Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a material strip composite machine based on adjustable belt path. Background Technology

[0002] In battery manufacturing, the material strip lamination process is a crucial step that directly affects battery performance and safety. Generally, during electrode manufacturing, carbon ribbons are bonded to the surface of foil, or other material strips are bonded to the surface of foil, creating grooves to reserve space. A carbon layer is then coated in these grooves, thus completing the material strip lamination process.

[0003] During the research process, the following technical problems were found in the strip lamination process: Strip lamination refers to the lamination between strip rolls. When the strip is unwound, it is lamination along its length. However, due to the large length of the strip, it is easy to cause belt deviation, which in turn affects the lamination position between the strips. Since the bonding position between the strips is designed according to the process design requirements, it is inevitable to change the entire belt path during strip lamination, thereby changing the bonding position along the width of the strip. However, the change of the belt path will cause the installation position of the components in the production equipment to be reassembled, affecting the battery manufacturing efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a tape laminating machine based on an adjustable tape track, which can easily adjust the tape track, ensure good lamination quality, and is compatible with laminating rolls of various sizes.

The first winding mechanism peels off and winds up the protective film on the second tape.

[0007] When the width of the first strip to be laminated changes, the lamination position of the first strip along its width direction needs to be adjusted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is for reference. Figures 1 to 2 This invention describes a tape laminating machine based on an adjustable tape track, according to an embodiment of the present invention.

[0024] like Figure 1 and Figure 2As shown, the adjustable belt track material laminating machine according to the present invention can be applied in battery manufacturing production lines. It can easily and quickly adjust the belt track to ensure good lamination quality of the material strip. In addition, it can be compatible with the lamination of material rolls of various widths. Therefore, it has the advantages of reasonable structural design, high adjustment efficiency and good compatibility.

[0025] The adjustable conveyor belt laminating machine has a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are arranged perpendicularly to each other. In this embodiment, it is assumed that the first direction is the front-to-back direction, the second direction is the up-down direction, and the third direction is the left-to-right direction.

[0026] The adjustable belt laminating machine includes a first unwinding mechanism 100, a second unwinding mechanism 200, a laminating pressure roller mechanism 300, a first winding mechanism 500, and a second winding mechanism 400.

[0027] The first unwinding mechanism 100 is configured to unwind the first strip 800. The first unwinding mechanism 100 includes a fixed base 140, an unwinding shaft assembly 110, and a correction assembly 120. The correction assembly 120 is mounted on the unwinding shaft assembly 110 and is configured to correct the deviation of the first strip 800. The unwinding shaft assembly 110 is slidably connected to the fixed base 140 and is configured to move linearly relative to the fixed base 140 along its own axial direction. In this case, the correction assembly 120 can move linearly along with the unwinding shaft assembly 110, thereby simultaneously adjusting the positions of the unwinding shaft assembly 110 and the correction assembly 120 relative to the fixed base 140. The axial direction of the unwinding shaft assembly 110 is the third direction.

[0028] It is understood that the correction component 120 is an existing structure and can be either a photoelectric correction system or an ultrasonic correction system. The correction component 120 can perform correction processing on the first material strip 800 released by the unwinding shaft assembly 110 to adjust the lateral position of the first material strip 800 in real time. Those skilled in the art should clearly understand the specific structure and working principle of the correction component 120, which will not be described in detail here. The specific shape of the fixing seat 140 is not limited, as long as it can provide support for the unwinding shaft assembly 110 and the correction component 120. Of course, it is not excluded that in other embodiments, the first unwinding mechanism 100 does not include the correction component 120; or, the correction component 120 is set in other positions, not on the unwinding shaft assembly 110.

[0029] Specifically, the unwinding shaft assembly 110 includes an unwinding shaft 111, a rotary drive, and a mounting base 114. The mounting base 114 and the fixed base 140 are slidably connected via a guide rail slider pair 150. The rotary drive is fixedly mounted on the mounting base 114 and can move along with the mounting base 114. The output end of the rotary drive is fixedly connected to the unwinding shaft 111, and the rotary drive can drive the unwinding shaft 111 and the material roll on it to rotate together, allowing the unwinding shaft 111 to continuously unwind a long first strip 800. The web guiding assembly 120 can be fixedly connected to the mounting base 114 or mounted on the unwinding shaft 111 via a bracket. The unwinding shaft 111 can rotate relative to the web guiding assembly 120 around its own axis.

[0030] In this embodiment, the upper part of the fixed base 140 is provided with two guide rails extending along a third direction. Correspondingly, the mounting base 114 is located above the fixed base 140, and the lower part of the mounting base 114 is provided with a slider. The slider is slidably connected to the guide rails along a third direction, so that the mounting base 114 can drive the rotary drive component, the unwinding shaft 111, and the correction assembly 120 to move linearly along a third direction. The rotary drive component includes a drive motor 112, a reducer 113, and a transmission shaft. The output shaft of the drive motor 112 is fixedly connected to the power input shaft of the reducer 113. The power output shaft of the reducer 113 is fixedly connected to one end of the transmission shaft. The transmission shaft is mounted on the mounting base 114 through a bearing seat 115. The other end of the transmission shaft is fixedly connected to one end of the unwinding shaft 111 and is coaxially arranged. The unwinding shaft 111 extends along a third direction, and a roll with the first material strip 800 wound on it can be mounted.

[0031] The second unwinding mechanism 200 is configured to unwind the second strip. At least one second unwinding mechanism 200 is provided. It is understood that the second unwinding mechanism 200 is an existing structure, and its specific structure can be consistent with the specific structure of the unwinding shaft assembly 110. During operation, the second unwinding mechanism 200 can continuously release a long second strip. The first strip 800 can be a foil strip, and the second strip can be a carbon ribbon or other strips that can be laminated onto the first strip 800. The unwinding shaft assembly 110 moves axially relative to the fixed seat 140 until the first strip 800 and the second strip are laminated along a preset trajectory.

[0032] The composite pressure roller mechanism 300 is configured to press the first strip 800 and the second strip into a composite strip. It is understood that the composite pressure roller mechanism 300 is an existing structure, comprising two pressure rollers rotating in opposite directions, spaced apart to define a pressing channel. When the first strip 800 and the second strip are fed into the pressing channel, the two pressure rollers apply pressure to them, causing them to press together under the set pressure, thus forming a composite strip.

[0033] The first winding mechanism 500 is configured to wind up the protective film on the second strip. The first winding mechanism 500 has at least one component. It is understood that the second strip has a protective film laminated on it, which provides protection during storage. When the second strip is laminated with the first strip 800, the first winding mechanism 500 peels off and winds up the protective film on the second strip. The first winding mechanism 500 is a conventional winding machine, and those skilled in the art should clearly understand its specific structure and working principle; therefore, it will not be described in detail.

[0034] The second winding mechanism 400 is configured to wind up the composite tape. It is understood that the second winding mechanism 400 is an existing winding machine, and those skilled in the art should understand its specific structure and working principle; therefore, it will not be described in detail. During operation, the second winding mechanism 400 can wind up the composite tape rolled out from the roller channel for subsequent storage and unwinding. The installation positions of the first unwinding mechanism 100, the second unwinding mechanism 200, the composite pressure roller mechanism 300, the first winding mechanism 500, and the second winding mechanism 400 can be set according to the actual layout.

[0035] During the conveyor belt process, the conveyor belt paths of the first material belt 800 and the second material belt can form a tangent point at the feeding position of the composite pressure roller mechanism 300, and the conveyor belt paths of the composite belt and the protective film can form a tangent point at the discharging position of the composite pressure roller mechanism 300, so that the first unwinding mechanism 100, the second unwinding mechanism 200, the first winding mechanism 500 and the second winding mechanism 400 all have their own winding and unwinding paths.

[0036] In the operation of the adjustable tape laminating machine provided in this embodiment of the invention, the first unwinding mechanism 100, the second unwinding mechanism 200, the composite pressure roller mechanism 300, the first winding mechanism 500, and the second winding mechanism 400 are activated. The first unwinding mechanism 100 unwinds a long first tape 800 towards the composite pressure roller mechanism 300, and the second unwinding mechanism 200 unwinds a long second tape towards the composite pressure roller mechanism 300. The first tape 800 and the second tape simultaneously enter the roller pressing channel of the composite pressure roller mechanism 300. At this time, the composite pressure roller mechanism 300 applies a certain roller pressing action to the first tape 800 and the second tape, allowing the first tape 800 and the second tape to be laminated together, thereby producing a long composite tape. After the composite tape exits from the roller pressing channel of the composite pressure roller mechanism 300, the first winding mechanism 500 peels off and winds up the protective film on the second tape, while the second winding mechanism 400 winds up the composite tape.

[0037] When the width of the first strip 800 needs to be changed according to process requirements (that is, the width of the first strip 800 to be laminated changes), the lamination position of the first strip 800 along its width direction needs to be adjusted. Specifically, by driving the unwinding shaft assembly 110 to move the correction assembly 120 relative to the fixed seat 140 along the axial direction of the unwinding shaft assembly 110, the tape travel trajectory of the first strip 800 can be easily and quickly adjusted, so that the first strip 800 and the second strip can be laminated on the preset trajectory. By adjusting the lamination position of the first strip 800 along its own width direction, the first strip 800 can better fit with the second strip, meet the lamination requirements of the first strip 800, and ensure a good lamination effect between the first strip 800 and the second strip. Ultimately, this can improve the compatibility of the tape laminator based on adjustable tape travel trajectory and enable lamination of tape rolls with various widths.

[0038] Furthermore, when adjusting the composite position of the first material strip 800, the operator does not need to disassemble and reassemble the various components of the material strip composite machine based on the adjustable belt track. This reduces the difficulty of operation, shortens the time for adjusting the first material strip 800, and helps to improve the efficiency of electrode manufacturing.

[0039] In addition, the correction component 120 can move together with the unwinding assembly 110. When the material roll on the unwinding assembly 110 is replaced, the correction component 120 can still apply the correction effect to the first material strip 800 on the unwinding assembly 110, which can prevent the first material strip 800 from having a composite positional shift due to the belt travel offset. Moreover, there is no need to adjust the position of the correction component 120 relative to the unwinding assembly 110.

[0040] Of course, it is not excluded that in other embodiments, the tape laminating machine based on the adjustable tape track does not include the second winding mechanism 400. In this case, the composite tape coming out of the roller pressing channel is sent to the next station, such as the cutting station.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the first unwinding mechanism 100 also includes a detection component 130. The detection component 130 is mounted on the unwinding shaft assembly 110 and can move along the third direction with the unwinding shaft assembly 110. Furthermore, the detection component 130 is configured to detect the width of the first strip 800. Specifically, the correction component 120 and the detection component 130 are arranged parallel to the unwinding shaft assembly 110. The correction component 120 and the detection component 130 are sequentially arranged along the unwinding path of the unwinding shaft assembly 110. Therefore, during the continuous unwinding of the first strip 800 by the unwinding shaft assembly 110, the correction component 120 first corrects the deviation of the first strip 800. After correcting the deviation, the detection component 130 then detects the width of the first strip 800 to obtain its width data.

[0042] In this embodiment, the correction component 120 and the detection component 130 are both located above the unwinding assembly 110, and the correction component 120 and the detection component 130 are arranged sequentially along the first direction.

[0043] Understandably, the detection component 130 can employ a vision system or a laterally movable laser rangefinder to detect the width of the first strip 800. The detection component 130 can be equipped with a display screen to clearly show the width of the first strip 800. Alternatively, the detection component 130 can be electrically connected to an external host computer to transmit the collected data. After obtaining the width of the first strip 800 through the detection component 130, the operator can adjust the position of the first strip 800 on the unwinding assembly 110, the web guiding assembly 120, the detection component 130, and the unwinding assembly 110 along a third direction based on the width of the first strip 800. Of course, without the detection component 130, the operator can obtain the width of the first strip 800 from the specifications of the roll.

[0044] In some embodiments, the first unwinding mechanism 100 further includes a drive assembly. The output end of the drive assembly is connected to the unwinding shaft assembly 110, and the drive assembly is configured to drive the unwinding shaft assembly 110 to move a set distance along the axial direction of the unwinding shaft assembly 110 according to the width dimension of the first strip 800.

[0045] Understandably, in some examples, the drive component is a hand-cranked slide, which is located between the fixed base 140 and the mounting base 114. The hand-cranked slide is fixedly mounted on the fixed base 140 and the slide of the hand-cranked slide is fixedly connected to the mounting base 114. The operator operates the hand-cranked slide to precisely adjust the position of the unwinding assembly 110 in the third direction.

[0046] In other examples, the drive assembly is an electrically driven linear drive device such as a linear module. The linear module is connected to the fixed base 140, and the slide of the linear module is connected to the mounting base 114. The linear module can automatically adjust the position of the unwinding shaft assembly 110 in the third direction with high precision. When the detection assembly 130 is provided, after the detection assembly 130 completes the width dimension detection of the first strip 800, the drive assembly can drive the unwinding shaft assembly 110 to move a certain distance in the third direction according to the detection result of the detection assembly 130, thereby automatically adjusting the composite position of the first strip 800 and achieving the effect of quickly adjusting the direction and positioning of the entire roll of the first strip 800 on the unwinding shaft 111.

[0047] For example, when the width of the first strip 800 increases, the drive assembly operates, causing the unwinding assembly 110 to move along one side of a third direction; when the width of the first strip 800 decreases, the drive assembly operates, causing the unwinding assembly 110 to move along the other side of a third direction. The moving distance of the unwinding assembly 110 is determined based on the change in the width of the first strip 800.

[0048] In some embodiments, the first unwinding mechanism 100 and the second unwinding mechanism 200 are located at the starting end of the composite pressure roller mechanism 300 along the belt-carrying direction, and the second winding mechanism 400 and the first winding mechanism 500 are located at the ending end of the composite pressure roller mechanism 300 along the belt-carrying direction. The belt-carrying direction is combined in the composite pressure roller mechanism 300 and separated at the starting end and the ending end, respectively.

[0049] The composite pressure roller mechanism 300 has a roller pressing channel extending along a first direction. The second unwinding mechanism 200 and the first winding mechanism 500 form a one-to-one traction and unwinding relationship through the second material strip. Multiple second unwinding mechanisms 200 and multiple first winding mechanisms 500 are respectively connected through corresponding second material strips, and the second material strips are composited in the roller pressing channel without intersecting.

[0050] Understandably, the first unwinding mechanism 100 unwinds the first strip 800, and the second unwinding mechanism 200 unwinds the second strip. Both the first and second strips have their own travel paths and move towards the composite pressure roller mechanism 300. Before entering the roller pressing channel, the first and second strips are separated and do not contact each other. Upon entering the roller pressing channel, the first and second strips come into contact and adhere to each other, and are then composited within the roller pressing channel. The first winding mechanism 500 winds up the protective film on the second strip, and the second winding mechanism 400 winds up the composite strip. After leaving the roller pressing channel, the composite strip and the protective film have their own travel directions, meaning they remain separated and do not contact each other.

[0051] like Figure 1 As shown, the first unwinding mechanism 100 and the second unwinding mechanism 200 are located on one side of the composite pressure roller mechanism 300 along the first direction, and the second winding mechanism 400 and the first winding mechanism 500 are located on the other side of the composite pressure roller mechanism 300 along the first direction. The first unwinding mechanism 100 and the second unwinding mechanism 200 perform unwinding operations on the same side of the composite pressure roller mechanism 300, while the first winding mechanism 500 and the second winding mechanism 400 perform winding operations on the same side of the composite pressure roller mechanism 300.

[0052] In a specific embodiment, such as Figure 1 As shown, the composite pressure roller mechanism 300 has a roller pressing channel extending along a first direction, and two second unwinding mechanisms 200 are provided, with the two second unwinding mechanisms 200 respectively located on both sides of the roller pressing channel along a second direction. Two first winding mechanisms 500 are provided, with the two first winding mechanisms 500 respectively located on both sides of the roller pressing channel along a second direction.

[0053] In this embodiment, the first unwinding mechanism 100 and the two second unwinding mechanisms 200 operate simultaneously. The first strip 800 is then laminated with two second strips under the operation of the composite pressure roller mechanism 300. Both sides of the first strip 800 are laminated with second strips, resulting in a three-layer composite strip structure. After the composite strip exits the roller channel, the two first winding mechanisms 500 simultaneously perform winding operations, respectively peeling off and winding the protective film from the second strips on both sides of the first strip 800.

[0054] In another specific embodiment, the composite pressure roller mechanism 300 has a roller pressing channel extending along a first direction, a second unwinding mechanism 200 is provided, a first winding mechanism 500 is provided, and the second unwinding mechanism 200 and the first winding mechanism 500 are both located on the same side of the roller pressing channel along the second direction.

[0055] With this configuration, during the operation of the first unwinding mechanism 100 and the second unwinding mechanism 200, the first strip 800 will combine with the second strip to form a composite strip with a double-layer structure. The first winding mechanism 500 will peel off and wind up the protective film on the second strip after the composite strip leaves the roller channel.

[0056] In some embodiments, such as Figure 1 As shown, the adjustable conveyor belt laminator also includes a frame 600. The frame 600 includes a side plate 610, which extends longitudinally along a first direction, widthwise along a second direction, and thicknesswise along a third direction. The side plate 610 has a mounting through hole extending axially along the third direction. The size of the mounting through hole allows the unwinding shaft 111 to pass through it. A fixed base 140, a mounting base 114, and a rotary drive are located on one side of the side plate 610 along the third direction, while the unwinding shaft 111 is located on the other side of the side plate 610 along the third direction.

[0057] Furthermore, the unwinding shaft 111, the second unwinding mechanism 200, the composite pressure roller mechanism 300, the second winding mechanism 400, and the first winding mechanism 500 are located on the same side of the side plate 610 along the axial direction (i.e., the third direction) of the unwinding shaft assembly 110. The side plate 610 provides support and mounting positions for the first unwinding mechanism 100, the second unwinding mechanism 200, the composite pressure roller mechanism 300, the second winding mechanism 400, and the first winding mechanism 500.

[0058] The unwinding shaft 111 is configured to move along its own axial direction with the side plate 610 as the reference plane to adjust the relative position difference between itself and the second unwinding mechanism 200, the second winding mechanism 400 and the first winding mechanism 500 in the axial direction (i.e., the third direction) of the unwinding shaft 111.

[0059] It is understandable that the unwinding shaft 111, passing through the side plate 610, allows for adjustment of the relative distance between the material roll on the unwinding shaft 111 and the side plate 610. This enables rapid adjustment of the belt path of the first material strip 800 by simply adjusting the distance between the unwinding shaft 111 and the side plate 610 along a third direction. With the side plate 610 as the reference plane, the relative positional differences in the third direction between the unwinding shaft 111 and the second unwinding mechanism 200, the second winding mechanism 400, and the first winding mechanism 500 on the frame 600 are adjusted according to the width of the first material strip 800.

[0060] In some embodiments, such as Figure 1As shown, the composite pressure roller mechanism 300 has a first tension roller assembly 710 and a second tension roller assembly 720 on one side along a first direction. The first tension roller assembly 710 is configured to tension the first material strip 800, and the second tension roller assembly 720 is configured to tension the second material strip. The first tension roller assembly 710 can precisely control the tension on the first material strip 800, and the second tension roller assembly 720 can adjust the tension of the second material strip in real time, thereby ensuring that the surfaces of the first material strip 800 and the second material strip are free from wrinkles or deformation, and preventing the first material strip 800 and the second material strip from easily breaking, which is beneficial to improving the composite quality.

[0061] The composite pressure roller mechanism 300 has a third tension roller assembly 730 and a fourth tension roller assembly 740 on the other side along the first direction. The third tension roller assembly 730 is configured to tension the composite belt, and the fourth tension roller assembly 740 is configured to tension the protective film. The third tension roller assembly 730 can precisely control the tension of the composite belt, and the fourth tension roller assembly 740 can adjust the tension of the protective film in real time, thereby preventing the composite belt and the protective film from wrinkling or breaking easily.

[0062] It is understood that the number of the first tension roller assembly 710, the second tension roller assembly 720, the third tension roller assembly 730, and the fourth tension roller assembly 740 is not limited to one. By setting corresponding tension roller assemblies on each belt track, and by forming different included angles with the composite axis extending along the first direction of the composite pressure roller mechanism 300, the first tension roller assembly 710, the second tension roller assembly 720, the third tension roller assembly 730, and the fourth tension roller assembly 740 can separate the belt paths of the first material strip 800, the second material strip, the composite belt, and the protective film. This avoids belt crossing during the bonding of the first material strip 800 and the second material strip, as well as during the winding of the composite belt and the protective film, which would affect the winding and unwinding operations. This allows for the rapid separation of the primary and secondary belt tracks, facilitating the continuous release of the first material strip 800 and the second material strip through the unwinding operation. This allows the first material strip 800 and the second material strip to smoothly enter the roller pressing channel, and the composite belt and the waste protective film to be recovered through the winding operation.
