Technical Field

[0001] The present invention relates to the technical field of lithium battery gluing, and particularly to a tension stabilizing system for a glue coating tape path. Background Art

[0002] In the process of lithium battery manufacturing, there is a process of gluing the lithium battery electrode sheet. During the gluing process, the stable operation of the glue coating film path is the key to manufacturing high-quality lithium batteries.

[0003] Compared with the conventional path, the glue coating film path has more stringent requirements for tension control, so it is necessary to better control the stability of the tension of the glue coating film path. However, in the actual processing process, the stability of the tension of the glue coating film path is somewhat poor, which easily causes phenomena such as wrinkles, breakage or fracture of the glue coating film, affecting the quality and efficiency of lithium battery gluing processing. Summary of the Invention

[0006] The fixed roller assembly, the glue coating roller assembly and the floating roller assembly are sequentially distributed along the transmission direction of the glue coating tape path. The fixed roller assembly is used to transmit the glue coating tape path. The glue coating roller assembly and the floating roller assembly can move relatively or away from each other. The floating roller assembly is used to cooperate with the glue coating roller assembly to synchronously adjust the tension of the glue coating tape path so that the glue coating tape path is in a state of stable tension.

[0007] In some embodiments of the present invention, the fixed roller assembly includes a first fixed roller and a second fixed roller.

The glue coating roller assembly has a first wrap angle with the path between the first fixed roller and the second fixed roller, and the floating roller assembly has a second wrap angle with the path between the first fixed roller and the second fixed roller. During gluing, the glue coating roller assembly and the floating roller assembly move relatively or away from each other to keep the first wrap angle and the second wrap angle equal.

[0009] In some embodiments of the present invention, anti-sticking portions are provided on the outer peripheral walls of the first fixed roller and the second fixed roller, and the anti-sticking portions are in sliding contact with the tape coating path.

[0010] In some embodiments of the present invention, the first fixed roller and the floating roller assembly are arranged on the same side, and the second fixed roller and the glue coating roller assembly are arranged on the same side.

[0011] In some embodiments of the present invention, the glue coating roller assembly includes a glue coating roller member and a first driving member. The glue coating roller member is rotatably connected to the first driving member. The glue coating roller member has a first moving direction, and the first driving member is used to drive the glue coating roller member to reciprocate along the first moving direction, so as to drive the glue coating roller member to slide into contact with or disengage from the tape coating path.

[0014] In some embodiments of the present invention, the fixed roller assembly includes a first fixed roller, and the rotation direction of the glue coating roller member is opposite to the rotation direction of the first fixed roller.

[0015] In some embodiments of the present invention, the glue coating roller member is in sliding contact with one side of the two opposite sides of the tape coating path, and the floating roller member is in sliding contact with the other side of the two opposite sides of the tape coating path.

[0016] The beneficial effects of the present invention are as follows: Different from the prior art, the tape coating path tension stabilizing system disclosed in the present invention transmits the tape coating path through the fixed roller assembly.

With such a setting, it is effectively avoided that the tape coating path wrinkles, breaks or fractures during the production process, so as to better improve the production efficiency and production quality.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0029] The present invention provides a coating tape path tension stabilizing system. Referring to Figure 1 , this coating tape path tension stabilizing system 100 is used in the transmission of the coating tape path 150 to adjust the tension of the coating tape path 150, so that the coating tape path 150 can always be kept in a tensioned state during the conveying process to ensure the stable conveying of the strip material and thus ensure the quality of production and processing.

[0030] Referring to Figures 1 to 5 , the coating tape path tension stabilizing system 100 includes a fixed roller assembly 110, a coating roller assembly 120, and a floating roller assembly 130. Among them, the fixed roller assembly 110, the coating roller assembly 120, and the floating roller assembly 130 are sequentially distributed along the transmission direction of the coating tape path 150. The fixed roller assembly 110 is used to transmit the coating tape path 150, and the coating roller assembly 120 and the floating roller assembly 130 can move relatively or away from each other. The floating roller assembly 130 is used to cooperate with the coating roller assembly 120 to synchronously adjust the tension of the coating tape path 150 so that the coating tape path 150 is in a state of stable tension.

[0031] Based on the above solution, the tension stabilization system 100 of the coating tape path transmits the coating tape path 150 through the fixed roller assembly 110, and synchronously adjusts the tension of the coating tape path 150 by the floating roller assembly 130 and the coating roller assembly 120 during the transmission of the coating tape path 150, so as to control the tension of the coating tape path 150, make the coating tape path 150 always keep in a tensioned state, ensure the stability of the tension of the coating tape path 150. Set like this to effectively avoid phenomena such as the coating tape path 150 becoming loose, wrinkled, damaged or broken during the production process, so as to better improve production efficiency and production quality.

[0032] Continue to refer to Figures 1 to 5 , in some embodiments of the present invention, the fixed roller assembly 110 includes a first fixed roller 111 and a second fixed roller 112, there is a tension area 140 between the first fixed roller 111 and the second fixed roller 112, when coating, the coating roller assembly 120 and the floating roller assembly 130 move relatively or away from each other to keep the length of the guiding path between the first fixed roller 111 and the second fixed roller 112 unchanged.

[0033] For example, before the coating roller assembly 120 cooperates with the floating roller assembly 130 to adjust the coating tape path 150, the guiding path length of the coating tape path 150 when it is in the tension area 140 can be preset as L1. When the coating roller assembly 120 cooperates with the floating roller assembly 130 to adjust the tension of the coating tape path 150, the guiding path length of the coating tape path 150 when it is in the tension area 140 can be preset as L2. During the process of the coating roller assembly 120 and the floating roller assembly 130 synchronously adjusting the tension of the coating tape path 150, the guiding path length L2 and the guiding path length L1 are always equal, that is, ensuring that the tape length remains unchanged when the coating tape path 150 is in the tension area 140. In other words, no matter how the conveying direction of the coating tape path 150 is adjusted in the tension area 140, under the synchronous adjustment of the coating roller assembly 120 and the floating roller assembly 130, it is only necessary to ensure that the tape length remains unchanged when the coating tape path 150 is in the tension area 140, so that the coating tape path 150 can always be kept in a state of stable tension.

[0034] Set like this, so that the coating roller assembly 120 and the floating roller assembly 130 can flexibly adjust the tension of the coating tape path 150 according to the on-site production and processing environment, and ensure that the tension of the coating tape path 150 always remains in a stable state, so as to effectively avoid phenomena such as the coating tape path 150 becoming loose, wrinkled, damaged or broken.

[0035] Continue to refer to Figures 1 to 5, in some other embodiments of the present invention, the fixed roller assembly 110 includes a first fixed roller 111 and a second fixed roller 112. There is a first wrap angle between the coating roller assembly 120 and the path between the first fixed roller 111 and the second fixed roller 112. There is a second wrap angle between the floating roller assembly 130 and the path between the first fixed roller 111 and the second fixed roller 112. When applying glue, the coating roller assembly 120 and the floating roller assembly 130 move relative to or away from each other to keep the first wrap angle and the second wrap angle equal.

[0036] With such a setting, by defining that the first wrap angle and the second wrap angle are equal, the tension of the coating tape path 150 can be ensured, and the stability of the tension of the coating tape path 150 can be well improved, so as to effectively avoid phenomena such as the coating tape path 150 becoming loose, wrinkled, damaged or broken, and improve the quality and efficiency of production and processing.

[0037] Different from the mode of controlling the equal length of the path length L1 and the path length L2, by controlling the first wrap angle and the second wrap angle to be equal, the length relationship between the first tension section 151 and the second tension section 152 does not need to be considered. That is, without ensuring that the tape length remains unchanged, the coating roller assembly 120 and the floating roller assembly 130 can more flexibly adjust the tension of the coating tape path 150, so as to be able to adjust the tension of the coating tape path 150 and keep the tension of the coating tape path 150 in a stable state, as long as the first wrap angle and the second wrap angle are always equal during the process of controlling the tension of the coating tape path 150.

[0038] It can be understood that the lengths of the first tension section 151 and the second tension section 152 can be equal or not equal. For example, the length of the first tension section 151 can be greater than the length of the second tension section 152, and the length of the first tension section 151 can also be less than the length of the second tension section 152.

[0039] The ranges of the first wrap angle and the second wrap angle can both be within 0 - 90°. For example, the first wrap angle can be represented by θ1, the second wrap angle can be represented by θ2, and θ1 and θ2 can both be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°.

[0040] Continue to refer to Figures 1 to 5 , anti-sticking parts 113 are provided on the outer peripheral walls of the first fixed roller 111 and the second fixed roller 112, and the anti-sticking parts 113 are in sliding contact with the coating tape path 150. With such a setting, the frictional force between the coating tape path 150 and the fixed roller member 111 is effectively reduced, so that the coating tape path 150 can be conveyed more smoothly, and the phenomenon of the coating tape path 150 being damaged or cut is reduced, so as to improve the quality of production and processing.

[0041] Both the first fixed roller 111 and the second fixed roller 112 can be made of rigid materials or other materials with smooth performance, and specific limitations are not made here.

[0042] The first fixed roller 111 and the floating roller assembly 130 are arranged on the same side, and the second fixed roller 112 and the glue coating roller assembly 120 are arranged on the same side. That is to say, the glue coating roller assembly 120 and the floating roller assembly 130 are arranged on different sides. The glue coating roller assembly 120 and the floating roller assembly 130 cooperate to control the tension of the glue coating tape path 150, so as to increase the stability of the glue coating tape path 150 in a tensioned state. The glue coating roller assembly 120 and the floating roller assembly 130 move relative to each other to be able to press against different sides of the glue coating tape path 150. On the one hand, it can increase the contact area with the glue coating tape path 150, which is beneficial to enhancing the control force on the glue coating tape path 150, and more advantageously drives the glue coating tape path 150 to be in a stable tensioned state. On the other hand, to a certain extent, it can also increase the contact force between the first fixed roller 111 and the floating roller assembly 130 and the glue coating tape path 150, so as to ensure the smooth transmission of the glue coating tape path 150.

[0043] In addition, the first fixed roller 111 and the floating roller assembly 130 are both located on the same side, and the second fixed roller 112 and the glue coating roller assembly 120 are both located on the same side. In this way, it is convenient to control the tension of the glue coating tape path 150 on both sides of the glue coating tape path 150, so as to accurately control the tension of the glue coating tape path 150, make the tension control of the glue coating tape path 150 by the glue coating roller assembly 120 and the floating roller assembly 130 more stable, and thus improve the stability of the tension of the glue coating tape path 150.

[0044] Continue to refer to Figures 1 to 5 , the glue coating roller assembly 120 includes a glue coating roller member 121 and a first driving member 122. The glue coating roller member 121 is rotatably connected to the first driving member 122. The glue coating roller member 121 has a first moving direction, and the first driving member 122 is used to drive the glue coating roller member 121 to reciprocate along the first moving direction, so as to drive the glue coating roller member 121 to slide into contact with or disengage from the glue coating tape path 150.

[0045] The floating roller assembly 130 includes a floating roller member 131 and a second driving member 132. The floating roller member 131 is rotatably connected to the second driving member 132. The floating roller member 131 has a second moving direction, and the second driving member 132 is used to drive the floating roller member 131 to reciprocate along the second moving direction.

[0046] With such a setting, the glue coating roller member 121 and the floating roller member 131 can synchronously adjust the tension of the glue coating tape path 150 and keep the tension state of the glue coating tape path 150 stable, effectively avoiding the sudden increase and decrease of the tension of the glue coating tape path 150, so as to improve the stability of the tension of the glue coating tape path 150.

[0047] Through the cooperative movement of the glue - applying roller part 121 and the floating roller part 131, the belt length of the glue - applying tape path 150 remains unchanged when it is in the tension area 140, or the first wrap angle and the second wrap angle are always equal.

[0048] Both the glue - applying roller part 121 and the floating roller assembly 130 can be steel rollers made of rigid materials, or silicone rollers. The glue - applying roller part 121 and the floating roller assembly 130 can also be other cylindrical - shaped structural members, and no specific limitation is made here.

[0049] The glue - applying roller part 121 can be rotated by a rotating cylinder or a rotating motor, so that the glue - applying roller part 121 can perform circumferential movement. The floating roller part 131 can be rotated by a rotating cylinder or a rotating motor, so that the floating roller part 131 can perform circumferential movement to cooperate with the fixed roller assembly 110 to convey the glue - applying tape path 150 and ensure that the glue - applying tape path 150 can be normally conveyed.

[0050] The first driving part 122 and the second driving part 132 can both be linear motors, or both can be lead - screw slide - table structures. The first driving part 122 and the second driving part 132 can also be other structural members with linear - motion functions, and they are not listed one by one here.

[0051] Among them, the first moving direction is as shown by the arrow I in Figure 4 and the second moving direction is as shown by the arrow II in Figure 4 The first moving direction and the second moving direction are arranged in parallel. Such a setting can reduce the moving error during the movement of the glue - applying roller part 121 and the floating roller part 131, so that both the glue - applying roller part 121 and the floating roller part 131 can cooperate and accurately control the tension of the glue - applying tape path 150, thereby more effectively improving the stability of the tension of the glue - applying tape path 150.

[0052] The rotation direction of the glue - applying roller part 121 and the rotation direction of the floating roller part 131 can be opposite. With such a setting, on the premise of effectively avoiding abrasion to the glue - applying tape path 150, the frictional force between the glue - applying roller part 121 and the glue - applying tape path 150 is increased within a reasonable range, which is beneficial for the glue - applying roller part 121 to tension the glue - applying tape path 150 and effectively prevent the glue - applying tape path 150 from becoming loose or peeling off.

[0053] Continue to refer to Figures 1 to 5 , the fixed roller assembly 110 includes a first fixed roller 111, and the rotation direction of the glue - applying roller part 121 is opposite to the rotation direction of the first fixed roller 111. With such a setting, the glue - applying tape path 150 can obtain a better tension when entering the tension area, ensuring the stability of the transmission of the glue - applying tape path 150, more stably controlling the tension of the glue - applying tape path 150, and improving the tension stability of the glue - applying tape path 150.

[0054] Continue to refer to Figures 1 to 5 , one side of the two opposite sides of the glue application roller member 121 and the tape path 150 is in sliding contact, and the floating roller member 131 is in sliding contact with the other side of the two opposite sides of the tape path 150. With such a setting, on the one hand, it can change the transmission direction of the tape path 150 to match the layout of the on-site production environment, so as to reasonably divide the transmission direction of the tape path 150. On the other hand, it can well increase the tension on the tape path 150, so that the tape path 150 is in a stable tension state, which can well improve the transmission effect and efficiency of the tape path 150.

[0055] Continue to refer to Figures 1 to 5 , the process of the tape path tension stabilizing system 100 controlling the tension stability is as follows:

[0056] Control mode with constant tape length: After the tape path 150 runs to the specified speed, the first driving member 122 drives the glue application roller member 121 to be in sliding contact with the tape path 150, and pushes the tape path 150 to move. At the same time, the floating roller member 131 moves towards the glue application roller member 121 to cooperate with the first fixed roller 111 and the second fixed roller 112 to transmit the tape path 150. The glue application roller member 121 and the floating roller member 131 move relatively or in opposite directions to jointly adjust the tape path 150, so as to control the tape path length L1 and the tape path length L1 when the tape path 150 is in the tension area 140 to remain unchanged, so as to achieve the purpose of controlling the tape length of the tape path 150 to remain unchanged when it is in the tension area 140, thereby achieving the purpose of controlling the tension stability of the tape path 150;

[0057] Control mode with constant first wrap angle and second wrap angle: After the tape path 150 runs to the specified speed, the first driving member 122 drives the glue application roller member 121 to be in sliding contact with the tape path 150, and pushes the tape path 150 to move. At the same time, the floating roller member 131 moves towards the glue application roller member 121 to cooperate with the first fixed roller 111 and the second fixed roller 112 to transmit the tape path 150. The glue application roller member 121 and the floating roller member 131 move synchronously and adjust the tape path 150, so that the first wrap angle and the second wrap angle always remain equal, so as to ensure that the first wrap angle and the second wrap angle are constant, thereby achieving the purpose of controlling the tension stability of the tape path 150.

[0058] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
