embossing roller 3, which is slidably arranged on the mounting base 1 along the first direction F1, and the embossing roller 3 is arranged parallel to the support roller 2;

[0046] A first driving component 4, which is connected to the embossing roller 3 to drive the embossing roller 3 to approach or move away from the support roller 2 along the first direction F1 to clamp or release the strip 10;

[0047] A second driving component 5, which is in transmission connection with the support roller 2 to drive the support roller 2 to rotate when the embossing roller 3 and the support roller 2 clamp the strip 10, so that the support roller 2 applies a conveying force to the strip 10; or the second driving component 5 is connected to the embossing roller 3 to drive the embossing roller 3 to rotate when the embossing roller 3 and the support roller 2 clamp the strip 10, so that the embossing roller 3 applies a conveying force to the strip 10.

[0048] Specifically, when the strip embossing device 100 operates, the support roller 2 located on the mounting base 1 is driven by the second drive assembly 5 to rotate around the axis of the support roller 2. The first drive assembly 4 drives the embossing roller 3 located on the mounting base 1 to approach the support roller 2 to emboss the strip 10. The strip 10 passes between the support roller 2 and the embossing roller 3. The support roller 2 provides a conveying force for the strip 10 to drive the strip 10 to be transmitted downstream. The strip 10 drives the embossing roller 3 to rotate through friction, or the embossing roller 3 located on the mounting base 1 is driven by the second drive assembly 5 to rotate around the axis of the embossing roller 3. The first drive assembly 4 drives the embossing roller 3 to approach the support roller 2 to emboss the strip 10. The strip 10 passes between the support roller 2 and the embossing roller 3. The embossing roller 3 drives the strip 10 to be transmitted downstream. The strip 10 drives the support roller 2 to rotate through friction.

[0049] Among them, compared with the support roller 2 and the embossing roller 3 having no power and driving the support roller 2 and the embossing roller 3 to rotate through the friction of the strip 10, providing rotational power for the support roller 2 or the embossing roller 3 can enable the support roller 2 or the embossing roller 3 to no longer rely entirely on the friction provided by the strip 10 to rotate, which can reduce the load of the strip 10, reduce the risk of wear and breakage of the strip 10, ensure the embossing effect of the strip 10, and reduce the generation of waste; secondly, the independent drive device can more precisely control the rotation speed and pressure of the support roller 2 or the embossing roller 3, thereby improving the accuracy and consistency of embossing.

[0050] It should be noted that during the embossing process of the strip 10, preferably, the second drive assembly 5 drives the support roller 2 to rotate. First of all, due to the elastic characteristics of its material, the support roller 2 can distribute the pressure more evenly to the entire surface of the strip 10, ensuring the consistency and clarity of the embossing pattern. In contrast, the hardness of the embossing roller 3 is usually higher, and it may be difficult to achieve the same uniform pressure distribution by direct drive; secondly, during the process of the embossing bumps on the embossing roller 3 directly contacting the strip 10 and applying pressure, the wear will be faster than that of the support roller 2. If the embossing roller 3 is directly driven by a motor, its wear will directly affect the embossing quality, and the cost and difficulty of replacing or repairing the embossing roller 3 are usually higher. The support roller 2 can act as a buffer layer to absorb part of the wear and extend the service life of the embossing roller 3; moreover, the rotation of the support roller 2 can more easily match the speed of the production line to ensure the stability and consistency of the strip 10 during the conveying process. The second drive assembly 5 drives the support roller 2 to rotate, and the synchronization with the embossing roller 3 can be achieved by precisely controlling its rotation speed to ensure the continuity and quality of the embossing process; in addition, the elastic characteristics of the support roller 2 enable it to have better adaptability when facing strips 10 with different thicknesses or hardnesses. The motor drives the support roller 2 to rotate, and the pressure and speed can be adjusted according to the characteristics of the strip 10 to improve the flexibility of the embossing effect.

[0051] In some embodiments, please refer to Figures 3 to 5, the supporting roller 2 is rotatably arranged on the mounting base 1 through the rotating shaft 61. The supporting roller 2 is provided with a one-way bearing 62. The outer ring of the one-way bearing 62 is relatively fixed to the supporting roller 2, and the inner ring of the one-way bearing 62 is relatively fixed to the rotating shaft 61. The second driving assembly 5 can drive the rotating shaft 61 to rotate in the first rotation direction. When the rotating shaft 61 rotates in the first rotation direction, the rotating shaft 61 drives the supporting roller 2 to rotate through the one-way bearing 62. When the rotating shaft 61 stops rotating, the strip 10 drives the supporting roller 2 to rotate relative to the rotating shaft 61 through the one-way bearing 62.

[0052] Specifically, the one-way bearing 62 is a special bearing that allows the shaft to rotate freely in one direction while generating a large resistance in the opposite direction, thereby achieving a locking function. This bearing usually includes rollers, needle rollers or balls, and the shape design of its rolling seat enables the rolling elements to roll only in one direction. The working principle of the one-way bearing 62 is based on the cooperation of internal rolling elements and wedge-shaped grooves. Through this structure, the movement of the rolling elements is restricted in one direction, while in the other direction, resistance is generated through a wedging effect. The outer ring of the one-way bearing 62 is relatively fixed to the supporting roller 2, and the inner ring is relatively fixed to the rotating shaft 61. When the second driving assembly 5 works, by utilizing the characteristic that the one-way bearing 62 generates a large resistance in one direction, the second driving assembly 5 can drive the rotating shaft 61 to rotate in the first rotation direction. The rotating shaft 61 drives the supporting roller 2 to rotate in the first rotation direction through the one-way bearing 62, thereby enabling the supporting roller 2 to provide a conveying force for the strip 10. When the second driving assembly 5 does not work, the rotating shaft 61 loses the driving force and does not rotate, and the supporting roller 2 loses the driving force from the rotating shaft 61. The strip 10 provides the driving force for the rotation of the supporting roller 2 through friction. And due to the characteristic of the one-way bearing 62, when the rotating shaft 61 does not rotate, the supporting roller 2 continues to rotate in the first rotation direction. It can be regarded that the rotation direction of the inner ring and the outer ring of the one-way bearing 62 is opposite to the rotation direction when the second driving assembly 5 works. Therefore, the strip 10 can drive the supporting roller 2 to rotate in the first rotation direction relative to the stationary rotating shaft 61.

[0053] Among them, first, when the second drive assembly 5 is working, the one-way bearing 62 allows the rotating shaft 61 (inner ring) and the support roller 2 (outer ring) to rotate synchronously in the first rotation direction. This synchronous rotation ensures the effective transmission of power, allowing the material strip 10 to be conveyed smoothly and powerfully. The one-way bearing 62 reduces unnecessary reverse friction in this process, improves energy conversion efficiency, reduces energy consumption, and reduces wear and tear, thereby extending the life of the equipment. Second, when the second drive assembly 5 stops working, the characteristics of the one-way bearing 62 allow the support roller 2 (outer ring) to continue rotating in the first rotation direction. Even if the rotating shaft 61 (inner ring) is stationary, the material strip 10 can continue to move through its own friction without the need for additional power. This free rotation mode reduces energy consumption during starting and stopping, while providing continuous fluidity during the conveying process of the material strip 10, enhancing the flexibility and response speed of the system, and preventing the device from stopping and causing excessive losses.

[0054] In some embodiments, see Figure 3 The second drive assembly 5 includes a second drive motor 51, which is arranged on the mounting base 1. The second drive motor 51 includes a motor shaft, which is connected to the rotating shaft 61 to drive the rotating shaft 61 to rotate. The strip embossing device 100 also includes a first support plate 63 and a second support plate 64. The first support plate 63 and the second support plate 64 are arranged on the mounting base 1 at intervals along the axial direction of the motor shaft. The first support plate 63 and the second support plate 64 have a connecting surface B perpendicular to the axis of the motor shaft. A reference line 101 is provided on the mounting base 1, and the reference line 101 is arranged along the axial direction of the motor shaft. A scale line 631 is provided on the connecting surface B. The scale line 631 is aligned with the reference line 101 so that the first support plate 63 and the second support plate 64 can be arranged along the axial direction of the motor shaft, and the rotating shaft 61 coincides with the axis of the motor shaft.

[0055] Specifically, the second driving component 5 includes a second driving motor 51. The motor shaft of the second driving motor 51 is connected to the rotating shaft 61 through a coupling to drive the rotating shaft 61 to rotate. The axial directions of the motor shaft and the rotating shaft 61 need to ensure coaxiality to ensure the smoothness during rotation, reduce unnecessary friction, and the effect of embossing the strip 10. Both ends of the rotating shaft 61 are arranged on the first support plate 63 and the second support plate 64. The first support plate 63 and the second support plate 64 are arranged at intervals along the axial direction of the motor shaft on the mounting surface A of the mounting seat 1. The first support plate 63 and the second support plate 64 have a connecting surface B perpendicular to the axis of the motor shaft to ensure that the rotating shaft is parallel to the mounting surface A on the first support plate 63 and the second support plate 64. To determine the relative positions of the first support plate 63 and the second support plate 64 on the mounting surface A, a reference line 101 is provided on the mounting surface A. The reference line 101 is arranged along the axial direction of the motor shaft. A scale line 631 is provided on the connecting surface B. The relative positions of the first support plate 63 and the second support plate 64 are determined by aligning the scale line 631 with the reference line 101. Determining the relative positions of the first support plate 63 and the second support plate 64 further makes the axis of the rotating shaft 61 coincide with the axis of the motor shaft.

[0056] Among them, the precise positioning of the first support plate 63 and the second support plate 64 ensures the coaxiality of the rotating shaft 61 and the motor shaft, thereby reducing energy loss and wear and extending the service life of the equipment. Moreover, the improvement of coaxiality directly reduces the vibration during rotation, can improve the embossing effect and conveying stability of the strip 10, and avoids the possible deviation or damage of the strip 10 caused by vibration. The smooth rotation and precise alignment of the rotating shaft 61 ensure the uniformity and precision of the embossing process, thereby improving the quality and aesthetics of the embossing of the strip 10. And the method of aligning the scale line 631 with the reference line 101 simplifies the installation process of the first support plate 63 and the second support plate 64, reduces the requirements for the skills of operators, and is convenient for subsequent maintenance and adjustment.

[0057] Optionally, to precisely adjust the relative positions of the first support plate 63 and the second support plate 64 on the mounting surface A, please refer to Figure 3 , the strip embossing device 100 further includes an adjusting ruler 68. The adjusting ruler 68 includes an operating end 681 and a contact end 682. The contact end 682 abuts against the first support plate 63. Rotating the operating end 681 can push the contact end 682 to adjust the position of the first support plate 63 relative to the mounting seat 1; or, the contact end 682 abuts against the second support plate 64. Rotating the operating end 681 can push the contact end 682 to adjust the position of the second support plate 64 relative to the mounting seat 1.

[0058] Specifically, when adjusting the relative positions of the first support plate 63 and the second support plate 64 on the mounting surface A, there are inevitable errors during manual adjustment. To reduce the errors, the tape embossing device 100 further includes an adjusting ruler 68. The adjusting ruler 68 includes an operating end 681 and a contact end 682. By rotating the operating end 681, the contact end 682 can move upward or downward. The contact end 682 abuts against the first support plate 63 or the second support plate 64. Rotating the operating end 681 can finely adjust the positions of the first support plate 63 or the second support plate 64 on the mounting surface A through the reference line 101 and the scale line 631.

[0059] Among them, the use of the adjusting ruler 68 allows for fine adjustment of the positions of the first support plate 63 or the second support plate 64, ensuring a higher accuracy in aligning the axis of the rotating shaft 61 with the motor shaft. Through the mechanical transmission of the adjusting ruler 68, the errors caused by manual operation can be reduced, improving the consistency and reliability of the component mounting positions, ensuring coaxiality and rotational smoothness. And the precise axis alignment and component positioning directly promote the stability and efficiency of the embossing device, reducing vibrations and energy losses caused by component misalignment, thereby improving the embossing quality of the tape 10 and the production efficiency.

[0060] In some embodiments, to achieve quick replacement of the support roller, please refer to Figure 4 and Figure 5 , the tape embossing device 100 further includes a first locking member 65, a second locking member 66, and a third locking member 67. The first locking member 65 and the second locking member 66 are arranged at both ends of the support roller 2. The first locking member 65 and the second locking member 66 are respectively sleeved on the rotating shaft 61 to limit the relative positions of the support roller 2 along the axial direction of the rotating shaft 61. The third locking member 67 is arranged on the second support plate 64. The tape embossing device 100 further includes a clamping member 632. The clamping member 632 is arranged on the first support plate 63. Both ends of the rotating shaft 61 pass through the third locking member 67 and the clamping member 632 to rotate on the first support plate 63 and the second support plate 64, so as to limit the relative positions of the rotating shaft 61 along the axial direction of the motor shaft.

[0061] It should be noted that the material of the support roller 2 is a material with good elasticity, softness, wear resistance, chemical resistance, high strength, shear resistance, and viscosity on the surface. Taking the rubber roller as an example of the support roller 2, the rubber roller can provide uniform pressure when the electrode passes through, which can ensure the embossing effect of the tape and the battery performance. The uniform pressure helps to optimize the hole structure of the tape, thereby affecting the electrochemical performance of the battery; the softness of the rubber roller can emboss without damaging the surface of the tape, which helps to maintain the integrity of the tape and improve the overall quality of the battery. The rubber roller has a certain elasticity and can adapt to the minor unevenness of the tape during the embossing process, reducing the damage that may be caused by rigid contact; and by precisely controlling the pressure on the rubber roller, the uneven depth of the indentation caused by the large pressure difference of the embossing roller 3 can be reduced, thereby improving the consistency and performance of the battery; the contact between the rubber roller and the tape can reduce friction, reduce the wear of the tape and the roller, and extend the service life of the equipment, and the material of the support roller 2 is not limited in this application.

[0062] Secondly, the rubber roller will gradually wear during long-term use, which will affect the uniformity and quality of embossing. The worn rubber roller may not be able to provide sufficient pressure to ensure the embossing effect of the tape, thereby affecting the performance of the battery. Moreover, if scratches or deformations appear on the surface of the rubber roller, it will cause wrinkles in the tape when passing through the embossing roller 3, which will affect the flatness of the tape and the subsequent processing quality. Therefore, the support roller 2 needs to be replaced regularly. The two ends of the support roller 2 are respectively fixed on the rotating shaft 61 through the first locking member 65 and the second locking member 66 to limit the relative position of the support roller 2 along the axial direction of the rotating shaft 61. The two ends of the rotating shaft 61 respectively pass through the third locking member 67 and rotate with the clamping member 632 on the first support plate 63 and the second support plate 64 to define the relative position of the rotating shaft 61 along the axial direction of the motor shaft.

[0063] First, when replacing the support roller 2, the first locking member 65 and the second locking member 66 can be unlocked to separate the support roller 2 from the rotating shaft 61. Then, the third locking member 67 and the clamping member 632 are unlocked, so that the rotating shaft 61 is separated from the first support plate 63 and the second support plate 64. Finally, the rotating shaft 61 is separated from the coupling, enabling the rotating shaft 61 to be withdrawn horizontally, thereby replacing the support roller 2. When installing a new support roller 2, first fix the rotating shaft 61 and the support roller 2 with the first locking member 65 and the second locking member 66. Then, fix both ends of the rotating shaft 61 to the first support plate 63 and the second support plate 64 respectively with the third locking member 67 and the clamping member 632. Finally, connect the rotating shaft 61 to the coupling to complete the replacement of the support roller 2. On the one hand, the quick replacement of the support roller can significantly reduce the downtime, avoid the long disassembly and reinstallation process, contribute to improving the production efficiency and the utilization rate of the production line. The quick replacement mechanism reduces the need for complex disassembly tools and also reduces the potential production losses caused by long-term downtime. On the other hand, the standardized replacement steps make the operation simpler, reduce the dependence on professional tools and technicians, and make the maintenance work more efficient. Moreover, the standardized replacement steps reduce the need for employee training, enabling new employees to get started faster. And the standardized replacement process reduces the safety risks during the operation, ensuring the safety of the operators.

[0064] Secondly, the first locking member 65 and the second locking member 66 can accurately define the position of the support roller 2 on the rotating shaft 61, ensuring the stability and consistency during the embossing process. By fixing the positions of the support roller 2 and the rotating shaft 61 with the locking member 65, the axial movement of them during the operation can be effectively prevented, guaranteeing the embossing accuracy. The locking member 65 ensures the firm fixation of the equipment components during the operation, reducing the safety risks caused by the loosening or movement of the components.

[0065] Optionally, refer to Figure 4 and Figure 6 , a scale 611 is provided on the rotating shaft 61. The scale 611 is arranged on the part of the rotating shaft 61 between the first support plate 63 and the second support plate 64. The scale 611 is arranged along the axis direction of the rotating shaft 61. The distance from the side of the first locking member 65 close to the first end 611A to the first end 611A is equal to the distance from the side of the second locking member 66 close to the second end 611B to the second end 611B, so that the position of the support roller 2 on the rotating shaft 61 is the same before and after replacement. The first end 611A is the end of the scale 611 close to the first support plate 63, and the second end 611B is the end of the scale 611 close to the second support plate 64.

[0066] Among them, the position of the supporting roller 2 on the rotating shaft 61 before and after replacement is the same, which can ensure that the supporting roller 2 can return to its original position every time it is replaced, reducing the product quality fluctuations caused by position deviation. Moreover, after each replacement of the supporting roller 2, there is no need to re-adjust the production line, reducing the preparation time and cost before production.

[0067] In some embodiments, to ensure the parallelism between the embossing roller 3 and the supporting roller 2, please refer to Figure 3 , the tape embossing device 100 further includes a first mounting plate 71 and a second mounting plate 72. The first mounting plate 71 is slidably disposed on the mounting seat 1, and the second mounting plate 72 is rotatably disposed on the first mounting plate 71 through a fixed shaft 73. The axis of the fixed shaft 73 is perpendicular to the mounting surface A of the mounting seat 1. The embossing roller 3 is rotatably disposed on the second mounting plate 72, and the second mounting plate 72 can drive the embossing roller 3 to rotate around the fixed shaft 73 to adjust the parallelism between the embossing roller 3 and the supporting roller 2. Specifically, the second mounting plate 72 is rotatably disposed on the first mounting plate 71 through the fixed shaft 73, and the embossing roller 3 is rotatably disposed on the second mounting plate 72. Workers can rotate the second mounting plate 72 to drive the embossing roller 3 to rotate around the fixed shaft 73, and the rotation of the embossing roller 3 around the fixed shaft 73 can determine the parallelism between the embossing roller 3 and the supporting roller 2.

[0068] In this way, on the one hand, the adjustment of the parallelism ensures the uniformity and consistency of the embossing process, which can improve the appearance and performance of the product. The precise adjustment of the parallelism reduces the waste products caused by uneven embossing, lowering the production cost. By ensuring the parallelism between the embossing roller 3 and the supporting roller 2, the vibration and noise during the operation of the equipment are reduced, improving the overall stability of the equipment; on the other hand, workers can directly adjust the parallelism by rotating the second mounting plate 72, simplifying the calibration process and improving the operation efficiency. Workers can complete the parallelism adjustment without complex tools or professional knowledge, reducing the operation difficulty.

[0069] Exemplarily, the fixed shaft 73 can adopt a pin shaft, a quick connection shaft or a titanium alloy pin shaft with a flat key, etc., which allows relative movement between components. Taking the pin shaft as an example, the pin shaft provides a simple and reliable way to connect or fix two components, allowing them to move relative to each other in a fixed position. Moreover, compared with other complex connection methods, the design and manufacturing cost of the pin shaft is lower, and it is easy to install and maintain. In addition, the pin shaft is usually designed to be detachable. Once worn or damaged, it can be easily and quickly replaced, reducing the maintenance cost and downtime.

[0070] It should be noted that the material of the pin shaft can adopt materials with good strength and wear resistance, such as high-strength plastic pin shafts, carbon fiber pin shafts or ceramic pin shafts. The present application does not limit the material of the pin shaft.

[0071] In some embodiments, please refer to Figure 3and Figure 7 , the first driving assembly 4 includes a first driving motor 41, a driving block 42, a rotating disk 43 and a roller 44. The first driving motor 41 can drive the rotating disk 43 to rotate. The roller 44 is arranged on the rotating disk 43 deviating from the center of the rotating disk 43. The driving block 42 is connected to the first mounting plate 71. A mounting groove 421 is provided in a section of the driving block 42 close to the rotating disk 43 along a direction perpendicular to the first direction F1. The notch of the mounting groove 421 faces the first driving motor 41. The roller 44 is rotatably arranged in the mounting groove 421. The first driving assembly 4 further includes a guiding member 74. The guiding member 74 is arranged on the mounting surface A along the first direction F1. The guiding member 74 is connected to the first mounting plate 71 so that the driving block 42 can move along the first direction F1.

[0072] Specifically, the rotating disk 43 is arranged on the first driving motor 41 and connected to the motor shaft of the first driving motor 41. The roller 44 is arranged on the rotating disk 43 deviating from the center of the rotating disk 43. When the rotating disk 43 rotates following the motor shaft, the relative position of the roller 44 in the first direction F1 can move up and down following the rotation of the rotating disk 43. The driving block 42 is provided with the mounting groove 421. The roller 44 rotates relative to the driving block 42 in the mounting groove 421. The driving block 42 moves along the first direction F1 following the roller 44. The guiding member 74 is arranged on the mounting surface A and connected to the first mounting plate 71, which can limit the moving direction of the driving block 42.

[0073] First of all, the above transmission system has a compact structure and occupies a small space, which is suitable for realizing efficient and precise linear motion in a limited space; secondly, by adjusting the rotation speed and direction of the first driving motor 41, the moving speed and direction of the driving block 42 can be controlled, which is convenient for realizing automatic control; finally, the rotation of the roller 44 in the mounting groove 421 and the limitation of the guiding member 74 ensure the smooth movement of the driving block 42 along the first direction F1, reducing the vibration and noise during the movement process.

[0074] In some embodiments, in order to be able to visually measure the moving distance of the embossing roller 3, please refer to Figure 7 , the tape embossing device 100 further includes a reading head 8 and a grating scale 9. The grating scale 9 is arranged on one side of the first mounting plate 71 close to the mounting seat 1. The reading head 8 is arranged corresponding to the grating scale 9 on one side of the mounting seat 1 close to the first mounting plate 71. The grating scale 9 moves following the first mounting plate 71. The reading head 8 can measure the moving distance of the grating scale 9.

[0075] First of all, controlling the position of the embossing roller 3 helps to improve the embossing quality and consistency, reducing product defects caused by inaccurate positions. By controlling the movement of the embossing roller 3, the waste products caused by position deviation are reduced, and the production cost is lowered.

[0076] Secondly, the grating scale 9 has relatively high measurement accuracy and resolution compared with magnetic grating scales and ball grating scales, and the optical signals of the grating scale 9 are relatively less susceptible to electromagnetic interference, which makes them more reliable in an environment with a relatively concentrated electronic equipment. In addition, the installation of the grating scale 9 is usually relatively simple, and due to the precision of its structure, the maintenance requirements are relatively low. The present application does not limit the material of the grating scale.

[0077] Optionally, a motor placement groove 11 is provided on the mounting base 1, and the second drive motor 51 can be placed in the motor placement groove 11.

[0078] It can be understood that, compared with not providing the motor placement groove 11, the motor placement groove 11 provides a safe storage location, avoiding accidental injuries or equipment damage that may be caused by the random placement of the motor during the replacement of the support roller 2. The weight and volume of the motor may be relatively large, and improper storage may cause safety problems such as tripping and collision of personnel; the use of the motor placement groove 11 simplifies the process of replacing the support roller 2, reduces the time for finding a suitable storage location, and makes the replacement process faster and more efficient; at the same time, the fixed-position storage also helps the implementation of maintenance and inspection work. The specific motor placement groove 11 can be used as a fixed storage point for the motor, facilitating daily maintenance and management. When it is necessary to inspect or repair the motor, it can be directly carried out in the placement groove without the need to move the motor additionally, saving time and effort.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
